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).
Japanese Patent Application Laid-Open No. 61-262586 JP-A-7-120145 Japanese Patent No. 3224461

  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 a hole communicating with the opening portion is provided on an outer periphery of the main body portion. The roll part is formed, and the roll part is formed by laminating a plurality of substantially annular roll pieces made of nonwoven fabric, and the roll piece provided with a notch part on the inner periphery. Having the notch A plurality of fluid diffusion groove portions are formed by being continuous in the longitudinal direction of the body portion, and the fluid diffusion groove portion is located on the roll portion side of the hole portion. Then, the liquid is removed by the dam function and the suction / discharge function of the roll. 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, the roll has a notched portion provided on the inner periphery of the roll piece, and a plurality of fluid diffusion groove portions are formed by connecting the cutout portions in the longitudinal direction of the main body portion, and the roll portion of the hole portion formed on the outer periphery of the main body portion. Since the fluid diffusion groove is positioned on the side, the compressed fluid flowing out from the opening to the roll through the hole flows into the roll through the fluid diffusion groove. Therefore, compared with the form in which the fluid diffusion groove is not formed and the hole is formed so as to be substantially in contact with the inner periphery of the roll piece, the compressed fluid flows uniformly into the roll. Leading to improved emission performance. 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.

  Furthermore, foreign matter such as high-viscosity components in the liquid and / or iron powder, aluminum powder, etc. mixed in the liquid and dust 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.

  Furthermore, since the roll part is formed by laminating a plurality of substantially annular roll pieces made of nonwoven fabric on the outer periphery of the main body part, the number of laminations on the main body part of the roll piece is determined according to the purpose of use of the roll. By adjusting, the hardness of the surface part of the roll part can be arbitrarily set. That is, when the number of roll pieces is increased, the hardness of the surface portion of the roll portion is increased, and when the number of roll pieces is decreased, the hardness of the surface portion of the roll portion is decreased. 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 roll of the invention of claim 2 is the roll of claim 1 in particular, wherein the fluid diffusion groove is formed in a range between the vicinity of one end and the vicinity of the other end in the longitudinal direction of the roll. 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 claims 1 to 2, in particular, the roll part has a reinforcing member having a rotating outer diameter smaller than that of the roll piece, and the surface part of the roll part is a core part. Compared to the above, the hardness is low and the flexibility is high, so the elasticity of the roll is improved, the contact area between the roll part and the surface to be cleaned is expanded, and the liquid is efficiently removed from the surface to be cleaned, exploited and cleaned. The On the other hand, since the roll piece and the reinforcing member are laminated, the core part of the roll part is harder than the surface part, and the roll piece is displaced from the main body part during rotation of the roll, and the surface part of the roll part It is possible to prevent unevenness from occurring on the surface. Therefore, the roll does not generate a residue mark on the surface to be cleaned, and the liquid adhering to the surface to be cleaned can be reliably removed, exploited, and washed, and high durability can be maintained.

  The roll of the invention of claim 4 is the roll of claim 3 in particular, in which a notch portion is formed on the inner periphery of the reinforcing member, and the roll portion is continuous even if the reinforcing member is laminated. Since the formed fluid diffusion groove is ensured, the flow of the compressed fluid is not blocked by the reinforcing member. Therefore, the compressed fluid and the liquid can be discharged uniformly from the outer periphery of the roll portion.

  The roll of the invention of claim 5 is the roll of claims 1 to 4, in particular, the notch portion of the roll piece and the reinforcing member is formed at equally spaced locations on the inner periphery, and the roll has a good balance. Rotational blurring does not occur and stable rotation is maintained, so that excellent liquid removal performance is exhibited over a long period of time.

  In the roll of the invention of claim 6, in particular, in the rolls of claims 1 to 5, the ratio of the opening area of the hole to the outer periphery of the main body is larger in the substantially central portion than in the vicinity of the end of the main body. In the vicinity of the 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 according to the first aspect of the present invention can improve the function of discharging the liquid from the roll portion, and can reliably remove, squeeze and clean 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 can reliably remove, squeeze, and wash the liquid adhering to the surface to be cleaned without generating a residue mark on the surface to be cleaned, and maintains high durability. be able to.

