Definitions
- the invention relates to a device for strip processing with at least one unwinding station, at least one band processing station and at least one coiling station, wherein between the unwinding station and the coiling station a band edge of the band stretching band edge stretching station is provided. Furthermore, the invention relates to a method for strip processing.
- the strip processing involves trimming a strip
- the strip is unwound from a coil in an uncoiling station, fed to the trimming station, trimmed in the trimming station by a trimming knife, and then reeled from a coiling station onto a coil.
- generic devices for strip processing are also used for sharing, cold rolling or the like.
- this strip is usually subjected to a plurality of rolling passes. Over the greater part 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, besides the effect of increasing the strip length during rolling, the bandwidth increase occurs. Due to the increase in the width of the tape at the edge of the tape is less material for the Increase in the tape length at the edge of the tape available, resulting in that in the band a more or less high band edge tension arises. The band edge tension described leads to various problems in the further band processing.
- a high strip edge tension during the rolling process means that a higher roll energy must be applied to overcome the strip edge tension at each roll pass than would be necessary if the strip edge tension were completely removed. If the strip edge tension can therefore be reduced between two rolling passes, the required roll energy is reduced during the second pass.
- US Pat. No. 3,854,315 discloses an apparatus for trimming or leveling elongated metal strips of different widths, in which strips of a plurality of different widths can be machined, the setting of the device being carried out by hand, which is very expensive. Another disadvantage is that in this device it is not possible to optimally take into account the voltage profiles in the band edge. Furthermore, due to the large dimensions of this device, a lot of space is needed to set up the device.
- the present invention has the object to provide a device for tape processing available, which has small dimensions, is easily adjustable and beyond a targeted, depending on the distance from the band edges stretching allowed.
- the band edge stretching station has two laterally engaging in the band band edge stretching units and a strip edge stretching unit each having at least three Bandkantenumlenkrollen, the Bandkantenumlenkrollen substantially perpendicular to the band plane are mutually adjustable, the Bandkantenumlenkrollen frusto-conical are and the band edge stretching units are arranged displaceably in the band plane perpendicular to the strip running direction.
- the Bandkantenumlenkrollen are mutually adjustable substantially perpendicular to the belt plane, the enforced via the Bandkantenumlenkrollen loop can be adjusted, which in turn the degree of stretching is adjustable.
- the frusto-conical configuration of the band edge deflection rollers simplifies the threading of the band edges between the band edge deflection rollers and ensures that an increasing stretching takes place toward the edge of the band, thereby taking into account the stress gradient in the band edge.
- Other thickness profiles for the band edge deflection rollers are also conceivable which are each adapted to the desired stretching course.
- the strip edge stretching devices are arranged displaceably in the strip plane perpendicular to the strip running direction, the depth of insertion of the strip edge deflection rolls can be adjusted into the strip and thus the area of the strip edges which is stretched can vary.
- the strip processing device according to the invention is particularly suitable for processing strips of aluminum materials, since due to the work hardening properties of aluminum during cold rolling of aluminum strips, particularly high strip edge stresses occur.
- the strip processing can consist in particular exclusively in stretching the strip edges of the strip.
- a strip edge stretching station would be, for example, subjecting the strip edges to a separate rolling pass, which preferably does not involve processing of the strip between the strip edges. It is conceivable, for example, the arrangement of two short rollers in the region of the strip edges, which specifically roll, for example, in cooperation with a deflection roller in the rolling mill, the strip edges, whereby the strip edge stresses are reduced.
- an embodiment of the device according to the invention for strip processing has proved to be particularly advantageous in which the strip edge stretching station has two strip edge stretching units engaging laterally in the strip and a strip edge stretching unit has at least three strip edge deflection rolls.

About this immersion depth, the loop is set in which the band 8 shown in phantom in Fig. 3 by the band edge stretching unit 3 runs.
- the Bandkantenumlenkrollen 4 are frusto-conical, resulting in a different degree of stretching of the strip edge in dependence on the distance from the edge of the strip.
- the Band edge deflection rollers 4 are preferably mounted on two bearings 9 relative to the roller shaft 6 to accommodate the not inconsiderable radial forces during belt transport.

Description
Die Erfindung betrifft eine Vorrichtung zur Bandbearbeitung mit mindestens einer Abhaspelstation, mindestens einer Bandbearbeitungsstation und mindestens einer Aufhaspelstation, wobei zwischen der Abhaspelstation und der Aufhaspelstation eine die Bandkanten des Bandes reckende Bandkantenreckstation vorgesehen ist. Weiter betrifft die Erfindung ein Verfahren zur Bandbearbeitung.The invention relates to a device for strip processing with at least one unwinding station, at least one band processing station and at least one coiling station, wherein between the unwinding station and the coiling station a band edge of the band stretching band edge stretching station is provided. Furthermore, the invention relates to a method for strip processing.
