Definitions

  • the invention relates to a doctor bar of a chamber doctor blade according to the preamble of claim 1 and a method for its use according to claim 6.
  • the doctor blades are inserted into a slot in a chambered doctor blade to ensure quick interchangeability.
  • DE-OS 25 38 908 it is known to resiliently arrange a rapidly wearing doctor blade for a gravure printing machine.
  • the squeegee is placed almost perpendicular to the jacket of the cylinder to be inked.
  • EP 04 53 910 A1 shows a generic doctor bar for a short inking unit of a web-fed rotary printing press. This doctor bar has two doctor blades held in a clamping device which can be set against a screen roller with a negative angle of attack.
  • US 27 04 026 A describes a doctor bar of a gravure printing machine.
  • the squeegee can be adjusted to a forme cylinder by means of spring force.
  • DE 2 33 430 C discloses a doctor blade device for rotogravure printing presses.
  • a plurality of squeegee blades can be simultaneously spring-loaded on a forme cylinder as a storage magazine and adjustable with respect to the forme cylinder by means of a spindle.
  • the invention has for its object a doctor bar of a chamber doctor for a short inking unit of a web-fed rotary printing press, the doctor blades, in particular the working doctor, in a negative Angle of attack of the working squeegee with the anilox roller are arranged, with which bending of the working edge of the squeegee blades is avoided and the service life of the squeegee blades is increased.
  • the resilient positioning of the working squeegee on a straight line which runs in the direction of the transverse axis of the working squeegee prevents the squeegee from bending due to the pretension when it is placed against the anilox roller.
  • Fig. 1 shows a partial view of a doctor bar 1 from the front.
  • the doctor bar 1 carries a working doctor 2, which is arranged between a doctor holder 3 and a doctor guide 4, see FIGS. 2 and 3.
  • the doctor holder is attached to the doctor guide 4 by means of screws 6.
  • the doctor bar 1 is designed symmetrically, which is expressed by the center line 7 shown in FIG. 1.
  • On the squeegee holder 3, an abutment 8 is fixedly arranged, above which there is an elongated hole 9.
  • the doctor blade guide 4 is seated in a receptacle 11 of the base body 12.
  • a further base body 13 carries the closing doctor blade 14, which are fastened by means of screws 17 via a doctor blade holder 16.
  • the squeegee 2; 14 are interchangeable and touch the surface of an anilox roller 18 at a negative angle of about 40 °.
  • the anilox roller 18 moves in the direction of arrow A.
  • the doctor bar 1 has an actuating element, designated overall by 19.
  • the actuating element 19 consists of a pin 21 which is connected at one end to an eccentric disc 22.
  • the eccentric disc 22 has a handle 23.
  • the free end of the pin 21 protrudes through the Elongated hole 9 of the doctor guide 4 through into a bore 24 of the base body 12.
  • the pin 21 is rotatably mounted there.
  • the doctor guide of the working doctor 2 designated overall by 4, is shown.
  • the squeegee guide 4 consists of a bar 26 which extends in the axial direction of the anilox roller 18 and has two bores 27, each of which has a pressure piece 28 and an adjusting screw 29 at its ends.
  • a compression spring 31 is arranged between the pressure piece 28 and the set screw 29, so that the pressure piece 28 is spring-mounted and thus the distance b of the doctor guide 4 according to FIG. 2 can be increased as a result of the doctor wear.
  • the actuating element 19 and the bore 27 for the suspension are shown only once. Due to the symmetry of the doctor bar 1, symbolized by the center line 7, a total of two actuating elements 19, two abutments 8 and two bores 27 are provided for receiving the suspension per doctor bar 1.
  • the method of operation is as follows:
  • the doctor bar 1 can by means not shown, for. B. by guides and hydraulic cylinders in the vertical direction according to the direction of arrow C.
  • the squeegee bar 1 is moved vertically upward in the direction of arrow C by the means, not shown, until the closing squeegee 14 has contact with the surface of the working edge Anilox roller 18.
  • the working squeegee 2 is in the locked position shown in FIG. 5, ie there is a distance d between the anilox roller 18 and the working edge of the working squeegee 2.
  • the eccentric disc 22 is in operative connection with the abutment 8, so that the Distance b is minimized according to FIG. 3.
