Summary of the Invention

Problems to be Solved by the Invention

[0005] The roll described in Patent Document 1 above has a mechanism to restore suction or discharge power and delay the deterioration of roll performance when the roll section becomes partially clogged due to the transfer of metal powder and dust adhering to steel plates or the like. Backwashing is the process of sending fluid from the main body to the roll section and discharging the dirt along with the fluid from the outer circumference of the roll section. However, when the roll section is partially clogged, a large amount of fluid is discharged from the unclogging part, while a small amount of fluid is discharged from the clogged part, which presents a problem.

[0006] The present invention aims to solve the aforementioned conventional problems and to provide a roll and cleaning device with a structure that effectively discharges fluids, metal powders, and dust, thereby maintaining the suction or discharge force of the roll. [Means for solving the problem]

[0007] To solve the aforementioned conventional problems, the invention of claim 1 provides a roll for removing, extracting, and washing liquids such as water, oil, or chemical components adhering to a surface to be cleaned, such as a steel plate, non-ferrous metal plate, resin plate, paper, or film, wherein the roll comprises a roll portion and a base, the roll portion is formed by laminating approximately annular roll pieces made of nonwoven fabric on the outer circumference of the base along the longitudinal direction of the base, the base comprises a substantially cylindrical main body portion with a hollow portion formed at the axial center, and joint portions connected to both ends of the main body portion, and the The body portion has a groove portion provided along the axial direction of the outer circumferential surface and having a plurality of suction and discharge holes communicating with the hollow portion, and a substantially plate-shaped opening / closing member positioned to include the inside of the groove portion and to open and close the suction and discharge holes at predetermined locations, the roll portion has a space portion formed above the groove portion along the longitudinal direction of the groove portion, and the opening / closing member is characterized by opening and closing the suction and discharge holes at predetermined locations by moving along the longitudinal or short direction of the groove portion, thereby applying a suction force or discharge force to the roll portion located near the opened suction and discharge hole.

[0008] In the invention of claim 1, the opening and closing member is moved along the longitudinal or transverse direction of the groove to open and close the suction and discharge holes at predetermined locations, and a suction or discharge force is applied to the roll section located near the opened suction and discharge holes. As a result, metal powder and dust that cause clogging can be effectively discharged from the roll section with an appropriate amount of fluid, and the suction or discharge force of the roll section can be maintained (the decrease in discharge force can be delayed).

[0009] The invention of claim 2 is characterized in that, in the invention of claim 1, the groove portion has an opening for an intake / exhaust hole formed on the bottom surface of the groove portion. This allows the opening / closing member to reliably open and close the intake / exhaust hole.

[0010] The invention of claim 3 is characterized in that, in the invention of claim 1 or 2, the groove is formed such that, in a cross section perpendicular to the longitudinal direction of the groove, the width of the opening surface is narrower than the width of the bottom surface. This prevents the opening and closing member from coming off upward from the opening surface side of the groove.

[0011] The invention of claim 4 is characterized in that, in the invention of claim 1, the opening / closing member has a plurality of adjustment holes or adjustment grooves that can communicate with the intake / exhaust holes. This makes it possible to open and close multiple intake / exhaust holes with a single opening / closing member.

[0012] The invention of claim 5 is characterized in that, in the invention of claim 4, the plurality of adjustment holes or adjustment grooves of the opening / closing member are formed such that the opening area on the central side in the longitudinal direction of the opening / closing member is increased, and by moving the opening / closing member, only the suction / discharge holes formed at the longitudinal end of the base can be closed. This makes it possible to effectively supply fluid to the longitudinal central part of the roll section, which is prone to clogging.

[0013] The invention of claim 6 is characterized in that, in the invention of claim 1, the base has opening and closing members on both ends. This increases the degree of freedom in selecting which suction and discharge holes to open and close, and allows dust to be effectively discharged from the roll section.

[0014] The invention of claim 7 is a cleaning device characterized by comprising at least a roll according to any one of claims 1 to 6, a driving means for rotating the roll, and a vacuum pump. This makes it possible to provide a cleaning device equipped with a roll that effectively discharges metal powder and dust that cause clogging from the roll with an appropriate amount of fluid, thereby maintaining the suction or discharge force of the roll. [Effects of the Invention]

[0015] The invention of the roll according to claim 1 and the invention of the cleaning device according to claim 7 allow for the effective discharge of metal powder and dust that cause clogging from the roll section with an appropriate amount of fluid, thereby maintaining the suction or discharge force of the roll section. Furthermore, the invention of claim 2 allows the opening and closing member to reliably open and close the suction and discharge holes.

[0016] The invention of claim 3 can prevent the opening / closing member from coming off upward from the opening surface side of the groove. Furthermore, the invention of claim 4 can open and close multiple intake / exhaust holes with a single opening / closing member.

