Description

  The present invention relates to a brush roll used for cleaning, grinding, polishing, surface treatment, cleaning, deburring of steel plates, non-ferrous metal plates, resin plates, film-like compositions, glass plates, etc. The present invention relates to a brush roll having a hair material having excellent weather resistance as a constituent element.

  In general, in order to remove dust from the workpiece and process the surface, the brush roll is brought into contact with the workpiece surface to obtain a predetermined cleanliness or surface processing accuracy. In the dust removal and surface processing as described above, a bending load due to contact is repeatedly applied to the bristle material of the brush roll every rotation of the brush roll. Furthermore, when it reaches a certain level of use, the recovery of the bristle material itself declines, causing collapse and bending, and there is a problem that the bedclothes are permanently generated and cannot be used. In order to overcome the problems as described above, with regard to the conventional brush roll, the hair material used is a polyamide-based resin fiber exhibiting excellent bending resistance due to hydrogen bonding of the amide group, particularly nylon 6 or nylon 66. It is used as a lot.

  In addition, various improvements have been made for brush rolls according to the purpose of use. For example, brush rolls that can be used for polishing and polishing thick plates and thin plates in a steel plate production line, and the brush bristle material is polyamide filament yarn. The surface is covered with a film of halogenated polymer compound, or a bundle of polyamide filament yarns is spirally wound with a thin filament of synthetic fiber or covered with a braid-like structure, and the surface is covered with a film of halogenated polymer compound. Japanese Patent Application Laid-Open No. 8-168968 discloses a technique that has the feature of preventing the brush bristle material from being reduced by absorbing or absorbing water under spraying with water by covering or impregnating it. It has been done.

  For example, the conventional brush roll bristle material is often used as a bristle material, such as polyamide resin fiber, particularly nylon 6 or nylon 66, which exhibits excellent bending resistance due to amide group hydrogen bonding as described above. Since the hair material has an amide group, it has high moisture absorption and water absorption, has a problem that it swells and weakens significantly in water droplets and water, and also has a problem of being attacked by acid. Moreover, although the said bristle material is excellent in bending resistance, it has the subject which has not yet overcome generation | occurrence | production of the litter by repetition of a bending load.

  In the technique disclosed in JP-A-8-168968, the production process is complicated and the production cost is increased, and the halogenated polymer compound is polyvinylidene chloride, polytrifluoroethylene chloride, fluorinated compound. Film processing or impregnation processing is performed using a chloride compound such as vinylidene or a fluorinated polymer compound. Therefore, the chlorinated compound has a problem that toxic gas is generated during incineration. Further, the fluorinated polymer compound has a problem that the material itself is expensive.

  JP-A-8-168968

  Therefore, the present invention has been made in view of the above-described conventional problems, and imparts a strong bending recovery force to the brush bristle material configured in the brush roll, and makes the hair material itself bedding due to repeated bending loads. An object of the present invention is to provide a brush roll that is difficult to cause, prevents swelling due to water absorption, eliminates the reduction in stiffness of the brush bristle material, and has acid resistance.

  In order to solve the above-mentioned problems, the present invention uses polytrimethylene terephthalate fiber or a different kind of fiber from polytrimethylene terephthalate fiber in the brush bristle material formed in the brush roll.

  The second problem-solving means is that the bristle material constituting the brush roll is formed by alternately forming polytrimethylene terephthalate fibers and dissimilar fibers.

  The third problem-solving means is that at least one polytrimethylene terephthalate fiber and different types of fibers of the brush bristle material constituting the brush roll are gradually changed from a large to a small cross-sectional area as it approaches the hair end. It is formed like this.

  The fourth problem-solving means is such that a step is formed in the bristle length of the polytrimethylene terephthalate fiber and the dissimilar fiber of the brush bristle material constituting the brush roll. For example, the outer periphery of the brush roll is formed in a state in which the height difference of the brush bristle material is provided instead of the uniform height.

  In the fifth problem solving means, at least one cross section of the polytrimethylene terephthalate fiber and the different fiber of the brush bristle material constituting the brush roll is formed in a polygonal shape.

  The sixth problem solving means is that at least one or more of the polytrimethylene terephthalate fibers and the different kinds of fibers of the brush bristle material constituting the brush roll are formed in a twisted body.

  In the seventh problem solving means, at least one polytrimethylene terephthalate fiber and different types of fibers of the brush bristle material constituting the brush roll are formed with a cracked portion.

  The eighth problem-solving means is one in which at least one polytrimethylene terephthalate fiber and different fiber of the brush bristle material constituting the brush roll has a refracting part or a bent part.

  The operation of the first problem solving means is as follows. According to the configuration of the brush roll of the present invention, the brush bristle material of the brush roll is composed of polytrimethylene terephthalate fibers, or polytrimethylene terephthalate fibers and different types of fibers. As described above, in any case, the structure of the brush roll includes polytrimethylene terephthalate fiber. The polytrimethylene terephthalate fiber has a very high elongation recovery rate and an excellent bending recovery force against bending load because the molecular chain is bent in a zigzag spring shape in the fiber axis direction in the crystal structure. Therefore, the bed litter of the brush bristle material does not occur over a long period of time by using the polytrimethylene terephthalate fiber for the brush bristle material. Even when polytrimethylene terephthalate fibers and different types of fibers are mixed in the brush hair material of the brush roll, the polytrimethylene terephthalate fibers function as pillars or walls in the brush roll, and the bending recovery force of the different types of fibers. The shortage can be compensated.

