Abstract

PCT No. PCT/EP94/03835 Sec. 371 Date Nov. 21, 1996 Sec. 102(e) Date Nov. 21, 1996 PCT Filed Nov. 19, 1994 PCT Pub. No. WO95/13980 PCT Pub. Date May 26, 1995A winding machine for winding webs, such as paper webs which may be longitudinally slit, has two support rollers (TW1 and TW2) that carry the roll being produced (R; R'; R'', R''') in a winding bed formed between the support rollers. Both support rollers have elastic casings (M1 and M2) which are however deformable to a different extent. One of the support rollers is partially surrounded by the web during winding. In order to further optimize the winding quality, even in the case of heavy wound web rolls, the support roller (M1) subjected to the highest total load, that results both from static and dynamic loads during winding, has the most elastically deformable casing. Such a winding machine is preferably developed so that the space (DR) delimited by both support rollers (TW1 and TW2) and the already partially produced wound web roll (R) is sealed as much as possible at its ends and from below. An overpressure can be generated in the space (DR) for relieving the inherent weight of the roll (R). This combination of measures substantially prevent undesirable inclusion of air.

Description

Die Erfindung betrifft eine Wickelmaschine zum Aufwickeln, von ggf. längsgeteilten Bahnen, vorzugsweise Papierbahnen, mit den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to a winding machine for winding, of possibly longitudinally divided webs, preferably paper webs, with the features of the preamble of claim 1.

Um bei immer schwerer werdenden zu wickelnden Rollen ein möglichst gleichmäßiges Wickelergebnis, d. h. eine möglichst gleichmäßige Rollenstruktur zu erreichen und Wickelfehler zu minimieren, ist es bekannt, zumindest eine der vorzugsweise zwei Tragwalzen mit einem elastisch verformbaren Mantel zu versehen. Die möglichen Kombinationen sind in der DE 92 04 667 U beschrieben. Gemäß dieser Druckschrift sollen die besten Wickelergebnisse dann erzielt werden, wenn folgende Merkmalskombination für eine derartige Tragwalzenanordnung realisiert ist:

  • Das Wickelbett wird ausschließlich aus den beiden Tragwalzen gebildet,
  • die in Bahnlaufrichtung zweite Tragwalze weist einen Mantel auf, der wesentlich stärker verformbar ist, als der Mantel der in Bahnlaufrichtung ersten Tragwalze,
  • die in Bahnlaufrichtung zweite Tragwalze ist gegenüber der in Bahnlaufrichtung ersten Tragwalze abgesenkt, so daß eine durch die Achsen der beiden Tragwalzen gelegte Ebene mit der Horizontalen einen Winkel bildet.
In order to achieve a winding result that is as uniform as possible, ie a roller structure that is as uniform as possible, and to minimize winding errors in the case of rolls that are becoming ever heavier to be wound, it is known to provide at least one of the preferably two support rollers with an elastically deformable jacket. The possible combinations are described in DE 92 04 667 U. According to this publication, the best winding results should be achieved if the following combination of features is realized for such a roller arrangement:
  • The changing bed is made up exclusively of the two support rollers,
  • the second support roller in the web running direction has a jacket which is much more deformable than the jacket of the first support roller in the web running direction,
  • the second support roller in the direction of web travel is lowered relative to the first support roller in the direction of web travel, so that a plane through the axes of the two support rollers forms an angle with the horizontal.

Es wurde gefunden, daß diese bekannte Tragwalzenanordnung nur in Ausnahmefällen wirklich zufriedenstellende Wickelergebnisse ermöglicht. It has been found that this known roller arrangement only in exceptional cases really satisfactory winding results enables.

Davon ausgehend liegt der Erfindung die Aufgabe zugrunde, eine gattungsgemäße Wickelmaschine dahingehend zu verbessern, daß die Wickelqualität auch bei großen Rollengewichten weiter optimiert wird.Proceeding from this, the object of the invention is to improve a generic winding machine to the effect that the winding quality is further optimized even with large roll weights.

Zur Lösung dieser Aufgabe wird eine Wickelmaschine mit den Merkmalen des Anspruchs 1 vorgeschlagen.To solve this problem, a winding machine with the features of claim 1 is proposed.

