  The present invention relates to a car wash machine installed in a gas station, for example, and used for car washing, and more particularly to a car wash machine having two traveling bodies, a first traveling body that mainly performs cleaning and a second traveling body that mainly performs drying. .

  2. Description of the Related Art Conventionally, a car wash machine installed at a gas station, etc., sprays liquid or washing water stored in a liquid storage tank on the 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 washing while spraying a liquid agent and washing water, and drying by blowing air after washing are performed.

  Various shampoos, waxes and coats are used as the liquid agent used in car washing, and various liquid agents suitable for the type of vehicle to be cleaned and the surface coating layer have been proposed. These various liquid agents are respectively stored in dedicated liquid storage tanks, and are sprayed and consumed according to the process of the car washing process through a tube inserted in the tank. 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.

  In addition, when the vehicle to be cleaned is stopped at a predetermined washing position and the car wash machine is moved to perform car wash, the car wash machine main body is mainly composed of a first traveling body for cleaning and a second traveling body for mainly drying. When the cleaning is performed, the first traveling body including the cleaning means is moved to perform cleaning, and after the cleaning is completed, the second traveling body including the drying means such as the blowing nozzle is moved and dried.

Can be shortened.

JP 2003-160032 A

  By mounting the pulse encoder on the traveling motor and measuring the rotational speed of the motor, the traveling distance of each traveling body can be detected. However, if the traveling wheels run idle on the rails due to freezing or oil adhesion, the traveling body may not move even if the traveling motor rotates, and the motor speed matches the actual travel distance. Problems arise.

  Therefore, in order to accurately measure the travel distance of the traveling body, it is necessary to provide a measurement traveling wheel that rotates reliably without rotating on the rail, and to provide a pulse encoder that measures the number of rotations of the measurement traveling wheel. Is preferred.

  However, in order to prevent idling on the rail, there is a cost of newly installing a measurement traveling wheel including a biasing means for biasing the wheel against the rail and a pulse encoder. It is not preferable to attach the measurement traveling wheels to each of the traveling bodies because the cost is further increased.

  In the car wash machine described in Patent Document 1, when one of the traveling detection means (pulse encoders) attached to the first and second traveling bodies has a problem, the other normal traveling detection means It is disclosed to control the traveling of the traveling body on which the problem occurs using the detected value. However, control that executes new control when a problem occurs becomes complicated control, and is not preferable. As a configuration that always returns to the standby position normally with simpler control, stable running control is always performed. Is preferred.

  In view of the above problems, the present invention is a car wash machine having two traveling bodies, a first traveling body that mainly performs cleaning and a second traveling body that mainly performs drying. Another object of the present invention is to provide a car wash machine that always returns accurately from the car wash end point to the stand-by position, and that can accurately decelerate immediately before the stand-by position and stop normally at the stand-by position even when moving at high speed.

  In order to achieve the above object, the present invention relates a car wash machine main body having two traveling bodies, a first traveling body that mainly performs cleaning and a second traveling body that mainly performs drying, and a vehicle to be cleaned relative to each other in the front-rear direction. A car wash machine that performs a car wash while moving, wherein one of the first and second traveling bodies is provided with a measuring traveling wheel for accurately measuring a moving distance of the traveling body, A pulse encoder is attached to the traveling motor of the traveling body, and the traveling wheel for measurement of the one traveling body measures the pulse count value of the pulse encoder of the traveling body when the return movement of the other traveling body to the standby position is started. The correction is performed using the pulse count value.

  According to this configuration, even when the first traveling body and the second traveling body that have moved from the standby position at the time of the car wash return to the standby position after the car wash is completed, Since the motor pulse encoder count value is corrected to the accurately measured count value and moved, the car wash machine that can always decelerate right before the standby position and stop normally at the standby position even if it moves at high speed. Can be obtained. Moreover, since only the traveling wheel for measurement which requires cost is attached to one traveling body, it is advantageous in terms of cost.

  According to the present invention, in the car wash machine having the above-described configuration, the measurement traveling wheel urges the measurement wheel, the urging means to press the wheel against the rail, and a pulse encoder that measures a rotation pulse of the measurement wheel. It is characterized by having. According to this configuration, even if water or oil adheres to the rail or the rail freezes and becomes slippery, the measuring wheel is prevented from slipping via the biasing means, and the traveling body is accurately moved. It can be measured.

