Definitions
- the invention relates to a collar transfer device, in particular for transporting metal coils in a coil box.
- a coil box is a band reeling device which initially bends the metal strip coming from the roughing train by means of rotationally driven bending rolls, so that it winds up in a winding trough formed by supporting rolls to form a metal collar.
- the band end becomes the band head of the subsequent finish rolling process. As long as the metal collar is in this winding position, the coil box can not accept another tape.
- the transfer should be as gentle as possible, otherwise damage to the outer layer of the metal collar may occur if, for example, it strikes hard against a stop.
- the metal collar which usually has a mass of about 10 to 40 t and a relatively high temperature, from about 900 ° C to 1100 ° C, take damage on its outer turn. A piece on the outer circumference is then scrap.
- the transfer of the metal collar takes place on carrier rollers, the employment of which is predetermined successively with respect to the transport plane in such a way that a roller table depression advancing in the transport direction is formed.
- the result is a Bewowungs-sequence that resembles a "wandering wave" and moves the metal collar in a "wave valley”.
- the metal collar is alternately supported by two or three support rollers. In this case, the federal government is supported in a first fret position by means of two arranged on a first frame part support rollers.
- the collar is moved out of this position by tilting and lowering this frame part at the same time.
- a smooth transition to the subsequent in the transport direction roller table is possible.
- the active transfer between the support by two or three support rollers can be made very gentle by appropriate control of the drives. As a result, only relatively small forces act on the outer circumference of the collar and the risk of damage is lower.
- a stable position of the waistband can be achieved if the waistband is supported in alternating sequence by two or three idlers during the transfer.
- FIGS. 1 to 7 illustrated sequence of a collar transfer process explained in more detail.
- like reference numerals designate the same or similar components.
- a metal collar 4 can be seen, which is located in a winding position 5 of a coil box, not shown.
- This coil box is arranged between a roughing mill and a finishing mill of a rolling mill.
- the coil box is used for winding and unwinding of the belt 2.
- the coming of the Vorstrasse metal strip 2 may have a temperature of the usual way about 900 - 1100 ° C; the fully wound metal collar 4 usually has a mass of about 10 to 40 t.
- the metal collar 4 is continuously unwound. In this case, the metal collar 4 rolls in each case with its outer turn at the bottom side arranged ground or support rollers 11, 12, 13, 14, 15 from.
- the support rollers 11, 12 are arranged on a common frame part 29.
- the support rollers 13 and 14 each on an associated pivot arm.

- the tape head of the tape 2 is already supplied to a driver or a finishing mill, not shown.
- the method according to the invention provides an approach for a gentle transfer of the metal bundle in the coil box.
- the collar transfer takes place by coordinated adjustment of the axes of adjacent support rollers 11, 12, 13, 14 whereby a progressing in the transfer direction 8 "wave trough" is formed, which forms a Abwickelmulde 32 for the unwinding collar 4.
- the two support rollers 11, 12 are mounted on a cross member of a first frame member 29 and rotationally driven.
- the first frame part 29 consists of a crosspiece and a longitudinal piece.
- the crosspiece and the longitudinal piece are rigidly interconnected.
- the longitudinal piece of the first frame part 29 is articulated on the end to a second frame part 30.
- the first frame part 29 and the second frame part 30 together form the support frame 7.
- the support frame 7 acts as an angle lever: both the first frame part 29 and the second frame part 30 are each pivotable about an associated pivot axis 25 and 26 (in the drawings of the FIG. 1 to FIG. 7 the drives are omitted for clarity).
- the two rollers 11 and 12 in two degrees of freedom can be adjusted.
- a constellation is shown in which the two support rollers 11, 12 form an upwardly open trough by their distance from each other, in which the metal collar 4 is received in a stable position.

Like from the FIG. 2 can be seen, this tilting and lowering takes place by the first frame member 29 is pivoted in the direction of arrow 18 about the axis of rotation 25, and at the same time the second frame member in the direction of the arrow 17 is pivoted downwards. Due to the force of gravity and the onset of strip tension 3, the metal collar 4 begins to move in the direction of transfer 8. The support roller 13 limits this movement for now. The metal collar 4 is now again stable in a unwinding trough 32, which with respect to the in FIG. 1 a little further to the left. The three rollers 11, 12 and 13 carry the metal collar 4 in this position. The transition to this position was gentle and without unduly high force on the lateral surface of the Federation. 4
- the first support roller 13 is now pivoted in the direction of the arrow 19 about the axis 27 down, which again due to gravity, the sideways movement of the metal collar 4 in FIG. 3 is continued until the metal collar 4 gently comes to rest in the unwinding trough 32 formed thereby ( FIG. 3 ). In this position, now support two support rollers the metal collar 4, namely the first support roller 13 and the outlet-side support roller 12 of the support frame. 7
- FIG. 5 Now shows a scenario after a continuation of this principle.
