Definitions

  • the present invention relates to the art of making cigars and more particularly to a method and apparatus for wrapping cigars.
  • the invention is particularly applicable to wrapping simultaneously two cigars with natural tobacco leaf wrappers and it will be described with particular reference thereto; however, it is appreciated that the invention has broader applications and may be used in wrapping a single wrapper around a cigar.
  • synthetic wrappers can be used with the present invention.
  • Two wrappers may be integrally formed; however, this does not depart from the intended definition of a wrapper which is the outer covering for a single cigar. In some instances two wrappers are used simultaneously. They may be formed integrally or they may be separate and held in a given mutual relationship.
  • the term "sheet" when used to define the wrappers relates to their geometry and applies equally to natural and synthetic wrappers.
  • a generally cylindrical body known as a bunch
  • a wrapper which has the appearance of a natural tobacco leaf.
  • This wrapper can be formed from a natural tobacco leaf or from synthetic material having a similar appearance.
  • These wrappers generally include a first end, known as the tuck or tuck end, that is adjacent the fire end of a completed cigar and a second end, known as a flag or flag end, which is ultimately wrapped at the mouth end of a completed cigar.
  • the bunch has an outer covering which supports the inner filler forming the insides of the cigar.
  • the wrapper is a decorative cover element which is placed around the bunch in a spiral fashion to present the cigar appearance identified by consumers.
  • An objective of designing and manufacturing an automatic machine for wrapping cigars is to provide an arrangement for removing wrappers from the standard wrapper storage bobbins and for moving the wrappers to a position where they engage a cigar bunch and are wrapped around the bunch mechanically.
  • One machine for accomplishing this operation is illustrated in United States Letters Patent 4,103,692.
  • This prior patent is incorporated by reference herein for background information to show details of an automatic cigar wrapping machine of the general type employed in the preferred embodiment of the present invention.
  • This prior patent illustrates an arrangement for automatically wrapping cigar wrappers from a supply bobbin onto cigar bunches. In this patent, the tuck end is secured to one end of the cigar and the cigar is rotated as it translates.
  • the bunch is rotated as it is translated.
  • the support structure for the wrapper is moved in the same direction as the support structure for the bunch during the wrapping operation so that the wrapper can be held by vacuum in a preselected position until it is pulled from the vacuum support element onto the rotating bunch to produce a desired wrapping operation.
  • United States Letters Patent 3,794,048 illustrates a wrapping operation wherein synthetic wrapper leaves are used.
  • a non-automatic cigar wrapping device is shown in United States Letters Patent No. 3,111,950 wherein a rotating bunch moves over a wrapper that is wrapped in two directions on a single bunch.
  • the present invention relates to a method and apparatus for wrapping cigar wrappers onto cigar bunches, which method and apparatus does not require respacing when the wrappers are supplied by standard wrapper bobbins, such as used in storing wrappers formed from natural tobacco leaves, or an arrangement for spacing adjacent wrappers when synthetic wrapper leaves are provided from a spool of synthetic material cut into wrappers prior to being directed to a wrapping mechanism. Consequently, although the invention is particularly adapted for use with the closely spaced cigar wrappers on a storage bobbin, it is also advantageous for use with equipment using wrappers cut from synthetic material. In both of these instances, prior wrapping apparatus have required sufficient spacing between the adjacent or successive wrappers as they are directed to the wrapping position of an automatic cigar wrapping machine. This is required because of the necessary spacing between bunches when they are individually rotated.
  • a method of wrapping an elongated, flat sheet cigar wrapper having a first end, a second end, and an elongated axis extending between the ends around a generally cylindrical cigar body having a central axis and first and second axially spaced portions between. which the wrapper is spirally wound at a selected wrapping angle as the cigar body moves along a wrapping path or working path generally perpendicular to the axis of the cigar body or bunch.
  • the second end of the wrapper is secured to the first portion of the body at a first wrapping position where the wrapper and bunch are brought together.
  • the first end of the wrapper extends toward the wrapping direction and the wrapper axis is generally at the wrapping angle.
  • the spacing between adjacent wrappers can be relatively small whereas in the past, the spacing of adjacent wrappers had to be sufficiently large so that the total wrapping action could take place without the cigar body engaging the tuck area of the succeeding wrapper, which area includes a spot of glue for initiating the wrapping operation.
  • the necessary spacing of bunch nests also requires substantial wrapper spacing.
  • an improved apparatus for wrapping a cigar wrapper, of the type defined above, around a cigar body is provided.
