Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a side brush for cleaning front and rear surfaces and both side surfaces of a vehicle, and a brush device for a car washer that is a brush mechanism of the side brush.

2. Description of the Related Art A conventional car wash machine equipped with this type of brush device is
It will be described with reference to FIGS.

The conventional car washer includes a gate-type car washer body 2 that straddles a vehicle 1 to be washed and can travel in the direction of arrow A, which is the front-back direction of the vehicle 1, a top brush 3 that is vertically rotatable, and a car wash. It is provided with a pair of side brushes 4 which can be moved toward and away from each other in the direction of arrow B, which is a direction perpendicular to the traveling direction of the machine body 2, and a pair of rocker brushes 5 which can be moved toward and away from each other in the direction of arrow B. The pair of side brushes 4 are vertically suspended by brush drive shafts 8 on a pair of movable frames 7 which are slidable on a horizontal arm 6 which is horizontally mounted on the upper portion of the car wash machine body 2.
The pair of moving frames 7 are slid by the arms 9 of the link mechanism so as to move toward and away from each other on the horizontal arm 6 at the same time, and the moving frame 7 is commanded by a control device (not shown). Accordingly, a motor mechanism (not shown) for rotating the side brush 4 via the brush drive shaft 8 is installed therein. Further, as shown in FIG. 7, the horizontal arm 6 is rotatably supported in a bearing 11 on a frame 10 of the car wash main body 2 by a support shaft 12 in the directions of arrows C and D in the traveling direction of the car wash main body 2. It is supported, and a swing arm 14 biased from both sides by a neutral spring 13 is fitted on the support shaft 12. The car wash main body 2 is provided with a limit switch 15 which is turned on when the swing arm 14 is moved in the direction of arrow C by the rotation of the horizontal arm 6.

With the above structure, the car wash machine body 3 can be used during the washing process.
In the direction of arrow A, pressing the top brush 3, the side brush 4 and the rocker brush 5 against the vehicle 1 while rotating the top brush 3, the top surface of the vehicle 1 with the top brush 3 and the front and rear of the vehicle with the side brush 4. The lower surface of both sides of the vehicle is cleaned by the rocker brush 5 on both sides and both sides. Also,
As shown in FIG. 8, the first side brush 4a, which is one of the pair of side brushes 4, comes into contact with the protrusion 16 of the vehicle 1 such as a side mirror, and the horizontal arm 6 rotates to cause the limit switch 15 to move. Is stopped, the car wash machine body 2 stops running,
By widening the distance between the pair of side brushes 4 by the arm 9 of the link mechanism, the vehicle travels a certain distance to avoid the protrusions 16,
The spacing between the side brushes 4 is returned to the original state and the cleaning by the side brushes 4 is restarted.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in the conventional apparatus for the side brush 4, since the horizontal arm 6 is composed of one arm, the pair of side brushes 4 are placed obliquely as shown in FIG. When the front surface of the car 1 that has been scraped is washed, the first side brush 4a comes into contact with the car 1 so that the horizontal arm 6 has an arrow C shown in FIG.
When the second side brush 4b is rotated in the direction of, the second side brush 4b is also rotated, which is an unnecessary movement for the second side brush 4b, the contact force to the vehicle 1 is reduced, and the cleaning force is reduced. Further, on the front surface of the vehicle 1 with which the first side brush 4a is in contact, a force for supporting the pair of side brushes 4 and the horizontal arm 6 is exerted, and further, the side brush 4 in contact with the side brush 4 is contacted first.
Requires a force to rotate the other side brush 4 as well, and thus an unnecessary contact pressure is required. As a result, the front surface of the vehicle 1 may be scratched or the one side brush 4 may be unnecessarily damaged. Further, as described with reference to FIG. 8, when the first side brush 4a comes into contact with the protrusion 16 of the vehicle 1 while cleaning both side surfaces of the vehicle 1, the first and second side brushes 4a and 4b are The control is performed to widen the interval to avoid the protrusions 16, and the cleaning of both side surfaces of the vehicle 1 by the first and second side brushes 4a and 4b is restarted again, so that the second side brush 4b avoids them. However, there was a problem that the point 17 on the side surface was left uncleaned. Further, the protrusion 16 of the vehicle 1 may be damaged due to the force that similarly supports the pair of side brushes 4 and the horizontal arm 6.

The present invention solves the above problems and eliminates unnecessary movement of each of a pair of side brushes to ensure cleaning and prevent damage to the vehicle, as well as a contact for rotating the side brushes. It is an object of the present invention to provide a brush device for a car wash machine in which the pressure is distributed to each side and the side brush is prevented from being damaged.

Means for Solving the Problems In order to solve the above problems, the present invention is a brush device for a car wash machine that is provided in a main body of a car wash machine that straddles a vehicle to be washed and can travel in the front-rear direction of the vehicle. There, a pair of side brushes for cleaning the front and rear surfaces and both side surfaces of the vehicle, and a pair of horizontal arms that are horizontally crossed at a right angle to the traveling direction of the car wash main body, respectively, on the upper part of the car wash main body. The pair of side brushes are provided slidably on each of the horizontal arms so as to be slidable in a direction perpendicular to the traveling direction of the car washer main body, and each of the pair of horizontal arms is driven by the main body of the car washer. It is configured to rotate in any direction,
A second aspect of the invention is the addition of the rotation detecting means for detecting that each of the pair of horizontal arms has rotated to the first aspect of the invention.

Effect According to the configuration of the first aspect of the present invention, when the car washer body is traveling to wash the vehicle, the lateral brushes of the respective horizontal arms are pushed by the vehicle to push the side brushes. Rotate in the machine running direction. Therefore, when the horizontal arm is rotated by one of the side brushes, the other side brush is prevented from rotating together, and two conventional side brushes are vertically attached to the one horizontal brush. The force on the vehicle is about half that of the configuration.

