Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a process control system for manufacturing processes. Generally, when manufacturing components such as electronic components and mechanical components, the same components are often manufactured as one lot in order to perform efficient manufacturing.

In order to efficiently manage the progress of the manufacturing process, the progress status of the process is input to a computer,
In many cases, progress management is performed by a computer. However, in the case of manufacturing products in lot units, if one product in the lot fails, the whole lot will be stalled due to the repair.

There is a demand for a process control system capable of efficiently performing the process control of the manufacturing process.

2. Description of the Related Art FIG. 6 is a diagram for explaining a conventional example. For example, an electronic device and a communication device are composed of a plurality of printed board packages (hereinafter referred to as printed boards), in which the same kind of printed boards are often used.

Therefore, the same type of printed boards that compose one apparatus is manufactured as one lot. FIG. 6 shows an example of such a printed board manufacturing line. In the figure, 20a is a processing device 22, a progress management file 25a,
A product management system including a terminal 26a, and 33 is an input device such as a keyboard for data input, which is provided for each process.

The frame below the input device 33 in each process is 1
The same type of printed boards manufactured as one lot (the same alphabet indicates the same type of printed boards, and the numbers are the serial numbers of the same type of printed boards). A manufacturing instruction number (hereinafter referred to as a manufacturing number) is given to each lot, and each lot of the printed board is completed as a printed board by being processed through steps 1 to n. ..

In the figure, printed board A1 of serial number A1
A7 is in step 1, printed boards B1 and B2 of serial number B and printed boards C1 to C3 of serial number C are in step 2, and so on. Similarly, there are printed boards N1 to N5 of serial number N in step n. It is shown that.

In order to control the progress of the manufacturing process of the printed board as described above, when the process work is completed for each process, the worker inputs the product serial number from the input device 33, and the product management system 20a. Progress management file 2
The progress status is written in 5a to manage the progress.

In order to confirm the progress status of the process, a command is input from the terminal 26a to display the progress status of the designated manufacturing number on a display device or a printer (not shown).
To display and output.

[0010]

The above-mentioned conventional example has the following problems. -Since the completion information of each process is manually input from the input device, it takes man-hours for input and input errors occur.

When a failure occurs in a part of the printed boards in the lot, the entire lot becomes stagnant for repair. -If there is a delay in the high-priority manufacturing number for some reason when the same product mixes with the high-priority manufacturing number and the low-priority manufacturing number, the high-priority manufacturing number is pushed. ,
The process is confused.

When an express item occurs, it is difficult to deal with it.・ There may be leakage due to design change, which may lead to the next process. The present invention enables individual management by displaying a bar code on each product of a lot-produced product by a bar code printer and importing process progress information into a management system by a bar code reader, thereby performing priority processing. We try to realize a process control system that makes it possible.

FIG. 1 is a block diagram for explaining the principle of the present invention. In the figure, 10 is a manufacturing control system, 11 in the manufacturing control system 10 is a manufacturing command file in which a manufacturing command number output from a production management system (not shown) is written, and 12 is in the manufacturing command file 11. Is a priority processing file that designates the priority order of the manufacturing instruction numbers, 13 is a terminal that inputs a write / read command to the manufacturing instruction file 11 and the priority processing file 12, and 14 is a command from the terminal 13. It is a processing device that manages the manufacturing instruction and the progress status of the process.

Further, 20 is a product management system, 21 in the product management system 20 is a bar code file for fetching information from a bar code reader 32, and 22 is a processing device for collecting and managing process progress information. Is.

Further, 30 is a bar code input / output means, and the bar code input / output means 30 reads a bar code printer 31 for sticking a bar code label to each product P and a bar code label of each product P. When the product P is manufactured by the bar code reader 32, the priority processing file 1 is sent from the terminal 13 of the manufacturing management system 10 to the manufacturing command number which is required to be manufactured preferentially.
By writing the manufacturing instruction number for priority processing in 2, the manufacturing is performed with priority and the progress status is managed.

Further, the product management system 20 is provided with a priority processing file 23 having the same contents as the priority processing file 12 in the manufacturing management system 10, and the process progress status and priority processing of each product P inputted from the bar code reader 32. The file 23 is collated, and the product P whose process is progressing quickly is assigned to the manufacturing command number for which the priority process is designated.

Further, the design change file 24 is provided in the product management system 20, the contents of the design change file 24 are written in the bar code reader 32, and the bar code read by the bar code reader 32 is the design change file 24. If it matches the contents of, an alarm signal is generated.

[0018]

When manufacturing the product P, the higher-level production management system gives a serial number as a manufacturing instruction number to each lot, and gives a delivery date for each serial number.

The contents of this manufacturing instruction are applied to the manufacturing control system 1
0 is written in the manufacturing instruction file 11 and, for example, the same products P are arranged in order from the earliest delivery date. Here, in addition to the delivery date initially instructed by the production management system, when the process is rushed and a product number that requires priority processing occurs, the priority processing is performed from the terminal 13 of the manufacturing management system 10. By designating the production number to be performed and inputting the desired date of the express, the production number is written in the priority file 12.

With respect to the manufacturing number for which the priority process is designated, the manufacturing management system 10 prioritizes the surface alignment of the parts and inputs them to the manufacturing line. Further, since the bar code printer 31 individually writes the bar code to each product P, the bar code reader 32 reads the bar code each time the processing of each process is completed, and the product management system 20 operates. The process progress status is written in the barcode file 21.

Therefore, when a failure occurs in a part of the products P of the lot for which priority processing is designated, and when there are the same products P with different manufacturing numbers, the product whose process is advanced earlier among them. Automatically assign P to a product number for which priority processing is specified.

Further, by interlocking with a design system (not shown), the presence or absence of design change is written in the design change file 24 of the product management system 20 through the manufacturing management system 10. On the other hand, the same information is also held in the bar code reader 32, and when the bar code read by the bar code reader 32 matches the contents of the design change file 24, the product P in which the design change should be folded is included in the process. An alarm signal is generated when it is judged that it has flowed.

With such a configuration, priority processing as a lot and priority processing of individual products P can be performed, and leakage of design change can be surely prevented.
