<First Embodiment>
Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 are a side view and a front view showing the car wash machine of the first embodiment. The car wash machine WA includes a car wash machine body 1, a rail 2, and a remote panel 7. The car wash machine main body 1 is formed in a gate shape having two left and right opposing stand portions 90 and a ceiling portion 91 connecting the upper ends of the stand portions 90.

  A pair of left and right rails 2 are provided on the ground G, and wheels 3 provided on the bottom surface of the stand portion 90 are arranged on the rail 2. Thus, the car wash machine body 1 is erected on the rail 2, travels on the rail 2 by driving of a travel motor (not shown), and moves back and forth with respect to the vehicle CA to be cleaned.

  The remote panel 7 is arranged along the approach path A with respect to the car wash machine body 1. The remote panel 7 has a plurality of buttons and sets car wash conditions. Car washing conditions can be set with or without a washing method (washing with water, shampooing, coating, etc.) and equipment (front guard, fender pole, side under mirror, rear wiper, roof spoiler, roof carrier, etc.) .

  An operation panel 8 is disposed in front of one stand portion 90 of the car wash machine body 1. The operation panel 8 can set car wash conditions in the same manner as the remote panel 7. The remote panel 7 and the operation panel 8 constitute an operation unit for setting a car wash condition.

  A shape sensor 9 and a distance measuring sensor 11 are provided on the entrance surface 1 a side of the stand portion 90 of the car wash machine body 1. The shape sensor 9 is formed by a plurality of photoelectric sensors arranged in parallel in the vertical direction on the stand portion 90. The shape of the to-be-cleaned vehicle CA is detected by passing the to-be-washed vehicle CA between the light projecting portion provided on the one stand 90 and the light-receiving portion provided on the other stand 90. Thereby, the front position, vehicle height, and vehicle length of the to-be-cleaned vehicle CA can be detected.

  The distance measuring sensor 11 is formed by an ultrasonic sensor, a photoelectric sensor or the like, and a pair of left and right distance measuring sensors 11 attached to both stand portions 90 are arranged with the vehicle CA to be cleaned interposed therebetween. The distance measuring sensor 11 measures the distance to the side surface of the vehicle to be cleaned CA by reflection of ultrasonic waves, infrared rays or the like. Thereby, the vehicle width of the to-be-cleaned vehicle CA can be detected. A pair of left and right distance measuring sensors 11 sandwiching the vehicle to be cleaned CA may be provided on a support stand standing on the ground G.

  The car wash machine main body 1 is provided with a plurality of rotating brushes that slide and brush on the vehicle to be cleaned CA. The rotating brush includes a top brush 4, a side brush 5 and a rocker brush 6.

  The top brush 4 is provided on the ceiling portion 91 so as to be movable up and down, and rotates on a horizontal rotating shaft to clean the upper surface of the vehicle CA to be cleaned. The rocker brush 6 is provided at the lower part of both stand parts 90 so as to be able to advance and retreat in the left-right direction, and rotates on a vertical or horizontal rotating shaft to wash the lower parts on both sides of the vehicle CA to be cleaned.

  The side brush 5 is provided on the exit surface 1b side of both stand portions 90 so as to be able to advance and retreat in the left-right direction. Further, the side brush 5 is supported at the upper end of the rotating shaft and is arranged to be tiltable in the left-right direction and the front-rear direction.

  A blower 20 that generates an airflow is disposed on the upper part of the car wash machine body 1. The blower 20 is connected to a plurality of blowing nozzles that send out an air flow toward the vehicle to be cleaned CA. The blower nozzle includes a top blower nozzle 21 and a side blower nozzle 22.

  The top blowing nozzle 21 is provided on the ceiling 91 so as to be movable up and down, moves along the upper surface and the rear surface of the vehicle CA to be cleaned, and dries the front surface, the upper surface, and the rear surface of the vehicle CA to be cleaned by blowing air. The side blowing nozzles 22 are respectively provided on both stand portions 90, and dry the side surface of the vehicle CA to be cleaned by blowing.

