Technical Field

[0001] The present invention relates to a vehicle processing device.

Background Art

[0002] Japanese Patent Application Laid-Open No. 2021-41907 (hereinafter referred to as "Patent Document 1") describes a vehicle processing device for washing large vehicles such as box cars, buses, flat bodies, and trailers. Rails are laid on the laying surface according to the vehicle length of the large vehicle in the vehicle processing device.

[0003] When the vehicle processing device detects that a large vehicle has stopped at a designated location in front of the vehicle processing device main body, it starts the washing process. The vehicle processing device travels from one side of the rail to the other side, that is, from the front side to the rear side of the large vehicle, and performs a washing process on the vehicle body of the large vehicle while traveling. When the washing process is completed, the vehicle processing device waits until it detects the reverse movement of the large vehicle at the other end of the rail (the rear side of the large vehicle), and returns to its original position when it detects the exit of the large vehicle.

Summary of the Invention

Problems to be Solved by the Invention

[0005] In a vehicle processing device such as Patent Document 1, rails are provided according to the vehicle length of a large vehicle. After the washing process is completed, a large vehicle that has exited the vehicle processing device turns around behind the vehicle processing device for direction change. Therefore, when installing a vehicle processing device such as Patent Document 1, in addition to the floor area for laying the rails, an area where the large vehicle turns around must also be considered, and a vast floor area must be secured for the installation of the vehicle processing device.

[0006] The applicant thought that it would be possible to provide a vehicle processing device that can reverse a large vehicle from the rear to the front of the vehicle processing device so that it is not necessary to secure a large area behind the vehicle processing device.

[0007] An object of the present invention is to provide a vehicle processing device that can reverse a vehicle from the rear to the front of the vehicle processing device.

Best Mode for Carrying Out the Invention

[0011] In the embodiments of the present invention, if necessary, the description will be divided into a plurality of sections or the like for explanation. In principle, however, they are not unrelated to each other, and one is related to a part or all of the other as a modification example, details, etc. For this reason, in all the figures, members having the same function are denoted by the same reference numerals, and repeated description thereof is omitted.

[0012] Also, regarding the number of components (including the number, numerical value, quantity, range, etc.), unless otherwise specified or limited to a specific number in principle, it is not limited to that specific number, and it may be more than or less than the specific number. Further, when referring to the shape of components or the like, unless otherwise specified or considered not to be so in principle, it includes those substantially approximate or similar to the shape or the like.

[0013] Hereinafter, the vehicle processing apparatus of the present invention will be described with reference to the drawings. FIG. 1 is a schematic front view of the vehicle processing apparatus, and FIG. 2 is a side view of the vehicle processing apparatus shown in FIG. 1. FIGS. 1 and 2 are shown partially in broken lines for ease of explanation. Also, the left - right direction in FIG. 1 is referred to as the width direction of the vehicle processing apparatus, and the up - down direction is referred to as the standing direction or the height direction of the vehicle processing apparatus. Further, the left direction in FIG. 2 is referred to as the front direction of the vehicle processing apparatus, and the right direction is referred to as the rear direction of the vehicle processing apparatus. The vehicle processing apparatus 10 according to the present embodiment has a processing function of washing a large vehicle 80 such as a box car, a bus, a flat - body, or a trailer. The vehicle processing apparatus 10 includes a main body portion 11 having a portal shape and is erected and fixed on the ground G (paved surface). The main body portion 11 includes leg portions 12, 12 and a beam portion 13 supported by the leg portions 12, 12. Also, the surface facing the vehicle 80 passing through the portal - shaped main body portion 11 is open. The vehicle processing apparatus 10 sprays a cleaning liquid or brushes toward the vehicle 80 from the open surface.

