Japanese Patent Application Publication No. 2002-59816

The tire cleaning device for a car wash machine described in Patent Document 1 sprays cleaning water onto the tires from a nozzle to clean the tires. The cleaning water diffused from the nozzle may be sprayed onto the car body, and depending on the type of cleaning water, it may stain the car body.

SUMMARY OF THE INVENTION An object of the present invention is to provide a car wash machine that can efficiently apply wash water and liquid to a vehicle to be cleaned while suppressing the scattering of the wash water and liquid and suppressing dirt on the body that is not to be washed and the inside of the car wash. shall be.

In order to achieve the above object, the car wash machine of the present invention includes a car wash main body that moves relative to the vehicle to be washed in the front and back direction, and a car wash machine that is disposed in the main body of the car wash and sprays cleaning water or a liquid agent onto the vehicle to be washed. It has a spray part. The spraying section includes a nozzle that spouts cleaning water or a liquid agent, and a plate member that protrudes toward the vehicle to be cleaned from a tip of the nozzle and guides the jetted cleaning water or liquid agent toward the tire. . The plate member is arranged along the tip of the nozzle, and includes a flat plate portion that becomes narrower toward the tip, and a portion that narrows toward the tip of the flat plate from a direction intersecting the direction in which the nozzle extends toward the nozzle side. It has a rising part that rises up.

According to this configuration, the plate member guides the cleaning water or liquid agent jetted from the spraying part so that it can be sprayed accurately onto the tire. As a result, it is possible to prevent cleaning water or liquid from adhering to the body of the vehicle to be cleaned, and to prevent the body from becoming dirty or dull.

In the car wash machine configured as described above, the plate member is arranged so as to come into contact with the cleaning water or liquid agent jetted from the nozzle. This makes it difficult for the cleaning water or liquid to be sprayed on the outside of the tire, suppresses the adhesion of the cleaning water or liquid to the body of the vehicle being cleaned, and prevents the body from becoming dirty, dull, etc. . Furthermore, since the amount of cleaning water or liquid agent sprayed onto the ground is also reduced, waste of cleaning water or liquid agent can be suppressed.

In the car wash machine configured as described above, the nozzle rotates around the rotation axis, and the plate member rotates around the rotation axis together with the nozzle. This allows cleaning water or liquid to be sprayed all around the tire with a small number of nozzles, and prevents cleaning water or liquid from adhering to the body and staining it, or from being wasted by being sprayed onto the ground. It can be suppressed.

In the car wash machine configured as described above, when the spraying section is viewed from a radial direction perpendicular to the rotation axis, the tip end side of the nozzle is inclined so as to approach the rotation axis, and the plate member has: It is disposed closer to the rotating shaft than the nozzle. With this configuration, the nozzle and the plate member are arranged closer to the central axis, so the spraying section can be downsized.

In the car wash machine configured as described above, the rotating shaft may extend in a direction along the central axis of the tire, and the spraying section may perform a tire cleaning process or a tire coating process.

In the car wash machine configured as described above, the spray section has a plurality of nozzles, and a plurality of plate members are arranged for each of the plurality of nozzles, and the plurality of plate members may be integrally formed. good.

According to the present invention, it is an object of the present invention to provide a car wash machine that can efficiently apply wash water and liquid to a vehicle to be washed while suppressing dirt on the body.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a side view showing a car wash machine 100 according to the present invention. FIG. 2 is a front view of the car wash machine 100 shown in FIG. 1. The car wash machine 100 includes a car wash main body 10 and a rail 60. The car wash main body 10 is formed into a gate shape having two left and right opposing stand parts 10d and a ceiling part 10c connecting the upper ends of the stand parts 10d.

A pair of left and right rails 60 are provided on the ground G, and wheels 10e provided on the bottom surface of the stand portion 10d are arranged on the rails 60. Thereby, the car wash main body 10 is erected on the rails 60, and driven by a travel motor (not shown), the car wash machine main body 10 travels on the rails 60 and moves in the front-rear direction with respect to the vehicle CA to be washed.

It has a remote panel Rp arranged along the approach route to the car wash main body 10. The remote panel Rp has a plurality of buttons and is used to set car wash conditions. Further, an operation panel Cp is arranged on the surface of one stand portion 10d of the car wash machine main body 10 on the entrance surface 10a side. The operation panel Cp can set car wash conditions like the remote panel Rp.

Examples of car wash conditions that can be set using the remote panel Rp and the operation panel Cp include shampooing, waxing, and water-repellent coating. It may also include high quality shampoos, high quality waxes, high quality water repellent coats, special coats, and the like.

