Description

  The present invention relates to the removal, squeezing, and cleaning of moisture, oil, or chemical components adhering to the surface to be cleaned made of a steel plate, non-ferrous metal plate, resin plate, or film, and moisture, oil, or chemicals on the surface to be cleaned It relates to a roll for applying the components.

  Removal, extraction, cleaning of moisture, oil or chemical components adhering to the surface to be cleaned made of steel plate, non-ferrous metal plate, resin plate, or film, and application of moisture, oil or chemical components to the surface to be cleaned Various improvements have been made with respect to the roll for the purpose, for example, a method for producing a laminated roll using a highly repellent, non-viscous nonwoven fabric sheet, a cylindrical shaft body as a composite structure laminated roll, and the shaft body. And a plurality of pores formed in the cylindrical portion of the shaft main body, and the pores formed in the axial direction thereof. A highly repellent, non-viscous non-woven sheet-like material formed with a large number of discs, and a non-returning sheet-like material such as an adhesive rubber sheet, between the hollow portion communicating with the shaft main body And superimposed in close contact A roll main body formed by a roll first constituent part, a roll second constituent part interposed in a disk overlapping part of the roll first constituent part, and fitted into the shaft main body, and the bearing Japanese Laid-Open Patent Publication No. 5-180216 discloses a composite structure laminating roll that is formed in a part and is configured by a through hole that communicates with the hollow part.

  Further, as a nonwoven fabric roll, an annular grip plate made of a flexible material is inserted into an interference fit of an iron core, the grip plate and the nonwoven fabric disk are laminated, and this laminate is pressed in the direction of the iron core. JP-A-10-61657 discloses a nonwoven fabric roll characterized in that the inner peripheral end of the grip plate is pressed against the outer periphery of the iron core.

  Although the conventional roll has been disclosed as described above, a method for producing a laminated roll using a highly repellent and non-viscous nonwoven sheet material disclosed in JP-A-5-180216 and a composite structure are disclosed. In laminated rolls, a roll and a liquid removal device such as a suction pump are integrated to remove the liquid on the surface to be cleaned, so that the liquid on the surface to be cleaned can be removed by itself without using a liquid removal device such as a suction pump. Has a problem that it cannot be uniformly drained. Further, since the roll and the liquid removal device such as a suction pump are integrated, there is a problem that the equipment investment is high. Furthermore, the rubber sheet-like material inserted between the non-woven sheet-like material is uniformly inserted, and since the rotating outer diameter is the same, the deformation form of the roll part is limited and diversified to be cleaned. There was also a problem that the shape of the surface could not be accommodated.

  Further, in the nonwoven fabric roll disclosed in Japanese Patent Laid-Open No. 10-61657, there is no key on the iron core and no key groove is provided on the nonwoven fabric disk, so that a high pressure is applied to the roll. The non-woven disk is displaced from the iron core, the surface of the roll part is likely to be uneven, and it is difficult to stabilize the roll form over a long period of time, and the liquid on the surface to be cleaned is removed uniformly. I had the problem that I couldn't. In addition, since a flexible material is used for the grip plate, it is impossible to use a non-woven disk for the grip plate, and it is necessary to manufacture a grip plate made of a different material from the non-woven disk. There was also a problem of high costs.

  Japanese Patent Laid-Open No. 5-180216   Japanese Patent Laid-Open No. 10-61657

  The present invention has been made to solve the above-described problems, and can stabilize the form of the roll over a long period of time, and can cope with the diversified shape of the surface to be cleaned. An object of the present invention is to provide a roll that can uniformly remove, squeeze, wash, and uniformly apply the liquid to the surface to be cleaned.

  In order to achieve the above object, according to the present invention, the roll part constituting the roll includes a roll piece A formed in a substantially disk shape and a roll piece B having a rotation outer diameter different from that of the roll piece A. , A plurality of the roll pieces A and the roll pieces B are laminated and laminated.

