  The roll brush of Patent Document 1 is manufactured by forming a channel brush into a coil brush, the coil brush being formed by one channel brush, and the coil brush being extrapolated to a roll. For this reason, the coil brush is arranged at a substantially right angle with respect to the longitudinal direction of the roll. Therefore, the inclination angle of the coil brush with respect to the direction orthogonal to the longitudinal direction of the roll is small, and the brush material is applied to the surface to be cleaned as the roll brush rotates. A gap portion that does not contact, that is, a brush mark is generated. Since the brush mark as described above becomes a cleaning residue on the surface to be cleaned, the roll brush has a problem that the surface to be cleaned cannot be cleaned uniformly and the cleaning performance is poor.

In the channel brush type brush roll of Patent Document 2, the density of the hair material tip is set to 25 / cm ² or more and 250 / cm ² or less in order to prevent the cleaning performance from being deteriorated due to cleaning residue (brush mark or the like). However, when the density at the tip of the bristle material is small, gaps are generated between the bristle materials, so the bristle material does not contact the surface to be cleaned in the gaps as described above. The object cannot be completely removed. In addition, when the density of the tip of the bristle material is large, the object removed from the surface to be cleaned is captured between the bristle material and difficult to be removed outside the channel brush type brush roll. Along with this, the object captured between the hair materials falls on the surface of the surface to be cleaned and reattaches to the surface to be cleaned. Therefore, there has been a problem that it is difficult to efficiently and reliably remove the object from the surface to be cleaned.

  When the brush roll of Patent Document 3 rotates in the direction opposite to the direction in which the object such as a foreign object is fed from the symmetry axis toward the end of the roll body, the object is symmetrically set at the center of the roll body. Since it accumulates toward the shaft, the object cannot be excluded outside the brush roll. Therefore, in order to efficiently and reliably remove the object from the surface to be cleaned, there is a problem that the rotation direction of the brush roll is limited.

  The present invention solves the above-described conventional problems, and does not generate cleaning residue on the surface to be cleaned, and is not limited to the rotation direction of the brush roll, and efficiently removes objects such as foreign matters. It is an object of the present invention to provide a brush roll having high cleaning performance and a cleaning device equipped with the brush roll.

In order to solve the above-described conventional problems, the brush roll of claim 1 is a cleaning, cleaning, polishing, and surface of a surface to be cleaned made of a steel plate, a non-ferrous metal plate, a resin plate, a glass plate, or a film-like resin composition. In the brush roll that performs processing or the like, the brush roll has a substantially rod-shaped or cylindrical shaft, and a brush portion that is spirally wound around the outer periphery of the shaft, and the brush portion has a substantially U-shaped strip shape. 3 or more brush bodies made of a channel brush composed of a body and a bristle material made of multifilament sandwiched between the belt and the core wire are provided in parallel, and at least one brush body is another together with are configured in the brush body and the different line diameters or different bristle length of the brush bristle materials, Yes is formed by winding in a spiral manner around the circumference of the shaft, before the adjacent The gap between the belt-like bodies of the brush body is set to be equal to or less than the width of the belt-like body, and both end portions of the three or more brush bodies are fixed to the outer circumference equally divided portions near the both end portions of the shaft. In the brush roll, two or more other brush bodies are arranged in a pitch where one brush body is spirally wound around the outer periphery of the shaft. Therefore, the brush roll has a larger inclination angle with respect to the direction perpendicular to the longitudinal direction of the shaft of each brush body compared to the case where the brush roll is spirally wound around the outer periphery of the shaft by only one brush body. Can be set. For this reason, as the brush roll rotates, the brush bristle material makes contact with the surface to be cleaned with a large contact area. Thus, no cleaning residue is generated on the surface to be cleaned, and the brush roll uniformly cleans the surface to be cleaned.

