Description

  The present invention relates to a self-service car wash apparatus that receives a car wash service by a car wash machine body after the car wash user enters the car wash area in the car wash area of the car wash machine body and stops at a predetermined stop position. Is.

  This type of car wash device has a portal-type car wash machine body that travels across a car parked at a predetermined stop position. When using this car wash device, the car wash user puts the car in the car wash area, stops the car at the stop position, receives the car wash while on the car, and when the car wash is finished Used for self-service to leave the car out of the area.

  In such a car wash apparatus, since a car wash user receives a car wash service while riding on a car, a car wash accident caused by moving (self-propelled) the car during car wash has been reported. Therefore, as shown in Patent Document 1, a stop plate with a depression switch for detecting that a tire (front wheel) has entered the stop position is provided, and self-running during the car wash is detected to abnormally stop the car wash.

  As a cause of self-running during car washing, for example, a case where the car is advanced from the illusion that the car must be brought close to the approaching car wash brush (1), a case where the car is moved backward from the fear of the approaching car wash brush (2), drying There is a case (3) or the like in which the vehicle is moved forward when the nozzle reaches the rear of the vehicle and the vehicle is misunderstood. The tire stop plate of Patent Document 1 can detect the movement of the automobile by turning the depression switch from ON to OFF, but cannot determine whether the automobile has moved forward or backward. The car wash is stopped abnormally when self-running occurs and the depression switch turns from ON to OFF.

  When a car wash stops abnormally, the car wash manager must take error-handling measures by manual operation while checking the state of the car and brush. Of the cases (1) to (3), the case (1) has a high risk of causing the automobile to collide with the approaching car wash brush. Since there is a relatively low risk of a car hitting a car wash brush or a drying nozzle, error-relief measures are often unnecessary. Nevertheless, since it is necessary to check the state of the car wash every time an abnormal stop occurs, a considerable burden is placed on the car wash administrator, and the operation efficiency of the car wash machine is reduced.

Japanese Patent No. 2876933

  Therefore, the present invention provides a car wash device that reduces the burden on the car wash manager and prevents the operation rate of the car wash machine from being lowered, without causing unnecessary abnormal stops even if self-running occurs during the car wash. Objective.

  In order to solve such a problem, the present invention provides a car wash processing apparatus installed in a car wash machine body by running a car wash machine body formed in a gate shape with respect to an automobile stopped at a stop position in a car wash area.

When the first and second switches of the means turn to tire non-detection, the movement and movement direction of the automobile are detected from the order, and the abnormal stop is made according to the movement direction of the automobile and the car wash situation of the car wash machine body. Determine whether, with the car wash control means for providing a corrective action in the abnormal stopping is judged to be unnecessary car wash body and car wash processing apparatus.

  The tire detection means detects that the vehicle has moved forward from the stop position when the second switch turns to tire non-detection after the first switch turns to tire non-detection, and the second switch turns to tire non-detection. After that, when the first switch turns to tire non-detection, it is detected that the automobile has moved backward from the stop position.

  When the car wash control means detects that the car has moved in the direction opposite to the direction of movement of the car wash machine at the stage where the car wash treatment device acts on the upper surface of the car body while the car wash machine moves, an abnormal stop is unnecessary. It judges and returns a car-washing machine main body and a car-washing processing apparatus to a car-wash start position as coping action, and performs the alert | report which guides to a stop position with respect to a motor vehicle.

  In addition, when the car wash control means detects that the car has moved in the direction opposite to the direction of movement of the car wash machine body at the stage after the car wash processing apparatus reaches the highest position of the car while the car wash machine body moves, It is determined that an abnormal stop is unnecessary, and the movement of the main body of the car wash machine is continued in a state where the lowering of the car wash processor is prohibited as a coping operation.

  ADVANTAGE OF THE INVENTION According to this invention, even if self-propelled driving | running | working occurs during a car wash, without making an unnecessary abnormal stop, the burden of a car wash administrator can be reduced and the operating rate of a car wash machine can be prevented from decreasing.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a plan view showing a car wash apparatus according to an embodiment.
Reference numeral 1 denotes a car wash machine body, which is formed in a gate shape and reciprocates on rails 2 and 2 to provide a car wash processing apparatus in the car wash machine body 1 for entering a car wash area A formed between the rails 2 and 2. Wash and dry with Near the entrance of the car wash area A are provided a car wash acceptance device 3 for accepting a car wash such as selecting a desired car wash course by introducing a car wash fee, and a gate device 4 for restricting entrance to the car wash area A, When the car wash acceptance device 3 is operated while being on the car and the car wash is accepted, the gate of the gate device 4 is opened and the car can enter the car wash area A.

