Description

  TECHNICAL FIELD The present invention relates to a car washer having a washing unit provided with a washing nozzle for spraying washing water or a foaming detergent onto an automobile body, separately from a main body.

  Generally, this type of car washer comprises a gate-shaped main body frame, a vehicle shape detecting device for detecting the shape of the vehicle, a cleaning brush for brushing and cleaning the vehicle body surface, and a drying nozzle for blower drying the vehicle body surface. A processing device is provided, and the main body frame is run across the automobile to wash and dry the vehicle body surface. Further, as a car washing processing device, a car washing machine provided with a jet nozzle for jetting high-pressure washing water and a foam nozzle for spraying foamed detergent is also known.

  The car washing process is executed by detecting the shape of the automobile with the vehicle shape detecting device, and moving the cleaning brush and the drying nozzle to and away from the vehicle body based on the detected vehicle shape. In addition, high-pressure cleaning by a jet nozzle and foam dispersion by a foam nozzle are executed before brushing cleaning by a cleaning brush. For this reason, the vehicle shape detecting device, the jet nozzle, and the foam nozzle are arranged at a position preceding the cleaning brush in the main body frame. The layout will be relatively close. As a result, the washing water and the foamed detergent from the jet nozzle and the foam nozzle affect the vehicle shape detection by the vehicle shape detection device, and it is difficult to accurately detect the vehicle shape. In addition, if high-pressure washing or foam spraying is performed separately from vehicle shape detection, the car washing time becomes longer.

  Accordingly, an object of the present invention is to provide a car washer that implements high-pressure washing and foam spraying without affecting the vehicle shape detection by the vehicle shape detection device.

  In order to solve such a problem, the present invention relates to a car wash machine in which a car wash body is formed by reciprocating a gate-shaped car wash machine body to perform car wash processing on a car body with a car wash processing device provided in the body. A cleaning unit that supplies a cleaning liquid to the vehicle body is provided at a front position of the main body at a predetermined distance from the upper front surface of the vehicle, a cleaning nozzle that sprays a cleaning agent toward the vehicle body toward the cleaning unit, and the cleaning nozzle is swung in the front-rear direction. A movable tilt device.

  When the cleaning nozzle of the cleaning unit is located behind the front end of the vehicle, the control device is configured to execute a front cleaning operation of operating the tilt device to spray a cleaning liquid from the cleaning nozzle toward the front end of the vehicle. Further, a control unit is provided for executing a rear surface cleaning operation of operating a tilt device to spray a cleaning liquid from the cleaning nozzle toward the rear surface of the vehicle when the cleaning nozzle of the cleaning unit is located behind the rear end of the vehicle.

  The control means simultaneously executes the washing operation of spraying the washing liquid from the washing nozzle of the washing unit onto the car body and the car shape detecting operation of detecting the shape of the car with the car body detecting sensor of the car washing machine body in accordance with the forward movement of the car washing machine body. At the same time, the vehicle shape detection operation is stopped at the timing when the tilt device is operated. In addition, the washing operation of spraying the washing liquid onto the car body from the washing nozzle of the washing unit and the car shape detecting operation of detecting the shape of the car with the car body detection sensor of the car washing machine main body are simultaneously executed with the first forward movement of the car washing machine main body. In addition, the car wash operation of washing the car body with the car wash processing device of the car wash machine body and the car shape detection operation of detecting the shape of the car with the car body detection sensor of the car wash machine body are performed with the next forward movement of the car wash machine body. Run at the same time.

  According to the present invention, a washing unit for injecting a washing liquid into an automobile body is provided at a front position of the body at a predetermined distance from an upper front surface of a car wash machine equipped with a car body detection sensor and a car wash processing device, and separated from the car wash machine body. By injecting the washing liquid from the washing nozzle of the washing unit, the washing water is applied to the vehicle body detection sensor of the car washer body, thereby reducing the influence on the vehicle shape detection. In addition, by injecting the washing liquid from a washing unit separate from the car wash machine main body, the washing form and the washing power are appealed to the surroundings, thereby contributing to the improvement of customer attractability and the demand for washing.

  Also, even if the stop position of the car receiving the car wash is set at the front of the car wash machine body as in the case of the conventional car wash machine, the washing liquid is supplied to the car by providing the tilt device for swinging the washing nozzle back and forth. The cleaning liquid can be sprayed on the front and rear surfaces, and there is no need to expand the car wash space. Further, when the cleaning nozzle of the cleaning unit is located behind the front end of the vehicle, the tilt cleaning device is operated to perform a front cleaning operation of spraying a cleaning liquid from the cleaning nozzle toward the front end of the vehicle. When the vehicle is behind the rear end of the vehicle, the tilting device is activated to perform a rear cleaning operation of spraying a cleaning liquid from the cleaning nozzle toward the rear surface of the vehicle, thereby uniformly cleaning the front and rear surfaces of the vehicle. Can be.

