Description

Die Erfindung betrifft ein Verfahren zum Verpakken von blockförmigen Artikelgruppen aus stabförmigen Artikeln der tabakverarbeitenden Industrie, welche in regelmäßigen Abständen kontinuierlich zugefördert werden und während ihrer Zuförderung zwecks kontinuierlicher Weiterförderung durch Verschieben querzurZuförderrichtung sowie quer zu den Längsachsen der stabförmigen Artikel von einem Förderabschnitt auf einen anderen Förderabschnitt überführt und dabei wenigstens teilweise mit einem Verpackungszuschnitt umhüllt werden.The invention relates to a method for packaging block-shaped article groups from rod-shaped articles of the tobacco processing industry, which are continuously conveyed at regular intervals and are transferred from one conveyor section to another conveyor section during their conveyance for the purpose of continuous further conveyance by moving them transversely to the direction of conveyance and transversely to the longitudinal axes of the rod-shaped articles and are at least partially wrapped with a packaging blank.

Die Erfindung betrifft außerdem eine Vorrichtung zum Fördern von zu verpackenden stabförmigen Artikeln dertabakverarbeitenden Industrie auf Fördermitteln, welche mit einem kontinuierlich antreibbaren, als Faltrevolver ausgebildeten Fördermittel zusammenwirken und die mit Aufnahmetaschen versehen sind, welche nacheinander Artikelgruppen in der Formation und Größe des Inhalts einer Verpackung aufnehmen.The invention also relates to a device for conveying rod-shaped articles to be packaged in the tobacco processing industry on conveying means which interact with a continuously drivable conveying means designed as a folding turret and which are provided with receiving pockets which successively accommodate groups of articles in the formation and size of the contents of a packaging.

Mit der EP-A-30359 ist ein Verfahren bzw. eine Vorrichtung zum Verpacken von Zigaretten bekanntgeworden, wonach eine Blockübergabe quer zu den Längsachsen der Zigaretten zwischen zwei sich tangierenden, kontinuierlich laufenden Förderern erfolgt, indem die Zigarettenblöcke mit ihrer großen Fläche voran radial verschoben werden, so daß der in Radialrichtung verlaufende Überführungshub eine der Breite der schmalen Seitenflächen der Zigarettenblöcke entsprechende Strecke beträgt.EP-A-30359 discloses a method and a device for packaging cigarettes, according to which block transfer takes place transversely to the longitudinal axes of the cigarettes between two tangent, continuously running conveyors, in that the large surface area of the cigarette blocks is radially displaced so that the radial transfer stroke is a distance corresponding to the width of the narrow side surfaces of the cigarette blocks.

Der Erfindung liegt die Aufgabe zugrunde, die Leistungsfähigkeit derartiger Verfahren und Vorrichtungen zum Verpacken von Tabakartikeln, wie Zigaretten, zu erhöhen.The object of the invention is to increase the performance of such methods and devices for packaging tobacco articles, such as cigarettes.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Artikelgruppen in einer derart hochkant ausgerichteten Blockformation entlang eines gemeinsamen Förderweges der beiden Förderabschnitte transportiert werden, daß jeweils eine Breitseite der jeweiligen Förderrichtung zugewandt ist und jeweils eine Schmalseite der Querschieberichtung zugewandt ist. Gemäß einer die Effektivität des erfindungsgemäßen Verfahrens erhöhenden Ausgestaltung werden während der kontinuierlichen Weiterförderung der Artikeigruppen an ihnen Verpackungsoperationenvorgenommen. Eine Vervollkommnung derverfahrensweise besteht darin, daß die kontinuierliche Weiterförderung der Artikelgruppen eine zusätzliche Querverschiebung mit integrierter Zuschnittumhüllung und kontinuierlicher Abförderung umfaßt.This object is achieved in that the article groups are transported in such an upright aligned block formation along a common conveying path of the two conveying sections that a broad side faces the respective conveying direction and a narrow side faces the transverse sliding direction. According to a configuration which increases the effectiveness of the method according to the invention, packaging operations are carried out on them during the continuous further conveyance of the article groups. A perfection of the procedure is that the continuous further conveyance of the article groups includes an additional transverse shift with integrated blank wrapping and continuous removal.

