A safety current detecting means 60 that is activated when SA is exceeded is provided.

Next, the operation of the embodiment of the present invention having the above configuration will be described.

First, the operation for cleaning the front of the vehicle will be described.

First, as shown in FIG. 1, the frame 4 is stopped at the washing start position, and the vehicle to be washed (for example, the panel van P) is stopped at a predetermined position between the traveling rails 1 and 1. At this time, the side brushes 12A and 12B are at the storage positions indicated by the chain lines in FIG.

When the panel van selection button 50 and the start button 54 provided on the operation panel are pressed from this state, the solenoid valves 34 and 36 are excited (opened). As a result, the air cylinders 12A, 12B both contract by the air supplied from the air source 30 via the non-excited (pressurized) solenoid valves 32, 38, and the first links 18, 18, the second links 19,
The left and right side brushes 12A, 12B move inward while rotating via the 19 and the moving frames 10, 10. When the side brushes 12A, 12B reach the start position (solid line position in FIG. 2) and the start position detection switches S1, S2 are operated, the solenoid valves 34, 36 are switched to non-excited (pressurized) and the side brushes 12A, 12B. Stops at the start position.

At the same time, frame 4 starts going forward,
Eventually, when one of the swing detection switches S5 is activated by the side rails 12A and 12B contacting the front surface of the vehicle body and the guide rail 7 swings, the forward movement of the frame 4 is stopped and the frame 4 is moved backward by a predetermined distance. As a result, the side brush 12
A and 12B contact the front surface of the vehicle body with an appropriate surface pressure.

When cleaning a small car having a low vehicle height, the side brush 12 is not moved until the frame 4 starts moving forward.
A and 12B abut against the front of the vehicle body and the swing detection switch S5
When the small car selection button 53 is pressed, the going distance following the going is made longer than that of the large car when the small car selection button 53 is pressed. Thus, the front of a small car can be washed with the same surface pressure as the front of a large car.

Subsequently, by energizing (opening) the solenoid valve 34, the air cylinder 20A is contracted to move the left side brush 12A from the position (A) in FIG. By energizing (opening) the solenoid valve 38, the air cylinder 20B is extended to move the right side brush 12B from the position (B) in FIG. Thus, both side brush 1
When both the left and right side brushes 12A and 12B move in the direction of arrow R and reach the position (C) in FIG. 4B to operate the closing position detection switch S3, the solenoid valves 34 and 38 are de-energized (energized). Pressure) and both process valves 40
A, 40B are excited (locked) and the air cylinder 20A,

A and 12B are stopped at positions (C) and (D) in FIG. 4B, respectively.

A predetermined time 1 is set by a timer in the control device C.
When the elapse of seconds is detected, the left process valve 40A
Is de-energized (unlocked), the electromagnetic valve 32 is energized (opened), and the air cylinder 20A is extended to move the left side brush 12A in the direction of arrow L. And
When the left side brush 12A reaches the start position (a) in FIG. 4C and the start position detection switch S1 is actuated, the solenoid valve 34 is excited (opened) to stop moving.
At that position, the rotation of the left side brush 12A is stopped.

Simultaneously with the start of the movement of the left side brush 12A in the direction of arrow L, the right side process valve 4
The electromagnetic valve 36 is energized (opened) with 0B de-energized (unlocked), and the air cylinder 20B is contracted to move the right side brush 12B in the direction of arrow L. When the right side brush 12B reaches the closed position (C) in FIG. 4D and the closed position detection switch S4 is operated, the solenoid valve 36 is de-energized (pressurized) to stop the movement, and at the same time, the process is stopped. The valve 40B is excited (locked) to block the flow of hydraulic oil to the right air cylinder 20B.

Therefore, the right side brush 12B is
Move in the direction of arrow L until the closed position (C) of (D) is reached
And when approaching the obstacle such as a back mirror BM and of the left has stopped moving and rotating side brushes 12A
Is pressed by the right side brush 12B as shown in FIG.

And brushing the front of the vehicle closest to each other
(For example, the state shown in FIGS. 4A and 4B)
12A and 12B are shorter than the distance G between centers.
You.

When a predetermined time of 1 second is detected by the timer in the control device C from the state shown in FIG. 4D, the solenoid valve 32 is de-energized (pressurized) to contract the air cylinder 20A. The left side brush 12A is moved in the direction of arrow R, and the rotation is restarted after a lapse of a predetermined time of one second. When the left side brush 12A reaches the start position and the start position detection switch S1 is operated, the electromagnetic valve 34 is de-energized (pressurized) to stop the movement, and at the same time, the process valve 40A is energized (locked).

Simultaneously with the movement of the left side brush 12A in the direction of arrow R, the process valve 40B is de-energized (unlocked), and the electromagnetic valve 38 is energized (opened).
The air cylinder 20B is extended to move the right side brush 12B in the direction of arrow R. Then, when the right side brush 12B reaches the start position and the start position detection switch S2 is operated, the electromagnetic valve 38 is de-energized (pressurized) to stop the movement and to excite (lock) the process valve 40B. As a result, both side brushes 12A and 12B return to the state shown in FIG. 4A, and the cleaning of the front of the vehicle is completed.

The right side brush 12B moves in the order of (b) → (d) → (b) → (c) → (b) and moves between the (c) position and the (d) position. And the left side brush 12B is (A) → (C) → (B) → (E) →
Since it moves as shown in (a) and cleans between the (a) position and the (c) position, no unwashed portion is generated at the center of the window glass W on the front surface F of the vehicle body. Also, the left side brush 1 pressed by the right side brush 12B
When the second brush 2A moves beyond the start position (a) to the (e) position, the left side brush 12A has stopped rotating, so that the rearview mirror BM and the undermirror UM provided at the left end of the front surface F of the vehicle body F. Will not be damaged.

The washing of the front surface F of the vehicle body is the same when any of the panel van selection button 50, the trailer selection button 51 and the truck selection button 52 is pressed, and when the small car selection button 53 is pressed, Only the return distance of the frame 4 for adjusting the surface pressure is different.

In the embodiment for cleaning the front of the vehicle,
The left side brush 12A is a rearview mirror BM or the like.
