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 and a car wash method for washing a side surface, a front surface, and a rear surface of a vehicle to be cleaned while moving a side brush.

  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 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 WA is equipped with 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 a pair of left and right surfaces that clean both side surfaces and front and rear surfaces of the vehicle CA to be cleaned. Side brush 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.

  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 unit 60 provided in the car wash machine body 1, and each nozzle is provided via a distribution pipe unit 61 including 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. In addition, the driving condition of the car wash machine WA is set via 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 WA 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 in this configuration, it is the same that various brushes and various nozzles are provided and the operation panel 7 or the remote panel 7A is provided.

  In the above-described conventional car wash machine WA, the side brush 5 for cleaning 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 brush around the front and rear surfaces, it is movable in the front-rear and left-right directions as viewed from the front side of the vehicle.

  For this purpose, a pair of left and right side brushes are attached to the car wash machine main body in a suspended state through a brush shaft, and the brush shaft is supported so as to be swingable and rotatable. Various measures have been taken to wash the vehicle without damaging equipment such as door mirrors, fender poles, and rear mirrors that protrude from the vehicle body surface. 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 is also a device in which the equipment portion detected by the vehicle shape detection sensor is moved so as to be retracted so that the brush does not directly contact.

  Further, when the front and rear surfaces of the vehicle to be cleaned are washed using the side brush, it is detected from the inclination of the side brush that the side brush is in contact with the vehicle body. For example, first, a pair of left and right side brushes are brought into contact with the front portion of the vehicle to be cleaned and gradually opened while rotating in this contacted state, and the front surface is washed. When it reaches the side, it keeps its open state and cleans the side while moving forward, it reaches the rear as it is, and on the rear side, it stops running and the pair of left and right side brushes return to the closed state again. is doing.

  When shifting from the side-washing state to the rear-side washing, the pair of left and right side brushes that are in contact with the vehicle body with a predetermined pressing force are displaced so as to suddenly turn inward, and this places a burden on the side brush. Therefore, in order to reduce the burden on the side brush, for example, once the side brush reaches the rear surface, the side brush is once fully driven to move forward and away from the vehicle body, and then fully closed to drive back in the closed state. There has already been proposed a side brush control method in a car wash machine that comes into contact with the rear surface and starts washing the rear surface (see, for example, Patent Document 1).

  In addition, in order not to contact the vehicle body with an excessive pressing force, when the swing angle of the side brush is detected and a predetermined set angle is reached, the relative movement between the car washer and the vehicle to be cleaned is stopped. A car wash machine has already been proposed (see, for example, Patent Document 2).

JP-A-6-171476 Japanese Patent No. 3778014

  By bringing the pair of left and right side brushes into contact with the vehicle body surface and inclining at a predetermined angle, the contact force of the side brush can be regulated within a predetermined range, and a good car wash finish can be obtained. Further, by detecting the inclination of the side brush above a predetermined level and stopping the traveling movement of the car wash machine body, it is possible to prevent damage to the vehicle body surface and the equipment protruding from the vehicle body surface.

  However, when the side brush is tilted more than a predetermined amount, the vehicle washing process is interrupted only by stopping the traveling of the car wash machine main body, resulting in a long car washing time. Further, it is preferable to control not only the magnitude of the inclination but also the magnitude of the shake of the side brush to reduce the shake amount.

  In particular, when a general user uses a car wash, if the side brush that washes the side of the vehicle while rotating during the car wash is shaken, anxiety about the car wash increases, and the car wash effect is questionable. It arises and becomes a problem.

  In addition, since the side brush is swingably suspended, the side brush comes into contact with the side surface of the vehicle and tilts in the left-right direction (the width direction of the vehicle to be cleaned). Moreover, it may incline in the front-back direction (the length direction of the vehicle to be cleaned). In addition, there is a case where the camera shakes greatly in the left-right direction and in the front-rear direction due to interference with the frame and equipment. In particular, this large fluctuation in the front-rear direction is undesirable because it may damage the vehicle and equipment or cause an abnormal stop.

  Therefore, when a large shake occurs in the front-rear direction of the side brush that performs car washing while rotating, it is preferable to detect the shake and immediately suppress and stabilize the shake. Moreover, it is preferable not to deteriorate the car wash efficiency by enabling the side brush shake to be suppressed while exhibiting the car wash effect without stopping the car wash process.

