Definitions

  • the present invention relates to a packaging machine and to a wrapping method for the production of a pack of tobacco articles.
  • the present invention finds advantageous application to a pack of cigarettes, to which the following description will make explicit reference without the loss of generality.
  • a pack of cigarettes normally comprises an inner wrapping, which is formed by a group of cigarettes wrapped in a wrap of metalized paper or heat sealable plastic material, and an outer container which houses the inner wrapping and can be of a soft type (namely formed by a flexible wrap which wraps the inner wrapping) or of a rigid type (namely formed by a cardboard rigid blank and generally provided with a hinged lid).
  • a collar is coupled to the inner wrapping which subsequently will be glued on the inside of a rigid container with hinged lid, which forms the outer container.
  • the object of the present invention is to provide a packaging machine and a wrapping method for the production of a pack of tobacco articles, which packaging machine and wrapping method are free from the drawbacks described above and are, at the same time, easy and inexpensive to manufacture.
  • FIGs 1 and 2 number 1 denotes as a whole, a rigid pack of cigarettes.
  • the pack 1 of cigarettes comprises a cup-shaped outer container 2 made of cardboard or rigid paperboard and an inner wrapping 3 (illustrated in Figures 4 and 5 or in Figure 8 ) which is housed inside the container 2 and encloses a parallelepiped shaped group 4 of cigarettes with filter (illustrated in Figure 3 ).
  • the inner wrapping 3 is sealed and has, at the top and in front, a pull-out opening 5 for the cigarettes closed by a reusable closing label 6; the inner wrapping 3 is formed by using a heat-sealable wrap 7 (illustrated in Figure 7 ), which has a rectangular shape, is folded around the group 4 of cigarettes, and once folded is stabilized by means of heat sealing (namely overlapping portions of the wrap 7 are connected one to the other in a secure manner by means of heat sealing).
  • a rigid reinforcement element (illustrated in Figure 6 ) is provided, which is, then, located inside the inner wrapping 3 (namely it is completely surrounded by the inner wrapping 3).
  • the inner wrapping 3 is not sealed and is formed by folding a wrap 9 (illustrated in Figure 9 ) of metalized paper around the group 4 of cigarettes; once folded, the wrap 9 normally is not stabilized, namely, it is completely free from glue or sealing.
  • the outer container 2 of the pack 1 of cigarettes is obtained by folding a blank 10 (illustrated in Figure 10 ) around the inner wrapping 3 (of sealed type as illustrated in Figures 4-7 or unsealed type as illustrated in Figures 8 and 9 ).
  • the pack 1 of cigarettes can comprise a collar 11 (illustrated flat in Figure 11 ) which is fixed (normally by means of gluing U-folded inside of the outer container 2 so as to partially project outside of an upper open end and engage a corresponding inner surface of a lid when the lid 4 itself is arranged in a closing position.
  • the collar 11 is absent when the inner wrapping 3 is sealed (and hence it is provided with the reinforcing element 8, which partly also performs the function of the collar 11, on the inside thereof) and the collar 11 is present when inner wrapping 3 is unsealed.
  • reference number 12 denotes as a whole an intermittent packaging machine (namely actuated with an intermittent motion which provide a cyclic alternation of motion steps and standstill steps), which is designed to produce the pack 1 of cigarettes.
  • the packaging machine 1 comprises a forming unit 13 of known type wherein the group 4 of cigarettes is formed, a wrapping unit 14 wherein the inner wrapping 3 is created by folding the wrap 7 (so as to form the inner wrapping 3 of sealed type) around the group 4 of cigarettes or by folding the wrap 9 (so as to form the inner wrapping 3 of unsealed type) around the group 4 of cigarettes, and a wrapping unit 15 of known type wherein the outer container 2 is created by folding the blank 10 around the inner wrapping 3.
  • the packaging machine 1 comprises a feeding unit 16, which connects one to the other the wrapping units 14 and 15, namely receives the inner wrapping 3 from the wrapping unit 14 in an input station S1 and feeds the inner wrapping 3 to the wrapping unit 15 in an output station S2.
