Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is provided with a car-washing machine such as a brush, a sprinkling nozzle, and a blower in a car-washing machine body formed in a gate shape. On the other hand, the present invention relates to a car wash machine that sequentially performs processes such as cleaning and drying.

[0002]

2. Description of the Related Art In a car wash machine of this type, a car wash processing device such as a brush, a water spray nozzle, and a blower is controlled according to the shape of an automobile body to be washed. Therefore, it is necessary to detect the shape of the car body.

As an example of means for detecting the shape of the automobile body, an ultrasonic sensor is provided above the car wash machine, the time required for transmitting an ultrasonic signal downward and receiving the reflected wave from the automobile body. A method of measuring the vehicle height of an automobile and detecting the vehicle shape is known. Further, as a car wash method using this car height data, for example, when the car height of a wagon car is detected, the car wash machine cannot move the car body because the upward movement of the upper surface cleaning brush cannot follow the steep inclination of the front part of the wagon car. In order to avoid the risk of damage, the upper surface cleaning brush is raised to avoid contact between the front part of the vehicle body and the upper surface cleaning brush.

However, since this vehicle shape detection method merely measures the height of the vehicle body, it can only roughly determine the vehicle type such as an ordinary passenger car having a low vehicle height and a wagon vehicle having a high vehicle height. Therefore, for example, even if it is attempted to control the upper surface cleaning brush according to the shape of the vehicle, it is not possible to perform fine control corresponding to automobiles of various shapes.

In order to solve such a problem, for example, a large number of photoelectric switches are provided in a vertical direction on a side of a car-washing machine main body formed in a gate shape, the side facing the car, so that the car-washing machine or the car can run. There is known a method in which the vehicle height is sequentially measured at a fixed distance cycle, vehicle height data corresponding to the traveling position of the car wash machine or the vehicle is stored in a storage device, and the vehicle shape is detected. Further, as a car washing method using this vehicle height data, for example, a method is known in which the upper surface cleaning brush is configured to be held up and down at an arbitrary height, and the upper surface cleaning brush is controlled to move up and down by following the vehicle height data. .

[0006]

However, in this method, in order to obtain accurate vehicle height data, it is necessary to provide a large number of photoelectric switches. Further, in order to store a large number of vehicle height data measured in a constant distance cycle, a storage device having a large capacity is required. In addition, a complicated device is required to hold the upper surface cleaning brush up and down at an arbitrary height.

[0007]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a car-washing machine main body formed in a gate shape.
Equipped with car wash treatment equipment such as brush, water spray nozzle, blower,
In a car wash machine that performs processing such as washing and drying of a car body as the car wash machine or the car runs, a vehicle height detection means for detecting a specific vehicle height and a travel position for detecting the running position of the car wash or car A detection means is provided, and the vehicle shape is determined by calculating the inclination angle of the upper surface of the vehicle body from the detected vehicle height and traveling position. Further, the car wash processing device such as the upper surface cleaning brush is controlled based on the car shape data.

[0008]

As a result, the vehicle shape can be detected without using a large number of photoelectric switches and without using a large-capacity storage device that stores a large amount of vehicle height data. In addition, since various car shapes can be distinguished, even if the car shape of the car that has been left behind by avoiding the cleaning brush is reduced, the car wash processing can be performed without complicating the structure of the car wash processing device. It can be carried out.

It is explanatory drawing which shows the method of detecting the front part shape of the vehicle body to wash. FIG. 5 shows a case where the automobile is a passenger car having a hood, and FIG. 6 shows a case where the automobile is a wagon without a hood.

As shown in FIG. 5A, when the car wash main body 1 is at the car wash start position, the car A stops at a predetermined stop position. When the car wash is started and the car wash main body 1 reaches the position shown in FIG. 5B, the photoelectric switch for detecting the lower part of the vehicle shields the light from the projector 14a and the light receiver 14b by the vehicle body to detect the vehicle body. The car wash machine stores the position Y1 of the car wash machine body 1 at this time in the memory 26. Car wash progresses,
When the car wash machine body 1 reaches the position shown in FIG. 5 (c),
Photoelectric switches 15a, 15 for detecting the roof position of a standard car

The inclination angle θ1 indicating the shape of the front part of the vehicle body is obtained from the calculation formula shown in Formula 1.

[0020]

[Equation 1]

When the angle θ1 is smaller than the predetermined angle, the car washing machine determines that the car A is a passenger car having a hood part. The same applies to the case of the wagon vehicle shown in FIG. 6, and when the obtained angle θ1 is larger than the predetermined angle, the car wash machine determines that the automobile A is the wagon vehicle. The angle serving as a reference for determining the magnitude of the angle θ1 is appropriately determined based on the shape of a general vehicle body.

