Description

Die Erfindung betrifft ein Verfahren zum Einhüllen von Packungen, insbesondere quaderförmigen Zigaretten-Packungen, in Zuschnitte, die beim Einschieben der Packungen in Taschen eines Faltrevolvers U-förmig um die Packungen herumgelegt und deren überstehende Lappen sodann gefaltet werden, wobei dem Faltrevolver mehrere, insbesondere zwei Packungen parallel nebeneinander zugeführt werden und wobei die Zuschnitte von einer gemeinsamen Materialbahn abgetrennt und positionsgerecht in die Bewegungsbahn der Packungen gefördert werden. Weiterhin betrifft die Erfindung eine Vorrichtung gemäß dem Oberbegriff des Anspruchs 6 (solch ein Verfahren und solch eine Vorrichtung sind aus der EP-A-0 135 818 bekannt).The invention relates to a method for wrapping packs, in particular cuboid cigarette packs, in blanks which are placed around the packs in a U-shape when the packs are inserted into pockets of a folding turret and the projecting tabs are then folded, the folding turret being provided with several, in particular two Packs are fed in parallel next to each other and the blanks are separated from a common material web and conveyed into the movement path of the packs in the correct position. Furthermore, the invention relates to a device according to the preamble of claim 6 (such a method and such a device are known from EP-A-0 135 818).

Zigaretten-Packungen sind überwiegend mit einer Außenumhüllung aus einer dünnen Folie versehen. Die Erfindung befaßt sich in erster Linie mit dem Herstellen der Außenumhüllung für Zigaretten-Packungen.Cigarette packs are mostly provided with an outer wrapping made of a thin film. The invention is primarily concerned with the manufacture of the outer wrapper for cigarette packs.

Verpackungsmaschinen für die Außenumhüllung von Zigaretten-Packungen müssen sehr leistungsfähig sein, entsprechend der hohen Leistung der vorgeordneten Verpackungsmaschinen für die Herstellung der Zigaretten-Packungen. Aus der EP-A-0 135 818 ist eine Verpackungsmaschine zur Herstellung von Zigaretten-Packungen bekannt, bei der einem Faltrevolver aufeinanderfolgende Zigaretten-Packungen in radialer Richtung zugeführt werden. Zugleich werden in axialer Richtung je zwei Packungen nebeneinander zugeführt. Während des Einschubs der Packungen in entsprechend angeordnete Taschen des Faltrevolvers werden die zwei nebeneinanderliegenden Packungen in einen gemeinsamen Gesamt-Zuschnitt entsprechender Breite eingehüllt. Der vorgesehene Faltrevolver weist besonders große Abmessungen in axialer Richtung auf. Am Umfang des Faltrevolvers angeordnete Faltorgane müssen entsprechend breit ausgebildet sein.Packaging machines for the outer wrapping of cigarette packs must be very efficient, in accordance with the high performance of the upstream packaging machines for the manufacture of the cigarette packs. From EP-A-0 135 818 a packaging machine for producing cigarette packs is known, in which successive cigarette packs are fed in the radial direction to a folding turret. At the same time, two packs are fed side by side in the axial direction. During the insertion of the packs into suitably arranged pockets of the folding turret, the two packs lying next to one another are encased in a common overall blank of corresponding width. The folding turret provided has particularly large dimensions in the axial direction. Folding elements arranged on the circumference of the folding turret must have a correspondingly wide design.

Aufgabe des erfindungsgemäßen Verfahrens sowie der Vorrichtung ist es, bei einer "normalen" axialen Baulänge des Faltrevolvers einen zuverlässigen und einfachen Ablauf der Übergabe der Packungen an den Faltrevolver zu gewährleisten.The object of the method and the device according to the invention is to ensure a reliable and simple process of transferring the packs to the folding turret with a "normal" axial length of the folding turret.

Zur Lösung dieser Aufgabe ist das erfindungsgemäße Verfahren dadurch gekennzeichnet, daß die Packungen - relativ zum Faltrevolver - in einer gemeinsamen, queraxialen Ebene und in Umfangsrichtung parallel nebeneinander bereitgehalten und in dieser Ebene in die entsprechenden Taschen des Faltrevolvers eingeschoben werden.To achieve this object, the method according to the invention is characterized in that the packs - relative to the folding turret - are kept ready next to one another in a common, transverse axial plane and in the circumferential direction and are pushed into the corresponding pockets of the folding turret in this plane.

In ähnlicher Weise ist die erfindungsgemäße Vorrichtung dadurch gekennzeichnet, daß die Taschen zur Aufnahme der nebeneinander zuzuführenden Packungen im Faltrevolver in einer queraxialen Ebene und in Umfangsrichtung parallel nebeneinander angeordnet sind.In a similar manner, the device according to the invention is characterized in that the pockets for receiving the packs to be supplied next to one another are arranged in the folding turret in a transverse axial plane and parallel to one another in the circumferential direction.

Die Materialbahn wird abschnittweise, nämlich jeweils in der Abmessung von zwei Zuschnitten entsprechenden Bahnabschnitten, der Umhüllungsstation zugeführt. Die Zuschnitte werden dabei in der Bewegungsbahn der Zigaretten-Packungen bereitgehalten, quer zu diesen gerichtet. Durch gewölbte, wellenförmige Anordnung der Zuschnitte bzw. des Bahnabschnitts ist es möglich, die beiden gleichzeitig eingehüllten Verpackungen mit verhältnismäßig geringem Abstand nebeneinander zu verschieben, ohne daß die Zuschnitte einander überdecken müssen.The material web is fed to the wrapping station in sections, namely in each case in the dimension of two sections corresponding to web sections. The blanks are in the path of movement of the cigarette packs held ready, directed transversely to them. By means of a curved, wave-shaped arrangement of the blanks or of the web section, it is possible to move the two simultaneously wrapped packs next to one another at a relatively short distance without the blanks having to overlap one another.

