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

Wickelmaschine Winding machine
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, 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 Wickel ergebnisse dann erzielt werden, wenn folgenαe Merkmalskombination für eine derartige Tragwal zeπanordπung realisiert ist:In order to ensure that the winding result is as uniform as possible, in the case of rolls that are becoming increasingly heavy, H. To achieve a roll structure that is as uniform as possible and to minimize winding errors, 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 are to be achieved if the following combination of features is implemented for such a supporting roller arrangement:
- Das Wickelbett wird ausschließlich aus den beiden Tragwal¬ zen gebil det ,The winding bed is formed exclusively from the two support rollers,
- die in Bahnlaufrichtung zweite Tragwalze weist einen Man¬ tel auf, der wesentlich stärker verformbar ist, als der Mantel der in Bahnlaufrichtung ersten Tragwalze,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,
- die in Bahnlaufrichtung zweite Tragwalze ist gegenüber der in Bahnlaufrichtuπg ersten Tragwalze abgesenkt, so daß ei¬ ne durch die Achsen der beiden Tragwalzen gelegte Ebene mit der Horizontalen einen Winkel bildet.- The second support roller in the web running direction is lowered compared to the first support roller in the web running direction, so that a plane through the axes of the two support rollers forms an angle with the horizontal.
Es wurde gefunden, daß diese bekannte Tragwal zenanordπung nur in Ausnahmefällen wirklich zufriedenstellende Wickeler¬ gebnisse ermöglicht.It has been found that this known supporting roller arrangement only allows truly satisfactory winding results in exceptional cases.
ORIGINALUNTERLAGEN Davon ausgehend liegt der Erfindung die Aufgabe zugrunde, eine gattungsge aße Wickelmaschine dahingehend zu verbes¬ sern, daß die Wickelqual itat auch bei großen Ro engewichten weiter optimiert wird.ORIGINAL DOCUMENTS Proceeding from this, the object of the invention is to improve a generic winding machine in such a way that the winding quality is further optimized even with large 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 Trag¬ walzenbelastung beim Wickeln bei der Festlegung der Elasti¬ zität bzw. Starrheit der Tragwalzenoberfl aehe 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 Bahn¬ laufrichtung ersten Tragwalze in aller Regel relativ hoher als die der anderen Tragwalze ist (Anspruch 2) .The invention has for the first time recognized that the dynamic load on the roller during winding must be taken into account when determining the elasticity or rigidity of the surface of the roller. It has been shown that the total load resulting from dynamic and static loading of the incoming web partially entwined, d. H. in the web running direction of the first carrier roller is generally relatively higher than that of the other carrier roller (claim 2).
Eine weitere wesentliche Verbesserung des Wickelergebnisses laßt sich dadurch erzielen, daß die in Bahnlaufrichtung zweite Tragwalze im Bereich inrer von der Bahn berührten Oberflache einen relativ höheren Reibwert aufweist, als die entsprechende Oberflache der in Bahnlaufrichtung ersten Tragwalze. Insbesondere in Kombination mit dem Merkmal des Anspruchs 1 oder 2 laßt sich hierdurch das Maß des Spannens oder Entlastens der Papierbahn an der äußeren Rollenober¬ flache in optimaler Weise einstellen bzw. vorgeben. Beson¬ ders bevorzugt ist eine solche Ausfuhrungsform, bei der die Gewichtsbelastung der in Bahnlaufrichtung zweiten Tragwalze im Vergleich zur Gewichtsbelastung der in Bahnlaufrichtung ersten Tragwalze besonαers klein ist.A further significant improvement in the winding result can be achieved in that the second support roller in the web running direction has a relatively higher coefficient of friction in the area of its surface touched by the web than the corresponding surface of the first support roller in the web running direction. In particular in combination with the feature of claim 1 or 2, the degree of tensioning or unloading of the paper web on the outer roller surface can hereby be set or specified in an optimal manner. Such an embodiment is particularly preferred in which the weight load of the second support roller in the web running direction is particularly small compared to the weight load of the first support roller in the web travel direction.
