Abstract

PURPOSE:To minimize an abnormal stop of a car washing device by judging weather a abnormalities detected by various kinds of sensors are at a 1st level, where they may do damage to the car, etc., or at a 2nd level, where they will not give any damage to it, and making stop/continue operations according to the degree of the abnormalities. CONSTITUTION:During car washing operation, a central control unit 25 checks the input/output port conditions of unit control units 26a to 26d to detect abnormality. If occurrence of any abnormality is detected, the abnormality will be judged whether it is at a 1st level, where the abnormality produced by the trouble may do damage to a car body and make the car washing impossible, or at a 2nd level, where it will not do damage to the car body and make the car washing possible for the time being. When it is at the 1st level, all the operations of the units a to d are stopped, the brush nozzle, etc., are retarded once, abnormal-producing locations are displayed in an indicator 65, and the occurrence of abnormality is announced by an audio unit 68. On the other hand, when it is judged that the car washing can be continued, the abnormal location is confirmed by the worker and repair work is made before proceeding with the car washing.

It is composed of a proximity swing f that opens and closes, and is used to change the direction of air blowing. The position of the accompanying blower nozzle 20 is detected. Reference numerals 53 and 54 are sensors for detecting the vehicle body, and these sensors are comprised of photoelectric switches in which a light emitter and a light receiver are attached to face each other on an arch-shaped arm 56 that grows a hanging part 55 with a gap wider than the width of the vehicle at both ends. It moves up and down together with the blower nozzle 20 following the link arm 22, detects the vehicle body before the blower nozzle 20 comes into contact with it, and is used to control the motor 45. A sensor 57 detects when the blower nozzle 20 comes into contact with the vehicle body, and is composed of a microswitch that detects the displacement of an actuating plate 58 provided on the side of the blower nozzle 20 outlet facing the vehicle body. When the entrance detector 31d detects that a car has entered the drying unit d, the blower nozzle 20 configured as described above operates the blowers 19 and 19 to start blowing air, and also operates the motor 45 to start the blower nozzle 20. lower it. When the vehicle body is detected by the vehicle body detection sensors 53 and 54, the blower nozzle 20 is raised and lowered by the motor 45 to operate along the upper surface of the vehicle body. When the drying is completed and the exit detector 32 detects the exit of the car, the blower nozzle 20 is retracted to the upper retract position. Along with these operations, signals from the respective sensors 46, 47, 49 to 54, and 57 are constantly monitored. For example, if the sensor 46 or 47 does not detect that the blower nozzle 20 has reached a predetermined position depending on the timing at which the motor 45 operates, it is determined that there is an abnormality in the operation. Similarly, if a predetermined signal is not inputted from the sensors 49 to 52 with the operation of the air cylinder 48, it is determined that there is an abnormality. Further, if a detection signal is input from the overload detection sensor and sensor 57 built into the motor 45, or a signal indicating a decrease in detection sensitivity is input from the vehicle body detection sensors 53 and 54, it is determined that an abnormality has occurred. Above, front/side brush 5 and blower nozzle 2
