Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to a carrier equipped with a vehicle transfer device in an elevator-type or elevator-slide-type parking device.

(b) Prior art In conventional early parking systems, devices for transferring cars between a movable carrier and a storage room include a fork type that transfers cars using a fork, and a roller conveyor installed in the carrier and the storage room. A roller conveyor type that is driven and transported by lifting the front or rear braking side wheels of a car and moving them.
There is a wheel-carrying type that rotates and transports the other wheel while keeping it on the ground.

(c) Problems to be solved by the invention In the fork type and roller conveyor type transfer methods, costs are high because a fork or roller conveyor must be installed in each storage chamber, and the wheel holding type is Since only the braking wheel is lifted and the other wheels are kept on the ground, there is no problem when the direction of the wheel matches the direction of transport, but if the wheel does not match due to the way the handle is turned In addition, when the wheels are braked, the vehicle is dragged and transported, which not only makes the transport not smooth, but also damages the vehicle. There were drawbacks such as the need to select wheels.

(d) Means for Solving the Problems In order to improve the above-mentioned drawbacks, the present invention provides a parking system that is movable within the central passageway of the parking equipment headquarters, which has multiple car storage rooms and multiple floors facing each other on both sides. During conveyance, a conveyor having multiple rows of chains at its tips that are engaged with chain guides made of plate-shaped bodies and whose tips are sharply inclined is placed on a car loading platform with a distance greater than the distance between the front and rear wheels of the car. The conveyors are arranged in two rows parallel to each other in the length and width of the vehicle track, and are provided with drive devices that drive each conveyor in the same direction, at the same speed, and in forward and reverse directions, and the vehicle loading platform is extendable and retractable to the carrier body The interlocking mechanism is telescopically equipped on the intermediate body attached to the holder, and the conveyor's transfer direction and the car platform's expansion/contraction direction are opposite to each other, and the conveyor's transfer speed and the car platform's expansion/contraction speed are the same. The feature is that it is equipped with a mechanism.

(e) Effect When transferring a car from outside the carrier into the carrier, we will first explain the effect when there are braked wheels of the car in front of the carrier and unbraked wheels behind it. The two rows of conveyors are each rotated toward the front when viewed from the carrier, and the car mounting platform on the carrier body is extended and moved forward. When the tip of the chain, which is sharply inclined, enters the ground contact part of the wheel, the tire of the wheel is moved forward. The conveyor has elasticity, and the thickness of the tip of the conveyor is sloping and sharp, and it is extremely small compared to the wheels, so it slips between the wheels and gets wedged between the wheels and the ground surface. go. In this case, the tires of the wheels are deformed by the weight of the car and have a contact length of about 10 to 15 cm when viewed from the axle axis direction, so the conveyor Even if the vehicle enters the vehicle, the rest of the ground-contacting parts are in contact with the ground, and the frictional force in the direction of pulling the wheels is applied to the contact part with the conveyor, so the vehicle will not be pushed forward. As the conveyor approaches, the frictional force between the wheels and the chain becomes larger than that at the ground-contact part, and as the car platform advances, the wheels ride onto the conveyor, and as the conveyor moves, the wheels sequentially move onto the conveyor. The vehicle enters the back of the vehicle, but since the conveyor's transport speed and the vehicle loading platform's advancing speed are the same, the unbraked wheels at the rear remain in their original position, and are eventually scooped up by the chain at the tip. Completely accommodated on the conveyor. Therefore,
When the drive of the conveyor is stopped and the car platform is retracted and moved backward, the car is transferred into the carrier. Next, contrary to the above, if there is an unbraked wheel on the front side of the carrier and a braked wheel behind it, the rear wheel remains braked and is on the ground, so the forward movement of the car loading platform will cause the rear wheel to remain braked. The front wheel then rides onto the conveyor, and as the car platform advances, the wheels move deeper into the conveyor, but the conveyor's transfer speed and the car platform's advancing speed are the same, and the directions are opposite. Therefore, the wheels do not rotate and are guided by the conveyor without resistance. Eventually, the braked wheels are scooped up and completely accommodated on the conveyor in the same way as in the previous case, the car platform is retracted and moved back, and the car is transferred into the carrier.

Next, to explain the operation when moving a car inside the carrier out of the carrier, the car mounting platform on the carrier body is extended and entered into the storage chamber, and then the two rows of conveyors are rotated to the transfer side. When the car platform is retracted and moved backward while moving the vehicle, the transfer speed of the conveyor and the backward speed of the car platform are the same and the directions are opposite, so the car maintains its position relative to the storage room. Mama,
The car platform comes off and the car lands.

