Definitions

  • the invention relates to a printing press, preferably a flexographic printing press an impression cylinder mounted in a printing press frame, which with a Drive is provided, and with at least one printing unit, which consists of a driven, on the impression cylinder adjustable pressure roller and from one the print roller is adjustable inking or anilox roller, which with a Flush inking unit interacts, with the impression cylinder, the printing and anilox roller each have coaxial gears to drive them and the anilox roller is provided with a special continuous drive.
  • a flexographic printing machine of this type is for example from DE-PS 34 37 216 known. 5 of the drawing, the drive of the Impression cylinder and the drive of the printing roller and the anilox roller only one Printing unit of the known printing machine described.
  • the shaft journals of the impression cylinder 3 stored which is only indicated by the dashed center line are.
  • the central wheel 4 wedged On the right shaft journal of the counter-pressure cylinder 3 is the central wheel 4 wedged.
  • the central wheel 4 wid from the main drive motor 5, which is is an electric motor, via the drive pinion 6 and the intermediate gears 7 to 10, which form the corresponding gear stages, driven.
  • the gears 8 and 9 are wedged onto a shaft 11 indicated by a broken line, which is also shown in FIG Printing machine frame is stored.
  • the printing roller 12 and the anilox roller 13 are mounted in bearing blocks of ships which are displaceably guided on consoles of the printing machine frame, as has been described in DE-PS 34 37 216.
  • the pressure roller gear 14 and the anilox roller gear 15 are placed on the right, which pass through the bearing blocks of the printing roller 12 and the anilox roller 13, which are also only indicated by dashed lines, the anilox roller gear 15 being mounted on the anilox roller shaft via a freewheel 16.
  • the pressure roller and anilox roller slides lead to a long stroke movement for the exchange of a printing roller and to move into the Push-down position "only a short-stroke movement, in which the cylinders and rollers are moved away from each other, but the teeth are still loosely engaged with each other.
  • the anilox roller 13 runs in the print-down position with a lower one Speed further than in printing operation to with shorter printing interruptions prevent the ink from drying or drying.
  • This continuous drive consists of the servo motor 17, which via the gears 18, 19th existing gear stage and the freewheel 20, the anilox roller 13 on the left Drives shaft journals.
  • This continuous drive is possible because of the anilox roller 13 because of the right freewheel 16 even when the anilox roller gear 15 is blocked can be turned in one direction.
  • the continuous drive hinders normal Printing operation the drive of the anilox roller 13 via the central wheel 4 and the printing roller gear 14 not because the drive gear 19 via a freewheel 20 is mounted on the left shaft journal of the anilox roller 13.
  • This flushing inking unit consists of a doctor blade carrier 21 which can be adjusted to the anilox roller 13 and which consists of a profiled strip consists.
  • the bar of the doctor blade carrier 21 is the interior of the ink chamber forming gutter.
  • a channel opens into this channel in the middle the ink supply hole 22.
  • the ink draining holes 23 and 24 In the lower end areas of the gutter the ink draining holes 23 and 24.
  • the end faces of the Channel edges of the doctor blade holder are chamfered in opposite directions. Doctor knives are attached to these end faces, which scrape or paint the anilox roller 13 are adjustable.
  • Are on the sides of the doctor blade holder Seals arranged that the ink chamber interior opposite the anilox roller 13 seal. Doctor devices of this type are, for example, from the German Patent applications 195 16 223.3 and 195 16 224.2 are known, to which closer Description of the doctor device is referred to.
  • DE-PS 34 37 216 has been described that it bie printing machines and especially flexographic printing presses is a particular problem after changing the Align the forme cylinders to match each other.
  • DE-OS 34 32 572 also shows a printing press for the purpose of moving on, in which both the impression cylinder and the printing and anilox roller one each printing unit are driven by separate servo motors. But since that Control engineering effort for the interaction of all engines with each other extremely high and is currently not economically viable, such Press drives have not yet been implemented in practice.
  • the object of the invention is to provide a printing machine which is specified at the outset To create a way in which the anilox roller both for the purpose of moving on with a low running speed compared to the operating speed as well Purpose of rinsing the doctor device against the operating speed reversible drive speed increased and also a simple fit Alignment of the printing cylinders after changing them is possible.
  • this overall task is the beginning of a printing press specified type solved in that only the printing roller gear by parallel displacement can be coupled with the impression cylinder gear for printing and that the anilox roller with its own controllable, speed variable and reversible Provide the drive and to align the printing rollers correctly a format change by a gear with the pressure roller gear can be coupled.
  • the printing press during of the printing operation, only the printing rollers are driven by the central wheel, with which the pressure roller gears comb.
  • the anilox roller is also used in printing driven by the anilox roller drive, the speed of the anilox roller can be controlled via a computer.
  • the drive motor for the anilox roller drive exists expediently from a stepper motor.
  • the anilox roller can thus be run at the same peripheral speed how to drive the platen roller.
  • the anilox roller with higher or lower peripheral speed during printing than that of the printing roller to drive, so that thereby the ink application can be controlled on the printing roller.
  • the anilox roller can be reversed with the higher ones Drive speeds, for example at a higher speed than that during printing.
  • a particular advantage of this embodiment of the invention is that the anilox roller drives are used after changing the printing cylinders can match the printing cylinders of the multiple printing units to each other align.
  • the anilox roller drives turn the individual from this basic position Printing cylinders in positions in which they are aligned to each other are.
  • the individual stepper motors of the anilox roller drives are controlled through a computer in which the basic position and the individual angles of rotation to align the printing rollers in their correct positions are.
  • a printing press the preamble of claim 1 provided that the anilox roller in turn with its own controllable, speed-variable and reversible drive is provided and that the pressure roller gear only with the anilox roller gear can be coupled and the anilox roller gear by a switchable clutch from the anilox roller is detachable.
  • the printing roller in printing operation no longer from the one driving the impression cylinder Central wheel driven, but via the anilox roller drive.
  • the anilox roller drive one of the peripheral speed the speed of the impression cylinder is given, so that due to the relative speed that can be achieved, settlement errors the web to be printed can be compensated.
  • a slower one Rotation of the printing cylinder can stretch the printed image in the circumferential direction and be compressed by a higher speed.
  • the right-hand shaft journal of the anilox roller 13 is provided with a toothed wheel 41, that after decoupling the gears 4 and 14 and moving together accordingly bzuuw. Aligning the printing roller 12 and the anilox roller 13 only bring into engagement with the teeth of the gear 41 by axial displacement lets so that the anilox roller drive of the forme cylinder 12 after a change for presetting the registers to the printing rollers of the other printing units can be aligned.
  • the pressure roller gear 14 is moved axially brought out of engagement with the gear 41 of the anilox roller and the printing roller is moved into its printing position on the impression cylinder 3, so that the toothings 4, 14 come into engagement with one another in the correct position.
  • FIGS. 1 and 2 is a second embodiment of the drive according to the invention It can be seen that the embodiment of FIGS. 1 and 2 in differs essentially only in that even during printing the drive of the printing roller 12 via the servo motor 50 for driving the anilox roller 13 takes place.
  • the central wheel 51 is therefore of a correspondingly smaller diameter executed so that it is no longer in engagement with the printing roller gear during printing 14 is coming.
  • the servomotors for the anilox roller drives are selected such that they in their performance meet and meet the requirements to be met by them the machine control for the angular adjustment of the pressure rollers can be.
  • the invention is above only on a printing unit of a flexographic printing machine have been described. The same applies to the other printing units Multicolour printing machines.
