Description

Die vorliegende Erfindung betrifft eine Vorrichtung zur Förderung von Produkten, vorzugsweise Zigarettenpackungen, in einer Fertigungs- und/oder Verpackungsanlage zur Herstellung und/oder Verpackung von Zigaretten oder anderen rauchbaren Artikeln, mit einer eine Antriebswelle aufweisenden Antriebseinheit, die über eine Getriebeeinrichtung ein das Produkt mindestens zeitweise kontaktierendes, eine Förderbewegung ausführendes Förderteil antreibt, insbesondere einen Hochheber, mit dem die Produkte förderbar, insbesondere anhebbar sind. Des Weiteren betrifft die vorliegende Erfindung eine Fertigungs- und/oder Verpackungsanlage zur Herstellung und/oder Verpackung von Zigaretten oder anderen rauchbaren Artikeln, in die die vorgenannte Fördervorrichtung integriert ist.The present invention relates to a device for conveying products, preferably cigarette packets, in a manufacturing and / or packaging plant for the manufacture and / or packaging of cigarettes or other smokable articles, with a drive unit having a drive shaft, the at least one product via a transmission device temporarily contacting, a conveying movement exporting conveyor part drives, in particular a high lift, with which the products are conveyed, in particular can be raised. Furthermore, the present invention relates to a manufacturing and / or packaging plant for the manufacture and / or packaging of cigarettes or other smokable articles, in which the aforementioned conveying device is integrated.

Derartige Fördervorrichtungen in Fertigungs- und/oder Verpackungsanlagen zur Herstellung und/oder Verpackung von Zigaretten oder dergleichen sind im Stand der Technik bekannt. Beispielsweise ist aus der DE 24 62 974 ein taktweise arbeitender Hubförderer mit einem Hochheber bekannt, der Zigarettenpackungen, die diesem horizontal zugefördert werden, aus der Horizontalen heraus vertikal in die Höhe hebt und in Taschen eines Revolvers fördert, der die Zigarettenpackungen anschließend weiterfördert. Der Hochheber dieser Hubförderer weist dabei horizontale Hubplatten auf, die mittels eines motorischen Antriebs sowie einer geeigneten Getriebeeinrichtung eine gewisse Wegstrecke nach oben hebbar sind.Such conveyors in manufacturing and / or packaging plants for the manufacture and / or packaging of cigarettes or the like are known in the art. For example, is from the DE 24 62 974 a cyclically operating lifting conveyor with a high lift known, the cigarette packs, which are conveyed to this horizontal, lifts vertically out of the horizontal and promotes in pockets of a revolver, which then further promotes the cigarette packs. The high lift this lifting conveyor has horizontal lifting plates, which are lifted by means of a motor drive and a suitable transmission device a certain distance upwards.

Die Zigarettenpackung liegt dabei während der Förderbewegung auf den horizontalen Hubplatten des Hochhebers auf. Der Hochheber wird nach einer abgeschlossenen Förderbewegung von der angehobenen Stellung wieder nach unten bewegt, um die nächste Zigarettenpackung nach oben fördern zu können. Er wird demnach taktweise angehoben bzw. wieder nach unten geführt.The cigarette pack rests during the conveying movement on the horizontal lifting plates of the high lift. The high lifter is moved back from the raised position after a completed conveying movement to be able to promote the next cigarette pack upwards. He is therefore cyclically raised or guided down again.

Weiter ist im Stand der Technik bekannt, den Hochheber nicht anzuheben, sollte die Steuerung eine Fehlpackung registriert haben. In diesem Fall wird die Zigarettenpackung an dem in der unteren Grundposition verharrenden Hochheber vorbeigefördert und ausgeschleust. Um bei rotierender Antriebswelle des Antriebsmotors zu ermöglichen, dass der Hochheber dieser Grundposition verharrt, wird der - im Stand der Technik häufig federbelastete - Hochheber in seiner Bewegung blockiert, etwa durch eine Klinke, die eine weitere Bewegung des Hochhebers unterbindet. Durch diese Blockade werden naturgemäß verschiedene Teile der Mechanik des Hochhebers mit großen Kräften belastet, da sämtliche Antriebskräfte auch während der Blockade weiterhin auf den Hochheber wirken. Die Blockade erfolgt ausschließlich dadurch, dass den Antriebskräften Blockadekräfte entgegengesetzt werden.Further, it is known in the art not to raise the high lifter should the controller have registered a miss pack. In this case, the packet of cigarettes is conveyed past and removed from the high-lift, which remains in the lower basic position. In order to allow for rotating drive shaft of the drive motor that the lifter remains this basic position, the - in the art often spring loaded - high lifter is blocked in its movement, such as a pawl, which prevents further movement of the high lifter. By this blockade naturally different parts of the mechanics of the high lift are loaded with great forces, since all driving forces continue to act on the high lift even during the blockade. The blockage takes place exclusively by blocking forces being applied to the drive forces.

Bei den Hubförderern des Standes der Technik ist des Weiteren nachteilig, dass wegen der steigenden Verpackungsgeschwindigkeiten der Verpackungsmaschinen deren vorgespannte Federn zu Eigenresonanz neigen. Der Hochheber des Hubförderers muss bei jedem Takt gegen die Feder arbeiten und beansprucht diese stark.In the lifting conveyors of the prior art is also disadvantageous that tend due to the increasing packaging speeds of the packaging machines whose biased springs to natural resonance. The lift of the lifting conveyor must work against the spring at every stroke and demands it heavily.

Ausgehend von diesem Stand der Technik ist es Aufgabe der vorliegenden Erfindung, die eingangs genannten Fördervorrichtungen weiterzuentwickeln. um auch bei hohen Fördertakten bzw. Fördergeschwindigkeiten einen möglichst zuverlässigen und verschleißarmen Förderbetrieb zu gewährleisten.Based on this prior art, it is an object of the present invention to further develop the above-mentioned conveyor devices. in order to ensure the most reliable and low-wear conveying operation even at high conveying cycles or conveying speeds.

