Bedruckungen an freien Außenflächen von Zigarettenpackungen mittels Druckwerk, insbesondere Laser-Codierer, wobei das Druckwerk ortsfest neben einem Endlosförderer für die Zigarettenpackungen positioniert ist, wobei die Packungen mit einer dem Druckwerk zugekehrten, mindestens teilweise freien, vom Endlosförderer nicht bedeckten Außenfläche der Packung vorbeibewegt werden und wobei während der Förderbewegung oder während zeitweiligen Stillstands der Packungen die Bedruckung an der freien bzw. am freien Teil der Außenfläche der Packung angebracht wird. Weiterhin betrifft die Erfindung eine Vorrichtung zur Durchführung des Verfahrens.The invention relates to a method for attaching markings or imprints on free outer surfaces of cigarette packs by means of printing unit, in particular laser encoder, wherein the printing unit is stationarily positioned next to an endless conveyor for the cigarette packs, the packs facing the printing unit, at least partially free are moved past the outer surface of the pack not covered by the endless conveyor, and wherein during the conveying movement or during temporary stoppage of the packs the printing is applied to the free or to the free part of the outer surface of the pack. Furthermore, the invention relates to a device for carrying out the method.

Das Anbringen von informativen Bedruckungen und/oder von Codierungen gewinnt insbesondere bei Zigarettenpackungen zunehmend Bedeutung. Es ist wichtig, den Vorgang der Bedruckung in den Arbeitsprozess der Verpackungsmaschine zu integrieren. Dabei haben Laser-Drucker bzw. Laser-Codierer bisher die besten Ergebnisse erbracht. Die mit der Bedruckung bzw. Codierung versehene Fläche an der Außenseite der Zigarettenpackung ist mit einer Beschichtung versehen, die durch den Laser-Codierer teilweise abgetragen wird.The application of informative imprints and / or encodings is becoming increasingly important, in particular for cigarette packs. It is important to integrate the process of printing into the working process of the packaging machine. Laser printers and laser encoders have yielded the best results so far. The surface provided with the printing or coding on the outside of the cigarette pack is provided with a coating which is partially removed by the laser encoder.

Aus der Druckschrift GB 2 337 974 ist bekannt, Fördergurte eines Förderbands zum Stabilisieren von Zigarettenpackungen so schmal auszubilden, dass die an den Gurten anliegende Seitenfläche der Zigarettenpackungen frei liegen und an dieser Seite mittels eines Lasers markiert werden können. Nachteiligerweise ist es dabei notwendig, die Gurtbreite an die Packungsbreite anzupassen, d.h. entsprechend schmaler auszuführen.From the publication GB 2 337 974 It is known to form conveyor belts of a conveyor belt for stabilizing cigarette packets so narrow that the voltage applied to the straps side surface of the cigarette packs are exposed and can be marked on this page by means of a laser. Disadvantageously, it is necessary to adapt the belt width to the package width, ie to make it correspondingly narrower.

Der Erfindung liegt die Aufgabe zugrunde, das Anbringen von Markierungen oder Codierungen an (Zigaretten-)Packungen so auszugestalten, dass Verfahren und Vorrichtung in den Arbeitsprozess der Verpackungsmaschine integriert sind und keine gesonderten Maßnahmen erfordern.The object of the invention is to design the attachment of markings or codings to (cigarette) packs such that the method and apparatus are integrated into the working process of the packaging machine and do not require any separate measures.

Diese Aufgabe wird gelöst durch ein Verfahren mit den Merkmalen des Anspruches 1 sowie eine Vorrichtung mit den Merkmalen des Anspruches 5.This object is achieved by a method having the features of claim 1 and a device having the features of claim 5.

Erfindungsgemäß werden die Packungen so transportiert, dass eine von den Förderorganen nicht erfasste bzw. bedeckte Packungsfläche dem Drucker bzw. Laser-Codierer zugekehrt ist. Die Förderung der Zigarettenpackungen erfolgt dabei in Packungsgruppen. Vorteilhafterweise sind die Packungsflächen im Bereich einer Station dem Laser-Codierer zugekehrt und dieser versieht gleichzeitig mehrere Packungen im Bereich der betreffenden Fläche mit Bedruckung bzw. Codierung. Dabei sind Maßnahmen vorgesehen zum exakten Ausrichten der Packungen bzw. der zu bedruckenden Flächen. Der Förderer für die Zigarettenpackung kann ein Trockenrevolver sein mit Taschen zur Aufnahme jeweils einer Packungsgruppe, bei der Stirnflächen radial nach außen gerichtet und zur Bedruckung freiliegen.According to the invention, the packages are transported in such a way that a packing area not covered or covered by the conveying members faces the printer or laser encoder. The promotion of the cigarette packs takes place in pack groups. Advantageously, the packaging surfaces in the region of a station facing the laser encoder and this provides simultaneously several packages in the region of the surface concerned with printing or coding. Measures are provided for the exact alignment of the packages or the surfaces to be printed. The conveyor for the cigarette pack may be a dry turret with pockets for accommodating one pack group, directed at the end faces radially outward and exposed for printing.

