  In addition, the first tension adjustment unit 336 moves the motor 330 and the output sprocket 331 along the standing frame 12. In addition, movement is moved by a screw. Thus, when the first chain 334 is extended, the distance between the output sprocket 331 and the transmission sprocket 332 is adjusted, and the slack of the first chain 334 is suppressed. Similarly, the second tension adjustment unit 337 moves the sprocket support frame 13 along the lower frame 11. Thereby, the distance between the rotation shaft of the transmission sprocket 332 and the rotation shaft (axle 52) of the drive sprocket 333 is adjusted, and the slack of the second chain 335 is suppressed.

  When the output sprocket 331 is rotated by the output from the drive of the motor 330, the rotation (rotational force) of the output sprocket 331 is transmitted to the first gear portion 332a of the transmission sprocket 332 via the first chain 334. Thus, the transmission sprocket 332 rotates. The rotation of the transmission sprocket 332 rotates the second gear portion 332 b, and the rotation (rotational force) is transmitted to the drive sprocket 333 via the second chain 335.

  That is, the power of the motor 330 is transmitted to the output sprocket 331, the first chain 334, the transmission sprocket 332, the second chain 335 and the drive sprocket 333. Then, by the power of the motor 330, the drive wheel 31 to which the drive sprocket 333 is fixed rotates. In the present embodiment, the power of the motor 330 is transmitted to the drive wheel 31 via the transmission sprocket 332, but the invention is not limited thereto. For example, the output sprocket 331 and the drive sprocket 333 may be connected by one chain.

<About the operation of the car wash machine WA>
The operation of the above-described car wash machine WA according to the present invention will be described. In the car wash machine WA, the car wash machine main body 10 is operated based on the operation of the operation panel (not shown) by the operator. When passing through the vehicle to be cleaned CA, the car wash machine body 10 operates the cleaning unit, the brushing unit and the drying unit to clean the vehicle to be cleaned CA including washing, drying, water repellent coating, waxing, etc. I do.

  In the vehicle to be cleaned CA, there are places where it is difficult to clean the car wash machine 10, such as the lower surface (hereinafter referred to as the lower side). For cleaning of the lower part of the vehicle to be cleaned CA and the like, a worker sprays water (for example, high-pressure water) with a hose or the like to perform hand washing and cleaning. Hand washing is often performed in the vicinity of the car wash WA, and after the hand washing is finished, the hose HS may be left on the rail 20 when the vehicle wash is performed by the car wash WA. . In the car wash machine WA, when the car wash machine main body 10 approaches the vehicle to be cleaned CA, the article exclusion unit 40 avoids (eliminates) the hose HS, so that the crossing of the drive wheel 31 and the hose HS is suppressed.

  Here, the removal operation of the hose HS (article) by the article exclusion unit 40 will be described. As described above, the article contact surface 43 of the article exclusion unit 40 is provided on the outer side in the first direction D1, ie, the moving direction of the car wash machine body 10, than the contact portion 310 contacting the rail 20 of the drive wheel 31. . Therefore, when the car wash machine body 10 moves the drive wheel 31 forward, the article contact surface 43 first contacts the hose HS on the rail 20. The article contact surface 43 is an inclined surface having a lower end portion located below the upper end portion of the rail 20 and approaching the axle shaft 52 as it goes upward. Therefore, the lower end portion of the article contact surface 43 dives into the lower portion of the hose HS. Further, when the article contact surface 43 pushes the hose HS, the hose HS is pushed from the article contact surface 43 in the direction along the rail 20 and pushed up upward. Thus, the hose HS can be prevented from being pinched between the rail 20 and the drive wheel 31. Then, when the car wash machine body 10 moves on the rail 20 to the end, the hose HS is removed from the rail 20.

