Definitions

  • This invention relates to a machine and a method for making plug wraps for the tobacco industry.
  • the invention addresses the production of plug wraps, also known as connecting strips or patches, from a continuous web.
  • the invention can be advantageously applied in machines for making articles for the tobacco industry and, in particular, in "filter tip attachment” machines, to make plug wraps from a continuous web, to connect the filter to the active portion of each article.
  • articles for the tobacco industry is used generally to denote rod-shaped articles comprising an active portion which releases a substance to be inhaled, a filter and a plug wrap used to join the active portion and the filter to each other.
  • the article may be a traditional cigarette which can be smoked by burning the end of the active portion, or it may be an electronic cigarette which may be inhaled by heating but not burning the active portion.
  • the active portion may comprise at least one tobacco segment of traditional type or it may be an aerosol-generating element, that is, a product containing a heat-not-burn type tobacco.
  • the tobacco may be, for example, pre-treated, reconstituted, homogenised or cast-leaf tobacco.
  • the connecting strip is wrapped at least partly around the segments according to known rolling methods.
  • pairs of segments are disposed in axially aligned fashion and a double length filter is interposed between them; the set thus formed is connected by a previously gummed plug wrap and then cut in half to make two articles.
  • the plug wraps are obtained from a continuous web of gummed material which is fed along a predetermined feed path to a cutting device which divides the continuous web into plug wraps or strips of predetermined length.
  • the cutting device may, for example, comprise two counter-rotating, tangent rollers whose axes of rotation are parallel and one of which is a suction roller adapted to entrain the continuous web. Also, at least one of the rollers is provided with blades which are angularly equispaced on its peripheral surface in order to cut the web into individual plug wraps.
  • the suction roller After cutting, the suction roller also holds the plug wraps on its surface so they can be transferred, one after the other, to the point where they meet the aforementioned sets consisting of the double filters and pairs of segments.
  • the webs used may thus be provided with additional elements located at a predetermined spacing along the length of the webs themselves.
  • the Applicant has, however, found some critical aspects in the production of plug wraps comprising such elements.
  • the plug wraps obtained are not cut uniformly and the additional elements are not centred/correctly disposed on the surface of each plug wrap (or they may even be incomplete because they have been truncated) and this may give rise to difficulties in the subsequent step of rolling the plug wraps round the segments.
  • each transverse cut made on the web must be repeated as precisely as possible at the same position between every pair of consecutive additional elements.
  • EP0766928A1 a device for the production of filter tip bands for ventilated cigarettes, according to which a continuous strip is advanced along a pre-set feed path.
  • An adhesive substance is applied to the strip using a gumming device, defining on the strip itself a periodic succession of gummed areas alternated with non-gummed areas and the strip is out using a cutting device according to a transversal lines at pre-set intervals defined by the gummed areas to produce the bands.
  • the device comprises a control device controlling the timing between the gumming device and the cutting device. The timing is compared with a pre-set value and is corrected, using a correction device in order to eliminate any variation of the pre-set value.
  • the technical purpose which forms the basis of this invention is to propose a machine and a method for making plug wraps for the tobacco industry to overcome one or more of the above mentioned drawbacks of the prior art.
  • this invention has for an aim to provide a machine for making plug wraps for the tobacco industry capable of cutting a continuous web into individual plug wraps in a precise and effective manner.
  • Another aim of this invention is to provide a method for making plug wraps for the tobacco industry which allows efficiently synchronising the continuous feeding of the web along its feed path with the instant each plug wrap is cut from the web.
  • This invention also has for an aim to improve the efficiency of the plug wrap production process to guarantee a high quality of the articles comprising plug wraps made using this machine and/or this method.
  • the technical purpose indicated and the aims specified are substantially achieved by a machine and a method for making plug wraps for the tobacco industry, comprising the technical features described in one or more of the appended claims.
  • this invention provides a machine for making plug wraps for the tobacco industry, comprising:
  • the machine also comprises:
  • the invention also provides a method for making plug wraps for the tobacco industry, comprising the steps of:
  • the method also comprises the following steps:
  • plug wraps can be cut at an intermediate position between consecutive additional elements.
