Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle transfer device of a multilevel parking device for transferring a vehicle between a vehicle carrier such as an elevator device or a carriage and a parking space.

[0002]

2. Description of the Related Art Generally, a mechanical multi-story parking system includes a carriage of an elevator system for vertically transporting a vehicle,
It is formed of a combination of a vehicle carrier such as a carriage for horizontally transporting a vehicle and a large number of parking spaces provided along a moving route of the vehicle carrier. Therefore, it is necessary to alternately move the vehicle between the vehicle carrier and each parking space at the time of loading and unloading, and a vehicle transfer device used for this purpose is known.

In this system, for example, a roller rail for movably supporting a pallet for loading a vehicle is provided for a vehicle carrier and each parking space, and a vehicle is loaded with both rollers while being mounted on the pallet. By moving on the rail, it can be sent from the vehicle carrier side to each parking space side, or pulled out from the parking space side onto the vehicle carrier body.

Such a vehicle transfer device is provided with a slide frame in which a pallet driving feed chain is assembled between roller rails on the vehicle carrier side, and a pallet detent mechanism is incorporated on the roller rails on each parking space side. Has been. The slide frame is movable back and forth, and the whole including the feed chain can move forward to the parking space side. Further, the detent mechanism is adapted to be driven to the release position by advancing the slide frame to the parking space side, and to be returned by retracting the slide frame to the original position.

[0005]

According to such a prior art, when the vehicle is loaded, the drive chain start timing is limited after the slide frame is moved forward, while when the vehicle is loaded, the slide frame is retracted. Since the period is limited after the pallet is pulled out, there is a problem that there is a limit in reducing the time required for loading and unloading the vehicle. That is, unless the slide frame moves forward to the parking space side, the detent mechanism is not released, the pallet cannot be sent into the parking space, and when the slide frame is retracted before the pallet is completely drawn out, the detent mechanism is released. This is because the pallet can no longer be pulled out by returning.

In view of the above-mentioned problems of the prior art, the object of the present invention is to enable the detent mechanism to be driven to the release position by both the slide frame and the pallet, so that the time required for loading and unloading the vehicle can be reduced. An object of the present invention is to provide a vehicle transfer device for a multilevel parking device that can be shortened to the maximum extent.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, the structure of the present invention includes a first roller rail disposed in a parking space and having a pallet detent mechanism, and a first roller rail. Correspondingly provided with a second roller rail to be mounted on the vehicle carrier, a slide frame arranged to be movable back and forth along the second roller rail, and a pallet driving feed chain assembled to the slide frame. The gist of the detent mechanism is that it can be driven to the release position by both a slide frame that moves forward toward the parking space and a pallet that moves on the first and second roller rails.

The detent mechanism has a swing lever that is swingably mounted on the tip of the first roller rail, a locking pin that is driven up and down via the swing lever, and a swing lever that moves upward. And a biasing compression spring, and
It is possible to provide a holder for accommodating the locking pin so as to be vertically movable.

[0009]

According to the structure of the invention, since the feed chain for driving the pallet is assembled to the slide frame, when the slide frame and the feed chain are driven at the same time, the pallet precedes the slide frame and the parking space is moved. However, at this time, the detent mechanism can be driven to the release position by the pallet, so that the pallet moves into the parking space at a high speed that is the moving speed of the slide frame plus the driving speed of the feed chain. Can be sent. The detent mechanism returns when the pallet has passed.

On the other hand, since the detent mechanism can also be driven to the release position by the slide frame, the pallet stored in the parking space can be pulled out by advancing the slide frame, and then the slide frame and When the feed chain and the feed chain are simultaneously driven in the backward direction, the pallet can be pulled out to the vehicle carrier at a high speed that is the moving speed of the slide frame plus the drive speed of the feed chain.

When the detent mechanism is provided with a rocking lever, a locking pin, and a compression spring, the compression spring raises the locking pin by urging the rocking lever upward, and the locking pin is moved to the pallet. , And the rocker lever can lower the locking pin when pushed down by the slide frame or pallet to bring the entire release position.

When the locking pin is stored in the holder, the holder prevents the locking pin from falling down, so that the locking pin can be more strongly engaged with the pallet.

In such a three-dimensional parking apparatus, a vehicle storing operation is performed according to the following procedure. That is, first, the vehicle carrier 20 moves along the parking spaces S2, S2, ... To a position corresponding to the parking space S2 of any empty vehicle, and takes out the empty pallet 30. The vehicle carrier 20 moves to a position corresponding to the carriages 40, 40, and transfers the pallet 30 onto one of the carriages 40. The carriage 40 loads the pallet 30 and moves vertically to the loading / unloading room, loads the vehicle on the pallet 30 and returns to the same parking floor. The vehicle carrier 20 may transfer the vehicle together with the pallet 30 from the carriage 40, move to the original position of the parking space S2, and store the vehicle together with the pallet 30 in the parking space S2.

