Description

Wendehaspel sowie Verfahren zum Betrieb eines Wendehaspels Reversible reel and method for operating a reversible reel

Die Erfindung betrifft einen Wendehaspel mit einem Rotor, an welchem wenigstens ein mit einem Drehantrieb versehener Haspeldorn zum Aufwickeln von Band zu einem Coil exzentrisch zu einer Drehachse des Rotors angeordnet ist, mit wenigstens einer angetriebenen Dornstützeinrichtung, umfassend eine Dornstütze, welche einen Lagerkopf zur Unterstützung des freien Endes des wenigstens einen Haspeldorns aufweist. Die Erfindung betrifft weiterhin ein Verfahren zum Aufwickeln von Bändern, insbesondere von Metallbändern zu einem Coil, insbesondere unter Verwendung des erfindungsgemäßen Wendehaspels. The invention relates to a reversible reel with a rotor, on which at least one reel mandrel provided with a rotary drive for winding tape into a coil is arranged eccentrically to an axis of rotation of the rotor, with at least one driven mandrel support device, comprising a mandrel support which supports a bearing head free end of the at least one reel mandrel. The invention further relates to a method for winding strips, in particular metal strips, into a coil, in particular using the reversible reel according to the invention.

Gattungsgemäße Haspel sind im Stand der Technik grundsätzlich bekannt. Diese werden beispielsweise sowohl in Kalt- als auch in Warmbandwalzwerken zum Aufwickeln des Bandes verwendet. Generic reels are generally known in the prior art. These are used, for example, in both cold and hot strip rolling mills to wind up the strip.

Ein gewalztes Metallband kann beispielsweise nach dem Walzen auf einen Haspeldorn oder auf eine auf den Haspeldorn aufgesteckte Wickelhülse aufgewickelt und später wieder abgewickelt werden. Zur Realisierung kürzester Wickelbundfolgen, speziell im sogenannten Kontibetrieb werden Wendehaspel verwendet, die wenigstens zwei Haspeldorne aufweisen und bei denen die Positionen der Haspeldorne während eines Haspelvorgangs verändert wird. Die Haspeldorne sind jeweils angetrieben und auf einem Rotor gelagert. Zu Beginn eines Aufwickelvorgangs wird der Rotor des Haspels so gedreht, dass ein noch leerer Haspeldorn in einer Anwickelposition positioniert wird. In dieser Position wird dann das Band auf dem Haspeldorn angewickelt. Unter dem Begriff „Anwickeln“ wird für gewöhnlich verstanden, dass zunächst ein bis drei Windungen des Bandes auf dem Haspeldorn aufgewickelt werden. Nach dem erfolgten Anwickeln wird für das weitere Aufwickeln eine Zugspannung (Bandzug) in dem Band aufgebaut. Während des weiteren Aufwickelns wird der Haspeldorn aus der Anwickelposition in eine fertige Wickelposition gedreht. Dort erfolgt das Fertigwickeln des Bandes zu einem Coil bzw. zu einem Bund. Das Coil kann nach der Fertigstellung aus der Fertigwickelposition herausgenommen und weitertransportiert werden. After rolling, a rolled metal strip can, for example, be wound onto a reel mandrel or onto a winding tube fitted onto the reel mandrel and can later be unwound again. To achieve the shortest winding bundle sequences, especially in so-called continuous operation, reversible reels are used which have at least two reel mandrels and in which the positions of the reel mandrels are changed during a reel operation. The reel mandrels are each driven and mounted on a rotor. At the beginning of a winding process, the rotor of the reel is rotated so that an even empty reel mandrel is positioned in a winding position. In this position the tape is then wound onto the reel mandrel. The term "winding" is usually understood to mean that one to three turns of the tape are first wound on the coiler mandrel. After the winding has taken place, a tensile stress (tape tension) is built up in the tape for further winding. During the further winding the reel mandrel turned from the winding position into a finished winding position. There the tape is finished to a coil or a bundle. After completion, the coil can be removed from the finished winding position and transported further.

Bei einem Wendehaspel sind die Flaspeldorne einseitig, d. h. an einem antriebsseitigen Ende fest gelagert. Beim Flaspeln eines Metallbandes ist jedoch eine beiderseitige Abstützung des Flaspeldorns und eine dadurch bedingte symmetrische Biegelinie des Flaspeldorns wichtig, um einen stabilen Bandlauf beim Flaspeln sicherzustellen und um die Wickelgenauigkeit des Bandes auf dem Flaspeldorn zu verbessern. In a reversible reel, the mandrel is unilateral, i.e. H. fixed at one end on the drive side. When coiling a metal strip, it is important to support the coiler mandrel on both sides and the resulting symmetrical bending line of the coiler mandrel in order to ensure stable strip travel during coiling and to improve the winding accuracy of the strip on the coiler mandrel.

Aus der WO 2018/041673 A1 ist eine Abstützvorrichtung für einen Wendehaspel zum Flaspeln eines Metallbandes bekannt, die wenigstens eine in einen Stützkontakt mit einem freien Endabschnitt eines Flaspeldorns bringbare Abstützeinheit aufweist. Die Abstützeinheit ist auf einer Schiene geführt, die vor dem Flaspel angeordnet ist und die mit einem eigenen Antrieb der Kreisbahn des Flaspeldorns folgt. Die Führungsschiene vor dem Flaspel verbaut den bedienungsseitigen Bereich vor dem Flaspel. Darüber hinaus ist die komplette Ausführung verhältnismäßig schwer und aufwändig. From WO 2018/041673 A1, a support device for a reversible reel for flaking a metal strip is known, which has at least one support unit that can be brought into support contact with a free end section of a flake mandrel. The support unit is guided on a rail which is arranged in front of the flap and which follows the circular path of the flap mandrel with its own drive. The guide rail in front of the bottle blocks the area on the operator side in front of the bottle. In addition, the complete execution is relatively difficult and complex.