- the lateral movement is supported by pivoting up the first carrying roller 13 in the direction of the arrow 23.

- the principle of moving a progressive floor sink has the advantage that the metal collar is constantly in a trough, that is in a stable position.
- the transfer of the metal collar 4 of support roller to support roller can be done comparatively gently by appropriate employment of the support rollers.
- each of the rollers 11, 12, 13, 14 is rotationally driven.
- the peripheral speed is set so that no slip occurs between the speed of the belt 2 and the rotational movement of the roller.
- the speed of rotation of the roller also takes into account the linear speed component resulting from the pivoting movement of the roller.

Description
Die Erfindung betrifft eine Bundtransfereinrichtung, insbesondere zum Transport von Metallbunde in einer Coilbox.The invention relates to a collar transfer device, in particular for transporting metal coils in a coil box.
In der Walzwerktechnik ist ein Anlagentyp bekannt, bei dem ein von einer Vorstraße kommender Vorstreifen in einer so genannten Coilbox zu einem Bund aufgewickelt wird und anschließend zur weiteren Verarbeitung abgewickelt und einer Fertigstraße zugeführt wird. Eine Coilbox ist eine Bandhaspeleinrichtung, welche zunächst das von der Vorstrasse kommende Metallband mittels drehangetriebener Biegerollen biegt, so dass es sich in einer durch Stützrollen gebildeten Aufwickelmulde zu einem Metallbund aufwickelt. Wenn der Metallbund fertig gewickelt ist, wird das Bandende zum Bandkopf des darauf sich anschließenden Fertigwalzprozesses. Solange sich der Metallbund in dieser Aufwickelposition befindet, kann die Coilbox kein weiteres Band aufnehmen.In rolling mill technology, an installation type is known in which a preliminary strip coming from a roughing street is wound up into a coil in a so-called coil box and then unwound for further processing and fed to a finishing train. A coil box is a band reeling device which initially bends the metal strip coming from the roughing train by means of rotationally driven bending rolls, so that it winds up in a winding trough formed by supporting rolls to form a metal collar. When the metal band is finished wound, the band end becomes the band head of the subsequent finish rolling process. As long as the metal collar is in this winding position, the coil box can not accept another tape.
Um einen möglichst großen Materialdurchsatz zu gewährleisten, wird daher der Abwickelvorgang bereits begonnen, wenn sich der Metallbund noch in seiner Aufwickelposition befindet. Man versucht möglichst rasch diesen Platz freizumachen, um den nächsten herannahenden Vorstreifen aufwickeln zu können. Um diesen Platz zu schaffen, ist in der Coilbox eine Lageveränderung des Bundes von der Aufwickelposition in eine in Richtung der Fertigwalstraße liegende Abwickelposition erforderlich.In order to ensure the largest possible material throughput, therefore, the unwinding process is already started when the metal collar is still in its winding position. One tries to clear this place as quickly as possible in order to be able to wind up the next approaching strip. In order to create this space, a change in the position of the Federal from the winding position into a unwinding position lying in the direction of the finishing whale is required in the coil box.
Da der Metallbund in der Coilbox aufgrund seiner Temperatur leicht verformbar ist, soll der Transfer möglichst sanft verlaufen, da es sonst zur Beschädigung der äußeren Lage des Metallbundes kommen kann, wenn dieser beispielsweise hart gegen einen Anschlag auftrifft.Since the metal collar in the coil box is easily deformed due to its temperature, the transfer should be as gentle as possible, otherwise damage to the outer layer of the metal collar may occur if, for example, it strikes hard against a stop.
Aus der
In der
Dabei kann der Metallbund, der üblicherweise eine Masse von etwa 10 bis 40 t und eine relativ hohe Temperatur, von etwa 900°C bis 1100°C aufweist, an seiner äußeren Windung Schaden nehmen. Ein Stück am äußeren Umfang ist dann Schrott.In this case, the metal collar, which usually has a mass of about 10 to 40 t and a relatively high temperature, from about 900 ° C to 1100 ° C, take damage on its outer turn. A piece on the outer circumference is then scrap.
