Definitions

  • the invention relates to a device for starting and stopping rollers according to the preamble of patent claim 1.
  • the object of the invention is therefore to provide a device for starting and stopping rollers according to the preamble of claim 1, which works torsion-free, is simple in construction and enables uniform adjustment of rollers.
  • the cam bar which is arranged transversely to the printing machine, produces a uniform setting of rollers. Due to the transverse movement, which can be made in small strokes, the roller to be started is completely identical moved on both sides. To simplify, several rollers can be moved via a single adjusting rod.
  • a part of an inking unit of a printing press is shown schematically.
  • several application rollers 2 roll on the surface of a plate cylinder 1.
  • Friction rollers 3 are still in contact with the application rollers 2.
  • Two intermediate rollers 5 are arranged between a further friction roller 4 and the friction rollers 3.
  • Each intermediate roller 5 is arranged on both ends on a bearing lever 6.
  • Each bearing lever 6 is spring-loaded in the direction of the friction rollers 3, 4.
  • the bearing lever 6 can be pivoted about an axis 7 of the friction roller 4.
  • cam rollers 8 are attached to each bearing lever.
  • An actuating rod 9 is in common contact with the cam rollers 8.
  • 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 part of the curve rollers 8 are at a high point. On the other hand, each curve 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 which position the intermediate rollers 5 are set against the friction roller 4 and the friction rollers 3.
  • Two bearing levers 6 each operate one of the intermediate rollers 5.
  • the adjusting rod 9 is movable in its longitudinal direction to adjust the intermediate rollers 5.
  • the drive 11 can consist, for example, of a small pneumatic cylinder or can take place from outside the frame 13.
  • one end of the actuating rod 9 is designed as a piston of a cylinder, which is formed by the sliding guide of the actuating rod 9 in the frame 13.
  • Fig. 3 the position is shown in which the actuating rod 9 is moved into the storage position for the intermediate rollers 5.
  • the drive 11 is extended, the opposite end of the actuating rod 9 being immersed in its slide guide 12 in the frame 13 of the inking unit.
  • the cam rollers 8 are now in position H on the high points of the curves 10 of the actuating rod 9.
  • the longitudinal movement during the adjustment prevents the actuating rod 9 from bending.
  • the actuating forces are symmetrical on the actuating rod 9 and can therefore not generate a non-uniform load on the actuating rod 9. This ensures that the paired bearing levers 6 are operated in exactly the same way and thus the corresponding intermediate roller 5 is adjusted or turned on and off exactly in parallel.
  • each roller can be assigned at least two rollers to each actuating rod 9.
  • the cam rollers 8 can thus act on the adjusting rod 9 from two sides and thus contribute to a further balancing of forces.
  • Separate curves 10 can be provided for each roller, so that different conditions for the employment of each roller have to be taken into account separately.
  • control rods 9 continue to be designed as rotationally symmetrical parts, a relatively simple assignment of the cam rollers 8 to the control rods 9 is possible. An adjustment of the curves 10 with respect to the cam rollers 8 is unnecessary. Also the slight pivotal movement of the cam rollers 8 with respect to the actuating rod 9 when the intermediate rollers 5 are turned on and off 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.
