Description

Die Erfindung betrifft ein Gerät zum automatischen Stopfen von Zigarettentabak in vorgefertigte Zigarettenhülsen, vorzugsweise Filter-Zigarettenhülsen und kontinuierlichem Erstellen einer Anzahl von rauchfertig gestopften Zigaretten, mit einem Tabak-Einfülltrichter und unterhalb dieses Trichters vorgesehenem Tabak- Vorratsraum, wobei am Grunde des Tabak- Vorratsraumes ein querbeweglicher, mit einer Hohlkehle versehener Preßbalken angeordnet ist, der unter Formung eines Tabakstranges gegen ein ebenfalls mit einer Hohlkehle versehenes formstück bewegbar ist, wobei ein in der Hohlkehle des Formstückes längsbeweglich verschiebbares Ausstoßelement vorgesehen und in der Verlängerung der Hohlkehle (Preßraum) ein Zigarettenhülsen-Aufnahmestutzen ausgebildet ist, auf den die zu füllende Zigarettenhülse aufschiebbar ist, und wobei der geformte Tabakstrang mittels des Ausstoßelementes in die Zigarettenhülse eingeschoben wird.The invention relates to a device for the automatic stuffing of cigarette tobacco into prefabricated cigarette tubes, preferably filter cigarette tubes and continuous production of a number of ready-to-smoke cigarettes, with a tobacco filling funnel and a tobacco storage space provided underneath this funnel, with a tobacco storage space at the base is arranged transversely movable, provided with a fillet, which can be moved to form a tobacco rod against a shaped piece also provided with a fillet, with an ejector element which is longitudinally displaceable in the fillet of the shaped piece and in the extension of the fillet (press space) a cigarette tube receptacle is formed, on which the cigarette tube to be filled can be pushed, and wherein the shaped tobacco rod is inserted into the cigarette tube by means of the ejection element.

Es sind manuell zu betätigende Zigarettenstopfgeräte bekannt z. B. aus der DE-C-1 295 448, bei denen eine etwa für eine Zigarettenfüllung erforderliche Tabakmenge in eine längliche, schalenförmige Formvorrichtung eingefüllt wird. Anschließend wird eine Andruckschale auf den vorgeformten Tabakstrang gepreßt und der Tabak zu einem runden Tabakstrang geformt.Manually operated cigarette stuffers are known for. B. from DE-C-1 295 448, in which an amount of tobacco required for a cigarette is filled in an elongated, bowl-shaped molding device. A pressure bowl is then pressed onto the preformed tobacco rod and the tobacco is shaped into a round tobacco rod.

Mittels einer manuell zu betätigenden Hebeleinrichtung wird der geformte Tabakstrang anschließend in eine zuvor auf eine Halterungstülle aufgesteckte und ggfls. durch ein Andruckglied festgehaltene Zigarettenhülse gedrückt.By means of a manually operated lever device, the shaped tobacco rod is then placed in a holder previously on a holder and if necessary. pressed by a pressure member cigarette tube.

Diese bekannten Geräte sind jedoch legiglich zur Erstellung einzelner Zigaretten ausgebildet.However, these known devices are only designed to create individual cigarettes.

Hierbei ist es nötig, für jede einzelne Zigarettenfüllung die entsprechende Tabakmenge in etwa vorportioniert in das Gerät einzufüllen. Die hiermit verbundenen Manipulationen und Arbeiten, wie z. B. mittels Hand zu entnehmende einzelne Tabakmengen aus einer Vorratsdose, Einfüllen in das Gerät, Aufziehen einer Leerhülse auf einen Füllstutzen des Gerätes, Betätigen des Gerätes usw. sind derart aufwendig, daß die Herstellung einer größeren Anzahl gestopfter Zigaretten, beispielsweise des Tagesbedarfs eines Rauchers oder gar einer Raucher-Familie oftmals nicht lohnend erscheint und derartige Geräte vom Anwender nach anfänglich häufiger Benutzung (kurz nach dem Erwerb) späterhin nur noch gelegentlich oder auch gar nicht mehr benutzt werden.It is necessary to fill the corresponding amount of tobacco into the device in approximately pre-portioned form for each individual cigarette filling. The associated manipulations and work such. B. to be removed by hand individual quantities of tobacco from a storage container, filling in the device, opening an empty tube on a filler neck of the device, operating the device, etc. are so complex that the production of a larger number of stuffed cigarettes, such as the daily needs of a smoker or even a smoking family often does not seem worthwhile and such devices are only used occasionally or not at all by the user after initially frequent use (shortly after purchase).

Darüber hinaus ist aus der FR-A-378 470 ein Gerät zum automatischen Stopfen von Zigarettentabak in vorgefertigte Zigarettenhülsen bekannt, das mit einem Einfülltrichter/Tabak-Vorratsbehälter versehen ist und bei dem in einer Tabakstrang-Formstation mittels eines mit einer Hohlkehle versehenen Preßbalkens, der mit einem entsprechenden Formstück zusammenwirkt, ein runder Tabakstrang geformt wird. Es ist weiterhin ein Aufnahmestutzen für eine Zigaretten-Leerhülse vorgesehen, wobei der geformte Tabakstrang mittels eines Ausstoßelementes in die Leerhülse eingeschoben wird. Während des Füllvorganges wird die Leerhülse durch besondere Andruckmittel auf dem Aufnahmestutzen festgeklemmt.In addition, from FR-A-378 470 a device for automatically stuffing cigarette tobacco into prefabricated cigarette tubes is known, which is provided with a hopper / tobacco storage container and in which in a tobacco rod forming station by means of a press beam provided with a groove, the interacts with a corresponding fitting, a round tobacco rod is formed. A receptacle for an empty cigarette tube is also provided, the shaped tobacco rod being pushed into the empty tube by means of an ejection element. During the filling process, the empty sleeve is clamped onto the receptacle by special pressure means.

