Further, the pair of conveyors 39 and 40 of the car entry / exit work place 9 are configured to move the carriage 8 of the lifting / lowering transport device 6 when the carriage 8 stops at the lower limit position.
It is provided so as to be connected to the upper pair of conveyors 39 and 40.

The vehicle loading / unloading work area 9 has a wheel supporting level of the pair of conveyors 39 and 40 so that the vehicle can be moved in a direction perpendicular to the transverse direction of the pair of conveyors 39 and 40. A step board 41 is provided at substantially the same level as that of FIG. Further, it is preferable that the pair of conveyors 39, 40 of the car entry / exit work area 9 be configured as a belt conveyor or a slat conveyor to facilitate the entry / exit operation of the automobile. Further, power supply and transmission and reception of control signals to and from the motors 16, 27, and 38 on each transport trolley 5 are performed by a power supply rail and a signal transfer rail erected on the side of the traveling path of the transport trolley 5 and a current collector provided on the transport trolley 5. It can be performed using a unit.

The parking lot facility constructed as described above can be used as follows. That is, when entering the car, the car is caused to enter the car entry / exit work area 9 by the self-propelled vehicle from the side of the rear-wheel traverse conveyor 40, and the front wheel is placed substantially at the center of the width of the front-wheel traverse conveyor 39. To stop. At this time, regardless of the vehicle type (the distance between the front and rear axles), the rear wheels are placed on the wide rear wheel traverse conveyor 40. The carriage 8 of the lifting / lowering transport device 6 is stopped at the lower limit position, and a pair of conveyors 39, 4 on the carriage 8 is moved.
0 and a pair of conveyors 39, 4 on the car entry / exit work area 9
In a state in which the vehicle is connected to the vehicle 0, the conveyors 39 and 40 are simultaneously driven in the same direction, and the vehicle in the vehicle entrance / exit work area 9 is laterally transported to a predetermined position on the carriage 8.

After the vehicle has been transferred onto the carriage 8 of the elevating and lowering transport device 6, the carriage 8 is then raised to the level to be stored. Of course, the carriage 8 at the lower limit position
If the lowest level, which is the same as above, is to be stored, the ascending operation of the carriage 8 is unnecessary. On the other hand, the transport vehicle 5 at the entry target level is stopped and waited at the home position HP, the transport vehicle 5 and the carriage 8 stop adjacently at the same level, and the pair of conveyors 12 and 13 on the transport vehicle 5 and the carriage 8 are stopped. In a state where the upper pair of conveyors 39 and 40 are connected, the pair of conveyors 12 and
13 and a pair of conveyors 39 and 40 on the carriage 8 are simultaneously driven in the same direction, so that the vehicle on the carriage 8 is laterally transferred onto the carrier 5.

A pair of conveyors 1 on a carriage 5 for transporting an automobile
If the front wheels 2 and 13 are supported, the pair of front wheel holding bodies 29 and 30 of the front wheel locking means 14 are moved in a direction approaching each other, and the front wheels on the conveyor 12 are held by the front wheel holding bodies 29 and 30 from front and rear. The vehicle is fixed on the carrier 5.

At this time, the driving means 31a, 31b of the front wheel holding body 29 on one side and the driving means 32a, 32b of the front wheel holding body 30 on the other side, which face each other with the wheel FW therebetween, are independent of each other. Since the driving means such as the motor 38 and the screw shaft 35 are provided for each of the holding bodies 29 and 30, the front wheel holding body 29 on the front side located forward and backward with respect to the wheel FW.
And the rear-side front wheel holding body 30 are independently slidably driven. For this reason, when the wheel FW placed on the conveyor 12 is stopped slightly biased to any one of the front and rear sides from the center thereof, the front wheel holding bodies 2
When the driving members 9 and 30 are driven so as to approach the wheel FW, the holding body 29 or 30 on one of the sides is moved to the wheel FW.
, And the wheel FW is pressed first, and then the holding member 30 or 29 on the other side comes into contact with the wheel FW. However, as described above, the holding members 29 and 30 are independently driven. In addition, since both holding bodies 29 and 30 are slidably moved back and forth, if each holding body 29 and 30 comes into contact with and presses the wheel FW, this pressing state is achieved. Can be connected to each of the holding members 29 and 3 by using a well-known detection means such as a pressure sensor.
0 of driving means 31a, 31b, 32a, the motor 38 of 32b is stopped to each other, the front and rear holding member 29, 30 it is possible to stop halfway the slide example conveyor 12 on which is to Even if the loaded wheel FW is slightly deviated back and forth from the center thereof, the wheel FW can be reliably clamped and locked by the both clamping bodies 29 and 30 at the deviated position.

In this state, the carriage 5 is moved forward to a position adjacent to the vehicle support section 4 to be stored. Of course,
If the car support section 4 adjacent to the side opposite to the side where the lifting / lowering conveyance device 6 is located is the entry target section, the front wheel locking means 14 is actuated on the conveyance cart 5 stopped at the home position HP or the conveyance is performed. It is not necessary to run the cart 5.

The transport vehicle 5 is a vehicle supporting section 4 to be stored.
When the pair of conveyors 12 and 13 on the transport vehicle 5 and the pair of conveyors 39 and 40 on the vehicle support section 4 to be stored are connected, the pair of front wheels of the front wheel locking means 14 is stopped. After the holding bodies 29 and 30 are moved away from each other to unlock the front wheels, the pair of conveyors 12 and 13 on the transport vehicle 5 and the pair of conveyors 39 and 40 on the vehicle support section 4 to be stored are simultaneously the same. Drive in the direction,
The vehicle on the transport trolley 5 is fed rightward or leftward and transferred into the vehicle support section 4 to be stored.

