When the indicator lamp 45 is turned on, the notification state is set by the character string 42.

  The display unit 38 is formed in a plate shape and is disposed at the front part of the upper surface 35 a of the gantry 35. The display unit 38 is provided with a character string 43. The character string 43 is composed of a character string such as “exit” for instructing the vehicle to be cleaned CA to exit. As will be described in detail later, the character string 42 of the display unit 37 is covered by the display unit 38 when the movable unit 36 is disposed at the retracted position S1 (see FIG. 6).

  FIG. 5 is a front view showing the inside of the gantry 35. An electromagnetic valve 51 connected to a compressor (not shown) via a regulator 56 is provided in the gantry 35. A check valve 53 is provided at the port 51 c on the primary side of the electromagnetic valve 51. The secondary-side ports 51a and 51b of the solenoid valve 51 are connected to the ports 48a and 48b of the double-acting air cylinder 48 via pipes 52b and 52c, respectively. As a result, the solenoid valve 51 supplies air, which is a working fluid, to the air cylinder 48.

  When the solenoid valve 51 is not energized, air is supplied to the port 48b of the air cylinder 48, and the rod 48c of the air cylinder 48 is contracted. At this time, the air in the air cylinder 48 is exhausted from the exhaust port 51d through the pipe 52b. Thereby, the movable part 36 is arranged in the retreat position S1 retreated from the travel path R as shown in FIG.

  When the solenoid valve 51 is energized, air is supplied to the port 48a of the air cylinder 48, and the rod 48c of the air cylinder 48 extends downward. At this time, the air in the air cylinder 48 is exhausted from the exhaust port 51e via the pipe 52c. As a result, the movable portion 36 is disposed at the advance position S2 that advances forward of the vehicle CA to be cleaned on the travel path R as shown in FIG.

  Since the movable portion 36 is disposed at the retracted position S1 when the solenoid valve 51 is not energized, the retracted position S1 is retained when a power failure occurs. Thereby, the collision with the movable part 36 at the time of a power failure and the to-be-cleaned vehicle CA can be avoided.

  In addition, when the supply of air from the compressor is stopped when a power failure occurs, the check valve 53 prevents the backflow of air, so that the air in the air cylinder 48 is prevented from flowing out. For this reason, it can prevent that the movable part 36 distribute | arranged to evacuation position S1 is distribute | arranged to advance position S2 with dead weight.

  Further, as shown in FIG. 6, the center of gravity G of the movable portion 36 at the retracted position S1 is disposed on the side farther from the travel path R than the support portion 35d of the connecting member 46. At this time, an angle formed by a line L1 connecting the center of gravity G of the movable part 36 and the support part 35d and a vertical line L2 passing through the support part 35d on the projection plane perpendicular to the axial direction of the support part 35d and the support part 35c. θ is set to 10 ° or more.

  If the angle θ is smaller than 10 °, the movable portion 36 at the retreat position S1 may be disposed at the advance position S2 against the check valve 53 due to strong winds during a power failure. By forming the angle θ to be 10 ° or more, it is possible to more reliably prevent the movable portion 36 from being placed at the advanced position S2 due to its own weight even if a strong wind occurs during a power failure.

  The arm 47b of the connecting member 47 is provided with a substantially rectangular plate-like member 54 that protrudes toward the traveling path R side. When the movable portion 36 is disposed at the retracted position S1, the space between the arm 47b and the side surface 35e of the mount 35 is covered by the plate-like member 54. Thereby, it is possible to prevent the fingers of the user or the staff from being sandwiched between the arm 47b and the side surface 35e of the mount 35.

  In the car wash machine WA having the above-described configuration, the user drives to stop the vehicle to be cleaned CA in front of the remote panel 7A, and sets the car wash conditions for the vehicle to be cleaned CA from within the vehicle to be cleaned CA. When the setting of the car wash conditions is completed, the movable portion 36 is arranged from the retracted position S1 to the advanced position S2 by energization of the electromagnetic valve 51.

