Definitions

  • the invention relates to a sheet guiding device in the sheetfed press of printing machines with a bottom-working oscillating system, which detects a pre-aligned on one of the oscillating plant feed tray using aligned from top and front marks registration marks after the leading edge sheet accelerated to machine speed and to a downstream transfer drum passes, below the path described by the gripper tips of the gripper of the vibrating system a distributed over the sheet width on a shaft arranged Bogen Gustaven sheet guiding device is provided, which can be brought by pivoting the shaft in such a position that the underside of a peeling sheet facing Surface of the sheet guiding device extends at least just above the described by the gripper tips of the oscillating system and the deck marks tracks.
  • Such a sheet guiding device is known from DE 43 22 416 C2.
  • the sheet deflections of the sheet guiding device are distributed over the maximum arc width at a distance between the grippers of the oscillating system mounted rotationally fixed on a common shaft and periodically by an adjusting device from a position below the path described by the gripper tips of the vibrating system located in a location above this track pivoted.
  • the object of the invention is to form a generic sheet guiding device such that a trouble-free processing of all arisen within a format range sheet is possible.
  • the object is achieved by a sheet guiding device.
  • Claim 1 solved.
  • a feed table 1 with a sheet 2 and a subsequent sheet 3 is shown schematically in side view.
  • a front mark 4 and 5 deck mark existing 6 is shown at its position on the feed table 1.
  • a gripper 7 a vibrating system 8 is also shown.
  • the oscillating system 8 is a gripper 10 having transfer drum 9 downstream, which is mounted in the bearing point 19.
  • Concentric to the bearing point 19 are stationary and rigid sheet guiding elements 11 are arranged below the transfer drum 9.
  • the sheet guiding elements 11 is associated with a sheet guiding device 13 which extends below the path described by the tips 7.1 of the gripper 7 on its way between the feed table 1 and the transfer drum 9 and extends approximately to the feed table 1.
  • the sheet guiding device 13 consists of over the max.
  • Sheet width distributed sheet deflections 20 which are rotatably connected to a parallel to the transfer drum 9 shaft 14 which is rotatably mounted in a bearing point 12 and by means of a rotationally fixed on the shaft 14 clamped roller lever 15 via a roller 18 and a tension spring 16 in operative connection with a cam 17 is held.
  • the shaft 14 can be pivoted about the roller 18 and the roller lever 15 and thus the sheet deflections 20 of the sheet guiding device 13 are moved to a position in which the top of the sheet guiding device 13 on the by the gripper tips 7.1 of the gripper 7 during movement to the transfer drum 9 described track and on the located in the position on the feed table 1 deck marks 5 runs (dashed line in Fig. 1).
  • FIG. 1 the arrangement of the sheet deflections 20 on the shaft 14 is shown in FIG.
  • a first sleeve 22 and a second sleeve 23 are provided, which are non-rotatably connected to the shaft 14 but slidably connected in the axial direction.
  • the sheet deflections 20 for example by means a clamping connection arranged rotationally.
  • a bearing piece 24 is still rigidly connected, in which a double-acting adjusting elements 25 is fixed.
  • the adjusting elements 25 engages via a first actuator 26 to a first adjusting lever 28 which is connected to the first sleeve 22 at.
  • the adjusting elements 25 engages via a second actuator 27 to a second adjusting lever 29, which is connected to the second sleeve 23.
  • the sleeves 22; 23 are moved over the first actuator 26 and the first lever 28 and via the second actuator 27 and the second lever 29 from the machine center 21 to the sides or back to the machine center 21.
  • the sheet 2 and the follower sheet 3 are conveyed by a belt table, not shown, against the located in the position at the feed table 1 Anlegmarken 6, caught by the deck marks 5 and aligned to the front marks 4 after the leading edge.
  • the Anlegmarken 6 are pivoted to a position below the feed table 1 and the sheet 2 is transported to the transfer drum 9. During this time, the withdrawing sheet is still performed on the feed table 1, the Anlegmarken 6 are pivoted back to feed table 1 for aligning the follower sheet 3, wherein simultaneously the shaft 14 is rotated in the bearing point 12, so that the sheet deflections 20 of the sheet guiding device 13 in a be placed so that the underside of the sheet facing surface of the sheet guiding device 13 is at least just above the path described by the movement of the gripper tips 7.1 and in the region of Anlegmarken 6 on the upper side of the deck marks 5.