  Further, the second problem solving means is such that the ratio of the number of stacked sheets of the roll piece B constituting the roll part to the roll piece A changes from large to small as the distance from the end of the roll part approaches the central part. It is a configuration.

  Further, the third problem solving means is configured such that the rotation outer diameter of the roll piece B constituting the roll portion changes from large to small as it approaches the center portion from the end portion of the roll portion. .

  The operation of the first problem solving means is as follows. That is, the roll part which comprises a roll consists of the roll piece A currently formed in the substantially disc shape, and the roll piece B from which the rotation outer diameter differs from the said roll piece A, The said roll piece A and the said roll piece B are Since the core portion of the roll portion is laminated in a plurality of layers, the roll piece A and the roll piece B are densely laminated as compared with the surface portion of the roll portion where only the roll piece A is laminated. Even when the core portion has a strong tightening force and is formed with high hardness, the surface portion can be formed with lower hardness than the core portion. For this reason, the roll piece A and the roll piece B are not displaced during the rotation of the roll, and the surface of the roll part is not uneven. Moreover, since the surface part of the roll part is superior in flexibility compared to the core part of the roll part, the roll may be flipped up by the surface to be cleaned when the surface to be cleaned comes into contact with the roll part. No.

  Further, the action of the second problem-solving means is such that the ratio of the number of stacked sheets of the roll piece B constituting the roll part to the roll piece A becomes larger and smaller as the distance from the end of the roll part approaches the central part. In order to change, the roll piece B is closely laminated | stacked with respect to the roll piece A compared with the center part at the edge part of a roll part. In steel plate washing machines, air pressure or hydraulic pressure is applied to the end of the roll part, and the strongest pressure is applied to the end of the roll part. The shape deformation is the most remarkable. In the present invention, as described above, the roll piece A and the roll piece B are misaligned at the end of the roll part because the roll piece B is densely laminated with respect to the roll piece A as compared with the center part. It does not occur and the surface part of the end of the roll part does not become uneven. Further, the center portion of the roll portion is superior in flexibility to the end portion, and when the surface to be cleaned comes into contact with the roll portion, the liquid on the surface of the surface to be cleaned is removed from the center of the surface to be cleaned. It can be easily swept away from the part to both ends.

  Also, the third problem solving means has the effect that the roll outer diameter of the roll piece B constituting the roll part changes from large to small as it approaches the center part from the end of the roll part. When pressure is applied, the central part of the roll part is easier to deform in the direction perpendicular to the longitudinal direction of the rotation shaft constituting the roll, and the shape of the surface to be cleaned is easier than the end part. It can correspond to. Moreover, since the porosity of the center part of a roll part is high compared with an edge part, more liquid can be stored in the inside of a roll part.

  As described above, the roll of the present invention can stabilize the shape of the roll over a long period of time, and can uniformly apply the liquid adhering to the surface to be cleaned in accordance with the diversified shape of the surface to be cleaned. In addition, the liquid can be uniformly applied to the surface to be removed, exploited, washed, and cleaned.

  1st invention, The roll part which comprises a roll consists of the roll piece A currently formed in the substantially disc shape, and the roll piece B from which the rotation outer diameter differs from the said roll piece A, The said roll piece A, and the said A plurality of roll pieces B are overlapped and stacked. Therefore, the roll part A and the roll part B are laminated more densely than the surface part of the roll part where only the roll piece A is laminated, and the core part is strongly tightened. Even if it has a force and is formed with high hardness, the surface portion can be formed with lower hardness than the core portion. For this reason, the roll piece A and the roll piece B are not displaced during the rotation of the roll, and the surface of the roll part is not uneven. Moreover, since the surface part of a roll part is excellent in the softness | flexibility compared with the core part of a roll part, when a steel plate contacts a roll part, a roll is not flipped up by a steel plate. In particular, when a steel plate that is generally called a thick plate having a thickness of 1 mm or more is brought into contact with the roll portion, the roll is not splashed up, and the oil content on the steel plate surface is evenly extracted from the tip portion of the steel plate. be able to.

