Description
Die Erfindung betrifft ein Verfahren zum Coupieren der Anfangswindungen und/oder Endwindungen eines Drahtbundes im Zuge des Ausfächerns von zu Drahtbunden zusammenzulegendem Walzwerk hinter dem Fertigblock einer Drahtwalzstraße, - mit den Merkmalen aus dem Oberbegriff des Patentanspruches 1.The invention relates to a method for coupling the initial windings and / or end windings of a wire bundle in the course of fanning out the rolling mill to be bundled behind the finished block of a wire rolling mill, with the features from the preamble of patent claim 1.
Walzt man in einem modernen Drahtwalzwerk Draht aus einem Knüppel oder Block, so erhält man nach Maßgabe des Blockgewichtes und der Drahtdicke einen Draht vorgegebener Länge, jedoch kann, insbesondere beim Walzen ohne Zug nicht verhindert werden, daß am Anfang und/oder am Ende ein Drahtabschnitt entsteht, der den Qualitätsanforderungen und/oder Dickentoleranzanforderungen nicht genügt und abgeschnitten werden muß. Dieses Abschneiden wird im Rahmen der Erfindung als Coupieren bezeichnet. Es wird regelmäßig durchgeführt, wenn der Draht bereits zu Windungen ausgefächert ist. Es versteht sich, daß zwischen Fertigblock und dem Windungsleger eine Wasserkühlstrecke angeordnet sein kann. Die Kühlung auf dem Hauptförderer ist im allgemeinen, aber nicht notwendigerweise, eine gesteuerte Kühlung mit metallurgischen Zielen. Das Coupieren erfolgt mit geeigneten Hilfsvorrichtungen, wird aber auch heute noch von Hand durchgeführt. In einem Drahtbund, das dem Markt zugeführt wird, muß der Draht vom Anfang bis zum Ende den Qualitätsanforderungen und Toleranzen entsprechen. Das Coupieren muß entsprechend genau und trotz der hohen Walzgeschwindigkeit moderner Drahtwalzwerke störungsfrei erfolgen. Es versteht sich, daß die erforderlichen Messungen dem Coupieren vorgeschaltet sind und die Meßergebnisse beim Coupieren berücksichtigt werden.If you roll wire from a billet or block in a modern wire rolling mill, you get a wire of specified length depending on the block weight and the wire thickness, however, especially when rolling without tension, it cannot be prevented that a wire section at the beginning and / or at the end arises, which does not meet the quality requirements and / or thickness tolerance requirements and must be cut off. This cutting is referred to as couping in the context of the invention. It is carried out regularly when the wire is already fanned out into turns. It goes without saying that a water cooling section can be arranged between the prefabricated block and the winding layer. The cooling on the main conveyor is generally, but not necessarily, controlled cooling with metallurgical purposes. Coupling is carried out with suitable auxiliary devices, but is still carried out by hand today. In a bundle of wires that is brought to the market, the wire must meet the quality requirements and tolerances from start to finish. Couping must be carried out accordingly accurately and in spite of the high rolling speed of modern wire rolling mills. It is understood that the required measurements are upstream of the coupé and the measurement results are taken into account when couping.