Aus der EP 1 886 951 A1 ist eine Wickelmaschine zum Aufwickeln einer durch Längsschnitte einer in Streifen unterteilten Materialbahn, insbesondere einer Papierbahn, Kunststoff- oder Metallfolie bekannt. Die Wickelmaschine umfasst zwei sich quer über die Maschinenbreite erstreckende Wickelwellen, die zum Bewegen von einer Wickelposition zu einer Entladeposition und zurück an einer Maschinenseite in einer schwenkbaren Wendeeinrichtung gelagert sind. An der zu der Wendeeinrichtung entgegengesetzten Maschinenseite ist eineEP 1 886 951 A1 discloses a winding machine for winding up a material web divided into strips by longitudinal cuts, in particular a paper web, plastic or metal foil. The winding machine comprises two winding shafts which extend across the machine width and are mounted on a machine side in a pivotable turning device for moving from a winding position to an unloading position and back. On the machine side opposite the turning device is one

Stützvorrichtung mit einem Stützelement angeordnet, das mittels eines Antriebs vertikal bewegbar ist und dessen Ende eine Wickelwelle auf dem Weg von der Wickelposition in die Entladeposition unterstützt. Das Stützelement ist als motorisch ausfahrbare Stütze ausgebildet, die als Schwinge in einem Drehgelenk gelagert ist. Das Stützelement ist so von einer Wickelposition in eine Entladeposition schwenkbar, wobei das Schwenken mittels eines Aktuators erfolgt, sodass die Schwenkbewegung eine Kreisbahn beschreibt, die der Kreisbahn der Wendeeinrichtung entspricht. Bei der in der EP 1 886 951 A1 beschriebenen Wickelmaschine ist ein Wickelvorgang während der Bewegung der Wendeeinrichtung unter Bandzug nicht vorgesehen. Vielmehr ist vorgesehen, den Wickelvorgang in der Wickelposition durchzuführen und danach die betreffende Wickelrolle in die Entladeposition zu drehen Support device arranged with a support element which is vertically movable by means of a drive and the end of which supports a winding shaft on the way from the winding position into the unloading position. The support element is as Motor-driven extendable support, which is mounted as a rocker in a swivel. The support element can thus be pivoted from a winding position into an unloading position, the pivoting being effected by means of an actuator, so that the pivoting movement describes a circular path that corresponds to the circular path of the turning device. In the winding machine described in EP 1 886 951 A1, a winding process is not provided during the movement of the turning device under tape tension. Rather, it is provided to carry out the winding process in the winding position and then to turn the winding roll in question into the unloading position

Insbesondere beim Wickeln von Metallbändern aus Walzwerken sind verhältnismäßig hohe Bundgewichte zu handhaben. Der Haspeldorn hat bereits ein sehr hohes Eigengewicht. Deshalb hängt sein freies Ende gegenüber seinem rotorseitigen Ende dann bereits durch, wenn er nicht mit einem Metallband gewickelt ist. Unter der Last des aufgewickelten Metallbandes verstärkt sich die einseitige Verformung. Hinzu kommt die Wirkung des Bandzuges des unter Zugkraft aufgewickelt Metallbandes. Das Durchhängen oder Herabhängen des freien Endes des Haspeldorns ist insbesondere deshalb nachteilig, weil die Wickelgenauigkeit des Bandes beeinträchtigt wird. Diese Wickelungenauigkeit hat darüber hinaus negative Auswirkungen auf die Planheit des Bandes. Especially when winding metal strips from rolling mills, relatively high coil weights have to be handled. The reel mandrel already has a very high weight. Therefore, its free end sags with respect to its rotor-side end when it is not wound with a metal band. The one-sided deformation increases under the load of the wound metal strip. In addition, there is the effect of the strip tension of the metal strip wound under tensile force. The sagging or hanging down of the free end of the reel mandrel is particularly disadvantageous because the winding accuracy of the band is impaired. This winding inaccuracy also has a negative impact on the flatness of the belt.

Der Erfindung liegt daher die Aufgabe zugrunde, einen bekannten Wendehaspel dahingehend weiterzubilden, dass die Durchbiegung des freien Endes des Haspeldorns während des gesamten Wickelvorgangs zuverlässig verringert wird. Der Erfindung liegt weiterhin die Aufgabe zugrunde, ein entsprechendes Verfahren bereitzustellen. The invention is therefore based on the object of developing a known reversible reel in such a way that the deflection of the free end of the reel mandrel is reliably reduced during the entire winding process. Another object of the invention is to provide a corresponding method.

Erfindungsgemäß ist ein Wendehaspel mit einem Rotor vorgesehen, an welchem wenigstens ein mit einem Drehantrieb versehener Haspeldorn zum Aufwickeln von Band zu einem Coil exzentrisch zu einer Drehachse des Rotors angeordnet ist, mit wenigstens einer angetriebenen Dornstützeinrichtung, umfassend eine Dornstütze, welche einen Lagerkopf zur Unterstützung eines freien Endes des wenigstens einen Haspeldorns aufweist, wobei der Lagerkopf entsprechend einer veränderlichen Position des Haspeldorns mit dem Haspeldorn bei einer Überführung des Haspeldorns von einer Anwickelposition in eine Fertigwickelposition bewegbar ist, wobei die Dornstütze als eine erste Kolben- Zylinder-Anordnung ausgebildet ist und die Dornstütze schwenkbar über ein Dornstützenlager auf einem tangential zu einer Kreisbahn des Haspeldorns verfahrbaren Schlitten abgestützt ist, und wobei die Neigung der Dornstütze und die Position des Lagerkopfs so verstellbar sind, dass die Dornstütze entsprechend oder parallel zu einer resultierenden Kraft aus Gewichtskraft des Coils und Zugkraft auf das Band ausgerichtet ist. According to the invention, a reversible reel with a rotor is provided, on which at least one reel mandrel provided with a rotary drive for winding tape into a coil is arranged eccentrically to an axis of rotation of the rotor, with at least one driven mandrel support device, comprising a mandrel support which supports a bearing head Free end of the at least one reel mandrel, wherein the bearing head is movable according to a variable position of the reel mandrel with the reel mandrel when the reel mandrel is transferred from a winding position to a finished winding position, the mandrel support being designed as a first piston-cylinder arrangement and the mandrel support is pivotally supported via a mandrel support bearing on a slide which can be moved tangentially to a circular path of the coiler mandrel, and the inclination of the mandrel support and the position of the bearing head are adjustable such that the mandrel support is corresponding to or parallel to an r resulting force from the weight of the coil and tensile force is aligned to the tape.

