Definitions
- the invention relates to a device for inking and metering a roller of a rotary printing press according to the preamble of claim 1 and an associated device.
- EP 06 63 293 A1 discloses a device for inking an anilox roller, in which printing ink rotates in a fully filled ink chamber with a circular cross section about a longitudinal axis running to the anilox roller.
- a negative squeegee and a positive squeegee are provided.
- the disadvantage of this device is that a preformed ink chamber is required, into which printing ink is pumped. This creates air bubbles, which lead to inking fluctuations on the roller. Furthermore, when the printing ink is fed into the ink chamber Druc, which runs parallel to the roller, differences arise which lead to sealing problems on the doctor blades and thus to different wear of the doctor blade and to fluctuations in inking on the roller. An uneven formation of the rotating paint roller in the ink chamber also leads to fluctuations in inking, caused on the one hand by the existing pressure differences and on the other hand by the friction of the paint roller on the outer surface of the ink chamber.
- the invention has for its object to provide a method and an associated device for inking a roller of a rotary printing press with highly viscous printing ink.
- the advantages that can be achieved with the invention are, in particular, that little printing ink is in circulation, which is advantageous when cleaning the ink fountain and changing the printing ink. Due to the lack of a specially shaped ink chamber, the rotating ink roller is undisturbed and even, which also leads to a uniform and intensive inking of the roller.
- the ink application is carried out in a simple manner by means of an open ink fountain with at least one doctor blade positioned negatively on the roller. Both anilox rollers and inkjet cylinders can be provided with printing ink.
- An ink fountain 1 open at the top has left and right side walls 2; 3 and two of the periphery 11 of a driven roller 4 adapted sealing end walls 6; 7.
- the ink fountain 1 extends over the entire length of the roller 4, the z. B. can be designed as an anilox roller or as a printing cylinder, at the bottom of the side walls 2; 3, a working squeegee 8 negatively positioned on the roller 4 and a closing squeegee 9 are interchangeably attached.
- the ink fountain 1 there is preferably highly viscous printing ink, which during the machine runs a color roller 12 which is movable in the horizontal direction A and rotates clockwise B. According to the direction of rotation of the roller 4, z. B. counterclockwise c, the ink roller 12 lies both on a part of the surface 11 of the roller 4 and on a work surface 13 of the doctor blade 8 and a ink roller 12 in productive direction C of the roller 4 delimiting guide surface 14.
- the guide surface 14 is z. B. from the inside of the left side wall 2 is formed and extends to the working surface 13 of the squeegee 8 at an obtuse angle alpha, preferably from 110 ° to 130 °.
- the angle alpha can also be designed as an obtuse angle of approximately 190 °.
- the working surface 13 is formed by the free squeegee width and the length of the working squeegee 8.
- the ink fountain 1 is between the 1st and 2nd or in the 1st or 2nd quadrant of a right-angled through the axis of rotation 17 of the roller 4
- doctor blade 8 can cooperate with a side wall 2 depending on the amount of the angle alpha. If the angle alpha is in the range of 180 °, then the working surface 13 and the guide surface 14 are in the same plane and can therefore also be clearly executed.
- the ink has a viscosity greater than 60 poise.
