Description

Die Erfindung betrifft eine Vorrichtung zum Überführen einer Lage von Zigaretten oder ähnlichen stabförmigen Artikeln der tabakverarbeitenden Industrie mittels eines Schiebers in Richtung der Zigarettenachsen aus einer ersten Position entlang einer Bewegungsbahn in eine in einer zweiten Position befindliche Kammer mit einer die Bewegungsbahn begrenzenden Anschlag.The invention relates to a device for transferring a layer of cigarettes or similar rod-shaped articles of the tobacco processing industry by means of a Slide in the direction of the cigarette axes from a first position a trajectory in a chamber in a second position with a the stop limiting the movement path.

Als Zigarettenlage wird im allgemeinen eine Gruppe aus mehreren parallel nebeneinander liegenden Zigaretten bezeichnet. In Bezug auf die vorliegende Erfindung sollen allerdings auch einzelne Zigaretten, die mit einem Schieber axial aus einer ersten Position in eine zweite Position überführt werden, von dem Begriff umfaßt sein.A group of several in parallel next to each other is generally used as the cigarette layer called lying cigarettes. In relation to the present invention However, individual cigarettes, which are slid axially out of a are transferred from the first position to a second position his.

Als stabförmige Artikel der tabakverarbeitenden Industrie werden im vorliegenden Zusammenhang außer Zigaretten auch Zigarillos, Stumpen, Zigarren oder andere rauchbare stabförmige Artikel aus Tabak, Tabakersatzstoffen oder aus Mischungen beider angesehen. Auch sogenannte "rauchlose" Zigaretten sind von dem Begriff umfaßt.As rod-shaped articles of the tobacco processing industry are in the present Context besides cigarettes, also cigarillos, pillars, cigars or others smokable rod-shaped articles made of tobacco, tobacco substitutes or mixtures viewed both. So-called "smokeless" cigarettes are also part of the term includes.

