Definitions

  • the invention relates to the construction of flexographic printing inks. These inking units are equipped with a screen roller (2) and a plate roller (3). These two rollers are involved in the ink transport during the printing process.
  • the two aforementioned rollers generally have sleeves that have to be replaced, in particular when changing jobs.
  • the inking units are provided with setting devices
  • pedestals in which the axes of the two rollers (2, 3) involved in the ink transport are mounted are moved.
  • the bearing blocks of a roller can each be attached to slides that slide on suitable guides.
  • Rollers are attached to the machine frame.
  • the side of the inking unit facing the impression cylinder is located, while the motors which move the anilox roller are provided on the side of the two rollers involved in the ink transport facing away from the impression cylinder.
  • the length of the inking unit is large.
  • the object of the present invention is therefore a
  • Ink unit allows.
  • Ink transport rollers (2, 3) are attached to the machine frame.
  • Machine frame is understood here to mean any machine components suitable for fastening the motors.
  • the more compact design of the inking unit according to the invention also leads to a reduction in the vibrations which the rollers experience during the
  • Cliché roller can be moved on different guides.
  • different, vertically spaced guides enable easier positioning of the spindles in the inking unit.
  • a particularly preferred embodiment of the invention is as follows
  • the guides which carry the axis of one of the two rollers involved in the ink transport, are arranged above this roller, - while the guides, which support the axis of the other rollers involved in the ink transport, are attached below this roller.
  • FIG. 2 a section through the inking unit along the line C-C from FIG. 1
  • the figures show an exemplary embodiment of an inking unit 3 according to the invention, in which the setting elements 21, 22, 23, 24, 25 assigned to the printing plate roller 20 are attached below the printing plate roller 20, while the setting elements 11, 12, 13, 14, 15 assigned to the anilox roller 10 are arranged above the same 10.
  • the anilox roller 10 the bearing bracket 15 bearing its axis and the slide 14 on which the bearing bracket 15 is mounted, are suspended from the rail 13.
  • the movement of the slide 14 in the direction outlined by the arrow A takes place in that the motor 11 rotates the spindles 12 which engage through the internal threads 17 present in the bearing block 15.
  • the axis of the plate roller 20 is carried by the bearing block 25 which is attached to the slide 25.
  • the carriage 25 slides in the direction indicated by the arrow B on the rail 23 when the spindle 22 is off the motor 21 is moved.
  • all of the aforementioned elements of the setting devices 11, 12, 13, 14, 15, 21, 22, 23, 24, 25 are carried by a machine frame 2.
  • the counter-pressure roller 1 is shown on the left edge of the figure. In Figure 1, the rollers are in the position required for the printing process on the counter-pressure roller.
  • FIG. 1 illustrates that the free path length of the two spindles 12, 22 between the respective bearings 16, 26 of the spindles 12, 22 and the respective bearing blocks 15, 25 can be set to a minimum in this position in devices according to the invention.
  • FIG. 2 shows a section through the inking unit shown in FIG. 1 along the section line CC. This section describes in particular the function and position of the spindle 12 and guide 13.
  • the internal threads 17 and 27 in which the spindles 12 and 22 are rotated and which therefore have the function of non-rotating nuts can also be seen in this illustration.

Abstract

L'invention concerne un système d'encrage (3) d'une presse flexographique comprenant un cylindre tramé (10) et un cylindre porte-cliché (20). De tels systèmes d'encrage comprennent généralement des dispositifs de réglage (11, 12, 13, 14, 15, 21, 22, 23, 24, 25) servant à régler les positions de ces deux cylindres (10, 20) participant au transfert d'encre par rapport au cylindre de contre-pression (1) et les positions de ces deux cylindres (10, 20) l'un par rapport à l'autre, par déplacement de supports de palier (15, 25) dans lesquels sont logés les axes des deux cylindres (10, 20) participant au transfert d'encre. La force nécessaire au réglage de la position des deux cylindres (10, 20) participant au transfert d'encre est fournie par des moteurs (11, 21) qui font tourner des broches (12, 22) traversant des écrous montés non rotatifs dans les supports de palier (15, 25). L'invention est caractérisée en ce que tous les moteurs (11, 21) sont montés sur le bâti de la machine du côté, orienté vers le cylindre de contre-pression (1), des deux cylindres (10, 20) participant au transfert d'encre.