[0014] The main body portion 11 is provided with a top brush 17 on the beam portion 13. The top brush 17 has a rotation axis along the width direction and moves while rotating in the upright direction of the vehicle processing apparatus 10. The top brush 17 can mainly clean the upper surface of the vehicle 80. Further, the main body portion 11 is provided with side brushes 20, 20 on the leg portions 12, 12. The side brushes 20, 20 have a rotation axis along the upright direction and perform opening and closing movement while rotating in the width direction of the vehicle processing apparatus 10. The side brushes 20, 20 can mainly clean the front, side, and rear surfaces of the vehicle 80. Fan-shaped hair materials (for example, those disclosed in the registered utility model No. 3087803, which is a known technique) are fixed to the rotation axes of the top brush 17 and the side brushes 20, 20 by rivets or the like. Therefore, when the top brush 17 and the side brushes 20, 20 rotate, the hair materials spread around the rotation axes.

[0015] The main body portion 11 is provided with nozzles 23 for injecting cleaning liquid toward the vehicle 80. The nozzles 23 are provided on the beam portion 13 and the leg portions 12, 12. The nozzles 23 provided on the beam portion 13 inject the cleaning liquid mainly toward the upper surface of the vehicle 80. The nozzles 23 provided on the leg portions 12, 12 inject the cleaning liquid mainly toward the side surfaces of the vehicle 80.

[0016] The vehicle processing apparatus 10 is provided with entry sensors 14, 14 provided on the leg portions 12, 12 of the main body portion 11 for detecting the vehicle 80 at a position higher than the ground G. The entry sensors 14, 14 have units provided with transmissive photoelectric sensors 51, 51 as detection elements. The entry sensors 14, 14 are provided opposite to each other so that the light emitted from one entry sensor 14 (photoelectric sensor 51) can be received by the other entry sensor 14 (photoelectric sensor 51). The vehicle processing apparatus 10 can detect the vehicle 80 entering between the entry sensors 14, 14 based on the passing and blocking of light between the photoelectric sensors 51. Further, the entry sensors 14, 14 are provided such that the other entry sensor 14 is at a higher position than one entry sensor 14. By providing them in this way, the optical axis emitted from the photoelectric sensor 51 is inclined with respect to the ground G, and the vehicle 80 can be detected over a wide range.

[0017] The vehicle processing device 10 is provided with vehicle height sensor units 15, 15 that detect the vehicle height of the vehicle 80. The vehicle height sensor units 15, 15 are supported by arms 21, 21 protruding from the legs 12, 12. The vehicle height sensor units 15, 15 have units including transmissive photoelectric sensors 52 to 55. By providing the vehicle height sensor units 15, 15 to face each other, the light emitted from one vehicle height sensor unit 15 (photoelectric sensors 52 to 55) can be received by the other vehicle height sensor unit 15 (photoelectric sensors 52 to 55). The vehicle processing device 10 can detect the height of the vehicle 80 entering between the vehicle height sensor units 15, 15 based on the light transmission and light blocking between the photoelectric sensors 52 to 55.

[0018] The photoelectric sensors 52 to 55 are arranged linearly side by side along the standing direction. The photoelectric sensor 55 is provided at a position higher than the photoelectric sensor 54. Also, the photoelectric sensor 54 is provided at a position higher than the photoelectric sensor 53, and the photoelectric sensor 53 is provided at a position higher than the photoelectric sensor 52. That is, they are provided in the order of photoelectric sensors 52, 53, 54, 55 from the ground G side. Also, the vehicle height sensor units 15, 15 are provided in front of the legs 12, 12 by the arms 21, 21 as described above. Thereby, even when the top brush 17 moves up and down, it does not contact the vehicle height sensor unit 15. Also, the vehicle height sensor units 15, 15 are provided at the same height from the ground G so that the optical axes emitted from the opposing photoelectric sensors 52, 53, 54, 55 are horizontal. In the embodiment of the present invention, four pairs of photoelectric sensors 52 to 55 are described, but the number is not limited to this.

