[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a design support device that supports the selection of parts / materials for manufacturing for improving recyclability and reducing environmental load based on evaluation results of product recyclability and environmental load.
[0002]
[Prior art]
Evaluation equipment that evaluates the recyclability of products, etc. and the environmental load in the life cycle is mainly for the purpose of supporting the selection of parts and materials for manufacturing to improve the recyclability of products. In order to evaluate the performance and environmental load, for each part constituting the product, the type of material constituting the part, the mass of the material in the part, etc. are input, and based on these, the product The recycling rate and the amount of environmental impact generated from the entire life cycle are calculated.
[0003]
However, even if the recycling rate and the amount of environmental load for the product are calculated using this evaluation device, it alone will cause the environmental load to deteriorate because of what is preventing the recyclability. It is unknown whether they are present. If the evaluation results of product recyclability and environmental impact are not reflected in the selection of component materials, the evaluation itself is meaningless in the first place.
[0004]
The purpose of the evaluation is primarily to support the selection of component materials at the design stage. Therefore, in order to achieve this objective, the user is presented with the evaluation results of the recyclability and environmental impact of the product, and as a result of the evaluation, there are problems with the product in terms of recyclability and environmental impact. The user needs to be able to easily grasp how to improve.
[0005]
On the other hand, a CAD (Computer Aided Design) system is generally used at the product design stage, and the CAD data created by this CAD system includes the parts constituting the product, the quantity and the number of those parts. In addition, information representing the shape of each part is included. Therefore, using this CAD data for evaluation of product recyclability and environmental load in the life cycle is very useful for reducing the work load for data input and performing the evaluation efficiently.
[0006]
Based on the evaluation results of product recyclability and environmental impact, analyze what is hindering recyclability and what is worsening environmental impact, and provide support to improve them If it can be done, it can be said that the final purpose of recycling and environmental impact assessment is to take the process one step further and reflect the improvement results in the CAD data.
[0007]
For example, Japanese Patent Laid-Open No. 9-160959 discloses an input device that inputs design information and the like, a storage device that stores input information and criteria for determination, and an operation that performs evaluation and determination based on the information and the like. A design support method and device comprising a device and an output device that outputs design information, evaluation results, proposed changes based on the evaluation results, etc. have been disclosed, but this minimizes the cost of disassembly, disassembly, etc. It does not provide evaluation or support for the purpose of improving the recyclability of products or reducing the environmental burden in the life cycle.
[0008]

[0048]
The creation process of CAD data used in the recyclability evaluation system shown in FIG. 2 is not the gist of the present application, so the description thereof will be omitted. However, the CAD data here is general CAD data created by using the prior art. CAD data itself is not particularly characteristic.
[0049]
Generally, as shown in FIG. 3, the CAD data includes a product name (may be product identification information such as a model number), external dimensions of the product, and configuration information indicating the configuration of the product, Each component (unit) includes the part name and quantity / number of parts used in the unit, shape information indicating the shape of the part, and the like.
[0050]
Data sets that can be used as CAD data including these pieces of information, that is, data output from CAD, data to be input to CAD, such as CAD viewer data, can be handled in the same manner.
[0051]
Here, it is assumed that when the processor 10 executes the CAD program 105 (in the CAD system 200 of FIG. 1), CAD data 210 having the contents as shown in FIG. 3 is created.
[0052]
By using the CAD data as a processing target, the processor 10 executes the part material data creation program 106 (in the data converter 300 in FIG. 1), thereby creating the part material data 310 having the contents shown in FIG. The part material data 310 is stored in the part material database of the storage device 16.
[0053]
When the processor 10 executes the part material data creation program 106 (in the data conversion apparatus 300 in FIG. 1), in the recyclability evaluation system, the part base stored in the part basic information database held in the storage device 16 While referring to the data, for each part unit included in the CAD data 210, obtain the type of material (constituent material type) constituting the part and the mass of the material in the part (constituent material mass), and at least The part material data 310 for each product including the part name, the type of material constituting the part (constituent material type), and the mass of the material (constituent material mass) is created and stored in the part material database of the storage device 16 Remember.
[0054]
When creating the part material data, the unit name in the CAD data may be replaced with identification information (for example, a name indicating the disassembly level) indicating the position (level) on the hierarchical structure of the part.
[0055]
Further, when the processor 10 executes the part material data creation program 106 (in the data conversion apparatus 300 in FIG. 1), the part material data stored in the part material database held in the storage device 16 is converted into CAD data. Convert. That is, for example, for each part unit included in the part material data, information such as the type of material constituting the part (type of constituent material) and the mass of the material (constituent material mass) is omitted, and the part name or unit name When the name is replaced, the name is returned to the original CAD data, and the part name, its quantity / number, and the shape information indicating the shape of the part depending on the type of the part are included. The original CAD data 210 in the format as shown in FIG. Here, the CAD data obtained by converting the part material data can be used in the CAD system 200 as a matter of course.
[0056]
FIG. 4 shows an example of a display screen displayed on a predetermined display as the output device 14 when part material data is created based on the CAD data 210 in the recyclability evaluation system.
[0057]
In the display area R1 of the display screen shown in FIG. 4, for example, the hierarchical structure of the units constituting the product is displayed in a tree format based on the configuration information included in the CAD data. Alternatively, the shape and configuration of the product itself may be displayed in 3D format. Or you may make it display the shape and structure of a product using a tree format and 3D format together.
[0058]
For example, by selecting a desired part from the display area R1, CAD data related to the selected part is displayed in the display area R2, and the part material data corresponding to the part is stored in the storage device 16 as a part. It is read from the material database and displayed in the display area R3 as input data (used for recyclability evaluation and environmental load evaluation).
[0059]
For example, when “part A” is selected from the display area R1, the part name, quantity / number, shape, and the like of the part A are displayed in the display area R2, and the part of the part is displayed in the display area R3. A part name, a constituent material type (material name) as a kind of material constituting the part, a constituent material mass (mass) as a mass of the material, and the like are displayed. When a plurality of materials of the part are included, the material name and mass for all of them are displayed.
[0060]
In this state, when the material name or the like displayed in the display area R3 is corrected, the correction can be performed using the input device 15 such as a keyboard or a mouse, and the part material database can be updated.
[0061]
In the component selection in the region R1, the units using the same material or the same component as the selected component may be displayed in a list display or in a colored display in 3D format. Thereby, it is possible to easily grasp the material of the entire product. Further, a plurality of these same materials or same parts may be selected at the same time, displayed in the display area R2, converted into data, and displayed in R3.
[0062]
The storage device 16 holds a component basic information database used when creating the component material data 310 from the CAD data 210.
[0063]
The component basic information database stores component basic data in a format as shown in FIG. 5, for example.
[0064]
As shown in FIG. 5, the basic part data for each part includes information such as the type of material constituting the part and the mass or density of the material in the part.
[0065]
It is preferable that the mass of the material in the part is included as basic part data for each type of material. However, depending on the type of the part and the type of material, it may not be simply converted into mass. In such a case, it is preferable that the component basic data includes a density that is a mass for each type of material in the part per unit volume of the part.
[0066]
Here, for each part, a case where the mass and density for each type of material constituting the part is included in the part basic data will be described. However, the present invention is not limited to this case, and the part is configured for each part. It is only necessary that the component basic data includes data on a mass conversion factor, such as length, amount, mass per unit, and the like that can calculate the mass of each material type.
[0067]
In order to perform a recycling evaluation and an environmental load evaluation on a product, it is necessary to determine the type of material constituting the part and the mass of the material in the part for each part constituting the product.
[0068]
If the mass of each material type includes the mass for each material type in the component basic data, this mass is used as it is, or the mass is included in the CAD data. It can be calculated by multiplying the number and amount of. When the component basic data includes the respective densities for each type of material, first, the volume of the component is calculated from the shape information of the component included in the CAD data. The shape information is information representing the shape and size of the part, for example, the vertical, horizontal, height, length, and thickness of the part. By multiplying the calculated volume of the part by the density corresponding to the type of material included in the basic part data, or by multiplying the number and quantity of the part included in the CAD data, The mass for each material can be calculated for each type of material constituting the part.
[0069]
Next, the processing operation of the recyclability evaluation system (processing operation of the data converter 300 in FIG. 1) when the processor 10 executes the part material data creation program will be described with reference to the flowchart shown in FIG.
[0070]
First, the CAD data 210 is created when the processor 10 executes the CAD program 105 (step S501). When the user causes the processor 10 to execute the part material data creation program, the processor 10 accesses the component basic information database held in the storage device 16 and includes the CAD data 210 in the CAD data 210. For each component, the component basic data is searched (step S502).
[0071]
Next, based on the retrieved part basic data, the type of material constituting the part and the mass of the material are calculated for each part (step S503).
[0072]
When the retrieved component basic data includes the mass value of the material for each material type, for example, the mass is included in the CAD data. It is calculated by multiplying the number and quantity of. When the component basic data includes density values for each type of material, first, the volume of the component is calculated from the shape information of the component included in the CAD data. Then, the calculated volume of the part is multiplied by the density corresponding to the type of material included in the basic part data, and further multiplied by the number and amount of the part included in the CAD data. To do.
[0073]
In this way, information that is not included in the CAD data for each part while referring to the basic part data from the CAD data (for example, the type of material constituting the part and the material by type of material) The component material data for each part is created (step S504), and the part material data for each part is classified and classified based on the product configuration information included in the CAD data. By storing in the storage device 16 while organizing, for example, a parts material database as shown in FIG. 7 can be created (step S505).
[0074]
The part material database shown in FIG. 7 is an example of a part material database for a certain product.
[0075]
For example, this product is mainly composed of three layers in terms of its function and configuration, and these three layers are referred to herein as decomposition levels. The disassembly level consists of basic parts that are combined in manufacturing a product, a first unit (part module) that is configured by combining some of these basic parts, and some of the first units. This is the level of the hierarchical structure of parts for managing separately by combining the second units configured.
[0076]
For example, electrical / electronic components such as an IC and a wiring board are basic components, and these are combined to form, for example, a package as a first unit. Assume that two units are configured, and these second units are combined to form a finished product.
[0077]
The configuration information included in the CAD data of the product includes, for example, information on the hierarchical structure of the parts including the basic parts, the first unit, and the second unit as described above. In step S505 of FIG. 6, based on this configuration information, for example, the part material database as shown in FIG. 7 is created while counting the part material data for each part according to the hierarchical structure of the parts.
[0078]
In FIG. 7, the component (1), the component (2), and the component (3) correspond to the second unit, and are referred to as a first disassembled component here. The component (1) is composed of the component (1-1), the component (1-2), and the component (1-3), which correspond to the first unit, and is referred to as a second disassembled component here. . The component (1-3) includes a component (1-3-1) and a component (1-3-2), which correspond to basic components, and is referred to as a third disassembled component here.
[0079]
Of course, in the first disassembled part and the second disassembled part, when there are no parts to be further subdivided, there are no parts of a lower hierarchy. That is, even the first disassembled part or the second disassembled part may be a terminal part of the hierarchical structure.
[0080]
In step S504 of FIG. 6, part material data is created for a part that does not have any further parts to be subdivided (at the end of the hierarchical structure of the part).
[0081]
In FIG. 7, based on the part material data for each part located at the end of the hierarchical structure of parts created in step S504, the mass of the material calculated for each material type for each part is summed. Another mass (weight in FIG. 7) is calculated. The mass (weight) of the parts in each hierarchy is shown as the total value of the mass (weight) for each part of the parts in the lower hierarchy.
