Definitions

  • the present invention relates to a packer machine and a wrapping method to produce a rigid pack for smoking articles with a sealed inner wrap.
  • the present invention finds advantageous application for manufacturing a rigid pack of cigarettes with a hinged lid and containing a group of cigarettes, to which the following disclosure will make explicit reference without thereby losing generality.
  • Rigid packs of cigarettes with a hinged lid are the most popular packs of cigarettes currently on the market as they are simple to manufacture, are easy and practical to use and offer good protection to the cigarettes contained on the inside thereof.
  • a rigid pack of cigarettes with a hinged lid comprises a wrap formed by a group of cigarettes wrapped in a wrapping sheet and a rigid outer casing that houses the wrap on the inside thereof.
  • the outer casing is formed by a cup-shaped container, which houses the group of cigarettes and has an open upper end, and a lid, which is also cup-shaped and is hinged to the container to rotate, relative to the container, between an open position and a closed position of the open end.
  • a traditional pack of cigarettes the group of cigarettes is wrapped in a glue-free rectangular foil wrap.
  • a sealed (waterproof) wrap formed by a wrapping sheet made of waterproof and heat-sealable material with a cigarette pull-out opening, which is closed by a reusable closing label.
  • cigarette inner wraps having " fin folds" are illustrated in the following documents: WO2015128812 , WO2014013479A1 , WO2011009520 , WO2011110272 , EP1686060A1 , US4789060A1 , GB1471086A1 , and US3948389A1 .
  • the patent application EP3222532A1 describes a packer machine to produce a rigid pack of cigarettes with a sealed inner wrap and comprising: a first wrapping unit that forms the inner wrap around the group of smoking articles by folding a wrapping sheet, a second wrapping unit that forms the outer container around the inner wrap by folding a blank, and a positioning unit that receives the inner wrap from the first wrapping unit in an input station where the article is oriented according to an input plane, transfers the inner wrap to the second wrapping unit in an output station where the article is oriented according to an output plane oriented differently from the input plane, and comprises a positioning drum which is rotatable around a rotation axis and supports a parallelepiped-shaped pocket which moves along a positioning path between the input station and the output station .
  • the patent application EP3725690A1 describes a packer machine to produce a rigid pack of cigarettes with a traditional (namely, unsealed) wrap.
  • the object of the present invention is to provide a packer machine and a wrapping method to produce a rigid pack for smoking articles with a sealed inner wrap, which packer machine and wrapping method allow to obtain a high quality pack (namely, having extremely precise and squared off folds) even when operating at a high production speed (measured as packs of cigarettes produced in a unit of time) and at the same time minimize the overall dimensions while offering high accessibility to all parts.
  • a packer machine and a wrapping method to produce a rigid pack for smoking articles with a sealed inner wrap are provided, as claimed in the appended claims.
  • number 1 denotes as a whole a rigid pack of cigarettes with a hinged lid.
  • the pack 1 of cigarettes comprises a cup-shaped outer container 2 made of cardboard or rigid paperboard and a sealed wrap 3 (illustrated in Figure 3 ) housed inside the container 2.
  • the outer container 2 has an open upper end and is provided with a lid 4, which is cup-shaped and is hinged to the outer container 2 along a hinge 5 (illustrated in Figure 2 ) so as to rotate, relative to the outer container 2, between an open position (not illustrated) and a closed position (illustrated in Figures 1 and 2 ) of the open upper end.
  • a lid 4 which is cup-shaped and is hinged to the outer container 2 along a hinge 5 (illustrated in Figure 2 ) so as to rotate, relative to the outer container 2, between an open position (not illustrated) and a closed position (illustrated in Figures 1 and 2 ) of the open upper end.
  • the sealed wrap 3 (illustrated in Figure 3 ) encloses a group 6 of cigarettes (partially illustrated in Figure 4 ) with a parallelepiped shape; each cigarette is provided with a filter 7 and therefore the group 6 of cigarettes has an upper wall formed by the circular ends (tips) of the filters 7 and a lower wall, opposite the upper wall, formed by the circular ends (tips) of the tobacco rods.
