- FIGS. 1 and 2 For example, an apparatus of the aforementioned type is shown in an exemplary first embodiment.
- a guide tube 2 which at its according to the FIGS. 1 and 2 right front end has an inlet and there opens to a funnel 4.
- the guide tube 2 serves to receive a tow line (not shown), which is moved by the guide tube 2 in the transport direction according to arrow A.
- the guide tube 2 has a substantially circular cross-section.
- the inner diameter of the guide tube 2 must be at least slightly larger than the outer diameter of the Towstranges so that the tow strand does not get stuck in the guide tube 2; if necessary, the diameter of the guide tube 2 but also be significantly larger than the diameter of the tow rope therein and be for example in a range of about 30 to 60 mm.
- the guide tube 2 may have a length of about 100 to 300 mm. After all, therefore, the guide tube 2 in the device forms a channel-shaped guide section for the Towstrang.
- the guide tube 2 terminates downstream of a housing 6 designed as a rotary body.
- the housing 6 is provided with an outlet 8, through which the tow line the illustrated device in order then to be subjected to further processing steps, which in particular comprise a wrapping with paper, preferably with simultaneous bonding, in a downstream of the device shown (not shown in the figures) format and dividing the tow strand into discrete filter rods in a downstream (also not shown in the figures) comprises cutting device.
- FIG. 1 Furthermore, it can be seen on the housing 6 also still a tubular connection is provided, which is an air outlet 10, whose function will be described in more detail below.
- a feed device for feeding in additives, furthermore, a feed device is provided, which in the first embodiment according to FIGS FIGS. 1 and 2 a plurality of feed tubes 12 which enter from the outside through the wall 14 of the guide tube 2 in the interior and ends there with its end portion 12a.
- a feed tube 12 which enter from the outside through the wall 14 of the guide tube 2 in the interior and ends there with its end portion 12a.