Um das erfindungsgemäße Verfahren auf einem relativ eng begrenzten Raum realisieren zu könne, wird außerdem vorgeschlagen, daß Züförderung, Weiterförderung und Abförderung der Artikelgruppen einen im wesentlichen Z-förmigen Förderweg beschreiben.In order to be able to implement the method according to the invention in a relatively narrowly limited space, it is also proposed that feed conveyance, further conveyance and removal of the article groups describe an essentially Z-shaped conveying path.

Die Vorrichtung zur Durchführung des eingangs bezeichneten Verfahrens zeichnet sich dadurch aus, daß die Fördermittel als kontinuierlich antreibbare Endlosförderer ausgebildet sind, die mit der ebenfalls Aufnahmetaschen aufweisenden Umfangsfläche des Faltrevolvers einen gemeinsamen Förderabschnitt mit jeweils radial auf die Drehachse des Faltrevolvers ausgerichteten, paarweise miteinander fluchtenden Aufnahmetaschen des Faltrevolvers und der Fördermittel bilden, wobei die Aufnahmetaschen derart in die Fördermittel eingelassen sind, daß ihre Überführungsöffnung einer schmalen Seitenfläche einer blockförmigen Artikelformation entspricht.The device for carrying out the method described at the outset is characterized in that the conveying means are designed as continuously drivable endless conveyors which, with the circumferential surface of the folding turret, which also has receiving pockets, have a common conveying section, each with receiving pockets which are aligned radially with respect to the axis of rotation of the folding turret and are aligned in pairs Form folding turret and the conveying means, the receiving pockets being embedded in the conveying means in such a way that their transfer opening corresponds to a narrow side face of a block-shaped article formation.

Eine sich in den gemeinsamen Förderbewegungsablauf der Fördermittel harmonisch einfügende Überführungsbewegung der Artikelgruppen ist in einer Fortführung der Erfindung dadurch gewährleistet, daß den Fördermitteln radial bewegbare, Artikelgruppen auf dem gemeinsamen Förderabschnitt aus den Aufnahmetaschen eines Fördermittels in die Aufnahmetaschen des jeweils anderen Fördermittels überführende Stößelglieder zugeordnet sind.In a continuation of the invention, a transfer movement of the article groups which is harmoniously integrated into the common conveying movement sequence of the conveying means is ensured by the fact that the conveying means are assigned pusher members which move radially movable, groups of articles on the common conveying section from the receiving pockets of one conveying means into the receiving pockets of the respective other conveying means.

Eine exakte Positionierung bzw. Ausrichtung des Verpackungsmaterials relativ zu den zu umhüllenden Artikelgruppen ist vorschlagsgemäß am einfachsten dadurch gewährleistet, daß die Aufnahmetaschen jeweils eines der zusammenwirkenden Fördermittel begrenzenden Umfangsabschnitte als Halteflächen für die Überführungsöffnungen der Aufnahmetaschen überdeckende Packungszuschnitte ausgebildet sind, wobei nach einer Weiterbildung die Umfangsabschnitte des Faltrevolvers als Halteflächen ausgebildet sind.According to the proposal, an exact positioning or alignment of the packaging material relative to the article groups to be encased is easiest ensured by the fact that the receiving pockets are each designed to hold one of the cooperating conveying means delimiting peripheral sections as holding surfaces for the transfer openings of the receiving pockets covering package blanks, the peripheral sections of the Folding turret are designed as holding surfaces.

Gemäß bevorzugten Ausgestaltungen wird der gemeinsame Förderabschnitt durch ein über einen Teil der Umlaufbahn des Faltrevolvers parallel zu dessen Umfangsfläche verlaufendes Fördertrum der Fördermittel gebildet, wobei das Fördertrum der Fördermittel durch eine ortsfeste Rollenbahn geführt ist.According to preferred embodiments, the common conveying section is formed by a conveying strand of the conveying means running parallel to its circumferential surface over part of the orbit of the folding turret, the conveying strand of the conveying means being guided by a stationary roller conveyor.