Das lagenweise Überführen von Zigaretten aus einer ersten Position in eine zweite Position ist besonders in Packmaschinen aktuell. Dort werden die Zigaretten lagenweise aus Magazinen in Aufnahmekammern eines meist schrittweise bewegten Kammernbandes überführt. Die Zigarettenlagen werden am unteren Ende einer Anzahl nebeneinander und unterhalb eines Magazins angeordneter Schächte, in denen die Zigaretten übereinanderliegen, gebildet und von einem Schieber ausgeschoben, wobei jeder Schacht eine Zigarette für die Lage liefert. Die Zigarettenlagen werden von dem Schieber dann in eine Aufnahme, z.B. in Form einer taktweise bewegbaren Kammer, überführt, in der sie in der Regel queraxial zu weiteren Verpackungsoperationen abgefördert werden.
Durch die US 2 551 199 ist eine Vorrichtung zum Überführen von Zigarettenreihen in Zigarettenschachteln bekannt geworden, bei der Zigaretten einer Zigarettenreihe axial zunächst auf einem Boden aus den Endschächten eines Packmaschinenmagazins entfernt und in Richtung auf eine Zigarettenschachtel bewegt werden. Vor Erreichen der Schachtel, also auf dem Weg zwischen dieser und den Schächten des Magazins, wird der Boden zu dem Magazin zurückbewegt, um eine weitere Zigarettenreihe auszutragen. Zur Vermeidung einer Mitnahme der auf einer Muldenplatte zwischenabgelegten Zigaretten in Richtung auf das Magazin werden Abstreifer aktiviert, die die Zigaretten relativ zu der zurückbewegten Bodenplatte zurückhalten und so eine unerwünschte Mitnahme verhindern. In einem zweiten Schritt wird die Zigarettenreihe dann in die Zigarettenschachtel verbracht.
Durch die DE 39 18 236 ist eine Vorrichtung zum Überführen von Zigaretten in eine Aufnahme bekannt geworden, bei der Zigaretten einer Reihe axial von einem Schieber aus Schächten eines Magazins entfernt und über eine Muldenanordnung in die Aufnahme geschoben werden. Zwecks Vermeidung von unkrollierten Bewegungen der Zigaretten relativ zu dem Schieber wird auf die Zigaretten während der Überführung eine Bremskraft ausgeübt, die durch Saugluft in den Mulden oder durch auf die Mulden gerichtete Blasluft erzeugt wird.
Moderne Packmaschinen arbeiten mit hohen Stößelgeschwindigkeiten, die den Zigaretten bei ihrer längsaxialen Bewegung hohe Geschwindigkeiten verleihen. Die hohen Taktraten erfordern, daß die Geschwindigkeit des Schiebers vor dem Erreichen des vorderen Umkehrpunktes bereits reduziert wird, damit der Schieber zur Freigabe der ersten Position schnell wieder zurückgezogen werden kann. Die Zigarettenlage folgt dieser Geschwindigkeitsreduzierung des Schiebers nicht, sondern sie eilt infolge ihrer Massenträgheit dem Schieber voraus. Am Ende dieser Axialbewegung prallen die Zigaretten in der zweiten Position gewöhnlich gegen einen Endanschlag, von dem sie infolge elastischer Kräfte ein Stück in Richtung zur ersten Position zurückgeworfen werden. Die Lage der Zigaretten in der zweiten Position ist daher sehr undefiniert. Dabei kann es geschehen, daß einige Zigaretten einer Zigarettenlage soweit zurückgeworfen werden, daß ihre in die Bewegungsbahn hineinragenden Enden den anschließenden Quertrans-port behindern. Das kann zur Beschädigung der Zigarettenenden oder sogar zum Abreißen der an diesem Ende befindlichen Filter führen.The layer-by-layer transfer of cigarettes from a first position to a second position is particularly relevant in packaging machines. There, the cigarettes are transferred in layers from magazines into receiving chambers of a chamber belt that is usually moved step by step. The cigarette layers are formed at the lower end of a number of shafts arranged side by side and below a magazine, in which the cigarettes lie one above the other, and are pushed out by a slide, each shaft supplying a cigarette for the layer. The slide then transfers the cigarette layers into a receptacle, for example in the form of a chamber which can be moved in cycles, in which they are generally conveyed transversely axially to further packaging operations.
A device for transferring rows of cigarettes into cigarette boxes has become known from US 2,551,199, in which cigarettes of a row of cigarettes are first axially removed from the end shafts of a packaging machine magazine on a floor and moved in the direction of a cigarette box. Before the box is reached, i.e. on the way between it and the magazine chutes, the bottom is moved back to the magazine in order to discharge another row of cigarettes. To prevent entrainment of the cigarettes placed on a trough plate in the direction of the magazine, wipers are activated which hold the cigarettes back relative to the base plate moved back and thus prevent undesired entrainment. In a second step, the row of cigarettes is then placed in the cigarette box.
From DE 39 18 236 a device for transferring cigarettes into a receptacle has become known, in which cigarettes of a row are axially removed from a magazine by a slide and pushed into the receptacle via a trough arrangement. In order to avoid unrolled movements of the cigarettes relative to the slide, a braking force is exerted on the cigarettes during the transfer, which is generated by suction air in the troughs or by blowing air directed onto the troughs.
Modern packaging machines work with high tappet speeds, which give the cigarettes high speeds when they move axially. The high clock rates require that the speed of the slide is reduced before the front reversal point is reached, so that the slide can be pulled back quickly to release the first position. The cigarette layer does not follow this reduction in the speed of the slide, but rather rushes ahead of the slide due to its inertia. At the end of this axial movement, the cigarettes in the second position usually hit an end stop, from which they are thrown back a little towards the first position due to elastic forces. The position of the cigarettes in the second position is therefore very undefined. It can happen that some cigarettes of a cigarette layer are thrown back so far that their ends protruding into the path of movement hinder the subsequent transverse transport. This can damage the cigarette ends or even tear off the filters located at that end.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, die Endlagen von in ihre zweiten Positionen überführten Zigaretten zu kontrollieren.
Gelöst wird diese Aufgabe erfindungsgemäß dadurch, daß Sperrmittel (21, 24, 34, 32) zum Verhindern einer Rückwärtsbewegung der Zigaretten (2) von dem Anschlag (16) zur ersten Position hin vorgesehen sind.
Fortführungen, Weiterbildungen und vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben. Dabei beziehen sich die Ansprüche 2 bis 5 auf die Ausgestaltung der Vorrichtung in einer Packmaschine zum Verpacken von Zigaretten. Die Ansprüche 6 bis 8 enthalten Merkmale einer ersten Ausführungsform des Sperrmittels, das die Rückwärtsbewegung der Zigaretten aus der zweiten Position verhindert. Die Ansprüche 9 und 10 betreffen zwei weitere Ausführungen des Sperrmittels.
Die Erfindung bietet den Vorteil, daß sie das Zurückprallen von Zigaretten beim Einstoßen in eine Aufnahmekammer eines Kammernbandes in einer Packmaschine zuverlässig verhindert, so daß Störungen im Betrieb der Packmaschine vermieden werden. Die Gefahr der Beschädigung oder Zerstörung von Zigaretten infolge von unkontrollierten Rückbewegungen ist weitgehend ausgeschaltet. Dabei ist gleichzeitig eine sichere Führung der Zigaretten beim anschließenden Quertransport in die nächste Einstoßposition gewährleistet. The present invention has for its object to control the end positions of cigarettes transferred to their second positions.
This object is achieved according to the invention in that locking means (21, 24, 34, 32) are provided to prevent the cigarettes (2) from moving backwards from the stop (16) to the first position.
Continuations, further developments and advantageous refinements of the invention are specified in the subclaims. The claims 2 to 5 relate to the design of the device in a packaging machine for packing cigarettes. Claims 6 to 8 contain features of a first embodiment of the locking means which prevents the cigarettes from moving backwards from the second position. Claims 9 and 10 relate to two further versions of the locking means.
The invention offers the advantage that it reliably prevents the rebounding of cigarettes when they are pushed into a receiving chamber of a chamber band in a packaging machine, so that malfunctions in the operation of the packaging machine are avoided. The risk of damage or destruction of cigarettes as a result of uncontrolled back movements is largely eliminated. At the same time, a safe guidance of the cigarettes during the subsequent transverse transport into the next insertion position is guaranteed.

