Description

The present invention relates to a management system and management method suitable for managing, for example, molds necessary for manufacturing parts.

Major products such as automobiles, home appliances, communication equipment, and medical equipment are diversifying due to diversification of user preferences, and the number of product types is increasing as they are sold all over the world. On the other hand, there is also a need to continually introduce new products to stimulate purchasing power, which is causing product lifespans to become shorter. The product cycle has become so-called multi-product, small-lot, and short-lived products.

Products are made up of many parts, including many plastics, sheet metals, rubber, and die-cast parts, all of which are manufactured using molds, and the number of molds is inevitably increasing to accommodate a wide variety of products.

Once a product is sold on the market, it enters a ``repair period'' after its sales period, and its repair services will eventually be discontinued. In the case of automobiles, the repair service period is generally set at 15 years after the end of mass production (switching over to a new product). The lifespan for home appliances, information equipment, etc. is 3 to 7 years, and for manufacturing machinery 10 to 15 years.During that time, molds must be stored to manufacture repair parts, and the number of repair molds is increasing. It is in.

The Ministry of Economy, Trade and Industry is planning to publicize mold management rules that require the ordering party to pay for the storage costs of these molds, in an act of ``bullying small and medium-sized subcontractors.'' However, in the past, both the ordering and receiving parties have often ordered repair parts as parts, and both parties often do not have a mold management ledger. Furthermore, even if repair parts can be ordered, some companies leave the repair parts to secondary or tertiary subcontractors, and mold management is not carried out at the end of the company. Therefore, unless both parties manage molds in addition to conventional parts management, mold storage costs cannot be paid.

Manufacturers of mass-produced parts outsource the production of repair parts in small quantities to subcontractors, as it interferes with mass production. The ordering side of the product manufacturer manages a ledger containing the parts list and the list of suppliers, but does not manage the molds. This is because all they had to do was order the parts, so there was no need for management. On the receiving side, the molds for repair parts were poorly managed and there was no ledger, making it impossible to pay storage fees or apply for disposal. Moreover, such molds are stored in piles and are not organized.

Techniques related to the present invention are disclosed in Patent Document 1, for example.

JP2017-207950A

According to the latest Ministry of Economy, Trade and Industry guidelines, both the ordering and ordering parties need to manage molds in order to pay and receive storage fees, but this requires time and effort, and there is a possibility that discrepancies may occur on both sides. There is also. In the future, it is thought that similar problems will arise not only with molds, but also with the jigs and materials needed to manufacture the parts that make up products.

In view of the above-mentioned circumstances, an object of the present invention is to provide a management system and a management method that can accurately and wastelessly manage the disposal of molds, etc., without requiring much time and effort.

In order to achieve the above object, a management system according to the present invention manages storage of molds, jigs, or materials necessary for manufacturing parts constituting a product, and includes a product identifier that identifies the product; Data including a part identifier that identifies the part, a mass production period of the product, a repair period after the end of the mass production period, and one or more manufacturing companies that manufacture the part using the mold, tool, or material. Based on the data stored in the database, it is determined whether the repair period of the product has ended, and at the end of the repair period, the manufacturer is provided with molds, jigs, tools, or materials. notification of disposal.

In the present invention, the repair period is managed based on the data stored in the database, and at the end of the repair period, the manufacturer is notified of the disposal of molds, jigs, tools, or materials. It is possible to manage the disposal of molds, etc.

In the management system according to the present invention, at the end of the repair period, it is determined whether the part has been diverted to another product, and whether the part has been diverted to the other product, the mass production period and the repair period of the other product are determined. If the sum of the above period is longer than the sum of the mass production period and the repair period of the said product, even if the notice of disposal of said mold, tool or material is extended to the end of the repair period of said other product. good.

This makes it possible to supply parts during the repair period for diverted parts.

In the management system according to the present invention, the data stored in the database includes a product identifier that identifies the other product that uses the part, the mass production period of the other product, and the repair period after the end of the mass production period. further including, based on the data stored in the database, whether or not the parts are used for the other products, and whether the mass production period and the repair period of the other products are added together. It may be determined whether the period is longer than the sum of the period.

This makes it possible to reliably supply parts during the repair period for diverted parts without requiring any effort.

In the management system according to the present invention, based on the data stored in the database, it is determined whether or not there are two or more manufacturers after the end of the mass production period of the product, and if there are two or more manufacturers, at least It is also possible to decide to discard the molds, jigs, tools, or materials of the manufacturing destination other than the first manufacturing destination, and notify the corresponding manufacturing destination of the disposal.