Die Erfindung hat erstmals erkannt, daß die dynamische Tragwalzenbelastung beim Wickeln bei der Festlegung der Nachgiebigkeit bzw. Starrheit der Tragwalzenoberfläche berücksichtigt werden muß. Es hat sich gezeigt, daß die aus dynamischer und statischer Belastung resultierende Gesamtbelastung der von der ankommenden Bahn teilweise umschlungenen, d. h. in Bahnlaufrichtung ersten Tragwalze in aller Regel relativ höherals die der anderen Tragwalze ist.The invention recognized for the first time that the dynamic load on the roller when winding when setting the compliance or rigidity of the support roller surface is taken into account must become. It has been shown that the dynamic and total load resulting from static load the incoming train partially wrapped, d. H. in the direction of web travel first support roller is generally relatively higher than that of the other carrier roller.

Eine weitere wesentliche Verbesserung des Wickelergebnisses läßt sich dadurch erzielen, daß die in Bahnlaufrichtung zweite Tragwalze im Bereich ihrer von der Bahn berührter Oberfläche einen relativ höhere- Reibwert aufweist, als die entsprechende Oberfläche der in Bahnlaufrichtung ersten Tragwalze. Insbesondere in Kombination mit dem Merkmal des Anspruchs 1 oder 2 läßt sich nierdurch das Maß des Spanners oder Entlastens der Papierbahn an der äußeren Rollenoberfläche in optimaler Weise einstellen bzw. vorgeben. Besonders bevorzugt ist eine solche Ausführungsform, bei der die Gewichtsbelastung der in Bahnlaufrichtung zweiten Tragwalze im Vergleich zur Gewichtsbelzstung der in Bahnlaufrichtung ersten Tragwalze besonders klein ist.Another significant improvement in the winding result can be achieved in that the web running direction second support roller in the area of their touched by the web Surface has a relatively higher coefficient of friction than that corresponding surface of the first in the direction of web travel Carrier roller. Especially in combination with the feature of Claim 1 or 2 can be determined by the size of the tensioner or relieving the paper web on the outer roll surface set or specify in an optimal manner. Especially such an embodiment is preferred in which the Weight load of the second support roller in the direction of web travel compared to the weight load in the direction of web travel first carrier roller is particularly small.

Nach einer weiteren Ausführungsform der Erfindung ist vorgesehen, den durch die Tragwalzen und dem bereits zum Teil hergestellten Wickel begrenzten Raum über den zwischen den Tragwalzen gebildeten Spalt mit einem Gasdruck in im übrigen bekannter Weise zu beaufschlagen und somit eine Entlastung des Eigengewichtes des Wickels zu bewirken (Anspruch 4). Es versteht sich, daß zu diesem Zweck vor allem die Stirnenden des druckbeaufschlagten Raumes in geeigneter Weise abgedichtet werden, damit sich der Entlastungsdruck aufbauen kann. Ein derartiger, sogenannter Airlift ist für Doppeltragwalzenroller mit relativ unelastischen Tragwalzenoberflächen seit langem bekannt, u. a. aus der US-A-3 346 209 der Anmelderin sowie der US-A-3 497 151, der DE-C-1 047 001, der DE-C-1 111 496 und der DE-U-92 01 791.According to a further embodiment of the invention, by the support rollers and already partially manufactured wrap limited space over the between the Carrier rolls formed gap with a gas pressure in the rest to act in a known manner and thus a discharge to cause the dead weight of the winding (claim 4). It it goes without saying that for this purpose especially the forehead of the pressurized space sealed in a suitable manner so that the relief pressure can build up. Such a so-called airlift is for double carrier roller rollers with relatively inelastic carrier roller surfaces long known u. a. from the applicant's US-A-3,346,209 as well as US-A-3 497 151, DE-C-1 047 001, the DE-C-1 111 496 and DE-U-92 01 791.

