Abstract

PURPOSE:To have even and efficient brush cleaning even in case there are projections and recesses on the front and rear surfaces of a car body by rotating vertical brushes either regularly or reversely, and moving it as creeping on the front or rear surface of the car body. CONSTITUTION:When vertical brushes 51, 52 are rotated regularly and moved as approaching each other until their bristles approach so as to interfere with each other approx. on the center line L-L of a vehicle V, a gate-form traveling frame 1 starts forward motion. When the two brushes 51, 52 come in slide contact with the front surface of the vehicle V body, this traveling frame 1 stops the forward motion. When the two brushes 51, 52 move in the direction apart from each other to reach the left and right ends of the front surface of the body, they move in the directions as approaching each other to perform brush cleaning of the front surface. When the close position is attained where the bristles interfere with one another, the brushes 51, 52 are rotated reversely and move in the direction of opening so as to perform another phase of brush cleaning on the front surface.

Description

DETAILED DESCRIPTION OF THE INVENTION A1 Object of the Invention (1) Field of Industrial Application The present invention relates to a car washing method for brushing the body surface of a vehicle such as an automobile, particularly the front or rear surface thereof.

(See Publication No. 9).

(3) Section to be solved by the invention However, in the conventional car washing method, a pair of vertical brushes is rotated in one direction to brush the front or rear side of the car body. When there is an uneven part on the rear surface, the bristles of the vertical brush B, which rotates in one direction, are directed toward one side (a) of the uneven part P, as shown in Fig. 4, and from the other side (b). There is a problem that the particles tend to escape, making it difficult to evenly brush the entire area of the uneven portion.

The present invention has been made in view of the above-mentioned circumstances, and it controls the forward and reverse rotation of the vertical brush, and controls the movement of the vertical brush along the front or rear surface of the vehicle body. To provide a car washing method with a simple structure, which enables evenly and efficiently brushing the rear surface even if the rear surface has uneven parts.

B1 Structure of the Invention (1) Means for Solving the Problems According to the present invention, in order to achieve the above-mentioned object, a pair of motors, which are controlled to rotate in the forward and reverse directions around the vertical axis and to move back and forth in the left-right direction of the vehicle, are provided. In a car washing method in which a vertical brush is used to brush the front or rear surface of a vehicle body, the pair of vertical brushes are rotated in either a forward or reverse direction and separated from each other along the front or rear surface of the vehicle body; Alternatively, the front or rear surface of the vehicle body may be brushed and cleaned by moving the brushes toward each other, and then the pair of vertical brushes may be rotated in the opposite direction to the previous step, and the brushes may be moved away from or close to each other along the front or rear surface of the vehicle body. Clean the front or rear of the vehicle by brushing the front or rear of the vehicle.

(2) Effect According to the above configuration, by controlling the pair of vertical brushes in forward and reverse rotation and controlling their movement along the front or rear surface of the vehicle body, uneven portions can be formed on the front or rear surface of the vehicle body. In some cases, the front surface can be evenly and thoroughly cleaned by brushing.

(3) Examples An embodiment of the present invention will be described below with reference to the drawings.

The horizontal brush 4 has a horizontal shaft 6 horizontally mounted on the same type traveling frame 1.
It is supported so as to be able to swing vertically via a swinging arm 7, and is rotationally driven by a motor 8 provided on the swinging arm 7 via a transmission mechanism within the swinging arm 7. The horizontal brush 4 is controlled to rise and fall together with the swing arm 7 via a lift mechanism (not shown).

