Description

  The present invention is equipped with a roll for removing, squeezing, and cleaning liquids such as 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 this roll. The present invention relates to a cleaning device.

  Regarding conventional rolls and cleaning devices of this type, non-woven fabric rolls, rubber rolls and the like are generally used, and rolls as described above are mounted on the cleaning device. There is a liquid-absorbing roll (Patent Document 1) in which a large number of disk-like materials made of a fibrous sheet in which a macromolecular elastic body is filled with a porous structure are overlapped in a void of a nonwoven fabric in which fibers are entangled three-dimensionally. is there.

  Since the liquid absorption roll of patent document 1 is not equipped with the external device required for liquid absorption, the roll part which consists of a nonwoven fabric layer will be in a liquid absorption saturated state gradually. The liquid removal function for rolls that do not have external devices necessary for liquid absorption is to wash the liquid by rotating it with a drive means while applying constant pressure such as air pressure and hydraulic pressure to the roll via a compressor. In the dam function that flows away from both ends of the surface and the compression zone where the roll is compressed by pressure while rotating, the liquid absorbed in the gap of the roll portion is once released to the surface to be cleaned, and then the roll is compressed by pressure In the open zone that is opened from, the liquid on the surface to be cleaned is sucked up to the roll part by the capillary action of the fibers forming the nonwoven fabric, and is constituted by the air sucking and discharging function released into the gap part of the roll 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 pressure applied to the roll is low, the liquid sucked into the gap of the roll part in the open zone cannot discharge the entire amount of liquid to the outside of the roll in the compression zone, and the liquid in the gap part. Remains. While repeating the above operation, liquid gradually accumulated in the gap of the roll part, and finally the roll part was in a liquid absorption saturation state, and there was a problem that the liquid removal performance did not last for a long time. . In addition, in the open zone, when a high pressure is applied to the roll so that the entire amount of the liquid absorbed in the gap portion of the roll portion can be discharged, the surface portion of the roll portion is worn early, and the durability of the roll is reduced. It will be extremely inferior.

  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.

Also, a shaft body provided with a through hole and a cavity, a roll body having a number of porous holes for capillary action and water absorption provided in the shaft body, and a vacuum connection piping system provided in the communication hole of the shaft body In a draining method for sucking and draining the fluid of the object to be processed by vacuum suction using a liquid suction roll comprising: a water film formed on the inner wall surface of the cavity, a layered water film, a water wall, etc. The drainage function of the high-speed liquid-absorbing roll is designed to restore the drainage function by vacuum suction by breaking the basin with accelerated suction by intermittent forced introduction of external gas and opening the inner wall through-hole. There is a recovery method and a drainage device (Patent Document 3).

  The liquid absorption method using the nonwoven fabric roll of Patent Document 2 and the liquid absorption roll device used for this liquid absorption method are absorbed into the void portion of the nonwoven fabric portion in addition to the dam function and the absorption / exhaustion function of the nonwoven fabric roll, In the compression zone in function, the liquid that is not discharged to the outside of the roll and remains in the gap of the nonwoven fabric is discharged to the outside of the nonwoven fabric roll through the through holes, cavities, and through holes by the vacuum pump. Compared to a nonwoven fabric roll that does not have an external device necessary for liquid absorption as shown in Document 1, the liquid absorption saturation state of the nonwoven fabric portion is suppressed, and the liquid removal performance is maintained for a long period of time. However, it is necessary to newly introduce an external device such as a vacuum pump, which has a problem of increasing the capital investment cost.

  Moreover, the liquid discharged | emitted outside the nonwoven fabric roll will be attracted | sucked to the vacuum pump apparatus side. Although the discharged liquid is prevented from flowing into the vacuum pump device by a filter or the like, a part of the discharged liquid passes through the filter or the like and flows into the vacuum pump device, and the vacuum suction force gradually decreases. At the same time, since the vacuum pump is likely to break down, there is a problem that the running cost of the roll such as the purchase cost of the filter is increased in addition to the maintenance cost or the repair cost of the vacuum pump.

  Furthermore, the outer surface of the non-woven fabric portion is made effective by acting a liquid absorption and liquid feeding capillary portion in a substantially inverted cone shape toward the outer surface of the non-woven fabric roll inside the non-woven fabric portion in the liquid absorption state by a vacuum pump. In addition, foreign materials such as high viscosity components in the liquid and / or metal powder such as iron powder and aluminum powder mixed in the liquid, dust, etc., are actively attached, causing the surface of the nonwoven fabric to be clogged. There is also a problem that the function of sucking and discharging the roll is hindered.

