Definitions
- the present invention relates to a packing method and unit for producing an outer container of a hinged-lid, slide-open package of smoking articles.
- Rigid, hinged-lid packets of cigarettes are currently the most widely marketed, by being easy to produce and easy and practical to use, and by effectively protecting the cigarettes inside.
- a rigid, slide-open packet of cigarettes comprises an inner container, which houses a foil-wrapped group of cigarettes and is housed inside an outer container to slide, with respect to the outer container, between a closed configuration, in which the inner container is inserted inside the outer container, and an open configuration, in which the inner container is expelled from the outer container.
- a rigid, hinged-lid, slide-open packet of cigarettes has also been proposed in which the inner container (or outer container) has a hinged lid, which rotates between a closed position and an open position closing and opening an open top end of the inner container.
- the lid has a connecting tab connected at one end to the lid, and at the other end to the outer container (or inner container), to 'automatically' rotate the lid (i.e. without the user having to touch the lid) as the inner container slides with respect to the outer container.
- hinged-lid, slide-open packets of cigarettes see e.g. WO 2009/101120 A1 , however, do not permit high output levels (i.e. the number of packets of cigarettes produced per unit of time), especially if a high quality standard is to be maintained.
- known packing machines for producing hinged-lid, slide-open packets of cigarettes are extremely slow-operating and only suitable for producing limited special series lots.
- Number 1 in Figures 1 and 2 indicates as a whole a rigid, slide-open packet of cigarettes, which opens in a translatory (linear) movement.
- the Figure 1 packet 1 of cigarettes comprises a wrapped, i.e. foil-wrapped group 2 of cigarettes (shown in Figure 2 ).
- Packet 1 of cigarettes also comprises a rigid inner container 3 actually containing the wrapped group 2 of cigarettes; and a rigid outer container 4, which houses inner container 3 to allow inner container 3 to slide in a translatory movement, with respect to outer container 4, between a closed configuration ( Figure 1 ), in which inner container 3 is inserted fully inside outer container 4, and an open configuration ( Figure 2 ), in which inner container 3 is expelled from outer container 4 to allow access to wrapped group 2 of cigarettes.
- inner container 3 is parallelepiped-shaped, and comprises a bottom wall 5; an open top end 6 opposite bottom wall 5; a front wall 7 and rear wall 8 opposite and parallel to each other; and two parallel lateral walls 9 interposed between walls 7 and 8.
- outer container 4 has an open top end 10; and a lid 11 hinged to outer container 4 along a hinge 12 to rotate, with respect to outer container 4, between an open position ( Figures 2 , 3 and 4 ) and a closed position ( Figure 1 ) respectively opening and closing open top end 10 of outer container 4 and, at the same time, also open top end 6 of inner container 3.
- Outer container 4 is parallelepiped-shaped, and comprises a bottom wall 13 opposite open top end 10; a front wall 14 and rear wall 15 opposite and parallel to each other; and two parallel lateral walls 16 interposed between walls 14 and 15.
- Lid 11 comprises a top wall 17 which closes open top end 10 of outer container 4 (and, at the same time, open top end 6 of inner container 3) when lid 11 is closed.
- Top wall 17 of lid 11 is 'flat' (i.e. is formed from one cardboard panel or a number of compacted cardboard panels, and is therefore solid). When lid 11 is closed, top wall 17 of lid 11 is flush with the top edges of walls 14, 15 and 16 of outer container 4.
- rear wall 8 of inner container 3 is connected to top wall 17 of lid 11 by a connecting tab 20 to rotate lid 11 'automatically' (i.e. without the user having to touch lid 11) as inner container 3 slides with respect to outer container 4.
- connecting tab 20 connecting top wall 17 of lid 11 mechanically to rear wall 8 of inner container 3, inner container 3, as it slides with respect to outer container 4 from the closed to the open configuration, pushes lid 11 from the closed to the open position 'automatically' (i.e. without the user having to touch lid 11); and similarly, as inner container 3 slides with respect to outer container 4 from the open to the closed configuration, lid 11 is drawn by inner container 3 from the open to the closed position 'automatically' (i.e.
- connecting tab 20 is connected seamlessly to lid 11, and is glued to rear wall 8 of inner container 3.
- lateral wall 16 of outer container 4 has a through window 21 allowing access to underlying lateral wall 9 of inner container 3 facing lateral wall 16 of outer container 4, to exert thrust on inner container 3 to move it between the closed and open configurations.
- the user holds outer container 4 with one hand and, with the thumb of the same hand, pushes on lateral wall 9 of inner container 3 through window 21 in lateral wall 16 of outer container 4, to exert thrust on inner container 3 and slide it with respect to outer container 4.