In Figur 1 ist ein Ausführungsbeispiel der erfindungsgemäß vorgeschlagenen Vorrichtung in einer perspektivischen Ansicht schematisch dargestellt. Figur 1 zeigt eine Überführungsvorrichtung 1, mit der Zigaretten 2 zur Bildung von Zigarettenblöcken lagenweise in Aufnahmekammern 3 überführt werden. Die Zigaretten 2 sind in Schächten 4, die jeweils durch Wände 6 begrenzt werden, übereinander angeordnet. Die Schächte 4 befinden sich im unteren Teil eines in der Zeichnung nicht weiter dargestellten bekannten Magazins 39, aus dem die Zigaretten in die Schächte 4 absinken. Am unteren Ende der Schächte bilden die Zigaretten eine Lage 7, die im dargestellten Fall aus 7 nebeneinanderliegenden Zigaretten besteht. Aus dieser ersten Position, die auch als Bereitstellungsposition bezeichnet wird, bewegt ein Schieber 8 die Zigarettenlage in Pfeilrichtung 9 entlang einer Bewegungsbahn 11 in eine zweite Position, welche im dargestellten Fall durch eine bereitstehende Aufnahmekammer 3 definiert ist. Die Kammer 3 ist Teil eines Kammerförderers 12, von dem nur ein Teil des Förderbandes 13 angedeutet ist. Der Kammerförderer 12 ist in einer herkömmlichen Packmaschine gewöhnlich schrittweise in Pfeilrichtung 14 bewegbar, so daß in drei aufeinanderfolgenden Schritten und Fördererpositionen nacheinander drei Zigarettenlagen in die Kammer 3 eingestoßen werden. Die Bewegungsbahn 11 der Zigarettenlage in Pfeilrichtung 9 ist durch einen axialen Anschlag 16 begrenzt, der im dargestellten Fall auf nicht gezeigte Weise am Maschinengestell stationär angeordnet ist.FIG. 1 shows an embodiment of the device proposed according to the invention shown schematically in a perspective view. Figure 1 shows a transfer device 1, with the cigarettes 2 to form cigarette blocks to be transferred in layers in receiving chambers 3. The cigarettes 2 are in shafts 4, each delimited by walls 6, one above the other arranged. The shafts 4 are located in the lower part of one in the drawing not shown known magazine 39 from which the cigarettes in the Shafts 4 sink. At the bottom of the shafts, the cigarettes form one Layer 7, which in the case shown consists of 7 adjacent cigarettes. From this first position, which is also referred to as the provision position, a slide 8 moves the cigarette layer in the direction of arrow 9 along a movement path 11 into a second position, which in the illustrated case is represented by a ready position Receiving chamber 3 is defined. The chamber 3 is part of a chamber conveyor 12, of which only a part of the conveyor belt 13 is indicated. The chamber conveyor 12 is usually incremental in a conventional packaging machine Movable in the direction of arrow 14, so that in three successive steps and Conveyor positions pushed three layers of cigarette into the chamber 3 in succession become. The path of movement 11 of the cigarette layer in the direction of arrow 9 is through limits an axial stop 16, which is not shown in the case shown Way is arranged stationary on the machine frame.

