Abstract

The machine is particularly for paper strip (PB), having two rollers (TW1,TW2) supporting the coil to be formed (R). The casings (M1,M2) of the rollers distort, preferably to different degrees. During the coiling operation, the strip passes through the gap (G) between the rollers and part-way round one of them. The chamber (DR) between the rollers and the partly-farmed coil is sealed at the ends and underside and supplied with compressed air to relieve the weight of the coil. The seal below the gap has a sidewall (11) extending for the maximum overall width of the coil to be formed, and hinging on an axis (11A) parallel to those of the rollers. It swings between a position forming a seal against the roller round which the strip passes, while leaving a gap (GP) through which the strip passes during coiling, and one clear of the roller to allow the strip to be threaded into place. The gap (GP) an be extended by guide faces clear of the roller in the radial direction and towards the incoming strip.

Description

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

Um bei immer schwerer werdenden zu wickelnden Rollen eine möglichst gleichmäßige Wickelstruktur zu erreichen und Wikkelfehler zu minimieren, ist es bekannt, in dem von den beiden Tragwalzen und dem zum Teil hergestellten Wickel und einer unteren Abdichtung sowie Stirnwänden begrenzten Raum einen Gasüberdruck zu erzeugen, der den Gewichtszuwachs des Wickels zunehmend - bei fortschreitendem Durchmesser völlig - kompensiert (DE-GM 92 01 791, DE-PS 1 047 001, DE-PS 1 111 496, US-PS 3 497 151, US-PS 3 346 209, WO 92/03366, DE 41 10 047 A1).In order to get a roll with increasingly difficult rolls to be wound to achieve as uniform a winding structure as possible and winding errors to minimize, it is known in which of the two support rollers and the partially manufactured roll and a lower seal and end walls limited space generate a gas overpressure that the weight gain of the Winding increasingly - with increasing diameter completely - compensated (DE-GM 92 01 791, DE-PS 1 047 001, DE-PS 1 111 496, U.S. Patent 3,497,151, U.S. Patent 3,346,209, WO 92/03366, DE 41 10 047 A1).

Wie besonders deutlich aus der DE 41 10 047 A1, welche durch Bezugnahme in die Offenbarung vorliegender Erfindung hiermit einbezogen wird, hervorgeht, ist es bei diesen pneumatischen Unterstützungseinrichtungen erforderlich, sowohl den oberhalb des geringsten Abstandes der Tragwalzen gelegenen Zwickel raum als auch den darunter gelegenen Zwickelraum unter Bildung eines mit z. B. Druckluft beaufschlagten Windkastens abzudichten.As is particularly clear from DE 41 10 047 A1, which by Reference is hereby made to the disclosure of the present invention is included, it is with these pneumatic Support facilities required, both the above the smallest distance between the support rollers Gusset room as well as the gusset room below forming a with z. B. Compressed air loaded wind box to seal.

Die Abdichtung des oberen Zwickelraumes ist zwar lediglich an dessen Stirnenden erforderlich, doch ist hier das Problem zu bewältigen, daß die zur Verfügung stehenden Dichtflächen relativ kleinflächig sind, was eine berührungslose aber möglichst druckverlustarme Abdichtung erschwert. Die für die Abdichtungsaufgabe vorgesehenen Dichtflächen können erst dann in Position gebracht werden, wenn der zu erzeugende Wickel einen so großen Durchmesser erreicht hat, daß die Dichtflächen zwischen der Wickelhülsenführung und einer der Tragwalzen hindurchgeschwenkt werden können. Dies ist wegen der bei großen Wickel-Enddurchmessern beträchtlichen Breite des oberen Zwickelraumes erst ab einem relativ großen Wikkeldurchmesser möglich. Außerdem erfordert es die Schwenkbarkeit des oberen und des unteren Teils des Windkastens, die Teilungsebene an die engste Stelle zwischen den Tragwalzen zu legen, was die Abdichtprobleme weiter vergrößert.The sealing of the upper gusset is only required at the ends, but here is the problem to cope with the available sealing surfaces are relatively small, which is a non-contact sealing that is as low as possible difficult. The for the The sealing surfaces provided for the sealing task can only then be positioned when the one to be generated Has reached such a large diameter that the Sealing surfaces between the winding tube guide and one of the Carrier rollers can be pivoted through. This is because the considerable width for large winding diameters of the upper gusset space only from a relatively large winding diameter possible. It also requires swiveling the upper and lower part of the wind box, the division level to the narrowest point between the support rollers to put, which further increases the sealing problems.

Davon ausgehend ist es Ziel der Erfindung, die Abdichtprobleme bei gattungsgemäßen Wickelmaschinen zu verringern.Based on this, the aim of the invention is to address the sealing problems to reduce with generic winding machines.