  The method for recovering the drainage function of the high-speed liquid-absorbing roll of Patent Document 3 and the drainage device need to be provided with a converging portion in the hollow portion of the shaft body, or to provide an umbrella-like spacer, etc. Therefore, the production of the shaft main body is difficult and time-consuming, leading to a problem that the cost of the roll main body is increased.

  SUMMARY OF THE INVENTION The present invention solves the above-described conventional problems, and provides a roll that can reliably remove, extract, and wash the liquid adhering to the surface to be cleaned over a long period of time, and a cleaning device equipped with the roll. The purpose is to provide a low cost and low cost.

  In order to solve the above-mentioned conventional problems, the roll of the invention of claim 1 is provided with a liquid such as 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. In the roll for removal, exploitation, 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 connected to both ends of the main body part. B, the joint portion A and / or the joint portion B is formed with a hollow portion, the hollow portion is communicated with the opening portion, and the roll portion made of a nonwoven fabric is provided on the outer periphery of the main body portion. The fluid diffusion groove is formed, and the fluid diffusion groove is formed with a hole communicating with the opening. The surface to be cleaned which is attached with the liquid is in contact with the roll. Then roll dam The performance and intake functions, liquid is removed. The roll discharges liquid to the inside of the roll part and discharges it to the outside by the capillary action of the fibers of the nonwoven fabric constituting the roll part by the suction / discharge function. While repeating the suction / discharge function, the roll portion gradually becomes saturated with liquid absorption. By the way, in the roll of the present invention, a hollow portion is formed in the joint portion A and / or the joint portion B constituting the pedestal, and an opening portion is formed in the main body portion, and the hollow portion and the opening portion communicate with each other. When a compressor is connected to the joint part A and / or the joint part B via a pipe and a compressed fluid is ejected from the compressor, the compressed fluid is formed into a hollow part formed in the joint part A and / or the joint part B via the pipe. Then, it flows in the order of openings formed in the main body. When the compressed fluid fills the opening, the fluid flows into the fluid diffusion groove through the hole formed on the outer periphery of the main body so as to communicate with the opening, and then uniformly flows out to the roll and is absorbed by the roll. The liquid is discharged to the outside of the roll. Therefore, since the liquid portion is saturated with liquid, the liquid is discharged to the outside of the roll together with the compressed fluid, so that the space for absorbing the liquid sucked up by the suction / discharge function is secured again. Since the state is eliminated and the suction / exhaust function is maintained, the roll can reliably remove, squeeze and clean the liquid adhering to the surface to be cleaned over a long period of time. In addition, as a timing which injects a compressed fluid, the time of non-operation of a roll is good.

  In addition, high viscosity components in the liquid and / or foreign matter such as iron powder, aluminum powder, etc. mixed in the liquid adhere to the surface of the roll, and the surface of the roll Even when clogging occurs and the intake / exhaust function is hindered, the high-viscosity components and / or iron powder and aluminum adhering to the surface of the roll part together with the compressed fluid and liquid discharged from the inside of the roll part Metal powder such as powder and foreign matters such as dust are also removed from the surface portion of the roll portion. That is, the high-viscosity component dissolves in the liquid discharged from the roll portion and is washed away, and foreign matters such as metal powder and dust are removed by the pressure ejected by the compressed fluid. For this reason, the roll can exhibit the function of sucking and discharging over a long period of time, leading to an improvement in the service life of the roll.

The high-viscosity component in the liquid is, for example, cleaning oil for pressing automobile steel plates, higher fatty acid salts, higher fatty acid esters, petroleum sulfonates, sulfur-based extreme pressure agents, refined mineral oils, refined high-boiling solvents, etc. It is a mixture of Among the above components, higher fatty acid salts and higher fatty acid esters have a kinematic viscosity of about 70 to 100 mm ² / s and correspond to high viscosity components.

  The compressed fluid injected into the hollow portion and the opening may be introduced from a compressor connected to a cylinder that applies pressure such as air pressure or hydraulic pressure to the roll. For this reason, there is no need to newly prepare an external device such as a vacuum pump, which leads to a reduction in capital investment cost and can provide a roll at a low cost.

  The roll of the invention of claim 2 is the roll of claim 1 in particular, and the fluid diffusion groove is formed in the range of the vicinity of one end and the vicinity of the other end in the longitudinal direction of the main body. Therefore, fluid diffusion grooves are not formed at both ends of the main body. Therefore, the compressed fluid does not flow out of the roll from both ends of the main body, and reliably flows out of the roll from the outer periphery of the roll, so there is no loss of the compressed fluid and the liquid from the roll The discharge performance is greatly improved.