Fig. 1 zeigt das wichtigste Anwendungsbeispiel für die Codierung von Packungen 10, nämlich eine Zigarettenpackung des Typs Klappschachtel. Diese besteht bekanntermaßen aus einem Schachtelteil 11 und einem Deckel 12. Die Packung 10 hat eine quaderförmige Gestalt mit einer großflächigen Frontseite 13, schmalen, aufrechten Seitenflächen 14 und nochmals kleineren Endflächen, nämlich Stirnfläche 15 und Bodenfläche 16. Fig. 1 shows the most important application example for the coding of packages 10, namely a cigarette pack of the folding box type. This is known to consist of a box part 11 and a lid 12. The package 10 has a cuboid shape with a large-scale front side 13, narrow, upright side surfaces 14 and even smaller end surfaces, namely end face 15 and bottom surface 16th

Die Packung 10 soll mit einer äußeren Bedruckung versehen werden, und zwar insbesondere mit einer Codierung, z.B. aus Ziffern. Buchstaben und/oder Strichen. Die Codierung wird mittels Laser angebracht. Zu diesem Zweck sind ausgewählte Außenflächen der Packung 10 mit Codierungsflächen 17, 18 versehen. Es handelt sich dabei um streifenförmige, äußere Beschichtungen der Packungen 10, die beim Bedrucken bzw. Codieren durch den Laser teilweise abgetragen werden, unter Bildung der Buchstaben, Ziffern oder Strichen. Bei der Darstellung in Fig. 1 sind mehrere Alternativen für die Anbringung der Codierungsflächen 17, 18 gezeigt. Bevorzugt sind die einander gegenüberliegenden schmalen, aufrechten Seitenflächen 14, und zwar im Bereich benachbart zur Bodenfläche 16 und/oder im Bereich des Deckels 12 benachbart zur Stirnfläche 15. Alternativ oder zusätzlich können entsprechende Codierungsflächen 17, 18 im Bereich von Stirnfläche 15 und Bodenfläche 16 angeordnet sein, und zwar jeweils benachbart zu einer angrenzenden Fläche, also benachbart und parallel zu einer Packungskante.The package 10 should be provided with an external printing, in particular with a Coding, eg from numbers. Letters and / or lines. The coding is attached by laser. For this purpose, selected outer surfaces of the pack 10 are provided with coding surfaces 17, 18. These are strip-shaped, outer coatings of the packs 10, which are partially removed during printing or coding by the laser, forming the letters, numbers or lines. When displayed in Fig. 1 Several alternatives for the attachment of the coding surfaces 17, 18 are shown. Preferably, the opposing narrow, upright side surfaces 14, in the region adjacent to the bottom surface 16 and / or in the region of the lid 12 adjacent to the end face 15. Alternatively or additionally, corresponding coding surfaces 17, 18 in the region of the end face 15 and bottom surface 16 are arranged be, in each case adjacent to an adjacent surface, ie adjacent and parallel to a pack edge.

Es sind mehrere vorteilhafte Lösungen aufgezeigt für die Anbringung der Codierung im Bereich die Codierungsflächen 17 oder 18. In allen Fällen sind die Packungen 10 bereits fertig gestellt und werden ggf. noch mit einer äußeren Folienumhüllung versehen.There are several advantageous solutions shown for the attachment of the coding in the area of the coding surfaces 17 or 18. In all cases, the packs 10 are already completed and are possibly still provided with an outer film wrapping.