Ein weiteres Ziel der Erfindung besteht darin, die Druckentlastung des herzustellenden Wickels bereits ab einem besonders geringen Wickeldurchmesser zu ermöglichen und damit die Wickelstruktur zu verbessern.Another object of the invention is to relieve pressure of the roll to be produced from one to enable particularly small winding diameters and to improve the winding structure.

Ein anderes Ziel der Erfindung besteht darin, die Verbesserung der Wickelstruktur durch Kombination von Tragwalzen mit nachgiebiger Oberfläche, insbesondere bei unterschiedlicher Nachgiebigkeit der Tragwalzenoberflächen und Anwendung des Druckentlastungsprinzips (Airlift-Prinzips) zu erzielen.Another object of the invention is improvement the winding structure by combining carrier rollers with a flexible surface, especially with different ones Resilience of the roller surface and application to achieve the pressure relief principle (airlift principle).

Zur Lösung des angestrebten Zieles wird eine Wickelmaschine mit den Merkmalen des Anspruchs 1 vorgeschlagen.A winding machine is used to achieve the desired goal proposed with the features of claim 1.

Durch die Merkmale des Anspruchs 1, ist es möglich, trotz guter Abdichtleistung den Schwenkradius der Dichtflächen für den oberen Zwickelbereich erheblich geringer als bekannt zu gestalten.Due to the features of claim 1, it is possible despite good sealing performance the swivel radius of the sealing surfaces for the upper gusset area significantly less than known shape.

Dadurch, daß die Abdichtmittel des unteren Zwickelbereiches aufgrund der Schwenkbarkeit der einen Seitenwand des Windkastens, insbesondere ortsfest, in Position zwischen den beiden Tragwalzen verbleiben können, wird es erstmals möglich, die horizontale Teilungsstelle zwischen den Abdichtmitteln für den unteren und oberen Zwickelbereich deutlich oberhalb der Engstelle zwischen den beiden Tragwalzen anzuordnen und damit die Abdichtungsmöglichkeiten und die Positionierexaktheit der Seitenwände des Windkastens deutlich zu verbessern. Diese Möglichkeit wird durch das Merkmal des Anspruchs 3 noch weiter verbessert.The fact that the sealing means of the lower gusset area due to the pivotability of one side wall of the wind box, especially stationary, in position between the two Carrier rollers can remain, it becomes possible for the first time the horizontal division point between the sealing means for the lower and upper gusset area clearly above to arrange the constriction between the two support rollers and thus the sealing options and positioning accuracy to significantly improve the side walls of the wind box. This possibility is through the feature of claim 3 improved even further.

Die vorgenannten sowie die beanspruchten und in den Ausführungsbeispielen beschriebenen, erfindungsgemäß zu verwendenden Bauteile unterliegen in ihrer Größe, Formgestaltung, Materialauswahl und technischen Konzeptionen keinen besonderen Ausnahmebedingungen, so daß die in dem jeweiligen Anwendungsgebiet bekannten Auswahlkriterien uneingeschränkt Anwendung finden können.The aforementioned and the claimed and in the exemplary embodiments described, to be used according to the invention Components are subject to their size, shape, Material selection and technical conceptions are not special Exceptions, so that in the respective application known selection criteria without restrictions can find.

Weitere Einzelheiten, Merkmale und Vorteile des Gegenstandes der Erfindung ergeben sich aus der nachfolgenden Beschreibung der zugehörigen Zeichnung, in der - beispielhaft - bevorzugte Ausführungsformen erfindungsgemäßer Wickelmaschinen dargestellt sind. In der Zeichnung zeigen

    • Further details, features and advantages of the subject matter of the invention result from the following description of the associated drawing, in which - by way of example - preferred embodiments of winding machines according to the invention are shown. Show in the drawing
  • Figure 1 of a generic winding machine the parts essential to the invention in front view in a working position during the compressed air-assisted winding.

    • Wie aus Fig. 1 ersichtlich, sind zwei achsparallele Tragwalzen TW1 und TW2 mit einem konstanten minimalen Abstands spalt G ihrer radialen Mantelflächen M1 und M2 drehbar gelagert angeordnet. Zumindest eine der Tragwalzen ist antreibbar. Der Mantel M1, der in Bahnlaufrichtung erste Tragwalze TW1 ist stärker elastisch verformbar als der Mantel M2, der in Bahnlaufrichtung zweite Tragwalze TW2. In der Zeichnung weisen beide Tragwalzen denselben Durchmesser auf und befinden sich auf demselben Höhenniveau, doch können die Durchmesser und Höhenniveaus auch unterschiedlich sein. Insbesondere weist die erste Tragwalze den größeren Durchmesser und die niedrigere Achsposition auf. Diejenige der beiden Tragwalzen, deren aus statischer und dynamischer Belastung beim Wickeln resultierende Gesamtbelastung die größere von den beiden Tragwalzen ist, weist den von beiden Tragwalzen stärker elastisch verformbaren Mantel auf.As can be seen from Fig. 1, there are two axially parallel support rollers TW1 and TW2 with a constant minimum gap G their radial lateral surfaces M1 and M2 rotatably mounted arranged. At least one of the support rollers can be driven. The jacket M1, the first support roller TW1 in the web running direction is more elastically deformable than the jacket M2, which in Web direction of the second support roller TW2. In the drawing both carrier rollers have the same diameter and are themselves at the same level, but the diameters and height levels may also be different. Especially the first support roller has the larger diameter and the lower axis position. That of the two support rollers, whose from static and dynamic load when Resulting total load the larger of the coils is two support rollers, has that of both support rollers stronger elastically deformable jacket.

