[0002]

2. Description of the Related Art In a car washer equipped with a car wash processing device such as a washing brush and a drying nozzle in a car wash machine main body to relatively move the car wash machine body and the car body to be washed to wash the car body, the car wash machine to be washed is used. Depending on the shape of the cleaning brush,
It controls the car wash processing equipment such as the drying nozzle. Therefore, it is necessary to detect the shape of the vehicle body.

[0003] The present applicant has disclosed in Japanese Patent Application Laid-Open No. 10-3381.
No. 03 discloses a “vehicle shape detecting device and a car washer equipped with the device”. According to the proposal, a plurality of vehicle body detection means are provided on the side of the car wash machine body, and the body data detected by relatively moving the car wash machine body and the car body are stored as a binary image, and the car body contour is obtained by image processing. And protrusions are detected. This makes it possible to reliably detect a projection such as a front mirror or a rear mirror projecting through the thin arm without overlooking the projection, and to avoid the vicinity of the projection to allow the cleaning brush to operate.

[0004]

The shape of the vehicle body including the protrusions detected by the above method is a contour projected from the side of the vehicle body, and the upper surface cleaning brush for brushing the upper surface of the vehicle body is controlled in the vertical direction. Can be enough data to do so. However, since this data is only two-dimensional data of the vehicle body viewed from the side and does not include the shape in the vehicle width direction, even if it is recognized that there is a protrusion, the protrusion is located at the center of the vehicle body. I couldn't tell if it was, or it was closer to the left or right. Therefore, it was not enough data to control the side cleaning brush for brushing the front and rear sides of the vehicle body.
Therefore, in the past, an ultrasonic sensor or proximity switch was used to control the side cleaning brush, and when there was a protrusion in the contour of the vehicle body viewed from the side, the side cleaning brush was avoided in the vicinity of the protrusion. Was. For this reason, for example, when the rear mirror is located on the right side of the rear surface of the one-box car, the entire rear surface is avoided, and there is a problem that the left side of the rear surface is left unwashed even though brushing is possible.

Is loading.

Next, the operation of the first vehicle body detecting means of the embodiment of the present invention will be described with reference to FIG. As shown in FIG. 5A, when the car washer body 1 is at the car wash start position, the car A is stopped at a predetermined stop position. When the car wash is started, the car wash machine sequentially turns on and off the unit light-emitting elements constituting the light projector 14, and detects light reception and non-light reception by the light receiver 15 to detect the body of the automobile A. Fig. 5
When the light reaches the position shown in (b), the light of the unit light-emitting elements constituting the light-emitter 14 located below ha is blocked by the body of the automobile A and is not received by the light-receiver 15. The presence or absence of light reception by the light receiver 15 at this time is stored in the first storage means as the detection state of the vehicle body at this position. When the car wash is performed and the car wash machine body 1 reaches the position shown in FIG.
Light located below b is blocked by the body of the automobile A and is not received by the light receiver 15. The presence or absence of light reception by the light receiver 15 at this time is also stored in the first storage means as the detection state of the vehicle body at this position. In this way, whether or not the light from the light projector 14 is blocked by the vehicle as the car washer body 1 travels is sequentially stored in the first storage means, and as shown in FIG. Detected as valued image data.

Next, the operation of the second vehicle body detecting means of the embodiment of the present invention will be described with reference to FIG. In the same manner as described above, the unit light-emitting elements constituting the light emitter 16 are sequentially turned on and off at the same time as the start of car washing, and the light receivers 17 and 18 detect light reception and non-light reception to detect the widthwise body of the automobile A. Until the optical axis formed by the light emitter and the light receiver reaches the tip of the automobile A, all of the optical axes A to D and A ′ to D ′ are in a light transmitting state. When 1 reaches the position shown in FIG. 6A, the light from the unit light emitting element is blocked by a custom mirror protruding from the vehicle body, and D,
A 'and B' are in the light-shielded state. At this time, the light receiver 17.1
The presence or absence of the light reception at 8 is stored in the second storage means as the detection state of the width of the vehicle body at this position. By the way,
In this case, since the blocked optical axes are D, A ', and B', it can be determined that there is a protrusion on the left end of the vehicle body. Strictly speaking, the first vehicle body detecting means executed in parallel detects the end of the automobile (the front end in this case), and the optical axes D, A ', and B' are blocked near the end. Therefore, it is determined that there is a protrusion to the left of the front end of the vehicle body. Next, when the car washer body 1 reaches the position shown in FIG. 6B, all the optical axes are blocked by the body roof.
When the position (c) is reached, the optical axes B, C and D 'are blocked by the rear mirror projecting from the rear end of the vehicle body, and are respectively stored in the second storage means as the vehicle body width direction detection state. In this way, whether or not the light from the light projector 16 is blocked by the automobile as the car washer body 1 travels is sequentially stored in the second storage means, and the presence / absence and existence position of the vehicle body and the protrusion are detected. . In addition, optical axes A to D,
Since the optical axes A ′ to D ′ intersect above the opening space of the car washer, when detecting the protrusion, it can be determined that there is a protrusion at the intersection of the light-shielded optical axis. It is possible to accurately detect the position of the protrusions (here, the custom mirror and the rear mirror) on the upper part of the vehicle body.