  • the sealed wrap 3 has a cigarette pull-out opening 8 at the top and in front, which is delimited by a pre-weakened tear-off line, is closed by a reusable closing label 9 and involves a portion of a front wall of the sealed wrap 3 and a portion of an upper wall of the sealed wrap 3.
  • the closing label 9 is fixed to the cigarette sealed wrap 3 by means of re-stick glue that does not dry, which is applied to the lower surface of the closing label 9 and is arranged all around the pull-out opening 8 so as to allow the closing label 9 to be partially separated several times from the sealed wrap 3 and then re-fixed to the sealed wrap 3.
  • the sealed wrap 3 is devoid of the pull-out opening 8 and of the relative closing label 9 and has a removable upper portion, which is separated from the rest of the sealed wrap 3 by a pre-weakened tear-off line to be removed by tearing at the first opening of the sealed wrap 3; in this embodiment, the sealed wrap 3 is preferably provided with a tear-off opening tape to facilitate breakage of the sealed wrap 3 along the pre-weakened line.
  • the sealed wrap 3 is obtained by folding a wrapping sheet 10 (illustrated in Figure 6 ), which has a rectangular shape, comprises at least one layer of air-impermeable and heat-sealable plastic material, and is folded directly around the group 6 of cigarettes in order to be in direct contact with the cigarettes.
  • a wrapping sheet 10 illustrated in Figure 6
  • the shape of the sealed wrap 3 is stabilized by performing a heat-sealing of the overlapping portions of the wrapping sheet 10.
  • the wrapping sheet 10 Before folding the wrapping sheet 10 around the group 6 of cigarettes, the wrapping sheet 10 is pre-cut to define the pull-out opening 8; subsequently, the closing label 9 with glue on the lower part is applied to the wrapping sheet 10, that is, provided on its lower surface with the re-stick glue which inside the pull-out opening 8 determines the permanent gluing of the inner portion of the wrapping sheet 10 to the closing label 9 and on the outside of the pull-out opening 8 determines a re-stick gluing of the wrapping sheet 10 to the closing label 9.
  • the sealed pack 4 could comprise a "U"-shaped reinforcement element 11, which is made of cardboard or rigid paperboard and is arranged inside the sealed wrap 3 in contact with the group 6 of cigarettes.
  • the function of the reinforcement element 11 is to give greater rigidity and greater stability of shape to the sealed wrap 3 so as to prevent the sealed wrap 3 from collapsing in on itself after having pulled out a part of the cigarettes contained in the sealed wrap 3, making it difficult to pull out the remaining cigarettes and in particular making the opening and subsequent reclosing of the closing label 9 extremely complicated.
  • a further function of the reinforcement element 11 is to provide mechanical protection to the cigarettes during the folding of the wrapping sheet 10, a mechanical and thermal protection to the cigarettes during the heat-sealing of the overlapping portions of the wrapping sheet 10, and a mechanical protection to the cigarettes during handling of the sealed wrap 3.
  • the reinforcement element 11 comprises a front wall 12 arranged in contact with the cylindrical side walls of the cigarettes of the group 6 of cigarettes, two side walls 13 arranged on opposite sides of the front wall 12 in contact with the cylindrical side walls of the cigarettes of the group 6 of cigarettes, a lower wall 14 arranged in contact with the tips of the cigarettes of the group 6 of cigarettes (namely, arranged in contact with the lower wall of the group 6 of cigarettes), and a (small) rear wall 15 arranged in contact with the cylindrical side walls of the cigarettes of the group 6 of cigarettes on the opposite side of the front wall 12.
  • the front wall 12 has an upper flare 16, which is arranged in the area of the cigarette pull-out opening 8 so that the front wall 12 does not overlap the cigarette pull-out opening 8.
  • the forming of a sealed wrap 3 provides for initially forming a group 6 of cigarettes and then folding a reinforcement element 11 around the group 6 of cigarettes. Subsequently and as illustrated in Figures 9-16 , the wrapping sheet 10 is folded around the group 6 of cigarettes coupled to the reinforcement element 11.
