Definitions

  • 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 sufficient 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move said blocking members between blocking positions in which they block said spaces against passage of articles and withdrawn positions below said shafts.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 optimum cross-sectional shape of the shafts is related to the nature of the articles to be fed, e.g. a square or triangular section shaft would have edges sufficiently sharp to introduce a risk of damage to cigarettes although suitable where the articles to be fed were less easily damaged.
  • shafts of pentagonal or hexagonal section in two preferred embodiments of the invention described in detail hereinafter, the shafts are respectively of regular hexagonal and of pentagonal section. In the latter case, the five faces of each shaft are not plane but slightly concave i.e. in the form of shallow flutes.
  • all the shafts should rotate in the same sense as this secures substantially uniform feed of articles through all the spaces between neighbouring shafts, whereas if alternate shafts were rotated in opposite senses, then alternate spaces would be bounded by two downward-moving and two upward-moving surfaces, tending respectively to promote and discourage passage of articles.
  • the sense in which the shafts rotate also has an influence on the distribution of articles across the whole area immediately above the shafts. If one visualises a device embodying the invention, viewed horizontally looking towards the ends of the shafts, then there will be a tendency for articles lying above the shafts, prior to the passage therebetween, to move to the right if all the shafts rotate clockwise, or to the left if the roation is anticlockwise.
  • Such a feeding device is in use supplied with articles from above and delivers them below the shafts, feeding taking place whenever the shafts are rotating and the blocking members are in their withdrawn positions, and being stopped whenever the shafts are stopped and the blocking members in their blocking positions. It is preferred therefore to provide a common control for the common actuating means of the blocking members and the driving means for the shafts, as this enables feeding to be stopped and started simply and abruptly, which is of advantage if it is desired to feed articles in batches of predetermined size.
  • Feeding devices embodying the invention may be used in a variety of types of apparatus but are notably convenient to use in apparatus for filling boxes, trays or the like.
  • apparatus for filling boxes, trays or the like with cigarettes or other rod-like articles including a feeding device as defined above, including means for delivering articles to a supply hopper immediately above the shafts of the feeding device, a platform below said shafts to receive articles falling therebetween, and elevating means arranged to move said platform vertically between a lowered position and a raised position separated by a distance corresponding to the height of a box, tray or the like to be filled, said elevating means being operable in synchronism with the driving means for the shafts and the common actuating means for the blocking members of the feeding device, so that the shafts rotate and the blocking members are in their withdrawn positions only while the platform is descending from its raised position to its lowered position.
  • the elevating means is arranged to give a rate of descent of the platform which substantially balances the rate at which the height of articles accumulated on the platform increases so that the distance through which articles fall remains sensibly constant and in feeding cigarettes we prefer to keep this distance zero, so that during most of a tray filling operation there is a continuous mass of cigarettes from the platform up between the shafts to the topmost layer of cigarettes in the supply hopper. It is preferred to stop feeding of the articles shortly before the platform reaches its lowest position, to ensure that the tray is not overfilled and once feeding has been stopped, the rate of descent of the platform may be increased.
  • a box, tray or the like open at'the top and over its two long sides may be placed below the feeding means so that the platform descends into it carrying the articles accumulating thereon.
  • the box, tray or the like requires to be pushed laterally in similar fashion and in handling cigarettes it is preferred to provide for engagement of part of the pusher means directly against the box, tray or the like but in handling articles more robust than cigarettes it may be sufficient for the pusher means simply to engage the articles and allow the box, tray or the like to be moved by thrust transmitted through the articles to a side wall of the box, tray or the like opposite the open side thereof through which the platform and pusher means enter.

  • FIGURE l0 is asection on the line XX of FIG- URE 9.
  • the feeding device shown comprises a plurality of parallel hexagonalsection rotatable shafts 1, all of whose axes lie in a common horizontal plane, and associated with each shaft 1 is a blocking bar 2 which may occupy either a withdrawn position below its associated shaft 1,, as illustrated in FIGURE: 1, or a blocking position substantially midway between its associated shaft 1 and one of the adjacent shafts as shown in FIGURE 2.
