Definitions

  • the invention relates to a device for positioning a doctor bar against an ink-emitting roller of a web-fed rotary printing press according to the preamble of claim 1.
  • Chamber doctor blades are known, the doctor blade bars of which must be clamped and the doctor blade blades of which must subsequently be placed against an anilox roller. This is technically very complex.
  • the invention has for its object to provide a device for placing a squeegee on an inking roller of a web-fed rotary printing press, which is easy to use and with which the squeegee is easy to attach and can be adjusted with simple means to an inking roller.
  • the following advantages occur in particular: When removing the chamber doctor blade or the doctor blade beam from the holder, a guide is created by turning the tensioning levers horizontally, on which the squeegee bar can be pulled horizontally up to the ball handles, so that the doctor blades can be exchanged without any problems. As a result, little space is required in the machine to be able to handle the doctor bar.
  • the squeegee bar is clamped in a holder and the squeegee bar is positioned with the squeegee blades on an anilox roller in one operation by handling the clamping and adjusting device.
  • the doctor bars 9 to 13 each have an ink supply nozzle 14, which is connected via a flexible line, not shown, to an ink pump, not shown, and an ink reservoir.
  • the ink reservoir also not shown, can be funnel-shaped and at the same time serve as a collecting container for the doctored paint.
  • the doctor bars 9 and 11 are received by a holder 16, and the doctor bars 12 and 13 are received by a holder 17.
  • the brackets 16; 17 are attached to a crossmember 18 which is between the side frames 7; 8 is arranged.
  • Each bracket 16; 17 has four clamping and adjusting devices 19; 21 on, the pairs of the doctor bars 9 to 13 via doctor blade holders 22; 23 are assigned.
  • an anilox roller instead of an anilox roller, another ink-releasing roller can also be used. 2 to 6, there is the clamping and adjusting device 19; 21 each from a body 24 which has two angled, fork-shaped ends 26; 27 has.
  • a shaft 28 is arranged which carries a lever 29 which has a ball handle 31 at one end and an eccentric 32 at its other end.
  • the lever 29 is pivotally mounted through a bore in the eccentric 32.
  • the body 24 is in an axial direction of the doctor blade holder 22; 23 extending fitting screw 33 rotatably mounted in a threaded hole 34.
  • the fitting screw 33 is surrounded by a sleeve 36, the outer diameter of which corresponds to the inner diameter of the blind hole 34.
  • the sleeve 36 has an annular groove 37 running on its circumference, into which the end of a clamping screw 38 engages.
  • the body 24 also has a guide rail 42 running in the axial direction of the fitting screw 23.
  • the doctor bar supports 22; 23 also each have one in the axial direction of the squeegee supports 22; 23 extending surface 43, each two transverse to the axial direction of the Doctor bar supports 22; 23 extending lever strips 44; 46 has.
  • the lever strips 44; 46 have a wedge-shaped cross section and have a different width b 44 at the same height; b 46 on, ie they have a different slope S 44; S 46. The following applies: S 44> S 46.
  • the doctor bar 9 to 13 each consists of a two-part base body 47; 48, each in a doctor blade holder 49; 51 receives a working squeegee 52 or a closing squeegee 53.
  • a striking plate 54 each arranged on the end face of the squeegee bars 9 to 13, closes the chambered squeegee to form a container which is open at the top and can be adjusted to the anilox roller 1 moving in the direction of arrow D.
  • the working doctor blade 52 is placed on the anilox roller 1 at an angle ⁇ to the vertical 56.
  • the two-part base body 47; 48 of the squeegee bars 9 to 13 each have counter strips 50 on their underside; 55 with edges 57; 58, which in the case of movement of the squeegee in the direction of arrow C with the lever bars 44; 46 come into active connection.
  • the base body 48 has a switching recess in the form of a blind hole 59 with a depression or bevel 61 running on one side in the direction of the edge 58.
  • the distance e is the measure of the bias of the plate springs 41 with which the doctor bars 9 to 13 are clamped.
  • the levers 29 are pivoted laterally outwards with the ball handles 31, see also position of the doctor bar 13 in Fig. 1, so that the doctor bar 13 can be moved out on the two guide rails 42 until it strikes the ball handles 31.
  • doctor bar it is also possible to tension the doctor bar by other technical means than disc springs and eccentrics, for example by pneumatic working cylinders.
  • the body 24 is limited in its rotational movement to the horizontal position of the lever 29 by a stop 68.
  • the pushing back of the working squeegee 52 is important in the process of setting the working squeegee against the anilox roller, since the working squeegee 52 due to the different gradients S44; S46 of the lifting bars 44; 46 performs a movement in the direction of arrow C according to FIG. 2.
  • the working doctor blade 52 is pushed in according to the doctor blade wear by the force of the spring 71.
