Definitions

  • the present invention relates to an automatic cigarette filter manufacturing machine provided with a feed unit for feeding thread.
  • Cigarette filters have been proposed, in which at least one piece of thread is inserted centrally to embellish the filter (i.e. using a thread of a different colour from the conventional white filtering material) and/or to aromatize the filter (using a thread impregnated with volatile aromatic substances).
  • automatic cigarette filter manufacturing machines are equipped with a thread feed unit, on which the thread is unwound off a spool; and an insertion unit, which receives the continuous thread from the feed unit, and inserts it into a strip of filtering material at a pneumatic conveyor assembly, which compacts the strip of filtering material into a rope.
  • Patent Application WO2008016839A1 describes a feed unit, which feeds a thread to an insertion unit connected to a pneumatic conveyor assembly of an automatic cigarette filter manufacturing machine.
  • the feed unit comprises a vertical unwinding pin supporting a spool wound with a reel of thread, which is gradually unwound; and a number of fixed thread guides, which guide the thread from the periphery of the reel to the insertion unit connected to the pneumatic conveyor assembly.
  • an automatic cigarette filter manufacturing machine provided with a feed unit for feeding thread, and as claimed in the accompanying Claims.
  • Number 1 in Figure 1 indicates as a whole a dual automatic manufacturing machine for producing cigarette filters.
  • Machine 1 comprises two forming beams 2a, 2b for forming respective continuous filter rods 3a, 3b; and a filtering material feed line 4a, 4b for each forming beam 2a, 2b.
  • Feed lines 4a, 4b receive the filtering material from a conveyor line 5, which forms part of machine 1 and extends between an input station 6 of feed lines 4a, 4b and a store 7 containing two bales 8a, 8b of filtering material.
  • Respective strands 9a, 9b are unwound from bales 8a, 8b and pulled along conveyor line 5 by a traction roller assembly 10a at input station 6.
  • Conveyor line 5 comprises a guide device 11 located over bales 8a, 8b to guide strands 9a, 9b; and an expanding device 12 located at input station 6, directly upstream from traction roller assembly 10a, to expand strands 9a, 9b crosswise with jets of compressed air and form respective flat-section strips 13a, 13b, which are then fed to traction roller assembly 10a.
  • strips 13a, 13b Downstream from traction roller assembly 10a, strips 13a, 13b are fed, along respective feed lines 4a, 4b and in a substantially horizontal direction 14, through a pressing unit 15 comprising two traction roller assemblies 10b, 10c similar to assembly 10a.
  • strips 13a, 13b are fed, along respective feed lines 4a, 4b in direction 14, through an inflating device 16, which blows air into strips 13a, 13b; and then through a processing unit 17, where a chemical substance, in particular triacetin, is added to strips 13a, 13b to impart aroma and plasticity to the filtering material.
  • strips 13a, 13b are fed, along respective feed lines 4a, 4b in direction 14, through a traction roller assembly 10d similar to assemblies 10a and 10b, 10c, and which defines an output portion of feed lines 4a, 4b.
  • Feed lines 4a, 4b are connected to forming beams 2a, 2b by a pneumatic conveyor assembly 18 located directly downstream from traction roller assembly 10d.
  • Pneumatic conveyor assembly 18 receives strips 13a, 13b from feed lines 4a, 4b, and feeds strips 13a, 13b to forming beams 2a, 2b.
  • strips 13a, 13b of filtering material, already partly gathered by assembly 18, are further gathered and compacted to form respective cylindrical ropes of filtering material. These are fed onto respective paper strips 19a, 19b, gummed beforehand at a gumming station 20, and are then wrapped crosswise in strips 19a, 19b to form two continuous filter rods 3a, 3b.
  • a control station 21 checks the density of filter rods 3a, 3b, and a cutting head 22 cuts rods 3a, 3b transversely into respective successions of filter portions (not shown).
