Description

  The present invention relates to a product delivery matching method and a product delivery matching system in which a product is created and delivered based on an electronic electronic drawing.

  Conventionally, a request for production of custom-made parts, etc. is sent to the partner company (for example, a partner company) by FAX etc., and the partner creates parts etc. based on the received drawing and the creation is completed. A slip is attached to the completed parts and sent to the original requester. The requester performs inventory management based on the slip attached to the sent parts and the like, and issues the parts and the like as needed.

Also, there is a technique for attaching a tag in which a hash value of the electronic drawing is written to the electronic drawing, comparing the tag attached to the copied electronic drawing, and determining the authenticity of the electronic drawings (Patent Document 1). ).
JP 2001-195306 A

  In the former mentioned above, inventory management was performed based on the slips attached to the parts produced by requesting production of parts, etc. based on the drawings, and the goods were issued upon request. There was a problem that a lot of mistakes occurred in the custom-made products with slightly different items.

  In the latter case, the original electronic drawing and the copied electronic drawing are compared to check the authenticity of the original electronic drawing (check that it has not been altered in the middle). As described above, there is a problem that it cannot be applied to prevent an error from occurring when a part having a slightly different shape or the like is delivered.

  In order to solve these problems, the present invention stores the eigenvalue A generated from the electronic drawing at the request source, sends the electronic drawing to the request destination, and the parts created based on the electronic drawing at the request destination. The IC tag with the unique value H generated from the electronic drawing is attached to the requester and delivered to the requester, etc., and the stored unique value A is compared with the unique value H read from the IC tag at the time of delivery. Like to do.

  According to the present invention, when the eigenvalue A generated and stored from the electronic drawing at the time of the request matches the eigenvalue H read from the IC tag in which the eigenvalue H generated from the electronic drawing at the request destination is written, Thus, it is possible to completely prevent an erroneous delivery of a part or the like having a slightly different shape, such as a custom-made product created from an electronic drawing.

  The present invention stores the eigenvalue A generated from the electronic drawing at the requesting source, sends the electronic drawing to the requesting destination, and generates the eigenvalue generated from the electronic drawing at the requesting part based on the electronic drawing. A part that is attached to an IC tag with H written and delivered to the requester, etc., and is stored when the stored unique value A is compared with the unique value H read from the IC tag, and created from the electronic drawing. It was possible to completely prevent mistakes such as leaving.

FIG. 1 shows a system configuration diagram of the present invention.
In FIG. 1, an order drawing management system 1 is connected to a network 21 and manages drawings (electronic drawings) of products (parts etc.) for which an order has been received, and manages products created based on the electronic drawings. Here, the drawing input means 2, the processing unit 3, the electronic drawing DB 6, the IC tag reader / writer 7, the product 81, the IC tag 91, the output unit 10 and the like are illustrated.

  The drawing input means 2 inputs a drawing for creating a product and stores it in the electronic drawing DB 6.

Next, the operation of the configuration of FIG. 1 will be described in detail according to the order of the flowchart of FIG.
FIG. 2 shows a flowchart for explaining the operation of the present invention. The order drawing management system 1 and the process management system 11 in the figure correspond to the order drawing management system 1 and the process management system 11 in FIG.

  (1) A procedure for receiving a request for manufacturing by receiving a drawing of a custom-made product from a customer, sending an electronic drawing to the manufacturer, and requesting the manufacturing will be described in detail.

In FIG. 2, S1 receives a drawing from a customer by FAX.
In S2, an order drawing from FAX is input. This reads the drawing requested for creation (order drawing, bitmap data, etc.) received from the customer via the line in S1.

  In S3, the drawing is stored as a bitmap or the like. This is an electronic drawing of a drawing request received from a customer in S1 to S2 in the form of a file such as a bitmap or the like (in the case of FAX reception or e-mail reception) or CAD data (in the case of e-mail reception). Store in DB6.

  In S4, an instruction to create a custom-made product is given. This instructs the process management system 11 in the factory to create an electronic drawing stored in the electronic drawing DB 6 via the network 21.

  In S5, a hash calculation is performed on the drawing information. This is to calculate the hash value A (unique value A) based on a predetermined value for the electronic drawing created instructed in S4, create a record shown in FIG. A (eigenvalue A) is set as shown and stored in the electronic drawing DB 6 (stored in association with the electronic drawing and product information).

  Through the above S1 to S5, the drawing of the special order received from the customer is stored in the electronic drawing DB 6 as an electronic drawing, and the creation instruction and the hash generated from the electronic drawing are sent to the process management system 11 of the relevant factory via the network 21. The eigenvalue information record shown in FIG. 4A in which the value A is set can be created and stored in the electronic drawing DB 6. As a result, an instruction to create an electronic drawing of the ordered custom-made product is given to the production site, and the hash value H (the electronic value used at the time of manufacture) read from the IC tag 91 attached to the product 81 when the delivered product 81 is delivered. The preparation for matching with the hash value H) created from the drawing is completed.

  (2) The procedure for creating and delivering a product (custom product) based on the electronic drawing on the side receiving the manufacturing request in (1) will be described in detail.

