Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a support device for a side cleaning brush in a vehicle cleaning device.

(Prior art) The side cleaning brush, which is supported by the running frame and rotates once while following the car body surface, is rotated in a direction perpendicular to the running direction of the running frame in order to clean the front, rear and side surfaces of the car body. Must be movable. Conventionally, for this purpose, the swing arm method uses a swing arm that supports the rotating side cleaning brush vertically and moves it horizontally, and the tip of the side cleaning brush supporting arm, which has a bendable middle part, is moved inward from both sides of the inside of the running frame. A device (Japanese Unexamined Patent Publication No. 158071/1983) has been put into practice that uses a pair of guide arms extending in the opposite direction.

(Problems to be Solved by the Invention) The above-mentioned swing arm type requires a large member to be used for the swing arm in order to increase the radius of curvature of the trajectory of the side brush. , and there is a large difference between the trajectory of the swing arm and the shape of the front and rear surfaces of the vehicle.
There is a problem in that it is difficult to maintain uniform contact pressure.

In the case of a system in which a bendable brush support arm is guided by a guide arm, the guide arm swings in order to detect the contact pressure between the side cleaning brush and the front and rear surfaces of the vehicle and control the traveling frame. Therefore, it is necessary to have two guide arms that are swingably supported on both the left and right sides of the traveling frame, and the long guide arm must have a support member or a stopper device in the center to support it. The component parts are large and the structure is complicated, and the 5A position ff [
There was a problem that the amount of noise was large and the cost was high.

The present invention has been made to solve the above problems,
The side cleaning brush moves linearly in a direction perpendicular to the traveling direction of the traveling frame, and provides a side cleaning brush support that is simple in structure, lightweight, and inexpensive. The purpose is to [ ].

[Means for solving problems]

The proximal end of a side cleaning brush support arm, which is composed of a pair of proximal end arms and a distal end arm and whose intermediate part can be freely bent, is pivoted to the traveling frame so as to be able to swing freely in the horizontal direction. An air cylinder for opening and closing the side cleaning brush support arm is attached between the arms, the side cleaning brush is rotatably supported in the vertical direction by the tip arm, and an actuator for displacement detection is provided in the center of the tip arm. It is guided by a horizontally stretched cable under tension by a spring and biased toward the center by the appendix.

[For production]

The side cleaning brush is supported by a side cleaning brush support arm whose middle part can be bent freely, and is guided by a horizontally stretched cable to move on the traveling frame in a direction perpendicular to the traveling direction of the traveling frame. Further, the contact pressure between the side cleaning brush and the front and rear surfaces of the vehicle body is detected by the displacement of the cable, and four types of control of the travel of the traveling cup can be performed.

【Example〕

An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, a pair of side E brush support arms 19 and 19' are pivotally fixed to a traveling frame 1 capable of reciprocating on a pair of traveling rails is and ia' so as to be able to swing in the horizontal direction.
proximal arms 3.3' which are flexibly connected to each other;
and a tip arm 4.4', which is vertically connected to a side cleaning brush 2.2'.
A bearing device 20.20' is used to support the.

The lateral brush 2.2' supported on the bearing arrangement 20, 20' is driven by a motor 5, 5' mounted on the underside of the end arm 4.4' through a chain and a sprocket (not shown). Driven in U rotation. A guide carriage 6.6' is rotatably supported on the upper surface of the tip arm 4.4' coaxially with the side cleaning brush 2.2'.

Each of the guide carriages 6,6' has four trochanters on its right side, through which a cable 11 is stretched between pulleys io, io' supported on both sides of the running frame 1. ing. Both ends of the cable 11 receive the elasticity of springs 12, 12' that abut against spring seats fixed to the traveling frame 1, and a predetermined tension is applied to the cable 11.

The rod 8 fastened to the center of the cable 11 is connected to the running frame 1
Due to the action of the spring seat 14 and the spring 9.9' fixed to the
The cable 11 is supported in a neutral position. The forward and backward displacements of the cables 11 in the running direction of the running frame 1 are controlled by proximity switches 16 and 16' (the proximity switch 16' is not shown) by the action of actuators 15 and 15' fixed to the bolts 8, respectively. ) is detected.

Side cleaning brush support arm 19.19' proximal arm 3.
3' and the air cylinder 7 provided between the support frame 1.
When compressed air is supplied to 7', the side cleaning brush support arm 1
9.19' is guided by the cable 11, and when the air in the air cylinder is exhausted, the guide carriage 6
．． By the action of ff 113° 13' suspended from 6' via pulleys 17 and 17', the side cleaning brush support arms swing inward to close. A top cleaning brush for cleaning the top of the vehicle is supported in a conventional manner, but is not shown.

This example has the composition as described above, and its function will be explained next.

Vehicle 21 stopped in front of traveling frame 1 in FIG.
The traveling frame 1 moves from the position shown in Fig. 2 (a) in the direction shown in Fig. 2 (b).
, (C) and (d) sequentially by 1J. During this time, the side cleaning brush rotates, and cleaning water is supplied from a nozzle (not shown) to perform cleaning in the forward stroke. In this stroke, the air in the air cylinders 7°7' is initially exhausted, but the side cleaning brushes 2.2' are pushed by the vehicle 21, and the cables 11 are removed as shown in Fig. 2(b). When displaced backward, the traveling frame 1 is stopped by the action of the proximity switch 16', and compressed air is supplied to the air cylinder 7.7'.
The side cleaning brush opens to the position shown in FIG. 2(C), during which time the front of the vehicle is cleaned. When the side cleaning brush opens to its maximum extent, this is detected by a limit switch (not shown), and the air in the air cylinders 7, 7' is exhausted and the traveling frame 1 is made to travel again. At this time, the appendix 13.
13', the side cleaning brushes 2, 2' are pressed against the side surface of the workpiece and are moved together with the traveling frame 1 as shown in FIG. 2(d).
The side of the vehicle is cleaned by moving to the position shown in . When the running tE frame 1 reaches the position shown in FIG. 2(d), the side cleaning brush moves to the center and the rear m1 of the 11 cars is cleaned.

The above is the cleaning operation in the forward stroke of the traveling frame 1, but in the backward stroke, the traveling frame 1 is cleaned as shown in (d) in FIG.
, (e), (f), (g), and (h) in the same way as in the outgoing stroke 1'J.

However, in the backward stroke, it is the proximity switch 16 that detects the contact pressure between the side cleaning brush 2.2' and the vehicle body 21, and at the end of the cleaning stroke, the side brush 2.2' moves to the open position.

〔Effect of the invention〕

Since the guide that guides the side cleaning brush in a straight line is made of cables, displacement in the horizontal direction can be easily detected by a pair of detection means. It can be constructed using pumice at a low cost.

Further, since the contact pressure between the side cleaning brush and the vehicle body is detected by the elastic deformation of the cable, the detection accuracy is high and reliable.