Nach dem Füllen der Zigarettenhülse wird diese vom Aufnahmestutzen entfernt und kann dem Gerät entnommen werden. Bei dem bekannten Gerät ist weiterhin ein Vorratsbehälter für Zigaretten-Leerhülsen vorgesehen, aus dem heraus mittels eines Schiebers jeweils eine Leerhülse ausgeschoben und dem Aufnahmestutzen zugeleitet wird. Das bekannte Gerät arbeitet im großen und ganzen zufriedenstellend, wobei jedoch im Hinblick auf das Zu- und Abführen der Zigarettenhülsen häufig Probleme auftauchen, die zu Betriebsstörungen führen, so daß das Gerät nicht unbeaufsichtigt betrieben werden kann. Hierbei kommt es häufig zu nicht einwandfrei bzw. gar nicht auf den Stutzen aufgeschobenen Leerhülsen, da die Leerhülsen, die ja aus sehr dünnem Papier bestehen, äußerst diffizile und leicht verformbare Gebilde sind, wobei schon geringste Behinderungen ausreichen, um die Hülsen zu deformieren und letztendlich zu zerquetschen.After filling the cigarette tube, it is removed from the socket and can be removed from the device. In the known device, a storage container for empty cigarette tubes is also provided, from which an empty tube is pushed out by means of a slide and fed to the receptacle. The known device works satisfactorily on the whole, but problems often arise with regard to the feeding and removal of the cigarette tubes, which lead to malfunctions, so that the device cannot be operated unattended. This often results in empty sleeves not being pushed properly or not at all onto the connecting piece, since the empty sleeves, which are made of very thin paper, are extremely difficult and easily deformable structures, with even the slightest disability being sufficient to deform the sleeves and ultimately to crush.

Der Erfindung liegt nunmehr die Aufgabe zugrunde, ein Gerät zum Stopfen von Zigaretten so auszubilden, daß es zur kontinuierlichen, störungsfreien Herstellung einer größeren Anzahl von gestopfen Zigaretten geeignet ist, wobei insbesondere die Zu- und Abführung von Zigarettenhülsen so gestaltet werden soll, daß Beschädigungen/Deformationen der Zigarettenhülsen bei der Verarbeitung im Gerät weitestgehend ausgeschlossen sind.The invention is based on the object of designing a device for stuffing cigarettes in such a way that it is suitable for the continuous, trouble-free manufacture of a large number of stuffed cigarettes, in particular the supply and removal of cigarette tubes should be designed so that damage / Deformations of the cigarette tubes during processing in the device are largely excluded.

Die Herstellung der Zigaretten soll dabei selbsttätig aus einem Tabakvorrat erfolgen, wobei außer dem Einbringen einer größeren Tabakmenge, dem Einfüllen eines Leerhülsenvorrates und dem anschließenden Entnehmen von fertig gestopften Zigaretten keine weiteren Handlungen des Benutzers erforderlich sind.The manufacture of the cigarettes is to take place automatically from a tobacco supply, with no further action by the user being required in addition to the introduction of a larger quantity of tobacco, the filling of an empty tube supply and the subsequent removal of fully packaged cigarettes.

Diese Aufgabe wird erfindungsgemäß durch die im kennzeichnenden Teil des Anspruches 1 angegebenen Merkmale gelöst.This object is achieved by the features specified in the characterizing part of claim 1.

Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den Ansprüchen 2 bis 22 näher erläutert.Further advantageous embodiments of the invention are explained in more detail in claims 2 to 22.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß ein völlig selbständig arbeitendes Gerät geschaffen wurde, das die problemlose Herstellung einer größeren Anzahl von rauchfertigen Zigaretten ermöglicht. Dabei ist ein weiterer Vorteil darin zu sehen, daß die Stopffestigkeit der Zigaretten unter Berücksichtigung von der Tabakstruktur, Feuchte etc. individuell einstellbar ist.The advantages achieved by the invention consist in particular in the fact that a completely independent device has been created which enables the problem-free production of a larger number of smoke-ready cigarettes. Another advantage is the fact that the cigarette's resistance to cigarette packing can be individually adjusted taking into account the tobacco structure, moisture, etc.

In der Fig. 1 ist das erfindungsgemäße Gerät zum automatischen Stopfen von Zigarettentabak in Zugarettenhülsen in seiner Gesamtheit dargestellt, wobei zwecks besserer Übersicht das äußere Gehäuse nicht gezeichnet ist.In Fig. 1, the device according to the invention for the automatic stuffing of cigarette tobacco in Zugarettenhülsen is shown in its entirety, the outer housing is not shown for a better overview.

Es ist eine Basisplatte 1 vorgesehen, auf der Tragwände 2,3,4,5, 6 angebracht sind, die der Halterung der verschiedenen Bauteile des Gerätes dienen. Elektro-Motore 7, 8 sind für den Antrieb der aktiven (beweglichen) Teile des Gerätes vorgesehen. Eine elektrische/elektronische Steuerung 9, die die ablaufgerechte Steuerung der Motore und somit des Betriebsablaufes des Gerätes bewirkt, ist als steckbarer Baustein vorgesehen. Im mittleren Teil des Gerätes ist ein Tabak-Einfülltrichter 10 angeordnet. Auf der linken Seite des Gerätes befindet sich ein schräg verlaufender Zigaretten-Leerhülsen-Vorratsbehälter 11. Die Schräganordnung dieses Behälters ist - vorgesehen, damit die Leerhülsen beim Betrieb des Gerätes immer in die vordere Entnahmeposition nachrutschen. Der Behälter ist vorzugsweise mit einem aufrastbaren KlarsichtDeckel versehen, um die Füllung visuell kontrollieren zu können. Es ist vorgesehen, daß der Behälter bei Nichtgebrauch des Gerätes in dieses, in eine waagerechte Lage verschwenkt werden kann.A base plate 1 is provided, on which supporting walls 2, 3, 4, 5, 6 are attached, which serve to hold the various components of the device. Electric motors 7, 8 are provided for driving the active (movable) parts of the device. An electrical / electronic control 9, which effects the proper control of the motors and thus the operating sequence of the device, is provided as a pluggable component. A tobacco hopper 10 is arranged in the middle part of the device. On the left side of the device there is an oblique cigarette empty-case storage container 11. The inclined arrangement of this container is provided so that the empty cases always slide into the front removal position when the device is in operation. The container is preferably provided with a snap-on transparent cover in order to be able to visually check the filling. It is envisaged that the container can be pivoted into a horizontal position when the device is not in use.

Zur detaillierten Beschreibung des Geräteaufbaues und der Funktionsabläufe wird nunmehr auf die Fig. 2 bis 11 Bezug genommen. Dabei sind in diesen Abbildungen jeweils nur Teilbereiche unter Fortlassung anderer Teile dargestellt, um die funktionswesentlichen Teile besser darstellen und erläutern zu können.For a detailed description of the device structure and the functional sequences, reference is now made to FIGS. 2 to 11. Only partial areas are shown in these figures, leaving out other parts in order to better illustrate and explain the functionally important parts.

