Description

Technisches GebietTechnical area

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Wickeln einer Materialbahn, insbesondere eines Metallbandes, wobei ein Bund während des Wickelvorgangs durch zumindest zwei drehangetriebene Stützwalzen gestützt ist (siehe z.B. KR 1020040056824 A ).The invention relates to a method and an apparatus for winding a material web, in particular a metal strip, wherein a collar is supported during the winding process by at least two rotationally driven support rollers (see, for example KR 1020040056824 A ).

Stand der TechnikState of the art

In verschiedenen industriellen Herstellungsprozessen wird ein bandförmiges Material zu einer Wickelrolle aufgewickelt, bei der man eine möglichst gleichmäßige Kantendeckung anstrebt. Auch bei der Herstellung von metallischem Walzgut, wie beispielsweise einem Stahlband oder einem Aluminiumband, wird üblicherweise das aus einem Walzgerüst auslaufende Walzband zu einem Bund gewickelt.In various industrial manufacturing processes, a band-shaped material is wound into a winding roll, in which one strives for the most uniform possible edge coverage. Also in the production of metallic rolling stock, such as a steel strip or an aluminum strip, usually the rolling strip running out of a rolling mill is wound into a bundle.

Um die Qualität eines Metallbandes prüfen zu können, wird ein Probenstück des Metallbundes einer Inspektion unterzogen. Hierfür wird vom Bund ein Stück des Walzbandes abgewickelt und nach der Kontrolle wieder zurück gewickelt. Dabei tritt das Problem auf, dass mit zunehmender Abwickellänge die Gefahr besteht, dass das Walzband seitlich verläuft. Folge davon ist dann ein zumindest an den äußeren Windungen teleskopierter Metallbund. Von der Stirnfläche des Metallbundes überstehendes Metallband kann dann leicht beim Transport in nachfolgenden Prozessschritten beschädigt werden. Insgesamt kann der Metallbund dadurch in seinem Wert gemindert sein.In order to be able to test the quality of a metal strip, a sample of the metal strip is subjected to an inspection. For this purpose, a piece of the rolled strip is unwound by the Federal Government and wound back after checking. The problem arises that with increasing unwinding length there is a risk that the rolled strip runs laterally. The consequence of this is then a metal collar telescoped at least on the outer turns. From the end face of the metal collar protruding metal band can then be easily damaged during transport in subsequent process steps. Overall, the metal collar can be reduced in its value.

Um dieses Problem des seitlichen Verlaufens zu vermeiden, könnte man beispielsweise die Abwickellänge begrenzen, oder aber man schneidet ein Probenstück ab. Ersteres hat den Nachteil, dass die Inspektion nicht in der gewünschten Länge durchgeführt werden kann. Letzteres verursacht Ausschussmaterial, da das abgeschnittene Probenstück weggeworfen wird.To avoid this problem of lateral bleeding, one could for example limit the unwinding length, or but one cuts off a sample piece. The former has the disadvantage that the inspection can not be performed in the desired length. The latter causes scrap material because the cut sample is discarded.

Darstellung der ErfindungPresentation of the invention

Es ist eine Aufgabe der vorliegenden Erfindung, ein Verfahren und eine Vorrichtung zum Wickeln einer bandförmigen Materialbahn anzugeben, so dass ein seitliches Verlaufen beim Aufwickeln möglichst verhindert ist.It is an object of the present invention to provide a method and an apparatus for winding a band-shaped material web, so that lateral running during winding is as far as possible prevented.

Diese Aufgabe wird für eine Vorrichtung gemäß den Merkmalen des Anspruchs 1, und für ein Verfahren, gemäß den Merkmalen des Anspruchs 4 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den jeweils abhängigen Ansprüchen definiert.This object is achieved for a device according to the features of claim 1, and for a method according to the features of claim 4. Advantageous embodiments of the invention are defined in the respective dependent claims.

