Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for controlling delivery of parts from a plurality of parts warehouses. As the functions of electronic devices and communication devices have become more sophisticated and complex, the number of products has increased,
Its production has been reduced to smaller lots and shorter delivery times.

[0002] In the manufacturing factory, the delivery of parts from the parts warehouse that stores the parts is the first step of the manufacturing process, and the efficient delivery of parts greatly contributes to shortening the production turn. .

In a large-scale manufacturing factory, the parts warehouse becomes large, and the parts used for one device may be distributed and stored in a plurality of parts warehouses. There is a demand for a method of controlling delivery of parts from a parts warehouse that can efficiently deliver parts from a plurality of parts warehouses in synchronization with each other.

[0004]

2. Description of the Related Art FIG. 6 is a diagram for explaining a conventional example. In the figure, W1 to Wn are parts warehouses, 10 is a processing device for controlling the delivery of parts, F1 is a delivery command file, F2 and F2 'are inventory files, F2A and F2A' are shelf files, and F1A is a delivery command capable file. , F1b are stagnation file incapable of issuing instructions.

The delivery of parts from the parts warehouse in the manufacturing process is controlled by a computer system, and the processing device 10 performs the issuing command processing while collating and updating the contents of each file.

A shipping command for parts is written in the shipping command file F1. The processing device 10 calculates "inventory number-delivery instruction number" for each part of each production instruction number (hereinafter referred to as production number) from the issue instruction number of the issue instruction file F1 and the inventory number of the inventory file F2. Whether or not the product can be delivered is determined for each product number, and when all the components of the device or the printed board package can be shipped, the product number, the part name, and the quantity of the product that can be delivered are written in the issue command issue enable file F1A.
Inventory file F in which the quantity of the contents of the inventory file F2 and the shelf file F2A is updated with the number of parts reduced by shipping
2 ', shelf file F2A'.

If the delivery is not possible, the serial number, the part name, and the quantity are written in the delivery instruction outbound stagnation file F1b. In each of the parts warehouses W1 to Wn, parts are put out in accordance with the contents of the issuing instruction can be put out file 1A.

[0008]

In the above-mentioned conventional example, when there are a plurality of parts warehouses and the parts warehouses are distant from each other, or when the automatic warehouse and the fixed shelf are used together. The following problems occur when the parts are delivered.

The amount of storage per day from the parts warehouse is determined by the capacity of the manufacturing process. However, the number of delivered items varies among a plurality of parts warehouses.・ It becomes difficult to synchronize work due to unbalanced load between parts warehouses.

An extreme delay may occur depending on the parts warehouse. -In particular, when the delivery capacity is determined by the mechanical capacity, such as in an automated warehouse, the overload will delay the delivery of parts.

In order to solve such a problem, it is possible to increase the number of workers and increase the delivery capacity in the case of a warehouse using fixed shelves by calculating the number of warehouses per unit warehouse per day. , It is not possible to easily increase the shipping capacity in automated warehouses.

According to the present invention, when a part is delivered from a plurality of parts warehouses, the parts warehouse with the largest load is extracted, the product numbers having common storage addresses in the parts warehouse are rounded, and the rounded result is used again. If the load is calculated and the load is less than or equal to the holding capacity of the parts warehouse, the parts are delivered according to the rounded result. If there is a warehouse where the load exceeds the holding capacity of the parts warehouse, the load is exceeded again. The present invention aims to realize a parts delivery control method from a parts warehouse that can synchronize parts delivery among the parts warehouses by performing rounding processing of the parts warehouses.

[0013]

FIG. 1 is a diagram for explaining the principle of the present invention. The figure shows a method of controlling the delivery of parts from a plurality of parts warehouses W1 to Wn. In STEP 1, the stock number of the parts instructed to be issued in the delivery command file F1 is checked from the inventory file F2. The production numbers including the missing parts are excluded from the shipping target, and in STEP 2, the number of shipping commands with no missing parts is set to a plurality of parts warehouses W1 to Wn.
The number of items issued is classified separately, and in STEP 3, the sum of the number of unissued items for each parts warehouse W1 to Wn and the number of items issued for each parts warehouse W1 to Wn in the in-process number file F3 is calculated. .

