The CPU 3 reads the data stored in the manufacturing priority order memory section and the manufactured item processing procedure memory section of the RAM 5, and stores the workers and lot numbers in the work data memory section according to the work order of the manufactured item to be manufactured with priority. to be memorized. At this time, the previous work completion sign is stored in the work completion sign area corresponding to the first-rank worker among the workers who carry out the work for each lot number of each manufacturing item.

Further, the CPU 3 detects the worker name of the worker who is to start the work via the input device 7, and selects the possessed skills stored in the worker data memory unit corresponding to the worker name. It is configured to read and store. Roughly, the CPU 3 retrieves the work being processed from the work data memory section of the RAM 5, reads out one worker who will be the next work after that work, according to the read priority order, and corresponds to the read worker. Necessary skills and functions are read out from the manufacturing item-specific processing procedure memory and stored.

The CPU 3 is configured to determine whether or not the necessary skills are included in the stored skills possessed by the worker, and if not included, read out the next ranked worker from the work data memory section. Roughly speaking, the CPU 3 reads out the functions possessed by the sewing machine that are not used in the order of the machine number from the machine data memory section of the RAM 5, sequentially determines and selects whether or not the stored necessary functions are included. The timer is configured to read out the worker of the next rank.

C, PU3 visually displays the memorized operator, the corresponding manufacturing item and lot number on the liquid crystal display device 2a of the terminal device 2 via the communication device 9, and displays the selected machine number on the terminal device. It is configured to visually display on the second liquid crystal display device 2a. Further, the CPU 3 is configured to store an in-use sign corresponding to the machine number in the machine data memory section, and to store a machining in-progress sign corresponding to the worker in the work data memory section. In this way, the worker and the sewing machine to be used are photographed by the worker, and the sewing work is started.

In addition, CPtJ3 waits until the end of the 10th work is completed and a termination signal is generated from the terminal device 2, and when the signal ∆ is generated, the sewing machine in which the terminal device 2 is installed is activated. The in-use sign in the machine data memory section is erased in correspondence with the number. moreover,
CPtJ3 erases the corresponding 1-in-process sign in the work data memory section, stores the processed sign, and at the same time stores the previous work sign corresponding to the next worker, and performs the above-mentioned allocation work. The CPLJ 3 stores the actual number of sewing pieces produced based on the end signal input from each terminal 2 from time to time, and stores the sewing results in a predetermined storage area of the RAM 5 and the external storage device 6. It is designed to be stored in

Thereafter, each time the termination signal is generated from each terminal device 2, the CPU 3 determines the operator, the machine number and lot number used, and the terminal device 2 from which the termination signal was generated among the terminal devices 2 and its machine number. It is configured to be visually displayed on the liquid crystal display device 2a of the terminal device 2 of the sewing machine marked with.

The operation of the work command system configured as above is described in the eighth section.
The explanation will be given according to the flowchart shown in the figure.

Now, by operating the input device 7 in advance, the worker data memory section of the RAM 5 stores the worker's name and skill level data, and the machine data memory section stores the machine number and its functions. . Further, the worker group memory section stores worker names for each group, and the manufacturing priority memory section stores manufacturing items such as shirts and other clothing.
Data representing the manufacturing priority determined for each item and the lot number of parts divided for each item are stored, and the processing procedure memory section for each manufacturing item is used to process the manufacturing items such as shirts. Data representing the required workers, the processing order in which they perform the work, the necessary skills and machine functions necessary to perform the work is stored.

In the work data, various types of signs such as a pre-work completed sign, a processed sign, and a process-in-progress sign are stored corresponding to each work according to the state of the work being performed at that time. Now, when the end signal is input from the terminal device 2 to the CPU 3 (step 1, hereinafter step is represented by S),
Based on the end signal, the CPU 3 releases the protection so that the next work process can be read from the RAM 5, and then
The work process currently being worked (processed) stored in the work data memory unit is searched based on 19 in progress, and the next work process of the searched work process and the previous work completed sign are completed, and A further search is made for a work process that does not have a processing in progress sign and a processed number in (S2).

In S3, the CPU 3 determines whether or not there is a work process that can be started from among the searched next works based on the data stored in the work data memory section, and if not, reads out the next process in S9, The same process is performed in S3. S3
When it is determined that there is a next work that can be started, S4
In the next step, check the optimal conditions such as skills and necessary functions required for the next work (for example, conditions based on thread, skill level, transportation loss, etc.), and if there are no optimal conditions, S
Step 8 reads the next work candidate, performs the same process at step S4, and RAs all the checked next work candidates.
It is stored in a predetermined storage area of M5.

