Description

  The present invention relates to a car wash machine having a function of improving the drying performance of an automobile body.

  Conventional car wash machines are equipped with a drying device that mainly includes a top nozzle for drying the top surface of the vehicle body and a side nozzle for mainly drying the side surface of the vehicle body. The top nozzle is raised and lowered according to the shape of the top surface of the vehicle body. The side nozzle is opened and closed in accordance with the side shape of the vehicle body to improve the drying efficiency. These drying nozzles are arranged on the lower side of the side of the vehicle body so that mutual ventilation does not interfere, so when drying a car with a high vehicle height, such as a wagon car, However, there was a problem that water droplets remained easily.

  In this regard, in Patent Document 1, a sub-drying nozzle that faces the upper part of the side surface of the vehicle body is provided at the longitudinal end of the upper surface nozzle. According to this configuration, even when a vehicle having a high vehicle height such as a wagon car is dried, water droplets on the side surface of the vehicle body can be reliably removed. However, since the sub-drying nozzle is fixed and the air blowing direction is always constant, the sub-drying nozzle cannot be applied to an automobile whose side face is inclined or an automobile having a narrow vehicle width. In addition, since the stop position of the car depends on the skill of the driver, it may be stopped in a state where the car is deviated or skewed, and it is difficult to exert a uniform drying effect.

It is swung. Normally, the side upper blower nozzles 7 and 7 are in a position where the air blowing port 29 is directed slightly inward from the vertically downward direction with the lot portion of the air cylinder 34 being contracted (a), and air is introduced into the air cylinder 34. By extending the lot portion, it rotates around the lower part of the support piece 33 and swings to a position (b) oriented inward by the angle θ1 of the body frame 1 and a position (c) oriented further to the angle θ2 inward. To do.

  These blower nozzles, although not particularly shown, are supplied with high-pressure air by connecting the duct hoses 12 and 30 to the blower blower. A blower blower may be installed for each blower nozzle, or may be distributed to each blower nozzle via a branch air passage. Further, in this embodiment, an air cylinder is used as the swinging devices 17 and 32 and swings stepwise in units of a predetermined angle. However, it is possible to swing the head steplessly using a motor or the like. Also good.

  With such a configuration, the upper surface blower nozzle 6 is moved up and down along the shape of the upper surface of the vehicle body by the elevating device 16 and performs blower drying while appropriately maintaining a distance from the upper surface of the vehicle body. Moreover, the blower drying is performed at an appropriate air blowing angle with respect to the front and rear surfaces of the vehicle body by the front and rear swing device 17. The side upper blower nozzles 7 and 7 are swung in accordance with the shape of the side surface of the vehicle body by the left and right rocking device 32 and directed to the upper side of the vehicle body side to perform blower drying. Further, the front and rear swinging device 17 of the upper surface blower nozzle 6 is also swung in the front and rear direction of the vehicle body, and blower drying is performed on the front and rear surfaces of the vehicle body in cooperation with the upper surface blower nozzle 6.

FIG. 5 shows the configuration of the side surface shape detection device 11.
The shape detection unit 11a includes an ultrasonic sensor 31 that is formed on one inner surface of the main body frame 1 and detects the ingress of the automobile, and ultrasonic sensors 32a to 32d that are arranged at equal intervals L up and down. The vehicle width detection unit 11b includes an ultrasonic sensor 33 that is formed on the other inner surface of the main body frame 1 and is paired with the ultrasonic sensor 31 of the shape detection unit 11a.

  The ultrasonic sensors 31 and 33 are mounted with a ground height of 60 cm as a guideline from the viewpoint of reliable vehicle body recognition and the Fire Service Act, while protruding forward from the front surface of the main body frame 1 by the support arm 34, and are waiting to enter the vehicle. , The sensor 31 is used for transmission and the sensor 33 is used for reception (or vice versa), so that it functions as a transmission type detector and detects that an automobile has entered. Further, during the car wash, the sensors 31 and 33 function as a reflection type detector, send and receive ultrasonic waves to the side of the vehicle body, measure the distance from the side of the vehicle body, and detect the vehicle width and shape of the automobile.

