Description

Die Erfindung betrifft eine Vorrichtung und ein Verfahren zum Handhaben eines Metallbandes. Die Vorrichtung umfasst insbesondere eine Haspeleinrichtung zum Aufwickeln des Metallbandes zu einem Coil und einen Bundausfahrwagen zum Übernehmen des Coils von der Haspeleinrichtung.The invention relates to an apparatus and a method for handling a metal strip. The device comprises, in particular, a reeling device for winding the metal strip into a coil and a bundle driving carriage for taking over the coil from the reeling device.

Im Stand der Technik sind zahlreiche Druckschriften bekannt, welche sich allgemein dem Thema der Handhabung von aufgewickelten Metallbändern widmen.In the prior art numerous publications are known, which are generally devoted to the topic of handling wound-up metal strips.

So ist aus der Deutschen Offenlegungsschrift DE 10 2007 051 976 A1 eine Haspelvorrichtung und ein Verfahren zur Fixierung der Coils bei der Haspelvorrichtung bekannt. Konkret offenbart die Offenlegungsschrift eine Haspelvorrichtung zum Aufwickeln von Warmband nach dem Walzen zu einem Coil. Weiterhin ist eine Einrichtung offenbart zur Herstellung einer Schweißverbindung, um das Ende des Metallbandes auf dem äußeren Umfang des Coils mit einer weiter innen liegenden Wicklung zu verschweißen. Auf diese Weise wird das Coil fixiert und an einem Aufspringen gehindert.Such is from the German publication DE 10 2007 051 976 A1 a reel device and a method for fixing the coils in the reel device known. Specifically, the publication discloses a reel device for winding hot strip after rolling into a coil. Furthermore, a device is disclosed for making a weld joint to weld the end of the metal strip on the outer circumference of the coil with a more inner winding. In this way, the coil is fixed and prevented from jumping on.

In der nicht vorveröffentlichten Patentanmeldung DE 10 2009 060 257.7 wird eine Auflage für ein Metallbund aus einer Haspeleinrichtung vorgeschlagen, wobei das Bund, englischsprachig auch Coil genannt, auf drei Auflagepunkten abgelegt wird. Ein Niederhalter zum Drücken des Coils auf die Auflagepunkte ist nicht offenbart; dies hat den Nachteil, dass hochfeste Metallbänder mit einer starken Neigung aufzuspringen, nicht unbedingt sicher auf den drei Auflagepunkten gelagert werden können.In the non-prepublished patent application DE 10 2009 060 257.7 a support for a metal collar from a reel device is proposed, wherein the federal government, also called coil in English, is deposited on three support points. A hold-down for pressing the coil on the support points is not disclosed; This has the disadvantage that high-strength metal bands with a strong tendency to jump, not necessarily be stored safely on the three support points.

Die Deutsche Offenlegungsschrift DE 10 2007 017 383 A1 offenbart eine Einrichtung zum Binden eines Coils, das sich auf einem drehangetriebenen Dorn befindet. Um auch bei einem aus dicken Bändern gehaspeltem Coil mit starker Aufspringtendenz eine sichere und zuverlässige Umgreifung zu ermöglichen, offenbart die Schrift, dass mindestens eine Andrück-Rolle vorgesehen ist mittels welcher vorgebogenes Flachstahlband um das Coil herumgeführt wird, um das Coil gegen Aufspringen zu sichern.The German Offenlegungsschrift DE 10 2007 017 383 A1 discloses a means for binding a coil located on a rotary driven mandrel. Even with a coiled from thick tapes coil with strong Aufspringtendenz to allow safe and reliable encasement, the document discloses that at least one pressure roller is provided by means of which pre-bent flat steel strip is passed around the coil to secure the coil against cracking.

