Description

  The present invention relates to a car wash machine and a car wash method provided with a side brush for washing a side surface of a vehicle.

  2. Description of the Related Art Conventionally, as a car wash machine, there is a car wash machine in which a gate-shaped car wash machine body moves back and forth with respect to a vehicle to be washed stopped on the ground. A pair of left and right side brushes are provided in the car wash machine body.

  According to this, as shown in FIG. 22, the both side brushes 86 are moved forward (S-1) while the both side brushes 86 are closed to the closing limit position S and rotated at a predetermined rotational speed (S-1). When 86 reaches the front surface of the vehicle 88 to be cleaned, the car wash machine main body 87 is temporarily stopped, and both side brushes 86 are opened to the open position O in the left-right direction (S-2), and the front surface of the vehicle 88 to be cleaned is opened. Wash with both side brushes 86. Thereafter, both side brushes 86 are slightly closed from the open limit position O, and the car wash machine main body 87 is moved forward to clean both side surfaces of the vehicle 88 to be cleaned with both side brushes 86 (S-3). Thereafter, when both side brushes 86 reach the rear end of the vehicle 88 to be cleaned, the car wash machine main body 87 is temporarily stopped and both the side brushes 86 are closed to the closing position S so that the rear surface of the vehicle 88 to be cleaned is Wash with the side brush 86 (S-4).

However, the above conventional format has the following problems.
1) As shown in FIG. 23, when the side surface of a sedan type vehicle to be cleaned 88 provided with a fender mirror 90 at the front end of the vehicle body is cleaned, there is a risk that the outer peripheral tip of the side brush 86 may be entangled with the fender mirror 90. For this reason, the rotation of the side brush 86 is stopped only within a certain range W (shaded portion) of the fender mirror 90. Therefore, there is a problem that unwashed parts are generated on both side surfaces of the vehicle body by the predetermined range W.

  2) As shown in FIG. 24, when cleaning the front surface of a wagon type vehicle to be cleaned 88 having a front mirror 91 at the front end of the vehicle body, the outer peripheral tip of the side brush 86 may be entangled with the front mirror 91. Therefore, after the closed both side brushes 86 abut on the front surface of the vehicle 88 to be cleaned (S-1), the car wash machine main body 87 is slightly moved backward once so that the both side brushes 86 are moved to the front surface of the vehicle 88 to be cleaned. (S-2), both side brushes 86 are opened from the closed limit position S to the open limit position O (S-3), and the car wash machine body 87 is moved forward to move both sides of the vehicle 88 to be cleaned. The surface was shifted to cleaning (S-4). As a result, the side brush 86 can avoid the front mirror 91, but there is a problem that unwashed parts are generated on the front surface of the vehicle body only in a certain left and right range W (shaded portion) of the front mirror 91.

  Also, when washing the rear surface of a wagon type vehicle 88 having a rear mirror (not shown) provided at the rear end of the vehicle body, the rear surface of the rear mirror 92 is washed to the rear surface of the vehicle body only within a certain left and right range as described above. There is a problem that a leftover occurs.

  The present invention can reduce the unwashed portion of the vehicle to be cleaned when the vehicle to be cleaned is cleaned with the side brush even when the vehicle to be cleaned is provided with projections that interfere with the car wash. An object is to provide a car wash and a car wash method.

In order to achieve the above object, the first aspect of the present invention is a car wash method using a car wash machine in which at least one of a car wash machine body and a vehicle to be washed moves to perform car wash,
The car wash machine body, the same as the vertical direction axis is divided into rotatable upper and lower plurality of brush body around the the pair of right and left side brush, and a plurality of rotary drive device for the respective brush body driven individually rotate A switch that is turned on when the vehicle to be cleaned is provided with a projection that interferes with the car wash ,
By first turning on the switch according to the protrusion provided on the vehicle to be cleaned, the brush body at a position corresponding to the height of the protrusion is moved to a predetermined position by the rotation driving device of the brush body. The car is washed by rotating or stopping the rotation at a lower speed than the rotation speed, and rotating the remaining brush bodies at the predetermined rotation speed by the rotation driving device of each brush body.

