Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a brush device for a car wash machine.

[0002]

2. Description of the Related Art Conventionally, a general car washing machine has a gate-shaped frame composed of left and right side frames and an upper frame connecting upper ends of the respective side frames. A brush parallel to the upper frame) and a side brush (brush whose rotating shaft is parallel to the side frame) are provided so as to be rotatable and positionally controllable (also referred to as a gate type car wash machine). Further, in these brushes, a brush material is radially planted on a rotary shaft, and the external shape of the brush is a substantially cylindrical shape centered on the rotary shaft.

In this type of car wash machine, traveling wheels mounted on the lower portions of the side frames are placed on rails and travel across a vehicle to be washed while the above brushes are used to provide the upper surface and front and rear surfaces of the vehicle body. And wash both sides. The front and rear surfaces of the vehicle are cleaned by a pair of left and right side brushes.

The car wash machine is shown in FIG. 8 when the side brush is shown as the center. As shown in the figure, the left and right side brushes a, a are suspended from the carriages b, b, and the left and right side brushes a, While rotating a, the carriages b and b are made to travel on the guide rail c1 along the upper frame c to be opened and closed, and the left and right side brushes a and a are narrowed and widened to be opened and closed to open and close the vehicle d. Brush and clean the front and back surfaces of the.

Here, some vehicles, such as the jeep type vehicle shown in FIG. 9, have a spare tire f mounted on the rear surface of the vehicle and have a step on the rear surface. When a vehicle of this type is washed with a conventional car washing machine, if the portal frame is positioned so as to correspond to the rear surface of the spare tire f, the side brush a on one side hits the spare tire to wash it, but on the other side There is a problem that the side brush a cannot contact the rear surface of the vehicle to clean it, and if the side brush a is adapted to the rear surface of the vehicle, the spare tire f and the side brush a on one side interfere with each other to cause cleaning.

In order to solve the above problem, in the car washing machine, as shown in FIGS. 9 and 10, the moving mechanism of the side brushes a moves the carriages b on one common guide rail g. And, the guide rail g is tilted (the guide rail is tilted against the repulsive force of the spring h or the guide rail is positively tilted by a cylinder or the like), and the side brushes a, a are tilted in the front-rear direction for cleaning. It is conceivable to use a technology for
(See the bulletin, etc.) However, in the above technique, since the left and right side brushes a and a are both tilted to the same displacement when the vehicle is detected, a vehicle having the above-mentioned step does not hit the vehicle uniformly and is left unwashed.

Further, as understood from FIG. 10, the pressing force of the side brush a is reduced at the lower portion of the spare tire f, so that the cleaning force is reduced.

Further, as shown in FIG. 11, in a vehicle such as a wagon vehicle whose vehicle height is high and the rear surface is vertical, the force F _{S of the} spring h is constant when the vehicle is detected by the side brush a. In addition, the force F _B applied to the vehicle is F _S = F _A × A (1) F _S = F _B × B (2) ∴F _B = F _A × (A / B) In this case, B is the distance from the side brush tilting center where the force F _B acts, F _A is the force applied at the lower end of the side brush, and A is the side brush tilting center where the force F _A acts. Is the distance. In the vehicle of the type described above, the force F _B becomes extremely large, which causes a problem that damage to the vehicle body surface and abrasion of the brush increase.

[0009]

As described above, in the conventional car washer, in the case where the vehicle has a step on the front surface or the rear surface, such as a jeep type vehicle, the pressing force of the brush at the lower portion of the tire is used. Therefore, there is a problem in that the cleaning power is reduced due to a decrease in the vehicle surface, and that in a vehicle with a high vehicle height such as a one-box type vehicle, there is a risk of damage to the vehicle surface and wear of the brush increases. The present invention provides sufficient cleaning power even in a vehicle shape vehicle having a step on the front surface or the rear surface,
It is also an object of the present invention to provide a brush device for a car wash machine that does not damage the vehicle body surface of a vehicle with a high vehicle height and does not cause wear of the brush.

[0010]

In order to solve the above-mentioned problems, the present invention has the following constitution. That is, the invention of claim 1 has a gate-shaped frame composed of the left and right side frames and the upper frame connecting the upper ends of the respective side frames, and the left and right trolleys for the left and right carriages moving on the guide member.

In the brush device of the embodiment, when the left and right slide units 16L and 16R are closed, the left and right slide units are brought into contact with the closing stoppers 48b at the ends of the guide rails 29L and 29R on the center line O side. 16
When the L and 16R are positioned at a predetermined interval,
The left and right side brushes are swung (overlapped) beyond the vehicle width center (corresponding to the center line C), and
The left and right side brushes 16L and 16R are swung so that the left and right side brushes do not interfere with each other.

In the car wash machine of the embodiment, in addition to the above-mentioned structure, the shaft is parallel to the upper frame 12 and moves up and down to wash the top brush 51 of the vehicle 20 and a motor for rotating the top brush. 52, a guide rail 53 for lifting the top brush, a rocker brush 55 for cleaning tires, etc.
It has a rocker brush rotation motor 56, a top nozzle 57 that blows air from above toward the vehicle 20, and a side nozzle 58 that blows air from the side.