  • the bars 2 are all carried by a common frame (not shown) so that they are all simultaneously movable between their blocking and withdrawn positions.
  • the spacing between adjacent shafts 1 is such that cigarettes 3 to be fed through the device may only pass one at a time between each pair of adjacent shafts; more specifically, where adjacent shafts are in the positions shown in FIGU'RES l and 2, so that each space between adjacent shafts is bounded by two parallel faces of the shafts, the spacing should not exceed and preferably is less than, twice the diameter of one cigarette 3, while when the spacing is at a minimum, i.e. when the shafts have rotated to such positions that edges of adjoining shafts are in the common plane of their axes, that spacing is not less than the diameter of one of the cigarettes 3.
  • Drivingmeans are provided for rotating all the shafts 1 in the same sense, preferably anti-clockwise to assistant distribution of cigarettes over the width of the hopper 11, and such rotation produces a steady flow of cigarettes between the shafts whenever the bars 2 are in their withdrawn positions (FIGURE 1).
  • said shafts do not provide a positive feed of the cigarettes but rather tend to assist the passage of the cigarettes between the shafts and, more important perhaps, serve to impart a certain agitation to cigarettes above the shafts which prevents jamming of the cigarettes as would occur were the shafts not rotated and the feed accomplished solely by gravity.
  • the shafts being of hexagonal section do not present edges of sulficient sharpness to damage the cigarettes, especially if as is preferable the spacing between adjacent shafts is sensibly greater than the minimum.
  • the tray-filling apparatus shown includes a feedingdevice 10 similar to that of FIGURES 1 and 2, including shafts 1 andblocking bar 2.

  • a hopper 11 supplied with cigarettes by a supply conveyor 12 from which a ramp 13 leads into said hopper.
  • a plinth 14 provides a support for a tray 15 to be filled, the said plinth 14 being so far below the device 10 that the top edge 16 of the tray 15 is only a short distance below said device 10.
  • the tray 15 "has an open top and one open side-the side which is to the right as seen in FIGURE 3iand into the tray there project a platform. 17 arranged for vertical movement from top to bottom of said tray.
  • a pusher plate 18 extends'vertically alongside the tray 15, lying just outside the open side of said tray, and is movable in a horizontal path across the plinth 14, the lower edge of the plate 18 being at a level slightly higher than the inside of the bottom of tray 15.
  • Connected to and movable with the pusher plate 18 are a pair of pusher rods 19, these rods being at a lower level than the lower edge of plate 18 so as to be engageable with the bottom of the tray 15
  • the platform 17 is supported by arms 21 past each. end of the plate 18.
  • a tray filling operation proceeds as follows: with the platform 17 in its highest position, the bars 2 of the feeding device 10 are moved to their withdrawn positions (FIGURE 1) and the shafts 1 are all caused to rotate anticlockwise. Cigarettes start passing through the spaces between theshafts 1 and accumulate upon the platform 17, which itself commences to descend at such a speed that the stack of cigarettes forming on the platform extends up to the lower side of the shafts 1. The tray 15 accordingly fills with cigarettes from the top downwards, and at no time do the cigarettes fall freely.
  • the platform 17 however does not move, so that as the tray and cigarettes move clear of the left-hand (FIGURE 3) edge of the platform 17, the cigarettes drop by a small distance, equal to the thickness of the platform plus any clearance between the platform and the bottom of the tray, and rest within the tray which is then moved away; plate 1 8 and rods 19 are withdrawn and the platform 17 raised, at a higher speed than employed during descent, an empty tray is moved on to the plinth 14, and the whole sequence of events is repeated to fill this further tray.
  • FIG. 1 A pair of chains or belts 22 having projections carrying a common pusher bar 23 are arranged below a support plate 24 adjoining the plinth 14, the pusher bar 23 projecting above the plate 24, serves to propel trays to and from the plinth 14, prior to and after completion of filling operations.