Die Förderorgane für die Zuführung der Materialbahn sind als Förderwalze ausgebildet, wobei mindestens eine dieser Förderwalzen eine Messerwalze ist, die den Bahnabschnitt und die Zuschnitte durch präzisen Trennschnitt herstellt. Jeweils eine Förderwalze ist einer Zigaretten-Packung bzw. einer Bewegungsbahn derselben zugeordnet. Diese Förderwalzen sind mit einem mittigen, schlitzförmigen Durchgang versehen, durch den die Packungen hindurchgeschoben werden unter Mitnahme der auf dem Mantel der Förderwalzen gehaltenen Zuschnitte.The conveyor elements for feeding the material web are designed as a conveyor roller, at least one of these conveyor rollers being a knife roller which produces the web section and the blanks by means of a precise separating cut. A conveyor roller is assigned to a cigarette pack or a movement path of the same. These conveyor rollers are provided with a central, slot-shaped passage through which the packs are pushed, taking the blanks held on the jacket of the conveyor rollers.

Die zu verpackenden Gegenstände - insbesondere Zigaretten-Packungen - werden nach einem weiteren Vorschlag der Erfindung aus einer Dichtreihe von Zigaretten-Packungen durch Hubbewegung unter Mitnahme der Zuschnitte in die Taschen des Faltrevolvers eingeführt.According to a further proposal of the invention, the objects to be packaged - in particular cigarette packs - are inserted from a sealed row of cigarette packs by a lifting movement, taking the blanks with them, into the pockets of the folding turret.

Weitere Merkmale der Erfindung beziehen sich auf die Ausgestaltung von Förder- und Halteorganen für die Materialbahn und die Zuschnitte, auf Einschuborgane für die Zigaretten-Packungen in den Faltrevolver sowie auf die Ausbildung des Faltrevolvers.Further features of the invention relate to the design of conveying and holding members for the material web and the cuts, to insertion members for the cigarette packs in the folding turret and to the design of the folding turret.

Die in den Zeichnungen als Ausführungsbeispiel dargestellte Vorrichtung ist besonders vorteilhaft für die Herstellung bzw. für das Einhüllen quaderförmiger Zigaretten-Packungen 10 geeignet. Im einzelnen geht es um die Bildung einer Außenumhüllung 11 als Zellglas, Poly-Folie oder dergleichen.The device shown as an exemplary embodiment in the drawings is particularly advantageously suitable for the production or for wrapping cuboid packs 10 in the form of cuboids. In detail, it is about the formation of an outer envelope 11 as cellophane, poly film or the like.

Die Außenumhüllung 11 besteht aus einem rechteckigen Zuschnitt 12 bzw. 13. Dieser wird in einem ersten Faltschritt U-förmig um die Zigaretten-Packung 10 herumgelegt unter Bildung einer in Bewegungsrichtung vornliegenden Seitenwand 14. Auf der zu dieser gegenüberliegenden weiteren Seitenwand 15 wird eine in Längsrichtung derselben verlaufende Überlappung von entsprechend bemessenen Seitenwandlappen 16 und 17 gebildet. Diese sind im Bereich ihrer Überlappung miteinander verbunden, insbesondere durch Siegeln.The outer wrapper 11 consists of a rectangular blank 12 or 13. In a first folding step, this is placed around the cigarette pack 10 in a U-shape, forming a front one in the direction of movement Side wall 14. An overlap of correspondingly dimensioned side wall tabs 16 and 17 is formed in the longitudinal direction thereof on the further side wall 15 opposite this. These are connected to one another in the area of their overlap, in particular by sealing.

Eine Bodenwand 18 und eine in gleicher Weise ausgebildete obere Stirnwand 19 der Außenumhüllung 11 sind als Couvert-Faltung ausgebildet. Dabei werden als erstes Seitenendlappen 20 und 21 in Verlängerung der Seitenwandlappen 16, 17 gegen Bodenwand und Stirnwand der Zigaretten-Packung 10 gefaltet. Abschließend werden trapezförmige Längslappen 22, 23 zur Vollendung von Bodenwand 18 und Stirnwand 19 mit Überlappung gegeneinander gefaltet.A bottom wall 18 and an upper end wall 19 of the outer casing 11, which is designed in the same way, are designed as an envelope fold. The first side end flaps 20 and 21 are folded in an extension of the side wall flaps 16, 17 against the bottom wall and end wall of the cigarette pack 10. Finally, trapezoidal longitudinal tabs 22, 23 are folded against one another with an overlap to complete bottom wall 18 and end wall 19.

Die in dieser Weise einzuhüllenden Zigaretten-Packungen 10 kommen von einer Verpackungsmaschine (nicht dargestellt). In Dichtlage nebeneinanderliegend werden die Zigaretten-Packungen 10 auf einer Packungsbahn 24 zugefördert. Diese besteht aus einer Unterwand 25, einer Oberwand 26 und Seitenführungen 27. Innerhalb der so ausgebildeten Packungsbahn 24 werden die Zigaretten-Packungen 10 durch Übertragung des Vorschubs von einer Zigaretten-Packung 10 auf die andere taktweise gefördert.The cigarette packs 10 to be wrapped in this way come from a packaging machine (not shown). The cigarette packs 10 are conveyed in a sealing position next to one another on a packing track 24. This consists of a lower wall 25, an upper wall 26 and side guides 27. Within the packing track 24 thus formed, the cigarette packs 10 are conveyed in cycles by transferring the feed from one cigarette pack 10 to the other.

Im Bereich einer Einschubstation 28 werden die Zigaretten-Packungen 10 durch Abheben von der Packungsbahn 24 und Aufwärtsbewegung einem in vertikaler Ebene schrittweise drehenden Faltrevolver 29 übergeführt.In the area of an insertion station 28, the cigarette packs 10 are transferred to a folding turret 29, which rotates step by step in the vertical plane, by lifting them off the packing track 24 and moving upwards.

