Definitions

  • Forms of embodiment described here concern an apparatus and method for making up packets for smoking articles, such as for example, but not exclusively, cigarettes.
  • the exit wheel can rotate around an axis of rotation to move a plurality of gripping heads along a predefined path between the entrance station and the exit station.
  • Each gripping head is provided to receive a respective packet of cigarettes having a longitudinal axis and smaller longitudinal walls, each of which defined by a corresponding external longitudinal tongue or lateral wing, and by an internal longitudinal tongue.
  • the exit wheel receives each packet at the entrance station with the corresponding external longitudinal tongues or lateral wings in the open position, that is, raised and inclined: the external longitudinal tongues must be glued to the internal longitudinal tongues to achieve at least one step of making up the packet.
  • each gripping head includes folding elements to fold, at the entrance station and at the moment the packet is inserted into the corresponding gripping head, with the transfer wheel stationary, each of the open lateral wings, in a closed position in contact against the corresponding internal longitudinal tongue.
  • the folding elements are also provided to hold the packets, preventing them from falling out of the respective gripping heads during the rotation of the wheel along the predefined path.
  • This known apparatus provides that the open lateral wings are suitably folded before the packet is fed through the predefined path and also all the operations to be performed on the lateral wings and/or on the internal longitudinal tongues, in particular gluing, are completed at the entrance station.
  • This known apparatus therefore has the disadvantage that it supplies a reduced productivity and needs to position a plurality of operating units at the entrance station, which is already relatively crowded with other operating units.
  • Another disadvantage of this known apparatus is the presence, on board the exit wheel, of the folding elements in each gripping head: considering the fact that the exit wheel is in rotational movement and that therefore it takes the gripping heads with it in rotation, this increases the rotational inertia of the exit wheel itself, making it expensive, complex and difficult to drive and control it.
  • a packaging or forming wheel that carries packets with open smaller lateral wings, packets that are disposed with said wings radially more external;
  • the adhesive distribution means are disposed between the packet support and folding means and the conveyor means
  • the packet support and folding means receive the packets with the open wings from the forming wheel and, following the disposition with wings radially toward the outside of the packet in the forming wheel, immediately engage the open wings of the packets, folding them and pressing them until they contact the main body of the packet, in particular by folding the panels backward with respect to the direction of feed, that is, the radial direction of the wheel. Therefore, as the main effect, they support the packets bilaterally through friction and, as a collateral effect, they fold the panels.
  • the panels themselves re-open, rotating forward, due to elastic return, when they are no longer stressed by the packet support and folding means, in order to receive the glue; only later are they folded definitively, thanks to the means for opposing the elastic return and the conveyor means.
  • This known device can have the disadvantage that the linear transfer means downstream of the forming wheel impart a considerable acceleration for the movement of the packets which could deform them and crush them.
  • Document EP-A- 1.321.364 is also known, which describes an apparatus for making up packets of cigarettes of the type in question, provided with an exit wheel equipped with gripping heads, each provided with folding elements.
  • the external lateral wings are folded on the internal longitudinal tongues by folding elements provided in each gripping head during the rotation of the transfer wheel along the predefined path in an intermediate position downstream of the entrance station and upstream of the exit station.
  • This Icnown apparatus also provides a first station for upending the packet by 90°, immediately downstream of the entrance station, and a second station for upending the packet by 90°, immediately upstream of the exit station.
  • the Icnown apparatus provides, downstream of the first upending station, a glue distribution station to distribute glue onto the internal longitudinal tongues and a subsequent folding station, upstream of the second upending station, to fold the open lateral wings in contact against the internal longitudinal tongues.
  • This Icnown solution also suffers the disadvantage of excessive rotational inertia, deriving from the presence of the folding elements provided in the gripping heads on board the exit wheel in continuous rotation.
  • the presence of the folding elements for each gripping head entails high investment costs, difficulties in assembly, need for maintenance and high frequency of repairs and replacements.
  • an apparatus for making up packets for smoking articles.
  • the apparatus includes:
  • a packet transfer wheel able to rotate step-wise around an axis of rotation to move packets along a transfer path between an entrance station and an exit station of the packet transfer wheel;
  • a packaging wheel upstream of the packet transfer wheel, able to rotate stepwise around an axis of rotation parallel to the axis of rotation of the packet transfer wheel, said packaging wheel being configured to supply radially, to the entrance station of the packet transfer wheel, a succession of packets to be completed by means of subsequent workings;
  • a glue distribution station provided to distribute glue to the packets moved along the transfer path.
  • the apparatus includes:
  • a packet conveying station configured to receive, from the packet transfer wheel, packets on which the glue has been distributed and
  • At least a folding device provided downstream of the exit station, outside the transfer path, configured to fold components to be glued of the packets to be made up, before they are received by the packet conveying station.
  • a method for the making up of packets for smoking articles includes:
  • the method includes: - folding, downstream of the exit station and outside the transfer path, components of the packets to be made up received from the transfer packet wheel.
  • the apparatus and method according to the present description are not affected by the disadvantage of excessive rotational inertia, nor by problems of assembly, maintenance, repairs, machine stoppages etc., that could derive from the presence of the folding elements provided in each of the gripping heads on board the rotating transfer wheel.

