Description

Die Erfindung betrifft eine Vorrichtung zum Ändern des längsaxialen Abstandes von paarweise koaxial zueinander ausgerichteten, in zwei benachbarten Reihen queraxial längs einer Förderstrecke geförderten stabförmigen Artikeln der tabakverarbeitenden Industrie, mit am Außenumfang Haltemulden aufweisenden Fördertrommeln zum Zuführen und Abführen der benachbarten Artikelreihen sowie mit wenigstens im Bereich einer der beiden Artikelreihen mit den Fördertrommeln zusammenwirkenden und Haltemulden aufweisenden Spreizmitteln.The invention relates to a device for changing the longitudinal axial distance of pairs of coaxially aligned rod-shaped articles of the tobacco processing industry, which are conveyed in two adjacent rows transversely along a conveying path, with conveying drums on the outer circumference having troughs for feeding and discharging the neighboring rows of articles, and at least in the area of one of the two series of articles interacting with the spreading drums and having holding troughs.

Vorrichtungen der vorstehend bezeichneten Art werden zum Beispiel in Maschinen zum Herstellen von Zigaretten bzw. Filterzigaretten eingesetzt, die nach der Trennung von doppeltlangen Filterzigaretten in Filterzigaretten einfacher Länge doppelbahnig in der genannten Formation und Ausrichtung die Maschine durchlaufen und beispielsweise zwecks getrennter Inspektion auf zwei Bahnen axial separiert bzw. auf gespreizten Bahnen derartigen Prüfeinrichtungen zugeführt werden sollen.
Eine weitere Einsatzmöglichkeit wäre das Spreizen von geschnittenen doppeltlangen Tabakstöcken, zwischen die ein doppeltlanger Filterstab eingefügt und mit den Tabakstöcken verbunden werden soll.Devices of the type described above are used, for example, in machines for producing cigarettes or filter cigarettes which, after the separation of double-length filter cigarettes into filter cigarettes of simple length, pass through the machine in double lanes in the above-mentioned formation and orientation and are separated axially, for example, for separate inspection on two lanes or to be supplied to such test facilities on spread paths.
Another possible application would be the spreading of cut double-length tobacco sticks, between which a double-length filter rod is to be inserted and connected to the tobacco sticks.