Die Integration von Transport bzw. Überführung und Verpackungsvorgängen wird gemäß einer Weiterbildung dadurch arrangiert, daß die einen Fördermittel blockförmige Artikelgruppen an den Faitrevoiverabgebend und die anderen Fördermittel teilumhüllte Artikelgruppen vom Faltrevolver übernehmend ausgebildet sind, wobei nach einem weiteren Vorschlag die Anordnung so getroffen ist, daß die die Artikelgruppen abgebenden Fördermittel mit einem ersten Kreisbahnabschnitt und die die teilumhüllten Artikelgruppen übernehmenden Fördermittel mit einem zweiten Kreisbahnabschnitt des Falterevolvers zusammenwirkend angeordnet sind.According to a further development, the integration of transport or transfer and packaging processes is arranged in such a way that the one block of article groups delivering funds to the Faitrevoiver and the other article groups are partially wrapped by the folding turret, whereby according to a further proposal the arrangement is such that the the conveying means delivering article groups with a first circular path section and the conveying means taking over the partially wrapped article groups with a second circular path section of the folding revolver are arranged to cooperate.

Eine die Baulänge der Vorrichtung reduzierende Anordnung besteht darin, daß die Förderbahnen der Fördermittel und des Faltrevolvers im wesentlichen in Z-Form verlaufen. Um diese bereits in ihrem räumlichen Verlauf gedrungen konzipierte Förderstrecke zusätzlich für Verpackungsoperationen optimal zu nutzen, sind gemäß einer vorteilhaften Weiterbildung dem Faltrevolver entlang seiner Förderbahn Einschläger zum Bilden eines Innen-, Außen-, Schmalseiten- und Breitseiteneinschlags der äußeren Packungszuschnitte zugeordnet.An arrangement reducing the overall length of the device consists in the fact that the conveying tracks of the conveying means and the folding turret run essentially in a Z-shape. In order to optimally use this conveying route, which is already compact in terms of its spatial layout, for packaging operations, in accordance with an advantageous further development, the folding turret along its conveying path is assigned impactors for forming an inside, outside, narrow side and broad side wrapping of the outer packaging blanks.

Der mit der Erfindung erzielte Vorteil besteht in derart aufeinander abgestimmten Bewegungen von zusammenwirkenden Fördermitteln, daß ein kontinuierlicher Förderfluß konsequent durchgehalten werden kann und daß in diesen Förderfluß Verpackungsvorgänge so integriert sind, daß bei einem ausgewogeneren Geschwindigkeitsverlauf ohne abrupte Verzögerungen und Beschleunigungen der zu verpackenden Artikel insgesamt eine Leistungssteigerung der Verpackungsorgane sowie eine schonendere Handhabung bei zugleich fester Verpackung der Artikel erzielt werden.The advantage achieved by the invention consists in such coordinated movements of cooperating conveying means that a continuous flow of conveyance can be consistently maintained and that packaging processes are integrated into this conveying flow in such a way that, with a more balanced speed profile, without abrupt delays and accelerations of the articles to be packaged, one overall Performance increase of the packaging organs as well as a gentler handling with firm packing of the articles at the same time.

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.

Hierbei zeigen:

  • Figur 1 eine schematisch dargestellte Verpakkungsvorrichtung gemäß Erfindung in der Seitenansicht,
  • Figur 2 einen Schnitt durch die Verpackungsvorrichtung nach der Linie 11-11 gemäß Figur 1 und
  • Figure 3 einen Schnitt durch die Verpackungsvorrichtung nach der Linie 111-111 gemäß Figur 1.

  • FIG. 1 shows a schematically illustrated packaging device according to the invention in a side view,
  • Figure 2 shows a section through the packaging device along the line 11-11 of Figure 1 and
  • Figure 3 shows a section through the packaging device along the line 111-111 according to Figure 1.

Die in der Zeichnung dargestellte Vorrichtung zum Verpacken von Zigaretten 1 weist ein Fördermittel in Form eines kontinuierlich in Pfeilrichtung 2 angetriebenen Falterevolvers 3 auf, welcher unterseitig mit einem synchron und kontinuierlich angetriebenen Fördermittel in Form eines Endlosförderers 4 und oberseitig ebenfalls mit einem als synchron und kontinuierlich antreibbarer Endlosförderer 6 ausgebildeten Fördermittel zusammenwirkt. Die beiden Endlosförderer 4 und 6 sind mit ihren in Pfeilrichtung 7 bzw. 8 zum Faltrevolver hin- bzw. von diesem wegführenden Fördertrumen 9 bzw. 11 derart relativ zum Faltrevolver 3 angeordnet, daß sich ein im wesentlichen Z-förmig verlaufender Förderweg für die zu verpakkenden Zigaretten ergibt.The device for packaging cigarettes 1 shown in the drawing has a conveying means in the form of a folding turret 3 which is driven continuously in the direction of the arrow 2, which on the underside has a synchronously and continuously driven conveying means in the form of an endless conveyor 4 and on the top side also a synchronously and continuously drivable one Endless conveyor cooperates 6 trained funding. The two endless conveyors 4 and 6 are arranged relative to the folding turret 3 with their conveying strands 9 and 11 leading to or away from the folding turret in the direction of the arrows 7 and 8, respectively, such that an essentially Z-shaped conveying path for those to be packaged Results in cigarettes.