  In addition, the washing operation of spraying the washing liquid onto the car body from the washing nozzle of the washing unit and the car shape detecting operation of detecting the shape of the car with the car body detection sensor of the car washing machine body are simultaneously executed along with the forward movement of the car washing machine body. By stopping the vehicle shape detection operation at the timing when the tilt device is operated, the influence of the cleaning operation on the vehicle shape detection operation can be minimized, and preliminary vehicle shape data of the vehicle can be created. Furthermore, the car wash operation of washing the car body with the car wash processing device of the car wash machine body and the car shape detection operation of detecting the shape of the car with the car body detection sensor of the car wash machine body are simultaneously performed with the next forward movement of the car wash machine body. By executing, normal vehicle shape data can be created. The formal vehicle shape is grasped while supplementing data with the preliminary vehicle shape data and the normal vehicle shape data created in this way, and when a deviation occurs, it is used for detecting abnormalities such as occurrence of self-propelled or car wash machine slip. be able to.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an external view showing a car washer of the present invention, and FIG. 2 is a side view of the car washer.
Reference numeral 1 denotes a car washing machine main body, which is formed in an arch shape, reciprocates on a pair of left and right rails 2.2, and moves across a vehicle stopped between the rails 2.2. The main body 1 of the car washer reciprocates in a traveling range provided on the rails 2 by a traveling motor 3 that can be rotated forward and backward, and receives a pulse signal from a traveling encoder 4 linked to an output shaft of the traveling motor 3 to travel. The position is detected.

  5, 6, and 6 are cleaning brushes, 5 is a top brush that moves up and down along the vehicle body surface and mainly cleans the upper surface of the vehicle body, and 6 and 6 are opening and closing operations along the vehicle body surface to clean the side surfaces and front and rear surfaces of the vehicle body. It is a pair of left and right side brushes. 7, 8, and 8 are drying nozzles, 7 is a top nozzle that moves up and down along the body surface and mainly blows high-pressure air to the upper surface of the vehicle body, and 8.8 is a pair of left and right side nozzles that mainly blow high-pressure air to the side surface of the vehicle body. It is.

  A washing unit 9 has a built-in high-pressure spray nozzle 10 for spraying high-pressure wash water onto the vehicle body surface and a foam spray nozzle 11 for spraying foam detergent, and is supported by a support arm 12 attached to the top surface of the car wash machine body 1. It is installed at a position protruding forward by a predetermined distance L from the front of the car washer body 1.

FIG. 3 shows the internal structure of the cleaning unit 9 as viewed from the front.

Reception, selection of a car wash course, a car wash start command, and the like.

The operation of the car washer thus configured will be described.
When the reception of the car wash is completed by the car wash reception device 73, the illumination indicator 33 switches from the standby display to the entry guidance display, and guides the vehicle to enter. If the photoelectric switch 35a provided in front of the car washer body 1 blocks light and the vehicle body detector 34 keeps transmitting light for a predetermined time, it is detected that the car has stopped at the stop position, and the car wash operation is started. You. When the foam jet car wash is selected as the car wash course, the next washing step is sequentially performed in accordance with the reciprocation of the car wash machine body 1.

○ First outbound process (Fig. 9)
In the first outbound process, jet washing is performed in which washing water is injected at high pressure from the high-pressure injection nozzle 10 of the washing unit 9 onto the vehicle body surface as the car wash machine main body 1 travels. Jet cleaning is performed by injecting high-pressure washing water from the high-pressure injection nozzle 10 while operating the slide device 19 of the washing unit 9 to slide the traveling carriage 13 in the lateral direction.

  At the beginning of the first outbound process, before the car wash machine body 1 starts going forward, the tilt device 26 is operated to direct the washing unit 9 to the inside of the car wash machine body 1, and the washing water is supplied from the high-pressure injection nozzle 10. Is injected toward the front of the vehicle body (FIG. 9A). This is an operation for compensating for insufficient washing near the front end of the vehicle body caused by the washing unit 9 being installed at a position protruding forward by a predetermined distance L from the front surface of the car washer body 1.

  After that, the washing unit 9 is returned to the horizontal posture, the injection direction of the high-pressure injection nozzle 10 is set to be vertically downward, and then the traveling of the car wash machine body 1 is started while the sliding of the traveling carriage 13 by the slide device 19 is started (FIG. 9b). Due to the sliding of the traveling vehicle 13, the high-pressure injection from the high-pressure injection nozzles 10 acts over the entire width of the vehicle, so that the upper surface and the side surfaces of the vehicle body are evenly washed.

  When the forward movement of the car washer body 1 proceeds and the photoelectric switch 35a passes through the rear end of the vehicle body and turns to light transmission, the tilt device 26 is operated to direct the washing unit 9 to the inside of the car wash machine body 1, and the high-pressure injection nozzle Cleaning water is injected from 10 toward the rear surface of the vehicle body (FIG. 9c). At this time, if the running speed of the car wash machine body 1 is temporarily stopped or reduced, the washing effect can be enhanced.