Die Europäische Patentschrift EP 1 888 284 B1 offenbart eine Vorrichtung und ein Verfahren zur Entnahme einer Probe von einem Metallband, welches zu einem Coil aufgewickelt ist. Die erfindungsgemäße Vorrichtung sieht zwei Bodenrollen zur Lagerung eines Coils vor. Mindestens einer der Bodenrollen ist drehangetrieben ausgeführt. Das Bandende muss insbesondere bei höherfesten oder auch dicken Bändern stets durch eine der Rollen fixiert sein, um ein unerwünschtes Aufspringen des Bundes zu vermeiden. Neben den beiden Bodenrollen ist mindestens eine Andrückrolle vorgesehen, die das Coil an seiner Mantelfläche berührt und hinsichtlich seiner Lage fixiert. Eine der beiden Bodenrollen ist absenkbar ausgebildet und kann nach Fixierung des Coils durch die verbleibende Bodenrolle sowie die mindestens eine Andrückrolle von dem Coil weggeschwenkt werden. Durch das Wegschwenken der einen Bodenrolle verbleibt eine vergrößerte freie Bandlänge zwischen der verbleibenden Bodenrolle und der Andrückrolle, wodurch die lokale Deformation Bandendes geringer ist ohne dass dabei die Gefahr eines Aufspringens des Coils droht.The European patent EP 1 888 284 B1 discloses an apparatus and method for taking a sample from a metal strip wound into a coil. The device according to the invention provides two floor rolls for supporting a coil. At least one of the floor rolls is designed to be rotationally driven. The band end must always be fixed by one of the rollers, in particular for high-strength or thick bands, in order to avoid unwanted popping of the collar. In addition to the two bottom rollers at least one pressure roller is provided, which touches the coil on its lateral surface and fixed with respect to its position. One of the two bottom rollers is designed to be lowered and can be pivoted away from the coil after fixing the coil by the remaining bottom roller and the at least one pressure roller. By pivoting away the one bottom roller remains an increased free tape length between the remaining bottom roller and the pressure roller, whereby the local deformation tape end is lower without the risk of a springing of the coil threatens.

Dazu fahren die Bundausfahrwagen unter das Coil, wenn dieses in der Haspeleinrichtung auf dem Haspeldorn fertig aufgewickelt ist. Die typischerweise zwei Auflager des Bundausfahrwagens werden dann angehoben und von unten gegen das Coil auf dem Haspeldorn so angestellt, dass das Coil dann auf den beiden Auflagern aufliegt, nachdem der Haspeldorn entspreizt und/oder aus dem Auge des Coil zurückgezogen wurde. Der Bundausfahrwagen hat dabei zunächst die Aufgabe, das Ende des Metallbandes zu sichern, indem das Coil auf den beiden Auflagern so gedreht wird, dass das Bandende von dem Gewicht des Coils gegen die Auflager gedrückt wird. Nach einer derartigen Ablage des Coils auf dem Bundaus-fahrwagen wird das Coil mit Hilfe des Bundauftragswagens zu einer Coil-Bindeeinrichtung verbracht.In the production of hot strips, ie hot-rolled metal strips, on hot strip reels, the finished coils are conveyed out of the reel device at the end of the winding process with a coil conveyor. To drive the Bundausfahrwagen under the coil, if this in the reel is wound up on the coiler mandrel. The typically two supports of Bundausfahrwagens are then raised and employed from below against the coil on the coiler mandrel so that the coil then rests on the two supports, after the coiler mandrel despread and / or was withdrawn from the eye of the coil. The Bundausfahrwagen initially has the task to secure the end of the metal strip by the coil is rotated on the two supports so that the tape end is pressed by the weight of the coil against the supports. After such a filing of the coil on the Bundaus-trolley, the coil is spent using the federal contract carriage to a coil binding device.

Ein Trend bei konventionellen Warmbändern besteht in der Produktion von Metallbändern mit besonders hoher Festigkeit und Banddicke. Diese werden zur Herstellung von Röhrenstählen eingesetzt sowie für Verschleißoberflächen mit extremer Festigkeit. Werden diese Materialien aufgewickelt, so verbleibt in dem Coil eine Restspannung, welche das Ende des Metallbandes wieder öffnen will. Diese Tendenz steigt mit größerer Festigkeit und größerer Banddicke und tritt besonders bei kleinen Coils mit geringem Gewicht und geringem Durchmesser auf. Typische kleine Bunddurchmesser liegen bei 1000 mm bis 2300 mm.A trend in conventional hot strip is in the production of metal strips with particularly high strength and strip thickness. These are used to make tube steels and wear surfaces with extreme strength. When these materials are wound up, a residual stress remains in the coil, which tends to reopen the end of the metal strip. This tendency increases with greater strength and greater tape thickness, and is particularly noticeable in small, light weight and small diameter coils. Typical small collar diameters are 1000 mm to 2300 mm.

Bei derartigen besonderen Coils mit hoher interner Restspannung reicht das Coilgewicht oftmals nicht aus, um das Ende des Metallbandes bzw. das Coil auf den beiden Auflagern des Bundausfahrwagens zu sichern. Es besteht vielmehr die Gefahr, dass das Coil nicht mehr sicher von dem Haspeldorn gezogen und zur Abbindestation verbracht werden kann. Das Coil kann am Haspeldorn hängen bleiben, sich selbst von dem Bundausfahrwagen heben oder aufspringen.In such special coils with high internal residual stress, the coil weight is often not sufficient to secure the end of the metal strip or the coil on the two supports of Bundausfahrwagens. Rather, there is the danger that the coil can not be safely pulled from the coiler mandrel and spent to Abbindestation. The coil can get caught on the coiler mandrel, lift itself from the Bundausfahrwagen or jump up.

