Definitions

  • Bobbins are elements, wherein the web material is wound neatly on a core (generally made up of a tube) in shapes that vary, depending on the purpose, from cylindrical to truncated cone shape.
  • bobbins have the disadvantage that only a limited quantity (ion particular length) of web material can be wound on it. Therefore, many machine stops are requested for splicing the web material. During the splice of the material an end of the currently used bobbin is spliced with an end of a new bobbin which replace the bobbin that is about to end.
  • the products produced with the web material comprising the spliced portions of the two webs are typically discarded.
  • the aim of the present invention is to provide a manufacturing machine for producing a strand of material for a smoking article, without the drawbacks described above and which is easy and economical to implement.
  • number 100 denotes, as a whole, a manufacturing machine for producing a strand of material M for a smoking article, in particular for producing a subunit of the smoking article.
  • the manufacturing machine 100 is a filter making machine configured to produce at least a segment of a filter (subunit) of the smoking article.
  • the manufacturing machine is a maker machine configured to produce at least a segment (subunit) comprising tobacco or a substrate forming aerosol.
  • the subunit is achieved by cutting, in particular transversally (more in particular orthogonally to its longitudinal extension) a continuous material strand produced by the manufacturing machine 100.
  • the manufacturing machine 100 comprises two feeding units 101 and 102, a processing unit 103, a forming unit 104 and a switching unit 110.
  • the two feeding units 101 and 102 are each configured to feed a respective web material M, which is the same.
  • the feeding units 101 and/or 102 can also act as a storage unit of the material M.
  • the web material M is the same but a transporting support 105 or 106, on which the web material M is arranged, is different as disclosed in detail below.
  • the fed web material M is illustrated as a line. It is understood that the fed web material M has dimensions (in particular thickness and depth; both measured orthogonal to its longitudinal extension L) which, on the contrary as illustrated, are not null.
  • the processing unit 103 is configured to receive the web material M from the feeding unit 101 or 102 and to process the web material M.
  • the processing unit 103 is configured to subject the material M to treatments in preparation of its gathering for forming the continuous material strand (as disclosed in detail below).
  • the processing unit 103 comprises a crimping device (of known type and not further described or illustrated).
  • the crimping device is configured to provide the web material M with material weakenings, which are configured to promote the subsequent gathering of the material M in the forming unit 104.
  • the material weakenings comprise: a plurality of folds and/or a plurality of cuts and/or incisions.
  • the plurality of fold and/or the plurality of cuts and/or incisions extend parallel to the longitudinal extension of the material M or are arranged according to a predetermined pattern.
  • the cuts and/or incisions extend continuously or intermittently along the longitudinal or transversal extension of the material M.
  • the forming unit 104 is arranged downstream to the processing unit 103.
  • the forming unit 104 is configured to receive the web material M from the processing unit 103 and to form a continuous material strand by gathering the web material M.
  • the forming unit 104 comprises a forming device configured to form a continuous material strand by gathering the web material M received by the processing unit 103.
  • the forming device is of the known type and comprises a forming beam configured to gather the web material M which passes into it and preferably to wrap the continuous material strand with a paper strip so as to achieve a wrapped continuous material strand.
  • the web material M is moved longitudinally along an advancing path AP defined between an inlet station SI (arranged downstream of each feeding units 101 and 102 and upstream of the processing unit 103) in correspondence of which the web material M enters in the manufacturing machine 100 and an outlet station SO of the forming unit 104 in correspondence of which the continuous material strand exits from the manufacturing machine 100.
  • the advancing path AP defines an advancing direction AD of the web material M.
  • the feeding unit 101 is configured to feed the web material M along a feeding direction FD1 drawn it from at least one stack 1.
  • the feeding unit 101 comprises a first transport support 105 on which the web material M is stacked on at least one stack 1 (as schematically illustrated in figure 5 ).
  • the web material M comprises a plurality of folds defined by folding lines 3 which extends transversally, in particular orthogonally, to the longitudinal extension of the web material M. Each fold is made in alternating opposite folding directions FD, so that two subsequent layers obtained by folding the web material M are parallel to each other. In other words, the material M, is "zig-zag" folded. Two subsequent layers obtained by folding the material M are superimposed on top of each other ( figures 5 and 6 ).
  • the stacks 1 are arranged on the transport structure 105 configured to be fed to the manufacturing machine 100 of the tobacco industry.
  • the transport structure 105 is fed to the manufacturing machine 100 through a conveying unit 107 (illustrated schematically in figure 6 ).
