Description

Die Erfindung betrifft ein Verfahren zum Zertrennen mindestens eines endlosen bewegten Stranges der tabakverarbeitenden Industrie in stabförmige Einzelartikel mittels eines umlaufenden Messers, bei dem der Strang von einer Strangführung gestützt wird, die von einem Antrieb vorzugsweise einem Kurbeltrieb, in eine hin- und hergehende Bewegung versetzt wird, wobei die Unwucht des Kurbeltriebs durch eine mit diesem rotierende erste Ausgleichsmasse teilweise ausgeglichen wird.The invention relates to a method for cutting at least one endless moving strands of the tobacco processing industry into rod-shaped individual articles by means of a rotating knife, in which the strand is guided by a strand is supported by a drive, preferably a crank drive, in a and moving movement is offset, the unbalance of the crank mechanism partially balanced by a first balancing mass rotating with it becomes.

Die Erfindung betrifft außerdem eine Vorrichtung zum Zertrennen mindestens eines endlosen bewegten Stranges der tabakverarbeitenden Industrie in stabförmige Einzelartikel mittels eines umlaufenden Messers, mit mindestens einer von einem Antrieb vorzugsweise einem Kurbeltrieb, synchron zum Messer antreibbaren den Strang stützenden Strangführung, wobei eine Kurbelstange einerseits auf einem exzentrisch zu der Antriebswelle der Kurbel angeordneten Kurbelzapfen gelagert, andererseits mit einer die Strangführung tragenden Stütze verbunden ist, und mit einer ersten umlaufenden Ausgleichsmasse im Bereich der Kurbel oder deren Antriebs.The invention also relates to a device for cutting at least one endless moving strands of the tobacco processing industry in rod-shaped individual articles by means of a rotating knife, with at least one of a drive preferably a crank mechanism that can be driven synchronously with the knife Strand-supporting strand guide, with a crank rod on the one hand Eccentrically mounted to the crankshaft drive shaft, on the other hand is connected to a support carrying the strand guide, and with a first circumferential balancing mass in the area of the crank or its drive.

Mit "stabförmiger Artikel" sind im Sinne der Erfindung sowohl Tabakartikel wie Zigaretten, Zigarren, Zigarillos als auch Filterstäbe oder Filterhülsen gemeint. Im folgenden wird der Einfachheit halber nur noch von Zigaretten gesprochen.For the purposes of the invention, "rod-shaped article" includes both tobacco articles and cigarettes, Cigars, cigarillos as well as filter sticks or filter sleeves are meant. Hereinafter for the sake of simplicity only cigarettes are used.

In Schneidvorrichtungen von Strangmaschinen wird eine endloser in Richtung seiner Längsachse bewegter Zigarettenstrang in Einzelzigaretten zerschnitten. Die Strangführung führt den Zigarettenstrang im Bereich der Schneidvorrichtung und ist an der Schneidstelle als Gegenmesser oder Schneidgegenkante für das umlaufende Messer ausgebildet. Da der Zigarettenstrang sich beim Schnitt weiterbewegt, und zwar bei modernen Strangmaschinen mit sehr hoher Geschwindigkeit, muß die Schneidstelle während des Schnittes mit dem Zigarettenstrang bewegt werden. Aus diesem Grund ist die Strangführung in Strangrichtung bewegbar gelagert und von einem Antrieb, üblicherweise von einem Kurbeltrieb, zu hin- und hergehenden Bewegungen angetrieben.In cutting devices of strand machines, one is endless towards its Longitudinal axis of moving cigarette rod cut into single cigarettes. The Strand guide guides the cigarette rod in the area of the cutting device and is at the cutting point as counter knife or cutting counter edge for the circumferential Knife trained. Since the cigarette rod continues to move when cut, in modern strand machines at very high speed, the Cutting point to be moved with the cigarette rod during the cut. Out for this reason, the strand guide is movably supported in the strand direction and by a drive, usually from a crank drive, to reciprocating movements driven.

