  • Patent Application EP2017198A1 describes a fan-open rigid packet of cigarettes (comprising at least two inner containers held together by the outer container).
  • the only characteristic common to all these last-generation rigid packets of cigarettes is that they are made from two different blanks folded one after the other (i.e. the inner blank is first folded about the group of cigarettes, and the outer blank is then folded about the folded inner blank).
  • the most critical brand-change part i.e. when switching from one type of rigid packet of cigarettes to another
  • the transfer unit which transfers the inner containers from the first packing unit to the second packing unit, and on which the inner containers are oriented and/or grouped specifically, according to the type of rigid packet of cigarettes.
  • Patent Application WO2008101571A1 describes the closest prior art, via a packing machine for producing rigid packets of cigarettes, each comprising an inner cursor folded about a wrapped group of cigarettes; and an outer blank folded about the wrapped group of cigarettes and the inner cursor.
  • the packing machine comprises: a first packing unit for folding the inner cursors about the wrapped groups of cigarettes; a second packing unit for folding the outer blanks about the wrapped groups of cigarettes and the inner cursors; and a transfer unit, which receives the wrapped groups of cigarettes with the inner cursors from the first packing unit at an input station, feeds them to the second packing unit at an output station, and performs a single orienting operation on them at a manipulating station between the input station and the output station.
  • the transfer unit comprises a single conveyor line, which feeds a succession of wrapped groups of cigarettes with inner cursors along a path between the input station and the output station; and the manipulating station comprises an orienting wheel with peripheral pockets and mounted to rotate about an axis of rotation perpendicular to the path.

  • inner container 3 is parallelepiped-shaped, and has a bottom wall 5; a top wall 6; two opposite parallel major lateral walls 7; and two parallel minor lateral walls 8a, 8b interposed between major lateral walls 7.
  • top wall 6 has an extraction opening 9 also extending over parts of major lateral walls 7, and which, when inner container 3 is in the open position, is located outside outer container 4 to permit withdrawal of the cigarettes (not shown) from inner container 3 once group 2 is unwrapped by the user.
  • a retaining tab 10 is cut from each major lateral wall 7, close to minor lateral wall 8b, and projects outwards of inner container 3 from the edge between major lateral wall 7 and minor lateral wall 8b; four longitudinal edges are defined between major lateral walls 7 and minor lateral walls 8; and eight transverse edges are defined between walls 7, 8 and walls 5, 6.
  • outer container 4 is also parallelepiped-shaped, and has a bottom wall 11; a top wall 12; two opposite parallel major lateral walls 13; one minor lateral wall 14; and an opening 15 opposite minor lateral wall 14 and through which inner container 3 slides.
  • a retaining tab 16 is connected to the edge of each major lateral wall 13 bounding opening 15, projects inwards of outer container 4 from major lateral wall 13, and, as inner container 3 is extracted,, engages a corresponding retaining tab 10 on inner container 3 to limit travel of inner container 3 and prevent it from detaching completely from outer container 4.
  • Two longitudinal edges are defined between major lateral walls 13 and minor lateral wall 14; and six transverse edges are defined between walls 13, 14 and walls 11, 12.

  • packing unit 20 comprises a group-forming conveyor 25 for forming groups 26 of cigarettes, and having a number of pockets, each for receiving a group 26 of cigarettes from the outlet of a hopper; and a packing conveyor 27 having two straight, parallel, superimposed packing lines, on which sheets 28 of packing material, cut off a continuous strip, are folded about groups 26 of cigarettes to form wrapped groups 2 of cigarettes.
  • packing unit 20 comprises a transfer wheel 29 for receiving wrapped groups 2 of cigarettes from packing conveyor 27; a packing wheel 30, which receives wrapped groups 2 of cigarettes from transfer wheel 29, and folds blanks 17 about wrapped groups 2 of cigarettes to form inner containers 3; and a drying conveyor 31 having two straight, parallel, superimposed drying lines for receiving and feeding inner containers 3 from packing wheel 30 to input station 23 of transfer unit 22.
  • transfer unit 22 transfers inner containers 3 from input station 23 to output station 24, and orients (in another embodiment, also groups) inner containers at four manipulating stations 32-35 arranged in series between input station 23 and output station 24.
  • transfer unit 22 comprises four manipulating stations 32-35 that can be fully or even partly activated or deactivated individually, depending on the desired orientation and/or grouping of inner containers 3.

  • transfer unit 22 comprises two parallel, superimposed horizontal conveyor lines, each of which feeds a succession of inner containers 3 - preferably in steps (i.e. in a cyclically alternating stop-go movement) - along a straight path P between input station 23 and output station 24.
  • manipulating stations 33 and 34 are activated in the Figure 11 and 12 embodiment. More specifically, and as explained below, manipulating station 33 performs a 180° rotation about a vertical axis of rotation perpendicular to path P, and manipulating station 34 performs, simultaneously, a further 180° rotation about a vertical axis of rotation perpendicular to path P, and a 90° rotation about a horizontal axis of rotation perpendicular to path P.
