The present invention generally relates to tobacco rod formation in the manufacture of smoking articles, including cigar manufacturing and, in particular, to a method and apparatus for the formation of machine-made tobacco rods for use in the production of cigars.
In the manufacture of machine-made cigars, it is essential that tobacco be utilized as efficiently as possible due to its relatively high cost. In modern cigar manufacturing, it is also desirable to closely control the quantity of tobacco contained in each cigar, so as to provide a cigar that is considered well filled and is well filled on a consistent basis.
Tobacco utilization in the manufacture of machine-made cigars may be problematic with respect to certain tobacco blends. Machine-made cigars produced from pipe-tobacco blends have achieved wide acceptance in the market place. However, pipe-tobacco blends may have a degree of tackiness imparted thereto by the flavorants and other additives employed to enhance smoking enjoyment. The tacky, tobacco borne materials tend to stick to and accumulate along, guides, plows, garniture folding surfaces and the like of tobacco rod forming machines and other tobacco handling apparatus. Machines for making tobacco rods from pipe-tobacco blends are often modified to increase the clearances between parts (such as between a belt and a guide adjacent the belt) to accommodate the tacky pipe-tobacco blends, increasing the likelihood that the tobacco will escape and be utilized less efficiently, with greater tobacco waste.
There is a need for an improved method and apparatus for the manufacture of tobacco products, including machine-made cigars from tacky tobaccos, which will provide satisfactory cigars and be efficient in the use of tobacco.

As can be the case in the manufacture of certain machine-made smoking articles, such as cigars, the tobacco may comprise a tacky material combined therewith prior to or during rod formation, such as by way of addition of flavorants and other additives. Examples of suitable types of tobaccos that may be used in the manufacture of machine-made cigars include, but are not limited to, flue-cured tobacco, Burley tobacco, Maryland tobacco, Oriental tobacco, rare tobacco, specialty tobacco, reconstituted tobacco, blends thereof and the like. Optionally, the tobacco may be pasteurized. In the alternative, the tobacco material may be fermented.
Suitable flavorants and aromas include, but are not limited to, any natural or synthetic flavor or aroma, such as tobacco, smoke, menthol, mint (such as peppermint and spearmint), chocolate, licorice, citrus and other fruit flavors, gamma octalactone, vanillin, ethyl vanillin, breath freshener flavors, spice flavors such as cinnamon, methyl salicylate, linalool, bergamot oil, geranium oil, lemon oil, and ginger oil.

Humectants can also be added to the tobacco material to help maintain the moisture levels. Examples of humectants that can be used with the tobacco include glycerol and propylene glycol. It is noted that the humectants can also be provided for a preservative effect, as the water activity of the product can be decreased with inclusion of a humectant, thus reducing opportunity for growth of micro-organisms. Additionally, humectants can be used to provide a higher moisture feel to a drier tobacco component.
In one form, the tobacco used in the manufacture of machine-made cigars employing the apparatus and methods disclosed herein is a pipe tobacco blend having a degree of tackiness imparted thereto.

As shown, the apparatus 10 includes a tobacco feed section 12, an in-feed section 14 and a finishing section 16. The tobacco feed section 12 may include at least one conveyer (not shown) for receiving a stream of tobacco from a source of tobacco. Tobacco feed section 12 may also include at least one electromagnetic vibrator (not shown) for providing the stream of tobacco in a substantially uniform format. Suitable electromagnetic vibrators 18 are available from Eriez Corporation of Erie, Pa. and possess the ability provide for the relatively high speed feeding of light, bulky materials.
In one form, the in-feed section 12 may be constructed from existing equipment, such as an in-feed section of an AMF cigarette making machine. The finishing section 16 may also be constructed from existing equipment, such as a Molins Mk 8 or Mk 9 machine, available from Molins PLC of Milton Keynes, UK.

As the column of tobacco proceeds into the finishing section 16 it is drawn through a rod-forming arrangement 40, which includes a tongue 58. The rod-forming arrangement 40 is configured and arranged to fold the binder and the wrapper web 30 and 34, respectively, longitudinally around the tobacco column and, in one form, employs a first garniture (or short folder) 64 and a second (or finishing folder) 66 for folding the wrapper web about the compressed tobacco column so as to form a continuous rod of tobacco suitable for use in the production of smoking articles, such as cigars, the wrapper web provided from a source of wrapper material. An adhesive, which may be an adhesive such as PVA, is applied by an adhesive applicator 59 to one lap edge of the wrapper web 34, and seals the lap joint by applying heat, by at least one heater 67 to set the adhesive.
To further demonstrate the folding or rolling operation, reference is made to
A continuous rod is thus produced and is carried by the garniture tube belt 42 through an optional air bearing arrangement (not shown). The rod then emerges from the garniture tube belt 42 and may pass through a weight scanner (not shown) and then through a diameter gauge (not shown) before being cut into discrete rod lengths by a cutter 68.
