Definitions

  • the present invention generally relates to multi-station cigar wrapping machinery having a cigar bunch supply station, a cigar wrapper supply station, and a conveyor for conveying the bunches to a cigar wrapping station at which the wrappers are spirally applied about the bunches. More particularly, the present invention relates to respacer and/or reorienter feed arrangements for and methods of continuously feeding cigar wrappers in proper spaced-apart relationship and/or orientation to the wrapping stations of such machinery.
  • Still a further object of the present invention is to increase production efficiency by handling each successively leading wrapper in its turn.
  • Yet another object of the present invention is to convey wrappers through the wrapping station at a different spaced-apart relationship selected for optimum wrapping purposes.
  • a further object of the present invention is to respace the wrappers from said predetermined spaced-apart relationship to said different spaced-apart relationship in an efficient, smooth, fluid, continuous and reliable manner.
  • Still a further object of the present invention is to reorient the wrappers from said predetermined relative orientation to said different relative orientation in an efficient, smooth, fluid, continuous and reliable manner.
  • Another object of the present invention is to maintain the relative spacing between the wrappers during their passage through the cigar wrapping station substantially constant.
  • Yet another object of the present invention is to reliably pickup each successively leading wrapper in its turn by suction and to reliably release each such suction-held wrapper in a gradual lengthwise manner as the respective wrapper enters and passes through the wrapping station.
  • the machine includes a cigar wrapper supply station for supplying cigar wrappers; conveyor means for continuously and sequentially conveying a series of cigar wrappers, one after another, along a wrapper transport path to the wrapper supply station, said wrappers being conveyed along the wrapper transport path in a predetermined arranged relationship in which successive wrappers are located relative to one another at positions selected for optimum compact transport purposes; a cigar bunch supply station for supplying cigar bunches; means for continuously and sequentially conveying a series of cigar bunches, one after another, from the bunch supply station along a bunch feed path towards the cigar wrapping station; and means at the cigar wrapping station for spirally applying wrappers from the wrapper supply station about the bunches to thereby form spirally wrapped cigars.
  • the feed arrangement and method includes continuously and sequentially moving each successively leading wrapper, one after another, relative to its next successivqly trailing wrapper, from its respective optimum compact transport position along a wrapper feed path and through the cigar wrapping station.
  • the wrappers are conveyed along the wrapper feed path through the cigar wrapping station in another different arranged relationship in which successive wrappers are located relative to one another at different positions selected for optimum wrapping purposes.
  • each successively leading wrapper on the wrapper feed path registers with each successively leading bunch on the bunch feed path at the cigar wrapping statioa at substantially the same time.
  • cigar wrapping is performed in an automatic and non-stop manner.
  • the moving means is operative to respace each successively leading wrapper from its respective optimum compact transport position, in which it is spaced at a first distance relative to the next successively trailing wrapper, to the respective optimum wrapping position, in which it is spaced at a different second distance relative to the next successively trailing wrapper.
  • the second distance is greater than the first distance. In accordance with another embodiment of the invention, the second distance is smaller than the first distance.
  • the moving means is also operative to reorient each successively leading wrapper from its respective optimum compact transport position, in which it is oriented at a first orientation relative to the next successively trailing wrapper, to the respective optimum wrapping position, in which it is oriented at a different second orientation relative to the next successively trailing wrapper.
  • the wrappers are oriented in end-to-end alignment in said first orientation and are oriented in a generally V-shaped chevron-type alignment in said second reorientation.
  • the respacing and reorienting aspects of the moving means may be performed either separately or simultaneously, as desired.
  • the spacing between wrappers as they pass through the wrapping station is maintained essentially constant and uniform. This feature assures that the wrapping of a wrapper about a bunch will be performed in a continuous, smooth, fluid, automatic, uniform manner.
  • each wrapper is reliably picked up in its turn, by suction at the wrapper supply station and conveyed towards the wrapping station.
  • Each successively leading wrapper is thereupon reliably released in a continuous, gradual, uniform manner lengthwise along each wrapper as the latter enters and passes through the wrapping station.
  • Fig. 1-15 illustrate one preferred embodiment of an improved feed arrangement for and method of continuously feeding cigar wrappers to a cigar wrapping station of a multi-station cigar wrapping machine; Figs. 16-22 illustrate another preferred embodiment; and Figs. 23-25 illustrate yet another preferred embodiment.
  • the wrappers may be initially supplied to the wrapping machine in many forms.
  • the wrappers may be individually pre-cut natural tobacco material, each wrapper being oriented and placed on a carrier tape for optimum utilization of the tape, e.g. for compact transport purposes.
  • the wrappers may be supplied as a strip sheet of reconstituted tobacco, the makeup of such sheet being well known in the art.
  • a typical sheet may include particulate natural tobacco which has been attrited from natural leaf material and embedded in a matrix of smokable material, or the sheet may constituted by pieces of natural tobacco glued or cemented end-to-end.
  • Reconstituted tobacco is preferred if the same is acceptable for a finished cigar, as it conventionally is for inexpensive cigars inasmuch as wrappers of reconstituted tobacco are uniform in consistency, strength, dimension and appearance, thereby making it easier to design a machine to handle such wrappers in high speed mass production as compared to wrapper sheets made up of joined or carried pieces of natural tobacco.
  • the sheet form i.e. without a carrier tape, the sheet must be conveyed to and past a rotary cutter or the like, to thereby cut the wrappers to the appropriate shape necessary for wrapping cigar bunches.
  • Fig. 3 shows a plurality of wrappers 11, 12, 13, 14 mounted on a carrier tape or strip 10 which is elongated in direction of arrow D and which is unwound from supply roll 15.
  • the wrappers are inclined relative to the elongation and direction of movement of the strip 10.
  • Fig. 3 shows the preferred manner of supplying wrappers for the embodiment of Figs. 1-15. If the individual wrappers were arranged relative to each other in end-to-end alignment on a carrier tape rather than the side-by-side alignment of Fig. 3, then this would be the preferred manner of supplying wrappers for embodiments of Figs. 16-22 and of Figs. 23-25.
  • the wrappers need not be pre-cut and carried on a tape, but may equally be supplied in sheet form to a conventional rotary cutter for pre- cutting for any of the aforementioned embodiments.