[0082]
The types of materials constituting each part are classified into a large classification and a small classification. For example, metals, plastics, etc. shown in FIG. In metal, metal 1 and metal 2 are “materials” as a small classification.
[0083]
In this way, by obtaining the part material data for all parts in the CAD data of a certain product input in step S501, the part material database corresponding to the product, for example, as shown in FIG. 7 is stored. Created in device 16.
[0084]
In the component material database shown in FIG. 7, the component names are listed in the vertical column, and the material names are listed in the horizontal row. The total mass of material contained in each part is entered in the table. In FIG. 7, the material used for the product is divided into three stages of decomposition units (decomposition levels).
[0085]
Specifically, each product (each part) is provided with information on “decomposition level” and “material classification”. “Disassembly level” is further divided into three types: “first disassembly part”, “second disassembly part”, and “third disassembly part”, and “third disassembly part” disassembles the product (or parts) separately. In this case, it is a part at the basic part level that cannot be disassembled any more, for example, a basic part level such as a screw, a spring, a key top, a decorative panel, or a wiring board. The “second disassembled component” is a component module configured by combining some of these basic parts, and the “first disassembled component” is a unit configured by combining component modules. The finished product is an assembly of a plurality of necessary part units. Therefore, the product disassembly level is “first disassembly part” in which the product is disassembled into part units, and “second disassembly part in which the part unit is disassembled into component modules. "Parts" and "third disassembled parts" that are disassembled into individual basic parts are managed separately.
[0086]
The parts at each disassembly level are registered with "part name" and "mass" for each part, and for each part located at the end of the hierarchical structure of the part, the relevant material is classified according to the type of material constituting the part. The mass of was registered and managed.
[0087]
In this way, by registering the parts that make up a product into multiple parts in the parts material database, it is possible to obtain important information for considering the recyclable mass or recyclability from the viewpoint of decomposition level. Is possible. In addition, it is possible to provide information on the reduction of materials used in products by calculating the total mass of products or parts.
[0088]
In the recyclability evaluation stage, processing is performed based on the contents of the part material database shown in FIG. 7. The term “part” used in the description of this process is the same as the part material database. For example, it is assumed that the part belongs to one of the first disassembled part, the second disassembled part, and the third disassembled part.
[0089]
The content of the data held in the component material database is displayed on a display screen as shown in FIG. 4, for example, or can be corrected by the user based on the display content (step S506).
[0090]
Next, the description returns to FIG.
[0091]
In FIG. 2, an input / output processing program 101 is one of programs stored in the memory 100. The input code is acquired by operating the keyboard, the display information is output to the display, and the input / output control of data with respect to the input / output interface. It consists of a function program that executes print output control to the printer.
[0092]
The database management program 102 is also one of the programs that the memory 100 has, and is configured by a function program that manages the database constructed in the storage device 16.
[0093]
The recyclability evaluation program 103 is also one of the programs of the memory 100, and the recyclability evaluation program 103 performs a recyclability evaluation process based on information given via these 101 and 102. It is.
[0094]
The evaluation result output processing program 104 is also one of the programs of the memory 100, and is used to arrange the display format for outputting the evaluation results and the like by the recyclability evaluation program 103.
[0095]
The storage device 16 is for holding various data files and the like, and also holds various databases including a database (DB) 160 of recyclability evaluation information used in the system of the present invention. The database 160 of recyclability evaluation information constructed and held in the storage device 16 is, for example, information on metal mixture admissibility, which is information on availability regarding a mixture of metals, and information on availability regarding a mixture of plastics. "Mixing tolerance" by material such as plastic mixing tolerance information, "Processing classification", "Basic unit", "Impurity content (combination and blending ratio)" by mixing material, "Easy removal by mixing material" The database consists of individual databases such as “compatibility”, “compatibility” for each mixed material, and “marketability”, and is a flexible database that can add, change, and delete information.
[0096]
The environmental load basic unit database stores, for example, the environmental load basic units of raw materials created based on the Input-Output Law or obtained from literature. When the recycling unit information in the recyclability information database is insufficient, enter the amount of raw materials such as energy input to the recycling process and multiply the raw material unit stored in the environmental load unit database The unit for recycling is created by accumulating.
[0097]
The recyclability evaluation program 103 includes a processing step for creating part material data from CAD data, a processing step for inputting evaluation condition settings, and a processing for evaluating recyclability using the information in the recyclability information DB 160. And a process step for shifting to a process for displaying an evaluation result.
[0098]
<Recyclability evaluation procedure>
The recycle evaluation system according to the present embodiment is a database (recycling) that summarizes the admixture of materials in order to be able to support the selection of parts and materials for manufacturing to improve the recyclability of products. Recyclability evaluation by referring to the information in the recyclability information DB for the mixture composition allowed for recycling from the material mixture information on the input evaluation target product or part, etc. Evaluation is made by processing.
[0099]
Then, the process for realizing the evaluation is performed according to the procedure shown in FIG. The overall flow of recyclability evaluation in this embodiment will be described with reference to the recyclability evaluation flow as the basic procedure shown in FIG.
[0100]
[Processing step S1] (Creation of parts material database)
First, the processor 10 executes the recyclability evaluation program 103. As a result, the recyclability evaluation program 103 executes processing for creating part material data from CAD data, as described above, for example, Then, a parts material database as shown in FIG. 7 is created.
[0101]
[Processing step S2] (Evaluation condition setting (input))
When the part material data creation process ends, the process in the recyclability evaluation program 103 executed next by the processor 10 changes to a request for setting the evaluation condition. Here, the user sets the evaluation condition according to the request. For example, the user inputs the evaluation condition by operating the input device 15. This input information is taken in by the input / output processing program 101.
[0102]
The contents of the evaluation conditions are set, for example, in the range to be included in recycling, such as “whether or not plastic heat recovery is included” or “mixing tolerance level in the judgment of mixing tolerance”. To do. When this setting is completed, the processor 10 next performs a mixing admissibility determination.
[0103]
[Processing step S3 (Processing S31)] (Mixing admissibility determination)
When the evaluation condition setting is completed, the processing in the recyclability evaluation program 103 executed by the processor 10 next moves to the mixing admissibility determination processing.
[0104]
The process for determining the mixability is the process of step S3. In this process, with reference to the metal mixability database and the plastic mixability database in the recyclability information DB 160, the process is included for each component unit to be evaluated. The mixing admissibility of the material to be processed is determined (processing S31).
[0105]
[Processing Step S3 (Processing S32)] (Processing Content Determination)
When the determination of the admissibility of the materials included in each component unit to be evaluated is completed, the processing in the recyclability evaluation program 103 executed by the processor 10 next moves to processing content determination processing. This process is the process of S32 in process step S3, and in this process, which of a plurality of modeled disposal / recycling contents (modeled methods of disposal / recycling of a plurality of types) is applied. This process is performed to select which process is applied for each component unit to be evaluated (see FIG. 10).
[0106]
[Process Step S3 (Process S33)] (Calculate Recyclable Mass and Recyclability Rate)
When the disposal / recycling content to be applied (the disposal / recycling processing method to be applied) is selected, the processing in the recyclability evaluation program 103 executed by the processor 10 next is the selected disposal / recycling content (the selected disposal / recycling method). The process proceeds to the calculation of the amount (recyclable mass) that can be used for the processing for the recycling processing method) and the ratio (recyclable rate). This process is a process of process step S3 (process S33). In this process, the recovery yield rate and the like are extracted from the disposal / recycling process classification / base unit database in the recyclability information DB 160 for each part material to be evaluated and applied. Accumulate for each disposal / recycling method and for each part, and calculate recyclable mass and recyclable rate. Furthermore, the recyclable mass for each part is integrated to calculate the recyclable mass and recyclability rate of the entire product.
[0107]
[Processing step S4] (Evaluation result output display)
When this calculation processing is completed, the processing in the recyclability evaluation program 103 executed by the processor 10 next moves to display processing, and the evaluation result by the recyclability evaluation program 103 is passed to the evaluation result output processing program 104 for output. Process to arrange the display format. The evaluation result output processing program 104 arranges the processing method, recyclable mass, and recyclable rate selected / calculated by the recyclability evaluation program 103 in a format and passes it to the input / output processing program 101. The input / output processing program 101 outputs this. Processing is performed to display on the display as the device 14.
[0108]
As a result, based on the input conditions, the display shows the disposal method for the collected items to be evaluated, the calculated recyclable mass applicable to the disposal method, and information on the recyclability rate. The user can know the disposal method, the recyclable mass, and the recyclable rate for the mixture (recovered product) to be evaluated. Note that the output display may not be all of them but only a part of them if necessary.
[0109]
As described above, in the parts material database, when the component parts are composed of smaller parts, the parts are divided into small parts. And the total mass of the material in the component are stored.
[0110]
In this way, the component material is divided into multiple stages, and the component material data is stored in the component material database, so it is important to obtain information that is important for considering the recyclable mass or recyclability from the viewpoint of decomposition level. Is possible.
[0111]
As a result, in product development, it becomes possible to select component materials that can be manufactured with the aim of improving the product for recyclability.
[0112]
In the evaluation condition setting input (processing step S2), the disassembly level setting that assumes which disassembly level is disassembled (disassembled) among the component parts, and the output level setting that sets items to be displayed on the output screen Etc. may be performed.
[0113]
As described with reference to FIG. 7, the decomposition level (decomposition depth) may correspond to, for example, a hierarchical structure of component configurations.
[0114]
When the disassembly level is set, the weight can be summed up for each material of the small parts united in accordance with the disassembly level, and the recyclability evaluation can be performed on the disassembly part basis. At this time, the material table as shown in FIG. 7 in the parts material database may be reconstructed in units of disassembled parts and further in the order of disassembly. As a result, information on the type and number of materials contained in the disassembled parts and the depth level of the disassembly can be added to the recyclability evaluation and output.
[0115]
In the calculation of the recyclability rate (process S34 in process step S3), the evaluations performed for each determination element in process S31 in process step S3 are scored and integrated, and are scored and displayed as a recyclability index. It is also possible.
[0116]
Further, in the output display (processing step S4), improvement points may be suggested and displayed as additional information in the recyclability evaluation. These include, for example, a display of parts or materials with a low recycle rate, a non-mixable part material and a reason display. In addition, it is possible to output and display information on the type and number of materials contained in a small part (disassembled part) integrated in accordance with the disassembly level, the disassembly depth level, and the like.
[0117]
The above is the evaluation of recyclability, that is, how much can be finally used for what kind of disposal (disposal, various recycling treatments), and how much of the recovered items such as products and materials, etc. We explained the system that performs the recyclability evaluation process as a basic procedure that can be evaluated, but if you take this one step further and change the decomposition level, the applicable treatment method will change and the disposal method ( An example of how much amount can be used for disposal and various recycling treatments, and how much it can be evaluated as a percentage, and an evaluation system useful for design support including disassembly can be realized. Next, a description will be given.
[0118]
<Another example of recyclability evaluation procedure>
An example of the evaluation process in this case is shown in FIG. FIG. 9 shows an example of a recyclability evaluation procedure in which decomposition level information, improvement point information, and the like are added to the basic procedure shown in FIG.
[0119]
[Processing step S1] (part material database creation)
First, as in FIG. 8, the processor 10 executes the recyclability evaluation program 103. As a result, the recyclability evaluation program 103 creates the part material data from the CAD data as described above (see FIG. 6). Will be carried out.
