Abstract

The invention relates to an apparatus for winding and unwinding rolled strip (WB) discharging from a mill train (WS), in which apparatus the rolled strip (WB) discharging from the mill train (WS) is introduced by a set of bending rolls (BR) into a winding chamber (WK) having a rotationally driven roller pair (RP) and is wound into a coil (WB), and the coil is then put onto a roller table (GR) and unwound from these rollers with the direction of rotation being reversed and the start of the strip is fed to a driver device (RT). The apparatus is improved by a supporting slide (TS) which can be pushed into the winding chamber (WK) and in whose side walls a pivoted lever (SH) is mounted, the free end of which carries a pressure roller (AR) which can be put onto the rolled strip coil and pushes the latter out of the winding chamber (WK) onto the adjoining roller table (GR).

Description

Die Erfindung betrifft eine Vorrichtung zum Auf- und Abwickeln von Walzbändern, bei der das aus der Walzstraße austretende Band von einem Satz von Biegewalzen erfasst, in eine drehangetriebene Rollen aufweisende Wickelkammer eingebracht, zu einem Bund gewickelt und der Bund anschließend auf einen Rollgang aufgebracht und unter Drehrichtungsumkehr der Rollgangsrollen wieder abgewickelt und der Bandanfang einer Treibeinrichtung zugeführt wird.The invention relates to a device for winding and unwinding of rolled strips, in which detects the emerging from the rolling train of a set of bending rolls, introduced into a rotary driven rollers having winding chamber, wound into a bundle and then applied the federal government on a roller table and below Direction of rotation of the roller table rolls unwound again and the beginning of the tape is fed to a drive device.

Aus der JP 2000 15 80 41 ist eine Vorrichtung bekannt bei der der gewickelte Bund aus der Wickelposition mit Hilfe von zwei Andruckrollen in eine Abwickelposition geführt wird. Diese beidseitige Führung verhindert ein Weiterrollen des Bundes.From the JP 2000 15 80 41 a device is known in which the wound collar is guided from the winding position by means of two pinch rollers in an unwinding position. This two-sided leadership prevents a continuation of the federal government.

Bei einer bekannten Vorrichtung dieser Art WO 03/013753 wird das von den Blegerollen vorgebogene Band einer mehrere angetriebene Rollen aufweisende Wickelkammer zugeführt, und die tragenden Rollen werden, nachdem das Band zu einem Bund gewickelt wurde, gemeinsam in die Rollgangsebene eingebracht und ermöglichen in dieser Position den Weitertransport des gewickelten Bundes aus der Wickelposition heraus auf eine nachgeordnete, angetriebene Rollen aufweisende Trageinrichtung. Diese Trageinrichtung ist in Bandbewegungsrichtung verschiebbar und ermöglicht durch Drehrichtungsumkehr ihrer Rollen das Abwickeln des aufliegenden Bundes unter anschließender Einführung des Bandanfangs in eine nachgeordnete Treibereinrichtung. Ein weiterer bekannt gewordener Vorschlag ( EP PS 933 147 ) geht dahin, zwei hintereinander angeordnete Paare von Tragrollen für den gewickelten Bund vorzusehen, die in auf einander zu und voneinander weg bewegbaren Kipprahmen gelagert sind und es erlauben, den jeweils gewickelten Bund aus der Wickelposition in eine Abwickelposition einzubringen.In a known device of this type WO 03/013753 For example, the band pre-bent by the lead rollers is fed to a winding chamber having a plurality of driven rollers, and the supporting rollers, after the band has been wound into a bundle, are jointly introduced into the roller gangway and allow in this position the further transport of the wound collar out of the winding position a downstream, powered rollers having carrying means. This support device is displaceable in the direction of tape movement and allows by reversing the direction of their roles, the unwinding of the overlying federal with subsequent introduction of the beginning of the tape in a downstream driver device. Another known proposal ( EP PS 933 147 ) Goes to provide two successively arranged pairs of support rollers for the wound collar, in on each other and from each other are stored movable tilting frame and allow to bring each wound coil from the winding position in an unwinding position.

