Description

Die Erfindung betrifft ein Verfahren und eine Einrichtung zum Zuführen eines, vorzugsweise flüssigen, Zusatzstoffes auf eine bewegte, ausgebreitete Bahn aus Filtermaterial der tabakverarbeitenden Industrie mittels wenigstens eines Auftragsorgans, wobei der Zusatzstoff über eine Auftragsfläche zugeführt wird oder zuführbar ist. Ferner betrifft die Erfindung eine Vorrichtung zum Herstellen von Filterstäben für stabförmige Artikel der tabakverarbeitenden Industrie.The invention relates to a method and a device for supplying a, preferably liquid, additive to a moving, spread web of filter material of the tobacco processing industry by means of at least one applicator member, wherein the additive is supplied via an application surface or can be fed. Furthermore, the invention relates to an apparatus for producing filter rods for rod-shaped articles of the tobacco processing industry.

Bei der Herstellung von Filterstäben für die tabakverarbeitende Industrie wird Filtertow, das meist aus Celluloseacetat besteht, als endloser Streifen von einem Vorrat abgezogen und behandelt. Das Filtertow besteht aus einem Gewebe aus locker aneinander haftenden Fäden, die zur Bildung einer breiten und meist ebenen Bahn auseinandergezogen werden, so daß die Fäden nebeneinander und im wesentlichen parallel bewegt werden. Die Ausbreitung der Bahn erfolgt in einer Ausbreiterdüse. Nach der Ausbreitung wird der Bahn ein Zusatzstoff, der meist flüssig ist und z.B. aus Triacetin-Tröpfchen besteht, in fein verteilter Form zugeführt. Die Tröpfchen lösen die Fäden an, so daß die Fäden nach ihrer Zusammenfassung zu einem runden Strang und Umhüllung mit einem Filterpapierstreifen in einer Filterstrangmaschine dauerhaft aneinander haftend, d.h. vernetzt werden. Anstelle eines flüssigen Zusatzstoffes kann auch ein aus einer fein verteilten pulverförmigen Substanz bestehender Zusatzstoff verwendet werden. Aufbereitungsgeräte der vorbeschriebenen Art sind in den Patentschriften US 5 060 664 und US 4 511 420 beschrieben.In the production of filter rods for the tobacco processing industry Filter Tov, which consists mostly of cellulose acetate, withdrawn from a supply as an endless strip and treated. The filter tow consists of a fabric of loosely adhering threads, which are pulled apart to form a broad and mostly flat web, so that the threads are moved side by side and substantially parallel. The propagation of the web takes place in a spreader nozzle. After spreading, the web is fed an additive, which is usually liquid and consists for example of triacetin droplets, in finely divided form. The droplets dissolve the threads, so that the threads after their summary to a round strand and wrapping with a filter paper strip in a filter rod machine permanently adhering to each other, that are networked. Instead of a liquid additive, an additive consisting of a finely divided powdery substance can also be used. Processing equipment of the type described above are in the patents US 5 060 664 and US 4 511 420 described.

Aus der Offenlegungsschrift DE-A-199 59 034 ist bekannt, Filtertow mit einer quer zur Bewegungsrichtung des Filtertows angeordneten Reihe von Düsen mit Weichmacher zu besprühen. Hierbei werden die einzelnen Düsen mittels vorgeordneten, die Dichte des Filtertows in den betreffenden Abschnitten erfassenden Sensoren gesteuert.From the publication DE-A-199 59 034 It is known to spray filter tow with a transverse to the direction of movement of the filter tow row of nozzles with plasticizer. Here, the individual nozzles are controlled by upstream, the density of the filter tow in the sections concerned sensors.

Von großer Wichtigkeit für die Qualität der Aufbereitung ist die gute Vereinzelung der einzelnen Fäden oder Fasern und/oder ein gleichmäßiger Auftrag von fein verteilten Weichmacherteilchen in Form von Tröpfchen oder Feinpartikeln.Of great importance for the quality of the treatment is the good separation of the individual threads or fibers and / or a uniform application of finely divided plasticizer particles in the form of droplets or fine particles.