Der Faltrevolver 29 ist mit jeweils paarweise angeordneten Taschen 30, 31 versehen. In die auf der radial außenliegenden Seite offenliegenden Taschen 30, 31 wird jeweils eine Zigaretten Packung 10 von unten her eingeschoben, und zwar unter Mitnahme eines entsprechend bereitgehaltenen Zuschnitts 12, 13. Dieser legt sich dabei U-förmig um die Zigaretten-Packung 10 herum, ausgehend von der in Bewegungsrichtung vornliegenden Seitenwand 14.The folding turret 29 is provided with pockets 30, 31 arranged in pairs. In each case a cigarette packet 10 is inserted from below into the pockets 30, 31, which are open on the radially outer side, with the taking of a correspondingly provided blank 12, 13, which wraps itself around the U-shape Cigarette pack 10 around, starting from the side wall 14 lying forward in the direction of movement.

In den zu zweit parallel zueinander angeordneten Taschen 30, 31 werden die Zigaretten-Packungen 10 längs eines Dreiviertelkreises taktweise gefördert, unter Durchführung der beschriebenen Faltoperationen. Im Bereich einer Ausschubstation 32 werden die mit der fertigen Außenumhüllung 11 versehenen Zigaretten-Packungen 10 wiederum paarweise aus den Taschen 30, 31 aus- und in eine Abförderbahn 33 eingeschoben.In the two pockets 30, 31 arranged parallel to one another, the cigarette packs 10 are conveyed in cycles along a three-quarter circle, by carrying out the folding operations described. In the area of an ejection station 32, the cigarette packs 10 provided with the finished outer wrapper 11 are again pushed out in pairs from the pockets 30, 31 and inserted into a discharge conveyor 33.

Für die Übergabe der jeweils zwei Zigaretten-Packungen 10 an den Faltrevolver 29 ist im Bereich der Einschubstation 28 ein Doppelschieber 34 mit zwei im Abstand voneinander angeordneten, gemeinsam bewegten Stößeln 35, 36 angeordnet. Ein für die Stößel 35, 36 gemeinsamer Tragkörper 37 wird in geeigneter Weise auf- und abgehend angetrieben, im vorliegenden Falle über einen Schwinghebel 38 mit Lenker 39.For the transfer of the two cigarette packs 10 to the folding turret 29, a double slide 34 is arranged in the region of the insertion station 28, with two plungers 35, 36 arranged at a distance from one another and moving together. A support body 37 common for the tappets 35, 36 is driven up and down in a suitable manner, in the present case via a rocker arm 38 with a link 39.

Die Stößel 35, 36 treten durch schlitzförmige Ausnehmungen 40, 41 in der Unterwand 25 der Packungsbahn 24 hindurch. Die Stößel 35, 36 sind in einem derartigen Abstand voneinander angeordnet, daß zwischen den beiden aus einer Dichtreihe 42 der Zigaretten-Packungen 10 herausgehobenen Zigaretten-Packungen 10 ein Abstand entsprechend den Abmessungen von zwei Zigaretten-Packungen 10 entsteht. Dadurch wird zwischen den einzuhüllenden Zigaretten-Packungen 10 ein ausreichender Abstand hergestellt für die Mitnahme der beiden Zuschnitte 12 und 13 sowie für die Ausführung von Faltschritten im Bereich des Faltrevolvers 29.The plungers 35, 36 pass through slot-shaped recesses 40, 41 in the lower wall 25 of the packing web 24. The plungers 35, 36 are arranged at such a distance from one another that a distance corresponding to the dimensions of two cigarette packs 10 is formed between the two cigarette packs 10 lifted out of a sealing row 42 of the cigarette packs 10. As a result, a sufficient distance is produced between the cigarette packs 10 to be wrapped in order for the two blanks 12 and 13 to be carried along and for the folding steps to be carried out in the region of the folding turret 29.

Die Zigaretten-Packungen 10 werden mit den Zuschnitten 12, 13 durch die Stößel 35, 36 bis zu ihrer Endposition innerhalb der Taschen 30, 31 gefördert. Nach Rückkehr in die Ausgangsstellung (bündig mit Unterwand 25) wird die Dichtreihe 42 der Zigaretten-Packungen 10 um einen der Abmessung von zwei Zigaretten-Packungen 10 entsprechenden Weg weitergefördert, so daß eine durchgehende Dichtreihe 42 geschaffen ist unter Anlage an einer Endwandung 43 der Packungsbahn 24. Während des Ausschubs der beiden einzuhüllenden Zigaretten-Packungen 10 wird der nachfolgende Teil der Dichtreihe 42 an einer Weiterbewegung gehindert, und zwar durch Festklemmen von vornliegenden Zigaretten-Packungen 10 an der Oberwand 26 der Packungsbahn 24. Zu diesem Zweck ist ein Teilbereich der Unterwand 25 als Hubplatte 44 ausgebildet. Durch geringfügige Aufwärtsbewegung erfolgt das Festklemmen der beiden vorderen Zigaretten-Packungen 10 und damit ein Fixieren der Dichtreihe 42.The cigarette packs 10 are conveyed with the blanks 12, 13 through the plungers 35, 36 to their end position within the pockets 30, 31. After returning to the starting position (flush with bottom wall 25), the sealing row 42 of the cigarette packs 10 conveyed further by a path corresponding to the dimension of two cigarette packs 10, so that a continuous row of seals 42 is created, bearing against an end wall 43 of the pack web 24. During the ejection of the two cigarette packs 10 to be wrapped, the the subsequent part of the sealing row 42 is prevented from moving further, namely by clamping forward-lying cigarette packs 10 to the upper wall 26 of the packing web 24. For this purpose, a partial region of the lower wall 25 is designed as a lifting plate 44. The two front cigarette packs 10 are clamped by a slight upward movement and thus the sealing row 42 is fixed.