  • machine 100 denotes in its entirety a machine for making plug wraps for the tobacco industry, hereinafter referred to simply as machine 100.
  • plug wrap denotes a length of paper web adapted to be wrapped at least partly around at least two rod-shaped segments of material for the tobacco industry in order to connect the rod-shaped segments to each other.
  • wrapping the plug wrap in order to join the segments to make an article for the tobacco industry is carried out at a rolling station, not illustrated in the accompanying drawings, downstream of the machine 1 according to this invention, using a rolling process of known type.
  • the machine 100 comprises an unwinding station 20 configured to unwind a continuous web 1 of wrapping material for the tobacco industry from a roll 2 along a feed path P.
  • the continuous web 1 has on one side 1a a succession of equispaced additional elements 3.
  • the web 1 is provided, in particular, with a succession of pairs of rectangular additional elements 3 placed side by side at an equal spacing H along the longitudinal extension of the web 1.
  • the additional elements 3 may be defined by one or more of the following: features made on the web 1 (for example, printing, embossing, spray-on substances, perforations, slits) or applications of labels, patches, tear tapes or stickers.
  • the machine 1 also comprises a cutting station 30 disposed along the feed path P and configured to transversely cut the continuous web 1 by making a succession of cuts (along a cutting line T) at a predetermined position.
  • the plug wraps can be cut at a predetermined intermediate position between consecutive additional elements 3. Cutting allows making a succession of plug wraps 4, each comprising at least one additional element 3.
  • each plug wrap 4 comprises two additional elements 3 placed side by side along a direction perpendicular to the cutting line T, according to the embodiment illustrated in Figure 2 , so as to define a double plug wrap for rolling double filters interposed between pairs of axially juxtaposed segments.
  • the cutting line T is suitably interposed between consecutive additional elements 3 at a distance D from the front edge 3a of each additional element 3, so as to make plug wraps 4 comprising pairs of additional elements 3 placed side by side and disposed at a distance D' from the front edge 4a of the plug wrap 4.
  • the distance D' is essential for the distance D' to fall within a certain range of reference values, preferably between 0 mm and 2 mm.
  • the cutting station 30 comprises a suction drum 31 configured to rotate about a respective axis and, during rotation, to hold down a front portion 1' of the continuous web 1 by air suction.
  • the cutting station 30 also comprises a cutting roller 32 operating in conjunction with the suction drum 31 to make the succession of cuts on the front portion 1' of the continuous web 1 held on the suction drum 31.
  • the cutting drum 32 and the suction drum 31 are preferably configured to separate the plug wraps 4 from the continuous web 1 by impact cutting.
  • the cutting roller 32 comprises a plurality of blades 33 disposed at an equal spacing along the peripheral mantle of the cutting roller 32.
  • the rotation speed of the suction drum 31 is such that its tangential speed is greater than the unwinding speed of the continuous web 1 so as to automatically space the plug wraps 4.
  • the machine 100 comprises a detecting device 40 disposed upstream of the cutting station 30 and configured to detect the position of the additional elements 3 of the continuous web 1 along the feed path P.
  • the detecting device 40 comprises a sensor 41, for example an optical sensor.
  • the senor 41 may be configured to directly detect the position of the front edge 3a of the additional element 3 (for example by analysing the change in contrast of the continuous web 1) or to capture images of the web 1 with a photo camera or a video camera and to obtain from the images information regarding the position of the additional element 3.
  • the senor 41 may be configured to detect the change in the electromagnetic properties of the continuous web 1 to detect the position of additional elements 3 made of metallic material.
  • the machine 100 also comprises adjustment means 50 for adjusting the feed path P of the continuous web 1, disposed upstream of the cutting station 30 and configured to modify the geometry of the feed path P of the continuous web 1 in such a way as to adjust the position of the continuous web 1, hence of the additional elements 3, along the feed path P.
  • the adjustment means 50 allow varying the feed path P of the continuous web 1 in order to adjust the position of the continuous web 1 before it reaches the cutting station 30.
