However, there is another drawback to providing power equipment to each storage shelf as follows.

First, it is necessary to separately prepare a space for storing the power equipment in the storage shelf, which makes the structure of the storage shelf larger and more complicated. Furthermore, since there are a large number of storage shelves, the wiring structure for supplying power to many of the power equipment becomes complicated, and a large number of the roller conveyor drive control devices are also required.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a mobile loading/unloading device that can transfer containers even to storage shelves without power equipment.

[Summary of the invention]

The present invention is a mobile system in which a container or pallet loaded with cargo is placed on a movable shelf running on a track, and the container or pallet is transferred between a plurality of storage shelves arranged along the track. In the loading/unloading device, the movable shelf is provided with a drive device for running on a track and for transferring containers or pallets, and the drive device of the movable shelf drives the transfer device on the storage shelf to each of the storage shelves. A power transmission mechanism is provided, thereby making it possible to carry out the transfer work without providing a power source on the storage shelf side.

[Embodiments of the invention]

An embodiment of the present invention is shown in FIG.

In FIG. 2, 4 is a pole mat, 5 is a container operating arm installed close to the top of the pole mat 4, and 6 is a container operating arm installed near the top of the pole mat 4.
