Description

Die Erfindung betrifft eine Vorrichtung zum Anwickeln von bandförmigem Walzgut auf den Dorn eines Haspels, bei der die ersten Windungen mittels einer die Windungen teilweise umschlingenden, endlos über Umlenkräder geführen Zahnkette gehalten werden, wobei die Umlenkräder mit einer der Zahnkette entsprechenden Umfangsverzahnung versehen sind und mindestens ein Teil der Umlenkräder angetrieben ist.The invention relates to a device for winding strip-shaped rolling stock on the mandrel of a reel, in which the first turns by means of one of the turns looping tooth chain, endlessly guided over deflection wheels are held, the deflection wheels with one of the toothed chain corresponding peripheral teeth are provided and at least part of the deflection wheels is driven.

Insbesondere hervorgerufen durch die Entwicklung neuer Bandgießverfahren gewinnt das Aufwickeln von Warmbändern, beispielsweise zum Zwischenspeichern, immer mehr Bedeutung. Bei kontinuierlichen Verfahren wird bevorzugt ein Karussellhaspel verwendet, weil diese Haspeleinrichtungen mit großer Betriebssicherheit betrieben werden können; denn das Hinführen der Bandanfangsstücke zum Wickeldorn ist weitgehend störungsfrei erreichbar. Beim Anwickeln des bandförmigen Walzgutes auf die Haspeldorne ist besonderes Augenmerk auf das Anwickeln der ersten zwei bis drei Windungen zu legen, die rutschfest am Dorn anliegen sollen.In particular caused by the development of new ones Strip casting process wins the winding of hot strips, for example, for temporary storage, more and more meaning. In the case of continuous processes, a carousel reel is preferred used because these reelers with great Operational safety can be operated; because leading the beginning of the strip to the winding mandrel is largely trouble-free reachable. When winding the strip-shaped rolling stock onto the Reel mandrels pay special attention to the winding of the the first two to three turns, which are non-slip on the Thorn should rest.

Bei Warmbandhaspeln, die gewöhnlich als Unterflurhaspeln betrieben werden ist bekannt, für das Umschlingen der ersten Windungen angetriebene bewegliche Andrückrollen zu verwenden, die nach dem Anwickeln von zwei bis drei Windungen weggeschwenkt werden. Derartige Andrückrollen können aus Platzgründen bei Karussellhaspeln nicht zum Einsatz kommen, weil der schwenkbare Kopf des Karussellhaspels mindestens zwei Dorne trägt, die durch Schwenkung in Arbeitsposition gebracht werden. For hot strip reels, which are usually operated as underfloor reels is known for looping the first turns to use driven movable pressure rollers, which after can be pivoted away from winding two to three turns. Such pressure rollers can be used for carousel reels for reasons of space are not used because the swiveling head of the Carousel reel carries at least two mandrels that pass through Swiveling be brought into working position.

Zum Anwickeln von Kaltband sind Riemenwickler bekannt, bei denen ein endlos um Umlenkrollen umlaufender Riemen den Haspeldorn und damit die auf ihm aufliegenden Windungen teilweise umschlingt. Der Riemen hat keinen Antrieb und wird durch Reibkontakt vom Dorn mitgenommen. Riemen und Umlenkrollen sind an wegschwenkbaren Rahmenteilen angeordnet, die zum Anwickeln eingeschwenkt und nach dem Abwickelvorgang weggeschwenkt werden können. Bei Kaltbandwicklern werden vorzugsweise Metalcord-Gurte verwendet, das sind Gummi- bzw. Kautschuk-Gurte mit besonders abriebfester Oberfläche, die im Inneren mit hochelastischen Stahlseilen armiert sind. Derartige Gurte sind einsatzfähig bis zu Temperaturen von 200 Grad C und für geringe Wickelgeschwindigkeiten von ca. 1,5 m/sec.Belt winders are known for winding cold strip which an endless belt around the pulleys Haspeldorn and thus the turns on it partially wraps around. The belt has no drive and is through Frictional contact carried by the mandrel. Belts and pulleys are arranged on swing-away frame parts, which can be rolled up swung in and swung away after unwinding can. In cold strip winders, metal cord belts are preferred used, these are rubber or rubber belts with particularly abrasion-resistant surface, the inside with highly elastic steel cables are reinforced. Such straps are operational up to temperatures of 200 degrees C and for low Winding speeds of approx. 1.5 m / sec.

