Abstract

The device for filling pre-formed cigarette sleeves, especially filter cigarette sleeves, has a tobacco compression chamber (14) possessing a filling aperture (13), in which tobacco introduced through the filling aperture (13) can be compressed by means of a compression bar (17) which can be moved transversely to the longitudinal direction of the tobacco compression chamber (14) to form a tobacco rod (10), a socket onto which the cigarette sleeve can be fitted, a clamping device for retaining the cigarette sleeve on the socket, and an ejector (25) for ejecting the tobacco rod (10) from the compression chamber (14) into the cigarette sleeve. In order to prevent the projection of tobacco residues from the filling aperture of the tobacco compression chamber, the filling aperture (13) of the tobacco compression chamber (14) is assigned a separate lid (1), the closing movement of which precedes the movement of the compression bar (17) in the compression direction. Preferably, the tobacco rod (10) is over-compressed before ejection from the compression chamber (14). Moreover, the cigarette sleeve is diametrally clamped on the socket during the filling process. <IMAGE>

Description

Die Erfindung betrifft eine Vorrichtung zum Stopfen vorgefertigter Zigarettenhülsen, insbesondere Zigarettenfilterhülsen, mit Rauchtabak, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a device for plugging prefabricated cigarette tubes, in particular cigarette filter tubes, with smoking tobacco, according to the preamble of claim 1.

Eine derartige Vorrichtung ist beispielsweise aus der DE-A-2 139 242 bekannt, die eine längliche Preßkammer aufweist, welche einerseits von einem etwa halbrunden festen Wandteil und andererseits von einer entgegengesetzt halbrunden Fläche eines bewegbaren Preßbalkens begrenzt ist, mittels dem die Preßkammer nach Befüllen mit Tabak unter Herstellung eines strangartigen Tabakvorrats verschließbar ist. Am einen stirnseitigen Ende der Preßkammer ist eine Aufstecktülle zum Ansetzen und Aufstecken einer leeren Zigarettenhülse vorgesehen. Am entgegengesetzten Ende wird die Preßkammer durch einen kolbenartigen Tabak-Ausstoßschieber begrenzt, mittels dem der Tabakvorrat aus der Preßkammer in die Zigarettenhülse überführt werden kann. Zur Gewährleistung der Funktionssicherheit kann darüber hinaus am wirksamen Ende des Ausstoßschiebers noch ein halbschalenförmiger Löffel befestigt sein, der die Überführung des Tabakvorrats aus der Preßkammer in die Zigarettenhülse unter gleichzeitiger Erhaltung der Stabilität derselben unterstützt bzw. auch erst ermöglicht.Such a device is known, for example, from DE-A-2 139 242, which has an elongated press chamber which is delimited on the one hand by an approximately semicircular fixed wall part and on the other hand by an opposite semicircular surface of a movable press bar, by means of which the press chamber can be filled after being filled Tobacco is closable to produce a strand-like tobacco supply. At one end of the press chamber, a plug-in nozzle is provided for attaching and plugging in an empty cigarette tube. At the opposite end, the compression chamber is delimited by a piston-like tobacco ejection slide, by means of which the tobacco supply can be transferred from the compression chamber into the cigarette tube. To ensure functional reliability, a half-shell-shaped spoon can also be attached to the effective end of the ejection slide, which supports or enables the transfer of the tobacco supply from the press chamber into the cigarette tube while maintaining the stability thereof.

Diese bekannte Vorrichtung hat sich in der Praxis mehr oder weniger gut bewährt. Es haftet ihr jedoch der Nachteil an, daß das Überführen des Tabaks aus der Preßkammer in die Zigarettenpapierhülse nicht ausreichend befriedigend gelöst ist. Unter anderem ist nachteilig, daß der Benutzer beim Befüllen der Tabakpreßkammer stets darauf achten muß, daß möglichst wenig Tabakfasern über den Rand der Füllöffnung vorstehen, da sehr häufig ein nicht unbeachtlicher Teil der vorstehenden Tabakfasern bei der weiteren Handhabung zwischen Preßbalken und der diesem gegenüberliegenden Kante der Füllöffnung eingeklemmt wird, wodurch ein funktionssicheres Ausstoßen des Tabakstrangs aus der Preßkammer und Uberführung desselben in die Zigarettenhülse nicht mehr gewährleistet ist. Die eingeklemmten Tabakfasern behindern das Ausstoßen des Tabakstrangs mitunter derart, daß dieser innerhalb der Tabakpreßkammer in Längsrichtung gestaucht wird mit der Folge, daß die Zigarettenhülse entweder nur unvollständig gefüllt oder beim Überführen des gestauchten und dementsprechend hoch komprimierten Tabakvorrats von der Aufstecktülle losgerissen wird, und zwar meist unter Aufplatzen der Zigarettenhülse und entsprechendem Verbröseln des ausgestoßenen Tabaks. Diesem Problem versuchte man bislang dadurch zu begegnen, daß die obere Kante des Preßbalkens als Schneide ausgebildet ist, so daß überstehende Tabakfasern beim Verpressen des Tabaks abgetrennt werden. Die entsprechenden Maßnahmen haben sich jedoch bis heute nicht ausreichend bewährt. Dies liegt nicht zuletzt an den bestehenden Toleranzen sowie üblicherweise verwendeten Werkstoffen für Gehäuse einerseits und Preßbalken andererseits.This known device has more or less proven itself in practice. However, it suffers from the disadvantage that the transfer of the tobacco from the press chamber into the cigarette paper tube is not adequately solved. Among other things, it is disadvantageous that the user must always make sure when filling the tobacco press chamber that as little tobacco fibers as possible protrude beyond the edge of the filling opening, since very often a not inconsiderable part of the above tobacco fibers during further handling between the press beam and the edge thereof opposite Filling opening is clamped, whereby a reliable ejection of the tobacco rod from the press chamber and transferring the same into the cigarette tube is no longer guaranteed. The jammed Tobacco fibers sometimes hinder the ejection of the tobacco rod in such a way that it is compressed in the longitudinal direction within the tobacco press chamber, with the result that the cigarette tube is either only incompletely filled or is torn from the plug-in nozzle when the compressed and accordingly highly compressed tobacco supply is transferred, usually with bursting the cigarette tube and correspondingly crumbling the ejected tobacco. So far, attempts have been made to counter this problem by designing the upper edge of the press beam as a cutting edge, so that protruding tobacco fibers are separated when the tobacco is pressed. However, the corresponding measures have not yet proven themselves sufficiently. This is not least due to the existing tolerances and the materials commonly used for the housing on the one hand and the press beam on the other.