This prevents unnecessary molds, jigs, or materials from remaining after the mass production period ends.

In the management system according to the present invention, when the molds, jigs, or materials necessary for manufacturing the part are manufactured by two or more of the manufacturing locations, the data stored by the database is stored at each of the manufacturing locations. Based on the data stored in the database, the molds, jigs and tools of the manufacturer are disposed of after the end of the mass production period of the product. or may regulate decisions to dispose of materials.

In the management system according to the present invention, the data stored in the database includes the notification result of notifying the manufacturing company to discard the mold, jig, or material, and the evidence of disposal from the manufacturing company in response to the notification of disposal. It may further include a returned result.

In the management system according to the present invention, the data about the mass production period and the repair period of the product stored in the database may be changeable.

A management system according to the present invention is a management system that manages storage of molds, jigs, or materials necessary for manufacturing parts constituting a product, and includes a product identifier that identifies the product and a component identifier that identifies the part. and a database that stores data including the mass production period of the product and one or more manufacturers that manufacture the part using the mold, tool, or material, and the data stored in the database. Based on this, it is determined whether or not there are two or more manufacturers after the end of the mass production period for the product, and if there are two or more good faith manufacturers, the molds and repairs of the manufacturers other than at least one manufacturer are determined. Deciding to discard the tool or material and notifying the relevant manufacturer of the discard.

Embodiments of the present invention will be described below with reference to the drawings.

[Configuration of group mold management system 1]
FIG. 1 is a block diagram showing the configuration of a group mold management system 1 according to an embodiment of the present invention.

Group mold management system 1 includes product manufacturer X that manufactures products, component manufacturers Y1, Y2, and Y3 that manufacture parts that make up the products, and subcontractors Z1, Z2, and subcontractors of these component manufacturers Y1, Y2, and Y3, It is used to manage the storage of molds necessary for manufacturing parts of the group consisting of Z3 (see Fig. 9). There are companies that are subcontractors of subcontracting companies, and one parts manufacturer or subcontracting company may have two or more subcontracting companies.

The group mold management system 1 includes a processing section 10 and a mold database 20. The processing unit 10 is configured by, for example, a PC that has a communication function or is capable of communicating with other PCs via a network using a device that has a communication function. The mold database 20 is a storage means into which data can be written and read directly from the processing unit 10 or from another PC or the like via a network.

In this embodiment, all of the product manufacturer X, component manufacturers Y1, Y2, Y3, and subcontractors Z1, Z2, and Z3 that make up the group can access the group mold management system 1 and exchange data. be. For example, subcontractors Z1, Z2, and Z3 are manufacturers that manufacture parts using molds, and store the molds. Subcontractors Z1, Z2, and Z3 need to store the molds during the repair period for manufacturing repair parts even after the mass production period ends. When the subcontractors Z1, Z2, and Z3 store the molds during the repair period, they can charge the storage fees to the parts manufacturers Y1, Y2, and Y3, and the parts manufacturers Y1, Y2, and Y3 charge the storage fees to the subcontractors Z1, Y3, and the molds. There is an obligation to pay to Z2 and Z3. In addition, parts manufacturers Y1, Y2, and Y3 may request storage fees to be paid to product manufacturer X, and product manufacturer Sometimes there isn't.

[Configuration of mold database 20]
FIG. 2 is an example of data for one part stored in the mold database 20.

The managed part number is a unique number for the part in the mold database 20.

The product number is the product number of the product in which the part is used, and if the part is shared by two or more products, two or more product numbers are set.

The part number is the part number of the part in the product in which the part is used, and if the part is shared by two or more products, the part number is set for each product.

The mass production period is the mass production period of the product in which the part is used (see FIG. 8), and if the part is shared by two or more products, the mass production period is set for each product. The set mass production period can be changed. This is because it is necessary to change it according to the life of the product (see Fig. 8).

The repair period is the repair period of the product in which the part is used (see Figure 8). The repair period is a period that is required or voluntarily set by the product manufacturer to repair the product after the end of the mass production period. Regarding the repair period, if this part is shared by two or more products, a repair period number is set for each product. The set repair period can be changed. This is because changes need to be made due to amendments to laws, etc.

The mold management number is a management number of a mold necessary for molding the part. If there are two or more manufacturers that manufacture this part, for example, if subcontractors Z1 and Z2 each use a mold to manufacture the part, the mold control number will be unique to each mold of that manufacturer. is set to For example, a mold management number for a mold stored by subcontractor Z1 and a mold management number for a mold stored by subcontractor Z2 are set separately.

