Description

  The present invention relates to a car wash machine installed in a gas station, for example, and used for car wash, and more particularly to a car wash machine provided with a rotating brush for washing a side surface of a vehicle to be cleaned.

  2. Description of the Related Art Conventionally, a car wash machine installed at a fueling station or the like is designed to inject a liquid agent or wash water stored in a liquid storage tank into a car to be washed while moving the car to be washed and the car washer main body in the front-rear direction. It is set as the structure which performs. Further, brushing and cleaning while spraying a liquid agent and cleaning water, and drying by blowing air after cleaning are performed.

  In the washing step, first, dirt is removed using washing water, then washing is performed using a liquid agent such as shampoo, and further washing is performed using washing water. After this washing process, a drying process is performed in which air is blown from each blowing nozzle and dried. In addition, car washing is performed by appropriately combining liquid agent application processes such as wax and water repellent coating as necessary. In this way, various shampoos, waxes and coats are used as liquid agents used in car washing, and each car wash process is stored in a dedicated liquid storage tank and inserted into the tank. It is injected and consumed according to the process. In addition, an operation panel and a remote panel are provided for selecting a desired mode from a plurality of car wash modes, selecting a type of liquid agent to be used, and setting a predetermined car wash mode. The operation panel is installed in the car wash machine body, but the remote panel is installed at a position away from the car wash machine body, and the remote panel is electrically connected to the operation panel. The car wash machine can be driven by the car wash mode.

  An example of a car wash machine including an operation panel and a remote panel will be described with reference to FIG. This car wash machine WB includes a car wash machine main body 1 that is integrally mounted with a cleaning member having a plurality of brushes, and a drying member having a blower and a plurality of blower nozzles, and has a gate shape so as to straddle the vehicle to be cleaned CA. The liquid agent stored in the plurality of liquid storage tanks is diluted with water and sprayed to the vehicle to be cleaned while relatively moving the vehicle to be cleaned CA and the car wash machine body 1 in the front-rear direction. The vehicle to be cleaned is washed.

  For example, the car wash machine main body 1 is configured to travel and move along the rails 2 via the wheels 3, and the pair of left and right rails of the car wash machine in which the vehicle to be cleaned CA is a gate type straddling the vehicle to be cleaned CA. Set the desired car wash mode on the operation panel 7 installed in the car wash machine body 1 or the remote panel 7A installed at a position away from the car wash machine body 1 and operate the start button. Start the car wash operation.

  The portal-type car wash machine main body 1 is, for example, a top brush 4 that cleans the upper surface of the vehicle CA to be cleaned, and both side surfaces and front and rear surfaces of the vehicle CA to be cleaned as a rotating brush body that cleans the vehicle CA to be cleaned. A pair of left and right side brushes 5 and a pair of left and right rocker brushes 6 for cleaning the lower portions of both side surfaces of the vehicle CA to be cleaned are provided.

  In addition, there are provided various nozzles for spraying cleaning water and various liquid agents used for brushing and a liquid storage tank for storing various liquid agents. A plurality of liquid storage tanks for storing various liquid agents are stored in a tank storage portion 9A provided in the car wash machine body 1, and each nozzle is provided via a distribution piping portion 9B having an electromagnetic on-off valve and a sub-water supply hose. Is distributed. As nozzles for injecting the liquid agent, for example, a first water purification nozzle 11, a first detergent nozzle 12, a second water purification nozzle 13, a water repellent coating nozzle 14, a second detergent nozzle 15, a wax nozzle 16, and the like are disposed. .

  Further, for drying, a blower 20, a freely movable top blower nozzle 21 that blows blown air from the blower 20, and a pair of left and right side blower nozzles 22 are provided. Further, the driving condition of the car wash machine WB is set through the operation panel 7 disposed in the car wash machine body 1 or the remote panel 7A installed at a position away from the car wash machine body 1, and based on the set condition. The car wash machine WB is driven. Reference numeral 8 denotes a sensor for detecting the presence / absence of the vehicle to be cleaned CA and the vehicle height, and for example, a photoelectric sensor or a sonic sensor using ultrasonic waves is preferably used.