Eine durch die DE-OS 38 17 740 bekanntgewordene Einrichtung der genannten Gattung weist zur axialen Verschiebung von Zigaretten jeweils für eine zu separierende Reihe zwei relativ platzaufwendige konische Trommeln mit entgegengerichteter Konizität auf.A device of the type mentioned, which became known from DE-OS 38 17 740, has two relatively space-consuming conical drums with opposite conicity for the axial displacement of cigarettes for each row to be separated.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der oben bezeichneten Art weiter zu verbessern.The invention has for its object to further improve a device of the type described above.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Spreizmittel als Parallelscheibenantrieb ausgebildet sind, welcher geneigt zu den Drehachsen der Fördertrommeln angeordnet ist und dessen Haltemulden an den Enden von Antriebszapfen des Parallelscheibenantriebs angeordnet sind.
Die Konstruktion ist so getroffenen, daß die Antriebszapfen parallel zueinander sowie zu den Achsen der Fördertrommeln ausgerichtet sind.
Erreicht wird dies nach einer Weiterbildung dadurch, daß der Parallelscheibenantrieb zwei um exzentrisch zueinander versetzte Drehachsen umlaufende Antriebsscheiben aufweist, wobei gemäß einer Weiterbildung eine der Antriebsscheiben des Parallelscheibenantriebs einen zentralen Antrieb aufweist und mit der anderen Antriebsscheibe über die exzentrisch angeordneten Antriebszapfen verbunden ist.
Zweckmäßigerweise sind die Antriebszapfen als drehgelenkig in den Antriebsscheiben gelagerte Kurbelzapfen ausgebildet, wobei nach einem zusätzlichen Vorschlag jede Haltemulde einem Muldenträger zugeordnet ist, den ein entsprechender Kurbelzapfen mittels einer Drehlagerung aufnimmt.
Um eine stabile Außenlage der Haltemulden in der jeweiligen Übergabestellung mit der die Artikel zufördernden Trommel sowie die Artikel abfördernden Trommel zu gewährleisten, sieht eine bevorzugte Ausgestaltung vor, daß die Drehlagerung des Muldenträgers zugleich ein Lager des Kurbelzapfens bildet, das von einer peripheren Ausnehmung einer Antriebsscheibe drehgesichert, längsverschiebbar aufgenommen wird.
Mit alternativen Mitteln wird die stabile Ausrichtung der Haltemulden dadurch erreicht, daß die Muldenträger mit separaten, eine relative Längsverschiebung zulassenden Drehsicherungsmitteln versehen sind.
Diese Drehsicherungsmittel sind zweckmäßigerweise als jeweils paarweise zwei Muldenträger in der Außenlage der Haltemulden gegeneinander verriegelnde Verdrehsperre ausgebildet.This object is achieved in that the expansion means are designed as a parallel disk drive, which is arranged inclined to the axes of rotation of the conveyor drums and the holding troughs are arranged at the ends of drive pins of the parallel disk drive.
The construction is such that the drive pins are aligned parallel to one another and to the axes of the conveyor drums.
According to a further development, this is achieved in that the parallel pulley drive has two drive pulleys rotating around eccentrically offset axes of rotation, whereby according to a further development one of the drive pulleys of the parallel pulley drive has a central drive and is connected to the other drive pulley via the eccentrically arranged drive pins.
The drive pins are expediently designed as pivot pins mounted in the drive disks, whereby according to an additional proposal, each holding trough is assigned to a trough carrier which a corresponding crank pin receives by means of a rotary bearing.
In order to ensure a stable outer position of the holding troughs in the respective transfer position with the drum supplying the article and the article conveying drum, a preferred embodiment provides that the pivot bearing of the trough carrier at the same time forms a bearing of the crank pin, which is secured against rotation by a peripheral recess of a drive disk , is slidably received.
With alternative means, the stable alignment of the holding troughs is achieved in that the trough supports are provided with separate anti-rotation means which allow a relative longitudinal displacement.
These anti-rotation means are expediently designed as pairs of two trough carriers in the outer position of the holding troughs which lock against one another rotation lock.

Eine weiter vereinfachte Variante des erfindungsgemäßen Antriebskonzeptes besteht darin, daß eine Antriebsscheibe des Parallelscheibenantriebs eine kardanische Lagerung aufweist und mittels eines Querbolzen-Drehgelenkes mit einer zentralen Antriebswelle sowie am Außenumfang durch Querbolzen-Drehgelenke mit den Antriebszapfen verbunden ist, welche einerseits fest mit den Muldenträgern verbunden und andererseits in der zweiten Antriebsscheibe drehgelenkig gelagert sind.
Eine problemlose Saugluftverbindung zu den Haltemulden der Antriebsscheibe wird nach einer speziellen Ausgestaltung dadurch gewährleistet, daß die Drehgelenkverbindung als sphärisches Lager ausgebildet ist.
Eine weitere Vereinfachung des Parallelscheibenantriebs wird dadurch erreicht, daß die geneigten Antriebsscheiben um eine einzige gemeinsame Achse antreibbar sind.A further simplified variant of the drive concept according to the invention is that a drive pulley of the parallel pulley drive has a cardanic bearing and is connected to the central drive shaft by means of a transverse pin swivel joint and on the outer circumference by transverse pin swivel joints to the drive pin, which on the one hand is firmly connected to the trough supports and on the other hand, are pivotally mounted in the second drive disk.
A problem-free suction air connection to the holding troughs of the drive pulley is ensured according to a special embodiment in that the swivel connection is designed as a spherical bearing.
A further simplification of the parallel disk drive is achieved in that the inclined drive disks can be driven about a single common axis.