Gemäß einem Grundgedanken der Erfindung wird die an den Stützrollen aufliegende Gewichtskraft des Bundes durch die Neigung von Stützwalzen oder Bodenwalzen eine horizontale Kraftkomponente erzeugt, die dazu genutzt wird, um dem seitlichen Verlaufen einer Materialbahn entgegenzuwirken. Dies wird dadurch erreicht, indem mittels einer Schwenkeinrichtung die zwei oder auch mehrere Stützwalzen gemeinsam um eine Schwenkachse zwischen einer ersten, im Wesentlichen horizontalen Stellung, in eine zweite, bezüglich der horizontalen Stellung geneigte Stellung, geschwenkt. Mit anderen Worten, indem die Achsen der Stützrollen gegenläufig zum seitlichen Verlaufen des Bandes bezüglich der Horizontalen geneigt werden können, kann man beim (Zurück-) Wickeln eines Metallbandes die Kantendeckung am Bund aufrecht erhalten. Läuft beispielsweise die Kante einer Materialbahn von der Stirnfläche des Bundes heraus, werden die beiden Stützrollen so geneigt, dass die Bahnkante wieder zurück zur Stirnfläche kommt. Die Neigung der Stützrollen kann dabei so vonstatten gehen, dass eine Stirnseite bezüglich der Horizontalen abgesenkt wird, je nachdem, auf welcher Seite die Bahnkante von der Stirnfläche heraus läuft. Die Neigung der Stützrollen kann aber auch so erfolgen, dass ähnlich einem Waagebalken eine Stirnseite des Bundes gesenkt und gleichzeitig die andere angehoben wird. Der Schwenkvorgang kann im einfachsten Fall manuell gesteuert sein, indem beispielsweise von einem Betriebspersonal der Vorgang beim Zurückwickeln des Metallbandes beobachtet wird. Wird visuell ein seitliches Verlaufen des Metallbandes erkannt, so wird über eine Bedieneinrichtung von Hand eine entsprechende Neigebewegung ausgelöst. In der Walzwerktechnik kann ein Metallbund, ein so genannter Coil, beispielsweise 40 t schwer sein. Um dieses Schwergewicht zu neigen, ist eine entsprechend eingerichtete Antriebsvorrichtung erforderlich, welche die erforderliche Kraft für die Schwenkbewegung aufzubringen vermag. Diese Krafterzeugung kann beispielsweise durch eine oder mehrere hydraulische Kolben-ZylinderEinheiten, oder durch einen Elektroantrieb in Verbindung mit einer Spindel erfolgen. Es sei aber bereits an dieser Stelle erwähnt, dass die Steuerung der Achsneigung auch durch eine automatisch arbeitende Vorrichtung erfolgen kann. Die Gewichtskraft eines Metallbundes, wird sehr effizient dazu genutzt, um eine horizontale, dem Bandverlauf entgegen gerichtete Kraftkomponente zu erzeugen. Durch die erfindungsgemäße Achsneigung der Stützrollen wird erreicht, dass nach der Inspektion eines Metallbundes die Stirnflächen eben sind. Damit gibt es keine überstehenden Ränder, die in nachfolgenden Prozessschritten oder in einem anschließenden Transport des Metallbundes beschädigt werden könnten. Der wesentliche Vorteil der Erfindung ist also darin zu sehen, dass der Wert des Metallbundes durch beziehungsweise nach einer Inspektion nicht gemindert wird. Ein weiterer Kostenvorteil der Erfindung liegt darin, dass bei der Inspektion kein Stück des Metallbandes abgeschnitten und verworfen werden muss. Dadurch fällt bei der Inspektion kein Schrott mehr an. Die technische Realisierung einer Schwenkvorrichtung zum Neigen der Drehachsen der Stützrollen kann vergleichsweise einfach und weitgehend durch bekannte kommerziell erhältliche Baueinheiten mit relativ geringen Kosten realisiert werden.According to a basic idea of the invention, the weight force of the collar resting on the support rollers is generated by the inclination of support rollers or bottom rollers, a horizontal force component which is used to counteract the lateral running of a material web. This is achieved by pivoting by means of a pivoting device, the two or more support rollers together about a pivot axis between a first, substantially horizontal position, in a second, with respect to the horizontal position inclined position. In other words, by the axes of the support rollers can be inclined in opposite directions to the lateral extent of the band with respect to the horizontal, one can maintain the edge coverage at the waistband when (re) winding a metal strip. If, for example, the edge of a material web runs out from the end face of the collar, the two support rollers are inclined so that the web edge comes back to the end face. The inclination of the support rollers can do so It will be understood that one end face is lowered with respect to the horizontal, depending on which side the web edge is running from the end face. But the inclination of the support rollers can also be done so that similar to a balance beam one end of the collar lowered and at the same time the other is raised. The pivoting operation can be controlled manually in the simplest case, for example, by an operating staff watching the process when rewinding the metal strip. If visually a lateral bleeding of the metal strip is detected, then a corresponding tilting movement is triggered by an operating device by hand. In rolling mill technology, a metal collar, a so-called coil, can be for example 40 tons. To tilt this heavy weight, a correspondingly configured drive device is required, which is able to apply the force required for the pivoting movement. This power generation can be done for example by one or more hydraulic piston-cylinder units, or by an electric drive in conjunction with a spindle. However, it should already be mentioned at this point that the control of the axial tilt can also be done by an automatically operating device. The weight of a metal collar is used very efficiently to produce a horizontal force component directed counter to the strip. Due to the axial inclination of the support rollers according to the invention it is achieved that after the inspection of a metal collar, the end faces are flat. Thus, there are no protruding edges that could be damaged in subsequent process steps or in a subsequent transport of Metallbundes. The essential advantage of the invention is thus to be seen in the fact that the value of the metal collar is not reduced by or after an inspection. Another cost advantage of the invention is that during inspection no piece of the metal strip has to be cut off and discarded. As a result, no more scrap is generated during the inspection. The technical realization of a pivoting device for tilting the axes of rotation of the support rollers can be relatively easily and largely realized by known commercially available units with relatively low cost.