The operation of the embodiment will be described. When washing the vehicle 20 in the car wash machine of the embodiment, first, the vehicle 20 is positioned in front of the car wash machine and the width center of the vehicle is aligned with the center line O of the gate-shaped frame 14. After that, the side brush drive cylinder 47 is controlled as shown in the upright position in FIG. 4 to make the side brushes 18L and 18R stand upright to start rotation, and the side brush opening / closing cylinder 36 is driven as shown in FIG. The open wires 37 and the interlocking wire ropes 38 are transmitted to the slide units 16L and 16R to close the slide units 16L and 16R (positioned by the stopper 48a at the closed end), and the side brushes 18L and 18
R is located near the center line O. When it is detected by the limit switch 48b1 at the closed end that the units 16L and 16R are located at the closed end, the portal frame 14 of the car wash machine is moved forward in the vehicle direction.

When the side brushes 18L, 18R hit the front surface 20a of the vehicle, the guide rails 29L, 29R swing and the vehicle detection limit switch 49 operates.
When the limit switch 49 is actuated, the side brushes 18L and 18R are pressed against the front surface 20a, rotated and brushed for cleaning, and the front surface 20a is entirely cleaned by the opening operation. At this time, the front surface 2 of the vehicle
If 0a has no step, as shown in FIG. 2, the guide rails 29L and 29R are similarly pushed to the opposite side in the traveling direction of the car washer, but are stopped at a fixed position by the repulsive force of the spring 43. Further, even if the front surface 20a has some irregularities, the guide rails 29L and 29R can be separately swung to allow the side brushes 18L and 18R to sufficiently follow the irregularities.

After the slide units 16L and 16R are brought into contact with the stopper 48b at the closed end so that the left and right slide units 16L and 16R are positioned and stopped at a predetermined interval in the central portion of the upper frame 12, the above-mentioned drawing is performed. The air of the side brush drive cylinder 47 is controlled to the left swing and the right swing shown in FIG. 5 to swing the left and right side brushes 18L and 18R left and right to swing laterally beyond the vehicle width center. Then, the central portion of the vehicle width is washed without being left unwashed. At the time of this swing, the side brushes 18L and 18R are swung in a parallel state or a substantially parallel state at the same timing so that the left and right side brushes do not interfere with each other.

After the cleaning of the vehicle front surface 20a by the side brushes 18L and 18R is completed, the side brush 1
Open 8L and 18R to slide unit 16
When L and 16R come into contact with the open stopper 48a and the open limit switch 48a1 detects that the open end has been reached, the car washer is advanced toward the rear of the vehicle, and at that time,
As shown in FIG. 6, the side brush drive cylinder 47 is controlled as in the state of “C” in FIG. 5, and the side brushes 18L and 18R are balanced with the weight 41 and pressed against the side surface of the vehicle 20 for cleaning as shown in FIG. To do. As a result, even if the side surface of the vehicle has a strong inclination, or if the vehicle height is high and there is a difference in width between the upper portion and the lower portion, the side brushes 18L and 18R are inclined corresponding to the inclination, 20 side surfaces can be washed without leaving any residue. Also, the side brush 18L,
Since the weight of the weight 41 is used to incline 18R, the side surface of the vehicle can be washed without being left unwashed without providing a device having a complicated structure for inclining the brush. At the same time, the top brush 51 cleans the upper surface of the vehicle, and the rocker brush 55 cleans the lower portion of the vehicle side surface and the tire.

Further, as the car washing machine advances, the vehicle rear surface 20b
To move forward from the set position for cleaning the side brush 18
Close the L and 18R and move backward to the side brush 1
Press 8L and 18R against the rear surface of the vehicle. Since the spare tire 20c is attached to the rear surface 20b of the vehicle 20 and has a step, when the side brushes 18L and 18R are pressed, the left and right guide rails 29L corresponding to the step,
29R swings separately on the horizontal plane, and the left and right side brushes 18L and 18R can be applied and brushed for cleaning in correspondence with the step. Therefore, the side brush 18L,
18R are displaced without being influenced by each other, and in the above case, the left side brush 18L is normal and the right side brush 18R.
Even if the vehicle rear surface 20b is displaced due to displacement, or has unevenness, there will be no unwashed residue due to the step or the like.

When the side brushes 18L and 18R are used to wash the front surface 20a or the rear surface 20b of the vehicle, the side brushes 18L and 18R brush beyond the center position O. The vehicle width center position will overlap. Therefore, the front surface 20a and the rear surface 20 of the vehicle 20 are
It is possible to surely wash the center portion of the vehicle width b without washing. Therefore, the front surface, the rear surface, and the side surface of the vehicle can be washed without any washing residue.

The brush device of the car washer according to the present invention is not limited to the above-mentioned one. For example, as shown in another embodiment of FIG. 7, the left and right guide rails 60L and 60R are arranged in the width direction of the vehicle 20. It can be made to rock. In this case, the guide rails 60L and 60R are arranged along the traveling direction of the car wash machine, one end of which is pivotally supported by the upper frame 12 and the other ends of which the side brushes 18L and 18R are suspended. Then, the side brushes 18L, 18R are configured to move back and forth within a certain range while being given a repulsive force by the spring 61 at the other ends, so that the car washer advances to press the side brushes 18L, 18R against the rear surface of the vehicle. In this case, since the side brush 18R retracts on the protruding side and the side brush 18L does not retract on the non-projecting side, even if the vehicle rear surface 20b has a step,
Can be thoroughly washed. In addition, the guide rails 60L, 60R
The rocking can be performed by the cylinder 62. According to the above embodiments, since the drive device for moving the side brush is attached to the inside of the swing arm or to the outer surface of the arm, it is possible to reduce the size of the brush again in the main body of the car wash machine by reducing the size of the other device. Improves installation flexibility.