  • Figures 9-16 illustrate the folding steps of the wrapping sheet 10 around the group 6 of cigarettes that presents: two larger side walls that are opposite to one another and are formed by the cylindrical side walls of the cigarettes, two smaller side walls that are opposite to one another and are formed by the cylindrical side walls of the cigarettes, an upper wall formed by the ends of the filters 7, and a lower wall formed by the ends (tips) of the tobacco rods.
  • the group 6 of cigarettes is coupled to the unfolded wrapping sheet 10 by bringing the upper wall (on the side of the filters 7) of the group 6 of cigarettes into contact with the wrapping sheet 10 ( Figure 9 ); subsequently, the wrapping sheet is folded in a "U" shape around the group 6 of cigarettes ( Figure 10 ) so that the wrapping sheet 10 folded in a "U” shape is arranged in the area of the upper wall and of the two larger side walls of the group 6 of cigarettes and has two ends 17 and 18 that are parallel to the larger side walls and protrude from the larger side walls (namely, they continue beyond the larger side walls); it is important to note that the wrapping sheet 10 is fed asymmetrically in front of the group 6 of cigarettes (namely, the wrapping sheet 10 is placed asymmetrically against the upper wall of the group 6 of cigarettes) to define the two ends 17 and 18, which both protrude from the group 6 of cigarettes and have a different length (namely, the end 17 is longer than the end 18 and the difference in length between the end 17 and the end 18 is equal to the width of the lower
  • the end 17 is parallel to a first larger side wall of the group 6 of cigarettes and protrudes from the first lower wall of the group 6 of cigarettes continuing beyond the larger side wall; similarly, the end 18 is parallel to a second larger side wall of the group 6 of cigarettes and protrudes from the lower wall of the group 6 of cigarettes continuing beyond the second larger side wall.
  • the end 17 is folded by 90° relative to the first larger side wall of the group 6 of cigarettes and against the lower wall of the group 6 of cigarettes and, at the same time, a final part of the end 17 is folded by 90° to give the end 17 an "L" shape and then arrange the final part of the end 17 parallel and resting on the end 18 (which does not undergo, in this step, any type of folding, i.e., it remains parallel to the second larger side wall) giving the wrapping sheet 10 a tubular shape; in other words, at the same time (namely, with the same folding action) the end 17 is folded by 90° at two distinct points: a first folding by 90° around the edge between the first larger side wall and the lower wall and a second folding at the edge between the second larger side wall and the lower wall (namely, near the end 18) so as to give the end 17 an "L" shape and to rest the final part of the end 17 against the end 18.
  • the overlapping and heat-sealed ends 17 and 18 are folded by 180° against the second larger side wall of the group 6 of cigarettes (as illustrated in Figure 14 ) and with the interposition of part of wrapping sheet 10.
  • the two ends 17 and 18 have the same length, are both folded in an "L" shape against the lower wall of the group 6 of cigarettes to form the sealing fin 19, and finally the sealing fin 19 (which is initially located at the centre of the lower wall of the group 6 of cigarettes) is folded by 90° against the lower wall of the group 6 of cigarettes.
  • the two open side edges of the wrapping sheet 10 (which has a tubular shape around the group 6 of cigarettes) are closed by means of the so-called "soap-bar fold " which for each side edge provides for: folding two smaller flaps against the smaller side wall of the group 6 of cigarettes (in fact the smaller flap arranged in the area of the upper wall of the group 6 of cigarettes is folded beforehand when the wrapping sheet 10, for the first time, comes into contact with the group 6 of cigarettes and folds in a "U shape around the group 6 of cigarettes), folding one larger flap against the smaller side wall of group 6 of cigarettes and over the two smaller flaps previously folded, and finally folding the other larger flap against the smaller side wall of the group 6 of cigarettes and above the two smaller flaps and the larger flap previously folded.