Die Bewegungsbahn 11 ist durch ein Mundstück 17 geführt, das eine geordnete Bewegung der Zigarettenlage 7 durch die Bewegungsbahn gewährleistet. Dieses Mundstück 17 weist eine untere Führungsfläche 18 und eine obere Führungsfläche 19 auf. Der Abstand der Führungsflächen 18 und 19 voneinander ist gleich oder vorzugsweise geringfügig kleiner als der Durchmesser der in den Zigarettenlagen 7 befindlichen Zigaretten. Dadurch wird erreicht, daß die Zigaretten der Zigarettenlage 7 während ihrer Bewegung entlang der Bewegungsbahn 11 durch die Reibung zwischen den Führungsflächen leicht abgebremst werden, so daß sie während ihrer Bewegung entlang der Bewegungsbahn 11 länger mit der vorderen Stoßfläche des Schiebers 8 in Kontakt bleiben.The movement path 11 is guided by a mouthpiece 17, which is an orderly one Movement of the cigarette layer 7 ensured by the trajectory. This Mouthpiece 17 has a lower guide surface 18 and an upper guide surface 19 on. The distance between the guide surfaces 18 and 19 is equal to or preferably slightly smaller than the diameter of the ones in the cigarette layers 7 cigarettes. This ensures that the cigarettes in the cigarette layer 7 during their movement along the movement path 11 due to the friction between the guide surfaces are braked slightly so that they during their Movement along the trajectory 11 longer with the front face of the Slider 8 stay in contact.

Zu ihrem stromabwärtigen Ende hin weist die obere Führungsfläche 19 eine querverlaufende Stufe 21 auf, die den Abstand der oberen Führungsfläche 19 zur unteren Führungsfläche 18 vergrößert. Die Stirnfläche 22 dieser Stufe verläuft senkrecht zu den Zigarettenachsen und zur Bewegungsrichtung 9 und wirkt als Sperrmittel, das ein Zurückprallen der in die Kammer 3 eingestoßenen Zigaretten verhindert. Die Stirnfläche 22 der Stufe 21 sowie der sich an die Stufe 22 in Bewegungsrichtung 9 anschließende Bereich 23 der oberen Führungsfläche 19 sind in Bewegungsrichtung 14 des Kammernförderers 12 verlängert, um den aus der Kammer 3 herausragenden Zigarettenenden eine sichere Führung zu geben.The upper guide surface 19 has a transverse end toward its downstream end Level 21 on the distance between the upper guide surface 19 to the lower Guide surface 18 enlarged. The end face 22 of this step runs vertically to the cigarette axes and the direction of movement 9 and acts as a blocking means, which prevents the cigarettes which have been pushed into the chamber 3 from rebounding. The end face 22 of the step 21 and of the step 22 in the direction of movement 9 adjoining area 23 of the upper guide surface 19 are in the direction of movement 14 of the chamber conveyor 12 extended by the from the chamber 3 to give excellent guidance to outstanding cigarette ends.

