Definitions

  • the invention relates to a device for clamping and hiring a squeegee to an inking roller, eg. B. anilox roller, a web-fed rotary printing press according to the preamble of claim 1.
  • an inking roller eg. B. anilox roller
  • a web-fed rotary printing press according to the preamble of claim 1.
  • Chamber doctor blades are known (see e.g. EP-A-0359959), 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 clamping and placing a doctor bar on an ink-donating roller, with which the doctor bar is easy to handle, clamp and adjust to the ink-donating roller.
  • the following advantages occur in particular:
  • a guide is created by rotating the tensioning lever into the horizontal, on which the Squeegee bar in a horizontal direction until ball handles can be pulled.
  • 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.
  • Another advantage is that the squeegee is placed in the mounting position on the guide rails of the clamping device.
  • the levers with the ball grips are parallel to the squeegee beam mounts.
  • the ball handles of the levers serve as a stop for the longitudinal edge of the squeegee bar, so that the squeegee bar cannot slide on independently.
  • 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 fastened on a cross member 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 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.
  • clamping and adjusting device 19 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 outside diameter of which corresponds to the inside diameter of the blind hole 34.
  • the sleeve 36 has one on its circumference extending annular groove 37 in which the end of a clamping screw 38 engages.
  • Disc springs 41 are arranged between the head 39 of the fitting screw 33 and the end face of the sleeve 36.
  • the body 24 also has a guide rail 42 running in the axial direction of the fitting screw 23.
  • the doctor blade holders 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 squeegee holders 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, d. H. 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 an open-topped container which can be adjusted to the anilox roller 1 moving in the direction of arrow D.
  • the working squeegee 52 is placed on the anilox roller 1 at an angle ⁇ to the vertical 56.
  • the two-part base body 47; 48 of the doctor 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.
  • a pressure piece 63 which can be actuated against the force of a spring 62 in the axial direction of the doctor bar holder 23.
  • This pressure piece 63 gets actuation of the doctor bar according to FIG. 2 in the direction of arrow C contact with a limit switch 64, which is connected via contact lugs 66 and connecting cable 67 to an electrical control, not shown, which switches the ink pump on when the pressure piece 63 is in the 4 is in the position.
  • the distance e is the measure of the preload 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 the position of the doctor blade 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.
  • the distance f between the edges 57; 58 of the counter strips 50; 3 is greater than the distance g between the lever strips 44; 46.
  • the upper sides 69; 70 of the lever bars 44; 46 in operative connection with the flat surfaces of the counter strips 50; 55.
  • the working doctor blade 52 can be pushed back against the force of a spring 71 according to FIGS. 2 and 4.
  • 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 squeegee 52 is pushed in according to the squeegee wear by the force of the spring 71.
