  As a conventional brush roll of this type and a cleaning apparatus equipped with the brush roll, a coil brush is formed by closely spirally winding a channel brush formed by holding the base of a brush material in a channel, and the coil brush is used as a roll. The roll brush formed by extrapolation includes a braking flange facing the outer surface of the coil brush, and the braking brush engages with the channel end surface of the winding end of the channel brush forming the coil brush on the braking flange.

  The roll brush of Patent Document 1 is manufactured by forming a channel brush into a coil brush by forming a coil brush with a single channel brush and extrapolating the coil brush to the roll by tight spiral winding. For this reason, since the coil brush is disposed at a substantially right angle to the longitudinal direction of the roll, the inclination angle of the coil brush with respect to the perpendicular to the roll axis is extremely 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. If the inclination angle is set to be large with one channel brush, the pitch of the channel brush is widened, and the gap portion where the brush material does not come into contact with the surface to be cleaned becomes large.

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 close to 25 / cm ² , 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. Therefore, it is impossible to completely remove a foreign object from the surface to be cleaned. In addition, when the density of the tip of the bristle material is close to 250 / cm ² , the object removed from the surface to be cleaned is captured between the bristle materials and is difficult to be excluded outside the channel brush type brush roll. Along with the rotation of the channel brush type brush roll, the object captured between the bristle materials falls on 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 there is no occurrence of cleaning residue on the surface to be cleaned, and it is not limited to the rotation direction of the brush roll. It aims at providing the brush roll which has the high washing | cleaning performance which removes the target object, and the washing | cleaning apparatus carrying 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 rotating shaft and a brush portion that is spirally wound around the outer periphery of the rotating shaft, and the brush portion has a substantially U-shaped cross section. And three or more brush bodies made of a channel brush composed of the band-shaped body and a brush bristle material held together with the core wire by the band-shaped body are provided in parallel, and spirally wound around the outer periphery of the rotating shaft. The width of the gap between at least one adjacent brush body is different from the width of the gap between other adjacent brush bodies, and the brush body is an axis of the rotating shaft. Drooping heart Against which has an inclination angle of 45 ° or less, the start and end points of each of the brush body, in which equally portion of the outer periphery of the rotating shaft are formed by fixing at fixing means, the brush roll one Two or more other brush bodies are arranged between the pitches in which the brush bodies are spirally wound around the outer periphery of the rotating shaft. Therefore, the brush roll has an inclination angle with respect to the perpendicular to the axis of the rotation axis of each brush body, as compared with the case where one or two brush bodies are spirally wound around the outer periphery of the rotation shaft. Can be set large. 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.

  In addition, as described above, the brush roll is formed so that one or two brush bodies are spirally wound around the outer periphery of the rotation shaft, and each brush body has an axis center of the rotation shaft. Since it is formed with a large inclination angle with respect to the vertical line, even if objects such as foreign matter removed from the surface to be cleaned by the brush bristle material are caught between the brush bristle material, the rotation of the brush roll Difficult to fall on the surface to be cleaned. For this reason, reattachment of an object such as a foreign object to the surface to be cleaned is prevented.

  The inclination angle with respect to the perpendicular to the axis of the rotation axis of the brush body is set to 45 ° or less. When the angle of inclination with respect to the perpendicular to the axis of the rotation axis of the brush body exceeds 45 °, the stress at the time when the brush bristle material comes into contact with the surface to be cleaned tends to concentrate on the side edge of the belt. At the side edge of the brush, the brush bristle is fuzzed, and fatigue refraction occurs from the portion with the fur, and the brush bristle breaks. Therefore, the cleaning performance of the brush roll deteriorates and the durability decreases. In the brush roll of the present invention, since the inclination angle with respect to the perpendicular to the axis of the rotation axis of the brush body is set to 45 ° or less, the brush bristle material abuts the surface to be cleaned on the side edge of the belt-like body. Since the stress at the time is difficult to concentrate and the bristle of the brush bristle material is not likely to be broken, excellent cleaning performance is exhibited over a long period of time.

Furthermore, the brush roll moves by rotating the object such as a foreign object along the inclination angle of the brush body and removes it outside the brush roll. However, the brush body is in the same direction on the outer periphery of the rotation shaft. Since it is formed by being spirally wound, it is not limited to the rotation direction of the brush roll, and an object such as a foreign object is excluded from one end of the brush roll. In addition, since the starting point and end point of each brush body are formed by fixing means at equal locations on the outer periphery of the rotating shaft, the brush roll suppresses the occurrence of core blurring of the rotating shaft accompanying rotation. In addition, since stable rotation is maintained, excellent cleaning performance is exhibited over a long period of time.