Es ist eine Aufgabe der Erfindung ein Verfahren zum Transfer eines Metallbundes anzugeben, mit dem ein möglichst schonender Transfer möglich ist, so dass wenig Ausschussmaterial anfällt und das darüber hinaus zuverlässig funktioniert.It is an object of the invention to provide a method for transferring a metal collar, with which a transfer that is as gentle as possible is possible, so that little scrap material is produced and that moreover functions reliably.
Diese Aufgabe wird durch ein Verfahren mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Ansprüchen definiert.This object is achieved by a method having the features of
Gemäß einem Grundgedanken der vorliegenden Erfindung erfolgt der Transfer des Metallbundes auf Tragrollen, deren Anstellung bezüglich der Transportebene sukzessive so vorgegeben wird, dass sich eine in Transportrichtung fortschreitende Rollgangsenke ausbildet. Das Anstellen der jeweiligen Tragrollen erfolgt mittels zugeordneter Schwenkantriebe, z. B. eines Hydraulikzylinders. Es entsteht eine Beweaungs-Abfolge die einer "wandernden Welle" ähnelt und den Metallbund in einem "Wellental" mitbewegt. Während des Transfervorgangs ist der Metallbund abwechselnd von zwei oder von drei Tragrollen gestützt. Dabei wird der Bund in einer ersten Bundposition mittels zweier auf einem ersten Rahmenteil angeordneten Tragrollen gestützt. Der Bund wird aus dieser Position heraus bewegt, indem dieses Rahmenteil gleichzeitig gekippt und abgesenkt wird. Dadurch ist ein sanfter Übergang auf den sich in Transportrichtung anschließenden Rollgang möglich. Die aktive Übergabe zwischen der Stützung durch zwei beziehungsweise drei Tragrollen kann dabei durch entsprechende Steuerung der Antriebe sehr sanft gestaltet werden. Damit wirken auf den äußeren Umfang des Bundes vergleichsweise nur geringe Kräfte ein und die Gefahr der Beschädigung ist geringer.According to a basic idea of the present invention, the transfer of the metal collar takes place on carrier rollers, the employment of which is predetermined successively with respect to the transport plane in such a way that a roller table depression advancing in the transport direction is formed. The hiring of the respective support rollers by means of associated part-turn actuators, z. B. a hydraulic cylinder. The result is a Bewowungs-sequence that resembles a "wandering wave" and moves the metal collar in a "wave valley". During the transfer process, the metal collar is alternately supported by two or three support rollers. In this case, the federal government is supported in a first fret position by means of two arranged on a first frame part support rollers. The collar is moved out of this position by tilting and lowering this frame part at the same time. As a result, a smooth transition to the subsequent in the transport direction roller table is possible. The active transfer between the support by two or three support rollers can be made very gentle by appropriate control of the drives. As a result, only relatively small forces act on the outer circumference of the collar and the risk of damage is lower.
Eine stabile Lage des Bunds erreicht man, wenn der Bund während des Transfers in abwechselnder Reihenfolge von zwei oder von drei Tragrollen gestützt wird.A stable position of the waistband can be achieved if the waistband is supported in alternating sequence by two or three idlers during the transfer.
Um die Oberfläche des Bandes nicht zu beschädigen, ist es günstig, wenn die Umfangsgeschwindigkeit einer jeden in Berührung mit dem Band liegenden Rolle der Bandgeschwindigkeit entspricht.In order not to damage the surface of the belt, it is favorable if the peripheral speed of each roller in contact with the belt corresponds to the belt speed.
Zur weiteren Erläuterung der Erfindung wird im nachfolgenden Teil der Beschreibung an Hand eines nicht einschränkenden Ausführungsbeispiels auf die Zeichnungen Bezug genommen, aus denen weitere vorteilhafte Ausgestaltungen, Einzelheiten und Weiterbildungen der Erfindung zu entnehmen sind. Dargestellt sind jeweils zeitlich hintereinander liegende Konstellationen während des Transfers des Metallbundes.To further explain the invention, reference is made in the following part of the description with reference to a non-limiting embodiment of the drawings, from which further advantageous embodiments, details and further developments of the invention can be found.

Wie im Folgenden gezeigt wird, schafft das erfindungsgemäße Verfahren einen Ansatz für einen schonenden Transfer des Metallbundes in der Coilbox.As will be shown below, the method according to the invention provides an approach for a gentle transfer of the metal bundle in the coil box.
