Description

  The present invention is equipped with a roll for removing, squeezing, and cleaning liquids such as moisture, oil, or chemical components adhering to a steel plate, non-ferrous metal plate, resin plate, or film-like surface to be cleaned, and the roll. The present invention relates to a cleaning device.

  For this type of conventional roll, a nonwoven fabric roll, a rubber roll, etc. are generally used. For example, for a nonwoven fabric roll, a polymer elastic body is porous in a void of a nonwoven fabric in which ultrafine fibers are sterically entangled. There is a liquid-absorbing roll (Patent Document 1) in which a large number of disk-shaped materials made of a fibrous sheet filled with a structure are superimposed.

  Since the liquid absorption roll of patent document 1 is not equipped with the external device required in order to attract | suck a liquid, the roll part which consists of a nonwoven fabric layer will be in a liquid absorption saturated state gradually. The liquid removal function in a roll that does not include an external device necessary for sucking the liquid is a roll that is rotating while applying a certain pressure such as air pressure or hydraulic pressure via a compressor or the like. In the compression zone where the cleaning surface comes into contact with the surface to be cleaned and the pressure is compressed by pressure while contacting the surface to be cleaned while the roll is rotating In the open zone where the absorbed liquid is once released to the surface to be cleaned, and then the roll is released from compression by pressure, the liquid on the surface to be cleaned is sucked into the roll by the capillary action of the fibers forming the nonwoven fabric, and the roll And an intake / exhaust function composed of a mechanism that is discharged into the gap of the part. The dam function is a function expressed in a rubber roll or the like, but the suction / exhaust function is a function specific to the nonwoven fabric roll. That is, since the elastic polymer filled in the nonwoven fabric is elastically deformed, the porosity of the roll portion becomes 0% in the compression zone and is restored to the original porosity in the open zone. However, when the liquid is repeatedly absorbed and discharged from the gap of the roll part, the polymer elastic body comes into contact with the liquid and gradually swells to lower the elastic modulus, and the open zone Thus, the original porosity cannot be restored. For this reason, the entire volume of liquid sucked up by the capillary action of the fibers cannot be released into the gap portion of the roll portion where the porosity is reduced, and the roll portion becomes saturated with liquid absorption, and the liquid removal function is long. It had the problem of not lasting for a period. As for the relationship between the elastic modulus and swelling degree of the polymer elastic body, Flory's theory of rubber elasticity is known in which the elastic modulus is inversely proportional to the third power of the swelling degree.

  In order to solve the above-mentioned problem, a shaft main body having a liquid absorption function, a non-woven fabric roll composed of a non-woven fabric sheet crimped and superimposed on the shaft main body, and a vacuum pump communicated with the non-woven fabric roll via a pipe A liquid absorption method using a nonwoven fabric roll having a delivery and liquid absorption function, wherein the liquid absorption method is intended to increase the vacuum value due to suction resistance and the function of the capillary tube. The outer surface of the non-woven fabric roll in the non-woven fabric portion in the liquid-absorbing state through a plurality of through holes formed in the shaft main body in a staggered manner in the used state. By making the liquid absorption and liquid feeding capillary part effective in a substantially inverted conical shape toward the direction and acting so that a part of the vacuum suction force acts on the outer surface of the nonwoven fabric roll, Above The idle suction force and liquid absorption method using a nonwoven fabric roll has a structure to uniformly act on the outer surface of the nonwoven fabric roll, the liquid absorbing roll apparatus used in the liquid-absorbing method (Patent Document 2) has been devised.

Japanese Patent Application Laid-Open No. 61-262586 JP-A-7-120145

  The liquid absorption method using the nonwoven fabric roll of Patent Document 2 and the liquid absorption roll device used in this liquid absorption method are not limited to the dam function and the air suction / discharge function of the nonwoven fabric roll, and the liquid absorbed in the roll portion is vacuum Since the pump discharges to the outside of the nonwoven fabric roll through the through-hole, cavity, and through-hole, the liquid absorption saturation state of the roll portion is suppressed compared to the nonwoven fabric roll that does not have an external device necessary for liquid absorption. The liquid removal function is maintained for a long time. However, the nonwoven fabric roll is configured to suck the liquid only from one end of the shaft body, and the vacuum suction force is likely to vary. That is, the vacuum suction force is strong at one end of the shaft main body close to the vacuum pump, and the vacuum suction force is weak at the other end of the shaft main body away from the vacuum pump. Therefore, it has a problem that it is difficult to uniformly suck the liquid absorbed by the nonwoven fabric sheet.

  The above phenomenon is generally called friction energy loss. The liquid absorbed inside the non-woven fabric part becomes a fluid by the vacuum suction force, and is discharged to the outside of the non-woven fabric roll through the through hole, the hollow part, and the through hole, but when the fluid flows, Energy loss occurs due to friction caused by contact between the inner wall surface and fluid. If the moving distance of the fluid in the cavity is short, the energy loss is small and the vacuum suction force acts strongly. However, if the moving distance of the fluid is long, the energy loss is large and the vacuum suction force is weak.

  Further, one end of the shaft main body close to the vacuum pump is hollow, and the other end of the shaft main body away from the vacuum pump is solid, causing a weight difference at both ends of the shaft main body. For this reason, the rotational balance of the nonwoven fabric roll is poor, and the nonwoven fabric sheet is not easily slidably contacted with the surface to be cleaned.Therefore, the liquid cannot be uniformly removed from the surface to be cleaned, and a residue mark is likely to occur on the surface to be cleaned. He also had problems.

  The present invention solves the above-described conventional problems. The liquid absorbed in the roll portion is quickly and uniformly sucked and discharged to the outside of the roll. An object of the present invention is to provide a roll having excellent durability capable of uniformly removing, extracting and cleaning a liquid from a surface to be cleaned, and a cleaning apparatus equipped with the roll.

