Die Erfindung beruht auf dem Gedanken, dass im Austrittsbereich einer Auftragseinrichtung, insbesondere im Austrittsbereich des Gehäuses der Auftragseinrichtung, vom geförderten Streifen aus Filtermaterial mitgerissene Partikel und/oder Flusen in der Umgebungsluft vom mit Triacetin getränkten Streifen entfernt werden, wodurch die Aufnahme der ebenfalls mit Triacetin getränkten Flusen in den Streifen vermieden wird, da durch die mit Triacetin getränkten Flusen bei der Weiterverarbeitung des Filtermaterialstreifens Schmelzlöcher (melt holes) in den daraus hergestellten Filtern entstehen können. Hierdurch werden Flusenansammlungen am Austritt oder im Austrittsbereich der Auftragseinrichtung bzw. Sprühkammer vermieden, wobei die Absaugung der Umgebungsluft beidseits des Filtermaterialstreifens erfolgt.The invention is based on the idea that in the exit region of an application device, in particular in the exit region of the housing of the applicator, entrained particles and / or fluff from the conveyed strip of filter material in the ambient air are removed from the triacetin-impregnated strip, whereby the recording of the likewise with triacetin soaked lint in the strip is avoided, as caused by the laced with triacetin fluff in the further processing of the filter material strip melt holes in the filters produced therefrom can. As a result, lint accumulations are avoided at the outlet or in the outlet region of the applicator or spray chamber, wherein the extraction of the ambient air takes place on both sides of the filter material strip.
Erfindungsgemäß wird der Filtermaterialstreifen, insbesondere zwischen der Oberkante und der Unterkante der seitlich angeordneten Ansaugöffnungen, hindurchgeführt, um Flusen aus den, insbesondere seitlichen, Bereichen des Austritts des Filtermaterialstreifens am Ausgang der Sprühkammer zu entfernen. Die Absaugung der angesammelten Flusen erfolgt dabei seitlich und damit quer zur Förderrichtung des Filtermaterialstreifens in der Förderstrecke, in der die Auftragseinrichtung, vorzugsweise mit ihrem Gehäuse, angeordnet ist. Insbesondere erfolgt die Absaugung der Umgebungsluft mit den Flusen im unmittelbaren Anschluss an die Auftragseinrichtung bzw. deren Gehäuse im Bereich des Austrittsspalts des Gehäuses und damit noch innerhalb der Förderstrecke des Filtermaterialstreifens zwischen zwei Walzenpaaren, durch die die Förderstrecke bzw. die Auftragsstrecke mit der Auftragseinrichtung ausgebildet bzw. begrenzt ist.According to the invention, the filter material strip, in particular between the upper edge and the lower edge of the laterally arranged suction openings, is guided in order to remove lint from the, in particular lateral, areas of the outlet of the filter material strip at the outlet of the spray chamber. The suction of the accumulated lint takes place laterally and thus transversely to the conveying direction of the filter material strip in the conveying path, in which the applicator, preferably with its housing, is arranged. In particular, the extraction of the ambient air with the lint takes place immediately after the application device or its housing in the region of the outlet gap of the housing and thus within the conveying path of the filter material strip between two pairs of rollers through which the conveying path or the application path is formed with the application device is limited.
Im Rahmen der Erfindung ist auch denkbar, dass jeweils eine Ansaugöffnung zum Ansaugen der Umgebungsluft oberhalb und gleichzeitig jeweils eine Ausgangsöffnung unterhalb des geförderten Streifens im Anschluss an die Auftragseinrichtung angeordnet sind, so dass die Umgebungsluft von der Oberseite und von der Unterseite des Streifens angesaugt wird.In the context of the invention it is also conceivable that in each case an intake opening for sucking the ambient air above and at the same time each an exit opening below the conveyed strip are arranged following the applicator, so that the ambient air is sucked in from the top and from the bottom of the strip.
