Definitions

  • the present invention relates to an apparatus and method for combining components for the production of smoking articles.
  • Apparatus and processes for manufacturing smoking articles consisting of a plurality of components are known in the art.
  • a rolling process may be used, in which the smoking articles and components are substantially perpendicularly aligned with respect to the direction of travel.
  • a linear process may be used, in which the components are substantially longitudinally aligned along the direction of travel.
  • a combination of the two processes is used, for example, the combining may be carried out as a rolling process and the overwrapping may be carried out as a linear process.
  • known apparatus and manufacturing processes are not suitable for manufacturing smoking articles comprising a component made of a material which cannot be cleanly cut with mechanical cutting means, such as a conventional knife or blade.
  • the apparatus and method of the present invention is particularly, but not exclusively, suitable for manufacturing smoking articles, wherein one of the components is a combustible heat source or fuel element, for example a carbonaceous heat source.
  • a method for combining two or more different components for the production of smoking articles comprising the steps of: feeding a stream of components along a moving delivery path; compacting the stream of components into groups of two or more different components, each group corresponding to a discrete un-tipped smoking article, wherein the components within a group abut one another and wherein there is a predefined space between a leading group of components and a trailing group of components; wrapping the components in a web of material; and cutting the web of material in each space between groups of components.
  • the non-cleanly-cuttable component is a component which cannot be cleanly cut with conventional mechanical cutting means.
  • the component may comprise a brittle material or a material having a tendency to splinter, crumble or fragment when cut with a conventional blade.
  • the non-cleanly-cuttable component is adjacent the space between two groups of components.
  • An un-tipped smoking article comprises all components for a smoking article, that is, the entire number and all the types of components for a smoking article, except for a smoking article tip, such as a mouthpiece and a wrapper.
  • the non-cleanly-cuttable component and the tip are at opposite ends of the smoking article.
  • the two or more different components may comprise a non-cleanly-cuttable component plus one, two, three, four, five or more further components.
  • the two or more different components comprise a non-cleanly-cuttable component plus two, three or four components.
  • the two or more different components comprise a non-cleanly-cuttable component plus three components, one component of a first type and two components of a second type.

  • vibrating bowl is used to supply the (pre-cut) heat sources onto the belt 203e.
  • indexing wheel 203f rotates and supplies the heat sources onto the vacuum belt 209.
  • indexing wheel 203f The desired spacing and ordering of the various components on vacuum belt 209 and the number of fixed fingers on indexing wheel 203f will depend on the structure of the resulting smoking article and also on the later processes involved in manufacturing. In some arrangements (see, for example, Figure 3 discussed below), a regular spacing between components will be required. That is, the same space between one component and the next component will always be needed. This is set by the indexing wheels 203f, 205f, 207f. In particular, for the arrangement shown in Figure 3 , four fixed fingers are provided on indexing wheel 203f. The indexing wheel 203f delivers a controlled number of heat sources onto vacuum belt 209 from continuous supply from belt 203e. For the Figure 3 arrangement, one heat source is provided onto vacuum belt 209 at a time and there is equal spacing between heat sources.
  • Figure 3 shows one possible order for the components on vacuum belt 209.
  • the components are simply in the order that they will be positioned in the finished un-tipped smoking articles. That is: heat source 203, then aerosol-generating substrate 205, then expansion chambers 207, then another heat source 203, then another aerosol-generating substrate 205, then further expansion chambers 207 and so on.
  • the scissor symbols in Figure 3 indicate where the paper web will be cut at blade 223 or further downstream. In Figure 3 , the spacing between components of the same type is indicated at 301.
  • FIG. 3 The order shown in Figure 3 is advantageous because it allows flexibility of the heat conducting element length and position, and it allows for increased accuracy.
  • a double length rod is formed, which is then cut in two, has a double length filter mouthpiece inserted between the two single length rods and a double length of tipping paper applied.
  • a turning drum may be provided downstream of the compacting means, before the tipper. The turning drum takes a continuous line of un-tipped smoking articles and rotates alternate un-tipped smoking articles, thereby allowing a double length filter mouthpiece to be inserted between the two single length un-tipped smoking articles, as in existing processes.
  • Figure 4 shows another possible order for the components on vacuum belt 209.
  • the components are ordered to create two smoking article rods at a time, one facing forward, one facing rearward. That is: heat source 203, then aerosol-generating substrate 205, then expansion chambers 207, then further expansion chambers 207, then another aerosol-generating substrate 205, then another heat source 203, then a third heat source 203 and so on.
  • heat source 203 then aerosol-generating substrate 205, then expansion chambers 207, then further expansion chambers 207, then another aerosol-generating substrate 205, then another heat source 203, then a third heat source 203 and so on.
  • indexing wheels 203f, 205f and 207f of feeding means 203a, 205a and 207a are arranged to supply the components onto vacuum belt 209 with two different spacings between components of the same type (as discussed above).
  • the first spacing between heat sources is shown as 401.
  • the second spacing between heat sources is shown as 403. (There are corresponding spaces (not labelled) between other components of the same type.)
