Description

Die Erfindung betrifft eine Einrichtung zum Stopfen von Zigarettentabak in vorgefertigte Zigarettenhülsen, vorzugsweise Filter-Zigarettenhülsen, mit einem trichterförmigen, an seiner Mündung mit einer Tabakzerteil- und Dosiereinrichtung versehenen Tabak-Vorratsbehälter, einer unterhalb des Vorratsbehälters angeordneten Tabakstrang-Formeinrichtung, wobei die Formeinrichtung und die Dosiereinrichtung über eine Antriebsvorrichtung betätigbar sind und bei der ein seitlicher Auslaß für den geformten Tabakstrang vorgesehen ist, sowie ein Zigarettenhülsen-Füllrohr seitlich an den Tabakstrang-Auslaß angesetzt ist.The invention relates to a device for stuffing cigarette tobacco into prefabricated cigarette tubes, preferably filter-cigarette tubes, with a funnel-shaped tobacco storage container provided at its mouth with a tobacco cutting and dosing device, a tobacco rod molding device arranged below the storage container, the molding device and the Dosing device can be actuated by a drive device and in which a side outlet is provided for the shaped tobacco rod, and a cigarette tube filling tube is attached to the side of the tobacco rod outlet.

Bei derartigen Zigaretten-Stopfgeräten ist es erforderlich, aus einem feinfaserigen Tabakvorrat einen Strang zu formen und diesen in die Zigarettenhülse einzubringen. Dabei muß der in einem zunächst zusammenhängenden Knäuel vorliegende Zigarettentabak zerkleinert und anschließend zu einem wieder zusammenhängenden dünnen Strang geformt werden, um das Abbröckeln der Glut beim Rauchvorgang zu verhindern.In the case of such cigarette tamping devices, it is necessary to form a strand from a fine-fiber tobacco supply and to insert it into the cigarette tube. The cigarette tobacco present in an initially coherent ball must be crushed and then formed into a coherent, thin strand in order to prevent the embers from crumbling off during the smoking process.

Es sind manuell zu betätigende Zigaretten-Stopfgeräte bekannt, beispielsweise aus der US-A-35 09 887, bei denen der Tabakvorrat (Knäuel) zunächst von Hand entzerrt und portioniert - in Bezug auf die für eine einzelne Zigarette erforderliche Tabakmenge - in eine längliche, schalenförmige Formvorrichtung eingebracht wird. Anschließend wird eine Andruckschale auf den vorgeformten Tabakstrang gedrückt und der Tabak zu einem runden Tabakstrang zusammengepreßt. Mittels einer manuell zu betätigenden Hebeleinrichtung wird der vorgeformte Tabakstrang sodann in eine auf eine Halterungstülle aufgesteckte und durch ein Andruckglied festgehaltene Zigarettenhülse gedrückt.Manually operated cigarette tamping devices are known, for example from US-A-35 09 887, in which the tobacco supply (ball) is first rectified by hand and portioned - in relation to the amount of tobacco required for a single cigarette - into an elongated, bowl-shaped molding device is introduced. Then a pressure bowl is pressed onto the preformed tobacco rod and the tobacco is pressed into a round tobacco rod. By means of a manually operated lever device, the preformed tobacco rod is then pressed into a cigarette tube which is attached to a holder and held in place by a pressure element.

Bei diesen Geräten ist es jedoch zur Erzielung einen zusammenhängenden Tabakstranges erforderlich, die in das Gerät eingebrächte Tabakmenge genau zu portionieren und auch die Tabakfasern zusammenhängend manuell vorzuformen. Bei zu wenig eingebrachtem Tabak bzw. nicht zusammenhängenden Tabakfasern des Stranges kommt es häufig vor, daß beim Rauchvorgang die Glut von der Zigarette abfällt.With these devices, however, to achieve a coherent tobacco rod, it is necessary to precisely portion the amount of tobacco introduced into the device and to preform the tobacco fibers in a coherent manner manually. If too little tobacco is introduced or the tobacco fibers of the strand are not connected, it often happens that the embers fall off the cigarette during the smoking process.

Die dadurch entstehenden Brandgefahren und Ärgernisse infolge erloschener Zigaretten sind mannigfaltig, klar ersichtlich und sollen hier im einzelnen nicht näher erläutert werden. Ein weiterer Nachteil der bekannten Geräte ist darin zu sehen, daß zum Herstellen von Zigaretten vielfältige manuelle Vorgänge auszuführen sind, die die Herstellung einer größeren Anzahl, beispielsweise des Tagesbedarfs eines Rauchers, von optimal gestopften Zigaretten aufwendig und schwierig gestalten.The resulting fire risks and annoyances due to extinguished cigarettes are manifold, clearly visible and are not to be explained in detail here. Another disadvantage of the known devices can be seen in the fact that a variety of manual processes have to be carried out to produce cigarettes, which make the production of a larger number, for example the daily requirement f s of a smoker, of optimally stuffed cigarettes complex and difficult.

Aus der US-A-2 633 133 ist ein Zigarettenstopfgerät bekannt, das mit einem trichterförmigen Tabakvorratsbehälter versehen ist und wobei im unteren Bereich des Behälters eine Tabakzerteil-Einrichtung vorgesehen ist. Dabei wird bei dem bekannten Gerät der Tabak von einer mittels einer Handkurbel drehbaren Drahtspindel erfaßt und in ein seitlich an den Behälter angebrachtes Füllrohr transportiert. Auf dieses Füllrohr wird die zu füllende Zigaretten-Leerhülse aufgeschoben, wobei durch das Füllrohr hindurch Tabak in die Hülse bei Drehung der Spindel transportiert wird.From US-A-2 633 133 a cigarette stuffing device is known which is provided with a funnel-shaped tobacco storage container and wherein a tobacco cutting device is provided in the lower region of the container. In the known device, the tobacco is grasped by a wire spindle which can be rotated by means of a hand crank and is transported into a filling tube attached to the side of the container. The empty cigarette tube to be filled is pushed onto this filling tube, with tobacco being transported through the filling tube into the tube when the spindle rotates.

Beim Zerteilen des Tabaks ist oberhalb der Transportspindel im Vorratsbehälter eine drehbare Welle vorgesehen, die mit fingerartigen Ansätzen versehen ist, die zwischen beabstandeten federnden Zungen durchgreifen.When the tobacco is cut up, a rotatable shaft is provided in the storage container above the transport spindle, which shaft is provided with finger-like projections which engage between spaced resilient tongues.

