Description

Greifer für Restbunde, die am Walzende aus Bandanlagen laufendem Restband wickelbar sindGrippers for remaining bundles that can be wound at the end of the roll from the remaining strip
Die Erfindung betrifft einen Greifer für Restbunde, die am Walzende aus aus Bandanlagen laufendem Restband wickelbar sind, wobei der Greifer über einer Bandanlage schwenkbar oder verfahrbar angeordnet ist.The invention relates to a gripper for residual bundles which can be wound at the end of the roll from residual strip running from belt systems, the gripper being arranged pivotably or displaceably over a belt system.
Bei Nachwalzwerken, insbesondere bei Fein- und Weißbandwalzungen, werden Restbunde mit einer Austragvorrichtung vom Abwickel-Haspeldom übernommen und einer Schrottverwertung zugeführt.In the case of re-rolling mills, in particular in the case of fine and white strip rolling, residual bundles are taken from the unwinding reel dome with a discharge device and sent to a scrap recycling facility.
Der hierzu verwendete Greifer ist als Austragvorrichtung bekannt (DE 87 1 1 281.7 U1). Der Greifer ist über der Anlage schwenkbar oder verfahrbar ange- ordnet. Die Endpositionen sind hierbei der Abwickel-Haspeldom sowie der Schrott-Container oder eine Restbund-Anlage. Das Restband wird in einem Abwickelhaspel zum Restbund aufgewickelt, wonach der Greifer den Restbund ergreift, dann der Haspeldorn entspreizt wird, dann der Haspeldorn aus dem Restbund verfahren wird, der Restbund angehoben und der weiteren Verwer- tung zugeführt wird. Zu diesen Arbeitsgängen ist eine den Ablauf und die Wirtschaftlichkeit des Verfahrens bestimmende Zeit erforderlich, die bislang nicht gesenkt werden konnte. Da jede Zeitersparnis die Wirtschaftlichkeit der Gesamtanlage beeinflusst, ist der Zeit-Faktor von erheblicher Bedeutung.The gripper used for this is known as a discharge device (DE 87 1 1 281.7 U1). The gripper can be swiveled or moved over the system. The end positions are the decoiler and the scrap container or a residual bundle system. The remaining strip is wound up in a decoiler into the remaining bundle, after which the gripper grips the remaining bundle, then the decoiler mandrel is despread, then the coiler mandrel is moved out of the remaining bundle, the remaining bundle is raised and used for further use. These steps require a time that determines the sequence and the economic viability of the process, which could not be reduced so far. Since every time saved influences the economic efficiency of the overall system, the time factor is of considerable importance.
Der Erfindung liegt die Aufgabe zugrunde, durch die Ausbildung des Greifers eine rationellere Arbeitsweise zu ermöglichen.The invention has for its object to enable a more rational operation by training the gripper.
Die gestellte Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Greifer neben seiner Funktion als Austragvorrichtung zusätzlich als Wickelvorrichtung ausgebildet ist. Dadurch kann ein bisheriger Schritt, nämlich das getrennte Wik- keln des Restbandes zu einem Restbund auf einem Haspeldorn eliminiert werden, wodurch sich eine erhebliche Zeitersparnis ergibt. Aus diesem Grund ar- beitet die Gesamtanlage wirtschaftlicher. So kann bei jedem Coil eine Zeit von 20 Sekunden eingespart werden, wodurch bei 5 Coils / h in einem 3-Schicht- Betrieb ca. 140 h / Jahr eingespart werden können. Anders betrachtet können aufgrund der Erfindung 140 Stunden an zusätzlicher Produktionszeit gewonnen werden.The object is achieved according to the invention in that the gripper, in addition to its function as a discharge device, is also designed as a winding device. In this way, a previous step, namely the separate winding of the remaining strip into a residual bundle on a coiler mandrel, can be eliminated, which results in considerable time savings. For this reason, works the entire system more economically. A time of 20 seconds can be saved for each coil, which means that at 5 coils / h in a 3-shift operation, approx. 140 h / year can be saved. In other words, 140 hours of additional production time can be gained due to the invention.
