Description

The present invention relates to an apparatus for making a filter rod for use in the manufacture of smoking articles such as filter cigarettes.

Filtered cigarettes typically include a rod of tobacco cut filler surrounded by a paper wrapper and a cylindrical filter that is aligned end-to-end with the wrapped tobacco rod and attached to it by chipping paper. .. Filters generally consist of one or more plugs made of fibrous filter material. One suitable fibrous filter material is cellulose acetate tow, which is often treated with a plasticizer such as triacetin. One or more plugs are surrounded by a paper material commonly referred to as a "plug wrap".

Manufacture of filter rods from continuous fiber filter tow is a process of moving the filter toe generally in the longitudinal direction through a continuous processing step for arranging the tow fibers, and the tow is collected, compressed and given a predetermined shape ( It comprises the step of applying a plasticizer and / or other additives to the fiber before it is formed into a substantially cylindrical rod, etc.). Further, the manufacturing process includes wrapping the fiber tow rod with a plug wrap to produce a packaged filter rod.

For this purpose, filter rod manufacturers include packaging stations for receiving rod-shaped fiber tows from forming stations and for wrapping rod-shaped fiber tows with filter paper to form continuous filter rods. Is done. The packaging station is an endless conveyor belt (eg, provided as a garniture tape) configured to travel in a predetermined direction along an endless path, and a filter at the first part of the path. It is provided with a supply device for supplying the paper ribbon onto the belt conveyor. In addition, the packaging station comprises a guide element that gradually converts the conveyor into a tube at the second portion of the path downstream of the first path portion by moving the lateral ends of the belt towards each other. Manufacturers of this type of filter rod are described, for example, in US 47685626.

More specifically, the conveyor generally comprises a belt looped around two return rollers. One tributary of the belt runs slidably along the longitudinal grooves provided within the guide element or ganiture. The grooves are continuously different between the inlet and outlet ends of the guide and have a substantially cylindrical cross section at the outlet end. The belt that slides in the groove constitutes a ganiture tape, which guides the filter paper ribbon traveling from the first path portion and wraps around the fiber toe rod in the second path portion. .. Therefore, at the packaging station, the filter paper ribbon is wrapped around a rod-shaped fiber toe so that the edges of the filter paper ribbon overlap.

In addition, filter rod manufacturers apply the appropriate adhesive to one or both side ends of the filter paper ribbon so that they are bonded together when one or both side ends of the filter paper ribbon overlap. Includes adhesive means. The adhesive may be applied onto the packaging web material in the applicator area along the packaging ganiture, or, as an alternative, upstream of where the packaging web material enters the packaging station's ganiture.

As an example, a heat-activating adhesive may be applied to one or both side edges of the filter paper ribbon, and the filter rod manufacturer may further provide a heat source for activating the adhesive. It is placed along the ganiture.

In addition, filter rod manufacturers generally include additional means of cooling the adhesive in order to cure it rapidly. In particular, filter rod manufacturers are well known to include cooling bars coupled with endless belt conveyors to allow them to operate, located along the path of the packaging web material downstream of the heat source. One such cooling bar is generally configured to have a temperature of about −5 ° C to about 6 ° C during use. This ensures that as the packaged rod moves along the cooling bar, the adhesive cures and a sealed longitudinal seam is formed.

The packaged filter rod thus manufactured can then be cut into segments of predetermined length to obtain a filter plug element. In particular, filter manufacturers have placed cutting assemblies downstream of the cooling bar to cut continuously packaged filter rods leaving the packaging station into filter rod portions with lengths corresponding to multiple filter plug elements. Prepare with. These filter rod portions may then be transferred to a filter combiner or chipping machine for attachment to the tobacco rod. For this purpose, the filter rod maker of exit station is provided with a plurality of flutes which are adapted to receive a filter rod portion leaving the packaging station (groove (flute)), for conveying the filter rod portion to another task unit Equipped with a moving drum.

For certain applications, it may be preferable to use a stiffer, thicker packaging web material, such as to give the filter greater rigidity. However, this may make it difficult to form a filter rod with a low ellipticity. In addition, increased friction along the packaging web material path between the rigid packaging web material and the filter rod manufacturer's parts generates more heat, affecting the cooling bar sealing efficiency. sell.

