JPH01160761A - Method for washing vehicle in arched car washer - Google Patents

Abstract

PURPOSE:To make it possible to wash a vehicle body in a one-way travel with no unwashed part being left, by rotating side brushes in an arched car washer in a predetermined direction so as to wash one-half of the vehicle body, and by reversing the side brushes at the center of the vehicle body so as to wash the remainder half of the vehicle body. CONSTITUTION:Side brushes 3 in an arched car washer arranged movably along an automobile stopped in place are rotated in a predetermined (counterclockwise) direction so as to move the side brushes 3 from the left to the right, relative to the vehicle body of the automobile so as to wash the front half of the vehicle body. The side brushes are reversed at the center position of the vehicle body and are further moved rightward so as to wash the rear half of the vehicle body. With this arrangement, it is possible to sufficiently wash the vehicle body in a one-way travel with no unwashed part being left in raised parts such as a front window, a rear window, a fender mirror and the like.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a car washing method using a gate-type car wash machine, which washes a car by running the brush astride the car while rotating the brush.

[Conventional technology]

Figures 3 and 4 show a general gate-type car wash machine (1), which includes a top brush (2) for washing the top surface of a car;
Side brushes (3) (3) for cleaning both side surfaces and rocker brushes (4) (4') for cleaning the lower portions of both sides are provided.

Fig. 5 (In this figure, only one side brush (3) is shown, and the other brushes (2) and (4) are omitted)
As shown in the figure, the car (5) has a fender mirror (6).
) or a protruding object such as a door mirror (not shown).
These brushes are made to have high strength against loads from the front, so the rotation direction of the top brush (2) and side brushes (3) should be set so that the cleaning system hits the protruding object from the front. is in the direction of the arrow shown.

Conventionally, the car wash machine (1) is run on its own to wash the car without changing the rotation direction of each brush (2), (3), and (4).

[Problem that the invention seeks to solve]

The front window (7) and rear window (8) of the automobile (5) are generally curved so that the center protrudes forward and backward when viewed from above, so the top brush (2)
Both left and right ends (7a) (7) of both windows (7) (8)
a) (8a) The contact of the washed hair to (8a) is weak,
The cleaning power is weak, but the both ends of the front window (7) (
7a) The lack of cleaning in (7a) is compensated for by cleaning by the side brush (3) which rotates in the direction of the arrow in Fig. 5.

However, in the conventional cleaning method, since the direction of rotation of the side brush (3) remains unchanged,
) (8a) is a side brush (8a) as shown in Figure 5.
The cleaning bristles of 3) are pressed by the side windows (9) and are greatly curved, causing the cleaning bristles (8a) (
8a) Since it escapes more, it cannot be washed.

In order to prevent this residue from being washed, generally the cleaning bristles at both ends of the top brush (2) should be made longer. The contact with the flat surface becomes weaker, and the cleaning power in this area decreases.

[Means for solving problems]

The present invention aims to solve the above-mentioned problem by reversing the direction of rotation of the brush when the brush reaches a suitable intermediate position of the automobile, thereby preventing unwashed parts.

[For production]

According to the method of the present invention, when washing a car that has a rising part in the center, such as a passenger car, the rotation direction of the first brush is set in advance in a direction that makes it easier to wash the front face of the rising part. After that, the brush is reversed at a suitable intermediate position of the rising portion, and the rear surface of the rising wall can then be cleaned with the same cleaning effect as when cleaning the front surface.

Therefore, the car can be washed without any leftover residue by just one one-way trip of the car wash machine.

〔Example〕

1 and 2 show the method of the present invention.
As in the figure, only one side brush (3) is shown.

In the present invention, the upper surface and lower side of the automobile (5) are
Similar to the conventional method, the top brush (2) and rocker brush (4) are cleaned without changing their rotational directions.

As shown in Fig. 1, when the side brush (3) cleans the front half of the car (5) and reaches approximately halfway between the front window (7) and the rear window (8), Temporarily stop running the car wash machine (1) and close the side brush (3).
) is moved slightly outward and the direction of rotation is reversed, and then brought close to the car (5) again and the car wash machine (1)
The remaining parts are washed by running the machine.

The negative stop position of the car wash machine (1) is best if the side brush (3) is between the windows (7) and (8), and there is enough room around 1, so for example, the front side of the car wash machine (1) The front end of the car (1) can be detected by the ultrasonic sensor (10) installed in the center of the upper part, the photoelectric sensor (11) installed in both legs, the swinging of the side brush (3), etc. (2), the front window (7) is detected, the timer is activated at the same time as the detection, and the position reached by the car wash machine until the set time of the timer elapses is the temporary stop position and the side brush (3). ) as the reverse position,
Alternatively, attach the ultrasonic sensor (10), photoelectric sensor (11), etc. to the car wash machine (1) at an appropriate distance in front of the side brush (3) (see Figure 4), and The side brush (3) may be reversed at the same time that the sensor (10) (11) detects the rear end surface of the vehicle (5) or the rear window (8).

Although not shown, the position of the car (5) during a car wash is usually approximately constant, so if there is a wall between the car wash machine (1) and the floor, or on the side of the car wash machine (1), is a car wash machine (1
) and the wall, and install appropriate sensors to ensure that the car wash machine (1) -
The vehicle may be stopped when the vehicle travels to the stop position. In addition, although the above-mentioned Example is a case where this invention is applied to a side brush (3), it can also be applied to a top brush (2), a rocker brush (4), etc.

〔Effect of the invention〕

According to the method of the present invention, when the rotating brush is used to clean the area around the upright part of a car, the initial rotational direction of the rotating brush is determined in advance in a direction in which the cleaning bristles of the brush are likely to come into contact with the front surface of the upright part. By doing so, the direction of rotation of the brush will be reversed during the car wash.

The rear surface of the rising portion can be cleaned in the same manner as the front surface.

Therefore, even if the car wash machine runs only once in one direction, the front and rear corners of the rising part of the car will not be left unwashed, and the car can be washed more effectively.
