2. Description of the Related Art In a multi-storey parking lot, there are two systems, a pallet system in which a pallet is used to transport and store a vehicle and a palletless system in which a vehicle is directly transported without a pallet. In the case of the pallet method, it is necessary to collect an empty pallet (hereinafter referred to as an empty pallet) on which no automobile is loaded from the loading / unloading compartment and supply it to the loading / unloading compartment.

A conventional empty pallet processing method in the pallet method is to stock some empty pallets in a loading / unloading room or elevator and to dispense them at the same time as the transfer of the vehicle. Is configured to go to the storage shelf when the pallets are exhausted, and for warehousing, it is returned to the storage shelf when the pallets are accumulated.

[0004]

In the above-mentioned conventional example, since it takes a long time to process an empty pallet, there is a drawback that the loading and unloading time becomes long and the loading and unloading cycle time becomes long as compared with the palletless system which does not use a pallet. It was In a multi-storey car park, the number of vehicles accommodated is determined from the entry / exit cycle time. For example, the maximum number of vehicles that can be delivered in 1 hour and 30 minutes is the maximum number of vehicles that can be accommodated. There is a problem that it cannot be realized.

In view of such circumstances, it is an object of the present invention to provide an empty pallet processing apparatus capable of realizing a large-capacity parking lot by shortening the loading / unloading cycle time.

[0006]

In the empty pallet processing apparatus of the present invention, storage layers for storing automobiles are provided in upper and lower multi-layer floors,
In a multi-storey parking lot in which a loading / unloading room and each storage layer are connected by an elevator for transporting an automobile, the elevator for elevator has a two-stage structure with an upper frame and a lower frame, and each stage has an upper side. A pallet transfer device and a lower pallet transfer device are installed, and the loading / unloading room is composed of a loading / unloading area adjacent to the elevator for lifting and lowering and a pallet processing area adjacent to the elevator side opposite to the loading / unloading area. Installs an upper pallet carrier and a lower pallet carrier in upper and lower two stages and at a vertical interval equal to the vertical interval of the upper and lower pallet carrier of the elevator, and the pallet processing area has a pallet on the upper surface. Install an elevator lifter with a transfer device, and use the lift lifter to move the pallet transfer device on the upper surface to the upper pallet in the loading / unloading area. Characterized by being configured to lift between the feeder raised position of the same height as and lower pallets lowered position of the transport apparatus and the same height. Incidentally, the elevator for raising and lowering referred to in the present specification, the elevator for warehousing,
It includes an elevator for warehousing and an elevator for both loading and unloading. The loading / unloading room includes a loading / unloading room, a loading / unloading room, and a loading / unloading room.

[0007]

According to the present invention, when the elevator for raising and lowering is horizontally placed in the loading / unloading compartment, the upper and lower pallet transporting devices on the elevator side and the upper and lower pallet transporting device on the loading and unloading chamber side are at the same level. The transport device is driven to transfer an actual vehicle pallet carrying an automobile between the elevator and the loading / unloading area, and at the same time, an empty pallet is transferred between the lifting lifter in the pallet processing area and the loading / unloading area. Further, at the same time, both lower pallet transfer devices can be driven to transfer empty pallets between the elevator and the boarding / alighting area. In this case, since the empty pallets can be transferred at the same time as the transfer of the actual vehicle pallets and no extra time is required for processing the empty pallets, the loading / unloading cycle time can be shortened as compared with the conventional case. Therefore, a large-capacity parking lot can be realized.