At the same time, the overlapping lateral edges of the packaging web material wrapped around the rod-shaped fiber toe increase due to the increased inherent tendency of the stiff, thicker packaging web material to elastically return to its original flat state. A larger amount of adhesive is needed for proper sealing. However, this can have the undesired effect of accumulating excess adhesive on the surface of the moving drum that receives the packaged filter rod portion at the exit of the packaging station. Because of this, filter rod manufacturers can often have to be stopped, which undesirably increases machine downtime.

Therefore, it is desirable to provide an apparatus for making a filter rod for use in the manufacture of smoking articles so that the shortcomings identified above can be effectively addressed. In particular, machine downtime is significantly reduced, while at the same time ensuring that the filter rods obtained by the device meet the manufacturing requirements required in, for example, seal quality, ellipticity, visual impact and other aspects. It is desirable to provide a device for

According to one aspect of the invention, there is provided an apparatus for making a filter rod for use in the manufacture of smoking articles. The device comprises an operating station for receiving the filter plug material and the packaging web material, and for forming the packaged filter rod from the filter plug material and the packaging web material. The device also comprises at least one cutter blade for cutting the packaged filter rod into elongated rod segments. In addition, the device comprises a moving device on the outer surface of the drum that includes a rotating drum with multiple flutes through the gap, the flutes configured and arranged to receive elongated rod segments as the drum rotates. .. The drum further comprises stopping means at one end of each flute, which is positioned when the elongated filter rod is received within the flute. The stopping means has a first diameter (D1) and a flute axis (F) between the first end where the pin is attached to the drum frame and the second end opposite the first end. It has a pin with a cylindrical body that extends along. Further, the pin includes an adjacent portion extending along the axis (F) from the second end of the cylindrical body, the adjacent portion having a second diameter (D2) smaller than the first diameter (D1). And presents a substantially flat surface for adjoining the end of the elongated filter rod.

楕円率＝（ｂ−ａ）． The term "ellipticity" is used herein to describe the shape of the transverse portion of the filter rod and to describe the degree of deviation from the perfect circle. In this case, the ellipticity can be expressed as a length, the mathematical definition of which is given below.

Ellipticity = (ba).

To determine the ellipticity of a segment of the filter rod, look at one end along the major axis of the filter rod. For example, the filter rod may be placed so that its end is on a transparent table so that the image of the end of the filter rod is recorded by a suitable imaging device located under the transparent table. To. The dimension "a" is taken to be the minimum outer diameter of the segment at its downstream end, and the dimension "b" is taken to be the maximum outer diameter of the segment at its downstream end. The process is repeated for a total of 10 filter rods with the same design, and the average of 10 ellipticity measurements is recorded as the ellipticity of the filter rods for that design.

In contrast to well-known equipment, filter rod manufacturers are provided with an improved moving device for feeding newly formed filter rod segments. The moving device includes a rotating drum with a plurality of flutes across the gap on the outer surface of the drum, where the flutes are configured and arranged to receive elongated rod segments as the drum rotates. The drum is equipped with stopping means at one end of each flute, where an elongated filter rod is adjacent when received within the flute. The stopping means include a pin that presents a substantially flat surface for adjoining the end of the elongated filter rod. The pin is the end that contacts the elongated filter rod during use and includes a portion that has a smaller diameter than the cylindrical body of the pin.

By providing a stopping means that presents a small surface area for direct contact with the freshly formed filter rod segment, the potential for adhesive to accumulate on the stopping means is advantageously significantly reduced. Although not bound by theory, it is understood that the adjacent ends of the pins make contact with the radial center of the filter rod segment, where it is generally expected to be adhesive-free. There is. At the same time, a small gap is left between the stopping means and the periphery of the filter rod segment, which is the portion of the filter rod segment where the adhesive is most likely to be present, which is the adhesive. This is because the agent is applied to form a seal between the overlapping longitudinal lateral ends of the packaging web material.