Die Position des Lagerkopfs ist vorzugsweise bezogen auf die Drehachse des Rotors radial verstellbar. Die Erfindung kann dahingehend zusammengefasst werden, dass erfindungsgemäß eine Dornstützeinrichtung mit einem mitfahrenden Dornstützenlager bereitgestellt wird, welches das freie Ende des Haspeldorns in einer Anwickelposition und während der Überführung des Haspeldorns von der Anwickelposition in die Fertigwickelposition unterstützt, wobei sich der Lagerkopf der Dornstützeinrichtung sowohl während des Anwickelns als auch zeitweise während des Fertigwickelns mit dem freien Ende des Haspeldorns in Eingriff befinden kann und zwar so, dass in verhältnismäßig einfacher Art und Weise die Dornstütze nicht nur der zunehmenden Gewichtskraft sondern auch der Bandzugkraft entgenwirkt. Erfindungsgemäß lässt sich das Dornstützenlager so verstellen, dass zu jeder Kombination aus Bandzug und Bundgewicht auch während des Wickelvorgangs eine Einstellung wählbar ist, die eine entsprechende Unterstützung des Haspeldorns ermöglicht. Die Dornstütze wird während des Betriebs des Wendehaspels so verstellt, dass optimal Einfluss auf die Verbiegung des Haspeldorns genommen werden kann. Die Unterstützung des Haspeldorns erfolgt idealerweise immer, auch während des Umlaufs, etwa in Richtung der resultierenden Kraft aus Bandzug und Gewichtskraft des Bundes bzw. des Coils. Das hat insbesondere den Vorteil, dass in das System keine Kippmomente übertragen werden, die zusätzlich aufgefangen werden müssten. The position of the bearing head is preferably radially adjustable with respect to the axis of rotation of the rotor. The invention can be summarized in that, according to the invention, a mandrel support device with a traveling mandrel support bearing is provided, which supports the free end of the reel mandrel in a winding position and during the transfer of the reel mandrel from the winding position to the finished winding position, the bearing head of the mandrel support device being supported both during the Winding as well as temporarily during the finish winding with the free end of the reel mandrel can be in such a way that the mandrel support not only counteracts the increasing weight but also the belt tension in a relatively simple manner. According to the invention, the mandrel support bearing can be adjusted so that a setting can be selected for each combination of tape tension and coil weight, even during the winding process, which enables the reel mandrel to be supported accordingly. The mandrel support is adjusted during operation of the reversible reel so that the bending of the reel mandrel can be optimally influenced. Ideally, the reel mandrel is always supported, even during rotation, for example in the direction of the resulting force from the strip tension and the weight of the coil or coil. This has the particular advantage that no tilting moments that would have to be absorbed are transferred to the system.

„Mitfahrend“ im Sinne der Erfindung meint, dass die Dornstütze während der Drehung des Rotors der dabei vollzogenen Kreisbewegung des Haspeldorns und des darauf aufgewickelten Bundes folgt. “Traveling” in the sense of the invention means that the mandrel support follows the circular movement of the coiler mandrel and the coil wound on it during the rotation of the rotor.

Vorzugsweise umfasst der Wendehaspel gemäß der Erfindung zusätzlich ein stationäres Außenlager, welches in der Fertigwickelposition gegen den Haspeldorn geschwenkt wird. Sowohl der Lagerkopf der Dornstützeinrichtung als auch ein entsprechend ausgebildeter Lagerkopf eines stationären Außenlagers sind so ausgebildet, dass sie jeweils an einem anderen Umfangsabschnitt des Haspeldorns auf derselben Länge des Haspeldorns angreifen können. Dadurch ist es möglich, den Haspeldorn in der Fertigwickelposition mit dem stationären Außenlager in Eingriff zu bringen und sodann die Dornstützeinrichtung zurück in die Ausgangsposition zu verfahren. The reversible reel according to the invention preferably additionally comprises a stationary outer bearing which is pivoted against the reel mandrel in the finished winding position. Both the bearing head of the mandrel support device and a correspondingly designed bearing head of a stationary outer bearing are designed such that they can each engage another circumferential section of the coiler mandrel on the same length of the coiler mandrel. This makes it possible to engage the reel mandrel in the finished winding position with the stationary outer bearing and then to move the mandrel support device back into the starting position.

Der Wendehaspel gemäß der Erfindung umfasst vorzugsweise zwei jeweils einseitig auf dem Rotor drehbeweglich gelagerte Haspeldorne, die einander diametral gegenüberliegend angeordnet sind. Vorzugsweise ist die Dornstütze über eine auf dem Schlitten befestigte Stelleinrichtung in der Neigung verstellbar. Über den Schlitten lässt sich in Kombination mit der in der Neigung und Länge verstellbaren Dornstütze besonders einfach eine Neigungsverstellung durch Überlagerung einer Rotationsbewegung und einer Linearbewegung bewerkstelligen. The reversible reel according to the invention preferably comprises two reel mandrels, each of which is rotatably mounted on one side on the rotor and which are arranged diametrically opposite one another. The mandrel support can preferably be adjusted in inclination by means of an adjusting device fastened on the slide. In combination with the mandrel support, which can be adjusted in incline and length, the slide can be adjusted particularly easily by superimposing a rotational movement and a linear movement.