Da der in den Vorratsbehälter eingebrachte Tabak jedoch oftmals relativ grobe Verunreinigungen/Beimengungen wie z. B. grobe Tabakfasern, Tabakstengel etc. enthält, kommt es bei dem bekannten Gerät häufig zu Blockierungen des Gerätes bzw. Verstopfungen am Füllrohreingang. Dieser Nachteil ist besonders gravierend, wenn ein Zigaretten-Stopfgerät nicht manuell (Handkurbel) - wie bei dem aus der US-A-2 633 133 bekannten Gerät - betätigt, sondern motorisch angetrieben werden soll und wenn dabei eine größere Anzahl von Zigarettenhülsen automatisch nacheinander gestopft werden soll. Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, unter Vermeidung der genannten Nachteile bekannter Anordnungen, ein Gerät zum Stopfen von Zigarettentabak in vorgefertigte Zigarettenhülsen, wobei ein kontinuierlich fest zusammenhängender Tabakstrang geformt und in die Zigarettenhülse eingeschoben wird, zu schaffen, bei dem ein manuelles Portionieren, Zerfasern und Vorsortieren des zu verarbeitenden Tabaks nicht erforderlich ist, und bei dem eine Tabakzerteil- und Dosiereinrichtung dahingehend ausgebildet ist, daß Verstopfungen bzw. Blockierungen des Gerätes auch bei mit groben Beimengungen versehenem Tabak mit Sicherheit vermieden werden. Diese Aufgabe wird dadurch gelöst, daß die Tabakzerteil- und Dosiereinrichtung in einer am unteren Ende des Vorratsbehälters ausgebildeten, schlitzförmigen Mündung angeordnet und als Messerwelle ausgebildet ist.However, since the tobacco introduced into the storage container is often relatively coarse impurities / admixtures such. B. contains coarse tobacco fibers, tobacco stems, etc., it often comes to blockages in the known device or blockages at the filling tube entrance. This disadvantage is particularly serious when a cigarette tamping device is not to be operated manually (hand crank) - as in the device known from US-A-2 633 133 - but is to be driven by a motor and when a large number of cigarette tubes are automatically tamped one after the other shall be. The present invention is therefore based on the object, while avoiding the aforementioned disadvantages of known arrangements, of creating a device for stuffing cigarette tobacco into prefabricated cigarette tubes, a continuously firmly connected tobacco rod being shaped and inserted into the cigarette tube, in which manual portioning, Shredding and pre-sorting of the tobacco to be processed is not necessary, and in which a tobacco cutting and dosing device is designed in such a way that blockages or blockages of the device can be avoided with certainty even with tobacco provided with coarse additives. This object is achieved in that the tobacco cutting and metering device is arranged in a slot-shaped mouth formed at the lower end of the storage container and is designed as a knife shaft.

Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Ansprüchen 2 bis 34 angegeben und näher erläutert. Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß ein Gerät zum Stopfen von Zigaretten geschaffen wurde, bei dem der Tabak praktisch ohne manuelle Vorbehandlung aus einer Tüte oder Dose in den Vorratsbehälter des Gerätes eingefüllt, im Gerät selbsttätig zerfasert und einer Tabakstrang-Formeinrichtung zugeleitet wird, in der ein fest zusammenhängender Tabakstrang geformt und automatisch in eine Zigarettenhülse eingeschoben wird.Further advantageous embodiments of the invention are specified in the dependent claims 2 to 34 and explained in more detail. The advantages achieved by the invention consist in particular in the fact that a device for stuffing cigarettes has been created in which the tobacco is poured into the storage container of the device practically without manual pretreatment, automatically defibrated in the device and fed to a tobacco rod shaping device is formed in which a tightly connected tobacco rod and is automatically inserted into a cigarette tube.

Der Antrieb des Gerätes erfolgt dabei vorzugsweise über einen einzigen elektrischen Motor, so daß nach dem Einfüllen des Tabaks und Ingangsetzen des Motors, eine rauchfertige, optimal gestopfte Zigarette aus dem Gerät ausgeschoben wird. Weitere vorteilhafte Ausgestaltungen der Erfindung sehen vor, daß auch eine größere Anzahl von Zigaretten automatisch, nacheinander erstellt werden kann.The device is preferably driven by a single electric motor, so that after the tobacco has been poured in and fed the engine, a smoke-ready, optimally stuffed cigarette is pushed out of the device. Further advantageous embodiments of the invention provide that even a larger number of cigarettes can be created automatically, one after the other.

Die in den Fig. 1, 2 und 3 dargestellte Einrichtung zum Stopfen von Zigarettentabak in Filterzigarettenhülsen ist der Übersichtlichkeit halber ohne ein äußeres Gehäuse dargestellt, wobei hier auch nur die zum Verständnis der vorliegenden Erfindung wesentlichen Teile zeichnerisch dargestellt sind.The device shown in FIGS. 1, 2 and 3 for stuffing cigarette tobacco in filter cigarette tubes is shown without an outer housing for the sake of clarity, only the parts essential for understanding the present invention being shown in the drawing.

Die Einrichtung besteht im wesentlichen aus dem trichterförmigen Vorrats- bzw. Einfüllbehälter 1, der Stiftwelle 2, dem Tabak-Vorratsraum 3, der Tabakstrang-Formeinrichtung 4, sowie dem Füllrohr 5.The device essentially consists of the funnel-shaped storage or filling container 1, the pin shaft 2, the tobacco storage room 3, the tobacco rod shaping device 4, and the filling pipe 5.

Im Durchlaßbereich zwischen Einfüllbehälter und Tabak-Vorratsraum ist ein Rundstabrost 6 vorgesehen, der aus den einzelnen mit gegenseitigem Abstand angeordneten Rundstäben 7 gebildet ist. Die Stiftwelle 2 ist unterhalb dieses Rundstabrostes angeordnet, so daß die Stifte 8 bei Drehung der Stiftwelle nacheinander durch die Zwischenräume 9 des Rundstabrostes hindurchgreifen, den im Einfüllbehälter befindlichen Tabak erfassen, und durch die Schlitze des Rostes in den Tabakvorratsraum transportieren. Dabei wird der zunächst gegebenenfalls in einem zusammenhängenden Knäuel vorliegende Tabak entzerrt, so daß anschließend im Tabak-Vorratsraum eine Tabakmenge in feinfaseriger Struktur vorliegt.In the passage area between the filling container and the tobacco storage room, a round bar grate 6 is provided, which is formed from the individual round bars 7 arranged at a mutual spacing. The pin shaft 2 is arranged below this round bar grate, so that the pins 8, when the pin shaft rotates, reach successively through the spaces 9 of the round bar grate, grasp the tobacco located in the filling container, and transport them through the slots of the grate into the tobacco storage room. The tobacco, which may initially be present in a coherent skein, is equalized, so that a quantity of tobacco with a fine fiber structure is subsequently present in the tobacco storage room.

