This results in a change in the relative position of the relevant touch flag 34 with respect to a transverse light barrier 38. This is interrupted. An error signal is triggered.
  • the is Movement amplitude of the feeler flag 34 is limited, namely by a transverse stop rod 39 common to all feeler flags. This passes through a (circular) hole 40 in the feeler flags. The edge of the hole 40 is in contact with the stop rod 39 as soon as the touch flag enters the relevant shaft 12 due to the lack of cigarettes. As soon as the error has been eliminated and the shaft in question has been provided with an uninterrupted sequence of cigarettes, the touch flag is automatically pivoted back into the starting position (solid line in FIG. 2) as a result of the cigarettes being conveyed.

  • the transmission described above is housed in an elongated transmission housing 45 on the outside of the front wall 24.
  • the vibrating bars 41 within the magazine, namely at the entry end of the shafts 12, are designed in a special way. On the outer circumference there are elevations and depressions running in the longitudinal direction in the form of grooves 46. These are formed in the present vibrating bars 41 only in a central region. At the ends of the vibrating bars - in the present embodiment at both ends - cross-sectional tapering 47 and 48 are formed. These conically tapering ends of the vibrating bars 46 ensure that the end areas of the cigarettes 13 are not mechanically stressed by the vibrating bars and consequently no fine tobacco parts are pressed out of the cigarettes.
  • the design of the vibrating rods 41 in the above sense therefore has the consequence that tobacco leakage at the ends of the cigarettes is avoided as a result of the vibrating movements. If cigarettes are processed with a filter, it is sufficient if a cross-sectional taper is formed only at one end - at the end remote from the cigarette filter.
  • the individual devices for ensuring a trouble-free flow of cigarettes within the chutes 12, that is to say the support rod 26, the feeler tabs 34 and the vibrating bars 41, can also be used independently of one another.

Description

Die Erfindung betrifft eine Vorrichtung zum Verpacken von Zigaretten, gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a device for packaging cigarettes, according to the preamble of patent claim 1.

Eine derartige Vorrichtung ist aus der DE-C-508 641 bekannt. Dadurch, daß die Tragstange zentral bzw. mittig in bezug auf die Längserstreckung der Zigaretten angeordnet ist, muß diese bis auf Höhe der oberen Stützfläche der Stößel angehoben werden, bevor diese vollständig aus den Schachten des Zigaretten-Magazins zurückgezogen werden können, anderenfalls bestünde die Gefahr, daß die Zigaretten im wesentlichen ohne Behinderung durch die Tragstange über die freie Oberkante der Stößel infolge ihres Eigengewichts bis auf die untere Auflage abkippen bzw. nachfallen mit der Folge, daß Verklemmungen, Schrägstellungen etc. der Zigaretten auftreten. Dementsprechend ist die Arbeitsgeschwindigkeit der bekannten Vorrichtung begrenzt.Such a device is known from DE-C-508 641. The fact that the support rod is arranged centrally or centrally with respect to the longitudinal extension of the cigarettes, this must be raised to the level of the upper support surface of the plunger before they can be completely withdrawn from the chutes of the cigarette magazine, otherwise there would be a risk that the cigarettes tip over or fall down without any hindrance by the carrying rod over the free upper edge of the plunger due to their own weight, with the result that jams, inclinations, etc. of the cigarettes occur. Accordingly, the working speed of the known device is limited.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der bekannten Art so weiterzuentwickeln, daß bei höheren Arbeitsgeschwindigkeiten ein geordneter Durchlauf der Zigaretten vom Eintritt in die Schächte des Zigaretten-Magazins bis zum Ausschub aus diesen gewährleistet ist.The invention has for its object to develop a device of the known type so that an orderly passage of the cigarettes from entry into the shafts of the cigarette magazine until ejection is ensured at higher working speeds.