  On the operation panel 7 and the remote panel 7A, there are selection buttons for selecting various car washing modes such as a water washing mode, a washing mode using a detergent, a wax mode for applying a wax, and a water repellent mode for coating a water repellent. A brush rotation switch for controlling the number of rotations of the brush, a start / stop button, and the like are provided.

  In addition, the car wash machine main body 1 is separated into a washing machine main body provided with a cleaning member and a dryer main body provided with a drying member, each of which has a gate shape so as to straddle the vehicle CA to be cleaned. There is also known a car wash machine configured to wash the vehicle to be cleaned CA while relatively moving the CA, the washing machine main body, and the dryer main body in the front-rear direction. Even if it is this structure, it is the same that it is provided with various brushes and various nozzles, and is provided with the operation panel 7 or the remote panel 7A.

  In the conventional car wash machine WB described above, the side brush 5 that cleans the side surface, front surface, and rear surface of the vehicle CA to be cleaned is brushed by bringing the brush into contact with the side surfaces of the multiple types of vehicle CA to be cleaned having different vehicle widths. In order to perform brushing around the front or rear surface, it is movable in the left-right direction as viewed from the front side of the vehicle.

  In addition, various devices have been devised to wash the car without damaging equipment such as a door mirror, a fender mirror, and a rear mirror that are mounted protruding from the surface of the vehicle body. For example, when a vehicle shape detection sensor is provided and an equipment from which the vehicle shape detection sensor protrudes is detected, there is a device that reduces the rotational speed of the brush at that position. In addition, there are some which divide the side brush 5 into upper and lower parts and make each of them independently rotatable so as to slow down or stop the rotating brush for brushing a part with the equipment.

  Further, finer control can be performed by dividing the side brush 5 into upper, middle, and lower parts and independently rotating them. However, since it is uneconomical to provide three driving devices for driving the three divided rotating brushes, the first driving device for driving the upper rotating brush and the second driving for driving the lower rotating brush. An intermediate rotating brush has already been applied for, for example, a car wash machine in which the driving force of the second driving device is stopped by rotation via a connecting member (expansion / contraction member) using fluid (pressurized air). It has been proposed by a person (for example, see Patent Document 1).

  Further, a car wash rotary brush device in which the upper rotary brush and the lower rotary brush are fixed to the drive shaft and the intermediate rotary brush is coupled to the upper rotary brush via magnetic means has already been disclosed (for example, Patent Document 2). reference).

JP 2009-173175 A Japanese Utility Model Publication No. 60-54426

  By spraying a cleaning liquid such as cleaning water or detergent under high pressure, the surface of the vehicle body can be cleaned and cleaned. Further, by brushing with a rotating brush and washing the car, a higher quality finish can be obtained. However, if the rotating brush hits the equipment protruding from the surface of the vehicle body such as a door mirror or fender mirror too much, there is a risk of damaging it. It is preferable to stop the operation.

  Further, even in a part where the equipment is present, it is preferable to brush and wash the other parts than the equipment. For this purpose, a rotating brush having a rotating shaft in the vertical direction is divided into a plurality of upper, middle, and lower parts, each of which is rotationally controlled individually, the equipment is confirmed using a sensor, and it is in a position corresponding to the confirmed part. It is required to control the rotation of the rotating brush and to wash the car safely without damaging the equipment.

  Moreover, as described in Patent Document 1, the intermediate rotating brush is made contactable and disengageable from the drive shaft using a connecting member (expansion and contraction member) using pressurized air, and two drive devices are used. The configuration in which the rotation of the upper, middle, and lower rotating brushes divided into three is controlled is not preferable because there is a problem in the durability of the cut-off body, and the maintenance cost increases. In addition, since high-pressure air is used, it is necessary to provide a path for sending high-pressure air to the rotating brush body that moves and cleans, which is not preferable.

  Since the rotating brush device described in Patent Document 2 is connected to a rotating rotating brush body through magnetic means and rotates, it is difficult to adjust the contact force applied to the equipment protruding from the surface of the vehicle body. For example, if the magnetic force is too strong, the contact with the equipment becomes too strong, causing a problem. On the other hand, if the magnetic force is too weak, it becomes difficult to transmit the rotational force, and a sufficient cleaning effect cannot be exhibited, which is a problem.