Figur 5 zeigt die Anordnung der Figur 1 in einem Querschnitt, bei dem sich der Schieber 8 in seiner vorderen Umkehrposition befindet, nachdem er eine Zigarettenlage 7 in die Aufnahme 3 ausgestoßen hat.Figure 5 shows the arrangement of Figure 1 in a cross section in which the Slider 8 is in its forward reverse position after having a cigarette pack 7 has ejected into the receptacle 3.

Im Betrieb wird bei jedem Überführungshub des Schiebers 8 in Richtung des Pfeiles 9 eine Zigarettenlage 7 aus ihrer ersten Position unterhalb der Schächte 4 über die Bewegungsbahn 11 in die Kammer 3 des Kammerförderers 12 überführt. Während dieser Überführung üben die Führungsflächen 18 und 19 durch Reibung eine Bremskraft auf die Zigaretten aus, weil ihr Abstand voneinander gerade gleich dem oder geringfügig kleiner als der Zigarettendurchmesser ist. Gerade bei großen Schiebergeschwindigkeiten wird dadurch der Kontakt des Schiebers zu den Zigarettenenden verbessert, so daß diese über einen weiten Abschnitt der Bewegungsbahn 11 keine unkontrollierten Bewegungen ausführen können, die zu Störungen führen könnten. Vielmehr ist durch die Bremskraft der Führungsflächen 18 und 19 die Anlage der Zigaretten 2 an dem Schieber 8 weitgehend gewährleistet. Erst wenn der Schieber sich seiner vorderen Umkehrposition nähert, die in Figur 5 zu erkennen ist, wird seine Geschwindigkeit so reduziert, daß sich die angestoßenen Zigaretten von seiner Stoßfläche lösen und sich auf dem letzten Stück frei in die Kammer 3 und gegen den Anschlag 16 bewegen. Da die axiale Bewegungsgeschwindigkeit der Zigaretten bei modernen Hochleistungsmaschinen sehr groß ist, können einzelne oder alle Zigaretten von dem Anschlag 16 abprallen und sich ein Stück entgegen der Förderrichtung 9 zurückbewegen. Gelangen ihre Enden dabei in den Bereich des Mundstücks 17 zurück, so werden sie bei der folgenden Weiterbewegung der Kammer 3 in Förderrichtung 14 beschädigt oder sogar zerstört. Durch die gemäß der Erfindung vorgesehene Stufe 21 wird dies verhindert. Die von der Anschlagfläche 16 zurückprallenden Zigaretten stoßen gegen die Stirnfläche 22 der Stufe 21 und werden dadurch an einer Rückbewegung in das Mundstück 17 hinein gehindert. Die Stirnfläche 22 der Stufe 21 wirkt somit als Sperrmittel zum Schutz gegen Beschädigungen oder Zerstörungen der Zigaretten. Während der nachfolgenden Bewegung der Kammer 3 in Förderrichtung 14 werden die Zigarettenenden von dem vorderen Flächenabschnitt 23 der oberen Führungsfläche 19 und der Stirnfläche 22 der Stufe 21 zur benachbarten Einstoßstation sicher geführt.In operation, with each transfer stroke of the slide 8 in the direction of the arrow 9 a cigarette layer 7 from its first position below the shafts 4 the movement path 11 transferred into the chamber 3 of the chamber conveyor 12. While this transfer practice the guide surfaces 18 and 19 by friction Braking force on the cigarettes because their distance from each other is just the same or is slightly smaller than the cigarette diameter. Especially with big ones The speed of the slide becomes the contact of the slide with the cigarette ends improved so that this over a wide section of the trajectory 11 no uncontrolled movements can lead to disturbances could lead. Rather, the braking force of the guide surfaces 18 and 19 the installation of the cigarettes 2 on the slide 8 largely ensured. First when the slider approaches its forward reversing position, which increases in Figure 5 is recognized, its speed is reduced so that the initiated Detach cigarettes from its butt surface and freely slide into the last piece Move chamber 3 and against the stop 16. Because the axial movement speed the cigarettes are very large in modern high-performance machines, can bounce off individual or all cigarettes from the stop 16 and one Move the piece back against the conveying direction 9. Get their ends at it back in the area of the mouthpiece 17, so they are in the following further movement the chamber 3 in the conveying direction 14 damaged or even destroyed. This is prevented by the step 21 provided according to the invention. The of rebounding the stop surface 16 against the end face 22 the stage 21 and thereby move back into the mouthpiece 17th hindered in. The end face 22 of the stage 21 thus acts as a locking means Protection against damage or destruction of the cigarettes. During the subsequent movement of the chamber 3 in the conveying direction 14, the cigarette ends from the front surface section 23 of the upper guide surface 19 and the end face 22 of stage 21 to the neighboring push-in station.