In der Trichtermündung des Tabak-Einfülltrichters 10 ist eine Tabak-Zerteil-Einrichtung (Fig. 4) vorgesehen, die im wesentlichen aus zwei beabstandeten, gegenläufig drehbaren Dosierwellen 13, 14 und einem in dem Durchlaßspalt 15 fest angeordneten kammförmigen Rechen 16 besteht. Die Dosierwellen sind mit spiralförmig eingeformten Ausnehmungen 17, ähnlich einem Spiralbohrer, versehen und weisen Schneidkanten 18 auf, wobei grobere Tabakfasern beim Fördern durch den Durchlaßspalt in Verbindung mit dem Rechen 16 durchtrennt werden. Über dem Rechen ist ein schwenkbarer Bügel 19 vorgesehen, der zur Auflockerung des eingefüllten Tabaks dient. Zur Auflockerung des Tabaks kann auch vorgesehen sein, daß die untere Seite des Bügels kammförmig ausgebildet ist oder daß oberhalb der Dosierwellen 13, 14 und des Rechens 16 im Einfülltrichter eine durchgehende Achse 19' mit um einen Winkel versetzt angeordneten blattförmigen (messerartigen) Laschen 82 vorgesehen ist, die bis dicht über die Dosiereinrichtung reichen und die beim Betrieb der Dosierwellen über diesen hin und her geschwenkt werden.In the funnel mouth of the tobacco filling funnel 10, a tobacco cutting device (FIG. 4) is provided, which essentially consists of two spaced, counter-rotating metering shafts 13, 14 and a comb-shaped rake 16 fixedly arranged in the passage gap 15. The metering shafts are provided with spirally formed recesses 17, similar to a twist drill, and have cutting edges 18, with coarser tobacco fibers being cut through the passage gap in connection with the rake 16. A swiveling bracket 19 is provided above the rake, which serves to loosen the tobacco that has been filled in. To loosen the tobacco, it can also be provided that the lower side of the bracket is comb-shaped or that above the metering shafts 13, 14 and the rake 16 in the filling funnel a continuous axis 19 'with sheet-shaped (knife-like) tabs 82 arranged offset by an angle is provided is, which extend to close to the metering device and which are pivoted back and forth during operation of the metering shafts.

Der Antrieb der Dosierwellen erfolgt über ein Rädergetriebe 20 durch den Motor 7. Da die Drehung der Dosierwellen nicht dauernd erfolgen darf, sondern innerhalb eines Arbeitsspieles des Gerätes nur zeitweilig, da sonst zuviel Tabak in den Tabak-Vorratsraum 25 gefördert wird, ist deren Antrieb über ein Schaltrad 21 zu- und abschaltbar, wobei das Schaltrad mittels eines Elektromagneten 22 betätigt wird. Selbstverständlich kann hier auch ein separater Antriebsmotor vorgesehen sein, der entsprechend der benötigten Dosierwellendrehung ein- und ausgeschaltet wird.The metering shafts are driven via a gear mechanism 20 by the motor 7. Since the metering shafts must not be rotated continuously, but only intermittently within one working cycle of the device, since otherwise too much tobacco is conveyed into the tobacco storage room 25, their drive is over a ratchet wheel 21 can be switched on and off, the ratchet wheel being actuated by means of an electromagnet 22. Of course, a separate drive motor can also be provided here, which is switched on and off in accordance with the required metering shaft rotation.

Durch die Zeitdauer der Dosierwellendrehung kann gleichzeitig die Menge des zu einem Strang geformten Tabaks und damit die Stopffestigkeit der fertigen Zigarette beeinflußt werden. Dabei wird dann abhängig von der Dauer der Dosierwellendrehung mehr oder weniger Tabak bei zurückgezogenem Preßbalken 28 in den davor gebildeten Freiraum (Preßschacht) eingebracht.The amount of tobacco formed into a strand and thus the resistance to stuffing of the finished cigarette can be influenced at the same time by the duration of the metering shaft rotation. Depending on the duration of the metering shaft rotation, more or less tobacco is then introduced into the free space (press shaft) previously formed with the press beam 28 withdrawn.

Vorzugsweise ist vorgesehen, daß die Dosierwellendrehung durch ein einstellbares Zeitglied einstellbar ist, wobei die Einstellung manuell an der Außenseite (Bedienseite) des Gerätes vorgenommen werden kann.It is preferably provided that the metering shaft rotation can be set by means of an adjustable timer, the setting being able to be carried out manually on the outside (operating side) of the device.

Die Bewegung (Hin- und Herschwenken) des Bügels 19 erfolgt durch ein mit einer der Dosierwellen 14 verbundenes Exzenterrad 23 und den mit der Bügelachse 19' verbundenen Exzenterhebel 24 (sh. Fig. 5)The movement (back and forth) of the bracket 19 is carried out by an eccentric wheel 23 connected to one of the metering shafts 14 and the eccentric lever 24 connected to the bracket axis 19 '(see FIG. 5).

Unterhalb des Tabak-Einfülltrichters 10 ist ein Tabak-Vorratsraum 25 vorgesehen, der seitlich durch die Tragwände 4, 5 sowie die Seitenteile 26, 27 begrenzt ist. Der Tabak-Vorratsraum endet nach unten hin auf dem querbeweglichen Preßbalken 28.A tobacco storage space 25 is provided below the tobacco hopper 10 and is laterally delimited by the supporting walls 4, 5 and the side parts 26, 27. The tobacco storage room ends at the bottom on the cross-movable press beam 28.