- the feed tubes 12 with its end portion 12a additionally inclined at an angle relative to the transport direction according to arrow A and thus also with respect to the center axis of the guide tube 2, not shown in the figures, wherein the angle greater than 0 ° and less than 90 ° is and should preferably be in a range of 5 ° to 45 °.
- the supply pipes 12 are divided in two in the transport direction according to arrow A successively arranged groups of three feed tubes 12 and distributed over the circumference of the guide tube 2 in the embodiment shown therein.
- This alignment has the consequence that in the illustrated embodiment, the feed tubes 12 are arranged to converge each other, such as FIG. 2 recognize.
- FIG. 2 the example of a feed tube 12 with the reference numeral "6" indicated schematically. Due to the fact that the end sections 12a terminating at their outlet 16 are essentially rectilinear and thus designed as a substantially straight pipe section or straight pipe section, the additive exits the outlet 16 as a jet, which, for reasons of clarity, is not illustrated in the drawings is shown.
- the feed tube 12 at least as far as they are shown, formed not only within, but also outside of the guide tube 2 as a straight pipe.
- the angular orientation of the located within the guide tube 2 end portions 12a of the feed tubes 12 has the result that when dispensed from the feed tubes 12, the additive or additives over a larger cross-sectional area in the already round towstring can be distributed and a selective feed of the additive or the additive is avoided.
- the orientation of the feed tubes 12 and in particular of the end portions 12a is selected so that the release of the additive takes place in the downstream direction and thus approximately in the transport direction according to arrow A. This has the consequence that the additive discharged from the outlet 16 of the end section 12a of the feed tubes 12 is entrained by the tow line moving in the direction of transport according to arrow A.
- the diameter of the feed tubes 12 is significantly smaller than the inner diameter of the guide tube 2, as the FIGS. 1 and 2 reveal.
- the feed tubes 12 may also be referred to as tubes in relation to the guide tube 2.
- the fact that the supply pipes 12 are to be made as narrow as possible is due to the fact that the flow of the tow rope through the guide tube 2 from the protruding end portions 12a of the feed tubes 12 may not be hindered too much. Rather, for proper movement of the tow string through the guide tube 2, sufficient space still remains between the end portions 12a of the feed tubes 12 to give the tow rope sufficient opportunity to flow around the end portions 12a of the feed tubes 12.
- the transport of the additive through the supply pipes 12 takes place by means of compressed air, for which purpose a compressed air source, not shown in the figures, is to be connected to the supply pipes 12.
- a compressed air source not shown in the figures
- the additive for its transport through the supply pipes 12 is applied, accelerated at the outlet 16 of the corresponding feed pipe 12 and entrained by the revolving round Towstrang.
- the compressed air After exiting the feed pipes 12, the compressed air enters the housing 6 and is sucked out of it through the air outlet 10.
- the transport nozzle 18 is located downstream of the feed of the additives through the feed tubes 12.
- Towstrang not shown in the figures from the guide tube 2 in the housing 6 and there passes through the transport nozzle 18 before it exits the outlet 8.
- Suction bell 20 connects to the housing 6 downstream, at the downstream end of the outlet 8 is formed.
- the suction bell 20 serves to catch excess additive, which is then sucked off via the air outlet 10.
- an inlet funnel 22 is further arranged downstream of the transport nozzle 18.
- the inlet funnel 22 is surrounded by the suction bell 20, which is to be considered in this respect as an extension of the housing 6.
- FIGS. 3 to 5 a second embodiment is shown, which differs from the first embodiment according to the FIGS. 1 and 2 differs by a different arrangement and orientation of the feed pipes for the feed of the additives.
- the construction of the second embodiment corresponds to that of the first embodiment, so that in this respect to the description of the first embodiment with reference to FIGS. 1 and 2 is referenced.
- the inlet funnel 22 is not shown, which, moreover, if necessary, can also be omitted.
- the feed device is formed by a tube bundle 30, to which a plurality of feed tubes 32 are combined together physically.
- the tube bundle 30 does not occur at a relatively shallow angle, but at a relatively steep angle through the wall 14 of the guide tube 2, wherein the angle up to 90 degrees with respect to the transport direction according to arrow A or not can be shown center axis of the guide tube 2.
- the supply pipes 32 are not rectilinear in the second embodiment, but have upstream of their end portion 32a a bent portion 32b, which forms approximately a quarter circle in the illustrated embodiment. The bent portion 32 b ensures that the feed tubes 32 are aligned with its end portion 32 a in the transport direction according to arrow A or in the direction of the central axis of the guide tube 2, not shown, such as FIG. 5 recognize.
- FIG. 5 recognize that in the illustrated embodiment, the tube bundle 30 in the region of the end portions 32a of the feed tubes 32 is aligned approximately centrally within the guide tube 2. The latter has the consequence that from the outlets 36 of the end portions 32a of the feed tubes 32, the additives indeed emerge as parallel rays. However, since the tube bundle 30 in the region of the outlets 36 extends over a certain cross-sectional area, such as FIG. 5 can be seen, this configuration also leads to a stronger distribution of the additives over the cross section of the guided through the guide tube 2 Towstranges.
- the cross-sectional area or the diameter of the tube bundle 30 compared to the inner diameter of the guide tube 2 is significantly smaller, whereby a significant obstruction of the tow strand is avoided during its movement through the guide tube 2; Rather, there is enough room for the Towstrang to move on both sides of the tube bundle 30 over.

