Description

Detailed Description of the Invention A1 Objective of the Invention (1) Industrial Application Field The present invention is a vehicle cleaning method in which the outer peripheral surface of a vehicle is cleaned by side brushes that are rotatably driven around a rotating shaft disposed in the vertical direction. This invention relates to a side brush device in an apparatus.

(2) Prior Art Conventionally, in vehicle cleaning apparatuses, side brush devices have been known that clean the side surfaces and front and rear surfaces of a vehicle using side brushes that rotate around a vertical axis.

By the way, the side surface shape of an automobile is generally formed such that the width of the upper part of the car body is smaller than the width of the lower part of the car body, so if the diameters of the side brushes are made the same on the top and bottom, the surface pressure of the side brushes will be lower. This causes an inconvenience in that the value becomes too large at the bottom and too small at the top. For this purpose, side brushes are used in which the diameter of the side brushes is made larger at the upper part and smaller at the lower part, and the diameter of the side brushes is made larger at the upper part and smaller at the lower part, and the diameter of the side brushes is connected with a tapered part in the middle to equalize the brush surface pressure against the side of the car body. (For example, see Japanese Patent Publication No. 48-33929)
.

(3) Problems to be Solved by the Invention However, the angle of inclination of the side of the body of a passenger car-type vehicle is relatively large, whereas the angle of inclination of the side of the body of a wagon-type vehicle is formed to be relatively small. However, it has been difficult to efficiently clean the side surfaces of the vehicle bodies of both types of vehicles using side brushes of the same shape.

In addition, when cleaning the front and rear surfaces of a vehicle with the conventional side brushes whose lower diameters are smaller, when the left and right side brushes are brought close to each other, the upper brush bristles, which have larger diameters, repel each other. The brushes on both sides could not be brought close enough together. For this reason, a gap is created between the lower portions of the side brushes having a small diameter, making it impossible to sufficiently clean the central portion of the front and rear surfaces of the vehicle (near the license plate mounting portion).

Furthermore, since the side brush rotates around a vertical axis, in vehicles where the bumper protrudes significantly from front to back, there is a problem in that the upper surface of the bumper, which is a horizontal surface, cannot be sufficiently cleaned.

The present invention was made in view of the above-mentioned circumstances, and it is possible to efficiently wash both passenger car type and wagon type vehicles, and it is also possible to clean the front and rear surfaces of the vehicle and the top surface of the bumper. It is an object of the present invention to provide a side brush device in a vehicle washing device that can efficiently wash the vehicle.

B1 Structure of the Invention (1) Means for Solving the Problems In order to achieve the above object, the side brush device in the vehicle cleaning device of the present invention is mounted on a frame that is movable in the longitudinal direction relative to the vehicle to be cleaned. A pair of movable bodies supported so as to be able to approach and move away from each other in the direction, a pair of brush support members pivotally supported by each movable body so as to be swingable in the left and right directions, and a brush support member pivotally supported by each brush support member and driven to rotate. and a pair of side brushes.

(2) Effect According to the above configuration, when cleaning both side surfaces of a vehicle with a pair of side brushes, by inclining the side brushes in accordance with the inclination angle of the side surfaces of the vehicle, uniform surface pressure can be achieved. The side of the vehicle can be washed.

When cleaning the front or rear side of a vehicle with left and right side brushes in contact with each other, the side brushes are tilted so that their upper and lower parts are in close contact with each other even if the diameters of the upper and lower side brushes are different. This ensures that the central portion of the front and rear surfaces of the vehicle is cleaned. Furthermore, by slanting the side brushes, the bristles pass obliquely from top to bottom against the top surface of the bumper, so that the top surface of the bumper is reliably cleaned.

(3) Examples Hereinafter, the present invention will be explained in detail based on the drawings.

1 to 7 show a first embodiment of the present invention, in which FIG. 1 is a front view of the side brush device, FIG. 2 is a sectional view taken along the line ■-■ in FIG. 1, and FIG. is the ■direction arrow view in Figure 2, and the 4th
FIG. 5 is a diagram showing how the front side of a passenger car type vehicle is cleaned; FIG. 5 is a diagram showing how the side surface of a passenger car type vehicle is cleaned;
FIG. 6 is a diagram showing the cleaning state of the side surface of a wagon type vehicle, and FIG. 7 is an explanatory diagram of the operation.