  • the frame includes a horizontal mounting plate 16 having height-adjusting feet 18 mounted on the floor 19, a vertical mounting plate 17 connected to the horizontal plate l6, and a pair of inclined reinforcement struts 21 connected to both plates to support the vertical plate 17 in a generally upright orientation.
  • First or right hand wrapper feed reel 22 is mounted on shaft 23 for rotation about axis E-E in circumferential direction of arrow F.
  • Second or left hand wrapper feed reel 24 is mounted on shaft 25 for rotation about axis G-G in circumferential direction of arrow H.
  • a roll 15 (see Fig. 3) is mounted in coiled form on each reel.
  • Links 26, 27 respectively mount right feed reel 22 and left feed reel 24 for limited angular pivotal movement about stub shaft 28.
  • Control links 29, 30 each have cam surfaces which cooperate with cam follower units 31, 32 which are operative to constantly urge the leading strips 10 on both the right and left feed reels 22, 24 into affirmative engagement with the respective peripheral surfaces of right hand transfer roller 34 and left hand transfer roller 36.
  • Fig. 3 the pre-cut wrappers 11, 12, 13, 14, as noted above, are mounted on carrier strip 10 which is unwound from the roll 15 in direction of arrow D.
  • the wrappers are elongated and oriented at an angle of inclination on the order of 45° relative to the direction of advancement.
  • Each wrapper has a leading or tuck end region and a trailing or flag end region.
  • wrapper 12 has flag end region 12a which first converges in direction away from tuck region 12b, and then terminates in a curlicue having a generally circular outline.
  • the shape of the flags is not unique to the present invention because it has been used before in conjunction with semi-automatic equipment.
  • Tuck end region 12b tapers to an apex which is bounded by edges 12', 12". It will be noted that edges 11", 12", 13", l4" are colinear and that edges 11', 12', 13', l4' are substantially parallel to each other.
  • the wrappers are spaced apart from each other by a predetermined distance. Any distance including a distance of zero magnitude, i.e. where successive wrappers are contiguous with each other, will do. In a preferred application, the wrappers are spaced approximately 2 1/4 inches apart as measured along the direction of advancement, i.e. points I and J are spaced approximately 2 1/4 inches apart.
  • the wrappers are placed on the strip such that their veins are face down.
  • the flag of wrapper 11 is lifted up to expose the veins on the underside of the wrapper which ordinarily would contact the strip 10.

  • the spacing between the wrappers of Fig. 3 is selected for optimum compact transport purposes. The closer together the wrappers are spaced, the more compact will be the size of the roll -- a feature which is very advantageous to minimize handling, shipment and manufacturing costs.
  • the individual strips 10 on feed reels 22, 24 are successively entrained about a portion of the circumference of transfer rollers 34, 36 which are mounted for rotation in circumferential direction of the arrows K and L, respectively.