Die Erfindung betrifft eine Vorrichtung zum Einbringen von Additiven in einen zur Herstellung eines Rauchartikels vorgesehenen und bereits rundgeformten Strang, mit einem Führungsabschnitt, durch den der Strang in Transportrichtung führbar ist, und einer in den Führungsabschnitt wirkenden Einspeiseeinrichtung zur stromabwärts gerichteten Einspeisung von Additiven in den im Führungsabschnitt befindlichen Strang.The invention relates to a device for introducing additives into a strand already provided for the production of a smoking article and having already a round shape, with a guide section through which the strand can be guided in the transport direction, and a feed device acting in the guide section for the downstream feeding of additives into the infeed Lead section strand.
Eine solche Vorrichtung wird insbesondere für die Herstellung von Zigarettenfiltern verwendet, so dass es sich in einem solchen Fall bei dem Strang um einen Filtertowstrang handelt. Mit dem Einbringen von Additiven lassen sich insbesondere die Leistungsfähigkeit des Rauchartikels verbessern und/oder dessen Geschmackseigenschaften gezielt beeinflussen. Das Einbringen von Additiven beispielsweise in einen Filtertowstrang zur Herstellung von Zigarettenfiltern führt auch zu einer Verbesserung der Filtereigenschaften, wozu häufig als Additiv Aktivkohlegranulat verwendet wird.Such a device is used in particular for the production of cigarette filters, so that in such a case the strand is a filter tow strand. With the introduction of additives, in particular, the performance of the smoking article can be improved and / or its taste properties can be specifically influenced. The introduction of additives, for example in a filter tow for the production of cigarette filters also leads to an improvement in the filter properties, which is often used as an additive activated carbon granules.

Auch wenn zur Zeit ein wesentlicher Anwendungsfall bei der Herstellung von Filtern liegt und insoweit es sich dann beim Strang um einen Filtertowstrang handelt, ist es aber auch denkbar, dass mit der vorliegenden Vorrichtung ebenfalls Tabakstränge entsprechend behandelt werden können. Somit sind unter "Rauchartikel" im Sinne der vorliegenden Erfindung Rauchartikel aller Art zu verstehen, unter die insbesondere Zigaretten, Filterzigaretten, Zigarillos und Zigarren sowie Teile von diesen fallen.Although "strand" is understood to mean an endless strand in the first place, it is not excluded for the purposes of the present invention that the strand to be processed may be finite if necessary and, for example, a total length of only a small multiple of the length of a tobacco or filter rod and possibly only in the order of magnitude of a rod. As previously indicated, various types of strands can be processed as are suitable for the manufacture of smoking articles. Although at present an essential application is in the production of filters and insofar as the strand is a filter tow strand, it is also conceivable that tobacco strands can also be treated accordingly with the present device. Thus, "smoking article" for the purposes of the present invention smoking articles of all kinds to understand, in particular cigarettes, filter cigarettes, cigarillos and cigars and parts of these fall.