  In view of the above problems, the present invention effectively suppresses side brush shake in a car wash machine including a side brush that brushes the side of a vehicle body, exhibits a predetermined car wash effect, and further deteriorates car wash efficiency. An object of the present invention is to provide a car wash machine and a car wash method that can be washed without any trouble.

  In order to achieve the above object, the present invention is a car wash machine having a side brush for washing a vehicle to be washed and performing car washing while moving the vehicle to be washed and a car wash machine body in the front-rear direction, and the side brush Is a brush shaft that is supported in a suspended state rotatably through a traveling holder that is reciprocally mounted in the width direction of the upper portion of the car wash machine body, and a forward / backward tilt that detects the forward / backward inclination of the brush shaft. A first determination that determines whether or not the brush shaft shake detected by the front-rear tilt angle detector is larger than a predetermined first shake. And low-speed rotation control for reducing the rotation speed of the brush shaft for a predetermined time when it is determined by the control and the first determination control that the magnitude of the blur is larger than the first blur. .

  According to this configuration, even when the side brush suspended while swinging is swung while the side surface of the vehicle to be cleaned is cleaned using the side brush, the side brush is By reducing the rotational speed, the shake can be quickly suppressed. In addition, since the rotation of the brush continues, a predetermined car wash effect is exhibited, and a car wash machine capable of car wash without deteriorating car wash efficiency can be obtained.

  According to the present invention, in the car wash machine having the above-described configuration, after the low-speed rotation control, continuous determination control for detecting the shake of the brush shaft again is performed, and the magnitude of the shake is determined by the continuous determination control. If it is detected that the rotational speed is smaller than the first shake, the rotational speed return control is performed to increase the brush shaft to a predetermined operation speed. It is characterized by performing continuous low-speed rotation control to continue the operation. According to this configuration, the reduction in the rotational speed of the brush shaft is performed for a predetermined time, so that the car wash efficiency is not deteriorated. In addition, since shake detection is repeatedly performed and promptly dealt with, it is possible to easily cope with sudden shake of the side brush and reduce the shake.

  According to the present invention, in the car wash machine configured as described above, the forward / backward tilt angle detection unit includes a first shake detection sensor that detects the first shake of the brush shaft, and a second shake larger than the first shake. A second shake detection sensor for detecting rotation, and when the second shake is detected via the second shake detection sensor, rotation stop control is performed to stop rotation by determining an abnormality. It is said. According to this configuration, when the side brush generates a second shake larger than the first shake, it is regarded as abnormal and the rotation is stopped, so that it is possible to prevent damage to the vehicle to be cleaned and the car wash machine.

  In the car wash machine having the above-described configuration, the present invention further includes a left / right tilt angle detection unit that detects the tilt of the brush shaft in the left / right direction, and the side brush is inclined at a predetermined angle via the left / right tilt angle detection unit. The first and second shake detection is performed by the front / rear tilt angle detection unit while washing the vehicle while being brought into contact with the side surface of the vehicle to be cleaned. According to this configuration, even if a shake that shakes in the front-rear direction occurs during cleaning by pressing the side brush against the side of the vehicle to be cleaned, low-speed rotation control is performed for a predetermined time for the relatively small first shake, The blur can be quickly suppressed. In addition, when a relatively large second shake occurs, the rotation can be stopped immediately to prevent damage to the vehicle to be cleaned and the car wash machine.

  According to the present invention, in the car wash machine configured as described above, the side brush includes a left side brush and a right side brush, and the right side brush is supported by a first traveling holder that is movable along the traveling rail. The left side brush is supported by a second traveling holder, and these traveling holders are capable of sliding along the traveling rail with a traveling motor, traveling wheels driven by the traveling motor, and the traveling holder. Each of which includes a guide roller to be supported, each provided with the left / right tilt angle detection unit and the front / rear tilt angle detection unit, and individually detecting the magnitude of shake of each of the brush shafts and individually determining the rotation speed thereof. It is characterized by control. According to this configuration, even when the side brush is washed with the side brush and one side of the pair of left and right side brushes swings freely, the side brush rotates for a predetermined time. By reducing the number, the blur can be suppressed. In addition, the brush with the less shake is at the normal rotation speed, and the brush with the greater shake is at a rotation speed lower than the normal rotation so that the brush rotation continues and the predetermined car wash effect is exhibited, and the car wash efficiency is not deteriorated. The car can be washed.