  • automatic manufacturing machine 1 comprises a feed unit 23 for supplying pneumatic conveyor assembly 18 with two threads 24a, 24b, each of which is inserted into the centre of a corresponding filtering material rope when compacting respective strip 13a, 13b.
  • Threads 24a, 24b may serve to embellish continuous filter rods 3a, 3b (i.e. using threads of a different colour from the conventional white filtering material) and/or to aromatize the filter rods (using threads 24a, 24b impregnated with volatile aromatic substances).
  • pneumatic conveyor assembly 18 comprises an insertion unit 25, which receives threads 24a, 24b from feed unit 23, and inserts threads 24a, 24b into respective strips 13a, 13b of filtering material.
  • feed unit 23 comprises a vertical frame 26, which is mounted on brake wheels 27 (i.e. each fitted with a releasable brake to prevent it from rotating), and supports twin vertical supporting tables 28a, 28b (only one shown in Figure 2 ) located on opposite sides of frame 26.
  • Each supporting table 28a, 28b is circular, and is fitted to frame 26 to rotate about a horizontal centre axis of rotation 29 (i.e. perpendicular to frame 26). Both supporting tables 28a, 28b share the same centre axis of rotation 29, and are parallel and coaxial.
  • Each supporting table 28a, 28b is fitted with three unwinding pins 30 (shown in Figures 4 and 6 ), each of which supports a spool 31, wound with a reel 32 of thread 24a, 24b, as reel 32 is unwound.
  • the three unwinding pins 30 are arranged side by side along the periphery of respective supporting table 28a, 28b, and are equally spaced about centre axis of rotation 29.
  • each supporting table 28a, 28b can accommodate up to three reels 32 at a time: obviously, only one reel 32 is unwound at a time, the other two reels 32 being standbys, i.e. which are unwound (one after the other) when the unwinding reel 32 runs out.
  • the twin supporting tables 28a, 28b provide for simultaneously unwinding both threads 24a, 24b, which are fed together to dual automatic manufacturing machine 1: thread 24a for filter rod 3a is unwound off a reel 32 on an unwinding pin 30 on supporting table 28a, while thread 24b for filter rod 3b is unwound off a reel 32 on an unwinding pin 30 on supporting table 28b.
  • each unwinding pin 30 is parallel to supporting table 28a, 28b (i.e. crosswise to centre axis of rotation 29) and is connected to supporting table 28a, 28b by a connecting arm 33 (shown in Figures 3 and 6 ) with which it forms an L-shaped structure.
  • each connecting arm 33 projects perpendicularly from supporting table 28a, 28b (i.e. axially with respect to supporting table 28a, 28b and therefore parallel to centre axis of rotation 29), and the end of connecting arm 33 opposite supporting table 28a, 28b is fitted with unwinding pin 30, which is perpendicular to connecting arm 33 (and therefore parallel to supporting table 28a, 28b).
  • each unwinding pin 30 is fitted idly to connecting arm 33 to rotate freely about its longitudinal axis.
  • each unwinding pin 30 is fixed to connecting arm 33.
  • frame 26 of feed unit 23 is fitted with a number of guide members 34 for guiding thread 24a, 24b, and which are located in a fixed position alongside supporting table 28a, 28b to guide the unwinding thread 24a, 24b from supporting table 28a, 28b (i.e. from corresponding reel 32) to insertion unit 25 integrated in pneumatic conveyor assembly 18.
  • frame 26 of feed unit 23 has a top arm 35 extending vertically upwards from the top of frame 26 and supporting a number of guide members 34.
  • each supporting table 28a, 28b is mounted to rotate about centre axis of rotation 29, to move each unwinding pin 30 cyclically into two unwinding stations 36, 37, where unwinding pin 30 (and therefore reel 32 fitted to unwinding pin 30) is located close to guide members 34; and into a standby station 38, where unwinding pin 30 (and therefore reel 32 fitted to unwinding pin 30) is located away from guide members 34. More specifically, unwinding stations 36 and 37 are located at the top (to the right and left of guide members 34), and standby station 38 is located at the bottom.