  In the roll of the invention of claim 4, the flow of the compressed fluid is not blocked by the reinforcing member, and the compressed fluid and the liquid can be discharged uniformly from the outer periphery of the roll portion.

  The roll of the invention of claim 5 has a good balance, does not generate rotation blur, maintains stable rotation, and can exhibit excellent liquid removal performance over a long period of time.

  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.

A snap ring is used for the fastener 5.

2 and 3, the main body portion 7 constituting the pedestal 3 has a plurality of circular hole portions 13 formed on the outer periphery so as to be substantially parallel to the longitudinal direction. The hole 13 is provided at six locations on the outer periphery 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 in the longitudinal direction of the main body 7. It is established within the range. Further, the hole 13 communicates with the opening 10 of the main body 7. The shape of the hole 13 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 circle. 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 joint 16 by welding. 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 via a joining portion 16 by welding, so that the base 3 is configured. The stopper 5 is fitted and inserted into the recess 15 formed in the joint A8 and the joint B9.

In FIG. 4A, the roll piece 4a is composed of a substantially annular non-woven fabric 17 having a hole 18 in the center and a side edge 19 on the outer periphery. The nonwoven fabric 17 has a plurality of fibers. As shown in FIGS. 2 and 3, the roll piece 4 a is in the vicinity of both end portions in the longitudinal direction of the main body portion 7 constituting the pedestal 3, that is, the non-forming region where the hole portion 13 is not opened on the outer periphery of the main body portion 7. It is laminated in the range of L _2.

In FIG. 4 (b), the roll piece 4b is composed of a substantially annular non-woven fabric 17 having a hole 18 in the center and a side edge 19 on the outer periphery. The nonwoven fabric 17 has a plurality of fibers. Further, the roll piece 4b is formed with approximately U-shaped cutout portions 20 at six equally spaced inner circumferences. Roll pieces 4b is as shown in FIG. 2, and 3, forming regions hole 13 is opened on the outer periphery except for the non-formation region L ₂ in the vicinity of both ends across the longitudinal direction of the main body portion 7 that constitute the base 3 It is laminated in the range of L _1. Then, the notch portion 20 extends over the formation region L ₁ of the main body portion 7, thereby forming a plurality of fluid diffusion groove portions 14 as shown in FIG. 2 and fluid diffusion toward the roll portion 2 side of the hole portion 13. It is set so that the groove part 14 is located. That is, the hole 13 and the fluid diffusion groove 14 are formed to face each other. The number of notches 20 formed on the inner periphery of the roll piece 4 b is changed according to the number of holes 13 formed on the outer periphery of the main body 7 on the circumference. Furthermore, the shape of the notch 20 may be an approximate V shape, an approximate concave shape, or the like other than the approximate U shape.

