Description of the Related Art Conventionally, as this type of apparatus, for example, a horizontal rotary shelf type sorting apparatus as disclosed in Japanese Utility Model Laid-Open No. 61-110630 has been provided. In this conventional structure, a large number of shelf frames are connected endlessly and movably supported on a horizontal circulation path, and a plurality of upper and lower shelves are vertically rocked on each shelf frame via horizontal axes. It is movably installed.

Articles are individually or simultaneously loaded onto each shelf of each shelf frame by a plurality of upper and lower loading devices provided outside the horizontal circulation path. The articles supported by the shelves are discharged individually or all at once by operating a plurality of upper and lower cylinders provided inside the horizontal circulation path to tilt and swing the shelves.

[0004]

In the above-mentioned conventional structure, when the articles are simultaneously put into the shelf frame and the articles are simultaneously discharged from the shelf frame, a plurality of loading devices and cylinders must be operated in synchronization. The control becomes complicated, and the provision of a plurality of charging devices and cylinders makes the overall structure complicated and expensive. Further, due to the frictional resistance of the article acting on the shelf frame, the loading by the loading device acting on the outside of the shelf frame and the sliding discharge by the inclination of the shelf plate may not be performed sufficiently smoothly. Moreover, since the operation amount such as the inclination angle is determined by the stroke of the cylinder, when the operation amount is increased, the cylinder or the like becomes large, and the installation becomes unreasonable or expensive. The cylinder requires an expensive air source and may not be used in an environment such as a freezer.

An object of the present invention is to always and reliably carry out simultaneous loading and unloading of articles to and from storage shelves with a simple structure and control, and a sufficient working amount (stroke) without increasing the size. In addition, the rotary shelving equipment can be set arbitrarily and can be used in a freezer or the like with an inexpensive structure.

At this time, the lowering 70 of the lower feeding device 54 is temporarily stopped. In addition, the delivery conveyor 65 is driven,
Therefore, the delivered tray 9 is delivered to the next process by the delivery conveyor 65. Then, when the tray 9 on the delivery conveyor 65 comes out of the receiving device 50, the lower feeding device 54 is moved down again, and the next lower tray 9 is transferred to the delivery conveyor 65.

By repeating such an operation, the tray 9 group that has been received by the receiving device 50 is sequentially transferred from the lower stage to the delivery conveyor 65 and is delivered to the next process.
Then, when the receiving device 50 has no tray 9, the tray 9 group of another storage shelf 20 is received by the receiving device 50 in the same manner as described above.
Are issued all at once.

As described above, the warehousing operation can be performed, and the warehousing operation can be performed by operating the warehousing device 30A in the same manner. That is, the tray 9 conveyed to the lower part of the supporting device 50A by the warehousing conveyor 65A is lifted upward by both supporting frames 59A which rise 70A outside the end of the warehousing conveyor 65A and is supported by the article supporting portion 60A. It
Then, by repeating such operations, the tray 9 conveyed by the storage conveyor 65A is sequentially lifted by both the support frames 59A that are raised 70A and is supported by the article support portion 60A.

When the support device 50A supports a predetermined number of trays 9, before and after this, an empty storage shelf 20 that does not store the trays 9 is stopped facing the support device 50A. In this state, the storage device 30A is actuated, and the forward pusher 30A simultaneously pushes the tray 9 group supported by the support device 50A together and transfers it to the receiving frame 24.
The groups can be stored in the article storage unit 25, thereby completing the simultaneous loading of the trays 9 into the storage rack 20.