  • supporting table 28a rotates anticlockwise, so, for each 120° rotation of supporting table 28a, the unwinding pin 30 at standby station 38 moves into the 'right' unwinding station 36; the unwinding pin 30 at the 'right' unwinding station 36 moves into the 'left' unwinding station 37; and the unwinding pin 30 at the 'left' unwinding station 37 moves into standby station 38.
  • each supporting table 28a, 28b about centre axis of rotation 29 is controlled by an electric motor 39, which is fitted to frame 26, alongside supporting table 28a, 28b, and drives supporting table 28a, 28b via an endless belt 40 wound about the periphery of supporting table 28a, 28b. More specifically, cascade gearing connects a drive shaft of electric motor 39 angularly integral with a drive pulley 41, about which belt 40 is wound.
  • each unwinding pin 30 is fitted to supporting table 28a, 28b to rotate, with respect to supporting table 28a, 28b, about a peripheral axis of rotation 42 parallel to centre axis of rotation 29 (i.e. perpendicular to supporting table 28a, 28b and crosswise to unwinding pin 30).
  • each supporting table 28a, 28b is connected to an actuating device 43, which adjusts the angular position of each unwinding pin 30 with respect to supporting table 28a, 28b as a function of the angular position of supporting table 28a, 28b about centre axis of rotation 29.
  • each actuating device 43 adjusts the angular position of each unwinding pin 30 with respect to supporting table 28a, 28b so as to set unwinding pin 30 to the best position with respect to guide members 34 guiding thread 24a, 24b: as shown in Figure 4 , both reel 32 at the 'right' unwinding station 36, and reel 32 at the 'left' unwinding station 37 are oppositely oriented so that both 'face' guide members 34 guiding thread 24a.
  • each actuating device 43 comprises at least two cams 44 ( Figure 5 ) located in fixed positions about centre axis of rotation 29; and, for each unwinding pin 30, two corresponding cam followers 45 ( Figures 5 and 6 ) which engage cams 44 and are connected mechanically to unwinding pin 30.
  • connecting arm 33 of each unwinding pin 30 is fitted in rotary manner to supporting table 28a, 28b, and has an outer end connected rigidly to unwinding pin 30, and an inner end (opposite the outer end) integral with a vertex of a triangular frame 46; and the two cam followers 45 are fixed to triangular frame 46 at the other two vertices not engaged by the inner end of connecting arm 33.
  • the two cam followers 45 thus control the angular position of triangular frame 46 about peripheral axis of rotation 42, and therefore also the angular position of unwinding pin 30 about peripheral axis of rotation 42.
  • each supporting table 28a, 28b comprises three splicing devices 47 fixed to supporting table 28a, 28b and each located between two unwinding pins 30.
  • Each splicing device 47 is used to splice a trailing end of thread 24a, 24b on a reel 32 fitted to an unwinding pin 30 on one side of splicing device 47, to the leading end of thread 24a, 24b on a reel 32 fitted to an unwinding pin 30 on the other side of splicing device 47. Threads 24a or 24b of the two reels 32 are thus joined continuously, so, once one reel 32 runs out, unwinding of the other reel 32 commences automatically and seamlessly.
  • Each splicing device 47 is normally activated by an operator, who first inserts the two ends for splicing inside respective seats on splicing device 47, and then turns on splicing device 47, which at this point splices the two ends automatically.
  • each splicing device 47 untwists the ends of the two threads 24a or 24b for splicing, superimposes the untwisted ends, and then connects the two ends mechanically using jets of water and air, which twist the two ends together.
  • each supporting table 28a, 28b is fitted with other than three unwinding pins 30, e.g. two or four unwinding pins 30 equally spaced about centre axis of rotation 29.
  • automatic manufacturing machine 1 is a one-line machine, and so only needs to receive one thread 24.
