Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for issuing an automated warehouse that handles materials or parts of a relatively small variety, and particularly CI
M relates to a method for continuously delivering materials or parts to an integrated automatic production line that operates unmanned day and night.

2. Description of the Related Art In order to improve the operation efficiency of an automated warehouse that handles a wide variety of items, a mixed pallet is stored in response to a request for delivery from a plurality of shelves storing pallets carrying loads. A group of certain first shelves and a second shelf in which a single pallet is stored are divided into groups, the pallets of the shelves of one group are successively output, and then the pallets of the shelves of the other group. There are those in which the products are continuously delivered (for example, Japanese Patent Laid-Open No. 1-162607).

[0003]

However, in the conventional technique, the group is divided into a single-load pallet and a mixed-load pallet,
Since each pallet group is continuously delivered, it is necessary to alternately discharge the materials placed on the single-load pallet and the mixed-load pallet. For an integrated automatic production line that processes and assembles composite parts Has a problem that it cannot be synchronized with the production schedule. Further, when applied to an integrated automatic production line that operates unmanned day and night, there is a risk that a line stop will occur if stock runs out during processing. It should be noted that the conventional technology "single loading pallet" is replaced with "materials or parts with the same part number" to replace the "mixed loading pallet"
It is easily conceivable to replace "with materials or parts with different product numbers". However, if you issue from a group of shelves in which "materials or parts with different product numbers" are stored, you cannot specify the material or parts with the product number that is requested to be issued, and store "materials or parts with the same product number". In the case of paying out from a certain shelf group, it is not possible to meet alternate paying-out requests for a plurality of product numbers, and the same problem occurs. Therefore, an object of the present invention is to provide a method for issuing an automatic warehouse that can be synchronized with the production schedule of an integrated automatic production line that operates unmanned day and night without causing a line stop.

[0004]

In order to solve the above problems, the present invention is directed to an automatic warehouse in which shelves storing materials or parts are divided into a plurality of groups to issue goods in response to a goods issue request from a central CPU. In the shipping method of, when a material or a part is delivered, a group number is assigned to each of the plurality of shelves for storing the same product number as one group.
When a delivery command for the day is received from the central CPU,
In synchronization with the processing schedule, when the shelves of the same group number become empty by the required quantity on the day, the shelves to be sequentially delivered are switched to deliver the materials or parts. Also, when an empty shelf is created in the shelf storing the same product number, the group is reorganized.

[0005]

By the above means, in response to the delivery command for the current day, the materials or parts according to the processing schedule are sequentially delivered to the processing machine or the transport device of the line in the required amount on the day.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the configuration of a file showing an embodiment of the present invention, FIG. 2 is an explanatory view showing shelf numbers and group numbers, and FIG. 3 is a flow chart showing an embodiment of the present invention. The central CPU 1 that manages production has a processing schedule file 2 and a material shelf inventory management file 3. The central CPU 1 is a CIM-compatible model that orders materials or parts based on a production plan, and controls necessary for automatic production such as production command and inventory management. The processing schedule file 2 is a file that has data necessary for controlling the processing machine and conveyance of the line. The material shelf inventory management file 3 has a shelf group management file 31. The shelf group is a shelf that stores the same product number, for example, 1
A group number is defined such that the number two shelves, the number two shelves, and the number five shelves are group 1, and the number three shelves and the number four shelves are defined as group 2, and are registered in the shelf group management file 31. Based on the production plan, when the ordered material or parts are delivered in a quantity that does not cause inventory shortage, the product number and quantity and the shelf to be stored are registered in the material shelf inventory management file 3. At this time, if there is an inventory of the same product number, it is stored in the empty shelves of the same group. If there is no stock with the same part number, define a new group number on the empty shelf and store it. Central CPU in response to the production order of the day
In synchronism with the setup of the processing schedule file 2, 1 issues a command to a processing machine or a conveying device forming a line to pay out a material or a component of a product number required at that stage. Corresponding to the command for this payout, the stock of the shelf group (for example, group 1) in which the product numbers registered in the material shelf inventory management file 3 are stored is checked,
The delivery of the material is instructed to the shelf number (for example, the first shelf) of the corresponding shelf group. For the shelves that have been instructed to issue the material, the material is delivered and the inventory quantity of the shelf group registered in the material shelf inventory management file 3 is reduced by the delivered quantity. When the processing progresses and the stock number of the shelf (first shelf) from which the material is first dispensed becomes 0, another shelf (for example, second shelf) in the same group is instructed to dispense, and the above-mentioned dispensing is processed. Do until done. When the processing is completed, an empty shelf number of the same group number remains in the material shelf inventory management file 3. Now regroup the groups.

[0007]

As described above, according to the present invention, in response to the issue command for the day, the material or the part of the line processing machine or the carrier has a margin for the number of the day processing. Then, the products are sequentially paid out in synchronization with the processing schedule, so that the production can be continued continuously.

Claims (2)

[Claims] Claims: 1. An automatic warehouse issue in which a plurality of shelves with shelf numbers storing materials or parts are assigned to a plurality of shelves in response to an issue instruction from a central CPU. In the method, when a material or a part is delivered, a group number having a plurality of shelves storing the same product number as one group is given in advance to the plurality of groups, and a delivery command for the day is received from the central CPU. , In sync with the machining schedule,
