Description

The invention relates to a drive arrangement for a Farbduktor a sheet processing machine, a work for a sheet processing machine and a method for operating the drive assembly according to the preamble of claim 1, 7 and 8 respectively.

A sheet processing machine usually has a main drive for driving at least the sheet transport serving cylinders or rollers using a gear train on. In addition, individual drives are used for directly driving individual cylinders, so that these cylinders can be driven independently of the main drive. Thus, it is known to drive the cylinders of a printing unit, an inking unit and a dampening unit with one or more independent of the main drive individual drives.

A printing unit is a part of the sheet processing machine in which the printing of a printing material or a substrate between a forme cylinder and a transfer cylinder takes place. Printing ink is applied in an inking unit via a clocked ink lifter from a Farbduktor on Verreibwalzen or distributor rollers. A dampening unit moistens the part of the forme cylinder that is not coated with ink to produce a uniform print result without blurring.

The ink ductor, called a short ductor, is a roller in the inking unit of the printing unit, from which the ink is passed on from an ink fountain to the distribution rollers with a color lifter. A Farbduktorantrieb drives the Farbduktor via a shaft.

From the DE 2 165 185 A is a drive for a printing unit of an offset web-fed rotary printing machine with four each consisting of a plate and a blanket cylinder printing units known. When working as a satellite movement, the blanket cylinders can be adjusted in pairs to a common impression cylinder or when working as a rubber-rubber printing unit.

The DE 1 287 089 A teaches an inking unit drive for web-fed rotary printing presses with a drive train derived from the main drive and an electric motor which can be switched into the inking unit drive. The electric motor is arranged between the skin drive and a control gear for the ductor. The electric motor is connected to a clutch directly to the main drive. In addition, the electric motor is firmly connected to a control gear of the ductor.

In the case of a switchable design, this allows several modes of operation for optimizing the wet-liquid supply.

3 shows a schematic representation of a first preferred embodiment of the executed printing unit 05 with a drive arrangement 36 , Shown here are the form cylinder 09 as well as the inking unit 22 with the inking roller 25 , the color lifter 27 and the ink ductor 24 , To drive a Farbduktorantrieb serve 37 and a main drive 38 each comprising an electric motor M.

The transmission of torque from the main drive 38 on the form cylinder 09 will be over two waves 40 . 41 realized that via a first gearbox 43 are coupled. The first transmission 43 is preferably a gear transmission. Through a second gear 44 , which is designed as a deflection gear, the torque from the shaft 41 on another wave 46 and on a planetary gear 47 transfer. The planetary gearbox 47 conducts the torque over a shaft 49 on the inking roller 25 of the inking unit 22 , The planetary gearbox 47 is about a wave 50 with a third gear 52 connected, of which in turn another wave 51 to the ink ductor 24 going on.

To drive, ie to the timing of the color lifter 27 there is a wave 54 over a fourth gear 55 with the from the epicyclic gearbox 47 outgoing wave 49 engaged. The control of the timing of the color lifter 27 done by one on the other wave 54 seated cam 56 showing the torque of this further shaft 54 as a clocked up and down movement on a drive shaft 58 the color lifter 27 transfers.

In a first operating state drives the ink duct drive 37 over the third gear 52 and the wave 51 the ink ductor 24 at.

In a second operating state, using the third gearbox 52 and the wave 50 between the third gear 52 and the epicyclic gearbox 47 the torque from the ink duct drive 37 be used to further drive the drive assembly 36 to realize.

In a drive variant drives the ink duct drive 37 in addition to the ink ductor 24 the form cylinder 09 and the inking roller 25 of the inking unit 22 including the color lifter 27 when printing on. The main drive 38 does not drive according to this drive variant, including a first clutch 59 on the wave 40 is set in a disengaged state. In a modified drive variant decouples a second clutch 60 the torque transmission through the shaft 51 and thus the ink duct drive 37 from the ink ductor 24 For example, during a roller wash.

When changing the printing plate on the forme cylinder 09 This can be done with the help of the ink duct drive 37 or by using the main drive 38 are driven. If the drive via the ink duct drive 37 so is next to the first clutch 59 and the second clutch 60 also a third clutch 62 in the wave 49 disengaged. The third clutch 62 inhibits together with a first brake 63 on the wave 49 the torque transmission between the planetary gear 47 and the inking unit 22 , Generates the main drive 38 a torque, which is the pressure plate change on the forme cylinder 09 is necessary, so is the first clutch 59 in the wave 40 engaged while a fourth clutch 64 in the wave 46 is disengaged and together with a second brake 66 on the wave 46 the torque transmission between the second gear 44 and the epicyclic gearbox 47 interrupts. In this operating variant, the inking unit 22 for example, using the Farbduktorantriebes 37 via the engaged third clutch 62 are driven. Is the second clutch 60 between the ink duct drive 37 and the ink ductor 24 disengaged, leaving only the inking unit 22 with the ink duct drive 37 is engaged, so in this operating state, the inking unit speeds corresponding to different profiles, for example, for roller washing or Farbeinlaufen applicable. For example, different peripheral speeds and / or speeds of the inking unit 22 and the forme cylinder 09 be realized, if also at the same time the first clutch 59 in the wave 40 engaged and the fourth clutch 64 in the wave 46 disengaged. So one can on the form cylinder 09 located pressure plate (not shown) smoothed or ironed when the inking unit roller 25 of the inking unit 22 at a slightly different peripheral speed and / or speed than the forme cylinder 09 is driven. The inking roller 25 transmits by friction a tensile stress on the plate, so that the pressure plate on the forme cylinder 09 is tense.

4 shows a schematic representation of a second preferred embodiment of the running printing unit 05 with the drive assembly 36 , Shown again are the form cylinder 09 as well as the inking unit 22 with the inking roller 25 , the color lifter 27 and the ink ductor 24 , To drive the Farbduktorantrieb serve 37 and the main drive 38 each comprising an electric motor M. Also shown is the dampening unit 34 with a separate dampening unit drive 68 , in particular electric motor M. During the printing and also during the roller washing it is possible according to this embodiment, the dampening unit 34 over the dampening unit drive 68 drive. The dampening must be done during a printing operation.

The drive arrangement 36 also has a straight toothed gear stage 69 , in which a first gear 71 rotatably on the between the ink duct drive 37 and the ink ductor 24 arranged wave 51 sitting. A second gear 72 and a third gear 73 sit rotatably mounted on the inking roller 25 of the inking unit 22 driving shaft 49 , The first gear 71 the second gear meshes 72 , The form cylinder 09 gets through the main drive 38 driven. On the wave 41 a non-rotatably connected with this fourth gear connected 76 which is from a fifth gear 77 , which rotatably on the shaft 40 of the main drive 38 sits, is driven by combing.

The drive of the inking roller 25 over the ink duct drive 37 or over the main drive 38 is done by switching the on the shaft 49 arranged third clutch 62 ,

The positions of the second clutch represented by solid lines 60 and third clutch 62 lead to the drive of the inking roller 25 through the ink duct drive 37 ,

This switching position is preferably to choose when washing rolls. In the positions of the second clutch shown in dashed lines 60 and third clutch 62 the drive of the inking unit roller takes place 25 over the main drive 38 during the ink duct drive 37 the ink ductor 24 drives. In the position of the third clutch represented by solid lines 62 and in the position of the second clutch shown in dashed lines 60 drives the ink duct drive 37 the ink ductor 24 and the inking roller 25 at. The illustrated dampening unit 34 is about another wave 79 separately through the fencing drive 68 driven.