Nach einer weiteren Ausfuhruπgsfor der Erfindung ist vorge¬ sehen, 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 Stirnendeπ des druckbeaufschlagten Raumes in geeigneter Weise abgedich¬ tet werden, damit sich der Entlastungsdruck aufbauen kann. Ein derartiger, sogenannter Airlift ist für Doppeltragwal - zenroller mit relativ unelastischen Tragwalzenoberf ächen seit langem bekannt, u. a. aus der US-A-3 346 209 der Anmel¬ derin 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, it is provided that the space delimited by the support rollers and the winding that has already been produced in part over the space between the To act upon the support rollers formed gap with a gas pressure in the otherwise known manner and thus to relieve the dead weight of the winding (claim 4). It goes without saying that, for this purpose, in particular the front ends of the pressurized space are sealed in a suitable manner so that the relief pressure can build up. Such a so-called airlift has long been known for double carrier roller rollers with relatively inelastic carrier roller surfaces, inter alia from US Pat. No. 3,346,209 by the applicant and US Pat. No. 3,497,151, DE-C-1,047 001, DE-C-1 111 496 and DE-U-92 01 791.
Bei diesen bekannten Airlift-Vorrichtungen für Doppeltrag¬ walzenroller kommt es darauf an, einen möglichst gleichmäßi¬ gen Spalt zwischen der Oberfläche der bereits gewickelten Rolle und der von der zugeführten Bahn umschlungenen Trag¬ walze zu erzielen, weil ansonsten das Druckentl astungsf1 uid von der einzuwickelnden Bahn eingezogen und zwischen dieser und der gewickelten Rolle eingeschlossen wird.In these known airlift devices for double carrier roller rollers, it is important to achieve a gap that is as uniform as possible between the surface of the roller that has already been wound and the carrier roller that is wrapped by the supplied web, because otherwise the pressure relief fluid from the one to be wrapped Web is drawn in and enclosed between this and the wound roll.
Die Erfindung hat erkannt, daß dieser Spalt nur dann gleich¬ mäßig erhalten werden kann, wenn die zu wickelnde Bahn hin¬ reichend porös ist, um die eingezogene Druckluft durchtreten zu lassen. In den meisten Fällen wirken sich Unregelmäßig¬ keiten in der Oberfläche der bereits gewickelten Rolle ent¬ lang der Berührungslinie zu der umschlungenen Tragwalze äußerst negativ auf die Menge der miteingezogenen Druckent¬ lastungsluft aus. Bei der erfindungsgemäßen Kombination führt die Nachgiebigkeit der Ummantelung der von der zuge¬ führten Bahn umschlungenen Tragwalze dazu, daß sich die Wal¬ zenoberfläche entlang der Berührungslinie mit der bereits gewickelten Rolle an die Welligkeit der Rolle in dieser Be¬ rührungslinie anpaßt. Hierdurch werden mögliche Lufteinzugs¬ spalte zwischen der eingezogenen Bahn und der gewickelten Rolle minimiert und damit die eingezogene Luft auf ein ver¬ trägliches 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 um¬ schlungene (zweite) Tragwalze eine harte, anstelle einer nachgiebigen, Ummantelung aufweist.The invention has recognized that this gap can only be obtained uniformly if the web to be wound is sufficiently porous to allow the compressed air to pass through. In most cases, irregularities in the surface of the roll that has already been wound along the line of contact with the wrapped support roller have an extremely negative effect on the amount of pressure relief air drawn in. In the combination according to the invention, the resilience of the sheathing of the support roller, which is wrapped by the supplied web, means that the roller surface adapts along the line of contact with the already wound roll to the undulation of the roll in this contact line. In this way, possible air intake gaps between the drawn web and the wound one Roll minimized and thus the intake air reduced to a tolerable amount. It goes without saying that the combination according to the invention of an airlift with a resilient sheathing of the wrapped support roller can also be used very advantageously if the non-wrapped (second) support roller has a hard sheath instead of a resilient one.
Die vorgenannten, erfindungsgemäß zu verwendenden Bauteile unterliegen in ihrer Größe, Formgestal ung, Material auswahl und technischen Konzeption keinen besonderen Ausnahmebedin¬ gungen, so daß die in dem jeweiligen Anwendungsgebiet be¬ kannten Auswahlkriterien uneingeschränkt Anwendung finden können .The aforementioned components to be used according to the invention are not subject to any special exceptional conditions in terms of their size, shape, material selection and technical conception, so that the selection criteria known in the respective field of application can be used without restriction.
Weitere Einzelheiten, Merkmale und Vorteile des Gegenstands der Erfindung ergeen sich aus der nachfolgenden Beschreibung der zugehörigen Zeichnung, in der - beispielhaft - eine be¬ vorzugte Ausführungsform einer erfindungsgemäßen Vorrichtung dargestellt ist .Further details, features and advantages of the object of the invention emerge from the following description of the associated drawing, in which - by way of example - a preferred embodiment of a device according to the invention is shown.

