Definitions

  • the invention relates to a doctor blade inking unit for a printing press with a chamber doctor blade delivering ink to an anilox roller, which can be switched between an operating and a parking position by means of an adjusting device and with an ink supply device arranged on the printing machine under the chamber doctor blade, which has an ink pan and an ink pump.
  • the chambered doctor blade is connected to the ink supply device via a hose, one end of which has a releasable hose coupling.
  • a hose one end of which has a releasable hose coupling.
  • the hose between the doctor blade and the feed device is unfavorable.
  • the invention has for its object to provide a doctor blade inking unit which has simply constructed means for separating the chambered doctor blade from the ink supply device.
  • this object is achieved by applying the features of the characterizing part of claim 1.
  • the particular advantage is that a hose and a hose coupling can be dispensed with between the chamber doctor blade and the ink supply device.
  • the 1 has a chambered doctor blade 1 which can be adjusted to an anilox roller 3 by means of an adjusting device 2.
  • the doctor blade 1 has an ink chamber 4, in the top and bottom of which 5 doctor blades 6 can be locked by means of clamping strips.
  • An ink supply channel 7 is attached to the ink chamber 4.
  • the chambered doctor blade 1 has at least one holder 8, which can be fixed on the adjusting device 2.
  • the adjusting device 2 has a crossmember 9, which is rotatably mounted on both ends on the side walls of the printing press.
  • a cold shoulder 10 is connected to the crossmember 9 for each cold 8.
  • the cold 8 of the chambered doctor blade 1 can be attached to the holder projection 10 by means of two bolts 11, the longitudinal axes of which run parallel to the longitudinal axis of the anilox roller 3.
  • a hand lever 12 is connected to an eccentric 13 which is arranged rotatably about the cross member 9. With the eccentric 13, the bolts 11 of the holder 8 can be pressed against the holder projection 10.
  • an ink supply device 14 Arranged below the chamber doctor blade 1 is an ink supply device 14 which has an ink tray 15 in which the ink to be printed is stored and an ink pump 17 connected to a drive 16.
  • the ink supply channel 7 has on the side facing away from the ink chamber 4 an outwardly open ink inlet opening 18 and the ink supply device 14 arranged below it has an ink discharge channel 19 with an outwardly open ink outlet opening 20.
  • Fig. 1 shows the arrangement in the operating position, in which the doctor blade 1 rests on the anilox roller 3.
  • the ink supply channel 7 rests on the ink delivery channel 19, so that they form a continuous line.
  • the underside of the ink supply channel 7 and the top side of the ink delivery channel 19 have flat contact surfaces 21, 22 which in this position run parallel to one another and abut one another.
  • the chamber doctor blade 1 is turned off from the anilox roller 3 by means of a pivoting movement of the crossmember 9 and the ink supply channel 7 from the ink delivery channel 19 of the ink supply device 14 separated.
  • the swivel path of the crossmember 9 is dimensioned such that the ink supply channel 7 comes into contact with the ink discharge channel 19 in the operating position and the ink inlet opening 18 is above the ink outlet opening 20.
  • the clamp of the holder 8 can be released by means of the eccentric 13 by actuating the hand lever 12 of the actuating device 2 and the chamber doctor blade 1 can then be replaced, as shown in FIG. 3.
  • a groove 26, into which a sealing ring 27 is inserted, is machined around a paint outlet opening 23 of a paint delivery channel 24 into a support surface 25.
  • the ink supply channel 7 rests on the sealing ring 7. This improves the sealing effect.
  • ink discharge channel 29 designed as an elastic tube piece into a bore 28 of the ink supply device 14.
  • the ink supply channel 7 then lies in the operating position on the elastic ink delivery channel 29, as shown in FIG. 5.
  • the ink supply channel 7 or both channels 7, 29 could also be made of elastic material. With a good sealing effect, this arrangement can compensate for small tolerances in the travel of the doctor blade 1.
  • An ink delivery channel 30 of the ink feed device 14 has a tube piece 31 which has an end piece 33 which projects out of a support surface 32 of the ink feed device 14 and is tapered there.
  • An ink supply channel 34 is provided with a wall 36 delimiting an ink inlet opening 35, the one has a conical recess 37. In the operating position, the conical recess 37 overlaps the conical end piece 33.
  • this labyrinth seal between the ink supply channel 34 and the ink delivery channel 30 has a gap 38 which is so small on the one hand that no paint escapes and on the other hand is so large that inaccuracies in the combination of the ink supply channel 34 and the ink delivery channel 30 are absorbed can.
  • the chamber doctor blade 1 is turned on and off on the anilox roller 3 by swiveling around the axis of the crossmember 9. All variants of connecting an ink supply channel 7, 34 with an ink delivery channel 19, 24, 29, 30 are closed However, a continuous channel also includes the possibility of providing an actuating device which actuates the turning of the chamber doctor blade 1 on the anilox roller 3 in a straight line.
  • the chamber doctor blade 1 and the ink supply channel 7 can also be brought out of contact with the anilox roller 3 or the ink supply channel 19 by a translational shutdown movement of the crossmember in the direction of arrow a.
  • the direction of arrow a must lie between the directions of lines L1 and L2. If the direction of arrow a is flatter than L1, the ink feed channel 7 hooks on the ink feed device 14, it is steeper than L2, the chambered doctor blade 1 cannot be turned off by the anilox roller 3.