Gemäß der Erfindung erfolgt der Bundtransfer durch aufeinander abgestimmtes Anstellen der Achsen benachbarter Tragrollen 11, 12, 13, 14 wodurch ein in Transferrichtung 8 fortschreitendes "Wellental" gebildet wird, welches für den sich abwickelnden Bund 4 eine Abwickelmulde 32 bildet.According to the invention, the collar transfer takes place by coordinated adjustment of the axes of
Dieser Vorgang des sukzessiven Anstellens benachbarter Tragrollen ist im Folgenden anhand einer zeitlichen Abfolge näher erläutert:
Ausgegangen wird dabei von einer Lage des Metallbundes 4, in welcher dieser auf zwei Tragrollen 11 und 12 aufliegt (
It is assumed that a position of the
Um den Metallbund 4 aus dieser stabilen Lage heraus in Richtung der Abwickelposition 6 zu bewegen, wird der Tragrahmen 7 gekippt und gleichzeitig gesenkt. Wie aus der
Für den weiteren Transfer wird nun die erste Tragrolle 13 in Richtung des Pfeils 19 um die Achse 27 nach unten geschwenkt, wodurch aufgrund der Schwerkraft wieder die Seitwärtsbewegung des Metallbundes 4 in
Ein weiteres Absenken der ersten Tragrolle 13 veranlasst den Metallbund 4 seine Seitwärtsbewegung in Richtung zur Abwickelposition 6 erneut fortzusetzen. Unterstützt wird dies durch eine im Uhrzeigersinn gerichtete Schwenkbewegung des Tragrahmens 7, wobei der erste Rahmenteil 29 um die Achse 25 in Richtung des Pfeils 21 verdreht wird. Die Abwickelmulde 32 hat sich also samt dem auf ihr abrollenden Metallbund 4 in Richtung des Pfeils 8 weiter bewegt. Nun stützen wieder drei Tragrollen den Metallbund 4 (
Die
Um den Metallbund 4 aus dieser Position heraus und weiter in Richtung der Abwickelposition 6 zu bewegen, wird das "Wellental" weiter nach links verschoben. Wie in
Schlussendlich werden im letzten Schritt die erste Tragrolle 13 und die zweite Tragrolle 14 entgegen dem Uhrzeigersinn nach oben geschwenkt, wodurch der Metallbund 4 angehoben wird. Sobald sich die zweite Tragrolle 14 auf Höhe der gestellfesten dritten Tragrolle 15 befindet, ist der Transfer des Metallbundes 4 abgeschlossen. Der Metallbund 4 befindet sich nun in der Abwickelposition 6. Eine Rolle 10 fungiert bei diesem letzten Bewegungsabschnitt als Rückhalterolle oder Stützrolle und verhindert, dass der Metallbund 4 aufgrund der starren Anordnung der Tragrolle 15 zu weit in Richtung des Treibers rollt. Um diesen letzten Transferschritt möglichst sanft abzufangen, ist die Stütz- oder Rückhalterolle 10 längs des Doppelpfeils 9 in horizontaler Richtung lageveränderbar. Mittels der angestellten Rolle 10, die am Umfang des Bundes 4 abrollt, wird erreicht, dass der sich abwickelnde Bund gegen Bandende hin mit Dorne versehen werden kann, um ein Zusammendrücken der letzten Windungen zu verhindern. Die horizontale Verschiebbarkeit der Rolle 10 erlaubt ein Positionieren des Bundauges 20 vor dem Einfahren eines Dorns.Finally, in the last step, the
Das Prinzip der Bewegung einer fortschreitenden Bodensenke hat den Vorteil, dass sich der Metallbund fortwährend in einer Mulde, das heißt in einer stabilen Lage befindet. Die Weitergabe des Metallbundes 4 von Tragrolle zu Tragrolle kann durch entsprechende Anstellung der Tragrollen vergleichsweise sanft erfolgen.The principle of moving a progressive floor sink has the advantage that the metal collar is constantly in a trough, that is in a stable position. The transfer of the
Wie bereits erwähnt, ist jede der Rollen 11, 12, 13, 14 drehangetrieben. Die Umfangsgeschwindigkeit wird dabei so vorgegeben, dass zwischen der Geschwindigkeit des Bandes 2 und der Drehbewegung der Rolle kein Schlupf entsteht. Um diesem Ziel möglichst nahe zu kommen, wird bei der Vorgabe der Drehzahl der Rolle auch der aus der Schwenkbewegung der Rolle sich ergebende lineare Geschwindigkeitsanteil berücksichtigt.As already mentioned, each of the
