Definitions

  • the present invention relates to a method and to a machine for manufacturing filters for the tobacco processing industry.
  • the present invention relates to a method and to a machine for manufacturing filters for smoking articles (cigarettes) .
  • This continuous rod is therefore, always fed with a continuous motion to a cutting station, to be cut into filter segments of a given length.
  • the patent application with the publication number WO2011148130 describes the manufacturing of coaxial filters, each comprising an inner portion with a particular shape (for example, Figure 1 shows such an inner portion with a star shaped section) and a peripheral portion arranged around the inner portion.
  • the filters are produced by cutting transversely a rod, formed by the combination (obtained through a hollow tube) of two tows of a filtering material, which are treated by means of vapor before being brought into contact with one another.
  • the patent US4291711 describes the manufacturing of coaxial filters starting from a first and a second tow, of different materials, which are combined with one another.
  • the first tow is treated by means of steam and then cooled so as to harden before coming into contact with the second tow.
  • the object of the present invention is to provide a machine and a method which allows, at least partially, the drawbacks of the prior art to be overcome and is at the same time, easy and inexpensive to implement.
  • FIG 1 denotes in its entirety a machine for manufacturing filters 2 of the tobacco processing industry ( Figure 3 ).
  • the machine 1 is adapted to produce filters 2 for cigarettes 3. More precisely, the machine 1 is adapted to produce filters 2 without paper.
  • Each filter 2 comprises a portion 4, which is rod-shaped and comprises (in particular, consists of) a first filter material and a portion 5, which is in contact with the portion 4 and comprises (in particular, consists of) a second filter material.
  • the portion 5 surrounds the portion 4.
  • the portions 4 and 5 extend along the filter 2 (from one end to the other of the filter 2) so that the portion 4 is inside the portion 5.
  • said first and second material differ in some aspects.
  • the first and the second material have colors and/or flavorings and/or filtering capacities different one from the other.
  • the machine 1 ( Figures 1 and 2 ) comprises a feeding assembly 6 for feeding a tow 7 of filtering materials along a path P1 (in a direction A), through a treatment station 8, to an intermediate station 9; a feeding assembly 10 to feed a tow 11 of filtering material along a path P2 (in a direction A) to the intermediate station 9; and a conveying assembly 12, for transporting the tows 7 and 11 from the intermediate station 9 along a path P3 (in the direction A).
  • a combining device 13 is provided in the area of the path P3 (in particular, at the area of the intermediate station 9) to bring (directly) into contact (and bind one with the other) the tows 7 and 11 so as to obtain a combined tow 14.
  • the tows 7, 11 and 14 are fed, respectively along the paths P1, P2 and P3, with a substantially continuous motion.
  • the tows 7 and 11 (which, were cut transversely in successive steps, define the portions 4 and 5) already assume a relative position corresponding to that of the portions 4 and 5 in the filter 2.
  • the tow 11 is arranged around the tow 7 ( Figure 7 ) as the portion 5 is arranged around the portion 4 ( Figure 3 ).
  • tows 7 and 11 comprise, respectively, the first and the second filter material.
  • the machine 1 also comprises a treatment device 15, which is arranged in the area of the treatment station 8 and is adapted to supply heat (in particular, steam) to a hardening substance (typically, triacetin) contained in the tow 7 of filtering materials, and (therefore) activates (making more fluid) said hardening substance; and a treatment device 16, which is arranged along the path P3 (in the area of a treatment station 17) downstream of the combining device 13 to supply heat (in particular, steam) to a hardening substance (typically, triacetin) contained in the tow 11 of filtering materials, and (then) activates (making more fluid) said hardening substance.
  • a treatment device 15 which is arranged in the area of the treatment station 8 and is adapted to supply heat (in particular, steam) to a hardening substance (typically, triacetin) contained in the tow 7 of filtering materials, and (therefore) activates (making more fluid) said hardening substance
  • a treatment device 16 which is
  • the heat (steam) is supplied to the tow 11 when the latter has been combined with the tow 7.
  • the hardening substances of the tows 7 and 11 have the same composition and, in particular, comprise (consist of) triacetin.
  • the treatment device 15 is also adapted to give a given shape to the tow 7 of filtering material.
  • the machine 1 also comprises a cooling device 18, which is arranged along the path P3 (in the area of a cooling station 19) downstream of the treatment device 16 to cool (and, in particular, dry) at least partially, the combined tow 14 and to obtain a rod 20 of hardened filtering material (without paper).
  • a cooling device 18 which is arranged along the path P3 (in the area of a cooling station 19) downstream of the treatment device 16 to cool (and, in particular, dry) at least partially, the combined tow 14 and to obtain a rod 20 of hardened filtering material (without paper).
  • the position of the cooling device 18 is particularly advantageous because it allows the activation of the hardening substances to be accelerated only when the combined tow 14 has already been obtained.
  • the hardening substance of the tow 7 has the possibility of interacting (when still active - not solidified) with the tow 11 and with the hardening substance of the tow 11 itself. More precisely, the steam is given time to take effect before eliminating the same by drying.
  • This aspect allows, in combination with the others previously described, the tows 7 and 11 to bind in a profound way and to solidify (at least partially) together in order to obtain the rod 20 substantially free of inhomogeneities at the interface between the tows 7 and 11.
  • the feeding assembly 6 is adapted to feed the tow 7 of filtering material through an application station 21, which is arranged along the path P1 upstream of the treatment station 8 and where an application device 22 is arranged to provide the tow 7 of filtering material with the respective hardening substance.
  • the tow 7 is also stretched in the area of the application station 21.
  • the feeding assembly 10 is arranged to convey the tow 11 of filtering material through an application station 23, which is arranged along the path P2 upstream of the intermediate station 9 and where an application device 24 is arranged to provide the tow 11 of filtering material with the respective hardening substance.
  • the tow 11 is also stretched in the area of the application station 23.
  • the treatment device 15 is also adapted to give a given shape to the tow 7. Examples of shapes that can be given to the tow 7 are illustrated in US4291711 and in WO2011/148130 .
  • the paths P1 and P2 have respective sections T2 substantially converging (in particular, so as to lead the tow 11 under the tow 7 in the area of the intermediate station 9).
  • the section T2 of the path P1 extends from the treatment station 8 to the intermediate station 9.
  • the paths P1 and P2 also have respective sections T1 substantially diverging one in respect to the other (and arranged upstream of the sections T2)
  • the paths P1 and P2 have respective sections T3 facing each other and arranged upstream of respective sections T1. More precisely, the sections T3 are substantially parallel one to the other. Even more precisely, the sections T1 extend from respective sections T3 to respective sections T2.
  • the machine 1 (in particular, the treatment device 15) comprises a forming beam 25 (which has an inner channel with a cross section that changes along the longitudinal extension of the forming beam itself - of the type known per se) and porous conveyor means 26 (in particular, a porous tape), which extend and can be operated to move along (at least) a section of the path P1. More precisely, the conveyor means 26 are adapted to slide along the forming beam 25 (more precisely, along its inner channel). During sliding, the conveying means 26 are deformed following the profile of the inner channel so as to impose a given shape (typically, round) to the tow 7.
  • a forming beam 25 which has an inner channel with a cross section that changes along the longitudinal extension of the forming beam itself - of the type known per se
  • porous conveyor means 26 in particular, a porous tape

