Abstract
Description
Die Erfindung betrifft ein Verfahren zum Herstellen von mit Zellulose-Acetatfiltern bestückten stabförmigen Rauchartikeln der tabakverarbeitenden Industrie durch Trennung von jeweils in mehrfacher, insbesondere doppelter Stablänge zusammengefügten Tabak- und Filterkomponenten in der Mitte eines Filterstabes.The invention relates to a method for producing rod-shaped smoking articles in the tobacco processing industry which are equipped with cellulose acetate filters by separating tobacco and filter components which are combined in multiple, in particular double rod lengths, in the middle of a filter rod.
Die Erfindung betrifft außerdem eine Vorrichtung zum Herstellen von mit Zellulose-Acetatfiltern bestückten stabförmigen Artikeln der tabakverarbeitenden Industrie durch Trennung von jeweils in mehrfacher, insbesondere doppelter Stablänge zusammengefügten Tabak- und Filterkomponenten in der Mitte eines Filterstabes.The invention also relates to a device for producing rod-shaped articles in the tobacco processing industry equipped with cellulose acetate filters by separating tobacco and filter components in the middle of a filter rod, each of which is combined in multiple, in particular double rod lengths.
Im Zuge der Herstellung von Filterzigaretten, deren Filter sich üblicherweise aus mehr oder weniger intensiv miteinander vernetzten Zellulose-Acetatfasern oder ähnlichem bzw. anderem vergleichbaren Filtermaterial zusammensetzen, können sich beim Trennvorgang einzelne willkürlich durchtrennte Fasern, insbesondere kleinere bzw. kürzere Fasern aus dem Fasernverbund, insbesondere von der unmittelbaren Trennfläche des Filterstabes lösen, was einen ästhetisch nachteiligen Eindruck hervorruft.
Die ohnehin in der Raumluft der Fabrikationsstätte vorhandenen und gegebenenfalls ausgefilterten und in den Herstellungsprozeß zurückgeführten Tabakfeinpartikel werden auf diese Weise durch Fremdpartikel aus Acetatfasern belastet bzw. verunreinigt. Auch können sich derartige Filterfasern bei der weiteren Handhabung, z.B. bei Förderung zur Packmaschine und bei der Verpackung selbst noch lösen.In the course of the production of filter cigarettes, the filters of which are usually composed of more or less intensely cross-linked cellulose acetate fibers or similar or other comparable filter material, individual, arbitrarily cut fibers, in particular smaller or shorter fibers from the fiber composite, in particular, can occur during the separation process detach from the immediate separating surface of the filter rod, which creates an aesthetically disadvantageous impression.
In this way, the fine tobacco particles that are present in the ambient air of the manufacturing facility and are filtered out and returned to the manufacturing process are contaminated or contaminated by foreign particles made of acetate fibers. Such filter fibers can also become detached during further handling, for example when conveying to the packaging machine and during packaging.
Der Erfindung liegt die Aufgabe zugrunde, den genannten Qualitätskriterien hinsichtlich der Fabrikationsbedingungen und der Produktqualität besser gerecht zu werden.The invention has for its object to better meet the quality criteria mentioned in terms of manufacturing conditions and product quality.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß eine unkontrollierte Ablösung freier bzw. lose haftender Acetatfasern von den Trennflächen des Filterstabes verhindert wird.This object is achieved in that an uncontrolled detachment of free or loosely adhering acetate fibers from the separating surfaces of the filter rod is prevented.
Eine bevorzugte Verfahrensweise besteht nach einem weiteren Vorschlag darin, daß die Acetatfasern nach der Durchtrennung des Filterstabes von den Trennflächen entfernt werden.
Auf besonders effektive Weise können die Acetatfasern unter Anlegen eines Unterdruckes an die Trennflächen durch pneumatische Absaugung entfernt werden.
Eine alternative Entfernung der Acetatfasern kann nach einem weiteren Vorschlag durch von außen auf die Trennflächen einwirkende elektrostatische Anziehung bzw. Absaugung erfolgen.According to a further proposal, a preferred procedure is that the acetate fibers are removed from the separating surfaces after the filter rod has been severed.
The acetate fibers can be removed in a particularly effective manner by applying a vacuum to the separating surfaces by means of pneumatic suction.