  For this purpose, the rotary brush body is divided into three parts, upper, middle and lower, and fewer than three, for example, two drive devices are used, and the rotation of each rotary brush is controlled without using a fluid such as high-pressure air. It is preferable that the car wash machine be capable of demonstrating the cleaning ability by reliably rotating each rotating brush.

  In view of the above problems, the present invention makes it possible to control the rotation of each rotating brush body of a three-part rotating brush body with a simpler configuration, and has a cleaning capability without damaging equipment such as side mirrors.

It is characterized in that it is connected to the drive shaft of the drive section via a clutch member that does not transmit drive force.

  According to this configuration, the upper rotary brush can control the rotational drive via the first drive unit, and the lower rotary brush can control the rotary drive via the second drive unit. Further, the intermediate rotating brush can be mechanically turned on / off according to the direction of forward / reverse rotation of the drive shaft connected to the clutch member included in the intermediate rotating brush. Therefore, rotation of each rotary brush can be controlled with a simpler configuration without using a fluid such as high-pressure air. In addition, it is possible to easily stop rotating brushes in parts with equipment such as side mirrors, and in parts without equipment, use a car washer that can rotate each rotating brush reliably and demonstrate its cleaning ability. Can be obtained.

  According to the present invention, in the car wash machine having the configuration described above, the clutch member includes a ratchet mechanism including a rolling element having ratchet teeth on an outer periphery thereof and an engaging claw portion that engages with the ratchet teeth. The moving body is incorporated in the drive shaft and rotates concentrically with the drive shaft, and the engaging claw portion is a cylindrical shaft that is fitted around the outer periphery of the drive shaft. It is provided inside and is biased toward the ratchet teeth. According to this configuration, when the drive shaft is in the forward rotation direction, the engagement claw portion engages with the ratchet teeth and the intermediate rotation brush rotates, and when the drive shaft is in the reverse rotation direction, the engagement claw portion and the ratchet By assembling so that the teeth do not engage with each other, the rotation and stop of the intermediate rotating brush can be mechanically controlled.

  According to the present invention, in the car wash machine configured as described above, the rolling element has a columnar shape and includes wide ratchet teeth corresponding to the height of the columnar shape, and the engaging claw portion is associated with the wide ratchet teeth. It is a wide claw member to be combined. According to this structure, since the ratchet mechanism with high strength is configured, a clutch member capable of stably rotating the rotary brush can be obtained.

  According to the present invention, in the car wash machine configured as described above, the drive shaft is a second drive shaft included in the second drive unit, and the intermediate rotating brush is connected to the second drive shaft via the clutch member. It is characterized by being. According to this configuration, the on / off control of the intermediate rotating brush can be switched according to the rotation direction of the second driving unit that drives the lower rotating brush, and the intermediate rotating brush can be rotated together with the lower rotating brush. It is also possible to reliably stop the intermediate rotating brush by rotating the rotating brush.

  According to the present invention, in the car wash machine configured as described above, the second drive shaft is an inner shaft disposed through the brush shaft of the rotating brush body, and the first drive portion is rotationally driven by the first drive portion. The drive shaft is an outer shaft that is rotatably fitted to the inner shaft. According to this configuration, the upper rotary brush is driven to rotate using the outer shaft as a drive shaft, and the lower rotary brush and the intermediate rotary brush are rotated using the inner shaft that is rotatable through the inside of the outer shaft as a drive shaft. Can be driven. Further, since the ratchet mechanism is provided on the inner shaft, the outer diameter of the rolling elements forming the ratchet mechanism can be kept small, and a compact clutch member configuration can be obtained.

  According to the present invention, in the car wash machine having the three-part rotary brush body, the intermediate rotary brush is a first drive unit that rotationally drives the upper rotary brush, or a second drive unit that rotationally drives the lower rotary brush. The drive unit is rotated through a clutch member that rotates in response to one of the rotational drive forces, transmits the rotational drive force in one forward rotational direction, and does not transmit the rotational drive force in the reverse direction. Since it is configured to be connected to the shaft, rotation of each rotary brush can be controlled with a simpler configuration without using a fluid such as high-pressure air. In addition, it is possible to easily stop rotating brushes in parts with equipment such as side mirrors, and in parts without equipment, use a car washer that can rotate each rotating brush reliably and demonstrate its cleaning ability. Can be obtained.

