Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a work command system in a factory, mainly a garment factory.

(Prior art) Conventionally, in a work system in a III manufacturing factory, a work process analysis table was created by a person to instruct the next processing work after a machining work was completed, and the created work process analysis table was centralized. has been done. For example, a work process analysis table for shirts is created with a single pattern of work order as shown in FIG. J3, the number attached to the left of each work step represents the time (seconds) required for that step.

(Problem to be solved by the invention) Therefore, in the past, even when one machining operation was completed, the order of the operations was uniquely determined, which made it possible to respond flexibly and reduce the amount of time on hand. There was a problem that the work balance was sometimes poor and the equipment could not be used effectively.

(Purpose) This defense was made in order to solve the above-mentioned problems of the conventional method. The goal is to provide a system.

(Means for Solving Problem B, Lawn) This invention allows workers to operate a large number of working machines installed in a factory to produce products separately, so that workers who have completed a processing task are assigned the next processing task. In a work command system in a factory, when one production item is produced by division of labor, the normal start order of each processing work sequentially performed in the division of labor production is memorized, and one processing work in the normal start order is memorized. When there is another machining operation that can be carried out next, storage means for storing a branch start order branching from the above-mentioned machining operation, and a storage means for storing a branch start order branching from the above-mentioned processing operation, and a storage means for storing a branch start order branching from the above-mentioned normal start order and the branch start order at the end of the processing operation at which the branch start order diverges. a retrieval means for retrieving one machining operation from the storage means that is the next machining operation in the normal start order and the branch start order and that can be performed by the working machine and the worker in the idle state; command means for instructing the worker to perform the processing work;
The gist of the present invention is to include a switching means that uses the normal start order or branch start order to which the searched machining work belongs as a reference for subsequent work commands.

(Function) In each processing operation performed sequentially in division of labor production, the search means searches for the next processing in the normal start order and the branch start order, depending on the end of the processing operation in which the normal start order and the branch start order diverge. One processing operation that can be performed by a working machine and an operator in a working and idle state is retrieved from the storage means. Then, the command means commands the retrieved machining work to the worker in the idle state. Further, the switching means uses the normal start order or branch start order to which the retrieved machining work belongs as a reference for subsequent work commands.

(Example) An example in which the present invention is embodied in a work command system for a garment factory will be described below with reference to FIGS. 1 to 13.

A wide variety of sewing machines (not shown) are installed in the sewing factory, and each sewing machine is assigned a machine number and a terminal device 2 is installed. Each terminal 2 is connected to an AL control unit 3, and each terminal 2 has an end switch and a liquid crystal display (
(both not shown) are installed respectively. Furthermore, the terminal device 2 leaks a central processing charge illumination device and a buffer for the terminal device, and the same buffer I is adapted to store the arc from the control unit 3. Then, when an end signal is output to the central processing control unit by turning on the end switch i) i'J, the data in the buffer in the terminal is visually displayed on the liquid crystal display device. The central processing control unit is configured such that the sewing machine on which the terminal PA2 is installed starts a predetermined i-making work and outputs a work instruction request signal before the scheduled time when the work is finished.

Control unit (hereinafter referred to as CI) consisting of a central processing control unit as a search means, command means, and switching means tJ
) is a continuous read only memory (hereinafter referred to as ROM) 4 that stores various control programs, and a continuous writeable memory (hereinafter referred to as RA) that stores the temporary performance results.
M) 5, and is connected to an external storage device 6 as a storage means for storing input data from an input device 7 and various data created and edited by the CPU 3. . The external storage device 6 includes various memory sections such as a worker data memory section, a machine data memory section, a manufacturing layer prior order memory section, a manufactured item processing procedure memory section, a next work candidate data memory section, and a work data memory section. It is equipped with

The worker data memory section is adapted to store worker data representing worker names and skills possessed by each worker, as shown in the diagram in FIG. As shown in the memory map of FIG. 3, the machine data memory section stores the machine number, the functions possessed by each sewing machine, and data representing an in-use sign indicating the usage status of the sewing machine.