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

Bei der erfindungsgemäßen Konstruktion werden demnach die nachlaufenden Zigaretten stufenweise bis zum Erreichen der unteren Auflage abgesenkt, und zwar unter wechselnder Schrägstellung der Zigaretten, indem diese zunächst an einem Ende auf niedrigerem Niveau und sodann am anderen Ende auf nochmals niedrigerem Niveau abgestützt werden. Die Enden der sich zurückziehenden Stößel bilden dabei eine erste Abstützung der zugekehrten Enden der Zigaretten, deren gegenüberliegendes Ende (zeitweilig) auf einem mit geringerem Abstand von der unteren Auflage sich erstreckenden Tragstab aufliegen. Sobald die Stößel vollständig aus den Schächten zurückgezogen sind, werden die diesen zugekehrten Enden der Zigaretten weiter abgesenkt, unterhalb der durch den Tragstab vorgegebenen Höhe, insbesondere bis auf die Auflage. Danach wird der Tragstab aus seiner Stützpositon herausbewegt, so daß die Zigaretten vollständig die untere Endlage erreichen.In the construction according to the invention, the trailing cigarettes are accordingly lowered step by step until the lower support is reached, and this with changing inclination of the cigarettes, by first supporting them at a lower level at one end and then at an even lower level at the other end. The ends of the retracting plungers form a first support of the facing ends of the cigarettes, the opposite end of which (temporarily) rest on a support rod which extends at a shorter distance from the lower support. As soon as the plungers are completely withdrawn from the shafts, the ends of the cigarettes facing them are lowered further, below the height specified by the support rod, in particular up to the support. The support rod is then moved out of its support position so that the cigarettes completely reach the lower end position.

Bei diesem stufenweisen Absenkvorgang unter abwechselnder Bewegung der einen und anderen Enden werden mechanische Beanspruchungen der Zigaretten, aber auch Verkantungen, Schiefstellungen etc. vermieden. Die Zigaretten in den Schächten erfahren eine Auflockerungsbeeinflussung.In this step-by-step lowering process with alternating movement of the one and the other ends, mechanical stresses on the cigarettes, but also canting, misalignments etc. are avoided. The cigarettes in the chutes are affected by the loosening.

Weitere Merkmale der Erfindung, die einen ordnungsgemäßen Zigarettenfluß innerhalb der Schächte des Zigaretten-Magazins fördern, sind in den Unteransprüchen beschrieben.Further features of the invention that promote proper cigarette flow within the chutes of the cigarette magazine are described in the subclaims.

Nachstehend wird ein Ausführungsbeispiel einer erfindungsgemäß ausgebildeten Vorrichtung anhand der beigefügten Zeichnung näher erläutert. Es zeigen:

  • Fig. 1 ein Magazin für Zigaretten in Vorderansicht,
  • Fig. 2 das Magazin gemäß Fig. 1 in einem Vertikalschnitt durch einen Schacht, in vergrößertem Maßstab,
  • Fig. 3 den unteren Bereich eines Schachtes im Vertikalschnitt,
  • Fig. 4 eine Darstellung entsprechend Fig. 3 bei veränderter Relativstellung der Zigaretten und einzelner Organe.
An exemplary embodiment of a device designed according to the invention is explained in more detail below with reference to the attached drawing. Show it:
  • 1 is a front view of a magazine for cigarettes,
  • 2 shows the magazine according to FIG. 1 in a vertical section through a shaft, on an enlarged scale,
  • 3 shows the lower region of a shaft in vertical section,
  • Fig. 4 is an illustration corresponding to Fig. 3 with changed relative position of the cigarettes and individual organs.

