It is a figure explaining the effect | action which sweeps off a foreign material from a steel plate.

(Cleaning device layout)
As shown in FIG. 1, the steel plate SP is conveyed by a conveyor 100. A cleaning device 1 according to an embodiment of the present invention is disposed in the conveyance path of the steel plate SP. The cleaning device 1 removes foreign matters (oil, dust, etc.) adhering to the surface (upper surface US and lower surface LS) of the steel plate SP.

  In FIG. 1, a pair of cleaning devices 1 are arranged on the conveyance path, one cleaning device 1 is arranged on the upper surface US of the steel plate SP, and the other cleaning device 1 is arranged on the lower surface LS of the steel plate SP. ing.

  In FIG. 1, the pair of cleaning devices 1 are arranged at positions facing each other in the vertical direction, but the present invention is not limited to this. Specifically, the pair of cleaning devices 1 can be respectively arranged at different positions in the conveyance direction D of the steel plate SP. Moreover, the cleaning apparatus 1 can be arrange | positioned only to the single side | surface (upper surface US or lower surface LS) of steel plate SP. For example, when foreign matter tends to adhere to the upper surface US of the steel plate SP, the cleaning device 1 can be disposed only on the upper surface US of the steel plate SP to remove foreign matter on the upper surface US.

(Cleaning device structure)
As shown in FIG. 2, the cleaning device 1 includes a brush roll 10 and a suction device 20. First, the structure of the suction device 20 will be described.

(Aspirator structure)
The suction device 20 has a suction pipe 21 for sucking in foreign matters attached to the brush roll 10 (first brush 15 and second brush 16 described later). The suction pipe 21 extends in the direction of the rotation axis RA of the brush roll 10 and is in contact with the brush roll 10 (tips of first brush 15 and second brush 16 described later). As shown in FIG. 3, a suction port 21 a for sucking in foreign matter is formed in a region of the suction pipe 21 that contacts the brush roll 10, and the suction port 21 a extends in the longitudinal direction of the suction pipe 21. ing.

  One end of a duct 22 is connected to the discharge portion 21 b of the suction pipe 21, and the other end of the duct 22 is connected to a suction fan 23. When the suction fan 23 is driven, air is taken in from the suction port 21 a of the suction pipe 21, passes through the duct 22, reaches the suction fan 23, and is discharged from the suction fan 23. Due to this air flow, foreign matter adhering to the brush roll 10 can be removed. Since the air exhausted from the suction fan 23 may include foreign matter that has adhered to the brush roll 10, the foreign matter can be collected by separating the air and the foreign matter.

  In the present embodiment, one suction pipe 21 is provided, but a plurality of suction pipes 21 may be provided. In this case, a plurality of suction pipes 21 can be arranged side by side at positions that do not interfere with the steel plate SP in the circumferential direction of the brush roll 10. The suction port 21a only needs to be able to suck in foreign matter attached to the brush roll 10, and the shape of the suction port 21a can be appropriately determined in consideration of this point.

(Brush roll structure)
Next, the structure of the brush roll 10 is demonstrated using FIG.4 and FIG.5.

  The brush roll 10 has a roll body 11 that rotates around a rotation axis RA. The brush roll 10 is arranged so that the rotation axis RA is substantially orthogonal to the conveyance direction D (see FIG. 1) of the steel plate SP. Shaft portions 11a and 11b supported by bearings (not shown) are provided at both ends of the roll body 11 in the direction of the rotation axis RA. The shaft portion 11b is connected to the motor M via a power transmission mechanism (not shown), and rotates upon receiving power from the motor M. By controlling the driving of the motor M, the rotation speed of the roll body 11 (brush roll 10) can be adjusted.

  As shown in FIG. 5, the roll body 11 has a hollow portion 12. By forming the hollow portion 12 in the roll body 11, the weight of the roll body 11 can be reduced. The roll body 11 does not have to be formed with the hollow portion 12, and the roll body 11 can have a solid structure.

  A first support body 13 and a second support body 14 that protrude outward in the radial direction of the roll body 11 are fixed to the outer peripheral surface of the roll body 11. The first support 13 and the second support 14 are arranged side by side in the direction of the rotation axis RA, and the boundary between the first support 13 and the second support 14 is the roll body 11 in the direction of the rotation axis RA. Is located in the central part C of.

  In the central part C, the end of the first support 13 and the end of the second support 14 are arranged adjacent to each other. The first support 13 is provided in a region located closer to the shaft portion 11a than the central portion C, and the second support 14 is provided in a region located closer to the shaft portion 11b than the central portion C. It has been.

  As can be seen from FIGS. 4 and 5, each of the first support body 13 and the second support body 14 is spirally disposed on the outer peripheral surface of the roll body 11. The direction of the spiral of the first support 13 and the direction of the spiral of the second support 14 are opposite to each other.