  The roll of the invention of claim 3 is the roll of claim 1 or 2 in particular, wherein the fluid diffusion groove is formed substantially parallel to the longitudinal direction of the main body, and the roll is formed from the opening through the hole. Compressed fluid flowing out into the flow part flows into the roll part through the fluid diffusion groove part. Therefore, compared with the case where the fluid diffusion groove portion is not formed on the outer periphery of the main body portion and a pedestal in which only the hole portion is formed is used, the compressed fluid flows uniformly into the roll portion. It leads to the improvement of the discharge performance of the liquid from the roll part. That is, since the compressed fluid uniformly flows into the roll part, the time when the liquid absorbed by the roll part is discharged to the outside of the roll can be shortened, and more uniformly over the entire area of the roll part. The liquid can be discharged, and uneven discharge of the liquid from the roll part can be suppressed.

  The roll of the invention of claim 4 is the roll of claims 1 to 2 in particular, wherein the fluid diffusion groove is formed in an annular shape on the outer periphery of the main body, and from the opening to the roll through the hole. The compressed fluid flowing out flows into the roll part through the fluid diffusion groove part. Therefore, compared with the case where the fluid diffusion groove portion is not formed on the outer periphery of the main body portion and a pedestal in which only the hole portion is formed is used, the compressed fluid flows uniformly into the roll portion. It leads to the improvement of the discharge performance of the liquid from the roll part. That is, since the compressed fluid uniformly flows into the roll part, the time when the liquid absorbed by the roll part is discharged to the outside of the roll can be shortened, and more uniformly over the entire area of the roll part. The liquid can be discharged, and uneven discharge of the liquid from the roll part can be suppressed.

  The roll of the invention of claim 5 is the roll of claims 1 to 2 in particular, wherein the fluid diffusion groove is spirally wound around the outer periphery of the main body, and from the opening to the hole. Then, the compressed fluid flowing out to the roll part flows into the roll part through the fluid diffusion groove part. Therefore, compared with the case where the fluid diffusion groove portion is not formed on the outer periphery of the main body portion and a pedestal in which only the hole portion is formed is used, the compressed fluid flows uniformly into the roll portion. It leads to the improvement of the discharge performance of the liquid from the roll part. That is, since the compressed fluid uniformly flows into the roll part, the time when the liquid absorbed by the roll part is discharged to the outside of the roll can be shortened, and more uniformly over the entire area of the roll part. The liquid can be discharged, and uneven discharge of the liquid from the roll part can be suppressed.

  In the roll of the invention of claim 6, in particular, in the roll of claims 1 to 5, the ratio of the opening area of the fluid diffusion groove portion to the outer periphery of the main body portion is substantially in the center portion than in the vicinity of the end portion of the main body portion. In the vicinity of a substantially central portion of the main body portion, more compressed fluid flows along the fluid diffusion groove portion and flows out of the roll from the outer periphery of the roll portion. By the way, the surface to be cleaned made of a steel plate, non-ferrous metal plate, resin plate, or film has various widths in contact with and passes 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, the discharge performance of the liquid from a roll part improves dramatically by setting it as the form into which more compressed fluid flows into a roll part from the vicinity of the approximate center part of a main-body part.

  According to a seventh aspect of the present invention, there is provided a cleaning device according to any one of the first to sixth aspects, a driving means for rotationally driving the roll, and at least one of the joint portion A or the joint portion B via a pipe. Since a roll that can remove, squeeze, and wash the liquid from the surface to be cleaned is mounted 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.

  The roll of the invention of claim 1 can reliably remove, exploit and wash the liquid adhering to the surface to be cleaned over a long period of time. In addition, the service life of the roll can be improved. Furthermore, a roll can be provided at low cost.

  In the roll according to the second aspect of the invention, the compressed fluid does not flow out of the roll from both ends of the main body, and reliably flows out of the roll from the outer periphery of the roll. Performance is greatly improved.

  The roll of the invention of claim 3 improves the liquid discharging performance from the roll section, so that the time for discharging the liquid from the roll section is shortened and the liquid is more uniformly distributed over the entire roll section. Can be discharged.

  In the roll of the invention of claim 4, since the liquid discharge performance from the roll part is improved, the liquid discharge time from the roll part is shortened, and the liquid is more uniformly distributed over the entire roll part. Can be discharged.

  The roll of the invention of claim 5 improves the liquid discharging performance from the roll section, so that the time for discharging the liquid from the roll section is shortened and the liquid is more uniformly distributed over the entire roll section. Can be discharged.

  In the roll of the invention of claim 6, since more compressed fluid flows into the roll part from the vicinity of the substantially central part of the main body part, the liquid is discharged in the vicinity of the substantially central part of the roll part that absorbs a large amount of liquid. It becomes easy to do, and the discharge performance of the liquid from a roll part improves dramatically.

  Since the cleaning apparatus of the invention of claim 7 exhibits excellent liquid removal performance by the mounted roll, the generation of residue marks in which the liquid remains uneven on the surface to be cleaned is suppressed, and the quality of the surface to be cleaned Can be improved.