Des weiteren ist in der FR-A-545 756 eine Vorrichtung zum Stopfen vorgefertigter Zigarettenhülsen beschrieben. Dabei wird die längliche Preßkammer durch zwei halb-zylindrische Ausnehmungen gebildet, die in zwei zu- bzw. auseinanderbewegbaren Formteilen jeweils stirnseitig benachbart angeordnet sind. Der in die Zigarettenhülse einzubringende Tabak soll auf diese Weise zu einem Tabakstrang formgerecht verpreßt werden. Die Schließbewegung der beiden Formteile eilt dabei der Bewegung des Preßbalkens voraus.Furthermore, a device for plugging prefabricated cigarette tubes is described in FR-A-545 756. The elongated press chamber is formed by two semi-cylindrical recesses, which are each arranged adjacent to one another on the end face in two mold parts which can be moved toward and away from one another. In this way, the tobacco to be introduced into the cigarette tube should be pressed into a tobacco rod in the correct shape. The closing movement of the two molded parts precedes the movement of the press beam.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, mit einfachen Mitteln die Funktionssicherheit von Stopfgeräten der hier fraglichen Art erheblich zu verbessern, wodurch auch die Handhabung erheblich erleichtert wird.The present invention has for its object to significantly improve the functional reliability of tamping devices of the type in question here by simple means, which also makes handling considerably easier.

Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.This object is achieved by the characterizing features of claim 1.

Durch den erfindungsgemäßen Deckel wird sichergestellt, daß der in die Tabakpreßkammer eingefüllte Tabak sich vor dem Verpressen praktisch vollständig innerhalb der Preßkammer befindet. Der Anteil vorstehender Tabakfasern wird auf ein Minimum reduziert mit der Folge einer entsprechend erhöhten Funktionssicherheit im Vergleich zum oben erörterten Stand der Technik. Dabei ist der erfindungsgemäße Deckel parallel zum Preßbalken hin- und herbewegbar gelagert und mit der mit dem Preßbalken verbundenen Betätigungseinrichtung derart gekoppelt, daß die Bewegung des Preßbalkens in Preßrichtung erst dann beginnt, wenn der Deckel sich in Füllöffnungs-Schließstellung befindet. Damit werden durch den Deckel überstehende Tabakreste in die noch erweiterte Tabakpreßkammer regelrecht "hineingerollt", so daß sich der gesamte Tabak praktisch vollständig innerhalb der Tabakpreßkammer befindet, bevor die Verpressung desselben zu dem zu überführenden Tabakstrang erfolgt. Gleichzeitig wird hierdurch erreicht, daß durch herkömmliche Betätigung der dem Preßbalken zugeordneten Handhabe sowohl die erfindungsgemäße Schließ- und Öffnungsbewegung des Deckels als auch die Hin- und Herbewegung des Preßbalkens erhalten wird.The lid according to the invention ensures that the tobacco filled into the tobacco press chamber is practically completely inside the press chamber before being pressed. The proportion of the above tobacco fibers is kept to a minimum reduced with the consequence of a correspondingly increased functional reliability compared to the prior art discussed above. The cover according to the invention is mounted so that it can be moved back and forth parallel to the press beam and is coupled to the actuating device connected to the press beam in such a way that the movement of the press beam in the press direction only begins when the cover is in the fill-open-closed position. In this way, tobacco residues protruding through the lid are literally "rolled" into the tobacco press chamber, which is still enlarged, so that the entire tobacco is practically completely inside the tobacco press chamber before the same is pressed to the tobacco rod to be transferred. At the same time, this ensures that both the closing and opening movement of the cover according to the invention and the back and forth movement of the press beam is obtained by conventional actuation of the handle assigned to the press beam.

Konkret sind zu diesem Zweck entsprechende Steuerkurven entweder am Preßbalken und Deckel oder an der Betätigungshandhabe für den Preßbalken und/oder den Ausstoßschieber vorgesehen, z. B. entsprechend den Ansprüchen 2 und 3.Specifically, corresponding control curves are provided for this purpose either on the press beam and cover or on the actuating handle for the press beam and / or the ejection slide, for. B. according to claims 2 and 3.

Um das erwähnte "Hineinrollen" überstehender Tabakreste in die noch erweiterte Tabakpreßkammer zu begünstigen, ist die freie bzw. der Preßkammer zugewandte Vorderkante des Deckels preßkammerseitig abgeschrägt unter gleichzeitiger Ausbildung einer messerartigen Schneide, die mit der gegenüberliegenden Kante der Füllöffnung nach Art einer Schere zusammenwirkt. Durch diese konstruktive Maßnahme werden noch vereinzelt vorstehende Tabakfasern beim Schließen der Füllöffnung abgetrennt, so daß sichergestellt ist, daß das Ausstoßen des verpreßten Tabakstrangs aus der Tabakpreßkammer durch eingeklemmte Tabakfasern nicht behindert wird.In order to favor the "rolling in" of protruding tobacco residues into the still enlarged tobacco compression chamber, the free or the compression chamber facing front edge of the cover is chamfered on the compression chamber side with simultaneous formation of a knife-like cutting edge which interacts with the opposite edge of the filling opening in the manner of a pair of scissors. This constructive measure still separates protruding tobacco fibers when the filling opening is closed, so that it is ensured that the ejection of the compressed tobacco rod from the tobacco compression chamber is not hindered by pinched tobacco fibers.

