Definitions

  • the invention relates to a printing press with a plurality of inking units and with a plurality of forme cylinders and impression cylinders according to the preamble of patent claim 1.
  • the impression cylinders are mounted in slides which are guided in radial guides.
  • a lever-toggle lever system is provided for moving these slides, for example in the event of a format change.
  • the object of the invention is to provide a printing machine according to the preamble of claim 1, which can be adjusted in a simple manner after a format change in a simple design.
  • the printing machine according to the invention thereby enables a simple exchange of forme cylinders of different formats that the forme cylinders are mounted together with the inking units on carriages which can be adjusted and disengaged from the associated impression cylinders on approximately tangential to radial to the central wheel and radially outside of it are.
  • the printing machine enables a precise adjustment of the axes of the impression cylinders in a simple manner after a format change, because the respectively aligned arms of the crossing two-armed levers are mounted on the central axis and thus the impression cylinders mounted on these are exactly on the envelope cylinder concentric with the axis of the central wheel swivel. Furthermore, the arms carry the opposing impression cylinders, as it were, in a rocker-like manner, which enables a lighter and simple construction.
  • the arrangement according to the invention can be implemented both in a flexographic printing machine and in a gravure printing machine.
  • FIG. 1 and 2 denote two side stands which are connected to one another via cross members 3 and via a central axis 4.
  • the central axis 4 protrudes outwards from the stand 1, a central gear 6 being freely rotatably mounted on the projecting part 5.
  • This central gear 6 receives its drive via the gear 7, the gear 8, the idler gear 9 and the drive gear 10 of the feed roller 11.
  • two further feed rollers 12 and 13 are provided, the idler gear 9 with the drive wheel of the feed roller 13 also combs.
  • All six format cylinders 14 to 19 are driven by the central wheel 6, the drive for the form cylinder 19 being evident from FIG. 3.
  • This forme cylinder 19, like the other forme cylinders, is mounted between the stands 1 and 2, the forme cylinder axis 20 projecting outwards through both stands 1 and 2 by a certain amount.
  • the axis part protruding from the stand 2 is connected to a cross register adjustment 21 which is known per se and which will not be described in more detail here.
  • the part of the axis 20 which stands out to the left from the stand 1 with reference to FIG. 3 accommodates a longitudinal register adjustment 22 which is known per se and a coupling 23 with a fixed point circuit, so that on the one hand the forme cylinder 19 can be adjusted in the circumferential direction and on the other hand the Forme cylinder 19 can then be held in rotary motion via a continuous-motion motor 24 and via the gearwheels 25 and 26 when the forme cylinder 19 is lifted off the impression cylinder 27 so that the ink does not dry out.
  • the longitudinal register 22 as well as the function of the clutch 23 with fixed-point circuit should not be described in more detail here, because on the one hand they are not part of the invention and on the other hand represent a known prior art.
  • the forme cylinder 19 is driven by the driven wheel 28, the pitch circle diameter of which corresponds to the diameter of the forme cylinder 19.
  • a support press 33-38 is assigned to each impression cylinder 27-32.
  • the two impression cylinders 28 and 31 and the support pressers 34 and 37 are rotatably mounted in the two stands 1 and 2.
  • FIG. 4 shows the forme cylinder 17 with the associated impression cylinder 29 according to FIG. 1 in a simplified representation. 5 the forme cylinder 17 shown in FIG. 4 has now been replaced by a smaller forme cylinder 17.
  • Fig. 4 shows the forme cylinder 17 with the associated impression cylinder 29 according to FIG. 1 in a simplified representation. 5 the forme cylinder 17 shown in FIG. 4 has now been replaced by a smaller forme cylinder 17.
  • the impression cylinders 27 and 30 must be pivoted clockwise, to the same extent as the impression cylinders 29 and 32 must be pivoted counterclockwise.
  • four levers 42-45 are freely rotatably mounted on the central axis 4, two levers, namely the levers 42 and 44 or the levers 43 and 45, forming a pair of levers that oppose one another can be pivoted. So that all levers are as close as possible to the stand 1 or 2, the levers 42 and 44 are bent.
  • the guides 46 and 47 are connected to the stands 1 and 2 and are used to guide threaded nuts 48 and 49.
  • the height of the latter can be adjusted via spindles 50 and 51.
  • the lower ends of the spindles 50 and 51 have sprockets 52 and 53, which are parts of an angular gear, not shown.
  • Both angular gears, not shown are connected to one another by a connecting shaft 54, so that both threaded nuts 48 and 49 can be raised or lowered by the same amount by turning the handwheel 55.
  • the threaded nuts 48 and 49 have pins 56 and 57, which each carry two tabs 58 and 59 or 60 and 61.
  • the free end of the bracket 59 with the straight lever 45, the free end of the bracket 58 with the cranked lever 44, the free end of the bracket 61 with the straight lever 43 and the free end of the bracket 61 with the cranked lever 42 is articulated connected.
  • the levers 44 and 45 or 42 and 43 can consequently be adjusted relative to one another by the same amount. This adjustment serves to be able to bring the impression cylinders 27, 29, 30 and 32 into the correct position according to the forme cylinder used. 2, the impression cylinders and the support pressers are not shown. In FIG. 1, however, it is indicated that, for example, the impression cylinder 29 and the support press 35 are supported at one end on one end of the lever 44.
  • both the impression cylinder 29 and the support press 35 are rotatably mounted at one end of the lever 42 (FIG. 2). From Fig. 2 it can still be seen that the two pins 56 and 57 are connected to one another via a rod 63 for stabilization purposes.
  • Drying blowers 64 are provided between the individual printing units consisting of forme cylinders, impression cylinders and supporting presses.