  • Takeup reels 44, 46 are journaled for rotation about axis M-M and are driven in circumferential direction of arrows N and 0 by drive motor 50 via belted drive assembly 49.
  • Guide fenders 51, 52 facilitate the rewinding of the strips, and tension assemblies 53, 54 exert the proper spring tension on the strips as they are being rewound on takeup reels 44, 46.
  • cigar wrappers one after another, are being delivered to stations 40, 42.
  • the improved feed arrangement 100 is operative for continuously feeding the wrappers to the cigar wrapping station 55 at which the wrappers are spirally applied about cigar bunches to thereby form spirally-wrapped cigars.
  • the cigar bunches are delivered to the wrapping station 55 in the following manner.
  • the magazine or hopper 56 constitutes a cigar bunch supply station in which a considerable number of cigar bunches are disposed in an orderly array, i.e., each bunch is horizontally oriented and vertically stacked generally one above another.
  • Bunches may come in single or double length sizes.
  • a single bunch has a non-cylindrical, tapering, hemi-ovoidal end region which is adapted to be received in a smoker's mouth, and an opposite cylindrical fire end region which is adapted to be ignited by the smoker.

  • a double bunch consists of two single bunches coupled at their common fire ends.
  • two wrapper supply stations 40, 42 are provided, and the feed arrangement 100 is operative to deliver two wrappers in chevron configuration to the wrapping station 55.
  • the wrapping means at the station 55 wraps both wrappers simultaneously about the double bunch. Subsequently, the wrapped double bunch is slit to form two wrapped cigars.
  • the machine may also include a single wrapper supply station and a single wrapping head for single bunches or for double bunches, or successive wrapping heads for single or double bunches, the highest production speeds being achieved when double wrapping heads for double bunches are employed.
  • Such double-headed twinned-bunch wrapping machines may reach speeds on the order of 400 cigars wrapped per minute.
  • Discharge chute 58 leads the bunches in single file and still in horizontal orientation to the bunch input transport means 60 which constitutes a transfer wheel mounted on shaft 59 for rotation about axis T-T.
  • the wheel 60 has bunch-receiving pockets operative to hold each bunch, in its turn, and transport the same in a continuous and sequential manner from the bunch supply station 56 along a bunch feed path towards the cigar wrapping station 55.
  • bunch input transport means forms no essential part of the present invention, a further description of the structural and functional features thereof is not believed to be necessary.
  • Such bunch input transport means are entirely conventional and are well known. For example, reference can be made to U.S.L.P. 4,103,692, the entire contents of which are hereby incorporated by reference herein.
  • the bunches are delivered by wheel 60 to diagrammatically-illustrated rolling nest chain assembly 62 which is essentially a stretch chain entrained about three rollers.
  • Carrier plates are mounted on the chain and each has a bunch-receiving pocket which is conveyed to, through and past wrapping station 55.
  • Structural and functional details of such rolling nest chain assemblies are likewise conventional and, therefore, a further description thereof is not believed to be necessary.
  • bunches are delivered ' to the rolling nest chain at input path portion 64, that wrapping of a bunch with a wrapper essentially begins in the vicinity of path portion 66, that wrapping of a bunch with a wrapper essentially terminates in the vicinity of path portion 68, and that bunches are discharged from the rolling nest chain at output path portion 70.

  • Platen 114' has two legs each having a slightly circumferentially foraminous wrapper-carrying surface which is perforated in a predetermined pattern which corresponds to the outline of a single wrapper. As best shown in Fig.
  • the perforated outlines of the flag ends of the two wrappers are located at the extreme remote ends of the chevron platen ll4', and the perforated outlines of the tuck ends are located at the apex of the platen 114'.
  • the ring carriers of all of the platen assemblies are spaced in axial direction along shafts 118, 119, and each ring carrier is in sliding sealing contact with its neighboring ring carrier.

