To this end, the strip is guided over a tension roller for a strip treatment installation, and the traction exerted on the strip is increased or reduced between the feeding point of the tension roller and the delivery point of the tension roller, a measuring sensor arranged on the periphery of the tension roller being used to detect the tension distribution in the strip.

Description

"Spannrolle für eine Bandbehandlungsanlage sowie Bandbehandlungsanlage und Verwendung einer Spannrolle" "Tensioning roller for a belt treatment plant and strip treatment plant and use of a tensioning roller"
Die Erfindung betrifft eine Spannrolle für eine Bandbehandlungsanlage, bei der das Band über die Spannrolle geführt wird und der Bandzug durch die Spannrolle zwischen dem Einlauf auf die Spannrolle und dem Auslauf von der Spannrolle erhöht bzw. verringert wird. Ferner betrifft die Erfindung eine Bandbehandlungsanlage sowie die Verwendung einer Spannrolle.The invention relates to a tension roller for a belt treatment plant, in which the belt is guided over the tension roller and the belt tension is increased or reduced by the tension roller between the inlet to the tension roller and the outlet of the tension roller. Furthermore, the invention relates to a strip processing plant and the use of a tensioning roller.
In Bandbehandlungsanlagen, wie beispielsweise Anlagen zum Streckbiege¬ richten oder Zugrecken von Bandmaterial, Walzwerken oder dergleichen wird das die Bandbehandlungsanlage durchlaufende Band mit einer Bandzugkraft beaufschlagt. Dies kann mit Spannrollen durchgeführt werden. Diese Spann¬ rollen sind in der Regel motorisch angetrieben und verzögern bzw. beschleu¬ nigen das Band durch Übertragung von Reibungskräften. Durch die Verzöge¬ rung des Bands kann der Bandzug nach der Spannrolle erhöht werden. Durch eine Beschleunigung des Bands kann der Bandzug nach der Spann¬ rolle reduziert werden.In strip processing plants, such as plants for stretch bending or stretching of strip material, rolling mills or the like, the band passing through the strip processing plant is subjected to a strip tensile force. This can be done with tension rollers. As a rule, these tension rollers are driven by a motor and retard or accelerate the belt by transmitting frictional forces. By delaying the tape, the strip tension can be increased after the tensioning roller. By an acceleration of the belt, the strip tension can be reduced to the tension roller.
Eine Art der Bandbehandlungsanlagen sind Bandrichtanlagen, die zur Be¬ seitigung der Unplanheit eingesetzt werden. Durch plastisches Dehnen der kürzeren Bandanteile im Band wird ein Längenausgleich erreicht und werden somit zum Beispiel Mitten- oder Randwellen entfernt. Dabei werden Bandab- schnitte, die vor dem Richtvorgang verschieden lang und daher teilweise wellig waren, unterschiedlich plastisch gelängt.One type of belt treatment plants are strip straightening systems which are used to eliminate unevenness. By plastic stretching the shorter band shares in the band, a length compensation is achieved and are thus removed, for example, center or edge waves. In doing so, band sections, which were different in length before the straightening process and therefore partly wavy, different plastic elongated.
Für das Richten von Bändern werden häufig kontinuierlich arbeitende Richt- verfahren eingesetzt. Die hierfür verwendeten Bandbehandlungsanlagen weisen regelmäßig einen Einlaufspanntrommelsatz mit Spannrollen auf, in dem der Bandzug gegenüber dem Bandzug in der Linie erhöht wird, eine Reckzone oder ein Streckbiegegerüst und einen Auslaufspanntrommelsatz, in dem der Spannzug wieder auf das Niveau der Linie reduziert wird.For straightening ribbons, continuous straightening methods are often used. The belt treatment plants used for this purpose regularly have an inlet clamping drum set with tension rollers, in which the strip tension is increased in relation to the strip tension in the line, a stretching zone or a stretch bending stand and an outlet tensioning drum set, in which the tensioning cable is reduced again to the level of the line.
