Abstract

1. A loop roller table (1-17) with rollers to accommodate the wire loops deposited by the loop layer (18) for cooling and conveying to a coil forming station (19), the roller table having at least two main driven sections (1 - 14 and 15-17), characterised by : the first roller table section (1 - 14) featuring rolls which can be driven synchronously and the second roller table section (15 - 17) comprising rollers with overrunning clutches capable of being driven individually or in grouped combination.

Description

Die Erfindung betrifft einen Windungstransportrollgang gemäß dem Oberbegriff des Patentanspruchs 1 sowie ein Betriebsverfahren für diesen Rollgang.The invention relates to a winding conveyor roller table according to the preamble of claim 1 and an operating method for this roller table.

Der aus dem letzten Walzgerüst eines Drahtfertigblockes austretende Draht wird im allgemeinen zunächst mit Wasser gekühlt. Mit Hilfe eines Legerohres (dem Windungsleger) werden dann aufrechtstehende bzw. leicht nach vorn geneigte Windungen geformt, die im ausgefächerten Zustand auf einen horizontalen Transportrollgang fallen.The wire emerging from the last rolling stand of a wire finishing block is generally first cooled with water. With the help of a laying tube (the winding layer), upright or slightly forward-inclined windings are formed, which in the fanned out state fall onto a horizontal transport roller table.

Dort folgt eine gezielte metallurgische Abkühlung des Drahtes.There is a targeted metallurgical cooling of the wire.

Aus metallurgischen Gründen wird bei verschiedenen Materialqualitäten eine langsame Abkühlgeschwindigkeit (1°C/sec) gefordert.For metallurgical reasons, a slow cooling rate (1 ° C / sec) is required for different material qualities.

Um diese Werte zu erzielen, muß der Transportrollgang beim Sammeln der Windungen sehr langsam fahren, d. h. die walzwarmen Windungen werden zu einem relativ hohen Paket gelegt. Die so gebildeten Pakete werden anschließend mit konstanter Transportgeschwindigkeit durch einen allseits geschlossenen, isolierten Rollgang gefahren und abgekühlt.In order to achieve these values, the transport roller table must move very slowly when collecting the turns, i. H. the warm whale coils are laid in a relatively high package. The packets thus formed are then moved and cooled at a constant transport speed through an insulated roller table that is closed on all sides.

Am Ende des Rollganges werden dann die Windungspakete über eine oder mehrere Stufen fallen gelassen, gelockert und durch nachfolgende schneller laufende Fördersysteme auseinandergezogen (Verringerung der Pakethöhe) um die Windungspakete in die nachfolgende Bundsammeleinrichtung einbringen zu können. Bei dieser Fahrweise entsteht der Nachteil, daß die Walzpausen (normalerweise 5 sec). um ein Mehrfaches vergrößert werden müssen und dabei erhebliche Produktionseinbußen entstehen. Die Vergrößerung der Walzpause ist notwendig weil in der üblichen Walzpause das gebildete Windungspaket nur eine ca. 500 mm große Lücke zum Windungsleger bilden würde. Die Lücke muß jedoch mindestens 1.800 mm betragen.At the end of the roller table, the winding packages are then dropped over one or more steps, loosened and pulled apart by subsequent faster-running conveyor systems (reduction in the package height) in order to be able to introduce the winding packages into the subsequent bundle collecting device. The disadvantage of this procedure is that the rolling breaks (normally 5 seconds). have to be increased many times over, resulting in considerable production losses. The enlargement of the roll break is necessary because in the usual roll break the winding package formed would only form an approx. 500 mm gap to the winding layer. However, the gap must be at least 1,800 mm.

Diese Lücke ist nötig, damit die einzelnen Windungspakete nicht ineinander gelegt werden und ein problem- und störungsloses Sammeln der einzelnen Bunde an der Bundsammeleinrichtung möglich ist.This gap is necessary so that the individual winding packages are not placed one inside the other and that the individual bundles can be collected without problems and without problems at the bundle collecting device.

Aufgabe der Erfindung ist es, den eingangs genannten Rollgang so auszubilden, daß eine Verkürzung der Pausenzeiten und damit eine Produktionserhöhung möglich ist.The object of the invention is to design the roller table mentioned at the outset in such a way that a shortening of the break times and thus an increase in production is possible.

Gelöst wird diese Aufgabe erfindungsgemäß durch die im Anspruch 1 angegebenen Merkmale sowie das Betriebsverfahren gemäß Anspruch 4.This object is achieved according to the invention by the features specified in claim 1 and the operating method according to claim 4.

Vorzugsweise Ausgestaltungen ergeben sich aus den Unteransprüchen.Refinements preferably result from the subclaims.

Die synchrone Beschleunigung des ersten Rollgangabschnittes ermöglicht es eine Lücke von ca. 1.800 mm zu fahren ohne Erhöhung der Pausenzeiten wie dies nachfolgend anhand der Systenskizze erläutert werden soll.The synchronous acceleration of the first roller table section makes it possible to drive a gap of approx.1,800 mm without increasing the break times, as will be explained below using the system sketch.