Gemäß der Erfindung weist die Schwenkeinrichtung eine spezielle Stützvorrichtung auf, in welcher die zumindest zwei drehangetriebenen Stützwalzen drehbar gelagert sind. Die Stützvorrichtung kann beispielsweise ein Metallrahmen sein der nach Art eines Waagebalkens ausgebildet ist, das heißt der Rahmen ist bezüglich einer Schwenkachse schwenkbar, beispielsweise indem er mittig abgestützt ist. In diesem Fall verläuft die Schwenkachse durch den Querbalken des Rahmens. Es ist aber auch möglich, dass der Rahmen so konstruiert ist, dass räumlich gesehen, die Drehachsen der Stützrollen und die Schwenkachse einander sich kreuzen, aber nicht schneiden.According to the invention, the pivoting device on a special support device in which the at least two rotationally driven support rollers are rotatably mounted. The support device may for example be a metal frame which is designed in the manner of a balance beam, that is, the frame is pivotable relative to a pivot axis, for example by being centrally supported. In this case, the pivot axis passes through the crossbar of the frame. But it is also possible that the frame is constructed so that spatially seen, the axes of rotation of the support rollers and the pivot axis intersect each other, but do not intersect.

In einer bevorzugten Ausführungsform der Vorrichtung, beziehungsweise des Verfahrens, ist vorgesehen, dass die Stützwalzen jeweils um einen Schwenkwinkel schwenkbar sind, der stufenlos vorgebbar ist. Dadurch kann sehr differenziert einem Verlaufen der Materialbahn entgegengewirkt werden. Auch hier wird die Gewichtskraft dazu verwendet, um ein seitliches Verlaufen des bandförmigen Materials zu verhindern. Verglichen mit einem seitlichen Verschieben der Stützrollen benötigt der Schwenkvorgang weniger Energie.In a preferred embodiment of the device, or the method, it is provided that the support rollers are each pivotable about a pivot angle, which is infinitely predetermined. This can be counteracted a very differentiated a bleeding of the material web. Again, the weight is used to prevent lateral bleeding of the band-shaped material. Compared to a lateral displacement of the support rollers, the pivoting process requires less energy.