  • the feeding unit 16 comprises a horizontally arranged feeding wheel 17 which is mounted so as to rotate (with intermittent motion) around a vertical rotation axis 18 and supports a plurality of peripheral pockets 19, each of which is designed to contain an inner wrapping 3.
  • the rotation of the feeding wheel 17 around the rotation axis 18 moves each pocket 19 along a circular feeding path P1, which starts from the input station S1, wherein the pocket 19 receives an inner wrapping 3 (containing a group 4 of cigarettes) from the wrapping unit 14, and ends in a transfer station S3, wherein the inner wrapping 3 is released.
  • the feeding unit 16 comprises a horizontally arranged feeding wheel 20 which is mounted so as to rotate (with intermittent motion) around a vertical rotation axis 21 (parallel to the rotation axis 18) and supports a plurality of peripheral pockets 22, each of which is designed to contain an inner wrapping 3.
  • the rotation of the feeding wheel 20 around the rotation axis 21 moves each pocket 22 along a circular feeding path P2 that starts from the transfer station S3, wherein the pocket 22 receives an inner wrapping 3 (containing a group 4 of cigarettes) from a pocket 19 of the feeding wheel 17, and ends in the output station S2 where the inner wrapping 3 is released to the wrapping unit 15.
  • the feeding unit 16 further comprises a feeding station S4 wherein a collar 11 is fed to each pocket 19 of the feeding wheel 17 upstream of the input station S1 (namely when the pocket 19 is still " empty ", i.e. without the inner wrapping 3) so that, in the input station S1, the inner wrapping 3 (containing a group 4 of cigarettes) by entering into the pocket 19 of the feeding wheel 17 would couple to the collar 11, previously fed.
  • each inner wrapping 3 (containing a group 4 of cigarettes) is transferred from a pocket 19 of the feeding wheel 17 to a pocket 22 of the feeding wheel 20 together with the corresponding collar 11.
  • each collar 11 is "U"-folded in the feeding station S4 as it enters the pocket 19 of the feeding wheel 17; alternatively, each collar 11 remains flat in the feeding station S4 and is “U"-folded around the inner wrapping 3 (containing a group 4 of cigarettes) in the input station S1 when the inner wrapping 3 enters the pocket 19 of the feeding wheel 17, or each collar 11 remains flat in the feeding station S4 and in the input station S1 and is "U"-folded around the inner wrapping 3 (containing a group 4 of cigarettes) in the transfer station S3 when the inner wrapping 3 enters the pocket 22 of the feeding wheel 20.
  • a transfer device 23 is arranged which transfers each inner wrapping 3 (containing a group 4 of cigarettes) from the respective pocket 19 of the feeding wheel 17 to the respective pocket 22 of the feeding wheel 20.
  • the transfer device 23 is of a known type and can comprise, as an example, a pusher and a counter-pusher, which are arranged on opposite sides of the inner wrapping 3, hold (clamp) the inner wrapping 3 together by engaging two opposite faces of the inner wrapping 3 and move vertically the inner wrapping 3 of the respective pocket 19 of the feeding wheel 17 to the respective pocket 22 of the feeding wheel 20.
  • the transfer station S3 (and hence the corresponding transfer device 23) can only be arranged in an exchange position A or B wherein a pocket 19 of the feeding wheel 17 is aligned (in particular, vertically aligned in the embodiment illustrated in the attached figures) with a corresponding pocket 22 of the feeding wheel 20.
  • each pocket 19 of the feeding wheel 17 is aligned (in particular, vertically aligned in the embodiment illustrated in the attached figures) with a corresponding pocket 22 of the feeding wheel 20 in two different exchange positions A and B separated and (relatively) apart one from the other; consequently, in the feeding unit 16 illustrated in Figures 13 and 15 , the transfer station S3 can be indifferently located in the exchange position A (as illustrated in the alternative of Figure 14 ), or in the exchange position B (as illustrated in the alternative of Figure 13 ).
