DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a brush roll used for polishing the surface of an iron plate such as a rolled plate.

[0002]

2. Description of the Related Art Disc-type brush rolls and channel-type brush rolls are used as the above-mentioned brush rolls.

[0003] A disk-type brush roll forms a disk brush in which a number of brush bundles are implanted on an outer peripheral portion of a disk and a bristle tip is extended in a radial direction, and the disk brush is placed at the center of the disk. Insert a large number into the shaft with the provided shaft hole,
This is a brush roll formed by compressing and fastening the disk brushes in the axial direction.

On the other hand, the channel type brush roll is a brush roll formed by spirally contacting and winding a channel brush having a base portion of a brush material with a U-shaped metal band around a shaft.

[0005] As the above-mentioned brush material, a composite brush material in which a filament containing abrasive particles is used as a core material and a braided coating is applied to the core material with fine filaments is often used. This brush material is suitable as an iron plate polishing brush because it has both a polishing action by the core material and a wiping action by the coating material.

[0006] In addition, the braided coating of the above-mentioned composite brush material has the property of making the core material containing abrasive particles that are easily breakable less likely to break due to its buffering effect, and the breakage of the brush material caused by violent vibration generated during iron plate polishing. Is advantageously prevented.

[0007]

However, while the above-mentioned composite brush material has the above-mentioned features, it has a structure in which a filament containing abrasive particles is braided and covered with fine filaments.
It is a bottleneck that the roll price becomes extremely expensive due to the high cost of the material itself and the increase in the number of processes, and it is not possible to cope with the cost reduction of the product (rolled steel sheet).

The present invention is to provide a brush roll which has the effect of preventing breakage of the brush material in the above-mentioned brush roll while having a wiping effect and at the same time achieving a significant cost reduction.

[0009]

According to the present invention, as a means for solving the above-mentioned problems, a large number of disk brushes are inserted through a shaft through a shaft hole formed in the center of a disk, and the disk brushes are connected to each other. A non-woven fabric is annularly interposed between the disc brushes, and the diametrical width of the non-woven fabric is set between the brush bundle planting bases and beyond the outer peripheral edge of the disk. The width was set to span the bundle, and a non-woven fabric interposed between the disk brushes was compressed to form a brush roll by tightening the disk brush.

As the brush material for forming the brush bundle, monofilaments containing abrasive particles were used, and a large number of the filaments were assembled into a brush bundle.

The use of the braided composite brush material as the brush material provides a breakage preventing effect and a good wiping effect, but has the disadvantage of low productivity and high cost as described above. It is.

[0012] On the other hand, a brush roll using a monofilament containing abrasive particles as a brush material in a naked state is used for the above-mentioned reason. This roll has good productivity and is extremely inexpensive, but it is subject to high vibration during operation. Frequent breakage of the brush material is a drawback.

When the brush material is strongly compressed, the edge (outer periphery) of the disk of each disk brush strongly presses the entire brush bundle over the entire length of the roll brush when the disk brush is strongly compressed. This is because a repeated twisting force is applied.

The non-woven fabric is interposed between the disk brushes beyond the compression line by the edge, and the compression force by the outer peripheral edge of the disc is absorbed by the non-woven fabrics to exert a large cushioning effect as a whole roll. As a result, breakage of the brush material on the compression line due to the high vibration is favorably prevented.

Further, by interposing the nonwoven fabric so as to extend beyond the outer peripheral edge of the disk to the vicinity of the tip of the brush bundle, a good wiping effect is exhibited, and the polishing is performed in combination with the polishing effect of the brush material containing abrasive particles. An effect can also be provided. In addition, since a monofilament containing bare abrasive particles can be applied as a brush material, an advantage of low cost can be enjoyed.

The present invention also relates to a brush roll comprising a channel brush formed by sandwiching a base of a brush material with a U-shaped metal band and spirally intimately wound around a shaft. Spirally interposed, the intervening width of the nonwoven fabric in the diameter direction is set to a width extending between the U-shaped band brackets and beyond the brim edge portion and between the brush materials, and the nonwoven fabric is set between the windings of the channel brush. A brush roll interposed in a compressed state was constructed.

Similarly to the above, when the brush material is broken and the channel brushes are compressed and brought into close contact with each other, the edge (mouth) of the U-shaped band of each channel brush strongly presses the entire brush material over the entire length of the roll brush. This is because the high vibration repeatedly applies a torsional force to the pressing portion.

The non-woven fabric is interposed between the channel brushes beyond the compression line by the edge, and the pressing force by the edge of the U-shaped metal band is absorbed by each non-woven fabric and exerts a large buffer effect as a whole roll. As a result, breakage of the brush material on the compression line at the edge of the U-shaped metal band due to the high vibration can be prevented well.

