BACKGROUND OF THE INVENTION In the conventional multi-storey parking lot, one car is located on the elevator passage side of each car storage shelf, and one car is located on the back side (the side farther from the elevator passage). If two cars can be parked in each car storage rack, the land can be effectively used. This is because, with the above-described configuration, four cars can be parked at the same height position in one elevator passage, but if not, four cars can be parked at the same height position. In this case, two lift passages are provided, and car storage shelves in which one car can be parked for each of them are provided at the front and rear at the same height position. This is because it requires extra space. However, if two cars can be parked in each car storage rack, this causes another problem (defect) as described below. That is, when a car parked in the back of the car storage rack (hereinafter, referred to as a car in the back) is desired to be unloaded, if there is a car parked on the side of the elevator platform (hereinafter, referred to as the front car), Since there was only one car loading space on the stand, the car in the foreground was once placed on the lift table and then evacuated, then the car in the back was evacuated, and then the car in the foreground was stored again. The work of returning to the shelf has to be performed, and as a result, there is a problem (deficiency) that the operating efficiency is extremely poor.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on the embodiments shown in the drawings. In this specification, the front means the left side of FIG. 1, the rear means the right side of FIG. 1, and the left means the back side of FIG.
The right side means the same side.

A pair of front and rear rack devices 2 are erected and housed in a building 1 having a rectangular plan shape and a high height, with an elevator passage 12 being opened. The rack device 2
Has a car storage shelf 3 which is provided at predetermined intervals in the height direction and is composed of a drive conveyor that can be driven forward and backward with the transport direction facing the front-rear direction. In the car storage rack 3, two cars C whose longitudinal direction (traveling direction) is directed in the left-right direction can be parked in the front and rear. In this embodiment, the car storage rack 3 is the drive conveyor, but the car storage stand 24 described later is used.
Needless to say, when the vehicle transfer device is installed in the vehicle storage rack 3, the vehicle storage rack 3 may be a simple rack.

A space 15 is provided above the floor 15 of the building 1, and a car C enters the storage space 16 through the front entrance and exit port, and a car entrance and exit space 16 passes through the storage space 16. Car C is set to leave. The floor 15
The central portion in the front-rear direction is stepped down from the passage surface 26 outside (front side) of the loading / unloading port. An opening 17 is formed in the center of the floor 15 for a lift 22 to be described later to pass through. Further, below the floor 15, a pit 18 into which the lift 22 is fitted is formed.

A pair of left and right long guide rails 21 are provided on the left and right sides of the building 1 facing the elevator passage 12, and the elevator 22 is vertically movable on these guide rails 21 by a known elevator. ing.

Two upper and lower revolving tables 23 are provided on the elevating table 22 so as to be capable of normal and reverse horizontal rotation, and a car storage table 23 composed of a drive conveyor which can be driven forward and backward is provided on the revolving tables 23. The car C is placed with its lateral direction facing the transport drive direction of the car storage 24, which is a drive conveyor. When a vehicle transfer device is installed on the lift table 22 corresponding to the vehicle storage table 24, the vehicle storage table 24 need not be a drive conveyor.

[0011]

Operation of the Embodiment Next, the operation of the embodiment will be described. First,
The case of parking will be described. When the parking start signal is issued, the following operation is automatically performed. The elevating table 22 descends so that the upper surface of the lower car storage table 24 is outside the entrance / exit (front side).
The elevator table 22 stops when it becomes flush with the passage surface 26. After that, the lower car storage base 24 horizontally turns 90 degrees, and the longitudinal direction, which has been oriented in the left-right direction until now, is directed in the front-rear direction.
At that time, the turntable 2 and the car storage stand 24 are not attached to the floor 15.
It is designed not to collide with or interfere with. Then, car C
Is run and placed on the lower car storage 24. Then, the turntable 23 horizontally rotates 90 degrees. Further, if there is a car C to be parked, the lift 22 descends so as to sink into the pit 18, and the car C is placed on the upper car storage 24 by the same operation as described above. After that, or without the operation of placing the car C on the upper car storage 24, the lift 22 rises and the upper surface of the car storage rack 3 to be parked and the lower car storage 2 are parked.
Stop at the position where the upper surface of 4 is aligned. Then, the conveyor function of the lower car storage stand 24 and the conveyor function of the car storage shelf 3 are operated in synchronization, and the car C is parked on the car storage shelf 3. At that time, when there is a car C on the side of the elevator passage 12 of the car storage shelf 3, the car C in front of it goes to the back, the car C just parked is located in front, and the car storage shelf 3 is empty. If it is, the car C just parked is located in front. When the car C is also mounted on the upper car storage 24, the upper car C is parked on the predetermined car storage rack 3 by the same operation as described above. Next, the delivery will be described. It can be immediately understood that the car C in front (the car C on the side of the elevator passage 12) is unloaded by the same operation as described above, and therefore the description thereof is omitted. The car C in the back (the car C farther from the lift passage 12) is unloaded as follows. First, when the front car C is temporarily placed in the upper car storage 24, the elevator 2
2 rises. After that, the car C in the back on the car storage stand 24 on the lower side
Will be posted. Then, after the elevator 22 descends, the front vehicle C temporarily placed on the upper vehicle storage 24 is returned to the vehicle storage shelf 3, and then the vehicle C at the back is unloaded. The transfer of the car C between the car storage stand 24 and the car storage rack 3 is as described above. If the lift table 22 passes through the position of the vehicle C in front of which the shelves need to be replaced while the lift table 22 is descending, the lift table 22 is temporarily stopped at that position to store the upper car. The vehicle C is placed on the stand 24, and then the elevator 22 stops halfway again at the position of a predetermined empty car storage shelf 3 on the lower side, whereupon the car C on the upper car storage table 24 is placed on the car storage shelf 3 concerned.
Park at.

In order to smoothly move the car C between the car storage rack 24 and the car storage rack 3, the car storage rack 24 should be moved back and forth in a state where the longitudinal direction is in the left-right direction. It is provided on the turning table 23 and is stored in the car storage 24.
May be moved back and forth to fill the gap between the car storage stand 24 and the car storage rack 3 within a possible range.

[0013]

The present invention has the following effects due to the above-mentioned configuration. Since the elevator is equipped with two upper and lower car storage racks, two cars can be parked in each car rack, and when you want to leave the car in the back of the car rack, When the car is parked, first place the front car in the upper car storage,
It is possible to put the back car on the lower car storage stand, then return the temporarily placed front car to the car storage rack, and then take out the back car, resulting in good operating efficiency.
