Definitions

  • This invention is a high speed machine for manufacturing cigars, particularly cigar bunches.
  • a cigar bunch is the generally cylindrical structure comprising cigar filler, which may be short or long ller, enclosed in a casing generally termed a cigar binder.
  • the invention is not limited, however, to the manufacture of cigar bunches only, as it is adaptable with minor modifications to the application of a cigar wrapper to the bunch to form a completed cigar.
  • a cigar bunch binder which may be natural tobacco leaf, or reconstituted tobacco, is first cut to a required contour and placed in a predetermined position on the rolling apron of cigar bunch rolling machines.
  • the tobacco filler is deposited on the apron, generally in a loop therein, .and the loop is advanced progressively in a manner to roll the filler into substantially cylindrical form and to enclose the ller in the binder which is applied helically about the ller in the process, to form the cigar bunch. Provision may be made for tapering one end or both ends of the bunch according to the desired shape of the completed cigar.
  • each bunch is produced as a result of an individual rolling operation in which an individual tobacco charge, or bunch filler, as it is termed, is rolled together with the individual tobacco binder.
  • the binder is narrow and relatively long, and since it is wound in several helical turns about the filler, the length of traverse of the rolling apron loop is correspondingly long. Since the rolling loop in the apron must make nearly a complete longitudinal traverse of the rolling table and then must be returned to its original position for the start of a new rolling cycle, the process is understandably slow.
  • Each bunch rolling machine is required to be individually attended by an operator, The machines are expensive, per se, and because of the relatively small output, the cost of bunch rolling operation is a major item of expense in cigar manufacture.
  • the diameter of the cigarettes produced by the method described in the foregoing is constant. Certain refinements have been introduced into the process to change the concentration of tobacco at various places along the cigarette length generally at the ends, however, this change in concentration does not change the cigarette diameter.
  • An object of the present invention is to manufacture cigars having shaped ends at high speed by the continuous rod making process.
  • a first feature of the invention is a mechanism which forms a continuously moving contoured tobacco stream which is thereafter enclosed in a continuously moving web of reconstiuted tobacco to form a continuously moving substantially cylindrical rod having regularly spaced short sections of lesser filler compacted therein.
  • a second feature of the invention is a mechanism which coacts with the mechanism of the first feature to compress the tobacco rod at the positions of lesser compaction to form the rod into a continuously moving length of articulated cigar bunches having tapered ends.
  • a third feature of the invention is a bunch severing device synchronized with the moving :bunches to sever them into individual cigar bunches, each having two tapered ends.
  • the severed individual bunches with tapered ends may later be enclosed in wrappers to form the desired Perfecto shaped cigars.
  • the ller which is showered onto a moving belt to become the moving tobacco stream or braid, before it is enclosed in the binder, is formed of an excess of tobacco over what is required in the bunch.
  • the excess is such that the crosssectional area of each transverse elemental section throughout the entire length of the stream is greater than required in the bunch to be later formed.
  • the stream preferably moves horizontally and the trimmer preferably is arranged so that its position is adjustable vertically regularly to either of two positions with respect to the position of the stream at a predetermined interval. In its upper position is constantly engages the stream, at such a level that it continually removes the excess only.
  • the trimming mechanism is arranged so that at predetermined intervals it is depressed to its lower position so as to trim a larger quantity of tobacco from restricted lengths of the stream. Therefore after trimming, the stream consists of a succession of relatively long higher sections separated by relatively short lower sections.
  • the tobacco filler within the tobacco web cigar rod cover has alternate sections of compacted and less compacted lengths at regularly spaced intervals.
  • FIG. 1 is a schematic of a vertical elevation, partly in section, of the high speed cigar bunch machine of the invention
  • FIG. 2 is a schematic of a vertical elevation, partly in section, of a portion of FIG. 1, drawn to a larger scale, showing the trimming mechanism;
  • FIG. 4 is a schematic plan view of a section of reconstituted tobacco web showing a typical configuration of a section of the web from which portions have been removed to facilitate formation of bunch ends.
  • cigar filler tobacco is delivered to hopper 1 in any convenient manner and is showered therefrom onto endless collection tape 2 which is perforated to permit the passage of air for a purpose to be described hereinafter.
  • Tape 2 is driven by pulley 2A which is connected to a driving source, not shown.
  • Tape 2 is trained over pulleys 2B, 2C, 2D and 2E to keep it taut and runs in the direction indicated by arrow 2F so that it continually passes under the hopper 1 from pulley 2C to pulley 2D in the direction toward the cigar rod former.
  • an excess of tobacco is showered onto tape 2 so that every elemental transverse cross-section of the formed tobacco stream, or braid, is thicker than is required in the finished bunch. This ensures that, after trimming to a predetermined height, the quantity of tobacco in the stream will be just sufficient to provide the required amount in the bunch which is being formed.
  • Hollow chamber 3 is connected by means of the depending neck 3A to a source of suction, not shown.
  • the upper surface of element 3 is perforated so that when perforated endless tape 2, carrying the tobacco stream, or braid, formed :by the showering of the filler tobacco onto tape 2, is advanced over the surface of hollow chamber 3, it is subjected to suction.