  Further, since the brush roll is formed with a large inclination angle with respect to the direction orthogonal to the longitudinal direction of the shaft, objects such as foreign matters removed from the surface to be cleaned by the brush bristle are brushed. Even if it is captured between the hair materials, it is difficult to fall on the surface of the surface to be cleaned as the brush roll rotates. Therefore, reattachment of the object to the surface to be cleaned is prevented.

  Further, since the gap between the brush bodies of the brush roll is set to a dimension equal to or less than the width of the belt-like body, the occurrence of the brush mark, that is, the gap where the brush bristle material does not contact the surface to be cleaned is suppressed. .

  Furthermore, the brush roll rotates to move objects such as foreign objects along the inclination angle of the brush body and remove it outside the brush roll. However, the brush body spirals in the same direction around the outer periphery of the shaft. Since it is formed by being wound into a shape, the object is excluded to the outside from either one end of the brush roll without being limited to the rotation direction of the brush roll.

  The brush roll according to claim 2 is the brush roll according to claim 1, in which the gaps between the strips of adjacent brush bodies are formed with substantially the same width, and the brush body made up of channel brushes is fixed. Since it suffices to wrap around the outer periphery of the shaft with a gap, it is easy to form the brush portion, that is, to attach the brush body to the shaft. Therefore, since the productivity of the brush roll is improved, the brush roll can be provided at a low cost. Moreover, since the clearance gap between the strips of a brush body is constant, the rotational balance of a brush roll improves and the core blur accompanying rotation is suppressed.

  The different brush bristle materials are, for example, hardness, rigidity due to the material, the wire diameter of the brush bristle material, the bristle length of the brush bristle material, the cross-sectional shape of the brush bristle material, and the like.

A cleaning device according to a third aspect of the present invention includes a brush roll according to the first or second aspect , a driving unit that rotationally drives the brush roll, and a plurality of spraying liquids such as cleaning liquid on the brush roll and / or a surface to be cleaned. It has a nozzle, and does not generate a brush mark, that is, a cleaning residue on the surface to be cleaned, and has excellent cleaning performance.

  Since the brush roll of claim 1 can set a large inclination angle in the direction orthogonal to the longitudinal direction of the shaft of the brush body, it does not leave a brush mark on the surface of the surface to be cleaned, and has excellent cleaning performance. In addition, it is possible to efficiently and reliably remove objects such as foreign matters.

  Since the brush roll of Claim 2 can be easily attached to the shaft of the brush body and the productivity is improved, the brush roll can be provided at a low cost. Moreover, since the rotation balance of a brush roll improves, the core blur accompanying rotation can be suppressed.

Since the cleaning apparatus of claim 3 is equipped with a brush roll having excellent cleaning performance, no brush mark, that is, cleaning residue is generated on the surface to be cleaned, and excellent cleaning performance can be exhibited. .

  Embodiments of the present invention will be described below with reference to the drawings. In addition, this invention is not limited by this Example.

Example 1
1A is a partial front view of a brush roll according to the first embodiment of the present invention, FIG. 1B is a side view of the brush roll, and FIG. 1C is a view of the brush body from the front side. FIG. 2 is a partial cross-sectional view of the brush roll in the first embodiment of the present invention, and FIG. 3 is a perspective view of the manufacturing state of the channel brush as viewed from the front side.

1A and 1B, the brush roll 1 is made of a metal material such as iron or aluminum, or a synthetic resin material such as polyvinyl chloride or polyacetal, and has a substantially cylindrical shape having a hollow portion 9. The brush part 2 which consists of three brush bodies 4a, 4b, 4c is attached and formed on the outer periphery of the shaft 3. Three brush body 4a, 4b, 4c, along with being wound spirally on the outer periphery of the shaft 3 at a pitch P _1, respectively, an inclined angle theta ₁ in the direction orthogonal to the longitudinal direction of the shaft 3 Are installed in parallel. The shaft 3 may be a solid substantially rod shape.