In DE-A-28 52 948 ist eine Vorrichtung für die Aufbringung einer Zwischenfaser-Bindemittelflüssigkeit auf ein Faserband beschrieben, wobei die Aufbringung mittels einer Sprüheinrichtung zum Versprühen der Bindemittelflüssigkeit in einer Kammer gegen das über eine Transporteinrichtung laufende Faserband erfolgt. Im Inneren eines Gehäuses sind zwischen der Sprüheinrichtung und einem Zylinder Blenden zur Begrenzung eines Aufsprühbereichs in der Zone seitlich angeordnet, in der das Faserband mit dem Zylinder in Kontakt steht. Die Blenden sind einstellbar ausgebildet, um den Bereich der Zone zu begrenzen, in der das Band mit dem Bindemittel besprüht wird.In DE-A-28 52 948 a device for the application of an intermediate fiber binder liquid is described on a sliver, wherein the application by means of a spraying device for spraying the binder liquid in a chamber against the running through a transport means sliver takes place. In the interior of a housing, shutters for limiting a spraying area in the zone are provided between the spraying device and a cylinder arranged in which the sliver is in contact with the cylinder. The apertures are adjustable to limit the area of the zone where the tape is sprayed with the binder.

Die der Erfindung zugrunde liegende Aufgabe besteht darin, das Filtermaterial gleichmäßig mit einem Zusatzstoff zu versehen, wobei es möglich sein soll, die Auftragsmenge des Zusatzstoffes auf einfache Weise an die jeweilige Anwendung bzw. das Filtermaterial anzupassen, und wobei der Verbrauch an Zusatzstoff gering gehalten werden kann und der Zusatzstoff fein dosiert aufgetragen werden kann.The object underlying the invention is to provide the filter material uniformly with an additive, wherein it should be possible to easily adjust the application rate of the additive to the respective application or the filter material, and wherein the consumption of additive are kept low can and the additive can be applied finely dosed.

Gemäß der Erfindung wird dies dadurch erreicht, daß die Größe der Auftragsfläche mittels eines verfahrbaren Abdeckelements eingestellt wird. Die Erfindung beruht auf dem Gedanken, daß die Auftragsmenge des Zusatzstoffes an das Filtermaterial bzw. an den herzustellenden Filter angepaßt werden kann. Dabei wird unter dem Begriff "Auftragsfläche" insbesondere die Fläche eines (offenen) Bereiches verstanden, innerhalb dessen der Zusatzstoff auf das am Bereich vorbeigeführte Filtermaterial aufgetragen wird. Hierbei ist erfindungsgemäß vorgesehen, daß die Größe dieser Fläche vorbestimmt und variiert werden kann.According to the invention, this is achieved in that the size of the application surface is adjusted by means of a movable cover member. The invention is based on the idea that the order quantity of the additive can be adapted to the filter material or to the filter to be produced. In this case, the term "application surface" is understood in particular to mean the surface of an (open) region within which the additive is applied to the filter material conducted past the region. Here, the invention provides that the size of this area can be predetermined and varied.

Durch die Variabilität der Auftragsfläche ist es möglich, sowohl die Auftragsmenge zu dosieren als auch den Verbrauch an Zusatzstoff zu senken, da der Überschuß an vom Filtermaterial nicht aufgenommenen Zusatzstoffs herabgesetzt wird.Due to the variability of the application surface, it is possible to both dose the order amount and to reduce the consumption of additive, since the excess is reduced by the filter material not absorbed additive.

Gemäß einer vorteilhaften Ausgestaltung der Erfindung wird die Auftragsfläche, insbesondere mittels wenigstens eines Abdeckelements, verändert, so daß bspw. durch Verfahren des Abdeckelements eine Anpassung der Auftragsfläche, an die gewünschte Auftragsmenge und/oder an die Breite des Filtermaterialstreifens einfach und schnell erzielt wird. Eine Trockenfilterentnahme kann bspw. durch ein vollständiges Schließen oder Abschotten der Auftragsfläche vorgenommen werden. In diesem Fall hat die Auftragsfläche die Größe Null. Als Trockenfilter werden Filter ohne Zusatzstoff verstanden. Gleichzeitig kann eine Förderung des Zusatzstoffes erfolgen, wobei der Zusatzstoff durch die Abschottung nicht auf das Filtermaterial appliziert wird.According to an advantageous embodiment of the invention, the application surface, in particular by means of at least one cover, changed so that, for example. By moving the cover an adjustment of the application surface to the desired order quantity and / or to the width of the filter material strip easily and quickly is achieved. A dry filter removal can, for example, be made by completely closing or sealing off the application surface. In this case, the order area has the size zero. Dry filters are filters without additives. At the same time a promotion of the additive can take place, wherein the additive is not applied by the partitioning on the filter material.