Then, in STEP 4, the sum of the number of deliveries is compared with the holding capacity of each of the parts warehouses W1 to Wn in the capacity holding table T1 to identify the parts warehouse Wi having the largest excess load with respect to the holding capacity. In STEP 5, the parts warehouse Wi
Outgoing commands having a high degree of commonality of shelf addresses for storing outgoing parts are collectively set as a shipping unit.

[0015]

A plurality of issuing commands for the plurality of parts warehouses W1 to Wn are written in the issuing command file F1.
The parts inventory of each parts warehouse W1-Wn at that time is written in the inventory file F2.

Here, it is judged whether or not the quantity of parts indicated in the goods issue command file F1 can be taken out, by comparing with the quantity of parts in the inventory file F2, and if there are missing parts, the missing parts The production numbers including parts are excluded from the delivery target, and the production numbers that can be delivered are determined.

The sum of the production number determined here and the number of work in progress for each of the parts warehouses W1 to Wn in the number of work in progress file F3 for each warehouse, and the number of deliveries are calculated, The value of the number of delivered goods is compared with the holding capacity for the parts delivery written in the holding capacity table T1 for each of the parts warehouses W1 to Wn. If the holding capacity is large,
Parts can be delivered as they are, so the parts warehouses W1-Wn
Get out more.

If the number of parts delivered exceeds the holding capacity of the parts warehouses W1 to Wn, the delivery of parts will not be completed within a predetermined time, for example, one day which is a work unit. Load reduction processing of the component warehouse Wi of load is performed.

For this reason, the parts warehouse Wi
The storage addresses of the parts are extracted, and the storage addresses for storing the output parts are grouped together by a shipping command having a high degree of commonality to be rounded as one shipping unit.

Based on the rounded-out shipping unit, the number of shippings is again compared with the holding capacity. When the holding capacity is large, the parts are delivered from each of the parts warehouses W1 to Wn in synchronization.

Further, when there is a parts warehouse Wj whose number of deliveries exceeds the holding capacity, rounding processing is performed by the same method, and 1
By unloading as one unloading unit, each of the component warehouses W1 to Wn can be balanced to perform the component unloading process.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 2 is a diagram for explaining the construction of a parts warehouse and the issuing command of an embodiment of the present invention. (A) is an example of the configuration of a warehouse, and here, an automated warehouse WA1 and fixed shelves WF2, W
It consists of F3. The automatic warehouse WA1 has a robot RB for picking up the stored parts, takes out the parts specified by the product number specified by the delivery command, and the fixed shelves WF2, WF3 produce the products specified by the worker. Take out the parts specified by the number and carry out the warehousing.

(B) is an example of a delivery command, and in the order of product numbers,
The model of the part to be used, the parts warehouse in which the part is stored, the number of deliveries, and the shelf address are written. Since the shelf address is not fixed at the free location, the shelf address is specified by the latest data at the time of shipping.

3 and 4 are diagrams (1) and (2) for explaining the process of the embodiment of the present invention. In the figure, F1 is an issue instruction file, F1A is an issue instruction issue possible file, F1a is an issue instruction file by warehouse, F1B is an issue instruction issue impossible file, F11 is an issue instruction number file by warehouse, F2,
F2 'is an inventory file, F2A and F2A' are shelf files, F3 is a number of in-process files by warehouse, and T1 is a holding capacity table.

The process for warehousing parts based on these files will be described below. The structures of the inventory file F2 and the shelf file F2A are as follows.・ Inventory file F2; Part type ── Warehouse number ── Total number of inventory ── Temporary allocation number ・ Shelf file F2A; Part type ── Receipt date ── Stock number ── Temporary allocation number Here, explained in FIG. The stock file F2 corresponding to the part type specified by the serial number of the shipping command in the shipping command file F1 in the format of the shipping command is read.

