Definitions

• This invention relates to a wrapping unit to produce, together, two sealed wraps containing two corresponding groups of smoking articles.
• Rigid cigarette packs with hinged lids are currently the most popular cigarette packs on the market as they are easy to produce, easy and practical to use, and protect the cigarettes contained therein well.
• a rigid cigarette pack with a hinged lid comprises a wrap consisting of a group of cigarettes wrapped in a wrapping sheet and a rigid outer casing housing the wrap.
• the outer casing consists of a cup-shaped container housing the wrap and has an open top end and a lid, which is also cup-shaped and hinged to the container to rotate, in relation to the container itself, between an open and a closed position of the open end.
• a sealed (waterproof) wrap consisting of a waterproof and heat-sealable wrapping sheet with an opening for the extraction of the cigarettes, which is closed using a reusable closing label.
• a cigarette pack commercially called a "twin" pack
• the patent application WO2023180862A1 describes a wrapping machine that makes a rigid cigarette pack with a hinged lid of the "twin" type and in which two sealed wraps are made simultaneously by operating on a dual line.
• the wrapping machine comprises, among other things, a wrapping drum supporting multiple pairs of pockets, each of which is designed to contain a group of cigarettes coupled to a wrapping sheet (thus, a pair of axially adjacent pockets supports a pair of adjacent groups of cigarettes coupled to their respective wrapping sheets).
• the wrapping drum is coupled with three different sealing heads that are configured to create a transverse seal on two wrapping sheets folded in a tube around two corresponding groups of cigarettes contained in two adjacent pockets in separate and successive stages.
• the wrapping machine described in the patent application WO2023180862A1 is generally capable of ensuring a high final quality of the cigarette packs even when operating at a high production speed (measured as cigarette packs produced in a unit of time); however, it has been observed that the frequency of cigarette packs containing defective sealed wraps (in particular having irregular tears at an inner edge of the wrapping sheet) is relatively high.
• EP4371894A1 describes a wrapping machine implementing a method for waste management with recirculation of semi-finished articles.
• the purpose of this invention is to provide a wrapping unit to produce, together, two sealed wraps containing two corresponding groups of smoking articles; this wrapping unit is easy to manufacture and enables operation at a high production speed (measured as cigarette packs produced in a unit of time).
• a wrapping unit is provided to produce, together, two sealed wraps containing two corresponding groups of smoking articles, as claimed in the appended claims.
• a projection of the first common support body along the transfer direction is preferably external to the two pockets stationary in the transfer station so that, during the movement along the transfer direction, the first common support body always remains at a distance from the two pockets stationary in the transfer station.
• the first common support body preferably has a main extension along a direction perpendicular to the transfer direction.
• the first common support body preferably comprises a main bar oriented perpendicularly to the transfer direction and two supports, which, at one end, are integral to the main bar and, at the opposite end, are integral to a respective first active element.
• the first actuator system preferably comprises: a rack integral with the rod; a pinion meshing with the rack; and an electric motor rotating the pinion.
• the first transferring device is preferably placed in the centre of the wrapping drum.
• the first transferring device is preferably arranged in the first transfer station; a second transferring device is provided, which is arranged in the second transfer station, is configured to move the groups of smoking articles relative to the pockets, and comprises two first active elements designed to rest on respective walls of the groups of smoking articles.
• the second transferring device comprises a single second common support body to which the two second active elements are fixed, leaving a space between the two second active elements; and a second actuator system translating the second common support body relative to the two pockets along a straight transfer direction.
• the two transferring devices are preferably arranged at the centre of the wrapping drum side by side and on opposite sides of the rotation axis.
• the reference number 1 globally denotes a rigid, "twin" pack of cigarettes.
• the cigarette pack 1 comprises a container 2 consisting of rigid cardboard or card and shaped like a cup and a pair of sealed wraps 3 (one of which is better illustrated in Figure 4 ) housed side by side inside the container 2.
• the container 2 has an open top end and is provided with a lid 4, which is shaped like a cup and hinged to the container 2 along a hinge (illustrated in Figure 2 ) to rotate, in relation to the container 2, between an open position (illustrated in Figure 3 ) and a closed position (illustrated in Figures 1 and 2 ) of the open top end.
• Each sealed wrap 3 (better illustrated in Figure 4 ) encloses a group 5 of parallelepiped-shaped cigarettes (illustrated in Figure 5 ) and has an opening 6 on the top and front for extracting the cigarettes, which is delimited by a tearable pre-weakened line, is closed by a reusable closing label 7 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 sealed wrap 3 is devoid of the extraction opening 6 and the associated closing label 7 and has a removable upper portion, which is separated from the rest of the sealed wrap 3 by a tearable pre-weakened 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 tearable opening strip to facilitate breaking the sealed wrap 3 along the pre-weakened line.
• the sealed wrap 3 is obtained by folding a wrapping sheet 8 (illustrated in Figure 6 ), which is rectangular in shape, comprises at least one layer of airtight and heat-sealable plastic material, and is folded directly around the group 5 of cigarettes so that it is in direct contact with the cigarettes.