  • the amount of suction applied to the braid compresses it, so that after trimming, to be described hereinafter, it will be of substantially uniform density and transverse cross sectional area. After compression, and before trimming however, because of the excess tobacco showered onto the tbelt, the thickness of the stream remains greater than is required to form the bunch. Further, the suction tends to hold the braid securely in position so that it may be operated on advantageously by the shaping wheel in the oscillating trimmer 4, in a manner to be described hereinafter.
  • a continuous belt 7 is driven by a pulley 7A which in turn is driven from a power source7 not shown.
  • the belt 7 is trained over tightening pulleys 7B and 7C, before passing into the cigar rod forming apparatus, and, after emerging therefrom, is reengaged by pulley 7A.
  • a continuous web of reconstituted tobacco 5, which serves as the envelope, or binder, for the bunch is drawn off a reel 5A and passes over tightening pulleys 5B, 5C and 5D to a position over pulley 7C whereat it overlies the continuous belt 7 as it passes into the rod forming apparatus.
  • the cigar rod former comprises tongue 8A, folder 8B, paster SC, and sealer 8D, all well known in the art, which form the tobacco stream and the underlying tobacco binder web progressively from a flat uniplanar sheet, into progressively deeper U-shape and then into a substantially cylindrical shape, with the edges of the web overlapping slightly.
  • the overlapping edges are pasted in the paster 8C to form a longitudinal seam which is sealed in the sealer dD.
  • the rod structure after emerging from the rod former passes between a pair of opposed dies or crimping rollers 11A and 11B.
  • the upper crimping roller 11A is provided with a pair of peripheral die or crimping projections 11C and 11D and the lower crimping roller 11B is provide with a corresponding pair 11E and 11F.
  • These die or crimping projections may be shaped so as to coact to form the bunch ends in any desired manner.
  • Projections 11C and 11E coact as a first pair and projections 11D and 11F coact as a second pair, alternately to form the bunch ends.
  • the rod After passing through the crimper the rod is severed into individual bunches by the cut-off 12 and then passes to the deflector and collecting mechanism 13.
  • an area of the web 5 is perforated at predetermined positions as it is drawn off the reel 5A while being fed to the rod former.
  • the perforations may be advantageously performed by die 6 which is provided with cutting, or punching, projections 6A and 6B which coact alternately with a die element 6C underlying the web 5.
  • the removal of a portion of the web at properly spaced intervals along its length facilitates the wrapping of the bunch at the individual ends thereof where it has been tapered as described hereinbefore.
  • the trimming mechanism 4, the die mechanism 6, the crimping, or end forming, rollers 11A and 11B and the cut-olip mechanism 12 are actuated in 1:1 synchromsm.
  • FIG. 2 Elements in FIG. 2 corresponding to elements in FIG. l are numbered identically.
  • the braid 14, as shown in FIG. 2 is thickest at the right side of the figure, before it is acted on by the trimmer Iwheel 15, At every elemental transverse cross-section to the right of the trimmer wheel, the braid is thicker than required.
  • the trimmer Wheel 15 is normally in such a position as to trim the portion of the braid 14 in the relatively long region between the depressed sections which are to be formed into the tapered ends.
  • the tobacco which is trimmed from the stream is directed through a return duct 16 which is connected to a source of suction, not shown, and is returned to the tobacco source.
  • a drive motor 17, secured in position by means of a bracket bolted to the hopper 1, is provided with a pulley 18 and a corresponding pulley 19 is secured to the shaft of the trimmer wheel 1S.
  • a belt 20 interconnects the two pulleys.
  • a bell crank 21 having a vertical arm 23 and a horizontal arm 24 is loosely mounted for rotation about shaft 25. The left hand end of arm 24 is loosely connected to the shaft of the shaping wheel 15.
  • the upper end of arm 23 is provided with a stud shaft 30, to which a follower 26 is mounted which engages with a rotating cam 27' which 'is secured by bracket 31 to the hopper 1.
  • the bell crank 21 is biased in a clockwise direction by a spring 28 which is connected between the arm 23 and the wall of the hopper 1.
  • roller 26 is oscillated -under the inliuence of the cam and the spring 28.
  • the shaping wheel is reciprocated substantially vertically from its normal position to its depressed position to shape the braid as described heretofore.
  • the trimmings are drawn olf through duct 16.
  • FIG. 3 shows the crimping, or end forming, rollers 11A and 11B and the peripheral projections thereon to a larger scale.
  • the cigar rod comprising the contoured tobacco iller stream encased in the reconstituted tobacco web
  • the crimpers are rotated, in the direction of the arrows in FIG. 3,1 both at such a speed that, when the rod is periodically engaged by the opposed coacting projections on the crimper, the quantity of tobacco passing the projections at the instant is considerably less than required to fill the web casing compactly and the crimpers press the reduced quantity of tobacco between them to form one tapered or otherwise-formed end of each of two adjacent cigar bunches.
  • this operation is facilitated by the perforation of the web, as shown in FIG. 4.