Neben der Stiftwelle ist im Tabak-Vorratsraum ein Abstreifblech 10 angeordnet, das mit keilförmigen Schlitzen 11 versehen ist, durch die die Stifte der Stiftwelle bei deren Drehung hindurchbewegt werden und an den Stiften hängende Tabakfasern abgestreift werden. Tabakfasern, die einmal in den Tabak-Vorratsraum transportiert wurden, werden somit nicht wieder in den Vorratsbehälter zurückbefördert. Am Grunde des Tabak-Vorratsraumes 3, der als nach unten hin keilförmig zulaufender, länglicher Trichter ausgebildet ist, ist die Tabakstrang-Formeinrichtung 4 vorgesehen, die im wesentlichen aus einem halbschalenförmigen Formblech 12, sowie der darin drehbar angeordneten Transportfeder 13 besteht. Formblech 12 und die Trichterwandungen 14 können gegebenenfalls aus einem einstückigen Blechmaterial gebogen sein. Das Formblech 12 liegt dicht an der Transportfeder 13 an, d. h. die Transportfeder dreht sich in einer nach oben hin offenen Wanne.In addition to the pin shaft, a scraper plate 10 is arranged in the tobacco storage space, which is provided with wedge-shaped slots 11, through which the pins of the pin shaft are moved as they rotate and tobacco fibers hanging on the pins are stripped off. Tobacco fibers that were once transported to the tobacco storage room are therefore not returned to the storage container. At the bottom of the tobacco storage room 3, which is designed as an elongated funnel tapering towards the bottom, the tobacco rod shaping device 4 is provided, which essentially consists of a half-shell-shaped shaped plate 12 and the transport spring 13 rotatably arranged therein. The shaped sheet 12 and the funnel walls 14 can optionally be bent from a one-piece sheet material. The shaped plate 12 lies close to the transport spring 13, i. H. the transport spring rotates in a tub that is open at the top.

Der Tabak-Vorratsraum ist im unteren Bereich, in Verlängerung der Tabakstrang-Formeinrichtung mit einem seitlichen Auslaß 15 versehen, an den das Füllrohr 5 angesetzt ist. Dabei ragt das eine Ende der Transportfeder in das Füllrohr hinein und schließt mit dessen Vorderkante 16 ab.The tobacco storage room is provided in the lower region, in the extension of the tobacco rod shaping device, with a lateral outlet 15 to which the filling tube 5 is attached. One end of the transport spring protrudes into the filling tube and closes with its front edge 16.

Am wandseitigen Ende des Füllrohres befindet sich eine Andruckeinrichtung 17 für die Zigarettenhülse 18, die etwa 1/3 der auf das Füllrohr aufgeschobenen Zigarettenhülse überdeckt.At the wall end of the filling tube there is a pressure device 17 for the cigarette tube 18, which covers approximately 1/3 of the cigarette tube pushed onto the filling tube.

Weiterhin ist am Füllrohr-Anfang 16 eine Zigarettenhülsen-Formeinrichtung 19 angeordnet, die im wesentlichen aus einem Formstück mit einer zylindrischen Bohrung 20 und einer konischen Einführöffnung 21 besteht, wobei der Bohrungsdurchmesser dem Außendurchmesser der Zigarettenhülse entspricht. Durch diese Formeinrichtung werden die auf das Füllrohr aufzuschiebenden Zigarettenhülsen, die aufgrund des dünnen Papiermaterials der Zigarettenhülsen oftmals leicht deformiert, d. h. unrund, oval vorliegen, in eine präzise runde Form gebracht, so daß sie sich mühelos auf das Füllrohr aufschieben lassen.Furthermore, a cigarette tube shaping device 19 is arranged at the beginning of the filling tube 16, which essentially consists of a shaped piece with a cylindrical bore 20 and a conical insertion opening 21, the bore diameter corresponding to the outside diameter of the cigarette tube. By means of this shaping device, the cigarette tubes to be pushed onto the filling tube, which are often slightly deformed due to the thin paper material of the cigarette tubes, i. H. are out of round, oval, brought into a precise round shape so that they can be easily pushed onto the filling tube.

Der Antrieb von Stiftwelle 2 und Transportfeder 13 erfolgt vorzugsweise durch den Motor 22, wobei die Stiftwelle über ein Rädergetriebe 23 mit einer Drehgeschwindigkeit angetrieben wird, die vorzugsweise etwa 1,8 bis 2 mal größer ist als die Drehgeschwindigkeit der Transportfeder. Auf jeden Fall sind die beiden Geschwindigkeiten so aufeinander abgestimmt, daß gerade soviel Tabak in den Vorratsraum transportiert wird, wie auch von der Transportfeder erfaßt, zum Strang geformt und in die Zigarettenhülse geschoben wird.The pin shaft 2 and the transport spring 13 are preferably driven by the motor 22, the pin shaft being driven via a gear mechanism 23 at a rotational speed which is preferably approximately 1.8 to 2 times greater than the rotational speed of the transport spring. In any case, the two speeds are coordinated so that just as much tobacco is transported into the storage space as is also grasped by the transport spring, formed into a strand and pushed into the cigarette tube.

Gegebenenfalls kann vorgesehen sein, daß bei erstmaliger Inbetriebnahme der Einrichtung ein geringer Tabakvorrat in den Tabakvorratsraum 3 eingebracht wird, um auch zu Beginn des ersten Stopfvorganges sicherzustellen, daß genügend Tabakvorrat zum kontinuierlichen Formen des Tabakstranges im Vorratsraum vorhanden ist.If necessary, provision can be made for a small tobacco supply to be introduced into the tobacco storage room 3 when the device is started up for the first time, in order to ensure, even at the start of the first tamping process, that there is sufficient tobacco supply for the continuous shaping of the tobacco rod in the storage room.

Die einzelnen Bauelemente des Zigarettenstopfgerätes sind im vorliegenden Ausführungsbeispiel auf einer gemeinsamen Grundplatte 24 aufgebaut. Diese Anordnung ist hier nur als Beispiel für eine Ausführungsform zu sehen, Abwandlungen, ohne den Rahmen der Erfindung zu verlassen, sind ohne weiteres möglich, sollen hier jedoch nicht weiter erläutert werden.The individual components of the cigarette plug Devices are built on a common base plate 24 in the present embodiment. This arrangement is only to be seen here as an example of an embodiment; modifications are possible without departing from the scope of the invention, but are not to be explained further here.

Die in der Fig. 4 dargestellte Stiftwelle 2 besteht im wesentlichen aus einer runden Welle, in die die Stifte 8 derart längs einer Schraubenlinie 25 eingesetzt sind, daß sich bei Drehung der Stiftwelle jeweils nur ein Stift der Welle zwischen den Rundstäben 7 des Rundstabrostes 6, bzw. im jeweiligen Schlitz 11 des Abstreifbleches 10 befindet. Hierdurch wird ein gleichmäßiges Erfassen und Zerfasern des Tabaks erzielt, bei gleichzeitig geringem Kraftbedarf für den Antrieb der Stiftwelle.The pin shaft 2 shown in FIG. 4 essentially consists of a round shaft, into which the pins 8 are inserted along a helical line 25 such that when the pin shaft rotates, only one pin of the shaft is between the round bars 7 of the round bar grate 6, or in the respective slot 11 of the scraper plate 10. As a result, the tobacco is evenly gripped and frayed, while at the same time requiring little power to drive the pin shaft.