Es kann günstig sein, wenn die Schwenkbewegung eine Absenkbewegung ist, das heißt wenn die durch die Schwenkbewegung der Drehachsen der Stützwalzen jeweils aufgespannte Schwenkebene lotrecht verläuft.It may be favorable if the pivoting movement is a lowering movement, that is to say if the pivoting plane respectively spanned by the pivoting movement of the axes of rotation of the supporting rollers is perpendicular.

Um wie bereits oben angedeutet, die Schwenkbewegung automatisch durchführen zu können, kann vorgesehen sein, dass die Kante der auf den Bund zulaufenden Materialbahn mittels eines geeigneten Sensors erfasst wird. Ein solcher Bahnkantensensor kann nach unterschiedlichen Messprinzipien arbeiten, beispielsweise taktil oder berührungslos, z.B. ein Ultraschallsensor oder ein optisch arbeitendes System sein. Der Bahnkantensensor liefert dabei eine Lageinformation, die der Schwenkeinrichtung zugeleitet ist. Bei der Vorgabe des Schwenkwinkels wird diese Lageinformation entsprechend berücksichtigt. Die technische Ausführung einer solchen Schwenkeinrichtung beinhaltet im Wesentlichen eine Informationsverarbeitende Einheit, z.B. ein Computer, der über entsprechende Steuersignale eine Antriebseinrichtung zum Erzeugen der Schwenkbewegung veranlasst. Beides ist im Grunde nach kommerziell verfügbar, kann mit geringem Aufwand entsprechend angepasst verwendet und braucht daher hier im Detail nicht näher erläutert zu werden.In order, as already indicated above, to be able to carry out the pivoting movement automatically, it can be provided that the edge of the material web running onto the bundle is detected by means of a suitable sensor. Such a web edge sensor can operate according to different measuring principles, for example tactile or non-contact, for example a Ultrasonic sensor or an optically operating system. The web edge sensor supplies a position information that is fed to the pivoting device. When specifying the swivel angle, this position information is considered accordingly. The technical design of such a pivoting device essentially comprises an information processing unit, for example a computer, which causes a drive device for generating the pivoting movement via corresponding control signals. Both are basically commercially available, can be used appropriately adjusted with little effort and therefore need not be explained in detail here in detail.

Ausführung der ErfindungEmbodiment of the invention

Die Figur 1 und die Figur 2 zeigen in einer schematischen Darstellung das Prinzip der vorliegenden Erfindung. Dargestellt ist die Situation eines Bundes 1, der auf zwei Stütz- oder Bodenrollen 2, 3 aufliegt. Ein solcher Bund kann beispielsweise ein Metallbund sein. Es sei davon ausgegangen, dass zum Zwecke der Inspektion zuvor ein Stück von einer Materialbahn 14, im folgenden auch Metallband, Walzband oder Walzgut genannt, abgewickelt und nun wieder zurück gewickelt werden soll. Ein Drehantrieb 7 versetzt die beiden Rollen 2, 3 in eine Drehbewegung. Das Metallband 14 läuft also in Richtung der Bandlaufrichtung 10 auf den sich drehenden Metallbund 1 zu. Dabei kann es wie eingangs dargestellt, zu einem unerwünschten seitlichen Verlaufen des Metallbandes 14 kommen. Folge davon ist ein Teleskopieren des Metallbundes 1, was unerwünscht ist, da überstehende Kanten entstehen, die beschädigt werden können und den Wert des Metallbundes beeinträchtigen können.The FIG. 1 and the FIG. 2 show in a schematic representation of the principle of the present invention. Shown is the situation of a covenant 1, which rests on two support or floor rolls 2, 3. Such a collar may for example be a metal collar. Let it be assumed that, for the purpose of inspection, a piece of a material web 14, hereinafter also referred to as a metal strip, rolled strip or rolling stock, should first be unwound and then wound back again. A rotary drive 7 sets the two rollers 2, 3 in a rotary motion. The metal strip 14 thus runs in the direction of the strip running direction 10 toward the rotating metal collar 1. It may, as shown initially, come to an undesirable lateral bleeding of the metal strip 14. The result is a telescoping of the metal collar 1, which is undesirable because protruding edges arise that can be damaged and affect the value of the metal collar.