  For example, when using a resin-made soft hose HS for hand washing, it is possible to prevent the hose HS from being cut by being pinched between the drive wheel 31 and the rail 20. In addition, when using a high-strength hose HS with metal reinforcement that spouts high-pressure water, the driving wheel 31 rides on the hose HS to remove the wheel of the car wash machine main body 10 and the driving wheel 31 (wheel) and The deformation of the rail 20 can be suppressed. Also, since the hose HS is pushed upward by the article contact surface 43, the friction between the hose HS and the rail 20 can be reduced. Also from this point, it is possible to suppress the deterioration such as the wear of the hose HS and / or the rail 20.

  In the car wash machine main body 10 according to the present embodiment, the rails 20 are arranged on both outer sides of the second direction D2 side by side, and the article removing unit 40 is arranged side by side. The movement of the hose HS to the contact portion 310 between the drive wheel 31 and the rail 20 can be suppressed. In the car wash machine main body 10, the article exclusion unit 40 and the rail 20 are disposed so as not to overlap vertically. Therefore, for example, even if the outer diameter of the drive wheel 31 is reduced due to wear or the like, and the gap between the lower frame 11 and the floor portion FL is reduced, the contact between the article removing unit 40 and the rail 20 is suppressed.

  Furthermore, the article exclusion unit 40 disposed so as to sandwich the rail 20 is disposed more outward from the rail 20 than the end of the stopper 24 in the second direction D2 in the second direction D2. Therefore, even if the drive wheel 31 contacts the stopper 24, the drive wheel 31 does not easily contact the stopper 24 of the article removal unit 40, and deformation or the like of the holding plate unit 514 to which the article removal unit 40 or the article removal unit 40 is fixed can be suppressed.

  In the car washer WA, the hoses HS (articles) on the rail 20 are pushed along the rail 20 by the article exclusion unit 40. At this time, the hose HS is pushed up by the article contact surface 43. At this time, if the angle of the article contact surface 43 with respect to the rail 20 is small, the hose HS may exceed the upper end of the article contact surface 43. Therefore, it is preferable that the angle of the article contact surface 43 be an angle such that the article does not exceed the upper end. To explain further, the angle of the article contact surface 43 is determined by the moving speed of the car wash machine body 10, the assumed weight of the article, and the like. In the present embodiment, the angle of the article contact surface 43 is about 75 degrees with respect to the rail 20, but is not limited thereto.

  In addition, although the car wash machine main body 1 moves with respect to the to-be-cleaned vehicle CA which has stopped in the car wash machine WA of this embodiment, it is not limited to this. For example, on the floor surface, a moving mechanism such as a belt conveyor may be provided to move both the vehicle to be cleaned CA and the car wash machine body 1.

  The article exclusion unit 40 is a plate-like member, and also serves as a key for locking the axle 52. Therefore, the key portion 42 of the article exclusion unit 40 has a thickness capable of being inserted into the key groove 521 of the axle 52 and a through hole capable of inserting the fastener Bt2 so that it can be attached to the conventional car wash machine main body is there. From this, the car wash machine main body used in the car wash machine according to the present invention is a simple operation and structure change such as replacing the key of the wheel holding unit of the conventional car wash machine main body with the article removing unit 40 Specification change is possible. This saves time for design and reduces waste.

In the car wash machine main body 10, the article removing unit 40 is fixed to the holding plate portion 514 of the wheel holding unit 50 holding the driving wheel 31, and is also fixed to the holding plate portion 614 of the wheel holding unit 60 holding the driven wheel 32. You may As described above, by attaching the article removing unit 40 to the driven wheel 32, the car wash machine main body 10 moves in the direction away from the vehicle to be cleaned CA, more specifically, also when moving to the driven wheel 32 side. Articles on 20 can be eliminated. In the article exclusion unit 40 attached to the holding plate unit 614 of the wheel holding unit 60, the obstacle portion 41 is disposed outside the car wash machine body 10 in the direction away from the axle 62, that is, in the first direction D1. . In other words, the relief portion 41 of the article exclusion unit 40 attached to the holding plate portion 514 and the relief portion 41 of the article exclusion unit 40 attached to the holding plate portion 614 are opposite to each other in the first direction D1. It is the direction.