  • the pack 1 of cigarettes comprises, furthermore, a rigid collar 20, which is connected (by gluing) folded in a "U" shape inside the outer container 2 to partially protrude outside the open upper end of the outer container 2 and to engage a corresponding inner surface of the lid 4 when the lid 4 is arranged in the closed position.
  • the outer container 2 and the lid 4 are obtained by folding a blank 21 of a conventional type.
  • number 22 denotes, as a whole, a packer machine which is designed to manufacture the pack 1 of cigarettes described above and operates with intermittent motion (namely, a motion which provides for a cyclical alternation of motion steps and stop steps).
  • the packer machine 22 comprises a forming unit A where the groups 6 of cigarettes are formed in succession, a wrapping unit B where a respective wrapping sheet 10 is wrapped around each group 6 of cigarettes to obtain a sealed wrap 3, and a wrapping unit C where a collar 20 and a blank 21 are wrapped around each sealed wrap 3 so as to obtain an outer container 2 provided with the lid 4.
  • the forming unit A for the groups 6 of cigarettes comprises a hopper 23 provided with three output mouths 24 for simultaneously feeding three groups 6 of cigarettes to three respective pockets 25 of a forming conveyor 26 which supports a plurality of pockets 25.
  • the forming conveyor 26 comprises an annular-shaped conveyor belt, which is wound around two end pulleys (one of which is motorized), supports the pockets 25 and moves in step so as to cyclically move the pockets 25 along a forming path P1.
  • the forming path P1 develops between an input station S1 where each group 6 of cigarettes is pulled out from an output mouth 24 of the hopper 23 and enters a corresponding pocket 25 and a transfer station S2 where each group 6 of cigarettes is pulled out from the corresponding pocket 25.
  • a control station where the completeness of each group 6 of cigarettes and the correct filling of the cigarette tips of each group 6 of cigarettes is optically checked, and a subsequent discard station, where any defective group 6 of cigarettes signalled by the control station is discarded (for example by means of a mechanical or pneumatic expulsion from the respective pocket 25), are arranged along the forming conveyor 26.

  • the wrapping path P2 extends from the transfer station S2 where the wrapping conveyor 27 pull outs each group 6 of cigarettes from the corresponding pocket 25 of the forming conveyor 26, passes through a feeding station S3 where each group 6 of cigarettes couples to a corresponding wrapping sheet 10 that folds in a "U" shape around the group 6 of cigarettes, and ends in a transfer station S4 where each sealed wrap 3 being formed (namely, only partially formed) leaves the wrapping conveyor 27.
  • the wrapping conveyor 27 comprises an annular-shaped conveyor belt 28, which is wound around two end pulleys (one of which is motorized) and supports a plurality of pushers, each of which is connected to the conveyor belt 28 by means of a support column (narrower than the pusher) and is designed to engage the upper wall (formed by the ends of the filters 7) of a corresponding group 6 of cigarettes to push the group 6 of cigarettes along the wrapping path P2.
  • the wrapping conveyor 27 comprises a horizontal channel which is delimited at least at the bottom and laterally (preferably also at the top in its initial part), is arranged along the wrapping path P2, and contains each group 6 of cigarettes on the inside thereof while the group 6 of cigarettes moves along the wrapping path P2 pushed to the back by a corresponding pusher.
  • each wrapping sheet 10 is arranged to be intercepted by a corresponding group 6 of cigarettes around which the wrapping sheet 10 folds in a "U" shape; in other words, each group 6 of cigarettes moving along the wrapping path P2 intercepts a corresponding wrapping sheet 10 arranged in the feeding station S3, causing the wrapping sheet 10 to be folded in a "U" shape.
  • the packer machine 22 comprises a feeding device 29 which cyclically feeds the wrapping sheets 21 into the feeding station S3, namely, arranges each wrapping sheet 10 in the feeding station S3 so that the wrapping sheet 10 is intercepted (as illustrated in Figure 9 ) by a corresponding group 6 of cigarettes that moves along the wrapping path P2.
