[0001] This invention relates to a machine and a method for making cigarette packets of the type commonly known as "shoulder boxes". The term "shoulder box" is used to designate a packet comprising a base and a lid which is hinged to the base by means of an adhesive label which is glued both to the base and to the lid. Both the base and the lid have the shape of a flat, open-top box. Inside the base there is a collar which protrudes from the side walls of the base towards the lid to act as a guide and reference for lid movement and, by interfering slightly with the free movement of the lid, to keep the lid in contact with the base when the lid is in the closed position. The base houses a group of cigarettes comprising two superposed layers of cigarettes.
[0002] At present, a "shoulder-box" packet of this kind is made from a first blank, which is gummed and folded to form the base, a second blank which is independent of the first blank and which is gummed and folded to form the lid, a third blank which is independent of the first and second blanks and which is folded to form the collar and then placed inside the base and glued to the side walls of the base, and, lastly, a label which is wrapped around and glued to the base and lid in order to hinge the base to the lid. The three blanks are made independently of each other and fed manually to the different wrapping units. That means making a "shoulder-box" packet is a somewhat slow and complex process because it involves not only separately handling and manually loading three distinct blanks but also having to use three independent wrapping units, each of which folds a corresponding blank.
[0003] Moreover, production of a "shoulder-box" packet is further slowed if accessory components have to be placed inside it: for example, a spacer to be disposed on the base, or an inner frame, coupon or other insert to be disposed on top of the group of cigarettes.
[0004] This invention therefore has for an aim to provide a machine and a method for making cigarette packets of the "shoulder box" type to overcome the disadvantages described above with reference to the prior art.
[0005] More specifically, the aim of this invention is to provide a machine and a method for making cigarette packets of the "shoulder box" type capable of automating and simplifying the production of such packets and thereby reducing process times, even if accessory components need to be placed inside the packets.
[0006] These aims are achieved by a machine and a method for making cigarette packets of the "shoulder-box" type having the features set out in one or more of the appended claims.
[0007] Advantageously, thanks to the machine and method of the invention, it is possible to reduce process times and floor space required to put the machine in operation and to make both empty packets and complete packets including the necessary accessory components. Further features and advantages of the invention are more apparent from the following exemplary and therefore non-limiting description of a preferred and hence non-exclusive embodiment of a machine and a method for making cigarette packets of the "shoulder-box" type.

[0024] Preferably, the making-up unit 2 comprises at least two rotary conveyors, preferably carousels 21, 22, each located on one of the levels 18, 19 and each provided with hollows 23 configured to receive the assemblies.
[0025] Preferably, to be able to transfer the assemblies from one level 18 to the other level 19 through the hollows 23, the pusher 20a is movable transversely to the initial portion 3a.
[0026] Preferably, filling means 24 are provided which are configured to dispose a group 25 of cigarettes inside each collar 104 at a filling station 27 along the making-up path 3. The filling station 27 is preferably located upstream of the second and third feed paths P2 and P3 along the initial portion 3a of the making-up path 3.
[0027] The numeral 28 denotes accessory feed means configured to feed at least one continuous accessory band 29a, 29b suitable for making an accessory component for each packet 100: for example, a spacer 105 to be disposed on the base 101 or a coupon 106 to be disposed on the side of the lid 102 and/or on top of the group 25 of cigarettes. In the embodiment illustrated in Figure 2, the feed means 28 are configured to feed two continuous bands 29a, 29b to make two accessory components. Preferably, the continuous band 29a is used to make spacers 105 and the band 29b is used to make coupons 106. Other possible embodiments have only the band 29a or only the band 29b. Further possible embodiments are also imaginable where there are other uses for the band 29a and/or the band 29b.
[0028] The accessory feed means 28 are configured to move each continuous accessory band along a respective accessory feed path Pa, Pb. The accessory feed path meets the making-up unit 2 along the making-up path 3.
[0029] Preferably, the accessory feed path meets the initial portion 3a of the making-up path 3 at an intermediate portion between the first feed path P1 and the second and third feed paths P2, P3.
