Description

  The present invention relates to a car wash machine that cleans a car to be cleaned by a cleaning means while relatively moving the vehicle to be cleaned and a car wash machine body in the front-rear direction.

  Conventionally, the following configuration is provided as this type of car wash machine. That is, the side brush provided in the car wash machine main body is divided into upper and lower two-stage (upper and lower) brush bodies. When the vehicle to be cleaned is provided with a projection that obstructs the car wash when the side brush is driven to rotate, the brush body at a position corresponding to the height of the projection is provided. The rotation is stopped at a lower speed than the predetermined rotation speed or the rotation is stopped, and the remaining brush body rotates at the predetermined rotation speed. Thereby, it can prevent that the outer periphery front-end | tip of a side brush gets entangled with a protrusion, and also can reduce the unwashed part of a to-be-cleaned vehicle. Further, the car wash machine main body is provided with a plurality of rotation drive devices that individually rotate and drive the brush bodies (see, for example, Patent Document 1).

  However, according to the configuration of Patent Document 1 described above, a configuration is provided in which an upper motor (rotational drive device) that rotationally drives the upper brush body and a lower motor (rotational drive device) that rotationally drives the lower brush body, That is, since the number of rotation driving devices equal to the number of brush bodies is provided, for example, when the side brush is constituted by a brush body that is divided into three parts, three rotation driving devices are required, The drive structure is complicated and large.

  For this, an intermediate brush is provided between an upper brush and a lower brush that are rotationally driven by a drive shaft, and this intermediate brush is rotatable integrally with the upper brush via an annular friction plate or the like. Configurations are provided. According to this configuration, when the intermediate brush reaches a projection such as a door mirror and the rotational resistance reaches a limit determined by the annular friction plate, only the intermediate brush slips and rotates at a reduced speed or stops, and the projection. After passing, the structure which becomes constant speed with both upper and lower brushes and continues a car wash is provided (for example, refer patent document 2).

An upper brush, an intermediate brush, and a lower brush are attached to a drive shaft that is rotationally driven by the drive means, and the upper brush and the lower brush are fixed to the drive shaft, respectively, and the intermediate brush is interposed via a magnetic means. A configuration is provided that is coupled to the upper brush. According to this configuration, when the rotating brush device reaches the position of the fender mirror or the door mirror, the intermediate brush strikes the mirror, and a resistance force acts on the intermediate brush in the direction opposite to the rotational operation direction, and the resistance force is a magnetic means. When the coupling force is exceeded, the intermediate brush rotates relative to the drive shaft and rotates at a slower speed than the upper and lower brushes, or stops rotating (for example, see Patent Document 3).

  Accordingly, the invention according to claim 1 of the present invention is a type in which the brush body of the brush device is divided into three parts, and each brush body is driven and rotated separately by two rotation driving means and a connection / disconnection operation (clutch operation) ( The object of the present invention is to provide a car washing machine that can be rotated (washing rotation) and stopped (washing stopped), and that the entire drive structure can be simplified, reduced in size, and reduced in weight.

  In order to achieve the above-described object, a car wash machine according to claim 1 of the present invention is a car wash machine that performs washing of a vehicle to be cleaned by a cleaning means while relatively moving the vehicle to be cleaned and the car wash machine body in the front-rear direction. The brush body of the brush device is divided into three in the direction of the rotation axis of the inner cylinder member rotatably provided on the main body side member, and one first end brush body is rotatable on the inner cylinder member. The first end outer cylindrical member is supported, and a first end brush member group attached to the outer peripheral surface of the first end outer cylindrical member. The intermediate brush body is rotatable on the inner cylindrical member.

  As described above, when the target brush body is not driven, the first end brush body and the second end brush body are stopped from rotating at the same time as the non-driven state, and the intermediate brush material is water-containing. Because it is heavy in the state, the inertial rotation is small and the rotation is immediately stopped. Then, after the non-driven brush body passes through the protrusion, the basic first cleaning pattern in which the three brush bodies are driven and rotated again by the two rotational driving means can be returned. As a result, the vehicle to be cleaned can be cleaned by the brush device.

