Die Erfindung betrifft ein Verfahren zum Durchtrennen einer laufenden Materialbahn, insbesondere einer Papierbahn, bei dem die Materialbahn nacheinander auf mehrere Wickelkerne, insbesondere Tamboure, aufge wickelt und jeweils mit dem Aufwickeln auf einen neuen Wickelkern be gonnen wird, wenn eine auf einem vorherigen alten Wickelkern gebildete Wickelrolle einen vorbestimmten Durchmesser erreicht hat, wobei der neue Wickelkern zwischen eine Wickelwalze, insbesondere eine Tragwalze, und den alten Wickelkern, dem die Materialbahn über die Wickelwalze zu geführt wird, gebracht und die laufende Materialbahn in dem Bereich zwi schen einem Spalt, der von der Wickelwalze und dem neuen Wickelkern gebildet wird, und der auf dem alten Wickelkern gebildeten Wickelrolle durchtrennt wird.The invention relates to a method for cutting a running Material web, in particular a paper web, in which the material web successively on several winding cores, in particular drum winds and each with winding on a new winding core is won if one formed on a previous old winding core Has reached a predetermined diameter, the new winding core between a winding roller, in particular a support roller, and the old winding core, to which the material web passes over the winding roller is performed, brought and the running material web in the area between gap between the winding roller and the new winding core is formed, and the winding roll formed on the old winding core is severed.
Die Erfindung betrifft außerdem eine Vorrichtung zur Durchführung eines derartigen Verfahrens mit wenigstens einer Schneidvorrichtung.The invention also relates to a device for carrying out a such method with at least one cutting device.
Derartige Trennverfahren und -vorrichtungen werden beispielsweise in der Papierherstellung angewendet, um die fertige Papierbahn ohne Unterbre chung des Herstellungsprozesses, d. h. ohne Abschalten der Papierma schine, nacheinander auf mehrere Wickelkerne, die auch als Tamboure bezeichnet werden, aufzuwickeln. Such separation methods and devices are for example in the Papermaking applied to the finished paper web without undersize the manufacturing process, d. H. without switching off the paper size shine, one after the other on several winding cores, which also act as reels be referred to wind up.
Dabei muß dafür gesorgt werden, daß der durch das Durchtrennen der Materialbahn entstehende neue Bahnanfang dem neuen Wickelkern zu geführt wird, um auf diesem eine neue Wickelrolle zu bilden.It must be ensured that the by cutting the The new start of the material is created by the material web is performed to form a new winding roll on this.
Aus der WO 97/48632, der US 5,360,179 sowie der EP 0 658 504 B1 ist es jeweils bekannt, die Papierbahn vor dem Wickelspalt zwischen der Wic kelwalze und dem neuen Wickelkern zu durchtrennen und dazu beispiels weise mit schräg zur Bahnlaufrichtung verlaufenden oder gekrümmten Schnittlinien zu versehen. Bei dem Durchtrennen der Papierbahn vor dem Wickelspalt besteht die Gefahr, daß der neue Bahnanfang zurückspringt und nicht in den Wickelspalt geführt werden kann.From WO 97/48632, US 5,360,179 and EP 0 658 504 B1 it is known that the paper web in front of the winding gap between the wic to cut the kelwalze and the new winding core and for example wise with or oblique to the web running direction To provide cutting lines. When cutting the paper web before Winding gap there is a risk that the new beginning of the web will spring back and cannot be fed into the winding gap.
Es ist des weiteren bekannt, mittels einer schwenkbaren maschinenbrei ten Trennvorrichtung zwischen dem neuen und dem alten Wickelkern, d. h. hinter dem Wickelspalt, in die Papierbahn zu schlagen. Die dabei ent stehende, senkrecht zur Bahnlaufrichtung verlaufende Schnittkante kann zu Problemen beim Aufwickeln des neuen Bahnanfangs auf dem neuen Wickelkern führen.It is also known by means of a swiveling machine pulp separating device between the new and the old winding core, d. H. behind the winding nip to punch in the paper web. The ent vertical cutting edge perpendicular to the web running direction problems with winding the new start of the web on the new one Guide the winding core.

