Definitions

  • the invention relates to a device for Rotary cutting of sheet material according to the Preamble of claim 1.
  • Such devices show in usually a rotary cutting roller on its Outer surface carries at least one cutting edge with which the sheet material is cut.
  • This web-like material passes through a gap between the rotary cutting roller and a counter tool.
  • the Infeed of the cutting edge in the direction of the counter tool takes place via races, which are usually on the Rotary cutting roller are provided.
  • the invention has for its object a device of the type mentioned at the outset in such a way that relatively easy due to the wear of the cutting edge itself changing gap can be adjusted.
  • the grinding device according to the invention is during the normal cutting process and used if necessary.
  • the device can be mechanical, pneumatic and / or be hydraulically swung open and / or pressed.
  • the Grinding time can be chosen as long as you like can be set. Furthermore, the contact pressure and thus the removal rate can be freely selected and set.
  • the Grinding element of the grinding device can on the race be coordinated.
  • the grinding element or the complete Grinding device can be by springs and pneumatic Support during the grinding process across Direction of rotation can be moved oscillatingly, so that a uniform removal occurs. Depending on the requirement the grinding element is wider or narrower than the race his. It can be superior or subsequent Cleaning rollers are provided, the dust and Take up dirt.
  • the cleaning can also be done by fixed lips or wipers and it can a cleaning additive or an abrasive become.
  • the facility can also be used as needed or placed against the direction of rotation of the race or be swung open. If the grinding process takes place on Counter cylinder, then usually in the areas where sit on the races. Because of the Swivel mechanism is independent of the device the roller diameters.
  • the cleaning elements can still a scraper can be placed in front or behind, e.g. on Blade wipers.
  • the grinding element can also be made several different grinding materials be composed, e.g. a compound grinding element or Sandwich grinding element.
  • the shape of the grinding element can be arbitrary, e.g. flat, arched, concave, convex or prismatic.
  • the Grinding device in addition to the transverse movement or regardless of in or against the direction of the Moving ring.
  • the pressure force can be set differently or additionally be applied pulsating.
  • a race 1 of a rotary cutting cylinder and a counter tool 2 is shown. Both the race 1 and the counter tool 2 run in the direction of arrows 3 and 4.
  • a grinding device generally designated 5 is provided on the upper side of the race 1.
  • This grinding device is pivotally mounted about a bearing 6 in the direction of the double arrow 7.
  • the grinding device 5 is acted upon in the direction of the arrow 8 by a suitable device with a compressive force and is thus pressed onto the outer surface of the race 1.
  • Cleaning balls 11 and 12 are provided in front of and behind the grinding element 9, which clean and, if necessary, wet the surface of the race 1.
  • FIG. 2 shows an oscillation device 13 with which the grinding element 9 is moved in an oscillating manner in the direction of the axis 14 of the race 1 and thus in the direction of the double arrow 15.
  • the grinding element 9 is driven by a mechanical, hydraulic or pneumatic drive 16, for example a cylinder or the like.
  • a drive rod 17 acts directly on the grinding element 9, whereas the grinding element 9 is supported on the opposite side by a spring 18 (helical compression spring).
  • FIGS. 3a to 3d show different forms of the Sanding elements 9 shown.
  • Figure 3a shows a Grinding element 9 with a flat grinding surface, the Grinding element 9 also in the direction of the double arrow 19 oscillating, i.e. in the direction of rotation (arrow 3) of the race 1 and is movable against this direction of rotation.
  • the figure 3b shows a grinding element 9 with an arcuate shape convex grinding surface and
  • Figure 3c shows a Grinding element 9 with an arcuate concave Grinding surface.
  • Figure 3d shows a grinding element 9 with a prismatic (V-shaped) grinding surface.