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 strip processing involves trimming a strip, the strip is unwound from a coil in an uncoiling station, fed to the trimming station, trimmed in the trimming station by a trimming knife, and then reeled from a coiling station onto a coil. In addition to trimming generic devices for strip processing are also used for sharing, 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 dazu führt, dass im Band eine mehr oder weniger hohe 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 rolling passes. Over the greater part 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, besides the effect of increasing the strip length during rolling, the bandwidth increase occurs. Due to the increase in the width of the tape at the edge of the tape is less material for the Increase in the tape length at the edge of the tape available, resulting in that in the band a more or less high band edge tension arises. The band edge tension described leads to various problems in the further band processing. So it comes, for example, in the production of Dosenbodyband, which is processed in further processing steps for beverage can body, by the band in this band usually very high strip edge tension during trimming to an undesirable edge extension by friction of the cut edges on Besäummesser. This undesirable edge extension leads on the one hand to a so-called starburst or star pattern formation on the coiled coil 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 tape it comes in the case of further processing stretching occasionally to tape cracks, which have their origin, inter alia, that the band edges of the further processing supplied can lid tape have a high band edge tension and thus promote cracking 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 a higher roll energy must be applied to overcome the strip edge tension at each roll pass than would be necessary if the strip edge tension were completely removed. If the strip edge tension can therefore be reduced between two rolling passes, the required roll energy is reduced during the second pass.
Aus der US-A 3 854 315 ist eine Vorrichtung zum Zurichten oder Egalisieren von langgestreckten Metallstreifen unterschiedlicher Breite bekannt, bei der Streifen mit mehreren verschiedenen Breiten bearbeitet werden können, wobei die Einstellung der Vorrichtung per Hand durchgeführt wird, was sehr aufwendig ist. Nachteilig ist weiter, dass es bei dieser Vorrichtung nicht möglich ist, die Spannungsverläufe in der Bandkante optimal zu berücksichtigen. Des Weiteren wird aufgrund der großen Abmessungen dieser Vorrichtung sehr viel Platz zur Aufstellung der Vorrichtung benötigt.US Pat. No. 3,854,315 discloses an apparatus for trimming or leveling elongated metal strips of different widths, in which strips of a plurality of different widths can be machined, the setting of the device being carried out by hand, which is very expensive. Another disadvantage is that in this device it is not possible to optimally take into account the voltage profiles in the band edge. Furthermore, due to the large dimensions of this device, a lot of space is needed to set up the device.
Ausgehend von dem zuvor beschriebenen Stand der Technik liegt der vorliegenden Erfindung die Aufgabe zugrunde, eine Vorrichtung zur Bandbearbeitung zur Verfügung zu stellen, die kleine Abmessungen aufweist, leicht einstellbar ist und darüber hinaus ein gezieltes, vom Abstand von den Bandkanten abhängiges Recken erlaubt.Based on the above-described prior art, the present invention has the object to provide a device for tape processing available, which has small dimensions, is easily adjustable and beyond a targeted, depending on the distance from the band edges stretching allowed.
Gemäß der Lehre der Erfindung ist die zuvor hergeleitete und aufgezeigte Aufgabe dadurch gelöst, dass die Bandkantenreckstation zwei seitlich in das Band eingreifende Bandkantenreckeinheiten aufweist und eine Bandkantenreckeinheit jeweils mindestens drei Bandkantenumlenkrollen aufweist, die Bandkantenumlenkrollen im wesentlichen senkrecht zur Bandebene gegeneinander einstellbar sind, die Bandkantenumlenkrollen kegelstumpfförmig ausgebildet sind und die Bandkantenreckeinheiten in der Bandebene senkrecht zur Bandlaufrichtung verschiebbar angeordnet sind. 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 teachings of the invention, the previously derived and indicated object is achieved in that the band edge stretching station has two laterally engaging in the band band edge stretching units and a strip edge stretching unit each having at least three Bandkantenumlenkrollen, the Bandkantenumlenkrollen substantially perpendicular to the band plane are mutually adjustable, the Bandkantenumlenkrollen frusto-conical are and the band edge stretching units are arranged displaceably in the band plane perpendicular to the strip running direction. By means of the band edge stretching station according to the invention, it is possible to reduce the strip edge tension to the desired extent or even to selectively produce a band edge overstretching. By the targeted reduction of the strip edge tension, for example, the described above, known from the prior art problems in the band processing reduced or even completely eliminated.