Made'? i fQ Priority Order Memo County As shown in the memory map in Figure 4, for example, the manufacturing items of clothing such as shirts, the manufacturing priority determined for each item, and the lot numbers of parts divided for each item are stored. It stores the data it represents.

As shown in the memory map in Figure 5, the processing procedure memory section for each manufacturing item stores information about the processing workers required to manufacture the manufacturing item such as a shirt (e.g., 8-piece bracelet, placket, buttonhole stitching, etc.). , a processing worker is simply referred to as an "operator"), the order in which the work is usually started, and the necessary skills and functions of the machine required to perform the work. As shown in the memory map of FIG. 6, the next work candidate data memory section stores workers (for example,
8 pasting bracelets, placket attachment, buttonhole stitching, etc.), and when the prescribed work process is completed, the next work will be done by the next worker.
For example, the next worker for ``8-piece bracelet'' is ``putting on a placket,'' and the next worker for ``with placket'' is ``buttonhole stitching.''
The next worker after "buttonhole stitching" will be "pocketed" and the next worker after "pocket opening sewing" will be "pocketed"), and each worker's next task will be memorized. The one located on the left side of FIG. 6 is read out preferentially.

As shown in the memory map of FIG. 7, the work data memory section stores the manufactured item, the lot number, the worker, a pre-work completed sign indicating whether or not the work can be started, and the status of the work being performed. Based on the data transmitted from the terminal device 2, data representing a processing sign indicating whether the work has been completed and a processed sign indicating whether the work has already been completed are respectively stored. .

An input device 7 consisting of a keyboard is connected to the CPU 3,
By inputting the provided keys, data of the worker, etc. is stored in each memory section of the external storage device 6. Further, the human-powered device 7 is equipped with a cursor movement key (not shown), and by operating the key, the display device 8 connected to the CPU 3 together with the input device 7 is displayed.
The CPU 3 is configured to display and control a cursor on the screen of the CPU 3, and to display data output from the CPU 3. The communication device 9 is configured to transmit data output from the CPLJ 3 to each terminal device 2.

The CPU 3 reads the data 1aQ recorded in the manufacturing priority order memory section and the manufacturing item processing procedure memory section, and stores the workers and lot numbers in the work data memory section according to the work order of the manufacturing item to be manufactured with priority. Make me remember. At this time, the previous work performance sign is stored in the area of the completed work sign corresponding to the first-ranked worker among the workers who carry out the work for each loft number of each manufactured product 1. .

Further, the CPLJ3 detects the worker name of the worker who is to start the work via the input \R position 7, and stores the worker name corresponding to the worker name stored in the worker data memory section. It is configured to read and store possessed skills. Roughly speaking, the CPU 3 searches the work data memory section for the work being processed by the worker, reads out one worker who can be the next work for that work from the next work candidate memory section according to the read priority order, and selects the next work candidate memory section. Necessary skills and functions corresponding to the read worker are read from the manufacturing item-specific processing procedure memory and stored.

The CPU 3 is configured to determine whether or not the necessary skill is included in the stored skills possessed by the worker, and if it is not included, to read out the worker of the next rank from the next work candidate memory section. . Further, the CP tJ 3 reads out the functions possessed by the sewing machine which are not used in the order of the machine number from the machine data memory section, sequentially determines and selects whether or not the stored necessary functions are included, and selects them if they are not included. is configured to read out the worker of the next rank.

The CPU 3 sends the stored workers, corresponding manufacturing items, and lot numbers to the terminal 2 via the communication device 9.
The selected machine number is visually displayed on the display device of the terminal device 2, and the selected machine number is visually displayed on the display device of the terminal device 2. Further, the CPLJ 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 N manufacturing work is started.