[0019] The vehicle height sensor units 15, 15 are provided in front of the vehicle entry sensor units 14, 14. The vehicle processing device 10 has a processing function for washing large-sized vehicles 80 such as box cars, buses, flat bodies, and trailers. Among such large-sized vehicles 80, as shown in FIG. 2, there are some in which the lower part (e.g., bumper) protrudes more than the upper part (e.g., windshield). Therefore, when detecting the entry of the vehicle 80, the vehicle height sensor units 15, 15 are provided in front of the vehicle entry sensor units 14, 14. By doing so, when the lower part (e.g., bumper) of the vehicle 80 is detected by the vehicle entry sensor units 14, 14, the upper part (e.g., windshield) of the vehicle 80 can be detected by the vehicle height sensor units 15, 15.

[0020] The vehicle processing device 10 is provided with position sensor units 16, 16 for detecting the position of the vehicle 80 in the main body 11. The position sensor units 16, 16 are provided facing the inner surfaces of the leg portions 12, 12. The position sensors 16, 16 are provided at a position lower than the vehicle height sensors 15, 15 so that they can detect the lower part of the vehicle 80 in the same manner as the vehicle entry sensor units 14, 14. The position sensor units 16, 16 of the leg portions 12, 12 have a unit including transmissive photoelectric sensors 56 to 59. By providing the position sensor units 16, 16 facing each other, the light emitted from one position sensor unit 16 (photoelectric sensors 56 to 59) can be received by the other position sensor unit 16 (photoelectric sensors 56 to 59). Also, the position sensor units 16, 16 are provided such that the other position sensor unit 16 is at a higher position than one position sensor unit 16. By providing them in this way, the optical axes emitted from the photoelectric sensors 56 to 59 are inclined with respect to the ground G, and the vehicle 80 can be detected over a wide range.

[0021] The photoelectric sensors 56 to 59 provided in the main body 11 are linearly arranged along the front-rear direction of the vehicle processing device 10. The photoelectric sensor 56 is provided in front of the photoelectric sensor 57. Also, the photoelectric sensor 57 is provided in front of the photoelectric sensor 58, and the photoelectric sensor 58 is provided in front of the photoelectric sensor 59. That is, they are arranged from the front to the rear in the order of the photoelectric sensors 56, 57, 58, 59. By having a plurality of photoelectric sensors 56 to 59, the position of the vehicle 80 passing through the main body 11 can be detected.

[0022] As described above, when the side brushes 20, 20 rotate, the bristles spread around the rotation axis. The dashed line in Figure 2 represents the state when the side brushes 20, 20 are rotating, and the long dashed line represents the state when the side brushes 20, 20 are not rotating. The front-rear direction distance L1 between the photoelectric sensor 56 and the photoelectric sensor 59 is provided to be longer than the width of the rotation axis of the side brush and shorter than the width of the side brushes 20, 20 during rotation. By doing so, the light emitted from the photoelectric sensors 56, 59 is blocked by the bristles of the rotating side brushes 20, 20. Also, the front-rear direction distance L2 between the photoelectric sensor 57 and the photoelectric sensor 58 is provided to be longer than the rotation axis width (diameter) of the side brushes 20, 20 and shorter than L1. By doing so, the light emitted from the photoelectric sensors 57, 58 is provided to pass through without being blocked by the non-rotating side brushes 20, 20. That is, when the side brushes 20, 20 are rotating, the photoelectric sensors 56 to 59 are blocked, and when the side brushes 20, 20 are not rotating, the photoelectric sensors 56 to 59 allow light to pass through. In this way, the photoelectric sensors 56 to 59 are provided in consideration of the distances L1 and L2 when the side brushes 20, 20 are rotating and not rotating.

