Definitions
- the invention relates to an arrangement for the production of coaxial filters for rod-shaped smoking articles, such as cigarettes, with a for producing a paper-wrapped simple filter strand, but no cutting function exercising filter strand manufacturing device, a processing unit for processing a FiltertowstMails, a further processing device, in particular a strand-making machine, as which is provided for further processing of simple filter towers further processing device, and a Koaxialher einsvorraum with a wrapping device which is designed to wrap the filter strand with the filter tow as an additional filter tow to form a Koaxialfiltertowstranges, a filter strand web, along which the filter strand in the direction of its longitudinal extension to the wrapping device is movable, and a tow guideway along which d he additional filter tow is movable in the direction of its longitudinal extent to the wrapping device.
- the US Pat. No. 3,860,011 discloses a method and apparatus for making a filter rod for cigarette filter mouthpieces wherein a material flow of fibrous filter material as well as porous paper and the paper is wrapped around the fibrous filter material to form a filter rod.
- a hose body is continuously fed, around which a continuous stream of material of fibrous material is arranged, before continuously fed paper surrounds the continuously fed fiber material.
- the filter rod is in turn moved to continue the movement of the three material flows, while the fiber material is pressed against the hose body or a tube for entering a frictional engagement hereby for the purpose of uniform feed.
- a device for concentrically embedding a length of the tube in the filter material is used to frictionally engage the filter material with the tube under a compressive force distributed over the circumference.
- Coaxial filters for rod-shaped smoking articles and in particular for cigarettes are known (eg from the US 3,396,061 A ) and have an inner, formed into a round bar soul, which is surrounded by an outer sheath. Both the inner core and the outer cover are each made of filter tow material.
- the characteristic of a coaxial filter is that the filter tow material used for the core differs from the filter tow material forming the outer envelope, for example, in terms of material, density, stiffness, and the additives contained therein.
- the permeability, the filtration properties and / or the taste and thus the smoking behavior and / or mechanical properties such as stiffness can be selectively influenced in a desired manner.
- coaxial filters of the type can be produced in which a further paper layer is contained between the inner core and the outer wrapping layer. This paper layer thus separates the outer wrapping layer of the inner soul.
- the invention now proposes to use a filter strand produced with a conventional filter production plant and wrapped in paper and to wrap it with an additional filter tow, which is provided by a further conventional filter treatment unit, and the filter tow strand formed therefrom in a downstream one further conventional further processing device, in particular strand production machine, to gozuver-to coaxial filter rods provided with an intermediate layer of paper.
- the solution according to the invention allows to a greater extent the use of previously used for the production of simple, so single-layer filter strands or bars components.
- filter tows eg cellulose acetate
- filter tows are stripped from a bale, prepared by stretching and treating with plasticizer, round-shaped and delivered in a desired shape and consistency for further processing to a further processing device or strand manufacturing machine, which from the prepared filter tow strips by wrapping with a wrapping material strip produces a filter strand, which is finally cut into filter rods for cigarettes or other rod-shaped smoking articles.
- a conventional system is now used according to the present invention for the production of the inner core for paper-lined coaxial filter rods or rods, wherein the further processing device or strand production machine is to operate without cutting function by either the cutting function is switched off or a cutting device is not provided from the outset.
- a modification means no significant expense.
- the invention makes use of the knowledge that with such a system a strand already wrapped with paper is provided, which can thus be used in a simple and skilful manner as inner soul for the production of the coaxial filter in question here.
- a separate device is not required because of the inner soul to be used as a filter strand is already supplied with a Textilumhüllung.
- a further processing unit is required, through which a correspondingly prepared additional filter tow strip is made available.
- This additional treatment unit is also a conventional component available on the market.
- the device according to claim 1 is needed.
- the coaxial filter strand formed in this way is further processed in a further processing device or strand production machine, which is likewise to be provided additionally and is originally intended for further processing of single or single-layer filter tow strips.
- acts It is also in this additional processing device or strand manufacturing machine to a conventional and already available on the market machine.
- the invention provides an economically advantageous solution because four out of five components make use of existing conventional devices or machines that need to undergo only minor modifications and adaptations, if any, while providing a specifically designed system significantly higher would require effort, however, avoided by the solution according to the invention in a clever way.
- filter strand web and "tow web” primarily mean the path along which the filter strand or filter tow strip moves.
- the filter strand web and / or the Tow Equipmentsbahn be provided with a web guide, which leads the filter strand or filter tows supportive.
- a track guide is at least not consistently mandatory.
- the third interface may be designed for connection to the inlet-side interface of the web of a conventional one-line further processing device, in particular a strand production machine, provided for further processing of simple filter tow strips.
- a multi-lane, preferably two-lane, further processing device can also be used for such further processing of the coaxial filter strand, so that in this case the third interface is designed for selective coupling to an inlet-side interface of one of a plurality of lanes, such a further processing device.
