Description

  The present invention relates to a brush roll that performs cleaning, cleaning, polishing, surface treatment, etc. 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, and a cleaning equipped with the brush roll It relates to the device.

  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. There is a roll brush (Patent Document 1) characterized in that a locking portion for achieving the above is provided.

  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 arranged at a substantially right angle to the axial direction of the roll, the inclination angle of the coil brush with respect to the perpendicular to the axial center of the roll is extremely small, and the tip of the brush material is cleaned as the roll brush rotates. Since point contact is made at a substantially right angle to the surface, a gap portion that does not contact the surface to be cleaned is formed between the brush materials, and a brush mark is generated on the surface to be cleaned. Since the brush mark is a cleaning residue on the surface to be cleaned, the roll brush cannot clean the surface to be cleaned uniformly, and there is a problem that the cleaning performance is poor.

  In addition, the channel brush has a coil brush formed by close spiral winding, and no gap is formed between adjacent coil brushes, so that a foreign object or other object removed from the surface to be cleaned is captured by the brush material. As the roll brush rotates, the object is not released to the outside of the roll brush through the gap formed between the pitches of the coil brushes, and thus remains captured by the brush material. Then, when the roll brush rotates and the brush material comes into contact with the surface to be cleaned, the object captured by the brush material falls off on the surface to be cleaned, and foreign matter or the like is reattached to the surface to be cleaned. Also, the roll brush has a problem that the removal performance of objects such as foreign matters is inferior.

  In order to solve the problems described above, a cleaning nozzle is provided on the inlet side, and a brush having a predetermined width is provided on the outer peripheral surface of the roll body at a predetermined pitch symmetrically with respect to the symmetry axis set at the center of the entire length of the roll body. And the brush roll (patent document 2) of the steel plate washing machine characterized by winding in the spiral direction which can send an object toward the end of a roll main body from the said symmetrical axis is devised.

  The brush roll of patent document 2 is explained in full detail using FIG.6 and FIG.7. 6A is a partial front view of a brush roll in a conventional example, FIG. 6B is a partial cross-sectional view of the brush roll in the conventional example, and FIG. 7 is a cleaning device on which the brush roll of the conventional example is mounted. It is a perspective view.

6 (a) and 6 (b), a conventional brush roll 41 includes a hollow roll body 43 having a diameter D and a brush 44 spirally wound around the outer periphery of the roll body 43. ing. The brush 44 has a long shape in which a wire 48 is sandwiched between a base material 46 having a substantially U-shaped cross section and a core wire 47 having a substantially round cross section. L. Symmetrically relative to the symmetry axis 40 which is set substantially in the center direction, and, from the axis of symmetry 40 towards the respective ends of the roll body 43 in one by one spiral, provided to be wound with a pitch P ₂ ing. S is a starting point when the brush 44 is wound around the roll body 43. Further, the pitch P ₂ of the brush 44 is expressed as the sum of the width W of the base material 46 constituting the brush 44 and the gap G between the adjacent brushes 44. That is, the pitch P ₂ = W + G.

  Next, the cleaning of the blank material 57 by the brush roll 41 will be described with reference to FIG. The brush roll 41 is installed in a steel plate washer 50, and the blank material 57 is a material that requires cleaning such as a steel plate before press working, so that the tip of the brush 44 is in sliding contact with the surface of the blank material 57. The position of the brush roll 41 is set. An object 59 such as a foreign substance made of resin, iron powder, dust or the like adheres to the surface of the substrate 58 of the blank material 57.

  Then, while feeding the blank material 57 in the direction of the white arrow by the moving means (not shown), the driving means 54 causes the brush roll 41 to rotate counterclockwise as indicated by the solid arrow, and the peripheral speed of the tip of the brush 44 is The rotation speed is set to be larger than the moving speed of the blank material 57, and at the same time, the cleaning liquid is sprayed from the cleaning nozzle 55 to the rotation inlet side of the brush roll 41.

