Definitions

  • This invention addresses the technical sector of smoking articles having a cavity.
  • this invention relates to a machine and a method for producing smoking articles having a cavity.
  • This invention also relates to a method and a kit for modifying an existing machine for making smoking articles having a cavity.
  • heating articles is used to mean articles of various kinds such as, for example, traditional filter cigarettes or articles of the “heat not burn” type (HNB, where the article is only heated and not burnt), or rods, that is to say, sub-units of these articles.
  • HNB heat not burn
  • Known in the prior art are smoking articles provided with a cavity, for example cigarettes comprising a cavity at the respective filter.
  • the cigarette rods are joined to filter plugs which are already provided with a cavity and which are then cut.
  • the filter plugs with cavity are made in a specific machine, known as combiner, which assembles all the different filter rods, alternating them with cavities, to form a filter plug.
  • This invention has for an aim to overcome the above mentioned drawbacks.
  • this invention allows smoking articles having a cavity to be made in a particularly simple, quick and inexpensive manner compared to the prior art.
  • the numeral 1 denotes a machine for making smoking articles having a cavity according to this invention.
  • drying articles is used to mean articles of various kinds such as, for example, traditional. filter cigarettes or articles of the "heat not burn” type (HNB, where the article is only heated and not burnt), or rods, that is to say, sub-units of these articles.
  • HNB heat not burn
  • Figures 2-9 show filter cigarettes during the steps in their production.
  • the machine 1 comprises: a picking drum 2 having at least one seat (preferably a plurality of seats) for conveying a full filter rod S (that is, a rod without a cavity) having a multiple length (for example, a quadruple length) along a path); and a first cutting assembly 3 (comprising at least one blade) for cutting the full filter rod S having a multiple length into two filter units F (preferably identical).
  • the machine 1 also comprises a combining drum 4 that: receives in a seat of it two rods T comprising tobacco axially aligned and spaced from each other, and receives, in the same seat, the two filter units F interposed between the two rods T comprising tobacco.
  • the machine 1 also comprises separation means 5 (see Figures 2-4 ) downstream of the first cutting assembly 3 (preferably associated with the combining drum 4, as in the case illustrated) for separating the filter units F from each other in such a way that each one contacts a rod T comprising tobacco (at the respective ends thereof) and in such a way that an empty space V is formed between the two filter units F.
  • the empty space V between the two filter units F (distance) is equal to the longitudinal dimensions of the two cavities C to be obtained (one for each smoking article A, preferably identical to each other).
  • the machine 1 also comprises a wrapping unit 6 for completely wrapping with a wrap I the two filter units F and the empty space V between the filter units F and partially wrapping the two rods T comprising tobacco for connecting them to the filter units F (this being the operation known as "rolling", see Figures 6 and 7 ).
  • the machine 1 also comprises a second cutting assembly 7 for transversally cutting the wrapped wrap I at said empty space V in such a way as to define a cavity C for each filter unit F wrapped by the wrap I and adjacent to the filter unit F.
  • a cutting line 70 is represented as a solid line.
  • the cavity C is shown in Figures 7-9 .
  • the machine 1 according to the invention allows smoking articles A having a cavity C to be made without using a dedicated machine 1 (combiner) to form the filter plugs provided with cavities.
  • the machine 1 according to the invention is therefore economical and structurally simple compared to prior art solutions.
  • the separation means 5 are associated with the combining drum 4 (that is to say, they operate in proximity thereto or are part of it); alternatively, the separation means 5 might be associated with a different drum that is also downstream of the first cutting assembly 3 and upstream of the unit for feeding the wrap I.
  • the separation means 5 comprise pneumatic means (air taken in or blown out).
  • the separation means 5 comprise at least two suction supports 50, arranged at the seat and configured for axially moving each filter unit F in such a way that the empty space V is arranged between the two filter units F (see Figures 2-4 ).
  • the separation means 5 comprise at least two motorized rollers, arranged externally to the combining drum 4, each being able to axially move a filter unit F in such a way that the empty space V is arranged between the two filter units F.
  • a mass of full filter rods S of multiple (for example, quadruple) length is contained in a hopper 20 which has a bottom outlet opening coupled to the picking drum 2 (which has peripheral suction seats for the filter rods S of multiple length).
