Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a brush roller for automatic car wash equipment and the like.

[Conventional technology]

As is well known, an automatic car wash device has a brush roller, which is rotated in contact with the vehicle body, and the free ends of the bristles of the brush roller are brought into contact with the surface of the vehicle body, thereby removing dust from the surface of the vehicle body. It is designed to remove small pieces such as

The brush roller of the above-mentioned structure usually has a large number of bristles, and the length of the bristles is all the same, so that the length of the bristles is in one direction approximately perpendicular to the axial direction of the brush roller. Only the specks of dust will be removed.

Thus, in many cases, the above-mentioned constructions are not able to completely remove dust-like particles, so that these particles accumulate in front of said rollers, leaving unwashed surface areas on the vehicle body. It turns out.

Furthermore, a disadvantage of conventional brush rollers is that the bristles are usually attached in bundles to a retaining layer, which is tightly wound around a cylindrical body forming the support frame of the roller. .

Thus, if the retaining layer of the brush roller is in continuous contact with the surface of the cylinder, the attachment of the bristles will wear away, resulting in cutting and separation of the bristles.

Another problem is that the cleaning soap and water are conventionally discharged from the outside of the brush rollers, which means that they do not reach the base of the bristles where dust particles accumulate. This will occur as a natural result.

[Problem to be solved by the invention]

SUMMARY OF THE INVENTION Therefore, the main object of the present invention is to overcome the above-mentioned drawbacks, to easily remove dust and dirt-like particles from the surface of a car body to be cleaned, and to remove dust and dirt-like particles from the brush roller. We offer brush rollers that are designed to be irresistible.

Another object of the present invention is to provide a brush roller with a long service life because the bristle attachment eliminates wear of the contact area between the part and the retaining cylinder.

Furthermore, another object of the present invention is to provide a brush roller that is highly functional.

Another object of the present invention is to provide a brush roller that is easily manufactured using readily available parts and materials and that is economically competitive compared to other products. It is about providing.

[Means to solve the problem]

In order to achieve the above-mentioned main purpose, the brush roller of the automatic car wash device according to the present invention has a cylindrical body and has a large number of bristles on the side surface thereof, and at least a part of the bristles has a length of the above-mentioned length. a portion of the roller that is longer than the length of the bristles of the remainder of the roller and has longer bristles arranged in a cylindrical helical shape around the roller, and as the roller rotates; The bristles are characterized in that they are configured to generate an axial force component to remove debris such as dust from the vehicle body surface with which the bristles come into contact.

[Action and effect]

Therefore, the action of the axial force generated on the long bristles makes it possible to reliably remove particles, such as dust, even into the recesses of the vehicle body, for example.

〔Example〕

Referring to the accompanying drawings, the brush roller of the automatic car wash device according to the present invention has a cylindrical body (2) for the brush roller. Said brush roller has the general reference number (1)
is shown.

The cylindrical body (2) functions as a holding frame for the brush roller (1), and a number of bristles are attached to the side surface of the cylindrical body (2).

Said bristles are designated with reference number (10).

An advantage is to attach the bristles (10) to a bristle retaining layer (11) made of a visible material such as rubber or plastic.

The bristle-retaining layer (11) is roughly rectangular and has at its end a connecting means with corresponding pins (13) for attaching each layer around the cylinder (2). It consists of a hole (14).

It is clear that with regard to this coupling means, different layers can be used, depending on the axial length of the cylinder (2).

The bristles (10) are bundled into pairs or bundles, and
The attachments arranged on the surface of the layer (11) opposite to the side with the bristles (10) are attached by means (15) to this layer (1).
1).

This opposite surface has an edge (20) which acts as a spacer means and furthermore has a number of equally spaced space bins (21), thereby allowing the cylinder (2) to A small gap (22) is formed between the layer (11).

This gap (22) has two functions. The first function is that the attachment prevents the means (15) from being damaged by wear and tear, since the attachment prevents the means (15) from coming into direct contact with the cylindrical body (2); The function is to form a region through which cleaning substances and cleaning water are introduced from the inside to the outside of the brush roller (1) through the through hole (30) of the cylindrical body (2), and to uniformly distribute the cleaning liquid throughout the brush roller (1). The aim is to make it easier to spread the information across the board.

Furthermore, the main feature of the invention is the different lengths of the bristles (10). More precisely, the length of some bristles (IOa) is longer than the length of the remaining bristles shown in (10b). As illustrated by the dotted line (A) in FIG.
) are placed diagonally along the dotted line (8),
Moreover, it is advantageous that they are arranged in large numbers in the axial direction, and these longer bristles (10a) form a large number of cylindrical spiral patterns on the outer surface of the cylindrical roller. .

During the car washing operation, when the brush roller (1) rotates, an axial displacement component is exerted on these longer bristles (10a) arranged along a cylindrical spiral shape, causing the bristles (10
a) can easily remove dust-like debris from surfaces it comes into contact with;

Thus, during the cleaning operation, debris such as dust can be continuously removed from the vehicle body and the inconvenience of accumulation of dust debris, which can result from insufficient cleaning, can be avoided.

Furthermore, it is advantageous that the bristles (10) are not bundled at their free ends and have an unbound part, indicated by reference number (40). This non-bundling part (40) forms a relatively soft and free-moving bristle band, which prevents damage to the car body, and also widens the contact surface between the bristles (10) and the car body. There is a particular thing.

With the above disclosure, it is clear that the present invention is able to fully achieve its intended objectives.

In particular, the longer bristles (10a) along the cylindrical spiral shape
Due to the special arrangement of the bristles, when the brush roller (1) rotates, it generates an axial component of force, which makes it possible to effectively and easily remove debris such as dust from the car body. It is shown that a roller (1) is provided.

A further feature of the invention is that the bristle retaining structure forms a support frame for the brush roller (1) and has a gap (22) around the cylinder (2), which gap (22) is It is possible to introduce cleaning substances and cleaning water radially outwardly directly from said roller (1), whereby the attachment of the bristles (10) of the brush roller (1) makes it possible to thoroughly clean the part. be.

Moreover, this gap (22) prevents the attachment of the bundle of bristles (]0) from touching the cylinder (2), and thus prevents the bristles (10) from wearing out in a short period of time. do.

Various changes and modifications can be made to the disclosed invention within the spirit and scope of the claims.

Furthermore, all disclosed details can be replaced by other technically equivalent elements.

When carrying out the invention, the materials used, the type and the dimensions may vary depending on the requirements.
