The invention is characterised in that the other supporting element has a rigid carrier (4) which guides the web reel over a tubular sleeve (7, 7') which is arranged or guided rotatably about the carrier and over a carrying shoe (5, 5') which is connected to said sleeve, is hydrodynamically effective with respect thereto and is provided with a concave pressure surface (12, 12') which has a radius of curvature corresponding essentially to the largest reel (T) with the addition of the sleeve wall thickness, it being possible to adapt the carrying shoe (5, 5'), in its position, to the respective wound size (position of the circumference) of the web reel (W'). <IMAGE>

Description

Die Erfindung betrifft eine Wickelvorrichtung entsprechend dem Oberbegriff des Patentanspruchs 1. Eine solche Vorrichtung ist bekannt aus DE 32 21 929 C3. Solche sogenannte Doppel-Tragwalzen-Wickeleinrichtungen haben den Nachteil, daß wegen der hohen Linienpressung des Bahnwickels schon vor Erreichen seiner maximalen Größe es zu Störstellen oder sogar zu Bruchstellen im Wickelaufbau kommen kann. Ferner ist es auch schwierig, bei sehr großen Wickeldurchmessern den Unterstützungsdruck über die gesamte Wickellänge konstant zu halten. Bei Stützwalzenmaschinen werden die Wickel jeweils in zwei Spannzapfen geführt. Dadurch ist es möglich, einen beliebigen Teil des Rollengewichts durch Entlastungseinrichtungen aufzunehmen und entsprechend die Pressung des Wickels zu verringern. Diese Einrichtungen sind aber sehr aufwendig.The invention relates to a winding device according to the preamble of claim 1. Such a device is known from DE 32 21 929 C3. Such so-called double carrier roll winding devices have the disadvantage that, because of the high line pressure of the web winding, even before reaching its maximum size, there may be defects or even break points in the winding structure. Furthermore, it is also difficult to keep the support pressure constant over the entire length of the winding in the case of very large winding diameters. In the case of backing roll machines, the windings are each guided in two clamping pins. This makes it possible to absorb any part of the roll weight by means of relief devices and accordingly to reduce the pressure on the roll. However, these facilities are very complex.

Das Dokument DE-A-33 17457 offenbart eine Schuhpresseneinheit, deren Gegenwalze einen konstanten Durchmesser aufweist.Document DE-A-33 17457 discloses a shoe press unit, the counter roll of which has a constant diameter.

Die Aufgabe der Erfindung ist es, eine Wickelvorrichtung zu schaffen, bei der zwei Unterstützungselemente so angeordnet oder aufgebaut sind, daS der Liniendruck auf den Bahnwickel relativ gering bleibt, so daS verhältnismäßig große Durchmesser des Wickels erreichbar sind.The object of the invention is to provide a winding device in which two support elements are arranged or constructed in such a way that the line pressure on the web winding remains relatively low, so that relatively large diameters of the winding can be achieved.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des kennzeichnenden Teils des Patentanspruchs 1 gelöst.This object is achieved by the features of the characterizing part of patent claim 1.

Es sind zwar schon Preßvorrichtungen mit Walzen oder walzenähnlichen Preßelementen bekannt, bei denen das eine Preßelement eine sogenannte Schlauchwalze ist (siehe US 45 63 245). Dabei ist das eine Preßelement ein von einem Preßschuh angepreßter schlauchförmiger umlaufender Mantel, wobei Mantel und Preßschuh von einem starren, oft rohrförmig ausgebildeten Träger gehalten sind. Erfindungsgemäß ist aber erkannt worden, daS diese für Preßeinrichtungen an sich gedachte Vorrichtung auch erfindungsgemäß mit entsprechenden Abwandlungen einsetzbar ist, um den Liniendruck der Wickel zu verringern.It is true that pressing devices with rollers or roller-like pressing elements are already known, in which the one pressing element is a so-called tube roller (see US 45 63 245). The one press element is a pressed from a press shoe tubular circumferential jacket, the jacket and press shoe being held by a rigid, often tubular support. According to the invention, however, it has been recognized that this device, which is intended for pressing devices per se, can also be used according to the invention with corresponding modifications in order to reduce the line pressure of the windings.

Dabei wird vorzugsweise so vorgegangen, daS der Preßschuh jeweiligen Lage bzw. der Größe des Wickels angepaßt wird, um jeweils immer eine ausreichende Führung und Unterstützung desselben zu haben.In this case, the procedure is preferably such that the press shoe is adapted to the respective position or the size of the winding in order to always have adequate guidance and support for the same.