Hierdurch kann in der Materialbahn eine Schnittlinie erzeugt werden, die schräg zur Laufrichtung der Materialbahn von einem Rand der Material bahn zu deren gegenüberliegendem Rand verläuft. Die dadurch erzeugte schräge Kante des neuen Bahnanfangs kann auch bei sehr hohen Bahn geschwindigkeiten vergleichsweise problemlos auf den neuen Wickelkern aufgewickelt werden. Hierbei entsteht ein konisch gewickelter Wickelan fang.As a result, a cutting line can be generated in the material web at an angle to the running direction of the material web from an edge of the material path to the opposite edge. The generated by it The sloping edge of the new path start can also be used when the path is very high speeds comparatively easily on the new winding core be wound up. This creates a conically wound wrap catch.

Gleichzeitig oder im Anschluß daran wird mittels des Betätigungsorgans 34 der Träger 38 in die Trennstellung gemäß Fig. 1 geschwenkt, wobei sich das Messer 24 in der in Fig. 2 gestrichelt dargestellten Ruhestellung auf der von der Papierbahn 10 abgewandten Seite des Endlosorgans 40 befindet.Simultaneously or subsequently, the actuator 38 is pivoted into the separation position according to FIG. 1 by means of the actuating member 34 , the knife 24 being in the rest position shown in dashed lines in FIG. 2 on the side of the endless member 40 facing away from the paper web 10 .
Wenn der gewünschte Durchmesser der Wickelrolle 16 auf dem alten Wic kelkern 14 erreicht ist, wird das Endlosorgan 40 in Richtung eines Pfeils A in Bewegung gesetzt, wobei das Messer 24 aus seiner Ruhestellung heraus derart beschleunigt wird, daß es spätestens nach Umlaufen der in Fig. 2 linken Umlenkrolle 42 die gewünschte Geschwindigkeit erreicht hat. Die mit unverminderter Geschwindigkeit laufende Papierbahn 10 wird dann - beginnend an deren in Fig. 2 linkem Rand - durch das mit einer konstanten Geschwindigkeit, die bevorzugt 10 bis 40 m/s beträgt, laufen de Messer 24 vollständig durchgetrennt.When the desired diameter of the winding roll 16 on the old wic kelkern 14 is reached, the endless member 40 is set in the direction of an arrow A in motion, the knife 24 being accelerated out of its rest position in such a way that it rotates at the latest after revolving the in Fig. 2 left pulley 42 has reached the desired speed. The paper web 10 running at undiminished speed is then - starting at its left edge in FIG. 2 - completely cut through by the knife 24 running at a constant speed, which is preferably 10 to 40 m / s.
Durch die Überlagerung der Bewegungen der Papierbahn 10 und des Mes sers 24 entsteht eine schräg zur Bahnlaufrichtung B verlaufende Schnitt linie 46, wobei der Winkel, den die Schnittlinie 46 mit der Bahnlaufrich tung B einschließt, von dem Verhältnis der Geschwindigkeiten des Mes sers 24 und der Papierbahn 10 abhängt.The superimposition of the movements of the paper web 10 and the knife 24 creates an oblique to the web running direction B cutting line 46 , the angle which the cutting line 46 includes the web running direction B, from the ratio of the speeds of the knife 24 and the Paper web 10 depends.
