The self-traveling state detection means continuously detects travel positions of a body frame, using a travel encoder during moving forward time of the body frame from a start point SP where a first vehicle sensor 10 detects a vehicle body while a vehicle shape sensor 9 and a second vehicle sensor 11 do not detect the vehicle body; and determines that the car is in a self-traveling state when a distance a between a travel position P1 where the vehicle shape sensor 9 detects the vehicle body, and a travel position P2 where the second vehicle body sensor 11 detects the vehicle body, is different from a distance A between installed positions of the vehicle shape sensor 9 and the second vehicle sensor 11; and also determines that the car is in the self-traveling state when a distance b between a travel position P3 where the first vehicle sensor 10 comes to detect no vehicle body, and a travel position P4 where the vehicle shape sensor 9 comes to no longer detect the vehicle body, is different from a distance B between installed positions of the first vehicle body sensor 10 and the vehicle shape sensor 9.SELECTED DRAWING: Figure 4

Description

  The present invention relates to a drive-through type car wash apparatus that receives a car wash service as a main body frame reciprocates after entering a car wash space after receiving a car wash and stopping at a predetermined stop position. This relates to a function for detecting the occurrence of a failure.

  Since the drive-through type car wash device receives a car wash service while the driver is in the car, a self-propelled accident that accidentally moves the car during the car wash and damages the car or the car wash machine has occurred. In response to this problem, in Patent Document 1, as shown in FIG. 7, a first vehicle body detection BS1 and a second vehicle body detection BS2 are provided at at least two positions along the front-rear direction of the car wash machine body. The movement distance A of the car washing machine body while BS1 detects the front end and the rear end of the vehicle body and the movement distance B of the car wash machine body while the second vehicle body detection BS2 detects the front edge and the rear end of the vehicle body are constant. There has been proposed a car wash machine that determines that a vehicle has moved if a difference occurs.

  Further, the document 1 describes the movement distance C1 of the car wash machine body from when the first vehicle body detection BS1 detects the front end of the vehicle body until the second vehicle body detection BS2 detects the front end of the vehicle body, and the first vehicle body detection BS1. The movement distance C2 of the car wash machine body from when the rear end of the vehicle body is detected to when the second vehicle body detection BS2 detects the rear end of the vehicle has a certain difference from the installation interval D of each of the vehicle body detection BS1 and BS2. It is disclosed that it is determined that the vehicle has moved when it occurs, and further that the first vehicle body detection BS1 is also used as a vehicle shape sensor and the second vehicle body detection BS2 is also used as a vehicle exit sensor.

  By the way, in the car wash machine described in Patent Document 1, the car wash machine body travels within a range in which the first car body detection BS1 and the second car body detection BS2 detect the front end and the rear end of the car body, respectively. There was a problem that the car washing time was prolonged. That is, when the first vehicle body detection BS1 is also used as an entry sensor and the second vehicle body detection BS2 is also used as a departure sensor, the vehicle washing machine main body is used to detect the front end and the rear end of the vehicle body using the entry sensor and the departure sensor. It is necessary to drive the vehicle in a range where the vehicle is not detected by both the entrance sensor and the exit sensor (solid line and dotted line in FIG. 7), and there is a problem that the idle running distance not related to car washing becomes long and it takes time for car washing. It was. In addition, it is not preferable to provide a dedicated vehicle body detection sensor for self-running detection because the product cost increases.

  Further, in this car wash machine, when the first vehicle body detection means is also used as the vehicle shape sensor and the second vehicle body detection means is also used as the exit sensor, the position of the vehicle body detected by the vehicle shape sensor and the vehicle body detected by the exit sensor is determined. Deviation may occur. In other words, the car shape sensor detects the shape as far as the lower part of the car as much as possible, so it is installed at a lower point of 60cm above the ground, which is restricted by the Fire Service Law, while the exit sensor detects the rear end of the body of any car model. Because it is installed at a ground height of about 70 cm, which can be used for rear tires, etc., there is a problem that the detection position of the vehicle body differs between the vehicle shape sensor and the exit sensor, and the movement of the vehicle cannot be accurately recognized. there were.

Japanese Patent No. 4724815

  Therefore, the problem to be solved by the present invention is to provide a car wash device that can reliably recognize the self-run of the automobile at a necessary timing during the car wash without performing unnecessary idle running.