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Vorrichtung und ein Verfahren zum Handhaben eines Metallbandes dahingehend weiterzubilden, dass die Handhabung des Metallbandes, insbesondere eines Metallbandes mit hoher Restspannung, bei der Übergabe vom Haspeldorn auf den Bundausfahrwagen sowie während eines Transportes mit dem Bundausfahrwagen zusätzlich gegen Aufspringen gesichert wird.Based on this prior art, the present invention seeks to further develop a device and a method for handling a metal strip to the effect that the handling of the metal strip, in particular a metal strip with high residual stress in the transfer From the coiler mandrel on the Bundausfahrwagen and during transport with the Bundausfahrwagen additionally secured against cracking.

Diese Aufgabe wird durch den Gegenstand des Patentanspruchs 1 gelöst. Dieser ist gekennzeichnet durch einen zweiten Niederhaltearm zum Ausüben einer zweiten Niederhaltekraft F2 mit seinem Coil-seitigem Ende im Auge des Coils zum Drücken des Coils auf die Auflager des Bundausfahrwagens. Der erste Niederhaltearm ist ausgebildet, auf dem Umfang des Coils derart anzusetzen, dass die von ihm auf das Coil ausgeübte erste Niederhaltekraft F1 zumindest eine Komponente in Richtung der Gewichtskraft aufweist. Der zweite Niederhaltearm ist vorzugsweise ausgebildet, in dem Auge des Coils derart anzusetzen, dass die von ihm ausgeübte zweite Niederhaltekraft F2 zumindest eine Komponente in Richtung der Gewichtskraft aufweist.This object is solved by the subject matter of patent claim 1. This is characterized by a second hold-down arm for exerting a second hold-down force F2 with its coil-side end in the eye of the coil for pressing the coil onto the supports of the cuff carriage. The first hold-down arm is designed to set on the circumference of the coil such that the first hold-down force F1 exerted on the coil has at least one component in the direction of the weight force. The second hold-down arm is preferably designed to be positioned in the eye of the coil in such a way that the second hold-down force F2 exerted by it has at least one component in the direction of the weight force.

Durch das beanspruchte Vorsehen des Niederhaltearms wird eine Kraft mit zumindest einer Komponente in Richtung der Gewichtskraft in dem Auge des Coils ausgeübt, wodurch das Coil vorteilhafterweise an einem Aufspringen gehindert wird.By the claimed provision of the hold-down arm, a force is exerted with at least one component in the direction of the weight force in the eye of the coil, whereby the coil is advantageously prevented from popping up.

Grundsätzlich kann die Erfindung für Coils ohne interne Restspannung, mit kleiner Restspannung oder auch mit hoher Restspannung verwendet werden. Bei Coils ohne Restspannung oder mit nur geringer Restspannung wäre der erste Niederhaltearm zwar entbehrlich; allerdings ist es unschädlich, wenn dieser gemäß der vorliegenden Erfindung auch in diesen Fällen trotzdem vorgesehen ist. Der Niederhaltearm kann ausgebildet sein, eine aktive Andrückkraft auf den äußeren Umfang des Coils auszuüben. Alternativ kann der Niederhaltearm jedoch auch kraftlos aber in seiner Höhe fixiert an den äußeren Umfang des Coils angelegt sein. Bei kraftloser Anstellung ist die aktive Andrückkraft, gleichbedeutend mit der Niederhaltekraft, ausnahmsweise betraglich gleich Null. Eine (Gegen-)Kraft kann in diesem Fall dann entstehen, wenn das Coil versucht aufzuspringen, aber am Aufspringen durch den in seiner Höhe fest positionierten ersten Niederhaltearm gehindert wird.In principle, the invention can be used for coils without internal residual stress, with a small residual stress or even with a high residual stress. For coils without residual stress or with only low residual stress, the first hold-down arm would indeed be dispensable; However, it is harmless if this is still provided according to the present invention in these cases anyway. The hold-down arm may be configured to exert an active pressing force on the outer circumference of the coil. Alternatively, however, the hold-down can also be powerless but fixed in its height attached to the outer circumference of the coil. In powerless employment, the active pressure force, equivalent to the hold-down force, exceptionally amount equal to zero. A (counter) force can arise in this case when the coil tries to jump up, but is prevented from popping up by the first hold-down arm, which is firmly positioned in its height.

Definitionen:definitions:

Das Coil meint einen Bund bzw. Wickelbund aus flächigem Metallband, insbesondere metallischem Warmband, oder aus nichtflächigem Material, zum Beispiel Draht. Das Bund ist typischerweise aus Metall, zum Beispiel aus Stahl.The coil means a collar or winding band of flat metal strip, in particular metallic hot strip, or of non-surface material, for example wire. The collar is typically made of metal, for example steel.