- the unused tracks are turned off or blocked in the multi-lane further processing device and thus not used;
- such a measure is economically advantageous, since even with a single-lane use of a multi-lane post-processing device on an existing device or machine is used, which - if at all - only slight modifications and adaptations needs to be subjected, while providing a specifically designed device or machine would require a much higher effort at this point.
- each lane is usually assigned at least one processing unit.
- the remaining tracks are blocked or turned off, so that expediently also those other webs associated processing units should be turned off, on the one hand, an unnecessary load To avoid this then not effectively used processing units and on the other to save a caused by the operation of these units unnecessary energy consumption.
- the strand forming units which are generally present in the multi-web further processing device should therefore preferably be designed to be switched off selectively.
- the cutting devices which are likewise generally also provided in a multi-lane further processing device should optionally be able to be switched off, wherein in the case of switching off a cutting device, the associated blade can preferably be brought into a rest position outside the lane.
- a pivot mechanism may be provided, through which the knife is folded away. The movement of the knife when not in use in a rest position outside the track is used in particular for safety.
- each web of the multi-lane further processing device can be assigned a switch-off push-in drum.
- the further processing device may have at least one transfer spider, with interchangeable shoes for takeover and onward transport is provided by cut from the coaxial filter strand filter rods.
- the filter strand web and the tow guide web should lie substantially one above the other.
- the filter strand web and / or the tow guide web can have at least one wedge groove over which the filter strand or the additional filter tow strip is guided.
- the tow guide track can have at least one roller over which the filter tow strip is guided. Since the filter tow strip is used to form the outer layer or casing for the coaxial filter and is therefore wrapped around the filter strand from the outside in the wrapping device, the filter tow strip along the second tow path is at least initially moved in a substantially expanded shape in the direction of its longitudinal extent. Therefore, that roller should preferably be provided with a smooth or slightly concave curved surface. By using a concavely curved lateral surface of the filter tow can already be preformed a little by getting at least a slight curvature transverse to its longitudinal extent, with which he then runs into the wrapping device, whereby the wrapping process takes place there is somewhat simplified.
- the wrapping device has a hollow inlet or wrapping finger, which tapers in the conveying direction, through which the filter strand and the additional filter tow strip are guided together and the filter tow strip is placed around the filter tow line.
- the preferred inlet or wrapping finger has a cup or funnel shape, the inner surface of which forms a guide for the outer filter tow strip and, due to the increasing cross-sectional constriction in the transport direction, causes the filter tow to move around the belt as it progresses through the runner or wrapping finger at the same time also by the inlet or wrapping finger out led filter tow line sets.

Mit Hilfe der Erfindung lassen sich Koaxialfilter derjenigen Art herstellen, bei welcher zwischen der inneren Seele und der äußeren Umhüllungslage noch eine weitere Papierlage enthalten ist. Diese Papierlage trennt also die äußere Umhüllungslage von der inneren Seele. Ein solcher Filteraufbau ist nicht nur vorteilhaft für eine gezielte Beeinflussung und Adaption der Filterungseigenschaften, sondern auch zur Erhöhung der mechanischen Steifigkeit des Filterkörpers.With the aid of the invention, coaxial filters of the type can be produced in which a further paper layer is contained between the inner core and the outer wrapping layer. This paper layer thus separates the outer wrapping layer of the inner soul.

Für die Herstellung derartiger Koaxialfilter schlägt nun die Erfindung vor, einen mit einer herkömmlichen Filterproduktionsanlage hergestellten und mit Papier umhüllten Filterstrang zu verwenden und diesen mit einem zusätzlichen Filtertowstreifen zu umhüllen, welcher von einer weiteren herkömmlichen Filteraufbereitungseinheit bereitgestellt wird, und den daraus gebildeten Filtertowstrang in einer nachgeschalteten weiteren herkömmlichen Weiterverarbeitungseinrichtung, insbesondere Strangherstellungsmaschine, zu mit einer Zwischenlage aus Papier versehenen Koaxialfilterstäben weiterzuverarbeiten.For the production of such coaxial filters, the invention now proposes to use a filter strand produced with a conventional filter production plant and wrapped in paper and to wrap it with an additional filter tow, which is provided by a further conventional filter treatment unit, and the filter tow strand formed therefrom in a downstream one further conventional further processing device, in particular strand production machine, to weiterzuverarbeiten to coaxial filter rods provided with an intermediate layer of paper.
