Definitions

  • the present invention relates to a unit for conveying tobacco products.
  • the prior art embraces manufacturing systems for tobacco products that comprise a transfer conveyor unit interposed between a production machine such as a filter maker, for example, and a user machine that might be a filter tip attachment machine, or an assembler of composite filters, that is to say filters consisting in a combination of filter plugs having different filtration properties.
  • a production machine such as a filter maker, for example
  • a user machine that might be a filter tip attachment machine, or an assembler of composite filters, that is to say filters consisting in a combination of filter plugs having different filtration properties.
  • a conveyor unit of the aforementioned type would serve in this instance to transfer filter sticks or plugs, and will feed the sticks or plugs to the user machine either directly or employing temporary storage containers.
  • the two tracks will be connected by two conveyor units to respective filter tip attachment machines, or possibly to two infeed points of a single machine assembling composite filters.
  • the object of the present invention is to provide a unit for conveying tobacco products that will be extremely compact, versatile, and effective in the same measure when connecting either a one-track or a twin-track maker to either a single user machine or a plurality of user machines.
  • numeral 1 denotes a unit for conveying tobacco products, in its entirety, interposed between a production machine 2 turning out filter sticks or plugs, shown schematically as a block, and receiving means denoted 3 and 4.
  • the production machine 2 is a twin-track filter maker, that is, a type having a garniture tongue 5 with two channels 6 and 7 extending side by side, along which respective continuous filter rods 8 and 9 are formed, and a rotary cutter 10 by which the two rods are divided respectively into discrete lengths consisting in filter sticks 11 and 12, for example.
  • the conveyor unit 1 presents a structure disposed symmetrically on either side of a vertical plane 13 parallel with and equidistant from the channels 6 and 7, and comprises rotary conveyor means placed to take up and feed the filter sticks 11 and 12, embodied as a pair of rollers 14 and 15 rotatable anticlockwise and clockwise, respectively, about corresponding horizontal axes 16 and 17 parallel to the vertical plane 13.
  • Each of the two rollers 14 and 15 is furnished peripherally with aspirating flutes 18 equispaced one from the next at a predetermined pitch P, into which respective sticks 11 and 12 are directed singly and in succession from the runout end of the tongue 5.
  • the unit 1 comprises further rotary conveyors consisting in a second pair of rollers 19 and 20, identical one with another, mounted on shafts 21 and 22 of which the axes 23 and 24 extend parallel to the axes 16 and 17 of the feed rollers 14 and 15, and rotatable thus clockwise and anticlockwise, respectively, at the same tangential speed as the aforementioned rollers 14 and 15.
  • the two rollers 19 and 20, furnished peripherally with flutes 25 equispaced one from the next at a pitch p equivalent to half the pitch P of the flutes 18 aforementioned, are located respectively between the feed rollers 14 and 15 on the one hand, with which a substantially tangential interface is established at infeed positions denoted 26 and 27, and on the other, positions 28 and 29 at which the sticks 11 and 12 are released to the aforementioned receiving means 3 and 4.
  • the two second rollers 19 and 20 also rotate substantially tangential one to another at a point denoted 30 and are positioned angularly on the respective shafts 21 and 22 in such a way that the single flutes 25 of the one roller 19 will align in succession with the single flutes 25 of the other roller 20 at the point of tangency 30.
  • each of the two rollers 19 and 20 comprises two rotary members carried in rotation by the relative shaft 21 and 22, and more exactly an outer sleeve 31 affording the flutes 25, and an inner sleeve 32 constituting distribution means.
  • Each shaft 21 and 22 also carries two fixed cylindrical elements 33 and 34 concentric one with another.
  • the innermost cylindrical element 33 communicates by way of a duct 35 with a source of negative pressure (not illustrated) and is furnished with a through radial slot 36 directed toward the relative infeed position 26 and 27.
  • the outer cylindrical element 34 is fashioned with a radial slot 37 placed to coincide with the slot 36 of the inner element, and functions as the inner wall of a chamber 38 that extends angularly from a point coinciding with the infeed position 26 or 27, through an arc of between 180° and 270°, and is delimited externally by the inner cylindrical surface of the distribution sleeve 32.
  • Numeral 39 denotes valve means consisting in a vane or slide 40 riding against the internal cylindrical surface of the distribution sleeve 32 and positionable thus within the chamber 38.
  • the chamber 38 is divided into a first portion or sector 41, compassed between the infeed position 26 or 27 and the slide 40 and connected directly to the aforementioned negative pressure source by way of the slots 36 and 37, and a second portion or sector 42 located downstream of the slide 40, relative to the direction of rotation of the roller 19 or 20, which remains at atmospheric pressure as will become clear in due course.