Further, in the second invention, in addition to the operation of the first invention,
By detecting the rotation of each horizontal arm by the rotation detecting means, each side brush is controlled so as to avoid the protrusion of the vehicle that comes into contact with each side brush. Therefore, unlike the conventional case, the avoidance operation of one side brush prevents the other side brush from avoiding operation together.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. The same members as those of the conventional example shown in FIGS. 6 and 7 are designated by the same reference numerals and the description thereof will be omitted.

FIG. 1 shows a brush device for a car washing machine according to the present invention. In FIG. 1, reference numeral 21 denotes a central frame at the upper part of the gate-type car wash main body 2, and a pair of first frame 21 provided on the central frame 21 and the first side frame 22 on the upper right side of the car wash main body 2. The first horizontal arm 25 is rotatably supported in the running direction of the car wash main body 2 indicated by the arrow E by the pair of support shafts 24 on the first bearing 23. The pair of second bearings 27 provided on the upper left second side frame 26 and the pair of second support shafts 28 are connected to the second horizontal arm 29.
Is rotatably supported in the direction of arrow E. The right and left side brushes 4a and 4b are installed on the horizontal arms 25 and 29 on the guide rails 34 and 35, respectively, by the moving frames 7a and 7b, and when the side brushes 4 are inclined, the first and second side brushes 4a and 4b are respectively placed. A sliding device in which a detector (not shown) is operated by levers 30 and 31 fixed to the second support shafts 24 and 28a, and each side brush 4 is separately installed according to the output of the detector. (Cylinder and lever, etc.) (not shown) slides on the guide rails 34, 35. As a result, the first and second moving frames 7a and 7b slide in the direction perpendicular to the traveling direction of the car wash machine body 2 (direction of arrow F). In addition, neutral springs are attached to the support shafts 24b and 28b on the first and second side frames 22 and 26, respectively.
First and second swing arms 14a and 14b urged by 13 are fitted.

With the above configuration, the first horizontal arm 25 and the second horizontal arm
Each of the 29 is independently rotatable. Therefore, as shown in FIG. 2, when the front surface of the vehicle 1 or the like placed obliquely is washed, if the first side brush 4a comes into contact with the front surface of the vehicle 1, the first side brush 4a moves through the first moving frame 7a to move the first side brush 4a. Since only the first horizontal arm 25 rotates and the second side brush 4b does not rotate together with the first side brush 4a, the contact force of the second side brush 4b with the vehicle 1 is maintained and the cleaning force is maintained. Can be secured. Further, as compared with the conventional example shown in FIG. 5, the first side brush 4a comes into contact with the vehicle 1.
Since only the first side brush 4a and the first horizontal arm 25 are applied to the front surface of the vehicle, the load on the front surface of the vehicle 1 is reduced to about half, so that the scratches and damages generated on the front surface of the vehicle 1 are reduced. can do. Also, damage to the side brush 4 itself is reduced.

Next, the second invention will be described with reference to FIGS. 3 and 4. The configuration of FIG. 3 is different from that of the first invention shown in FIG. 1 in that the levers 30 and 31 are provided when the first and second horizontal arms 25 and 29 are rotated in the directions of arrow G, respectively. The first and second limit switches 36 and 37, which are rotation detecting means provided at positions where the first and second limit switches 36 and 37 are respectively operated, are added. The rotation of the two horizontal arms 25, 29 is detected (see FIG. 4).

According to the configuration of the second invention, as shown in FIG. 5, the vehicle 1 has the protrusion 16 and the first side brush 4a has the protrusion 16.
When the first horizontal arm 25 is rotated in contact with the first limit switch 36 and only the first limit switch 36 is operated, the first side brush 4a is controlled to avoid the protrusion 16 and the second side brush 4a is operated. The side brush 4b can be washed along the side surface of the vehicle 1 as it is, and the problem of leaving a portion which is not washed can be solved.

In the configuration of the second invention shown in FIG. 3, the first and second limit switches 36 and 37 are used as the rotation detecting means, but of course the lever 3 is used as the rotation detecting means.
It is possible to use means such as detection based on the angles of 0, 31 and the angles of the first and second swing arms 14a, 14b.

EFFECTS OF THE INVENTION As described above, according to the present invention, a pair of horizontal arms are provided on the upper part of the car wash main body in a direction perpendicular to the traveling direction of the car wash machine main body, and a pair of side brushes are installed on the horizontal arm. Each of the horizontal brushes is vertically slidable in the direction perpendicular to the running direction of the car wash machine, and each of the horizontal arms is configured to be rotatable in the running direction of the car wash machine. Since the other side brush does not rotate due to the rotation of the rack arm, the catalyst of the other side brush to the vehicle is held, so that the cleaning force by the other side brush can be maintained without being reduced. further,
Compared with the conventional configuration in which two side brushes are vertically installed on one horizontal arm, the force exerted on the vehicle portion contacted by the side brushes is about half, and the vehicle portion acts as a side brush. The horizontal arm does not apply excessive pressure and can prevent damage due to it, and can also reduce damage to the side brushes and the like. Further, according to the second invention, in addition to the effect of the first invention, by providing the rotation detecting means for detecting the rotation of each of the horizontal arms, the side brushes of the respective side brushes are provided. It is possible to perform control to avoid a vehicle protrusion or the like that is touched and pushed, and therefore one side brush and the other side brush do not both perform the avoiding operation as in the conventional case. It is possible to eliminate the fact that there is a part that is not cleaned by performing the avoidance operation. Further, it is possible to prevent unnecessary contact pressure from being applied to the side brush.