  Further, the present invention is a car wash method for a car wash machine having a side brush for washing a car to be washed, and performing car wash while moving the car to be washed and the car wash machine body in the front-rear direction, the side brush being a car wash A brush shaft that is supported in a suspended state rotatably through a traveling holder that is reciprocally mounted in the upper width direction of the machine body, and a forward / backward tilt angle detection unit that detects the forward / backward inclination of the brush shaft. And a first determination control for determining whether or not the brush shaft shake detected via the front / rear tilt angle detector is larger than a predetermined first shake; When it is determined that the magnitude of the shake is larger than the first shake by one determination control, low-speed rotation control is performed to reduce the rotation speed of the brush shaft for a predetermined time, and after the low-speed rotation control, the brush Shake the shaft again Rotation speed return control for performing continuous detection control to detect, and when the continuous determination control detects that the magnitude of the shake is smaller than the first shake, the brush shaft is increased to a predetermined operation rotational speed. When it is detected again that it is larger than the first shake, the continuous low-speed rotation control for continuing the low-speed rotation for a predetermined time is performed again, and the side brush comes into contact with the side surface of the vehicle to be cleaned for cleaning. The car wash is continued while the vibration of the brush shaft generated in step 1 is quickly attenuated.

  According to this configuration, even when the pair of left and right side brushes that are suspended so as to be swingable are shaken, the shake can be quickly suppressed by reducing the rotation speed for a predetermined time. Further, the deceleration time is a predetermined time, and even if the deceleration control is performed, the rotation of the brush continues, so that a predetermined car washing effect is exhibited, and a car washing method capable of car washing without deteriorating the car washing efficiency can be obtained.

  According to the present invention, in the car wash method having the above-described configuration, the forward / backward tilt angle detection unit includes a first shake detection sensor that detects the first shake of the brush shaft, and a second shake larger than the first shake. A second shake detection sensor for detecting rotation, and when the second shake is detected via the second shake detection sensor, rotation stop control is performed to stop rotation by determining an abnormality. It is said. According to this configuration, when the side brush generates a second shake larger than the first shake, it is regarded as abnormal and stops rotating, so that it is possible to prevent damage to the vehicle to be cleaned and the car wash machine. Become a method.

  According to the present invention, when the side brush is swung freely while washing the side surface of the vehicle to be cleaned using the side brush, control is performed to reduce the rotational speed for a predetermined time. The blur can be quickly suppressed. Further, since the rotation of the brush continues, a car wash machine and a car wash method that exhibit a predetermined car wash effect and can be washed without deteriorating car wash efficiency 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 of 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 main body and the vehicle to be cleaned in the front-rear direction, as described above with reference to FIG. The top-type brush 4 that cleans the top surface of the vehicle to be cleaned CA and the both side surfaces and the front and back surfaces of the vehicle to be cleaned CA are cleaned on the main body 1 of the car-type car that travels along the rails 2 via the wheels 3. A pair of left and right side brushes 5 and a pair of left and right rocker brushes 6 that wash the undersides of both side surfaces of the vehicle CA to be cleaned. The blower 20 and the blower 20 can be blown up and down for drying. It is the structure provided with the right top ventilation nozzle 21 and the pair of left and right side ventilation nozzles 22.

  As shown in FIG. 6, the pair of left and right side brushes 5 are suspended on a traveling rail 30 disposed in the width direction of the upper portion of the car wash machine body 1 so as to be movable in the left-right direction as viewed from the front side of the vehicle to be cleaned. Each brush shaft 52 is supported in a lowered state and is rotatably supported by each traveling holder. For example, as shown in the figure, the first (right) side brush 5 is rotatably supported by the first traveling holder 50A, and the second (left) side brush 5 is rotatably supported by the second traveling holder 50B. Has been.

  Each of the pair of left and right side brushes 5 is suspended so as to be swingable via a swing support portion 51 and is attached to the travel rail 30 via the respective travel holders (first travel holder 50A, second travel holder 50B). It is set as the structure which can be reciprocated along. Further, the brush shaft 52 can be rotated by a separately provided rotation driving 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 CA. That is, the side brush 5 can be brushed by matching with the inclined side surface portion of the vehicle CA to be cleaned.

  Further, since the first traveling holder 50A and the second traveling holder 50B can travel independently of each other, the first traveling holder 50A and the second traveling holder 50B can perform the first traveling even if the left and right positions of the vehicle to be cleaned are shifted with respect to the car wash machine body 1. The holder 50A is moved in the direction of the arrow D11, the second traveling holder 50B is moved in the direction of the arrow D12, and the left and right side brushes 5 and 5 are arranged at appropriate positions to exhibit a desired cleaning effect, and are stable. Car wash is possible.