Die Breite des Vorratsraumes entspricht in etwa der Breite des Preßbalkens, dessen Breite wiederum der Länge des zu formenden Tabakstranges (Zigaretten-Stopflänge) entspricht. Wie in der Fig. 4 durch den Pfeil A gekennzeichnet, ist der Preßbalken vor- und zurückbeweglich. Die Bewegung des Preßbalkens erfolgt über ein Rädergetriebe 29 vom Motor 7. Dabei wird ein Haupt-Antriebsrad 30, das mit einem exzentrischen Zapfen 31 versehen ist, in Drehung versetzt. Dieser Zapfen greift in einen Querschlitz 32 im Preßbalken 28 ein und bewirkt somit dessen Vor- und Zurückbewegung. Vorzugsweise ist im Querschlitz des Preßbalkens ein federnd 33 gehaltenes Gleitstück 34 vorgesehen, um übermäßige Belastungen des Preßbalkens/Antriebes beim Preßvorgang aufzufangen. Solche Belastungen können ggfs. auftreten, wenn der zu pressende Tabak grobe Verunreinigungen enthält, die eine Bewegung des Preßbalkens bis in seine Preß-Endstellung verhindern.The width of the storage space corresponds approximately to the width of the press beam, the width of which again corresponds to the length of the tobacco rod to be shaped (cigarette stopper length). As indicated by the arrow A in FIG. 4, the press beam can be moved back and forth. The movement of the press beam takes place via a gear mechanism 29 from the motor 7. A main drive wheel 30, which is provided with an eccentric pin 31, is set in rotation. This pin engages in a transverse slot 32 in the press beam 28 and thus causes its back and forth movement. Preferably, a resilient 33 held slider 34 is provided in the transverse slot of the press beam in order to absorb excessive loads on the press beam / drive during the pressing process. Such loads can occur if the tobacco to be pressed contains coarse impurities which prevent the press beam from moving into its final press position.

Der Preßbalken ist an seiner Vorderseite mit einer Hohlkehle 35 versenen. In der in der Fig. 4 gezeigten Endstellung des Preßbalkens taucht dieser in einen Schlitz 36 des Formstückes 37 (Gegenlager) ein, wobei der Grund dieses .Schlitzes ebenfalls in der Form einer Hohlkehle 38 (halbrund) ausgebildet ist.The pressure beam is recessed at its front with a groove 35. In the end position of the press beam shown in FIG. 4, this plunges into a slot 36 of the shaped piece 37 (counter bearing), the base of this slot also being in the form of a groove 38 (semicircular).

Bei der Rückwärtsbewegung des Preßbalkens 28 wird vor dem Schlitz 36 des Formstückes 37 '1Iin Freiraum (Preßschacht) geschaffen, in den der Tabak aus dem Vorratsraum 25 hineinfällt. Bei der anschließenden Vorwärtsbewegung des Preßbalkens wird dieser in dem Freiraum hineingelangte Tabak zusammengeschoben und in den Schlitz des Formstückes hineingepreßt. Damit die im Freiraum befindlichen Tabakfasern nicht nach oben hin aus diesem während des -Preßbalken-Vorschubes herausquellen, ist ein Druckbügel 39 vorgesehen, der während dieses Vorschubes auf den Tabak gedrückt wird. Die ablaufgerechte Bewegung dieses Druckbügels erfolgt durch ein Koppelgestänge 40 (sh.Fig. 5), das mit einem, mit dem Preßbalken 28 verbundenen Winkelstück 41 in Wirkverbindung steht.During the backward movement of the press beam 28, a free space (press shaft) is created in front of the slot 36 of the shaped piece 37 ′, into which the tobacco falls from the storage space 25. During the subsequent forward movement of the press beam, the tobacco that has entered the free space is pushed together and pressed into the slot of the shaped piece. So that the tobacco fibers located in the free space do not swell upwards out of it during the press beam advance, a pressure bracket 39 is provided which is pressed onto the tobacco during this advance. The movement-compliant movement of this pressure bracket takes place through a coupling linkage 40 (see FIG. 5), which is in operative connection with an angle piece 41 connected to the pressure beam 28.

Eine scharfkantige Ausbildung der Preßbalken-Vorderkante 42, in Verbindung mit der oberen Vorderkante 43 des Schlitzes 36 bewirkt, daß überstehende Tabakfasern beim Preßvorgang abgeschnitten werden. Nachdem vollständigen Eintauchen des Preßbalkens in den Schlitz des Formstückes ist somit ein exakt runder Tabakstrang geformt worden.A sharp-edged design of the press beam front edge 42, in connection with the upper front edge 43 of the slot 36, causes protruding tobacco fibers to be cut off during the pressing process. After the plunger has been completely immersed in the slot of the fitting, an exactly round tobacco rod has been formed.

Um die zu pressende Tabakmenge individuell an die geforderte Festigkeit und Dichte des Tabakstranges, die u. a. auch von der Struktur des verarbeitenden Tabaks abhängig ist, weiterhin anpassen zu können, kann eine Verstellmöglichkeit 44 der hinteren Seitenwand 26 des Tabakvorratsraumes vorgesehen sein. Durch die links- bzw. rechtsseitige Verschiebung dieser Wand wird der Eintrittsbereich des Tabaks in den bei zurückgezogenem Preßbalken gebildeten Freiraum, in den der für eine Zigarettenfüllung zu pressende Tabak hineinfällt, variiert und somit die zu pressende Tabakmenge verändert.To the amount of tobacco to be pressed individually to the required strength and density of the tobacco rod, which u. a. is also dependent on the structure of the processing tobacco to be able to adapt further, an adjustment 44 of the rear side wall 26 of the tobacco storage room can be provided. By shifting this wall to the left or to the right, the entry area of the tobacco is varied in the space formed when the press beam is retracted, into which the tobacco to be pressed for a cigarette filling falls, and thus the amount of tobacco to be pressed is changed.

In der Hohlkehle des Formstückes ist ein angepaßter, ebenfalls halbrunder, hohler Ausstoßlöffel 45 vorgesehen, dessen Länge der Breite des Preßbalkens, d.h. der Länge des zu formenden Tabakstranges entspricht. Die Innenseite 46 des Ausstoßlöffels, die mit dem Tabakstrang in Berührung steht, ist mit einer gestuften, schuppenartigen Oberfläche versehen, die zum einen beim Ausschieben des Tabakstranges mitsamt des Löffels aus dem Preßraum 47 eine gute Mitnahme des Tabakstranges bewirkt und zum anderen gewährleistet, daß der Löffel einfach wieder aus der gefüllten Zigarettenhülse herausgezogen werden kann, ohne daß der Tabakstrang mit zurücktransportiert wird. Der hohle Ausstoßlöffel geht an seiner Druckseite 48 in einen Vollmaterial-Ansatz 49 über, dessen Durchmesser dem Durchmesser des Preßraumes 47 entspricht.An adapted, also semicircular, hollow discharge spoon 45 is provided in the fillet of the molding, the length of which corresponds to the width of the press beam, i.e. corresponds to the length of the tobacco rod to be shaped. The inside 46 of the discharge spoon, which is in contact with the tobacco rod, is provided with a stepped, scale-like surface which, on the one hand, causes the tobacco rod to be carried along when the tobacco rod is pushed out together with the spoon from the press chamber 47, and on the other hand ensures that the Spoons can easily be pulled out of the filled cigarette tube again without the tobacco rod being transported back with it. The hollow discharge spoon merges on its pressure side 48 into a solid material attachment 49, the diameter of which corresponds to the diameter of the press space 47.