Die Strangführung ist als sogenannte Tube ausgebildet, die eine Ausnehmung aufweist, durch die das Messer zum Schneider des Zigarettenstranges hindurchtritt. Sie ist über eine Kurbelstange von dem Kurbeltrieb synchron mit dem Messer angetrieben. Diese bewährte Ausführung macht jedoch bei Leistungssteigerungen der Strangmaschinen, die enorme Produktionsleistungen erbringen (bis zu 16.000 Zigaretten/min.) Probleme. Die relativ großen Massen dieser Antriebsart, deren Unwuchten nur teilweise ausgeglichen werden können, haben große Schwingungen zur Folge, die sich z. B. als Fußbodenschwingungen, verstärkte Körperschallabstrahlung (Lärm) sowie Beeinträchtigung der Funktion benachbarter Baugruppen und/oder elektrotechnischer Komponenten bemerkbar machen. Da die Kurbeldrehachse nicht in der Hauptbewegungsebene der Tuben liegt (und aus konstruktiven und schnittechnischen Gründen dort nicht liegen kann und soll), ist für ein solches Getriebe auf diese Weise prinzipiell kein vollständiger Massenausgleich möglich. Die in die Maschine eingeleiteten Kräfte können aber gegenüber dem nichtausgeglichenen Zustand deutlich reduziert werden.The strand guide is designed as a so-called tube, which has a recess, through which the knife passes to the cutter of the cigarette rod. It is driven by the crank mechanism via a crank rod in synchronism with the knife. However, this proven design makes the Extrusion machines that provide enormous production output (up to 16,000 cigarettes / min.) Problems. The relatively large masses of this type of drive, their unbalance can only be partially compensated, have large vibrations result, which z. B. as floor vibrations, increased structure-borne noise (Noise) and impairment of the function of neighboring assemblies and / or make electrical components noticeable. Because the crank axis of rotation is not in the main plane of movement of the tubes (and from constructive and cutting reasons cannot and should not be there) is for one In principle, transmissions in this way do not allow full mass balancing. The forces introduced into the machine can be compared to the unbalanced ones Condition can be significantly reduced.

Sogenannte "Kurbeltriebe" für die Tuben von Strangmaschinen, die kinematisch zwar im Prinzip viergliedrige Koppelgetriebe darstellen, bei der Verwendung von Schwingen aus einem flexiblen Material und bei ausreichenden Schwingenlängen aber als Kurbeltriebe aufgefaßt werden können, sind in vielfachen Ausführungsformen bekannt, z. B. durch die GB 1 556 267, US 4 534 252 oder DE 2 233 064; sie lösen aber die oben beschriebenen Probleme nur zum Teil.So-called "crank drives" for the tubes of extrusion machines, the kinematic represent in principle four-link coupling gear when using Swing made of a flexible material and with sufficient swing lengths but can be understood as crank drives, are in multiple embodiments known, e.g. B. by GB 1 556 267, US 4 534 252 or DE 2 233 064; she but only partially solve the problems described above.

Die der Erfindung zugrundeliegende Aufgabe besteht darin, die von Kurbeltrieben der eingangs genannten Art ausgehenden Schwingungen so zu beeinflussen, daß die von ihnen ausgehenden schädlichen Kräfte und Momente, einschließlich der Schallabstrahlungen, reduziert werden.The object on which the invention is based is that of crank drives to influence the outgoing vibrations of the type mentioned in such a way that the harmful forces and moments emanating from them, including the Noise emissions can be reduced.

Die Lösung gemäß der Erfindung besteht darin, daß synchron zu der ersten Ausgleichsmasse eine zweite Ausgleichsmasse von einer im Abstand von dem Kurbeltrieb angeordneten Welle zu einer Umlaufbewegung angetrieben wird. Mit "synchron" ist gemeint, daß die zweite Ausgleichsmasse mit der selben Drehzahl wie die erste Ausgleichsmasse umläuft -. Die Drehrichtungen beider Massen sind jedoch entgegengesetzt.The solution according to the invention is that synchronous to the first balancing mass a second balancing mass at a distance from the crank mechanism arranged shaft is driven to a circular motion. With "in sync" is meant that the second balancing mass with the same speed as the first balancing mass circulates -. However, the directions of rotation of both masses are opposite.

Gemäß einer wichtigen Weiterbildung der Erfindung, die erlaubt, die Schwingungen infolge von Unwuchten und damit die von diesen hervorgerufenen Kräfte und Momente auf die Maschine noch weiter zu reduzieren, besteht darin, daß synchron zu der ersten Ausgleichsmasse eine dritte von dem Kurbeltrieb angetriebene Ausgleichsmasse zu einer Umlaufbewegung angetrieben wird.According to an important development of the invention, which allows the vibrations as a result of unbalance and thus the forces and moments caused by them To reduce the machine even further is to synchronize with the first balancing mass, a third balancing mass driven by the crank mechanism is driven to orbit.