Vorzugsweise ist als Stelleinrichtung für die Verstellbarkeit der Neigung der Dornstütze eine zweite Kolben-Zylinder-Anordnung vorgesehen. Sowohl die erste als auch die zweite Kolben-Zylinder-Anordnung ist vorzugsweise als Hydraulikzylinder ausgebildet, deren Kraft verhältnismäßig einfach und fein regelbar ist. Beide Kolben-Zylinder-Anordnungen können sowohl mit Sensoren für die Kraftmessung als auch mit Sensoren für die Wegaufnahme versehen sein. A second piston-cylinder arrangement is preferably provided as the adjusting device for the adjustability of the inclination of the mandrel support. Both the first and the second piston-cylinder arrangement are preferably designed as hydraulic cylinders, the force of which can be regulated relatively easily and finely. Both piston-cylinder arrangements can be provided with sensors for force measurement as well as with sensors for displacement measurement.

Alternativ kann die Neigungsverstellung für die Dornstütze mittels eines hydraulischen oder elektrischen Drehantriebs bewerkstelligt werden. Alternatively, the tilt adjustment for the mandrel support can be accomplished by means of a hydraulic or electrical rotary drive.

Bevorzugt ist der Schlitten über eine dritte Kolben-Zylinder-Anordnung tangential zu Drehachse des Rotors verschiebbar. Bei einer ebenen Aufstellung des Wendehaspels gemäß der Erfindung kann der Schlitten bezogen auf die Aufstellungsebene horizontal verfahrbar bzw. verschiebbar sein. Alternativ kann der Schlitten beispielsweise auf einem Zahnstock mittels eines Zahntriebs verstellbar sein. Zweckmäßigerweise ist eine Steuerung vorgesehen, mit welcher die Dornstützeinrichtung so angesteuert wird, dass die Dornstütze während des Aufwickelvorgangs einer Kreisbahn des Doms wenigstens über einen Teilkreisabschnitt folgt. Die der Erfindung zugrunde liegende Aufgabe wird weiterhin gelöst durch ein Verfahren zum Aufwickeln von Bändern, insbesondere von Metallbändern zu einem Coil oder Bund, mittels eines Wendehaspels mit einem Rotor, an welchem wenigstens ein mit einem Drehantrieb versehener Haspeldorn zum Aufwickeln von Band exzentrisch zu einer Drehachse des Rotors angeordnet ist, mit wenigstens einer angetriebenen Dornstützeinrichtung, umfassend eine Dornstütze, welche einen Lagerkopf zur Unterstützung eines freien Endes des wenigstens einen Haspeldorns aufweist, wobei das Verfahren folgende Schritte aufweist: The slide can preferably be displaced tangentially to the axis of rotation of the rotor via a third piston-cylinder arrangement. In the case of a flat installation of the turning reel according to the invention, the carriage can be moved or displaced horizontally with respect to the installation plane. Alternatively, the slide can be adjustable, for example, on a toothed rack by means of a pinion. A control is expediently provided, with which the mandrel support device is controlled in such a way that the mandrel support follows a circular path of the cathedral during the winding-up process at least over a partial circle section. The object on which the invention is based is also achieved by a method for winding tapes, in particular metal tapes a coil or bundle, by means of a reversible reel with a rotor, on which at least one reel mandrel provided with a rotary drive for winding tape is arranged eccentrically to an axis of rotation of the rotor, with at least one driven mandrel support device, comprising a mandrel support which supports a bearing head free end of the at least one reel mandrel, the method comprising the following steps:

drehen des Rotors zum Überführen des zunächst leeren Haspeldorns in eine Anwickelposition, unterfangen eines freien Endes des Haspeldorns mit dem Lagerkopf der Dornstütze, anheben des freien Endes des Haspeldorns mit der Dornstütze, anwickeln des Bandes in der Anwickelposition, drehen des Rotors zum Überführen des Haspeldorns mit dem angewickelten Coil in eine Fertigwickelposition, wobei die Dornstütze während einer Drehung des Rotors von der Anwickelposition in die Fertigwickelposition so nachgeführt wird, dass der Lagerkopf mit dem freien Ende der Dornstütze lastaufnehmend in Eingriff bleibt, unterfangen des Haspeldorns mittels eines stationären Außenlagers und fertigwickeln des Bandes, wobei ein Verstellen der Neigung der Dornstütze vor und/oder während des Anwickelns und/oder während der Überführung des Haspeldorns in die Fertigwickelposition so erfolgt, dass der Winkel zwischen der Dornstütze und einer Lotrechten dem Winkel zwischen einer resultierenden Kraft aus einer Bandzugkraft und Gewichtskraft des Coils entspricht. turn the rotor to transfer the initially empty reel mandrel into a winding position, undertake a free end of the reel mandrel with the bearing head of the mandrel support, lift the free end of the reel mandrel with the mandrel support, wind up the band in the winding position, turn the rotor to transfer the reel mandrel the wound coil into a finished winding position, the mandrel support being tracked during rotation of the rotor from the winding position to the finished winding position so that the bearing head remains in load-receiving engagement with the free end of the mandrel support, underpinning the coiler mandrel by means of a stationary outer bearing and finishing winding of the band , wherein the inclination of the mandrel support is adjusted before and / or during the winding and / or during the transfer of the reel mandrel into the finished winding position such that the angle between the mandrel support and a perpendicular is the angle between a resultant force from a tape tension t and weight of the coil.

Zweckmäßigerweise erfolgt die Verstellung der Neigung der Dornstütze während der Drehung des Rotors von der Anwickelposition in die Fertigwickelposition. The inclination of the mandrel support is expediently adjusted during the rotation of the rotor from the winding position to the finished winding position.

