Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a 9R management device for an automated parts supply warehouse used, for example, in an automation system for a processing and assembly line.

(Prior Art) In recent years, automation of processing and assembly lines has been progressing in the direction of enabling flexible response to high-volume, low-volume production. In other words, it is not only possible to introduce VJ equipment to simply save labor and labor, but also to be able to accurately grasp the progress and status of manufacturing, immediately respond to instructions for changes in manufacturing, and improve processing and assembly. is changing'! This refers to automation aimed at increasing the sophistication of information processing.

In order to achieve this flexibility, robots, automatic guided vehicles, and automatic QFK have been introduced to processing and assembly lines, and they have come to perform various functions by organically combining them with information processing systems and communication lines.

On the other hand, due to changes in the market structure and increased sophistication of production management, processing and assembly lines are required to shorten delivery times, that is, shorten production times and reduce inventory. In order to meet this demand, it is necessary to shorten not only the assembly time and processing time itself, but also the time required for logistics.In addition, it is necessary to reduce the supply of parts to the processing and assembly line to the minimum necessary, and to reduce the amount of work in progress on the line. This results in a reduction in parts and material inventory.

In order to shorten the manufacturing time and reduce the amount of parts and materials used, it is necessary to improve the reliability of the manufacturing equipment, and in particular, it is important to improve the reliability of the logistics and storage system. Otherwise, if the automatic C warehouse or conveyor breaks down, the supply of parts and materials will stop, reducing the amount of parts and materials on hand on the line, and production will be halted in a short period of time. It is.

Conventionally, production stoppages have been avoided by keeping sufficient parts and material inventory on the production line, or by providing an emergency transportation and storage system in addition to the original transportation and storage system.

(Problem to be solved by the invention) However, if the production line has sufficient inventory of parts and materials, or if an emergency transportation and storage system is installed, the increase in the amount of in-process inventory can be avoided. There was also the problem that equipment costs increased.

This invention has been made in view of these conventional problems, and it provides an automatic warehouse system for supplying parts in assembly processing lines without increasing equipment costs or increasing in-process inventory. , which can be made highly reliable
The purpose is to provide a link management device.

[Measurement Constituent (Means for Solving the Problem)] The warehouse management device of the present invention includes a warehousing device, a warehousing device,
A warehouse controller that stores incoming parts into a storage shelf at a specified address and outputs the stocked parts from the storage shelf at a specified address, an input unit that inputs the quality of the parts to be warehoused, and a warehouse controller that stores multiple warehouses. an address determination unit that sequentially determines storage shelf addresses for each component type in each management zone, an Otsu command unit that outputs a warehousing command to the warehouse controller, and a warehousing completion processing unit that performs warehousing completion processing. , a warehousing determination unit that receives a warehousing Un request and determines the parts to be warehousing, a warehousing command unit that outputs the warehousing of the determined parts to the warehouse controller, a warehousing completion processing unit that performs a warehousing completion process, and a warehousing completion processing unit that performs a warehousing completion process; It is equipped with a zone management section that sets whether entry/exit is allowed or not.

(Function) In the warehouse management device of the present invention, the warehouse is administratively divided into a plurality of zones that can be operated independently, and the zones for storing parts to be stored under pressure by type are distributed and allocated. Even if a part of the warehouse zone that can be operated becomes inoperable due to a malfunction or other reason, parts and materials can be stored in other zones, and parts can be taken out from other zones. , it is possible to manage the warehouse without stopping production.

(Example) The present invention will be described in detail below with reference to the drawings.

FIG. 2 shows a parts supply warehouse system for delivering parts to a production line to which an embodiment of the present invention is applied. The 8-warehouse parts supply system shown in Fig. 2 includes a warehouse management device 1, a warehouse controller 2 that controls warehouse equipment, a warehousing device 3 that transports incoming parts, and a rotary rack 4 that stores parts.
, and an unloading device 5 that takes out parts from a rack 4 and transfers them to a transport device of a production line.

FIG. 1 is a block diagram of a warehouse management device 1 according to an embodiment of the present invention, which includes a CRT terminal equipment 6 that specifies the type of parts to be stocked and makes a stocking request, and an input section 7 that processes this input.
and an address determining unit 8 that determines the shelf address of the empty shelf.
It is equipped with a receiving command unit 9 that outputs a receiving command to the warehouse controller 2, and a receiving completion processing unit 12 that receives a notification of receiving completion from the Ω warehouse controller 2 and updates an inventory file 10 and an empty shelf file 11. .

Further, there is a CRT terminal device 13 that specifies the shipping type and makes a shipping request, a zone management unit 14, a shipping address determination unit 15 that determines the shipping town address, and an 0R controller 2.
A shipping command unit 16 outputs a shipping command to the inventory file 10 upon receiving notification of shipping completion from the warehouse controller 2.
and a Tsuchiura completion processing unit 17 that updates the empty shelf file 11.

Furthermore, it includes a zone management data file 18 and one part-specific management data file.

As shown in FIG. 3, the zone management data file 18 includes a total number of zones 20, a zone number 21, and a zone shelf address 2.
2. It has a structure consisting of a warehousing prohibited flag 23 and a warehousing prohibited flag 24 for each zone.