  Moreover, according to this invention, the brush bristle material of a brush roll is comprised from the polytrimethylene terephthalate fiber or the polytrimethylene terephthalate fiber and a different kind | species fiber. As mentioned above, polytrimethylene terephthalate fibers are included in all cases. Polytrimethylene terephthalate fiber is a fiber having a very low water absorption compared to nylon 6 or nylon 66. Therefore, by adding the polytrimethylene terephthalate fiber to the structure, it is possible to make it difficult to receive moisture absorption, swelling due to water absorption, or reduction in stiffness of the brush bristle material under water spray or water. Further, the polytrimethylene terephthalate fiber is strong against acid and can impart excellent acid resistance to the brush roll.

  Further, the brush bristle material of the brush roll is composed of polytrimethylene terephthalate fibers, or polytrimethylene terephthalate fibers and different fibers. As mentioned above, polytrimethylene terephthalate fibers are included in all cases. Polytrimethylene terephthalate fiber has a polyester-based molecular structure, so it can be chemically recycled after use, and when it is inevitably incinerated, it is composed of elements of oxygen, carbon, and hydrogen. The emissions from complete combustion can be only water and carbon dioxide.

  In addition, the second problem solving means has an excellent bending recovery force because polytrimethylene terephthalate fibers and different kinds of fibers having an excellent bending recovery force characteristic with respect to the bending load are alternately formed in the brush roll. Polytrimethylene terephthalate fibers with properties serve as pillars or walls in brush rolls. Further, by arranging regularly, it is possible to effectively and stably compensate for the lack of bending recovery force of different types of fibers.

  In addition, the action of the third problem solving means enables effective contact of the bristle material by gradually changing the cross-sectional area of the bristles from large to small with respect to the fine uneven shape. . Usually, when the cross-sectional area of the bristle tip is made small, the bending recovery force of the bristle material is extremely inferior, and a predetermined bending elasticity cannot be obtained. However, since polytrimethylene terephthalate fiber can obtain a very high elongation recovery rate or excellent bending recovery property, it is possible to use polytrimethylene terephthalate fiber, or polytrimethylene terephthalate fiber and a different kind of fiber for the brush bristle material. It is possible to avoid falling into the bending recovery of the brush bristle material. Further, the polytrimethylene terephthalate fiber can be easily formed into a tapered shape with a strong alkali.

  Further, the action of the fourth problem solving means is that a step is formed in the bristle length of the polytrimethylene terephthalate fiber of the brush bristle material of the brush roll or the different fiber from the polytrimethylene terephthalate fiber, for example, hair When the bristle length of polytrimethylene terephthalate fiber with strong waist is lowered and the hair length of dissimilar fibers with weak bristle height is raised, the hair waist of the brush bristle against the workpiece surface is strong at the tip of the hair Can be set weakly. In addition, when the bristle length of polytrimethylene terephthalate fiber is increased and the length of heterogeneous fiber with weak bristle width is lowered, the polytrimethylene terephthalate fiber has a higher bristle length than the heterogeneous fiber. The degree of freedom of trimethylene terephthalate fiber is high, and it can be brought into contact with the surface of the workpiece with higher elasticity. Therefore, the bristles of the brush roll can be arbitrarily set by changing and setting the level of the step.

  Further, the fifth problem solving means has the effect that at least one cross section of the polytrimethylene terephthalate fiber of the brush bristle material constituting the brush roll, or the polytrimethylene terephthalate fiber and the dissimilar fiber is formed in a polygonal shape. As a result, a polygon with a longer edge length can be obtained compared to a cylindrical shape with a short outer peripheral length, and a wide range can be processed efficiently.

  Further, the sixth problem solving means has an effect that at least one polytrimethylene terephthalate fiber of the brush bristle material constituting the brush roll, or at least one polytrimethylene terephthalate fiber and a different kind of fiber is formed into a twisted body. The polytrimethylene terephthalate fiber is twisted like a spring, and the bending recovery force can be further increased.

  In addition, the seventh problem solving means has the effect that at least one polytrimethylene terephthalate fiber of the brush bristle material constituting the brush roll, or at least one polytrimethylene terephthalate fiber and a different kind of fiber forms a cracked portion. It is possible to contact the brush material effectively with respect to the fine uneven shape. Usually, when a cracked portion is formed at the tip of the bristle material, one bristle material is divided into countless fine hairs, resulting in a state where the bending recovery force is extremely insufficient. However, since polytrimethylene terephthalate fiber has excellent bending recovery characteristics, it can hardly fall into bending recovery.

  The eighth problem-solving means is characterized in that the polytrimethylene terephthalate fiber of the brush bristle material constituting the brush roll, or the polytrimethylene terephthalate fiber and the dissimilar fiber are formed in a zigzag shape to form a polytrimethylene terephthalate fiber. In addition to the state in which the methylene terephthalate fiber is in a crystal structure and the molecular chain is bent in a zigzag spring shape in the fiber axis direction, the external shape of the polytrimethylene terephthalate fiber and the dissimilar fiber is refracted or bent in a spring shape, so that the external The stress can be released smoothly at the bent and refracted portions. In addition, when the external stress disappears, the original shape is smoothly restored. Therefore, it is possible to further increase the bending recovery force by providing a refraction or bending portion.

