Definitions

  • the present invention relates to a device for feeding filter rods in a filter tip attachment machine .
  • filter rod is used to describe a stick of filter material, prepared to a predetermined length and subjected to a cross-cutting step from which two or three filter plugs are obtained, each twice the length of a single tip destined ultimately to form part of one filter cigarette. More particularly, the present invention relates to a roller by which single filter rods are taken up from the bottom of a feed hopper.
  • the outer cylindrical surface of the take-up roller coincides with the bottom of the hopper and is furnished with a plurality of aspirating flutes positioned to receive the single filter rods, in such a way that when the roller is set in rotation, the rods can be transferred away from the hopper and directed through one or more cutting stations where they are divided into plugs, thence toward a station where they are transferred to a further roller.
  • the single flutes function primarily as elements by means of which to retain the single filter rods, but also as steadying elements with which one or more disc cutters, rotating about respective axes parallel to the axis of rotation of the take-up roller, are able to interact during the cutting step.
  • the cutter or cutters operating at one or more relative stations will pass through respective radial gaps afforded by the take-up roller, extending transversely to each flute, in such a way as to slice likewise transversely through the filter rod.
  • the intention is to obtain two plugs from a single filter rod, there will be just one disc cutter operating on the path followed by the flutes between the take-up area and the point of transfer to the next roller, and the flutes themselves will present a single gap, positioned intermediately to coincide with the area where the cutting edge of the disc passes through the rod.
  • the intention is to obtain three plugs of equal length from a single filter rod, there will be two disc cutters operating along the path followed by the flutes between the take-up area and the point of transfer to the next roller, distanced one from the other along a direction parallel with the axis of the take-up roller. Accordingly, the flutes will present two mutually parallel gaps placed to coincide with the areas where the cutting edges of the discs pass through the rod.
  • the object of the present invention is to set forth a device for feeding filter rods in a filter tip attachment machine, such as will allow of overcoming the drawbacks mentioned above.
  • -figure 1 shows a device for feeding filter rods in a filter tip attachment machine, viewed schematically from the front and with certain parts omitted;
  • -figures 2 and 3 show a take-up roller of the feed device in figure 1, viewed schematically from the side in an axial section, and illustrated in two different operating configurations;
  • -figures 4 and 5 show the take-up roller of the feed device in figure 1, viewed schematically from the side in an axial section, and illustrated in two further different operating configurations;
  • -figure 6 shows the take-up roller of figures 1 to 5 , viewed schematically from the front and with certain parts omitted.
  • the feed device 1 denotes a device, in its entirety, for feeding filter rods 2 in a filter tip attachment machine (not illustrated) .
  • the feed device 1 comprises a hopper 3 filled with a mass 4 of filter rods 2, of which the outlet is enclosed by a take-up roller 5 positioned to receive the rods 2.
  • the roller 5 rotates anticlockwise as seen in figure 1, about an axis 6 normal to the viewing plane of this same drawing, and is furnished peripherally with a plurality of longitudinal flutes 7 extending parallel to the axis 6 of rotation, each serving to take up and retain a single filter rod 2 by suction.
  • the device 1 further comprises a barrier roller 8 located at the point where the take-up roller 5 rotates beyond the bottom of the hopper 3 and turning in the same direction as the take-up roller 5 about an axis parallel to the axis 6 aforementioned, of which the function is to ensure that any rods 2 not seated properly within the flutes 7 will be prevented from leaving the hopper 3. Also illustrated in figure 1 are cutting means denoted 9 in their entirety, placed downstream of the barrier roller 8 along a predetermined feed path P followed by the rods 2 seated in the flutes 7, such as will cut through the rods 2 transversely and divide them into plugs 10 of uniform length.
  • the cutting means 9 might take the form of a single disc cutter 11, where the requirement is to divide each rod 2 into two plugs 10, or alternatively a pair of disc cutters 11, where the requirement is to divide each rod 2 into three plugs 10.