Die Zuschnitte 12 und 13 werden jeweils positionsgenau oberhalb der beiden aufwärtsbewegten Zigaretten-Packungen 10 in einer Ebene quer zu deren Bewegungsbahn bereitgehalten. Die Zigaretten-Packungen 10 treten über eine Ausschuböffnung 45, 46 der Oberwand 26 aus. Die Zuschnitte 12, 13 sind oberhalb dieser Ausschuböffnung 45, 46 bereitgehalten.The blanks 12 and 13 are each held in a position exactly above the two upwardly moving cigarette packs 10 in a plane transverse to their path of movement. The cigarette packs 10 exit through an ejection opening 45, 46 of the top wall 26. The blanks 12, 13 are kept ready above this ejection opening 45, 46.

Die beiden je einer Zigaretten-Packung 10 zugeordneten Zuschnitte 12, 13 werden von einer gemeinsamen, fortlaufenden Materialbahn 47 aus Verpackungsmaterial (Folie) abgetrennt. Die von einer nicht gezeigten Bobine abschnittsweise abgezogene Materialbahn 47 wird im wesentlichen horizontal, jedenfalls quer zur aufwärtsgerichteten Bewegungsbahn der Zigaretten-Packungen 10 der Einschubstation 28 zugeführt. Zwei angetriebene und entsprechend gesteuerte Zugwalzen 48, 49 besorgen den präzisen Vorschub. Die Materialbahn 47 läuft sodann über mehrere, drehend antreibbare Förderwalzen. Von diesen ist eine an die Zugwalzen 48, 49 anschließende als Messerwalze 50 ausgebildet mit einem umlaufenden Trennmesser 51 und einem feststehenden Gegenmesser 52. Die Messerwalze 50 ist so bemessen, daß in Verbindung mit einer entsprechenden Relativstellung von Trennmesser 51 und Gegenmesser 52 an passender Stelle ein Trennschnitt 53 zur Abtrennung der beiden Zuschnitte 12 und 13 voneinander und danach ein weiterer Trennschnitt 54 zur Abtrennung des (zweiten) Zuschnitts 13 von der Materialbahn 47 ausgeführt werden. Die Messerwalze 50 ist neben dem Trennmesser 51 mit Saugbohrungen 55 versehen, die mittels Saugluft das vordere, freie Ende der nachfolgenden Materialbahn 47 auf der Messerwalze 50 fixieren.The two blanks 12, 13, each associated with a cigarette pack 10, are separated from a common, continuous material web 47 made of packaging material (film). The material web 47 drawn off in sections from a bobbin, not shown, is fed to the insertion station 28 essentially horizontally, at least transversely to the upward movement path of the cigarette packs 10. Two driven and correspondingly controlled pull rollers 48, 49 ensure the precise feed. The material web 47 then runs over a plurality of conveyor rollers which can be driven in rotation. Of these, one adjoining the pulling rollers 48, 49 is designed as a knife roller 50 with a revolving separating knife 51 and a fixed counter knife 52. The knife roller 50 is dimensioned such that in connection with a corresponding relative position a separating cut 53 for separating the two blanks 12 and 13 from one another and then a further separating cut 54 for separating the (second) cut 13 from the material web 47 are made at a suitable point by the separating knife 51 and counter knife 52. In addition to the separating knife 51, the knife drum 50 is provided with suction bores 55 which fix the front, free end of the subsequent material web 47 on the knife drum 50 by means of suction air.

Die Materialbahn 47 wird während jedes Arbeitstaktes um einen der Abmessung der beiden Zuschnitte 12 und 13 entsprechenden Bahnabschnitt gefördert. Während des Transports erfolgt die Durchtrennung der Zuschnitte 12, 13 und die Abtrennung von der Materialbahn 47. Im Anschluß an die Messerwalze 50 wird die Materialbahn 47 bzw. werden die Zuschnitte 12, 13 unmittelbar an den Umfang weiterer walzenförmiger Förderorgane übergeben, die die Materialbahn 47 unter starken Umschlingungen in die Faltposition (Fig. 4) fördern.The material web 47 is conveyed during each work cycle by a web section corresponding to the dimensions of the two blanks 12 and 13. The cuts 12, 13 and the separation from the material web 47 take place during the transport. Following the knife roller 50, the material web 47 or the cuts 12, 13 are transferred directly to the circumference of further roller-shaped conveying members which transfer the material web 47 convey under strong wraps into the folded position (Fig. 4).

Walzenförderer 56 und 57 im Bereich der Einschubstation 28 dienen zugleich als Halteorgane für die Zuschnitte 12, 13 in exakter Relativstellung zur aufwärtsgerichteten Bewegungsbahn der Zigaretten-Packungen 10. Von diesen Walzenförderern 56, 57 werden die Zuschnitte 12, 13 bei der Aufwärtsbewegung der Zigaretten-Packungen 10 schlupfend abgezogen.Roller conveyors 56 and 57 in the area of the insertion station 28 also serve as holding members for the blanks 12, 13 in exact relative position to the upward movement path of the cigarette packs 10. The blanks 12, 13 become from these roller conveyors 56, 57 during the upward movement of the cigarette packs 10 slipping pulled off.

Bei dem gezeigten Ausführungsbeispiel bestehen die Walzenförderer 56, 57 aus seitlichen, drehend antreibbaren Saugscheiben 58, 59. Diese sind jeweils an der Außenseite mit antreibbaren Wellenzapfen 60 versehen. Die Saugscheiben 58, 59 sind in ihrer axialen Richtung so bemessen und derart im Abstand voneinander angeordnet, daß lediglich Randstreifen der Materialbahn 47 bzw. der Zuschnitte 12, 13 auf dem Umfang der Saugscheiben 58, 59 aufliegt und durch diese mittels Saugluft gehalten werden. Dieser Randstreifen entspricht dabei der Breite von über die Zigaretten-Packung 10 während dieser Phase hinwegstehenden Teilen der Zuschnitte 12, 13 zur späteren Bildung der Bodenwand 18 und Stirnwand 19.In the embodiment shown, the roller conveyors 56, 57 consist of lateral, rotatably drivable suction disks 58, 59. These are each provided on the outside with drivable shaft journals 60. The suction disks 58, 59 are dimensioned in their axial direction and spaced apart such that only edge strips of the material web 47 or the blanks 12, 13 lie on the circumference of the suction disks 58, 59 and are held by suction air. This edge strip corresponds to the width of parts of the blanks 12, 13 projecting beyond the cigarette pack 10 during this phase for the later formation of the bottom wall 18 and end wall 19.