    Die auf den beiden Tragwalzen rotierenden Wickel R bzw. Teilwickel R', R'', R''', welche durch hier nicht dargestellte Längsteilung der zu wickelnden Bahn, wie einer Papierbahn PB, entstanden sind, dichten den Zwickelraum zwischen beiden Tragwalzen, der oberhalb des Abstandsspaltes G sich befindet (oberer Zwickelbereich), nach oben hin ab.The coils R or Partial winding R ', R' ', R' '', which by not shown here Longitudinal division of the web to be wound, such as a paper web PB, are created, seal the gusset space between two support rollers, the above the gap G is located (upper gusset area), towards the top.

    Um die Achse TWA2 der zweite Tragwalze TW2 mittels einer Kolben-/Zylindereinheit 20 und eines zweiarmigen Hebels 21 sind stirnseitige Dichtflächen 14 für den oberen Zwickelbereich schwenkbar gelagert, so daß sie in die dargestellte Arbeitsposition hinein und für die erste Wickelphase aus ihr heraus schwenkbar sind. Der in Bezug auf die Schwenkachse TWA2 radial äußerste Bereich der Dichtfläche 14 ist als Teilfläche 14A ausgestaltet, welche aus der dargestellten Dichtposition um eine im wesentlichen senkrecht zur Wickelachse sich erstreckende Schwenkachse 15 um etwa 90° fortschwenkbar ist, so daß der Schwenkradius SR der Dichtflächen 14 bei vom Wickel R fortgeschwenkter Teilfläche 14A im Vergleich zur an dem Wickel R anliegenden Teilfläche 14A verringert wird. In Fig. 3 ist die Dichtposition mit durchgezogenen und die Fortschwenkposition mit strichpunktierten Linien dargestellt. Zum Fortschwenken dient eine Kolben/zylindereinheit 22. Am unteren Ende des nicht fortschwenkbaren, lediglich um die Achse TWA2 drehbaren Teils der Dichtfläche 14 befindet sich eine etwa parallel zu den Tragwalzenachsen sich erstreckende Abdichtplatte 19, die sich nach axial außen von der Dichtfläche 14 forterstreckt und im Zusammenwirken mit einem noch zu erläuterten Abdichttisch 18 eines Windkastens 16 das Abdichten des Windkastens zwischen dem oberen und unteren Zwickelbereich bei unterschiedlichen Wickelbreiten gestattet. Wie sich besonders deutlich aus Fig. 2 ergibt (durchgezogene und strichpunktierte Position der Abdichtflächen 14 und Abdichtplatte 19), wird damit eine Anpassung an die maximale und minimale Breite des herzustellenden Wickels, an dessen Stirnflächen RE die Dichtflächen 14 anliegen, ermöglicht.Around the axis TWA2 of the second support roller TW2 by means of a Piston / cylinder unit 20 and a two-armed lever 21 are end sealing surfaces 14 for the upper gusset area pivoted, so that it is shown in the Working position in and for the first winding phase out of it are pivotable out. The one in relation to the swivel axis TWA2 radially outermost region of the sealing surface 14 is as Partial area 14A designed, which from the illustrated Sealing position around a substantially perpendicular to the winding axis extending pivot axis 15 can be pivoted about 90 ° is so that the swivel radius SR of the sealing surfaces 14 in comparison with partial surface 14A pivoted away from the winding R. to the partial surface 14A which is in contact with the winding R. becomes. In Fig. 3, the sealing position is solid and the pivoting position with dash-dotted lines Lines shown. A piston / cylinder unit is used for swiveling 22. At the lower end of the non-swiveling, only part of the Sealing surface 14 is located approximately parallel to the support roller axes extending sealing plate 19 which extends axially outward from the sealing surface 14 and in Cooperation with a sealing table 18 to be explained a wind box 16 sealing the wind box between the upper and lower gusset area at different Wrapping widths allowed. As is particularly evident Fig. 2 results (solid and dash-dotted position the sealing surfaces 14 and sealing plate 19), is thus a Adaptation to the maximum and minimum width of the manufactured Winding, on the end faces RE the sealing surfaces 14 concerns, enables.