[0120]
[Processing step S2] (Evaluation condition setting (input))
Next, the processing in the recyclability evaluation program 103 executed by the processor 10 is changed to a request for setting an evaluation condition. Here, the user sets the evaluation condition according to the request. For example, the evaluator operates the input device 15 to input the evaluation condition setting. This input information is taken in by the input / output processing program 101.
[0121]
The setting contents of the evaluation conditions are a decomposition level, a recycling level, an output level, etc., and the recycling level is, for example, a range to be included in recycling, for example, “whether to include heat recovery of plastic” or “mixing allowance” “Mixing tolerance level in sex determination”, etc. When these settings are completed, the processor 10 next performs a process for evaluating recyclability.
[0122]
[Processing step S3 (Processing S301)] (Calculation of dismantling index)
When the evaluation condition setting is completed, the processing in the recyclability evaluation program 103 executed by the processor 10 next moves to the dismantling index calculation processing.
[0123]
The dismantling index calculation process is the process of S301 in process step S3. In this process, the dismantling index is calculated using the recyclability information DB. When this is finished, the mixing admissibility determination is performed.
[0124]
[Processing step S3 (Processing S302)] (Mixing admissibility determination)
The process for determining the mixing allowance is the process of S301 in process step S3, and using the metal mixing allowance database and the plastic mixing allowance database, the mixing allowance of the material included for each component unit to be evaluated is determined. To do. When this is finished, the recycling target is determined next.
[0125]
[Processing step S3 (Processing S303)] (recycling target determination)
Recycling target determination processing is the processing of S303 in processing step S3. What is the recycling target material, whether impurities are easily removed, what is compatibility, and what is marketability? Judgment is made with reference to information in the information database. When this is done, the recycling process assumption is made.
[0126]
[Processing step S3 (Processing S304)] (recycling process assumption)
The recycle process assumption is the process of S304 in process step S3, and it is assumed by what process process the recycle target is processed. Here, the parts to be evaluated are determined by determining which to apply from the multiple types of disposal / recycling content modeled (methods of multiple types of disposal / recycling modeled) For each unit, select which processing method to apply. When this is complete, the recycled mass is calculated.
[0127]
[Processing Step S3 (Processing S305, S306)] (recycling mass calculation, recycling rate calculation)
When the disposal / recycling content to be applied (the disposal / recycling processing method to be applied) is selected, the processing in the recyclability evaluation program 103 executed by the processor 10 next proceeds to processing of recycling mass calculation and recycling rate calculation. Recycling mass calculation processing is processing step S3 (processing S305), and recycling rate calculation is processing of S306. In these processings, each part material to be evaluated is collected from the disposal / recycling processing classification / basic unit database. Yield rate, etc. are extracted and integrated for each applicable disposal / recycling method and for each part, and the recyclable mass and recyclable rate are calculated. Furthermore, the recyclable mass for each part is integrated to calculate the recyclable mass and recyclability rate of the entire product. When this is done, the next cost index is calculated.
[0128]
[Processing step S3 (Processing S307)] (Cost index calculation)
The cost index calculation is the process of S307 in the process step S3, and an index of the cost for recycling the recycling object is obtained. For the cost index, the processing unit price for each processing method, the unit price for the recovered product, etc. are extracted from the disposal / recycling process classification and basic unit database, and the cost index is calculated for each applicable disposal / recycling method and for each part. To do. When this is finished, the process proceeds to an improvement proposal display process.
[0129]
[Processing step S3 (Processing S308)] Improvement proposal display
Based on the above evaluation results of recyclability, the factors that inhibit the recyclability of the product are analyzed, and the improvement measures corresponding to the obstacles obtained as a result of the analysis are created and displayed. In addition, based on the displayed improvement measures, the evaluation conditions and part material data used for the above recyclability evaluation are temporarily changed, and the recycling is performed again based on the changed evaluation conditions / part material data. The evaluation of the improvement effect is made by evaluating the sex.
[0130]
[Processing step S4]
The processing in the recyclability evaluation program 103 executed by the processor 10 shifts to display processing, and the result of evaluation by the recyclability evaluation program 103 is passed to the evaluation result output processing program 104 to prepare the display format for output. Let The evaluation result output processing program 104 is a processing method selected and calculated by the recyclability evaluation program 103, recyclable mass, recyclable rate, parts disassembly target / non-target, recyclable / impossible, cost index, improvement proposal (low recycling) I / O processing by arranging the format of information such as rate parts (which are low recyclable parts, disassembly required parts (which require disassembly work), non-mixable parts (which cannot be mixed)) The program is passed to the program 101, and the input / output processing program 101 processes it to be displayed on the display as the output device 14.
[0131]
As a result, the display shows various analysis result information, including the selected treatment method for the object to be recycled and the calculated recyclable mass, recyclability rate, etc. to which the treatment method is applied. It is arranged and output and displayed as an evaluation result, and the user can know the recycling evaluation result for the object to be recycled.
[0132]
In particular, in this example, it is possible to evaluate by changing the decomposition level in various ways, so it is possible to understand the changes in the evaluation contents due to the change in the decomposition level, so it is effective in supporting optimal design focusing on recycling during product development. .
[0133]
Based on the recyclability evaluation result according to the present invention, the user makes improvements for improving the recyclability of the product by using the disassembling evaluation tool to improve the resolvability and using the part material information from the parts information database.
[0134]
That is, if the displayed evaluation result meets the target, the evaluation analysis is terminated in order to adopt the evaluation result in the recycling plan (step S11 in FIG. 9). If it does not meet the target, review the parts materials to be used for manufacturing the product in consideration of recycling (step S12 in FIG. 9), further review the disassembly (step S13 in FIG. 9), and review these. It is possible to select parts materials for manufacturing that will ultimately improve the recyclability of the product by repeating the process of updating the parts material database with the parts that have been determined and the materials that make up the parts. become able to.
[0135]
The system according to the present embodiment determines the value as a used material necessary for recycling the collected product to be evaluated (judgment of material mixing tolerance), and the judgment of the content of the recycling process, that is, the collection of products and materials. What kind of disposal (disposal, various recycling processes) is finally possible for a product is evaluated. A specific example of the evaluation process will be described next.
[0136]
[Details of Mixing Allowability Determination S302 and Recycling Process Content Determination in Processing Step S3]
FIG. 10 is a flowchart showing in more detail the mixing admissibility determination of S302 in the processing step of the recyclability evaluation of FIG. In the mixing admissibility determination S302, the admissibility is determined including the determination of the utility value of the mixed material. However, here, an example is shown in which it is possible to go one step further to determine the final recycling process content. .
[0137]
Contents of disposal / recycling based on information on the mixture of the materials that make up the collected product (product or part) to be evaluated (information on all types of materials that will be mixed when different types of materials are mixed) It is an example of the judgment flow which determines.
[0138]
When products or parts made of metal, plastic, glass, or other dissimilar materials are collected, and the collected items are discarded and recycled without being separated by dismantling, they are not usually left in their original form. Material recycling or heat recovery is performed through mechanical crushing and sorting, which is once crushed and separated.
[0139]
That is, it is separated into materials that can be sorted by mechanical crushing and sorting and other residues. The recycling rate can be added with data such as the purity of the collected product by the basic unit database illustrated in FIG. 17 together with the value in which the sorting yield rate is taken into consideration.
[0140]
When collected materials do not contain different materials, or when dissimilar materials are separated and then processed, “plastics”, “metals”, “glasses”, “ceramics / ceramics” The admixture of similar materials is evaluated in an arbitrary material classification such as “,” “medicine”, “wood”, “animal / vegetable / liquid”.
[0141]
The processing will be described according to the flow of FIG. Products and parts that use metals, plastics, glass, and other dissimilar materials will be discarded and recycled unless the parts are reused as they are (reuse). .
[0142]
Therefore, the recovered product is made into a material by this pulverization process, but the materialized material is a mixed material of the same kind of material and a mixed material of a different kind of material. Later, recyclability will be evaluated.
[0143]
Specifically, it is first determined from the part material data for each part stored in the part material database whether the material to be recycled is a mixed material of different materials (step S101). As a result, if the material is a mixed material of different materials, it is selected as mechanical crushing (step S118), and the material cycle and heat recovery are selected for disposal (step S119). In other words, after the mechanical crushing and sorting process, it is determined that the single component separated by sorting is reused by the material cycle, and the residue is recovered by incineration.
[0144]
On the other hand, as a result of the determination in step S101, the process proceeds as follows depending on whether the object is plastic, metal, glass, etc., if the different materials are not mixed.
[0145]
If the target is plastic, the processing after step S102 is performed. That is, it is determined from the amount of impurities in the mixed material (determined by referring to the information in the impurity amount database) whether or not the required level is satisfied (OK / NG) (step S103). If the level is satisfied, it is determined to be used as a material recycling material (closed) (step S107). That is, it is determined that closed-type material recycling that can be reused as a raw material for the same application is possible only by re-molding in the manufacturer without performing processing such as refining by an external processor.
[0146]
On the other hand, if the amount of impurities in the mixed material is less than the required level (if it is NG), the ease of removal is judged by referring to the information in the prepared ease database (OK / NG) ( Step S104). As a result, if the ease of removal is good (if OK), it is determined that the material is used as a material recycling material (open) (step S108). That is, it is determined that open-type material recycling that requires purification by an external processor is possible. In this case, the recovered product is used for the same application (horizontal) and another application (cascade).
[0147]
As a result of the determination of ease of removal in step S104, if the ease of removal is not good (if NG), the compatibility is determined with reference to the information in the compatibility database prepared (step S105), If the compatibility is good (if OK), it is determined to be used as a material recycling material (open) (step S108). In this case, since the composition changes with the material used for the product, it is used for another application (cascade) as an open type via an outside contractor.
[0148]
However, if the compatibility is not good as a result of the determination in step S105 (if NG), then marketability is determined (step S106).
[0149]
As a result, if the blend polymer has marketability (if OK), it is determined to be used as a material recycling material (open) (step S108). Also in this case, since the composition changes with the material used for the product, it is used for another application (cascade) as an open type via an external supplier.
[0150]
However, as a result of the marketability determination in step S106, if there is no marketability (if NG), it is decided to dispose of heat by disposable (material recycling one-way) and incineration (step S109).
[0151]
Further, as a result of the determination in step S101, if the target is a metal, the processing after step S110 is performed. That is, judging from the amount of impurities in the mixed material, it is determined whether or not the required level is satisfied (OK / NG) (step S111). Is determined to be used (step S107). In other words, it is determined that closed-type material recycling that can be reused as a raw material for the same application is possible only by re-molding within the manufacturer without performing refining or the like by an external processor.
[0152]
On the other hand, if the amount of impurities in the mixed material is less than the required level (if it is NG), the ease of removal is judged by referring to the information in the prepared ease database (OK / NG) ( Step S112). As a result, if the ease of removal is good (if OK), it is determined that the material is used as a material recycling material (open) (step S116). That is, it is determined that open-type material recycling that requires refining by an external processor is possible. In this case, the recovered product is used for the same application (horizontal) and another application (cascade).
[0153]
As a result of the determination of ease of removal in step S112, if the ease of removal is not good (if NG), the compatibility is determined by referring to the information in the compatibility database prepared (step S113), If the compatibility is good (if OK), it is determined to be used as a material recycling material (open) (step S116). In this case, since the composition changes with the material used for the product, it is used for another application (cascade) as an open type via an outside contractor.