  The car wash machine according to claim 2 of the present invention is the above-described configuration according to claim 1, wherein the brush device is a side brush device, and the brush body includes an upper first end brush body, an intermediate brush body, The lower end second brush body is divided into three in the vertical direction and is externally fitted to the inner cylinder member in the vertical direction.

Thus, a fifth cleaning pattern in which only the second end brush body is driven can be obtained.

  As described above, when the target brush body is not driven, the first end brush body and the second end brush body can be stopped from rotating simultaneously with the non-drive state, and the intermediate brush material is water-containing. Because it is heavy in the state, the inertial rotation is small and the rotation can be stopped immediately. Then, after the non-driven brush body passes through the projection, it can be returned to the basic first cleaning pattern in which the three brush bodies are driven and rotated again by the two rotational driving means. Thereby, the washing | cleaning operation | work of the to-be-cleaned vehicle by a brush apparatus can be performed.

A third cleaning pattern in which the end brush body is not driven can be obtained. At this time, in the intermediate brush body and the second end brush body, the remaining portion can be reduced by continuing the cleaning of the lower portion with respect to the protrusion portion.

  According to the third aspect of the present invention described above, the expansion / contraction member is inflated by supplying fluid and is brought into pressure contact with the inner surface of the intermediate outer cylinder member, whereby the inner cylinder member can be connected to the intermediate outer cylinder member, and expansion / contraction By stopping the supply of fluid to the member and releasing the fluid in the expansion / contraction member, the expansion / contraction member can be contracted to separate the inner cylinder member and the intermediate outer cylinder member, and the intermediate outer cylinder member Can be driven.

The fluid pressure expands against its own elasticity and is pressed against (connected to) the inner surface 58a of the intermediate outer cylinder member 58, whereby the rotational force of the inner cylinder member 46 is intermediated via the expansion / contraction member 70. The intermediate brush member 59 is integrally rotated by being transmitted to the outer cylinder member 58.

  Between the guide rail 21 and the holders 22A and 22B, as shown in FIG. 5, support guide protection devices 90A and 90B for power supply lines, signal wirings, and the like are provided. The supply / discharge hose 75 is disposed through the inside of 90A and 90B, and the proximal end of the supply / discharge hose 75 is connected to a pressurized air supply source such as a blower device 14 or a separate blower device. Further, a three-way valve (not shown) is provided in the supply / discharge hose 75 or the like, and by switching, a pressurized air P is supplied to the expansion / contraction member 70 or the inside of the expansion / contraction member 70 is opened to the atmosphere. It is configured as follows.

  Here, the heights of the side brush bodies 50A, 50B by three divisions, that is, the heights (cleaning zones) of the first end brush body 51, the intermediate brush body 56, and the second end brush body 61 are shown in FIG. As shown in FIG. 9, the intermediate brush body 56 is opposed to the side mirror (an example of the protrusion) AM of the ordinary passenger car A and the side mirror (an example of the protrusion) BM of the light car (an example of the vehicle to be cleaned) B. As shown in FIG. 10, the first end brush body 51 is set to face a side mirror (an example of a protrusion) CM of a one-box car (an example of a vehicle to be cleaned) C. Then, based on detection of a point location (for example, a window near the side mirror AM, BM, CM, the side mirror AM, BM, CM itself, a car shape, etc.) of the passenger car A, the light car B, or the one box car C. In addition, driving or stopping of both rotation driving means 80 and 85, switching of the three-way valve, and the like are configured to be controlled by the control unit.

Below, the washing | cleaning operation | work of the normal passenger car A by the structure of the side brush apparatus 20 in Embodiment 1 is demonstrated.
As shown by the phantom line in FIG. 8, the first rotation driving means 80 is supplied in a state where the inner cylinder member 46 is connected to the intermediate outer cylinder member 58 by supplying the pressurized air P and expanding the expansion / contraction member 70. By rotating the rotation motor 81, the first end brush body 51 is rotated to rotate the first end brush material 54, and the rotation motor 86 of the second rotation driving means 85 is rotated. The second end brush body 61 is rotated to rotate the second end brush material 64, and the intermediate brush body 56 is rotated via the expansion / contraction member 70 to rotate the intermediate brush material 59. That is, the three brush bodies 51, 56, 61 can be driven and rotated by the two rotation driving means 80, 85 (first cleaning pattern).

