Definitions

  • the invention relates to a lifting drag suction gear for a separating member Sheet processing machine.
  • a suction cup transmission is known in which a suction height of the vacuum cleaner is adjustable such that no change in Transfer height of the sheet from the suction cup to a downstream suction cup.
  • a drive or gear for the vacuum cleaner movement is not shown.
  • On such a suction cup is z. B. known from DE 196 01 470 A1. This has a number of drag vacuums, which are controlled by means of a cam Gear and a guide a reciprocating translational transport movement To run.
  • DE22 20 353 shows a generic device, namely a lifting drag suction gear for a separating element "suction head" of a sheet processing Machine with a drivable control cam for the movement of the vacuum cleaner and a Crank drive for the movement of the vacuum cleaner.
  • a rotatable control cam for common adjustment of the transfer position of the lifting and drag vacuum is intended.
  • the invention is based on the object, in a compact design, a combined lifting-drag suction gear to accomplish.
  • the lifting suction gear for the or Vacuum cleaner and the drag suction gear for the drag vacuum cleaner or vacuum cleaners have common leadership. In this way, the sheet is handed over from Vacuum cleaners to the drag vacuum at a common height level.
  • the common guidance is advantageously in the form of a pivotable segment curve educated.
  • a sheet transfer takes place from the vacuum cleaner to the Drag vacs and the subsequent transport of the sheet through the drag vacs at a slight upward angle ⁇ of the trailing edge of the sheet.
  • the lifting suction device in addition to a lifting movement additionally performs a translatory movement.
  • a translatory movement With this measure it is Time window for the transfer of sheets from the vacuum cleaner to the vacuum cleaner enlarged, so that the handover quality is improved.
  • a rotary printing machine e.g. B.
  • a sheet 7 processing printing machine 1 has a feeder 2, at least one printing unit 3 or 4 and a delivery 6.
  • the Sheets 7 are removed from a sheet stack 8 and separated or scaly via a feed table 9 to the printing units 3 and 4.
  • the plate cylinders 11 and 12 each have a device 13, 14 for attaching flexible printing plates. Beyond that each plate cylinder 11; 12 a device 16; 17 for the semi or fully automatic Assigned printing plate change.
  • the sheet stack 8 rests on a stack plate 10 which can be raised in a controlled manner.
  • the withdrawal the sheet 7 takes place from the top of the sheet stack 8 by means of a so-called Suction head 18, which includes a number of lifting and trailing suction 19, 21 for the separation of the sheets 7.
  • a number of side and rear stops are provided to align the sheet stack 8, in particular the upper sheet 7 of the Sheet stack 8, a number of side and rear stops.
  • the suction head 18 has a drive shaft 25 which in the frame walls 24, 26 of the Suction head 18 is drivably mounted.
  • the drive can either be from the machine or can also be done from a separately controlled electric motor.
  • the drive shaft 25 carries a first control cam 27 for the movement of the vacuum cleaner 19, a second control curve 28 for the movement of the vacuum cleaner 21 and a third Control curve 29 for the movement of the probe element 23, which the stack tracking controls.
  • Each rocker 32, 33, 34 carries on one arm a rotatably mounted control roller 36; 37; 38 with the respective control curve 27; 28; 29 cooperates.
  • the rocker 32 is articulated at the end of its second arm with a suction cup bracket 39 connected, which in turn carries the vacuum cleaner 19.
  • the rocker 33 is at the end of its second arm connected to a vacuum cleaner support 41, which in turn is articulated Drag vacuum 21 carries.
  • the suction cup carrier 39 has a rotatably mounted control roller 42 and the Drag cleaner carrier 41 on a rotatably mounted control roller 43, which together with a pivotally arranged segment curve 44 are in rolling contact.
  • a compression spring 46 between the suction cup carrier 39 and the rocker 32 provides the System of the control roller 36 on the cam 27 and the control roller 42 on the Segment curve 44 sure.
  • a compression spring 47 between the vacuum cleaner carrier 41 and the rocker 33 provides the System of the control roller 37 on the control cam 28 and the control roller 43 on the Segment curve 44 sure.
  • the segment curve 44 is not about a fixed axis 48 of the suction head 18 illustrated actuating means pivotally mounted.
  • the vacuum cleaner 19 sets for sucking and picking up the Sheet 7 on the sheet stack 8.
  • the vacuum cleaner 21 is to this Time at its turning point at the end of the towing movement. After that Sucking the sheet 7 is lifted off the sheet stack 8 and, as in FIG. 6 shown, brought into a transfer position.
  • This transfer position has a adjustable height compared to the sheet stack 8.
  • the suction cup 19, the was aligned parallel to the upper layer of the sheet stack 8 during the suction phase, by a small angle ⁇ ( ⁇ approx. 10 ° to 35 °) with respect to the upper layer of the Sheet stack 8 pivoted.
  • ⁇ approx. 10 ° to 35 °
  • the drag cleaner 21 is also at the angle ⁇ inclined relative to the upper layer of the sheet stack 8.
  • the vacuum cleaner 21 begins, as in FIG Fig. 3 shows its forward movement. After the trailing edge of the sheet 7 den Vacuum cleaner 19 has completely passed, this is on the sheet stack 8 to the to suck in the next sheet 7a.