Die an der führenden Kante 10b des neuen Bahnanfangs 10a somit schräg zur Bahnlaufrichtung B geschnittene Papierbahn 10 wird an schließend gegebenenfalls unter Zuhilfenahme geeigneter Mittel auf dem neuen Wickelkern 12 aufgewickelt. Der neue Bahnanfang 10a kann dazu beispielsweise mittels Druckluft an den neuen Wickelkern 12 geblasen werden. Aufgrund des Durchtrennens der Papierbahn 10 hinter dem Spalt 20 ist bei der Anordnung gemäß den Fig. 1 und 2 der neue Wickelkern 12 am Ende des Trennvorgangs bereits bereichsweise von dem neuen Bahn anfang 10a umschlungen, wodurch das Aufwickeln des neuen Bahnan fangs 10a auf den neuen Wickelkern 12 erleichtert wird.The paper web 10 cut at the leading edge 10 b of the new web start 10 a thus obliquely to the web running direction B is then wound onto the new winding core 12 , if necessary with the aid of suitable means. For this purpose, the new start of web 10 a can be blown onto the new winding core 12 , for example by means of compressed air. Due to the severing of the paper web 10 behind the gap 20 in the arrangement according to FIGS. 1 and 2, the new winding core 12 is already wrapped in regions at the end of the separation process by the new web beginning 10 a, whereby the winding of the new web start 10 a the new winding core 12 is facilitated.
Anstelle des Messers 24 kann die Schneidvorrichtung auch mit einem an deren Schneidewerkzeug versehen sein, beispielsweise mit einer Düse zum Ausstoßen eines Wasserstrahls unter hohem Druck, einem Laser oder ei nem rotierenden gezahnten Schneiderad.Instead of the knife 24 , the cutting device can also be provided with a cutting tool, for example with a nozzle for ejecting a water jet under high pressure, a laser or a rotating toothed cutting wheel.
Abweichend von der Ausführungsform gemäß Fig. 1 und 2 kann die Schneidvorrichtung auch schräg zur Bahnlaufrichtung B bewegt werden, wodurch - bei unveränderter Geschwindigkeit der Papierbahn 10 und des Messers 24 - der Winkel zwischen der Schnittlinie 46 und der Bahnlauf richtung B kleiner, d. h. die Papierbahn 10 spitzer geschnitten wird. . Deviating from the embodiment according to Figures 1 and 2, the cutter obliquely to the web running direction B are moved, whereby - at an unchanged speed of the paper web 10 and the blade 24 - the angle between the line of intersection 46 and the web running direction B smaller, ie, the paper web 10 is cut more pointed.
Die Wickelvorrichtung in der Ausführungsform gemäß Fig. 3 unterschei det sich von der vorstehend anhand der Fig. 1 und 2 beschriebenen Aus führung dadurch, daß zum Durchtrennen der Papierbahn 10 der neue Wickelkern 12 weiter in den Zwischenraum zwischen der Wickelrolle 16 und der Wickelwalze 18 derart hineinbewegt wird, daß die Drehachsen der Wickelkerne 12, 14 und der Wickelwalze 18 in der gleichen horizontalen Ebene liegen. Im Gegensatz zur Ausführungsform von Fig. 1 ist der neue Wickelkern 12 somit tiefer in die Papierbahn 10 eingetaucht, wobei die Papierbahn 10 den neuen Wickelkern 12 über einen Winkelbereich von beinahe 90° umschlingt.The winding device in the embodiment according to Fig. 3 below failed det from the above with reference to Fig. 1 and from 2 described management by the fact that for severing the paper web 10 of the new winding core 12 further into the intermediate space between the winding roller 16 and the winding roller 18 such is moved in that the axes of rotation of the winding cores 12 , 14 and the winding roller 18 lie in the same horizontal plane. In contrast to the embodiment of FIG. 1, the new winding core 12 is thus immersed deeper into the paper web 10 , the paper web 10 wrapping around the new winding core 12 over an angular range of almost 90 °.
Anstelle eines umlaufenden Messers ist die Schneidvorrichtung mit einer umlaufenden Düse 26 versehen, über die ein Wasserstrahl unter hohem Druck in Richtung des neuen Wickelkerns 12 ausgestoßen werden kann, welcher in der Lage ist, die Papierbahn 10 zu durchtrennen. Die Düse 26 ist so ausgerichtet, daß ein derartiger Wasserstrahl näherungsweise in ra dialer Richtung auf den neuen Wickelkern 12 zielt.Instead of a rotating knife, the cutting device is provided with a rotating nozzle 26 , through which a water jet can be expelled under high pressure in the direction of the new winding core 12 , which is able to cut through the paper web 10 . The nozzle 26 is aligned so that such a water jet is aimed approximately in ra dialer direction on the new winding core 12 .
