Vorrichtung zum Aufschneiden von FolienrollenDevice for cutting film rolls

Beschre ibungDescription

Bei der Herstellung von Kunststoffolien durch Extrusion oder Kalandrierung wird die erzeugte Folie auf sogenannten Wickelkernen aufgewickelt, wobei je nach bestimmungsgemäßem Gebrauch mehr oder weniger umfangreiche Folienrollen erhalten werden.When plastic films are manufactured by extrusion or calendering, the film produced is wound onto so-called winding cores, whereby more or less extensive film rolls are obtained depending on the intended use.

Im Falle von zum Beispiel Produktionsumstellungen, Produktionsstörungen oder Störungen im AufwickelVorgang fallen Folienrollen mit zum Beispiel Farbübergängen, Dickenübergängen oder mit nicht beidseitig kantengleichen Aufwicklungen an. Da die Fehlrollen nicht an den Verbraucher gehen können, versucht man dieses Folienmaterial als Folienrohstoff wieder einzusetzen. Dazu ist es notwendig, die fehlerhaften Folienrollen in gut handhabbare Folienstücke zu schneiden, was durch einen Längsschnitt erreicht wird, der über die ganze Folienbreite und durch die aufgewickelte Folie hindurch bis zum Wickelkern geht.In the event of production changes, production disruptions or disruptions in the winding process, for example, film rolls with color transitions, thickness transitions or with winding edges that are not even on both sides are produced. Since the defective rolls cannot be sent to the consumer, attempts are made to reuse this film material as film raw material. To do this, it is necessary to cut the defective film rolls into easily manageable film pieces, which is achieved by a longitudinal cut that goes across the entire width of the film and through the wound film to the winding core.

Zum Aufschneiden von Folienrollen ist eine Vorrichtung bekannt, die aus einem der Folienbreite entsprechend langen Stahlbandmesser besteht, das mit seiner Schneidkante in die Folienrolle eingedrückt wird. Im Falle von umfangreichen Aufwicklungen sind hohe Drücke erforderlich, wobei das Messer zusätzlich nur relativ langsam immer weiter eingedrückt werden kann. Ein weiterer Nachteil liegt darin, daß die Länge des Bandmessers der längsten Folienrolle entsprechen muß, um jeweils einen vollständigenA device is known for cutting film rolls, which consists of a steel band knife that is long enough to match the width of the film and is pressed into the film roll with its cutting edge. In the case of large rolls, high pressures are required, and the knife can only be pushed in relatively slowly. A further disadvantage is that the length of the band knife must correspond to the longest film roll in order to cut a complete film roll.

Längsschnitt zu gewährleisten. Nun sind aber schon aus konstruktiven Gründen der Messerlänge Grenzen gesetzt; sie kann im allgemeinen höchstens 2 m betragen. Die bekannte Langsschneidvorrichtung läßt somit mehrfach zu wünschen übrig.To ensure a longitudinal cut, however, there are limits to the length of the blades for structural reasons; in general, it can be no more than 2 m. The known longitudinal cutting device therefore leaves a lot to be desired.

Es wurde nun eine Aufschneidvorrichtung für Folienrollen gefunden, die weitgehend unabhängig von der Länge und Dicke der Rollen arbeitet und ein schnelles Zerschneiden gewährleistet.A cutting device for film rolls has now been found that works largely independently of the length and thickness of the rolls and ensures quick cutting.

Die erfindungsgemäße Vorrichtung ist gekennzeichnet durch einen Stahlrahmen zur Aufnahme einer an einem innerhalb des Stahlrahmens hin und her bewegbaren Führungsschlitten befestigten Schneideinrichtung und durch eine Hebebühne zur Aufnahme und Zufuhr der aufzuschneidenden Folienrolle zur Schneideinrichtung, die im wesentlichen aus einem Messerkopf und dem daran befestigten Blattmesser zum Längsaufschneiden der kontinuierlich herangeführten Folienrolle besteht.The device according to the invention is characterized by a steel frame for receiving a cutting device attached to a guide carriage that can be moved back and forth within the steel frame and by a lifting platform for receiving and feeding the film roll to be cut to the cutting device, which essentially consists of a knife head and the blade knife attached to it for longitudinally cutting the continuously fed film roll.