Bei dem Ausführungsbeispiel gemäß Fig. 2 ist ein Bedruckungsaggregat bzw. ein Laser-Codierer 19 im Bereich einer Förderstrecke für die Packungen positioniert. Die Packungen 10 werden dabei so transportiert, dass Stirnfläche 15 und Bodenfläche 16 seitwärts gerichtet sind und eine der Seitenflächen 14 nach oben weist. Die Packungen 10 werden mit Abstand voneinander gefördert, und zwar durch Endlosförderer, die im Bereich der seitwärts gerichteten Flächen angreifen. Es handelt sich dabei um zwei der Höhe nach im Abstand voneinander verlaufende (Flach-)Gurte 20, 21. Die nach oben gerichtete Packungsfläche, also die Seitenfläche 14, liegt völlig frei. Der Laser-Codierer 19 kann demnach die im Bereich der Seitenfläche 14 angeordneten Codierungsflächen 17, 18 während des Transports der Packungen 10 oder während eines zeitweiligen Stillstands derselben mit einer Codierung versehen.In the embodiment according to Fig. 2 is a printing unit or a laser encoder 19 positioned in the region of a conveying path for the packs. The packs 10 are transported so that the end face 15 and bottom surface 16 are directed sideways and one of the side surfaces 14 facing upward. The packages 10 are conveyed at a distance from each other, by endless conveyors, which attack in the region of the sideways surfaces. These are two (flat) straps 20, 21 that extend at a distance from one another. The upward-facing packing surface, that is to say the side surface 14, is completely free. Accordingly, the laser encoder 19 can code the coding surfaces 17, 18 located in the area of the side surface 14 during the transport of the packs 10 or during a temporary standstill thereof.

Die Vorrichtung gemäß Fig. 2 ist Teil einer Verpackungsmaschine, dient nämlich vorrangig zur Prüfung der Packungen 10 hinsichtlich korrekter Ausgestaltung. Die Gurte 20, 21 bilden eine Prüfstrecke, in deren Bereich Prüforgane angeordnet sind, nämlich Kameras 22, 23. Diese erfassen das äußere Erscheinungsbild der Packung 10 und prüfen deren korrekte Ausbildung, im vorliegenden Falle auch hinsichtlich der Codierung. Der Laser-Codierer 19 ist demnach in Förderrichtung der Packungen 10 vor der Prüfstation bzw. vor den Kameras 22, 23 angeordnet, so dass diese die korrekte Codierung mit überprüfen können. Im Übrigen ist die Prüfvorrichtung zweckmäßigerweise nach Maßgabe von EP 854 090 ausgebildet. Zum Beseitigen von etwaigen Materialpartikeln im Bereich der Codierung ist bei diesem Ausführungsbeispiel ein Saugorgan 24 positioniert, welches während der Codierung einer Packung 10 an eine Unterdruckquelle angeschlossen ist.The device according to Fig. 2 is part of a packaging machine, namely primarily for testing the packages 10 in terms of correct design. The straps 20, 21 form a test track, in the area of which test elements are arranged, namely cameras 22, 23. These detect the external appearance of the pack 10 and check their correct formation, in this case also with regard to the coding. The laser encoder 19 is therefore arranged in the conveying direction of the packs 10 in front of the test station or in front of the cameras 22, 23, so that they can check the correct coding with. Moreover, the test device is expediently in accordance with EP 854 090 educated. In order to remove any material particles in the area of the coding, in this embodiment a suction member 24 is positioned, which is connected to a vacuum source during the coding of a pack 10.

Wie aus Fig. 3 ersichtlich, kann ein Druckaggregat bzw. ein Laser-Codierer 19 bei einer Vorrichtung gemäß Fig. 2 im Bereich der Gurte 20, 21 auch so angebracht werden, dass seitwärts gerichtete Flächen der Packung 10 mit einer Codierung versehen werden können, also Stirnfläche 15 oder Bodenfläche 16. Der Laser-Codierer 19 ist entsprechend der strichpunktierten Darstellung seitlich neben der Bewegungsbahn der Packungen 10 positioniert. Ein Laserstrahl ist dabei auf einen freien Bereich der Stirnfläche 15 bzw. Bodenfläche 16 gerichtet, im vorliegenden Falle oberhalb des oberen Gurts 20.How out Fig. 3 can be seen, a printing unit or a laser encoder 19 in a device according to Fig. 2 in the region of the straps 20, 21 are also mounted so that laterally facing surfaces of the pack 10 can be provided with a coding, ie end face 15 or bottom surface 16. The laser encoder 19 is according to the dash-dotted representation laterally next to the trajectory of the packs 10th positioned. A laser beam is directed onto a free region of the end face 15 or bottom surface 16, in this case above the upper belt 20.

