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.

Wj.ckelmaschine Wj.ckelmaschine
Die Erfindung betrifft eine Wickelmaschine zum Aufwickeln von, gegebenenfalls längsgeteilten, Bahnen, vorzugsweise von Papierbahnen, mit den Merkmalen des Oberbegriffs des An¬ spruchs 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 eine möglichst gleichmäßige Wickelstruktur zu erreichen und Wik- kelfehler 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 AI) .In order to achieve the most uniform winding structure possible and to minimize winding errors in the case of rolls which are becoming ever heavier to wind, it is known to generate a gas overpressure in the space delimited by the two support rollers and the partly produced roll and a lower seal and end walls. which increasingly compensates for the increase in weight of the roll - as the diameter progresses (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 AI).
Wie besonders deutlich aus der DE 41 10 047 AI, welche durch Bezugnahme in die Offenbarung vorliegender Erfindung hiermit einbezogen wird, hervorgeht, ist es bei diesen pneumatischen Unterstützungseinrichtungen erforderlich, sowohl den ober¬ halb des geringsten Abstandes der Tragwalzen gelegenen Zwickelraum als auch den darunter gelegenen Zwickelraum unter Bildung eines mit z. B. Druckluft beaufschlagten Wind¬ kastens abzudichten. Zur Abdichtung des unteren Zwickelbe¬ reiches weist der Windkasten kreissegmentförmige Seitenwand- bereiche auf, die dem äußeren Querschnitt der beiden Trag¬ walzen derart formangepaßt sind, daß zwischen der äußeren Windkastenoberfläche und einem Kreisbogenstück der Tragwal¬ zen ein möglichst geringer gleichmäßiger Spalt verbleibt. Durch einen dieser beiden Spalte ist vorzugsweise die auf¬ zuwickelnde Bahn geführt. Zwar sind die beiden Tragwalzen stationär angeordnet, doch stellt die große Länge der Trag- walzen, die 8 bzw. 10 m überschreiten kann, hohe Anforderun¬ gen an die exakte Einstellung des möglichst kleinen Ab- Standsspaltes zwischen den Tragwalzen und den parallel ver¬ laufenden Seitenwandteilen des Windkastens dar. Da beim Rollenwechsel bzw. Neueinfädeln einer zu wickelnden Bahn der Abstandsspalt zwischen umschlungener Tragwalze und Windka- sten zu gering ist, ist es gemäß DE 41 10 047 AI vorgesehen, den Windkasten an einem um die umschlungene Tragwalze her¬ umgeführten Armmechanismus nach unten fortzuschwenken. Die Bewegung des gesamten Windkastens stellt erhebliche Anforde¬ rungen an die Positionierung des Windkastens in die Arbeits- position, in der einerseits zu große, d. h. hohen Druckluft¬ verbrauch bewirkende Luftspalte und andererseits jeglicher Berührungskontakt zwischen dem Windkasten und der Tragwalze zu vermeiden sind, dar.As can be seen particularly clearly from DE 41 10 047 AI, which is hereby incorporated by reference into the disclosure of the present invention, it is necessary with these pneumatic support devices both the gusset space located above the smallest distance between the support rollers and the gusset space below Gusset room forming a with z. B. to seal compressed air to the wind box. To seal the lower gusset area, the wind box has side wall areas in the form of segments of a circle, which are adapted in shape to the outer cross section of the two support rollers in such a way that the smallest possible uniform gap remains between the outer wind box surface and a circular arc piece of the support rollers. The web to be wound is preferably passed through one of these two gaps. Although the two support rollers are arranged stationary, the great length of the support rollers, which can exceed 8 or 10 m, places high demands on the exact setting of the smallest possible Stand gap between the support rollers and the parallel side wall parts of the wind box. Since the gap between the looped support roller and wind box is too small when changing rolls or re-threading a web to be wound, it is provided according to DE 41 10 047 AI, the wind box to be pivoted downward on an arm mechanism which is guided around the wrapped support roller. The movement of the wind box as a whole places considerable demands on the positioning of the wind box in the working position, in which on the one hand excessive air gaps, ie high compressed air consumption, and on the other hand any contact between the wind box and the support roller are to be avoided.