  Reference numeral 5 denotes a tire detection device which detects a vehicle tire and gives a stop position of the vehicle in the car wash area A. The tire detection device 5 is laid on the floor surface of the car wash area A, which is a predetermined distance ahead of the car wash machine body 1 at the standby position, and is arranged so as to sandwich the car to be washed in the vehicle width direction as shown in FIG. A pair of left and right sensor units 6 and 7 and a tire stopper 8 provided across the sensor units 6 and 7 on the back side in the approach direction of the sensor units 6 and 7 are configured.

  The sensor unit 6 has two light emitting portions 6a and 6b arranged in the front and rear of the direction of entry of the automobile, and is protected by a cover 6c. The sensor unit 7 includes light receiving portions 7a and 7b facing the light emitting portions 6a and 6b of the sensor unit 6, and is protected by a cover 7c. The sensor units 6 and 7 form the optical axis B1 of the light emitting part 6a-light receiving part 7a in the front with respect to the direction of entry of the automobile, and the light axis B2 of the light emitting part 6b-light receiving part 7b is formed in the rear. The stop of the automobile is detected based on the detection status of the optical axis.

  The tire detection device 5 functions as a stop detection that gives a stop position of the car when the car enters the car wash area A, and monitors that the car is at the stop position after the car wash is started. It functions as self-running detection. For this reason, the distance S between the optical axes B1 and B2 corresponds to the contact length for each tire size, and is determined in consideration of detection accuracy in each function of the stop detection function and the self-running detection function.

  For example, in the stop detection function, as shown in FIG. 3 (a), the range where both the optical axes B1 and B2 are shielded by the tires is set to an appropriate stop position of the vehicle, so that any size tire can be reliably used. The distance S between the optical axes B1 and B2 is determined in consideration of the stop allowable range R1 that affects the detection accuracy on the condition that the light shielding state of both optical axes is obtained.

  Further, in the self-running detection function, as shown in FIG. 3B, since the state where both the optical axes B1 and B2 are changed from light shielding to light transmission is the movement of the automobile, the light axis B1 light shielding-optical axis. The distance S between the optical axes B1 and B2 is determined in consideration of the free-running allowable range R2 from the state of B2 light transmission to the light transmission from the optical axis B1 to the light shielding of the optical axis B2. Here, S = 50 to 100 mm is set in consideration of these conditions.

  9 is a guide indicator, which is installed behind the exit of the car wash area A. When the car wash is accepted, it will guide the entrance of the car. During the car wash, it will display the progress of the car wash operation and the occurrence of abnormalities. Guide you to leave. In the entrance guidance, instructions such as “forward”, “stop”, and “reverse” are displayed on the vehicle entering the car wash area A in accordance with the state of the vehicle provided by the tire detection device 5. The car wash guidance displays a car wash process that is being executed and a caution notice that prohibits self-running. In the leaving guidance, the car washing is completed and an instruction to move the car is displayed. It should be noted that the position may be a position that is easily visible from the driver's seat when entering the car and during the car wash, and may be of a swinging type that is retracted from the car exit path when leaving the car.

  The car wash processing apparatus equipped in the car wash machine body 1 is provided with washing brushes 10, 11, 11, drying nozzles 12, 13, 13, watering nozzles (not shown), and the like.

The cleaning brush includes a top brush 10 that moves up and down along the upper surface of the vehicle body and brushes the upper surface, and a pair of left and right side brushes 11 that move toward and away from the vehicle body in the width direction and brush the front and rear surfaces and side surfaces of the vehicle body. -It consists of 11. The drying nozzle is composed of a top nozzle 12 that moves up and down along the upper surface of the vehicle body and blows high-pressure air onto the upper surface, and a pair of left and right side nozzles 13 and 13 that blows high-pressure air onto the side surface of the vehicle body.