Therefore, the number and frequency of outages of the filter rod manufacturer is significantly reduced, which is advantageous in terms of overall machine downtime. Thus, filter rod manufacturers according to the invention are particularly useful in the manufacture of filter rods, including stiffer thick wrappers, or in larger quantities to securely and safely seal the packaging web material around the filter plug material. It is especially useful whenever the adhesive is needed. As will be apparent from the following description, in some preferred embodiments, further advantageous improvements may be obtained in relation to the properties of the filter rod, such as seal quality, ellipticity, visual effects.

The apparatus according to the invention comprises an operating station for receiving filter plug material and packaging web material, and for forming a packaged filter rod from the filter plug material and packaging web material. In addition, the device comprises at least one cutter blade for cutting the packaged filter rod into elongated rod segments. In addition, the device comprises a moving device for feeding the newly formed elongated rod segment. The moving device includes a rotating drum with a plurality of flutes across the gap on the outer surface of the drum, the flutes being configured and arranged to receive elongated rod segments as the drum rotates. The drum further comprises stopping means at one end of each flute, which is positioned when the elongated filter rod is received within the flute. The stopping means has a first diameter (D1) and a flute axis (F) between the first end where the pin is attached to the drum frame and the second end opposite the first end. It has a pin with a cylindrical body that extends along. Further, the pin includes an adjacent portion extending along the axis (F) from the second end of the cylindrical body, the adjacent portion having a second diameter (D2) smaller than the first diameter (D1). And presents a substantially flat surface for adjoining the end of the elongated filter rod. The adjacent portion preferably has a cylindrical shape.

The second diameter (D2) is preferably less than about 80 percent of the first diameter (D1). Yet, or otherwise, the second diameter is at least about 50 percent of the first diameter (D1). These values are advantageous because the wide enough annular portion around the filter rod segment does not adjoin the flat surface of the stopping means, thereby minimizing the possibility of adhesive getting on the drum. .. In some particularly preferred embodiments, the second diameter (D2) is about 75 percent of the first diameter. As an example, the first diameter (D1) may be 8 mm and the second diameter (D2) may be 6 mm.

The length (L) of the adjacent portion measured along the axis (F) of the flute is preferably at least about 0.5 mm. Yet or otherwise, the length (L) of the adjacent portion measured along the axis (F) of the flute is less than about 2 mm. These values are advantageous because a sufficiently wide axial gap is thus left between the periphery of the filter rod segment and the flat surface of the stopping means. This also helps to minimize the possibility of the adhesive getting on the drum. In some particularly preferred embodiments, the length (L) of the adjacent portion measured along the axis (F) of the flute is about 1 mm.

The operating station of the device is generally operably coupled to an endless belt conveyor and configured to receive filter plug material and packaging web material, and in the first and second major axis directions of the packaging web material. It comprises a ganiture configured to wrap the packaging web material around the filter plug material so that the ends of the wrapping overlap to form a packaged filter rod. In addition, the operating station comprises an applicator that supplies a heat-activated adhesive to seal the overlapping first and second longitudinal ends of the packaging web material. The heat-activated adhesive can be applied to one or both longitudinal lateral ends of the packaging web material.

The operating station is further equipped with a heat source for activating the adhesive, which is located along the ganiture. More specifically, the ganiture is adapted to supply heat to the overlapping first and second longitudinal ends of the packaging web material, while an endless conveyor belt that slides through the ganiture. It is preferred to be operably coupled to a heating bar that supports the lateral end of the. The heating bar is preferably provided with a groove having an arcuate contour for at least partially receiving the sealed packaged filter rod.

The heating bar contains a pair of heating bar ridges, and as the belt slides along the ganiture, the support surface of the ridges is an endless belt conveyor in a V-shaped arrangement (when viewed in cross section). Each heating bar ridge defines the boundaries of the groove of the heating bar on one side and presents the supporting surface on the other side so that it is adapted to support the lateral end of the axis. Is even more preferable.

