Abstract

The cigarettes (2) or similar tobacco product are prevented from moving backwards from a second position (3) consisting of a container compartment of a belt (12) of a packaging machine, to the first position by use of blocking pieces (21). The first position is constituted by the ejector position at the base of one cigarette magazine (39) of the packaging machine. The track (11) of the layer of cigarettes (7) between the first and second positions runs through an orifice (17). In the second position, the track is defined by a stop piece (16). At least part of the track is defined by a lower (18) and upper (19) guide surface at least one of which has a step (21) enlarging the distance between the guide surfaces.

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 zweite Position.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 second position.

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 be.

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

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. Moderne Packmaschinen arbeiten mit hohen Stößelgeschwindigkeiten, die den Zigaretten bei ihrer längs-axialen 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 zurück-geworfen 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 layered from magazines in receiving chambers one mostly moved step by step Chamber belt transferred. The cigarette layers become one at the bottom Number of shafts arranged side by side and below a magazine, in where the cigarettes lie on top of each other, formed and pushed out by a slide, with each shaft supplying a cigarette for the location. The cigarette layers are then inserted into a receptacle, e.g. in form of a cyclically movable chamber, in which they are usually transversely aligned axially further packaging operations. Modern packaging machines work at high ram speeds, which the cigarettes at their longitudinal-axial Give movement high speeds. The high clock speeds require that the speed of the slider before reaching the front Reversal point is already reduced so that the slide to release the first Position can be withdrawn quickly. The cigarette layer follows this speed reduction of the slide does not, but hurries as a result their sluggishness ahead of the slide. Bounce at the end of this axial movement the cigarettes in the second position usually against an end stop, from which they are thrown back a little towards the first position due to elastic forces will. The position of the cigarettes in the second position is therefore very great undefined. It can happen that some cigarettes have a cigarette pack are thrown back so far that they protrude into the trajectory Ends hinder the subsequent cross transport. This can damage it the ends of the cigarettes or even to tear off the ends at that end Lead filter.

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 in a second position, which in the case shown by a standby 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 common in a conventional packaging machine gradually movable in the direction of arrow 14, so that in three successive Steps and conveyor positions successively three cigarette layers into the chamber 3 are pushed in. The movement path 11 of the cigarette layer in the direction of the arrow 9 is limited by an axial stop 16, which in the case shown is not 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 of the upper guide surface 19 to lower guide surface 18 enlarged. The end face 22 of this step runs perpendicular to the cigarette axes and to the direction of movement 9 and acts as Locking means, a rebound of the cigarettes thrown into the chamber 3 prevented. 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 Movement direction 14 of the chamber conveyor 12 extended by the from To give chamber 3 protruding cigarette ends a safe guide.

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 Arrow 9 shows a cigarette layer 7 from its first position below the chutes 4 transferred via the movement path 11 into the chamber 3 of the chamber conveyor 12. During this transfer, the guide surfaces 18 and 19 exercise by friction a braking force on the cigarettes because their distance from each other is just the same which is or 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 of cigarettes very large in modern high-performance machines , individual or all cigarettes can bounce off the stop 16 and themselves move back a little against the conveying direction 9. Get their ends back into the area of the mouthpiece 17, so they are in the following Further movement of the chamber 3 in the conveying direction 14 is damaged or even destroyed. This is prevented by the step 21 provided according to the invention. The cigarettes rebounding from the stop surface 16 bump against the end face 22 of level 21 and thereby move back into the mouthpiece 17 hindered. The end face 22 of the step 21 thus acts as a blocking means to protect against damage or destruction of the cigarettes. While The subsequent movement of the chamber 3 in the conveying direction 14 becomes 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 step 21 in the upper guide surface is the backward movement of such a cigarette end but limited, so that even in this case interference be avoided in the transfer station. The one in chamber 3 deformed block located can be discovered and located in a downstream station be removed.

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 eingestoßenen 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 with the same reference numerals provided as in Figures 1 and 2.

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 the lower guide surface narrowing sliding surface 36 and a perpendicular to it, transversely stop surface 37 extending to the direction of movement of the cigarettes. The the Movement path 11 forward in the direction of arrow 9 passing cigarettes of the cigarette layer 7 urge the spring plate 34 against the upper guide surface 19. Have the cigarettes reached their end position in the receiving chamber 3, like that 4, 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.