As shown in FIGS. 1 to 3, this vehicle washing device includes a gate-shaped running frame 3 supported on a running rail 1 laid on the floor via left and right wheels 2 so as to be able to move forward and backward. There is. A pair of left and right carts 5 as movable bodies are supported by a plurality of rollers 6 on guide rails 4 disposed in the left-right direction on the upper part of the traveling frame 3. The tip of an arm 8 pivoted on a bracket 7 provided on the running frame 3 is connected by a pin 11 to the tip of a link IO pivoted on a bracket 9 fixed to the trolley 5, and also connected to a cylinder pivoted on the running frame 3. Twelve rods 13 are connected to the middle part of the arm 8. Wire 14 with one end tied to each trolley 5
is guided to the side of the traveling frame 3 via a pulley 15, and a weight 16 is provided at the other end.

Therefore, due to the expansion of the cylinder 12, both carriages 5
moves outward along the guide rail 4 and opens the rod side and anti-rod side of the cylinder 12, so that both bogies 5
move inward toward each other due to the weight of the weights 160.

A cylindrical brush support member 17 is pivotally supported on each truck 5 by a pin 18 so as to be able to swing left and right, and a side brush B is provided at the lower part of a rotating shaft 19 that is rotatably supported by the brush support member 17. It is being

A motor 21 is attached to a bracket 20 fixed to the upper end of the brush support member 17, and a driving sprocket 22 of the motor 21 is connected to a driven sprocket 23 of the rotating shaft 19 via a chino 24. Thereby, the driving force of the motor 21 is transmitted to the rotating shaft 19, and the side brush B is rotated in either the forward or reverse direction.

A pair of cylinders 26 and 27 connected in series are mounted between a bracket 25 extending laterally from the truck 5 and a bracket 20 fixed to the brush support member 17. Therefore, when the cylinder 26 is extended and the cylinder 27 is contracted, the side brush B is maintained in the vertical position (a), but when both cylinders 26 and 27 are extended, the left and right side brushes B are 18, and assumes the outward tilted position (b) with its lower end expanded, and conversely, both cylinders 26.
When both the brushes 27 are contracted, the left and right side brushes B assume an inwardly inclined position (c) with their lower ends close to each other.

In addition, the reference numeral 28 in FIG. 1 is a stopper for regulating the inner end position of the cart 5, and the reference numeral 29 is a stopper for regulating the outer end position of the cart.

Next, the operation of the first embodiment of the present invention having the above-described configuration will be explained.

As shown in FIG. 7, the cylinder 12 is opened and the weight of the weight 16 moves the left and right carts 5 to the inner end position (a) where they contact the stopper 28, and the pair of cylinders 26 and 27 are both contracted. The left and right side brushes B are placed in an inwardly inclined position as shown in FIG. From this state, side brush B
While rotating the frame in the direction shown by the solid arrow,
When the side brush B reaches the position (b) and a detection device (not shown) detects the front surface of the vehicle V, the running frame 3 is stopped. When a predetermined period of time has elapsed after the traveling frame 3 stopped, the cylinder 12 expands and the side brush B
moves toward the outer end position (c). At this time, as is clear from Fig. 4, the lower portions of the side brushes B with smaller diameters are inclined so that they approach each other, so the brushes B on both sides are in contact with each other over their entire lengths in the vertical direction without any gaps. ing. Therefore, the front central portion of the vehicle body (near the license plate mounting portion) can be reliably washed.

Further, due to the inclination of the rotating shaft 19 of the side brush B, the bristles pass obliquely from top to bottom against the upper surface of the bumper V1 of the vehicle (2), so that the upper surface of the bumper V1 can be reliably cleaned.

When the side brush B reaches the outer end position (c) and the cart 5 contacts the stopper 29, the side brush B is reversely rotated in the direction indicated by the dashed arrow and the traveling frame 3 is moved while moving the side brush B inward. Let it go again. As a result, the side brush B moves to the position (d) and cleans the side surface of the vehicle V.