In order to solve the conventional problem, the roll of the invention of claim 1 removes liquid such as moisture, oil, or chemical components adhering to a steel plate, non-ferrous metal plate, resin plate, or film-like surface to be cleaned. In the roll for squeezing and washing, the roll has a roll part and a pedestal, and the pedestal has a main body part in which an opening is formed, and a joint part A and a joint part B connected to both ends of the main body part. The joint portion A and the joint portion B are formed with a hollow portion, the hollow portion is communicated with the opening, and the joint portion between the main body portion, the joint portion A, and the joint portion B is provided. In the vicinity, a gradually changing portion is formed so that an opening area of the opening is smaller than an opening area of a substantially central portion of the main body, and a fluid introduction groove is formed on the outer periphery of the main body. The fluid introduction groove communicates with the opening. Parts with the are opened, the roll portion is formed, the roll portion is Ri Oh is formed a plurality of rolls pieces of approximate annular consisting nonwoven is laminated, the fluid introduction groove, the hole is It is formed within the range of the vicinity of one end and the vicinity of the other end in the longitudinal direction of the established main body , and the pedestal penetrates in a hollow shape at the opening and the hollow. Therefore, the joint part A and the joint part B connected to both ends of the main body part can both be connected to a vacuum pump via a pipe. Accordingly, the liquid absorbed in the roll part can be sucked from both ends of the pedestal at the same time, so that the fluid is at substantially the same distance from the substantially central part in the longitudinal direction of the opening toward both ends of the pedestal. Therefore, the generation of frictional energy loss of the fluid is suppressed as much as possible, there is no variation in vacuum suction force, and the liquid absorbed in the roll part is quickly and uniformly sucked and discharged to the outside of the roll. To do. Therefore, the liquid absorption saturation state of the roll part is eliminated, and the service life of the roll can be prolonged.

  Since the joint part A and the joint part B constituting the pedestal both have a hollow part and are hollow, there is no weight difference at both ends of the pedestal, and the rotational balance of the roll is maintained. Therefore, since the roll portion is in sliding contact with the surface to be cleaned uniformly, the liquid can be uniformly removed from the surface to be cleaned, squeezed and cleaned.

  Since the gradually changing portion is formed in the vicinity of the joint portion of the main body portion and the joint portion A and the joint portion B constituting the base, the fluid sucked from the roll portion to the opening portion of the main body portion through the hole portion is Without flowing into the opening, it flows into the hollow portion formed in the joint portion A and the joint portion B along the inclined surface of the gradually changing portion, and is discharged to the outside of the roll. In addition, when the gradual change part which has an inclined surface is not formed in the both ends of a main-body part, reflux generate | occur | produces in the connection part of a main-body part, the joint part A, and the joint part B, and a liquid is an opening part of a main-body part. It becomes difficult to suck the liquid efficiently and reliably. Also, the load on the vacuum pump increases.

  A fluid introduction groove is formed on the outer periphery of the main body, and a hole communicating with the opening is opened in the fluid introduction groove. It is possible to uniformly flow from the hole to the opening via the fluid introduction groove. Therefore, the roll can suck the liquid absorbed in the roll part quickly and uniformly and discharge it to the outside of the roll as compared with the form in which the fluid introduction groove part is not formed on the outer periphery of the main body part. It becomes. In the roll of the present invention, since the fluid introduction groove is formed on the outer periphery of the main body constituting the pedestal, it is not necessary to provide a notch on the inner periphery of the roll piece, and the roll piece for the main body is not provided. There is no need for positioning.

The fluid introduction groove is formed in a range from the vicinity of one end in the longitudinal direction of the main body to the vicinity of the other end , and the fluid introduction groove is provided in the vicinity of both ends of the main body. Not formed. Therefore, the fluid generated by the vacuum suction force does not flow out of the roll from both ends of the main body, and the liquid absorbed by the roll becomes a fluid as a fluid introduction groove, hole, opening. And flows out of the roll reliably in the order of the hollow part. Therefore, there is no pressure loss, and the suction performance of the liquid from the roll part is greatly improved.

The roll of the invention of claim 2 is the roll of claim 1 in particular, wherein the fluid introduction groove is formed substantially parallel to the longitudinal direction of the main body, and the fluid sucked from the roll to the opening is It flows into the opening through the fluid introduction groove and the hole. Therefore, compared to the case where a fluid introduction groove is not formed on the outer periphery of the main body and only a hole is formed, fluid flows uniformly into the opening. This leads to an improvement in the suction performance of the liquid from the section. That is, since the fluid flows uniformly into the opening, the time when the liquid absorbed by the roll portion is discharged to the outside of the roll can be shortened, and the liquid can be more uniformly spread over the entire roll portion. , And uneven suction of the liquid from the roll portion can be suppressed.

The roll of the invention of claim 3 is the roll of claim 1 in which the fluid introduction groove is formed in an annular shape on the outer periphery of the main body, and the fluid sucked from the roll to the opening is fluid It flows into the opening through the introduction groove and the hole. Therefore, compared to the case where a fluid introduction groove is not formed on the outer periphery of the main body and only a hole is formed, fluid flows uniformly into the opening. This leads to an improvement in the suction performance of the liquid from the section. That is, since the fluid flows uniformly into the opening, the time when the liquid absorbed by the roll portion is discharged to the outside of the roll can be shortened, and the liquid can be more uniformly spread over the entire roll portion. , And uneven suction of the liquid from the roll portion can be suppressed.

