Next, the conveyance operation of this embodiment will be described for the case where the conveyance container IO is conveyed from the uppermost corresponding floor of the vertical chain conveyor apparatus A to the uppermost corresponding floor of the vertical chain conveyor apparatus B.

The conveyance container 10, which is placed on the carry-in guide roller through the carry-in/outlet opened from the carry-in chute plate (none of which is shown), is supported at its collar by the rising hanger 29 of the vertical chain conveyor device mA. The chain gears 16.17 located at the top of the vertical chain conveyor A are conveyed upward and conveyed downward through the chain gears 16.17 located at the top of the vertical chain conveyor A, thereby reaching the discharge guide rollers 5.6 provided at the bottom of the vertical chain conveyor A. reach the corresponding position. Here, the unloading guide roller 5.6 is moved in the approach direction, and the transport container IO is supported by the unloading guide roller 5.6 at its collar, while the hanger 29 continues to descend.

The transport container l supported by the unloading guide roller 5.6
O is transferred to discharge guide rollers 39 and 40 provided at the upper end of the relay conveyor C. Here, a detection switch (not shown) is turned on, and each chain conveyor 33a, 34a at the top end of the relay conveyor C is in a standby state.
It is circularly driven in the direction of the arrow in FIG. As a result, one of each pair of support claws 47a, 48a, that is, the four support claws, moves to the uppermost position to support the flange of the transport container 10, and then each unloading guide roller 39.
40 is released from supporting the transport container 10, and the transport container 10 is transported downward by each chain conveyor 33a, 34a.

is transferred from each of the chain conveyors 33a, 34a to each of the chain conveyors 33b, 34b, and further conveyed downward. On the other hand, each of the chain conveyors 33a,
When the drive 34a returns to the standby state, its driving is stopped. In this way, the conveying containers 10 are successively conveyed downward by the respective chain conveyors 33, 34 and placed on the discharge guide rollers 37 provided at the lower ends thereof.

Then, by opening the carry-out port 11, the transport container IO is transferred to the carry-out chute plate 13, and the transport operation is completed.

Note that during downward conveyance by each chain conveyor 33, 34, if the conveying container 10 is already supported on the lower chain conveyor, the downward conveyance is interrupted and the conveying container 10 waits until the lower chain conveyor becomes empty. It becomes a stock state.

Further, since there is no particular difference from the conventional conveyance operation using only the vertical chain conveyor devices A and H, a description thereof will be omitted. Furthermore, since the carrying-in operation of the transport container 10 using the relay conveyor D is merely a reverse operation of the carrying-out operation using the relay conveyor C described above, the explanation thereof will also be omitted.

Note that the present invention is not limited to the above-mentioned embodiments, and for example,
It is not necessary to provide the carrying-out population 11 on every floor, and in this case, various components such as the carrying-out guide roller 38 attached to the cell are unnecessary, and many modifications can be made without departing from the technical idea. Can be done.