  Embodiments of the present invention will be described below with reference to the drawings. Moreover, the same code | symbol is used about the same structural member, and detailed description is abbreviate | omitted suitably.

  The car wash machine WA according to the present embodiment is a car wash machine that performs a car wash of the vehicle to be cleaned while relatively moving the car wash machine main body and the vehicle to be cleaned in the front-rear direction, and is described above with reference to FIG. It is set as the same structure. For this purpose, as shown in FIG. 6, a top for cleaning the upper surface of the vehicle CA to be cleaned as a rotary brush body for brushing and cleaning the main body 1 of the car-type car that travels and moves along the rails 2 via the wheels 3. The brush 4 is provided with a pair of left and right side brushes 5 for cleaning the both side surfaces and front and rear surfaces of the vehicle CA to be cleaned, and a rocker brush 6 for cleaning the undercarriage of the vehicle CA to be cleaned. The structure provided with the top ventilation nozzle 21 which can be raised / lowered which blows the ventilation from the blower 20, and the left-right paired side ventilation nozzle 22 is the same.

  8A is a bonnet height detection sensor for detecting the hood height of the vehicle CA to be cleaned. Like the sensor 8 for detecting the presence / absence of the vehicle CA to be cleaned and the vehicle height, a photoelectric or ultrasonic reflection is provided. A type sensor can be used. In addition, it is possible to detect the presence / absence of the vehicle CA to be cleaned and the height of the bonnet by using one sensor in consideration of the arrangement positions of these sensors.

  Further, instead of the bonnet height detection sensor 8A, a vehicle shape detection sensor (not shown) made of a transmission type photoelectric sensor can be used. In this case, a projector is provided in the vertical direction on one side of the car wash machine main body, and a light receiver is provided in the vertical direction on the other side opposite to these projectors, thereby entering the cleaning position. It detects the vehicle shape and bonnet height of the vehicle to be cleaned.

  The pair of left and right side brushes 5 are supported on a traveling rail disposed in the width direction of the upper portion of the car wash machine body 1 so as to be movably suspended in the left-right direction as viewed from the front side of the vehicle to be cleaned, and Each brush shaft is configured to be rotatably supported by each traveling holder. For example, as shown in FIG. 4, the right side brush 5A on the right side is rotatably supported by the first traveling holder 50A, and the left side brush 5B on the left side is rotatably supported by the second traveling holder 50B. ing.

  Each of the right side brush 5A and the left side brush 5B is suspended in a swingable manner via the swing support portion 60, and travels through the respective travel holders (first travel holder 50A, second travel holder 50B). It is configured such that it can reciprocate along the rail 30. Further, the brush shaft can be rotated by a separately provided rotational drive motor. Therefore, the brush can be rotated in a state where the brush is inclined and brought into contact with the inclined side surface portion of the vehicle to be cleaned. That is, the side brush 5 (5A, 5B) can be brushed by matching with the side surface portion of the vehicle to be cleaned.

  Further, since the first traveling holder 50A and the second traveling holder 50B can travel independently from each other, even if the position of the vehicle to be cleaned with respect to the car wash machine body 1 in the left-right direction is shifted, The brushes 5A and 5B are arranged at appropriate positions to exhibit a desired cleaning effect, thereby enabling stable car washing.

  When cleaning the side surfaces of the vehicle CA to be cleaned using the side brushes 5 (5A, 5B) suspended so as to be swingable via the swing support portion 60, for example, the respective side brushes 5 are covered. After making contact with the side surface of the washing vehicle CA and further advancing it a little and tilting it at a predetermined angle via the swing support part 60, each side brush 5 is rotated at a position where the inclination is reduced by returning a predetermined distance. , Carrying out the car washing on each side at the same time, reducing the pressing strength on the side of the car body. At this time, in order to maintain the inclined posture to be washed, the pressing force may be obtained by using the biasing force of the weight.

