Definitions

  • the invention relates to a device for supplying a scaly arc stream from a sheet pile of a sheet feeder to a feed table of a sheet processing machine Machine with a belt table, with at least one revolving driven Suction belt is provided with at least two consecutively with suction acted upon suction boxes in operative connection, as well as with means for detecting the arc.
  • Such devices are well known.
  • the one by a sheet feeder of one Sheet pile isolated sheets are seen as shingled stream stream on one Transported belt table having suction belts, there detected by the suction belts and transported to the feed table.
  • the suction belts are in the area of sheet transfer pressurized by a suction box facing the sheet feeder, while in the area of sheet transfer to the feed table, the suction belts be subjected to negative pressure by one of the machine-facing suction box.
  • the respective foremost arc of the sheet flow is on the feed table with the leading edge guided against leading brands and so aligned to the front edge. following If the bow is e.g. aligned to the side edge.
  • EP 0 554 774 B1 it is proposed in EP 0 554 774 B1 to detect the supply of the last arc of the arc current. After the penultimate sheet has been withdrawn, the vacuum supply to the machine facing suction box is interrupted and connected to an overpressure source. This device is not applicable in the thin pressure range, since a defined guidance of the last sheet is not given to the leading brands.
  • the object of the invention is to modify a generic device so that regardless of the material to be processed, even the last arc of a sheet flow is easily aligned.
  • the object is achieved by a device according to the features of Claim 1 solved.
  • the solution according to the invention makes it possible, the last arc of a scaly arc stream regardless of the material condition defined on the front lays to apply. This will ensure that the entire process gets processed Material can be processed trouble-free.
  • a belt table 1 with a downstream feed table 2 is shown schematically in side view.
  • the belt table 1 has at least one suction belt 3, which is guided over an upper deflecting roller 4 and a lower deflecting roller 5 and tensioned by means of two rollers 6.
  • a sheet feeder not shown, facing suction box 7 and a lower, also not shown bow-processing machine facing suction box 8 is arranged. Between the suction boxes 7, 8 more suction boxes can be arranged.
  • the upper suction box 7 is connected via a suction nozzle 9 with a first vacuum source, not shown, and the lower suction box 8 via a suction nozzle 10 with a second vacuum source, not shown.
  • a suction nozzle 10 opening or closing actuator 11 is arranged at the suction nozzle 10 .
  • a ventilation flap 12 is further provided, which can be actuated by means of an adjusting device 13.
  • the belt table 1 is followed by the feed table 2, of which a table top 14 is shown. In your position on the feed table 2 leading marks 15 are shown.
  • the front marks 15 can be spent in the working cycle from the position on the feed table 2 in a pivoted-away from the feed table 2 position. Adjacent to the front marks 15, a sheet 17 to be aligned, to which a following sheet 18 is arranged downstream as the last sheet 19, is shown.
  • a double-sheet control 16 is further provided, while the upper guide roller 4 is assigned a cyclically operating swab roller 23.
  • the drive of the suction belt 3 in a sheet transport direction 25 is effected by a drive unit 20 assigned to the upper deflection roller 5.
  • the drive unit 20 is connected to a control unit 21 which is linked to the setting unit 11, the setting device 13 and the double sheet control 16.
  • Also connected to the control unit 21 are the machine controller 22 and an input unit 24.
  • the sheets separated by the sheet feeder are fed to the belt table 1 under suction and are picked up by the suction belt 3, supported by the swab roller 23 guided in the working cycle against the upper deflection roller 4.
  • the holding force acting on the sheet is realized by the negative pressure built up in the upper suction box 7 by means of the vacuum source connected to the suction nozzle 9.
  • the sheets are conveyed as a sheet flow from the suction belt 3, driven by the drive unit 20, in the sheet transport direction 25, wherein the respective foremost sheet of the sheet flow is transported as bow 17 ausuinfoder on the feed table 2 and with the front edge against the front marks 15.
  • the force acting on the sheet 17 to be aligned, initiated by means of the pressure prevailing in the lower suction box 8 negative pressure holding force is minimized by the underlap of the subsequent sheet 18 or completely canceled.
  • the sheet 17 to be aligned can be easily applied to the front marks 15 and subsequently also aligned, if necessary, according to the side edge.
  • the sheet 17 After aligning the sheet 17 is withdrawn by means not shown and transported to the downstream sheet-processing machine. Simultaneously with the removal of the sheet 17 to be aligned, the follower sheet 18 is conveyed in the sheet transport direction 25. If a single arc is detected by the double sheet control 16 as a function of the position on the belt table 1 and the stagger spacing of the undercut arc current instead of a double or triple arc, this is detected as the last arc of the arc current and generates a signal. It is advantageous to assign the double-sheet control 16 to the belt table 1 in such a way that it detects the sheet 17 / subsequent sheet 18 or another sheet to be aligned with the underlap. The signal generated by the double-sheet control 16 is supplied to the control unit 21.
  • the last sheet 19 is detected and found in the control unit 21, the number of located between the front lays 15 and the last sheet 19 bow or the number of work cycles, which must be realized until the last sheet 19 rests as bow 17 ausuzinder to the front marks 15. If the sheet designated in the figurative representation as a follower sheet 18 is identified as the last sheet 19, the follower sheet 18 / last sheet 19 is transported against the leading marks 15 during the removal of the sheet 17 to be aligned by means of a sheet feeder, not shown. In this case, controlled by the control unit 21, the drive unit 20 is stopped, and thus the movement of the suction belt 3 is interrupted when the leading edge of the determined as last sheet 19 subsequent sheet 18 applies to the front marks 15.
  • the drive unit 20 can be stopped so that the last sheet 19 applies with a lower suppression of the front marks 15. Simultaneously or immediately before the application or within the power stroke, in which the transport of the last sheet 19, the vacuum supply to the lower suction box 8 is interrupted by the control unit 21 by means of the adjusting unit 11 and the venting flap 12 is opened by the adjusting device 13. Thus, the last sheet 19 can be aligned to the side edge and subsequently withdrawn.
  • the interruption of the vacuum supply by means of the adjusting unit 11 to the lower suction box 8 and the opening of the venting flap 12 by the adjusting device 13 is arbitrarily within the working cycle, in which the last sheet 19 is transported to the front lays 15, via the input unit 24 possible.
  • the release of the last sheet 19 can be adjusted depending on the material to be processed or on the design of the sheet system. For example, in a sheet feeder where side edge alignment is provided on the feed table 2 after alignment with respect to the leading edge, the ventilation of the lower suction box 8 must be earlier than in a sheet feeder with side edge alignment on a downstream cylinder.
  • the last bend 19 and its position on the belt table are detected by the double-sheet control 16. It is also possible to detect the final arc 19 by additional means.
  • the last sheet 19 and thus the sheet located on the feed table 1 / belt table 2 before this can be detected by the machine control.