The component-specific management data file 19 has a structure in which +, 2, . . . and the final warehousing zone number 25 are compared for each component type, as shown in FIG.

The operation of the warehouse management device having the above configuration will be explained next. Referring to the flowchart shown in FIG. 5, if you now try to input parts into the parts type from the warehousing device 3,
The operator sets the parts on the incoming Hffi3 and displays the CRT.
The product type K is input from 6 and a warehousing request is made to the input section 7.

In step $, the address determining unit 8 retrieves the final warehousing zone number n for the product type from the parts management data file 19.
1), by adding “1”, the current warehousing zone number M(
n+1> is obtained (step 82).

Next, search the zone management data file 18 to determine whether the designated warehousing zone is a warehousing shelf or not.
3 to $5), if it is a storage shelf, search the empty shelf data file 11 for the empty shelf in the zone (step S6), and if there is an empty shelf, update the empty shelf data file 11 and set the storage determination shelf address A ( K) and outputs it to the warehousing command unit 9 (steps S7 and S8).

If the specified zone cannot be stocked or there are no empty shelves,
Moving to the next zone, empty shelves are searched for in the empty shelf file 11 (steps 89 and 810). If no empty shelf is found, storage is prohibited (step 511).

Once the receiving shelf address is determined in this way, next
The warehousing command unit 9 gives a command to the warehouse controller 2 to stock the designated warehousing shelf address A(K).

The warehouse controller 2 drives the equipment and stores the corresponding parts in the designated aA(K).

When storage is completed, the warehouse controller 2 notifies the warehousing completion processing section 17 of a warehousing completion notification. Warehousing completion processing unit 12
writes in the inventory file 10 that parts of the quantity IK are stored on the shelf A(K).

At the same time, empty shelf address △(K) of empty shelf file 11
Moisturize.

By inputting parts under pressure in this manner, parts of the same type are evenly distributed and stored in the n management zones of the Q warehouse.

Next, the case where parts of a particular type are shipped will be explained with reference to the flowchart shown in FIG.

Requests from other systems such as production management systems, or C
A delivery request is input to the delivery determination unit 15 based on the delivery setting from the RT terminal. The shipping determining unit 15 searches the inventory information file 10 and obtains the parts storage shelf address A(K) for the product type that was stocked first (step 521).

Next, the zone management data file 18 is checked to determine whether the obtained storage shelf address A (K) is in the retrieval zone (step 522).

If it is in the soil pressure impossible zone, store shelf 5 of the next candidate for the variety.
Search for address A(K) and determine the zone where delivery is possible (step 823.21.22) This step S22
When you find the stored parts in the retrieval zone,
The storage address A(K) is output to the shipping command unit 16 (step 524).

The delivery command unit 16 outputs the input delivery command to the 0B controller 2 and causes the corresponding part to be delivered.

In addition, when a part of the warehouse equipment becomes unusable due to a malfunction or the like, the operator commands the zone that has become unusable due to the malfunctioning part from the CRT terminal device 13 to indicate a state in which no entry or exit is possible. set.

The zone management unit 14 inputs instructions such as "Arriving not allowed", "Leaving is not allowed", "Entering is possible", and "Leaving is allowed", and sets and resets the "Arriving not allowed" flag 23 and "Lefting not allowed" flag 24 of the zone management data file 18 shown in FIG. and update the zone management state.

As explained above, the same parts are evenly distributed and stored in each of the multiple management zones in the warehouse, and even if some zones become unusable, they can be stored in the remaining management zones. On the other hand, it is possible to carry out warehousing and unloading operations, and it is possible to continue supplying parts and materials to the manufacturing line.

In the above embodiment, in order to allocate a zone that can be operated independently as a management zone, each storage shelf of a multi-stage rotary rack that rotates independently and can be loaded and unloaded is set to one storage shelf.
They were grouped together into one zone.

In addition to the above-mentioned embodiments, the input*shelf determination algorithm of the warehousing address determination unit 8 also maintains the storage number in the management zone for each component type, and when determining the zone, stores the number of storage units in the management zone. It is also possible to select an empty shelf in a zone where the number of corresponding parts stored is the least among the zones with empty shelves, and this is particularly limited as long as the algorithm can store the parts evenly distributed within the management zone. There isn't.

In general, although the above embodiment describes an automated warehouse system using the rotary rack 4, other types of warehouse systems can also be used, for example,
Even in an automated warehouse system with multiple stacker cranes, the same effect can be achieved by allocating the shelves covered by each stacker crane as a management zone.

[Effects of the Invention] As described above, according to the present invention, the home is divided into several management zones, and each part is evenly distributed and stocked in each management zone by type, so that a certain Even if it becomes impossible to stock/output parts from a management zone, it is possible to continue managing parts inventory by stocking/unloading parts from the remaining normal management zones, thereby reducing work-in-progress due to an increase in the number of inventories in the warehouse. It is possible to continue the supply of parts even if a part of the warehouse equipment breaks down without causing an increase in m, and without installing new extra equipment, and it is possible to improve the equal reliability of parts storage and supply.
