Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is particularly applicable to efficient stocking when advance control is performed using the manufacturing date of a product as a key in a double reach automated warehouse. The present invention relates to an entry/exit control device suitable for.

[Conventional technology]

Japanese Patent Publication No. 55-39481 was an invention aimed at improving the shipping efficiency of single-reach type automated warehouses, and did not consider double-reach type automated warehouses.

[Problem that the invention seeks to solve]

In the above-mentioned prior art, an invention has been made for improving stocking efficiency with respect to a person-output TX control device in a single-arm automatic warehouse, but no invention has been made regarding a stocking-in/output control device for a double-reach type automated warehouse. There wasn't.

What are the double reach fire types that are controlled by the present invention?

One shelf can be divided into two shelves, the front shelf and the actual shelf, where products can be stored individually. Products are stored in the order of the actual shelf and then the front shelf, so the manufacturing date of the product can be used as a key. When performing advance control, there are many cases where the product to be issued is stored in the actual warehouse, and another product is also stored on the shelf in front of it. The problem is that the product to be shipped is removed from the warehouse after the product is moved to another shelf, and this placement movement causes a deterioration in the efficiency of shipping due to double reach.

SUMMARY OF THE INVENTION An object of the present invention is to provide a warehousing/unloading control device that has a function of minimizing the frequency of placement movement and improves warehousing efficiency.

[Means for solving problems]

As a condition for advance delivery, the manufacturing date of the product is used as the key, and products with the same manufacturing date can be released in any order, not in the order in which they were received. The selection conditions for the selection conditions and the selection conditions for the shipping shelf at the time of shipping are selected as follows.

The selection conditions for the storage shelves at the time of warehousing are determined by prioritizing the shelves in the order of the shelves that do not need to be moved or have a high possibility of being moved at the time of warehousing, and the shelves that need to be moved. The conditions for selecting the shelves to be shipped are those that do not need to be moved, and the priority is given in the order of shelves that need to be moved, starting with the shelves that are superior when the shelves are received when the shelves are shipped. Determine selection conditions.

By determining the shelf that satisfies the highest priority condition for each selection condition among all types as the target type when loading and unloading, it is possible to minimize the frequency of placement changes during loading and unloading. , it is possible to improve shipping efficiency.

[Effect]

At the time of warehousing, information on the product to be stocked (type and date of manufacture) and information on the products in stock are searched for all types in order of priority selection conditions, and the first shelf that satisfies the selection conditions is selected as the optimal shelf for warehousing. Determine the receiving shelf.

When issuing goods, in the same way as when receiving goods, products in stock that have the same information as the product to be issued are searched for in the order of selection conditions with high priority, and the shelf that satisfies the selection conditions first is selected as the optimal item for shipping and is issued. I do.

As described above, by warehousing taking into account the unloading process at the time of warehousing, and by taking the necessity of placement movement and warehousing into consideration when leaving the warehousing, it is possible to minimize the frequency of placement movements when leaving the warehouse. .

〔Example〕

An example of the present invention is shown.

FIG. 1 is an overall configuration diagram, and at the time of warehousing, an operator inputs the type and manufacturing date of the product to be warehousing using the CRTI and keyboard 2. The input data is input to the warehousing control program 5 via the CRT input/output program 4 in the calculation system 3. The warehousing control program 5 follows the selection conditions of the warehousing shelf based on the input data and inventory data 6.
The optimum shelf for warehousing is determined and instructed to equipment 7 as the warehousing shelf.

The equipment 7 receives products into the storage shelves of the double reach dog breed warehouse 8. Further, when taking out the product from the warehouse, the operator inputs the type of product to be taken out using the CRT1 and the keyboard 2. The input data is input to the delivery control program 9 via the CRT input/output program 4 in the computer system 3. The shipping control program 9 determines the optimal shipping shelf for the product with the oldest manufacturing date among the same type of inventory as the specified product in the inventory data 6, according to the shipping shelf selection conditions, and sends the product to the equipment 7. Indicate as a shipping shelf. Equipment 7 takes out the delivery rack from the double reach dog breed warehouse Jiit 8.

