Description

Haspelvorrichtung für WalzbandCoiler device for rolled strip
Die Erfindung betrifft eine Haspelvorrichtung für ein Walzband, umfassend wenigstens eine antreibbare Muldenrolle zum Drehen eines Coils beim Auf- oder Abhaspeln eines Walzbandes sowie mit einem dem Haspel vor- oder nachge- ordneten Rollgang.The invention relates to a reel device for a rolled strip, comprising at least one drivable trough roller for rotating a coil when winding or unwinding a rolled strip and with a roller table upstream or downstream of the reel.
Haspelvorrichtungen mit Muldenrollen sind überlicherweise im Auslaufteil einer Warmbreitband, bzw. beim Warmbandtransport eingesetzt. Die Muldenrolle hat die Aufgabe, mit ihrem Antrieb das Coil zu drehen und einer Schere die rechtwinklig neben dem Bundtransport angeordnet ist, das Walzband vorzutreiben. An der Schere wird das Coil geschöpft und es werden Proben aus dem Walzband geschnitten.Coiler devices with trough rollers are usually used in the outlet section of a hot wide strip, or during hot strip transport. The purpose of the trough roller is to turn the coil with its drive and to advance the rolled strip using a pair of scissors that are arranged at right angles next to the coil transport. The coil is scooped on the scissors and samples are cut from the rolled strip.
Beim Stand der Technik bisher eingesetzte Muldenrollen sind mit festen Durchmessermaßen ausgebildet und für eine angenäherte Radius-Anpassung mit einer hohlgefertigten Kontaktfläche für das Coil ausgebildet. Beim Drehen balliger Coils führt das zu Markierungen am Coilumfang infolge Linienberüh- rungs-Walzeffekte. Auch sind die bekannten Ausführungen von Muldenrollen durch Ihre Abmaße sehr steif und lassen keine Durchbiegung der Rolle zu.Trough rollers previously used in the prior art are designed with fixed diameters and for an approximate radius adjustment with a hollow contact surface for the coil. When turning spherical coils, this leads to markings on the coil circumference as a result of line contact rolling effects. The well-known versions of trough rollers are also very stiff due to their dimensions and do not allow the roller to bend.
Das Dokument DE-OS 24 127 47 beschreibt eine Abzieh- und Richtanlagen für Bunde warmgewalzter Bleche mit einem Auflagerrollenpaar für die Blechbunde und eine Haltevorrichtung für das Blechende, mit der das Blech über eine Ge- genbiegerolle abziehbar ist.The document DE-OS 24 127 47 describes a stripping and straightening system for bundles of hot-rolled sheets with a pair of support rollers for the sheet bundles and a holding device for the sheet end, with which the sheet can be pulled off via a counter-bending roller.
Die beiden Auflagerrollen und ein zwischen diesen angeordneter Hubtisch sind auf einem verfahrbaren Bundwagen montiert. Der Bundwagen ist mit einem gegenüber der ortsfesten Haltevorrichtung verschiebbaren Abziehwagen kuppelbar. Der Abziehwagen trägt eine zusätzliche antreibbare Auflagerrolle, die mit der ihr näher liegenden Auflagerrollen des Bundwagens ein weiteres Auflagerrollenpaar bildet. Auf beiden Wagen vor bzw. hinter den Auflagerrollen sind je eine in ihrer Lage verstellbare Stützrolle vorgesehen, von denen die am Ab- ziehwagen gelagerte auch als Gegenbiegerolle dient.The two support rollers and a lifting table arranged between them are mounted on a movable coil carriage. The carriage is with one puller carriage that can be coupled relative to the stationary holding device. The puller wagon carries an additional drivable support roller, which forms a further pair of support rollers with the support rollers of the coil carriage closer to it. On both carriages in front of and behind the support rollers there is provided a support roller which is adjustable in its position, of which the one supported on the pulling carriage also serves as a counter-bending roller.

Weiterhin ist der Bundöffner um eine Schwenkachse zwischen einer Betriebsund einer Ruhestellung hin und her schwenkbar.Furthermore, the collar opener can be pivoted back and forth about a pivot axis between an operating position and a rest position.