Dabei kann man einmal so vorgehen, daß man den Preßschuh (oder hier besser Tragschuh) entlang einem Umfangskreis verschiebt, wobei man vorzugsweise den Tragschuh fest mit einem - günstigerweise zylinderförmigen - Träger verbindet, der dann um seine Längsachse gedreht wird, um den Tragschuh in die erforderliche Stellung zu schwenken. Man kann auch den Tragschuh schwenkbar an einem zentralen Träger anordnen, welcher auch hohlzylinderförmig ausgebildet sein kann. Als Hubelemente können dann hydraulische Kolben-Zylindereinheiten dienen. Es ist auch möglich, Druckschläuche zwischen dem Träger und dem Tragschuh vorzusehen. Diese haben den Vorteil, daß sie den Tragschuh über seine ganze Länge unterstützen. Um eine Durchbiegung desselben zu verhindern, kann er dann dünner ausgebildet sein, als wenn an seinen Enden Kolbenstangen angreifen würden.One can proceed in such a way that one moves the press shoe (or better here the support shoe) along a circumferential circle, preferably connecting the support shoe firmly to a - favorably cylindrical - support, which is then rotated about its longitudinal axis, around the support shoe in the swivel required position. You can also pivotally arrange the support shoe on a central support, which can also be designed as a hollow cylinder. Hydraulic piston-cylinder units can then serve as lifting elements. It is also possible to provide pressure hoses between the carrier and the support shoe. These have the advantage that they support the carrying shoe over its entire length. In order to prevent the same from bending, it can then be made thinner than if piston rods were to attack at its ends.

Gemäß Fig. 1 ist für den flexiblen schlauchartigen Mantel 7 ein kreiszylindrischer hohler Träger 4 vorgesehen, der noch Unterstützungselemente 6 für den Mantel aufweist. Diese können auch hydrodynamisch geschmiert sein bzw. wirken, um den Mantel z.B. nicht nur während der Montage, sondern auch im Betrieb zu führen. An einer Stelle ist an dem Träger 4 ein sich über die Länge des Trägers bzw. über die Papierbahnbreite erstreckender Tragschuh 5 befestigt, der eine Lauffläche - in bezug auf den Bahnwickel (W', siehe Fig. 3) -, die hydrodynamisch geschmiert ist und konkav entsprechend dem maximalen Wickeldurchmesser (Tambour T, siehe Fig. 2) ausgebildet ist. In diesem Fall ist die Bahn W über den flexiblen Mantel geleitet. Die - insoweit starre - Tragwalze 2 für den Wickel ist angetrieben. Die Wickelhülse 9 wird hier durch eine Andruckrolle 21 an die tragenden Oberflächen gepreßt. Bei dieser Anordnung kann vorzugsweise der flexible schlauchartige Mantel 7 angetrieben sein, z.B. durch Stirnscheiben entsprechend der DE 38 05 350 C2. Es ist auch möglich, einen Reibantrieb über den Umfang des Mantels, wie es in Fig. 3 angedeutet ist, vorzusehen. Es kann aber auch die Bahn über die Tragwalze 2 geleitet werden (wie im Falle von Fig. 3).1, a circular cylindrical hollow carrier 4 is provided for the flexible tubular jacket 7, which still has support elements 6 for the jacket. These can also be hydrodynamically lubricated or act to e.g. not only during assembly, but also during operation. At one point, a support shoe 5 is attached to the support 4 and extends over the length of the support or across the width of the paper web, which has a running surface - with respect to the web winding (W ', see FIG. 3) - which is hydrodynamically lubricated and is concave in accordance with the maximum winding diameter (drum T, see Fig. 2). In this case, the web W is passed over the flexible jacket. The - so far rigid - support roller 2 for the winding is driven. The winding tube 9 is pressed here by a pressure roller 21 against the supporting surfaces. With this arrangement, the flexible tubular jacket 7 can preferably be driven, e.g. by face plates according to DE 38 05 350 C2. It is also possible to provide a friction drive over the circumference of the casing, as indicated in FIG. 3. However, the web can also be passed over the support roller 2 (as in the case of FIG. 3).

Es ist natürlich wichtig, daß der Tragschuh 5 (5' in Fig. 3) auf einem erheblich tieferen Niveau (mindestens etwa 100 mm) als die oberste Mantellinie (Mantelerzeugende) der starren Tragwalze 2 angeordnet ist, so daß der Tragschuh den weitaus größeren Anteil des Wickelgewichts trägt.It is of course important that the support shoe 5 (5 'in Fig. 3) is arranged at a considerably lower level (at least about 100 mm) than the top surface line (jacket generator) of the rigid support roller 2, so that the support shoe the far larger proportion of the winding weight.