Eine Lenkung der zum Bund 1 zulaufenden Materialbahn 14 kann dies verhindern. Erfindungsgemäß erfolgt diese Bandlenkung so, dass die Stütz- oder Bodenrollen 2 und 3, die für den Metallbund 1 eine so genannte "Wickelmulde" oder ein "Wickelbett" bilden, kopfseitig oder fußseitig abgesenkt oder angehoben werden. Durch diese Korrektur kann eine sehr gute Kantendeckung des Metallbundes 1 erreicht werden. Wie unten noch näher ausgeführt, kann die Bandlenkung grundsätzlich manuell oder auch automatisch gesteuert sein.A steering of the collar 1 tapered web 14 can prevent this. According to the invention, this band deflection is carried out so that the support or bottom rollers 2 and 3, which form a so-called "winding trough" or a "winding bed" for the metal collar 1, are lowered or raised on the head or foot side. By this correction, a very good edge coverage of the metal collar 1 can be achieved. As below Executed in more detail, the band steering can be basically controlled manually or automatically.

Kommt es beispielsweise zu einem seitlichen Verlaufen des Walzbandes 14, entweder in Richtung A, oder B, so wird das Eigengewicht des Bundes dazu genutzt, die Bandlaufkorrektur durchzuführen. Dies funktioniert so, in dem die "Wickelmulde" oder das "Wickelbett", mittels einer Schwenkeinrichtung 11 geschwenkt wird, das heißt an einer Seite abgesenkt oder angehoben wird. Dies ist durch die Doppelpfeile D und C in den Figuren 1 und 2 angedeutet. Dabei wird jede Drehachse 5, 6 um den Schwenkwinkel 12 geschwenkt. Dies hat zur Folge, dass auch die Bundachse 8 geneigt wird. In Figur 1 zeigt der Pfeil 9 eine nach linksgerichtete Bewegung des Metallbundes 1, die durch das Eigengewicht des Metallbundes 1 verursacht wird, in dem zuvor die linke Lagerseite der Stützrollen 2, 3 entsprechend dem Pfeil D nach unten abgesenkt wurde.If, for example, there is a lateral running of the rolled strip 14, either in the direction A or B, then the self-weight of the collar is used to carry out the strip running correction. This works so, in which the "winding trough" or the "winding bed" is pivoted by means of a pivoting device 11, that is lowered or raised on one side. This is indicated by the double arrows D and C in the Figures 1 and 2 indicated. In this case, each axis of rotation 5, 6 is pivoted about the pivot angle 12. This has the consequence that the collar axis 8 is inclined. In FIG. 1 shows the arrow 9 a leftward movement of the metal collar 1, which is caused by the weight of the metal collar 1, in the previously the left bearing side of the support rollers 2, 3 was lowered according to the arrow D down.

Die Kraft für die Schwenkbewegung in Richtung des Pfeils D kann auf verschiedene Weise beispielsweise hydraulisch oder elektrisch erzeugt werden.The force for the pivoting movement in the direction of the arrow D can be generated in various ways, for example hydraulically or electrically.

Verläuft in einem anderen Beispiel das Walzband 14 in Richtung A des Doppelpfeils AB, so werden die beide Stützrollen 2, 3 in Richtung des Pfeils C nach unten abgesenkt. (Umgekehrt, bei einem Bandverlauf in Richtung B, werden die Stützrollen 2, 3 in Richtung des Pfeils D nach unten geschwenkt.)Runs in another example, the rolled strip 14 in the direction A of the double arrow AB, the two support rollers 2, 3 are lowered in the direction of arrow C down. (Conversely, in a belt run in the direction B, the support rollers 2, 3 are pivoted in the direction of the arrow D down.)

