(A) Carrying-in operation The lifting platform 14 of the carrying-in container elevating mechanism 8 has descended to the lowest position leading to the external carrying-in conveyor 9 shown in FIG. Benefits are given in the positions shown.

In this state, when the container 5 is sent in from the outside via the external carry-in conveyor 9, the roller conveyor 21
starts rotating, and the container 5 is taken onto the back-loading table 14. When the loading of the container 5 is completed, the roller conveyor 21 stops rotating, and the lifting platform 14 starts an upward movement. During this upward movement, the tapered roller 20b acts to urge the container 5 toward the pusher 23, so that the container 5 is maintained at an appropriate position pressed against the pusher 23. Furthermore, the positional shift in the forward direction is monitored by a sensor (not shown). Note that during the upward motion of the lifting table 14, the roller conveyor 21 may continue to be rotated to continue urging the container 5 toward the stopper 22, and in this case, the above-mentioned sensor can be omitted.

When reaching the target shelf, the lifting platform 14 stops, and then the pusher 23 moves forward. By this operation, the container 5 is loaded onto the temporary loading shelf 44. After loading the container 5, the pusher 23 returns to its original position.
The elevator platform 14 descends to the lowest position.

The containers 5 loaded on the temporary carry-in shelf 44 are then taken into the picker 6 and stored on the target shelf 4.

(B) Carrying out operation When the data of the container 5 to be carried out is transmitted from the main computer (not shown), the picker 6 of the shelf where the container 5 to be carried out is stored takes out the target container 5 from the shelf 4 and carries it out. Load it on temporary storage [72]. On the other hand, in the unloading container elevating mechanism 47, the elevating table 54 starts moving up and down toward the target shelf, and stops when it reaches the target shelf. In the unloading temporary storage shelf 72, when the container 5 is loaded from the picker 6, the unloading pusher 76
As shown by the solid line in FIG. 8, the container 5 is waiting at a position that does not interfere with the loading of the container 5. When the lifting platform 54 arrives at the shelf where the container 5 is waiting, the pusher 76 advances as shown by the imaginary line in FIG.
loaded on top.

At this time, the roller conveyor 61 on the lifting platform 54 is driven in a rotational direction that urges the container 5 toward the stopper 62 on the rail 7 side on which the picker 6 runs, so that the container 5 comes into contact with the stopper 62. , and stopper 64
The guide piece 66 is positioned at an appropriate position regulated by the step and the step of the guide piece 66. When the pusher 76 returns to its original position. ,
The lifting platform 54 carrying the container 5 starts its lowering operation and descends to the lowest position leading to the external discharge conveyor 48 .

Since the roller conveyor 61 continues to be driven during the lowering operation, the container 5 on the lifting platform 54 is maintained at an appropriate position without being displaced. When the elevating table 54 reaches the lowest position, the roller conveyor 61 is switched to forward rotation drive, and the container 5 on the elevating table 54 is ejected from the elevating table 54 by the action of the roller conveyor 61 and transferred to the external carrying conveyor 48. It is sent to the outside via

(Effects of the Invention) As described above, according to the present invention, the carrying-in container lifting mechanism and the carrying-in temporary storage shelf, or the carrying-out container lifting mechanism and the carrying-out temporary storage shelf are aligned in the same line as the shelves in the storage area. Because of this structure, the required area for installing the entire device is small, and the device can be installed efficiently in a limited space.