  • Said belts or chains 22 are carried by wheels or sprockets 25 secured on a driving shaft 26 and by idler wheels or sprockets 27 freely rotatable on a shaft 28; the shaft 28 serves as a second drive shaft, having secured to it sprockets 29 engaged with another pair of chains 30 extending to sprockets 31 secured to a transfer shaft 32. Also secured to shaft 32 is a further pair of sprockets 33 which mesh with chains 34 which each pass over three idler sprockets 35 and are connected to the top of the pusher plate 18 by a bar 36. Chains 30 are connected to rods 19 by means of frames 19a which are also secured to the lower edge of plate 18.
  • a further drive shaft 37 carries a pair of sprockets 38 meshed with chains 39 which pass around idler sprockets 40 and each is secured at both ends to one of a symmetri- (rally-disposed pair of sliding blocks 41 which are engaged in slots 42 in a pair of end-plates 43 of the apparatus.
  • the arms 21 supporting platform 17 are scoured to the sliding blocks 41, hence rotation of the shaft 37, first in one sense, then the other, at appropriate times secures the required descent and ascent of said platform at the desired speeds.
  • the several drive shafts 26, 28, 37 are driven in shitably timed relation with one another and with operation of actuating means for the shafts 1 and bars 2 of the feeding device 10 so as to obtain the sequence of opera tions explained above.
  • a photo-electric cell unit 44 aligned with a hole 45 in the opposite wall outside which hole a lamp 46 is mounted.
  • the lamp 46 is lit and therefore the unit 44, in conjunction with electrical circuits (not shown) will in known manner produce an electrical output indicating Whether or not the light from the lamp is blocked from reaching the photo-electric cell unit.
  • the said electrical output will indicate whether or not the cigarettes in the hopper extend above the said level and the said circuits are connected to control the drive of the apparatus, which preferably is an electric motor, so as to stop the apparatus whenever light reaches the unit 44. This is desirable as a certain minimum height of the stack of cigarettes above the shafts 1 is required to ensure a proper feed of cigarettes between said shafts.
  • an agitator comprising a number of parallel bars 47, extending parallel to shafts I, mounted in a rectangular frame 48.
  • the frame 48 with its bars 47 is arranged to reciprocate horizontally at right angles to the length of bars 47 whenever the bars 2 are withdrawn and shafts 1 rotating so that the bars 47 cross and recross the paths of cigarettes falling from between shafts 1 and thus the distribution of cigarettes on the platform 17 is assisted.
  • FIGURES 5 to 10 for convenience of comparison those parts which correspond closely to parts of the device and apparatus of FIGURES 1 to 4 will be given a reference number one hundred higher than that applied to the latter parts, while those parts shown in FIGURES 5 to 10 not so corresponding will be given reference numbers not less than two hundred; for example in FIGURES 1 to 4 the hexagonal shafts carry the reference 1 and in FIGURES 5 to 10 corresponding shafts are indicated by reference 101; but the parts marked by reference 201 in FIGURES 5 to 10 are not however so related to the shafts 1.
  • the feeding device illustrated comprises parallel rotatable shafts 101 and associated blocking bars 102.
  • Cigarettes 103 pass between the shafts whenever bars 102 are in their Withdrawn positions, i.e. as shown in FIGURE 5.
  • the shafts 101 are basically of regular pentagonal section, but the faces of the pentagon are slightly concave, in the form of very shallow flutes, also the corners of the pentagon are chamfered off to remove sharp edges which could damage the cigarettes 103.
  • the shafts 101 are provided with driving means, as shown in FIGURES 7 and 9, comprising coupling shafts 201, bevel gears 202, 203, a common cross-shaft 204, bevel gears 205, 206, 207 and a driving shaft 208. More specifically, each shaft 101 has one of its ends coupled by a tongue-and-slot joint to one end of an associated coupling shaft 201 which is aligned with and forms an extension of the shaft 101. The other end of the shaft 201 carries a bevel gear 202 which meshes with a bevel gear 203 secured to the common cross-shaft 204.
  • One end of the cross-shaft 204 carries a bevel gear 205 which meshes with two bevel gears 206, 207, carried on the driving shaft 208 which, during operation of the apparatus, is rotated by any convenient prime mover (not shown), preferably an electric motor.