Die Vorrichtung gemäß Fig. 4 befindet sich ebenfalls im Endbereich einer Verpackungsmaschine. Es handelt sich dabei um eine Sammel- und Fördervorrichtung für Packungen 10 in weitgehender Übereinstimmung mit EP 596 387 .The device according to Fig. 4 is also located in the end of a packaging machine. It is a collection and conveying device for packs 10 in broad agreement with EP 596,387 ,

Die Packungen 10 werden mit Abstand voneinander durch einen horizontalen Packungsförderer 25 transportiert. Dieser besteht aus einem oberen Förderband 26 und einem unteren Förderband 27. Die Packungen 10 werden jeweils von einem Obertrum und einem Untertrum im Bereich von nach oben und unten weisenden Packungsflächen erfasst, und zwar im Bereich der entsprechend positionierten Seitenflächen 14.The packages 10 are transported at a distance from each other by a horizontal pack conveyor 25. This consists of an upper conveyor belt 26 and a lower conveyor belt 27. The packs 10 are each detected by an upper run and a lower run in the region of up and down facing pack surfaces, in the region of the correspondingly positioned side surfaces 14th

Die Packungen sollen an einen Vertikalförderer 28 übergeben werden. Dieser ist so ausgebildet, dass an einem aufrechten Endlosförderer 29 quer abstehende Plattformen 30 mit Abstand voneinander angeordnet sind. Diese erfassen jeweils mehrere, nämlich zwei Packungen 10 und transportieren diese aufwärts.The packages are to be transferred to a vertical conveyor 28. This is designed so that on an upright endless conveyor 29 transversely projecting platforms 30 are arranged at a distance from each other. These each detect several, namely two packs 10 and transport them upwards.

Der Packungsförderer 25 endet bei dieser Vorrichtung mit Abstand von dem Vertikalförderer 28. Die Packungen 10 werden hier zu einer Dichtreihe 31 formiert. Diese wird durch jeweils nachfolgende Packungen 10 über eine Brückenplatte 32 dem Vertikalförderer 28 zugeführt. Im Bereich dieser letzten Förderstrecke, nämlich der Brückenplatte 32, sind die Packungen 10 an der Oberseite frei, so dass die nach oben gerichtete Packungsfläche - Seitenfläche 14 - durch einen im Anschluss an den Packungsförderer 25 oberhalb der Packungen 10 positionierten Laser-Codierer 19 mit der Codierung versehen werden kann. Zusätzlich oder alternativ kann bei dieser Vorrichtung ein Laser-Codierer auch seitwärts neben dem Packungsförderer 25 positioniert sein, wenn die seitwärts gerichteten freien Packungsflächen, nämlich Stirnfläche 15 oder Bodenfläche 16, mit einer Codierung versehen werden sollen.The packing conveyor 25 ends in this device at a distance from the vertical conveyor 28. The packs 10 are formed here to a row of seals 31. This is fed to the vertical conveyor 28 by respective subsequent packages 10 via a bridge plate 32. In the area of this last conveyor line, namely the bridge plate 32, the packages 10 are free at the top, so that the upwardly directed packing surface - side surface 14 - by a subsequent to the package conveyor 25 above the packs 10 positioned laser encoder 19 with the Coding can be provided. Additionally or alternatively, in this device, a laser encoder may also be positioned sideways next to the package conveyor 25, when the laterally directed free packing surfaces, namely face 15 or bottom surface 16, are to be provided with a coding.

Ein wichtiges Ausführungsbeispiel zeigen Fig. 5 und Fig. 6. Die Packungen 10 werden als Packungsgruppe 54 in Taschen 33 eines Revolvers 34 transportiert. Bei diesem handelt es sich um einen Trockenrevolver etwa in der Ausführung von US 4 636 186 . Aufgabe des Revolvers 34 ist es, die Packungen 10 bzw. Packungsgruppen 54 während einer gewissen Zeit zu transportieren, damit Leimstellen der Packungen unter Aufrechterhaltung einer korrekten Form aushärten können.An important embodiment show Fig. 5 and Fig. 6 , The packs 10 are transported as a pack group 54 in pockets 33 of a revolver 34. This is a dry turret about in the execution of US 4 636 186 , The task of the revolver 34 is to transport the packs 10 or groups of packs 54 for a certain time so that glue spots of the packs can be cured while maintaining a correct shape.

Die Taschen 33 sind so ausgebildet, dass die Packungen 10 einer Packungsgruppe 54 in Axialrichtung nebeneinander angeordnet sind, im vorliegenden Falle sechs Packungen 10 als Packungsgruppe 54. Die Taschen 33 sind an beiden axialen Seiten offen, so dass im Bereich einer Beschickungsstation 35 die Packungen 10 in achsparalleler Richtung durch einen Zuförderer 36 in eine jeweils freie Tasche 33 einführbar sind. An einer in Umfangsrichtung versetzten Position ist eine Ausschubstation 37 gebildet, in der gleichzeitig mit der Beschickung einer Packungsgruppe 54 aus einer Tasche 33 ebenfalls in achsparalleler Richtung ausgeschoben wird. Hierzu dient ein in entsprechender Richtung hin- und herbewegbarer Schieber 38, der über einen Tragarm 39 mit einem Betätigungsgetriebe, nämlich einer Kurbel 40, verbunden ist.The pockets 33 are designed such that the packs 10 of a pack group 54 are arranged next to one another in the axial direction, in the present case six packs 10 as a pack group 54. The pockets 33 are open on both axial sides, so that in the region of a feed station 35 the packs 10 can be inserted in an axially parallel direction by a feed conveyor 36 in a respective free pocket 33. At an offset position in the circumferential direction, a Ausschubstation 37 is formed in the same time as the loading of a packing group 54 is pushed out of a pocket 33 also in the axis-parallel direction. For this purpose, a slide 38 which can be moved back and forth in a corresponding direction and which is connected via a support arm 39 to an actuating gear, namely a crank 40, is used.

