Description

  The present invention relates to a cell production work management system and a cell that achieves immediate parts supply by speeding up work proficiency of workers and improving work accuracy in cell production, and synchronizing cell work area and parts supply The present invention relates to a production work management method, a cell production work management program, and a recording medium on which the program is recorded.

  Conventionally, a so-called cell production system is known in which one person or a small number of people are in charge of the entire process of one product (see Patent Documents 1, 2, and 3). In this type of cell production system, for example, in the assembly manufacturing industry, usually a plurality of workers share the mounting of predetermined parts, partial assembly of products, processing, inspection, and the like. Usually, work is performed in cells (for example, work tables) arranged in a U-shape or the like.

  In the cell production system, it is possible to easily change production items (product variations, etc.) simply by replacing parts boxes and changing the work order of workers in the cell. The production volume can be adjusted by adjusting the number of people in the cell or by increasing or decreasing the number of cells.

In a normal line production system, if the productivity of any process on the line decreases, that process becomes a bottleneck. For this reason, even if the production capacity of other processes is high, the capacity may be wasted. On the other hand, in a cell production system, even if a certain cell is stopped, other cells are operating independently, and thus the above disadvantages are unlikely to occur.
In the supply of parts to the cell (cell work area), the parts supplier regularly looks around the parts shelves in each cell, and supplies parts to the parts shelves when the number of parts decreases.

  However, in the cell production system, it takes time to become familiar with the work in the cell, and the work efficiency varies depending on the worker in each cell. In addition, for example, there is a problem that parts inventory in the entire production facility becomes excessive or small.

  Further, parts necessary for work in the cell are supplied in advance to the cell parts shelf before starting the work, but the current number of supplies is arranged without management. Therefore, as described above, the component supplier periodically monitors the status of the components remaining on the cell component shelf on a relatively frequent basis, and if the component supplier thinks that the number of the component suppliers has decreased, the component supplier Will provide.

  Therefore, when carrying out regular monitoring, if you do not carry replenishment parts, go back to the parts inventory shelf and go to the cell parts shelf after acquiring the required number of parts and go to the cell parts shelf. It will be supplied and is complicated. On the other hand, if the parts supplier circulates the facility with parts during regular monitoring, the relevant parts that were carried are supplied as soon as a cell parts shelf with fewer parts is found. There is no need to return to the parts inventory shelf. However, there are a large number of parts, and it is unrealistic to go around for monitoring while carrying all the parts.

  In addition, in the conventional parts monitoring and supply method, when it is determined that the number of parts in the cell parts shelf has been reduced, an appropriate number of parts have been supplied. Easy to fall into. In other words, there are a plurality of parts necessary for manufacturing a certain product, but the number of all parts used is not equal, and some parts are used in large numbers, and some parts are used only one or a very small amount. In such a case, of course, in the case of a part that uses only one or a very small amount, the number placed on the cell parts shelf should be small, but parts supply because the physical remaining amount is small. Will replenish the parts. As a result, parts are supplied more than necessary, resulting in an excessive supply state. If an excessive supply state occurs in each cell in this way, the number of parts to be prepared in the inventory parts shelf increases accordingly, resulting in an excessive inventory, resulting in increased production costs. Further, when the parts supply is concentrated on one cell part shelf, there is a possibility that the part is missing in another cell part shelf even though the part exists in the production factory.

  Furthermore, since the parts are supplied to the cell parts shelf regardless of the production process in the cell, a phenomenon that a large number of parts remain often occurs even when the production number of a certain product assigned to a certain cell is completed. This is a kind of oversupply and causes the same problems as described above. Furthermore, in one day's work, a plurality of types of products may be produced in one cell. In such a case, when the production of one cell is completed, a large number of parts are produced as described above. If it remains in the parts shelf, it will interfere with the next product (because of different types, different parts are used). In other words, if parts that are not originally used remain in the cell parts shelf, not only may there be a risk of selecting and using the wrong parts, but also parts that may be used in other cells are not used. It is unpreferable to leave it alone as it has a wasteful inventory.

The date and time of pressing the “Next” or “End” button on the operation panel is registered in “Work End Time”, and the “Work Actual Time for each Detailed Procedure” is (End time-work start time) is registered.

  As shown in FIG. 14, the work performance time analysis unit 145 analyzes the work performance time of the worker with reference to the work procedure DB 2 based on the data registered in the work performance database DB3. The work performance time analysis result output means 146 outputs the analysis result by the work performance time analysis means 145 to the administrator terminal 12 via the network 100. The administrator terminal 12 includes a work time changing unit 121. The work time changing unit 121 refers to the analysis result by the work performance time analysis unit 145 and determines each work time registered in the work procedure database DB2. change. Thereby, feedback can be given to the work standard time of each work according to the work proficiency level of the worker.

  As shown in FIG. 15, the work performance time analysis means 145 analyzes the difference between the work standard time registered in the work procedure database DB2 and the performance time registered in the work performance database DB3, and the analysis result is managed by the administrator. The data is transmitted to the terminal 12 via the network 100 (S501), and the administrator terminal 12 displays the analysis result for each worker A (S502). Based on the analysis result, the administrator B uses the work time changing unit 121 to change the work standard time as described above (S503), transmits the changed work standard time to the management server 14, and the management server 14 Updates the work standard time registered in the work procedure database DB2 instructed to change.

