Description

"METHOD AND APPARATUS FOR THE APPLICATION OF ADHESIVE TO THE ROLE OF CIGARETTES AND THE PAPER AND CIGARETTES PRODUCED WITH THEM" The present invention relates to the manufacture of cigarettes and more particularly to a method and an apparatus for applying uniformly and precisely one adhe sive _^ anchor wrapping paper used in the fabrica¬ tion snuff rods for smoking articles such as cigarettes, and the cigarette wrapper paper and one produced thereby.

In the technique of making cigarettes, there is a tendency for small particles or strips of tobacco to fall out of the loose ends of the tobacco rods, during handling, packing and shipping associated with the production of cigarettes, and during - handling by retail sellers and distributors, as well as by consumers. In fact, it has been measured that the loss of tobacco resulting from such loose ends is greater than 16% of the average based on weight. One method to minimize loose ends - requires the introduction of an additional amount of tobacco into the flow of cigarette filling at predetermined spacing intervals along the length - length of the growing tobacco rod. An adhesive is applied to a longitudinal edge of the cigarette wrapping paper in which the tobacco fill flow is deposited, the cigarette paper is then wrapped around the tobacco fill with the edge to which the cigarette has been applied. adhesive overlapping the opposite edge of paper and containing the tobacco filling in a continuous rod-like shape. The resulting increased density - of the tobacco filling located in those predetermined spaced intervals coincides with the ends of the tobacco rods after cutting them into individual tobacco rods during cigarette production. Each one of the ends of the tobacco rod on both sides of the cuts has a higher packing density of tobacco known as a "dense end." Such late ends tend to reduce unwanted tobacco loss during tobacco rod handling during manufacture and subsequent handling of cigarettes.

While this provides an acceptable solution - to the problem of "loose ends", the value of this solution is however compromised from the point of view of cost, due to the requirement of additional tobacco to create the dense end. It is also known that a dense end of a tobacco rod in which the tobacco is highly compacted will restrict the flow rate of tobacco smoke through the cigarette when used in the manner for which it is intended, increasing with this undesirably the shooting resistance encountered by the smoker at the beginning of consumption and that gives the smoker the perception of a poor or inconsistent product.

Several other solutions have been carried out to reduce the loose ends of the tobacco rods.- The UK Patent Application No. 2 243 983, for example, discloses a method and apparatus for training of a cigarette to which an adhesive is applied in strips by a printing wheel along a longitudinal edge of the wrapping paper, and in longitudinal places spaced them across the entire transverse dimension - of the paper from that edge. The cigarette paper is then wrapped around the tobacco filling flow deposited on it and the longitudinal adhesive strip is fixed on the opposite edge of the paper. Each adhesive-cross strip forms an adhesive ring around the entire inner circumference of the formed tobacco rod. The tobacco rod is then cut transversely at the center point of each transverse adhesive strip and at the central points between the strips, to form rods of tobacco with an annular adhesive band on the inner surface of the free end of each tobacco rod, which avoids "loose ends".

According to an alternative form of the apparatus, the adhesive is applied to the cigarette paper by means of an air jet that is directed against a screen that carries an adhesive liquid to cause the adhesive to be thrown onto the cigarette paper. A disc mounted on an axis that rotates at a predetermined speed, in synchronization with the advancing cigarette paper, includes a window through which the air jet is directed at those time intervals _^ spond to run with the rotation speed of the disk. An important problem of this embodiment is an excess of spraying, inherent in the operation of the apparatus, thereby limiting the precise and uniform application of the adhesive to the cigarette paper. Another problem is the relatively limited speed of tobacco rod production, because of a relatively low rotation speed of the disc, since that speed is necessarily limited to allow the air jet to pass through the window of the disc to collide with the screen that carries the adhesive and to project the adhesive on the cigarette paper.

US Patents Nos. 4,715,388 and 4,785,831, disclose other methods and apparatus for minimizing the loose ends of cigarettes, for example, by incorporating into the filling of tobacco a hygroscopic powder that becomes sticky when absorbed humidity, or by the application of a foaming adhesive to the free ends of cigarettes after their manufacture. The latter method and apparatus suffer from similar deficiencies to the other apparatus of the previous solution, since it is not capable of operating at high production rates, compared to modern cigarette manufacturing machinery. The first method creates the position 1 ability to undesirably stain the cigarette paper with the dust particles that come into contact - with that paper.

