Definitions

  • the invention relates to a device for the cyclical lifting and lowering of a lifting suction device in the feeder of a sheet processing machine with means for adjusting the suction height.
  • a lifting suction gear is provided for adjusting the distance between the sheet stack and the suction lifter, in which an angle between a roller lever and an actuating lever can be changed by means of an eccentric adjusting device.
  • the invention is therefore based on the object to design a vacuum cleaner drive such that a Suction position of the suction lifter is infinitely adjustable without changing a transfer position.
  • the advantage of the invention is, in particular, that a sheet that is separated from the lifting suction device and raised by the sheet stack can be safely transferred to the drag suction device.
  • Another advantage is the stationary arrangement of the setting means. This measure makes it possible to set the distance between the lifting suction device and the top of the sheet even during operation.
  • a guide element for. B. guide rail is provided for the hinge point, wherein the guide rail is pivotally arranged by means of an adjusting means about a bearing point fixed to the frame.
  • the bearing point also identifies the "transfer point”.
  • a housing 1 for a suction cup transmission 2 is arranged above a sheet stack 3 and has a cam disk 4 driven at the clock frequency of a sheet feeder. This sits in a rotationally fixed manner on a shaft 6, which is rotatably driven in the housing 1.
  • a curve flank 7 of the control disk 4 is in rolling contact with a control roller 8.
  • This is rotatably mounted on a horizontally arranged roller lever 9.
  • a spring, not shown, is fastened between the roller lever 9 and the housing 1 and ensures that the control roller 8 is constantly in rolling contact with the cam flank of the control disk 4.
  • a first end of the roller lever 9 is pivotally mounted on an axis 11 which is fastened to the housing 1.
  • a downward coupling 12 is articulated with a first end.
  • a further coupling 14 and coupling 16 are articulated to a second end of the coupling 12 by means of a bolt 13 and by means of a first end.
  • the couplers 12, 14 and 16 are pivotally mounted independently of one another about the bolt 13.
  • the coupling 16 is arranged horizontally and its second end is connected in an articulated manner at an articulation point 20 to an arm 17 of a two-armed actuating lever 18 arranged approximately parallel to the coupling 16.
  • the second arm 19 of the actuating lever 18 is arranged at a right angle to the first arm 17.
  • the adjusting lever 18 is pivotally mounted on an axis 21 which is fastened to the housing 1.
  • an essentially axially movable actuating shaft 22 is articulated.
  • the adjusting shaft 22 is rotatably mounted on the housing 1 by means of a threaded connection (not shown).
  • an adjusting button 23 is arranged outside the housing 1.
  • a Marking 24 on the adjusting knob 23 serves as a visual display of an adjustment dimension, characterized by a scale 26 attached to the outer wall of the housing 1.
  • a suction cup 27 is articulated at a second end of the coupling 14 directed downwards.
  • the suction cup 27 carries at its end facing away from the coupling 14 a tubular cross member 28 on which at least one lifting suction cup 29 is arranged.
  • the suction cup 27 has three mutually spaced, rotatably mounted guide rollers 31, 32, 33 which are in operative contact with a guide rail 34 arranged vertically and fixed to the housing in order to achieve vertical movement.
  • the rollers 31, 32 are arranged on an imaginary vertical.
  • the third roller 33 is arranged on the side of the imaginary vertical, so that the rollers 31, 32, 33 form the corner points of an imaginary triangle.
  • the bolt 13 of the articulated connection of the couplers 12, 14, 16 lies in a "transfer position" on a common imaginary straight line, which is also the center line of the axis 21.
  • the "transfer position” defines the position of the suction device 29 to at least one drag suction device 36 arranged at the same height above the sheet stack 3, to which a sheet lifted from sheet stack 3 by means of the suction device 29 is transferred to the sheet processing machine for further transport.
  • a “suction position” defines the position of the lifting suction device 29 which it assumes when a sheet is picked up from the sheet stack 3.
  • the articulated connection (bolt 13) is forced onto a cam track K via the couplers 12, 16.
  • 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 path K n is set, which corresponds to the same starting point (in each case "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 pivotably 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 lies in the "transfer position" on the center line 35.
  • the guide rail 38 can have a straight or curved course, depending on the desired stroke characteristic.
