Description

VORRICHTUNG UND VERFAHREN ZUM AUFHASPELN EINES DEVICE AND METHOD FOR HITCHING ONE
BANDES MIT VERÄNDERLICHERBANDES WITH CHANGING
BANDDICKE, INSBESONDERE EINES METALLBANDESBAND THICKNESS, IN PARTICULAR OF A METAL BAND
Die Erfindung bezieht sich auf eine Vorrichtung zum Aufhaspeln eines Bandes mit veränderlicher Banddicke, insbesondere eines ebenen oder eines mit Konturen versehenen, eines flexibel gewalzten und/oder eines profilgewalzten Metallbandes, insbesondere aus Stahl, zu einem Wickel mit einer Anordnung zum Einbringen eines verformbaren Materials auf das aufzuhaspelnde Band.The invention relates to a device for winding a tape with variable strip thickness, in particular a flat or contoured, a flexibly rolled and / or a profile-rolled metal strip, in particular made of steel, to a winding with an arrangement for introducing a deformable material the rewinding tape.
Vor allem betrifft die Erfindung das Aufwickeln von Spaltbändern. Spaltbänder entstehen, wenn bandförmiges Material, insbesondere metallisches Breitband, von einem Coil abgezogen und in Längsrichtung in schmale Bänder längsgeteilt, d. h. gespalten, wird. Die so erzeugten schmalen Spaltbänder werden anschließend auf einen gemeinsamen Dorn oder separate Dorne aufgewickelt. Bevorzugt werden Verbundwickel aus einer Vielzahl nebeneinanderliegender Spaltbänder erzeugt. Zum Ausgleich von Dickenabweichungen über der Breite des Bandes, die beim Aufwickeln der Spaltbänder, insbesondere in den Randbereichen des Bandes, zu einer kegeligen oder bombierten Oberfläche führen, müssen Einlagen in die Wickel der Spaltbänder eingebracht werden.Above all, the invention relates to the winding of slit strips. Slit strips arise when strip-shaped material, in particular metallic broadband, drawn from a coil and longitudinally divided into narrow bands, d. H. split, will. The narrow slit strips produced in this way are then wound onto a common mandrel or separate mandrels. Preferably, composite rolls are produced from a multiplicity of adjacent split strips. To compensate for variations in thickness over the width of the strip, which lead to a conical or cambered surface when winding the slit strips, in particular in the edge regions of the strip deposits must be introduced into the winding of the slit strips.
Auch beim Aufwickeln von gespaltenem Bandmaterial auf eine durchgehende Trommel mit mehreren, durch Blechronden voneinander getrennten, koaxial nebeneinanderliegenden Aufwickelhaspeln von Längsteilanlagen kommt es infolge unterschiedlicher Banddicken und Beschichtungsstärken zu mehr oder weniger festgewickelten Coils mit entsprechend unterschiedlichem Banddurchhang. Die ungleichmäßige Wicklung der Coils wirkt sich nachteilig auf deren Aussehen, Verpackung, das Ablaufverhalten und die Reibung zwischen den einzelnen Bandwindungen aus. Um diese Mängel zu vermeiden, ist es bekannt, zwischen die Windungen der Spaltbänder Papier- oder Pappstreifen geeigneter Längenabmessungen einzuwickeln. Dies geschieht häufig dadurch, dass der Papierstreifen von Hand in den Wickelschlitz zwischen dem auflaufenden Band und dem Coil eingelegt wird.Even when winding split strip material on a continuous drum with several, separated by circular blanks, coaxially juxtaposed Aufwickelhaspeln of slitting lines it comes as a result of different thicknesses and thicknesses more or less tightly wound coils with a correspondingly different tape sag. The uneven winding of the coils has a detrimental effect on their appearance, packaging, the drainage behavior and the friction between the individual tape turns. To avoid these shortcomings, it is known to wrap paper or cardboard strips of suitable length dimensions between the turns of the slit strips. This often happens because the Paper strip is inserted by hand into the winding slot between the incoming tape and the coil.