In the unloading operation, first, the pallet 30 on which the vehicle is placed is taken out from the predetermined parking space S2, and the vehicle is loaded together with the pallet 30 via the vehicle carrier 20 and the carriage 40 in the same manner as the warehousing operation. It is sufficient to carry it out to the delivery room and then return the empty pallet 30 to the parking space S2. However, in the loading / unloading room, when another vehicle is immediately loaded on the pallet 30 from which the vehicle has been dropped, the loading / unloading operation and the loading / unloading operation continue in the loading / unloading room. In addition, the point of this loading / unloading operation is that the pallet 30 is irrespective of whether the vehicle is loaded on the pallet 30 or not.
Can be regarded as an operation of transferring from each parking space S2 to the vehicle carrier 20 and an operation of the opposite.

When the pallet 30 is transferred from the parking space S2 to the vehicle carrier 20, first, the slide frame 11 is moved forward from the vehicle carrier 20 stopped at a predetermined position toward the parking space S2 (FIG. 1). . However, the pallet 30 is mounted on the first roller rails 13, 13 in the parking space S2, and the pallet 30 has a positioning block 34 to which the locking pins 14p, 14p of the detent mechanisms 14, 14 correspond. By engaging 34,
It is assumed to be locked.

As the slide frame 11 moves forward, the pushers 11c and 11c are detented.
Riding on the rollers 14s, 14s of the
By depressing p and 14p, detent device 1
4, 14 can be driven to the release position, at this time, the feed chains 12, 12 on the slide frame 11
One end of the pallet is inserted under the pallet 30. The positioning pins 11p, 11 of the slide frame 11
Among the p ..., the pair on the front side in the traveling direction of the slide frame 11 is to be driven downward by this point.

Next, the feed chains 12, 12 are driven in the direction of pulling out the pallet 30, and the feed chains 12,
The nearest pair of 12 engaging pieces 12f, 12f ... Engage with the engaging blocks 35, 35 at the front end of the pallet 30.
Then, at the same time, when the slide frame 11 is retracted in the direction of returning to the original position on the vehicle carrier 20, the pallet 30 corresponds to the sum of the driving speed of the chains 12 and 12 and the moving speed of the slide frame 11. It can be pulled out of the parking space S2 onto the vehicle carrier 20 at a speed. When the pallet 30 is moving, the pallet 30 pushes down the swing levers 14d and 14d via the rollers 14r and 14r (FIG. 7) and the shafts 14c and 14c.
Since the locking pins 14p and 14p are pushed down via the detent mechanism 14,
The release position can be maintained regardless of the backward movement of the.

The pallet 30 has positioning blocks 34, 34 on the front side in the traveling direction of the intermediate portion of the pallet 30.
However, the positioning pin 11 on the side far from the parking space S2
By colliding with p and 11p, the vehicle carrier 20 is stopped at a predetermined position. However, the feed chains 12, 12
Is assumed to be decelerated as the pallet 30 approaches a predetermined position. Further, the pallet 30 can be locked at a predetermined position by raising the other positioning pins 11p and 11p.

On the other hand, when moving the pallet 30 from the vehicle carrier 20 to the parking space S2, first, the positioning pins 11p and 11p on the slide frame 11 on the side closer to the parking space S2 are lowered to move the slide frame 11 into the parking space S2.
By moving forward, the feed chains 12 and 12 simultaneously move forward to the parking space S2 side. At the same time, when the feed chains 12 and 12 are driven, the engagement pieces 12f and 12f of the feed chains 12 engage so as to push the engagement block 35 on the rear side in the traveling direction of the pallet 30 from behind.
At this time, the slide frame 11 does not precede the pallet 30.

Therefore, the pallet 30 is installed in the roller 1 first.
Riding on 4r, 14r, swing levers 14d, 14d
By pushing down, the locking pins 14p, 14p can be pushed down against the compression springs 14e, 14e, and the detent mechanisms 14, 14 can be driven to the release position. Can be sent to the parking space S2. At this time, the slide frame 11 advances to the parking space S2 side even during the movement of the pallet 30 to increase the moving speed of the pallet 30. Further, the locking pins 14p, 14p are returned via the compression springs 14e, 14e when the passage of the pallet 30 is completed, and prevent the pallet 30 from returning. Further, the slide frame 11 retracts immediately after the movement of the pallet 30 is completed, and completes a series of transfer operations.

The vehicle carrier 20 and the carriage 40,
In the same manner with 40, the pallet 30
Can be reprinted. However, the third roller rails 13, 13 on each carriage 40 are also provided with a detent mechanism (not shown) which is similar to that provided for the first roller rails 13, 13.

In the above description, the transfer operation of the vehicle and the pallet 30 between the vehicle carrier 20 which is a dolly and the parking space S2 has been described.
It is also possible to use the carriage 40 as the vehicle carrier 20. That is, by mounting the slide frame 11 having the feed chains 12, 12 on the carriage 40, the carriage 40 has a parking space S2 formed in multiple stages on both sides of the lifting opening H1.
, S2 ..., The pallet 30 can be moved directly.

[0037]

As described above, according to the present invention, the first roller rail having the detent mechanism in the parking space, the second roller rail mounted on the vehicle carrier, and the feed chain are provided. With a slide frame,
The detent mechanism can be driven to the release position by either the slide frame or the pallet, so that the pallet will not slide out of the parking space even if it precedes the slide frame and reaches the parking space. Even if they are separated from each other, they can be moved through the first and second roller rails without any trouble, so that the operation sequence of the slide frame and the feed chain is not restricted, and therefore the time required for loading and unloading can be maximized. It has an excellent effect that it can be shortened to the limit.
