VORRICHTUNG UND VERFAHREN ZUR BANDKANTENSTABILISIERUNGDEVICE AND METHOD FOR BAND EDGE STABILIZATION
Technisches GebietTechnical area
Die Erfindung betrifft eine Vorrichtung zur Bandkantenstabilisierung und ein Verfahren hierfür.The invention relates to a device for strip edge stabilization and a method for this.
Stand der TechnikState of the art
in modernen Verzinkungsanlagen wird das zu verzinkende Bandmaterial durch ein zinkhaltiges Bad geleitet, so dass sich ein Zinkfilm auf dem Bandmaterial bildet. Das dabei überschüssige Zinkmaterial wird anschließend mit einem pneumatischen Abstreifer wieder entfernt, so dass eine Materialeinsparung realisiert werden kann und eine gewünschte gleichmäßige Auflagedicke des Zink- materials erreicht werden kann.In modern galvanizing plants, the strip material to be galvanized is passed through a zinc-containing bath, so that a zinc film is formed on the strip material. The excess zinc material is then removed again with a pneumatic scraper, so that a material saving can be realized and a desired uniform contact thickness of the zinc material can be achieved.
Die Abstreifer müssen daher sehr dicht an das Bandmaterial herangeführt werden, damit der gezielte Zinkfilm erreichbar ist.The scrapers must therefore be brought very close to the strip material so that the targeted zinc film can be reached.
Nun stellt es sich jedoch immer wieder heraus, dass Bandwelligkeiten verhindern, dass die Abstreifer optimal an das Bandmaterial herangeführt werden können. So erzeugen Schwingungen, Querbögen und Randwellen Wellen des Bandmaterials, die dazu führen würden, dass die Abstreifer in diesen Bereichen auch zu viel oder zu wenig Zinkmaterial abtragen würden. Daher sind in der letzten Zeit elektromagnetische Bandstabilisatoren bekannt geworden, siehe WO 2006/021436 A1 , die über die Breite der Anlage zur Verzinkung eines Ban- des verteilt angeordnet sind, wobei auf solchen Anlagen verschiedene Bandbreiten bearbeitet und verzinkt werden, so dass die fest angeordneten Bandstabilisatoren nicht im Bereich der jeweiligen Bandränder angeordnet sind und somit dort keine vernünftige Wirkung zeigen und somit im Randbereich weiterhin störende Wellungen des Bandmaterials auftreten.However, it turns out again and again that belt ripples prevent the scrapers from being optimally guided to the strip material. Thus, vibrations, transverse arches and edge waves create waves of the strip material that would cause the scrapers in these areas would also remove too much or too little zinc material. Therefore, electromagnetic band stabilizers have become known in recent times, see WO 2006/021436 A1, which covers the width of the system for galvanizing a banana distributed, wherein on such systems different bandwidths are processed and galvanized, so that the fixed band stabilizers are not located in the region of the respective band edges and thus there have no reasonable effect and thus disturbing curls of the strip material continue to occur in the edge region.
Darstellung der Erfindung, Aufgabe, Lösung, VorteilePresentation of the invention, object, solution, advantages
Es ist die Aufgabe der vorliegenden Erfindung, eine Vorrichtung und ein Verfah- ren zur Bandkantenstabilisierung zu schaffen, mittels welcher die Nachteile des Standes der Technik überwunden oder vermindert werden können.It is the object of the present invention to provide an apparatus and a method for strip edge stabilization, by means of which the disadvantages of the prior art can be overcome or reduced.
Erfindungsgemäß wird die Aufgabe bezüglich der Vorrichtung erreicht durch eine Vorrichtung zur Bandkantenstabilisierung eines Bandes, welche zumindest einen Sensor aufweist zur Erkennung der Position der zumindest einen Bandkante und zumindest eine Verstellvorrichtung vorgesehen ist, mittels welcher in Abhängigkeit der erkannten Position der zumindest einen Bandkante zumindest ein Mittel zur Bandkantenstabilisierung positionierbar ist. Vorteilhaft ist, wenn zwei Sensoren vorhanden sind, welche die Positionen der beiden Bandkanten detektieren. Damit können dann an beiden Bandkanten die Bandkantenstabilisierungen optimal positioniert werden.According to the invention, the object with respect to the device is achieved by a device for strip edge stabilization of a strip which has at least one sensor for detecting the position of the at least one band edge and at least one adjusting device is provided, by means of which depending on the detected position of the at least one band edge at least one means is positionable for band edge stabilization. It is advantageous if two sensors are present, which detect the positions of the two band edges. Thus, the band edge stabilization can then be optimally positioned at both edges of the strip.