Aus der DE 80 06 563 IM ist eine Vorrichtung zum Einführen von Zwischenla- gestreifen in den Wickelschlitz von zu Coils aufzuwickelndem Bandmaterial bekannt, bei der der Papierstreifen mittels eines Treibrollenpaars in Richtung zu dem Wickelschlitz gefördert wird. Hierbei ist der Vorratsbehälter für den Papierstreifen als den Zwischenlagepapierstreifen enthaltender Trommelbehälter ausgebildet, hinter dessen Streifenauslaufschlitz das durch einen Elektromotor angetriebene Treibrollenpaar vorgesehen ist. Hinter dem Treibrollenpaar ist eine Streifentrenn- und Perforiervorrichtung vorgesehen. Dadurch kann der Zwischen legestreifen durch das Treibrollenpaar mit großer Geschwindigkeit und unter gleichzeitiger vorübergehender Verformung zu einem nach unten offenen, stabilen Lufttrageprofil freifliegend in den Wickelschlitz eingeschossen werden. Der Zwischenlagestreifen muss durch die dachförmige Profilierung der Treibrollen derart verformt werden, dass er ein hinreichend stabiles, von der Luft getragenes Profil enthält, das es erlaubt, ihn auch über eine größere Freiflugstrecke in den Wickelschlitz einzuschießen, wobei außer der Lufttragewirkung zugleich auch die Beschleunigungswirkung ausgenutzt wird.From DE 80 06 563 IM a device for introducing Zwischenla- strips in the winding slot of coils to be wound coils is known, in which the paper strip is conveyed by means of a pair of driving rollers in the direction of the winding slot. Here, the storage container for the paper strip as the intermediate layer paper strip containing drum container is formed behind the strip outlet slot which is provided by an electric motor driven roller pair. Behind the pair of driving wheels, a strip separating and perforating device is provided. As a result, the intermediate legestreifen by the pair of driving wheels at high speed and with simultaneous temporary deformation to a downwardly open, stable air support profile free-flying are injected into the winding slot. The liner strip must be deformed by the roof-shaped profiling of the drive rollers so that it contains a sufficiently stable, carried by the air profile, which allows him to shoot over a larger free flight distance in the winding slot, which exploited in addition to the air bearing effect at the same time the acceleration effect becomes.
Die Zwischenlagestreifen werden entweder einem die Streifen in angemessenen Längen enthaltenden Stapelbehälter entnommen und einzeln in den Wickel des Metallbandes eingeschossen oder von einem Streifen-Vorratswickel abgezogen und in jeweils notwendiger Einwickellänge abgetrennt.The interleaving strips are either taken from a stack container containing the strips in appropriate lengths and individually inserted into the coil of the metal strip or withdrawn from a strip supply roll and separated in each necessary wrapping length.
In der EP 0 166 795 B1 wird ein Verfahren zum Aufwickeln von mehreren durch Längsteilen von bandförmigen Material erzeugten Spaltbändern auf einen gemeinsamen Wickeldorn beschrieben, bei dem das bandförmige Material eine Dickenabweichung über seine Breite aufweist.EP 0 166 795 B1 describes a method for winding a plurality of split strips produced by slitting strip-shaped material onto a common winding mandrel in which the strip-shaped material has a thickness deviation across its width.
Das Verfahren ist dadurch gekennzeichnet, dass die Spaltbänder gleichzeitig zu einem Verbundwickel mit einer sich über die Breite aller nebeneinander verlau- fender Spaltbänder erstreckenden verformbaren bandförmigen Einlage aufgewickelt werden. Dabei wird die Dicke der Einlage größer als die Dickenabweichung über die Breite des bandförmigen Materials gewählt. Beim Aufwickeln der Spaltbänder werden durch Ausüben einer Kraft auf die jeweils oberste Wickellage der Spaltbänder und/oder die Einlage in radialer Richtung des Verbundwickels die dickeren Spaltbänder stärker als die dünneren in die Einlage eingedrückt und die Spaltbänder durch entsprechende Verformung der Einlage zu einem Verbundwickel mit zylindrischer Hüllfläche aufgewickelt. Gemäß diesem Verfahren kann als bandförmiges Material ein nicht-beschichtetes oder ein beschichtetes metallisches Band aufgewickelt werden. Als verformbare Einlage werden vorzugsweise Papier, Pappe, Kunststoff, insbesondere Schaumstoff, oder ein mit einem Korrosionsschutzmittel imprägniertes Papier verwendet.The method is characterized in that the slit strips at the same time to a composite wrap having a width of all side by side Fender slit strip extending deformable band-shaped insert to be wound up. The thickness of the insert is chosen to be greater than the thickness deviation across the width of the band-shaped material. When winding the slit strips are pressed by exerting a force on the respective uppermost winding layer of the slit strips and / or the insert in the radial direction of the composite coil thicker slit strips stronger than the thinner in the insert and the slit strips by appropriate deformation of the insert to a composite coil with cylindrical Covering surface wound up. According to this method, a non-coated or a coated metallic strip can be wound up as a band-shaped material. As a deformable insert preferably paper, cardboard, plastic, in particular foam, or used with a corrosion inhibitor impregnated paper.