A method of controlling the upper surface cleaning brush will be described as an example of controlling the car wash processing apparatus using the above results. When the vehicle is a passenger car having a hood, the upper surface cleaning brush 8 of the car washing machine runs along the vehicle body. It is determined that the vehicle A can be moved up and down, and the automobile A is washed without performing the avoidance operation of the upper surface washing brush 8. Further, when the car is a wagon, it is determined that if the car wash machine moves the upper surface cleaning brush 8 up and down along the vehicle body, the upper surface cleaning brush 8 cannot follow the inclination of the vehicle body and may damage the vehicle body. Then, the air cylinder 21 for raising and lowering the upper surface cleaning brush is operated to raise the upper surface cleaning brush 8 to avoid contact between the upper surface cleaning brush 8 and the front part of the vehicle body and clean the automobile A.

FIGS. 7 and 8 are explanatory views showing a method of detecting the rear shape of an automobile body to be washed and a method of washing a car according to the detected shape by the method of detecting the shape of a vehicle according to the present invention. FIG. 7 shows a case where the automobile is a passenger car having a trunk portion, and FIG. 8 shows a case where the automobile is a van type vehicle having no trunk portion.

When the car wash machine reaches the position shown in FIG. 7 (a) during the car wash, the photoelectric switch for detecting the roof position of the ordinary car releases the light blocking by the vehicle body between the projector 15a and the receiver 15b. The car body will no longer be detected. The car wash machine stores the position Y3 of the car wash machine body 1 at this time in the memory 26. When the car wash progresses and the car wash reaches the position shown in FIG. 7B, the photoelectric switches 14a and 14b for detecting the lower part of the vehicle no longer detect the vehicle body. The car wash machine stores the position Y4 of the car wash machine body 1 at this time.

At this time, from the distance ha between the height h1 of the photoelectric switches 14a and 14b and the height h2 of the photoelectric switches 15a and 15b and the distance Lb between the positions Y3 and Y4, the inclination angle indicating the shape of the rear part of the vehicle body is obtained. θ2 is obtained by the calculation formula shown in Equation 2.

[0026]

[Equation 2]

When the angle θ2 is smaller than the predetermined angle, the car washing machine determines that the car A is a passenger car having a trunk. The same applies to the case of the van type vehicle shown in FIG. 8. When the obtained angle θ2 is larger than the predetermined angle, the car wash machine determines that the automobile A is a van type vehicle having no trunk portion. The angle that serves as a reference for determining the magnitude of the angle θ2 is appropriately determined based on the shape of a general vehicle body.

When the automobile A is a passenger car having a trunk portion, the upper surface cleaning brush 8 can be moved up and down along the automobile body to be washed in the returning process, as shown in FIG.
As shown in FIG. 3, the car wash machine lowers the upper surface cleaning brush 8 to wash the car while keeping it along the vehicle body. When the automobile A is a van type car having no trunk portion, the upper surface cleaning brush 8 can be moved up and down along the vehicle body in the returning process, but when the car wash machine travels at high speed, Since the upper surface cleaning brush 8 may not follow the inclination of the vehicle body and may damage the vehicle body, the vehicle washing machine reduces the traveling speed during the specific section R at the rear portion of the vehicle body as shown in FIG. 8C. The upper surface cleaning brush 8 is allowed to move up and down while following the inclination of the vehicle body.

As shown in FIG. 9, in the case of an automobile in which the inclination angle θ2 of the rear portion of the vehicle body is steeper, the upper surface cleaning brush 8 can be moved up and down along the vehicle body to wash the vehicle in the returning process. Therefore, as shown in FIG. 9 (a) or FIG. 9 (b), the car washing machine raises the upper surface cleaning brush 8 at the rear part of the vehicle body to avoid contact between the rear part of the vehicle body and the upper surface cleaning brush to carry out the car washing. .

FIGS. 10 and 11 show a vehicle body to be washed, which is a wagon vehicle with a steep slope in the front part of the vehicle body or a wagon car with a gentle slope in the front part according to the method for detecting the shape of a vehicle according to the present invention. It is explanatory drawing which shows the method of detecting whether there exists, and the method of performing a car wash according to the detected shape. FIG. 10 shows a case where the vehicle is a wagon vehicle with a steep front slope.
1 shows the case of a wagon vehicle with a gentle inclination at the front of the vehicle body.