Der Begriff "Handhabung eines Metallbandes" meint im Sinne der vorliegenden Erfindung insbesondere den Übertrag eines Coils von einem Haspeldorn auf einen Bundausfahrwagen und den Transport des Coils auf dem Bundausfahrwagen.The term "handling a metal strip" means in the context of the present invention, in particular the transfer of a coil from a coiler mandrel on a Bundausfahrwagen and the transport of the coil on the Bundausfahrwagen.

Die Auflager des Bundausfahrwagen können derart ausgebildet sein, dass ein punktförmiger, ein linienförmiger oder ein flächiger Kontakt mit dem abgelegten Coil entsteht.The supports of the Bundausfahrwagen can be designed such that a punctiform, a linear or a flat contact with the deposited coil is formed.

Gemäß einem ersten Ausführungsbeispiel umfasst die Vorrichtung zum Handhaben eines Metallbandes einen Ausleger, welcher über einem Wegverlauf für den Bundausfahrwagen angeordnet ist, eine Laufkatze zum Halten des Niederhaltearms und zum Verfahren des Niederhaltearms auf dem Ausleger und eine Synchronisierungseinrichtung zum Synchronisieren des Verfahrens der Laufkatze mit dem Niederhaltearm und des Bundausfahrwagens derart, dass der erste Niederhaltearm vorteilhafterweise während des Verfahrens des Bundausfahrwagens kontinuierlich an dem äußeren Umfang des Coils anliegt. Auf diese Weise wird vorteilhafterweise eine kontinuierliche Sicherung des Coils während des Transports auf dem Bundauftragswagen gewährleistet.According to a first embodiment, the device for handling a metal strip comprises a boom, which is arranged over a path for the Bundausfahrwagen, a trolley for holding the hold-down and for moving the hold-down on the boom and a synchronization device for synchronizing the process of the trolley with the hold-down and the curb carriage such that the first hold-down arm advantageously rests continuously against the outer circumference of the coil during the process of the cradle carriage. In this way, a continuous securing of the coil is ensured during transport on the federal order car advantageously.

Die Synchronisierungseinrichtung kann in Form einer elektrischen Steuerung oder in Form einer mechanischen Kopplung des coilseitigen Endes des Niederhaltearms an dem Coil ausgebildet sein. Der Ausleger ist zum Beispiel zumindest mit einem Ende ortsfest am oder im Bereich der Haspeleinrichtung verankert.The synchronization device may be in the form of an electrical control or in the form of a mechanical coupling of the coil-side end of the hold-down arm to the coil. The boom is, for example, at least one end anchored fixed on or in the field of reel.

Alternativ zum Verfahren des ersten Niederhaltearms mit einer Laufkatze entlang des Auslegers kann der erste Niederhaltearm mit seinem coilumfang-fernen Ende auch mechanisch an den Bundausfahrwagen angekoppelt sein.As an alternative to moving the first hold-down arm with a trolley along the boom, the first hold-down arm may also be mechanically coupled with its coil circumference-far end to the Bundausfahrwagen.

Der zweite Niederhaltearm kann an dem Bundausfahrwagen oder einem weiteren Bundwagen befestigt sein. Der weitere Bundwagen ist dann vorzugsweise ausgebildet, synchron mit dem Bundausfahrwagen, welcher das Coil trägt, zu verfahren.The second hold-down can be attached to the Bundausfahrwagen or another coil car. The further coil car is then preferably designed to move synchronously with the Bundausfahrwagen, which carries the coil.

Der erste und/oder zweite Niederhaltearm sind vorzugsweise in der Höhe verstellbar ausgebildet. Der erste und/oder der zweite Niederhaltearm können teleskopartig ein- oder ausfahrbar ausgebildet sein.The first and / or second hold-down arm are preferably adjustable in height. The first and / or the second hold-down arm can be formed telescopically extendable or retractable.

Die oben genannte Aufgabe wird weiterhin durch ein Verfahren zum Handhaben des Metallbandes gelöst. Die Vorteile dieses Verfahrens entsprechen grundsätzlich den oben mit Bezug auf die beanspruchte Vorrichtung genannten Vorteilen.The above object is further achieved by a method for handling the metal strip. The advantages of this method basically correspond to the advantages mentioned above with reference to the claimed device.

In besonders vorteilhafter Ausgestaltung sieht das erfindungsgemäße Verfahren vor, dass während des Austragens des Coils aus der Haspeleinrichtung der erste Niederhaltearm auf den äußeren Umfang des Coils einwirkt, wobei der erste Niederhaltearm synchron mit dem Coil und dem Bundausfahrwagen mit verfahren wird.In a particularly advantageous embodiment, the method according to the invention provides that, during the discharge of the coil from the reel device, the first hold-down arm acts on the outer circumference of the coil, wherein the first hold-down arm is moved in synchronism with the coil and the federal exit carriage.