  • the improvement is provision of means for securing the trailing end of the wrapper to the cigar body at the initial wrapping station or position in the wrapping path and means for rotating the body about its axis with respect to the wrapper as the body is moving along the wrapping path so that the rotating body pulls the wrapper into a spiral pattern around the body. In this manner, the cigar body or bunch moves away from the next succeeding wrapper so that there is no interference with the glued tuck portion of the next wrapper which moves with the wrapper being wrapped.
  • a method of conveying cigar wrappers of a given length to the wrapping position of an automatic machine for wrapping the wrappers in spiral patterns and at given angles about cigar bunches The wrappers are conveyed from a storage bobbin formed from a porous web wherein successive wrappers are in parallel and are spaced in the longitudinal direction of the web a distance which is substantially less than the product of the sine of the given angle and the given length of the wrappers.
  • This method comprise the steps of transferring the wrappers in succession from the bobbin web onto a wrapper conveyor while maintaining the Spacing distance and then conveying the wrappers to the wrapping position of the automatic wrapping machine while maintaining this same spacing distance between wrappers.
  • the cigar wrappers are not respaced from the time they leave the bobbin to the time. they meet a generally cylindrical cigar bunch at the wrapping position preparatory to wrapping around a bunch.
  • the primary object of the present invention is the provision of a method and apparatus for automatically wrapping cigar wrappers spirally around cigar bunches, which method and apparatus translate the bunches faster than the wrappers and result in reduced complexity and cost of the equipment.
  • Still a further object of the present invention is the provision of a method and apparatus, as defined above, which method and apparatus incorporate a new wrapping concept for automatic wrapping machines wherein cigar bunches are wrapped toward the elongated wrappers to prevent interference between successive bunches and/or wrappers.
  • Still a further object of the present invention is the provision of a method and apparatus, as defined above, which method and apparatus can accept wrappers which are in a parallel pattern and closely spaced, even when the parallel pattern is angular and when adjacent wrappers are coextensive in a longitudinal direction and closely spaced.
  • Still a further object of the present invention is the provision of a method and apparatus, as defined above, which method and apparatus can accommodate closely spaced wrappers of the type provided on storage bobbins formed from convolutions of porous fibrous web material without respacing the wrappers between movement of the wrappers from the bobbins to the wrapping position.
  • FIGURES 1, 1A and 1B a prior concept for wrapping cigar wrappers about a cigar bunch, or body, is schematically illustrated in connection with a machine of the general type utilized in the preferred embodiment of the present invention.
  • Two cigar wrappers W1, W2 are formed into a chevron shaped compound wrapper W.
  • the two individual wrappers (W1, W2) could be integrally formed into the chevron shaped wrapper W.
  • natural tobacco leaves are used to form the two wrappers W1, W2.
  • Each wrapper has a first end 10, a second end 12 and a longitudinal axis extending between the ends and generally parallel to edge 14 of the individual wrappers.
  • end 10 is a flag or flag end, which is used to form the mouth end of a cigar.
  • End 12 is a tuck or tuck end appearing at the fire end of a completed cigar.
  • Tuck ends 12 are abutting to form chevron wrapper W, which presents wrappers W1, W2 at an angle determined generally by the angle of the abutting tuck ends. This angle is the wrapping angle for the cigar as the compound wrapper W is spirally wound around a cigar body or bunch B.
  • these bunches are formed in various machines and they generally include tobacco filler held together by an outer sealing sheet.
  • Bunches B are generally cylindrical and include contoured ends 20, 22 having a central portion 24 adapted to be contacted by tuck ends 12 of wrappers W1, W2.
  • a central axis x extends between ends 20, 22.
  • individual wrappers W1, W2 are wrapped from central portion 24 toward outer ends 20, 22 to form a dual cigar C, which is subsequently slit at center portion 24 to form two cigars C1, C2, as shown in FIGURE 6, each of which has a fire end and a mouth end.
  • means for moving bunches B in a path illustrated as circular path m, which path extends in a direction transverse to axes x of the respective bunches B.
  • Path m in the illustrated embodiment, is concentric with axis y so that compound wrappers W are wrapped around bunches B to form the dual cigars C having spaced mouth ends 30, 32. These mouth ends are covered with the flag ends of the wrappers during the wrapping operation in accordance with standard practice as described in prior United States Letters Patent 4,103,692. Wrappers W are carried to the wrapping position of path m by a continuously moving conveyor belt 40 entrained around spaced rollers 42, 44, which rollers have rotational axes generally parallel to axis y.