Die eingangs genannte Vorrichtung ist dadurch gekennzeichnet, daß eine zweite Ausgleichsmasse vorgesehen ist, die um eine Achse umläuft, die einen Abstand von derjenigen Achse hat, um die die erste Ausgleichsmasse umläuft.The device mentioned at the outset is characterized in that a second Compensating mass is provided, which revolves around an axis that has a distance of the axis around which the first balancing mass rotates.

In Weiterbildung der Erfindung ist die Stütze (Schwinge) als flexibler Träger für die Strangführung ausgebildet. Der Träger kann im wesentlichen aus Blattfedern aus durch Kohlefasern verstärktem Kunststoff bestehen.In a further development of the invention, the support (swing arm) is a flexible support for the Strand guidance trained. The carrier can essentially consist of leaf springs made of carbon fiber reinforced plastic.

Eine bevorzugte Ausgestaltung der Erfindung ist gekennzeichnet durch eine im Abstand von der Antriebswelle der Kurbel angeordnete die zweite Ausgleichsmasse zu synchronen Umläufen antreibende Ausgleichswelle. Die Antriebswelle der Kurbel und die im Abstand davon angeordnete Ausgleichswelle können gemäß der Erfindung mittels eines Riementriebes, vorzugsweise eines Zahnriemens, kinematisch miteinander verbunden sein, wobei darauf zu achten ist, daß die Wellen gegenläufig rotieren. Der Schwerpunkt der zweiten Ausgleichsmasse befindet sich vorteilhaft in einer vertikalen Ebene mit dem Schwerpunkt der ersten Ausgleichsmasse, wenn die Hin- und Herbewegung der Tuben im wesentlichen in einer horizontalen Ebene erfolgt.A preferred embodiment of the invention is characterized by a distance the second balancing mass arranged by the drive shaft of the crank balance shaft driving synchronous revolutions. The crank drive shaft and the balance shaft spaced therefrom can according to the invention kinematically by means of a belt drive, preferably a toothed belt be interconnected, taking care that the waves run in opposite directions rotate. The focus of the second balancing mass is advantageous in a vertical plane with the center of gravity of the first balancing mass if the reciprocation of the tubes essentially in a horizontal plane he follows.

Eine wichtige weitere Ausgestaltung der Erfindung, die zu einer weiteren Verbesserung des Massenausgleichs des Kurbeltriebes führt, besteht darin, daß mit der Antriebswelle der Kurbel eine dritte Ausgleichsmasse kinematisch in Verbindung steht. Die dritte Ausgleichsmasse wird vorteilhaft von der Antriebswelle der Kurbel zu Umläufen angetrieben. Sie ist außerdem vorteilhaft in einem axialen Abstand zu der ersten Ausgleichsmasse und gegenüber dieser verdreht angeordnet.An important further embodiment of the invention, which leads to a further improvement the mass balance of the crank drive leads, is that with the drive shaft the crank is kinematically connected to a third balancing mass. The third balancing mass is advantageous from the drive shaft of the crank Revolutions driven. It is also advantageous at an axial distance from the first balancing mass and rotated relative to this.

Der Kurbeltrieb gemäß der Erfindung mit seinem weitgehenden Massenausgleich ist zum Antrieb einer Strangführung mit einer Führungstube für einen Strang der tabakverarbeitenden Industrie, insbesondere einen Zigarettenstrang, in einer sogenannten Einstrangmaschine geeignet. Eine vorteilhafte Anwendung ist aber auch in sogenannten Zweistrang-Zigarettenherstellmaschinen gegeben, in denen zwei Stränge von zwei Führungstuben geführt sind, die von einer Trägerkonfiguration und einem Kurbeltrieb antreibbar sind, und durch die ein Messer die beiden Stränge zerschneidet.The crank mechanism according to the invention with its extensive mass balance is for driving a strand guide with a guide tube for one strand tobacco processing industry, especially a cigarette rod, in a so-called Single strand machine suitable. An advantageous application is also in so-called two-strand cigarette making machines, in which two Strands of two guide tubes are guided by a carrier configuration and a crank mechanism can be driven, and by means of a knife the two strands cuts.

