Aufgabe der vorliegenden Erfindung ist es, die vorgenannten Vorrichtungen weiter zu verbessern.The object of the present invention is to further extend the aforementioned devices to improve.
Diese Aufgabe wird bei einer Vorrichtung der eingangs genannten Art dadurch gelöst, daß die mitlaufende Seitenwand Ausnehmungen für eine abschnittsweise Verstärkung des Faserstranges aufweist.This object is achieved in a device of the type mentioned solved that the idling side wall recesses for a section Has reinforcement of the fiber strand.
Der Vorteil einer derartigen Ausgestaltung der Seitenwand liegt insbesondere darin, daß auf diese Weise bereits während der Strangbildung eine abschnittsweise Verstärkung des Faserstranges vorgenommen werden kann. Zwar ist eine derartige abschnittsweise Verstärkung, bei der Herstellung von Zigaretten auch als Kopfverstärkung bezeichnet, im Stand der Technik beispielsweise aus DE 11 09 071 bekannt; bei diesen bekannten Vorrichtungen zur Kopfverstärkung werden zwei in einer Ebene mit dem Tabakstrang angeordnete Klemmscheiben verwendet, die als Trimmscheiben zur Überschußabnahme von dem Tabakstrang dienen und an ihren Umfängen Taschen aufweisen, in denen ein gewisser Überschuß auf dem Tabakstrang stehenbleibt, so daß dieser später beim Verdichten des Stranges zu einer stärker verdichteten Stelle führt. Diese Trimmscheiben üben jedoch zusätzliche Kräfte auf den Tabakstrang aus, die zu einer Gewichtsstreuung der auf diese Weise hergestellten Zigaretten führen. Die Erfindung vermeidet daher diesen Nachteil durch Vorverlagerung der Einbringung der Kopfverstärkung schon beim Aufschauern des Tabakstranges. The advantage of such a configuration of the side wall is in particular that that in this way a section by section already during strand formation Reinforcement of the fiber strand can be made. Such is one Sectional reinforcement, also in the manufacture of cigarettes Designated head reinforcement, in the prior art for example from DE 11 09 Known 071; in these known devices for head reinforcement two Clamping disks arranged in a plane with the tobacco rod are used serve as trim discs for excess takeoff from the tobacco rod and on their circumference have pockets in which a certain excess on the The tobacco rod remains so that it later closes when the rod is compacted leads to a more compacted area. However, these trim discs practice additional ones Forces exerted on the tobacco rod, resulting in weight spreading this way lead manufactured cigarettes. The invention therefore avoids this disadvantage by advancing the insertion of the head reinforcement already when looking up of the tobacco rod.
Weiterhin ist es bei der Erfindung vorteilhaft, daß die Qualität der Kopfverstärkung verbessert wird. Denn aufgrund der mitlaufenden Seitenwände wird die Kopfverstärkung in den Tabakstrang ohne Relativbewegung zwischen Kopfverstärkungsmittel und Tabakstrang eingeführt. Die Kopfverstärkung läßt sich daher wesentlich regelmäßiger und präziser einbringen.Furthermore, it is advantageous in the invention that the quality of the head reinforcement is improved. Because of the moving side walls, the head reinforcement into the tobacco rod without relative movement between head reinforcement and introduced tobacco rod. The head reinforcement can therefore be essential Apply more regularly and precisely.
Bei einer bevorzugten Ausführungsform der Erfindung ist die mitlaufende Seitenwand als mindestens ein umlaufender Riemen, bevorzugt als Zahnriemen ausgebildet. Mit Hilfe eines solchen Zahnriemens läßt sich die Erfindung einfach verwirklichen. Denn ein Zahnriemen läßt sich mit Hilfe von Zahnscheiben antreiben. Dabei ist bevorzugt, wenn die den Zahnriemen antreibende Zahnscheibe als ein Ring aus die Zähne der Zahnscheiben bildenden Stäben aufgebaut ist. Eine solche hamsterkäfigartige Ausbildung der antreibenden Zahnscheibe verhindert zum einen eine Verschmutzung der Zahnlücken der Zahnscheibe und zum anderen eine Verschmutzung des Riemens bzw. der entsprechenden Zähne des Riemens. Die Verschmutzung kann weiter auf ein Minimum reduziert werden, wenn die Stäbe der Zahnscheibe bzw. der Zahnriemen selbst mit einer speziellen schmutzabweisenden Beschichtung beschichtet werden. Darüber hinaus ist es bei einem Riemen vorteilhaft, daß er durch Vergrößerung des Abstandes der ihn umlenkenden Zahnscheiben einfach gespannt werden kann.In a preferred embodiment of the invention, the co-rotating Side wall as at least one circumferential belt, preferably as a toothed belt educated. With the help of such a toothed belt, the invention is simple realize. Because a toothed belt can be driven with the help of toothed pulleys. It is preferred if the toothed pulley driving the toothed belt as a ring is constructed from rods forming the teeth of the toothed lock washers. Such Hamster cage-like design of the driving toothed disc prevents on the one hand contamination of the tooth gaps of the toothed disk and, on the other hand, one Contamination of the belt or the corresponding teeth of the belt. The Contamination can be further reduced to a minimum if the bars of the Toothed pulley or the toothed belt itself with a special dirt-repellent Coating can be coated. It is also a strap advantageous that he by increasing the distance of the deflecting him Toothed lock washers can be easily clamped.