Ein Zigaretten-Magazin 10 in der vorliegenden Ausführung ist einer im einzelnen nicht dargestellten Verpackungsmaschine für Zigaretten zugeordnet. Die Zigaretten werden - von einer Herstellmaschine (nicht gezeigt) - in einen trichterförmigen Behälter 11 des Zigaretten-Magazins 10 von oben her eingefüllt. In diesem Behälter wird eine Anzahl von Schächten 12 gebildet, nämlich aufrechte, langgestreckte Kanäle, in denen jeweils einzelne Zigaretten 13 in einer Reihe übereinanderliegend Aufnahme finden. Die Zigaretten liegen normalerweise in Dichtlage in einem derartigen Schacht 12. Diese sind durch Schachtwände 14 gegeneinander abgeteilt. Bei dem vorliegenden Ausführungsbeispiel haben die Schachtwände einen in Richtung nach unten konvergierenden Querschnitt, laufen demnach spitz zu. Des weiteren sind die Schachtwände 14 im unteren Bereich bogenförmig gestaltet, so daß auch die von diesen begrenzten Schächte 12 eine bogenförmige Gestalt im unteren Bereich aufweisen.A cigarette magazine 10 in the present embodiment is assigned to a packaging machine for cigarettes, not shown in detail. The cigarettes are - from a manufacturing machine (not shown) - filled into a funnel-shaped container 11 of the cigarette magazine 10 from above. In this container, a number of shafts 12 are formed, namely upright, elongated channels, in which individual cigarettes 13 are received one above the other in a row. The cigarettes are normally in a sealed position in such a shaft 12. These are partitioned off from one another by shaft walls 14. In the present exemplary embodiment, the shaft walls have a cross section which converges in the downward direction and accordingly taper to a point. Furthermore, the shaft walls 14 are curved in the lower region, so that the shafts 12 delimited by these also have an arched shape in the lower region.

In dem vorliegenden Zigaretten-Magazin sind zwei Gruppen 15 und 16 von Schächten 12 gebildet. Jede dient zur Bildung einer Zigaretten-Gruppe entsprechend der Anzahl der in einer Zigaretten-Packung aufzunehmenden Anzahl von Zigaretten.In the present cigarette magazine, two groups 15 and 16 of shafts 12 are formed. Each is used to form a group of cigarettes according to the number of cigarettes to be contained in a pack of cigarettes.

Die unteren Zigaretten 13 in jedem Schacht 12 sind abgestützt auf einer im vorliegenden Fall schrägliegenden Auflage in Gestalt einer Tragplatte 17 bzw. 18. Diese sind quer (senkrecht) zu den (schräg gerichteten) Schachtwänden 14 angeordnet und dadurch ihrerseits schräg gerichtet unter einem Winkel zueinander.The lower cigarettes 13 in each shaft 12 are supported on an inclined support in the form of a support plate 17 or 18 in the present case. These are arranged transversely (perpendicularly) to the (obliquely directed) shaft walls 14 and thereby in turn directed obliquely at an angle to one another .

Die Zigaretten 13 gelangen im wesentlichen unter Eigengewicht in einen der Schächte 12 und bilden in diesem eine fortlaufende Reihe von übereinander angeordneten Zigaretten 13. Am unteren Ende der Schächte 12 wird aus den Gruppen 15 und 16 der Schächte 12 jeweils eine Anzahl der unteren, auf den Tragplatten 17 und 18 aufliegenden Zigaretten 13 abgefördert, und zwar eine dem Inhalt einer Zigarettenpackung entsprechende Zigaretten-Gruppe. Bei dem vorliegenden Ausführungsbeispiel ist vorgesehen, daß eine Zigaretten-Gruppe aus den jeweils drei unteren Zigaretten 13 eines Schachtes 12 aus diesem ausgestoßen und abgefördert werden.The cigarettes 13 come essentially under their own weight into one of the shafts 12 and form a continuous row of cigarettes 13 arranged one above the other in the latter. At the lower end of the shafts 12, groups 15 and 16 of the shafts 12 each have a number of the lower ones Support plates 17 and 18 transported cigarettes 13, namely a cigarette group corresponding to the content of a cigarette pack. In the present exemplary embodiment it is provided that a cigarette group is ejected from the respective three lower cigarettes 13 of a shaft 12 and be promoted.

