Definitions

  • the invention relates to a method for rotary cutting of band-shaped material in accordance with the preamble of claim 1.
  • such devices have a rotary cutting roller having at least one cutter on its exterior surface, by means of which the band-shaped material is cut.
  • the band-shaped material runs through a gap between the rotary cutting roller and a counter-tool.
  • Advancing the cutter in the direction toward the counter-tool takes place by means of barrel rings, which customarily are provided on the rotary cutting roller.
  • the cutter can slightly project past the exterior circumference of these barrel rings, can terminate flush with them, or can be slightly set back from them. This is a function of the respective band-shaped material to be cut.
  • the grinding device in accordance with the invention is employed during the normal cutting process and when needed.
  • the device can be pivoted out and/or brought into contact mechanically, pneumatically and/or hydraulically. Grinding time can be selected to be as long as desired and can also be set. Furthermore, the contact pressure, and therefore the rate of removal, can be freely selected and set.
  • the grinding element of the grinding device can be matched to the barrel ring. During the grinding process, the grinding element or the complete grinding device can be oscillatingly moved transversely to the direction of rotation by means of springs and pneumatic assistance, so that even removal occurs. Depending on the requirements, the grinding element can be broader or narrower than the barrel ring. Cleaning rollers can be placed ahead or behind, which pick up dust and dirt.
  • Cleaning can also be performed by fixed lips or strippers, and a cleaning additive or grinding agent can be added.
  • the device can be placed, or respectively pivoted in, with or against the direction of rotation of the barrel ring. If the grinding process is performed on the counter-cylinder, then as a rule in the areas where the barrel rings are seated. Because of the pivot device, the device is independent of the diameters of the rollers.
  • Another stripper for example a blade stripper, can be placed ahead of or behind the cleaning elements.
  • the grinding element can also be composed of several different grinding materials, for example as a compound grinding element, or respectively a sandwich grinding element.
  • the shape of the grinding element can be arbitrary, for example, flat, curved, concave, convex or prism-shaped.
  • a compressed air nozzle can be attached to the grinding device for cooling the barrel ring. If necessary for the result of grinding, the grinding device can be moved in or against the running direction of the barrel ring in addition to the transverse movement or independently thereof. Moreover, the contact pressure can be set at different strengths, or it can be additionally supplied in a pulsed manner.
  • FIG. 1 a schematic representation of the grinding device in accordance with the invention
  • FIG. 2 a schematic representation of an oscillating device for a grinding element
  • FIGS. 3 a to 3 d different shapes of the grinding element.
  • a barrel ring 1 of a rotary cutting cylinder and a counter-tool 2 are represented in FIG. 1. Both the barrel ring 1 and the counter-tool 2 rotate in the direction of the arrows 3 and 4 .
  • a grinding device identified as a whole by 5 , is provided on the top of the barrel ring 1 . This grinding device is seated, pivotable in the direction of the two-headed arrow 7 , in a bearing 6 . Moreover, the grinding device 5 is charged with a pressure force in the direction of the arrow 8 by means of a suitable device and is pressed on the exterior surface of the barrel ring 1 in this way.
  • a grinding element 9 which is interchangeably provided in a housing 10 of the grinding device 5 , rests on the grinding ring 1 .
  • Cleaning pods 11 and 12 are provided ahead of and behind the grinding element 9 , which clean and, if required moisten, the surface of the barrel ring 1 .
  • An oscillating device 13 is represented in FIG. 2, by means of which the grinding element 9 is oscillatingly moved in the direction of the axis 14 of the barrel ring, and therefore in the direction of the two-headed arrow 15 .
  • the grinding element 9 is here driven by a mechanical, hydraulic or pneumatic drive 16 , for example a cylinder or the like.
  • a drive rod 17 here acts directly on the grinding element 9 , while the grinding element 9 is supported on the opposite side on a spring 18 (helical compression spring).
  • FIGS. 3 a to 3 d Different shapes of the grinding element 9 are represented in FIGS. 3 a to 3 d .
  • FIG. 3 a shows a grinding element 9 with a level grinding surface, wherein the grinding element 9 furthermore can be moved oscillatingly in the direction of the two-headed arrow 19 , i.e. in the direction of rotation (arrow 3 ) of the barrel ring 1 and opposite this direction of rotation.
  • FIG. 3 b shows a grinding element 9 with an arch-shaped convex grinding surface
  • FIG. 3 c shows a grinding element 9 with an arch-shaped concave grinding surface.
  • FIG. 3 d shows a grinding element 9 with a prismatic (V-shaped) grinding surface.