Das Blattmesser ist vorzugsweise federnd in der Schneideinrichtung fixiert und die Schneidkante des Blattmessers ist vorzugsweise konusförmig ausgebildet. Es ist ferner bevorzugt, daß die beiden Seitenkanten des Blattmessers mit einer schneidend ausgebildeten Einkerbung versehen sind, wodurch ein noch störungsfreieres Aufschneiden auch von nicht bündig gewickelten Folienrollen erreicht wird. Zum besseren Einführen des Folienrandes in die Einkerbung ist erfindungsgemäß eine Anschlageinrichtung vorgesehen, wodurch ein Ausweichen der Folien und damit ihr Hineinführen in die Einkerbung gewährleistet ist. Um ein schnelleres Auseinanderfallen der Folienblätter nach jedem Längsschnitt zu erreichen, sind erfindungsgemäß an beiden Seiten des Blattmessers Düsen vorgesehen, durch die Preßluft in den Bereich des Längsschnittes geblasen wird.The blade is preferably spring-mounted in the cutting device and the cutting edge of the blade is preferably conical. It is also preferred that the two side edges of the blade are provided with a cutting notch, which allows even smoother cutting of film rolls that are not wound flush. To better guide the edge of the film into the notch, a stop device is provided according to the invention, which ensures that the films move away and are therefore guided into the notch. In order to achieve faster disintegration of the film sheets after each longitudinal cut, nozzles are provided on both sides of the blade, through which compressed air is blown into the area of the longitudinal cut.

Die erfindungsgemäße Aufschneidvorrichtung wird anhand einer Zeichnung noch näher erläutert.The slicing device according to the invention is explained in more detail using a drawing.

Figur 1 zeigt eine bevorzugte Ausführungsform in perspektivischer Ansicht.Figure 1 shows a preferred embodiment in perspective view.

Figur 2 zeigt die Schneideinrichtung von Figur 1 im Detail in Vorderansicht.Figure 2 shows the cutting device of Figure 1 in detail in front view.

An dem in Figur 1 dargestellten Stahlrahmen 1 ist der Führungsschlitten 2, zum Beispiel mit Hilfe eines elektrischen Antriebsystems, hin und her bewegbar angeordnet. Am Führungsschlitten 2 ist die Schneideinrichtung aus dem Messerkopf 3 und dem Schneidmesser 4 befestigt. Die aufzuschneidende Folienrolle 6 wird mit Hilfe der Hebebühne 5 herangebracht.The guide carriage 2 is arranged on the steel frame 1 shown in Figure 1 so that it can move back and forth, for example with the help of an electric drive system. The cutting device consisting of the knife head 3 and the cutting knife 4 is attached to the guide carriage 2. The film roll 6 to be cut is brought in with the help of the lifting platform 5.

Wie aus Figur 2 hervorgeht, umfaßt die Schneideinrichtung den Messerkopf 3 und das in Form eines Blattmessers ausgebildete Schneidmesser 4 mit den ebenfalls schneidend ausgestalteten Einkerbungen 7. Das Blattmesser mit der konusförmigen Schneidkante 8 ist über den Messerkopf 3 mittels der Feder 9 federnd ausgestaltet. Der Schneideinrichtung 3, 4 sind die Luftdüsen 10 und die Anschlageinrichtung 11 zugeordnet.As can be seen from Figure 2, the cutting device comprises the knife head 3 and the cutting knife 4, which is designed in the form of a blade knife with the notches 7 that are also designed to cut. The blade knife with the conical cutting edge 8 is designed to be spring-loaded over the knife head 3 by means of the spring 9. The air nozzles 10 and the stop device 11 are assigned to the cutting device 3, 4.