In Kombination mit der vorgenannten Konstruktion haben sich die Maßnahmen nach Anspruch 6 und/oder 7 als besonders vorteilhaft erwiesen. Durch die vorgeschlagene Überkompression des Tabaks in der Tabakpreßkammer und der Entlastung des verpreßten Tabakstrangs zum Ausstoßen aus der Tabakpreßkammer auf Normalmaß oder geringfügig darunter ist es möglich, auf den eingangs erwähnten Löffel am ausstoßseitigen Ende des Ausstoßschiebers zu verzichten. Dabei muß bedacht werden, daß es sich bei dem erwähnten Löffel um ein äußerst filigranes Bauteil handelt, welches bei ungeschickter Handhabung leicht bricht und auch zu Verletzungen des Benutzers führt. Bei sehr feuchtem Tabak besteht sogar die Gefahr, daß bei der Rückbewegung des Ausstoßschiebers durch den Löffel Tabak aus der Zigarettenhülse wieder herausgezogen wird. Durch die erfindungsgemäße Überkompression des Tabaks kann also auf den erwähnten Löffel verzichtet werden. Der Tabakstrang läßt sich problemlos ohne Löffel, d. h. nur mittels des Ausstoßschiebers bzw. -Stößels in die Zigarettenpapierhülse überführen. Die Erfindung soll sich auch auf das beschriebene Verfahren zur Herstellung eines Tabakstrangs innerhalb einer Tabakpreßkammer beziehen, bei dem zunächst eine Überkompression des Tabakstrangs erfolgt derart, daß der Querschnitt desselben kleiner ist als der Querschnitt des Tabakaufnahmeraums der angesetzten Zigarettenhülse, um dann unmittelbar vor dem oder wenigstens beim Ausstoßen des Tabakstrangs diesen radial zu entlasten, so daß sein Querschnitt Normalmaß annimmt, vorzugsweise nur noch geringfügig kleiner ist als der freie Querschnitt des Tabakaufnahmeraums der angesetzten Zigarettenhülse. Dann kann der Tabakstrang ohne Löffel, d. h. nur mittels eines stumpfen Ausstoßschiebers bzw. -Stößels in den Tabakaufnahmeraum angesetzten Zigarettenhülse überführt werden.In combination with the aforementioned construction, the measures according to claim 6 and / or 7 have proven to be particularly advantageous. Due to the proposed over-compression of the tobacco in the tobacco press chamber and the relief of the compressed tobacco rod for ejection from the tobacco press chamber to normal dimensions or slightly below it is possible to dispense with the aforementioned spoon at the ejection end of the ejection slide. It must be borne in mind that the spoon mentioned is an extremely filigree component which breaks easily when handled improperly and also leads to injuries to the user. In the case of very moist tobacco, there is even the danger that tobacco will be pulled out of the cigarette tube again when the ejection slide moves back through the spoon. The over-compression of the tobacco according to the invention means that the spoon mentioned can be dispensed with. The tobacco rod can be easily transferred into the cigarette paper tube without a spoon, ie only by means of the ejection slide or pestle. The invention is also intended to relate to the described method for producing a tobacco rod within a tobacco press chamber, in which the tobacco rod is first over-compressed in such a way that the cross section of the rod is smaller than the cross section of the tobacco receiving space of the attached cigarette tube, and then immediately before or at least radially relieve the tobacco rod when it is ejected, so that its cross-section assumes normal dimensions, and is preferably only slightly smaller than the free cross-section of the tobacco-receiving space of the attached cigarette tube. Then the tobacco rod can be transferred without a spoon, ie only by means of a blunt ejection slide or tappet, into the cigarette tube attached to the tobacco receiving space.

Schließlich ist auch die Vorrichtung nach einem der Ansprüche 8 bis 10 von Bedentung. Beim Technik wird die Zigarettenhülse auf der Tülle nur einseitig geklemmt mit der Folge, daß beim Überführen eines relativ prallen Tabakstrangs sich die Zigarettenpapierhülse von der Tülle losreißt unter entsprechender Beschädigung im Klemmbereich. Durch diametrale Klemmung wird diese Gefahr auf ein Minimum reduziert. Die Ausschußrate wird entsprechend vermindert. Eine besonders schonende Behandlung der geklemmten Zigarettenpapierhülse wird durch die Maßnahme nach Anspruch 10 erreicht.Finally, the device according to one of claims 8 to 10 is also essential. In technology, the cigarette tube is only clamped on one side with the result that when a relatively bulky tobacco rod is transferred, the cigarette paper tube tears off the tube with corresponding damage in the clamping area. This risk is reduced to a minimum by diametrical clamping. The reject rate is reduced accordingly. A particularly gentle treatment of the clamped cigarette paper tube is achieved by the measure according to claim 10.