  In order to solve the above-mentioned problems, the present invention provides a main body frame provided with a car wash processing device, a travel detection means for detecting the travel position of the main body frame, a vehicle shape sensor for detecting the top surface shape of an automobile, and the vehicle shape sensor.

The travel position when the travel detection means detects the travel position of the main body frame with the vehicle body non-detection state as a starting point, and the vehicle body detection / non-detection is switched by the first vehicle body sensor, the vehicle shape sensor, and the second vehicle body sensor. And the travel distance between the travel positions is calculated and compared with the installation intervals of the first vehicle body sensor, the vehicle shape sensor, and the second vehicle body sensor, the self-travel of the vehicle is determined. .

  The self-running detection means is a travel position when the vehicle body sensor shifts from non-detection of the vehicle body to detection when the body frame travels, and a travel position when the vehicle body sensor switches from detection of the vehicle body non-detection to detection. When the travel distance is different from the installation interval of the vehicle shape sensor and the second vehicle body sensor, the self-running of the automobile is determined. Further, when the main body frame travels, the travel distance between the travel position when the first body sensor switches from vehicle body detection to non-detection and the travel position when the vehicle shape sensor switches from vehicle body detection to non-detection is the first. 1. When the installation interval of the vehicle body sensor and the vehicle shape sensor is different, the self-running of the automobile is determined.

  The self-propelled detection means determines that the vehicle is self-propelled when the second vehicle body sensor detects non-detection of the vehicle body again after detecting the vehicle body with the second vehicle body sensor when the main body frame travels. In addition, the self-propelling detection means is configured such that when the traveling distance from the detection of the vehicle body by the second vehicle body sensor to the non-detection of the vehicle body by the first vehicle body sensor is short when the main body frame travels, Judge that there was.

  The vehicle shape sensor is composed of a line sensor that forms a plurality of optical axes vertically with an automobile sandwiched in the width direction, and the vehicle body sensor is composed of a beam sensor that forms one optical axis with the automobile sandwiched in the width direction. When the vehicle shape sensor and the first vehicle body sensor determine self-propelling, the optical axis for detecting the vehicle body by the vehicle shape sensor is an optical axis that is substantially the same as the optical axis height of the first vehicle body sensor, and the vehicle shape sensor When the self-running is determined by the second vehicle body sensor, the optical axis for detecting the vehicle body by the vehicle shape sensor is the optical axis that is substantially the same as the optical axis height of the second vehicle body sensor.

  According to the present invention, when the main body frame travels using the vehicle shape sensor and the two vehicle body sensors, the self-running of the automobile is performed according to the positional relationship between the main body frame and the automobile (travel position of the main body frame). It can be detected, and it is possible to prevent accidents of the car washer and the car by taking measures such as stopping the car washer. In addition, it is a vehicle type sensor consisting of line sensors that form a plurality of optical axes above and below, and detects the vehicle body with an optical axis that is approximately the same height as the mounting height of the vehicle body sensor, thereby preventing detection displacement and ensuring a reliable vehicle. Can be detected.

The operation of the car wash control board 17 in the car wash apparatus configured as described above will be described.
The main body frame 1 is normally located at the rear end of the rails 3 and 3, and the entry sensor 10, the vehicle shape sensor 9, and the exit sensor 11 are all translucent, and the guide display 16 displays “accepting”. Waiting in state. When the car wash accepting device 12 accepts the car wash and the car wash accepting signal is sent from the car wash accepting device 12, the guide display 16 displays a message “Move forward” to prompt entry of the car. The car wash request signal is added with the car wash course / topping / projection car wash acceptance data selected and set at the time of the car wash acceptance. When the body frame 1 receives the car wash request signal, the reception confirmation signal is sent to the car wash acceptance device 12. Return it.

  When the car moves forward according to the guidance of the guide indicator 16 and the optical axis of the incoming sensor 10 changes from light transmission to light shielding to detect the vehicle body, the guide indicator 16 displays a “Please stop” guidance and the car. Urge to stop. Here, when the vehicle shape sensor 9 detects the vehicle body, it is determined that the vehicle has moved forward more than the stop position, and the guidance display 16 displays a message “Please move backward” to prompt the vehicle to move backward. Further, when the optical axis of the incoming sensor 10 changes from light blocking to translucent and the vehicle body is not detected, it is determined that the automobile has moved backward from the stop position, and the guide display 16 indicates “Please move forward”. Is displayed to encourage the car to move forward. Thus, the vehicle shape sensor 9 guides to a stop position where the vehicle body is not detected and the entry sensor 10 is in the vehicle body detection state, and when this stop state continues for a predetermined time, a stop signal is transmitted to the reception control boat 18 and a guide indicator A message “Start car wash. Please wait while the car is stopped” is displayed in 16, and the car wash starts.