  The ultrasonic sensors 32a to 32d are arranged on the inner surface of the main body frame 1 at an appropriate interval, send and receive ultrasonic waves to the side surface of the vehicle body, measure the distance from the side surface of the vehicle body, and detect the vehicle body detection point by each sensor in a straight line. Connect to detect side profile. The ultrasonic sensor 32a is located above the ultrasonic sensor 31 at the interval L, irradiates ultrasonic waves near the switching between the door and the window of the ordinary vehicle, and the ultrasonic sensor 32b is located above the ultrasonic sensor 32a at the interval L. The ultrasonic sensor 32c is positioned above the ultrasonic sensor 32b at a distance L from the ultrasonic sensor 32b, and emits ultrasonic waves near the window of the wagon car near the switching between the window of the normal car and the roof. The ultrasonic sensor 32d is positioned above the ultrasonic sensor 32c at an interval L and irradiates ultrasonic waves near the switching between the window and the roof of the wagon car.

  Thus, the vehicle body detection points are measured with the ultrasonic sensor 31 as the lowest position and the ultrasonic sensor 32d as the highest position, and are linearized based on the coordinate data of each detection point to detect the vehicle body side surface shape.

FIG. 6 is a block diagram showing the control system.
A car wash control board 35 includes a travel position detector 36, a top car shape controller 37, a side car shape controller 38, and a car wash controller 39. Based on information obtained from the travel encoder 9, the position, shape, Car shape data such as equipment is recognized and car wash processing devices such as brushes and blower nozzles are operated via the car wash drive board 40 based on this car shape data, and car washing is performed according to the position, shape, equipment, etc. of the car. Is what you do.

  The travel position detector 36 detects the travel position of the main body frame 1 by counting the pulse signals transmitted from the travel encoder 9.

The upper surface vehicle shape control unit 37 includes a vehicle shape detection unit 37a, an image processing unit 37b, a reference point recognition unit 37c, and a vehicle type determination unit 37d.
The vehicle shape detection unit 37 a takes in the light transmission / shielding data of the top surface shape detection device 10 by using a pulse signal from the travel encoder 9 accompanying the travel of the main body frame 1 as a trigger, and provides the travel position detection unit 36 of the main body frame 1. Binary image data is created in correspondence with the travel position. The binary image data created in this manner is developed in a matrix of pixels with the horizontal axis as the predetermined running pitch of the car wash machine body 1 and the carriage 11 and the vertical axis as the optical axis arrangement pitch. In the case of shading, it is expressed as black.

  The image processing unit 37b performs image processing on the binary image data created by the vehicle shape detection unit 37a and extracts the upper surface contour of the automobile. Image processing applies a logical filter with a predetermined condition to all the pixels of the binary image data, changes the binary data of the detection pixel according to the adjacent pixel pattern, and the boundary between the light-transmitting pixel and the light-shielding pixel in the vertical direction. The upper surface contour of the automobile which is continuous in the horizontal direction is extracted with the pixel as the upper surface position of the vehicle body.

  The reference point recognition unit 37c recognizes the vehicle body front end, the boundary between the bonnet and the windshield, the roof front end, the roof rear end, and the vehicle body rear end, which are reference points of the automobile, based on the upper surface contour. That is, the front end of the vehicle body is recognized by detecting a point where the upper surface level exceeds a preset vehicle body lower limit height. The boundary between the bonnet and the windshield is the upper surface while the main body frame 1 travels a predetermined distance until the upper surface level reaches a predetermined roof lower limit height and on the condition that the predetermined distance from the front end of the vehicle body A point where the level has increased by a predetermined value or more is detected and recognized. In a one-box vehicle, since there is no bonnet, there is no part that satisfies this condition, so when the upper surface level reaches the roof lower limit height, give up recognition of the boundary and move to recognition of the next reference point. . The front edge of the roof is recognized by detecting a point where the upper surface level does not rise above a predetermined value while the main body frame travels a predetermined distance on condition that the upper surface level is equal to or higher than a predetermined roof lower limit height. . The rear end of the roof is recognized by detecting a point where the upper surface level has dropped by a predetermined value or more from the height of the front end of the roof. The rear end of the vehicle body is recognized by detecting a point where the upper surface level is below the vehicle body lower limit height.

  The vehicle type discriminating unit 37d discriminates the vehicle type of the automobile to be cleaned from the automobile reference point recognized by the reference point recognizing unit 37c. That is, if there is a boundary between the bonnet and the windshield, a normal vehicle is identified, and if there is no boundary, a one-box vehicle is identified.