Further, by interposing a non-woven fabric so as to extend beyond the edge of the U-shaped metal band and to reach near the tip of the brush material,
A good wiping effect can be exhibited, and a polishing effect can be added together with the polishing effect of the brush material containing abrasive particles. As a result, as described above, since a monofilament containing bare abrasive particles can be applied as a brush material, the advantage of low cost can be enjoyed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, the disk type brush roll shown in FIGS. 1 to 6 will be described.

As shown in FIGS. 1, 3 and the like, a metal disk 2 is provided as an implant of the brush bundle 1. The disk 2 has a large number of brush bundle planting holes 3 arranged at intervals on the outer peripheral plate portion.

The brush bundle 1 is inserted into each of the brush bundle placement holes 3, and is folded in two so as to straddle the hole wall of the placement hole 3 so that the hair tips protrude in the radial direction to form the disk brush 4. I do.

The planting base of the brush bundle 1 is bound by a binding wire 5 on the outer peripheral plate of the disk 2. Small holes are formed on both sides of the brush bundle planting hole 3 so as to allow the binding wire 5 to pass through.
Perform unity. As the brush material 6 forming the brush bundle 1, a monofilament containing abrasive particles is used in a bare state, and a large number of the monofilaments are aligned and assembled to form the brush bundle 1.

As shown in FIG. 1A, the disk brush 4
Are inserted through a shaft 8 through a shaft hole 7 provided at the center thereof, and the disk brushes 4 are compressed in the axial direction to form a brush roll. A key groove 9a is coupled to an appropriate position on the periphery of the shaft hole 7, and the key groove 9a is engaged with a key 9b provided on the generatrix of the shaft 8, thereby enabling the integrated rotation with the fastened disk brush. .

Thus, the nonwoven fabric 10 is annularly interposed between the disk brushes 4. The intervening width of the non-woven fabric 10 in the diameter direction is from the base of the brush bundle planting base to the outer peripheral edge 1 of the disc 2
The width is set to be greater than 1 and between the bundles of brushes, and the nonwoven fabric 4 is interposed between the disk brushes 4 in a compressed state by tightening the disk brushes 4.

As shown in FIG. 5A, the non-woven fabric 10 is punched in a belt shape, and is formed into a circular shape as shown in FIG. 5B. . The non-woven fabric 10 punched in a strip shape has a cut 1 at its inner edge over its entire length.
2 are formed at intervals so as to prevent wrinkles from occurring at the inner peripheral edge when the circle is formed as shown in FIG. 5B.

Alternatively, as shown in FIG. 5C, the nonwoven fabric is punched out in a circular shape, and at the same time, a shaft hole 13 is punched out in the center, and the shaft hole 13 is inserted through the shaft 8 alternately with the disk brush 4. Compress in the direction and fasten.

The non-woven fabric 10 is made of synthetic resin fibers to provide water resistance, and its thickness is set so as not to form a harmful space between the disk brushes, that is, to form a striped density on the peripheral surface of the roll brush. A non-woven fabric of 1 mm or less, preferably in the range of 0.5 mm to 1 mm, is selected so as not to be formed, and a material having high flexibility and compression elasticity as a whole is used.

When a nonwoven fabric having a compression elasticity having the above-mentioned thickness is used, the disk brush becomes extremely thin due to the compression accompanying the strong compression, and it is possible to prevent formation of a harmful space between the disk brushes.

FIG. 1A, FIG. 2A,
As shown in FIG. 3A, the shafts 8 are arranged such that the brush bundles 1 overlap each other between the adjacent disk brushes 4.
And tighten it. In this case, the nonwoven fabric 10 is interposed between the overlapping brush bundles and brought into a compressed state.

Alternatively, as shown in FIGS. 1B, 2B, and 3B, the disk brushes 4 are arranged such that one of the brush bundles is interposed between the adjacent disk brushes 4 with a circumferential pitch being shifted between the adjacent brushes. 8 and tightening is performed. At this time, the nonwoven fabric 10 is folded and interposed between the brush bundle 1 and the disk 2 and is in a strongly compressed state. Therefore, one side of the nonwoven fabric 10 is pressed against the outer peripheral edge 11 of the disk 2 and the other side is pressed against the brush bundle.

As described above, the nonwoven fabric 10 is interposed between the brush bundles 1 reaching the level of L2 or L1 shown in FIG. The pressing force of the outer peripheral edge 11 of the plate is applied to the brush bundle group along the entire length of the roll via the nonwoven fabric 10. L3 in FIG. 1A indicates a compression line of the outer peripheral edge portion 11 of the disk.

The pressing force of the outer peripheral edge 11 of the disk is absorbed by the nonwoven fabrics 10, and the roll as a whole exerts a large buffering effect. As a result, breakage of the brush material 6 on the compression line L3 due to the high vibration is favorably improved.