  • the feeding device 29 comprises an unwinding station where a tape of wrapping material is unwound from a reel and is moved towards a cutting member of a known type which is arranged above the feeding station S3 and cyclically performs a transversal cut of the tape of wrapping material to separate the individual wrapping sheets 10 from the tape of wrapping material.
  • the wrapping path P2 starts in the transfer station S2 (where the groups 6 of cigarettes enter the wrapping conveyor 27) and ends in the transfer station S4 (where the partially formed sealed wraps 3 leave the wrapping conveyor 27); along the wrapping path P2 only the "U"-shaped folding of the wrapping sheet 10 is performed around the group 6 of cigarettes (as illustrated in Figure 10 ) and the simultaneous folding of two smaller flaps against the smaller side wall of the group 6 of cigarettes.

  • the packer machine 22 comprises a wrapping drum 45 that is arranged downstream of the transfer drum 42 (therefore also downstream of the wrapping conveyor 38), supports a plurality of pockets 46 each designed to contain the sealed wrap 3 and the collar 20, and is mounted so as to rotate (with intermittent motion, namely, " in step") around a horizontal rotation axis 47 parallel to the wrapping path P2 (and therefore perpendicular to the wrapping path P4) in order to move each pocket 46 along a wrapping path P6 having a circular shape and perpendicular to the wrapping path P2 (and therefore parallel to the wrapping path P4).
  • Each pocket 46 of the wrapping drum 45 receives a collar 20 in a feeding station S8 arranged upstream of the transfer station S7 along the wrapping path P6, receives a sealed wrap 3 (which couples to the previously fed collar 20) in the transfer station S7, receives a blank 21 in a feeding station S8, which is arranged downstream of the transfer station S7 along the wrapping path P6, and releases together the sealed wrap 3, the collar 20 and the blank 21 in a transfer station S10 arranged downstream of the feeding station S8 along the wrapping path P6.
  • each collar 20 is placed on the outer surface of the wrapping drum 45, in the area of a pocket 46 and is held in this position by suction; in the transfer station S7 a sealed wrap 3, entering the corresponding pocket 46 couples to the collar 20 previously fed and causes the collar 20 to be folded in a "U" shape.
  • each blank 21 is placed on the outer surface of the wrapping drum 45 in the area of a pocket 46 and is held in this position by suction; in the transfer station S10, a sealed wrap 3 exiting from the corresponding pocket 46, together with the collar 20, couples to the previously fed blank 21.
  • a pusher 48 is arranged in the transfer station S7, which cyclically moves from the bottom to the top to pull out a sealed wrap 3 from a pocket 43 of the transfer drum 42 and then insert the sealed wrap 3 into a pocket 46 of the wrapping drum 45.
  • the wrapping conveyor 27 moves each sealed wrap 3 being formed along the wrapping path P4 with the opposite side walls arranged parallel to the wrapping path P4, that the wrapping path P3 develops from the transfer station S4 to the transfer station S5 with an angle of 270° around the rotation axis 32, and that the wrapping drum 42 causes the completed sealed wrap 3 to rotate by 90° between the transfer station S6 and the transfer station S7 (namely, the wrapping path P5 develops from the transfer station S6 to the transfer station S7 with a width of 90° around the rotation axis 44) .
  • the packer machine 22 comprises a feeding device 49 which cyclically feeds the collars 20 into the feeding station S7, namely, arranges each collar 20 in front of a pocket 46.
  • the feeding device 49 comprises an unwinding station where a tape of wrapping material is unwound from a reel (not illustrated) and is moved (passing behind the wrapping conveyor 38) towards a known type of cutting member which is arranged alongside the feeding station S8 and cyclically carries out a transversal cut of the tape of wrapping material to separate the individual collars 20 from the tape of wrapping material.
  • the feeding device 49 could feed the collars 20 from the hopper.
  • the packer machine 22 comprises a feeding device 50 which cyclically feeds the blanks 21 into the feeding station S9, namely, arranges each blank 21 in front of a pocket 46.
