Description

  The present invention relates to a component management processing system capable of managing individual components when performing sheet metal processing in a processing machine.

  In the environment surrounding sheet metal processing in recent years, the demands for variable-variable-variable production and short-delivery production are further accelerating. Understanding has become a very important factor in delivery date management.

Generally, in the sheet metal bending process, each part is processed, so it is easy to grasp the process for each part. However, in the sheet metal drilling process, multiple programs are combined into one worksheet in consideration of processing efficiency and yield. Since nesting and many pieces are often taken, it is difficult to grasp individual parts.

  In turret punch press processing, the processing program is not organized into parts by tool sort, and there are cases where a single punch or laser cutting may span multiple parts, such as width sharing. It becomes complicated.

  Even in the conventional technology, there was one that could automatically notify the completion of a part when processing of one sheet was completed, but there was no identification of each part, and all included parts were notified at the same time when sheet processing was completed It was to be done. In addition, only the completion of processing could be identified, and it was not possible to grasp the unstarted / started, progress rate, etc.

  In such a situation, the one sheet with a long processing time has a large time divergence from the progress of the parts, which is inconvenient in the case of ultra-short delivery such as within 8 hours. In situations where the user is demanding more detailed and real-time progress management than ever before, such a long processing time for one sheet has been a problem.

  With regard to grasping the completion of parts processing, it is not possible to discriminate each part with the conventional technology. If an interruption occurs due to an alarm or the like during processing of one sheet, the operator can track the processing status individually while viewing the processing status individually. Even though there are parts that are registered or actually completed as non-defective products, all the parts included in the sheet must be reworked as defective products.

  Furthermore, recently, it has become necessary to manage how much energy and cost it takes to process individual parts. However, regarding the amount of energy consumed, the total amount of processing for one sheet is calculated based on the number of hits and the length of the laser cutting path. It was prorated according to the ratio. However, since it actually changes every moment depending on the movement command and the processing method, the result calculated by the above-described method does not coincide with the actual result, and there is a problem that the error increases.

  Next, the processing of step 101 in FIG. 4 will be described in detail with reference to FIG.

  FIG. 5 is a flowchart showing the operation of the process in step 101 of FIG.

  In step 201 in FIG. 5, the CAM system 7 assigns punching to the graphic data after nesting based on a plurality of types of input part shape data and data on the workpiece (worksheet W), etc. Is generated. FIG. 6B is a diagram illustrating an example of the input plural types of component shape data, and FIG. 6C is a diagram illustrating an example of the allocation. As shown in FIG. 6B, here, assuming that three parts A, five parts B, and four parts C are input as the assigned part shape data, as shown in FIG. In addition, part A, part B, and part C are assigned to the worksheet W. That is, the part refers to a product obtained by processing from the worksheet W.

  Here, the allocation data covers a part processing method and coordinate information. Here, the CPU 76 functions as a processing assignment processing unit.

  Next, in step 203, a G code is output based on the generated allocation data. FIG. 6A shows an example of the G code processing program. Here, the relationship between the generated allocation data and the G code execution block is also obtained. Here, the CPU 76 functions as a G code output processing means.

  Next, in step 205, time ratio data is generated from the allocation data, G code, processing conditions, press pattern, and servo parameters. FIG. 7 is a diagram illustrating an example of the time ratio data.

  Here, as shown in FIG. 7, the time ratio data includes part information for all the arranged parts, and the part information includes laser information and punch information.

The machining time is determined by the speed according to the servo parameters and the press pattern when there is punching. The corresponding G code execution block is obtained from the allocation data.

  Here, the CPU 76 functions as an execution time ratio calculation processing means.

  Next, in step 207, the part progress information is obtained by accumulating the time ratio every time the execution block advances, and the part performance information is obtained by using the time ratio as it is. FIG. 8 is a diagram illustrating an example of component progress information, and FIG. 9 is a diagram illustrating an example of component performance information. 8 and 9 correspond to the components and allocation shown in FIGS. 6 (b) and 6 (c).

  That is, the part progress information is a part progress information table as shown in FIG. 8. For example, when the execution block number advances to 14, punch processing is performed, the part can be specified, and the part A-1 is 100.0% processed, part A-2 is 33.0% processed, and the other parts are 0.0%, that is, no processed Show. Then, the part result information is a part result information table as shown in FIG. 9. For example, when the execution block number advances to 14, it is punch processing, the part can be specified, and the part A-2 is This indicates that the distribution ratio is 100.0%, and other parts have a distribution ratio of 0.0%. In the part result information table shown in FIG. 9, for example, when the execution block numbers are 1 to 8, the parts cannot be specified, and therefore, the distribution ratio is equally divided into all parts. In the numbers 20 and 21, although the parts can be specified, the parts are divided into a plurality of parts, so that the distribution ratio is equally divided into the parts.

  Execution blocks that are not associated with components are not accumulated, and execution blocks that are not associated with components are prorated according to the number of components. Here, the CPU 76 functions as a partial progress and component performance calculation processing means.

  The above operation by the CAM system 7 is shown as a functional block in FIG. FIG. 10 is a functional block diagram of the operation by the CAM system 7.

  Next, the processing of step 105 in FIG. 4 will be described in detail with reference to FIG. FIG. 11 is a flowchart showing the operation of the process of step 105 in FIG.