By doing in this way, the object 59 adhering to the surface of the base material 58 of the blank material 57 in the part which the brush 44 contact | abutted with the washing | cleaning liquid and the axial center C.P. L. Component force generated by the rotation of the brush roll 41 from the symmetry axis 40 set at the substantially central portion of the direction toward the left and right ends. F. Moved and removed. In addition, since the brush roll 41 has a gap G between the adjacent brushes 44, the object 59 captured by the wire 48 is moved to both the brush roll 41 via the gap G as the roll body 43 rotates. It is discharged to the outside from the end portion. Therefore, the brush roll 41 has an excellent removal performance of the target object 59 such as foreign matter.
JP 2001-346629 A JP 2004-137573 A

However, in the configuration of the conventional brush roll 41 described above, the brush 44 is located on the left and right sides of the symmetrical axis 40 set at the substantially central portion of the roll body 43 as shown in FIGS. 6 (a), 6 (b), and 7. Since only one of them is arranged in a spiral shape toward the end of each, the axis C. of the roll main body 43 of the brush 44 is arranged. L. Normal P. L. The angle of inclination θ ₂ is small, and, like the roll brush shown in Patent Document 1, the tip of the wire rod 48 is in point contact with the blank material 57, and a gap portion that does not contact the blank material 57 occurs between the wire rods 48. Brush marks are generated on the material 57. The brush mark becomes a cleaning residue of the streaky object 59 with respect to the base 58 of the blank material 57 on the downstream side of the brush roll 41 of FIG. Further, since the wire 48 is in point contact with the blank material 57, the contact force of the wire 48 with respect to the blank material 57 is weak, and the brush roll 41 cannot clean the blank material 57 uniformly, and the cleaning performance is inferior. Had problems.

To solve this problem, to widen the gap G between adjacent brush 44, by increasing the pitch P _2, the axis C. roll body 43 L. Normal P. L. Set to a large inclination angle theta ₂ against, although the wire 48 can be considered a method of contact line to secure large contact area against the blank 57, Then, the brush roll 41, the brush 44 is substantially central portion of the roll body 43 From the symmetrical axis 40 set to, only one of them is arranged in a spiral shape toward the left and right end portions, so that the gap G between the adjacent brushes 44 becomes larger. As a result, a portion that does not come into contact with the blank material 57 is generated, and a brush mark is generated on the blank material 57 as well. Therefore, as in the conventional brush roll 41, in the structure in which only one brush 44 is arranged spirally toward the left and right end portions from the symmetry axis 40 set at the substantially central portion of the roll body 43. , to widen the gaps G between adjacent brushes 44, with a larger pitch _{P 2,} the axis C. roll body 43 L. Normal P. L. Be set to a large inclination angle theta ₂ against, it is not conducive to the improvement of cleaning performance.

  Also, the blank material 57 is pressed by a mold after being washed and formed as a panel component constituting a car body of an automobile. As described above, the object such as foreign matter remaining on the surface of the blank material 57 as a brush mark is obtained. The object 59 generates a press mark on the panel component when the blank material 57 is pressed with a mold or the like. That is, the surface of the blank material 57 on which the object 59 remains is recessed by being pressed with a mold or the like, and the back surface of the blank material 57 is convex to form a press mark. As described above, the panel parts with the press marks are of poor quality and cannot be sent to the next welding process or painting process, and are discarded. Therefore, the steel plate cleaning machine 50 has a problem that the quality of the blank material 57 cannot be improved.

  The present invention solves the above-mentioned conventional problems, and has excellent cleaning performance that does not cause cleaning residue like a brush mark on the surface to be cleaned, and high efficiency of efficiently and reliably eliminating objects such as foreign matters. It is an object of the present invention to provide a brush roll having removal performance, and a cleaning device equipped with the brush roll to improve the quality of the surface to be cleaned.

  In order to solve the above-mentioned conventional problems, the brush roll of claim 1 performs cleaning, cleaning, polishing, surface treatment, etc. of a surface to be cleaned made of a steel plate, a non-ferrous metal plate, a resin plate, a film-like resin composition, or the like. In the brush roll to be performed, the brush roll has a substantially rod-shaped or cylindrical rotating shaft and a brush portion wound spirally around the outer periphery of the rotating shaft, and the brush portion is a belt-like body having a substantially U-shaped cross section. And a brush body formed of a channel brush composed of a brush bristle material sandwiched together with a core wire by the belt-like body is formed by being spirally wound around the outer periphery of the rotating shaft, Around the axis of symmetry set as a part of the axial direction of the axis of rotation, the angle of inclination at the time of winding is wound around the axis of rotation to be symmetric, and a plurality of them are provided in parallel on the left and right sides, Around the axis of rotation The brush roll is formed by being fixed by a fixing means, and the brush roll is wound around the outer periphery of the rotating shaft in a spiral manner with each brush body facing the left and right ends of the rotating shaft around the symmetry axis. In addition, one or more other brush bodies are arranged between the pitches of adjacent brush bodies. Therefore, the brush roll is formed in such a manner that only one brush body is spirally wound around the outer periphery of the rotating shaft toward the left and right ends of the rotating shaft around the symmetry axis. The inclination angle with respect to the perpendicular line of the axis of rotation of each brush body can be set large. Therefore, with the rotation of the brush roll, the brush bristle material ensures a large contact area against the surface to be cleaned and comes into contact with the line, so there is no gap where the brush bristle material does not come into contact with the surface to be cleaned. Generation of marks is suppressed. In addition, since the brush bristle material comes into contact with the surface to be cleaned by line contact, the contact force of the brush bristle material against the surface to be cleaned is strong, and no cleaning residue is generated on the surface to be cleaned. Clean the surface evenly.