Eine weiter reduzierte Verschmutzung des erfindungsgemäßen Riemens läßt sich dadurch erreichen, daß ein Flachriemen, d.h. ein Riemen ohne Zähne verwendet wird. Wenn ein Flachriemen verwendet wird, so wird wegen des Schlupfes zwischen Antriebsscheibe und Riemen die Lage der Ausnehmungen relativ zum späteren Schnitt, also zum durch den Messerapparat zum Schneiden des Zigarettenstranges bestimmten Maschinentakt, abgefragt und fortlaufend synchronisiert.A further reduced contamination of the belt according to the invention can be in that a flat belt, i.e. a strap without teeth is used becomes. If a flat belt is used, it will because of the slippage the position of the recesses relative to the drive pulley and belt later cut, i.e. for cutting through the knife apparatus Cigarette rod specific machine cycle, queried and continuously synchronized.
Bei einer weiteren bevorzugten Ausführungsform der vorliegenden Erfindung weist die nicht antreibende Umlenkscheibe für den Zahnriemen keine Zähne auf. Auch mit Hilfe einer solchen Maßnahme läßt sich die mögliche Verschmutzung der entsprechenden Zahnscheibe und des umlaufenden Zahnriemens weiter minimieren.In a further preferred embodiment of the present invention the non-driving pulley for the toothed belt has no teeth. Also with With the help of such a measure, the possible pollution of the further minimize the corresponding toothed pulley and the rotating toothed belt.
Bei einer anderen vorteilhaften Ausführungsform der Erfindung ist der Zahnriemen bis an den Formateinlauf der entsprechenden Zigarettenherstellungsmaschine weitergeführt. Auf diese Weise läßt sich somit der Tabakstrang maximal lange mit mitlaufenden Seitenwänden begleiten.In another advantageous embodiment of the invention, the toothed belt to the format infeed of the corresponding cigarette making machine continued. In this way, the tobacco rod can be used for a long time accompany moving side walls.
Besonders bevorzugt ist es, wenn die antreibende Zahnscheibe von einem digitalen Servoantriebssystem angetrieben wird. Mit Hilfe eines derartigen Antriebssystems läßt sich die Drehzahl des antreibenden Motors derart genau regeln, daß eine exakte Positionierung der Kopfverstärkung zum später folgenden Schnitt des Zigarettenstranges in die einzelnen Zigaretten gewährleistet ist. Das bedeutet, daß die Kopfverstärkungen sich jeweils exakt an den Enden der Tabakstöcke befinden.It is particularly preferred if the driving toothed pulley is from a digital one Servo drive system is driven. With the help of such a drive system the speed of the driving motor can be controlled so precisely that an exact Position the head reinforcement for the subsequent cut of the cigarette rod is guaranteed in the individual cigarettes. That means that Head reinforcements are located exactly at the ends of the tobacco sticks.
Bei weiteren bevorzugten Ausführungsbeispielen laufen nur eine oder beide Seitenwände mit dem Faserstrang mit oder weisen nur eine oder beide Seitenwände die Ausnehmungen zum Einbringen der Kopfverstärkungen auf. Mit Hilfe dieser verschiedenen Ausführungsformen kann somit individuell auf die jeweiligen Anforderungen an den herzustellenden Tabakstrang Rücksicht genommen werden.In further preferred exemplary embodiments, only one or both side walls run with the fiber strand or have only one or both side walls Recesses for introducing the head reinforcements. With the help of this Different embodiments can thus be customized to the respective Requirements for the tobacco rod to be produced are taken into account.
Weiterhin vorteilhaft ist es, wenn die Oberfläche der mitlaufenden Seitenwand mit einer elektrisch leitfähigen Beschichtung beschichtet ist. Auf diese Weise wird erreicht, daß sich die Seitenwand antistatisch verhält, und somit keine gefährlichen Ladungsanhäufungen in der Strangherstellungsmaschine erzeugt werden. Bei den erfindungsgemäßen Zahnriemen beträgt der Oberflächenwiderstand mit Hilfe einer derartigen Beschichtung weniger als 3 x 108 Ω, bevorzugt weniger als 106 Ω. Ein derartig beschichteter Zahnriemen erfüllt somit auch die DIN 22104 "Antistatische Fördergurte". It is also advantageous if the surface of the moving side wall is coated with an electrically conductive coating. In this way it is achieved that the side wall behaves antistatically and thus no dangerous accumulations of charge are generated in the strand production machine. In the toothed belt according to the invention, the surface resistance with the aid of such a coating is less than 3 × 10 8 Ω, preferably less than 10 6 Ω. A toothed belt coated in this way also fulfills DIN 22104 "Antistatic Conveyor Belts".
