Description

Die Erfindung betrifft eine Vorrichtung zum Anbringen von Prägungen an Zuschnitten aus (dünnem) Karton oder ähnlichem Verpackungsmaterial für die Fertigung von Zigarettenpackungen, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a device for applying embossings to blanks made of (thin) cardboard or similar packaging material for the manufacture of cigarette packets, according to the preamble of claim 1.

Die Anbringung von Materialverformungen, nämlich Prägungen, im Bereich eines Kragens einer Zigarettenpackung des Typs Klappschachtel während des Abtrennens eines Kragen-Zuschnitts von einer Materialbahn aus dünnem Karton ist bekannt durch die WO 2006/012960 A1 . Bei dieser bekannten Vorrichtung werden Kragenzuschnitte im Bereich von Walzen von der Materialbahn abgetrennt. Eine der Walzen, nämlich eine Messerwalze, ist am Umfang mit konturierten Trennmessern bzw. Schneiden versehen. Die gegenüberliegende Walze, nämlich Gegenwalze, ist mit einer glatten Mantelfläche ausgebildet. An der Messerwalze sind benachbart zu den Schneidmessern Prägeorgane angebracht, die eine Verformung der Materialbahn bzw. des Kragenzuschnitts im Bereich zwischen den Walzen bewirken. Der Prägeeffekt ist jedoch unbefriedigend.The application of material deformations, namely embossing, in the region of a collar of a cigarette pack of the folding box type during the separation of a collar blank from a material web of thin cardboard is known from US Pat WO 2006/012960 A1 , In this known device collar blanks are separated in the range of rolls of the material web. One of the rolls, namely a knife roll, is provided on the circumference with contoured cutting knives or cutting edges. The opposite roller, namely counter-roller, is formed with a smooth lateral surface. On the knife roller adjacent to the cutting blades embossing elements are mounted, which cause a deformation of the material web or the collar blank in the area between the rollers. However, the embossing effect is unsatisfactory.

Weiterhin ist aus der EP 1 650 016 A1 bekannt Materialbahnen vollflächig beiderseits zu Prägen. Hierzu ist die jeweilige Mantelfläche von zwei Prägewalzen, die zusammen von jeweils einer Seite auf die Materialbahn einwirken, mit korrespondieren Vorsprüngen versehen, die die Materialbahn in Art einer Patrize und Matrize prägen.Furthermore, from the EP 1 650 016 A1 known material webs over the entire surface on both sides to embossing. For this purpose, the respective lateral surface of two embossing rollers, which act together from one side to the material web, provided with corresponding projections which emboss the web in the manner of a male and female.

Der Erfindung liegt die Aufgabe zugrunde, die eingangs genannte Vorrichtung so weiter zu entwickeln, dass optimale Prägungen in den Zuschnitten bzw. in der Materialbahn aus dünnem Karton oder ähnlichem Werkstoff, insbesondere im Bereich eines Kragenzuschnitts, hergestellt werden können.The invention has for its object to further develop the device mentioned above so that optimal imprints in the blanks or in the web of thin cardboard or similar material, in particular in the range of Kragenzuschnitts, can be produced.

Zur Lösung dieser Aufgabe weist die erfindungsgemäße Vorrichtung die Merkmale des Anspruchs 1 auf.To solve this problem, the device according to the invention has the features of claim 1.

Die Besonderheit der Erfindung besteht demnach darin, dass der dünne Karton durch Prägeorgane im Sinne von Matrize und Patrize beaufschlagt wird. Dadurch ergibt sich auch bei sehr kurzen Arbeitstakten eine auffällige und dauerhafte Prägeverformung.The peculiarity of the invention is therefore that the thin cardboard is acted upon by embossing organs in the sense of female and male. This results in a conspicuous and permanent embossing deformation even with very short work cycles.