  • the two bevel gears 206, 207 are not secured directly to the shaft 208 but are connected to the shaft via freewheels (i.e. unidirectional clutches) 209, 210 and driving rings 211, 212 respectively, the driving rings being secured to the shaft 208.
  • the freewheels are arranged in opposition, i.e. so that upon rotation of shaft 208 in one direction the freewheel 209 provides a driving connection between ring 211 and gear 206 while freewheel 210 allows the ring 212 to turn without transmitting any drive to gear 207, rotation of the shaft 208 in the opposite direction serving to drive gear 207 but not gear 206.
  • gears 206, 207 is driven and hence drive is transmitted to gear 205.
  • gears 206, 207 mesh with the gear 205 at diametrically opposed positions, rotation of gear 206 in one direction and rotation of gear 207 in the opposite direction produce similar rotation of gear 205.
  • This arrangement of the gears and freewheels therefore, causes shaft 204 (and hence shafts 101) to rotate in a desired direction whenever shaft 208 is rotating, irrespective of the direction of rotation of the latter shaft.
  • the shaft 208 also carries a further pair of freewheels 213 and 214 associated with a driving ring 215 and a cam 216.
  • the cam 216 is rotatable upon and relative to the shaft 208 and has a projecting integral central boss 217 on which the freewheels 213 and 214 are mounted.
  • the freewheel 213 is also secured to the ring 215 (which is itself secured to the shaft), while the freewheel 214 is also secured to a fixed bracket 218.
  • the two freewheels 213 and 214 are so disposed that when shaft 208 rotates in one direction, freewheel 213 provides a driving connection between ring 215, rotating with the shaft, and cam 216, but when the shaft rotates in the opposite direction the cam 216 is not driven.
  • the shaft 208 also carries a three-lobed cam 219 (FIG- URES 8 and 9) which is fixedly secured to said shaft so as to be rotated whenever the shaft rotates, in either direction.
  • a follower roller 220 rides on the cam 219 and is carried by an arm 221 which is pivoted at its upper end to a fixed stud 222, carries the roller 220 at about its mid-point, and at its lower end is bifurcated to embrace a rod 223 connecting two horizontally reciprocable bars 148.
  • Said bars 148 are also connected by a plurality of further rods 147; the rod 223 and rods 147 extend parallel to shafts 101, while bars 148 extend at right-angles to said shafts, the bars 148 and rods 223, 147 all being horizontal and lying somewhat below the level of shafts 101.
  • the rods 223, 147 all project through the bars 148 and therefore have projecting end portions such as 223a (FIGURE 9) which are received in a pair of horizontally-extending grooved members 224 forming part of the frame of the apparatus.
  • the said platform 117 is horizontal and is carried by a frame 121 secured to two vertically slidable blocks 141; each of said blocks 141 is associated with 'an endplate 143 of the apparatus and constrained to move vertically by guides (not shown) carried by the associated end-plate.
  • Each of the blocks 141 has both ends of a chain 139 secured to it, the chains 139 passing round idler sprockets 140-and drive sprockets 138, the latter being carried by drive shafts 137 of electric motors 225.
  • the motors 225 are energised whenever cigarettes are falling between shafts 101 so as to produce a relatively slow downward movement of the platform 117, whereby as cigarettes collect on said platform the top of the growing stack of cigarettes is always just below the level of the lowest points of shafts 101.
  • a plinth 114 is provided directly below the shafts 101, just below the lowest level that the platform 117 can reach, to carry a tray 115 to be filled.
  • the tray to be filled preferably has no side walls, as shown, but in any event must be open on one side (the left as viewed in FIGURE 7) and at the top, so that the platform 117 may descend into said tray.

It can readily be seen (FIGURE 7) that rotation of cams 234 and 235 produces horizontal reciprocation of the plinth 114.
  • a pusher plate 118 stands vertically alongside tray 115, and is carried by a support 236 which is horizontally slidable on a support rod 237. Tilting of the plate 118 is prevented by projecting flanges 238 (FIGURE 8) ofangle-section horizontal members of the apparatus frame, which flanges are engaged by the ends of the lower edge of the plate 118.