Die Taschen 33 sind in besonderer Weise ausgebildet, bestehen nämlich im Wesentlichen aus zwei seitlichen Taschenwänden 41, 42. Diese erfassen die Packungen 10 im Bereich der Seitenflächen 14. Die Stirnflächen 15 oder Bodenflächen 16 sind radial nach innen und außen gerichtet. Eine der Taschenwände, nämlich die Taschenwand 41, ist feststehend angeordnet und bildet mit einem radial innenliegenden Schenkel 43 eine innenseitige Begrenzung der Tasche 33 für die Packungen 10. Die andere, gegenüberliegende Taschenwand 42 ist schwenkbar um ein innenseitiges Lager 44. Durch Verschwenken der Taschenwand 42 wird demnach die Tasche 33 leicht geöffnet, um das Einschieben und Ausschieben der Packungen 10 störungsfrei zu ermöglichen.The pockets 33 are formed in a special way, namely consist essentially of two lateral pocket walls 41, 42. These capture the packs 10 in the region of the side surfaces 14. The end faces 15 or bottom surfaces 16 are directed radially inwardly and outwardly. One of the pocket walls, namely the pocket wall 41, is stationary and forms with a radially inner leg 43 an inside boundary of the bag 33 for the packs 10. The other, opposite pocket wall 42 is pivotable about an inside bearing 44. By pivoting the pocket wall 42nd Therefore, the bag 33 is slightly opened to allow the insertion and ejection of the packs 10 trouble-free.

Der (Trocken-)Revolver 34 ist als Förderer für die Packungen im Bereich eines Druckwerks bzw. Lasers besonders vorteilhaft. Die nach außen gerichteten Packungsflächen, nämlich Stirnflächen 15, können einem Laser-Codierer 19 (strichpunktiert in Fig. 5) unmittelbar zugekehrt sein, wobei der Laser-Codierer 19 zweckmäßigerweise in einer vertikalen Mittelebene des Revolvers 34 oberhalb desselben positioniert ist. Die dem Laser-Codierer 19 zugekehrte Packungsgruppe 54 wird in einem Arbeitstakt mit der Bedruckung bzw. Codierung versehen, wobei der Laserstrahl über bewegbare Spiegel entsprechend gelenkt wird. Es ist alternativ auch möglich, mehrere, insbesondere zwei Laser-Codierer in Axialrichtung nebeneinander anzuordnen, wobei jeder dieser Laser-Codierer eine Anzahl von Packungen 10 der Packungsgruppe 54 bearbeitet.The (dry) turret 34 is particularly advantageous as a conveyor for the packages in the area of a printing unit or laser. The outwardly directed packing surfaces, namely end faces 15, can be a laser encoder 19 (dash-dotted lines in Fig. 5 ) are directly facing, wherein the laser encoder 19 is advantageously positioned in a vertical center plane of the revolver 34 above the same. The group of packs 54 facing the laser encoder 19 is provided with the printing or coding in one working cycle, whereby the laser beam is deflected correspondingly via movable mirrors. Alternatively, it is also possible to arrange several, in particular two, laser encoders in the axial direction next to one another, wherein each of these laser encoders processes a number of packs 10 of the pack group 54.

Eine weitere Alternative ist ebenfalls in Fig. 5 und Fig. 6 gezeigt. Eine Taschenwand, nämlich im vorliegenden Falle die in Drehrichtung rückwärtige Taschenwand 42, ist mit einer geringeren radialen Abmessung ausgebildet als die der Packungen 10. Ein radial außenliegender Bereich der zugeordneten Seitenfläche 14 ragt über die Taschenwand 42 hinweg. In der entsprechenden, oberen Station kann so der Laser-Codierer 19 mit horizontalem Laserstrahl am freien Bereich der Seitenfläche 14 die Codierung anbringen.Another alternative is also in Fig. 5 and Fig. 6 shown. A pocket wall, namely in the present case the rearward in the direction of rotation pocket wall 42 is formed with a smaller radial dimension than that of the packs 10. A radially outboard portion of the associated side surface 14 projects beyond the pocket wall 42 away. In the corresponding upper station, the laser encoder 19 with a horizontal laser beam can thus attach the coding to the free area of the side surface 14.

