The vehicle processing device 10 includes a travel motor 13 in a body portion 11 . The traveling motor 13 has a function of causing the main body 11 to travel via the wheels of the main body 11 . The main body 11 also includes a travel encoder 18 . The travel encoder 18 has a function of outputting a pulse signal each time the body portion 11 travels a unit distance. Therefore, the vehicle processing device 10 can grasp the position information of the main body 11 traveling on the rail 14 . When the main body 11 has the left end of the rail 14 in FIG. Go-around.

The vehicle processing device 10 has a reception unit 15 . The reception part 15 is provided upright on the laying surface G as shown in FIG. The reception unit 15 is configured to accept tolls, key inputs (for example, course selection, start, cancellation), and voice guidance, and has a function of accepting instructions from the driver of the vehicle C.

The vehicle processing device 10 also includes a gate 16 . As shown in FIG. 1 , the gate 16 is provided on the laying surface G separately from the body portion 11 between the rail 14 and the reception portion 15 in front of the body portion 11 .

Then, the stopped vehicle C is washed with shampoo, wax, and the like. When the car wash is finished, the guide display unit 17 prompts the user to exit.

The main body 11 has vehicle detection devices 30, 30 in front of the legs 12, 12 to prevent contact with the vehicle C when reciprocating on the rail 14. - 特許庁
The vehicle detection device 30 can detect when the vehicle enters the main body 11 before the side of the vehicle, for example, the side mirror that protrudes the most from the side, contacts the inner side of the leg 12 (broken line in FIG. 3). As such, it has a detection bar 32 .
The detection bar 32 (vehicle detection portion) is shaped like an elongated rod and is wrapped with an elastic member so as not to damage the surface of the vehicle. In addition, it is provided along the height direction of the leg 12 so that detection can be performed even when the height at which the side mirror is attached differs depending on the type and height of the vehicle.

4 is a perspective view of the vehicle detection device 30. FIG. A dashed line in the figure represents a state in which the vehicle detection device 30 has detected a vehicle. 5 is a top view of the vehicle detection device 30, and FIG. 6 is a top view showing a state in which the vehicle detection device 30 detects a vehicle. Also, FIGS. 5 and 6 are partly seen through for ease of explanation.
The detection bar 32 is supported by a support portion 31 that protrudes forward from the leg 12 and inward from the inner surface of the leg 12 .
A support hole 35 is provided in the support part 31 , and one end of the detection bar 32 passes through the support hole 35 . Furthermore, a detection bar hole 45 is provided at one end of the detection bar 32 passing through the support hole 35 . The fastener 33 penetrates through the detection bar hole 45 . Since the diameter of the support hole 35 is slightly larger than the diameter of the detection bar 32, the fastener 33 serves as a stopper to prevent the detection bar 32 from dropping due to its own weight.
In other words, since the detection bar 32 can rotate around the support hole 35, the impact of contact with the vehicle C can be softened. Since it is wrapped, the vehicle C is prevented from being damaged.

Vehicle detector 30 has an actuating arm 36 . One end 36 a of the operating arm 36 is connected with a belt 37 so as to link the detection bar 32 . The belt 37 forms a loop through which the detection bar 32 passes. Moreover, both ends are fixed to the end portion 36a. As a result, when the detection bar 32 comes into contact with the vehicle C and is displaced, the operating arm 36 can move via the belt 37 .

The vehicle detection device 30 includes a cover 39 that partially covers the actuating arm 36 . The cover 39 is supported by a support rod 42 horizontally projecting from the front of the leg 12 and covers a part of the operating arm 36 and a detection switch 38 for detecting the operation of the operating arm 36 .

The cover 39 has a substantially rectangular parallelepiped shape and is partially open. An actuating arm 36 is inserted into the opening. A spring 44 is provided on the surface of the cover 39 facing the opening to connect the end portion 36b and the cover 39 together.
Further, the operating arm 36 is supported by the arm supporting portion 43 so as to be spaced apart from the bottom of the cover 39 and to move the operating arm 36 . Thereby, the operating arm 36 can move with the arm supporting portion 43 as a fulcrum.
Further, when the detection bar 32 contacts the vehicle C, the detection bar 32 is displaced with the support member 31 as a fulcrum. Then, the end portion 36a of the actuating arm 36 is displaced in the direction in which the detection bar 32 is displaced, and the end portion 36b is displaced in the direction opposite to the movement of the end portion 36a. It can be displaced in conjunction with the detection bar 32 .

The cover 39 has a detection switch 38 on the top of the end 36b. The detection switch 38 is, for example, a reflective photoelectric sensor, and has a function of detecting movement of the operating arm 36 . When the end portion 36b moves away from the main body as shown in FIG. 6, the detection switch 38 can detect that the actuating arm has moved.
Although the detection switch 38 is a reflective photoelectric sensor, it is not limited to this, and a rolling switch or the like may be used. In addition, a configuration that detects the movement of the operating arm, such as by providing a switch or the like for detecting contact with both ends 36b of the operating arm, may be employed.

FIG. 7 is a block diagram for explaining the control system of the vehicle processing system according to the present invention.
A control board 50 incorporated in the main body 11 includes brushes 21 and 22 for washing the vehicle C, blower nozzles 23 and 24 for drying the vehicle C, a vehicle shape detection device 19 for detecting the vehicle shape of the vehicle C, a running encoder 18, and a running encoder 18. A motor 13 and a vehicle detection device 30 are connected.
The control board 50 operates the brushes 21, 22, blower nozzles 23, 24, etc. based on the information regarding the position, shape, equipment, etc. of the vehicle C obtained from the vehicle shape detection device 19 and the running encoder 18, and determines the position and shape of the vehicle. , equipment, etc. Also, based on a signal from the vehicle detection device 30, the main body 11 is stopped.