  The stand unit 90 is provided with a tank storage unit 30 for storing a plurality of liquid storage tanks (not shown). Various liquids such as detergents and coating agents are stored in the liquid storage tank. Distributing piping 31 for distributing the city water and the liquid agent from each liquid storage tank is provided above the tank housing 30. A plurality of injection nozzles 12 are led out to the distribution pipe part 31 via electromagnetic valves (not shown). The injection nozzle 12 is provided on the ceiling portion 91 and the stand portion 90 and injects city water cleaning water, cleaning water containing a detergent, a coating agent, and the like toward the vehicle CA to be cleaned.

  In the car wash machine WA having the above configuration, when the vehicle CA to be cleaned stops in front of the surface of the remote panel 7, the car wash conditions are set. After setting the car wash conditions, the car wash is started when the car CA to be washed moves to a predetermined washing start position and stops by the user's driving.

  For example, when car wash is started by selecting shampoo washing, a first outward path process in which the car wash machine main body 1 moves toward the rear of the vehicle to be washed CA is performed. Since it is arranged on the entrance surface 1a side in the first outward path process, the shape of the vehicle CA to be cleaned is detected by the shape sensor 9 and the distance measuring sensor 11 preceding each rotary brush. In addition, cleaning water containing a detergent is sprayed from a predetermined spray nozzle 12, and the front and rear surfaces, both side surfaces, and the top surface of the vehicle CA to be cleaned are cleaned by each rotating brush.

  When the cleaning is completed up to the rear surface of the vehicle CA to be cleaned, a first return path process is performed in which the car washer main body 1 is reversed and moved in front of the vehicle CA to be cleaned. In the first return pass process, city water wash water is jetted from a predetermined jet nozzle 12, and each rotary brush rotates to rinse the detergent with water.

  When the first return path process is completed, a second forward path process is performed in which the car washer main body 1 is reversed and moved rearward of the vehicle to be cleaned CA. In the second forward path process, the rotating brush is stopped, and air is blown from each blowing nozzle to dry the vehicle CA to be cleaned. This completes the car wash.

  When water washing is selected as the car wash condition, city water is jetted from a predetermined jet nozzle 12 in the first forward pass process. When the coating is selected as the car wash condition, the coating agent is sprayed from the predetermined spray nozzle 12 in the second forward path process and the second backward path process after the first backward path process. As a result, a film of the coating agent is formed on the vehicle to be cleaned CA, and drying is performed in the third outward path process.

  FIG. 3 is a top view showing the operation of the side brush 5 in the first forward path step. The side brush 5 is disposed at a position where the distance between the center of rotation and the cleaning surface of the vehicle CA to be cleaned is smaller than the rotation radius by a predetermined amount, and performs cleaning by sliding on the cleaning surface by rotation.

  The side brushes 5 arranged at the standby position S0 are arranged close to each other at the position S1. Next, it is arranged at a position S5 that slides on the front surface of the vehicle to be cleaned CA by the movement of the car wash machine body 1 or a position S5 'that will be described later. The position of the front surface of the vehicle to be cleaned CA is detected by the shape sensor 9 preceding the side brush 5.

  When the side brush 5 is arranged at the position S5 or the position S5 ', the car wash machine main body 1 stops and the side brush 5 moves in a direction away from each other. As a result, the front surface of the vehicle CA to be cleaned is cleaned, and the side brush 5 is arranged at the position S10 at the front end of both side surfaces of the vehicle CA to be cleaned.

  Next, the car wash machine body 1 moves toward the rear of the vehicle to be cleaned CA, and the side surface of the vehicle to be cleaned CA is cleaned. At this time, the side brush 5 advances and retreats according to the inclination angle in the left-right direction, and the distance from the side surface of the vehicle CA to be cleaned is kept constant. When the side brush 5 is disposed at the position S11 on the rear end of both side surfaces of the vehicle CA to be cleaned, the car wash machine body 1 stops, and the side brushes 5 are disposed close to each other at the position S12. Thereby, the rear surface of the vehicle CA to be cleaned is cleaned. Further, in the first return path process, the side brush 5 moves in the opposite direction to the first outbound path process, and cleaning is performed.