  • Said plate 118 has a projecting web 239 on the face remote from the region traversed by platform 117, said web 239 being connected by a pin-andslot connection indicated at 240 to a double-arm lever 241 pivoted on a shaft 242 and carrying two cam-followers 243 riding on the cams 234 and 235.
  • the cams 234, 235 are both secured to a common shaft 244, and it will be apparent that rotation of cams 234, 235 will produce horizontal reciprocation of the plate 118 in timed relation to the aforementioned reciprocation of plinth 114.
  • the shaft 244 also carries a third cam 245 against which a cam follower 246 carried by one end of a lever 247 bears.

  • the other ends of said rods 227 are carried by a mounting block 249 pivotally secured at 250 to the frame of the apparatus.
  • the cam 245 is so shaped as to allow the yoke 248 to drop slightly for a short period once per revolution of the shaft 235, this movement naturally taking place in timed relation to the horizontal reciprocation of plinth 114 and plate 118 due to the fact that cams 234, 235 and 245 are all carried by and rotatable with the same shaft 244.
  • the blocking bars 102 require to be moved between the position of FIGURE 5 and that of FIGURE 6; referring again to FIGURES 9 and 10, this is accomplished in response to the movement of the cam 216 previously described.
  • Two cam followers 251, 252 ride on said earn 216 and are both carried by a block 253 from which two bars 254, 255 extend horizontally above and below the coupling shafts 201 and at right-angles thereto.
  • the bars 254, 255 have rack teeth formed in lower and upper faces respectively, as indicated at 256 (FIGURE 10) which mesh with a series of pinions 257 carried by, but rotatable relative to, the coupling shafts 201.
  • Each pinion 257 carries, eccentrically, one end of the blocking bar 102 associated with the shaft 101 coupled to the coupling shaft 201 on which that pinion is carried, the other end of said bar 102 being similarly carried by a similar pinion 258 carried by, but rotatable relative to, the ends of shafts 101 remote from the coupling shafts 201.

  • the upper bar 254 has teeth meshing with pinions 257 in the left-hand half of the apparatus while the lower bar 255 has a complementary arrangement; thus when rotation of cam'216 causes both bars to move to the right (still as seen in FIGURE 8), say, the pinions 257 in the left half will rotate clockwise, and those in the right half will rotate anticlockwise.
  • Pinions 258 mesh with rack teeth on a similar pair of upper and lower bars, but in this case the upper bar has its teeth on its right-hand part, the lower bar has its teeth on its left-hand part.
  • the shafts 101 are not all driven in the same direction.
  • the bevel gears 203 lie to the right of the gears 202 with which they mesh, and this is true of all the gears 203 contained in the left half of the assembly of shafts 101 (as seen in FIGURE 8), but in the right half, the bevel gears 203 lie to the leftof their associated gears 202; thus the shafts 101 in the left half all rotate in one direction while the shafts 101 in the right half rotate oppositely, the respective directions of rotation being anticlockwise and clockwise, as seen in FIGURE 8.

  • the shaft 208 (which has hitherto been rotating in such direction that the shafts 101 were turning but not the cam 216) is caused to rotate in the reverse direction for a halfrevolution.
  • Cigarettes commence falling between shafts 101 on to platform 117, and simultaneously motors 225 are energised so that platform 117 starts to descend, its rate of descent being equal to that at which the depth of cigarettes stacked on the platform 117 increases.
  • Shaft 208 after it half-revolution in the reverse direction, continues forward rotation so that shafts 101 are turning to assist passage of cigarettes therebetween and bars 148 are reciprocated by cam 219, causing rods 147 to cross and recross the paths of the falling cigarettes to produce even distribution on the platform 117.
  • Shaft 244 continues to turn until it has completed one revolution, whereupon it stop, plinth 114 and plate 118 having then returned to the positions shown in FIG- URE 7; thereupon motors 225 are again energised, to run at higher speed and in the reverse direction, causing platform 117 to ascend quickly to its highest position.
