Abstract
Description
Die Erfindung betrifft ein Verfahren zum Aufwickeln einer Materialbahn, wie insbesondere einer Papier- oder Kartonbahn, auf einen Tambour, bei dem die Materialbahn über eine Tragtrommel geführt und zwischen der Tragtrommel und dem Tambour ein Wickelspalt gebildet wird und die Materialbahn für einen jeweiligen Tambourwechsel bei von der Tragtrommel abgesetztem vollem Tambour und der Tragtrommel zugeordnetem neuem, leerem Tambour durchtrennt wird. Sie betrifft ferner eine Wickelmaschine der im Oberbegriff des Anspruchs 10 angegebenen Art.The invention relates to a method for winding a material web, such as in particular a paper or cardboard web, on a reel, at which the material web is guided over a carrying drum and between the Carrier drum and the drum a winding gap is formed and the Material web for a respective reel change at the carrying drum full drum and the drum new, empty drum is cut. It also relates to a winding machine the type specified in the preamble of claim 10.
Eine entsprechende Wickelmaschine wird beispielsweise am Ende einer der Herstellung oder Veredelung einer Materialbahn dienenden Maschine eingesetzt. Sie kann beispielsweise aber auch dazu dienen, eine bereits fertig gewickelte Wickelrolle umzuwickeln. Bei der betreffenden Maschine kann es sich beispielsweise um eine Papier-, Karton- oder Tissuemaschine handeln.A corresponding winding machine is, for example, at the end of a the manufacture or refinement of a machine that serves as a material web used. However, it can also serve, for example, to already have one to wind the finished wound reel. On the machine in question it can be, for example, a paper, cardboard or tissue machine act.
Zum Trennen der Materialbahn für einen jeweiligen Tambourwechsel sind verschiedene Einrichtungen bekannt. So wird beispielsweise ein bahnbreites Abschlagmesser verwendet. Ein solches bahnbreites Abschlagmesser besitzt jedoch den Nachteil, daß die Bahn nicht von Anfang an auf den Tambour aufgeführt werden kann. Der überdies bekannte Bandwechsel weist insbesondere den Nachteil auf, daß mit dem zu verwendenden Band zusätzliches Fremdmaterial eingesetzt werden muß. Zudem kann die Verwendung eines solchen Bandes, dessen Dicke beispielsweise in einem Bereich von 0,3 bis 1,5 mm liegt, dazu führen, daß die ersten Lagen der Papierbahn infolge eines Durchdrückens beschädigt werden. Neben einem bahnbreiten Abschlagmesser oder einem Bandwechsel werden demzufolge heute zunehmend auch berührungslos arbeitende Schneideinrichtungen wie insbesondere mit Hochdruck arbeitende Wasserstrahldüsen eingesetzt. Auch bei Verwendung solcher berührungslos arbeitender Schneideinrichtungen kann es jedoch noch zu Problemen bei einem jeweiligen Trennvorgang kommen.To separate the material web for a respective reel change various institutions known. For example, a web width Tee knife used. Such a wide knife has the disadvantage, however, that the web is not on the Drum can be performed. The well-known band change has the particular disadvantage that with the tape to be used additional foreign material must be used. In addition, the use of such a band, the thickness of which, for example, is in a range is from 0.3 to 1.5 mm, cause the first layers of the paper web damage due to pushing. Besides one web-wide knives or a tape change are consequently nowadays increasingly also contactless cutting devices as used in particular with high-pressure water jet nozzles. Even when using such contactless cutting devices However, there may still be problems with each Separation process come.
Die deutsche Offenlegungsschrift DE 197 37 709 A1 offenbart eine Wickelmaschine zum Aufwickeln einer Materialbahn wie insbesondere einer Papier- oder Kartonbahn auf einen Tambour, bei der die Materialbahn über eine Tragtrommel geführt und zwischen der Tragtrommel und dem Tambour ein Wickelspalt gebildet wird und die Materialbahn für einen jeweiligen Tambourwechsel bei von der Tragtrommel abgesetztem vollem Tambour und der Tragtrommel zugeordnetem neuem, leerem Tambour durchtrennt wird.The German patent application DE 197 37 709 A1 discloses one Winding machine for winding a web of material such as in particular a paper or cardboard web on a reel, in which the Material web guided over a support drum and between the Carrier drum and the drum a winding gap is formed and the Material web for a respective reel change at von der Carrier drum full drum and the drum assigned new, empty drum is cut.
Dabei ist vorgesehen, dass mittels einer Messeinrichtung die Linienkraft (Nipkraft) im zwischen der Tragtrommel und der Wickerolle gebildeten Wickelspalt gemessen wird. Die Linienkraft wird ausschließlich durch ein Verfahren des die Tragtrommel haltenden Führungsschlittens bestimmt.It is envisaged that the line force by means of a measuring device (Nip force) in the formed between the carrier drum and the wicker roller Winding gap is measured. The line force is determined exclusively by a Method of the guide carriage holding the carrier drum is determined.
Ziel der Erfindung ist es, ein Verfahren sowie eine Wickelmaschine der eingangs genannten Art zu schaffen, mit denen ein möglichst sicherer Trennvorgang gewährleistet ist.The aim of the invention is to provide a method and a winding machine to create the kind mentioned above, with which the safest possible Separation process is guaranteed.
