Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic cleaning device for cleaning guard wax and the like.

Generally, when a new car is stored or transported, guard wax is applied to the surface of the car to prevent the painted surface from getting sunburned or scratched by sand.

Conventionally, there is a cleaning device shown in FIG. 1 for removing this guard wax. This apparatus is composed of a belt conveyor 1, a preheating shower 2, a top dewaxer 3, a side dewaxer 4, a rinse arch 5, a brush unit 6, and an air dryer 7.

First, one wheel of the target vehicle is placed on the belt conveyor 1 and conveyed at a predetermined speed. First, warm water is sprayed from the preheating shower 2 to warm the surface of the car. Next, a solvent mixed with hot water and kerosene is sprayed from above the vehicle from the top dewaxer 3 to remove the guard wax applied to the top surface of the vehicle. Next, a solvent is sprayed from both sides of the car from the side dewaxer 4 to remove the guard wax applied to both sides of the car. Thereafter, clean water is sprayed from the rinse arch 5 to wash away the guard wax and solvent adhering to the surface of the automobile.

Then, the guard wax that has not been dissolved by the top dewaxer 3 and the side dewaxer 4 is rubbed off by the brush unit 6. Finally, the air dryer 7 dries the moisture adhering to the vehicle body.

However, this device has the drawbacks of increasing equipment costs and requiring a large installation space because the equipment is large and the work process is organized into a line. Moreover, by forming the work process into a line, a belt conveyor 1 for transporting the automobiles is required, which has the disadvantage of complicating the equipment accordingly.

This invention was made in order to eliminate the above-mentioned drawbacks.A guide is supported on a pillar so as to rotate left and right following the movement of the center of gravity, and the guide is directed toward the top of the target vehicle along this guide. By running the first washer that sprays the cleaning liquid on both sides of the vehicle, and the second washer that sprays the cleaning solution on both sides of the target vehicle, the configuration is significantly improved. The present invention aims to provide an automatic cleaning device that can be simplified.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

In FIGS. 2a and 2b, 11a and 11b are a pair of supports suspended from the floor;
A support shaft 12 is installed between 1b. This support shaft 1
2, guides (groove-shaped steel in the illustrated example) 13a and 13b are rotatably supported so as to rotate left and right following the movement of the center of gravity. This pair of guides 13a,
13b indicates the front line of the vehicle 14, which is the part located on the left side of the figure when the part on the right side of the figure is held horizontally by a stopper or the like with the support shaft 12 as a fulcrum, as shown in FIG. 2b. It is formed in a dogleg shape to follow the .

In addition, as shown by the two-dot chain line in the figure, 13a, 13
The vehicle type (body shape) is adjusted so that b does not come into contact with the rear part of the car 14 when it rotates to the right in the figure.
Guides 13a and 13b are moved by stopper etc. according to the
The angle of inclination is regulated. Furthermore, both ends of the pair of guides 13a, 13b are connected by connecting rods 15a, 15b so that they rotate synchronously.

A first washer 16 is movably provided on the pair of guides 13a and 13b. This first washer 1
6 is a truck 18 equipped with a pair of axles 17a and 17b.
A pair of injection nozzles 20a and 20b are provided which are swung left and right by a swiveling cam mechanism 19. A cleaning liquid, for example, a solvent made by mixing kerosene with warm water, is sprayed from the injection nozzles 20a, 20b toward the upper surface of the target vehicle 14.

The washer 16 is conveyed at a predetermined speed using a rope transmission 21 in the illustrated example of the drive system. The rope transmission device 21 includes a rope pulley 23 having spiral rope grooves formed at both ends of a driven shaft 22 connected to a drive motor capable of forward and reverse rotation via a speed reducer, and the guide 13.
A plurality of guide wheels 2 arranged in a straight line on a and 13b
4 with a rope 25 installed thereon, and the trolley 18 is connected to the rope 25 via a connecting fitting 26.

On the other hand, 27a and 27b are the guides 13a and 1
This is a second washer that is self-propelled along both sides of the automobile 14 arranged under the vehicle 3b. This second washer 27
a, 27b are rocking devices 30a, 3 on carts 29a, 29b running on guide rails 28a, 28b.
Nozzles 31a, 31 that swing up and down by 0b
b is attached.

Next, the operation of this embodiment will be explained.

First, the rope transmission 21 is driven to clean the first washer 1.
6 to the left in the figure, the center of gravity shifts to the left, causing the first guides 13a, 13b to rotate counterclockwise. At this time, the guides 13a, 13
b is regulated by a stopper so that the right side is horizontal as shown by the solid line in the figure. Then, with the first washer 16 moved to the left side of the guides 13a, 13b, the target automobile 14 is carried under the guides 13a, 13b as shown in the figure.

Next, the rope transmission 21 is driven to clean the first washer 1.
6 in the right direction in the figure at a predetermined speed. When the first washer 16 passes through the support shaft 12 and moves to the right side in the figure, the center of gravity moves from the left side to the right side, so the guides 13a and 13b rotate clockwise. At this time, the left side of the first guides 13a, 13b is held substantially horizontally as shown by the two-dot chain line in the figure, and the first guides 13a, 13b are held by the stopper so that the right side is along the rear part of the automobile 14.
rotation is restricted. Accordingly, the automobile 14 is connected to the nozzles 20a and 20b which are oscillated in the direction of the arrow in the figure by the oscillating cam mechanism 19 of the first washer 16.
The solvent is sprayed onto the top surface of the The guard wax applied to the upper surface of the automobile 14 is washed away by this solvent.

On the other hand, the second cleaning devices 27a and 27b are moved to the left side in the figure in advance, and after the automobile 14 is brought in, they are made to run rightward in the figure at a predetermined speed. At this time,
The solvent is sprayed toward both sides of the automobile 14 while vertically swinging the nozzles 31a and 31b.
As a result, the guard wax applied to both sides of the automobile 14 is washed away in the same manner as described above.

Finally, the automobile 14 is moved forward and carried out.

Therefore, with such a configuration, the first guides 13a and 13b rotate as the center of gravity moves.
By providing the washer 16 in a movable manner, the configuration can be significantly simplified, so that construction can be easily performed and the installation space can be reduced.

Moreover, by driving a car to load in from one side and take out from the other, conveyor belts and other conveyance equipment can be protected, which simplifies the configuration and reduces work time. can do.

Note that the present invention is not limited to the above-mentioned embodiments, and can be implemented with various modifications without changing the gist.

For example, in the above embodiment, when the guide rotates, the guide is bent so that the left side roughly follows the front line of the car and the right side roughly follows the rear line.
The present invention is not limited thereto, and the guide may be formed in a straight or curved shape.