  In the second invention, the ratio of the number of stacked sheets of the roll piece B constituting the roll part to the roll piece A changes from large to small as it approaches the center from the end of the roll part. Therefore, at the end of the roll part, the roll piece B is densely laminated with respect to the roll piece A as compared with the center part. In steel plate washing machines, air pressure or hydraulic pressure is applied to the end of the roll part, and the strongest pressure is applied to the end of the roll part. The shape deformation is the most remarkable. In the present invention, as described above, the roll piece A and the roll piece B are misaligned at the end of the roll part because the roll piece B is densely laminated with respect to the roll piece A as compared with the center part. It does not occur and the surface part of the end of the roll part does not become uneven. Moreover, the center part of the said roll part is excellent in the softness | flexibility compared with the edge part of a roll part, and when a steel plate contacts a roll part, oil content on the surface of a steel plate is made into both ends from the center part of a steel plate. It can be easily swept into the part. Therefore, a phenomenon generally called an edge drip phenomenon in which oil remains at both ends of the steel plate does not occur, and the oil on the surface of the steel plate including both ends of the steel plate can be uniformly extracted. Further, even in a steel plate in which a hole portion generally called a hollow material is formed, no oil remains on the outer periphery of the hole portion, and the oil on the surface of the steel plate can be uniformly extracted.

  In the third invention, the rotating outer diameter of the roll piece B constituting the roll portion changes from large to small as it approaches the center portion from the end portion of the roll portion. Therefore, when pressure is applied to the roll, the central part of the roll part is more easily deformed in the direction perpendicular to the longitudinal direction of the rotating shaft constituting the roll than the end part, and the shape of the diversified steel sheet Can be easily accommodated. That is, since the followability of the steel sheet to the roll part is improved, the contact property between the roll part and the steel sheet is improved, and in particular, a steel sheet generally called tailored blanking material obtained by laser wave welding of steel sheets having different thicknesses. However, when contacting the roll portion, no oil remains on the step and the step surface of the steel plate welded portion, and the oil on the surface of the steel plate can be uniformly extracted. Moreover, since the porosity of the center part of a roll part is high compared with an edge part, more oil can be stored in the inside of a roll part.

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

  As shown in FIGS. 1, 2, 3, 4A and 4D, the roll 1 is formed of a pedestal 2, a fastener 3, a plate 4, a plurality of roll pieces A5, and a roll piece B6. It is. Moreover, the roll part 51 is comprised from roll piece A5 and roll piece B6. A key 9 is formed on the outer periphery of the base 2 in the longitudinal direction. The pedestal 2 is not intended to suck up oil with a suction pump or the like, but has a hollow or through-hole for the purpose of weight reduction or the like, and has a substantially cylindrical shape with a solid structure. A roll portion 51 in which a plurality of roll pieces A5 and a roll piece B6 are overlapped is formed, and is attached by being clamped by a stopper 3 and a plate 4 from both sides. Further, a snap ring is used for the stopper 3. Further, as shown in FIG. 2, the roll piece A5 is formed in a substantially disk-like flat plate shape, and a hole portion 34 and a key groove 33 are formed in the center portion, and an edge portion 32 is formed in the outer peripheral portion. It is formed. Further, as shown in FIG. 3, the roll piece B6 is formed in a substantially disk-like flat plate shape, a hole 44 and a key groove 43 are formed in the center, and an edge 42 is formed in the outer periphery. It is formed. In addition, the roll part 51 is formed from the roll piece A5 of the total number used for the roll 1, and roll piece B6.