[0023] The positions where the photoelectric sensors 56 to 59 are provided will be described in more detail. When the vehicle 80 enters from the front of the main body 11, when the vehicle processing device 10 detects the light shielding of the photoelectric sensors 56, 56, it determines that the front surface (front end) of the vehicle is located at the positions of the photoelectric sensors 56, 56. As described above, the side brushes 20, 20 clean the front surface of the vehicle. Therefore, when the vehicle 80 stops at the positions of the photoelectric sensors 56, 56, the bristles of the side brushes 20 that rotate on the front surface of the vehicle 80 can be brought into contact. By the contact of the bristles, the front surface of the vehicle 80 can be firmly brushed. Also, when the vehicle 80 enters from the front of the main body 11, when the vehicle processing device 10 detects the light shielding of the photoelectric sensors 56, 56 and the photoelectric sensors 57, 57, it determines that the front surface of the vehicle 80 has stopped at the positions of the photoelectric sensors 57, 57. If the front surface of the vehicle 80 is detected at the positions of the photoelectric sensors 57, 57, there is a risk that the rotating shafts of the side brushes 20, 20 will come into contact with the vehicle. Therefore, when it is determined that the vehicle 80 has stopped at the positions of the photoelectric sensors 57, 57, the vehicle processing device 10 does not drive the side brushes 20, 20.

[0024] That is, when the vehicle 80 enters from the front of the main body 11, when the vehicle processing device 10 detects the light shielding of the photoelectric sensors 56, 56 and the light passing of the photoelectric sensors 57, 57, it drives the side brushes 20, 20. However, when it detects the light shielding of the photoelectric sensors 56, 56 and the photoelectric sensors 57, 57, it does not drive the side brushes 20, 20.

[0025] Furthermore, when the vehicle 80 advances from the front of the main body 11, when the vehicle processing device 10 detects the passing of light through the photoelectric sensors 58, 58 and the blocking of light by the photoelectric sensors 59, 59, it determines that the rear surface (rear end) of the vehicle is located at the position of the photoelectric sensors 59, 59. By stopping the rear surface of the vehicle 80 at the position of the photoelectric sensors 59, 59, the bristles of the side brush 20 can be brought into contact with the rear surface of the vehicle 80, and the rear surface can be thoroughly brushed. However, when the vehicle 80 advances from the front of the main body 11 and the vehicle processing device 10 detects the blocking of light by the photoelectric sensors 58, 58 and the photoelectric sensors 59, 59, there is a risk that the rotating shaft may come into contact with the vehicle when the side brushes 20, 20 rotate. Therefore, when the photoelectric sensors 58, 58 and the photoelectric sensors 59, 59 are in the light-blocked state, the vehicle processing device 10 does not drive the side brushes 20, 20.

[0026] That is, when the vehicle 80 enters from the front of the main body 11 and the vehicle processing device 10 detects the passing of light through the photoelectric sensors 58, 58 and the blocking of light by the photoelectric sensors 59, 59, it drives the side brushes 20, 20. However, when it detects the blocking of light by the photoelectric sensors 58, 58 and the photoelectric sensors 59, 59, it does not drive the side brushes 20, 20.

[0027] In this way, by setting the distance in the front-rear direction between the photoelectric sensor 56 and the photoelectric sensor 59 as L1, the bristles of the side brushes 20, 20 that rotate and spread can be brought into contact with the vehicle 80. Also, by setting the distance in the front-rear direction between the photoelectric sensor 57 and the photoelectric sensor 58 as L2, it is possible to prevent the rotating shafts of the side brushes 20, 20 from coming into contact with the vehicle 80.

[0028] The vehicle processing device 10 is provided with, for example, guide lights 18 and 19 that light up in red and blue on the main body 11. The guide light 18 is provided on the inner surface of the driver's side leg 12 and guides the driver to move forward, stop, or reverse. By providing the guide light 18 on the inner surface of the leg 12, it is easy for the driver passing through the main body 11 to visually recognize it. The guide light 19 is provided on the rear surface of the driver's side leg 12 and, like the guide light 18, guides the driver to move forward and stop. By providing the guide light 19 on the rear surface of the leg 12, when the vehicle 80 is located behind the main body 11, the driver can directly confirm it or indirectly confirm it through the side mirror. For example, when it is desired to move the vehicle 80 forward, the guide lights 18 and 19 light up blue; when it is desired to stop the vehicle 80, the red light is lit; and when it is desired to reverse the vehicle 80, both the blue and red lights are lit. Also, when the vehicle 80 approaches a predetermined position, the lamp may be changed from lighting to flashing to guide the driver to drive slowly.