In der Grundstellung (Formen und Pressen des Tabakstranges) befindet sich der Ausstoßlöffel vollständig in der Hohlkehle 38 des Formstückes 37. Nachdem der Tabakstrang geformt ist, wird der Preßbalken ein geringes Stück über die Endstellung zurückbewegt (Übertotpunktstellung), um den Tabakstrang (Ausstoßlöffel) vom Preßdruck zu entlasten. Anschließend wird der Tabakstrang durch seitliche Verschiebung des Ausstoßlöffels aus dem Preßraum 47 herausgeschoben. Der Antrieb des Ausstoßlöffels erfolgt dabei durch den Motor 8 der über ein Rädergetriebe 50 eine Gewinde- Spindel 51 antreibt. Auf der Spindel befindet sich ein Gleitstück 52, das durch eine Führungsstange 53 gegen Verdrehung gesichert ist und das mit der rückwärtigen Verlängerung 54 des Ausstoßlöffels verbunden ist. Endschalter 55, 56 erkennen und signalisieren die jeweilige Stellung des Gleitstückes und damit des Ausstoßlöffels zur elektrischen/elektronischen Steuerung 9 und bewirken das ablaufgerechte Ein- und Ausschalten des Antriebsmotors 8. In der linken Seitenwand 4 ist in Verlängerung des Preßraumes 47 (des Ausstoßlöffels) eine Öffnung 57 vorgesehen, vor der sich der Zigarettenhülsen-Aufnahmestutzen 58 (Füllrohr) befindet (sh. Fig. 2, 3, 8). Der Aufnahmestutzen besteht im wesentlichen aus einem dünnwandigen, kurzen Rohrstück 59, das mit einem Befestigungsflansch 60 versehen ist. Vor dem bzw. über dem Füllrohr ist eine mit federnden Zentrierzungen 61 versehene Zigarettenhülsen-Zentriereinrichtung 62 vorgesehen. Zum Aufschieben einer Leerhülse auf das Füllrohr wird der Hülsenanfang zunächst über die in einer Spitze zusammenlaufenden Zungenenden geschoben, die bei weiterer Bewegung auf das Füllrohr zu durch dieses gespreizt werden und die Hülse in eine exakt runde Form drücken. Die Zentriereinrichtung 62 wird dabei mit auf dem Aufnahmestutzen (Füllrohr) verschoben. Dazu ist die Zentriereinrichtung über ein Gestänge 63 mit dem weiter unten näher beschriebenen Schlitten 64 gekoppelt. Durch entsprechende beabstandete Mitnehmer 65,65' erfolgt die zwangsläufige Verschiebung der Zentriereinrichtung 62 nur in einem Teilbereich der Schlittenverschiebung. In Fortführung der Verschiebung der Zigarettenhülse wird diese dann auf das Rohrstück 59 aufgeschoben. Die Formung und Zentrierung der Zigarettenhülsen ist erforderlich, weil die dünnwandigen Papierhülsen nicht immer in exakt runder Form vorliegen, sondern oftmals oval verformt sind und die Achse von aufzuschiebender Leerhülse und Füllrohr nicht immer genau übereinstimmt. Die Zuführung der Zigaretten-Leerhülsen 66 vom Vorratsbehälter 11 zum Aufnahmestutzen 58 (Füllrohr) erfolgt mittels des Schlittens 64. Es ist eine verschwenkbare Greifeinrichtung 67 vorgesehen, die die Leerhülsen aus dem Vorratsbehälter einzeln auf den Schlitten befördert. Die Greifeinrichtung besteht im wesentlichen aus entsprechend der Hülsenlänge beabstandet angeordneten Segmenten, bzw. einem Segmentblock in dem eine dem Hülsendurchmesser entsprechende Ausnehmung 68 eingeformt ist.In the basic position (shaping and pressing the tobacco rod), the discharge spoon is located completely in the groove 38 of the shaped piece 37. After the tobacco rod has been formed, the pressure beam is moved back a little bit beyond the end position (dead center position) to the tobacco rod (discharge spoon) To relieve pressure. The tobacco rod is then pushed out of the press space 47 by lateral displacement of the discharge spoon. The discharge spoon is driven by the motor 8, which drives a threaded spindle 51 via a gear mechanism 50. On the spindle there is a slide 52 which is secured against rotation by a guide rod 53 and which is connected to the rear extension 54 of the discharge spoon. Limit switches 55, 56 recognize and signal the respective position of the slider and thus of the discharge spoon for electrical / electronic control 9 and cause the drive motor 8 to be switched on and off in accordance with the sequence. In the left side wall 4 there is an extension of the pressing space 47 (the discharge spoon) Opening 57 is provided, in front of which the cigarette tube receptacle 58 (filling tube) is located (see FIGS. 2, 3, 8). The receptacle essentially consists of a thin-walled, short pipe section 59, which is provided with a mounting flange 60. A cigarette tube centering device 62 provided with resilient centering tongues 61 is provided in front of or above the filling tube. To push an empty sleeve onto the filling tube, the beginning of the sleeve is first pushed over the tongue ends converging in a tip, which are further spread towards the filling tube and push the sleeve into an exactly round shape. The centering device 62 is also moved on the receptacle (filler pipe). For this purpose, the centering device is connected to the Coupled carriage 64 described below. By means of correspondingly spaced drivers 65, 65 ', the inevitable displacement of the centering device 62 takes place only in a partial area of the carriage displacement. Continuing the displacement of the cigarette tube, it is then pushed onto the tube piece 59. The shaping and centering of the cigarette tubes is necessary because the thin-walled paper tubes are not always in an exactly round shape, but are often oval in shape and the axis of the empty tube and filling tube to be pushed open does not always match exactly. The feeding of the empty cigarette tubes 66 from the storage container 11 to the receptacle 58 (filling tube) takes place by means of the slide 64. A pivotable gripping device 67 is provided which conveys the empty tubes from the storage container individually onto the slide. The gripping device essentially consists of segments arranged at a distance corresponding to the sleeve length, or a segment block in which a recess 68 corresponding to the sleeve diameter is formed.