Demnach erlaubt die erfindungsgemäße Lösung in größerem Umfang den Einsatz von bislang für die Herstellung von einfachen, also einlagigen Filtersträngen bzw. -stäben verwendeten Komponenten. Hierbei handelt es sich zum einen um Module, Maschinen oder Vorrichtungen zur Aufbereitung von Filtertowstreifen und zum anderen um Weiterverarbeitungsvorrichtungen bzw. Strangherstellungsmaschinen zur Weiterverarbeitung der aufbereiteten Filtertowstreifen zu Filtersträngen oder Filterstäben, welche zum Aufbau von herkömmlichen Filterproduktionsanlagen zur Herstellung von einfachen, also einlagigen Filterstäben verwendet werden. In einer solchen herkömmlichen Filterproduktionsanlage werden durch eine Aufbereitungseinheit Filtertowstreifen (z.B. aus Celluloseacetatfäden) von einem Ballen abgezogen, durch Strecken und Behandeln mit Weichmacher aufbereitet, rundgeformt und in einer dadurch gewünschten Form und Konsistenz zur Weiterverarbeitung an eine Weiterverarbeitungsvorrichtung bzw. Strangherstellungsmaschine abgegeben, welche aus dem aufbereiteten Filtertowstreifen durch Umhüllung mit einem Hüllmaterialstreifen einen Filterstrang herstellt, der schließlich in Filterstäbe für Zigaretten oder andere stabförmige Rauchartikel zerschnitten wird. Eine solche herkömmliche Anlage wird nun gemäß der vorliegenden Erfindung zur Herstellung der inneren Seele für mit einer Zwischenlage aus Papier versehene Koaxialfilterstränge bzw. -stäbe genutzt, wobei die Weiterverarbeitungsvorrichtung bzw. Strangherstellungsmaschine ohne Schneidefunktion zu betreiben ist, indem entweder die Schneidefunktion abgeschaltet wird oder eine Schneideeinrichtung von vornherein nicht vorgesehen ist. Eine solche Modifikation bedeutet jedoch keinen wesentlichen Aufwand. Dabei macht sich die Erfindung die Erkenntnis zunutze, dass mit einer solchen Anlage ein bereits mit Papier umhüllter Strang bereitgestellt wird, der somit auf einfache und geschickte Weise als innere Seele zur Herstellung des hier in Rede stehenden Koaxialfilters verwendet werden kann. Für das Einbringen der Zwischenlage aus Papier ist eine separate Vorrichtung nicht erforderlich, da der als innere Seele zu verwendende Filterstrang bereits mit einer Papierumhüllung geliefert wird.Accordingly, the solution according to the invention allows to a greater extent the use of previously used for the production of simple, so single-layer filter strands or bars components. These are on the one hand to modules, machines or devices for the preparation of filter towers and on the other to further processing devices or strand production machines for further processing of the processed filter towers to filter strands or filter rods, which for the construction of conventional filter production equipment for the production of simple, so single-layer filter rods be used. In such a conventional filter production line filter tows (eg cellulose acetate) are stripped from a bale, prepared by stretching and treating with plasticizer, round-shaped and delivered in a desired shape and consistency for further processing to a further processing device or strand manufacturing machine, which from the prepared filter tow strips by wrapping with a wrapping material strip produces a filter strand, which is finally cut into filter rods for cigarettes or other rod-shaped smoking articles. Such a conventional system is now used according to the present invention for the production of the inner core for paper-lined coaxial filter rods or rods, wherein the further processing device or strand production machine is to operate without cutting function by either the cutting function is switched off or a cutting device is not provided from the outset. However, such a modification means no significant expense. In this case, the invention makes use of the knowledge that with such a system a strand already wrapped with paper is provided, which can thus be used in a simple and skilful manner as inner soul for the production of the coaxial filter in question here. For the introduction of the intermediate layer of paper, a separate device is not required because of the inner soul to be used as a filter strand is already supplied with a Papierumhüllung.
Für die Herstellung der äußeren Umhüllungslage ist eine weitere Aufbereitungseinheit von Nöten, durch die ein entsprechend aufbereiteter zusätzlicher Filtertowstreifen zur Verfügung gestellt wird. Auch bei dieser zusätzlichen Aufbereitungseinheit handelt es sich um eine herkömmliche und auf dem Markt erhältliche Komponente. Um den bereits mit Papier umhüllten Filterstrang und den zuvor erwähnten zusätzlichen Filtertowstreifen zur Bildung eines Koaxialfilterstranges zusammenzuführen, ist ferner die Vorrichtung gemäß Anspruch 1 von Nöten. Der auf diese Weise gebildete Koaxialfilterstrang wird in einer weiteren Weiterverarbeitungsvorrichtung bzw. Strangherstellungsmaschine weiterverarbeitet, die ebenfalls zusätzlich vorzusehen ist und ursprünglich zur Weiterverarbeitung von einfachen bzw. einlagigen Filtertowstreifen bestimmt ist. Somit handelt es sich auch bei dieser zusätzlichen Weiterverarbeitungsvorrichtung bzw. Strangherstellungsmaschine um eine herkömmliche und bereits auf dem Markt erhältliche Maschine.For the production of the outer wrapping layer, a further processing unit is required, through which a correspondingly prepared additional filter tow strip is made available. This additional treatment unit is also a conventional component available on the market. In order to merge the already wrapped with paper filter strand and the aforementioned additional filter tow to form a Koaxialfilterstranges, also the device according to claim 1 is needed. The coaxial filter strand formed in this way is further processed in a further processing device or strand production machine, which is likewise to be provided additionally and is originally intended for further processing of single or single-layer filter tow strips. Thus acts It is also in this additional processing device or strand manufacturing machine to a conventional and already available on the market machine.