Die Reichweite des ersten Niederhaltearms ist jedoch, insbesondere wenn er mit Hilfe einer Laufkatze entlang eines an der Haspeleinrichtung angeordneten Auslegers verfahren wird, begrenzt. Um auch bei einem Weitertransport des Coils über die Reichweite des ersten Niederhaltearms hinaus eine sichere Lagerung des Coils auf dem Bundausfahrwagen zu sichern, sieht das erfindungsgemäße Verfahren vor, dass mit Hilfe des zweiten Niederhaltearms eine zweite Niederhaltekraft in dem Auge des Coils aufgebracht wird zum Andrücken des Coils auf die Auflager des Bundausfahrwagens. Der zweite Niederhaltearm kann jedoch erst dann in das Auge des Coils hineinragen, nachdem das Coil mit Hilfe des Bundausfahrwagens zumindest ein Stück weit aus der Haspeleinrichtung ausgefahren und von dem Haspeldorn abgezogen wurde.The range of the first hold-down is, however, especially when it is moved by means of a trolley along a arranged on the reel boom, limited. In order to ensure safe storage of the coil on the Bundausfahrwagen also on further transport of the coil beyond the range of the first hold-down, the inventive method provides that with the help of the second hold-down a second hold-down force is applied in the eye of the coil for pressing the Coils on the supports of the Bundausfahrwagens. However, the second hold-down arm can only protrude into the eye of the coil after the coil has been extended with the help of Bundausfahrwagens at least a little way from the reel and pulled off the coiler mandrel.

Nachdem der zweite Niederhaltearm im Auge des Coils angreift, kann der ersten Niederhaltearm von dem äußeren Umfang des Coils entfernt werden, weil seine Funktion des Drückens des Coils auf die Auflager dann von dem zweiten Niederhaltearm übernommen wird.After the second hold-down arm engages the eye of the coil, the first hold-down arm can be removed from the outer circumference of the coil because its function of pressing the coil onto the supports is then taken over by the second hold-down arm.

Indem der zweite Niederhaltearm die Funktion des ersten Niederhaltearms übernimmt und damit das Coil auf dem Bundausfahrwagen sichert, kann das Coil auf dem Bundausfahrwagen auch nach außerhalb der Reichweite des ersten Niederhaltearms, zum Beispiel zu einer Bundbindemaschine, transportiert werden.By the second hold-down arm takes over the function of the first hold-down arm and thus secures the coil on the Bundausfahrwagen, the coil on the Bundausfahrwagen can also be transported out of reach of the first hold-down, for example to a waistband machine.

Wenn der zweite Niederhaltearm mit seinem coil-fernen Ende auf einem weiteren Bundwagen verankert bzw. befestigt ist, ist es erforderlich, sicherzustellen, dass der weitere Bundwagen synchron mit dem Bundausfahrwagen mit verfährt, um die zweite Niederhaltekraft F2 in dem Auge des Coils kontinuierlich aufrecht zu erhalten während eines Weitertransports des Coils.If the second hold-down arm is anchored or fastened with its coil-far end on a further coil car, it is necessary to ensure that the further coil carriage moves synchronously with the Bundausfahrwagen, to continuously maintain the second hold down force F2 in the eye of the coil during further transport of the coil.

Nach einem Sichern des Coils durch Verschweißen seines Bandendes oder Abbinden in einer Bundbindemaschine kann auch der zweite Niederhaltearm aus dem Auge des Coils entfernt werden.After securing the coil by welding its band end or setting in a waistband binding machine, the second hold-down arm can also be removed from the eye of the coil.