  The brush roll of the present invention is a brush that comes into contact with a work surface in cleaning, grinding, polishing, surface treatment, cleaning, and deburring of a steel plate, a non-ferrous metal plate, a resin plate, a film-like composition, and a glass plate. Polytrimethylene terephthalate fiber boasting a very high elongation recovery rate and bending recovery force because the molecular chain is bent in a zigzag spring shape in the crystal axis direction in the brush bristle material configured in the roll By using a single fiber or a different kind of polytrimethylene terephthalate fiber, the brush roll can be given a strong bending recovery force against the bending and bending of the hair material itself due to repeated bending loads, and bedding can hardly occur. Furthermore, by using polytrimethylene terephthalate fiber in the hair material, it is possible to prevent swelling due to water absorption and to eliminate the point that the stiffness of the brush hair material is lowered, and to improve acid resistance. The initial ability of the brush roll can be maintained for a long time under a wide range of conditions such as water droplets, water, and acidic liquid. Further, the polytrimethylene terephthalate fiber can be chemically recycled after use, and a brush roll can be manufactured in consideration of environmental problems.

  In the first invention, the brush roll of the present invention is composed of at least a core material or a base and a hair material, and the hair material is composed of polytrimethylene terephthalate fiber, or polytrimethylene terephthalate fiber and a different kind of fiber. It has been done. As described above, in any case, the structure of the brush roll includes polytrimethylene terephthalate fiber. Polytrimethylene terephthalate fiber has a very high elongation recovery rate and an excellent bending recovery force against bending load because the molecular chain is bent in a zigzag spring shape in the fiber axis direction in the crystal structure. Therefore, the bed litter of the brush bristle material does not occur over a long period of time by using the polytrimethylene terephthalate fiber for the brush bristle material.

  Further, as described above, the brush bristle material of the brush roll of the present invention is composed of polytrimethylene terephthalate fibers, or polytrimethylene terephthalate fibers and different types of fibers. In either case, polytrimethylene terephthalate fibers are included. Polytrimethylene terephthalate fiber is a fiber having a very low water absorption compared to nylon 6 or nylon 66. Therefore, by adding polytrimethylene terephthalate fiber to the structure, it is possible to make it difficult to receive moisture absorption, swelling due to water absorption, or reduction in stiffness of the brush bristle material under water spray or water. Further, the polytrimethylene terephthalate fiber is strong against acid and can impart excellent acid resistance to the brush roll.

  Further, as described above, the brush bristle material of the brush roll of the present invention is composed of polytrimethylene terephthalate fibers, or polytrimethylene terephthalate fibers and different types of fibers. In either case, polytrimethylene terephthalate fibers are included. Since polytrimethylene terephthalate fiber is composed of elements of oxygen, carbon, and hydrogen, it can be chemically recycled after use.

  Currently, chemical recycling that the Containers and Packaging Recycling Law recognizes as a recycling method for re-commercialization includes raw material / monomerization, oil conversion, use as a blast furnace reducing agent, coke oven chemical raw material, and conversion to chemical raw materials by gasification. is there. With polytrimethylene terephthalate fiber, chemical recycling that can be recycled by applying heat and pressure to the original petroleum or basic chemical raw material is possible by utilizing the fact that the raw material is made of carbon and hydrogen.

  Moreover, even if it is unavoidable to incinerate, the emissions from complete combustion can be only water and carbon dioxide.

  In the second invention, polytrimethylene terephthalate fibers and different kinds of fibers having an excellent bending resilience characteristic with respect to a bending load are alternately formed in a brush roll. As described above, since the polytrimethylene terephthalate fiber bristle has excellent bending recovery characteristics, the polytrimethylene terephthalate fiber bristle structurally functions as a column or wall in the brush roll. For example, nylon, PET, PP, PE and other fiber hair materials are inferior in bending recovery compared to polytrimethylene terephthalate fiber hair materials. Nylon, PET, PP, PE and other fiber hair materials fall short of bending recovery power In addition, the polytrimethylene terephthalate fiber bristle material having sufficient bending recovery force pushes the state where the fiber bristle material such as nylon, PET, PP, PE, etc. falls and leans against it, making it difficult for bedclothes to occur in the brush roll. Further, by arranging regularly, it is possible to more stably and effectively compensate for the insufficient bending recovery force of different kinds of fibers.

  According to a third aspect of the present invention, at least one of the brush bristle materials of the brush roll of the present invention is formed so that the cross-sectional area gradually changes from large to small as it gets closer to the hair tip. On the other hand, by reducing the cross-sectional area of the front end portion of the bristle material, it is possible to contact the brush bristle material effectively so that the hair tips reach even a slight gap between the irregularities. Usually, when the cross-sectional area of the bristle material decreases, the bending recovery force of the bristle material is remarkably inferior, and a predetermined bending elasticity cannot be obtained. However, since polytrimethylene terephthalate fiber can obtain a very high elongation recovery rate or excellent bending recovery property, it is possible to use polytrimethylene terephthalate fiber, or polytrimethylene terephthalate fiber and a different kind of fiber for the brush bristle material. Even if the cross-sectional area of the bristle material is reduced, it is difficult for the brush bristle material to fall short of the bending recovery force. Further, the polytrimethylene terephthalate fiber can be easily formed into a shape having a narrow tip by impregnating with strong alkali.

