Double floor 8 in lift cage 16 and transfer machine 1
Since the structure of No. 2 is the same as that of the loading / unloading berth 3 of the first embodiment, the operation of this embodiment is almost the same as that of the first embodiment. However, since the lift cage 16 moves up and down, the actual vehicle pallet 10a can be transferred at any position on the double floor 8 of the carriage 1. As a result, the position of the double floor 8 of the trolley 1 may be aligned with the position of the parking shelf 2 for entering or the parking shelf 2 for leaving, and the lift cage 16 and the actual vehicle pallet 10a may be delivered. Although the loading / unloading berth is provided at the end of the parking shelf 2 in this embodiment, it can be installed not only at the end but also at any place. This makes it possible to freely set the vehicle entry location.

[0021]

As is apparent from the above description, according to the present invention, by providing the elevator-equipped carriage, it is not necessary to provide the carriage for each stage of each parking rack. Further, since the parking shelves, the trolley lifting device, and the loading / unloading berth have double floors, and empty pallets can be stored on the lower floor, it is not necessary to provide a warehouse for empty pallets. Further, since the empty pallets are replaced at the same time as the actual vehicle pallets on the upper floor, the time for handling the empty pallets does not affect the loading / unloading time, and the waiting time for loading / unloading can be shortened. Further, by providing the lift, the boarding position of the vehicle can be freely set.