Die in Korrekturfall erforderliche links- oder rechtsseitige Absenk-Bewegung führt im Ergebnis dazu, dass wieder eine gute Kantendeckung an den Stirnflächen des Metallbundes 1 erreicht werden kann. Bei der Herstellung eines Walzbandes 14 ist also nach der Inspektion, bei der ein Stück des Walzgutes 14 abgewickelt und anschließend nach der Inspektion wieder zurück auf den Metallbund 1 gewickelt werden muss, nicht mehr teleskopartig verschoben. Es gibt daher keine überstehenden Bahnkanten des Walzgutes, die bei der weiteren Handhabung des Metallbundes 1 beschädigt werden könnten.As a result, the left or right-side lowering movement required in the event of correction results in that a good edge coverage at the end faces of the metal collar 1 can again be achieved. In the production of a rolled strip 14 is thus after the inspection, in which a piece of the rolling stock 14 unwound and then after the inspection must be wound back on the metal collar 1, no longer telescoped. There are therefore no outstanding ones Web edges of the rolling stock, which could be damaged in the further handling of the metal collar 1.

Wenn bei einem (Zurück-) Wickelvorgang die Bahnkante der Materialbahn 14 nicht verläuft, so wird im Wesentlichen die waagerechte Ausrichtung der Stützwalzen 2, 3 beibehalten, denn es besteht kein Grund für eine Korrektur oder Lenkung.If during a (re) winding process, the web edge of the material web 14 is not running, so the horizontal orientation of the support rollers 2, 3 is maintained substantially, because there is no reason for a correction or steering.

Die Drehachsen 5, 6 der beiden Stützrollen 2, 3 verlaufen im vorliegenden Beispiel parallel zueinander und liegen in einer horizontalen Ebene. Die einseitige Absenk-Bewegung der Stützrollen-Achsen 5, 6 erfolgt im vorliegenden Ausführungsbeispiel synchron, das heißt der pro Zeiteinheit überstrichene Schwenkwinkel ist für beide Stützrollen 2, 3 gleich groß.The axes of rotation 5, 6 of the two support rollers 2, 3 in the present example are parallel to one another and lie in a horizontal plane. The unilateral lowering movement of the support roller axes 5, 6 takes place synchronously in the present embodiment, that is, the swept per unit time pivot angle is the same for both support rollers 2, 3.

Wie bereits gesagt, kann die Lenkung des Walzbandes manuell oder auch automatisch gesteuert sein. In den Zeichnungen der Figur 1 und Figur 2 ist eine automatische Bandlenkung durch einen Bahnkantensensor 4 angedeutet, dessen Sensorsignal 13 der Schwenkeinrichtung 11 zugeleitet ist. Die Schwenkeinrichtung 11 beinhaltet eine entsprechende Signalverarbeitung. Diese verwendet das Sensorsignal 13 als Stellsignal für eine in Figur 1 und 2 nicht näher dargestellte Antriebseinrichtung.As already mentioned, the steering of the rolled strip can be controlled manually or automatically. In the drawings of the FIG. 1 and FIG. 2 an automatic strip deflection is indicated by a web edge sensor 4, the sensor signal 13 of the pivoting device 11 is fed. The pivoting device 11 includes a corresponding signal processing. This uses the sensor signal 13 as a control signal for a in FIGS. 1 and 2 not shown drive device.

Figur 3 zeigt eine mögliche Ausführungsform der Erfindung, bei der die Drehachsen 5, 6 der Stützwalzen 2, 3 in einem als Waagebalken ausgebildeten Stützvorrichtung 16 jeweils endseitig in einem Rahmenteil drehbar gelagert sind. Der Rahmenteil 16 ist um eine Schwenkachse 18 drehbar. Erzeugt wird diese Bewegung mittels eines Schwenkantriebs 15, im vorliegenden Beispiel einer Kolben-Zylinder-Einheit die rechts am Rahmenteil 16 angreift und an dieser Seite entweder nach oben oder nach unten bewegt. Durch diese Schwenkbewegung bei der sich die beiden Drehachsen 5, 6 in eine Position 5', 6' beziehungsweise 5", 6" verlagern, entsteht für den Metallbund 1 je nach Blickrichtung ein ansteigendes oder abschüssiges Terrain. Die Bundachse 8 verläuft parallel zur Neigung der Drehachsen 5', 6' beziehungsweise 5", 6". Seiner Schwerkraft folgend wird der Bund 1 der abschüssigen Seite folgen, wodurch sein Eigengewicht bei der Lenkung des Metallbandes 14 ausgenützt und einem seitlichen Verlaufen auf effiziente Weise entgegengewirkt werden kann. FIG. 3 shows a possible embodiment of the invention, in which the axes of rotation 5, 6 of the support rollers 2, 3 are rotatably mounted in a frame member in each case end side in a support device 16 designed as a balance beam. The frame part 16 is rotatable about a pivot axis 18. This movement is produced by means of a pivoting drive 15, in the present example a piston-cylinder unit which acts on the right on the frame part 16 and moves either upwards or downwards on this side. By this pivotal movement in which the two axes of rotation 5, 6 in a position 5 ', 6' and 5 ", 6" relocate, arises for the metal collar 1 depending on the direction of a rising or sloping terrain. The collar axis 8 runs parallel to the inclination of the axes of rotation 5 ', 6' or 5 ", 6". Following its gravity, the collar 1 will follow the sloping side, whereby its own weight in the steering of the metal strip 14 can be exploited and a lateral bleeding can be counteracted in an efficient manner.