The car wash main body 10 is provided with a plurality of rotating brushes that slide on and brush the vehicle CA to be washed. The rotating brushes include a top brush 31, a side brush 32, and a tire brush 33.

The top brush 31 is provided on the ceiling portion 10c so as to be movable up and down, and rotates about a rotating shaft disposed in the left-right direction, thereby cleaning the upper surface of the vehicle CA to be cleaned. The side brushes 32 are provided on the exit surface 10b side of both stand portions 10d so as to be movable in the left and right directions, and rotate on rotating shafts arranged in the vertical direction to clean the front, both side and rear surfaces of the vehicle CA to be cleaned. .

The tire brush 33 is provided at the lower part of both stand parts 10d so as to be movable in the left and right directions, and cleans the outer surface of the tire Ty of the vehicle to be cleaned CA. The tire brush 33 is arranged closer to the entrance surface 10a of the car wash main body 10 than the side brush 32 is. Note that instead of or in addition to the tire brush 33, a rocker brush may be provided for cleaning the lower part of the vehicle CA to be cleaned.

A blower 20 that generates airflow is arranged in the car wash machine main body 10. A plurality of blower nozzles are connected to the blower 20 to send airflow toward the vehicle to be cleaned CA. The ventilation nozzles include a top ventilation nozzle 21 and a side ventilation nozzle 22.

The top blow nozzle 21 is provided on the ceiling portion 10c so as to be movable up and down. The top blower nozzle 21 moves along the top and rear surfaces of the vehicle to be cleaned CA and dries the top and rear surfaces by blowing air. The side blower nozzle 22 is provided on both stand portions 10d so as to be movable back and forth in the left-right direction. The side blower nozzle 22 blows air to dry the side surface of the vehicle CA to be cleaned. At this time, the air from the side air nozzle 22 is also blown onto the tires Ty of the vehicle to be cleaned CA, thereby drying the tires Ty as well. The side blower nozzle 22 is movable in the left and right direction in three stages and four positions. However, the stages of movement are not limited to three stages, and may be more or less than these. Moreover, it may be movable steplessly.

A car-shaped sensor Sr is provided closer to the entrance surface 10a than the top brush 31 of both stand parts 10d of the car wash main body 10. The vehicle shape sensor Sr is composed of a photoelectric sensor, an ultrasonic sensor, etc., and detects the shape of the vehicle to be washed CA entering the car wash main body 10 when projected from the side. Note that the vehicle shape sensor Sr detects the shape of the vehicle and the size of the tire Ty.

The stand portion 10d is provided with a tank storage portion 50 that stores a plurality of liquid storage tanks (not shown) storing various liquid agents such as detergents and coating agents. A distribution piping section 51 for distributing city water and liquid agents from each liquid storage tank is provided above the tank storage section 50. A detergent nozzle 11 and water nozzles 12, 13, and 15 are led out to the distribution piping section 51 via electromagnetic valves (not shown), respectively.

The detergent nozzles 11 are provided at a plurality of locations in the left and right direction of the ceiling portion 10c, and are also provided on both stand portions 10d, although not shown. Further, the detergent nozzle 11 is disposed between the inlet surface 10a and the top brush 31, and sprays an aqueous detergent solution.

The water nozzles 12, 13, and 15 are provided at multiple locations in the left and right direction of the ceiling portion 10c, and are also provided on both stand portions 10d, although not shown. Water nozzle 12 is arranged between detergent nozzle 11 and inlet surface 10a. Water nozzle 13 is arranged between top brush 31 and outlet surface 10b. Water nozzle 15 is arranged between water nozzle 13 and outlet surface 10b.

The water nozzles 12, 13, and 15 spray cleaning water made of city water onto the vehicle CA to be cleaned. The vehicle to be cleaned CA is washed with water using the water nozzles 12, 13, and 15, and the detergent is rinsed with water. Although the car wash machine 100 of this embodiment is configured to wash a vehicle with detergent and city water, it may also be configured to spray a coating agent to coat the surface of the vehicle CA to be cleaned. In this case, the water nozzles 12, 13, and 15 rinse the coating agent with water.

The car wash machine 100 includes a spraying section 40 that performs a tire coating process on the outer surface of the tire Ty of the vehicle CA to be washed. FIG. 3 is an enlarged front view of the spray section 40 and its vicinity. FIG. 4 is an enlarged side view of the vicinity of the spray section 40. As shown in FIG. FIG. 5 is a schematic diagram showing a state in which the tire coating agent Tc is being sprayed from the spraying section 40 toward the tire Ty. FIG. 6 is a front view showing the rotating state of the spray section 40.