Der erfindungsgemäße Aufbau sorgt ohne translatorische Gleitbewegungen oder Rollbewegungen auf Kurven dafür, daß die Haltemulden in jeder Drehstellung der Spreizmittel immer zu sich selber parallel stehen. Wegen Fehlens translatorisch bewegter Teile werden Schwingungen vermieden sowie ein verschleißarmer Betrieb einer kompakt ausgebildeten Vorrichtung gewährleistet.The construction according to the invention ensures, without translatory sliding movements or rolling movements on curves, that the holding troughs are always parallel to themselves in every rotational position of the spreading means. Due to the lack of translationally moving parts, vibrations are avoided and low-wear operation of a compact device is ensured.

Die Erfindung wird nachstehend anhand von in den beigefügten Abbildungen dargestellten unterschiedlichen Ausführungsbeispielen näher erläutert.The invention is explained in more detail below on the basis of different exemplary embodiments illustrated in the attached figures.

Die in Figur 1 dargestellten Spreizmittel sind als Parallelscheibenantrieb 1 ausgebildet und einer Trommelanordnung zugeordnet, bestehend aus einer um eine Achse 2 drehende Fördertrommel 3 zum Heranführen von zwei parallelen Reihen 4 und 5 von quer zu ihren Längsachsen geförderten sowie paarweise koaxial zueinander ausgerichteten Filterzigaretten 6, einer um eine Achse 7 drehende Fördertrommel 8 zur Übernahme und Weiterförderung der Filterzigarettenreihe 4 sowie einer um eine Achse 9 drehende Fördertrommel 10 zum Übernehmen der Filterzigarettenreihe 4 sowie der dieser gegenüber auf Abstand gebrachten Filterzigarettenreihe 5.
Die Fördertrommeln 3, 8 und 10 sind am Umfang mit Haltemulden 11 für die Filterzigaretten 6 versehen, deren gesteuerte Halteluftbohrungen 12 mit Saugluftkammern 13 von stationären Trommelkörpern 14 bzw. 15 bzw. 16 verbindbar sind, um welche die Fördertrommeln 3 bzw. 8 bzw. 10 jeweils rotieren. Als Antriebsmittel für die zentrale Zwischenfördertrommel 8 dient ein Zahnrad 17, während die Antriebsmittel für die Fördertrommeln 3 und 10 aus mit dem Zahnrad 17 kämmenden Zahnrädern 17a und 17b bestehen.
Der Parallelscheibenantrieb 1 zum Spreizen der rechten Filterzigarettenreihe 5 während der Überführung von der Fördertrommel 8 auf die Fördertrommel 10 weist zwei parallele sowie exzentrisch zueinander versetzte Antriebsscheiben 18 und 19 auf, deren parallele Drehachsen 20 und 21 geneigt zu den Achsen 2, 7 und 9 der Fördertrommeln 3 bzw. 8 bzw. 10 verlaufen. Die innere Antriebsscheibe 19 ist mittels eines Zahnrades 22 durch dessen stirnseitige Hirth-Verzahnung 23 antreibbar, während die äußere Antriebsscheibe 18 über Antriebskurbeln 24 von der inneren Antriebsscheibe 19 mitgenommen wird. Die in den Antriebsscheiben 18 und 19 drehbeweglich gelagerten parallelen Antriebskurbeln 24 tragen an ihren freien Antriebszapfen 25 Muldenträger 26 für die Haltemulden 11 des Parallelscheibenantriebs 1. Die äußeren Lagerkörper 27 der Muldenträger 26 bzw. der Drehlager der Antriebskurbeln 24 innerhalb der Antriebsscheibe 19 werden maulschlüsselartig derart von peripheren, langlochartigen Ausnehmungen 28 der Antriebsscheibe 19 aufgenommen, daß sie verdrehgesichert aber während des Umlaufs der Antriebsscheibe 19 auf ihrer kegelförmigen Bahn längsverschieblich in den Ausnehmungen 28 geführt sind. Auf diese Weise werden die Haltemulden 11 der während ihres Umlaufs parallel zu sich selbst sowie parallel zu den Achsen 2, 7, 9 der Fördertrommeln 3 bzw. 8 bzw. 10 geführten Muldenträger 26 immer in einer stabilen Außenlage