Definitions

  • This invention relates to a line and a method for the production of rod-shaped articles of the tobacco industry.
  • rod-shaped articles of the tobacco industry is used not only to denote conventional cigarettes, which are intended to be smoked following the combustion of tobacco, but also new generation cigarettes, which are intended to be smoked following heating of the tobacco or of an alternative substance capable of producing an aerosol.
  • the term "rod-shaped article of the tobacco industry” may also denote the filters used to make what are known as “filter cigarettes”.
  • Some examples of production lines that make cigarettes, in particular filter cigarettes, are known from patent documents WO2005/046365 , US4321050 and US2006201523 .
  • a line for the production of filters, in particular multi-component filters, is known, on the other hand, from patent document EP1787534 , again by way of example.
  • the aim of this invention is to provide a line and a method for the production of rod-shaped articles of the tobacco industry that are free of the above mentioned disadvantages.
  • the reference numeral 1 denotes in its entirety a line for the production of rod-shaped articles 2 of the tobacco industry.
  • rod-shaped articles of the tobacco industry is used to mean either the cigarettes or the filters as specified above.
  • the articles 2, be they cigarettes or filters, are of multi-component type, that is to say, they comprise a plurality of cylindrical segments 3 which are aligned with each other along the respective longitudinal axes X and are wrapped together in a tubular wrap 4 of wrapping material.
  • the tubular wrap 4 placed round all or part of the set of segments 3 is made of paper.
  • the articles 2 may in turn be semi-products to be sent on for further processing, or finished products of the cigarette or filter type.
  • the segments 3 making up each article 2 may be in contact with each other, one after the other (as shown in Figure 1 ) or in one or more pairs of adjacent segments 3, where the segments 3 may be separated by a space.
  • At least one of the segments 3 is a capsule 3a containing a filling material.
  • the filling material may be a material that produces an aerosol, such as tobacco granules or fibres, or an aromatic material - for example in the form of granules consisting of microcapsules containing an aromatic liquid - or a filter material such as activated carbon granules, cellulose acetate fibres, silica gel granules or a material having a cooling effect while smoking the article 2, such as PLA (polylactic acid) granules or fibres.
  • PLA polylactic acid
  • At least one of the capsules 3a may contain tobacco granules or fibres capable of creating an aerosol.
  • At least one of the capsules 3a may contain filter material or PLA granules or fibres.
  • the segments 3 which are not capsules 3a as specified above may contain tobacco, such as shredded tobacco or a crimped and gathered tobacco sheet, for example, or a filter material such as cellulose acetate, for example.
  • the production line 1 comprises a plurality of units 5 for feeding respective segments 3, of which at least one, labelled 5a, is positioned and shaped to supply the aforementioned capsules 3a.
  • the feed units 5 are independent of each other; that is to say, they can be substituted, omitted or moved one by one.
  • the feed unit 5 is positioned and shaped to feed the capsules 3a in an ordered succession.
  • the production line 1 also comprises an assembling unit 6, adapted to make up the sets of segments 3 and to wrap them in the tubular wrap 4 of wrapping material to make the multicomponent articles 2.
  • FIG 2 illustrates a possible embodiment of this invention, in which the assembling unit 6 is fed by four feed units 5, of which only one, positioned in line with the assembling unit 6, feeds the capsules 3a.
  • the assembling unit better illustrated in Figure 3 , comprises a unit 7 for making the capsules 3a and a transfer conveyor 8, which is interposed between the unit 7 for making the capsules 3a and the assembling unit 6 and which is configured to transfer in sequence the capsules 3a in an ordered succession from a pickup station U, located at the outlet of the unit 7 for making the capsules 3a, to a delivery station I, located at the infeed of the assembling unit 6.
  • the unit 7 for making the capsules 3a comprises the following, in succession:
  • the station A is configured to receive from an overhead line 9 a plurality of tubular bodies 10, illustrated in Figure 4 , from which the cylindrical tubular walls of the capsules 3a are formed by multiple transverse cutting.
  • the tubular bodies 10 are made of paper material.
  • the length of the tubular bodies 10 is a multiple of the length of the capsules 3a.
  • the length of the tubular bodies 10 is eight times the length of the capsules 3a.
  • the station A comprises a feed hopper 11 configured to contain the tubular bodies 10 in bulk and to feed them to a train of drums 12 by which the tubular bodies 10 are, in a known manner not described herein, cut into segments whose length is equal to the final length of the capsules 3a and which are then axially offset from each other and then aligned, one after the other, in such a way as to form a succession of segments whose main axis of extension X is perpendicular to the feed direction of the succession.
