Beschreibungdescription
Titel: Wickelwelle zum Aufwickeln bandförmiger MaterialienTitle: Winding shaft for winding band-shaped materials
Die Erfindung betrifft eine Wickelwelle zum Aufwickeln bandförmiger Materialien, insbesondere für Rollenschneid- und Wickelmaschinen zum Längsteilen von vornehmlich dünnem Walzband aus Metall und Stahl in Einzelbänder und Aufwickeln der Ξinzelbänder zu Bandrollen, mit einermotorisch antreibbaren Kernwelle, Spannelementen zum Befestigen der auf die und von der Wickelwelle aufschiebbaren und abziehbaren Wickelhülsen für die Bandrollen sowie Bauelementen zum Übertragen des Drehmomentes der Kernwelle auf die einzelnen Wickelhülsen beim Aufwickeln der Einzelbänder mit gleichem oder annährend gleichem Bandzug.The invention relates to a winding shaft for winding band-shaped materials, in particular for reel cutting and winding machines for slitting mainly thin metal and steel strip into individual strips and winding the individual strips into reels, with a motor-driven core shaft, tensioning elements for attaching to and from the winding shaft Slip-on and peel-off winding sleeves for the tape rolls and components for transmitting the torque of the core shaft to the individual winding sleeves when winding up the individual tapes with the same or approximately the same tape tension.
Das Aufwickeln der durch Längsteilen eines Walzbandes erhaltenen Einzelbänder auf Wickelhülsen, die auf einer gemeinsamen Wickelwelle angeordnet sind, bringt Probleme mit sich, die ihren Ursprung in der Beschaffenheit gewalzter Bänder haben. Gewalzte Bänder sind in der Mitte und an den Seiten unterschiedlich dick, wobei meistens die Dicke in der Bandmitte etwas größer ist als im Bereich der beiden Bandkanten. Daher bestehen im Band innere mechanische Spannungen zwischen Bandkanten und Bandmitte. Beim Längsteilen des Walzbandes - mittels einer Rollenschneidmaschine in Einzelbänder werden die inneren Spannungen aufgehoben und es ergeben sich dabei bei relativ dünnen Bändern unterschiedlich lange Teilstreifen bzw. Einzelbänder, d.h., die Einzelbänder, die sich durch das Längsteilen des dickeren Mittelbereiches des Walzbandes ergeben, sind kürzer und die durch das Längsteilen der dünneren Kantenbereiche des Walzbandes entstehenden Einzelstreifen bzw. •Einzelbänder sind länger. Die unterschiedlichen Längen und unterschiedlichen Banddicken der Einzelbänder müssen zum Aufwickeln aller Einzelbänder mit gleichem Bandzug ausgeglichen werden, wenn die Einzelbänder auf Wickelhülsen aufgewickelt werden, die auf einer gemeinsamen Wickelwelle angeordnet sind, und alle Einzelbänder gleichmäßig fest aufgewickelt werden sollen.The winding of the individual strips obtained by longitudinally dividing a rolled strip onto winding tubes which are arranged on a common winding shaft brings with it problems which have their origin in the nature of the rolled strips. Rolled strips are of different thicknesses in the middle and on the sides, whereby the thickness in the middle of the strip is usually somewhat larger than in the area of the two strip edges. Therefore there are internal mechanical tensions in the belt between the belt edges and the belt center. When slitting the rolled strip - by means of a slitter in single strips, the internal tensions are released and there are partial strips or individual strips of different lengths in the case of relatively thin strips, i.e. the individual strips that result from the slitting of the thicker central area of the rolled strip are shorter and by the longitudinal parts of the thinner edge portions of the rolled strip emerging single strip or • individual belts are longer. The different lengths and Different tape thicknesses of the individual tapes must be compensated for winding all individual tapes with the same tape tension, if the individual tapes are wound on winding cores, which are arranged on a common winding shaft, and all individual tapes are to be wound uniformly firmly.
