In this conventional example, when the link plate is driven to move the target stocker shelf (article) to the take-out device, the stop position may be uneven due to inertial movement, manufacturing accuracy, assembly accuracy, elongation of the link plate, etc. , the removal operation by the removal device cannot be performed smoothly and accurately. Particularly when the weight of the stocker shelf is large or the entire stocker is large, the irregularity in stopping due to inertial movement becomes severe.

Purpose of the invention The purpose of the invention is to provide a rotary shelf facility whose stopping position can be corrected immediately after stopping.

Structure of the Invention In order to achieve the above object, the carousel equipment of the present invention includes a pair of upper and lower annular rails, a plurality of cargo storage bodies that are guided by these annular rails and are movable along an annular path, and a carousel along the annular path. A rotating shelf is formed by a driving body which is movably arranged and connected to the load storage body, and a transfer machine is disposed at a suitable position outside the rotating shelf, and a circular path is arranged near the transfer machine. A positioning device is provided inside, which acts on the drive body to position the load storage body in the moving direction.

According to this configuration, after the drive body is stopped and the target cargo storage body is opposed to the transfer machine, the positioning device is actuated to act on the drive body, thereby determining the moving direction of the cargo storage body. Position correction and positioning can be performed.

Bracket 51 and both link plates 4 attached to
a cylinder device 52 disposed between the free end of 9;
It consists of a solenoid valve 53 for cylinder operation, and the clamp piece 50 is moved by the operation of both cylinder devices 52.
It is configured to move in and out while swinging with respect to the moving path of the chain 24 disposed below. At this time, both clamp pieces 50 are configured to move toward each other by swinging in the direction of approaching each other, and to come into contact with both rollers 54 forming one pitch from the outside.

Next, the operation of the above embodiment will be explained. In the rotating shelf 1, the forward and reverse rotational force of the geared motor 29 is transmitted to the drive shaft 27 via the endless transmission 30,
The chain 24 is moved forward and backward via the drive wheel body 28. As a result, the load storage body 4 integrated with the chain 24
is supported and guided by both rails 11 and 12 and moves forward and backward, and then the target cargo storage body 4 can be stopped facing the transfer machine 39. Then, by the transfer machine 39, the case 1 is transferred between the cargo storage body 4 and the cargo receiving platform 42.
8 is exchanged. Note that the movement of the load storage body 4 is performed separately in both stages.

When the target cargo storage body 4 is stopped facing the transfer machine 39, the stopping position is not necessarily constant, and if it is shifted, the transfer by the transfer machine 39 cannot be carried out smoothly and accurately. For this purpose, the positioning device 45 is activated immediately after stopping. That is, both clamp pieces 50, which are in the retracted position shown by the imaginary lines in FIG. By bringing both the clamp pieces 50 into contact with and clamping the two rollers 54 located from the outside, it is possible to correct the variation in stopping and mechanically lock the stop.

In the above embodiment, the intermediate frame 9 in the support frame 5
Although one stage is shown as a whole with one stage, it may be provided with two or more stages to form a larger number of stages, or may be omitted and a single stage format is shown.

Effects of the Invention According to the rotating shelving equipment of the present invention having the above configuration, after the driving body is stopped and the target load storage body is opposed to the transfer machine, the positioning device is operated to move the target load storage body to the transfer machine. It is possible to perform position correction and positioning in the moving direction of the body, and as a result, it is possible to correctly face the load storage body that was unevenly aligned at the time of stoppage to the transfer machine, so that the transfer work by the transfer machine can be carried out at all times. Can be performed smoothly and accurately. Furthermore, this makes it possible to easily increase the overall size, and there is no need to be so concerned about various precisions, elongation, etc. By providing the positioning device inside the annular path, dead space can be used effectively and the surroundings of the transfer machine can be simplified. In addition, by having the positioning device act on the drive body, no load is applied to the connection between the load storage body and the drive body during positioning, and a suitable connection can be maintained for a long period of time. The device itself can be made smaller.