Der erfindungsgemäße Windungstransportrollgang besteht aus zwei Hauptabschnitten, und zwar dem ersten Abschnitt mit den einzelnen Abschnitten 1 bis 14 und dem zweiten Rollgangabschnitt mit den einzelnen Abschnitten 15 bis 17.The winding transport roller table according to the invention consists of two main sections, namely the first section with the individual sections 1 to 14 and the second roller table section with the individual sections 15 to 17.

Der Windungsleger ist mit 18, die Bundsammeleinrichtung mit 19 und die Kühleinrichtungen sind mit 20 bezeichnet.The winding layer is 18, the coil collecting device 19 and the cooling devices 20.

Der Windungsleger legt wie bisher die Drahtwindungen auf den langsam laufenden Transportrollgang, auf welchem so ein Windungspaket gebildet wird.As before, the winding layer places the wire windings on the slow-moving transport roller table on which such a winding package is formed.

Sobald das Ende einer Walzlänge den Windungsleger verlassen hat, wird der Rollgang-Abschnitt 1 - 14 auf eine Geschwindigkeit beschleunigt, mit der in der üblichen Walzpause eine Lücke von ca. 1.800 mm gefahren wird.As soon as the end of a roll length has left the winding layer, the roller table section 1-14 is accelerated to a speed at which a gap of approx. 1,800 mm is traveled during the usual roll break.

Die Rollgangabschnitte 1 - 14 fahren synchron. Sobald der neue Stabkopf den Windungsleger erreicht, fährt der Rollgang wieder mit Sammelgeschwindigkeit.The roller table sections 1 - 14 move synchronously. As soon as the new rod head reaches the winding layer, the roller table moves again at collecting speed.

Die Rollgangabschnitte 15 - 17 fahren mit erhöhter Geschwindigkeit gegenüber Sammelgeschwindigkeit (50-100 % über Vsammel), so daß während der Walz- bzw. Legezeit eine größere Lücke zwischen den Paketen im Bereich Abschnitt 14/15 gebildet wird.The roller table sections 15-17 travel at increased speed compared to the collecting speed (50-100% over Vsammel), so that a larger gap is formed between the packages in the area section 14/15 during the rolling or laying time.

Bei beschleunigter Fahrweise der Abschnitte 1 - 14 wird das Windungspaket was sich auf Abschnitt 14 befand mit erhöhter Geschwindigkeit auf Abschnitt 15 geschoben.When sections 1-14 are accelerated, the winding package which was on section 14 is pushed onto section 15 at an increased speed.

Die Rollen in Abschnitt 15 werden über ihre Nenndrehzahl beschleunigt, eingebaute Freiläufe in jeder Rolle der Abschnitte 15 und 16 ermöglichen ein Aufschieben des Paketes ohne Schlupf oder Materialbeschädigung.The rollers in section 15 are accelerated via their nominal speed, built-in freewheels in each roller of sections 15 and 16 enable the package to be pushed on without slippage or material damage.

Das aufgehobene Windungspaket kann nicht mit dem vorherlaufenden Paket kollidieren, da durch die in der Sammelzeit schneller laufenden Rollgangabschnitte 15 - 17 eine ausreichend große Lücke gebildet wurde. ,The reversed winding package cannot collide with the preceding package, since a sufficiently large gap was formed by the roller table sections 15-17 running faster in the collection time. ,

Erreicht ein Windungspaket mit Sammelgeschwindigkeit den Rollgangsabschnitt 15, der mit 50 - 100 % Vorlauf arbeitet, wird sobald genügend Gewichtsanteil des Windungspaketes sich auf Abschnitt 15 befindet,"das Paket auf Vorlaufgeschwindigkeit beschleunigt.If a winding package with collecting speed reaches the roller table section 15, which works with 50-100% advance, as soon as there is sufficient weight portion of the winding package on section 15, "the package is accelerated to the forward speed.

Die Rollen in den Abschnitten 13 und 14 sind ebenfalls mit Freiläufen ausgerüstet und ermöglichen so ein Beschleunigen des Windungspaketes auf Vorlaufgeschwindigkeit ohne Schlupf oder Material beschädigung. Das Windungspaket kann dabei als starrer Körper angesehen werden und beschleunigt die Rollen auf seine jeweilige Geschwindigkeit, welches durch die in den Abschnitten 13 bis 16 eingebauten Freiläufe ermöglicht wird.The rollers in sections 13 and 14 are also equipped with freewheels and thus enable the winding package to be accelerated to the forward speed without slippage or material damage. The winding package can be viewed as a rigid body and accelerates the rollers to their respective speeds, which is made possible by the freewheels installed in sections 13 to 16.

Bei dieser Fahrweise werden die Windungspakete immer mit gleicher Geschwindigkeit Über eine Stufe an ein nachfolgendes schneller laufendes Fördersystem übergeben.With this mode of operation, the winding packages are always transferred at the same speed to a subsequent faster-running conveyor system.