  The traveling rail 30 has an end shaft supported by a bearing body 41, and is configured to be swingable in the front-rear direction of the vehicle via a driving device (not shown). Moreover, the front-back inclination detection sensor 42 is provided, and it is set as the structure which detects the inclination of the front-back direction via this sensor.

  The right side brush 5A on the right side slides and moves in the direction of arrow D1 in the figure through the first traveling holder 50A, and the left side brush 5B on the left side in the figure passes through the second traveling holder 50B. It is configured to open and close the pair of left and right side brushes 5 with respect to both sides of the vehicle to be cleaned by sliding and moving in the direction D2.

  As shown in the drawing, each traveling holder 50A, 50B is slidable along the traveling rail 30 on the holder main body 31, a traveling motor 32, a traveling wheel 33 driven by the traveling motor 32, and the traveling holder. And a guide roller 34 to be supported. In addition, a drive member that rotationally drives the brush shaft of the side brush 5, a swing support portion 60 that supports the brush shaft in a swingable manner, and a swing angle detection sensor that detects the swing angle of the brush shaft. Yes.

  The swing support portion 60 may have any configuration as long as the brush shaft is configured to rotatably and swingably support the brush shaft. For example, the support portion that rotatably supports the brush shaft may be configured to be swingable integrally. Alternatively, the brush shaft may be configured to have a dual configuration of a rotation shaft and a fixed shaft, and the fixed shaft may be swingably supported. The rotary shaft can be rotatably mounted inside the fixed shaft.

  Although not shown, an open limit sensor or a close limit sensor that defines the limits of the opening and closing directions of the first traveling holder 50A and the second traveling holder 50B can be provided.

  By using the side brush 5 (5A, 5B) having the above-described configuration, the traveling holders 50A, 50B can be slid along the traveling rail 30, and the pair of left and right side brushes 5 can be opened and closed left and right. . Further, it is possible to stop each side brush 5 in contact with the side surface of the vehicle and swing it by a predetermined angle, or to separate it from the vehicle by a predetermined return distance after the stop.

  For example, as shown in FIG. 5, when the vehicle CA to be cleaned stops at a predetermined position of the car wash machine body 1 and the car wash starts, the right side brush 5A moves in the direction of the arrow D1 in the drawing via the first travel holder 50A. The left side brush 5B on the left side is slid in the direction of the arrow D2 in the drawing via the second traveling holder 50B, and the pair of left and right side brushes 5 are placed on both sides of the vehicle to be cleaned. Start cleaning with contact and brushing.

  Further, the car wash machine main body 1 moves along the rail 2 while brushing, so that the entire length of the vehicle CA of the vehicle to be cleaned is brushed and cleaned.

  At this time, if the rotating brush hits the equipment protruding from the surface of the vehicle body such as a door mirror or a fender mirror too much, there is a risk of damaging it. The upper rotary brush 51, the intermediate rotary brush 52, and the lower rotary brush 53 are configured so that each rotary brush can be controlled on and off. With this configuration, when brushing a part with equipment, it is preferable that the rotation can be easily slowed or stopped.

  For example, as shown in FIG. 5, when the door mirror 80 is detected, the rotation of the intermediate rotating brush 52 corresponding to this portion is stopped, and the other portions are brushed and washed.

  Next, regarding the three-part rotary brush body according to the present embodiment, the configuration of the side brush 5 having a three-part configuration in the upper, middle, and lower portions will be described with reference to FIGS. 1 and 2.

  As shown in FIG. 1, the side brush 5 supported in a suspended state on the traveling rail 30 via the traveling holder 50 (50 </ b> A, 50 </ b> B) includes an upper rotating brush 51, an intermediate rotating brush 52, and a lower rotating brush 53. The three-part brush configuration is provided.

  The upper rotating brush 51 includes a first driving unit DV1 including a first driving motor M1, a driving gear G1, a driven gear P1, and a driving force transmission body (for example, a chain or a timing belt) wound around these gears. It is rotationally driven by.