Die konstruktive Ausbildung der Schwenkvorrichtung 11, wie im Wesentlichen aus dem Rahmenteil 16 und der Antriebseinheit 15 besteht, braucht hier nicht näher eingegangen zu werden, da diese Baueinheiten als bekannt beziehungsweise kommerziell erhältlich vorausgesetzt werden können. Es sei auch hier nochmals darauf hingewiesen, dass die Schwenkeinrichtung 11 sowohl manuell als auch automatisch betrieben werden kann.The structural design of the pivoting device 11, as consists essentially of the frame part 16 and the drive unit 15, need not be discussed here in detail, since these units can be assumed to be known or commercially available. It should also be noted again that the pivoting device 11 can be operated both manually and automatically.

In der Ausführung gemäß der Figur 3 liegt die Schwenkachse 18 symmetrisch auf der Linie einer Symmetrieachse 17, die einen Mittelbereich der Wickelvorrichtung kennzeichnet. Wie unten ausgeführt, ist dies aber nicht zwingend erforderlich.In the execution according to the FIG. 3 the pivot axis 18 is symmetrical on the line of an axis of symmetry 17, which marks a central region of the winding device. As explained below, this is not absolutely necessary.

Die Figur 4 veranschaulicht dies nochmals in einer räumlichen Darstellung. Die Schwenkbewegung gemäß dem Pfeil 19 um den Schwenkwinkel 12 erfolgt in einer senkrechten Schwenkebene 50 beziehungsweise 60.The FIG. 4 illustrates this again in a spatial representation. The pivoting movement according to the arrow 19 about the pivot angle 12 takes place in a vertical pivot plane 50 and 60, respectively.

Die Figur 5 zeigt die Anordnung der beiden Drehachsen 5, 6 bezüglich der Schwenkachse 18 gemäß dem Ausführungsbeispiel der Figur 4. Die Schwenkachse 18 schneidet nicht die beiden Drehachsen 5, 6, sondern liegt in einem senkrechten Abstand davon entfernt. Mit dem Doppelpfeil 19 ist wieder die Schwenkbewegung angedeutet, wodurch die Achseneigung zwischen der Position 5', 6' beziehungsweise 5", 6" stufenlos verstellbar ist.The FIG. 5 shows the arrangement of the two axes of rotation 5, 6 with respect to the pivot axis 18 according to the embodiment of FIG. 4 , The pivot axis 18 does not intersect the two axes of rotation 5, 6, but is located at a vertical distance therefrom. With the double arrow 19, the pivoting movement is again indicated, whereby the axis inclination between the position 5 ', 6' and 5 ", 6" is infinitely adjustable.

Anders als in Figur 5 zeigt die Skizze in Figur 6 ein anderes mögliches Ausführungsbeispiel, bei dem die Schwenkachse 18 die Drehachsen 5, 6 schneidet. Auch hier ist wieder jede der beiden Drehachsen 5, 6 zwischen der Position 5', 6' beziehungsweise 5", 6" stufenlos verstellbar.Unlike in FIG. 5 shows the sketch in FIG. 6 another possible embodiment in which the pivot axis 18, the axes of rotation 5, 6 intersects. Again, every one of them is here both axes of rotation 5, 6 between the position 5 ', 6' and 5 ", 6" continuously adjustable.

