Definitions

  • the invention relates to a device for inking a roller according to the preamble of claim 1 or 3.
  • DE 44 40 040 A1 discloses an inking unit with an anilox roller and a doctor blade which supplies the anilox roller with ink.
  • an inking unit is known with a doctor blade extending over the entire length of an anilox roller, which has an inlet for the ink in an area near the end and an outlet in the other area near the end.
  • the invention has for its object to provide a device for inking a roller.
  • the ink is supplied to the roller to be inked in a compact, inexpensive and robust manner with high quality.
  • 1 shows a feed by means of two doctor bars; 2 shows a feed by means of a continuous doctor bar;
  • Fig. 4 shows an alternative supply of ink to the doctor bar.
  • a printing unit having a forme cylinder 01 is e.g. B. executed as a double-width printing unit of a printing press and z. B. in addition to application and changing rollers, a roller 02, in particular an anilox roller 02, on which by means of at least one doctor blade 03, z. B. a chamber doctor blade 03, paint can be applied.
  • the doctor blade 03 the ink may also be applied directly to a printing form of a roller 01 designed as a forme cylinder 01, e.g. B. a gravure form, applicable.
  • the printing unit and thus the forme cylinder 01 is in particular double-width, i. H.
  • the printing unit is designed as an offset printing unit, so that the forme cylinder 01 interacts with a transfer cylinder, not shown, which in turn interacts with an impression cylinder via the printing material.
  • the form cylinder 01 has one or more printing forms for planographic printing on its circumference.
  • two doctor blades 03 are arranged side by side over the length of the forme cylinder 01. These doctor blades 03 are on a shaft 04 divided in the first embodiment by means of an adjusting means 06, for. B. adjusting mechanism 06, in particular z. B. a pressure cylinder and a lever mechanism, each by pivoting on or off individually.
  • the adjusting means 06 are preferably designed to be remotely operable. Excess ink drips or runs into the collecting container 07, e.g. B. tubs 07, the bottom of which is sloping in such a way that the color preferably runs into a deepest area. In this area, the ink is returned to the respective doctor blade 03, in particular in an external area, by at least one pump 08 via a feed line 09.
  • Each doctor blade 03 as also described in FIG. 2, can be used in both Color near the end.
  • the feed has a length over the entire length intended for printing, for. B. four printed pages side by side, reaching doctor blade 03, which is arranged on a continuous and pivotable shaft 04.
  • doctor blade 03 which is arranged on a continuous and pivotable shaft 04.
  • two pumps 08 and two feed lines 09 are provided, which supply the ink to the doctor blade 03, in particular in a region near the end.
  • the excess ink can run off in the middle area of the squeegee, in particular through a specially provided outlet.
  • vortexes caused by the flow preferably lie in the non-printing area between two pressure sides.
  • the shape of the doctor blade 03 with a part-circular cross-section also helps to avoid irregularities in the flow and to prevent colors from sticking in corner or edge areas. With the formation of the doctor blade 03 over the entire length, it is possible to roll the roller 02 continuously, i. H. without a streak.
  • the setting is preferably carried out by means of two actuating means 06 assigned to the doctor blade 03, in particular actuating means 06 which can be operated remotely.
  • the or the doctor blade 03 are / is preferably designed in the form of a slotted tube (as a doctor chamber), which advantageously has a working and closing doctor blade in the region of the edges of the slot.
  • the ink can also be supplied with only one pump 08 and two feed lines 09, or possibly a pump 08 and only one feed line 09.
  • the on / off takes place of the squeegee 03 around the shaft 02 near the roller (s) 04.
  • the pivot axis at the level of the tub (s) 07, as is shown in FIG. 4.
  • the ink can then be supplied, for example, in a rigid line that cannot be moved and is not shown here, a rotatable coupling being provided in the region of the pivot axis of the squeegee lever.
  • the doctor blade 03 from FIG. 2 which extends over the entire width, is also applicable to even wider rollers 01; 02, e.g. B. six printed pages wide rollers 01; 02 applicable.
