JPH01162607A - Delivering method for goods from automatic warehouse - Google Patents

Abstract

PURPOSE:To improve the operating efficiency of an automatic warehouse by grouping pallets on each shelf into two kinds, depending on the necessity of repeating the storage of goods to the warehouse, and continuously delivering goods from the warehouse for every group when the order of delivering goods from the warehouse is determined. CONSTITUTION:When the name and the quantity of goods to be delivered from a warehouse are input by an input/output terminal 21, the order of delivering goods from the warehouse is determined on referring to an inventory file 25. In this case, a shelf where a part required to be delivered from the warehouse is stored, is inspected for whether it is a consolidation shelf for which the repetition of storing goods to the warehouse is necessary or a single shelf for which the repetition of storing goods to the warehouse is not necessary, and the shelves are grouped into the consolidation and the single shelves and the numbers of shelves are registered, And the consolidation and the single shelves are continuously registered, separately from each other, in a command file for the delivery of goods from the warehouse, consequently, the delivery of goods from the warehouse is performed continuously for every group, so that the operating efficiency of the automatic warehouse concerned can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application 1] The present invention relates to a method for controlling warehouse delivery in an automated warehouse that handles a wide variety of products.

[Prior Art 1] An automated warehouse generally stores one load on one pallet (including containers and packets). In this case, the delivered pallet is transported to the destination using a forklift or the like. (Japanese Unexamined Patent Publication No. 61-203005) However, when handling a wide variety of products or small items, a single pallet is loaded with multiple items or multiple types of items. In this case, generally, once the goods are out, the necessary number or types of goods are picked, and the remaining goods are returned to the warehouse along with the pallets.

Furthermore, some warehouses have a mixture of pallets carrying one load (hereinafter referred to as single load pallets) and pallets carrying multiple loads (hereinafter referred to as mixed load pallets).

The present invention relates to such a warehouse.

[Problems to be Solved by the Invention] When there is a request for delivery of multiple pallets, the order of delivery is, for example, in the order in which they were received (first in, first out), and whether it is a single pallet or a mixed pallet. Depending on whether it is grooving or unloading, the method of grooving is not used.If the single load is a 6-single load, the work is to unload the single pallet with the entire pallet from the exit.If the load is a mixed load, only the necessary parts are taken out. The rest must be instructed to be restocked. If the order of unloading is not grouped by single loading or mixed loading, the operator performing unloading work will have to perform different operations depending on the contents of the pallets that are sequentially unloaded, resulting in inefficient unloading work. In particular, when the exit for a single pallet and the exit/re-entry exit for a mixed pallet are located at different locations, it is inefficient, as it requires the operator to move from place to place.

Note that the operator refers to, for example, in the case of a single pallet, a driver of a forklift that transports the pallet at the exit. In the case of mixed pallets, this refers to the worker who picks and gives instructions for restocking.

An object of the present invention is to provide an automated warehouse system with high operational efficiency.

rMeans for solving the problem] The above purpose is to group multiple pallets that have been requested to be delivered into single pallets and mixed pallets, to sequentially issue one of them, and then to sequentially issue the other one. This can be achieved by issuing the goods.

[Operation] According to the above, since single items are delivered to a single pallet and mixed items are delivered to a mixed pallet in succession, the operator performing the unloading work has to unload the single items from the exit. This can be done continuously, and the work of re-entering the warehouse after taking the necessary parts at the unloading/re-entering port for mixed items can also be performed continuously, so the unloading work is efficient.

[Example 1] Hereinafter, an example of the present invention will be described with reference to FIGS. 1 to 3.

FIG. 3 shows an example of an automated warehouse. The automated warehouse consists of a shelf group l having a large number of shelves for storing pallets, a stacker crane 3 that runs along this, a conveyor 8 that transports pallets between a transfer port 5 and a lower loading/unloading area, and a loading/unloading system. It consists of a terminal device (not shown) that issues commands, and a computer (not shown) that controls them.

Figure 2 shows the software configuration.

The user manually enters the name and quantity of the product to be shipped from the input/output terminal 21 (F22). The computer refers to the inventory file (F25), determines the shipping order (F23), and the shipping instruction file (F2).
6). The computer controls each device according to the delivery instruction file (F26). (F24).

FIG. 1 shows the processing flow of the shipping order determination program.

First, find out which shelf the relevant part is on and make a reservation for the shelf (in the case of one shelf or multiple shelves) that satisfies the quantity requested (F31). A check is made to see if the shelf stores a product type other than the requested product (or a quantity greater than the requested quantity) (F33).

When one shelf has different types or quantities other than those requested, it is called a mixed shelf, and in other cases it is called a single shelf. That is, a shelf having pallets that must be picked and re-entered is a mixed shelf. Based on this check, each group is divided into its shelf No.,
(F34.35) Next, in the delivery instruction file, a delivery instruction is registered so that mixed shelves are delivered consecutively as mixed shelves, and single shelves are delivered consecutively as single shelves. (F36) This delivery order determination program is executed in predetermined time units.

[Effects of the Invention] According to the present invention, since mixed items and single items can be grouped and removed from the warehouse, the efficiency of the shipping work can be improved.
