Definitions

  • the invention relates to a sheet feeder of a sheet-fed press, comprising a sheet stack and a device for separating and feeding sheets to the sheet-fed press, this means having means for separating the uppermost sheet from the sheet stack, a conveyor for transporting the sheet relative to the sheet stack above it. Furthermore, a transport device for taking over the sheet from the conveyor and for transfer to a suitable for supplying the sheet to the sheet-fed press sheet transport device is provided.
  • the respective uppermost sheet of a sheet pile is detected and raised for separating from the one extractable lifting suction extraction in the region of the sheet trailing edge.
  • the isolated sheet is transferred to transport suction, which transport the sheet in the sheet transport direction to the conveyor.
  • the clock rollers of the conveyor are controlled against a transport roller, so that the sheet can be detected by the active pairing clock rollers / transport roller.
  • the sheet clamped between the transport roller and the taker rollers is conveyed to a belt table, guided by the latter against front carriages pivotable into the path of the sheet and thus aligned with the leading edge.
  • the aim is that the sheet to be aligned arrives at the leading brands with the least possible imbalance, since the oblique sheet correction adversely affects the overall productivity of the printing press.
  • a solution is presented in which position errors of the sheets are to be compensated for when transferring to transport rollers.
  • a suction cup provided with transport suckers the sheet feeder, in which the sheet during a transfer phase from the transport suckers to the transport roller or to the clock roller performs no relative movement to the transport suckers.
  • the suction head of the transport suction is performed by a drive approximately parallel to the transport direction of the sheet and arranged to an additional, beyond a positive displacement generated by the drive way in the transport direction against a spring force movable.
  • the speed of the transport suction is in this case smaller than the transport speed of a gripped by the transport roller sheet, so that an extension of the sheet takes place and ensures better sheet transport, especially for thin sheets.
  • the invention has for its object to provide a sheet feeder with a device for separating and feeding sheets to a sheet-fed press, which guarantees a streamlining of the sheet in the transfer to the clock roller / transport roller and thus an exact location in the further processing.
  • a sheet feeder 1 is shown with an existing sheet of sheet 9 pile 3.
  • the sheet stack 3 rests on a stacking plate 31. This is held by conveyors 33 in the form of ropes or chains, which are articulated on the frame 2 of the sheet feeder 1 and operated by a lift, not shown.
  • the sheet stack 3 rests with its front edge 34 on a stack stop.
  • a sheet separator 4 is arranged in the region of the trailing edge 35 of the sheet stack 3.
  • the sheet separator 4 contains separating suction 41 and transport suction 42.
  • the separating suckers 41 perform a lifting movement for separating the uppermost sheet 9 from the sheet stack 3 from.
  • the separating suction 41 perform a translational movement in and against the sheet transport direction T from. Separating suction 41 and transport suction 42 are arranged at intervals next to each other transversely to the sheet transport direction T.
  • a flap shaft 32 extending over the width thereof is provided. This is arranged in the upper region of the sheet stack 3 and can be pivoted from a vertical position in the counterclockwise direction.
  • the flap shaft 32 is arranged downstream of a transport device 7, which consists of a permanently driven, over the width of the sheet stack 3 extending transport roller 72 and a plurality of clock rollers 71.
  • Each of the clock rollers 71 is rotatably mounted at the end of a lever 73 and hinged at a frame point 74 pivotally.
  • the transport roller 72 is formed as a suction roller and also clocked operable.
  • the transport device 7 is followed by an approximately horizontally extending guide plate 6, to which an inclined belt table 5 is arranged downstream.
  • FIG. 2 It can be seen that between the flap shaft 32 and the transport device 7, a further conveying member in the form of a suction roller 8 is arranged.
  • the suction roller 8 is supplied with suction air for detecting and holding the sheet 9, but rotates continuously.
  • the suction air can also be clocked.
  • the 9 imposed by the transport sucker 42 to the sheet transport speed v 1 is below the by the suction roller 8 mediated transport speed V2.
  • the respective uppermost sheet 9 of the sheet stack 3 is detected by the separating suckers 41 in the region of the trailing edge of the sheet and separated from the subsequent sheet. This is supported by blowing devices, not shown, which lead blowing air between the uppermost sheet 9 and the next sheet.
  • the floating in its entirety sheet 9 is passed from the separating suckers 41 to the transport suction 42, which lead them with the transport speed v 1 in the sheet transport direction T.
  • the flap shaft 32 is pivoted counterclockwise, so that the sheet 9 reaches with its free end in the region of the suction roller 8 and is detected by this.
  • the sheet 9 experiences the higher transport speed v 2 . This has the consequence that this is tightened and passes in this form between the transport roller 72 and the lifted from the transport roller 72 clock rollers 71.
  • the clock rollers 71 are now performed by acting on the lever 73 (not shown here) control elements against the transport roller 72 , As a result, the sheet 9 is clamped between the clock rollers 71 and the transport roller 72 and thus guided over the guide plate 6 to the belt table 5.
