Definitions
- the invention relates to a device for strip processing with at least one decoiling station, at least one strip processing station and at least one decoiling station.
- the band processing consists of trimming a band
- the band is unwound from a coil in a decoiling station, fed to the trimming station, trimmed by trimming knives in the trimming station and then rewound from a reeling station onto a coil.
- generic devices for strip processing are also used for dividing, cold rolling or the like.
- this strip is usually subjected to a plurality of roll passes. Across most of the width of the strip, the decrease in thickness during rolling leads to an increase in the length of the strip. In the area of the strip edges, however, in addition to the effect of the increase in strip length when rolling, the increase in strip width occurs. Due to the increase in the width of the band at the band edge, less material is available for the increase in the band length at the band edge, which leads to eating in the Rarirl oi no shr nrlo-r won i ⁇ or V11-.V1C- Belt edge tension arises. The strip edge tension described leads to various problems in the further strip processing.
- the tape edge tension which is usually very high, trims undesirable edge extensions due to friction of the cut edges on the trimming knife.
- This undesirable edge extension leads on the one hand to a so-called starburst or star pattern formation on the coiled reel and on the other hand to poor processability during further processing.
- band tears which have their origin, among other things, in the fact that the band edges of the can lid band fed to the further processing have a high band edge tension and thus promote crack formation during stretching.
- a high strip edge tension during the rolling process means that in order to overcome the strip edge tension, a higher rolling energy has to be applied with each roll pass than would be necessary if the strip edge tension were completely removed. If the strip edge tension can be reduced between two roll passes, the roll energy required for the second pass is reduced.
- the present invention is based on the object to provide a device for strip processing, which enables a targeted reduction of the strip edge tension in a strip.
- the previously derived and described object is achieved in that a strip edge stretching station stretching the strip edges of the strip is provided between the uncoiling station and the reeling station.
- the strip edge stretching station according to the invention opens up the possibility of reducing the strip edge tension to the desired extent or even specifically producing a strip edge stretching.
- the targeted reduction of the strip edge tension for example, reduces or even completely eliminates the above-described problems in strip processing known from the prior art.
- the device for strip processing according to the invention is particularly suitable for processing strips made of aluminum materials, since, due to the work hardening properties of aluminum, particularly high strip edge stresses occur when cold-rolling aluminum strips.
- the tape processing can consist, in particular, exclusively in stretching the tape edges of the tape.
- One possibility for constructing a strip edge stretching station according to the invention would be, for example, to subject the strip edges to a separate roll pass, which preferably does not involve any processing of the strip between the strip edges. It is conceivable, for example, to arrange two short rollers in the area of the strip edges, which, for example in cooperation with a deflection roller in the rolling mill, roll the strip edges in a targeted manner, as a result of which the strip edge tensions are reduced.
- the tape edge stretching station has two tape edge stretching units which engage laterally in the tape and a tape edge stretching unit each has at least three tape edge deflection rollers.
- the belt edges are stretched in that they do not run straight between the belt edge deflection rollers in the belt transport direction, but are guided in a loop over the belt edge deflection rollers, which leads to stretching of the belt edges due to the path extension for the belt edges.
- the construction of such a strip edge stretching station is very simple and can be easily integrated into existing devices for strip processing.
- the strip edge deflection rollers can be adjusted against one another essentially perpendicular to the strip plane, makes it possible to enforce the loop via the strip edge deflection rollers adjust, which in turn makes the degree of stretching adjustable.
- band edge deflection rollers are designed in the form of a truncated cone according to a development of the invention, on the one hand the threading of the strip edges between the strip edge deflection rollers is simplified and on the other hand it is ensured that an increasing stretching takes place towards the edge of the strip, whereby the tension gradient in the strip edge is taken into account.
- other thickness profiles for the strip edge deflection rollers are also conceivable, which are each adapted to the desired stretching course.
- the band edge stretching devices are arranged in the band plane, displaceable perpendicular to the direction of the tape running, the immersion depth of the band edge deflection rollers in the band can be adjusted and thus the area of the band edges that are stretched vary.

Description
VORRICHTUNG ZUR BANDBEARBEITUNG DEVICE FOR TAPE PROCESSING
Die Erfindung betrifft eine Vorrichtung zur Bandbearbeitung mit mindestens einer Abhaspelstation, mindestens einer Bandbearbeitungsstation und mindestens einer Aufhaspelstation.The invention relates to a device for strip processing with at least one decoiling station, at least one strip processing station and at least one decoiling station.
