Is rotated, and the locking tool 42 laterally moves larger than the lateral movement amount of the support body. The support endless rotation chain 33a
The connection position with respect to (33b) is set at a position biased to the lower side in the traveling direction, and at this time, the support body 41 projects further outward than the front and rear end edges Li of the mounting portion 29, Since the locking tool 42 relatively moves to the upper side in the traveling direction of the support body 41, as shown in FIG. 7, it is projected to the transfer projection position.

Furthermore, the endless rotating chain 33a (33b)
When is rotated, the locking tool 42 retreats and descends to the lower unlocked position along the arcuate path portion, and when further rotated,
The electric motor is moved to the inward side along the lower path portion, and is moved to the standby position where the locking tool 42 and the support body 41 are retracted inward of the front and rear end edges Li of the mounting portion 29. The driving of M3 is stopped. Detection of moving to the standby position is
This is performed by the photoelectric sensor 47.

When the container C is loaded / transferred from the storage section 1 or the article loading / unloading section 4 onto the loading section 29, the operation reverse to the above-described operation, that is, the transfer locking from the standby position is performed. Transfer is performed by moving to the position. At this time, when the container C is loaded and transferred in the locked state, the support body 41 is located inward of the front and rear end edges Li of the mounting portion 29 even when the container C is moved to near the end of the upper linear path portion. Will be located on the side, and further, the operated portion 47 contacts the unloading fixed contact portion 46, and
2 moves relative to the traveling direction on the support body 41, and the mounting portion 2
The container C can be carried in to near the end of the container 9 (see FIG. 7).

The respective endless rotation chains 33a, 33b and the respective locking members 42 are provided so as to transfer the articles to the storage section 1 or the article carrying-in / out section 4 located on the opposite sides, in either the front or rear direction. Also, the article transfer operation can be executed.

The article carrying-in / out section 4 is operated by an operation command on the basis of detection information from the rotary encoders, photoelectric sensors, etc., to move up / down electric motor M1, lateral movement electric motor M2, and article transfer electric motor M3. Each of the storage units 1 is provided with a control unit 49 as a control means for driving and controlling each of the storage units 1. The control unit 49 corresponds to each of the storage units 1 and an operation unit 50 for instructing operation contents and setting storage unit designation by human operation. A display unit 51 and the like for displaying the name of each component and the number of components stored in each container C are provided.

When the container C is loaded into the designated storage section 1, the operation section 50 issues an instruction to transfer the container C through the work loading section 4b of the article loading / unloading section 4. After being placed at a predetermined position of the placing section 4a, the lifting electric motor M1, the lateral movement electric motor M2, the article transfer electric motor M3, etc. are activated. Then, the article transfer device 7 moves to a location corresponding to the transfer placement section 4a to transfer the container C, and then moves to the designated storage section 1 to be stored in the storage section 1. Transfer container C,
The operation ends. When the stored container C is unloaded, the container C is unloaded to the transfer placement section 4a by the operation reverse to the above operation.

In this storage device, the work of loading and unloading containers (articles) can be performed from the lateral one side outside of the storage shelf. For example, when a plurality of such storage devices are arranged in parallel, As shown in FIG. 8, another storage device can be arranged in the short width direction (front-rear direction) in close proximity to each other and can be arranged in a space-saving state as much as possible.

[Other Embodiments] (1) In the above-mentioned embodiment, the loading / unloading section 4a is composed of a plurality of rollers Ro in which the article loading / unloading section 4 is freely rotatable.
However, as shown in FIG. 9, the container C
It may be configured by a mounting table 52 that simply mounts and supports. Further, as shown in FIG. 10, the storage shelves 2A,
An article placement section 53 of a part of the storage section that is located on the lower side of the 2B and on the lateral side is an operation position where the article transfer apparatus 7 can take in and out and the container C can be carried in and out by an operator. The storage shelves 2A and 2B may be configured to be slidably movable to and from the retracted position where the storage shelves 2A and 2B are retracted inward in the lateral direction.

(2) In the above embodiment, the length of the elevating table 5 in the longitudinal direction is set to be longer than the lateral width of the storage shelves 2A and 2B by a predetermined distance, and is longer than the lateral side surface of the storage shelves. Although the case where they are arranged so as to project laterally outward has been illustrated, instead of such a configuration, the horizontal length of the elevating table 5 is substantially equal to the lateral width of the storage shelves 2A, 2B. The article carry-in / out section may be configured by using the storage sections that are provided so as to be the same and are located on the side of the lateral end of the storage rack.

That is, as shown in FIG. 11, with respect to the structure of the storage rack in the above-mentioned embodiment, the extension shelf portion is provided at a position corresponding to both the front and rear outer sides of the lateral outward projecting portion 5A of the elevating table 5. 54 is provided, and the extension shelf portion 54 is provided with a column 8a only at the side end portion thereof on the side opposite to the ascending / descending path of the ascending / descending table 5 (the front and rear ends of the storage device). Further, the storage shelves 2A and 2B are provided so as to be slightly deviated to the outer side in the front-rear direction from the columns 8 located on the opposite side of the elevating passage.

On the lower side of the extension shelf portion 54, in the storage portion where the article carrying-in / out section 4 is formed, the mounting table 55 on which the container B is stored and mounted is at the storage position where the articles are stored and stored. It is configured to be slidable over an article loading / unloading position where the article can be loaded / unloaded by protruding laterally outward.

With this structure, the space above the article carry-in / out section 4 can be effectively used as a storage section, and an efficient storage configuration with no wasted space can be realized.

(3) In the above-described embodiment, the elevating table is configured to project laterally outward only to one side with respect to the storage rack.
As shown in FIG. 12, the elevating table 5 is configured to project laterally outward at both lateral sides of the storage shelves 2A and 2B.
The article carrying-in / carrying-out section 4 may be provided on both side portions in the front-rear direction of the respective outer protruding portions 5A, 5A.

(4) In the above embodiment, the case where the storage shelves are provided on both the front and rear sides of the lifting table has been exemplified, but the storage shelves may be arranged on only one side in the front and rear direction.

(5) In the above embodiment, a container for storing a plurality of parts is illustrated as an example of the article, but the container is not limited to the container, and may be a box body having a predetermined shape or a product having a predetermined shape.

It should be noted that reference numerals are added to the claims to facilitate the comparison with the drawings, but the present invention is not limited to the configurations of the accompanying drawings by the entry.