  The brush roll according to claim 2 is the brush roll according to claim 1, in particular, the brush portion is formed with a band-shaped body constituting at least one brush body having a width different from that of the belt-shaped body constituting the other brush body. If a brush bristle material having the same material, wire diameter, shape, and bristle length is used, a brush body composed of a strip-shaped body having a small width is a brush composed of a strip-shaped body having a large width. Compared to the body, the amount of flocking of the brush bristle material is reduced. By changing the amount of brush bristle material depending on the brush body, it is possible to change the strength of the bristle of the bristle material, and bring the bristle material into contact with the surface to be cleaned with different contact force and pressing force. be able to. In other words, the brush bristle material of the brush body composed of the strip-shaped body having a small width has a smaller amount of flocking than the brush bristle material of the brush body composed of the strip-shaped body having a large width, so that the hair waist is flexible. When the brush bristle material comes into contact with the surface to be cleaned, the followability to the surface to be cleaned is improved. On the other hand, the brush bristle material of a brush body composed of a strip having a large width has a larger amount of flocking than the brush bristle material of a brush body composed of a strip having a small width, so that the hair waist is rigid. When the brush bristle material comes into contact with the surface to be cleaned, the pressing force against the surface to be cleaned is improved.

  By the way, on the surface to be cleaned, there are various objects such as paint mist, paint, organic matter made of synthetic resin such as urethane peeled from the conveyor belt, inorganic matter such as iron powder and stone, dust made of fiber debris, etc. Adhering and depositing. Also, the state of adhesion to the surface to be cleaned varies from an object that is firmly pressure-bonded, such as an organic substance made of synthetic resin, to an object that is simply attached to the surface, such as an inorganic substance or dust. Also, the hardness varies from a hard object such as an inorganic substance such as iron powder or stone to a soft object such as dust. Therefore, the brush bristle material of the brush body made of a band-shaped body having a small width configured so that the hair and hips are flexible is configured to reliably remove objects such as inorganic substances and dust and to make the hair and hips rigid. Objects such as organic substances made of synthetic resin are efficiently removed by the brush bristle material of the brush body made of a strip having a large width. As described above, by changing the width of the band-shaped body constituting the brush body, a change in strength is imparted to the bristle and waist of the brush bristle material, such as foreign substances having various properties attached and deposited on the surface to be cleaned. The object is removed efficiently and reliably.

  The brush roll according to claim 3 is the brush roll according to claim 1 or 2, particularly, wherein the brush portion has a height at which a belt-like body constituting at least one brush body differs from a belt-like body constituting another brush body. In the case of using a brush bristle material having the same material, wire diameter, shape and length, a brush body composed of a belt-like body having a low height is a belt-like body having a high height. Compared with the brush body comprised from this, the hair length of the brush bristle material remove | excluding the height of the strip | belt-shaped body from the bristle length of the brush bristle material becomes long. An increase in the length of the brush bristle material means that the free end side of the brush bristle material becomes longer, and the flexibility of the brush bristle material is improved. On the other hand, a brush body composed of a strip-shaped body having a high height is less than a brush body composed of a strip-shaped body having a low height. The hair length is shortened. When the bristle length of the brush bristle material is shortened, the free end of the brush bristle material is shortened, and the rigidity of the brush bristle material is improved. Therefore, by changing the height of the band-shaped body constituting the brush body, it is possible to give a change in strength to the fluff of the brush bristle material, and the brush bristle material with different contact force and pressing force on the surface to be cleaned. It can be made to contact. For this reason, it is possible to efficiently and reliably remove objects such as foreign matters having various properties attached and deposited on the surface to be cleaned.

A cleaning device according to a fourth aspect includes a brush roll according to any one of the first to third aspects, a driving unit that rotationally drives the brush roll, a cleaning liquid or the like on the brush roll and / or a surface to be cleaned. Since it has a plurality of nozzles for spraying a liquid and a brush mark on which the cleaning mark, that is, the occurrence of cleaning residue is suppressed, is mounted on the surface to be cleaned, excellent cleaning performance can be exhibited.

In the brush roll according to claim 1, the inclination angle with respect to the perpendicular line of the axis of the rotation axis of each brush body is set to 45 ° or less, and one or two brush bodies are spirally formed on the outer periphery of the rotation shaft. Compared to the case where it is formed by being wound, the inclination angle can be set large, so that the brush mark is not left on the surface of the surface to be cleaned, it has excellent cleaning performance, and over a long period of time, Objects such as foreign matters can be efficiently and reliably removed. Moreover, since rotation balance improves, the core blur accompanying rotation can be suppressed.

  Since the brush roll of claim 2 can change the strength of the bristle of the brush bristle material by changing the width of the band-shaped body constituting the brush body, it adheres and accumulates on the surface to be cleaned. Objects such as foreign matters having various properties can be efficiently and reliably removed.