Darüber hinaus wird die Einrichtung dadurch weitergebildet, dass bezogen auf die Förderrichtung des Streifens nach der Auftragseinrichtung und/oder im Austrittsbereich des Streifens aus der Auftragseinrichtung eine Saugeinrichtung, vorzugsweise mit zwei seitlichen Ansaugöffnungen, mit einer Flusenabscheidekammer verbunden ist, wobei insbesondere die Saugeinrichtung mit zwei Ansaugöffnungen vorgesehen ist, zwischen denen der aus der Auftragseinrichtung austretende Streifen gefördert wird oder förderbar ist.In addition, the device is further developed in that, based on the conveying direction of the strip after the application device and / or in the exit region of the strip from the application device a suction device, preferably with two lateral suction openings, is connected to a lint separating chamber, wherein in particular the suction device is provided with two suction openings, between which the strip emerging from the application device is conveyed or conveyed.
Gemäß der Erfindung wird Umgebungsluft im Bereich des geförderten Streifens durch die Saugeinrichtung abgesaugt, so dass herumfliegende Triacetin haltige Flusen aus dem Förderbereich des Streifens entfernt werden und anschließend die Flusen in der abgesaugten Umgebungsluft in einer Flusenabscheidekammer oder -vorrichtung abgeschieden werden.According to the invention, ambient air in the area of the conveyed strip is sucked by the suction device, so that flying lint that contains flying triacetin are removed from the conveying area of the strip, and then the lint in the extracted ambient air is deposited in a lint separation chamber or device.
Hierbei beruht der alternative Gedanke bzw. der weitere Gedanke der Erfindung darauf, dass die vom geförderten Filtermaterialstreifen mitgerissenen Flusen und/oder Partikel in der Umgebungsluft des Streifens nach ihrer Entfernung durch Ansaugen mittels der Saugeinrichtung aus der Umgebung des Filtermaterialstreifens einer Abscheidevorrichtung bzw. einer Abscheidekammer zugeführt werden, in der die Flusen und ggf. auch die Partikel aus der mit Triacetintröpfchen kontaminierten bzw. angereicherten Umgebungsluft abgeschieden werden, so dass die von Flusen befreite bzw. von Partikeln befreite Umgebungsluft anschließend in weiteren Aufbereitungsprozessen von Triacetin befreit wird und das gewonnene Triacetin aus der Umgebungsluft zur Besprühung des Filtermaterialstreifens bereitgestellt wird.Here, the alternative idea or the further idea of the invention is based on the fact that the lint and / or particles entrained by the conveyed filter material strip in the ambient air of the strip are supplied to a separation device or a deposition chamber after removal by suction by means of the suction device from the surroundings of the filter material strip be in which the lint and possibly also the particles from the contaminated with Triacetintröpfchen or enriched ambient air are deposited, so that the liberated from lint and freed from particles ambient air is then freed from triacetin in further treatment processes and recovered triacetin from the Ambient air is provided for spraying the strip of filter material.
Gemäß einer Weiterbildung wird ferner vorgeschlagen, dass die Ansaugöffnungen der Saugeinrichtung oder die Ansaugöffnungen der Saugeinrichtungen mit ihren Ansaugflächen schräg entgegengesetzt, d.h. nicht parallel zur Förderrichtung des Streifens, ausgerichtet sind. Hierdurch wird eine Abführung der Umgebungsluft, in der die mit Triacetin getränkten Flusen und Triacetintröpfchen sich befinden bzw. schweben, erreicht, wobei aufgrund der Förderung des Streifens durch die Auftragseinrichtung die Flusen und die Triacetin haltige Luft außerhalb des Gehäuses der Auftragseinrichtung im unmittelbaren Anschluss an die Auftragseinrichtung oberseitig und unterseitig bzw. an beiden Seiten des Materialstreifens durch Ansaugen bzw. Absaugen entfernt werden.According to a further development, it is also proposed that the suction openings of the suction device or the suction openings of the suction devices are aligned with their suction surfaces obliquely opposite, ie not parallel to the conveying direction of the strip. As a result, a discharge of the ambient air, in the the lint and triacetin droplets soaked with triacetin are reached, the lint and triacetin containing air outside the applicator housing immediately following the applicator, on the top, bottom and both sides due to the conveyance of the strip by the applicator of the strip of material are removed by suction or suction.
Dazu ist es weiter vorteilhaft, wenn auf beiden Seiten bzw. Schmalseiten bzw. seitlich vom zu fördernden oder geförderten Streifen jeweils ein Ansaugstutzen mit jeweils einer ausgebildeten Ansaugöffnung angeordnet ist.For this purpose, it is further advantageous if in each case an intake manifold, each with a formed suction opening is arranged on both sides or narrow sides or laterally of the conveyed or conveyed strip.