In der Fig. 6 ist die Transportfeder 13 vergrößert dargestellt und deren, für das Formen eines zusammenhängenden Tabakstranges wesentliche Merkmale werden nachfolgend erläutert. Die Transportfeder ist vorzugsweise aus einem scharfkantigen 4-kant-Material hergestellt und weist drei Hauptbereiche A, B und C auf.In Fig. 6, the transport spring 13 is shown enlarged and its essential for the formation of a coherent tobacco rod features are explained below. The transport spring is preferably made of a sharp-edged square material and has three main areas A, B and C.

Der Bereich « A ist zylindrisch ausgebildet und hat einen Durchmesser von ca. 10 mm. Dieser Bereich, der bei im Gerät eingesetzter Transportfeder in dem halbschalenförmigen Formblech 12 liegt, dient der ersten Tabakaufnahme bei sich drehender Transportfeder. Die Steigung S1 der Federwindungen in diesem Bereich beträgt ca. 5 mm. Hierdurch wird erreicht, daß die Tabakfasern leicht in die Windungen der Feder und somit in den Innenraum der Transportfeder eintreten können. Durch die relativ große Steigung in Verbindung mit dem großen Durchmesser wird vermieden, daß sich ein Hohlraum zwischen Transportfeder-Oberseite und dem oberhalb befindlichen Tabakvorrat bildet.The area «A is cylindrical and has a diameter of approx. 10 mm. This area, which lies in the half-shell-shaped molded sheet 12 when the transport spring is inserted in the device, is used for the first tobacco receptacle when the transport spring is rotating. The pitch S 1 of the spring turns in this area is approximately 5 mm. This ensures that the tobacco fibers can easily enter the windings of the spring and thus the interior of the transport spring. The relatively large slope in connection with the large diameter prevents a cavity from forming between the top of the transport spring and the tobacco supply located above.

Der Bereich « B » bildet die Einlaufzone in das Füllrohr 5. Hier nimmt der Federdurchmesser kontinuierlich von 10 mm auf ca. 5 mm ab. Die Länge dieses Bereiches beträgt etwa 10 mm. Durch diese Verjüngung und die Drehung der Transportfeder werden die Tabakfasern, in Verbindung mit der Füllrohrgeometrie dieses Bereiches (konisch-oval), in diesem Bereich zu einem zusammenhängenden Strang verbunden und vom Durchmesser her gesehen komprimiert.The area “B” forms the inlet zone into the filling tube 5. Here the spring diameter decreases continuously from 10 mm to approx. 5 mm. The length of this area is approximately 10 mm. As a result of this tapering and the rotation of the transport spring, the tobacco fibers, in connection with the filler tube geometry of this area (conical-oval), are connected in this area to form a coherent strand and are compressed in terms of diameter.

Der Bereich « C ist der Bereich, der im Inneren des zylindrischen Teils des Füllrohres vorgesehen ist. Der Federdurchmesser ist hier geringer als im Bereich A, nämlich im vorliegenden Beispiel ca. 5 mm. Auch die Steigung S2 der Federwindungen ist hier kleiner, nämlich nur 3 mm. Hierdurch wird erreicht, daß der im Bereich A zunächst nur lose vorgeformte und im Bereich B auf einen kleineren Durchmesser geformte Tabakstrang auch in Längsrichtung komprimiert wird, so daß ein fest zusammenhängender Tabakstrang geformt wird. Hierbei sei noch angeführt, daß bei dieser Ausführung der Innendurchmesser des Füllrohres etwa 7 mm beträgt, d. h. zwischen Transportfeder und Füllrohrwandung ist ein allseitiger Luftspalt von etwa 1 mm vorhanden.The area “C is the area which is provided in the interior of the cylindrical part of the filling tube. The spring diameter is smaller here than in area A, namely approx. 5 mm in the present example. The pitch S 2 of the spring turns is also smaller here, namely only 3 mm. This ensures that the tobacco rod which is initially only loosely preformed in region A and which is shaped to a smaller diameter in region B is also compressed in the longitudinal direction, so that a firmly connected tobacco rod is formed. It should also be mentioned that in this embodiment the inner diameter of the filling tube is approximately 7 mm, ie there is an all-round air gap of approximately 1 mm between the transport spring and the filling tube wall.

Zu den vorstehenden Maßangaben sei noch erläutert, daß diese sich auf ein Ausführungsbeispiel beziehen, bei dem Zigarettenhülsen verwendet werden, die einen Druchmesser von ca. 8 mm aufweisen. Jedoch ist die Erfindung nicht auf derartige Zigarettenhülsen beschränkt, sondern kann unter Beibehaltung des Prinzips auch ohne weiteres bei anderen Hülsendurchmessern Anwendung finden, wobei gegebenenfalls die angegebenen Maße an diese Abmessungen angepaßt werden müssen.It should also be explained in relation to the above dimensions that these relate to an exemplary embodiment in which cigarette tubes are used which have a diameter of approximately 8 mm. However, the invention is not limited to such cigarette tubes, but can also easily be used with other tube diameters while maintaining the principle, the specified dimensions possibly having to be adapted to these dimensions.

In der Fig. 7 ist das Füllrohr 5 dargestellt. Das Füllrohr besteht aus einem dünnwandigen Material, beispielsweise nichtrostendem Stahl, Messing, Bronze oder Kunststoff. Der Einlaufbereich 26 ist konisch-oval geformt, während der Hauptbereich 27 zylindrisch ausgebildet ist.7 shows the filling pipe 5. The fill tube is made of a thin-walled material, such as stainless steel, brass, bronze or plastic. The inlet area 26 has a conical-oval shape, while the main area 27 is cylindrical.

Der Endbereich 28 ist konisch-rund ausgeführt. Durch die konisch-ovale Gestaltung des Einlaufbereiches wird ein staufreier Einlauf des Tabakstranges in das Füllrohr erzielt. Der leicht konische Endbereich 28 ermöglicht ein leichtgängiges Aufgleiten (Aufschieben) der Zigarettenhülse auf das Füllrohr selbst. Weiterhin wird durch die konische Ausbildung des Endbereiches auch im Innendurchmesser des Füllrohres in diesem Bereich eine weitere Komprimierung des austretenden Tabakstranges erzielt, wodurch ein optimales Strangfließvorhalten und ein gleichmäßiger Vorschub des Tabakstranges erreicht wird.The end region 28 is conical and round. The conical-oval design of the inlet area ensures that the tobacco rod enters the filler pipe without jamming. The slightly conical end region 28 enables the cigarette tube to slide easily onto the filling tube itself. Furthermore, the conical design of the end region also results in a further compression of the emerging tobacco rod in the inner diameter of the filling tube in this region, as a result of which an optimal strand flow retention and a more uniform Feed of the tobacco rod is reached.

