Definitions

  • the present invention relates to a sheet brake system for braking printed sheets, according to the preamble of claim 1.
  • a bow brake system in which the brake elements are driven by a common square shaft.
  • the square shaft is drivingly connected to each brake element via a gear transmission.
  • a disadvantage of this sheet brake system is that its constructive concept allows no adjustment of the brake elements either in a position parallel to the sheet running direction and in an inclined position to the sheet running direction. The oblique position to the sheet running direction could, however, in some print jobs a cross-tightening the sheet be advantageous.
  • the gear transmission is inevitably fraught with backlash, which acts as a so-called backlash under dynamic load of the gear transmission.
  • a particularly large dynamic load of the gear transmission would be given if the sheet brake system would be operated as a so-called clocked sheet brake system, wherein the brake elements with the delivery cycle of the sheet are correspondingly delayed and accelerated.
  • a strong wear of the gear mechanism and consequently an increase of the backlash which can lead to the fact that the brake elements no longer run synchronously with each other and the sheet stack on which the sheet brake system deposits the sheets, is inaccurate and unstable.
  • a sheet brake system in which suction devices are arranged for pressing the sheet against the brake rollers at such a distance below the upper generatrix of both brake rollers that they do not touch the underside of the sheets.
  • the suction devices may be formed as a suction tube, on which rollers are arranged, on which the brake rollers are supported.
  • the suction pipe forms a negative pressure in the gap between the brake rollers.
  • the primary object of the invention is to provide a sheet brake system in which the brake elements can be exchanged easily.
  • the invention has the further object of providing a sheet brake system whose format adjustability can be easily automated.
  • the invention has the further object to provide a sheet brake system that can be easily adapted to different print jobs, some of which require a bow lift and others not.
  • it is a still further object of the invention to provide a sheet brake system that is highly resilient dynamically.
  • offset eccentrically is meant that the roll axis and the orbital axis are not coaxial with each other or are not aligned with each other or are not one and the same geometric axis.
  • the roller axis is offset eccentrically relative to the single axis of rotation of the respective brake element.
  • the brake elements may in this case be, for example, brake discs, wherein each brake disc has a geometric axis of rotation which forms said single geometric axis of rotation and around which the brake disc rotates.
  • the roller axis is offset eccentrically relative to each of the revolving axes of the respective braking element.
  • the brake elements may be formed here, for example, as endless brake bands or belts, which each revolve around several roles and thus wrap around them.
  • the geometric axes of rotation of the rollers form a plurality of revolution axes about which the respective brake band or the respective brake belt rotates.
  • the drive roller rotates about the geometric roller axis.
  • the roller axis is aligned parallel to the axis of rotation of the respective brake disc at least in a certain setting of the sheet brake system.
  • the roller axis is at least in a particular setting of the sheet brake system aligned relative to the axes of rotation of all looped by the respective brake band or belt rollers in parallel.
  • the sheet brake system according to the invention is advantageous in various respects.

  • An adjustment of the brake elements along the drive roller which takes place for the purpose of setting the format of the sheet brake system can be motorized or automated without any problems.
  • the constructive concept allows a mounting of the brake elements, in which the brake elements can be pivoted relative to the conveying or running direction of the sheet either in parallel and for Bogenquerstraffung in oblique positions.
  • By frictional contact backlash is avoided, so that the sheet brake system is suitable for use as a clocked sheet brake system.
  • the braking elements are correspondingly periodically delayed and accelerated with the delivery cycle of the printed sheet.
  • the brake elements also run synchronously with each other when the transmission over which the brake elements are driven is exposed to the highly dynamic alternating loads of a pulsed sheet braking system.
  • the braking elements - as already mentioned - designed as endless brake bands or belts and wrap around the brake elements, the drive roller not.
  • the drive roller is thus outside of the brake bands or belts and the latter is not inserted through the brake bands or straps.
  • each brake element is assigned a friction wheel, which rests on the drive roller to form the friction contact. Accordingly, the rolling on the drive roller friction wheels are driven by the drive roller rotation. The rotational movement of the friction wheels can be transmitted in different ways to the brake elements, as will be explained below.