  When the car wash is started, the main body frame 1 starts to go, and while the car shape sensor 9 recognizes the car shape of the car, the car detects the car surface detected by controlling the upper surface brush 4 and the side brushes 5 and 5 that follow. Brushing is performed by acting on the vehicle body along the shape. When the side brushes 5 and 5 clean the rear surface of the vehicle body, the main body frame 1 changes to go backward, and the top brush 4 and the side brushes 5 and 5 are controlled based on the vehicle shape recognized at the time of going forward, and the vehicle body is washed again. Do. When the main body frame 1 returns to the standby position, re-going is started and air is injected by the upper blower nozzle 6 and the side blower nozzles 7 and 7 on the basis of the vehicle shape recognized at the time of going forward, and the nozzle is brought closer to the vehicle body. Dry. In this way, the main body frame 1 is positioned on the rear end side of the automobile, and the car wash is completed.

  When the car wash is finished, the guide display 16 shows “The car wash is finished. “Please leave with advancing forward” is displayed. After this, if the car leaves and the exit sensor 11 is not detected, after waiting for a certain period of time, the guide display 16 will show “The car wash machine moves backward. “Please be careful” is displayed to prompt attention, and the main body frame 1 is returned to the start position.

  If the vehicle exit sensor 11 is in a detection state while the main body frame 1 is moving backward, the main body frame 1 stops traveling, and “the car wash machine moves backward. Output “Please note”. If the vehicle exit sensor 11 in the detected state turns to non-detection, the main body frame 1 continues to move backward, and if the main body frame 1 returns to the start position of the rear ends of the rails 2 and 2, the travel of the main body frame 1 is stopped. To do. Thus, when the main body frame 1 is retracted, the main body frame 1 is retracted while ensuring safety so as not to come into contact with a person or an automobile. When the main body frame 1 is returned to the start position, it returns and waits for the next car wash.

Next, an operation for monitoring the self-running of the automobile during the car wash will be described with reference to FIGS.
When the main body frame 1 starts to travel, the vehicle starts traveling in a state where the stop of the vehicle is confirmed (that is, the vehicle sensor 9 is light-shielded, the vehicle sensor 9 is light-transmitting, and the vehicle exit sensor 11 is light-transmitting). The travel position of the main body frame 1 is detected by the encoder 8.

  A storage unit that stores a travel position P1 when the vehicle shape sensor 9 detects the front end of the vehicle as the body frame travels, and a travel position P2 when the vehicle exit sensor 11 detects the front end of the vehicle by changing from light transmission to light shielding. 20 stored. Here, of the optical axis of the vehicle sensor 9, the mounting height of the vehicle exit sensor 11 is set so that the vehicle front end detected by the vehicle sensor 9 and the vehicle front end detected by the vehicle exit sensor 11 have the same height. It is determined that the front end of the automobile has been detected when the optical axis (here, optical axis B3) of the vehicle-shaped sensor 9 corresponding to the above-mentioned ground height of 70 cm changes from light transmission to light shielding.

  Subsequently, the travel distance a from the travel position P1 to the travel position P2 is calculated, and the travel distance a is compared with the installation interval A between the vehicle shape sensor 9 and the leaving sensor 11, and if a = A, the vehicle Judge that there is no self-propelled driving and continue the car wash. If a <A, it is determined that the vehicle has been traveling forward, and if a> A, it is determined that the vehicle has been traveling backward.

  As the vehicle travels, the storage unit 20 stores a travel position P3 when the incoming sensor 10 changes from light shielding to translucent and detects the rear end of the vehicle, and a travel position P4 when the vehicle shape sensor 9 detects the rear end of the vehicle. To remember. Here, of the optical axis of the vehicle type sensor 9, the attachment sensor 9 is attached so that the rear end of the vehicle detected by the vehicle exit sensor 11 and the rear end of the vehicle detected by the vehicle shape sensor 9 have the same height. It is determined that the rear end of the vehicle has been detected when the optical axis (here, optical axis B1) of the vehicle-shaped sensor 9 corresponding to a height of 60 cm above the ground is changed from light shielding to light transmission.