  In addition, the brush roll can be widened in the axial direction of the rotation axis by increasing the inclination angle of the brush body as compared with the case where only one brush body is provided on each of the left and right sides around the axis of symmetry. , Due to the dam effect, the component force generated from the symmetry axis toward both ends of the rotating shaft as the rotating shaft rotates due to the rotation of the rotating shaft, while the cleaning liquid is effectively dammed up By washing with the cleaning liquid to the outside of the surface to be cleaned, it is removed.

  The brush roll according to claim 2 is the brush roll according to claim 1, wherein the symmetry axis is set at a substantially central portion in the axial direction of the rotation shaft. Since the moving distance of the object scraped by the component force from the head toward the end becomes equal, the cleaning effect is not uneven. Therefore, the cleaning performance is greatly improved.

  The brush roll according to claim 3 is the brush roll according to claim 1 or 2, particularly, in which the belt portion constituting at least one brush body has a width different from the belt-like body constituting the other brush body. When the brush material of the same material, wire diameter, shape and bristle length is used, the brush body composed of the band-shaped body having a small width is composed of the band-shaped body having a large width. Compared with the brush 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 accurately removed.

  The brush roll according to claim 4 is a brush roll according to claims 1 to 3, in particular, the brush portion has a height at which a belt-like body constituting at least one brush body is different 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 means that the free end of the brush bristle becomes longer, and the flexibility of the brush bristle improves. 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. That the bristle length of the brush bristle material is shortened means that the free end side of the brush bristle material is short, 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 accurately remove objects such as foreign matters having various properties attached and deposited on the surface to be cleaned.

  The brush roll according to claim 5 is the brush roll according to any one of claims 1 to 4, wherein the brush portion has a gap between adjacent brush bodies, and the gap is set to be equal to or less than the minimum width of the belt-like body. In some cases, an object such as a foreign substance captured by the brush bristle material is discharged to the outside from both ends of the brush roll through a gap as the rotating shaft rotates.

  Further, since the gap between adjacent brush bodies is set to be equal to or less than the minimum width of the belt-like body, there is no occurrence of a portion where the brush bristle material does not contact the surface to be cleaned, and the brush mark on the surface to be cleaned, that is, the cleaning There will be no rest.

  The brush roll according to claim 6 is the brush roll according to any one of claims 1 to 5, particularly, wherein the brush portion is formed by fixing the starting point and the ending point of each brush body at equal intervals on the outer periphery of the rotating shaft by fixing means. In the brush roll, since the occurrence of the core blur accompanying the rotation of the rotation shaft is suppressed and the stable rotation is maintained, excellent cleaning performance is exhibited over a long period of time.

  The brush roll according to claim 7 is the brush roll according to any one of claims 1 to 6, wherein the brush body is formed so as to have an inclination angle of 45 ° or less with respect to the vertical line of the axis of the rotation shaft. When the angle of inclination with respect to the vertical line of the axis of the rotation axis 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 band. The bristle is attached to the brush bristle at the portion, fatigue refraction occurs from the part with the furrow, 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. The stress at the time is difficult to concentrate, and the bristle of the brush bristle material is not likely to be broken, so that the durability is improved and excellent cleaning performance is exhibited over a long period of time.

  A cleaning apparatus according to an eighth aspect of the present invention includes a brush roll according to any one of the first to seventh 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. It has a plurality of nozzles that spray liquid, and a brush mark on the surface to be cleaned, that is, a brush roll that does not generate cleaning residue is mounted, so that it exhibits excellent cleaning performance and the surface to be cleaned The quality can be improved.