  According to the present invention, in the car wash machine having the above-described configuration, the measurement traveling wheel is mounted on the first traveling body, and a pulse encoder is mounted on the traveling motor of the second traveling body. According to this configuration, since the first traveling body that mainly performs cleaning is a long structure body that includes various cleaning nozzles and cleaning brushes, it is easy to arrange the traveling wheels for measurement, and mainly dry Since there is no need to provide a space for disposing the measurement traveling wheel in the relatively short second traveling body provided with the blowing nozzle for drying, the car wash having the traveling body for cleaning and the traveling body for drying is performed. The configuration is suitable for the machine.

  According to the present invention, in the car wash machine configured as described above, when the first traveling body is returned to the standby position, the first traveling body is moved based on the measured pulse count value of the measuring traveling wheel, After traveling, the vehicle is decelerated, and the first dog plate and the first limit switch, which are previously installed at predetermined positions, are engaged and stopped. According to this configuration, since it is based on the pulse count value of the measurement traveling wheel capable of accurate measurement, it is possible to quickly and stably return to the standby position.

  According to the present invention, in the car wash machine configured as described above, when the second traveling body is returned to the standby position, the second traveling body is moved based on the corrected pulse count value and decelerated after traveling at a predetermined count value at a high speed. Then, the second dog plate and the second limit switch, which are previously installed at predetermined positions, are engaged and stopped. According to this configuration, since the return movement of the second traveling body to the standby position is performed based on the pulse count value corrected to the correct count value, an error occurs in the movement detection distance after completion of the car washing process by the traveling motor. However, it is set to an accurate movement distance and can travel to a predetermined position at high speed.

  According to the present invention, in the car wash machine configured as described above, at least one of the first traveling body and the second traveling body is provided with a detecting unit that detects a separation distance between the both traveling units, and detection information of the detecting unit is provided. To control the traveling speed and stop control of the first and second traveling bodies, determine in advance the closest proximity distance and the most separated maximum separation distance, and determine the maximum separation distance as the first separation distance. Further, the second traveling body is characterized by a distance at which car washing can be performed at the same time without interfering with each car washing process. According to this configuration, both traveling bodies can be moved integrally at the same time, and the cleaning process by the first traveling body and the drying process by the second traveling body can be performed simultaneously. Furthermore, if the traveling bodies are too close to each other, this can be detected and the traveling speed can be reduced or stopped to prevent collision between the traveling bodies.

  Further, the present invention is characterized in that, in the car wash machine having the above-described configuration, a buffer member that relaxes contact between both traveling bodies is disposed on at least one of the first traveling body and the second traveling body. According to this configuration, even if an abnormality occurs in the traveling control of the traveling body, it is possible to mitigate the impact at the time of contact through the buffer member and suppress damage and failure.

  According to the present invention, a car wash is performed while relatively moving a car wash machine body and a vehicle to be cleaned having two traveling bodies, a first traveling body that mainly performs cleaning and a second traveling body that mainly performs drying, in the front-rear direction. In the car wash machine to be performed, one of the first traveling body and the second traveling body is provided with measuring traveling wheels for accurately measuring the moving distance of the traveling body, and the traveling motor of the other traveling body is provided. A pulse encoder is attached, and the pulse count value of the pulse encoder of the traveling body is measured by the traveling wheel for measurement of the traveling body at the start of the return movement of the other traveling body to the standby position. Since the correction is made, it is possible to move at a high speed when returning to the standby position by setting an accurate movement distance. In addition, since the distance to the standby position is always set accurately, the vehicle starts decelerating at a predetermined position immediately before the standby position, and can always stop accurately at the standby position. In addition, since only the traveling wheels for measurement that are costly are attached to one of the traveling bodies, a car wash machine that is advantageous in terms of cost can be obtained.

BRIEF DESCRIPTION OF THE DRAWINGS It is a schematic explanatory drawing which shows the car wash process of the car wash machine which concerns on this invention, Comprising: (a) shows the time of car wash mode setting, (b) shows the time of car wash start, (c) shows in the car wash process, d) shows the end of the car wash process, and (e) shows a state in which the car washer returns to the standby position and a new car wash is started.

  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.