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 Wik- keldurchmesser möglich. Außerdem erfordert es die Schwenk¬ barkeit des oberen und des unteren Teils des Windkastens, die Teilungsebene an die engste Stelle zwischen den Tragwal- zen zu legen, was die Abdichtprobleme weiter vergrößert.Sealing of the upper gusset space is only required at the front ends, but the problem that has to be overcome here is that the sealing surfaces available are relatively small, which makes contact-less sealing with less pressure loss possible. The sealing surfaces provided for the sealing task can only be brought into position when the winding to be produced has reached such a large diameter that the sealing surfaces can be pivoted between the winding tube guide and one of the support rollers. Because of the considerable width of the upper gusset space in the case of large end winding diameters, this is only possible from a relatively large winding diameter. In addition, the pivotability of the upper and lower part of the wind box requires that the parting plane be placed at the narrowest point between the support rollers, which further increases the sealing problems.
Davon ausgehend ist es Ziel der Erfindung, die Abdichtpro¬ bleme bei gattungsgemäßen Wickelmaschinen zu verringern.Proceeding from this, the aim of the invention is to reduce the sealing problems in winding machines of the generic type.
Ein weiteres Ziel der Erfindung besteht darin, die Druck¬ entlastung 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 the pressure of the roll to be produced from just one To enable particularly small winding diameter and thus to improve the winding structure.
Ein anderes Ziel der Erfindung besteht darin, die Verbes- serung der Wickelstruktur durch Kombination von Tragwalzen mit nachgiebiger Oberfläche, insbesondere bei unterschiedli¬ cher Nachgiebigkeit der Tragwalzenoberflächen und Anwendung des Druckentlastungsprinzips (Airlift-Prinzips) zu erzielen.Another object of the invention is to improve the winding structure by combining support rollers with a resilient surface, in particular with different resilience of the support roller surfaces and applying the pressure relief principle (airlift principle).
Schließlich besteht ein weiteres Ziel der Erfindung darin, das Einfädeln der zu wickelnden Bahn zwischen die Tragwalzen in die Wickelposition bei gattungsgemäßen Wickelmaschinen zu automatisieren.Finally, another object of the invention is to automate the threading of the web to be wound between the support rollers into the winding position in the case of generic winding machines.
Zur Lösung des angestrebten Zieles wird eine Wickelmaschine mit den Merkmalen des Anspruchs 1 vorgeschlagen.To achieve the desired goal, a winding machine with the features of claim 1 is proposed.
Durch die Merkmale des Anspruchs 2, insbesondere in Kombina¬ tion mit den Merkmalen des Anspruchs 3, wird das Einfädeln, insbesondere das automatische Einfädeln der zu wickelnden Bahn zwischen den Tragwalzen in die Wickelstartposition erleichtert.The features of claim 2, in particular in combination with the features of claim 3, facilitate the threading, in particular the automatic threading of the web to be wound between the support rollers into the winding start position.
Durch die Merkmale des Anspruchs 4, die auch unabhängig von der Anwendung der kennzeichnenden Merkmale des Anspruchs 1 bei gattungsgemäßen Wickelmaschinen, und zwar auch solchen, bei denen die zu wickelnde Bahn nicht zwischen den Tragwal¬ zen hindurchgeführt wird, vorteilhaft einsetzbar sind, ist es möglich, trotz guter Abdichtleistung den Schwenkradius der Dichtflächen für den oberen Zwickelbereich erheblich geringer als bekannt zu gestalten.The features of claim 4, which can also be used advantageously regardless of the application of the characterizing features of claim 1 in generic winding machines, including those in which the web to be wound is not passed between the support rollers, can be used advantageously to make the swivel radius of the sealing surfaces for the upper gusset area considerably smaller than known, despite good sealing performance.