  • Figs. 1, 2 and 3 are used to describe forms of embodiment of an apparatus 10 for making up packets 100 for smoking articles 102 (fig. 7).
  • Examples of possible smoking articles are cigarettes, cigars or similar or comparable smoking articles.
  • the apparatus 10 includes a packet transfer wheel 12 provided with an entrance station 14 and an exit station 16, between which a predefined transfer path P develops.
  • the packet transfer wheel 12 can rotate around an axis of rotation Y (figs. 4 and 5), as indicated by the arrow R in fig. 1 (for example clockwise rotation), in order to move a plurality of packet gripping heads 18 along the predefined transfer path P.
  • Forms of embodiment described here therefore provide to move the packets 100 along the transfer path P between the entrance station 14 and the exit station 16 of the packet transfer wheel 12.
  • the packet transfer wheel 12 can be advantageous, in that it allows to move packets 100 taken singularly one by one from the packet gripping heads 18, and not packets 100 linearly moved together packed, that would be subjected to a considerable acceleration that could deform and crush them.
  • the transfer path P can be a circular path, for example an arc of a circle, that develops between the entrance station 14 and the exit station 16.
  • the entrance stations 14 and exit stations 16 can be in diametrically opposite positions on the packet transfer wheel 12.
  • the transfer path P can, for example, concern an angular sector of 180° of the packet transfer wheel 12, where an angle of 0° is taken as reference in correspondence to the entrance station 14.
  • the entrance station 14 and the exit station 16 are in any other reciprocal angular position, not diametrically opposite on the packet transfer wheel 12 and the transfer path P can, for example, concern a different angular sector, for example less than 180°, for example from 30° to 150°, or greater than 180°, for example from 210° to 330°, or other angular positions, according to needs.
  • the axis of rotation Y of the packet transfer wheel 12 can be horizontal, while in other implementations it can be vertical.
  • fig. 1 is used to describe forms of embodiment in which the axis of rotation Y of the packet transfer wheel 12 is horizontal and therefore the packet transfer wheel 12 is located vertical.
  • the packet transfer wheel 12 can, for example, be made to rotate step-wise, where the rotation steps can be coordinated with the angular sectors affected by specific workings or operations, such as entrance, gluing and exit of the packets 100.
  • an actuator can be provided for the rotation of the packet transfer wheel 12.
  • the actuator can include a motor that can be an electric motor, in particular an electric step motor, or servomotor, for example provided with a position transducer, such as an encoder, in particular a rotary encoder.
  • Each packet gripping head 18 of the packet transfer wheel 12 can be configured to receive and hold a respective packet 100 of smoking articles 102 and transport it in a stable way from the entrance station 14 to the exit station 16, along said transfer path P.
  • the packet transfer wheel 12 can be constrained to a support or work plane 1 1, (figs. 4 and 5).
  • the support plane 1 1 can be provided vertical or horizontal depending on the spatial disposition of the packet transfer wheel 12.
  • the packet transfer wheel 12 can be attached to the support plane 1 1, for example cantilevered, by means of a central support hub 13 (see figs. 4 and 5), inside which, for example, actuation, feed, regulation and control components of the packet transfer wheel 12 and/or its components and/or other components operatively associated to the packet transfer wheel 12 can be provided.
  • a central support hub 13 see figs. 4 and 5
  • a packaging or forming wheel 20 can be provided, upstream of the packet transfer wheel 12, which can rotate around an axis of rotation, for example parallel to the axis of rotation Y of the packet transfer wheel 12, as indicated by the arrow R' of rotation of the packaging wheel 20 (for example anti-clockwise rotation).
  • the packaging wheel 20 can be configured to rotate step-wise, advantageously synchronized with the step-wise rotation of the packet transfer wheel 12.
  • the packaging wheel 20 can be configured to supply, in the entrance station 14 of the packet transfer wheel 12, a succession of packets 100 for smoking articles 102 to be completed by means of subsequent workings, such as gluing one or more of their components 104, 106.
  • the packaging wheel 20 can supply the packets 100 radially to the packet transfer wheel 12 (see for example fig. 1). Therefore, a packet gripping head 18 of the packet transfer wheel 12 can receive, at the entrance station 14, a packet 100 for smoking articles 102 from the packaging wheel 20, for example radially (see for example fig. 1).
  • the present invention provides that, compared with the state of the art described in WO-A-2010/1 19472, the linear transfer means at the exit of the packaging or forming wheel are substituted by the packet transfer wheel 12, with the advantage, as discussed above, of preventing the linear accelerations that risk deforming and crushing the packets, since the structure of the packet transfer wheel 12, which advantageously provides individual seatings in which the packets are housed individually, and the rotatory movement of which keep the packet from deforming.
  • a packaging wheel 20 may not be provided upstream and it can be provided that the packet transfer wheel 12 is a wheel configured to also carry out the composition of packets, assembling, in packets ready to be glued and completed in the packaging, the various components that are received from the wheel, such as for example groups of cigarettes already wrapped in an inner wrapping, ribs and external wrappers.
  • the entrance station 14 can be defined by any intermediate station of the packet transfer wheel 12 also configured for the composition of packets, at which, on each occasion, the assembled packets are presented, with the open components to be folded, ready to be glued to complete the packaging.
  • the apparatus 10 includes a glue distribution station 22 configured to distribute glue to the packets 100 for smoking articles 102 (fig. 1).
  • the glue distribution station 22 can be configured to distribute glue along the transfer path P which the packets 100 travel on, transported by the packet gripping heads 18 of the packet transfer wheel 12.
  • the glue distribution station 22 can be outside the packet transfer wheel 12 and can be disposed along the transfer path P.
  • the glue distribution station 22 can be disposed between the entrance station 14 and the exit station 16, along the transfer path P, for example in a median position. Forms of embodiment described here therefore provide to distribute glue, between the entrance station 14 and the exit station 16, to the packets 100 moved along the transfer path P.
  • the glue distribution station 22 can be disposed in correspondence with an angle of 90° downward (that is, negative), with respect to the entrance station 14.
  • the exit station 16 can be disposed in correspondence with an angle of 180° downward (that is, negative), with respect to the entrance station 14.