Zunächst soll anhand der Fig. 3a eine Ausführungsform für eine Vorrichtung zum Stopfen vorgefertigter Zigarettenhülsen , insbesondere Zigarettenfilterhülsen, mit Rauchtabak näher erläutert werden. Diese Vorrichtung umfaßt ein Gehäuse, welches aus einen Gehäuseunterteil 11 und einem Gehäuseoberteil 12 besteht. Im Gehäuseoberteil ist eine längliche Öffnung, nämlich Tabak-Füllöffnung 13, vorgesehen, die in eine Tabakpreßkammer 14 mündet. Die Preßkammer 14 wird einerseits von einem halbrunden Wandteil 40 und andererseits von einer entgegengesetzt halbrunden Fläche 16 eines waagerecht verschiebbaren Preßbalken 17 begrenzt. Der innere Wandteil 40 gehört zu einer der Preßkammer 14 zugeordneten äußeren Seitenwand 41, die als Doppelwand ausgebildet ist und deren äußerer Wandteil 42 in Anschlagrichtung gegenüber dem inneren Wandteil 40 verschiebbar ausgebildet ist. Zu diesem Zweck weist der äußere Wandteil 42 einen Ansatz 43 auf, der einen Längsschlitz 44 im inneren Wandteil 40 durchragt und in diesem gleitend gelagert ist. Der Ansatz 43 trägt einen stößelartigen Ausstoßschieber 25. Der Wandteil 42 und der Ausstoßschieber 25 bilden ein integrales, d. h. gemeinsam in Längsrichtung der Tabakpreßkammer 14 hin- und herverschiebbares Bauteil. Ferner ist der äußere Wandteil 42 mittels einer hinterschnittenen Führung 46 mit dem Gehäuseunterteil 11 unter Ausbildung einer Geradführung verbunden. Auf der Oberseite des äußeren Wandteils 42 ist ein Griff 29 angeordnet. Das dem Wandteil 16 diametrale Ende 20 des Preßbalkens 17 ist mit einem Hebel 21 gekoppelt, welcher zugleich als Handhabe 23 ausgebildet ist. Diese kann z. B. als Formspritzteil aus Kunststoff hergestellt sein. Die Handhabe 23 ist um eine horizontale Achse verschwenkbar gelagert, welche durch seitlich an der Handhabe 23 angeformte Lagerzapfen 22 definiert ist. Diese Lagerzapfen 22 sind in halbschalenförmigen Lagerschalen 45 drehbar gelagert, wobei sie in den Lagerschalen 45 durch einen Vorsprung 39 an der Innenseite das Gehäuseoberteils 12 gehalten werden.First, an embodiment for a device for plugging prefabricated cigarette tubes, in particular cigarette filter tubes, with smoking tobacco is to be explained in more detail with reference to FIG. 3a. This device comprises a housing which consists of a lower housing part 11 and an upper housing part 12. In the upper part of the housing there is an elongated opening, namely tobacco filling opening 13, which opens into a tobacco pressing chamber 14. The pressing chamber 14 is delimited on the one hand by a semicircular wall part 40 and on the other hand by an oppositely semicircular surface 16 of a horizontally displaceable pressing bar 17. The inner wall part 40 belongs to an outer side wall 41 assigned to the press chamber 14, which is designed as a double wall and the outer wall part 42 of which can be displaced in the stop direction with respect to the inner wall part 40 is trained. For this purpose, the outer wall part 42 has a shoulder 43 which extends through a longitudinal slot 44 in the inner wall part 40 and is slidably mounted therein. The extension 43 carries a plunger-like ejection slide 25. The wall part 42 and the ejection slide 25 form an integral component, that is to say which can be pushed back and forth together in the longitudinal direction of the tobacco compression chamber 14. Furthermore, the outer wall part 42 is connected to the lower housing part 11 by means of an undercut guide 46 to form a straight guide. A handle 29 is arranged on the upper side of the outer wall part 42. The end 20 of the press beam 17 which is diametrical to the wall part 16 is coupled to a lever 21, which is at the same time designed as a handle 23. This can e.g. B. as a molded part made of plastic. The handle 23 is mounted so as to be pivotable about a horizontal axis, which is defined by bearing pins 22 formed laterally on the handle 23. These journals 22 are rotatably supported in half-shell-shaped bearing shells 45, wherein they are held in the bearing shells 45 by a projection 39 on the inside of the upper housing part 12.

Am diametralen Ende 20 des Preßbalken 17 sind im axialen Abstand voneinander zwei L-förmige Wangen 24 angeformt, an deren einander zugewandten Innenseiten jeweils L-förmige Steuernuten 2 ausgebildet sind, in die seitlich an der Handhabe 23 angeformte Führungszapfen 6 hineinragen, wobei die beiden Führungszapfen 6 jeweils an den beiden Außenseiten der seitlichen Begrenzungswände der Handhabe 23 ausgebildet sind. An den Innenseiten der seitlichen Begrenzungswände der Handhabe 23 sind jeweils mit den Führungszapfen 6 fluchtend ebenfalls Führungszapfen angeformt. Diese korrespondieren mit einer jeweils bogenförmigen Steuernut 3, die jeweils an der Außenseite von zwei ebenfalls im axialen Abstand voneinander, jedoch zwischen den beiden bereits erwähnten L-förmigen Wangen 24 angeordneten Wangen 18 ausgebildet sind, die Bestandteil eines Zwischengehäuseoberteils 12 und Preßbalkens 17 hin- und herverschiebbaren Deckels 1 sind. Die Steuernuten 2 und 3 sind so ausgebildet und relativ zueinander angeordnet, daß bei Betätigung der Handhabe 23 in Preßrichtung (Pfeil 19) die Füllöffnung 13 der Tabakpreßkammer 14 durch den Deckel 1 verschlossen wird derart, daß die Schließbewegung des Deckels der Bewegung des Preßbalkens 17 in Preßrichtung voreilt. Vorzugsweise ist die Ankoppelung des parallel zum Preßbalken 17 hin- und herbewagbaren Deckels 1 an der Handhabe 23 so, daß die Bewegung des Preßbalkens 17 in Preßrichtung erst dann beginnt, wenn der Deckel 1 sich in Füllöffnungs-Schließstellung entsprechend Fig. 2 befindet. Um dies zu erreichen, ist bei der Ausführungsform nach Fig.3a die L-förmige Steuernut 2 vorgesehen, wobei der kürzere Schenkel sich im Abstand von Preßbalken 17 etwa parallel zu dessen Bewegungsrichtung erstreckt, und zwar von der Preßkammer 14 weggerichtet. Des weiteren ist die lichte Weite des oberen Horizontalschenkels der Steuernut 2 größer als der Außendurchmesser des zugeordneten Zapfens 6, so daß bei Verschwenken der Handhabe 23 in Preßrichtung 19 ausgehend von der Füllstellung der Führungszapfen 6 im oberen Horizontalschenkel der Steuernut 2 zunächst wirkungslos bleibt mit der Folge, daß der Preßbalken 17 in seiner zurückgezogenen Stellung entsprechend Fig. 3a verharrt. Die innenseitig an der Handhabe 23 angeformten, jeweils mit den Zapfen 6 fluchtenden Zapfen korrespondieren jedoch bereits von Anfang an mit den dem Deckel 1 zugeordneten Steuernuten 3, so daß der Deckel 1 ohne Verzögerung in Schließrichtung bewegt wird mit der Folge, daß die Füllöffnung 13 bereits vollständig verschlossen ist, bevor der Preßbalken 17 wirksam wird. Der beschriebene Bewegungsablauf ist anhand der Fig. 1 bis 3 nachvollziehbar. Beim Öffnen der Tabakpreßkammer erfolgt der Bewegungsablauf genau umgekehrt d. h. der Deckel 1 eilt dem Preßbalken 17 nach.At the diametrical end 20 of the press beam 17, two L-shaped cheeks 24 are formed at an axial distance from one another, on the mutually facing inner sides of which L-shaped control grooves 2 are formed, into which protruding guide pins 6 formed on the side of the handle 23, the two guide pins 6 are each formed on the two outer sides of the lateral boundary walls of the handle 23. On the inner sides of the lateral boundary walls of the handle 23, guide pins are also formed in alignment with the guide pins 6. These correspond to a respective arcuate control groove 3, each of which is formed on the outside of two cheeks 18, which are also arranged at an axial distance from one another, but between the two already mentioned L-shaped cheeks 24 of an intermediate housing upper part 12 and press bar 17 are push-to-slide cover 1. The control grooves 2 and 3 are designed and arranged relative to one another such that when the handle 23 is actuated in the pressing direction (arrow 19), the filling opening 13 of the tobacco pressing chamber 14 is closed by the cover 1 in such a way that the closing movement of the cover corresponds to the movement of the press beam 17 in Press direction advanced. Preferably, the coupling of the cover 1, which can be reciprocated parallel to the press beam 17, to the handle 23 is such that the movement of the press beam 17 in the pressing direction only begins when the cover 1 is in the fill opening-closed position according to FIG. 2. To achieve this, the L-shaped control groove 2 is provided in the embodiment according to FIG. 3a, the shorter leg extending at a distance from the press beam 17 approximately parallel to its direction of movement, namely directed away from the press chamber 14. Furthermore, the clear width of the upper horizontal leg of the control groove 2 is larger than the outer diameter of the associated pin 6, so that when pivoting the handle 23 in the pressing direction 19 starting from the filling position of the guide pin 6 in the upper horizontal leg of the control groove 2 initially remains ineffective, with the result that the press beam 17 remains in its retracted position according to Fig. 3a. The molded on the inside of the handle 23, each aligned with the pin 6 but correspond from the start with the control grooves 3 assigned to the cover 1, so that the cover 1 is moved without delay in the closing direction, with the result that the filling opening 13 already is completely closed before the press beam 17 takes effect. The sequence of movements described can be understood with reference to FIGS. 1 to 3. When the tobacco press chamber is opened, the sequence of movements takes place in exactly the opposite manner, ie the cover 1 hurries after the press beam 17.