- Containers 3 and 4 of the Figure 1-5 packet 1 of cigarettes are formed from corresponding blanks 22 and 23 as shown in Figures 6 and 7 .
- each blank 22, 23 comprises a number of parts, which are indicated, where possible, using the same reference numbers, with superscripts, as for the corresponding walls of respective container 3, 4.
- inner blank 22 has two longitudinal fold lines 24, and a number of transverse fold lines 25 which define, between the two longitudinal fold lines 24, a panel 7' forming front wall 7 of inner container 3; a panel 5' forming bottom wall 5 of inner container 3; and a panel 8' forming rear wall 8 of inner container 3.
- Panel 8' is connected along a transverse fold line 25 to a reinforcing panel 8", in turn connected along a transverse fold line 25 to a further reinforcing panel 8"'.
- Reinforcing panels 8" and 8"' are folded 180° about respective transverse fold lines 25 and glued onto an inner surface of panel 8' to thicken (reinforce) rear wall 8.
- a different embodiment, not shown, has no reinforcing panels 8" and 8"'.
- Panel 7' has two lateral wings 9', which form respective outer portions of lateral walls 9, are located on opposite sides of panel 7', and are separated from panel 7' by longitudinal fold lines 24.
- Panel 8' has two lateral wings 9", which are glued to corresponding wings 9', form respective inner portions of lateral walls 9, are located on opposite sides of panel 8', and are separated from panel 8' by longitudinal fold lines 24.
- Each lateral wing 9" of panel 8' has a tab 26 separated from respective lateral wing 9" by a transverse fold line 25.
- outer blank 23 has two longitudinal fold lines 27, and a number of transverse fold lines 28 which define, between the two longitudinal fold lines 27, a panel 17' forming top wall 17 of lid 11; a panel 15' forming rear wall 15 of outer container 4; a panel 13' forming bottom wall 13 of outer container 4; and a panel 14' forming front wall 14 of outer container 4.
- Panel 17' is connected along a transverse fold line 28 to connecting tab 20, which comprises three panels 20', 20", 20"' separated by respective transverse fold lines 28.
- Panel 20' of connecting tab 20 is glued to an inner surface of top wall 17 of lid 11 (i.e. to an inner surface of panel 17'), and panel 20"' of connecting tab 20 is glued to an outer surface of rear wall 8 of inner container 3 (i.e. to an outer surface of panel 8').
- Panel 14' has two lateral wings 16', which form respective outer portions of lateral walls 16, are located on opposite sides of panel 14', and are separated from panel 14' by longitudinal fold lines 27.
- Panel 15' has two lateral wings 16", which are glued to corresponding wings 16', form respective inner portions of lateral walls 16, are located on opposite sides of panel 15', and are separated from panel 15' by longitudinal fold lines 27.
- Each lateral wing 16" of panel 15' has a tab 29 separated from respective lateral wing 16" by a transverse fold line 28.
- FIG 8 shows a schematic of a cigarette packing machine 30 for producing packets 1 of cigarettes.
- Packing machine 30 comprises, in succession, a packing unit 31 for forming wrapped groups 2 of cigarettes; a packing unit 32 for forming inner containers 3 by folding inner blanks 22 about corresponding wrapped groups 2 of cigarettes; a packing unit 33 for forming outer containers 4 (and so completing packets 1 of cigarettes) by folding outer blanks 23 about corresponding inner containers 3; and, finally, a processing unit 34, which receives packets 1 of cigarettes from packing unit 33 and opens (i.e. slides inner container 3 for the first time with respect to outer container 4, to partly expel inner container 3 and so rotate lid 11 into the open position) and closes each packet 1 of cigarettes.
- packing unit 33 comprises a packing conveyor 69 with a number of packing pockets 70, each for housing an outer blank 23 and corresponding inner container 3, and for feeding outer blank 23 and inner container 3 along a packing path P4 extending between an input station S8 and an output station S10.
- Packing unit 33 preferably comprises a packing conveyor (not shown) for partly prefolding outer blanks 23 and feeding the pre-folded outer blanks 23 to packing conveyor 69.
- a prefolded outer blank 23 i.e. as it is fed to packing conveyor 69
- Figure 10 A prefolded outer blank 23 (i.e. as it is fed to packing conveyor 69) is shown in Figure 10 , in which tab 20 is folded 180° (about corresponding transverse fold line 28 connecting tab 20 to panel 17'), panels 20' and 20" are superimposed on the inner surface of panel 17', and panel 20"' contacts inner surface of panel 15'. As stated, only panel 20' is glued to panel 17'.
- a partly prefolded outer blank 23 is fed into a packing pocket 70 so as to further fold outer blank 23.