  In FIG. 2, S11 determines whether it is a creation instruction. In step S4 described above, it is determined whether there is an instruction to create a custom-made product. If YES, the process proceeds to S12. If NO, repeat S11.

  In S12, it is determined that there is a creation instruction in YES of S11. Therefore, the electronic drawing having the creation instruction is obtained (downloaded) from the electronic drawing DB 6 via the network 21, and stored in the electronic drawing DB 14.

  S13 notifies the creation process and contents to the line. This notifies the line (the department in charge of the factory) of the process of creating a custom-made product (product) to be created with the electronic drawing obtained in S12.

  In step S14, it is determined whether the creation of the custom-made product is completed. In the case of YES, since it has been found that the creation of the special order product (product) notified in S13 is completed, the process proceeds to S15. In the case of NO, S14 is repeatedly monitored.

  In S15, since it is determined that the creation of the custom-made product is completed in YES of S14, the creation completion is reported.

  In S16, the drawing information is hashed and written in the IC tag 9. This is because the creation of the custom-made product 8 is completed, the hash value H is created from the electronic drawing used when creating the custom-made product 8 and written in the IC tag 9 (the IC tag information of FIG. Write).

  In S17, a delivery report is made. In this case, the custom-made product (product) 8 to which the IC tag 9 having the hash value H written in S16 is attached is delivered to the requesting source (or designated destination) and a delivery report is made.

  Through the above-described S11 to S17, the electronic drawing of the special order product (product) 8 created based on the electronic drawing of the instructed special order product on the side (factory side) that received the special order product creation instruction from the manufacturing requester. It is possible to affix the IC tag 9 with the hash value H generated from, and deliver a custom product (product) 8 with the IC tag 9 affixed to a manufacturing requester or the like.

  (3) A detailed description will be given of the operation when the custom-made product (product) 8 to which the IC tag 9 is attached in (2) is delivered at the manufacturer requesting delivery.

  In FIG. 2, S6 determines whether or not the product has been delivered. This is determined, for example, by the manufacturing requester who received the delivery report in S17 of FIG. 2 described above, and whether or not the custom-made product (product) 8 to which the IC tag 9 is actually attached has been delivered. If YES, the process proceeds to S7. If NO, repeat S6.

  In S7, since it is determined that the custom-made product 8 with the IC tag 9 attached is delivered in YES in S6, information is read from the IC tag of the custom-made product. This reads tag information from the IC tag 91 affixed to the delivered custom-made item 81 (for example, reads the IC tag information of FIG. 4B).

  In step S8, the tag information and the eigenvalue A are matched to determine whether they match. This is the eigenvalue H (hash value H) in the IC tag information of FIG. 4B read from the IC tag 91 affixed to the delivered product 81, and the electronic drawing at the time of manufacturing instruction in S5 described above. Are compared with the eigenvalue A (hash value A) that has been created and stored. In the case of YES, the unique value A created from the electronic drawing at the time of creation instruction matches the unique value H read from the IC tag 91 affixed to the custom-made product 8 created earlier at the creation instruction, and the requested electronic drawing Determine whether it is a custom-made product made in step 1. In the case of YES, the eigenvalue A matches the eigenvalue H read from the IC tag 91 affixed to the custom-made product, and it is found that the product is a custom-made product created from the same electronic drawing. . On the other hand, in the case of NO, no exit instruction is issued.

  Through the above-described S6 to S9, the unique value A (for example, the hash value A) created by the creation instruction source from the electronic drawing instructed for creation, and the unique value H (for example, the hash value H) read from the IC tag attached to the product (product) The unique value H (for example, the hash value H) created from the electronic drawing used at the manufacturing site and written in the IC tag matches, so that the product created from which electronic drawing is surely It is easy to check, especially when there are many custom-made products (special products that differ only in part of standard products) to be created from the drawing. It will be possible to leave the store without fail.

  FIG. 3 shows an example of an electronic drawing of the present invention. The illustrated electronic drawing shows a custom-made drawing image made up of bitmap data of a custom-made product (product) received from a customer by FAX in S1 and S2 of FIG. 2, and a top view of (a), It consists of a side view and a three-side view of the bottom view of (c). This electronic drawing is a custom-made machine part “pulley” whose diameter (inner diameter, outer diameter, etc.) varies slightly depending on the customer, and the name is “pulley”. The ID (product number) given to the name is very difficult to confirm the matching between the electronic drawing and the custom-made product “pulley” actually created, and many errors have occurred.

  Therefore, in the present invention, the eigenvalue A (hash value A) created from the electronic drawing instructed in S4 and S5 in FIG. 2 and the eigenvalue created from the electronic drawing used in the field when the custom-made product “pulley” is manufactured. H (hash value H) is written in the IC tag attached to the custom-made product “pulley” at the site, and the unique value H read from the IC tag 91 attached to the custom-made product “pulley” at the time of delivery and the electronic drawing By issuing a shipping instruction when matching with the eigenvalue A stored in correspondence with (or created from an electronic drawing), it is ensured in the case of a custom-made product with the same product name and slightly different shape. It is possible to issue a delivery instruction after confirming that the product is a custom-made product that matches the drawing ordered.