Die Figuren 1 und 2 zeigen eine Strangführung 1 mit zwei Tuben 2, 3 für jeweils einen Zigarettenstrang 4 bzw. 6, mit einem Antrieb 7 und mit einer Abstützung (Träger) 8 in einer im übrigen nicht weiter dargestellten Zweistrang-Zigarettenherstellmaschine 5, etwa vom in der Zigarettenindustrie bekannten Typ "PROTOS 2" der Anmelderin. Die vorgenannten Bauelemente sind Teile einer Schneidvorrichtung 9, in der bekannten Weise die kontinuierlich gebildeten und zur Schneidvorrichtung bewegten Zigarettenstränge 4, 6 in Strangstücke, nämlich Zigaretten einfacher oder mehrfacher Länge, zerschnitten werden. Die übliche Schneidvorrichtung 9 ist mit einem umlaufenden (Pfeil 13) Gehäuse 12 verkleidet und trägt mindestens ein Messer 14, das kardanisch so gelagert ist, daß das Messer während eines Schneidvorgangs, bei dem es durch Zwischenräume 16 in den Tuben 4, 6 hindurch geführt ist, eine Bewegungskomponente in Förderrichtung der Zigarettenstränge 4, 6 (Pfeil 17) hat -. Die Bewegungskomponente entspricht der Stranggeschwindigkeit. Außerdem wird das Messer während des Schnittes senkrecht zu den den Zigarettensträngen gehalten.Figures 1 and 2 show a strand guide 1 with two tubes 2, 3 for each a cigarette rod 4 or 6, with a drive 7 and with a support (carrier) 8 in a two-strand cigarette manufacturing machine, which is not shown in the rest 5, for example of the type known in the cigarette industry "PROTOS 2" by the applicant. The aforementioned components are part of one Cutting device 9, in the known manner, the continuously formed and Cutting device moved cigarette strands 4, 6 into strands, namely cigarettes single or multiple length, can be cut. The usual cutter 9 is covered with a circumferential (arrow 13) housing 12 and carries at least one knife 14, which is gimbaled so that the knife during a cutting process in which there are spaces 16 in the tubes 4, 6 is passed through, a movement component in the conveying direction of the cigarette strands 4, 6 (arrow 17) has -. The movement component corresponds to the line speed. In addition, the knife becomes perpendicular to during the cut kept the cigarette strands.

Die Tuben 2 und 3 sind mittels eines Tubenhalters 21 an einem Ende 18 der Abstützung 8 (auch Schwinge genannt) befestigt, die drei Blattfedern 22, 23 und 24 aus kohlefaserverstärktem Kunstharz (z. B. Eproxidharz) aufweist. Die Blattfedern 22, 23 lassen einen Zwischenraum 26 zwischen sich frei, durch die eine Kurbelstange 27 (Pleuel) eines Kurbeltriebs 7 für die Tuben 2 und 3 hindurch greift, die an ihrem einen Ende 28 auf einem Zapfen 29 im Tubenhalter 21 gelagert ist. Die Blattfeder 24 ist den Blattfedern 22, 23 gegenüber angeordnet. Alle Blattfedern sind an ihrem dem Tubenhalter 21 abgewandten Ende 31 an einem Blattfederhalter 32 befestigt.The tubes 2 and 3 are by means of a tube holder 21 at one end 18 of the support 8 (also called swing arm) attached, the three leaf springs 22, 23 and 24 made of carbon fiber reinforced synthetic resin (e.g. epoxy resin). The leaf springs 22, 23 leave a space 26 between them, through which a crank rod 27 (connecting rod) of a crank mechanism 7 for the tubes 2 and 3, which engages one end 28 is mounted on a pin 29 in the tube holder 21. The Leaf spring 24 is arranged opposite the leaf springs 22, 23. All leaf springs are at its end 31 facing away from the tube holder 21 on a leaf spring holder 32 attached.

Die Kurbelstange 27 des Kurbeltriebs 7 ist mit ihrem anderen Ende 33 auf einem Kurbelzapfen 34 einer Kurbel 36 gelagert. Der Kurbelzapfen 34 ist exzentrisch zu einer von einem Motor 38 angetriebenen Antriebswelle 37 mit der Drehachse 40 der Kurbel 36 angeordnet. Die Kurbel 36 ist mit einer sogenannten ersten Ausgleichsmasse 41 versehen, die einen Teil der Massenkräfte erster Ordnung reduziert. Da die Kurbeldrehachse nicht in der Hauptbewegungsebene der Tuben liegt und aus konstruktiven und schnittechnischen Gründen dort nicht liegen kann und soll, ist für das Getriebe auf diese Weise kein besonders guter Massenausgleich möglich.The other end 33 of the crank rod 27 of the crank mechanism 7 is on one Crank pin 34 of a crank 36 mounted. The crank pin 34 is eccentric too a drive shaft 37 driven by a motor 38 with the axis of rotation 40 of the Crank 36 arranged. The crank 36 is with a so-called first balancing mass 41 provided that reduces part of the first order mass forces. There the crank axis of rotation is not in the main plane of movement of the tubes and from constructive and cutting reasons cannot and should not be there for the transmission is not particularly good in this way.