According to this, by turning on the switch first and changing the rotational drive speed of each rotational drive device, the rotational speed of each brush body is changed to a predetermined rotational speed, a rotational speed lower than the predetermined rotational speed, and a rotational speed. Ru can be switched to a stop.
When cleaning the vehicle to be cleaned by rotating the side brush, if the vehicle to be cleaned has a projection that interferes with the vehicle wash, the height of the projection is set by turning on the switch first. Since the brush body at a position corresponding to is rotated at a lower speed than the predetermined rotation speed or stopped rotating, and the remaining brush body rotates at the predetermined rotation speed, the outer peripheral tip of the side brush is prevented from being entangled with the projection. Further, it is possible to reduce the unwashed portion of the vehicle to be cleaned.

  As described above, according to the present invention, when a vehicle to be cleaned provided with a protrusion that interferes with car washing is cleaned with a side brush, the outer peripheral tip of the side brush can be prevented from being entangled with the protrusion, Thus, it is possible to reduce the unwashed portion of the vehicle to be cleaned.

These switches 55 to 58 switch the driving of the upper motor 41 and the lower motor 42.

Hereinafter, the operation of the above configuration will be described.
(A) First, the case where a normal car wash is performed on the vehicle 63 to be cleaned will be described with reference to FIG.

  [1] First, when the car wash is started, the expansion and contraction of the piston rods of both cylinder devices 14 is switched to a free state, whereby the weights of both weights 20 cause the wires 19a and 19b to be pulled. The moving bodies 10a and 10b move from the open limit position O to the close limit position S, and as a result, both side brushes 2 are closed from the open limit position O to the close limit position S as shown in FIG. 1).

  At this time, the upper motor 41 is driven, the rotation transmission shaft 36 is rotated through the upper sprockets 44 and 45 and the upper chain 46, and the upper outer cylinder 26 is moved through the lower sprockets 37 and 38 and the lower chain 39. Rotate. As a result, the upper brush body 23 rotates about the vertical axis 25. Further, the lower motor 42 is driven, the rotary shaft 30 rotates through the upper sprockets 47 and 48 and the upper chain 49, and the lower outer cylinder 28 rotates. As a result, the lower brush body 24 also rotates around the vertical axis 25 in the same manner as the upper brush body 23. At this time, the upper brush body 23 and the lower brush body 24 rotate at a predetermined rotation speed (high-speed rotation).

  In this state, the car wash machine main body 1 is moved forward, both side brushes 2 come into contact with the front surface of the vehicle 63 to be cleaned (S-2), and both side brushes 2 are inclined rearward. As a result, as shown in FIG. 4, since the guide rail 5 swings backward by a predetermined angle α and the limit switch 51 is switched from OFF to ON, both side brushes 2 are brought into contact with the front surface of the vehicle 63 to be cleaned. The contact is detected, and the car wash machine main body 1 is temporarily stopped.

  [2] Then, as shown by the phantom lines in FIG. 2, the piston rods of both cylinder devices 14 extend and the arm 12 swings, and both the moving bodies 10a, 10b moves from the closed limit position S to the open limit position O (S-3), so that both side brushes 2 are opened from the closed limit position S to the open limit position O, and the front surface of the car wash machine body 1 is moved. Wash.

  [3] After that, the car wash machine main body 1 travels forward again, and the expansion and contraction of the piston rods of both cylinder devices 14 is switched to a free state. Then, it moves in the closing direction from the open limit position O, contacts the left and right side surfaces of the vehicle 63 to be cleaned, and the left and right side surfaces of the vehicle 63 to be cleaned are cleaned from the front end to the rear end by the forward traveling of the car wash machine body 1 ( S-4).

  [4] When both side brushes 2 reach the rear end of the vehicle 63 to be cleaned (this is detected by the vehicle height detection device 3 detecting the rear end of the vehicle 63 to be cleaned). 2 wash | cleans the rear surface of the car-washing machine main body 1, closing to the closed limit position S by the weight urging | biasing of both weights 20 (S-5).

  Through the procedures [1] to [4] as described above, the front surface, both side surfaces, and the rear surface of the vehicle 63 to be cleaned are cleaned using the both side brushes 2, and at the same time, the upper surface of the vehicle 63 to be cleaned and the lower portions of both sides , Tires etc. are cleaned with top brush or rocker brush.

  (B) As shown in FIGS. 9 and 10, when a wagon-type vehicle to be cleaned 63 provided with a front mirror 65 (an example of a protrusion that obstructs a car wash) at the front end of the vehicle body is first cleaned. The attendant turns on the front mirror switch 56 (see FIG. 1). Thus, after the cleaning process [1], when the front side of the car washer 1 is cleaned while both side brushes 2 are opened from the closed limit position S to the open limit position O in the cleaning process [2] above, The motor 41 stops, the rotation of the upper brush body 23 of both side brushes 2 stops, and only the lower brush body 24 rotates at a predetermined rotation speed (high-speed rotation).