In fact, the heating bar is arranged facing the upper surface of the belt in which the groove of the heating bar travels through the groove of the ganiture. As the belt travels along the ganiture, the longitudinal lateral ends of the belt slide against the (outer) support surface of the heating bar ridge, and the sealed packaged filter rod is on the upper side of the belt. Substantially enclosed within the volume contained between the surface and the surface of the groove of the heating bar. This is advantageous in that it prevents the belt from moving away from the correct center position within the ganiture. Moreover, this favorably favors the formation of filters with low ellipticity.

The heated bar ridges have a substantially triangular cross section, and the supporting surface is such that the longitudinal lateral ends of the belt form an angle of at least about 30 degrees between them (V-shaped arrangement). Is preferably tilted. It is more preferred that the support surface be tilted so that the longitudinal lateral ends of the belt form an angle of at least about 45 degrees between them. In some preferred embodiments, the support surface is tilted so that the longitudinal lateral ends of the belt form an angle of about 60 degrees between them.

In addition, the operating station preferably comprises a cooling bar operably and thermally coupled to the ganiture and endless belt conveyors to cool and cure the adhesive. The cooling bar is located downstream of the heat source. In a preferred embodiment, the cooling bar is located just downstream of the heating bar and can be mounted on the same bracket.

The cooling bar has a longitudinal groove extending between the cooling bar inlet and the cooling bar outlet, and is fitted within the groove of the ganiture so that the groove is adapted to receive the packaged filter rod at least partially. It faces the upper surface of the advancing belt and is placed with a groove in the longitudinal direction. At the cooling bar inlet, the cross section of the groove is preferably substantially semi-circular.

In fact, the cooling bar is placed slightly away from the ganiture so that the belt passage is defined between the ganiture and the cooling bar. The grooves may be laterally bounded by lateral ridges that present their respective outer adjacent surfaces adapted to coordinate with the longitudinal lateral ends of the belt traveling between the cooling bar and the ganiture. Preferably, the surface area of the cross section of the groove is preferably reduced between the cooling bar inlet and the cooling bar outlet.

Therefore, as the belt travels along the ganiture, the distance between the opposing surfaces of the belt's longitudinal lateral ends increases as the belt reaches the cooling bar inlet and also the belt's longitudinal lateral. The end comes into contact with the lateral ridge of the cooling bar groove. This is advantageous because the belt is thus restrained from sliding against the rest of the cooling bar and thus the cooling bar is not heated by the friction of the belt against the cooling bar. On the other hand, the packaged filter rod is maintained between the upper surface of the belt and the surface of the cooling bar groove, along with a heat-activating adhesive that seals the overlapping lateral ends of the packaging web material. Thus, the adhesive previously heated by the heat source provided between the overlapping longitudinal lateral ends of the packaging web material is cooled and rapid curing of the adhesive can be achieved.

In some preferred embodiments, the device is operably coupled to the ganiture, placed at the downstream end of the ganiture, and at the overlapping first and second longitudinal ends of the packaging web material. Along the way, it is further equipped with compression means adapted to work with the packaged filter rod. The compression means is configured and arranged to apply a compressive load substantially along the radial direction of the packaged filter rod to the packaged filter rod. This is especially advantageous when rigid or thick packaging web materials are used. The reason is that the provision of such compression means can effectively counter the inherent tendency of the rolled packaging web material to move away from the completely cylindrical arrangement around the filter plug material. , This peculiar tendency is understood to be one of the main causes of ellipse.

It is preferable that the compression means includes a linking portion having a substantially spherical shape. This is fairly smooth between the compression means and the outer surface of the packaged filter rod so that the surface finish of the packaged filter rod is not significantly affected while at the same time reducing the ellipticity. It is advantageous in that cooperation is provided. Therefore, the overall visual impact of the packaged filter rod is advantageously improved.

The present invention will be further described, albeit only as an example, with reference to the accompanying drawings below.

The adjacent portion 118 has a second diameter D2 of about 6 mm. The adjoining portion 118 presents a substantially planar surface 120 for adjoining the ends of the elongated filter rod segment 104. In the embodiments illustrated in FIGS. 1-3, the adjacent portion 118 has a cylindrical shape and has a length L measured along an axis (F) of about 1 mm.

