Definitions

  • the invention relates to an inking unit with a chambered doctor blade, to which ink is fed through an ink line from an ink supply device.
  • the invention has for its object to design an inking unit of this type so that a print requiring only a very small amount of ink can be carried out with little color loss.
  • the chambered doctor blade 1 comprises a chambered doctor blade 1 with a carrier 2 and an ink supply device 3.
  • the chambered doctor blade 1 is connected to the ink supply device 3 via a flexible ink line 4.
  • One end of the paint line is by means of a coupling 5, for example a bayonet coupling or a coupling with a union nut, releasably attached to the carrier 2 of the chamber doctor blade 1.
  • the other end of the paint line 4 can, as in the exemplary embodiment, be permanently connected to the paint feed device or can also be detachably connected to it via a coupling.
  • the chambered doctor blade 1 interacts with an anilox roller 6.
  • a holder 7 is provided for connecting the chamber doctor blade 1.
  • the holder 7 is seated on a crossmember 8, which is rotatably supported at both ends on the side walls of the printing press, and comprises two holders 9 placed on the crossmember at a distance from one another, each of which has two holder approaches 10.
  • Two bolts 11, which are firmly attached to the carrier 2 can be suspended in the holder lugs 10.
  • an eccentric 13 which can be rotated by means of a hand lever 12 is also mounted on the crossmember 8, which acts on the upper side of the carrier 2 and can thereby hold the bolts 11 in firm contact with the holder lugs 10.
  • each anilox roller 6 which includes a support plate 14 and a further cross member 15. Both the support plate 14 and the cross member 15 are connected at both ends to the side walls of the printing press.
  • the support plate 14 serves to hold the ink supply device 3, while a main shaft 16 is mounted on the cross member 15, which drives an output shaft 19 via bevel gears 17, 18.
  • the output shaft 19 is connected via a releasable clutch 20, for example a claw clutch, to a drive shaft 21 for an ink pump 22 of the ink supply device.
  • the ink feed device 3 also has an ink tray 23 in which the ink to be printed is stored.
  • This arrangement is suitable and intended for printing a larger amount of ink.
  • an ink cartridge 24 can be coupled to the chamber doctor blade 1 by means of the releasable coupling 5, as shown in FIG. 2.
  • the ink cartridge 24 has a riser pipe 25 which opens into the cartridge-side coupling half of the coupling 5 and can be supplied with the paint through a pipe 26 to the chambered doctor blade 1.
  • the color cartridge 24 opens another nozzle 27 on which one half of a coupling 28 is seated.
  • the other half of the coupling 28 forms the end of a compressed air supply line 29, which is also at least partially flexible.
  • the compressed air supply line 29 there is also a throttle valve 30, the throttling effect of which can be adjusted by means of a setting wheel 31.
  • the color cartridge 24 is closed at the top by a cover 32 which can be unscrewed into the color cartridge 24 for refilling paint.
  • a web 33 is provided, which extends from the upper side 34, extends over the entire width of the chambered doctor blade 1 and leaves a narrow passage slot open above the lower side 35.
  • an ink collecting trough 36 is provided which, when the ink supply device 3 is removed, can be placed on the crossmember 15 by means of a connecting piece 37, or is attached directly to the doctor blade 1 and support 2.
  • the coupling 5 is released and the ink supply device 3 is removed from the support plate 14. Then the ink drip pan 36 is placed on the cross member 15 and the ink cartridge 24 is connected to the chamber doctor blade 1 by means of the coupling 5. The ink cartridge 24 is then connected to the compressed air supply line 29 via the coupling 28. If the ink cartridge 24 is now pressurized with compressed air, it presses the ink via the riser pipe 25 and the pipe 26 into the chamber doctor blade, via which the anilox roller 6 is inked. From the doctor blade dripping paint is taken up by the ink collecting tray 36.
  • FIG. 4 shows another embodiment of a color cartridge 40.
  • This color cartridge has a nozzle 41 for supplying the compressed air, which opens directly above its bottom 42.
  • a further nozzle 43 is provided for the color derivation.
  • a piston 44 is sealingly guided within the color cartridge, on the upper side of which a compression spring 45 acts, the other end of which is supported on a cover 46 of the cartridge 40.
  • the ink supply is located in the space accommodating the compression spring 45 above the piston 44.
  • the two connecting pieces 41, 43 serve simultaneously to limit the path of the piston 44.
  • the piston 44 presses the paint by compressing the compression spring 45 through the nozzle 43 to the chamber doctor.
  • blowing the compressed air into the chamber doctor blade 1 is excluded.
  • the amount of residual ink that can no longer be used for printing is somewhat larger than in the arrangement according to FIG. 2.
  • the compression spring 45 also causes ink to be sucked back out of the chambered doctor blade when the piston 44 is reset.
