Abstract

The aim of the invention is to configure a device for winding and unwinding partly rolled products, in a way that ensures the smallest possible accumulation of scrap. To achieve this, a roller ( 20, 20', 20 '') whose position is controlled and which runs on the periphery of the coil is used during the transfer of the coils from the winding station to the unwinding station. The vertical adjustment of said roller ensures that the coil is completely unwound, even with a diminishing coil diameter.

Description

Vorrichtung zum Auf- und Abwickeln von warmgewalzten Vorbändern aus heißem MetallDevice for winding and unwinding hot-rolled pre-strips made of hot metal
Die Erfindung betrifft eine Vorrichtung zum wahlweisen Aufrollen von Zwischenwalzgut, Abrollen und Versetzen der gebildeten Coils oder zum unaufgerollten Durchlaufenlassen des Zwischenwalzgutes mit einer Biegewalzeneinrichtung, die dem sie durchlaufenden Walzgut eine Abwärtsbiegung erteilt und einem Rollgang dessen treibenden Rollen den Wickelvorgang unterstützen und Abwickelvorgänge sowie eine Weiterführung gebildeter Coils bewirken, um die Wickelposition freizugeben und mit einem durchlaufendes oder abgewickeltes Zwischenwalzgut fördernden Treiber.The invention relates to a device for selectively rolling up intermediate rolling stock, unrolling and moving the formed coils or for unrolling the intermediate rolling stock with a bending roller device which gives the rolling stock through it a downward bend and a roller table whose driving rollers support the winding process and unwinding processes and a further development Coils to release the winding position and with a continuous or unwound intermediate rolling driver.
Durch die DE-OS 25 19 988 ist eine Vorrichtung zum Auf- und Abwickeln von warmgewalzten Vorbändern aus heißem Metall bekanntgeworden, mittels derer warmgewalztes Vorband in einer Position domlos aufgewickelt werden und bei der mittels eines in das Wickelauge des Coils eingreifenden Arms das gewickelteFrom DE-OS 25 19 988 a device for winding and unwinding hot-rolled pre-strips made of hot metal has become known, by means of which hot-rolled pre-strips are wound domless in a position and in which the wound by means of an arm engaging in the winding eye of the coil
Coil aus der Aufwickelposition in eine Abwickelposition gehoben werden kann.Coil can be lifted from the winding position into an unwinding position.
Bereits vor der Überführung und während des Überführens wird das Vorband vom Coil abgewickelt, so daß zumindest die Bereiche des Vorbandes, die imEven before the transfer and during the transfer, the preliminary strip is unwound from the coil, so that at least the areas of the preliminary strip which are in the
Wickelauge liegen, auf dem Arm abrollen und dort beschädigt werden können, wodurch ein großer Schrottanfall entsteht.Wrapping eyes lie on, roll on the arm and can be damaged there, resulting in a large amount of scrap.
Es wurde auch schon vorgeschlagen, die gewickelten Coils aus der Aufwickelposition mittels an den Außenumfang des Coils anlegbare und über Hebel verschwenkbare Rollen über den Rollgang in die Abwickelposition zu verschieben bzw. zu rollen. Diese Versetz- Bewegung ist jedoch unkontrolliert, so daß das Coil gegen in der Abwickelposition angeordnete Anschläge rollt, wobei es zur Beschädigung der äußeren Windung des Coils kommen kann, bevor das Coil in seine vorgegebene Abrollposition zurückfällt. Beim Abrollen kann das kleiner werdende Coil durch die Kraft des abziehenden Treibers aus der Abwickelposition herausgezogen werden. Dabei wird der Rest des Coils unter den Anschlag in den Treiber gezogen, wo dann eventuell mehrere Windungen des Coils gemeinsam den Treiber passieren oder aber es zum Stau und zur Abschaltung der Anlage kommt. Auch hier fallen erhebliche Mengen von Schrott an.It has also been proposed to move or roll the wound coils out of the winding position by means of rollers which can be placed on the outer circumference of the coil and pivoted by means of levers over the roller table into the unwinding position. However, this displacement movement is uncontrolled, so that the coil rolls against stops arranged in the unwinding position, which can damage the outer winding of the coil before the coil falls back into its predetermined unwinding position. When unrolling, the shrinking coil can be pulled out of the unwinding position by the force of the pulling driver. The rest of the coil is pulled under the stop into the driver, where several turns of the coil may pass the driver together or the system may jam and shut down. Significant amounts of scrap are also generated here.