    Für die Anpassung an die Wickelbreiten und zur Einstellung eines möglichst berührungslosen Dichtspaltes zwischen den Dichtflächen 14 und den Stirnflächen RE dienen Führungen 23 und ein Verstellmittel 24, welche an dem zweiarmigen Hebel 21 vorgesehen und aus der DE 41 10 047 A1 grundsätzlich bereits bekannt sind.For adaptation to the winding widths and for adjustment a sealing gap between the Sealing surfaces 14 and the end surfaces RE serve guides 23 and an adjusting means 24, which on the two-armed lever 21 provided and basically from DE 41 10 047 A1 are already known.

    Der untere Zwickelbereich zwischen den beiden Tragwalzen TW1 und TW2 sowie die untere Zone des oberen Zwickelbereiches werden durch einen ortsfest angeordneten, nach oben offenen Windkasten 16 abgedichtet, so daß im Zusammenwirken zwischen diesem, den beiden Tragwalzen, dem Wickel und den Dichtflächen 14 ein allseits geschlossener Druckraum DR entsteht, welcher am unteren Ende des Windkastens 16 über mehrere entlang der Tragwalzenbreite verteilt angeordnete Rohrstutzen 25 mit Druckluft (Airliftfluid) beaufschlagbar ist. Der Windkasten 16 wird durch ortsfeste Stützen 26 getragen.The lower gusset area between the two support rollers TW1 and TW2 and the lower zone of the upper gusset area are arranged by a fixed, open top Wind box 16 sealed so that in cooperation between this, the two support rollers, the winding and the sealing surfaces 14 a pressure chamber DR is closed on all sides, which at the lower end of the wind box 16 over several Pipe sockets distributed along the width of the roller 25 can be acted upon with compressed air (airlift fluid). Of the Wind box 16 is supported by stationary supports 26.

    Der Windkasten 16 besteht im wesentlichen aus einer Bodenplatte 27, welche von den Rohrstutzen 25 durchbrochen ist, aus einer ortsfesten im wesentlichen kreisbogenförmigen Seitenwand 28, welche unter Freilassung eines minimalen Dichtspaltes an die zweite Tragwalze TW2 formangepaßt und starr an dem Windkasten 16 befestigt ist, sowie aus einer Seitenwand 11, die im wesentlichen über die gesamte maximale Bahnbreite des herzustellenden Wickels sich erstreckt und die um eine Schwenkachse 11A, welche sich etwa parallel zu den Tragwalzenachsen erstreckt, schwenkbar ist. Diese Seitenwand 11 ist an die von der aufzuwickelnden Bahn PB umschlungene Tragwalze TW1 unter Freilassung eines Bahndurchtrittsspaltes GP für den Wickelvorgang dichtend heranschwenkbar (Fig. 1, gestrichelter Linienzug) und für den Einfädelvorgang der Bahn PB von der umschlungenen Tragwalze TW1 fortschwenkbar. Die in Bahnlaufrichtung sich erstrekkende Länge des Bahndurchtrittsspaltes ergibt sich aus derjenigen Schenkellänge der schwenkbaren Seitenwand 11, welche an die äußere Oberfläche der ersten Tragwalze TW1 angepaßt gebogen ist. Zum Verschwenken der Seitenwand 11 dient eine am Windkasten 16 gelagerte Kolben-/Zylindereinheit 29. Die Verwindungssteifigkeit des Windkastens 16 und zusätzliche Abstützung der Rohrstutzen wird durch Diagonalstreben oder-platten 30 erreicht, welche mit der Bodenplatte 27 und der ortsfesten Seitenwand 28 verbunden, insbesondere verschweißt sind. Stirnseitig ist der Windkasten 16 durch Stirnwände 17 druckdicht verschlossen. Die wünschenswerte Stabilität des Abdichttisches 18 an den oberen Enden 17A der Stirnwände 17 des Windkastens 16 wird durch Diagonalstreben 31 erreicht.The wind box 16 essentially consists of a base plate 27, which is pierced by the pipe socket 25, from a stationary, essentially circular arc Side wall 28, which leaves a minimal Sealing gap adapted to the shape of the second support roller TW2 and is rigidly attached to the wind box 16, as well as from a Side wall 11, which is essentially the entire maximum Web width of the roll to be produced extends and that about a pivot axis 11A, which is approximately parallel to extends the support roller axes, is pivotable. This side wall 11 is wrapped around the web PB to be wound Carrier roller TW1 leaving a web passage gap free GP can be swiveled sealingly for the winding process (Fig. 1, dashed line) and for the Threading the web PB from the wrapped support roller TW1 swiveling. The extending in the web running direction Length of the web passage gap results from that Leg length of the pivotable side wall 11, which adapted to the outer surface of the first support roller TW1 is bent.