Eine Besonderheit besteht darin, dass die Packungen 10 einer Packungsgruppe 54 während der Codierung exakt mindestens im Bereich der zu bedruckenden Flächen ausgerichtet sind. Fig. 5 und Fig. 6 zeigen diese Ausrichtung in der Hauptsache anhand der nach außen gerichteten Stirnflächen 15. Ein bewegbares Andrückorgan erstreckt sich über alle Packungen 10 der Packungsgruppe 54. Während der (Laser-)Bedruckung befinden sich demnach die Stirnflächen in einer gemeinsamen exakten Ebene.A special feature is that the packs 10 of a pack group 54 are aligned during the coding exactly at least in the area of the surfaces to be printed. Fig. 5 and Fig. 6 A movable pressing member extends over all packs 10 of the packing group 54. Accordingly, during (laser) printing, the end faces are located in a common exact plane.

Das Andrückorgan ist eine ortsfeste, drehbare Andrückwalze 55. Diese erstreckt sich in achsparalleler Richtung über die volle Länge der Packungsgruppe 54 bzw. über diese hinaus (Fig. 6). Die Andrückwalze 55 liegt in der Position des Ausrichtens versetzt zur Mittelebene an den Flächen bzw. Stirnflächen 15, derart, dass in einem daneben freibleibenden Bereich die LaserCodierung durchgeführt werden kann.The pressing member is a stationary, rotatable pressure roller 55. This extends in the direction parallel to the axis over the full length of the packing group 54 or beyond ( Fig. 6 ). The pressure roller 55 is in the position of alignment offset from the center plane on the surfaces or end faces 15, such that in a non-remaining area the laser coding can be performed.

Die Andrückwalze 55 ist so angeordnet bzw. bewegbar, dass ein Andrück- und Ausrichteffekt nur während der Phase der Codierung gegeben ist. Die Andrückwalze 55 ist deshalb hier als Exzenter ausgebildet bzw. an einem exzentrisch angeordneten Wellenzapfen 56 gelagert. Dieser wird drehend angetrieben, und zwar durch einen Antriebsgurt bzw. Zahnriemen 57, der seinerseits von einem Antriebsrad 58 angetrieben wird. Das Antriebsrad 58 wird von dem Revolver 34 angetrieben über ein zentrisches Zahnrad und ein Ritzel, so dass die Bewegung der Andrückwalze 55 in exakter Übereinstimmung mit der Drehbewegung des Revolvers 34 erfolgt. Während der Bewegung einer Tasche 33 mit Packungsgruppe 54 in die Codierstellung befindet sich die Umfangsfläche der Andrückwalze 55 in einer zurückgezogenen Position. Aufgrund der Lage des exzentrischen Wellenzapfens 56 wird erreicht, dass in der Codierposition gemäß Fig. 5 die Andrück- und Ausrichtkraft auf die Packungsgruppe 54 übertragen wird.The pressure roller 55 is arranged or movable so that a pressure and alignment effect is given only during the phase of the coding. The pressure roller 55 is therefore designed here as an eccentric or mounted on an eccentrically arranged shaft journal 56. This is driven in rotation, by a drive belt or toothed belt 57, which in turn is driven by a drive wheel 58. The drive wheel 58 is driven by the turret 34 via a central gear and a pinion, so that the movement of the pressure roller 55 takes place in exact accordance with the rotational movement of the turret 34. During movement of a bag 33 with packing group 54 into the coding position, the peripheral surface of the pressure roller 55 is in a retracted position. Due to the position of the eccentric shaft journal 56 is achieved that in the Codierposition according to Fig. 5 the pressing and aligning force is transferred to the packing group 54.

Um die Packungen 10 einer Packungsgruppe 54 zusätzlich oder alternativ im Bereich weiterer freier Flächen auszurichten, nämlich im Bereich der Frontseiten 13, sind zu beiden Seiten der Taschen 33 ortsfeste Führungsschienen 59 positioniert, die auf die zugekehrten Frontseiten 13 der Packungsgruppe 54 im Sinne einer exakten Ausrichtung der gesamten Packungsgruppe 54 einwirken.In order to align the packs 10 of a pack group 54 additionally or alternatively in the area of further free surfaces, namely in the region of the front sides 13, fixed guide rails 59 are positioned on both sides of the pockets 33, which points to the facing front sides 13 of the pack group 54 in the sense of exact alignment the entire packing group 54 act.