  Since the brush roll of claim 1 can set a large inclination angle with respect to the perpendicular to the axis of the rotation axis 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. At the same time, an object such as a foreign object can be efficiently and reliably removed from the symmetry axis toward both ends of the rotation axis.

  In the brush roll of claim 2, the occurrence of uneven cleaning is suppressed, and the cleaning performance is greatly improved.

  Since the brush roll according to claim 3 can change the strength of the bristle of the brush bristle material by changing the width of the belt-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 accurately removed.

  The brush roll according to claim 4 is capable of imparting a change in strength to the bristle of the brush bristle material by changing the height of the belt-shaped body constituting the brush body, so that it adheres and accumulates on the surface to be cleaned. It is possible to accurately remove objects such as foreign matters having various properties.

  According to a fifth aspect of the present invention, there is provided the brush roll according to the present invention, in which a brush mark is not generated on the surface to be cleaned, and an object such as a foreign matter captured by the brush bristle material is brushed through a gap formed between adjacent brush bodies. Since it can discharge | release to the exterior of a roll, the cleaning performance and the removal performance of a target object improve significantly.

  Since the brush roll of Claim 6 improves rotation balance, it can suppress the core blur accompanying rotation of a rotating shaft.

  Since the brush roll of Claim 7 suppresses generation | occurrence | production of the hair breakage of a brush bristle material, while improving durability of a brush roll, it can exhibit the outstanding cleaning performance over a long period of time.

  Since the cleaning apparatus of claim 8 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. At the same time, the quality of the surface to be cleaned can be improved.

  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, 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. Brush portions 2a and 2b composed of two brush bodies 4a and 4b are mounted on the outer periphery of the substantially cylindrical rotating shaft 3. The brush portions 2a and 2b are arranged on the axis C.V. L. The axis of symmetry 10 set at a substantially central portion of the direction, the two brush body 4a on the left and right, 4b, together with being wound spirally on the outer periphery of the rotating shaft 3 at a pitch P _1, The axis of the rotary shaft 3 C.I. L. Normal P. L. The angle of inclination θ ₁ is formed in parallel so as to be symmetric about the symmetry axis 10 during winding. The rotating shaft 3 may be a solid substantially rod shape.

In FIG. 1C, brush bodies 4a and 4b are made of a strip-like body 6 having a long U-shaped cross section made of a metal material such as iron, aluminum or stainless steel, and a metal material such as iron, aluminum or 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. When the brush bodies 4a and 4b are mounted on the outer periphery of the rotating shaft 3, two brush bodies 4a are respectively provided at two positions equally divided on the outer periphery of the rotating shaft 3 in the vicinity of the symmetry shaft 10 as shown in FIG. 4b start points S ₁ and S ₂ are fixed through a fixing part 11 by welding and wound spirally, and as shown in FIG. 1B, the outer periphery in the vicinity of both ends of the rotary shaft 3 and the like. The end points E ₁ and E _{2 of the two} brush bodies 4a and 4b are fixed to the two minute portions via the fixing portions 11 by welding to form the brush portions 2a and 2b.

  In the present embodiment, two brush bodies 4a and 4b are provided on the outer periphery of the rotating shaft 3 around the symmetry axis 10 toward the left and right ends of the rotating shaft 3, respectively. Or more than that. Further, the fixing means for the outer periphery of the rotating shaft 3 of the brush bodies 4a, 4b may form the fixing portion 11 by screwing, riveting or the like using a locking tool in addition to welding. Furthermore, the setting position of the symmetry axis 10 is not limited to the substantially central portion of the rotating shaft 3 and can be set to an arbitrary position of the rotating shaft 3 according to the purpose of use.

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

In FIG. 2, the brush roll 1 has two brush bodies 4 a and 4 b composed of a channel brush 5 in which a brush bristle material 8 is sandwiched between a belt-like body 6 and a core wire 7, on the outer periphery of a rotary shaft 3 having a hollow portion 9. It is wound and mounted in parallel, and is formed as brush portions 2a and 2b. 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, along with other brush body 4b are parallel, the other brush body 4b be mounted is wound spirally on the outer periphery of the rotary shaft 3 with a pitch P ₁ Yes.

