Formed by a pair of side plates connected outward from both ends in the direction of a mold rail, and on the inner peripheral surface side of the inner plate portion, the engaged portion can be engaged and disengaged from the outside. A ring-shaped portion is formed by connecting the divided bodies in the circumferential direction by fixing the inner end portion of the brush unit between the adjacent side plate portions with the locking tool in a state where the portion is formed in a protruding shape. It is characterized by comprising .

Therefore, according to the first aspect of the present invention , the brush member can be externally fitted to the tubular member with the engaged portion group engaged with the engaging portion group. During the car washing operation, the shaft body is rotated around the shaft center, and the rotational force of the shaft body is transmitted to the cylindrical member of each brush unit, and the rotation of the cylindrical member is engaged with the engaging portion group. It is possible to transmit to each divided body, that is, the ring-shaped portion via the engaged portion group, so that each brush unit can be rotated around the shaft center as a unit with the shaft body. Then, by moving the brush for a car wash machine, the brush member can be brought into contact with (in contact with) the surface of the vehicle to be cleaned and cleaned. At that time, by engaging the engaged portion group with the engaging portion group, it is possible to prevent the positional deviation in the circumferential direction of the rotating brush member with respect to the tubular member, and the rotating brush It is possible to prevent displacement of the member in the longitudinal direction (direction along the axis) with respect to the cylindrical member. As a result, the brush unit group is expanded by the centrifugal force. Therefore, by moving the brush for the car wash machine, the brush unit group that is expanded and rotating is brought into contact (contact) with the surface of the vehicle to be cleaned. Can be washed.
By performing such a cleaning process, when the brush member is consumed or dirty, the target brush member is replaced in a state where the car washing operation is stopped (locked). In other words , the engaged portion can be separated (extracted) from the engaging portion by separating one portion of the ring-shaped portion, that is, between the adjacent divided bodies, by the operation of releasing the locking tool. The worn or dirty brush member can be detached completely from the cylindrical member to the outside. Then , a new brush member is externally fitted to the cylindrical member, and the engaged portion is engaged with the engaging portion, and then the divided bodies are connected in the circumferential direction by the engaging operation of the locking tool to form a ring shape. By configuring the portion, the prepared new brush member can be attached to the cylindrical member from the outside.

By cleaning the front surface of the cleaning vehicle C and simultaneously moving it back together with the rails 18A, the front surface is moved while following the movement of the vehicle C to be cleaned by the conveyor 2, as indicated by the phantom line A in FIG. Can be washed. Next, the pair of left and right second cleaning side brushes 19 positioned on the outside as shown by the solid line in FIG. 3 is moved in the left and right direction (vehicle width direction) as shown by the phantom line in FIG. ), The both side surfaces of the vehicle C to be cleaned are cleaned.

  When the cleaning of both side surfaces by the second cleaning side brush 19 is nearing the end, a pair of left and right first cleaning side brushes 18 that are moved (opened) to the left and right outwards in phantom lines in FIG. Is moved to the left and right inner sides (center side) by the guide of the rail 18A, and the rear surface of the vehicle C to be cleaned is simultaneously moved rearward together with the rail 18A. As shown, the rear surface can be cleaned while being moved following the conveyance of the vehicle C to be cleaned by the conveyor 2. Further, after the fluorine coating agent is sprayed from the water repellent coat arch 20 onto the surface of the vehicle C to be cleaned whose both side surfaces are cleaned by the second cleaning side brush 19, liquid wax is sprayed (sprayed) from the wax arch 21.

  The vehicle to be cleaned C thus cleaned by the cleaning unit 3 is continuously moved by the drying unit 4 while the upper surface is first dried by the air from the first top nozzle 25 and then the air from the first side nozzle 26. The both sides are dried by the above, and the upper surface is dried by the air from the second top nozzle 27, and then both the sides are dried by the air from the second side nozzle 28. Next, the pair of left and right drying side brushes 30 positioned on the outside as shown by the solid line in FIG. 3 are moved in the left and right direction (vehicle width direction) as shown by the phantom line in FIG. By moving inward, water droplets adhering to both side surfaces (surfaces) of the vehicle C to be cleaned are wiped off. Furthermore, the drying top brush 29 that is in the raised position as shown by the solid line in FIG. 2 is moved up and down vertically following the change in the vehicle height as shown by the phantom line in FIG. The water droplets adhering to the upper surface (surface) of the vehicle C are wiped off.