  • the location of the transfer station S3 (and hence of the corresponding transfer device 23) along the first feeding path P1 and along the second feeding path P2 can be varied by changing the length of the first feeding path P1 and of the second feeding path P2, and in order to change the orientation imparted to inner wrapping 3 (containing a group 4 of cigarettes) as it moves through the feeding unit 16.
  • the group 4 of cigarettes contained in the inner wrapping 3 has, in the input station S1, the filters oriented towards the inside of the wrapping wheel 17 and has, in the output station S2, the filters oriented in front relative to the feed direction along the feeding path P2;
  • the transfer station S3 is located in the exchange position B (as illustrated in the alternative of Figure 13 )
  • the group 4 of cigarettes contained in the inner wrapping 3 has, in the input station S1, the filters oriented towards the outside of the wrapping wheel 17 and has, in the output station S2, the filters oriented in front relative to the feed direction along the feeding path P2.
  • the displacement of the transfer station S3 between the exchange positions A and B occurs when the packaging machine 12 is stopped, usually following a change of format operation during which the packaging machine 12 is changed so as to produce a different type of pack 1 of cigarettes (as will be better explained hereinafter).
  • the same transfer device 23 can be moved between the exchange position A and the exchange position B to subsequently move the transfer station S3 between positions A and B; in other words, the feeding unit 16 comprises a single transfer device 23 which is alternately placed in the exchange position A or in the exchange position B.
  • the feeding unit 16 comprises two transfer devices 23 which can be used alternatively and are arranged respectively in the exchange position A and in the exchange position B; in this embodiment, the change in the placement of the transfer station S3 may also occur with the packaging machine 12 in motion (namely, operating), since it does not require any physical modification to the feeding unit 16 (it is sufficient to disable the transfer device 23 previously active and activate the other transfer device 23).
  • the feeding wheel 17 partially overlaps the other feeding wheel 20 so that in each exchange position A and B the pocket 19 of the feeding wheel 17 overlaps and is aligned with the pocket 22 of the feeding wheel 20.
  • the feeding wheel 17 is partially arranged above the feeding wheel 20 (therefore, the transfer of the inner wrappings 3 in the exchange positions A and B takes place from top to bottom), but according to a different and perfectly equivalent embodiment, the feeding wheel 17 can be partially arranged under the feeding wheel 20 (therefore, the transfer of the inner wrappings 3 in the exchange positions A and B takes place from bottom to top).
  • each pocket 19 is oriented in a radial manner relative to the corresponding rotation axis 18 and in the other feeding wheel 20 each pocket 22 is oriented in a tangential manner relative to the corresponding rotation axis 21; according to a different and perfectly equivalent embodiment, the pocket 19 is oriented in a tangential manner relative to the corresponding rotation axis 18 and in the other feeding wheel 20 each pocket 22 is oriented in a radial manner relative to the corresponding rotation axis 21.
  • each pocket 19 and 22 has a rectangular section having a longer side and a shorter side (thus reproducing the shape of the inner wrappings 3): in the feeding wheel 17 each pocket 19 is oriented in a radial manner relative to the corresponding rotation axis 18 and therefore, the longer side of each pocket 19 is oriented in a radial manner relative to the corresponding rotation axis 18, whereas in the feeding wheel 20 each pocket 22 is oriented in a tangential manner relative to the corresponding rotation axis 21 and therefore the longer side of each pocket 22 is oriented in a tangential manner relative to the corresponding rotation axis 21.
  • a pocket 19 of the feeding wheel 17 overlaps and is aligned with a pocket 22 of the feeding wheel 20 in two separate and distinct exchange positions A and B; therefore, the transfer station S3 can be indifferently located in both the exchange positions A and B without making any change to the feeding wheels 17 and 20.
  • a pocket 19 of the feeding wheel 17 overlaps and is aligned with a pocket 22 of the feeding wheel 20 in a single exchange position and then, to change the location of the transfer station S3 along the feeding path P1, it is necessary to move the feeding wheel 17 relative to the feeding wheel 20.