Moreover, the width | variety of the strip | belt-shaped body 6 which comprises each brush body 4a, 4b is W, and the clearance gap G is formed between the adjacent brush body 4a and the brush body 4b. Therefore, the brush body 4a, the pitch _{P 1} of 4b, the brush body 4a, the width W of the strip 6 that constitutes the 4b, expressed as the sum of the brush body 4a adjacent, 4b of the gap G. That is, the pitch P ₁ = 2W + 2G = 2 (W + G). The gap G is set to be equal to or less than the width W of the belt-like body 6.

Next, the axial center C. of the rotating shaft 3 of the brush bodies 4a, 4b. L. Normal P. L. It will be described in detail inclination angle θ ₁ against.

The axis of the rotary shaft 3 C.I. L. Normal P. L. Against, the inclination angle theta ₁ which left and right two brush bodies 4a, 4b has around the symmetry axis 10 is set at 45 ° or less. The axis C of the rotating shaft 3 of the brush bodies 4a and 4b. L. Normal P. L. When the angle of inclination θ ₁ to the angle exceeds 45 °, the 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 band 6. As a result, fluff is attached to the brush bristle material 8, fatigue refraction occurs from the part with the furrow, and the brush bristle material 8 is broken. Therefore, the cleaning performance of the brush roll 1 deteriorates and the durability decreases.

Further preferably, the inclination angle theta ₁ is desirably set at 4 ° or 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 ₁ is too small, the axis C.C. L. It is difficult to move left and right in the direction, and it is difficult to efficiently and reliably exclude objects such as foreign matters outside the brush roll 1. On the other hand, if the inclination angle theta ₁ is greater than 30 °, the brush bristles 8 the contact area against the cleaning surface, although the contact to secure wider, with frictional resistance to the cleaned surface of the brush bristles 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 and 4b. L. Normal P. L. Inclination angle theta ₁ towards the brush body 4a, is defined by the diameter D of the pitch P _1, and the rotation shaft 3 of 4b, varies with the number. In other words, the brush body 4a, the larger the value of the pitch _{P 1} of 4b, as the value of the diameter D of the rotary shaft 3 is small, the brush body 4a, 4b of the axial center C. of the rotary shaft 3 L. Normal P. L. Inclination angle theta ₁ towards the greater. 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, the value of the pitch P ₁ of the 4b is changed (variable) can be expressed by the following equation.

The sine (sin θ ₁ ) approaches _{1 as} the value of the pitch P ₁ of the brush bodies 4a, 4b approaches infinity, that is, increases. When sin θ ₁ = 1, the value of the inclination angle θ ₁ is 90 ° at the maximum, and the above formula shows that the rotation axis 3 of the brush bodies 4a and 4b increases as the value of the pitch P ₁ of the brush bodies 4a and 4b increases. Axis of C. L. Normal P. L. Inclination angle theta ₁ is indicates that the increase against.

However, the conventional brush roll 41 shown in Figure 6, the diameter D of the roll body 43 is substantially the same as the diameter D of the rotating shaft 3 in the brush roll 1 of the present invention, the pitch P ₂ of the brush 44 W + G The pitch P ₁ = 2 (W + G) of the brush bodies 4a and 4b in the brush roll 1 of the present invention is half the length. Accordingly, the brush roll 1 of the present invention, the brush body 4a, the pitch P ₁ of 4b is because it is twice the length of the pitch P ₂ of the brush 44 of the conventional brush roll 41, the brush roll 1 of the present invention inclination angle theta ₁ with the can be set larger than the inclination angle theta ₂ with a conventional brush roll 41.

On the other hand, a brush body 4a, the value of the pitch P ₁ of 4b 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 ₁ ) approaches 0 as the value of the diameter D of the rotating shaft 3 approaches 0, that is, decreases. When cos θ ₁ = 0, the value of the inclination angle θ ₁ is 90 ° at the maximum, and the above formula shows that the smaller the value of the diameter D of the rotating shaft 3, the smaller the axis of the rotating shaft 3 of the brush bodies 4a and 4b. C. L. Normal P. L. Inclination angle theta ₁ is indicates that the increase against.

  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 may be made of any 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, and may be mixed. 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 14 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 and 4b are formed.