  The lower rotating brush 53 includes a second driving unit DV2 including a second driving motor M2, a driving gear G2, a driven gear P2, and a driving force transmitting body (for example, a chain or a timing belt) wound between these gears. It is rotationally driven by.

  The intermediate rotating brush 52 rotates in response to the rotational driving force of either the first or second driving unit, transmits the rotational driving force in one positive rotational direction, and rotates in the reverse direction. It is connected with the drive shaft of the said drive part via the clutch member CL which does not transmit drive force.

  The clutch member CL may be configured to have a function of transmitting or not transmitting the rotation depending on the rotation direction of the drive shaft. For example, the clutch member CL transmits a rotational driving force when the drive shaft is rotating in the forward direction and performs intermediate rotation. When the brush 52 rotates and the drive shaft rotates in the reverse direction, the rotational driving force is not transmitted, and the intermediate rotating brush 52 stops without rotating. Therefore, as this clutch member CL, a one-way clutch, a ratchet mechanism provided with ratchet teeth and an engaging claw, or the like can be used.

  In the present embodiment, the clutch member CL including a ratchet mechanism including a rolling element 61 having ratchet teeth on its outer periphery and an engaging claw portion 62 that engages with the ratchet teeth is used. The rolling element 61 is incorporated in the drive shaft and rotates concentrically with the drive shaft. The engaging claw 62 is provided on the inner side of the brush shaft BT1 of the intermediate rotating brush 52 that is a cylindrical shaft that is fitted on the outer periphery of the drive shaft, and is biased toward the ratchet teeth.

  A ratchet mechanism including a rolling element 61 having ratchet teeth and an engaging claw portion 62 is preferable because it can easily cope with a relatively large rotating body such as a side brush equipped in a car wash machine. Also, with this configuration, when the drive shaft is in the forward rotation direction, the engagement claw portion 62 is engaged with the ratchet teeth and the intermediate rotary brush 52 is rotated, and when the drive shaft is in the reverse rotation direction, the engagement claw portion 62 is engaged. By assembling so that the claw portion 62 and the ratchet teeth are not engaged, the rotation and non-rotation (stop) of the intermediate rotating brush 52 can be mechanically controlled.

  For example, as shown in FIG. 2A, when the rolling element 61 rotates together with the drive shaft in the direction of the arrow K1 in the figure, it is provided with a support shaft 62a and a ratchet spring 62b so as to be biased toward the rolling element 61. The engaging claw portion 62 configured as described above is engaged with the ratchet teeth 61 a to be in a rotational driving force transmission state, and the intermediate rotating brush 52 rotates together with the rolling element 61.

  Further, as shown in FIG. 2B, when the rolling element 61 rotates in the direction of the arrow K2 in the drawing together with the drive shaft, the ratchet teeth 61a rotate in the direction in which the engaging claw 62 does not engage, Even if the engaging claw 62 is urged toward the ratchet teeth 61a, the engaging claw portion 62 is not engaged and the rotational driving force is not transmitted, and the intermediate rotating brush 52 stops without rotating.

  Thus, the intermediate rotating brush 52 is switched between a rotating state and a non-rotating state depending on the rotating direction of the rolling element 61 that rotates together with the drive shaft. That is, the rotation and non-rotation of the intermediate rotary brush 52 can be controlled by switching the rotation direction of the drive shaft.

  The drive shaft for rotating the intermediate rotating brush 52 may be a drive shaft provided in the first drive unit DV1 or a drive shaft provided in the second drive unit DV2. Further, the intermediate rotary brush 52 itself is connected to the drive shaft of the drive unit via a clutch member CL that transmits the rotational drive force in one forward rotational direction and does not transmit the rotational drive force in the reverse direction. There is no need to provide an independent drive unit.

  Here, in this embodiment, as shown in FIG. 1, it is set as the structure which connects the intermediate | middle rotating brush 52 via the clutch member CL to 2nd drive shaft DS2 which 2nd drive part DV2 has. That is, the second drive shaft DS2 rotationally drives the lower rotary brush 53 via the connector RG, and the intermediate rotary brush 52 rotates along with the forward rotation of the lower rotary brush 53 via the clutch member CL, and in the reverse direction. It becomes a structure which does not rotate at the time of rotation.