Derartige Vorrichtungen sind in einer Vielzahl von Ausgestaltungen bekannt. Besteht beispielsweise die , Bandbearbeitung im Besäumen eines Bandes, so wird das Band von einem Coil in einer Abhaspelstation abgehaspelt, der Besäumstation zugeführt, in der Besäumstation durch Besäummesser besäumt und anschließend von einer Aufhaspelstation auf ein Coil aufgehaspelt. Neben dem Besäumen werden gattungsgemäße Vorrichtungen zur Bandbearbeitung auch zum Teilen, Kaltwalzen oder dergleichen eingesetzt.Such devices are known in a variety of configurations. If, for example, the band processing consists of trimming a band, the band is unwound from a coil in a decoiling station, fed to the trimming station, trimmed by trimming knives in the trimming station and then rewound from a reeling station onto a coil. In addition to trimming, generic devices for strip processing are also used for dividing, cold rolling or the like.
Während der Herstellung eines Bandes wird dieses Band in der Regel einer Mehrzahl von Walzstichen unterzogen. Über den größten Teil der Breite des Bandes führt die Dickenabnahme beim Walzen zu einer Längenzunahme des Bandes. Im Bereich der Bandkanten jedoch tritt neben den Effekt der Bandlängenzunahme beim Walzen der der Bandbreitenzunahme. Durch die Zunahme der Breite des Bandes an der Bandkante steht weniger Material für die Zunahme der Bandlänge an der Bandkante zur Verfügung, was azu führt , aß i m Rarirl o-i no shr nrlo-r won i πor V11-.V1C-
Bandkantenspannung entsteht. Die beschriebene Bandkantenspannung führt zu verschiedenen Problemen in der weiteren Bandbearbeitung. So kommt es beispielsweise bei der Herstellung von Dosenbodyband, welches in weiteren Verarbeitungsschritten zum Getränkedosenkörper verarbeitet wird, durch die bei diesem Band meist sehr hohe Bandkantenspannung beim Besäumen zu einer unerwünschten Kantenverlängerung durch Reibung der Schnittkanten am Besäummesser. Diese unerwünschte Kantenverlängerung führt einerseits zu einer sogenannten Starburst- oder Sternmusterbildung am aufgehaspelten Coil und andererseits zu einer schlechten Verarbeitbarkeit bei der Weiterverarbeitung.During the production of a strip, this strip is usually subjected to a plurality of roll passes. Across most of the width of the strip, the decrease in thickness during rolling leads to an increase in the length of the strip. In the area of the strip edges, however, in addition to the effect of the increase in strip length when rolling, the increase in strip width occurs. Due to the increase in the width of the band at the band edge, less material is available for the increase in the band length at the band edge, which leads to eating in the Rarirl oi no shr nrlo-r won i πor V11-.V1C- Belt edge tension arises. The strip edge tension described leads to various problems in the further strip processing. For example, in the manufacture of canned body tape, which is processed into beverage can bodies in further processing steps, the tape edge tension, which is usually very high, trims undesirable edge extensions due to friction of the cut edges on the trimming knife. This undesirable edge extension leads on the one hand to a so-called starburst or star pattern formation on the coiled reel and on the other hand to poor processability during further processing.
Bei der Weiterverarbeitung von sogenanntem Dosendeckelband kommt es bei dem bei der Weiterverarbeitung vorgenommenen Recken gelegentlich zu Bandrissen, die ihren Ursprung unter anderem darin haben, daß die Bandkanten des der Weiterverarbeitung zugeführten Dosendeckelbandes eine hohe Bandkantenspannung aufweisen und damit beim Recken eine Rissbildung begünstigen.In the further processing of so-called can lid band, the stretching carried out during further processing occasionally results in band tears, which have their origin, among other things, in the fact that the band edges of the can lid band fed to the further processing have a high band edge tension and thus promote crack formation during stretching.
Schließlich führt eine hohe Bandkantenspannung während des Walzprozesses dazu, daß zur Überwindung der Bandkantenspannung bei jedem Walzstich eine höhere Walzenergie aufgebracht werden muß, als dies notwendig wäre, wenn die Bandkantenspannung vollständig abgebaut wäre. Kann die Bandkantenspannung also zwischen zwei Walzstichen abgebaut werden, so reduziert sich die erforderliche Walzenergie beim zweiten Stich.Finally, a high strip edge tension during the rolling process means that in order to overcome the strip edge tension, a higher rolling energy has to be applied with each roll pass than would be necessary if the strip edge tension were completely removed. If the strip edge tension can be reduced between two roll passes, the roll energy required for the second pass is reduced.