Für den Ausschub einer entsprechenden Anzahl von Zigaretten 13 je Schacht 12 ist ein Schieber 19 vorgesehen mit einer der Anzahl der zu entleerenden Schächte 12 entsprechenden Anzahl von finger- bzw. stegartigen Stößeln 20. Je einer dieser im Querschnitt rechteckigen, als Flachprofil ausgebildeten Stößel 20 tritt von der rückwärtigen Seite her (rechts in Fig. 2) in einen Schacht 12 ein und schiebt eine seiner Konstruktionshöhe entsprechende Anzahl von übereinander angeordneten Zigaretten 13 auf der gegenüberliegenden Seite aus. Eine das Magazin auf der Rückseite begrenzende, aufrechte Rückwand 21 ist im Bereich der hin- und hergehenden Bewegungen des Schiebers 19 bzw. der Stößel 20 mit einer entsprechenden Eintrittsausnehmung 22 versehen. Eine Austrittsöffnung 23 im Bereich einer ggegenüberliegenden Vorderwand 24 führt in einen an die Tragplatte 17 bzw. 18 und an die Vorderwand 24 anschließenden horizontalen Zigarettenschacht 25, indem die nunmehr gebildete Zigaretten-Gruppe einem Weiterförderer zugeführt wird.For the ejection of a corresponding number of cigarettes 13 per shaft 12, a slide 19 is provided with a number of finger-like or web-like tappets 20 corresponding to the number of shafts 12 to be emptied. Each of these tappets 20, which are rectangular in cross section and designed as a flat profile, enters from the rear side (on the right in FIG. 2) into a shaft 12 and pushes out a number of cigarettes 13 arranged one above the other on the opposite side, corresponding to its construction height. An upright rear wall 21 delimiting the magazine on the back is provided with a corresponding entry recess 22 in the area of the reciprocating movements of the slide 19 or the plunger 20. An outlet opening 23 in the area of an opposite front wall 24 leads into a horizontal cigarette shaft 25 adjoining the support plate 17 or 18 and the front wall 24, in that the group of cigarettes now formed is fed to a further conveyor.

Der Schieber 19 bzw. dessen Stößel 20 werden nach dem Ausschub einer Zigaretten-Gruppe aus . den Schächten 12 in eine Ausgangsstellung zurückbewegt, in der die Stößel 20 vollständig aus den Schächten 12 zurückgezogen sind (Fig. 4). Die über den ausgeschobenen Zigaretten lagernden weiteren Zigaretten können nunmehr infolge ihres Eigengewichts in den Schächten 12 nach unten nachfallen. Dabei muß - unter zwischenzeitlicher Schräglage der Zigaretten während der Rückbewegung der Stößel 20 - eine Fallhöhe überwunden werden, die derjenigen der ausgeschobenen (drei) Zigaretten bzw. der Konstruktionshöhe der Stößel 20 entspricht. Um während dieser Abwärtsbewegung unerwünschte Schräglagen und dadurch verursachte Klemmstellungen der Zigaretten 13 zu vermeiden, ist benachbart zur Austrittsöffnung 23, also auf der zu den Enden der aus den Schächten 12 zurückgezogenen Stößel 20 gegenüberliegenden Seite ein bewegbares Stützorgan in Gestalt einer Tragstange 26 angeordnet. Diese ist beim vorliegenden Ausführungsbeispiel auf- und abbewegbar, nämlich aus einer unteren, zurückgezogenen Stellung gemäß Fig. 2 in die obere Stützstellung gemäß Fig. 3 und 4. In der letzteren befindet sich die Tragstange 26 etwa in halber Höhe des Fallweges der Zigaretten.The slide 19 and its plunger 20 are after a group of cigarettes. the shafts 12 moved back into a starting position in which the plunger 20 are completely withdrawn from the shafts 12 (Fig. 4). The further cigarettes stored above the ejected cigarettes can now fall downwards in the shafts 12 due to their own weight. It must be overcome - with the cigarette in the meantime inclined during the return movement of the plunger 20 - a drop height which corresponds to that of the ejected (three) cigarettes or the construction height of the plunger 20. In order to avoid undesired oblique positions and the resulting clamping positions of the cigarettes 13 during this downward movement, a movable support element in the form of a support rod 26 is arranged adjacent to the outlet opening 23, that is to say on the side opposite the ends of the plunger 20 withdrawn from the shafts 12. In the present exemplary embodiment, this can be moved up and down, namely from a lower, retracted position according to FIG. 2 into the upper supporting position according to FIGS. 3 and 4. In the latter, the carrying rod 26 is approximately half the height of the way the cigarettes fall.