Diese Aufgabe wird gelöst durch eine Vorrichtung zur Förderung von Produkten, vorzugsweise Zigarettenpackungen, in einer Fertigungs- und/oder Verpackungsanlage zur Herstellung und/oder Verpackung von Zigaretten oder anderen rauchbaren Artikeln mit den Merkmalen des Anspruches 1. Die Aufgabe wird des Weiteren gelöst durch eine entsprechende Fertigungs- und/oder Verpackungsanlage mit den Merkmalen des Anspruches 8.This object is achieved by a device for conveying products, preferably cigarette packets, in a production and / or packaging installation for producing and / or packaging cigarettes or other smokable articles having the features of claim 1. The object is further achieved by a corresponding production and / or packaging installation with the features of claim 8.

Demnach ist die Fördervorrichtung unter anderem dadurch gekennzeichnet, dass deren Getriebeeinrichtung mindestens ein Getriebeglied aufweist, das durch einen steuerbaren Aktor zwischen einer ersten Stellung, in der die Getriebeeinrichtung die Förderbewegung des Förderteils, insbesondere die Hubbewegung des Hochhebers, bei rotierender Antriebswelle der Antriebseinheit unterbindet, insbesondere keine Antriebsbewegung, bevorzugt keine Antriebskräfte, auf das Förderteil überträgt - Sperrstellung - und einer zweiten Stellung, in der die Getriebeeinrichtung die Förderbewegung des Förderteils bei rotierender Antriebswelle ermöglicht, insbesondere eine Antriebsbewegung, bevorzuckt Antriebskräfte, auf das Förderteil überträgt - Freistellung - steuerbar hin- und/oder herbewegbar ist.Accordingly, the conveyor device is characterized, inter alia, by the fact that its transmission device has at least one transmission element which, by a controllable actuator between a first position in which the transmission device prevents the conveying movement of the conveyor part, in particular the lifting movement of the high lift, with rotating drive shaft of the drive unit, in particular no drive movement, preferably no driving forces, transmits to the conveyor part - blocking position - and a second position in which the transmission device allows the conveying movement of the conveyor part with a rotating drive shaft, in particular a drive movement, vorzuckt Driving forces on the conveyor part transmits - exemption - controllable back and / or forth is movable.

Mittels eines steuerbaren Aktors, beispielsweise mittels eines Pneumatik- oder Hydraulikzylinders mit einem in dem Zylinder hin- und/oder herbewegbaren Kolbens, ist es möglich, ein Getriebeglied der Getriebeeinrichtung so zu steuern, dass die Getriebeeinrichtung abhängig von der Stellung des Getriebegliedes in die Sperrstellung überführt wird oder in die Freistellung. Die Getriebeeinrichtung selbst wird daher bedarfsweise so gesteuert, dass die Förderbewegung des Förderteils ausführbar ist oder dass diese Förderbewegung gesperrt ist, bzw. dass eine Bewegungs- oder Kraftübertragung auf das Förderteil erfolgt oder unterbunden wird. Eine separate Blockadeeinrichtung wie im Stand der Technik ist nicht mehr notwendig, das Getriebe selbst wird zwischen den beiden Zuständen bedarfsweise hin- und/oder hergeschaftet. Die Krafteinwirkungen auf den Hochheber in der Sperrstellung können bei dieser Lösung gegenüber dem Stand der Technik deutlich verringert oder sogar auf Null reduziert werden.By means of a controllable actuator, for example by means of a pneumatic or hydraulic cylinder with a reciprocating piston in the cylinder, it is possible to control a transmission member of the transmission device so that the transmission device is transferred depending on the position of the transmission member in the locked position will or will be released. The transmission device itself is therefore controlled, if necessary, so that the conveying movement of the conveyor part is executable or that this conveying movement is locked, or that a movement or power transmission takes place on the conveyor part or is prevented. A separate blockage device as in the prior art is no longer necessary, the transmission itself is needed back and / or forth between the two states. The force effects on the high lift in the blocking position can be significantly reduced or even reduced to zero in this solution over the prior art.

Die Getriebeeinrichtung weist erfindungsgemäß ein Antriebsgetriebeteil auf sowie ein Führungsgetriebeteil, wobei mit dem Antriebsgetriebeteil Drehbewegungen der rotierenden, durch einen Antriebsmotor angetriebenen Abtriebswelle in geeignete Antriebsbewegungen zum Antrieb des das Förderteil entlang eines Kreisbahnabschnittes führenden Führungsgetriebeteils umwandelbar sind.According to the invention, the transmission device has a drive transmission part and a guide transmission part, rotational movements of the rotating drive shaft driven by a drive motor being convertible into suitable drive movements for driving the guide transmission part leading along a circular path section with the drive transmission part.

Das von dem Aktor bewegbare Getriebeglied ist ein erster Schenkel eines ersten kniehebelförmigen Getriebeteils des Antriebsgetriebeteils der Getriebeeinrichtung, dessen zweiter Schenkel mit einem zweiten kniehebelförmigen Getriebeteil des Antriebsgetriebeteils der Getriebeeinrichtung verbunden ist. Die Verbindung ist derart ausgestaltet, dass der zweite Schenkel des ersten kniehebelförmigen Getriebeteils und ein diesem zugeordneter, erster Schenkel des zweiten kniehebelförmigen Getriebeteils unter Bildung einer gemeinsamen Drehachse über eine Gelenkverbindung, insbesondere ein Drehgelenk, miteinander verbunden sind.The movable by the actuator gear member is a first leg of a first toggle-shaped gear part of the drive gear part of the transmission device, the second leg is connected to a second toggle-shaped gear part of the drive gear part of the transmission device. The connection is configured such that the second leg of the first toggle-lever-shaped gear part and a first leg of the second toggle-shaped gear part assigned thereto are connected to one another to form a common axis of rotation via an articulated connection, in particular a rotary joint.