As shown in FIGS. 3 and 4, the blowing section 40 is attached to the side blow nozzle 22. As shown in FIGS. The spraying section 40 includes a first nozzle 41, a second nozzle 42, a rotating pedestal section 43, a rotating actuator 44, a moving section 45, and plate members 46a and 46b.

The rotating pedestal portion 43 is attached closer to the entrance surface 10a than the side blow nozzle 22. The rotary pedestal portion 43 is arranged rotatably around a rotation axis Bx that extends in a direction along the central axis Ax of the vehicle to be cleaned CA. Note that the rotation axis Bx extending along the central axis Ax1 includes the case where the rotation axis Bx coincides with the central axis Ax1, and the tire coating agent ejected from the first nozzle 41 and the second nozzle 42 is reliably applied to the tire. This includes cases where the product is misaligned within the range that allows it to adhere to the surface.

A first nozzle 41 and a second nozzle 42 are arranged on the rotating pedestal portion 43 so as to face the outer surface of the tire Ty. As shown in FIGS. 3 and 4, the first nozzle 41 and the second nozzle 42 are arranged at positions equidistant from the rotation axis Bx, that is, directly opposite positions, on opposite sides of the rotation axis Bx. .

The first nozzle 41 and the second nozzle 42 are connected to a distribution piping section 51 and to a tire coating agent storage tank (not shown) accommodated in a tank storage section 50. Further, compressed air is supplied to the first nozzle 41 and the second nozzle 42, and the tire coating agent is ejected at the same time as the compressed air, thereby becoming a mist or foam.

The first nozzle 41 and the second nozzle 42 have the same shape and are arranged rotationally symmetrically about the rotation axis Bx. As shown in FIG. 4, the first nozzle 41 and the second nozzle 42 are inclined so that as they approach the tire Ty, they approach the rotation axis Bx.

Moreover, as shown in FIG. 3, the first nozzle 41 and the second nozzle 42 are inclined toward the rotation direction Rt1 when viewed from the direction of the rotation axis Bx. The direction of inclination may be opposite to the rotation direction Rt1.

When viewed from the entrance surface 10a side, the tire coating agent jetted from the first nozzle 41 is sprayed on the opposite side of the outer surface of the tire Ty across the rotation axis Bx. Similarly, the tire coating agent ejected from the second nozzle 42 is sprayed onto the outer surface of the tire Ty on the opposite side of the rotation axis Bx. Therefore, the length from the tip of each of the first nozzle 41 and the second nozzle 42 to the surface onto which the tire coating agent is sprayed becomes longer.

Thereby, the tire coating ejected from the first nozzle 41 and the second nozzle 42 is sprayed onto the outer surface of the tire Ty in a sufficiently foamed state or a sufficiently atomized state. Therefore, the sprayed tire coating agent is difficult to flow from the outer surface of the tire Ty. Thereby, the tire coating agent can be adhered to the outer surface of the tire Ty.

Usually, in the vehicle to be cleaned CA, a body is arranged above the tires Ty. By increasing the length from the tips of the first nozzle 41 and the second nozzle 42 to the outer surface of the tire Ty to which the tire coating agent adheres, the flow velocity of the tire coating agent when it collides with the tire Ty is reduced. . Therefore, the tire coating agent sprayed on the outer surface of the tire Ty is less likely to splatter, and adhesion to the body can be suppressed.

The rotary actuator 44 rotates the rotary pedestal portion 43 around the rotation axis Bx. Here, it is assumed that the rotating pedestal part 43 rotates in a rotation direction Rt1 in which the upper part of the rotating pedestal part 43 is directed toward the entrance surface 10a side. The rotary actuator 44 is configured to be rotationally driven by air pressure, but is not limited thereto. For example, a configuration using an electric motor may be used.

The moving unit 45 causes the rotary pedestal 43 to reciprocate between a lower position close to the vehicle to be cleaned CA and an upper position away from the vehicle to be cleaned CA. That is, the moving direction of the rotary pedestal section 43 by the moving section 45 forms a constant angle with respect to the ground G. The angle of the moving direction of the rotating pedestal section 43 by the moving section 45 with respect to the ground G may be another angle or may be adjustable. The moving part 45 can be held in a contracted position and an extended position. In other words, the moving section 45 moves the rotary pedestal section 43 to one of two positions and fixes it at that position. However, the present invention is not limited to this, and a moving unit 45 having a configuration that can stop the rotary pedestal 43 at a predetermined position during movement and stably hold the rotating pedestal 43 at that position may be adopted.