The size of a projection such as a mirror occupying the entire length of the vehicle body is small, and therefore most of the results detected by the second vehicle body detection means are occupied by the vehicle body. That is, in the state where the car body placed at an appropriate position with respect to the car washer is detected, the transmissive / shielded states of the optical axes A to D and A ′ to D ′ crossing each other appear symmetrically. The left and right optical axes are asymmetric only at the front end or rear end position of the vehicle body where there is a high possibility that the protrusion exists. From this, when the left and right optical axes are asymmetric for more than a predetermined time, it can be determined that the vehicle is stopped obliquely with respect to the car washer, or that the vehicle is stopped imbalanced left or right, In the present embodiment, the car wash operation is stopped as an abnormal stop position.

Next, the operation of the car washer according to the embodiment of the present invention will be described with reference to the flowchart of FIG. First, car wash machine 1
A car wash course is selected from an operation panel (not shown) (S1), and when a start key is pressed (S2), the motor 4 is actuated in response to the selection (S3), and the car wash machine travels along the rail 3 (step S3). Start. When the car washer starts running, the light-shielding detecting means and the second vehicle body detecting means are activated (S4), the outline including the projection when the automobile is viewed from the side, the presence or absence of the vehicle body when the automobile is viewed from above, and the position of the projection. Is detected (S
5). Subsequently, based on the detection result in S5, car wash control data for driving the car wash processing device such as the upper surface cleaning brush, the side cleaning brush, and the water spray nozzle is created and stored (S5).
6). Next, if there is no abnormality in the stop position of the car detected by the second car body detecting means (S7), the car wash processing device is driven according to the car wash control data stored in S6 to wash the car body (S8). . In a series of car washing operations in which the car washing machine reciprocates a plurality of times, the car washing is performed while detecting the vehicle shape until the car reaches the rear end of the car for the first time after the car washing machine starts running, that is, until the first process is completed. The processing device is controlled (S9), and after the first return step, the contents of the car wash course selected based on the car wash control data created and stored in S6 are executed. Note that the car wash control data created and stored in S6 includes positional information as to whether a protrusion exists on the right side or the left side of the vehicle body when the vehicle body has a protrusion. Therefore, for example, as shown in FIG. 6, if the rear mirror exists at the upper right of the rear end of the one-box car, fine control can be performed such that the side cleaning brush is applied only to the rear left half. By the way, if it is detected in S7 that the stop position of the car is abnormal, an error output notifying the stop position abnormality is made on the operation panel or the like of the car washer (S10), and the electric motor is stopped to stop the running of the car washer. (S11). When the operation of the car washer is reset by the operator who has confirmed that the error has occurred (S1).
2) Return the car washer to the start position before the start of car washing and end the operation (S13).

Next, another embodiment according to the present invention will be described. 30a to 33a shown in FIG.
Reference numerals 33b to 33b denote light receiving elements, each having a horizontal optical axis E to F.
Is formed, and the height of the vehicle body to be cleaned is detected. An optical axis H provided at a height of h1 from the ground is below the vehicle, an optical axis G provided at a height of h2 from the ground is a normal vehicle roof position, and an optical axis provided at a height of h3 from the ground. F detects a wagon vehicle roof position and constitutes first vehicle body detection means.
The optical axis E provided at the height h4 from the ground detects the height of the vehicle that cannot be washed by the car washer. If the car wash machine detects a car with a car height that cannot be washed, it will prohibit car wash reception, or if it detects a car height that cannot be washed during car washing,
Stop the car washer and the car wash processor and stop the car wash.
Therefore, the heights of the horizontal optical axes E to H are appropriately determined so as to conform to each purpose. In addition to the horizontal optical axis, diagonal optical axes A to D and A 'to D' shown in FIG. 3 are provided. Is detected.