Zum Aufwickeln mehrerer Rollen aus bandförmigen Materialien auf eine aus der EP 0 863 101 A2 bekannte Wickelwelle der gattungsgemäßen Art wird eine mit Friktionselementen bestückte Kernwelle eingesetzt, um die einzelnen Bandrollen kinematisch zu entkoppeln und um definierte Drehmomente aufbringen zu können. Damit soll erreicht werden, daß alle Bandrollen, unabhängig von ihrer jeweiligen Bandbreite, mit spezifisch gleichen Bandzügen belastet werden, um eine Faltenbildung und eine Verspannung innerhalb der Schneidemaschine sowie die Zerstörung einzelner Materialbänder zu vermeiden.For winding several rolls of band-shaped materials onto a winding shaft of the generic type known from EP 0 863 101 A2, a core shaft equipped with friction elements is used in order to kinematically decouple the individual band rolls and to be able to apply defined torques. This is intended to ensure that all tape rolls, regardless of their respective bandwidth, are loaded with specifically the same tape pulls in order to avoid creasing and tensioning within the cutting machine and the destruction of individual material tapes.
Die bekannte Wickelwelle zum Aufwickeln bandförmiger Materialien auf Wickelhülsen besteht aus einer von Friktionselementen in ringförmiger Anordnung umgebenen Kernwelle sowie radial wirkenden Spannelementen, die in Betriebsstellung einen Reibschluß zwischen von der Kernwelle mitgenommenen Reibelementen und den Friktionselementen herstellen, durch den unter Schlupf ein Drehmoment von der Kernwelle auf die Friktionselemente übertragbar ist. Die Friktionselemente sind nach außen beweglich, um im Betrieb eine drehstarre Verbindung zwischen den Friktionselementen und der Wickelhülse herzustellen.The known winding shaft for winding band-shaped materials on winding cores consists of a core shaft surrounded by friction elements in an annular arrangement and radially acting tensioning elements which, in the operating position, produce a frictional connection between friction elements carried by the core shaft and the friction elements, by means of which a torque from the core shaft slips on the friction elements is transferable. The friction elements are movable outwards in order to establish a torsionally rigid connection between the friction elements and the winding tube during operation.
Die Spannelemente bewegen mittels der von ihnen aufgebrachten Radialkräfte über die Reibelemente die Friktionselemente in radialer Richtung nach außen und bringen die Friktionselemente in Anlage an die Wickelhülse, um zuverlässig eine schlupffreie Mitnahme der Wickelhülse mit einem bestimmten Drehmoment zu gewährleisten. Dabei liegt unter den in Betriebsstellung wirkenden Radialkräften der Spannelemente das durch die Reibpaarung Reibelement/Friktionselement übertragene Drehmoment unter dem von der Paarung Friktionselement/ Wickelhülse übertragbaren Drehmoment, so daß zwischen Friktionselement und Wickelhülse eine drehstarre Mitnahme erfolgt.By means of the radial forces they apply, the tensioning elements move the friction elements outward in the radial direction and bring them about the friction elements in contact with the winding tube in order to reliably ensure a slip-free entrainment of the winding tube with a certain torque. Here, under the radial forces acting in the operating position of the clamping elements, the torque transmitted by the friction pairing friction element / friction element is below the torque that can be transmitted by the pairing friction element / winding sleeve, so that a torsionally rigid entrainment takes place between the friction element and the winding sleeve.
Die DE 195 15 723 AI beschreibt eine gattungsgemäße Wickelwelle, die aus einer Kernwelle mit am Umfang verteilt angeordneten Längsnuten besteht, in denen jeweils eine zur Außenseite hin weisende Gleitleiste und ein aufblasbarer Druckmittelschlauch angeordnet sind, um die Gleitleiste radial nach außen zu bewegen. Auf der Kernwelle sitzt ein ringförmiger Grundkörper, an dessen Innenfläche die Gleitleisten zur Anlage kommen. Die sich über die gesamte Länge der Kernwelle erstreckenden Gleitleisten bestehen entweder aus ölgetränkten Filzleisten oder aus einem Gleitmaterial, das Schmierstoff abgeben kann. Auf der Außenseite des Grundkörpers sind über den Umfang verteilt mehrere schräg verlaufende Laufflächen angeordnet, die mit als Kugeln ausgebildeten Spannelementen zusammenwirken. Die Kugeln sind in Ausnehmungen eines Spannrings derart angeordnet, daß sie auch in ungespanntem Zustand der Wickelwelle geringfügig über die Außenfläche des Spannrings hervortrete .DE 195 15 723 AI describes a generic winding shaft, which consists of a core shaft with longitudinal grooves distributed around the circumference, in each of which a sliding bar facing the outside and an inflatable pressure medium hose are arranged to move the sliding bar radially outward. An annular base body sits on the core shaft, on the inner surface of which the slide strips come to rest. The sliding strips, which extend over the entire length of the core shaft, either consist of oil-soaked felt strips or of a sliding material that can release lubricant. On the outside of the base body, several obliquely running treads are arranged distributed over the circumference, which interact with tensioning elements designed as balls. The balls are arranged in recesses of a clamping ring in such a way that they protrude slightly beyond the outer surface of the clamping ring even when the winding shaft is not tensioned.