The vehicle detection device 30 can send a signal to the control unit 50 when detecting contact with the vehicle C. FIG. More specifically, when the vehicle C contacts the detection bar 32, the detection bar 32 is displaced with the support member 31 as a fulcrum. Then, the end portion 36a interlocking with the detection bar 32 moves in the direction in which the detection bar 32 is displaced, and the end portion 36b is displaced in the direction opposite to the end portion 36a.
Also, the detection switch 38 detects that the end portion 36b has moved. Thereby, the vehicle detection device 30 detects contact with the vehicle C and sends a signal to the control board 50 . Then, the control board 50 stops the main unit 11 .

FIG. 8 is an enlarged perspective view of a part of the vehicle detection device 30 of FIG. 9 is a top view of the vehicle detection device 30 of FIG. 1. FIG. A dashed line in the drawing indicates a state in which the vehicle detection device 30 detects a vehicle.
The vehicle detection device 30 has a flap 40 . The flap 40 is an elastic member (for example, rubber) and is provided at an angle so as to cover a portion of the operating arm 36 from one piece of the cover 39 . Further, the flap 40 has a cutout portion 41 on one side thereof in contact with the operating arm 36 . The cutout portion 41 is formed, for example, in a concave shape, and is provided so that the operating arm 36 is hooked on the cutout portion 41 . Therefore, the flap 40 has a function of suppressing displacement of the operating arm 36 when the operating arm 36 is fitted in the notch 41 .
Since the flap 40 is a member having elasticity, when the operating arm 36 slightly moves, the flap 40 bends to absorb and suppress the displacement of the operating arm 36 fitted in the notch 41 . Therefore, it is possible to suppress the displacement of the operating arm 36 due to strong wind, blowing air from the blowers 23 and 24, vibration when the main body 11 moves, and the like.
Further, the flap 40 is angled with respect to the actuating arm 36 during the angled engagement with the actuating arm 36 . By slanting the flap 40, it is possible to suppress slight movement of the operating arm 36 due to wind or the like, and to release suppression of the operating arm 36 at the time of contact with the vehicle C or the like.

When the detection bar 32 contacts the vehicle C, the detection bar 32 moves with the support member 31 as a fulcrum. Then, the actuating arm 36 linked with the detection bar 32 is displaced. At this time, the operating arm 36 is displaced, for example, toward the main body 11 side. At this time, the force displacing the operating arm 36 is stronger than the strong wind, blowing air from the blowers 23 and 24, and vibration when the main body 11 moves, so the flap 40 is released.
Thus, the flap 40 has the function of a limiter that suppresses constant vibration of the actuating arm 36 .

Moreover, since the detection bar 32 passing through the loop of the belt 37 has a gap between the belts 37, it is easy to swing in small increments. Therefore, the operating arm 36 interlocked with the detection bar 32 also slightly moves, but the provision of the flap 40 can suppress the fine movement of the operating arm 36 .

By providing the flap 40 in this way, it is possible to prevent the vehicle detection device 30 from malfunctioning due to strong winds, blowing air from the blowers 23 and 24, vibration when the main body 11 moves, and the like.

The vehicle detection device 30 is provided forwardly of the main body 11 and spaced inwardly of the inner surface of the leg 12 by a holding portion including a support member 31 and an operating arm 36, and detects the vehicle before the vehicle C contacts the main body 11. can be detected.
Further, by providing the detection bar 32 extending in the vertical direction, the detection range of the vehicle detection device 30 can be the entire height direction of the leg 12 .
Further, the vehicle detection device 30 is configured such that the upper portion of the detection bar 32 is supported by the support member 31, and the lower portion of the detection bar 32 is interlocked with the operating arm 36. 36 are interlocked, and the vehicle detection device 30 can detect the contact of the vehicle C. FIG.
By providing the flap 40 , the vehicle detection device 30 can suppress constant vibration of the operating arm 36 .

In this description, the vehicle detection device 30 is configured on the front side of the main body 11. However, there is no limitation on the arrangement, such as providing on the rear side of the main body 11 or providing in both directions. .
Also, the type and arrangement of the vehicle processing device 10 are not limited to the configuration described herein.
Furthermore, in this description, the vehicle detection device 30 and the side mirror of the vehicle C are described as being in contact with each other, but the contact is not limited to this, and an obstacle such as an object may be assumed. In addition, when the vehicle C stops at an oblique stop position, the vehicle detection device 30 can also detect the corners and sides of the vehicle C. As shown in FIG.
In this description, the support bar 42 for supporting the cover 39 is described as a bar, but the support bar 42 is not limited to this.
Further, although it has been explained that the support bar 42 is provided with the operating bar 36 and the switch 38, it is not limited to this. A vehicle stop position device such as a car may be installed together.
Furthermore, not only a vehicle stop position device such as Japanese Patent Publication No. 6684150, but also a device for detecting that the vehicle C is entering the main body 11, the vehicle processing device 10 can detect that the vehicle detection device 30 The main body 11 may be controlled according to the movable state of the vehicle C and the main body 11 when it is detected.

The vehicle detection device 30 can also prevent a collision between a wall and a vehicle by providing it in a partitioned place such as a wall, for example, in a passage such as an entrance of a parking lot. When used in a parking lot or the like, for example, a configuration may be adopted in which a warning light is turned on by a signal output from a detection switch.

In this manner, the vehicle detection device according to the present invention can be used in various applications other than the car washing device.