  As other equipment, a travel detection device 14 that detects the travel position of the car wash machine main body 1 and a vehicle shape detection device 15 that detects the upper surface position of the automobile are provided. The travel detection device 14 includes a travel motor that drives the wheels of the car wash machine main body 1 and a travel encoder that is linked to the output shaft of the travel motor. Each time the car wash machine main body 1 travels a unit distance by driving the travel motor. The traveling position of the car wash machine main body 1 is detected by counting the pulse signals output from the traveling encoder. The vehicle shape detection device 15 is provided at a front position of the car wash machine body 1 and includes a light emitting unit in which a plurality of light emitting elements are arranged vertically, and a light receiving unit in which a plurality of light receiving elements are arranged vertically corresponding thereto. A car wash machine that is opposed to each other and that receives a pulse signal from a travel encoder as a trigger to transmit and receive an optical signal (infrared light) between them to detect the upper surface position of the vehicle body to be washed and to be obtained by the travel detection device 14 The top contour of the vehicle body is extracted together with the travel position of the main body 1, and the car parts are detected from the extracted top surface contour, such as bonnet, window, roof, trunk, car type, car position, and the position and type of protrusions. Create control data for the processor.

  Further, the car wash machine main body 1 has an entrance sensor 16 for detecting the entrance of an automobile at the front part, an exit sensor 17 for detecting the exit of the automobile at the rear part, and an area sensor 18 for detecting an object on the rear side. I have. The entrance sensor 16 and the exit sensor 17 form an optical axis by making the light emitting portion and the light receiving portion face each other in the vehicle width direction, and detect the presence or absence of the vehicle body by transmitting / shading the optical axis. The sensor 16 is attached in a state of protruding forward from the front surface of the main body 1 by an attachment arm, detects the front end position of the automobile together with the vehicle shape detection device 15, and stops the vehicle when the tire detection device 5 cannot be used. Output the position. The area sensor 18 detects the presence or absence of an object by detecting the reflected wave of the irradiated infrared light. When the main body 1 moves backward, the area sensor 18 outputs the presence of a car, a person, or the like that is moving in the traveling direction.

  The car wash apparatus configured as described above receives a car wash by the car wash accepting apparatus 3 and causes the car to enter the car wash area A along the guidance of the guide indicator 9 from the opened gate apparatus 4. After the car is stopped at the stop position given by the vehicle and a car wash service is received by the car wash machine main body 1, the vehicle is operated in a drive-through manner in which it exits to the rear of the car wash machine main body 1. The self-service car washing device is not limited to the drive-through method, and there is a method in which the car is retracted and exited after washing the car, and the car is moved backward from the front of the car washing machine by retracting the main body of the car after washing. There is also a method.

FIG. 4 is a block diagram showing a control system of the car wash apparatus.
Reference numeral 20 denotes a car wash control board built into the car wash machine main body 1, 21 denotes a reception control board built into the car wash acceptance device 3, both of which are equipped with a microcomputer, and both boards are connected by a serial transmission cable 22. ing.

  The car wash control board 20 is connected to the travel detection device 14, the vehicle shape detection device 15, the vehicle entry sensor 16, the vehicle exit sensor 17, and the area sensor 18, and through the car wash drive unit 23, 11 and drying systems 12 and 13) are connected, and the operation of each connected element is controlled based on a car wash request signal transmitted from the reception control board 21 via the transmission cable 22.

  The reception control board 21 is connected to the gate device 4, the tire stop device 5, the guide indicator 9, and the reception operation panel 24, and can receive a car wash fee and menu selection from the reception operation panel 24. A car wash request signal is output to the car wash control board 20. The reception operation panel 24 is a voice reception section for accepting a car wash fee with cash or a prepaid card, a key input section such as a car wash menu key, a car wash start key, a cancel key, and operation guidance and entrance guidance to a car wash space. And a voice guide unit to be provided.

Next, the operation of the car wash apparatus of the present invention configured as described above will be described.
When the vehicle enters the car wash acceptance device 3 and the driver starts the car wash acceptance with the car wash acceptance device 3 while in the car, the reception control board 21 checks the optical axis of the tire stop device 5 and each optical axis B1.・ Check if B2 operates normally. In the optical axis check, the difference level between the light reception level at the light receiving units 7a and 7b before the light emitting units 6a and 6b emit light and the light reception level at the light receiving units 7a and 7b after the light emitting units 6a and 6b emit light. Is higher than the reference value, it is determined that each of the optical axes B1 and B2 is normal (that is, there is no light emission failure or light reception failure), and vehicle entry guidance based on the tire stopping device 5 is performed.