  Thereafter, when it is detected that the car wash machine body 1 has traveled a predetermined distance in response to a pulse signal from the travel encoder 4, the washing unit 9 is returned to the horizontal position, the washing unit 9 is stopped, and the first forward step is completed. (FIG. 9d).

  In the first forward step, a pulse signal from the traveling encoder 4 is received, and the result of detection of the vehicle body by the vehicle body detector 34 is taken in, and the traveling position of the car washer body 1 is detected and the vehicle shape data is created. At this time, the washing water scattered by the high-pressure injection of the washing unit 9 may affect the detection of the vehicle body by the vehicle body detector 34. In particular, at the timing when the washing unit 9 is directed toward the inside of the car wash machine main body 1 and the rear surface of the vehicle body is jet-cleaned (FIG. 9C), the injection from the cleaning unit 9 may directly adhere to the vehicle body detector 34. Therefore, when the photoelectric switch 35a passes through the rear end of the vehicle body and changes to light transmission, the acquisition of the vehicle body detection result of the vehicle body detector 34 is stopped. The vehicle shape data thus created is incomplete data in which the rear shape of the vehicle is not detected. It is used for detecting abnormalities such as running and car wash slip. It is desirable to equip the front surface of the vehicle body detector 34 with an openable / closable lid so that the lid is closed when taking in is stopped.

○ First return process (Fig. 10)
In the first return process, as the car wash machine body 1 returns, foam spraying is performed to spray foam detergent from the foam spray nozzle 11 of the washing unit 9 onto the vehicle body surface. Foam spraying is performed by spraying foam detergent from the foam spray nozzle 11 while operating the slide unit 19 of the cleaning unit 9 to slide the traveling carriage 13 in the horizontal direction, similarly to the jet cleaning.

  When the first return process starts, before the car wash machine body 1 starts the regression, the tilting device 26 is operated at the position where the car wash machine body 1 has completed the first forward process to cause the washing unit 9 to move the car wash machine body. 1 and the sliding of the traveling carriage 13 by the slide device 19, and the foaming detergent is sprayed from the foam spraying nozzle 11 toward the rear surface of the vehicle body (FIG. 10a).

  Thereafter, when the car wash machine body 1 starts going back and the photoelectric switch 35a goes back to a position where light is blocked at the rear end of the vehicle body, the washing unit 9 is returned to the horizontal posture, and the slide of the traveling cart 13 by the slide device 19 is maintained. Meanwhile, the jetting direction of the foam spray nozzle 11 is returned vertically downward (FIG. 10B).

  The return of the car washer body 1 proceeds, and foam detergent is sprayed evenly on the upper and side surfaces of the vehicle body (FIG. 10c). When the car wash machine body 1 returns to the car wash start position, the tilt device 26 is operated to direct the washing unit 9 to the inside of the car wash machine body 1 and spray the foam detergent from the foam spray nozzle 11 toward the front of the vehicle body. (FIG. 10d). Thereafter, when a predetermined time elapses, the cleaning unit 9 is returned to the horizontal posture, the cleaning unit 9 is stopped, and the first outward step is completed.

  In this manner, after the foam jet cleaning is performed by the cleaning unit 9 with the reciprocation of the car washer body 1, the same car washing process as before is performed with the 1.5 reciprocation of the car wash machine body 1.

  That is, in the second going process, a pulse signal of the traveling encoder 4 is received, a vehicle body detection result of the vehicle body detector 34 is taken in, the traveling position of the car washer body 1 is detected, and vehicle shape data is created. While spraying shampoo from the pipe 37 and washing water from the wax spray pipe 38 and the water spray pipe 39, brushing washing is performed while moving the top washing brush 8 and the side washing brush 9.9 to and from the vehicle based on the detected vehicle shape. Is performed. The vehicle shape data created here is used for movement control of the upper surface cleaning brush 8 and the like as normal vehicle shape data in which the upper surface shape is detected over the length of the vehicle. By complementing the data with the preliminary data detected in the first outbound process, a more accurate vehicle shape can be grasped.

  In the second return process, washing water is sprayed from the liquid agent spray pipe 37 and the water spray pipe 39 and wax (or a water repellent) is sprayed from the chemical spray pipe 38 based on the vehicle shape data created in the second outward process. Perform brushing cleaning. At this time, rinsing may be performed by injecting high-pressure cleaning water from the high-pressure injection nozzle 10 of the cleaning unit 9.

  Further, in the third outward step, the drying nozzles 5, 6 and 6 are applied to each surface of the vehicle body based on the vehicle shape data created in the second outward step, and blow drying is performed by high-pressure air.

  As described above, the present invention is provided with a cleaning unit that injects a cleaning liquid to an automobile body at a position separated from the front surface of the car wash machine body by a predetermined distance, and various embodiments can be considered without departing from this configuration. Can be For example, the structure of the car washer can be adopted in any of a type in which an automobile is transported to a stationary main body frame and a type in which both the automobile and the main body frame are movable.
