Definitions

  • the invention relates to a drive for a processing machine, in particular for a printing machine with at least one printing plate having a plate or forme cylinder, according to the preamble of the independent claim 1.
  • a drive of this kind is out DE 42 41 807 A1 known.
  • the printing units are coupled via a gear train (gear transmission) on the drive side.
  • a motor-driven gear train is provided for all cylinder transporting the printing material, in particular the blanket cylinder and all cylinders leading to the printing material (eg printing cylinder, beater, storage drum, transfer drum).
  • each plate cylinder is coupled on the drive side with the first gear train.
  • the drive designs have encoders for the movement variables and are circuit-coupled with a control / regulating device.
  • Another drive is off EP 0 834 398 A1 which allows a high degree of flexibility with regard to simultaneous or out-of-phase executable processes in a sheet-fed press.
  • Serving the sheet transport cylinder or drums and arranged in the individual printing plate or forme cylinder can be driven by a common gear train of at least one drive motor of a main drive.
  • the plate or forme cylinders are each assigned a remote-controlled separate drive, by means of which the plate or forme cylinder can be driven independently of the drive of the remaining cylinders or drums as a function of the switching states of the clutches in a predetermined manner.
  • the clutch assigned to a plate / forme cylinder is preferably arranged in the drive train between blanket cylinder and plate cylinder or forme cylinder.
  • the invention is based on the object to provide a drive of the type mentioned above, which is universally applicable in addition to the printing operation, especially in setup mode and reduces setup times noticeably.
  • a first advantage of the invention is that - starting from a main drive with common gear train for the substrate transporting cylinders and drums and arranged in the individual printing units plate or forme cylinder - such a drive to reduce set-up times in a processing machine, in particular in offset printing machines or flexographic printing presses and combinations thereof, can be used. Preference is given to a set-up time reduction in inking unit washing, the ink inlet in the inking unit and, if necessary, the simultaneous washing of blanket cylinder and of the printing material leading impression cylinder.
  • a transmission gear for example in an offset printing unit with plate cylinder or a flexographic printing unit with forme cylinder, is provided, by which the respective plate or forme cylinder with the main drive and a common gear train (for all the printing substrate realizing cylinder or drums, including blanket cylinder), without additional auxiliary drive, permanent is coupled.
  • the main drive with common gear train ensures the printing operation of all printing units.
  • a transmission gear is arranged at each, alternatively only to individual, plate / forming cylinders of the printing units and designed such that a translation stage (first stage) always translated directly (1: 1) and at least one further translation stage with a deviating from the direct translation Level (second level) translated.
  • the input from the main drive and gear train in the respective printing unit drive is thus transmitted by transmission gear on the respective plate / forme cylinder directly (1: 1) or with a different (1 ⁇ 1), in particular higher (1: ⁇ 1) translation stage.
  • the dampening unit For the preparation of set-up operations, in particular the inking unit washing or the ink inlet, on a printing unit by means of the transfer gear plate / forme cylinder and the inking unit, if necessary, the dampening unit, preferably with significantly higher speeds compared to the washing of the blanket cylinder or the the printing material transporting printing cylinder conventional speeds drivable.
  • the times for cleaning of the inking unit or inking unit and plate / forme cylinder, as needed for cleaning the dampening unit can be significantly reduced.
  • the sheet-fed rotary printing machine shown in Figure 1 comprises at least one printing unit 1, which is formed as an offset printing unit in a known manner by a plate cylinder 6 with associated inking unit 7 and a blanket cylinder 8. If necessary, the plate cylinder 6 is associated with a dampening unit in the direction of rotation in front of the inking unit 7.
  • the sheet-fed rotary printing press further comprises at least one coating unit or flexographic printing unit 2, which by a Form cylinder 10 and a metering system 11, 12 is formed.
  • the metering system 11, 12 comprises in a known manner a screened applicator roll 11 and a chamber doctor blade system 12 for the processing of lacquer, alternatively flexographic ink.