Note that, as the moving unit 45, for example, a pneumatic cylinder that expands and contracts with air pressure can be used, but the present invention is not limited to this, and a wide variety of configurations that can reciprocate the rotating pedestal part 43 in the above-mentioned directions can be adopted. The rotating pedestal section 43 is moved in the horizontal direction by the moving section 45 along with the vertical movement. In addition, the moving part 45 may be configured to independently move the rotary pedestal part 43 in the vertical direction and the horizontal direction.

The plate members 46a and 46b are arranged close to the tip 411 of the first nozzle 41 and the tip 421 of the second nozzle 42, respectively. Plate members 46a and 46b arranged close to the first nozzle 41 and the second nozzle 42 are integrally formed via a connecting member 47 (see FIGS. 3 to 6, etc.).

The plate members 46a and 46b are fixed to the rotating pedestal 43 by fixing the connecting member 47 to the rotating pedestal 43 using a fixing device such as a screw. The plate member 46a and the plate member 46b rotate together with the rotating pedestal portion 43 in the rotation direction Rt1. To explain further, the plate member 46a and the plate member 46b rotate in the rotation direction Rt1 about the rotation axis Bx together with the first nozzle 41 and the second nozzle 42, respectively.

Note that the plate members 46a and 46b may be each independently fixed to the connecting member 47. By doing so, it is easy to adjust the angle, position, etc. of the plate members 46a and 46b to suit each nozzle. Alternatively, the connecting member 47 may be omitted, and the plate member 46a and the plate member 46b may be directly fixed to the first nozzle 41 and the second nozzle 42, respectively. Furthermore, the plate member 46a and the plate member 46b may be fixed to the rotary base portion 43.

As shown in FIGS. 3 to 6, a plate member 46a close to the tip 411 of the first nozzle 41 and a plate member 46b close to the tip 421 of the second nozzle 42 have a flat plate portion 461 and a rising portion, respectively. 462. The following description will be made with reference to the plate member 46a that is close to the tip 411 of the first nozzle 41.

The flat plate portion 461 is disposed on the opposite side of the tire Ty with the tip portion 411 of the first nozzle 41 in between when viewed from the direction of the rotation axis Bx. The flat plate portion 461 is arranged along the tip portion 411 of the first nozzle 41 and protrudes in a direction closer to the tire Ty than the tip of the tip portion 411. Then, as it approaches the tire Ty, it is arranged to be inclined so that it approaches the tip 411 of the first nozzle 41. Further, the flat plate portion 461 has a tapered portion 463 that becomes thinner as it approaches the tire Ty.

The rising portions 462 rise toward the tip portion 411 of the first nozzle 41 from both ends of the tapered portion 463 in a direction intersecting the direction in which the tip portion 411 of the first nozzle 41 extends. Note that the rising portion 462 is formed by bending the flat plate portion 461 along the end of the tapered portion 463. However, the present invention is not limited thereto, and the rising portion 462 may be formed separately from the flat plate portion 461 and attached to the flat plate portion 461. Note that the entire flat plate portion 461 may be a tapered portion 463. A rising portion may be formed on a flat plate portion that does not have a tapered portion.

Although details will be described later, the flat plate portion 461 and the rising portion 462 come into contact with the tire coating agent Tc from the tip portion 411 of the first nozzle 41 to correct the jetting direction, in other words, guide the tire coating agent Tc. Further, by providing the rising portion 462, the rigidity of the flat plate portion 461 can be increased, and warpage, twisting, etc. of the flat plate portion 461 can be suppressed. The plate member 46b has the same configuration as the plate member 46a.

The guide of the tire coating agent Tc by the plate member 46a and the plate member 46b will be explained. In FIG. 5, the two-dot chain line indicates the area to which the tire coating agent Tc is sprayed when the plate member 46a and the plate member 46b are not present. As shown in FIG. 5 and the like, in the vehicle to be cleaned CA, the tires Ty are arranged inside a tire house Th formed at the lower part of the body Bd.

In the spray section 40 in the state shown in FIG. 5, the first nozzle 41 located below the rotation axis Bx sprays the tire coating agent Tc toward the upper side of the tire Ty. Further, the second nozzle 42 located above the rotation axis Bx sprays the tire coating agent Tc toward the bottom of the tire Ty.