In der Ausgangsstellung (Fig. 7) verdeckt die Außenkante 69 des Segmentblockes die Austrittsöffnung 70 des Vorratsbehälters 11. Bei Verschwenkung der Greifeinrichtung gelangt die Ausnehmung 68 vor die Austrittsöffnung und eine einzelne Leerhülse 66 kann in die Ausnehmung hineinrollen. Bei der anschließenden Rückwärtsverschwenkung der Greifeinrichtung gelangen die Außenkanten 69 wieder vor die Öffnung 70 und verhindern den Austritt weiterer Leerhülsen. Während der Verschwenkung der Greifeinrichtung in ihre Grundstellung rollt die in der Ausnehmung befindliche Leerhülse dann aus dieser heraus und fällt auf den unterhalb befindlichen Schlitten 64. Der Schlitten ist mit einer schalenförmigen Auffangwanne 71 und diese mit einem linksseitigen Wandteil 72 versehen. Durch Verschiebung des Schlittens in Richtung auf den Aufnahmestutzen 58 zu wird die Leerhülse mitgenommen, mittels der bereits weiter oben erläuterten Zentriereinrichtung 62 in Bezug auf den Aufnahmestutzen zentriert, exakt rund geformt und auf diesen aufgeschoben. In dieser Position verharrt der Schlitten zunächst, wobei sich das Leerhülsenende weiterhin gegen das Wandteil 72 abstützt. Anschließend erfolgt das Ausschieben des geformten Tabakstranges mittels des Ausstoßlöffels durch den Aufnahmestutzen 58 hindurch in die Zigaretten-Leerhülse. Während der letzten Millimeter des Füllhubes drückt der Ausstoßlöffel gegen das Filterende der Zigarettenhülse und schiebt diese vom Aufnahmestutzen (Füllrohr) herunter, wobei gleichzeitig der Schlitten 64 mit seitwärts verschoben wird. Dies wird ermöglicht durch entsprechendes Spiel in dem Antriebsgestänge 73 des Schlittens. Wenn das erfolgt ist, wird der Ausstoßlöffel zurückgezogen, wobei der Tabakstrang in der Zigarettenhülse zurückbleibt. Dabei drückt nun ein federndes Druckstück 74 gegen den Zigarettenanfang und verhindert eine Zurückbewegung der gefüllten Zigarette.In the starting position (FIG. 7), the outer edge 69 of the segment block covers the outlet opening 70 of the storage container 11. When the gripping device is pivoted, the recess 68 reaches the outlet opening and a single empty sleeve 66 can roll into the recess. When the gripping device is subsequently pivoted backwards, the outer edges 69 again come in front of the opening 70 and prevent further empty sleeves from escaping. During the pivoting of the gripping device into its basic position, the empty sleeve located in the recess then rolls out of it and falls onto the slide 64 located below. The slide is provided with a bowl-shaped collecting trough 71 and this is provided with a wall part 72 on the left. By moving the slide in the direction of the receiving socket 58, the empty sleeve is taken along, centered with respect to the receiving nozzle by means of the centering device 62 already explained above, shaped exactly round and pushed onto it. The carriage initially remains in this position, the empty sleeve end still being supported against the wall part 72. The shaped tobacco rod is then pushed out by means of the ejection spoon through the receptacle 58 into the empty cigarette tube. During the last millimeter of the filling stroke, the ejection spoon presses against the filter end of the cigarette tube and pushes it down from the receptacle (filling tube), the slide 64 being simultaneously moved sideways. This is made possible by corresponding play in the drive linkage 73 of the slide. When this is done, the spoon is withdrawn, leaving the tobacco rod in the cigarette tube. A resilient pressure piece 74 now presses against the beginning of the cigarette and prevents the filled cigarette from moving back.

Anschließend wird der Schlitten 64 wieder in die Ausgangsposition verschoben und gleichzeitig die Zentriereinrichtung 62 über das Gestänge 63 in ihre vordere in der Fig. 3 dargestellte Position verschoben, wobei in dieser Stellung des Schlittens eine erneute Verschwenkung der Greifeinrichtung 67 eingeleitet wird. An der Greifeinrichtung sind Abstreiffinger 75 angebracht, die bei deren Verschwenkung durch entsprechende Schlitze in der Schlitten-Wanne 71 hindurchgreifen, die gefüllte Zigarette 76 aus der Wanne heben und in einen Auffangbehälter 77 hineinrollen. Der Auffangbehälter ist als aus dem Gerät entnehmbare Schale ausgebildet. Während die gefüllte Zigarette von der Schlitten-Wanne befördert wird, gelangt die Ausnehmung 68 der Greifeinrichtung in den Bereich der Austrittsöffnung 70, eine weitere Leerhülse rollt hinein und der Füllablauf beginnt von neuem.The carriage 64 is then moved back to the starting position and at the same time the centering device 62 is displaced via the linkage 63 into its front position shown in FIG. 3, with the gripping device 67 being pivoted again in this position of the carriage. Scraper fingers 75 are attached to the gripping device. When they are pivoted, they reach through corresponding slots in the slide tray 71, lift the filled cigarette 76 out of the tray and roll into a collecting container 77. The collecting container is designed as a shell that can be removed from the device. While the filled cigarette is being transported by the sled tub, the recess 68 of the gripping device reaches the area of the outlet opening 70, a further empty tube rolls in and the filling process begins again.

Die Bewegung und Verschiebung des Schlittens 64 erfolgt durch ein mit dem Gleitstück 52 auf der Gewinde-Spindel 51 gekoppeltes Hebelgestänge 73, 73', 73".The movement and displacement of the carriage 64 takes place by means of a lever linkage 73, 73 ', 73 ″ coupled to the slide 52 on the threaded spindle 51.

