According to the present invention, there is provided a traversing carriage traversable along a traversing guide laid in a roll shop, and a lifting trolley mounted on the traversing carriage so as to be able to move up and down.
A traveling guidance guide laid on the lift truck so as to be connectable to a guidance guide laid in a multi-stage rack so as to extend in a direction perpendicular to the longitudinal direction of the traversing guide, and a guidance guide parallel to the multi-stage rack. A transfer guide laid on the lift truck so as to be connectable to the storage guide laid on the guide truck, a guide truck movably disposed on a travel guide of the lift truck, and the transfer guide and And a fixing device provided on the guide bogie so that the roll chock movable along the storage guide can be disconnected.

[0008]

Therefore, the traversing carriage travels along the traversing guide in a state where the chocks carried in from the mill yard are placed on the transfer guide and the chocks are fixedly connected to the guiding bogie by the fixing device, In the case where the transfer guide stops at the position where the traveling guide guide coincides with the guide guide at the bottom storage guide of the multi-tier rack where the chock should be stored, and the chock is stored at the bottom of the multi-tier rack, When the transverse trolley stops, the guide bogie moves on the travel guide and transfers to the guide, and the chock moves from the transfer guide to the storage guide in conjunction with the movement of the guide bogie, and the chocks move to the multi-stage rack. When the guide bogie is completely located in the lowermost stage, the guide bogie stops and the connection between the guide bogie and the chock by the fixing device is released. Return on the travel guide information from, storage working chocks to the bottom of the plurality of stages rack is completed.

In the case where the chock is stored in a required stage above the lowermost stage of the multi-stage rack, when the traversing truck stops, the lifting trolley rises with respect to the traversing truck, and the required stage of the multi-stage rack is raised. After the transfer guide is stopped at the position where the traveling guides coincide with the guides of the required stages of the multi-stage rack, the guide bogie moves on the travel guides and transfers to the guides. When the chock moves from the transfer guide to the storage guide in conjunction with the movement of the guide bogie, and when the chock is completely placed in the required stage of the multi-stage rack, the guide bogie stops and the guide bogie by the fixing device is stopped. The connection state between the vehicle and the chock is released. Thereafter, the guide bogie returns from the guide to the travel guide, and the lift bogie descends with respect to the traversing bogie to return to the original position.