- an inner container 3 is fed into a packing pocket 70 and onto the previously inserted outer blank 23. More specifically, rear wall 8 of inner container 3 is positioned resting on panel 15' of outer blank 23.
- outer container 4 (formed by folding outer blank 23 about inner container 3) is expelled from packing pocket 70 and fed to processing unit 34.
- a folding device 71 folds tabs 29 of outer blank 23 ninety degrees (about corresponding transverse fold lines 28) with respect to wings 16", and then, by inserting outer blank 23 inside packing pocket 70, folds panel 13' ninety degrees (about corresponding transverse fold line 28), and folds the two wings 16" ninety degrees (about corresponding longitudinal fold lines 27, while panel 17' of outer blank 23 remains coplanar with panel 15').
- tabs 29 are folded 90°, insertion of outer blank 23 inside packing pocket 70 folds panel 13' and the two wings 16" ninety degrees (while panel 17' of outer blank 23 remains coplanar with panel 15').
- a folding device 72 folds panel 17' of outer blank 23 (i.e. lid 11) 90° (about corresponding transverse fold line 28) with respect to panel 15', and at the same time slides inner container 3 axially with respect to outer blank 23 (as explained more clearly below).
- a folding device 73 folds panel 14' ninety degrees (about corresponding transverse fold line 28).
- Folding outer blank 23 is completed at output station S10 as outer container 4 is expelled from packing pocket 70: as outer container 4 is expelled, a folding device 74 folds wings 16' ninety degrees (about corresponding longitudinal fold lines 27) onto wings 16" to form lateral walls 16 of outer container 4.
- a gumming device (not shown) is preferably provided directly upstream from folding device 74 to deposit glue between wings 16' and 16" just before wings 16' are folded.
- packing conveyor 69 is defined by a wheel which rotates in steps about a central horizontal axis of rotation 75, so packing path P4 is circular and extends from input station S8 to output station S10.
- a gumming device 77 Downstream from input station S8 of packing conveyor 69, a gumming device 77 deposits glue between tabs 29 and panel 13' of outer blank 23. Gumming device 77 also deposits glue 78 and glue 79 ( Figure 10 ) onto panel 20"' of connecting tab 20 previously folded onto panel 15' when partly prefolding outer blank 23. Glue 78 and glue 79 glue rear wall 8 of inner container 3 to connecting tab 20 (i.e. to panel 20"' of connecting tab 20) as inner container 3 is fed onto panel 15' of outer blank 23 at feed station S9 of packing conveyor 69.
- folding device 72 folds panel 17' of outer blank 23 (i.e. lid 11) 90° with respect to panel 15', and at the same time slides inner container 3 axially with respect to outer blank 23 (the axial sliding movement of inner container 3 with respect to outer blank 23 can be seen clearly by comparing the position of inner container 3 in Figures 11 and 13 , before lid 11 is folded, and in Figures 12 and 14 , after lid 11 is folded).
- the axial sliding movement of inner container 3 with respect to outer blank 23 as lid 11 is rotated about hinge 12 is the result of inner container 3 (more specifically, rear wall 8 of inner container 3) being connected mechanically to lid 11 (more specifically, to top wall 17 of lid 11) by connecting tab 20. So rotation of lid 11 about hinge 12 always results in a corresponding translatory movement of inner container 3 according to the transmission ratio produced by the mechanics of connecting tab 20 and by the three hinged panels 20', 20", 20"'.
- Folding device 72 is associated with an actuator 80, which rests on front wall 7 of inner container 3 and is movable in two perpendicular directions (more specifically, translates both perpendicular to and parallel to front wall 7 of inner container 3).
- Actuator 80 comprises a suction head 81 ( Figures 13 and 14 ) in which suction can be turned on/off.
- actuator 80 is moved towards inner container 3 to contact front wall 7 of inner container 3.
- suction is activated through suction head 81 to connect suction head 81 mechanically (by suction) to front wall 7 of inner container 3.
- actuator 80 and folding device 72 are moved together (as shown in Figures 13 and 14 ) and in coordinated manner to fold lid 11 and simultaneously slide inner container 3 with respect to outer blank 23: more specifically, actuator 80 is translated parallel to front wall 7 of inner container 3 to push inner container 3 axially (by pushing on front wall 7 of inner container 3), while folding device 72 is rotated about its axis of rotation (coaxial with hinge 12 of lid 11) to rotate lid 11.
- Lid 11 of outer container 4 being connected mechanically to inner container 3 by connecting tab 20, operation of actuator 80 and folding device 72 must be coordinated (i.e. translation of actuator 80 must always correspond to rotation of folding device 72 according to the transmission ratio produced by the mechanics of connecting tab 20) to prevent deformation and/or tearing.