The roll of the invention of claim 4 is the roll of claim 1 in particular, and the fluid introduction groove is formed by being spirally wound around the outer periphery of the main body, and is sucked into the opening from the roll. The fluid flows into the opening through the fluid introduction groove and the hole. Therefore, compared to the case where a fluid introduction groove is not formed on the outer periphery of the main body and only a hole is formed, fluid flows uniformly into the opening. This leads to an improvement in the suction performance of the liquid from the section. That is, since the fluid flows uniformly into the opening, the time when the liquid absorbed by the roll portion is discharged to the outside of the roll can be shortened, and the liquid can be more uniformly spread over the entire roll portion. , And uneven suction of the liquid from the roll portion can be suppressed.

The roll of the invention of claim 5 is the roll according to any one of claims 1 to 4 , wherein the ratio of the opening area of the fluid introduction groove to the outer periphery of the main body is substantially the center than the vicinity of the end of the main body. In the vicinity of the substantially central portion of the main body portion, more fluid flows along the fluid introduction groove portion and flows out to the opening portion through the hole portion. By the way, various widths of the steel plate, non-ferrous metal plate, resin plate, or film-like surface to be cleaned come into contact with and pass through the roll portion. The cleaning surface passes. Therefore, the vicinity of the substantially central portion of the roll portion is a portion where the liquid is absorbed most. Therefore, by adopting a configuration in which more fluid flows into the opening from the vicinity of the substantially central portion of the main body, the liquid suction performance from the roll is dramatically improved.

A cleaning apparatus according to a sixth aspect of the present invention includes a roll according to any one of the first to fifth aspects, a driving unit that rotationally drives the roll, and a joint portion A and a joint portion B that communicate with each other via a pipe. Since it has a vacuum pump that is equipped with a roll that can reliably remove, squeeze, and wash the liquid from the surface to be cleaned over a long period of time, excellent liquid removal performance is exhibited. . For this reason, the generation of residue marks in which liquid remains unevenly on the surface to be cleaned is suppressed, leading to improvement in the quality of the surface to be cleaned.

It is explanatory drawing of the washing | cleaning apparatus carrying the roll of this invention.

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

  The roll of Example 1 is demonstrated using FIGS. 1-4.

  1 and 2, the roll 1 includes a pedestal 3, a stopper 5, a plate 6, and a roll portion 2 including a plurality of roll pieces 4. The pedestal 3 is made of a metal material such as iron, the roll part 2 is formed on the outer periphery, the main body part 7 having the opening 10, and connected to both ends of the main body part 7, and the hollow part 11 is formed from a joint portion A8 having 11 and a joint portion B9. The roll part 2 is formed by laminating a plurality of roll pieces 4 on the outer periphery of the main body part 7 constituting the pedestal 3, and overlapping the roll part 2, and is sandwiched between the stopper 5 and the plate 6 from both sides. It is formed. A snap ring is used for the fastener 5.

2 and 4A, the main body portion 7 constituting the pedestal 3 has a plurality of fluid introduction groove portions 13 formed on the outer periphery so as to be substantially parallel to the longitudinal direction. The fluid introduction groove portion 13 is provided at six locations on the outer periphery of the main body portion 7 and is formed in the formation region L ₁ excluding the non-formation region L ₂ in the vicinity of both ends of the entire length in the longitudinal direction of the main body portion 7. It is formed within the range. The fluid introduction groove 13 has a plurality of circular holes 14 formed therein. The hole 14 communicates with the opening 10 of the main body 7. The shape of the hole 14 may be a polygonal shape such as an approximate triangle or an approximate quadrangle, or an irregular cross-sectional shape such as a star shape or a cross shape, in addition to a circular shape. The joint portion A8 and the joint portion B9 are provided with a hollow portion 11, and at one end portion, a screw portion 12 to which a rotary joint (not shown) is connected is formed, and the other Is connected to the end of the main body 7 via a joint 20 by welding. Accordingly, the opening 10 of the main body 7, the hollow portion 11 of the joint A8 and the joint B9 inevitably communicate with each other. The stopper 5 is fitted and inserted into the recess 19 formed in the joint A8 and the joint B9.

  Further, a gradually changing portion 21 having an inclined surface is formed in the vicinity of the joint portion 20 of the main body portion 7, the joint portion A8, and the joint portion B9. Therefore, the opening area of the opening 10 is smaller than the opening area of the substantially central portion of the main body 7 near the joint 20 of the main body 7 and the joint A8 and the joint B9.

  In FIG. 3, the roll piece 4 is composed of a substantially annular non-woven fabric 15 having a hole 17 at the center and a side edge 18 at the outer periphery. The nonwoven fabric 15 has a plurality of fibers 16. The roll unit 2 is formed from the total number of roll pieces 4 used for the roll 1. Although not shown in particular, in order to prevent displacement of the roll piece 4 with respect to the pedestal 3, a concave groove is formed in the inner circumference of the roll piece 4, and the outer circumference in the longitudinal direction of the main body portion 7 constituting the pedestal 3. The roll piece 4 may be laminated on the outer periphery of the main body 7 by attaching a convex key to the concave key and fitting and inserting the concave groove into the convex key.

  Next, a manufacturing method of the roll 1 will be described.

  First, a substantially cylindrical body portion 7 having a hole portion 14 and a fluid introduction groove portion 13 formed on the outer periphery and having an opening 10 is prepared. Next, the hollow joint portion A8 and the joint portion B9 having the hollow portion 11 in which the hollow portion 11 and the gradual change portion 21 are formed are inserted into both end portions of the main body portion 7, and are press-fitted or shrinked. At the same time, the main body portion 7, the joint portion A8, and the joint portion B9 are integrated through the joint portion 20 by welding to form the base 3. As long as the strength of the pedestal 3 is maintained, the connecting method of the main body 7, the joint A8, and the joint B9 may be a method such as screwing or bolting.