Zwischen den seitlichen Saugscheiben 58, 59 sind aufrechte Stützwände 61, 62 bzw. 63, 64 gebildet. Diese sind paarweise den Saugscheiben 58, 59 als feststehende, unbewegliche Ergänzung der Walzenförderer 56, 57 zugeordnet. Die Stützwände 61..64 sind so ausgebildet, daß innen eine spaltförmige Durchtrittsöffnung 65, 66 in Fortsetzung der Ausschuböffnungen 45, 46 für den Durchschub der Zigaretten-Packungen 10 gebildet ist. Die Stützwände 61..64 sind bei dem gezeigten Ausführungsbeispiel mit der Oberwand 26 der Packungsbahn 24 verbunden bzw. bilden einen Teil derselben.Upright support walls 61, 62 and 63, 64 are formed between the lateral suction disks 58, 59. These are assigned in pairs to the suction disks 58, 59 as a fixed, immovable addition to the roller conveyors 56, 57. The support walls 61..64 are designed such that a gap-shaped passage opening 65, 66 is formed in the continuation of the ejection openings 45, 46 for the passage of the cigarette packs 10. In the exemplary embodiment shown, the support walls 61..64 are connected to the upper wall 26 of the packing web 24 or form part of the same.

An der Außenseite sind die Stützwände 61..64 so geformt, daß die Zuschnitte 12, 13 im Bereich derselben an abgerundeten bzw. gewölbten Außenflächen anliegen. Konkret sind die Stützwände 61..64 der zylindrischen Gestalt als Teil der Walzenförderer 56, 57 angepaßt. Im Bereich zwischen den Walzenförderern 56, 57 gehen die benachbarten Stützwände 62, 63 fließend in eine kreisbogenförmige Führungsmulde 67 der entsprechend geformten Oberseite der Oberwand 26 über. Die Materialbahn 47 bzw. die Zuschnitte 12, 13 werden unter Anlage an entsprechende Führungsflächen durch diese Führungsmulde 67 hindurchgefördert. In der Endposition sind die Zuschnitte 12, 13 auf den Walzenförderern 56, 57 bzw. den Saugscheiben 58, 59 derselben so fixiert, daß in bezug auf die zugeordneten Zigaretten-Packungen 10 eine geringfügige Außermittigkeit gegeben ist. Wie insbesondere aus Fig. 4 ersichtlich, werden dadurch die Zigaretten-Packungen 10 mit ungleich langen, nach unten weisenden Seitenwandlappen 16, 17 in die Taschen 30, 31 eingefördert.On the outside, the support walls 61..64 are shaped in such a way that the blanks 12, 13 rest in the region of the same on rounded or arched outer surfaces. Specifically, the support walls 61..64 are adapted to the cylindrical shape as part of the roller conveyors 56, 57. In the area between the roller conveyors 56, 57, the adjacent support walls 62, 63 flow smoothly into an arcuate guide trough 67 of the correspondingly shaped upper side of the upper wall 26. The material web 47 or the blanks 12, 13 are conveyed through this guide trough 67, bearing against corresponding guide surfaces. In the end position, the blanks 12, 13 are fixed on the roller conveyors 56, 57 or the suction disks 58, 59 thereof in such a way that there is a slight eccentricity in relation to the associated cigarette packs 10. As can be seen in particular from FIG. 4, the cigarette packs 10 are thereby fed into the pockets 30, 31 with unevenly long, downward-facing side wall tabs 16, 17.

Zur exakten Führung der Materialbahn 47 bzw. Zuschnitte 12, 13 im Bereich der Einschubstation 28 ist zwischen den Walzenförderern 56, 57, nämlich im Bereich der Führungsmulde 67, ein weiteres Führungs- und Förderorgan angeordnet. Dieses besteht zum einen aus einer im Takt der übrigen Förderorgane drehend angetriebenen Führungswalze 68, die zentrisch in der Führungsmulde 67 gelagert ist. Die Führungswalze 68 ist mit mehreren, parallelen und ringsherum laufenden Eindrehungen 69 versehen. Für die Anlage der Materialbahn 47 sind dadurch mehrere, in Axialrichtung mit Abstand voneinander angeordnete Walzenabschnitte 70 vorgesehen. Diese sind jeweils mit einer an der Umfangsfläche mündenden Saugbohrung 71 ausgestattet, die die Materialbahn 47 bzw. die Zuschnitte 12, 13 auf den Walzenabschnitten 70 fixiert. Die Saugbohrungen 71 sind an eine zentrische Saugleitung 72 angeschlossen, die im Bereich des Drehlagers der Führungswalze 68 über einen Saugring 73 mit einem Saugleitungsanschluß 74 verbunden ist.For the exact guidance of the material web 47 or blanks 12, 13 in the region of the insertion station 28, a further guiding and conveying element is arranged between the roller conveyors 56, 57, namely in the region of the guiding trough 67. On the one hand, this consists of a guide roller 68 which is driven in rotation with the cycle of the other conveying members and which is mounted centrally in the guide trough 67. The guide roller 68 is provided with a plurality of parallel rotations 69 running all around. As a result, a plurality of roller sections 70 arranged at a distance from one another in the axial direction are provided for the contact of the material web 47. These are each equipped with a suction bore 71 opening on the peripheral surface, which fixes the material web 47 or the blanks 12, 13 on the roller sections 70. The suction bores 71 are connected to a central suction line 72 which is connected to a suction line connection 74 in the region of the rotary bearing of the guide roller 68 via a suction ring 73.