  • the picking drum 2 acts in conjunction with cutting means 21 (in this case comprising two rotary blades) for cutting the full filter rods S of multiple length transversally so as to obtain double-length filter rods S, as described above.
  • cutting means 21 in this case comprising two rotary blades
  • the double-length filter rods S are transferred from the picking drum 2 to a transit drum 30 which is provided with peripheral suction seats.
  • the double-length filter rods S are transferred to a first cutting drum 31 which is provided with peripheral suction seats and which acts in conjunction with the first cutting assembly 3 (comprising a rotary blade) which cuts each filter rod S into two filter units F (preferably identical).
  • the separate but axially adjacent filter units F are then transferred to a first infeed station 41 of the combining drum 4 provided with peripheral suction seats.
  • a second infeed station 42 of the combining drum 4 arranged downstream of the first infeed station 41 along a feed path, two rods T comprising tobacco are fed into each seat (by a feed drum 43) in such a way that the rods are axially aligned, axially spaced and external to the filter units F.
  • the filter units F and the rods T containing tobacco are all axially aligned (since they are housed in the same seat).
  • each seat contains a group G formed of two rods T comprising tobacco, two filter units F and an empty space V between the filter units F.
  • the groups G thus formed are transferred to a coupling drum 60 provided with peripheral suction seats for the groups.
  • a feed unit for feeding a wrap I (a connecting strip which is gummed, that is, provided with adhesive) for each group G and for applying it as described above (so as to wrap completely the two filter units F and the empty space V between the filter units F and partially the two rods T comprising tobacco in order to connect them to the filter units F).
  • the groups G provided with the wraps I are transferred to a rolling drum 61 where wrapping around the groups G is completed by the wrapping unit 6.
  • the machine 1 comprises a second cutting drum 71, where a second cutting assembly 7 cuts each group G (preferably centrally) where the empty space V between the two filter units F is, to form two juxtaposed smoking articles A (in the case illustrated, filter cigarettes) having a cavity C.
  • the end section of the machine 1 comprises a tip-turning drum 8, where what is known as "tip-turning" occurs, to pass from two juxtaposed rows of smoking articles A, oriented mirror symmetrically, to a single row of smoking articles A oriented in the same direction (where the spacing is obviously half of that of the two juxtaposed rows), as shown in Figure 9 .
  • This invention also relates to a method for producing smoking articles A having a cavity C, comprising the steps of:
  • Figure 9 shows smoking articles A (cigarettes) which, after being cut, have been "tip-turned” so that both are oriented in the same direction, as described above.
  • the step of spacing the two filter units F comprises the sub-step of moving the two filter units F axially away from each other in such a way that an empty space V equal to the sum of the cavities C to be obtained is defined between them (that is, equal to the sum of the cavities C adjacent to each filter unit F).
  • the step of feeding a wrap I comprises the sub-step of feeding a wrap I with a gram weight of between 45 and 100 g/m 2 .
  • this forms smoking articles A where the wrap I is located at the end that is intended to come into contact with the mouth of a user (smoker) and where the thickness of the wrap I is greater than that in prior art solutions (usually between 30 and 40 g/m 2 ). That way, the wrap I is not damaged despite coming into contact with the user's mouth.
  • This invention also relates to a smoking article A obtained with a method as described above (see Figure 9 , where 2 are shown). More specifically, the article comprises: a rod T comprising tobacco T; a filter unit F, axially in contact with the rod T comprising tobacco, and a wrap I that wraps partially the rod T comprising tobacco and completely the filter unit F, in such a way as to protrude from the filter unit F to define a cavity C.
  • the wrap I has a gram weight of between 45 and 100 g/m 2 .
  • the invention also relates to a method for modifying an existing machine 1 (what is known as a filter tip attachment) for making smoking articles A having a cavity C, where the existing machine comprises:
  • the modifying method according to the invention comprises the following steps:
  • the method described above allows modifying an existing machine 1 (what is known as a filter tip attachment) with a few simple and inexpensive modifications to make it suitable for making smoking articles A having a cavity C.
  • the invention also comprises the reverse method to return the machine 1 to the initial conditions, comprising the following steps:
  • the invention further relates to a kit 3, 5 for modifying an existing machine for producing smoking articles A having a cavity C, wherein the existing machine comprises:
  • the kit 3, 5 comprises:
