- Such a cigarette packaging machine is known from GB-A-2 017 032, in which the drivers of the conveyor chain for taking a block of cigarettes out of a cell of the revolver hit the cigarettes located in the cell to be emptied when the revolver comes to a standstill at the conveyor chain speed.
- the cigarettes are first pushed against a comb-like stop plate in order to be aligned with one another in terms of length.
- the stop plate then initially moves in the direction of conveyance and finally dips away to clear the conveying path.
- the greater the speed of the conveyor chain the more the cigarettes are stressed by the driver and the stop plate, so that the sensitive cigarettes are not treated with sufficient care at high packaging speeds.
- the block-shaped objects to be packaged are picked up by cells from individual conveying devices, such as revolvers, conveyor chains or the like, in order to carry out the individual packaging processes or to carry them on or off.
- individual conveying devices such as revolvers, conveyor chains or the like
- the carriers for taking over the respective cells of the revolver the carriers hit the objects to be taken over, located in the revolver cells, with the conveying speed of the conveyor chain . Since cigarette blocks, inner packets, freshly glued cigarette packs, etc. are relatively sensitive objects, such handling often leads to damage or malfunctions, especially at higher speeds of the conveyor chain.
- the object of the invention is to provide a cigarette packaging machine of the type mentioned, which makes it possible to transfer the block-shaped objects between the cells of a revolver and a continuously driven conveyor chain gently for the objects to be transferred, even at a high rotational speed of the conveyor chain.
- the cells of the turret are arranged so as to be displaceable in the axial direction and can be coupled in the transfer position to a slide which accelerates the respective cell in the conveying direction of the conveyor chain in such a way that the cell reaches the object to be picked up which is in the cell practically has the speed of the conveyor chain due to the driver.
- the proposed axial mobility of the cells of the revolver makes it possible to bring the cells with the block-shaped objects to be transferred therein, in the transfer position of the revolver, essentially to the advance speed of the chain conveyor, so that the drivers of the chain conveyor practically have no relative speed to the ones to be transferred Objects hit them and push them out of the cells of the revolver in the axial direction due to their own advance and the slowing down of the speed of the cells of the revolver.

- the cells 2 each have a slot 20 so that the driver arm 17 can guide the driver plate 18 through the cell 2, which is open in the axial direction.
- the driver plate arrives 18 in engagement with the object 19 to be taken over practically without relative speed between them, so that the impact of the driver plate 18 on the object 19 takes place gently for the latter. Since the cell 2 is decelerated to zero on its further path in the conveying direction of the chain conveyor 10, the driver 16 then pushes the object 19 out of the cell 2 overhauled by it. The latter is then moved back into its starting position by the crank mechanism 15, so that when the turret 1 is indexed, its guide rollers 9 come into engagement with the guide disk 8.
- the turret 1 can also be continuously rotating, but then the cells 2 are to be fastened with their guide rods 6 to pivot levers which are cam-controlled in such a way that the cells 2 are pivoted into the transfer area before reaching the transfer position and during one for the transfer are held in this position for a sufficiently long period of time so that the cells 2 are kept practically stationary despite the continuous rotation of the turret 1 during the transfer position, as described in patent application P 39 43 086.3.

Description
Die Erfindung betrifft eine Zigarettenverpackungsmaschine mit wenigstens einem jeweils einen axialen Schlitz besitzende Zellen aufweisenden Revolver und einer dem Revolver nachgeschalteten, Mitnehmer aufweisenden, kontinuierlich antreibbaren, in Axialrichtung des Revolvers fördernden Förderkette, deren Mitnehmer durch eine jeweilige, in Übergabestellung befindliche Zelle des Revolvers hindurchführbar sind.The invention relates to a cigarette packaging machine with at least one turret, each having an axial slot, and a turret connected downstream of the turret, having drivers, continuously drivable, in the axial direction of the turret, conveyor chain, the drivers of which can be passed through a respective turret cell in the transfer position.
