Abstract

The device aligns the end of a steel cord band fed off from a supply reel for splicing with the end of the steel cord band from the preceding supply reel via reversible drives (20) coupled to suction or magnetic rollers (11,12), positioned transverse to the feed direction of the steel cord band, for seizing the end of the steel cord band hanging down.

Description

Die Erfindung bezieht sich auf eine Vorrichtung zum automatischen Ausrichten des vorlaufenden Anfangsabschnittes eines von einer Vorratsrolle abgewickelten Cordbandes, insbesondere eines Stahlcordbandes, zum Anspleißen an das nachlaufende Ende des Cordbandes der vorherigen Vorratsrolle.The invention relates to a device for automatic alignment of the leading beginning section of one unwound from a supply roll Cord tape, especially a steel cord tape, for splicing on the trailing end of the cord band of the previous supply roll.

Beim Wechsel von einer Cordbandrolle zur nächsten Cordbandrolle muss das Ende der abgelaufenen Rolle an den Anfangsabschnitt der neuen Cordbandrolle angespleißt werden. Hierzu ist es bisher üblich, dass das Material vom Bediener manuell an eine Magnetleiste im Bereich der Spleißleiste - gegebenenfalls ist die Spleißleiste selbst als Magnetleiste ausgebildet - angelegt wird, wobei durch das schräge Abschneiden der Bandenden und das Durchhängen sowie das Sich-Verziehen des ja sehr weichen unvulkanisierten Cordbandes beim Ausrichten Spannungen und Verformungen auftreten, sodass nach dem Aneinanderspleißen große Abschnitte als unbrauchbar wieder herausgeschnitten werden müssen. Dies unterbricht nicht nur den Fertigungsprozess, sondern ist wegen des hohen Abfallanteils auch sehr teuer.When changing from one cord reel to the next cord reel, the end must of the expired roll spliced onto the start section of the new cord band roll become. So far it has been customary for the material to be removed by the operator manually on a magnetic strip in the area of the splice strip - if necessary, the Splice bar itself designed as a magnetic bar - is created, whereby by the sloping cutting of the tape ends and sagging and warping of the very soft unvulcanized cord tape when aligning Tensions and deformations occur so that after splicing large sections have to be cut out as unusable. This not only interrupts the manufacturing process, but is due to the high proportion of waste also very expensive.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung zum automatischen Ausrichten des Materials vor dem Anspleißen zu schaffen, das ein schonendes Ausrichten ermöglicht, sodass letztendlich lediglich die eigentliche Spleißstelle herausgeschnitten werden muss und praktisch kein sonstiger Abfall auftritt.The invention is therefore based on the object of a device for automatic Aligning the material before splicing to create a gentle Alignment allows, so that ultimately only the actual splice must be cut out and practically no other waste occurs.

Zur Lösung dieser Aufgabe ist eine solche Vorrichtung erfindungsgemäß gekennzeichnet durch mit reversierbaren Antriebseinrichtungen versehene Saug- oder Magnetrollen zum anhaftenden Befestigen des nach unten durchhängenden Anfangsabschnittes des Cordbandes, wobei bevorzugt zwei parallel übereinander angeordnete Saug- oder Magnetrollen vorgesehen sind und vor der unteren Saugoder Magnetrolle wenigstens eine axial nach beiden Seiten gegen Federn verschiebbar gelagerte Umlenkrolle angeordnet ist. To achieve this object, such a device is characterized according to the invention by suction or provided with reversible drive devices Magnetic rollers for the adhesive attachment of the sagging start section the cord band, preferably two parallel one above the other arranged suction or magnetic rollers are provided and in front of the lower suction or Magnetic roller at least one axially displaceable against springs on both sides mounted deflection roller is arranged.