  FIG. 4 is a top view for explaining the detailed operation when the front surface of the vehicle CA to be cleaned is cleaned by the side brush 5 in the first forward path step. In the first return path process, the side brush 5 moves in the reverse direction of the first forward path process.

  When the front surface of the vehicle to be cleaned CA is cleaned by the side brush 5, a first front surface cleaning mode and a second front surface cleaning mode that are selectively switched according to the vehicle width of the vehicle to be cleaned CA are provided. The second front surface cleaning mode performs cleaning with a smaller pressing force than the first front surface cleaning mode, and prevents damage to the capacitor fins close to the front surface of the vehicle.

  When the vehicle CA to be cleaned is a small vehicle, the frequency of the proximity of the front surface of the vehicle and the capacitor is high. For this reason, the first front cleaning mode is executed when the vehicle width of the vehicle to be cleaned CA is larger than the predetermined value, and the second front cleaning mode is executed when the vehicle width is less than the predetermined value. Further, in the mini vehicle, the front surface of the vehicle and the capacitor are very close to each other. For this reason, in the present embodiment, the second front surface cleaning mode is executed when the width of the vehicle CA to be cleaned is 1480 mm or less, which is the standard for light vehicles, and the first front surface cleaning mode is executed when it exceeds 1480 mm.

  In the first front surface cleaning mode, the side brush 5 rotates at a predetermined rotation speed (for example, 125 rpm), moves from the position S1 (see FIG. 3), and is disposed at a position S5 that slides on the front surface of the vehicle CA to be cleaned. . At this time, the rotation center of the side brush 5 is disposed at a distance D1 (see FIG. 4) from the front surface of the vehicle CA to be cleaned. Thereafter, the side brush 5 moves in the left-right direction with the car wash machine main body 1 stopped, and cleans the front surface of the vehicle CA to be cleaned, and is disposed at the position S10.

  In the second front surface cleaning mode, the side brush 5 rotates at the same rotational speed as in the first front surface cleaning mode, and travels on a different path from the first front surface cleaning mode. In FIG. 4, a path different from the first front surface cleaning mode of the side brush 5 in the second front surface cleaning mode is indicated by a broken line arrow E in the drawing.

  When the side brush 5 moves from the position S1 (see FIG. 3) to a position S5 'that slides on the front surface of the vehicle to be cleaned CA, the car wash machine body 1 stops. At this time, the rotation center of the side brush 5 is arranged at a distance D2 from the front surface of the vehicle CA to be cleaned. The distance D2 is larger than the distance D1 in the first front surface cleaning mode.

  Next, the side brush 5 moves in the left-right direction and cleans the front surface of the vehicle CA to be cleaned. And if the side brush 5 is distribute | arranged to position S6 on the front surface of the to-be-cleaned vehicle CA, the movement of the left-right direction will be stopped and the car wash machine main body 1 will move. Thereby, the side brush 5 is distribute | arranged to position S7, and the car-washing machine main body 1 stops. At the position S7, the rotation center of the side brush 5 is arranged at the same distance D1 from the front surface of the vehicle to be cleaned CA as in the first front surface cleaning mode. And the side brush 5 moves to the left-right direction, and is distribute | arranged to position S10.

  Since the distance D2 is larger than the distance D1 in the central section Tm from the position S5 'to the position S6, cleaning is performed with a smaller pressing force than in the first front surface cleaning mode. The condenser that is air-cooled by running the vehicle is disposed in the vicinity of the central portion having a flat front shape. For this reason, it is possible to prevent the capacitor fins from being damaged by reducing the pressing force of the side brush 5 with respect to the section Tm in the front center portion of the vehicle CA having a small vehicle width.

  Further, in the section Te at both end portions from the position S7 to the position S10, cleaning is performed with the same pressing force as in the first front surface cleaning mode. For this reason, the detergency of both side ends can be improved. The section Te is set within a range of, for example, 300 mm from both ends of the front surface. The position Te and the position S10 may be matched to omit the section Te, and the pressing force of the side brush 5 may be reduced with respect to the entire front surface. Thereby, when a capacitor | condenser is arrange | positioned at a side edge part, damage to a capacitor | condenser fin can be prevented.