Demnach bietet die Erfindung eine wirtschaftlich vorteilhafte Lösung, da für vier von fünf Komponenten auf vorhandene herkömmliche Vorrichtungen bzw. Maschinen zurückgegriffen wird, die - wenn überhaupt - nur genringfügige Modifikationen und Adaptionen unterworfen zu werden brauchen, während die Bereitstellung einer spezifisch konstruierten Anlage einen deutlich höheren Aufwand bedingen würde, der mithilfe der erfindungsgemäßen Lösung jedoch auf geschickte Weise vermieden wird.Accordingly, the invention provides an economically advantageous solution because four out of five components make use of existing conventional devices or machines that need to undergo only minor modifications and adaptations, if any, while providing a specifically designed system significantly higher Would require effort, however, avoided by the solution according to the invention in a clever way.
In diesem Zusammenhang sei darauf hingewiesen, dass unter den Begriffen "Filterstrangbahn" und "Towführungsbahn" in erster Linie der Weg verstanden wird, entlang dessen sich der Filterstrang bzw. Filtertowstreifen bewegt. Selbstverständlich kann zumindest abschnittsweise die Filterstrangbahn und/oder die Towführungsbahn mit einer Bahnführung versehen sein, die den Filterstrang bzw. Filtertowstreifen unterstützend führt. Eine solche Bahnführung ist jedoch zumindest nicht durchgängig zwingend notwendig.It should be noted in this context that the terms "filter strand web" and "tow web" primarily mean the path along which the filter strand or filter tow strip moves. Of course, at least in sections, the filter strand web and / or the Towführungsbahn be provided with a web guide, which leads the filter strand or filter tows supportive. However, such a track guide is at least not consistently mandatory.
Bevorzugte Ausführungen und Weiterbildungen der erfindungsgemäßen Vorrichtung sind in den abhängigen Ansprüchen angegeben.Preferred embodiments and further developments of the device according to the invention are specified in the dependent claims.
Die dritte Schnittstelle kann zum Anschluss an die einlasseitige Schnittstelle der Bahn einer herkömmlichen zur Weiterverarbeitung von einfachen Filtertowstreifen vorgesehenen einbahnigen Weiterverarbeitungsvorrichtung, insbesondere Strangherstellungsmaschine, ausgebildet sein. Alternativ kann für eine derartige Weiterverarbeitung des Koaxialfilterstranges auch eine mehrbahnige, vorzugsweise zweibahnige, Weiterverarbeitungsvorrichtung verwendet werden, so dass in diesem Fall die dritte Schnittstelle zur wahlweisen Kopplung mit einer einlassseitigen Schnittstelle einer von mehreren Bahnen, einer solchen Weiterverarbeitungsvorrichtung ausgebildet ist. Zwar werden bei dieser letztgenannten alternativen Ausführung die unbenutzten Bahnen in der mehrbahnigen Weiterverarbeitungsvorrichtung abgeschaltet oder blockiert und somit nicht genutzt; jedoch ist eine solche Maßnahme wirtschaftlich vorteilhaft, da auch bei einbahniger Verwendung einer mehrbahnigen Weiterverarbeitungsvorrichtung auf eine vorhandene Vorrichtung bzw. Maschine zurückgegriffen wird, die - wenn überhaupt - nur geringfügigen Modifikationen und Adaptionen unterworfen zu werden braucht, während die Bereitstellung einer spezifisch konstruierten Vorrichtung oder Maschine auch an dieser Stelle einen deutlich höheren Aufwand erfordern würde.The third interface may be designed for connection to the inlet-side interface of the web of a conventional one-line further processing device, in particular a strand production machine, provided for further processing of simple filter tow strips. Alternatively, a multi-lane, preferably two-lane, further processing device can also be used for such further processing of the coaxial filter strand, so that in this case the third interface is designed for selective coupling to an inlet-side interface of one of a plurality of lanes, such a further processing device. Although in this latter alternative embodiment, the unused tracks are turned off or blocked in the multi-lane further processing device and thus not used; However, such a measure is economically advantageous, since even with a single-lane use of a multi-lane post-processing device on an existing device or machine is used, which - if at all - only slight modifications and adaptations needs to be subjected, while providing a specifically designed device or machine would require a much higher effort at this point.