Der Führungswalze 68 zugeordnet ist ein feststehender Gegenkörper 75. Dieser ist mittig zwischen den Walzenförderern 56, 57 angeordnet. Der untere Bereich ist bogenförmig ausgebildet und an die Abmessung der Führungswalze 68 angepaßt. Der Gegenkörper 75 ist hier kammartig ausgebildet mit nach beiden Seiten gerichteten Fingern 76, 77. Diese treten in die Eindrehungen 69 zwischen den Walzenabschnitten 70 der Führungswalze 68 ein und bewirken, daß die Materialbahn 47 bei der Vorschubbewegung korrekt geführt wird, nämlich vom Umfang des ersten Walzenförderers 56 an die Führungswalze 68 übergeben und von dieser auf den zweiten Walzenförderer 57 geleitet wird. Der Gegenkörper 75 hat dabei auch Abstreiferfunktion.A fixed counter body 75 is assigned to the guide roller 68. This is arranged centrally between the roller conveyors 56, 57. The lower area is arcuate and adapted to the dimensions of the guide roller 68. The counter body 75 is comb-like here with fingers 76, 77 directed towards both sides. These enter the indentations 69 between the roller sections 70 of the guide roller 68 and cause the material web 47 to be correctly guided during the feed movement, namely from the circumference of the first Transfer roller conveyor 56 to the guide roller 68 and is guided by this to the second roller conveyor 57. The counter body 75 also has a wiper function.

Die Materialbahn (47) bzw. die Zuschnitte (12, 13) umschlingen die Walzenförderer (56, 57) und die Führungswalze (68) um mehr als die Hälfte. Der Trennschnitt (53) zur Teilung der beiden Zuschnitte (12, 13) voneinander liegt im Bereich der Führungswalze (68), etwas außermittig, so daß bei der Übernahme der Zuschnitte (12,13) durch die zugeordneten Zigaretten-Packungen (10) die Zuschnitte (12, 13) schlupfend einerseits von den Walzenförderern (56, 57) und andererseits in entgegengesetzten Richtungen von der Führungswalze (68) abgezogen werden.The material web (47) or the blanks (12, 13) loop around the roller conveyors (56, 57) and the guide roller (68) by more than half. The separating cut (53) for dividing the two blanks (12, 13) lies from one another in the area of the guide roller (68), somewhat off-center, so that when the blanks (12, 13) are taken over by the associated cigarette packs (10), the blanks (12, 13) slip on the one hand from the roller conveyors (56, 57) and on the other hand, be pulled in opposite directions from the guide roller (68).

Der stark geschwungene Verlauf der Materialbahn 47 bzw. der Zuschnitte 12, 13 ist besonders aus Fig. 6 ersichtlich. Durch diese Formgebung der Materialbahn 47 ist es möglich, die gemeinsam auszuschiebenden Zigaretten-Packungen 10 in geringem Abstand voneinander anzuordnen, trotz der beträchtlichen Abmessung der Zuschnitte 12, 13 in Förderrichtung. Die Anordnung der Förderwalzen 50, 56, 57 und 68 relativ zueinander ist derart, daß die Materialbahn 47 unmittelbar von dem Umfang einer Förderwalze an die andere übergeben wird. Jede dieser Förderwalzen ist mit radial gerichteten Saugbohrungen 55 und 71 bzw. 78 und 79 versehen, die jeweils einen in Förderrichtung vornliegenden Randbereich der Materialbahn 47 bzw. der Zuschnitte 12, 13 erfassen und so den Transport sichern. Bei der Übergabe eines Zuschnitts 12, 13 von einer dieser Förderwalzen an die nächste kommen die Saugbohrungen momentan in eine benachbarte Relativstellung (in Fig. 6 beim Walzenförderer 56 und der Führungswalze 68). Während der Phase des Übergangs wird die bis dahin den Zuschnitt 13 haltende Saugbohrung 78 kurzzeitig entlüftet, so daß der Zuschnitt zuverlässig an die nächste Förderwalze übergeben wird. Die Walzenförderer 56, 57 sind dabei jeweils nur mit einzelnen Saugbohrungen 78, 79 im Bereich der Saugscheiben 58, 59 versehen. Die Messerwalze 50 ist mit einer in Axialrichtung durchlaufenden Reihe von Saugbohrungen 55 ausgerüstet (Fig. 5).The strongly curved course of the material web 47 or the blanks 12, 13 is particularly evident from FIG. 6. This shape of the material web 47 makes it possible to arrange the cigarette packs 10 to be pushed out together at a short distance from one another, despite the considerable dimensions of the blanks 12, 13 in the conveying direction. The arrangement of the conveyor rollers 50, 56, 57 and 68 relative to one another is such that the material web 47 is transferred directly from the circumference of one conveyor roller to the other. Each of these conveyor rollers is provided with radially directed suction bores 55 and 71 or 78 and 79, each of which grips an edge region of the material web 47 or of the blanks 12, 13 lying forward in the conveying direction and thus secures the transport. When a blank 12, 13 is transferred from one of these conveyor rollers to the next, the suction bores momentarily come into an adjacent relative position (in FIG. 6 with the roller conveyor 56 and the guide roller 68). During the phase of the transition, the suction bore 78 holding the blank 13 up to that point is briefly vented, so that the blank is reliably transferred to the next conveyor roller. The roller conveyors 56, 57 are each provided with individual suction bores 78, 79 in the area of the suction disks 58, 59. The knife roller 50 is equipped with a row of suction bores 55 running through in the axial direction (FIG. 5).

