Description

[Detailed Description of the Invention] Industrial Application Field The present invention provides a shelf having a plurality of compartment storage spaces, and a cargo delivery device that can travel along the shelf and transfer cargo between the compartment storage spaces. and
In particular, it relates to warehouse equipment that stores cargo stacked in multiple tiers in compartment storage spaces.

BACKGROUND ART Conventionally, in this type of warehouse equipment, cargo stacked in multiple tiers is separated from the tiers along a delivery route outside the warehouse, and it has never been seen that the items are separated from the tiers and carried out one by one within the warehouse. However, something similar to this has been proposed, for example, in Japanese Utility Model Application Publication No. 133502/1983. This relates to warehouse equipment for delivering or storing cargo via pallets, and includes a stacking section for stacking pallets at the end of a shelf, and a trolley that runs between this stacking section and a loading/unloading section. By stacking and storing the pallets that remain after only the cargo is carried out in the stacking section via a trolley, the process of returning the remaining pallets to the original storage space using the cargo delivery device is eliminated, and the operating rate of the equipment is improved. It is something that improves.

Problems to be solved by the invention In the above configuration, if the load is held in the stacking section instead of the pallet and the load is conveyed from the stacking section to the unloading section via the cart one step at a time, the load can be separated one step at a time. It can be carried out. However, with the above configuration, the cart must be reciprocated between the stacking section and the unloading section every time a load is transferred from the stacking section to the cart, and continuous unloading cannot be performed. Therefore, the continuous loading and unloading operation of the loading/unloading device is hindered, and the operating efficiency of the entire facility is reduced.

The present invention solves the above-mentioned problems and improves the operating efficiency of the entire equipment, and provides warehouse equipment that allows cargo stacked in multiple tiers to be separated from the shelves and transported one by one. The purpose is to

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a shelf having a plurality of compartment storage spaces, and a shelf that can travel along the shelf and transfers cargo between the compartment storage spaces. In a warehouse facility equipped with a cargo handling device capable of handling goods, a carry-out conveyor is provided across an end of the shelf and a carry-out section formed outwardly from the end of the shelf, and a carry-out conveyor is provided at the end of the shelf. The structure includes a stack unwinding device having a load receiving platform that moves up and down through the surface and a load holding section that holds the load above the load receiving platform.

Operation In the above configuration, the cargo delivery device transports the plurality of tiers of cargo stored in the divided storage space onto the cargo tray at the raised position of the cargo unloading device. Then, after the load on the upper stage is held in the holding section, the load receiving platform is lowered, and the load on the lower stage is placed on the carry-out conveyor and conveyed. Next, after raising the load receiving platform and supporting the load on the upper tier, the holding section releases the load, and if there are two or more tiers, the holding section further holds the load at the top of the upper tier. , the cargo tray is lowered and the cargo in the upper section is placed on the carry-out conveyor. In this way, the load in multiple stages can be stacked one by one on the carry-out conveyor after being separated by the stack-breaking device, and can be continuously sent to the carry-out section.