  • the feeding device 50 comprises a moving conveyor 51 that moves a plurality of stacks of blanks 21 towards a hopper (not illustrated); furthermore, the feeding device 50 comprises a feeding drum 52 which supports a plurality of suction holding heads (not illustrated) each designed to hold a corresponding blank 21, and is mounted so as to rotate (with intermittent motion, namely, " in step") around a horizontal rotation axis 53 parallel to the rotation axis 47 in order to move each suction holding head along a circular feeding path parallel to the wrapping path P6.
  • the rotation of the feeding drum 52 cyclically moves each suction holding head from a pick-up station S11 where the suction holding head picks up a blank 21 from the bottom of the hopper to the feeding station S9, where the suction holding head transfers the blank 21 to the wrapping drum 45.
  • the packer machine 22 comprises a wrapping drum 54 which is arranged downstream of the wrapping drum 45, supports a plurality of pockets 55 each designed to contain a sealed wrap 3, a collar 20 and a blank 21, and is mounted so as to rotate (with intermittent motion, namely " in step") around a horizontal rotation axis 56 parallel to the rotation axis 47 (and therefore parallel to the wrapping path P2) in order to move each pocket 55 along a wrapping path P7 having a circular shape and being parallel to the wrapping path P6 (and therefore perpendicular to the wrapping path P2).
  • Each pocket 55 of the wrapping drum 52 receives a sealed wrap 3, a collar 20 and a blank 21 in the transfer station S10, folds the blank 21 downstream of the transfer station S10, and releases an almost complete pack 1 of cigarettes into a transfer station S12 located downstream of the transfer station S10 along the wrapping path P7.
  • the folding of each blank 21 is completed (thus completing the formation of the corresponding pack 1 of cigarettes) by folding some flaps immediately downstream of the wrapping drum 54.
  • each pack 1 of cigarettes is transferred to a belt drying conveyor 57 (illustrated in Figure 17 ) which moves the packs 1 of cigarettes in succession along a drying path P8 straight and perpendicular to the rotation axis 56 towards an output of the packer machine 22.
  • the collars 20 are fed to the pockets 46 of the wrapping drum 45 in the feeding station S8 arranged upstream of the transfer station S7 along the wrapping path P6 (namely, the feeding station S8 remains coupled to the wrapping drum 45); according to an alternative embodiment, the feeding station S8 for the collars 20 is moved in the area of the transfer drum 42 and therefore a pocket 43 of the transfer drum 42 initially receives a collar 20 in the feeding station S8, subsequently receives a sealed wrap 3 from the wrapping conveyor 38 in transfer station S6, and lastly transfers the sealed wrap 3 and the collar 20 together to wrapping drum 45 in the transfer station S7 (or a pocket 43 of transfer drum 42 could initially receive the sealed wrap 3 from the wrapping conveyor 38 in the transfer station S6 and subsequently a collar 20 in the feeding station S8).
  • each sealed wrap 3 is indirectly transferred from the wrapping conveyor 38 to a pocket 46 of the wrapping drum 45.
  • the presence of the transfer drum 42 allows, among other things, to impart a different orientation to the sealed wraps 3 between the wrapping conveyor 38 and the wrapping drum 45; namely, the transfer drum 42 can only be used to impart a different orientation to the sealed wraps 3 leaving the feeding of the collars 20 to the pockets 46 of the wrapping drum 45 in the feeding station S8.
  • the packer machine 22 comprises a feeding device 58, which in a feeding station S13 (arranged upstream of the input station S1 relative to the moving direction of the forming conveyor 26), cyclically inserts the reinforcement elements 11 (that are arranged folded in a U-shape inside the pockets 25) into the empty pockets 25 of the forming conveyor 26.
  • a folding device 59 is coupled to the forming conveyor 26 that is arranged immediately upstream of the transfer station S2 relative to the moving direction of the forming conveyor 26 and is configured to complete the folding of the reinforcement element 11 against a corresponding group 6 of cigarettes carried by a pocket 25; in particular, the folding device 59 folds the lower wall 14 by 90° relative to the front wall 12 and against the group 6 of cigarettes and, at the same time, folds the rear wall 15 by 90° relative to the lower wall 14 and against the group 6 of cigarettes.