[0030] In the case where there are two or more continuous accessory bands, each accessory feed path Pa, Pb meets the making-up path 3 preferably at a single station and, still more preferably, at the filling station 27, if provided, irrespective of whether it is activated or not. The accessory feed path may be configured to merge into the initial portion 3a of the making-up path 3 in such a way that, at least when the packet is finished, the accessory component is positioned above or below the group 25 of cigarettes. In the case of the spacer 105, the accessory feed path Pa is configured to merge into the initial portion 3a of the making-up path 3 in such a way that the accessory component is positioned on the side of the base 101 which, in the example illustrated, is preferably at the top when the packet is being made up. In the case of the coupon 106, the accessory feed path is configured to merge into the initial portion 3a of the making-up path 3 in such a way that the accessory component is positioned above the group 25 of cigarettes or on the side of the lid 102 which, in the example illustrated, is preferably at the bottom when the packet is being made up.
[0031] The references 30a, 30b schematically represent cutting means located along the respective accessory feed path and configured to cut the continuous accessory band 29a, 29b along a transverse direction and to make a sequence of blanks 31 a, 31 b of the accessory component. In this case, the accessory feed means 28 are configured to move the sequence of blanks 31 a, 31 b along a final portion Pa', Pb' of the accessory feed path.
[0032] Preferably, the cutting means 30a, 30b are configured to partially cut the continuous accessory band 29a, 29b along the transverse direction in such a way as to make a sequence of blanks 31 a, 31 b of the accessory component, where two consecutive blanks are connected by at least one bridge 32a, 32b.
[0033] Preferably, the accessory feed path Pa, Pb comprises an end stretch P' disposed transversely of the initial portion 3a of the making-up path 3. If both the accessory feed path Pa and the accessory feed path Pb are present, the end stretch P' may be in common between them, as illustrated in the accompanying drawings.
[0034] The numeral 33 denotes transfer means, preferably a pusher, configured to transfer an end blank towards the initial portion 3a of the making-up path 3, thus separating it from the sequence of blanks 31 a, 31 b. The transfer means are configured to tear the bridge 32a - 32b, if present. With reference to a possible example embodiment, the transfer means 33 are configured to act simultaneously on the end blank 31 a, 31 b and, for example in certain cases, on the cigarette packet 25 going through the filling station 27.
[0035] The numeral 34 denotes folding means for folding the blanks 31 a, 31 b, configured to operate while the blanks are being transferred and preferably comprising at least one loading hopper 35a, 35b for loading the respective blank 31 a, 31 b.

[0040] In addition to the above, the final portion 3b of the making-up path further comprises two carousels 37 and 38 configured to receive the blanks 39 of the labels 103 and to apply them on the base 101 and lid 102 of each packet 100 using gumming means of known type not illustrated.
[0041] Transfer means, preferably a pusher 20b, are configured to transfer from the carousel 22 to the rotating carousel 37 the assembly now made up of the collar 104, the base 101, the blank 17 and the additional components previously inserted. The pusher 20b passes through the respective hollows of the rotating carousel 37, similar to the hollows 23, thereby making the lid 102.
[0042] Once the labels have been applied, the packets 100 thus obtained are accumulated in rows 40 to give the glue joining the label 103 to the base 101 and lid 102 enough time to dry. Cutting means might also be provided to trim the label 103.
[0043] In use, the machine 1 is suitable for implementing a method for making cigarette packets 100 of the "shoulder box" type according to this invention.
[0044] The method comprises feeding the first continuous band 5, which is suitable for making each collar 104, moving it along the first feed path P1 and preferably folding it along its main direction of extension to form the flat tubular band 10.
[0045] The flat tubular band 10 is cut transversely to make the sequence of flat collars 12 which are moved along the final stretch P1' of the first feed path P1 towards the initial portion 3a of the making-up path 3. When they enter the making-up path 3, the flat collars 12 are opened out until adopting the shape of the side walls of the base 101, and are inserted into the hollows 23 to form the collar 104.