  4th invention forms the level | step difference in the bristle length of the polytrimethylene terephthalate fiber of the said brush bristle material of a brush roll, or a polytrimethylene terephthalate fiber and a different kind | species fiber. For example, if the work surface is very fragile and deep, the brush bristle material is brought into deep contact with the work surface so that the brush bristle material reaches the lower part of the work surface. To do. However, in this case, there is a high possibility that a high pressure is applied to the processed surface to damage the high portion of the processed surface, and that the fluff is too soft in the low portion. In the above problem, the following solutions can be considered. By reducing the bristle length of polytrimethylene terephthalate fibers having strong bristle and increasing the bristle length of different fibers having weak bristle, the brush is applied to the work surface. The bristle material can be set so that the bristle portion is strong and the bristle tip portion is weak, making it difficult to damage the work surface, and can be brought into contact with the whole regardless of whether the work surface is high or low. Also, when the hair length of polytrimethylene terephthalate fibers with strong fur is increased and the length of dissimilar fibers with weak fur is lowered, polytrimethylene terephthalate fibers with high hair length protrude from the different fibers. The methylene terephthalate fiber has a high degree of freedom and can be brought into contact with the surface of the workpiece with higher elasticity. As described above, it is possible to arbitrarily change and set the bristles of the brush roll by changing and setting the degree of step difference between the length of the polytrimethylene terephthalate fiber and the length of the different fiber.

  According to a fifth aspect of the present invention, at least one of the polytrimethylene terephthalate fibers of the brush bristle material constituting the brush roll, or the polytrimethylene terephthalate fibers and the different types of fibers is formed in a polygonal shape, so that only the outer peripheral length is formed. In comparison with the cylindrical shape, a long edge length can be obtained with a polygon, and an edge is formed in the fiber axis direction of the hair material. Furthermore, it is possible to set sharp edges with three lines intersecting each angle, and it is possible to efficiently process a wide range of the work surface with the edges of the brush bristle material.

  According to a sixth aspect of the present invention, at least one polytrimethylene terephthalate fiber of the brush bristle material constituting the brush roll, or at least one polytrimethylene terephthalate fiber and a different kind of fiber is formed into a twisted body, so that the outer shape is a spring shape. As with a spring, it releases stress smoothly against external stress. Also, since the stress recovers smoothly when the stress disappears, the bending recovery force can be further increased. Also, when different fibers are made of nylon, PET, PP, PE, etc., the fibers of nylon, PET, PP, PE, etc. are inferior in bending recovery compared to polytrimethylene terephthalate fibers. By twisting a polytrimethylene terephthalate fiber having excellent bending recovery characteristics into a twisted body, the polytrimethylene terephthalate fiber serves as a core material for the hair material. Therefore, it effectively compensates for insufficient bending recovery force of fibers such as nylon, PET, PP, PE, etc., and it becomes difficult for the brush roll bristle material to be littered.

  In the seventh invention, at least one polytrimethylene terephthalate fiber of the brush bristle material constituting the brush roll, or at least one polytrimethylene terephthalate fiber and a different kind of fiber forms a cracked portion, whereby a plurality of bristle tips are formed. By dividing into a book and reducing the cross-sectional area per one, an effective brush bristle material can be contacted so that the hair ends reach even a slight gap between the irregularities. Usually, forming a crack at the tip of a bristle means dividing one bristle into countless fine hairs. The cross-sectional area per divided fine hair is reduced as compared with the original bristle material. When the cross-sectional area of the bristle material is reduced, the bending recovery force of the bristle material is remarkably inferior, and a predetermined bending elasticity cannot be obtained. However, since polytrimethylene terephthalate fiber can obtain a very high elongation recovery rate or excellent bending recovery property, it is possible to use polytrimethylene terephthalate fiber, or polytrimethylene terephthalate fiber and a different kind of fiber for the brush bristle material. Even if the cross-sectional area of the bristle material decreases, it becomes difficult for the bristle material of the brush bristle material to fall short.

  In the eighth invention, the polytrimethylene terephthalate fiber has a crystal structure and the molecular chain is bent in a zigzag spring shape in the fiber axis direction. By bending and bending the outer shape of the polytrimethylene terephthalate fiber of the brush bristle material, or polytrimethylene terephthalate fiber and a different type of fiber, the bending and bending part can be smoothly bent against the external stress like a spring. Stress can be released. In addition, since the stress recovers smoothly when the stress disappears, it is possible to further increase the bending recovery force by providing a bent or refracted portion.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, this invention is not limited by this embodiment.

  Example 1 is shown in FIG. 1, FIG. 2, FIG. 5 and FIG. FIG. 1 is a perspective view of a brush roll used for cleaning, grinding, polishing, surface treatment, and cleaning using the brush bristle material of the present invention as seen from the front. In FIG. 1, 1 is a brush roll, 2 is a core wire, 3 is a polytrimethylene terephthalate fiber brush hair, 4 is a dissimilar fiber brush hair, 5 is a brush surface, 6 is a core material and 2 core wires are twisted. . FIG. 2 is a perspective view of another embodiment of the first embodiment as viewed from the front. In FIG. 2, 10 is a brush roll, 11 is a dissimilar fiber brush hair, 12 is a polytrimethylene terephthalate fiber brush hair, 13 is a channel brush, 14 is a stopper, 15 is a core material, and 16 is a brush surface. FIG. 5A is an enlarged perspective view of a cross section of the channel brush 13 in FIG. 50 is a belt-like body, 51 is a polytrimethylene terephthalate fiber brush hair, 52 is a dissimilar fiber brush hair, and 53 is a core wire. FIG. 5B is an enlarged perspective view of the fastener 14 of FIG. 55 is an alligator and 56 is a fixing bolt. FIG. 6A is a perspective view of another embodiment of the first embodiment as viewed from the front. In FIG. 6A, 60 is a brush roll, 61 is a flocking hole, 62 is a base, and 63 is a polytrimethylene terephthalate fiber brush hair or a different fiber brush hair. FIG. 6B is a partially enlarged view of FIG. In FIG. 6B, 61 is a flock hole, 65 is a different fiber brush hair, 66 is a polytrimethylene terephthalate fiber brush hair, and 67 is a flat wire.