[0154]
However, if the compatibility is not good as a result of the determination in step S113 (if NG), then the marketability is determined by referring to information in the prepared marketability database. (Step S114). In the marketability database, for example, judgment criteria reflecting demands and valuable information as alloys are set.
[0155]
As a result, if it has marketability (if OK), it is determined that it is used as a material recycling material (open) (step S116). Also in this case, since the composition changes with the material used for the product, it is used for another application (cascade) as an open type via an external supplier.
[0156]
However, if the marketability is not determined as a result of the marketability determination in step S114 (if NG), it is determined to be discarded (landfill) (step S117).
[0157]
Similarly, even if the mixed material is glass, etc., whether the material can be used as an open, closed, or discarded, heat recovery by judging the amount of impurities, ease of removal, compatibility, marketability, etc. Determine the final usage pattern.
[0158]
Thus, it is possible to determine a disposal method such as how the target mixed material can be recycled or discarded.
[0159]
Note that the individual determination elements such as the impurity tolerance, the ease of removal, the compatibility, and the marketability shown in the flow of FIG. 10 are the individual determination elements illustrated in FIGS. 11 to 14 corresponding to the respective determination elements. The determination is performed using a database or a mixture admissibility database for each material in which individual determination elements illustrated in FIGS. 15 and 16 are integrated.
[0160]
These determination elements are not limited to the example shown in FIG. 10, and various determination elements can be incorporated. Further, the determination order is not limited to the example of FIG. 10, and determination work can be performed in an arbitrary order. Furthermore, the determination result should be updated as needed in response to changes that occur over time, such as technological innovation and market changes, and is not limited to the example of FIG. Based on this flow, the material to be recycled and the contents of disposal / recycle reflecting the mixed state of the evaluation target product or parts are determined. Based on this determination, the basic unit database illustrated in FIG. 17 makes it possible to assume a recyclability rate, a recycle index, a recycle cost, and the like.
[0161]
As described above, in the above system, various databases constituting each element of the recyclability evaluation database are prepared, and the recyclability of the material to be evaluated is evaluated based on the information provided by these databases. A few words about the individual databases used.
[0162]
[Individual database]
FIGS. 11 to 14 show examples of detailed databases along the flow of FIG. Among these, FIG. 11 is an example of a plastic impurity content database, and FIG. 12 is an example of a plastic removal ease database. FIG. 13 is an example of a plastic compatibility database, and FIG. 14 is an example of a plastic marketability database.
[0163]
As shown in FIG. 11, in the plastic impurity content database, information on resin combinations and blending ratios (weight ratios) is held as a database. Further, as shown in FIG. 12, the database for the ease of removal of mixed plastics includes a discrimination / separation technology database, which has an “automatic sorting technology” for each resin combination. ) ”,“ There is automatic discrimination technology (Δ) ”, or“ Difficult to sort (x) ”as information, and the plastic compatibility database shows combinations of various resins as shown in FIG. Separately, whether the combination is “compatible polymer blend (s)”, “polymer alloying with compatibilizer is possible (c)”, “no compatibilization information (n)”, etc. Information is stored as a database.
[0164]
In addition, as shown in FIG. 14, the database summarizing the marketability of the mixed plastic material is “commercially available products with the same blend composition (O)” for each combination of resins. Information such as “a possible combination (Δ)” or “a combination with poor marketability (×)” is stored as a database.
[0165]
11 to 14 show examples of only plastics as the target material, but it goes without saying that databases are prepared for metals, glasses, and other material classifications in the same manner. Nor.
[0166]
Elements other than those shown in the flow of FIG. 10 can be added as determination elements for determining the admixability of materials. In this case, a database corresponding to each element is prepared. Moreover, it is not necessary to use all the determination elements of the flow of FIG. 10, and it is possible to determine the selected element or elements of these determination elements based on the detailed database. It is also possible to integrate these plural determination elements and use them as a mixture admissibility database.
[0167]
FIGS. 15 and 16 are examples of plastics and metals in such an integrated mixing tolerance database.
[0168]
As shown in Fig. 15, the database that summarizes the plastics admissibility for material recycling shows that there is "recycled potential demand (A)" depending on the combination of various resins. Is a combination that may be acceptable (B), or is a combination that can be found to be mixed by technology development in the future (C). Information (D) "that needs to be executed is stored as a database.
[0169]
As shown in Fig. 16, the database that summarizes the metal mixing allowance for material recycling shows whether there is "recycled potential demand (A)" for each combination of metals, or " Is a combination that may be acceptable (B), or is a combination that can be found to be mixed by technology development in the future (C). Information (D) "that needs to be executed is stored as a database.
[0170]
In the database examples of FIGS. 11 to 14 described above, the type names of the first component plastics are listed in the vertical column, and the type names of the second component plastics are listed in the horizontal row. The order of enumeration is not particularly limited, and the types to be enumerated need not be completely the same for the plastics of the first component and the second component.
[0171]
However, from the viewpoint of easy understanding, in the examples of FIGS. 11 to 14, the same types as the plastics of the first component and the second component are taken up as items and listed in the same order. In the table, at the intersection of the first component plastic column and the second component plastic row, the individual judgment of impurity tolerance, ease of removal, compatibility, marketability, etc. for each of the two plastics The mixing tolerance evaluation level for each element is stored.
[0172]
In FIG. 11, since the plastic of the first component is handled as a single component, the impurity concentration allowed when the second component is mixed as an impurity is indicated by weight% with respect to the first component. When the amount is less than the allowable amount, it is determined as “mixing allowable”.
[0173]
In FIG. 12, “a combination in which an automatic sorting technique exists” / “although there is an automatic discrimination technique, a sorting technique may or may not be possible depending on conditions such as a shape” / “difficult to sort”. An example is shown in which “combination” is divided into three stages. According to the evaluator's setting, the highest level or the second level among the three levels is determined as “mixing acceptable”.
[0174]
In FIG. 13, two or more stages of “compatibility evaluation level is compatible” / “compatibility evaluation level is incompatible” may be divided into any number of stages as required. In FIG. 13, “compatible polymer blend” / “incompatible polymer blend can be compatibilized by adding a compatibilizer” / “combination without compatibilization case” is divided into three stages. An example is shown. According to the evaluator's setting, the highest level of the three levels or the level of the second level is determined as “mixing acceptable”.
[0175]
FIG. 14 shows an example divided into three stages of “polymer blend composition marketed as a product” / “combination with marketability” / “combination with low marketability”. Depending on the evaluator's setting, the upper one or two levels of the three levels are determined to be allowed to be mixed.
[0176]
Examples of the classification of plastics when creating the database include various thermoplastic resins and thermosetting resins.
These include, for example, polyethylene (PE), polypropylene (PP), polystyrene (PS), polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polycarbonate (PC), acrylonitrile-butadiene-styrene copolymer (ABS), acrylonitrile. -Styrene copolymer (AS), polyamide (PA), polyvinyl chloride (PVC), polyvinylidene fluoride (PVDF), polymethyl methacrylate (PMMA), polyvinyl alcohol (PVA), polyacetal, petroleum resin, polyphenylene ether (PPE) ), Urethane elastomer, foamed urethane, epoxy resin, urea resin, phenolic resin, unsaturated polyester, silicon resin, alkyd resin, melamine resin, synthetic rubber, natural rubber, thermoplastic resin in general, thermosetting resin in general, etc. .
[0177]
In addition, brand names and grades of resin products, additives that become integral when the resin is molded, such as brominated, phosphorous, and inorganic flame retardants, dioctyl phthalate (DOP), diethylhexyl phthalate (DEHP), etc. Reinforced fibers such as plasticizers, colorants, inorganic fillers such as bulk mold resin (BMC) and sheet mold resin (SMC), organic fillers such as wood chips, fiber reinforced plastic (FRP), printed circuit boards, halogen-free substrates It is also effective in material recycling to classify by type of mixture, type and grade.
[0178]
As a classification of metals, for example, iron, copper, aluminum, nickel, chromium, zinc, lead, tin, cobalt, manganese, molybdenum, titanium, silicon, magnesium, arsenic, bismuth, cadmium, antimony, lithium, etc. as metal elements Is mentioned. Furthermore, it is also effective to classify the material as an alloy as a material product or a material whose composition is adjusted. These include, for example, carbon tool steel, chrome-molybdenum steel, SUS304, SUS316, zinc iron plate, plated steel plate, coated steel plate, H2 steel, brass, bronze, beryllium copper, magne alloy, titanium alloy, tin lead solder, tin silver solder These are tin-zinc-based solders and the like, which can be further classified in detail according to the composition ratio. Further, it is possible to classify by shape such as plate, foil, die-cast, etc., and manufacturing method.
[0179]
Also in these other materials, for example, glass is classified by coloring such as colorless, green, brown, etc., classification by components such as lead glass, heat-resistant glass, etc., and paper and fibers are also pulp, plywood, wood Evaluation of mixing tolerance is performed using chips, corrugated cardboard, Western paper / Japanese paper in general, surface-coated paper, and the like.
[0180]
In order to compile the plastic mixing allowance database of FIG. 15, the evaluation tool design is made according to the contents to be evaluated from among a plurality of databases divided into two or more stages as illustrated in FIGS. 11 to 14. A mixing tolerance level is set by a person or a user, and a mixing tolerance database is created.
[0181]
For example, the evaluation by two detailed databases of the detailed database summarized by the compatibility of the plastic shown in FIG. 13 and the detailed database summarized by the marketability of the polymer blend shown in FIG. 14 are combined into one. A mixed admissibility database can be created.
[0182]
The mixed admissibility evaluation level in the database is at least two levels of “acceptable / non-acceptable”, and may be divided into any number of levels as necessary. If two or more types of plastic are included in the product or part that is subject to recycling evaluation, the database is divided into two or more stages as a database, and mixing is allowed according to the user's definition according to the content to be evaluated. Select the category to be For example, the blending admissibility is ranked in five stages, and the upper two stages are output as blending allowances.
[0183]
In this example, based on the compatibility tolerance database created from the viewpoint of compatibility and marketability in FIGS. 13 and 14, it is determined that mixing is possible for a combination of compatible polymer blends or a commercially available polymer blend that is already commercially available. In addition, it is determined that mixing is not possible for a category that is not selected as mixing permission.
[0184]
FIG. 16 is an example of a database summarizing the mixing admissibility of metals. As in the case of plastics, the metal mixture admissibility database also lists metal types in columns and rows, and stores the mix admissibility evaluation level in the intersections. Here, “a combination that can be separated and removed by refining the mixed metal” / “a combination that is difficult to separate but has a low accumulation level as an impurity and does not require urgent measures” / “a combination that is difficult to separate and does not require an emergency measure” An example of a database compiled from the viewpoint of ease of removal is shown in a total of three stages of “combination with high accumulation and requiring urgent measures”.
[0185]
In addition, mixing is permitted based on a detailed database based on the compatibility between metals, a detailed database that summarizes marketability such as compositions that are commercially available as alloys, and a detailed database that summarizes separability by means other than refining. A database that summarizes gender can be created.
[0186]
By performing the processing according to the flow of FIG. 8 using these databases, the required recycling content and the calculated recyclable rate value can be used for the environmental load evaluation of the product. That is, in order to give the amount of the recycled product and the content of the processing among the used products necessary for the evaluation of the environmental load of the product in the product life cycle, and “the basic unit corresponding to these”, the present invention It is possible to use the recyclability rate derived based on the mixing information of materials contained in products or parts and the processing contents thereof.