When the brush bundles 1 between the adjacent disk brushes 4 are overlapped in the axial direction as shown in FIGS. 1A and 2A, or between the adjacent disk brushes 4 as shown in FIGS. 1B and 2B, In either case where one brush bundle is interposed between the other brush bundles and the semi-bundles are overlapped by half in the circumferential direction, the nonwoven fabric 10 is placed between the brush materials 6 of each overlapping bundle as shown in FIG. Intervene.

That is, due to the compression, the brush material 6 of one brush bundle diffuses and enters between the brush materials 6 of the other brush bundle, and accordingly, the nonwoven fabric 10 enters between the brush materials 6 of the other brush bundle. The structure is to enter. This means a configuration in which the compressive force and the flexibility of the nonwoven fabric 10 with respect to the compressive force are set to be in the above-described state.

As an example, the non-woven fabric 10 is interposed so as to reach the vicinity of the bristle tip of the brush bundle 1 beyond the outer peripheral edge portion 11 of the disk. In FIG. 1A, L1 indicates the intervening level of the nonwoven fabric 10 according to this embodiment. With this configuration, the brush material 6 exhibits a polishing effect, and the nonwoven fabric exhibits a wiping effect as the wear of the brush material 6 progresses. That is, it has an abrasive effect of wiping the abrasive powder polished by the brush material 6 with the nonwoven fabric 10.

Further, as an example, when the nonwoven fabric 10 is interposed between the disk brushes 4 beyond the outer peripheral edge portion 11 of the disc, in other words, when the nonwoven fabric 10 is interposed beyond the compression line L3 by the outer peripheral edge portion 11 of the disc, The intervening width in the diameter direction of the nonwoven fabric 10 is set to a level L2 which exceeds the compression line L3 but does not reach the level L1 near the tip of the hair. That is, the intermediate width is set between L1 and L3.

6A and 6B, the diameter R1 of the nonwoven fabric 10 is made larger than the diameter R2 of the disk 2, and the shaft of the disk 2 is set. The diameter R3 of the hole 6 is substantially the same as the diameter of the shaft 8, and the diameter R4 of the shaft hole 13 of the nonwoven fabric 10 is larger than the diameter R3 of the shaft hole 7 of the disc 2.

FIG. 7 shows an embodiment in which the present invention is applied to a channel type brush roll. Channel brush 14
Folds the brush material 6 containing abrasive particles naked and folds it over the core wire 15, and attaches the base to the U-shaped band 16
This long brush is attached to the shaft 8
And wound closely together while being spirally compressed to form a roll brush.

The nonwoven fabric 10 is spirally interposed between the windings of the channel brush 14.

The width of the non-woven fabric in the diametric direction is set so as to extend from between the U-shaped band metal fittings 16 and beyond the brim opening 17 to the space between the brush materials 6. Insert in a compressed state between the turns.

The nonwoven fabric 10 is set to have an intervening width reaching the level L2 or L1 shown in FIG. 1A, similarly to the disk-shaped brush roll. In any case, the nonwoven fabric 10 is made of U
The width of the band member 16 is set to be greater than the lip 17, in other words, the pressing line L of the lip 17 against the brush material 6.
The width is set to an interposition width exceeding 3 so as to absorb and cushion the pressing force of the lip 17 on the compression line.

Therefore, like the disk type brush roll,
The torsional force due to the high vibration of the brush material 6 at the compression line L3 is reduced, and breakage of the brush material 6 from the same line is effectively prevented.

In the channel type brush roll, the non-woven fabric 10 interposed between the windings is interposed between the rim portions 17 of the U-shaped metal band 16 and is brought into direct contact therewith and compressed.
Achieve good breakage prevention effect.

The non-woven fabric 10 was placed at the level L2 shown in FIG.
Alternatively, when the width is set to the intervening width reaching L1, the structure has the same function as that described above. The material and thickness of the nonwoven fabric 10 are the same as those described above, and the remaining configuration can be applied to the channel type brush roll.

[0046]

According to the present invention, the nonwoven fabric interposed between the disc brushes or between the windings of the channel brush is compressed together with the brush material on the compression line formed by the outer peripheral edge portion of the disk or the edge portion of the U-shaped metal band. It exhibits an excellent buffering effect and satisfactorily prevents breakage of the brush material from above the compression line due to high vibration during brush roll operation.

Also, by setting the nonwoven fabric interposed beyond the edge of the U-shaped metal band or the outer peripheral edge of the disk to have an interposed width reaching the vicinity of the tip of the brush material, a wiping effect is also provided,
A brush roll using a brush material containing abrasive particles naked also has an abrasive effect.

[0048] Thus, while enjoying the inexpensive advantage of the brush roll using the brush material containing abrasive particles naked, the disadvantage can be eliminated and the demands of the site can be met.