  Further, by increasing the pressing force of the side brush 5 with respect to the front surface of the vehicle CA to be cleaned having a wide vehicle width in the first front surface cleaning mode, it is possible to perform cleaning with high cleaning power.

  According to the present embodiment, the second front surface cleaning mode has a section Tm in which the pressing force of the side brush 5 is smaller than that of the first front surface cleaning mode. For this reason, the front surface of the vehicle CA to be cleaned can be cleaned with high cleaning power in the first front surface cleaning mode, and the capacitor fins can be prevented from being damaged in the second front surface cleaning mode.

  Further, the first front surface cleaning mode is performed when the vehicle width of the vehicle CA to be cleaned is larger than a predetermined value, and the second front surface cleaning mode is performed when the vehicle width is less than the predetermined value. For this reason, the 2nd front washing mode is performed with respect to the small vehicle which a capacitor adjoins to the front, and damage to the capacitor fin of a small vehicle can be prevented.

  Further, the first front surface cleaning mode is performed when the vehicle width of the vehicle CA to be cleaned is larger than 1480 mm, and the second front surface cleaning mode is performed when the vehicle width is smaller. For this reason, the 2nd front washing mode is performed with respect to the light vehicle in which a capacitor is very near to the front, and damage to the capacitor fin of the light vehicle can be prevented. Note that a light vehicle may be determined based on the vehicle length (3400 mm or less) of the vehicle to be cleaned CA detected by the shape sensor 9.

  Further, the vehicle width of the vehicle to be cleaned CA can be easily detected by the pair of distance measuring sensors 11 arranged on the left and right sides of the vehicle to be cleaned CA.

  Further, the pressing force of the side brush 5 is set to be the same as that in the first front surface cleaning mode with respect to the section Te at both side ends of the front surface of the vehicle CA to be cleaned in the second front surface cleaning mode. Thereby, the detergency of both side ends of the front surface of the vehicle CA to be cleaned can be improved.

  Further, a distance D2 between the front surface of the vehicle CA to be cleaned and the rotation center of the side brush 5 in the second front surface cleaning mode in the section Tm is larger than the distance D1 in the first front surface cleaning mode. Thereby, the 2nd front surface washing mode which has section Tm in which the pressing force of side brush 5 is smaller than the 1st front surface washing mode is easily realizable.

<Second Embodiment>
Next, a second embodiment will be described. In the present embodiment, the rotation speed of the side brush is reduced in the second front car wash mode. Other parts are the same as those in the first embodiment.

  In FIG. 4 described above, the rotational speed of the side brush 5 in the first front car wash mode is set to 125 rpm, for example. In the second front car wash mode, the rotational speed of the side brush 5 in the section Tm is set to 100 rpm, for example. That is, the second front surface cleaning mode has a section Tm in which the rotational speed and pressing force of the side brush 5 are smaller than those in the first front surface cleaning mode.

  Thereby, damage to the capacitor fin can be prevented more reliably. The section Tm may be the entire front surface of the vehicle to be cleaned CA.

<Third Embodiment>
Next, a third embodiment will be described. In this embodiment, the positions of the side brushes in the first front car wash mode and the second front car wash mode are the same and the rotational speeds are different. Other parts are the same as those in the first embodiment.

  In FIG. 4 described above, the side brush 5 travels in the path indicated by the solid arrow in the drawing in the first front car wash mode and the second front car wash mode. At this time, the rotational speed of the side brush 5 in the first front car wash mode is set to 125 rpm, for example. In the second front car wash mode, the rotational speed of the side brush 5 in the section Tm is set to 100 rpm, for example. That is, the second front surface cleaning mode has a section Tm in which the rotational speed of the side brush 5 is lower than that in the first front surface cleaning mode.

  Accordingly, as in the first embodiment, the front surface of the vehicle CA to be cleaned can be cleaned with a high cleaning power in the first front surface cleaning mode, and the capacitor fins can be prevented from being damaged in the second front surface cleaning mode. The section Tm may be the entire front surface of the vehicle to be cleaned CA.

