Description

Die Erfindung bezieht sich auf eine Wickelmaschine zum Aufwickeln einer Materialbahn, insbesondere einer Papier- oder Kartonbahn, auf mindestens eine Wickelhülse zu einer Wickelrolle mittels mindestens einer elastisch gelagerten Walze, auf der die Wickelrolle beim Aufwickeln auf- oder anliegt.The invention relates to a winding machine for winding a material web, in particular a paper or board web, on at least one winding tube to a winding roll by means of at least one elastically mounted roller on which the winding roll when winding up or rests.

Materialbahnen müssen, bevor sie versandt werden können, zu Versand- oder Fertigrollen aufgewickelt werden. Als Rollenkerne werden hierfür üblicherweise Wickelhülsen verwendet, die vorzugsweise aus Pappe bestehen. Die Fertigrollen werden dadurch erzeugt, dass sogenannte Mutter- oder Tambourrollen, die am Ausgang einer Papiermaschine oder nach der Satinage erzeugt werden, abgewickelt, in Längsrichtung geschnitten und dann jeweils auf Wickelhülsen aufgewickelt werden. Diese Wickelhülsen liegen entweder auf einer Stützwalze einer Stützwalzen-Wickelmaschine auf oder seitlich an dieser an, oder die Wickelhülsen liegen in einem von zwei Tragrollen einer Doppeltragwalzen-Wickelmaschine gebildeten Wickelbett.Material webs must be wound up into shipping or finishing rolls before they can be shipped. As reel cores usually winding cores are used, which are preferably made of cardboard. The finished rolls are produced by so-called mother or spool rolls, which are produced at the exit of a paper machine or after the calendering, unwound, cut in the longitudinal direction and then wound on each winding cores. These cores are either on a support roller of a back-up roll winding machine or laterally on this, or the cores are in one of two support rollers of a double carrier roll winding machine formed winding bed.

Im Fall einer Doppeltragwalzen-Wickelmaschine, wie sie beispielsweise aus der DE 200 13 319 U1 oder der EP 0 792 245 B1 bekannt ist, ist mindestens eine der beiden Tragwalzen angetrieben. Auf diese Weise liegen entsprechend der Anzahl der aus der ursprünglichen Materialbahn durch Längsschnitte erzeugten einzelnen Materialbahnen mehrere Wickelhülsen nebeneinander in dem Wickelbett, auch wenn nachfolgend aus Gründen der einfachen Darstellung stets nur eine einzige Wickelhülse in Verbindung mit einem auf ihr aufgewickelten Materialbahnwickel angesprochen wird. Es ist jedoch auch möglich, lediglich eine einzige Wickelrolle in einer Doppeltragwalzen-Wickelmaschine zu wickeln.In the case of a double carrier roll winding machine, as for example from the DE 200 13 319 U1 or the EP 0 792 245 B1 is known, at least one of the two support rollers is driven. In this way, according to the number of individual webs produced from the original material web by longitudinal cuts several cores next to each other in the winding bed, even if subsequently for reasons of simplicity always only a single winding tube is addressed in conjunction with a wound on her web winding. However, it is also possible to wind only a single winding roll in a double carrier roll winding machine.

In der EP 0 829 438 B1 wird eine Stützwalzen-Wickelmaschine beschrieben. In diesem Fall wird eine Materialbahn, auf eine Stützrolle gestützt, auf eine Wickelhülse aufgewickelt, während sie durch einen Spalt tritt, der zwischen der Stützrolle und der zu erzeugenden Wickelrolle ausgebildet ist, wobei die Wickelrolle zusätzlich durch eine weitere, zwei kleine Rollen umfassende Vorrichtung gestützt wird. In einer Stützwalzen-Wickelmaschine kann ebenfalls entweder nur eine einzige Wickelrolle gewickelt werden oder eine Mehrzahl von Wickelrollen, die jeweils in Wickelstationen durch einzelne Spannvorrichtungen gehalten werden, wobei die Spannvorrichtungen die Wickelrollen im Wechsel zu beiden Seiten von einer durch den Mittelpunkt der Stützrolle hindurchlaufenden senkrechten Achse halten, wobei die Verbindungslinien zwischen den Mittelpunkten der Wickelrollen und der Stützrolle jeweils nach beiden Seiten von der Senkrechten unter einem spitzen Winkel geneigt sind oder mit der Senkrechten einen rechten Winkel bilden. Hierbei können die Spannköpfe und die Wickelhülsen in den Wickelstationen auch verschiedene Durchmesser aufweisen.In the EP 0 829 438 B1 a backup roll winding machine will be described. In this case, a web supported on a support roll is wound on a winding mandrel as it passes through a nip formed between the support roll and the wound roll to be formed, the winding roll being additionally supported by another device comprising two small rolls becomes. In a back-up roll winding machine, either only a single winding roll can be wound, or a plurality of wound rolls each held in winding stations by individual tensioning devices, the tensioning devices alternately moving the winding rolls to either side from a vertical axis passing through the center of the backing roll hold, wherein the connecting lines between the centers of the bobbins and the support roller are inclined in each case to both sides of the vertical at an acute angle or form a right angle with the vertical. Here, the clamping heads and the winding tubes in the winding stations can also have different diameters.