- each packing pocket 70 also clamps (retains) at least panel 15' of outer blank 23 mechanically, to prevent axial movement of panel 15' in the translation direction of inner container 3 when folding lid 11 ninety degrees and as inner container 3 slides.
- gumming device 77 deposits glue 78 and glue 79 simultaneously onto panel 20"' of connecting tab 20 previously folded onto panel 15' when partly prefolding outer blank 23.
- Glue 78 and glue 79 glue rear wall 8 of inner container 3 to connecting tab 20 (i.e. to panel 20"' of connecting tab 20) as inner container 3 is fed onto panel 15' of outer blank 23 at feed station S9 of packing conveyor 69.
- Glue 78 is permanent, drying glue, i.e. a certain length of time after it is deposited, the volatile components of glue 78 evaporate to form a permanent connection that can only be separated by irreparably tearing the connection apart; whereas glue 79 is non-dry, re-stick glue, i.e. even a long time after it is deposited, the characteristics of glue 79 remain unchanged, allowing the glued parts to be separated and stuck back together repeatedly.
- permanent, drying glue 78 is a cold, vinyl-based glue.
- non-dry, re-stick glue 79 is deposited far from a hinge 12' of connecting tab 20 (hinge 12' of connecting tab 20 is defined by the transverse fold line 28 separating panels 20" and 20"'), whereas permanent, drying glue 78 is deposited close to hinge 12' of connecting tab 20, so that, as folding device 72 folds lid 11, non-dry, re-stick glue 79 is subjected to shear (i.e. greater) stress, while permanent, drying glue 78 is subjected to tensile (i.e. less) stress.
- non-dry, re-stick glue 79 is capable of achieving maximum grip much faster (practically instantaneously), it is important that it be subjected to the greater stress; and, similarly, it is important that permanent, drying glue 78 be subjected to less stress, by taking a relatively long time to achieve adequate grip.
- lid 11 only has top wall 17. In other perfectly equivalent embodiments not shown, lid 11 also has other walls (e.g. a front wall, two lateral walls and/or a rear wall).
- connecting tab 20 forms an integral part of outer blank 23 (i.e. is connected seamlessly to lid 11 of outer container 4) and is glued to rear wall 8 of inner container 3.
- connecting tab 20 forms an integral part of inner blank 22 (i.e. is connected seamlessly to inner container 3) and is glued to top wall 17 of lid 11.
- glue 78 and glue 79 are deposited between connecting tab 20 and top wall 17 of lid 11.
- connecting tab 20 comprises three panels 20', 20", 20"' separated by respective transverse fold lines 28.
- connecting tab 20 comprises a different number of (e.g. two or four) panels separated by respective transverse fold lines 28, or comprises one panel with no transverse fold lines 28.
- the packing method and corresponding packing unit 33 described above have numerous advantages, by enabling high-output production of outer containers 4 of packets 1 of cigarettes (i.e. a large number of outer containers 4 per unit of time) while still maintaining a high quality standard.
- actuator 80 accompanying and facilitating the sliding movement of inner container 3 with respect to outer blank 23 as folding device 72 rotates lid 11 through 90°.
- the thrust exerted on inner container 3 to slide it is provided solely by connecting tab 20 and the grip afforded by glue 78 and glue 79.
- glue 78 and glue 79 offer no guarantee of withstanding the mechanical stress involved in transmitting thrust from lid 11 to inner container 3 via connecting tab 20. Without actuator 80, rotation of lid 11 may therefore result in partial failure of the glued joint between connecting tab 20 and rear wall 8 of inner container 3 (thus resulting in undesired movement of inner container 3 with respect to outer blank 23), or in complete failure of the glued joint between connecting tab 20 and rear wall 8 of inner container 3 (thus destroying the mechanism for opening packet 1 of cigarettes). In both cases, packet 1 of cigarettes is irreparably damaged, and must be rejected.
- lid 11 must be folded 90° much more slowly (and even this is not always sufficient), thus greatly reducing the output of the packing process (i.e. the number of packets 1 of cigarettes produced per unit of time).
- actuator 80 the force transmitted by connecting tab 20, when folding lid 11 through 90°, is very little, if not nil, which means lid 11 can be folded 90° much faster, with no risk of (even slightly) damaging the glued joint between connecting tab 20 and rear wall 8 of inner container 3.

Description
- The present invention relates to a packing method and unit for producing an outer container of a hinged-lid, slide-open package of smoking articles.
- In the following description, reference is made, for the sake of simplicity and purely by way of example, to a hinged-lid, slide-open packet of cigarettes.