Wie bereits oben ausgeführt, eigenen sich die erfindungsgemäße Vorrichtung und das erfindungsgemäße Verfahren vorzugsweise zur Handhabung von Coils mit hoher Restspannung, die zum Aufspringen neigen. Allerdings ist die Erfindung nicht auf derartige Coils beschränkt, sondern kann grundsätzlich auch bei Coils ohne Aufspringrisiko angewandt werden. Im Hinblick auf seine bevorzugte Verwendung sieht das erfindungsgemäße Verfahren vor, vor Anwendung des Verfahrens zunächst zu prüfen, ob für das handzuhabene Coil ein Aufspringrisiko aufgrund einer internen höheren Restspannung gegeben ist. Vorzugsweise wird das erfindungsgemäße Verfahren zur Handhabung des Coils lediglich dann vorgesehen, wenn das zuvor ermittelte Aufspringrisiko für das Coil einen vorgegebenen Schwellenwert übersteigt. Das Aufspringrisiko kann physikalisch bewertet werden in Abhängigkeit der Festigkeit des Metallbandes, der Banddicke und des Gewichtes bzw. des Durchmessers des handzuhabenen Coils. Konkret können die genannten physikalischen Parameter jeweils mit einem vorgegebenen Schwellenwert verglichen werden und es kann das Aufspringrisiko für das Coil dadurch als gegeben definiert werden, wenn zumindest einzelne der Schwellenwerte überschritten werden.As already stated above, the device according to the invention and the method according to the invention are preferably suitable for handling coils with a high residual stress, which tend to crack. However, the invention is not limited to such coils, but in principle can also be applied to coils without Aufspringrisiko. With regard to its preferred use, the method according to the invention provides, before using the method, first of all to check whether there is a risk of a risk of springing up due to an internal higher residual stress for the coil to be handled. Preferably, the method according to the invention for handling the coil is provided only if the previously determined risk of collapse for the coil exceeds a predetermined threshold value. The risk of collapse can be physically evaluated depending on the strength of the metal strip, the strip thickness and the weight or diameter of the hand-held coil. Specifically, the stated physical parameters can each be compared with a predetermined threshold value, and the risk of the coil starting up can be defined as given if at least some of the threshold values are exceeded.

Konkret kann das Aufspringrisiko dann festgestellt werden, wenn die Schwellenwerte für die Dicke und die Festigkeit des Metallbandes überschritten und der Schwellenwert für den Durchmesser des Coils gleichzeitig unterschritten wird.Specifically, the risk of collision can be determined if the threshold values for the thickness and the strength of the metal strip are exceeded and the threshold for the diameter of the coil is simultaneously undershot.

Weitere vorteilhafte Ausgestaltungen der erfindungsgemäßen Vorrichtung und des erfindungsgemäßen Verfahrens sind Gegenstand der abhängigen Ansprüche.Further advantageous embodiments of the device according to the invention and of the method according to the invention are the subject of the dependent claims.

Die Erfindung wird nachfolgend unter Bezugnahme auf die genannten Figuren in Form von Ausführungsbeispielen detailliert beschrieben. In allen Figuren sind gleiche technische Elemente mit gleichen Bezugszeichen bezeichnet.The invention will be described in detail below with reference to the said figures in the form of embodiments. In all figures, the same technical elements are designated by the same reference numerals.

Figur 1 zeigt die erfindungsgemäße Vorrichtung 100 gemäß einem ersten Ausführungsbeispiel. Demnach umfasst die Vorrichtung 100 zum Handhaben eines Metallbandes eine Haspeleinrichtung 110 mit einem Haspeldorn 112 zum Aufwickeln des Metallbandes zu einem Coil 200. Das Coil 200 ist in Figur 1 aufgewickelt auf dem Haspeldorn 112 gezeigt. FIG. 1 shows the device 100 according to the invention according to a first embodiment. Accordingly, the apparatus 100 for handling a metal strip comprises a coiler 110 with a coiler mandrel 112 for winding the metal strip to a coil 200. The coil 200 is in FIG. 1 wound on the coiler mandrel 112 shown.

Weiterhin umfasst die erfindungsgemäße Vorrichtung 100 einen Bundausfahrwagen 120, welcher in Figur 1 beispielhaft auf einem ortsfesten Schienenverlauf 122 verfahrbar gelagert ist. Der Bundausfahrwagen 120 umfasst beispielsweise zwei Auflager 124 zum Aufnehmen des Coils 200 von dem Haspeldorn 112. Zu diesem Zweck werden die in ihrer Höhe 124 gegenüber dem Schienenverlauf 122 verstellbaren Auflager 124 von unten vertikal gegen die untere Hälfte des Coils 200 angestellt. In dieser Hubtigelstellung wird das Coil 200 von den Auflagern des Bundausfahrwagens in seiner Höhe gehalten. Optional kann zusätzlich zu den Auflagern auch ein Schwenkarm an dem Bundausfahrwagen vorgesehen sein, welcher insbesondere das Ende des Metallbandes von unten, das heißt, entgegen der Schwerkraft gegen das Coil drückt und auf diese Weise das Coil auf dem Bundausfahrwagen zusätzlich stabilisiert. Der Haspeldorn 112 wird dann kollabiert oder entspreizt, so dass er den Kontakt mit dem inneren Auge des Coils 200 verliert. Der Bundausfahrwagen 120 zieht dann das Coil 200 in eingefrorener Hubtigelstellung von dem Haspeldorn 112 ab und fährt es aus der Haspeleinrichtung aus.Furthermore, the device 100 according to the invention comprises a Bundausfahrwagen 120, which in FIG. 1 by way of example is movably mounted on a stationary rail track 122. The Bundausfahrwagen 120 includes, for example, two supports 124 for receiving the coil 200 of the coiler mandrel 112. For this purpose, the adjustable in height 124 against the track 122 supports 124 are made vertically from below against the lower half of the coil 200. In this lifting position, the Coil 200 is held by the supports of the Bundausfahrwagens in height. Optionally, in addition to the supports also a swivel arm may be provided on the Bundausfahrwagen, which presses in particular the end of the metal strip from below, that is, against the force of gravity against the coil and in this way additionally stabilizes the coil on the Bundausfahrwagen. The coiler mandrel 112 is then collapsed or despread so that it loses contact with the inner eye of the coil 200. The Bundausfahrwagen 120 then pulls the coil 200 in frozen Hubtigelstellung of the coiler mandrel 112 and drives it out of the reel.