  • the first spacing 401 is the spacing between heat sources in one double-length un-tipped smoking article.
  • the second spacing 403 is the spacing between heat sources in adjacent double-length un-tipped smoking article.
  • the vacuum belt 209 moves the components, in their desired positions, towards compacting means 210. Suction is applied from underneath belt 209 which assists to adhere the components to the belt.
  • Figure 5 shows one exemplary embodiment of compacting means 210 of Figure 2 .
  • the components enter the compacting means at 501 on belt 209 and exit the compacting means at 503 on belt 221.
  • the components are shown in the order of Figure 4 , that is, to create two un-tipped smoking articles at a time, one facing forward, one facing rearward.
  • any suitable component ordering is possible.
  • compacting means 210 includes three wheels 211, 213 and 215.
  • First wheel 211 is used to separate the plurality of components into groups of components.
  • first wheel 211 includes seven fixed, circumferentially-spaced fingers 505a and is arranged to rotate in a clockwise direction.
  • Second wheel 213 is used to compact the components within each group.
  • second wheel 213 includes eight circumferentially-spaced moveable thick fingers 507a and is arranged to rotate in an anti-clockwise direction.
  • Each moveable thick finger 507a is driven by a cam 507b, rather than being fixed to wheel 213, so that movement of each thick finger 507a, relative to wheel 213, is possible.
  • Third wheel 215 is used to set the spacing between each group of components.
  • third wheel 215 includes eight circumferentially-spaced moveable thin fingers 509a and is arranged to rotate in a clockwise direction.
  • the desired spacing between each un-tipped smoking article is created either by having a moveable thin finger with the corresponding dimension, or by adjusting the speed ratio between the compacting means 210 and the belt 221.
  • Each moveable thin finger 509a is driven by a cam 509b, rather than being fixed to wheel 215, so that movement of each thin finger 509a, relative to wheel 215, is possible.
  • the components are fed into the compacting means 210 at 501 on belt 209. They are then guided onto wheel 211 by guide 511 and carried by wheel 211 in a clockwise direction, as shown by the arrow.
  • Each fixed finger 505a is positioned between components of one un-tipped smoking article and the next un-tipped smoking article, each un-tipped smoking article including a group of components. Since the components are likely to be fairly well spaced out on belt 209, they remain fairly well spaced out on wheel 211.
  • each moveable thick finger 507a takes the place of fixed finger 505a and is positioned between components of one un-tipped smoking article and the next un-tipped smoking article. Because wheel 211 includes seven fixed fingers 505a, whereas wheel 213 includes eight moveable fingers 507a, in order for successful transfer of components from wheel 211 to wheel 213, the two wheels must be rotating at different speeds. This is because the wheels have the same diameter so, for each full rotation of wheel 213, which corresponds to eight smoking article rods, wheel 211 must turn one and one seventh rotations.
  • moveable fingers 507a are driven by cams 507b rather than being fixed to wheel 213. This allows moveable fingers 507a to travel at the same speed as fixed fingers 505a at the interface, by moving relative to wheel 213. Then, once the components are transferred, the cams 507b allow the moveable fingers 507a to return to rotation at the same speed as wheel 213. Since there are eight spaces between moveable fingers on wheel 213, but only seven spaces between fixed fingers on wheel 211, the components within a group of components on wheel 213 are closer together than on wheel 211.
  • each moveable thick finger 507a is positioned between components of one un-tipped smoking article and the next un-tipped smoking article.
  • each moveable thin finger 509a takes the place of moveable thick finger 507a and is positioned between components of one un-tipped smoking article and the next un-tipped smoking article. Because wheel 215 includes eight moveable fingers, just like wheel 213, wheels 213 and 215 are moving at approximately the same speed at the interface between them. However, moveable fingers 509a are thinner than fingers 507a, which results in a smaller separation between components of one un-tipped smoking article and the next un-tipped smoking article.
  • wheel 213 has a slightly different diameter from that of wheel 215.
  • moveable fingers 509a may not require very much movement relative to wheel 215, they are nonetheless driven by cams 509b rather than being fixed to wheel 215. This allows the fingers 509a to move relative to wheel 215 at the interface between wheel 213 and wheel 215, should this be needed to compact the components.
  • the cam mechanism allows for adjustment of the speed of the delivery of the components onto belt 221, in order to compact the components against each other.
  • the components are then carried by wheel 215 in a clockwise direction, as shown by the arrow.
  • the separation between groups of components is the desired space so that, when the components exit the compacting means 210 at 503 on belt 221, they are ready to be overwrapped with paper web in garniture region 217.
  • the blade 223 downstream of the compacting means 210 is arranged to cut the paper web precisely at each gap between un-tipped smoking article components.
  • the size of the gap between each group of components needs to be accurate. This is particularly important with the smoking article of Figure 1 , for example, since the heat sources tend to be hard and difficult to cut.
  • the gap between groups of components may be 1 mm ⁇ 0.5. mm, that is, between 0.5 mm and 1.5 mm, or more preferably between 0.8 mm and 1.2 mm.