Zu Beginn eines AufwiekelVorgangs werden die Wickelhülsen auf die Friktionswickelwelle aufgesteckt. Da die Kugeln etwas über die Außenseite des Spannrings vorstehen, lassen sich die Wickelhülsen sehr leicht in axialer Richtung auf die Friktionswickelwelle bis in die jeweils gewünschte bzw. erforderliche Position aufschieben. Vorher sind die einzelnen Druckmittelschlauche aufgeblasen worden, so daß über die Gleitleisten ein Reibschluß zum Grundkörper hin erfolgt und sich dieser zusammen mit der Drehbewegung der Kernwelle entsprechend im Uhrzeigersinn mitdreht. Dadurch werden die Kugeln aufgrund der Schräglage der Laufflächen weiter nach außen gedrückt, wodurch schließlich die Wickelhülsen fest in ihrer eingenommenen Lage gehalten werden. Im entspannten Zustand der Friktion nehmen die Kugeln wieder ihre ursprüngliche Lage ein, in der sie geringfügig über die Außenfläche des Spannrings hervorstehen, so daß die fertig gewickelten Bandrollen leicht von der Wickelwelle abgezogen werden können.At the beginning of a winding process, the winding cores are placed on the friction winding shaft. Since the balls protrude slightly beyond the outside of the clamping ring, the winding cores can be easily moved in the axial direction onto the friction winding shaft up to the desired or Postpone required position. The individual pressure medium hoses have been inflated beforehand so that there is a frictional connection to the base body via the slide strips and this rotates clockwise along with the rotary movement of the core shaft. As a result, the balls are pressed further outwards due to the inclined position of the running surfaces, as a result of which the winding sleeves are finally held firmly in their assumed position. In the relaxed state of the friction, the balls return to their original position, in which they protrude slightly beyond the outer surface of the tensioning ring, so that the completely wound tape rolls can be easily removed from the winding shaft.
Bei den bekannten Friktionswickelwellen ist es schwierig, insbesondere bei kleinen Bandrollendurchmessern ein großes Drehmoment von der Kernwelle auf die Wickelhülsen der einzelnen Bandrollen zu übertragen und mit einem konstanten Bandzug ein gleichmäßiges Aufwickeln der einzelnen Materialbänder zu erreichen.In the known friction winding shafts, it is difficult to transmit a large torque from the core shaft to the winding cores of the individual band reels, in particular in the case of small band reel diameters, and to achieve a uniform winding of the individual material bands with a constant band tension.
Der Erfindung liegt die Aufgabe zugrunde, eine Wickelwelle der gattungsgemäßen Art zu schaffen, die ein gleichmäßiges Aufwickeln von Bandrollen mit unterschiedlichen Durchmessern und Rollenbreiten ermöglicht.The invention has for its object to provide a winding shaft of the generic type that enables a uniform winding of tape rolls with different diameters and roll widths.
Diese Aufgabe ist erfindungsgemäß gelöst durch eine Wickelwelle zum Aufwickeln bandförmiger Materialien mit den Merkmalen des Patentanspruchs 1.According to the invention, this object is achieved by a winding shaft for winding strip-shaped materials with the features of patent claim 1.