Die Tragstange 26 wird während der Rückwärtsbewegung der Stößel 20 in die vorgenannte Stützposition gemäß Fig. 3 und 4 bewegt. Die von dem zurücklaufenden Stößel abliegenden Enden der Zigaretten 13 können sich dadurch auf die Tragstange 26 auflegen, nachdem eine Schwenkbewegung etwa in der halben Höhe des gesamten Fallweges von den Zigaretten ausgeführt worden ist (Fig. 3). Die gegenüberliegenden Endbereiche der Zigaretten 13 stützen sich während dieser Phase noch auf dem sich in der Rückbewegung befindenden Stößel 20 ab. Sobald dieser den Schacht 12 verläßt, werden die dieser Seite (Rückwand 21) zugekehrten Enden der Zigaretten 13 unter ihrem Eigengewicht bis zur Auflage auf der Tragplatte 17 bzw. 18 bewegt unter Ausführung einer Schwenkbewegung infolge Abstützung der gegenüberliegenden Enden auf der Tragstange 26 (Fig. 4). Wenn die Zigaretten diese Lage erreicht haben, wird die Tragstange 26 in die untere Ausgangsposition gemäß Fig. 2 abgesenkt. Die auf der Tragstange aufliegenden Bereiche der Zigaretten werden dabei ebenfalls abwärtsbewegt bis zur vollständigen Auflage auf den Tragplatten 17,18. Nunmehr haben die Zigaretten eine ordnungsgemäße untere Endlage erreicht und können in der beschriebenen Wiese in Gruppen ausgestoßen werden.The support rod 26 is moved during the backward movement of the plunger 20 into the aforementioned support position according to FIGS. 3 and 4. The ends of the cigarettes 13 lying away from the returning tappet can thereby rest on the support rod 26 after the cigarettes have carried out a pivoting movement approximately half the height of the entire fall path (FIG. 3). The opposite end regions of the cigarettes 13 are still supported on the plunger 20 which is in the return movement during this phase. As soon as the latter leaves the shaft 12, the ends of the cigarettes 13 facing this side (rear wall 21) are moved under their own weight until they rest on the support plate 17 or 18 while carrying out a pivoting movement as a result of supporting the opposite ends on the support rod 26 (FIG. 4). When the cigarettes have reached this position, the support rod 26 is lowered into the lower starting position according to FIG. 2. The areas of the cigarettes lying on the support rod are likewise moved downwards until they rest completely on the support plates 17, 18. The cigarettes have now reached a proper lower end position and can be ejected in groups in the meadow described.

Die Tragplatten 17, 18 sind auf der der Austrittsöffnung 23 zugekehrten Seite mit einer durchgehenden, langgestreckten Öffnung 27 versehen, in die die Tragstange 26 in der unteren Position absenkt ist. Zur Durchführung der Bewegungen der Tragstange 26 sind die Schachtwände 14 in diesem Bereich mit einer der Austrittsöffnung 23 zugekehrten Ausnehmung 29 versehen.The support plates 17, 18 are provided on the side facing the outlet opening 23 with a continuous, elongated opening 27 into which the support rod 26 is lowered in the lower position. To carry out the movements of the support rod 26, the shaft walls 14 are provided in this area with a recess 29 facing the outlet opening 23.

Bei dem vorliegenden Ausführungsbeispiel ist jeder Gruppe 15, 16 von Schächten 12 eine gesonderte Tragstange 26 zugeordnet. Die beiden Tragstangen sind über ein Parallelogrammgestänge mit den Parallellenkern 28 und 29 sowie einer von diesen auf- und abbewegbaren Traglasche 30 in dem beschriebenen Sinne angetrieben. Eine Schubstange 31 ist mit dem Parallelogrammgestänge (Parallellenker 29) verbunden und wird von einer zentralen Antriebswelle 32 hin- und hergehend angetrieben. Die Antriebswelle 32 ihrerseits wird durch einen Kurbeltrieb 33 bewegt.In the present exemplary embodiment, each group 15, 16 of shafts 12 is assigned a separate support rod 26. The two support rods are driven via a parallelogram linkage with the parallel core 28 and 29 and a support bracket 30 which can be moved up and down in the manner described. A push rod 31 is connected to the parallelogram linkage (parallel link 29) and is driven to and fro by a central drive shaft 32. The drive shaft 32 in turn is moved by a crank mechanism 33.

