BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a parking system for loading and unloading a vehicle mounted on a pallet, and more particularly to a measure for improving the efficiency of loading and unloading.

[0002]

2. Description of the Related Art Generally, in a parking device for loading and unloading a vehicle on a pallet, for example, as disclosed in Japanese Utility Model Laid-Open No. 3-130865, when a vehicle is loaded, the vehicle enters and exits a loading / unloading port. The arriving vehicle is delivered to an empty pallet on the elevator pedestal, and the elevator is lowered to the traveling vehicle waiting on the predetermined parking floor to deliver the unloading vehicle together with the pallet to the traveling vehicle. It is designed to drive to the parking shelves and store the incoming vehicles together with the pallets in the parking shelves.

On the other hand, when the vehicle is to be unloaded, the traveling vehicle is moved to the intended parking rack, the unloading vehicle is received from the parking rack together with the pallet, and the traveling truck is moved to the elevator stand in the waiting state of the elevator. The pallet is moved and delivered to the lift table together with the pallet, and the lift table is raised to the entrance / exit opening to exit the exit vehicle from the entrance / exit opening.

There is also a parking device of a system in which an in-vehicle pallet is conveyed and delivered by a conveyor system instead of traveling a traveling carriage.

[0005]

However, in the parking apparatus for transporting the vehicle-mounted pallet by the above-mentioned carriage traveling method, the next carriage is carried out unless the traveling carriage is emptied and the traveling carriage is empty. However, during this time, the efficiency of entering and leaving the warehouse becomes poor because of waiting for entering and leaving.

[0006] Similarly, even in a parking system that conveys vehicle-mounted pallets by a conveyor system, the next loading and unloading cannot be performed unless the previous loading and unloading is completed and the conveyor is emptied. Waiting for the delivery of goods will reduce the efficiency of entry and exit.

The present invention has been made in view of the above points, and an object of the present invention is to convey an on-vehicle pallet by the latter conveyor system described above and divide the conveyor into parking shelves independently. By driving it, multiple vehicles can be loaded or unloaded at the same time, or at the same time, loading and unloading can be performed at the same time to eliminate waiting for loading and unloading, and improve the efficiency of loading and unloading. Especially.

[0008]

In order to achieve the above object, the present invention is directed to a parking device for loading and unloading a vehicle by mounting it on a pallet, and has taken the following solving means.

That is, the solution means of the present invention is to provide a moving path in the parking section for moving the pallet on which the vehicle is mounted at the time of loading and unloading. Further, a plurality of parking shelves for storing vehicles are provided along the moving path. Further, a transport means for transporting a pallet carrying a vehicle at the time of loading and unloading is provided on the moving path.
In this case, the transport means can be independently driven corresponding to each of the parking shelves, and a plurality of first conveyors that are independently drivable corresponding to the parking shelves and sequentially transport the pallets along the moving path. And a plurality of second conveyors for transporting the pallet in a direction orthogonal to the moving path. Also,
A third conveyor that conveys the pallet in a direction orthogonal to the movement path is provided on each of the parking shelves so as to be independently drivable, and the pallets are delivered to each other by the cooperation of the third conveyor and the second conveyors of the conveying means. It is characterized by doing so.

[0010]

With the above-described structure, in the present invention, the pallet on which the warehousing vehicle is mounted is sequentially fed to the target parking rack along the moving path by the plurality of first conveyors of the transfer means, and corresponds to the parking rack. By the cooperation of the second conveyor and the third conveyor of the parking rack, the second conveyor is transported in the direction orthogonal to the moving path and delivered to the parking rack.

On the other hand, the pallet carrying the delivery vehicle is conveyed in the direction orthogonal to the moving path by the cooperation of the third conveyor of the parking shelf for storing the delivery vehicle and the second conveyor corresponding to the parking shelf. It is delivered to the first conveyor, and is forwarded to the exit port side along the moving path by a plurality of adjacent first conveyors, and the exit vehicle gets out of the pallet and exits from the exit port.

During this period, the other first to third conveyors are not affected by the operations of the first to third conveyors involved in the loading and unloading at all, and can be driven independently of each other. Vehicles can be loaded and unloaded from the parking shelves at the same time in parallel, and a plurality of vehicles can be loaded and unloaded without waiting time, which improves efficiency of loading and unloading.
