Definitions

  • the invention relates to a printing unit according to the Preamble of claim 1.
  • EP 0 644 048 A2 is one Rotary printing machine with rubber and plate cylinders known. These rubber and plate cylinders are in pairs through a mechanical coupling for their common Drive grouped into cylinder groups. Such Cylinder group is each one of its own Drive motor driven.
  • WO 95/24314 discloses a bridge printing unit which is powered by a separate drive motor.
  • the plate cylinders each have their own Provide auxiliary drive motor for maintenance purposes.
  • the US 40 72 104 A shows printing units, their drive via a common longitudinal shaft. All cylinders the pressure units are form-fitting by means of gears connected. Rubber and plate cylinders are over one Harmonic drive gear for circumferential register adjustment connected.
  • EP 06 99 524 A2 describes variants for the drive of printing units.
  • EP 06 21 133 A1 teaches the cylinders one Printing unit each with its own electric motor Mistake.
  • the invention has for its object a To create printing unit.
  • the non-printing area does not increase due to the channels of the rubber cylinders.
  • the outlay on the electrical equipment is considerably less.
  • a plate cylinder to the blanket cylinder, a second plate cylinder can be stopped, for example for a plate change.
  • the printing unit is shown in the drawing and is described in more detail below.
  • a printing unit 1 of an offset rotary printing press is shown in a so-called bridge construction.
  • This printing unit 1 is essentially two forme and transfer cylinders 2, 3, 4, 6, z. B. plate and rubber cylinders 2, 3, 4, 6 formed, which interact in pairs.
  • the two rubber cylinders 4, 6 form a printing point 7 in their contact zone, in which, for example, a paper web 8 is printed.
  • These plate and blanket cylinders 2, 3, 4, 6 are provided at both ends with pins 9, 11-14, 16-18, which are mounted in side frames 19, 21 of the offset rotary printing press.
  • Plate and rubber cylinders 2, 3, 4, 6 are arranged in a known manner, for example by means of eccentric bushes, on and off.
  • the plate cylinders 2, 3 can be arranged on and off with respect to the associated rubber cylinders 4, 6.
  • the pins 9, 12, 14, 17 of the plate and rubber cylinders 2, 3, 4, 6 extend through the side frame 19.
  • the pins 14, 17 of the two rubber cylinders 4, 6 and the first plate cylinder 2 are provided with cooperating gears 22, 23, 24.
  • These three cylinders 2, 4, 6 are driven by a common drive 26, a position-controlled electric motor 26.
  • This electric motor 26 is arranged, for example, directly on the first plate cylinder 2, but the drive 26 can also be provided on any of the three cylinders 2, 4, 6 directly or indirectly.
  • the second plate cylinder 3 is provided with its own drive 27, which is designed as a position-controlled electric motor 27.
  • the drive 26 of the three cylinders 2, 4, 6 and the drive 27 of the second plate cylinder 3 are synchronized with each other.
  • the third rubber cylinder forms a second pressure point with the second or first rubber cylinder.
  • the third rubber cylinder is then also provided with a gear.
  • the Z. B. engages in the gear of the interacting rubber cylinder.
  • the third blanket cylinder is mechanical, e.g. B. positively coupled to the first and second rubber cylinders and to the first plate cylinder.
  • the third plate cylinder is in turn provided with its own position-controlled electric motor,
  • the Rubber cylinders are not directly together, but it is a additional pressure cylinder, a so-called Satellite cylinder, provided.
  • a so-called Satellite cylinder With this pressure cylinder each employed rubber cylinder forms a pressure point.
  • This pressure cylinder is preferably with a gear provided that in a gear of a rubber cylinder intervenes.
  • the pressure cylinder is mechanical, e.g. B. positively coupled to a rubber cylinder. Is too it is possible to have the printing cylinder with its own independent drive, e.g. B. a position-controlled To provide electric motor.
  • gears 22, 23, 24 can mechanical coupling, e.g. B. for positive Drive connection of cylinders 2, 4, 6 also others Means such as B. timing belt may be provided.
  • the gear 22 of the plate cylinder 2 can for example also be uncoupled from the gear 23 of the associated rubber cylinder 4.
  • the gear 22 can be axially displaceably mounted on the pin 9 of the plate cylinder 2, so that it can be disengaged with respect to the gear 23 of the rubber cylinder 4.
  • a gear 28 can also be arranged, which can be selectively brought into engagement with the gear 24 of the associated rubber cylinder 6. This gear 28 is slidably mounted on the pin 12 of the plate cylinder 3.