According to a further proposal, an alternative removal of the acetate fibers can be carried out by electrostatic attraction or suction acting on the separating surfaces from the outside.
Eine unkontrollierte Ablösung lose haftender Fasern kann im Sinne der Erfindung durch Einbindung der Acetatfasern nach einem weiteren Vorschlag dadurch erfolgen, daß die Acetatfasern nach Durchtrennung des Filterstabes an den Trennflächen fixiert werden.
Vorschlagsgemäß kann eine derartige Fixierung der Acetatfasern durch Aufbringen eines Lösungsmittels auf die Trennflächen oder aber durch Einwirkung einer Wärmequelle auf die Trennflächen erfolgen. Als Wärmequellen sind hierbei unterschiedliche Einwirkungen denkbar, beispielsweise in Form einer Warmlufteinheit oder in Form einer intensiven Wärmestrahlung in Form einer IR-Strahlung. Auf diese Weise werden die zuvor losen Fasern regelrecht mit der Trennfläche verschmolzen, wobei selbstverständlich für die Einhaltung eines bestimmten Zugwiderstandes Sorge zu tragen ist.
Für eine ursprüngliche Einbindung der Acetatfasern in die Filteroberfläche liegt es vorschlagsgemäß im Rahmen der Erfindung, wenn die Wärmeeinwirkung unmittelbar in den Trennvorgang integriert ist, was nach einem weiteren Vorschlag dadurch erreicht wird, daß der Trennvorgang durch Brennschneiden erfolgt, wozu sich zum Beispiel ein Laserschnitt eignet. Eine Fixierung der Acetatfasern an der Trennfläche kann außerdem dadurch erreicht werden, daß die Acetatfasern durch Aufsetzen eines Schutzfilters auf die Trennfläche zurückgehalten werden.An uncontrolled detachment of loosely adhering fibers can take place in accordance with the invention by incorporating the acetate fibers according to a further proposal in that the acetate fibers are fixed to the separating surfaces after the filter rod has been severed.
According to the proposal, the acetate fibers can be fixed in this way by applying a solvent to the separating surfaces or by the action of a heat source on the separating surfaces. Different influences are conceivable as heat sources, for example in the form of a warm air unit or in the form of intensive heat radiation in the form of IR radiation. In this way, the previously loose fibers are literally fused to the separating surface, whereby of course care must be taken to maintain a certain tensile resistance.
For an original integration of the acetate fibers in the According to the proposal, the filter surface is within the scope of the invention if the action of heat is integrated directly into the separation process, which according to a further proposal is achieved in that the separation process is carried out by flame cutting, for which purpose laser cutting is suitable. A fixation of the acetate fibers on the separation surface can also be achieved in that the acetate fibers are retained by placing a protective filter on the separation surface.
Die Vorrichtung zur Durchführung des eingangs bezeichneten Verfahrens besteht aus einer Einrichtung zum Verbessern der Trennflächen des Filterstabes.
Auf besonders effektive Weise ist eine derartige Einrichtung in der Weise einsetzbar, indem die Trennflächen des auf einem rotativen Fördermittel transportierten Filterstabes an einer Fasern-Abnahmeeinrichtung vorbeibewegbar sind, welche gemäß einer vorgeschlagenen bevorzugten Ausgestaltung einen in eine die Trennfläche gegen die Atmosphäre abdichtende Kammer einmündenden Saugluftanschluß aufweist.
Nach einem weiteren alternativen Vorschlag kann die Abnahmeeinrichtung mit der Trennfläche zugewandten Elektroden zur Erzeugung eines elektrischen Feldes ausgestattet sein, welches durch entgegengesetzte elektrostatische Aufladung lose Fasern von der Trennfläche anzieht und gegebenenfalls mit Unterstützung von Saugluft abführt.
Ein alternativer Vorschlag zum Unschädlichmachen der losen Kurzfasern kann durch deren Einbindung in die Trennfläche erfolgen, indem die Trennflächen des auf einem rotativen Fördermittel transportierten Filterstabes an einer Faser-Fixierstation vorbeibewegbar sind.
Eine derartige Fixierstation kann gemäß Alternativvorschlägen eine gegen die Trennfläche gerichtete Lösemittel-Sprüheinrichtung aufweisen, oder aber mit einer Wärmequelle ausgestattet sein, so daß in beiden Fällen durch Anlösen bzw. Anschmelzen der losen Fasern deren Verklebung an der Trennfläche erfolgt.The device for carrying out the method described in the introduction consists of a device for improving the separating surfaces of the filter rod.