  Next, a flat non-woven fabric 15 having a plurality of fibers 16 is prepared, and the non-woven fabric 15 is made of a Thomson type or a laser cutter or the like, and a generally annular roll piece having a hole 17 and a side edge 18. Punch out to 4. Next, a plurality of roll pieces 4 are overlapped so that the hole portion 17 penetrates the base 3 and is laminated on the outer periphery of the main body portion 7. And after compressing only predetermined length with the press machine from the longitudinal direction of the base 3, the several roll piece 4 is pinched | interposed and fixed with the metal fitting 5 and the plate 6. FIG. Next, by leaving it to stand for a predetermined time, the internal stress of the plurality of roll pieces 4 overlapped is made uniform, the side edge 18 is cut and polished, and the roll is rolled on the outer periphery of the main body 7 constituting the base 3. The part 1 is formed and the roll 1 is manufactured.

  The hardness of the surface portion of the roll portion 2 is desirably set to about 40 ° to 95 °. When the hardness is less than 40 °, the hardness is too low, and the roll part 2 is worn early when the end face of the surface to be cleaned repeatedly contacts the roll part 2. On the other hand, if the hardness exceeds 95 °, the hardness is too high, the elasticity of the roll 1 is inferior, and it becomes difficult to effectively exhibit the dam function and the suction / discharge function. In addition, hardness represents the hardness of a substance and is the hardness measured by the durometer hardness test described in the hardness test method of JISK6253 vulcanized rubber and thermoplastic rubber.

  The diameter of the hole 14 and the width and depth of the fluid introduction groove 13 are not particularly limited. For example, the diameter of the hole 14 is about 1 to 8 mm, and the width of the fluid introduction groove 13 is 2 to 30 mm. The depth and the depth are desirably set to about 0.1 to 5 mm, and the width of the fluid introduction groove 13 needs to be set larger than the diameter of the hole 14. When the diameter of the hole 14 is less than 1 mm, the diameter is too small to efficiently flow the fluid into the opening 10, and when the diameter exceeds 8 mm, the diameter is too large to suck the fluid per hole. Becomes weaker. Further, when the width of the fluid introduction groove 13 is less than 2 mm, the width is too narrow to allow the fluid to flow efficiently, and when it exceeds 30 mm, it is too wide to form the fluid introduction groove 13. If the depth of the fluid introduction groove 13 is less than 0.1 mm, the fluid cannot flow efficiently because it is too shallow, and if it exceeds 5 mm, it is too deep to form the fluid introduction groove 13.

  Next, some methods for manufacturing the nonwoven fabric 15 constituting the roll piece 4 will be described.

  In the first method, a plurality of fibers 16 are accumulated in a flat plate shape to form a cloth-like body, a plurality of the cloth-like bodies are overlapped, and then a special needle is pierced to entangle in three dimensions. A combined nonwoven fabric 15 is obtained. The above manufacturing method is generally called needle punching. The cloth-like body is called a web. The obtained nonwoven fabric 15 is impregnated in a polyurethane solution, and the nonwoven fabric 15 is filled with polyurethane. Next, the nonwoven fabric 15 filled with polyurethane is immersed in water, carbon dioxide is injected into the water, and carbonic acid foaming is performed, whereby a flat plate made of the nonwoven fabric 15 and a porous polyurethane having extremely fine bubbles is formed. Form a double structure. For the fibers 16 forming the nonwoven fabric 15, polyester fibers, nylon fibers, spandex fibers also called urethane elastic yarns, etc. are used alone or in combination.

  In the second method, a plurality of fibers 16 are accumulated in a flat plate shape to form a web that becomes a cloth-like body, and a nonwoven fabric 15 entangled three-dimensionally by needle punching is obtained. With respect to the obtained nonwoven fabric 15, a polymer elastic body blended with a crosslinking agent is attached using a method such as spraying, dipping, impregnation and the like, and the fibers 16 forming the nonwoven fabric 15 are bonded by heating. The nonwoven fabric 15 obtained by the above manufacturing method is generally called a chemical bond method nonwoven fabric. For the fibers 16 forming the nonwoven fabric 15, natural fibers such as cotton, rayon and cellulose, and synthetic fibers such as polyester, nylon and acrylic are used alone or in combination. In addition, nitrile rubber, acrylic rubber, styrene rubber, urethane rubber, acrylic resin, urethane resin and the like are used alone or in combination for the polymer elastic body. The crosslinking agent is blended for the purpose of forming a bridge structure between the molecules of the polymer elastic body and imparting further excellent elasticity to the polymer elastic body. Trimethylolmelamine, hexamethylol Melamine resins such as melamine, isocyanate resins such as blocked isocyanate, and epoxy resins such as aliphatic epoxy can be used alone or in combination.

  The third method melts and spins synthetic resins such as polyamide resin, polyester resin, polyethylene resin, and polypropylene resin, and entangles the fibers 16 by jetting a high-pressure water flow of about 100 to 150 kgf to the obtained synthetic fibers. Combine. Next, a non-woven fabric 15 obtained by the above-described manufacturing method is formed by adhering a polymer elastic body containing a cross-linking agent to the fibers 16 using a method such as spraying, dipping or impregnation, and heating to form the non-woven fabric 15. 15 is generally called a hydroentangled nonwoven fabric.