[0187]
FIG. 17 shows an example of a basic unit database for each assumed disposal / recycling classification.
[0188]
Necessary basic unit data is extracted according to the processing classification assumed in the disposal / recycling content determination flow shown in FIG. As shown in FIG. 17, the basic unit items include, for example, “recovery yield rate”, “process return rate”, “recycling rate”, “recycling index”, “disposal or recycling process running” as an evaluation of recyclability. Costs, disposal / recycling equipment costs, “sale or delivery prices for processed products” and other environmental impact assessments include “energy”, “CO ₂ ”(Carbon dioxide),“ NOx ”(nitrogen oxide),“ SOx ”(sulfur oxide),“ COD ”(Chemical Oxygen Demand),“ BOD ”(Biochemical Oxygen Demand: biochemical) Emissions requirement unit, etc. Also, it may be the input amount of items such as electric power, fuel, chemicals, etc. that are input in each process as the original data for calculating these emission intensity units. By extracting the necessary basic unit from this basic unit database, it becomes possible to perform recyclability evaluation and environmental load evaluation.
[0189]
[Determination of disposal method]
Next, disposal will be described.
[0190]
This system can determine the disposal method for evaluating the environmental load in the life cycle of products, etc., but in this determination, a plurality of disposal processing classification models and the distribution set for each classification model are determined. The user arbitrarily selects a classification suitable for the evaluation target from the database having the ratio.
[0191]
FIG. 19 shows an environmental load evaluation procedure in the disposal process. The environmental impact assessment of the disposal process is performed in the following procedure.
[0192]
[Step S141] (Creation of parts material database)
First, the processor 10 executes the recyclability evaluation program 103. As a result, the recyclability evaluation program 103 executes processing for creating part material data from CAD data, as described above, for example, As shown in FIG. 7, a part material database for a certain product (in this case, corresponding to a used product to be evaluated) is created.
[0193]
[Step S142] (Evaluation condition setting (input))
Next, evaluation conditions are set. The discard processing flow is based on a general modeled flow, and is reset only when changes are made. For example, a modeled disposal / recycling process flow as disclosed in JP-A-10-57936 is used. Further, considering the material composition of the used product or the used product excluding the recycled material, the waste classification is selected from the waste classification information database. This selection is performed based on, for example, classification based on the distribution ratio database of contents as shown in FIG.
[0194]
[Step S143] (Waste treatment process load evaluation)
Distribution ratio information and processing unit information are obtained from the waste classification information database. Furthermore, the value of the environmental load is calculated by multiplying the waste product mass by the processing unit and accumulating in accordance with the distribution ratio. For example, the calculation is based on the distribution ratio information by the distribution ratio database in FIG. 18 and the processing unit information by the unit database in FIG.
[0195]
[Step S144] (Evaluation result output display)
Output and display the calculated environmental load value.
[0196]
In the evaluation device, the above-described steps S141 and S142 are performed by input from the input device 15, and the processing of S144 is performed on the output device 14. Further, the processing in step S143 is performed inside the evaluation apparatus (processing by the environmental load evaluation program 107 executed by the processor 10 constituting the evaluation apparatus).
[0197]
FIG. 18 is an example of a distribution ratio database for determining a distribution ratio in the processing flow of the modeled disposal / recycling process.
[0198]
In FIG. 18, the first column is “Category Rank 1”, the entire waste in Japan, the second column is “Category Rank 2,” industrial waste and general waste classified as Japanese waste, the third column Is classified as “classification rank 3”, classified according to the contents of intermediate treatment mainly for industrial waste, classification mainly for dehydration, classification mainly for incineration, and other classification mainly for crushing, and Municipal wastes classified by municipality, business, and 4th column are classified as “Classification Rank 4”, and industrial waste and general waste classified according to the primary intermediate treatment classification Waste classification is listed as an item.
[0199]
In the first row of the database, distribution ratio items are listed for each process for which the distribution ratio should be determined according to the modeled disposal / recycling process flow. As the contents, for example, among the used products, “the distribution ratio in the process that is recycled by the intermediate process”, “the distribution ratio of the amount that is incinerated and the landfill that is not recycled”, “Distribution ratio of the amount to be landfilled as incineration residue out of the amount to be incinerated”. In each row, the value of the distribution ratio for each process is stored as a representative value in the classification item at each classification rank.
[0200]
As a feature of the present invention, in particular, there is provided “classification rank 3” in which waste classification is classified and integrated for several types according to the viewpoint of the contents of intermediate processing.
[0201]
In order to easily evaluate the environmental impact, the processing content of the product is generalized by representing a specific flow, and in order to evaluate using the basic unit and distribution ratio based on the statistical data prepared in advance, statistical data The key is how to organize and utilize That is, in this system, the evaluation is performed along the modeled process flow, but the information necessary for the evaluation is obtained from statistical data collected by the process flow that does not completely match the modeled process flow. Become.
[0202]
For example, for example, the waste classification is statistically grouped into three classifications: a recycling amount, a reduction processing amount, and a landfill disposal amount. At this time, the specific content of the weight reduction process is not clear. On the other hand, in order to evaluate the environmental impact, this system does not take into account the basic unit that should be used for the calculation, depending on the processing content such as whether the weight reduction process is an incineration process or a dehydration process. For example, if all are regarded as incineration disposal, it causes a large error in the evaluation result.
[0203]
In response to this problem, it was clarified that the contents of evaluation are greatly improved by representing for each waste classification what the main intermediate treatment is as a classification viewpoint of the waste classification. In the classification from the viewpoint of intermediate treatment, it is necessary to set the classification by carefully examining the magnitude of environmental loads such as energy input and carbon dioxide emissions.
[0204]
In classification rank 3 in FIG. 18, an example in which classification is performed by three types of “dehydration” / “incineration” / “crushing / others” as a classification by main intermediate processing is shown. Not only this but the classification by arbitrary contents is possible. For example, “drying”, “washing”, “compression”, “sorting”, “detoxification”, “neutralization”, “chemical treatment”, “composting”, “fuelization” reflecting further details of intermediate processing ", Etc. In addition to classification based on intermediate processing, classification based on a processing handling route or the like is also possible. In the classification of general waste, it can be classified into the details of the intermediate treatment.
[0205]
In FIG. 18, classification rank 3 is an example of classification by emission source, but general waste can also be classified by intermediate processing such as “incineration” / “crushing” / “composting” / “others”. Examples of classification rank 4 in this case are moss, paper, plastics for incineration, glass bottles for crushing, cans, electrical products, furniture, vegetation for composting, batteries, fluorescent lights, etc. is there.
[0206]
In addition, it is possible to refine by collection classification by local governments including “combustible waste”, “non-combustible waste” and “oversized waste” as treatment handling routes. The user who performs the evaluation can arbitrarily extract the distribution ratio data necessary for determining the distribution ratio in the modeled process flow from the table and use it. The classification rank is selected from the items of the classification rank determined to be most suitable for the evaluation target, and necessary distribution ratio data is extracted from this item row and used.
[0207]
The user who performs the evaluation performs a comprehensive classification and arrangement based on the waste statistics shown in FIG. 18 and selects the most appropriate classification from a database prepared in advance. Since the distribution ratio can be determined, it is possible to perform simple and precise environmental load evaluation in a short time.
[0208]
In this system, it is possible to make an evaluation target a simple model and evaluate the environmental load. Although it is the original form to accumulate actual values, the present invention uses statistical data and a modeled flow for the case where the designer (evaluator) wants to easily create an environmental load. As a result, it is possible to grasp a rough value such as what [%] for landfill per recycling, what [%] for recycling, and what [%] for incineration.
[0209]
Next, specific examples of results obtained by actual evaluation using this system will be described in detail.
[0210]
<Evaluation Example 1>
Recyclability evaluation was performed on product A of the metal-based mixed material. The main composition of the product A is an iron-based component 50 [%], a copper-based component 40 [%], and an iron-zinc-based component 10 [%]. Recyclability evaluation was performed on the entire undecomposed product. When the mixing allowance data when iron and copper are mixed is extracted from the metal mixing allowance database as shown in FIG. 16, the evaluation is “C ((detail) recommendation for separation, improved dismantling required, (classification) refining). In this case, the evaluation result shows that the product A is difficult to remove by refining if it is not decomposed.
[0211]
Moreover, the mixture of copper and iron is not marketable.
[0212]
Therefore, by the processing according to the recycling content determination flow of FIG. 10, the product A subject to recycling evaluation is metal and the amount of impurities is NG (S110, S111), and the ease of removal and compatibility are NG (S112, S113). ), It is judged as “disposal” as the processing content because there is no marketability.
[0213]
As a result, the recyclability of iron / copper mixed parts having no value in the scrap market is judged to be low, and the recyclability rate is calculated as 0 [%]. Actually, the iron and copper mixed products in the scrap market are low in value, and most of them are disposed of in landfill, and the calculation accuracy of the actual recyclability rate is improved.
[0214]
Thus, since the evaluation result that the product A is not suitable for recycling is obtained as it is, it will be evaluated how it will be disassembled in order to open up a way to recycle even a little.
[0215]
Since product A was a composition composed of a combination of copper-based parts and iron-based and iron-zinc-based parts, therefore, in this case, the level of product A was increased to disassemble and separate the copper-based parts, We will evaluate the recyclability of what happens when the design allows disassembly and separation into two parts, copper-based parts and iron-based and iron-zinc-based parts.
[0216]
In order to investigate product A under these conditions, when mixing admissibility data in the case where iron and zinc are mixed is extracted from the metal mixing allowance database of FIG. 16, the evaluation result is “A” ((detail) reproduction) Suppose that there is potential demand for goods, (classification) refining separation is possible, or there is an alloy application). From this, if product A has a structure that can be separated into two parts, copper-based parts and iron-based and iron-zinc-based parts so that the copper-based parts can be disassembled and separated, product A can be disassembled to this level It can be seen that zinc can be removed and separated by refining by separating and collecting.
[0217]
Further, according to the recycling content determination flow of FIG. 10, it is determined that there is a high possibility that the material content can be recycled as a component material of the same level without processing such as refining for a copper component that is a single component. Since it is judged that closed-type material recycling that can be reused for the same application is possible within the manufacturer without refining by an external processing company, the recycling rate is as a copper-based part. It is output as 100 [%].
On the other hand, although not a single component, iron and iron-zinc-based parts for which removal and separation technology has been established can be recycled by refining treatment such as Yamamoto reduction. Therefore, it is judged that these iron and iron-zinc components can be subjected to open-type material recycling (that is, material recycling that requires refining by an external processor). In the evaluation, the recycle yield rate by refining is considered, and as a result, the recycle rate as iron and iron-zinc system parts is output as 90%, for example.
[0218]
As a result, if the product A, which has been determined to have a recyclability rate of 0 [%] in the undisassembled state, can be separated by disassembling parts containing mixed non-permissible materials, the product A will be recycled. In this case, it is possible to secure a recyclability rate of 95 [%] as a whole product obtained by integrating copper-based parts 50 [%] and iron and iron-zinc-based parts 45 [%]. It becomes clear by analysis.
[0219]
Furthermore, using the processing method and part weight determined by the above recyclability evaluation, the disposal / recycling cost per unit weight for each processing method extracted from the disposal / recycling processing classification / basic unit database in FIG. The selling price can be integrated to calculate the disposal / recycling cost under the evaluation conditions in this evaluation example. If the product is not disassembled, it is determined that it is all discarded, so the landfill disposal cost is calculated as 40 yen per product. If the product is disassembled, the dismantling cost, the cost for crushing and sorting the iron parts, and the sale price of the recovered product are integrated, and it can be seen that a profit of -50 yen, that is, 50 yen recycling can be obtained.
