DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a rocker brush device for a car wash machine, which is employed to operate a rocker brush in a car wash machine.

BACKGROUND ART In a conventional car wash machine, for example, as seen in Japanese Utility Model Publication No. 61-34917, a pair of left and right lower side cleaning brushes (rocker brushes) are attached to the main body of the car wash machine via arms. The arms are provided with driving motors, and are configured to be able to move toward and away from each other via the arms.

Problems to be Solved by the Invention In the conventional type described above, the rocker brush cleans the lower half of the vehicle body including the wheels from a part of the rocker.

When the wheels are cleaned with such a rocker brush, the rim 36 and wheel cap 3 are removed as shown in FIG.
In the corner portion 38 formed by 7, especially the portion 3 on the rotation direction 39 side
8a becomes insufficiently cleaned. A possible solution to this problem is to use a round brush with hard bristles, but this tends to damage the tire 40, rim 36, hubcap 37, etc.

SUMMARY OF THE INVENTION An object of the present invention is to provide a rocker brush device for a car wash machine that can thoroughly clean the entire area of a wheel even if soft, long bristles are used.

Means for Solving the Problems In order to achieve the above object, the rocker brush device for a car wash machine according to the present invention includes a pair of left and right holding frames that are provided in the main body of the car wash machine so as to be able to approach and separate from each other. An arm and a rocking device are provided that are swingable around the center, and the arm is provided with a rocker brush and a rotating device that are rotatable around a rotation axis that is perpendicular to the left-right axis.

According to the configuration of the present invention, the rocker brush is rotated around the rotation axis by the rotating device, and by moving both the holding frames toward each other, the rocker brush is moved around the vehicle body including the outer surface of the wheel. Normal cleaning can be performed by touching the lower half. Then, while the car wash machine body is stopped or slowed down with the rocker brushes in contact with the outer surface of the wheels, the rocker brushes are swung around the left-right axis via the arm by the swinging device. It is possible to displace the insufficiently cleaned portion on the rotational side of the brush around the left-right axis, and as a result, regular cleaning can be performed over the entire area.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 to 7.

A gate-shaped car wash machine main body 1 is connected to a rail 3 via a plurality of wheels 2.
It is mounted on top and runs! ! The robot can freely travel back and forth on a fixed route by operating a moving device W (not shown). The car wash machine #1 includes a first washing water arch 4, a first wax arch 5, a second washing water arch 6, and a second wax arch 7.
and a detergent arch 8 are arranged in this order, and a top nozzle 9 and a side nozzle 10 for drying are provided at the location of the first washing water arch 4, and a top brush 11 is provided.
and the side brush 12, respectively, on the swingable arm 1.
It is attached via 314. Rocker brushes 15 are provided at the lower portions of both sides of the car wash main body 1 so as to be movable toward and away from each other. That is, an L-shaped holding frame 16 is provided when viewed from the front, and this holding frame 16 is supported on the car wash machine main body 1 side by a pair of left and right links 17.
It is configured to be able to swing left and right while maintaining its posture, and a cylinder device 18 for swinging is provided between the link 17 and car wash machine book #1. The horizontal frame portion of the holding frame 16 supports a horizontal shaft 20 that is rotatable around a left-right axis 19, and this horizontal shaft 20 swings via a transmission device 21 disposed within the vertical frame portion. It is operatively connected to the device 22. Note that the swinging device 22 includes an electric motor, a cylinder device, and the like. An arm 23 bent at right angles is attached to the inner end of the horizontal shaft 20, and this arm 23 is swingable around the left-right axis 19. Furthermore, a rotary shaft (vertical shaft) 25 is attached to the inner end of the arm 23 and is rotatable around a rotary shaft center 24 that is orthogonal to the left-right direction shaft center 19, and this rotary shaft 25 is integrated with the brush shaft. The rocker brush 15 is attached in a shape. The rotating shaft 25 is operatively connected to a rotating device 27 such as an electric motor via a transmission device 26. 3G