Dazu ist weiter vorgesehen, dass die Ansaugstutzen seitlich, vorzugsweise seitlich nach außen, und/oder bezogen auf die Förderebene des Streifens, vorzugsweise in der Förderstrecke, nach unten geneigt ausgerichtet sind und/oder dass die Ansaugstutzen geradlinig ausgebildet sind.For this purpose, it is further provided that the intake manifold laterally, preferably laterally outwardly, and / or relative to the conveying plane of the strip, preferably in the conveying path, are inclined downwards and / or that the intake manifolds are formed in a straight line.
Überdies zeichnet sich eine Weiterbildung der Einrichtung dadurch aus, dass die Ansaugstutzen unterdruckseitig in einer gemeinsamen Flusenabscheidekammer münden oder mit einer gemeinsamen Flusenabscheidekammer verbunden sind. Durch die geradlinige Ausbildung der Ansaugstutzen werden die Flusen aus der Umgebungsluft ohne Umlenkungen direkt in eine gemeinsame Flusenabscheidekammer bzw. Flusenabscheidevorrichtung durch den angelegten Unterdruck gefördert, so dass Flusen und/oder Partikel aus der angesaugten Umgebungsluft in der Abscheidevorrichtung bzw. - kammer abgeschieden werden.Moreover, a development of the device is characterized in that the intake manifold open on the negative pressure side in a common Flusenabscheidekammer or are connected to a common Flusenabscheidekammer. Due to the rectilinear design of the intake, the fluff from the ambient air without deflections are conveyed directly into a common Flusenabscheidekammer or Flusenabscheidevorrichtung by the applied negative pressure, so that lint and / or particles from the sucked ambient air in the separator or - chamber are deposited.
Für die weitere Aufbereitung der von Flusen befreiten Umgebungsluft aus der Abscheidekammer ist weiter vorgesehen, dass die Flusenabscheidekammer auf der Unterdruckseite mit einer, vorzugsweise ersten, Flüssigkeitsabscheidekammer bzw. Flüssigkeitsabscheidevorrichtung, insbesondere Triatcetinabscheidekammer, verbunden ist, wobei insbesondere die Flusenabscheidekammer und die Flüssigkeitsabscheidekammer mittels einer Durchbrechung in einer Trennwand zwischen den beiden Kammern miteinander verbunden sind.For the further treatment of the liberated from fluff ambient air from the deposition chamber is further provided that the Flusenabscheidekammer on the negative pressure side with a, preferably first, Flüssigkeitsabscheidekammer or Flüssigkeitsabscheidevorrichtung, in particular Triatcetinabscheidekammer is connected, in particular the Flusenabscheidekammer and Flüssigkeitsabscheidekammer are interconnected by means of an opening in a partition wall between the two chambers.
Für die weitere Aufbereitung der abgesaugten und Triacetin haltigen Umgebungsluft ist außerdem vorgesehen, dass die Flüssigkeitsabscheidekammer bzw. -vorrichtung mit einer zweiten Flüssigkeitsabscheidevorrichtung, insbesondere mit einem Demister bzw. Drahtgeflecht, verbunden ist. Durch die zweistufige Abscheidung wird ein hoher Reinigungsgrad der angesaugten Umgebungsluft erreicht und gleichzeitig eine große rückgewonnene Menge an Triacetin einem Triacetinreservoir zugeführt, das beispielsweise mit einer Sprühdüse oder dergleichen mit der Auftragseinrichtung verbunden ist und wodurch der Filtermaterialstreifen mit Triacetin beaufschlagt wird.For the further treatment of the extracted and triacetin-containing ambient air is also provided that the Flüssigkeitsabscheidekammer or device with a second Flüssigkeitsabscheidevorrichtung, in particular with a demister or wire mesh, is connected. By the two-stage deposition, a high degree of purification of the sucked ambient air is achieved and at the same time a large amount of triacetin fed back to a triacetin reservoir, which is connected, for example with a spray nozzle or the like with the applicator and whereby the strip of filter material is charged with triacetin.
