Definitions

  • the invention relates to a device for transporting and / or aligning a sheet of the machine for further processing in a sheet-processing machine, e.g. Printing press or punch is determined.
  • a sheet-processing machine e.g. Printing press or punch is determined.
  • the invention has for its object to provide an alternative solution that allows transport and / or alignment of a sheet on a feed table.
  • the transport or alignment movement of the sheet is produced by a movement of a bearing surface on which the sheet rests on the feed table.
  • the support surface can be moved in a preferred embodiment by a fast responding actuator such as a plunger coil or a magnet.
  • a fast responding actuator such as a plunger coil or a magnet.
  • pulsed suction air is used to fix the sheet during the transport or alignment movement on the support surface, wherein in a return movement, the holding force is canceled on the sheet.
  • the bearing surface itself carries out the transport or the alignment of the sheet by a directed deformation.
  • the support surface of lamellae or bristles, which are deformed by pressure from above. The pressure is exerted by the bow itself, in which it is pulled by pulsed suction air on the support surface.
  • a sheet alignment can be done here against fixed stops. Preferably, however, by a sheet position detection by means of sensors and possibly a sheet position correction after the desired-actual-value comparison.
  • a sheet 7 processing machine such as a printing press 1 or punch has a feeder 2.
  • the printing press also has at least one printing unit 3 or 4 and a boom 6.
  • the sheet 7 are removed from a sheet stack 8 and isolated or flake fed via a Zufiihrtisch 9 the printing units 3 and 4.
  • These contain in a known manner in each case a plate cylinder 11, 12.
  • the plate cylinder 11 and 12 each have a device for attaching flexible printing plates.
  • each plate cylinder 11, 12 is associated with a device 16, 17 for the semi or fully automatic printing plate change.
  • the sheet stack 8 rests on a controllably liftable stacking plate 10.
  • the removal of the sheet 7 takes place from the top of the sheet stack 8 by means of a so-called suction head 18, which, inter alia, a number of lifting and Schleppsaugern for the separation of the sheet 7 has.
  • suction head 18 which, inter alia, a number of lifting and Schleppsaugern for the separation of the sheet 7 has.
  • blower devices are provided for loosening the upper sheetfed systems and scanning elements for stacking.
  • For aligning the sheet stack 8, in particular the upper sheet 7 of the sheet stack 8 a number of lateral and rear stops are provided.
  • the feed table 9 has a device 19 for transporting and / or aligning the sheet 7 in its end region facing the sheet-processing machine 1. This is arranged in one or more recesses 42 in the feed table 9 and acts on an underside of the sheet 7.
  • the transport and alignment device 19 has a horizontally movable holding plate 22 with a support surface 23.
  • the holding plate 22 has a number of holes 24, which act on a lower side of the sheet 7 with suction air from a suction chamber 26.
  • a suction source such as a blower 27 generates a constant negative pressure in the suction chamber 26.
  • a pressure wave generator 28 At the bottom of the suction chamber 26, a pressure wave generator 28, for example, a speaker is arranged. With the help of the pressure wave generator, the underside of the arc is supplied with pulsed suction air.
  • the negative pressure level in the suction chamber 26 is hereby adjusted so that the negative pressure acting on the underside of the sheet alternates between a negative pressure (-p) and a pressure p (p ⁇ 0) in time with the frequency of the pressure wave generator 28.
  • the sheet 7 is alternately sucked by the holding plate 22 and held or released.
  • a quickly controllable actuator 29 is e.g. a plunger, solenoid or piezo actuator operated, which reciprocates the support plate 22 in a predetermined direction. This measure results in that the sheet 7 is transported and / or aligned.
  • the sheet 7 is first sucked on the holding plate 22 and held, then the support plate 22 is deflected by the actuator 29. At a turning point, the sheet 7 is released by applying the pressure level p (p ⁇ 0). The actuator 29 pulls the retaining plate 22 back to an initial position. Since only very small paths are generated in one step, this process is repeated until the desired position is reached.
  • the desired position is e.g. determined by conventional leading edge and side edge stops.
  • the sheet 7 is hereby e.g. aligned with stop means 31 at its front edge and / or a stop means 32 at its side edge.
  • a transport and / or alignment device 39 has a support member 41 for the sheet 7, which is arranged in the recess 42 of the feed table 9.
  • the support element 41 protrudes by a small amount a beyond the feed plane defined by the surface of the feed table 9.
  • the support element 41 has a number of lamellae or bristles 45, which can be bent in only one direction, preferably in the transport and / or alignment direction (see arrow in FIG FIG. 4 . 5 ).
  • the support elements 41 are arranged on a base plate 43, which has a number of suction openings 44, which are connected to a suction chamber 46.
  • the suction chamber 46 is of a Vacuum source 47, for example, a fan subjected to a constant negative pressure.
  • a Vacuum source 47 for example, a fan subjected to a constant negative pressure.
  • the sheet 7 is sucked resting on the support member 41 and thus leads to a deflection of the sheet in the transport and / or alignment direction while lowering the sheet 7.
  • arranged pressure wave generator 48 generates a vibration that leads to it in that a negative pressure (-p) and a pressure p (p ⁇ 0) are alternately applied to an underside of the sheet.
  • the support member 41 according to FIG. 5 can be changed by pivoting the support member 41 by means of a rotary drive 49 an alignment direction to align the sheet both in the sheet transport direction, transverse to the sheet transport direction or obliquely.