- Rigid, hinged-lid packets of cigarettes are currently the most widely marketed, by being easy to produce and easy and practical to use, and by effectively protecting the cigarettes inside.
- In addition to the above rigid, hinged-lid packets of cigarettes, rigid slide-open packets have been proposed comprising two partly separable containers, one inserted inside the other. In other words, a rigid, slide-open packet of cigarettes comprises an inner container, which houses a foil-wrapped group of cigarettes and is housed inside an outer container to slide, with respect to the outer container, between a closed configuration, in which the inner container is inserted inside the outer container, and an open configuration, in which the inner container is expelled from the outer container.
- A rigid, hinged-lid, slide-open packet of cigarettes has also been proposed in which the inner container (or outer container) has a hinged lid, which rotates between a closed position and an open position closing and opening an open top end of the inner container. The lid has a connecting tab connected at one end to the lid, and at the other end to the outer container (or inner container), to 'automatically' rotate the lid (i.e. without the user having to touch the lid) as the inner container slides with respect to the outer container.
- Currently used methods of producing hinged-lid, slide-open packets of cigarettes see e.g.
WO 2009/101120 A1 , however, do not permit high output levels (i.e. the number of packets of cigarettes produced per unit of time), especially if a high quality standard is to be maintained. As a result, known packing machines for producing hinged-lid, slide-open packets of cigarettes are extremely slow-operating and only suitable for producing limited special series lots. - It is an object of the present invention to provide a packing method and unit for producing an outer container of a hinged-lid, slide-open package of smoking articles, designed to eliminate the above drawbacks, and which are cheap and easy to implement.
- According to the present invention, there are provided a packing method and unit for producing an outer container of a hinged-lid, slide-open package of smoking articles, as claimed in the accompanying Claims.

Lid 11 comprises atop wall 17 which closes opentop end 10 of outer container 4 (and, at the same time, open top end 6 of inner container 3) whenlid 11 is closed.Top wall 17 oflid 11 is 'flat' (i.e. is formed from one cardboard panel or a number of compacted cardboard panels, and is therefore solid). Whenlid 11 is closed,top wall 17 oflid 11 is flush with the top edges ofwalls - In a preferred embodiment,
rear wall 8 ofinner container 3 is connected totop wall 17 oflid 11 by a connectingtab 20 to rotate lid 11 'automatically' (i.e. without the user having to touch lid 11) asinner container 3 slides with respect to outer container 4. In other words, by means of connectingtab 20 connectingtop wall 17 oflid 11 mechanically torear wall 8 ofinner container 3,inner container 3, as it slides with respect to outer container 4 from the closed to the open configuration, pusheslid 11 from the closed to the open position 'automatically' (i.e. without the user having to touch lid 11); and similarly, asinner container 3 slides with respect to outer container 4 from the open to the closed configuration,lid 11 is drawn byinner container 3 from the open to the closed position 'automatically' (i.e. without the user having to touch lid 11). The user therefore need simply exert sufficient thrust to slideinner container 3 with respect to outer container 4, without having to touchlid 11, which is rotated 'automatically'. Preferably, connectingtab 20 is connected seamlessly tolid 11, and is glued torear wall 8 ofinner container 3. - As shown in
Figures 1, 2 and4 ,lateral wall 16 of outer container 4 has a throughwindow 21 allowing access to underlyinglateral wall 9 ofinner container 3 facinglateral wall 16 of outer container 4, to exert thrust oninner container 3 to move it between the closed and open configurations. In other words, to usepacket 1 of cigarettes, the user holds outer container 4 with one hand and, with the thumb of the same hand, pushes onlateral wall 9 ofinner container 3 throughwindow 21 inlateral wall 16 of outer container 4, to exert thrust oninner container 3 and slide it with respect to outer container 4. -
Containers 3 and 4 of theFigure 1-5 packet 1 of cigarettes are formed fromcorresponding blanks Figures 6 and7 . Among other things, each blank 22, 23 comprises a number of parts, which are indicated, where possible, using the same reference numbers, with superscripts, as for the corresponding walls ofrespective container 3, 4. - With reference to