Dadurch, daß die Abdichtmittel des unteren Zwickelbereiches aufgrund der Schwenkbarkeit der einen Seitenwand des Windka- stens ortsfest in Position zwischen den beiden Tragwalzen verbleiben kann und - nach Anspruch 5 - vorzugsweise auch verbleibt, wird es erstmals möglich, die horizontale Tei¬ lungsstelle zwischen den Abdichtmitteln für den unteren und oberen Zwickelbereich deutlich oberhalb der Engstelle zwi¬ schen den beiden Tragwalzen anzuordnen und damit die Abdich- tungsmöglichkeiten und die Positionierexaktheit der Seiten¬ wände des Windkastens deutlich zu verbessern. Diese Möglich¬ keit wird durch das Merkmal des Anspruchs 6 und/oder 7 noch weiter verbessert.Characterized in that the sealing means of the lower gusset region can remain stationary in position between the two support rollers due to the pivotability of the one side wall of the wind box and - according to claim 5 - preferably also remains, it becomes possible for the first time to arrange the horizontal dividing point between the sealing means for the lower and upper gusset area clearly above the narrow point between the two support rollers and thus to significantly improve the sealing options and the positioning accuracy of the side walls of the wind box . This possibility is further improved by the feature of claims 6 and / or 7.
Die vorgenannten sowie die beanspruchten und in den Ausfüh- rungsbeispielen beschriebenen, erfindungsgemäß zu verwenden¬ den Bauteile unterliegen in ihrer Größe, Formgestaltung, Materialauswahl und technischen Konzeptionen keinen besonde¬ ren Ausnahmebedingungen, so daß die in dem jeweiligen Anwen- dungsgebiet bekannten Auswahlkriterien uneingeschränkt An¬ wendung finden können.The size, shape, material selection and technical concepts of the above-mentioned and the claimed components described in the exemplary embodiments to be used according to the invention are not subject to any special exceptions, so that the selection criteria known in the respective area of application are unrestrictedly applicable can find application.

Wie aus Fig. 1 ersichtlich, sind zwei achsparallele Tragwal¬ zen TWl und TW2 mit einem konstanten minimalen Abstandsspalt G ihrer radialen Mantelflächen Ml und M2 drehbar gelagert angeordnet. Zumindest eine der Tragwalzen ist antreibbar. Der Mantel Ml, der in Bahnlaufrichtung erste Tragwalze TWl ist stärker elastisch verformbar als der Mantel M2, der in Bahnlaufrichtung zweite Tragwalze TW2. In der Zeichnung weisen beide Tragwalzen denselben Durchmesser auf und befin¬ den sich auf demselben Höhenniveau, doch können die Durch- messer und Höhenniveaus auch unterschiedlich sein. Insbeson¬ dere weist die erste Tragwalze den größeren Durchmesser und die niedrigere Achsposition auf. Diejenige der beiden Trag¬ walzen, deren aus statischer und dynamischer Belastung beim Wickeln resultierende Gesamtbelastung die größere von den beiden Tragwalzen ist, weist den von beiden Tragwalzen stär¬ ker elastisch verformbaren Mantel auf.As can be seen from FIG. 1, two axially parallel support rollers TW1 and TW2 with a constant minimum spacing gap G of their radial lateral surfaces M1 and M2 are rotatably arranged. At least one of the support rollers can be driven. The jacket M1, the first carrier roller TW1 in the web running direction, is more elastically deformable than the jacket M2, the second carrier roller TW2 in the web running direction. In the drawing, both support rollers have the same diameter and are at the same height level, but the diameter and height levels can also be different. In particular, the first support roller has the larger diameter and the lower axis position. That of the two support rollers, the total load resulting from static and dynamic loading during winding is the greater of the two support rollers, has the jacket which is more elastically deformable by both support rollers.
