Definitions

  • the invention relates to a printing press, preferably a flexographic printing press, with at least one impression cylinder and several Printing units in which the bearings of the printing cylinders and the inking units with the inking rollers of the individual Printing units on guides of the printing press frame radially or can be moved almost radially to the impression cylinder and at the drive of the pressure cylinder from a central drive, preferably a central wheel is derived.
  • the jackets of the impression cylinder and the impression cylinder revolve at the same peripheral speed. This condition is easy to accomplish when the diameter of the impression cylinder the diameters of the pitch circles of the associated drive gears correspond. Should be different with impression cylinders Diameters are printed, the diameters may only be in Change jumps that correspond to the tooth pitch of the drive gears, because otherwise the cylinder jackets will run in sync is not guaranteed with the impression cylinder jacket. The change in the diameter of the cylinder jackets only in Cracks in the tooth pitch of the associated drive gears are required however, restrictions on the design of the pressure rollers as well of the clichés to be attached to these, which are often undesirable are.
  • the object of the invention is therefore a printing machine of the beginning specified type to create, in which the diameter of the Printing cylinder regardless of the tooth pitch of the associated drive gears can be chosen.
  • this object is achieved in that for Printing cylinder provided a separate common controllable drive is and that between the drive gear and the driven Bearing journals of each pressure roller have a parallelogram coupling is arranged.
  • Parallelogram couplings are machine elements which have an axis offset from each other coupled by this Compensate for parallel waves over an offset distance. Such parallelogram couplings are also known as Schmidt couplings known.
  • the printing press according to the invention can be used in the usual way set up with pressure cylinders of different diameters, whereby however, each impression cylinder is connected to only one drive gear needs to become, without therefore meeting the condition is that the pressure cylinder diameter only changes the pitch of the teeth of the drive gear may change.
  • the Printing machine according to the invention resemble the parallelogram couplings each the axis offset between that of the drive gear driven shaft and the pressure roller coupled with this out. Since the axis offset to be compensated for is only slight, a parallelogram coupling can be used without any problems.
  • the peripheral speed of the printing cylinder can be determined by the separate common controllable drive in a simple manner accurate adjust the peripheral speed of the impression cylinder.
  • the controllable drive is usually an electric motor.
  • the drive gearwheels of the pressure cylinders are preferably driven by a common central wheel. It would be natural also possible through the drive gears of the impression cylinder to drive an endless chain or an endless timing belt. This could also be done via individually controlled electric motors happen.
  • the impression cylinder with a separate one is also expedient Provide drive. This can also be from a central wheel exist with which a driven by a controllable motor Drive pinion combs.
  • impression cylinders for the individual impression cylinders can be by a gear or also from a common chain or a common toothed belt be driven.
  • the inking rollers with a separate controllable drive are provided.
  • This drive can consist of an endless chain or an endless toothed belt.
  • the runs Timing belt or chain on one side of each inking roller via frame-fixed deflection wheels, one of which is radially inward and one radially outward of each inking roller and via a deflection wheel mounted on each inking unit frame looped over each drive wheel of each inking roller, with the chain or timing belt between the outer frame-fixed deflection wheel and the drive wheel and between the deflection wheel mounted on the inking unit frame and the inner one frame-fixed deflection wheel are parallel to each other.
  • the inking rollers of the printing units are expediently both Sides of the printing press each by separate endless chains or toothed belt driven by wheels fixed to the frame are driven by a common running through this Chain or a common toothed belt are driven.
  • the drives of the impression cylinder and the ink application or Anilox rollers are controlled by controlled electric motors.
  • the flexographic printing machine is basically of a known type, which for example from DE 43 08 492 A1 and the stand in this the publications mentioned in the art are known to is referred to for further explanation.
  • the flexographic printing machine shown in the drawing has one from the side parts 1, 2 existing frame in which for all printing units a common impression cylinder 1 stored is.
  • the printing machine frame is on both sides, for example provided consoles apparent from DE 29 41 521 A1, the bearing with guides for the pressure cylinder blocks 4 Carriages are provided, these printing cylinder slides in turn can be provided with guides for inking units 5, if both of the same guides cannot be moved. While in the embodiment described in DE 29 41 521 A1 the inking units from immersion rollers and Ink rollers exist, the one shown in the drawing Flexo printing machine only one anilox roller for each inking unit 7, which in a known and therefore not described manner an ink chamber doctor blade is provided.
  • Shaft journal 12 is freely rotatable and immovable in the axial direction the central wheel 13 is supported by a drive pinion 14 is driven by a controllable motor 15.
  • the the Side walls 1 projecting shaft journal flying in these stored pressure cylinder 6 are by parallelogram clutches 16 with shafts mounted in the uprights or partition walls 17 18 coupled, which penetrate the partition walls 17 Wear ends of drive gears 19.
  • the parallelogram coupling 16 equalizes an axis offset between the drive gears 19th bearing shafts 18 and the shaft journal 20 or of these driven pressure cylinders 6 from.
  • the anilox rollers 7 stored in the inking units 5 are driven by endless belts via the anilox roller gears 33.
  • the anilox rollers 7 on the left side of the flexographic printing machine are of the endless toothed belt 31 and the anilox rollers right side driven by the endless toothed belt 32.
  • the endless toothed belt 31 runs over the deflection wheels fixed to the frame 21, 22, 23, 24 and 34 and the right endless toothed belt 32 about the frame-fixed deflection wheels 25, 26, 27, 28 and 35.
  • the endless toothed belts 31 and 32 are driven by the deflection wheels 22 and 26, which are made correspondingly wide, by a endless toothed belt 38 driven to drive over that driven by the anilox roller motor 40 via a gear stage Gear 39 runs.
  • the endless toothed belt 38 runs in the manner shown continues on frame-fixed deflection wheels 42, 43 and 44 as well as via deflection wheels that can be freely rotated and mounted coaxially to the deflection wheels 21, 25, 34 and 35 are. Furthermore, the drive of the two endless belts runs 31, 32 serving endless belts 38 over the frame-fixed deflection wheel 45.
  • the dreams 46, 47 of the endless toothed belts 31, 32 that between the frame-fixed deflection wheels 24, 28 and the drive gears 33 of the anilox rollers 7 and those mounted on the inking units Deflection wheels 29, 30 and the inner frame-fixed deflection wheels 22, 26 are parallel to each other, so that the endless Toothed belt 31, 32 in a process of the inking blocks experienced no change in length.