  As shown in FIG. 1, the brush roll 1 of the present invention includes a core material 6, polytrimethylene terephthalate fiber brush bristles 3, and different fiber brush bristles 4. The brush roll 1 includes the polytrimethylene terephthalate fiber brush bristles 3 alone, or the polytrimethylene terephthalate fiber brush bristles 3 and the dissimilar fiber brush bristles 4 sandwiched between the plurality of core wires 2 and then twists the core wires 2 to form the polytrimethylene terephthalate fiber bristles 3. Only the methylene terephthalate fiber brush bristles 3 or the polytrimethylene terephthalate fiber brush bristles 3 and the dissimilar fiber brush bristles 4 are caulked and locked with a core wire.

  Next, the operation of the brush roll 1 will be described. The brush roll 1 is used by attaching a core material 6 in which a plurality of core wires 2 are twisted to a rotating device such as a drill or a milling machine, various jigs, etc., and bringing the brush surface 5 into contact with the work surface. In contact, frictional resistance is generated between the brush surface 5 and the surface to be processed. The dust on the surface to be processed is peeled off from the surface to be processed by the frictional resistance, and the dust is blown off by the bending recovery force of the bristle material to perform cleaning and surface treatment. Moreover, it can also be used for grinding, polishing, and deburring by including an abrasive material in the bristle material. Furthermore, if the brush roll 1 or the processing surface is in liquid, the processing surface can be cleaned.

  As described above, in the brush roll 1, the brush surface 5 comes into contact with the surface to be processed, and the brush bristle material receives bending stress at the contact portion. Further, when the brush roll 1 is inserted into the cylindrical inner surface and then rotated with the brush roll 1 in contact with the cylindrical inner surface, for example, the brush roll 1 is always subjected to bending stress over the entire circumference. When a bending load is always applied to the brush bristle material, the bristle material will be plastically deformed and become a bedding state. By including the polytrimethylene terephthalate fiber brush bristle 3 having an excellent bending recovery force, It is possible to provide a brush roll that maintains the contact of the same condition on the work surface over a long period of time.

  Next, another embodiment of Example 1 in FIG. 2 will be described. 2 of FIG. 2 is the perspective view which looked at the brush roll of other embodiment from the front. The brush roll 10 is formed of a core material 15, a channel brush 13, a fastener 14, a polytrimethylene terephthalate fiber brush bristles 12 alone, or a polytrimethylene terephthalate fiber brush bristles 12 and a dissimilar fiber brush bristles 11. The core material 15 has a substantially cylindrical shape, and is formed by attaching fasteners 14 to both ends of the outer periphery.

  FIG. 5 is an enlarged view of the channel brush 13 and the fastener 14 of FIG. The channel brush 13 has a polytrimethylene terephthalate fiber bristle 51 or a dissimilar fiber bristle 52 between the existing C-shaped groove and the retaining core wire 53 as shown in FIG. As shown in FIG. 2, after being sandwiched and folded by the core wire 53, the polytrimethylene terephthalate fiber bristles 51 and the dissimilar fiber bristles 52 are alternately arranged by twisting around the outer periphery of the core material 15 as shown in FIG. After forming the spiral shape and locking the alligator 55 to the core member 15 with the fixing bolt 56, the band-shaped body 50 is locked to the alligator 55.

  Next, the operation of the brush roll 10 of the present invention will be described. The brush roll 10 is rotated while the core material 15 is mounted on a rotating device and the brush surface 16 is pressed against and contacted with the surface to be processed. As the bristle material of the brush roll and the work surface rub against each other, a frictional resistance is generated between them. The dust on the surface to be processed is peeled off from the surface to be processed due to the frictional resistance, and the dust is blown off by the bending recovery force of the bristle material to perform cleaning and surface treatment. Moreover, it can also be used for grinding, polishing, and deburring by including an abrasive material in the bristle material. Furthermore, if the brush roll 10 or the processing surface is in liquid, the processing surface can be cleaned.

