The following description will be made assuming that the remaining one. The shape of the punched portion 101 of the workpiece 100 shown in FIG. 3 is only an example, and it goes without saying that the shape is actually various depending on the type, size, and the like of the workpiece 100.

  Next, with reference to FIG. 4 thru | or FIG. 8, the structure, arrangement | positioning, modification, etc. of the said 3 steps | paragraphs of elastic rolls 11A, 11B, and 11C are demonstrated.

  FIG. 4 shows the configuration and arrangement of the three-stage elastic rolls 11A, 11B, and 11C. These elastic rolls 11A, 11B, and 11C are each made of elastic material such as urethane foam on the outer periphery of the shaft core 15. The material 16 is wound in a plurality of layers, and is driven to rotate in the direction of the arrow in FIG. 5 by the elastic roll driving unit 64, and remains in the punched portion 101 due to distortion of the outer peripheral portion due to contact between the elastic material 16 and the punched portion 101 of the workpiece 100. The scraps 102 are pressed and removed downward, and a conveying force in the conveying direction is applied to the workpiece 100.

Moreover, the elastic rolls 11A, 11B, and 11C wind the elastic material 16 having a predetermined width on the outer periphery of the shaft core 15, for example, in four or three places, for example, in a divided arrangement.
In the present invention, the elastic material 16 having a predetermined width is wound around the outer periphery of the shaft core 15 in a divided arrangement, and the elastic material 16 is divided into the outer periphery of the shaft core 15 without winding the divided arrangement of the elastic material 16. Of course, it is also possible to wind an elastic material that is not wound. In the present invention, each of the three-stage elastic rolls 11A, 11B, 11C and the receiving roll 13 is wound around the outer periphery of the shaft core, and an elastic material having a predetermined width is wound in, for example, four or three locations in a divided arrangement. Further, the elastic material that is not divided into the outer periphery of each shaft core without winding the elastic material in a divided arrangement on any of the three-stage elastic rolls 11A, 11B, 11C, and the receiving roll 13 Further, an elastic material having a predetermined width is provided on one of the three-stage elastic rolls 11A, 11B, 11C and the receiving roll 13 on the outer periphery of the shaft core, for example, at four locations or three. It is also possible to wind the elastic material that is not divided on the outer periphery of the shaft core without winding the elastic material in a divided arrangement over the other portion and without winding the elastic material in a divided arrangement.
In the present embodiment, the first-stage and third-stage elastic rolls 11A and 11C are divided into four locations having a predetermined gap 17 along the axial direction of the shaft core 15, and the second-stage elastic roll 11B. In FIG. 3, three divisional arrangements having a predetermined gap 17 along the axial direction of the shaft core 15 are employed. And these are arrange | positioned so that the roll part of the division | segmentation arrangement | positioning of the 2nd step | paragraph elastic roll 11B may become the position which complements the clearance gap 17 of the roll arrangement | positioning of the division | segmentation arrangement | positioning in the first stage and the 3rd stage | paragraph elastic rolls 11A and 11C. .

With such an arrangement of the elastic rolls 11A, 11B, and 11C, a blind spot region with respect to the punched portion 101 of the workpiece 100 does not exist.
In the present embodiment, the elastic rolls 11A, 11B, and 11C having a three-stage configuration are employed, but the present invention is not limited to this, and a larger number of stages can be used. Further, the number of axial divisions of the shaft core 15 is not limited to the above case.

FIG. 6 shows a modification of the shape of, for example, the elastic roll 11A (the same applies to the elastic rolls 11B and 11C). The elastic roll 11D shown in FIG. An irregular shape in which the cross-sectional shape in the direction of rotation perpendicular to the axial direction exhibits a substantially circular shape of four leaves, with the string-like body 18 such as a wire narrowed to two crossing locations along the axial direction (rotational axis direction) of the shaft core 15 It is a roll.
That is, with the rotation of the elastic roll 11D, the four rolls having a substantially cylindrical shape are configured to contact the workpiece 100 in order. In addition, the number of narrowing-down locations is not limited to the case described above.

  By appropriately using such an elastic roll 11D, it is possible to change the pressing force when pressing and removing the residue 102 remaining on the punched portion 101 of the workpiece 100 downward, and the workpiece 100 from which the residue 102 is to be removed can be changed. Appropriately responds to changes in type and thickness.

