Derartige Vorrichtungen sind bekannterweise Bestandteile von Splicevorrichtungen, die bei Abwickelvorrichtungen für Wickelrollen aus Papier- oder Kartonbahnen das Ende der auslaufenden Materialbahn mit dem Bahnanfang einer neuen Wickelrolle verbinden. Sie dienen dazu, das Ende der ablaufenden Bahn und/oder den Anfang der neuen Bahn abzuschneiden, damit eine Verbindung der beiden Bahnen ohne oder mit nur geringer Überlappung hergestellt werden kann.Such devices are known to be components of splicing devices that in the case of unwinding devices for winding rolls made of paper or cardboard webs, the end of the Connect the outgoing material web to the start of the web of a new winding roll. she serve the end of the running path and / or the beginning of the new path cut off, so that a connection of the two webs with little or no Overlap can be made.

Zum Durchtrennen von Papier- oder Kartonbahnen von sehr großer Breite von 8 m und mehr ist aus der DE 199 23 097 A eine Vorrichtung der gattungsgemäßen Art bekannt. Sie enthält als Schneidelement ein Kreismesser, das drehbar an einem Wagen gelagert ist, der quer über die Bahnbreite mittels einer Linearantriebseinheit als Fahrantrieb verfahrbar ist. Das Kreismesser wird zum Schneiden gegen eine ebenfalls am Wagen befestigte Gegenrolle bewegt.For cutting paper or cardboard webs with a very large width of 8 m and DE 199 23 097 A discloses a device of the generic type. It contains a circular knife as a cutting element, which is rotatably mounted on a trolley is that across the web width by means of a linear drive unit as a travel drive is movable. The circular knife is also used to cut against one on the cart attached counter roller moves.

Frei drehbar gelagerte Kreismesser, die beim Durchtrennen der Bahn nur durch die Reibung mit der Bahn gedreht werden, sind bei bestimmten Papier- oder Kartonsorten nicht in der Lage, die Bahn sicher durchzutrennen. Insbesondere zu Beginn des Schneidvorgangs, wenn das Kreismesser am Bahnrand in die Bahn eintaucht, können bei frei drehbar gelagerten Kreismessern Probleme beim Schnitt auftreten. Circular knives freely rotatably mounted, which when cutting the web only through the Friction with the web are rotated with certain types of paper or cardboard unable to sever the web safely. Especially at the beginning of the Cutting process, when the circular knife dips into the path at the edge of the path, at freely rotating circular knives Problems with the cut occur.

Der Erfindung liegt die Aufgabe zugrunde, eine Trennvorrichtung der gattungsgemäßen Art so zu verbessern, daß ohne großen konstruktiven Aufwand ein sicheres Durchschneiden der Bahn auch an den Bahnrändern gewährleistet ist.The invention has for its object a separation device of the generic type Art to improve so that a safe cut through without great design effort the web is also guaranteed at the edges of the web.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß

  • über die Länge der Schneidstrecke ein Seil gespannt ist,
  • an dem Transportschlitten eine Seilscheibe frei drehbar gelagert ist,
  • das Seil in einer Umschlingung von 360° um die Seilscheibe geführt ist und,
  • die Seilscheibe mit dem Kreismesser Drehmomente übertragend gekuppelt ist.
This object is achieved according to the invention in that
  • a rope is stretched over the length of the cutting section,
  • a rope pulley is freely rotatably mounted on the transport carriage,
  • the rope is wrapped in a 360 ° loop around the sheave and,
  • the rope pulley is coupled with the circular knife transmitting torque.

Das Kreismesser weist so einen die Schnittqualität verbessernden Drehantrieb auf, der von dem Fahrantrieb des Transportschlittens angetrieben wird. Ein eigener, unabhängiger Drehantrieb mit Energiezufuhr ist nicht erforderlich.The circular knife thus has a rotary drive which improves the cut quality is driven by the travel drive of the transport carriage. A separate, independent one Rotary drive with energy supply is not required.