  • the feeding wheel 17 is mounted movable to change its position relative to the other feeding wheel 20 (which, instead, is always in the same position) in order to change the position of the transfer station S3 along its own feeding path P1 (while the feeding path P2 remains unchanged);
  • the feeding wheel 20 is mounted movable so as to change its relative position with respect to the other feeding wheel 17 (which is always in the same position) in order to change the position of the transfer station S3 along its own feeding path P2 (while the feeding path P1 remains unchanged).
  • the position of the input station S1 and the position of the transfer station S3 relative to the frame 24 of the packaging machine 12 remains unchanged (that is, the input station S1 and the transfer station S3 are arranged in fixed position in the frame 24 of the packaging machine 12); in other words, the movement of the feeding wheel 17 relative to the frame 24 of the packaging machine 12 causes a relative displacement of the feeding wheel 17 with respect to the feeding wheel 20, with respect to the input station S1, and with respect to the transfer station S3.
  • the movement of the movable feeding wheel 17 does not change the position of the input station S1, the position of the output station S2, and the position of the transfer station S3 with respect to the frame 24 of the packaging machine 12.
  • the movable feeding wheel 17 is designed to translate perpendicular to its own rotation axis 18 along a straight and horizontal displacement direction D.
  • a slide is provided, which is mounted so as to slide along a fixed guide and supports at least one bearing wherein a shaft of the movable feeding wheel 17 is mounted in a rotary manner.
  • the two feeding wheels 17 and 20 have the same number of pockets 19 and 22 and in particular eight pockets 19 and 22; according to other, and perfectly equivalent, embodiments not illustrated, the two feeding wheels 17 and 20 have the same number of pockets 19 and 22 and said number is different from eight (e.g. ten or twelve pockets 19 and 22) or the two feeding wheels 17 and 20 have a different number of pockets 19 and 22 (e.g. nine and twelve pockets 19 and 22, twelve and six pockets 19 and 22, eight and sixteen pockets 19 and 22).
  • the forming unit 13 comprises a hopper 25 provided with a plurality of mouths from which the groups 4 of cigarettes are cyclically extracted; in front of the hopper 25 a belt forming conveyor 26 is provided, which supports a plurality of forming pockets 27, each of which receives a corresponding group 4 of cigarettes from a mouth of the hopper 25.
  • the wrapping unit 14 comprises a transfer wheel 28 which rotates by steps around a horizontal rotation axis and is provided with a plurality of transfer pockets 29, each of which receives a corresponding group 4 of cigarettes from a forming pocket 27 of the forming conveyor 26.
  • a transfer wheel 28 which rotates by steps around a horizontal rotation axis and is provided with a plurality of transfer pockets 29, each of which receives a corresponding group 4 of cigarettes from a forming pocket 27 of the forming conveyor 26.
  • the reinforcing elements 8 are coupled to the corresponding groups 4 of cigarettes.
  • the wrapping unit 14 comprises a wrapping wheel 30, which rotates by steps around a vertical rotation axis and is provided with a plurality of wrapping pockets 31, each of which receives a corresponding group 4 of cigarettes from a transfer pocket 29 of the transfer wheel 28 together with a wrap 7 which is "U"-folded around the group 4 of cigarettes as it enters the wrapping pocket 31.
  • the wrapping wheel 30 feeds the groups 4 of cigarettes along an initial and semi-circular segment of a wrapping path P3 wherein each wrap 7 is folded and stabilized around a corresponding group 4 of cigarettes so as to form a sealed inner wrapping 3.
  • a feed conveyor 32 is interposed, which vertically feeds the flat wraps 7 so as to interpose each wrap 7 between a transfer pocket 29 of the transfer wheel 28 and a corresponding wrapping pocket 31 of the wrapping wheel 30. While a group 4 of cigarettes is contained in a wrapping pocket 31 of the wrapping wheel 30, the corresponding wrap 7 is folded so as to assume a tubular shape (having two opposite open ends) and subsequently the tubular shape of the wrap 7 is stabilized by performing a cross heat-sealing.