[0220]
FIG. 20 shows an example of a display screen for the recyclability evaluation result. In the example of FIG. 20, the output condition such as whether to distinguish the range to be included in the recycling according to the range of the processing method or whether the sale price of the collected product is paid or not is set and displayed, and the product profile such as the product name, Recyclable mass, waste mass, recyclability rate, disposal recycling cost, etc. are displayed. Furthermore, comparison data such as trial calculations at different dismantling levels for different products or the same product can be displayed. When it is desired to obtain detailed information about the evaluation contents in parts or processing methods, it can be displayed on a separate screen that can be called from this screen. In FIG. 20, the range included in the recycling is limited to reuse, material recycling for the same application, and material recycling for cascade use, and only when the collected items are collected for a fee is added to the recyclable mass. As a product recyclability evaluation result, the evaluation result when the product A in this evaluation example is disassembled into an iron-based part and a copper-based part is displayed. In the comparative data, the result of evaluating the recyclability of the product A as it is without disassembling the product A in this evaluation example is transcribed and displayed.
[0221]
In this way, the evaluation of recyclability that reflects the mixed state of materials improves the accuracy of the evaluation, clearly shows the effect of improving recyclability by dismantling, and to what level it can be dismantled It will be possible to know the specific numerical value of whether the recyclability rate can be secured.
[0222]
Furthermore, environmental load evaluation was performed using the value of recycling content and recycling rate derived as described above. In product design, the environmental impact assessment results fluctuate to reflect the selection of metal materials to be used in combination in one product and the examination content such as which parts to which level and how easy to disassemble It has become possible to design environmentally conscious products in more detail.
[0223]
<Evaluation Comparative Example 1>
This evaluation comparative example 1 is an evaluation example according to a conventional method, and is an evaluation of the product A shown in Example 1. Since iron and copper are originally recyclable materials, they are treated as recyclable materials considering only the material names, and therefore, each is accumulated as a recyclability rate of 100 [%]. And even if it is the part with iron and copper mixed, it will calculate with a recycling rate of 100 [%]. As a result, an evaluation result that largely deviates from the evaluation of the value in the actual scrap market is output. Also, in the evaluation assuming that the copper-based parts and the iron and iron-zinc-based parts are disassembled in advance, the total is also calculated as 100 [%]. For this reason, in the conventional method, the effect of improving the recyclability by dismantling is completely unknown, and it is impossible to judge the necessity of dismantling.
[0224]
<Evaluation Example 2>
Recyclability evaluation was performed on the product B of the plastic-based mixed material by the system of the present invention. The main composition of the product B is: polyethylene (hereinafter abbreviated as PE) system part 30 [%], polyvinyl chloride (hereinafter abbreviated as PVC) system part 20 [%], polystyrene (hereinafter abbreviated as PS). ) System parts 40 [%], polymethyl methacrylate (hereinafter abbreviated as PMMA) 10 [%].
[0225]
Recyclability was evaluated for the entire undecomposed product. From the plastic mixing allowance database of FIG. 15, the mixing allowance data of the four types of materials contained is extracted.
[0226]
As a result, it can be seen that the combination of PE and PMMA has low mixing tolerance from the viewpoint of compatibility or a development example of a compatibilizing agent and marketability. Further, according to the recycling content determination flow of FIG. 10, it is determined that the processing content is equivalent to one-way material recycling such as conversion to blast furnace reducing material, or heat recovery after solid fuel conversion or oil conversion processing. As a result, it is determined that the waste plastic of the product B can only be cascade recycled as a low-level product.
[0227]
The recyclability rate is calculated as 0 [%] when the range to be included in recycling is limited to material recycling as a material. In the actual waste plastic market, the value of the plastic mixture as a material raw material is low, and the accuracy of the recyclability rate is increased.
[0228]
Next, let's evaluate the recyclability when the product B can be disassembled and separated into two parts: PE and PVC parts, and PS and PMMA parts by raising the disassembly level.
[0229]
Based on this condition, extracting polymer admissibility data when PE and PVC are mixed from the plastic admixture database shown in FIG. 15 enables polymer alloying with a compatibilizer, and PE-PVC. It can be seen that marketability can be expected to some extent because of the presence of commercially available polymer blends.
[0230]
In addition, according to the recycling content determination flow of FIG. 10, the processing content is not a single component and separation and removal is completely difficult, so closed-type material recycling to the same application is impossible. It is judged that open-type material recycling for other uses is possible. The recycling yield rate is taken into consideration, and the recycling rate as PE and PVC parts is output as 80 [%].
[0231]
On the other hand, when mixing tolerance data when PS and PMMA are mixed is extracted, there are cases of polymer alloying by a compatibilizer, but there is no commercial product of PS-PMMA polymer blend, so characteristics and practicality From this point of view, it can be seen that marketability as a material cannot be expected at present.
[0232]
Further, according to the recycling content determination flow of FIG. 9, it is determined that the processing content is equivalent to one-way material recycling such as blast furnace reducing material, or heat recovery after solid fuel conversion or oil conversion processing. As a result, it is judged that PS and PMMA mixed parts can only be cascade recycled as low-level products. The recyclability rate is calculated as 0 [%] when the range to be included in recycling is limited to material recycling as a material.
[0233]
As a result, by disassembling, the product that has been judged to have a recyclability rate of 0 [%] can be designed to allow parts containing mixed non-permissible materials to be separated by dismantling. It becomes clear that the parts 40 [%] and PS and PMMA-based parts 0 [%] can be integrated to increase the recyclability rate to 40 [%] for the entire product. And accuracy improves by the recyclability evaluation reflecting the mixed state of the material, and the improvement effect of recyclability by dismantling is clearly shown.
[0234]
Furthermore, environmental load evaluation was performed using the value of recycling content and recycling rate derived as described above. In product design, the environmental impact assessment results fluctuate to reflect the selection of plastic materials to be used in combination in one product and the examination content such as which parts to which level and the ease of disassembly. It has become possible to design environmentally conscious products in more detail.
[0235]
For reference, an example of the output screen of the evaluation result in this case is shown in FIG.
[0236]
<Evaluation Comparative Example 2>
As a comparative example for evaluation example 2, an evaluation comparative example by the conventional method is shown.
[0237]
When PE, PVC, PS, and PMMA are each assumed to be a single component, they can be melt-remolded and integrated as a recyclable material with a recyclability rate of 100%. Even a part in which a plurality of plastics are still mixed is calculated to have a recycling rate of 100 [%], resulting in a large deviation from the evaluation of the value in the actual scrap market. Also, it is calculated as 100 [%] in the evaluation assuming that PE and PVC parts and PS and PMMA parts are disassembled in advance, so the effect of improving recyclability by disassembly is completely unknown. Therefore, it is impossible to judge the necessity of dismantling.
[0238]
<Evaluation Example 3>
Next, the recyclability of the product C made of a plastic mixed material, glass, and metal mixed material was evaluated by the system of the present invention.
[0239]
This corresponds to, for example, desktop PC recycling evaluation. In this case, the distribution ratio in the modeled flow in the disposal / recycling process for carrying out recyclability and environmental load evaluation is determined.
[0240]
As general information available in advance, about 60% of desktop PCs are sold and used nationwide for offices, 40% for homes, and general processing routes include offices. Used products from the factory are collected as industrial waste, and after intermediate treatment and weight reduction processing are performed by a processing company, they are landfilled as final disposal. Also, used products from households are coarse waste. Although it is collected as garbage or collected at retail stores and second-hand goods stores, it is also known that it is landfilled as final disposal after intermediate processing, weight reduction processing, etc. are performed by a processing company. More detailed processing content and quantity cannot be obtained without conducting a field survey.
[0241]
However, in order to suppress the economic and work burden and perform evaluation by a simple means in a short time, a classification suitable for the evaluation object is selected from the classification based on the waste classification statistics of FIG. 18 and used for the evaluation. It was to be.
[0242]
For desktop personal computers, if the iron parts of the housing and the glass of the CRT display are excluded as being recycled by the intermediate processing, it is considered that the waste plastics are most suitable as the waste classification for the rest. Therefore, the classification of waste plastics is selected, and from the intermediate processing residue, the distribution ratio of landfill disposal and the distribution ratio of incineration disposal, and the value of the residual ratio of landfill after incineration are extracted from FIG. The environmental load was evaluated using the distribution ratio.
[0243]
It was possible to evaluate the environmental load using standard values for waste treatment in Japan in a short time.
[0244]
<Evaluation Comparative Example 3>
As a comparative example for evaluation example 3, an evaluation comparative example by the conventional method is shown. When a conventional technology evaluates a product having the same conditions as in Evaluation Example 3, the result is as follows. First, the allocation ratio in the assumed processing flow is determined by collecting data through field surveys. The distribution ratio is determined based on the results of a follow-up survey of 5 treatment cases of used products, and the environmental load is evaluated.
[0245]
In this case, when actually conducted, it took about two months for the evaluation to be completed, and it required an economic and work burden for the investigation. Nonetheless, although the distribution ratio obtained is based on field surveys, the number of survey mothers is limited. The disadvantage of not being able to get left.
[0246]
For this reason, it is difficult to make the standard evaluation of the evaluation target product for the environmental load evaluation result calculated using this distribution ratio.
[0247]
In the above, various embodiments have been described. In short, the present invention is a configuration of a mixing tolerance database in which data for mixing tolerance for each material type is stored in advance, and a reuse evaluation target product (evaluation target recovered product). The input means for inputting the type and mass data of the constituent material and evaluation conditions for each part, and the input data by this input means, referring to the mixing tolerance database, the material contained in each part unit to be evaluated. Judgment means for determining mixing tolerance, and which processing is applied for each component unit to be evaluated from the mixing tolerance determination result for a plurality of types of disposal / recycling processing methods prepared in advance. Disposal / recycling classification / basic unit data that holds information such as selection method, disposal / recycling classification / basic unit, and recovery yield rate For each applicable disposal / recycling method selected by the selection means using the base, the recyclable mass, which is the amount of the evaluation target product that can be transferred to the selected disposal / recycling method, and its ratio to the total The recyclability rate is calculated, the recovery yield rate, etc. is extracted and integrated for each part. The recyclable mass and the recyclable rate are calculated, and the total recyclable mass for each part is integrated to allow the entire product to be recycled. It is characterized by comprising calculation means for calculating the mass and the recyclability rate, and display means for displaying at least one of the results obtained by these calculation means and selection means as an evaluation result.
[0248]
In the present invention, a mixing admissibility database in which data on mixing admissibility for each material type is stored in advance, and a disposal / recycling process classification / original that holds information such as disposal / recycling process classification / unit, recovery yield rate, etc. By preparing a unit database and entering the type and mass data of the constituent materials and the evaluation conditions for each component of the product subject to reuse evaluation (recovered product to be evaluated), the mixing tolerance database for this input data Referring to the above, the mixing tolerance of the material included in each component unit to be evaluated is determined, and a plurality of types of disposal / recycling methods prepared in advance are evaluated from the mixing tolerance determination result.

Therefore, it is possible to provide effective evaluation support that enables product design in consideration of recyclability.
[0251]
<Operation of recycling system>
Next, the overall operation of the recyclability evaluation system shown in FIG. 1 or 2 will be described with reference to the flowchart shown in FIG.