Für die bekannten Maßnahmen ist zunächst wesentlich, daß die Kühlung auf dem Hauptförderer werkstoff- und produktbezogen so erfolgt, daß der fertig behandelte gebündelte Draht die vorgegebenen Qualitätsparameter ausreichend genau aufweist. Insoweit kommt es auf das Maß der Behandlungsfächerung und die Hauptfördergeschwindigkeit an. Es versteht sich, daß die Behandlungsausfächerung und die Hauptfördergeschwindigkeit, produktbezogen, unterschiedlich eingestellt werden. Im einzelnen ist in diesem Zusammenhang und zu den auftretenden Problemen folgendes zu bemerken:
Es ist bekannt, an Drahtwalzstraßen den Draht nach der Walzung mit dem Windungsleger auszufächern und auf einem bewegten Förderer abzulegen. Von dem Förderer werden die Windungen auf einen Sammeldorn geworfen. Dort wird das Drahtbund gesammelt, abtransportiert, gepreßt und für den Transport gebunden. Dieser Förderer ist im Sinne der Erfindung der Hauptförderer. Auf dem Hauptförderer erfolgt üblicherweise die schon angesprochene Kühlung des Drahtes (vgl. US 32 31 432). Von den Windungen, die zu einem Drahtbund zusammengefaßt werden, müssen die Anfangswindungen und Endwindungen, denen z.B. eine Drahtlänge von bis zu 5 m entspricht, abgeschnitten werden. Beim Walzen von Draht, der auf dem Hauptförderer mit Luft vergütet wird, müssen vom Anfang bei Beginn eines Walzvorganges sogar 20 bis 30 m abgeschnitten werden, weil zu Beginn eines Walzvorganges eine Wasserkühlung vor dem Ablegen des Drahtes in Windungen auf dem Hauptförderer noch nicht möglich ist. Dieses Abschneiden wird von Hand durchgeführt, entweder während der Draht auf dem Hauptförderer liegt oder nach dem Sammeln des Bundes, jedoch vor dem sogenannten Kompaktieren und Binden, dem die Drahtbunde üblicherweise unterworfen werden. Die beschriebenen Maßnahmen sind sehr arbeitsaufwendig und verursachen hohe Personalkosten. Hinzu kommt, daß es sich um eine anstrengende, heiße und wenig angenehme Arbeit handelt, wobei häufig auch unexakt gearbeitet wird.For the known measures, it is first of all essential that the cooling on the main conveyor takes place in a material and product-related manner in such a way that the finished treated bundled wire has the specified quality parameters with sufficient accuracy. In this respect, it depends on the size of the treatment fan and the main conveying speed. It goes without saying that the treatment fan and the main conveying speed, depending on the product, are set differently. The following should be noted in this context and regarding the problems that arise:
It is known to fan out the wire on the wire rolling mill after the rolling with the winding layer and to deposit it on a moving conveyor. The turns are thrown onto a collecting mandrel by the conveyor. There the bundle of wires is collected, transported away, pressed and bound for transport. In the sense of the invention, this conveyor is the main conveyor. The cooling of the wire already mentioned usually takes place on the main conveyor (cf. US 32 31 432). From the windings, which are combined to form a wire bundle, the initial windings and end windings, for example a wire length of up to 5 m, must be cut off. When rolling wire that is air-conditioned on the main conveyor, 20 to 30 m must be cut from the beginning at the start of a rolling process, because at the start of a rolling process, water cooling is not yet possible before the wire is deposited in turns on the main conveyor . This cutting is done by hand, either while the wire is on the main conveyor or after collecting the bundle, but before so-called compacting and bandaging to which the wire bundles are usually subjected. The measures described are very labor intensive and cause high personnel costs. In addition, it is a strenuous, hot and uncomfortable job, although work is often inexact.
Es ist vorgeschlagen worden, die beschriebenen Maßnahmen automatisch durchzuführen (japanische Patentanmeldung 58-195202, japanische Offenlegung 60-87923). Es handelt sich dabei um einen neben dem Hauptförderer des ausgefächerten Drahtes in Transportrichtung des Drahtes verfahrbaren Automaten, der am Anfang und Ende des jeweiligen Bundes eine bestimmte Zahl von Windungen abschneidet, aufnimmt und abtransportiert. Diese Maßnahmen haben in die Praxis bisher wenig Eingang gefunden, weil sie störanfällig sind. Die Störungen beruhen darauf, daß der Windungsleger nicht völlig gleichmäßig arbeitet. Insbesondere bei dünnen Drahtabmessungen unter 7 mm Durchmesser ist dieses der Fall. Schwankungen beim Austritt der Windungen aus dem Windungsleger führen dazu, daß Windungen auf dem Förderer von einer voreilenden Windung "überholt" werden. Das bedeutet, daß eine Windung, die mit gegenüber der Sollgeschwindigkeit erhöhter Geschwindigkeit aus dem Windungsleger austritt, vor dem Auftreffen auf den Hauptförderer in Transportrichtung gleichsam weiter fliegt und vor einer vorher aus dem Windungsleger ausgetretenen Windung zu liegen kommt. Das hat zur Folge, daß der beschriebene Automat zwar die gewünschte Windung abschneiden kann, jedoch ein Abtransport der Windung nicht möglich ist, da sie