DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parking lot facility provided with an automobile transporting device and a three-dimensional shelf for storing automobiles provided on a side of a traveling passage of the transporting device.

[0002]

2. Description of the Related Art In a parking lot of this type, there is no need to drive a car on the floor at all. Although it is possible to sufficiently increase the accommodation efficiency, in this type of conventional three-dimensional warehouse type parking lot facility, the car transport device moves the car in a direction in which the traveling direction coincides with the lateral width direction of the car. It was configured to support. Therefore,
When a vehicle is transferred between the vehicle transport device and each of the vehicle support sections, the vehicle is transported by a conveyor in the longitudinal direction (vehicle traveling direction).

Further, a large-sized stacker crane provided with a lifting carriage having a lifting stroke capable of covering the entire height of the three-dimensional shelf has been used as the above-mentioned automobile transport device.

[0004]

In the above-mentioned conventional parking lot equipment, the car transport device and the car support section of the three-dimensional shelf are configured in accordance with the car having the maximum allowable total length. Therefore, the lifting carriage of the stacker crane, which is heavy in weight, has a very large length in the left-right width direction with respect to the traveling direction, so that a large and heavy lifting carriage is required to obtain the required strength. In addition, the length of the conveyor installed on the elevator carriage or on the car support section for transferring vehicles becomes longer, which not only increases the cost, but also increases the time required for transfer, so that loading and unloading takes place. However, there was a disadvantage that the cycle time was longer. Furthermore, since the vehicle is transported in the traveling direction during transfer, if the parking brake of the vehicle is forgotten, or if it is not fully applied, the vehicle may move on the conveyor due to inertia, which poses a great danger. Will accompany.

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, 40 so that the vehicle can pass through the vehicle in a direction perpendicular to the transverse direction of the pair of conveyors 39, 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 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.

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 moved up to the entry target level. 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 are opposed to 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 then presses the wheel FW, 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 obtained. 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 securely clamped and locked by the two 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 car support 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 transport 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.

According to the first aspect of the present invention,
A car transport trolley running along the car support section row,
Since the vehicle is supported and transported in a direction in which the traveling direction coincides with the longitudinal direction of the vehicle, the transport vehicle has a rectangular shape that is long in the traveling direction and short in the right and left width directions. Even if the traveling direction of the car carrier is slightly longer, not only both ends but also the intermediate position can be easily supported by guide rails, etc. The required strength is reduced, and it is possible to easily reduce the size and weight of each of the upper and lower transport carts.

The total length of the conveyor installed on the transport trolley or the automobile support section of the three-dimensional shelf for transporting the automobile is about the same as the length in the width direction of the automobile, and the automobile is transported in the longitudinal direction. The conveyor itself can be shorter than in the case where it has to be loaded, and in this regard, the cost of the transport carriage at each stage can be reduced.

Further, according to the present invention, instead of using a large and heavy stacker crane as in the prior art, only one light and small carrier truck at the loading / unloading operation level is run. The time required for the horizontal movement between the home position and the car support section to be moved in and out can be shortened, and the transfer conveyor is shortened as described above, so that the transfer carriage and the car can be moved. Since the time required for transferring the vehicle to and from the support section is also shortened, the cycle time for loading and unloading can be greatly reduced. 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, according to the present invention, one of the front-wheel traverse conveyor and the rear-wheel traverse conveyor for transferring the vehicle on the front conveyance device is formed to have a wider width than the other, so that the conveyor width is increased. The center of one wheel of a car can be put on the narrow side of the car, and the other wheel can be set within the width of the wide side of the conveyor. Can be supported.

According to the second aspect of the present invention, a pair of traverse conveyors juxtaposed on the carriage of the elevating and lowering device and on each of the car supporting sections of the three-dimensional shelf are also provided in the vehicle transferring device. The front-wheel traverse conveyor and rear-wheel traverse conveyor are arranged side by side, and the front-wheel traverse conveyor and the rear-wheel traverse conveyor have the same width. In this state, the rear wheels may be placed within the range of the conveyor width of the wide rear wheel side-feeding conveyor, so that vehicles of different types having different axle lengths can be surely mounted on the carriage of the lifting / lowering transport device. Each of the three-dimensional shelves can be supported by each of the car support sections.

According to the third aspect of the present invention, in the traverse conveyor for the front wheels and the traverse conveyor for the rear wheels of the vehicle conveying apparatus, the two conveyors are supported on a conveyor having a narrower conveyor width. Locking means for locking the wheels of the vehicle, the wheels supported on the conveyor on the narrower side of the conveyor are locked, so that vehicles of different vehicle types having different axle lengths with respect to the wheels. The other wheel can be reliably supported on the conveyor with the wide side of the conveyor.