Also, CPtJ3 completes the 10 tasks and returns to the terminal 2.
Wait until a termination signal is generated from S2, and when that signal is generated, erase the in-use sign in the machine data memory section corresponding to the machine number of the sewing machine in which the terminal device 2 is installed. is configured to do so. moreover,
The CPLJ3 erases the corresponding processing sign in the seventh section of the work demonstrator, and stores the processed sign,
At the same time, it is configured to memorize the previous work number corresponding to the worker of the next rank and perform the above-mentioned allocation work.

Thereafter, each time the work instruction request signal is generated from each terminal P52, the CPtJ3 inputs the worker, machine number and lot number to the terminal device 2 from which the work instruction request signal was generated. The machine number is visually displayed on the display device of the terminal 2 of the sewing machine to which the machine number is attached.

The operation of the work command system configured as described above is explained first.
This will be explained according to the flowchart shown in FIG.

Now, by operating the input device 7 in advance, the worker's name and skills possessed are stored in the worker data memory section of the external storage device 6, and the machine number and its possessed functions are stored in the machine data memory section. Furthermore, the manufacturing T1 priority order memory section stores manufacturing items such as shirts, the manufacturing priority determined for each item, and data for each item (not including the lot number of the pulled parts). , the processing procedure memory section for each manufacturing item contains information on the workers required to manufacture the manufacturing item, such as a shirt, the processing order to perform the work, the necessary skills and functions of the machine necessary to perform the work. Data representing is stored.

A predetermined manufacturing item (this product/product) is selected by key operation on the input device 7.
In example A, a cutter shirt) is selected □, and a command signal for continuously displaying the machining process table for that manufacturing item is output to the CPU 3 (step 1, hereinafter step is represented by S).
Based on No. 43, P=U3 displays a work process analysis table as shown in FIG. 9 on the display V18 based on the data of the workers and the normal work order to perform the work from the processing procedure memory section for each manufacturing item. The matrix enters water (S2). In this work process analysis table, each work] is determined according to a unique ranking, and follows the ranking represented by numbers a01 to a15.

Next, the operator uses the cursor movement key and machining order range setting -1- (both not shown) to select the work process analysis table displayed on the display device 8.
A predetermined worker whose work order can be changed is selected using the cursor displayed on the display device 8, and the range of the selected work order is expanded to J as shown in FIG. 10 (S3).
. In this example, the rank of "buttonhole stitching" is a
In the range of 03 to aQ4, the rank of "Pocket Ro stitch" is ao
In the range of 1 to a04, the rank of "Kibushi" is a12 to a13
In the range of , the rank of "three sleeves" is in the range of a11 to a13, the rank of "with collar button" is in the range of 814 to a15, and the rank of "patch collar" is in the range of 814 to a15. will be expanded to.

The CPU 3 stores each worker and the set rank range data inputted at this time in a predetermined storage area of the external storage device 6, and when the input of the rank range for this work is completed (84).
, CPIJ3 contains the stored worker and rank range data and! Branching processing (network processing) of the work process analysis table is performed based on the memory map stored in the manufactured item processing procedure memory section (S5).

In S5, for example, "pocket ro stitch" is 1 incense a01~
When each setting is made to a04, the CPU 3 performs the program before and after the task. Determine all possible prohis. Similarly, other tasks for which ranking ranges have been set (such as "buttonhole stitching" and "neckline").

The branching process is also performed for "sode mitamaki," etc.).

Then, the CPU 3 determines whether or not the determined process is normal (86), and if it is determined to be normal, for example, in the case of "Pocket Loop Stitching", the CPU 3 determines whether the determined process is normal or not. The next work name related to ``, ``G with pocket'' is sequentially stored in the next work candidate memory section as shown in Fig. 6 (S7); In this case, the names of the related next work are ``three hem wraps'' and ``collar attachment,'' and the subsequent work names of ``neck flap'' are memorized in sequence, such as ``attaching collar buttons'' and ``sewing collar holes.'' . At this time, the name of the work that is the next work for each work is stored with a read-out priority given to it. That is, in addition to the normal start order, a branch start order is given to work process names that can be branched, such as "side-joining sleeve bottom stitching". By assigning work order data to predetermined tasks in this manner, a work process analysis table as shown in FIG. 13 is created.

