2. Description of the Related Art In general, a planar reciprocating pallet-type mechanical parking lot is generally provided with an entrance / exit opening for entering or exiting a car, a lift device for transporting a vehicle from the entrance / exit opening to each parking floor, and each parking floor. And a parking room for storing the vehicle.

[0003] Explaining the entry operation of a car, a car that has entered the entrance is stopped on a pallet at the entrance, and when all of the occupants have exited and the apparatus is started, the pallet transfer device is used to enter the entrance. From on the lift. The lift carrying the car rises or descends to the parking floor where the car is stored and stops at a predetermined parking floor. Then, the pallet transport device transfers the vehicle onto the traveling carriage on each parking floor. The traveling trolley carrying the car travels to a predetermined parking room, stops there, stores the vehicle in the parking room by the pallet transfer device, and completes entry.

[0004] The retrieval operation is the reverse of the aforementioned retrieval operation, and the vehicle is retrieved from the retrieval port. In the above-mentioned pallet-type mechanical parking lot, spaces for storing pallets are provided in upper and lower tiers in each of the entrance and exit ports, a lift device, a traveling vehicle, and a parking room, and a vehicle is mounted between the devices.

It is a double pallet system.

That is, in the initial state where no car is in the parking device, empty pallets are stored in the lower stages of all the lift devices, traveling vehicles, and parking rooms, and the pallets are in the upper stage only at the entrance. It has been placed. The car that has entered the entrance is placed on the upper pallet, and the pallet is exchanged with the lower empty pallet of the lifting device. That is, the upper pallet mounted on the loading port is transferred to the upper stage of the lifting device, and the empty pallet of the lower loading device is transferred to the lower stage of the loading port. The lift arriving at the parking floor then performs the same pallet exchange with the traveling trolley, and the traveling trolley finally exchanges the same pallet with the parking room. Is stored in the upper part of the parking room.

[0006]

In the case of the double pallet system, a total of two pallets carrying a car and an empty pallet must be transported and transferred, so that the transport device becomes more complicated than in the single pallet system. In addition, since two upper and lower pallet storage spaces must be secured, there is a problem that the dimension in the height direction is higher than that of the single pallet system.

Therefore, it is an object of the double pallet system to use a simple mechanism at a low cost with a simple mechanism, to reduce the required height in the height direction, and to minimize the time required for transfer.