  As shown in the overall configuration of FIG. 1 and the front view of FIG. 2, the car wash machine WA according to the present invention has two travels, a first traveling body 1A that mainly performs cleaning and a second traveling body 1B that mainly performs drying. A car wash machine main body 1 having a body is provided, and both the traveling bodies are gate-shaped so as to straddle the vehicle to be cleaned CA. In addition, both the traveling bodies are configured to travel along the rails 2 via the wheels 3, respectively, and the cleaning process and the drying are performed while relatively moving both the traveling bodies and the vehicle CA to be cleaned in the front-rear direction. Carry out the process and wash the car.

  In addition, an operation panel 7 and a remote panel 7A for setting a desired car wash mode are provided, and a pair of left and right rails 2 of the car wash machine WA that has a gate shape so as to straddle the vehicle to be cleaned CA, After stopping at a predetermined position between the two, the traveling body in the standby position is moved together and individually to perform a desired car wash.

  The first traveling body 1A that mainly performs cleaning 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. 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. In addition to these brushes, other brushes can be arranged at desired positions.

  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 section 50 provided in the car wash machine main body 1, and each nozzle is provided via a distribution pipe section 51 including an electromagnetic on-off valve and a sub-water supply hose. Is distributed. As a nozzle which sprays a liquid agent, the 1st water purification nozzle 11, the 1st detergent nozzle 12, the 2nd water purification nozzle 13, the water-repellent coating nozzle 14, etc. are arrange | positioned, for example. Furthermore, a second detergent nozzle 15 and a wax nozzle 16 can be provided. 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 sonic sensor using ultrasonic waves is preferably used.

  The second traveling body 1 </ b> B that mainly performs drying includes a blower 20, a vertically movable top blower nozzle 21 that blows air from the blower 20, and a pair of left and right side blower nozzles 22 as drying means.

  The first traveling body 1A and the second traveling body 1B are electrically connected to the operation panel 7 and the remote panel 7A, and can be individually and integrally driven and controlled according to a preset car wash mode. . For this purpose, the operation panel 7 and the remote panel 7A select various car washing modes such as a water washing mode, a washing mode using a detergent, a wax mode in which wax is applied, and a water repellent mode in which a water repellent is coated. A selection button, a brush rotation switch for controlling the number of rotations of the brush, a start / stop button, and the like are provided.

  Each traveling body moves from the standby position, which is the home position, and executes a car washing process consisting of a washing process and a drying process, and returns to the standby position after the car wash is completed. It is preferable to set the movement distance from the standby position accurately. In a general method of detecting a rotation pulse of a motor shaft by attaching a pulse encoder to a traveling motor, the slipping of a wheel, which is likely to occur at the start or stop of traveling, or in a state where the oil is attached or frozen. Due to idling, there may be an error between the motor speed and the actual travel distance.

  When a rotation pulse of the motor shaft is detected, if the wheel is idle, the traveling body does not advance even if the motor is rotating. Therefore, a rotation pulse more than the actually moved distance is measured. Therefore, if the rotation is returned by the amount of the rotation pulse measured at the time of the return movement to the standby position, it moves to a position beyond the standby position, resulting in inconvenience.

  Therefore, in this embodiment, it is set as the structure which provides the traveling wheel for a measurement for measuring the moving distance of this traveling body correctly in any one traveling body of said 1st and 2nd traveling body. In the other traveling body, a pulse encoder is attached to the traveling motor. This is because the measurement traveling wheel includes a dedicated wheel for measurement, a biasing means for biasing the wheel against the rail, and a pulse encoder for measuring the rotation pulse of the measurement wheel. This is because it is uneconomical to install the measuring traveling wheels on each traveling body. In addition, when the other traveling body starts to return to the standby position, the count value of the pulse encoder of the traveling body is corrected using the count value measured by the measurement traveling wheel of the one traveling body, thereby This is because even a traveling body that does not include the dedicated wheels can accurately return to the standby position while suppressing errors.

  In addition, when the urging force by the urging means is insufficient and slip occurs on the dedicated wheels included in the measurement traveling wheel 30, the pulse count value is less than the actual travel distance of the traveling body, resulting in a small count value. Therefore, it does not move to a position beyond the standby position. Therefore, even in this case, it is possible to travel at a high speed up to a predetermined count value.