Damit der Preßbalken 17 in Preßstellung verharrt, ist am unteren Ende jeder Steuernut 2 eine Erweiterung 15 vorgesehen, in die die Führungszapfen 6 einrasten. Die Erweiterung 15 und damit die erwähnte Rastverbindung liegen, wie Fig. 3a erkennen läßt, unterhalb der gedachten Verbindungslinie zwischen Tabakpreßkammer 14 und dem Schwenklager der Handhabe 23. Die Raststellung der Handhabe 23 ist also eine "Übertotpunkt-Stellung".So that the press beam 17 remains in the press position, an extension 15 is provided at the lower end of each control groove 2, into which the guide pins 6 engage. The extension 15 and thus the mentioned locking connection, as can be seen in FIG. 3a, below the imaginary connecting line between the tobacco pressing chamber 14 and the pivot bearing of the handle 23. The locking position of the handle 23 is therefore an "over-center position".

Entsprechend den Fig. 1 bis 3 wird also durch die Füllöffnung 13 zunächst Tabak in die Tabakpreßkammer 14 eingefüllt. Anschließend wird durch den voreilenden Deckel 1 die Füllöffnung 13 verschlossen, wobei die der Preßkammer 14 zugewandte Vorderkante 4 des Deckels preßkammerseitig abgeschrägt ist unter Ausbildung einer messarartigen Schneide 5. Dadurch wird der eingefüllte Tabak in die Tabakpreßkammer 14 beim Verschließen der Öffnung 13 durch den Deckel 1 regelrecht "hineingerollt". Gegebenenfalls noch überstehende Tabakreste werden zwischen der Schneide 5 und der dem Preßbalken 17 gegenüberliegenden Begrenzungskante 7 der Füllöffnung 13 abgetrennt, so daß sich der eingefüllte Tabak praktisch vollständig innerhalb der Tabakpreßkammer 14 befindet. Der letztlich hergestellte Tabakstrang 10 entsprechend Fig. 3 läßt sich dann problemlos aus der Tabakpreßkammer 14 ausstoßen. Wie Fig. 3 im übrigen noch erkennen läßt, ist in Tabakpreßstellung des Preßbalkens 17 die Vorderkante 4 des Deckels 1 mit der gewölbten Praßfläche 16 des Preßbalkens 17 etwa bündig unter entsprechender Fortsetzung der Preßfläche 16 des Preßbalkens 17.According to FIGS. 1 to 3, tobacco is first filled into the tobacco pressing chamber 14 through the filling opening 13. Subsequently, the filling opening 13 is closed by the leading cover 1, the front edge 4 of the cover facing the press chamber 14 being chamfered on the press chamber side to form a messar-like cutting edge 5. As a result, the filled tobacco is inserted into the tobacco press chamber 14 when the opening 13 is closed by the cover 1 literally "rolled in". Any remaining tobacco residues are cut off between the cutting edge 5 and the boundary edge 7 of the filling opening 13 opposite the press beam 17, so that the filled tobacco is practically completely inside the tobacco compression chamber 14. The tobacco rod 10 ultimately produced in accordance with FIG. 3 can then be easily ejected from the tobacco compression chamber 14. As can also be seen in FIG. 3, in the tobacco press position of the press beam 17, the front edge 4 of the cover 1 is approximately flush with the curved pressing surface 16 of the press beam 17 with a corresponding continuation of the press surface 16 of the press beam 17.