Die Trennvorrichtung nach dem Ausführungsbeispiel ist Bestandteil einer Splicevorrichtung zum Verbinden von sehr breiten (8 m und mehr) Papier- oder Kartonbahnen, wie sie in der DE 199 23 097-A beschrieben ist. Sie dient zum Durchtrennen der Bahn 1 quer zu deren Laufrichtung. Ebenso ist die Trennvorrichtung zum Durchtrennen schmalerer Bahnen einsetzbar. Als Schneidelement enthält die Trennvorrichtung ein Kreismesser 2, das an einem Transportschlitten 3 frei drehbar gelagert ist. Wie in Figur 3 dargestellt, ist der Transportschlitten 3 mit dem daran gelagerten Messer 2 mittels eines Fahrantriebs in beide Richtungen quer zur Bahnlaufrichtung über die Schneidstrecke linear verfahrbar. The separating device according to the exemplary embodiment is part of a splicing device for connecting very wide (8 m and more) paper or cardboard webs, like them is described in DE 199 23 097-A. It is used to cut the web 1 across their direction of travel. The separating device for cutting through is also narrower Lanes can be used. The cutting device contains a circular knife 2 as the cutting element, which is freely rotatably mounted on a transport carriage 3. As shown in Figure 3, is the transport carriage 3 with the knife 2 mounted thereon by means of a travel drive in both directions can be moved linearly across the cutting path transverse to the web running direction.

Da die gesamte Bahn 1 über ihre Breite durchgetrennt werden soll, entspricht die Schneidstrecke der Bahnbreite.Since the entire web 1 is to be cut across its width, this corresponds to Cutting distance of the web width.

Als Fahrantrieb für den Transportschlitten 3 wird nach dem Ausführungsbeispiel ein zwischen Umlenkrollen 4 gespanntes umlaufendes Band 5 verwendet, an das der in einer Führung laufende Transportschlitten 3 festgeklemmt ist. Eine der Umlenkrollen 4 ist mit einem Drehantrieb verbunden, der das Band 5 mit dem daran befestigten Transportschlitten 3 in beide Richtungen quer zur Bahn 1 bewegt. Anstelle eines angetriebenen Bandes 5 können auch andere Linearantriebe verwendet werden, beispielsweise eine Linearantriebseinheit, deren Mitnehmer mit dem Transportschlitten 3 verbunden ist oder ein sich über die Schneidstrecke erstreckender kolbenstangenloser Zylinder.According to the embodiment, a is used as the drive for the transport carriage 3 between the deflection rollers 4 tensioned circulating belt 5 to which the in a Guide running transport carriage 3 is clamped. One of the pulleys 4 is with a rotary drive connected to the belt 5 with the transport carriage attached to it 3 moved in both directions across the web 1. Instead of a powered one Band 5 can also be used other linear drives, for example one Linear drive unit, whose driver is connected to the transport carriage 3 or a rodless cylinder extending over the cutting distance.

Parallel zur Schneidstrecke, also zur Fahrstrecke des Transportschlittens 3, und mit geringem Abstand unterhalb der Ebene der Bahn 1 ist quer über die Arbeitsbreite ein Seil 6 gespannt. Das Seil 6 ist mit seinen Enden jeweils an einer Maschinenseite an dem Gehäuse 7 der Splicevorrichtung befestigt. Bevorzugt ist das Seil 6 in Längsrichtung elastisch verformbar oder federnd gelagert, damit es geradlinig gespannt verläuft. Im vorliegenden Ausführungsbeispiel wird ein Seil 6 aus Polyamid (Nylon) von 0,5 - 1 mm Durchmesser verwendet, das an einem Ende über eine Zugfeder 8 an dem Gehäuse 7 befestigt ist. Mittels der Zugfeder 8 läßt sich die Spannung des Seils 6 einstellen.Parallel to the cutting section, that is to the travel section of the transport carriage 3, and with A short distance below the level of the web 1 is a rope across the working width 6 excited. The ends of the rope 6 are on one machine side at the Housing 7 of the splicer attached. The rope 6 is preferably in the longitudinal direction elastically deformable or spring-loaded so that it runs in a straight line under tension. in the The present exemplary embodiment uses a rope 6 made of polyamide (nylon) of 0.5-1 mm Diameter used at one end via a tension spring 8 on the housing 7 is attached. The tension of the cable 6 can be adjusted by means of the tension spring 8.

