Definitions

  • the invention relates to a gripper control for a cyclically swinging pre-gripper for Single sheet transport in a sheet printing machine.
  • misfires i.e. H. Diagonal arch or Multiple sheets at the sheet transfer point on the feed table, must not be transported by the pre-gripper and passed to the subsequent cylinder.
  • the invention has for its object a Gripper control for a cyclically driven Pre-gripper for single sheet transport in one To create sheetfed press.
  • a switching mechanism is advantageously in the form a snap-in pawl provided that the Gripper opening / closing curve in a gripper opening position sets, so that the gripper at its swinging Transport movement remains open and therefore none Carries sheet transport.
  • the figure shows a schematic representation of the Gripper control in the cut.
  • a pre-gripper 1 of a sheet printing machine has one Gripper finger 2 and a gripper pad 3 and is at the end one swinging cyclically about an oscillation axis 4 driven rocker arm 6 arranged.
  • the Pre-gripper 1 has an articulated axis 7 on which the Gripper finger 2 is attached, and one the hinge axis pivoting lever 8.
  • the lever 8 carries at its end a rotatably mounted segment roller 9 with a Control contour 11 of a curve segment 12 in working contact stands.
  • the curve segment 12 is fixed to a frame Pivot point 13 is pivotally mounted.
  • One with the Curve segment 12 connected roller lever 14 carries on his free end of a rotatably arranged cam roller 16, the the control contour 17 a one-revolving Control curve 18 is in working contact.
  • a sheet 19 to be transported is in operation by Gripper 1 on the feed table 21 and transferred to one Pass gripper 22 of a downstream cylinder 23.
  • the pre-gripper 6 pivots around the Swing axis 4 in a transfer position in which the Bow 19 to the gripper 22 of the downstream cylinder 23 is handed over.
  • the segment roller 9 passes through a Closing area 24 of curve segment 12 to one: opening area 26 of the curve segment 12.
  • the closing area 24 additionally has one opening cams 28.
  • This measure opens the gripper finger 2 is held and it prevents a sheet transport is made.
  • the segment roller 9 gets into the area of the opening cam 28, the gripper finger 2 is still on little over the standard opening dimension compared to the Gripper pad 3 raised, d. H. a distance between Gripper finger 2 and gripper pad 3 is in the opening area, in which the segment roller 9 with the opening cam 28 in Working contact is greater than a distance that the Gripper finger 2 opposite the gripper pad 3 in the open Condition on the feed table 21.