Das System der Saugbohrungen ist im wesentlichen in herkömmlicher Weise ausgebildet. Die Saugbohrungen sind dabei mit innerhalb der Förderwalzen achsparallel verlaufenden Saugleitungen 80 verbunden. Diese münden an den Stirnenden der Förderwalzen an unverdrehbar gelagerten Saugscheiben 81, in Fig. 5 anhand des Walzenförderers 56 im Schnitt gezeigt. Die Saugscheiben 81 werden jeweils durch Druckfedern 82 gleitend und dichtend an die zugekehrten Stirnflächen der Förderwalzen gedrückt. Die Saugscheiben 81 sind weiterhin mit kreisförmigen Saugnuten 83 versehen, die zu den Stirnflächen der Förderwalzen offen sind und mit denen die Enden der Saugleitungen 80 während der Drehbewegung der Förderwalzen zeitweilig zur Überdeckung kommen. Während dieser Überdeckungsphase wird Saugluft übertragen. Die Länge der Saugnuten 83 entspricht demnach der Dauer der Saugphase. Benachbart zu den Saugnuten 83, jedoch außerhalb derselben, ist, wo erforderlich, eine Entlüftungsbohrung 84 angebracht, und zwar auf demselben Kreisbogen wie die Saugnuten 83, so daß die Saugleitung 80 während einer kurzen Phase der Drehbewegung mit der Entlüftungsbohrung 84 zur Überdeckung kommt und dadurch die bereits beschriebene Entlüftung der Saugbohrungen bewirkt. Fig. 7 zeigt die Relativstellung der Saugnuten 83 und Entlüftungsbohrungen 84 für die Förderwalzen 50, 56, 57 und 68.The system of suction bores is essentially designed in a conventional manner. The suction bores are axially parallel within the conveyor rollers Suction lines 80 connected. These open at the front ends of the conveyor rollers on non-rotatably mounted suction disks 81, shown in section in FIG. 5 by means of the roller conveyor 56. The suction disks 81 are each pressed by pressure springs 82 in a sliding and sealing manner against the facing end faces of the conveyor rollers. The suction disks 81 are also provided with circular suction grooves 83 which are open to the end faces of the conveyor rollers and with which the ends of the suction lines 80 temporarily overlap during the rotational movement of the conveyor rollers. Suction air is transmitted during this overlap phase. The length of the suction grooves 83 therefore corresponds to the duration of the suction phase. Adjacent to, but outside of, the suction grooves 83, a vent hole 84 is provided, where necessary, on the same circular arc as the suction grooves 83, so that the suction line 80 overlaps with the vent hole 84 during a brief phase of the rotational movement and thereby the already described ventilation of the suction bores causes. Fig. 7 shows the relative position of the suction grooves 83 and vent holes 84 for the conveyor rollers 50, 56, 57 and 68.

Vor dem Einschub der Zigaretten-Packungen 10 in die beiden Taschen 30, 31 des Faltrevolvers 29 treten die Zigaretten-Packungen 10 mit den Zuschnitten 12, 13 durch ein Mundstück hindurch, welches durch feststehende Außenwände 85, 86 einerseits und durch den entsprechend geformten Gegenkörper 75 andererseits gebildet ist.Before the cigarette packs 10 are inserted into the two pockets 30, 31 of the folding turret 29, the cigarette packs 10 with the blanks 12, 13 pass through a mouthpiece which passes through fixed outer walls 85, 86 on the one hand and through the correspondingly shaped counter body 75 on the other hand is formed.

In den durch jeweils zwei Taschenwandungen 87, 88 gebildeten Taschen 30, 31 werden die Zigaretten-Packungen 10 so gehalten, daß die Seitenwandlappen 16,17 aus den Taschen 30, 31 herausragen. Unmittelbar im Bereich der Einschubstation 28 treten nun erste Faltorgane in Aktion, nämlich konzentrisch zum Faltrevolver 29 angeordnete und hin- und herschwenkbare Seitenfalter 89 und 90. Durch den Seitenfalter 89 wird zunächst der kürzere, innenliegende Seitenwandlappen 17 der in Drehrichtung des Faltrevolvers 29 rückwärtigen Taschen 30 umgefaltet. Durch entsprechende Schwingbewegung des Seitenfalters 90 wird zugleich der innere Seitenwandlappen 17 der benachbarten Tasche 31 umgefaltet. Bei der nun beginnenden Drehbewegung des Faltrevolvers 29 wird der längere, äußere Seitenwandlappen 16 der Tasche 31 durch die Kante einer ortsfesten äußeren Führungswand 91 des Faltrevolvers 29 umgefaltet. Der entsprechende Seitenwandlappen 17 der Zigaretten-Packung 10 in der benachbarten Tasche 30 wird durch den Seitenfalter 90 in gleicher Weise gefaltet. Die genannten Seitenfalter 89, 90 sind auf einer Revolverwelle 92 des Faltrevolvers 29 gelagert und werden durch Schubstangen 93 schwingend betätigt.The cigarette packs 10 are held in the pockets 30, 31 formed by two pocket walls 87, 88 in such a way that the side wall tabs 16, 17 protrude from the pockets 30, 31. Immediately in the area of the insertion station 28, first folding members come into action, namely, side folders 89 and 90 which are arranged concentrically to the folding turret 29 and can be pivoted back and forth 89, the shorter, inner side wall tab 17 of the pockets 30 rearward in the direction of rotation of the folding turret 29 is first folded over. The inner side wall tab 17 of the adjacent pocket 31 is simultaneously folded over by a corresponding oscillating movement of the side folder 90. When the folding turret 29 begins to rotate, the longer, outer side wall tab 16 of the pocket 31 is folded over by the edge of a stationary outer guide wall 91 of the folding turret 29. The corresponding side wall tab 17 of the cigarette pack 10 in the adjacent pocket 30 is folded in the same way by the side folder 90. The side folders 89, 90 mentioned are mounted on a turret shaft 92 of the folding turret 29 and are actuated in a swinging manner by push rods 93.