durch die vorgeeilte Windung festgehalten wird. Die Lösung dieses Problems wird dadurch erschwert, daß bestimmte Qualitäten auf dem Hauptförderer aus metallurgischen Gründen sehr langsam abkühlen müssen und deshalb die Windungen so dicht wie möglich auf dem Hauptförderer gelegt werden. In einem solchen Falle ist ein Überholen der Windungen besonders leicht möglich. - Die Präzision des Arbeitens eines Windungslegers so zu verbessern, daß das beschriebene Überholen nicht eintritt, ist bisher nicht gelungen.It has been proposed to automatically perform the measures described (Japanese Patent Application 58-195202, Japanese Laid-Open 60-87923). In addition to the main conveyor of the fanned-out wire, it is an automatic machine which can be moved in the direction of transport of the wire and which cuts, picks up and transports a certain number of turns at the beginning and end of the respective coil. These measures have so far been little used in practice because they are prone to failure. The disturbances are due to the fact that the winding layer does not work completely evenly. This is particularly the case with thin wire dimensions of less than 7 mm in diameter. Fluctuations in the emergence of the turns from the lay-up layer mean that turns on the conveyor are "overtaken" by a leading turn. This means that a turn, which emerges from the winding layer at a speed which is higher than the set speed, continues to fly in the transport direction before it hits the main conveyor and comes to rest in front of a winding which has previously exited the winding layer. The result of this is that the automat described can cut off the desired turn, but it is not possible to remove the turn because it is held in place by the forward turn. The solution to this problem is complicated by the fact that certain qualities on the Main conveyors have to cool down very slowly for metallurgical reasons and therefore the turns are placed as close as possible on the main conveyor. In such a case, it is particularly easy to overtake the turns. - Up to now, it has not been possible to improve the precision of the work of a winding layer so that the overtaking described does not occur.
Bei einem Verfahren der eingangs beschriebenen Gattung (GB-A-1 246 049) wird nicht die Transportgeschwindigkeit der an den Windungsleger anschließenden und die Windungen aufnehmenden Transporteinrichtung gesteuert, sondern die Transportgeschwindigkeit des Hauptförderers, und zwar abschnittsweise in einem der Coupiereinrichtung zugeordneten Bereich. Die aus dem Windungsleger austretenden Windungen werden mit einer vorgegebenen, stets gleichbleibenden Ausfächerung - nämlich der Behandlungsausfächerung - abgelegt. Mit der Behandlungsausfächerung werden die Windungen an den Hauptförderer übergeben. Im Bereich der Coupiereinrichtung gelangen die Windungen auf eine Beschleunigungsstrecke, wobei die Windungen gestreckt und auseinandergezogen werden. Dabei können nach wie vor die oben erläuterten Probleme und Störungen auftreten, weil nicht verhindert werden kann, daß manche Windungen voreilen und vor einer vorher aus dem Windungsleger ausgetretenen Windung auf dem Hauptförderer aufliegen. Es kommt zu einer Unordnung, die noch verstärkt wird, wenn die Windungen die Beschleunigungsstrecke im Bereich der Coupiereinrichtung erreichen.In a method of the type described at the beginning (GB-A-1 246 049), it is not the transport speed of the transport device which adjoins the winding layer and which receives the windings that is controlled, but rather the transport speed of the main conveyor, in sections in an area assigned to the coupling device. The turns emerging from the winding layer are deposited with a predetermined, always constant fan-out - namely the treatment fan-out. With the treatment fan out, the turns are transferred to the main conveyor. In the area of the coupling device, the windings reach an acceleration section, the windings being stretched and pulled apart. The problems and faults explained above can still occur because it cannot be prevented that some windings advance and lie on the main conveyor in front of a winding that previously emerged from the winding layer. A disorder occurs, which is exacerbated when the turns reach the acceleration section in the area of the coupling device.
Der Erfindung liegt die Aufgabe zugrunde, das gattungsgemäße Verfahren so zu führen, daß das Coupieren der Anfangswindungen und/oder Endwindungen und der Abtransport der abgeschnittenen Anfangswindungen bzw. Endwindungen ohne Schwierigkeiten erfolgen kann. Der Erfindung liegt fernerhin die Aufgabe zugrunde, eine Anlage anzugeben, mit der das erfindungsgemäße Verfahren besonders einfach durchgeführt werden kann.The invention has for its object to perform the generic method so that the coupling of the initial turns and / or end turns and the removal of the cut Initial turns or end turns can be done without difficulty. The invention is furthermore based on the object of specifying a system with which the method according to the invention can be carried out in a particularly simple manner.