  • Belt 40 includes a catenary portion 46, which is formed by maintaining a fixed length of the belt between rollers 42, 44.
  • Catenary portion 46 defines an arc having a center generally concentric with axis y and defining a generally uniformly spaced wrapping gap G through which bunches B move in the path m between an initial wrapper contact position and a position where the wrapping process has been completed. This can occur at various positions in gap G according to the length of the cigar being wrapped and the wrapping angle of the individual wrappers W1, W2 with respect to bunches B and the longitudinal axis of belt 40.
  • an adhesive is generally applied adjacent a portion of tuck end 12 facing away from belt 40.
  • Bunches B are moved along path m at a velocity V1 and wrappers W are moved by belt 40 at a velocity V2.
  • the relative movement between the bunches and wrappers is such that at the end of gap G adjacent roller 42, the entrant end of the gap, bunch B coincides with.tuck ends 12 of a wrapper W.
  • an appropriate arrangement is provided in roller 42 for pushing or lifting tuck ends 12 of wrappers W1, W2 upwardly into tight adhesive relationship with central portion 24 of bunch B at the entrant end of gap G.
  • a drive means independently rotates the bunch and secured wrapper in the direction of the arrow surrounding the bunches in gap G.
  • wrappers W1, W2 are spirally wound about the bunch to which they are secured by the adhesive applied to tuck ends 12.
  • Wrapping continues until flag ends 10 are adjacent to the ends 20, 22 of bunches B.
  • the flags are wrapped into a final configuration at mouth ends 30, 32, as schematically illustrated in FIGURE 1.
  • the wrappers are held fixedly onto belt 40 by vacuum until they are progressively peeled from the belt by the wrapping action of a rotating bunch.
  • the bunch translates at a velocity V1 which is less than the translation velocity V2 of the wrappers.
  • the wrapping concept is geometrically similar to the arrangement shown in prior United States Letters Patent 4,103,692.
  • the use of the catenary belt coacting with independently driven bunches moving in a circular path is not taught by this prior United States patent.
  • the wrappers When natural tobacco leaves are used to produce wrappers W1, W2, the wrappers must be individually cut and subsequently placed into the chevron shape W, shown in FIGURE 1.
  • a compound wrapper could be cut to have this chevron shape.
  • wrappers W1, W2 When natural tobacco leaves are used to form wrappers W1, W2, they are generally provided to the wrapping machine on separate bobbins, each of which includes a number of parallel arranged wrappers captured between the convolutions of a porous web material forming the bobbin. In using this type of bobbin, the wrappers are at an angle generally corresponding to the wrapping angle r of the individual wranpers as they approach a bunch B for the wrapping operation in gap G.
  • FIGURE 1A illustrates an arrangement for producing the chevron shaped wrapper W used in the wrapping operation shown in FIGURE 1.
  • wrappers W1 illustrated as single lines in FIGURE 1A are arranged in a parallel path with a wrapping angle r defining the angle of wrappers W1 with respect to the transverse direction of the web material 50 unwound from a storage bobbin A.
  • wrappers W2 are provided on web material 52 from a second bobbin D.
  • the length of the respective wrappers W1, W2 is 1.
  • the spacing in a longitudinal direction between adjacent wrappers on bobbins A, D is the dimension a, which in practice is approximately 2.25 inches.
  • the spacing dimension or distance a is substantially less than the product of the length of the wrappers (1) and the sine of angle r.
  • the respective tuck ends and flag ends overlap each other.
  • This close spacing is required for economic storage of the wrappers on the bobbin; however, the spacing distance a is not sufficient for use in the wrapping operation as illustrated in FIGURE 1.
  • the longitudinal spacing between individual compound wrappers W, as they are introduced to the wrapping operation at gap G have a longitudinal spacing b which is substantially greater than a and near the product of the length of the wrapper, i.e. (1), and the sine of wrapping angle r.
  • Spacing b is greater than the spacing between adjacent bunches, which in practice is about 5.0 inches.
  • Wrappers W1, W2 are transferred onto a belt 40 in the chevron configuration shown in FIGURE 1A to respace the wrappers W1, W2.
  • the tuck ends and the flag ends of the adjacent wrappers do not overlap by a substantial amount in a transverse direction with respect to belt 40.
  • the wrapping operation shown in FIGURE 1 can take place. This operation is performed, as schematically shown in FIGURE 1B, by attaching a bunch B to a wrapper W at the tuck ends 12 of wrappers W1, W2 and then wrapping the bunch in gap G.