  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
FIG. 1 is a front view of a roll in the first embodiment of the present invention, FIG. 2 is a sectional view of the roll in the first embodiment of the present invention, and FIG. 3 is a perspective view of the roll piece as viewed from the front side. 4 (a) is a front view of the pedestal, and FIG. 4 (b) is a front view of the pedestal in another embodiment.

  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, and a main body part 7 having a roll part 2 formed on the outer periphery, and a joint part A8 connected to one end of the main body part 7 is a hollow shape having a hollow part 11. The joint B9 connected to the other end of the main body 7 is solid. 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 4 (a), the main body portion 7 constituting the base 3 has a plurality of fluid diffusion groove portions 13 formed on the outer periphery so as to be substantially parallel to the longitudinal direction. The fluid diffusion groove portions 13 are provided at six locations on the outer periphery of the main body portion 7, and 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 diffusion groove 13 is provided with a plurality of circular holes 14. 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. Further, the joint portion A8 is provided with a hollow portion 11, and at one end thereof, a screw portion 12 to which a rotary joint (not shown) is connected is formed, and the other is a portion of the main body portion 7. One end is connected via a welded joint 20. Therefore, the opening part 10 which the main-body part 7 has, and the hollow part 11 which the joint part A8 has inevitably communicate. One end portion of the solid joint portion B9 is also connected to the other end portion of the main body portion 7 through a joint portion 20 by welding, so that the base 3 is configured. The stopper 5 is fitted and inserted into the recess 19 formed in 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 portion 7 by attaching a convex key to the concave key portion and fitting and inserting the concave groove portion into the convex key.

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

  First, a substantially cylindrical main body portion 7 having a hole 14 and a fluid diffusion groove portion 13 formed on the outer periphery and having an opening 10 is prepared. Next, the hollow joint portion A8 having the hollow portion 11 and the solid joint portion B9 are inserted into both end portions of the main body portion 7 and press-fitted or shrink-fitted, and via the joint portion 20 by welding. The main body portion 7, the joint portion A8, and the joint portion B9 are integrated 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.

  In addition to forming the plurality of generally annular roll pieces 4 on the outer periphery of the main body portion 7 constituting the pedestal 3, the roll portion 2 is configured by forming a flat nonwoven fabric 15 on the outer periphery of the main body portion 7. It can also be formed by wrapping around.

  The diameter of the hole 14 and the width and depth of the fluid diffusion 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 diffusion groove 13 is 2 to 30 mm. The depth and the depth are preferably set to about 0.1 to 5 mm, and the width of the fluid diffusion 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 compressed fluid to the roll part 2, and when the diameter exceeds 8 mm, the diameter is too large to eject the compressed fluid per hole. The power to do is weakened. Further, when the width of the fluid diffusion groove 13 is less than 2 mm, the compressed fluid cannot flow efficiently because the width is too narrow, and when it exceeds 30 mm, it is too wide to form the fluid diffusion groove 13. When the depth of the fluid diffusion groove 13 is less than 0.1 mm, the compressed fluid cannot flow efficiently because it is too shallow, and when it exceeds 5 mm, it takes too much time to form the fluid diffusion groove 13 due to being too deep.

  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, so that the nonwoven fabric 15 and a flat plate made of porous polyurethane having extremely fine bubbles are 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. A hollow portion 11 is formed in the joint portion A8, the hollow portion 11 communicates with the opening portion 10, a roll portion 2 made of a nonwoven fabric 15 is formed on the outer periphery of the main body portion 7, and a fluid diffusion groove portion 13 is formed. Since the hole 14 communicating with the opening 10 is formed in the fluid diffusion groove 13, the surface to be cleaned to which the liquid adheres comes into contact with the roll 2 and the dam function and the suction / discharge of the roll 1. The function removes the liquid. The roll 1 discharges liquid to the inside of the roll portion 2 and discharges it to the outside by the capillary action of the fibers 16 included in the nonwoven fabric 15 constituting the roll portion 2 by the sucking and discharging function. While repeating the suction / exhaust function, the roll unit 2 is gradually saturated with liquid absorption. In the roll 1, the hollow portion 11 is formed in the joint portion A <b> 8 constituting the base 3, and the opening portion 10 is formed in the main body portion 7, and the hollow portion 10 and the opening portion 11 communicate with each other. When a rotary joint (not shown) is connected to the screw part 12 of the joint part A8, a compressor (not shown) is connected via a pipe (not shown), and the compressed fluid is ejected from the compressor, the compressed fluid passes through the pipe. 2 flows in the order of the hollow portion 11 formed in the joint portion A8 and then the opening portion 10 formed in the main body portion 7. When the opening 10 is filled, the compressed fluid flows into the fluid diffusion groove 13 through a plurality of holes 14 formed on the outer periphery of the main body 7 so as to communicate with the opening 10 as indicated by arrows in FIG. The liquid flows uniformly into the roll unit 2 and is discharged to the outside of the roll 1 together with the liquid absorbed by the roll unit 2. Accordingly, since the liquid 2 is discharged to the outside of the roll 1 together with the compressed fluid, the roll portion 2 that has reached the liquid absorption saturation state again secures a gap for absorbing the liquid sucked up by the suction / discharge function. Since the liquid saturation state is eliminated and the intake / exhaust function is maintained, the roll 1 can reliably remove, squeeze and clean the liquid adhering to the surface to be cleaned over a long period of time. In addition, as a timing which injects a compressed fluid, the time of non-operation of the roll 1 is good.