In FIG. 1C, brush bodies 4a, 4b and 4c are a strip-like body 6 having a long U-shaped cross section made of a metal material such as iron, aluminum and stainless steel, and a metal such as iron, aluminum and stainless steel. It is formed by a long channel brush 5 in which a brush bristle material 8 is sandwiched between a long core wire 7 having a substantially round cross section made of a material. When the brush bodies 4a, 4b, and 4c are mounted on the outer periphery of the shaft 3, as shown in FIG. 1B, the three brush bodies 4a, The starting points S ₁ , S ₂ , S _{3 of} 4b, 4c are fixed via the fixing part 10 by welding and spirally wound, and at the three outer peripheral equal parts near the other end of the shaft 3, The end points (not shown) of the three brush bodies 4a, 4b, 4c are fixed and formed through fixing parts (not shown) by welding.

The inclination angle θ ₁ of the three brush bodies 4a, 4b, 4c with respect to the longitudinal direction of the shaft 3 is preferably set to 4 ° or more and 12 ° or less. When the inclination angle θ ₁ is less than 4 °, the object such as the foreign matter removed from the surface to be cleaned is difficult to move in the longitudinal direction of the shaft 3 because the angle is too small, and the object is efficiently and reliably removed from the brush roll 1. Difficult to exclude outside. On the other hand, when the inclination angle θ ₁ exceeds 12 °, the angle is too large, and the brush bristle material 8 easily comes into contact with the surface to be cleaned up to the vicinity of the shaft 3, that is, the neighborhood of the belt-like body 6. , Cutting is likely to occur, leading to a reduction in durability of the brush roll 1.

Further, each of the brush bodies 4a, 4b, the pitch _{P 1} when 4c is mounted wound around the outer periphery of the shaft 3, is preferably set at 20mm or 50mm or less. If the pitch P ₁ is less than 20 mm, since the bristles of brush 8 intervals too small are concentrated, the object of such foreign matter removed from the cleaned surface is captured between the brush hairs 8, the longitudinal shaft 3 It is difficult to move the object in the direction, and it is difficult to efficiently and reliably exclude the object outside the brush roll 1. On the other hand, if the pitch P ₁ is more than 50 mm, less planting amount of the brush hairs 8 intervals are too wide, it is difficult to remove quickly and reliably object from the cleaning surface.

  In the present embodiment, the three brush bodies 4a, 4b, 4c are provided on the outer periphery of the shaft 3, but of course, four or more may be used.

  Next, the configuration of the brush roll 1 will be described in detail with reference to FIG.

In FIG. 2, the brush roll 1 is composed of three brush bodies 4 a, 4 b, and 4 c, each of which comprises a band-like body 6 and a channel brush 5 in which a brush bristle material 8 is sandwiched between core wires 7. It is formed as the brush part 2 wound and mounted in parallel. One brush body 4a is mounted in a spiral manner around the circumference of the shaft 3 with a pitch P _1. Between the pitch P ₁ of as above, the other two brushes member 4b, with 4c are parallel, the other two brushes member 4b, 4c to the outer periphery of the shaft 3 with a pitch P ₁ helix It is wound in a shape and attached.

Further, the brush member 4a and the brush body 4b adjacent the brush body 4b and the brush body 4c, the gap G ₁ of the brush body 4c and the brush body 4a is formed at substantially the same dimensions. The dimensions of the gap _{G 1} is a brush body 4a, 4b, is set at less than or equal to the width _{W 1} of the strip 6 that constitutes the 4c. If the size of the gap G ₁ is, more than the width W ₁ of the strip 6, is too wide a gap G _1, with the rotation of the brush roll 1, when the brush bristle material 8 comes into contact with the cleaned surface, cleaned surface A gap portion where the brush bristle material 8 does not come into contact, that is, a brush mark is likely to be generated, and a cleaning residue is generated on the surface to be cleaned. The width _{W 1} of the strip 6 is suitably 5mm or 10mm or less. When the width W ₁ is less than 5 mm, planting設量less brush bristles 8, it is difficult to remove quickly and reliably object from the cleaning surface. On the other hand, when the width W ₁ exceeds 10 mm, the strength of the strip 6 made of a metal material is too strong, it is difficult to form by winding in a spiral manner around the circumference of the shaft 3, in fabricating the brush roll 1 Workability is inferior. Incidentally, the brush body 4a adjacent, 4b, the gap G ₁ of 4c, at partially variation, although sometimes spread, not lead to performance degradation of the brush roll 1, is within the scope of the present invention .