The tire coating agent Tc ejected from the tip 411 of the first nozzle 41 and the tip 421 of the second nozzle 42 is ejected so as to spread as it approaches the tire. That is, the tire coating agent Tc is diffused from the tip 411 of the first nozzle 41 and the tip 421 of the second nozzle 42 and sprayed onto the tire Ty.

A part of the tire coating agent Tc sprayed from the tip 411 of the first nozzle 41 and diffused comes into contact with the flat plate part 461 and the rising part 462 of the plate member 46a. The tire coating agent Tc that is ejected from the tip 411 of the first nozzle 41 and comes into contact with the flat plate part 461 and the rising part 462 of the plate member 46a flows along the tapered part 463 of the flat plate part 461. The tire coating agent Tc flowing along the flat plate portion 461 is blown out toward the tire Ty from the narrowest tip of the tapered portion 463.

The outer edge of the tire Ty is located on the extension of the surface of the tapered portion 463 that faces the tip 411 of the first nozzle 41. Thereby, the tire coating agent Tc blown out from the tapered portion 463 is sprayed onto the outer edge of the tire Ty. Furthermore, the portion of the tire coating agent Tc ejected from the tip 411 of the first nozzle 41 that does not come into contact with the plate member 46a is directly diffused into a conical shape and is sprayed onto the tire Ty. As described above, by providing the plate member 46a, the tire coating agent Tc ejected from the tip 411 of the first nozzle 41 is not sprayed onto the body Bd, but is accurately sprayed over a wide range of the tire Ty (Fig. (see 5).

The speed of the tire coating agent Tc that has come into contact with the flat plate portion 461 and the rising portion 462 decreases. Therefore, the tire coating agent Tc that collides with the outer edge of the tire Ty collides with the tire Ty at a lower speed than the tire coating agent Tc that is sprayed on the inside of the tire Ty. As a result, the tire coating agent Tc sprayed on the outer edge of the tire Ty is less likely to splatter, and adhesion to the body Bd is suppressed. Note that the inclination of the plate member 46a may be adjusted so that the tire coating agent Tc is sprayed onto the outer edge of the tire Ty in accordance with the jetting speed of the tire coating agent Tc that is decelerated by contact with the flat plate portion 461 and the rising portion 462. good.

Further, as shown in FIG. 5, a plate member 46b is arranged below the tip 421 of the second nozzle 42, which is arranged above the rotation axis Bx. The plate member 46b has the same configuration as the plate member 46a. A portion of the tire coating agent Tc from the tip 421 of the second nozzle 42 that diffuses downward comes into contact with the flat plate portion 461 and the rising portion 462 of the plate member 46b. The tire coating agent Tc that has come into contact with the plate member 46b is guided by the plate member 46b and is sprayed onto the outer edge of the tire Ty. Thereby, it is possible to reduce the tire coating agent Tc sprayed onto the ground G, and it is possible to suppress waste of the tire coating agent Tc.

In the spraying section 40, while the tire coating agent Tc is being sprayed from the tip 411 of the first nozzle 41 and the tip 421 of the second nozzle 42, the rotating pedestal 43 rotates in the rotation direction Rt1 around the rotation axis Bx. For example, rotate by 180 degrees. This prevents the tire coating agent Tc ejected from the tip 411 of the first nozzle 41 and the tip 421 of the second nozzle 42 from adhering to the body Bd of the vehicle CA to be cleaned or spraying onto the ground G. , it is possible to efficiently coat the tire Ty.

In addition, in this embodiment, the spraying part 40 simultaneously sprays the tire coating agent Tc from two nozzles, the first nozzle 41 and the second nozzle 42, and rotates the rotary base part 43 by 180 degrees, thereby spraying the tire coating agent Tc. Tc is sprayed onto the entire tire Ty. However, it is not limited to this. For example, the rotary pedestal section 43 can be made rotatable in both directions around the rotation axis Bx, and when rotating in one direction, the first nozzle 41 and the second nozzle 42 are connected to the tire. The coating agent Tc may be ejected and sprayed onto the tire Ty.

Furthermore, the configuration may include one nozzle, or may include three or more nozzles. In this case, a plate member is placed near the tip of each nozzle.

In the spray section 40 of this embodiment, the tips of the nozzles are inclined so as to approach the rotation axis Bx when viewed from the radial direction perpendicular to the rotation axis Bx, but the invention is not limited thereto. For example, the tip of the nozzle may be inclined away from the rotation axis Bx. As described above, since the nozzle is inclined, by adjusting the position of the spraying section 40 with respect to the tire Ty, it is possible to wash vehicles CA of different sizes.