  When cleaning the side surface of the vehicle CA to be cleaned using the side brush 5 that is suspended so as to be swingable via the rocking support 51, for example, the side brush 5 is cleaned with the side surface of the vehicle CA to be cleaned. Then, it is further moved forward and rotated while being inclined at a predetermined angle via the swinging support portion 51 for cleaning. In addition, after tilting by a predetermined angle, each side brush 5 is rotated at a position where the tilt is reduced by a predetermined distance to reduce the pressing strength against the side of the vehicle, and each side is washed simultaneously. Sometimes. 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 swing support portion 51 may have any configuration as long as the brush shaft is configured to support the brush shaft so as to be rotatable and swingable. For example, the support portion that rotatably supports the brush shaft 52 may be configured to be swingable integrally. Alternatively, the brush shaft 52 may be configured as a dual configuration of a rotation shaft and a fixed shaft, and the fixed shaft may be swingable. It is also possible to adopt a configuration in which a rotating shaft is rotatably supported inside the fixed shaft.

  Moreover, it can be set as the structure which drives each side brush 5 separately by making it into a two-stage top and bottom type. Further, although not shown, an open limit sensor and a close limit sensor that define respective limits in 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 having the above-described configuration, the traveling holders 50A and 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.

  As described above, since the side brush 5 is swingably suspended, the side brush 5 abuts on the side surface of the vehicle and tilts in the left-right direction (the width direction of the vehicle to be cleaned). Moreover, it may incline in the front-back direction (the length direction of the vehicle to be cleaned). In addition, there is a case where the camera shakes greatly in the left-right direction and in the front-rear direction due to interference with the frame and equipment. In particular, if the shake in the front-rear direction is large, it is not preferable because it may damage the vehicle or equipment or cause an abnormal stop.In this embodiment, the magnitude of the shake in the front-rear direction is detected. In this configuration, blurring of a predetermined size or more is suppressed.

  Next, the blurring in the front-rear direction that occurs when the side surface of the vehicle CA to be cleaned is washed using the side brush 5 will be described with reference to FIGS. 1 and 2.

  The car wash machine WA shown in FIG. 1 drives the side brush 5 while moving the car wash machine body 1 in the direction of the arrow D1 in the drawing to wash the side surface of the vehicle CA to be cleaned. At this time, since the brush shaft 52 of the side brush 5 is suspended so as to be swingable via the swing support portion 51, the side which is shaken in the front-rear direction depending on the contact state between the side brush 5 and the vehicle side surface. The case where it becomes brush 5A arises.

  Therefore, in this embodiment, a left / right tilt angle detector (not shown) that detects the tilt of the brush shaft 52 in the left / right direction and a front / rear tilt angle detector KS that detects the tilt in the front / rear direction are provided, respectively. When the magnitude of the shake of the brush shaft 52 is detected via the detection unit KS and it is determined that the detected shake is larger than the predetermined first shake, the rotational speed of the brush shaft 52 is decreased by a predetermined time. It is set as the structure which performs control to.

  With this configuration, even when the side brush 5 that is suspended in a swingable manner is shaken during the cleaning of the side surface of the vehicle CA to be cleaned using the side brush 5, the rotational speed is reduced for a predetermined time. Therefore, the blur can be suppressed. Further, since the rotation of the brush continues, a predetermined car washing effect is exhibited, and the car can be washed without deteriorating the car washing efficiency.

  When the rotational speed is decreased for a predetermined time (for example, several seconds), the shake is rapidly attenuated. Therefore, after the rotational speed of the brush shaft 52 is decreased for a predetermined time, the vibration of the brush shaft 52 is detected again, and is less than the predetermined value. It is detected whether or not. When it is detected that the value is equal to or less than the predetermined value, the brush shaft 52 is increased to a predetermined operation rotational speed. In addition, when it is detected again that the value is equal to or greater than the predetermined value, the control is performed to reduce the predetermined time again. If it is such a structure, since the rotation speed reduction of the brush axis | shaft 52 will be performed only for the predetermined time, car wash efficiency will not deteriorate. Further, even if the side brush 5 is suddenly shaken, it is preferable to reduce the number of rotations for a predetermined time to reduce the shake and to deal with it quickly.

  When the shake of the side brush 5 is larger than the first shake, it is assumed that something abnormal has occurred rather than the control for reducing the rotation speed. Therefore, in the present embodiment, as shown in FIG. 2, the first shake detection sensor KS1 and the second shake detection sensor KS2 are provided as the forward / backward tilt angle detection unit KS.

