Japanese Patent Application Publication No. 2002-59816

The tire cleaning device for a car wash machine described in Patent Document 1 switches a plurality of nozzles to spray cleaning water according to the size of the tire. However, when preparing nozzles according to the tire size, the number of nozzles increases, the piping becomes complicated, and the car wash machine becomes larger.

SUMMARY OF THE INVENTION An object of the present invention is to provide a car wash machine that can efficiently apply tire coating to the tires of a vehicle to be washed while suppressing the increase in size.

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 a vehicle to be washed in the front and back direction, and a car wash machine disposed in the main body of the car wash to apply a tire coating agent to the tires of the vehicle to be washed. It has a spraying part for spraying. The spraying section is capable of applying the tire coating agent to N locations (N is an integer of 2 or more) on the tire. The tire rotates at (360/N) degrees in one direction and in a second direction opposite to the first direction, and when rotating in the first direction and in the second direction, the tire is different. Spray the tire coating agent onto the area.

According to this configuration, the tire coating agent is applied to different regions of the tire when the spraying section reciprocates around the rotation axis. Therefore, the tire coating agent can be applied to the tire in just the right amount. Moreover, the simultaneous supply amount of compressed air required for jetting out the tire coating agent can be suppressed. As a result, the maximum supply amount of compressed air can be suppressed, the tire coating agent can be effectively sprayed onto the tires even with a small compressor, and the size of the car wash machine can be suppressed.

In the car wash machine configured as described above, the spraying section includes a first nozzle and a second nozzle that spray the tire coating agent, and the first nozzle and the second nozzle are rotationally symmetrical about the rotation axis. When the spray section rotates 180 degrees in the first direction, the first nozzle sprays the tire coating agent, and when the spray section rotates 180 degrees in the second direction, the second nozzle sprays the tire coating agent. Squirt out the tire coating. As a result, since the tire coating agent is alternately ejected from the nozzles one by one, the amount of compressed air required to eject the tire coating agent per unit time can be suppressed, and the size of the car wash machine can be suppressed.

The car wash machine configured as described above includes a moving part that moves the spraying part so that the tire coating agent is sprayed at a predetermined position on the tire. According to this configuration, the tire coating agent is sprayed from an appropriate position, which prevents the tire coating agent from being sprayed on areas other than the tire, or from splashing when it hits the tire, and from adhering to parts other than the tire (for example, the body). can.

In the car wash machine configured as described above, the moving section moves the spraying section in the vertical direction so that the rotation axis of the spraying section approaches the central axis of the tire. Further, the moving section moves the spraying section in a direction along the rotational axis so that the spraying section and the tire face each other in the rotational axis direction with a predetermined interval. With this configuration, it is possible to accommodate tires of different sizes. Furthermore, since the distance between the side surface of the vehicle to be cleaned and the spraying section can always be kept constant, the tire coating agent can be sprayed substantially uniformly onto the tires.

In the car wash machine configured as described above, the moving unit may reciprocate the spraying unit between a lower position close to the vehicle to be washed and an upper position away from the vehicle to be washed.

The car wash machine configured as described above may further include a side blower nozzle arranged on the car wash main body and movable in the left-right direction, and the moving part may be attached to the side blower nozzle.

In the car wash machine configured as described above, the movement of the side blower nozzle in the left-right direction and the movement of the blowing part by the moving part may be performed independently.

In the car wash machine configured as described above, the first nozzle and the second nozzle may be inclined such that their tip ends approach the rotation axis. The first nozzle and the second nozzle may be inclined such that their tip ends face in the same circumferential direction around the rotation axis.

According to the present invention, it is possible to efficiently coat the tires of a vehicle to be cleaned while suppressing the increase in size.

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 brush around 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. The blowing section 40 is attached to the side blowing nozzle 22. The spraying section 40 includes a first nozzle 41 , a second nozzle 42 , a rotating pedestal section 43 , a rotating actuator 44 , and a moving section 45 .

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 first direction Rt1 when viewed from the rotation axis Bx direction. The direction of inclination may be opposite, that is, it may be inclined toward the second direction Rt2.

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.

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 difficult to splash, and adhesion of the tire coating agent to the body, wheels, brakes, and tire house of the vehicle to be cleaned CA can be suppressed.