  In step 301 of FIG. 11, only the machining program (G code) of the data called from the database 5 is written into the CNC by the machining program transfer processing unit 19. In step 303, the machining program execution processing unit 21 executes the machining program. The processing machine 11 is operated while interpreting (G code).

  In step 305, the operation sequence execution processing unit 39 drives a solenoid valve or the like when actuator operation is required based on an instruction from the machining program execution processing unit 21, and in step 307, a multi-piece execution number acquisition processing is performed. When the machining program is a multi-piece taking program and is being executed by the unit 23, the number of execution lines of the multi-piece taking is acquired.

  In step 309, the execution line acquisition processing unit 25 acquires what line of the machining program is being executed. In step 311, the execution block derivation processing unit 27 acquires the multi-piece execution number acquisition processing unit 23. Based on the component progress information from the database 5, the execution block number is derived from the number of executed lines and the number of executions acquired by the execution line acquisition processing unit 25.

  In step 313, the component progress calculation processing unit 29 uses the component progress information from the database 5 and the execution block number from the execution block derivation processing unit 27 to obtain the current information from the information that matches the execution block number of the component progress information. The progress state for each part is calculated. That is, from the part progress information table shown in FIG. 8, for example, when the execution block number advances to 14, it is punch processing, the part can be specified, and part A-1 has been processed by 100.0%. The part A-2 has been processed by 33.0%, and the other parts are calculated by 0.0%, that is, that the processing has not yet been performed.

  In step 315, the progress information calculated by the component progress calculation processing unit 29 is notified to the result collection system 9 sequentially during processing, at the end of processing, and at the time of interruption by the component progress notification processing unit 31.

  In step 317, the accumulated energy is obtained from the detection systems 17 attached to various parts of the processing machine 11 by the consumed energy obtaining integration processing unit 33, the cumulative number of operation times of the actuator 49, and they are operated once. Is calculated from the actuator operating parameter, and the integrated value and the consumed energy amount are multiplied and integrated. Here, the actuator operating parameter measures in advance how much energy (electric power, air, gas, oil) is consumed when the actuator operates at one time in order to obtain energy consumption without using a flow meter. This parameter is held for each actuator.

  In step 319, every time the execution block changes, the integrated value is acquired and stored from the energy consumption acquisition integration processing unit 33 by the component result calculation processing unit 35. The next time the execution block changes, the energy consumption again. The integrated value is acquired from the acquisition integration processing unit 33, the difference from the stored value is obtained, and the difference value is distributed for each part using the value of the execution block having the same part performance information as the energy consumption of one execution block. Then, the obtained energy consumption for each execution block is integrated into the part result result data, and the part result result data (see FIG. 12) is obtained. That is, from the part performance information table shown in FIG. 9, for example, when the execution block number advances to 14, it is punch processing, the part can be specified, and the energy consumption is distributed to the part A-2 at a distribution ratio of 100.0%. Since the other parts are distributed at a distribution ratio of 0.0%, they are not distributed.

  FIG. 12 is a diagram illustrating an example of part performance result data.

  Since the processing machine 11 is a multi-function machine that performs punching and laser processing, the execution block has information on processing attributes (punch processing or laser processing). Based on this, punching and laser processing are integrated separately.

  In step 321, when the machining program ends or is interrupted by the component result notification processing unit 37, the component result result data from the component result calculation processing unit 35 is notified to the result collection system 9.

  When the component progress notification processing unit 31 notifies the component progress information to the performance collecting system 9 one by one, and the component result notification processing unit 37 notifies the component result result data to the performance collecting system 9 one by one, as described above, The result collection system 9 stores the part progress information and the part result information in the database 5 and simultaneously displays the real-time part progress information and the part result information as a graph and also displays the past results and trends as a graph. .

  Further, these data stored in the database 5 are used for estimation calculation, carbon footprint calculation, and the like by other production management systems (not shown).

  As described above, according to the present embodiment, the progress information for each part is obtained sequentially during machining, at the end of machining, and at the time of interruption, and the part performance information for each part when the machining program ends or is interrupted. .

  Therefore, since the user can grasp the progress rate of each part sequentially and at the end of machining and at the time of interruption during machining, since the progress of the parts can be understood for each of the sheets with a long machining time, Detailed and real-time progress management can be performed even in the case of ultra-short delivery times such as within 8 hours.

  In addition, since it is possible to determine the completion of part processing for each part, even if it is interrupted by an alarm or the like during processing of one sheet, it is possible to accurately grasp the part that is actually completed as a non-defective product. it can. For this reason, even when an interruption occurs due to an alarm or the like during the processing of one sheet, it is possible to solve the inefficient problem of reworking all parts included in the sheet as defective products.

  In addition, it is possible to meet the recent need to manage how much energy and cost is required for individual part processing, and the amount of energy consumed also varies with the actual movement command and processing method. However, you can know how much energy and cost it costs to process individual parts.

  The present invention is not limited to the embodiments of the invention described above, and can be implemented in other modes by making appropriate modifications.

  For example, in the above embodiment, the result collection system 9 is a system different from the CAM system 7, but the result collection system 9 may be incorporated in the CAM system 7.

  In the above embodiment, the result collection system 9 displays the real-time component progress information and the component result information in a graph or the like using the component progress information and the component result information. The result information may be used in other ways.