  • the components may be adhered to each wheel by suction and transferred between wheels using known vacuum transfer techniques. Other techniques are possible, however.
  • wheels 213 and 215 are shown with eight moveable fingers, so that they can accommodate eight groups of components for eight smoking article rods, but any number of moveable fingers greater than one is possible.
  • Wheel 211 is shown with seven fixed fingers, so that it can accommodate seven groups of components for seven smoking article rods, but any number of fixed fingers is possible. The important feature is that the first wheel 211 holds fewer groups of components than the second wheel 213, so that the components are compacted in the transfer from the first wheel to the second wheel.
  • the properly-spaced components are overwrapped with paper from paper feed 219. This may be performed in a conventional manner. As the components move along the belt, on paper from paper feed 219, the channel steadily becomes more cylindrical, thereby wrapping the paper around the components.
  • each distillation-based smoking article includes a heat-conducting element 121 which may consist of aluminium foil.
  • the aluminium foil is pre-applied to the paper 111, before being fed into paper feed 219 and wrapped over the components.
  • the application of spaced aluminium foil patches to a paper web may be performed by apparatus like that described in pending patent application EP 08250842.5 .
  • One embodiment of such apparatus is shown in Figure 6 .
  • FIG. 6 shows a schematic view of one embodiment of apparatus used to apply spaced heat-conducting elements in the form of aluminium patches to a web of paper.
  • the apparatus 601 comprises backplate 603, aluminium foil input 605 from aluminium foil feed bobbin 607, aluminium foil feed dancing rollers 609 and fixed rollers 611, glue applicator 613, patch cutting drum 615, paper input 617, paper input roller 619, patch transfer drum 621 and paper output 623.
  • the apparatus additionally includes perforation drum 625 and additional glue applicator 627.
  • the thick line is used to indicate the web of aluminium foil
  • the thin line is used to indicate the web of paper
  • the thin line with spaced thick portions is used to indicate the web of paper with applied patches of aluminium foil.
  • Aluminium foil web is fed from feed bobbin 607 to the input 605. Then, the aluminium foil is fed around dancing roller 609 which, as shown by the arrows, can move up and down to affect the tension in the foil web. Then, the aluminium foil web is fed in the direction of the arrows, via fixed rollers 611, to the further dancing rollers 609.
  • the dancing rollers 609 set the speed of the incoming web, according to the required speed at the patch cutting drum 615 and the patch transfer drum 621.
  • the glue applicator 613 applies glue areas or lines or a continuous or an intermittent stream of glue to the web. Then, the glued aluminium foil web proceeds towards the patch cutting drum 615 and the patch transfer drum 621.
  • suction is applied at the entry to patch transfer drum and air is blown outwards at the exit of the patch transfer drum.
  • the glued aluminium foil web passes between the patch cutting drum 615 and the patch transfer drum 621, the web is cut into individual aluminium patches.
  • the individual patches (glue side out) pass in a clockwise direction around the patch transfer drum 621.
  • Paper is fed into paper input roller 619. As the paper comes into contact with the individual aluminium patches on the patch transfer drum 621, the patches are applied to the paper.
  • the glue may then be dried by heaters (not shown).
  • the apparatus allows the aluminium patches to be non evenly spaced on the paper web, if that is required (for example for the component order shown in Figure 4 ). In that case, either electronic driving control or a mechanical cam (not shown) changes the speed of the incoming webs so that patch transfer drum 621 applies the patches to the paper web with two different spacings.
  • the position of the aluminium patches on the paper web is critical, as this affects the position of the heat-conducting elements relative to the heat source and aerosol-generating substrate in the eventual smoking articles. This has a great effect on the heat conducting properties of the smoking article, and hence on the temperature reached at the aerosol-generating substrate and hence on the smoking experience for the user.
  • the aluminium patch may optionally be secured to the heat source, for example via glue from applicator 627, to prevent the heat source from dropping out of the paper overwrap.
  • the perforation drum 625 is used to perforate the paper, so as to form the perforations 129 in the finished smoking article (see Figure 1 ).
  • the perforations may alternatively allow a user to peel off part of the paper overwrap from the heat source. This prevents the paper from burning, when the smoking article is lit.
  • the perforations in Figure 1 are shown extending around the circumference of the smoking article. The perforations may, alternatively extend along the length of the smoking article. Alternatively, the perforations may be added downstream in the tipper.
  • An additional unit may also be supplied to apply printing or other markings to the paper web before input 617 or in the region of glue applicator 627.
  • the paper web exiting the garniture region 217 is then cut by blade 223.
  • the blade 223 cuts the web in the spaces between groups of components.
  • a mouthpiece may be applied to each un-tipped smoking article by tipping paper.
  • the tipping of the un-tipped smoking articles may be carried out by any suitable tipping machine (tipper).
  • the components are fed in a stream along the moving vacuum belt 209.
  • the compacting means 210 the stream of components is compacted into groups of components, each group corresponding to a discrete un-tipped smoking article.
  • the components within a group abut one another and there is a predefined space between a leading group of components and a trailing group of components.
  • the components are wrapped in a web of material.
  • the web of material is cut at each space between groups of components.