  FIGS. 7 and 8 show other modified examples of the shape of, for example, the elastic roll 11A (the same applies to the elastic rolls 11B and 11C). The elastic roll 11E shown in FIGS. 7 and 8 is the elastic roll 11E. The elastic material 16 is narrowed down at two locations along the rotational direction by a string-like body 18 such as a thread or a wire at a predetermined interval, and at two locations along the rotational direction at the outer peripheral portion and having a predetermined interval. The shape has a recess 19.

  Even when such an elastic roll 11E is used as appropriate, the pressing force for pressing and removing the residue 102 remaining on the punched portion 101 of the workpiece 100 can be changed, and the workpiece 100 from which the residue 102 is to be removed. It is possible to respond appropriately when changing the type and thickness of the plate.

  FIG. 9 shows a state in which the residue 102 is removed by the air nozzle 12A. The high pressure air supplied from the air supply unit 67 is blown to the punched portion 101 of the workpiece 100, and the residue remaining in the punched portion 101 is shown. 102, and fine dust etc. are dropped downward. The air nozzle 12A is preferably arranged with the air discharge end as close to the surface of the workpiece 100 as possible.

  According to such an air nozzle 12A, the flow of high-pressure air indicated by an arrow in FIG. 9 impacts the debris 102 and presses the debris 102 so that the debris 102 remaining in the punched portion 101 is efficiently removed. Including those that cannot be removed by the elastic roll 11A, it can be dropped downward. The other air nozzles 12B to 12D are the same as in the case of the air nozzle 12A described above.

  FIG. 10 is an enlarged view of the elastic roll 31 with protrusions. An elastic material 34 such as a soft rubber material in which a large number of truncated cone-shaped protrusions 33 are provided on the outer periphery of the shaft core 32 is wound. It is comprised and it is rotationally driven by the said elastic roll drive part 65 with a protrusion.

  The protrusion 33 is formed with a diameter d1 of a base end portion on the elastic material 34 side including a soft rubber material having a diameter of, for example, 5 mm and a diameter d2 of a protruding end of about 2 mm, and rotates above the workpiece 100. Then, the protrusion 33 is brought into contact with the upper surface of the residue 102 remaining on the punched portion 101 of the workpiece 100, and the residue 102 is dropped downward.

  According to such an elastic roll 31 with projections, the shape of the residue 102 remaining in the punched portion 101 is relatively small, for example, about 5 mm per piece, or relatively small, such as a circular shape about 10 mm in diameter. Can be dropped down well.

  11 and 12 show a protruding elastic roll 31A, which is a modification of the protruding elastic roll 31, and, like the protruding elastic roll 31, a large number of truncated cones are formed on the outer periphery of the shaft core 32. FIG. An elastic material 34 including a soft rubber material provided with protrusions 33 is wound around. Further, on the inner surface at a position corresponding to each projection 33 in the elastic material 34 such as a soft rubber material, a recess 35 for increasing elasticity is provided.

  When such an elastic roll 31A with projections is used, as shown in FIG. 12, the projections 33 are formed on the upper surface of the residue 102 that rotates above the workpiece 100 and remains on the punched portion 101 of the workpiece 100. When contacting and dropping the dregs 102 downward, the concave portion 35 at a position corresponding to the projection 33 is bent, and the dregs 102 is moved in a state where the elasticity is enhanced compared to the elastic roll 31 with projection described above. It can be dropped down.

  That is, since the elastic roll 31 with protrusions described above does not have the recess 35, the workpiece 100 is relatively thick, and thus the elastic roll 31A with protrusions has the recess 35, so that the thickness of the work 100 is small. It is suitable for scrap removal of relatively thick ones.

Next, the brushed roll pair 41 will be described with reference to FIGS.
The pair of rolls with brushes 41 includes a front-stage upper roll 43 and a front-stage lower roll 44 in which a brush 42 is planted on the entire outer periphery, arranged vertically with the conveyance path 5 interposed therebetween, and a rear-stage upper roll 45 and a rear-stage lower roll 46 disposed on the conveyance path 5. There are a total of four components arranged vertically, and these are rotationally driven by the roll drive unit with brush 66 so that the rotational directions of the upper and lower and adjacent ones are different as indicated by arrows in FIG. ing.