Diese Aufgabe wird gelöst mit einem Verfahren nach dem Patentanspruch 1. Vorteilhafte Ausgestaltungen sind in den Ansprüchen 2 und 3 angegeben. Es versteht sich, daß im Rahmen der Erfindung das Coupieren auch von Hand ausgeführt werden kann.This object is achieved with a method according to claim 1. Advantageous refinements are specified in
Erfindungsgemäß wird die Ausfächerung der Windungen durch die Geschwindigkeit des Rollganges gesteuert. Dabei werden die Anfangswindungen und Endwindungen mit einer Coupierausfächerung abgelegt, die größer ist als die Behandlungsausflächerung der den späteren Drahtbund bildenden Bindungen. An der Übergabestelle zwischen dem Windungsleger und dem Förderer wird also Sorge dafür getragen, daß die Windungen, in deren Bereich das Coupieren erfolgen wird, mit einer ausreichend großen Ausfächerung abgelegt werden. Es wird verhindert, daß die beschriebenen Unordnungen in kritischen Bereichen überhaupt auftreten können. Andererseits erlaubt das erfindungsgemäße Verfahren, die Windungen, welche den späteren Drahtbund bilden, sehr dicht auf dem Förderer auszulegen, was aus metallurgischen Gründen gewünscht wird.According to the invention, the spreading of the windings is controlled by the speed of the roller table. The initial windings and end windings are deposited with a coupling fan that is larger than the treatment surface of the bonds that later form the wire bundle. At the transfer point between the winding layer and the conveyor, care is therefore taken to ensure that the turns, in the area of which the couping will take place, are deposited with a sufficiently large spread. It is prevented that the described disorder can occur in critical areas at all. On the other hand, the method according to the invention allows the windings which form the subsequent wire bundle to be laid out very tightly on the conveyor, which is desired for metallurgical reasons.
Gegenstand der Erfindung ist auch eine Anlage zur Durchführung des erfindungsgemäßen Verfahrens, wie sie im Anspruch 4 gekennzeichnet ist.The invention also relates to a plant for carrying out the method according to the invention, as characterized in claim 4.

Sie besteht im Ausführungsbeispiel aus einer Wasserkühlstrecke 2, einem Windungsleger 3 für den Draht, einem Rollgang 4, auf dem man die ausgefächerten Drahtwindungen 5 erkennt, einem Hauptförderer 6 und einem Sammeldorn 7, für die Aufnahme der Windungen 5 von einem zu bildenden Drahtbund 8. Die Anordnung ist so getroffen, daß der Hauptförderer 6 mit einer vorgegebenen produktabhängig einrichtbaren Hauptfördergeschwindigkeit arbeitet. Diese ist in den Fig. 1 und 2 durch einen Pfeil angedeutet worden. Es versteht sich, daß der Hauptförderer einen entsprechenden Antrieb aufweist, der nicht gekennzeichnet wurde. Der vorgeschaltete Rollgang 4 hat einen eigenen Antrieb. Er ist zum Zwecke des Coupierens von Anfangswindungen und Endwindungen eines Drahtbundes 8 auf dem Hauptförderer 6 mit einer Rollgangsgeschwindigkeit antreibbar, die größer ist als die jeweils eingerichtete Hauptfördergeschwindigkeit. Der Abschneideautomat 9 ist bei Fig. 2 angedeutet. Im übrigen ist die Anordnung so getroffen, daß diese erhöhte Rollgangsgeschwindigkeit auf die Hauptfördergeschwindigkeit umgeschaltet werden kann. Es ist ein Rechner vorgesehen, der den Rollgang nach Maßgabe des durchzuführenden Coupierens gemäß Programm- und/oder Meßdaten steuert, was nicht gezeichnet wurde. Der Rollgang 4 wird bei Austritt der Anfangswindungen 5 und/oder Endwindungen 5 eines zu bildenden Drahtbundes 8 aus dem Windungsleger 3 mit einer Rollgangsgeschwindigkeit betrieben, die größer ist als die Hauptfördergeschwindigkeit. Der Rollgang 4 wird auf die Hauptfördergeschwindigkeit umgeschaltet, sobald oder bevor die erste der mit Coupierausfächerung ausgelegten Windungen den Hauptförderer erreicht hat, so daß die mit Coupierausfächerung ausgelegten Windungen 5 dem Hauptförderer übergeben werden. Sie liegen in der Reihenfolge der Herstellung im Windungsleger. Die abzuschneidenden Windungen können mit dem Schneidautomaten 9, ohne sich zu verhaken, leicht und sauber abgetrennt werden.The system shown in the figures for carrying out the method according to the invention works behind the finishing block 1 of a wire rolling mill, which adjoins on the left.