Bei der Ausführungsform gemäß Fig. 1 sind zwei im Durchmes¬ ser gleiche angetriebene Tragwalzen TW1 und TW2 vorgesehen, die beide eine elastisch verformbare Ummantelung Ml, M2 auf¬ weisen, wobei die Ummantelung Ml den relativ "weicheren" und die Ummantelung M2 den relativ "härteren" Belag bildet. Die zugeführte Papierbahπ PB umschlingt die erste Tragwalze TW1 etwa 180° und wird zu der Rolle R mit dem Rollengewicht G gewickelt. Für den Start jedes Wickel Vorganges kann die Ge¬ wichtsbelastung auf die beiden Tragwalzen durch eine Be¬ lastungswalze, wie an sich bekannt, künstlich erhöht werden (GBLW) . Die durch das Rollengewicht auf die beiden Tragwal¬ zen ausgeübte Normalbelastung Nl und N2 ist bei diesem Aus¬ führungsbeispiel gleich groß. Die dynamische Belastung der umschlungenen Walze TW1 und damit die Gesamtbelastung dieser Walze ist allerdings höher als die der Walze TW2.Fig shows a support roller according to the invention with a partially wound roll in a side view (all figures highly schematic). In the embodiment according to FIG. 1, two drive rollers TW1 and TW2 of the same diameter are provided, both of which have an elastically deformable casing M1, M2, the casing M1 being the relatively "softer" and the casing M2 being the relatively " forms harder "base. The supplied paper web PB wraps around the first support roller TW1 approximately 180 ° and is wound into the roll R with the roll weight G. For the start of each winding process, the weight load on the two support rollers can be artificially increased by a loading roller, as is known per se (GBLW). The normal load N1 and N2 exerted by the roller weight on the two support rollers is the same in this exemplary embodiment. However, the dynamic load on the wrapped roller TW1 and thus the total load on this roller is higher than that of the roller TW2.
Ein als AL bezeichnetes Gehäuse eines an sich bekannten Air¬ liftes ist von unten im wesentlichen randdichtend in den unteren Zwickelbereich zwischen den beiden Tragwalzen einge¬ führt. Durch den achsparallelen Austrittsspalt kann Druck¬ luft, die dem Airlif gehäuse in nicht dargestellter Weise zugeführt wird, durch den Abstandsspalt zwischen den beiden Tragwalzen in den darüber liegenden, oben von der Rolle R abgedichteten Raum als Gewichtentlastungsdruckluft einströ¬ men, wobei die Stirnseiten dieses Druckentlastungsraumes DR in bekannter Weise abgedichtet sind.A housing, referred to as AL, of an air lift known per se is inserted from below essentially edge-sealingly into the lower gusset area between the two support rollers. Through the axially parallel outlet gap, compressed air, which is fed to the airlift housing in a manner not shown, can flow through the spacing gap between the two support rollers into the space above it, which is sealed off by the roller R, 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 umschlun¬ genen Tragwalze TW1 größer als der Durchmesser der Tragwalze TW2 ist und die Achse der letzteren höher als die der erste- ren gelegen ist, wobei die Belastungswalze mit einem Winkel zur Vertikalen wirksam wird. Durch diese Anordnung ist die Normalbelastung Nl der Tragwalze TWl spürbar größer als die Normalbelastung N2 der Tragwalze TW2. Bei dieser besonders bevorzugten Ausführungsform ist die Oberfläche der nicht um¬ schlungenen Tragwalze TW2 mit einem ihren Reibwert erhöhen¬ den Belag RB versehen. Ein Airlift ist lediglich als Option und daher gestrichelt dargestellt.The embodiment according to FIG. 2 differs from that according to FIG. 1 inter alia in that the diameter of the wrapped support roller TW1 is larger than the diameter of the support roller TW2 and the axis of the latter is higher than that of the former, whereby the load roller is effective at an angle to the vertical. With this arrangement the Normal load Nl of the support roller TWl noticeably greater than the normal load N2 of the support roller TW2. In this particularly preferred embodiment, the surface of the non-wrapped support roller TW2 is provided with a coating RB which increases its coefficient of friction. An airlift is only an option and is therefore shown in dashed lines.
Die Darstellung in Fig. 3 verdeutlicht, wie die stark über¬ trieben dargestellte Welligkeit der gewickelten Rolle R von dem elastisch verformbaren Mantel Ml der Tragwalze TWl nach¬ gebildet und Lufteinzugsspalte somit minimiert oder unter¬ drückt werden. The illustration in FIG. 3 illustrates how the strongly exaggerated waviness of the wound roll R is simulated by the elastically deformable jacket M1 of the support roller TW1 and thus air intake gaps are minimized or suppressed.