• a wrapping sheet 8 illustrated in Figure 6
• the shape of the sealed wrap 3 itself is stabilised by heat-sealing the overlapping portions of the wrapping sheet 8.
• the sealed wrap 3 may comprise a reinforcing element 9 (better illustrated in Figure 5 ), which is made of cardboard or stiff card, is "U"-shaped and is arranged inside the sealed wrap 3 in contact with the group 5 of cigarettes (that is, it is placed between the group 5 of cigarettes and the wrapping sheet 8).
• a reinforcing element 9 (better illustrated in Figure 5 ), which is made of cardboard or stiff card, is "U"-shaped and is arranged inside the sealed wrap 3 in contact with the group 5 of cigarettes (that is, it is placed between the group 5 of cigarettes and the wrapping sheet 8).
• the formation of the sealed wrap 3 involves first forming the group 5 of cigarettes and then folding the reinforcing element 9 around the group 5 of cigarettes; subsequently, the wrapping sheet 8 is folded around the group 5 of cigarettes coupled with the reinforcing element 9.
• the method for folding the wrapping sheet 8 around the group 5 of cigarettes coupled to the reinforcing element 9 is known and is, for example, described in patent application WO2023180862A1 ; alternatively, the two open side edges of the wrapping sheet 5 could be closed by means of two longitudinal sealing fins instead of the so-called "soap fold".
• each wrapping sheet is folded in a "U" shape around the group 5 of cigarettes (coupled to the reinforcing element 9) so that the wrapping sheet 8 folded in a "U" shape has two ends 10 and 11 protruding from the group 5 of cigarettes; the two ends 10 and 11 are then folded against each other to give a tubular shape to the wrapping sheet 8, and then the overlapping portions of the ends 10 and 11 are heat-sealed to each other to stabilise the tubular shape of the wrapping sheet 8 and form a sealing fin 12 on which the transverse heat-sealing is done. Finally, the overlapping, heat-sealed ends 10 and 11 (that is, the sealing fin 12) are folded against a lower wall of the sealed wrap 3 or against a front wall of the sealed wrap 3.
• a wrapping machine that is designed for making the cigarette pack 1 described above generally operates with intermittent motion (that is, a motion involving a cyclic alternation of motion phases and pause phases) and comprises a forming unit in which the groups 5 of cigarettes are formed in succession, a wrapping unit 13 (schematically illustrated in Figure 7 ) in which a respective wrapping sheet 8 is wrapped around each group 5 of cigarettes to make a sealed wrap 3, and a wrapping unit in which a blank is wrapped around each pair of sealed wraps 3 coupled together (that is, arranged side by side) to make the container 2 provided with the lid 4.
• intermittent motion that is, a motion involving a cyclic alternation of motion phases and pause phases
• a wrapping unit 13 (schematically illustrated in Figure 7 ) in which a respective wrapping sheet 8 is wrapped around each group 5 of cigarettes to make a sealed wrap 3
• a wrapping unit in which a blank is wrapped around each pair of sealed wraps 3 coupled together that is, arranged side by side
• the wrapping unit 13 (which produces two sealed wraps 3 containing two corresponding groups 5 of cigarettes together) comprises wrapping conveyors that are designed to advance the two groups 5 of cigarettes side by side along a wrapping path (partly circular, partly straight).
• each wrapping conveyor supports multiple pairs of adjacent pockets, each of which is configured to receive and accommodate a corresponding group 5 of cigarettes; thus, at each advancement step, each wrapping conveyor advances two adjacent pockets (transversely, that is, perpendicularly to the wrapping path) and thus two adjacent groups 5 of cigarettes contained in their respective adjacent pockets.
• the wrapping conveyors of the wrapping unit 13 receive the pairs of groups 5 of cigarettes already coupled to their respective reinforcing elements 9 from a forming conveyor of the forming unit and are configured to advance the pairs of groups 5 of cigarettes side by side, together with the corresponding reinforcing elements 9 and together with the corresponding wrapping sheets 8, along the wrapping path to fold each wrapping sheet 8 around the corresponding group 5 of cigarettes.
• the wrapping unit 13 comprises a wrapping conveyor 14 that receives the pairs of adjacent groups 5 of cigarettes at a transfer station S1 and is designed to advance the pairs of adjacent groups 5 of cigarettes together with the corresponding wrapping sheets 8 along a wrapping path P to (begin to) fold each wrapping sheet 8 around the corresponding group 5 of cigarettes.
• the wrapping path P extends from the transfer station S1 in which the wrapping conveyor 14 receives two groups 5 of cigarettes at a time, passes through a feeding station S2 in which each pair of adjacent groups 5 of cigarettes is coupled to a corresponding pair of adjacent wrapping sheets 8, and terminates at a transfer station S3 wherein the pairs of sealed wraps 3 being formed (that is, each consisting of a wrapping sheet 8 only partially folded around a corresponding group 5 of cigarettes) leave the wrapper conveyor 14.
