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 zumindest teilweise durchtrennt wird, indem mittels wenigstens einer berührungslos arbeitenden Schneideinrichtung ein insbesondere spitzer neuer Bahnanfang geschnitten wird, wobei zum Durchtrennen der Materialbahn zusätzlich wenigstens ein Trennelement verwendet wird. Sie betrifft ferner eine Wickelmaschine der im Oberbegriff des Anspruchs 13 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 least partially is severed by using at least one non-contact Cutting device a particularly pointed new beginning of the path is cut, in addition to cutting the material web used at least one separating element becomes. It also relates to a winding machine in the preamble of claim 13 specified Art.
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.
Eine Wickelmaschine der eingangs genannten Art ist aus der EP 0 543 788 A 1 bekannt. Bei dieser bekannten Wickelmaschine ist als berührungslos arbeitende Schneideinrichtung beispielsweise eine Wasserstrahlschneideinrichtung vorgesehen. A winding machine of the type mentioned is from EP 0 543 788 A1. In this known winding machine is considered to be non-contact working cutting device, for example a water jet cutting device intended.
Mit einer berührungslos arbeitenden Schneideinrichtung kann die Materialbahn geschnitten werden, ohne daß dabei der Bahnlauf gestört wird. Es ist beispielsweise auch möglich, die Materialbahn direkt auf der Tragtrommel zu schneiden, wodurch eine stabilere Bahnführung erreicht wird. Mit einer solchen berührungslos arbeitenden Schneideinrichtung können jedoch Probleme hinsichtlich der Betriebssicherheit und der Zuverlässigkeit des Trennvorgangs beim Tambourwechsel während des Aufwickelns der Bahn auftreten. Die Zuverlässigkeit der berührungslos arbeitenden Schneideinrichtungen ist in vielen Fällen unzureichend. So können beispielsweise bei einer Wasserstrahlschneideinrichtung die Wasserstrahldüsen verstopfen oder sich belegen. Dies führt zu einer Reduzierung des Strahlimpulses und damit zu einer Verminderung der Schnittleistung. Die Folge ist ein fehlerhafter Trennvorgang, der einen entsprechend höheren Papierausschuß mit sich bringt und die Produktivität der gesamten Papiermaschine und/oder Streichmaschine verringert.The material web can be cut with a contactless cutting device be cut without disturbing the web run. For example, it is also possible to place the material web directly on the carrying drum to cut, whereby a more stable web guidance is achieved. With such a non-contact cutting device however, operational safety and reliability problems the separation process when changing the reel during winding occur on the web. The reliability of the contactless working Cutting devices are inadequate in many cases. For example in the case of a water jet cutting device, the water jet nozzles clog up or become occupied. This leads to a reduction in the Beam pulse and thus to a reduction in the cutting performance. The The result is an incorrect separation process, which is a correspondingly higher one Paper waste and the productivity of the entire paper machine and / or coating machine reduced.
Weiterhin offenbart die deutsche Offenlegungsschrift DE 35 15 519 A1 ein Verfahren zum Aufwickeln einer Materialbahn, insbesondere 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. Die Materialbahn wird für einen jeweiligen Tambourwechsel zumindest teilweise durchtrennt, indem mittels wenigstens einer berührungslos arbeitenden Schneideinrichtung ein insbesondere spitzer neuer Bahnanfang geschnitten wird. Mittels einem berührenden Trennelement wird anschließend die Materialbahn mit einem Schrägschnitt in ihrer vollen Breite getrennt.Furthermore, the German patent application DE 35 15 519 discloses A1 a method for winding a material web, in particular Paper or cardboard web, on a drum where the Material web guided over a support drum and between the Carrier drum and the drum a winding gap is formed. The Material web is at least for a respective reel change partially severed by using at least one non-contact working cutting device a particularly pointed new The beginning of the web is cut. By means of a touching The material web is then separated with a Bevel cut separated in its full width.
Die genannte Schrift offenbart weiterhin einen Tragtrommel-Rollapparat zur Durchführung des beschriebenen Verfahrens.The cited document also discloses a carrier drum trolley to carry out the described method.
Ziel der Erfindung ist es, ein Verfahren sowie eine Wickelmaschine der eingangs genannten Art zu schaffen, die einen verbesserten Wirkungsgrad des Trennvorgangs und damit eine insgesamt höhere Produktivität der betreffenden Maschine gewährleisten.The aim of the invention is to provide a method and a winding machine to create an improved efficiency of the separation process and thus an overall higher productivity of the ensure the machine in question.
Hinsichtlich des Verfahrens wird diese Aufgabe erfindungsgemäß dadurch gelöst, daß wenigstens ein bahnbreit wirkendes Trennelement verwendet wird.With regard to the method, this object is achieved according to the invention solved that at least one railroad acting Separating element is used.
Aufgrund dieser Ausbildung wird ein wesentlich höherer Wirkungsgrad des Trennvorgangs erreicht, was eine entsprechend höhere Produktivität der betreffenden Papier- bzw. Streichmaschine mit sich bringt. Die erzielten Vorteile kommen insbesondere bei höheren Geschwindigkeiten zum Tragen. Als Trennelement kann beispielsweise ein Abschlagmesser oder dergleichen verwendet werden.Due to this training, a much higher efficiency of the separation process, which results in a correspondingly higher productivity the relevant paper or coating machine. The achieved Advantages come in particular at higher speeds Wear. For example, a cutting knife or the like can be used.