[0017] Claim 5 allows for effective supply of fluid to the central portion of the roll section in the longitudinal direction, where clogging is likely to occur. Furthermore, the invention of Claim 6 provides greater freedom in selecting which suction and discharge holes to open and close, allowing for effective discharge of metal powder and dust from the roll section.

[0019] Hereinafter, embodiments of the present invention will be described with reference to the drawings. It should be noted that the present invention is not limited by these embodiments. Figure 1 is a perspective view showing the first embodiment of the roll according to the present invention, Figure 2 is a plan view thereof, and Figure 3 is a cross-sectional view thereof. Further, Figure 4 is a partially exploded perspective view showing the first embodiment of the roll according to the present invention. Figure 5(a) is a partial enlarged cross-sectional view showing the first embodiment of the roll according to the present invention, and Figure 5(b) is a perspective view showing the first embodiment of the opening / closing member. The roll of the first embodiment will be described below using these drawings.

[0020] The roll 10 of the first embodiment according to the present invention is a roll for removing, squeezing, and cleaning liquids such as moisture, oil, or chemical components adhering to the surface to be cleaned in the form of a steel plate, non-ferrous metal plate, resin plate, paper product, or film, and has a roll portion 1 and a pedestal 2.

[0021] The roll section 1 is formed by stacking approximately annular roll pieces 1a, 1a, ... made of nonwoven fabric on the outer circumference of the base 2 along the longitudinal direction of the base 2. The base 2 has a substantially cylindrical main body 2a with a hollow section 2c formed at its axial center, and joint sections 2b, 2b connected to both ends of the main body 2a. Note that in the exploded perspective view of Figure 4, multiple roll pieces 1a are omitted, and only one is depicted. Reference numerals 7a and 7b are flanges for fixing multiple roll pieces 1a to the outer circumference of the base 2. Each roll piece 1a has a hole 1c that fits with the outer circumference of the base 2, and semicircular sections 1d, 1d, ... formed at four equally spaced locations on its inner circumference. The space 1b, described later, is formed by stacking multiple roll pieces 1a along the longitudinal direction of the base with their semicircular sections 1d aligned.

[0022] The main body portion 2a has a groove portion 2d that is provided along the axial direction of the outer circumferential surface and has a plurality of intake and exhaust holes 2e, 2e, ... that communicate with the hollow portion 2c, and a substantially plate-shaped opening and closing member 3 that is positioned including the inside of the groove portion 2d and opens and closes the intake and exhaust holes 2e at predetermined locations.

[0023] The roll section 1 is located above the groove section 2d, and a space 1b is formed along the longitudinal direction of the groove section 2d. The opening / closing member 3 is moved along the longitudinal direction of the groove section 2d to open and close the suction / discharge holes 2e at predetermined locations, thereby applying a suction or discharge force to the roll section 1 located near the opened suction / discharge holes 2e.

[0024] The roll 10 of the first embodiment, as described above, is configured such that by moving the opening / closing member 3 along the longitudinal direction of the groove 2d, it opens and closes the suction / discharge holes 2e at predetermined locations, and applies a suction or discharge force to the roll section 1 located near the opened suction / discharge holes 2e. Therefore, with an appropriate amount of fluid, metal powder and dust that cause clogging can be effectively discharged from the roll section 1, and the suction or discharge force of the roll section 1 can be maintained. The type of fluid can be cleaning oil, water, air, etc., but any fluid that can pass through the roll section is included in the present invention.

[0025] The groove 2d has an opening for the intake / exhaust hole 2e formed at its bottom surface 2f. This allows the opening / closing member 3 to reliably open and close the intake / exhaust hole 2e.

[0026] The opening / closing member 3 has a plurality of adjustment holes 3a and 3b that can communicate with the suction / discharge holes 2e. Furthermore, the plurality of adjustment holes 3a and 3b of the opening / closing member 3 are formed so that the opening area on the central side in the longitudinal direction of the opening / closing member 3 is larger (3a > 3b), and the adjustment holes 3a and 3b are arranged so that by moving the opening / closing member 3, only the suction / discharge holes 2e formed at the longitudinal end of the base 2 can be closed. As a result, the opening and closing of multiple suction / discharge holes 2e, 2e... can be performed with a single opening / closing member 3, and cleaning oil can be effectively supplied to the longitudinal central part of the roll section 1 where clogging is likely to occur.

[0027] Although it differs from the configuration of the roll 10 in the first embodiment, the base may be configured to have opening and closing members on both ends (not shown). This increases the degree of freedom in selecting which suction and discharge holes to open and close, and allows for the effective discharge of metal powder and dust from the roll section.

[0028] Figure 5(c) is a perspective view showing a second embodiment of the opening / closing member. The opening / closing member 13 of the second embodiment is a substantially plate-shaped member that opens and closes an intake / exhaust hole 2e at a predetermined location formed in the main body 2a, similar to the opening / closing member 3 of the first embodiment described above, and has a plurality of adjustment grooves 13a, 13b that can communicate with the intake / exhaust hole 2e.

