Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a novel structure of a roll brush used, for example, for polishing and cleaning the surface of a rolled steel plate.

[0002]

2. Description of the Related Art There are two typical types of conventional roll brushes as described below. (A) Channel type roll brush As shown in FIG. 5, the bristle bundle 52 is pushed into the groove of the metal long channel 51 while the wire rod 53 is pushed in the middle of the longitudinal direction of the bristle bundle 52 to be folded in two. Hair bundle 5
2 makes a long channel-shaped brush 50 that is planted over the entire length of the channel.
As shown in FIG. 6, the roll 70 is tightly spirally wound around the roll 70, and both ends thereof are fixed to the roll 70 by appropriate means. (B) Disc type roll brush As shown in FIGS. 7 and 8, a circular arc slit 61 is provided in the peripheral portion at a predetermined interval, and a disc 63 having a shaft groove 62 with a key groove at the center is formed. , Hair bundle 6 in each slit 61
4 are inserted and folded in two, and the hair bundles 64 radially protruding around the outer periphery of the disc 63 are bundled and fixed by the wire rod 65, so that the positions of the key grooves are offset by 90 degrees from each other. The brushes 60A and 60B are manufactured, and a large number of each of them is alternately inserted into and laminated on a roll 71 as shown in FIG. 9, and both ends thereof are fastened and fixed.

[0003]

Problems to be Solved by the Invention (a) and (b)
As described below, the two types of roll brushes have advantages and disadvantages in terms of both function and manufacturing cost.
As can be easily understood from the structure, the channel type roll brush of (a) is excellent in productivity, but as shown exaggeratedly in FIG. 6, it is closely spirally wound and adjacent to the channel brush 50. , 50 between the long channels 51
It is unavoidable that a gap corresponding to twice the thickness of the steel sheet is generated, and for example, when it is used for polishing and cleaning a steel sheet, there is a possibility that brush marks (scratches) may occur. On the other hand, in the disc type roll brush of (b), as shown in FIG. 9, the bristles 64 are intermittently projected from the peripheral portion of the disc type roll brush 60A, 60B of one of the disc brushes 60A, 60B adjacent to each other. Hair bundle 6
Since the bristle bundle 64 of the other brush 60B is configured to bulge laterally to fill in the part where 4 is missing,
The above problem is solved. However, as is clear from the figure, there was a major drawback in that it took too much time to manufacture. Therefore, an object of the present invention is to provide roll brushes having the respective characteristics of the above-mentioned two types of roll brushes, eliminating the respective drawbacks, distributing the hair bundles evenly, and sufficiently enhancing the productivity. To provide.

[0004]

In order to achieve the above object, a roll brush according to the present invention has a predetermined interval over the entire length of one side edge of the long strip 2 in the longitudinal direction. Two
A strip-shaped brush B having a structure in which the folded bristles 3 are straddled so that the tip end side thereof projects from the other side edge, and this straddle state is fixed by a fixing means is spirally formed on the outer peripheral surface of the roll 1. The structure was tightly wound. The fixing means is a clip-shaped fixing tool for sandwiching a bristle bundle locking notch 2a provided at one side edge of the long strip 2 at a predetermined interval, and a straddling portion of the hair bundle 3. It is better to configure it with 4. or,
A fold 2b for facilitating the winding of the strip-shaped brush B may be provided over the entire length of the long strip 2.

[0005]

The strip-shaped brush B has a bristle bundle 3 that is folded in two and is protruded from the other side edge of the long strip plate 2 at predetermined intervals over the entire length of one side edge in the longitudinal direction. The product is continuously mass-produced by simply straddling it and fixing this straddle state by the fixing means. The band-shaped brush B is spirally densely wound around the outer peripheral surface of the roll 1 and both ends thereof are fixed by known means to complete the roll brush. Then, when the strip-shaped brush B is wound, the non-bristed portions of the adjacent strip-shaped brushes B, which are spirally wound, are buried by the bristles 3 of each other so that the entire surface of the roll brush is covered. The hair bundles 3 are evenly distributed. If the folds 2b are provided over the entire length of the long strip 2, the strip-shaped brush B can be easily placed on the roll 2 with the long strip 2 standing upright with respect to the outer peripheral surface of the roll 1. Can be wrapped.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. The roll brush A has a structure in which a belt-shaped brush B, which will be described in detail below, is tightly spirally wound around the outer peripheral surface of the roll 1, as shown in FIG.

As shown in FIG. 2, the belt-shaped brush B, the appearance of which is partially shown in FIG. 3, has one side edge in the longitudinal direction of the long strip 2 made of metal or synthetic resin which is easily plastically deformed. In each of the hair bundle locking notches 2a provided at predetermined intervals, the hair bundle 3
Is folded in two in a U shape and hooked, and the tip end side thereof is projected from the other side edge so that the tufts of hair 3 straddle the long strip 2 and this straddling point serves as a fixing means. It has a configuration in which it is sandwiched by clip-shaped fixtures 4. After being clamped, the fixing tool 4 is flattened and crushed as shown in the left side portion of FIG. 2 to play a role of fixing the hair bundle 3. In this embodiment, the hair bundle locking notch 2a is formed in the shape of a shallow groove having the same width as that of the hair bundle 3 so as to prevent lateral displacement of the hair bundle 3. As shown in FIG. 2, the fixture 4 has a shape in which one end side of a metal tube having a size slightly longer than the width of the long strip 2 is expanded into a trumpet shape so that the hair bundle 3 can be easily covered, Long strip 2
A slit 4a for fitting is provided in a cut shape from this one end side.

In this way, the strip-shaped brush B continuously produced by the automatic manufacturing machine is wound in the spiral axial direction on the roll 1 as described above, as shown in FIG. 1, in the axial direction of the roll. The roll brush A is configured such that adjacent strip-shaped brushes B, B are filled with the bristles 3 of one of the brushes so that the bristles of the other brush are not filled.
Becomes a state in which the hair bundles 3 are evenly distributed over the entire outer peripheral surface thereof. Then, the roll brush A is completed by fixing the winding start end and the winding end end of the belt-shaped brush B to the roll by known fixing means.

At the time of winding, if the outer diameter of the roll 1 is small or the width of the long strip 2 is too wide, winding becomes difficult. In such a case, for example, as shown in FIG. It is good to use a long strip 2A. This long strip 2A
Is provided with a fold 2b on the side edge which is the outer peripheral side when wound around the roll 1, and the outer peripheral side is extended as the roll is wound.

[0010]

As is apparent from the above description, the roll brush of the present invention has the advantages of the conventional two types of roll brushes, the channel type and the disc type, and the disadvantages of each are eliminated. Has been done. That is, a) Since the distribution of the hair bundle is extremely uniform over the entire outer peripheral surface of the roll, there is no possibility of causing brush marks (scratches). b) Since the productivity is sufficiently high, it can be provided at a lower cost.
