Definitions

  • the present invention relates to an apparatus and method for the production of rods comprising a plurality of segments and finds particular application in the manufacture of combined filters or recess filters for cigarettes .
  • Cigarettes typically comprise a wrapped tobacco column that optionally is tipped with a filter.
  • the filter may be a composite multi-component filter comprising a plurality of filter rod segments.
  • the filter rod segments making up the composite filter may include different base filter materials or may comprise the same base filter material, but with alternate segments being impregnated with a particulate material.
  • Figure Ia shows a composite filter rod comprising alternating segments of cellulose acetate 2 and cellulose acetate impregnated with carbon particles 4.
  • the composite filter may comprise segments consisting of air gaps, recesses or cavities adjacent to or between the other filter rod segments making up the composite filter, which may be filled with particulate or other material.
  • Figure 2a shows a composite filter rod including segments of cellulose acetate 2, segments of cellulose acetate impregnated with carbon particles 4 and air gaps or cavities 6 interposed between neighbouring cellulose acetate segments 2.
  • the plurality of dissimilar segments 2,4,6 of the composite filter rods shown in Figures Ia and 2a are fixed in position relative to each other by wrapping the composite filter rods in a glued paper wrapper known as plug wrap.
  • Composite filters comprising a plurality of dissimilar filter rod segments including one or more air gaps or cavities are known as recess filters.
  • Composite filters that do not include any air gaps are commonly- termed combined filters. It is known to manufacture cigarettes having combined or recess filters using a two-stage double-wrap process. In the first stage, a combining device is used to form a continuous stream of aligned alternating filter rod segments of two or more different types which is then wrapped in a web of plug wrap to form a continuous filter rod. The continuous filter rod is subsequently severed at regular intervals by a cutting mechanism to yield a succession of discrete composite filter rods. In the second stage of the process a tipping machine is used to join the discrete composite filter rods to pre-wrapped tobacco columns using tipping paper, to form cigarettes.
  • the discrete composite filter rods produced in the first stage of the double-wrap process are of multiple unit length, that is they contain more than one composite filter each of which is combined with a tobacco column in order to form a cigarette.
  • a discrete composite combined filter rod produced in the first stage might contain a centrally- located two-up first filter rod segment (a first filter rod segment of double unit length) , flanked by a pair of one-up second filter rod sections.
  • the discrete composite combined filter rod would then be joined at both ends to a wrapped tobacco column to form a two-up cigarette having a two-up filter at its centre.
  • each two-up cigarette would be severed at the midpoint of the composite combined filter rod to yield two one-up filter cigarettes, each having a combined filter containing one of the second filter rod segments and one-half of the first filter rod segment.
  • the discrete recess filter rod shown in Figure 2a may be produced by forming a continuous filter rod comprising groups 8 of filter rod segments 2,4 separated by air gaps 6 and then cutting the continuous rod to the desired length. If the air gaps 6 are left unfilled, the discrete recess filter rod of Figure 2a may be cut in half centrally to produce a pair of two-up recess filter rods, each of which can then be cut in half centrally at the air gaps 6 to produce four individual one-up recess filters.
  • the discrete combined filter rod shown in Figure Ia when cut into four sections of equal length, would produce four combined filters.
  • the filtration characteristics of composite cigarette filters depend upon the length of, and in the case of recess filters also the spacing between, the filter segments therein.
  • the precise position of each cut made in the continuous filter rod relative to the plurality of aligned filter rod segments therein is, therefore, extremely important as it determines the length of the outermost or external filter rod segment of the discrete composite filter rod produced.
  • apparatus for the production of rods comprising a plurality of segments
  • the apparatus comprising: a feeder for feeding a plurality of segments along a path; a wrapper downstream of the feeder for wrapping the plurality of segments in a web of material to form a rod; a combiner operative at a location between the feeder and the wrapper for forming a stream of aligned segments from the plurality of segments and for transporting the stream of aligned segments along the path to the wrapper, and cutting means for severing the rod into a plurality of discrete rods each comprising a plurality of segments, characterised in that the combiner is adapted to maintain the alignment of segments in the stream of aligned segments as it transports the stream of aligned segments to the wrapper so that, in use, relative movement of the segments in the stream is substantially prevented over the entire length of the path from the combiner to the wrapper.