  A high viscosity component in the liquid and / or metal powder such as iron powder or aluminum powder, foreign matter such as dust adhere to the surface of the roll unit 2, and the surface of the roll unit 2 is Even when clogging occurs and the intake / exhaust function is hindered, the high-viscosity component and / or iron powder adhering to the surface portion of the roll portion 2 together with the compressed fluid and liquid discharged from the inside of the roll portion 2 In addition, foreign substances such as metal powder such as aluminum powder and dust are also removed from the surface portion of the roll portion 2. That is, the high viscosity component dissolves in the liquid discharged from the roll unit 2 and is washed away, and foreign matters such as metal powder and dust are removed by the pressure ejected by the compressed fluid. For this reason, the roll 1 can exhibit a function of sucking and discharging over a long period of time, leading to an improvement in the service life of the roll 1.

  What is necessary is just to introduce | transduce the compressed fluid injected to the hollow part 11 and the opening part 10 from the compressor connected with the cylinder which applies pressure, such as air pressure and hydraulic pressure, to the roll 1. FIG. Therefore, it is not necessary to prepare a new external device such as a vacuum pump, which leads to a reduction in capital investment cost and the roll 1 can be provided at a low cost.

Fluid diffusion groove 13 includes a non-forming region L ₂ in the vicinity of one end in the longitudinal direction of the main body portion 7, a formation region L ₁ is within the range of the non-formation region L ₂ in the vicinity of the other end because it is formed Te, the non-forming region L ₂ in the vicinity of both end portions of the main body portion 7 is not formed fluid diffusion groove 13. Therefore, the compressed fluid does not flow out of the roll 1 from both ends of the main body portion 7 and reliably flows out of the roll 1 from the outer periphery of the roll portion 2. The performance of discharging the liquid from the section 2 is greatly improved.

  Since the fluid diffusion groove portion 13 is formed substantially parallel to the longitudinal direction of the main body portion 7, the compressed fluid flowing out from the opening portion 10 through the hole portion 14 to the roll portion 2 passes through the fluid diffusion groove portion 13 and the roll portion 2. Flow into. Therefore, compared with the case where the pedestal 3 in which only the hole portion 14 is formed without the fluid diffusion groove portion 13 formed on the outer periphery of the main body portion 7, the compressed fluid is uniformly distributed to the roll portion 2. As a result, the discharge performance of the liquid from the roll unit 2 is improved. That is, since the compressed fluid uniformly flows into the roll unit 2, the time when the liquid absorbed by the roll unit 2 is discharged to the outside of the roll 1 can be shortened, and the entire area of the roll unit 2 can be reduced. Thus, liquid can be discharged more uniformly, and uneven discharge of liquid from the roll unit 2 can be suppressed.

  Since the roll part 2 is formed by laminating a plurality of substantially annular roll pieces 4 made of the nonwoven fabric 15 on the outer periphery of the main body part 7, the main body part 7 of the roll piece 4 according to the purpose of use of the roll 1. The hardness of the surface portion of the roll portion 2 can be arbitrarily set by adjusting the number of laminated layers. That is, when the number of stacked roll pieces 4 is increased, the hardness of the surface portion of the roll portion 2 is increased, and when the number of stacked roll pieces 4 is decreased, the hardness of the surface portion of the roll portion 2 is decreased.

  Next, the liquid discharge performance from the roll part 2 of the roll 1 of the present invention was tested in the following manner.