Ausgehend von dem zuvor beschriebenen Stand der Technik liegt der vorliegenden Erfindung die Aufgabe zugrunde,
eine Vorrichtung zur Bandbearbeitung zu • Verfügung zu stellen, die einen gezielten Abbau der Bandkantenspannung in einem Band ermöglicht.Starting from the prior art described above, the present invention is based on the object to provide a device for strip processing, which enables a targeted reduction of the strip edge tension in a strip.
Erfindungsgemäß ist die zuvor hergeleitete und aufgezeigte Aufgabe dadurch gelöst, daß zwischen der Abhaspelstation und der Aufhaspelstation eine die Bandkanten des Bandes reckende Bandkantenreckstation vorgesehen ist. Durch die erfindungsgemäße Bandkantenreckstation wird die Möglichkeit eröffnet, die Bandkantenspannung im gewünschten Umfang abzubauen oder sogar gezielt eine Bandkantenüberdehnung herzustellen. Durch den gezielten Abbau der Bandkantenspannung werden beispielsweise die oben beschriebenen, aus dem Stand der Technik bekannten Probleme bei der Bandbearbeitung reduziert oder gar vollständig eliminiert.According to the invention, the previously derived and described object is achieved in that a strip edge stretching station stretching the strip edges of the strip is provided between the uncoiling station and the reeling station. The strip edge stretching station according to the invention opens up the possibility of reducing the strip edge tension to the desired extent or even specifically producing a strip edge stretching. The targeted reduction of the strip edge tension, for example, reduces or even completely eliminates the above-described problems in strip processing known from the prior art.
Die erfindungsgemäße Vorrichtung zur Bandbearbeitung eignet sich insbesondere zur Bearbeitung von Bändern aus Aluminiumwerkstoffen, da aufgrund der Kaltverfestigungseigenschaften von Aluminium beim Kaltwalzen von Aluminiumbändern besonders hohe Bandkantenspannungen auftreten.The device for strip processing according to the invention is particularly suitable for processing strips made of aluminum materials, since, due to the work hardening properties of aluminum, particularly high strip edge stresses occur when cold-rolling aluminum strips.
Bei einer erfindungsgemäßen Vorrichtung zur Bandbearbeitung kann die Bandbearbeitung insbesondere ausschließlich im Recken der Bandkanten des Bandes bestehen. Es ist jedoch in der Regel vorteilhaft, das Recken der Bandkanten des Bandes mit mindestens einem weiteren Bearbeitungsschritt, beispielsweise dem Besäumen des Bandes, in einer Vorrichtung zur Bandbearbeitung zur verbinden.
Eine Möglichkeit zur Konstruktion einer erfindungsgemäßen Bandkantenreckstation bestünde beispielsweise darin, die Bandkanten einem separaten Walzstich zu unterziehen, der vorzugsweise keine Bearbeitung des Bandes zwischen den Bandkanten umfaßt. Denkbar ist etwa die Anordnung zweier kurzer Walzen im Bereich der Bandkanten, die beispielsweise im Zusammenwirken mit einer Umlenkrolle im Walzwerk die Bandkanten gezielt walzen, wodurch die Bandkantenspannungen abgebaut werden.In a device for tape processing according to the invention, the tape processing can consist, in particular, exclusively in stretching the tape edges of the tape. However, it is generally advantageous to combine the stretching of the band edges of the band with at least one further processing step, for example trimming the band, in a device for band processing. One possibility for constructing a strip edge stretching station according to the invention would be, for example, to subject the strip edges to a separate roll pass, which preferably does not involve any processing of the strip between the strip edges. It is conceivable, for example, to arrange two short rollers in the area of the strip edges, which, for example in cooperation with a deflection roller in the rolling mill, roll the strip edges in a targeted manner, as a result of which the strip edge tensions are reduced.