  • a pusher of the wrapping conveyor 27 pulls out a group 6 of cigarettes coupled to a reinforcement element 11 by pushing on the lower wall of the group 6 of cigarettes and therefore with the interposition of the lower wall 14 of the reinforcement element 11. Thanks to the presence of the lower wall 14 of the reinforcement element 11 it is therefore possible to reduce the load stress on the group 6 of cigarettes, since the lower wall of the group 6 of cigarettes does not come into direct contact with a pusher.
  • This orientation of the filters 7 is very advantageous for the manufacturing of the sealed wrap 3 (since it allows to arrange the pull-out opening in the area of the filters 7 as normally required by consumers of packs of cigarettes), but it can become a problem in the wrapping unit C during the folding of the blank 21 as it differs from the orientation in the case of a pack of cigarettes with a traditional (namely, unsealed) wrap; for this reason the presence of the wrapping drum 30 and the transfer drum 42 is important which allow to change the orientation of the sealed wraps 3 between the wrapping unit A and the wrapping unit C.
  • the presence of the wrapping drum 30 allows, among other things, not to give a different orientation to the sealed wraps 3 between the wrapping conveyor 27 and the wrapping conveyor 38: the sealed wraps 3 being formed are moved longitudinally along the wrapping conveyor 27 and this orientation allows an easy "U”-shaped folding of the wrapping sheet 10 around the group 6 of cigarettes, and the sealed wraps 3 being formed are moved longitudinally also along the wrapping conveyor 38 and this orientation also allows an easy folding of the two open side edges of the wrapping sheet 10 (which has a tubular shape around the group 6 of cigarettes) by means of the so-called " soap-bar fold " (previously described and illustrated in Figure 16 ) and the subsequent stabilization by heat-sealing.
  • the conformation of the wrapping drum 30 illustrated in the attached figures gives the sealed wraps 3 being formed an overturning, since along the wrapping conveyor 27 the sealed wraps 3 being formed are moved longitudinally with the filters 7 of the groups 6 of cigarettes forward, while along the wrapping conveyor 38 the sealed wraps 3 being formed are moved longitudinally with the filters 7 of the groups 6 of cigarettes backwards.
  • the presence of the transfer drum 42 allows, among other things, to impart a different orientation to the sealed wraps 3 between the wrapping conveyor 38 and the wrapping drum 45; in particular, according to the positioning of the transfer drum 42, the presence of the transfer drum 42 can cause the sealed wraps 3 to rotate by 90° (as illustrated in the attached figures) or by 270° (but potentially also by180°).
  • the different orientation of the sealed wraps 3 imparted by the wrapping drum 30 and by the transfer drum 42 is particularly useful as it allows the conformation of the entire wrapping unit C not to be substantially modified, passing from the production of a pack 1 of cigarettes with a sealed wrap 3 to the production of a pack of cigarettes 1 with a traditional (unsealed) wrap or vice versa; namely, by adapting the packer machine 22 to the production of different packs of cigarettes instead of substantially modifying the conformation of the entire wrapping unit C to pass from a sealed wrap 3 to a traditional (unsealed) wrap or vice versa, a rotation is simply imparted to the sealed wraps 3 at the inlet of the wrapping unit C.
  • the "U"-shaped folding of the wrapping sheet 10 around the group 6 of cigarettes is performed along the wrapping conveyor 27 (as illustrated in Figure 10 ) and with the simultaneous folding of two smaller flaps against the smaller side wall of the group 6 of cigarettes and along the wrapping conveyor 27, the closing of the two open side edges of the wrapping sheet 10 is also performed (which has a tubular shape around the group 6 of cigarettes) by means of the so-called “soap-bar fold" (previously described and illustrated in figure 16 ); in fact, the packer machine 22 illustrated in Figure 24 comprises two folding devices 60, which are arranged opposite one another along the wrapping path P2 and are designed to close the two open side edges of the wrapping sheet 10 by means of the so-called “soap-bar fold" (previously described and illustrated in Figure 16 ).