Bevorzugt wird die Nachführbewegung der Dornstütze wenigstens teilweise durch eine Überlagerung einer Linearbewegung der Dornstützeinrichtung mit einer Schwenkbewegung der Dornstütze vollzogen. Wenn die erste, zweite und dritte Kolben-Zylinder - Anordnung des Wendehaspels gemäß der Erfindung jeweils mit Weggebern versehen sind, können die Zylinder so gesteuert werden, dass sie der Kreisbahn des Haspeldorns folgen. Bei einer vorteilhaften Variante des Verfahrens gemäß der Erfindung ist vorgesehen, dass das freie Ende des Haspeldorns in Abhängigkeit der Gewichtskraft des Coils und/oder des Bandzuges abgestützt wird. Dabei kann die Lastaufnahme der Dornstütze in Eingriff mit dem freien Ende des Haspeldorns gemessen werden, wobei die Stützkraft der Dornstütze so geregelt wird, dass dessen durch Gewichtskraft und Bandzug verursachte Absenkung kompensiert wird. Hierzu ist die erste Kolben-Zylinder-Anordnung bevorzugt kraftgeregelt, sodass das freie Ende des Haspeldorns immer mit der optimalen Stützkraft angehoben wird The tracking movement of the mandrel support is preferably carried out at least partially by superimposing a linear movement of the mandrel support device with a pivoting movement of the mandrel support. If the first, second and third piston-cylinder arrangements of the turning reel according to the invention are each provided with displacement sensors, the cylinders can be controlled so that they follow the circular path of the reel mandrel. In an advantageous variant of the method according to the invention it is provided that the free end of the reel mandrel is supported as a function of the weight of the coil and / or the strip tension. The load bearing capacity of the mandrel support in engagement with the free end of the reel mandrel can be measured, the supporting force of the mandrel support being regulated in such a way that its lowering caused by the weight force and the belt tension is compensated for. For this purpose, the first piston-cylinder arrangement is preferably force-controlled, so that the free end of the reel mandrel is always raised with the optimal supporting force

Die Erfassung der Neigung der ersten Kolben-Zylinder-Anordnung kann mittels Wegmessung in Zylinder oder direkter Winkelmessung erfolgen. The inclination of the first piston-cylinder arrangement can be detected by means of distance measurement in cylinders or direct angle measurement.

Eine Regelung der Neigungsverstellung der ersten Kolben-Zylinder-Anordnung kann in Abhängigkeit einer in einen Winkel zur Stützkraft der Dornstütze einwirkenden Kraft erfolgen. Wird die Dornstütze nur in ihrer Längsrichtung belastet, wirkt keine Querkraft und mithin kein Moment auf die Dornstütze. Die Regelung kann vorsehen, dass die Neigung der Dornstütze so verstellt wird, dass die auf diese in einem Winkel zur Stützrichtung einwirkende Kraft minimal ist. The inclination adjustment of the first piston-cylinder arrangement can be regulated as a function of a force acting at an angle to the supporting force of the mandrel support. If the mandrel support is only loaded in its longitudinal direction, there is no transverse force and therefore no moment on the mandrel support. The regulation can provide that the inclination of the mandrel support is adjusted so that the force acting on it at an angle to the direction of support is minimal.

Nach einer Variante der Regelung von Position und Neigung der Dornstütze kann vorgesehen sein, eine reine Positionsregelung vorzusehen. According to a variant of the regulation of the position and inclination of the mandrel support, provision can be made for a pure position regulation.

Alternativ hierzu kann die Regelung von Position und Neigung der Dornstütze überwiegend als Kraftregelung erfolgen. As an alternative to this, the position and inclination of the mandrel support can mainly be regulated as force regulation.

Unabhängig davon, ob die Regelung als Kraftregelung oder Positionsregelung erfolgt, kann die Soll-Neigung und die Soll-Lage der Dornstütze von einem Drehgeber am Rotor vorgegeben werden. Die Regelungen kann alternativ in Abhängigkeit der Lage des Haspeldorns erfolgen. Bei einer Variante des Verfahrens gemäß der Erfindung ist vorgesehen, dass die auf die Dornstütze wirkende Stützkraft als Eingangsgröße eines Stellglieds in einem Regelkreis verwendet wird. Zusätzlich kann die auf die Dornstütze einwirkende Stützkraft als Eingangsgröße eines Stellglieds in einem Regelkreis verwendet werden, der zur Regelung der Planheit des Bandes dient. Regardless of whether the control is carried out as force control or position control, the target inclination and the target position of the mandrel support can be specified by a rotary encoder on the rotor. The regulations can alternatively take place depending on the position of the reel mandrel. In a variant of the method according to the invention it is provided that the supporting force acting on the mandrel support is used as an input variable of an actuator in a control loop. In addition, the supporting force acting on the mandrel support can be used as an input variable of an actuator in a control loop which serves to regulate the flatness of the band.

Die Erfindung wird nachstehend unter Bezugnahme auf die beigefügten Zeichnungen erläutert. In den Zeichnungen zeigen: The invention is explained below with reference to the accompanying drawings. The drawings show:

Die Figur 1 zeigt in stark vereinfachter und schematisierter Darstellung einen Wendehaspel 1. Der Wendehaspel umfasst einen Rotor 2, der beispielsweise als rotierende Scheibe ausgebildet sein kann, an welcher zwei Flaspeldorne 3 exzentrisch zu einer Drehachse D des Rotors 2 befestigt sind. Die beiden Flaspeldorne 3 erstrecken sich senkrecht zur Ebene des Rotors 2 und sind jeweils drehbar angetrieben. Der Wendehaspel 1 umfasst eine Dornstützeinrichtung 4 mit einer Dornstütze 5, an deren freien Ende sich ein gabelförmig ausgebildeter Lagerkopf 6 befindet. Die Dornstütze 5 ist Teil einer ersten Kolben-Zylinder-Anordnung 7 die hydraulisch längs verstellbar ist. In der dargestellten Stellung des Rotors 2 befindet sich der untere Haspeldorn 3 in der Anwickelposition A und der obere Haspeldorn 3 ist in der Fertigwickelposition F dargestellt. Der in der Anwickelposition A befindliche Haspeldorn 3 ist leer. Weiterhin ist in der Zeichnung die unterstützte Stellung des in Betrieb befindlichen Haspeldorns 3’ als Zwischenposition Z von einer Anwickelposition A in die Fertigwickelposition F dargestellt. Der in der Zwischenposition Z dargestellte Coil 8‘ ist bereits angewickelt. Der in der Fertigwickelposition F befindliche Haspeldorn 3 ist mit einem fertig gewickelten Coil 8 bestückt, wobei der Coil 8 in der Fertigwickelposition F als gestrichelte Linie angedeutet ist. Die Zwischenposition Z zeigt eine beliebige Position des Haspeldorns 3 mit einem beliebig stark aufgewickelten Band 9 bei seiner Überführung von der Anwickelposition A in die Fertigwickelposition F. Die Zwischenposition Z ist keine diskrete Stellung des Rotors 2. FIG. 1 shows a highly simplified and schematic illustration of a reversible reel 1. The reversible reel comprises a rotor 2, which can be designed, for example, as a rotating disk, to which two mandrel 3 are attached eccentrically to an axis of rotation D of the rotor 2. The two mandrel 3 extend perpendicular to the plane of the rotor 2 and are each rotatably driven. The reversible reel 1 comprises a mandrel support device 4 with a mandrel support 5, at the free end of which there is a fork-shaped bearing head 6. The mandrel support 5 is part of a first piston-cylinder arrangement 7 which is hydraulically longitudinally adjustable. In the position of the rotor 2 shown, the lower coiler mandrel 3 is in the winding position A and the upper coiler mandrel 3 is shown in the finished winding position F. The coiler mandrel 3 located in the winding position A is empty. Furthermore, the supported position of the reel mandrel 3 'in operation is shown in the drawing as an intermediate position Z from a winding position A to the finished winding position F. The coil 8 'shown in the intermediate position Z has already been wound up. The reel mandrel 3 in the finished winding position F is equipped with a completely wound coil 8, the coil 8 being indicated in the finished winding position F as a dashed line. The intermediate position Z shows an arbitrary position of the reel mandrel 3 with an arbitrarily strongly wound band 9 when it is transferred from the winding position A to the finished winding position F. The intermediate position Z is not a discrete position of the rotor 2.

Die Dornstütze 5 ist mittels einer zweiten Kolben-Zylinder-Anordnung 10 in ihrer Neigung verstellbar. Die Dornstütze 5 ist über ein Dornstützenlager 11 auf einem horizontal und auf einem ebenen Auflager 12 verfahrbaren Schlitten 13 gelagert. Der Schlitten 13 ist wiederum mittels einer dritten Kolben-Zylinder Anordnung 14 angetrieben bzw. verfahrbar. Durch eine Überlagerungsbewegung des tangential zu der Drehachse D des Rotors 2 verfahrbaren Schlittens 13 und der über die zweite Kolben-Zylinder Anordnung 10 bewirkten Winkelverstellung der Dornstütze 5, die wiederum als in der Länge verstellbare erste Kolben-Zylinder Anordnung 7 ausgebildet ist, kann der Lagerkopf 6 der Dornstütze 5 in Eingriff mit dem in Betrieb befindlichen Haspeldorn 3 der Kreisbahn des exzentrisch auf dem Rotor 2 gelagerten Haspeldorns von der Anwickelposition A über die Zwischenposition Z in die Fertigwickelposition F folgen, wobei, wie bereits vorstehend angemerkt, die Zwischenposition Z nur aus Gründen der Anschaulichkeit eingezeichnet ist. Diese Zwischenposition Z ist keine diskrete Stellung des Rotors 2. In der Anwickelposition A wird zunächst der Haspeldorn 3 angehoben, sodann wird das Band 9 auf den Haspeldorn 3 aufgewickelt. Nach etwa ein bis drei Wicklungen wird die Drehbewegung des Rotors 2 in Gang gesetzt. Der Rotor 2 dreht den in Betrieb befindlichen Haspeldorn 3 während dieser das Band 9 weiter aufgewickelt in die Fertigwickelposition F. In der Fertigwickelposition F wird ein stationäres Außenlager gegen den Haspeldorn 3 geschwenkt, sodass dieses den Haspeldorn 3 untergreift. Das stationäre Außenlager ist in den Zeichnungen nicht dargestellt. Der Lagerkopf 6 der Dornstütze 5 ist gabelförmig ausgebildet und untergreift den Haspeldorn nur auf einen Teilkreisabschnitt seines Umfangs. Ein Lagerkopf des stationären Außenlagers ist entsprechend ausgebildet und untergreift den Haspeldorn 3 ebenfalls nur auf einem Teilkreisumfang, derart, dass zunächst in der Fertigwickelposition F der Haspeldorn 3 auf demselben Längenabschnitt sowohl von dem Lagerkopf des stationären Außenlagers als auch von dem Lagerkopf 6 der Dornstütze 5 Untergriffen werden. Sobald der Haspeldorn auf dem stationären Außenlager abgestützt ist, wird der Lagerkopf 6 der Dornstütze 5 mit dem Haspeldorn 3 außer Eingriff gebracht, sodass die Dornstützeinrichtung in ihre Ausgangsposition zurückgefahren werden kann. Die erste, zweite und dritte Kolben-Zylinder-Anordnung 7, 10 und 13 ist jeweils mit Kraft- und/oder Wegsensoren versehen. Alternativ oder zusätzlich kann die erste Kolben - Zylinder - Anordnung 7 mit einem Winkelmesser/Neigungsmesser/Neigungssensor versehen sein. Erfindungsgemäß ist vorgesehen, die Dornstütze 5, die bereits in der Anwickelposition A mit dem freien Ende des Haspeldorns 3 in Eingriff gebracht wird, in Unterstützung des in Betrieb befindlichen Haspeldorns 3 mit einer entsprechenden Drehung des Rotors 2 mitzufahren bzw. nachzufahren. Zunächst hebt die Dornstütze 5 den leeren Haspeldorn 3 in der Anwickelposition A bereits so an, dass eine nicht wünschenswerte Durchbiegung bzw. Verbiegung kompensiert wird. Zur Regelung von Position und Neigung der Dornstütze 5 sind verschiedene Varianten möglich. Dabei werden beispielsweise die Neigung und die Position der Dornstütze 5 von einem nicht dargestellten Drehgeber am Rotor 2 als Sollwerte vorgegeben. Alternativ hierzu ist es möglich, die Soll - Neigung und die Soll -Position der Dornstütze 5 in Abhängigkeit der Lage des in Betrieb befindlichen Haspeldorns 3 vorzugeben. Alternativ oder zusätzlich kann die Soll-Neigung und die Soll-Position der Dornstütze 5 von einer Planheitsmessung des Bandes 9 vorgegeben werden. The mandrel support 5 can be adjusted in its inclination by means of a second piston-cylinder arrangement 10. The mandrel support 5 is supported via a mandrel support bearing 11 on a slide 13 which can be moved horizontally and on a flat support 12. The carriage 13 is in turn driven or moved by a third piston-cylinder arrangement 14. The bearing head can be adjusted by a superposition movement of the slide 13, which can be moved tangentially to the axis of rotation D of the rotor 2, and the angular adjustment of the mandrel support 5, which is in turn formed as a length-adjustable first piston-cylinder arrangement 7, by means of the second piston-cylinder arrangement 10 6 of the mandrel support 5 in engagement with the reel mandrel 3 in operation follow the circular path of the reel mandrel eccentrically mounted on the rotor 2 from the winding position A via the intermediate position Z into the finished winding position F, whereby, as already noted above, the intermediate position Z only for reasons for clarity. This intermediate position Z is not a discrete position of the rotor 2. In the winding position A, the reel mandrel 3 is first raised, then the band 9 is wound onto the reel mandrel 3. After about one to three windings, the rotary movement of the rotor 2 is started. The rotor 2 rotates the reel mandrel 3 in operation while it winds the tape 9 further into the finished winding position F. In the finished winding position F, a stationary outer bearing is pivoted against the reel mandrel 3 so that it grips under the reel mandrel 3. The stationary external bearing is not shown in the drawings. The bearing head 6 of the mandrel support 5 is fork-shaped and only engages under the coiler mandrel on a partial circular section of its circumference. A bearing head of the stationary outer bearing is designed accordingly and also engages under the reel mandrel 3 only on a partial circumference, such that, in the finished winding position F, the reel mandrel 3 on the same length section both from the bearing head of the stationary outer bearing and from the bearing head 6 of the mandrel support 5 engages become. As soon as the reel mandrel is supported on the stationary outer bearing, the bearing head 6 of the mandrel support 5 is disengaged from the reel mandrel 3, so that the mandrel support device can be moved back to its starting position. The first, second and third piston-cylinder arrangements 7, 10 and 13 are each provided with force and / or displacement sensors. Alternatively or additionally, the first piston-cylinder arrangement 7 can be provided with a protractor / inclinometer / inclinometer. According to the invention, the mandrel support 5, which is already brought into engagement with the free end of the reel mandrel 3 in the winding position A, is driven or traversed with the corresponding rotation of the rotor 2 in support of the reel mandrel 3 in operation. First, the mandrel support 5 already lifts the empty reel mandrel 3 in the winding position A in such a way that an undesirable deflection or bending is compensated for. Various variants are possible for regulating the position and inclination of the mandrel support 5. For example, the inclination and the position of the mandrel support 5 are specified as setpoints by an encoder (not shown) on the rotor 2. As an alternative to this, it is possible to specify the target inclination and the target position of the mandrel support 5 as a function of the position of the reel mandrel 3 in operation. Alternatively or additionally, the target inclination and the target position of the mandrel support 5 can be predetermined by a flatness measurement of the band 9.