In der stromabwärts gelegenen herkömmlichen zur Weiterverarbeitung von einfachen Filtertowstreifen vorgesehenen mehrbahnigen Weiterverarbeitungsvorrichtung, insbesondere Strangherstellungsmaschine, ist gewöhnlich jeder Bahn mindestens ein Bearbeitungsaggregat zugeordnet. Bei Anschluss einer aus den mehreren Bahnen ausgewählten Bahn mit ihrer einlassseitigen Schnittstelle an die dritte Schnittstelle werden, wie bereits erwähnt, die übrigen Bahnen gesperrt oder abgeschaltet, so dass zweckmäßigerweise auch die diesen übrigen Bahnen zugeordneten Bearbeitungsaggregate abgeschaltet werden sollten, um zum einen eine unnötige Beanspruchung dieser dann nicht effektiv genutzten Bearbeitungsaggregate zu vermeiden und zum anderen einen durch den Betrieb dieser Aggregate bedingten unnötigen Energieverbrauch einzusparen. Die in der Regel in der mehrbahnigen Weiterverarbeitungsvorrichtung vorhandenen Strangbildungsaggregate sollten deshalb bevorzugt wahlweise abschaltbar ausgeführt sein. Ferner sollten auch die ebenfalls in der Regel in einer mehrbahnigen Weiterverarbeitungsvorrichtung vorgesehenen Schneideeinrichtungen wahlweise abschaltbar sein, wobei im Falle des Abschaltens einer Schneideeinrichtung das zugehörige Messer bevorzugt in eine Ruhestellung außerhalb der Bahn verbringbar ist. Hierzu kann beispielsweise ein Schwenkmechanismus vorgesehen sein, durch den das Messer weggeklappt wird. Das Verbringen des Messers bei Nichtbenutzung in eine Ruheposition außerhalb der Bahn dient insbesondere der Sicherheit. Ferner kann jeder Bahn der mehrbahnigen Weiterverarbeitungsvorrichtung eine abschaltbare Einstoßtrommel zugeordnet sein.In the downstream conventional multi-lane further processing device provided for further processing of simple filter tow strips, in particular a strand-making machine, each lane is usually assigned at least one processing unit. When connecting a selected from the plurality of webs path with its inlet-side interface to the third interface, as already mentioned, the remaining tracks are blocked or turned off, so that expediently also those other webs associated processing units should be turned off, on the one hand, an unnecessary load To avoid this then not effectively used processing units and on the other to save a caused by the operation of these units unnecessary energy consumption. The strand forming units which are generally present in the multi-web further processing device should therefore preferably be designed to be switched off selectively. Furthermore, the cutting devices which are likewise generally also provided in a multi-lane further processing device should optionally be able to be switched off, wherein in the case of switching off a cutting device, the associated blade can preferably be brought into a rest position outside the lane. For this purpose, for example, a pivot mechanism may be provided, through which the knife is folded away. The movement of the knife when not in use in a rest position outside the track is used in particular for safety. Furthermore, each web of the multi-lane further processing device can be assigned a switch-off push-in drum.
Auch kann die Weiterverarbeitungsvorrichtung mindestens eine Übergabespinne aufweisen, die mit auswechselbaren Schuhen zur Übernahme und zum Weitertransport von aus dem Koaxialfilterstrang geschnittenen Filterstäben versehen ist.Also, the further processing device may have at least one transfer spider, with interchangeable shoes for takeover and onward transport is provided by cut from the coaxial filter strand filter rods.
Für eine Platz sparende Anordnung sollten die Filterstrangbahn und die Towführungsbahn im Wesentlichen übereinanderliegen.For a space-saving arrangement, the filter strand web and the tow guide web should lie substantially one above the other.
Zum Umlenken des Filterstranges bzw. des zusätzlichen Filtertowstreifens kann die Filterstrangbahn und/oder die Towführungsbahn mindestens eine Keilnutrolle aufweisen, über die der Filterstrang bzw. der zusätzliche Filtertowstreifen geführt wird.In order to divert the filter strand or the additional filter tow strip, the filter strand web and / or the tow guide web can have at least one wedge groove over which the filter strand or the additional filter tow strip is guided.
Zum Zwecke einer besseren Führung oder Umlenkung kann die Towführungsbahn mindestens eine Walze aufweisen, über die der Filtertowstreifen geführt wird. Da der Filtertowstreifen zur Bildung der äußeren Lage bzw. Umhüllung für den Koaxialfilter verwendet und deshalb in der Umhüllungseinrichtung von außen um den Filterstrang herumgelegt wird, wird der Filtertowstreifen entlang der zweiten Towführungsbahn zumindest zunächst in einer im Wesentlichen ausgebreiteten Form in Richtung seiner Längserstreckung bewegt. Deshalb sollte jene Walze bevorzugt mit einer glatten oder leicht konkav gewölbten Mantelfläche versehen sein. Durch die Verwendung einer konkav gewölbten Mantelfläche kann der Filtertowstreifen bereits ein wenig vorgeformt werden, indem er eine zumindest geringfügige Wölbung quer zu seiner Längserstreckung erhält, mit der er dann in die Umhüllungseinrichtung läuft, wodurch der dort stattfindende Umhüllungsvorgang etwas vereinfacht wird.For the purpose of better guidance or deflection, the tow guide track can have at least one roller over which the filter tow strip is guided. Since the filter tow strip is used to form the outer layer or casing for the coaxial filter and is therefore wrapped around the filter strand from the outside in the wrapping device, the filter tow strip along the second tow path is at least initially moved in a substantially expanded shape in the direction of its longitudinal extent. Therefore, that roller should preferably be provided with a smooth or slightly concave curved surface. By using a concavely curved lateral surface of the filter tow can already be preformed a little by getting at least a slight curvature transverse to its longitudinal extent, with which he then runs into the wrapping device, whereby the wrapping process takes place there is somewhat simplified.