Next, as shown in FIG. L. In the vicinity of the axis of symmetry 10 set at a substantially central portion of the direction, one end of one of the brush body 4a, i.e. the start point S ₁ is fixed via the fixing unit 11 by welding, to the outer periphery of the rotary shaft 3 It is attached is wound helically with a pitch P _1. Then, as in FIG. 1 (b), the other end portion of the brush body 4a, i.e. the end point E ₁ is, near one end of the rotary shaft 3 is fixed via the fixing unit 11 by welding. Similarly, the other brush body 4b is the outer periphery of the rotary shaft 3, while being mounted between the pitch P ₁ of the brush body 4a, the other brush body 4b be wound around the outer periphery of the rotary shaft 3 with a pitch P ₁ The starting point S ₂ and the end point E ₂ are fixed to the outer periphery of the rotating shaft 3 via the fixing portion 11 by welding, so that one brush portion 2 a is formed on the outer periphery of the rotating shaft 3. Similarly, the brush bodies 4a and 4b are wound from the symmetry axis 10 toward the other end of the rotary shaft 3, whereby the other brush part 2b is formed, and the brush roll 1 is formed as shown in FIG. ) And 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, one brush body 4 a is spirally wound around the outer periphery of the rotating shaft 3 toward the left and right ends of the rotating shaft 3 around the symmetry axis 10, and adjacent brush bodies between the pitch P ₁ of 4a, the other brush body 4b are arranged. Therefore, the brush roll 1 is formed by spirally winding only one brush body 4a around the outer periphery of the rotating shaft 3 toward the left and right ends of the rotating shaft 3 around the symmetry axis 10. Compared with a case where the axis C. of the rotating shaft 3 of each brush body 4a, 4b is C.I. L. Normal P. L. The inclination angle theta ₁ towards, can be set larger. Therefore, as the brush roll 1 rotates, the brush bristle material 8 has a wide contact area against the surface to be cleaned and abuts by line contact, so there is a gap portion where the brush bristle material 8 does not abut on the surface to be cleaned. This eliminates the occurrence of brush marks. Further, since the brush bristle material 8 comes into contact with the surface to be cleaned by line contact, the contact force against the surface to be cleaned of the brush bristle material 8 is strong, and no cleaning residue is generated on the surface to be cleaned. Cleans the surface to be cleaned evenly.

Brush roll 1, the axis of symmetry 10, as compared with the case of providing only one brush body 4a to the left and right respectively, the rotary brush member 4a, and 4b brush bodies 4a, 4b the inclination angle theta ₁ of increased to Axis center of shaft 3 L. Because of the dam effect, the dam effect effectively dams the cleaning liquid, and the foreign matter adhered to and accumulated on the surface to be cleaned is moved from the symmetry axis 10 to the rotation axis 3 along with the rotation of the rotation axis 3. By the component force generated toward both ends, the cleaning liquid is washed out to the outside of the surface to be cleaned and removed.

  The brush roll 1 has an axis C.C. L. Since it is set at the substantially central portion of the direction, the movement distance of the object scraped by the component force from the substantially central portion of the rotating shaft 3 toward the end is equal between the left and right brush portions 2a and 2b. Therefore, unevenness in the cleaning effect does not occur. Therefore, the cleaning performance is greatly improved.

  Since the brush portions 2a and 2b have a gap G between the adjacent brush bodies 4a and 4b, and the gap G is set to be equal to or less than the width W of the belt-like body 6, it is captured by the brush bristle material 8. An object such as a foreign object is discharged to the outside from both ends of the brush roll 1 through the gap G as the rotating shaft 3 rotates.

Brush unit 2a, 2b is a brush body 4a, the starting point _S 1, _{S 2} of 4b, and the end point _E 1, _{E 2,} are formed through the fixing portion 11 by welding equally portion of the outer periphery of the rotary shaft 3 Therefore, the rotation balance of the brush roll 1 is improved, and the core blur accompanying rotation of the rotating shaft 3 is suppressed.

The brush roll 1 has an axis C.C. of the rotation shaft 3 of the brush bodies 4a and 4b. L. Normal P. L. The inclination angle theta ₁ is set at 45 ° or less against, the side edges of the strip 6, the brush bristles 8 are hardly concentrated stress when in contact with the cleaned surface, the brush hairs 8 Since it is difficult for hair follicles and hair breakage to occur, durability is improved and excellent cleaning performance is exhibited over a long period of time.