When forming tobacco rods, particularly when the tobacco is of the type similar to that frequently marketed as pipe tobacco, the tobacco tends to accumulate on the machine surfaces. In manufacturing operations, to mitigate the problems associated with this accumulation, opposing parts were designed to have greater clearances, greater than a nominal clearance. The greater clearances permitted the escape of tobacco during machine operation.
It has been discovered that the use of a semi-crystalline thermoplastic material, which also has a desired degree of wear resistance, to fabricate parts of the rod making apparatus that come into contact with tobacco, reduces or eliminates tobacco accumulation on machine parts having surfaces that come into contact with tobacco, permitting closer clearances to be employed between many of the parts, including clearances 25, as shown in
As may be appreciated, closer clearances enable improved tobacco utilization, since the escape of tobacco is reduced or minimized during the rod making operation. In operation, the resultant rod making machine is cleaner, faster, more consistent, more flexible, and more efficient than prior designs. As may be appreciated, such advantages can lead to the production of higher quality product.
Poly(aryl ether ketone)s are generally synthesized by an aromatic nucleophilic substitution reaction of activated aryl dihalides with aromatic diphenolates in a dipolar aprotic solvent, or by electrophilic (Friedel-Crafts) acylation of aryl ethers. PEEK polymers are obtained by step-growth polymerization by the dialkylation of bisphenolate salts. Typically 4,4′-difluorobenzophenone is reacted with a disodium salt of hydroquinone, which is generated in situ by deprotonation with sodium carbonate. The reaction is conducted at around 300° C. in polar aprotic solvents—such as diphenylsulphone, and, in one form, is shown below.
PEEK possesses excellent mechanical and chemical resistance properties that are retained to high temperatures. The Young's modulus is 3.6 GPa and its tensile strength is 90 to 100 MPa. PEEK has a glass transition temperature at around 143° C. (289° F.) and melts around 343° C. (662° F.). It is highly resistant to thermal degradation as well as attack by both organic and aqueous environments. It is attacked by halogens and strong Bronsted and Lewis acids as well as some halogenated compounds and aromatic hydrocarbons at high temperatures.
PEEK also possesses outstanding wear resistance, low moisture absorption and has good dimensional stability. PEEK is an excellent machining material, exhibiting the characteristics of a soft brass. Additionally, PEEK carries a UL 94-V-0 flammability rating and is FDA approved for food contact. PEEK is available from a number of suppliers, including Victrex USA, Inc. of West Conshohocken, Pa. 19428. When measured by ASTM D3702-94(2009), “Standard Test Method for Wear Rate and Coefficient of Friction of Materials in Self-Lubricating Rubbing Contact Using a Thrust Washer Testing Machine,” PEEK frequently exhibits wear factors as high as about 100 in3 min/ft·lbs·hr., or about 150 in3 min/ft·lbs·hr., or about 200 in3 min/ft·lbs·hr., or about 300 in3 min/ft·lbs·hr., or about 375 in3 min/ft·lbs·hr., depending on its formulation.
In one form, the squeeze bars 60 and 62 are formed of a material comprising PEEK. In another from, the tongue 58 is also formed of a material comprising PEEK. In still another form, the transition piece 56 is also formed of a material comprising PEEK. In still yet another form, the short folder 64 and, optionally, the second folder 66 for folding a wrapper material around the compressed tobacco so as to form a continuous rod of tobacco are formed of a material comprising PEEK. With respect to the foregoing, PEEK may be utilized along surfaces that come into contact with tobacco.
It is contemplated that additional components of the apparatus 10 may be formed from PEEK. For example, the conveyor belt guide 70, which the lower conveyor belt 24 rides along, may also be formed from PEEK. In addition, it is contemplated that the transition piece 56 (see
In one form, the apparatus 10 employs a programmable logic controller (PLC unit) to control the formation of machine-made tobacco rods. Suitable PLC units are available from a number of sources, including Allen-Bradley, a division of Rockwell Automation of Milwaukee, Wis. The vibratory waterfall feeder 20 is fed by a metering belt (not shown) which may be adjusted proportionally to the rod-making speed by signals received by the PLC unit. In one form, there is a sensor provided to monitor rod-making speed and the PLC unit is programmed to dynamically adjust the metering belt in response to changes in rod-making speed.
Various signals, which may include a signal representing the rod diameter, an indication of the tobacco temperature obtained from a temperature sensor that may be located in a tobacco hopper, or in the chamber near the trimmer are fed to the PLC unit. Suitable rod diameter gauges may be as described in U.S. Pat. No. 2,952,262, the contents of which are hereby incorporated by reference in their entirety.