  BT1 in the drawing is a brush shaft of the intermediate rotating brush 52, and is attached to the second drive shaft DS2 via the bearing member BG3 while mounting the engaging claw portion 62 described above. BT2 is a brush shaft of the lower rotary brush 53, and is connected to the second drive shaft DS2 via a connector RG. Also. The brush shaft of the upper rotary brush 51 may be configured to serve as the first drive shaft DS1, or may be configured to be attached to the first drive shaft DS1.

  The second drive shaft DS2 is an inner shaft that passes through the brush shaft of the side brush 5, and the first drive shaft DS1 that is rotationally driven by the first drive portion DV1 is rotatably fitted on the outside thereof. Is done. That is, the first drive shaft DS1 is an outer shaft and is assembled to the second drive shaft DS2 of the inner shaft via the bearing members BG1 and BG2 so as to be relatively rotatable. With this configuration, the upper rotary brush 51 is rotationally driven using the outer shaft as a drive shaft, and the lower rotary brush 53 and the intermediate rotary brush 52 are driven using an inner shaft that passes through the outer shaft and is rotatable. Are driven to rotate. Further, since the ratchet mechanism is provided on the second drive shaft DS2 serving as the inner shaft, the outer diameter of the rolling elements 61 forming the ratchet mechanism can be kept small, and a compact clutch member configuration can be obtained.

  The rolling element 61 provided in the clutch member CL is formed in a columnar shape and includes wide ratchet teeth 61a corresponding to the columnar height. Therefore, the engaging claw portion 62 is a wide claw member that engages with the wide ratchet teeth 61a. With this configuration, a high-strength ratchet mechanism is configured, so that the durability is improved and the clutch member CL is capable of stably rotating the rotary brush.

  Since the clutch member CL is used, the turning on / off of the intermediate rotating brush 52 can be controlled mechanically. Therefore, it is preferable to have a simple configuration that does not require an electrical member or a fluid member for rotation control.

  For example, as shown in the schematic diagram of FIG. 3, when brushing the side surface of the vehicle CA to be cleaned using a three-part rotary brush body, when cleaning the side mirror 80, the direction of the arrow K2 as described above. Then, the rotation of the intermediate rotating brush corresponding to the portion where the side mirror 80 is located is stopped. Further, when brushing a portion other than the side mirror 80, the brush shaft is rotated in the direction of the arrow K1, and the brush is rotated by rotating all of the three-part side brushes.

  As described above, the three-part rotary brush body included in the car wash machine WA according to the present invention has been described using the side brush 5 divided into the upper, middle, and lower sides. A rotating brush body may be used. The three-part rotary brush body according to the present embodiment can reliably control the rotation and non-rotation of each rotary brush, so that the part protruding from the vehicle body surface and the equipment is disposed and the other flat vehicle body surface Can be used particularly suitably as a rotating brush body that is simultaneously brushed and cleaned.

  As described above, the car wash machine WA according to the present embodiment includes the rotary brush body (for example, the side brush 5) divided into three parts, and the intermediate rotary brush 52 rotates and drives the upper rotary brush 51. The drive unit or the second drive unit that rotationally drives the lower rotary brush 53 is rotated by receiving the rotational drive force, and the rotational drive force is transmitted in one positive rotational direction, and in the opposite direction. Is configured to be connected to the drive shaft of the drive unit via a clutch member CL that does not transmit rotational drive force, so that each rotary brush can be rotated with a simpler structure without using a fluid such as high-pressure air. Can be controlled. In addition, it is possible to easily stop the rotating brush in the part with the equipment such as the side mirror, and in the part without the equipment, the respective rotating brush is reliably rotated to obtain a car washing machine that exhibits the cleaning ability. be able to.

  The clutch member CL includes a ratchet mechanism that includes a rolling element 61 that has ratchet teeth on its outer periphery and rotates together with the drive shaft, and an engagement claw portion 62 that is urged toward the ratchet teeth to engage. Therefore, when the drive shaft is in the forward rotation direction, the engagement claw portion 62 is engaged with the ratchet teeth and the intermediate rotary brush 52 is rotated.