  • a method for the production of rods comprising a plurality of segments, the method comprising the steps of: feeding a plurality of segments along a path to a first position; forming a stream of aligned segments from the plurality of segments at the first position,- transporting the stream of aligned segments along the path from the first position to a second position; wrapping the stream of segments in a web of material to form a rod at the second position,- and repeatedly- severing the rod to produce a plurality of discrete rods each comprising a plurality of segments, characterised in that the method further comprises maintaining the alignment of segments in the stream of aligned segments during the transporting step so that relative movement of the segments in the stream is substantially prevented between the first and second positions.
  • the method and apparatus of the invention enable higher quality standards to be maintained with respect to variation in length of external rod segments and/or air gaps compared to known methods and apparatus for composite filter production. Furthermore, because of this reduction in relative movement of the rod segments, continuous monitoring of external rod segment length during composite filter production is unnecessary.
  • Figure Ia is a schematic representation of the filter rod segments in an exemplary combined filter rod
  • Figure Ib shows variation in length of the external filter rod segments of the exemplary combined filter rod of Figure Ia, caused, for example, by imprecise cutting of a continuous combined filter rod
  • Figure 2a is a schematic representation of the filter rod segments in an exemplary two-up recess filter rod
  • Figure 2b shows variation in length of the air gaps of the exemplary recess filter of Figure 2a, caused, for example, by movement of the filter rod segments during formation of a continuous recess filter rod
  • Figure 3 is a schematic representation of a known apparatus for producing discrete combined filter rods of the type shown in Figure Ia
  • Figure 4 is a schematic representation of a known apparatus for producing discrete recess filter rods of the type shown in Figure 2a
  • Figure 5 is a schematic representation of apparatus according to a first embodiment of the present invention for producing composite filters
  • Figure 6 is a schematic representation of apparatus according to a first embodiment of the present invention for producing composite filters
  • FIG 3 shows a known apparatus for producing discrete combined filter rods, of the type sold under model no. ND-3 by Japan Filter Technology, Ltd. (JT Group), and manufactured by Sanjo Machine Works Ltd., of Japan.
  • the known apparatus includes a combining device 10 comprising a delivery wheel 12 which arranges a plurality of dissimilar filter rod segments 2,4 onto a first endless belt conveyor 14 in a pre-selected desired configuration, such as that shown in Figure Ia.
  • the dissimilar filter rod segments 2,4 are transported to the delivery wheel 12 from two or more magazines or hoppers by a series of conveyors, not shown. As the filter rod segments 2,4 are delivered onto the first endless belt conveyor 14 they are urged against one another to form a continuous stream 16.
  • the first belt conveyor 14 transports the abutting filter rod segments 2,4 to the upper side of a continuous running paper web 18 drawn from a bobbin (not shown) .
  • the paper web 18, which has an adhesive applied to at least part of the upper side thereof, is then draped around the filter rod segments 2,4 by a garniture (not shown) to form a continuous wrapped composite combined filter rod 20.
  • the continuous paper web 18 is drawn off the bobbin and transported by a second endless belt conveyor 22 downstream through and beyond the garniture to a cutting head 24. At the cutting head 24, the continuous composite filter rod 20 is severed at regular intervals to yield a succession of discrete combined filter rods 26.
  • the cutting head 24 comprises a rotary knife 28 mounted for rotation at constant speed about an axis parallel to the longitudinal axis of the continuous composite filter rod 20.
  • the rotary knife with which the delivery wheel 12 is in phase, cuts a discrete combined filter rod upon each revolution.
  • the cutting head 24 is in phase with a filter rod segment 2,4 when the filter rod segment is fixed in position by the paper web 18.