The car wash machine 100 is capable of washing vehicles of different sizes. FIG. 7 is a diagram showing different sizes of vehicles to be cleaned and the positions of tires. Usually, a large diameter tire Ty1 is mounted on a tire house Th1 disposed at the lower part of a body Bd1 of a large vehicle CA1 to be cleaned. Further, a tire house Th2 disposed at the lower part of the body Bd2 of the small vehicle to be cleaned CA2 has a small diameter tire Ty2.

As shown in FIG. 7, the large vehicle to be cleaned CA1 has a wider width than the small vehicle to be cleaned CA2. Therefore, when the large-diameter tire Ty1 is placed in the car wash 100, the outer surface of the large-diameter tire Ty1 is located closer to the stand portion 10d than the outer surface of the small-diameter tire Ty2.

Therefore, when performing the tire coating process on the large diameter tire Ty1 of the large vehicle to be cleaned CA1, the moving unit 45 is driven to move the spraying unit 40 upwards compared to when performing the tire coating process on the small diameter tire Ty2. At the same time, it is separated from the tire Ty1. By moving in this way, it is possible to spray the tire coating agent Tc ejected from the first nozzle 41 and the second nozzle 42 onto the large diameter tire Ty1. Furthermore, adhesion of the tire coating agent Tc to the outer body Bd1 of the tire house Th1 can be suppressed.

Furthermore, when performing the tire coating process on the small diameter tire Ty2 of the small vehicle to be cleaned CA2, the moving unit 45 is driven to move the spraying unit 40 downward compared to when performing the tire coating process on the large diameter tire Ty1. At the same time, it is brought closer to tire Ty2. By moving in this way, it is possible to spray the tire coating agent Tc ejected from the first nozzle 41 and the second nozzle 42 onto the small diameter tire Ty2. Furthermore, adhesion of the tire coating agent Tc to the outer body Bd1 of the tire house Th1 can be suppressed.

In addition, the spray part 40 is arranged at a neutral position where it does not interfere with the vehicle to be washed CA when washing the car. The neutral position is not particularly limited, but may be, for example, a position between a position where tire coating is applied to a tire with the smallest diameter and a position where tire coating is applied to a tire with the largest diameter. Thereby, the amount of movement of the spray section 40 can be reduced, and the time required for the spray section 40 to move during the tire coating process can be shortened. Therefore, the time required for tire coating treatment can be shortened.

In the car wash machine 100 configured as described above, the user drives the vehicle to be cleaned CA and stops it in front of the remote panel Rp, and sets the car wash conditions for the vehicle to be cleaned from within the vehicle to be cleaned CA. After setting the car wash conditions, the user moves the vehicle to be washed CA to a predetermined washing start position.

By operating the remote panel Rp, the user can select a washing course, a shampoo course, and a tire coating course. In the water washing course, the rotating brush is rotated to spray city water from the water nozzles 12, 13, and 15 to wash the vehicle CA to be washed. In the shampoo course, the rotating brush is rotated to spray washing water containing detergent from the detergent nozzle 11 to wash the vehicle CA to be washed. At this time, city water is sprayed from the water nozzles 12 and 13 to pre-wash the vehicle CA and rinse the detergent. In the tire coating course, similarly to the shampoo course, after cleaning the vehicle CA to be cleaned, a tire coating agent is applied to the outer surface of the tires Ty of the vehicle CA to be cleaned.

FIGS. 8 to 13 are side views showing car washing conditions in the tire coating course. Note that in FIGS. 8 to 13, the moving direction of the car wash machine main body 10 is shown by an arrow, and the direction in which it is moving is shown by a solid line. In addition, when moving after stopping or moving in the opposite direction to the current moving direction in the same operating state, the moving direction is indicated by a dotted line.

When a tire coating course is selected and a car wash is started, the car wash main body 10 moves behind the vehicle to be washed CA (arrow E1) at a predetermined running speed (for example, 5 m/min), as shown in FIG. Then, the first outward step is performed. In the first outgoing step, each rotary brush rotates to clean the front, rear, and upper surfaces of the vehicle CA while the vehicle shape sensor Sr detects the shape of the vehicle CA and the size of the tires Ty.

At this time, detergent wash water S2 is sprayed from the detergent nozzle 11 preceding the top brush 31. Further, city water cleaning water S1 is sprayed from the water nozzle 12 preceding the detergent nozzle 11. As a result, the top brush 31 and the side brushes 32 slide on the body surface of the vehicle CA to be cleaned that has been wetted by the cleaning water S1, and cleaning is performed with the cleaning water S2 containing detergent. Further, the tire brush 33 slides on the outer surfaces of the tire Ty and the foil, and the tire Ty and the foil are cleaned with the cleaning water S2 containing detergent.