Hinsichtlich des Verfahrens wird diese Aufgabe erfindungsgemäß dadurch gelöst, daß der Bahnzug im Bereich zwischen dem vollen und dem neuen Tambour mittels des den vollen Tambour beaufschlagenden Drehmoments in Abhängigkeit von der aktuellen Position wenigstens eines allgemein quer zur Bahnlaufrichtung verfahrbaren Schneidelements so gesteuert und/oder geregelt wird, daß er während dieses Trennvorgangs unterhalb eines kritischen Wertes gehalten wird, ab dem es im Bereich zwischen dem vollen und dem neuen Tambour zu einem unkontrollierten Reißen der Materialbahn kommen kann.With regard to the method, this object is achieved according to the invention solved, that the train in the area between the full and the new drum by means of the torque acting on the full drum in Dependence on the current position of at least one generally transverse to Cutting elements movable and / or controlled in this way it is regulated that during this separation process it is below a critical Value is held, from which it is in the range between the full and the new drum for an uncontrolled tearing of the material web can come.
Aufgrund dieser Ausbildung ist bei jedem Tambourwechsel stets ein äußerst sicherer und zuverlässiger Trennvorgang gewährleistet. Ein unkonrolliertes Reißen der Materialbahn im Bereich zwischen dem vollen und dem neuen Tambour ist praktisch ausgeschlossen. Der kritische Wert kann beispielsweise anhand von Versuchen ermittelt werden.Because of this training, there is always an extreme with every reel change safe and reliable separation process guaranteed. An uncontrolled Tear the web in the area between the full and the new drum is practically impossible. The critical value can be determined, for example, using tests.
Die Materialbahn wird vorzugsweise mittels wenigstens eines allgemein quer zur Bahnlaufrichtung verfahrbaren Schneidelements durchtrennt.The material web is preferably made general by means of at least one Cutting elements which can be moved transversely to the web running direction are severed.
Bei einer bevorzugten praktischen Ausführungsform wird die Materialbahn mittels wenigstens eines berührungslos arbeitenden Schneidelements durchtrennt. Dabei können beispielsweise mit Hochdruck arbeitende Wasserstrahldüsen oder beispielsweise auch eine Laserschneideinrichtung verwendet werden.In a preferred practical embodiment, the material web by means of at least one contactless cutting element severed. For example, those working with high pressure Water jet nozzles or, for example, a laser cutting device be used.
In bestimmten Fällen ist es von Vorteil, wenn das den vollen Tambour beaufschlagende Drehmoment mit dem Beginn des Trennvorgangs auf den Wert Null heruntergefahren wird.In certain cases it is an advantage if the full drum is applied Torque at the start of the separation process Value zero is shut down.
Der volle Tambour wird nach vollendetem Trennvorgang zweckmäßigerweise abgebremst.The full reel is expedient after the separation process has been completed braked.
In bestimmten Fällen ist es auch von Vorteil, wenn das den vollen Tambour
beaufschlagende Drehmoment mit dem Beginn des Trennvorgangs
innerhalb eines vorgebbaren Zeitraumes linear auf den Wert Null heruntergefahren
wird. Das Drehmoment kann somit beispielsweise längs einer
entsprechenden linearen Rampe heruntergesteuert und/oder heruntergeregelt
werden.
Für den genannten Zeitraum wird vorteilhafterweise ein Wert von 0,2
bis 1 s und vorzugsweise ein Wert von etwa 0,4 s gewählt.In certain cases, it is also advantageous if the torque acting on the full drum is reduced linearly to zero within a predeterminable period of time when the separation process begins. The torque can thus be stepped down and / or regulated down along a corresponding linear ramp, for example.
A value of 0.2 to 1 s and preferably a value of approximately 0.4 s is advantageously selected for the period mentioned.
Von Vorteil ist auch, wenn der volle Tambour abgebremst wird, sobald das ihn beaufschlagende Drehmoment den Wert Null erreicht hat.It is also an advantage if the full reel is braked as soon as that torque acting on it has reached zero.
In bestimmten Fällen kann es von Vorteil sein, wenn die Bahnspannung vor und / oder nach der Tragtrommel vorzugsweise mittels Pendelwalzen reduziert wird.In certain cases it can be beneficial if the web tension before and / or after the carrier drum, preferably by means of pendulum rollers is reduced.
Bei einer weiteren zweckmäßigen Ausführungsform wird die Bahnspannung mittels einer in Bahnlaufrichtung vor der Tragtrommel liegenden Einrichtung, vorzugsweise mittels einer eine gezielte Beeinflussung der Spannung in den einzelnen Zonen ermöglichenden Breitstreckwalze oder einer sektionierten Walze, sektional beinflußt.In a further expedient embodiment, the web tension by means of a lying in front of the carrier drum in the direction of web travel Device, preferably by means of a targeted influence on the Spreader roll or to allow tension in the individual zones a sectioned roller, influenced sectionally.
Grundsätzlich ist es auch möglich, den Bahnzug über die Tragtrommel zu steuern und/oder zu regeln.In principle, it is also possible to pull the web tension over the carrying drum control and / or regulate.
Die erfindungsgemäße Wickelmaschine ist dadurch gekennzeichnet, daß eine Steuer- und/oder Regeleinrichtung vorgesehen ist, durch die der Bahnzug im Bereich zwischen dem vollen und dem neuen Tambour mittels des den vollen Tambour beaufschlagenden Drehmoments in Abhängigkeit von der aktuellen Position wenigstens eines allgemein quer zur Bahnlaufrichtung verfahrbaren Schneidelements so steuerbar und/oder regelbar ist, daß dieser während des Trennvorgangs unterhalb eines kritischen Wertes gehalten wird, ab dem es im Bereich zwischen dem vollen und dem neuen Tambour zu einem unkontrollierten Reißen der Materialbahn kommen kann.The winding machine according to the invention is characterized in that that a control and / or regulating device is provided, through which the Train in the area between the full and the new drum by means of of the torque acting on the full drum depending on of the current position of at least one generally transverse to the web running direction movable cutting elements is so controllable and / or adjustable that this during the separation process below a critical value from which it is held in the range between the full and the new Drum come to an uncontrolled tearing of the material web can.