  As described above, since the brush roll 10 rubs against the work surface while being pressed against the brush roll 10, the polytrimethylene terephthalate fiber bristles 12 and the dissimilar fiber bristles 11 are subjected to bending stress at the contact portions. Further, since the brush roll 10 is rotating, the polytrimethylene terephthalate fiber brush bristles 12 and the dissimilar fiber brush bristles 11 are subjected to bending stress at the portion in contact with the workpiece, and the polytrimethylene terephthalate fiber bristles 12 The dissimilar fiber brush bristles 11 are released from the bending stress at the portions that do not come into contact with the workpiece. Since this process is repeated over the entire circumference, the bending load is constantly applied to the polytrimethylene terephthalate fiber brush bristles 12 and the different fiber brush bristles 11. Furthermore, by repeating the above operation, the polytrimethylene terephthalate fiber brush bristles 12 and the dissimilar fiber brush bristles 11 cause plastic deformation and lead to sleeping, however, the polytrimethylene terephthalate fiber brush bristles 12 having excellent bending recovery force are brushed. By including in the configuration of the roll 10, in the configuration of the brush roll 10, the polytrimethylene terephthalate fiber brush bristles 12 having excellent bending recovery force serve as pillars or walls in the brush structure. Compared with the polytrimethylene terephthalate fiber brush bristles 12, the polytrimethylene terephthalate having an excellent bending recovery force can be obtained when the dissimilar fiber brush bristles 11 inferior in bending recovery force cannot be recovered due to bending stress and fall down. The fiber brush bristles 12 push back the dissimilar fiber bristles 11. Further, in the case of the brush roll 10, the polytrimethylene terephthalate fiber brush bristles 12 and the heterogeneous fiber brush bristles 11 are formed in a spiral shape so that the polytrimethylene terephthalate fiber brush bristles 12 are irregularly placed in the brush roll. Compared to the arranged brush rolls, it is possible to provide a brush roll that more effectively suppresses the generation of bedclothes and maintains the contact of the same condition on the work surface for a long time.

  Next, another embodiment of Example 1 in FIG. 6 will be described. The brush roll 60 shown in FIG. 6A has a flock hole 61 slightly drilled in the base 62 in advance in the longitudinal direction of the flat line 67 shown in FIG. After trimming the trimethylene terephthalate fiber brush bristles 66 and the dissimilar fiber brush bristles 65 and sandwiching the flat wire 67, the polytrimethylene terephthalate fiber bristles 66, the dissimilar fiber brush bristles 65 and the flat wire are perpendicular to the flock holes 61. 67 is inserted and caulked and locked. In general, the above-described flocking method using a flat wire 67 having a square plate shape is referred to as flat flocking. In addition to the flat wire 67, a flocking method in which an already circular shape is used and inserted and locked is generally referred to as round wire flocking.

  When the polytrimethylene terephthalate fiber brush hair and the different fiber brush hair are used in combination with the brush bristle material constituting the brush roll, the polytrimethylene terephthalate fiber brush hair and the different fiber brush hair may be mixed in advance and implanted.

  As shown in FIG. 6 (B), a method in which the hair material of the brush roll is pre-mixed with different types of brush hairs such as polytrimethylene terephthalate fiber 66 and dissimilar fiber 65, and is then generally referred to as mixed hair. .

  Example 2 is shown in FIG. 3A and FIG. FIG. 3A is an enlarged perspective view of polytrimethylene terephthalate fiber brush bristles and dissimilar fiber brush bristles whose ends are processed into a hemispherical shape. 20 is a polytrimethylene terephthalate fiber brush bristles and heterogeneous fiber brush bristles, and 21 is a hemispherical hair tip. FIG. 3B is an enlarged perspective view of polytrimethylene terephthalate fiber brush bristles and dissimilar fiber brush bristles with tapered ends. Reference numeral 23 denotes a tapered tip shape.

  In FIG. 3, at least one of the polytrimethylene terephthalate fiber brush bristle material and the heterogeneous fiber brush bristle material is formed so that the cross-sectional area gradually changes from large to small as it approaches the hair tip. In FIG. 3, the tip shape is a pre-hemispherical shape 21. A flat surface portion may be formed at the tip portion. In the portion 22 in FIG. 3, a tip tapered shape 23 portion is formed. A flat surface portion may be formed at the tip portion.

  Next, the operation of the brush roll of Example 2 using the polytrimethylene terephthalate fiber bristles 20 and 22 of FIG. When the surface to be processed is fine unevenness, the brush hair processed so that the cross-sectional area of the hair tip becomes larger or smaller like the semispherical shape 21 or the sharply tapered portion 23 than the unevenness of the processing surface. By using the material, the tip can enter the fine irregularities, so that the fine irregularities can be cleaned, surface-treated, washed, and the like. In addition, since the edge perpendicular to the tip is not formed, it is possible to prevent and suppress the occurrence of scratches, dents and the like on the surface to be processed.

  Further, Example 3 is shown in FIG. FIG. 3C is a top front view of polytrimethylene terephthalate fiber brush bristles and dissimilar fiber brush bristles with a step difference in bristle length. 24 is a polytrimethylene terephthalate fiber brush bristles and different fiber brush bristles, 25 is a polytrimethylene terephthalate fiber brush bristles and different fiber brush bristles with high bristles, 26 is a polytrimethylene terephthalate fiber brush bristles with low bristles and It is a heterogeneous fiber brush hair. 27 represents the height difference between 25 and 26.

  Next, Embodiment 3 will be described with reference to 24 in FIG. 3 in FIG. 3 is a brush roll formed by planting hair materials of brush hairs 25 having high bristles and brush hairs 26 having low bristles in the brush roll of the third embodiment. When the brush roll is already cylindrical, since the hair length is not uniform, the outer peripheral portion is uneven.