Bei diesen bekannten Airlift-Vorrichtungen für Doppeltragwalzenroller kommt es darauf an, einen möglichst gleichmäßigen Spalt zwischen der Oberfläche der bereits gewickelten Rolle und der von der zugeführten Bahn umschlungenen Tragwalze zu erzielen, weil ansonsten das Druckentlastungsfluid von der einzuwickelnden Bahn eingezogen und zwischen dieser und der gewickelten Rolle eingeschlossen wird.In these known airlift devices for double carrier roller rollers the important thing is to be as even as possible Gap between the surface of the already wound Roll and the support roller wrapped by the fed web to achieve, because otherwise the pressure relief fluid pulled in by and between the web to be wrapped and the wound roll is included.

Die Erfindung hat erkannt, daß dieser Spalt nur dann gleichmäßig erhalten werden kann, wenn die zu wickelnde Bahn hinreichend porös ist, um die eingezogene Druckluft durchtreten zu lassen. In den meisten Fällen wirken sich Unregelmäßigkeiten in der Oberfläche der bereits gewickelten Rolle entlang der Berührungslinie zu der umschlungenen Tragwalze äußerst negativ auf die Menge der miteingezogenen Druckentlastungsluft aus. Bei der erfindungsgemäßen Kombination führt die Nachgiebigkeit der Ummantelung der von der zugeführten Bahn umschlungenen Tragwalze dazu, daß sich die Walzenoberfläche entlang der Berührungslinie mit der bereits gewickelten Rolle an die Welligkeit der Rolle in dieser Berührungslinie anpaßt. Hierdurch werden mögliche Lufteinzugsspalte zwischen der eingezogenen Bahn und der gewickelten Rolle minimiert und damit die eingezogene Luft auf ein verträgliches Maß (Menge) reduziert. - Es versteht sich, daß die erfindungsgemäße Kombination eines Airliftes mit einer nachgiebigen Ummantelung der umschlungenen Tragwalze auch dann höchst vorteilhaft einsetzbar ist, wenn die nicht umschlungene (zweite) Tragwalze eine harte, anstelle einer nachgiebigen, Ummantelung aufweist.The invention has recognized that this gap is only even then can be obtained if the web to be wound is sufficient is porous to penetrate the compressed air allow. In most cases there are irregularities along the surface of the roll already wound the line of contact to the wrapped roller extremely negative on the amount of pressure relief air drawn in out. In the combination according to the invention leads to the flexibility of the sheathing supplied by the Web wrapped support roller so that the roller surface along the line of contact with the already wound roll to the waviness of the roll in this line of contact adjusts. This causes possible air intake gaps between the drawn web and the wound Role minimized and thus the drawn air to a tolerable Measure (quantity) reduced. - It goes without saying that the combination of an air lift with a compliant sheathing of the wrapped support roller too can be used most advantageously if the non-wrapped one (second) support roller a hard one instead of one compliant, encased.

Die vorgenannten, erfindungsgemäß zu verwendenden Bauteile unterliegen in ihrer Größe, Formgestaltung, Materialauswahl und technischen Konzeption keinen besonderen Ausnahmebedingungen, so daß die in dem jeweiligen Anwendungsgebiet bekannten Auswahlkriterien uneingeschränkt Anwendung finden können.The aforementioned components to be used according to the invention are subject to their size, shape, material selection and technical conception no special exceptions, so that those known in the respective field of application Unreservedly apply selection criteria can.

Weitere Einzelheiten, Merkmale und Vorteile des Gegenstands der Erfindung ergeen sich aus der nachfolgenden Beschreibung der zugehörigen Zeichnung, in der - beispielhaft - eine bevorzugte Ausführungsform einer erfindungsgemäßen Vorrichtung dargestellt ist.Further details, features and advantages of the item the invention emerge from the following description the accompanying drawing, in which - by way of example - a preferred one Embodiment of a device according to the invention is shown.

