The door protector 20 is provided with a front and rear end of a fence 22 having a length exceeding an installation interval between the front wheel traverse conveyor 19a and the rear wheel traverse conveyor 19b. It is formed by pivotally supporting the link member 23 and the rear link member 24. Further, the fence body 22 is arranged in parallel with the main frame 701, and its protruding and retracting path is configured to overlap with the conveyor rollers 27a and 27b located at the end portions of the front and rear conveyors 19a and 19b. The end conveyor rollers 27a and 27b
Unlike the other conveyor rollers 29 a and 29 b (FIG. 2) which are pivotally mounted on the conveyor frame 28, the roller is independent of the conveyor frame 28 and is supported by the fence 22 of the door protector 20. Accordingly, the end conveyor rollers 27a and 27b move up and down as the door protector 20 moves up and down. FIG. 1 shows the operating position of the door protector 20 by a two-dot chain line. Then, as shown in FIG. 3, the end conveyor rollers 27a and 27b are connected to the front and rear conveyors 19a and 19b.
The position aligned horizontally with the other conveyor roller 29 is the storage position of the door protector 20.

Is transmitted to the end conveyor roller 27a via the gears 43, 44 and 45, and can be driven synchronously with the front / rear conveyor 19. When the door protector 20 fits into the conveyor frame 28, there may be a case where the position of the end conveyor roller 27a is slightly shifted back and forth, and in consideration of this, the gear 44 is compared with the gear 45. The teeth width is large. Also, instead of gears 43, 44 and 45,
It is also possible to use a friction pulley or the like.

As shown in FIG. 9, a front wheel stopper 21 is provided on the front-wheel lateral feed conveyor 19a.
Although the front wheel stopper 21 is shown only on one side in the width direction of the front conveyor 19a in the drawing, in practice, a symmetrical front wheel stopper 21 is provided on the other side of the front conveyor 19a. I have. In the figure, reference numeral 21 denotes a standby state of the front wheel stopper, and reference numeral 21 'denotes an operation state of the front wheel stopper. The present inventors have already disclosed the details of the structure of the front wheel stopper 21 in Japanese Patent Application No. 7-63435, and the description thereof will be omitted. Conveyor roller 29 with shaft attached
Among them, the length of the front wheel stopper 21 is set so that the conveyor roller 29E located at the end portion and the operation trajectory of the front wheel stopper 21 tip portion overlap, and the defense range of the front wheel stopper 21 is expanded as much as possible. In addition, collision between the end conveyor roller 27a and the front wheel stopper 21 is prevented.

The operation and effect obtained from the embodiment having the above configuration are as follows. The end conveyor rollers 27a and 27b of the front-wheel traverse conveyor 19a and the rear-wheel traverse conveyor 19b provided on the lift 7 of the traveling vehicle 6 are provided independently of the conveyor frame 28, and the end conveyor rollers are provided. The end conveyor rollers 27a and 27b are moved together with the door protector 20, since the door protectors 27a and 27b are stored at the front and rear conveyor ends and are supported by a door protector 20 that can move up and down. Then, at the storage position of the door protector 20, the end conveyor rollers 27a and 27b are aligned with the front / rear wheel lateral feed conveyors 19a and 19b to form a smooth conveyor transfer path. That is, the door protector 20 itself
Since it functions as a part of the conveyor at the storage position, the shape and storage position of the door protector are not restricted by the front / rear wheel traverse conveyors 19a and 19b, and the protection range when the door protector operates is expanded. It becomes possible. Further, when the door protector 20 is at the storage position, a smooth transfer path of the conveyor is secured, and a continuous conveyor path having an appropriate installation interval is formed between the traveling carriage 6 and the parking room 3, Delivery of the vehicle can be performed smoothly.

The end conveyor rollers 27a and 27b are
At the storage position of the door protector 20 aligned with the front / rear wheel traverse conveyors 19a, 19b, the end conveyor rollers 27a, 27
Since b is driven by the power transmission means, when the vehicle approaches the end conveyor rollers 27a and 27b, the end conveyor rollers also transmit the driving force in the transfer direction of 27a and 27b to the vehicle. Therefore, even if the tires of the vehicle are punctured, there is no trouble such as the tire being pulled into the gap between the rollers, and the vehicle can be reliably transferred.

Further, the door protector 20 pivotally supports both ends of the fence 22 arranged in the front-rear direction with front and rear link members 23 and 24, and rotates at least one of the front and rear link members 23 and 24. Since the shafts are connected on the left and right, the rotation axis of the front link member 23
By providing the bracket 251 to the 231 and connecting the bracket 251 and the sub-frame 702 provided to the elevating platform 7 by the driving means 26 such as a hydraulic cylinder, the entire door protector 25 can be raised and tilted.

Since the fence 22 of the door protector 20 is installed with a length exceeding the interval between the front and rear traverse conveyors, when the door protector 25 projects, it extends over a wide area before and after the elevator 7. Thus, the fence body 22 can be disposed to prevent release of the doors for getting on and off at various positions of various vehicles. Further, the end conveyor rollers 27a and 27b of the front and rear conveyors 19a and 19b can be simultaneously supported by the fence body 22 and the structure is simple.

In the above-described embodiment, the traveling carriage 6 with a lift has been described as an example. However, the traveling conveyor 19 and the door protector 20 can be used for a traveling carriage without a lift.

[0038]

According to the present invention, the following effects are obtained. The end conveyor rollers of the front and rear wheel traverse conveyors provided on the traveling vehicle are independent of the conveyor frame, and are supported by the door protector. Act as a part. Therefore, the door protector does not become an obstacle on the transfer path of the front / rear wheel traverse conveyor, and the door protector can be arranged at an optimum position. Further, while arranging the door protector so as to have an optimal position and shape to have the widest possible protection range, when the door protector is in the retracted position, the support shaft of the end conveyor roller and As a result, a smooth transfer path for the conveyor can be formed, and the vehicle can be smoothly delivered.

Further, since the end conveyor roller is driven by power transmission means at a storage position of the door protector in which the end conveyor roller is aligned with the front / rear wheel traverse conveyor, the end conveyor roller is driven by power transmission means. When the vehicle approaches the partial conveyor roller, the driving force in the transport direction is also transmitted from the end conveyor roller to the vehicle, so that a uniform transport driving force is always applied to the vehicle, and the vehicle is transported more smoothly. be able to.

Further, the door protector pivotally supports a fence having a length exceeding the installation interval of the front / rear wheel traverse conveyors with the front / rear link members, and Since at least one of the rotating shafts is connected to the left and right, any one of the members constituting the door protector can be used.
By driving the places by the driving means, the entire door protector can be linked. Therefore, the operation control of the door protector is simple and the cost can be reduced.

Further, the fence body has a length exceeding the installation interval of the front / rear wheel traverse conveyor, and is used to release the doors for getting on and off at various positions of vehicles having various shapes. It is possible to form a door protector with a wide protection range to prevent.