  The first shake detection sensor KS1 detects the first shake (5A shown in the figure) of the brush shaft 52, and the second shake detection sensor KS2 is the second shake (in the figure, larger than the first shake). 5B) shown is detected. Further, when the second shake detection sensor KS2 detects the second shake, it performs a control to determine that it is abnormal and stop the rotation. With this configuration, when the side brush 5 generates a second shake larger than the first shake, it is regarded as abnormal and stops rotating, thus preventing damage to the vehicle to be cleaned CA and the car wash machine WA. This is preferable.

  The pair of left and right side brushes 5 are supported by travel holders that are movable along the travel rails 30. Each of the first and second traveling holders includes a traveling motor, traveling wheels driven by the traveling motor, and a guide roller that slidably supports the traveling holder along the traveling rail. Further, a left / right tilt angle detection sensor for detecting the tilt of the brush shaft in the left / right direction and a front / rear tilt angle detection sensor KS (first shake detection sensor KS1 and second shake detection sensor KS2) for detecting the tilt in the front / rear direction are provided. The amount of shake of the brush shaft 52 is detected and individually controlled via the front / rear tilt angle detection sensor KS. With this configuration, even when the side brush 5 is used to wash the side surface of the vehicle CA to be cleaned and the side brush 5 is shaken, the side brush can be moved. By reducing the rotational speed for a predetermined time, the fluctuation can be suppressed. In addition, the brush with the less shake is at the normal rotation speed, and the brush with the greater shake is at a rotation speed lower than the normal rotation so that the brush rotation continues and the predetermined car wash effect is exhibited, and the car wash efficiency is not deteriorated. It is preferable that the car can be washed.

  During cleaning of the vehicle side surface, for example, as shown in FIG. 3, the traveling holder 50 (first and second traveling holders) that moves along the traveling rail 30 moves in the direction of arrow D <b> 2 in the drawing, and the side brush 5. Abuts against the side of the vehicle. At this time, the brush shaft 52 is configured to be inclined obliquely so that the side brush 5 is in contact with the side surface of the vehicle with a predetermined pressing force.

  Therefore, in this state, if the side brush 5 sways back and forth, there is an increased risk of damaging the vehicle side surface and equipment.

  As in the present embodiment, when the magnitude of the shake of the brush shaft 52 is detected via the first determination control, and the detected shake is determined as the first shake greater than or equal to a predetermined value, the brush shaft 52 When low-speed rotation control is performed to reduce the number of rotations for a predetermined time, even if the side brush 5 slidably swings during the cleaning of the side surface of the vehicle CA to be cleaned using the side brush 5 By reducing the time and the number of revolutions, the shake can be quickly suppressed.

  In addition, since the rotation of the brush continues, a predetermined car wash effect is exhibited, and a car wash machine capable of car wash without deteriorating car wash efficiency can be obtained.

  Next, the car wash method according to the present embodiment will be further described with reference to FIG.

  The car wash method according to the present embodiment includes a pair of left and right side brushes, which are a left side brush and a right side brush that rotate by rotating a brush shaft in the vertical direction in order to clean the side surface of the vehicle to be cleaned. This is a car wash method for a car wash machine that performs car wash while relatively moving a washing vehicle and a car wash machine body in the front-rear direction. Further, the pair of left and right side brushes includes a brush shaft that is supported in a suspended state rotatably through a traveling holder that is reciprocally mounted in the width direction of the upper portion of the car wash machine body. A right and left tilt angle detection unit that detects the tilt of the direction and a front and rear tilt angle detection unit that detects the tilt of the front and rear direction. The first determination control for determining whether or not the first shake is larger than the determined first shake, and the rotation speed of the brush shaft when the first determination control determines that the magnitude of the shake is greater than the first shake. The low-speed rotation control is performed to reduce the vibration for a predetermined time, and after the low-speed rotation control, the continuous determination control is performed to detect the shake of the brush shaft again, and the blur is smaller than the first shake by the continuous determination control. Is detected Rotation speed return control for increasing the brush shaft to a predetermined operation speed is performed, and if it is detected that the brush shaft is larger than the first shake again, continuous low speed rotation control for continuing the low speed rotation for a predetermined time is performed again. The car wash is continued while the brush shaft shake generated when the brush comes into contact with the side of the vehicle to be cleaned for cleaning is quickly attenuated.