Durch die erfindungsgemäße Anordnung wird erreicht, dass beim Spannen des Cordbandes beim Anlaufen der Saug- oder Magnetrollen, an die das vorlaufende Anfangsende der neuen Vorratsrolle außermittig und gegebenenfalls auch noch schräg geneigt angesetzt worden ist, durch die unterschiedliche Zugwirkung an beiden Seitenkanten des Bandes beim Straffen quer zur Laufrichtung gerichtete Kraftkomponenten auftreten, die das Band aus seiner außermittig versetzten Stellung nach innen gleiten lassen.The arrangement according to the invention ensures that when the Cordbandes when the suction or magnetic rollers start, to which the leading one Beginning of the new supply roll off-center and possibly also has been set at an incline due to the different pulling action both side edges of the tape when tightening directed transversely to the running direction Force components occur that move the belt off-center Let the position slide inwards.

Bevorzugt eignet sich die erfindungsgemäße Anordnung, obgleich sie auch für Saugrollen und Textilcordbänder denkbar ist, für Stahlcordbänder mit Magnetrollen für die Ausrichtvorrichtung, da diese Magnetrollen außerordentlich glatt ausgebildet sein können, sodass die beim Spannen auftretenden Querkraftkomponenten das weiche Stahlcordband ohne die Gefahr von Verformungen in die Mittelstellung gleiten lassen.The arrangement according to the invention is preferably suitable, although it is also suitable for Suction rolls and textile cord tapes are conceivable for steel cord tapes with magnetic rolls for the alignment device, since these magnetic rollers are extremely smooth can be so that the shear force components that occur during clamping the soft steel cord tape without the risk of deformation in the middle position slide.

Um Blockierungen zu vermeiden, kann dabei in Ausgestaltung der Erfindung vorgesehen sein, dass nach einem Spannen des Stahlcordbandes und einer gewissen Seitenverschiebung des schräg aufgesetzten Cordbandendes die Ausrichtvorrichtung angehalten und automatisch reversiert wird, das heißt, ein Stückchen in die Gegenrichtung läuft, sodass das Band zunächst wieder durchhängt, ohne an den Umlenkrollen anzuliegen. Der Ruck beim Wieder-Spannen durch das Anlegen an die Umlenkrollen ist nämlich der Zeitpunkt, bei dem die seitliche Verrutschbewegung des noch außermittig sitzenden Cordbandes am Besten funktioniert. Diese Mehrfachbetätigung kann automatisch einprogrammiert sein, sodass beispielsweise bei jedem Ausrichten grundsätzlich sechs Mal angespannt und wieder reversiert wird, um das von der Vorratsrolle abgezogene Cordbandende in sechs aufeinanderfolgenden Schritten in die Mittelstellung auszurichten.In order to avoid blockages, an embodiment of the invention can be provided be that after tensioning the steel cord and a certain Lateral shift of the obliquely placed cord band end the alignment device stopped and reversed automatically, that is, a bit in the opposite direction runs, so that the tape sags again without starting to rest the pulleys. The jerk when tightening again by putting on at the pulleys is the time at which the lateral sliding movement of the cord tape that is still off-center works best. This Multiple actuation can be programmed automatically, for example tense and reversed six times with each alignment the cord strip end that has been pulled off the supply roll in six successive steps in the middle position.

Selbstverständlich wird bei dem Ausrichten das Band nur um größenordnungsmäßig 20 cm, also das Ausmaß des Durchhängens des von der Vorratsrolle abgezogenen Abschnitts mithilfe der Saug- oder Magnetrollen in Längsrichtung bewegt, da ja nach dem Straffen im Anschluss an das Sich-anlegen an die Umlenkrollen das Bandende an den Saug- oder Magnetrollen sowohl in Förderrichtung als auch quer dazu abrutscht. Wichtig für die erfindungsgemäße Ausrichtung ist die Querverrutschung, die automatisch zu einer Verschiebung in die gewünschte Mittelstellung führt.Of course, when aligning the tape is only of the order of magnitude 20 cm, i.e. the amount of sagging of the pulled off the supply roll Section moved longitudinally using the suction or magnetic rollers, since yes after tightening after putting on the pulleys the belt end on the suction or magnetic rollers both in the conveying direction and slips across. Cross-slipping is important for the alignment according to the invention, that automatically move to the desired center position leads.