  • the wrapping unit 14 comprises a straight wrapping conveyor 33 which receives the groups 4 of cigarettes partially wrapped in the corresponding wraps 7 from the wrapping pockets 31 of the wrapping wheel 30 and feeds the groups 4 of cigarettes along a final and straight segment of the wrapping path P3 along which the folding of each wrap 7 is completed so as to complete the creating of the corresponding inner wrapping 3; in particular, along the final and straight segment of the wrapping path P3, the two open ends of each tubular wrap are closed and therefore the corresponding inner wrapping 3 is stabilized by performing a pair of longitudinal heat-sealing opposite one to the other.
  • the wrapping unit 14 comprises a transfer wheel 34 which rotates by steps around a horizontal rotation axis and is provided with a plurality of transfer pockets 35, each of which receives a corresponding inner wrapping 3 from the straight wrapping conveyor 33 in a transfer station S5, and feeds the inner wrapping 3 to a corresponding pocket 19 of the feeding wheel 17 of the feeding unit 16 in the input station S1.
  • the wrapping unit 15 comprises a wrapping wheel 36, which rotates by steps around a horizontal rotation axis and is provided with a plurality of wrapping pockets 37, each of which receives a corresponding inner wrapping 3 from a pocket 22 of the feeding wheel 20 in the output station S2 together with a blank 10 which is "U"-folded around the inner wrapping 3 as it enters the wrapping pocket 37.
  • a feeding conveyor 38 is arranged, which horizontally feeds the blanks 10 so as to interpose each blank 10 between a pocket 22 of the feeding wheel 20 and a corresponding wrapping pocket 37 of the wrapping wheel 36.
  • the packaging machine 12 is illustrated, in a first operating configuration designed to produce the pack 1 of cigarettes illustrated in Figures 1 and 2 and containing the sealed inner wrapping 3 illustrated in Figures 4 and 5 .
  • the feeding unit 16 is arranged as illustrated in Figure 14 or as illustrated in Figure 15 so as to receive, in the input station S1, the inner wrappings 3 (containing the respective groups 4 of cigarettes) with the filters arranged in front.
  • the packaging machine 12 is illustrated, in a second operating configuration designed to produce the pack 1 of cigarettes illustrated in Figures 1 and 2 and containing the unsealed inner wrapping 3 illustrated in Figure 8 .
  • the feeding unit 16 is arranged as illustrated in Figure 13 or as in Figure 16 so as to receive, in the input station S1, the inner wrappings 3 (containing the respective groups 4 of cigarettes) with the filters arranged in the back.
  • the forming unit 13 is unchanged with respect to the first operating configuration illustrated in Figure 17 ; in other words, when changing from the first operating configuration illustrated in Figure 12 to the second operating configuration illustrated in Figure 17 (and vice versa), the forming unit 13 is not subjected to any change.
  • the wrapping unit 14 is changed as the vertical rotation axis wrapping wheel 30 is no longer used and is replaced by a wrapping wheel 39 rotating by steps around a horizontal rotation axis and is provided with a plurality of wrapping pockets 40, each of which receives a corresponding group 4 of cigarettes from a transfer pocket 29 of the transfer wheel 28 together with a wrap 9 which is "U"-folded around the group 4 of cigarettes as it enters the wrapping pocket 40.
  • the wrapping wheel 39 feeds the groups 4 of cigarettes along an initial and semi-circular segment of a wrapping path P4 wherein, each wrap 7 is folded around a corresponding group 4 of cigarettes so as to form an unsealed inner wrapping 3.
  • the feed conveyor 32 is always interposed, which vertically feeds the wraps 9 so as to interpose each wrap 9 between a transfer pocket 29 of the transfer wheel 28 and a corresponding wrapping pocket 40 of the wrapping wheel 39. While a group 4 of cigarettes is contained in a wrapping pocket 40 of the wrapping wheel 39, the corresponding wrap 9 is folded to assume a tubular shape (having two opposite open ends).