[0029] The vehicle processing device 10 is provided with an operation unit 17 in front of the main body 11. The operation unit 17 has, for example, an "upper surface cleaning button" for cleaning the upper surface in addition to the side surface of the vehicle 80 and a "lower part cleaning button" for cleaning the lower surface in addition to the side surface of the vehicle 80. The driver can select the cleaning part of the vehicle 80 by operating the operation unit 17. When an arbitrary cleaning part is selected by the operation unit 17, after the vehicle processing device 10 detects the entry of the vehicle 80, it starts cleaning processes such as cleaning and brushing. The operation unit 17 is provided with a reception lamp (not shown) that notifies the driver that cleaning is possible (waiting for reception), etc.

[0030] Figure 3 is a block diagram showing the control system of the vehicle processing device 10 shown in Figure 1. The vehicle processing device 10 is provided with a control unit 30 that enables the vehicle 80 to exhibit various processing functions. The control unit 30 is electrically connected to the operation unit 17, the guide lights 18 and 19, the top brush 17, the side brushes 20 and 20, and the photoelectric sensors 51 to 59. The operation unit 17 is provided with, for example, selection buttons (such as an "upper surface cleaning button" and a "lower part cleaning button") for selecting the cleaning part of the vehicle 80.

[0031] The control unit 30 includes, for example, a position detection unit 31 that detects the position of the vehicle 80 from the photoelectric sensors 51, 56 to 59. The position detection unit 31 detects the position of the vehicle 80 and outputs a command to the guide light control unit 36. The guide light control unit 36 controls the lighting of the blue lamp and the red lamp of the guide lights 18 and 19 according to the position of the vehicle 80. The current detection unit 32 detects the current value of the motor that drives the top brush 17, determines the contact state between the top brush 17 and the vehicle 80, and outputs a command to the lifting and lowering control unit 33. The lifting and lowering control unit 33 moves the top brush 17 up and down according to the position of the vehicle 80 from the current detection unit 32 and the position detection unit 31. The current detection unit 34 detects the current value of the motor that drives the side brushes 20, 20, determines the contact state between the side brushes 20, 20 and the vehicle 80, and outputs a command to the opening and closing control unit 35. The opening and closing control unit 35 moves the side brushes 20, 20 open and closed according to the position of the vehicle 80 from the current detection unit 34 and the position detection unit 31.

[0032] In addition, the control unit 30 includes a data storage unit 36 that stores various data and the like. In the data storage unit 36, the upper and lower current thresholds for determining the contact state from the amount of current increase when the top brush 17 and the side brushes 20, 20 are brought into contact with the vehicle 80, and the coefficients indicating the current change characteristics for each cleaning part are tabulated and stored for each cleaning part (for example, the front, top, rear, side). That is, brushing is performed by raising and lowering the top brush 17 and opening and closing the side brushes 20, 20 so that the current value that rises when the top brush 17 and the side brushes 20, 20 are brought into contact with the vehicle 80 is between the upper and lower current thresholds stored in the data storage unit 36. Further, the data storage unit 36 also stores the coefficients indicating the current values when the top brush 17 and the side brushes 20, 20 are not in contact with the vehicle 80. That is, the vehicle processing device 10 can detect whether the top brush 17 and the side brushes 20, 20 are in contact with the vehicle 80 by storing the coefficients during the idling of the brushes.

