Definitions

  • the invention relates to a dyeing or dampening unit of a rotary printing press with at least one applicator roller according to the preamble of claim 1.
  • DE 33 42 853 C2 shows an inking unit in which an inking roller can be pivoted about a distribution cylinder and at the same time can be adjusted to a forme cylinder.
  • the applicator roller is supported on both sides in levers.
  • Adjustable stops against which the levers can be moved serve to adjust the application roller to the forme cylinder.
  • a disadvantage is the effort for the adjustment and readjustment of the stops.
  • the object is achieved in a generic inking or dampening unit according to the invention with the features of the independent claim.
  • the application roller is placed against the forme cylinder with a defined force.
  • This contact force (reaction force) maintains the balance force and adjusts itself automatically.
  • the contact force can be selected and the setting of the so-called impression width can be made easily.
  • the position is insensitive to the positional deviations of the inking or dampening unit compared to the forme cylinder, since the application roller automatically finds its balance through a corresponding swiveling. Readjustments are also possible independently in this way, e.g. B. with swelling or shrinkage of the application roller or changes in diameter due to thermal expansion.
  • the invention will be explained in more detail using an exemplary embodiment.
  • the single figure shows schematically an inking unit of a rotary printing press with an applicator roller which can be adjusted to a forme cylinder.
  • the figure shows an inking unit 1, of which only one applicator roller 2 and one distribution cylinder 3 are shown.
  • a wedge ink fountain 4 is also shown as an example of an ink source, from which ink is transported to the distribution cylinder 3 via ink delivery rollers 19, which are only indicated schematically.
  • the applicator roller 2 is mounted on both sides with its pins 5, 6 in levers 7, 8.
  • the levers 7, 8 are pivotable about the axis of rotation of the distribution cylinder 3.
  • they are mounted, for example, on the journal of the distribution cylinder 3 or in side walls, not shown, in which the distribution cylinder 3 is also mounted.
  • a linear motor in the form of a working cylinder 9, 10 each articulates on the levers 7, 8.
  • a spring or an electrical pull magnet could also be used as the linear motor.
  • the levers 7, 8 can also be acted on by means of a rotary motor, for example by means of an electric, pneumatic or hydraulic motor or based on spring force.
  • a rotary motor 11 is thinly indicated in the figure with a position number in brackets.
  • the application roller 2 can be pivoted to a forme cylinder 12 by pivoting the levers 7, 8.
  • the working cylinders 9, 10 are preferably given a fluid Compressed air, supplied at a selected pressure p, the piston rods 13 of which extend and the levers 7, 8 together with the application roller 2 move into the position shown.
  • the pressure p is selected so that the positioning force acting on the levers 7, 8 generates an abutment force which causes the desired impression width B of the application roller 2 on the forme cylinder 12.
  • the position of the application roller 2 is then blocked by means of a blocking device 14.
  • blocking devices 15 can also be arranged on the levers 7, 8.
  • the blocking device 14 can also be released in the meantime in the course of the continuous printing, as a result of which the applicator roller 2 adjusts itself automatically in its employment, ie. H. in the case of, for example, swollen or shrunk application roller 2 or a change in diameter as a result of thermal expansion, the levers 7, 8 continue to adjust or retreat.
  • the inking unit 1 can also be operated without blocking the application of the application roller 2, as a result of which there is a permanent, independent readjustment.
  • the applicator roller 2 can be operated at a certain speed and for a certain period of time without blocking its position after it has been brought up to the forme cylinder 12 while the inking unit 1 is running in.
  • the application roller 2 can z. B. yield initial unbalance due to uneven color distribution.
  • the applicator roller 2 is initially also started with a higher setting force than later operation, in that the working cylinders 9, 10 are initially supplied with a higher pressure p. This avoids jobs that are too short due to static friction.
  • the application roller 2 can also be placed on a forme cylinder 12.1 of a different diameter while maintaining the position of the inking unit 1. This case is also shown in dash-dotted lines in the figure.
  • the swivel levers 7, 8 perform a larger swivel path when they are turned on until the applicator roller 2 comes to rest on the forme cylinder 12.1, which then takes place with approximately the same contact force and impression width B as on the larger forme cylinder 12.
  • the application roller 2 can also be a dampening application roller of a dampening unit 18 (indicated by the clamp position).

Abstract

L'objectif de l'invention est de créer un dispositif d'encrage ou de mouillage (1) caractérisé par une facilité de réglage et d'ajustage des rouleaux encreurs (2). A cet effet, le rouleau encreur (2), qui peut pivoter dans des leviers (7, 8) autour d'un rouleau de transfert (3), peut être mis en contact avec un cylindre porte-plaque (12) sous l'action d'une force de mise en contact commandée.