Ist der Weg für eine ankommende Zigarettenlage in die Kammer 3 nicht frei, weil z.B. eine Zigarette einer vorher eingestoßenen Zigarettenlage sich quer gelegt hat, so wird die ankommende Zigarettenlage von dem Schieber 8 trotzdem eingestoßen und dabei infolge der Kraft des Schiebers 8 teilweise verformt. Die Enden solcher verformter Zigaretten haben die Tendenz, sich beim Nachlassen des Schieberdruckes zurückzubewegen. Durch die als Sperrmittel gegen solche Bewegungen wirkende Stufe 21 in der oberen Führungsfläche wird die Rückwärtsbewegung eines solchen Zigarettenendes aber begrenzt, so daß auch in diesem Fall Störungen in der Überführungsstation vermieden werden. Der in der Kammer 3 befindliche deformierte Block kann in einer stromab folgenden Station entdeckt und entfernt werden. The way for an incoming cigarette layer in the chamber 3 is not clear because e.g. a cigarette from a previously inserted layer of cigarettes has laid across, the incoming cigarette layer is nevertheless pushed in by the slide 8 and partially deformed due to the force of the slide 8. The ends of such Deformed cigarettes have a tendency to decrease in slide pressure to move back. By acting as a blocking agent against such movements Acting stage 21 in the upper guide surface is the backward movement of a such cigarette end but limited, so that even in this case interference be avoided in the transfer station. The one in chamber 3 deformed block can be discovered and removed in a downstream station become.

In den Figuren 1 und 2 ist als Sperrmittel gegen die Rückwärtsbewegung von in die Kammer 3 eingestoßenen Zigaretten eine in der oberen Führungsfläche 19 des Mundstücks 17 vorgesehene querverlaufende Stufe 21 vorgesehen. Die Figuren 2 und 3 zeigen eine zweite Ausführungsform eines Sperrmittels in zwei verschiedenen Arbeitspositionen. Gleiche Teile sind wieder mit denselben Bezugszeichen versehen wie in den Figuren 1 und 2. Als Sperrmittel gegen die Rückwärtsbewegung der in die Kammer 3 eingestoßenen Zigarettenlage 7 ist gemäß den Figuren 2 und 3 ein Riegel 24 vorgesehen. Dieser Riegel 24 ist etwa senkrecht zur Bewegungsrichtung 9 der Zigarettenlage 7 in die Bewegungsbahn 11 der Zigarettenlage bewegbar. Dazu ist er an einem Arm 26 eines Winkelhebels 27 angebracht, der mittels eines Betätigungselementes 28 gegen die Kraft einer Feder 29 um eine Achse 31 schwenkbar ist. Das Betätigungselement 28 wird von einem Antriebsorgan 32 angetrieben. Im Ruhezustand drückt die Feder 29 den Hebelarm 26 entgegen dem Uhrzeigersinn nach oben, so daß der Riegel 24 sich außerhalb der Bewegungsbahn der Zigarettenlage 7 befindet. Sobald die Zigarettenlage komplett in die Aufnahme 3 eingeschoben ist (vgl. Figur 3), bewegt der Antrieb 32 das Betätigungselement 28 in Pfeilrichtung 33 und schwenkt damit den Hebel 27 im Uhrzeigersinn um die Schwenkachse 31, wodurch der Riegel 24 gegen die Federkraft 29 in die Bewegungsbahn der Zigarettenlage 7 bewegt wird. Wird der Stößel 8 jetzt in seine Ausgangslage zurückgeführt, so werden die in die Kammer 3 einge-stoßenen Zigaretten der Zigarettenlage 7 durch den Riegel daran gehindert, ihm zu folgen.In Figures 1 and 2 is a blocking means against the backward movement from in Chamber 3 injected cigarettes in the upper guide surface 19 of the Mouthpiece 17 provided transverse stage 21 is provided. Figures 2 and Fig. 3 show a second embodiment of a locking means in two different Working positions. The same parts are again provided with the same reference numerals as in Figures 1 and 2. As a blocking means against the backward movement the cigarette ply 7 pushed into the chamber 3 is according to FIGS 3 a latch 24 is provided. This bolt 24 is approximately perpendicular to the direction of movement 9 of the cigarette layer 7 can be moved into the movement path 11 of the cigarette layer. For this purpose, it is attached to an arm 26 of an angle lever 27, which means an actuating element 28 against the force of a spring 29 about an axis 31 is pivotable. The actuating element 28 is driven by a drive element 32 driven. In the idle state, the spring 29 presses the lever arm 26 against the Clockwise upwards, so that the latch 24 is outside the movement path the cigarette layer 7 is located. Once the cigarette ply completely in the intake 3 is inserted (see FIG. 3), the drive 32 moves the actuating element 28 in the direction of arrow 33 and thus pivots the lever 27 clockwise about the pivot axis 31, whereby the bolt 24 against the spring force 29 in the Movement path of the cigarette layer 7 is moved. The plunger 8 is now in its Starting position returned, the cigarettes pushed into the chamber 3 the cigarette layer 7 prevented by the bolt from following him.