  For example, as shown in FIG. 1, the measurement traveling wheel 30 is mounted on the first traveling body 1 </ b> A, and the pulse encoder (not shown) is mounted on the traveling motor of the second traveling body 1 </ b> B. This is because the first traveling body 1A that mainly performs cleaning is provided with various liquid agent nozzles such as each cleaning nozzle and wax nozzle and a cleaning brush, so that the first traveling body 1A has a long structure. This is because it is possible to easily secure a space for disposing of. In addition, since the measurement traveling wheel is not disposed on the second traveling body 1B, the second traveling body 1B having various drying blowing nozzles is easy to configure and preferable.

  As described above, if the measurement traveling wheel 30 is provided as the travel distance detecting means, the travel distance of the traveling body from the standby position is accurately measured via the pulse encoder provided on the measurement traveling wheel 30. It is possible to obtain information on the length direction of the vehicle body from the measured traveling distance of the traveling body. Furthermore, it is easy to return to a predetermined standby position by moving it backward by the travel distance of the traveling body measured via the pulse encoder. For this reason, it is possible to perform a control of moving at a high speed immediately before the standby position and then decelerating and stopping, thereby shortening the car wash cycle and improving the operation efficiency of the car wash machine.

  Each traveling body can be stopped at a predetermined standby position by engaging the limit switch 10 and the dog plate 9. For example, the first dog plate 9A installed on the ground side of the standby position engages with the first limit switch 10A provided on the first traveling body 1A side, and the first traveling body 1A stops at a predetermined position, and the second dog It can be set as the structure which the plate 9B and the 2nd limit switch 10B provided in the 2nd traveling body 1B side engage, and the 2nd traveling body 1B stops in a predetermined position. At this time, the limit switch 10 may be installed at each standby position, and the dog plate 9 may be disposed on the traveling body side, and either the limit switch 10 or the dog plate 9 is disposed on the stop portion side and the moving body side, respectively. Any configuration may be used.

  In the case of the traveling body configured as described above, since the distance moved from the standby position is accurately measured, when returning to the standby position, the distance is moved to just before the standby position, and then the limit switch 10 and the dog plate 9 are It can be controlled to move at low speed until it is engaged. As described above, since the moving distance is accurately measured based on the pulse count value of the measurement traveling wheel, it is possible to quickly and stably return to the standby position.

  Further, by providing a defining means for defining the separation distance between the first traveling body 1A and the second traveling body 1B, and predetermining the closest approach distance and the most separated maximum separation distance, a predetermined distance is provided. It is preferable that both the traveling bodies are driven integrally to continuously execute the cleaning process and the drying process, or can be integrally returned to the standby position. The defining means may include a stopper member that defines the proximity distance and a wire member that couples both traveling bodies and defines the maximum separation distance. Alternatively, a first photoelectric sensor that detects when both traveling bodies are close to each other and a second photoelectric sensor that is not detected when both traveling bodies are separated from each other by a predetermined distance, and controls the driving of both traveling bodies by the detection signals of these detection means. Configuration defining means can also be used. For example, the proximity distance and the maximum separation distance can be defined by providing the detection means on at least one of the traveling bodies and controlling the driving of both traveling bodies by the detection signal of the detection means.

  If the detection means for detecting the separation distance between the first traveling body 1A and the second traveling body 1B is provided, the separation distance between the first and second traveling bodies is determined by the first and second traveling bodies, respectively. It is possible to set the distance at which car washing can be performed at the same time without hindering the car washing process. If both the traveling bodies can be operated at the same time, it is possible to simultaneously move both traveling bodies together so that the washing process by the first traveling body and the drying process by the second traveling body can be performed at the same time. It can be shortened. Furthermore, if the traveling bodies are too close to each other, this can be detected and the traveling speed can be reduced or stopped to prevent collision between the traveling bodies.

  In addition, it is preferable that a buffer member (for example, a rubber material: not shown) that relaxes the contact between both the traveling bodies is disposed on at least one of the first traveling body 1A and the second traveling body 1B. With this configuration, even if an abnormality occurs in the traveling control of the traveling body, it is possible to mitigate the impact at the time of contact via the buffer member and suppress damage and failure.

  Next, an embodiment of the traveling wheel for measurement will be described with reference to FIG.

  3A, the box main body 31 is supported by a bearing 32 so as to be swingable via a support shaft 33, and the wheel 34, which is a driven wheel, is urged in a direction in which the wheel 34 is pressed against the rail 2. A spring member 38 is provided. Therefore, the wheel 34 does not slip and rolls on the rail 2 and can be used as a measuring wheel.