  Since the brush roll according to claim 3 can change the strength of the bristle of the brush bristle material by changing the height of the belt-shaped body constituting the brush body, the brush roll adheres and accumulates on the surface to be cleaned. Objects such as foreign matters having various properties can be efficiently and reliably removed.

The cleaning device according to claim 4 is equipped with a brush roll having excellent cleaning performance, so that a brush mark, that is, a cleaning residue does not occur on the surface to be cleaned, and can exhibit excellent cleaning performance. .

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

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, a 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 diameter D having a hollow portion 9. A brush portion 2 including three brush bodies 4a, 4b, and 4c is attached to the outer periphery of a substantially cylindrical rotating shaft 3 and formed. Three brush body 4a, 4b, 4c, along with being wound spirally on the outer periphery of the rotating shaft 3 at a pitch P _1, respectively, the axis C. of the rotary shaft 3 L. Normal P. L. On the other hand, they are mounted in parallel with an inclination angle θ. The rotating 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 rotating shaft 3, three brush bodies are provided at three positions equally divided on the outer periphery in the vicinity of one end of the rotating shaft 3, as shown in FIG. The starting points S ₁ , S ₂ , S _{3 of} 4 a, 4 b, 4 c are fixed via a fixing part 10 by welding and wound spirally, and the outer circumference equally 3 near the other end of the rotating shaft 3. The end points (not shown) of the three brush bodies 4a, 4b, and 4c are fixed and formed through fixing portions (not shown) by welding.

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

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

In FIG. 2, the brush roll 1 has three brush bodies 4 a, 4 b, and 4 c, each of which includes 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 a brush portion 2 that is wound around the outer periphery in parallel. One brush body 4a is mounted in a spiral shape with a pitch P ₁ in the outer periphery of the rotary shaft 3. 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 rotary shaft 3 with a pitch P ₁ It is installed in a spiral.

Further, each of the brush bodies 4a, 4b, in the width _{W 1} of the strip 6 that constitutes the 4c, with substantially the same dimensions, adjacent brush bodies 4a and the brush body 4b, the brush body 4b and the brush body 4c, width of the gap of the brush body 4c and the brush body 4a is G _1, is formed at substantially the same dimensions. Therefore, the brush body 4a, 4b, 4c pitch _{P 1} of a brush body 4a, 4b, the width _{W 1} of the strip 6 that constitutes the 4c, adjacent brush bodies 4a, 4b, the width _{G 1} of 4c gap Expressed as the sum of That is, the pitch P ₁ = (3W ₁ + 3G ₁ ).

  Next, the axis C. of the rotating shaft 3 of the brush bodies 4a, 4b, 4c. L. Normal P. L. The inclination angle θ with respect to the angle will be described in detail.

  The axis of the rotary shaft 3 C.I. L. Normal P. L. On the other hand, the inclination angle θ of the three brush bodies 4a, 4b, 4c is set to 45 ° or less. The axis C of the rotating shaft 3 of the brush bodies 4a, 4b, 4c. L. Normal P. L. In the case where the inclination angle θ with respect to the width of the belt-like body 6 exceeds 45 °, stress at the time when the brush bristle material 8 comes into contact with the surface to be cleaned tends to concentrate on the side edge of the belt-like body 6. The brush bristle material 8 has fuzz, and fatigue refraction occurs from the portion with the fuzz, and the brush bristle material 8 is broken. Therefore, the cleaning performance of the brush roll 1 deteriorates and the durability decreases.

  More preferably, the inclination angle θ is set at 4 ° or more and 30 ° or less. When the angle is less than 4 °, the object such as the foreign matter removed from the surface to be cleaned due to the inclination angle θ is too small to move in the longitudinal direction of the rotating shaft 3, and the object such as the foreign matter is efficiently and reliably removed from the brush roll 1. Difficult to exclude outside. On the other hand, when the inclination angle θ exceeds 30 °, the brush bristle material 8 makes contact with the surface to be cleaned while ensuring a wider contact area, but the frictional resistance against the surface to be cleaned of the brush bristle material 8 increases. The wear of the brush bristle material 8 is promoted.

The axis C of the rotating shaft 3 of the brush bodies 4a, 4b, 4c. L. Normal P. L. The inclination angle θ is defined by the pitch P ₁ of the brush bodies 4a, 4b, and 4c and the diameter D of the rotating shaft 3, and varies depending on the numerical value. That is, the brush member 4a, 4b, the larger the value of the pitch _{P 1} of 4c, as the value of the diameter D of the rotary shaft 3 is small, the brush body 4a, 4b, 4c of the axis C. of the rotary shaft 3 L. Normal P. L. The inclination angle θ with respect to the angle increases. The above is described using trigonometric functions and limit expressions.