Such a device can be used in a particularly effective manner in that the separating surfaces of the filter rod transported on a rotating conveying means can be moved past a fiber removal device which, according to a proposed preferred embodiment, has a suction air connection opening into a chamber sealing the separating surface against the atmosphere .
According to a further alternative proposal, the removal device can be equipped with electrodes facing the separating surface for generating an electric field which attracts loose fibers from the separating surface by opposing electrostatic charging and, if necessary, removes them with the aid of suction air.
An alternative proposal for rendering the loose short fibers harmless can be made by integrating them into the separating surface, in that the separating surfaces of the filter rod transported on a rotating conveying means can be moved past a fiber fixing station.
According to alternative proposals, such a fixing station can have a solvent spray device directed against the separating surface, or can be equipped with a heat source be so that in both cases, by loosening or melting the loose fibers, they are glued to the separating surface.
Die Wärmequelle kann nach einem weiteren Vorschlag auch durch eine Trennvorrichtung selbst gebildet werden, welche beispielsweise als Laserstrahl-Schneidmittel ausgebildet ist, welches die mit dem Schnitt durchtrennten und dabei gleichzeitig angeschmolzenen Fasern unmittelbar mit der Trennfläche verklebt.
Eine Fixierung bzw. ein Zurückhalten loser Fasern an der Trennfläche ist im Sinne der Erfindung außerdem mit Hilfe eines die Trennfläche abdeckenden Schutzfilters möglich.According to a further proposal, the heat source can also be formed by a separating device itself, which is designed, for example, as a laser beam cutting means, which glues the fibers cut through and simultaneously melted onto the separating surface.
A fixation or retention of loose fibers on the separating surface is also possible in the sense of the invention with the aid of a protective filter covering the separating surface.
Der mit der Erfindung erzielte Vorteil besteht darin, daß praktisch mit dem Zeitpunkt des Entstehens bzw. unmittelbar an der Entstehungsstelle die losen Faserbestandteile des Filters von der Trennfläche entfernt oder an dieser fixiert werden, sodaß diese Fläche einen ästhetisch ansprechenden Anblick bietet und lose Faserbestandteile keine störenden Einflüsse bei der weiteren Handhabung, z. B. bei der Förderung der Filterzigaretten zu den Packmaschinen und bei der Verpackung selbst, ausüben können.The advantage achieved by the invention is that practically at the point of origin or immediately at the point of origin, the loose fiber components of the filter are removed from or fixed to the separating surface, so that this surface offers an aesthetically pleasing sight and loose fiber components are not a problem Influences in further handling, e.g. B. in the promotion of filter cigarettes to the packaging machines and in the packaging itself.

Die in den Figuren 1 und 2 dargestellte Einrichtung 1 zum Verhindern einer unkontrollierten Fasernablösung von der Trennfläche 2 eines an das Mundstückende einer Zigarette 3 angesetzten Filterstabes 4 ist als Fasern-Abnahmeeinrichtung 6 ausgebildet, die mit einem Sauganschluß 7 ausgestattet ist. Der Sauganschluß 7 ist Teil eines stationären Schleifschuhes 8, welcher dicht mit der Stirnseite 9 einer rotierenden Fördertrommel 11 kontaktiert. Die Fördertrommel 11 weist am Umfang Aufnahmemulden 12 auf, in denen die Zigaretten 3 liegen und mit den Enden ihrer Filterstäbe 4 in gegen die Atmosphäre abgedichtete Kammern 13 hineinragen, welche über Saugbohrungen 14, 16 der Fördertrommel 11 bzw. des Schleifschuhes 8 beim Trommelumlauf nacheinander kurzzeitig mit dem Saugluftanschluß 7 kommunizieren. Während dieser kurzzeitigen Verbindung zwischen der jeweiligen Saugbohrung 14 der Fördertrommel 11 und der ortsfesten Saugbohrung 16 des Schleifschuhes 8 werden lose an der Trennfläche 2 haftende Fasern über den Saugluftanschluß 7 abgesaugt.The