Das diese beiden Schenkel verbindende Gelenk wird im Rahmen der Anmeldung als Kniegelenk bezeichnet. Die Schenkel können endständig wiederum über weitere Gelenke mit anderen Bauteilen, insbesondere Getriebeteilen, verbunden sein, sie müssen dies aber nicht.In the context of this application, a "toggle-shaped gear part" is understood to mean a gear part which, like a toggle lever, has at least two gear elements connected to one another via a joint, in particular a rotary joint, namely limbs. The joint connecting these two legs is referred to as a knee joint in the context of the application. The legs can be terminal connected via other joints with other components, in particular transmission parts, but they do not have this.

Ein zweiter Schenkel des zweiten kniehebelförmigen Getriebeteils ist über eine Gelenkverbindung, insbesondere ein Drehgelenk, an dem das Produkt mindestens zeitweise kontaktierenden Förderteil mittelbar oder unmittelbar angelenkt. Der erste Schenkel des ersten kniehebelförmigen Getriebeteils ist mittelbar oder unmittelbar drehbar an einem Gehäuse oder einem anderen ortsfesten Teil der Fertigungs- und/oder Verpackungsanlage befestigbar, insbesondere mit einer Gelenkverbindung, vorzugsweise einem Drehgelenk, das an dem der Gelenkverbindung zwischen den beiden Schenkeln des ersten kniehebelförmigen Getriebeteils - Kniegelenk - entgegengesetzten Ende des ersten Schenkels angeordnet ist.A second leg of the second knee-lever-shaped gear part is articulated via a joint connection, in particular a rotary joint, on which the product at least temporarily contacting conveying part indirectly or directly.

Fig. 1 zeigt eine Fertigungs- und/oder Verpakkungsanlage zur Herstellung und/oder Verpackung von Zigaretten oder anderen rauchbaren Artikeln, nämlich eine Verpackungsmaschine 10 (Packer) zur Herstellung von Zigarettenpackungen 11 des Typs Klappschachtel (Hinge-Lid-Packung). Die Verpackungsmaschine 10 arbeitet taktweise und ist für einen zweibahnigen Betrieb ausgelegt. Fig. 1 shows a manufacturing and / or packaging plant for the manufacture and / or packaging of cigarettes or other smokable articles, namely a packaging machine 10 (packer) for the production of cigarette packs 11 of the type hinge-lid (hinge-lid pack). The packaging machine 10 works in cycles and is designed for a two-lane operation.

In der Verpackungsmaschine 10 werden Pakkungszuschnitte 12 aus einem Zuschnittmagazin 13 einem nicht explizit dargestellten Faltrevolver zugeführt. In dem Faltrevolver wird der jeweilige Zuschnitt 12 zu verschiedenen, entlang eines Kreisbogens angeordneten Faltstationen geführt, in denen komplexe Faltvorgänge in an sich bekannter Weise durchgeführt werden. Insbesondere werden dabei Zigarettenblöcke zugeführt, die von von Staniolbobinen 14 stammenden Zuschnitten umhüllt sind. Weiterwird dort ein Packungskragen in den Faltprozess eingeführt, wobei der Kragenzuschnitt von Kragenbobinen 15 stammt. Weiterwerden verschiedene Zuschnittbereiche jedes Zuschnitts in dem Faltrevolver mit Leim versehen und mit anderen Zuschnittsbereichen verklebt.In the packaging machine 10 Pakkungszuschnitte 12 are supplied from a blank magazine 13 a not explicitly shown Faltrevolver. In the folding turret, the respective blank 12 is guided to various folding stations arranged along a circular arc, in which complex folding operations are carried out in a manner known per se. In particular, cigarette blocks are supplied, which are enveloped by Staniolbobinen 14 originating blanks. Furthermore, a packing collar is introduced there in the folding process, wherein the collar cut comes from collar bobs 15. Furthermore, various blank sections of each blank in the folding turret are provided with glue and glued to other blank sections.

Nach Abschluss der Faltvorgänge werden die jeweiligen Packungen über zwei parallel zueinander verlaufende, horizontal ausgerichtete Förderbahnen 16 eines Horizontalförderers 17 in Richtung eines Übergaberevolvers 18 weitergefördert.Upon completion of the folding operations, the respective packages on two mutually parallel, horizontally oriented conveyor tracks 16 of a horizontal conveyor 17 in the direction of a transfer turret 18 on.

Im Endbereich dieses Horizontalförderers 17 ist ein weiterer Förderer 19, nämlich ein Hubförderer vorgesehen, der die von dem Horizontalförderer 17 geförderten Zigarettenpackungen übernimmt und dem Übergaberevolver 18 zuführt, indem er die Zigarettenpackungen 11 jeweils nach oben anhebt und in Taschen 20 des Übergaberevolvers 18 einführt. Die Taschen 20 weisen dabei jeweils bewegliche Wände 21, 22 auf, die nach innen auf die Zigarettenpackung 11 zubewegbar sind. Die Taschenwände sind derart geformt, dass sie die Zigarettenpackung 11 in geschlossener Stellung der Tasche 20 halten.In the end region of this horizontal conveyor 17, a further conveyor 19, namely a lifting conveyor is provided, which takes over the conveyed from the horizontal conveyor 17 cigarette packs and the transfer turret 18 feeds by lifting the cigarette packs 11 each up and inserted into pockets 20 of the transfer turret 18. The pockets 20 each have movable walls 21, 22, which are zubewegbar to the inside of the cigarette pack 11. The bag walls are shaped to hold the cigarette pack 11 in the closed position of the bag 20.

Der Übergaberevolver 18 übergibt die Zigarettenpackungen 11 anschließend einem Trockenrevolver 23, in dem die Packungen 11 zum Stabilisieren der Form und zum Austrocknen von Leimstellen verweilen.The transfer turret 18 then transfers the cigarette packs 11 to a drying turret 23, in which the packs 11 dwell to stabilize the mold and to dry out glue spots.

In Fig. 2 ist der Hubförderer 19 detaillierter dargestellt.In Fig. 2 the lifting conveyor 19 is shown in more detail.