In addition, in the first outward step, city water cleaning water S1 is sprayed from the water nozzles 13 and 15 that follow the top brush 31, side brush 32, and tire brush 33. As a result, a portion of the detergent used to clean the vehicle surface of the vehicle to be cleaned CA is washed away.

When cleaning is completed to the rear of the vehicle CA to be cleaned, a first return step is performed in which the car wash main body 10 is reversed and moved to the front of the vehicle CA to be cleaned (arrow E2), as shown in FIG. In the first return step, city water S1 is sprayed from the water nozzles 12, 13, and 15 while the rotary brush rotates. Thereby, rinsing cleaning is performed in which the vehicle surface of the vehicle to be cleaned CA is washed with the cleaning water S1 to wash away the detergent. The first forward step and the first return step are cleaning steps.

When cleaning is completed to the front of the vehicle to be cleaned CA, the first return step is completed and the rotation of the rotating brush is stopped. Then, a second forward step is performed in which the car wash main body 10 is reversed and moved to the rear (arrow E1) of the vehicle to be washed CA.

As shown in FIG. 10, in the second outbound process, the car wash machine main body 10 moves to a position where the tire Ty of the front wheel Wh1 of the vehicle to be washed CA can be coated, and then stops. Note that the position where the coating treatment can be applied to the tire Ty of the front wheel Wh1 is, for example, a position where the position in the front-rear direction of the central axis Ax of the tire Ty of the front wheel Wh1 overlaps with the position in the front-rear direction of the spraying section 40. However, it is not limited to this. In the range of movement, the spray part 40 can widely adopt a position where it can face the tire Ty of the front wheel Wh1 at a constant distance.

Then, as necessary, the side blower nozzle 22 is moved left and right, and the rotating pedestal part 43 is moved by the moving part 45. Thereby, the spray part 40 is arranged at a position where the rotation axis Bx extends along the central axis Ax of the tire Ty of the front wheel Wh1. The first nozzle 41 and the second nozzle 42 face the tire Ty of the front wheel Wh1 at a constant interval (see FIG. 5).

Then, the rotary actuator 44 rotates the rotary base portion 43 in the rotation direction Rt1, and the tire coating agent Tc is sprayed onto the outer surface of the tire Ty from the first nozzle 41 and the second nozzle 42. By rotating the rotating base portion 43 by 180 degrees, the tire coating agent Tc is sprayed all over the outer circumference of the tire Ty of the front wheel Wh1.

After the coating of the tire Ty of the front wheel Wh1 is completed, the ejection of the tire coating agent Tc from the first nozzle 41 and the second nozzle 42 is stopped. Then, the car wash main body 10 resumes moving the vehicle CA to be washed backward. When the car wash main body 10 moves, if the first nozzle 41 and the second nozzle 42 interfere or are likely to interfere with the vehicle to be washed CA, the moving part 45 and the side blower nozzle 22 are operated as necessary. Then, the spray section 40 is separated from the vehicle to be cleaned CA. When the car wash main body 10 moves, the spray section 40 may always be moved away from the vehicle to be washed CA, for example, to a neutral position.

As shown in FIG. 11, in the second outbound process, the car wash machine main body 10 moves to a position where the coating process can be performed on the tire Ty of the rear wheel Wh2 of the vehicle to be washed CA, and then stops. Note that the position where the coating process can be applied to the tire Ty of the rear wheel Wh2 is set in the same way as the position where the coating process can be applied to the tire Ty of the front wheel Wh1.

Then, the tire coating process is performed on the tire Ty of the rear wheel Wh2 in the same manner as the coating process of the tire Ty of the front wheel Wh1 described above. After the tire coating process for the tire Ty of the rear wheel Wh2 is completed, the spraying of the tire coating agent Tc from the first nozzle 41 and the second nozzle 42 is stopped, and the spraying section 40 is moved as necessary. Then, the car wash main body 10 moves to the rear of the vehicle CA to be washed. When the car wash main body 10 moves to the rear of the vehicle to be washed CA, the second outbound process ends.

Thereafter, a second return step is performed in which the car wash machine main body 10 is reversed and moved forward (arrow E2) of the vehicle to be washed CA. In the second return step, the car wash main body 10 moves to a position where the tire Ty of the rear wheel Wh2 can be coated and stops (see FIG. 11). Then, in the same procedure as described above, the car wash main body 10 performs a tire coating process on the tire Ty of the rear wheel Wh2 of the vehicle to be washed CA. After finishing the tire coating process on the rear wheel Wh2, the car wash main body 10 resumes forward movement of the vehicle CA to be washed.