Nachfolgend wird der Füllvorgang einer Zigarettenhülse, d. h. der Arbeitsablauf der Einrichtung zum Stopfen von Zigarettentabak in Zigarettenhülsen zusammenhängend erläutert. Zunächst wird aus einer Tüte oder Vorratsdose der zu verarbeitende Zigarettentabak in den Einfüllbehälter 1 eingefüllt. Dabei ist es nicht erforderlich, den Tabak bis auf seine Einzelfasern zu zerkrümeln, zerpflücken, sondern es können, natürlich innerhalb gewisser Grenzen, auch zusammenhängende Knäuel eingefüllt werden. Anschließend wird eine Filter-Zigarettenhülse 18 auf das Füllrohr 5 vollständig aufgeschoben. Durch die Hülsen-Formeinrichtung 19, durch die die Zigarettenhülse dabei hindurchgeschoben wird, werden dabei gegebenenfalls oval verformte Zigarettenhülsen exakt rund geformt, so daß sie sich leichtgängig auf das Füllrohr aufschieben lassen. Eine Andruckeinrichtung 17 drückt in Endlage der Zigarettenhülse einen vorderen Bereich von etwa 1/3 der Zigarettenhülsenlänge gegen das Füllrohr und klemmt die Hülse leicht fest. Mittels einer hier nicht näher dargestellten Einstelleinrichtung ist diese Andruckkraft einstellbar, um die Stopffestigkeit der Zigarette, die von der Tabakbeschaffenheit (Struktur, Feuchte etc.) abhängig ist, individuell anpassen zu können. Sodann wird der Antriebsmotor 22 eingeschaltet. Das kann über geeignete Abfühleinrichtungen beim vollständigen Aufschieben und Festklemmen der Zigarettenhülse automatisch oder auch von Hand mittels Druckknopfschalter o. ä. erfolgen.In the following, the filling process of a cigarette tube, ie the work flow of the device for stuffing cigarette tobacco in cigarette tubes, is explained in a coherent manner. First of all, the cigarette tobacco to be processed is filled into the filling container 1 from a bag or storage container. It is not necessary to crumble the tobacco down to its individual fibers, but rather, of course, within certain limits, coherent balls can also be filled in. A filter-cigarette tube 18 is then completely pushed onto the filling tube 5. Due to the sleeve-forming device 19, through which the cigarette tube is pushed, oval-shaped cigarette tubes are optionally formed to be exactly round, so that they can be easily pushed onto the filling tube. In the end position of the cigarette tube, a pressure device 17 presses a front region of approximately 1/3 of the length of the cigarette tube against the filling tube and clamps the tube lightly. This pressure force can be adjusted by means of an adjusting device, not shown here, in order to be able to individually adjust the cigarette's resistance to stopping, which depends on the tobacco quality (structure, moisture, etc.). Then the drive motor 22 is turned on. This can be done automatically by means of suitable sensing devices when the cigarette tube is completely pushed on and clamped, or manually by means of a push button switch or the like. respectively.

Durch die Ingangsetzung des Motors 22 dreht sich nun die Stiftwelle 2, sowie auch die Transportfeder 13. Durch die drehende Stiftwelle wird der im Einfüllbehälter befindliche Tabak erfaßt und durch den Rundstabrost 6 hindurch in den Tabakvorratsraum 3 gefördert. Dabei wird der Tabak fein zerfasert, so daß der in den Vorratsraum gelangende Tabak hier in Form einzelner Tabakfasern vorliegt. Die Tabakfasern fallen dabei auf, bzw. in die Transportfeder, werden von dieser erfaßt und in deren Innenraum hineingewunden. Die Verwendung von 4-kant-Material für die Transportfeder hat sich als besonders günstig erwiesen, da hierdurch die Tabakfasern besser erfaßt und transportiert werden als bei aus Rundmaterial hergestellten Transportfedern.When the motor 22 is started, the pin shaft 2 and the transport spring 13 rotate. The rotating pin shaft detects the tobacco in the filling container and conveys it through the round bar grate 6 into the tobacco storage room 3. The tobacco is finely shredded so that the tobacco entering the store is here in the form of individual tobacco fibers. The tobacco fibers stand out, or in the transport spring, are grasped by this and wound into the interior thereof. The use of square-edged material for the transport spring has proven to be particularly favorable, since this enables the tobacco fibers to be gripped and transported better than with transport springs made from round material.

Durch die Steigung der Transportfederwindungen werden die Tabakfasern im Inneren der Feder zusammengedreht und vom Bereich A mit größerem Federdurchmesser in den Bereich C mit kleinerem Federdurchmesser transportiert. Dabei tritt, wie vorstehend schon im einzelnen erläutert, eine komprimierung des Tabaks und Formung eines fest zusammenhängenden Tabakstranges ein. Sobald der Tabakstrang aus dem Füllrohr austritt, an dessen Ende 28 er durch die konische Gestaltung des Füllrohres an dieser Stelle nochmals komprimiert wird, drückt der Tabakstrang gegen das Filterende der Zigarettenhülse, preßt mit fortschreitendem Tabakaustritt aus dem Füllrohr diesen in die Zigarettenhülse hinein und diese selbst auf dem Füllrohr nach vorn. Durch den Andruck der Andruckeinrichtung 17 wird erreicht, daß der Tabak im ersten Drittel des Füllbereiches fest in die Zigarettenhülse eingedrückt wird. Im weiteren Füllverlauf (restliche 2/3) ist der besondere Andruck der Zigarettenhülse an das Füllrohr nicht mehr erforderlich, da sich herausgestellt hat, daß die Festigkeit des weiterhin austretenden Tabakstranges genügend ist, so daß die Stopffestigkeit der Zigarette auch ohne weitere besondere Maßnahmen ausreichend ist. Die beschriebene Anordnung der Andruckeinrichtung hat sich als besonders vorteilhaft erwiesen um eine gleichmäßige Füllung der Zigarettenhülse zu erzielen.Due to the gradient of the transport spring coils, the tobacco fibers inside the spring are twisted and transported from area A with a larger spring diameter to area C with a smaller spring diameter. As already explained in detail above, the tobacco is compressed and a firmly connected tobacco rod is formed. As soon as the tobacco rod emerges from the filling tube, at the end 28 of which it is compressed again at this point by the conical design of the filling tube, the tobacco rod presses against the filter end of the cigarette tube and, as the tobacco emerges from the filling tube, presses it into the cigarette tube and the tube itself on the filling pipe to the front. The pressure of the pressure device 17 ensures that the tobacco is pressed firmly into the cigarette tube in the first third of the filling area. In the further filling process (remaining 2/3), the special pressure of the cigarette tube on the filling tube is no longer necessary, since it has been found that the strength of the tobacco rod which continues to escape is sufficient, so that the cigarette's resistance to stopping is sufficient even without further special measures . The arrangement of the pressure device described has proven to be particularly advantageous in order to achieve a uniform filling of the cigarette tube.