Bei diesen Vorrichtungen ergeben sich Schwierigkeiten beim Transport des Bundes von den tragenden Tragrollen der Wickelkammer auf die Rollen der nachgeordneten Weitertransporteinrichtung. Weil dieser Transport jeweils vom Stillstand des Bundes in der Wickelkammer ausgeht und weil der Bund neben der Transportbewegung zusätzlich mit der Abwickeldrehung beginnt.In these devices, difficulties arise in the transport of the Federal of the supporting idlers of the winding chamber on the roles of downstream transport device. Because this transport emanates from the stoppage of the Federal in the winding chamber and because the federal government in addition to the transport movement additionally begins with the unwinding rotation.

Die Erfindung schlägt deshalb vor, den Bund aus der Wickelkammer heraus auf einen der Wickelkammer nachgeordneten Rollgangsabschnitt zu schieben, dessen Transportebene an die Auflageebene der Wickelkammer winkelanstellbar ist. Diese Verschiebung des Bundes wird erfindungsgemäß durch einen Schwenkhebel bewirkt, der in den Seitenwänden eines in die Wickelkammer einschiebbaren Tragschlittens angeordnet, an seinem freien Ende eine Druckrolle trägt. Diese Druckrolle liegt auf dem Umfang des Bundes auf und schiebt diesen beim Schwenken des Schwenkhebels aus der Wickelkammer heraus auf den nachgeordneten Rollgangsabschnitt. Anschließend wird nach Einbringen des nächstfolgenden Bundes in die Wickelkammer der Schwenkhebel wieder in seine Ausgangslage zurückgeschwenkt und die Druckrolle auf diesen Bund aufgelegt.The invention therefore proposes to push the federal government out of the winding chamber out onto a roller conveyor section arranged downstream of the winding chamber, the transport plane of which being angularly adjustable to the support plane of the winding chamber. This displacement of the collar is effected according to the invention by a pivot lever which is arranged in the side walls of a sliding into the winding chamber support carriage, carries at its free end a pressure roller. This pressure roller rests on the circumference of the collar and pushes it when pivoting the pivot lever out of the winding chamber out on the downstream roller table section. Subsequently, after introducing the next federal in the winding chamber, the pivot lever is swung back to its original position and placed the pressure roller on this federal government.

Das Walzband wird aus der Walzstraße herangeführt über eine Biegerollenanordnung BR in die Wickelkammer WK eingeführt und dort auf einem Rollenpaar RP mit leicht geneigter Rollenebene aufliegend zu einem Bund B gewickelt. An dieses Rollenpaar RP schließt sich ein Gruppenrollgang an, dessen Rollenebene R der Rollen der Wickelkammer WK leicht entgegengeneigt verläuft und mit Hilfe eines Stellmotors SM neigungsverstellbar ist. Diesem Gruppenrollgang GR nachgeordnet ist ein Richttreiberaggregat RT.The rolled strip is introduced from the rolling train via a bending roller assembly BR introduced into the winding chamber WK and there wound on a pair of rollers RP with slightly inclined roller level lying on a bunch B. This roller pair RP is followed by a group roller table whose roller plane R of the rollers of the winding chamber WK runs slightly counter-inclined and is adjustable in inclination with the aid of a servomotor SM. Subordinate to this group roller table GR is a straightening unit RT.

In die Wickelkammer WK ist ein Tragschlitten TS einfahrbar, in dessen Seitenwänden, oberhalb des Walzbandbundes WB ein Schwenkhebel SH angelenkt ist, der an seinem freien Ende eine Andruckrolle AR trägt, die auf den Umfang des Bundes auflegbar ist. Wie aus Fig. 1 in Verbindung mit Fig. 2 ersichtlich, wird der in der Wickelkammer WK gewickelte Bund B mit Hilfe dieses Schwenkhebels SH durch die Andruckrolle AR aus der Wickelkammer WK heraus auf den Gruppenrollgang GR geschoben und auf diesem aufliegend mit Hilfe der an dem Richttreiber RT angeordneten Lenkrolle LR diesem zugeführt.