  • the shape of the cross section of the tow 7 is obtained by passing the tow 7 (having a substantially circular section) through a die (which is part of the treatment device 15).
  • the die (known per se and not illustrated) is arranged downstream of the forming beam 25.
  • the aforementioned die has a through hole (through which passes the tow 7 thus deforming) with a (end) cross section of the shape of which the cross section of the tow is needed to be obtained. Therefore, for example, the through hole has a triangular, square or rectangular (end) cross section (or any of the shapes of the inner sections of the rod described in US4291711 and in WO2011/148130 ).
  • the treatment device 15 comprises an application unit 27, which is adapted to blow steam onto the tow 7 through the pores of the conveying means 26 and is arranged in the area of (in some cases, at the end of) an end section of the forming beam 25.

More precisely, the conveying means 30 are adapted to slide along the forming beam 28 (more precisely, along the inner channel 29). While sliding, the conveying means 30 are deformed by following the profile of the inner channel 29 so as to impose a specific shape (in particular, circular) to the tow 11. In particular, the conveying means 30, by sliding along the forming beam 28, wind the tow 11 around the tow 7.

  • the cooling device 18 is adapted to blow air onto the combined tow 14 (through the pores of the conveying means 30).
  • the cooling device 18 is arranged downstream of the application unit 31 in the area of (in some cases, at the end of) an end section of the forming beam 28.
  • a method for manufacturing filters 2 (as defined above) of the tobacco processing industry (in particular filters 2 for cigarettes 3) is provided.
  • the method comprises: a first feeding step to feed the tow 7 of filtering material along the path P1 through the treatment station 8 to the intermediate station 9; a second feeding step to feed the tow 11 of filtering material along the path P2 to the intermediate station 9; and a first treatment step, during which, in the area of the treatment station 8, heat (in particular, steam) is supplied to a hardening substance contained in the tow 7 to activate the hardening substance itself.
  • the first and second feeding step are substantially simultaneous.
  • the method also comprises a conveying step to convey the tows 7 and 11 from the intermediate station 9 along the path P3; and a combining step, to bring (directly) into contact the tows 7 and 11 in the area of the path P3 (in particular, in the area of the intermediate station 9) so as to obtain a combined tow 14.
  • the method comprises a second treatment step, which is subsequent to the combining step and during which, in the area of the treatment station 17 arranged along the path P3, heat (in particular, steam) is supplied to a hardening substance contained in the tow 11 of filtering material, so as to activate the hardening substance itself; and a cooling step, which is subsequent to the second treatment step, during which the tows 7 and 11 coupled in the combined tow 14 are both at least partially cooled (in particular, dried) so as to obtain the rod 20 of hardened filtering material without paper.
  • heat in particular, steam
  • a cooling step which is subsequent to the second treatment step, during which the tows 7 and 11 coupled in the combined tow 14 are both at least partially cooled (in particular, dried) so as to obtain the rod 20 of hardened filtering material without paper.