Figure 6 ,inner blank 22 has twolongitudinal fold lines 24, and a number oftransverse fold lines 25 which define, between the twolongitudinal fold lines 24, a panel 7' formingfront wall 7 ofinner container 3; a panel 5' formingbottom wall 5 ofinner container 3; and a panel 8' formingrear wall 8 ofinner container 3. Panel 8' is connected along atransverse fold line 25 to a reinforcingpanel 8", in turn connected along atransverse fold line 25 to a further reinforcingpanel 8"'. Reinforcingpanels 8" and 8"' are folded 180° about respectivetransverse fold lines 25 and glued onto an inner surface of panel 8' to thicken (reinforce)rear wall 8. A different embodiment, not shown, has no reinforcingpanels 8" and 8"'. - Panel 7' has two lateral wings 9', which form respective outer portions of
lateral walls 9, are located on opposite sides of panel 7', and are separated from panel 7' bylongitudinal fold lines 24. Panel 8' has twolateral wings 9", which are glued to corresponding wings 9', form respective inner portions oflateral walls 9, are located on opposite sides of panel 8', and are separated from panel 8' bylongitudinal fold lines 24. Eachlateral wing 9" of panel 8' has atab 26 separated from respectivelateral wing 9" by atransverse fold line 25. - With reference to
Figure 7 ,outer blank 23 has twolongitudinal fold lines 27, and a number oftransverse fold lines 28 which define, between the twolongitudinal fold lines 27, a panel 17' formingtop wall 17 oflid 11; a panel 15' formingrear wall 15 of outer container 4; a panel 13' formingbottom wall 13 of outer container 4; and a panel 14' formingfront wall 14 of outer container 4. - Panel 17' is connected along a
transverse fold line 28 to connectingtab 20, which comprises threepanels 20', 20", 20"' separated by respectivetransverse fold lines 28. Panel 20' of connectingtab 20 is glued to an inner surface oftop wall 17 of lid 11 (i.e. to an inner surface of panel 17'), andpanel 20"' of connectingtab 20 is glued to an outer surface ofrear wall 8 of inner container 3 (i.e. to an outer surface of panel 8'). - Panel 14' has two lateral wings 16', which form respective outer portions of
lateral walls 16, are located on opposite sides of panel 14', and are separated from panel 14' bylongitudinal fold lines 27. Panel 15' has twolateral wings 16", which are glued to corresponding wings 16', form respective inner portions oflateral walls 16, are located on opposite sides of panel 15', and are separated from panel 15' bylongitudinal fold lines 27. Eachlateral wing 16" of panel 15' has atab 29 separated from respectivelateral wing 16" by atransverse fold line 28. -
Figure 8 shows a schematic of acigarette packing machine 30 for producingpackets 1 of cigarettes.Packing machine 30 comprises, in succession, apacking unit 31 for forming wrappedgroups 2 of cigarettes; apacking unit 32 for forminginner containers 3 by foldinginner blanks 22 about corresponding wrappedgroups 2 of cigarettes; apacking unit 33 for forming outer containers 4 (and so completingpackets 1 of cigarettes) by foldingouter blanks 23 about correspondinginner containers 3; and, finally, aprocessing unit 34, which receivespackets 1 of cigarettes frompacking unit 33 and opens (i.e. slidesinner container 3 for the first time with respect to outer container 4, to partly expelinner container 3 and so rotatelid 11 into the open position) and closes eachpacket 1 of cigarettes. - As shown in
Figure 9 ,packing unit 33 comprises apacking conveyor 69 with a number ofpacking pockets 70, each for housing an outer blank 23 and correspondinginner container 3, and for feeding outer blank 23 andinner container 3 along a packing path P4 extending between an input station S8 and an output station S10. -
Packing unit 33 preferably comprises a packing conveyor (not shown) for partly prefoldingouter blanks 23 and feeding the pre-foldedouter blanks 23 to packingconveyor 69. A prefolded outer blank 23 (i.e. as it is fed to packing conveyor 69) is shown inFigure 10 , in whichtab 20 is folded 180° (about correspondingtransverse fold line 28 connectingtab 20 to panel 17'),panels 20' and 20" are superimposed on the inner surface of panel 17', andpanel 20"' contacts inner surface of panel 15'. As stated, only panel 20' is glued to panel 17'. - At input station S8, a partly prefolded outer blank 23 is fed into a packing
pocket 70 so as to further fold outer blank 23. At a feed station S9 between input station S8 and output station S10, aninner container 3 is fed into a packingpocket 70 and onto the previously inserted outer blank 23. More specifically,rear wall 8 ofinner container 3 is positioned resting on panel 15' of outer blank 23. At output station S10, outer container 4 (formed by folding outer blank 23 about inner container 3) is expelled from packingpocket 70 and fed to processingunit 34. - At input station S8, a