In the present embodiment, the width W ₁ of the belt-like body 6 and the gap G ₁ between the adjacent brush bodies 4a, 4b, 4c are formed with substantially the same dimensions, but the width W ₁ and / or the gap G ₁ is may be each other are formed by different dimensions.

  Next, the manufacturing method of the brush roll 1 is demonstrated using FIG.

  First, as shown in FIG. 3, a long brush bristle material 8 having a substantially round cross section is prepared. The brush bristle material 8 is made of synthetic fibers such as nylon, polyester, acrylic, vinylon, polypropylene, polyvinyl chloride, polyethylene, vinylidene and polyurethane, semi-synthetic fibers such as acetate and promix, regenerated fibers such as rayon, cupra and lyocell, It consists of natural fibers such as cotton, wool, and silk, and metal fibers such as piano wire, hard steel wire, stainless steel wire, oil temper wire, brass wire, and phosphor bronze wire. The cross-sectional shape of the brush bristle material 8 is not particularly limited, and other than the generally round shape, for example, a polygon such as a triangle or a quadrangle, a star shape, a saddle shape, a cross shape, an M shape, an N shape, or the like. It may have a cross-sectional shape. Further, it may be solid or hollow. Furthermore, there is no problem with either monofilament or multifilament. The material, shape, and the like of the brush bristle material 8 are appropriately determined in consideration of the environment in which the brush roll 1 is used, the cost, and the like.

  When a plurality of brush bristle materials 8 as described above are prepared, the brush bristle material 8 is installed on the base 35 so that the substantially central portion of the brush bristle material 8 overlaps the upper part of the belt-like body 6. Next, using the vertical roll 36, the brush bristle material 8 is sandwiched by the core wire 7, and the core wire 7 is pushed into the band-shaped body 6 having a substantially U-shaped cross section. Next, the belt-like body 6 is caulked from both sides using the lateral rolls 37 installed on both sides of the belt-like body 6. As a result, as shown in FIG. 1C, a long channel brush 5 is formed in which the substantially central portion of the long brush bristle material 8 is sandwiched and folded between the core wire 7 and the belt-like body 6. .

Next, as shown in FIG. 1 (b), one end of one of the brush body 4a, i.e. the start point S ₁ is near one end of the shaft 3 is fixed through the fixing portion 10 by welding, as FIG. 1 (a), it is mounted wound helically with a pitch P ₁ to the outer periphery of the shaft 3. The other end of the brush body 4a, that is, the end point (not shown) is fixed to the vicinity of the other end of the shaft 3 via a fixing part (not shown) by welding. Similarly, the other two brushes member 4b, the outer periphery of the 4c is a shaft 3, while being mounted between the pitch P ₁ of the brush body 4a, the other two brushes member 4b, 4c even have a pitch P ₁ The brush part 2 is formed on the outer periphery of the shaft 3 by being wound around the outer periphery of the shaft 3 and fixing the start points S ₂ and S ₃ and the end point in the vicinity of both ends of the shaft 3 via the fixing part 10 by welding. The brush roll 1 thus manufactured is manufactured as shown in FIG.

  The operation and action of the brush roll 1 configured as described above are as follows.