Die Bewegung und Verschwenkung der Greifeinrichtung 67 erfolgt über ein Hebelgestänge 78, 78' das mit dem am Preßbalken 28 befestigten Winkelstück 41 in Verbindung steht. Weiterhin ist vorgesehen, daß der Vorratsbehälter 11 während eines Arbeitszyklus' um ein geringes Stück angehoben und ruckartig abgesenkt wird. Dadurch wird gewährleistet, daß die Leerhülsen immer einwandfrei in die vordere Entnahmeposition nachrutschen auch wenn die Hülsen in ovaler Form vorliegen. Das Anheben und Absenken erfolgt durch eine Kipphebel-Anordnung 79 an der Unterseite des Vorratsbehälters, die ebenfalls von dem Winkelstück 41 betätigt wird.The movement and pivoting of the gripping device 67 takes place via a lever linkage 78, 78 'which is connected to the angle piece 41 fastened to the press beam 28. Furthermore, it is provided that the storage container 11 is raised by a small amount during a work cycle and lowered suddenly. This ensures that the empty sleeves always slide into the front removal position even when the sleeves are oval in shape. The lifting and lowering is carried out by a rocker arm arrangement 79 on the underside of the storage container, which is also actuated by the angle piece 41.

Im Bereich der Austrittsöffnung des Leerhülsen-Vorratsbehälters ist eine Überwachungseinrichtung 80 (Schalter, Sensor o. ä.) vorgesehen, womit die Entnahme der letzten Leerhülse erkannt und das Gerät anschließend ausgeschaltet wird. In der Anordnung des Ausführungsbeispieles ist vorgesehen, daß nach dem Einrollen der Leerhülse 66 in die Ausnehmung 68 der Greifeinrichtung 67 diese noch ein Stück nach oben geschwenkt wird, so daß die Leerhülse gegen den Schaltbügel des Schalters 80 gedrückt wird, d. h. bei vorhandener Leerhülse wird der Schalter betätigt und bei nichtvorhandener Leerhülse erfolgt keine Betätigung. Durch diese Anordnung wird gleichzeitig die seitenrichtige Lage des Filterendes der Leerhülse erkannt, da der Schalter im Bereich des Filterendes angebracht ist. Bei richtig eingelegter Leerhülse trifft der Schalter auf das Filterende und wird betätigt-bei falsch eingelegter Leerhülse trifft der Schalter auf die hohle Papierhülse, die zusammengedrückt wird, wobei keine Schalterbetätigung erfolgt und das Gerät ausgeschaltet und eine Störung signalisiert wird.A monitoring device 80 (switch, sensor or the like) is provided in the area of the outlet opening of the empty tube storage container, by means of which the removal of the last empty tube is recognized and the device is then switched off. In the arrangement of the exemplary embodiment, it is provided that after the empty sleeve 66 has been rolled into the recess 68 of the gripping device 67, it is pivoted upward a little, so that the empty sleeve is pressed against the switching bracket of the switch 80, that is to say if the empty sleeve is present The switch is actuated and there is no actuation if there is no empty sleeve. With this arrangement, the correct position of the filter end of the empty sleeve is recognized at the same time, since the switch is attached in the area of the filter end. If the empty sleeve is inserted correctly, the switch hits the end of the filter and is actuated - if the empty sleeve is inserted incorrectly, the switch hits the hollow paper sleeve, which is pressed together, with no switch actuation and the device switched off and a fault is signaled.

Die Abmessungen von Tabak-, Leerhülsen-Vorratsbehälter und Auffangbehälter sind so ausgelegt, daß eine größere Anzahl von Zigaretten, z. B. 20 oder mehr, selbsttätig ohne manuelle Eingriffe nacheinander erstellt werden können.The dimensions of tobacco, empty tube storage container and collection container are designed so that a larger number of cigarettes, for. B. 20 or more, can be created automatically without manual intervention one after the other.

Zur Erhöhung des Volumens des Tabakvorrates kann vorgesehen sein, daß auf den Einfülltrichter 10 ein Aufsatz 81 aufsteckbar ist. Dieser Aufsatz kann ggfs. auch als hochklappbarer Faltenbalg ausgebildet sein.To increase the volume of the tobacco supply, it can be provided that an attachment 81 can be plugged onto the hopper 10. This attachment can optionally also be designed as a fold-up bellows.

Angetrieben wird das Gerät des Ausführungsbeispieles von zwei Elektromotoren 7, 8, die mittels elektrischer Verschaltung und Steuerung entsprechend den vorgesehenen Bewegungsabläufen ein- bzw. ausgeschaltet werden. Selbstverständlich kann auch nur ein einziger Antriebsmotor vorgesehen sein, der mittels entsprechender Kupplungen und Getriebeanordnungen die jeweiligen Bewegungsabläufe bewirkt oder es können mehrere Motore mit entsprechender elektrischer Verschaltung vorgesehen sein.The device of the exemplary embodiment is driven by two electric motors 7, 8, which are switched on and off by means of electrical switching and control in accordance with the intended movement sequences. Of course, only a single drive motor can also be provided, which effects the respective movement sequences by means of corresponding couplings and gear arrangements, or a plurality of motors can be provided with a corresponding electrical connection.

Der Vollständigkeit halber wird der Ablauf der Erstellung der Zigaretten mit dem erfindungsgemäßen Gerät nachstehend zusammenhängend erläutert.For the sake of completeness, the sequence of creating the cigarettes with the device according to the invention is explained below in a coherent manner.

Zunächst werden Filterzigaretten-Leerhülsen 66 in den Leerhülsen-Vorratsbehälter 11 eingelegt. Zur Erleichterung des Einfüllens ist derFirst, filter cigarette empty tubes 66 are inserted into the empty tube storage container 11. To facilitate filling, the

Vorratsbehälter mit einem abnehmbaren Deckel 12, vorzugsweise Klarsichtdeckel, versehen. Anschließend wird eine Tabakmenge in den Tabakeinfülltrichter 10 gefüllt. Anschließend wird durch hier nicht näher dargestellte Schalter und/oder Taster das Gerät eingeschaltet und in Betrieb gesetzt.Storage container provided with a removable lid 12, preferably a transparent lid. A quantity of tobacco is then filled into the tobacco hopper 10. The device is then switched on and put into operation by switches and / or buttons not shown here.

Der Preßbalken 28 befindet sich dabei in seiner hinteren Stellung (Bildung des Freiraumes zur Tabakaufnahme, Preßschacht offen), wobei diese Stellung durch einen hier nicht näher dargestellten Schalter/Sensor überwacht und der Steuereinrichtung 9 signalisiert wird. Bei Anlauf des Gerätes werden dann die Dosierwellen 13, 14 in Drehung versetzt, wobei Tabak in den Tabak- Vorratsraum und den Freiraum/Preßschacht gefördert wird.The press beam 28 is in its rear position (formation of the space for tobacco reception, press shaft open), this position being monitored by a switch / sensor (not shown here) and signaled to the control device 9. When the device starts up, the metering shafts 13, 14 are then rotated, with tobacco being conveyed into the tobacco storage room and the free space / press shaft.