Anhand der Fig. 4 bis 6 sowie 9 bis 12 soll nun eine Ausführungsform beschrieben werden, bei der der Preßbalken 17 in eine Überkompressionsstellung bewegbar ist (Fig. 5), in welcher der freie Querschnitt der Preßkammer 14 merklich kleiner ist als der freie Querschnitt des Tabakaufnahmeraums der nicht dargestellten Zigarettenhülse, wobei unmittelbar vor dem oder wenigstens beim Ausstoßen des Tabakstrangs 10 (Fig. 6) aus der Preßkammer 14 eine Rückbewegung des Preßbalkens 17 etwa auf "Normalmaß" erfolgt, d. h. in eine Stellung, in der der freie Querschnitt der Tabakpreßkammer 14 etwa gleich dem, vorzugsweise nur noch geringfügig kleiner als der freie Querschnitt des Tabakaufnahmeraums der angesetzten Zigarettenhülse. Vorzugsweise wird der Tabak zunächst auf ein Querschnittsmaß komprimiert, welches um etwa 10 bis 20 % kleiner ist als das "Normalmaß", um dann vor dem oder beim Ausstoßen aus der Preßkammer 14 auf ein Maß entlastet zu werden, welches nur noch etwa 3 bis 6 % kleiner ist als das "Normalmaß", wobei die genannten Bewegungen des Preßbalken 17 durch eine, gegebenenfalls mit dem Ausstoßschieber gekoppelte, hier nicht näher dargestellte Steuerbahn (Steuernocke) gesteuert sind. Die zuletzt erwähnte Maßnahme kann mit der vorbeschriebenen Deckel-Konstruktion kombiniert werden. Sie ist jedoch auch unabhängig davon anwendbar. Herkömmliche Stopfgeräte Sind in entsprechender Weise modifizierbar, so daß auf den eingangs erwähnten Löffel am ausstoßseitigen Ende des Ausstoßschiebers verzichtet werden kann.4 to 6 and 9 to 12, an embodiment will now be described in which the pressure beam 17 can be moved into an over-compression position (FIG. 5), in which the free cross section of the press chamber 14 is significantly smaller than the free cross section of the Tobacco receiving space of the cigarette tube, not shown, wherein immediately before or at least when the tobacco rod 10 (FIG. 6) is ejected from the press chamber 14, the press beam 17 moves back to approximately "normal size", ie into a position in which the free cross section of the tobacco press chamber 14 about the same, preferably only slightly smaller than the free cross-section of the tobacco-receiving space of the attached cigarette tube. Preferably, the tobacco is first compressed to a cross-sectional dimension which is approximately 10 to 20% smaller than the "normal dimension", in order to be relieved before or during ejection from the press chamber 14 to a dimension which is only about 3 to 6 % is smaller than the "normal size", the movements of the press beam 17 being controlled by a control path (control cam), which is optionally coupled to the ejection slide and is not shown here. The last-mentioned measure can be combined with the lid construction described above. However, it can also be used independently. Conventional tamping devices can be modified in a corresponding manner, so that the bucket mentioned at the beginning of the discharge end of the discharge slide can be dispensed with.

Bei der Ausführungsform nach den Fig. 9 bis 12 erfolgt die Vor- und Überkomprimierung des Tabaks in äußerst einfacher Weise, und zwar durch eine dem Preßbalken zugeordnete Kompressionsleiste 27, die bei der dargestellten Ausführungsform den Preßbalken 17 im wesentlichen über die gesamte Länge der Tabak-Preßkammer 14 durchsetzt, wobei die Kompressionsleiste 27 an der der Tabak-Preßkammer 14 abgewandten Seite durch Federelemente, hier Schraubendruckfedern 28 elastisch nachgiebig abgestützt ist. Um sicherzustellen, daß vor dem Ausstoßen des Tabakstrangs aus der Tabakpreßkammer 14 die Kompressionsleiste 14 nicht mehr in die Tabakpreßkammer 14 hineinragt, sind an den beiden diametralen Enden der Kompressionsleiste 27 nicht näher dargestellte Anschläge vorgesehen, die in Preßstellung des Preßbalkens 17 eine Bewegung der Kompressionsleiste 27 aus der Preßkammer 14 heraus bewirken, vorzugsweise derart, daß die der Tabakpreßkammer 14 zugewandte Seite der Kompressionsleiste 27 mit der Preßfläche 16 des Preßbalkens 17 bündig ist. Auf diese Weise wird die Axialbewegung des Ausstoßschiebers beim Überführen des verpreßten Tabakstrangs in eine angesetzte Zigarettenhülse durch die Kompressionsleiste 27 nicht behindert. In den Fig. 10 bis 12 ragt die Kompressionsleiste 27 zur besseren Veranschaulichung in die Tabakpreßkammer 14 hinein. In der dargestellten Stellung des Stopfgerätes müßte die Kompressionsleiste 27 jedoch durch die erwähnten Anschläge entgegen der Wirkung der Druckfedern 28 aus der Tabakpreßkammer herausbewegt sein, derart, daß die der Tabakpreßkammer 14 zugewandte Seite der Kompressionsleiste 27 mit dar Preßfläche 16 des Preßbalkens 17 bündig ist. Die erwähnten und in den Fig. nicht näher dargestellten Anschläge sind vorzugsweise auch derart wirksam, daß die Kompressionsleiste 27 erst kurz vor Erreichen der endgültigen Preßstellung das Preßbalkens 17 aus der Preßkammer 14 herausbewegt wird.In the embodiment according to FIGS. 9 to 12, the pre-and over-compression of the tobacco takes place in an extremely simple manner, namely by means of a compression bar 27 which is assigned to the pressure bar and which, in the embodiment shown, the pressure bar 17 essentially over the entire length of the tobacco Press chamber 14 passes through, the compression strip 27 being elastically resiliently supported on the side facing away from the tobacco press chamber 14 by spring elements, here helical compression springs 28. To ensure that before the tobacco rod is ejected from the tobacco press chamber 14, the compression bar 14 no longer projects into the tobacco press chamber 14, stops (not shown in more detail) are provided on the two diametrical ends of the compression bar 27, which move the compression bar 27 in the pressing position of the pressure bar 17 cause out of the press chamber 14, preferably such that the side of the compression bar 27 facing the tobacco press chamber 14 is flush with the press surface 16 of the press beam 17. In this way, the axial movement of the ejector slide when the compressed tobacco rod is transferred into an attached cigarette tube not hindered by the compression bar 27. 10 to 12, the compression bar 27 projects into the tobacco pressing chamber 14 for better illustration. In the illustrated position of the tamping device, however, the compression bar 27 would have to be moved out of the tobacco press chamber by the abovementioned stops against the action of the compression springs 28, such that the side of the compression bar 27 facing the tobacco press chamber 14 is flush with the press surface 16 of the press beam 17. The stops mentioned and not shown in the figures are preferably also effective in such a way that the compression bar 27 only moves the press bar 17 out of the press chamber 14 shortly before the final pressing position is reached.