First, a main body portion 7 having a substantially cylindrical opening 10 made of iron having an outer diameter of 50 mm, an inner diameter of 30 mm, and an overall length of 190 mm is prepared, and the outer periphery of the main body portion 7 has a width of 3 mm, a depth of 1.5 mm, The fluid diffusion groove portions 13 having a length of 180 mm are formed in six equally spaced outer circumferences of the main body portion 7 so as to be substantially parallel to the longitudinal direction, and holes 14 having a diameter of 2 mm are opened in the fluid diffusion groove portion 13 at intervals of 30 mm. did. Non-forming region L ₂ of the fluid diffusion groove 13 in the outer periphery of the main body portion 7 is in the range of from both ends by 5 mm, forming regions L ₁ of the fluid diffusion groove 13, non from the full-length 190mm in the longitudinal direction of the body 7 in the range of 180mm excluding the formation region _{L 2.} Next, a hollow joint portion A8 having a hollow portion 11 at one end of the main body portion 7 and a solid joint portion B9 at the other end are inserted, and the joint portion 20 is formed by shrink fitting and welding. The base part 7, the joint part A8, and the joint part B9 are integrated to form a base 3 having a total length of 326 mm.

Next, a plurality of generally annular roll pieces 4 having an outer diameter of 130 mm and an inner diameter of 50 mm were extracted from the nonwoven fabric 15 having an apparent density of 0.45 g / cm ³ . And the hole part 17 which the roll piece 4 has is laminated | stacked on the main-body part 7 which comprises the base 3 comprised as mentioned above, and the side edge part 18 of the roll piece 4 is cut and polished by the thickness of 5mm each. Thus, one roll 1 having a roll portion 2 having an outer diameter of 120 mm, an inner diameter of 50 mm, and a total length of 190 mm was manufactured. In addition, the hardness of the surface part of the roll part 2 was set to 78 degrees.

The roll 1 configured as described above was immersed in cleaning oil Preton R-303P (kinematic viscosity 3.9 mm ² / s) manufactured by Sugimura Chemical Industry for 24 hours, and the roll part 2 was saturated with liquid. About 550 cc of cleaning oil was absorbed by the roll unit 2.

Next, the rotary joint was connected to the screw portion 12 of the joint portion A8, and a pipe arranged from the compressor was connected to the rotary joint, and the compressed fluid was injected toward the hollow portion 11. And the quantity of the cleaning oil discharged | emitted from the roll part 2 to the exterior of the roll 1 was calculated by measuring the weight of the roll 1 after 1 hour. The injection pressure of the compressed fluid from the compressor was 1 kgf / cm ² .

  As a result of the test, when the compressed fluid fills the opening 10, the compressed fluid flows into the roll part 2 through the hole 14 formed on the outer periphery of the main body part 7 and the fluid diffusion groove part 13, and is washed by the roll part 2. The oil was discharged outside the roll 1. The amount of the cleaning oil discharged was about 540 cc, and almost the entire amount of the cleaning oil absorbed by the roll unit 2 was discharged to the outside of the roll 1, and the roll 1 of the present invention was very excellent. It had liquid discharge performance.

  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 diffusion groove portions 13 a and 13 b formed on the outer periphery so as to be substantially parallel to the longitudinal direction of the main body portion 7. The fluid diffusion groove portion 13a 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 of the main body portion 7 in the longitudinal direction. It is formed by intensive formation region L ₃ and. In addition, the fluid diffusion groove portion 13b is provided at six locations on the outer periphery of the main body portion 7 between the adjacent fluid diffusion groove portions 13a, and in the vicinity of both end portions of the entire length in the longitudinal direction of the main body portion 7. 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. Thus, in the intensive formation region L _3, will be fluid diffusion grooves 13a, 13b are formed on the outer periphery equal 12 places of the main body portion 7, the fluid diffusion groove 13a, the ratio of the opening area of the 13b, forming regions thus towards the centralized formation region L ₃ is greater than L _1. A plurality of circular holes 14 are formed in the fluid diffusion 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 areas of the fluid diffusion 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 compressed fluid flows along the fluid diffusion groove portions 13 a and 13 b in the vicinity of the substantially central portion of the main body portion 7 and flows out of the roll 1 from the outer periphery of the roll portion 2. By the way, the surface to be cleaned made of a steel plate, a non-ferrous metal plate, a resin plate, or a film is in contact with and passes 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, the discharge performance of the liquid from the roll part 2 improves drastically by setting it as the form into which more compressed fluid flows into the roll part 2 from the vicinity of the substantially center part of the main-body part 7. FIG.

Note that in order to discharge effectively liquid from a substantially central portion in the longitudinal direction of the roll portion 2 serves to increase the thickness in the intensive formation region L ₃ of the main body 7, by reducing the thickness of the roll 2 The distance at which the liquid is discharged may be shortened. Moreover, the roll piece 4 laminated | stacked on the approximate center part in the longitudinal direction of the roll part 2 uses the nonwoven fabric 15 with small apparent density, and ensures the flow path of a liquid widely, and is the method of discharging | emitting a liquid efficiently. There is also.