[0033] Next, the cleaning process performed by the vehicle processing device 10 on the vehicle 80 will be described. As described above, the vehicle processing device 10 mainly cleans large vehicles 80 such as box cars, buses, flat bodies, and trailers. In this embodiment, a trailer (vehicle 80) as shown in FIG. 2 will be described as an example.

[0034] <Receiving standby> FIG. 4 is a flowchart for explaining the receiving standby of the vehicle processing device 10. First, when the vehicle processing device 10 is in the receiving standby for receiving the cleaning process, it checks the light passing of the photoelectric sensors 51 to 59 (S110). Also, the top brush 17 and the side brushes 20, 20 are idled and the current value of the motor is measured (hereinafter referred to as idling measurement). The measured idling measurement value is stored in the data storage unit 36. When in receiving standby, the guide lights 18, 19 may be turned off, or a lamp indicating that it is in receiving standby may be turned on.

[0035] The driver brings the vehicle 80 closer to the main body 11 and selects a desired cleaning part with the operation unit 17 (S130). Then, the vehicle 80 is advanced into the main body 11 until the blue lamp of the guide light 18 lights up (S140). At this time, the vehicle processing device 10 detects the entry of the vehicle 80 when the light emitted from the photoelectric sensor 51 is blocked by the lower part (such as the bumper) of the vehicle 80. And when the vehicle 80 enters up to the photoelectric sensor 56 of the position sensor unit 15 (S160), the lamps of the guide lights 18, 19 are lit from blue to red to prompt the driver to stop. The vehicle processing device 10 shifts from receiving standby to the cleaning process based on the signal from the operation unit 17 and the output values from the photoelectric sensors 51 and the photoelectric sensor 56 of the position sensor unit 16. At S160, when the vehicle processing device 10 detects the light blocking of the photoelectric sensors 51, 56, 57, it lights up the color lamp and the red lamp of the guide lights 18, 19, prompts the vehicle 80 to reverse, and guides the vehicle 80 to stop between the photoelectric sensor 56 and the photoelectric sensor 57 (L3) at the front end.

[0036] <Cleaning process> Figs. 5 and 6 are flowcharts for explaining the cleaning process of the vehicle processing device 10. The vehicle processing device 10 starts the cleaning process of the cleaning part at the operation unit 17. In this embodiment, the cleaning of the upper surface is selected as an example for explanation. When the vehicle processing device 10 detects the light shielding of the photoelectric sensor 56 of the position sensor unit 16, it detects the height of the vehicle 80 based on the output values of the photoelectric sensors 52 to 55 of the vehicle height sensor unit 15 (S210). In this embodiment, the photoelectric sensors 52 to 55 are shielded by the vehicle 80. Further, the cleaning liquid is sprayed from the nozzle 23 toward the vehicle 80, and the top brush 17 and the side brushes 20, 20 are rotationally driven (S220, S230). The side brushes 20, 20 brush the front surface of the vehicle 80 by opening and closing movement. When the front surface of the vehicle 80 is brushed by the side brushes 20, 20, the top brush 17 descends while rotating to the height detected by the vehicle height sensor unit 15 (photoelectric sensors 52 to 55) earlier (the position of the photoelectric sensor 55). At this time, the vehicle processing device 10 measures the motor current value of the top brush 17 from the current detection unit 32. The current value that rises when the top brush 17 contacts the vehicle 80 is stored in the data storage unit 36, and the lifting and lowering control unit 33 controls the lifting and lowering of the top brush 17 according to the shape of the vehicle 80 so that it is between the upper and lower current threshold values. This control method is also performed for the side brushes 20, 20.