Bei einer weiteren bevorzugten Ausführung der Erfindung weist die Umhüllungseinrichtung einen sich in Förderrichtung verjüngenden hohlen Einlauf- oder Umhüllungsfinger auf, durch den der Filterstrang und der zusätzliche Filtertowstreifen gemeinsam geführt werden und dabei der Filtertowstreifen um den Filtertowstrang gelegt wird. Demnach hat der bevorzugt verwendete Einlauf- oder Umhüllungsfinger eine Kelch- oder Trichterform, deren Innenfläche eine Führung für den außen liegenden Filtertowstreifen bildet und aufgrund der in Transportrichtung zunehmenden Querschnittsverengung bewirkt, dass sich der Filtertowstreifen während seiner fortschreitenden Bewegung durch den Einlauf- oder Umhüllungsfinger um den gleichzeitig ebenfalls durch den Einlauf- oder Umhüllungsfinger geführten Filtertowstrang legt.In a further preferred embodiment of the invention, the wrapping device has a hollow inlet or wrapping finger, which tapers in the conveying direction, through which the filter strand and the additional filter tow strip are guided together and the filter tow strip is placed around the filter tow line. Thus, the preferred inlet or wrapping finger has a cup or funnel shape, the inner surface of which forms a guide for the outer filter tow strip and, due to the increasing cross-sectional constriction in the transport direction, causes the filter tow to move around the belt as it progresses through the runner or wrapping finger at the same time also by the inlet or wrapping finger out led filter tow line sets.
Bevorzugt weist die herkömmliche ursprünglich zur Herstellung eines einfachen Filterstranges vorgesehene Filterstrangherstellungsvorrichtung, die erfindungsgemäß zur Herstellung einer bereits mit Papier umhüllten inneren Seele für den Koaxialfilterstrang verwendet wird, eine herkömmliche Aufbereitungseinheit zur Aufbereitung eines für die Herstellung der inneren Seele verwendeten Filtertowstreifens und eine nachgeschaltete Strangherstellungsmaschine auf, bei welcher allerdings die Schneidefunktion entfällt, da ja die mit Papier umhüllte innere Seele in Strangform für die anschließende Umhüllung mit dem zusätzlichen Filtertowstreifen vorliegen muss.Preferably, the conventional filter rod manufacturing apparatus originally provided for producing a simple filter strand, which is used according to the invention for producing an already encased inner core for the coaxial filter strand, comprises a conventional processing unit for processing a filter tow strip used for the production of the inner core and a downstream strand production machine, in which, however, eliminates the cutting function, since the enveloped with paper inner soul must be present in strand form for the subsequent wrapping with the additional filter tow.
Bei einer Weiterbildung dieser Ausführung kann mindestens ein Abschnitt der Aufbereitungseinheit der zuvor erwähnten Filterstrangherstellungsvorrichtung so angeordnet sein, dass dort der Transport des Filtertowstreifens etwa in horizontaler oder vertikaler Richtung stattfindet. Bei einer bevorzugten Weiterbildung dieser Ausführung ist die Aufbereitungseinheit so angeordnet, dass der Transport des Filtertowstreifens durch diese Aufbereitungseinheit in einem stromaufwärts gelegenen Abschnitt etwa in vertikaler Richtung und in einem stromabwärts gelegenen Abschnitt etwa in horizontaler Richtung stattfindet. Eine solche Anordnung erweist sich als besonders Platz sparend.In a further development of this embodiment, at least a portion of the processing unit of the aforementioned filter-strand production device can be arranged such that there the transport of the filter tow-strip takes place approximately in the horizontal or vertical direction. In a preferred development of this embodiment, the processing unit is arranged such that the transport of the filter tow strip through this processing unit takes place in an upstream section approximately in the vertical direction and in a downstream section approximately in the horizontal direction. Such an arrangement proves to be particularly space-saving.
Für eine Platz sparende Anordnung sollte die zusätzliche Aufbereitungseinheit zur Aufbereitung des zusätzlichen Filtertowstreifens oberhalb der Filterstrangherstellungsvorrichtung zur Herstellung der mit Papier umhüllten inneren Seele angeordnet sein.For a space-saving arrangement, the additional processing unit for processing the additional filter tow strip should be located above the filter rod manufacturing apparatus for producing the paper wrapped inner core.
