Definitions

  • the invention relates to a device for transferring paint according to the preamble of claim 1.
  • a known version of this type shows a lifting roller in the inking unit, which carries out a pendulum movement between the ink fountain roller and the friction roller and is mounted on a pendulum axis.
  • the control for the pendulum movement is designed as a control cam which transmits the movement via a roller lever.
  • the pendulum movement can be switched off by means of a manually operated mechanism, so that no color gets into the inking unit when the sheet feeder is switched off or the print is switched off.
  • This known embodiment is to be operated purely manually and transfers the ink strip as it is fed from the ink fountain roller without the transfer being used for improved ink guidance, which has a negative effect on the subsequent generation of a uniform ink film.
  • the object of the invention is to achieve an improved ink preparation in the inking unit, and as early as possible in the vicinity of the ink fountain, in order to improve the starting basis for the inking unit itself.
  • the subclaims contain advantageous configurations of the inventive solution and enable the pendulum movement of the lifting roller to be switched off by remote control.
  • the printing plate of the plate cylinder 2 is inked in a known manner.
  • the ink required for printing is filled in an ink fountain 3 and reaches the inking unit 1 via the ink fountain roller 4, the lifting roller 5 and the friction roller 6.
  • the pendulum movement of the lifting roller 5 transfers an ink strip from the ink fountain roller 4 to the friction roller 6, which then processed into a uniform ink film in the inking unit.
  • the lifting roller 5 is mounted on both sides on levers 7, which in turn are attached to a pendulum axis 8.
  • the pendulum axis 8 and thus the lifting roller 5 receive their pendulum movement between the ink fountain roller 4 and the friction roller 6 via a cam mechanism (not shown).
  • a control cam 9 is attached to the pendulum axis 8 and has a slot 11 for receiving a roller 10.
  • the roller 10 is fastened via a pin 12 to a lever 13 which is mounted on the machine side frame 16 via a bearing pin 14 and a self-aligning bearing 15.
  • a roller 17 is fastened via a bolt 18.
  • the roller 17 engages in a closed cam 19 of a cam 20, so that when the cam 20 is rotated, a pendulum movement is transmitted to the pendulum axis 8 via the lever 13 and moves it back and forth.
  • the lifting roller 5 simultaneously receives a back and forth movement which is carried out independently of the pendulum movement thereof.
  • the cam 20 is rotatably mounted on an axis 21 and this in turn via bearings 22 in the machine side frame 16.
  • the drive takes place via a spur gear 23 at a speed such that the axial back and forth movement of the lifting roller 5 takes place synchronously with the back and forth movement of the friction roller 6.
  • the direction of movement of the lifting roller 5 runs in the opposite direction when it bears against the friction roller 6. This creates a double wiping path between the two rollers.
  • a finger 24 is provided on the control cam 9 fastened on the pendulum axis 8 and also executes the pendulum movement of the lifting roller 5.
  • An adjusting cam 26 is mounted on a pin 25 below the finger 24, the pin 25 being fastened to the machine side frame 16.
  • the piston rod 28 of a pressure medium-loaded cylinder 29 engages via a connecting piece 27, which is also fastened to the machine side frame 16 by means of a screw connection 30.
  • the actuating cam 26 can be pivoted via the pressure medium-loaded cylinder 29 in such a way that it stops the lifting movement of the lifting roller 5 when it is pivoted into the region of the finger 24. Here, this rests on the friction roller 6, so that the ink transfer from the ink fountain roller 4 to the inking unit 1 is interrupted.

Claims (3)

1. Dispositif pour introduire de l'encre dans le dispositif d'encrage des machines à imprimer, comprenant un rouleau preneur (5) qui décrit un mouvement d'oscillation entre un rouleau d'encrier (4) et un rouleau baladeur (6), et transfère une bande d'encre du rouleau d'encrier (4) au rouleau baladeur (6) et, de celui-ci, l'introduit dans le dispositif d'encrage, le rouleau preneur (5) étant tourillonné des deux côtés sur un axe oscillant (8) par l'intermédiaire de leviers, caractérisé en ce qu'un mouvement de va-et-vient axial est transmis à l'axe oscillant (8) du rouleau preneur (5) au moyen d'une cane de commande (19), en ce que le mouvement de va-et-vient est exécuté en synchronisme avec le déplacement axial du rouleau baladeur (6), et en ce que, lorsque le rouleau preneur (5) est en appui contre le rouleau baladeur (6), le mouvement de va-et-vient du rouleau preneur s'effectue axialement dans le sens inverse du mouvement du rouleau baladeur (6).
2. Dispositif selon la revendication 1, caractérisé en ce que, sur l'axe oscillant (8) du rouleau preneur (5), est montée une came de commande (9), en ce que le galet (10) d'un levier (13) qui tourillonne dans le bâti latéral (16) de la machine est engagé dans la came de commande (9), et en ce que, sur le bras de levier opposé, est prévu un galet (17) qui est engagé dans un profil de came fermé (19).
3. Dispositif selon la revendication 1, caractérisé en ce que la came (9) présente un doigt (24) qui est prévu dans la région d'une came de réglage (26) pouvant pivoter sous l'action d'un cylindre (9) actionné par un fluide sous pression, de sorte que, lors du mouvement d'engagement de la came de commande (26), le mouvement de translation du rouleau preneur (5) peut être arrêté et que ce rouleau est en appui contre le rouleau baladeur (6).