Bei fortschreitender Füllung der Zigarettenhülse wird diese allmählich vom Füllrohr heruntergeschoben, bis zum Schluß die vollständig gefüllte Zigarettenhülse am Füllrohrende abgenommen werden kann. Durch geeignete, hier jedoch nicht näher dargestellte Abfühleinrichtungen kann dieser Zeitpunkt erfaßt und der Antrieb abgeschaltet werden. Anschließend kann eine neue Zigarettenhülse auf das Füllrohr aufgeschoben und in gleicher Weise gefüllt werden.As the filling of the cigarette tube progresses, it is gradually pushed down from the filling tube until the completely filled cigarette tube at the end of the filling tube can be removed. This time can be detected and the drive can be switched off by suitable sensing devices, which are not shown in detail here. A new cigarette tube can then be pushed onto the filling tube and filled in the same way.

In den Fig. 8, 9, 10 ist eine Einrichtung zum Stopfen von Zigarettentabak in Zigarettenhülsen in modifizierter Form dargestellt und wird im folgenden näher beschrieben. Auch diese Einrichtung besteht im wesentlichen aus dem trichterförmigen Vorrats- bzw. Einfüllbehälter 1', dem Tabakvorratsraum 3', der Tabakstrang-Formeinrichtung 4' sowie dem Füllrohr 5'.8, 9, 10, a device for stuffing cigarette tobacco in cigarette tubes is shown in a modified form and is described in more detail below. This device also essentially consists of the funnel-shaped storage or filling container 1 ', the tobacco storage room 3', the tobacco rod shaping device 4 'and the filling tube 5'.

Im Durchlaßbereich 29 zwischen Einfüllbehälter 1' und Tabak-Vorratsraum 3' ist hier eine Messerwelle 30 vorgesehen. Die Welle ist mit spiralförmig angeordneten Schneidkanten 31, sowie in Drehrichtung der Welle gesehen vor den Schneidkanten eingeformten Tabak-AufnahmeAusnehmungen 32 versehen. Die Seitenwände 33 des unteren Endes des Einfüllbehälters im Bereich der Messerwelle sind verstellbar an der oberen Trichterwand befestigt, so daß der Druchlaßspalt zwischen Messerwelle und Seitenwand einstellbar ist.A knife shaft 30 is provided in the passage area 29 between the filling container 1 'and the tobacco storage space 3'. The shaft is provided with spirally arranged cutting edges 31 and tobacco receptacle recesses 32 formed in front of the cutting edges as seen in the direction of rotation of the shaft. The side walls 33 of the lower end of the filling container in the area of the knife shaft are adjustably attached to the upper funnel wall, so that the passage gap between the knife shaft and the side wall is adjustable.

Der Tabak-Vorratsraum 3' ist in seinem unteren Bereich mit einer rechteckigen, länglichen Wanne 34 versehen, die nach oben hin offen ist und in der die Tabakstrang-Formeinrichtung 4' angeordnet ist. Die Tabakstrang-Formeinrichtung besteht hier im wesentlichen aus einer zweiteiligen Federanordnung (siehe auch Fig. 13), wobei hier eine äußere zylindrische Feder 35 mit großem Durchmesser und großer Steigung der Federwindungen vorgesehen ist, in deren Innenraum sich eine innere zylindrische Feder 36 mit kleinerem Durchmesser und auch kleinerer Steigung der Federwindungen befindet. Der Durchmesser der äußeren Feder entspricht in etwa der Breite der Wanne 34 in der die Feder drehbar angeordnet ist, und die Länge der Feder entspricht der Länge der Wanne, d. h. der Breite des Tabak-Vorratsraumes. Die innere Feder 36 durchsetzt die äußere Feder in ganzer Länge und ragt auf der Füllrohrseite aus dieser heraus. Die Gesamtlänge der inneren Feder ist so bemessen, daß sie bei zusammengefügtem Gerät mit der Vorderkante des Füllrohres 5' abschließt oder gegebenenfalls auch geringfügig übersteht. Der Durchmesser dieser dünneren Feder entspricht dem Füllrohr-Innendurchmesser, so daß sie mit leichtem seitlichen Spiel in dem Füllrohr drehbar ist.The tobacco storage room 3 'is provided in its lower region with a rectangular, elongated trough 34 which is open at the top and in which the tobacco rod shaping device 4' is arranged. The tobacco rod shaping device here essentially consists of a two-part spring arrangement (see also FIG. 13), an outer cylindrical spring 35 having a large diameter and a large pitch of the spring windings being provided, in the interior of which there is an inner cylindrical spring 36 having a smaller diameter and also a smaller pitch of the spring windings. The diameter of the outer spring corresponds approximately to the width of the tub 34 in which the spring is rotatably arranged, and the length of the spring corresponds to the length of the tub, i. H. the width of the tobacco store. The inner spring 36 penetrates the entire length of the outer spring and protrudes out of the latter on the filling tube side. The total length of the inner spring is dimensioned such that when the device is assembled it closes with the front edge of the filler tube 5 'or, if necessary, also protrudes slightly. The diameter of this thinner spring corresponds to the inner diameter of the filler tube, so that it can be rotated in the filler tube with slight lateral play.

Die Feder 35 wie auch die Feder 36 sind aus scharfkantigem 4-kant-Material hergestellt, wobei vorzugsweise der Querschnitt des Federmaterials der größeren Feder größer als der Querschnitt des Federmaterials der dünneren Feder ist. (z. B. : Äußere Feder 35 hergestellt aus quadratischem Federdraht mit einer Kantenlänge von ca. 1,3 mm und innere Feder 36 hergestellt aus quadratischem Federdraht mit ca. 1 mm Kantenlänge).The spring 35 as well as the spring 36 are made of sharp-edged square material, the cross section of the spring material of the larger spring preferably being larger than the cross section of the spring material of the thinner spring. (e.g. outer spring 35 made of square spring wire with an edge length of approx. 1.3 mm and inner spring 36 made of square spring wire with approx. 1 mm edge length).