Die auf den beiden Tragwalzen rotierenden Wickel R bzw. Teilwickel R', R'', R''', ..., welche durch hier nicht dar- gestellte Längsteilung der zu wickelnden Bahn, wie einer Pa¬ pierbahn PB, entstanden sind, dichten den Zwickelraum zwi¬ schen beiden Tragwalzen, der oberhalb des Abstandsspaltes G sich befindet (oberer Zwickelbereich), nach oben hin ab.The coils R or partial coils R ', R' ', R' '', ... rotating on the two support rollers, which are caused by the longitudinal division of the web to be wound, not shown here, such as a paper web PB, seal the gusset space between the two support rollers, which is located above the spacing gap G (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 Zwickelbe¬ reich 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 Wickel¬ achse sich erstreckende Schwenkachse 15 um etwa 90° fort¬ schwenkbar ist, so daß der Schwenkradius SR der Dichtflächen 14 bei vom Wickel R fortgeschwenkter Teilfläche 14A im Ver¬ gleich zur an dem Wickel R anliegenden Teilfläche 14A ver¬ ringert wird. In Fig. 4 ist die Dichtposition mit durchgezo¬ genen und die Fortschwenkposition mit strichpunktierten Linien dargestellt. Zum Fortschwenken dient eine Kolben- /Zylindereinheit 22. Am unteren Ende des nicht fortschwenk¬ baren, lediglich um die Achse TWA2 drehbaren Teils der Dichtfläche 14 befindet sich eine etwa parallel zu den Trag¬ walzenachsen 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. 3 ergibt (durchgezogene und strichpunktierte Position der Abdichtflächen 14 und Abdichtplatte 19), wird damit eine Anpassung an die maximale und minimale Breite des herzustel¬ lenden Wickels, an dessen Stirnflächen RE die Dichtflächen 14 anliegen, ermöglicht.Frontal sealing surfaces 14 for the upper gusset area are pivotally mounted about the axis TWA2 of the second support roller TW2 by means of a piston / cylinder unit 20 and a two-armed lever 21, so that they can be pivoted into the working position shown and out of it for the first winding phase are. The radially outermost region of the sealing surface 14 with respect to the pivot axis TWA2 is as Partial surface 14A designed, which is pivotable from the sealing position shown about a substantially perpendicular to the winding axis 15 pivot axis 15 by approximately 90 °, so that the pivoting radius SR of the sealing surfaces 14 in comparison with the part R 14 pivoted away from the winding is reduced to the partial surface 14A lying against the winding R. 4 shows the sealing position with solid lines and the pivoting position with dash-dotted lines. A piston / cylinder unit 22 is used for pivoting. At the lower end of the non-pivotable part of the sealing surface 14, which can only be rotated about the axis TWA2, there is a sealing plate 19 which extends approximately parallel to the support roller axes and which extends axially outward from extends the sealing surface 14 and, in cooperation with a sealing table 18 of a wind box 16, which is yet to be explained, allows the wind box to be sealed between the upper and lower gusset areas with different winding widths. As can be seen particularly clearly from FIG. 3 (solid and dash-dotted position of the sealing surfaces 14 and sealing plate 19), this enables adaptation to the maximum and minimum width of the roll to be produced, on the end faces RE of which the sealing surfaces 14 rest.
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 AI grundsätzlich bereits bekannt sind.Guides 23 and an adjusting means 24, which are provided on the two-armed lever 21 and are fundamentally already known from DE 41 10 047 AI, are used to adapt to the winding widths and to set a sealing gap between the sealing surfaces 14 and the end faces RE that is as contactless as possible.