FIG. 4 shows a schematic cross-sectional view of a ganiture 200 and a heating bar 202 of an operating station of a preferred embodiment of the apparatus according to the invention. The ganiture 200 is coupled with the endless belt conveyor 204 so that it can be operated. Further, the ganiture 200 is configured to receive the filter plug material and the packaging web material, and the first and second longitudinal ends of the packaging web material overlap to form a packaged filter rod. As such, the packaging web material is configured to be wrapped around the filter plug material. The ganiture 200 is further coupled operably with a heating bar 202 to activate the adhesive applied to one or both of the longitudinal lateral ends of the packaging web material in the upstream position. Supply heat. At the same time, the heating bar supports the longitudinal lateral ends of the endless belt 204 slidably propagating within the ganiture 200. The heating bar 202 comprises a groove 206 with an arcuate contour for at least partially receiving the heat-sealed packaged filter rod. As illustrated in FIG. 4, the heating bar 202 comprises a pair of heating bar ridges 208, 210, each of which heating bar ridges 208, 210 define the boundary of the heating bar groove 206 on one side and on the other side. Supporting surfaces 212, 214 are presented. The support surfaces 212, 214 of the heating bar ridges 208, 210 are adapted to support the lateral ends of the belt in a V-shaped arrangement as the belt slides along the ganiture 200. Ru. The volume defined by the upper surface of the belt 204 and the groove surface of the heating bar groove 206 substantially surrounds the sealed packaged filter rod. In use, this advantageously prevents the belt 204 from moving away from the exact center position and also favors the formation of a low ellipticity packaged filter rod. In the embodiment of FIG. 4, the hopper ridges 208, 210 have a substantially triangular cross section, and the support surfaces 212, 214 have a lateral end of the belt approximately 60 degrees between them. It is tilted to form an angle α.

The operating station of the device according to the invention is a ganiture and endless belt to cool and cure the adhesive supplied to the longitudinal lateral ends of the packaging web material for sealing around the filter plug material. It is preferred to further include a cooling bar that is operable and thermally coupled to the conveyor. The cooling bar is located just downstream of the heating bar. Details of such a cooling bar 300 are shown in FIG. The cooling bar 300 includes a longitudinal groove 302 extending between the cooling bar inlet 304 and the cooling bar outlet 306. The cooling bar groove 302 is adapted to receive the packaged filter rod at least partially. In use, the cooling bar 300 is placed with the longitudinal groove 302 facing the upper surface of the belt traveling through the groove of the ganiture so that the passage of the belt is defined between the ganiture and the cooling bar. It is placed a little away from (not shown). At the cooling bar inlet 304, the cross section of the cooling bar groove 302 is substantially semi-circular. The cooling bar groove 302 is laterally provided by lateral ridges 306, 308 presenting their respective outer adjacent surfaces adapted to coordinate with the longitudinal lateral ends of the belt traveling between the cooling bar 300 and the ganiture. The boundary is set in. The surface area of the cross section of the groove 302 is reduced between the cooling bar inlet 304 and the cooling bar outlet 306. Thus, as the belt travels along the ganiture, the distance between the opposing surfaces of the belt's longitudinal lateral ends increases as the belt reaches the cooling bar inlet 304, and the belt's longitudinal side. The side end comes into contact with the lateral ridges 306 and 308 of the cooling bar 300. Therefore, the belt is advantageously restrained from sliding against the rest of the cooling bar 300 downstream of the cooling bar inlet 304, or at least the coordination between the belt and the cooling bar 300 is significantly restricted. Will be done. This is advantageous in that the cooling bar 300 is not significantly heated by the friction between the belt and the cooling bar 300.

The compression means is advantageous in that the rigid or thick packaging web material moves away from the completely cylindrical arrangement around the filter plug material within the newly formed packaged filter rod. Effectively countering trends, this unique tendency is understood to be one of the main causes of ellipses. Further, due to the spherical shape, the compression means 400 provides a smooth coordination between the compression means 400 and the outer surface of the packaged filter rod. Therefore, the surface finish of the packaged filter rod is substantially unaffected, and thus the overall visual effect of the packaged filter rod is advantageously improved.