In view of the shortcomings of the methods and apparatus indicated 5 times, it is desirable to provide a method and - an apparatus to minimize the loose ends of - cigarettes, and that is capable of operating at speeds - of machinery production Modern manufacturing of - cigarettes. In particular, it would be desirable to provide a method

0 d and an apparatus to minimize the loose ends of cigarettes, which is capable of being used during the process of manufacturing cigarettes with existing machines, capable of production speeds of 8000 cigarettes or more per minute .

5 Accordingly, the basic objective of the present invention is to provide a method and apparatus for minimizing the loose ends of smoking articles, such as cigarettes, at production rates of 8000 cigarettes or more. per minute in each manufacturing line. 0 That objective is fulfilled in accordance with the present invention, by providing a method and apparatus for the precise and rapid application of an anchoring adhesive to a cigarette paper that advances just before deposition. of the tobacco filling on paper. Another object of the present invention is to provide - a method and an apparatus for the precise and uniform application of a spray pattern, previously determined, of an anchoring adhesive on a transverse location - selected from a continuous roll of cigarette paper, - 0 in advance during the manufacture of tobacco rods. Another objective of the present invention is to de-spray an adhesive anchor pattern on a roll of continuous cigarette paper, in advance during the manufacture of tobacco rods, such that the area and the Adhesive location reduce loose ends reduce 'also minimizing the amount of adhesive needed to do so.

Another object of the present invention is also to provide an alternative method to minimize loose ends, to allow less dense packing of tobacco rods.

Another objective of the present invention is to provide an apparatus for minimizing loose ends, by precisely and uniformly applying an anchoring adhesive to a roll of continuous cigarette paper in advance, so that said apparatus is universally adapted. table to the cigarette manufacturing apparatus commonly known and used in the art.

Another object of the invention to provide a paper - d _e cigarette wrapper with an adhesive anchor - - applied to it to reduce to the minimum loose ends. Another object of the invention is to provide cigarettes with reduced loose ends and having a substantially uniform density from side to side. The present invention consists of a method and an apparatus for the uniform and precise application of a predetermined small amount of adhesive, anchoring in a predetermined spray pattern to a continuous roll of cigarette paper, in the advance during the manufacture of Tobacco rods for cigarettes.

In accordance with the aspects of the invention, the apparatus comprises an adhesive application system that can be portable and back-installable to existing cigarette machines. The system comprises a high speed spray applicator, which is mounted in a cigarette producer, before an accessory adjacent to the path of the continuous roll of cigarette paper. An - remote-located adhesive pump and a regulated compressed air source supply adhesive to the spray applicator from a reservoir under the control of a programmable trolador. A current encoder located after the accessory locates the linear velocity of the advancing tobacco rod and introduces this data to the programmable controller. After the linear speed has been located by the encoder, the tobacco rod advances further towards a cutting blade with a reciprocating motion, to cut the advancing tobacco rod. The operation of the cutting blade generates a trigger signal that is introduced into the programmable controller, so that the signal of the cutting blade controls the total timing of the operation of the spray applicator system. The cutting blade can be adjusted for di. in front of the tobacco rods to be cut. The trigger signal generated by the operation of the cutting blade is received and processed by means of the programmable controller, which commands the operation of the spray adhesive sprayer applicator under pressure. The pump delivers a supply of liquid adhesive to a spray nozzle located opposite the continuous roll of cigarette paper in advance. The speed of the adhesive pump is controlled by the cigarette producer, and a servo feedback and solenoid system provides a controlled flow of adhesive liquid to the needle valve activator, which is atomized by air Compressed from the air source. The system re¬ tro-supply solenoid regulated pressure bom¬ ba within a range of about 5 psi to approxi mately 18 psi _^ is also contemplated that the adhesive - spray chosen to be a carrier for a product It gives flavor, to improve the taste of the first puff or lighting of the cigarette.

The cigarette paper advances around a previous term and three pinwheels fixed on the cigarette producer. Keep advancing cigarette paper at - along a horizontal path between the two forming windlasses, in which the paper is held opposite to the spray nozzle, oriented vertically, and - which uniformly and accurately applies a predetermined amount of adhesive anchor, in a predetermined spray pattern, to cigarette paper.

The spray nozzle is mounted for adjustment in the vertical and horizontal planes, also allowing the adjustment of a vertical distance between a waste tip: g of the spray nozzle and cigarette paper, as necessary to achieve a desired spray pattern of the anchoring adhesive, that is to increase or reduce the width of the adhesive strip in relation to the width of the paper. Preferably, the adhesive strip has a width substantially less than the width of the paper and is spaced from both edges of the paper to avoid an excess of spraying on the surrounding components.