Dabei ist es vorteilhaft, wenn das Mittel zur Bandkantenstabilisierung zumindest eine Spule zur Erzeugung eines elektromagnetischen Feldes, wie elektromag- netischen Wechselfeldes, umfasst.It is advantageous if the means for band edge stabilization comprises at least one coil for generating an electromagnetic field, such as electromagnetic alternating field.
Auch ist es vorteilhaft, wenn das Mittel zur Bandkantenstabilisierung zumindest eine Spule pro Bandkante zur Erzeugung eines elektromagnetischen Feldes, wie elektromagnetischen Wechselfeldes, umfasst. Auch ist es zweckmäßig, wenn das Mittel zur Bandkantenstabilisierung zumindest zwei Spulen umfasst, die an einer Bandkante gegenüberliegend oberhalb und unterhalb des Bandes angeordnet sind. So läuft die Bandkante quasi zwischen den sich gegenüberliegenden Spulen hindurch.It is also advantageous if the means for band edge stabilization comprises at least one coil per band edge for generating an electromagnetic field, such as alternating electromagnetic field. It is also expedient if the means for band edge stabilization comprises at least two coils which are arranged on a band edge opposite above and below the band. So the band edge runs quasi between the opposite coils.
Weiterhin ist es vorteilhaft, wenn die Verstellvorrichtung einen Verstellantrieb aufweist. Auch ist es zweckmäßig, wenn der Verstellantrieb ein elektromotorischer, pneumatischer oder hydraulischer Antrieb ist.Furthermore, it is advantageous if the adjusting device has an adjusting drive. It is also expedient if the adjustment drive is an electromotive, pneumatic or hydraulic drive.
Vorteilhaft ist es auch, wenn weiterhin zumindest ein Abstreifer vorgesehen ist, um Material von dem Band abzustreifen und die Verstellvorrichtung mit einer Vorrichtung zur Einstellung des zumindest einen Abstreifers vorzugsweise als Baueinheit verbunden ist. Auch können die beiden Vorrichtungen getrennt ausgebildet sein.It is also advantageous if at least one scraper is further provided to strip material from the belt and the adjusting device is preferably connected to a device for adjusting the at least one scraper as a structural unit. Also, the two devices may be formed separately.
Erfindungsgemäß wird die Aufgabe bezüglich des Verfahrens erreicht durch ein Verfahren zur Steuerung einer Vorrichtung zur Bandkantenstabilisierung eines Bandes, wobei zumindest ein Sensor die Position einer Bandkante detektiert und zumindest eine Verstellvorrichtung derart angesteuert wird, dass in Abhängigkeit der erkannten Position der zumindest einen Bandkante zumindest ein Mittel zur Bandkantenstabilisierung positioniert wird.According to the invention, the object with respect to the method is achieved by a method for controlling a device for strip edge stabilization of a strip, wherein at least one sensor detects the position of a strip edge and at least one adjustment device is controlled such that depending on the detected position of the at least one band edge at least one means is positioned for band edge stabilization.

