Description

Detailed Description of the Invention [Field of Application of the Invention] The present invention relates to a production system for producing many types of products, and particularly to a work instruction device that is suitable for taking countermeasures in immediate response to production fluctuations. Regarding.

[Background of the invention]

As disclosed in, for example, Japanese Patent Application Laid-Open No. 58-201105, the conventional device collects work instructions or work results at one production site. This was realized using a system that was constructed with nine parts.

This conventional apparatus has an economical problem in that a microcomputer must be installed in each production facility. Therefore, it is conceivable to manage a plurality of production equipment units using a single microcomputer.

However, in this case, the worker has to go back and forth between the production equipment unit and the microcomputer many times in order to receive work instructions from the microcomputer or input work results. A problem arises in terms of operability.

[Purpose of the invention]

The purpose of the present invention is to eliminate the problems of the prior art, automatically issue instructions for the next work in response to the work progress of production equipment, and
To provide a work instruction device suitable for shortening work idle time, work delay time, etc.

(Summary of the Invention) In the present invention, the second microcomputers installed in each of a plurality of production facilities are managed by one first microcomputer, and the terminals of the six second microcomputers are managed by the units of the corresponding production facilities. It solves the problems of economic efficiency and operability that were not carefully considered with conventional equipment.

Examples of L invention] Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

7t program processing method J11- is a diagram.

In FIG. 1, reference numeral 1 denotes a progress management station microcomputer (WLl's My Ya Combi-ta), which automatically instructs a VC'sL plan and a production schedule for one day's worth of products according to a one-day cycle, for example.

Code 2 is several production equipment (hereinafter referred to as work unit)
The figure shows the work unit microcomputer (second microcomputer) installed at each location.

Work instructions and performance collection are managed according to the program shown in Figure 3. Reference numerals 7, . . . are work units installed for each unit of production equipment, and for example, according to the program shown in FIG. Completed etc! ! Enter your grades. Reference numeral 6 denotes a wireless modem, which is used to wirelessly establish a connection via data communication with the microcomputer 2 and the microcomputer 2 and the progress management station Migrocomputer 1. 22 microcomputers for each work 2...are local area network communication control device 5. l'FQ axis cable 4. terminating resistor 5
Data communication between each microcomputer is performed by a local area network consisting of The required number of machines will be installed accordingly. In the example shown in FIG. 1, two working unit microcomputers 2 and seven working unit microcomputers 7 are installed.

As shown in FIG. 2, the working unit call terminal 7 has, for example, a wireless modem 71. Antenna 72. Printer 73, liquid crystal display 75. Power supply switch 6° work request key 77,
Work display key 781 Work start 1,000-799 Work completion key 8
0. An end key 811 and a screen scroll key 82 are provided. This work station 7 has a dedicated device for the worker, who inputs the work performance information when starting work and 791 work completion key QO Eri, and displays the work instruction information on the liquid crystal display 75. Output from printer 73.

In order to manually confirm the contents of the work instructions using the work unit ``77'', and manually select the ``1a'' that indicates ``start of work'' and ``completion of work'', the worker must first turn on the power switch 61! -Press (on) to launch the program tX stored in mK, then work 1! *1000-y71 (Press (on)) At the timing of this press, a work request message is sent to the 2-Y2 Tomiguro Combi and 2-Y2 via the wireless modem 71 and antenna 72.

By receiving this message, you can select the appropriate work data and send it to us in one batch. The work data received through this procedure is stored in the internal memory of the work end yg7.All subsequent work instructions are output based on the contents of this memory6.For example, work When starting work, the contents of the work data are displayed on the liquid crystal display 75 by pressing (on) the work display key 77.6 The worker can scroll the screen over this display content by pressing ?-82'i to display the work data to be started. The corresponding work data is displayed at a predetermined position, for example, on the first line of the display screen.Then, by pressing (on) Work Start=?-79'j, the corresponding work becomes the work start state.At this time, the corresponding work Among the data contents, for example, the time at which -79 was pressed for work start is recorded as the work start actual time, the work status is updated to work etc., and the same data is sent to the work unit 9 microcomputer 2. When the work is completed, by pressing Work Complete = P-801, the corresponding work data in the work rower stored in the memory becomes the work completed state.At this time, among the contents of the corresponding work data, for example, the work completed The pressing time of WORK COMPLETE -?-80 is recorded as the actual time f'L, the work status is updated to WORK COMPLETE, etc., and the same data is sent to the work unit microcomputer 2.

When the day's work is finished, etc., the worker presses the end key 8.
By pressing 1, online connection between the work unit Migro Computer 2 and the work unit Cape Toendo Song 7 can be established.
w Cut.

Incidentally, when the work is requested, when the work is started, when the work is completed, when the sVC is pressed, and when the end key is pressed, the sVC is sent to the printer 73 and the history is recorded on the printer paper 74.

〔Effect of the invention〕

According to the present invention, work instructions that immediately respond to the work progress status in each production facility are realized using the Migro computer Nanten as a medium, thereby minimizing work idle time, work delay time, etc. in one work! ! This is effective in improving the accuracy of results.