At this time, if the vehicle V is a passenger car type with large side surfaces, both cylinders 26, 2? By extending both side brushes B and placing the left and right side brushes B in an outwardly inclined position as shown in FIG. 5, the surface pressure of the side brushes B is made uniform in the vertical direction. On the other hand, if the vehicle V is a wagon type vehicle with a small side slope, the left and right side brushes B can be placed in a vertical position by extending the cylinder 26 and contracting the cylinder 27, as shown in FIG. , the surface pressure of the side brush B can be made uniform. Detection of whether the vehicle V is a passenger car type or a wagon type is performed by detecting the vehicle height using a conventionally known ultrasonic detector or photoelectric switch, and based on the detection signal, the side brush B The inclination angle of the rotating shaft 19 can be controlled.

In this way, when the cleaning of the side surface of the vehicle V is completed and the side brush B reaches the position (e), the traveling frame 3 is made to go back in the opposite direction, and when the side brush B reaches the position (e), The traveling frame 3 is stopped. Next, the side brushes B are brought into the inward tilting position again as shown in Fig. 4, and the rear surface of the vehicle V is cleaned while moving the trolley 3 outward. When the side brushes B reach the position (g), Cleaning is complete. In this process of cleaning the rear surface of the vehicle V, the central part of the rear surface and the top surface of the bumper can be reliably cleaned by the same effect as in the process of cleaning the front surface described above.

8 and 9 show a second embodiment of the present invention, FIG. 8 is a front view of the side brush device, and FIG. 9 is a front view of the side brush device.
FIG. In this embodiment, the same components as those in the previous embodiment are given the same reference numerals.

As shown in the figure, the side brush device of this embodiment includes a first arm 30 whose one end is pivotally supported on the traveling frame 3, and a second arm 30 as a movable body which is pivotally supported at the tip of this first arm 30 with a pin 31. An arm 32 is provided. A brush support member 17 is attached to a pin 18 at the tip of the second arm 32 bent downward.
The roller 33 provided at the upper end of the second arm 32 engages with a guide rail 34 arranged in the left-right direction on the upper part of the traveling frame 3.

The first arm 30 swings left and right by a cylinder 35 mounted between it and the traveling frame 3, and its range of swing is regulated by a pair of stoppers 36 and 37.

A rotating shaft 19 that is rotationally driven by a motor 21 is supported on the brush support member 17, and a side brush B is provided at the lower part of this rotating shaft 19. The brush support member 17 and the second arm 32 are connected by a pair of cylinders 26 and 27 connected in series.

According to this embodiment, the first arm 30 swings by expanding and contracting the cylinder 35, and the movement causes the second arm 3 to swing.
The brush support member 17 that is transmitted through the side brush B moves left and right along the guide rail 34 together with the side brush B. Furthermore, by expanding and contracting the pair of cylinders 26 and 27, the side brush B can be swung between the vertical position (a), the outwardly tilted position (b), and the rightward and inwardly tilted positions (c) around the pin 18. move.

Therefore, with the above configuration of this embodiment, it is possible to obtain the same effects as those of the previous embodiment.

Although the embodiments of the present invention have been described above in detail, the present invention is not limited to the embodiments described above, and various small design changes may be made without departing from the scope of the invention described in the claims. It is possible to do so.

For example, in the above embodiment, the side brush B is configured to take three postures: a vertical posture, an outwardly inclined posture, and an inwardly inclined posture. It may be configured to take only an inclined posture. Also,
The diameter of the side brush B does not necessarily have to be the same as the upper tool (the diameter may be the same on the top and bottom.In addition, instead of moving the running frame 3 with respect to the stopped vehicle V, it is possible to fix the frame side It is also possible to move the vehicle V with respect to this frame.

C1 Effects of the Invention According to the above-described invention, when cleaning both side surfaces of a vehicle with a pair of side brushes, the side brushes can be tilted to match the inclination angle of the side surfaces of the vehicle. It is possible to efficiently clean everything from vehicles with a large side surface inclination angle to vehicles with a small side surface inclination angle, such as a wagon type.

In addition, when cleaning the front or rear side of a vehicle with the left and right side brushes in contact with each other, even if the diameters of the upper and lower side brushes are different, the side brushes are tilted so that their upper and lower parts are in close contact with each other. This makes it possible to reliably wash the central portion of the front and rear surfaces of the vehicle.

Furthermore, by slanting the side brushes, the bristles can be passed obliquely from top to bottom against the top surface of the bumper, so that the top surface of the bumper can be reliably cleaned.