In the brush roll 1, the other two brush bodies 4 b and 4 c are arranged between the pitches P ₁ in which one brush body 4 a is spirally wound around the outer periphery of the shaft 3. Accordingly, the brush roll 1 has a longitudinal direction of the shaft 3 of each of the brush bodies 4a, 4b, and 4c as compared with the case where the brush roll 1 is spirally wound around the outer periphery of the shaft 3 by only one brush body 4a. the inclination angle theta ₁ towards the direction perpendicular can be set large. For this reason, as the brush roll 1 rotates, the brush bristle material 8 comes into contact with the surface to be cleaned while ensuring a large contact area. Generation | occurrence | production is suppressed and a cleaning residue does not arise in a to-be-cleaned surface, but the brush roll 1 wash | cleans a to-be-cleaned surface uniformly.

Further, the brush roll 1 is formed by spirally wound around the outer periphery of the shaft 3 by only one brush body 4a, and the brush bodies 4a, 4b, 4c are orthogonal to the longitudinal direction of the shaft 3. because it is formed by setting a large angle of inclination theta ₁ to the direction of, even if the object of the foreign matter removed by the brush hairs 8 from the cleaning surface is captured between the brush hairs 8, the brush It is difficult to fall on the surface of the surface to be cleaned as the roll 1 rotates. Therefore, reattachment of the object to the surface to be cleaned is prevented.

In addition, the brush roll 1 rotates to move the object along the inclination angle θ ₁ of the brush bodies 4a, 4b, and 4c and excludes the object outside the brush roll 1, but the brush bodies 4a, 4b, and 4c. Is formed by being spirally wound around the outer periphery of the shaft 3 in the same direction, and thus is not limited to the rotation direction of the brush roll 1, and the object from either one end of the brush roll 1. To the outside.

Additionally, the brush roll 1, the brush body 4a adjacent, 4b, since the gap _{G 1} of 4c is are formed in substantially the same dimensions, the brush body 4a made of channel brush 5, 4b, 4c a fixed gap G ₁ is wound around the outer periphery of the shaft 3, so that the brush portion 2 can be formed, that is, the brush bodies 4a, 4b, and 4c can be easily attached to the shaft 3. Therefore, since the productivity of the brush roll 1 is improved, the brush roll 1 can be provided at a low cost. Further, the brush member 4a, 4b, 4c gap G ₁ is for a fixed, improved rotational balance of the brush roll 1, runout due to the rotation is restrained.

  Next, the cleaning performance of the brush roll 1 of the present invention was tested. The measurement was performed as shown below, and the results are shown in Table 1.

As Example 1, a substantially central portion in the longitudinal direction of a long brush bristle material 8 made of nylon having a wire diameter of 0.2 mm is sandwiched between a long belt-like body 6 made of iron and a core wire 7. At the same time, the three brush bodies 4 a, 4 b, 4 c composed of the long channel brush 5 were formed. The hair length of the folded brush bristle material 8 was set to 60 mm. Then, substantially the outer circumference of the cylindrical shaft 3 of the iron 360mm is and length with 90mm in diameter, three brush body 4a, 4b, 2 mm width of the gap _{G 1} of the 4c, adjacent the brushes bodies 4a, 4b, the pitch _{P 1} of 4c is set to 30mm winding spirally to form a brush portion 2. The width W ₁ of the belt-like body 6 was 8 mm, and the inclination angle θ _{1 with} respect to the direction perpendicular to the longitudinal direction of the shaft 3 of the three brush bodies 4a, 4b, 4c was formed to be about 5.5 °. In addition, the start points S ₁ , S ₂ , S ₃ and the end point of the channel brush 5 were fixed to the outer periphery of the shaft 3 at three equally-divided positions in the vicinity of both ends via fixing portions 10 by welding. Then, two brush rolls of Example 1 were manufactured according to the above procedure.