Er weist eine unterhalb der Förderbahnen 16 angeordnete Getriebeeinrichtung 24 auf mit einem Antriebsgetriebeteil 25 sowie je einem Führungsgetriebeteil 26. Der Antriebsgetriebeteil 25 wandelt Drehbewegungen einer rotierenden Antriebswelle 27, die von einem nicht dargestellten Motor angetrieben wird, in geeignete Antriebsbewegungen zum Antrieb von zwei Förderteilen 28 um, nämlich Hochhebem 28. Jeweils einer Förderbahn 16 des Horizontalförderers 17 ist je ein Hochheber 28 des Hubförderers 19 zugeordnet, vgl. insbesondere Fig. 6. Entsprechend ist auch der Führungsgetriebeteil 26 zweimal vorhanden, nämlich für jeden Hochheber 28 ein separater Führungsgetriebeteil 26.It has a arranged below the conveyor tracks 16 gear device 24 with a drive gear part 25 and a respective guide gear part 26. The drive gear part 25 converts rotational movements of a rotating drive shaft 27, which is driven by a motor, not shown, in suitable drive movements for driving two conveyor parts 28 In each case a conveyor track 16 of the horizontal conveyor 17 is associated with a respective high lift 28 of the lifting conveyor 19, cf. especially Fig. 6 , Accordingly, the guide transmission part 26 is also present twice, namely for each high lift 28, a separate guide transmission part 26th

Jeder Führungsgetriebeteil 26 weist dabei eine Parallelführung 29 auf, nämlich zwei parallel und beabstandet zueinander angeordnete, schwenkbar über ortsfeste Drehgelenke 31 angelenkte Getriebeglieder 30. Die Getriebeglieder 30 jeder Parallelführung 29 sind mit ihrem dem jeweiligen Drehgelenk 31 entgegengesetzten Ende drehbar mit einer Hochhebergabel 32 des entsprechenden Hochhebers 28 verbunden, nämlich angelenkt über Gelenkverbindungen 33, nämlich über Drehgelenke 33. Der Führungsgetriebeteil 26, nämlich die Parallelführung 29, sorgt dafür, dass das jeweilige Förderteil 28 ausschließlich Bewegungen ausführen kann, die entlang eines Kreisbahnabschnittes bzw. Kreisbogens verlaufen.Each guide gear part 26 has a parallel guide 29, namely two parallel and spaced from each other, pivotally articulated via stationary hinges 31 geared members 30. The gear members 30 each parallel guide 29 are rotatable with their respective pivot 31 opposite end with a high-lift fork 32 of the corresponding high lift The guide transmission part 26, namely the parallel guide 29, ensures that the respective conveying part 28 can only perform movements that run along a circular path section or circular arc.

Einzelne Bauteile des im folgenden beschriebenen Antriebsgetriebeteils 25 sind nur einfach vorhanden und somit funktional beiden Hochhebem 28 zugeordnet. Andere Bauteile sind doppelt vorhanden, sodass jedem der beiden Hochheber 28 je eines dieser Bauteile zugeordnet ist.Individual components of the drive transmission part 25 described below are only present in a simple manner and are thus assigned functionally to both elevators 28. Other components are duplicated, so that each of the two elevators 28 each one of these components is assigned.

Der Antriebesgetriebeteil 25 verfügt über eine mit der Antriebswelle 27 wirkverbundene Kurvenscheibe 34. Die Kurvenscheibe 34 treibt einen sich um ein ortsfestes Drehgelenk 35 drehenden Rollenhebel 36 mit mehreren Hebelarmen an. Ein Hebelarm 37 des Rollenhebels 36 führt bei Rotation der Kurvenscheibe 34 in der Rotationsebene Drehbewegungen, nämlich Hin- und/ oder Herbewegungen aus. In der Fig. 2 ist dabei ein Betriebszustand dargestellt, in dem der Hebelarm 37 nach unten bewegt wird. Endständig ist der Hebelarm 37 des Rollenhebels 36 mit einem Zwischenglied 39 über ein Drehgelenk 40 verbunden. Das Zwischenglied 39 wiederum ist über ein weiteres Drehgelenk 41 mit einem ersten Arm 44 eines symmetrischen, um eine durch ein ortsfestes Drehgelenk 42 definierte Drehachse Hin- und/ oder Herbewegungen ausführenden Übertragungshebel 43 gelenkig verbunden.The drive gear part 25 has a cam plate 34 operatively connected to the drive shaft 27. The cam plate 34 drives a roller lever 36 rotating about a stationary rotary joint 35 with a plurality of lever arms. A lever arm 37 of the roller lever 36 performs upon rotation of the cam 34 in the plane of rotation rotational movements, namely back and / or forth movements. In the Fig. 2 In this case, an operating state is shown, in which the lever arm 37 is moved downward. Terminally, the lever arm 37 of the roller lever 36 is connected to an intermediate member 39 via a swivel joint 40. The intermediate member 39 in turn is connected via a further rotary joint 41 with a first arm 44 of a symmetrical, about a defined by a fixed rotary joint 42 axis of rotation out and / or forth movements transfer lever 43 hinged.

Die Kurvenscheibe 34, der Rollenhebel 36 sowie der Hebelarm 37 sind nur einfach vorhanden, dienen mithin zum Antrieb der beiden Hochheber 28.The cam 34, the roller lever 36 and the lever arm 37 are only available in a simple way, thus serving to drive the two elevators 28th

Der Übertragungshebel 43 weist zu diesem Zweck zu beiden Seiten der durch das Drehgelenk 42 des Übertragungshebels 43 definierten Drehachse beidseitig Hebelarme auf, nämlich den vorgenannten ersten Hebelarm 44 auf der "Antriebsseite" und zwei zweite Hebelarme 45 auf der "Abtriebsseite". Jeder der beiden zweiten Hebelarme 45 des Übertragungshebels 43 dient einzeln dazu, Antriebsbewegungen auf den dem jeweiligen Hebelarm 45 zugeordneten Hochheber 28 zu übertragen.The transmission lever 43 has for this purpose on both sides of the rotational axis defined by the pivot 42 of the transmission lever 43 on both sides lever arms, namely the aforementioned first lever arm 44 on the "drive side" and two second lever arms 45 on the "output side". Each of the two second lever arms 45 of the transmission lever 43 is used individually to transmit drive movements on the respective lever arm 45 associated high lift 28.