  • the machine 100 also comprises a control unit 60 connected to the detecting device 40 and to the adjustment means 50 and acting on the adjustment means 50 to set a variation in the feed path P of the continuous web 1 as a function of the position of each additional element 3 detected by the detecting device 40.
  • This invention thus makes it possible to instantaneously adjust the position of the web 1 by acting on its feed path P to ensure that the additional elements 3 are at a predetermined position when they reach the cutting station 30 so that the cutting lines T are made at the predetermined distance D.
  • control unit 60 sends a command to activate the adjustment means 50, which then suitably vary the feed path P to alter the position of the web 1 in such a way that the feeding and cutting of the web 1 are substantially re-synchronised relative to each other.
  • the plug wraps 4 obtained can be made to meet the required dimensional criteria at all times by operating on the feed path P of the continuous web 1 to compensate for any positioning errors that may have arisen between the unwinding station 20 and the detecting device 40.
  • the adjustment means 50 for adjusting the feed path P of the continuous web 1 are interposed between the detecting device 40 and the cutting station 30 so that adjustment is carried out just before cutting.
  • the adjustment means 50 preferably comprise a diverter 51 acting on the continuous web 1 to modify the feed path P of the continuous web 1 in such a way as to vary the length of the feed path P.
  • the diverter 51 is configured to lengthen or shorten the feed path P in such a way as to vary the position of the continuous web 1.
  • the diverter 51 comprises an eccentric or cam element, engaged in contact relation with a surface of the continuous web 1 - for example, the underside surface, opposite to the side 1a on which the additional elements 3 are located - and rotatable or oscillating about a respective axis of rotation 52.
  • the eccentric or cam element may be engaged in sliding contact relation with a surface of the web 1.
  • the diverter 51 is associated with a respective actuator, not illustrated in the accompanying drawings, to set a variation in the geometry of the continuous web 1, where the actuator is driven in a regulated manner by the control unit 60 as a function of the position of each additional element 3 detected by the detecting device 40.
  • the diverter 51 can press the continuous web 1 to shift the feed path P as a function of the position detected by the detecting device 40, for example by oscillating between a position A and a position B, as illustrated in Figure 1 , in such a way as to modify the feed path P between a position PA and position PB.
  • the diverter 51 can act on the continuous web 1 by oscillating towards the position B to alter the path P and determine a longer path PB which decreases the distance D on the continuous web 1 that will be fed to the cutting station 30.
  • the diverter 51 may, instead, be associated with a linear actuator with a stem that is transverse, preferably perpendicular, to the feed path P.
  • the machine 100 also comprises an inspecting device 70, preferably an optical sensor 71, disposed downstream of the cutting station 30 and configured to detect the position of the additional elements 3 on the individual plug wraps 4.
  • an inspecting device 70 preferably an optical sensor 71, disposed downstream of the cutting station 30 and configured to detect the position of the additional elements 3 on the individual plug wraps 4.
  • the inspecting device 70 advantageously monitors the quality of the plug wraps 4 that have been cut from the continuous web 1 in the cutting station 30.
  • the inspecting device 70 is connected to the control unit 60, which may be configured to set a further variation in the feed path P of the continuous web 1 as a function of the position of each additional element 3 detected by the inspecting device 70. That way, besides checking whether the cutting lines T have been made correctly, it is possible to obtain feedback regarding the feed path P if the previous adjustment has not had the desired effect or the plug wraps 4 obtained are progressively drifting towards an unacceptable value of the distance D'.
  • the inspecting device 70 is positioned in such a way as to optically inspect the plug wraps 4 preferably while they are being transported on the suction drum 31.
  • the machine 100 may comprise only the inspecting device 70 disposed downstream of the cutting station 30 and configured to detect the position of the additional elements 3 on the plug wraps 4.
  • the machine 100 may be without the detecting device 40 disposed upstream of the cutting station 30.
  • the inspecting device 70 is preferably an optical sensor 71.
