By the way, when a completed vehicle is stored in such an automatic warehouse facility, keeping the vehicle always in a forward-movable state enables smooth loading and unloading. For example, when the vehicle is placed on the pallet and the pallet is loaded and unloaded, the vehicle can always be driven forward regardless of whether the vehicle is placed on the pallet or when the vehicle is separated from the pallet.

On the other hand, since the carriage 9 travels in one direction (counterclockwise in the illustrated example) along the traveling path 8, each corner 8a toward the automatic warehouse 1 or the delivery conveyor 3 is provided.
When traveling 8b, the carriage 9 is turned over 180 degrees at each of the corners 8a and 8b in any case. For this reason, even if the driver's seat a of the vehicle A is placed on the trolley 9 toward the front in the transport direction of the warehousing conveyor 2, the vehicle A is turned over 180 degrees when passing through the corner portion 8a on the warehousing side. When entering the automated warehouse 1 from the rear part of A, the driver's seat a of the vehicle A is placed in the automated warehouse 1 when it is placed on the trolley 9 from the rear part of the vehicle A and passes through the exit side corner portion 8b. Will be flipped towards. Therefore, there is a problem that the transfer conveyor 3 is transferred from the rear part of the vehicle A.

The present invention was devised to effectively solve the above problems.

[0008] It is an object of the present invention to provide an automatic warehouse facility capable of entering and leaving a vehicle while always maintaining a posture in which the vehicle can be driven forward.

[0009]

The present invention has a closed-loop running path for guiding the travel of a truck between an automatic warehouse and a loading / unloading device, and allows the truck to run in one direction along the running path. After turning the bogie along each corner of the traveling path, in an automatic warehouse facility for loading and unloading a vehicle placed on the trolley, the trolley is rotatably supported on the trolley and the vehicle is loaded and unloaded. Of a vehicle mounted on the turntable according to a change in the turn angle of a turntable having a conveyor for turning, and a trolley that turns along one of the corner portions on the loading / unloading side formed on the traveling path. The turning angle adjusting means adjusts the turning angle of the turntable so that the driver's seat is opposite to each other on the entrance side and the exit side.

[0010]

As described above, the turning angle of the turntable on the carriage traveling along one of the corners on the entry / exit side is such that the driver's seats of the vehicles placed on the turntable are on the entry device side and the exit device side with respect to each other. Since the vehicle is adjusted so as to be reversed, it is possible to reverse the vehicle transferred from the warehousing device to the dolly and transfer it from the dolly to the unloading device. Therefore, the vehicle can be loaded and unloaded in such a state that the vehicle can always be driven forward.