  • any error in the position of the filter rod segment 2, 4 occurring along the path from the point where the filter rod segment 2,4 is released by the combining device 10 to the point where it is wrapped and fixed in position by the continuous paper web 18 gives rise to the same error at the cutting head 24
  • the filter rod segments 2,4 have been wrapped in the paper web 18 to form the continuous filter rod 20 they are fixed in position relative to one another.
  • the filter rod segments 2,4 can move relative to one another. Additionally, any differences in speed between the first belt conveyor 14 and the second endless belt conveyor 22 can jostle the filter rod segments 2,4 as they are transferred onto the continuous paper web 18.
  • the known apparatus shown in Figure 4 includes a combining device 30 comprising a delivery wheel 32, which deposits a plurality of filter rod segments 2,4 onto a first endless belt conveyor 34.
  • the first endless belt conveyor 34 carries the filter rod segments 2,4 downstream to a spiral spacer drum 36 that also forms part of the combining device 30, which groups the filter rod segments 2,4 in a pre-selected desired recess configuration, such as that shown in Figure 2a, by creating air gaps 6 between groups 8 of segments 2,4.
  • An endless transfer belt 38 adjacent to the spiral spacer drum 36 transports the groups 8 of filter rod segments 2,4 to the upper side of a continuous running paper web 40 drawn from a bobbin (not shown) .
  • the paper web 40 which has an adhesive applied to at least part of the upper side thereof, is then draped around the spaced groups 8 of filter rod segments 2,4 by a garniture (not shown) to form a continuous wrapped composite recess filter rod 42.
  • the continuous paper web 40 is drawn off the bobbin and transported downstream by a second endless belt conveyor 48 through and beyond the garniture to a cutting head 44 having a rotary knife 46.
  • the continuous composite filter rod 42 is severed at regular intervals into discrete recess filter rods 50 by the rotary knife 46, the spiral spacer drum 36 of the combining device 30 being operated in phase with the rotary knife 46.
  • the design of the endless transfer belt 38 which is located above the groups 8 of filter rod segments 2,4, and air gaps 6 therebetween, is such that the paper web 40 cannot be folded around the segments 2,4 and air gaps 6 while they are beneath the transfer belt 38, instead the groups 8 of filter rod segments 2,4 must exit from beneath the transfer belt 38 before being fixed in position by the folded paper web 40. Between the end of the transfer belt 38 and the point at which they are fixed in the paper web 40, the groups 8 of filter rod segments 2,4 and the filter rod segments 2,4 within each group 8 are also free to move relative to one another.
  • Relative movement of the groups 8 of filter rod segments 2,4 prior to enclosure in the paper web 40 in the apparatus of Figure 4 can not only result in the production of waste discrete recess filter rods which have external filter rod segments of different length, but also in the production of waste discrete recess filter rods which have air gaps 6 of differing length, as illustrated in Figure 2b.
  • An apparatus for producing composite filters according to a first embodiment of the present invention is shown in Figure 5. The same reference numerals are used in Figure 5 to identify parts of the apparatus according to the invention that correspond to those of the known apparatus shown in Figure 3 already described.
  • the apparatus according to the first embodiment of the invention shown in Figure 5 differs from that of known apparatus of the type shown in Figure 3 in that it additionally comprises an endless transfer belt 52 mounted above the first endless conveyor belt 14 and the second endless conveyor belt 22, between the delivery wheel 12 and the cutting head 24.
  • a plurality of evenly spaced spacers or teeth 54 are mounted on the outside of the endless transfer belt 52, the spacing between adjacent teeth 54 being equal to the length of a whole number of filter rod segments 2,4 fed onto the first endless belt conveyor 14 by the delivery wheel 12.
  • the endless transfer belt 52 is driven by a powered pulley 56 in phase with the cutting head 24.
  • the endless transfer belt 52 may be provided on its inner surface opposite the teeth 54 with in-phase pins (not shown) , which cooperate with correspondingly- spaced in-phase holes (not shown) provided in the powered pulley 56.