Die axiale, nach beiden Seiten gegen Federn gegebene Verschiebemöglichkeit der Umlenkrolle ist wichtig, da ansonsten die Reibungskraft des Cordbandes an der Umlenkrolle die seitliche Verschiebung des Cordbandendes durch die Querkraftkomponenten an den Saug- oder Magnetrollen blockieren oder zumindest behindern würde. Nach jedem Ausrichtschritt bringen die seitlichen Federn die Umlenkrollen in die mittige Ausgangslange zurück, was noch dadurch begünstigt wird, dass ja nach den einzelnen Ausrichtschritten die Antriebsvorrichtung für die Saug- oder Magnetrollen reversiert und damit das Cordband ja wieder stärker durchhängt und somit nicht mehr oder nur mit sehr geringer Anlagekraft an den Umlenkrollen noch anliegt.The axial possibility of displacement against springs on both sides the pulley is important, otherwise the frictional force of the cord band the deflection roller the lateral displacement of the cord end by the shear force components block on the suction or magnetic rollers or at least would hinder. The side springs bring the after every alignment step Deflection pulleys back into the central exit length, which also favors this is that, depending on the individual alignment steps, the drive device for the Suction or magnetic rollers are reversed, making the cord strap stronger again slack and therefore no longer or only with very little investment power to the Deflection pulleys are still present.

Bei Verwendung der bei Stahlcordbändern bevorzugt verwendeten Magnetrollen, sollen diese abwechselnd aus magnetischen und unmagnetischen Scheiben geschichtet sein.When using the magnetic rollers preferred for steel cord tapes, these should alternately be layered from magnetic and non-magnetic disks his.

Die Spleißleiste zur Verbindung des Endes der abgelaufenen Cordbandrolle mit dem Anfangsabschnitt der neuen Cordband-Vorratsrolle kann bevorzugt parallel zur den Magnetrollen zwischen diesen angeordnet sein, wobei Sensoren zur Erfassung der Bandendkanten der zu verbindenden Stahlcordbänder die Funktion steuern können.The splice bar for connecting the end of the expired cord roll with the beginning section of the new cord tape supply roll can preferably be parallel to be arranged between the magnetic rollers, with sensors for detection the band end edges of the steel cord bands to be connected can control.

Bei 1 erkennt man eine Cordband-Vorratsrolle, deren Endabschnitt 2 mit dem abgelaufenen Endabschnitt 3 der vorherigen Cordbandrolle verspleißt werden soll. Um dieses Verspleißen ohne große Verspannungen und Versetzungen durchführen zu können, ist erfindungsgemäß eine automatische Ausrichtvorrichtung 4 vorgesehen, die das Ausrichten des vorlaufenden Anfangsabschnittes 2 des Cordbandes 5 von der neuen Vorratsrolle 1 übernimmt. Bei 6 erkennt man eine Mitläuferrolle zum Aufwickeln des Trennbandes 7 zwischen den einzelnen klebrigen Cordbandlagen. 8 und 9 sind die Abzugsrollen der anschließenden Verarbeitungsstation für das Cordband und 10 zeigt eine Tänzerrolle.At 1 you can see a cord tape supply roll, the end section 2 with the expired End section 3 of the previous cord roll is to be spliced. To carry out this splicing without great tension and dislocation To be able to, an automatic alignment device 4 is provided according to the invention, the alignment of the leading start section 2 of the cord band 5 takes over from the new supply roll 1. At 6 you can see a follower role to wind up the separating tape 7 between the individual sticky ones Cordbandlagen. 8 and 9 are the take-off rolls of the subsequent processing station for the cord band and 10 shows a dancer role.