The rotary actuator 44 rotates the rotary pedestal portion 43 in both directions around the rotation axis Bx. Note that, regarding the rotation direction of the rotary pedestal section 43, the direction in which the upper part of the rotary pedestal section 43 goes toward the entrance surface 10a side is a first direction Rt1, and the direction toward the exit surface 10b side is a second direction Rt2. That is, the first direction Rt1 and the second direction Rt2 are circumferential directions around the rotation axis Bx, and are opposite to each other. 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 at an upper position and a lower 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 blowing section 40 can be moved in the left-right direction to three stages and four positions by moving the side blowing nozzle 22, and can be moved to two positions by the moving section 45. In other words, the spray section 40 is movable to eight different positions in height and in the left-right direction. By changing the movable position of at least one of the side blower nozzle 22 and the moving part 45, the possible positions of the blowing part 40 can also be changed.

Note that the movement of the side blower nozzle 22 in the left-right direction and the movement of the moving part 45 in the up-down direction are performed independently of each other. Therefore, the spray section 40 can be moved independently in the left-right direction and the up-down direction. As a result, for example, the lowest point is reached when all four corners are at 90 degrees, and a link mechanism using a parallelogram-shaped link frame that moves in conjunction with the vertical direction as it moves in the left and right direction can be used. Compared to the case where the spraying section 40 is moved by moving the spraying section 40, the degree of freedom in the positions that the spraying section 40 can take is increased.

Thereby, the spraying unit 40 can accurately spray the tire coating agent at a predetermined position on the tire Ty. Here, the predetermined position of the tire Ty is the outer surface of the tire Ty excluding the tire wheel. That is, since the spray unit 40 sprays accurately onto predetermined positions of the tire Ty, when performing tire coating processing on the tire Ty, it suppresses the adhesion of the tire coating agent to the body, wheels, brakes, and tire house of the vehicle to be cleaned CA. can.

In addition, although the moving unit 45 is configured to be moved from above to below so that the rotation axis Bx of the spraying unit 40 approaches the central axis Ax of the tire Ty, it may be configured so that it can approach from below to above. . By doing so, even if the rotation axis Bx of the spray section 40 deviates downward from the center axis Ax, it is possible to suppress the tire coating agent from adhering to the body of the vehicle CA to be cleaned.

The car wash machine 100 is capable of washing vehicles CA of different sizes. FIG. 5 is a diagram showing different sizes of vehicles to be cleaned and the positions of tires. Usually, large-diameter tires Ty1 are mounted on the large-sized vehicle CA1 to be cleaned. Moreover, the small-sized vehicle to be cleaned CA2 has small-diameter tires Ty2.

As shown in FIG. 5, 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. Moreover, the center axis Ax1 of the large diameter tire Ty1 is located above the center axis Ax2 of the small diameter tire Ty2.

Therefore, by moving the rotating pedestal part 43 upward and in a direction approaching the stand part 10d by the moving part 45, the first nozzle 41 and the second nozzle 42 are made to face the outer surface of the large-diameter tire Ty1, and the rotating pedestal part 43 is moved upward and toward the stand part 10d. The rotation axis Bx of the portion 43 extends along the central axis Ax1 of the large diameter tire Ty1. This makes it possible to perform a tire coating process in which the tire coating agent is sprayed at a predetermined position on the large diameter tire Ty1.

Similarly, by moving the rotary base part 43 downward and away from the stand part 10d by the moving part 45, the first nozzle 41 and the second nozzle 42 are made to face the outer surface of the small diameter tire Ty2, and the rotary base part 43 is moved downward and away from the stand part 10d. The rotation axis Bx of the portion 43 extends along the central axis Ax2 of the small diameter tire Ty2. This makes it possible to perform a tire coating process in which the tire coating agent is sprayed at a predetermined position on the small diameter tire Ty2.

Further, when cleaning a vehicle to be cleaned whose size is between the large vehicle to be cleaned CA1 and the small vehicle to be cleaned CA2, by stopping the rotary pedestal section 43 in the middle of movement by the moving section 45, The tire coating process can be performed similarly to the large vehicle to be cleaned CA1 and the small vehicle to be cleaned CA2.

Further, the position of the vehicle to be cleaned CA in the left-right direction with respect to the car wash machine 100 may deviate from a previously assumed position. In this case, the position of the tire Ty in the left-right direction also deviates from a predetermined position. In such a case, the distance between the first nozzle 41 and the second nozzle 42 and the outer surface of the tire Ty can be adjusted by moving the side blower nozzle 22. With this configuration, if the position of the vehicle to be cleaned CA shifts in the left-right direction, or if the tire Ty of the vehicle to be cleaned CA is equipped with tires Ty that are larger or smaller than the expected size, The tire coating process can also be performed accurately.

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.

Next, the tire coating process performed on the tire Ty by the spraying section 40 will be described. FIG. 6 is a diagram showing a state in which the tire coating agent is being sprayed from the first nozzle 41. FIG. 7 is a diagram showing a state in which the tire coating agent is being sprayed from the second nozzle 42. In addition, in FIG. 6, FIG. 7, it is set as tire coating agent CL, and is demonstrated as tire coating agent CL.

