Definitions

  • This invention relates to feeding devices for cigarettes or other rod-like articles, primarily for use in apparatus for filling boxes, trays or the like with such articles.
  • While devices embodying the invention may be employed to handle a wide variety of rod-like articles, particular problems arise in the handling of cigarettes because they are of relatively low density, their paper wrappers are of low mechanical strength, and their quality and value may readily be reduced by rough handling which tends to cause loss of tobacco from their open ends. Cigarette-making machines, however, now operate at high speeds, e.g., 2,000 cigarettes per minute, so that high-speed handling of the cigarettes produced is necessary.
  • a feeding device for cigarettes or other rod-like articles comprising a plurality of parallel shafts having their axes in a common, substantially horizontal plane, each of said shafts being of polygonal cross-section and being separated from each neighbouring shaft by a space of sufiicient width to allow articles to be fed to pass therebetween, driving means connected to all said shafts and adapted to produce rotation thereof, and a plurality of movable blocking members, at least one for each of said spaces, said blocking members being connected to common actuating means operable to move said blocking members between blocking positions in which they block said spaces against passage of articles and withdrawn positions below said shafts.
  • the article feed can conveniently be controlled by pneumatic means operable to stop individual cigarettes or other articles so that the stopped articles block the passage of following articles.
  • a feeding device for cigarettes or other rodlike articles comprising a plurality of horizontal shafts having their axes in a common, substantially horizontal plane, each of said shafts being of polygonal cross-section and being separated from each neighbouring shaft by a space of suflicient width to allow articles to be fed to pass therebetween, driving means connected to all said shafts and adapted to produce rotation thereof, guide members arranged to define passages constituting prolongations of the spaces between neighbouring shafts, said guide members each including at least one port facing one of said passages, and means for applying suction to said ports so that atmospheric pressure urges and holds articles against said ports to block said passages.
  • the guide members may be either above or below the shafts it is preferred to arrange the guide members below the shafts in such manner that at least part of each of the passages is inclined at an angle to the vertical, with the ports in position substantially vertically below the spaces between neighbouring shafts.
  • Each article which falls through one of said spaces then comes into contact with one of the guide members, and in the absence of suction at the ports the article is momentarily stationary across the port or ports of that guide member as it changes direction due to the inclination of the passage; if however suction is then being applied to the ports, when the article reaches said position across the port or ports, atmospheric pressure is effected to retain the article in that position so long as the application of suction is maintained.
  • the guide members may be provided with internal ducts connected to the ports and communicating via a common control valve with a single suction pump; as the ports of the various guide members will not all (except by chance) be covered simultaneously by articles being fed when suction is applied by opening said valve, the dimensions of the ports and the rating of the suction pump must be such that even when all the ports are uncovered the pressure in said ducts is sufficiently low for the first article to cover a port after application of suction to be held.
  • FIGURE 1 is a fragmentary section of a cigarette feeding device embodying the invention, with cigarettes passing through it;
  • FIGURE 2 is a view similar to FIGURE 1, showing conditions existing when feed is stopped;
  • FIGURE 3 is a plan view, with parts in section, of the device of FIGURES 1 and 2;
  • FIGURES 4 and 5 are sections in the planes indicated by lines lV-IV and V-V respectively (FIGURE 3), background detail being omitted;
  • FIGURE 6 is a fragmentary view showing a modification.
  • the device shown has a number of parallel rollers 1, each of hexagonal section, which in operation all rotate clockwise as seen in these figures.
  • the spacing between adjacent rollers 1 is sufiicient to permit cigarettes 2 from a bulk supply 3 above said rollers to fall therebetween.
  • each roller 1 a fixed guide member 4 consisting of a main body 4a and a deflector portion 4b.
  • the body 4a fits closely below the associated roller 1, having a recessed top surface accommodating said roller, and has vertical side faces defining (with corresponding faces of adjacent bodies 4a) passageways 5 forming downward prolongations of the spaces between adjoining rollers 1
  • Each deflector portion 4b is secured to the undersurface of its associated body 4a, in an offset position (to the right as seen in FIGURES 1-3), and the side faces of the portions 417 are inclined to the vertical, so that each deflector portion projects laterally by a distance equal to the width of the passage between its associated body 4a and the next body 4a to the right.
  • each body 4a is charnfered off (as indicated at 40) to provide a continuation of the left side face of the associated portion 45.
  • the side faces of adjoining deflector portions 4b (together with chamfered corners 4c) thus define further portions 511 of the aforesaid passageways 5, these further portions being however inclined to the vertical.
  • the bodies 4a of guide members 4 each have pairs of upwardly-projecting tongues 6 received in circumferential channels 7 of the associated roller 1; the tongues 6 assist in preventing the trapping of cigarettes, with consequent damage, between the rollers 1 and the top surfaces of associated bodies 4a.
  • each deflector portion 4b has a central port 3 communicating via a bore 9 in said portion 4b with a port 10 and longitudinal bore 11 in the associated body 4a.