  • the train of drums 12, fed with a mass of tubular bodies 10, thus delivers to a transfer drum 13 an ordered succession of segments, each defining the cylindrical tubular wall of a capsule 3a.
  • the station A also comprises a device 14 for feeding a continuous web N of wrapping material, from which to make by transverse cutting a plurality of connecting strips used to wrap the respective tubular wraps conveyed in succession by the drum 13.
  • the web “N” may be a single layer of paper or a multilayer material such as, for example, a metal foil and paper laminate.
  • the web N may be perforated.
  • the perforations may be made prior to feeding it (that is at the paper mill) or in-process while it is being unwound by specific perforating means of known type, not illustrated, such as laser devices or mechanical perforators.
  • the station A also comprises a gumming device 15 to apply a layer of adhesive on the web N and a cutting device 16 to divide the web N into connecting strips, as described above.
  • the station A also comprises a receiving drum 17 configured to receive, from the cutting device 16, the succession of connecting strips and, from the transfer drum 13, the tubular segments used to make the capsules 3a. Next, the drum 17 feeds the connecting strips and the segments to a rolling drum 18 in such a way that each connecting strip is applied in cantilever fashion to a respective tubular segment.
  • the rolling drum 18 acts in conjunction with a rolling bed 19 configured to roll each connecting strip around the respective tubular segment.
  • the station A Downstream of the rolling bed 19, the station A comprises a device 20 for closing a first of the two longitudinal ends of the capsules 3a.

  • the closing device 20 comprises a train of horizontal axis feed drums 22, each equipped with a plurality of closing means (not illustrated) moved by a fixed cam (not illustrated).
  • Each closing means comprises a drive rod, slidable in a respective linear guide and engaged with the fixed cam in such a way that during rotation of the feed drum 22, the cam causes the closing means to move with reciprocating translational motion in the direction of the longitudinal axis of the tubular segments with which the capsules 3a are formed.
  • the closing means fold the ends of the connecting strips that protrude from the edges of the tubular segments on which the connecting strips themselves are wrapped and glued.
  • the closing means fold the ends of the tubular segments on which the connecting strips themselves are wrapped and glued.
  • Folding the connecting strips or the segments or both is preferably carried out in sectors - for example in four sectors - in successive steps along the path defined by the train of feed drums 22. In other words, one sector is folded on each feed drum 22 until all the sectors are folded.
  • the feed station A may receive and transfer ready-made empty capsules, that is to say, capsules already provided with the bottom, as specified above.
  • the capsules 3, each provided with the bottom and open at the end opposite the bottom, are picked up by a tapered drum 23, configured to transfer the empty capsules 3a to the filling station R and to modify their orientation from horizontal to vertical with the open end facing up, ready for filling.
  • the filling station R is provided with at least one vertical axis feed drum 24 which in turn comprises a fixed cam (not illustrated) and on which a plurality of filling means 25 is mounted.
  • the filling means 25 each comprise a drive rod (not illustrated) which is slidable in a respective linear guide and which is engaged with the fixed cam in such a way that as the feed drum 24 rotates, the cam mechanism causes a reciprocating translational movement of the filling means 25 along a vertical direction, parallel to the main axis of extension of the succession of capsules 3a as they pass through the filling station R.
  • the closing station C located downstream of the filling station R, comprises a device 26 for closing the second of the two longitudinal ends of the capsules 3a.
  • the second longitudinal end labelled 27 and illustrated in Figure 4 , defines the top of the capsules 3a, closed and ready to be conveyed to the assembling unit 6.
  • the closing device 26 is the same as the closing device 20 described above, except that the feed drums have a vertical axis instead of a horizontal axis.
  • the closing device 26 comprises a train of vertical axis feed drums, each equipped with a plurality of closing means (not illustrated) moved by a fixed cam (not illustrated).
  • Each closing means comprises a drive rod, slidable in a respective linear guide and engaged with the fixed cam in such a way that during rotation of the feed drum, the cam causes the closing means to move with reciprocating translational motion in the direction of the longitudinal axis of the capsules 3a.
  • a tapered drum 28 Downstream of the closing station C there is a tapered drum 28 that is the same as the tapered drum 23 described above.
  • the drum 28 is configured to transfer the full capsules 3a from the closing device 26 to the pickup station U of the assembling unit 6 to modify its orientation from vertical to horizontal.
  • the drum 28 engages the transfer conveyor 8, which comprises at least one transfer drum 29 provided with seats (not illustrated), each adapted to contain a respective capsule 3a.
  • the seats for containing and transporting the capsules 3a are connected to a conventional suction source which is not illustrated.
  • the transfer conveyor 8 comprises a train of transfer drums 29.