Das Dokument DE 198 03 091 A1 offenbart ein Betriebsverfahren für eine Band-umsetzanlage mit einer Aufwickelstation mit je einer einlauf- und auslauf- seitigen Aufwickelrolle und einer Abwickelstation mit je einer einlauf- und aus- laufseitigen Abwickelrolle, wobei ein Band in der Aufwickelstation zu einem Bund aufgewickelt wird, oder ein Bund auf die Aufwickelrollen aufgesetzt wird und wobei der Bund beim Aufwickeln bzw. nach dem Aufsetzen von den Auf- wickelrollen getragen wird,Document DE 198 03 091 A1 discloses an operating method for a belt transfer system with a winding station with a winding roller on the inlet and outlet sides and a winding station with a winding roller on the inlet and outlet sides, one belt in the winding station Bundle is wound up, or a bundle is placed on the wind-up rolls and the bundle is carried by the wind-up rolls during winding up or after being put on,
Zum Abwickeln wird der Bund zu der Abwickelstation transferiert und nach dem Transferieren wird der Bund beim Abwickeln von den Abwickelrollen getragen. Zum Transferieren des Bundes werden die Wickelstationen aufeinander zu bewegt, die einlaufseitige Aufwickelrolle wird angehoben. Die entsprechend dem Betriebsverfahren vorgesehene Bundumsetzanlage mit einer Aufwickelstation und mit je einer einlauf- und auslaufseitigen Aufwickelrolle sowie einer Abwickelstation mit einer einlauf- und auslaufseitigen Abwik- kelrolle, ist so ausgebildet, dass die Wickelstationen aufeinander zubewegbar sind und dass die einlaufseitige Aufwickelrolle anhebbar ist.For unwinding, the bundle is transferred to the unwinding station and after the transfer, the bundle is carried by the unwinding rollers during unwinding. To transfer the bundle, the winding stations are moved towards each other, the take-up reel is raised. The coil transfer system provided in accordance with the operating method with a winding station and with a winding roller on the inlet and outlet sides and an unwinding station with a winding roller on the inlet and outlet sides is designed such that the winding stations can be moved towards one another and that the winding roller on the inlet side can be raised.
Das Dokument DE-30 31 825 C2 beschreibt eine Vorrichtung zum Übergeben von zu Bunden gewickelten vorgewalzten heißen Metallbändern von einer, einer Vorwalzstraße zugeordneten Aufwickelstation an eine einer Fertigwalzstra- ße zugeordnete Abwickelstation. Die Übergabevorrichtung besteht aus einem quer zur Bewegungsrichtung des Bandes auf einem Gleis bewegbaren Fahrzeug, welches einen in Arbeitsstellung etwa vertikalen Arm mit einer seitlich vorstehenden Auflagefläche für den Bund aufweist. Der Arm ist Bestandteil eines auf einen Grund-rahmen angeordneten Oberteils. Um das Aufnehmen und Absetzen des Bundes zu ermöglichen, ist die Strecke verstellbar. Das Gleis für das Fahrzeug ist in der Walzanlage unter Flur verlegt. Der Oberteil des Fahrzeugs besteht aus Gelenkhebeln und ist in zusammengelegtem Zustand unter der Abwickelstation der Fertigwalzstraße hindurch bewegbar.Document DE-30 31 825 C2 describes a device for transferring pre-rolled hot metal strips wound into bundles from a winding station assigned to a roughing train to an unwinding station assigned to a finishing train. The transfer device consists of a vehicle which is movable transversely to the direction of movement of the belt on a track and which has an approximately vertical arm in the working position with a laterally projecting support surface for the collar. The arm is part of an upper part arranged on a base frame. The route is adjustable to enable the federal government to be picked up and set down. The track for the vehicle is installed in the rolling mill under the floor. The upper part of the vehicle consists of articulated levers and, when folded, can be moved under the unwinding station of the finishing mill.
Ausgehend vom vorgenannten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine neue konstruktive Lösung für die Ausgestaltung der Muldenrolle einer Haspelvorrichtung anzugeben, damit sich diese besser einem balligen Coil anpassen kann und für eine gute Abstützung über die Coilbreite sorgt, damit Markierungsmarken, besonders bei dünnen Bändern sicher ver- mieden werden.Starting from the aforementioned prior art, the invention has for its object to provide a new constructive solution for the design of the trough roller of a reel device, so that it can better adapt to a spherical coil and provides good support over the coil width, so that marking marks, especially at thin tapes can be safely avoided.