Es wurden auch schon Coil-Überführungsvorrichtungen vorgeschlagen, bei denen durch entsprechendes Kippen bzw. Anheben der Rollgangsrollen die Coils aus der Aufwickelposition in die Abwickelposition verbracht werden. Die Probleme beim Abziehen des Coils, insbesondere wenn dieses kleiner wird, konnten auch hier nicht gelöst werden.Coil transfer devices have also been proposed in which the coils are moved from the winding position into the unwinding position by appropriately tilting or lifting the roller table rollers. The problems with pulling off the coil, especially when it becomes smaller, could not be solved here either.
Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Vorrichtung so weiterzubilden, daß ein kostengünstiges Betreiben dieser Vorrichtung gewährleistet ist und daß beim Betreiben möglichst kein Schrott anfällt.The invention has for its object to develop a generic device so that an inexpensive operation of this device is guaranteed and that no scrap is generated when operating.
Diese Aufgabe wird dadurch gelöst, daß mindestens eine Rolle vorgesehen ist, die am Umfang des in die Abwickelposition zu überführende bzw. überführten Coils abläuft und das Coil in der Abwickelposition hält. Die Rolle gewährleistet dabei, daß das Coil sicher in die Abwickelposition überführt wird, ohne über diese hinaus gegen Anschläge zu rollen, und daß das Coil während seiner kompletten Abwickelphase sicher in der Abwickelposition verbleibt, so daß das Restcoil nicht in den nachgeschalteten Treiber gelangen kann.This object is achieved in that at least one roller is provided which runs on the circumference of the coil to be transferred or transferred into the unwinding position and holds the coil in the unwinding position. The roller ensures that the coil is safely transferred to the unwinding position without rolling against stops, and that the coil remains securely in the unwinding position during its complete unwinding phase, so that the rest of the coil cannot get into the downstream driver.
Werden die Rollen des Rollgangs und die den Umfang des Coils abstützenden Rollen in Zwischenwalzgut- Laufrichtung kraftbetrieben gleichzeitig versetzbar ausgeführt, so kann die am Umfang des Coils ablaufende Rolle das Coil während der Übergabebewegung aus der Aufwickelposition in die Abwickelposition bereits gegen ungewollte Bewegungen in Zwischenwalzgut- Laufrichtung sichern. Werden die tragenden Rollen in einem gemeinsamen Wagen angeordnet und der Wagen in Zwischenwalzgut- Laufrichtung verfahrbar vorgesehen, so ist gewährleistet, daß das Coil während seines Transports nicht über mehrere Rollen eines Rollgangs hinweg verschoben bzw. gerollt werden muß, so daß dadurch erheblich weniger Beschädigungen der äußeren Windungen des Coils hervorgerufen werden können.If the rollers of the roller table and the rollers supporting the circumference of the coil are designed to be displaceable in a power-operated manner in the intermediate rolling direction, the roller running on the circumference of the coil can already move the coil against unwanted movements in the intermediate rolling direction during the transfer movement from the winding position into the unwinding position to back up. If the load-bearing rollers are arranged in a common carriage and the carriage is provided such that it can be moved in the intermediate rolling direction, it is ensured that the coil does not have to be moved or rolled over several rollers of a roller table during its transport, so that considerably less damage is caused to it outer turns of the coil can be caused.