Dabei kann durch die berührungslos arbeitende Schneideinrichtung beispielsweise auch nur eine Teiltrennung erfolgen. So ist es beispielsweise möglich, daß das erste Trennelement, d.h. die berührungslos arbeitende Schneideinrichtung noch aktiv ist, während das zweite Trennelement bereits in Betrieb genommen wird. In diesem Fall hat das erste Trennelement noch keine Volltrennung der Materialbahn vollzogen.The contactless cutting device can, for example even a partial separation. For example, it is possible that the first separator, i.e. the contactless one Cutting device is still active while the second separating element is already is put into operation. In this case, the first separator the material web has not yet been completely separated.
Als berührungslos arbeitende Schneideinrichtung kann beispielsweise eine Wasserstrahlschneideinrichtung, eine Luftstrahlschneideinrichtung, eine Laserschneideinrichtung und/oder dergleichen verwendet werden.As a non-contact cutting device, for example Water jet cutting device, an air jet cutting device, a laser cutting device and / or the like can be used.
In bestimmten Fällen ist es zweckmäßig, wenn die Materialbahn mittels der berührungslos arbeitenden Schneideinrichtung in Bahnlaufrichtung vor der Tragtrommel geschnitten wird.In certain cases, it is useful if the material web by means of the contactless cutting device in the direction of web travel is cut before the carrier drum.
Die Materialbahn kann jedoch mittels der berührungslos arbeitenden Schneideinrichtung auch auf der Tragtrommel geschnitten werden.However, the material web can be operated by means of the non-contact method Cutting device can also be cut on the carrier drum.
In bestimmten Fällen kann es auch von Vorteil sein, wenn die Materialbahn mittels der berührungslos arbeitenden Schneideinrichtung an dem neuen, noch leeren Tambour geschnitten wird. In certain cases it can also be advantageous if the material web by means of the contactless cutting device on the new, still empty drum is cut.
Das Trennelement kann beispielsweise in Bahnlaufrichtung unmittelbar nach dem Wickelspalt eingesetzt werden.The separating element can, for example, directly in the direction of web travel after the winding gap.
Bei einer zweckmäßigen praktischen Ausführungsform wird das Trennelement in Bahnlaufrichtung nach der berührungslos arbeitenden Schneideinrichtung eingesetzt. In diesem Fall kann das Trennelement stets nach Ablauf einer bestimmten Zeitdauer, spätestens nach 0 bis 5 s, vorzugsweise nach 1 bis 3 s nach einer Aktivierung der berührungslos arbeitenden Schneideinrichtung (24) aktiviert werden. In bestimmten Fällen kann es jedoch auch zweckmäßig sein, wenn mittels wenigstens eines Sensors der durch die berührungslos arbeitende Schneideinrichtung bewirkte Schneidvorgang überwacht und das Trennelement insbesondere über eine Steuer- und/oder Regeleinrichtung jeweils nur dann aktiviert wird, wenn zuvor ein fehlerhafter Schneidvorgang erfaßt wurde.In an expedient practical embodiment, the separating element in the web running direction after the non-contact Cutting device used. In this case, the separating element always after a certain period of time, at the latest after 0 to 5 s, preferably after 1 to 3 s after activation of the contactless working Cutting device (24) can be activated. In certain cases However, it may also be appropriate if at least one Sensor caused by the contactless cutting device The cutting process is monitored and the separating element in particular activated only then via a control and / or regulating device if a faulty cutting process was previously detected.
Von Vorteil ist auch, wenn mittels wenigstens eines Sensors zumindest ein Betriebsparameter der berührungslos arbeitenden Schneideinrichtung überwacht wird. So kann beispielsweise im Fall einer Wasserstrahldüse zum Beispiel der Druck überwacht werden.It is also advantageous if at least one is used by means of at least one sensor Operating parameters of the contactless cutting device is monitored. For example, in the case of a water jet nozzle for example the pressure can be monitored.
Alternativ oder zusätzlich kann auch mittels wenigstens eines Sensors die Aufwicklung auf den neuen Tambour überwacht werden. Dabei kann beispielsweise ein optischer Sensor vorgesehen sein und beispielsweise eine Grauwertmessung durchgeführt werden.As an alternative or in addition, the Winding on the new drum are monitored. For example an optical sensor and, for example, a Gray value measurement can be carried out.
Zweckmäßigerweise wird das Trennelement in Bahnlaufrichtung vor der berührungslos arbeitenden Schneideinrichtung und vorzugsweise über einem Ausschußauflöser eingesetzt. Dies hat zur Folge, daß die Materialbahn neu überführt und auf den Tambour aufgeführt werden muß.The separating element is expediently placed in front of the web running direction contactless cutting device and preferably over a committee dissolver used. This has the consequence that the material web newly transferred and performed on the drum.
Die erfindungsgemäße Wickelmaschine ist entsprechend dadurch gekennzeichnet, daß zum Durchtrennen der Materialbahn wenigstens ein bahnbreit wirkendes Trennelement vorgesehen ist.The winding machine according to the invention is accordingly characterized in that that at least to cut the web of material a separating element that acts as wide as the web is provided.
Das Trennelement kann zwischen einer dem Durchtrennen der Materialbahn dienenden Betriebsstellung und einer Ruhestellung verschwenkbar sein.The separating element can be between the severing of the material web serving operating position and a rest position pivotable his.