  • the paint / flexographic printing unit 2 is followed by a boom 3 with circulating conveyor system 4 for conveying the sheet-shaped substrate and its subsequent storage on a stack in the conveying direction 5.
  • FIG 2 the drive device for the plate cylinder 6 and the associated inking unit 7 of a printing unit 1 is shown.
  • the plate cylinder 6 is rotatably mounted in each case in an eccentric 20.
  • an eccentric bearing 20 a pin 21 of the plate cylinder 6 is accommodated.
  • the pin 21 is fixedly connected to a leading to the inking unit 7 output gear 16.
  • a bearing 22 is arranged, which receives a freely rotatable drive wheel 13.
  • Adjacent to the freely rotatable drive wheel 13, a transmission gear 18 is arranged, which is operable at least in two gear ratios.
  • the plate cylinder 6 associated, on the pin 21 freely rotatable drive wheel 13 is connected to a upstream drive wheel 14 of the gear train of the main drive of the printing machine in constant mesh.
  • this drive wheel 14 is fixedly connected to the blanket cylinder 8.
  • On the respective drive wheel 14 is from the main drive with gear train and at least one drive motor devisfisbar 15 and the freely rotatable drive wheel 13 via the transmission gear 18 via the pin 21 and the output gear 16, an output 19 on a downstream inking unit 7 derived.
  • each plate cylinder 6 of the printing units 1 is ever a transmission gear 18th arranged and designed such that a translation stage (first stage) always an input drive 15 synchronously (1: 1) translates and at least another translation stage with a deviating from this translation stage (second stage) asynchronous (1 ⁇ 1) translated.
  • Each transmission 18 are associated with two clutches K 1 and K 2 . Both clutches K 1 , K 2 are at least with a control device (not shown) circuitry coupled and can be controlled via appropriate signals.
  • a transmission gear 18 comprises a planetary gear.
  • the planetary gear comprises at least one arranged on a collar 26 of the freely rotatable drive wheel 13 planetary gear 25 and a fixed pin 21 on the sun gear 24 and a stationary with the planetary gears 25 engaged ring gear 23rd
  • the input from the drive 15 (drive wheel 14) fed machine speed is transmitted to the freely rotatable drive wheel 13.
  • the drive wheel 13 is coupled to the ring gear 23.
  • About at least one planetary gear 25 is on the fixed pin 21 on the sun gear 24 and the pin 21 on the output gear 16 of the output 19 in a first gear ratio (1: 1) in the inking unit 7, if necessary, continue to the dampening unit, derived synchronously ,
  • the input from the drive 15 (drive wheel 14) fed machine speed is transmitted to the freely rotatable drive wheel 13.
  • the created by means of the first clutch K 1 connection was disconnected, and the second clutch K 2 is actuated.
  • the ring gear 23 of the transmission gear 18 is fixed to the side frame 17.
  • the ring gear 23 may be displaceable axially parallel to the plate cylinder 6.
  • the input from the main drive and gear train in the respective printing unit 1 drive (input 15) is thus synchronized by means of transmission gear 18 on the respective plate / forme cylinder 6 in a first gear ratio (1: 1) or with a different, especially higher gear ratio (1: ⁇ 1).
  • the inking unit washing (cleaning operation) or the ink inlet to a printing unit 1 is by means of the transfer gear 18 of the plate / forme cylinder 6 and the inking unit 7, if necessary, the dampening unit, with significantly higher speeds compared to the Washing the blanket cylinder 8 or the printing material transporting printing cylinder 9 conventional speeds drivable.
  • a drive 15 with a machine speed of n 2000 -1 supplied to the transmission gear 18 and derived synchronously in the first gear stage via the output 19 in the inking unit 7.
  • the blanket cylinder 8 and / or the printing cylinder 9 thus be cleaned with respect to those in the cleaning operation of the inking unit 7 and at the ink inlet noticeably lower speeds.