Der Zusatzstoff wird gleichmäßig auf das Filtermaterial aufgetragen, wenn die auf das Filtermaterial zugeführte Zusatzstoffmenge pro Zeiteinheit und/oder pro Auftragsfläche konstant gehalten wird.The additive is uniformly applied to the filter material when the amount of additive applied to the filter material per unit of time and / or per application surface is kept constant.

In weiterer Ausgestaltung der Erfindung wird der vom Filtermaterial nicht aufgenommene Zusatzstoff abgeleitet und/oder gesammelt.In a further embodiment of the invention, the additive not absorbed by the filter material is derived and / or collected.

Die Haftung zwischen Filtermaterial und Zusatzstoff wird verstärkt, wenn das Filtermaterial und/oder der Zusatzstoff mit Ladung beaufschlagt werden.Adhesion between filter material and additive is enhanced when charge is applied to the filter material and / or the additive.

Ein gleichmäßiger Auftrag des Zusatzstoffs auf das Filtermaterial wird dadurch erreicht, daß der Zusatzstoff von wenigstens einer Düse auf wenigstens eine Seite der Bahn aus Filtermaterial aufgesprüht wird. Bevorzugt sind mehrere Düsen auf einer Seite vorgesehen. Insbesondere können die Düsen in mehreren Reihen angeordnet werden.A uniform application of the additive to the filter material is achieved by spraying the additive from at least one nozzle onto at least one side of the web of filter material. Preferably, a plurality of nozzles are provided on one side. In particular, the nozzles can be arranged in several rows.

Eine Vergleichmäßigung des Auftrags auf das Filtermaterial wird ausgeführt, wenn die wenigstens eine Düse mit einem konstanten Druck beaufschlagt wird. Durch einen gleichbleibenden Systemdruck wird eine optimale Tröpfchengröße und/oder -geschwindigkeit des Zusatzstoffes erreicht. Bei der Verwendung mehrerer Sprühdüsen können sich die Sprühgebilde in Form von Sprühkegeln oder Sprührechtecken überdecken.A homogenization of the order on the filter material is carried out when the at least one nozzle is subjected to a constant pressure. Consistent system pressure achieves optimum droplet size and / or velocity of the additive. When using multiple spray nozzles, the sprays may overlap in the form of spray cones or spray patches.

Vorteilhafterweise wird als Zusatzstoff Triacetin auf das Filtermaterial aufgebracht. Triacetin hat sich bei der Herstellung von Filterstäben als geeigneter Weichmacher und Vernetzer bewährt.Advantageously, triacetin is applied to the filter material as an additive. Triacetin has proven to be a useful plasticizer and crosslinker in the production of filter rods.

Gelöst wird die Aufgabe ferner durch eine Einrichtung der eingangs genannten Art, die dadurch weitergebildet ist, daß die Größe der Auftragsfläche mittels eines verfahrbaren Abdeckelements einstellbar ist.The object is further achieved by a device of the type mentioned, which is further developed in that the size of the application surface is adjustable by means of a movable cover.

Vorteilhafterweise ist die Auftragsfläche, insbesondere mittels wenigstens eines Abdeckelements, veränderbar.Advantageously, the application surface, in particular by means of at least one cover, changeable.

In einer weiteren Ausgestaltung der Erfindung sind wenigstens ein Mittel zum Ableiten und/oder wenigstens ein Sammelmittel für den vom Filtermaterial nicht aufgenommenen Zusatzstoff vorgesehen.In a further embodiment of the invention, at least one means for discharging and / or at least one collection means are provided for the additive not received by the filter material.