As Comparative Example 1, two brush rolls 1 in which the brush portion 2 was formed with one brush body 4a were produced. Brush roll 1 of Comparative Example 1, the outer periphery of the shaft 3, the brush body 4a, the width of the gap _{G 1} adjacent 2 mm, the width _{W 1} of the strip 6 8 mm, the pitch _{P 1} of the brush body 4a to 10mm It was set and wound into a spiral. Other conditions such as the dimensions of the shaft 3 are the same as those of the brush roll 1 of the first embodiment. The inclination angle theta ₁ towards the direction perpendicular to the longitudinal direction of the shaft 3 of the brush body 4a is formed on the approximately 1.8 °.

As Comparative Example 2, two brush rolls 1 having the brush part 2 formed by two brush bodies 4a and 4b were produced. Brush roll 1 of Comparative Example 2, the outer periphery of the shaft 3, the brush body 4a, the 4b, 2 mm width of the gap _{G 1} adjacent the width _{W 1} of the strip 6 8 mm, the brushes bodies 4a, 4b pitch It was formed by winding spirally by setting P ₁ to 20 mm. Other conditions such as the dimensions of the shaft 3 are the same as those of the brush roll 1 of the first embodiment. Incidentally, the two brush bodies 4a, the inclination angle theta ₁ towards the direction perpendicular to the longitudinal direction of the shaft 3 of 4b was formed to approximately 3.5 °.

  Next, two brush rolls 1 of Example 1, Comparative Example 1 and Comparative Example 2 each configured as described above were attached to the plate tester in a pair of upper and lower, respectively, and a constant rotational speed of 150 rpm. A hot dip galvanized steel sheet coated with artificial dirt on one side is prepared, and the shaft is 3 mm from the virtual circle drawn by the tip of the brush part 2 attached to the outer periphery of the shaft 3 rotating at the rotational speed. The hot dip galvanized steel sheet is set at a position close to the direction of 3 so that its dirty surface faces the shaft 3, and the galvanized steel sheet is 100 mpm while spraying cleaning water at a spraying amount of 7 L per minute. At a peripheral speed, the brush roll 1 attached in a pair of upper and lower sides was passed through, and the brush portion 2 was brought into contact with the dirty surface of the steel plate to remove the stain on the steel plate.

And the brightness of the part which removed the stain | pollution | contamination by the brush part 2 in the stain | pollution | contamination surface of a steel plate was measured with the color difference meter NR-1 by Nippon Denshoku Industries Co., Ltd., and the washing | cleaning performance was judged by the following reference | standard.
○ ・ ・ ・ Brightness improvement is +5 or more △ ・ ・ ・ Brightness improvement is +3 or more and less than +5 × ・ ・ ・ Brightness improvement is less than +3

Moreover, the brush mark of the steel plate after the test, that is, the presence or absence of cleaning residue was visually observed and judged according to the following criteria.
○ ・ ・ ・ No brush mark × ・ ・ ・ There is a brush mark

From the above test results, the brush roll 1 of the first embodiment, the brushes bodies 4a, 4b, since the inclination angle theta ₁ towards the longitudinal direction of the shaft 3 of the 4c is large, with the rotation of the brush roll 1, the brush bristles 8 Since the contact area with the steel sheet is secured with a large contact area, the gap where the brush bristle material 8 does not contact the steel sheet, that is, the generation of brush marks is suppressed, and no cleaning residue is generated on the steel sheet, resulting in excellent cleaning performance. I had it.

Brush roll 1 of Comparative Example 1, since the inclination angle theta ₁ towards the longitudinal direction of the shaft 3 of the brush body 4a is extremely small contact area against the steel plate of the brush bristles 8 due to the rotation of the brush roll 1 is extremely narrow, the steel plate Since a gap portion where the brush bristle material 8 does not contact, that is, a brush mark is generated and a cleaning residue is generated on the steel plate, the cleaning performance is very poor.