Die Erfindung kann konstruktiv aufgrund verschiedener Gestaltungen verwirklicht werden. Eine vorteilhafte Ausgestaltung besteht darin, dass an der um eine parallel zur Haspeldornachse verlaufenden Schwenkachse ein Paar Greifarme gegeneinander schwenkbar gelagert sind, und an deren Endbereichen jeweils innen liegend eine Tragrolle und an einem Greifarm-Ende eine angetriebene Rolle und am gegenüberliegenden, anderen Greifarm-Ende eine Gegenrolle drehbar gelagert sind. Dadurch wird der Greifer nicht nur zur Austragvorrichtung sondern zusätzlich zur Wickelvorrichtung. Das Aufwickeln des Restbandes erfolgt daher nicht mehr auf dem Haspeldorn, sondern unmittelbar im Greifer. Diese Verlagerung des Aufwickelvorgangs in den Greifer bewirkt die genannte Zeitersparnis. Hierdurch kann z.B. ein Doppelspreizkopf-Abwickelhaspel früher geöffnet werden, der Restbund (auch wenn dieser noch zurückgewickelt wird) früher angehoben und somit das nächste Coil der Anlage früher zugeführt werden. Die Bundfolgezeit kann sich hierbei erheblich verkürzen, was zu der wirt- schaftlicheren Nutzung der Gesamtanlage führt. Außerdem wird sichergestellt, dass der Restbund aufgewickelt werden kann und gleichzeitig der Haspeldorn entspreizt und vertikal verfahren werden kann. Die angetriebene Rolle fördert das Restband in die zangenförmige Tragvorrichtung und treibt gleichzeitig den Restbund an. Unmittelbar nachdem die Haspeldorne aus dem Restbund verfah- ren sind, wird der Greifer mit dem Restbund angehoben und das nächste Coil kann auf Haspeldornmitte einfahren.The invention can be implemented constructively on the basis of various designs. An advantageous embodiment consists in that a pair of gripper arms are pivotally mounted against one another on the swivel axis running parallel to the coiler mandrel axis, and on the end regions there is a support roller on the inside and a driven roller on one end of the gripper arm and on the opposite, other end of the gripper arm a counter roller are rotatably mounted. As a result, the gripper not only becomes a discharge device but also a winding device. The remaining strip is therefore no longer wound on the reel mandrel, but directly in the gripper. This shifting of the winding process into the gripper brings about the time saving mentioned. This can e.g. a double expansion head decoiler can be opened earlier, the remaining bundle (even if it is still being rewound) raised earlier and thus the next coil can be fed to the system earlier. The subsequent covenant time can be shortened considerably, which leads to more economical use of the entire system. It also ensures that the remaining bundle can be wound up and at the same time the decoiler can be despread and moved vertically. The driven roller conveys the remaining strip into the pincer-shaped carrying device and at the same time drives the remaining strip. Immediately after the reel mandrels have moved out of the remaining bundle, the gripper with the remaining bundle is raised and the next coil can move into the middle of the reel mandrel.
Für den Klemmvorgang des Greifers genügt es, dass die Tragrollen leerlaufend drehgelagert sind. Eine weitere Ausgestaltung sieht vor, dass die Gegenrolle mit kleineremFor the gripping process of the gripper, it is sufficient that the idler rollers are idly pivoted. Another embodiment provides that the counter roller with a smaller one
Durchmesser als die zugeordnete angetriebene Rolle ausgebildet ist. Dadurch wird die Antriebskraft zum Transportieren, Führen und Biegen des Restbandes aufgebracht, wobei die Gegenrolle lediglich Biegearbeit übernimmt.Diameter is designed as the associated driven roller. As a result, the driving force for transporting, guiding and bending the remaining strip is applied, the counter roller merely taking over bending work.
Die anzustrebende Konstellation für die Gegenrolle und die angetriebene Rolle wird dadurch unterstützt, dass das Schwenkgelenk für die schwenkbaren Greifarme in Betriebsstellung eine Ebene mit der Haspeldornachse bildet.The desired constellation for the counter roller and the driven roller is supported in that the swivel joint for the swiveling gripper arms forms a plane with the reel mandrel axis in the operating position.