  Here, the water droplet wiping action by the pair of left and right drying side brushes 30 is performed as follows. That is, the shaft body 31 is rotated around the shaft center 31 </ b> A by the rotation drive device 74, and the rotational force of the shaft body 31 is transmitted to the tubular member 41 of each brush unit 40 through the bolt body 35 group. Then, the rotation of the cylindrical member 41 can be transmitted to each divided body 53, that is, the ring-shaped portion 52 through the group of engaged portions 56 engaged with the engaging portion 46. The shaft body 31 and the shaft body 31 can be rotated around the shaft center 31A. At that time, by engaging the engaged portion 56 group with the engaging portion 46 group, the circumferential displacement of the rotating brush member 51 relative to the tubular member 41 can be prevented, and the upper and lower bottom plates Since the engaged portion 56 is located between 45, the positional deviation in the longitudinal direction (direction along the axis 31A) of the rotating brush member 51 with respect to the tubular member 41 can be prevented.

  As a result, the cloth brush unit 68 group is expanded by the centrifugal force, and therefore, the drying side brush 30 is moved inward in the left-right direction (vehicle width direction) by the swing of the arm 71. The rotating cloth brush 68 group can be brought into contact with (in contact with) both side surfaces of the vehicle C to be cleaned, and water droplets adhering to both side surfaces (surfaces) can be wiped off. The water that has entered the cylindrical member 41 during the wiping of such water droplets can be drained to the floor surface F through the drain holes 49 group. The water droplets adhering to the upper surface (surface) of the vehicle C to be cleaned by the drying top brush 29 can be similarly wiped. The vehicle to be cleaned C that has completed the intended car wash as described above can be moved out of the car wash machine main body 1 by the conveyor 2.

  By performing the wiping action of the water droplets by the drying side brush 30 as described above, when the cloth brush 68 is consumed or soiled, the car wash operation is stopped (locked), and the target brush member 51 Exchange. That is, the side (outside) of the abutting plate portion 65 of the second locking tool 64 at a suitable location (arbitrary location) that is easy to operate on the side plate portion 55 via the engagement / disengagement operation portion 66. The portion to be locked 65a is disengaged from the locking portion 63a. As a result, the tightening force applied to the ring-shaped portion 52 in an elastically deformed state can be released, and the elastic repulsive force (elastic release force) can release the locking portion (tip portion) of the pin portion 63 as shown in FIG. ) The portion of the ring-shaped portion 52 can be separated by extracting the 63a side from the through hole 57 of the adjacent side plate portion 55. Further, the ring-shaped portion 52 can be enlarged in diameter by the elastic repulsive force, so that the engaged portion 56 in the vicinity of the separation portion can be automatically detached (extracted) from the engaging portion 46. Therefore, the ring-shaped portion 52 is expanded (further expanded) against its elastic force, so that the brush member 51 in which the cloth brush 68 is worn or soiled is completely removed from the tubular member 41. Can be separated and removed.

  Then, the new brush member 51 that has been prepared can be mounted on the tubular member 41 by performing an operation reverse to the above-described operation of separating and removing. That is, as shown in FIG. 8, a new brush member 51 is fitted on the tubular member 41, the engaged portion 56 is engaged with the engaging portion 46, and then the ring-shaped portion 52 is elastically deformed into a tightening shape. In this state, the pin portion 63 of the first locking member 61 inserted from the through hole 57 in the side plate portion 55 of one divided body 53 to the hole portion 69 of the cloth brush unit 68 is connected to the other divided body 53. The side plate portion 55 is inserted through the through hole 57. And after making the contact plate part 65 of the 2nd latching tool 64 contact | abut to the side plate part 55 of the other division body 53, it faces the inner plate part 54 on the side plate part 55 via the engagement / disengagement operation part 66. By sliding and engaging the locked portion 65a with the locking portion 63a from the outside, the brush unit 40 with the new brush member 51 mounted on the tubular member 41 can be formed as shown in FIG.

  Thus, the replacement work of the brush member 51 can be performed in a short time without using a tool or the like, and can be easily and quickly performed by a staff at a gas station. Therefore, the stop time of the car wash machine can be shortened, the car wash waiting time can be shortened and a suitable car wash can be performed, and the water droplet wiping action can be performed in a clean state at all times.

  As described above, the brush member 51 completely separated and removed from the tubular member 41 can be prepared for the next replacement by washing and drying the cloth brush 68 group and the like. The brush member 51 can be suitably used as a drying brush member 51 that is easily soiled and that needs to be replaced periodically.

  The worn brush member 51 is attached by attaching a new cloth brush 68 to the pin 63 after removing the worn cloth brush 68 from the pin 63 from which the second locking member 64 has been detached. All of the cloth brush single bodies 68 or a specific cloth brush single body 68 that is heavily consumed such as breakage can be replaced. At that time, the replacement work was performed in a state in which the brush member 51 was separated from the tubular member 41 and removed (washable state), or as shown in FIG. It can be performed in a state (a state in which the diameter has been expanded).