Im Streckbiegegerüst wird das Band unter hohem Zug um Biegewalzen klei¬ nen Durchmessers alternierend gebogen. Hierbei wird im Band die Elastizi¬ tätsgrenze überschritten. Durch die Überlagerung der elastoplastischen Bie¬ gung mit dem Bandzug wird eine bleibende Längung, der sogenannte Streckgrad, erzeugt. Beim Zugrecken wird das Band auf einer bestimmten Länge so stark gedehnt, daß der gesamte Bandquerschnitt plastifiziert. Die erforderliche Zugspannung wird durch die Spanntrommelsätze aufgebracht und muß die Streckgrenze des Materials erreichen. Eine Kombination von Zugrecken und Streckbiegerichten wird für bestimmte Produkte wie zum Bei- spiel bei Aluminiumband eingesetzt, da hierdurch häufig bessere Planlage¬ ergebnisse erreicht werden.In the stretch bending stand, the strip is bent alternately at high tension around bending rolls of small diameter. In this case, the elasticity limit is exceeded in the band. The superimposition of the elastoplastic bending with the strip tension produces a permanent elongation, the so-called degree of stretching. When drawing the tape is stretched to a certain length so strong that the entire band cross-section plasticized. The required tension is applied by the tension drum sets and must reach the yield point of the material. A combination of stretching and stretch bending is used for certain products, such as aluminum strip, since this often results in better flatness results.
Je nach Werkstoff, Banddicke, Bandbreite und Typ der Eingangsunplanheit werden für die Zugrollen oder das Streckbiegegerüst überwiegend die Ein- Stellparameter experimentell bestimmt. So ist man auch heute noch beim Betreiben des Richtprozesses weitgehend auf Erfahrungswerte angewiesen.Depending on the material, strip thickness, bandwidth and type of input unevenness, the setting parameters are predominantly determined experimentally for the pull rolls or the stretch bending stand. Thus, even today, the operation of the straightening process relies largely on empirical values.
Bei den Bandrichtverfahren wird das Band unter hohe Längszugspannung gesetzt. Wellen oder Beulen im Band, die ohne angelegten Längszug sicht- bar wären, treten nicht in Erscheinung. Die sich einstellende Zugspannungs¬ verteilung ist daher abhängig von der im Band vorliegenden Längenvertei¬ lung. Dabei übernehmen die kürzeren Bandfasern beim Anlegen einer äuße¬ ren Bandzugspannung höhere Spannungsanteile als längere Bandfasern. Damit die Reckzone und/oder das Biegegerüst optimal eingestellt werden können, ist es erforderlich, die Planheit des Bandes kontinuierlich zu mes¬ sen.In the band straightening process, the band is set under high longitudinal tension. Waves or bumps in the band, which would be visible without a longitudinal tension, do not appear. The resulting tension distribution is therefore dependent on the length distribution present in the belt. In this case, the shorter band fibers assume higher stress components when applying an outer band tensile stress than longer band fibers. In order for the stretching zone and / or the bending stand to be optimally adjusted, it is necessary to measure the flatness of the strip continuously.
Ein Meßverfahren zur Planheitsmessung von Bändern ist aus EP 0 988 904 A2 bekannt. Dort wird ein Verfahren beschrieben, gemäß dem der Bandzug für die Messung der Planheit mittels Spannrollen, sogenannten S-Rollensät- zen, reduziert wird. Eine nach dem Auslauf des Bands aus dem S-Rollensatz angeordnete optische Meßvorrichtung mißt die Bandplanheit in dem nahezu bandzugsfreien Band. Nach der Messung der Bandplanheit wird der Band¬ zug wieder auf den Bandzug der Linie mittels S-Rollensätzen erhöht.A measurement method for flatness measurement of bands is known from EP 0 988 904 A2. There, a method is described according to which the strip tension for measuring the flatness is reduced by means of tensioning rollers, so-called S-roller sets. An optical measuring device arranged after the outlet of the tape from the S-roll set measures the flatness of the tape in the almost belt-tension-free tape. After measuring the band flatness, the band tension is again increased to the strip tension of the line by means of S roll sets.
Für die Ermittlung der Unplanheit des Bands werden in Bandrichtanlagen zunehmend separate Meßrollen eingesetzt. Derartige Meßrollen sind bei- spielsweise aus DE 42 36 657 C2, DE 297 21 085 U1 , DE 102 07 501 C2, DE 18 38 457 A1 , DE 199 18 699 A1 und DE 196 16 980 A1 bekannt. Als Einbauort für die Meßrolle steht die Wahlmöglichkeit, diese entweder in die Reckzone, nach dem Biegegerüst oder nach dem Auslaufspanntrommelsatz zum Beispiel vor der Aufwickeltrommel einzusetzen.To determine the unplanarity of the band increasingly separate measuring rollers are used in Bandrichtanlagen. Such measuring rollers are known, for example, from DE 42 36 657 C2, DE 297 21 085 U1, DE 102 07 501 C2, DE 18 38 457 A1, DE 199 18 699 A1 and DE 196 16 980 A1. The installation location for the measuring roller is the option to use it either in the stretching zone, after the bending stand or after the Auslaufspanntrommelsatz, for example in front of the take-up drum.