Es hat sich als vorteilhaft erwiesen, wenn die stützenden Rollen zusätzlich über mindestens einen Antrieb vertikal verlagerbar und mit abnehmenden Coildurchmessern absenkbar sind, wobei eine Steuervorrichtung für den Antrieb vorgesehen ist, welche die Stützrollen in Abhängigkeit des Coildurchmessers und/oder der Abwickellänge und/oder der Abwickelzeit vertikal absenkt. Dadurch läßt sich die Abstützposition der stützenden Rollen optimal an den Coildurchmesser anpassen, so daß auch noch kleinste Coildurchmesser sicher abgestützt werden können.It has proven to be advantageous if the supporting rollers can additionally be displaced vertically via at least one drive and can be lowered with decreasing coil diameters, a control device being provided for the drive, which supports the support rollers depending on the coil diameter and / or the unwinding length and / or the Unwinding time reduced vertically. As a result, the support position of the supporting rollers can be optimally adapted to the coil diameter, so that even the smallest coil diameter can be securely supported.
Um den Rest des abzuwickelnden Zwischenwalzgutes noch sicherer davor zu schützen in den Treiber gezogen zu werden hat es sich bewährt, auf das ablaufende Zwischenwalzgut einen Hebel abzusenken, der sich mit einer Laufrolle auf das Zwischenwalzgut und mit einer höher gelagerten Stützrolle gegen den Umfang des Coils legt.In order to protect the rest of the intermediate rolling stock to be pulled even more securely from being pulled into the driver, it has proven useful to lower a lever on the running intermediate rolling stock, which is placed on the intermediate rolling stock with a roller and against the circumference of the coil with a higher supporting roller ,
Eine weitere Möglichkeit sicherzustellen, daß das Zwischenwalzgut vollkommen vom Coil abgewickelt wird, bevor es in den Treiber gelangt, wird erreicht, wenn beidseitig des Rollgangs in der Endposition des Auges eines abzuwickelnden Coils in dieses einfahrbare Dome vorgesehen sind, wobei die Dorne in Abhängigkeit des Coildurchmessers und/oder der Abwickellänge und/oder der Abwickelzeit in das Auge des Restcoils einfahrbar sind und auf den Dornen Rollen angeordnet sind, die gegebenenfalls auf Abwickelgeschwindigkeit angetrieben werden können und die eine Beschädigung des Zwischenwalzguts ausschließen. Die Erfindung wird anhand eines Ausführungsbeispieles näher erläutert. Dabei zeigenA further possibility of ensuring that the intermediate rolling stock is completely unwound from the coil before it reaches the driver is achieved if retractable domes are provided on both sides of the roller table in the end position of the eye of a coil to be unwound, the mandrels depending on the coil diameter and / or the unwinding length and / or the unwinding time are retractable into the eye of the rest of the coil and rollers are arranged on the mandrels, which can optionally be driven to the unwinding speed and which prevent damage to the intermediate rolling stock. The invention is explained in more detail using an exemplary embodiment. Show

Der Fig. 1 ist eine Aufwickelstation 1 und eine Abwickelstation 2 für bandförmiges Zwischenwalzgut 3 entnehmbar. Bei der Aufwickelstation 1 handelt es sich um einen an sich bekannten dornlosen Abwärtswickler, bei dem über Eingangsrollen 4, 4' das in die Aufwickelstation 1 einlaufende Band 3 nach oben abgelenkt wird. Durch die Biegerollen 5, 5', 5" wird dem Band 3 eine Abwärtskrümmung erteilt. Das Band 3 wird in der aus den Rollen 6, 6' und 7, 7' gebildeten Aufwickelkammer 8 zu einem Coil gewickelt.1, a winding station 1 and an unwinding station 2 for strip-shaped intermediate rolling stock 3 can be seen. The winding station 1 is a known thornless downward winder, in which the band 3 entering the winding station 1 is deflected upwards by means of input rollers 4, 4 '. The bending roll 5, 5 ', 5 "gives the strip 3 a downward curvature. The strip 3 is wound into a coil in the winding chamber 8 formed by the rolls 6, 6' and 7, 7 '.