Femer ist es bekannt, nicht nur ebene Metallbänder herzustellen, sondern auch solche, die Konturen in Längs- und/oder in Querrichtung aufweisen. In der DE 198 31 882 A1 werden ein Verfahren und eine Walzanlage zum Herstellen eines beliebigen Dickenprofils über die Breite eines bandförmigen Walzgutes beschrieben. Dabei wird das Ausgangsmaterial durch mehrere in Walzrichtung versetzt hintereinander angeordnete Walzen nahezu nur in Breitenrichtung verformt. Die Walzen ermöglichen eine entsprechend der gewünschten Profilierung örtlich gezielte Verformung, wobei die Eindringtiefe von der jeweiligen Anstellung der einzelnen schmalen Walzen oder Rollen abhängt. Das Ausgangsmaterial ist entweder ein Eisenwerkstoff oder ein NE-Metall; es kommt eine Kaltoder Warmverformung zum Einsatz.Furthermore, it is known not only to produce flat metal bands, but also those which have contours in the longitudinal and / or transverse direction. In DE 198 31 882 A1 a method and a rolling mill for producing an arbitrary thickness profile over the width of a strip-shaped rolling stock are described. In this case, the starting material is deformed by a plurality of rollers arranged one behind the other in the rolling direction almost only in the width direction. The rollers allow a locally targeted deformation according to the desired profiling, wherein the penetration depends on the respective employment of the individual narrow rollers or rollers. The starting material is either a ferrous material or a non-ferrous metal; It comes a cold or hot deformation used.
Aus der DE 199 62 754 A1 ist ein Verfahren zum flexiblen Walzen eines Metallbandes bekannt. Dieses Verfahren dient zur Herstellung von planen Metallbändern, die über ihrer Länge definiert unterschiedliche Banddicken aufweisen. Dabei wird während des Walzprozesses der Walzspalt gezielt verändert, um über die Länge des Metallbandes unterschiedliche Banddicken zu erzielen. Dies kann einerseits indirekt geschehen durch Veränderung des Verformungswiderstands des Materials durch Erwärmen oder Abkühlen des Metallbandes und entsprechend veränderte Auffederung des Walzgerüsts während des Walzvorgangs.From DE 199 62 754 A1 a method for flexible rolling of a metal strip is known. This method is used for the production of flat metal strips, which have different thicknesses defined over their length. In this case, the roll gap is selectively changed during the rolling process in order to achieve different strip thicknesses over the length of the metal strip. On the one hand, this can be done indirectly by changing the deformation resistance of the material by heating or cooling the metal strip and correspondingly changed springing of the roll stand during the rolling process.
Auch die EP 1 074 317 A2 betrifft ein Verfahren zum flexiblen Walzen eines Metallbandes, wobei das Metallband während des Walzprozesses durch einen zwischen zwei Arbeitswalzen gebildeten Walzspalt geführt und der Walzspalt während des Walzvorgangs gezielt verfahren wird, um über die Länge des Metallbandes unterschiedliche Banddicken zu erzielen. Hierbei werden während jedes Einstellens des Walzspalts oder unmittelbar danach die Biegelinien der Arbeitswalzen in Abhängigkeit vom eingestellten Walzspalt zur Erzielung einer Planheit des Metallbandes gesteuert.EP 1 074 317 A2 also relates to a method for flexibly rolling a metal strip, wherein the metal strip is guided during the rolling process through a nip formed between two work rolls and the nip is deliberately moved during the rolling process in order to achieve different strip thicknesses over the length of the metal strip , Here, during each setting of the roll gap or immediately thereafter, the bending lines of the work rolls are controlled depending on the set roll gap to achieve flatness of the metal strip.