Außerdem ist erfindungsgemäß vorgesehen, daß wenigstens eine Spannungsquelle zur Beaufschlagung des Filtermaterials und/oder des Zusatzstoffes mit Ladung vorgesehen ist.In addition, the invention provides that at least one voltage source is provided for charging the filter material and / or the additive with charge.

Zur Aufbringung des Zusatzstoffes auf das Filtermaterial ist ferner wenigstens eine Düse auf wenigstens einer Seite der Bahn aus Filtermaterial vorgesehen. Vorzugsweise sind mehrere Düsen auf einer Seite, insbesondere in mehreren Reihen, angeordnet.For application of the additive to the filter material at least one nozzle is further provided on at least one side of the web of filter material. Preferably, a plurality of nozzles are arranged on one side, in particular in a plurality of rows.

Ein gleichmäßiger Auftrag des Zusatzstoffes auf das Filtermaterial ist insbesondere dann möglich, wenn die wenigstens eine Düse mit einem konstanten Druck beaufschlagbar ist.A uniform application of the additive to the filter material is particularly possible if the at least one nozzle can be acted upon by a constant pressure.

Um möglichst wenig Zusatzstoff, z.B. Weichmacher aus der Einrichtung austreten zu lassen, ist wenigstens eine Austrittsbarriere vorgesehen.To minimize the amount of additive, e.g. To let plasticizers escape from the device, at least one exit barrier is provided.

Überschüssiger, nicht aufgenommener Zusatzstoff kann in der Einrichtung zurückgeführt werden, wenn das Mittel zum Ableiten als Bandelement ausgebildet ist.Excess unabsorbed additive may be recycled to the device if the deriving means is formed as a band member.

Bevorzugterweise ist das Sammelmittel für nicht aufgenommenen Zusatzstoff als Abstreifkante und/oder als Becken ausgebildet.Preferably, the collecting means for unadapted additive is designed as a scraping edge and / or as a basin.

Schließlich ist gemäß der Erfindung ein Gehäuse für die Einrichtung vorgesehen.Finally, according to the invention, a housing is provided for the device.

Die Vorrichtung löst ebenfalls die Aufgabe der Erfindung durch eine voranstehend beschriebene Einrichtung.The device also achieves the object of the invention by a device described above.

Durch die Erfindung wird erreicht, daß der Weichmacher, z.B. Triacetin, gleichmäßig auf das Filtertow aufgesprüht wird. Hierbei wird die aufzutragende Menge an Zusatzstoff über eine verstellbare Auftragsfläche eingestellt, wobei der vom Filtermaterial nicht aufgenommene Überschuß abgeleitet wird. Hierzu kann der nicht aufgenommene Weichmacher von einem umlaufenden Band aufgenommen werden und von einer Abstreifkante abgestreift werden. Der Auftrag des Weichmachers kann durch das Aufbringen entgegengesetzter Ladungen auf das Filtertow bzw. auf den Zusatzstoff unterstützt werden.By the invention it is achieved that the plasticizer, e.g. Triacetin, is sprayed evenly on the filter tow. In this case, the amount of additive to be applied is adjusted via an adjustable application surface, whereby the excess not absorbed by the filter material is dissipated. For this purpose, the unobstructed plasticizer can be absorbed by a circulating belt and stripped off by a scraping edge. The application of the plasticizer may be assisted by the application of opposite charges to the filter tow or to the additive.