  Next, a manufacturing method of the roll 1 will be described. First, the roll piece A5 and the roll piece B6 are punched into a substantially disc-shaped flat plate shape. In addition, the rotation outer diameter of roll piece B6 is generally set smaller than the rotation outer diameter of roll piece A5. Next, a plurality of roll pieces A5 and roll pieces B6 punched into a substantially disc-like flat plate shape are overlapped, and the hole 34 of the roll piece A5 and the hole 44 of the roll piece B6 are penetrated through the base 2. The key groove 33 of the roll piece A5 and the key groove 43 of the roll piece B6 are fitted and inserted into the key 9 formed on the pedestal 2, and a predetermined length is obtained from the longitudinal direction of the pedestal 2 with a press machine. After being compressed only, it is clamped and fixed by the fastener 3 and the plate 4. Next, by leaving it for a predetermined time, the internal stress of the plurality of roll pieces A5 and roll pieces B6 overlapped is made uniform, and the edge portion 32 of the roll piece A5 is manufactured by cutting and polishing.

  The material of the roll piece A5 is formed of a double structure made of a nonwoven fabric and porous polyurethane having extremely fine bubbles, and the material of the fibers constituting the nonwoven fabric is nylon, polyester, polyethylene At least one of the above materials is used among polypropylene, spandex. The material is generally called artificial leather. Further, as the material of the roll piece A5, various nonwoven fabrics, woven fabrics, knitted fabrics, synthetic resin foams, elastomers, film-like compositions, and the like can be used in addition to the above materials.

  On the other hand, the roll piece B6 may be made of the same material as the roll piece A5 or may be made of a different material, and is not particularly limited. As the different material, for example, at least one kind of non-woven fabric, woven fabric, knitted fabric, synthetic resin foam, elastomer, film-like composition, resin sheet, or metal sheet can be used. In addition, when using the said different material, it is desirable to set the unit price of roll piece B6 lower than the unit price of roll piece A5.

  Further, the ratio of the number of stacked sheets of the roll piece B6 to the roll piece A5 may be constant as shown in FIGS. 4 (a) and 4 (e), or FIG. 4 (b), FIG. 4 (c), and FIG. 4 (f) may be regular and is not particularly limited. 4 (b) and 4 (f), the ratio of the number of layers of the roll piece B6 to the roll piece A5 changes from large to small as the end part 17 of the roll parts 61 and 91 approaches the center part 18. It is a form to do. In FIG. 4C, a plurality of section roll portions 72, 82, and 92 are formed in the roll portion 71, and the section roll portions 72, 82, and 92 are formed from the end portion 17 of the roll portion 71 to the center portion 18. The section roll portion A72, the section roll section B82, and the section roll section C92 are formed so that the ratio of the number of stacked sheets of the roll piece B6 to the roll piece A5 gradually changes from large to small as it approaches. is there. That is, the section roll portion A72 is configured such that the ratio of the number of stacked sheets of the roll piece B6 to the roll piece A5 is the largest, and then the section roll portion B82 and the section roll portion C92 become smaller in this order. In each section roll portion, the ratio of the number of stacked sheets of the roll piece B6 to the roll piece A5 is set to be constant.

  The rotating outer diameter of the roll piece B6 may be constant as shown in FIGS. 4 (a) to 4 (c), or as shown in FIGS. 4 (e) and 4 (f). It may change from large to small as it approaches the center 18 from the end 17 of 91. Moreover, it may change irregularly and is not specifically limited.

  The operation and action of the roll 1 in the present embodiment having the above-described configuration are as follows.

  The roll part 51 which comprises the roll 1 consists of the roll piece A5 currently formed in the substantially disc shape, and the roll piece B6 from which the rotation outer diameter differs from the said roll piece A5, The said roll piece A5 and the said roll piece B6 are A plurality of layers are stacked. Therefore, the core part 8 of the roll part 51 has the roll part A5 and the roll piece B6 laminated more densely than the surface part 7 of the roll part 51 in which only the roll piece A5 is laminated. Even if it has a strong clamping force and is formed with high hardness, the surface portion 7 can be formed with a lower hardness than the core portion 8. For this reason, the roll piece A5 and the roll piece B6 are not displaced during the rotation of the roll 1, and the surface part 7 of the roll part 51 is not uneven. Moreover, since the surface part 7 of the roll part 51 is excellent in the softness | flexibility compared with the core part 8 of the roll part 51, when the steel plate contacts the roll part 51, the roll 1 is flipped up by the steel plate. There is nothing. In particular, when a steel plate generally called a thick plate having a thickness of 1 mm or more is brought into contact with the roll portion 51, the roll 1 is not splashed up, and the oil content on the steel plate surface is uniformly distributed from the front end portion of the steel plate. Can be exploited.

