EXAMPLES Hereinafter, examples illustrating the present invention will be specifically described.

In the automatic warehouse apparatus 10, the rotary racks 11, ... Are racetrack type as a whole, and the storage items 12, such as cardboard boxes and containers, are placed on the stands 12 ,.
... can be placed and rotated in both directions. The storage unit 14 includes a plurality of stages (6 in the figure) of the rotary racks 11 ,.
Step) Stacked vertically.

The loading elevator 15 is provided at one end of the storage unit 14 and receives and raises the stored items 13, ... Which are carried by the roller type loading conveyor 16, and is placed on one of the rotary racks 11 ,. Put. The carry-out elevator 17 is provided at the other end of the storage unit 14, receives the stored items 13, ... From the rotary racks 11, ..., Lowers them, and places them on a roller-type carry-out conveyor 18 and sends them out.

The loading elevator 15 vertically has four chains 20, ... At the left, right, front, and rear of an elevator space 19 through which the stored items 13 pass, and these are driven in cooperation with each other. Shelf boards 21, ... Are attached to each chain 20, .. One shelf board 21 is attached to the left two chains, and another shelf board 21 is attached to the right two chains. Is used to form the pedestals 22, ... In the up-and-down space 19, and to support the lower ends of both sides of the stored article 13 to raise them. In addition, the shelf plate 21 that has reached the upper end
Goes down outside the ascending / descending space 19 and faces downward.

In front of the ascending / descending space 19, pushers 23, ... Composed of air cylinders are provided at the positions of the carry-in conveyor 16 and the carousels 11 ,. Or from the base 22 onto the carousel 11 by pushing.

The carry-out elevator 17 is the carry-in elevator 1.
The configuration is almost the same as that of No. 5, and only the operation direction of the chain and the direction of the pusher are opposite, and thus detailed drawings and description are omitted.

The automatic warehouse apparatus 10 is constructed as described above and operates as follows under the control of a computer (not shown).

Storage items 1 sent by the carry-in conveyor 16
3 is the base 2 of the elevator 15 for loading by the pusher 23.
Can be placed on 2. Next, the elevator 15 raises the base 22 by one step, and places the next stored item 13 on the base 22 below the conveyor 22 from the conveyor 16. Repeating this, storage unit 1
The items to be stored are placed on all the bases 22 corresponding to the respective stages of the carousel 11 ,. In parallel with these operations, each of the carousels 11, ... Rotates and positions the empty stand 13 at the position of the loading elevator 15. Next, the pushers 23, ... Operate, and the storage items 13, .. At the same time, the next storage item 13 is placed on the bottom table 22 from the conveyor 16.

In this way, each carousel 11 of the storage unit 14,
The storage item 13 is placed on the storage device, and the computer stores information about which storage item 13 is stored at which position.

When taking out the specified storage item 13,
The rotary racks 11, ... Are rotated and moved, and the stored items 13 are moved to the unloading elevator 17 position. When the elevator 17 is operated and the empty base is positioned in front of the storage item 13, the base is stopped and the storage item 13 is placed by the pusher.
Further, the elevator 17 is operated, and when the stored item 13 reaches the lower end, it is placed on the carry-out conveyor 18 with a pusher.

The above-described operation is performed by this automatic warehouse apparatus 1.
This is an example of 0 operation, and various other operations can be performed. That is, as described above, the warehousing can be carried out one place at a time, or two or several places at the same time, in addition to carrying out all the carousels simultaneously. As for the warehousing, instead of taking out one place at a time as described above, it is possible to place the warehousing from two or all carousels on the elevator at the same time.

In the illustrated example, the elevator has a lift space of 1
At a location, a plurality of pedestals are continuously raised or lowered among them, but a hoisting space is annular, and a plurality of pedestals are endlessly rotationally moved in this (not shown)
Can also be In this case, since the stored items can be moved upward and downward by the one-way operation, it is possible to select the height of the carry-in / carry-out conveyor as the intermediate height of each carousel in the storage unit.

Further, in the illustrated example, one conveyor is connected to each elevator, but two or more conveyors may be vertically stacked on one elevator. This makes it possible to simultaneously transfer two or more stored items between the conveyor and the elevator as well as transfer of stored items between the elevator and the carousel.

Needless to say, the loading and unloading elevators can be provided at any position around the storage section. Further, the number of elevators provided around one storage unit is also arbitrary.

[0024]

As described above, in the automatic warehouse apparatus of the present invention, since the elevator has a plurality of pedestals continuously and it is possible to continuously raise or lower the stored items, it is possible to use the conventional warehouse. After raising or lowering one stored item, there is no wasteful operation of returning to the original position in the empty state, and it is possible to carry out storage and retrieval very efficiently. Therefore, while minimizing the number of elevators installed, reducing the installation area and cost,
The waiting time for loading and unloading can be reduced.

Further, when an elevator having a plurality of bases endlessly and capable of moving stored items upward and downward by one-way operation is used, the installation height of the carry-in / carry-out conveyor can be arbitrarily selected. This will increase the flexibility of arranging the entire warehouse.

Further, if one elevator has two or more conveyors, the efficiency of loading and unloading can be further improved, and the increase of the installation area and the cost can be suppressed to a small extent.