Eine weitere Einrichtung zur Gewährleistung der ordnungsgemäßen Abwärtsbewegung der Zigaretten 13 in den Schächten 12 besteht aus jedem Schacht 12 zugeordneten Tastfahnen 34. Es handelt sich dabei um dünnwandige Flachmaterialteile, über Schlitze 35 in der Vorderwand 24 in die Schächte 12 hineinragen. Die Tastfahnen 34 sind außerhalb der Schächte auf einer gemeinsamen, quergerichteten Haltestange 36 schwenkbar gelagert. Die Tastfahnen 34 sind so gestaltet bzw. derart außermittig in bezug auf die Haltestange 36 angeordnet, daß bei fehlenden Zigaretten in einem der Schächte 12 die betreffende Tastfahne unter Eigengewicht verschwenkt wird, derart, daß eine Nase 37 der Tastfahne 34 in den betreffenden Schacht 12 eintritt (strichpunktierte Linie in Fig. 2). Dadurch ergibt sich eine Veränderung der Relativstellung der betreffenden Tastfahne 34 in bezug auf eine quergerichtete Lichtschranke 38. Diese wird unterbrochen. Ein Fehlersignal wird ausgelöst.A further device for ensuring the proper downward movement of the cigarettes 13 in the shafts 12 consists of sensor tabs 34 assigned to each shaft 12. These are thin-walled flat material parts, protruding into the shafts 12 via slots 35 in the front wall 24. The tactile flags 34 are pivotally mounted outside of the shafts on a common, transverse support rod 36. The tactile flags 34 are designed or arranged eccentrically with respect to the holding rod 36 that, in the absence of cigarettes in one of the wells 12, the relevant tactile flag is pivoted under its own weight such that a nose 37 of the tactile flag 34 enters the relevant well 12 (dash-dotted line in Fig. 2). This results in a change in the relative position of the relevant touch flag 34 with respect to a transverse light barrier 38. This is interrupted. An error signal is triggered.

Damit die Tastfahne 34 bzw. die Nase 37 nicht allzuweit (tief) in den Schacht 12 eintritt, ist die Bewegungsamplitude der Tastfahne 34 begrenzt, und zwar durch eine für alle Tastfahnen gemeinsame, quergerichtete Anschlagstange 39. Diese tritt durch ein (kreisförmiges) Loch 40 in den Tastfahnen hindurch. Der Rand des Loches 40 erhält Anlage an der Anschlagstange 39, sobald die Tastfahne infolge Fehlens von Zigaretten in den betreffenden Schacht 12 eintritt. Sobald der Fehler beseitigt und der betreffende Schacht mit einer ununterbrochenen Folge von Zigaretten versehen ist, wird die Tastfahne infolge der nachgeförderten Zigaretten selbsttätig in die Ausgangsstellung (ausgezogene Linie in Fig. 2) zurückgeschwenkt. Die Nase 37 liegt in dieser störungsfreien Position an den zugekehrten Stirnenden der Zigaretten in dem Schacht an.So that the touch flag 34 or the nose 37 does not enter the shaft 12 too far (deep), the is Movement amplitude of the feeler flag 34 is limited, namely by a transverse stop rod 39 common to all feeler flags. This passes through a (circular) hole 40 in the feeler flags. The edge of the hole 40 is in contact with the stop rod 39 as soon as the touch flag enters the relevant shaft 12 due to the lack of cigarettes. As soon as the error has been eliminated and the shaft in question has been provided with an uninterrupted sequence of cigarettes, the touch flag is automatically pivoted back into the starting position (solid line in FIG. 2) as a result of the cigarettes being conveyed. In this trouble-free position, the nose 37 bears against the facing ends of the cigarettes in the shaft.

