Definitions

  • the invention relates to a drive for expansion segments for diameter adjustment on the folding cylinder of rotary printing machines according to the preamble of claim 1.
  • a continuous material web for example a paper web
  • a folding apparatus of the printing press is printed and cut into signatures in the cutting unit of a folding apparatus of the printing press and then folded.
  • One possible type of fold is the transverse fold which is perpendicular to the direction of movement of the signatures.
  • the leading edge of the signature is held either before or after the cutting process by mandatumadeln or grippers on a folding cylinder, which is designed for example as folding blade.
  • the signature is pushed along its center line by a folding blade arranged in the folding blade in a jaw or in folding rollers, so that a transverse fold is formed.
  • An expansion segment refers to a portion of a cylinder that forms an outer portion of the cylinder and is adjustable to define the effective diameter of the cylinder.
  • a folding cylinder with an adjustable expansion segment is known, which is arranged on a cylinder base between carriers, wherein the expansion segment forms the effective cylinder diameter.
  • An adjusting device consisting of an eccentric designed camshaft on which the expansion segments are arranged, serves to adjust the expansion segments and thus to set the effective diameter.
  • a device for adjusting the diameter of a folding cylinder is known. In this device, the diameter adjustment is done automatically or via a hand crank, which initially drives a gear train and thereby-Gleitbasen adjusted and thus changed the diameter of the folding cylinder by engaging in bands. Further prior art is known from US 5,313,883 A1 known
  • the advantage of the solution according to the invention is that the drive of the eccentric screws by an endless drive means and / or adjusting means, for example a chain, a toothed belt or otherwise ausgestalteter belt drive, accomplished.
  • the endless drive means and / or adjusting means is arranged on the folding cylinder such that it at least partially wraps around the drive wheels of the eccentric spindles.
  • the drive wheels and tension rollers are configured according to the respective endless drive means used and / or adjusting means.
  • Fig. 1 shows a folding cylinder 1.
  • expansion segments 2 are arranged. Outer surfaces 3 of the expansion segments 2 form the effective diameter of the folding cylinder 1.
  • the expansion segments 2 are mounted on an eccentric spindle 5 via support elements 4.
  • the eccentric spindle 5 is, not shown in detail, arranged between carrier elements 6 on the folding cylinder 1.
  • a drive wheel 7 is arranged on the end, for example on the drive side formed by the carrier element 6, (see FIG Fig. 2 ).
  • tension rollers 8 are arranged, wherein a tension roller 8 is connected to a transmission gear 9.
  • the tension rollers 8 are preferably arranged stationary.
  • the folding cylinder 1 is mounted on a shaft 10.
  • a central drive wheel 11 is rotatably mounted on the shaft 10.
  • the central drive wheel 11 is connected to the transmission gear 9 above an endless drive means 12 in connection.
  • the drive wheels 7 and the tension rollers 8 are connected via a further endless drive means 13, referred to here as adjusting means 13 in connection.
  • the drive wheels 7 and tension rollers 8 are at least partially looped by the adjusting means 13.
  • the central drive wheel 11 is, not shown in detail, connected to a drive.
