As the supporting and operating mechanisms for the upper surface and the pair of side rotating brushes 4 and 5, 5 are conventionally known mechanisms, detailed explanations will be omitted.

The front part of the gate-shaped traveling frame 1 is equipped with a drying device, that is, on both sides of the concave traveling frame 1, there are a pair of side blowing nozzles 21. 21 is provided, and an upper surface blowing nozzle 22 as a processing device, which also opens inward on the upper surface thereof, is pivoted so as to be able to rise and fall via a parallel link mechanism 24, and the parallel link mechanism 24 is Rotation control is performed in the vertical direction around the pivot points 25 and 26 by the expansion and contraction of the lifting cylinder 27. These side and top blower nozzles 21, 21 and 22 are communicated with blowers 23 installed at the lower ends of both sides of the portal traveling frame 1. Since this drying device is also of a conventionally known structure, detailed explanation thereof will be omitted.

A rinsing water injection device R as a processing device is provided outside the side rotating brush 5°5 of the gate-shaped traveling frame l, and is capable of injecting rinsing water onto the vehicle body surface of the vehicle. The structure of R will be explained mainly with reference to FIG. The rinsing water injection pipe 31 is provided with a plurality of nozzles 32 spaced apart from each other with their nozzles facing inward of the gate-shaped traveling frame 1. A rinsing water supply pipe 34 is connected to the middle of the rinsing water injection pipe 31 via a solenoid valve 33, and this rinsing water supply pipe 34 is connected to a water pump P supported by the concave traveling frame 1, Clean water can be injected from the nozzle 32 by opening the valve 3°3.

Further, the support frame 28 is provided with a wax coating device W as a processing device inside the rinsing water injection device R. This wax application device W includes a concave water-based wax injection pipe 3 disposed substantially parallel to the rinsing water injection pipe 31.
7, and the aqueous wax injection pipe 37 is provided with a plurality of nozzles 38 at intervals, the nozzles facing inward of the gate-shaped traveling frame 1. A water-based wax supply pipe 39 is connected in the middle of the water-based wax injection pipe 37, and this supply pipe 39 is connected to a water supply pipe 42 via an ejector 40 and a solenoid valve 41. It is connected to the. A wax stock solution supply pipe 43 connected to the wax tank T is connected to the ejector 40.

Therefore, when the solenoid valve 41 is opened after the water pump P is driven, the pressure water reaches the ejector 40, where the ejector effect sucks the aqueous Wax stock solution from the wax stock solution supply pipe 43, and the water-based wax mixed with water is extracted. Multiple nozzles 3

The cleaning water injection pipe 45 is connected to a water supply pipe 47 connected to a water supply source S such as a tap, and a solenoid valve 48 is inserted in the middle of the water supply pipe 47, and when the solenoid valve 48 opens, the nozzle 46 More cleaning water is sprayed.

Further, above the front part of the gate-shaped traveling frame 1, there is a detection device of the present invention that detects the body position and vehicle height of the vehicle to be washed or polished and sends the information to the car wash control circuit 59 as a control means. The configuration of this detection device A will be described below with reference to FIG. 4.5.

At the front upper part of the gate-shaped traveling frame l, there is a transmitting section 52 that receives pulsed ultrasonic waves transmitted from a transmitting circuit 51 and emits them toward the upper surface of the vehicle body, and a transmitting section 52 that receives reflected waves from the vehicle body surface. A receiving section 53 is provided close to each other, and the reflected ultrasound received by the receiving section 53 is sent to a receiving circuit 54.
Then, it is determined whether the reflected ultrasonic wave was emitted from the transmitter 52 or not, and if it is the ultrasonic wave emitted from the transmitter 52, it is sent to the arithmetic circuit 55. Arithmetic circuit 55
When the transmitting circuit 51 transmits an ultrasonic wave, the ultrasonic wave is received at the same time, and due to the difference in reception time between the ultrasonic wave from the transmitting circuit 51 and the reflected ultrasonic wave from the receiving circuit 54, the ultrasonic wave is transmitted from the transmitting section 52 or the receiving section 53 to the vehicle body. The distance to a reflector such as a surface is calculated, and voltage signals that increase in proportion to the distance are sent to the first to third comparison circuits 56, 57, and 58. The transmitter 52, the receiver 53, the transmitter circuit 51, the receiver circuit 54, and the arithmetic circuit 55 cooperate with each other to configure the reflection-type ultrasonic detection device 50.