  As shown in FIG. 16, the part registration means 147 registers the type and quantity of parts used in each cell S and the replenishment point quantity to the parts shelf of the cell in the parts database DB4. The parts supply instruction output means 148 calculates the number of parts in stock in each cell based on the data registered in the work performance database DB3 and the cell parts shelf inventory database DB5, and the parts registered in the parts database DB4. When the number is reduced to the replenishment point, a component supply instruction is output to the component supply instruction terminal 13 via the network 100.

  That is, as shown in FIG. 17, the administrator terminal 12 inputs the part configuration information for each type, the supply instruction point quantity to the cell parts shelf, and the supply unit (S601), and this input information is input via the network 100. It transmits to the management server 14. The management server 14 registers the received component information in the component database DB4 (S602). In the parts database DB4, the types and quantities of parts used for product assembly work, etc., and supply instruction point quantities and supply units to the cell parts shelf are registered.

  FIG. 18 shows the registration contents of the component database DB4. In the parts database DB4, “used parts”, “number”, “supply instruction point”, and “supply unit” are registered according to “product number”. “Product number” consists of a product type code, “Used part” contains the part code to be used, “Number of parts” registers the number of parts used, and “Supply instruction point” instructs parts supply The quantity to be a point is registered, and the supply unit quantity at the time of component supply is registered in the “supply unit”.

  As shown in FIG. 19, the component supplier C inputs the supply quantity at the time of supplying the component to the cell component shelf at the component supply instruction terminal 13 (S701), and transmits this to the management server 14. The management server 14 registers the received number of supplied parts in the cell parts shelf inventory database DB5 (S702). The cell parts shelf inventory database DB5 is composed of cell parts shelf inventory information for managing the inventory quantities of the parts shelves of each cell, and the inventory quantity is added when the parts supplier supplies the parts.

  In addition, the worker terminal 11 presses an “end” button on the operation panel to notify the management server 14 of completion of one or one assembly work (S703). Upon receiving this notification, the management server 14 acquires the number of parts used for one or one assembly from the parts database DB4, and subtracts the number of parts for one unit from the cell parts shelf inventory database DB5 (S704). . That is, the inventory quantity is subtracted when the worker A completes one or one work.

  FIG. 20 shows the registration contents of the cell parts shelf inventory database DB5. In the cell parts shelf inventory database DB5, “cell code”, “part number”, “used parts”, and “stock quantity” are registered, and “cell code” contains the code attached to the cell. The product type code is registered in the “product number”, the part code to be used is registered in the “used part”, and the stock quantity of the part is registered in the “stock quantity”.

  FIG. 21 shows the exchange of parts information between the worker terminal 11 and the management server 14 and the exchange of parts supply instruction information between the parts supply instruction terminal 13 and the management server 14. When the worker A completes the work with one or one unit and presses the “end” button on the operation panel by the worker terminal 11 (see S115 in FIG. 7 or S214 in FIG. 8), “end” Is notified to the administrator server 14 via the network 100 (S801). The administrator server 14 acquires the number of parts used for one or one assembly from the parts database DB4, and subtracts the number of parts for one from the cell parts shelf inventory database DB5 (S802).

After the inventory update, the administrator server 14 transmits the component supply instruction to the component supply instruction terminal 13 via the network 100 when the number of parts inventory reaches the supply instruction point managed by the component database DB4 (S803). .
Supply number is
(Number of work plans-number of work results) ≥ If supply unit, it is the unit registered in the parts database,
If the number of work plans minus the number of work results is less than the supply unit, the remaining number of plans is assumed.

  When the component supply instruction terminal 13 receives the component supply instruction, the component supply instruction terminal 13 displays the component supply instruction to the cell (S804). Then, the component supplier C inputs supply quantity information from the operation panel of the component supply instruction terminal 13 when supplying the component to the cell (S805). When receiving the supply amount information, the management server 14 registers the supply amount in the cell parts shelf inventory database DB5 (S806).

  In this way, supply to the cell parts shelf is more than necessary to supply the cell parts shelf in order to supply the necessary and sufficient (no excess or deficient) quantity of parts necessary for the product to be produced in consideration of the work performed in the cell. This eliminates the need for parts to be missing in other cell work areas due to the supply of parts and the need to have a large inventory. In addition, since the cell work area and the parts supply are synchronized, the parts supplier does not need to go around the area and monitor the presence of parts to be replenished, and waits for an instruction from the parts supply instruction output means. Since it suffices to supply a desired cell component shelf to the designated cell component shelf, it is efficient.

  Furthermore, since the required number of parts used for the product produced in the cell work area is supplied, the number of parts required for manufacturing the product is small and placed on the cell parts shelf. Even if the remaining number of such parts is small, it is not necessary to supply in a hurry, and it is possible to prevent an oversupply state. Furthermore, since the number of products produced on that day is managed in the cell work area, it is sufficient to supply only the necessary quantity of the necessary parts. It can be managed so that no parts remain. As a result, if there are parts remaining on the cell parts shelf at the end of the work, it is immediately known that a production error has occurred, so that the subsequent confirmation work can be easily performed, and even if the disposal process is performed, a small amount is required. That's it. In other words, when all the parts are eliminated at the end of the work, the probability that all the parts have been used without fail increases. In addition, if the necessary parts for the products to be produced that day are supplied to the cell parts shelf in the required quantity, the number of stocks in the entire production plant can be reduced as much as possible, thereby reducing costs. be able to.

  Of course, the number of parts to be supplied to each cell parts shelf at the start of work does not need to supply all the parts used for the product to be produced on that day. It will be replenished.
