Definitions

  • the invention relates to a device for stacking folded sheets according to the preamble of claim 1.
  • a device is already known from European Patent Specification 0 103 104 with which sheets or sheet packs can be rotated by 90 ° in their plane.
  • the reason for such a rotation of folded products is that, as a result of the fold, they are thicker on one side and that when the folded products are stacked, the fold thickness adds up, so that the stack becomes unstable from a certain stack height and tends to collapse.
  • it is only possible to turn folded products so that when alternating stacking of turned and non-turned products they form a stack with an even height on two opposite sides.
  • Such a stack formation is considerably cheaper than a stack of folded products formed without rotation, but the stability from a certain height will also no longer be sufficient.
  • the stacked products can only be opened if they have an overlap.
  • Such a known device for rotating certain folding products for example each of the odd-number incoming folding products, is also insufficient if the sheets or sheet packages with two folds, i.e. are provided with a longitudinal fold and a transverse fold arranged at right angles to this. In this case too, the known device would only allow height compensation, but not opening without a fold.
  • the object of the invention is therefore to provide a device with which a safe and positionally stable stacking of fold products, preferably each provided with a transverse and a longitudinal fold, is possible, the four sides of the stack each having the same height and opening without an overfold is possible.
  • a device for inserting folded single sheets into one another with the aid of two counter-rotating inserting wheels is known, by means of which a stack of folded sheets superimposed like a comb is produced.
  • the insertion wheels running counter to one another have openings which are subjected to a vacuum and are drawn to the vacuum by one side of a folded sheet lying between two arms of the insertion wheel, which occurs in the insertion wheel when the single sheet is at a certain angle , the folded single sheets are released into the two plug-in wheels, which are located in two chambers of the distributor wheels, which are offset by half their width, so that they move towards one another as a result of the centrifugal force and are placed on the stack like a comb.
  • the main disadvantage of this device is that only individual folded sheets can be processed, since in the case of a folded package, for example in a folded newspaper, the inside pages or sheets could no longer be held, i.e. would be thrown out of the inserting wheels as a result of the centrifugal force.
  • An advantage of the invention is that the stacked, comb-like sheets or sheet packs can be opened again without overlap, for example to insert inserts.
  • Fig. 1 shows two multi-page folded sheets 1 and 2 with pages 3 and 4 formed by a longitudinal fold, and cross-folded pages 5 and 6 and open pages 7 and 8 or 9 and 10.
  • the sheets 1, 2 are through different page design at their four corners 11 to 14 or 15 to 18 different heights. If they were simply stacked on one another according to the prior art, these differences would add up, so that the stack becomes unstable, slips or tips over a certain height.
  • Fig. 2 shows how after turning the sheet 1 by 180 ° and then stacking different corners on top of each other come to rest, whereby the differences in height or thickness compensate each other. If now every second sheet is rotated in the direction of arrow 19 by 180 ° and the sheets 1, 2 are also zigzag-shaped in the middle in the direction of arrows 20 and 21 in accordance with the invention when stacking (Fig. 3) 4 results in the stable shape of a stack 22 shown in FIG. 4. This stack 22 offers, for later sheet removal, access to closed folding edges 5 and 6, respectively, with the sheets 1, 2 opening in the middle.
  • FIG. 5 shows an embodiment variant of the stack formation according to the invention with the aid of a gripping robot 23.
  • the sheets 1 and 2 of gripper arms 24 and 25 are inserted from a longitudinal fold side 3 or by inserting a separating plate 26 or 27 fastened to these arms 24, 25. 4 captured here and pushed zigzag-shaped into each other by rotating the respective second sheet 1 by 180 ° with simultaneous easy opening, so that the stack 22 results.
  • FIGS. 6 to 10 show a further variant of the invention for stack formation immediately after a folder 29.
  • the sheets 1, 2 are divided into two sheet streams in a known manner by a splitting device 30 directly after leaving a folding jaw cylinder 28 of the folder 29, so that for example, as shown in Fig. 6, only the sheets 1 below and only the sheets 2 above are conveyed. While these continue to run unchanged, the lower folded sheets 1 are rotated with the aid of a method described in EU-PS 0 103 104 with an unchanged conveying speed in the conveying device 31 not by 90 ° but by 180 °. Both fold sheet streams are then braked to scale formation in conventional ribbon cables 32 and 33. The further procedure is shown enlarged in FIGS. 7 to 10.
  • conveyor chains 34 and 35 run on both sides of the shingled streams, to which guides 36 and 37 are fastened, in which rods 38 and 39 reciprocate in the arrow directions 40 and 41 can be moved here.
  • This movement is controlled by guide curves 42 and 43, the inclination of plates 46 and 47 fastened in the rods 38 and 39, which act as separating or spacing elements, being influenced simultaneously via levers 44 and 45.
  • the sheet metal 46, 47 can now be inserted between the sheet sides from the longitudinal fold side 3 or 4 in the direction of the arrow 40 or 41 and the inclination of the sheets 46 and 47 can be controlled of the stack 22 are carried out in the manner already described, the conveyor chains 34, 35 being fed towards one another (FIG. 7).
  • a third variant of the invention for stack formation with the aid of so-called zigzag support structures 48, 48 ' is shown, which e.g. are described in detail in DE Patent 36 21 832 C1.
  • the removal of the sheets 1 and 2 from the jaw cylinder 28 of the folder 29, the filling in the zigzag structures 48, 48 'and the storage of the filled zigzag structures 48, 48' in portable and storable cassettes 49 is e.g. shown in DE Patent 36 21 822.
  • Fig. 12 it is shown how two cassettes 49 and 49 'are positioned one above the other. With known, e.g.
  • the drives 51 and 51 ' are mounted in portable cassettes 53 and 53'.
  • the zigzag structures 48, 48 'with the sheets 1 and 2 located in them are completely pulled out of the cassettes 49 and 49' and are completely in the cassettes 53 and 53 '.
  • About drives 54 and 54 'clamping bars 55 and 55' are now raised so that they can clamp the individual sheets 2 at their lower end by moving them in opposite directions grippers 56 and 56 'in the direction of arrows 57 and 58, respectively .
  • the upper cassette 53 ' is now rotated in the arrow direction 59 by 180 °, so that the V-shaped sheets 2 upside down over the also V-shaped open arches 1.
  • the cassette 53 is now raised somewhat in the direction of arrow 60, the upper sheets 2 are lowered in the opposite direction in the direction of arrow 61 by means of the drive 54 'until they have reached the position shown in FIG. 16.
  • the structures 48 are now brought into the area of a drive 77 in the position shown in FIG. 18 in the position shown in FIG. 18, with the folded sheets 1 and 2 being interlocked (FIG. 20). They slide onto the mounting rails 78 and 79 and take up the space of a receptacle 80 which receives the sheets 1, 2 by moving upwards in the direction of the arrow 81. Before the now filled container is moved downward in the direction 82, the support structures 48 are completely pulled out by lateral movement in the directions 68 and 69 (FIG. 20). The stack 22 is thus formed and can be placed on the pallet 83 after pivoting by 90 °, after which the receptacle 80 is removed again and is ready for a new pickup. The stack is stable on its own.