Diese Konstellation wird weiter dadurch unterstützt, dass die angetriebene Rolle um einen Winkelbetrag von 5° bis 10° vor der Ebene, in der die Haspeldornachse und die Schwenkachse des Greifarm-Paars in Betriebsstellung verlaufen, angeordnet ist.This constellation is further supported by the fact that the driven roller is arranged at an angle of 5 ° to 10 ° in front of the plane in which the coiler mandrel axis and the pivot axis of the gripper arm pair run in the operating position.
Die Konstellation wird weiter dahingehend ausgenutzt, dass die Gegenrolle mit ihrer Drehachse zur angetriebenen Rolle mit einem Abstand zum momentanen Umfang des aufzuwickelnden Restbandes angeordnet ist. Der Vorteil ist dabei, dass das Anwachsen des Restbundes automatisch durch die Verstellung der Greifarme nach außen berücksichtigt werden kann.The constellation is further used to the effect that the counter-roller is arranged with its axis of rotation to the driven roller at a distance from the current circumference of the remaining tape to be wound up. The advantage here is that the growth of the remaining bundle can be automatically taken into account by adjusting the gripping arms to the outside.
Um diesen Abstand einzustellen und einzuhalten ist außerdem vorgesehen, dass dieIn order to set and maintain this distance, it is also provided that the
Tragrollen mit ihrer Drehachse etwa jeweils am inneren Umfang eines Greifarms drehgelagert sind.Carrying rollers with their axis of rotation are each rotatably supported on the inner circumference of a gripper arm.
Demgegenüber ist weiter vorgesehen, dass die Gegenrolle und die angetriebene Rolle mit ihren Drehachsen jeweils etwa in der Mitte der Greifarm-Dicke drehgelagert sind.In contrast, it is further provided that the counter roller and the driven roller with their axes of rotation are each rotatably supported approximately in the middle of the gripper arm thickness.
Diese Bauweise wird noch dadurch ergänzt, dass die Gegenrolle und die ange- triebene Rolle mit ihren Drehachsen jeweils am Ende des jeweiligen Greifarms in einem Enden-Zentrum drehgelagert sind. In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt, das nachstehend näher erläutert wird.This design is supplemented by the fact that the counter roller and the driven roller with their axes of rotation are each pivoted at the end of the respective gripper arm in an end center. In the drawing, an embodiment of the invention is shown, which is explained in more detail below.
Die einzige Figur der Zeichnung zeigt eine Seitenansicht des Greifers mit Restbund.The only figure in the drawing shows a side view of the gripper with a residual collar.
Ein Restbund 1 soll aus einem Restband 2 gewickelt werden. Hierzu wird ein Greifer 3 eingesetzt, um am Walzende aus aus einer Bandanlage laufendem Restband 2 den Restbund 1 zu wickeln, wobei der Greifer 3 über einer Bandanlage schwenkbar oder verfahrbar ist.A remaining bundle 1 is to be wound from a remaining band 2. For this purpose, a gripper 3 is used to wind the remaining bundle 1 from the remaining strip 2 running from a strip system at the end of the roll, the gripper 3 being pivotable or movable over a strip system.
Der Greifer 3 ist einmal in Betriebsstellung 13 und mit seinen Greifarmen 6, 7 aufgeschwenkt außer Betriebsstellung 13a gezeichnet.The gripper 3 is drawn once in the operating position 13 and with its gripping arms 6, 7 pivoted out of the operating position 13a.