Besonders wichtig sind im Weiteren ein erstes kniehebelförmiges Getriebeteil 46 und ein zweites kniehebelförmiges Getriebeteil 47 des Antriebsgetriebeteils 25. Die nachfolgend beschriebene Anordnung aus kniehebelförmigen Getriebeteilen 46, 47 ist zweifach vorhanden, nämlich je Hochheber 28 einmal. Der Einfachheit halber werden die Zusammenhänge nur für einen der Hochheber 28 beschrieben:In the following, a first toggle-shaped gear part 46 and a second toggle-shaped gear part 47 of the drive gear part 25 are particularly important. The arrangement of toggle-shaped gear parts 46, 47 described below is present twice, namely once each high-lift 28. For the sake of simplicity, the relationships are described for only one of the elevators 28:

Das zweite kniehebelförmige Getriebeteil 47 weist zwei über eine Gelenkverbindung 48, nämlich ein Drehgelenk, miteinander verbundene Schenkel 49, 50 auf. Die Gelenkverbindung 48 wird im Folgenden als Kniegelenk bezeichnet. Der erste Schenkel 49 des zweiten kniehebelförmigen Getriebeteils 47 ist endständig mit einem der beiden zweiten Hebelarme 45 des Übertragungshebels 43 verbunden, und zwar über ein Drehgelenk 51. Der zweite Schenkel 50 des zweiten kniehebelförmigen Getriebeteils 47 ist mittels eines Drehgelenks 52 an dem Hochheber 28 angelenkt.The second toggle-shaped gear part 47 has two via a hinge connection 48, namely a hinge, interconnected legs 49, 50. The articulated connection 48 is referred to below as a knee joint. The first leg 49 of the second toggle-shaped transmission part 47 is connected terminally to one of the two second lever arms 45 of the transmission lever 43, via a pivot 51. The second leg 50 of the second toggle-shaped transmission part 47 is articulated by means of a pivot 52 on the high lift 28.

Das erste kniehebelförmige Getriebeteil 46 weist ebenfalls einen ersten Schenkel 54 auf sowie einen zweiten Schenkel 55, die miteinander über eine gemeinsame, im Folgenden ebenfalls als Kniegelenk bezeichnete Gelenkverbindung 53, nämlich ein Drehgelenk, verbunden sind. Der erste Schenkel 54 dieses ersten kniehebelförmigen Getriebeteils 46 ist mittels eines ortsfest insbesondere an dem Gehäuse der Verpackungsmaschine 10 angeordneten Drehgelenks 56 drehbar gelagert. Der zweite Schenkel 55 des ersten kniehebelförmigen Getriebeteils 46 ist an seinem dem Drehgelenk 53 gegenüberliegendem Ende mittels eines Drehgelenks 57 drehbar an einem länglichen Verbindungsteil 58 angelenkt, das sich mindestens abschnittsweise entlang der durch das Drehgelenk 48 definierten Drehachse des zweiten kniehebelförmigen Getriebeteils 47 erstreckt und das mit dem zweiten kniehebelförmigen Getriebeteil 47 verbunden ist.The first toggle-shaped gear part 46 also has a first leg 54 and a second leg 55, which are connected to each other via a common, hereinafter also referred to as a knee joint articulation 53, namely a hinge. The first leg 54 of this first toggle lever-shaped gear part 46 is rotatably supported by means of a pivotally arranged in particular on the housing of the packaging machine 10 pivot joint 56. The second leg 55 of the first toggle-shaped gear part 46 is pivoted at its opposite end to the pivot 53 by means of a pivot joint 57 to an elongated connecting part 58, that extends at least in sections along the axis of rotation of the second toggle-shaped gear part 47 defined by the pivot 48 and that is connected to the second toggle-shaped gear part 47.

Die Anlenkung des Drehgelenkes 57 an dem mit dem zweiten kniehebelförmigen Getriebeteil 48 verbundenen, länglichen Verbindungsteil 58 erfolgt dabei derart, dass die durch dieses Drehgelenk 57 definierte Drehachse mit derjenigen Drehachse zusammenfällt, die durch das Kniegelenk 48 des zweiten kniehebelförmigen Getriebeteils 47 definiert ist. Das Kniegelenk 48 des zweiten kniehebelförmigen Getriebeteils 47 einerseits und der zweite Schenkel 55 des ersten kniehebelförmigen Getriebeteils 46, insbesondere der Endbereich dieses Schenkels 55, drehen sich mit anderen Worten um eine gemeinsame Drehachse.The articulation of the rotary joint 57 on the connected to the second knee lever-shaped transmission part 48, elongated connecting part 58 is effected such that the axis of rotation defined by this pivot 57 coincides with that axis of rotation which is defined by the knee joint 48 of the second toggle lever-shaped transmission part 47. The knee joint 48 of the second toggle-shaped gear part 47 on the one hand and the second leg 55 of the first toggle-shaped gear part 46, in particular the end portion of this leg 55, rotate in other words about a common axis of rotation.

Die räumliche Position des ersten kniehebelförmigen Getriebeteils 46, insbesondere des ersten Schenkels 54, ist mittels eines durch eine nicht dargestellte Steuer- und/oder Regelungseinrichtung steuerbaren Aktors 59 veränderbar. Der Aktor 59 verfügt über einen ortsfest drehbar - etwa an einem Gehäuse - angelenkten Pneumatik-Zylinder 60, dessen Kolben 61, nämlich die Kolbenstange 62 des Kolbens 61, an dem ersten Schenkel 54 des ersten kniehebelförmigen Getriebeteils 46 mit einem Drehgelenk 63 drehbar angelenkt ist, und zwar derart, dass Bewegungen des Kolben 61 innerhalb des Pneumatik-Zylinders 60 zu Drehungen des ersten kniehebelförmigen Getriebeteils 46 um die durch das ortsfeste Drehgelenk 56 definierte Drehachse führen.The spatial position of the first toggle-shaped gear part 46, in particular of the first leg 54, is variable by means of a controllable by a control and / or regulating device, not shown actuator 59. The actuator 59 has a stationary rotatable - about a housing - articulated pneumatic cylinder 60, the piston 61, namely the piston rod 62 of the piston 61, is rotatably articulated to the first leg 54 of the first toggle-shaped gear part 46 with a pivot joint 63, in such a way that movements of the piston 61 within the pneumatic cylinder 60 lead to rotations of the first toggle-shaped gear part 46 about the defined by the fixed pivot 56 axis of rotation.