Bereits bei der Einschubbewegung der Zigaretten-Packungen 10 mit den Zuschnitten 12, 13 in die Taschen 30, 31 erfolgt der erste Faltvorgang, nämlich das Einfalten der in Einschubrichtung vornliegenden Seitenendlappen 20 durch Faltfinger 94 als seitliche Begrenzung der Taschen 30, 31. Die Faltung erfolgt dabei durch Relativbewegung der Zigaretten-Packungen 10 zu diesen Faltfingern 94. Zur Fixierung der danach seitlich abstehenden Längslappen 22, 23 sind die Faltfinger 94 an den in Drehrichtung des Faltrevolvers 29 weisenden Seitenflächen mit Saugbohrungen 95 versehen. Die Faltfinger 94 bilden zugleich die seitlichen Begrenzungen der Taschen 30, 31. Weitere Saugbohrungen 96 münden im Bereich von Stirnflächen 97 der Faltfinger 94. Durch die Saugbohrungen 96 werden die Zuschnitteile zur Bildung der gegenüberliegenden Seitenendlappen 21 in ihrer quergerichteten Position gehalten. Durch die Saugbohrungen 96 wird zugleich der innenliegende Seitenwandlappen 17 in seiner Position gehalten und damit die überlappende Stellung der beiden Seitenwandlappen 16, 17 stabilisiert. Die Saugbohrungen 95, 96 sind an ein System von Saugkanälen 98 innerhalb des Faltrevolvers angeschlossen. Über einen zentralen Segmentring 99 werden die Saugkanäle 98 und damit die Saugbohrungen 95, 96 in der beschriebenen Weise mit Saugluft versorgt.Already during the insertion movement of the cigarette packs 10 with the blanks 12, 13 into the pockets 30, 31, the first folding process takes place, namely the folding in of the side end flaps 20 lying in the direction of insertion by folding fingers 94 as a lateral limitation of the pockets 30, 31. The folding takes place thereby by relative movement of the cigarette packs 10 to these folding fingers 94. In order to fix the laterally projecting longitudinal tabs 22, 23, the folding fingers 94 are provided with suction bores 95 on the side surfaces pointing in the direction of rotation of the folding turret 29. The folding fingers 94 also form the lateral boundaries of the pockets 30, 31. Further suction bores 96 open out in the region of end faces 97 of the folding fingers 94. The suction bores 96 hold the cut parts in their transverse position to form the opposite side end tabs 21. The inner side wall tab 17 is simultaneously held in position by the suction bores 96 and thus the overlapping position of the two side wall tabs 16, 17 is stabilized. The suction bores 95, 96 are connected to a system of suction channels 98 within the folding turret. Via a central Segment ring 99, the suction channels 98 and thus the suction bores 95, 96 are supplied with suction air in the manner described.

Im Bereich einer ersten Siegelstation 100 werden die einander überlappenden Seitenwandlappen 16, 17 durch ein gabelförmiges Siegelorgan 101 unter Anwendung von Wärme und Druck gesiegelt. Dieser Vorgang wiederholt sich nach dem Weiterschalten des Faltrevolvers in einer zweiten Siegelstation 102 mit einem weiteren Siegelorgan 103.In the area of a first sealing station 100, the overlapping side wall tabs 16, 17 are sealed by a fork-shaped sealing member 101 using heat and pressure. This process is repeated after the folding turret has been indexed in a second sealing station 102 with a further sealing member 103.

In der nach erneuter Schaltung des Faltrevolvers 29 erreichten Ausschubstation 32 werden die Zigaretten-Packungen 10 durch einen gemeinsamen winkelförmigen Ausschieber 104 aus den Taschen 30, 31 heraus- und in die Abförderbahn 33 eingeschoben. Beim Austritt der Zigaretten-Packungen 10 aus den Taschen 30, 31 erfolgt das Umfalten der in Radialrichtung außenliegenden Seitenendlappen 21 durch feststehende Faltdaumen 105 an der Eintrittsseite der Abförderbahn 33.In the ejection station 32 that is reached after the folding turret 29 has been switched on again, the cigarette packs 10 are pushed out of the pockets 30, 31 by a common angular ejector 104 and inserted into the discharge path 33. When the cigarette packs 10 emerge from the pockets 30, 31, the side end flaps 21 lying outside in the radial direction are folded over by fixed folding thumbs 105 on the entry side of the discharge conveyor track 33.

Während des Transports der Zigaretten-Packungen 10 in der Abförderbahn 33 werden die nun noch seitlich überstehenden Längslappen 22, 23 gefaltet, und zwar durch bekannte Faltweichen oder andere Faltorgane.During the transport of the cigarette packs 10 in the discharge conveyor 33, the longitudinal tabs 22, 23 which now still protrude laterally are folded, namely by known folding switches or other folding members.

Die in Fig. 8 gezeigte Lösung entspricht weitgehend der beschriebenen. Gegenüber den Einzelheiten gemäß Fig. 2 und 4 sind bei Fig. 8 in der Bewegungsbahn der Zigaretten-Packungen 10 zu den Taschen 30, 31 des Faltrevolvers 29 feststehende Faltdaumen 110 zu beiden Seiten der Bewegungsbahn angeordnet, derart, daß bei der Vorbeibewegung der Zigaretten-Packungen 10 die in Bewegungsrichtung vornliegenden Seitenendlappen 20 vorgefaltet werden. Der Gegenkörper 75 sowie die seitlich angeordneten Außenwände 85 und 86 sind entsprechend länger ausgebildet.The solution shown in Fig. 8 largely corresponds to that described. Compared to the details according to FIGS. 2 and 4, in FIG. 8, in the movement path of the cigarette packs 10 to the pockets 30, 31 of the folding turret 29, fixed folding thumbs 110 are arranged on both sides of the movement path, such that when the cigarette packs are moved past Packs 10 are the pre-folded side end flaps 20 in the direction of movement. The counter body 75 and the laterally arranged outer walls 85 and 86 are correspondingly longer.

Die Förderorgane, nämlich die Zugwalzen (48, 49), die Messerwalze (50), die Walzenförderer (56, 57) und die Führungswalze (68) sind seitlich in Tragwangen (106, 107) gelagert. Der Antrieb erfolgt über eine Antriebswelle (108) über eine Mehrzahl von in sinnvoller Weise miteinander kämmenden Zahnrädern (109).The conveying elements, namely the pull rollers (48, 49), the knife roller (50), the roller conveyors (56, 57) and the guide roller (68) are mounted laterally in carrying cheeks (106, 107). The drive takes place via a drive shaft (108) via a plurality of gearwheels (109) which mesh in a meaningful manner.