  Then, the indicator lamp 45 is turned on to enter a notification state by the character string 42, and a forward movement is instructed by the display unit 37. The user moves the vehicle CA to be cleaned forward with reference to the notification of the indicator light 45 and the character string 42 that emits blue light. When the vehicle to be cleaned CA is disposed at a predetermined car wash start position, the indicator lamp 45 is turned off and the indicator lamp 44 is turned on. Thus, the notification state is switched to the character string 41 and the display unit 37 instructs to stop.

  The user stops the vehicle to be cleaned CA, and the car wash machine main body 1 starts car washing when it is confirmed that the vehicle to be cleaned CA has stopped at the car wash start position. When the car wash is started, the car wash machine main body 1 moves in the front-rear direction, and the rotating brushes rotate to wash the vehicle CA to be cleaned. Following the cleaning of each rotating brush, air is blown from each blowing nozzle toward the vehicle to be cleaned CA, the vehicle to be cleaned CA is dried, and the washing of the vehicle to be cleaned CA is completed.

  FIG. 7 is a top view of the car wash WA in a state where the car wash has been completed. When the washing of the vehicle to be cleaned CA is completed, the solenoid valve 51 is de-energized and the movable part 36 is retracted from the advance position S2 to the retract position S1.

  Then, the indicator lamp 44 is turned off and the indicator lamp 45 is turned on. Thereby, the character string 42 of the display unit 37 is covered by the display unit 38 and switched to the notification state by the character string 43, and the display unit 38 instructs to leave.

  According to the present embodiment, the air cylinder 48 (fluid cylinder) is disposed above and below the arm 47c in the axial direction, and when the rod 48c contracts, the movable portion 36 is disposed at the retracted position S1 and the rod 48c is disposed. When extending downward, the movable portion 36 is disposed at the advance position S2. Thereby, the mount frame 35 can be made small in the left-right direction, and the installation space of the car wash machine WA can be reduced in size. Moreover, since the rod 48c of the air cylinder 48 is disposed in a contracted state when the movable portion 36 is placed in the retracted position S1, the rod 48c can be prevented from being rusted. Therefore, the maintenance frequency of the car wash machine WA can be reduced and the convenience can be improved.

  Further, a check valve 53 is provided on the primary side of the electromagnetic valve 51 that supplies the working fluid to the double-acting air cylinder 48, and the movable portion 36 is switched from the retracted position S1 to the advanced position S2 by energization of the electromagnetic valve 51. Thereby, since the solenoid valve 51 becomes the retreat position S1 side at the time of a power failure, the movable part 36 can be held at the retreat position S1. Further, even if the supply of air to the electromagnetic valve 51 is stopped during a power failure, the check valve 53 can prevent the backflow of air and keep the movable portion 36 at the retracted position S1. Therefore, it is possible to avoid a collision between the vehicle to be cleaned CA and the movable portion 36 at the time of a power failure.

  Further, the support portion 35d (second support portion) of the connection member 46 (second connection member) is arranged between the support portion 35c (first support portion) of the connection member 47 (first connection member) and the travel path R. Is done. Then, on the projection plane perpendicular to the axial direction of the support portion 35c and the support portion 35d, an angle θ formed by a line L1 connecting the gravity center G of the movable portion 36 and the support portion 35d and a vertical line L2 passing through the support portion 35d. Was increased to 10 ° or more. Thereby, even if a strong wind occurs at the time of a power failure, it can prevent more reliably that the movable part 36 is distribute | arranged to advance position S2 with dead weight.

  Further, the mounting portion 55 at the upper end of the air cylinder 48 is disposed between the support portion 35c and the support portion 35d in the horizontal direction on the projection plane perpendicular to the axial direction of the support portion 35c and the support portion 35d. Thereby, the magnitude | size of the left-right direction of the mount frame 35 can be made smaller.

  In the present embodiment, a hydraulic cylinder may be used instead of the air cylinder 48. Alternatively, the air cylinder 48 may be a single acting type and the check valve 53 may be omitted.

  ADVANTAGE OF THE INVENTION According to this invention, it can utilize for the car wash machine and the car wash method provided with the movable display part which guides a to-be-washed vehicle.