According to the aspects of the method of the invention, the controller is programmed with specific spacing patterns, obtained by starting points and programming stop points in relation to the desired length of the adhesive pattern and the selected length of the formed tobacco rod required for a particular cigarette of a predetermined length. Small discrete amounts of the anchoring adhesive are periodically discharged under control of the controller through the needle valve and sprayed on the continuous roll of cigarette pee at scheduled time intervals in advance, resulting in the arrangement of strips elongated adjectives spaced, of a desired length. If the programmed spacing pattern does not occur at the place of _^ in relation to the cutting blade, a compensation factor is introduced in the controller to adjust - the position of the cut to fork the elongated adhesive strip into two strips of equal substantial length. Precise placement of the adhesive on the paper, followed by a uniform bifurcation of the strip on each cutting line, equals the amount of anchoring adhesive on each end of tobacco rod, to minimize and evenly the amount of loose endings. Preliminary test data has shown that losses due to cigarette producer rejections - can be reduced from 30% to 70% depending on the sensitivity of the rejection adjustment. It has also been proven that 20% to 40% less loose tobacco results when the standard Borgwaldt loose end test is carried out on cigarettes made in accordance with the present invention. The method and apparatus of the present invention - can be used with cigarette producers producing 8000 or more cigarettes per minute in each line, which - is substantially higher than the yield rate of - - approximately 3000 cigarettes per minute believed to be - They are possible using the UK device 2,243,983 - indicated above.

Figure 5 is a schematic diagram of the main components of the adhesive application system of the invention.

Referring in detail to the drawings, in which the same parts are designated with the same reference numbers throughout the description, a perspective view of the adhesive application system of the invention is illustrated in Figure 1, which It is generally designated with the reference number (10). In Figure 1 the system (10) is shown only what is necessary for a complete understanding of the present invention, but it is understood that other conventional components of the cigarette producer are necessary for the operation of said system

(10) Depending on the type of cigarette-producing machine to which the aforementioned system (10) is applied, minor modifications to the existing parts of the machine may be necessary to accommodate the preconditioned apparatus, without altering the essence of the invention.

The adhesive application system (10) of the present invention is used in conjunction with a conventional cement producer (12), which has a tobacco pouring apparatus (14), to deposit a pre quantity or weight ¬ determined of tobacco on a continuous strip or roll (16) of cigarette paper moving in the direction of travel indicated by arrow A. Cigarette paper - -

(16) advances through a paper guide indicated by the reference number (18), and passes through an adhesive applicator indicated by the reference number (20). After spraying an anchoring adhesive onto the cigarette paper (16) by the applicator (20) in the manner which will be described in more detail below, a tobacco filler spill is deposited on the paper (16) in the tobacco spill apparatus (14). It is then applied adhesive to an edge of the paper (16) by means of an applicator - of conventional adhesive (22), after which the paper is wrapped around the tobacco in the accessory (23), with its overlapping edges and the Edge adhesive is cured or dried to form a continuous rod of tobacco (R), which - will later be cut into cigarettes of a predetermined length, or cut into lengths and assembled with - filters to form complete filter cigarettes.

A stream cipher (24), located cont _j L nuación of the accessory (23) detects the linear speed of the rod snuff (R) in advance, and inputs this data to a programmable controller (26) through line - - (28). The programmable controller (26) is preferably a Vansco No. 99-07-44 controller model manufactured by - - Vansco of South El Monte, California 91733, and the encoder (24) is preferably a speed detector model dad nδ 99-07-45 also made by Vansco. The encoder - (24) includes a rotary detection wheel (30) (figure 5), which is located in connection with the producer's drive belt. The wheel (30) detects the linear speed of the rod on a 1: 1 basis, so that in a revolution of the detector wheel (30), the encoder produces a predetermined number of electronic pulses, for example 1200 pulses , corresponding to a specific length of the tobacco rod. As will be described in more detail below the exact linear mediation of the advancing tobacco rod by the current encoder (24) allows a precise and uniform application of the anchoring adhesive on the cigarette paper (16).

After detecting the linear speed per part of the encoder (24), the tobacco rod (R) advances to a cutting blade (32), which rotates in an individual direction. - n -

each by the arrow (B), to transverally cut the tobacco rod (R) that advances along a cutting path (33) of the cutting blade (32). The operation of - the cutting blade (32), generates a trigger signal that is introduced into the programmable controller (26) through - the line (34). That operation of the cutting blade - (32) of the cigarette producer (12), can be adjusted in a conventional manner to cut the tobacco rod (R) into different predetermined lengths of the rod, to make filter cigarettes and Unfiltered.