The vehicle to be washed is a normal vehicle based on characteristic points on the vehicle shape, such as a vehicle body edge, a normal vehicle roof position, and a wagon vehicle roof position, which are detected by transmitting and blocking the horizontal optical axes E to H. , A wagon car, or a jeep type, and controls the upper surface cleaning brush according to a previously stored vehicle type for each vehicle type. The upper surface cleaning brush adopts a well-known swinging structure (not shown) that is connected to an actuator such as an air cylinder via an arm (not shown). When it is removed, it operates to descend by the weight of the brush. Therefore, the upper surface cleaning brush traces the upper surface of the vehicle body under the control of the air cylinder based on the general vehicle shape stored according to the vehicle type, and fine differences in the vehicle shape are absorbed by the swinging operation of the arm. The light transmitting / shielding state of the horizontal optical axis during the car washing process is stored in correspondence with the pulse input from the rotary encoder 5 for detecting the traveling position, and based on the stored contents, the first and subsequent steps are performed. Is performed. The detection of the vehicle body by the oblique optical axis is also performed in parallel with the detection of the horizontal optical axis. In particular, when the front or rear end of the vehicle body is detected by the horizontal optical axis H, the detection of the oblique optical axis is performed. When the transmissive / shielded state is asymmetrical, it is determined that a protrusion (custom mirror or rear mirror) exists on the vehicle body.

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, the detection of the vehicle shape when the vehicle is viewed from the side is not a method of performing image processing of binarized image data, but a known method of continuously detecting the highest point of the vehicle body with a sensor capable of moving up and down. A method is also acceptable.

Further, in the second vehicle body detecting means according to the embodiment, the light projecting element arranged on the upper part of the car washer and the light receiving element arranged on the left and right sides form four oblique optical axes on each of the right and left sides. However, the light receiving element may be disposed on one of the sides to form an oblique optical axis on one of the right and left sides. Even if an oblique optical axis is formed on one side, it is possible to determine whether at least the protrusion existing at the end of the vehicle body is on the left or right with respect to the vehicle width direction. Further, the number of light projecting / light receiving elements can be appropriately increased or decreased.

Further, in the embodiment, the car washer in which the car washer is moved to a predetermined position and the car washer body runs to wash the car body is described. A car washer that moves one or both of the car and the car for washing, or
A car washer in which an automobile is moved by a conveyor or the like to a fixed tunnel-shaped car wash machine main body to perform washing may be used.

[0032]

As described above, according to the present invention, a vehicle type is determined by detecting characteristic points on a vehicle shape such as a vehicle body edge, a normal vehicle roof position, a wagon vehicle roof position, and the like based on a horizontal optical axis. An oblique optical axis formed by arranging light emitting / receiving elements on the upper portion and side portions of the car washer body detects a vehicle width and a protrusion protruding from an end of the vehicle body. In particular, if a horizontal optical axis detects the front or rear end of the vehicle and a diagonal optical axis detects a protrusion, it is judged to be a breakable projection such as a custom mirror or rear mirror, so a safe and efficient car wash It can be performed.

The data on the presence / absence of a vehicle body in the vertical direction at predetermined intervals in the vehicle body length direction detected by the first vehicle body detecting means is directly recognized as binarized image data as it is, and in parallel with the binarized image data, Since the data relating to the presence / absence of the vehicle body in the left-right direction at predetermined intervals in the vehicle body length direction detected by the vehicle body detection means is stored, it is possible to easily obtain binarized image data corresponding to the actual size of the vehicle body. In addition, safe and efficient car washing can be performed based on the outline of the vehicle body viewed from the side and the vehicle body shape viewed from above.

Further, a plurality of light projecting / receiving elements are arranged on the upper and left and right sides of the body of the car washer straddling the vehicle body, and an optical axis composed of the upper part and the right part, and a light composed of the upper part and the left part. The axis intersects near the upper part of the vehicle body, and the vehicle width and the presence or absence of protrusions are determined from the blocked state of the left and right optical axes, so if there is a protrusion, the point where the blocked optical axes intersect It can be determined that a protrusion exists. Therefore, a relatively small number of light-emitting / light-receiving elements can detect not only the presence or absence of a protrusion but also highly accurate detection of whether the protrusion is on the left or right side of the vehicle width. Further, thereby, it is possible to wash as much as possible a portion that can be washed while avoiding only the protrusions, and it is possible to provide an efficient car wash with less unwashed residue.

Further, it is possible to judge whether the stop position of the car is appropriate or not at the same time as the vehicle width detecting operation when the car body is viewed from above, and when the car wash operation is hindered or there is a danger of an accident, A safe car washer that stops operating can be provided.