  • the glue distribution station 22 can be disposed at 30°, 45°, 60°, 120°, 135°, 150° downward, or in any intermediate angular position between these angular values.
  • the glue distribution station 22 can be disposed in correspondence to the entrance station 14.
  • the glue distribution station 22 can be disposed in correspondence with the exit station 16.
  • the apparatus 10 also includes a packet conveying station 24, disposed downstream of the exit station 16 and outside the packet transfer wheel 12, and therefore outside the transfer path P, along which the packets 100 for smoking articles 102 are conveyed along a conveying path C.
  • the packet transfer wheel 12 can supply the packets 100 to the packet conveying station 24 in a radial direction M.
  • the packets 100 can be expelled from the exit station 16 in the radial direction M (figs. 1, 2, 3 and 10).
  • the packet conveying station 24 can be configured to receive the packets 100 for smoking articles 102 exiting from the exit station 16 and on which glue has already been distributed, in order to glue the components 104, 106 of the packet which need this work, suitably folded, and to convey them along said conveying path C.
  • a packed feed configuration can be provided for example, along the conveying path C, in which the packets 100 are made to advance in a row one after the other.
  • the packets 100 can be moved discretely, that is, separated from each other (fig. 10).
  • the conveying path C can be linear, and in particular it can be a linear and radial direction with respect to the packet transfer wheel 12, that is, it can be aligned with the radial direction M of expulsion (see fig. 1 for example), or at least partly circular. In other variants, the conveying path C can be transverse to said radial direction M of expulsion. For example, the conveying path C can be orthogonal to the radial direction M of expulsion (fig. 10), that is, it can be parallel to a direction tangential to the packet transfer wheel 12 in correspondence to the exit station 16.
  • the packet conveying station 24 is configured to glue and also consolidate and stabilize, along the conveying path C, the gluing of the packets 100 for smoking articles 102 received from the exit station 16 of the packet transfer wheel 12.