A1 total inventory number-temporary allocation number ≧ command number,
The command number is added to the provisional allocation number and the shelf file F2A is read. B1 Inventory number-temporary allocation number ≧ instruction number When the command number is added to the provisional allocation number, the shelf address is transferred to the delivery command file F1.

B2 When the number of stocks-the number of provisional allocations <the number of commands, the next record is read and repeated until the number of stocks-the number of temporary allocations> the number of commands. A2 When the total inventory number-the provisional allocation number <the number of commands, the production number cannot be issued, and therefore the production number is written in the issue instruction delivery impossible file F1B.

When the production number of the delivery command is changed and all the parts designated by the production number can be allocated, the provisional allocation numbers of the inventory file F2 and the shelf file F2A are updated to the inventory file F2 '. , A shelf file F2A ', and the serial number is written to the file F1A for issuing a shipping instruction, and the next serial number is processed.

Based on the content of the issue command issue possible file F1A, the issue command numbers are sorted by the warehouse, and the issue command numbers for each automatic warehouse WA1, fixed shelves WF2, WF3 are obtained and written in the issue command number file F11 for each warehouse.

[0030] At that time, the sum of the number of in-process instructions for each warehouse in the file F3 for number of in-process cases for each warehouse is calculated, and the sum of the number of issue commands for each warehouse in the file F11 for the warehouse is calculated and compared with the holding capacity of the holding capacity table T1. To do.

When the sum of the number of in-process cases and the number of shipping command for each warehouse does not exceed the holding capacity of each warehouse, the parts are shipped according to the contents of the number of shipping command for each warehouse file F11.

If the sum of the number of in-process cases and the number of issue orders for each warehouse exceeds the holding capacity, the warehouse having the largest excess load, for example, the automatic warehouse WA1 is recognized. Outgoing command Automatic warehouse W in file F1A
Extract the issue command of A1.

A combination of manufacturing numbers having a common shelf address between the manufacturing numbers in the extracted delivery command is created. When the comparison is made again with the holding capacity of the product number obtained in step 1 in the rounding unit, and when it becomes less than the holding capacity, the rounding unit of the product number obtained in step 2 is set as the delivery unit. Further, even when the rounding process is performed, the rounding product number is increased again and the process is performed again when the holding capacity is exceeded.

Alternatively, as a special case, it is also possible to independently issue the delivery of only this warehouse by processing the issue instruction of the warehouse whose holding capacity is exceeded. FIG. 5 is a diagram for explaining a method of extracting manufacturing numbers having a high degree of commonality according to the embodiment of this invention.

Here, it is assumed that the automatic warehouse WA1 is determined as the warehouse with the largest load, and the serial numbers for unloading the parts from the automatic warehouse WA1 are serial numbers A, B, C, and D. Also,
The automated warehouse WA1 includes shelves 1 to 8.

As a method of extracting product numbers having a high degree of commonality, an address map that represents the product numbers and shelf numbers in a map is used. That is, the shelf number in which the part to be used is housed for each serial number is marked with a circle, and the serial number using the common shelf is extracted.

Here, the serial numbers A and B use the shelves 4, 6 and 8 in common, and the serial numbers C and D use the shelves 1 and 5 respectively.
"Production number A and production number B" because they are used in common,
"Production number C and production number D" are determined to have a high degree of commonality and are rounded as one delivery unit.

By rounding the manufacturing number in this way,
In the automatic warehouse, it is possible to reduce the number of bicks when unloading parts, and in the case of a fixed shelf, it is possible to reduce the number of times a worker moves, and it is possible to improve the parts unloading capacity of each warehouse. .

[0039]

According to the present invention, the load is reduced by paying attention to the warehouse having the maximum load for each warehouse, rounding the product numbers having common storage addresses, and unloading the parts in rounding units. Therefore, it is possible to synchronize the parts delivery work among a plurality of warehouses, and it is possible to easily arrange the surfaces of the parts in the manufacturing process.

Further, it is possible to calculate the true load of the warehouse by carrying out the load for each warehouse again based on the rounded result. Further, since the load for each warehouse can be calculated with a true value, it is possible to appropriately organize and arrange the personnel in consideration of the load for each warehouse.