  In addition, the roll part 2 is formed from the roll pieces 4a and 4b of the total number used for the roll 1. FIG. The roll piece 4a and the roll piece 4b are the nonwoven fabric 17 of the same material, and the outer diameter and the inner diameter are substantially the same. Although not shown in particular, in order to prevent the positional deviation of the roll pieces 4a and 4b with respect to the pedestal 3, a concave groove is formed on the inner periphery of the roll pieces 4a and 4b, and the main body portion 7 constituting the pedestal 3 is formed. The roll pieces 4 a and 4 b may be stacked on the outer periphery of the main body portion 7 by attaching a convex key to the outer periphery in the longitudinal direction 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 7 having a hole 13 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 16 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 17 having a plurality of fibers is prepared, and the non-woven fabric 17 is made of a Thomson type or a laser cutter or the like, and a generally annular roll piece 4a having a hole 18 and a side edge 19 is provided. Then, it is punched into a generally annular roll piece 4b having notches 20 at six portions of the hole 18, the side edge 19, and the inner periphery. Next, a plurality of roll pieces 4 a are overlapped so that the hole 18 penetrates the base 3 and is stacked in the range of the one non-formation region L ₂ where the hole 13 is not formed on the outer periphery of the main body 7. Next, a plurality of roll pieces 4 b are overlapped so that the hole 18 penetrates the pedestal 3 and is stacked in the range of the formation region L ₁ in which the hole 13 is formed on the outer periphery of the main body 7. At that time, the cutout portions 20 are stacked so as to be continuous in the longitudinal direction, and the fluid diffusion groove portion 14 formed by the continuous cutout portions 20 and the hole portion 13 are opposed to each other. Next, a plurality of roll pieces 4 a are overlapped so that the hole 18 penetrates the base 3 and is stacked in the other non-formation region L ₂ where the hole 13 is not formed on the outer periphery of the main body 7. And after compressing only the predetermined length with the press machine from the longitudinal direction of the base 3, the several roll pieces 4a and 4b are pinched | interposed and fixed with the fastener 5 and the plate 6. FIG. Next, by leaving it for a predetermined time, the internal stress of the plurality of roll pieces 4 a and 4 b overlapped is made uniform, the side edge 19 is cut and polished, and the outer periphery of the main body 7 constituting the base 3 A roll 1 is formed by forming a roll 2.

  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 13 and the width and depth of the fluid diffusion groove 14 are not particularly limited. For example, the diameter of the hole 13 is about 1 to 8 mm, and the width of the fluid diffusion groove 14 is 2 to 30 mm. The depth and the depth are desirably set to about 0.1 to 20 mm, and the width of the fluid diffusion groove 14 needs to be set larger than the diameter of the hole 13. When the diameter of the hole 13 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. In addition, when the width of the fluid diffusion groove 14 is less than 2 mm, the compressed fluid cannot flow efficiently because the width is too narrow, and when the width exceeds 30 mm, the width is too wide between the inner periphery of the roll piece 4 b and the main body 7. As the roll 1 rotates, the roll piece 4b is likely to be displaced. When the depth of the fluid diffusion groove portion 14 is less than 0.1 mm, the compressed fluid cannot flow efficiently because it is too shallow. When the depth exceeds 20 mm, the thickness of the roll piece 4 b becomes too thin and the roll 1 The elasticity will be inferior.

  Next, several methods for manufacturing the nonwoven fabric 17 constituting the roll pieces 4a and 4b will be described.

  In the first method, a plurality of fibers 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 non-woven fabric 17 is obtained. The above manufacturing method is generally called needle punching. The cloth-like body is called a web. The obtained nonwoven fabric 17 is impregnated in a polyurethane solution, and the nonwoven fabric 17 is filled with polyurethane. Next, the nonwoven fabric 17 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 17 and a plate made of porous polyurethane having extremely fine bubbles are formed. Form a double structure. As the fibers forming the nonwoven fabric 17, 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 are accumulated in a flat plate shape to form a web that becomes a cloth-like body, and a nonwoven fabric 17 entangled three-dimensionally by needle punching is obtained. The obtained non-woven fabric 17 is bonded with a polymer elastic body containing a crosslinking agent using a method such as spraying, dipping, or impregnation, and is heated to bond the fibers forming the non-woven fabric 17. The nonwoven fabric 17 obtained by this manufacturing method is generally called a chemical bond method nonwoven fabric. In addition, as a fiber which forms the nonwoven fabric 17, natural fibers, such as cotton, rayon, and cellulose, and synthetic fibers, such as polyester, nylon, and acryl, 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 involves melt spinning a synthetic resin such as a polyamide resin, a polyester resin, a polyethylene resin, or a polypropylene resin and injecting a high-pressure water stream of about 100 to 150 kgf to the obtained synthetic fiber to entangle the fibers. Let Next, the non-woven fabric 17 obtained by the above-described production method is formed by adhering a polymer elastic body containing a cross-linking agent to the fibers using a method such as spraying, dipping, or impregnation, and heating to form the non-woven fabric 17. Is generally referred to as hydroentangled nonwoven fabric.