Über eine Steuerung wird die entsprechende Soll - Position und Soll - Neigung der Dornstütze 5 angefahren. Der Neigungswinkel der Dornstütze 5 kann beispielsweise über eine Wegmessung im Zylinder der ersten Kolben-Zylinder- Anordnung 7 oder über eine Winkelmesseinrichtung erfasst werden. The corresponding target position and target inclination of the mandrel support 5 are approached via a control. The angle of inclination of the mandrel support 5 can be detected, for example, by measuring the distance in the cylinder of the first piston-cylinder arrangement 7 or using an angle measuring device.

Es kann eine reine Positionsregelung für die erste, zweite und dritte Kolben- Zylinder-Anordnung 7, 10, 14 vorgesehen sein. Die Kräfte aller Zylinder können mittels Kraftsensoren erfasst werden und mit den errechneten bzw. vorgegebenen Kräften verglichen werden. Alternativ ist es möglich, die erste und die zweite Kolben-Zylinder-Anordnung 7, 10 kraftgeregelt einzustellen, wohingegen die dritte Kolben-Zylinder Anordnung 14 über eine wegabhängige Regelung verfahren wird. A pure position control can be provided for the first, second and third piston-cylinder arrangements 7, 10, 14. The forces of all cylinders can be recorded using force sensors and compared with the calculated or specified forces. Alternatively, it is possible to set the first and the second piston-cylinder arrangement 7, 10 in a force-controlled manner, whereas the third piston-cylinder arrangement 14 is moved via a path-dependent control.

Die Kreisbahn der Haspeldorne 3, die diese mit dem Rotor 2 vollziehen, auf dem sie exzentrisch zur Drehachse D gelagert sind, ist mit dem Buchstaben K gekennzeichnet. Die Neigung der Dornstütze 5 wird während des Betriebs des unterstützten Haltedorns 3 so eingestellt, dass der Winkel zwischen der betreffenden Dornstütze 3 und einer Lotrechten weitestgehend dem Winkel zwischen einer resultierenden Kraft R aus einer Bandzugkraft BZ und der Gewichtskraft G des Coils 8, 8’entspricht. Eine grafische Kräftezerlegung der resultierenden Kraft R aus der Bandzugkraft BZ und der Gewichtskraft G des Coils 8,8' ist in Figur 2 dargestellt. The circular path of the coiler mandrels 3, which they perform with the rotor 2, on which they are mounted eccentrically to the axis of rotation D, is identified by the letter K. The inclination of the mandrel support 5 is adjusted during the operation of the supported holding mandrel 3 so that the angle between the mandrel support 3 in question and a vertical line largely corresponds to the angle between a resulting force R from a strip tensile force BZ and the weight G of the coil 8, 8 ′ . A graphic breakdown of forces resulting force R from the strip tensile force BZ and the weight G of the coil 8,8 'is shown in Figure 2.