  • the wrapping unit 14 is changed as the straight wrapping conveyor 33 (which, for clarity, is not illustrated in Figure 17 ) is no longer used and is replaced by another straight wrapping conveyor 41, which receives the groups 4 of cigarettes partially wrapped in the corresponding wraps 9 from the wrapping pockets 40 of the wrapping wheel 39 and feeds the groups 4 of cigarettes along a final and straight segment of the wrapping path P4 along which the folding of each wrap 9 is completed so as to complete the creating of the corresponding inner wrapping 3; in particular, along the straight segment of the wrapping path P4, the two open ends of each tubular wrap are closed.
  • the inner wrappings 3 are transferred to corresponding transfer pockets 35 of the transfer wheel 34 in a transfer station S6 (different and separated from the transfer station S5, at the end of the straight wrapping conveyor 33).
  • the two straight wrapping conveyors 33 and 41 are arranged in different positions, namely they are parallel to and spaced apart one with the other, and therefore are side by side one from the other; consequently, the two straight wrapping conveyors 33 and 41 can " coexist ", namely, remain both in the corresponding operating positions without interfering one with respect to the other.
  • the two straight wrapping conveyors 33 and 41 are mounted in a fixed position on the frame 24 of the packaging machine 12 and remain both mounted in the corresponding operating positions in the first operating configuration and in the second operating configuration (obviously in the first operating configuration only the straight wrapping conveyor 33 receives the groups 4 of cigarettes from the wrapping wheel 30, whereas in the second operating configuration only the straight wrapping conveyor 41 receives the groups 4 of cigarettes from the wrapping wheel 39).
  • the two wrapping wheels 30 and 39 are substantially in the same position and hence it is evident that the two wrapping wheels 30 and 39 cannot " coexist ", namely, remain both in the corresponding operating positions without interfering one with respect to the other; consequently, the wrapping wheels 30 and 39 are mounted in a movable manner so as to translate relative to the frame 24 of the packaging machine 12 between an operating position, taken when using its own straight wrapping conveyor 33 or 41, and a rest position, taken when the other straight wrapping conveyor 41 or 33 is used. Each wrapping wheel 30 and 39 translates along a linear movement direction between the operating position and the rest position.
  • the wrapping wheel 30 is mounted on a support 42, which is mounted movable on the frame 24 of the packaging machine 12 so as to translate vertically relative to the frame 24 itself (therefore parallel to the rotation axis of the wrapping wheel 30); similarly, the wrapping wheel 39 is mounted on a support 43 which is mounted movable on the frame 24 of the packaging machine 12 to translate horizontally relative to the frame 24 (therefore perpendicular to the rotation axis of the wrapping wheel 39).
  • the frame 24 of the packaging machine 12 has a parking compartment 44, inside of which the wrapping wheel 39 is arranged in the rest position (as illustrated in Figures 12 and 18 ).
  • the wrapping wheel 30 and the straight wrapping conveyor 33 together, form a first wrapping conveyor, which receives a group 4 of tobacco articles from the forming unit 13 and feeds the group 4 of tobacco articles along the wrapping path P3 so as to create a first type of folding of the wrap 7 in order to form a sealed inner wrapping 3.
  • the wrapping wheel 39 and the straight wrapping conveyor 41 together, form a second wrapping conveyor, which receives a group 4 of tobacco articles from the forming unit 13 and feeds the group 4 of tobacco articles along the wrapping path P4 so as to create a second type of folding of the wrap 9 in order to form an unsealed inner wrapping 3.
  • the second wrapping conveyor (formed by the wrapping wheel 39 and by the straight wrapping conveyor 41) is arranged close to the first wrapping conveyor (formed by the wrapping wheel 30 and by the straight wrapping conveyor 33) and can be used as an alternative to the first wrapping conveyor.