Bevorzugt kann auch mindestens ein Abschnitt dieser zusätzlichen Aufbereitungseinheit so angeordnet sein, dass dort der Transport des zusätzlichen Filtertowstreifens etwa in horizontaler oder vertikaler Richtung stattfindet.Preferably, at least a portion of this additional processing unit may be arranged so that there takes place the transport of the additional filter tow strip approximately in the horizontal or vertical direction.
Dabei ist es grundsätzlich unerheblich, ob die Aufbereitung des ersten Filtertowstreifens in der oberen Aufbereitungseinheit und die Aufbereitung des zweiten Filtertowstreifens in der unteren Aufbereitungseinheit stattfindet oder umgekehrt.It is fundamentally irrelevant whether the preparation of the first filter tow strip in the upper processing unit and the processing of the second filter tow strip in the lower processing unit takes place or vice versa.

In den Figuren sind nur schematisch und zum Teil in Einzelheiten Komponenten, Module und Vorrichtungen und eine diese enthaltende Anlage gemäß der Erfindung zur Herstellung von Koaxialfiltern für stabförmige Rauchartikel wie insbesondere Zigaretten im Strangverfahren dargestellt, wobei die Figuren jeweils nur im Wesentlichen die für das Verständnis der Erfindung erforderlichen Teile und Komponenten zeigen. Im Maschinenbau übliche Bestandteile der Maschine oder Vorrichtung, wie beispielsweise Einzelheiten eines Gestells sowie von Halterungen, Lagerungen und Verkleidungen, sind in den Zeichnungen im Interesse ihrer besseren Überschaubarkeit im Wesentlichen nicht dargestellt. Außerdem ist in den Figuren die Verarbeitungs- und Transportrichtung von rechts nach links orientiert.In the figures, only schematically and in part in detail components, modules and devices and a plant containing them according to the invention for the production of coaxial filters for rod-shaped smoking articles such as in particular cigarettes in the strand process are shown, wherein the figures only in each case only substantially for the understanding of Invention required parts and components show. Components of the machine or device which are customary in mechanical engineering, such as, for example, details of a frame and of holders, supports and coverings, are essentially not shown in the drawings for the sake of better clarity.

Bei der ersten Aufbereitungseinheit 4 und der nachgeschalteten Einstrang-Maschine 10 handelt es sich um herkömmliche Komponenten, die gemeinsam die Filterstrangherstellungsvorrichtung 2 bilden, bei der es sich um eine herkömmliche Einstrang-Anlage zur Herstellung von einfachen, also einlagigen Filtersträngen oder Filterstäben handelt.The
Erfindungsgemäß wird eine solche herkömmliche Filterstrangherstellungsvorrichtung 2 nun zur Herstellung einer mit Papier umhüllten inneren Seele für die Bildung von Koaxialfiltern eingesetzt. Hierzu ist es erforderlich, dass die Einstrang-Maschine 10 den Filterstrang 12 als Endlosstrang durch ihre auslassseitige Schnittstelle 10a abgibt. Während in einer herkömmlichen Einstrang-Anlage die Filterstäbe in geschnittenen Längen ausgegeben werden, ist im vorliegenden Fall eine Schnittfunktion nicht erwünscht. Deshalb muss eine eventuell in der Einstrang-Maschine 10 vorhandene Schneideeinrichtung abgeschaltet oder deinstalliert werden oder in der Einstrang-Maschine 10 von vornherein eine Schneideeinrichtung nicht vorgesehen sein. Im Übrigen handelt es sich aber bei der ersten Aufbereitungseinheit 4 und der Einstrang-Maschine 10 um herkömmliche Komponenten, die in der Regel zur Bildung einer im Wesentlichen vollständigen Einstrang-Anlage zur Herstellung von einfachen, also einlagigen Filtersträngen oder Filterstäben verwendet werden.According to the invention, such a conventional filter

An der stromabwärts befindlichen Seite der Anordnung aus der Filterstrangherstellungsvorrichtung 2 und der darüber liegenden zweiten Aufbereitungseinheit 14 ist eine Vorrichtung 18 vorgesehen, die für die Herstellung von Koaxialfiltern spezifische Funktionen übernimmt und nachfolgend als Übergangsmodul bezeichnet wird. In diesem Übergangsmodul 18 werden in nachfolgend noch näher beschriebener Weise der als innere Seele vorgesehene Filterstrang 12, der in der Einstrang-Maschine 10 mit Papier umhüllt worden ist und durch die auslassseitige Schnittstelle 10a der Einstrang-Maschine 10 ausgegeben wird, und der durch die auslassseitige Schnittstelle 14a der oberen zweiten Aufbereitungseinheit 14 ausgegebene zweite Filtertowstreifen 16 zu einem gemeinsamen Koaxialfilterstrang zusammengeführt.On the downstream side of the arrangement of the filter