Die erfindungsgemäße Vorrichtung umfasst - im dargestellten Ausführungsbeispiel soll das Cordband 5 ein Stahlcordband sein - zwei Magnetrollen 11 und 12, die in Abstand übereinander angeordnet sind, wobei zwischen ihnen die Gegenleiste 13 für die Spleißleiste 14 angeordnet ist. Diese Magnetrollen bestehen abwechselnd aus magnetischen und nichtmagnetischen Scheiben und ermöglichen ein Anheften des Cordbandendes 2 durch einfaches Andrücken. Unterhalb der unteren Magnetrolle 11 ist eine Umlenkrolle 15 angeordnet, wobei für Fälle einer anderen Zuführung von der Vorratsrolle 1 noch eine weitere Umlenkrolle 16 vorhanden ist, die, wie man insbesondere aus Fig. 1b erkennen kann, als Hohlwalze auf einer Welle 17 beidseits gegen Federn 18, 19 axial verschiebbar gelagert ist. Bei 20 ist der Antriebsmotor zum Antreiben der Magnetrollen 11 und 12 angedeutet.The device according to the invention comprises - in the illustrated embodiment the cord band 5 should be a steel cord band - two magnetic rollers 11 and 12, which are spaced one above the other, with the counter bar between them 13 is arranged for the splice bar 14. These magnetic rollers alternate from magnetic and non-magnetic disks and enable tacking the cord end 2 by simply pressing it on. Below the Lower magnetic roller 11, a deflection roller 15 is arranged, one for cases another feed from the supply roll 1 there is a further deflection roller 16 is, as can be seen in particular from Fig. 1b, as a hollow roller is axially displaceably mounted on a shaft 17 on both sides against springs 18, 19. At 20, the drive motor for driving the magnetic rollers 11 and 12 is indicated.

Nachdem ein Bediener den Endabschnitt 2 des Stahlcordbandes 5 wie in Fig. 1b versetzt und seitlich verschoben an die Magnetrollen 11 und 12 angeheftet hat, werden diese in Rotation versetzt und spannen dabei das Stahlcordband in die Stellung nach den Figuren 2a und 2b. Dabei strafft sich bei schief angebrachtem Bandende 2 die eine Seite eher als die andere. Hierdurch wird eine seitliche Kraft auf das Bandende 2 erzeugt, die dieses in Richtung Mittelachse der Magnetrollen fördert, bis beide Seiten gleichstraff sind. Wenn beide Seiten gleichstraff sind, ist das Material fertig ausgerichtet. Diese in Fig. 2a und 2b dargestellte ausgerichtete Stellung wird im Allgemeinen aber nicht durch einmaliges Betätigen der Magnetrollen erreicht, sondern durch einen mehrstufigen Prozess, bei dem die Magnetrollen nach einem Anfahren und Straffen des Bandes (dies wird selbstverständlich nicht weiter von der feststehenden Vorratsrolle 1 abgezogen, sondern rutscht mit der seitlichen Verschiebung auch in Förderrichtung auf den Magnetrollen 11 und 12 durch , das heißt, in Längsrichtung oberhalb der Magnetrolle 12 verschiebt sich die Bandkante nur, um den Unterschied zwischen dem durchhängenden Band 5 in Fig. 1a und dem gestrafften Band in Fig. 2a) umgesteuert werden, sodass das Band wieder in die Position nach Fig. 1a zurückläuft. Anschließend wird erneut angefahren und das Band wiederum gestrafft, da gerade im Augenblick des Straffens, das heißt des unsymmetrischen Straffens der einen Seitenkante gegenüber der anderen Seitenkante, eine besonders hohe Kraftkomponente in Querrichtung und damit ein gutes seitliches Verschieben in die gewünschte ausgerichtete Mittelstellung nach Fig. 2b erzeugt wird. Als zweckmäßig hat es sich dabei erwiesen, die Ausrichtvorrichtung mit einem Schrittsteuerprogramm für sechs Ausrichtschritte zu versehen. Die Umlenkrollen 15, 16 erfüllen den Zweck, den minimalen Biegeradius beim Ausrichten zu begrenzen. Sie sind drehbar gelagert und können seitlich auf der Achse 17 leicht verschoben werden, sodass sie dem Ausrichten wenig Widerstand entgegenbringen. Nach jedem Ausrichtschritt bringen die seitlichen Federn 18, 19 die Umlenkrollen 15, 16 in die mittige Ausgangslage zurück.After an operator has finished the end section 2 of the steel cord 5 as in Fig. 1b offset and laterally shifted attached to the magnetic rollers 11 and 12, these are set in rotation and thereby tension the steel cord in the Position according to Figures 2a and 2b. It tightens when attached wrong Band end 2 one side earlier than the other. This creates a lateral force generated on the tape end 2, this in the direction of the central axis of the magnetic rollers promotes until both sides are equally punished. If both sides are equal, is the material fully aligned. This aligned shown in Fig. 2a and 2b In general, position is not achieved by pressing the magnetic rollers once achieved, but through a multi-stage process in which the magnetic rollers after starting and tightening the belt (this goes without saying no longer pulled off the fixed supply roll 1, but slips with it the lateral displacement in the conveying direction on the magnetic rollers 11 and 12 by, that is, in the longitudinal direction above the magnetic roller 12 shifts the band edge only to tell the difference between the sagging band 5 in Fig. 1a and the tightened band in Fig. 2a) are reversed, so that Tape returns to the position shown in Fig. 1a. Then again started and the belt tightened again, because at the moment of the Tightening, that is, the asymmetrical tightening opposite one side edge the other side edge, a particularly high force component in the transverse direction and thus a good lateral shift into the desired aligned Middle position according to Fig. 2b is generated. It has proven to be useful proved the alignment device with a step control program for six alignment steps to provide. The deflection rollers 15, 16 serve the purpose of minimal Limit the bending radius when aligning. They are pivoted and can be easily moved laterally on the axis 17 so that they are aligned show little resistance. Bring after each alignment step the lateral springs 18, 19 the guide rollers 15, 16 in the central starting position back.

