Further, as shown in FIG. 7, each holder body 32 is provided with a lower brush rotating motor 58 for rotating the lower brush body 52 and an upper brush rotating motor 59 for rotating the upper brush body 51 in the vertical direction. A driving sprocket 60 coaxially fixed to the rotating shaft of the lower brush rotating motor 58 and a driven sprocket 61 coaxially fixed to the upper end of the shaft 42 are connected by a chain 62, and the rotating shaft of the upper brush rotating motor 59 A drive sprocket 63 fixed coaxially to the upper outer cylinder 54 and a driven sprocket 64 fixed coaxially to the upper outer cylinder 54 are connected by a chain 65.
[0027]
That is, the rotational force of the lower brush rotating motor 58 is transmitted to the lower outer cylinder 56 via the drive sprocket 60, the chain 62, the driven sprocket 61, and the shaft 42, and the lower brush body 52 is rotated, and the upper brush is rotated. The rotational force of the motor 59 is transmitted to the upper outer cylinder 54 via the drive sprocket 63, the chain 65, and the driven sprocket 64, and the upper brush body 51 is rotated. As described above, the side brush 16 is formed of the upper brush body 51 and the lower brush body 52 to which a large number of brush hairs 55 and 57 are attached and connected to each other. It is configured to be able to rotate.
[Action of side brush]
The effect | action by the structure of such a side brush 16 is demonstrated.
[0028]
When the lower brush rotating motor 58 is rotated, the lower brush body 52 is rotated to rotate the brush bristles 57, and when the upper brush rotating motor 59 is rotated, the upper brush body 51 is rotated to rotate the brush. When the bristles 55 are rotated and the bristles 55 of the upper brush body 51 come into contact with the front / rear surface of the vehicle 2 or the upper half surface of the vehicle, the upper half surface is washed, and the bristles 57 of the lower brush body 52 are When the front and rear surfaces of 2 or the lower half surface of the side surface are contacted, the lower half surface is cleaned.
[0029]
As described above, since the lower brush body 52 and the upper brush body 51 can be driven to rotate independently, one of the lower brush body 52 and the upper brush body 51 can be stopped or rotated in opposite directions. Further, when a protrusion such as a side mirror is provided on the side surface of the vehicle 2, if the upper brush body 51 is stopped at the position of the protrusion, the brush hair 55 is entangled with the protrusion or the protrusion is The possibility that the brush body 51 is damaged due to the rotation of the brush body 51 can be avoided. At this time, the remaining lower brush body 52 can be less washed by continuing the cleaning. Further, by arranging the lower brush rotating motor 58 and the upper brush rotating motor 59 in the vertical direction, the structure of the holder 22 is simplified and lightened.
[0030]
Further, the holder main body 32 travels in the left-right direction by rotating the travel motor 34. At this time, when the holder main body 32 moves to the open limit position О, the open limit sensor 49 operates to stop traveling in the open direction, and when the holder body 32 moves to the close limit position S, the close limit sensor 47 operates to move in the closing direction. Is stopped. In addition, the position sensor 46 composed of a pair of left and right photoelectric switches detects the unevenness of the position detection body 30a and measures the travel position of the holder body 32, thereby enabling the position control of each side brush body 23 in the left-right direction. The position of each side brush body 23 can be controlled in accordance with the arrangement and shape of the vehicle 2. In addition, since the self-propelled system that travels by the travel motor 34 is adopted, the configuration is simplified as compared with the conventional case where the holder body 32 is traveled by expansion and contraction of the cylinder rod.
[0031]
Further, when the holder body 32 of the left traveling holder 22a is traveling in the left direction in the closing direction, the side brush body 23a comes into contact with the side surface of the vehicle 2 and is pressed to tilt the side brush body 23a and the right inclination detection sensor 45a operates. The motor 34 is stopped and the traveling of the left traveling holder 22a is stopped. Thus, the travel is stopped in a state where the side brush body 23a is tilted to the right (outside), and the side surface of the vehicle 2 is washed in the tilted state. Further, when the side brush body 23a is pushed more strongly by the side surface of the vehicle 2, or when the traveling motor 34 runs away, the holder body 32 is opened by the sliding action of the torque absorber 33 of the holder body 32 of the left traveling holder 22a. The vehicle 2 and the side brush body 23a are prevented from being damaged.
[0032]
Similarly, when the holder body 32 of the right traveling holder 22b is traveling right in the closing direction, the side brush body 23b is pressed against the side surface of the vehicle 2 and the side brush body 23b is tilted, and the left tilt detection sensor 45b operates. The traveling motor 34 is stopped and the traveling of the right traveling holder 22b is stopped. As a result, the travel is stopped in a state where the side brush body 23b is tilted to the left (outside), and cleaning is performed in the tilted state. Further, when the side brush body 23b is pressed more strongly by the side surface of the vehicle 2 or when the traveling motor 34 runs away, the holder body 32 is opened by the sliding action of the torque absorber 33 of the holder body 32 of the right traveling holder 22b. The vehicle 2 and the side brush body 23b are prevented from being damaged.
[0033]
Thus, the pressing force of the vehicle 2 by the side brush body 23 can be regulated by the torque absorber 33, and the side brush body 23 is prevented from being excessively pressed against the vehicle 2. Further, since the cleaning is performed in accordance with the side surface shape having the angle of the vehicle 2 with the side brush body 23 tilted, the cleaning is performed even if the horizontal length of the brush bristles 55 of the upper brush body 51 is shortened. be able to.
[0034]
When the guide rail 21 tilts rearward or forward, that is, when the side brush body 23 comes into contact with the front or rear surface of the vehicle 2 and tilts to a predetermined angle α, first, the first front / rear tilt detection sensor 28 is operated, and subsequently When tilted to an angle β (β> α), the second longitudinal tilt detection sensor 29 operates. When the first front / rear inclination detection sensor 28 is operated, the relative movement of the car wash machine main body 1 and the vehicle 2 is stopped, and the front or rear surface of the vehicle 2 is washed by moving in the closing direction by the side brush main bodies 23a and 23b. When the second back-and-forth tilt detection sensor 29 operates, an emergency stop is performed, and a recovery operation is performed.