Das Seil 6 ist in einer Umschlingung von 360° um eine Seilscheibe 9 geführt, die am Schlitten 3 frei drehbar gelagert ist. Eine Linearbewegung des Transportschlittens 3 führt somit zu einer Drehbewegung der Seilscheibe 6. Um eine seitliche Verschiebung und ein Abspringen des Seiles 6 von der Seilscheibe 9 zu verhindern, ist das Seil 6 in einer umlaufenden Umfangsnut 10 der Seilscheibe 6 geführt.The rope 6 is guided in a wrap of 360 ° around a pulley 9, which on Carriage 3 is freely rotatable. A linear movement of the transport carriage 3 leads thus to a rotational movement of the sheave 6. By a lateral displacement and a To prevent the rope 6 from jumping off the sheave 9, the rope 6 is in one circumferential circumferential groove 10 of the pulley 6 out.

Um die Drehbewegung der Seilscheibe 6 auf das Kreismesser 2 zu übertragen, ist die Seilscheibe 6 mit dem Kreismesser 2 Drehmomente übertragend gekuppelt. Bevorzugt ist das Kreismesser 2 außen koaxial an der Seilscheibe 9 befestigt und weist einen etwas größeren Außendurchmesser als diese auf, so daß die Schneidkante des Kreismessers 2 radial übersteht. Im vorliegenden Ausführungsbeispiel hat das Kreismesser 2 einen Außendurchmesser von ca. 60 mm, die Seilscheibe 9 einen Außendurchmesser von ca. 50 mm. Die Seilscheibe 6 ist bevorzugt über Kugellager 11 auf einem Achszapfen 12 gelagert, der an den Transportschlitten 3 befestigt ist. Zum Schneiden wird das an der Seilscheibe 6 befestigte Kreismesser 2 gegen eine Gegenrolle 13 bewegt, die ebenfalls an dem Transportschlitten 3 frei drehbar gelagert ist.In order to transmit the rotary movement of the rope pulley 6 to the circular knife 2, the Pulley 6 coupled with the circular knife transmitting 2 torques. Is preferred the circular knife 2 coaxially attached to the outside of the rope pulley 9 and has a little larger outer diameter than this, so that the cutting edge of the circular knife 2nd protrudes radially. In the present exemplary embodiment, the circular knife 2 has one Outer diameter of approx. 60 mm, the pulley 9 has an outer diameter of approx. 50 mm. The pulley 6 is preferably on a journal 12 via ball bearings 11 stored, which is attached to the transport carriage 3. To cut it on the Cable pulley 6 attached circular knife 2 moves against a counter roller 13, which also is freely rotatably mounted on the transport carriage 3.

Bei der linearen Bewegung des Transportschlittens 3 mittels seines Fahrantriebs wird somit über das Seil 6 zwangsweise eine Rotation des Kreismessers 2 erzeugt. Der Fahrantrieb des Transportschlittens 3 wirkt somit zugleich als Drehantrieb für das Kreismesser 2, der gleichzeitig mit der Bewegung des Transportschlittens 3 aktiviert wird. Wird der Transportschlitten 3 außerhalb der Bahnbreite gestartet, so wirkt der Drehantrieb des Kreismessers 2 bereits beim Eintauchen des Kreismessers 2 in die Bahn 1 an deren Rand und gewährleistet so ein sicheres Anschneiden der Bahn 1.During the linear movement of the transport carriage 3 by means of its travel drive thus a rotation of the circular knife 2 is forcibly generated via the cable 6. The Travel drive of the transport carriage 3 thus also acts as a rotary drive for the Circular knife 2, which is activated simultaneously with the movement of the transport carriage 3. If the transport carriage 3 is started outside the web width, the rotary drive acts of the circular knife 2 already when the circular knife 2 is immersed in the web 1 the edge and thus ensures a safe cutting of the web 1.