[0252]
Here, the operation will be described based on the recyclability evaluation system having the configuration shown in FIG.
[0253]
The processor 10 mainly creates the CAD data by executing the CAD program 105 in the memory 100 (step S601).
[0254]
The CAD data is converted into part material data by the processor 10 executing the part material data creation program 106 in the memory 100, and this part material data is stored in the part material database, for example, as shown in FIG. (Step S602).
[0255]
Next, in step S603, based on the part material data for each product stored in the part material database, the recyclability evaluation and the environmental load evaluation for the product are performed. That is, when the processor 10 executes the recyclability evaluation program 103 in the memory 100, the recyclability evaluation as described above is performed based on the component material data as shown in FIG. Further, when the processor 10 executes the environmental load evaluation program 107 in the memory 100, the environmental load is evaluated as described above based on the component material data as shown in FIG.
[0256]
Evaluation results of recyclability and environmental load are displayed on a predetermined display as the output device 14 (step S604).
[0257]
Next, when the user performs a predetermined operation, the processor 10 starts executing the improvement proposal creating process program 108 in the memory 100, and a screen as shown in FIG. 23 is displayed on the display as the output device 14. Is done.
[0258]
As shown in FIG. 23, from the area R1 on this screen, one of the recyclability, the environmental load, and the generated cost can be selected as an improvement item. When the user selects one of these three items, next, for example, recyclability is selected as an improvement item in the region R12 based on the evaluation result of recyclability and environmental load described above. Are listed in order of increasing non-recyclable mass among the parts / materials constituting the product. Further, when the environmental load or the generated cost is selected as the improvement item, the parts / materials are listed in order of increasing environmental load or cost among the parts / materials constituting the product. In addition, for each part / material displayed in the region R12, analyze the cause of poor recyclability (inhibition factor of recyclability) / the cause of high environmental load and cost (factor of deterioration of environmental load and cost), Recyclability inhibiting factors / environmental load and cost deteriorating factors and improvement measures corresponding to these inhibiting factors / deteriorating factors obtained as analysis results are displayed in region R13 (steps S605 to S606).
[0259]
As improvement measures, there are a case where the evaluation conditions used in the evaluation of recyclability and environmental load (including cost) are changed, and a case where parts material data is improved.
[0260]
Recyclability hindering factors / environmental load and cost deteriorating factors displayed in area R13, and improvement measures corresponding to these hindering factors / deteriorating factors (if these are displayed, select one of them by the user) For example, a list of alternative parts / materials, a list of alternative recycling methods, parts that can be disassembled, etc. are displayed on the screen of FIG. It is displayed in region R14.
[0261]
When a desired one is selected from the alternative parts / materials, the alternative recycling method, and the parts that can be disassembled displayed in the region R14 on the screen shown in FIG. 23 (pointing with a mouse or the like) When a selection operation such as clicking is performed on the device), the data corresponding to the selected part / material among the part material data stored in the part material database is temporarily changed, or the evaluation condition is changed. For example, the recyclability and the effect of improving the environmental load (including cost) in such a change are estimated (step S607 to step S608).
[0262]
Note that the part material data and evaluation conditions to be changed here are only temporary, and the part material data, recyclability, and environmental load (costs) stored in the part material database used in step S603 are not limited. The evaluation conditions held (stored) for the evaluation of (including) are not updated at all.
[0263]
The trial calculation of the improvement effect can be realized by causing the processor 10 to execute the recyclability evaluation program 103 and the environmental load evaluation program 107 in the memory 100 based on the changed part material data and evaluation conditions.
[0264]
The execution of the trial calculation of the improvement effect is started, for example, by selecting an “Effect trial calculation” button B4 provided in the region R15 of FIG. 23 with a mouse or the like.
[0265]
The improvement effect evaluation result is displayed in a region R15 on the screen of FIG. 23 (step S609).
[0266]
When the user views the evaluation result and updates the part material data in the part material database or the stored evaluation condition based on the previously changed part material data or the evaluation condition, for example, on the screen of FIG. A “product data save” button B6 and an “evaluation condition save” button B6 provided in the region R16 may be selected with a mouse or the like. Then, the part material data in the part material database and the stored evaluation condition itself are updated in the same manner as the previous change contents. That is, the part material database and evaluation conditions in the storage device 16 are rewritten with the part material data and evaluation conditions used for the trial calculation of the improvement effect (steps S610 to S611).
[0267]
After updating the part material data in the part material database, a predetermined operation is performed by the user, so that the part material data is converted into CAD data including at least part names constituting the product and the quantity or number thereof. (Steps S612 to S613).
[0268]
In order to create an improvement proposal for recyclability, environmental load, and cost, the storage device 16 stores an improvement proposal basic information database. For example, as shown in FIGS. Various information tables may be held.
[0269]
In the first table shown in FIG. 31, whether or not recycling is possible for each part / material, if possible, the recycling method applicable to the part / material, the environmental load corresponding to each recycling method, Information such as a cost value is registered in advance. Further, the first table is information indicating whether or not each part / material is configured by connecting (joining) a plurality of parts / materials, and includes a plurality of parts / materials. When the material is constituted by connecting (joining) materials, the address of the link destination on the second table shown in FIG. 32 is stored. Further, in the first table, information indicating whether or not there is something specifically designated for the type of transportation means for each part / material, and when there is designation for the type of transportation means, FIG. The address of the link destination on the third table shown in FIG.
[0270]
In the second table shown in FIG. 32, whether or not a part / material connected (joined) with a plurality of parts / materials can be disassembled with respect to the part / material connected (joined) part and the connected part. Or, if disassembly is possible, the connection method of the relevant part (for example, the type of connection method such as being connected (joined) with solder or connected (joined) with screws) and the type of each connection method The type of dismantling method according to the type (for example, removing the screw by hand, drilling, melting the solder, cutting, peeling, etc.) and information such as environmental load and cost value according to the type of dismantling method Registered in advance.
[0271]
In the third table shown in FIG. 33, for parts / materials designated for the type of transportation means, the types of transportation means designated for the parts / materials and the environmental loads and cost values according to the types of transportation means. Etc. are registered in advance.
[0272]
The fourth table shown in FIG. 34 is a table in which parts / materials having the same function are classified for all parts / materials.
[0273]
The fifth table shown in FIG. 35 is, for example, actually a part / material composed of a plurality of parts / materials. Standard values such as the type of material constituting the material and its mass and density are registered, and in addition to the information shown in FIG. 35, information as shown in FIGS. 31 to 33 is registered. May be.
[0274]
Of the tables registered in the improvement proposal basic database shown in FIGS. 31 to 35, the first and second tables shown in FIGS. 31 and 32 are already stored in the storage device 16. It can be created based on information held in various databases. Therefore, if the information in the database serving as the basis is updated, the registered contents of the first and second tables in the improvement proposal basic database are also updated. In the following explanation, registration means registration as data in the base database used when creating the table, not registration in the table in the improvement proposal basic database, unless otherwise noted. Suppose it is a thing.
[0275]
When the user selects “recyclability” as the improvement item from the region R11 on the screen shown in FIG. 23, the processing operations in steps S605 to S66 in FIG. This will be described with reference to FIG.
[0276]
FIGS. 25 to 26 show the analysis method of the recyclability inhibiting factor, the recyclable inhibiting factor (cause) found as a result, and the evaluation conditions and improvement measures for the parts material data corresponding to the inhibiting factor. It shows the correspondence.
[0277]
As described above, in step S33 in FIG. 8, the recyclable mass is calculated for each part / material. At the same time, the mass that cannot be recycled for each part / material (unrecyclable mass). Can also be calculated. For example, a value obtained by subtracting the recyclable mass from the mass of the part / material can be obtained as the non-recyclable mass.
[0278]
A region R12 on the screen as shown in FIG. 23 displayed on the display as the output device 14 is based on the non-recyclable mass calculated for each component / material, and the components / materials in descending order of the non-recyclable mass. Is displayed (step S621). Then, for each displayed part / material, an obstruction factor (cause) of recyclability is analyzed (step S622).
[0279]
First, for parts / materials with a large mass that cannot be recycled (parts / materials), for example, the parts material data in the parts material database as shown in FIG. 25 to FIG. 26, A1 to A4) corresponding to the column of “Cause Check Item”.
[0280]
(A1) Is the part / material itself non-recyclable?
(A2) Is the material classification of the part / material “other”?
(A3) Is the material configuration of the part / material multiple materials?
(A4) Is the material configuration of the part / material multiple materials?
When checking whether the part / material corresponds to the above A1, for example, referring to the first table as shown in FIG. 31, the part / material registered in the first table is referred to. Check if recycling is possible. If “not recyclable” is registered here, it can be determined that the part / material is not recyclable as an impediment to recyclability (step S622). In this case, the inhibition factor “not a recyclable part / material” is displayed in the region R13 on the screen shown in FIG. 23 (step S623). Further, as an improvement measure corresponding to the inhibition factor, for example, in the method of changing the evaluation condition from FIG. 25, the part / material is registered as a recyclable part / material (for example, the first shown in FIG. 31). In the method of improving the part material data, there is a method of changing the part / material to a recyclable part / material. The region R13 on the screen shown in FIG. 5 is displayed together with the inhibition factor as means for improving recyclability corresponding to the inhibition factor (step S624).
[0281]
For example, when the user selects a method for improving the part material data among the improvement means displayed in the region R13, as a more specific countermeasure plan for the method, for example, the function is the same as the part / material. In addition, other recyclable parts / materials are displayed in the region R14 on the screen shown in FIG. 23 as candidates for changing the parts / materials (step S625).
[0282]
Here, for example, first, another part / material having the same function as the part / material is obtained with reference to the fourth table shown in FIG. Then, referring to the first table shown in FIG. 31, among these parts / materials, the parts / materials registered as “recyclable” are displayed in region R14 in FIG.
[0283]
Next, when checking whether or not the part / material corresponds to A2, the material constituting the part / material is classified as “others” with reference to the part material data shown in FIG. Check whether it exists. If it is classified as “others” here, it is not possible to determine whether or not recycling is possible due to the unknown material of the part / material, or it is applicable to the part / material corresponding to “others”, for example. It can be determined that the absence of a recycling method is an impediment to recycling (step S622). In this case, in the area R13 on the screen shown in FIG. 23, the above-described inhibition factors “unknown whether recycling is possible due to unknown material information” and “there is no recycling method applicable to the part / material” are displayed. (Step S623). Furthermore, as an improvement measure corresponding to the inhibition factor, for example, from FIG. 25, in the case of the former inhibition factor, in the method of changing the evaluation condition, there is a method of detailing the part material data for the part / material. In the case of the latter obstruction factor, the method for changing the evaluation condition includes a method of newly registering a recycling method applicable to the part / material, and these are the regions R13 on the screen shown in FIG. Are displayed together with the inhibition factor as means for improving recyclability corresponding to the inhibition factor (step S624).
[0284]
Also, from FIG. 25, in the case of the former obstruction factor, in the method of improving the part material data, the part material data registered in advance as the standard value for the part / material from the fifth table shown in FIG. Is displayed and displayed in the area R14 on the screen shown in FIG. 23 (step S625). Also, from FIG. 25, in the case of the latter hindrance factor, in the method of improving the part material data, the recycling method applicable to the part / material is read from the first table shown in FIG. Is displayed in the area R14 on the screen shown in FIG. 23 (step S625).
