Definitions

  • This invention relates to a chain stacker for a printing press and, in particular, is directed to a gripper chain stacker.
  • the invention is directed to means for controlling the grippers in chain stackers which have horizontally movable opening cams and which work in cooperation with a so-called following or after-gripper.
  • control cams are so arranged that the gripper travelling with the gripper chain opens before the sheet is dropped onto the stack and passes the sheet to a pneumatic after-gripper which, in turn, takes the sheet and brings it with a lessened velocity to the stacking plate of the stacking table.
  • the suction of the after-gripper is not enough to grasp and hold a sheet of heavy paper or cardboard. Consequently, it has been the practice to remove and not use the aftergrippers when handling heavy sheets or cardboard. The result has been that the heavy sheets or carboard strike the stacking plate without being reduced in velocity and thereby damage the front edge of the sheet and produces a sloppy stack.
  • FIGURE 1 is a front elevational view of the invention
  • FIGURE 2 is a side view of FIGURE 1 taken in the direction o the a row A;
  • FIGURE 3 is a cross-sectional view taken on the line 3-3 of FIGURE 1.
  • the gripper chain 1 carries sheet grippers 2 which grasp the sheets 3.
  • the leading edge of the sheets 3 strike the stacking plate 4 as they are deposited upon the stack.
  • the aftergripper 5 takes each sheet as it is released by the grippers 2 and moves the sheet with reduced velocity toward stacking plate 4.
  • the opening cam 6 has the position as shown in full lines in FIG- URE l.
  • the cam surface 7 bears upon the cam follower 7a to open grippers 2 at this position.
  • the construction is modified by extending the cam surface 7 by means of a curved cam arm 8 which is pivotally joined to cam 6 by pin 9.
  • Cam 6 is joined to a guide 16) in the form of an elongated slot which is slidably and turnably mounted on the axle 11 of the chain sprocket and a fixed stationary bearing 12.
  • Guide Iii is movable by a lever 13 connected at one end to guide 10 and at the other end to shaft 14 which is displaceable by a gearing 14a actuated by handwheel 15.
  • the guide 10 and cam surface 7 are displaceable substantially parallel to the surface of the stack of sheets to a position indicated by the dash-dot line.
  • a stationary bracket 16 is clamped to axle 11 and bearing 12 for holding in a fixed position a stationary member 17 which bears against the fiat surface 18 of the curved cam extension arm 8.
  • the free end of arm 8 is connected to lever 13 by a spring 19.
  • a chain stacker for a printing press said stacker having a horizontally displaceable opening cam for sheet grippers operating in conjunction with after-grippers
  • the improvement comprising a curved cam extension arm pivotally joined to said opening cam and having a surface forming a continuation of the surface of said opening cam, a stationary member bearing against said arm, and means for moving said opening cam into difi 'erent positions while keeping said arm substantially in the line of its curve and bearing against said stationary member to change the opening point of the sheet gripper while maintaining an unchanged closing point for said sheet gripper.