Für den Transport des Filterstranges 12 und des zweiten Filtertowstreifens 16 durch das Übergangsmodul 18 sind im Übergangsmodul 18 eine entsprechende Filterstrangbahn und eine entsprechende Towführungsbahn vorgesehen, die jedoch in den
Die Filterstrangbahn und die Towführungsbahn laufen innerhalb des Übergangsmoduls 18 in Richtung auf eine Umhüllungseinrichtung 22 zusammen, die ebenfalls im Übergangsmodul 18 enthalten ist. In der Umhüllungseinrichtung 22 wird der Filterstrang 12, der bereits in der Einstrang-Maschine 10 der vorgeschalteten Filterstrangherstellungsvorrichtung 2 rundgeformt und mit Umhüllungspapier umwickelt worden ist, mit dem zweiten Filtertowstreifen 16 umhüllt. Hierzu soll der zweite Filtertowstreifen 16 in einer im Wesentlichen ausgebreiteten Form oder gegebenenfalls in einer quer zu seiner Längserstreckung leicht gekrümmten Form die Umhüllungseinrichtung 22 erreichen. Deshalb ist eine Rundformung des zweiten Filtertowstreifens 16 in der zweiten Aufbereitungseinheit 14 nicht vorgesehen.The filter strand web and the tow guide run together within the
Nicht zuletzt dadurch, dass die zweite Aufbereitungseinheit 14 über der Filterstrangherstellungsvorrichtung 2 liegt, wird bei der Ausführung gemäß
Es ist aber auch denkbar, dass bei Bedarf die Relativanordnung des zweiten Filtertowstreifens 16 gegenüber dem Filterstrang 12 im Bereich des Einlasses der Umhüllungseinrichtung 22 vertauscht ist, so dass der rundgeformte und mit Umhüllungspapier versehene Filterstrang 12 mit dem im Wesentlichen flach ausgebreiteten zweiten Filtertowstreifen 16 von unten eingehüllt wird. Eine solche modifizierte Ausführung ist beispielhaft in
Demgegenüber verläuft in den dargestellten Ausführungsbeispielen gemäß den
Die Umhüllungseinrichtung 22 weist einen Einlauf- oder Umhüllungsfinger 30 auf, der in
Der so hergestellte Koaxialfilterstrang 32 tritt aus der Umhüllungseinrichtung 22 durch einen Auslass 22a aus und wird dann in eine nachgeschaltete Strangmaschine 34 gefördert. Der Auslass 22a der Umhüllungseinrichtung 22 bildet gleichzeitig eine auslassseitige Schnittstelle für das Übergangsmodul 18 und muss für eine reibungslose Übergabe des Koaxialfilterstranges hinsichtlich Positionierung und Ausrichtung mit einer einlassseitigen Schnittstelle 34a der Strangmaschine 34 entsprechend übereinstimmen. Auch diese Schnittstellen sind bevorzugt mit entsprechenden Durchgangsöffnungen zur Durchführung des Koaxialfilterstranges versehen.The
Während für die Herstellung des Koaxialfilterstranges 32 der Filterstrang 12 zur Bildung der inneren Seele und der Zwischenlage aus Umhüllungspapier sowie der zweite Filtertowstreifen 16 getrennt voneinander produziert werden und zur Verfügung stehen müssen und somit eine entsprechend zweibahnige Herstellung und Aufbereitung stromaufwärts vor dem Übergangsmodul 18 erforderlich ist, bildet der stromabwärts aus dem Übergangsmodul 18 austretende Koaxialfilterstrang 32 nur einen einzigen Strang, der entlang einer Bahn in der nachgeschalteten Strangmaschine 34 fortzubewegen und weiterzuverarbeiten ist. Während seiner Bewegung durch die Strangmaschine 34 wird der Koaxialfilterstrang 32 den gleichen weiteren Bearbeitungsschritten unterworfen, wie es auch der Fall mit einem einfachen Filterstrang ist, zu dessen Weiterverarbeitung die Strangmaschine 34 in herkömmlicher Weise eingesetzt würde. Hierbei wird der Köaxialfilterstrang 32 insbesondere mit einem Hüllmaterialstreifen insgesamt umhüllt, wodurch die Außenseite der vom zweiten Filtertowstreifen 16 gebildeten äußeren Lage mit Umhüllungspapier abgedeckt wird, und anschließend in Filterstäbe zerschnitten. Die hierfür verwendeten Bearbeitungseinrichtungen sind zwar teilweise schematisch in den
Wie aus der vorangegangenen Beschreibung ersichtlich wird, findet für die nachgeordnete Weiterverarbeitung des Koaxialfilterstranges 32 ebenfalls eine herkömmliche Strangmaschine Verwendung, die im Wesentlichen keinerlei Modifikationen oder Adaptionen bedarf.As can be seen from the preceding description, a conventional stranding machine, which requires essentially no modifications or adaptations, is also used for the downstream further processing of the
