Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a work-specific manufacturing information management system, and in particular, to a production shop that needs to refer to, update, and store work-specific manufacturing information unique to each work. The manufacturing information management system by work.

[Conventional technology]

In the conventional production shop of this kind, refer to the manufacturing information for each work on a recording medium such as a floppy disk,
It was done by updating and accessing the storage medium.

[Problems to be solved by the invention]

In the conventional work-by-work production information management method described above, since work-by-work production information is stored in a single recording medium, data cannot be restored if the recording medium is damaged, and a large amount of work-by-work production information is statistically processed. There was a drawback that it was difficult to do.

[Means for solving problems]

The manufacturing information management system according to the present invention uses the product name, lot N
Production that requires work-specific manufacturing information consisting of work standard information such as o., serial number, and standard value, and work-specific information that is additionally updated in the manufacturing inspection process in the manufacturing inspection process or quality assurance after shipping. In the shop, means for installing a terminal device equipped with an IC card reading / writing section that can communicate with the production control computer in the preparation process and the manufacturing inspection process, and the work reference information is input from the terminal device in the preparation process to handle the work. Means for writing in the IC card, a means for transmitting and storing the work reference information from the terminal device to the production control computer in the preparation process, and a work for each work in the IC card corresponding to the work in the manufacturing inspection process. Means for referencing manufacturing information and stored in the production control computer in the manufacturing inspection process Means for referring to the manufacturing information for each talk from the terminal device by communication, means for writing the work-specific information generated in the manufacturing inspection process to the IC card corresponding to the work from the terminal device, and the work-specific information generated in the manufacturing inspection process. Means for transmitting from the terminal device to the production control computer for storage, and work-specific manufacturing information stored in an IC card corresponding to the work in the manufacturing inspection process, read from the terminal and transmitted to the production control computer for storage. And a means for transmitting the manufacturing-specific manufacturing information stored in the production control computer to the terminal device and writing the information in the IC card in the manufacturing inspection process.

〔Example〕

Next, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a system configuration diagram showing a network of a production system according to an embodiment of the present invention. The devices 2 to 5 can communicate with a production control computer 1 through a local area network (LAN) 8 and are connected to the devices 2 to 5. Is connected to an IC card reader / writer 6 so that information stored in the IC card 7 can be read and written from the devices 2 to 5.

FIG. 2 is a process block diagram showing an embodiment of the present invention, and FIG.
The figure is a flow chart showing an embodiment of a data processing system according to the present invention. A production shop 41 is composed of three steps of a preparation step 11, a step 12 and a step 13, and a work 31, a part 32 and a part 33 are provided in the production shop 41. When it is input, the preparation process 11, the process 12, and the process 13 proceed in this order, and when the final process 13 passes the inspection, the product is shipped. If it is judged from the inspection result of each process that it is necessary to return to the process before the process, the buffer 21 of the process 12 and the process 13
The buffer 22 is returned as a reconstructed product.

When a work is input to the preparation process 11, initial work-specific manufacturing information (model, manufacturing serial number, product name, order, lot No., input date, standard value, part data, etc.) corresponding to the work is stored in the device 2 Write to the IC card 7 from any one of 5 to 5.

Next, the work is put in step 12 together with the IC card 7 in which the work-specific manufacturing information is stored. In step 12, the IC card 7 is set in the IC card reader / writer 6 of the apparatus, the stored manufacturing information for each work is extracted, and then the work 31 is processed and inspected based on this.

The work which passed the standard as a result of the inspection has the process inspection data I
Write on C card 7 and production control computer 1
Then, it is sent to the step 13 together with the IC card 7. If it is determined that the work that does not satisfy the standard as a result of the inspection can be regenerated, it is returned to the pre-process buffer 21. The work judged to be unreproducible is discarded, and at the same time, the information is transmitted to the production control computer 1 and written in the corresponding area of the manufacturing information for each work.

The work sent to the process 13 and passed the final inspection is shipped from the shop, and the process information is transmitted to the production control computer 1.

FIG. 4 shows an example of the manufacturing information format for each work.
Manufacturing information for each workpiece Each item is stored in a matrix format with a fixed length of 10 bytes. The first column is the product type, the second column is the standard value, the third column is the part data, and the fourth column is the process. 1
The inspection data of step 2 and the inspection data of step 13 are stored in the fifth column. The 8th line is a pass / fail judgment flag, and the inspection pass / fail results of parts and each process can be recorded up to 10 times including the result of rework.

〔The invention's effect〕

As described above, the work-specific manufacturing information management system of the present invention has a plurality of registration media, which are IC cards and a production control computer, for storing work-specific manufacturing information unique to each work. I want to refer to
It is possible to read from the C card, and it is possible to inquire the production control computer even if the IC card is damaged. Further, even when the communication with the production control computer is impossible, the production can be continued only by the IC card, and the data of the IC card can be collectively sent to the production control computer when the communication is restored. Further, since the production control computer centrally manages the work-specific manufacturing information of each work, there is an effect that the statistical analysis processing of the quality assurance data can be easily performed.