The trigger signal generated by the operation of the cutting blade (32) is received and processed by the - controller (26), which controls the operation of a pump - for the spraying apparatus of the anchoring adhesive (40) . - Some components of the spraying apparatus (40) are mounted on a transportable wheel carriage (42). The apparatus - - (40) also requires a regulated compressed air source and a pump (46) for the delivery of a supply of liquid adhesive from a reservoir (48) through a first conduit (50) and through from a second conduit (52) to the spray applicator (20). The pump speed (46) - is controlled by the controller and a servo solenoid and feedback system (53), to provide a corroded flow of liquid adhesive to a needle-valve activator (54) in a spray nozzle (55) (figure 2) outside the applicator (20). The adhesive is vaporized in the spray nozzle (54) by the compressed air from the air source (44) (figure 5), which flows to the applicator (20) through a third conduit (56). The solenoid feedback system regulates the pump pressure within the range of approximately 5 psi to approximately 18 psim although a higher or lower supply pressure can be used. A suitable liquid adhesive includes any modified starch or dextrin adhesive, copolymer emulsions of ethylene vinyl acetate or other - Suitable adhesive commercially available. It is also contemplated that the selected adhesive can function as a carrier of a flavoring product to improve the taste of the first puff or cigarette lighting. With reference to figures 2 and 3, the structure of the paper guide (18) and the adhesive applicator (20) is described. The cigarette paper (16) advances around a previous tensioner (60), comprising an arm (61) with a roller (62) mounted at its end and tangent to a propulsion wheel (64) that rotates in the Direction of the - arrow. The paper (16) then passes over windlasses - (66), (68) and (70) mounted for rotation in a support plate (72) that is fixed to the cigarette producer (12) by bolts (73). According to this form, the paper of garment (16) advances along a horizontal path between the turnstiles (68) and (70), between which the lower part of the paper passes in relation opposite to the spray nozzle (55) oriented vertically. The valve activator (54) activates the spray nozzle (55), to uniformly and accurately apply a predetermined amount of anchoring adhesive, in a predetermined spray pattern, of the spray nozzle ( 55) to the continuous roll of cigarette paper (16) in advance. A preferred spray nozzle (55) is a mini A-2074 model spray applicator nozzle, made by Vansco, and a preferred valve actuator (54), is a high speed activator model No. 40-40- 10 also manufactured by Vansco. From the paper guide (18), the paper (16) advances upwards through a guide with groove (75) towards the accessory (23) (figure 2).

Figure 4 shows the application of two adhesive anchor patches (80), longitudinally aligned along the center line of the cigarette paper (16), and an adhesive strip (82) that applied to a bo_r of longitudinal cigarette paper (16). The patches (80) are applied with the spray nozzle (55) and the strip (82) is applied with the conventional applicator (22) (figure 1). It is understood that the image of the cigarette paper - - (16) of Figure 4 represents the structure of the paper in a flat condition after the application of the ad hesiva strip (82) along the edge of the paper (16) by the - - adhesive applicator (22). In the more conventional cigarette producer, the longitudinal adhesive strip (82) is applied to the edge of the paper at or around the time when the paper is formed on the tubular tobacco rod with the edges in an overlapping relationship.

The spray nozzle (55) is mounted on a console (76) that is fixed in an adjustable manner by a pair of threaded bolts (78), which are projected through corresponding vertical grooves (79) formed in the console (76), to securely secure the console (76) to - the support plate (72). The console (76) is adjustable in a vertical plane in the direction of the arrow (C), thereby allowing the adjustment of the vertical distance (D) between the tip of the spray nozzle (55) and the Horizontal plane of cigarette paper (16), passing between the turnstiles (68) and (70). Such adjustment is provided to achieve a desired spray pattern of the anchoring adhesive, that is to increase or reduce the width of the elongated strips (80) in the wide dimension (E) indicated in Figure 4. Preferably , the discharge tip of the spray nozzle (55) is adjusted at a vertical distance of approximately 6mm from the cigarette paper (16), with a preferential range of 3-1Omm and a more preferential range 4-8mm from the paper (16). At a vertical distance of approximately 6mm the wide dimension (E) of the adhesive patches (80) is approximately 5-6mm. This is the width - preferred for a cigarette paper having a width - (H) of approximately 27mm (Figure 4).