Die Unteransprüche beinhalten vorteilhafte und zweckmäßige Weiterbildungen der Erfindung. Die neue Wickelwelle stellt eine optimale Lösung der der Erfindung zugrunde liegenden Aufgabenstellung dar.The subclaims contain advantageous and expedient developments of the invention. The new winding shaft represents an optimal solution to the problem underlying the invention.
Die Erfindung ist nachstehend anhand schematischer Zeichnungsfiguren erläutert, die folgendes darstellen:The invention is explained below on the basis of schematic drawing figures, which represent the following:

Fig. 2 einen Querschnitt der Wickelwelle nach Linie II - II der Figur 1.2 shows a cross section of the winding shaft according to line II - II of FIG. 1.
Die Wickelwelle 1 nach den Figuren 1 und 2 zum Aufwickeln von Einzelbändern 2 für eine nicht dargestellte Rollenschneid- und Wickelmaschine zum Längsteilen von dünnem Walzband aus Metall in Einzelbänder und Aufwickeln der Einzelbänder zu Bandrollen 3 weist eine motorisch antreibbare Kernwelle 4 mit einer in Richtung der Wellenachse 5-5 verlaufenden, durchgehenden Abflachung 6 auf, in der eine über die Länge der Kernwelle 4 verlaufende zylindrische Nut 7 als Lager für nebeneinander liegende Ritzel 8 mit einer Außenverzahnung 9 ausgebildet ist. Der Umfangswinkel der Nut 7 der Kernwelle 4 ist um einige Grad größer als 180°, und der Umfangswinkel des Außenumfangs der Kernwelle 4 ist wesentlich größer als 180°.The winding shaft 1 according to FIGS. 1 and 2 for winding up individual strips 2 for a reel cutting and winding machine (not shown) for dividing thin rolled metal strips into individual strips and winding up the individual strips into strip rolls 3 has a motor-driven core shaft 4 with one in the direction of the shaft axis 5-5 running, continuous flattening 6, in which a cylindrical groove 7 running over the length of the core shaft 4 is designed as a bearing for adjacent pinions 8 with external teeth 9. The circumferential angle of the groove 7 of the core shaft 4 is a few degrees larger than 180 °, and the circumferential angle of the outer circumference of the core shaft 4 is substantially larger than 180 °.
Auf der Kernwelle 4 sind Zahnkränze • 10 mit einer Innenverzahnung 11 drehbar gelagert, die mit der Außenverzahnung 9 der den einzelnen Zahnkränzen 10 zugeordneten Ritzel 8 in eingriff steht.On the core shaft 4, sprockets • 10 are rotatably supported with an internal toothing 11, which meshes with the external toothing 9 of the pinions 8 assigned to the individual toothed rings 10.
Die Ritzel 8 und die Zahnkränze 10, die jeweils in Reihe nebeneinander in bzw. auf der Kernwelle 4 drehbar gelagert sind, sind jeweils flüssigkeitsdicht gegeneinander und gegen die beiden Enden der Kernwelle (4) flüssigkeitsdicht abgedichtet. Auf diese Weise bildet die Kernwelle 4 mit den Zahnkränzen 10 eine geschlossene Hydraulikkammer 12, die über nicht dargestellte Kanäle in der Kernwelle sowie eine Zuleitung zum Auffüllen mit Öl und zum Zuführen von Kühlöl an einen Ölbehälter mit einer Ölpumpe angeschlossen ist.The pinions 8 and the sprockets 10, which are each rotatably mounted in series next to one another in or on the core shaft 4, are each liquid-tight against one another and against the both ends of the core shaft (4) sealed liquid-tight. In this way, the core shaft 4 with the ring gears 10 forms a closed hydraulic chamber 12 which is connected via channels (not shown) in the core shaft and a feed line for filling with oil and for supplying cooling oil to an oil container with an oil pump.
Durch die nebeneinander angeordneten Ritzel 8 wird die Hydraulikkammer 12 in zwei Kammern 12a, 12b aufgeteilt.The hydraulic chamber 12 is divided into two chambers 12a, 12b by the pinions 8 arranged side by side.
