Further, the power supply and the control signal transmission / reception to / from the motors 16, 27, 38 on each carrier 5 are performed by the power supply rail and the signal transfer rail and the carrier 5 installed on the side of the traveling route of the carrier 5.
It can be performed by using a current collecting unit provided on the side.

The parking lot facility configured as described above can be used as follows. That is, when loading a vehicle, the vehicle is automatically driven into the vehicle loading and unloading work place 9 from the side of the rear wheel transverse conveyor 40, and the front wheel is placed at a substantially central position of the width of the front wheel transverse conveyor 39. Stop. At this time, the rear wheels are placed on the wide rear-wheel transverse conveyor 40 regardless of the vehicle type (the distance between the front and rear axles). The carriage 8 of the lifting / conveying device 6 is stopped at the lower limit position, and the pair of conveyors 39, 40 on the carriage 8 and the pair of conveyors 39, 40 on the vehicle loading / unloading work place 9 are connected to each other. 39 and 40 are simultaneously driven in the same direction to laterally transfer the vehicle in the vehicle loading / unloading workshop 9 to a predetermined position on the carriage 8.

After the vehicle is transferred onto the carriage 8 of the lifting / conveying device 6, the carriage 8 is then moved up to the target level for storage. Of course, if the lowest level that is the same as the carriage 8 at the lower limit position is the storage target, the raising operation of the carriage 8 is not necessary. On the other hand, the carriage 5 at the receiving target level is stopped and waited at the home position HP, and the carriage 5 and the carriage 8 are adjacently stopped at the same level, and the pair of conveyors 12 and 13 and the carriage 8 on the carriage 5 are stopped. With the pair of upper conveyors 39, 40 connected, the pair of conveyors 12, 13 on the carrier 5 and the pair of conveyors 39, 40 on the carriage 8 are simultaneously driven in the same direction to drive the carriage 8. The upper car is transferred laterally onto the carrier 5.

If the automobile is supported by the pair of conveyors 12 and 13 on the carrier truck 5, the pair of front wheel holding bodies 29 and 30 of the front wheel locking means 14 are provided.
The two front wheel clamps 29, 30
The front wheel on the conveyor 12 is clamped from the front and the rear, and the automobile is fixed to the carrier truck 5.

At this time, the front wheel holding body 29 on one side opposite to the front wheel FW is sandwiched.
Drive means 31a, 31b and drive means 3 for the front wheel holding body 30 on the other side
2a and 32b are independent of each other, that is, each holding body 2
Since the driving means such as the motor 38 and the screw shaft 35 are provided for each 9,30, the front wheel holding body 29 on the front side and the front wheel holding body 30 on the rear side, which are located in front of and behind the front wheel FW, are independent of each other. Slide drive. This is because the conveyor 12
When the front wheel FW placed on the top is slightly biased toward the front or rear of the center part of the front wheel FW, both front wheel clamps 29, 3
When the 0s are driven so as to approach each other to the front wheel FW, either one of the holding bodies 29 or 30 comes into contact with the front wheel FW first and presses the front wheel FW, and then the other side holding body 30.
Or, 29 comes into contact with the front wheel FW, but as described above, both holding bodies 29 and 30 are driven independently, and both holding bodies 2
Since 9,30 are designed to move back and forth in a sliding manner, if the holding bodies 29,30 come into contact with the front wheels FW and press them, this pressing state is detected, for example, by a pressure sensor. By stopping the motors 38 of the driving means 31a, 31b, 32a, 32b of the sandwiching bodies 29, 30 individually by using a well-known detecting means, and stopping the front and rear sandwiching bodies 29, 30 in the middle of the slide. Therefore, for example, even if the front wheel FW placed on the conveyor 12 is slightly deviated to the front and rear from the center part thereof, the front wheel FW can be clamped at both sides at the deviated position.
It can be securely clamped and locked with 9,30. In such a state, the transport vehicle 5 is caused to travel forward to a position adjacent to the vehicle support section 4 to be stored. Of course, home position HP
If the vehicle support section 4 adjacent to the side where the lifting / lowering transfer apparatus 6 is present is the storage target section with respect to the transport vehicle 5 stopped at, the front wheel locking means 14 is operated or the transport vehicle 5 is moved. No need to drive.

The transport vehicle 5 stops adjacent to the vehicle support section 4 of the receiving target, and the pair of conveyors 12, 13 on the transport vehicle 5 and the pair of conveyors 39, 40 on the vehicle support section 4 of the receiving target are connected. Then, the pair of front wheel holding members of the front wheel locking means 14
After moving 29, 30 away from each other and unlocking the front wheels, the pair of conveyors 12, 13 on the carrier 5 and the pair of conveyors 39, 40 on the vehicle supporting section 4 to be stored are simultaneously moved in the same direction. The vehicle is driven, and the vehicle on the carrier vehicle 5 is fed rightward or leftward to be transferred into the vehicle supporting section 4 to be stored.