Beim Beginn des Wickelvorganges ist nur die kleine Wickelhülse 9 vorhanden, und es setzt der Wickelvorgang ein, wobei wegen des dann noch kleinen Wickeldurchmessers der Tragschuh 5 in einer ziemlich unteren Position angeordnet ist. Mit wachsendem Wickeldurchmesser wird der Tragschuh 5 mehr und mehr nach oben geschwenkt - hier einfach durch Drehung des Tragkörpers 4 um dessen Längsachse -, so daß wie bei üblichen Doppeltragwalzen-Rollern an zwei länglichen Bereichen, die am Umfang des Wickels voneinander beabstandet sind, dieser getragen wird. Es ist natürlich so, daß der Krümmungsradius des Tragschuhes 5 den kleineren Durchmessern des Wickels nicht entspricht, so daß hier kein wesentlicher Vorteil gegenüber dem üblichen Doppeltragwalzen-Roller besteht. Sobald aber der Wickel eine Größe im Bereich seines maximalen Durchmessers hat, erhöht sich die Tragfläche, auf der sich der Wickel auf dem Tragschuh 5 abstützt, erheblich. (Es ist ja bekannt, daß selbst bei einer Walze mit harter, glatter Oberfläche sich eine Preßfläche einer Länge in Umfangsrichtung zwischen 20 und 25 mm bei großem Wickeldurchmesser und entsprechend großem Tambourgewicht ergibt.)At the beginning of the winding process, only the small winding sleeve 9 is present, and the winding process begins, the carrying shoe 5 being arranged in a rather lower position because of the then still small winding diameter. With increasing winding diameter, the support shoe 5 is pivoted more and more upwards - here simply by rotating the support body 4 about its longitudinal axis - so that, as with conventional double support roller rollers, it is carried on two elongate regions which are spaced apart on the circumference of the winding becomes. It is of course the case that the radius of curvature of the support shoe 5 does not correspond to the smaller diameters of the winding, so that there is no significant advantage here over the conventional double support roller roller. However, as soon as the winding has a size in the region of its maximum diameter, the wing on which the winding is supported on the support shoe 5 increases considerably. (It is known that even with a roller with a hard, smooth surface, there is a pressing surface with a length in the circumferential direction between 20 and 25 mm with a large winding diameter and a correspondingly large drum weight.)

In Fig. 2 ist die oberste Stellung des Tragschuhes 5 bei vollendetem Wickeldurchmesser dargestellt. In den Figuren sind noch Schmiermittelleitungen 38 für den Tragschuh 5 und weitere Tragleisten angedeutet. Es ist auch möglich - bei durch Tragscheiben und stirnseitigen Enden des Mantels abgedichtetem Mantel - diesen mittels Druckluft unter einen inneren Überdruck zu setzen, so daß er ohne Führung durch Tragleisten 6 verhältnismäßig "rund" um den Träger 4 umläuft.In Fig. 2, the uppermost position of the support shoe 5 is shown with the winding diameter completed. Lubricant lines 38 for the support shoe 5 and further support strips are also indicated in the figures. It is also possible - in the case of a jacket sealed by supporting disks and the front ends of the jacket - to place it under an internal overpressure by means of compressed air, so that it rotates relatively "around" the carrier 4 without being guided by carrier strips 6.

Wie aus Fig. 2 erkennbar, wird der Tragschuh 5 so angeordnet, daß er das Hauptgewicht des Tambours T im Verhältnis zur weiteren Tragwalze 2 aufnimmt.As can be seen from Fig. 2, the support shoe 5 is arranged so that it takes up the main weight of the reel T in relation to the other support roller 2.

Ein notwendiger Schmierfilm zur Überwindung des Losbrechmomentes beim Anwickeln kann gebildet werden durch die Zuführung eines unter hohem Druck stehenden Schmiermittels zwischen dem Mantel und dem Tragschuh im Bereich der anliegenden Hülse. Außerdem kann das Anwickeln unterstützt werden durch in die Walze eingeleitete Druckluft, sofern man nicht fortwährend diesen Zustand ohnehin aufrecht erhält. Den "Durchmesser" der Mantelwalze - des flexiblen Walzenmantels - sollte man relativ groß wählen, z.B. größer als 800 mm. Dadurch wird die notwendige Umdrehungszahl, um einen bestimmten Tambourdurchmesser herzustellen, verhältnismäßig geringer, so daß die Lebensdauer des Mantels erhöht wird.A necessary lubricating film to overcome the breakaway torque during winding can be formed by supplying a lubricant under high pressure between the jacket and the support shoe in the area of the adjacent sleeve. In addition, the winding can be supported by compressed air introduced into the roller, provided that this condition is not continuously maintained anyway. The "diameter" of the jacket roller - the flexible roller jacket - should be chosen relatively large, e.g. larger than 800 mm. As a result, the number of revolutions required to produce a specific reel diameter is relatively lower, so that the service life of the jacket is increased.