Figur 4 zeigt eine weitere Ausführungsform des Sperrmittels nach der Erfindung. Hier besteht das Sperrmittel aus einem Federblech 34, das federnd zwischen der oberen und der unteren Führungsfläche 19 bzw. 18 angeordnet ist. Das Federblech 34 weist eine den Querschnitt des Durchlasses zwischen der oberen und der unteren Führungsfläche verengende Gleitfläche 36 und eine dazu senkrechte, quer zur Bewegungsrichtung der Zigaretten verlaufende Anschlagfläche 37 auf. Die die Bewegungsbahn 11 vorwärts in Pfeilrichtung 9 passierenden Zigaretten der Zigarettenlage 7 drängen das Federblech 34 gegen die obere Führungsfläche 19. Haben die Zigaretten ihre Endposition in der Aufnahmekammer 3 erreicht, wie das in Figur 4 gezeigt ist, so federt das Federblech 34 in die Bewegungsbahn 11 hinein, so daß seine Anschlagfläche 37 als Sperrmittel gegen das Zurückbewegen einer Zigarette wirkt.Figure 4 shows a further embodiment of the locking means according to the invention. Here, the locking means consists of a spring plate 34 which resiliently between the upper and lower guide surface 19 and 18 is arranged. The spring plate 34 has a cross section of the passage between the upper and lower ones Guide surface narrowing sliding surface 36 and a perpendicular thereto, transverse to Direction of movement of the cigarette extending stop surface 37. The the trajectory 11 forward in the direction of arrow 9 passing cigarettes of the cigarette position 7 push the spring plate 34 against the upper guide surface 19. Have the cigarettes reached their end position in the receiving chamber 3, as in FIG. 4 is shown, the spring plate 34 springs into the movement path 11, so that its stop surface 37 as a blocking means against moving back one Cigarette works.

Gemäß Figur 6 besteht das Sperrmittel gegen das Zurückbewegen einer in die Aufnahme 3 eingestoßenen Zigarette aus einer Stufe 38, die in der unteren Führungsfläche 18 der Bewegungsbahn 11 quer zur Bewegungsrichtung 9 der Zigarettenlage 7 verläuft. Die Wirkung dieser Stufe 38 entspricht ganz der Stufe 21, die im Zusammenhang mit den Figuren 1 und 5 beschrieben wurde.According to FIG. 6, there is the blocking means against moving one back into the receptacle 3 injected cigarette from a level 38 that is in the lower guide surface 18 of the movement path 11 transverse to the direction of movement 9 of the cigarette layer 7 runs. The effect of this level 38 corresponds entirely to level 21, which in In connection with Figures 1 and 5 has been described.