  • each folding device 60 is of the passive type (namely, it is completely devoid of moving parts) and comprises only fixed folding helixes.
  • the folding devices 40 are absent (as they are replaced by the folding devices 60) and only the sealing devices 41 are arranged along the wrapping conveyor 38.
  • the following are carried out along the wrapping conveyor 27: the "U"-shaped folding of the wrapping sheet 10 around the group 6 of cigarettes (as illustrated in Figure 10 ) and the simultaneous folding of two smaller flaps against the smaller side wall of the group 6 of cigarettes, the closing of the two open side edges of the wrapping sheet 10 (which has a tubular shape around the group 6 of cigarettes) by means of the so-called " soap-bar fold " (previously described and illustrated in Figure 16 ), and finally also the closing of the last open end of the wrapping sheet 10 (with the complete folding of the wrapping sheet 10, but without any stabilization of the folded shape of the wrapping sheet 10).
  • the packer machine 22 comprises a folding device 61 which is arranged along the wrapping path P2 and is designed to close the last open end of the wrapping sheet 10.
  • the folding device 61 is of the active type (namely, it comprises moving parts) and is of the type described in the patent application EP3725690A1 and carries out the folding described and illustrated in this patent application.
  • the sealing devices 62 are arranged, which perform the sealing of the overlapping portions of the wrapping sheet 10 in the area of the lower wall of the sealed wrap 3.
  • the wrapping conveyor 38 comprises the annular-shaped conveyor belt 39, which is wound around two end pulleys (one of which is motorized) and supports a plurality of pushers 63, each of which is connected to the conveyor belt 39 by means of a support column 64 (narrow, namely, narrower than the pusher 63) and is designed to engage a wall of a corresponding sealed wrap 3 being formed in order to push the sealed wrap 3 being formed along the wrapping path P4.
  • the wrapping conveyor 38 comprises a horizontal channel which is delimited at least at the bottom and laterally (preferably also at the top in its initial part), is arranged along the wrapping path P4, and contains on the inside thereof each sealed wrap 3 being formed, while the sealed wrap 3 being formed moves along the wrapping path P4 pushed to the back by a corresponding pusher 63.
  • Each pocket 31 of the wrapping drum 30 has a through slot 65 (arranged at the bottom) which, in the transfer station S5, is oriented parallel to the wrapping path P4 and through which the support column 64 of a corresponding pusher 63 is designed to pass when the pocket 31 is in the transfer station S5.
  • each pusher 63 of the wrapping conveyor 38 enters a pocket 31 of the wrapping drum 30 stopped in the transfer station S5 to pull out, from the same pocket 31, a corresponding sealed wrap 3 being formed and then move the sealed wrap 3 being formed along the wrapping path P4.
  • the packer machine 22 described above has numerous advantages.
  • the wrapping unit B of the packer machine 22 described above allows the sealed wraps 3 of the packs of cigarettes to be produced with a high production quality (namely, having extremely precise and squared folds of the wrapping sheet 10) even when operating at a high production speed (namely, with a high number of sealed wraps 3 produced in the unit of time).
  • the packer machine 22 described above allows to change the format of the packs 1 of cigarettes in a relatively simple and fast way.
  • the packer machine 22 described above is compact and has optimal accessibility to all its components; in fact, an operator who is in front of the packer machine 22 is able to reach, with his/her own hands, all the active parts of the packer machine 22 in a simple, fast and ergonomic way. In particular, an operator who is in front of the packer machine 22 can easily reach, with his own hands, the hopper 23, the forming conveyor 26, the wrapping conveyor 27, the wrapping conveyor 38, and the wrapping drums 45 and 52.
  • the embodiment illustrated in the attached figures refers to the manufacturing of a pack of cigarettes, but the present invention can also be applied without substantial modifications to the manufacturing of any other type of pack of smoking articles (for example, a pack of cigars, a pack of electronic cigarettes of the liquid vaporization type, a pack of new generation cigarettes without tobacco combustion).