Die beiden Endlosförderer 4 und 6 weisen jeweils über einen Teil des Förderweges entlang eines ersten, unteren Kreisbahnabschnittes bzw. entlang eines zweiten, oberen Kreisbahnabschnittes des Faltrevolvers 3 mit diesem einen gemeinsamen Förderabschnitt 12 bzw. 13 auf, was gemäß den Figuren 2 und 3 dadurch erreicht wird, daß die Fördertrume 9 bzw. 11 der Endlosförderer 4 und 6 in ortsfesten Rollenbahnen 14 so geführt sind, daß sie der Umlaufbahn des Faltrevolvers 3 über eine Teilstrecke folgen bzw. dieser parallel verlaufend angepaßt sind.The two endless conveyors 4 and 6 each have a common conveying section 12 and 13 over part of the conveying path along a first, lower circular path section or along a second, upper circular path section of the folding turret 3, which is achieved according to FIGS. 2 and 3 is that the conveyor strands 9 and 11 of the endless conveyors 4 and 6 are guided in fixed roller conveyors 14 so that they follow the orbit of the folding turret 3 over a section or are adapted to run in parallel.

Der Faltrevolver 3 sowie die Endlosförderer 4 und 6 sind mit in gleichmäßigen Abständen und gleicher Teilung angeordneten Aufnahmetaschen 26 bzw. 17 versehen, die zur Aufnahme der zu verpackenden Zigaretten in Form von blockförmig zusammengestellten Zigarettengruppen 18 dienen, indem die Zigaretten 1 über einzelne entlang der Förderbahn des Endlosförderers 4 hintereinanderliegende Zuführschächte 19 eines Magazins 21 lagenweise und queraxial über die an ihrer oberen Schmalseite befindliche Aufnahmeöffnung in die Aufnahmetaschen 17 überführt werden. Dabei wird ein freier Fall der Zigaretten 1 bis auf den Boden der Aufnahmetasche durch ein Stößelglied 22 verhindert, welches entsprechend der aufeinanderfolgend eingegebenen Zigarettenlagen gesteuert bis in die untere dargestellte Position abgesenkt wird. Den Aufnahmetaschen 17 des oberen Endlosförderers 6 sind ebenfalls entsprechende Stößelglieder 23 und den Aufnahmetaschen 16 des Faltrevolvers 3 Stößelglieder 24 zugeordnet.The folding turret 3 and the endless conveyors 4 and 6 are provided with receiving pockets 26 and 17, which are arranged at equal intervals and in the same division and are used to hold the cigarettes to be packaged in the form of cigarette groups 18 arranged in blocks, by moving the cigarettes 1 one by one along the conveyor track of the endless conveyor 4, feed chutes 19 of a magazine 21 lying one behind the other are transferred in layers and transversely axially into the receiving pockets 17 via the receiving opening located on their upper narrow side. A free fall of the cigarettes 1 down to the bottom of the receiving pocket is prevented by a pusher member 22, which is lowered according to the successively entered cigarette layers down to the position shown below. Corresponding tappet members 23 are also assigned to the receiving pockets 17 of the upper endless conveyor 6 and 3 tappet members 24 to the receiving pockets 16 of the folding turret.

