Abstract

PURPOSE:To provide a stopper device for car delivery dolly, whose structure is sturdy and comparatively simple, which has a sufficient strength for bearing the load of a car, and which ensures that the maintenance and inspection works are performed easily. CONSTITUTION:A rotary shaft 64 is borne by a frame vertically, and the base end of an arm 62 is pivoted on this rotary shaft 64 with possibility of swinging up and down. A stopper roller 61 is extended at a right angle from the tip of the arm 62. The tip of arm 62 is lifted by a spring 68, and at normal times, the stopper roller 61 is positioned over a conveyor belt 2 so as to allow free revolution. When a wheel W of a car has pushed the stopper roller 61 down, the spring 68 elongates, and the arm 62 contacts a supporting bolt 69 on the frame 1, which thus bears the load. The rotary shaft 64 is rotated approx. 90 deg. in the regular and reverse directions by hydraulic mechanisms 66, 67, and the stopper roller 61 is revolved in reversals between the operating position and retracted position.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mounts an automobile on a conveyor belt of a vehicle for delivering vehicles, stops the vehicle at a predetermined position to operate the conveyor belt, and sends out an upper automobile to move it to a parking stand. The present invention relates to a parking device having a replacement function, and more particularly to a stopper device for fixing an automobile on a truck for vehicle allocation.

[0002]

2. Description of the Related Art An automobile is placed on a truck for delivering a vehicle, and the vehicle is conveyed to a parking lot at a predetermined position, where a conveyor belt is operated,
There is known a parking device that sends out an upper car and transfers it to a conveyor belt of a parking stand. A movable stopper is provided on the truck for allocating vehicles in such a parking device in order to prevent movement of the automobile during transportation. The movable stopper does not hinder the progress of the automobile when the automobile is placed on the truck for dispatching, but restrains the automobile after reaching a predetermined stop position on the truck for dispatching. However, since the conventional ones are generally movable, the structure is complicated and expensive, and there is a problem in that sufficient strength for supporting the load of the automobile cannot be obtained and they are easily broken.

[0003]

SUMMARY OF THE INVENTION Therefore, according to the present invention, the structure of the vehicle is relatively simple, the structure is robust, the structure is strong enough to support the load of the vehicle, and the maintenance work is easy. It is an object to provide a stopper device for a truck.

[0004]

According to the present invention, in order to solve the above-mentioned problems, a rotary shaft 64 is vertically supported by a frame 1 adjacent to the conveyor belt 2 of a truck 30 for vehicle distribution. A base end side of the arm 62 is pivotally attached to the arm 62 so as to be vertically swingable, and a base end side of the stopper roller 61 is supported on the tip end side of the arm 62 so as to extend in a direction perpendicular to the arm 62. The tip end side of the arm 62 is pulled up and held by the spring 68, and the stopper roller 61 is normally arranged above the upper surface of the conveyor belt 2, and when the vehicle wheel W pushes down the stopper roller 61, the arm 62 moves to the frame. The load is supported by the frame 1 by contacting with a supporting portion such as a supporting bolt 69 on the frame 1, and by rotating means such as hydraulic mechanisms 66 and 67,
The rotation shaft 64 is rotated about 90 ° forward and backward, and the stopper roller 61 is reciprocally swung between an operating position that traverses the conveyor belt 2 and a retracted position that extends in parallel to the side of the conveyor belt 2. The stopper device of the truck 30 for allocating the vehicle is configured so as to perform the above.

[0005]

The vehicle 30 for vehicle allocation according to the present invention moves by placing the vehicle on the conveyor belt 2 and stops at a position corresponding to the predetermined parking platform 40. During this time, the hydraulic mechanism 6
6 and 67, the stopper roller 61 is arranged in an operating position where the stopper roller 61 crosses over the conveyor belt 2 to prevent the vehicle from moving back and forth. Stopper roller 6 with which wheel W abuts
1 stretches the spring 68 under the load of the vehicle,
It descends with the arm 62. Then, when descending, the arm 62 contacts the upper surface of the support portion 69 of the frame 1. Therefore, the stopper roller 61 and the arm 62 receive the load of the vehicle in cooperation with the frame 1, and the load on the stopper roller 61 and the arm 62 is reduced. When the vehicle 30 for dispatching is stopped at a position corresponding to the parking platform 40,
The hydraulic mechanisms 66 and 67 are operated to move the rotary shaft 64 to the arm 6
2 and the stopper roller 61 together with about 90 ° rotation,
The stopper roller 61 is arranged on the side portion of the conveyor belt 2 in parallel with it, and is retracted. When the stopper roller 61 which is in contact with the wheel W and descends, is slightly separated from the wheel W, the spring 68 causes the spring 68 to return to the upper position together with the arm 62 and separates from the support portion 69 of the frame 1. Therefore, the stopper roller 61 smoothly rotates to reach the retracted position.
Then, the motor M is operated to rotate the conveyor belt 2 to send the automobile onto the parking platform 40. When the vehicle is transferred from the parking table 40 to the vehicle 30 for vehicle allocation, one stopper roller 61 on the receiving side is placed in the retracted position, and the motor M is rotated in the reverse direction. The conveyor belt 22 of the parking pedestal 40 also rotates in the reverse direction, and the automobile is delivered from the parking pedestal 40, placed on the conveyor belt 2 of the truck 30 for vehicle distribution, conveyed to a predetermined position, and abuts on the other stopper roller 61. When the vehicle reaches various positions, one stopper roller 61, which was in the retracted position, is swung to the operating position, and the front and rear movements of the vehicle are restrained by the front and rear stopper rollers 61. Then, the vehicle 30 for vehicle allocation on which the vehicle is placed moves to a predetermined location and sends out the vehicle.