  The manufacturing method of the nonwoven fabric 15 shown above is a representative example. In addition to the above, for example, a fiber 16 is formed by continuously spinning a hot-melt synthetic resin, and the fiber 16 is collected while being drawn. A spunbond method in which the fibers 16 are bonded together to form a nonwoven fabric 15 by being accumulated on a net and pressurized with a hot roll, and when a hot-melt synthetic resin is discharged from the spinneret, it is spun with high-temperature air and collected. When the synthetic resin is dissolved in a low-boiling solvent such as methylene chloride and chlorofluorocarbon, which is formed by bonding the heated fibers 16 to form the nonwoven fabric 15, and the fibers 16 are spun in a heated and pressurized state from the spinneret. At the same time, the low-boiling solvent is volatilized, the fibers 16 are accumulated on a collection net, pressed by a hot roll, and the fibers 16 are bonded to form a nonwoven fabric 15; a plurality of synthetic resins having different melting points; A fiber bond method or thermal bond in which a synthetic resin having a higher melting point is spun to form a fiber 16 and the nonwoven fabric 15 is formed by adhering the fiber 16 using the molten synthetic resin having a lower melting point as a binder. You may use the nonwoven fabric 15 manufactured by the method etc. When the nonwoven fabric 15 is formed on the roll 1, it is strong against repeated contact of the surface to be cleaned, and the fibers 16 are not easily frayed. Compared to the case where other fabrics such as woven fabric and knitted fabric are used for the roll 1. The durability of the roll 1 is improved.

  The selection of the nonwoven fabric 15 used for the roll piece 4 is appropriately determined in consideration of the ambient temperature in which the roll 1 is used, the use conditions such as the properties of the liquid to be removed, the cost, and the like.

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

  The roll 1 has a roll part 2 and a pedestal 3, and the pedestal 3 has a main body part 7 in which an opening 10 is formed, a joint part A8 connected to both ends of the main body part 7, and a joint part B9. The joint portion A8 and the joint portion B9 are formed with a hollow portion 11, and the hollow portion 11 is communicated with the opening portion 10. The main body portion 7, the joint portion A8, and the vicinity of the joint portion 20 of the joint portion B9 are open portions. The gradually changing portion 21 having an inclined surface is formed so that the opening area of 10 is smaller than the opening area of the substantially central portion of the main body portion 7, and the fluid introduction groove portion 13 is formed on the outer periphery of the main body portion 7. The fluid introduction groove 13 is provided with a hole 14 communicating with the opening 10, a roll part 2 is formed, and the roll part 2 is formed by laminating a plurality of substantially annular roll pieces 4 made of nonwoven fabric 15. As the surface to be cleaned is attached, Upon contact with Lumpur unit 2, the dam function and the intake function of the roll 1, the liquid is removed. The roll 1 discharges liquid to the inside of the roll part 2 and discharges it to the outside by the capillary action of the fibers 16 included in the nonwoven fabric 15 constituting the roll part 2 by the suction / discharge function. In the roll 1, a hollow portion 11 is formed in the joint portion A8 and the joint portion 9 constituting the base 3, and an opening portion 10 is formed in the main body portion 7. The hollow portion 11 and the opening portion 10 communicate with each other. . A rotary joint (not shown) is connected to the screw part 12 of the joint part A8 and the joint part B9, a vacuum pump (not shown) is connected via a pipe (not shown), and the vacuum pump is operated to obtain a vacuum suction force. When a negative pressure is applied, a negative pressure is applied to the roll part 2, and the liquid absorbed by the roll part 2 becomes a fluid, and the fluid is a fluid introduction groove part 13 and a hole part 14 as indicated by a two-dot chain line arrow in FIG. Through the hollow portion 11 formed in the joint portion A8 and the joint portion B9 and sucked to the outside of the roll 1 and discharged. Therefore, since the liquid absorption saturation state of the roll part 2 is eliminated and the suction / exhaust function is maintained, the roll 1 can reliably remove, extract and wash the liquid adhering to the surface to be cleaned over a long period of time. . The timing for operating the vacuum pump may be either when the roll 1 is operating or when it is not operating.

  In the roll 1 of the present invention, since the pedestal 3 is formed through the opening 10 and the hollow portion 11 so as to penetrate in a hollow shape, the joint portion A8 connected to both ends of the main body portion 7 and the joint portion Both B9 can be connected to a vacuum pump via a pipe. Therefore, since the liquid absorbed by the roll part 2 can be simultaneously sucked from both ends of the pedestal 3, the fluid is substantially directed from the substantially central part in the longitudinal direction of the opening 10 toward both ends of the pedestal 3. Since they move at the same distance, the generation of frictional energy loss of the fluid is suppressed as much as possible, the vacuum suction force does not vary, and the liquid absorbed by the roll unit 2 is sucked quickly and uniformly. It can be discharged outside the roll 1.

  The joint part A8 and the joint part B9 constituting the pedestal 3 both have the hollow part 11 and are hollow, so that there is no weight difference at both ends of the pedestal 3, and the rotation balance of the roll 1 is maintained. Retained. Therefore, since the roll part 2 is in sliding contact with the surface to be cleaned uniformly, the liquid can be uniformly removed, exploited and cleaned from the surface to be cleaned.

  Since the gradually changing portion 21 is formed in the vicinity of the joint portion 20 of the body portion 7 and the joint portion A8 and the joint portion B9 constituting the base 3, the roll portion 2 and the body portion 7 are connected to each other through the hole portion 14. The liquid sucked into the opening portion 10 flows into the hollow portion 11 formed in the joint portion A8 and the joint portion B9 along the inclined surface of the gradual change portion 21 without staying in the opening portion 10, and rolls 1 is discharged to the outside.

