Description

The present invention relates to a parts management system, and more particularly to a parts management system directly connected to a production line.

[Prior art]

Electronic components used for printed wiring boards and the like are temporarily stored in a predetermined shelf of a warehouse, and the required number of electronic components are output from the warehouse on a production line.

Some of the parts stored in the warehouse are purchased goods and those transferred from other warehouses (which have already been purchased and received, and are called warehouse transfer goods). The storing procedure was as shown in FIG.

That is, first, at the same time as unpacking, check the model (code to identify the part) and quantity of the part, check the model of the part in the outer box of the part, and the storage bin number when storing the part in the warehouse. Fill in (F11 → F12). Further, a receipt stamp (date) is stamped on the outer box, and then the parts are sorted by shelf number to store them, and the sorted parts are temporarily stored in a warehouse. (F13 → F
14). Furthermore, after that, the parts that were not in the required number on the production line (hereinafter referred to as "out of stock") are taken out from the warehouse and replenished (F15). All these tasks were done manually.

[Problems to be Solved by the Invention]

Since all the work is manual work as described above, it takes a lot of man-hours and time, and there is a possibility that an error may occur when the model name is transferred.

In addition, when assembling various parts such as a printed wiring board, among the parts required on the production line,
In some types, the required number of parts, that is, a shortage, occurs, and in this case, basically, it is impossible to proceed with the intended manufacturing process of the printed wiring board. If the arrival date of a certain part is known, it is possible to decide the start time of the mounting work that requires that part.However, according to the above conventional method, the manufacturing line side does not know the arrival status of the part There is a difficulty in deciding when to start. Further, even if the work is preceded, if the arrival of the part is delayed, the line is stopped and waited, or the process is advanced with only the part. The method of stopping the line causes a large time loss, and when the parts are mounted on the printed wiring board in the state that the missing parts are removed, the replenished parts are mounted by hand soldering when the missing parts are replenished. It is necessary, takes a lot of time, and there is a possibility that the defective rate increases.

Furthermore, even if the production starts after the missing parts are received, all the received parts are temporarily stored in the warehouse (automatic warehouse, etc.).
Since the necessary quantity is carried out to the manufacturing line after that, there is a drawback that the manufacturing line waiting for the arrival of the missing item cannot be replenished early.

Furthermore, according to the above-mentioned conventional method, since the model, storage, shelf number, etc. of the received parts in the outer box are all filled in manually, there is a possibility that erroneous writing may occur.

This invention has been proposed in view of the above-mentioned conventional circumstances, and even in the production line, it is possible to determine the operating time of the line by grasping the out-of-stock situation in the warehouse and the expected arrival date, the arrival quantity, and It is an object of the present invention to provide a parts management system capable of supplying parts to a production line immediately when a requested part arrives on the production line without going through a warehouse.

[Means for solving the problem]

In order to achieve the above object, the invention employs the following means. That is, at the time of receiving the parts, a code for identifying the parts related to the purchased parts or the transfer parts and the number of the received goods are registered as reception data, and further,
On the other hand, when the parts are shipped from the warehouse to the production line, the shortage quantity with respect to the required quantity on the production line is registered as the out-of-stock information.

After that, the stocking data corresponding to the stocking quantity obtained by subtracting the shortage of parts on the manufacturing line indicated by the shortage information from the stock quantity is created, and the replenishment processing for the shortage of parts on the manufacturing line is performed in the warehouse Try to do it without going through.

When the planned arrival date of the missing item is known, the planned arrival date is also registered as the missing item information, and the production line starts operation in accordance with the expected arrival date.

〔Example〕

 FIG. 1 is a conceptual diagram showing an embodiment of the present invention.

A plurality of input personal computers (hereinafter referred to as personal computers) 2 are connected to the host computer 1.

To the host computer 1, the shelf number data 12 created by the production management system 3, that is, the data relating to the shelves in the warehouse and the delivery check data 11, that is, how many parts of what type are brought out from each shelf in the warehouse. When the stock quantity is insufficient or the stock quantity is insufficient with respect to the required quantity, data such as the shortage quantity (missing stock information 11a) is registered. These data are transferred to each personal computer 2 online or by floppy, and the same data 11 (11a) and 12 are registered in each personal computer 2.
When new parts are received in this state, first,
As the acceptance data 13, the product type (a code for identifying the part) and the number of arrivals are input to the personal computer 2 and are transmitted to the host computer 1 as the acceptance data 13.

After the above-mentioned input processing, the host computer 1 performs the out-of-stock processing for parts that are out of stock. That is,
If there are currently 50 parts on line A, 10 on line B, and 15 on line C, and there are 100 in stock, 50 parts on line A, 10 parts on line B, and 15 parts on line C Input to replenish. As a result, 25 parts will be stored in the warehouse. The data after the out-of-stock process is carried out in this way becomes the stocking data 14, that is, the current inventory quantity, and is used as a reference when determining the number of parts to be purchased afterwards in the upper production management system 3. Further, when the number of replenishment of missing items is edited, the missing item replenishment data 15 is supplied to the production line control system 4.

When the data processing at the time of warehousing is completed, the parts are directly carried into the manufacturing line based on the lacking-item supplement data 15. On the other hand, in the higher-level production management system 3, when the estimated arrival date of the missing item is known, the estimated arrival date is entered, and the delivery check information 11 (or the missing item information 11a) is entered by the production management system 3 described above. The expected arrival date of the missing item is registered. As a result, on the line side, the line has been operated to the extent that it would not be necessary even if the parts were missing before the missing items were replenished, or the line operation schedule was set according to the arrival schedule. . With this, the production line can immediately operate the line according to the number of replenishments.

Further, according to the input data at the time of reception, that is, the reception data 13, a bar code to be attached to the outer box in which the part is stored is issued from the bar code printer. Information such as the date of processing, the model number of the part, the shelf number, etc. is included in this bar code, which relieves the conventional turning work of the above matters and eliminates the erroneous writing associated therewith.

〔The invention's effect〕

As described above, according to the present invention, it is possible to grasp the situation of out-of-stock items in each manufacturing line at the time of receiving the parts, and to immediately replenish the manufacturing line without temporarily storing the parts. Can be reduced. Further, since the line is operated according to the scheduled arrival date of the missing item, there is an advantage that the work efficiency can be improved.