Darüber hinaus ist es in einer vorteilhaften Ausgestaltung vorgesehen, dass die Ansaugstutzen in ihren seitlichen Positionen zum Streifen verschiebbar ausgebildet sind, so dass der Abstand zwischen zwei, insbesondere sich gegenüberliegend angeordneten, Ansaugstutzen einstellbar ist. Zwischen den beiden Ansaugstutzen wird der mit Triacetin versehene Streifen durchgeführt. Hierbei ist es bevorzugt, dass der aus der Auftragseinrichtung austretende und mit Triacetin versehene Filtermaterialstreifen zwischen der Oberkante und der Unterkante der Ansaugstutzen einer vorbestimmten Förderebene in der Auftragsstrecke hindurchgeführt wird.Moreover, it is provided in an advantageous embodiment that the intake manifold are designed to be displaceable in their lateral positions to the strip, so that the distance between two, in particular arranged opposite, intake manifold is adjustable. Between the two intake manifold, the strip provided with triacetin is carried out. In this case, it is preferable for the strip of filter material emerging from the application device and provided with triacetin to be passed between the upper edge and the lower edge of the intake connection of a predetermined conveying plane in the application path.
Außerdem zeichnet sich eine Ausführungsform der Einrichtung dadurch aus, dass die abgesaugte und, vorzugsweise in einer Flusenabscheidekammer, von Flusen befreite, und vorzugsweise in einer Flüssigkeitsabscheidekammer um eine Flüssigkeit abgemagerte, Umgebungsluft mittels eines Gebläses in die Umgebung einer die Auftragseinrichtung aufweisenden Vorrichtung, insbesondere Maschine der Tabak verarbeitenden Industrie, druckseitig abgebbar ist oder abgegeben wird, wobei insbesondere die von Flusen befreite, und vorzugsweise um eine Flüssigkeit abgemagerte, Umgebungsluft mit aus einer Frischluftquelle abgebbaren Frischluft mischbar ist oder gemischt wird.In addition, an embodiment of the device characterized thereby that the extracted and, preferably in a Flusenabscheidekammer, freed from lint, and preferably emaciated in a Flüssigkeitsabscheidekammer to a liquid, ambient air by means of a blower in the environment of a applicator device having apparatus, in particular machine of the tobacco processing industry, the pressure side abgabbar or in particular, the liberated from lint, and preferably emaciated by a liquid, ambient air is mixed with deliverable from a fresh air source fresh air or mixed.
Darüber hinaus wird die Aufgabe gelöst durch ein Verfahren zum Aufbereiten eines, insbesondere geförderten, Streifens aus Filtermaterial der Tabak verarbeitenden Industrie, insbesondere Filtertowstreifen, entlang einer Förderstrecke, wobei mittels einer Auftragseinrichtung, vorzugsweise in einem Gehäuse der Auftragseinrichtung, ein, vorzugsweise flüssiger, Zusatzstoff auf den Streifen aufgebracht wird, das dadurch weitergebildet wird, dass nach Aufbringen des Zusatzstoffes, insbesondere nach Austritt des Streifens aus der Auftragseinrichtung bzw. aus dem Gehäuse der Auftragseinrichtung, aus der Umgebung des geförderten Streifens, vorzugsweise seitlich, über zwei Ansaugöffnungen Flusen und/oder Partikel in der Umgebungsluft des Streifens abgesaugt werden und dass aus der Umgebung des geförderten Streifens entfernte, insbesondere abgesaugte, Flusen in einer Flusenabscheidekammer abgeschieden werden.Moreover, the object is achieved by a method for processing a, in particular promoted, strip of filter material of the tobacco processing industry, in particular filter tow, along a conveying path, wherein by means of an applicator, preferably in a housing of the applicator, a, preferably liquid, additive the strip is applied, which is further developed by the fact that after application of the additive, in particular after exit of the strip from the applicator or from the housing of the applicator, from the environment of the conveyed strip, preferably laterally, via two suction lint and / or particles be sucked in the ambient air of the strip and that removed from the environment of the subsidized strip removed, in particular sucked, lint are deposited in a Flusenabscheidekammer.