Beide Federn sind auf entsprechend ihren Durchmessern ausgebildete Ansätze der Antriebswelle 37 aufgeschoben und hier befestigt. Am gegenüberliegenden Ende kann vorgesehen sein, daß die größere Feder auf einem entsprechenden Ansatz 38 drehbar gelagert ist. Die Transportfedern 35, 36 und die Dosierwelle 30 sind auch bei dieser Ausbildung der Einrichtung über ein Rädergetriebe 23' von einem gemeinsamen Antriebselement (z. B. Motor 22') angetrieben.Both springs are pushed onto attachments of the drive shaft 37 which are designed in accordance with their diameters and are fastened here. At the opposite end it can be provided that the larger spring is rotatably mounted on a corresponding extension 38. In this embodiment of the device, the transport springs 35, 36 and the metering shaft 30 are also driven by a common drive element (for example motor 22 ') via a gear mechanism 23'.

Wie aus den Fig. 14, 15 ersichtlich ist das Füllrohr ebenfalls mit einem konischen Einlaufbereich 26' versehen, der hier jedoch vorzugsweise rechteckig ausgebildet ist und in den runden, zylindrischen Teil des Füllrohres kontinuierlich übergeht. Darüber hinaus ist das Füllrohr in seinem Innenbereich mit sich längserstreckenden Nuten 39 versehen.As can be seen from FIGS. 14, 15, the filling pipe is also provided with a conical inlet area 26 ', which, however, is preferably rectangular here and is in the round, cylindrical part of the filling tube passes continuously. In addition, the filling tube is provided with longitudinally extending grooves 39 in its inner region.

Wie vorstehend bereits erwähnt, ist der Transportfeder-Durchmesser des sich in das Füllrohr erstreckenden Teiles der Feder so bemessen, daß die Transportfeder mit seitlichem Spiel im Füllrohr drehbar ist. Dabei dienen die Nuten 39 in der Füllrohr-Innenwand der Verbesserung des Fließverhaltens des zu fördernden Tabakstranges. Eine geringe konische Anschrägung 28' des Füllrohrendes erleichtert das Aufschieben der Zigarettenhülsen auf das Füllrohr.As already mentioned above, the transport spring diameter of the part of the spring extending into the filling tube is dimensioned such that the transport spring can be rotated with lateral play in the filling tube. The grooves 39 in the filling tube inner wall serve to improve the flow behavior of the tobacco rod to be conveyed. A slight conical bevel 28 'of the filling tube end makes it easier to push the cigarette tubes onto the filling tube.

In der Ausführung gem. Fig. 8 ist weiterhin ein Schlitten 40 vorgesehen, der auf einer Gleitschiene 41 längsverschiebbar angeordnet ist. Der Schlitten weist eine Aufnahmewanne 42 mit einem Endanschlag 43 für Zigarettenhülsen auf, in der die Zigarettenhülse so geführt ist, daß ihre Achse mit der Achse des Füllrohres fluchtet. Die Verschiebung des Schlittens in Richtung auf das Füllrohr zu, zwecks Aufschiebung der Zigarettenhülse auf das Füllrohr, erfolgt entweder von Hand oder mittels eines hier nicht näher dargestellten motorischen Antriebes.In the execution acc. 8, a carriage 40 is also provided, which is arranged on a slide rail 41 so as to be longitudinally displaceable. The carriage has a receiving trough 42 with an end stop 43 for cigarette tubes, in which the cigarette tube is guided such that its axis is aligned with the axis of the filling tube. The carriage is displaced in the direction of the filling tube for the purpose of pushing the cigarette tube onto the filling tube either by hand or by means of a motor drive (not shown here).

Weiterhin ist auf dem Füllrohr 5' ein leicht verschiebbares Form- und Zentrierteil 44 vorgesehen. Das Form- und Zentrierteil ist in der Fig. 16 als Einzelteil dargestellt und besteht im wesentlichen aus einer ringförmigen Führungshülse 45, deren Bohrung 46 so bemessen ist, daß die Hülse auf dem Füllrohr leichtgängig verschiebbar ist. An der Hülse sind dünne, federnde Zungen 47 befestigt, die in Anfangsstellung des Form- und Zentrierteiles (Teil 44 ganz nach vorn geschoben, Hülse befindet sich jedoch noch auf dem Füllrohr) in einer konischen Spitze vor dem Füllrohr zusammenfedern. Mit dem Schlitten 40 ist eine Mitnahme-Einrichtung 48 für die zwangsweise Verschiebung des Form- und Zentrierteiles mechanisch gekuppelt, die die beabstandeten Anschläge 49 und 50 aufweist.Furthermore, an easily displaceable molding and centering part 44 is provided on the filling tube 5 '. The shaped and centering part is shown in FIG. 16 as an individual part and essentially consists of an annular guide sleeve 45, the bore 46 of which is dimensioned such that the sleeve can be moved easily on the filling tube. On the sleeve thin, resilient tongues 47 are attached, which spring together in a conical tip in front of the filling tube in the initial position of the shaped and centering part (part 44 pushed forward, sleeve is still on the filling tube). A driving device 48 for the forced displacement of the shaped and centering part, which has the spaced stops 49 and 50, is mechanically coupled to the carriage 40.

Zum Aufschieben der Zigarettenhülse 18 auf das Füllrohr wird der Schlitten 40 mit der darauf befindlichen Zigarettenhülse in Richtung auf das Füllrohr zu bewegt. Dabei taucht die aus den federnden Zungen des Form- und Zentrierteiles gebildete Spitze etwas in die Zigarettenhülsen-Öffnung ein und der Anschlag 50 der MitnahmeEinrichtung gelangt zur Anlage an der Hülse des Form- und Zentrierteiles. In weiterer Fortführung des Aufschiebevorganges werden die Zigarettenhülse und das Form- und Zentrierteil gleichzeitig nach rechts bewegt (bezogen auf Darstellung in Fig. 8, 9). Durch das weitere Aufgleiten des Form- und Zentrierteiles auf das Füllrohr, werden die federnden Zungen 47 durch das hindurchtretende Füllrohr nach außen gebogen und drücken die Zigarettenhülsen-Öffnung, in die sie etwas eintauchen, wie vorstehend bereits erläutert, in eine exakt runde Form. Beim weiteren Verschieben des Schlittens wird die Zigarettenhülse auf das Füllrohr aufgeschoben und das Form- und Zentrierteil gleichfalls bis zur rechten Endlage verschoben. Dabei befinden sich die Enden der Federzungen im vorderen Bereich der Zigarettenhülse, zwischen der Hülse und dem Füllrohr. Es versteht sich von selbst, daß die Federzungen-Enden äußerst dünn ausgebildet sind und in ihrer Form der Rundung der Zigarettenhülse bzw. des Füllrohres angepaßt sind. Um ein übermäßiges Aufweiten und eventuelles Einreißen der Papierhülse zu vermeiden, kann vorgesehen sein, daß das Füllrohr mit vertieften äußeren Längsnuten versehen ist, in die die Federzungen-Enden beim Aufschieben auf das Füllrohr eintauchen.To slide the cigarette tube 18 onto the filling tube, the carriage 40 with the cigarette tube located thereon is moved in the direction of the filling tube. The tip formed from the resilient tongues of the molded and centering part dips somewhat into the cigarette tube opening and the stop 50 of the entrainment device comes to rest on the sleeve of the molded and centering part. As the slide-on process continues, the cigarette tube and the shaped and centering part are simultaneously moved to the right (based on the representation in FIGS. 8, 9). By further sliding the molded and centering part onto the filling tube, the resilient tongues 47 are bent outwards through the filling tube passing through and press the cigarette tube opening, into which they are somewhat immersed, as already explained above, into an exactly round shape. When the carriage is moved further, the cigarette tube is pushed onto the filling tube and the shaped and centering part is also moved to the right end position. The ends of the spring tongues are located in the front area of the cigarette tube, between the tube and the filling tube. It goes without saying that the spring tongue ends are extremely thin and their shape is adapted to the curvature of the cigarette tube or the filling tube. In order to avoid excessive widening and possible tearing of the paper sleeve, it can be provided that the fill tube is provided with recessed outer longitudinal grooves into which the spring tongue ends dip when pushed onto the fill tube.