A pair of first and second vertical brushes 51.5° are suspended from the rear part of the concave traveling frame 1. That is, the pair of movable frames 10 are engaged with the guide rails 9 horizontally suspended on the concave traveling frame 1 so that they can reciprocate in a direction perpendicular to the traveling direction of the gate-shaped traveling frame 10, that is, in the left-right direction of the vehicle to be washed. A vertical shaft 11 on which each vertical brush 56, 5□ is suspended is suspended from the moving frame 10, and each moving frame 10 and vertical shaft 11 are connected to each other with the support shaft 12 of the guide rail 9 as a fulcrum. It can swing in the running direction of the mold running frame 1. A prime mover 13 is supported on each moving frame 10, and the prime mover 13 can rotationally drive each vertical brush 5z via a transmission mechanism. Both vertical brushes 53, 5□ are guide rails 9
open so that they are spaced apart from each other or close to each other along the
Alternatively, the closing movement is controlled, and a conventionally known movement control device is used. The double-sided vertical brushes 51 and 52 have string-like bristles embedded in the core material, so when each of the vertical brushes 58 and 52 is not rotating, all the bristles hang down and the brush diameter becomes small. (The vertical brushes 5I, 52 are shown in a rotating state in FIG. 2).

The front part of the concave traveling frame 1 is equipped with a drying device. That is, a pair of side air blowing nozzles 14 that open inward are provided on both sides of the gate-shaped traveling frame 10, and a top air blowing nozzle 15 that also opens inward is provided on the upper surface of the frame so as to be movable up and down.

(2) Vehicle body front cleaning process (A) process: The vehicle (2) to be cleaned is stopped at a predetermined position between a pair of running rails 2. The concave traveling frame 1 is at the left end position, and both the mold surface brushes 50, 5□ are stopped at the open position and spaced apart from each other.

(B) Process: When the operating switch 18 (Fig. 1) is closed, both vertical brushes 5
I, 5□ rotates forward (counterclockwise), and both brushes 51, 5° move in the closing direction, that is, toward each other (in the direction), and their bristles align with the approximate longitudinal centerline L- of the vehicle. They approach each other until they interfere with each other on the L line.

(C) Process: When the concave traveling frame 1 starts moving rightward and both vertical brushes 5+ and 5z come into sliding contact with the front of the vehicle body, the gate-shaped traveling frame 1 stops moving forward.

After a predetermined period of time has elapsed, both vertical brushes 51.5□ continue to rotate in the normal direction while slidingly contacting the front surface of the vehicle body and moving in the opening direction, that is, in the direction of separating from each other. At this time, both vertical brushes 59,
Brushing cleaning of the front of the vehicle body is performed by 5□. Then, both vertical brushes 51 and 52 move to both left and right ends of the front of the vehicle body.

(D) Process: When the vertical brushes 58, 5□ reach both left and right ends of the front of the vehicle, they move along the front of the vehicle in the closing direction, that is, in the direction of approaching each other, while continuing to rotate in the forward direction. Brushing cleaning is performed by forward rotation of the front vertical brushes 55,52.

Step 1 (E): When both vertical brushes 51 and 52 move in the closing direction to the vicinity of the longitudinal center line LL of the vehicle V and reach the closed position where their bristles interfere with each other, both vertical brushes 51 and 5□ are moved. back reverse(
(clockwise rotation) control.

After a predetermined period of time has elapsed, both vertical brushes 50.5□ continue to rotate in reverse while slidingly contacting the front surface of the vehicle body and moving in a direction in which they are separated from each other, that is, in an opening direction. At this time, both vertical brushes 51, 5
Brushing cleaning of the front of the vehicle body is performed by rotating in the opposite direction.

Through the above steps (C) to (E), the front surface of the vehicle body is uniformly brushed and cleaned by forward and reverse rotation of the pair of vertical brushes 51.5□. Therefore, for example, even if there is an uneven portion on the front surface of the vehicle body, the front surface can be evenly brushed and cleaned.

■ Washing process (F) on both sides of the vehicle body: 0 The movement of the pair of vertical brushes 54, 54, is temporarily stopped at the maximum open position of 5°, and the concave traveling frame 1 is allowed to move in the right direction again. Start. Also, a pair of vertical brushes 51. , ) Due to the movement of z in the closing direction, they continue to rotate in the opposite direction! It comes into sliding contact with the front side of the vehicle body, and brushing cleaning of both sides of the vehicle body begins.

(C) Process: A pair of vertical brushes 5 are created as the gate-shaped traveling frame 1 continues to move back and forth.
