2. Description of the Related Art Conventionally, a guide arm is provided on a portal-type traveling frame which can travel in the front-rear direction of a vehicle so as to be capable of swinging in a horizontal direction, and a movable support frame provided on the guide arm and movable in the left-right direction of the vehicle. A cleaning brush suspended so as to be rotatable on the movable support frame, a spring for holding the guide arm at a neutral position orthogonal to the front-rear direction of the vehicle, and the guide arm swinging by a predetermined angle from the neutral position. And a deflection angle detection device for detecting that the guide arm has swung from the neutral position by a predetermined angle due to the cleaning brush contacting the front of the vehicle as the portal traveling frame travels. Is detected, there is known a car wash apparatus in which the running of the portal-type running frame is temporarily stopped, and the movement of the washing brush is controlled to wash the front of the vehicle (Japanese Utility Model Publication No. 55-35246). See broadcast).

[0003]

However, in the car washing apparatus, the movable support frame is stopped at the free end side of the guide arm, and the traveling of the portal-type traveling frame is started with the cleaning brush being driven to rotate. If the starting speed exceeds a predetermined value when washing the car, the guide arm is moved by the inertia force of heavy equipment such as the movable support frame, the washing brush, and the motor for driving the washing brush. The run-out angle detection device operates unnecessarily due to the large run-out in the direction opposite to the traveling direction of the die-type run frame, and the car wash device may malfunction due to this. The first problem is that the speed cannot be increased beyond the predetermined value, and as a result, the car washing time cannot be reduced.

Further, in the car washing apparatus, when the movable frame is stopped at the free end side of the guide arm and the cleaning brush is driven to rotate to start the traveling of the portal-type traveling frame, as described above, When the guide arm swings in the direction opposite to the traveling direction of the gate-shaped traveling frame due to the inertia force, it becomes oscillating vibration and the time required for its damping becomes longer, so the vehicle is moved ahead of the cleaning brush. As described above, when the cleaning brush is moved outward to wash the front of the vehicle based on the detection signal of the detecting means for detecting the front end of the vehicle, the guide arm is opposite to the traveling direction of the portal traveling frame as described above. The timing of swinging in the direction and the timing of moving the cleaning brush outward may coincide, and in such a case, the cleaning brush is separated from the front end of the vehicle, and the cleaning effect on the front of the vehicle is reduced. There was a second challenge of that.

In view of the above, it is an object of the first invention to solve the first problem by preventing the deflection angle detecting means from malfunctioning when the traveling frame starts traveling. Is to do.

In view of the above, it is an object of the second invention to solve the second problem by suppressing vibration of the guide rail caused by acceleration and deceleration of the traveling frame.

Next, the operation of this embodiment will be described mainly with reference to FIGS.

[0027] As shown in FIG. 5A, when the traveling frame 1 is at the standby position, a pair of side brushes SB,
SB is at the open limit position (a).

[0028] Here, when a start switch (not shown) is pressed, the pair of side brushes SB, SB
The motor is driven to rotate forward and the torque motors 15, 15 are driven in the closing movement direction. When the side brushes SB, SB are in the closed position (B) and the closed switches 24, 24 are activated,
The traveling frame 1 starts traveling at high speed (see FIG. 5, (a)).

At this time, the guide rails 7, 7
In the direction opposite to the forward traveling direction of the traveling frame 1 due to the inertia forces of the carts 8, 8, the side brushes SB, SB, the rotary motors 14, 14, and the torque motors 15, 15, which are supported near their free ends (FIGS. 3, 5). , although attempts Fureyo in the direction of the arrow B), the buffer stopper function of the pair of hourglass elastic rubber 17 _1, 17 _2, absorbs most of its inertial force, the deflection of the guide rail 7, 7 And the swing width can be kept small, whereby the small-angle switches 19,
19 can be prevented from malfunctioning. The shake This small, converges in a short time by the attenuation action of the drum-type elastic rubber 17 ₁ 17 _2.

The forward traveling of the traveling frame 1 at a high speed
When the photoelectric sensor 28 detects the front surface of the vehicle V, the traveling distance LA at that time is stored in the control device 32 (see FIG. 5B).

[0031] The continuing往走row of traveling frame 1, come to the traveling position L _1, the traveling speed is in the medium speed from a high speed (see FIG. 5 (c)). In this case, the traveling position L
₁ indicates that the side brushes SB and SB contact the front surface of the vehicle V when the traveling frame 1 is traveling at high speed, even if the distance between the front wheels and the front end is the largest among the vehicles that can be washed. The position is set in advance as a position where the small angle switches 19, 19 do not operate.

[0032] When the traveling position L becomes equal to the traveling position LA plus a predetermined distance X, ie, L ₂ = LA + X, due to the continuation of the traveling traveling at the intermediate speed of the traveling frame 1, the traveling speed of the traveling frame 1 is reduced from the intermediate speed to the low speed. a pair of side brushes SB, the forward rotation of the SB is stopped with, start operation of the timer T ₁ (see FIG. 5 (d)).

Here, the predetermined distance X is equal to the side brush SB,
The distance SB is set in advance so that the front rotation of the vehicle V can be cleaned by the forward rotation.

[0034] When the timer T ₁ is the time is up, a pair of side brushes SB, with SB is driven reversely rotated, the torque motor 9, 9 is driven in the opening direction of movement (Fig. 5, see (e)).

As described above, the front surface of the vehicle V is cleaned before the side brushes SB, SB come into contact with the front surface of the vehicle V and reach the limit position. During this washing, the guide rails 7 and 17 ₂ are vibrated by the pair of drum-shaped elastic rubbers 17 ₁ and 17 ₂ .
Since the vibration of the vehicle 7 is prevented, the front surface of the vehicle V can be efficiently cleaned.