  Specifically, when the first support 13 is viewed from the shaft portion 11a, the spiral of the first support 13 extends toward the central portion C while rotating counterclockwise. When the second support 14 is viewed from the shaft portion 11b, the spiral of the second support 14 extends toward the central portion C while rotating clockwise. And in the center part C, the edge part of the 1st support body 13 and the edge part of the 2nd support body 14 are adjacent.

  In the present embodiment, the spiral interval W1 (see FIG. 4) of the first support 13 is made equal, and the spiral interval W2 (see FIG. 4) of the second support 14 is made equal. Note that the spiral interval W1 of the first support 13 and the spiral interval W2 of the second support 14 do not have to be equal, and depending on the position in the direction of the rotation axis RA, the spiral interval W1, W2 may be different.

  The root portion of the first brush 15 is fixed to the tip portion of the first support 13. For example, the first brush 15 can be fixed to the first support 13 by forming a groove at the tip of the first support 13 and inserting the root of the first brush 15 into the groove. . As can be seen from FIGS. 4 and 5, the root portion of the first brush 15 is bundled, and the first brush 15 extends from the root portion toward the tip portion. By widening the tip of the first brush 15, the contact area between the first brush 15 and the steel plate SP is widened, so that it is easy to remove foreign matters attached to the steel plate SP.

  As described above, since the first support 13 is disposed in a spiral shape, the first brush 15 fixed to the first support 13 is also disposed in a spiral shape. The direction of the spiral of the first brush 15 is the same as the direction of the spiral of the first support 13.

  The root portion of the second brush 16 is fixed to the distal end portion of the second support body 14. For example, it is possible to fix the second brush 16 to the second support 14 by forming a groove at the tip of the second support 14 and inserting the root of the second brush 16 into the groove. . As can be seen from FIGS. 4 and 5, the root portion of the second brush 16 is bundled, and the second brush 16 spreads from the root portion toward the tip portion. By widening the tip of the second brush 16, the contact area between the second brush 16 and the steel plate SP is widened, and it becomes easy to remove foreign substances attached to the steel plate SP.

  As described above, since the second support 14 is disposed in a spiral shape, the second brush 16 fixed to the second support 14 is also disposed in a spiral shape. The direction of the spiral of the second brush 16 is the same as the direction of the spiral of the second support 14. As shown in FIGS. 4 and 5, in the central part C, a part of the first brush 15 and a part of the second brush 16 are in contact with each other.

  As materials for the first brush 15 and the second brush 16, known materials can be appropriately employed. For example, the first brush 15 and the second brush 16 can be manufactured using synthetic fibers such as nylon 6,6, polypropylene, and polyester. In addition, if conductive fibers are used as the material of the first brush 15 and the second brush 16, the charging of the first brush 15 and the second brush 16 can be suppressed, and foreign matter is caused by static electricity by the first brush 15 and the second brush 16. Adhering to the brush 16 can be suppressed. Here, if the synthetic fiber and the conductive fiber described above are mixed, the first brush 15 and the second brush 16 are charged by the conductive fiber while suppressing the deformation of the first brush 15 and the second brush 16 by the synthetic fiber. Can be suppressed.

(Brush roll action)
Next, the effect | action of the brush roll 10 is demonstrated using FIG. In FIG. 6, the steel plate SP is transported in a direction orthogonal to the paper surface of FIG. In FIG. 6, for convenience of explanation, the steel plate SP is shown at a position away from the first brush 15 and the second brush 16, but actually, the tip portions of the first brush 15 and the second brush 16 are In contact with the surface of the steel plate SP.

  When the brush roll 10 is rotated around the rotation axis RA, the first brush 15 and the second brush 16 rotate while changing the contact position with the steel plate SP. Here, the foreign matter adhering to the surface of the steel plate SP may adhere to the first brush 15 and the second brush 16. Foreign matter adhering to the first brush 15 and the second brush 16 is sucked by the suction device 20 as described above.

  The rotating first brush 15 can eject foreign matter F adhering to the surface of the steel plate SP toward the upstream side of the conveying path of the steel plate SP. Here, since the first brush 15 is arranged in a spiral shape, the foreign matter F is obliquely ejected by the first brush 15 toward the edge E1 of the steel plate SP. In this way, the foreign matter F moves toward the edge E1 of the steel plate SP while being ejected by the first brush 15, and falls from the edge E1. The edge E1 is one end of the steel plate SP in a direction orthogonal to the conveyance direction D (see FIG. 1) of the steel plate SP.

