Abstract
Description
- The present invention relates to a device for the treatment of filter material utilized in tobacco products, typically cigarettes.
- Conventionally, the manufacture of filter tips for cigarettes, be it with simple or composite type filter plugs, involves processing a filter material consisting for instance in a ribbon or stream of fibrous cellulose acetate tow, which is stretched initially, then impregnated with plasticizers, and finally gathered around a central axis to form a continuous rod, which is enveloped in a paper plugwrap.
- The impregnating step takes place as the stretched ribbon is directed through special treatment devices designed to invest the advancing material with a flow of plasticizer, typically triacetin, which at the normal operating temperature and pressure of the treatment devices will remain in the liquid state. Accordingly, the ribbon is sprayed with a flow of liquid consisting in particles of predetermined quantity and size, in such a manner that a prescribed quantity of the triacetin will be absorbed.
- Prior art type devices used to implement the step in question comprise a container, or bath, holding a predetermined quantity of triacetin, and a revolving brush partly immersed in the triacetin, which when set in rotation at a normal operating speed will project a flow of liquid droplets toward a ribbon of cellulose acetate advancing in close proximity.
- Other prior art devices make use of spray nozzles positioned below the ribbon being impregnated, by which a flow of triacetin is directed upwards at the underside of the advancing ribbon.
- While serviceable, both of the aforementioned devices present a major drawback, associated with the difficulty of regulating the quantity of triacetin delivered in such a way as to maintain a uniform distribution of the plasticizer over the filter material.
- In effect, it will be appreciated that the quantity cannot be regulated either by varying the flow rate of the plasticizer, in the case of the nozzles, or by increasing the speed of rotation in the case of the brush, as this would produce a change in the size of the triacetin particles delivered ultimately to the target.
- Consequently, the flow of plasticizer directed at the filter material undergoes a modification, and the impregnation is rendered non-uniform.
- Accordingly, the object of the present invention is to provide a device for the treatment of filter material used in tobacco products, such as will be unaffected by the drawbacks mentioned above.
- In particular, the object of the invention is to provide a device for treating filter material used in tobacco products, such as will allow of regulating the quantity of triacetin delivered, and maintaining a uniform distribution of the plasticizer over the ribbon or stream of filter material.
- A further object of the invention is to provide a device for the treatment of filter material used in tobacco products, having the merits of simplicity in construction and a low cost of realization.
- The stated objects are achieved in a device according to the present invention for the treatment of filter material used in tobacco products, of which the features are recited in the appended claims.
- The invention will now be described in detail, by way of example, with the aid of the accompanying drawings, in which:
- figure 1 illustrates a cigarette filter making machine, equipped with a device according to the present invention;
- figure 2 is a perspective view of the device according to the present invention, shown with certain parts cut away better to reveal others;
- figures 3a, 3b and 3c illustrate the device in plan from above, shown in a succession of operating positions;
- figure 4 is a side view of the device according to the invention.
- With reference to the accompanying drawings,
numeral 1 denotes a device, in its entirety, for treating filter material used in tobacco products, in accordance with the present invention. - The
device 1 is applicable tomachines 100 used in the manufacture of filters for tobacco products, and for cigarettes in particular, substantially of the type illustrated in figure 1. -
Such machines 100 comprise amagazine 101 holding filter material, and more exactly containing one ormore bales 102 of filter material, of which one only is illustrated in figure 1. Two respectivefibrous tows 103 are drawn from thebales 102 and directed by means of conventional guide devices toward a station at which the filter material is processed. - In detail, the filter material passes through a processing station comprising at least one
blower device 104 of conventional type, producing a flow of air by which thefibrous tows 103 are expanded and formed into continuous streams "F" of given width. In a preferred embodiment, the processing station will comprise threesuch blower devices 104, stationed along a feed line "L" as illustrated in figure 1. - The aforementioned processing station further comprises a
device 1 according to the present invention for treating the filter material, located downstream of theblower devices 104, by which the continuous streams "F" of fibrous tow are taken up and plasticized through impregnation with a suitable plasticizer fluid. - The treated streams "F" advance thereafter toward a
transfer device 105 by which the continuous tows are taken up on the infeed side, gathered each about a respective centre axis, and caused to emerge on the outfeed side in the form ofropes 106, each advancing above acorresponding web 107 of previously gummed paper, and finally wrapped in thegummed webs 107 to fashionrespective rods 108 of filter material. - The
rods 108 obtained in this way are fed toward adevice 109 that will test their density, thence to acutter head 110 by which theselfsame rods 108 are divided transversely into respective successions of plugs, not illustrated. - The