[0037] When the top brush 17 finishes brushing the upper surface of the vehicle 80 and the side brushes 20, 20 finish brushing the front surface, the side brushes 20, 20 return to the position during reception waiting and stop rotating (S240). As described above, when the side brushes 20, 20 rotate, the photoelectric sensors 56 to 59 are blocked from light, and when they are not rotating, light passes through. The vehicle processing device 10 lights the guiding lights 18, 19 that are lit in red in blue, and guides the driver to move the vehicle 80 forward to the position of the photoelectric sensor 59 (S250). Specifically, the driver moves the vehicle 80 forward. The vehicle processing device 10 detects the blocking of the photoelectric sensors 56, 57 and the passing of light through the photoelectric sensors 58, 59. When the vehicle 80 moves further forward, the vehicle processing device 10 detects the blocking of the photoelectric sensors 56, 57, 58 and the passing of light through the photoelectric sensor 59. Then, when the vehicle 80 moves forward to the position of the photoelectric sensor 59, the vehicle processing device 10 detects the blocking of the photoelectric sensors 56 to 59 (S260), and lights the guiding lights 18, 19 from blue to red (S270). The driver who confirms this stops the vehicle 80. While the vehicle 80 moves forward from the photoelectric sensor 56 to the photoelectric sensor 59, the vehicle processing device 10 does not rotate (stops) the side brushes 20, 20.

[0038] After that, the vehicle processing device 10 rotationally drives the side brushes 20, 20 and brushes the side surface of the vehicle 80 while moving them open and closed. The top brush 17 also brushes the upper surface of the vehicle 80 (S280). After brushing the upper surface and the side surface of the vehicle 80 and when the current value from the motor that drives the brush reaches a predetermined current value, the vehicle processing device 10 lights the lamps of the guiding lights 18, 19 from red to blue, and guides the vehicle 80 to move forward. The driver confirms this and slowly moves the vehicle 80 forward. The vehicle processing device 10 continuously rotates the side brushes 20, 20 and the top brush 17, and brushes the side surface and the upper surface while moving the vehicle 80 forward.

[0039] As described above, the vehicle processing device 10 is fixedly installed. Even if rails are not provided according to the vehicle length of large vehicles, the cleaning process can be performed by the vehicle 80 passing through the main body 11.

[0040] When the vehicle processing device 10 detects that the vehicle 80 is moving forward and the light transmission of the photoelectric sensor 51 (S300), it blinks the blue lamps of the guiding lights 18 and 19 and guides the driver to move the vehicle forward slowly (S310). At this time, when the current value from the motors driving the side brushes 20 and 20 reaches a predetermined current value, the vehicle processing device 10 stops the side brushes 20 and 20 (S330). When the rear part of the vehicle 80 slowly moves forward to the position of the photoelectric sensor 59, the vehicle processing device 10 detects the light transmission of the photoelectric sensor 51, the light transmission of the photoelectric sensors 56 to 58, and the light shielding of the photoelectric sensor 59 (S340). The vehicle processing device 10 lights the lamps of the guiding lights 18 and 19 from blue blinking to red to guide the vehicle 80 to stop. When the rear end of the vehicle 80 stops at the position of the photoelectric sensor 59, the side brushes 20 and 20 are moved open and closed to brush the rear surface of the vehicle 80 (S360). When the cleaning of the rear surface of the vehicle 80 is completed, the vehicle processing device 10 ends the cleaning process.

[0041] In this way, the vehicle processing device 10 can detect the position of the vehicle 80 passing through the main body 11 by non-rotating the side brushes 20 and 20.

[0042] If the vehicle processing device 10 detects the light transmission of the photoelectric sensors 51 and 56 to 59 (S410), it determines that the vehicle 80 has passed through the main body 11, and lights the blue lamp and the red lamp of the guiding lights 18 and 19 to guide the vehicle 80 to reverse (S420). However, when the vehicle 80 cannot be detected to reverse even after guiding it to reverse for a predetermined time (S430), the vehicle processing device 10 ends the cleaning process.