Each of the comparison circuits 56, 57, and 58 is connected to the ultrasonic detection device 5.
The voltage signal output from the arithmetic circuit 55 of 0 is compared with a plurality of reference voltages corresponding to predetermined distances, and when the voltage signal is less than the reference voltage, an output signal is sent to a car wash control circuit 59 to be described later. For example, the first comparator circuit 56 sends the voltage signal from the arithmetic circuit 55 at a certain low height from the ground (the first 3 reherto)
The second comparison circuit 57 generates an output signal when the voltage signal from the arithmetic circuit 55 is smaller than the first reference voltage E corresponding to Second reference voltage E corresponding to high (second level H,)
2 or less, an output signal is generated, and the third comparison circuit 58
, the voltage signal from the arithmetic circuit 55 corresponds to the maximum vehicle height of a relatively high vehicle such as a pan-type vehicle (third level (3)).
The third reference voltage E corresponding to the third reference voltage E is configured to generate the following horn signals. The detection device A outputs an output signal from the first comparison circuit 56 when a vehicle, such as an ordinary passenger car, whose vehicle height is greater than H3 and smaller than Ht enters the gate-shaped traveling frame 1. When a vehicle such as a pan-shaped vehicle whose vehicle height is thicker than H2 or smaller than H2 enters the concave traveling frame 1, the first
．． Simultaneously output signals from the second comparison circuits 56 and 57,
Furthermore, when a vehicle with a vehicle height exceeding H3 enters the concave traveling frame 1 and it is determined that the vehicle and the frame 1 are in a relative positional relationship inappropriate for car washing, the first, second . The third comparison circuits 56, 57, and 58 are all configured to simultaneously issue output signals.

As shown in FIG. 4, the transmitter 52 of the ultrasonic detection device 50
Since the receiving part 53 is formed in a conical shape, when washing the car, washing water is scattered by the rotation of the top and side rotating brushes 4.5.5 and adheres to the inner surfaces of the conical transmitting part 52 and the receiving part 53. However, there is a habit that the ultrasonic waves emitted from the transmitting section 52 directly enter the receiving section 53, causing malfunction.
In addition, weak ultrasonic waves called side lobes are generated along the conical side wall of the transmitter 52, but the propagation direction and intensity of these side lobes change depending on the temperature, density, etc. of the atmosphere, so it depends on the atmospheric conditions. In this case, the receiving section 53 may receive a reflected wave from an object located laterally instead of a reflected wave from a reflector directly below it, causing a malfunction.

Therefore, at the tips of the transmitting section 52 and the receiving section 53, there is a
Synthetic resin shielding tubes 52a and 53a extending linearly and thinly along the line and having open bottom ends are integrally connected to each other, and these shielding tubes 52a and 53a prevent splashes of washing water and the like during car washing. In addition to effectively preventing the ultrasonic waves from entering the receiving sections 52 and 53, the side lobes of the ultrasonic waves described above can be shielded. If a constant gap 50s is set between the lower ends of the openings of the shielding bearing tubes 52a and 53a as shown in the illustrated example, and a discontinuous portion is formed between the lower ends of the openings, the shielding of the side lobe can be prevented. The effect can be obtained even more reliably.

Additionally, when a car wash is operated in cold weather, the temperature of the washing water is higher than the outside air, which increases the temperature and humidity of the air inside the car wash, resulting in cold air.

Condensation forms on the receiving sections 52 and 53 and water droplets adhere to their inner surfaces, causing failures and malfunctions.

Since the tip of the receiving section 52.53 is covered with the shielding tubes 52a, 53a, the convection of air inside and outside the shielding tubes 52a, 53a can be suppressed. It is possible to prevent the occurrence of dew condensation.

In FIG. 1, a control panel 61 attached to the front side of one side of the gate-shaped traveling frame includes a car wash method selection switch 62 for selecting a predetermined car wash program, and a driving motor of the car wash device (see FIG. A start button 63 for starting the car wash method selection switch 62 (not shown) is provided in the control panel 61.
Further, the car wash control circuit 59 (FIG. 5) as a control means is built in, which receives an output signal from the reflection type ultrasonic detection device 50 and operates the car wash device according to a predetermined control program.

The car wash control circuit 59 consists of a first control program for washing and drying the car body and a second control program for waxing, rinsing and drying the car body, and when the first control program is selected, the gate type traveling frame 1, when the cleaning water injection device C is activated and the cleaning water injection pipe 45
Washing water is sprayed from the top and side rotating brushes 4 and 5.
．． Wash the car body surface while brushing with step 5,
Also, when the gate-type traveling frame 1 goes back, the drying device is activated to dry the wet car body surface after washing with the pressure air jetted from the top and side blowing nozzles 22, 21, while the second control program When selected, when the gate-shaped traveling frame 1 moves back and forth, the wax application device W and the rinsing water injection device R are operated to spray clean water from the aqueous wax injection pipe 37 to wash away excess wax, and the gate-shaped traveling frame 1 is moved back and forth. When the traveling frame 1 returns, a drying device is operated to dry the surface of the vehicle body after wax application and rinsing.