In FIG. 5A, the main body 27 constituting the pedestal 23 has a plurality of annular fluid diffusion grooves 33 formed on the outer periphery. The fluid diffusion 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. In addition, a plurality of circular holes 34 are formed in the fluid diffusion 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. Further, the joint portion A28 is provided with a hollow portion 11, and at one end portion thereof, is formed a screw portion 12 to which a rotary joint (not shown) is connected, and the other is the main body portion 27. One end is connected via a joint 40 by welding. Therefore, the opening 10 included in the main body 27 and the hollow portion 11 included in the joint A28 inevitably communicate with each other. The joint portion B29 has a solid shape, and one end portion is connected to the other end portion of the main body portion 27 via a joining portion 40 by welding to constitute a base 23. The stopper 5 is fitted and inserted into the recess 39 formed in the joint A28 and the joint B29.

Fluid diffusion groove 33 includes a non-forming region L ₅ in the vicinity of one end in the longitudinal direction of the main body 27, the forming region L ₄ ranges between a non-formation region L ₅ in the vicinity of the other end because it is formed Te, the non-forming region L ₅ in the vicinity of both end portions of the main body portion 27 is not formed fluid diffusion groove 33. Therefore, the compressed fluid does not flow out from both ends of the main body 27 to the outside of the roll 1 and surely flows out of the roll 1 from the outer periphery of the roll 2, so there is no loss of the compressed fluid and the roll The performance of discharging the liquid from the section 2 is greatly improved.

  Since the fluid diffusion groove portion 33 is formed in an annular shape on the outer periphery of the main body portion 27, the compressed fluid flowing out from the opening portion 10 through the hole portion 34 to the roll portion 2 passes through the fluid diffusion groove portion 33 to the roll portion 2. Flows in. Therefore, compared with the case where the base 23 in which the fluid diffusion groove 33 is not formed on the outer periphery of the main body 27 and only the hole 34 is formed is used, the compressed fluid is uniformly distributed to the roll 2. As a result, the discharge performance of the liquid from the roll unit 2 is improved. That is, since the compressed fluid uniformly flows into the roll unit 2, the time when the liquid absorbed by the roll unit 2 is discharged to the outside of the roll 1 can be shortened, and the entire area of the roll unit 2 can be reduced. Thus, liquid can be discharged more uniformly, and uneven discharge of 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 pedestal 23 a has a plurality of annular fluid diffusion groove portions 33 a and 33 b formed on the outer periphery of the main body portion 27. Fluid diffusion grooves 33a, among the full-length over the longitudinal direction of the main body portion 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 diffusion 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 of the main body 7 in the longitudinal direction. Three are formed at ₆ . Thus, fluid diffusion 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 diffusion 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 areas of the fluid diffusion groove portions 33 a and 33 b to the outer periphery of the main body portion 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 portion of the main body portion 27. Since it is large, more compressed fluid flows along the fluid diffusion groove portion 33 b in the vicinity of the substantially central portion of the main body portion 27 and flows out of the roll 1 from the outer periphery of the roll portion 2. By the way, the surface to be cleaned made of a steel plate, a non-ferrous metal plate, a resin plate, or a film is in contact with and passes 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, the discharge performance of the liquid from the roll part 2 improves drastically by setting it as the form into which more compressed fluid flows into the roll part 2 from the vicinity of the approximate center part of the main-body part 27. FIG.

(Example 3)
FIG. 6 is a cross-sectional view of a roll in a third embodiment of the present invention, and FIG. 7 is a front view of a pedestal. 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.

In FIG. 7, the main body 47 constituting the pedestal 43 is formed by spirally winding two fluid diffusion groove portions 53 having different inclination directions on the outer periphery, and the two fluid diffusion groove portions 53. A plurality of circular holes 54 are provided at the intersections in a zigzag pattern. If the compressed fluid is delivered, the setting position of the hole 54 is not limited to the intersection of the two fluid diffusion grooves 53 but can be provided at any position of the fluid diffusion groove 53. Besides the circular shape, the shape 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. The hole 54 communicates with the opening 50 of the main body 47 as shown in FIG. The fluid diffusion 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. Further, 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 the base 3 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 the joint portion A48 connected to the main body portion 47 and the joint portion B49 have the hollow portion 51, and the compressed fluid is supplied from the compressor through the pipe to the joint portion A48 as shown by an arrow in FIG. , And the joint portion B49 can be delivered toward the opening 50 of the main body portion 47. Therefore, the compressed fluid quickly flows into the opening 50 formed in the main body 47, and the compressed fluid flows into the fluid diffusion groove 53 through the hole 54 as shown by the arrow in FIG. From this, the time during which the liquid is discharged to the outside of the roll 41 is significantly reduced.