Zwischen den Sprühdüsen 3 und dem Filtertow 2 ist ein verfahrbares, insbesondere motorangetriebenes, Abdeckblech 7 angeordnet, so daß die Sprühfläche der Sprühkegel 4 begrenzt wird und der Auftrag des Weichmachers über eine Auftragsfläche 12 erfolgt. Die Auftragsfläche 12 ist variabel in ihrer Größe und hat bspw. bei einer Trockenfilterentnahme eine Fläche von Null. Hierbei ist der Sprühnebel 4 vollständig von einem Auftrag auf das Filtertow 2 abgeschottet. Die Größe der Auftragsfläche 12 ist je nach Anwendungsfall und Filtertowsorte bzw. Filtertowmenge vergrößerbar oder verkleinerbar, wobei die Sprühdüsen 3 nach wie vor mit einem konstanten Förderdruck beaufschlagt sind. Dies erzeugt ein insgesamt konstantes Sprühbild.The spray nozzles 3 are supplied with a constant system pressure from one or more delivery sources to ensure optimum droplet size and velocity. For the resulting spray pattern, the spray cone 4 can cover. The spray nozzles 3 are arranged below the filter tow 2 and spray the filter towed over 2 from below. Between the spray nozzles 3 and the filter tow 2, a movable, in particular motor-driven, cover plate 7 is arranged so that the spray surface of the spray cone 4 is limited and the application of the plasticizer takes place via an application surface 12. The application surface 12 is variable in size and has, for example. In a dry filter removal an area of zero. Here, the spray 4 is completely sealed off from an order on the filter tow 2. The size of the application surface 12 can be increased or reduced depending on the application and filter tow type or amount of filter tow, the spray nozzles 3 are still acted upon by a constant discharge pressure. This produces an overall constant spray pattern.

Um ein besseres Anhaften der Weichmacherpartikel der Sprühnebel 4 auf dem Filtertow 2 zu erreichen, ist ferner eine Spannungsquelle 10, insbesondere Hochspannungsquelle, vorgesehen, so daß die Sprühpartikel mit einer Ladung versehen werden. Die Beaufschlagung des Filtertows 2 mit elektrischen Ladungen ist bspw. in der Offenlegungsschrift DE-A-42 09 606 offenbart.In order to achieve a better adhesion of the plasticizer particles of the spray mist 4 on the filter tow 2, a voltage source 10, in particular a high voltage source, is further provided, so that the spray particles are provided with a charge. The loading of the filter tow 2 with electrical charges is, for example, in the published patent application DE-A-42 09 606 disclosed.

Die Regulierung der Auftragsmenge des Weichmachers auf das Filtertow 2 erfolgt durch das verfahrbare Abdeckblech 7, die je nach Anforderung mehr oder weniger Sprühfläche der Sprühkegel 4 überdeckt. Das Abdeckblech 7 ist bspw. als biegsames Federblech ausgebildet und wird per Motor und/oder Spindel in Towrichtung bewegt.The regulation of the order quantity of the plasticizer on the filter tow 2 is effected by the movable cover plate 7, which covers more or less spray area of the spray cone 4 as required. The cover plate 7 is formed, for example, as a flexible spring plate and is moved by motor and / or spindle in the direction of tow.

Oberhalb des Filtertows 2 ist ein umlaufendes Band 5 über die gesamte Länge der Einrichtung 1 ausgebildet, das über die Rollen 9 umläuft. Das Band 5 nimmt an seiner dem Filtertow 2 zugewandten Oberfläche den vom Filtertow 2 nicht aufgenommenen Weichmacher auf. Das Band 5 wird nach einer Umlenkung unter einer Abstreifkante 6 entlanggeführt, um das überflüssige Triacetin auf dem Band 5 abzuführen. Die Geschwindigkeit des Bandes 5 liegt dabei vorzugsweise unterhalb der Grenze, bei der sich ein Tropfen des Weichmachers bei der Umlenkung lösen würde. Die Bandgeschwindigkeit liegt somit vorzugsweise erheblich unterhalb der Filtertowgeschwindigkeit. Am Auslauf der Einrichtung 1 sind parallel zueinander angeordnete Sprühnebelbarrieren 8 ausgebildet, die bewirken, daß möglichst wenig Weichmacher aus der Einrichtung 1 austritt. Vorzugsweise ist die Einrichtung 1 mit einem Gehäuse versehen.Above the filter tow 2 a circumferential band 5 is formed over the entire length of the device 1, which rotates about the rollers 9. The band 5 receives on its the filter tow 2 facing surface on the not absorbed by the filter tow 2 plasticizer. The band 5 is guided along a deflecting under a scraper edge 6 to dissipate the excess triacetin on the belt 5. The speed of the belt 5 is preferably below the limit at which a drop of the plasticizer would dissolve during the deflection. The belt speed is thus preferably considerably below the filter speed. At the outlet of the device 1 are arranged parallel to each other spray barrier 8, which cause as little as possible plasticizer from the device 1 exits. Preferably, the device 1 is provided with a housing.