  • the cutters 11 will be arranged in sequence along the feed path P, as discernible from the phantom lines of figure 1, and offset axially one from another.
  • 12 denotes a station located downstream of the cutting means 9, along the feed path P, at which the filter plugs 10 are transferred from the take-up roller 5 to a further roller 13 of which the function is to stagger the plugs 10 axially while directing them toward a successive processing station (not illustrated) of the filter tip attachment machine.
  • the take-up roller 5 comprises an inner cylindrical body 14 coupled to conventional drive means (not illustrated) and, mounted symmetrically to the body 14 on either side of a median plane transverse to the axis 6 of the roller 5, two first annular elements 15 and 16 constituting first modules 17, also two second annular elements 18 and 19 located in contact respectively with the outer radial faces 15a and 16a of the first elements 15 and 16 and constituting second modules 20.
  • the roller 5 comprises two third annular elements 21 and 22 fitted respectively over the free outer ends of the two second annular elements 18 and 19 and constituting third modules 23.
  • each one of the first annular elements 15 and 16, the second annular elements 18 and 19 and the third annular elements 21 and 22 presents a plurality of grooves equispaced angularly about the respective cylindrical outer surface. Accordingly, each one of the aforementioned flutes 7 presented by the take-up roller 5 will include a central portion composed of two grooves 24 and 25 afforded respectively by the two first annular elements 15, and intermediate portions consisting of two grooves 26 and 27 afforded respectively by the two second annular elements 18 and 19. Similarly, the single flute 7 includes end portions consisting of two grooves 28 and 29 afforded respectively by the third annular elements 21 and 22.
  • first and second modules 17 and 20 are associated with the cylindrical body 14 of the take-up roller 5 by way of an interfacing sleeve 30, occupying a fixed angular position while remaining capable of axial movement; similarly, the third modules 23 are fitted over the second modules 20 occupying a fixed angular position and capable of axial movement.
  • the second annular elements 18 and 19 are held in close contact with the respective walls 15a and 16a of the first annular elements 15 and 16 by means of respective axial tension means 31.
  • the tension means 31 in question consist in a plurality of springs 32 and 33 distributed angularly about the periphery of the roller 5, of which the springs denoted 32 relative to one second annular element 18 are interposed between the free end of this same element and respective housings 34 afforded by the rim of a circular flange 35, disposed concentrically with the roller 5 and secured to the end of the sleeve 30 nearer the aforementioned drive means of the roller.
  • the springs denoted 33, relative to the other second annular element 19, are interposed between the free end of this same element and respective housings 36 afforded by an annular edge 37 of the sleeve 30 at the projecting end of the take-up roller 5.
  • first motion-inducing means 41 comprise a plurality of first rods 42 and 43 extending parallel to the aforementioned axis 6, intercalated and equispaced angularly around the periphery of the take-up roller 5, and coupled by way of respective lead screw assemblies respectively with each of the first annular elements 15 and 16.
  • the threads of the rods denoted 42 and the threads of the rods denoted 43 are of opposite hand.
  • the rods 42 and 43 present respective heads 44 occupying a common plane transverse to the roller 5 and incorporating teeth in mesh with a first common transmission component 45 consisting in a first ring gear 46 associated concentrically with the roller 5 and mounted rotatably within an annular housing 47 afforded by the end of the sleeve 30 at the projecting end of the roller 5.
  • the axial adjustment means 40 will comprise second motion-inducing means 48 associated with the third modules 23.
  • the second motion-inducing means 48 comprise a plurality of second rods 49 and 50 extending parallel to the axis 6 of the take-up roller 5, intercalated one with another and with the first rods 42 and 43, equispaced angularly around the periphery, and coupled by way of respective lead screw assemblies respectively to each of the third annular elements 21 and 22.
  • the threads of the rods denoted 49 and the threads of the rods denoted 50 are of opposite hand.
  • the rods 49 and 50 present respective heads 51 occupying a common plane transverse to the roller 5 and parallel to the plane occupied by the heads 44 of the first rods.