Die Abgabe des Additivs oder der Additive in mindestens zwei Strahlen, die erfindungsgemäß winklig und somit disparallel zueinander orientiert sind, hat den vorteilhaften Effekt zur Folge, dass sich während der Einspeisung durch die Einspeiseeinrichtung das Additiv oder die Additive über einen größeren Bereich der Querschnittsfläche in dem bereits rundgeformten Strang verteilen lassen und eine punktuelle Einspeisung des Additivs oder der Additive vermieden wird.The delivery of the additive or of the additives into at least two jets, which according to the invention are oriented at an angle and thus disparallel to one another, has the advantageous effect that, during the feed through the feed device, the additive or the additives cover a larger area the cross-sectional area can be distributed in the already round-shaped strand and a selective feed of the additive or additives is avoided.
Vorzugsweise ist die Einspeiseeinrichtung derart ausgebildet, dass sie das Additiv oder die Additive in mindestens einem Strahl abgibt, der zusätzlich in einem Winkel größer als 0° und kleiner 90° zur Transportrichtung des Strahles gerichtet ist.Preferably, the feed device is designed such that it emits the additive or additives in at least one beam, which is additionally directed at an angle greater than 0 ° and less than 90 ° to the transport direction of the beam.
Desweiteren kann die Einspeiseeinrichtung derart ausgebildet sein, dass sie das Additiv oder die Additive in mindestens zwei in Transportrichtung des Stranges hintereinander liegenden Strahlen und/oder an mindestens einer innerhalb des Führungsabschnittes außermittig liegenden Stelle und/oder an mehreren um die Längsachse des Stranges verteilt angeordneten Stellen abgibt.Furthermore, the feed device may be designed such that it distributes the additive or additives in at least two beams lying one behind the other in the transport direction of the strand and / or at least one point located eccentrically within the guide section and / or at several points distributed around the longitudinal axis of the strand emits.
Sofern die Einspeiseeinrichtung mindestens zwei Einspeisemittel aufweist, kann mindestens ein Einspeisemittel mindestens mit einem Endabschnitt zusätzlich in einem Winkel größer als 0° und kleiner als 90° zur Transportrichtung des Stranges gerichtet sein. Bevorzugt können mindestens zwei Einspeisemittel in Transportrichtung des Stranges hintereinander und/oder mindestens mit ihren Endabschnitt zueinander konvergierend oder voneinander divergierend angeordnet sein. Desweiteren kann der Endabschnitt mindestens eines Einspeisemittels innerhalb des Führungsabschnittes außermittig angeordnet sein. Zweckmäßigerweise kann mindestens ein Einspeisemittel aus einem Rohr bestehen, dessen Endabschnitt offen ist und einen Auslass zur Abgabe eines Additivs bildet.If the feed device has at least two feed means, at least one feed means can additionally be directed at an end section at an angle greater than 0 ° and less than 90 ° to the transport direction of the strand. Preferably, at least two feed means can be arranged one behind the other in the transport direction of the strand and / or at least with their end section converging or diverging from one another.

Gemäß einem zweiten Aspekt der vorliegenden Erfindung wird vorgeschlagen, dass die Einspeiseeinrichtung zur Zuführung von Additiven mehrere im wesentlichen parallel zueinander verlaufende Zuführrohre aufweist, die an ihrem innerhalb des Führungsabschnittes liegenden Ende einen Auslass aufweisen, um das Additiv oder die Additive im wesentlichen in Transportrichtung des Stranges abzugeben, und zumindest an diesem Ende zu einem gemeinsamen Rohrbündel körperlich zusammengefasst sind.According to a second aspect of the present invention, it is proposed that the feed device for supplying additives has a plurality of feed pipes which are substantially parallel to one another and have an outlet at their end located inside the guide section in order to feed the additive or additives substantially in the transport direction of the strand and at least at this end are physically grouped into a common tube bundle.
Die erfindungsgemäße Bündelung mehrerer Zuführrohre zu einem gemeinsamen Rohrbündel führt ebenfalls zu einer stärkeren Verteilung des Additivs oder der Additive über die Querschnittsfläche des sich durch den Führungsabschnitt bewegenden Stranges. Dies wird erfindungsgemäß dadurch erreicht, dass sich das Rohrbündel im Bereich der Auslässe über eine gewisse Querschnittsfläche erstreckt. Somit wird auch bei dieser Ausführung eine punktuelle Einspeisung von Additiv in den Strang vermieden.The bundling of a plurality of feed tubes according to the invention into a common tube bundle likewise leads to a greater distribution of the additive or of the additives over the cross-sectional area of the strand moving through the guide section. This is inventively achieved in that the tube bundle extends in the region of the outlets over a certain cross-sectional area. Thus, even in this embodiment, a selective feed of additive is avoided in the strand.