  More specifically, as shown in FIG. 14, the front stage upper roll 43 rotates above the conveyance path 5 so that the brush 42 faces the conveyance direction (arrow x direction) of the workpiece 100 from above the conveyance path. By rotating and scraping off the residue 102 remaining on the punched portion 101 of the workpiece 100, the residue 102 is removed above the workpiece 100.

  The front lower roll 44 rotates below the conveyance path 5 and rotates so that the brush 42 faces the conveyance direction (arrow x direction) of the workpiece 100 from below the conveyance path, and remains in the punched portion 101 of the workpiece 100. By scraping off the scrap 102, the scrap 102 is removed below the workpiece 100.

  The rear-stage upper roll 45 rotates above the conveyance path 5, and the brush 42 rotates in the same direction as the conveyance direction from above the conveyance path with respect to the conveyance direction (arrow x direction) of the workpiece 100. By scraping off the residue 102 remaining on the substrate 101, the residue 102 is removed above the workpiece 100.

  The rear lower roll 46 rotates below the conveyance path 5, and the brush 42 rotates in the same direction as the conveyance direction from below the conveyance path with respect to the conveyance direction (arrow x direction) of the workpiece 100. The residue 102 is scraped off to remove the residue 102 below the workpiece 100.

  According to the pair of brush rolls 41 having such a configuration, the protruding direction from the punched portion 101 of the dregs 102 remaining on the punched portion 101 of the workpiece 100 is obliquely forward along the conveying direction of the workpiece 100. In this case, it can be efficiently removed from the punched portion 101 either diagonally forward or diagonally forward or diagonally downward in the direction opposite to the conveying direction of the workpiece 100.

  Further, according to the brush-equipped roll pair 41 having such a configuration, the brushes 42 of the front stage upper roll 43 and the front stage lower roll 44, the rear stage upper roll 45 and the rear stage lower roll 46 scrape off the upper surface and the lower surface of the workpiece 100. Therefore, fine powder, dust, etc. leaking from the punched portion 101 adhering to the upper and lower surfaces of the workpiece 100 can also be removed.

  According to the paper piece paper dust removing device 1 of this embodiment described above, the elastic material 11 of the elastic rolls 11A, 11B, and 11C and the punched portion 101 of the workpiece 100 remain in the punched portion 101 due to the distortion of the outer peripheral portion. The scraps 102 can be efficiently pressed down and removed, and the elastic rolls 11A, 11B, and 11C can impart a conveying force to the workpiece 100 in the conveying direction.

  In addition, since the divided roll portion of the second-stage elastic roll 11B is arranged so as to complement the gap 17 between the divided roll portions of the first-stage and third-stage elastic rolls 11A and 11C, the work 100 It is possible to remove debris from the punched portion 101 distributed over the entire workpiece 100 without generating a blind spot region for the punched portion 101. As described above, in the present invention, the elastic material which is not divided around the outer periphery of the shaft core 15 is wound around the outer periphery of the shaft core 15 without winding the divided arrangement of the elastic material 16. Of course you can.

  In addition, the elastic roll 11D having a deformed roll shape in which the cross-sectional shape in the rotation direction orthogonal to the axial direction has a four-leaf substantially circular shape, and two locations along the rotation direction on the outer peripheral portion and having a predetermined interval By using the elastic roll 11E in the shape of a deformed roll having the concave portion 19, the pressing force when pressing and removing the residue 102 remaining on the punched portion 101 of the workpiece 100 can be changed. It is possible to accurately cope with a case where the type and thickness of a certain workpiece 100 are changed.

  Further, by the elastic roll 31A with protrusions and the elastic roll 31A having protrusions 35, the shape of the residue 102 remaining in the punched portion 101 is relatively small, for example, about 5 mm per piece, or circular, about 10 mm in diameter. A relatively small object or the like can be efficiently dropped downward, and the workpiece 100 can be widely used for a relatively thick or relatively thin thickness.

  Further, according to the air nozzles 12A to 12D, high-pressure air is blown onto the residue 102, and the residue 102 remaining in the punched portion 101 is dropped downward, including those that cannot be removed by the elastic roll 11A. be able to.

  Further, according to the pair of rolls with brush 41, even if the protruding direction of the falling dregs 102 from the punched portion 101 is in various directions, each can be efficiently removed from the punched portion 101, and the workpiece can be removed. Fine powder, dust and the like leaking from the punched portion 101 adhering to the upper and lower surfaces of 100 can also be removed.