  By this basic cleaning (first cleaning pattern), the first end brush material 54 of the first end brush body 51 comes into contact with the upper surface of the front and rear surfaces and side surfaces of the ordinary passenger car A, and The intermediate brush member 59 of the intermediate brush body 56 is in contact with the front and rear surfaces and the side surface of the intermediate portion of the passenger car A to clean the surface of the intermediate portion, and the second end brush body. The second end brush material 64 of 61 contacts the lower surface of the front and rear surfaces and side surfaces of the ordinary passenger car A, and cleans the lower surface.

  During such basic cleaning, when the intermediate brush material 59 of the intermediate brush body 56 approaches the side mirror AM, the three-way valve is switched under the control of the control unit, and the pressurized air to the expansion / contraction member 70 is changed. While the supply of P is stopped, the inside of the expansion / contraction member 70 is opened to the atmosphere, whereby the expansion / contraction member 70 is contracted as shown by the solid line in FIG. As a result, the intermediate outer cylinder member 58 is brought into a non-driven state. That is, the two brush bodies 51 and 61 can be driven and rotated by the two rotation driving means 80 and 85, and the intermediate brush body 56 can be non-driven (second cleaning pattern).

  At this time, since the intermediate brush member 59 is heavy in a water-containing state, the intermediate brush member 56 is immediately stopped due to a little inertial rotation as shown in FIG. 4, and the intermediate brush member 59 is entangled with the side mirror AM. In other words, the possibility that the side mirror AM is damaged by the rotation of the intermediate brush body 56 can be avoided. Further, at this time, the first end brush body 51 and the second end brush body 61 can reduce the amount of unwashed portions by continuing the cleaning of the upper and lower portions with respect to the portion of the side mirror AM. Then, after the intermediate brush body 56 has passed through the side mirror AM, the expansion / contraction member 70 is expanded again by the pressurized air P, and the inner cylinder member 46 is connected to the intermediate outer cylinder member 58, so that two rotation drives are performed. The basic cleaning (first cleaning pattern) in which the three brush bodies 51, 56, 61 are driven and rotated by the means 80, 85 can be returned. As a result, the ordinary passenger car A can be cleaned by the side brush device 20.

  Further, the cleaning operation of the light vehicle B by the side brush device 20 can be performed in the same manner as the cleaning operation of the ordinary passenger car A. That is, during the basic cleaning (first cleaning pattern) in which the three brush bodies 51, 56, 61 are driven and rotated by the two rotation driving means 80, 85, the intermediate brush material 59 of the intermediate brush body 56 is moved to the side mirror BM. 9, as shown in FIG. 9, the two brush bodies 51 and 61 can be driven and rotated by the two rotation driving means 80 and 85, and the intermediate brush body 56 can be non-driven (second cleaning pattern). Then, after the intermediate brush body 56 passes through the portion of the side mirror BM, it can be returned to basic cleaning (first cleaning pattern) again.

  In order to perform the cleaning operation of the one-box car C by the side brush device 20, first, basic cleaning (first cleaning pattern) in which the three brush bodies 51, 56, and 61 are driven and rotated by the two rotational driving means 80 and 85. I do. During such basic cleaning, when the first end brush material 54 of the first end brush body 51 approaches the side mirror CM, the drive of the first rotation driving means 80 is stopped by the control of the control unit, Thus, the first end outer cylinder member 53 is not driven. That is, the second end brush body 61 and the intermediate brush body 56 can be driven and rotated by the second rotation driving means 85, and the first end brush body 51 can be non-driven (third cleaning pattern).

  At this time, as shown in FIG. 10, the first end brush body 51 is in a rotation stop state simultaneously with the non-drive state, so that the first end brush material 54 is entangled with the side mirror CM or the side mirror CM is The risk of damage due to the rotation of the one-end brush body 51 can be avoided. At this time, since the intermediate brush body 56 and the second end brush body 61 are continuously cleaned with respect to the portion of the side mirror CM, it is possible to reduce unwashed portions. And after the 1st end brush body 51 passes the part of the side mirror CM, the 1st rotational drive means 80 is driven again, The three brush bodies 51,56,61 are driven by the two rotational drive means 80,85. It is possible to return to the basic cleaning (first cleaning pattern) where the drive rotates.