[0043] <Forward and reverse movement of the vehicle> FIG. 7 is a flowchart for explaining the reverse and forward movement of the vehicle processing device 10. The reverse and forward movement means reversing the vehicle 80 located behind the main body 11 and then moving the vehicle backward from behind the main body 11 to the front. The vehicle processing device 10 lights the blue and red lamps of the guide lights 18 and 19 to guide the driver so that the vehicle 80 reverses and moves forward (S510). The driver who has confirmed this slowly reverses the vehicle 80. When the vehicle 80 reverses, the vehicle processing device 10 detects the light shielding of the photoelectric sensors 56 to 59 and the light shielding of the photoelectric sensor 51 (S520).

[0044] When the vehicle processing device 10 detects the light shielding of the photoelectric sensors 56 to 59 and the light shielding of the photoelectric sensor 51 for a predetermined time, the vehicle processing device 10 determines that the vehicle 80 is performing reverse and forward movement and does not inject the cleaning liquid from the nozzle.

[0045] When the vehicle 80 further reverses, the vehicle processing device 10 detects the light passing of the photoelectric sensor 59 and detects the light shielding of the photoelectric sensors 56 to 58 and the light shielding of the photoelectric sensor 51 (S530). Thereafter, it detects the light passing of the photoelectric sensors 59 and 58 and detects the light shielding of the photoelectric sensors 56, 57 and the photoelectric sensor 51 (S540). Also, it detects the light passing of the photoelectric sensors 59, 58, 57 and detects the light shielding of the photoelectric sensor 56 and the photoelectric sensor 51 (S550). Furthermore, it detects the light passing of the photoelectric sensors 59, 58, 57, 56 and detects the light shielding of the photoelectric sensor 51 (S560). Finally, it detects the light passing of the photoelectric sensors 59, 58, 57, 56 and the light passing of the photoelectric sensor 51 (S5700). If, during the reverse and forward movement of the vehicle 80, for example, when the photoelectric sensors 59 and 58 pass light (S540), the vehicle 80 moves forward and the photoelectric sensor 58 is shielded again, the vehicle processing device 10 is in the reverse and forward movement process, so the cleaning liquid is not ejected from the nozzle.

[0046] That is, after the vehicle processing device 10 detects the light shielding of the photoelectric sensors 56 to 59 and 51 for a predetermined time, when it detects that the light passes through the photoelectric sensors 59, 58, 57, 56, and 51 in this order provided from the rear of the main body 11, it can be determined that the vehicle 80 is moving backward and then forward. During that time, the cleaning liquid is not sprayed from the nozzles. After that, when the vehicle processing device 10 detects the light passing through the position sensor units 16, 16 and the entry vehicle sensor units 14, 14 for a predetermined time, it determines that the backward and forward movement of the vehicle 80 has ended.

[0047] When the vehicle processing device 10 determines that the backward and forward movement of the vehicle 80 has ended, it shifts to the reception standby state and measures the idling of the top brush 17 and the side brushes 20, 20.

[0048] In this way, the vehicle processing device 10 can move the vehicle 80 backward and then forward from the main body 11. Also, as described above, during the backward and forward movement, since the vehicle processing device 10 does not spray the cleaning liquid from the nozzles, the driver can safely move backward without the field of vision being blocked by the cleaning liquid.

[0049] Normally, when the vehicle processing device detects the light shielding of the photoelectric sensors 51, 56 to 59, it determines that the vehicle has entered the main body and starts the car wash. Then, the vehicle processing device sprays the cleaning liquid from the nozzles toward the vehicle or drives the brushes. That is, the vehicle cannot exit from the rear of the main body part toward the front. However, since the vehicle processing device 10 has a backward and forward exit process, the vehicle 80 can be moved backward and then exited.

[0050] In the embodiment of the present invention, a large vehicle has been described as an example, but it may be a vehicle such as a regular passenger car, a light vehicle, or a small passenger car without being limited to this.

[0051] As described above, the embodiment of the present invention has been explained, but the present invention is not limited to the above embodiment and can be changed without departing from the gist of the shape and configuration.