Hierdurch werden Flusen am Ausgang der Auftragseinrichtung bzw. einer Sprühkammer abgesaugt und/oder die abgesaugten Flusen aus der Umgebung des geförderten Filtermaterialstreifens aus der angesaugten Umgebungsluft abgetrennt, wobei es ferner möglich ist, auch die mit Triacetin als Zusatzstoff kontaminierte Umgebungsluft um den Zusatzstoff abzumagern.As a result, lint be sucked at the output of the applicator or a spray chamber and / or separated the extracted lint from the environment of the funded filter material strip from the sucked ambient air, and it is also possible, even with triacetin as an additive contaminated ambient air to degrade the additive.
Dazu ist in einer Weiterbildung des Verfahrens vorgesehen, dass die abgesaugte und von Flusen befreite bzw. abgemagerte Umgebungsluft einer ersten Flüssigkeitsabscheidekammer bzw. -abscheidevorrichtung zugeführt wird, wobei insbesondere die Umgebungsluft aus der ersten Flüssigkeitsabscheidekammer nachfolgend einer zweiten Flüssigkeitsabscheidekammer zugeführt wird. Dadurch wird eine zuverlässige Rückgewinnung von Triacetin aus der abgesaugten Luft erreicht.For this purpose, it is provided in a development of the method that the aspirated and freed of lint or emptied ambient air of a first Flüssigkeitsabscheidekammer or -abscheidevorrichtung is supplied, wherein in particular the ambient air from the first Flüssigkeitsabscheidekammer is subsequently supplied to a second Flüssigkeitsabscheidekammer. This ensures reliable recovery of triacetin from the extracted air.
Des Weiteren ist es in einer Ausgestaltung vorteilhaft, wenn die Absaugung der Flusen und/oder Partikel enthaltenden Umgebungsluft nach dem Start oder während des Starts des Aufbereitungsprozesses, insbesondere an einer Maschine, eingeschaltet und/oder vor dem Ende oder am Ende des Aufbereitungsprozesses, d.h. vor oder bei einem Maschinenstopp, ausgeschaltet wird.Furthermore, in one embodiment, it is advantageous if the extraction of ambient air containing lint and / or particles is switched on after the start or during the start of the treatment process, in particular on a machine, and / or before the end or end of the treatment process, i. before or at a machine stop, is switched off.
Des Weiteren ist es vorteilhaft, wenn der Streifen im Bereich des Wirkungsbereichs der Absaugung der Flusen und/oder Partikel enthaltenden Umgebungsluft mit Blasluft beaufschlagt wird, so dass durch im Förderbereich des Streifens angeordnete Blasluftdüsen im Bereich des Austritts des Streifens an der Auftragungseinrichtung Flusen und Partikel weggeblasen werden, wobei die Richtung der Blasluftdüsen bevorzugterweise derart eingestellt ist, dass die weggeblasenen Flusen in Richtung der Ansaugstutzen bzw. der Ansaugöffnungen bewegt werden.Furthermore, it is advantageous if blown air is applied to the strip in the region of the effective region of the extraction of ambient air containing lint and / or particles, so that lint and particles are blown away from the application device by blowing air nozzles arranged in the conveying region of the strip are, wherein the direction of the Blasluftdüsen is preferably set such that the blown lint are moved in the direction of the intake manifold or the intake ports.

Über ein Umlenkblech 19 gelangt der Filtertowstreifen 2 in die Vorreckstrecke 4, die einerseits von einem Walzenpaar 21 mit den Walzen 22, 23, andererseits von einem Walzenpaar 24 mit motorisch angetriebenen Walzen 26, 27 begrenzt ist. Die Walzen 22, 23 werden vom Towstreifen geschleppt, d.h. sie laufen mit mehr oder weniger Widerstand leer. Wenn erforderlich, können sie motorisch angetrieben werden. Sie können auch in einer an sich bekannten Weise mit steuerbarer Kraft gegeneinander gedrückt werden. In der Vorreckstrecke 4, in der der Streifenabschnitt schräg nach unten gefördert wird, wird das Filtertow 2 vorgereckt.Via a

Die Walzenpaare 24 und 39 bilden somit die eigentliche Reckeinrichtung. Die Walzen 26 und 41 weisen eine starre, gerillte Oberfläche auf, die jeweils eine nachgiebige Oberfläche der Walzen 27 bzw. 42 berühren. Derartige Walzenkonfigurationen sind durch die vorerwähnten Filtertow-Aufbereitungsgeräte AF 2, AF 3 und AF 4 der Anmelderin bekannt und z.B. in