Man kann auch günstigerweise für den Fall der Fig. 1 vorsehen, daß der Mantel elektrostatisch aufgeladen wird, um den Bahneinzug und die Bahntrennung zu unterstützen.In the case of FIG. 1, it can also be conveniently provided that the jacket is electrostatically charged in order to support web feeding and web separation.

Eine Schwenkvorrichtung können Hebel sein, die an den stirnseitigen Enden des Trägers 4 angreifen und die zum Beispiel durch hydraulische Hubelemente betätigt werden.A pivoting device can be levers which engage on the front ends of the carrier 4 and which are actuated, for example, by hydraulic lifting elements.

In Fig. 3 ist entsprechend der Darstellung in Fig. 1 eine Variante dargestellt, bei welcher der Tragschuh 5' auf dem rohrförmigen Träger 4' mit kreiszylindrischem Querschnitt verschwenkbar um eine zur Längsachse des Trägers bzw. des Bahnwickels parallele Achse angeordnet ist. Die Verschwenkbewegung wird durch hydraulische oder pneumatische Kolben-Zylinder-Einheiten 27 bewirkt, die an Laschen 29 des Tragschuhes angreifen. Der Mantel 7' wird dann noch über Tragblöcke 42 und 43 geführt, zu denen noch Schmiermittelleitungen 44 und 45 angedeutet sind. Ein weiteres Tragelement ist in diesem Falle ein hydrodynamisch wirksamer als Kolben betätigter Tragschuh 8, der im wesentlichen dem Tragschuh 5' diametral gegenüber angeordnet ist und dem in diesem Falle eine Antriebsrolle 32 zugeordnet ist, die am Umfang des flexiblen, schlauchartigen Mantels 7' angreift. Man kann diesen Antrieb auch nur für den Anfangszeitraum vorsehen, während welchem der Bahnwickel noch relativ klein ist und noch nicht ein so hohes Gewicht hat.FIG. 3 shows a variant corresponding to the representation in FIG. 1, in which the support shoe 5 'is arranged on the tubular carrier 4' with a circular cylindrical cross section so as to be pivotable about an axis parallel to the longitudinal axis of the carrier or the web winding. The pivoting movement is effected by hydraulic or pneumatic piston-cylinder units 27, which engage on tabs 29 of the carrier shoe. The jacket 7 'is then guided over support blocks 42 and 43, to which lubricant lines 44 and 45 are also indicated. A further supporting element in this case is a hydrodynamically effective carrying shoe 8 which is actuated as a piston and which is essentially arranged diametrically opposite the carrying shoe 5 'and which in this case is assigned a drive roller 32 which acts on the circumference of the flexible, tubular jacket 7'. Man can only provide this drive for the initial period during which the web winding is still relatively small and not yet so heavy.

Beim Beginn des Wickelvorganges - wenn im wesentlichen nur die Hülse 9 oder mit wenigen Windungen umwickelt vorhanden ist - befindet sich der Tragschuh 5' in der ausgezogen dargestellten Position. Er weist in seinem der Tragwalze 2 gegenüber befindlichen Bereich einen Tragteil 10 mit konvex gewölbter Tragfläche auf, um die Wickelhülse und den Wickel kleinen Durchmessers zu tragen. Sobald der Bahnwickel eine gewisse Größe erreicht hat, wird der Tragschuh in die strichpunktiert dargestellte Position 7'' um Achse 34 hochgeschwenkt, um ein einwandfreies Führen und Tragen des Wickels zu gewährleisten.At the beginning of the winding process - when essentially only the sleeve 9 or with a few turns is wrapped - the carrying shoe 5 'is in the position shown in the solid line. In its area opposite the support roller 2, it has a support part 10 with a convexly curved support surface in order to support the winding tube and the winding of small diameter. As soon as the web winding has reached a certain size, the support shoe is pivoted up to the position 7 ″ shown in dash-dotted lines around axis 34 in order to ensure proper guiding and carrying of the winding.