  Therefore, since the rotation of the upper brush body 23 is stopped as described above, it is possible to prevent the bristles 27 of the upper brush body 23 from being entangled with the front mirror 65. At this time, since the lower brush body 24 is rotating at a predetermined rotational speed, the substantially lower half of the front surface of the vehicle 63 to be cleaned is cleaned by the lower brush body 24. Therefore, compared with the conventional car wash, the unwashed part in the front surface of the to-be-washed vehicle 63 can be reduced. Thereafter, the cleaning steps [3] and [4] are performed.

  In the case of the above (B), the rotation of the left and right upper brush bodies 23 is stopped, but only the upper brush body 23 on the side where the front mirror 65 is provided (generally the left side) is stopped and the opposite side ( The upper brush body 23 on the right side may be rotated at a predetermined rotational speed (high speed rotation) in the same manner as the lower brush body 24. Thereby, the unwashed part in the front surface of the vehicle 63 to be cleaned can be further reduced. Alternatively, the upper brush body 23 on the side where the front mirror 65 is provided (generally, the left side) may be rotated at a low-speed rotation lower than a predetermined rotation speed.

  (C) Also, as shown in FIG. 11, when a sedan type vehicle to be cleaned 63 provided with a fender mirror 67 (an example of a projection that obstructs car wash) is provided at the front end of the vehicle body, The attendant turns on the fender mirror switch 55 (see FIG. 1). Thus, after the cleaning strokes [1] and [2], in the cleaning stroke [3], within the range B that is a predetermined distance including the fender mirror 67 from the front ends of the left and right side surfaces of the vehicle 63 to be cleaned. Thus, the upper motor 41 stops, the rotation of the upper brush bodies 23 of both side brushes 2 stops, and only the lower brush body 24 rotates at a predetermined rotation speed (high-speed rotation).

  Therefore, since the rotation of the upper brush body 23 is stopped as described above, the bristles 27 of the upper brush body 23 can be prevented from being entangled with the fender mirror 67. At this time, since the lower brush body 24 rotates at a predetermined rotation speed, the range B behind the predetermined distance from the front end of the vehicle 63 to be cleaned is cleaned only by the lower brush body 24. Therefore, compared with the conventional car wash, the unwashed portions on both side surfaces of the vehicle 63 to be cleaned can be reduced.

  When both side brushes 2 reach the rear end of the range B, the upper motor 41 is driven to rotate, and the upper brush body 23 rotates at a predetermined rotation speed (high-speed rotation). Thereby, after both the side brushes 2 reach the rear end of the range B, both side surfaces of the vehicle 63 to be cleaned are cleaned by the upper brush body 23 and the lower brush body 24. Thereafter, the cleaning step [4] is performed.

  (D) Also, as shown in FIG. 12, when a vehicle to be cleaned 63 provided with a carrier 69 (an example of a protrusion that obstructs a car wash) is provided on the ceiling of the vehicle body, first, an attendant must The sun visor switch 58 (see FIG. 1) is turned on. As a result, after the cleaning strokes [1] and [2], the rotational drive speed of the upper motor 41 is switched to a low speed in the cleaning stroke [3], and the upper brush bodies 23 of both side brushes 2 are predetermined. The lower brush body 24 rotates at a predetermined rotation speed (high-speed rotation) in the same manner as the cleaning step [3] above.

  As a result, the upper half of the both side surfaces of the vehicle 63 to be cleaned is cleaned by the upper brush body 23 that rotates at a low speed, thereby preventing the bristles 27 of the upper brush body 23 from being entangled with the side end of the carrier 69. can do. At this time, since the lower brush body 24 rotates at a predetermined rotational speed (high-speed rotation), the lower brush body 24 sufficiently cleans the range of the substantially lower half of both side surfaces of the vehicle 63 to be cleaned. Thereafter, the cleaning step [4] is performed.