  • the inspecting device 70 may perform inspection of the plug wraps 4 on a sample basis - that is, by inspecting only some of the plug wraps 4 that move past in front of it - or it may inspect all the plug wraps 4 one by one.
  • the inspecting device 70 advantageously monitors the quality of the plug wraps 4 that have been cut from the continuous web 1 in the cutting station 30.
  • the inspecting device 70 is advantageously connected to the control unit 60, which may be configured to set a further variation in the feed path P of the continuous web 1 as a function of the position of each additional element 3 detected by the inspecting device 70.
  • the inspecting device 70 is positioned in such a way as to optically inspect the plug wraps 4 preferably while they are being transported on the suction drum 31.
  • control unit 60 is connected to the unwinding station 20 to vary the unwinding speed of the continuous web 1 as a function of the position of the additional elements 3 detected by the detecting device 40 so as to correct the position, preferably uninterruptedly, of the additional elements at the cutting station 30.
  • This feedback control is particularly useful when the value of the distance D detected by the detecting device 40 is very different from the predetermined reference value or range of acceptable reference values, meaning that acting only on the adjustment means 50 might be insufficient to recover the correct position of the web 1 along the feed path P, that is to say, to reset the distance D to an acceptable value.
  • this invention also provides a method for making plug wraps 4 for the tobacco industry, comprising the steps of:
  • detecting the position of the additional elements 3 makes it possible to adjust the position of the continuous web 1 as a function of the position of the additional elements 3 detected in such a way that the step of cutting is synchronised at all times with the feeding of the continuous web 1, allowing the continuous web 1 to be cut correctly to obtain plug wraps 4 of excellent quality.
  • the step of detecting is carried out by an optical sensor 41 to capture the absolute position of each additional element 3 at least along the feed path P.
  • the control unit 60 applies a variation to the feed path P to lengthen/shorten the feed path P up to the cutting point, thereby compensating for the imprecision.
  • the step of detecting can be carried out by detecting the front edge 3a of each additional element 3 so as to constantly check whether the distance D of the next cutting line T to be made is acceptable.
  • the step of detecting may comprise a sub-step of comparing the position of each additional element 3 detected with a reference position and the method may thus comprise a step of activating the step of adjusting if the position detected does not meet predetermined acceptability criteria.
  • the step of varying the feed path P of the continuous web 1 is carried out by pressing the continuous web 1 with a diverter 51 transversely to the direction of extension of the continuous web 1 in such a way as to vary the length of the feed path P.
  • the diverter 51 is associated with a respective actuator, not illustrated in the accompanying drawings, and the step of varying the feed path P is carried out by acting on the actuator as a function of the detected position of each additional element 3.
  • the method after the step of cutting, also comprises a step of inspecting the position of the additional elements 3 on the individual plug wraps 4, more preferably by means of an optical sensor 71.
  • the step of inspecting is followed by a step of setting a further variation in the feed path P of the continuous web 1 as a function of the position of each additional element 3 detected on the plug wraps 4 in the step of detecting, in such a way as to further adjust the position of the continuous web 1, hence of the additional elements 3, along the feed path P.
  • the step of detecting comprises a sub-step of comparing the position of each additional element 3 detected with a reference position and the method thus comprises a step of activating the step of adjusting if the position detected does not meet predetermined acceptability criteria.
  • the step of adjusting comprises a sub-step of varying the unwinding speed of the continuous web 1 as a function of the detected position of the additional elements 3, so as to correct the position of the additional elements 3, preferably uninterruptedly, during the step of cutting.
  • This invention achieves the aims, overcoming the disadvantages of the prior art, by providing the user with a machine and a method for making plug wraps, capable of improving the efficiency of the production process by proposing operating solutions ensuring that the continuous web 1 will be cut correctly in order to obtain plug wraps 4 that meet production needs.
  • the invention allows preventing the quality of the plug wraps 4 made from being negatively affected by the unsteadiness which the continuous web 1 is potentially, and often inevitably, subjected to between the unwinding station 20 and the cutting station 30, also on account of the very nature of the material the web 1 is made of.