With the above, the operation for storing the vehicle in the specific vehicle support section 4 is completed. However, by operating the transport vehicle 5 and the lifting / lowering transfer device 6 in the procedure reverse to the operation for storing the vehicle, the vehicle is placed in the specific vehicle support section 4. It can be easily understood that the stored car can be put out to the car loading / unloading work place 9. Further, the car carried out on the pair of conveyors 39, 40 of the car warehousing / working space 9 can be driven straight ahead using the walk board 41 to leave the work space 9.

In the above-described embodiment, the carriage 5 is provided for each stage of the vehicle support section 4 as the vehicle carrier for each vehicle support section 4. However, as shown in FIG. 7 and FIG.
The stacker crane 42 traveling on the traveling passage 1 between the two and three can also be used as a transfer device. The stacker crane 42 includes a carriage 48 that moves up and down along a lifting guide column 47 that connects a lower frame 44 guided by the floor guide rails 43 and an upper frame 46 guided by the ceiling side guide rails 45. Thing, the relevant carriage
A pair of conveyors 12 and 13 provided on the transport carriage 5 on the 48.
Etc. are provided, and a pair of conveyors 12, 13 on the carriage 48 are connected to a pair of conveyors 39, 40 of an arbitrary vehicle support section 4 in the three-dimensional shelves 2, 3 by traveling of the crane main body and raising and lowering of the carriage 48. It can be done.

In addition, the home position HP set at one end of the traveling passage 1
When the stacker crane 42 is stopped, the conveyors 49, 50 and the conveyors 51, 52 for loading and unloading are connected to the left and right ends of the pair of conveyors 12, 13 on the carriage 48 at the lower limit position, respectively. Is attached. And the outer ends of the conveyors 49, 50 for warehousing become the car warehousing workshop 53,
The outer ends of the shipping conveyors 51, 52 serve as a vehicle shipping workshop 54.

According to the embodiment using such a stacker crane 42, not only the stacker crane 42 and the lifting and lowering carrier device 6 of each stage can be used by one stacker crane 42, but also the home position of the stacker crane 42 can be used. The left and right sides of the HP can be used for the vehicle support section 4 except for the lower end, which can improve the storage efficiency and can separate the vehicle loading / unloading work area for loading and unloading. Useful for shortening the entry / exit cycle time.

(Operation and Effect of the Invention) According to the parking lot facility of the present invention that can be implemented as described above,
This is because the vehicle transporting device that travels along the vehicle support section row (the vehicle carrier 5 and the stacker crane 42 in the embodiment) supports and transports the vehicle in a direction in which the traveling direction and the vehicle longitudinal direction match. The automobile carrier has a rectangular shape that is long in the traveling direction and short in the right-left width direction orthogonal to the traveling direction. Even if the traveling direction of the automobile carrier is somewhat long, not only both ends but also the intermediate position can be easily supported by the guide rails, etc., so that the left-right width direction becomes shorter than that of the opposite case. The required strength is low and it is easy to reduce the size and weight.

In addition, the total length of the conveyor installed on the transfer device or the vehicle support section for transferring the vehicle is about the length in the left-right width direction of the vehicle, and the vehicle must be transferred in the longitudinal direction. Compared with the above, the conveyor itself needs to be short, and cost reduction can be achieved also in this respect. Further, as the transfer conveyor is shortened as described above, the time required for transferring the vehicle between the transfer device and the vehicle supporting section is also reduced, and the cycle time of loading and unloading can be shortened. Also, since the vehicle is moved in the left-right width direction during transfer, even if the parking brake of the vehicle is forgotten or not completely applied, the vehicle may move on the conveyor due to the inertia during transfer. Less and improved safety.

Further, according to the present invention, since the front-wheel transverse feed conveyor is provided with the locking means for preventing the movement of the wheels, the vehicle is unexpectedly unintentionally caused by the inertia at the time of starting, stopping, accelerating or decelerating during the traveling drive of the transfer device. It is possible to travel safely without moving to the vehicle, and to travel at high speed, so that it is possible to shorten the cycle time of loading and unloading of a vehicle.

In particular, according to the present invention, the locking means is composed of a pair of slide type wheel gripping members which independently drive the wheels on the conveyor so as to approach each other from the front and rear of the wheels so that they are mounted on the conveyor. Even if the wheel is biased slightly forward and backward from the width center part, each holding body can be independently slid to the biased position, and the wheel can be pinched and locked at the biased position. The advantage is that the wheels do not interfere with their locking even if they are not located exactly in the width center of the conveyor.