  If an abnormality in the optical axes B1 and B2 is recognized in the optical axis check, stop guidance based on the tire stop device 5 is not performed, and stop guidance is performed by the vehicle shape detection device 15 and the vehicle entrance sensor 16. As for the stop guidance by the vehicle shape detection device 15 and the vehicle entry sensor 16, the vehicle shape detection device 15 located in the car wash machine body 1 is detected by the vehicle detection sensor 16 located on the front side of the car wash machine body 1. Since this is the same as the conventional method in which the stop position of the automobile is set at a position where the vehicle body is not detected, description thereof will be omitted.

Subsequently, vehicle entry guidance when the vehicle enters the car wash area A will be described with reference to FIG.
When the car wash acceptance is completed and the gate device 4 is opened, the guide indicator 9 displays "forward" guidance in a state where both optical axes B1 and B2 of the tire detection device 5 are transparent (a), and the tire The light transmitting / shading state of the stopping device 5 is monitored. The user enters the car into the car wash area A according to the guide display, and enters the tire stop 8 of the tire stop device 5 as a guide.

  As the vehicle enters, the tire (front wheel) blocks the optical axis B1 (b), and then the optical axis B2 also blocks both the optical axes (c), so that the vehicle reaches the stop position. The guidance display 9 displays a “stop” guidance display and prompts the user to stop. The user only has to stop the driving of the automobile according to this guidance. When the state where the vehicle is stopped at the stop position continues for a predetermined time or more, the stop is confirmed and the car washing operation is started.

  When the tire (front wheel) passes through the stop position and the optical axis B1 changes from light blocking to translucent (d), it is determined that the automobile has gone too far from the stop position, and the guide display 9 displays a "reverse" guidance display. Encourage backwards. The user can stop the vehicle at a predetermined stop position by backing the vehicle according to this guidance.

  When the user continues to move the vehicle forward even though the “reverse” guidance display is displayed on the guide display 9, and both optical axes B1 and B2 turn to translucent light (e), the tire (front wheel) becomes the tire. It is determined that the detection device 5 has been penetrated, and the guidance display is switched according to the light axis that is shielded next. That is, it is determined whether the tire detected by the tire detection device 5 is the front wheel or the rear wheel from the order in which the optical axis B1 and the optical axis B2 change from light transmission to light shielding.

  Here, when the optical axis B2 is shielded first (d), it is determined that the tire detection device 5 has detected the front wheel of the automobile by the backward movement of the automobile, and the guidance display 9 continues the "reverse" guidance display. Subsequently, when the optical axis B1 is also shielded and both the optical axes are shielded, it is determined that the automobile has reached the stop position, and the guidance display 9 displays a “stop” guidance display.

  On the other hand, when the optical axis B1 is shielded first (f), the vehicle continues to move forward and it is determined that the tire detection device 5 has detected the rear wheel of the vehicle, and the guidance display 9 continues to display “reverse” guidance. Subsequently, when the optical axis B2 is also shielded and both optical axes are shielded (g), the guide display 9 displays a "warning" guidance. In addition, since it is an obvious abnormal state that the tire detection device 5 detects the rear wheel of the vehicle, it is desirable to issue a warning to return to the correct position by outputting sound in addition to the guide display.

  When the stop position is determined by the above procedure, the car wash machine main body 1 travels (first travel), along the vehicle shape detected while detecting the shape of the automobile with the travel detection device 14 and the vehicle shape detection device 15. A cleaning process for causing the cleaning brushes 10, 11, and 11 to act on the vehicle body surface is executed. Subsequently, the car wash machine main body 1 is returned (first return), and similarly, a cleaning process is performed in which the cleaning brushes 10, 11, 11 are applied to the vehicle body surface. Finally, the car wash machine body 1 is made to travel again (second travel), and a drying process is performed in which the drying nozzles 12, 13, and 13 act on the body surface along the vehicle shape. The car wash ends with stopping at the entrance side of area A. When the car wash is completed, the vehicle is guided by the guide display 9 and the vehicle is exited in accordance with the exit guide. When the tire detection device 5 and the car exit sensor 17 confirm the car exit, the car wash machine body 1 is returned to the standby position. End. The car washing course can be executed other than the 1.5 round-trip car washing of the car washing machine main body 1 as described above.