Nachdem die Zigarettenhülse nunmehr vollständig auf das Füllrohr aufgeschoben ist, wird der Antrieb der Tabakstrang-Formeinrichtung 4' in Gang gesetzt und der aus dem Füllrohr austretende Tabakstrang tritt in die Zigarettenhülse ein. Mit fortschreitender Füllung der Zigarettenhülse wird diese allmählich vom Füllrohr geschoben, wobei der Schlitten 40 gleichzeitig mit verschoben wird. Auch das Form- und Zentrierteil wird durch Angreifen des Anschlages 49 an der Hülse 44 mit in Richtung auf den Füllrohranfang zu verschoben.After the cigarette tube has now been pushed completely onto the filling tube, the drive of the tobacco rod shaping device 4 'is started and the tobacco rod emerging from the filling tube enters the cigarette tube. As the filling of the cigarette tube progresses, it is gradually pushed off the filling tube, the slide 40 being simultaneously displaced. The shaped and centering part is also moved towards the filling tube start by engaging the stop 49 on the sleeve 44.

Am Schlitten ist eine auf die Gleitschiene 41 wirkende einstellbare Bremsfeder 51 vorgesehen, wobei durch die justierbare Bremskraft die Stopffestigkeit des in die Zigarettenhülse eingebrachten Tabaks individuell eingestellt werden kann.An adjustable brake spring 51 acting on the slide rail 41 is provided on the slide, the stop resistance of the tobacco introduced into the cigarette tube being individually adjustable by the adjustable braking force.

Sobald die Zigarettenhülse vollständig gefüllt und dabei vollständig vom Füllrohr heruntergeschoben ist, wird der Antrieb der Tabakstrang-Formeinrichtung abeschaltet und gegebenenfalls kurzzeitig in entgegengesetzter Richtung in Betrieb gesetzt. Durch die Rückwärts-Drehung der Transportfeder 36 wird dabei der Tabakstrang am Füllrohranfang abgedreht und von der Zigarettenfüllung getrennt. Dabei hat sich herausgestellt, daß ein geringfügig über das Füllrohrende hervorstehendes Ende der Transportfeder 36 die Abtrennung des Tabakstranges günstig beeinflußt. Es steht nunmehr eine rauchfertige Zigarette zur Verfügung, auf deren vorderes Ende gegebenenfalls noch mittels einer magnetbetätigten Klopfeinrichtung geklopft wird, um eventuell überstehende Tabakfasern festzuklopfen. Nach der Entnahme der Zigarette vom Führungsschlitten 40 kann eine leere Zigarettenhülse auf den Schlitten gelegt werden und in vorstehend beschriebener Weise ebenfalls gefüllt werden.As soon as the cigarette tube is completely filled and pushed completely down from the filling tube, the drive of the tobacco rod shaping device is switched off and, if necessary, briefly put into operation in the opposite direction. By turning the transport spring 36 backwards, the tobacco rod is turned off at the beginning of the filling tube and separated from the cigarette filling. It has been found that an end of the transport spring 36 which projects slightly beyond the end of the filling pipe has a favorable effect on the separation of the tobacco rod. There is now a ready-to-smoke cigarette available, on the front end of which is tapped by means of a magnet-operated tapping device, if necessary, in order to knock on any protruding tobacco fibers. After the cigarette has been removed from the guide carriage 40, an empty cigarette tube can be placed on the carriage and can also be filled in the manner described above.

Obwohl die Zuführung von leeren Zigarettenhülsen und die Entnahme von fertigen Zigaretten manuell erfolgen kann, sei hier der Vollständigkeit halber noch erwähnt, daß eine Zuführeinrichtung zum automatischen Zuführen von Zigarettenhülsen aus einem Vorrat auf den Transportschlitten, sowie ein gleichfalls automatisches Abführen von fertigen Zigaretten vom Schlitten in einen Auffangbehälter vorgesehen werden kann, wobei der Antrieb dieser Zu- und Abführeinrichtungen über eine Getriebe-Verbindung vom Antriebsmotor 22, 22' oder auch mittels eines separaten Antriebmotors erfolgen kann und die Steuerung der einzelnen Abläufe durch Erfassung der jeweiligen Betriebszustände der Einrichtung mittels geeigneter Abfühleinrichtungen (Mikroschalter, Lichtschranken etc.) und elektrischer Verknüpfung und Steuerung des Arbeitsablaufes erfolgt.Although the supply of empty cigarette tubes and the removal of finished cigarettes can be done manually, for the sake of completeness it should also be mentioned here that a feed device for the automatic supply of cigarette tubes from a supply on the transport carriage, as well as an automatic removal of finished cigarettes from the slide in a collecting container can be provided, the drive of these feed and discharge devices being able to take place via a gear connection from the drive motor 22, 22 'or also by means of a separate drive motor and the control of the individual processes by recording the respective operating states of the device by means of suitable sensing devices (microswitches, light barriers, etc.) and electrically linking and controlling the workflow.

Alle Merkmale, die in der vorstehenden Beschreibung erwähnt und/oder in der Zeichnung dargestellt sind, sollen, sofern der bekannte Stand der Technik dies zuläßt, für sich allein oder in beliebigen Kombinationen oder Teilkombinationen als erfindungswesentlich angesehen werden, auch wenn sie in den Ansprüchen nicht enthalten sind.All the features mentioned in the above description and / or shown in the drawing should, insofar as the known prior art permits, be regarded as essential to the invention on their own or in any combinations or partial combinations, even if they are not in the claims are included.