  (E) Further, as shown in FIG. 12, the above-mentioned (D) is also performed when the vehicle to be cleaned 63 provided with a sun visor 71 (an example of a protrusion that obstructs the car wash) is provided on the window frame portion of the vehicle body. As in the case of), first, the attendant turns on the carrier sun visor switch 58. As a result, the same car washing as in the case of (D) is performed, and the upper brush body 23 rotating at a low speed rotates the upper half range of both side surfaces of the vehicle 63 to be cleaned. It is possible to prevent the hair 27 from being entangled with the sun visor 71. At this time, since the lower brush body 24 rotates at a predetermined rotational speed (high-speed rotation), the lower brush body 24 sufficiently cleans the range of the substantially lower half of both side surfaces of the vehicle 63 to be cleaned.

  (F) Also, as shown in FIG. 13, when cleaning a wagon-type cleaned vehicle 63 provided with a rear mirror 73 (an example of a projection that obstructs a car wash) at the rear end of the vehicle body, The attendant turns on the rear mirror switch 57 (see FIG. 1). As a result, after the cleaning steps [1] to [3], both side brushes 2 after cleaning both side surfaces of the vehicle 63 to be cleaned are closed to the closed position S in the cleaning step [4]. When the rear surface of the cleaning vehicle 63 is cleaned, the rotational drive speed of the upper motor 41 is switched to a low speed, and the upper brush bodies 23 of both side brushes 2 rotate at a low speed rotation lower than a predetermined rotation speed (high speed rotation). At the same time, the lower brush body 24 rotates at a predetermined rotation speed (high-speed rotation) in the same manner as in the cleaning step [4].

  As a result, the upper half of the rear surface of the vehicle 63 to be cleaned is cleaned by the upper brush body 23 that rotates at a low speed, so that the brush bristles 27 of the upper brush body 23 can be prevented from being entangled with the rear mirror 73. At this time, since the lower brush body 24 rotates at a predetermined rotational speed (high-speed rotation), the lower brush body 24 sufficiently cleans the range of the substantially lower half of the rear surface of the vehicle 63 to be cleaned.

  As shown in FIG. 13, not only the rear mirror 73 but also a rear wiper 74 (an example of a protrusion that obstructs the car wash) is provided in the same manner as the above (F). The rear surface can be cleaned.

Hereinafter, a second embodiment of the present invention will be described with reference to FIGS.
As shown in (F) above, when cleaning a wagon-type vehicle 63 having a rear mirror 73 provided at the rear end of the vehicle body, first, an attendant turns on a rear mirror switch 57 (see FIG. 1). Leave it on. As a result, the two side brushes 2 that have cleaned the rear ends of both side surfaces of the vehicle 63 to be cleaned in the cleaning process [3] after the cleaning processes [1] and [2] are as shown in FIG. In the open state, the car wash machine main body 1 moves forward to move rearward a predetermined distance away from the rear surface of the vehicle 63 to be cleaned. At this time, the upper brush body 23 and the lower brush body 24 are both rotated at a predetermined rotation speed (high-speed rotation).

  [4-a]: The both side brushes 2 that have been opened close to the closing limit position S, and the car wash machine body 1 is switched from forward travel to reverse travel. Then, as shown in FIG. 15, both side brushes 2 in the closed limit position S abut on the rear surface of the vehicle 63 to be cleaned, and both side brushes 2 are inclined forward as indicated by phantom lines in FIG. 6. Since the guide rail 5 swings forward by a predetermined angle α and the limit switch 51 is switched from OFF to ON, it is detected that both side brushes 2 are in contact with the rear surface of the vehicle 63 to be cleaned. 1 pauses. At this time, the upper brush body 23 is switched from a predetermined rotation speed (high speed rotation) to a low speed rotation, and the rotation of the lower brush body 24 is stopped. In this state, the upper brush body 23 is in close contact with the inclined surface of the upper half of the rear surface of the vehicle 63 to be cleaned.

  [4-b]: Both side brushes 2 are maintained for a certain time in the state of the inclined posture shown in FIG. 15, and thereafter open from the closed position S to the open position O as shown in FIG. Accordingly, only the upper half of the rear surface of the vehicle 63 to be cleaned is reliably cleaned by the upper brush body 23 that rotates at a low speed. At this time, the rotation of the lower brush body 24 is stopped when the lower brush body 24 is rotated while the side brush 2 is inclined as described above, and an excessive load is applied to the side brush 2. Because.