(F) Embodiment An embodiment of the present invention will be described with reference to the drawings. In FIGS. 1 to 3, 1 is a carrier body, 2 is an intermediate body, and 3 is a car mounting stand. 2 is engaged with the guide rollers 7 of the car mounting stand 3, and rollers 8 provided on both sides of the car mounting stand 3
When the car mounting table 3 is inside the carrier body 1, it is engaged with a track surface 9 provided on the carrier body 1, and is movable only in the left and right directions in the figure. Reference numeral 10 indicates a drive sprocket 12 (the motor 11 and the drive sprocket 12 are shown in FIG. 1) which is driven by a motor 11 provided on the carrier body 1 as shown in FIGS. The chain is stretched around floating sprockets 13 and 14 provided at the front and rear of the carrier body 1, and then the direction is changed by 180° and the chain ends are fixed 15 and 16 to the rear and front of the intermediate body 2, respectively. 11 causes the intermediate body 2 to move and expand and contract in the left and right directions in the figure.

Next, in FIG. 7, 17 is a chain,
One end of the carrier body 1 is fixed 18 on the right side in the drawing, and is stretched over a sprocket 19 rotatably supported on the left side of the intermediate body 2. After that, the direction is changed by 180° and the car mounting table 3 is fixed. Fix the other end towards the right side 2
It's 0. 21 is also a chain, and symmetrically to the above, one end of which is fixed to the left side of the carrier body 1 22
After being stretched over a sprocket 23 rotatably supported on the right side of the intermediate body 2, the other end is fixed 24 on the left side of the car mounting table 3 after changing its direction by 180 degrees. Next, in FIG. 1, a conveyor 25 consisting of two 4-row chains arranged in parallel on the car platform 3 is installed with a length equal to or longer than the distance between the front and rear wheels of the car, and in two rows to match the rut size of the car. It is set up. As shown in FIGS. 8 to 10, this conveyor 25 has a chain guide 26 whose tip is inclined and has a sharp point.
The intermediate part is supported by floating sprockets 27, 2.
7..., the central part of which is driven by a drive shaft 29 driven by a prime mover 28 provided on the vehicle platform 3, and the circumferential speed of the conveyor 25 and the vehicle platform 3 are The expansion and contraction speeds are set to be the same. In addition, the storage chamber on the side to be transferred includes a track surface 30 on which the rollers 8 provided on the vehicle platform 3 contact and roll when the vehicle platform 3 moves forward, and a wheel bearing surface 3 that receives the wheels of the vehicle.
1 is provided.

In addition, the chain guide 26 at the tip of the conveyor 25
In order to reduce the thickness of the tip, no sprocket is provided, and the tip is made up of only a guide plate.Therefore, in consideration of wear, the tip is detachable and can be replaced.

Next, to explain the operation, when the prime mover 11 of the carrier main body 1 is driven to rotate the chain 10 in the direction of the arrow in FIG. Moving.
In this case, the carrier main body 1, the intermediate body 2, and the vehicle platform 3 are connected by chains 17 and 21, and the chain 21 has both ends fixedly attached to the carrier body 1 and the vehicle platform 3, 22, 24, Since the intermediate portion thereof is engaged with the sprocket 23 of the intermediate body 2, the movement of the intermediate body 2 to the right causes the sprocket 23 to rotate clockwise (in the direction of the arrow), thereby disengaging the fixed portion 24 of the chain 21, i.e. By pulling the vehicle platform 3, the guide rollers 7 of the vehicle platform 3 roll along the guide rails 6, and the rollers 8 of the vehicle platform 3 roll on the track surface 30 of the storage chamber to move in the right direction ( arrow direction), and moves from the track surface 30 of the storage chamber to the track surface 9 of the carrier body 1. When pulling out, the motor 11 may be rotated in the opposite direction. The car loading platform 3 extends and the car is placed on the conveyor 2.
5 and the action of transferring the car inside the carrier to the outside of the carrier are as described above.

Note that the conveyor in the above embodiment was an endless belt conveyor with a continuous chain from the tip to the rear end, but since the conveyor in the middle part is only for transporting the drawn wheels, belts, rollers, etc. Other conveyors may also be used. In addition, as in another embodiment shown in FIGS. 12 and 13, the chain conveyor is made into a comb-teeth shape, and the wheel receiving surface of the automobile in the storage chamber on the side to be transferred is made to conflict with the comb-teeth, so that the chain conveyor is shaped like a comb. The conveyor 25 has a comb tooth shape that allows the comb teeth to enter.
If the tip is located below the lower end of the vehicle's wheel, the delivery of the vehicle can be carried out more smoothly than in the embodiment described above, although the cost will be higher.

(G) Effects of the Invention As described above, the present invention uses a chain at the tip of the wheel to scoop up and transfer the wheels, so there is no need to install any equipment in each storage compartment, and the vehicle can be moved easily. It can be easily transported regardless of front wheel drive or rear wheel drive, has a simple structure, and can be manufactured at low cost.
