Definitions

  • the invention relates to an oscillating application roller of an inking unit of a printing press with a roller shaft which is rotatably mounted on both sides in bearings and with a roller shell which is held on the shaft so as to be rotatable and axially displaceable relative to the shaft, with adjusting rings for limiting the rotation on the shaft Axial movement of the roller shell are attached and the roller shell can be driven to rotate and axially displaced via a friction roller resting on it.
  • the invention is based on the object of proposing an oscillating application roller with the features mentioned at the outset, which is distinguished in particular by a noticeable structural improvement.
  • bearings between the shaft and the casing should be able to be used, which can be produced inexpensively and whose maintenance, even over a long operating life, has only low requirements.
  • the adjusting rings on the roller shaft are infinitely adjustable and clampable, as a result of which the axial stroke of the applicator roller is adjusted accordingly, specifically as a function of the axial stroke of the friction roller resting on it.
  • four abrasive rollers can be used without the quality of the print suffering.
  • FIG. 1 schematically shows a longitudinal section through the essential components of an applicator roller according to the invention with a friction roller resting on it and a plate cylinder resting on it.
  • a roller shaft 2 is rotatably mounted in machine-fixed bearings 1. On it sit on both sides of the collars 3, which can be attached to the shaft 2 in a continuously adjustable manner.
  • a roller jacket 4 is pushed onto the shaft 2.
  • the jacket 4 can be rotated relative to the shaft via bearings 5 and axially displaced in the direction of the double arrow 6.
  • a friction roller 7 On the outer circumference of the jacket 4 is a friction roller 7, which is driven to rotate in the inking unit of the printing press in question and which is axially displaced (changes) in the direction of the arrow 6. This rotary movement and the axial displacement is transmitted from the friction roller 7 to the jacket 4 of the application roller, the application roller being axially displaced between the two adjusting rings 3 serving as stops.
  • Friction surfaces 8 or counter-friction surfaces 9 are formed between the inner sides of the adjusting rings 3 and the opposite end faces of the casing 4.
  • the figure on the right shows how the friction surfaces and counter-friction surfaces abut each other and the shaft 2 is thereby carried along.
  • the speed of the shaft is always synchronized with the speed of the casing and the shaft rotates in the bearings. This eliminates the need for an axial bearing, as was necessary in a known system.
  • the figure also shows a plate cylinder 10, on the circumference of which the oscillating applicator roller bears.
  • rings 11 e.g. made of rubber or plastic, which serve as wear parts when the applicator roller strikes the relevant collar 3 as an attenuator and to increase the friction.
  • the rings rotate with the roller shell and are attached to it in an exchangeable manner.