In addition, if it is necessary to move the placement at the time of stocking, input the type and date of manufacture of the product stored on the front shelf of the product to be shipped into the warehousing control program 5, determine the shelf to which the placement should be moved, and then issue the product. The control program 9 instructs the equipment 7 about the source and destination shelves, and moves the double reach dog breed warehouse 8.

Fig. 2 shows the equipment layout of a double-reach type automatic warehouse. At the time of warehousing, when the warehousing conveyor 10 carries the products to be warehoused, the stacker crane 11 transfers them and transfers them from the computer system. The product is stored on the designated shelf 12. At the time of unloading, the stacker crane 11 transfers the products stored on the shelves 12 as instructed by the computer system, conveys them to the unloading conveyor 13, and the unloading conveyor 13 unloads the products. In addition, in the case of placement movement, the stacker crane 11 moves the product on the front shelf 14 specified by the computer system to the destination shelf 12 specified by the computer system, and then moves the product to the destination shelf 12 specified by the computer system. Issue 15 products that are in actual use.

Next, a method of selecting shelves at the time of warehousing and warehousing will be explained.

FIG. 3 shows the selection conditions of the storage shelf at the time of storage. The type of product is A and the product other than A is B, and the manufacturing date is centered around Y, with X being older than Y and Z being newer than Y. Therefore, when the type of product to be stocked is A and its manufacturing date is Y, the front shelf and the real right to it are set as a pair, and the inventory status of the front shelf and the real right, and when the real right has inventory, the product is Compare and judge the type and date of manufacture of the product. The determination conditions are set to a priority level of 1 to 4.

FIG. 4 shows a flowchart of the warehousing process.

It is determined whether the product to be stocked and the type to be searched satisfy the conditions of priority level 1, and when the conditions are satisfied, that shelf is determined as the optimal shelf for receiving J1. Also, if the condition is not satisfied, search for all types of shelves that satisfy the conditions, and if there is no shelf that satisfies the condition of priority 1 even after searching all the shelves, search with the condition of priority 2, The search is performed sequentially until a shelf that satisfies the following conditions is found, and the first shelf that satisfies the conditions is set as the optimal shelf for warehousing. If there is no shelf that satisfies the conditions even after searching for all types with all the conditions of priorities 1 to 4, it is assumed that there are no empty shelves and stocking is stopped.

FIG. 5 shows the conditions for selecting the shipping shelf at the time of shipping.

The definitions of type and manufacturing date are the same as in Figure 3.

Therefore, when the type of product to be shipped is A, search the manufacturing date of the product of type A in stock and find the earliest manufacturing date Y.
is calculated, and a comparative judgment is made for products of product type A and manufacturing date Y. The determination conditions are set to a priority level of 1 to 4. FIG. 6 shows a flowchart of the shipping process. First, it is determined whether product type A is in stock, and if it is not, it is assumed that there is no stock and shipping is stopped. When there is inventory, search for the oldest manufacturing date in inventory, determine whether the inventory satisfies the priority 1 condition, and search for inventory that satisfies the priority 1 condition. If there is no shelf that satisfies the condition, the search is performed using the priority level 2 condition, and the search is performed sequentially until the condition is satisfied, and the column that satisfies the condition first is set as the optimal shelf for shipping. When the optimal shipping shelf is determined, it is determined whether the optimal shipping shelf needs to be moved, and if necessary, the optimal receiving shelf at the time of goods receipt is determined based on the type of product to be moved and the manufacturing date. The same process as above is used to determine the destination shelf, perform the placement movement, and then issue an instruction for shipping.

As described above, by appropriately selecting the receiving and issuing shelves, there are many cases in which the goods are delivered with priorities 1 to 3 of the selection conditions of the receiving shelves, and there are cases in which the goods are delivered with priority 4, which requires a change in placement. Since the amount is reduced, it becomes possible to efficiently take out the warehouse.

〔Effect of the invention〕

According to the present invention, in a double reach type automated warehouse, when carrying out advance processing using the production date of a product as a key, it is possible to carry out warehouse delivery with high efficiency, thereby shortening one working time and reducing operating costs. effective.
