Abstract
Description
- The present invention relates to a device for applying filters to cigarettes, and in particular to a device by which cigarettes and filters are joined together with gummed tipping papers.
- Conventionally, filters are applied to cigarettes by machines referred to as filter tip attachments, in a succession of steps briefly described below.
- Cigarettes are ordered in pairs, with the two cigarettes of each pair axially aligned and a filter plug double the length of a tip for one cigarette interposed between them in end-to-end contact, likewise axially aligned. The group or assembly made up of the single cigarettes and the filter plug is joined permanently by means of a gummed tipping paper wrapped around the filter plug and overlapping each of the corresponding cigarette ends by about three millimetres.
- According to prior art practice, these assembling and joining steps can be brought about on the surface of a conveying drum, onto which the aforementioned assemblies and the gummed papers are directed, in an operation whereby each assembly is rolled against a relative paper. The rolling action is induced along a passage delimited on the one hand by the drum and on the other by a fixed plate of arched profile that combines with the outer surface of the drum to create a rolling channel.
- It happens with this type of method that when given operating speeds are exceeded by the filter tip attachment, cigarettes entering the rolling channel at an angular velocity of zero, referred to their own axes, are accelerated to a relatively high speed of rotation and subjected consequently to high stresses tending to spoil the cigarettes irreparably, with the loss of tobacco particles from their ends.
- Employing a different method also embraced by the prior art, the rolling channel is created between the drum on the one hand, and on the other, a belt driven at a speed different to that of the drum and embodied usually in a flexible and resilient material. In this instance, however, the belt material tends to wear rapidly. Such a device is known from the document US-B-6 390 099.
- The object of the present invention is to provide a device for applying filters to cigarettes that will be unaffected by the drawbacks typical of prior art devices as described above.
- The stated object is realized in a device according to the present invention for applying filters to cigarettes, of which the characterizing features are recited in
claim 1 appended. - 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 portion of a filter tip attachment, viewed schematically in elevation with certain parts omitted and comprising a device for applying filters to cigarettes embodied in accordance with the present invention,;
- figure 2 shows an enlarged detail of figure 1;
- figure 3 shows a part of figure 1, viewed from above and in a section taken on III-III with certain parts omitted;
- figure 4 shows a detail of figure 2 in an enlarged and exploded view;
- figure 5 shows a detail of figure 4 in a different embodiment;
- figure 6 illustrates a portion of a filter tip attachment, viewed schematically in elevation with certain parts omitted and comprising the device of figure 1 in a different embodiment.
- Referring to figure 1 of the drawings, 1 denotes a portion of a filter tip attachment, in its entirety, comprising a device for applying filters to cigarettes, denoted 2 in its entirety. 3 denotes a
fluted drum 3 rotatable anticlockwise as viewed in figure 1, on which to advance assemblies 4 composed (as illustrated in figure 3) of twocigarettes 5 and a doublelength filter plug 6 interposed between the two cigarettes. The assemblies 4 are directed by thedrum 3 through a transfer station 7 and into thedevice 2, of which the infeed stage includes afirst conveyor 8 consisting in a roller 9, rotatable clockwise as viewed in figure 1 and furnished peripherally with a plurality of aspirating seats orgrooves 10 each serving to accommodate a respective assembly 4 together with a tippingpaper 11 cut from continuous strip by a rotary blade of conventional embodiment (not illustrated) operating in conjunction with the roller 9 at a point upstream of the transfer station 7. - Positioned in close proximity to the roller 9, downstream of the transfer station 7, is a flexible
rolling conveyor 12 that combines with the outer cylindrical surface of the roller 9 to establish arolling channel 13. The flexiblerolling conveyor 12 is looped around first and second transmission means denoted 14 and 15 of which the first, upstream, comprises a first freely revolvingreturn pulley 16 combining with theflexible conveyor 12 by which it is partly enveloped to create an infeedconveyor 17 preceding therolling channel 13, whilst the second, downstream, comprises a second power drivenreturn pulley 18 and, rigidly and concentrically associated with the pulley, a take-up roller 19 of which the periphery affords a plurality ofrecesses 20 placed to receive the assemblies 4 emerging from therolling channel 13, each with a tippingpaper 11 wrapped around thedouble filter plug 6 and thecigarettes 5 and denoted 4a. Thepulley 18 androller 19 thus constitute an outfeed and take-up conveyor 21. - In operation, the peripheral speed of the conveying roller 9 is greater than the speed of the
flexible conveyor 12 along thechannel 13, thereby inducing the rolling action. - Also shown in figure 1 is a