  • the longitudinal extension of the web material is parallel to the feeding direction FD1.
  • the feeding unit 102 is configured to feed the web material M along a feeding direction FD2 drawn it from a bobbin.
  • the feeding unit 102 comprises a transporting support 106 on which is arranged the bobbin of the web material M.
  • the transporting support 106 is rotatable around a rotation axis transversal, in particular orthogonal, to the second feeding direction FD2.
  • the transporting support 106 is a different type from the transporting support 105.
  • the transport support 105 being a pallet (also known as skid or storage rack). While the transport support 106 being a shaft for the bobbin (the web material M is wound neatly on a core).
  • the manufacturing machine 100 comprises the switching unit 110 configured to switch selectively from the feeding unit 101 to the feeding unit 102; and vice versa. Therefore, the manufacturing machine 100 is configured for selectively produce the material strand with the web material M fed by the feeding unit 101 or the feeding unit 102.
  • the web material M fed by the feeding units 101 and 102 is of the same type but stored differently. In other words, the transporting supports 105 and 106 are different. In other words, what is different between the material M fed by the two feeding units 101 and 102 is not the material M per se but is the transport support on which it is arranged.
  • the switching unit 110 is an interface (in particular an input interface or an input-output interface) through which an operator can select which feeding unit 101 or 102 activate for feeding the material M on the respective transporting support 105 or 106 to the processing unit 103.
  • the web material M comprises at least one material chosen between: paper, cellulose, non-woven material, tobacco, a substrate for the aerosol formation or a combination of them.
  • the feeding unit 101 is arranged parallel to the processing unit 103 so that a feeding direction FD1 of the feeding unit 101 is parallel, in particular aligned, to the advancing direction AD; while the feeding unit 102 is arranged transversally, in particular orthogonally, to the processing unit 103 so that a feeding direction FD2 of the feeding unit 102 is transversally, in particular orthogonally, to the advancing direction AD.
  • the feeding unit 101 is arranged so that the feeding direction FD1 is parallel to the advancing direction AD. Furthermore, the feeding unit 102 is arranged so that the feeding direction FD2 is transversal, in particular orthogonal, to the advancing direction AD.
  • the manufacturing machine 100 comprises a buffer 108 (optional) arranged between the processing unit 103 and the feeding units 101 and 102.
  • the buffer 108 is arranged aligned with the processing unit 103.
  • the feeding unit 101 is arranged upstream (with reference to the feeding directions FD1 and FD2) to the feeding unit 102, so that the feeding unit 101 is closer to the processing unit 103 than the feeding unit 102.
  • the feeding unit 101 is arranged downstream (with reference to the feeding directions FD1 and FD2) to the feeding unit 102, so that the feeding unit 102 is closer to the processing unit 103 than the feeding unit 101.
  • both feeding units 101 and 102 are arranged transversally, in particular orthogonally, to the processing unit 103, so that both feeding directions FD1 and FD2 of the feeding units 101 and 102 are transversally, in particular orthogonally, to the advancing direction AD.
  • the feeding unit 101 is arranged so that the first feeding direction FD1 is transversal, in particular orthogonal, to the advancing direction AD and the feeding unit 102 is arranged so that the feeding direction FD2 is transversal, in particular orthogonal, to the advancing direction AD.
  • the feeding unit 101 is arranged downstream (with reference to the feeding directions FD1 and FD2) to the feeding unit 102, so that the feeding unit 102 is closer to the processing unit 103 than the feeding unit 101.

  • the manufacturing machine 100 comprising a guiding member 109 arranged between the processing unit 103 and both feeding units 101 and 102.
  • the guiding member 109 is configured to guide the web material M during the direction change from an orthogonal orientation to the advancing direction AD to a parallel orientation to the advancing direction AD.
  • the web material M fed by the feeding unit 101 is fed at a height from the floor (namely the dimension measured orthogonal to the floor on which the manufacturing machine 100 is arranged) which is higher than a height (measured in the same way) at which the web material M is fed by the feeding unit 102.
  • the invention described so far comprises a plurality of advantages.
  • the switching unit 110 to switch selectively from one feeding unit 101 to the other feeding unit 102, or vice versa, in an easy way, without requiring any effort.
  • the invention can also be easily implemented in pre-existing machines 100 without requiring major adaptation interventions, but simply by adding the feeding unit 101 or 102 and eventually the switching unit 110.