  In addition to the first to third cleaning patterns described above, the following cleaning patterns are also possible. That is, the fourth cleaning pattern in which the first end brush body 51 is driven by the first rotation driving means 80 and the second end brush body 61 and the intermediate brush body 56 are not driven by the drive stop of the second rotation driving means 85. Further, the first end brush body 51 is not driven by stopping the driving of the first rotation driving means 80, the second end brush body 61 is driven to rotate by the second rotation driving means 85, and the intermediate brush body 56 is not driven. A fifth cleaning pattern can also be formed.

  As described above, the first end brush body 51 and the second end brush body 61 can be driven to rotate independently of each other, and the intermediate brush body 56 can be driven to rotate by being connected to the second end brush body 61. Only the brush body 56 can be stopped from rotation, either the first end brush body 51 or the second end brush body 61 can be stopped from rotating, or can be driven to rotate in opposite directions. Further, when projections such as the side mirrors AM, BM, CM are provided on the side surface, if one or both of the first end brush body 51 and the intermediate brush body 56 are stopped at the position of the projections, It is possible to avoid the possibility that the brush members 54 and 59 get entangled with the protrusions, or the protrusions may be damaged by the rotation of the first end brush body 51 or the intermediate brush body 56. At this time, the remaining brush bodies continue to be cleaned. By doing so, it is possible to reduce unwashed areas around the side mirrors AM, BM, CM (particularly below the mirrors).

  As described above, the side brush bodies 50A and 50B of the side brush device 20 are divided into the three brush bodies 51, 56, and 61, but the two rotational driving means 80 and 85 and the pressurized air P are used. Each brush body 51, 56, 61 can be driven and rotated (cleaning rotation) or stopped (washing stopped) individually by connecting / disconnecting operation (clutch operation) by the expansion / contraction member 70, and power saving can also be expected. . In addition, the fluid drive connection / disconnection operation (clutch operation) type comprising the inner cylinder member 46 and the expansion / contraction member 70 can simplify the overall drive structure, and can be made compact and lightweight.

  By driving the traveling motor 28, the holders 22A and 22B travel in the left-right direction. At this time, when the holders 22A and 22B move to the open limit position O, the open limit sensor 43 operates to stop traveling in the open direction, and when the holders 22A and 22B move to the close limit position S, the close limit sensor 41 operates to close the closing direction. Travel to is stopped. The position sensor 40 including a pair of left and right photoelectric switches detects the unevenness of the position detection body 25a and measures the travel positions of the holders 22A and 22B. Thus, the position control of the side brush bodies 50A and 50B in the left and right direction is controlled. It becomes possible, and the position of each side brush body 50A, 50B can be controlled in accordance with the arrangement and shape of the vehicle to be cleaned.

  Further, while the holder main body 27 of the left traveling holder 22A is traveling in the left direction in the closing direction, the side brush main body 50A is pressed in contact with the side surface of the vehicle to be cleaned, and the side brush main body 50A is tilted and a right inclination detection sensor (not shown). .) Operates, the traveling motor 28 is stopped and the traveling of the left traveling holder 22A is stopped. Thus, the travel is stopped in a state where the side brush body 50A is tilted to the right (outside), and the side surface of the vehicle to be cleaned is cleaned in the tilted state. In such a cleaning state, when the side brush main body 50A is pressed more strongly due to the side shape of the vehicle to be cleaned, an oblique stop, or the like, and swings (tilts) more greatly, the holding cylinder 44 is controlled to swing. Abutting on the body 39, the swinging is restricted. The same operation is performed even when the holder main body 27 of the right traveling holder 22B is traveling right in the closing direction.

In the cleaning operation as described above, the water accumulated in the inner cylinder member 46 can be drained appropriately at any time by opening the plug member 49 by a rotating operation or the like.