  [4-c]: After that, the car wash machine body 1 is slightly moved forward so that both side brushes 2 inclined forward as shown in FIG. 15 return to the vertical posture as shown in FIG. The stopped lower brush body 24 rotates at a predetermined rotational speed (high-speed rotation), and both side brushes 2 close from the open limit position O to the close limit position S. As a result, the lower brush body 24 cleans substantially the lower half of the rear surface of the vehicle 63 to be cleaned while being in close contact with the vertical surface of the lower half of the rear surface of the vehicle 63 to be cleaned, and rotates at a low speed. The upper brush body 23 cleans the upper half of the rear surface of the vehicle 63 to be cleaned. At this time, the rotation direction of the upper brush body 23 and the lower brush body 24 is switched to the opposite direction to the rotation direction of the upper brush body 23 in the cleaning process [4-b].

  In this way, in the cleaning process [4-b], as shown in FIG. 15, the upper brush body 23 cleans almost the upper half of the rear surface of the vehicle 63 to be cleaned at a low speed rotation. It is possible to prevent the bristles 27 from being entangled with the rear mirror 73. Further, when the upper half of the rear surface of the vehicle 63 to be cleaned is cleaned, the upper brush body 23 is inclined along the inclined surface of the upper half of the rear surface, so that more reliable cleaning can be performed. Further, in the cleaning process [4-c], as shown in FIG. 17, when the lower half of the rear surface of the vehicle 63 to be cleaned is cleaned, the lower brush body 24 is placed on the vertical surface of the lower half of the rear surface. Since it becomes a vertical posture along, more reliable cleaning can be performed.

Hereinafter, a third embodiment of the present invention will be described with reference to FIGS.
In the first embodiment, the rear mirror switch 57 is provided on the front surface of the car wash machine body 1, but in the third embodiment, the rear mirror switch 57 is replaced with a left rear mirror switch 57a and a right rear mirror switch 57b. It is divided.

  According to this, as shown in FIG. 19, when cleaning a wagon type vehicle to be cleaned 63 provided with a rear mirror 73 (an example of a protrusion that obstructs a car wash) on the left side of the rear end of the vehicle body, The attendant turns on the left rear mirror switch 57a. As a result, after the cleaning steps [1] to [3], both side brushes 2 after cleaning both side surfaces of the vehicle 63 to be cleaned are closed to the closed position S in the cleaning step [4]. When cleaning the rear surface of the cleaning vehicle 63, only the left upper motor 41 is stopped, only the rotation of the upper brush body 23 of the left side brush 2 is stopped, and the lower brush body 24 and the right side of the left side brush 2 are stopped. The upper and lower brush bodies 23 and 24 of the side brush 2 rotate at a predetermined rotation speed (high-speed rotation).

  Thereby, it is possible to prevent the bristles 27 of the upper brush body 23 (stop) of the left side brush 2 from being entangled with the rear mirror 73. At this time, the range of the substantially lower half of the rear surface of the vehicle 63 to be cleaned is cleaned by the left and right lower brush bodies 24, and the range of the upper half and the right half of the rear surface of the vehicle 63 to be cleaned is the right side brush 2. The upper brush body 23 is cleaned. Thereby, it is possible to reduce the unwashed portion of the rear surface of the vehicle 63 to be cleaned.

  In addition, as shown in FIG. 20, when a wagon type vehicle to be cleaned 63 provided with a rear mirror 73 (an example of a protrusion that obstructs a car wash) is provided on the right side of the rear end of the vehicle body, Turns on the right rear mirror switch 57b. As a result, after the cleaning steps [1] to [3], both side brushes 2 after cleaning both side surfaces of the vehicle 63 to be cleaned are closed to the closed position S in the cleaning step [4]. When cleaning the rear surface of the cleaning vehicle 63, only the upper motor 41 on the right side stops, only the rotation of the upper brush body 23 of the right side brush 2 stops, and the lower brush body 24 and the left side of the right side brush 2 stop. The upper and lower brush bodies 23 and 24 of the side brush 2 rotate at a predetermined rotation speed (high-speed rotation).

  Thereby, it is possible to prevent the bristles 27 of the upper brush body 23 (stop) of the right side brush 2 from being entangled with the rear mirror 73. At this time, the range of the lower half of the rear surface of the vehicle 63 to be cleaned is cleaned by the left and right lower brush bodies 24, and the range of the upper half and the left half of the rear surface of the vehicle 63 to be cleaned is the left side brush 2. The upper brush body 23 is cleaned. Thereby, it is possible to reduce the unwashed portion of the rear surface of the vehicle 63 to be cleaned.