  In the present embodiment, after the hose HS, which is an article, comes into contact with the article contact surface 43, the hose HS is pushed to the end of the rail 20 in the first direction D1 and removed from the rail 20. However, it is not limited to this. For example, the article contact surface 43 of the inner article exclusion unit 40 is projected to the outside of the first direction D1 relative to the article contact surface 43 of the outer article exclusion unit 40, and the articles in the rail 20 are You may make it move outside. In addition, a detection device such as a sensor may be attached, and when it is detected that an article is in contact with the article contact surface 43, an alarm such as a buzzer may be issued. At this time, the movement of the car wash machine main body 10 may be stopped.

Second Embodiment
Another example of a car wash machine body used for a car wash machine according to the present invention will be described with reference to the drawings. FIG. 8 is a schematic view showing another example of a car wash main body used for the car wash according to the present invention. The car wash machine main body 10B described in the present embodiment has the same configuration as the car wash machine main body 10 of the first embodiment except that the article exclusion unit 40B is different from the article exclusion unit 40. Therefore, in the car wash machine main body 10B, parts substantially the same as the car wash machine main body 10 are denoted by the same reference numerals, and detailed description of the same parts is omitted.

  As shown in FIG. 8, the article removing unit 40 </ b> B includes a relief portion 41 that protrudes to both sides of the key portion 42 in the first direction D <b> 1. With such a configuration, as in the first embodiment, when there is an article outside the first direction D1 of the car wash machine body 10B, breakage of the article or removal of the car wash machine body 10B due to the article, car wash The deformation, breakage and the like of the machine body 10B and the rail 20 can be suppressed. Also, for example, in a state where the article intrudes into a portion between the drive wheel 31 and the driven wheel 32 of the car wash machine main body 10B, the article is the rail 20 even when the car wash machine main body 10B moves in the direction away from the vehicle to be cleaned CA. It is possible to suppress pinching between the drive wheel 31 and the drive wheel 31.

  As a result, it is possible to prevent the article from being pinched and broken between the rail 20 and the drive wheel 31 of the car wash machine main body 10B. In addition, it is possible to prevent the article from being caught between the rail 20 and the drive wheel 31 and the drive wheel 31 from derailing. The same effect can be obtained when the driven wheel 32 is attached.

  From the above, in the car wash machine main body 10B according to the present embodiment, the articles are the wheels (the driving wheels 31 and / or the driven wheels 32) and the rails 20 regardless of the moving direction of the car wash machine main body 10B and the positions of the articles. It can suppress being caught.

Third Embodiment
The further another example of the car-washing machine main body used for the car-washing machine concerning this invention is demonstrated with reference to drawings. FIG. 9 is an enlarged view of the periphery of the drive wheel of the car wash machine body used in the car wash machine according to the present invention. The car wash machine main body 10C shown in FIG. 9 has the same configuration as the car wash machine main body 10 of the first embodiment except that the article removing unit 40C is different. Therefore, in the car wash machine main body 10C, parts substantially the same as the car wash machine main body 10 are denoted by the same reference numerals, and detailed description of the same parts is omitted.

  As shown in FIG. 9, the article exclusion unit 40 </ b> C of the car wash machine main body 10 </ b> C includes an article contact surface 43 </ b> C at the tip of the obstruction portion 41. The article contact surface 43C has a curved shape in which a central portion in the vertical direction is recessed toward the axle. Thus, by making the article contact surface 43C into a curved shape, the angle of the article contact surface 43C with respect to the floor portion FL is smaller at the lower portion and larger at the upper portion. Therefore, the article contact surface 43C can lift the hose HS upward even if the moving speed is low. In addition, when the moving speed is high and the hose HS contacts the upper portion of the article contact surface 43C, the inclination of the contact portion of the article contact surface 43C with the hose HS with respect to the floor portion FL is large. As a result, the upward force that the hose HS receives from the article contact surface 43C is reduced, and it is possible to suppress the hose HS from moving above the upper end of the article contact surface 43C.

  In the car wash machine main body 10C according to the present embodiment, even if the speed of the car wash machine main body 10C changes, it is possible to efficiently remove an article such as the hose HS mounted on the rail 20.