Anlagebedingt sind in der Reckzone nach dem Biegegerüst häufig sehr be¬ engte Einbauverhältnisse vorzufinden. Dies wiederum hat zur Folge, daß der einsetzbare Rollendurchmesser für die Meßrolle begrenzt ist. Beim Umlen¬ ken des unter hohem Längszug stehenden Bandes um den Meßrollenkörper werden hohe Biegespannungen in das Band eingeleitet, die in Zusammen¬ wirken mit dem hohen Bandzug einen im Band verbleibenden Formfehler (Längs- oder Querbogen) erzeugen, der für die Weiterverarbeitung des Bandmaterials störend ist. In dieser Einbaulage bewirkt das Messen der Bandplanheit mit einer Meßrolle somit das Einbringen eines weiteren Plan- heitsfehlers und ist deshalb nicht zweckmäßig.Due to the installation, very limited installation conditions are often encountered in the stretching zone after the bending stand. This in turn has the consequence that the usable roll diameter is limited for the measuring roller. When deflecting the strip under high longitudinal tension around the measuring roll body, high bending stresses are introduced into the strip which, in cooperation with the high strip tension, produce a shape defect (longitudinal or transverse bend) remaining in the strip which disturbs the further processing of the strip material is. In this installation position, measuring the flatness of the flat with a measuring roller thus brings about the introduction of a further flatness error and is therefore not expedient.
Zwischen dem Auslaufspanntrommelsatz und der Aufwickeltrommel sind die Einbaubedingungen für die Meßrolle ebenfalls beengt. Wegen des deutlich niedrigeren Bandzugsspannungsniveaus besteht in diesem Anlagenbereich - A -Between the spout drum set and the take-up drum the installation conditions for the measuring roller are also cramped. Because of the significantly lower band tension level exists in this plant area - A -
jedoch die Gefahr der Längs- und Querbogenbildung weniger. Hier ist viel¬ mehr der Einfluß der Wickelgeomtrie beim Aufwickeln des Bandes auf die Aufwickeltrommel von Bedeutung. Beim Aufwickeln von Bändern, deren Querschnittsprofil von der rechteckigen Form abweicht, ergeben sich über der Bandbreite unterschiedliche Wickeid urch messe r. Dieser Effekt tritt in besonderem Maße beim Aufwickeln von sogenanntem Spaltband auf, das durch Längsteilung von warmgewalztem Breitband hergestellt wird. Diese Geometrieabweichungen verursachen bei einem unter Längszug stehenden Band Spannungsumverteilungen über die Bandbreite, die zu einem Anstieg der örtlichen Bandzugspannung von einer Bandseite zur anderen führen. In diesen Fällen ist der oben beschriebene, dem Meßprinzip zugrundeliegende proportionale Zusammenhang zwischen Bandzugspannung und Bandlänge¬ nänderung wegen dieses Störeffekts nicht mehr gegeben. Dieses Meßer¬ gebnis beeinflussende Störspannungen lassen sich nur durch sogenannte "Abschottvorrichtungen" vermeiden, wie sie beispielsweise in DE 199 45 202 A1 beschrieben werden. Die Nachrüstung bestehender Bandrichtanlagen mit solchen Abschottsystemen ist wegen zusätzlichen Platzbedarfs ohne ko¬ stenintensive Umbaumaßnahmen jedoch nicht möglich.However, the risk of longitudinal and transverse bowing less. Here, the influence of the winding geometry when winding the band on the take-up drum is of much more importance. When winding tapes whose cross-sectional profile deviates from the rectangular shape, different thicknesses of thickness are obtained across the bandwidth. This effect occurs particularly when winding up so-called slit strip, which is produced by longitudinal division of hot-rolled broadband. These geometric variations cause tape redistribution across the bandwidth in a longitudinally drawn belt, which results in an increase in local tape tension from one side of the belt to the other. In these cases, the above-described, the measuring principle underlying proportional relationship between the strip tension and Bandlänge¬ change due to this disruptive effect is no longer given. This measuring result influencing interference voltages can be avoided only by so-called "Abschottvorrichtungen", as described for example in DE 199 45 202 A1. However, the retrofitting of existing band straightening systems with such Abschottsystemen is not possible because of additional space without ko¬ most costly conversion measures.