  Next, the operation of the brush roll of FIG. 3 of the present invention will be described in comparison with a brush roll not using the present invention. For example, if the work surface is very fragile and wrinkled, polytrimethylene terephthalate fiber brush bristles or dissimilar fiber brush bristles are brought into deep contact with the work surface to a lower part of the work surface. It must be set at a position where the polytrimethylene terephthalate fiber bristles or different types of fiber bristles can reach. For example, if the bristle length is the same height and the brush bristle material is the same, high pressure is likely to be applied to the work surface due to high pressure on the work surface, but the work surface The lower back of the hair may be too soft or unreachable. However, the above problem can be avoided or alleviated by forming a step in the bristle length of the polytrimethylene terephthalate fiber brush bristles or different fiber brush bristles of this brush bristle material. The following solution can be considered by using the 24 bristles of FIG. 3 of the present invention, and the length of the bristle-rich polytrimethylene terephthalate fiber brush bristles is as low as 26, and the bristle is weak. By setting the length of the fiber brush bristles as high as 25, the base of the hair is closely planted with the polytrimethylene terephthalate fiber bristles 26 and the dissimilar fiber bristles 25 on the workpiece surface. The bristle is strong, and the hair tip part of the dissimilar fiber bristle material 25 is weak in bending recovery and is planted in a sparse state. Can be made difficult to attach to the surface to be processed. In addition, when the bristle length of the polytrimethylene terephthalate fiber brush with strong bristle is increased as shown in 25 and the bristle length of the weak fiber with low bristle as shown in 26, the polytrimethylene is reduced with respect to the heterogeneous fiber. Where the terephthalate fiber bristles are high in length and the polytrimethylene terephthalate fiber brush bristles 25 protrude, the polytrimethylene terephthalate fiber bristles 25 have a high degree of freedom and should be brought into contact with the workpiece surface with higher elasticity. Can do. As described above, it is possible to arbitrarily change and set the bristles of the brush roll by changing and setting the level difference between the lengths of the polytrimethylene terephthalate fiber bristles and the different fiber bristles.

  Next, FIG. 4 will be described. 4A, 4C, and 4D show another embodiment of the second embodiment. 4A, 4C, and 4D are partially enlarged views of polytrimethylene terephthalate fiber brush bristles and dissimilar fiber brush bristles. FIG. 4B is a partially enlarged view of FIG. 2 of another embodiment of the first embodiment. 4 in FIG. 4 is an enlarged perspective view of a cut surface of polytrimethylene terephthalate fiber or different fiber formed in a polygonal shape as viewed from above. 31 is a ridgeline. Reference numeral 35 in FIG. 4 is a partially enlarged view of the brush hair in which a bent portion or a refracting portion is provided on a polytrimethylene terephthalate fiber or a different kind of fiber as viewed from the front upper part. Reference numeral 37 denotes a bent or refracted portion. 4 in FIG. 4 is a partially enlarged view of a brush hair obtained by subjecting a polytrimethylene terephthalate fiber or a dissimilar fiber to a pre-cracking process as viewed from the front.

  Another embodiment of the second embodiment will be described with reference to FIG. 4 in FIG. 4 shows the tip of the roll brush 1 of Example 1 or the roll brush 10 of another embodiment of Example 1 or the polytrimethylene terephthalate fiber brush bristles used in 60, or the tips of different types of fiber brush bristles. It is an enlarged view. In FIG. 4, the cross-sectional shape of the bristle 30 is an existing triangular shape, and sixteen ridge lines are formed along the triangular shape.

  The operation of 30 polytrimethylene terephthalate fiber brush bristles or different fiber brush bristles in FIG. 4 will be described. Grinding, polishing, surface treatment, cleaning, and deburring are generally performed by scraping or removing the work surface. In this case, if the brush roll bristle material has as many edges as possible and is formed at an acute angle, the resistance to the surface to be processed increases, the amount of scraping or stripping can be increased, and the processing time can be shortened. . In order to make the edges large and sharp, at least one cross-section of polytrimethylene terephthalate fiber hairs of 30 brush bristle materials or polytrimethylene terephthalate fiber hairs and different fiber hairs should be formed in a polygon. Thus, when compared with a cylindrical shape and a cross-sectional area, a long edge length can be obtained with a polygon compared to a cylindrical shape with only an outer peripheral length. Further, in the hair material having the shape 30 in FIG. 4, an edge is further formed in the fiber axis direction, and six ridge lines are formed as 31. In addition, it is possible to set sharp edges with three angles intersecting each other, and a wide range of the work surface can be processed in a short time.

  The cross-sectional shape of the polytrimethylene terephthalate fiber brush bristles 30 or the dissimilar fiber brush bristles in FIG. 4 is not limited to the above triangle shape, and may be a polygonal shape having polygons.

  Next, another embodiment of the second embodiment will be described with reference to FIG. 35 is a polytrimethylene terephthalate fiber brush bristles or different fiber brush bristles, 37 is a bent, refracted part,

  Reference numeral 35 in FIG. 4 denotes polytrimethylene terephthalate fiber brush bristles or heterogeneous fiber brush bristles in which a refracting or bent portion 37 is formed. When the refracting or bending portion 37 is provided, external stress can be smoothly released like a spring at the bending and refracting portion when external stress is applied to the polytrimethylene terephthalate fiber brush bristles and different fiber brush bristles. Further, when the external stress is not received, the shape restoration is performed smoothly.

  Next, the operation 35 in FIG. 4 will be described. Since the brush rolls rub against each other while being pressed against the surface to be processed, the brush hair 35 receives bending stress from the contact portion. Further, since the brush roll is rotating, the bending stress is received at the portion where the brush bristles 35 and the workpiece are in contact, and the bending stress is released at the portion where the brush bristles 35 and the workpiece are not in contact. Is repeated over the entire circumference, the bending load is always applied to the brush bristle material 35 repeatedly. However, the brush roll of 35 in FIG. 4 uses polytrimethylene terephthalate fiber brush hair having an excellent bending recovery force, and as described above, the bent and refracted portion 37 is made of polytrimethylene terephthalate fiber brush hair. Alternatively, when external stress is applied by disposing different kinds of fiber brush bristles, the external stress is smoothly released like a spring at the bent / refracted portion 37, and when the external stress disappears, the shape is restored smoothly and excellent bending recovery is achieved. You can get power.