gehalten, in der sie Filterzigaretten 6 der Reihe 5 von der Fördertrommel 3 übernehmen, während ihres Umlaufes auf der Kegelbahn der Antriebsscheibe 19 spreizen, d. h. gegenüber der durchlaufenden Reihe 4 auf Abstand bringen und auf die Fördertrommel 10 mit einem definierten Abstand zur Reihe 4 der Filterzigaretten übergeben. Hierzu sind auch die Muldenträger 26 zur Beaufschlagung der Haltemulden mit Saugluft mit entsprechenden Saugluftkammern 13 versehen, welche über die hohl gestalteten Antriebskurbeln 24 mit einem stationären Steuerkörper 29 verbunden sind.The expanding means shown in Figure 1 are designed as a parallel disk drive 1 and assigned to a drum arrangement, consisting of a conveyor drum 3 rotating about an axis 2 for bringing two parallel rows 4 and 5 of filter cigarettes 6, which are conveyed transversely to their longitudinal axes and are aligned coaxially to one another in pairs Conveyor drum 8 rotating about an axis 7 for taking over and further conveying the row of filter cigarettes 4 and a conveying drum 10 rotating about an axis 9 for taking over the row of filter cigarettes 4 and the row of filter cigarettes 5 spaced apart.
The conveyor drums 3, 8 and 10 are provided on the circumference with holding troughs 11 for the filter cigarettes 6, the controlled holding air bores 12 of which can be connected to suction air chambers 13 of stationary drum bodies 14 or 15 or 16, around which the conveyor drums 3 or 8 or 10 rotate each. A gear 17 serves as the drive means for the central intermediate conveyor drum 8, while the drive means for the conveyor drums 3 and 10 consist of gear wheels 17a and 17b which mesh with the gear 17.
The parallel disk drive 1 for spreading the right row of filter cigarettes 5 during the transfer from the conveyor drum 8 to the conveyor drum 10 has two parallel and eccentrically offset drive disks 18 and 19, the parallel axes of rotation 20 and 21 of which are inclined to the axes 2, 7 and 9 of the conveyor drums 3 or 8 or 10 run. The inner drive pulley 19 can be driven by means of a gearwheel 22 through its front Hirth toothing 23, while the outer drive pulley 18 is driven by the inner drive pulley 19 via drive cranks 24. The parallel drive cranks 24, which are rotatably mounted in the drive disks 18 and 19, carry on their free drive pins 25 trough supports 26 for the holding troughs 11 of the parallel disk drive 1. The outer bearing bodies 27 of the trough supports 26 and the Rotary bearings of the drive cranks 24 within the drive pulley 19 are held in a wrench-like manner by peripheral, slot-like recesses 28 of the drive pulley 19 in such a way that they are secured against rotation during the rotation of the drive pulley 19 on their conical path in the recesses 28 so as to be longitudinally displaceable. In this way, the holding troughs 11 of the trough carriers 26, which are guided parallel to themselves and parallel to the axes 2, 7, 9 of the conveying drums 3, 8 and 10, are always held in a stable outer position in which they hold filter cigarettes 6 Take row 5 from the conveyor drum 3, spread during their circulation on the bowling lane of the drive pulley 19, ie bring them apart from the continuous row 4 and transfer them to the conveyor drum 10 at a defined distance from the row 4 of the filter cigarettes. For this purpose, the trough carriers 26 are also provided with corresponding suction air chambers 13 for supplying suction air to the holding troughs, which suction chambers are connected to a stationary control body 29 via the hollow drive cranks 24.