Aus der GB-A-2 017 032 ist eine derartige Zigarettenverpackungsmaschine bekannt, bei der die Mitnehmer der Förderkette zum Mitnehmen eines Zigarettenblocks aus einer Zelle des Revolvers bei dessen Stillstand mit der Fördergeschwindigkeit der Förderkette auf die in der zu entleerenden Zelle befindlichen Zigaretten auftreffen. Hierbei werden die Zigaretten zunächst gegen eine kammartige Anschlagplatte geschoben, um miteinander längenmäßig ausgerichtet zu werden. Die Anschlagplatte bewegt sich dann zunächst in Förderrichtung mit und taucht schließlich weg, um den Förderweg freizugeben. Je größer die Geschwindigkeit der Förderkette ist, um so mehr werden die Zigaretten durch den Mitnehmer und die Anschlagplatte beansprucht, so daß sich bei hohen Verpackungsgeschwindigkeiten keine genügend schonende Behandlung der empfindlichen Zigaretten ergibt.Such a cigarette packaging machine is known from GB-A-2 017 032, in which the drivers of the conveyor chain for taking a block of cigarettes out of a cell of the revolver hit the cigarettes located in the cell to be emptied when the revolver comes to a standstill at the conveyor chain speed. Here, the cigarettes are first pushed against a comb-like stop plate in order to be aligned with one another in terms of length. The stop plate then initially moves in the direction of conveyance and finally dips away to clear the conveying path. The greater the speed of the conveyor chain, the more the cigarettes are stressed by the driver and the stop plate, so that the sensitive cigarettes are not treated with sufficient care at high packaging speeds.
Bei Zigarettenverpackungsmaschinen werden die zu verpackenden, blockförmigen Gegenstände, wie Zigarettenblöcke, Innenpakete, fertige Zigarettenpäckchen etc., von Zellen von einzelnen Fördereinrichtungen, wie Revolvern, Förderketten oder dergleichen, aufgenommen, um die einzelnen Verpackungsvorgänge vorzunehmen bzw. einen Weiter- bzw. Abtransport vorzunehmen. Bei der Übernahme von Gegenständen aus den Zellen eines Revolvers durch eine kontinuierlich umlaufende, Mitnehmer aufweisende Förderkette, wobei die Mitnehmer zur Übernahme die jeweiligen Zellen des Revolvers durchlaufen, treffen die Mitnehmer mit der Fördergeschwindigkeit der Förderkette auf die zu übernehmenden, in den Revolverzellen befindlichen Gegenstände auf. Da Zigarettenblöcke, Innenpakete, frisch verklebte Zigarettenpäckchen usw. relativ empfindliche Gegenstände sind, führt eine derartige Handhabung häufig zu Beschädigungen bzw. Betriebsstörungen, und zwar insbesondere bei höheren Umlaufgeschwindigkeiten der Förderkette.In the case of cigarette packaging machines, the block-shaped objects to be packaged, such as cigarette blocks, inner packs, finished cigarette packs, etc., are picked up by cells from individual conveying devices, such as revolvers, conveyor chains or the like, in order to carry out the individual packaging processes or to carry them on or off. When objects are taken from the cells of a revolver by a continuously rotating conveyor chain, the carriers for taking over the respective cells of the revolver, the carriers hit the objects to be taken over, located in the revolver cells, with the conveying speed of the conveyor chain . Since cigarette blocks, inner packets, freshly glued cigarette packs, etc. are relatively sensitive objects, such handling often leads to damage or malfunctions, especially at higher speeds of the conveyor chain.
Zwar ist es aus der DE-A-3 046 065 bekannt, einen Revolver mit axial verschiebbaren Zellen auszurüsten. Hierbei handelt es sich um einen Kopfschließrevolver, also einen Revolver, auf dem die ansonsten fertigen Zigarettenpäckchen noch kopfseitig geschlossen werden. Dieser Revolver übernimmt das noch kopfseitige offene Päckchen von einem vorhergehenden Revolver durch axiales Überschieben während des Stillstandes der schrittweise umlaufenden Revolver. Die kopfseitig noch offenen Päckchen besitzen aber einen entsprechenden Papier- bzw. Folienüberstand, der aus dem Bereich des vorhergehenden Revolvers wegbewegt werden muß. Letzteres geschieht durch axiales Verschieben der Zellen des Kopfschließrevolvers. Außerhalb des Übergabebereichs zum Kopfschließrevolver befinden sich dessen Zellen jedoch in ihrer axialen Ausgangsposition.It is known from DE-A-3 046 065 to equip a revolver with axially displaceable cells. This is a head-closing revolver, i.e. a revolver, on which the otherwise finished packets of cigarettes are still closed on the head side. This revolver does it still open-sided packages from a previous revolver by axially pushing them over while the revolving revolvers are rotating. The packages still open at the top, however, have a corresponding paper or film protrusion that must be moved away from the area of the previous revolver. The latter is done by axially shifting the cells of the turret. Outside the transfer area to the head locking revolver, however, its cells are in their axial starting position.