The side surface shape control unit 38 includes a sensor drive unit 38a, a distance calculation unit 38b, a control point detection unit 38c, and a data creation unit 38d.
The sensor drive unit 38a uses the pulse signal of the travel encoder 9 output every time the main body frame 1 travels a predetermined distance as a trigger, shifts the transmission / reception selection signal to the ultrasonic sensor to be driven, and then generates an ultrasonic wave. A signal is output and at the same time a received signal of a reflected wave is received.

  The distance calculation unit 38b measures the distance from the sensor to the vehicle body surface based on the time from ultrasonic oscillation to reception of the reflected wave, and creates coordinate data. That is, the coordinate data is created by setting the measurement distance to the vehicle body detection point horizontally as X and the sensor mounting height as Y horizontally with the ultrasonic sensor.

  The control point detection unit 38 c is a target control when swing control of the side surface upper blower nozzles 7 is performed from the detected coordinate data of the vehicle body detection point and the vehicle body upper surface position detected by the upper surface vehicle shape control unit 37. Set a point. This control point is hypothesized on a straight line that approximately connects the detection points at a position offset downward from the boundary between the side surface of the vehicle body and the roof surface assuming a visor.

  The data creation unit 38d hypothesizes a boundary point on the opposite side of the vehicle body point set by the control point detection unit 38c, on the assumption that the vehicle body is substantially symmetrical.

  The car wash control unit 39 includes the travel position data of the main body frame 1 obtained by the travel position detection unit 36, the upper surface vehicle shape data obtained by the upper surface vehicle shape control unit 37, and the side surface vehicle shape obtained by the side surface vehicle shape control unit 381. The car wash driving unit 41 is controlled based on the data to drive the brushes and nozzles.

Next, the operation of the present invention configured as described above will be described.
A car wash user enters a car wash fee in the operation box CB, selects a desired car wash menu, and then enters the car. When it is detected by the ultrasonic sensors 31 and 33 of the main body frame 1 that the automobile has stopped at a predetermined stop position, a vehicle shape detection process and a brushing cleaning process are executed as the main body frame 1 travels.
In the vehicle shape detection process, the upper surface shape detection device 10 and the side surface shape detection device 11 recognize the upper surface shape and the side surface shape of the vehicle while detecting the travel position of the main body frame 1 with the travel encoder 9, and the shapes of the upper surface and the side surface of the vehicle body are recognized. When the detection is performed and the travel of the main body frame 1 is completed, the shape detection of the entire vehicle is completed.
In the brushing cleaning process, while the cleaning water and the detergent water are discharged from the watering nozzle, the upper surface brush 4 is driven along the shape of the upper surface of the vehicle to perform the brushing cleaning of the upper surface of the vehicle body, and the side brushes 5 and 5 are opened and closed to move the vehicle. Brush the front, side, and rear of the machine.

Next, the brushing cleaning process is executed again along with the return of the main body frame 1, and when the cleaning is completed, the drying process accompanying the outward movement of the main body frame 1 is executed.
In the drying process, the upper surface blower nozzle 6 moves up and down along the shape of the upper surface of the vehicle and blows air to the upper surface of the vehicle as close as possible to the vehicle body. The oscillating position is displaced and the air is blown toward the upper side of the vehicle body, and the lower side blower nozzles 8 and 8 blow the air toward the lower side of the vehicle body to dry the washed vehicle body.

Hereinafter, the operation of the drying process will be described in detail.
The air blown from the upper surface blower nozzle 6 mainly acts on the upper surface of the vehicle body of the automobile A, and blows off the remaining water droplets while driving the main body frame 1 backward. The air blow from the side upper blower nozzles 7 and 7 mainly acts on the upper side of the vehicle body, and blows off the remaining water droplets while driving down the vehicle body. The air blown from the side lower blower nozzles 8 and 8 mainly acts on the lower part of the side of the vehicle body, and blows off remaining water droplets and water droplets flowing from the upper surface of the vehicle body.

  Now, the air blown from the side upper blower nozzles 7 and 7 is blown to the vehicle body by the cylindrical nozzle body 27 with almost no loss, diffuses along the vehicle body surface by the Coanda effect, and dries to remove water droplets over a wide area. Power is demonstrated. For this reason, if the blown air diffuses, it interferes with the blown air from the upper surface blower nozzle 6 and water droplets are likely to stay in the canceled part, and the water droplets are scattered on the surface of the vehicle body that has been dried. There is. Therefore, the front and rear rocking device 17 and the left and right rocking device 32 are controlled according to the vehicle body part detected by the upper surface vehicle shape control unit 37 so as to blow air in an optimum rocking mode.