Zum besseren Verständnis des Stopfgerätes nach den Fig. 9 bis 11 wird dieses im folgenden etwas näher erläutert: Anhand der Fig. 9 ergibt sich, daß bei dem dargestellten Stopfgerät mit einem Bodenteil 29 über eine daran angeordnete Scharnierachse 8 schwenkbar ein Gehäuse 9 und ein Deckel 30 verbunden sind. Seitlich am Gehäuse ist ein mit dem Ausstoßschieber verbundenes Batätigungselement 31 parallel zum Bodenteil 29 verschiebbar gelagert.For a better understanding of the tamping device according to FIGS. 9 to 11, this is explained in more detail below: With reference to FIG. 9, it follows that in the shown tamping device with a base part 29, a housing 9 and a cover can be pivoted via a hinge axis 8 arranged thereon 30 are connected. On the side of the housing, a actuating element 31 connected to the ejection slide is slidably mounted parallel to the bottom part 29.

Fig. 10 zeigt einen Längsschnitt durch das Gerät gemäß Fig. 9. Der Bodenteil 29 ist etwa wannenförmig ausgebildet und trägt an seinem hinteren Ende eine Scharnier-Achsenausbildung 8, um die einerseits, wie erwähnt ein Gehäuse 9 und ein Deckel 30 schwenkbar gelagert sind. Das Gehäuse 9 weist an seiner oberen Deckfläche eine muldenartige Einfüllöffnung 13 auf, durch die der Tabak in eine Tabakpreßkammer 14 einfüllbar ist. Der Deckel 30 ist an seiner Unterseite mit einem Preßbalken 17 versehen, mit dem der eingefüllte Tabak so weit zusammengepreßt wird, daß er einen in eine an einer Tülle 32 aufsteckbare Zigarettenhülse einschiebbaren Tabakstrang bildet. Der Ausstoßschieber ist - wie bei den vorherigen Ausführungsformen - mit der Bezugsziffer 25 gekennzeichnet. Im Bodenteil 29 ist ein Klemmelement 33 vorgesehen, welches während des Stopfvorganges die nicht näher dargestellte Zigarettenhülse an der Tülle 32 andrückt. Der Deckel 30 weist seitlich Nasen 34 auf, die in Nuten 35 des Gehäuses eingreifen und durch diese, während des Stopfvorganges, derart geführt werden, daß der Deckel 30 gegenüber dem Ausstoßschieber bzw. dessen Betätigungselement 31 und gleichzeitig gegenüber dem Gehäuse 9 verriegelt wird. Die rückwärtige Begrenzung der Tabakpreßkammer 14 wird durch den Ausstoßschieber 25 gebildet.FIG. 10 shows a longitudinal section through the device according to FIG. 9. The base part 29 is approximately trough-shaped and carries at its rear end a hinge axis configuration 8, around which, as mentioned, a housing 9 and a cover 30 are pivotably mounted. The housing 9 has on its upper cover surface a trough-like filling opening 13 through which the tobacco can be filled into a tobacco compression chamber 14. The lid 30 is provided on its underside with a press bar 17, with which the filled tobacco is pressed together to such an extent that it forms a tobacco rod which can be inserted into a cigarette tube which can be plugged onto a spout 32. As in the previous embodiments, the discharge slide is identified by the reference number 25. In the bottom part 29 is a clamping element 33 is provided which presses the cigarette tube (not shown in detail) against the spout 32 during the tamping process. The cover 30 laterally has lugs 34 which engage in grooves 35 of the housing and are guided through them during the tamping process in such a way that the cover 30 is locked with respect to the ejection slide or its actuating element 31 and at the same time with respect to the housing 9. The rear boundary of the tobacco compression chamber 14 is formed by the ejection slide 25.

Die Fig. 11 und 12 zeigen eine Stirnansicht, wobei die Fig. 11 die Stirnansicht des Stopfgerätes im geschlossenen Zustand vor dem Stopfvorgang zeigt, während Fig. 12 einen Schnitt durch das Gerät hinter der Stirnwand des Gehäuses 9 darstellt.11 and 12 show an end view, FIG. 11 showing the end view of the tamping device in the closed state before the tamping process, while FIG. 12 shows a section through the device behind the end wall of the housing 9.

Aus den Fig. 10 bis 12 ist ersichtlich, daß das Stopfgerät im wesentlichen aus vier Teilen besteht, nämlich dem Bodenteil 29, dem Gehäuse 9, dem Deckel 30 und dem Ausstoßschieber 25 zugeordneten Betätigungselement 31. Der Deckel 30 untergreift mit einer Nase 34 eine Nut 35 im Betätigungselement 31 des Ausstoßschiebers 25, während das Betätigungselement 31 mit einer Führungsleiste 36 einen Führungswinkel 37 des Bodenteils 29 untergreift. Mit einer Führungsleiste 38 ist das mit dem Ausstoßschieber 25 verbundene Betätigungselement 31 in einer Nut 47 im Gehäuse 9 geführt. Am Bodenteil 29 ist ferner mindestens eine Feder 48 vorgesehen, die von unten gegen das Gehäuse 9 drückt und dieses im Ruhezustand vom Bodenteil 29 wegdrückt. Dadurch ist im Ruhezustand auch ein Abstand zwischen dem Klemmelement 33 und der Tülle 32 sichergestellt.10 to 12 it can be seen that the tamping device consists essentially of four parts, namely the bottom part 29, the housing 9, the cover 30 and the ejection slide 25 associated actuating element 31. The cover 30 engages under a groove with a nose 34 35 in the actuating element 31 of the ejection slide 25, while the actuating element 31 engages under a guide angle 37 of the base part 29 with a guide bar 36. The actuating element 31 connected to the ejection slide 25 is guided in a groove 47 in the housing 9 with a guide bar 38. At least one spring 48 is also provided on the bottom part 29, which presses against the housing 9 from below and pushes it away from the bottom part 29 in the idle state. This also ensures a distance between the clamping element 33 and the spout 32 in the idle state.

Da es sich bei der dargestellten Grundkonstruktion des Stopfgerätes um ein herkömmliches Stopfgerät handelt, genügt die obige Aufzählung der einzelnen Konstruktionsmerkmale. Eine Funktionsbeschreibung erscheint entbehrlich.Since the basic construction of the tamping device shown is a conventional tamping device, the above list of the individual design features suffices. A functional description appears to be unnecessary.