Grundsätzlich kann die Schneidvorrichtung auch mit anderen Mitteln zum Durchtrennen der Papierbahn 10 versehen sein, z. B. mit einer La servorrichtung.In principle, the cutting device can also be provided with other means for severing the paper web 10 , e.g. B. with a La servvorrichtung.
Die Wickelkerne 12, 14 sind bevorzugt mit einem elastisch verformbaren Bezug aus Polyurethan oder einem anderen verschleißfesten Kunststoff versehen. Alternativ kann die Wickelwalze 18 einen derartigen nachgiebi gen Bezug aufweisen, während die Wickelkerne 12, 14 mit einem aus Me tall hergestelltem Bezug versehen sind.The winding cores 12 , 14 are preferably provided with an elastically deformable cover made of polyurethane or another wear-resistant plastic. Alternatively, the winding roller 18 can have such a flexible reference, while the winding cores 12 , 14 are provided with a cover made of metal.
Gemäß der in den Fig. 4 und 5 vereinfacht dargestellten Ausführungsform einer erfindungsgemäßen Wickelvorrichtung, bei der der neue Wickelkern 12 während des Durchtrennens der Papierbahn 10 bezüglich der Wickel walze 18 und des alten Wickelkerns 14 wiederum in einer Position gemäß Fig. 1 angeordnet ist, umfaßt die Schneidvorrichtung zwei Messer 24', die jeweils senkrecht zu der in Fig. 5 durch den Pfeil B angedeuteten Bahn laufrichtung in einander entgegengesetzten Richtungen bewegbar sind.According to the simplified embodiment shown in FIGS. 4 and 5 of a winding device according to the invention, in which the new winding core 12 during the severing of the paper web 10 with respect to the winding roller 18 and the old winding core 14 is again arranged in a position according to FIG. 1 the cutting device two knives 24 ', each perpendicular to the direction indicated in Fig. 5 by the arrow B running direction are movable in opposite directions.
Die in Fig. 5 nicht im einzelnen dargestellte Transporteinrichtung 36' umfaßt ein Endlosorgan, wie es in Verbindung mit den Fig. 1 und 2 er läutert worden ist und an dem die beiden Messer 24' angebracht sind.The transport device 36 'not shown in detail in FIG. 5 comprises an endless member, as has been explained in connection with FIGS . 1 and 2 and to which the two knives 24 ' are attached.
Die beiden Messer 24' sind in Bahnlaufrichtung B mit Abstand voneinan der angeordnet und werden zum Durchtrennen der Papierbahn 10 jeweils bezüglich deren Querrichtung etwa mittig angesetzt. Um die Papierbahn 10 vollständig zu durchtrennen, werden die beiden Messer 24' vorbe schleunigt und in Abhängigkeit von ihrer eigenen Geschwindigkeit sowie von der Geschwindigkeit der Papierbahn 10 derart an der Papierbahn 10 angesetzt, daß sich die beiden entstehenden Schnittlinien 46' schneiden, wie es in Fig. 5 gezeigt ist.The two knives 24 'are arranged in the web running direction B at a distance from one another and are each attached approximately centrally in order to cut through the paper web 10 with respect to its transverse direction. In order to completely cut the paper web 10 , the two knives 24 'are accelerated in advance and, depending on their own speed and on the speed of the paper web 10, are attached to the paper web 10 such that the two cutting lines 46 ' intersect, as is shown in FIG Fig. 5 is shown.
