Description

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 carrier and a three-dimensional shelf for storing an automobile which is erected on the side of a traveling path of the carrier.

[0002]

2. Description of the Related Art In this type of parking facility, it is not necessary to drive a vehicle on the floor surface at all. Although it is possible to sufficiently enhance the housing efficiency, in the conventional multi-storey type parking lot facility of this type, the vehicle carrier is designed to move the vehicle in a direction in which the running direction of the vehicle and the left-right width direction of the vehicle match. It was configured to support. Therefore,
When the vehicle is transferred between the vehicle carrier and each vehicle supporting section, the vehicle is transferred by a conveyor in the longitudinal direction (vehicle traveling direction).

Further, a large stacker crane provided with a lifting carriage having a lifting stroke capable of covering the entire height of a three-dimensional shelf has been used as the vehicle carrier.

[0004]

In the conventional parking lot facility as described above, since the vehicle carrier and the vehicle supporting section of the three-dimensional shelf are constructed in accordance with the vehicle having the maximum allowable length, the vehicle is originally large in size.

In addition, the total length of the conveyor installed on the elevator carriage or the vehicle support section for transferring the vehicle becomes long, which not only increases the cost, but also lengthens the time required for transfer, which results in the loading and unloading. There was a drawback that the cycle time of was long. Furthermore, since the vehicle is transferred in the traveling direction during transfer, the vehicle may inertially float on the conveyor if the parking brake of the vehicle is forgotten to be applied or is not completely applied. Will be accompanied.

[0005]

With 0 connected, the conveyors 39 and 40 are simultaneously driven in the same direction to laterally transfer the vehicle in the vehicle loading / unloading work place 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 storage target level. Of course, the carriage 8 at the lower limit position
If the same lowest level as the above is the target of warehousing, the raising operation of the carriage 8 is not necessary. On the other hand, the carriage 5 at the storage 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 and 40 connected, the pair of conveyors 12 and 12,
13 and a pair of conveyors 39, 40 on the carriage 8 are simultaneously driven in the same direction to laterally transfer the vehicle on the carriage 8 onto the carrier 5.

A pair of conveyors 1 on an automobile carrier 5
If the front wheels 2 and 13 are supported, the pair of front wheel holding bodies 29, 30 of the front wheel locking means 14 are moved toward each other, and the front wheels on the conveyor 12 are held between the front and rear by the front wheel holding bodies 29, 30. The automobile is fixed on the carriage 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 in between, are independent of each other, that is, Since each holding body 29, 30 is provided with driving means such as a motor 38 and a screw shaft 35, the front wheel holding body 29 on the front side, which is positioned in front of and behind the wheel FW, is located.
The front wheel holding body 30 on the rear side and the rear wheel holding body 30 on the rear side are independently driven to slide. For this reason, when the wheels FW placed on the conveyor 12 are slightly biased to the front or rear side from the central portion of the wheels FW and stopped, both front wheel holding bodies 2 are held.
When 9 and 30 are driven so as to approach each other to the wheel FW, the holding body 29 or 30 on either side is moved to the wheel FW.
Firstly, the wheel FW is abutted first to press the wheel FW, and then the other holding body 30 or 29 comes into contact with the wheel FW. However, as described above, both the holding bodies 29 and 30 are independently driven. In addition, since both holding bodies 29, 30 are slidably moved back and forth, if the respective holding bodies 29, 30 come into contact with and push the wheel FW, the pressed state By using a well-known detection means such as a pressure-sensitive sensor,
It is possible to individually stop the motors 38 of the driving means 31a, 31b, 32a, 32b of 0 so as to stop the front and rear clamps 29, 30 in the middle of the slide, and therefore, to put them on the conveyor 12, for example. Even if the obtained wheel FW is slightly deviated to the front and rear from the center portion thereof, the wheel FW can be reliably 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 vehicle support section 4 adjacent to the side opposite to the side on which the elevating / conveying apparatus 6 is located is the storage target section with respect to the transport carriage 5 stopped at the home position HP, the front wheel lock means 14 is operated or the transport is performed. It is not necessary to drive the dolly 5.