Bevorzugte Ausführung der ErfindungPreferred embodiment of the invention
Die Figuren 1 , 2 und 3 zeigen jeweils eine Skizze einer erfindungsgemäßen Vorrichtung 1 zur Bandkantenstabilisierung. Dabei ist ein Band 2, wie bei- spielsweise ein Metall- oder Stahlband dargestellt, welches vorzugsweise mittels Transportmitteln transportierbar ist. Das Band 2 weist zwei seitliche Bandkanten 3,4 auf. Zur Führung des Bandes sind in dem Bad des Beschichtungs- materials (Schmelze) Rollen vorgesehen, wie dies in den Figuren 4 und 5 veranschaulicht ist. Ein Führungsmittel 5 dient zur Führung und als Bewegungs- ebene für eine Verstellvorrichtung 7. Weiterhin ist zumindest ein Sensor 6 vorgesehen, welcher die aktuelle Bandlage des Bandes 2 mit seinen Bandkanten 3,4 erfasst. Auch können über die Breite des Bandes 2 mehrere Sensoren 6 vorgesehen sein, wie beispielsweise zwei Sensoren 6 auf gegenüberliegenden Seiten der Bandmitte oder der Mitte der Bandführung oder an beiden Rändern des Bandes. Mit 10 ist das Zink- oder ein anderes Beschichtungsmittelbad bezeichnet, durch welches das Band durchläuft um damit beschichtet zu werden. Darüber hinaus ist eine Verstellvorrichtung 7 mit einem Verstellantrieb 7a vorgesehen, welche die Mittel 8 zur Bandkantenstabilisierung verstellt. Diese Verstellung kann in Abhängigkeit der Lage der Bandkanten 3,4 erfolgen, also vorzugsweise in einer Richtung quer zur Längsrichtung des Bandes. Durch die De- tektion bzw. Erfassung der Lage der Bandkanten 3,4 durch den oder die Sensoren 6 kann durch die Verstellvorrichtung 7 das oder die Mittel 8 zur Bandkantenstabilisierung derart positioniert werden, dass es bzw. sie jeweils im Bereich einer oder der Bandkanten 3,4 angeordnet ist bzw. sind. Die Mittel zur Bandkantenstabilisierung können vorzugsweise an einer Bandkante oder an beiden gegenüberliegenden Bandkanten vorgesehen sein.Figures 1, 2 and 3 each show a sketch of a device 1 according to the invention for band edge stabilization. In this case, a band 2, such as, for example, a metal or steel band is shown, which is preferably transportable by means of transport. The band 2 has two lateral band edges 3,4. To guide the band rollers are provided in the bath of the coating material (melt), as illustrated in Figures 4 and 5. Furthermore, at least one sensor 6 is provided which detects the current band position of the band 2 with its band edges 3, 4. Also, a plurality of sensors 6 may be provided across the width of the tape 2, such as two sensors 6 on opposite sides of the tape center or the middle of the tape guide or on both edges of the tape. Denoted at 10 is the zinc or other coating agent bath through which the belt passes to be coated therewith. In addition, an adjusting device 7 is provided with an adjusting drive 7a, which adjusts the means 8 for strip edge stabilization. This adjustment can be made in dependence on the position of the band edges 3,4, that is preferably in a direction transverse to the longitudinal direction of the band. As a result of the detection or detection of the position of the band edges 3, 4 by the sensor or sensors 6, the adjusting device 7 can position the band edge stabilizing means or means 8 in such a way that they respectively in the region of one or the band edges 3 , 4 is arranged or are. The means for stabilizing the strip edge may preferably be provided on a band edge or on both opposite band edges.
Als Mittel zur Bandstabilisierung 8 dient vorzugsweise eine Anordnung mit zumindest einer Spule, welche beispielsweise Randwellen der Bandkante dämpfen kann. Auch können an einer Bandkante 3,4 zwei Spulen 8 vorgesehen sein, die gegenüberliegend angeordnet sind, so dass die Bandkante 3,4 zwischen den beiden Spulen 8 angeordnet ist und den Spalt zwischen den Spulen 8 durchläuft.As a means for band stabilization 8 is preferably an arrangement with at least one coil, which can dampen, for example, edge waves of the band edge. Also, two coils 8 can be provided at a band edge 3,4, which are arranged opposite one another, so that the band edge 3,4 is arranged between the two coils 8 and passes through the gap between the coils 8.
Weiterhin weist ein vorteilhaftes Ausführungsbeispiel der Vorrichtung 1 eine Kantenmaske 9 der Verzinkungsvorrichtung oder der Beschichtungsvorrichtung auf. Die Kantenmaske kann - genauso wie die Spulen - der Bandkante nachführbar ausgebildet sein. Die Kantenmaske kann eine Verminderung der Geräuschentwicklung und ein verbessertes Abstreifergebnis des Beschichtungs- materials auf dem Band 2 im Randbereich des Bandes bewirken.Furthermore, an advantageous embodiment of the device 1 has an edge mask 9 of the galvanizing device or the coating device. The edge mask can - like the coils - the band edge be formed trackable. The edge mask can cause a reduction in the noise and an improved wiping result of the coating material on the belt 2 in the edge region of the belt.