Durch Steuerung des Aktors 59, nämlich durch Verfahren des Kolbens 61, kann die Getriebeeinrichtung 24 zwei unterschiedliche Betriebsstellungen einnehmen:By controlling the actuator 59, namely by moving the piston 61, the transmission device 24 can assume two different operating positions:

In einer ersten, freien Betriebsstellung - im Folgenden als Freistellung bezeichnet-der Getriebeeinrichtung 24, befindet sich der Koben 61 in einer eingefahrenen Grundposition innerhalb des Zylinders 60 (Fig. 2 und 3). In dieser Grundposition befinden sich einerseits die Drehachse, die durch die Gelenkverbindung 52 zwischen dem an dem Hochheber 28 angelenkten Schenkel 50 des zweiten kniehebelförmigen Getriebeteils 47 und dem Hochheber 28 definiert ist, und andererseits die Drehachse, die durch die Gelenkverbindung zwischen den beiden Schenkeln des ersten kniehebelförmigen Getriebeteils 46, nämlich das Kniegelenk 53 definiert ist, nicht in Überdeckung, d.h. sie fluchten nicht, sondern sind vielmehr voneinander deutlich beabstandet. In dieser Freistellung der Getriebeeinrichtung 24 überträgt die Getriebeeinrichtung 24 bei rotierender Antriebswelle 27 die entsprechenden Antriebskräfte über den Führungsgetriebeteil 26 auf den Hochheber 28, sodass der Hochheber 28 bei einer vollen Umdrehung der Antriebswelle 27 ausgehend von der in Fig. 2 gezeigten Ausgangsstellung eine Hubbewegung nach oben ausführt sowie im Anschluss daran eine Rückbewegung in die Ausgangsstellung.In a first, free operating position-hereinafter referred to as the exemption-of the transmission device 24, the piston 61 is in a retracted basic position within the cylinder 60 (FIG. Fig. 2 and 3 ). In this basic position are on the one hand, the axis of rotation, which is defined by the articulation 52 between the hinged to the jack 28 legs 50 of the second toggle-shaped transmission part 47 and the lifter 28, and on the other hand, the axis of rotation, by the hinge connection between the two legs of the first knee lever-shaped gear part 46, namely the knee joint 53 is defined, not in overlap, ie they are not aligned, but rather are clearly spaced from each other. In this exemption of the transmission device 24 transmits the transmission device 24 with rotating drive shaft 27, the corresponding drive forces on the guide gear member 26 on the lifter 28, so that the high lift 28 at a full rotation of the drive shaft 27, starting from the in Fig. 2 shown starting position performs a lifting movement upward and then a return movement to the starting position.

Die Hochhebergabel 32 des Hochhebers 28 weist zu diesem Zweck endständig abschnittsweise horizontal verlaufende Paare von Hubteilen 65 auf, wobei die Hubteile 65 jeweils parallel zueinanderverlaufen und voneinander beabstandet sind. Die Hubteile 65 sind in der oben beschriebenen Ausgangstellung des Hochhebers 28 in die Förderbahn 16 des Horizontalförderers 17 eingelassen, nämlich in entsprechende Schlitze 66 in der Förderbahn 16. Die einzelnen Zigarettenpackungen 11 werden von einem Fördertrum 64 des Horizontalförderes 17 zugeordneten Mitnehmern 67 entlang der entsprechenden Förderbahn 16 des Horizontalförderers 17 in Richtung des Hubförderers 19 bewegt. Sobald sich die jeweilige Zigarettenpackung 11 in Förderrichtung auf Höhe der Hubteile 65 des Hubförderers 19 befindet, werden die Hubteile 65 durch Bewegung des Hochhebers 28 unter Mitnahme der Zigarettenpackung 11 nach oben bewegt (Fig. 3). Endständige, insbesondere vertikal verlaufende Anschläge 68 an gegenüberliegenden Seiten der Hubteile 65 sorgen dafür, dass die Zigarettenpackung 11 während der einen Kreisbahnabschnitt beschreibenden Hubbewegung nicht von der Hochhebergabel 32 nach unten fällt.The high lifting fork 32 of the high lift 28 has for this purpose terminal sections horizontally extending pairs of lifting parts 65, wherein the lifting parts 65 are each parallel to each other and spaced from each other. The lifting parts 65 are embedded in the above-described starting position of the high lift 28 in the conveyor track 16 of the horizontal conveyor 17, namely in corresponding slots 66 in the conveyor track 16. The individual cigarette packs 11 are associated with a conveying strand 64 of the horizontal conveyor 17 entrainment 67 along the corresponding conveyor track 16 of the horizontal conveyor 17 in the direction of the lifting conveyor 19 moves. As soon as the respective cigarette pack 11 is in the conveying direction at the height of the lifting parts 65 of the lifting conveyor 19, the lifting parts 65 are moved by moving the high lifter 28 with the cigarette packet 11 upwards ( Fig. 3 ). Terminal, in particular vertically extending stops 68 on opposite sides of the lifting parts 65 ensure that the cigarette pack 11 does not fall down from the lifting fork 32 during the lifting movement describing a circular path section.