Anschließend wird der Preßbalken in die Preßstellung verschoben, wobei gleichzeitig ein Bügel 39 auf den Tabak im Preßschacht gedrückt wird.The press bar is then moved into the press position, a bracket 39 being pressed onto the tobacco in the press shaft at the same time.

Hat der Preßbalken 28 seine vordere Preßstellung erreicht und somit den Tabakstrang geformt, wird er ein kurzes Stück zurückbewegt und verharrt in dieser Stellung. Auch diese Stellung wird mittels eines Schalters/Sensors erkannt und der Steuerung 9 signalisiert, die die Abschaltung des Preßbalkenantriebes bewirkt. Der geformte Tabakstrang ist dadurch vom Preßdruck entlastet und kann ausgeschoben werden, wie weiter unten erläutert.When the pressure beam 28 has reached its front pressing position and has thus formed the tobacco rod, it is moved back a short distance and remains in this position. This position is also recognized by means of a switch / sensor and signaled to the controller 9, which causes the pressure beam drive to be switched off. The molded tobacco rod is thus relieved of the pressure and can be pushed out, as explained below.

Während diese Bewegungen abliefen, wurde die Greifeinrichtung 67 verschwenkt, (bei der Bewegung des Preßbalkens) nahm eine Leerhülse 66 in ihren Ausnehmungen 68 auf und transportierte diese bei ihrer Rückwärtsverschwenkung auf den Transportschlitten 64, 71, der sich dabei in seiner äußersten linken Position (Fig. 3) befindet.While these movements were taking place, the gripping device 67 was swiveled (during the movement of the press beam) received an empty sleeve 66 in its recesses 68 and, when it was pivoted backwards, transported it on the transport carriage 64, 71, which in the process was in its extreme left position (FIG 3).

Anschließend wird die Transportschlitten-Bewegung eingeleitet und der Schlitten 64 transportiert die Leerhülse in Richtung auf den Aufnahmestutzen 58 zu. Kurz vor Erreichen der Endstellung gelangen die federnden Zungen 61 der Zentriereinrichtung 62 in die Hülsenöffnung, formen und zentrieren die Hülse, die in weiterer Fortführung der Schlittenbewegung auf den Aufnahmestutzen 58 geschoben wird.The transport carriage movement is then initiated and the carriage 64 transports the empty sleeve in the direction of the receiving socket 58. Shortly before the end position is reached, the resilient tongues 61 of the centering device 62 enter the sleeve opening, shape and center the sleeve, which is pushed onto the receiving connector 58 as the slide movement continues.

Sodann beginnt die durch den Motor 8 und einen zugeordneten Spindeltrieb 51, 52 bewirkte Bewegung des Ausstoßlöffels 45, der seitwärts verschoben wird und dabei den Tabakstrang durch den Aufnahmestutzen hindurch in die Leerhülse einschiebt. Dabei wird der Ausstoßlöffel mit in die Hülse eingeschoben. Beim Einschieben des Tabakstranges, sowie des Ausstoßlöffels, wird durch deren Aufstoßen auf das Zigarettenhülsenende (Filterstück) die Zigarette mitsamt dem Transportschlitten seitwärts verschoben, wobei die Zigarettenhülse vom Aufnahmestutzen heruntergeschoben wird. Anschließend wird der Ausstoßlöffel wieder in seine Ausgangsstellung in den Preßschacht zurückgezogen. Die gefüllte Zigarette ist nunmehr vollständig von der Fülleinrichtung getrennt und der Transport-Schlitten 64 wird in seine Ausgangsposition (äußerste linke Endstellung) verschoben, wobei die fertige Zigarette mit verschoben wird. Gleichzeitig werden auch die Federzungen 61 der Zentriereinrichtung 62, die über ein Gestänge 63 mit dem Schlitten 64 gekoppelt ist, vom Aufnahmestutzen heruntergezogen. Dann wird wiederum die Verschwenkung der Greifeinrichtung 67 eingeleitet, wobei an dieser angeordnete Abstreiffinger 75 die gefüllte Zigarette vom Schlitten in einen Auffangbehälter 77 rollen.Then begins the movement of the discharge spoon 45 caused by the motor 8 and an associated spindle drive 51, 52, which is moved sideways and thereby pushes the tobacco rod through the receptacle into the empty tube. The ejection spoon is pushed into the sleeve. When pushing in the tobacco rod and the ejection spoon, the cigarette and the transport carriage are moved sideways by pushing them onto the end of the cigarette tube (filter piece), whereby the cigarette tube is pushed down from the socket. The discharge spoon is then pulled back into its starting position in the press shaft. The filled cigarette is now completely separated from the filling device and the transport carriage 64 is displaced into its starting position (extreme left end position), the finished cigarette also being displaced. At the same time, the spring tongues 61 of the centering device 62, which is coupled to the carriage 64 via a linkage 63, are pulled down from the receiving connection piece. Then, in turn, the pivoting of the gripping device 67 is initiated, the scraper fingers 75 arranged on the scraper finger rolling the filled cigarette from the carriage into a collecting container 77.

Während der Verschwenkung der Greifeinrichtung, die in Abhängigkeit von der Preßbalkenbewegung abläuft bzw. hierdurch hervorgerufen wird, wurde der Preßschacht bereits wieder geöffnet, die Dosierwellen in Bewegung gesetzt und Tabak konnte in diesen eintreten.During the swiveling of the gripping device, which takes place as a function of the press beam movement or is caused thereby, the press shaft was already opened again, the metering shafts were set in motion and tobacco could enter it.

Der weitere Ablauf erfolgt automatisch in der bereits vorstehend erläuterten Reihenfolge bis das Gerät entweder ausgeschaltet wird, oder die Überwachungseinrichtung 80 am Leerhülsen-Vorratsbehälter 11 erkennt, daß keine zu füllende Zigarettenhülsen mehr zur Verfügung stehen.The rest of the process takes place automatically in the order already explained above until the device is either switched off or the monitoring device 80 on the empty tube storage container 11 detects that there are no more cigarette tubes to be filled.