Aufgabe der Erfindung ist es, eine Zigarettenverpackungsmaschine der eingangs genannten Art zu schaffen, die es ermöglicht, eine Übergabe der blockförmigen Gegenstände zwischen den Zellen eines Revolvers und einer kontinuierlich angetriebenen Förderkette auch bei hoher Umlaufgeschwindigkeit der Förderkette schonend für die zu übergebenden Gegenstände vorzunehmen.The object of the invention is to provide a cigarette packaging machine of the type mentioned, which makes it possible to transfer the block-shaped objects between the cells of a revolver and a continuously driven conveyor chain gently for the objects to be transferred, even at a high rotational speed of the conveyor chain.
Diese Aufgabe wird dadurch gelöst, daß die Zellen des Revolvers in Axialrichtung verschiebbar angeordnet und in der Übergabestellung mit einem Schieber koppelbar sind, der die jeweilige Zelle in Förderrichtung der Förderkette derart beschleunigt, daß die Zelle beim Erreichen des in der Zelle befindlichen, zu übernehmenden Gegenstandes durch den Mitnehmer praktisch die Geschwindigkeit der Förderkette besitzt.This object is achieved in that the cells of the turret are arranged so as to be displaceable in the axial direction and can be coupled in the transfer position to a slide which accelerates the respective cell in the conveying direction of the conveyor chain in such a way that the cell reaches the object to be picked up which is in the cell practically has the speed of the conveyor chain due to the driver.
Die vorgesehene axiale Beweglichkeit der Zellen des Revolvers ermöglicht es, die Zellen mit den darin befindlichen, zu übergebenden blockförmigen Gegenständen in der Übergabeposition des Revolvers im wesentlichen auf die Vorschubgeschwindigkeit des Kettenförderers zu bringen, so daß die Mitnehmer des Kettenförderes praktisch ohne Relativgeschwindigkeit zu den zu übergebenden Gegenständen auf diese auftreffen und diese aus den Zellen des Revolvers aufgrund des eigenen Vorschubs und der Verlangsamung der Geschwindigkeit der Zellen des Revolvers in Axialrichtung ausschieben.The proposed axial mobility of the cells of the revolver makes it possible to bring the cells with the block-shaped objects to be transferred therein, in the transfer position of the revolver, essentially to the advance speed of the chain conveyor, so that the drivers of the chain conveyor practically have no relative speed to the ones to be transferred Objects hit them and push them out of the cells of the revolver in the axial direction due to their own advance and the slowing down of the speed of the cells of the revolver.
Weitere Ausgestaltungen der Erfindung sind der nachfolgenden Beschreibung und den Unteransprüchen zu entnehmen.Further refinements of the invention can be found in the following description and the subclaims.
Die Erfindung wird nachstehend anhand des in den beigefügten Abbildungen dargestellten Ausführungsbeispiels näher erläutert.The invention is explained below with reference to the embodiment shown in the accompanying figures.
Fig. 1 zeigt ausschnittweise und schematisch einen Revolver und eine Förderkette einer Zigarettenverpackungsmaschine.1 shows a section and schematically of a revolver and a conveyor chain of a cigarette packaging machine.
Fig. 2 zeigt eine Ansicht entsprechend der Linie II-II von Fig. 1.FIG. 2 shows a view along the line II-II of FIG. 1.