Sowohl die Eingangsrollen 4 als auch die Rolle 7' sind aus der gezeigten, angehobenen Position auf das Niveau der Rolle 6' sowie der Rollgangsrolle 9 absenkbar. In dieser Position bilden die Rollen 4, 9, 6', 7 und 7' einen Rollgang, über den das Band 3 ohne abgelenkt zu werden, durch die Aufwickelstation 1 geführt werden kann.Both the input rollers 4 and the roller 7 'can be lowered from the shown raised position to the level of the roller 6' and the roller table roller 9. In this position, the rollers 4, 9, 6 ', 7 and 7' form a roller table, via which the belt 3 can be guided through the winding station 1 without being deflected.
Der Aufwickelstation 1 ist eine Bandbund-Öffenvorrichtung 10 zugeordnet, welche nach erfolgtem Wickeln des Coils in der Aufwickelkammer 8 und einer Drehrichtungsumkehr der angetriebenen Rollen 7, 7' gegen das Coil geschwenkt werden kann, um mit dem Schälmesser 11 das Coil zu öffnen und den Bandanfang zur Abwickelstation 2 zu leiten. Die Abwickelstation 2 besteht aus einem Wagen 12 und einem Ständer 13, in dem die Treiberrollen 14, 14', 14" des über eine Kolben-Zylinder-Einheit 15 anstellbaren Treibers 16 gelagert sind. Am Ständer 13 greift ein Verschiebezylinder 17 für den Wagen 12 an. Weiterhin ist am Ständer 13 eine in ihrer horizontalen Richtung über eine Kolben-Zylinder-Einheit 18 und in ihrer vertikalen Richtung über eine Kolben-Zylinder-Einheit 19 anstellbare Rolle 20 an einem Winkelhebel 21 angelenkt. Der Ständer 13 weist weiterhin eine Rollgangsrolle 22 auf, über die das Band 3 dem Treiber 16 zugeführt wird.The winding station 1 is assigned a coil opening device 10 which, after the coil has been wound in the winding chamber 8 and the direction of rotation of the driven rollers 7, 7 'can be pivoted against the coil in order to open the coil and the beginning of the strip with the peeling knife 11 to lead to the unwind station 2. The unwinding station 2 consists of a carriage 12 and a stand 13, in which the driver rollers 14, 14 ', 14 "of the driver 16, which can be set by means of a piston-cylinder unit 15, are mounted. A displacement cylinder 17 for the carriage 12 engages on the stand 13 Furthermore, a roller 20 which can be adjusted in its horizontal direction by means of a piston-cylinder unit 18 and in its vertical direction by means of a piston-cylinder unit 19 is articulated on an angle lever 21. The stand 13 also has a roller table roller 22 on the tape 3 is fed to the driver 16.
Auf dem Wagen 12 sind angetriebene Rollen 23, 23' angeordnet, die das Coil 24 im Sinne einer Abrollbewegung anzutreiben vermögen.Driven rollers 23, 23 'are arranged on the carriage 12, which are able to drive the coil 24 in the sense of a rolling movement.
Die Vorrichtung nach Fig. 1 kann im Durchlauf betrieben werden. Dazu müssen die Rollen 4, 7, 7' und 23, 23' auf das Rollgangsniveau abgesenkt sein, so daß sich aus diesen Rollen und den Rollen 6' und 22 ein Rollgang ergibt, über den das Band 3 vom Einlauf der Aufwickelstation 1 direkt zum Treiber 16 gelangen kann.1 can be operated continuously. For this purpose, the rollers 4, 7, 7 'and 23, 23' must be lowered to the roller table level, so that a roller table results from these rollers and the rollers 6 'and 22, via which the belt 3 from the inlet of the winding station 1 directly to Driver 16 can get.