Beim Wickeln von Rollen werden durch Schwingungen der Rolle und der beiden Tragwalzen Eindrückungen in der Rolle verursacht, die durch Resonanzen immer an derselben Umfangsstelle auftreten und dadurch immer stärker werden. Dadurch wird einerseits die gesamte Wickelmaschine schädlichen Schwingungsbeanspruchungen unterworfen, und andererseits wird die Wickelrolle mit Wickelfehlern gewickelt.When winding rolls are caused by vibrations of the roll and the two support rollers indentations in the role, which occur by resonances always at the same circumferential location and thus become stronger. As a result, on the one hand, the entire winding machine is subjected to harmful vibration stresses, and on the other hand, the winding roll is wound with winding faults.

Aus der DE 71 21 923 U1 ist eine Trageinrichtung für aus Bahnen aufgewickelte Rollen bekannt, in der wenigstens eine der beiden Tragwalzen elastisch gelagert ist. Durch die elastische Lagerung erhält die eine Tragwalze bei gleicher Ausbildung beider Walzen eine zur anderen unterschiedliche Eigenfrequenz, so dass eine Summierung der Schwingungen der beiden Walzen und damit eine Rollenbeschädigung ausgeschlossen wird.From the DE 71 21 923 U1 is a support device for rolls wound from webs known in which at least one of the two support rollers is elastically mounted. Due to the elastic support receives the one support roller with the same design of both rolls a different natural frequency to each other, so that a summation of the vibrations of the two rolls and thus a roll damage is excluded.

Durch die DE 73 05 837 U1 ist eine Trageinrichtung bekannt geworden, in der beide Tragwalzen auf Federn abgestützt sind. Durch diese Maßnahme wird eine Entkopplung und Dämpfung von Schwingungen erreicht. Es lässt sich auch der Einsatz von Dämpfungselementen vorsehen, deren Dämpfungswirkung in Abhängigkeit von der Lagerbelastung einstellbar ist.By the DE 73 05 837 U1 is a support device has become known in the both support rollers are supported on springs. By this measure, a decoupling and damping of vibrations is achieved. It can also provide the use of damping elements whose damping effect is adjustable in dependence on the bearing load.

Ferner wird versucht, durch eine geeignete Dimensionierung von Walzen und Lagerungen, insbesondere durch die Lagerung des Walzenmantels, eine hohe mechanische Steifigkeit zu erreichen. Aufgrund der steigenden Arbeitsbreite in der Herstellung von Materialbahnen werden hier jedoch Grenzen erreicht. Größere Walzendurchmesser führen bei der Anwicklung zu ungünstigen geometrischen Verhältnissen im Wickelbett; segmentierte Walzen verursachen Probleme bei der Wickelqualität.Furthermore, an attempt is made to achieve a high mechanical rigidity by suitably dimensioning rollers and bearings, in particular by supporting the roller jacket. Due to the increasing working width in the production of material webs, however, limits are reached here. Larger roller diameters lead to unfavorable geometrical conditions in the winding bed during winding; segmented rolls cause problems in winding quality.

Aus der DE 2016116 ist eine Wickelmaschine bekannt, in der eine Walze auf der unteren Seite ihres Mantels während des Aufwickelns durch ein Abstützmittel abgestützt ist.From the DE 2016116 For example, a winding machine is known in which a roll is supported on the lower side of its shell during winding by a support means.

Es ist die Aufgabe der Erfindung, eine verbesserte Wickelmaschine zu schaffen, in der die mindestens eine Walze mit einer erhöhten Steifigkeit im Wickelbett liegt; gleichzeitig soll eine aktive und eine passive Schwingungsdämpfung erreicht werden.It is the object of the invention to provide an improved winding machine in which the at least one roller with an increased rigidity lies in the winding bed; At the same time an active and a passive vibration damping should be achieved.

Erfindungsgemäß wird diese Aufgabe bei einer Wickelmaschine der eingangs genannten Art durch die Merkmale des Anspruchs 1 gelöst.According to the invention this object is achieved in a winding machine of the type mentioned by the features of claim 1.

