Definitions

  • the invention relates to a flexographic printing machine with an impression cylinder mounted in a printing press frame for a plurality of printing units, which consist of printing rollers and associated inking units, preferably anilox rollers with ink chamber doctor blades, and are arranged on separate consoles in such a way that each printing roller and each inking roller are relative on each console Move towards each other and let both of them work together on the impression cylinder, the impression roller and the printing and inking unit rollers being provided with drives.
  • printing units consist of printing rollers and associated inking units, preferably anilox rollers with ink chamber doctor blades, and are arranged on separate consoles in such a way that each printing roller and each inking roller are relative on each console Move towards each other and let both of them work together on the impression cylinder, the impression roller and the printing and inking unit rollers being provided with drives.
  • Flexographic printing machines of this type are known for example from DE 29 41 521 A1, DE 34 37 216 C2, DE 37 42 129 A1 and DE 40 01 735 A1.
  • the consoles carrying the inking units and printing rollers are firmly connected to the machine frame, so that the possible printing lengths basically depend on the spacing of the consoles or the spacing of the printing rollers from one another, measured over the circumference of the counter-pressure roller, and larger printing lengths are only possible are when individual printing units are taken out of operation.
  • the object of the invention is to provide a flexographic printing machine of the type specified at the outset, with which any desired printing lengths can be set.
  • this object is achieved in a flexographic printing machine of the type specified at the outset in that the brackets are held displaceably in the guides of the printing press frame or in guides connected to them in such a manner and can be fixed in desired positions that the printing roller axes are displaced when moving to the axis of the impression cylinder concentric enveloping cylinders.
  • the flexographic printing machine according to the invention can be adjusted in a simple manner to any desired printing formats by moving the consoles of the printing printing units to a corresponding distance relative to one another or by special drives and fixing them in the positions thus set.
  • the printing units can, for example, be distributed symmetrically to the vertical center plane of the counter-pressure roller.
  • the central counter-pressure cylinder can be used for maximum printing lengths through the appropriate setup and setting of the printing units.
  • Printing units inserted into the guides and not required can be moved with their consoles to a waiting position or parking position in which they do not print.
  • the drives for the printing rollers and inking rollers can be derived centrally from the central gearwheel connected to the impression roller. It is more expedient, however, to provide separate drives for the impression cylinder as well as for the printing and inking unit rollers, which make it easier to maintain the register enable.
  • Such multi-motor drives are known for example from DE 34 32 572 A1.
  • brackets can be inserted into and removed from the guides. In this way, it is easily possible to retrofit or remove inking units or printing units. This configuration allows the printing machine to be provided with the desired number of printing units at the operator's choice.
  • FIG. 1 shows a schematic representation of a flexographic printing press which consists of a machine frame, in the side parts 1 of which a counter-pressure cylinder 2, which is not provided with a drive, is mounted in the usual manner.
  • the side parts 1 of the printing press frame are provided on their inner sides with guides 3 for the printing unit consoles 4.
  • the guides can be of any design and consist, for example, of rings concentric to the axis of the impression cylinder, which are fastened to the inner sides of the side parts 1 of the printing press frame. These rings 3 can be surrounded by guide shoes 5, which are attached to the side walls of the printing unit consoles 4.
  • the guides can also consist of ball bushings.
  • 4 shafts 6 are mounted in the side walls of the inking unit consoles, which carry pinions 7 on their shaft journals projecting beyond the side walls, which mesh with toothings 8 which are attached to the side parts 1 of the printing press frame.
  • One of the side walls of the inking unit consoles 4 is connected to a support 9 to which a geared motor 10 is flanged, which drives the pinion shaft 6, so that each of the printing units 4 can be moved on a concentric circle to the axis of the impression cylinder by a corresponding motor control.
  • brackets 4 On each of the brackets 4 in the usual way movable bearing blocks are arranged, which support the printing unit rollers 12 and the inking or anilox rollers 13.
  • the inking units or ink chamber doctor blades are not shown.
  • the printing unit consoles 4 which can be moved on the guides 3 in guide shoes 5 can preferably be moved into a position in which they pull out and insert like a drawer from the printing machine frame to let.
  • the station for inserting and removing the printing unit consoles 4 is preferably located on the upper side of the printing machine frame. In this area, the guide, which rotates concentrically with the counter-pressure roller, can be interrupted in such a way that the printing unit consoles can be pushed into the printing press frame and threaded into the guides.
  • the printing group consoles 4 are displaceable on their guides, which are basically designed in the same way as the guides according to FIGS. 1 to 3, by hand or by external lifting and / or transport means. 1 to 3, the printing unit consoles can be fixed in the desired positions by the geared motors 10, according to the exemplary embodiment according to FIGS. 4 to 6 the printing unit consoles are fixed in the desired positions, for example by bolts 20.
  • the side parts 1 of the printing press frame are provided with holes 21 on a circular line concentric with the axis of the impression cylinder 2, which in the positions to be fixed are aligned with holes in the side walls of the printing unit consoles 4.
  • the printing unit consoles are then fixed in the desired positions by inserting the bolts 20, which are then secured in the usual manner.
