Definitions

  • the invention relates to a device for coloring an anilox roller according to the preamble of claim 1.
  • a chambered doctor blade is known from a short inking unit (EP 0 315 091 B1), the ink chamber of which is delimited by a doctor roller, a chamber body with a circular interior, two doctor blades as a working doctor blade with a negative angle of attack or closing doctor blade with a positive angle of attack and two side walls, and a cylindrical, rotatable one and contains in its distance from the anilox roller arranged changeable profile body.
  • the invention has for its object to provide a device for inking an anilox roller according to the preamble of claim 1, which enables avoidance of the disadvantages of the prior art with simple technical means a printable inking of the anilox roller.
  • the invention enables the absence of cross-sectional constrictions in the ink chamber and the avoidance of projections and recesses the extent of this, in conjunction with the special ink supply in the center area of the ink chamber that has the lowest flow velocity, or tangentially or on the end face to the inking roller in its direction of rotation and, if applicable, axial ink discharge, also includes the formation of a laminar flow extending directly to the working squeegee in the form of a roller consisting of ink the maximum ink density in the area in front of the squeegee that is particularly important for inking the anilox roller.
  • Adequate filling of the ink chamber with ongoing replacement of the ink consumption for the printing process is already favored by a slight ink overprint in the ink chamber, since on the other hand, with increasing printing speed, the flow speed and the ink concentration at the periphery of the faster rotating ink roller increase the inking of the anilox roller insensitively.
  • an ink inlet 8 is arranged in the side wall 6, the ink supply being regulated so that a slight overpressure is established in the ink chamber 1.
  • the ink in the ink chamber 1 is rotated as a result of adhesion from the anilox roller 2 as a laminar flow, so that a rotating roller consisting of ink - in other words ink roller 9 - forms, which causes an intensive inking of the anilox roller 2 in front of the working doctor 3, whereby this effect increases automatically with increasing speed of the anilox roller 2.
  • the adjustability of the doctor blade compared to the basic variant shown in FIG. 1 with a common adjustment of both doctor blades via the undivided chamber body 5, it is more favorable to ensure separate adjustability of the doctor blades, for which purpose in a first variant shown in broken lines the chamber body 5 in one opposite its circular interior tangentially displaceably arranged working squeegee holder 10 and a base body 11 which carries the closing squeegee 4 and is divided in three in a further variant shown in dash-dotted lines by a separate closing squeegee holder 12 which is constructed analogously to the working squeegee holder 10.
  • Fig. 2 the solution according to Fig. 1 is varied such that the beginning of the inking zone is determined by a gap S 1 formed between an extended interior of the chamber body 5 and the anilox roller 2, the one against the direction of rotation of the anilox roller 2 one in a slot the basic body 11 I or the separate locking blade holder 12 I arranged locking blade 13 is arranged with a negative angle of attack ⁇ , for the latter according to dash-dotted lines with a corresponding correction of the angle of attack ⁇ I there is also an attachment option on the outside.
  • Fig. 3 shows at a below the anilox roller 2 arranged chamber doctor blade with respect to FIG. 2 is a minimal designed gap S 2, of permitting the outside through a to the longitudinal side of the chamber body 5 II or a separate adjustment of the gap S 2 separated side part 14 inclined color flow surface 15 is limited, which is equipped with a color collecting channel 16 with color return 17.
  • Fig. 5 shows an embodiment for a complete chamber doctor blade using the solution variant of Fig. 1.
  • the base body 11 of the chamber body 5 is releasably attached to a squeegee beam 18 with the aid of a locking device shown in Fig. 6, that in two inward widening recesses 19; 20 in the base body 11, a fitting 21 firmly connected to the squeegee bar and a lever 23 pivotally mounted on a stud bolt 22 fastened in the squeegee bar 18, each positively engaging, the latter being actuated by a pressure medium-operated working cylinder 24 articulated on the squeegee bar 18.
  • one each acts on the working doctor holder 10 or closing doctor holder 12 and acts in its displacement direction and is guided in the doctor bar 18 with a handle 25; 26 adjusting spindle equipped with position indicator for the travel path 27; 28 on.
  • At least one clamping lever 29, which fixes the squeegee holder 10 is pivotably arranged on the squeegee bar 18, enabling the change of the squeegee 3, which is advantageously carried out by one stroke attached to the squeegee bar 18 - As well as a pivoting movement, pressure medium-operated working cylinder 30 is actuated (Fig. 7; 8).
  • the doctor bar 18 (FIG. 5) is pivotally mounted on both sides in a holder 32 connected to the frame via a common tube 31 and has an adjustable stop 33, which limits its pivoting movement against the anilox roller, for a guided in the tube 31, with means for indicating of the travel path equipped adjusting spindle 34 and a pivot bearing 35 for a pressure medium-operated working cylinder 36 articulated on the squeegee beam 18.
  • the doctor bar 18 can avoid damage to the anilox roller 2 and the doctor blades in several stages, with a small pressure on the anilox roller.
  • FIG. 4 shows the ink chamber 1 sealing the chamber body 5 and not shown, covering the doctor blade or side walls 6 resting on the anilox roller on the end face; 7, the side wall 7 being provided axially opposite the ink inlet 8 with a ink outlet 37, so that the ink flow due to a slight excess of ink compared to the ink consumption for the printing process conveniently takes place in the center of the inking roller rotating at a minimal peripheral speed.
  • the surfaces of the doctor blade, the chamber body 5 and the side walls 6; 7 be aerodynamically smooth.
  • Fig. 1 can be used for both directions of rotation of the anilox roller 2, the two doctor blades each swapping their function as working and as a doctor blade (3; 4).
  • the invention is not exclusively tied to a working squeegee with a negative angle of attack, insofar as the formation of the inking roller according to the invention is ensured with a positive angle of attack by appropriate design of the ink chamber, for example based on the area of the closing squeegee of FIG. 2.
  • Fig. 9 the ink supply compared to Fig. 1 is changed so that the chamber body 5 III is equipped with at least one tangentially opening into its interior bore 38, which has 5 III thread on the outside of the chamber body for the connection of a paint line.
  • the bore 38 can also be replaced by a longitudinal slot, which may be connected to a longitudinal bore of the chamber body with a larger cross section for better ink supply.
  • the longitudinal bore is connected to the front of the chamber body 5 III directly or to the longitudinal side thereof via one or more connecting bores to the paint line.