Since the fluid introduction groove 13 is formed in a range between the vicinity of one end and the vicinity of the other end in the longitudinal direction of the main body 7, that is, in the formation region L ₁ , neighborhood, that is, non-forming region L ₂ is not formed fluid introduction groove 13. Therefore, the fluid generated by the vacuum suction force does not flow out from the both ends of the main body portion 7 to the outside of the roll 1, and the liquid absorbed by the roll portion 2 becomes fluid and becomes the fluid introduction groove portion 13, hole The part 14, the opening 10, and the hollow part 11 are reliably discharged out of the roll 1 in this order. Therefore, there is no pressure loss, and the suction performance of the liquid from the roll unit 2 is greatly improved.

  Since the fluid introduction groove portion 13 is formed substantially parallel to the longitudinal direction of the main body portion 7, the fluid sucked from the roll portion 2 to the opening portion 10 is opened through the fluid introduction groove portion 13 and the hole portion 14. 10 flows. Therefore, compared with the case where the fluid introduction groove portion 13 is not formed on the outer periphery of the main body portion 7 and the pedestal 3 in which only the hole portion 14 is formed is used, the fluid uniformly enters the opening portion 10. Since it flows in, it leads to the improvement of the suction performance of the liquid from the roll part 2. That is, since the fluid flows uniformly into the opening 10, the time when the liquid absorbed by the roll 2 is discharged to the outside of the roll 1 can be shortened, and the entire area of the roll 2 can be reduced. The liquid can be sucked more uniformly, and the suction unevenness of the liquid from the roll unit 2 can be suppressed.

  Next, the roll 1 in other embodiment is demonstrated using FIG.4 (b).

In FIG. 4B, the pedestal 3 a has a plurality of fluid introduction grooves 13 a and 13 b formed on the outer periphery so as to be substantially parallel to the longitudinal direction of the main body 7. The fluid introduction groove 13a is provided at six locations on the outer circumference of the main body 7 and is formed in the formation region L ₁ excluding the non-formation region L ₂ in the vicinity of both ends of the entire length of the main body 7 in the longitudinal direction. It is formed by intensive formation region L ₃ and. In addition, the fluid introduction groove 13b is provided at six locations on the outer periphery of the main body 7 between adjacent fluid introduction grooves 13a, and in the vicinity of both ends of the entire length of the main body 7 in the longitudinal direction. The non-formation region L ₂ and the concentrated formation region L ₃ at the substantially central portion of the main body 7 excluding the formation region L ₁ are formed. Therefore, in the concentrated formation region L ₃ , the fluid introduction groove portions 13 a and 13 b are formed at 12 positions on the outer periphery of the main body portion 7, and the ratio of the opening areas of the fluid introduction groove portions 13 a and 13 b is the formation region. thus towards the centralized formation region L ₃ is greater than L _1. A plurality of circular holes 14 are formed in the fluid introduction grooves 13a and 13b. Further, one end of each of the joint portion A8 and the joint portion B9 is connected to the end portion of the main body portion 7 via a joint portion 20 by welding to constitute a base 3a. The stopper 5 is fitted and inserted into the recess 19 formed in the joint A8 and the joint B9.

  The operation and action of the roll 1 in which the roll portion 2 is formed on the outer periphery of the main body portion 7 using the pedestal 3a configured as described above are as follows.

In the roll 1, the ratio of the opening area of the fluid introduction grooves 13 a and 13 b to the outer periphery of the main body 7 is larger in the concentrated formation region L ₃ in the substantially central portion than in the formation region L ₁ in the vicinity of the end of the main body portion 7. Since it is large, more fluid flows along the fluid introduction grooves 13 a and 13 b in the vicinity of the substantially central portion of the main body 7 and flows out to the opening 10 through the hole 14. By the way, steel plates, non-ferrous metal plates, resin plates, or film-like surfaces to be cleaned come in contact with and pass through the roll portion 2 with various widths. The surface to be cleaned passes. Therefore, the vicinity of the substantially central portion of the roll part 2 is a place where the liquid is absorbed most. Therefore, by adopting a form in which more fluid flows into the opening 10 from the vicinity of the substantially central portion of the main body portion 7, the liquid suction performance from the roll portion 2 is dramatically improved.

  The roll in Example 2 is demonstrated using Fig.5 (a) and FIG.5 (b). In addition, about the same member as the said Example 1, the same number is attached | subjected and the detailed description is abbreviate | omitted.

In FIG. 5A, the main body 27 constituting the pedestal 23 has a plurality of annular fluid introduction grooves 33 formed on the outer periphery. The fluid introduction groove portions 33 are provided at five locations on the outer periphery of the main body portion 27, and are formed in the formation region L ₄ excluding the non-formation region L ₅ in the vicinity of both end portions of the entire length in the longitudinal direction of the main body portion 27. It is formed within the range. A plurality of circular holes 34 are formed in the fluid introduction groove 33. The hole 34 communicates with the opening 10 of the main body 27. The shape of the hole 34 may be a circular shape, a polygonal shape such as a general triangle or a general quadrangle, or a modified cross-sectional shape such as a star shape or a cross shape. The joint portion A28 and the joint portion B29 are provided with the hollow portion 11, and at one end portion thereof, a screw portion 12 to which a rotary joint (not shown) is connected is formed. Are connected to both end portions of the main body 27 via a joint 40 by welding. Therefore, the opening 10 of the main body 27 and the hollow portion 11 of the joint A28 and the joint B29 are inevitably communicated. The stopper 5 is fitted and inserted into the recess 39 formed in the joint A28 and the joint B29.

  The operation and action of the roll 1 in which the roll part 2 is formed on the outer periphery of the main body part 27 using the base 23 configured as described above are as follows.