  • the vertical rotation axis wrapping wheel 30 imparts a change in orientation to the groups 4 of cigarettes, namely, upstream of the wrapping wheel 30 (thus exiting from the hopper 25) the groups 4 of cigarettes have the filters in the back whereas downstream of the packing wheel 30 the groups 4 of cigarettes have the filters in front (as illustrated in Figures 14 and 15 ); instead, the horizontal rotation axis wrapping wheel 39 does not imparts any change in orientation to the groups 4 of cigarettes, namely upstream of the wrapping wheel 39 (thus exiting from the hopper 25), and downstream of the wrapping wheel 39, the groups 4 of cigarettes have always the filters in the back (as illustrated in Figures 13 and 16 ).
  • the groups 4 of cigarettes change their orientation by changing the operating configuration of the packaging machine 12; with the methods described above, when changing the operating configuration of the packaging machine 12 the feeding unit 16 is also changed, by changing the position of the transfer station S3 so that in the output station S2 the groups 4 of cigarettes (contained in the inner wrappers 3) have always the same orientation.
  • the type of inner wrapping 3 produced is changed (sealed inner wrapping 3 in the first operating configuration and unsealed inner wrapping 3 in the second operating configuration) while the outer container 2 remains substantially unchanged (obviously the graphics and/or dimensions of the outer container 2 can change, but its shape remains the same).
  • the packaging machine 12 is further designed to assume a third operating configuration wherein the type of outer container 2 is changed: instead of creating the conventional outer container 2 illustrated in Figures 1 and 2 , the outer container 2 referred to as " zippo ", illustrated in Figures 20 and 21 , is created.
  • a longitudinally developed blank 10 (illustrated, for example, in Figure 10 ) and a traditional small-size collar 11 (illustrated, for example, in Figure 11 ) are used; whereas, to create the " zippo " outer container 2 illustrated in Figures 20 and 21 a transversally developed blank 45 (illustrated, for example, in Figure 23 ) and an unfolded large-size collar 46 (illustrated, for example, in Figure 23 ) are used.
  • the feeding unit 16 illustrated in Figures 13 and 14 is changed as illustrated in Figure 24 by replacing the feeding wheel 20, having the pockets 22 oriented in a tangential manner relative to the corresponding rotation axis 21, with an similar feeding wheel 20 having the pockets 22 oriented in a radial manner relative to the corresponding axis 21; said change of orientation of the pockets 22 of the feeding wheel 20 is necessary in order not to rotate the entire wrapping wheel 36 of the wrapping unit 15 which can remain in the same identical position (obviously it is necessary to replace the wrapping pockets 37 of the wrapping wheel 36 and the folding devices associated with the wrapping wheel 36, but the position of wrapping wheel 36 remains unchanged).
  • the blank 10 has a longitudinal development whereas the blank 45 has a transversal development (namely, the blanks 10 and 45 have developments perpendicular one to the other), therefore in order to fold the blanks 10 and 45 in the same type of wrapping wheel 36 (i.e.
  • the central drum of the feeding wheel 17 is replaced with another central drum with different diameter (particularly of smaller diameter) and always having the pockets 19 oriented in a radial manner; this replacement of the central drum of the feeding wheel 17 entails a translation of the rotation axis 18 of the feeding wheel 17 (hence, as described above a slide is provided, which supports at least one bearing wherein a shaft of the feeding wheel 17 is mounted in a rotary manner).
  • the feeding unit 16 comprises feeding station S4, wherein a collar 46 is fed to each pocket 19 of the feeding wheel 17 upstream of the input station S1 (namely, when pocket 19 is still " empty ", i.e. without the inner wrapping 3) so that in the input station S1 the inner wrapping 3 (containing a group 4 of cigarettes) by entering into the pocket 19 of the feeding wheel 17 couples with the previously fed collar 46.
  • the feeding unit 16 in the first operating configuration (illustrated in Figure 13 ) and in the second operating configuration (illustrated in Figure 14 ) comprises the feeding wheel 17, wherein each pocket 19 is oriented in a radial manner relative to the corresponding rotation axis 18 and the feeding wheel 20, wherein each pocket 22, is oriented in a tangential manner relative to the corresponding rotation axis 21 so as to change the orientation of the inner wrappings 3 (containing respective groups of 4 cigarettes) as it moves through the feeding unit 16; namely, the inner wrappings 3 (containing respective groups 4 of cigarettes) enter with a radial orientation in the input station S1 and exit with a tangential orientation in the output station S2.
