Weitere Ausgestaltungen der Erfindung sind der nachfolgenden Beschreibung und den Unteransprüchen zu entnehmen.Further refinements of the invention can be found in the following description and the subclaims.
Die Erfindung wird nachstehend anhand des in den beigefügten Abbildungen dargestellten Ausführungsbeispiels näher erläutert.The invention is explained below with reference to the embodiment shown in the accompanying figures.
Fig. 1 zeigt schematisiert eine Seitenansicht einer Vorrichtung zum Herstellen von Zargen, die einer Verpackungsstation für Zigaretten zugeführt werden.1 schematically shows a side view of a device for producing frames which are fed to a packaging station for cigarettes.
Fig. 2 zeigt eine Frontansicht eines Teils der Vorrichtung von Fig. 1.FIG. 2 shows a front view of part of the device of FIG. 1.
Fig. 3 zeigt eine Draufsicht auf den in Fig. 2 dargestellten Teil der Vorrichtung.Fig. 3 shows a plan view of the part of the device shown in Fig. 2.
Fig. 4 zeigt in Draufsicht eine Zarge für ein Zigaretten-Klappdeckelpäckchen.Fig. 4 shows a top view of a frame for a cigarette folding lid packet.
Bei der dargestellten Vorrichtung befinden sich Verpackungsmaterialbahnen 1 auf nicht dargestellten Bobinen, wobei eine der Verpackungsmaterialbahnen 1 kontinuierlich über Rollen 2 einer Bahnwechseleinrichtung 3 zugeführt, durch diese hindurch transportiert, von weiteren Rollen 4 einer ein Paar von zusammenarbeitenden Messerwalzen 5 aufweisenden Zargenschneidstation zugeführt, von den Messerwalzen 5 in Zargen zerschnitten und als solche einer Verpackungsstation zugeführt wird. Führungen 6 dienen zum Führen der Verpakkungsmaterialbahnen 1 bzw. der Zargen zwischen den Rollen 2, 4 bzw. Walzen 5.In the device shown, packaging material webs 1 are located on bobbins (not shown), one of the packaging material webs 1 being fed continuously via
Die Bahnwechseleinrichtung 3 umfaßt ein feststehendes Messer 7 mit zwei einander gegenüberliegenden Schneidkanten 8. Jede der beiden Schneidkanten 8 dient jeweils zum Durchtrennen einer der beiden Verpackungsmaterialbahnen 1 entsprechend dem Verlauf einer Zarge an deren Vorder- bzw. Hinterkante, vgl. Fig. 4. Das Messer 7 ist innerhalb des durch die beiden im Spalte zwischen den Rollen 4 zusammen laufenden Transportwege der beiden Verpackungsmaterialbahnen 1 gebildeten spitzen Winkel angeordnet, wobei jeweils eine Schneidkante 8 einer Verpackungsmaterialbahn 1 zugewandt ist, und mit einem sich in Richtung auf die Rollen 4 erstreckenden und verjüngenden Führungsstück 9 versehen. Auf denen dem feststehenden Messer 7 abgewandten Seiten der beiden Transportwege für die Verpackungsmaterialbahnen 1 befindet sich jeweils ein bewegliches Messer 10. Die Messer 10 sind jeweils über einen Kolben 11 eines Druckluftzylinders 12 in Schneidstellung zum feststehenden Messer 7 bringbar.The
Ferner umfaßt die Bahnwechseleinrichtung 3 zwei verstellbare Führungsleisten 13 zum Überbrücken des Weges zwischen dem jeweiligen äußeren beweglichen Messer 10 und einer in Transportrichtung nachfolgenden feststehenden Führung 6. Jede Führungsleiste 13 ist beispielsweise über eine manuell betätigbare Kurbel 14 derart verstellbar, daß sie die in Fig. 1 gestrichelte Position einnimmt, in der sie den Weg für die Verpackungsmaterialbahn 1 zu den Messerwalzen 5 blockiert und die Verpackungsmaterialbahn 1 in einen Entnahmeschlitz 15 lenkt. Normalerweise ist die Kurbel 14 mittels eines am Rahmen 16 einrastenden Zapfens 17 in der den Weitertransport zu den Messerwalzen 5 zulassenden Stellung für die Führungsleiste 13 blockiert.Furthermore, the