  That is, as shown in FIG. 4, the car wash process is started, and the side brush shake amount is detected during the vehicle side face cleaning using the side brush (step S1) (the inclination of step S2 corresponding to the first determination control is small). When the first shake is detected (when “small tilt detection?” In step S2 is Y), the timer t is set in step S5, and a predetermined time (time t seconds) is set. SB low rotation of S6 (corresponding to low-speed rotation control for rotating the side brush at low speed) is performed. On the other hand, if the shake is smaller than the first shake, the process proceeds from step S2 in the direction of arrow N to check in step S3 whether or not the timer t is being measured. The SB high rotation in Step S4 (normal side brush high-speed rotation) is continued.

  After the SB low rotation in step S6 corresponding to the low-speed rotation control is performed for a predetermined time, the process returns to “small inclination detection?” In step S2. In addition, even after the SB high rotation is continued in Step S4, the process returns to Step S2 again to perform “small inclination detection?”.

  In this way, when the amount of shake of the side brush exceeds a predetermined first shake, low-speed rotation control is performed to rotate the side brush at a low speed for a predetermined time. In addition, after performing low-speed rotation control for a predetermined time, the amount of side brush shake is confirmed again. At this time, if the amount is less than the predetermined amount, the rotation is returned to high speed, and if the amount is greater than the predetermined amount. Then, low-speed rotation control is performed again for a predetermined time.

  With the above-described car wash method, even if the pair of left and right side brushes suspended in a swingable manner is shaken, the shake can be quickly suppressed by reducing the rotational speed for a predetermined time. In addition, the deceleration time is a predetermined time, and even if deceleration control is performed, the brush continues to rotate, so that the reduction in cleaning power is minimized and the predetermined car wash effect is exhibited, and the car wash efficiency is not deteriorated. Possible car wash methods can be obtained.

  Also, a second shake detection sensor that detects a second shake larger than the first shake of the brush shaft is provided, and when the detection sensor detects the second shake, it determines that there is an abnormality and stops the rotation. Take control. With this configuration, when the side brush generates a second shake larger than the first shake, it is regarded as abnormal and stops rotating, so that it is possible to prevent damage to the vehicle to be cleaned and the car washer. This is preferable as a car washing method.

  As described above, the car wash method according to the present embodiment includes a side brush that cleans by rotating the brush shaft in the vertical direction, and performs the car wash while relatively moving the vehicle to be cleaned and the car wash machine body in the front-rear direction. A cleaning method for a machine, wherein the magnitude of brush shaft shake is detected, and when the detected shake is determined to be a first shake greater than or equal to a predetermined value, the rotational speed of the brush shaft is decreased for a predetermined time. This is a car wash method for performing control.

  That is, once the side brush is shaken while the side of the vehicle is being washed, this shake is immediately detected, and control is performed to rotate at a low speed for a predetermined time. Further, after a predetermined time has elapsed, the continuous determination control is performed, and it is determined whether the shake amount is detected again to continue the low speed rotation (continuous low speed rotation control) or return to the high speed rotation (rotational speed return control). Therefore, the car wash method according to the present embodiment is a car wash method that exhibits a predetermined car wash effect while minimizing a reduction in washing power, and can be washed without deteriorating the car wash efficiency.

  As described above, according to the car wash machine and the car wash method according to the present invention, when the side brush is swung freely while the side surface of the vehicle to be cleaned is washed with the side brush, Through the determination control, the first shake having a predetermined magnitude is detected and control is performed to reduce the rotational speed for a predetermined time (low-speed rotation control), so that the shake can be quickly suppressed. Further, since the rotation of the brush is continued, a car wash and a car wash method capable of performing a car wash without deteriorating the car wash efficiency without deteriorating the detergency and exhibiting a predetermined car wash effect.

  Also, once the side brush is shaken while washing the side of the vehicle, this shake is immediately detected and controlled to rotate at a low speed for a predetermined time. After the predetermined time has elapsed, the amount of shake is detected again (continuous determination control). The control of whether to continue low-speed rotation (continuous low-speed rotation control) or return to high-speed rotation (rotational speed return control) further suppresses the reduction in cleaning power and demonstrates the desired car wash effect Thus, the car wash machine and the car wash method do not deteriorate the car wash efficiency.

  Therefore, the car wash machine and the car wash method according to the present invention are preferably applied to a car wash machine for washing a vehicle side surface using a side brush suspended from the car wash machine body, and a car wash method using the car wash machine. The