  A wheel 34 and a pulse count disk 37A are rotatably supported on the box body 31 and are connected by a transmission 35 such as a belt or a chain. The pulse count disk 37A is a disk having a large number of slits and notches on the circumference, and a pulse count sensor 37B for detecting these slits and notches to detect a rotation pulse of the disk. In addition, a pulse encoder 36 is configured.

  The pulse count sensor 37B is a sensor that detects a slit or notch of the rotating pulse count disk 37A and counts a pulse value synchronized with the rotation, and a magnetic or optical sensor can be used. In addition, a plurality of sensors can be provided at a plurality of positions in the slits and notches to enable high-resolution pulse counting, and a more accurate pulse signal can be obtained.

  The obtained pulse signal is synchronized with the rotation of the wheel 34. Further, the wheel 34 is urged by the spring member 38 and pressed against the rail 2 to rotate according to the movement of the traveling body without slipping or idling. Therefore, the movement of the traveling body can be accurately known from the pulse value counted by the measurement traveling wheel 30.

  The wheel 34 used as the measurement wheel may be a wheel that rolls without slipping on the rail 2, and may be made of metal or resin, and is not particularly limited. Moreover, the shape is not particularly limited, either when a mountain-shaped rail is used, a grooved shape that engages with this mountain shape, or a cylindrical shape that rolls on the top surface of the mountain-shaped tip.

  Moreover, a pulse encoder can also be provided in the motor for driving which drives the wheel 3 like the 2nd traveling body 1B mentioned above. An example of this pulse encoder is shown in FIG. The pulse encoder 40 shown in FIG. 3B has a pulse count disk 42 attached to the tip of the motor shaft 41 of the traveling motor M, and a pulse for detecting a slit or notch formed in the pulse count disk 42. The count sensor 43 is provided.

  With this configuration, since the pulse value corresponding to the rotation of the traveling motor M is detected, the rotation pulse of the wheel 3 that rotates in synchronization with the traveling motor M is detected. However, as described above, when slipping or idling occurs in the wheel 3, even when the traveling motor M rotates, the traveling body may not move, and the detected pulse value is between the actual traveling distance. An error occurs.

  In this embodiment, the measurement traveling wheel 30 having the pulse encoder 36 is mounted on the first traveling body 1A, the pulse encoder 40 is mounted on the traveling motor M of the second traveling body 1B, and the detected pulse value When the second traveling body 1B, which may cause an error with respect to the actual traveling distance, returns to the standby position, the count value of the pulse encoder of the traveling motor M is set to the measuring traveling wheel 30 of the first traveling body 1A. It was set as the structure corrected using the count value which measured.

  Therefore, when the first and second traveling bodies are moved and the vehicle is washed to return to the standby position, the count value of the second traveling body is corrected to the correct count value and then moved to the correct return distance. be able to. Therefore, it is possible to move to a predetermined count value immediately before the standby position at a high speed and then decelerate and stop.

  With the configuration described above, even if the vehicle moves at a high speed, it can be accurately decelerated immediately before the standby position and can always stop normally at the standby position, and can quickly and stably return to the standby position. . In addition, the car wash cycle can be shortened and the operating efficiency of the car wash machine can be improved.

  Next, the car washing process will be further described with reference to FIG.

  As shown in FIG. 4A, first, the vehicle to be cleaned CA1 enters the remote panel 7A and stops. Then, the user (driver) sets his / her desired car wash mode and car wash course on the remote panel 7A and presses the start button.

  Then, the circuit breaker 61 goes up and can enter the car wash position. As shown in FIG. 4B, the user operates the start button on the operation panel 7 after detecting that the vehicle CA1 to be cleaned has stopped at the car wash position or after stopping the vehicle CA1 to be cleaned at the car wash position. After that, the first traveling body 1A starts moving forward.

  When the first traveling body 1A starts moving forward, the distance from the second traveling body 1B that is separated by a predetermined proximity distance L1 + α is increased at the standby position. The first traveling body 1A and the second traveling body 1B can be individually moved and washed to perform car washing, but both traveling bodies can be moved together to perform car washing at the same time. At this time, the second traveling body 1B is traveled and moved so that the distance between both traveling bodies is a predetermined maximum separation distance L2. Further, as described above, the maximum separation distance L2 is set to a distance at which the first and second traveling bodies can simultaneously perform car washing without hindering the respective car washing processes.