Dadurch, dass 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.Characterized in that the Bandkantenumlenkrollen are mutually adjustable substantially perpendicular to the belt plane, the enforced via the Bandkantenumlenkrollen loop can be adjusted, which in turn the degree of stretching is adjustable.
Durch die kegelstumpfförmige Ausbildung der Bandkantenumlenkrollenvereinfacht 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.The frusto-conical configuration of the band edge deflection rollers simplifies the threading of the band edges between the band edge deflection rollers and ensures that an increasing stretching takes place toward the edge of the band, thereby taking into account the stress gradient in the band edge. Of course, other thickness profiles for the band edge deflection rollers are also conceivable which are each adapted to the desired stretching course.
Dadurch schließlich, 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.Finally, as a result of the fact that the strip edge stretching devices are arranged displaceably in the strip plane perpendicular to the strip running direction, the depth of insertion of the strip edge deflection rolls can be adjusted into the strip and thus the area of the strip edges which is stretched can vary.
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 strip processing device according to the invention is particularly suitable for processing strips of aluminum materials, since due to the work hardening properties of aluminum during cold rolling of aluminum strips, particularly high strip edge stresses occur.
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.In a device for strip processing according to the invention, the strip processing can consist in particular exclusively in stretching the strip edges of the strip. However, it is usually advantageous to connect the stretching of the strip edges of the strip with at least one further processing step, for example the trimming of the strip, in a device for strip processing.
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.One possibility for constructing a strip edge stretching station according to the invention would be, for example, subjecting the strip edges to a separate rolling pass, which preferably does not involve processing of the strip between the strip edges. It is conceivable, for example, the arrangement of two short rollers in the region of the strip edges, which specifically roll, for example, in cooperation with a deflection roller in the rolling mill, the strip edges, whereby the strip edge stresses 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 according to the invention for strip processing has proved to be particularly advantageous in which the strip edge stretching station has two strip edge stretching units engaging laterally in the strip and a strip edge stretching unit has at least three strip edge deflection rolls. In such a belt edge stretching station, the belt edges are stretched by not passing straight in the belt transporting direction between the belt edge deflection rollers, but being looped over the belt edge deflection rollers which result in stretching of the belt edges due to path extension for the belt edges. Such a band edge stretching station is very constructive simple and easy to integrate into existing tape processing equipment.
Gemäß der Lehre der Erfindung betrifft die Erfindung auch ein Verfahren zur Bandbearbeitung, bei welchem das Band von einem Coil abgehaspelt wird und in einer Aufhaspelstation auf ein Coil aufgehaspelt wird, wobei die Bandkanten des Bandes zwischen der Abhaspelstation und der Aufhaspelstation in einer Bandkantenreckstation gereckt werden, unter Verwendung einer oben beschriebenen Vorrichtung.According to the teachings of the invention, the invention also relates to a method of tape processing in which the tape is unwound from a coil and reeled on a coil in a coiling station, the tape edges of the tape being stretched between the uncoiling station and the coiling station in a band edge stretching station. using a device described above.
Die oben hergeleitete und aufgezeigte Aufgabe wird gemäß der zweiten Lehre der Erfindung dadurch gelöst, dass die Bandkanten des Bandes jeweils über mindestens drei senkrecht zur Bandebene, auf senkrecht zur Bandlaufrichtung verschiebbaren, jeweils seitlich in das Band eingreifenden Bandkantenreckeinheiten einer Bandkantenreckstation angeordneten, gegeneinander einstellbaren, kegelstumpfförmigen Bandkantenumlenkrollen in einer größenvariabel einstellbaren Schleife geführt werden, wobei der zu reckende Bereich der Bandkanten über eine Verschiebung der Bandkantenreckeinheiten senkrecht zur Bandlaufrichtung eingestellt wird und wobei das Band zum Rand hin stärker gereckt wird.The above-derived and indicated object is achieved according to the second teaching of the invention in that the band edges of the band arranged in each case over at least three perpendicular to the belt plane, displaceable perpendicular to the strip running direction, each laterally engaging in the band strip edge stretching units of a Bandkantenreckstation, mutually adjustable, frustoconical Band edge deflection rollers are guided in a variable-size adjustable loop, wherein the stretched area of the strip edges is adjusted via a displacement of the strip edge stretching units perpendicular to the strip running direction and wherein the strip is stretched towards the edge stronger.
Zu den Vorteilen des Verfahrens gemäß der Lehre der Erfindung kann auf die oben aufgeführten Vorteile der Vorrichtung verwiesen werden.For the advantages of the method according to the teaching of the invention, reference may be made to the above-mentioned advantages of the device.