When the side brushes SB, SB are in the open movement, the traveling frame 1 continues to travel at low speed.
As the SB moves open, the guide rails 7, 7
It swings in the direction opposite to the forward traveling of the traveling frame 1 (the direction of the arrow B in FIG. 3).

The operation of the small angle switches 19, 19 is confirmed until the timer T ₁ times out.
By operating the small angle switches 19, 19, the traveling frame 1
Is stopped, the side brushes SB, SB are driven to rotate in the reverse direction, and the torque motors 9, 9 are driven in the opening movement direction. This prevents the surface pressure of the side brushes SB, SB from becoming excessive when the photoelectric sensor 28 detects the front end of the vehicle V after a predetermined distance from the front end of the vehicle in a case where the front end is low. Can be.

[0038] When the side brushes SB, SB are in the open limit position, the traveling speed of the traveling frame 1 is changed from low speed to high speed (when the small-angle switches 19, 19 are operated, from stop to high speed), and the pair of side brushes SB, SB are mounted on the vehicle. A voltage in the closing movement direction is applied to the torque motors 15 and 15 so that a surface pressure suitable for cleaning both side surfaces of the V is obtained. Then, as the traveling frame 1 travels at high speed, both side surfaces of the vehicle V are washed by the side brushes SB, SB (FIG. 5, FIG.
(F)).

[0039] When the photoelectric sensor 28 detects the rear surface of the vehicle V as the traveling of the traveling frame 1 continues,
The running distance LB at that time is stored in the control device 32 (see FIG. 5, (g)).

[0040] By the continuation of the forward traveling of the traveling frame 1, the traveling position L is shifted by a predetermined distance Y to the traveling position LB.
When L ₃ = LB + Y, the forward traveling of the traveling frame 1 is stopped. The predetermined distance Y is determined by the side brush SB, after the photoelectric sensor 28 detects the rear surface of the vehicle V.
The distance SB is set in advance to a position suitable for cleaning the rear surface of the vehicle V (see FIG. 5, (h)).

[0041] When the closing movement of the side brushes SB, SB reaches the closing limit position, the reverse rotation of the side brushes SB, SB is stopped, and then they are driven forward and the torque motors 9, 9 are driven in the opening movement direction. Then, the traveling frame 1 is caused to travel backward at a low speed (see FIG. 6, (i)).
When the side brushes SB, SB open, the traveling frame 1 continues to move backward at a low speed. Therefore, depending on the shape of the rear surface of the vehicle V, the guide rails 7, 7, as the side brushes SB, SB open, move. condensate traveling in the opposite direction (Fig. 3 and 6, an arrow F direction) of but traveling frame 1 is swung, the hourglass elastic rubber 17 ₁ pair this runout, 17 ₂ by the buffer to receiving is to quickly guide rails 7, 7 can be returned to the neutral position.

When the side brushes SB, SB are in the open limit position, the traveling frame 1 starts high-speed reverse traveling, and the surface pressure of the side brushes SB, SB on the vehicle V is reduced.
Is applied to the torque motors 15 and 15 so that the surface pressure is suitable for cleaning the side surfaces of the motor. Thereby, both sides of the vehicle V are cleaned (see FIG. 6, (j)). When the side brushes SB, SB return at high speed and reach the front surface of the vehicle V while cleaning both side surfaces of the vehicle V, the side brushes SB, SB close. When the traveling frame 1 reaches the start position (see FIG. 5A), the traveling frame 1 is controlled to stop, and all the steps of cleaning the front, rear and both sides of the vehicle V are completed.

During the cleaning process by the side brushes SB, SB, the vertical movement of the top brush TB is controlled.
Although the upper surface of the vehicle V is cleaned, since these conventionally known cleaning means are employed, description thereof will be omitted.

Although the embodiments of the present invention have been described above, the present invention is not limited to the embodiments, and various embodiments are possible within the scope of the present invention. For example, in the above embodiment, the case where the present invention is applied to a car washer has been described.
Of course, the present invention can be applied to other surface treatment devices such as a surface polishing device for a vehicle, and a plurality of light emitters and light receivers of a photoelectric sensor for detecting an end surface of a vehicle are vertically arranged. Alternatively, when the mounting height is changed and the optical axes of the light emitter and the light receiver are arranged obliquely in the vertical direction so that the front surface of the vehicle can be detected, the small-angle switch can be omitted. Although a drum-shaped rubber is used as the elastic rubber, any other shape may be used as long as it has a desired function. Further, a single side brush device may be used instead of the pair of side brush devices.

[0045]

As described above, according to the first aspect of the present invention, when the traveling frame starts traveling, the guide rail supported by the traveling frame is supported by the processing apparatus. Due to the inertia force, the vibration in the direction opposite to the running direction of the running frame can be suppressed as small as possible by the cushioning function of the elastic rubber, and as a result, unnecessary operation of the swing detecting means can be prevented. Therefore, the traveling speed of the traveling frame can be set to be higher than that of the conventional one, whereby the surface treatment time of the vehicle can be shortened and the treatment efficiency can be greatly improved.

According to the second aspect of the present invention, the swing of the guide rail accompanying the acceleration and deceleration of the traveling frame can be converged in a short time by the cushioning and damping function of the elastic rubber. Since the surface treatment body supported by the guide rail can follow the vehicle end surface better, the surface treatment effect of the vehicle end surface can be improved as compared with the conventional one.