Die Fig. 7 und 8 zeigen eine weitere Ausführungsform eines Stopfgerätes ähnlich derjenigen nach den Fig. 9 bis 12, wobei der Kern dieser Ausführungsform in der diametralen Anordung von Klemmelementen 49 und deren Betätigung liegt. Das dargestellte Stopfgerät weist eine Vorderwand 50 auf, in der sich eine Austrittsöffnung 51 für den innerhalb der nicht näher dargestellten Tabakpreßkammer ausgebildeten Tabakstrang befindet und an welcher eine Tülle 52 mit einer aufsteckbaren Zigarettenhülse 53 (Fig. 8) angeordnet ist. Das Gerät wird durch einen Boden 54 und durch einen Deckelteil 55 abgeschlossen. Ein mit dem nicht dargestellten Ausstoßschieber verbundenes Betätigungselement 56 wird an parallellaufenden, nach innen gerichteten seitlichen Leisten 57, 58 am verschwenkbaren, im übrigen jedoch systemfest angeordneten Füllteil entlang geführt. An der vorderen Wand 50 ist beispielsweise mittels Niete 59, 60 oder dergleichen ein Halteteil 61 mit einem Halteblock 62 zur Aufnahme und zur Führung eines Klemmelements 49 vorgesehen. Das der Tülle 52 zugeordnete Ende 63 der relativ zur Tülle 52 diametral angeordneten Klemmelemente 49 ist jeweils konkav ausgebildet. Die jeweils anderen Enden 64 stehen in Gleitkontakt mit den Leisten 57, 58 des Betätigungselements 56. Die Klemmelemente 49 stehen jeweils unter Wirkung eines elastischen Bauteils, insbesondere elastischen Druckelements, z. B. einer Druckfeder 65, die im Ruhezustand die Klemmelemente 49 von der Tülle 52 wegdrücken. Die vorzugsweise horizontal geführten Klemmelemente 49 befinden sich somit bei entspannter Feder 65 auch im Ruhezustand, sobald vor oder nach Betätigung des mit dem Ausstoßschieber gekoppelten Betätigungselements 56 die Halteblöcke 62 sich jeweils in einem der Endbereiche der Leisten 57, 58 befinden, wobei die Klemmelemente 49 gemäß Fig. 8 die ersichtliche, strich-punktierte Lage einnehmen. Damit ist gleichzeitig der für das Aufstecken oder für die Abnahme der Zigarettenhülse 4 auf die oder von der Tülle 52 erforderliche Abstand zwischen den konkaven Enden 63 der Klemmelemente 49 und der Außenwandung der Tülle 52 hergestellt. Wird das Betätigungselement 56 mit dem vorbereiteten Tabakstrang axial verschoben unter entsprechender Mitnahme des nicht dargestellten Ausstoßschiebers, werden die Klemmelemente 49 durch zunehmende Dicke dar Leisten 57, 58 gegen den Druck der Federn 65 in Richtung auf die Tülle 52 gedrückt. Dementsprechend wird für die Dauer des Stopfvorganges die Zigarettenhülse 53 gegen die Außenwandung dar Tülle 52 geklemmt. Auf diese Weise ist für einen ordnungsgemäßen Stopfvorgang der Zigarettenhülse gesorgt. Selbstverständlich ist es insbesondere bei Stopfgeräten anderer Ausführungsform denkbar, drei oder mehr jeweils gleichmäßig über den Umfang der Tülle 52 angeordnete Klemmelemente 49 anzuordnen, um einen sicheren Halt der auf die Tülle 52 aufgesteckten Zigarettenhülse während dar Tabaküberführung bzw. des Stopfvorgangs zu gewährleisten. Das Prinzip der Mehrfachklemmung der Zigarettenhülse auf der Tülle ist auch für herkömmliche Stopfgeräte von größter Bedeutung, aber auch in Kombination mit den vorbeschriebenen Stopfgeräten bzw. -Vorrichtungen.7 and 8 show a further embodiment of a tamping device similar to that according to FIGS. 9 to 12, the core of this embodiment being the diametrical arrangement of clamping elements 49 and their actuation. The tamping device shown has a front wall 50 in which there is an outlet opening 51 for the tobacco rod formed within the tobacco press chamber (not shown in more detail) and on which a spout 52 with an attachable cigarette tube 53 (FIG. 8) is arranged. The device is closed by a bottom 54 and by a cover part 55. An actuating element 56 connected to the ejection slide, not shown, is guided along parallel, inwardly directed lateral strips 57, 58 along the pivotable, but otherwise system-fixed, filling part. A holding part 61 with a holding block 62 for receiving and guiding a clamping element 49 is provided on the front wall 50, for example by means of rivets 59, 60 or the like. The end 63 assigned to the spout 52 of the clamping elements 49 arranged diametrically relative to the spout 52 is concave in each case. The respective other ends 64 are in sliding contact with the strips 57, 58 of the actuating element 56. The clamping elements 49 are each under the action of an elastic component, in particular an elastic pressure element, for. B. a compression spring 65, which push the clamping elements 49 away from the spout 52 in the idle state. The preferably horizontally guided clamping elements 49 are thus also in the idle state when the spring 65 is relaxed, as soon as the holding blocks 62 are located in one of the end regions of the strips 57, 58 before or after actuating the actuating element 56 coupled to the ejection slide, the clamping elements 49 according to Fig. 8 take the apparent, dash-dotted position. At the same time, the distance between the concave ends 63 of the clamping elements 49 and the outer wall of the spout 52, which is required for attaching or removing the cigarette tube 4 to or from the spout 52, is produced. The actuating element 56 with the prepared tobacco rod is axially shifted under Corresponding entrainment of the ejection slide, not shown, the clamping elements 49 are pressed by increasing the thickness of the strips 57, 58 against the pressure of the springs 65 in the direction of the spout 52. Accordingly, the cigarette tube 53 is clamped against the outer wall of the spout 52 for the duration of the tamping process. This ensures that the cigarette tube is properly stuffed. Of course, it is conceivable, in particular in the case of tamping devices of another embodiment, to arrange three or more clamping elements 49 which are each arranged uniformly over the circumference of the spout 52, in order to ensure a secure hold of the cigarette tube fitted onto the spout 52 during the transfer of tobacco or the tamping process. The principle of multiple clamping of the cigarette tube on the spout is also of great importance for conventional tamping devices, but also in combination with the previously described tamping devices or devices.