Die von dem Band 5 aufgenommene Weichmachermenge wird über die quer zum Band 5 angeordnete Abstreifkante 6 abgestreift. Dabei gelangt die Weichmacherflüssigkeit wieder in den unteren Bereich der Einrichtung 1. Hierbei wird die Flüssigkeit am unteren Rand gesammelt in einer Art Becken oder Wanne, die auch mit einer Neigung versehen sein kann. Über einen Rücklauf 11 wird die überschüssige Auftragsmenge abgeführt und in den Vorratsbehälter, aus dem die Sprühdüsen gespeist werden, zurückgeleitet.The quantity of plasticizer received by the band 5 is scraped off via the scraping edge 6 arranged transversely to the band 5. In this case, the plasticizer liquid passes back into the lower region of the device 1. Here, the liquid is collected at the bottom in a kind of basin or tub, which may also be provided with a slope. Via a return 11, the excess application amount is removed and returned to the reservoir from which the spray nozzles are fed.

In den Figuren 2a und 2b sind schematische, perspektivische Ansichten der Einrichtung 1 dargestellt, wobei zum besseren Verständnis und Veranschaulichung entsprechende Teile weggelassen wurden. Die Sprühdüsen 3 sind in regelmäßigen Abständen unterhalb des Filtertows 2 angeordnet und erzeugen eine zweidimensionale Sprühfläche bzw. Auftragsfläche 12. Durch den konstanten Förderdruck des Weichmachers wird mittels der Sprühdüsen 3 eine gleichmäßige Aufbringung des Weichmachers auf das Filtertow 2 erreicht. Die Abstreifkante 6 auf der Oberseite des Bandes 5 ist quer zur Laufrichtung des Bandes 5 angeordnet, so daß die vom Band 5 aufgenommene Flüssigkeit zu mindestens einer Seite des Bandes geleitet wird und an diesem herunterläuft und in einem Auffangbecken oder -wanne aufgefangen wird. Wie in Fig. 2b angedeutet, ist das Abdeckblech 7 verfahrbar, so daß die Auftragsfläche 12 vergrößert oder verkleinert werden kann.FIGS. 2 a and 2 b show schematic, perspective views of the device 1, with corresponding parts being omitted for better understanding and illustration. The spray nozzles 3 are arranged at regular intervals below the filter tow 2 and produce a two-dimensional spray surface or application surface 12. Due to the constant delivery pressure of the plasticizer, a uniform application of the plasticizer to the filter tow 2 is achieved by means of the spray nozzles 3. The scraper edge 6 on the upper side of the belt 5 is arranged transversely to the running direction of the belt 5, so that the liquid picked up by the belt 5 is directed to at least one side of the belt and runs down the belt and is collected in a catch basin or trough. As indicated in Fig. 2b, the cover plate 7 is movable, so that the application surface 12 can be increased or decreased.

Wie in Fig. 3a und 3b gezeigt, kann der Auftrag des Weichmachers auch von oben auf das Filtertow 2 erfolgen. Die vom Filtertow 2 nicht aufgenommene Weichmachermenge wird von dem Abdeckblech zu den Seiten abgeführt, und in die untere Auffangwanne 13 abgeleitet. Über den Rücklauf 11 wird die überschüssige Weichmachermenge dem Fördertank wieder zugeführt.As shown in FIGS. 3 a and 3 b, the application of the plasticizer can also be carried out from above onto the filter tow 2. The not absorbed by the filter tow 2 amount of plasticizer is discharged from the cover plate to the sides, and discharged into the lower sump 13. About the return 11, the excess amount of plasticizer is fed back to the feed tank.

Bei dem in den Figuren 4a und 4b gezeigten Anwendungsbeispiel erfolgt die Aufbringung des Weichmachers von der Seite, wobei das Filtertow 2 vertikal ausgebreitet ist.In the application example shown in FIGS. 4a and 4b, the application of the plasticizer takes place from the side, the filter tow 2 being spread vertically.