Then, in S5, the optimal next work process is selected based on the checked optimal conditions among the next works stored in the RAM 5, and the next work process is selected so that instructions for the next work process other than the selected optimal next work process are not issued. The work is protected (S6). Further, the CPU 3 transmits the selected work instruction data, that is, data such as the work process, machine number (that is, terminal number), lot number, etc., to the terminal device 2 that outputs the end signal (S7). When transmitted to the terminal device 2, the CF) L12 stores the transmitted data and the name of the worker who gave the work command in the operation memory section of the external storage device 6, and also records the command time when the work command was given. The information is stored with reference to the clock 11 (S8).

On the other hand, the terminal device 2 stores the transmitted work instruction data in a buffer, displays the optimal work instruction stored in the buffer on the liquid crystal display device 2a, and issues a work instruction.

Also, when the end of printing No. 18 is generated, the CPU 3 detects the machine number 1 of the sewing machine 10 in which the terminal device 2 is installed based on the end signal, and detects the machine number corresponding to the machine number in the machine data memory section. Delete the in-use sign corresponding to the worker in the work data memory section, memorize the processed 4 twins, and display the previous work corresponding to the worker next to that worker. Memorize the signature.

Next, the case where the system goes down will be explained according to the flowchart of FIG.

Now, if for some reason the power supply voltage of the work command system drops and the system goes down, CPU3's R
Various data in AM5 are erased, but at this time, various data in external storage device G is stored as is.

After the power supply voltage of the work command system is applied to the normal voltage again, the input device 7 is set to the recovery mode, and when today's date, current time, and worker name in the line are input, the CPLI 3 The data is stored in the RAM 5 and each corresponding memory section of the external storage device 6 (S11). Next, the CPU 3 transfers the contents of the work data memory section of the external storage device 6 to the work data memory section of the RAM 5. Similarly, the CPLI 3 is a worker data memory section of the external storage device 6;
The contents of the memory section having the same memory map as the machine data memory section, manufacturing priority order memory section, and manufactured item machining procedure memory section are transferred to the corresponding memory sections of the RAM 5 (S
12).

Next, in step 813, the CPtJ3 reads the commanded work data and the performance data from the operation memory section and the performance data memory section of the external storage device 6, one by one, in the order of the time in which they were stored, starting from the beginning of the day. And CPU3 is 8
In step S14, the performance data is aggregated for each N product, and in S15, the performance data is aggregated for each worker. Subsequently, the CPU 3 re-executes the processing from the start of the work day based on the instructed work data read from the operator memory section (316).

Then, in 817, the CPU 3 determines that the time when the work instruction data corresponding to the command performance work data is output to the terminal device 2 (that is, the time recorded in the external storage device 6, hereinafter referred to as the execution time again) is due to a drop in the power supply voltage. Determine whether it is time. Note that the power supply voltage drop time coincides with the re-execution time of the last instructed work data stored in the operation memory section. If the CPU 3 determines that they do not match in step 817, the process returns to step S13, reads one data item each from the operation memory section and the actual data memory section of the external storage device 6, and repeats the loop from 314 onwards. 81
If the CPU 3 determines YES at step 7, then it returns C at step 818.
The PU3 transmits work instruction data corresponding to the work being performed during the power supply voltage drop time, such as work process, machine number (i.e., terminal number), lot number, etc., to the terminal device 2 that outputs the end signal. At the same time, the recovery mode is shifted to the normal control program shown in FIG.

When the data is transmitted to the terminal device 2, the terminal device 2 stores the transmitted work instruction data in a buffer, and visually displays the work instructions stored in the buffer on the liquid crystal display device 2a.

In addition, this invention is based on the above-mentioned actual 7Jl! The present invention is not limited to the examples, and may be arbitrarily modified without departing from the spirit of the present invention.

(Effects of the Invention) As detailed above, this invention restores various data up to the time of system down when the system power goes out during processing work due to natural or man-made disasters, or when the system goes down due to unavoidable trouble. This has an excellent effect in that work instructions for recovery work and system redisclosure can be given at an early stage.

Furthermore, the present system can be used not only for sewing components of clothing such as shirts, but also for fabricating N-covers of shoes, gluing soles of shoes, etc.