Next, the processing performed based on the new work process analysis table created based on IJ based on the ranking range data will be explained with reference to the flowchart shown in FIG.

After starting sewing, the external memory S! Various types of data are stored in the work order data measuring section, machine data memory section, manufacturing priority order memory section, manufacturing item processing procedure memory section, and next work candidate data memory section in position 6, and the work data corresponds to each job. Pre-worked sign, processed re-in,
Various nines of the machining quantity nines are stored according to the work status being performed at that time. Now, when a work instruction request signal is input to the CPU 3 from the terminal device 2 (811
), the CPLI 3 releases the protection so that the next work candidate data memory section can be read based on the work instruction request signal, and then releases the work process currently being worked (processed) stored in the work arc memory section. A search is made based on the processing-in-progress sign, and a rough search is made for the next work process of the searched work process and the work process for which the previous work-completed sign has been completed and there is no processing-in-progress sign or processed sign. Then, those work steps are not read out from the next work candidate data memory section according to their read priority order (812>).

In S13, the CPU 3 determines whether or not there is a work step that can be started from among the next work that has been read out, based on the data stored in the work data memory section.
The next step is read out in step S8, and the same process is performed in step S13. When it is determined in 813 that the next work that can be started is right, in 814 the optimal conditions such as the possessed skills and necessary functions necessary for the next work (for example, the conditions with yarn, skill level, transportation loss, etc. ), and if there is no optimal condition, the process moves to 818 to read out the next work candidate, performs the same processing in 813 and 814, and stores all of the checked next work candidates in a predetermined location in RAM 5. Store in storage area.

Then, in S15, U selects the optimal next work culm based on the checked optimal conditions among the next works stored in the RAM 5, and then selects them so that instructions for the next work process other than the selected optimal next work process are not issued. The next work is protected (S16). Then, the CPLJ3 transmits data such as the selected optimal work instruction, that is, the optimal work name, machine number, lot number, etc. to the terminal device 2 that requested the work instruction request signal.
(817). The terminal device 2 stores the transmitted data in a buffer, and when the end switch is closed, the terminal device 2 displays the data stored in the buffer on the liquid crystal display device based on the end number 18 from the end switch. display,
Give work instructions.

Further, when the end signal is generated, the end signal is transmitted to the CPU 3 via the terminal device 2, and the CPU 3 detects the machine number of the sewing machine to which the terminal device is installed based on the end signal. , delete the in-use sign corresponding to the machine number in the machine data memory section, delete the machining in-progress sign corresponding to the job name in the work data memory section, memorize machining flow 1 nine, and store the job name. The previous work completed sign corresponding to the work name of the next rank is stored.

If the optimal work name selected in this way is a work process that is given a branch starting order such as "1 side-joining sleeve opening" in Figure 13, the next work is selected while this optimal work is being executed. When doing so, the CPU 3 uses the optimal work assigned the selected branch starting order as a reference. On the other hand, in the case of a work process to which a normal starting order is assigned, such as "front stand", when selecting the next work while this optimal work is being executed, CPtJ3 Usually, the optimal work assigned a ranking is used as the standard.

It should be noted that this invention is not limited to the above-described embodiments, and may be modified as desired without departing from the spirit of the invention.

(Effects of the Invention) As detailed above, the present invention is highly flexible in selecting the order of work in the work process, so it is possible to shorten the processing time of products and to make effective use of equipment. Creates a immersive effect.

Furthermore, this system can be used not only for fabricating component parts of clothing such as shirts, but also for sewing shoe covers, gluing shoe soles, etc.