  • the bore 11 extends to one end of the body 4a Where it communicates with the interior of a manifold 12 common to all the bodies 4a, said manifold 12 and bodies 4a being so mounted that atmospheric air has no access to the interior of the manifold 12 except via ports 8, bores 9, ports 10 and bores 11 just described.
  • the manifold 12 contains a control valve 13 adjacent its left-hand end (FIGURE 3) and at said left-hand end is connected by a pipe 14 to a suction pump 15.
  • the control valve 13, seen more clearly in FIGURE 5, comprises a plate 16 secured to a shaft 17 and a sprung flap 18 normally covering and sealing an aperture 19 in the top wall of the manifold 12.
  • the suction pump When the plate 16 lies in a horizontal plane, being its normal or open position (as shown in full lines in FIGURE 5), the suction pump is effective to apply suction to the ports 8 via the manifold and communicating bores described above; the shaft 17 can however be rotated to raise the right-hand end (as seen in FIGURES 3 and 5) of plate 16 to a closed or bypass position (shown in broken line in FIGURE 5) in which said end engages and lifts the flap 18, so that air can enter via the aperture 19 and thereupon as will be apparent no suction is applied to ports 8.
  • FIGURE 3 also shows one possible arrange ment for valve operation, when the present invention is employed in a machine as disclosed in our aforesaid copending application.
  • the shaft 17 carries, externally of the manifold 12, an arm 20 engagea-ble by a pin 21 which is mounted eccentrically in a disc 22 carried on a further shaft 23 and drivingly connected to said shaft 23 by a clutch 24.
  • clutch 24 is engaged, valve 13 is operable by appropriate angular movements of the shaft 23.
  • each descending cigarette necessarily strikes against the righthand or upper face of one of the deflector portions 412 at such a position as substantially to cover the port 8 therein.
  • valve 13 While feeding is proceeding as in FIGURE 1, no suction is applied to ports 8, valve 13 having its plate 16 in the closed or bypass condition previously described. To stop feeding, valve 13 is operated to bring it to its normal or open position and as explained above suction is then applied to ports 8. When a cigarette next strikes the righthand face of any the deflector portions 412, that cigarette is held stationary by a force pressing it against the said deflector portions, due to the fact that through port 8 a cigarette against said surface.
  • valve 13 As soon as valve 13 is moved back to its closed or bypass position, suction ceases to be applied to ports 8, and the force pressing each cigarette lying over one of the ports 8 against the corresponding deflector portion vanishes, the cigarette continues its fall and feeding continues until suction is again applied by a further operation of valve 13.
  • FIGURE 3 there is also shown a device 25 connected by a pipe to manifold 12.
  • the device 25 may be any form of suction-operated device and may serve to indicate when feeding of cigarettes is or is. not proceeding and/or to control other functions of a machine in which the feeding device shown is incorporated.
  • device 25 may be a suction-responsive electric switch controlling drive motors for mechanisms below the rollers 1 and guide members 4 different onesof said mecchanisms being required to operate when cigarettes are being fed (suction off) and when they are not (suction on).
  • the feeding device is incorporated in tray-filling machine, while cigarettes are feeding it may be desired to drive downwardly a platform below guide members 4 on which a stack of cigarettes is accumulated, while when feeding of cigarettes is stopped a pusher may be driven to urge said stack from the platform on to a tray.
  • a pusher may be driven to urge said stack from the platform on to a tray.
  • FIGURE 6 a modification which may be employed in place of the device 25 just described.
  • the arm 20, pin 21, and disc 22 previously mentioned As shown in FIGURE 6, the disc 22 has two projecting lugs 26, 27 which are engageable with a fixed stop pin 28 to define the limits of permitted travel of said disc 22; the lug 26. carries the pin 21.
  • a support bracket 29 secured to any convenient fixed part (not shown) of the apparatus carries a switch 30.
  • Said switch 3G' has an operating arm 31 projecting towards disc 22 and so disposed that when the disc 22 rotates anti-clockwise (as seen in FIGURE 6), lug 26 engages the arm 31, and hence switch 36 is operated, just before the lug 27 encounters stop pin 28.
  • Switch 3% is therefore operated whenever the valve 13 is closed, so that no suction is applied to ports 8.
  • the switch 3% is spring biased so that the arm 31 returns to the position shown (the non-operated position) whenever the lug 26 ceases to be in engagement with the arm 31, i.e., when valve 13 is open so that suction is applied to ports 8.
  • a feeding device for rod-like articles such as cigarettes comprising a plurality of horizontal shafts having their axes in a common, substantially horizontal plane, each of said shafts being of polygonal cross-section and being separated from each neighbouring shaft by a space of sufhcient width to allow articles to be fed to pass therebetween, driving means connected to all said shafts and adapted to produce rotation thereof, guide members arranged to define passages constituting prolongations of the spaces between neighbouring shafts, said guide members each including at least one port facing one of said passages, and means for applying suction to said ports so it? that atmospheric pressure urges and holds articles against said ports to block said passages.