Zur Lösung der Aufgabe wird bei einer Haspelvorrichtung mit wenigstens einer antreibbaren Muldenrolle gemäß Oberbegriff von Anspruch 1 erfindungsgemäß von der Maßnahme Gebrauch gemacht, dass die Muldenrolle mit einem ela- stisch verfahrbaren Mantelring ausgebildet ist. Zur weiteren Ausbildung der Muldenrolle wird vorgeschlagen, dass die Arbeitsfläche der Muldenrolle mit einer Reihe aneinander anschließender Mantelringe ausgebildet ist, die einen Kern der Muldenrolle mit Durchmesser-Differenz umgebend, mittels gegen die Mantelringe von innen her federbelasteter Stützkörper derart gleichmäßig abgestützt sind, dass sie die Kontaktfläche der Mulden- rolle mit dem Coil über deren gesamte Längserstreckung mit gleichmäßigen Anlagedruck beaufschlagt.To achieve the object, in a reel device with at least one drivable trough roller according to the preamble of claim 1, use is made according to the invention of the measure that the trough roller is designed with an elastically movable jacket ring. To further develop the trough roller, it is proposed that the working surface of the trough roller be formed with a row of adjoining jacket rings which surround a core of the trough roller with a difference in diameter by means of support bodies which are spring-loaded from the inside against the jacket rings in such a way that they support the The contact surface of the trough roller with the coil is subjected to uniform contact pressure over its entire longitudinal extent.
Eine weitere Ausgestaltung der erfindungsgemäßen Haspelvorrichtung mit Muldenrolle sieht vor, dass die Stützkörper in Anpassung an den inneren Kreis der Mantelringe an ihren Kontaktflächen bombiert ausgebildet sind.A further embodiment of the reel device according to the invention with a trough roller provides that the support bodies are designed to be curved on their contact surfaces in adaptation to the inner circle of the casing rings.
Weiter sieht die Erfindung vor, dass jeder Stützkörper mit einem Paket aus Tellerfedern mit vorgebbarer Vorspannkraft hinterfüttert ist. Dabei kann vorgesehen sein, dass die Stützkörper mit vorspannbarer Federkraft in die Mantel- ringe eingespannt sind.The invention further provides that each support body is back-lined with a package of disc springs with a predeterminable prestressing force. It can be provided that the support bodies are clamped into the casing rings with prestressable spring force.
Um stoßfreie Übergänge der Mantelringe zu schaffen, ist mit der Erfindung weiter vorgesehen, dass aneinander anschließende Mantelringe mit einer schrägen Anfrasung an die benachbarten Mantelringe anschließen, insbeson- dere bei Mantelringen mit Durchmesser-Differenz.In order to create bumpless transitions of the outer rings, the invention further provides that adjacent outer rings connect with an oblique chamfer to the adjacent outer rings, particularly in the case of outer rings with a difference in diameter.
Nach einer weiteren Ausgestaltung der Muldenrolle können die Laufflächen der Mantelringe mit einer geringen Bombierung ausgebildet sein, die das Maß der Durchmesserdifferenz jedoch nicht überschreitet.According to a further embodiment of the trough roller, the running surfaces of the casing rings can be designed with a slight crowning, which, however, does not exceed the dimension of the difference in diameter.
Die Haspelvorrichtung wird dadurch weiterentwickelt, dass jeweils zwei in vorgebbarem achsparallelem Abstand anordenbare Muldenrollen unter Ausbildung einer zwischen diesen muldenförmigen Vertiefung zur Aufnahme der zylinder- förmigen Last des Coils miteinander zusammen wirken. Wenigstens eine dieser Muldenrollen ist mit einem Rotationsantrieb ausgestattet. Die Muldenrolle um- fasst vorteilhafterweise eine massive zentrale Welle, auf der Welle einen mittle- ren Ring zur Aufnahme federbelastbarer Stützkörper und einen Mantelring mit einem äußeren Laufring für die Lastaufnahme in Form eines Coils.The reel device is further developed in that two trough rollers, which can be arranged at a predeterminable, axially parallel distance, cooperate with one another to form a trough-shaped recess between them for receiving the cylindrical load of the coil. At least one of these trough rollers is equipped with a rotary drive. The trough roller advantageously comprises a solid central shaft, on which a medium Ren ring for receiving spring-loaded support body and a jacket ring with an outer race for load absorption in the form of a coil.