In den oben gezeigten Beispielen, liegen die beiden Drehachsen 5, 6 parallel zueinander und verlaufen etwa in einer horizontal liegenden Ebene. Dies ist aber nicht zwingend erforderlich. Es erscheint auch möglich, dass die beiden Drehachsen 5, 6 zwar parallel zueinander verlaufen, aber bezüglich der Schwenkachse 18 einen unterschiedlichen Abstand haben.In the examples shown above, the two axes of rotation 5, 6 are parallel to each other and extend approximately in a horizontal plane. But this is not mandatory. It also seems possible that the two axes of rotation 5, 6, although parallel to each other, but with respect to the pivot axis 18 have a different distance.

Die Schwenkbewegung kann so erfolgen, dass die gegenüberliegende Stirnseite abgesenkt oder angehoben wird. Die Schwenkbewegung kann aber auch gemäß einem Waagebalkens das Absenken der einen Seite, ein anheben der anderen Seite bewirkt.The pivoting movement can be carried out so that the opposite end side is lowered or raised. However, the pivoting movement can also according to a balance beam lowering one side, raising the other side causes.

Im Falle einer automatischen Steuerung der Stützrollen kann die dafür erforderliche Erfassung der Bahnkante auf unterschiedliche Weise realisiert sein, beispielsweise berührend oder berührungslos.In the case of automatic control of the support rollers, the required detection of the web edge can be realized in different ways, for example, touching or non-contact.

Obwohl die Erfindung in Detail durch das bevorzugte Ausführungsbeispiel näher illustriert und beschrieben wurde, so ist die Erfindung nicht durch die offenbarten Beispiele eingeschränkt und andere Variationen können vom Fachmann hieraus abgeleitet werden, ohne den Schutzumfang der Erfindung zu verlassen.Although the invention has been further illustrated and described in detail by the preferred embodiment, the invention is not limited by the disclosed examples and other variations can be derived therefrom by those skilled in the art without departing from the scope of the invention.

So kann die Schwenkeinrichtung 11 auf unterschiedliche Art und Weise ausgebildet sein, z.B. ein Hydraulikantrieb und/oder ein Elektroantrieb. Die Absenkbewegung kann mittels Spindel oder mit einem anderen Getriebe realisiert sein. Selbst verständlich können anstelle der hier dargestellten Stützung mittels zweier Stützrollen auch mehrere Stützrollen verwendet werden. Der Antrieb des Schwenkrahmens kann selbstverständlich auch durch mehrere Linearantriebe, die jeweils endseitig im Bereich der Lager der Stützrollen angreifen, realisiert sein. Es ist auch denkbar, dass die Schwenkbewegung durch einen Drehantrieb erzeugt wird.Thus, the pivoting device 11 may be formed in different ways, such as a hydraulic drive and / or an electric drive. The lowering movement can be realized by means of a spindle or with another gear. Of course, instead of the support shown here by means of two support rollers and several support rollers can be used. The drive of the swing frame can of course also by several linear drives, each end in the area of the bearings of the support rollers attack, be realized. It is also conceivable that the pivoting movement is generated by a rotary drive.

Wie in den vorangegangenen Erläuterungen der Beispiele hervorgehoben, besteht ein bevorzugtes Anwendungsgebiet der Erfindung beim Wickeln eines Metallbandes, insbesondere bei der Inspektion oder Probennahme.As pointed out in the preceding explanations of the examples, a preferred field of application of the invention is the winding of a metal strip, in particular during inspection or sampling.

Selbst verständlich ist die Erfindung aber nicht auf dieses Anwendungsbeispiel des Zurückwickelns eines Metallbandes eingeschränkt, sondern grundsätzlich für den Wickelvorgang einer beliebigen Materialbahn, wie beispielsweise einer Kunststoffbahn oder einer Papierbahn oder einer Bahn aus Textilstoff oder einem anderen Werkstoff anwendbar.Of course, the invention is not limited to this application example of rewinding a metal strip, but in principle applicable for the winding process of any material web, such as a plastic web or a paper web or a web of fabric or other material.