Thereafter, the car wash main body 10 moves to a position where the tire Ty of the front wheel Wh1 can be coated and stops (see FIG. 10). Then, in the same procedure as described above, the car wash main body 10 performs a tire coating process on the tire Ty of the front wheel Wh1 of the vehicle CA to be washed. After finishing the tire coating process on the front wheel Wh1, the car wash main body 10 resumes moving the vehicle CA to be washed forward. When the car wash main body 10 moves forward of the front of the vehicle CA to be washed, the second return step ends.

The second outbound process and the second return process are tire coating processes. In the tire coating course of the car wash main body 10, the tire coating process is performed twice on each of the tires Ty of the front and rear wheels. Although the car wash main body 10 is moved to the rear of the vehicle to be washed CA at the end of the second outgoing process, the present invention is not limited thereto. For example, after a certain period of time has passed after the tire coating process of the tire Ty of the rear wheel Wh2 is completed, the tire coating process of the tire Ty of the rear wheel Wh2 is performed again, and then the car washing machine main body 10 is moved in front of the vehicle CA to be washed. A second return step of moving may be performed. In addition, before spraying the tire coating agent Tc onto the tire Ty, a partial drying step of drying the tire Ty by spraying an air flow onto the tire Ty may be included.

After the second return step is completed, as shown in FIG. 12, a third outward step is performed in which the car wash main body 10 is reversed and moved to the rear of the vehicle CA to be washed (arrow E1). In the third outward step, city water cleaning water S1 is sprayed from the water nozzles 12, 13, and 15. This performs a rinsing process to spread the tire coating agent. Note that at this time, the cleaning water S1 is also sprayed on the top and side surfaces of the vehicle to be cleaned CA to wash away the remaining detergent and the tire coating agent Tc that has adhered to the surface of the vehicle to be cleaned CA.

In addition, in the third outgoing process, a third returning process is performed in which the car wash machine main body 10 that has reached the rear surface of the vehicle to be cleaned CA is reversed and moved to the front (arrow E2) of the vehicle to be cleaned CA. At this time, in the third return step, city water cleaning water S1 is injected from the water nozzles 12, 13, and 15, as in the third outward step. Note that when switching from the third forward step to the third return step, the injection of the cleaning water S1 from the water nozzles 12, 13, and 15 may be stopped. The third return process and the third outward process are, for example, a tire coating agent rinsing process in which unnecessary tire coating agent Tc adhering to the body surface of the vehicle to be cleaned CA, excessive tire coating agent Tc adhering to the tires Ty, etc. are washed away. It is.

After the third return step is completed, as shown in FIG. 12, a fourth outward step is performed in which the car wash machine main body 10 is reversed and moved to the rear of the vehicle CA to be washed (arrow E1). In the fourth outward step, the air flow K1 is sent out from the top blow nozzle 21 and the side blow nozzle 22 to dry the vehicle CA to be cleaned. In other words, the second forward step forms a drying step. In the fourth outward step, the tire coating agent Tc sprayed on the outer surface of the tire Ty is also dried. Thereby, the tire coating agent Tc can be stably fixed on the outer surface of the tire Ty.

As described above, in the car wash machine 100, after cleaning the tires Ty of the vehicle to be cleaned CA, the tire coating agent Tc is applied to the outer surface of the tires Ty. Then, the tire coating agent Tc is fixed on the outer surface of the tire Ty by blowing an air flow onto the outer surface of the tire Ty to which the tire coating agent Tc has been applied and drying it. Thereby, when the vehicle to be cleaned CA is washed by the car wash machine 100, it is possible to perform the tire coating process on the outer surface of the tire Ty.

Although the above description describes a configuration in which the tire coating agent Tc is sprayed onto the tire Ty, that is, a tire coating process is performed, the present invention is not limited thereto. For example, a configuration may be adopted in which cleaning water containing detergent is sprayed from the spraying section 40, or a configuration in which cleaning water formed from city water is sprayed. In the case of the configuration in which cleaning water containing detergent is sprayed or the configuration in which cleaning water formed from city water is sprayed, the area to which the cleaning water is sprayed is not limited to the tire Ty.

Although the embodiments of the present invention have been described above, the present invention is not limited thereto. Further, the embodiments of the present invention can be modified in various ways without departing from the spirit of the invention.