<Fourth embodiment>
Next, a fourth embodiment will be described. In this embodiment, the distance measuring sensor 11 (see FIG. 2) is omitted, and the setting items of the remote panel 7 are different from those in the first embodiment. Other parts are the same as those in the first embodiment.

  An item for selecting a light vehicle is displayed on the remote panel 7 (see FIG. 1). Similarly, an item for selecting a light vehicle may be provided on the operation panel 8 (see FIG. 1). When the light vehicle is not selected by operating the remote panel 7 (operation unit), the first front cleaning mode is executed when cleaning the front surface of the vehicle CA to be cleaned. When the light vehicle is selected, the second front cleaning mode is executed when the front surface of the vehicle CA to be cleaned is cleaned. That is, the first front surface cleaning mode and the second front surface cleaning mode are alternatively selected depending on whether or not the light vehicle can be selected by the remote panel 7 (operation unit).

  Thereby, the effect similar to 1st Embodiment can be acquired. Further, since the distance measuring sensor 11 (see FIG. 2) is omitted, the cost of the car wash machine WA can be reduced.

  In the present embodiment, the first front cleaning mode and the second front cleaning mode may be selectable by selecting a predetermined vehicle type without being limited to a light vehicle. Alternatively, the first front surface cleaning mode and the second front surface cleaning mode may be selectable on the remote panel 7 according to the strength of the front surface cleaning power. Similarly, in the second and third embodiments, the first front cleaning mode and the second front cleaning mode may be selectable by operating the remote panel 7 without the distance measuring sensor 11.

<Fifth Embodiment>
Next, FIGS. 5 and 6 are top views showing the operation of the side brush 5 in the first forward path process and the first backward path process of the car wash machine of the fifth embodiment. In this embodiment, the distance measuring sensor 11 (see FIG. 2) is omitted, and the operation of the side brush 5 in the first forward path process and the first backward path process is different from that in the first embodiment. Other parts are the same as those in the first embodiment.

  In the first forward process, as shown in FIG. 5, the side brush 5 disposed at the standby position S <b> 0 is disposed at a position S <b> 2 corresponding to the front end of the car wash machine body 1 by the movement of the car wash machine body 1. When the side brush 5 is arranged at the position S2, the car wash machine main body 1 stops, and the side brush 5 moves in a direction approaching each other and is arranged at the position S10 on the front end of both side surfaces of the vehicle to be cleaned CA.

  Next, the car wash machine body 1 moves toward the rear of the vehicle to be cleaned CA, and the side surface of the vehicle to be cleaned CA is cleaned. At this time, the vehicle width of the vehicle CA to be cleaned is detected by the positions of the left and right side brushes 5. When the side brush 5 is disposed at the position S11 at the rear end of the vehicle CA to be cleaned, the car wash machine main body 1 is stopped, and the side brushes 5 are disposed close to each other at the position S12. Thereby, the rear surface of the vehicle CA to be cleaned is cleaned.

  When the side brush 5 is disposed at the position S12, the first return path step shown in FIG. 6 is performed. In the first return path process, the cleaning water containing the detergent is jetted from the jet nozzle 12 preceding the rotary brush, and the city water is jetted from the jet nozzle 12 following the rotary brush to rinse the detergent.

  The side brush 5 moves away from the position S12 and is disposed at the position S11 at the rear end of the vehicle CA to be cleaned. As a result, the rear surface of the vehicle CA to be cleaned is cleaned again. Next, the car wash machine main body 1 moves toward the front of the vehicle to be cleaned CA, and the side surface of the vehicle to be cleaned CA is cleaned.

  When the side brush 5 is disposed at the position S10 at the front end of the vehicle to be cleaned CA, the car wash machine main body 1 stops, and the side brushes 5 move toward each other. Thereby, the front surface of the vehicle CA to be cleaned is cleaned. At this time, if the vehicle width of the vehicle CA to be cleaned detected in the first outward path process is larger than a predetermined value (1480 mm in the present embodiment), the first front surface cleaning mode is performed. A cleaning mode is performed.

