[Detailed description of the invention] Industrial applications The present invention relates to a multi-story parking lot.

2. Description of the Related Art Conventionally, a multi-story parking lot in which cars are entered and exited from each parking floor via pallets is disclosed, for example, in Japanese Patent Publication No. 58-20354. This system is equipped with a lift device that can be moved up and down across each parking floor between the loading/unloading space in the center, and a lift device that can be moved freely along the parking spaces on both sides to the loading/unloading space on each parking floor. It was equipped with a delivery trolley for delivering cars and pallets to and from the station.

Problem to be Solved by the Invention However, according to the above configuration, when several cars are parked in succession, the first car is placed on a pallet at the entry/exit floor, and the lift device and the delivery cart are used to park the first car at a predetermined location on a predetermined floor. After loading into the parking space, the empty pallet is transported from the empty parking space to the loading/unloading floor using these delivery devices and lift devices, and then the next car is placed on the narrowed pallet and the process is repeated, which reduces waiting time. was a long one. Further, even when a car is to be taken out of the garage in succession, the waiting time is long because the empty pallet must be returned to its original parking space before the next unloading operation begins.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and provide a multi-story parking lot that can reduce the waiting time even when parking or leaving the parking lot in succession, and improve the efficiency of loading and unloading operations.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a central space that includes:
A lifting platform for an automobile elevator system is installed that allows cars to be loaded on pallets and can be raised and lowered freely across each parking floor. Sub warehousing tables are provided on both sides of the main warehousing table, and sub warehousing tables are provided on both sides of the main warehousing table. A main loading/unloading device is provided for transferring on-vehicle pallets from the main loading/unloading table to the main loading/unloading table, a sub-loading/JI device is provided for transferring the vehicle-mounted pallets from the sub-loading table to the main loading/unloading table, and the on-vehicle pallets are transferred from the main loading/unloading table to the sub-loading table. A sub-delivery device for transporting empty pallets is provided, and an empty pallet conveying device is provided for transporting empty pallets from the sub-delivery table to the sub-delivery table.

Effect In the above configuration, if there are cars that enter the warehouse in succession, pallets are kept waiting on the main warehousing table and the sub warehousing table, and the incoming cars are placed on the pallets of each warehousing table and stopped, allowing customers to exit the vehicle. let Then, the car is transferred from the main warehousing table to the elevator platform by the main warehousing/exiting device, and the car is parked on the parking floor.
While carrying out an empty pallet or on-vehicle pallet, the sub-warehousing device transfers the on-vehicle table from the sub-warehousing table to the main warehousing table. Performs warehousing work for cars on the main warehousing table. Note that the above-mentioned work of carrying out empty pallets or vehicle-mounted pallets to the main unloading table can be omitted by the number of warehousing tables, and the warehousing work can be performed continuously. In this case, empty pallets may be carried out when there is no inventory. Among the pallets carried out, the vehicle-mounted pallet is made into an empty pallet by starting the car from the main unloading table, and this ejected pallet is transferred to the sub unloading table by the sub unloading device. Then, the empty pallet is transferred to the sub-warehousing table by the empty pallet conveying device, and further sent to the main warehousing table where it is kept waiting.

In the case of continuous unloading, the lift is carried out from a designated parking floor to the loading/unloading floor using the lift platform and transferred to the main loading/unloading table. The bonds received on the floor and the next on-vehicle pallet are carried out to the loading/unloading floor. During these operations, the vehicle is started from the vehicle table on the main delivery table, and the empty pallet is transferred to the sub-delivery table by the sub-delivery device. Thereafter, the empty pallet is transferred from the sub-delivery table to the sub-receipt table by the empty pallet conveying device. In addition, the work of transporting empty pallets from the above main storage table or vehicle-mounted pallets to the parking floor,
It is possible to omit the number of vehicles corresponding to the number of unloading tables and perform only the unloading operation continuously, and according to this method, the unloading time can also be significantly shortened. In this case, empty pallets may be brought in when there is no unloading work.