Insbesondere sind zusammenwirkende Prägebereiche bzw. Prägestücke an umlaufenden Walzen einer Messerwalzeneinheit zum Herstellen von Kragenzuschnitten angeordnet, wobei die Kragenzuschnitte für die Herstellung von Zigarettenpackungen des Typs Klappschachtel eingesetzt werden. Die wirksame Prägung wird mit der Anbringung eines Trennschnitts für den Zuschnitt kombiniert.In particular, cooperating embossing areas or embossing pieces are arranged on revolving rolls of a knife roller unit for producing collar pieces, wherein the collar pieces are used for the production of cigarette packs of the folding box type. The effective embossing is combined with the application of a cutting cut for the blank.

Die Prägestücke sind lösbar in Ausnehmungen der Walzen angeordnet, nämlich in der Messerwalze einerseits und alternativ auch der Gegenwalze andererseits, sodass diese während des Prägevorgangs zu beiden Seiten des Zuschnitts bzw. der Materialbahn liegen und aufgrund der formgebenden Druckübertragung die Prägung erzeugen. Vorsprünge des einen Prägestücks sind dabei im Bereich von korrespondierenden Vertiefungen des anderen Prägestücks wirksam. Mindestens eines der Prägestücke ist verstellbar angeordnet zur Veränderung der Relativstellung, insbesondere im Zusammenhang mit der Abmessung der am Umfang de Messerwalze angeordneten Messerschneiden.The embossing pieces are detachably arranged in recesses of the rolls, namely in the knife roll on the one hand and alternatively also the counter roll on the other hand, so that they lie during the embossing process on both sides of the blank or the material web and produce the embossing due to the shaping pressure transfer. Projections of one embossing piece are effective in the region of corresponding recesses of the other embossing piece. At least one of the embossing pieces is adjustably arranged to change the relative position, in particular in connection with the dimension of the circumference de knife roller arranged knife edges.

Alternativ können korrespondierende Prägebereiche in der Mantelfläche der Gegenwalze eingearbeitet bzw. eingeformt sein. Hierbei ist vorteilhaft, dass die Gegenwalze einen Mantel aus besonders hartem Werkstoff aufweist. nämlich einen Mantel aus Keramik oder Sintermetall. In den Mantel der betreffenden Walze, insbesondere in den aus hartem Werkstoff bestehenden Mantel, sind Prägebereiche mit Vorsprüngen und Vertiefungen eingearbeitet, insbesondere in der Funktion als Matrize.Alternatively, corresponding stamping areas can be incorporated or formed in the mantle surface of the mating roll. It is advantageous that the counter-roller has a jacket made of particularly hard material. namely a jacket made of ceramic or sintered metal. In the shell of the respective roller, in particular in the coat of hard material, embossing areas are incorporated with projections and recesses, in particular in the function of a die.

In den Zeichnungen ist das bevorzugte Anwendungsgebiet dargestellt, nämlich die Anbringung von Prägungen 10 an einer Zigarettenpackung aus dünnem Karton, hier in der Ausführung als Klappschachtel bzw. Hinge Lid Pack. Dieser Packungstyp besteht standardmäßig aus einem (unteren) Schachtelteil 11, einem mit diesem schwenkbar verbundenen Deckel 12 und einem hier aus einem gesonderten Zuschnitt bestehenden Kragen 13. Dieser bildet eine Kragen-Vorderwand 14 und Kragen-Seitenlappen 15. Der Kragen 13 ist im Schachtelteil 11 angeordnet und innenseitig mindestens mit einer Schachtel-Vorderwand 16 verbunden. Ein oberer Teilbereich ragt aus dem Schachtelteil 11 heraus und ist bei offenem Deckel 12 sichtbar. Innerhalb der so ausgebildeten Klappschachtel ist ein quaderförmiger Zigarettenblock 17 als Packungsinhalt angeordnet.In the drawings, the preferred application is shown, namely the attachment of embossments 10 on a cigarette pack made of thin cardboard, here in the execution as a folding box or Hinge Lid Pack. By default, this type of packing consists of a (lower) box part 11, a cover 12 pivotally connected thereto and a collar 13 here of a separate blank. This forms a collar front wall 14 and collar side tabs 15. The collar 13 is in the box part 11 arranged and connected on the inside at least with a box front wall 16. An upper portion protrudes from the box part 11 and is visible with the lid 12 open. Within the folding box thus formed a cuboid cigarette block 17 is arranged as a package contents.

