When the foam jet car wash is selected as the car wash course, the following washing steps are sequentially executed in accordance with the reciprocation of the car wash machine main body 1. - 特許庁

○ First forward process (Fig. 10)
In the first forward process, along with the forward movement of the car wash main body 1, jet cleaning is performed by injecting high-pressure cleaning water from the high-pressure injection nozzle 10 of the cleaning unit 9 onto the vehicle body surface. The jet cleaning is performed by operating the slide device 19 of the cleaning unit 9 to slide the traveling carriage 13 in the lateral direction while injecting high-pressure cleaning water from the high-pressure injection nozzle 10 .

At the beginning of the first forward process, before the car wash machine main body 1 starts the forward movement, the tilt device 26 is operated to direct the washing unit 9 toward the inside of the car wash machine main body 1, and the washing water is discharged from the high-pressure injection nozzle 10. is injected toward the front of the vehicle body (Fig. 10a). This is an operation for compensating for insufficient washing of the vicinity of the front end of the vehicle caused by the washing unit 9 being installed at a position protruding forward from the front surface of the car washing machine main body 1 by a predetermined distance L.

After that, the washing unit 9 is returned to the horizontal position, and the injection direction of the high-pressure injection nozzle 10 is vertically downward. 10b). Due to the sliding of the traveling carriage 13, the high-pressure injection from the high-pressure injection nozzle 10 acts over the entire vehicle width of the vehicle, and the upper surface and side surfaces of the vehicle body are evenly washed.

When the car wash machine main body 1 moves forward and the photoelectric switch 35a passes through the rear end of the car body and changes to light transmission, the tilt device 26 is operated to direct the washing unit 9 toward the inside of the car wash machine main body 1, and the high-pressure injection nozzle is turned on. 10 sprays washing water toward the rear surface of the vehicle body (Fig. 10c). At this time, the washing effect can be enhanced by temporarily stopping or decelerating the traveling speed of the car washing machine main body 1 .

After that, when it is detected that the car washing machine main body 1 has traveled a predetermined distance by receiving a pulse signal from the travel encoder 4, the washing unit 9 is returned to the horizontal posture, the washing unit 9 is stopped, and the first forward process ends. (Fig. 10d).

In this first forward process, the pulse signal of the traveling encoder 4 may be received and the vehicle body detection result of the vehicle body detector 34 may be taken in to detect the traveling position of the car wash machine main body 1 and create vehicle shape data. . In this case, the washing water splashed by the high-pressure jet of the washing unit 9 may affect the detection of the vehicle body by the vehicle body detector 34 . In particular, when the washing unit 9 is directed toward the inside of the car washing machine main body 1 to jet wash the rear surface of the vehicle body (FIG. 10c), there is a possibility that the jet from the washing unit 9 may directly adhere to the vehicle body detector 34 . Therefore, when the photoelectric switch 35a passes through the rear end of the vehicle body and becomes translucent, the taking-in of the vehicle body detection result of the vehicle body detector 34 is stopped, and the rest of the vehicle shape data is created in the subsequent brushing process. is desirable. Further, it is desirable to equip the front face of the vehicle body detector 34 with an opening/closing type lid so that the lid can be closed when the intake is stopped.

○ First return process (Fig. 11)
In the first return process, along with the return movement of the car wash machine main body 1, foam spraying of spraying foam detergent on the vehicle body surface from the foam spraying nozzle 11 of the washing unit 9 is executed. Foam spraying is performed by spraying the foam detergent from the foam spraying nozzles 11 while operating the slide device 19 of the washing unit 9 to slide the traveling carriage 13 in the horizontal direction in the same manner as jet washing.

When the first return process starts, before the car wash machine main body 1 starts the return process, the tilt device 26 is operated to move the washing unit 9 to the position where the car wash machine main body 1 completes the first return process. 1, the traveling carriage 13 is slid by the slide device 19, and the foam spraying nozzle 11 sprays the foam detergent toward the rear surface of the vehicle body (Fig. 11a).

After that, the car wash machine main body 1 starts to go back, and when the photoelectric switch 35a goes back to the position where the light is blocked by the rear end of the car body, the washing unit 9 is returned to the horizontal posture, and the sliding of the traveling carriage 13 by the slide device 19 is maintained. While doing so, the spray direction of the foam spraying nozzle 11 is returned to vertically downward (Fig. 11b).

As the car wash main body 1 goes around, the foam detergent is evenly sprayed on the upper and side surfaces of the vehicle body (Fig. 11c). When the car wash machine body 1 returns to the car wash start position, the tilt device 26 is actuated to orient the washing unit 9 toward the inside of the car wash machine body 1, and the foam spray nozzle 11 sprays the foam detergent toward the front of the vehicle body. (Fig. 11d). After that, when a predetermined time has passed, the cleaning unit 9 is returned to the horizontal posture, the cleaning unit 9 is stopped, and the first forward process ends.

Thus, after the washing unit 9 performs foam jet washing as the car wash machine main body 1 reciprocates, the same car washing process as before is executed as the car wash machine main body 1 makes 1.5 reciprocal travels.

That is, in the second forward process, the pulse signal of the traveling encoder 4 is received and the vehicle body detection result of the vehicle body detector 34 is taken in, the traveling position of the car wash machine body 1 is detected, the vehicle shape data is created, and the liquid agent is sprayed. Shampoo and wax spraying pipes 38 and water spraying pipes 39 spray washing water from a pipe 37, and the upper surface washing brush 8 and the side washing brushes 9, 9 are brought into contact with and separated from the vehicle based on the detected vehicle shape to brush and wash. is done.

In the second return process, cleaning water is sprayed from the liquid agent spray pipe 37 and the water spray pipe 39, and wax (or water repellent agent) is sprayed from the chemical spray pipe 38 based on the vehicle shape data created in the second forward process. Perform a brushing wash. At this time, washing water may be injected at high pressure from the high-pressure injection nozzle 10 of the washing unit 9 to perform rinsing.

Further, in the third forward process, the drying nozzles 5, 6, 6 are applied to each surface of the vehicle body based on the vehicle shape data created in the second forward process, and blow drying is performed by high-pressure air.
