BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mechanical parking lot using high-speed carriages.

[0002]

2. Description of the Related Art In a mechanical parking lot installed underground, it is necessary to store cars in a limited space with a high density. A parking system in which storage shelves are arranged up to one or two rows on both sides of a high-speed carriage passage has already been implemented. However, a method of arranging storage shelves with three or more rows has not yet been known. Japanese Patent Laid-Open No. 4-62270 discloses a high-density puzzle-type parking system using a puzzle system. The maximum number of vehicles that can be stored in this parking system is about 50. If the number of vehicles that can be stored exceeds this number, the time required for loading and unloading will be longer, and it is better to divide the system.

[0003]

DISCLOSURE OF THE INVENTION The present invention is disclosed in the above-mentioned Japanese Patent Laid-Open No.
-By combining a parking lot system by 62270 (called a puzzle-type parking lot) with a high-speed trolley, the storage density can be increased by arranging three or more rows of storage shelves, and entry / exit time can be shortened. It is an object of the present invention to provide a parking lot that can increase the efficiency of empty pallets by sending them to the elevator with a storage conveyor via the empty pallet lateral feed device used for storage and using them for storage vehicles.

[0004]

[Means for Solving the Problems] A parking lot is composed of a plurality of levels, each level is divided into a plurality of zones of about 30 cars, and the pallet P is front, rear, left and right independently in each zone. The necessary pallet P is moved to the trolley passage side by computer control while moving, and the empty pallet after leaving the car is entered by the elevator 13b with the outgoing conveyor via the empty pallet traverse device 14. The pallet traverse device 14 has a function of transferring a pallet and a function of being able to pull one pallet P by transferring the pallet P to a conveyor-equipped elevator 13a so that it can be used as a warehousing vehicle. Further, a pallet stacking mechanism is added to the empty pallet traverse device 14 so that a plurality of pallets can be pooled.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Prior to explaining the present invention, a puzzle-type parking lot of the previous invention will be described with reference to FIG. In this parking system, the parking section 1 is divided into a matrix as shown in FIG. 1 and includes a plurality of division spaces 2 to which different space numbers are assigned. The number of pallets 3 is determined corresponding to each division space 2 so that at least two of the division spaces 2 are empty spaces. A different pallet number is assigned to each pallet 3, and a space for arranging a plurality of pallets 3 is secured in the entry / exit section 4. Then, when the pallet 3 is arranged, one end side (left side in FIG. 1) of the pallet 3 serves as a storage port and the other end side (right side in the diagram) serves as a storage port.

In the puzzle-type parking lot system of the present invention, a transfer means for transferring the pallet 3, a controller 5 for controlling the transfer means, and a space number where the pallet 3 is located corresponding to the pallet number. , A storage device 6 for storing entry information indicating whether or not the pallet 3 is empty and a vehicle type. When the vehicle is loaded, the control device 5
Determines the number of pallets 3 to be used based on the type of the incoming vehicle, refers to the storage device 6, and controls the transfer means to move the pallets 3 from the entry / exit section 4 to the parking section 1. Further, when the vehicle is to be unloaded, the control device 5 refers to the storage device 6 based on the pallet number on which the vehicle to be unloaded is installed to control the transfer means to move the pallet 3 from the parking part 1 to the entry / exit part 4.
I am trying to transfer it.

After mounting the vehicle on the empty pallet 3, the control device 5 rewrites the entry information corresponding to the pallet number of the empty pallet 3 to "reception" and associates the vehicle number with the pallet number. It is stored in the storage device 6. Then, the transfer means is controlled to store the pallet 3 in the parking section 1, and the space number where the pallet 3 is located is stored in the storage device in association with the pallet number.

On the other hand, in the case of warehousing, when the vehicle number to be evacuated is input, the control device 5 searches the storage device 6 and the pallet number and the pallet number on which the vehicle of the corresponding vehicle number is mounted. By recognizing the corresponding space number, this pallet 3 is moved while moving the other pallets 3 and positioned at the entry / exit section 4.

As described above, since the number of pallets to be used is determined according to the type of vehicle, the entry / exit control is performed, and it is not necessary to provide the rotary table as in the conventional case, the type of parking vehicle is not limited, Moreover, the parking space can be widened.

Although the mechanical parking system is efficient as described above, the number of stored vehicles is about 50 because of the time required for loading and unloading as described above, which is not enough for a large parking lot with more than 100 vehicles. There was room for improvement.
The present invention solves this problem and is described in detail below.