In der Regel wird das Band 3 jedoch von den Eingangsrollen 4, 4' und den Biegerollen 5, 5', 5" in die Aufwickelkammer 8 geleitet, wo es zu einem Coil aufgewickelt wird. Zum Anwickeln des Coils ist die Rolle 7" noch in der dargestellten angehobenen Stellung positioniert. Sobald einige Windungen des Coils gewickelt sind, wird die Rolle 7' auf Rollgangsniveau abgesenkt und das Coil nur noch von den angetriebenen Rollen 7, 7' getragen. In dieser Position wird das Coil fertig gewickelt.As a rule, however, the tape 3 is fed from the input rollers 4, 4 'and the bending rollers 5, 5', 5 "into the winding chamber 8, where it is wound into a coil. The roller 7" is still in for winding the coil the raised position shown. As soon as a few turns of the coil have been wound, the roller 7 'is lowered to the roller table level and the coil is only carried by the driven rollers 7, 7'. In this position, the coil is completely wound.
Das zum Aufwickeln im Uhrzeigersinn angetriebene Coil wird nach seiner Fertigstellung durch Drehrichtungsumkehr der angetriebenen Rollen 7, 7' entgegen dem Uhrzeigersinn angetrieben. Gleichzeitig wird die Bandbund- Öffenvorrichtung 10 gegen das Coil geschwenkt, so daß das ehemalige Bandende nunmehr als Bandanfang vom Coil abgeschält und dem Treiber 16 zugeführt wird. In der Zwischenzeit wurde der Verschiebezylinder 17 ausgefahren, so daß der Wagen 12, auf dem sich kein Coil 24 mehr befindet, bis an die Rolle 7' herangefahren ist. Gleichzeitig wird die Rolle 20 mittels der Kolben-Zylinder- Einheiten 18, 19 in Richtung auf die Aufwickelstation 1 in eine Position gegen bzw. annähernd gegen das dort befindliche Coil verschwenkt.The coil driven for winding in a clockwise direction is driven counterclockwise after its completion by reversing the direction of rotation of the driven rollers 7, 7 '. At the same time, the tape bundle opening device 10 is pivoted against the coil, so that the former tape end is now peeled off from the coil as the beginning of the tape and fed to the driver 16. In the meantime, the displacement cylinder 17 has been extended so that the carriage 12, on which there is no longer a coil 24, reaches the roller 7 '. has approached. At the same time, the roller 20 is pivoted by means of the piston-cylinder units 18, 19 in the direction of the winding station 1 into a position against or approximately against the coil located there.
Sobald der Treiber 16 das Band 3 erfaßt hat, wird durch Anheben der Rolle 7 das Coil aus der Aufwickelstation 1 auf die Rollen 23, 23' des Wagens 12 in die Abwickelstation 2 übergeben. Dabei sorgt die Rolle 20, die beim Übergabevorgang gegebenenfalls entsprechend in Richtung auf den Ständer 13 zurückverschwenkt werden kann, dafür, daß das Coil 24 nicht über die Rolle 23' hinaus rollen kann.As soon as the driver 16 has gripped the tape 3, the coil 7 is transferred from the winding station 1 onto the rollers 23, 23 'of the carriage 12 into the unwinding station 2 by lifting the roll 7. The roller 20, which can optionally be pivoted back in the direction of the stand 13 during the transfer process, ensures that the coil 24 cannot roll beyond the roller 23 '.
Anschließend werden der Wagen 12 und die Rolle 20 in Richtung auf den Ständer 13 verschoben, so daß die Aufwickelstation 1 zum Wickeln eines neuen Coils frei wird. Bei kleiner werdendem Coil 24 in der Abwickelstation 2 kann die Rolle 20 mittels der Kolben-Zylinder-Einheit 19 vertikal so angestellt werden, daß auch noch ein sehr kleines Restcoil sicher von der Rolle 20 abgestützt wird, so daß das Restcoil nicht in den Treiber 16 eingezogen werden kann.Then the carriage 12 and the roller 20 are moved in the direction of the stand 13, so that the winding station 1 is free for winding a new coil. When the coil 24 in the unwinding station 2 becomes smaller, the roller 20 can be adjusted vertically by means of the piston-cylinder unit 19 so that even a very small residual coil is securely supported by the roller 20, so that the residual coil does not enter the driver 16 can be moved.