  • This embodiment may therefore employ either feed unit 23 with two supporting tables 28a and 28b (obviously, only one supporting table 28a or 28b is used, and the other 28b or 28a is left idle) or a feed unit 23 with one supporting table 28.
  • feed unit 23 described above will now be described with reference to supporting table 28a, which feeds thread 24a to insertion unit 25 integrated in pneumatic conveyor assembly 18 of automatic manufacturing machine 1 (supporting table 28b operates in exactly the same way as supporting table 28a).
  • an operator loads three spools 31, each wound with a full reel 32, onto the three unwinding pins 30 on supporting table 28a.
  • the operator then takes the leading end of thread 24a on the reel 32 in the 'left' unwinding station 37, and threads it manually through corresponding guide members 34 to insertion unit 25 integrated in pneumatic conveyor assembly 18.
  • the operator (using corresponding splicing device 47) then splices the trailing end of thread 24a on the reel 32 in the 'left' unwinding station 37 to the leading end of thread 24a on the reel 32 in the 'right' unwinding station 36, and (using the corresponding splicing device 47) splices the trailing end of thread 24a on the reel 32 in the 'right' unwinding station 36 to the leading end of thread 24a on the reel 32 in standby station 38.
  • automatic manufacturing machine 1 can be started, and begins using thread 24a unwound off reel 32 in the 'left' unwinding station 37; when reel 32 in the 'left' unwinding station 37 runs out, reel 32 in the 'right' unwinding station 36 is unwound automatically, by virtue of the trailing end of thread 24a on reel 32 in the 'left' unwinding station 37 being spliced to the leading end of thread 24a on reel 32 in the 'right' unwinding station 36.
  • electric motor 39 rotates supporting table 28a 120° anticlockwise about axis of rotation 29 to move the unwinding reel 32 into the 'left' unwinding station 37, to move the full reel 32 into the 'right' unwinding station 36, and to move the run-out spool 31 into standby station 38.
  • the operator may replace the run-out spool 31 in standby station 38 with a new spool 31 wound with a full reel 32, and so (using the corresponding splicing device 47) splices the trailing end of thread 24a on reel 32 in the 'right' unwinding station 36 to the leading end of thread 24a on reel 32 in standby station 38.
  • the operator may wait for two spools 31 to run out, before replacing them with respective spools 31 with full reels 32.
  • Feed unit 23 described has numerous advantages.
  • feed unit 23 provides for supplying insertion unit 25 of automatic manufacturing machine 1 with three reels 32 of thread 24a or 24b, before any operator assistance is needed.
  • supply of thread 24a, 24b to insertion unit 25 of automatic manufacturing machine 1 need never be interrupted, in that, on each supporting table 28a, 28b, as thread 24a, 24b is being unwound off one reel 32 on one unwinding pin 30, the other two run-out reels 32 on the other two unwinding pins 30 can be replaced with full reels 32.
  • Feed unit 23 described provides for safely unwinding thread 24a, 24b off reel 32, by virtue of the unwinding reel 32 always being set to the best position, with respect to guide members 34, to avoid overstressing thread 24a, 24b, thus preventing thread 24a, 24b from breaking as it is unwound (particularly at the splices between the trailing end of one reel 32 and the leading end of the following reel 32, which are always weaker points). Breakage of thread 24a, 24b is a serious occurrence, which can only be remedied with the assistance of the operator, and which calls for immediate shutdown of automatic manufacturing machine 1, thus resulting in serious output losses: even only one minute's downtime means the loss of several thousand filter portions.
  • Feed unit 23 described can be installed quickly and easily on any automatic manufacturing machine 1, and even only when required to produce filters with thread 24. This is an important characteristic, in that it allows feed unit 23 to be shared between various automatic manufacturing machines, thus reducing cost.
  • feed unit 23 described is cheap and easy to implement.
  • Feed unit 23 described is installed on an automatic cigarette filter manufacturing machine 1, but may also be used to advantage to feed any type of thread to any type of automatic manufacturing machine employing thread.