Nach dem erfolgten Ausrichten gemäß Fig. 2b wird, wie in den Fig. 3a und 3b dargestellt ist, das Cordband durch Umsteuern der Antriebsvorrichtung für die Magnetrollen 11 und 12 zurückgefahren, bis die Bandkante 21 exakt mit der durch das Kreuz 22 angegebenen Ansprechposition des Sensors 23 zusammenfällt. Anschließend wird die Spleißleiste 14 betätigt und die beiden Cordbandenden 2 und 3 überlappend miteinander verspleißt. Wegen der exakten Ausrichtung dieser Cordbandenden 2 und 3 gegeneinander bedarf es anschließend nur des Herausschneidens der eigentlichen Spleißstelle. Weitere Abfallabschnitte durch Verziehen und Versetzen der Bänder 2 und 3 gegeneinander fallen nicht an. Zusätzlich zu den Sensoren 23 und 24 für die Bandkante 21 des Bandabschnitts 2 des neu abzuziehenden Cordbandes 5 sind noch Sensoren 25 zum Anhalten der Abzugsrollen 8, 9 in der entsprechenden gewünschten Endstellung der Bandkante 26 des Bandendes 3 der vorherigen Vorratsrolle vorgesehen.After the alignment according to FIG. 2b has taken place, as shown in FIGS. 3a and 3b is, the cord band by reversing the drive device for the magnetic rollers 11 and 12 retracted until the band edge 21 exactly with the through the Cross 22 specified response position of the sensor 23 coincides. Subsequently the splice bar 14 is actuated and the two cord ends 2 and 3 overlapping spliced together. Because of the exact alignment of this Cord ends 2 and 3 against each other then only need to be cut out the actual splice. Further waste sections by warping and offset of the bands 2 and 3 against each other do not occur. additionally to the sensors 23 and 24 for the band edge 21 of the band section 2 of the new Cord 5 to be removed are still sensors 25 for stopping the take-off rollers 8, 9 in the corresponding desired end position of the band edge 26 of the End 3 of the previous supply roll is provided.