Bei dem Verfahren gemäß der Erfindung wird, wie eingangs bereits erwähnt, der zu bestückende Haspeldorn 3 zunächst in die Anwickelposition A verbracht. In dieser Anwickelposition A wird das freie Ende des Haspeldorns 3 von der entsprechend verfahrenen Dornstütze 5 mit dem gabelförmig ausgebildeten Lagerkopf 6 unterfangen bzw. Untergriffen. Sodann hebt die Dornstütze 6 den Haspeldorn 3 in eine Lage an, in der einer durch Biegung bzw. Verbiegung des Haspeldorns 3 weitestgehend entgegengewirkt wird. In der Anwickelposition A werden zunächst zwei bis drei Windungen des Bandes 9 auf den Haspeldorn 3 aufgewickelt. Sodann wird der Rotor 2 des Wendehaspels 1 gemäß der Darstellung in Figuren 1 und 2 gegen den Uhrzeigersinn gedreht. Nach dem Anwickeln des Coils 8 wird über eine Drehung des Rotors 2 unter Beibehaltung der Bandzugkraft BZ der betreffende Haspeldorn 3 in die Fertigwickelposition F überführt. Bedingt durch den Wickelvorgang nimmt das Gewicht des Coils 8 stetig zu, der Winkel der resultierenden R aus Bandzugkraft BZ und Gewichtskraft G des Coils 8 ändert sich stetig. Die Stützkraft S der Dornstütze 5 wird beispielsweise mittels einer Regelung und Steuerung stets so angepasst, dass einer Durchbiegung der Dornstütze 3 jederzeit entsprechend entgegengewirkt wird. Wie vorstehend erwähnt ist die Regelung der Stützkraft S der Dornstütze 5 nur eine von mehreren Varianten zur Regelung der Position und Neigung der Dornstütze 5. Während der Drehbewegung des Rotors 2 werden die Neigung der Dornstütze 5 und die im Ausführungsbeispiel bezogen auf die Aufstellungsebene horizontale Lage des Schlittens 13 so eingestellt bzw. vorgegeben, dass die Neigung der Dornstütze 5 und mithin die Wirkungsrichtung der Stützkraft S im Wesentlichen entgegengesetzt der resultierenden R aus Bandzugkraft BZ und Gewichtskraft G des Coils 8 ausgerichtet ist. Die Dornstütze 5 ist also parallel zur Wirkrichtung der resultierenden R aus Bandzugkraft BZ und Gewichtskraft G ausgerichtet. Wie dies aus Figur 2 zu entnehmen ist, entspricht der Winkel a zwischen R und einer Lotrechten dem Winkel ß zwischen S und einer Lotrechten. Die Kraftregelung der Dornstütze 5 kann beispielsweise derart erfolgen, dass die Stützkraft S über den Zylinderdruck der ersten Kolben-Zylinder-Anordnung ermittelt wird. Alle Zylinder bzw. Kolben-Zylinder Anordnungen 7, 10, und 13 sind mit Wegaufnehmen versehen, mit denen die Position und Neigung der Dornstütze zuverlässig erfasst werden können. In the method according to the invention, as already mentioned at the beginning, the reel mandrel 3 to be fitted is first brought into the winding position A. In this winding position A, the free end of the reel mandrel 3 is underpinned or under-gripped by the correspondingly moved mandrel support 5 with the fork-shaped bearing head 6. Then the mandrel support 6 lifts the reel mandrel 3 into a position in which one is largely counteracted by bending or bending the reel mandrel 3. In the winding position A, two to three turns of the band 9 are first wound onto the reel mandrel 3. The rotor 2 of the turning reel 1 is then rotated counterclockwise as shown in FIGS. 1 and 2. After the winding of the coil 8, the reel mandrel 3 in question is transferred into the finished winding position F by rotating the rotor 2 while maintaining the strip tensile force BZ. Due to the winding process, the weight of the coil 8 increases steadily, the angle of the resulting R from the strip tensile force BZ and the weight G of the coil 8 changes continuously. The supporting force S of the mandrel support 5 is always adapted, for example by means of a regulation and control, in such a way that deflection of the mandrel support 3 is counteracted accordingly at any time. As mentioned above, the regulation of the supporting force S of the mandrel support 5 is only one of several variants for regulating the position and inclination of the mandrel support 5. During the rotary movement of the rotor 2, the inclination of the mandrel support 5 and the position of the horizontal position in relation to the installation plane of the embodiment Carriage 13 adjusted or predefined so that the inclination of the mandrel support 5 and thus the direction of action of the supporting force S is oriented essentially opposite to the resulting R from the strip tensile force BZ and the weight force G of the coil 8. The mandrel support 5 is thus aligned parallel to the effective direction of the resulting R from the belt tensile force BZ and the weight force G. As can be seen from FIG. 2, the angle a between R and a vertical corresponds to the angle β between S and a vertical. The force control of the mandrel support 5 can be carried out, for example, in such a way that the support force S is determined via the cylinder pressure of the first piston-cylinder arrangement. All cylinders or piston-cylinder arrangements 7, 10, and 13 are provided with displacement means with which the position and inclination of the mandrel support can be reliably detected.

Figur 3 zeigt eine Regelschema, in dem die Position des Haspeldorns 3 und die Durchbiegung des Haspeldorns 3 als Stellglied 15 in einem Regelkreis mit einem Regler 16 verwendet werden.

The control loop comprises a flatness measurement 19 of the belt 9, the measured values of which are processed in a flatness controller 20 together with the values from the actuator 15 '.
