Conventional process progress management methods generally used documents such as slips and cards attached to lots (product production units), so it was necessary to search for work slips for each work process and enter the work results. In order to analyze working conditions, it was necessary to enter actual work results into a computer system.

Therefore, there are problems in that productivity decreases due to an increase in work preparation time and the occurrence of incorrect work, and that it takes too many man-hours to collect and organize data for analyzing work conditions.

In addition, in the centralized process progress management method using a single central computer, all terminals for collecting actual work instructions in each work process were centrally managed.
As the scale of the system increases, it may be difficult to ensure quick response, or the system may be expanded (e.g., by adding automatic control functions to terminals), combined with other systems, or horizontally deployed to other workplaces. Another problem was that improving and expanding the Nau system required a large amount of development man-hours and investment.

[Purpose of the invention]

The purpose of the present invention is to eliminate the above-mentioned drawbacks of the prior art, and to make it possible to repeatedly use the same type of equipment in multiple work processes for multiple products, and to change the work conditions for each production unit (lot). On the production line, the system's scalability, reliability, performance, developability, and
For improved maintainability and resources, read and
An object of the present invention is to provide a process progress management device using a writable recording medium as a lot attachment slip.

As a result, the identification data recorded on the magnetic card 10 is sent to the control device (for example, a microcomputer with a tactile input CRT) 1 for managing work execution units in the control process CONT via the transceiver TR of the local area network 5. etc. will be sent.

This control device 1 for managing work execution units performs data exchange, work instructions (procedures), and device control in a plurality of subsequent work execution units WP. Then, process tracking is performed from the transmitted identification data, and the product name, lot number, and process name are checked in order to confirm the work in the work execution unit WP, and the results are sent to the control device 1 and the display device with input function. (For example, a tactile CRT) 4. After confirmation, the pre-registered product
While guiding the work according to the work procedure control program for each process, the actual work results are collected and the inspection device 3 is controlled.

That is, the control device 1 and display device with input function 4 input registration information of the worker's name (for example, number) before starting the work, and select the corresponding work procedure control program from the process tracking (for example, file). In addition to calculating work conditions and displaying various work contents, it also controls inspection work online and collects actual work results.

After that, by comparing the work results and the work judgment standards, whether or not to advance the lot to the next process, or if proceeding, the work conditions for the next process are set and the control device 1 and the display device with input function 4 indicate. Furthermore, process tracking is processed, necessary information is transmitted to the magnetic card reading/recording device 2 via the transceiver TR of the local area network 5, and information on the magnetic card 10 is updated. At the same time, work performance data in the relevant work process is transmitted together with identification data to a processing device (for example, a desktop computer) 6 for managing performance data via the transceiver TR of the local area network 5.

The transmitted performance data is immediately registered in the memory (e.g. magnetic disk) 7 in the data collection unit CENT, processed into various data as necessary, and displayed on the display device (e.g. console CRT) 8 and recorded. equipment (e.g. printer)