  The manufacturing method of the nonwoven fabric 17 shown above is a representative example. In addition to the above, for example, a hot melted synthetic resin is continuously spun to form fibers, and the fibers are stretched on the collection net. Spunbond method in which fibers are combined to form a nonwoven fabric 17 by pressurizing with a hot roll, and when hot melted synthetic resin is discharged from the spinneret, it is spun with high-temperature air and heated on a collection net A melt blown method in which the formed fibers are bonded to form a nonwoven fabric 17; a synthetic resin is dissolved in a low-boiling solvent such as methylene chloride and chlorofluorocarbon; and the fiber is spun in a heated and pressurized state at the same time as the low boiling point. The flash spinning method in which the solvent is volatilized, the fibers are accumulated on a collection net, and pressed with a hot roll to bond the fibers to form the nonwoven fabric 17. The one having a higher melting point by melting a plurality of synthetic resins having different melting points Synthetic tree A nonwoven fabric 17 manufactured by a fiber bond method, a thermal bond method, or the like, in which a nonwoven fabric 17 is formed by bonding fibers using a melted synthetic resin having a lower melting point as a binder, is used. I do not care. In addition, when the nonwoven fabric 17 is formed on the roll 1, it is strong against repeated contact of the surface to be cleaned and the fibers are not easily frayed. Compared to the case where other fabrics such as a woven fabric and a knitted fabric are used for the roll 1, This leads to improvement in durability of the roll 1.

  About selection of the nonwoven fabric 17 used for the roll pieces 4a and 4b, it considers use conditions, such as the atmospheric temperature in which the roll 1 is used, the property of the liquid used as removal object, cost, etc., and is determined suitably. is there.

  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, and the hollow portion 11 is communicated with the opening portion 10, and a hole portion 13 communicating with the opening portion 10 is formed on the outer periphery of the main body portion 7, and the roll portion 2 is provided. The roll part 2 includes a plurality of substantially annular roll pieces 4a and 4b made of nonwoven fabric 17 and a roll piece 4b provided with a notch 20 on the inner periphery. Since the plurality of fluid diffusion groove portions 14 are formed by connecting 20 in the longitudinal direction of the main body portion 7 and the fluid diffusion groove portion 14 is located on the roll portion 2 side of the hole portion 13, the surface to be cleaned to which the liquid adheres is the roll When it comes into contact with the part 2, the dam function of the roll 1 and the sucker Accordingly, 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 of the nonwoven fabric 17 constituting the roll part 2 by the suction / discharge 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 11 and the opening portion 10 communicate with each other. When a compressor (not shown) is connected to the joint A8 via a pipe (not shown) and the compressed fluid is ejected from the compressor, the compressed fluid passes through the pipe to the joint A8 as shown by the arrow in FIG. It flows in the order of the formed hollow portion 11 and then the opening portion 10 formed in the main body portion 7. When the compressed fluid fills the opening 10, the fluid flows into the fluid diffusion groove 14 through the hole 13 formed on the outer periphery of the main body 7 so as to communicate with the opening 10 as shown by the arrow in FIG. The liquid flows out 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.

  In the roll 1, a plurality of fluid diffusion groove portions 14 are formed by a notch portion 20 provided in the inner periphery of the roll piece 4 b being continuous in the longitudinal direction of the main body portion 7, and holes formed in the outer periphery of the main body portion 7. Since the fluid diffusion groove portion 14 is formed on the roll portion 2 side of the portion 13, the compressed fluid flowing out from the opening portion 10 through the hole portion 13 to the roll portion 2 passes through the fluid diffusion groove portion 14 and the roll portion 2. Flow into. Therefore, since the fluid diffusion groove portion 14 is not formed, and the compressed fluid flows uniformly into the roll portion 2 as compared with the form in which the hole portion 13 is formed so as to be substantially in contact with the inner periphery of the roll piece 4a. It leads to the improvement of the discharge performance of the liquid from the part 2. 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. The liquid can be discharged more uniformly.