The value of the diameter D of the rotary shaft 3 is fixed (constant), when the brush body 4a, 4b, the value of the pitch P ₁ of the 4c is changed (variable) can be expressed by the following equation.

The sine (sin θ) approaches _{1 as} the value of the pitch P1 of the brush bodies 4a, 4b, 4c approaches infinity, that is, increases. When sin θ = 1, the value of the inclination angle θ is 90 ° at the maximum, and the above formula shows that the rotation of the brush bodies 4a, 4b, 4c increases as the value of the pitch P ₁ of the brush bodies 4a, 4b, 4c increases. Axis center of shaft 3 L. Normal P. L. This indicates that the inclination angle θ with respect to the angle increases.

On the other hand, a brush body 4a, 4b, the value of the pitch P ₁ of 4c constant (constant), when the value of the diameter D of the rotary shaft 3 is changed (variable) can be expressed by the following equation.

  The cosine (cos θ) approaches 0 as the value of the diameter D of the rotary shaft 3 approaches 0, that is, decreases. In the case of cos θ = 0, the value of the inclination angle θ is 90 ° at the maximum, and in the above formula, the axis of the rotating shaft 3 of the brush bodies 4a, 4b, 4c decreases as the value of the diameter D of the rotating shaft 3 decreases. C. L. Normal P. L. This indicates that the inclination angle θ with respect to the angle increases.

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

  First, as shown in FIG. 3, a plurality of long brush bristle materials 8 having a substantially round cross section are 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, wire diameter, shape, hair length, 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 11 so that the substantially central portion of the brush bristle material 8 in the longitudinal direction overlaps the upper portion of the belt-like body 6. Next, using the vertical roll 12, 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, using the horizontal rolls 13 and 13 installed on both sides of the belt-like body 6, the belt-like body 6 is caulked from both sides. As a result, as shown in FIG. 1C, a brush body comprising a long channel brush 5 in which a 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. 4a, 4b, 4c are formed.

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 rotary shaft 3 is fixed through the fixing portion 10 by welding , as in FIG. 1 (a), is mounted wound helically with a pitch P ₁ in the outer periphery of the rotary 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 rotating shaft 3 via a fixing part (not shown) by welding. Similarly, the other two brushes member 4b, and 4c is an outer periphery of the rotating shaft 3, while being mounted between the pitch P ₁ of the brush body 4a, the other two brushes member 4b, 4c even pitch P ₁ Is wound around the outer periphery of the rotating shaft 3, and the brush points 2 are rotated by fixing the starting points S ₂ and S ₃ and the unillustrated end point near the both ends of the rotating shaft 3 via the fixing portions 10 by welding. The brush roll 1 formed on the outer periphery of the shaft 3 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 rotating shaft 3. Accordingly, the brush roll 1 has only one brush body 4a or two brush bodies 4a and 4b spirally wound around the outer periphery of the rotary shaft 3 as compared with each brush body 4a. 4b, 4c. L. Normal P. L. The inclination angle θ 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 has only one brush body 4a or two brush bodies 4a and 4b spirally wound around the outer periphery of the rotary shaft 3 as compared with each brush body 4a. 4b, 4c are axes C. L. Normal P. L. On the other hand, since the inclination angle θ is set to be large, even if an object such as a foreign matter removed from the surface to be cleaned by the brush bristle material 8 is caught between the brush bristle material 8, It is difficult to fall on the surface of the surface to be cleaned with rotation. For this reason, reattachment of an object such as a foreign object to the surface to be cleaned is prevented.

  Further, the brush roll 1 has an axial center C.V. of the rotating shaft 3 of the brush bodies 4a, 4b, 4c. L. Normal P. L. Since the inclination angle θ is set to 45 ° or less, the stress at the time when the brush bristle material 8 comes into contact with the surface to be cleaned is less likely to concentrate on the side edge of the belt-like body 6. Since wrinkles and hair breakage hardly occur, excellent cleaning performance is exhibited over a long period of time.

  Further, the brush roll 1 rotates to move objects such as foreign matters along the inclination angle θ of the brush bodies 4a, 4b, 4c, and excludes the objects outside the brush roll 1, but the brush bodies 4a, 4b 4c is formed by being spirally wound around the outer periphery of the rotating shaft 3 in the same direction, so that it is not limited to the rotating direction of the brush roll 1, and either one end of the brush roll 1 The object such as foreign matter is excluded from the outside.

Furthermore, since the start points S ₁ , S ₂ , S ₃ and the end points of the brush bodies 4 a, 4 b, 4 c are formed at equal locations on the outer periphery of the rotating shaft 3 via the fixing portions 10 by welding, the brush roll The rotation balance of 1 is improved, and the core blur accompanying rotation is suppressed.