[0285]
Next, when checking whether or not the part / material corresponds to the above A3, for example, referring to the part material data shown in FIG. 7, whether or not the part / material is composed of a plurality of materials. To check. If it is composed of a plurality of materials (a material corresponds to a large category of materials, for example, it is composed of metal and plastic), the recoverable material and the recycling rate are limited. It can be determined that this is an obstructive factor for recyclability (step S622). In this case, in the area R13 on the screen shown in FIG. 23, the inhibition factor “in the case of multiple materials, the recoverable material and the recycling rate are limited” is displayed (step S623). Further, as an improvement measure corresponding to the obstruction factor, for example, in the method of changing the evaluation condition from FIG. 25, there is a method of dissociating a different material and setting it to another part / material. Since there is a method of changing the parts / materials to those composed of a single material, these correspond to the above-described inhibition factors in the region R13 on the screen shown in FIG. It is displayed together with the inhibition factor as means for improving recyclability (step S624).
[0286]
For example, when a method for changing the evaluation condition is selected by the user from among the improvement means displayed in the region R13, as a more specific countermeasure plan for the method, for example, a part where the part / material can be disassembled is selected. The text or image is displayed in the area R14 on the screen shown in FIG. 23 (step S625).
[0287]
Here, for example, first, referring to the first table shown in FIG. 31, the presence / absence of a disassembly location for the part / material is checked. If there is a disassembly location, the second table is further referred to. Then, the location where disassembly is possible is determined from the disassembly location for the part / material and whether or not the disassembly is possible. Then, in the region R14 of FIG. 23, for example, the disassembling part is displayed in the image of the part / material.
[0288]
Further, for example, when the method for changing the part material data is selected by the user from among the improvement means displayed in the region R13, as a more specific countermeasure plan for the method, for example, a material in the part / material The configurations are displayed in the area R14 on the screen shown in FIG. 23 in descending order of mass (step S625). Here, for example, from the component material data shown in FIG. 7, the total value of the mass is calculated for each material for the part / material, and the region R14 on the screen shown in FIG. 23 in descending order of the total value. To display.
[0289]
When checking whether the part / material corresponds to the above A4, for example, referring to the part material data shown in FIG. 7, it is checked whether the part / material is composed of a plurality of materials. To do. If it is composed of a plurality of materials (the material corresponds to the sub-category of the material, for example, it is composed of metal 1, metal 2, etc. among materials called metals), mixed If it is not possible to determine the allowance, it is determined that recycling is not possible, so that it can be determined that this is an impediment to recyclability (step S622). In this case, the inhibition factor is displayed in a region R13 on the screen shown in FIG. 23 (step S623). Furthermore, as an improvement measure corresponding to the obstruction factor, for example, in the method of changing the evaluation condition from FIG. 26, there is a method of disassembling (possible) for each material type to form a plurality of parts / materials. In the method of improving material data, there are a method of changing to a component / material made of a single material and a method of changing a material that cannot be mixed and allowed to be mixed to a material that can be mixed, and these are shown in FIG. In the region R13 on the screen, it is displayed together with the inhibition factor as means for improving the recyclability corresponding to the inhibition factor (step S624).
[0290]
For example, when the user selects a method for changing the evaluation condition from among the improvement means displayed in the region R13, as a more specific countermeasure plan for the method, for example, in the same manner as described above, The parts that can be disassembled are displayed as text or images in a region R14 on the screen shown in FIG. 23 (step S625).
[0291]
When the former of the two methods for improving the part material data among the improvement means displayed in the region R13 is selected by the user, as a more specific countermeasure plan for the method, for example, the part / The material composition in the material is displayed in the region R14 on the screen shown in FIG. 23 in descending order of mass (step S625). Here, for example, from the part material data shown in FIG. 7, the total value of the mass is calculated for each material for the part / material, and the region R14 on the screen shown in FIG. 23 in descending order of the total value. To display.
[0292]
Further, when the latter of the two methods for improving the part material data among the improvement means displayed in the region R13 is selected by the user, as a more specific countermeasure proposal of the method, Then, parts / materials that are allowed to be mixed with other materials are displayed as change candidates in the region R14 on the screen shown in FIG. 23 (step S625). Alternatively, other parts / materials that have the same function as the parts / materials and that are made of recyclable different materials or single materials may be displayed as change candidates.
[0293]
Here, for example, the metal mixing allowance information, which is information on the availability of the metal mixture, and the plastic mixing allowance, which is the information on the availability of the plastic mixture, are stored in the recyclability evaluation information database 160. By referring to “mixing admissibility” by material such as sex information, the above-mentioned specific plan can be created and displayed.
[0294]
The processing operation in steps S605 to S66 in FIG. 22 in the case where the user selects “environmental load” or “occurrence cost” as the improvement item from the area R11 on the screen shown in FIG. 23, according to the flowchart shown in FIG. This will be described with reference to FIGS.
[0295]
28 to 30 show the analysis method of the environmental load and cost deteriorating factors, the deteriorating factors (causes) found as a result thereof, and the correspondence between the evaluation conditions corresponding to the deteriorating factors and the measures for improving the part material data. It shows the relationship.
[0296]
In the following description, the present system will describe a case where the environmental load and cost are calculated for a process from collecting a product as waste, disassembling it, and recycling it. Furthermore, the environmental load and cost which arise from each process may be calculated about all the processes from the manufacturing process of a product to collection, dismantling, and recycling processes.
[0297]
The environmental load unit and cost generated when collecting a product as waste vary depending on the type of transportation means such as a truck that transports the product. Further, the environmental load unit and cost generated at the time of dismantling differ depending on, for example, the type of dismantling method (means). Therefore, in this system, the environmental load intensity database is created in the environmental load intensity database by, for example, the type of transportation means or the type of dismantling method (means) created based on the Input-Output Law or obtained from literature. Is stored separately, and is input separately from the parts material database, and indicates data indicating the type of transport means, transport distance, type of dismantling method, etc. for each product (this is also stored in the storage device 16). And the environmental load basic unit stored in the environmental load basic unit database, the environmental load and cost at the time of collection and dismantling are calculated.
[0298]
In this way, the environmental load evaluation device calculates the environmental load and cost generated for each part / material for each process of product collection, disassembly, and recycling, and also from the entire life cycle of the product. It has become. Therefore, the improvement plan created here is also to improve the environmental load and cost generated from the entire product life cycle (at least the recycling process from product collection to disassembly and recycling). .
[0299]
In the following description, the case where “environmental load” is selected as the improvement item will be described, but the same applies when “occurrence cost” is selected. That is, in the following description, “environmental load” may be replaced with “occurrence cost” or “cost”, and therefore, description when “occurrence cost” is selected as an improvement item is omitted.
[0300]
In the region R12 on the screen as shown in FIG. 23 displayed on the display as the output device 14, the parts / materials are displayed in order of increasing environmental load based on the environmental load calculated for each part / material. (Step S631). Then, the environmental load deterioration factor (cause) is analyzed for each displayed part / material (step S632).
[0301]
First, for parts / materials having a large environmental load (parts / materials), by comparing the environmental load values calculated for each process for the parts / materials, a recycling process (cause check item B1 in FIG. 28) is performed. And the transport process at the time of collection (corresponding to the cause check item B2 in FIG. 29) and the dismantling process (corresponding to the cause check item B3 in FIG. 30) to check whether the environmental load is the largest. (In FIGS. 28 to 30, B 1 to B 3 corresponding to the column “Cause Check Item”).
[0302]
When the part / material corresponds to the above B1, it can be determined that the environmental load is deteriorated by performing a recycling process with a large (high) environmental load on the part / material (step S632).
[0303]
In this case, the deterioration factor is displayed in the region R13 on the screen shown in FIG. 23 (step S633). Further, as an improvement measure corresponding to the deteriorating factor, for example, from FIG. 28, in the method of changing the evaluation condition, a method of selecting a process with a small environmental load from among recycling processes applicable to the part / material. In the method of improving the part material data, there is a method in which the part / material is changed to a part / material applicable to recycling processing with a small environmental load, and these are displayed on the screen shown in FIG. In area R13, it is displayed together with the deterioration factor as means for improving the environmental load corresponding to the deterioration factor (step S634).
[0304]
For example, when the method for changing the evaluation condition is selected by the user from among the improvement means displayed in the region R13, as a more specific countermeasure plan for the method, for example, a recycling method applicable to the part / material. (Recycling process) is displayed in the region R14 on the screen shown in FIG. 23 as change candidates in order from the one with the smallest environmental load (step S635).
[0305]
Here, for example, first, referring to the first table shown in FIG. 31, the applicable recycling method for the relevant part / material is read out and displayed in the region R14 in FIG. Is done.
[0306]
Further, for example, when the method for changing the part material data is selected by the user from among the improvement means displayed in the region R13, for example, the part / material and the function may be used as a more specific countermeasure plan for the method. The same parts / materials are displayed as change candidates in the region R14 on the screen shown in FIG. 23 in order from the one with the least environmental load of the recycling method applicable to the parts / materials (step S635).
[0307]
Here, for example, first, another part / material having the same function as the part / material is obtained with reference to the fourth table shown in FIG. Then, referring to the first table shown in FIG. 31, the recycling method applicable to these parts / materials and the environmental load thereof are read out, and in order of the parts / materials applicable to the recycling process with a small environmental load, It displays in area | region R14 of FIG. Or you may make it display the area | region R14 on the screen shown in FIG.
[0308]
When the part / material corresponds to the above B2, it can be determined that the transportation of the part / material with a large environmental load is a cause of deterioration of the environmental load (step S632).
[0309]
In this case, the deterioration factor is displayed in the region R13 on the screen shown in FIG. 23 (step S633). Further, as an improvement measure corresponding to the deteriorating factor, for example, from FIG. 29, in the method of changing the evaluation condition, a method of selecting a means with a small environmental load from the transportation means applicable to the part / material. In the method of improving the part material data, there is a method in which the part / material is changed to another part / material applicable to a transportation means with a small environmental load. In the upper region R13, it is displayed together with the deterioration factor as means for improving the environmental load corresponding to the deterioration factor (step S634).
[0310]
For example, when the method for changing the evaluation condition is selected by the user from among the improvement means displayed in the region R13, as a more specific countermeasure plan for the method, for example, a transport means applicable to the part / material. Are displayed in the region R14 on the screen shown in FIG. 23 as candidates for change in order of increasing environmental load (step S635).
[0311]
Here, for example, first, referring to the first table shown in FIG. 31, the presence / absence of designation of transportation means is checked for the part / material, and when the transportation means is designated, it is shown in FIG. With reference to the third table, applicable transportation means are read out and displayed in the region R14 of FIG. 23 in order from the one with the smallest environmental load. Check whether or not the means of transportation is specified for the part / material. If no means of transportation is specified, for example, based on the environmental load factor for each type of means of transportation registered in the environmental load unit database. You may make it display the kind of transport means in area | region R14 of FIG. 23 in an order with a small value.
[0312]
Further, for example, when the method for changing the part material data is selected by the user from among the improvement means displayed in the region R13, for example, the part / material and the function may be used as a more specific countermeasure plan for the method. The same parts / materials are displayed as change candidates in the region R14 on the screen shown in FIG. 23 in order from the smallest environmental load of the transportation means applicable to the parts / materials (step S635).
[0313]
Here, for example, first, another part / material having the same function as the part / material is obtained with reference to the fourth table shown in FIG. Then, with reference to the first table shown in FIG. 31, the presence / absence of designation of transportation means is checked for these parts / materials. When the transportation means is designated, the third table shown in FIG.