The asset management number is a number for managing mold assets. An asset management number is set for each mold. For example, the asset management numbers of the molds stored by subcontractor Z1 and the molds stored by subcontractor Z2 are set separately.

The company QR is a QR code (registered trademark) for accessing information about the company that stores the mold, the company that pays the mold storage fee to the company, or the company that manages payments. Shelf QR is a QR code (registered trademark) for accessing information about which shelf of the company that stores the molds stores the shelf. These QR codes (registered trademarks) make it possible to know the company that pays the storage fee for the mold, the company where the mold is stored, the location, etc.

Repair transition notification is a column that is checked when a repair transition notification is issued. When the mass production period for the part ends and the repair period begins, the company that stores the mold (the manufacturer of the part) and the company that pays the storage fee for the mold to that company or the company that manages the payment, for example, the subcontractor. Companies Z1 and Z2 and parts manufacturers Y1 and Y2 are notified that the repair period has come. The repair transition notification is that notification.

Evidence (1) is a column that is checked when repair transition evidence is returned from the company that stores the mold (parts manufacturer) in response to the repair transition notification. Repair transition evidence is proof that a mold has been transitioned from mass production to repair at the manufacturing site. Repair migration evidence will be stored separately. The date attached to this repair transition evidence may be used as the start date of storage charges. This date may be entered in the evidence (1) column or somewhere in this mold database 20.

Disposal regulation (1) is a column that is checked when regulating the disposal of molds at the manufacturing site at the end of the mass production period. When this column is checked, the decision to discard the mold at the end of the mass production period is regulated.

Disposal notice (1) is a column that is checked when a discard notice is issued at the end of the mass production period. The company that will store the mold when the mass production period for the part ends and the mold is decided to be disposed of (part manufacturing company); typically, if there are two companies, one of the companies, such as a subcontractor. Either Z1 or subcontractor Z2 is notified that the mold will be disposed of. The disposal notice (1) is that notice. Note that the notification may also be sent to the company that pays the storage fee for the mold or the company that manages the payment.

Evidence (2) is a column that is checked when disposal evidence is returned from the company that stores the mold (parts manufacturer) in response to the notice of disposal at the end of the mass production period. Disposal evidence is proof that the mold was discarded at the manufacturing site. Disposal evidence will be stored separately. The date attached to this disposal evidence may be used as the end date for storage charges. This date may be entered in the column of evidence (2) or somewhere in this database 20.

Disposal regulation (2) is a column that is checked when regulating the disposal of the mold at the manufacturer at the end of the repair period. When this column is checked, the decision to discard the mold at the end of the repair period is regulated.

Disposal notice (2) is a column that is checked when a discard notice is given at the end of the repair period. When the repair period for the part ends and the mold is decided to be disposed of, the company that stores the mold (the manufacturer of the part), the company that pays the mold storage fee to the company, or the company that manages the payment, etc. For example, subcontractors Z1 and Z2 and parts manufacturers Y1 and Y2 are notified that the repair period has come. The disposal notice (2) is that notice.

Evidence (3) is a column that is checked when disposal evidence is returned from the company that stores the mold (parts manufacturer) in response to the notice of disposal at the end of the repair period. Disposal evidence is proof that the mold was discarded at the manufacturing site. Disposal evidence will be stored separately. The date attached to this disposal evidence may be used as the end date for storage charges. This date may be entered in the evidence (3) column or somewhere in this mold database 20.

[Processing by processing unit 10]
3 and 4 are flowcharts showing the contents of processing by the processing unit 10.

The processing unit 10 refers to the mold database 20, checks the mass production period and repair period of the product number/part number corresponding to the managed part number (for example, SG51) of the part, and performs the following processing.

If the current mass production period has passed (step 301), the processing unit 10 checks whether there is another product number/part number corresponding to the managed part number (step 302). In other words, check to see if there are multiple products that use common parts.

In step 302, if there is another mold, the processing unit 10 determines to discard the mold having a mold management number of a product number/part number other than one product number/part number (step 303). In other words, if there are multiple products that use common parts and multiple molds, it is decided to keep one mold and discard the other molds. Two or more molds may be left. For example, the rate of defective products, the number of mass produced products, etc. may be used as the parameters for determining scrap. In other words, it is only necessary to leave molds with a low defective product rate or molds with a low mass production volume.

The processing unit 10 checks whether the mold determined to be discarded in step 303 has disposal regulation (1) set (step 304).

If the disposal regulation (1) is set in step 304, the processing unit 10 regulates the decision to discard the mold (step 305).