  When the first traveling body 1A reaches the predetermined cleaning start position, as shown in FIG. 4 (c), the cleaning process by the first traveling body 1A is executed, and the drying by the second traveling body 1B separated by a predetermined distance is performed. The process is executed continuously. When the car wash process including the washing process and the drying process is completed, the first traveling body 1A is stopped at a predetermined car wash end position, and then the second travel body 1B is stopped at a car wash end position separated by a predetermined proximity distance L1.

  In this way, the first traveling body 1A and the second traveling body 1B are simultaneously moved away from each other by a predetermined distance, and the washing process and the drying process are simultaneously performed, so that the washing is performed immediately after the washing, and the car washing time is reduced. By shortening, the car wash efficiency can be improved.

  Further, during the washing of the vehicle to be cleaned CA1, a new vehicle to be cleaned CA2 enters the remote panel 7A, and the next car wash condition can be selected.

  When the car wash of the vehicle to be cleaned CA1 is completed and the first traveling body 1A and the second traveling body 1B are stopped at a predetermined stop position (car wash end position), a front indicator light (not shown) leaves the vehicle to be cleaned CA1. 4 (d), the driver leaves the vehicle to be cleaned CA1 and exits from the front exit.

  Then, as shown in FIG. 4E, after the vehicle to be cleaned CA1 leaves, the second traveling body 1B and the first traveling body 1A are moved to the original standby position. Also during this return movement, the separation distance between the first traveling body 1A and the second traveling body 1B may be the proximity distance L1, but is preferably set to the maximum separation distance L2 that is slightly separated.

  When the first traveling body 1A and the second traveling body 1B are moved back and returned at the same time, the second traveling body 1B reaches the predetermined position and decelerates because the second traveling body 1B is at the head. Is started, it is preferable that the first traveling body 1A is also decelerated while considering the occurrence of slip of the second traveling body 1B. Further, when the first traveling body 1A and the second traveling body 1B return to the standby position, the circuit breaker 61 is raised so that a new vehicle to be cleaned CA2 can enter the washing position.

  In order to shorten the car wash cycle, it is important to perform the return movement of the first traveling body 1A and the second traveling body 1B in a short time. In addition, it is difficult to provide the measurement running wheel 30 with a relatively short size, and a blower and a nozzle member for drying are provided in the upper part of the machine base so that the center of gravity is relatively high, and slipping or It is important to move the second traveling body 1B, which is likely to be idling, as fast as possible and stop it at an accurate position.

  Therefore, when the second traveling body 1B returns to the standby position, the count value of the pulse encoder of the traveling motor M is corrected using the count value measured by the measuring traveling wheels 30 of the first traveling body 1A. According to this embodiment, the return movement distance can be set to an accurate distance, and high-speed movement to a predetermined position is possible. Further, since the distance to the standby position is set accurately, the vehicle can start decelerating immediately before the standby position, and can normally stop at a predetermined standby position. In this way, it is possible to quickly and stably return to the standby position.

  As described above, according to the car wash machine according to the present invention, the car wash machine main body and the vehicle to be cleaned having two running bodies, which are the first traveling body that mainly performs cleaning and the second traveling body that mainly performs drying, are moved forward and backward. In a car wash machine for washing the vehicle to be cleaned while moving relative to each other in a direction, for measurement to accurately measure the travel distance of the traveling body on one of the first and second traveling bodies A traveling wheel is provided, a pulse encoder is attached to the traveling motor of the other traveling body, and the count value of the pulse encoder of the traveling body is set to the one of the traveling body at the start of return movement to the standby position of the other traveling body. Since the correction is made by using the count value measured by the measurement traveling wheel, it is possible to set an accurate movement distance and move at a high speed when returning to the standby position. In addition, since the distance to the standby position is accurately set, the vehicle can decelerate at a predetermined position immediately before the standby position, and can always stop normally at the standby position. In addition, since only the traveling wheels for measurement that are costly are attached to one of the traveling bodies, a car wash machine that is advantageous in terms of cost can be obtained.

  Further, since the car wash cycle can be shortened and the operation efficiency of the car wash machine can be improved, the car wash machine according to the present invention is more convenient for the manager who installs the car wash machine and the user (driver) who uses it. It becomes a good car wash machine.

  Therefore, the car wash machine according to the present invention is suitably applied as a car wash machine in a car wash place used by a plurality of users.
