Abstract

PROBLEM TO BE SOLVED: To improve build up of running speed at running a running frame in the direction of carrying a vehicle by providing the running rails supporting a washing supporting means so that the terminal ends in the vehicle carrying direction are inclined to be lower than the beginning ends. SOLUTION: An automobile V is carried in, the front face of the automobile V is contacted with a side brush 24, and when the shake of the brush from a nearly vertical neutral position 241 to an inclined position 242 by a fixed angle is detected by a shake detecting switch 36, a running frame 10 begins outgoing running. At this outgoing running, because running rails 7 are downward inclined in the outgoing direction of the running frame 10, acceleration of the running frame 10 is enlarged, build up of the running speed is improved, and hence speed difference between the running frame 10 and the carried vehicle can be reduced. Hereby, after detection by the shake detecting means 36, increase of contact force of the side brush 24 with the vehicle body can be reduced.

[0003]

In the above-mentioned conventional vehicle body washing device, the traveling drive device is switched from the inactive state to the active state based on the detection of the displacement detecting means, and the traveling state has been stopped. The frame is caused to travel in the vehicle transport direction, and since the rising of the traveling speed at the time of traveling is poor, the traveling frame (washing body support means) and the transport vehicle remain in the transport frame for a while after the detection of the displacement detecting means. The speed difference remains large, and the speed difference causes the cleaning body to be pushed more and more against the vehicle end face. Therefore, when the traveling frame stopped based on the detection is caused to travel in the vehicle transport direction, there is a problem that the force with which the cleaning body contacts the vehicle body increases.

The present invention has been made in view of such circumstances, and based on the detection of the displacement detecting means, the cleaning body contacts the vehicle body when the stopped traveling frame travels in the vehicle transport direction. The purpose of the present invention is to reduce the force to be applied compared to the conventional device.

Possible cleaning body support means, a cleaning body rotatably supported by the cleaning body support means, and holding the cleaning body support means in the neutral position, wherein the cleaning body support means is displaced from the neutral position. Therefore, a neutral holding means for increasing the holding force and a displacement detecting means for detecting that the cleaning body supporting means has been displaced by a predetermined amount or more from the neutral position are provided. Controlling the traveling drive device to move the stopped traveling frame in the transport direction on the basis of the traveling frame, thereby cleaning a front end surface of the vehicle in the transport direction. The rail is provided so as to be inclined such that the end of the rail in the transport direction is lower than the start end, and the inclination causes the stopped traveling frame to travel in the transport direction based on the detection of the displacement detection unit.

In order to move the traveling frame 10 in the transport direction X of the vehicle V at α), power of a preset frequency is output from the inverter 60 to the traveling motor 12 and the traveling frame 10
Starts going forward (see FIG. 5A). At the time of traveling, the traveling rails 7 are inclined downward with respect to the traveling direction of the traveling frame 10.
0, the acceleration of the traveling speed increases, and the traveling frame 10 (therefore, the bogies 19, 19)
And the speed difference between the side brushes 24 and 24) and the transporting vehicle can be reduced, thereby increasing the neutral position holding force of the neutral holding means N after detection by the shake detecting means 36, ie, increasing the side brushes 24 and 24). It is possible to reduce an increase in the force with which the vehicle body 24 comes into contact with the vehicle body (that is, as compared with a conventional device in which the traveling rail is not inclined).

When a predetermined time elapses in anticipation of the time for the side brushes 24 and 24 to return to a substantially vertical position, the forward speed of the traveling frame 10 becomes substantially the same as the transport speed R ₁ of the slat conveyor 39. Electric power having a preset frequency is output from the inverter 60 to the traveling motor 12, and the torque motors 23 are operated so that the left and right carriages 19 are separated from each other.

Is operated (see FIG. 5C). After a lapse of a predetermined time, a voltage at which the rotation of the torque motor 23 stops due to a balance between the driving force of the torque motor 23 and the contact reaction force received when the side brush 24 cleans the side surface of the vehicle body with an appropriate contact force. The trolleys 19, 19 are applied to the torque motors 23, 23, respectively, and approach the side of the vehicle body (FIG. 5).
(D)). Thus, the side brushes 24, 24
When the vehicle comes into contact with the vehicle body side surface, the torque motors 23, 23 stop rotating with the appropriate contact force acting on the vehicle body side surface, whereby the side brushes 24, 24 apply an appropriate contact force to the vehicle body side surface of the vehicle V. (See FIG. 5E).

When the traveling frame 10 reaches the standby position and the standby position switch 37 detects this, the traveling motor 1
2 is deactivated and the traveling frame 10 stops. Thereafter the side brush 24 and 24 wrap the rear surface of the motor vehicle V, when this wraparound switch 32 is detected (see (f) in FIG. 5), so that the traveling frame 10 is forward stroke at a conveying speed R ₁ and substantially the same speed The traveling motor 12 is operated.
When the approach stop switches 31, 31 detect that the carts 19, 19 have reached the approach stop position, respectively, the rotary motors 26, 26 are deactivated and the side brushes 24, 2 are deactivated.
4 is stopped, the torque motors 23, 23 are operated so that the carts 19, 19 are separated from each other, and the traveling motor 12 is operated, so that the traveling frame 10 goes backward (see (g) of FIG. 5). reference).

When the corresponding limit switches 30, 30, respectively, detect that the right and left bogies 19, 19 have reached their respective extreme positions, the torque motors 23, 23 are disabled and the bogies 19, 19 are stopped. I do. In addition, traveling frame 1
When 0 reaches the standby position and the standby position switch 37 detects it, the traveling motor 12 is deactivated and the traveling frame 10 stops (see (h) in FIG. 5). Thus, the operation of the side brush device S ends.

It should be noted that the present invention is not limited to the above embodiments, and various embodiments can be made within the scope of the present invention. For example, in the above-described embodiment, a vehicle body cleaning device using a side brush as a cleaning body was described.However, the present invention uses a nonwoven fabric cleaning body in which a nonwoven fabric is attached to a rotating body instead of the side brush. The present invention can be applied to a vehicle body washing device.

[0028]

As described above, according to the present invention, the traveling rail supporting the washing body supporting means is provided so as to be inclined such that the end of the rail in the vehicle transport direction is lower than the starting end,
This inclination improves the rising of the traveling speed when the stopped traveling frame travels in the vehicle transport direction based on the detection of the displacement detection means. Therefore, the cleaning body after the detection by the displacement detection means is improved. The increase in the force of contacting the vehicle body can be reduced.
