Nevertheless, also in a state where the vehicle body is detected or the like, which is impossible, the abnormality of the vehicle body detecting means is determined.

Next, the operation of the embodiment will be described. In the embodiment, an example will be described in which cleaning is performed by low-speed traveling in the forward process and drying is performed by low-speed traveling in the returning process. FIG.
As shown in (a), the car A performing car washing stops at a predetermined position at the start of car washing, and the operator operates the operation panel 61 provided on the car washing machine main body 1 to designate a car washing course. By pressing the low-speed start key 64, the car wash is started.

In the car washing process, as shown in FIGS. 9 (b) and 9 (c), the car washer body 1 starts running, and the photoelectric switch for detecting the height of the car detects the car body. First, the photoelectric switch that detects the height H1 of the lower part of the car,
The space between the light emitter 10a and the light receiver 10b is shielded by the vehicle body, and the vehicle body is detected. The car washer stores the running position of the car washer body 1 detected by the running position detecting rotary encoder 5 in the memory 56 as the front end position CS of the vehicle A at this time. Next, the height H of the ordinary car roof position
The photoelectric switch for detecting the light emitting device 11 is a light emitting device 11a and the light receiving device 1
The space between 1b is shaded by the vehicle body, and the vehicle body is detected. The car washer stores the running position of the car washer body 1 at this time in the memory 56 as the front end position RS of the roof portion of the car A.
Thereafter, when the photoelectric switch for detecting the height H2 of the roof position of the ordinary car is released from the light blocking by the vehicle body between the light emitter 11a and the light receiver 11b and the vehicle body is no longer detected, the car washer body at this time is turned off. 1 is stored in the memory 56 as the rear end position RE of the roof portion of the vehicle A. In addition, a photoelectric switch for detecting the height H1 of the lower part of the vehicle is provided by the floodlight 1
When the light shielding between the vehicle body 0a and the light receiver 10b is released and the vehicle body is no longer detected, the car washer machine 1
Is stored in the memory 56 as the rear end position CE of the vehicle A.
To memorize. In this manner, the position of the moving car washer body 1 and the detection result of the photoelectric switch for detecting the vehicle body are stored in association with each other, and the shape of the vehicle A is detected as shown in FIG.

When the shape of the car A is detected, the car washer sets the upper nozzle upper limit position by the upper limit position setting means. In the car washer, as shown in FIG. 11, the photoelectric switch for detecting the height H1 at the lower part of the vehicle detects the vehicle body, and the photoelectric switch for detecting the height H2 of the ordinary car roof position does not detect the vehicle body. The upper nozzle limit position is set to the height of H2, the photoelectric switch for detecting the height H2 of the ordinary car roof position detects the vehicle body, and the photoelectric switch for detecting the height H3 of the wagon car roof position is the vehicle body. Is not detected, the upper limit position of the upper nozzle is set to the height H3. In addition, from the front end position RS of the roof portion detected by the vehicle shape detecting means, the safety limit is set to a position before the distance L1 and the ascending limit position is set to the height H3 from the height of H2.
From the rear end position RE of the roof detected by the vehicle shape detecting means, and the safety limit is changed to a position behind the distance L2, and the elevation limit position is changed from the height of H3 to the height of H2. I do. In this way, the ascent limit position indicated by HL is set.