Bei dem Ausführungsbeispiel gemäß Fig. 7 dient ebenfalls ein (Trocken-)Revolver 34 zum Transport der Packungen 10 bzw. von Packungsgruppen 54. Zur Durchführung der Codierung mit Hilfe eines Laser-Codierers 19 werden die Packungen 10 bzw. die Packungsgruppe 54 zeitweilig und teilweise aus der Position innerhalb der Tasche 33 herausbewegt in eine Codierstellung. In dieser sind die mit einer Bedruckung zu versehenden Flächen oder Teilflächen der Packungen 10 frei. Bei dem Ausführungsbeispiel der Fig. 7 sind die Packungen 10 so positioniert bzw. bewegbar, dass nach oben oder zur Seite gerichtete Seitenflächen 14 teilweise freiliegen und durch den Laser-Codierer beaufschlagt werden können. Dieser kann dabei, wie in Fig. 7 gezeigt, in einer Stellung vertikal oberhalb der zu beaufschlagenden Packungen positioniert sein. Die Anordnung gemäß Fig. 7 gilt aber gleichermaßen auch für eine horizontale Anordnung bzw. Wirkungsrichtung des Laser-Codierers 19.In the embodiment according to Fig. 7 Also serves a (dry) turret 34 for transporting the packs 10 and of pack groups 54. To carry out the coding using a laser encoder 19, the packs 10 and the pack group 54 temporarily and partially from the position within the pocket 33rd moved out into a coding position. In this, the surfaces or partial surfaces of the packs 10 to be provided with a print are free. In the embodiment of the Fig. 7 For example, the packages 10 are positioned so that side faces 14 facing up or to the side may be partially exposed and acted upon by the laser encoder. This can, as in Fig. 7 shown in be positioned vertically above the packages to be acted on a position. The arrangement according to Fig. 7 but equally applies to a horizontal arrangement or direction of action of the laser encoder 19.

Für die Bewegung der Packungen 10 bzw. Packungsgruppen 54 dient ein gabelförmiger Schieber 45, vorzugweise für jede Tasche 33. Der Schieber 45 weist zwei miteinander verbundene Schenkel 46. 47 auf, die in einem im Wesentlichen der Länge bzw. sonstigen Abmessung der Packung 10 entsprechenden Abstand voneinander angeordnet sind. Der Schieber 45 wird der Tasche 33 durch Bewegung in Radialrichtung und in achsparalleler Richtung so zugestellt, dass die Gruppe der Packungen 10 innerhalb der Tasche 33 im Bereich der innenseitigen und außenseitigen Flächen, nämlich der Stirnfläche 15 und Bodenfläche 16, durch die Schenkel 46, 47 erfasst werden. Durch radial gerichtete Bewegung werden dann die Packungen 10 aus der Tasche 33 heraus bewegt in die in Fig. 7 gezeigte Position. Nach Durchführung der Bedruckung werden die Packungen 10 durch entsprechend gegenläufige Bewegung des Schiebers 45 in die Tasche 33 zurück geführt.For the movement of the packs 10 or groups of packages 54 is a fork-shaped slide 45, preferably for each pocket 33. The slider 45 has two interconnected legs 46. 47, which correspond in a substantially the length or other dimension of the pack 10 Are spaced apart from each other. The slider 45 is the bag 33 delivered by movement in the radial direction and in the axis-parallel direction so that the group of packages 10 within the pocket 33 in the region of the inside and outside surfaces, namely the end face 15 and bottom surface 16, by the legs 46, 47th be recorded. By radially directed movement then the packages 10 are moved out of the pocket 33 in the in Fig. 7 shown position. After carrying out the printing, the packs 10 are guided by correspondingly opposite movement of the slider 45 in the pocket 33 back.

Das vorstehend geschilderte Prinzip wird gemäß Fig. 8 und Fig. 9 in besonderer Weise verwirklicht. Die zu codierenden Packungen 10 werden ganz oder teilweise so aus der Tasche 33 heraus bewegt, dass sie während der Bewegung nacheinander an einem Laser-Codierer vorbei bewegt werden, von dem in Fig. 9 ein (bewegbarer) Laserstrahl 48 schematisch dargestellt ist.The above-described principle is according to FIGS. 8 and 9 realized in a special way. The packs 10 to be coded are wholly or partially moved out of the pocket 33 so that they are successively moved past a laser encoder during the movement, of which in FIG Fig. 9 a (movable) laser beam 48 is shown schematically.