  • each of the peripheral flutes 25 is furnished with two holes 43 located at points near to its two ends, set apart one from another at a distance denoted d, whilst the inner or distribution sleeve 32 (figure 5) presents a first set of holes 44 ordered in pairs axially aligned and set apart at the aforementioned distance d, and a second set of holes 45 ordered in pairs set apart likewise one from another by the same distance d, and offset axially by a given distance from the holes 44 of the first set.
  • the paired holes 44 of the first set are arranged on the inner sleeve 32 equispaced angularly at a selected pitch P, whilst the paired holes 45 of the second set are equispaced at a pitch p equivalent to half the aforementioned pitch P.
  • the inner sleeve 32 is mounted to the relative shaft 21 or 22 with freedom of axial sliding movement, induced by actuator means of conventional type (not illustrated), and positionable thus in such a manner as to bring about a first coupling between the two holes 43 in every second flute 25 of the outer sleeve 31 and each pair of holes 44 of the first set, spaced at pitch P (see figure 4a), or alternatively, a second coupling between the two holes 43 in each and every flute 25 of the outer sleeve 31 and each pair of holes 45 of the second set, spaced at pitch p (see figure 4b).
  • the valve means 39 combine with the distribution means 32 to create a device by which the flutes 25 are connected selectively to the source of negative pressure.
  • the slides 40 of the two rollers 19 and 20 are positioned at the respective release positions 28 and 29, and the distribution sleeves 32 of the rollers 19 and 20 are positioned as in figure 4a, in such a manner as to bring about the first coupling, that is to say with every second flute 25 connected to the source of negative pressure.
  • the inner sleeves 32 of the two rollers 19 and 20 are positioned angularly relative one to another on the respective shafts 21 and 22 in such a way that when passing through the point of tangency 30, under normal operating conditions, each aspirating flute 25 of the one roller 19 or 20 will align with a non-aspirating flute 25 of the other roller 20 or 19.
  • the filter sticks 11 and 12 taken up onto the rollers 19 and 20 at the infeed positions 26 and 27 are transferred beyond the point of tangency 30, with no mutual interference occurring between the two flutes 25 meeting at the selfsame point, and toward the release positions 28 and 29, where the positioning of the slides 40, each delimiting the aspirating first sector 41 of the relative chamber 38, is such as to shut off the connection between the flutes 25 and the source of negative pressure.
  • the filter sticks 11 and 12 are transferred respectively to the receiving means 3 and 4, each of which comprises an inclined chute 46 emptying onto a relative horizontal conveyor 47 along which the filter sticks will accumulate en masse.
  • Each conveyor 47 is looped at the ends around respective timing pulleys 48 of which one only, turning on a relative shaft 49, is indicated in figure 1.
  • each chute 46 is furnished at the infeed end with a pivotable guide 50 hinged by a free top end to an inclined wall 51 forming part of the chute 46 and hinged in its turn about an axis parallel to the axis of the pulley shaft 49.
  • the operating configuration shown in figure 2 differs from that of figure 1 in that the inner sleeve 32 of one roller 19 is in the aforementioned second coupling position, whereby the two holes 43 of every flute 25 are matched with each pair of holes 45 of the second set, at the shorter pitch p (see figure 4b), and the slide 40 is located at the release position 28.
  • the inner sleeve 32 occupies the first coupling position in which the two holes 43 of every second flute 25 are matched with each pair of holes 44 of the first set, at the longer pitch P (see figure 4a), and the slide 40 is located at the point of tangency 30.
  • the aspirating first sector 41 of the chamber 38 inside this roller 20 extends from the relative infeed position 27 to the point of tangency 30, where the respective sticks 12 are taken up by the vacant flutes 25 of the other roller 19, alternated with the flutes 25 occupied by the sticks denoted 11.
  • the sticks 11 and 12 of both streams will follow the same path toward the release position 28 associated with the receiving means denoted 3.
  • the conveyor unit 1 thus described will be seen to be extremely versatile, given that different operating conditions can be accommodated simply by altering the angular position of the slide 40 within the chamber 38, and the axial position of the inner sleeve 32.
  • the production machine 2 which in the embodiment described by way of example is a twin-track filter maker, might equally well be replaced by two one-track machines turning out sticks 11 and 12 having identical or dissimilar properties, or even a single machine from which sticks 11 or 12 are taken up by just one roller 14 or 15.
  • the sticks 11 or 12 can be directed by the second pair of rollers 19 and 20 toward both of the receiving means 3 or 4, or to just one of these same receiving means.