  • bunches B are equally spaced. Wrappers iq move at a faster velocity than the bunches to catch up with the bunches onto which the wrappers are being wrapped. To prevent the faster moving wrappers from reaching a bunch before a preceding bunch is completed, there is provided a spacing between two wrappers which is represented as dimension b in FIGURE 1A and dimension (c+d) in FIGURE 1B. Spacing d is between the flag end of one wrapper and the tuck end of the next adjacent wrapper. This may be varied to assure that the glued tuck ends do not engage two bunches being wrapped. Since the wrappers, in practice, are lifted to the bunches distance d can be and is negative even though shown as positive in FIGURE 1B.
  • FIGURES 2 and 2A a new wrapping concept in accordance with the present invention is illustrated wherein the various elements of FIGURE 1 are essentially the same.
  • the bunches still have a given necessary spacing.
  • wrappers W are provided on belt 40 with the flag ends 10 forward.
  • the single flag end of that wrapper would be forward of the trailing tuck end 12.
  • the wrappers extend forward at wrapping angle r with respect to the individual bunch.
  • the bunch After the wrapper has been secured to a bunch B at tuck ends 12 for the individual wrappers W1, W2, the bunch is rotated in the direction of the arrow to overrun and catch up with flag ends 10.
  • the equally spaced bunches B traveling along path m are provided with a secured wrapper and then are rotated with respect to the wrapper to cause the wrapping operation. Since the wrappers extend forward in gap G, the velocity V1 of the equally spaced bunches B is greater than velocity V2 of the wrappers secured onto the upper surface of belt 40. In this manner, the wrapping operation starts at the entrant end of gap G and the bunches move away from the incoming supply of wrappers.
  • FIGURE 2A wherein the spacing b' is the same as spacing distance a illustrated in FIGURE 1A.
  • W1, W2 These wrappers are secured onto the rotating bunches and are peeled from belt 40 as the bunches move away from the incoming wrappers at a velocity greater than the speed of the incoming wrappers.
  • the rotating bunch and wrapper form dual cigar C, as shown in FIGURE 2, which dual cigar is subsequently severed to produce two cigars C1, C2, each of which has a mouth end 30 or 32.
  • the surface speed or velocity VR of rotating bunches B is slightly greater than the surface speed necessary to wrap the wrappers around the bunches.
  • a slight amount of tension is created to stretch the wrappers W1, W2 during the wranping operation which peels the wrappers from their fixed position on belt 40 as the belt passes through gap G. Consequently, the same end product is obtained when using the new wrapping concept shown in FIGURE 2 without requiring respacing of the individual wrappers before the wrapping operation.
  • a fewer number of bunch nests are necessary to obtain the same production rate as the prior wrapping concept shown in FIGURE 1, with the same bunch or nest spacing.
  • the relative velocities V1, V2 and the rotational velocity of bunches B can be adjusted to obtain the desired rolling operation.
  • the wrappers are completely wrapped around the bunches B at a position in gap G determined by the length of the wrappers and velocity VR.
  • By rotating bunches B at a velocity greater than the actual wrapping velocity not only is tension provided to stretch the wrappers to facilitate better wranping, but also, it is assured that bunches B will not advance over the wrappers W at a translation velocity V1 which is greater than that necessary for the actual wrapping process. This therefore provides a certain amount of tolerance in the relative relationship between velocity V1, V2.
  • FIGURES 3 and 4 illustrate the relationship of the various velocities in the prior art wrapping concept illustrated in FIGURE 3 and the new wrapping concept illustrated in FIGURE 4.
  • surface velocity or wrapping velocity VR for pulling wrappers onto bunches B is controlled by the relationship between velocities V1, V2.
  • This velocity VR thus can be used to determine the rotational velocity of the various bunches B in each of the wrapping operations.
  • the wrapping velocity VR is the velocity of bunches B minus the velocity V2 of the forwardly extending wrappers W. If the wrappers were held stationary, V2 would be zero; therefore, the wrapping velocity would equal the translation velocity V1 of bunches B as they move along path m, which in the illustrated embodiments of FIGURES 1 and 2 is circular.
  • continuous flexible elongated conveyor belt 40 has an upper surface 40a with vacuum directing apertures formed into wrapper matching areas 60 having essentially the pattern of wrappers W as discussed in connection with FIGURE 2. These areas defined by vacuum apertures are arranged in a parallel pattern so that the wrappers can be captured onto surface 40a in the manner shown in FIGURES 2, 2A and 5.