Fluid diffusion groove 53 includes a non-forming region L ₈ in the vicinity of one end in the longitudinal direction of the main body portion 47, the formation region L ₇ ranges between a non-formation region L ₈ in the vicinity of the other end because it is formed Te, the non-forming region L ₈ in the vicinity of both end portions of the main body portion 47 is not formed fluid diffusion groove 53. Therefore, the compressed fluid does not flow out from the both ends of the main body 47 to the outside of the roll 41, and reliably flows out of the roll 41 from the outer periphery of the roll portion 42. The performance of discharging the liquid from the portion 42 is greatly improved.

  Since the fluid diffusion groove portion 53 is formed by being spirally wound around the outer periphery of the main body portion 47, the compressed fluid flowing out from the opening portion 50 through the hole portion 54 to the roll portion 42 passes through the fluid diffusion groove portion 53. It flows into the roll part 42. Therefore, compared with the case where the base 43 in which the fluid diffusion groove 53 is not formed on the outer periphery of the main body 47 and only the hole 54 is formed, the compressed fluid is uniformly distributed to the roll 42. As a result, the discharge performance of the liquid from the roll part 42 is improved. That is, since the compressed fluid uniformly flows into the roll part 42, the liquid can be discharged more uniformly over the entire area of the roll part 42, and uneven discharge of the liquid from the roll part 42 can be suppressed. it can.

Example 4
FIG. 8 is an explanatory view of a cleaning apparatus equipped with the roll of the present invention. 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 not shown in particular, but are installed in a pair of upper and lower parts on the box-shaped cleaning device 60, and the compressed fluid flows from the compressor 67 through the pipe 65 to both ends of the pedestal 63 of the roll 61a located at the upper part, that is, It is sent to a cylinder (not shown) installed in the joint part A68 and the joint part B69, a certain pressure is applied, and it is rotationally driven in the direction of the arrow by the driving means 64, and the upper roll 61a and the lower roll 61b. In between, the steel plate 70 with oil on both sides is fed in the direction of the white arrow. The compressed fluid is set to be delivered to the cylinder when the rolls 61a and 61b are in operation. The rolls 61a and 61b have a roll portion 62 formed on the outer periphery of the pedestal 63, and are the same as the roll 1 in the first or second embodiment. A rotary joint 66 is connected to the joint portion A68, and a pipe 65 extending from the compressor 67 is connected thereto. In this embodiment, the rotary joint 66 and the pipe 65 are connected only to the joint portion A68 side. However, like the roll 41 shown in the third embodiment, the joint portion A48 and the joint portion are shown. In the form in which the compressed fluid can be ejected from both B49, the rotary joint 66 and the pipe 65 may be connected to both the joint portion A68 and the joint portion B69. The upper roll 61 a removes oil (not shown) from the surface of the steel plate 70, and the lower roll 61 b removes oil from the rear surface of the steel plate 70. The steel plate 70 to which the oil component is attached comes into contact with the roll portion 62, and the oil component is sucked up by the roll portion 62 and discharged into the gap portion of the roll portion 62 due to the capillary action of the fibers 16 included in the nonwoven fabric 15 constituting the roll portion 62. Is done. While the operation as described above is repeated, the sucking and discharging function of the roll unit 62 is lowered, and oil is gradually accumulated in the inside thereof, approaching the liquid absorption saturation state, and the oil removing performance is lowered.

  If the oil removal performance from the steel plate 70 of the roll part 62 is reduced, the cock (not shown) provided in the middle of the pipe 65 is used for the compressed fluid delivery path when the rolls 61a and 61b are resting. Then, as shown in FIG. 2, the compressed fluid is injected from the compressor 67 through the pipe 65 toward the hollow portion 11 as shown by an arrow and sent out. When the compressed fluid fills the opening 10, the compressed fluid flows out to the roll unit 62 through the hole 14 formed on the outer periphery of the main body 7 and the fluid diffusion groove 13. And the oil component absorbed by the roll part 62 is discharged | emitted with the compressed fluid to the exterior of the rolls 61a and 61b. Accordingly, the roll portion 62 made of the nonwoven fabric 15 secures again a gap portion that absorbs the oil sucked up by the sucking and discharging function of the rolls 61a and 61b, so that the liquid absorption saturation state of the roll portion 62 is eliminated, and the roll 61a, 61b can reliably remove 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.

  The cleaning device 60 includes rolls 61a and 61b, drive means 64 that rotationally drives the rolls 61a and 61b, and a compressor 67 that is communicated with the joint portion A68 via a pipe 65. Since the rolls 61a and 61b capable of removing oil from the 70 are installed, excellent liquid 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 excellent in addition to the purpose of removing, squeezing, and cleaning liquids such as 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. As a roll requiring durability, it can be used widely and suitably.