Das Abstützmittel umfasst einen Aktor zur Lageregelung, eine Feder, einen Dämpfer und eine Messeinrichtung; letztere dient dazu, die Position der Tragwalzen einer Doppeltragwalzen-Wickelmaschine oder der einen Tragwalze in einer Stützwalzen-Wickelmaschine genau festlegen zu können.The support means comprises an actuator for position control, a spring, a damper and a measuring device; the latter serves to be able to precisely determine the position of the carrier rollers of a double carrier roll winding machine or of the one carrier roll in a backup roll winding machine.

Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen, der Beschreibung und den Zeichnungen.Advantageous developments emerge from the subclaims, the description and the drawings.

Um während des Wickelvorgangs die Lage der wenigstens einen Walze unter dem sich vergrößernden Gewicht des Wickels konstant einhalten zu können, umfasst das Abstützmittel eine Steuer- oder eine Regeleinrichtung. Diese sorgt dafür, dass sich die Walzenmitte bei einer Veränderung der Federsteifigkeit und der Belastung nicht ändert. Durch den Einsatz einer Aktorik unter einem federnden Element wird das Einfedern des aus dem Wickel und der mindestens einen Walze bestehenden Schwingungssystems und damit dessen Anregung verhindert. Die Geometrie des Walzenbettes bleibt somit unter allen Umständen erhalten; auch die Walzenmitte ändert ihre Lage bei einer Veränderung der Federsteifigkeit und der durch die Wickelrolle eingeleiteten Kräfte nicht.In order to be able to keep the position of the at least one roller constant under the increasing weight of the roll during the winding process, the support means comprises a control or a regulating device. This ensures that the roll center does not change with a change in the spring stiffness and the load. By using an actuator under a resilient element, the compression of the existing of the winding and the at least one roller vibration system and thus its excitation is prevented. The geometry of the roll bed thus remains under all circumstances; Also, the roll center does not change its position with a change in the spring stiffness and introduced by the winding roll forces.

Besonders geeignet ist eine Ausgestaltung der Wickelmaschine, in der die Federsteifigkeit der Feder und/oder die Dämpfung des Dämpfers passiv und/oder aktiv veränderbar ist. Es besteht eine Vielzahl von Möglichkeiten zur passiven Ausgestaltung der Federn; bevorzugt kommen Federn in Form von Biegebalken oder als Spiralfedern zum Einsatz. Selbstverständlich ist jedoch auch der Einsatz einer aktiven Dämpfung möglich.Particularly suitable is an embodiment of the winding machine in which the spring stiffness of the spring and / or the damping of the damper is passively and / or actively changeable. There are a variety of ways for passive design of the springs; Preferably, springs are used in the form of bending beams or as spiral springs. Of course, however, the use of active damping is possible.

Auf der Unterseite der mindestens einen Walze wird wenigstens eine Rolle auf wenigstens einer Seite der Walze, bezogen auf ihre Achse, oder eine Mehrzahl von axial hintereinander angeordneten Rollen auf wenigstens einer Seite der Walze, bezogen auf ihre Achse, angeordnet. Dadurch lässt sich die Walze gezielt über ihre gesamte Länge nach oben drücken. Mit sich änderndem Gewicht der auf der Walze lastenden Wickelrolle lässt sich der Anpressdruck der die Walze von unten stützenden Rollen anpassen.On the underside of the at least one roller at least one roller on at least one side of the roller, with respect to its axis, or a plurality of axially successively arranged rollers on at least one side of the roller, with respect to its axis, is arranged. As a result, the roller can be selectively pushed up over its entire length. As the weight of the winding roll loaded on the roll changes, the contact pressure of the rolls supporting the roll from below can be adjusted.

Zusätzlich zu dieser Maßnahme lässt sich erfindungsgemäß vorsehen, dass auf der Unterseite der mindestens einen Walze wenigstens ein Luftlager oder wenigstens ein Magnetlager angeordnet ist.In addition to this measure, according to the invention it can be provided that at least one air bearing or at least one magnetic bearing is arranged on the underside of the at least one roller.

Die Erfindung bezieht sich auch auf ein Verfahren zum Aufwickeln einer Materialbahn, insbesondere einer Papier- oder Kartonbahn, in einer Wickelmaschine auf eine Wickelhülse zu mindestens einer Wickelrolle mittels mindestens einer elastisch gelagerten Walze, auf der die Wickelrolle beim Aufwickeln auf- oder anliegt, gemäß den Merkmalen des Anspruchs 6.The invention also relates to a method for winding a material web, in particular a paper or board web, in a winding machine on a winding tube to at least one winding roll by means of at least one elastically mounted roller on which the winding roll during winding up or bears, according to the Features of claim 6.

Nachstehend wird die Erfindung in Ausführungsbeispielen anhand der Zeichnungen näher erläutert.The invention will be explained in more detail in exemplary embodiments with reference to the drawings.

By adjusting the air pressure in the air bearings 4 to 7, respectively, the contact pressure of the air bearings 4 to 7 against the support rollers 1, 2 set.