Vorzugsweise weist der Führungsabschnitt einen Kanal auf, entlang dessen der Strang führbar ist.Preferably, the guide portion has a channel along which the strand is feasible.
Der Führungsabschnitt kann vorteilhaft so ausgebildet sein, dass der Strang zumindest im Bereich der Einspeiseeinrichtung im wesentlichen geradlinig führbar ist.The guide section may advantageously be designed such that the strand can be guided substantially rectilinearly, at least in the area of the feed device.
Vorzugsweise kann eine pneumatische Einrichtung zur Erzeugung von den Strang im Führungsabschnitt beaufschlagender Transportluft vorgesehen sein, um den Strang in Transportrichtung durch den Führungsabschnitt zu bewegen. Ebenfalls kann bevorzugt eine pneumatische Einrichtung zur Erzeugung von das Additiv oder die Additive beaufschlagender Transportluft in der Einspeiseeinrichtung vorgesehen sein, um das Additiv oder die Additive durch die Einspeiseeinrichtung in den Führungsabschnitt einzuspeisen.Preferably, a pneumatic device for generating the strand in the guide section acting transport air may be provided to move the strand in the transport direction by the guide portion. Also preferably, a pneumatic device for generating the additive or the additives acting on transport air may be provided in the feed device to feed the additive or additives through the feed device in the guide section.
Ein bevorzugter Verwendungszweck der Einspeiseeinrichtung besteht in der Applikation von im wesentlichen granulatförmigem Additiv.A preferred use of the feed device consists in the application of substantially granular additive.
Die erfindungsgemäße Vorrichtung wird bevorzugt zum Einbringen von Additiven in einen zur Herstellung eines Filters für einen Rauchartikel vorgesehenen und bereits rundgeformten Filtertowstrang verwendet.The device according to the invention is preferably used for introducing additives into a filter tow line intended for the production of a filter for a smoking article and already round-shaped.

Mit Hilfe der nachfolgend im Einzelnen beschriebenen Vorrichtung sollen Additive in einen bereits rundgeformten Towstrang eingebracht bzw. eingespeist werden. Insbesondere wird eine solche Vorrichtung für die Herstellung von Zigarettenfiltern verwendet, so dass es sich in einem solchen Fall bei dem Towstrang um einen Filtertowstrang handelt. Häufig wird Zelluloseacetat als Material für die Herstellung von Zigarettenfiltern verwendet. Mit dem Einbringen von Additiven in das Filtertow lassen sich beispielsweise die Leistungsfähigkeit und Filtereigenschaft des Filters verbessern und/oder der Geschmack gezielt beeinflussen; insbesondere für den erstgenannten Fall wird als Additiv Aktivkohlegranulat verwendet. An dieser Stelle sei angemerkt, dass in den Zeichnungen aus Gründen einer besseren Übersichtlichkeit weder der Towstrang noch das Additiv abgebildet sind.With the help of the apparatus described in detail below, additives are to be introduced or fed into an already round-shaped tow line. In particular, such a device is used for the production of cigarette filters, so that in such a case the tow strand is a filter tow strand. Often, cellulose acetate is used as a material for the manufacture of cigarette filters. By introducing additives into the filter tow, for example, the performance and filter properties of the filter can be improved and / or the taste can be purposefully influenced; in particular for the former case, activated carbon granules are used as additive. At this point, it should be noted that in the drawings, for reasons of clarity, neither the tow strand nor the additive are depicted.

Es ist aber auch denkbar, zumindest für einen Teil der Zuführrohre eine alternative Orientierung derart zu wählen, dass zumindest einige der Zuführrohre mit ihrem Endabschnitt voneinander divergierend innerhalb des Führungsrohres 2 verlaufen. Ebenfalls ist es alternativ oder zusätzlich denkbar, mindestens ein Zuführrohr mindestens mit seinem Endabschnitt winklig gegenüber der Transportrichtung gemäß Pfeil A oder der nicht dargestellten Mittelachse des Führungsrohres 2 versetzt und somit gegenüber einer radialen Orientierung versetzt anzuordnen.However, it is also conceivable to choose an alternative orientation for at least some of the feed pipes in such a way that at least some of the feed pipes extend with their end portion from one another divergently within the
An der Stirnseite ihres freien Endes der innerhalb des Führungsrohres 2 befindlichen Endabschnitte 12a der Zuführrohre 12 ist ein Auslass für die Abgabe des durch das Zuführungsrohr 12 zugeführten Additivs ausgebildet; dieser Auslass ist in
Die winklige Orientierung der innerhalb des Führungsrohres 2 befindlichen Endabschnitte 12a der Zuführrohre 12 hat zur Folge, dass sich bei Abgabe aus den Zuführrohren 12 das Additiv oder die Additive über eine größere Querschnittsfläche in dem bereits rund geformten Towstrang verteilen lassen und eine punktuelle Einspeisung des Additivs oder der Additive vermieden wird.The angular orientation of the located within the

