Definitions

  • the invention relates to a folding and transport device with devices for folding sheets or packages of sheets and then transporting them to a storage or further processing station.
  • the folding and transport device comprises a collecting cylinder 1 and a folding jaw cylinder 2. From the latter, the folded sheets or sheet packs (folded copies) 4 are transferred to an area 5 for forwarding to a storage and transport system 6 of a ribbon line 9, 10 passed.
  • the belt line 9, 10 can advantageously be operated at a lower speed than the peripheral speed of the cylinders 1, 2.
  • the folding jaw cylinder 2 is equipped with folding jaws 3, into which a folding knife 7 of the collecting cylinder is conventionally used for transferring the sheets 4 to be folded 1 is pushed in.
  • Fig. 2 shows a detail in the direction of arrow II of FIG. 1 in an enlarged view.
  • the folding flap 3 is shortened compared to the sheet to be folded and preferably also compared to the folding knife 7.
  • a loop 8 is thus formed on one side of the sheet during the folding process, since the sheet is not folded in this area, ie is not broken sharply.
  • Fig. 3 shows a side view in the direction of arrow III of Fig. 2, the folding process.
  • the fold according to the invention thus creates a loop 8 on one side of the folded sheets 4.
  • a similar loop 8 can also be formed on the other side of the sheet 4 on the right side, if this is desired.
  • the folding according to the invention is possible in such a way that the folding flaps 3 shown shortened in FIG. 2 have the usual length or width, in which case the supplied sheets or sheet packs 4 to be folded are laterally shifted into the Folders 3 arrive, so that they protrude on one side over the folder and the associated folder. In this case too, the protruding part is not folded, so that a loop is formed on one side.
  • Fig. 1 also shows how the folded sheet 4 is transferred in a known manner in the area 5 to the preferably rotating at a lower speed tape lines 9, 10 with the help of a transport roller 11 after the folding process.
  • 4 shows an enlarged view of how the sheet 4 folded according to the invention is guided between the ribbon cables 9, 10, namely in such a way that the loop 8 is not clamped or compressed between the ribbons 9, 10. This can be achieved in that the loop 8 projects beyond the belts 9, 10. It is therefore essential to the invention that sheets 4 that are not completely folded through with the loop 8 are always taken over or continued in such a way that the guide does not compress the loop 8.
  • the fold formation according to the invention can also be produced with a pair of folding rollers, between which a sheet to be folded or a sheet package is pushed by means of a folding knife.
  • folding devices are referred to as drum folds and are usually used to produce a longitudinal fold.
  • partial shortening can be achieved by shortening the pairs of folding rollers accordingly or by feeding the sheets or packages of sheets to be folded laterally offset, so that a loop is formed on one or possibly on both sides.
  • folding machines which can also be used.
  • FIG. 5 shows in the direction of arrow I of FIG. 1 how in an advantageous manner in this embodiment a controlled tongue 13 dips with its tip into the loop 4 at the end region of the ribbon cables 9, 10.
  • the sheets 4 are transferred to a storage and transport system 6, which is pulled apart by a rotating timing toothed belt (not described in more detail) and with the aid of a screw for receiving the folded sheets 4.
  • this system consists of zigzag-shaped interconnected elastic sheets, between which V-shaped support arms are arranged, which are also spread when the zigzag or accordion-shaped structure is pulled apart.
  • the wedge-shaped tongue 13 (see for example FIGS. 10-13) is controlled via upper and lower cam disks 14.
  • cam roller 15 On the cam disc 14 there is a cam roller 15, which act on the plunger 16 on the upper or lower region of the tongue 13 so that it can be tilted by the cam discs 14.
  • Compression springs 17 press the cam rollers 15 against the cams 14 and bushes 18 and 19 are used for guidance.
  • FIG. 6 to 13 show in detail the opening process of the sheets or sheet packs 4 folded according to the invention through the tongue 13.
  • the sheet 4 is inserted between the two in the direction of the arrow rotating cams 20 arranged on both sides, through which the loop 8 is folded by pressing, as shown in FIG. 6 and the associated side view in FIG. 10. 7 and 11 show further immersing the tongue 13 between the bow halves 4a, 4b.
  • the cams 20 have now continued to rotate to give scope for further immersion.
  • the upper part of the tongue 13 already leaves the arch area again, while the lower wider or thicker part of the tongue 13 opens the arch 4 to such an extent that V-shaped holding and spreading tongues 21, 22 of the transport system 6 can pass between the bow halves 4a, 4b during the transfer.
  • the tip of the tongue 13 is again ready for penetration into the next sheet 4, while the lower part is still in the area of the sheet 4.
  • 14 to 17 show a different design and control of the tongue 13 described above.
  • the tongue consists of two halves 23 and 24, which are controlled independently of one another but otherwise using the same means as described in FIGS. 6 to 13 .
  • the shape of the tongue halves 23 and 24 taken together corresponds to the wedge shape, which also has the tongue 13.
  • 14 to 17 show the timing of the control of the tongue halves, which in effect correspond to the control of the tongue 13.
  • FIGS. 18 to 22 show a further possibility of training the tongues with the aid of which the folded sheets 4 can be opened.
  • These consist here of two disks 25 and 26 rotating in a clockwise manner in the direction of the arrow, which are increasingly stronger again in the circumferential direction, that is to say are also wedge-shaped in this direction.
  • the shape of these disks is from FIGS. 18 to 21 and from the side view of FIG.
  • Fig. 22 can be seen.
  • the washers have a tip 27 for better penetration between the bow halves or into the loop 8.
  • the disks 25, 26 rotate so that the bow halves 4a, 4b are pressed apart by their increasing thickness.
  • the arching halves 4a, 4b are thus pushed apart in principle in the same manner as described above in connection with the tongues 13 and the tongue halves 2.3, 24. Due to the existing recesses in the tongues or disks 25, 26 to complete the fold, d. H. to squeeze the loop 8 in certain circumferential positions, the rotating cams 20 are activated.
  • tongues were inserted between folded sheets or sheet packs in order to force the halves of the sheets or sheet packs apart.
  • inserts for example sheets or folded products, from the side instead of the tongues 13, 22, 23 or 25, 26 inserted into the loops 8.
  • the introduction of such sheets or folded products can take place from both sides and from the left and from the right when creating loops on both sides. This way of introducing objects in the form of sheets or folded copies is described in detail below.
  • FIG. 23 shows the cyclical transfer of two partially folded sheets 28 and 29, each of which has a loop 30 and 31, respectively.
  • both sheets are held between sheets 33 and 34, respectively, and positioned so that the corner 32 of the sheet 29 can be steered into the loop 30 of the sheet 28.
  • the sheets 33, 34 have recesses 35, 36 so that the loops are retained.
  • the sheets 29 are then pushed completely between the halves of the sheet 28.
  • grippers are suitable, each of which grips the sheet 29 at the top and introduces it into the sheet 28 by a transverse movement. The movement required for this such gripper can, for. B. in a simple manner by appropriately shaped guide rails. If they are saved, the loops 30, 31 are retained so that the process can be repeated several times.
  • loops 8, 30 and 31 are used in the manner according to the invention for introducing tongues or other segments for the later opening of folded products or for inserting sheets or folded products.