Bei den in den Figuren 3 bis 7 dargestellten Varianten der Einrichtung 1 sind Teile die denen der Figuren 1 und 2 entsprechen mit um einhundert bzw. zweihundert bzw. dreihundert bzw. vierhundert bzw. fünfhundert erhöhten Bezugszahlen versehen und nicht noch einmal besonders erläutert.In the variants of the
Bei der in Figur 3 dargstellten Einrichtung 101 werden die Zigaretten 103 ebenfalls mittels einer nicht dargestellten Fördertrommel mit den Enden ihrer Filterstäbe 104 mit einem Abstand zwischen deren Trennfläche 102 und der Abnahmeeinrichtung 106 rotativ an dieser vorbeibewegt. Die Abnahmeeinrichtung 106 weist in diesem Fall eine Elektrode 117 zur Erzeugung eines elektrischen Feldes mit entgegengesetzter elektrostatischer Aufladung relativ zum Filterstab 104 auf. Auf diese Weise werden die lose haftenden Fasern von der Trennfläche 102 angezogen und danach mit Unterstützung von Saugluft über Radialbohrungen 118 der Abnahmeeinrichtung 106 mittels einer Saugluftquelle 119 abgezogen, wobei die Fasern in einem Filter 121 abgesondert und entsorgt werden.In the device 101 shown in FIG. 3, the cigarettes 103 are likewise rotated past the ends of their filter rods 104 by means of a conveyor drum, not shown, with a distance between their separating surface 102 and the removal device 106. In this case, the removal device 106 has an electrode 117 for generating an electric field with opposite electrostatic charging relative to the filter rod 104. In this way, the loose adherent fibers from the Partition surface 102 attracted and then drawn off with the aid of suction air via radial bores 118 of the take-off device 106 by means of a suction air source 119, the fibers being separated and disposed of in a filter 121.
Gemäß den Figuren 4 und 5 ist die Einrichtung 201 als Faser-Fixierstation 222 ausgebildet, an der die Fördertrommel 211 mit der Umfangsfläche eines stirnseitigen Steuerringes 223 schleifend entlangbewegbar ist, wobei nacheinander einer jeden Kammer 213 zugeordnete, den Steuerring 223 durchsetzende Bohrungen 224 mit Düsenöffnungen 226 ortsfeste Bohrungen 227, 228, 229 der Fixierstation 222 passieren. Durch die erste Bohrung 227 tritt dabei aus einem Lösungsmittel- bzw. Triacetinvorrat 231 der Fixierstation 222 tropfenweise Triacetin in die Bohrungen 224 der Düsenöffnung 226 ein. Beim fluchtenden Passieren der Bohrungen 228 und 229 tritt aus einer mit diesen verbundenen Druckluftkammer 232 Druckluft in die Bohrungen 224 ein und versprüht dabei Triacetintropfen aus der Düsenöffnung 226 gegen die Trennfläche 202 des Filterstabes 204, wodurch die Acetatfasern angelöst und an der Trennfläche 202 verklebt werden.According to FIGS. 4 and 5, the
Die in Figur 6 dargestellte Fixierstation 322 weist statt einer Sprüheinrichtung zum Anlösen der Fasern eine Wärmequelle 333 zum Anschmelzen der Fasern auf, welche auf diese Weise ebenfalls an der Trennfläche 302 fixiert werden.Instead of a spray device for detaching the fibers, the fixing
Die Anordnung gemäß Figur 7 unterscheidet sich von der vorhergehenden Anordnung dadurch, daß die Wärmequelle 433 durch eine Trennvorrichtung in Form eines Laserstrahl-Schneidmittels 434 gebildet wird, dessen den Trennschnitt erzeugende Wäremeinwirkung zugleich die Filterfasern anschmilzt und mit der Trennfläche verklebt.The arrangement according to FIG. 7 differs from the previous arrangement in that the
Bei der in Figur 8 gezeigten Variante werden die Acetatfasern durch einen Schutzfilter 536, beispielsweise in Form eines Papierfilters mit entsprechender Porosität, an der Trennfläche 502 fixiert bzw. zurückgehalten. Der Schutzfilter 536 kann entweder wie dargestellt in Scheibenform an das Ende des Filterstabes 504 angesetzt oder aber in nicht dargestellter Weise in Form einer festen Hülse über den Filterstab geschoben werden.In the variant shown in FIG. 8, the acetate fibers are fixed or retained on the separating