Als Förderorgan für die Packungen 10 ist ein Schieber 49 der betreffenden Tasche 33 zugeordnet, der einen gabelförmigen Kopf 50 aufweist. Zwei im Abstand voneinander angeordnete Schenkel 51, 52 erfassen die Packungen 10 bzw. die Gruppe im Bereich von in Radialrichtung des Revolvers 34 an beiden Seiten freiliegenden Packungsflächen, nämlich an der Frontseite 13 und der gegenüberliegenden Seite. Die Packungen 10 werden durch den Schieber 49 in achsparalleler Richtung seitwärts aus der Tasche 33 heraus bewegt. Dabei werden die insbesondere nach oben gerichteten Seitenflächen 14 durch die entsprechende Relativbewegung des Schiebers 49 nacheinander durch den Laser-Codierer 19 bzw. durch den Laserstrahl 48 beaufschlagt, so dass dieser eine Codierung 53 an der erwünschten Stelle der Packung 10 anbringen kann. Nach der Codierung aller Packungen 10 durch entsprechende Bewegung des Schiebers 49 kehrt dieser mit den Packungen 10 in die Ausgangsstellung (Fig. 8) zurück. Der Revolver 34 wird dann um eine Position weiter bewegt.As a conveying member for the packs 10, a slide 49 of the relevant pocket 33 is associated, which has a fork-shaped head 50. Two spaced apart legs 51, 52 engage the packs 10 and the group, respectively, in the area of packing surfaces exposed on both sides in the radial direction of the revolver 34, namely on the front side 13 and the opposite side. The packs 10 are moved laterally out of the pocket 33 by the slider 49 in an axis-parallel direction. The particular upward side surfaces 14 are acted upon by the corresponding relative movement of the slider 49 successively through the laser encoder 19 and the laser beam 48 so that it can attach a coding 53 at the desired location of the package 10. After the coding of all packs 10 by corresponding movement of the slide 49 this returns with the packs 10 in the starting position ( Fig. 8 ) back. The revolver 34 is then moved one position further.

Fig. 10 zeigt eine besondere Lösung für die Integration der Bedruckung bzw. Codierung von Packungen 10 in eine Verpackungsmaschine für die Herstellung von Packungen 10 des Typs Hinge-Lid. Die Verpackungsmaschine ist auf zweibahnige Betriebsweise ausgerichtet. Die von einem Faltrevolver 60 kommenden Packungen werden entlang einer etwa mittig innerhalb der Verpackurigsmaschine verlaufenden Packungsbahn 61 transportiert und einem ersten Trockenrevolver 62 bekannter Bauart zugeführt. Von diesem gelangen die Packungen über einen Packungsförderer 63 zum zweiten Trockenrevolver, nämlich zum Revolver 34. Die Packungen 10 werden durch den Packungsförderer 63 in achsparalleler Richtung, in einem randseitigen Bereich des Revolvers 34 gefördert und in derselben Richtung von einem Abförderer 64 abtransportiert. Fig. 10 shows a particular solution for integrating the printing or coding of packages 10 in a packaging machine for the production of packages Hinge-Lid-type. The packaging machine is designed for two-lane operation. The packages coming from a folding turret 60 are transported along a packing path 61 running approximately centrally within the packaging machine and fed to a first drying turret 62 of known type. From this, the packages pass via a packing conveyor 63 to the second drying turret, namely to the turret 34. The packages 10 are conveyed by the package conveyor 63 in an axis-parallel direction, in an edge region of the revolver 34 and transported away in the same direction by a discharge conveyor 64.

Von besonderer Bedeutung ist die Positonierung des Revolvers 34 in einer frontseitigen Längsebene der Verpackungsmaschine. Dadurch ist rückseitig Raum für die Anordnung des Laser-Codierers 19 gegeben. Dieser besteht üblicherweise aus einem langgestreckten Gehäuse, welches hier an der Rückseite des Revolvers 34 positioniert ist. Neben dem Laser-Codierer 19 befindet sich ein Steuergerät 65, welches die Eingabe der zu druckenden Codierung ermöglicht und über eine Steuerleitung 66 mit dem Laser-Codierer 19 verbunden ist. Auch das Steuergerät 65 befindet sich am Ende bzw. Rand der Verpackungsmaschine in einer funktionell günstigen Position.Of particular importance is the positioning of the revolver 34 in a front longitudinal plane of the packaging machine. As a result, space for the arrangement of the laser encoder 19 is provided on the back. This usually consists of an elongated housing, which is positioned here on the back of the revolver 34. In addition to the laser encoder 19 is a control unit 65, which allows the input of the encoding to be printed and is connected via a control line 66 to the laser encoder 19. The control unit 65 is located at the end or edge of the packaging machine in a functionally favorable position.