  • the endless transfer belt 52 and the teeth 54 may be formed from metal, rubber, plastic or other suitable material .
  • the teeth 54 on the endless transfer belt 52 separate the filter rod segments 2,4 into groups 8 of length equal to the spacing between the teeth 54, and then transfer the grouped filter rod segments 2,4 to the continuous running paper web 18.
  • the paper web 18 is then folded around the groups 8 of filter rod segments 2,4 by a known folding mechanism such as a garniture (not shown) to form the continuous composite filter rod 20, which is subsequently severed at regular intervals by the rotary knife 28 of the cutting head 24 to form discrete composite filter rods.
  • the groups 8 of filter rod segments 2,4 are held in fixed relative position by the teeth 54 of the endless transfer belt 52.
  • the distance over which the groups 8 of filter rod segments 2,4 must then be transferred before they are fixed in position by the folded paper web 18 is greatly reduced compared to the distance between the delivery wheel 12 and the point at which the filter plugs 2,4 are fixed in position in the folded paper web 18 in the known apparatus.
  • the apparatus shown in Figure 5 decreases the variation of the length of the external filter segment and, in the case of recess filters, the air gap length 6 of the discrete composite rods produced compared to known apparatus .
  • the apparatus according to a first embodiment of the invention shown in Figure 5 can be used to make both discrete combined filter rods and discrete recess filter rods (unlike known apparatus such as that shown in Figure 3) .
  • the endless transfer belt 52 and the second endless belt conveyor 22, which transports the paper web 18, are driven at the same speed.
  • the spacing 6 between the groups 8 of filter rod segments 2,4 achieved by the teeth 54 of the transfer belt 52 is thereby maintained as the grouped filter rod segments 2,4 are transferred to the paper web 18.
  • the apparatus is used for the production of discrete recess filter rods having the configuration shown in Figure 2a, the width of each tooth 54 is equal to the width of the air gap 6 in the recess filter and the spacing between adjacent teeth 54 is equal to the sum of the length of two cellulose acetate segments 2 and one cellulose acetate segment impregnated with carbon particles 4.
  • the second endless belt conveyor 22 which transports the paper web 18 is driven at a reduced speed compared to the endless transfer belt 52.
  • the spiral spacer drum 36 groups the filter rod segments 2,4 together and creates the required air gaps 6 between them and then the endless transport belt 38 moves the grouped filter rod segments 2,4 towards the paper web 40.
  • transfer of the groups 8 of filter rod segments 2,4 between the spiral spacer drum 36 and the transfer belt 38 introduces an additional source of error in the relative positioning of the filter rod segments 2,4 in the continuous recess filter rod 42 produced.
  • the endless transfer belt 52 with teeth 54 performs the function of both the spiral spacer drum 36 and the transfer belt 38 of the known apparatus of Figure 4 and so avoids the introduction of this additional source of error.
  • the endless transfer belt 52 of the apparatus of Figure 5 may also be mounted for pivotal movement about powered pulley 56 thereby allowing for easier cleaning beneath the transfer belt 52, compared to the transfer belt 38 of the known apparatus of Figure 4, should filter rod segments 2,4 become jammed beneath the transfer belt 52 during production.
  • An apparatus for producing composite filters according to a second embodiment of the present invention is shown in Figure 6. The same reference numerals are used in Figure 6 to identify parts of the apparatus according to the second embodiment of the invention which correspond to those of the known apparatus already described.
  • the structure of the apparatus according to the second embodiment of the invention shown in Figure 6 differs from that of known apparatus such as that shown in Figure 3 in that it additionally comprises a transfer device 58 mounted above the first endless conveyor belt 14 and the second endless conveyor belt 22, between the delivery wheel 12 and the cutting head 24.
  • the transfer device 58 repetitively delivers filter rod segments 2,4 from the delivery wheel 12 to the continuous running paper web 18 at a location along the second endless conveyor belt 22 just upstream of a garniture or other known folding mechanism (not shown) .