Der Einbau der Meßrolle vor der Aufwickeltrommel führt ferner dazu, daß die Bandbereiche, die im Biegegerüst verformt wurden, erheblich zeit- und lage¬ versetzt über die Meßrolle geführt werden. Diese sogenannte Totstrecke, die je nach Anlagenkonfiguration Längen von bis zu 20 m annehmen kann, führt zu abgewerteten Bandlängen, die einem Vielfachen der Totstrecke entspre- chen können. Dies betrifft vor allem die Betriebszustände während der innenstationären Phase, wenn zum Beispiel nach dem Einfädeln eines neuen Bandes Einregelvorgänge beim Biegegerüst vorgenommen werden müssen, bis die optimale Bandplanheit eingestellt ist.The installation of the measuring roller in front of the take-up drum also leads to the band areas, which were deformed in the bending stand, are considerably time and Läge¬ offset over the measuring roller. This so-called dead zone, which can take up to 20 m, depending on the system configuration, leads to devalued strip lengths, which can correspond to a multiple of the dead zone. This especially concerns the operating conditions during the in-home stationary phase, when, for example, after the threading of a new band, adjustment operations must be carried out on the bending stand until the optimum strip flatness has been set.
Vor diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, eine Vor¬ richtung zum Erfassen der Bandplanheit in Bandbehandlungsanlagen vorzu¬ schlagen, die die Totstrecke reduziert, die Einregelzeit verkürzt, die Proze߬ geschwindigkeit erhöht und eine Beeinflussung des zu messenden Bands während der Messung vermeidet. Diese Aufgabe wird durch den Gegenstand des Anspruchs 1 gelöst. Vorteil¬ hafte Ausgestaltungen sind in den Unteransprüchen angegeben.Against this background, the object of the invention is to propose a device for detecting strip flatness in strip processing plants, which reduces the dead distance, shortens the settling time, increases the speed of the process and avoids influencing the strip to be measured during the measurement. This object is solved by the subject matter of claim 1. Advantageous embodiments are specified in the subclaims.
Die Erfindung geht von dem Grundgedanken aus, die für die Einstellung des gewünschten Bandzugs ohnehin vorgesehene Spannrolle als Meßrolle aus¬ zubilden. Hierfür ist die erfindungsgemäße Spannrolle für eine Bandbehand¬ lungsanlage mit mindestens einem am Umfang der Spannrolle angeordneten Meßsensor zur Erfassung der Spannung im Band ausgestattet. In der Regel sind mehrere Meßsensoren vorgesehen, um die Spannungsverteilung im Band zu messen.The invention is based on the basic idea of designing the tensioning roller, which is provided anyway for setting the desired strip tensioner, as a measuring roller. For this purpose, the tensioning roller according to the invention for a belt treatment plant is equipped with at least one measuring sensor arranged on the circumference of the tensioning roller for detecting the tension in the belt. As a rule, several measuring sensors are provided to measure the stress distribution in the belt.
Dabei kann der Meßsensor in zum Außenumfang der Rolle offenen Ausneh¬ mungen angeordnet sein. Alternativ kann der Meßsensor in der Nähe des Außenumfangs der Spannrolle derart angeordnet sein, daß die in Radial¬ richtung wirkende Umlenkkraft des Bandes durch die zwischen Meßsensor und Außenumfang verbleibende Materialschicht der Spannrolle auf den Meßsensor wirkt. Als Meßsensoren können insbesondere piezoelektrische Kraftgeber, Dehnungsmeßstreifen oder sogenannte Preßduktoren eingesetzt werden. Preßduktoren wurden von der Firma ABB ca. 1953 entwickelt und basieren auf dem magnetoelastischem Effekt.In this case, the measuring sensor can be arranged in recesses which are open towards the outer circumference of the roller. Alternatively, the measuring sensor may be arranged in the vicinity of the outer circumference of the tensioning roller such that the deflecting force of the belt acting in the radial direction acts on the measuring sensor by the material layer of the tensioning roller remaining between the measuring sensor and the outer circumference. As measuring sensors in particular piezoelectric force transmitter, strain gauges or so-called Preßduktoren can be used. Preßduktoren were developed by the company ABB about 1953 and are based on the magnetoelastic effect.
Eine Spannrolle zeichnet sich dadurch aus, daß sie, beispielsweise durch einen motorischen Antrieb, ihre Oberflächebeschaffenheit und/oder ihre La- gerung, dazu ausgelegt ist, beispielsweise durch Reibungskräfte auf das Band einzuwirken und den über sie geleiteten Bandabschnitt je nach Wir¬ krichtung zu beschleunigen oder zu verlangsamen.A tension roller is characterized in that it is designed, for example by a motor drive, its surface condition and / or its storage, to act, for example, by frictional forces on the belt and to accelerate the belt section guided over it, depending on the direction of action or to slow down.