  During the car wash thus performed, the tire detection device 5 monitors the movement (self-propelled) of the automobile. Here, if the movement (self-propelled) of a car is detected during the car wash, there is a concern that the car may come into contact with the washing brush or the drying nozzle and break, and the detected car shape will be misaligned. The machine body 1 is stopped urgently to stop the car wash. However, if the moving direction of the car moves away from the washing brush or the drying nozzle, the risk of a contact accident is reduced. Therefore, the car washing is temporarily stopped and the car washing machine main body 1 is returned to the car washing start position to perform the washing again. In some cases, the car wash can be continued by limiting the operation of the car wash brush and the drying nozzle. Therefore, in the present invention, the car wash manager manually cancels the error by determining the car wash stop / car wash continuation / car wash interruption according to the moving direction of the car and the car wash situation, and reducing the chance of abnormal stop during the car wash. The effort is reduced.

  The moving direction of the automobile is determined based on which optical axis B1 or B2 is first converted to light transmission when both optical axes B1 and B2 of the tire detection device 5 are changed from light shielding to light transmission. That is, self-running is detected when both optical axes B1 and B2 change to translucent from the stop state where both optical axes B1 and B2 of the tire detection device 5 are shielded from light, and the optical axis B1 changes to translucency. When the optical axis B2 changes to translucency, it is determined that the automobile has moved forward. When the optical axis B2 changes to translucency after the optical axis B2 has changed to translucency, the automobile has moved backward. to decide.

  Next, when the moving direction of the automobile is detected, as shown in FIG. 6, the car washing process being performed and the position of the washing brush and the drying nozzle based on the traveling position of the car wash machine body 1 are determined according to the relative position of the automobile. Deal with the move.

  When the top brush 10 is in the range (i) from the standby position to the car body surface of the automobile in the first outbound (washing process) of the car wash machine body 1, the tire detection device 5 detects the backward movement of the automobile. In this case, since the risk of the top brush 10 and the automobile coming into contact with each other is low, the car washing operation is temporarily stopped by stopping the running of the car wash machine body 1 and the raising and lowering and rotation of the top brush 10. After the “Movement prohibited” warning is displayed, the “Move forward” guidance is displayed. Here, when the stop position is confirmed again by the tire detection device 5, the car wash main body 1 and the top brush 10 can be returned to the standby position to restart the car wash.

  Further, when the top nozzle 12 is in a range (i) from the standby position to the vehicle body surface of the vehicle in the second outbound (drying process) of the car wash machine body 1, the tire detection device 5 moves the vehicle backward. Since the risk of contact between the top nozzle 12 and the automobile is low, the vehicle washing machine body 1 is temporarily stopped and the top nozzle 12 is raised and lowered to interrupt the washing operation. After the “Movement prohibited” warning is displayed, the “Move forward” guidance is displayed. Here, when the stop position is confirmed again by the tire detection device 5, the car wash machine body 1 and the top nozzle 12 can be returned to the standby position to restart the car wash.

  Furthermore, when the top nozzle 12 is in the range (c) after exceeding the highest position of the vehicle in the second outbound (drying process) of the car wash machine body 1, the tire detector 5 detects the forward movement of the vehicle. Then, since the possibility that the automobile and the drying nozzle come into contact with each other is low, the car wash can be continued by prohibiting the top nozzle 12 from being lowered without causing an abnormal stop.

  In addition, as a cause that the car moves during the car wash, there are a case where the driver runs the car himself and a case where the car moves due to the impact when the car wash brush is pressed against the car. Since both optical axes B1 and B2 of the tire detection device 5 are hardly switched to light shielding, self-running can be determined in the situation of both optical axes B1 and B2.

  The present invention can be implemented as described above, but is not limited to the above embodiments. In the embodiment, the drive-through type car wash apparatus has been described, but the present invention can be applied to other self-service car wash apparatuses. Moreover, although the reflection type and the transmission type photoelectric switch are used as the vehicle body detection device, any device can be applied as long as it can detect the presence of the vehicle body in a predetermined area without being limited to the photoelectric switch.