In einer zweiten, sperrenden Betriebsstellung - im Folgenden als Sperrstellung bezeichnet - der Getriebeeinrichtung 24, befindet sich der Koben 61 in einer ausgefahrenen Position innerhalb des Zylinders 60. Durch das Ausfahren des Kolbens 61 in diese End-Position wird der mit der Kolbenstange 62 verbundene erste Schenkel 54 des ersten kniehebelförmigen Getriebeteils 46 um die durch das Drehgelenk 56 definierte Drehachse im Uhrzeigersinn verdreht. In dieser Sperrstellung befinden sich einerseits die Drehachse, die durch die Gelenkverbindung 52 zwischen dem an dem Hochheber 28 angelenkten Schenkel 50 des zweiten kniehebelförmigen Getriebeteils 47 und dem Hochheber 28 definiert ist, und andererseits die Drehachse, die durch die Gelenkverbindung 53 zwischen den beiden Schenkeln des ersten kniehebelförmigen Getriebeteils 46, nämlich das Kniegelenk 53 definiert ist, in Überdeckung, d.h. sie fluchten. Dies führt infolge verschiedener getriebetechnischer Zusammenhänge dazu, dass der Hochheber 28 in dieser Sperrstellung nicht angetrieben wird. Eine Zigarettenpackung 11, die zuvor als fehlerhaft erkannt worden ist, kann daher an dem in dieser Stellung keine Hubbewegung ausführenden Hochheber 28 vorbeigefördert und ausgeschleust werden.In a second, blocking operating position - hereinafter referred to as blocking position - the transmission device 24, the piston 61 is in an extended position within the cylinder 60. By extending the piston 61 in this end position of the piston rod 62 is connected to the first Leg 54 of the first toggle-shaped gear part 46 is rotated about the axis defined by the pivot 56 axis of rotation in a clockwise direction. In this blocking position are on the one hand, the axis of rotation, which is defined by the articulation 52 between the hinged to the jack 28 leg 50 of the second toggle-shaped transmission part 47 and the lifter 28, and on the other hand, the axis of rotation, through the hinge joint 53 between the two legs of the first knee lever-shaped gear part 46, namely the knee joint 53 is defined, in overlap, ie they flee. This leads due to various gearbox technical contexts that the high lift 28 is not driven in this locked position. A cigarette pack 11, which has previously been identified as faulty, can therefore be conveyed past and removed from the lifting device 28, which carries out no lifting movement in this position.

Die einzelnen, durch die jeweiligen Gelenkverbindungen der Getriebeeinrichtung 24 definierten Drehachsen sind bei der vorliegenden Ausführungsformen sämtlich parallel zueinander angeordnet. Wie der Fachmann des Standes der Technik erkennt, ist dies allerdings nicht zwingend notwendig..The individual axes of rotation defined by the respective articulations of the transmission device 24 are all arranged parallel to one another in the present embodiment. However, as the person skilled in the art recognizes, this is not absolutely necessary.

Was die Abstände der einzelnen Drehachsen zueinander angeht, so gilt Folgendes: Der Abstand zwischen der Drehachse, die durch das Kniegelenk 53 des ersten kniehebelförmigen Getriebeteils 46 definiert ist und der Drehachse, die durch die Gelenkverbindung 56 zwischen dem ersten Schenkel 54 des ersten kniehebelförmigen Getriebeteils 46 und dem Gehäuse oder einem anderen ortsfesten Teil der Verpackungsmaschine 10 definiert ist, ist identisch oder nahezu identisch zu dem Abstand zwischen dieser Kniegelenk-Drehachse des ersten kniehebelförmigen Getriebeteils 46 und der Drehachse, die durch die Gelenkverbindung 57 zwischen dem zweiten Schenkel 55 des ersten kniehebefförmigen Getriebeteils 46 und dem zweiten kniehebelförmigen Getriebeteil 47 definiert ist.As regards the distances of the individual axes of rotation to each other, the following applies: The distance between the axis of rotation, which is defined by the knee joint 53 of the first toggle-shaped gear part 46 and the axis of rotation, by the hinge connection 56 between the first leg 54 of the first toggle lever Gear part 46 and the housing or other stationary part of the packaging machine 10 is identical or nearly identical to the distance between this knee joint rotational axis of the first toggle-shaped gear part 46 and the axis of rotation, through the hinge joint 57 between the second leg 55 of the first knee-lever-shaped gear part 46 and the second toggle-shaped gear part 47 is defined.

Der Abstand zwischen der Drehachse, die durch das Kniegelenk 48 des zweiten kniehebelförmigen Getriebeteils 47 definiert ist und der Drehachse, die durch die Gelenkverbindung 52 an dem dem Hochheber 28 zugeordneten Schenkel 50 des zweiten kniehebelförmigen Getriebeteils 47 definiert ist, ist identisch oder nahezu identisch zu dem Abstand zwischen der Kniegelenk-Drehachse des ersten kniehebelförmigen Getriebeteils 46 und der Drehachse, die durch die Gelenkverbindung 57 zwischen dem ersten kniehebelförmigen Getriebeteil 46 und dem zweiten kniehebelförmigen Getriebeteil 47 definiert ist.The distance between the axis of rotation defined by the knee joint 48 of the second toggle-shaped gear portion 47 and the axis of rotation defined by the hinge 52 on the leg 50 of the second toggle-shaped gear portion 47 associated with the lifter 28 is identical or nearly identical to that Distance between the knee joint rotational axis of the first toggle-shaped gear part 46 and the rotation axis, which is defined by the hinge joint 57 between the first toggle-shaped gear part 46 and the second toggle-shaped gear part 47.

Wie oben erwähnt, sind jeweils zwei Hochheber 28 vorhanden. Jederder Hochheber kann separatmittels eines dem jeweiligen Hochheber 28 zugeordneten Aktors 59 separat gesteuert werden. Daher kann auf der ersten Förderbahn 16 die Bewegung des Hochhebers 28 gesperrt sein, auf derzweiten Förderbahn 16 dagegen nicht und umgekehrt.As mentioned above, there are two elevators 28 each. Each of the elevators can be separately controlled by means of an actuator 59 associated with the respective lifter 28. Therefore, on the first conveyor track 16, the movement of the high lift 28 may be disabled, but not on the second conveyor track 16, and vice versa.