Und schließlich weist die Muldenrolle der Haspelvorrichtung eine sich beim Abrollen auf einem Coil ausbildende, insbesondere konkave Kontaktfläche auf die mittels der elastisch federnd nachgiebigen Mantelringe dem üblicherweise balligen Umfang des Coils selbsttätig anpassbar ist.And finally, the trough roller of the reel device has a contact surface, in particular a concave one, which forms when it is rolled on a coil and which can be automatically adapted to the usually spherical circumference of the coil by means of the elastically resilient jacket rings.
Weitere Einzelheiten, Merkmale und Vorteile der Erfindung ergeben sich aus der nachstehenden Erläuterung eines in der Zeichnung schematisch darge- stellten Ausführungsbeispieles. Es zeigen:Further details, features and advantages of the invention result from the following explanation of an exemplary embodiment shown schematically in the drawing. Show it:
Figur 1 den Schnitt durch die Muldenrolle in einer Ebene senkrecht zurFigure 1 shows the section through the trough roller in a plane perpendicular to
Rotationsachse;Axis of rotation;
Figur 1a in Vorderansicht zwei im Abstand angeordnete Muldenrollen mit der Lastaufnahme zweier ungleich großer Coils;Figure 1a in front view two spaced-apart trough rollers with the load bearing of two coils of different sizes;
Figur 1b die Muldenrolle in Seitenansicht mit angedeuteter Lasteinwirkung;Figure 1b the trough roller in side view with indicated load action;
Figur 2 die Muldenrolle in einer Teil-Ansicht, und darunter die dargestellten Muldenrolle im Teil-Schnitt einer Schnittebene parallel zur Mittellinie.Figure 2 shows the trough roller in a partial view, and below the trough roller shown in partial section of a cutting plane parallel to the center line.
Die Zusammenschau der Zeichnungen von Figur 1 , 1a und 1b, sowie von Figur 2 zeigt, dass die Arbeitsfläche 3 der Muldenrolle 1 mit einer Reihe aneinander anschließender Mantelringe 4 ausgebildet ist, die einen Kern 5 der Muldenrolle 1 mit Durchmesser-Differenz umgeben. Mittels aus diesem Kern 5 gegen die Mantelringe 4 von innen her vorstehende, federbelastete Stützkörper 6 ist die Arbeitsfläche 3 gleichmäßig abgestützt. Hierbei ist die Kontaktlinie 7 der Mul- denrolle 1 über deren gesamte Längserstreckung L mit gleichmäßigem Anlagedruck beaufschlagt. Die Stützkörper 6 sind in Anpassung an den Innenkreis der Mantelringe 4 an ihren Kontaktflächen mit den Mantelringen bombiert ausgebildet. Jeder dieser Stützkörper ist mit einem Paket aus Tellerfedern 8 mit vorgebbarer Vorspannkraft hinterfüttert. Um dies zu erreichen, sind die Stützkörper 6 mit vorspannba- rer Federkraft in die Mantelringe 4 eingespannt.The overview of the drawings of Figures 1, 1a and 1b, as well as of Figure 2 shows that the working surface 3 of the trough roller 1 is formed with a series of adjoining casing rings 4 which surround a core 5 of the trough roller 1 with a difference in diameter. The working surface 3 is evenly supported by means of this core 5, against the casing rings 4, spring-loaded support body 6 projecting from the inside. In this case, the contact line 7 of the trough roller 1 is subjected to a uniform contact pressure over its entire longitudinal extent L. The support bodies 6 are designed to match the inner circle of the casing rings 4 at their contact surfaces with the casing rings. Each of these support bodies is backed with a package of disc springs 8 with a predeterminable prestressing force. In order to achieve this, the supporting bodies 6 are clamped into the jacket rings 4 with a prestressable spring force.
Weiterhin ist vorgesehen, dass die Mantelringe 4 zur Kompensation einer errechenbaren bzw. nach der Erfahrung kalkulierbaren, lastbedingten Durchbiegung der Muldenrolle 1 gegen deren Mitte im Außendurchmesser zunehmend.Furthermore, it is provided that the jacket rings 4 to compensate for a calculable or, based on experience, load-dependent deflection of the trough roller 1 against its center in the outer diameter.
Figur 1 zeigt einerseits ein im Durchmesser großes Coil 2 und andererseits ein im Durchmesser kleineres Coil 2 aufgelagert auf zwei Muldenrollen 1 , 1 ', die im vorgegebenen Abstand ihrer Achsen feststehend gelagert sind.FIG. 1 shows on the one hand a coil 2 with a large diameter and, on the other hand, a coil 2 with a smaller diameter supported on two trough rollers 1, 1 ', which are fixedly mounted at the predetermined spacing of their axes.