In der praktischen Erprobung hat sich als besonders vorteilhaft eine Ausgestaltung der erfindungsgemäßen Vorrichtung zur Bandbearbeitung bewährt, bei der die Bandkantenreckstation zwei seitlich in das Band eingreifende Bandkantenreckeinheiten aufweist und eine Bandkantenreckeinheit die jeweils mindestens drei Bandkantenumlenkrollen aufweist. Bei einer derartigen Bandkantenreckstation werden die Bandkanten dadurch gereckt, daß sie zwischen den Bandkantenumlenkrollen nicht gerade in Bandtransportrichtung hindurchlaufen, sondern über die Bandkantenumlenkrollen in einer Schleife geführt werden, die aufgrund der Wegverlängerung für die Bandkanten zu einem Recken der Bandkanten führt . Eine derartige Bandkantenreckstation ist in ihrem Aufbau sehr einfach und läßt sich problemlos in bestehende Vorrichtungen zur Bandbearbeitung integrieren.In practical testing, an embodiment of the device for tape processing according to the invention has proven to be particularly advantageous, in which the tape edge stretching station has two tape edge stretching units which engage laterally in the tape and a tape edge stretching unit each has at least three tape edge deflection rollers. In such a belt edge stretching station, the belt edges are stretched in that they do not run straight between the belt edge deflection rollers in the belt transport direction, but are guided in a loop over the belt edge deflection rollers, which leads to stretching of the belt edges due to the path extension for the belt edges. The construction of such a strip edge stretching station is very simple and can be easily integrated into existing devices for strip processing.
Dadurch, daß gemäß einer Ausgestaltung der Erfindung die Bandkantenumlenkrollen im wesentlichen senkrecht zur Bandebene gegeneinander einstellbar sind, läßt sich die über die Bandkantenumlenkrollen erzwungene Schleife
einstellen, wodurch wiederum der Grad des Reckens einstellbar wird.The fact that, according to one embodiment of the invention, the strip edge deflection rollers can be adjusted against one another essentially perpendicular to the strip plane, makes it possible to enforce the loop via the strip edge deflection rollers adjust, which in turn makes the degree of stretching adjustable.
Sind die Bandkantenumlenkrollen gemäß einer Weiterbildung der Erfindung kegelstumpfförmig ausgebildet, so vereinfacht sich zum einen das Einfädeln der Bandkanten zwischen die Bandkantenumlenkrollen und zum anderen ist gewährleistet, daß zum Rand des Bandes hin eine zunehmende Reckung erfolgt, wodurch dem Spannungsgradienten in der Bandkante Rechnung getragen wird. Es sind selbstverständlich auch andere Dickenprofile für die Bandkantenumlenkrollen denkbar, die jeweils an den gewünschten Reckverlauf angepaßt sind.If the band edge deflection rollers are designed in the form of a truncated cone according to a development of the invention, on the one hand the threading of the strip edges between the strip edge deflection rollers is simplified and on the other hand it is ensured that an increasing stretching takes place towards the edge of the strip, whereby the tension gradient in the strip edge is taken into account. Of course, other thickness profiles for the strip edge deflection rollers are also conceivable, which are each adapted to the desired stretching course.
Dadurch, daß die Bandkantenreckeinrichtungen in der Bandebene, senkrecht zur Bandlaufrichtung verschiebbar angeordnet sind, läßt sich die Eintauchtiefe der Bandkantenumlenkrollen in das Band einstellen und somit der Bereich der Bandkanten der gereckt wird variieren.Characterized in that the band edge stretching devices are arranged in the band plane, displaceable perpendicular to the direction of the tape running, the immersion depth of the band edge deflection rollers in the band can be adjusted and thus the area of the band edges that are stretched vary.
Es gibt nun eine Vielzahl von Möglichkeiten die erfindungsgemäße Vorrichtung zur Bandbearbeitung auszugestalten und weiterzubilden. Hierzu wird beispielsweise verwiesen einerseits auf die dem Patentanspruch 1 nachgeordneten Patentansprüche andererseits auf die Beschreibung einesThere are now a multitude of possibilities for designing and developing the device for strip processing according to the invention.

Der in Fig. 1 dargestellte Ausschnitt einer erfindungsgemäßen Vorrichtung zur Bandbearbeitung zeigt weder eine Abhaspei- noch eine Aufhaspelstation, deren Konstruktion jedoch an sich bekannt ist. Als Bandbearbeitungsstation ist unter anderem eine Rollenschere 1 zum Besäumen eines nicht dargestellten Bandes dargestellt. Erfindungsgemäß ist zwischen den nicht dargestellten Ab- und Aufhaspelstationen eine die Bandkanten des ebenfalls nicht dargestellten Bandes reckende Bandkantenreckstation 2 dargestellt.The section shown in Fig. 1 of a device for strip processing according to the invention shows neither a rewinding nor a reeling station, the construction of which is known per se. A roller shear 1 for trimming a strip (not shown) is shown as a strip processing station. According to the invention, a strip edge stretching station 2 stretching the strip edges of the strip, also not shown, is shown between the unwinding and reeling stations.
