Definitions

  • the invention relates to a device for turning rollers on and off the preamble of claim 1.
  • a torsion-free roll adjustment is known from DE-C 415382.
  • In one Inking unit in particular for combined punching and printing machines, is an inking unit provided that contains adjustable and removable rollers. These rollers are on Pivoted levers. The swivel levers are driven by an articulated drive moves, which consists of a spindle-nut arrangement that is parallel to Roller axis is aligned. This arrangement is for setting or slow and parking the roller.
  • the object of the invention is therefore a device for turning on and off Rolls according to the preamble of claim 1 to provide the torsion-free works, has a simple structure and an even setting of rollers enables.
  • a part of an inking unit of a printing press is shown schematically.
  • this inking unit of the printing press roll on the surface of a plate cylinder 1 several application rollers 2 from. Are still in contact with the application rollers 2 Rubbing rollers 3.
  • Each intermediate roller 5 is at both ends on one Bearing lever 6 arranged.
  • Each bearing lever 6 is towards the friction rollers 3, 4 sprung.
  • the bearing lever 6 can be pivoted about an axis 7 of the friction roller 4 become.
  • cam rollers 8 are attached to each bearing lever. With the Cam rollers 8 is an actuating rod 9 in common contact.
  • the actuating rod 9 is shown in a longitudinal view.
  • the actuating rod 9 is mounted in a frame 12 of the printing machine so as to be longitudinally displaceable.
  • the adjusting rod 9 is shown in pairs associated with cam rollers 8 on the bearing levers 6, the bearing levers 6 being assigned in pairs to an intermediate roller 5.
  • the adjusting rod 9 has several curves 10. Each curve 10 has a position H on the one hand, at which a part of the cam rollers 8 are at a high point. On the other hand, each cam train 10 also has a position T, at which a part of the cam rollers 8 are at a low point.
  • the cam rollers 8 each face the deep point in position T, in this position the intermediate rollers 5 on the friction roller 4 and the friction rollers 3rd are employed.
  • Two bearing levers 6 each operate one of the intermediate rollers 5.
  • the adjusting rod 9 is in its longitudinal direction movable.
  • the drive 11 can consist, for example, of a small pneumatic cylinder or from outside the Frame 13 take place. In a particularly simple manner, this is one end of the Actuator rod 9 is formed as a piston of a cylinder which by the sliding guide Control rod 9 is formed in the frame 13.
  • Fig. 3 the position is shown in which the actuating rod 9 in the parking position for the Intermediate rollers 5 is shifted.
  • the drive 11 is extended, the opposite end of the actuating rod 9 in its sliding guide 12 in the frame 13 of the Inking unit is immersed.
  • the cam rollers 8 are now in position H on the high one Points of the curves 10 of the adjusting rod 9.
  • the positioning forces lie symmetrically on the actuating rod 9 and can thus no uneven load on the Generate control rod 9. This ensures that the two are arranged in pairs Bearing lever 6 operated exactly the same and thus also the corresponding intermediate roller 5 is adjusted or switched on and off exactly in parallel.
  • each can be provided, as shown in FIG. 1 Assign control rod 9 to at least two rollers. So that the cam rollers 8 of act on two sides of the adjusting rod 9 and thus for a further balancing of forces contribute. Separate curves 10 can be provided for each roller, so that different conditions for the adjustment of each roller to be considered separately are.
  • actuating rods 9 continue to be designed as rotationally symmetrical parts a relatively simple assignment of the cam rollers 8 to the actuating rods 9 is possible. A Adjustment of the curves 10 with respect to the cam rollers 8 is unnecessary. Also the slight pivoting movement of the cam rollers 8 relative to the adjusting rod 9 when and switching off the intermediate rollers 5 then has no adverse effects.
  • the intermediate rollers 5 are adjusted relative to the friction rollers 3, 4 by known means in the bearing levers 6.