Brush roll 1 of Comparative Example 2, since the brushes bodies 4a, the inclination angle theta ₁ against longitudinal 4b of the shaft 3 is small, with the rotation of the brush roll 1, the brush bristles 8 broadly secure a contact area against steel The cleaning performance is inferior because the gap portion where the brush bristle material 8 does not come into contact with the steel plate, that is, the brush mark is generated and the cleaning residue is generated on the steel plate.

(Example 2)
FIG. 4 (a) is a perspective view of a brush bristle material used for the first brush body constituting the brush roll in the second embodiment of the present invention, and FIG. 4 (b) is a second embodiment of the present invention. FIG. 4C is a perspective view of the brush bristle material used for the second brush body constituting the brush roll in the example, and FIG. 4C is used for the third brush body constituting the brush roll in the second embodiment of the present invention. It is a perspective view of the brush bristle material. Example 2 is a form in which the material of the brush bristle material constituting each of the three brush bodies of Example 1 is different. In addition, about the same member as the brush roll in the said 1st Example, the same code | symbol is attached | subjected and the detailed description is abbreviate | omitted.

  In FIG. 4A, the brush bristle material 28a is formed by adhering a plurality of granular abrasive grains 25 to the outer periphery of a long synthetic fiber 29 having a substantially round cross section. The abrasive grain 25 is blended by about 20 to 30% in a weight ratio with the synthetic fiber 29. Since the brush bristle material 28a contains the abrasive grains 25 as described above, the brush bristle material 28a is configured as the first brush body 4a, and when formed on the brush roll 1, the bristle is extremely strong and the surface to be cleaned is Objects that are firmly attached, for example, synthetic resins such as paint mist and paint can be scraped off.

  The synthetic fiber 29 constituting the brush bristle material 28a is made of nylon, polyester or the like, and has a wire diameter of about 0.1 to 0.8 mm. The abrasive grains 25 are inorganic substances such as aluminum oxide, silicon carbide, diamond, etc., and the particle diameter is about 0.1 to 10 μm. When the abrasive grains 25 are fixed to the synthetic fibers 29, if a silane coupling agent is used, the abrasive grains 25 can be firmly adhered to the synthetic fibers 29, and the abrasive grains 25 fall off from the brush roll 1 during cleaning. This can be prevented. A silane coupling agent is an organosilicon monomer having two different reactive groups in the molecule, one reactive group is a reactive group that chemically bonds to an inorganic substance, and the other reactive group is chemically bonded to an organic substance. It is a reactive group. Therefore, since the silane coupling agent chemically bonds the inorganic abrasive grains 25 and the organic synthetic fibers 29, the abrasive grains 25 can be firmly bonded to the synthetic fibers 29.

  In FIG.4 (b), the brush bristle material 28b is a long synthetic fiber which has a substantially round cross section, and consists of nylon, polyester, etc. The wire diameter of the brush bristle material 28b is about 0.1 to 0.8 mm. When the brush bristle material 28b is configured as the second brush body 4b and is formed on the brush roll 1, it is made of synthetic fibers having excellent wear resistance, so among the objects attached to the surface to be cleaned, Even when it comes into contact with a hard inorganic substance such as iron powder or stone, iron powder, stone or the like can be removed without causing breakage, hair breakage or the like.

  In FIG.4 (c), the brush bristle material 28c is the twisted yarn 26 formed by twisting together the several single yarn 27 which consists of elongate synthetic fiber which has a substantially round cross section. The single yarn 27 is made of nylon, polyester or the like, and has a wire diameter of about 10 to 100 μm. The number of twists of the single yarn 27 is not particularly limited. Since the brush bristle material 28c is configured as the third brush body 4c and formed on the brush roll 1, the brush bristle material 28c is formed by the twisted yarn 26. Therefore, the brush bristle material 28c is repeatedly brought into contact with the surface to be cleaned. The tip of 28c is loosened, and dust such as fiber debris adhering to fine uneven portions of the surface to be cleaned can be scraped off.