  • the train 29 of drums is assembled in modules.
  • the transfer conveyor 8 is a linear conveyor: that is to say, it comprises a conveyor belt trained around at least one pair of (horizontal axis) pulleys.
  • the conveyor belt is provided with seats (not illustrated), each adapted to contain a respective capsule 3a.
  • the seats for containing and transporting the capsules 3a are connected to a conventional suction source which is not illustrated.
  • the transfer conveyor 8 comprises a buffer (storage unit) for accumulating the capsules 3a and whose function is to compensate for any differences in production speed between the unit 7 for making the capsules 3a and the assembling unit 6.
  • the buffer is a buffer of conventional type, not described herein, preferably a FIFO (first in first out) buffer.
  • the transfer conveyor 8 whether provided with the buffer or not, ensures that the capsules 3a produced in situ by the unit 7 are transferred directly and in sequence, in an ordered succession. This simplifies the entire production process of the articles 2. In particular, if the capsules 3a have an assembly direction, their bottom-to-top orientation is thus maintained.
  • the integrity of the capsules 3a is also maintained, since their storage in a mass and subsequent singulation could easily damage the capsules 3a, especially their longitudinal ends, delicately folded during production.
  • the unit 7 for making the capsules 3a is not provided and the transfer conveyor 8 of the unit 5a for feeding the capsules 3a receives the capsules 3a from an overhead feed line or hopper and transfers them to the delivery station I located at the infeed of the assembling unit 6.
  • the transfer conveyor 8 is configured to pick up the capsules 3a from a first path, along which the capsules 3a advance in a direction transversal to their longitudinal axis, and to deliver the capsules to a second path, along which the capsules 3a advance in a direction transversal to their longitudinal axis.
  • the transfer conveyor is configured to pick up the capsules 3a from a first path, along which the capsules advance in a direction transversal to their longitudinal axis, and to deliver the capsules 3a to a second path, along which the capsules 3a advance in the direction of their longitudinal axis.
  • the assembling unit 6 comprises a modular section 30 for combining the segments 3 in groups, where each module 31 is fed by at least one respective feed unit 5 and is provided with a plurality of drums 32 for feeding the segments in a direction transversal to their longitudinal axis and in which at least two adjacent modules 31 combine the segments by means of two respective drums 32 operatively coupled to each other.
  • the assembling unit 6 comprises a wrapping section, equipped with a wrapping device 33 for wrapping a wrapping material around the combination of segments.
  • the module 31 that is fed with the capsules 3a by the transfer conveyor 8 (hence by the feed unit 5a) is simultaneously fed by a further feed unit 5 equipped with a hopper, while each of the remaining modules 31 is fed by a single feed unit 5 equipped with a hopper.
  • the wrapping device 33 comprises a rolling unit 34 through which the segments, made up of groups, are wrapped in a sheet of wrapping material, in particular paper, during a rolling motion of the segments themselves about their longitudinal axis.
  • the wrapping device of the assembling unit comprises a forming beam along which the segments, made up of groups, advance aligned with one another along the respective longitudinal axes and wrapped during their advance by a continuous web of wrapping material, in particular paper, for forming a rod.
  • rod-shaped articles of the tobacco industry be they cigarettes or filters, which comprise a plurality of component segments, at least one of which is a (cylindrical) capsule, in turn comprising a tubular side wall, a closed top end and a closed bottom end and containing inside it a filling material, specifically granules (for example, of tobacco) or fibres (for example, of PLA).
  • a filling material specifically granules (for example, of tobacco) or fibres (for example, of PLA).

  • the transfer of the capsules 3a comprises picking up the capsules 3a from a first path, along which the capsules 3a advance in a direction transversal to their longitudinal axis X, and delivering the capsules 3a to a second path, along which the capsules 3a advance in a direction transversal to their longitudinal axis X.
  • the transfer of the capsules 3a comprises picking up the capsules 3a from a first path, along which the capsules 3a advance in a direction transversal to their longitudinal axis X, and delivering the capsules 3a to a second path, along which the capsules 3a advance in the direction of their longitudinal axis X.
  • the step of wrapping the wrapping material around the combination of segments 3 is performed in a rolling unit 34 through which the segments 3, made up of groups, are wrapped in a sheet of wrapping material, in particular paper, during a rolling motion of the segments 3 about their longitudinal axis X.
  • the step of wrapping the wrapping material around the combination of segments 3 is performed in a forming beam along which the segments 3, made up of groups, advance aligned with one another along the respective longitudinal axes X and wrapped during their advance by a continuous web of wrapping material, in particular paper, for forming at least one rod.