At the same time as detecting the vehicle body and setting the upper nozzle upper limit position, the upper surface cleaning nozzle is controlled to move up and down along the contour of the vehicle body, and the vehicle is washed. The car washer runs at a low speed while spraying washing water from the top washing nozzle and the side washing nozzle.
As shown in (a), the upper surface cleaning nozzle 30 and the photoelectric switches 41a and 41b provided integrally with the upper surface cleaning nozzle 30 detect the vehicle A body, and the upper surface cleaning such that the photoelectric switches 40a and 40b do not detect the vehicle A vehicle body. The nozzle 30 is lifted and lowered to cause the upper surface cleaning nozzle 15 to act on the vehicle body of the automobile A to perform the car washing. When hot water is used as the washing water and the photoelectric switches 40a and 40b are in a light-shielded state due to steam, the upper surface washing nozzle 30 is judged to have detected the body of the automobile A and rises. Is held at the height of the lift limit position HL, so that the upper surface cleaning nozzle 30 and the vehicle body of the automobile A are not separated more than necessary. Thereafter, the photoelectric switches 40a, 40b and 41a, 4
1b, the upper surface cleaning nozzle 30
As shown in FIG. 12 (c), the lift is controlled at the height of the lift limit position HL, and the car washing is continued.

When the outgoing washing process is completed, the car washer enters a returning drying process. The car washer activates the blower and runs at a low speed while injecting high-pressure air from the upper surface drying nozzle and the side surface drying nozzle. At this time, if the abnormality of the photoelectric switch of the upper surface drying nozzle is detected by the upper surface drying nozzle raising / lowering photoelectric switch abnormality signal input 59, the car washer is set in the forward process as shown in FIG. The upper surface drying nozzle 15 is controlled to move up and down at the height of the elevation restriction position HL so that the upper surface drying nozzle 15 and the vehicle body of the automobile A do not separate more than necessary. When the abnormality of the photoelectric switch of the upper surface drying nozzle is released, the photoelectric switches 23a and 23b provided integrally with the upper surface drying nozzle 15 detect the body of the automobile A, as shown in FIGS. The upper surface drying nozzle 15 is controlled to move up and down so that the photoelectric switches 22a and 22b do not detect the vehicle A body, and the upper surface drying nozzle 15 is applied to the vehicle A body to perform drying. To end.

It should be noted that the present invention is not limited to the above embodiment, and various design changes can be made without departing from the scope of the claims. For example, in the embodiment,
Although the car washer having the upper surface cleaning nozzle and the upper surface drying nozzle has been described, the same control can be performed even when a known car washing machine having the upper surface cleaning brush and the side surface cleaning brush is provided with the upper surface cleaning nozzle and the upper surface drying nozzle. Needless to say. Also, in a car washer in which a car is moved so as to pass through a stationary car washer body and the car is washed, the upper surface nozzle can be similarly controlled.

In the embodiment, the shape of the vehicle is detected with four stages of photoelectric switches for detecting the height of the vehicle, and the upper limit position of the upper nozzle is set in accordance therewith. A large number of switches are arranged at fine steps, the vehicle height is finely divided, the vehicle shape is detected, and the upper nozzle upper limit position can be set in fine steps accordingly.

In the embodiment, the upper surface drying nozzle is moved up and down by an air cylinder, and the elevation position is detected by a proximity switch. However, similarly to the upper surface cleaning nozzle shown in the embodiment, the upper surface drying nozzle is also controlled by a motor. Alternatively, the vertical position may be detected by a rotary encoder.

[0041]

As described above, according to the present invention, the upper surface nozzle is brought close to the vehicle body while the upper surface nozzle is approached to the vehicle body while the vehicle body is detected by the vehicle body detection means provided integrally with the upper surface nozzle. When performing the above, based on the vehicle shape detected by the vehicle shape detection means, the upper limit nozzle upper limit position is set, so that the vehicle body detection means detects the vehicle body regardless of the presence or absence of the vehicle body for some reason Even if
The upper surface nozzle can be controlled up and down below the height of the set upper limit position without raising the upper surface nozzle to the upper limit position of the car wash machine. Car washing can be performed without separating the upper surface nozzle and the car body more than necessary. And the upper surface drying nozzle can be sufficiently applied to the vehicle body to perform car washing with high washing and drying effects.

Further, even when the detection of the vehicle body becomes abnormal, the upper surface nozzle can be lifted and lowered in accordance with the set upper limit position without raising the upper nozzle to the upper limit position above the car washer. In this way, highly effective car washing can be performed.