  • the first operating configuration (illustrated in Figure 13 ) and the second operating configuration (illustrated in Figure 14 ) are used with the longitudinally developed blank 10.
  • the feeding unit 16 in the third operating configuration comprises the feeding wheel 17, wherein each pocket 19 is oriented in a radial manner relative to the corresponding rotation axis 18, and the feeding wheel 20, wherein each pocket 22 is oriented in a radial manner relative to the corresponding rotation axis 21 so as not to change the orientation of the inner wrappings 3 (containing respective groups 4 cigarettes) as they move through the feeding unit 16; the inner wrappings 3 (containing respective groups 4 of cigarettes) enter with a radial orientation in the input station S1 and exit with a radial orientation in the output station S2.
  • the third operating configuration is used with the transversally developed blank 45.
  • the feeding unit 16 in the third operating configuration comprises the feeding wheel 17, wherein each pocket 19 is oriented in a tangential manner relative to the corresponding rotation axis 18 and the feeding wheel 20, in each pocket 22, is oriented in a tangential manner relative to the corresponding rotation axis 21 so as not to change the orientation of the inner wrappings 3 (containing respective groups 4 of cigarettes) as it moves through the feeding unit 16; the inner wrappings 3 (containing respective groups 4 of cigarettes) enter with a tangential orientation in the input station S1 and exit with a tangential orientation in the output station S2.
  • the longitudinal and transverse edges of the outer container 2 are straight; alternatively, the longitudinal and/or transverse edges of the outer container 2 may be rounded or bevelled.
  • the pack 1 of cigarettes contains a group 4 of cigarettes; alternatively, the pack 1 of cigarettes can contain any other kind of tobacco article such as cigar, electrical or electronic cigarettes (namely, cigarettes which generate an aerosol without combustion), cartridges and refills for electronic cigarettes, next-generation cigarettes.
  • the pack 1 of cigarettes can contain any other kind of tobacco article such as cigar, electrical or electronic cigarettes (namely, cigarettes which generate an aerosol without combustion), cartridges and refills for electronic cigarettes, next-generation cigarettes.
  • the packaging machine 12 described above has numerous advantages.
  • the packaging machine 12 described above allows to change in a particularly rapid manner its operating configuration to create a sealed inner wrapping 3 (first operating configuration illustrated in Figure 12 ) or to create an unsealed inner wrapping 3 (second operating configuration illustrated in Figure 17 ).
  • the above-described packaging machine 12 can be designed from the beginning to produce both a sealed inner wrapping 3 and an unsealed inner wrapping 3 (namely, it can comprise, from the beginning, both the wrapping wheel 30 and the straight wrapping conveyor 33 and the wrapping wheel 39 and the straight wrapping conveyor 41)
  • the above-described packaging machine 12 can be designed to produce only a sealed inner wrapping 3 (namely, it can comprise, from the beginning, the wrapping wheel 30 and the straight wrapping conveyor 33 but not the wrapping wheel 39 and the straight wrapping conveyor 41) and being integrated, subsequently, to produce an unsealed inner wrapping 3, or the packaging machine 12 described above can be designed to produce only an unsealed inner wrapping 3 (namely, it can comprise, from the beginning, the wrapping wheel 39 and the straight wrapping conveyor 41 but not the wrapping wheel 30 and
  • the packaging machine 12 described above allows to change in a particularly rapid manner its operating configuration also to create a conventional outer container (of the type illustrated in Figures 1 and 2 - first and second operating configuration illustrated in Figures 12 and 17 ) or a " zippo " outer container (of the type illustrated in Figures 20 and 21 - third operating configuration illustrated in Figure 24 ).
  • packaging machine 12 described above is relatively inexpensive, since a limited number of components are changed between the various operating configurations.
  • packaging machine 12 described above is particularly compact considering that it allows to create, with few modifications, packs 1 of cigarettes substantially different one from the other.