Um insbesondere bei Coils mit hoher Restspannung ein Aufspringen der Coils in der Haspeleinrichtung zu verhindern, ist erfindungsgemäß ein erster Niederhaltearm 130 vorgesehen zum Ausüben einer ersten Niederhaltekraft F1 auf den äußeren Umfang des Coils 200. Der Niederhaltearm dient zum Andrücken des Coils auf die Auflager des Bundausfahrwagens. Gemäß dem in Figur 1 gezeigten ersten Ausführungsbeispiel ist der erste Niederhaltearm 130 mit seinem coil-fernen Ende 132 mit einer Laufkatze 135 verbunden und mit Hilfe dieser Laufkatze entlang eines Auslegers 133 verfahrbar. Der Ausleger 133 ist über dem Schienenverlauf 122 vorzugsweise in konstanter Höhe H angeordnet und zum Beispiel mit einem Ende im Bereich oder an der Haspeleinrichtung 110 befestigt.In order to prevent the coils in the coiling device, especially in coils with high residual stress, according to the invention, a first hold-down arm 130 is provided for exerting a first hold-down force F1 on the outer circumference of the coil 200. The hold-down arm serves to press the coil onto the supports of the federal extension carriage , According to the in FIG. 1 shown In the first exemplary embodiment, the first hold-down arm 130 is connected with its coil-distal end 132 to a trolley 135 and can be moved along a boom 133 with the aid of this trolley. The extension arm 133 is arranged above the track 122, preferably at a constant height H, and fastened, for example, with one end in the area or on the reel device 110.

Eine erfindungsgemäße Synchronisierungseinrichtung 140, vorzugsweise in Form einer elektronischen Steuerung, ist ausgebildet, dass Verfahren der Laufkatze mit dem ersten Niederhaltearm 130 mit dem Verfahren des Bundwagens 120 mit dem Coil 200 derart zu synchronisieren, dass der erste Niederhaltearm 130 während des Ausfahrens des Coils 200 aus der Haspeleinrichtung 110 kontinuierlich am äußeren Umfang des Coils 200 anliegt. Zu diesem Zweck muss die Laufkatze 135 mit dem ersten Niederhaltearm 130 synchron mit dem Bundausfahrwagen 120 und dem Coil 200 verfahren werden. Sollte der Abstand, zum Beispiel die Höhe H, zwischen dem Ausleger 133 und dem Schienenverlauf 122 entlang des Verlaufes des Auslegers variieren, so muss die Synchronisierungseinrichtung 140 zusätzlich ausgebildet sein, diese variierenden Abstände auszugleichen, in dem der erste Niederhaltearm 130 zum Beispiel in seiner Höhenposition gegenüber der Laufkatze 135 entsprechend variabel angepasst bzw. höhenverstellt wird.A synchronization device 140 according to the invention, preferably in the form of an electronic control, is configured to synchronize the method of the trolley with the first hold-down arm 130 with the process of the bundle carriage 120 with the coil 200 such that the first hold-down arm 130 during the extension of the coil 200 from the reel device 110 rests continuously on the outer circumference of the coil 200. For this purpose, the trolley 135 must be moved with the first hold-down arm 130 in synchronism with the Bundausfahrwagen 120 and the coil 200. Should the distance, for example the height H, between the boom 133 and the track 122 vary along the path of the boom, then the synchronizer 140 must additionally be configured to compensate for these varying distances, in which the first hold-down arm 130 is in its height position, for example relative to the trolley 135 is variably adjusted or adjusted in height accordingly.