Die Meßsensoren können in einer Reihe in Richtung der Spannrollenlängs- achse angeordnet sein. Hierdurch wird durch die Meßsensoren der Span¬ nungszustand im Band in der gleichen Bandlängenposition gemessen. Da¬ durch kann die Planheit des Bandes an dieser Bandlängenposition ermittelt werden. Alternative Anordnungen der Meßsensoren sind beispielsweise eine schraubenlinienförmige Anordnung auf dem Umfang der Spannrolle. Die Spannrolle ist insbesondere bevorzugt beschichtet, besonders bevorzugt mit Gummi oder Polyurethan. Durch die Beschichtung lassen sich Reibkräfte zur Erzeugung des gewünschten Bandzugs besonders gut auf das Band übertragen. Die Beschichtung ist dabei vorzugsweise derart ausgeführt, daß sie auch den Meßsensor überdeckt, also beispielsweise auch einen auf dem Außenumfang der Rolle angeordneten Dehnungsmeßstreifen überdeckt.The measuring sensors can be arranged in a row in the direction of the tension roller longitudinal axis. As a result, the voltage state in the strip in the same strip length position is measured by the measuring sensors. As a result, the flatness of the strip at this strip length position can be determined. Alternative arrangements of the measuring sensors are, for example, a helical arrangement on the circumference of the tensioning roller. The tensioning roller is particularly preferably coated, particularly preferably with rubber or polyurethane. Due to the coating, frictional forces for generating the desired strip tension can be transferred particularly well to the strip. The coating is preferably designed such that it also covers the measuring sensor, so for example, also covers a arranged on the outer circumference of the roll strain gauges.
Vorzugsweise weist die Spannrolle einen Durchmesser auf, der sich aus der Beziehung hmax / Droiie < Fließgrenze / E-Modul ergibt, wobei hmax die maxi¬ male Dicke des Bands, Drone der Spannrollendurchmesser, Fließgrenze die Fließgrenzen des Bandmaterials und E-Modul das E-Modul des Bandmateri¬ als ist. Durch diesen großen Rollendurchmesser wird die Einleitung von Bandformfehlern, wie beispielsweise Längs- und Querbogen, in das Band vermieden.Preferably, the tension roller has a diameter which results from the relationship h max / D ro ii e <yield point / modulus of elasticity, where h max is the maximum thickness of the strip, D ro n e the tension roller diameter, yield point the yield point of the Band material and modulus of elasticity of the E-modulus of Bandmateri¬ as is. This large roll diameter avoids the introduction of ribbon form errors, such as longitudinal and transverse bends, into the strip.
Insbesondere zur Gewichtsreduktion kann die Spannrolle als Hohlwelle aus¬ gebildet sein. Durch diese Ausbildung wird ferner der Zugang zu den Me߬ sensoren vereinfacht.In particular for weight reduction, the tensioning roller can be formed as a hollow shaft. This design further simplifies access to the measuring sensors.

Insbesondere kann ein Meßsensor ein Kraftmeßgeber mit einer Abdeckun¬ gen sein, die im Betriebszustand mit ihrer Oberfläche unmittelbar an der Oberfläche des zu prüfenden Bands anliegt. Die Abdeckung ist vorzugweise ohne Wandberührung ausschließlich in einer Ausnehmung, in der der Kraft¬ meßgeber angeordnet ist, in Richtung auf die Achse der Meßrolle verschieb¬ bar. Die Abdeckung kann von der Umlenkkraft des Bandes beaufschlagt sein, und die beiden einander gegenüberliegenden Stirnflächen des Kraft- meßgebers werden belastet, indem von beiden die eine Stirnfläche auf der Aufstandsfläche der Ausnehmung aufgespannt ist, während die andere der Beauschlagung mit der Umlenkkraft über die Abdeckung ausgesetzt ist.In particular, a measuring sensor can be a force measuring transducer with a cover which, in the operating state, bears with its surface directly against the surface of the strip to be tested. The cover is preferably without wall contact only in a recess in which the Kraft¬ measuring sensor is arranged in the direction of the axis of the measuring roller verschieb¬ bar. The cover may be acted upon by the deflection force of the band, and the two opposite end faces of the force Measuring sensors are loaded by both of the one end face is clamped on the footprint of the recess, while the other is exposed to the Beauschelagung with the deflection force on the cover.

Erfindungsgemäß kann eine erfindungsgemäße Spannrolle zum Messen der Veränderung des Bandzugs vom Einlauf des Bandes auf die Spannrolle zum Auslauf des Bandes von der Spannrolle verwendet werden. Auf diese Weise können Ergebnisse über den Bandzugsaufbau über die Spannrolle ermittelt werden.According to the invention, a tensioning roller according to the invention for measuring the change of the strip tension from the inlet of the strip to the tensioning roller to the outlet of the strip from the tensioning roller can be used.