In operation, a tobacco column is carried on the gravity conveyor 24 and drawn by the lower and upper belts 24 and 50, respectively. between the squeeze bars 60 and 62 to the garniture tube belt 42. A signal indicative of the firmness of the finished rod may be used to control the trimmer height preferably after correction to compensate for moisture variations so that the trimmer is controlled in response to the “dry firmness.” A control motor may drive the trimmer up and down around an average trimmer height Havg, in response to control signals from the microprocessor 66. The actual height H of the trimmer, determined by a trimmer position sensor (not shown), is fed to the PLC unit to provide a signal corresponding to the actual resistance of the part of the filler column that remains after trimming.
From the data received, the PLC unit may calculate characteristics of the finished product and display such information on a display unit. PLC unit and display unit may be housed within a cabinet, which may also include a control panel, the combination of which forms a control system. The control panel may provide the ability to control various functions, including the heaters, glue applicator, machine start-up, system power, etc. Suitable control systems may be obtained from Jewett Automation of Richmond, Va. In one form, control system is a Jewett Automation Model Q75.
Alternatively, or in addition, information can be fed to a central management control system either for instant display or for storage, or for both.
Additionally details concerning process controls and control schemes useful in the operation and control of apparatus 10 are provided in U.S. Pat. No. 4,567,752, the contents of which are hereby incorporated by reference in their entirety.
Testing was conducted to evaluate the productivity over an extended period of time for an apparatus designed in accordance with the teachings herein. The focus of the evaluation was on machine runtime v. downtime, material and filler waste and non-conforming product. Performance measurements with respect to productivity included target rod weight, speed in rods per minute, production in terms of trays of product and machine interference downtime. (Machine interference downtime is downtime not directly attributable to the machine, or inherent in the operation of the machine.)
Performance measurements with respect to waste and non-conforming product included loose wrapper and binder, loose filler (collected from the production floor), long-ends (i.e., rod-outs) and wrapper and binder cores.
The data collection procedure employed was as follows. For productivity measurements, data were collected for nine shifts on the inventive rod maker and five shifts on the control maker by the operator who, at the beginning of the shift recorded target rod weight, speed in rods per minute, time to the nearest minute when the machine is first up and running. Each machine interference downtime occurrence was recorded by recording the time that the machine went down and recording the time that the machine was back up and running. An explanation was provided for each downtime occurrence. At the end of the shift, the following were also recorded: time to the nearest minute when the machine was taken down and the total production in trays.
For waste and non-conforming product, data were collected for nine shifts on the inventive rod maker and five shifts on the control maker. Different types of waste (i.e., racker rods, loose wrapper/binder, loose filler, and long-ends) were collected in separate boxes during the shift. At the end of the shift, the boxes were weighed individually, and the weight (in pounds) of each box, minus the tare weight, was recorded. When the operator removed the wrapper and binder cores during bobbin changes, the cores were saved and individually weighed on a scale and data recorded.
Upon completion of data collection, the data were summarized and statistical analyses performed to calculate productivity, waste, and non-conforming product measures. Determined were production utilization efficiency, production per available minute, material waste rates, filler waste rates, non-conforming product rejection rates.
The evaluation was conducted with the inventive rod maker and control rod maker producing product to a target rod weight of 3,300 mg. The inventive rod maker was running at a speed of 1,100 cigars per minute while the control rod maker was operating at a speed of 800 cigars per minute. All productivity calculations assume 3,800 rods per tray. Utilization is equal to runtime divided by total time. Efficiency is equal to runtime divided by available time and available time is equal to total time minus machine interference downtime.
The inventive rod maker produced an average of 101 trays per shift during the evaluation. This compared to an estimated average of 55 or fewer trays per shift produced by the control rod maker.
The inventive rod maker was operated during the evaluation under controlled conditions by an excellent operator; there was no downtime for shift meetings, brand changeovers, scheduled cleanups, preventive maintenance, etc. The productivity measures above may be adjusted to reflect these sources of downtime by estimating the additional downtime, subtracting it from the available time, and applying the production per available minute to the adjusted available time.
Notable causes of machine downtime during the evaluation include: tongue adjustments, a blade break and change, and cleaning of cutter gears.
As specified above, waste data were collected from the inventive rod maker and a control rod maker. During the evaluation, waste was collected from each rod maker and weighed by category. Waste rates for each category were calculated relative to the number of rods produced by the rod makers. The waste rate results are presented below:
As indicated above, the use of PEEK to form critical components has been found to permit the establishment of tighter part-to-part clearances, minimizing the escape of tobacco during the rod formation operation. Thus, through material selection and the setting of proper clearances, together with the integration of a PLC control system, improved performance was achieved. Forming critical components from PEEK yields components that do not collect tobacco on their surfaces during rod-making operations, since tobacco does not readily adhere to PEEK-produced components.
While the present inventions have been described in connection with a number of exemplary forms, and implementations, the present inventions are not so limited, but rather cover various modifications, and equivalent arrangements, which fall within the purview of the present claims. For example, it is contemplated that the subject matter disclosed herein would have utility in the formation of any wrapped or formed body produced from a tacky shredded material, such as shredded herbal material, pouches of tacky shredded material, moist snuff or the like.