Eine Verpackungsmaterialbahn 1 wird durch die Bahnwechselstation 3 hindurch eingefädelt, bis sie aus dem entsprechenden Entnahmeschlitz 15 herausragt. Die Betätigung des zugehörigen Messers 10 wird über das Auslösen der Betätigung des zugehörigen Zylinders 12 bewirkt, wodurch das vordere Ende der Verpackungsmaterialbahn 1 abgetrennt wird und manuell entnommen werden kann, während die verbleibende Verpackungsmaterialbahn 1 jetzt eine Vorderkante mit einer der Vorderkante der späteren Zarge entsprechenden Form aufweist. Nun erfolgt ein maschinengesteuerter Vorzug der Verpackungsmaterialbahn 1 derart, daß die Vorderkante die Messer der Messerwalzen 5 der nachfolgenden Zargenschneidstation gerade nicht berührt. Beim anschließenden Fördern werden jeweils Zargen vorbestimmter Länge abgetrennt, die der nachfolgenden Verpakkungsstation zugeführt werden. Lediglich die erste Zarge ist geringfügig kürzer, damit die Messerwalzen 5 beim ersten Mal ins Leere schneiden und kein schmaler Streifen abgetrennt wird, der zu Störungen führen könnte.A packaging material web 1 is threaded through the
Die zweite Verpackungsmaterialbahn 1 wird ebenfalls durch die Bahnwechseleinrichtung 3 eingefädelt und zugeschnitten, bleibt dann jedoch in dieser Stellung, bis die erste Verpackungsmaterialbahn 1 praktisch verbraucht ist. Wird über einen entsprechenden Sensor gemeldet, daß das Ende der ersten Verpackungsmaterialbahn 1 nahezu erreicht ist, wird die Maschinendrehzahl auf eine vorbestimmte Solldrehzahl verringert. Nach deren Erreichen wird das Messer 10 für die erste Verpackungsmaterialbahn 1 über eine elektronische Steuerung betätigt, wodurch die erste Verpackungsmaterialbahn 1 eine der Hinterkante einer Zarge entsprechende Hinterkante am Ende erhält. Der Vorzug für die erste Verpackungsmaterialbahn 1 vor der Bahnwechseleinrichtung 3 wird unterbrochen und der entsprechende Vorzug für die zweite Verpackungsmaterialbahn 1 zugeschaltet. Nun laufen das geformten Ende der ersten und der geformte Anfang der zweiten Verpackungsmaterialbahn 1 mit einer kleinen Lücke zueinander in die Zargenschneidstation. Die Maschinendrehzahl wird wieder entsprechend erhöht und am Ende der zweiten Verpackungsmaterialbahn 1 der Wechselvorgang wiederholt.The second packaging material web 1 is also through the
Der Abstand zwischen den Schneidkanten der Messer 7, 10 und denen der Messer der Zargenschneidstation beträgt zweckmäßigerweise ein Vielfaches der Zargenlänge in Förderrichtung plus ein geringes Spiel von beispielsweise 1 mm, um das Erzeugen von Schnippsel in der Zargenschneidstation bei Vorschubumschaltung ohne Zeitverzögerung zu unterbinden.The distance between the cutting edges of the
Wie sich aus Fig. 2 und 3 ergibt, können die beweglichen Messer 10 Führungsbuchsen 18 aufweisen, die Führungsstangen 19 aufnehmen, die ihrerseits ortsfest in Rahmenteilen 20 angeordnet sind, um die beweglichen Messer 10 in senkrechter Richtung zum feststehenden Messer 7 zu führen. Die Rahmenteile 20 tragen auch die Zylinder 12. Außerdem sind zwischen den beweglichen Messern 10 Federn 21 angeordnet, die die Messer 10 gegen die Beaufschlagungsrichtung der Zylinder 12 auswärts vorspannen. Die Federn 21 werden von Stangen 22 gestützt, die an den Rahmenteilen 20 befestigt sind.As can be seen from FIGS. 2 and 3, the