Car carrier 5 is a vehicle support section 4 in which the carriage 5 is to be stored.
If 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 to each other, the pair of front wheels of the front wheel locking means 14 are stopped. After the holding bodies 29, 30 are moved away from each other and the front wheels are unlocked, the pair of conveyors 12, 13 on the carrier 5 and the pair of conveyors 39, 40 on the vehicle support section 4 to be stored are the same at the same time. Drive in the direction,
The vehicle on the carrier vehicle 5 is fed rightward or leftward and transferred into the vehicle support section 4 to be stored.

With the above, the operation of storing the vehicle in the specific vehicle supporting section 4 is completed. By operating the carrier 5 and the elevating / conveying device 6 in the reverse order of this storing operation, the specific vehicle supporting section 4 is operated. It will be easily understood that the vehicle housed in the vehicle 4 can be unloaded to the vehicle loading / unloading workshop 9. Further, the car carried out on the pair of conveyors 39, 40 of the car warehousing / working place 9 can be left as it is by using the walk board 41 to drive straight ahead as it is.

According to the invention of claim 1,
A car carrier that runs along the car support row
Since the vehicle is supported and transported in a direction in which the traveling direction and the longitudinal direction of the vehicle match, the transport vehicle has a rectangular shape that is long in the traveling direction and short in the left-right width direction orthogonal thereto. Even if the traveling direction of the car carrier is somewhat long, it is possible to easily support not only both ends but also the intermediate position with guide rails, etc., so that the width direction becomes shorter than that of the opposite case. The required strength is reduced, and it is possible to easily reduce the size and weight of each of the upper and lower carriages.

Further, the total length of the conveyors installed on the carrier truck or on the vehicle support section of the three-dimensional shelf for vehicle transfer is about the length in the left-right width direction of the vehicle, and the vehicle is transferred in the longitudinal direction. Compared with the case where the conveyors have to be mounted, the conveyor itself can be short, and in this respect as well, the cost of the carrier trucks at each stage can be reduced.

Further, according to the present invention, since a large-sized and heavy-weight stacker crane as in the prior art is not used, but only one lightweight and small-sized carrier truck which is at the loading / unloading work level is run. It is possible to shorten the time required for horizontal movement between the home position and the vehicle supporting section for loading and unloading work, and further, since the transfer conveyor is shortened as described above, the above-mentioned carriage on the vehicle and the vehicle. Since the time required for transferring vehicles to and from the support section is also shortened, the cycle time for loading and unloading can be greatly 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.

According to the second aspect of the present invention, the conveyor width of one of the front-wheel transverse feed conveyor and the rear-wheel transverse feed conveyor for transferring the automobile on the conveyor is formed wider than the other. As a result, it is possible to reliably support automobiles of various vehicle types from large vehicles to small vehicles having different axle lengths.

According to the third aspect of the present invention, the width of one of the two conveyors is formed wider than the other, so that one of the two conveyors is supported by one of the conveyors. Since the locking means for locking the wheels is provided, the vehicle can travel safely without accidental movement due to inertia during start-up or stop during traveling drive of the transfer device or during acceleration or deceleration, and Since it is possible to drive at high speed, it is possible to shorten the cycle time for loading and unloading cars.

Further, according to the invention of claim 4, one of the two conveyors is formed to have a wider width than the other, and the locking means is provided on the conveyor having a narrower width. By locking the wheel supported on the conveyor with the narrower width, the other wheel of each type of vehicle with different inter-axle lengths can be secured on the conveyor with the wider conveyor by locking the wheel. Can be supported by.

Further, according to the invention of claim 5, the lock means is composed of a pair of slide type wheel holding bodies which sandwiches the wheels on the conveyor and slides independently from each other in the approaching and separating directions from the front and rear thereof. Therefore, even if the wheels placed on the conveyor are slightly biased forward and backward from the center of the width, each gripping body independently slides to the biased position to grip the wheels at the biased position. Since it can be locked, there is an advantage that it does not hinder the locking even if the wheels are not accurately located in the center of the width of the conveyor.