Es ist die Aufgabe der Erfindung, ein Verfahren zum Aufwickeln eines Bandes, insbesondere eines ebenen oder eines mit Konturen versehenen, eines flexibel gewalzten und/oder eines profilgewalzten Metallbandes, derart zu verbessern, dass auf einfache Weise ein regelmäßiger wenigstens im wesentlichen zylinderförmiger Wickel erzeugt wird.It is the object of the invention to improve a method for winding a band, in particular a flat or contoured, a flexibly rolled and / or a profiled rolled metal strip, such that in a simple manner, a regular at least substantially cylindrical winding is produced ,
Erfindungsgemäß wird diese Aufgabe bei dem eingangs genannten Verfahren dadurch gelöst, dass die Anordnung Mittel zur Erzeugung eines nachgiebigen, insbesondere eines elastischen, Materials oder eines selbstquellenden oder aufschäumbaren Materials und zum Einbringen in den Wickel umfasst.According to the invention, this object is achieved in the aforementioned method in that the arrangement comprises means for producing a resilient, in particular an elastic material or a self-swelling or foamable material and for introduction into the winding.
Gemäß der Erfindung werden vor Ort entsprechend den Erfordernissen des aufzuwickelnden Bandes, d. h. unter Berücksichtigung seiner Oberflächenbeschaffenheit sowie der zu erwartenden Abweichung von der Rundheit des aufzuhaspelnden Wickels, die passenden Materialien eingesetzt, um eine elastische Substanz, insbesondere einen sich verfestigenden Schaum, zur Verfügung zu stellen, der in dem Maße in den Wickel eingebracht wird, dass ein vollständig oder nahezu runder Wickel entsteht. Damit ist die erfindungsgemäße Anordnung besonders für das Aufwickeln metallischer Spaltbänder, insbesondere aus Stahl, geeignet, aber auch für andere Bandmateriaiien, etwa aus Kunststoff, beispielsweise Duroplaste oder Thermoplaste. Die erfindungsgemäß als Einlage dienenden Materialien schonen die Bandoberflächen und verbessern die Wickelfähigkeit. Die Vorteile gleichmäßig gewickelter Wickel bestehen auch in der besseren Transportfähigkeit und in der Erleichterung der Weiterverarbeitung. Auch Änderungen in der Dicke des Bandes, sei es in Längs- oder in Querrichtung, lassen sich durch Änderung des Materialauftrags jederzeit ausgleichen.According to the invention, the appropriate materials are used on site in accordance with the requirements of the tape to be wound, ie taking into account its surface condition as well as the expected deviation from the roundness of the wound reel to provide an elastic substance, in particular a solidifying foam available , which is introduced into the winding to the extent that a completely or almost round winding is formed. Thus, the arrangement according to the invention is particularly suitable for winding metallic slit strips, in particular made of steel, but also for other tape materials, such as Plastic, for example thermosets or thermoplastics. The inventively serving as a liner materials protect the tape surfaces and improve the ability to wind. The advantages of uniformly wound coils also exist in the better transportability and in the ease of further processing. Even changes in the thickness of the strip, be it in the longitudinal or in the transverse direction, can be compensated at any time by changing the material order.
Vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.Advantageous developments of the invention will become apparent from the dependent claims.
