In addition, equipment setting buttons such as front guard, fender pole, door mirror, rear wiper, and no applicable equipment are provided.

  FIG. 3 is a front view showing a main configuration of the top brush 4 of the car wash machine main body 1. The rotation axis 4A of the top brush 4 extends in the left-right direction from the center of the top brush 4, and is rotatably supported by holders 61 provided on the left and right. A rotation motor 60 that rotates the top brush 4 is disposed on the right side and is connected to the rotation shaft 4 </ b> A of the top brush 4 via a transmission mechanism 58. Thereby, the rotation motor 60 rotates the top brush 4.

  The holder 61 includes a right side holder 61A connected to the wire 63A (first wire) and a left side holder 61B connected to the wire 63B (second wire). A first guide roller 62A and a second guide roller 62B are vertically supported on the holders 61A and 61B, respectively.

  Guide parts 59 extending in the vertical direction are provided on both sides of the car wash machine body 1. As will be described in detail later, the guide portion 59 is formed in a U-shaped horizontal sectional view including a front rail 59C (see FIG. 4) and a rear rail 59D (see FIG. 4), and the first guide roller 62A and The second guide roller 62B contacts and rolls. Accordingly, the holders 61A and 61B can be moved up and down by the guidance of the guide portion 59.

  The upper part of the holder 61A on the right side is connected to the wire 63A, and is connected to the winding unit 66 via a pulley 64A disposed above. The upper part of the holder 61B is connected to the wire 63B, and is connected to the take-up portion 66 via a pulley 64B and a pulley 64A disposed above.

  The winding unit 66 is connected to a motor shaft (not shown) of the lifting motor 65, and the holder 61A and the holder 61B are lifted and lowered by the winding of the lifting motor 65. As a result, the top brush 4 is suspended by the wire 63 to maintain a constant distance from the vehicle CA to be cleaned, and can be raised and lowered by driving the lifting motor 65.

  If the use of the car wash machine WA is continued, the wires 63A and 63B change over time due to the weight of the top brush 4, and elongation occurs. At this time, the wire 63B between the holder 61B and the winding unit 66 is longer than the wire 63A between the holder 61A and the winding unit 66. Thereby, if the load applied to the wires 63A and 63B is the same, the elongation of the wire 63B becomes larger than that of the wire 63A.

  For this reason, the rotation motor 60 and the raising / lowering motor 65 which rotationally drive the top brush 4 are arranged on the same one side with respect to the top brush 4. Thereby, the load applied to the wire 63A becomes larger than that of the wire 63B, and the elongation due to secular change can be made uniform on the left and right.

The weight of the top brush 4 and the holder 61 is M ₁ , the weight of the rotary motor 60 is M _2, and the length of the wire 63A between the holder 61A and the winding portion 66 in the frequently used top brush 4 arrangement is L. _1, when the length of the wire 63B between the holder 61B and the winding section 66 and _{L 2,} when determining the weight _M 1, _{M 2} so as to have the relationship of formula (1) more desirable. Thereby, the elongation of the wires 63A and 63B due to secular change can be made substantially the same.

_{L 2 (M 1/2 +} M 2) = L 1 M 1/2 ··· (1)

  Between the pulley 64A and the winding unit 66, a looseness detection unit 75 that detects the looseness of the wires 63A and 63B is disposed. The looseness detection unit detection unit 75 includes a looseness detection unit 75A that detects the wire 63A and a looseness detection unit 75B that detects the wire 63B. The looseness detectors 75A and 75B have tension springs 70A and 70B, levers 71A and 71B, pulleys 69A and 69B, and a looseness detection sensor 74. One ends of the tension springs 70A and 70B are connected to the car wash machine main body 1, and the other ends are fixed to the upper ends of the levers 71A and 71B.

  The levers 71A and 71B are rotatably arranged with the fulcrums 73A and 73B supported by the car wash machine body 1. The pulleys 69A and 69B are rotatably supported at the lower ends of the levers 71A and 71B, and are arranged in contact with the wires 63A and 63B between the pulleys 64A and 64B and the winding portion 66. The looseness detection sensor 74 detects the movement of the levers 71A and 71B. When at least one of the wire 63A and the wire 63B is loosened, the looseness detection unit 72 determines that the operation is abnormal, and the top brush 4 can be stopped from descending and rotating via a control unit (not shown).

  FIG. 4 is a side sectional view of the right guide portion 59. The guide part 59 has two parallel rails 59C and 59D arranged in the front-rear direction. The holders 61A and 61B were provided. The first guide roller 62A rotates about the rotation shaft 62C, and the second guide roller 62B rotates about the rotation shaft 62D.