Hierdurch ergibt sich ein spitz zulaufender neuer Bahnanfang 10'a, der gegebenenfalls unter Zuhilfenahme geeigneter Mittel, beispielsweise Druckluft, auf dem neuen Wickelkern 12 aufgewickelt wird.This results in a tapering new web start 10 ′ a, which is optionally wound onto the new winding core 12 with the aid of suitable means, for example compressed air.
Die Messer 24' können auch jeweils ausgehend von einem der Ränder der Papierbahn 10 senkrecht zur Bahnlaufrichtung B in Richtung der Mitte der Papierbahn 10 wiederum derart bewegt werden, daß sich die Schnitt linien schneiden. Hierbei würde sich ein V-artig oder schwalbenschwanz artig eingeschnittener neuer Bahnanfang ergeben.The knives 24 'can also be moved in each case starting from one of the edges of the paper web 10 perpendicular to the web running direction B in the direction of the center of the paper web 10 such that the cutting lines intersect. This would result in a new V-shaped or dovetail-like incision.
Die Ausführungsform der erfindungsgemäßen Wickelvorrichtung gemäß den Fig. 6 und 7 unterscheidet sich von der Ausführungsform gemäß Fig. 1 dadurch, daß die ein Messer 24" umfassende Transporteinrichtung 36" eine Zylinder-Kolben-Einheit 28 umfaßt. Das Messer 24" ist mit einem Zylinder gekoppelt, der in einem sich senkrecht zur Bahnlaufrichtung B in einer zur Papierbahn 10 parallel verlaufenden Ebene erstreckenden Kol ben hin- und herbewegbar ist.The embodiment of the winding device according to the invention according to FIGS. 6 and 7 differs from the embodiment according to FIG. 1 in that the transport device 36 "comprising a knife 24 " comprises a cylinder-piston unit 28 . The knife 24 "is coupled to a cylinder which can be moved back and forth in a piston extending perpendicularly to the web running direction B in a plane extending parallel to the paper web 10 .
Grundsätzlich ist jede Kombination zwischen der konkreten Ausgestaltung der Schneidvorrichtung sowie der Anordnung des neuen Wickelkerns 12 bezüglich des alten Wickelkerns 14 und der Wickelwalze 18 möglich. In principle, any combination between the specific design of the cutting device and the arrangement of the new winding core 12 with respect to the old winding core 14 and the winding roller 18 is possible.
Die Transporteinrichtung der Schneidvorrichtung kann auch einen auf einer Linearführung zwangsgeführten Schlitten umfassen, der zu Beginn des Trennvorgangs impulsartig beschleunigt und über die volle Breite der Papierbahn gewissermaßen geschossen wird.The transport device of the cutting device can also be one a linear guide include positively guided carriage, the beginning of the separation process accelerated impulsively and over the full width of the Paper web is shot as it were.
Die Transporteinrichtung 36, 36', 36" der Schneidvorrichtung sowie das Betätigungsorgan 34 können mit dem neuen Wickelkern 12 - z. B. über mittels des neuen Wickelkerns 12 mitgeführte Elemente - derart gekoppelt sein, daß sich die Schneidvorrichtung beim Einschwenken des neuen Wickelkerns 12 an die Wickelwalze 18 heran - unabhängig von der Positi on des neuen Wickelkerns 12 - stets in einer optimalen Position zum Durchtrennen der Papierbahn 10 befindet.The transport device 36 , 36 ', 36 "of the cutting device and the actuating member 34 can be coupled to the new winding core 12 - for example via elements carried by means of the new winding core 12 - in such a way that the cutting device attaches itself when the new winding core 12 swings in the winding roller 18 - regardless of the position of the new winding core 12 - is always in an optimal position for severing the paper web 10 .
Ein Vorteil der Erfindung besteht darin, daß die Einschwenkbewegung des neuen Wickelkerns 12 an die Wickelwalze 18 heran für das Durchtrennen der Papierbahn 10 nicht unterbrochen werden muß. An advantage of the invention is that the pivoting-in movement of the new winding core 12 towards the winding roller 18 does not have to be interrupted for severing the paper web 10 .