Um den Massenausgleich des Tubentriebs zu verbessern wird gemäß der Erfindung eine zweite Ausgleichsmasse 42 vorgesehen, deren Schwerpunkt 45 einen bestimmten Abstand x von der Drehachse 43 einer Welle 44 (Ausgleichswelle) hat, die die zweite Ausgleichsmasse 42 zu Umläufen antreibt. Der Schwerpunkt der zweiten Ausgleichsmasse 42 liegt vorteilhaft in der Ebene des Schwerpunktes der auf der Kurbel 36 befindlichen ersten Ausgleichsmasse 41. Bei horizontal geführten Tuben handelt es sich dabei um eine vertikale Ebene, in der die Schwerpunkte der Ausgleichsmassen liegen. Die Wellen 44 und 37 sind, z. B. mittels eines Zahnriemens 46, kinematisch derart miteinander verbunden, daß sie synchron umlaufen. d. h. gleich Drehzahlen haben -. Ihre Drehrichtungen sind gegensinnig. Mit 39 ist eine Zahnscheibe zum Umlenken des Zahnriemens 46 bezeichnet. Mit dieser zweiten Ausgleichsmasse 42 können die nach dem teilweisen Massenausgleich mit Hilfe der ersten Ausgleichsmasse 41 verbleibenden Massenkräfte zusätzlich deutlich reduziert werden. Dies gilt auch für die in die Maschine und den Fußboden eingeleiteten Massenmomente.In order to improve the mass balance of the tube drive according to the invention a second balancing mass 42 is provided, the center of gravity 45 of which has a certain distance x from the axis of rotation 43 of a shaft 44 (balance shaft), which drives the second balancing mass 42 to circulate. The focus of the second balancing mass 42 is advantageously in the plane of the center of gravity first balancing mass 41 located on the crank 36 Tubes are a vertical plane in which the focus of the Compensating masses. The shafts 44 and 37 are e.g. B. by means of a toothed belt 46, kinematically connected to one another in such a way that they circulate synchronously. d. H. have equal speeds -. Their directions of rotation are opposite. At 39 is one Toothed pulley for deflecting the toothed belt 46. With this second Compensating mass 42 can with the help of the partial mass balancing of the first balancing mass 41, the remaining inertial forces are also significant be reduced. This also applies to those introduced into the machine and the floor Mass moments.

Gemäß der Erfindung kann der Massenausgleich noch weiter verbessert werden durch eine dritte Ausgleichsmasse 48, die von der Antriebswelle 37 der Kurbel 36 zu Umlaufbewegungen angetrieben wird. Die dritte Ausgleichsmasse 48 ist in einem axialen Abstand von der ersten Ausgleichsmasse 41 angeordnet und weist eine von dieser abweichende Winkellage auf. According to the invention, the mass balance can be further improved by a third balancing mass 48, which is driven by the drive shaft 37 of the crank 36 is driven to orbital movements. The third balancing mass 48 is in one arranged axially distance from the first balancing mass 41 and points an angular position deviating from this.

Bei einem Antrieb der Schneidvorrichtung 9 durch den Motor 38 führt die Kurbelstange 27 des Kurbeltriebs 7 hin- und hergehende Bewegungen entsprechend Doppelpfeil 49 aus. Die Tuben 2 und 3 führen entsprechende hin- hergehende Linearbewegungen aus. Während der Linearbewegung der Tuben in Bewegungsrichtung 17 der Zigarettenstränge 4 und 6 wird zu diesem Zeitpunkt das Messer 14 ebenfalls in Richtung 17 bewegt und zusätzlich durch den Freiraum 16 in den Tuben 2 und 3 hindurchgeführt, wobei es einen Trennschnitt durch die Stränge ausführt.When the cutting device 9 is driven by the motor 38, the crank rod guides 27 of the crank mechanism 7 back and forth movements accordingly Double arrow 49 off. Tubes 2 and 3 have corresponding linear movements out. During the linear movement of the tubes in the direction of movement 17 of the cigarette strands 4 and 6 becomes the knife 14 at this time also moved in direction 17 and additionally through the free space 16 in the tubes 2 and 3 passed, making a separating cut through the strands.