The processing unit 10 stores the mold in the company that owns the mold that was decided to leave in step 303 and the company that owns the mold whose disposal was regulated in step 305. The company that pays the fee or the company that manages the payment is notified of the transition to the mold repair period by referring to the QR code (registered trademark) of the company's QR code (step 306, see FIG. 8). If the company returns evidence in response to the notification (step 307), the processing unit 10 checks evidence (1) (step 308). A function may be provided to send a reminder if no evidence is returned within a predetermined period.

The processing unit 10 sends the QR code of the company QR to the company that owns the mold whose disposal was decided in step 303, as well as the company that pays the storage fee for the mold to the company or the company that manages the payment. (registered trademark) and notify the discard of the mold (step 309, see FIG. 8). If the company returns evidence in response to the notification (step 310), the processing unit 10 checks evidence (2) (step 311). A function may be provided to send a reminder if no evidence is returned within a predetermined period.

Figure 5 shows the case where two companies each own a common mold, and when the mass production period ends, one company discards the mold and the other company decides to store it without discarding it. An example of the mold database 20 is shown.

If the current time has passed the sum of the mass production period and the repair period (at the end of the repair period) (step 401), the processing unit 10 determines whether there is another product number/part number corresponding to the managed part number. is confirmed (step 402). In other words, check to see if there are multiple products that use common parts.

In step 402, if there is another product, the processing unit 10 determines whether the sum of the mass production period and repair period of the separately existing product is longer than the sum of the mass production period and repair period of the product. It is determined (step 403). In the example of Figure 2, when the upper row is the relevant part, the period that adds up the mass production period and repair period of the upper row component is 15 years, and the mass production period and repair period of the lower row component is 15 years. The added period is 20 years, and the added period for the separately existing parts is longer.

If the processing unit 10 determines in step 403 that the sum of the mass production period and repair period of a separate product is longer than the sum of the mass production period and repair period of the product, the processing unit 10 The notification of disposal of the part mold is extended to the end of the repair period of other products (step 404). In the example of Figure 2, if the product in the upper row is the product in question, the sum of the mass production period and repair period of the product in the upper row is 15 years, and the mass production period and repair period of the product in the lower row are 15 years. The added period is 20 years, and the added period for other products is longer. In this case, for example, as shown in FIG. 6, the repair period of the product in the upper row is made to match the repair period of the product in the lower row. Specifically, the repair period for the products in the upper row will be revised from "10 years" to "15 years." This method of extending the period is just one example, and other methods may of course be used.

On the other hand, if the processing unit 10 determines in step 403 that the sum of the mass production period and repair period of a separate product is shorter than the sum of the mass production period and repair period of the product, It is determined whether to discard the mold of the product (step 405).

The processing unit 10 checks whether the mold for which disposal has been decided in step 405 is subject to disposal regulation (3) (step 406).

If the disposal regulation (2) is set in step 406, the processing unit 10 regulates the decision to discard the mold (step 407).

The processing unit 10 sends the QR code of the company QR to the company that owns the mold whose disposal was decided in step 405, as well as to the company that pays the storage fee for the mold to that company or the company that manages the payment. (registered trademark) and notify the disposal of the mold (step 408, see FIG. 8). If the company returns evidence in response to the notification (step 409), the processing unit 10 checks evidence (3) (step 410). A function may be provided to send a reminder if no evidence is returned within a predetermined period.

FIG. 7 shows an example of the mold database 20 in a case where the company storing the molds in the upper row has already discarded the molds, and the company storing the molds in the lower row has discarded the molds.

[others]
The present invention is not limited to the above-described embodiments, and can be implemented with modifications and applications within the scope of the technical idea, and the scope of implementation also belongs to the technical scope of the present invention.

For example, in the above embodiment, an example was shown in which the present invention is applied to a mold management system that manages the storage of molds, but the present invention can also be applied to a management system that manages the storage of jigs and materials.

In the above embodiment, it is determined whether or not there are two or more manufacturing companies after the end of the product mass production period based on the data stored in the mold database 20. For example, after the end of the product mass production period, the parts company It may also be possible to inquire whether there is another manufacturer in a database held by the company or the product company.

The product identifier for identifying a product, the component identifier for identifying a listed part, etc. are not limited to the numbers and alphabets mentioned above, and may of course be in other formats. In addition, the notice of mold disposal may be given only to the company that owns the mold that has been decided to be disposed of, or only the company that pays the mold storage fee to that company, or the company that manages the payment. It may be only.