When the car wash machine reaches the position shown in FIG. 10 (a) during car washing, the photoelectric switch for detecting the normal car roof position is shielded by the vehicle body between the projector 15a and the light receiver 15b to detect the vehicle body. To do. The car wash machine stores the position Y5 of the car wash machine body 1 at this time in the memory 26. When the car wash progresses and the car wash machine body 1 reaches the position shown in FIG. 10B, the photoelectric switch 16 for detecting the position of the wagon car roof.
a and 16b detect the vehicle body. The car wash machine stores the position Y6 of the car wash machine body 1 at this time.

At this time, the distance hc between the height h2 of the photoelectric switches 15a and 15b and the height h3 of the photoelectric switches 16a and 16b and the distance Lc between the position Y5 and the position Y6 are used to indicate the shape of the front portion of the vehicle body. The angle θ3 is obtained by the calculation formula shown in Formula 3.

[0033]

[Equation 3]

When the angle θ3 is larger than the predetermined angle, the car wash machine determines that the car A is a wagon with a steep front slope. The same applies to the case of a wagon vehicle with a gentle slope in the front part of the vehicle shown in FIG. 11, and when the obtained angle θ3 is smaller than a predetermined angle, the car washer is such that the car A has a gentle slope in the front part of the vehicle. Judge that it is a wagon car. The angle that serves as a reference for determining the magnitude of the angle θ3 is appropriately determined based on the shape of a general vehicle body.

In the case of a wagon vehicle with a steep front slope, the car washing machine judges that the upper surface cleaning brush 8 cannot move upward along the front slope of the car body and may damage the car body. Then, as shown in FIG. 10 (c), the air cylinder 21 for lifting the upper surface cleaning brush is operated to raise the upper surface cleaning brush 8 to wash the car while avoiding contact between the front part of the vehicle body and the upper surface cleaning brush 8. . Further, in the case of a wagon vehicle with a gentle inclination in the front part of the vehicle body, the car washing machine judges that the upper surface cleaning brush 8 can move upward along the inclination of the front surface of the vehicle body, and the result is shown in FIG. As described above, the operation of the air cylinder 21 for lifting the upper surface cleaning brush is released, the upper surface cleaning brush 8 is lowered, and the front part of the vehicle body and the upper surface cleaning brush 8 are brought into contact with each other to wash the car.

As shown in FIG. 12, the photoelectric switches 14a and 14b for detecting the lower portion of the vehicle detect the vehicle body and the photoelectric switch 15 for detecting the normal vehicle roof position.
The angle θ obtained from the position where a and 15b detect the vehicle body
1 is smaller than a predetermined value, and the photoelectric switches 15a and 15b for detecting the vehicle roof position detect the vehicle body and the photoelectric switch 16 for detecting the wagon vehicle roof position.
a, 16b is the angle θ obtained from the position where the vehicle body is detected.
When 3 is also smaller than the predetermined value, the car washing machine determines that the upper surface cleaning brush can move upward along the inclined surface of the front part of the wagon, and carries out the car cleaning by bringing the front part of the vehicle body and the upper surface cleaning brush into contact with each other.

In FIG. 13, the vehicle shape detection method according to the present invention detects that the vehicle to be washed is a wagon vehicle, and the height of the roof position of the vehicle for detecting the vehicle is detected at the front of the vehicle. FIG. 9 is an explanatory diagram showing a car wash operation when the shape is not detected in the rear portion.

In a car wash of a wagon, if an attempt is made to clean the inclined surface of the rear surface of the vehicle body with the upper surface cleaning brush, the upper surface cleaning brush falls from a considerable height, and the upper surface cleaning brush recoils and collides with the rear surface of the vehicle body. Since there is a risk of it coming up, raise the upper surface cleaning brush at the rear end of the car roof,
Avoiding contact with the car body. However, depending on the shape of the vehicle body, there is an automobile that detects the height of the wagon vehicle at the front portion of the vehicle body and does not detect the height of the wagon vehicle at the rear portion of the vehicle body. At this time, the car washer detects the roof position of the wagon at a position considerably forward of the rear end of the car roof, and at that point, if it is judged as the rear end of the roof and the upper surface cleaning brush is lifted, unwashed residue may occur. Becomes

FIG. 13A shows a typical car wash of a wagon.
At the position Y7 shown in (1), the photoelectric switch for detecting the roof position of the wagon is released from the light blocking by the vehicle body between the projector 16a and the light receiver 16b, and the vehicle body is no longer detected. The car washer stores position Y7 in memory 26.

At this time, the inclination angle .theta.4 for judging that the vehicle is a wagon and the interval hc between the height h1 of the photoelectric switches 14a and 14b and the height h3 of the photoelectric switches 16a and 16b.
And the position Y7, the position Y8 of the rear part of the vehicle body is obtained by the calculation formula shown in Formula 4.