Next, the operation of the device of the present invention will be explained with reference to FIG. Second
Which of the control programs is on the other hand, for example the first! IJff
When the start button 63 is pressed after selecting the l program, a driving engine (not shown) is started, and the gate-shaped traveling frame 1 starts moving toward the vehicle (2). When the reflection type ultrasonic detection device 50 reaches directly above the front end of the vehicle (2),
As shown in FIG. 3(a), a reflection type ultrasonic detection device 50
detects that the vehicle body has entered the gate-type traveling frame 1, that is, that the vehicle height is greater than the first rubel H, and sends an output signal from the first comparison circuit 56 to the car wash control circuit 59. The prime mover 8° 19 is operated to rotate the top and side rotating brushes 4° 5.5, and the solenoid valve 48 of the cleaning water injection device C is opened to inject cleaning water from the nozzle 46 of the cleaning water injection pipe 45. let The gate-shaped traveling frame 1 moves further forward, and the reflection-type ultrasonic detection device 50
When reaches the upper front surface of the vehicle (Fig. 3 (b)), when the vehicle height is relatively low like a normal passenger car and is between the first level H and the second level H1. , the reflection type ultrasonic detection device 11!50 detects this and sends a signal from the first comparison circuit 56 to the car wash control circuit 59, and the car wash control circuit 59 operates to extend the air cylinder 14 and rotate the top surface. The brush 4 is lowered from the upper limit position (shown by the chain line in Figure 3) to the lower limit position (shown by the dotted line in Figure 3), and if the vehicle height is between the second level H2 and the third level H1, such as in a pan-type car, etc. In some cases, the reflective ultrasonic detection device 50 detects this and selects the first. A signal is sent from the second comparison circuit 56, 57 to the car wash control circuit 59, and the air cylinder 14 is contracted to hold the upper rotating brush 4 at the upper limit position.

Furthermore, if the vehicle height exceeds the third level H3,
Since it is determined that the vehicle and the portal traveling frame 1 are in a relative positional relationship inappropriate for car washing, the car wash control circuit 59
~Receiving output signals from the third comparison circuits 56 to 58, the driving prime mover (not shown) is deactivated to stop the traveling of the gate-shaped traveling frame 1, and each rotating brush 4 of the car washing device is
．． Emergency stop the operation of all processing equipment including 5. This prevents a collision between the vehicle and the gate-shaped traveling frame 1, etc., and also prevents each rotating brush 4.5 from continuing to rub a specific surface of the vehicle more than necessary and damaging it.

In the above, if the vehicle height is below the third level H8,
The traveling prime mover is continuously operated by the car wash control circuit 59 to keep the portal traveling frame 1 running, and the vehicle height is set to the second level.
For vehicles such as passenger cars that are lower than level H2 (shown by the solid line in Figure 3), the upper rotary brush 4 performs cleaning while brushing along the upper surface shape of the vehicle, while the vehicle height is at the second level. Vehicles such as pan-shaped cars that are higher than H, (
3), the upper rotating brush 4 is held at the upper limit position while brushing the upper surface of the vehicle body, and at the same time, the side rotating brushes 5 are opened and closed laterally. Move along the front, sides, and rear of the vehicle, brushing and cleaning these surfaces. When the reflection type ultrasonic detection device 5o passes the rear end of the vehicle body (Fig. 3 (c)
), the reflection type ultrasonic detection device 50 detects that the vehicle height has become lower than the first level H1 and activates a timer (not shown). After passing through the rear end, the electromagnetic valve 48 is closed to stop the injection of cleaning water from the nozzle 46 of the cleaning water injection pipe 45, and the driving force a (not shown) for driving and the brush driving The prime movers 8, 19 are deactivated to stop the concave traveling frame 1 from traveling, and at the same time, the rotation of the top rotating brush 4 and the side rotating brushes 5, 5 is stopped.

Next, the drying process begins, and the concave traveling frame 1 starts going back with the upper rotating brush 4 raised to the upper limit position, and when the rear of the vehicle (2) enters the concave traveling frame 1, reflected ultrasonic detection is performed. The device 50 detects that the height of the vehicle is at the second level H.
2 is detected, an output signal is sent from the first comparison circuit 56 to the car wash control circuit 59 to drive the blower 23.