Gemäß Fig. 1 ist ein Revolver 1 vorgesehen, der sieben Zellen 2 aufweist und mittels eines Schrittschaltantriebs schrittweise um jeweils eine Zellenteilung um seine Achse 3 drehbar ist. Der Revolver 1 umfaßt eine Revolverscheibe 4 und einen dazu mit Abstand angeordneten Ring 5, wobei die Scheibe 4 und der Ring 5 durch Führungsstangen 6 miteinander verbunden sind. Jede Zelle 2 des Revolvers 1 besitzt einen Zellenfuß 7, der über ein Paar von Führungsstangen 6 zwischen der Scheibe 4 und dem Ring 5 axial verschieblich angeordnet ist, da die Führungsstangen 6 parallel zur Achse 3 des Revolvers 3 verlaufen.1, a revolver 1 is provided which has seven
Koaxial zur Achse 3 und parallel zur Scheibe 4 ist eine ortsfest angeordnete Führungsscheibe 8 angeordnet, während jeder Fuß 7 jeder Zelle 2 mit jeweils zwei Führungsrollen 9 an der der Achse 3 zugewandten Seite versehen ist, wobei die beiden Führungsrollen 9 jeder Zelle 2 mit den beiden Stirnseiten der Führungsscheibe 8 in Eingriff stehen, so daß die Zellen 2 durch die Führungsscheibe 8 während des Umlaufs des Revolvers 1 in ihrer Position gehalten werden.Coaxially to the
Die Führungsscheibe 8 besitzt entsprechend einer Übergabeposition zu einer Förderkette 1o einen Ausschnitt 11, der durch einen Einsatz 12 von der Stärke der Führungsscheibe 8 eingenommen wird. Der Einsatz 12 ist mit einer Schubstange 13 eines von einer Kurve 14 gesteuerten Kurbeltriebs 15 verbunden.Corresponding to a transfer position to a
Die Förderkette 1o besitzt in äquidistanten Abständen Mitnehmer 16 und ist kontinuierlich mit konstanter Geschwindigkeit über einen entsprechenden Antrieb angetrieben. Die Mitnehmer 16 bestehen aus einem Mitnehmerarm 17 und einer quer dazu angeordneten Mitnehmerplatte 18, deren Abmessungen etwas kleiner als diejenigen der dem Mitnehmer 16 zugewandten Stirnseite von durch den Mitnehmer 16 zu übernehmenden Gegenständen 19 sind. Die Zellen 2 besitzen jeweils einen Schlitz 2o, damit der Mitnehmerarm 17 die Mitnehmerplatte 18 durch die in Axialrichtung offene Zelle 2 hindurchführen kann.The conveyor chain 1o has
Wenn sich eine Zelle 2 in Übergabeposition zur Förderkette 1o befindet, liegen ihre Führungsrollen 9 an dem Einsatz 12 der Führungsscheibe 8 an und der Einsatz 12 wird über den Kurbeltrieb 15 in Axialrichtung zunächst beschleunigt, dann auf Null abgebremst, anschließend wieder in umgekehrter Richtung beschleunigt und schließlich wieder zum Erreichen der Ausgangsposition auf Null abgebremst. Hierdurch wird die in Übergabeposition befindliche Zelle 2 entlang der Führungsstangen 6 in Axialrichtung entsprechend beschleunigt. Die Beschleunigung durch den Kurbeltrieb 15 erfolgt derart, daß die Zelle 2 beim Erreichen des in der Zelle 2 befindlichen, zu übernehmenden Gegenstandes 19 durch den Mitnehmer 16 praktisch die Geschwindigkeit der Förderkette 1o besitzt. Dies erfolgt etwa dann, wenn die Zelle 2 die Hälfte bis Zweidrittel des in Axialrichtung zurückzulegenden Weges zurückgelegt hat, punktiert in Fig. 1 dargestellt. In diesem Moment gelangt die Mitnehmerplatte 18 in Eingriff mit dem zu übernehmenden Gegenstand 19 praktisch ohne Relativgeschwindigkeit hierzwischen, so daß das Auftreffen der Mitnehmerplatte 18 auf den Gegenstand 19 schonend für letzteren stattfindet. Da die Zelle 2 auf ihrem weiteren Weg in Förderrichtung des Kettenförderers 1o bis auf Null abgebremst wird, schiebt der Mitnehmer 16 den Gegenstand 19 anschließend aus der von diesem überholten Zelle 2 heraus. Letztere wird dann durch den Kurbeltrieb 15 in ihre Ausgangsposition zurückgefahren, so daß beim Weiterschalten des Revolvers 1 ihre Führungsrollen 9 in Eingriff mit der Führungsscheibe 8 gelangen.When a
Der Revolver 1 kann auch kontinuierlich umlaufend ausgebildet sein, wobei dann jedoch die Zellen 2 mit ihren Führungsstangen 6 an Schwenkhebeln zu befestigen sind, die derart kurvengesteuert sind, daß die Zellen 2 im Übergabebereich vor Erreichen der Übergabeposition in diese geschwenkt und während eines für die Übergabe genügend langen Zeitraums in dieser Position gehalten werden, so daß die Zellen 2 trotz der kontinuierlichen Drehung des Revolvers 1 während der Übergabeposition praktisch stillstehend gehalten werden, wie es in der Patentanmeldung P 39 43 086.3 beschrieben ist.The turret 1 can also be continuously rotating, but then the