  • the length of the conveying path C and/or the speed of feed of the packets 100 along the conveying path C can be sized to supply a sufficient passage and staying time so that, as well as gluing, there is also consolidation and stabilization of the gluing.
  • the packet conveying station 24 can be associated to an entrance mouth 34, which can receive the packets 100 exiting from the exit station 16, in particular once these have been expelled from the gripping heads 18.
  • the entrance mouth 34 can be comprised in the packet conveying station 24, or can be separate from the packet conveying station 24, upstream thereof.
  • the packet conveying station 24 can be provided with a conveying channel 25, through which the packets 100 are made to advance to be subjected to the gluing, consolidation and stabilization of the gluing.

  • the feed device 27 can include mobile transport elements 39 disposed opposite and distanced with respect to each other, in order to define a passage gap L (see fig. 1 for example) essentially coinciding with a transverse size D of the packets 100, in order to allow the feed, essentially through drawing, of the packets in series arriving from the entrance mouth 34.

  • the operation of folding the lateral wings 104 takes place only after the holding device 40 has been activated to allow the expulsion of the packet 100 from the exit station 16.

  • the second lateral wing 104 can be folded, abutting against the fixed folding element 30 thanks only to the advance caused by the thruster 32, once the packet 100 has left the exit station 16, or the lateral thrust caused by the mobile folding element 28, or a combination of these two actions, which can take place simultaneously or in sequence, first the action of the thruster 32 and then that of the folding device 26.
  • the action of the thruster 32 can not only cause the expulsion of the packet 100 from the exit station 16 but, once expulsion is complete, it can also be sufficient to, or continue to, cause the packet 100 to be introduced into the entrance mouth 34 of the packet conveying station 24 and, for example, to be gripped by the corresponding feed device 27 (see for example fig. 3).
  • the drive travel of the thruster 32 can be bigger than the travel needed to expel the packet 100 from the packet gripping head 18 at the exit station 16 (fig. 2), and can be sufficient to thrust the packet 100 along the conveying path C, for example toward the entrance mouth 34 (fig. 3), or toward other transport systems, described for example using fig. 10.
  • the lead-in surface of the entrance mouth 34 can facilitate the introduction of the packets 100, preventing stoppages or blockages of the material, in particular of the lateral wings 104. This is because, as discussed above, the packets are disposed in the transfer wheel 12 with the lateral wings more internal radially, so that they are folded forward with respect to the radial direction of the transfer wheel 12, and providing the lead-in shape of the entrance mouth 34 facilitates the introduction of the packets 100, even if they have the lateral wings folded forward.
  • the folding device 26, in particular for example using the mobile folding element 28, keeps the first lateral wing 104 folded until it goes into contact stably, for example sliding tangentially, against the lateral edge 33. Once this stable contact has been obtained, the first lateral wing 104 maintains the condition imposed by the folding device 26, that is, folded in contact against the respective internal longitudinal tongue 106, gluing itself thereto thanks to the presence of the glue previously distributed by the glue distribution station 22.
  • the packet 100 with the lateral wings 104 kept folded by the fixed edge 31 and the lateral edge 33, is taken by the feed device 27 which moves the packets 100 along the conveying path C, keeping the folded lateral wings 104 glued and allowing to consolidate and stabilize the gluing.

  • the pockets 62 are configured to keep the lateral wings 104 inside them, stably in the folded condition, so as to determine the gluing with the internal longitudinal tongues 106 and the consolidation and stabilization of the gluing.
  • the pockets 62 can have at least one size mating with the packets 100, in particular for example they can have a width essentially coinciding with a transverse size, in this case the width D, of the packets 100.
  • the conveyor belt 60 with pockets can define the conveying path C, which can for example be transverse, in particular orthogonal to the radial direction M of expulsion. If the packet transfer wheel 12 lies on a vertical plane, hence with a horizontal axis of rotation Y, the conveyor belt 60 with pockets, and hence the conveying path C defined by it, can therefore be vertical.