The spray nozzle (55) is also supported in a housing (82), mounted for adjustment in a horizontal plane forward and away from the plate (72) and the console (76), by a rotary screw (84) threadedly connected with a follower (86) that It has an internal thread diameter (87). The perpendicular or transverse position of the spray nozzle (55) in relation to the longitudinal axis of advancing cigarette paper (16) is adjusted by turning the spline button (88) located at the end of the screw (84). Correspondingly, the housing (82) and the spray nozzle (55) with the valve activator - (54), are adjustable in the direction of the arrow (F) (Figure 3). Although Figure 4 shows the resulting adhesive adhesive patches (80) that extend along the center or middle line of the cigarette paper (16), - it is understood that the valve activator (54) and the spray nozzle (55) can be adjusted vertically and / or horizontally, to cause an adhesive anchor patch - of a desired transverse width (E) to be sprayed in a transverse position relative to the longitudinal axis - of the paper-contained roll of cigarettes in advance (16). The operation of the system (10) is illustrated in - figures 4 and 5, together with the programming of the patterns - of the length and spacing of the anchoring adhesive in the direction of advance of the cigarette paper (16). More particularly, the controller (26) is programmed with - a specific adhesive length and spacing patterns obtained by programming the start and stop points in relation to the subsequent cutting ends - of the rod of tobacco and the total - desired length of the tobacco rod required for a cigarette of a particular length. With particular reference to Figure 4 and according to the operation of the system (10), discrete amounts of the anchoring adhesive are discharged from the spray nozzle (55) under the control - of the controller (26) and the valve activator (54) on the cigarette paper (16) in advance, for a preprogrammed period of time and at preprogrammed intervals. This operation results in the deposition of elongated adhesive strips (80) evenly distributed having a length indicated by the arrow (G) and a dimension (J) between the centers of the adjacent strips (80). - The dimension (J) is equal to the length of two tobacco rods cut from a length (K). Preferably, the elongate strips (80) have a longitudinal dimension in the range of approximately 24-40mm and a preferred dinal length dimension of approximately 32mm from the leading edge to the trailing edge.

Typically, the placement or pattern of the adhesive packs (80) would be used to make filter cigarettes, where the filters would be subjected subsequently to the tobacco rods of a length in the cutting line (33) a half way between adhesive patches (80). - In the case of unfiltered cigarettes, the additional adhesive patches (81) (indicated in the drawing of hidden lines in Figure 4) are preferably arranged in the cutting lines (33) between each adjacent pair of patches - - (80) so that the two sides of the tobacco rods - of a length (K) will be treated with adhesive. This pattern will minimize loose ends on both sides of the unfiltered cigarette. The adhesive patches (81) could also be used for filter cigarettes if desired, for example to avoid the loose ends of the tobacco varnish during processing before fixing a filter to one side of each rod of tobacco.

The operation of the system (10) begins with the reception of a signal from the cutting blade (32), which is transmitted to the controller (26) through the line (34), - sending an electrical signal from the controller (26), through lines (36) and (38), to activate the pump (46) and the valve activator (54). Simultaneously, - a signal is sent by the controller (26) to another solenoid (not indicated), to activate the source of compressed air (44) necessary to atomize the anchoring adhesive in the spray nozzle (55). If the programmed place of the elongated strips (80) or (80 and 81) is not in the desired position in relation to the cutting blade (32), a compensation factor is introduced into the controller - (26), to adjust the position of the elongated strips (80), or (80 and 81), so that the cutting blade (32) cuts - the tobacco rod (R) along each cutting line (33).

Precision placement of adhesi patches. you (80) or (80 and 81), on the belt (16), one in relation - with the other and at the cutting intervals, results in a uniform bifurcation of the cutting lines (33), in such a way that the quantity and distribution of the adhesive - anchor at each cutting end is equal, thereby minimizing the loose ends of the cut tobacco rods and eliminating the need to increase the density of the tobacco rod at their free ends.

In accordance with the present invention, as it has been discovered, it is not necessary to provide a complete annular band of adhesive on the inner circumference of the cigarette-paper at the free end of the tobacco rod, to substantially minimize loose ends . It has been found that a strip of only about 5-6 mm of the circumference, or about 20% or less of a total circumference of approximately 27mm, is - substantially equivalent to providing a complete annular band, especially when the length of the Adhesive band is 2-3 times its width. Such elongated adhesive strip, - relatively narrow, is particularly advantageous - that substantially eliminates any overspray - q _Ue inevitably would result if applied to edge to edge of the paper.