  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.

  Since the roll portion 2 is formed by laminating a plurality of substantially annular roll pieces 4 a and 4 b made of the nonwoven fabric 17 on the outer periphery of the main body portion 7, the roll pieces 4 a and 4 b are formed 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 on the main body portion 7. That is, when the number of stacked roll pieces 4a and 4b is increased, the hardness of the surface portion of the roll portion 2 is increased, and when the number of stacked roll pieces 4a and 4b is decreased, the hardness of the surface portion of the roll portion 2 is decreased. 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.

Fluid diffusion groove 14 includes a non-forming region L ₂ in the vicinity of one end in the longitudinal direction of the roll 2, at formation region L ₁ in the range of the non-formation region L ₂ in the vicinity of the other end Since it is formed, the fluid diffusion groove 14 is not formed at both ends of the main body 7. 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.

  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 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 hole 13 having a diameter of 2 mm is divided into the outer circumference of the main body 7. It was opened at intervals of 30 mm so as to be approximately parallel to the outer periphery of the six locations and in the longitudinal direction. Non-forming region L ₂ of the holes 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 hole 13, the non-forming region from the full-length 190mm in the longitudinal direction of the body 7 in the range of 180mm excluding the L _2. Next, a hollow joint portion A8 having a hollow portion 11 at one end of the body portion 7 and a solid joint portion B9 at the other end are inserted, and the joint portion 16 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 4a and 4b having an outer diameter of 130 mm and an inner diameter of 50 mm were extracted from the nonwoven fabric 17 having an apparent density of 0.45 g / cm ³ . Then, the roll pieces 4a, the roll piece 4b having the non-formation region L _2, approximate U-shaped notch 20 on the inner periphery of equally six of the holes 13, the formation region L ₁ of the hole 13 The holes 18 were stacked by passing through the base 3. When to stack rolled piece 4b in the formation region L _1, notch 20 is laminated so as to be continuous in the longitudinal direction, the fluid diffusion groove 14 which is formed by the cutout portion 20 is continuous, the hole 13 is opposed Was set as follows. The fluid diffusion groove 14 had a width of 7 mm and a depth of 3.5 mm. Next, the side edges 19 of the roll pieces 4a and 4b are cut and polished by a thickness of 5 mm each, and a roll 1 having a roll part 2 having an outer diameter of 120 mm, an inner diameter of 50 mm, and a total length of 190 mm is 1 Made this book. 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 13 formed on the outer periphery of the main body part 7 and the fluid diffusion groove part 14, 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.

The

  In FIG.6 (c), the reinforcement member 39a is formed in the substantially annular | circular shape which has the hole 38 in the center part. As shown in FIG. 5, the reinforcing member 39 a is in the vicinity of both end portions in the longitudinal direction of the main body 27 constituting the pedestal 23, that is, in the range of the non-forming region where the hole 33 is not opened on the outer periphery of the main body 27.

Laminated together with the piece 24b. The outer diameter of the reinforcing member 39b is smaller than the outer diameter of the roll piece 24b, and the inner diameter is substantially the same as the inner diameter of the roll piece 24b.

  A plurality of fluid diffusion groove portions 34 are formed as shown in FIG. 5 by the cutout portion 40 of the roll piece 24b and the reinforcing member 39b extending over the formation region of the main body portion 27, and the roll portion of the hole portion 33 is formed. The fluid diffusion groove 34 is set on the 22 side. That is, the hole 33 and the fluid diffusion groove 34 are formed to face each other.