  The other features are the same as those of the first and second embodiments.

Fourth Embodiment
The further another example of the car-washing machine main body used for the car-washing machine concerning this invention is demonstrated with reference to drawings. FIG. 10 is an enlarged view of the periphery of the drive wheel of the car wash machine used in the car wash according to the present invention. The car wash machine main body 10D shown in FIG. 10 has the same configuration as the car wash machine main body 10 of the first embodiment except that the article removing unit 40D is different. Therefore, in the car wash machine main body 10D, parts substantially the same as the car wash machine main body 10 are denoted by the same reference numerals, and detailed description of the same parts is omitted.

  As shown in FIG. 10, the article exclusion unit 40D of the car wash machine main body 10D includes an article contact surface 43D at the tip of the obstruction portion 41. The article contact surface 43D includes a first inclined surface 431 that is inclined to approach the axle 52 as it goes upward from the lower end. Further, the article contact surface 43D is provided with a second inclined surface 432 inclined so as to approach the axle shaft 52 as it goes downward from the upper end. Further, the article contact surface 43 </ b> D includes a connection surface 430 connected to the upper end of the first inclined surface 431 and the lower end of the second inclined surface 432.

  In the article contact surface 43D, the upper end is closer to the axle 52 than the lower end. By forming in this manner, the lower side of the second inclined surface 432 vertically opposes the first inclined surface 431 and the connection surface 430.

  Thus, by providing the article contact surface 43D with the first inclined surface 431, the second inclined surface 432, and the connection surface 430, the angle of the article contact surface 43D with respect to the floor portion FL is lower and upper. , And change in the middle part. The first inclined surface 431 is a surface that comes in contact with the hose HS resting on the rail 20 first. Therefore, the first sloped surface 431 has a slope which approaches the axle 52 from the lower part to the upper part in order to dive into the lower side of the hose HS and apply a force to lift the hose HS upward. The first inclined surface 431 is inclined such that a force can be exerted to push the hose HS upward even when the speed of the car wash machine body 10D is low. The angle of the first inclined surface 431 with respect to the floor FL is smaller than the angle of the connection surface 430 with respect to the floor FL.

  And connection surface 430 is a floor rather than the 1st slope 431 so that speed of car wash machine main part 10D becomes quick, and hose HS does not move too much when hose HS contacts connection surface 430. The inclination angle with respect to the part FL is tight. The second inclined surface 432 on the upper end side of the article contact surface 43D has an inclination such that the lower side approaches the axle 52. For example, when the speed of the car wash machine body 10D is increased, the force pressing the hose HS in contact with the connection surface 430 is increased, and the article contact surface 43D is moved upward. The hose HS comes into contact with the second inclined surface 432 to apply a force to push the hose HS downward from the second inclined surface 432. Thereby, in the article exclusion unit 40D, the hose HS can be more reliably restrained from moving beyond the upper end of the article contact surface 43D.

  Other features are the same as the features of the first to third embodiments.

<Modification>
In the present embodiment, the article contact surface 43D includes the first inclined surface 431, the second inclined surface 432, and the connection surface 430, but is configured to include the first inclined surface 431 and the second inclined surface 432. It is also good. In addition, as the article contact surface 43D, the first inclined surface 431 may be combined with a surface having a larger inclination angle with the floor portion FL than the first inclined surface 431 (here, a connection surface). Furthermore, in any one of the first inclined surface 431 and the second inclined surface 432, a configuration in which surfaces different in inclination angle are connected may be used. At this time, when changing the inclination of the first inclined surface 431 with respect to the floor portion FL, the upper inclined surface is set to have a larger inclination angle than the lower inclined surface. Moreover, when changing the inclination with respect to the floor part FL of the 2nd inclined surface 432, it sets so that a lower inclined surface may become large in inclination angle rather than an upper inclined surface.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to this content. Moreover, the embodiment of the present invention can add various modifications without departing from the spirit of the invention.

  According to the present invention, the present invention can be used for a car wash machine for washing a vehicle to be washed.