Die beiden Kammern 12a, 12b der Hydraulikkammer 12 und die Zahnlücken 14 zwischen den Zähnen 13 der Zahnkränze 10 sind mit Öl 15 gefüllt.The two chambers 12a, 12b of the hydraulic chamber 12 and the tooth gaps 14 between the teeth 13 of the ring gears 10 are filled with oil 15.
Auf dem Außenumfang der Zahnkränze 10 sind nicht dargestellte Spannelemente zum Aufspannen von Wickelhülse 16 zum Aufwickeln der Einzelbänder 2 angeordnet. Beim Aufwickeln von Einzelbändern 2 mit gleicher Bandbreite weisen die Wickelhülsen 16 eine der Bandbreite angepraßte gleiche Wickelbreite auf. Zum Aufwickeln von Ξinzelbändern 2 mit unterschiedlicher Bandbreite werden entsprechende Wickelhülsen 16 mit unterschiedlicher Wickelbreite eingesetzt. Je nach Wickelbreite werden die Wickelhülsen 16 auf einen oder mehrere Zahnkränze 10 der Wickelwelle 1 aufgespannt.On the outer circumference of the sprockets 10, clamping elements (not shown) for clamping the winding tube 16 for winding the individual strips 2 are arranged. When winding individual tapes 2 with the same bandwidth, the winding sleeves 16 have the same winding width that is matched to the tape width. Corresponding winding cores 16 with different winding widths are used to wind up individual strips 2 with different widths. Depending on the winding width, the winding sleeves 16 are clamped onto one or more sprockets 10 of the winding shaft 1.
Die Betriebsweise der Wickelrolle ist folgende: Zu Beginn eines AufwiekelVorgangs, bei dem mehrere Einzelbänder 2 auf nebeneinander auf die Kernwelle 4 einer Wickelwelle 1 aufgespannte Wickelhülsen 16 zu Bandrollen 3 aufgewickelt werden, wird durch die sich im Gegenuhrzeigersinn a angetriebene Kernwelle 4, deren Drehzahl vom Wert Null auf die Betriebsdrehzahl hochgefahren wird, ein an den Einzelbändern 2 angreifender Bandzug B aufgebaut, dem ein Rückhaltezug R entgegen der Bandlaufrichtung c entgegenwirkt. Durch die in Drehrichtung a angetriebene Kernwelle 4 und den über die Wickelhülsen 16 an den .einzelnen Zahnkränzen 10 angreifende Rückhaltezug R werden die mit den Zahnkränzen 10 im Eingriff stehenden Ritzel 8 im Uhrzeigersinn b in Drehung versetzt und die sich drehenden Ritzel 8 fördern Öl 15 aus der Kammer 12a in die Kammer 12b der Hydraulikkammer 12, so daß in der Kammer 12b ein Öldruck aufgebaut wird. Durch den Öldruck in den Kammern 12b wirkt über die Zahnflanken 17 der Zähne 13 eine Druckkraft K auf die einzelnen Zahnkränze 10.The mode of operation of the winding roll is as follows: At the beginning of a winding process, in which a plurality of individual tapes 2 are wound onto tape cores 4, which are spanned side by side on the core shaft 4 of a winding shaft 1, the core shaft 4, which is driven in the counterclockwise direction a, reveals its speed of value Is brought up to zero to the operating speed, a belt pull B acting on the individual belts 2 is set up, which a restraint pull R counteracts the tape running direction c. Due to the core shaft 4 driven in the direction of rotation a and the retention pull R engaging the individual sprockets 10 via the winding sleeves 16, the pinions 8 engaged with the sprockets 10 are rotated clockwise b and the rotating pinions 8 deliver oil 15 the chamber 12a into the chamber 12b of the hydraulic chamber 12, so that an oil pressure is built up in the chamber 12b. Due to the oil pressure in the chambers 12b, a pressure force K acts on the individual toothed rings 10 via the tooth flanks 17 of the teeth 13.
