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.

目的とする。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.

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.

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.