  That is, in the first front surface cleaning mode, the side brush 5 moves in the left-right direction from the position S10 to the position S5. In the second front surface cleaning mode, the side brush 5 moves from the position S10 to the position S7 (see FIG. 4) and stops, and moves to the position S6 (see FIG. 4) by the movement of the car wash machine body 1. Then, the side brushes 5 are moved toward each other and arranged at the position S5 '.

  Next, the side brush 5 moves to the position S1 by the movement of the car wash machine main body 1 and stops, moves in a direction away from each other, and returns to the standby position S0.

  According to this embodiment, the same effect as that of the first embodiment can be obtained. Further, the side surface is cleaned before the front surface of the vehicle CA to be cleaned is cleaned, and the vehicle width is detected based on the position of the side brush 5 at this time. Thereby, since the distance measuring sensor 11 (see FIG. 2) can be omitted, the cost of the car wash machine WA can be reduced. Similarly, in the second and third embodiments, the vehicle width may be detected based on the position of the side brush 5 at the time of side cleaning without the distance measuring sensor 11.

<Sixth Embodiment>
Next, FIG. 7 has shown the front view of the car wash machine main body 1 of 6th Embodiment. In the present embodiment, the distance measuring sensor 11 (see FIG. 2) is omitted, and the image recognition unit 15 is provided in the car wash machine main body 1. Other parts are the same as those in the first embodiment.

  The image recognition unit 15 includes a camera 15a disposed on the entrance surface 1a of the car wash machine body 1, and performs image recognition of an image of the front surface of the vehicle to be cleaned CA acquired by the camera 15a. The image recognizing unit 15 determines a capacitor having a plurality of capacitor fins.

  The distance between the front surface of the vehicle CA to be cleaned and the condenser is detected by the focus position of each camera 15a. Further, the capacitor cannot be recognized if the capacitor is sufficiently away from the front surface of the vehicle CA to be cleaned. Thereby, the capacitor | condenser distribute | arranged within the predetermined distance from the front surface of the to-be-cleaned vehicle CA by the image recognition part 15 is detected. At this time, the horizontal width of the capacitor can be detected by the image recognition unit 15.

  When the car wash is started, the first forward path process and the first backward path process are performed as in the first embodiment. When cleaning the front surface of the vehicle CA to be cleaned, the first front surface cleaning mode and the second front surface cleaning mode are switched based on the detection result of the image recognition unit 15.

  That is, when the capacitor is not disposed within a predetermined distance from the front surface of the vehicle CA to be cleaned, the first front surface cleaning mode is performed, and when the capacitor is disposed within the predetermined distance, the second front surface cleaning mode is performed. In the second front surface cleaning mode, the section Tm (see FIG. 4) is set corresponding to the capacitor width detected by the image recognition unit 15.

  According to this embodiment, the image recognition unit 15 detects a capacitor within a predetermined distance from the front surface of the vehicle CA to be cleaned. Thereby, when a capacitor | condenser adjoins the front surface of the to-be-cleaned vehicle CA, a 2nd front surface washing | cleaning mode can be performed and damage to a capacitor | condenser fin can be prevented. Further, the first front surface cleaning mode is performed when the capacitor is separated from the front surface of the vehicle to be cleaned CA by a predetermined distance, and the front surface of the vehicle to be cleaned CA can be cleaned with high cleaning power.

  Further, since the width of the capacitor can be detected by the image recognition unit 15, the section Tm having a low cleaning power can be set corresponding to the width of the capacitor in the first front surface cleaning mode. Thereby, the detergency of the area | region where a capacitor | condenser is not arranged can be improved.

  In the first to sixth embodiments, the front position of the vehicle CA to be cleaned may be detected by the amount of inclination of the side brush 5 in the front-rear direction when approaching and contacting the front surface of the vehicle CA to be cleaned. At this time, it is more preferable to detect the front position of the vehicle CA to be cleaned and stop the rotation of the side brush 5 until the side brush 5 is arranged at a predetermined cleaning position. Thereby, damage to the capacitor fin can be prevented more reliably.

  ADVANTAGE OF THE INVENTION According to this invention, it can utilize for the car wash machine which wash | cleans the front surface of a to-be-washed vehicle with a side brush.