  Next, another embodiment of the second embodiment will be described with reference to FIG. (D) of FIG. 4 is a pointed hair material of polytrimethylene terephthalate fiber or different fiber. No. 38 is obtained by processing polytrimethylene terephthalate fiber brush bristles or dissimilar fiber brush bristles into a shape obtained by dividing in the fiber axis direction. Reference numeral 39 denotes a divided portion, and 40 denotes a divided unprocessed portion, which has the same shape as the original shape of the brush hair.

  The shape of the polytrimethylene terephthalate fiber 38 or the different fiber 38 in FIG. 4 is cut in the direction of the fiber axis by using a rotary cutter or the like at the tip of the existing cylindrical or polygonal brush bristles, and a plurality of brush bristles. Divided into two. The processing method is generally called pre-cracking. Further, 39 that has been subjected to the cracking process is called a cracked part.

  Next, the operation 38 in FIG. 4 will be described. At least one of the polytrimethylene terephthalate fiber of the brush bristle material constituting the brush roll, or at least one of the polytrimethylene terephthalate fiber and the dissimilar fiber is formed as described above. By carrying out the tip cracking process, the cross-sectional area of each bristle material 39 divided by the tip crack is smaller than the original cross-sectional area of the brush bristle material 40. If the diameter of the bristle material 39 divided from the minute gaps of the fine uneven shape is small, it becomes possible to bring the hair tips into contact with the slight uneven shape gaps, Effective cleaning, grinding, polishing, surface treatment, cleaning, and deburring are possible. However, generally, when the cross-sectional area of the bristle material decreases, the bristle's bending recovery force is remarkably inferior, and a predetermined flexural elasticity cannot be obtained. Since the polytrimethylene terephthalate fiber of the present invention can obtain a very high elongation recovery rate or an excellent bending recovery force characteristic, by using the polytrimethylene terephthalate fiber in 38 of the brush bristle material in FIG. Even if the cross-sectional area of the bristle material is reduced, it becomes difficult for the bristle material of the brush bristle material to fall short.

  Next, Embodiment 4 will be described with reference to FIG. FIG. 4B is an enlarged view of the front upper part of a twisted body of polytrimethylene terephthalate fiber brush bristles and dissimilar fiber brush bristles. 32 is a brush hair formed by twisting a polytrimethylene terephthalate fiber brush hair and a different fiber brush hair into a single strand, and 34 is a polytrimethylene terephthalate fiber brush hair. 33 is a dissimilar fiber brush hair.

  4 is formed in a state in which a plurality of different fiber brush bristles 33 or polytrimethylene terephthalate fiber brush bristles are twisted and twisted in a spiral shape, and the twisted material like 32 in FIG. 4 is generally used. In particular, it is called twisted yarn.

  The operation 32 in FIG. 4 will be described. Polytrimethylene terephthalate fiber brush bristles 34 with different types of fiber brush bristles 33 have a helically twisted shape, which is the same shape as a coil spring having a high recovery force against bending stress, Compared with the brush hair, the brush hair twisted in a spiral shape has excellent bending recovery power. Furthermore, by twisting several pieces, the pressure resistance applied in the direction of the brush bristle axis increases, so the brush bristle material 32 in FIG. 4 is strong against bending pressure and falling down, and is difficult to sleep. Further, when the different fiber brush bristles 33 are made of fibers such as nylon, PET, PP, PE, etc., the different fiber brush bristles 33 such as nylon, PET, PP, PE, etc. are inferior in bending recovery force compared to the polytrimethylene terephthalate fiber bristles 34. However, since the polytrimethylene terephthalate fiber bristles 34 are present in the hair material of the brush roll twisted body, the polytrimethylene terephthalate fiber bristles 34 having excellent bending recovery characteristics serve as a core material, so that nylon It effectively compensates for the insufficient bending recovery force of the fiber bristles 33 such as PET, PP, PE, etc., and the roll brush bristles are less likely to be littered.

  The combination of the brush bristle material constituting the brush roll of the present invention is a combination using only polytrimethylene terephthalate fiber brush bristles, or a combination of polytrimethylene terephthalate fiber brush bristles and dissimilar fiber bristles. The methylene terephthalate fiber brush bristles are not limited to one type of different fiber brush bristles, and may be used in combination of several types.

  The heterogeneous fibers refer to those other than polytrimethylene terephthalate fibers such as nylon, PET, PP, PE, urethane, and acrylic.

  The method for flocking the brush roll is not particularly limited, and other than the flocking method as described above, it can be set as appropriate according to the purpose of use.

  The brush roll of the present invention is mainly used for cleaning, grinding, polishing, surface treatment, washing, and deburring of steel plates, non-ferrous metal plates, resin plates, film-like compositions, glass plates and the like. Moreover, it can be used widely and suitably, such as cleaning brushes for the inner and outer surfaces of various vehicles such as automobiles, trains, buses, indoor cleaning brushes in general households or offices, and rotating brushes mounted on floor nozzles of vacuum cleaners.