• each wrapping sheet 8 is folded initially into a "U" shape and then into a tube around a corresponding group 5 of cigarettes, and the tubular wrap (having two open side ends) thus formed is stabilised by means of a transverse seal.
• the wrapping conveyor 14 comprises a wrapping drum 15 (arranged vertically) that is mounted so that it rotates around a horizontal rotation axis 16 and supports multiple pairs of pockets 17, each of which is designed to contain a group of cigarettes 5 coupled to a wrapping sheet 8 (thus, a pair of pockets 17 axially adjacent supports a pair 5 of adjacent groups of cigarettes coupled to their respective wrapping sheets 8).
• the wrapping drum 15 rotating about the axis of rotation 16 advances each pair of adjacent pockets 17 along the circular wrapping path P between the transfer station S1 wherein the pair of adjacent pockets 17 receives a pair of adjacent groups 5 of cigarettes from the forming conveyor, through the feeding station S2 wherein the pair of adjacent pockets 17 receives a pair of adjacent wrapping sheets 8 that are arranged outside of the pair of adjacent pockets 17, and a transfer station S4 wherein the pair of adjacent pockets 17 transfers the pair of adjacent groups 5 of cigarettes coupled to the wrapping sheets 8.
• the wrapping conveyor 14 comprises a wrapping drum 18 (arranged vertically) that is arranged immediately downstream of the wrapping drum 15, is mounted so that it rotates around a horizontal rotation axis 19 (parallel to the rotation axis 16), and supports multiple pairs of pockets 20, each of which is designed to contain a group of cigarettes 5 coupled to a wrapping sheet 8 (thus, a pair of axially adjacent pockets 20 supports a pair 5 of adjacent groups of cigarettes coupled to their respective wrapping sheets 8).
• the wrapping drum 18 rotating about the axis of rotation 19 advances each pair of adjacent pockets 20 along the circular wrapping path P between the transfer station S4 wherein the pair of adjacent pockets 20 receives a pair of adjacent groups 5 of cigarettes coupled to the wrapping sheets 8 from the wrapping drum 15 and the transfer station S3 wherein the pair of adjacent pockets 20 transfers the pair of adjacent groups 5 of cigarettes coupled to the wrapping sheets 8 to the wrapping drum 15.
• two adjacent wrapping sheets 8 are placed on the edge of the wrapping drum 15 at a respective pair of adjacent pockets 17 and move with the respective pair of adjacent pockets 17 to the transfer station S4; at the transfer station S4, the two adjacent groups of cigarettes 5, exiting the pair of adjacent pockets 17 of the wrapping drum 15 and entering the respective pair of adjacent pockets 20 of the wrapping drum 18, drag with them the two adjacent wrapping sheets 8, which, entering the pockets 20, fold in a "U" shape around the adjacent groups 5 of cigarettes.
• the wrapping unit 13 comprises two folding devices 21, each of which is coupled to the wrapping drum 18 and is configured to fold a wrapping sheet 8 into a tube around the corresponding group 5 of cigarettes contained in a respective pocket 20.
• Each wrapping sheet 8 folds in a "U" shape around the corresponding group 5 of cigarettes when the group 5 of cigarettes enters (together with the wrapping sheet 8) the respective pocket 20 in the transfer station S4; in addition, each folding device 21 performs the tubular folding of each wrapping sheet 8 around the corresponding group 5 of cigarettes.
• the wrapping drum 18 advances a succession of pairs of adjacent groups 5 of cigarettes coupled to the wrapping sheets 8 (by means of corresponding pairs of adjacent pockets 20) along the wrapping path P and then the two folding devices 21 are placed side by side to perform the folding of two wrapping sheets 8 around two adjacent groups 5 of cigarettes at the same time.
• each sealing device 22 comprises three different sealing heads 23 (illustrated in Figure 9 ) arranged in succession around the wrapping drum 18 (that is, along the wrapping path P) in such a way that the transverse sealing on each wrapping sheet 8 folded into a tube is performed in three distinct and successive steps.
• the wrapping drum 18 advances a succession of pairs of adjacent groups 5 of cigarettes coupled to the wrapping sheets 8 along the wrapping path P and then the two sealing devices 22 are placed side by side to seal two wrapping sheets 8 around two adjacent groups 5 of cigarettes at the same time.
• a feeding station S2 where pairs of adjacent wrapping sheets 8 are placed on the edge of the wrapping drum 16 at a pair of adjacent pockets 18 (containing two respective adjacent groups 5 of cigarettes).
• two adjacent wrapping sheets 8 may either already be completely separated (that is, there is no residual joining point between the two adjacent wrapping sheets 8 that are therefore completely independent of each other) or the two adjacent wrapping sheets 8 may be joined by one or more tearable joining points that will be torn off later to permanently separate the two adjacent wrapping sheets 8 (as described in patent application EP3653518A1 ).