Man erkennt bei dieser Darstellung der Figur 1a, dass die Krümmung der Oberflächen der Coils 2, 2' nach Maßgabe von deren Durchmessergröße erheblich variiert. Das bereits teilweise abgewickelte Coil 2' beansprucht zwischen den Muldenrollen 1 , 1 ' eine tiefere Einbuchtung seiner Oberfläche zwischen den beiden Rollen, während das Coil 2 mit dem wesentlich größeren Durchmesser eine flachere Kurvenform seiner Oberfläche zwischen den beiden Rollen 1 , 1 ' beansprucht. Auch sind die Kontaktpunkte bzw. die Kontaktlinien zueinander verschoben.It can be seen in this illustration of FIG. 1a that the curvature of the surfaces of the coils 2, 2 'varies considerably in accordance with their diameter size. The already partially unwound coil 2 'between the trough rollers 1, 1' claims a deeper indentation of its surface between the two rollers, while the coil 2 with the much larger diameter claims a flatter curve shape of its surface between the two rollers 1, 1 '. The contact points or the contact lines are also shifted relative to one another.
Figur 1b zeigt eine Seitenansicht einer Muldenrolle 1 mit gleichmäßiger Lastverteilung über dessen Länge in Längsrichtung mit einzelnen, auf die nebeneinander liegenden Mantelringe 4 einwirkenden Lastkräfte. Diese bewirken erfahrungsgemäß eine begrenzte Durchbiegung der Muldenrolle 1 , die sich gewichtsbedingt beim vollen Coil stärker auswirkt, als beim nahezu abgehaspelten Coil. Mittels der dargestellten Muldenrollen können diese Unterschiede ausge- glichen werden. Bei dem gezeigten Ausführungsbeispiel der Figur 1 a ist die rechtsseitige Muldenrolle 1' mit einem motorischen Antrieb ausgebildet und entsprechend dargestellt.FIG. 1b shows a side view of a trough roller 1 with an even load distribution over its length in the longitudinal direction with individual load forces acting on the side rings 4 lying next to one another. Experience has shown that these cause a limited deflection of the trough roller 1, which, due to the weight, has a greater effect on the full coil than on the coil that has almost been unwound. These differences can be compensated for using the trough rollers shown. In the exemplary embodiment shown in FIG. 1 a, the right-hand trough roller 1 ′ is designed with a motor drive and is shown accordingly.
Figur 2 zeigt, dass mit geringer Durchmesser-Differenz aneinander anschlie- ßende Mantelringe 4 mit jeweils einer schrägen Anphasung an den jeweils benachbarten Mantelring 4 anschließen. Auch sind deren Laufflächen mit einer geringfügigen Bombierung 9 ausgebildet, welche das Maß der Durchmesser- Differenz jedoch nicht überschreitet.FIG. 2 shows that with a small difference in diameter, adjoining jacket rings 4, each with an oblique chamfer, connect to the adjacent jacket ring 4. The treads are also designed with a slight crown 9, which, however, does not exceed the difference in diameter.
Figur 2 zeigt im unteren Schnittbild deutlich den inneren Aufbau der Muldenrolle 1 nach der Erfindung. Dabei umfassen die Mantelringe 4 der Muldenrolle 1 eine massive zentrale Welle 5. Diese trägt einen mittleren Ring 11 zur Aufnahme federbelastbarer Stützkörper 6 und einen äußeren Laufring 12 für die Lastaufnahme.Figure 2 shows in the lower sectional view clearly the inner structure of the trough roller 1 according to the invention. The casing rings 4 of the trough roller 1 comprise a solid central shaft 5. This carries a central ring 11 for receiving spring-loaded support bodies 6 and an outer race 12 for the load bearing.
Mit dieser erfindungsgemäßen Bauart der Muldenrolle 1 wird in überraschend zweckmäßiger und unkomplizierter Art erreicht, dass sich die Muldenrolle auch einem balligen Coil anpasst und für eine gute Abstützung über die Coilbreite sorgt und vermeidet, dass besonders bei dünnen Bändern unerwünschte Mar- kierungen auftreten können. With this type of trough roller 1 according to the invention, it is achieved in a surprisingly expedient and uncomplicated manner that the trough roller also adapts to a spherical coil and provides good support over the coil width and avoids that undesired markings can occur, particularly in the case of thin strips.