As shown in FIGS. 6 and 7, in the spray section 40, a first nozzle 41 and a second nozzle 42 are arranged at intervals of 180 degrees in the circumferential direction. A state in which the first nozzle 41 and the second nozzle 42 are vertically aligned and the first nozzle 41 is disposed below the second nozzle 42 is the initial rotation position. Further, the portion of the tire coating agent CL jetted from the first nozzle 41 and the second nozzle 42 that contacts the tire Ty is defined as a spray region Sp.

The spray unit 40 sprays the tire coating agent CL from the first nozzle 41 while rotating from the initial rotation position to the reverse position rotated by 180 degrees in the first direction Rt1. As a result, the spraying area Sp where the tire coating agent CL of the tire Ty is sprayed starts from the first spraying area Sp1 at the upper part of the entrance surface 10a side of the tire Ty, passes through the entrance surface 10a side of the tire Ty, and passes through the tire Ty on the entrance surface 10a side. (see FIG. 6).

Further, the spraying section 40 sprays the tire coating agent CL from the second nozzle 42 while rotating from the reverse position to the initial position in the second direction Rt2. As a result, the spraying area Sp where the tire coating agent CL of the tire Ty is sprayed starts from the first spraying area Sp1 at the upper part of the entrance surface 10a side of the tire Ty, passes through the exit surface 10b side of the tire Ty, (see FIG. 7).

By doing so, it is possible to accurately apply the tire coating agent CL over the entire circumference of the outer surface of the tire Ty. Since the first nozzle 41 and the second nozzle 42 operate alternately, the amount of compressed air supplied at the same time can be reduced. Therefore, the amount of compressed air required per unit time can be reduced, so the compressor that generates compressed air can be downsized, and the car wash machine 100 itself can be downsized. Moreover, the maximum discharge amount of compressed air by the compressor can be suppressed, and energy consumption can be reduced.

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).

The rotary actuator 44 rotates the rotary base portion 43 in the first direction Rt1, and the tire coating agent is sprayed from the first nozzle 41 onto the outer surface of the tire Ty of the front wheel Wh1. After the rotating pedestal part 43 rotates 180 degrees, the rotating pedestal part 43 is reversed in the second direction Rt2, and the tire coating agent is sprayed from the second nozzle 42 onto the outer surface of the tire Ty of the front wheel Wh1. As a result, the tire coating agent 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 jetting of the tire coating agent 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, at least one of the side blower nozzle 22 and the moving part 45 is operated. 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 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. Further, in the present embodiment, the Ty tire coating agent is sprayed in the second return step as well, but the present invention is not limited to this, and the tire Ty may be rinsed by spraying cleaning water. Also in this case, the second return step is a tire coating step. Note that, before spraying the tire coating agent onto the tire Ty, a partial drying step may be included in which the tire Ty is dried by spraying an air flow onto the tire Ty.

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 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 adhering to the vehicle body surface of the vehicle to be cleaned CA, excessive tire coating agent adhering to the tires Ty, etc. are washed away. .

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 sprayed on the outer surface of the tire Ty is also dried. Thereby, the tire coating agent 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, a tire coating agent is applied to the outer surface of the tires Ty. Then, the tire coating agent 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 is 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.

In addition, in the spraying section 40 of this embodiment, the tire coating agent is sprayed from the first nozzle 41 and the second nozzle 42. At this time, in order to prevent the tire coating agent from adhering to parts other than the outer surface of the tire Ty, a guide member may be attached to control the direction in which the tire coating agent is sprayed. Thereby, it is possible to suppress the tire coating agent from adhering to the body, wheels, brakes, etc. of the vehicle CA to be cleaned. Note that the guide member is disposed closer to the rotation axis Bx than the first nozzle 41 and the second nozzle 42, that is, on the inside in the radial direction.

In the car wash machine 100 of the present embodiment, the spray section 40 has a configuration in which each of the first nozzle 41 and the second nozzle 42 is provided, but the present invention is not limited to this. For example, there may be a plurality of at least one of the first nozzle 41 and the second nozzle 42. In this case, all the nozzles are arranged on the rotary pedestal portion 43 at equal intervals in the circumferential direction around the rotation axis. When the total number of nozzles is N (N>2), the rotating pedestal 43 rotates (360/N) in the first direction Rt1, and all the first nozzles simultaneously eject the tire coating agent. Thereafter, it also rotates in the second direction Rt2 (360/N), and at the same time the second nozzle jets out the tire coating agent. By doing so, the tire coating agent can be applied to the entire circumference of the outer surface of the tire without excess or deficiency.

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.