[0046] The carousel 21 transports the open collars 104 along the initial portion 3a of the making-up path 3 as far as the filling station 27 (if provided, because it is optional) where the filling means 24 place a group 25 of cigarettes inside each collar 104.
[0047] Alternatively, the filling station might not be provided or might not be enabled so as to make empty packets to be filled with groups of cigarettes at a later stage.
[0048] At the same time as this, at least one accessory band 29a, 29b is fed along the respective accessory feed path Pa, Pb and partly cut transversely to make the sequence of blanks 31 a, 31 b which reach the initial portion 3a of the making-up path 3 at the filling station 27, if present, or at an intermediate portion located, for example, between the first feed path P1 and the second and third feed paths P2, P3. According to the type of accessory component (for example, spacer 105 or coupon 106), the respective blanks 31 a, 31 b are merged into the flow in such a way that the accessory component is disposed on top of or under the group 25 of cigarettes, with reference to the full packet 100.
[0049] In the case of the spacer 105, the respective accessory feed path Pa merges into the initial portion 3a of the making-up path 3 in such a way that the accessory component is disposed on the side of the base 101, preferably at the top when the packet is being made up. In the case of the coupon 106, the respective accessory feed path Pb merges into the initial portion 3a of the making-up path 3 in such a way that the accessory component is disposed on the side of the lid 102, preferably at the top when the packet is being made up. Preferably, the blanks 31 a, 31 b merge into the making-up path 3 in a direction transverse to the initial portion 3a of the making-up path. During this transfer, the blanks 31 a, 31 b are folded to make the respective accessory component and detached from the respective sequence of blanks if the respective bridge 32a, 32b is present.
[0050] At the same time as this, the second continuous band 7 is fed along the second feed path P2 and cut transversely to make the sequence of blanks 15 which, along the final stretch P2' of the second feed path P2, reach the initial portion 3a of the making-up path 3.
[0051] In the same way, the third continuous band 9 is fed along the third feed path P3 and cut transversely to make the sequence of blanks 17 which, along the final stretch P3' of the third feed path P3, reach the initial portion 3a of the making-up path 3.
[0052] In the embodiment illustrated, the blanks 15, intended for example to form the bases 101, are fed along the making-up path 3 upstream of the blanks 17, intended for example to form the lids 102. For example, the blanks 15 are fed at the carousel 21 and the blanks 17 are fed at the carousel 22. It should be noted that the above procedure can be followed in reverse.
[0053] Generally speaking, all the feed paths meet the making-up unit 2 along the making-up path 3. Thus, it is possible to make up the base 101 and the lid 102 onto the collar 104 and to add the accessory components, if any, along the making-up path 3 inside the making-up unit 2.
[0054] To make up the base 101 and the lid 102, the method preferably comprises moving, along the initial portion 3a of the making-up path 3, the assembly made up of the collar 104 associated with the respective blank 15 of the base 101 (or associated with the respective blank 17 of the lid 102 - embodiment not illustrated). Each assembly is transferred from one to the other of at least two levels 18 and 19 and the blanks are folded during the passage from one level to the other. Preferably, the assemblies are transferred between the different levels by being made to pass through respective hollows 23 of rotating carousels 21 and 22.
[0055] With reference to the embodiment illustrated in the drawings, each blank 15 is positioned above the respective collar 104 at the carousel 21 and folded while it is transferred from the carousel 21 to the carousel 22 by the pushing action imparted to it by the pusher 20a, thus making the base 101.
[0056] Next, each blank 17 is positioned under the respective collar 104 at the carousel 22 and folded while it is transferred from the carousel 22 to a further rotating carousel 37. The assembly now made up of the collar 104, the lid 102 and the blank 17 is transferred from the carousel 22 to the rotating carousel 37 by the action imparted to it by the pusher 20b which pushes it into a respective hollow of the rotating carousel 37, similar to the hollows 23, thus making the lid 102. Lastly, the blanks 39 of the labels 103 are applied to the base 101 and lid 102 of each packet 100.