The loading operation of the vehicle into the specific vehicle supporting section 4 is completed as described above. By operating the carrier 5 and the lifting / lowering transporting device 6 in the reverse order of the storing operation, the specific vehicle supporting section 4 is operated. It can be easily understood that the vehicle stored in the vehicle 4 can be taken out of the vehicle entrance / exit work place 9. Further, the vehicle carried out onto the pair of conveyors 39 and 40 of the vehicle entrance / exit work place 9 can leave the work place 9 by using the step board 41 to run straight and self-propelled.

In the above embodiment, each car support section 4
As shown in FIG. 7 and FIG. 8, a transport carriage 5 is provided for each stage of the vehicle support section 4, and transports a stacker crane 42 traveling along the travel path 1 between the three-dimensional shelves 2 and 3 as shown in FIGS. It can also be used as a device. The stacker crane 42 has a guide rail 43 on the floor.
Frame 44 and ceiling guide rail 4 guided by
A carriage 48 that moves up and down along an elevating guide column 47 that connects the upper frame 46 guided by the carriage 5, and a pair of conveyors 12, 13 provided on the carriage 4 on the carriage 48. The pair of conveyors 12 and 13 on the carriage 48 are moved to the three-dimensional shelf 2 by running the crane body and moving the carriage 48 up and down.
3, a pair of conveyors 39 of any vehicle support section 4,
40.

When the stacker crane 2 is stopped at the home position HP set at one end of the traveling passage 1, the pair of conveyors 12, 13 on the carriage 48 at the lowermost position are connected to the left and right ends, respectively. Thus, the conveyors 49, 50 for entry and the conveyors 51, 52 for exit are provided side by side. The outer ends of the storage conveyors 49 and 50 become the vehicle storage work place 53, and the storage conveyors 5 are provided.
The outer ends of the reference numerals 1 and 52 form an automobile leaving work place 54.

According to the embodiment using such a stacker crane 42, not only can the single-stage stacker crane 42 be used for each stage of the transport carriage 5 and the elevating and lowering transport device 6, but also the stacker crane 42 can be used. All of the left and right sides of the home position HP except for the lower end can be used for the car support section 4, so that the storage efficiency can be improved, and the car entrance / exit work area is divided into entry and exit. Can help reduce the cycle time of entry and exit.

[0026]

According to the first aspect of the present invention,
This is because the vehicle transporting device (the transporting trolley 5 or the stacker crane 42 in the embodiment) traveling along the vehicle supporting section row supports and transports the vehicle in a direction in which the traveling direction coincides with the longitudinal direction of the vehicle. The vehicle transporting device has a rectangular shape that is long in the traveling direction and short in the right-left width direction. Even if the traveling direction of the vehicle transport device is somewhat longer, not only both ends but also the intermediate position can be easily supported by guide rails etc. The required strength is reduced, and the size and weight can be easily reduced.

Also, 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 width direction of the vehicle, and the vehicle must be transferred and transferred in the longitudinal direction. The conveyor itself can be shorter than in the case where it must be done, and this can also reduce costs. Further, as the transfer conveyor is shortened as described above, the time required for transferring the vehicle between the transfer device and the vehicle support section is also shortened, and the cycle time for loading and unloading can be shortened. In addition, since it is to transport the car to the left and right width direction at the time of the transfer, or have the parking brake has been forgotten over the car, even if it is not fully applied, the car floats on a conveyor by inertia at the time of transfer risk And safety is improved.

Further, of the front wheel traverse conveyor and the rear wheel traverse conveyor for transferring the automobile on the transfer device, the width of the rear wheel traverse conveyor is set to the front wheel traverse conveyor. Because it is formed wider than the width, it is sufficient to place the rear wheel within the range of the conveyor width of the wide rear wheel lateral feed conveyor with the front wheel of the car mounted on the front wheel lateral feed conveyor. Thus, it is possible to reliably support vehicles of different vehicle types having different axle lengths.

According to the second aspect of the present invention, a pair of traversing conveyors arranged side by side at the side of the home position of the vehicle transporting device and at each of the vehicle supporting sections are also provided in parallel with the vehicle transporting device. The front wheel traverse conveyor and rear wheel traverse conveyor, and the front wheel traverse conveyor for the front wheel and rear wheel traverse conveyor of the same width, respectively, so that the front wheels of the vehicle are mounted on the front wheel traverse conveyor. Then, the rear wheels may be placed within the range of the conveyor width of the wide rear wheel lateral feed conveyor, so that vehicles of different vehicle types having different axle lengths can be reliably supported by the respective vehicle support sections. .

According to the third aspect of the present invention, the vehicle wheels supported on the conveyor by the front-wheel transverse conveyor having a narrow conveyor width among the front and rear wheel transverse conveyors provided in the vehicle transport apparatus. Lock means for locking the vehicle, the wheels supported on the front-wheel lateral feed conveyor with a narrower conveyor width are locked, so that the other of the vehicles of each model having a different axle length based on the wheels. Can be reliably supported on the rear-wheel lateral feed conveyor having a wide conveyor width.
