Definitions

  • the invention relates to a device for cyclic lifting and lowering a suction cup in the feeder Sheet processing machine with means for adjusting the Suction height.
  • DE 976 134 C is used to adjust the distance between the sheet stack and the suction cup, a suction cup gear provided at an angle between a roller lever and an operating lever by means of a Eccentric adjustment device is changeable.
  • the invention is therefore based on the object Vacuum cleaner drive form such that a Suction position of the vacuum cleaner without changing one transfer position is infinitely adjustable.
  • the advantage of the invention is in particular that a separated by the suction device, raised by the sheet stack Bow can be safely handed over to the vacuum cleaner.
  • Another advantage is the stationary arrangement of the Adjusting means. This measure makes it possible to Distance of the suction cup to the top of the sheet also during to cease operations.
  • An articulation point is advantageously provided a coupling causing the stroke of the vacuum cleaner deflect different trajectories by the
  • the hinge point is mounted indirectly on the adjusting means.
  • a Guide element e.g. B. guide rail
  • the guide rail by means of a Adjustment means can be pivoted about a bearing point fixed to the frame is arranged.
  • the bearing point also marks the "transfer point”.
  • a housing 1 for a suction cup transmission 2 is above one Sheet stack 3 arranged and has one in the clock frequency of a sheet feeder driven cam 4. This sits rotatably on a shaft 6 which is rotatable in the housing 1 is drivably mounted.
  • a curve edge 7 of Control disc 4 is in rolling contact with a Control roller 8.
  • a spring, not shown is fixed between the roller lever 9 and the housing 1 and ensures that the control roller 8 is constantly in Rolling contact with the curve flank of the control disc 4 is.
  • a first end of the roller lever 9 is pivotable on one Axis 11 mounted, which is attached to the housing 1.
  • On one second end of the roller lever 9 is with a first end a coupling 12 directed downwards.
  • On a second end of the coupling 12 is by means of a bolt 13 each a further coupling 14 and coupling 16 by means of a first Articulated in the end.
  • the couplers 12, 14 and 16 are independent pivoted from each other about the bolt 13.
  • the Coupling 16 is arranged horizontally and with its second End with an approximately parallel to the coupling 16 Arm 17 of a two-armed lever 18 articulated on one Articulation point 20 connected.
  • the second arm 19 of the The control lever 18 is at a right angle to the first arm 17 arranged.
  • Adjusting lever 18 pivotally mounted on an axis 21 which on Housing 1 is attached.
  • the adjusting shaft 22 is by means of a threaded connection (not shown) on Housing 1 rotatably mounted.
  • An adjusting knob 23 is arranged outside the housing 1.
  • a Mark 24 on the adjusting button 23 serves as an optical display an adjustment dimension, characterized by one on the External wall of the housing 1 attached scale 26.
  • the suction cup 27 articulated At a second end of the downward coupling 14 is a suction cup 27 articulated.
  • the suction cup 27 carries a tubular one at its end facing away from the coupling 14 Traverse 28, on which at least one lifting vacuum 29 is arranged is.
  • the suction cup 27 has three spaced apart rotatably mounted guide rollers 31,32,33, which for Achieving a vertical movement with a housing-fixed vertically arranged guide rail 34 in operative contact stand.
  • the rollers 31, 32 are imaginary Arranged vertically.
  • the third roller 33 is on the side imaginary verticals arranged so that the rollers 31,32,33 form the corner points of an imaginary triangle.
  • the bolt 13 of the articulation of the couplers 12, 14, 16 is located in a "transfer position" on a common imaginary Straight line, which is also the center line of axis 21.
  • the "transfer position” defines the position of the Lifting vacuum 29 to at least one at the same height above the Sheet stack 3 arranged drag vacuum 36, to which one of the Sheet stack 3 by means of the lifting suction 29 raised sheet for Pass on to the sheet processing machine becomes.
  • An "intake position” defines the position of the Hubsaugers 29 which this when taking over a sheet from Sheet stack 3 takes.
  • the position of this articulation point 20 is adjustable by means of the adjusting knob 23 by pivoting the adjusting lever 18.
  • a new cam track K is set in each case, each of which has the same starting point (corresponds to " Transfer position ").
  • the stroke s and, consequently, the distance a can be infinitely adjusted by means of the different adjustable distances of the cam tracks K, K n to the suction cup 29.
  • a guide roller 37 is provided instead of the coupling 16 .
  • This sits rotatably on the Bolt 13 and is in guide contact with a pivotable mounted guide rail 38.
  • the pivot point of the Guide rail 38 lies on or in the immediate vicinity of the Center line 35 so that the guide roller 37 in the "Transfer position" is on the center line 35.
  • the Guide rail 38 can, depending on the desired stroke characteristics have a straight or curved course.
