Definitions

  • the invention relates to a gripper arrangement on sheet-processing machines, in particular sheet-fed offset printing machines according to the preamble of the main claim.
  • the grippers are fastened to a gripper shaft which carries a roller lever, the end roller of which rests on the outer edge of the curve segment; the gripper spring pulls this roller into the contact position and is attached at the other end to an opposite roller which bears against the equidistantly running inner curve of the curve segment and is seated on a roller arm rigidly extending from the gripper rocker arm.
  • the cam segment itself can be pivoted against spring loading, the pivoting movement being controlled by a feeler roller that rolls on a cam disk, preferably sitting coaxially with the associated drum of the sheet-guiding machine.
  • the configurations in this regard reduce the vibrations occurring in the gripper system and therefore reduce associated register differences; however, they are not suitable for optimally fulfilling all the essential requirements that occur with high-speed, high-performance printing presses. This in particular - as was found - not because the gripper spring itself has to be moved according to the high-speed rhythm of these machines, whereby not only their mass, but also the displacement in space transverse to the spring force plays a significant role.
  • the object of the present invention is to design a generic gripper arrangement in such a way that it has a simplified design and can also be used on high-performance machines.
  • a gripper arrangement is created on sheet-processing machines, in particular sheet-fed offset printing presses, in which the springs and spring bars loading the grippers, with storage as a mass, do not have to be moved together with the gripper rocker.
  • the grippers no longer receive their spring load from springs arranged directly on the gripper rocker, but rather from the spring load of the cam segment. Without increasing the weight of the gripper rocker, it is also possible to accommodate large springs with the most favorable adaptation of the desired characteristics.
  • the grippers can work in a rhythm adapted to the highest number of revolutions, there is also a considerable reduction in any natural vibrations of the system formed from the grippers and support.
  • a constructively favorable solution for the positive spring load control of the grippers is provided by the link cam control proposed according to the invention in this regard.
  • the three arms extending from a central shaft for the cam segment on the one hand and the introduction of force of the load springs on the other hand or for the feeler roller result in a kinematically and spatially advantageous division of the overall arrangement.
  • the gripper rocker 1 can be moved back and forth about the axis 2. It carries the gripper support 3 with the grippers 4, which are movably arranged for this purpose. The latter continues via the gripper shaft 5 into an arm 6 which carries a control roller 7 at the free end. This runs in a cam slot 8 of a cam segment 9. The control edges 8 'and 8' of the cam slot 8 are equidistant from one another and run concentrically to the center of the shaft 2.
  • the curve segment 9 is seated on an arm 10 which is arranged on a shaft 11 in a rotationally fixed manner.
  • the latter is supported in the machine frame cheeks 12 and carries on its one end projecting above it 11 'the lever arms 13 and 14.
  • a roller 15 This runs on a cam disc 16, which is preferably arranged coaxially with one of the drum axes sheet processing machine.
  • the other arm 14 is under the action of the compression springs 17. These are assigned the nuts 18.
  • the load on the compression springs 17 is such that the roller 15 is forced to the cam disk 16 in the contact position and the cam segment 9 is loaded in the direction of the arrow x.
  • the gripper takes over, for example, a sheet B which arrives in the direction of arrow P and is transferred by it to a gripper G of a drum T.
