According to the present invention, the pallet storage capacity of the pallet storage unit can be more than doubled relative to the unit floor area.
Since the pallet storage shelves above the tier are fixed in a cantilever manner on the outer periphery, the supports on the inner periphery of the pallet storage can be omitted and the pallet storage can be placed as close to the inner periphery as possible. , the diameter of the circumscribed circle in the fan-shaped arrangement of pallet storage can be reduced to save space. In addition, since the inner peripheral end of the second and higher pallet storage shelves is slidably supported by the post on the pallet exchange mechanism side via a guide rail, the pallet storage can be held on both the inside and outside from the cantilever of the outside support. This provides support and prevents the pallet storage shelf from bending due to the shift of the center of gravity during pallet transfer, allowing for smooth pallet transfer.
Furthermore, the lifting mechanism is installed only on the pallet exchange mechanism side, thereby simplifying the device and reducing costs by unifying control.