Die Prägung 10 ist bei der Zigarettenpackung bzw. Klappschachtel mit vorstehendem Aufbau am Kragen 13 angebracht, und zwar an der Kragen-Vorderwand 14 in einem aus dem Schachtelteil 11 herausragenden Bereich. Die Prägung 10 ist hier als dekoratives Element ausgebildet. Es können aber alternativ oder zusätzlich Prägungen mit Informationen, also Schriftzeichen oder Symbole mit kennzeichnendem Charakter angebracht werden.The embossment 10 is attached to the cigarette pack or folding box with the above structure on the collar 13, on the collar front wall 14 in a protruding from the box part 11 area. The embossment 10 is formed here as a decorative element. However, as an alternative or in addition, embossing with information, that is to say characters or symbols with a characterizing character, can be applied.

Die Prägung 10 wird in besonderer Weise hergestellt, nämlich mit einer Materialverformung, die aus der Ebene des Materials des Prägungsträgers einseitig oder beidseitig heraustritt. Bei dem vorliegenden Ausführungsbeispiel (Fig. 6, Fig. 8) ist die Prägung so ausgebildet, dass sie einseitig, nämlich zur freien Sichtseite des Kragens 13, über die Ebene des Zuschnitts bzw. der Kragen-Vorderwand 14 hinweg ragt.The embossment 10 is produced in a special way, namely with a material deformation that emerges from the plane of the material of the embossing carrier on one side or on both sides. In the present embodiment ( Fig. 6 . Fig. 8 ), the embossing is designed so that it protrudes on one side, namely the free visible side of the collar 13, over the plane of the blank or the collar front wall 14 of time.

Die Prägung 10 wird im Bereich eines kontinuierlich arbeitenden Prägeaggregats angebracht mit drehenden Prägewalzen, zwischen denen der zu prägende Zuschnitt oder eine Materialbahn 18 aus (dünnem) Karton hindurch bewegt wird. Zum Anbringen der Prägung 10 an einem Kragen 13 wird ein Kragenapparat (Fig. 3) eingesetzt mit zu beiden Seiten der Materialbahn 18, insbesondere oberhalb und unterhalb, angeordneten Walzen. Es handelt sich dabei um eine (obere) Messerwalze 19 und eine (untere) Gegenwalze 20. Die Materialbahn 18 wird zwischen den beiden Walzen 19, 20 (kontinuierlich) hindurch gefördert, wobei positionsgenau die Prägung 10 angebracht und etwa zeitgleich ein Zuschnitt für den Kragen 13 abgetrenntwird. Die Materialbahn 18 wird durch ein Antriebsorgan gefördert, hier durch Vorschubwalzen 21, 22. MitAbstand vor den Walzen 19, 20 ist ein Organ zum Erfassen von Markierungen an der Materialbahn angeordnet, nämlich ein Sensor 23, der Druckmarken an der Materialbahn 18 abtastet und so die Walzen 19, 20 steuert.The embossment 10 is mounted in the region of a continuously operating embossing unit with rotating embossing rollers, between which the blank to be embossed or a material web 18 of (thin) cardboard is moved through. For attaching the embossment 10 on a collar 13 is a collar apparatus ( Fig. 3 ) used with on both sides of the material web 18, in particular above and below, arranged rollers. This is an (upper) knife roller 19 and a (lower) counter roller 20. The material web 18 is conveyed between the two rollers 19, 20 (continuously) through, wherein the exact position of the embossing 10 attached and about the same time a blank for the collar 13 is separated. The material web 18 is conveyed by a drive member, here by feed rollers 21, 22. With distance in front of the rollers 19, 20 an organ for detecting markings on the material web is arranged, namely a sensor 23 which scans printed marks on the material web 18 and so on Rolls 19, 20 controls.

Am Umfang, nämlich an der Mantelfläche der Walzen 19, 20 sind Prägebereiche angebracht, bei dem Ausführungsbeispiel gemäß Fig. 3 bis Fig. 9 Prägestücke 24, 25.