Hierfür weist der Greifer 3 neben seiner Funktion als Austragvorrichtung 3a zu- sätzlich die Funktion einer Wickelvorrichtung 3b auf. Der Greifer 3 besitzt um eine parallel zur Haspeldornachse 4 parallel verlaufende Schwenkachse 5 gegenläufig schwenkbare Greifarme 6 und 7. An den Endbereichen 6a und 7a der Greifarme 6 und 7 sind jeweils innen liegend eine Tragrolle 8 und an einem Greifarm- Ende 7b eine angetriebene Rolle 9 und am gegenüberliegenden, anderen Greifarm-Ende 6b eine Gegenrolle 10 drehbar gelagert. Die Tragrollen 8 sind leerlaufend drehgelagert und halten den Restbund 1 horizontal und vertikal.For this purpose, the gripper 3, in addition to its function as a discharge device 3a, also has the function of a winding device 3b. The gripper 3 has gripping arms 6 and 7 which can be pivoted in opposite directions about a swivel axis 5 which runs parallel to the reel mandrel axis 4. At the end regions 6a and 7a of the gripping arms 6 and 7 there is a support roller 8 on the inside and a driven roller 9 at a gripping arm end 7b and a counter roller 10 is rotatably mounted on the opposite, other gripper arm end 6b. The idler rollers 8 are idly rotatably mounted and hold the remaining bundle 1 horizontally and vertically.
Die Gegenrolle 10 ist mit kleinerem Durchmesser als die zugeordnete angetrie- bene Rolle 9 versehen. Die Anordnung der Tragrollen 8, der angetriebenen Rolle 9 und der Gegenrolle 10 ist derart getroffen, dass ein Schwenkgelenk 1 1 für die schwenkbaren Greifarme in Betriebsstellung eine Ebene 12 mit der Haspeldornachse 4 bildet. Die angetriebene Rolle 9 ist um einen Winkelbetrag von 5° bis 10° vor der Ebene 12, die die Haspeldornachse 4 und die Schwenkachse 5 des Greifarm-Paares 6, 7 in Betriebsstellung 13 bilden, angeordnet. Die notwendige Freiheit des Restbandes 2 für die anwachsende Dicke desThe counter roller 10 is provided with a smaller diameter than the assigned driven roller 9. The arrangement of the support rollers 8, the driven roller 9 and the counter roller 10 is such that a swivel joint 11 for the pivotable gripper arms in the operating position forms a plane 12 with the reel mandrel axis 4. The driven roller 9 is arranged at an angular amount of 5 ° to 10 ° in front of the plane 12, which form the coiler mandrel axis 4 and the pivot axis 5 of the gripper arm pair 6, 7 in the operating position 13. The necessary freedom of the remaining tape 2 for the increasing thickness of the
Restbundes 1 ergibt sich dadurch, indem die Gegenrolle 10 mit ihrer Drehachse 10a zur angetriebenen Rolle 9 mit einem Abstand 14 zum momentanen Umfang 15 des aufzuwickelnden Restbandes 2 angeordnet ist. Der Abstand 14 wird noch dadurch eingehalten, dass die Tragrollen 8 mit ihrer Drehachse 8a etwa jeweils am inneren Umfang 6c, 7c eines Greifarms 6 und 7 drehgelagert sind.The rest of the bundle 1 results from the counter roll 10 being arranged with its axis of rotation 10a to the driven roll 9 at a distance 14 from the current circumference 15 of the remaining strip 2 to be wound up. The distance 14 is also maintained by the fact that the support rollers 8 with their axes of rotation 8a are each rotatably supported on the inner circumference 6c, 7c of a gripper arm 6 and 7.
Die Gegenrolle 10 und die angetriebene Rolle 9 sind mit ihren Drehachsen 10a, 9a jeweils etwa in der Mitte der Greifarm-Dicke 16 drehgelagert.The counter roller 10 and the driven roller 9 are each rotatably supported with their axes of rotation 10a, 9a approximately in the middle of the gripper arm thickness 16.
Die Konstellation wird noch dadurch ergänzt, dass die Gegenrolle 10 und die angetrieben Rolle 9 mit ihren Drehachsen 10a, 9a jeweils am Ende 6b, 7b des jeweiligen Greifarms 6 oder 7 in einem Enden-Zentrum 17 drehgelagert sind. The constellation is supplemented by the fact that the counter roller 10 and the driven roller 9 with their axes of rotation 10a, 9a are each rotatably supported at one end center 17 at the end 6b, 7b of the respective gripper arm 6 or 7.