  • Catenary portion 46 of belt 40 has a preselected length which remains fixed to provide a vacuum carrying surface for wrappers W which is generally concentric to axis y of path m traveled by rotating bunches B, shown best in FIGURES 2 and 6.
  • Rollers 42, 44 are driven in unison by a driven sprocket 80 rotatably mounted on frame F and driven by an appropriate motor, not shown.
  • An idler sprocket 82 combines with a sprocket 90 on roller 42 and a sprocket 92 on roller 44 to carry a chain 84 which is driven by sprocket 80.
  • an idler sprocket similar to sprocket 82 is provided on the opposite side of sprocket 80.
  • a lower fixed idler roller 100 is employed to form belt 40 with generally flat straight runs 40b, 40c, which runs are used to transfer wrappers W1, W2 from the webs 50, 52 of bobbins A, D onto the wrapper matching areas 60 of belt 40.
  • the wrappers lie in the chevron shape of the pattern defined by areas 60 spaced uniformly along belt 40.
  • a tension adjusting roller 102 is rotatably supported on shaft 104 by a lever 106 on frame F.
  • An adjusting bracket 108 adjusts the tension in belt 40.
  • roller 42 is of the type with an outer perforated surface allowing vacuum to be directed through the perforations to the outer surface. This outer surface engages belt 40 at the inner surface of the belt to draw a vacuum through the surface of roller 42 and through the openings or apertures defining the various wrapper receiving areas 60.
  • a vacuum chamber or box 109 is formed by a plurality of plates two of which are illustrated as plates 110, 112.
  • Box 109 is connected to a vacuum source so that vacuum from the box is applied to the under surface of belt 40 in the area between rollers 130, 44, as illustrated in FIGURES 5 and 6.
  • the use of vacuum boxes and other vacuum systems is well known in the cigar making art and various arrangements could be used for maintaining a vacuum onto the under surface of belt 40 in the areas necessary to capture and hold the wrappers W into the pattern shown in FIGURES 2 and 5 preparatory to and during wrapping.
  • Bobbin A having captured wrappers thereon is used to direct wrappers W1 onto the outer portion of the spaced areas 60.
  • bobbin D is used to direct wrappers W2 on the opposite side of the spaced areas 60 as belt 40 is moved along the path of belt 40 between rollers 130, 44.
  • a peeling vacuum surface roll 120 peels the web forming bobbin A from the bobbin.
  • This roller has an outer vacuum surface so that wrappers W1 are held onto the web 50 being pulled from bobbin A.
  • a vacuum transfer table 122 at run 40b has an upwardly facing generally flat vacuum surface over which web 50 carrying wrappers W1 is pulled. The speed of web 50 is controlled so that it corresponds with the speed of belt 40.
  • Bobbin A moves toward roller 120 as it decreases in size to maintain a direct transfer relationship.
  • the same basic operation is used to transfer wrappers W2 to the opposite side of areas 60 on surface 40a.
  • a peeling roll 130 having an outer vacuum surface as previously explained with respect to roll 120.
  • a vacuum transfer table 132 holds web 52 against surface 40a and moves in unison with the surface as belt 40 moves from roller 102 toward roller 100 in the straight run 40c.
  • a driven take-up spool 134 is used to pull web 52 and store the web after wrappers W2 have been removed therefrom.
  • one wrapper is deposited onto belt 40 at run 40b and another wrapper is deposited on the belt in run 40c. This forms the two wrappers into the chevron wrapper W as previously described.
  • the spacing of the wrappers on the bobbins may be slightly different from the spacing provided on belt 40. This can vary from bobbin to bobbin or in a bobbin.
  • provisions are made to drive webs 50, 52 at slightly varying speeds which do not affect transfer to belt 40. Consequently, the spacing on belt 40 and on the bobbins is substantially the same, with this qualification.
  • FIGURE 6 there is illustrated an arrangement for applying glue to the tuck ends 12 of wrappers W1, W2.
  • a glue supply 150 is transferred through a transfer roll 152 to an application roll 154. This roll applies the desired glue pattern onto the tuck ends of wrappers W1, W2 as they pass over roll 42.
  • a belt cleaning device 160 can be provided between rollers 44 and 102. This is illustrated as a jet cleaning device wherein air jets are used to direct air through belt 40 to clean the apertures forming wrapper receiving areas 60.