  The rotating second brush 16 can eject the foreign matter F adhering to the surface of the steel plate SP toward the upstream side of the conveying path of the steel plate SP. Here, since the second brush 16 is arranged in a spiral shape, the foreign matter F is obliquely ejected by the second brush 16 toward the edge E2 side of the steel plate SP. In this way, the foreign matter F moves toward the edge E2 of the steel plate SP while being ejected by the second brush 16, and falls from the edge E2. The edge E2 is the other end of the steel plate SP in a direction orthogonal to the conveyance direction D (see FIG. 1) of the steel plate SP.

  Moreover, since the 1st brush 15 is arrange | positioned helically, the foreign material F adhering to the surface of steel plate SP can be extruded toward the axial part 11a side with the 1st brush 15. FIG. Similarly, since the 2nd brush 16 is arrange | positioned spirally, the foreign material F adhering to the surface of steel plate SP can be extruded toward the axial part 11b side with the 2nd brush 16. FIG. Thereby, the foreign material F moves along the surface of the steel plate SP and falls from the edges E1 and E2 of the steel plate SP.

  As described above, the foreign matter F is attached to the first brush 15 and the second brush 16 and the foreign matter F is sucked by the suction device 20, or the foreign matter F is removed from the edge of the steel plate SP by the first brush 15 and the second brush 16. It can suppress that the foreign material F remains on the surface of steel plate SP by dropping from E1, E2.

  In this embodiment, since the 1st brush 15 and the 2nd brush 16 are arrange | positioned by making the center part C into a boundary, the foreign material F adhering to the surface of steel plate SP is the edge E1 of steel plate SP from the center part C. , Move toward E2. Thereby, the foreign material F adhering to the surface of the steel plate SP can be distributed and moved to the edges E1 and E2 of the steel plate SP, and the foreign material F can be efficiently dropped from the edges E1 and E2 of the steel plate SP. .

  Here, as shown in FIG. 6, it is preferable that the 1st brush 15 is arrange | positioned to the axial part 11a side rather than the edge E1 of steel plate SP. Thereby, when the foreign material F is pushed out by the first brush 15, the foreign material F is easily dropped from the edge E1. Similarly, it is preferable that the 2nd brush 16 is arrange | positioned to the axial part 11b side rather than the edge E2 of steel plate SP. Thereby, when the foreign material F is pushed out by the second brush 16, the foreign material F is easily dropped from the edge E2.

  In the present embodiment, the suction device 20 is provided, but the suction device 20 may be omitted. As described above, even if only the brush roll 10 is used, the foreign matter F adhering to the surface of the steel plate SP can be dropped from the steel plate SP. Here, when the foreign substance F adheres to the 1st brush 15 or the 2nd brush 16, rotation of the brush roll 10 is stopped and the 1st brush 15 or the 2nd brush 16 to which the foreign substance F adhered is cleaned. Can do.

  The brush roll 10 may be fixed at a predetermined position (a position in contact with the surface of the steel plate SP), or may be moved in the vertical direction (that is, the vertical direction in FIG. 1) with respect to the surface of the steel plate SP. it can. When the brush roll 10 is moved in the vertical direction, the shaft portion 11 of the brush roll 10 may be connected to an elevator (not shown). Further, when the suction pipe 21 is disposed, the suction pipe 21 may be moved together with the brush roll 10. In this case, the duct 22 can be formed of a deformable material so that the movement of the suction pipe 21 can be followed.

  As an elevator, it is sufficient that the brush roll 10 can be moved in the vertical direction, and a known mechanism can be appropriately employed. Here, the operator manually operates the elevator to move the brush roll 10 up and down, or the operator operates the elevator actuator to move the brush roll 10 up and down. Can do.

  By moving the brush roll 10 in the vertical direction, the first brush 15 and the second brush 16 are brought into contact with the surface of the steel plate SP, or the first brush 15 and the second brush 16 are separated from the surface of the steel plate SP. Can do. For example, when the joint of two steel plates SP approaches the brush roll 10, the brush roll 10 can be moved to a position away from the steel plate SP. Thereby, it can prevent that the 1st brush 15 or the 2nd brush 16 is caught in the joint of steel plate SP.

  On the other hand, in the state where the first brush 15 and the second brush 16 are in contact with the surface of the steel plate SP, the distance between the brush roll 10 and the steel plate SP is adjusted by moving the brush roll 10 in the vertical direction, thereby The contact pressure of the first brush 15 and the second brush 16 with respect to the surface of the SP can be adjusted. By adjusting the contact pressure in this way, the problems described below can be suppressed, and the foreign matter F can be efficiently removed from the surface of the steel plate SP. If the first brush 15 and the second brush 16 are pressed too much against the surface of the steel plate SP, the first brush 15 and the second brush 16 are easily deformed, or the foreign matter F is removed from the steel plate SP by the first brush 15 and the second brush 16. Or press against the surface. On the other hand, if the contact pressure described above is too low, the first brush 15 and the second brush 16 may make it difficult to move the foreign matter F on the surface of the steel plate SP.
