Abstract

PURPOSE:To provide an automated warehouse which can increase carrying-in and -out capacity step by step as necessary and can be designed economically so as to own only relatively small carrying-in and -out capacity which is necessary at present. CONSTITUTION:This automated warehouse is provided with a rack structural body 2 in multiple floor layers which are provided in each floor with racks for storing articles and passages where a battery-driven carriage 1 travels, a lift table 4 which moves the battery-driven carriage 1 in a vertical direction from one layer to another layer of the rack structural body 2, the battery-driven carriage 1 which is provided with a picking function, and battery chargers which are installed on the lift table 4 and at the waiting positions on the passage. It is thus possible to increase the carrying-in and -out capacity of the automated warehouse step by step by changing the number of the carriages and lift structure. Besides, it is also possible to charge the batteries of the carriage 1 in the course of stand-by with no work.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automated warehouse comprising a shelf structure and a battery-driven electric carriage.

[0002]

2. Description of the Related Art The most common automatic warehouse of the prior art comprises shelves and stacker cranes. In relatively recent automated warehouses, the shelves are divided into multiple floors, and electric trolleys that receive power from the trolley wire through contacts are run on each floor. The electric trolleys run horizontally and the electric trolleys vertically There is also a configuration in which the work is moved by the movement of the lifter.

[0003]

In the automatic warehouse using the above-mentioned conventional stacker crane and electric trolley, it is very difficult to increase the loading / unloading capacity after installation. As a result, automated warehouses have been uneconomically designed to have large loading and unloading capacities that may be useful in the future, even though they are unnecessary now.

The present invention solves the above-mentioned conventional problems, and it is possible to increase the warehousing and unloading capacity in stages, and therefore, it is economical to have only the relatively small warehousing and shipping capacity currently required. The purpose is to provide an automated warehouse designed.

[0005]

In order to achieve the above object, the automatic warehouse of the present invention comprises at least one battery-powered electric cart having a picking function for moving articles between a shelf and an electric cart. A multi-tiered shelf structure having shelves for storing articles in stock and a passage through which the electric carriage travels, and at least one lift table for moving the electric carriage from floor to floor of the shelf structure; And a charger installed at a standby position of the electric carriage on the lift table and on the passage.

[0006]

By changing the number of the electric trolleys having the above-described construction or the construction of the lift, the loading / unloading capacity can be gradually increased. In addition, the electric trolley can charge the battery during standby when there is no work.

[0007]

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 diagram showing a configuration of an automatic warehouse of the present invention. Reference numeral 1 is a battery-driven electric carriage for carrying workpieces to be loaded and unloaded, and a charging power source contactor (not shown) for charging a mounted battery. And a picking device (not shown) for putting the work in and out of the shelf. Reference numeral 2 denotes a shelf structure, and a shelf for accommodating a work and an aisle through which the electric carriage 1 travels are formed on each floor of a multi-story structure. 3 is a lift, 4 is a lift table which moves up and down in the lift 3, and is an electric carriage 1
Is moved from one floor to another floor of the shelf structure 2 formed in multiple layers. The electric trolley 1 moves vertically by a lift table 4, and moves horizontally in a passage in the shelf structure 2 by battery drive. In addition, the electric trolley 1 is stopped on the lift table 4 or in the standby position in the passage when there is no work, and at that time, the charging power source (not shown) installed at that location is the charging power source described above. The battery is being charged by bringing the contacts into contact.

FIG. 2 is an explanatory view when the loading / unloading capacity of the automatic warehouse of the present invention is changed stepwise. Shelf structure 2 is 5
It is on the floor. A is the case where the capacity is the lowest, and since there is only one electric trolley 1, it becomes impossible to deal with it as the number of warehousing / delivery times and the number of workpieces increase. In that case, there are two electric carriages 1 as in B. Furthermore, if the number of jobs increases, C
As described above, the number of electric carts 1 is increased, and further the number of lifts 3 is increased.

[0009]

As is clear from the above description, the automatic warehouse of the present invention can increase the warehousing and unloading capacity in stages, so that only the relatively small warehousing and loading capacity currently required is required. It is economical because it can be made and the capacity can be increased according to the actual situation.