[0029] In the second embodiment, the opening / closing member 13 has multiple adjustment grooves 13a and 13b formed such that the opening area on the longitudinal central side of the opening / closing member 13 is larger (13a > 13b). The adjustment grooves 13a and 13b are arranged so that by moving the opening / closing member, only the suction / discharge holes 2e formed at the longitudinal ends of the base can be closed. This allows the opening and closing of multiple suction / discharge holes 2e, 2e... to be performed by a single opening / closing member 13, and also allows for effective fluid supply to the longitudinal central portion of the roll section 1, where clogging is likely to occur.

[0030] Figure 6(a) is a perspective view showing a second embodiment of the roll according to the present invention, and Figure 6(b) is a perspective view showing an opening / closing member of the third embodiment used in the roll of the second embodiment. The roll of the second embodiment will be described below using these figures.

[0031] The roll 20 of the second embodiment has a main body portion 12a which has a groove portion 12d having a plurality of suction and discharge holes 12e, 12e, ... provided along the axial direction of the outer peripheral surface and communicating with a hollow portion 12c, and a substantially plate-shaped opening and closing member 23 which is arranged inside the groove portion 12d and opens and closes the suction and discharge holes 12e at predetermined locations.

[0032] The opening / closing member 23 is configured to open and close the suction / discharge hole 12e at a predetermined location by moving along the shorter direction of the groove, thereby applying a suction or discharge force to the roll section 11 located near the opened suction / discharge hole 12e.

[0033] In a cross-section perpendicular to the longitudinal direction of the groove 12d, the width B of the opening surface is formed to be narrower than the width A of the bottom surface. This prevents the opening / closing member 23 from coming off upward from the opening surface side of the groove 12d.

[0034] Furthermore, the opening / closing member 23 is formed such that the opening area on the longitudinal central side of the opening / closing member 23 is larger ((23a + 23b) > 23b), and the adjustment holes 23a and 23b are arranged so that by moving the opening / closing member 23, only the suction / discharge holes 12e formed at the longitudinal end of the base can be closed. The other configurations are the same as those of the roll 10 in the first embodiment, so their description is omitted.

[0035] Figure 7 is a perspective view showing the cleaning apparatus according to the present invention in use. The cleaning apparatus 30 comprises a pair of rolls 10a and 10b according to the present invention, a driving means 40 for rotating the rolls 10a and 10b, and a vacuum pump 50.

[0036] Rolls 10a and 10b are installed in a washing device 30 as an upper and lower pair. A constant pressure is applied to both ends of the base 2 of the upper roll 10a, i.e., the rotation support parts 6, and the driving means 40 rotates it in the direction of the arrow. Piece-shaped steel plates 4, with oil (not shown) attached to both sides, are conveyed between the upper roll 10a and the lower roll 10b in the direction of the white arrow. A rotary joint (not shown) is attached to one end of the rotation support part 6 and is connected to a vacuum pump 50 via piping 5. The upper roll 10a removes oil from the surface of the steel plate 4, and the lower roll 10b removes oil from the back surface of the steel plate 4. The oil-covered steel plate 4 comes into contact with the roll part 1, and the oil is drawn up to the roll part 1 by the capillary action of the fibers of the nonwoven fabric that makes up the roll part 1, and also discharged into the space of the roll part 1. Note that rolls 10a and 10b are the same as roll 10 in the first embodiment described above.

[0037] In the state of rolls 10a and 10b as described above, when the vacuum pump 50 is operated to apply a vacuum suction force, negative pressure is applied to the roll section 1, and the oil absorbed by the roll section 1 becomes a fluid. This fluid flows through the space and suction / discharge holes into the hollow section, and is sucked out to the outside of rolls 10a and 10b through the piping 5 from the hollow section (not shown) formed in one of the rotating support sections 6, and discharged. The fluid is then moved again to the cleaning oil tank via a filter (not shown) by the vacuum pump 50 and through piping (not shown). Therefore, the liquid absorption saturation state of the roll section 1 is resolved, and the suction / discharge function is maintained, so rolls 10a and 10b can reliably remove oil adhering to the steel plate 4 over a long period of time.

[0038] Although not shown in the diagram, by replacing the vacuum pump 50 with an injection device connected to the piping 5, the roll section 1 can be backwashed. Fluid is sent from the main body 2a to the roll section 1, and dirt is discharged along with the fluid from the outer circumference of the roll section 1, thereby restoring the blockage of the roll section 1. In this case, the opening / closing member 3 is moved to apply a discharge force to the roll section 1 located near the suction / discharge hole, so that dust that causes clogging is effectively discharged from the roll section 1 with an appropriate amount of fluid, and the suction and discharge force of the roll section 1 can be maintained. [Industrial applicability]

[0039] The roll and cleaning apparatus according to the present invention are used to remove, extract, and clean liquids such as water, oil, or chemical components adhering to a surface to be cleaned, such as steel plates, non-ferrous metal plates, resin plates, paper, or film.