folding device 71folds tabs 29 of outer blank 23 ninety degrees (about corresponding transverse fold lines 28) with respect towings 16", and then, by inserting outer blank 23 inside packingpocket 70, folds panel 13' ninety degrees (about corresponding transverse fold line 28), and folds the twowings 16" ninety degrees (about correspondinglongitudinal fold lines 27, while panel 17' of outer blank 23 remains coplanar with panel 15'). In other words, aftertabs 29 are folded 90°, insertion of outer blank 23 inside packingpocket 70 folds panel 13' and the twowings 16" ninety degrees (while panel 17' of outer blank 23 remains coplanar with panel 15'). Between feed station S9 and output station S10, afolding device 72 folds panel 17' of outer blank 23 (i.e. lid 11) 90° (about corresponding transverse fold line 28) with respect to panel 15', and at the same time slidesinner container 3 axially with respect to outer blank 23 (as explained more clearly below). Directly downstream from foldingdevice 72, afolding device 73 folds panel 14' ninety degrees (about corresponding transverse fold line 28). Folding outer blank 23 is completed at output station S10 as outer container 4 is expelled from packing pocket 70: as outer container 4 is expelled, afolding device 74 folds wings 16' ninety degrees (about corresponding longitudinal fold lines 27) ontowings 16" to formlateral walls 16 of outer container 4. A gumming device (not shown) is preferably provided directly upstream from foldingdevice 74 to deposit glue betweenwings 16' and 16" just before wings 16' are folded. - In a preferred embodiment shown in
Figures 8 and9 , packingconveyor 69 is defined by a wheel which rotates in steps about a central horizontal axis ofrotation 75, so packing path P4 is circular and extends from input station S8 to output station S10. - Upstream from input station S8 of packing
conveyor 69, a gummingdevice 77 deposits glue betweentabs 29 and panel 13' of outer blank 23. Gummingdevice 77 alsodeposits glue 78 and glue 79 (Figure 10 ) ontopanel 20"' of connectingtab 20 previously folded onto panel 15' when partly prefolding outer blank 23.Glue 78 andglue 79 gluerear wall 8 ofinner container 3 to connecting tab 20 (i.e. topanel 20"' of connecting tab 20) asinner container 3 is fed onto panel 15' of outer blank 23 at feed station S9 of packingconveyor 69. - As shown in
Figures 11-14 ,folding device 72 folds panel 17' of outer blank 23 (i.e. lid 11) 90° with respect to panel 15', and at the same time slidesinner container 3 axially with respect to outer blank 23 (the axial sliding movement ofinner container 3 with respect to outer blank 23 can be seen clearly by comparing the position ofinner container 3 inFigures 11 and13 , beforelid 11 is folded, and inFigures 12 and14 , afterlid 11 is folded). The axial sliding movement ofinner container 3 with respect to outer blank 23 aslid 11 is rotated abouthinge 12 is the result of inner container 3 (more specifically,rear wall 8 of inner container 3) being connected mechanically to lid 11 (more specifically, totop wall 17 of lid 11) by connectingtab 20. So rotation oflid 11 abouthinge 12 always results in a corresponding translatory movement ofinner container 3 according to the transmission ratio produced by the mechanics of connectingtab 20 and by the three hingedpanels 20', 20", 20"'. -
Folding device 72 is associated with anactuator 80, which rests onfront wall 7 ofinner container 3 and is movable in two perpendicular directions (more specifically, translates both perpendicular to and parallel tofront wall 7 of inner container 3).Actuator 80 comprises a suction head 81 (Figures 13 and14 ) in which suction can be turned on/off. When a packingpocket 70 containing an outer blank 23 and respectiveinner container 3reaches folding device 72,actuator 80 is moved towardsinner container 3 to contactfront wall 7 ofinner container 3. Onceactuator 80 is positioned contactingfront wall 7 ofinner container 3, suction is activated throughsuction head 81 to connectsuction head 81 mechanically (by suction) tofront wall 7 ofinner container 3. - Once suction is activated through
suction head 81,actuator 80 andfolding device 72 are moved together (as shown inFigures 13 and14 ) and in coordinated manner to foldlid 11 and simultaneously slideinner container 3 with respect to outer blank 23: more specifically,actuator 80 is translated parallel tofront wall 7 ofinner container 3 to pushinner container 3 axially (by pushing onfront wall 7 of inner container 3), while foldingdevice 72 is rotated about its axis of rotation (coaxial withhinge 12 of lid 11) to rotatelid 11.Lid 11 of outer container 4 being connected mechanically toinner container 3 by connectingtab 20, operation ofactuator 80 andfolding device 72 must be coordinated (i.e. translation ofactuator 80 must always correspond to rotation of foldingdevice 72 according to the transmission ratio produced by the mechanics of connecting tab 20) to prevent deformation and/or tearing. - It is important to note that, besides housing outer blank 23 and corresponding
inner container 3, each packingpocket 70 also clamps (retains) at least panel 15' of outer blank 23 mechanically, to prevent axial movement of panel 15' in the translation direction ofinner container 3 when foldinglid 11 ninety degrees and asinner container 3 slides. - As stated, gumming