Aus der gattungsbildenden DE-AS 12 48 602 ist ein Riemenschlinger für einen Kaltbandhaspel bekannt, der in der Art einer Raupenkette an mindestens einer Zahnkette drehbar gelagerte Druckkörper aufweist, die sich quer zu der Zahnkette erstrecken. Die Druckkörper sind mit einem elastischen Material überzogen. Der bekannte Riemenschlinger ist für Warmband ungeeignet, weil die Druckstücke nicht temperaturbelastbar sind und eine Abfuhr von Zunder nicht ermöglichen. Die bekannte Einrichtung ist deshalb nur für Kaltband geeignet.From the generic DE-AS 12 48 602 is a sling known for a cold strip reel, which is in the manner of a caterpillar track pressure body rotatably mounted on at least one toothed chain has, which extend transversely to the tooth chain. The Pressure hulls are covered with an elastic material. The well-known belt sling is unsuitable for hot strip because the pressure pieces are not temperature resistant and a discharge from tinder. The well-known facility is therefore only suitable for cold strip.

Zum Aufwickeln von Warmbändern ist es bekannt, Drahtgliederbänder aus Rund- oder Flachdraht zu verwenden, die aus Chrom-Nickel-Stählen gefertigt sind. Diese Gliederbänder verschleißen wegen der hohen mechanischen Belastung an den Umlenkungen, insbesondere bei hohen Geschwindigkeiten sehr schnell, wobei Wickelgeschwindigkeiten von ca. 0,5 m/sec. die obere Grenze darstellen. Die Temperaturbelastung derartiger Drahtgliederbänder sollte 400 Grad C nicht überschreiten. For the winding of hot strips, it is known to use wire link strips made of round or flat wire, made of chrome-nickel steel are made. These link bands wear out because of the high mechanical load on the deflections, in particular at high speeds very quickly, whereby Winding speeds of approx. 0.5 m / sec. the upper limit represent. The temperature load of such wire link belts should not exceed 400 degrees C.

Alle vorstehend beschriebenen Anwickelvorrichtungen sind nur für relativ geringe Wickelgeschwindigkeiten und begrenzte Temperaturbereiche geeignet und haben sich, insbesondere für den rauhen Betrieb in Warmbandwalzwerken,nicht durchsetzen können. Die Standzeit der bekannten Andrückvorrichtungen ist äußerst gering und wird mit 1 bis 2 Wochen angegeben.All of the winding devices described above are only for relatively low winding speeds and limited Suitable temperature ranges and have, especially for do not enforce the rough operation in hot strip rolling mills can. The service life of the known pressing devices is extremely low and is given as 1 to 2 weeks.

Ein weiterer Nachteil der in Warmhaspelanlagen eingesetzten Drahtgliederbänder ist ihre Verschmutzung durch den anfallenden Zunder. Diese erfordert eine aufwendige Wartung der Gliederbänder, wenn die oben angegebene Standzeit erreicht werden soll. Auch sind die Drahtgliederbänder empfindlich, wenn Bänder mit unterschiedlichen Breiten gewalzt werden müssen; denn sie sind nicht geeignet, Querkräfte aufzunehmen. Vorzugsweise sollte beim Einsatz dieser Drahtgliederbänder die Bandbreite größer als die Gurtbreite sein, was aber einen häufigen Wechsel der Gurte beim Walzen von Bändern mit unterschiedlicher Breite erforderlich macht. Auch ist die ruckartige Beschleunigung beim Kontakt mit dem Dorn für die Lebensdauer der Drahtgliederbänder nachteilig.Another disadvantage of those used in hot reel plants Wire link belts are their pollution by the accumulating Tinder. This requires extensive maintenance of the link belts, if the service life specified above is to be achieved. Also the wire link belts are sensitive when using belts different widths must be rolled; because they are not suitable for absorbing lateral forces. Preferably should when using these wire link belts, the bandwidth is larger than the belt width, which is a frequent change of belts required when rolling strips of different widths makes. Also the jerky acceleration on contact with the mandrel for the life of the wire link belts disadvantageous.

Ausgehend von den beschriebenen Nachteilen und Problemen des Standes der Technik ist es Aufgabe der vorliegenden Erfindung, eine gattungsgemäße Anwickelvorrichtung so zu verbessern, daß sie mit hohen Standzeiten für das Aufwickeln von Warmband auf Karussellhaspeln geeignet ist, wobei bei schonender Behandlung der Bandoberfläche hohe Wickelgeschwindigkeiten erreichbar sein sollen.Based on the disadvantages and problems of the State of the art it is an object of the present invention to improve a generic winding device so that with long service life for winding hot strip Carousel reel is suitable, with gentle treatment high winding speeds attainable on the belt surface should be.