  The holder 61 </ b> A is connected to the wire 63 </ b> A at the upper part of the top brush 4 at a position away from the rotational axis 4 </ b> A in the rearward direction. As a result, the front of the holder 61A is inclined downward, and the first guide roller 62A moves away from the rear rail 59D and rolls on the front rail 59C. Further, the second guide roller 62B rolls on the rear rail 59D away from the front rail 59C.

  Similarly, the left-side holder 61B is also connected to the wire 63B at a position away from the rotating shaft 4A in the rearward direction. As a result, the first guide roller 62A provided in the holder 61B also moves away from the rear rail and rolls on the front rail. Similarly, the second guide roller 62B moves away from the front rail and rolls on the rear rail.

  The rotation motor 60 is directly connected to the rotation shaft 4 </ b> A of the top brush 4. The motor shaft M of the rotary motor 60 is arranged in parallel to a plane perpendicular to the rotary shaft 4A. In addition, the motor shaft M is inclined backward with respect to the guide direction A of the guide portion 59. Thereby, the center of gravity of the rotary motor 60 is arranged forward with respect to the rotary shaft 4A.

  Therefore, the first guide roller 62A can be separated from the rear rail 59D and rolled on the front rail 59C more reliably. Further, the second guide roller 62B can be separated from the front rail 59C and can be rolled on the rear rail 59D.

  Thereby, even if it has the clearance gap between 1st, 2nd guide roller 62A, 62B and both rails 59C, 59D, the position of the rotating shaft 4A of the top brush 4 can be made constant in the front-back direction. Therefore, since the position of the rotating shaft 4A is constant, the top brush 4 can be rotated stably.

  With the above configuration, the car wash machine main body 1 moves in the front-rear direction relative to the vehicle to be cleaned CA based on the set car wash conditions. Then, the liquid agent is supplied from the liquid storage tank 50 to the vehicle to be cleaned CA, and the rotating brush provided in the car wash machine body 1 slides on the vehicle to be cleaned CA to wash the vehicle to be cleaned CA. At this time, the top brush 4 is moved up and down along the upper surface of the vehicle CA to be cleaned by driving the lifting motor 65 by the detection of the vehicle sensor 8 and cleaned without damaging the upper surface of the vehicle CA to be cleaned. be able to.

  According to this embodiment, since the rotation motor 60 and the lifting motor 65 are arranged on one side with respect to the top brush 4, it is possible to make the elongation due to aging of the wires 63A and 63B having different lengths uniform. Therefore, the rotating shaft 4A of the top brush 4 can be maintained substantially horizontal, and a reduction in the cleaning ability of the car wash machine WA can be prevented. Moreover, since the rotation motor 60 and the raising / lowering motor 65 are arrange | positioned at the same side of the left-right direction of the car-washing machine main body 1, wiring can be concentrated and the car-washing machine main body 1 can be reduced in size.

  The first guide roller 62A moves away from the rear rail 59D and rolls on the front rail 59C, and the second guide roller 62B moves away from the front rail 59C and rolls on the rear rail 59D. Thereby, the position of the rotating shaft 4A in the front-rear direction is constant, and the top brush 4 can be rotated stably.

  Further, since the wires 63A and 63B are connected to the holders 61A and 61B at positions away from the rotating shaft 4A in the rearward direction, the position of the rotating shaft 4A in the front-rear direction can be easily made constant.

  Further, since the axial direction M of the rotary motor 60 is inclined with respect to the guide direction A of the guide portion 59, the position of the rotary shaft 4A in the front-rear direction can be made more certain.

  Further, a winding sensor 67 for detecting the winding amount of the wire 64 is provided, and the winding sensor 67 is arranged on the same right side as the lifting motor 65. Therefore, the height position of the top brush 4 can be accurately grasped, and the wiring of the car wash machine main body 1 can be consolidated and downsized.

  In the present embodiment, the wires 63A and 63B may be connected to the holders 61A and 61B at positions away from the rotation axis 4A of the top brush 4 respectively. Thereby, the guide roller 62A moves away from the front rail 59C and rolls on the rear rail 59D, and the guide roller 62B moves away from the rear rail 59D and rolls on the front rail 59C. At this time, it is more preferable to arrange the center of gravity of the rotary motor 60 rearward with respect to the rotation shaft 4A. Moreover, you may provide the raising / lowering motor 65 and the rotation motor 60 on the left side.

  ADVANTAGE OF THE INVENTION According to this invention, it can utilize for the car wash machine which installs in a gas station etc. and wash | cleans a to-be-washed vehicle.