At the same time, the vehicle height is set to the second level H2 and the second level H2.
, an output signal is sent from the first comparison circuit 56 to the car wash control circuit 59, so that the lifting cylinder 27 is extended and the upper air blowing nozzle 22 is once lowered to the lower limit position. While moving up and down along the top of the vehicle,
Furthermore, if the vehicle height is greater than the second level H2, the first
．． By sending output signals from the second comparison circuits 56 and 57 to the car wash control circuit 59, the upper air blower nozzle 22 and the side air blower are operated as the portal traveling frame l goes back, with the upper air blower nozzle 22 held at the upper limit position. When the 6-concave traveling frame 1, which blows pressurized air from the nozzle 21 onto the top and side surfaces of the vehicle body to efficiently dry the surface of the vehicle body, continues its go-around and leaves the front end of the vehicle (Fig. 3 (a)), Car wash control circuit 5 based on detection by reflection type ultrasonic detection device 50
9, the blower 23 and the driving motor (not shown) are deactivated, the air blowing from the blower nozzles 21, 22, and 22 is stopped, and the traveling of the gate-shaped traveling frame 1 is stopped, thereby completing the drying process.

Further, when the second control program is selected, as in the case where a water-based wax is applied to a vehicle that has already been washed and then dried, the operation of the car wash apparatus is controlled as follows. That is, when the start button 54 is pressed, the recessed traveling frame 1 starts moving toward the vehicle (2), and at this time, the upper rotating brush 4 is held at the upper limit position, and the prime mover 8.19 for rotating the brush is also disabled. kept in working condition.

When the reflection-type ultrasonic detection device 50 reaches directly above the front end of the vehicle (2) due to the advancement of the concave traveling frame 1, the reflection-type ultrasonic detection device 50 detects this and activates a timer (not shown) for a certain period of time. After the elapsed time, when the water-based wax injection pipe 37 and the rinsing water injection pipe 31 reach the front of the vehicle body, the solenoid valves 33 and 41 are opened by the timer, and the water-based wax is sprayed from the nozzle 38 of the water-based wax injection pipe 37 onto the vehicle body surface. After spraying clean water onto the car surface from the nozzle 32 of the rinse water injection pipe 31 to wash away excess wax liquid, when the reflective ultrasonic detection device 50 passes directly above the rear end of the car body. The reflection type ultrasonic detection device 50 detects this and activates a timer (not shown), which closes the solenoid valve 33.41 when the water-based wax injection pipe 39 and the rinsing water injection pipe 31 pass the rear of the vehicle body. The valve is turned on to stop the injection of aqueous wax and rinsing water, and at the same time, the operation of a traveling prime mover (not shown) is stopped to stop the gate-shaped traveling frame 1 from moving back and forth. Then, when the drying process begins and the gate-shaped traveling frame 1 starts going back, if the reflective ultrasonic detection device 50 detects that the vehicle height is higher than the second level H2 during the going out, The upper surface blower nozzle 22 is held at the upper limit position, and if it is detected that the vehicle height is between the second level H2 and the second level H2, the upper surface blower nozzle 22 is moved by the extension operation of the lifting cylinder 27. is lowered and raised and lowered along the top surface of the vehicle body. When the reflective ultrasonic detection bag ff50 detects the rear end of the vehicle body due to the return movement of the gate-type traveling frame l, the blower 23 is driven and pressurized air is sent from the top blow nozzle 22 and the side blow nozzles 21, 21 to the top surface of the car body and It is sprayed onto the sides and efficiently dries these surfaces. When the gate-shaped traveling frame 1 moves away from the front end of the vehicle (2) during a go-around, both the blower 23 and the traveling prime mover (not shown) are deactivated based on the detection by the reflection type ultrasonic detection device 50. The air blowing from the upper and side air blowing nozzles 22.degree. 21.21 is stopped, and the traveling of the gate-shaped traveling frame 1 is also stopped, thereby completing the drying process.

C1 Effects of the invention As described above, according to the present invention, there is provided a car washing apparatus which has a frame equipped with a rotating brush capable of brushing a vehicle, and which allows the frame and the vehicle to move relative to each other in the longitudinal direction thereof. A detection device capable of detecting that the vehicle and the frame are in a relative positional relationship inappropriate for car washing, and a control means for stopping the relative movement and the operation of the rotating brush in response to a detection signal output by the detection device. Therefore, when the frame and the vehicle are moved relative to each other while operating the rotating brush to wash the vehicle, if the detection device detects that the relative positional relationship between the two is inappropriate for washing the vehicle, the detection device will respond accordingly. The above-mentioned relative interlocking and the operation of the rotating brush can be automatically stopped, and therefore, collision and damage between the vehicle and the frame etc. due to the continuation of the relative movement can be prevented. Moreover, since the rotating brush is not left in operation in the state where the relative movement is stopped, there is no risk of the rotating brush scratching a particular surface of the vehicle by excessively scratching it.
