Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a multi-story parking system, and more particularly to a multi-story parking system for automobiles in the form of a multi-story warehouse, which is equipped with storage racks and a stacker crane.

BACKGROUND OF THE INVENTION In cities, securing parking is a major social problem that is becoming increasingly serious as the number of automobiles increases. In the case of flat parking, in which cars are parked on vacant land, approximately 10 m of land space is required for each normal passenger car, which is extremely inefficient in land use.

On the other hand, if a flat parking lot is converted into a three-dimensional building with several floors, land use efficiency can be increased by an amount corresponding to the number of floors, but the construction cost of the parking lot building is enormous. Small-scale multilevel parking systems are also used in the form of gondolas that accommodate one car at a time, but they cannot accommodate more than 10 cars due to the height limit of the equipment. difficult.

On the other hand, in highly automated factories, multi-level warehouses that combine storage racks and stacker cranes are in use.

This system is equipped with a movable stacker crane equipped with a telescopic fork for loading cargo that can be raised and lowered, and a shelf-type cargo storage rack is stacked in multiple tiers on one or both sides of the stacker crane's running path to accommodate cargo. Carrying cargo into the space/
Unloading is performed by moving the stacker crane and lifting, lowering, and extending/contracting the cargo loading fork.

If we store cars instead of cargo in this multi-storey warehouse, for example, even if we arrange 10 rows of storage racks on each side of the stacker crane and can accommodate 200 cars, the land area would be only about 3007 Fi, so it would take up a lot of space. Not only can they be used efficiently, but the facility construction costs are much lower than if they were built in a building.

However, when carrying cargo into and out of a multi-story warehouse, generally, the lower surface of the pallet loaded with cargo is supported by forks, and a stacker crane is used to transport the cargo to a predetermined storage space position on the storage rack. Carrying in is carried out by placing the entire pallet on a cargo storage shelf installed in the storage rack, and carrying out is carried out in the reverse order. Therefore, if this method is applied to a car parking system, a special large and heavy pallet is required to place the car on top, so a space is required to store empty pallets, and - Disadvantages such as the need for wasted waiting time for preparing an empty pallet on a fork or storing it in a storage area each time it is carried out were unavoidable.

Purpose of the Invention Therefore, in view of the drawbacks of the prior art, the purpose of the present invention is to use a multi-storey warehouse format, which improves land use efficiency, reduces equipment construction costs, and moreover, eliminates the need to use pallets in the car storage space. By making it possible to mutually transfer cars between the car storage shelf and the car loading fork device on the stacker crane, dedicated pallets can be eliminated, saving empty pallet storage space and wasting time during loading and unloading. To provide a multi-level parking device that eliminates the need for waiting time at all.

Structure of the Invention The structure of the present invention to achieve the above object is a multi-level warehouse type warehouse comprising a storage rack and a stacker crane equipped with a car loading fork device that can access any car storage space on the storage rack. In the multi-story parking device, at the inner end of the car storage shelf provided in the car storage space and at both ends of the car loading fork device,
forming first comb teeth and second comb teeth that can mesh with each other;
The latter can pass up and down in the gap of the former, and the upper surface of any S tooth can support the tire contact surface of the vehicle to be accommodated, thereby increasing the number of parts of the vehicle-loading fork device. After loading the car so that the tires are placed on the comb teeth of No. 2 and transporting it to the front of the designated car storage space using the stacker crane, the car loading fork device is extended onto the car storage shelf in the car storage space and is moved downward. When lowered, the second comb teeth that supported the car tires pass between the first comb teeth provided on the car storage shelf, so the car remains on the first comb teeth of the car storage shelf. The gist of the system is that, while the vehicle is being transferred, the reverse transfer is possible by lifting the vehicle loading fork device from below to above the vehicle storage shelf when transporting the vehicle.

Example Examples will be described below with reference to the drawings.

The multi-story parking device has car storage spaces 11.11...
It consists of a storage rack 10 stacked in multiple stages, and a stacker crane 20 that can move along the storage rack 10 (Fig. 1).
