Definitions

  • the invention relates to a rotary rotary printing press with a plurality of printing units arranged in succession and a printing unit for flying printing plate changes, in which one printing plate cylinder transfer cylinder for the printing plate change can be stopped and the other can be turned on a common, rotating impression cylinder on at least one of the printing unit cylinder axes of the printing unit for flying printing form changes, two gears are positioned and, in impression mode, the drive of one printing plate cylinder pair of transfer cylinders can be uncoupled from the main drive supplied via the impression cylinder and connected to an auxiliary drive via couplings.
  • EP 0196 019 A2 describes a web-fed rotary offset printing press with a printing unit known for flying plate changes.
  • both the upper and the lower printing unit can be connected to one and the same auxiliary drive.
  • the disadvantage of this device is the fact that when the material web is printed on both sides, the impression cylinder can be pivoted out of contact with the printing units and acts as a paper guide roller. There is a risk that during long-term operation in the perfecting mode, ink will deposit on the surface of the impression cylinder and dry there over time.
  • the object of the invention is to improve the user-friendliness and the smoothness of a printing unit arranged upstream of a plurality of printing units arranged in succession.
  • this object is achieved in that the printing group cylinders are in a substantially vertically extended installation position and both the printing group cylinders of an upper printing unit and the printing group cylinders of a lower printing unit can each be switched off from the impression cylinder.
  • the vertical arrangement of the printing unit cylinders in the impression unit ensures the greatest possible rigidity of the cylinders in the impression unit against deflection. Due to the elongated construction, the main components of the forces caused by the rotating components act in both Total printing units against each other and cancel each other out in their effect. This minimizes streaking in print and increases print quality. Since the individual printing unit cylinders of a printing unit can each be parked together by the impression cylinder, the parking eccentrics can be dimensioned small.
  • the printing group cylinders of the upper printing unit and the printing group cylinders of the lower printing unit are each arranged symmetrically with respect to the impression cylinder.
  • the printing unit cylinders of the upper printing unit and the lower printing unit each have both a multi-plate and a tooth coupling.
  • the acceleration of the printing unit cylinders of the corresponding printing unit is initiated via the multi-plate clutch, while the main drive takes over the drive of the respective printing units via the toothed coupling after acceleration to machine speed.
  • a rotary encoder is arranged on each printing unit cylinder of a printing unit.
  • the tooth coupling respectively assigned to the pressure units is mounted separately and not on the rubber cylinder journal, so that bending of the journal due to the weight of the coupling cannot occur.
  • FIG. 1 shows a side view of the drive side of the impression mechanism with auxiliary drive.
  • An impression unit 1 located in front of the successively arranged printing units is driven via a longitudinal shaft 2 by a main drive (not shown) of a rotary printing press.
  • the longitudinal shaft 2 opens via a coupling 3 into a gear 5 flanged to a side wall 24.
  • the longitudinal shaft 2 is supported by a shaft bearing 4 in the gear 5 and drives a worm 6 meshing with a worm wheel 7.
  • the output 8 of the worm gear is transmitted to an intermediate wheel 9 which drives a counter pressure cylinder 11 via a further intermediate wheel 10.
  • two printing unit cylinders namely an upper printing form cylinder 12 and an upper transfer cylinder 13, which form an upper printing unit 14, are arranged.
  • a printing unit 17 is arranged below the impression cylinder 11 and comprises a lower transfer cylinder 15 and a lower printing form cylinder 16.
  • An intermediate gear 20 serving as a distributor wheel is driven by an auxiliary drive 22 flanged to the side wall 24 via a pinion 21, which acts on both the upper multi-plate clutch 18 and the lower multi-plate clutch 19.
  • the impression cylinder 11 is, according to the configuration shown in FIG. 1, continuously connected via the intermediate wheels 9 and 10 to the transmission 5 acted upon by the main drive via the longitudinal shaft 2.
  • Fig. 2 shows a schematic representation of the parking mechanism of the individual printing unit cylinders from the operating side of the impression unit. In comparison to FIG. 1, this is a mirror image.
  • Adjustment forks 26 are located on traverses 25 which can be actuated by means of actuating cylinders and which are connected via an actuating linkage 27 to the printing unit cylinders 12, 13 of the upper printing unit 14 and the printing unit cylinders 15 and 16 of the lower printing unit 17.