Eine weitere Einrichtung für den ordnungsgemäßen Transport der Zigaretten in den Schächten 12 bezieht sich auf den Einlauf der Zigaretten in diese. Wie aus Fig. 1 ersichtlich, sind die Schachtwände 14 keilförmig ausgebildet, nach oben hin breiter werdend. Auf den oberen Enden der so ausgebildeten Schachtwände 14 sind hin- und herdrehend angetriebene Verteilerorgane in Gestalt von langgestreckten, annäherend zylindrischen Rüttelstäben 41 angebracht. Diese sind an einem Ende mit einer Verlängerung 42 durch die Vorderwand 24 des Magazins hindurchgeführt und außerhalb desselben drehbar gelagert. Auf den Verlängerungen 42 sind jeweils Ritzel 43 gebildet, die mit einer für alle Rüttelstäbe 41 gemeinsamen Zahnstange 44 kämmen. Durch hin- und hergehende Bewegung der Zahnstange 44 werden die Rüttelstäbe 41 in Drehung mit wechselnder Richtung versetzt. Das vorstehend beschriebene Getriebe ist in einem langgestreckten Getriebegehäuse 45 an der Außenseite der Vorderwand 24 untergebracht.Another device for the proper transportation of the cigarettes in the chutes 12 relates to the entry of the cigarettes into them. As can be seen from Fig. 1, the shaft walls 14 are wedge-shaped, widening towards the top. On the upper ends of the shaft walls 14 formed in this way, rotatably driven distributor members in the form of elongated, approximately cylindrical vibrating rods 41 are attached. These are guided at one end with an extension 42 through the front wall 24 of the magazine and rotatably mounted outside of the same. On the extensions 42 each pinion 43 are formed, which mesh with a common rack 44 for all vibrating bars 41. By moving the rack 44 back and forth, the vibrating bars 41 are set in rotation with an alternating direction. The transmission described above is housed in an elongated transmission housing 45 on the outside of the front wall 24.

Die Rüttelstäbe 41 innerhalb des Magazins, nämlich am Eintrittsende der Schächte 12, sind in besonderer Weise ausgebildet. Am Außenumfang befinden sich in Längsrichtung verlaufende Erhöhungen und Vertiefungen in Gestalt von Riefen 46. Diese sind bei den vorliegenden Rüttelstäben 41 nur in einem mittleren Bereich gebildet. An den Enden der Rüttelstäbe - bei dem vorliegenden Ausführungsbeispiel an beiden Enden - sind Querschnittsverjüngungen 47 und 48 gebildet. Diese konisch auslaufenden Enden der Rüttelstäbe 46 bewirken, daß die Endbereiche der Zigaretten 13 durch die Rüttelstäbe nicht mechanisch beansprucht werden und demzufolge keine Feintabakteile aus den Zigaretten herausgedrückt werden. Die Gestaltung der Rüttelstäbe 41 im vorsstehenden Sinne hat demnach zur Folge, daß der Austritt von Tabak an den Enden der Zigaretten infolge der Rüttelbewegungen vermieden wird. Wenn Zigaretten mit einem Filter verarbeitet werden, ist es ausreichend, wenn eine querschnittsverjüngung lediglich an einem Ende - an dem von dem Zigarettenfilter abliegenden - gebildet ist.The vibrating bars 41 within the magazine, namely at the entry end of the shafts 12, are designed in a special way. On the outer circumference there are elevations and depressions running in the longitudinal direction in the form of grooves 46. These are formed in the present vibrating bars 41 only in a central region. At the ends of the vibrating bars - in the present embodiment at both ends - cross-sectional tapering 47 and 48 are formed. These conically tapering ends of the vibrating bars 46 ensure that the end areas of the cigarettes 13 are not mechanically stressed by the vibrating bars and consequently no fine tobacco parts are pressed out of the cigarettes. The design of the vibrating rods 41 in the above sense therefore has the consequence that tobacco leakage at the ends of the cigarettes is avoided as a result of the vibrating movements. If cigarettes are processed with a filter, it is sufficient if a cross-sectional taper is formed only at one end - at the end remote from the cigarette filter.

Die einzelnen Einrichtungen zur Gewährleistung eines störungsfreien Zigarettenflusses innerhalb der Schächte 12, also die Tragstange 26, die Tastfahnen 34 und die Rüttelstäbe 41, können auch unabhängig voneinander eingesetzt werden.The individual devices for ensuring a trouble-free flow of cigarettes within the chutes 12, that is to say the support rod 26, the feeler tabs 34 and the vibrating bars 41, can also be used independently of one another.