Alternativ zu einer Ausbildung der Synchronisierungseinrichtung in Form einer elektronischen Steuerung, kann die Synchronisierungseinrichtung auch vereinfacht in Form einer mechanischen Kopplung des coilseitigen Endes des ersten Niederhaltearmes 130 an dem äußeren Umfang des Coils 200 ausgebildet sein. Das coilseitige Ende des ersten Niederhaltearms wird dann von dem Coil selber geführt. Die mechanische Ankopplung des coil-fernen Endes 132 des ersten Niederhaltearms an der Laufkatze ist dann so zu gestalten, dass die Ausübung der ersten Niederhaltekraft F1 auf das Coil gewährleistet bleibt.As an alternative to a design of the synchronization device in the form of an electronic control, the synchronization device can also be designed in the form of a mechanical coupling of the coil-side end of the first hold-down arm 130 on the outer circumference of the coil 200 in a simplified manner. The coil-side end of the first hold-down arm is then guided by the coil itself. The mechanical coupling of the coil-far end 132 of the first hold-down arm on the trolley is then to be designed so that the exercise of the first hold-down force F1 is ensured on the coil.

Figur 2 zeigt das auf den Auflagern 124 des Bundausfahrwagens 120 abgelegte Coil 200 bei Einwirkung der ersten Niederhaltekraft F1 auf den äußeren Umfang des Coils 200 gemäß dem in Figur 1 gezeigten Betriebszustand der erfindungsgemäßen Vorrichtung. Das Auge des Coils 200 ist in Figur 2 mit dem Bezugzeichen 210 bezeichnet. Bei dem in Figur 1 gezeigten Betriebszustand ist dieses Auge mit dem Haspeldorn 112 ausgefüllt. FIG. 2 shows the deposited on the supports 124 of the Bundausfahrwagens 120 coil 200 upon application of the first hold down force F1 on the outer circumference of the coil 200 according to the in FIG. 1 shown operating state of the device according to the invention. The eye of the coil 200 is in FIG. 2 designated by the reference numeral 210. At the in FIG. 1 shown operating state of this eye is filled with the coiler mandrel 112.

Figur 3 zeigt die erfindungsgemäße Vorrichtung gemäß dem ersten Ausführungsbeispiel in einem zweiten späteren Betriebszustand im Vergleich zu Figur 1. Das Coil 200 ist bei dem in Figur 3 gezeigten späteren Betriebszustand bereits mit Hilfe des Bundausfahrwagens ein Stück weit aus der Haspeleinrichtung ausgefahren. Der Haspeldorn 112 gibt jetzt bereits einen Teil des Auges 210 des Coils 200 frei zum Einführen eines zweiten Niederhaltearms 150. Der zweite Niederhaltearm ist bei dem in Figur 3 gezeigten ersten Ausführungsbeispiel auf einem weiteren Bundwagen 160 montiert. Alternativ kann der zweite Niederhaltearm 150 jedoch auch auf dem Bundausfahrwagen 120 montiert sein. FIG. 3 shows the device according to the invention according to the first embodiment in a second later operating state compared to FIG. 1 , The coil 200 is at the in FIG. 3 shown later operating state with the help of Bundausfahrwagens extended a bit far from the reel. The coiler mandrel 112 now already releases part of the eye 210 of the coil 200 for insertion of a second hold-down arm 150. The second hold-down arm is at the in FIG FIG. 3 shown first embodiment mounted on a further coil car 160. Alternatively, however, the second hold down arm 150 may also be mounted on the crab carriage 120.

Wichtig ist, dass der erste Niederhaltearm 130 immer noch auf den äußeren Umfang des Coils 200 einwirkt, um das Coil auf dem Bundausfahrwagen zu sichern, während der zweite Niederhaltearm in das Auge 210 eingeführt wird.Importantly, the first hold down arm 130 still acts on the outer circumference of the coil 200 to secure the coil on the cradle carriage while the second hold down arm is inserted into the eye 210.

In Figur 3 ist die Laufkatze 135 am Ende des Auslegers 133 angelangt; das heißt bei dem in Figur 3 gezeigten Betriebszustand ist das Ende der Reichweite des ersten Niederhaltearms 130 erreicht. Für einen Weitertransport des Coils wird der erste Niederhaltearm 130 vom Umfang des Coils 200 abgehoben, nachdem der zweite Niederhaltearm 150 im Auge 210 des Coils die zweite Niederhaltekraft F2 ausübt zum Andrücken des Coils 200 auf die Auflager 124 des Bundausfahrwagens 120. Die erste und die zweite Niederhaltekraft F1, F2 sind jeweils größer bemessen als die drohende Aufspringkraft des Coils. Beide Niederhalterkräfte sind zum Bespiel betraglich gleich groß.In FIG. 3 the trolley 135 has reached the end of the boom 133; that is at the in FIG. 3 shown operating state, the end of the range of the first hold-down arm 130 is reached. For further transport of the coil, the first hold-down arm 130 is lifted off the circumference of the coil 200 after the second hold-down arm 150 in the eye 210 of the coil exerts the second hold-down force F2 for pressing the coil 200 onto the supports 124 of the cradle 120. The first and second Hold-down force F1, F2 are each dimensioned larger than the imminent spring-up force of the coil. Both hold-down forces are the same size for example.