Der äußere Umfang des Faltrevolvers 3 dient gleichzeitig als Haltefläche 26 für Packungszuschnitte 27 eines inneren Blockeinschlags und für Packungszuschnitte 28 einer äußeren Blockumhüllung, wobei die Haltefläche mit Saugluft beaufschlagt sein kann. Die Packungszuschnitte 27 werden durch eine Messerwalzenanordnung 29 von einer in Pfeilrichtung 31 zugeführten Hüllmaterialbahn 32 abgeschnitten und mittels einer Saugwalze 33 auf die Haltefläche 26 des Faltrevolvers 3 derart aufgelegt, daß sie dessen Aufnahmetaschen 16 überdecken.The outer circumference of the folding turret 3 serves at the same time as a holding surface 26 for pack blanks 27 of an inner block wrapper and for pack blanks 28 of an outer block wrapper, wherein the holding surface can be acted upon by suction air. The pack blanks 27 are cut off by a knife roller arrangement 29 from a wrapping material web 32 fed in the direction of the arrow 31 and placed on the holding surface 26 of the folding turret 3 by means of a suction roller 33 such that they cover the receiving pockets 16 thereof.

Die Aufnahmetaschen 16 des Faltrevolvers 3 mit den sie überdeckenden Packungszuschnitten 27 und die Aufnahmetaschen 17 mit den darin befindlichen, mit ihrer Breitseite der Förderrichtung zugewandten Zigarettengruppen 18 werden kontinuierlich dem gemeinsamen Förderabschnitt 12 zugeführt, auf dem die Aufnahmetaschen 17 des Endlosförderers 4 und die Aufnahmetaschen 16 des Faltrevolvers 3 paarweise miteinander fluchten und radial auf die Drehachse des Faltrevolvers 3 ausgerichtet sind. Beim Beginn dieser fluchtenden Ausrichtung in dem in Figur 2 dargestellten Bereich wird die Zigarettengruppe 18 quer zur Zuförderrichtung mit einer Schmalseite voran durch das Stößelglied 22 gemeinsam mit dem zwischen der Aufnahmetasche 17 des Endlosförderers 4 und der Aufnahmetasiche 16 des Faltrevolvers 3 befindlichen Pakkungszuschnitt 27 in die Aufnahmetasche 16 des Falterevolvers 3 geschoben, wobei das Stößelglied 24 des Faltrevolvers 3 in gleichem Maße gesteuert zurückweicht wie das Stößelglied 22 vorgeschoben wird, so daß sich der Packungszuschnitt 27 um die Zigarettengruppe 18 herumlegt. Dieser Bewegungsablauf ist in dem in Figur 3 dargestellten Bereich beendet. Die wie bereits zuvor auf dem Endlosförderer 4 mit ihrer Breitseite der Förderrichtung zugewandten und nunmehr teilumhüllten Zigarettengruppen 18 werden anschließend ebenfalls mit ihrer Breitseite voran einer Faltstation 34 des Faltrevolvers 3 zugeführt, an der zwei Einschläger 36 und 37 einen Inneneinschlag 38 sowie einen Außeneinschlag 39 an der Zigarettengruppe 18 ausführen. An einer stromab folgenden Faltstation 41 wird durch einen Einschläger 42 der Schmalseiteneinschlag 43 und an einer sich daran anschließenden Faltstation 44 mittels eines Einschlägers 46 der Breitseiteneinschlag 47 ausgeführt.The receiving pockets 16 of the folding turret 3 with the packaging blanks 27 covering them and the receiving pockets 17 with the cigarette groups 18 located therein with their broad side facing the conveying direction are continuously fed to the common conveyor section 12 on which the receiving pockets 17 of the endless conveyor 4 and the receiving pockets 16 des Folding turret 3 aligned in pairs and radially aligned with the axis of rotation of the folding turret 3. At the beginning of this alignment in the area shown in Figure 2, the cigarette group 18 is transversely to the feed direction with a narrow side ahead through the pusher member 22 together with the package blank 27 located between the receiving pocket 17 of the endless conveyor 4 and the receiving pocket 16 of the folding turret 3 into the receiving pocket 16 of the folding turret 3 is pushed, the tappet member 24 of the folding turret 3 retreating in a controlled manner to the same extent as the tappet member 22 is pushed forward, so that the package blank 27 wraps around the cigarette group 18. This sequence of movements has ended in the area shown in FIG. The broad side of the cigarette groups 18, as already previously on the endless conveyor 4 with its broad side facing the conveying direction and now partially encased, are then fed to a folding station 34 of the folding turret 3, on which two wefts 36 and 37 have an inner wrap 38 and an outer wrap 39 on the Run cigarette group 18.