Fig. 2 zeigt eine der Rolle 20 ähnliche Rolle 20', die jedoch im wesentlichen lediglich horizontal über eine Kolben-Zylinder-Einheit 18' anstellbar ist. Damit das Restcoil 24' nicht in den Treiber 16' eingezogen werden kann, ist ein Hebel 25 vorgesehen, der über eine Kolben-Zylinder-Einheit 26 auf das Band 3' zu verschwenkt werden kann. Der Hebel 25 weist Rollen 27, 28 auf, wobei die Laufrolle 27 gegen die Rollgangsrolle 22' verschwenkbar ist und die Rollgangsrolle 22' und die Laufrolle 27 das Band 3' zwischen sich einschließen. Die Stützrolle 28 ist so an der Spitze des Hebels 25 angeordnet, daß sie sich gegen das Restcoil 24 anlegt, ohne das Band 3' im Treibereinlaufbereich zu berühren.Fig. 2 shows a roller 20 'similar to roller 20, which, however, can only be adjusted essentially horizontally via a piston-cylinder unit 18'. So that the remaining coil 24 'cannot be drawn into the driver 16', a lever 25 is provided which can be pivoted towards the belt 3 'via a piston-cylinder unit 26. The lever 25 has rollers 27, 28, the roller 27 being pivotable relative to the roller table 22 'and the roller roller 22' and the roller 27 enclosing the belt 3 'between them. The support roller 28 is arranged at the tip of the lever 25 so that it rests against the rest of the coil 24 without touching the band 3 'in the driver inlet area.
Fig. 3 zeigt eine weitere Alternative, mittels der sichergestellt wird, daß das Coil 24" vollkommen abgewickelt wird. Auch hier sorgt die im wesentlichen horizontal verschwenkbare Rolle 20" dafür, daß das Coil sicher auf dem Wagen 12" verbleibt. Am Ständer 13" ist seitlich des Rollgangs und des Wagens 12" jeweils ein Dom 29 vorgesehen, auf dem jeweils eine Rolle 30 angeordnet ist. Sobald das Coil 24 durch den Abwickelvorgang so klein geworden ist, daß die Rollen 30 in das sich mit absenkendem Coildurchmesser senkende Wickelauge 31 des Coils 24" eingeschoben werden kann, ohne dabei das Coil 24" zu verletzen, wird von beiden Seiten der Dom 29 in das Wickelauge 31 eingeschoben. Die auf den Dornen 29 angeordneten Rollen 30 sorgen dafür, daß das Coil 24" so lange auf dem Wagen 12" gehalten wird, bis es vollständig abgewickelt ist.3 shows a further alternative, by means of which it is ensured that the coil 24 "is completely unwound. Again, the essentially horizontally pivotable roller 20" ensures that the coil is securely on the carriage 12 ". remains. On the stand 13 ", a dome 29 is provided on each side of the roller table and the carriage 12", on each of which a roller 30 is arranged. As soon as the coil 24 has become so small as a result of the unwinding process that the rollers 30 can be inserted into the winding eye 31 of the coil 24 ", which decreases as the coil diameter decreases, without thereby damaging the coil 24", the dome 29 becomes in from both sides the winding eye 31 inserted. The rollers 30 arranged on the mandrels 29 ensure that the coil 24 "is held on the carriage 12" until it is completely unwound.
Die notwendigen Steuer- und Überwachungsvorrichtungen für das Einschieben der Dome 29, das Antreiben der Rollen 30, die Bewegung der Rollen 20, des Wagens 12 und der Rollen 7, 7' sind in den Fig. 1 bis 3 nicht gezeigt. The necessary control and monitoring devices for inserting the domes 29, driving the rollers 30, moving the rollers 20, the carriage 12 and the rollers 7, 7 'are not shown in FIGS. 1 to 3.