Der Durchmesser der Zuführrohre 12 ist deutlich kleiner als der Innendurchmesser des Führungsrohres 2, wie die
Vorzugsweise erfolgt der Transport des Additivs durch die Zuführrohre 12 mittels Druckluft, wozu eine in den Figuren nicht dargestellte Druckluftquelle an die Zuführrohre 12 anzuschließen ist. Dadurch wird das Additiv für seinen Transport durch die Zuführrohre 12 beaufschlagt, am Auslass 16 des entsprechenden Zuführrohres 12 beschleunigt angeboten und vom umlaufenden runden Towstrang mitgerissen. Nach Austritt aus den Zuführrohren 12 gelangt die Druckluft in das Gehäuse 6 und wird aus diesem durch den Luftauslass 10 abgesogen.Preferably, the transport of the additive through the

Zusätzlich ist es aber auch denkbar, eine Transportdüse am Einlass 4 des Führungsrohres 2 oder stromaufwärts vom Führungsrohr 2 vorzusehen, wodurch vor Einspeisung der Additive das Tow entsprechend günstig aufbereitet werden kann. Im Übrigen unterstützt die so erzeugte Transportluft die Abgabe der Additive aus den Zuführrohren 12. Der Luftauslass 10 am Gehäuse 6 ermöglicht außerdem auch die Ableitung überschüssiger Transportluft.In addition, it is also conceivable to provide a transport nozzle at the
Im dargestellten Ausführungsbeispiel schließt sich an das Gehäuse 6 stromabwärtsseitig eine sog. Absaugglocke 20 an, an deren stromabwärtsseitigen Ende der Auslass 8 ausgebildet ist. Die Absaugglocke 20 dient dazu, überschüssiges Additiv aufzufangen, welches dann über den Luftauslass 10 abgesaugt wird. Wie

Zwar erfolgt ähnlich wie bei der ersten Ausführung die Einspeisung der Additive über Röhrchen, jedoch wird bei der zweiten Ausführung die Einspeiseeinrichtung von einem Rohrbündel 30 gebildet, zu welchem mehrere Zuführrohre 32 gemeinsam körperlich zusammengefaßt sind. Anders als bei der ersten Ausführung tritt das Rohrbündel 30 nicht in einem relativ flachen Winkel, sondern in einem relativ steilen Winkel durch die Wandung 14 des Führungsrohres 2, wobei der Winkel bis zu 90 Grad gegenüber der Transportrichtung gemäß Pfeil A bzw. der nicht dargestellten Mittelachse des Führungsrohres 2 betragen kann. Ebenfalls anders als bei der ersten Ausführung sind bei der zweiten Ausführung die Zuführohre 32 nicht geradlinig gestaltet, sondern weisen stromaufwärts vor ihrem Endabschnitt 32a einen gebogenen Abschnitt 32b auf, der im dargestellten Ausführungsbeispiel etwa einen Viertelkreisbogen bildet. Der gebogene Abschnitt 32b sorgt dafür, dass die Zuführrohre 32 mit ihrem Endabschnitt 32a in Transportrichtung gemäß Pfeil A bzw. in Richtung der nicht dargestellten Mittelachse des Führungsrohres 2 ausgerichtet sind, wie