  Subsequently, the travel distance b from the travel position P3 to the travel position P4 is calculated, and the travel distance b is compared with the installation interval B between the vehicle entry sensor 10 and the vehicle shape sensor 9. Judge that there is no self-propelled driving and continue the car wash. If b <B, it is determined that the vehicle is traveling forward, and if b> B, it is determined that the vehicle is traveling backward.

  The traveling of the main body frame 1 stops at the position EP where the cleaning of the rear surface of the vehicle body by the side brushes 5 and 5 is completed. When the travel of the main body frame 1 is finished, the distance c from the start position SP to the travel position P2, the distance d from the travel position P2 to the travel position P3, and the travel distance e from the travel position P3 to the stop position EP are respectively set. Store in the storage unit 20.

  Thus, when the main body frame 1 travels, it can be determined whether or not the vehicle has self-propelled while the main body frame 1 moves from the travel position P1 to the travel position P2 and between the travel position P3 and the travel position P4. it can. Further, while the main body frame 1 moves from the travel position P2 to the travel position P3, if the exit sensor 11 changes from light shielding to translucency, it is determined that the vehicle is traveling backward, and the exit sensor 11 If the travel distance d from the time when the vehicle enters the light-shielding sensor 9 to the time when the vehicle entry sensor 9 changes from light-shielding to light-transmitting is abnormally short, it is determined that the vehicle has traveled forward. Usually, the installation interval A + B between the entrance sensor 9 and the exit sensor 11 is 2 to 3 m and is set to be shorter than the length of a general light vehicle. Therefore, after the exit sensor 11 detects the vehicle body. A certain amount of distance is generated until the entry sensor 9 no longer detects the vehicle body, but if this distance is abnormally short (for example, the entry sensor 9 does not detect the vehicle immediately after the exit sensor 11 detects the vehicle body). Etc.), it is judged that there was a self-propelled forward movement of the car.

When the main body frame 1 goes backward, the vehicle shape of the automobile is not recognized by the vehicle shape sensor 9. Therefore, when the main body frame 1 goes backward, self-running detection is performed by the incoming sensor 10 and the leaving sensor 11. ing.
First, the main body frame 1 returns from the stop position EP, and the in-vehicle sensor 10 changes from light transmission to light shielding to detect the rear end of the vehicle body, and detects the travel position P3. The distance e ′ from the actually measured stop position EP to the travel position P3 is compared. If e ′ = e, it is determined that the car is not self-propelled and the car wash is continued. If e ′ <e, it is determined that the vehicle is traveling backward, and if e ′> e, it is determined that the vehicle is traveling forward.

  Next, the traveling position P2 when the vehicle exit sensor 11 changes from light shielding to translucent and detects the front end of the vehicle body is detected, and the traveling distance d stored in the forward direction and the distance from the actually measured traveling position P3 to the traveling position P2 are detected. Compare d '. If d '= d, it is determined that the car is not self-propelled and the car wash is continued. If d '<d, it is determined that the vehicle is traveling backward, and if d'> d, it is determined that the vehicle is traveling forward.

  Further, it is detected that the main body frame 1 has reached the start position SP, and the travel distance c stored in the forward direction is compared with the distance c ′ from the actually measured travel position P2 to the travel position SP. If c '= c, it is determined that the car is not self-propelled and the car wash is continued. If c '<c, it is determined that the vehicle is traveling backward, and if c'> c, it is determined that the vehicle is traveling forward.

  In addition, since the vehicle shape of the vehicle is not recognized by the vehicle shape sensor 9 even when the main body frame 1 is re-going, self-running detection is performed by the entering sensor 10 and the leaving sensor 11. The method includes the distance c from the start position SP to the travel position P2, the distance d from the travel position P2 to the travel position P3, and the stop position from the travel position P3, which are stored in the storage unit 20 when the main body frame 1 travels. This is equivalent to a return trip in which the travel distance e to the EP is compared with the measured value.

  Although the embodiment described above shows an example implemented in a type of car wash machine that includes a brush device and performs brushing cleaning, the same applies to a type of car wash machine that does not include a brush device and that cleans the vehicle body with high-pressure spray or the like. Can do. Further, it is possible to adopt a type in which a car wash machine is stationary and a car is transported by a carriage, or a type in which the car wash machine and the car travel together.