device 77deposits glue 78 andglue 79 simultaneously ontopanel 20"' of connectingtab 20 previously folded onto panel 15' when partly prefolding outer blank 23.Glue 78 andglue 79 gluerear wall 8 ofinner container 3 to connecting tab 20 (i.e. topanel 20"' of connecting tab 20) asinner container 3 is fed onto panel 15' of outer blank 23 at feed station S9 of packingconveyor 69.Glue 78 is permanent, drying glue, i.e. a certain length of time after it is deposited, the volatile components ofglue 78 evaporate to form a permanent connection that can only be separated by irreparably tearing the connection apart; whereasglue 79 is non-dry, re-stick glue, i.e. even a long time after it is deposited, the characteristics ofglue 79 remain unchanged, allowing the glued parts to be separated and stuck back together repeatedly. Preferably, permanent, dryingglue 78 is a cold, vinyl-based glue. - In a preferred embodiment, non-dry,
re-stick glue 79 is deposited far from a hinge 12' of connecting tab 20 (hinge 12' of connectingtab 20 is defined by thetransverse fold line 28separating panels 20" and 20"'), whereas permanent, dryingglue 78 is deposited close to hinge 12' of connectingtab 20, so that, as foldingdevice 72folds lid 11, non-dry,re-stick glue 79 is subjected to shear (i.e. greater) stress, while permanent, dryingglue 78 is subjected to tensile (i.e. less) stress. Because non-dry,re-stick glue 79 is capable of achieving maximum grip much faster (practically instantaneously), it is important that it be subjected to the greater stress; and, similarly, it is important that permanent, dryingglue 78 be subjected to less stress, by taking a relatively long time to achieve adequate grip. - In the embodiment shown in the drawings,
lid 11 only hastop wall 17. In other perfectly equivalent embodiments not shown,lid 11 also has other walls (e.g. a front wall, two lateral walls and/or a rear wall). - In the embodiment shown in the drawings, connecting
tab 20 forms an integral part of outer blank 23 (i.e. is connected seamlessly tolid 11 of outer container 4) and is glued torear wall 8 ofinner container 3. In an alternative embodiment not shown and not part of the present invention, connectingtab 20 forms an integral part of inner blank 22 (i.e. is connected seamlessly to inner container 3) and is glued totop wall 17 oflid 11. Obviously, in this embodiment,glue 78 andglue 79 are deposited between connectingtab 20 andtop wall 17 oflid 11. - In the embodiment shown in the drawings, connecting
tab 20 comprises threepanels 20', 20", 20"' separated by respective transverse fold lines 28. In alternative embodiments not shown and not part of the present invention, connectingtab 20 comprises a different number of (e.g. two or four) panels separated by respectivetransverse fold lines 28, or comprises one panel with no transverse fold lines 28. - The packing method and
corresponding packing unit 33 described above have numerous advantages, by enabling high-output production of outer containers 4 ofpackets 1 of cigarettes (i.e. a large number of outer containers 4 per unit of time) while still maintaining a high quality standard. This is made possible byactuator 80 accompanying and facilitating the sliding movement ofinner container 3 with respect to outer blank 23 as foldingdevice 72 rotateslid 11 through 90°. In fact, withoutactuator 80, the thrust exerted oninner container 3 to slide it is provided solely by connectingtab 20 and the grip afforded byglue 78 andglue 79. At this stage, however, the grip afforded byglue 78 andglue 79 is far from nominal, which can only be achieved after they set completely, soglue 78 andglue 79 offer no guarantee of withstanding the mechanical stress involved in transmitting thrust fromlid 11 toinner container 3 via connectingtab 20. Withoutactuator 80, rotation oflid 11 may therefore result in partial failure of the glued joint between connectingtab 20 andrear wall 8 of inner container 3 (thus resulting in undesired movement ofinner container 3 with respect to outer blank 23), or in complete failure of the glued joint between connectingtab 20 andrear wall 8 of inner container 3 (thus destroying the mechanism for openingpacket 1 of cigarettes). In both cases,packet 1 of cigarettes is irreparably damaged, and must be rejected. - Without the aid of
actuator 80, to avoid damaging the glued joint between connectingtab 20 andrear wall 8 ofinner container 3,lid 11 must be folded 90° much more slowly (and even this is not always sufficient), thus greatly reducing the output of the packing process (i.e. the number ofpackets 1 of cigarettes produced per unit of time). Usingactuator 80, on the other hand, the force transmitted by connectingtab 20, when foldinglid 11 through 90°, is very little, if not nil, which meanslid 11 can be folded 90° much faster, with no risk of (even slightly) damaging the glued joint between connectingtab 20 andrear wall 8 ofinner container 3.
