Definitions

  • the invention relates to a method for separating sheet material for a Processing machine, in particular for printing machines.
  • Feeders with a suction head are known, in which sheet-like materials are picked up and lifted from the feeder stack by means of a lifting suction device, then transferred to the suction device in the direction of sheet travel and transported to a processing machine by means of a feed table.
  • the separation of sheet material is known for example from DE 2 856 811 A1.
  • a sheet feeder is used, which has separating suction and drag suction devices, which transport the separated sheet over a feed table to an infeed printing unit of a rotary printing press.
  • the sheet feeder has a device for conveying that is free of bending deformation in the direction of sheet travel to the printing unit, with simultaneous pivoting of the sheet in its own plane.
  • the device has a slide which is guided in the translation direction and on which the suction cups can be pivoted about the axis of the plane of movement of the slide.
  • JP-A 61-75748 is one Separating device for sheets from a box-shaped container Stack known.
  • the upper bow is from one to one Suction device vibrating axis of rotation sucked in and simultaneously through the Swinging movement against an edge of the box-shaped acting as a stop Container compressed, so that a compression fold is created.
  • This is followed by a Reversal of movement of the suction device by swinging it in the direction of sheet travel, the pleat is leveled, and only then does sheet feeding begin.
  • the object of the invention is a method for separating sheet material develop through which the friction between adjacent arcuate materials is reduced.
  • the sheet feeder unit shown in Fig. 1 consists of a feeder stack 1, the one has upper arch 2.
  • the vacuum 3 and drag vacuum 5 has.
  • the feeder stack 1 is a feed table 6 downstream, which in turn a printing unit 8 of a sheet processing Printing machine is subordinate.
  • the suction head unit 4 sucks the upper sheet 2 from the feeder stack 1 and conveys it Sheet 2 a short distance (Fig. 2, arrow 11) the sheet travel direction 7 (away from the feed table 6 or the printing unit 8). Then the suction head unit guides 4 a reversal of movement with the sheet 2 and transports this sheet 2 in the sheet running direction 7 to the feed table 6.
  • the suction head unit 4 conveys the sheet 2 a short distance out of the sheet running direction 7. Then the suction head unit 4 leads again a reversal of movement with the bow 2 from (Fig.2, double arrows 10,12) and transports this sheet 2 in the sheet running direction 7 to the feed table 6.
  • the sheet 2 is conveyed out of the sheet running direction 7 by an oscillating movement (double arrow 10) of the sheet around a vertical axis 9 intended to run to the horizontal plane of the feeder stack 1 or to the upper sheet 2, or a linear movement (double arrows 12) at an angle ( ⁇ 1 , ⁇ 2 , ⁇ 3 ) reachable to the sheet running direction 7.
  • This process separates the sheet 2 from the feeder stack 1 without getting caught.
  • the relative movement between the upper sheet 2 and the adjacent (underlying) sheet in the feeder stack 1 as a result of the described procedure of the sheet 2 noticeably reduces the holding friction.
