Definitions

  • the invention relates to a device according to the preamble of claim 1.
  • the object of the invention is to demonstrate a takeover and transport device which removes folded products directly from the folding apparatus and slows them down to further processing units connected in "inline operation".
  • the invention is based on a folding apparatus belonging to the state of the art, which comprises a folding jaw cylinder and a folding knife cylinder which is attached to the latter and which can also be a collecting cylinder at the same time.
  • the fold is formed by pushing the sheets or packages of sheets lying on the folding knife cylinder into the open folding jaw in the folding jaw cylinder by a folding knife which is controllably arranged on the folding knife cylinder.
  • a rotating transport device z. B. a paddle wheel the folding products are then removed from the folder.
  • the invention can also be based on a so-called drum folding apparatus, in which a pair of folding rollers is used instead of the folding jaw cylinder and folding blade cylinder, between which the sheets or bundles of sheets are folded through by means of a folding blade pushing into this.
  • FIG. 1 shows a folding knife cylinder 1, which can also be a collecting cylinder, and a folding jaw cylinder 2.
  • Sheets or sheet packs 3 which were previously printed with one or more colors in a printing press, are pushed at the transfer point 4 in a known manner into open folding jaws 5 on the folding jaw cylinder 2 by means of folding blades arranged on the folding blade cylinder 1, after which the folding jaws 5 close to form the fold.
  • Continued rotation of the cylinders 1, 2 creates the triangular region A shown in FIG. 1 at or behind the transfer point 4, which can also be referred to as a "gusset".
  • the two halves of the folding products 3 are still on the folding knife cylinder 1.
  • the device according to the invention comprises a continuous endless transport device 7, for example a chain or a toothed belt.
  • the transport device 7 is guided around a deflection wheel 8, which is positioned above the wedge-shaped area A.
  • Elastic drivers 8 are fastened to the transport device 7, for example made of highly elastic spring steel, which, seen from the side, have a shape which can be seen particularly from FIGS. 6 to 8. With the aid of the elastic drivers, the folded products 3 are drawn off from the cylinders 1, 2 at an increased speed, with a slowdown then preferably taking place in the form of a scale in the subsequent straight-line transport area.
  • continuous endless transport devices 7 and 7 ' are preferably arranged on both sides of the folded product path, which are guided above the wedge-shaped area A around the deflection wheels 8 and 8'.
  • the distance or the width of the endless transport devices 7, 7 ' can be made variable in accordance with the width of the specimen to be processed.
  • the deflection wheel 8 is preferably positioned such that the speed of the ends 9a, 9a 'begins to increase after the ends in region A dip into the still open halves of the folding products 3, so that the folding products 3 move from the folding knife cylinder 3 at an increased speed prior opening of the jaws 5 can be removed.
  • the carriers made of highly elastic material are attached to the transport device 7 in a relaxed manner.
  • a stationary tensioning or deflection device for example in the form of a deflection rail 13, causes the drivers 9 to deflect outwards with the lower, angled ends 9a, 9a ', that means to be excited.
  • the variable deflection or tensioning device shown in FIG. 3 can be used for this.
  • a deflection element 14 which can be pivoted in an arc around the deflection wheel, is indicated, which practically causes an extension of the deflection rail 13 in the direction of the wedge-shaped region A. The point in time or the local point at which the tensioned drivers 9 are released can thus be determined individually.
  • damping elements 15 are provided at least on the inside of the track of the drivers 9, 9a, which can consist, for example, of an elastic material such as rubber or plastic or a magnet . If necessary, such damping elements 15 can also be arranged on both sides of the entraining path, so that their vibrations can be suppressed quickly.
  • the speed of the folded products 3 becomes lower as soon as the carriers 9 again, with scale formation be guided linearly on the transport device 7 in the direction of the deflection wheel 11.
  • the transport device 7 is guided around the deflection wheel 11 in such a way that the outwardly projecting ends of the drivers 9 run approximately at the center of the deflection wheel 11. This results in a further reduction in the speed of the folding products 3. If the pivot point of the drivers is placed exactly in the center of the deflection wheel 11, the speed "0" for the folding products 3 results when the transport device 7 is moved around the deflection wheel 11.
  • FIG. 4 shows schematically the time course of the deflection of the drivers 9 by the deflection rail 13 and their relaxation behind it, wherein a damping element 15 is indicated to dampen the vibrations after the release.
  • a further advantageous effect of the device according to the invention arises in that when the drivers 9 are guided around the deflection wheel 11 there is an automatic rotation of the drivers 9 in the folded products 3, as a result of which they are automatically spread (FIG. 10), since the drivers in area A with the angled ends 9a, 9b with the narrow side between the opened halves of the folded products 3 were introduced (Fig. 9). The transfer to other transport systems is made considerably easier.
  • a further relief at the transfer point results from the fact that the cranked shape indicated in FIG. 5 is selected for the deflection wheel, here for example a chain wheel 16.
  • a FIG Corresponding sprocket 16 can be used and by means of a further deflection element 13 ′′ the drivers 9, 9 'can be bent outwards again so that the ends 9a, 9b emerge from the folded product 3. This process takes place after the folded product 3 has been replaced by a subsequent one Transport system was threaded or taken.
  • FIGS. 6 to 8 show advantageous embodiments of the drivers according to the invention and their attachment to a transport system.
  • the upper ends of the drivers 9 can be provided with holes 23, 24, so that a transverse rod 19 can be plugged through these holes, which in turn is attached to a circumferential transport system, for example a chain 18 arranged in the center can.
  • the upper end of the drivers can be compressed by sliding rollers 20, 21, so that a displacement of the position of the drivers 9, 9 'on the crossbar halves 19, 22 is possible individually. This process can be automated.
  • the right half of the crossbar with 19 and the left with 22, the adjustment of only the right driver 9 has been shown.
  • FIG. 8 shows another variant for fastening the drivers 9, where the upper end of the drivers 9 is provided with recesses 27 on both sides.
  • two parallel arranged cross bars 25, 26, which in turn can also be fastened again to a preferably centrally arranged transport system, not shown here, is carried out by undulating bending of the upper end of the driver 9, its fixing between the cross bars 25, 26.
  • the position of the drivers on the cross bars 25, 26 can also be adapted to the width of the folded products 3.
  • Another advantageous embodiment results from chain transitions from round to straight over chain guides with certain functions for a smooth transition or special direction of movement.