Der untere Zwickelbereich zwischen den beiden Tragwalzen TWl 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 Dichtflä- chen 14 ein allseits geschlossener Druckraum DR entsteht, welcher am unteren Ende des Windkastens 16 über mehrere entlang der Tragwalzenbreite verteilt angeordnete Rohrstut¬ zen 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 sealed by a wind box 16 which is arranged in a stationary manner and is open at the top, so that in interaction between the latter, the two support rollers, the coil and the sealing surfaces. Chen 14 creates a pressure chamber DR which is closed on all sides and which can be pressurized with compressed air (airlift fluid) at the lower end of the wind box 16 via a plurality of pipe stubs 25 arranged along the width of the support rollers. The wind box 16 is supported by stationary supports 26.
Der Windkasten 16 besteht im wesentlichen aus einer Boden¬ platte 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 ILA, welche sich etwa parallel zu den Tragwalzenachsen erstreckt, schwenkbar ist. Diese Sei¬ tenwand 11 ist an die von der aufzuwickelnden Bahn PB um¬ schlungene Tragwalze TWl unter Freilassung eines Bahndurch- trittsspaltes GP für den Wickelvorgang dichtend heran- schwenkbar (Fig. 2, gestrichelter Linienzug) und für den Einfädelvorgang der Bahn PB von der umschlungenen Tragwalze TWl fortschwenkbar (Fig. 1, durchgezogener Linienzug). Die in Bahnlaufrichtung sich erstreckende Länge des Bahndurch- trittsspaltes ergibt sich aus derjenigen Schenkellänge der schwenkbaren Seitenwand 11, welche an die äußere Oberfläche der ersten Tragwalze TWl angepaßt gebogen ist. Zum Ver¬ schwenken der Seitenwand 11 dient eine am Windkasten 16 gelagerte Kolben-/Zylindereinheit 29. Die Verwindungsstei- figkeit 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 druck¬ dicht verschlossen. Die wünschenswerte Stabilität des Ab- dichttisches 18 an den oberen Enden 17A der Stirnwände 17 des Windkastens 16 wird durch Diagonalstreben 31 erreicht. Über die Maschinenbreite sich erstreckende Leitflächen 12 verlängern den von der schwenkbaren Seitenwand 11 gebildeten Bahndurchtrittsspalt GP unter Spaltverbreiterung in Richtung auf die einlaufende Bahn PB hin. In den Leitflächen 12 an¬ geordnete Druckgasdüsen 13 erleichtern das Einfädeln der zu wickelnden Bahn und deren Anlegen an die umschlungene Trag¬ walze TWl. The wind box 16 consists essentially of a base plate 27, which is pierced by the pipe socket 25, of a stationary, essentially circular arc-shaped side wall 28, which is adapted to the shape of the second support roller TW2 while leaving a minimal sealing gap and is rigidly attached to the wind box 16 , and from a side wall 11 which extends essentially over the entire maximum web width of the roll to be produced and which is pivotable about a pivot axis ILA, which extends approximately parallel to the support roller axes. This side wall 11 can be swiveled sealingly against the support roller TW1 wrapped by the web PB to be wound, leaving a web passage gap GP open for the winding process (FIG. 2, dashed line) and for the threading process of the web PB from the looped one Carrier roller TWl can be swiveled (Fig. 1, solid line). The length of the web passage gap extending in the web running direction results from that leg length of the pivotable side wall 11 which is bent to match the outer surface of the first support roller TW1. A piston / cylinder unit 29 mounted on the wind box 16 serves to pivot the side wall 11. The torsional rigidity of the wind box 16 and additional support of the pipe socket is achieved by diagonal struts or plates 30, which are connected to the base plate 27 and the stationary side wall 28 connected, in particular welded. On the face side, the wind box 16 is closed pressure-tight by end walls 17. The desirable stability of the sealing table 18 at the upper ends 17A of the end walls 17 of the wind box 16 is achieved by diagonal struts 31. Guiding surfaces 12 extending over the machine width extend the web passage gap GP formed by the pivotable side wall 11, widening the gap in the direction of the incoming web PB. Compressed gas nozzles 13 arranged in the guide surfaces 12 facilitate threading the web to be wound and placing it on the wrapped support roller TW1.
