Definitions

  • the invention relates to a method and Device for performing the method for Transport of bows in a chain bend one Rotary printing machine with at least two in Sheet running direction arranged optionally approachable Sheet stacking according to the preamble of claim 1.
  • DE-PS 11 76 672 shows a chain bend in the sheet with the last printed side down in Chain bow brackets are transported and after a Redirection of approx. 180 ° with the printed side facing placed on top of a stack of sheets.
  • the invention has for its object a method and an apparatus for performing the method for Transport of bows in a chain bend one
  • the sheet with a printed page is transported upwards in which the sheet is deposited with the printed side up on a second stack of sheets by means of a pair of Boom chains are made, with no switchable Guides to transport the sheets over the first stack of sheets are necessary.
  • the chain bow delivery according to the invention means that the sheets do not have to be guided over the first stack when they are delivered on the second stack seen in the direction of sheet travel. Damage to the sheets is therefore excluded and no aids for sheet guiding are necessary.
  • the use of common cantilever chains for several sheet stacks eliminates the chain wheels and their drives necessary for single chains. This enables inexpensive production of the chain arch arm.
  • the device according to the invention is in the drawing shown and is described in more detail below.
  • a chain bow delivery 1 of a rotary printing machine especially a sheet-fed rotogravure printing machine with respect to a central axis of this Rotary printing press constructed symmetrically. in the therefore only one page is described below.
  • an endless boom chain 2 runs with it at a distance a3, z. B. 940 mm, attached chain gripper systems 3.
  • the chain gripper systems 3 extending in the axial direction essentially consist of a cross member 4, which with a number of grippers 6, z. B. clamp grippers are provided. These grippers 6 clamp a sheet leading edge 7 of a sheet 8 between their gripper pads 9 and gripper tips 11 and can thus transport the sheet 8.
  • a sheet guide cylinder is well known Feeding devices have been fed a sheet 8.
  • this Bow guide cylinder e.g. B. a pressure cylinder 13, and a sprocket 14 is arranged.
  • This sprocket 14 leads the boom chain 2 in the area of the sheet transfer point 12 and then a second sprocket 16 steers the Boom chain 2 in an upper chain center 17 um. From this in the left part 18 of the chain boom 1 located sprocket 16 runs the boom chain 2 their upper chain center 17 towards the right right part 19 of the chain bend 1.
  • There there is a deflection sprocket 21 by means of which Boom chain 2 by approx. 180 ° into a lower chain center 22 is redirected.
  • the chain gripper systems 3 moved from right to left. In this direction the Boom chain 2 are along the deflection sprocket 21 of the lower chain strand 22 several, described in Example of a first and second sheet stack 23, 24 arranged.
  • the chain sheet delivery 1 each has a transfer drum 26, ie in the present example a transfer drum 26 between the first and second sheet stacks 23, 24.
  • This transfer drum 26 interacts with the upper and lower chain runs 17, 22 and is provided with one or more gripper systems 27 which are distributed uniformly over the circumference.
  • This transfer drum 26 is provided with a number of axially extending, U-shaped recesses 28 corresponding to the number of gripper systems 27 for receiving the chain gripper systems 3.
  • the chain gripper systems 3 can dip into these recesses 28 so that when the sheet is transferred, the gripper supports 9 of the grippers 6 of the chain gripper systems 3 are at the level of the gripper systems 27 of the transfer drum 26.
  • the upper and lower chain runs 17, 22 of the cantilever chain 2 touch the transfer drum 26 and thus form an upper and a lower transfer point 29, 31.
  • a partial length lT2 of the cantilever chain 2 to the right of the transfer points 29, 31, ie in the direction of the deflection sprocket 21, is one
  • the transfer drum 26 is provided with two opposite gripper systems 27 and accordingly with two cutouts 28 for the chain gripper systems 3.
  • the circumference u26 thus corresponds to twice the distance a3.
  • a circumference u21 of the deflection sprocket 21 is twice the distance a3 of the chain gripper systems 3.
  • the partial length lT2 of the cantilever chains 2 is 5 times the distance a3 of the chain gripper systems 3.
  • the gripper systems 27 of the transfer drum 26 are designed here as suction segments 27, but also known clamp grippers can also be used. It is also possible to use punctures.
  • the Transfer drum 26 is designed as a suction drum.
  • the gripper systems located on the transfer drum 26 27 can out of the outer surface 32 be movable and thus the leading edge 7 of the sheet Lift off the outer surface 32. This movement of the Gripper systems 27 out of the outer surface 32 controllable, for example, via curves not shown.
  • the chain bend 1 works as follows: At the sheet transfer point 12 from the printing cylinder 13 and chain gripper system 3, the sheet 8 is transferred from the printing cylinder 13 to the chain gripper system 3 such that a last printed side 34 of the sheet 8 lies in the direction of the opposite chain center 17. The sheet 8 thus detected on its leading edge 7 is transported by means of the chain gripper system 3 via the second sprocket 16 along the upper chain run 17 to the transfer drum 26. If the sheet is to be deposited on the first, right sheet stack 23, the grippers 6 of the chain gripper system 3 remain closed and the gripper systems 27 of the transfer drum 26 open or without suction air.
  • the sheet 8 in the chain gripper system 3 is transported to the deflection sprocket 21 and pivoted there by 180 °, so that the last printed side 34 is on top.
  • the grippers 6 of the chain gripper system 3 are opened and the sheet 8 is deposited on the first sheet stack 23 via known sheet storage systems, not shown.
  • a chain gripper system 3 For storage on the second sheet stack 24, a chain gripper system 3 transports the sheet 8 in the upper chain section 17 to the upper transfer point 29 of the transfer drum 26. There, the leading edge 7 of the sheet is gripped by a gripping member 27 of the transfer drum 26, ie the suction segment 27 is acted upon by suction air. Shortly thereafter, the grippers 6 of the chain gripper system 3 open. The sheet is now pivoted by the transfer drum 26 through 180 ° from the dispensing, upper chain strand 17 to the receiving, lower chain strand 22. Approx. 30 ° before the lower transfer point 31, the gripping member 27 of the transfer drum 26 pivots with the leading edge 7 out of the lateral surface 32 and the grippers 6 of the chain gripper system 3 arriving in the lower chain center 22 open (FIG.
  • the gripping member 27 of the transfer drum 26 is now pivoted back into the lateral surface 32, as a result of which the leading edge 7 of the sheet is brought between the gripper support 9 and the gripper tip 11 of the gripper 6 of the chain gripper system 3.
  • the grippers 6 of the chain gripper system 3 close and have securely gripped the sheet 8 at the lower transfer point 31.
  • the chain gripper system 3 transports the sheet 8 in the direction of the second sheet stack 24.
  • sheet deposit systems are arranged corresponding to the first sheet stack 23. The grippers 6 of the chain gripper system 3 open and the sheet depositing systems place the sheet 8 on the second sheet stack 24.