roller 22, indicated by phantom lines, rotatable about an axis parallel to the axis of theroller 19 by which theassemblies 4a are taken up from the conveying roller 9 and serving to feed theassemblies 4a on to further processing means not illustrated. - As discernible from the drawings, the outside face of the
flexible conveyor 12, which can be fashioned as a web or belt of resilient and flexible material, is furnished with a plurality ofrigid cladding elements 23 consisting, as illustrated in figure 5, ofmetal cleats 24 ordered one beside the next and disposed transversely to theselfsame conveyor 12. Positioned on the opposite inside face of theflexible conveyor 12, coinciding with each of thecleats 24, are fastening means 25 taking the form ofblocks 26 secured to therespective cleats 24 by clamping means 27 such as screws or bolts. - In the preferred embodiment of figure 1, it will be seen that the
rolling channel 13 is formed entirely between the cylindrical surface of the conveying roller 9 on the one hand and the corresponding branch of theflexible conveyor 12 on the other, presenting a curved profile; accordingly, thechannel 12 is furnished with retaining means and with guiding and locating means denoted 28 and 29 respectively, in their entirety, by which theconveyor 12 is made to describe a path concentric with the roller 9 and the depth of thechannel 13 maintained constant and substantially identical to the diameter of the cigarette and filter assemblies 4. - With reference in particular to figures 3 and 4, the retaining means 28 consist in a plurality of
magnetic elements 30 fashioned as discs and embedded in a pair of nonmagneticparallel bars 31 cradled by anarched member 32 consisting also of nonmagnetic material and extending parallel to therolling channel 13. - The function of the
magnetic elements 30 is to interact with thecleats 24 and with the fastening means 25 and thereby attract theflexible conveyor 12 along the length of therolling channel 13 in such a way as to maintain the correct position of theconveyor 12 relative to the conveying roller 9, as described above. - The guiding and locating
means 29 comprise a plurality of freely revolvingwheels 33 rotatable about axes parallel to the axis of the conveying roller 9 and offered in contact to the inside face of theflexible conveyor 12. - In the example of figure 3, the
wheels 33 are ordered in three races parallel to the twobars 31, which are interposed between the races ofwheels 33. Each race comprises two rows ofwheels 33 lying in parallel planes with eachwheel 33 of each row partly overlapping one or two wheels of the parallel and adjacent row, so to afford substantially continuous support to theflexible conveyor 12. In particular, the inside face of theflexible conveyor 12 affords atoothed profile 34 in mesh with corresponding teeth afforded by the first andsecond pulleys wheels 33, denoted 35, 36 and 37 respectively. - As illustrated in figures 2 and 4, the surfaces of the
cleats 24 combining to establish one face of therolling channel 13 each present areeded profile 38 that constitutes the rolling surface proper. - In addition, every
second cleat 24 of the rolling surface, in the example illustrated, is furnished along the edge located downstream in the direction followed by theconveyor 12 along thechannel 13, with a rib orlip 39 of which the function is to interact positively with each assembly 4 directed into therolling channel 13 so as to initiate the rolling step brought about along thechannel 13. - In the example of figure 5, more particularly, the adjoining edges of
successive cleats 24 present abroken outline 40 and interlock one with the next in such a way as to prevent dust or foreign matter, typically tobacco particles, from fouling the parts of theflexible conveyor 12 beneath. In this instance the aforementioned rib orlip 39 will occupy a substantially intermediate position on thecleat 24. - Moreover, and with protection likewise in mind, the
device 2 according to the invention is equipped with twoguards 41, one only of which visible in figure 1, flanking theflexible conveyor 12 on either side and occupying respective vertical planes adjacent to the tworeturn pulleys guards 41 will accommodate the drive for thelive pulley 18. - Referring to figures 1 and 2, it will be seen that the assemblies 4 enter the
rolling channel 13 spaced apart at a first pitch p1 and reach the outfeed end of thechannel 13 at a second pitch p2 shorter than the first. To the end of extracting specific and higher levels of performance from the filter tip attachment in terms of output, a further reduction in pitch is also necessary. This is obtained at the outfeed end of therolling channel 13, at the moment of transferring theassemblies 4a from the channel to the take-up roller 19: more exactly, theroller 19 is greater in diameter than thepulley 18 with which it is rigidly associated, and presents a predetermined number ofrecesses 20 spaced apart in such a manner as to shorten the distance between the advancingassemblies 4a from the aforementioned second pitch p2 to a further selected pitch p3. - In the example of figure 6, the
rolling channel 13 is created between twoflexible conveyors 12, one on either side, embodied in entirely the same way as theconveyor 12 illustrated in figure 1, thechannel 13 in this instance extending through a rectilinear path and the conveying roller 9 being replaced by aflexible conveyor 12 looped around twopulleys pulleys roller 44 presenting seats orgrooves 45 similar to the seats orgrooves 10 of the conveying roller 9, by which the assemblies 4 are taken up from thedrum 3 and transferred to therolling channel 13.