Als bevorzugte Materialien zur Herstellung der erfindungsgemäßen Riemen haben sich Polypolefine, insbesondere Polyethylene und Polypropylene, oder Hytrel, insbesondere Polyesterelastomer, bewährt.As preferred materials for making the belts according to the invention polypolefins, in particular polyethylenes and polypropylenes, or Hytrel, especially polyester elastomer, proven.
Besonders bevorzugt ist, wenn die Gesamtlänge des erfindungsgemäßen, umlaufenden Riemens ein ganzzahliges Vielfaches der Tabakstocklänge der herzustellenden Tabakstöcke darstellt und darüber hinaus durch die Teilung des Zahnriemes teilbar ist. Auf diese Weise wird sichergestellt, daß die schließlich hergestellten Tabakstöcke jeweils die Kopfverstärkungen nur an einem oder an ihren beiden Enden aufweisen, das heißt, daß eine exakte Positionierung der Kopfverstärkungen an den gewünschten Stellen erreicht wird.It is particularly preferred if the total length of the circumferential belt is an integral multiple of the length of the tobacco stick represents tobacco sticks to be produced and moreover by the division of the Toothed belt is divisible. This will ensure that the eventual manufactured tobacco sticks each the head reinforcements only on one or on their have both ends, that is, an exact positioning of the head reinforcements is reached at the desired locations.
Eine weitere vorteilhafte Ausführungsform der Erfindung zeichnet sich dadurch aus, daß sich der Strangführungskanal in Förderrichtung kontinuierlich verengt. Auf diese Weise ist es möglich, bereits vor dem Durchlauf des Tabakstranges durch den Egalisator eine Querschnittsverengung des Tabakstranges zu erreichen. Im Stand der Technik sind die ortsfesten Seitenwangen des Tabakkanals in Förderrichtung leicht divergierend angeordnet. Infolgedessen kommt es am Einlauf in das Format unter dem so genannten Einlauffinger, welcher die Umhüllung des Tabakstranges mit einem Hüllmaterialstreifen einleitet, zu einer relativ heftigen Querschnittsverengung, die bezüglich der Laufsicherheit der Maschine problematisch ist. Dank der erfindungsgemäß mitlaufenden Wange wird die Laufsicherheit der Maschine erhöht, weil der Tabakstrang ständig von der Seite her geführt, mitgenommen und leicht komprimiert wird. Auch lassen sich dank der Erfindung die im Stand der Technik teilweise zu beobachtenden Verschiebungen in der Strangstruktur verringern. Somit kann - wie zuvor erwähnt - bereits vor dem Einlauf in den Einlauffinger eine Verengung des Strangführungskanals vorgenommen werden, um am Einlauf nicht ruckartig eine Querschnittsverengung vornehmen zu müssen.Another advantageous embodiment of the invention is characterized in that that the strand guide channel continuously narrows in the conveying direction. To this Way it is possible to pass through the tobacco rod through the Equalizer to reduce the cross-section of the tobacco rod. In the state technology are the fixed side walls of the tobacco channel in the conveying direction arranged slightly divergent. As a result it comes at the enema in the format under the so-called infeed finger, which wraps the tobacco rod introduces with a strip of wrapping material, to a relatively violent narrowing of the cross-section, which is problematic with regard to the running safety of the machine. thanks to the The cheek running according to the invention increases the running safety of the machine, because the tobacco rod is constantly guided from the side, carried along and light is compressed. Thanks to the invention, they can also be used in the prior art Reduce some of the shifts in the strand structure that can be observed. Consequently can - as mentioned before - one before entering the enema finger Constriction of the strand guide channel can be made in order not to at the inlet to suddenly have to narrow the cross-section.
Weiterhin ist es bevorzugt, wenn die mitlaufenden Seitenwände luftdurchlässig sind, so daß durch sie Luft angesogen und somit der geförderte Faserstrang an die Seitenwände angesaugt werden kann. Auf diese Weise läßt sich die Konturierung des derartig geförderten Stranges präzisieren.Furthermore, it is preferred if the moving side walls are air-permeable are so that air is sucked through them and thus the conveyed fiber strand to the Side walls can be sucked. In this way, the contouring of the strand thus promoted.
Eine weitere vorteilhafte Ausführungsform der Erfindung zeichnet sich dadurch aus, daß die Ausnehmungen in den Seitenwänden abwechselnd stärker und schwächer ausgebildet sind. Auf diese Weise läßt sich erreichen, daß die somit erzeugten Kopfverstärkungen beispielsweise am Filterende des Tabakstockes schwächer sind als am Brandende des Tabakstockes. In jedem Falle läßt sich somit dank der Erfindung individuell auf die Bedürfnisse der jeweilig herzustellenden Zigarette eingehen.Another advantageous embodiment of the invention is characterized in that that the recesses in the side walls alternately stronger and weaker are trained. In this way it can be achieved that the thus generated Head reinforcements, for example at the filter end of the tobacco rod, are weaker than at the end of the fire of the tobacco stick. In any case, thanks to the Invention individually tailored to the needs of the respective cigarette to be manufactured come in.