  The reinforcing members 39a and 39b have a smaller rotation outer diameter than the roll pieces 24a and 24b, and the material, shape, and the like are not particularly limited as long as the reinforcing members 39a and 39b do not deteriorate due to swelling or the like by the liquid absorbed by the roll portion 22. As the material of the reinforcing members 39a and 39b, for example, a flat nonwoven fabric 37, a fabric such as a woven fabric or a knitted fabric, a synthetic resin plate, a metal plate, a film-like resin composition, a synthetic resin foam, or the like is used. Preferably, the nonwoven fabric 37 which has the space | gap part which a liquid permeate | transmits easily is used. The porosity of the nonwoven fabric 37 is preferably 5% or more and 50% or less in consideration of strength and the like. The reinforcing member 39a and the reinforcing member 39b may be made of the same material or different materials. Further, the roll pieces 24a, 24b and the reinforcing members 39a, 39b may be made of the same material or different materials. When the roll pieces 24a, 24b and the reinforcing members 39a, 39b are made of different materials, the cost of the roll 21 can be suppressed if the reinforcing members 39a, 39b are made of a material that is less expensive than the roll pieces 24a, 24b. .

  The number of inserted reinforcing members 39a with respect to the roll piece 24a and the number of inserted reinforcing members 39b with respect to the roll piece 24b may be appropriately determined in consideration of the hardness, cost, etc. of the surface portion and core portion of the roll portion 22. For example, one reinforcing member 39a, 39b is inserted into two to ten roll pieces 24a, 24b.

  The operation and action of the roll 21 configured as described above are as follows.

  The roll 21 has a hollow shape in which both the joint portion A28 connected to the main body portion 27 and the joint portion B29 have a hollow portion 31, and the compressed fluid is supplied from the compressor through a pipe to the joint portion A28 as shown by an arrow in FIG. , And the joint portion B29 can be delivered toward the opening 30 of the main body 27. Therefore, the compressed fluid quickly flows into the opening 30 formed in the main body 27, and the compressed fluid flows into the fluid diffusion groove 34 through the hole 33 as shown by the arrow in FIG. From which the liquid is discharged to the outside of the roll 21.

  Since the roll part 22 has reinforcing members 39a and 39b having a smaller rotation outer diameter than the roll pieces 24a and 24b, the surface part of the roll part 22 has lower hardness and higher flexibility than the core part. The elasticity of the roll 21 is improved, the contact area between the roll part 22 and the surface to be cleaned is expanded, and the liquid is efficiently removed from the surface to be cleaned, exploited and cleaned. On the other hand, the roll part 22 has a roll core 24a, 24b and reinforcing members 39a, 39b laminated together, so that the core part of the roll part 22 is harder than the surface part. 27 is prevented from being displaced, and the surface portion of the roll portion 22 is prevented from being uneven. Therefore, the roll 21 does not generate a residue mark on the surface to be cleaned, and can reliably remove, squeeze and clean the liquid adhering to the surface to be cleaned, and can maintain high durability. .

  Since the notch 40 is formed on the inner periphery of the reinforcing member 39b, the roll portion 22 is provided with a continuously formed fluid diffusion groove 34 even if the reinforcing member 39b is laminated. The flow of the compressed fluid is not blocked by the reinforcing member 39b. Therefore, the compressed fluid and the liquid can be uniformly discharged from the outer periphery of the roll unit 22.

  Since the notches 40 included in the roll piece 24b and the reinforcing member 39b are formed at six equally spaced locations on the inner periphery, the roll 21 has a good balance, does not generate rotational shake, and can be rotated stably. Since it is held, excellent liquid removal performance is exhibited over a long period of time.

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 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 the present embodiment, the rotary joint 66 and the pipe 65 are connected only to the joint portion A68. However, like the roll 21 shown in the second or third embodiment, the joint portion A28 is shown. , 48 and the joint portions B29 and 49, 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 of the nonwoven fabric 17 constituting the roll portion 62. The 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 62 through the hole 13 formed on the outer periphery of the main body 7 and the fluid diffusion groove 14. 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 17 secures again a gap for absorbing the oil sucked up by the sucking and discharging functions 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.