  • both printing unit cylinders 12, 13 of the upper ones are switched off simultaneously Small printing eccentric can be used and printing unit 14 and simultaneous parking of both printing unit cylinders 15, 16 of lower printing unit 17 can be used.
  • an intermediate wheel 31 is driven, which meshes with gear wheels of gear clutches 29 and 30, which in turn mesh with gear wheels of the transfer cylinders 13 and 15, respectively.
  • One of the two pressure units 14 and 17 can each be connected to the main drive via the actuatable toothed couplings 29 and 30.
  • FIGS. 4 and 5 each show periodically occurring angular positions of the individual printing unit cylinders during their rotation.
  • What the 5 relates to a rolling of the channels 33 from the impression cylinder 11 and the lower transfer cylinder 15.
  • the channels 33 of the printing unit cylinders 12 and 13 of the upper printing unit 14 roll on one another.
  • a channel rollover occurs alternately simultaneously, either between the printing form cylinder 12 and the transfer cylinder 13 of the upper printing unit 14 or a channel rollover of the printing unit cylinders 15 and 16 of the lower printing unit 17.
  • FIG. 6 shows a cross section running from the drive side to the operating side of an impression mechanism according to the invention.
  • the drive introduced into the impression mechanism 1 by the main drive is transmitted via a worm 6 and a worm wheel 7 and from there reaches the output 8.
  • the output gear 8 is received by bearings 36 on a pin fastened to the side wall 24.
  • the intermediate gear 9, with bearings 36 arranged on a bearing journal 34 on the side wall 24, transmits the drive via an intermediate gear 10, not shown here, which lies above the intermediate plane, to a drive gear 40 of the impression cylinder 11.
  • the impression cylinder 11 is through cylinder bearings 37 in the side walls 24 and 35 recorded and stationary.
  • the drive runs from the drive wheel 40 to a gearwheel 41 which is supported by bearings 36 on the journal of the transfer cylinder 15 and whose torque transmission can be switched on and off by the gear coupling 29.
  • the transfer cylinder 15 is mounted in cylinder bearings 37, which, in contrast to the mounting of the impression cylinder 11, are accommodated in eccentric bushings 28, on which actuating forks 26 are formed. These adjusting forks 26 are also opposite Adjustment forks 26 are arranged, which are attached to a cross member 25.
  • the actuating linkage 27 between the actuating forks 26 has not been shown for reasons of clarity.
  • the traverse 25 is actuated by an actuating cylinder 39 mounted on the side wall 35, as a result of which the printing couple cylinders 15 and 16 of the lower printing unit 17 can be jointly disengaged from the impression cylinder 11.
  • the cylinder journal of the transfer cylinder 15 has a further gear 42 which meshes with a gear 44, which in turn is mounted on a stub shaft with a clutch gear 43 and the associated multi-plate clutch 19.
  • the clutch wheel 43 of the multi-plate clutch 19 is driven by the intermediate wheel 20, which is supported by bearings 36 on a journal 45 on the side wall 24.
  • the intermediate gear 20 meshes with a pinion 21 of the auxiliary drive 22 which is fastened to the impression mechanism 1 with the flange 23.
  • a change from the upper printing unit 14 to the lower printing unit 17 is briefly outlined below.
  • a rotary encoder 38 arranged on the cylinder journal of the upper transfer cylinder 13 penetrating the side wall 35 serves to identify the correct engagement position and to compare the rotational speed after the acceleration by the auxiliary drive 22. Since the drive currently runs via the main drive, the upper multi-plate clutch 18 is disengaged.
  • the lower printing unit 17 is accelerated after the printing form change.
  • the tooth coupling 30 is still disengaged;
  • the lower pressure unit 17 is accelerated via the auxiliary drive 22 and the components 21, 20, 43, 44 and 42 approximately to machine speed.
  • a rotary encoder 38 arranged on the cylinder journal of the lower transfer cylinder 15 on the operator side, both the engagement position for the tooth clutch 30 and the correspondence of the machine speeds are determined.
  • the multi-plate clutch 18 engages the upper pressure unit 14, at the same time the multi-plate clutch 19 of the lower pressure unit 17 and the toothed clutch 29 of the upper pressure unit 14 disengage. Characterized in that the pressure unit 14 is connected to the auxiliary drive 22 by engaging the upper multi-plate clutch 18, the upper pressure unit 14 can be braked by the latter and prepared for changing the printing form.