Bei der Ausführungsform gemäß Fig. 1 sind zwei im Durchmesser gleiche angetriebene Tragwalzen TW1 und TW2 vorgesehen, die beide eine nachgiebig verformbare Ummantelung M1, M2 aufweisen, wobei die Ummantelung M1 den relative nachgiebigeren und die Ummantelung M2 den relative weniger nachgiebigen Belag bildet. Die zugeführte Papierbahn PB umschlingt die erste Tragwalze TW1 etwa 180° und wird zu der Rolle R mit dem Rollengewicht G gewickelt. Für den Start jedes Wickelvorganges kann die Gewichtsbelastung auf die beiden Tragwalzen durch eine Belastungswalze, wie an sich bekannt, künstlich erhöht werden (GBLW). Die durch das Rollengewicht auf die beiden Tragwalzen ausgeübte Normalbelastung N1 und N2 ist bei diesem Ausführungsbeispiel gleich groß. Die dynamische Belastung der umschlungenen Walze TW1 und damit die Gesamtbelastung dieser Walze ist allerdings höher als die der Walze TW2.1 are two in diameter same driven carrier rollers TW1 and TW2 are provided, which both have a resiliently deformable casing M1, M2, the casing M1 being the relatively more compliant and the casing M2 forms the relatively less compliant covering. The fed paper web PB wraps around the first support roller TW1 about 180 ° and becomes the roll R with the roll weight G wrapped. The weight load can be used to start each winding process onto the two support rollers by a loading roller, as known per se, can be artificially increased (GBLW). The by the roll weight on the two support rollers Exerted normal load is N1 and N2 in this embodiment same size. The dynamic load of the wrapped roller TW1 and thus the total load of this However, the roller is higher than that of the roller TW2.

Ein als AL bezeichnetes Gehäuse eines an sich bekannten Airliftes ist von unten im wesentlichen randdichtend in der unteren Zwickelbereich zwischen den beiden Tragwalzen eingeführt. Durch den achsparallelen Austrittsspalt kann Druckluft, die dem Airliftgenäuse in nicht dargestellter Weise zugeführt wird, durch den Abstangsspalt zwischen den beiden Tragwalzen in den darüber liegenden, oben von der Rolle R abgedichteten Raum als Gewichtentlastungsdruckluft einströmen, wobei die Stirnseiten dieses Druckentlastungsrsumes DR in bekannter Weise abgedichtet sind.A housing called AL of a known airlift is essentially edge sealing from below lower gusset area between the two support rollers. Due to the axially parallel outlet gap, compressed air, the Airliftgenäuse in a manner not shown is fed through the tap gap between the two Carrier rollers in the above, from the roll R above inflow sealed space as weight relief compressed air, the end faces of this pressure relief space DR are sealed in a known manner.

Die Ausführungsform nach Fig. 2 unterscheidet sich von der nach Fig. 1 u. a. dadurch, daß der Durchmesser der umschlungenen Tragwalze TW1 größer als der Durchmesser der Tragwalze TW2 ist und die Achse der letzteren höher als die der ersteren gelegen ist, wobei die Belastungswalze mit einem Winkel zur Vertikalen wirksam wird. Durch diese Anordnung ist die Normalbelastung N1 der Tragwalze TW1 spürbar größer als die Normalbelastung N2 der Tragwalze TW2. Bei dieser besonders bevorzugten Ausführungsform ist die Oberfläche der nicht umschlungenen Tragwalze TW2 mit einem ihren Reibwert erhöhenden Belag RB versehen. Ein Airlift ist lediglich als Option und daher gestrichelt dargestellt.The embodiment of FIG. 2 differs from that 1 and. a. in that the diameter of the wrapped Carrier roller TW1 larger than the diameter of the carrier roller TW2 is and the axis of the latter is higher than that of the former is located, the load roller at an angle to the vertical. With this arrangement the Normal load N1 of the support roller TW1 noticeably larger than that Normal load N2 of the support roller TW2. With this especially preferred embodiment is the surface of the non-wrapped Carrier roller TW2 with a friction coefficient increasing Cover RB provided. An airlift is only an option and therefore shown in dashed lines.

Die Darstellung in Fig. 3 verdeutlicht, wie die stark übertrieben dargestellte Welligkeit der gewickelten Rolle R von dem nachgiebig verformbaren Mantel M1 der Tragwalze TW1 nachgebildet und Lufteinzugsspalte somit minimiert oder unterdrückt werden.The illustration in Fig. 3 illustrates how the greatly exaggerated shown ripple of the wound roll R of reproduced the resiliently deformable jacket M1 of the support roller TW1 and air intake gaps are thus minimized or suppressed become.
