BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transport system capable of loading and unloading a load transported by a transport train onto a shelf, or vice versa, transporting the load from the shelf to the transport train. The present invention relates to a storage rack device.

[0002]

2. Description of the Related Art As a transfer and storage shelf device of this type, a load mounting portion having a load transfer means between a shelf and a load supporting portion of the shelf can be unwound and wound up on the transport train. Suspended by a rope so that it can be lifted up and down, and a shelf is erected on the side of the lifting path of the load carrying section below the traveling path of the transport train, and the shelf is set up by running the transport train and lifting the load carrying section. The load carrying section is adjacent to any load supporting section of the shelf, and the load transferring means of the load carrying section can transfer the load between the load supporting section and the load carrying section of the adjacent shelf. It is known to be composed.

In such a conventional transport and storage rack device configuration, it is necessary to suspend the load carrying section so that it can be lifted up and down on each of the many transport trains used as a whole of the equipment. Not only does this lead to a weight increase and a significant increase in the cost of the entire equipment, but it is also unstable because the load-carrying section that has descended to a prescribed level is suspended by a hanging rope, so that safe load transfer can be performed. It is also necessary to install a steadying means for the load carrying section on the shelf side. For this reason, the traveling of the transportation train and the lifting and lowering of the load carrying section are performed at the same time,
It is also not possible to reduce the cycle time of loading and unloading work. Further, since the lifting / lowering drive means for the load carrying section must be mounted on the transport train, there is a limitation in increasing the capability of the lifting / lowering drive means to speed up the lifting / lowering speed of the load carrying section. It was difficult to reduce the cycle time of loading and unloading work.