Fluid introduction groove 33 is in the range of the vicinity of the neighborhood and the other end portion of the one end in the longitudinal direction of the main body portion 27, that is formed in the formation region L _4, both ends of the main body portion 27 neighborhood, that is, non-forming region L ₅ is not formed fluid introduction groove 33. Therefore, the fluid generated by the vacuum suction force does not flow out from the both ends of the main body 27 to the outside of the roll 1, and the liquid absorbed by the roll 2 becomes a fluid and becomes the fluid introduction groove 33, hole The portion 34, the opening 10, and the hollow portion 11 are reliably discharged out of the roll 1 in this order. Therefore, there is no pressure loss, and the suction performance of the liquid from the roll unit 2 is greatly improved.

  Since the fluid introduction groove portion 33 is formed in an annular shape on the outer periphery of the main body portion 27, the fluid sucked from the roll portion 2 to the opening portion 10 passes through the fluid introduction groove portion 33 and the hole portion 34. Flow into. Therefore, compared with the case where the fluid introduction groove portion 33 is not formed on the outer periphery of the main body portion 27 and the pedestal 23 in which only the hole portion 34 is formed is used, the fluid uniformly enters the opening portion 10. Since it flows in, it leads to the improvement of the suction performance of the liquid from the roll part 2. That is, since the fluid flows uniformly into the opening 10, the time when the liquid absorbed by the roll 2 is discharged to the outside of the roll 1 can be shortened, and the entire area of the roll 2 can be reduced. The liquid can be sucked more uniformly, and the suction unevenness of the liquid from the roll unit 2 can be suppressed.

  Next, the roll 1 in other embodiment is demonstrated using FIG.5 (b).

In FIG. 5B, the base 23 a has a plurality of annular fluid introduction groove portions 33 a and 33 b formed on the outer periphery of the main body portion 27. Fluid introduction groove 33a, of the total length over the longitudinal direction of the main body 27, and the non-formation region L ₅ in the vicinity of both end portions, the range of formation area L ₄ at two positions, except the concentration forming area L ₆ in the substantially central portion Two are formed inside. In addition, the fluid introduction groove 33b has a concentrated formation region L at a substantially central portion of the main body 27 excluding the non-formation region L ₅ and the formation region L ₄ in the vicinity of both ends of the entire length in the longitudinal direction of the main body 27. Three are formed at ₆ . Accordingly, the fluid introduced groove 33a, the ratio of the opening area of the 33b would towards intensive formation region L ₆ is greater than the formation region L _4. A plurality of circular holes 34 are formed in the fluid introduction grooves 33a and 33b. Further, one end of each of the joint portion A28 and the joint portion B29 is connected to the end portion of the main body portion 27 via a joint portion 40 by welding, thereby forming a base 23a. The stopper 5 is fitted and inserted into the recess 39 formed in the joint A28 and the joint B29.

  Using the pedestal 23a configured as described above, the operation and action of the roll 1 in which the roll part 2 is formed on the outer periphery of the main body part 27 are as follows.

In the roll 1, the ratio of the opening area of the fluid introduction grooves 33 a and 33 b to the outer periphery of the main body 27 is larger in the concentrated formation region L ₆ in the substantially central portion than in the formation region L ₄ in the vicinity of the end of the main body 27. Since it is large, more fluid flows along the fluid introduction groove 33 b in the vicinity of the substantially central portion of the main body 27 and flows out to the opening 10 through the hole 34. By the way, steel plates, non-ferrous metal plates, resin plates, or film-like surfaces to be cleaned come in contact with and pass through the roll portion 2 with various widths. The surface to be cleaned passes. Therefore, the vicinity of the substantially central portion of the roll part 2 is a place where the liquid is absorbed most. Therefore, by adopting a configuration in which more fluid flows into the opening 10 from the vicinity of the substantially central portion of the main body 27, the liquid suction performance from the roll unit 2 is dramatically improved.

  The roll of Example 3 is demonstrated using FIG.6 and FIG.7. Detailed description of the same members as those in the first and second embodiments will be omitted.

  In FIG. 6, the roll 41 includes a pedestal 43, a stopper 45, a plate 46, and a roll portion 42 including a plurality of generally annular roll pieces 44. The pedestal 43 is made of a metal material such as iron, and the main body portion 47 formed with the roll portion 42 on the outer periphery has a substantially cylindrical shape having openings 50, and joint portions A 48 connected to both ends of the main body portion 47, The joint portion B49 has a hollow shape having a hollow portion 51, and a screw portion 52 to which a rotary joint (not shown) is connected is formed at one end portion of each. The opening part 50 which the main-body part 47 has, and the hollow part 51 which the joint part A48 and the joint part B49 have communicated. The roll portion 42 is formed by laminating a plurality of roll pieces 44 on the outer periphery of the main body portion 47 constituting the pedestal 43 and overlapping them, and is sandwiched between the metal fittings 45 and the plate 46 from both sides. It is formed. A snap ring is used for the fastener 45. Further, a gradually changing portion 31 having an inclined surface is formed in the vicinity of the joint portion 30 of the main body portion 47, the joint portion A48, and the joint portion B49.

In FIG. 7, the main body portion 47 constituting the pedestal 43 is formed with two fluid introduction groove portions 53 having different inclination directions spirally wound around the outer periphery and the two fluid introduction groove portions 53. A plurality of circular holes 54 are provided at the intersections in a zigzag pattern. If the fluid is delivered, the setting position of the hole 54 is not limited to the intersection of the two fluid introduction grooves 53, and can be provided at any position of the fluid introduction groove 53. In addition to a circle, it may have a polygonal shape such as an approximate triangle or an approximate quadrangle, or an irregular cross-sectional shape such as a star shape or a cross shape. The hole 54 communicates with the opening 50 of the main body 47 as shown in FIG. The fluid introduction groove 53 is formed in the range of the formation region L ₇ excluding the non-formation region L ₈ in the vicinity of both ends of the entire length of the main body 47 in the longitudinal direction. In addition, one end of each of the joint portion A48 and the joint portion B49 is connected to the end portion of the main body portion 47 via the joint portion 30 by welding, so that a pedestal 43 is configured. A stopper 45 is fitted and inserted into the recess 59 formed in the joint A48 and the joint B49.