Nach Beendigung der Anlaufphase werden die Einzelbänder 2 durch die mit einer konstanten Betriebsdrehzahl rotierende Kernwelle 4 mit einem konstanten Bandzug B auf die einzelnen Wickelhülsen 16 der Wickelwelle 1 zu Bandrollen 3 aufgewickelt, wobei sich ein Gleichgewicht zwischen der auf die einzelnen Zahnkränze 10 aufgrund des Öldrucks in der Kammer 12b wirkenden Druckkraft K und dem Rückhaltezug R einstellt, so dass die Zahnkränze 10 synchron mit der Kernwelle 4 rotieren.After the start-up phase, the individual tapes 2 are wound by the core shaft 4 rotating at a constant operating speed with a constant tape tension B onto the individual winding tubes 16 of the winding shaft 1 to form tape rolls 3, with a balance between that on the individual sprockets 10 due to the oil pressure in the pressure force K acting in the chamber 12b and the restraining cable R so that the ring gears 10 rotate synchronously with the core shaft 4.
Lassen Bandzug B und Rückhaltezug R an einem oder mehreren der Zahnkränze 10 aufgrund einer geringeren Banddicke eines oder mehrerer Einzelbänder 2 gegenüber den anderen Ξinzelbändern mit der Folge eines kleineren Wickeldurchmessers der entsprechenden Bandrolle oder Bandrollen 3 im Vergleich zu den anderen Bandrollen nach, wird bzw. werden dieser Zahnkranz bzw. diese Zahnkränze 10 aufgrund der in der Kammer 12b nachlassenden Druckkraft K kurzzeitig in eine voreilende Drehbewegung in Pfeilrichtung a relativ zur Kernwelle 4 versetzt, so daß das bzw. die Ritzel 8 entgegen dem Uhrzeigersinn dreht bzw. drehen, bis die Druckkraft K durch den Öldruck in dem benachbarten Raum der Kammer 12b wieder aufgebaut und ausgeglichen ist. Es stellen sich ein erneutes Gleichgewicht zwischen der Druckkraft K und der Rückhaltekraft R an dem bzw. den entsprechenden Zahnkränzen 10 und ein konstanter Bandzug B an " der bzw. den zugehörigen Bandrollen 3 ein. Dieser Vorgang erfolgt im Betrieb kontinuierlich und stufenlos .If the band tension B and the retention tension R on one or more of the sprockets 10 decrease due to a smaller band thickness of one or more individual bands 2 compared to the other individual bands, with the consequence of a smaller winding diameter of the corresponding band reel or band reels 3 compared to the other band reels this sprocket or sprockets 10 due to the decreasing in the chamber 12b compressive force K briefly in a leading rotational movement in the direction of arrow a relative to the core shaft 4, so that the pinion or 8 rotates counterclockwise or until the pressure force K is rebuilt and balanced by the oil pressure in the adjacent chamber 12b. A new equilibrium is established between the compressive force K and the restraining force R on the corresponding toothed ring or rings 10 and a constant band tension B on the associated band reel or rolls 3. This operation takes place continuously and continuously during operation.
Je nach Bandzug B an den Bandrollen 3 der Einzelbänder 2, der sich aufgrund von Banddickenunterschieden der Einzelbänder ändert, können sich automatisch unterschiedliche Relativgeschwindigkeiten der Zahnkränze 10 der Wickelwelle 1 einstellen.Depending on the tape tension B on the tape rolls 3 of the individual tapes 2, which changes due to differences in tape thickness of the individual tapes, different relative speeds of the toothed rings 10 of the winding shaft 1 can be set automatically.
Das Kühlöl wird zweckmäßig in einem Kühlkreislauf mittels einer druckgeregelten Pumpe über die drucklose Kammer 12a in die Druckkammer 12b geleitet.The cooling oil is expediently conducted in a cooling circuit by means of a pressure-controlled pump via the unpressurized chamber 12a into the pressure chamber 12b.
Bei einer abgeänderten Ausführungsform der Wickelwelle können die Ritzel 8 auf einer zusätzlichen Welle drehbar gelagert sein.In a modified embodiment of the winding shaft, the pinion 8 can be rotatably mounted on an additional shaft.
Ferner können die Spannelemente für die Spannelemente für die Wickelhülsen 16 durch das Drucköl in der Kammer 12b der Hydraulikkammer 12 betätigt werden. Furthermore, the clamping elements for the clamping elements for the winding sleeves 16 can be actuated by the pressure oil in the chamber 12b of the hydraulic chamber 12.