Fig. 7 zeigt schließlich das Verhalten des erfindungsgemäßen Hubförderers 19, falls auf den Hochheber 28, insbesondere auf die Hubteile 65 von oben ein Druck bestimmter Größe ausgeübt wird. Beispielsweise kann eine auf den Hubteilen 65 aufliegende, verbeulte Zigarettenpackung 11, die beim Hochheben in Richtung der Taschen 20 des Übergaberevolvers 18 fehlerhaft in die Taschen 20 gepresstwird, einen Gegendruck auf den Hochheber 28 ausüben. Fig. 7 finally shows the behavior of the lifting conveyor 19 according to the invention, if on the high lift 28, in particular on the lifting parts 65 from above a pressure of certain size is exercised. For example, a dented cigarette packet 11 lying on the lifting parts 65, which is incorrectly pressed into the pockets 20 when lifted in the direction of the pockets 20 of the transfer turret 18, can exert a counterpressure on the high lift 28.

Die Getriebeeinrichtung 24, insbesondere die beiden kniehebelförmigen Getriebeteile 46,47, sind derart ausgebildet, dass durch einen auf den Hochheber 28 ausgeübten Druckgeeigneter Größe ein Einknicken mindestens des ersten kniehebelförmigen Getriebeteils 46 um dessen Kniegelenk 53 bewirkbar ist. Dieses Einknikken verursacht in der in der Fig. 7 dargestellten Freistellung der Getriebeeinrichtung 24 ein in der Freistellung eigentlich unzulässiges Ausfahren des Kolbens 61 aus der Grundposition. Dieses Ausfahren ist mit einem dem Zylinder 60 zugeordneten Sensor 69, der eine unzulässige Positionsveränderung detektieren kann, als fehlerhafter Betriebszustand detektierbar. Der Sensor 69 ist in diesem Fall ein entsprechendes Fehlersignal aus. Mittels der nicht dargestellten Steuerungs- und/oder Regelungseinrichtung können bei Auftreten des entsprechenden Fehlersignals geeignete Maßnahmen eingeleitet werden, etwa ein Maschinenstopp der Verpackungsmaschine 10.The transmission device 24, in particular the two toggle-shaped gear parts 46, 47, are designed such that buckling of at least the first toggle-shaped gear part 46 about the knee joint 53 thereof can be effected by a pressure on the high-lift 28 of suitable size. This Einknikken caused in the in the Fig. 7 illustrated exemption of the transmission device 24 in the release actually inadmissible extension of the piston 61 from the basic position. This extension is detectable as a faulty operating state with a sensor 60 assigned to the cylinder 60, which sensor can detect an impermissible change in position. The sensor 69 is in this case a corresponding error signal. By means of the control and / or regulating device, not shown, suitable measures can be initiated when the corresponding error signal occurs, for example a machine stop of the packaging machine 10.

Schließlich weist die Getriebeeinrichtung 24 noch die Besonderheit auf, dass in dessen Freistellung unterschiedliche Hübe, nämlich unterschiedliche Hübhöhen bzw. Hublängen des Hochhebers 28 einstellbar sind. Dazu kann die Grundposition des Kolben 61, in der der Kolben 61 in den Zylinder 60 eingefahren ist, durch geeignete Verstelleinrichtungen verstellt bzw. eingestellt werden. Demnach wird die in den Zylinder 60 eingefahrene Länge des Kolben 61 eingestellt.Finally, the transmission device 24 still has the peculiarity that in its exemption different strokes, namely different Hübhöhen or stroke lengths of the high lift 28 are adjustable. For this purpose, the basic position of the piston 61, in which the piston 61 is retracted into the cylinder 60, adjusted or adjusted by suitable adjustment. Accordingly, the retracted into the cylinder 60 length of the piston 61 is adjusted.

Wenn in der Freistellung der Getriebeeinrichtung 24 die Grundposition des Kolben 61 gegenüber einer ersten bzw. einer Standard-Grundposition derart verändert wird, dass der Kolben 61 gegenüber der Standard-Grundposition etwas ausgefahren wird, wird die räumliche Position des ersten Schenkels 54 des ersten kniehebelförmigen Getriebeteils 46 leicht verändert: Der Schenkel 54 wird etwas im Uhrzeigesinn um das Drehgelenk 56 gedreht. Dadurch knickt das zweite kniehebelförmige Getriebeteil 47 leicht um dessen Kniegelenk 48 nach unten ein, d.h. der entsprechende Winkel zwischen dessen Schenkeln 49, 50 wird kleiner. Dies bewirkt im Ergebnis einen geringeren Hub des Hochhebers 28.In the release of the transmission device 24, when the base position of the piston 61 is changed from a first or standard home position to slightly extend the piston 61 from the standard home position, the spatial position of the first leg 54 of the first toggle-type transmission part becomes 46 slightly changed: The leg 54 is rotated slightly clockwise about the pivot 56. As a result, the second toggle-type transmission member 47 bends slightly downwardly about the knee joint 48 thereof, i.e., the knee-jointed transmission member 47 is bent. the corresponding angle between its legs 49, 50 is smaller. As a result, this causes a smaller stroke of the high lift 28.

Umgekehrt wird bei einem Einfahren des Kolbens 61 gegenüber der Standard-Grundstellung der Hub vergrößert: Der Schenkel 54 wird etwas gegen den Uhrzeigersinn um das Drehgelenk 56 gedreht. Dadurch wird das zweite kniehebelförmige Getriebeteil 47 leicht um dessen Kniegelenk 48 gestreckt, d.h. der Winkel zwischen dessen Schenkeln 49,50 wird größer. Dies bewirkt im Ergebnis einen größeren Hub des Hochhebers 28.Conversely, when retracting the piston 61 relative to the standard basic position, the stroke is increased: The leg 54 is rotated somewhat counterclockwise about the pivot 56. As a result, the second toggle-shaped gear member 47 is stretched slightly about the knee joint 48, i. the angle between its legs 49,50 gets bigger. As a result, this causes a larger stroke of the high lift 28th