[0041]

[Equation 4]

When the photoelectric switches 14a and 14b for detecting the lower part of the vehicle body before the position of Y8 stop detecting the vehicle body, it is determined that the car wash machine is a normal wagon vehicle, and the upper surface cleaning brush 8 reaches the position Y7. At this time, the air cylinder 21 for raising and lowering the upper surface cleaning brush is operated to avoid contact between the rear portion of the vehicle body and the upper surface cleaning brush 8 to wash the car. The angle θ4, which is a reference for determining that the vehicle is a wagon vehicle, is appropriately determined based on the shape of a general vehicle body.

As shown in FIG. 13B, the height of the roof position of the wagon vehicle for detecting that it is a wagon vehicle is detected at the front portion of the wagon vehicle and not at the rear portion of the wagon vehicle. At the position Y8 obtained in the same manner,
Photoelectric switches 14a and 14b for detecting the lower part of the vehicle body detect the vehicle body. In this case, the upper surface cleaning brush 8 is at the position 7
When the upper surface cleaning brush 8 is lifted when reaching, the unwashed residue occurs. Therefore, the car washing machine determines that it is necessary to correct the position of the rear end portion of the roof of the car, and FIG.
As shown in, the photoelectric switch 14 for detecting the lower part of the vehicle body
When the upper surface cleaning brush 8 reaches that position, the air cylinder 21 for moving the upper surface cleaning brush is operated by setting the rear end of the roof at a position separated by a predetermined distance B from the position Y9 where a and 14b no longer detect the vehicle body. Then, the upper surface cleaning brush 8 is raised. As a result, the upper surface cleaning brush 8 can be brought into contact with the rear end of the roof for cleaning, so that the uncleaned portion can be prevented.

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, as shown in FIG. 14, a photoelectric switch 1 for detecting the roof position of an ordinary vehicle
5a and 15b and photoelectric switches 16a and 16b for detecting the roof position of the wagon vehicle, photoelectric switches 28a and 2b
By adding 8b, it is possible to detect the tilt angle of the windshield one step more finely. Thus, for example, if the car to be washed is a jeep type car,
You can avoid the top brush and wash in the windshield with a steep slope.

When the car wash machine reaches the position shown in FIG. 14A during the car wash, the added photoelectric switch blocks the space between the projector 28a and the photoreceiver 28b (not shown) by the vehicle body to detect the vehicle body. The car wash machine stores the position Y10 at this time in the memory 26. As the car wash progresses, photoelectric switches 16a and 16b for detecting the roof position of the wagon detect the vehicle body. The car wash machine stores the position Y11 at this time in the memory 26.

At this time, the distance hd between the photoelectric switches 16a and 16b and the photoelectric switch 28, and the positions Y10 and Y
From the distance Le with 11, the inclination angle θ of the windshield
5 is obtained by the calculation formula shown in Formula 5.

[0047]

[Equation 5]

When this angle θ5 is larger than a predetermined angle, it is determined that the car washer is a jeep type car having a steep windshield. The angle serving as a reference for determining the magnitude of the angle θ5 is appropriately determined based on the shape of a general vehicle body.

When it is determined that the vehicle is a jeep type vehicle, FIG.
As shown in (c), the car washing machine determines that the upper surface cleaning brush 8 cannot move upward along the inclination of the windshield portion, and raises the upper surface cleaning brush 8 to wash the front glass portion and the upper surface. Car wash is performed by avoiding contact with the brush 8.

In the car washing method of the embodiment, the control of the upper surface cleaning brush has been described, but the upper surface drying nozzle and other car wash processing devices are also controlled based on the vehicle shape data detected by the vehicle shape detecting method of the present invention. it can.

[0051]

As described above, the present invention is provided with a car wash processing device such as a brush, a sprinkling nozzle, and a blower in a car-washing machine body formed in a gate shape. In a car wash machine that performs processing such as washing and drying the vehicle body, vehicle height detection means for detecting a specific vehicle height and traveling position detection means for detecting the traveling position of the car wash body or the vehicle are provided, and the detected vehicle height The vehicle shape is determined by calculating the inclination angle of the upper surface of the vehicle body from the traveling position, and the car wash device is controlled according to the detected vehicle shape.

Thus, the vehicle shape can be detected without using a large number of photoelectric switches and without using a large amount of storage device for storing vehicle height data. Also,
Since various car shapes can be discriminated, it is possible to carry out car washing with a small amount of unwashed residue even in the case of a car shape that has been left unwashed by avoiding the washing brush in the past.
