At this time, the top brush device 20 drives the motor 29 to rotate the top brush shaft 27 via the chain 33 and the like, thereby rotating the top brush 26. When washing a vehicle, the vehicle height detection device 13
The actuating device 40 is actuated on the basis of the learning data of the vehicle height learning in which the shape is detected, and the top brush 26 is forcibly moved to a predetermined upper and lower position and then positioned.

That is, the motor 42 of the actuating device 40 is positively operated to normally rotate the passive sprocket 45 through the drive sprocket 44 and the chain 46. Then, the locking body 47 integrated with the passive sprocket 45 is brought into contact with the surface 49a of the locked body 49, and the rotation shaft 21 is rotated in the forward direction against the own weight of the top brush 26 side, and the arm is moved.

When the top brush 26 washes the upper surface side of the vehicle 18 to be cleaned, basically the top brush 26
The top brush 26, the arm 23, and the like make the weight 26 contact (press-contact) with the upper surface side of the vehicle to be cleaned 18 while receiving the balanced load of the weight 34.

During such movement, a passive sprocket
The through hole 52 formed in 45 is rotated (moved) in front of the pulse encoder 51, and the number of passages thereof is counted by the first counter 53, whereby the operation amount of the operation device 40, that is, the movement of the top brush 26. The quantity is detected by the first detection device 50.

This operation amount, that is, the count value from the first counter 53 enters the second subtractor 66, and the second subtractor 66
At, the target operation amount and the count value based on the learning data or the like are subtracted. The subtracted value enters the control unit 67 as the target deviation value F, and the control by the control unit 67 causes the motor 42 to operate normally or reversely as described above.
As a result, the count value (operation amount) from the first detection device 50
Gradually changes, and when the target deviation value F is [0], the motor 42 is automatically stopped and locked. Thereby, based on the detection by the first detection device 50, the actuator 40
The movement to the positioning position by can be arbitrarily and easily controlled, the movement position can be positioned, and the learning control can be easily performed.

During the operation of the operating device 40 as described above, the rotary encoder 56 is rotated integrally with the rotary shaft 21, and the rotation amount is counted by the second counter 58, whereby the rotary shaft 21 is rotated. Is detected by the second detection device 55, that is, the actual movement amount of the top brush 26.

The detection values from both detectors 50 and 55, that is, the count values from both counters 53 and 58 are the first subtractor.
The difference is subtracted at 61 and is input to the first comparator 62 as the operation deviation value E. Here, the operation deviation value E is compared with a preset allowable range value α, and if it is within the allowable range value α, it will not be output to the 1-pulse generator 63 side. The rotation is controlled as described above.

Thus, when an overload (strong contact pressure) is applied to the top brush 26 during car washing,
Since the upward movement force of 26 acts in the direction in which the locked body 49 separates from the locking body 47, the top brush 26 is automatically moved upward without any trouble, thereby eliminating the overload. To be done.

At that time, the actual amount of rotation of the rotary shaft 21 becomes small, and the detected value from the second detecting device 55 becomes low. As a result, when the operation deviation value E subtracted by the first subtractor 61 is input to the first comparator 62 and compared with the allowable range value α, a state of exceeding the allowable range value α occurs, and at this time, one pulse It will be output to the generator 63 side. Then, switching is performed by the pulse signal from the 1-pulse generator 63.
64 is turned on once, thereby changing the target operation amount, that is, the target deviation value F, and the motor 42 is rotationally controlled as described above.

Therefore, the rotation shaft 21 is rotated by the amount of change in the target deviation value F, that is, by one pulse, and the rotation causes the locking body 47 to move closer to the locked body 49. Become. The pulse signal from the one-pulse generator 63 is intermittently output, and the locking body 47 is brought into contact with the surface 49a of the locked body 49, whereby the motor 42 is stopped.

As described above, the correction control means 60 can correct (actuate) the actuating device 40 to automatically prevent the locking body 47 from being separated from the locked body 49 more than necessary. Therefore, the soft car wash posture can always be maintained stably.
At that time, both the detection devices 50 and 55 are operated near the arm 23 to perform detection with less error.

As described above, when the car wash main body 1 is reciprocated and the top brush device 20 is used to wash the upper surface of the vehicle 18 to be washed, a soft car wash is particularly suitable for the single brush 28 made of cloth. Easy to do.

By operating the actuating device 40 as described above, as shown by the solid and phantom lines in FIGS. 3 and 4,
The arm 23 moves through the locked body 49 and the rotary shaft 21 to rotate the rotary shaft 21.

The same can be applied to a stationary car washing machine that performs car washing.

In the above embodiment, the first detection device 50
Although the pulse encoder 51 and the like are used for the second detection device 55 and the rotary encoder 56 and the like are used for the second detection device 55, this may be reversed, and the pulse encoder 51 and the like may be used for both detection devices 50 and 55. The format used, both detectors 50,
Both 55 may use a rotary encoder 56 or the like. Furthermore, another configuration may be adopted as both the detection devices 50 and 55.

In the above-described embodiment, the passive sprocket 45 is also used as the rotating body, but in the present invention, the rotating body may be provided separately.
In the embodiment described above, the form in which the cloth single brush 28 is laminated as the top brush 26 is shown, but in the present invention, an example using a side brush made of conventional resin brush bristles is also possible. .