  The operation and action of the roll 41 configured as described above are as follows.

  The roll 41 has a hollow shape in which both a joint portion A48 and a joint portion B49 connected to the main body portion 47 have a hollow portion 51, and a rotary joint (not shown) is connected to the screw portion 52 of the joint portion A48 and the joint portion B49. When a vacuum pump (not shown) is connected via a pipe (not shown) and the vacuum pump is operated to apply a vacuum suction force, negative pressure is applied to the roll part 42 and absorbed by the roll part 42. The liquid thus formed becomes a fluid, and the fluid flows into the opening 50 through the fluid introduction groove 53 and the hole 54 as shown by a two-dot chain arrow in FIG. 6, and is formed in the joint A48 and the joint B49. The air is sucked from the hollow portion 51 to the outside of the roll 41 and discharged. Therefore, since the liquid absorption saturation state of the roll part 42 is eliminated and the suction / exhaust function is maintained, the roll 41 can reliably remove, extract and wash the liquid adhering to the surface to be cleaned over a long period of time. .

Fluid introduction groove 53 is in the range of the vicinity of the neighborhood and the other end portion of the one end in the longitudinal direction of the main body portion 47, that is formed in the formation region L _7, both ends of the main body portion 47 neighborhood, that is, non-forming region L ₈ is not formed fluid introduction groove 53. Therefore, the fluid generated by the vacuum suction force does not flow out from the both ends of the main body 47 to the outside of the roll 41, and the liquid absorbed by the roll portion 42 becomes fluid and becomes the fluid introduction groove 53, hole The part 54, the opening 50, and the hollow part 51 flow out to the outside of the roll 41 without fail. Therefore, there is no pressure loss, and the suction performance of the liquid from the roll part 42 is greatly improved.

  Since the fluid introduction groove portion 53 is formed by being spirally wound around the outer periphery of the main body portion 47, the fluid sucked from the roll portion 42 into the opening portion 50 passes through the fluid introduction groove portion 53 and the hole portion 54. Into the opening 50. For this reason, the fluid introduction groove 53 is not formed on the outer periphery of the main body 47, and the fluid is uniformly introduced into the opening 50 as compared with the case where the pedestal 43 having only the hole 54 is used. Since it flows in, the suction performance of the liquid from the roll part 42 is improved. That is, since the fluid flows uniformly into the opening 50, the time when the liquid absorbed by the roll part 42 is discharged to the outside of the roll 41 can be reduced, and the entire area of the roll part 42 can be reduced. The liquid can be sucked more uniformly, and the suction unevenness of the liquid from the roll part 42 can be suppressed.

  The cleaning apparatus of Example 4 will be described with reference to FIG. In addition, in order to make description of a structure easy, suppose that illustration and description of the bearing part of each component and a support component are abbreviate | omitted. Further, the roll is used for removing oil adhering to the steel plate.

  The rolls 61a and 61b are installed in a pair on the cleaning device 60, and a constant pressure is applied to both ends of the base 63 of the roll 61a located at the upper part, that is, the joint part A68 and the joint part B69. A piece-shaped steel plate 70, which is rotationally driven in the direction of the arrow and has oil (not shown) attached on both sides, is fed in the direction of the white arrow between the upper roll 61a and the lower roll 61b. Further, a rotary joint 66 is inserted into the end portions of the joint portion A68 and the joint portion B69, and is connected to a vacuum pump 67 through a pipe 65. The upper roll 61 a removes oil from the surface of the steel plate 70, and the lower roll 61 b removes oil from the back surface of the steel plate 70. The steel plate 70 to which the oil component has adhered comes into contact with the roll unit 62, and the oil component is sucked up by the roll unit 62 and discharged into the gap of the roll unit 62 due to the capillary action of the fibers of the nonwoven fabric constituting the roll unit 62. The rolls 61a and 61b are the same as any of the rolls 1 and 41 of Examples 1 to 3 described above.

  In the state of the rolls 61a and 61b as described above, when the vacuum pump 67 is operated to apply a vacuum suction force, a negative pressure is applied to the roll part 62, and the oil component absorbed by the roll part 62 becomes a fluid, The fluid passes through the fluid introduction groove and the hole, flows into the opening, is sucked to the outside of the rolls 61a and 61b through the pipe 65 from the hollow portion formed in the joint A68 and the joint B69, and is discharged. Is done. The fluid is sent again to the cleaning oil tank through a pipe (not shown) via a filter (not shown) by the vacuum pump 67. Therefore, since the liquid absorption saturation state of the roll part 62 is eliminated and the suction / discharge function is maintained, the rolls 61a and 61b can reliably remove the oil adhering to the steel plate 70 over a long period of time.

  The operation and action of the cleaning device 60 configured as described above are as follows.

  Since the cleaning device 60 is equipped with rolls 61a and 61b that can reliably remove oil from the steel plate 70 over a long period of time, excellent oil removal performance is exhibited. For this reason, the generation of residue marks in which oil remains unevenly on the steel plate 70 is suppressed, and the quality of the steel plate 70 can be improved.

  The roll of the present invention is mainly used for the purpose of removing, squeezing, and cleaning liquids such as moisture, oil, or chemical components adhering to the steel plate, non-ferrous metal plate, resin plate, or film-like surface to be cleaned. As a roll that requires high liquid removal performance, it can be used widely and suitably.