Praktisch wird hier durch das Verschwenken des Tragschuhes das gleiche erreicht wie bei der Einrichtung nach Figur 1 und 2. Hat der Bahnwickel etwa die dargestellte Größe W' erreicht, so wird der Tragschuh wieder allmählich heruntergeschwenkt, bis er wieder die ausgezogen dargestellte Position erreicht hat, um schließlich auf diese Weise auch den Tambour mit dem größten Wickeldurchmesser zu tragen.Practically, the pivoting of the support shoe achieves the same as in the device according to FIGS. 1 and 2. When the web wrap has approximately reached the size shown W ', the support shoe is gradually swiveled down again until it has reached the position shown in the undressed position. to finally carry the reel with the largest winding diameter in this way.

Wählt man einen sehr großen Durchmesser des flexiblen Mantels 7 bzw. 7' von mindestens 1500 mm, und ordnet die "zweite Tragwalze" 2 relativ weit oben in bezug auf den flexiblen Mantel an, kann man die Flächenpressung sehr weitgehend vermindern und somit einen sehr großen Bahnwickel-Durchmesser zulassen.If one chooses a very large diameter of the flexible jacket 7 or 7 'of at least 1500 mm, and arranges the "second support roller" 2 relatively high up with respect to the flexible jacket, one can reduce the surface pressure very largely and thus a very large one Allow web winding diameter.

Man kann auch noch, wie strichpunktiert angedeutet, mittels - strichpunktiert dargestellten - Druckschläuchen 46 anstelle der Kolbenzylindereinheiten 27 den Tragschuh 5' verschwenken. Er kann dadurch mit geringerer Wandstärke ausgeführt werden, weil er über seine ganze Länge von den Druckschläuchen unterstützt wird. Seine Durchbiegung - vor allem in der Mitte bzw. in den Mittelbereichen des Bahnwickels - ist dadurch wesentlich geringer und man kann den Außendurchmesser des hohlzylindrischen Tragkörpers 4' - bei gegebenem Durchmesser des flexiblen Mantels - eventuell größer ausführen.It is also possible, as indicated by dash-dotted lines, to pivot the support shoe 5 'by means of pressure hoses 46 (shown by dash-dotted lines) instead of the piston-cylinder units 27. As a result, it can be designed with a smaller wall thickness because it is supported by the pressure hoses over its entire length. Its deflection - especially in the middle or in the Central regions of the web winding - is thereby considerably smaller and the outer diameter of the hollow cylindrical support body 4 'can be made larger, given the diameter of the flexible jacket.

Man kann auch durch ein Schutzblech 31 das Anlaufen des Mantels 7' an "eckigen" Teilen (wie die Halterung der Kolben-Zylinder-Einheit 27) vermeiden.A mudguard 31 can also be used to prevent the jacket 7 'from starting up on "angular" parts (such as the mounting of the piston-cylinder unit 27).

In Fig. 4 ist eine Anordnung dargestellt, bei welcher die Walzen auf einem zweiarmigen Hebel 54 angeordnet sind, wobei sich der Träger 4, 55 des flexiblen Mantels 7 auf dem einen Arm und die starre Tragwalze 2 auf dem anderen Arm mit jeweils zugeordneten Lagern 58 bzw. 59 befinden. Solche Hebel sind natürlich an beiden Enden der Walzen vorgesehen. Die Verstellung der Hebel erfolgt mittels Hubelementen 52, vorzugsweise hydraulischen Zylinder-Kolben-Einheiten. Die Hebel sind auf Ständern 56 aufgelagert. Man kann durch diese Anordnung auch eventuell eine Anpassung der Position des Tragschuhes 5 an die unterschiedlichen Wickeldurchmesser vornehmen. Auf jeden Fall kann eine genaue Anpassung der Position der Tragwalzen hinsichtlich vibrationsfreiem Betrieb der Anordnung erfolgen.4 shows an arrangement in which the rollers are arranged on a two-armed lever 54, with the carrier 4, 55 of the flexible jacket 7 on one arm and the rigid support roller 2 on the other arm, each with associated bearings 58 or 59. Such levers are of course provided on both ends of the rollers. The levers are adjusted by means of lifting elements 52, preferably hydraulic cylinder-piston units. The levers are supported on stands 56. This arrangement can also be used to adapt the position of the support shoe 5 to the different winding diameters. In any case, the position of the support rollers can be precisely adjusted with regard to vibration-free operation of the arrangement.

Es ist hier die Variante gemäß den Figuren 1 und 2 berücksichtigt, wobei der Träger 4 über Achsstummel 55 aufgelagert ist.The variant according to FIGS. 1 and 2 is taken into account here, the carrier 4 being supported by stub axles 55.