  • the bell crank link performs limited pivoting angular movement about the axis defined by the pivot pin 189, for the purpose explained below.
  • the rotor 122 and the drive gear 126 are turned by the non-illustrated motor and belt drive arrangement about the drum axis P - P .
  • the pinion 140 is rotated about its longitudinal pinion axis R-R due to the meshing engagement between the teeth of set 130 on the gear 126 and the splined teeth on pinion 140.
  • pinion axis R-R is offset in radial direction from drum axis P-P due to the offset journals 134, l44.
  • rotating pinion 140 rotates the drive plate 152 about the drive axis S-S which is radially offset from both the drum and pinion axes.
  • the rotary motion of teeth set 130 is converted to the rotary motion of teeth set 154 and, as best shown in Fig. 7, this eccentric motion is responsible for moving the various platen assemblies relative to each other to the relative positions shown in Fig. 7
  • each cam follower e.g., roller 194
  • each slider bar is forced to travel in its associated radially-extending slide track.
  • each bar post is compelled to follow the circular path of its associated cam roller and, therefore, each bar post and its associated slider bar are moved through a different distance along their associated slide tracks.
  • the torque of the rotor is transmitted via the pusher assemblies to thereby generate a force component which pushes the platen assemblies in circumferential direction.
  • the extent of angular movement through which each platen assembly is moved depends on the location of the respective slider bar in its slide track. As shown in Fig. 7, the slider bar of platen assembly 105 is furthest away in radial direction from the drive axis and assembly 105 and is essentially contiguous with its neighboring platen assemblies 104, 106.
  • the slider bars of platen assemblies 113, 114 are closest relative to the drive axis and these are spaced at the greatest angular distance relative to their neighboring platen assemblies 112, 115.
  • the respacer mechanism would normally generate a sinusoidal-type variation in the angular distance between the platen assemblies, i.e. the angular distance between platen assemblies 105 and 106 would be a minimum value, the angular distance between assemblies 106 and l07 would be slightly greater than the minimum value, and so on, until the maximum angular distance would be obtained between platen assemblies 113 and 114.
  • the angular distance would progressively decrease in value from the aforementioned maximum value to smaller values as one measures the distance between assemblies ll4 ... 117 and 101 ... 105.
  • the present invention proposes to modify this sinusoidal characteristic inasmuch as it is advantageous to maintain the relative spacing between platens relatively constant, particularly in the wrapper pickup zone A and the wrapping zone C (See Fig. 7).
  • the V-shaped platen is supplied with two wrappers, one from supply station 40, and the other from supply station 42. These supply stations are spaced laterally and longitudinally apart from each other and, therefore, it is very desirable not to change the spacing between platens in pickup zone A in order to reliably position the wrappers on the platens.
  • the paste station 95 which is operative for applying glue on zones 33, 35 (see Fig. 3) of the wrappers is located adjacent the pickup zone in order to uniformly apply the paste on the wrappers in a controlled, uniform manner.
  • maintaining the relative angular spacing between successive platens insures uniform and proper wrapping of the wrappers.
  • the limited pivoting action of the bell crank links modifies the aforementioned sinusoidal characteristic to the flattened characteristic shown graphically in Fig. 8.
  • the limited angular pivotal movement of each link about its pivot pin permits the angular spacing to reach its maximum and minimum values at a constant level for a longer time period as compared to the sinusoidal characteristic.
  • the platen assemblies are maintained substantially constant at a minimum value, i.e. zero angular spacing in which the platen assemblies are contiguous with each other in the so-called "closed" position.
  • the platens are maintained substantially constantat a maximum value, i.e. a value selected for optimum wrapping purposes, the platens being spaced apart in the so-called "open" position.
  • the angular spacing between platen assemblies increases gradually as one moves from platen assembly 109 to assembly 112, and thereupon decreases gradually as one moves from platen assembly 115 to assembly 101.
  • wrappers from transfer rollers 34, 36 are transferfed to the right-and left-hand legs of each successively leading V-shaped platen. This transfer is accomplished by generating a sub-atmospheric pressure at the wrapper-carrying surfaces of each platen at the pickup zone to thereby retain the wrappers on the associated platen by suction.
  • the suction is maintained even though the platen assemblies are moved apart of each other.
  • the suction must be gradually terminated in order to progressively release the wrapper along its length to permit the wrapping operation to be performed.
  • the cylindrica body portion of rotor 122 has a plurality of radially-extending vacuum ports 200, each port having one end in communication with the hollow rotor interior in which a sub-atmospheric vacuum condition is maintained, and an opposite end located at the outer circumferential surface of the rotor and operative for communicating the vacuum to the exterior of the rotor.
  • the vacuum ports preferably twelve in number, are equi-angularly and equi-distantly spaced about the drum axis P-P.
  • the stator 120 surrounds the rotor and has an inner circumferential surface in sliding sealing engagement with the outer surface of the rotor 122.

  • This progressively-applied suction force is operative to secure a wrapper in fixed position and in successive lengthwise manner on the platen.
  • Platen assemblies 101 - 109 are pressed tightly and sealingly against each other in the wrapper pickup zone A, and this contiguous sealing contact prevents excessive vacuum loss between the assemblies. It is in this "closed" platen spacing that the wrappers are transferred in veins-up condition from the transfer rollers 34, 36 at the common points of tangency (i.e., at the wrapper supply stations 40, 42) to the platens.

