Definitions

  • the invention relates to a cutting device for cross-cutting running webs, in particular in a folder arranged downstream of a rotary printing press, according to the preamble of claim 1.
  • EP 03 64 864 A2 describes a cutting device in a folder of a rotary printing press.
  • a cutting cylinder provided with two cutting knives interacts with a collecting cylinder having three cutting strips. While cutting a web into arcs, the respective cutting knife dips into the corresponding cutting bar.
  • a disadvantage of this cutting device is that the cutting knives perform cycloid-like movements in the cutting strips, whereby the z.
  • B. existing elastic plastic cutting strips are subject to high wear.
  • the invention has for its object to provide a cutting device for cross-cutting of running webs, in which wear of a cutting bar and bending forces and cutting forces acting on a cutting knife in the web running direction are minimized.
  • cutting knives can be used in the cutting device according to the invention, the knife edge of which is not equidistant from the axis of rotation of the cutting cylinder, such as. B. wedge-shaped, V-shaped or arrow-shaped cutting knife.
  • the result of this is that the very large cutting forces which have so far occurred abruptly are substantially reduced. This makes it possible to use thicker sheets or to cut more layers of webs and to achieve higher production speeds.
  • the load on the cutting device caused by vibrations is reduced.
  • the maintenance cycle for replacing the cutting blades is extended when using rotating cutting cylinders with several cutting blades, since the number of cutting blades increases the number of cuts that can be achieved per maintenance cycle.
  • the cutting device according to the invention is shown in the drawing and is described in more detail below.
  • a cutting cylinder support 3 and a collecting cylinder 4 are rotatably supported about their parallel axes of rotation 6, 7.
  • the cutting cylinder carrier 3 rotates in the same direction as the collecting cylinder 4 during a cutting operation.
  • the cutting cylinders 8, 9 rotate in opposite directions to the collecting cylinder 4 during a cutting operation.
  • the collecting cylinder 4 serves as a counter cylinder for the cutting cylinders 8, 9 and is therefore provided with cutting bars 16 which are fixed to the cylinder.
  • the cutting cylinders 8, 9 are driven by means of a planetary gear from a main drive gear train.
  • This approximately radial movement has a small, parallel offset from the ideal radial direction, this offset being able to be minimized by varying the radii r3, r4 and r13.
  • Both the relevant move Cutting knife 13 as well as the corresponding cutting bar 14 with approximately web speed.
  • the cutting knife 13 moves radially towards the collecting cylinder 4, cuts through the web 28 and penetrates into the cutting bar 16.
  • the axes of rotation 6, 7, 11 and 12 and the cutting knife 13 lie on a common straight line.
  • a radial speed of the cutting knife 13 is zero and the excavation movement of the cutting knife 13 begins.
  • the excavating movement of the cutting knife 13 also takes place radially with respect to the collecting cylinder 4.
  • Fig. 4 shows a second embodiment of the cutting device according to the invention in which the collecting cylinder 4 is provided with three cutting strips 16.
  • Fig. 5 shows a third embodiment of the cutting device according to the invention in which the collecting cylinder 4 is provided with three cutting bars 16 is.
  • FIG. 6 shows a fourth exemplary embodiment of the cutting device according to the invention in which the collecting cylinder 4 is provided with three cutting strips 16.
  • Fig. 7 shows a fifth embodiment of the cutting device according to the invention in which the collecting cylinder 4 is provided with three cutting strips 16.
  • Fig. 8 shows a sixth embodiment of the cutting device according to the invention in which the collecting cylinder 4 is provided with five cutting strips 16.
  • Fig. 9 shows a seventh embodiment of the collecting cylinder 4 is provided with five cutting strips 16.
  • FIG. 10 shows an eighth exemplary embodiment of the cutting device according to the invention in which the collecting cylinder 4 is provided with five cutting strips 16.
  • FIG. 11 shows a ninth exemplary embodiment of the cutting device according to the invention in which the collecting cylinder 4 is provided with five cutting strips 16.
  • At least one cam which is stationary with respect to the side frame 1 is provided, which, by means of a lever arm connected to the cutting cylinder 8, the cam roller of which rolls on the cam, generates the necessary swiveling movement opposite to the direction of web travel and the return movement after the cut has been made.
