Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vehicle attitude control device in a multi-story parking lot.

An example of a multi-story parking lot is shown in FIGS. 1 and 2. Namely, reference numeral 1 denotes a building, which has a carry-in/out work space 2 formed in the center, and a plurality of floors on both sides with this carry-in/out work space 2 in between. In other words, in the embodiment, the pillar members 3 are erected at appropriate intervals.
A first floor 5, a second floor 6, a third floor 7, and a fourth floor 8 are formed by the beam members 4 passed between these pillar members 3. A plurality of parking areas (racks) 10 are formed in the horizontal direction 9 on the second to fourth floors 6, 7, and 8.
These parking sections 10 include a pair of support rods 11 in the horizontal direction 9 attached to the beam member 4, and
It is composed of a plurality of idling rollers 12 attached to. The parking section 10 on the first floor 5 is divided by applying white lines on the floor. On the first floor 5 in the loading/unloading work space 2, there is a pallet 13 for mounting on a vehicle.
A lift device 14 is provided to accommodate each floor 6, 7, and 8. This lift device 14
consists of a drive unit 16 disposed in a recess 15 formed in the floor, a pantograph 17 that performs telescopic vertical movement, and a lifting platform 18 attached to the upper end of the pantograph 17. When, a pallet 1 for being placed on a vehicle is placed on it.
3 is constructed so that the upper surface thereof is flush with or approximately flush with the floor. Note that the number of lift devices 14 installed may be either single or multiple. Within the loading/unloading work space 2, trolleys 19 which are guided by rails 20 and can travel in the horizontal direction 9 are provided corresponding to each of the second and higher floors 6, 7, and 8, respectively. According to such a multi-level parking lot, the car 21 is transferred to the pallet 13, and then lifted by the lift device 14 and transferred to the cart 19.
The car 21 can be carried in by passing the pallet 13 from the pallet 13 to the desired parking lot 10, and the car 21 can be carried out by performing the reverse operation.

However, in conventional multi-level parking lots, if the road conditions around the parking lot entrance are poor, the distance from the entrance to the pallet is short, or the driver's driving skills are inexperienced, it is difficult to get into the parking lot within the specified dimensions of the pallet. The problem is that it is difficult to do so.

When it is rotated in the direction of arrow J from the solid line state in FIG. 3, the sensing protrusion 88A is pressed accordingly.

The operation of the above configuration will be explained based on FIG. 15. First, as shown by the solid line in FIG. 15a, before the vehicle 21 enters, both outgoing guide rods 30A and 30B are brought close to each other. This makes it easier for the vehicle 21 to enter, and there is no risk of the wheel 21A accidentally colliding with the outgoing guide rods 30A, 30B.
Also, the piston rod of the second cylinder 35 is contracted, and the tip guide rods 34A, 34B are rotated in the direction of arrow D to spread them out in a V-shape. Furthermore, both the inner guide rods 32A and 32B are kept apart from each other. Further, the rotation of the belt 38 is stopped by the electromagnetic clutch 40, and the frame 36 of each base conveyor 26 to 29 is fixed by holding the L-shaped rod 47 with scissors 46. Next, when the vehicle 21 enters the attitude centering device 23 and stops obliquely to the direction of arrow A as shown by the imaginary line in FIG. Allow free rotation, or spread the tips of the scissors 46 to release the grip of the L-shaped rod 47. Then the first
The piston rod of the cylinder 31 is contracted to move the outgoing guide rods 30A, 30B in the direction of arrow B, and the outgoing guide rods 30A, 30B are pressed against each wheel 21A via the slider 62. Then, each of the belts 38 supporting the pressed wheel 21A rotates separately, and each frame 36 works separately in the direction of arrow A or the opposite direction, and the car 21 moves to the position shown in FIG. 15b. As shown, it is positioned at the center of the track guide device 22 along the direction of arrow A. Next, the electromagnetic clutch 40 is deactivated to stop the rotation of the belt 38, and the piston rod of the fifth cylinder 58 is contracted to connect the presser foot 5 of the lever 55 via the wire rope 56.
7 is pressed against the lower surface of the frame 36 to prevent each frame 36 from moving. At the same time, each tip guide rod 34A, 34B is rotated in the direction of arrow E to be aligned with each inner guide rod 32A, 32B. Next, the rotary solenoid 87 is operated to rotate the rotating shaft 76 and both support plates 78 in the direction of arrow L, and the switch operating rod 81 shown in solid line in FIG.
is caused to protrude outward from the guide roller 67. Next, the piston rod of the second cylinder 35 is extended to move the inner guide rods 32A, 3 as shown by the solid line in FIG. 15b.
Move 2B in the direction of arrow C. Then, the switch operating rod 81 hits the front wheel 21A, the arm 79 is rotated in the direction of arrow J against the second spring 82, and the sensing protrusion 88A of the limit switch 88 is pressed by the striker 89. . Due to this pressure, a signal is output from the limit switch 88, the operation of the second cylinder 35 is stopped, and the distance between the two inner guide rods 32A, 32B is
The width is set to be slightly larger than the width of 1. Then the first
As shown by the phantom lines in Figure 5C, both outgoing guide rods 30
Wheel 21A by moving in the direction of arrow C of A and 30B.
Separate from. Next, when the car 21 is started, it moves in the direction of arrow A guided by both inward guide rods 32A and 32B, and is brought onto the pallet 13 as shown by the solid line in FIG. 15C. Next, after moving the inner guide rods 32A and 32B in the direction of arrow B, the pallet 13 is raised by the drive unit 16 as described at the beginning, and the predetermined drive wheel 21 is stored. Further, when the car 21 moves onto the pallet 13, the operation of the fifth cylinder 58 is stopped,
Separating the presser foot 57 from the lower surface of the frame 36,
Next, hold the L-shaped rod 47 with scissors 46. Then, each frame moves independently along the first guide rail 41, and each base conveyor 26-2
9 is returned and fixed to its original initial position in the direction of arrow A for receiving the vehicle.

When taking out the car 21 in the multi-storey parking lot, the procedure described above may be reversed.

As described above, according to the vehicle attitude control device in a multi-story parking lot of the present invention, even if the road conditions around the parking lot entrance are poor, the distance from the entrance to the pallet is short, or the driving technique is inexperienced. Even if the car is placed in the attitude centering device diagonally to the predetermined approach direction, each base conveyor that supports the wheels is rotatable, so each outgoing guide rod By simply pressing the wheels against the inner surface of each wheel, the vehicle can be easily adjusted to a desired posture. In this state, when the car is started after the tip of each inward guide rod is brought into contact with the outer surface of each front wheel, the car is guided by both inward guide rods and smoothly brought onto the pallet. Furthermore, since the vehicle can enter the vehicle with both of the outgoing guide rods close to each other, the vehicle can easily enter the vehicle, and there is no risk of the wheels accidentally colliding with the outgoing guide rods.