  • glue types at other sites of application for the glue are likewise possible and varies according to design considerations.
  • Platen assemblies 110, 111 are angularly spaced relative to each other, and therefore the vacuum can no longer be supplied by a single vacuum chamber without vacuum loss through the area of separation between the assemblies. Therefore, the vacuum channels 204, 206, 208, 210 in the stator are narrower, and these individual channels are appropriately angled to connect the openings in the base wall of the support with the proper opening in the rotor. As the assemblies 109-111 advance and increase in relative spacing, the angle of inclination of the narrow channels are changed to fit the advanced position.
  • the channel spacing has been designed so that the bottom wall of each support always communicates with at least one of the channels in the stator and with one vacuum port 200 in the rotor.
  • platen assemblies 109-111 maintain a vacuum condition at their respective wrapper-carrying surfaces no matter where they are located along the transition region B. The wrappers do not fall off the platens, because the suction force is always present, and because there is no appreciable vacuum loss to the space between the assemblies even though the latter separate.

  • open ends 244, 246, 248 respectively pass the 320 °, 342 0 and 6 0 marks
  • the second, third and fourth compartments no longer communicate with the vacuum source, and therefore, the respective trailing portions of the wrapper are sequentially released to thereby permit the wrapping operation to be completed in sequential manner.

  • the positive pressure in all of the internal ports is operative to affirmatively blow out any particle debris blocking the apertures in the wrapper-carrying surfaces of the platen. It will be appreciated that the wrapping machine does not operate in a "clean" room free of airborne particulate matter and, indeed, since the machine is handling a natural product, i.e. tobacco which sheds particles and, furthermore, since the suction ports are, at various parts of their travel, exposed to a particle-laden atmosphere while suction is present thereat, the passages associated with these ports cannot be prevented from inspirating foreign material. It, therefore, is desirable to periodically clean these ports.
  • This purge operation may be set up on a time basis in order to minimize the use of the air pressure source.
  • the positive pressure source is also connected to a non-illustrated tuck pop-off port.
  • the open end 220 of the tuck pop-off port communicates with the open end 252 of passage 232.

  • Piston 254 is mounted for sliding movement in sleeve 256 which is threadedly mounted on the platen.
  • Piston 254 has an upper circular wall 258 which underlies a portion of both tuck ends of the wrappers.
  • the positive pressure in passage 232 is operative to push the piston 254 such that its upper wall 258 is raised above the wrapper-carrying surface, thereby lifting the leading ends of the wrappers. This action permits the wrapping operation to begin in a reliable, controlled manner.
  • the tension spring 260 returns the piston back to its original position when the positive pressure source is removed.
  • the wrappers and their carrier tapes are transferred by suction to the transfer rollers 34, 36, and thereupon the wrappers are continuously and sequentially conveyed to the wrapper supply stations 40, 42, at which the individual wrappers are transferred by suction to the carrier drum 100 at their common points of tangency with the platens in the wrapper pickup zone.
  • the suction means associated with the drum maintains positional control of the wrappers to, through and past the paste station 95, and thereupon far enough into the wrapping station 55 to prevent any part of a wrapper from being free to change its position except for the wrapping operation.
  • the suction maintains positional control of the wrappers by progressively releasing successive portions of the wrappers as they are wrapped due to the timing between the rotor and the stator described above.
  • bunches at bunch supply station 56 continuously nudge the leading bunch through chute 58 towards the input transfer wheel 60 which picks up each leading bunch in its turn and conveys it to the wrapping station where synchronization is made with each leading pair of wrappers even though the platens rotate about the drum axis at a changing rate of speed.
  • the continuous movement of the bunches and the wrappers through the machine overcomes the semi-automatic prior art machines; that is to say, the wrappers move continuously from the time they first are loaded on the machine until the time they are wrapped about the cigars and, similarly, the bunches move continuously from the bunch supply station 56 througt the machine. All operations of the present invention are performed upon and by moving wrappers and bunches, and the moving parts are not actuated intermittently nor moved by hand with a concomitant slowdown in operations.
  • the spiral application of the wrappers about the bunches is performed continuously on any given bunch and its associated wrapper.
  • such wrapping action is practiced upon successive bunches and wrappers in an overlapping manner.
  • the wrapping of a succeeding bunch is started and if desired, while the first two bunches are being wrapped but are at progressively different stages of the wrapping operation, another bunch or other bunches may have progressed part-way through their wrapping operations, so that at any given time, more than one bunch is being wrapped and having wrappers spirally applied thereto.