FIG. 7 shows the swinging operation of the side upper blower nozzles 7 for each vehicle body part.
In area A (drying start position to front end of vehicle body + α), the left / right swing device 32 causes the left and right side surface upper blower nozzles 7 and 7 to be directed most inwardly (FIG. 4 c), and the front / back swing device 17. Then, the upper surface blower nozzle 6 is inclined in the traveling direction (FIG. 3c), and air is concentrated on the front grill to improve the drying performance.
In area B (vehicle body front end + α to roof front end), the left and right side upper blower nozzles 7, 7 are not inclined (FIG. 4a) to prevent water droplets from splashing on the bonnet and windshield.
In the area C (roof front end to roof rear end), the swing angle of the left and right side upper blower nozzles 7 and 7 is controlled so as to blow toward the control points Pr and Pr ′ set by the side wheel shape control unit 38. .
In area D (the roof rear end to the vehicle body rear end), the left and right side upper blower nozzles 7 and 7 are in the most inwardly directed state (FIG. 4c), and the upper and lower swinging device 17 advances the upper blower nozzle 6. In a state of being inclined in the direction opposite to the direction (FIG. 3b), the blowing performance is concentrated on the rear surface of the vehicle body to improve the drying performance.

  As shown in FIGS. 8 to 11, the swing control in the area C is performed independently for the left and right side upper blower nozzles 7 and 7 so as to be directed to the control points Pr and Pr ′ set by the side wheel shape controller 38. A normal car that has stopped normally (Fig. 8), a car that has deviated to the left or right / an ordinary car that has stopped diagonally (Fig. 9), and a one-box vehicle with a gentle slope on the upper side of the vehicle body (Fig. 8) 10) Even in a light vehicle (FIG. 11) having a narrow upper surface width, the lateral upper and lower blower nozzles 7 and 7 can be oriented in accordance with the control points Pr and Pr ′ by adjusting the left and right swing angles. it can.

  Thus, when the automobile exits the drying section, the drying process is completed. Thereafter, the automobile A is urged to move forward and leave the car wash area. When the car exit is detected, the main body frame 1 is returned to the standby position at the rear end of the rail to prepare for the next car wash.

  As described above, in the present invention, since the side surface upper blower nozzles 7 and 7 are provided on the side surface of the upper surface blower nozzle 6, it is possible to efficiently and surely blow away water droplets that are likely to remain on the window portion on the side surface of the vehicle body. Moreover, since the side upper blower nozzles 7 and 7 are formed of a cylindrical nozzle body, they are sprayed onto the vehicle body with little loss, diffuse along the vehicle body due to the Coanda effect, and act on a wide area on the vehicle body side surface. There can be very little residual droplets. Further, since the upper surface blower nozzle 6 can be moved up and down and back and forth and the side surface upper blower nozzles 7 and 7 can be swung left and right, a drying configuration corresponding to the vehicle type and the vehicle body part is possible. Further, since the side upper blower nozzles 7 and 7 are made to swing freely, when drying an intricate part of the vehicle body shape, for example, around the door mirror, the traveling of the main body frame is decelerated or stopped to thereby reduce the side upper blower nozzles 7 and 7. The drying effect can be further enhanced by swinging the.

  In addition, this invention is not limited to the said Example, A various embodiment can be considered in the range which does not deviate from description of a claim. In the embodiment, the cleaning part is formed at the front side of the main body frame 1 and the drying part is formed at the rear side. However, the drying part is provided at the front side as in the case of a widely used portal type car wash machine. Needless to say, the present invention can be applied to a vehicle having a washing section and performing a car washing operation by reciprocating travel of the main body. Further, the present invention can be similarly applied to a car wash machine in which an automobile is run in the main body frame and washed. Further, although the cleaning unit S of the embodiment performs brushing cleaning, it is apparent that the cleaning unit S can be applied to a brushless car washer that does not have a brush and performs cleaning with high-pressure spray. In addition, the side upper blower nozzles 7 and 7 can be swung independently in the front-rear direction, and only the side upper blower nozzles 7 and 7 are directed to the front and rear surfaces of the vehicle body, or can be swung back and forth depending on the vehicle body part. May be.