Bei dem in Figur 2 dargestellten abgewandelten Ausführungsbeispiel sind Teile die denen des Ausführungsbeispiels gemäß Figur 1 entsprechen mit um hundert erhöhten Bezugszahlen versehen und nicht noch einmal besonders erläutert.
Bei dieser Variante erfolgt der direkte zentrale Antrieb durch ein Zahnrad 130 und Kegelräder 131 auf die äußere Antriebsscheibe 118. Über die Antriebskurbeln 124 wird die innere Antriebsscheibe 119 von der Antriebsscheibe 118 angetrieben. Bei dieser Ausführung nehmen die Antriebszapfen 125 der Antriebskurbeln 124 die Muldenträger 126 drehbeweglich über separate Lagerkörper 132 auf, während die Lagerkörper 127 ausschließlich der Lagerung der Antriebskurbeln in der inneren Antriebsscheibe 119 dienen. Um die Haltemulden 111 während ihres Umlaufes um 180° in einer stabilen Außenlage zu halten, sind gemäß Figur 3a jeweils zwei Muldenträger 126 mittels einer Gleitnase 133 gegeneinander drehgesichert, wobei an der Antriebsscheibe 119 befestigte und an den Innenseiten der Muldenträger 126 angreifende Zugfedern 124 die Muldenträger 126 so um ihren Antriebszapfen 125 verdrehen, daß die Gleitnase einerseits als Verdrehsperre wirkt, hingegen eine Relativverschiebung in Längsrichtung des Antriebszapfens 125 zuläßt.
In den Figuren 3b bis 3d sind abgewandelte Ausführungsformen von Drehsicherungsmitteln für die Muldenträger 126 dargestellt. Gemäß Figur 3b wird der Kraftschluß der Gleitnase 133 dadurch erzeugt, daß zwei Permanentmagneten 135 die Muldenträger 126 paarweise an der Gleitnase 133 zur Anlage bringen.
Gemäß Figur 3c wird eine stabile Lage der Muldenträger 126 durch eine als Verdrehsperre wirkende Klauenverbindung 136 erzielt, wobei Zugfedern 137 die Muldenträger 126 ruhig halten.In the modified exemplary embodiment shown in FIG. 2, parts which correspond to those of the exemplary embodiment according to FIG. 1 are provided with reference numbers increased by a hundred and are not explained again in particular.
In this variant, the direct central drive is effected by a gear 130 and bevel gears 131 on the outer drive pulley 118. The inner drive pulley 119 is driven by the drive pulley 118 via the drive cranks 124. In this embodiment, the drive pins 125 of the drive cranks 124 receive the trough carriers 126 in a rotatable manner via separate bearing bodies 132, while the bearing bodies 127 serve exclusively to mount the drive cranks in the inner drive disk 119. In order to keep the holding troughs 111 in a stable outer position during their rotation through 180 °, according to FIG Two trough supports 126 are secured against rotation against each other by means of a sliding lug 133, tension springs 124 fastened to the drive disk 119 and acting on the inner sides of the trough supports 126 twisting the trough supports 126 about their drive journal 125 such that the sliding nose acts on the one hand as a rotation lock, on the other hand a relative displacement in the longitudinal direction of the drive pin 125.
FIGS. 3b to 3d show modified embodiments of anti-rotation means for the trough carrier 126. According to FIG. 3b, the frictional connection of the sliding lug 133 is produced in that two permanent magnets 135 bring the trough carriers 126 into contact with the sliding lug 133 in pairs.
According to FIG. 3c, a stable position of the trough carriers 126 is achieved by means of a claw connection 136 which acts as an anti-rotation lock, tension springs 137 keeping the trough carriers 126 still.

Gemäß Figur 3d sind jeweils zwei Muldenträger 126 mittels eines als Verdrehsperre wirkenden Federdrahtes 138 verbunden.According to FIG. 3d, two trough carriers 126 are each connected by means of a spring wire 138 which acts as a twist lock.