device 1 according to the present invention for treating filter material used in tobacco products, indicated in the central part of figure 1, will now be described in detail. - In particular, the
device 1 comprises feed means (conventional in embodiment and therefore not illustrated in detail) by which the continuous stream "F" of fibrous tow is caused to advance along a predetermined path denoted "A". - The
device 1 further comprises at least onedelivery unit 3 from which a plasticizer fluid "P", such as triacetin, is directed at asurface 2 of the stream "F". - The
delivery unit 3 is placed below the stream "F" of fibrous tow, so as to project the fluid "P" upwardly at the stream "F" as it advances in a longitudinal feed direction denoted "A" in figure 2. - Also forming part of the
device 1 are control means 4 serving to regulate the quantity of fluid "P" directed at the stream "F" of fibrous tow, acting on thedelivery unit 3 in such a way as to adjust its position relative to the path followed by the stream "F". - Such control means 4 comprise at least one
table element 5, also a plurality ofspray nozzles 6 carried by the table element and forming part of thedelivery unit 3, by which the aforementioned fluid "P" is projected at the stream "F" of fibrous tow as an array of respective liquid cones. - As illustrated by way of example in figures 3a, 3b and 3c, the
table element 5 is capable of movement between a first operating position, in which thenozzles 6 lie entirely within the transverse dimensional limits of the stream "F" (figure 3c), as defined by twolongitudinal edges 7 of the selfsame stream "F", and at least a second operating position in which at least certain of thenozzles 6 are located outside the selfsame transverse dimensional limits (figures 3a and 3b). - In particular, the
table element 5 presents asurface 8 directed toward theaforementioned surface 2 of the stream "F", and referable to a predominating longitudinal dimension that extends transversely to the longitudinal feed direction "A". - To advantage, the
multiple spray nozzles 6 carried by thetable element 5 are arranged in close order along the full length of thesurface 8 presented by the element. - With reference in particular to figure 3a, it will be seen that the
table element 5, when occupying the second position, extends at right angles to the longitudinal feed direction "A". In this situation, respectiveopposite ends 9 of thesurface 8 are located outside the transverse dimensional limits of the stream "F", with the result that no fluid "P" is directed at the stream "F" from thenozzles 6 carried by these same twoends 9. - Figure 3c shows the
table element 5 occupying the first operating position, in which all of thenozzles 6 are located within the transverse dimensional limits of the stream "F", so that a greater quantity of fluid "P" is directed at the filter material. - Figure 3b shows the
table element 5 occupying an intermediate operating position, in which more of thenozzles 6 are located within the transverse dimensional limits of the stream "F" than is the case in the second position. - Significantly, the movement of the
table element 5 is effected by inducing rotation about arespective fulcrum point 10, in such a way as to position theends 9 internally or externally of thelongitudinal edges 7 of the stream "F". - In particular, the control means 4 include motion-inducing means 11 by which the
table element 5 is made to rotate between the first and second position, pivoting on thefulcrum point 10, the fulcrum being located on a median line of thetable element 5. - As illustrated to better advantage in figure 2 and in figure 4, such motion-inducing means 11 present a substantially
vertical shaft 12 of which afirst end 12a is fixed to thetable element 5 at thefulcrum point 10, and asecond end 12b opposite to thefirst end 12a is associated with arespective motor 13. - To advantage, as illustrated in figure 4, the
device 1 comprises acollection tank 14 positioned with an open cavity facing toward the advancing stream "F" of fibrous tow. - The
tank 14 functions as achannel 15 in which to catch the fluid "P" delivered by thenozzles 6 when not absorbed by the stream "F". - The
device 1 further comprises a pair ofapron elements 16, each interposed between oneend 9 of thesurface 8 and alongitudinal edge 7 of the stream "F". - More exactly, each
apron element 16 is associated with a relative side wall of thetank 14 and located below the level of the stream "F", presenting onerespective edge 16a in alignment with the correspondinglongitudinal edge 7. - In addition, the
underside 17 of eachapron element 16 is directed toward thenozzles 6 located at onerespective end 9 of thetable element 5 when in the second operating position. - Thus, when the
surface 8 of thetable element 5 is positioned with the twoends 9 beyond the transverse dimensional limits of the stream "F" of fibrous tow, the fluid "P" released from thenozzles 6 not directed at the stream "F" is intercepted by theunderside 17 of eachapron element 16 and will drop into thechannel 15. Accordingly, the fluid "P" is recovered and returned to the delivery system for reuse. - Advantageously, according to the invention, the quantity of fluid "P" directed at the stream "F" of fibrous tow is regulated by inducing motion in the
table element 5. - In effect, by positioning the table 5, it becomes possible to include a greater or lesser number of
nozzles 6 within the transverse dimensional limits of the stream "F", and at the same time increase or reduce the overlap between areas targeted by the single spray cones. Accordingly, the quantity of fluid "P" directed at the stream "F" can be regulated without altering the flow rate, thus maintaining a uniform distribution of the fluid "P" along and across the stream. - It will be observed, moreover, that the
device 1 is structurally simple, as also is the step of regulating the flow of plasticizer fluid, accomplished simply by rotating thetable element 5.