  Moreover, the operation | movement and effect | action of the rolls 11, 21, and 41 in other embodiment are as follows.

  The roll portions 61, 71, 91 constituting the rolls 11, 21, 41 are such that the ratio of the number of stacked sheets of the roll piece B 6 to the roll piece A 5 is the center portion 18 from the end portion 17 of the roll portions 61, 71, 91. As it approaches, it changes from large to small. For this reason, the end 17 of the rolls 61, 71, 91 is more closely stacked with the roll piece B 6 than the center part 18 with respect to the roll piece A 5. In a steel plate washer, air pressure or hydraulic pressure is applied to the end portions 17 of the roll portions 61, 71, 91, and the strongest pressure is applied to the end portions 17 of the roll portions 61, 71, 91. The end portions 17 of the roll portions 61, 71, 91 are most prone to crushing, deterioration, shape deformation, and the like due to form changes. In the present invention, as described above, the end portions 17 of the roll portions 61, 71, and 91 have the roll pieces B 6 and the roll pieces A 5, which are densely laminated with respect to the roll pieces A 5. The roll piece B6 does not cause displacement, and the surface portion 7 of the end portion 17 of the roll portions 61, 71, 91 does not become uneven. Further, the central portion 18 of the roll portions 61, 71, 91 is superior in flexibility to the end portion 17 of the roll portions 61, 71, 91, and the steel plate contacts the roll portions 61, 71, 91. At that time, the oil on the surface of the steel plate can be easily swept away from the central portion of the steel plate to both ends. Therefore, a phenomenon generally called an edge drip phenomenon in which oil remains at both ends of the steel plate does not occur, and the oil on the surface of the steel plate including both ends of the steel plate can be uniformly extracted. Further, even in a steel plate in which a hole portion generally called a hollow material is formed, oil does not remain on the outer periphery of the hole portion, and the oil on the surface of the steel plate can be uniformly extracted.

  Moreover, the operation | movement and effect | action of the rolls 31 and 41 in other embodiment are as follows.

  The roll portions 81 and 91 constituting the rolls 31 and 41 change from large to small as the rotational outer diameter of the roll piece B6 approaches the center portion 18 from the end portion 17 of the roll portions 81 and 91. Therefore, when pressure is applied to the rolls 31, 41, the central portion 18 of the roll portions 81, 91 is in a direction orthogonal to the longitudinal direction of the rotation shafts constituting the rolls 31, 41, compared to the end portion 17. It can be easily deformed and can easily cope with diversified shapes of steel plates. That is, since the followability of the steel sheet to the roll parts 81 and 91 is improved, the contact between the roll parts 81 and 91 and the steel sheet is improved, and in particular, generally tailored blanking material obtained by laser wave welding of steel sheets having different thicknesses. When the steel plate referred to as is in contact with the roll portions 81 and 91, no oil remains on the step and the step surface of the steel plate welded portion, and the oil on the surface of the steel plate can be uniformly extracted. Further, since the central portion 18 of the roll portions 81 and 91 has a higher porosity than the end portion 17, more oil can be stored in the roll portions 81 and 91.

  The roll of the present invention mainly removes moisture, oil or chemical components adhering to the surface to be cleaned made of a steel plate, non-ferrous metal plate, resin plate, or film, exploits, cleans, and moisture on the surface to be cleaned. In addition to the purpose of applying an oil component or a chemical component, it can be widely and suitably used as a roll requiring high durability.