Zur Abstreifung des überschüssigen Beschichtungsmittels sind Abstreifer 11 oder Abstreifdüsen vorgesehen, mittels welchen das überschüssige Beschich- tungsmaterial bis auf eine vorgebbare Schichtdicke von dem Band 2 abgetragen wird. Die Abstreifdüsen können vorzugsweise als pneumatische Düsen ausgebildet sein, die sich zumindest über einen Teilbereich der Breite des Bandes erstrecken. Gemäß der Erfindung sind die Sensoren 6 dazu geeignet, um die Lage einer Bandkante oder beider Bandkanten 3,4 zu detektieren. Anhand des Verstellantriebes 7a der Verstellvorrichtung 7 werden die Mittel 8 zur Bandstabilisierung an die Position verfahren, wo die Bandkanten 3,4 gemäß Erkennung angeord- net sind, so dass die Mittel 8 erreichen, dass die Welligkeit der Bandkanten beim Durchlauf durch die Abstreifer reduziert ist und das Band bzw. die Bandkanten möglichst glatt an dem Abstreifer vorbei laufen.Wipers 11 or wiping nozzles are provided for wiping off the excess coating agent, by means of which the excess coating material is removed from the belt 2 up to a predefinable layer thickness. The wiping nozzles may preferably be designed as pneumatic nozzles which extend over at least a portion of the width of the tape. According to the invention, the sensors 6 are suitable for detecting the position of a band edge or both band edges 3, 4. On the basis of the adjusting drive 7a of the adjusting device 7, the belt stabilizing means 8 are moved to the position where the belt edges 3, 4 are arranged according to detection, so that the means 8 achieve that the waviness of the belt edges is reduced when passing through the scrapers and run the tape or the band edges as smooth as possible on the scraper over.
Bevorzugt sind der Verstellantrieb 7a oder die Verstellantriebe 7a als elektro- motorische Mittel und/oder hydraulische Mittel und/oder pneumatische Mittel ausgebildet, welche vorzugsweise angesteuert betätigt werden. Zur Steuerung der Positionierung der Verstellmittel durch die Verstellantriebe 7a dient weiterhin eine Steuereinheit, welche den oder die Verstellantriebe 7a in Abhängigkeit der Bandkantenposition ansteuert, um die Mittel 8 zur Bandkantenstabilisierung an die detektierte Position der Bandkante 3,4 zu verfahren.Preferably, the adjusting drive 7a or the adjusting drives 7a are designed as electric motor means and / or hydraulic means and / or pneumatic means, which are preferably operated actuated. For controlling the positioning of the adjusting means by the adjusting drives 7a further serves a control unit which controls the one or more adjusting drives 7a in response to the strip edge position to move the means 8 for strip edge stabilization to the detected position of the band edge 3.4.
Darüber hinaus kann die Verstelleinheit der Mittel 8 zur Bandkantenstabilisierung mit den Mitteln zur Höhenverstellung der Abstreifer als Baueinheit zusam- mengefasst sein. Diese Mittel dienen der Höhenverstellung der Abstreifer. Die Höhenverstellung der Abstreifdüsen dient dazu, die Abstreifdüsen in eine optimale Abblasposition zu bringen.In addition, the adjustment unit of the means 8 for strip edge stabilization can be combined with the means for adjusting the height of the scrapers as a structural unit. These means are used to adjust the height of the scrapers. The height adjustment of the wiping nozzles serves to bring the wiping nozzles in an optimal blow-off position.
Beispiel:Example:
Bei langsamer Anlagengeschwindigkeit legt das Band einen geringeren Weg pro Zeiteinheit von der Badoberfläche bis zum Abstreifpunkt zurück. Das Zink ist relativ schnell fester. Darum muss die Düse direkt über das Bad in einer Höhe h1 positioniert werden; siehe Fig. 6.At slow line speeds, the belt travels a lesser distance per unit of time from the bath surface to the stripper point. The zinc is relatively fast solid. Therefore, the nozzle must be positioned directly over the bath at a height h1; see Fig. 6.
Läuft die Anlage schnell, werden die Abstreifdüsen höher, d. h. h2 > h1 , über dem Bad eingestellt, da die Erstarrung später erfolgt; siehe Fig. 7. BezugszeichenlisteIf the system is running fast, the wiping nozzles are set higher, ie h2> h1, above the bath, as the solidification takes place later; see Fig. 7. LIST OF REFERENCE NUMBERS