Zur Lösung der Aufgabe wird erfindungsgemäß vorgeschlagen, daß die Zahnkette aus einem aufgelockerten Laschenverband mit mehreren nebeneinander angeordneten und durch Distanzscheiben auf Abstand gehaltenen Kettenteilen besteht, die einen gemeinsamen Strang bilden, wobei die Kettenglieder auf der dem anzuwickelnden Band zugewandten Seite glatt und auf der den Umlenkrädern zugewandten Seite verzahnt ausgebildet sind.To solve the problem, the invention proposes that the tooth chain with a loosened tab link with several arranged side by side and by spacers spaced chain parts that one form a common strand, with the chain links on the the side facing to be wound smooth and on the the side facing the deflection wheels are toothed.

Eine derartige Zahnkette, beispielsweise aus wärmebehandeltem Kettenstahl, ist in hohem Maße wärmeresistent und verschleißfest. Die glatte Seite der Zahnkette schont die Bandoberfläche, wobei durch den Antrieb der Umlenkräder eine mit dem einlaufenden Band bzw. dem Dorn synchrone Geschwindigkeit einstellbar ist. Dadurch werden Relativbewegungen zwischen der Zahnkette und der Bandoberfläche, die zu Verschleiß führen könnten, sicher vermieden. Der Rücken der Zahnkette, d.h. die dem anzuwickelnden Band zugewandte Seite ist fast biegesteif, kann aber über den großen Dorndurchmesser des Haspeldorns gut gebogen werden. In Gegenrichtung ist die Zahnkette gut kurvengängig, so daß sie über die verzahnten Umlenkräder geführt werden kann. Die vorgeschlagene Zahnkette ist für Geschwindigkeiten bis 6 m/sec. ausgelegt und kann dabei problemlos umgelenkt werden. Der Kontakt mit bis zu 600 Grad C heißen Warmbändern erfolgt kurzzeitig mit längeren Abkühlphasen, so daß eine niedrige Beharrungstemperatur zu erwarten ist. Durch eine zyklische Ölsprühschmierung können die Gelenke der Zahnkette geschmiert und gleichzeitig die Kettenglieder gekühlt werden.Such a tooth chain, for example made of heat-treated Chain steel, is highly heat-resistant and wear-resistant. The smooth side of the tooth chain protects the belt surface, whereby by driving the idler wheels one with the incoming one Band or the mandrel synchronous speed is adjustable. As a result, relative movements between the tooth chain and the belt surface, which could lead to wear avoided. The back of the tooth chain, i.e. the one to be wrapped up The side facing the belt is almost rigid, but can be moved over the large mandrel diameter of the coiler mandrel can be bent well. In the opposite direction, the tooth chain is easy to turn, so that it can be guided over the toothed deflection wheels. The proposed tooth chain is for speeds up to 6 m / sec. designed and can be easily redirected. The contact with hot tapes up to 600 degrees C for a short time with longer cooling phases, so that a low steady-state temperature is to be expected. With cyclical oil spray lubrication the joints of the tooth chain are lubricated and at the same time the Chain links are cooled.

Durch die regelmäßigen Lücken im Laschenverband erfolgt eine gute Zunderabfuhr, so daß Verschmutzungen der Oberfläche der Zahnkette nicht auftreten. Ein solcher Laschenverband aus mehreren nebeneinander angeordneten Kettenteilen ist für verschiedene Bandbreiten einsetzbar, so daß ein Austausch beim Wickeln unterschiedlicher Bandbreiten nicht erforderlich ist.Due to the regular gaps in the tab linkage, there is one good scale removal, so that dirt on the surface of the Tooth chain does not occur. Such a tab brace several chain parts arranged side by side is for Different bandwidths can be used, so that an exchange when Wrapping different bandwidths is not necessary.

Um die Seitenführung jeder Zahnkette sicherzustellen, wird nach einem weiteren Merkmal der Erfindung vorgeschlagen, daß einzelne Laschen der Zahnkette in Umfangsnuten der umfangsverzahnten Umlenkräder eingreifen. To ensure the lateral guidance of each tooth chain, proposed according to a further feature of the invention that individual plates of the tooth chain in circumferential grooves of the engage circumferentially toothed deflection wheels.

Die erfindungsgemäße Zahnkette erhöht die Lebensdauer der Anwickelvorrichtung wesentlich, und zwar auf ca. 2 Jahre.The tooth chain according to the invention increases the life of the Winding device essential, and that for about 2 years.