  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 an example, a substantially central portion in the longitudinal direction of a long brush bristle material 8 made of 66 nylon having a wire diameter of 0.4 mm is sandwiched between a long belt-like body 6 made of iron and a core wire 7. At the same time, the brush bodies 4a and 4b composed of the long channel brush 5 were formed. The hair length of the folded brush bristle material 8 was set to 50 mm. Next, the axis C. of the substantially cylindrical rotating shaft 3 made of iron having a diameter of 200 mm and a length of 360 mm is provided. L. A symmetric axis 10 is set at a substantially central portion of the direction, and two brush bodies 4a and 4b are respectively directed from the symmetric axis 10 to both ends of the rotating shaft 3, and an interval between adjacent gaps G is 2 mm. body 4a, the pitch _{P 1} of 4b is set to 20mm winding spirally to form a brush portion 2a, a 2b. The width W of the belt-like body 6 is 8 mm, and the axis C.C of the rotating shaft 3 of the brush bodies 4a and 4b. L. Normal P. L. The inclination angle θ ₁ with respect to is formed at about 5 °. In addition, the starting points S ₁ and S ₂ and the end points E ₁ and E ₂ of the brush bodies 4a and 4b were fixed to the outer periphery of the rotating shaft 3 at two equal portions via fixing portions 11 by welding. Then, two brush rolls of the example were manufactured according to the above procedure.

As a comparative example, the axial center C.V. L. A symmetrical axis 10 is set at a substantially central portion in the direction, and two brush rolls 1 each having brush portions 2a and 2b formed by one brush body 4a from the symmetrical axis 10 toward both ends of the rotating shaft 3 are provided. Produced. Brush roll 1 of the comparative example, the outer periphery of the rotating shaft 3, the brush body 4a, to set the distance between the adjacent gap G 2 mm, the width W of the strip 6 8 mm, the pitch _{P 1} of the brush body 4a to 10mm And spirally formed. Other conditions, such as the dimension of the rotating shaft 3, are the same conditions as the brush roll 1 of an Example. In addition, the axis C. of the rotating shaft 3 of the brush body 4a. L. Normal P. L. The inclination angle θ ₁ with respect to was formed at about 2 °.

  Next, each of the two example and comparative example brush rolls configured as described above are attached to a through-plate testing machine in a pair of upper and lower pairs, and rotated at a constant rotational speed of 150 rpm. A hot-dip galvanized steel sheet coated with Komyotan (trilead tetroxide), which becomes artificial dirt, is prepared, and the tips of the brush portions 2a and 2b attached to the outer periphery of the rotating shaft 3 rotating at the rotation speed are drawn. The hot-dip galvanized steel sheet is set so that its dirty surface faces the rotating shaft 3 at a position close to the rotating shaft 3 by 2 mm from the virtual circle, and cleaning water is sprayed at a spraying amount of 7 L per minute. Meanwhile, the hot-dip galvanized steel sheet is passed through a pair of upper and lower brush rolls 1 at a peripheral speed of 100 mpm, and the brush parts 2a and 2b are brought into contact with the dirt surface of the steel sheet to thereby remove the dirt on the steel sheet. It was removed.

And the brightness of the part which removed the stain | pollution | contamination by the brush parts 2a and 2b 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 less than +5

Moreover, the brush mark of the steel plate after the test, that is, the presence or absence of the 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 example has the axis C.V. of the rotating shaft 3 of each brush body 4a, 4b. L. Normal P. L. Since a large inclination angle theta _1, with the rotation of the rotary shaft 3, since the brush hairs 8 abuts at widely secured to line contact the contact area against the steel sheet, the brush bristles 8 on the steel sheet does not contact gap against Generation of a portion, that is, a brush mark is suppressed. Further, since the brush bristle material 8 is brought into contact with the steel plate in a line contact, the contact force of the brush bristle material 8 against the steel plate is strong, and no cleaning residue is generated on the steel plate and has excellent cleaning performance. .

On the other hand, the brush roll 1 of the comparative example has an axial center C.V. of the rotating shaft 3 of the brush body 4a. L. Normal P. L. Since the inclination angle θ ₁ is extremely small, the contact area of the brush bristle material 8 with the steel plate accompanying the rotation of the rotary shaft 3 is also very narrow, and the point of contact with the steel plate does not contact the steel plate with the brush bristle material 8. A gap portion, that is, a brush mark is generated. Further, since the brush bristle material 8 abuts on the steel plate by point contact, the abutment force of the brush bristle material 8 against the steel plate is weak, cleaning residue is generated on the steel plate, and the cleaning performance is very poor.