Erfindungsgemäß wird mit Vorteil vorgesehen, dass das als Einlage dienende Material auf die jeweils oberste Lage des Wickels aufgerakelt oder aus nebeneinander in einer Reihe angeordneten Düsen auf die Oberfläche des Wickels aufgesprüht oder aufgespritzt wird. Das Material, also beispielsweise ein aufschäumbarer Kunststoff, lässt sich dabei auch über der Breite entsprechend der gewünschten Auftragstärke in unterschiedlicher Dicke und individuell über bestimmte Zonen in der Breite des Wickels aufsprühen. Auch im Falle des Aufra- kelns wird die Rakel entweder über die gesamte Breite des Wickels mit gleichem Abstand eingestellt, oder sie wird geneigt, bezogen auf die Drehachse des Wickels, eingestellt, um eine sich abzeichnende kegelförmige Aufwicklung des Wickels auszugleichen.According to the invention it is advantageously provided that the serving as a deposit material is aufgerakelt on the respective uppermost layer of the roll or sprayed from side by side in a row arranged nozzles on the surface of the roll or sprayed. The material, for example, a foamable plastic, can also be sprayed across the width according to the desired application thickness in different thicknesses and individually over certain zones in the width of the roll. Also in the case of scratching, the squeegee is either set equidistantly over the entire width of the reel, or it is adjusted inclined with respect to the axis of rotation of the reel, to compensate for an emerging conical winding of the reel.
Vorzugsweise erstreckt sich die Anordnung sich über die gesamte Breite des Wickels oder wenigstens über einen großen Teil der Breite des Wickels. Im letzteren Falle werden nur die kritischen Zonen überdeckt, in denen sich erfahrungsgemäß Ungleichmäßigkeiten verstärkt ausbilden.Preferably, the arrangement extends over the entire width of the roll or at least over a large part of the width of the roll. In the latter case, only the critical zones are covered, in which experience shows that irregularities are increased.
In einer weiteren vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass das Material in Streifen auf den Wickel aufgetragen wird. Diese Vorgehensweise dient einerseits dazu, mit möglichst wenig Zwischenlagematerial auszukommen, andererseits kann beim Aufbringen einer radial auf den Wickel einwirkenden Kraft das Material in die Bereiche zwischen den Streifen ausweichen, um auf diese Weise einen optimal runden Wickel zu erstellen.In a further advantageous embodiment of the invention, it is provided that the material is applied in strips on the winding. This procedure serves on the one hand to get along with as little as possible intermediate material, on the other hand, when applying a radial to the winding acting force the material in the areas between the strips evade to create in this way an optimally round winding.

Zur Erhöhung der Elastizität wird vorgesehen, dass der Kunststoff eine zusammenhängende Schicht oder eine Mehrzahl von in Bandlaufrichtung nebeneinanderliegenden Streifen auf dem Wickel bildet, die jeweils Lufteinschlüsse aufweisen. Beim Aufschäumen wird Luft oder ein anderes Gas entsprechend der gewünschten Elastizität in den aushärtenden Kunststoff eingebracht, um die Einlageschicht später entweder unter dem Eigengewicht des zu wickelnden Materials oder unter dem Einfluss einer radial wirkenden Anpresskraft zusammenzudrücken.To increase the elasticity, it is provided that the plastic forms a coherent layer or a plurality of strips adjacent to one another in the strip running direction on the winding, each of which has air inclusions. During foaming, air or another gas is introduced into the hardening plastic according to the desired elasticity in order to compress the insert layer later either under the dead weight of the material to be wound or under the influence of a radially acting contact pressure.
Um die Wirkung des Einbringens der Materialschicht noch weiter zu verbessern, lässt sich eine Messvorrichtung zur Messung der Banddicke des aufzuwickelnden Metallbandes integrieren, die die von ihr gemessenen Banddickenwerte an eine Regeleinrichtung weiterleitet. Diese gewinnt aus den die Banddicke wiedergebenden Signalen dann eine Regelgröße, um die Materialabgabe aus den Düsen, den Zusatz eines Aufschäummittels, von Luft, und dgl. entsprechend der gemessenen Banddicke des Metallbandes zu regeln oder im Falle einer Rakel deren Anstellung an die Wickelmantelfläche anzupassen.In order to further improve the effect of introducing the material layer, a measuring device for measuring the strip thickness of the metal strip to be wound up can be integrated, which passes on the strip thickness values it has measured to a control device. This wins from the signals representing the strip thickness then a controlled variable to regulate the delivery of material from the nozzles, the addition of a foaming agent, air, and the like. According to the measured strip thickness of the metal strip or adjust in the case of a doctor whose employment to the winding surface.