Wie aus Fig. 1 ersichtlich ist, weist die Bandkantenreckstation 2 zwei seitlich in das nicht dargestellte Band eingreifende Bandkantenreckeinheiten 3 auf, wobei jede der Bandkantenreckeinheiten 3 jeweils drei, in Fig. 1 nur teilweise sichtbare, Bandkantenumlenkrollen 4 aufweist.As can be seen from FIG. 1, the strip edge stretching station 2 has two strip edge stretching units 3 which engage laterally in the strip (not shown), each of the strip edge stretching units 3 each having three strip edge deflection rollers 4, which are only partially visible in FIG. 1.
In Fig. 1 ist weiter dargestellt, daß die Bandkantenreckeinheiten in der Bandebene, senkrecht zur
Bandlaufrichtung auf Führungen 5 verschiebbar angeordnet sind. Bei dem in Fig. 1 dargestellten Ausführungsbeispiel erfolgt die Verschiebung der Bandkantenreckeinheiten 3 auf den Führungen 5 manuell. Alternativ ist es ohne weiteres denkbar, die Bandkantenreckeinheiten auf entsprechenden Führungen mit einem entsprechendem Antrieb automatisch zuzustellen.In Fig. 1 it is further shown that the strip edge stretching units in the strip plane, perpendicular to Tape running direction on guides 5 are slidably arranged. In the exemplary embodiment shown in FIG. 1, the band edge stretching units 3 on the guides 5 are shifted manually. Alternatively, it is easily conceivable to automatically feed the belt edge stretching units on corresponding guides with a corresponding drive.
In Fig. 2 ist eine Bandkantenreckeinheit 3 in einer vergrößerten perspektivischen Ansicht dargestellt. Man erkennt in Fig. 2 besonders deutlich die drei Bandkantenumlenkrollen 4, die Rollenwellen 6 und teilweise eine Führung 5. Aus der Darstellung in Fig. 3 ist ersichtlich, daß die oberste der2 shows a band edge stretching unit 3 in an enlarged perspective view. 2 shows the three band edge deflection rollers 4, the roller shafts 6 and partially a guide 5. From the illustration in FIG. 3 it can be seen that the top of the
Bandkantenumlenkrollen 4 über eine Stellschraube 7 in ihrer Eintauchtiefe gegenüber den unteren der Bandkantenumlenkrollen 4, also senkrecht zur Bandebene, einstellbar ist. Über diese Eintauchtiefe wird die Schleife eingestellt, in der das in Fig. 3 strichpunktiert dargestellte Band 8 durch die Bandkantenreckeinheit 3 läuft.Belt edge deflection rollers 4 can be adjusted by means of an adjusting screw 7 in their immersion depth relative to the lower ones of the belt edge deflection rollers 4, that is to say perpendicular to the belt plane. The loop in which the band 8 shown in broken lines in FIG. 3 runs through the band edge stretching unit 3 is set via this immersion depth.
Aus der Bandlaufrichtung gesehen erkennt man in Fig. 4 besonders deutlich, daß die Bandkantenumlenkrollen 4 kegelstumpfförmig ausgebildet sind, was zu einem unterschiedlichen Grad an Reckung der Bandkante in Abhängigkeit vom Abstand vom Rand des Bandes führt. Weiter ist aus Fig. 4 ersichtlich, daß die Bandkantenumlenkrollen 4 vorzugsweise über zwei Lager 9 gegenüber der Rollenwelle 6 gelagert sind, um die nicht unerheblichen Radialkräfte beim Bandtransport aufzunehmen.
4, it can be seen particularly clearly in FIG. 4 that the strip edge deflection rollers 4 are frustoconical, which leads to a different degree of stretching of the strip edge depending on the distance from the edge of the strip. It can also be seen from FIG. 4 that the belt edge deflection rollers 4 are preferably mounted opposite the roller shaft 6 via two bearings 9 in order to absorb the not inconsiderable radial forces during the belt transport.
