Definitions

  • the invention relates to a splicer for bobbin-like coils Packaging material webs for packaging machines, in particular Cigarette packaging machines, with a device for feeding a free end of a packaging material web to a running Packaging material web, a knife for cutting off the running packaging material web after splicing and a device for connection of the two packaging material webs.
  • DE-C-3 929 981 describes a bobbin splicing device for Known cigarette packaging machines that work with pressure rollers, the packaging material web to be spliced in front of the nip is held by means of a terminal strip and from a recess of the neighboring Pressure roller is loosely arranged.
  • Clamping strip clear the packaging material web and the pressure roller grips the end with a friction section.
  • the splicing process has in this case with a greatly reduced conveying speed of the packaging material web and thus with a greatly reduced packaging speed Packaging machine to take place.
  • the object of the invention is to provide a splicer for bobbin-like wound packaging material webs of the type mentioned at the beginning create that allows at full bobbin speed without manual Splicing engagement.
  • Fig. 1 shows a schematic front view of a splicer for a cigarette packaging machine.
  • FIG. 2 shows a detail from FIG. 1 in detail.
  • 3 to 5 show different stages of the splicing process, as is done with a splicer according to FIG. 1.
  • a turntable 1 is provided, which by means of a Not shown drive can be rotated back and forth by 180 ° or can be rotated further.
  • the turntable 1 has two, preferably one above the other arranged, provided with expandable jaws 2 for a bobbin 3 'or 3' ', which are provided with a bobbin core 4 is in which the receiving pin 2 engages and clamps it.
  • the expiring Bobine 3 '' is according to the illustrated embodiment over the new bobbin 3 '.
  • the bobbins 3 ', 3' ' can for example for the production of the inner paper, the outer paper or the wrapping film serve from cigarette packs.
  • the new bobbin is 3 'to open first.
  • a lever 5 is about an axis 6 rotatably provided, a carriage 7 at its free end wearing.
  • the carriage 7 is against the outer circumference of the lever 5 Bobine 3 'pivotable and carries a schematically illustrated knife 8, that with the carriage 7 transverse to the packaging material web 9 'of the bobbin 3 'is movable to cut them.
  • It is also a radially displaceable one Friction body engages with the outer circumference of the bobbin 3 ' bringable, which causes the packaging material web 9 'lifts off. This can be assisted by blowing air directed at the interface will. The blown air can with increasing strength or clocked be applied.
  • the exposed end of the packaging material web 9 ' is in Blown towards a web material gripper 10 and caught by this.
  • the web material gripper 10 comprises a two-armed lever 11, the about an axis 12 between two end positions (shown in Fig. 3) is rotatable back and forth.
  • the shooting position for the end the packaging material web 9 ' is the web material gripper 10 with a Roller 13
  • the free end of the lever arm directed towards the bobbin 3 ' 11 'of the lever 11 is arranged on the circumference of the bobbin 3'.
  • Another, roller 14 parallel to roller 13 is located on a carriage 15, which is displaceable along the lever arm 11 '.
  • the carriage 15 moves the roller 14 against the roller 13, so that the end the packaging material web 9 'is clamped. (Instead of the sliding one Roll 14 can also be brought into engagement with the roll 13 Gripper may be provided.)
  • the Circular cylinder segment 21 carries a friction roller 23 axially parallel to Axis 19, while the counter element 22 is a partially cylindrical counter surface 24 bears against the friction roller 23.
  • the counter element 22 has an outward peripheral surface 22 'corresponding to one Circular cylinder circumferential section, which engages between the circular cylinder segment 21 and counter element 22, the peripheral surface in the form of a circular cylinder peripheral portion the former continues, i.e. that both peripheral surfaces run with the same radius to axis 19.
  • the counter element 22 has adjacent to the counter surface 24 a slightly less than semi-circular recess on average 25, which has a segment-shaped, in particular semicircular, section Holders 26 rotatably with respect to the counter element 22.
  • a knife 27 for example a perforation knife, attached, which is released by turning the holder accordingly (see Fig. 5). With a corresponding rotation of the holder 26, it closes one between the circular cylinder segment 21 and the counter element 22 wedge-shaped gap.
  • a lever-shaped loop former 28 is provided, the pivotable about an axis 29 and at its free end with a baffle plate 30 (or a deflection roller) protruding at right angles is provided.
  • a gluing head 32 is provided which extends into the area the loop of the packaging material web formed by the loop former 28 9 'is retractable in order to have several glue beads, for example Hot glue caterpillars to apply.
  • a rotating knife 33 is provided to the Cut the web of packaging material 9 '' in front of the splicer.
  • the rotating Knife 33 is at the same peripheral speed as the web speed the packaging material web 9 '' rotatable.
  • the knife 33 is on a circular arc into the path of the packaging material path 9 '' at the same time rotatable around its axis. (Instead, one with one standing knives interacting, perpendicular to the packaging material web 9 '' movable knife can be used.)
  • the circular cylinder segment is first 21 pivoted away from the counter element 22 such that the web material gripper 11, which rests with its roller 13 on the bobbin 3 ', between can swing these two parts through without hindrance. If the packaging material web 9 'is clamped between the rollers 13, 14 is, the web material gripper 11 sinks down between the circular cylinder segment 21 and the counter element 22 therethrough. The packaging material web 9 'then runs over the edge located at the top right in FIG. 3 of the circular cylinder segment 21.
  • the circular cylinder segment 21 pivots in Direction towards the counter element 22, so that the packaging material web 9 ' is pinched between the latter two, between the friction roller 23 and its counter surface 24. Furthermore, the Packaging material web 9 'between part of the flat section of the in Section of semicircular holder 26 and a flat counter surface 35 am Circular cylinder segment 21 (see FIG. 4) are additionally clamped, however can be some air here.
  • the loop former 28 now swings into the path of the Packaging material web 9 'and causes the formation of a loop.
  • the glue head 32 then moves into the loop and applies several glue beads on the packaging material web 9 '(alternatively it can also be a head 32, one on both sides adhesive strips or double-sided adhesive dots).
  • the disc 20 rotates with the circular cylinder segment 21 and the counter element 22 and the clamped in between Packing material web 9 'in the direction of the pressure rollers 31', 31 '' and thus in the direction of the packaging material web 9 ′′.
  • the glued Packaging material web 9 ' is thus applied to the first pressure roller 31' the packaging material web 9 '' pressed and connected to it.
  • the gluing is preferably carried out so that a first Glue bead applied practically immediately adjacent to the holder 26 becomes. Then the holder 26 is rotated against the transport direction and with a portion adjacent to the friction roller 23 in one corresponding recess 36 received in the circular cylinder element 21. Thereby becomes a small section of the packaging material web carrying the first glue bead 9 'in the wedge-shaped gap thus formed between Circular cylinder segment 21 and counter element 22 drawn and therefore initially not glued to the packaging material web 9 ''.
  • the circular cylinder segment 21 and its counter element 22 are by rotating the disc 20 from the web of the spliced packaging material web 9 'unscrewed, the same happens with the loop former 28, so that the packaging material web 9 'now over the Pressure rollers 31 ', 31' 'runs.
  • the splicing can thus take place at full transport speed the packaging material web 9 '' and thus at full packaging speed the cigarette packaging machine. Furthermore is the splicer for different materials of packaging material (Paper, foil, cardboard, composite material, etc.).
  • the remaining bobbin core can be in the upper position 4 removed and a new bobbin 3 'are arranged.
