Description
Die Erfindung betrifft eine Vorrichtung zur Aufnahme und zum Abwickeln von Endlosmaterial beinhaltenden Spulen gemäß gattungsbildendem Teil des ersten Patentanspruchs.The The invention relates to a device for receiving and unwinding of endless material containing coils according to generic part of the first claim.

Ziel des Erfindungsgegenstandes ist es einerseits, eine Vorrichtung zur Aufnahme und zum Abwickeln von Endlosmaterial, insbesondere gezogenem Drahtmaterial, beinhaltenden Spulen bereit zu stellen, die einfach und kompakt aufgebaut ist und wobei ein im Wesentlichen verschleißfreier und wartungsfreier Betrieb der Vorrichtung unabhängig von der Art des Endlosmaterials gegeben ist.aim the subject of the invention it is on the one hand, a device for Picking up and unwinding of continuous material, especially drawn Wire material, containing coils to provide that easy and is constructed compact and wherein a substantially wear-free and maintenance-free operation of the device regardless of the type of continuous material given is.
Darüber hinaus soll ein Regelschema der Zugkraft bei der Verarbeitung von aufgewickeltem Endlosmaterial vorgeschlagen werden, das unabhängig von der Änderung des Wickelradius beim Abwickeln des Endlosmaterials eine im Wesentlichen gleichmäßige Zugspannung im Endlosmaterial gewährleistet.Furthermore is a control scheme of traction in the processing of wound endless material be proposed that independently from the change the winding radius when unwinding the continuous material a substantially uniform tensile stress guaranteed in endless material.
Dieses Ziel wird dadurch erreicht, dass die Bremsvorrichtung einen mindestens einen Magneten beinhaltenden Magnethalter aufweist, der Magnethalter beim Abwickeln des Endlosmaterials nach dem Prinzip einer Wirbelstrombremse mit der Scheibe in Wirkverbindung bringbar ist und dass die Scheibe sowie der Magnethalter integraler Bestandteil des Gehäuses sind.This Goal is achieved in that the braking device has an at least a magnetic holder containing magnet, the magnet holder when unwinding the endless material according to the principle of an eddy current brake can be brought into operative connection with the disc and that the disc and the magnetic holder are an integral part of the housing.
Vorteilhafte Weiterbildungen der erfindungsgemäßen Vorrichtung sind den zugehörigen gegenständlichen Unteransprüchen zu entnehmen.advantageous Further developments of the device according to the invention are the associated representational dependent claims refer to.
Der Erfindungsgegenstand kann im Wesentlichen bei allen bekannten Endlosprodukten eingesetzt werden, wobei er jedoch bevorzugt für gezogene Endlosprodukte, wie beispielsweise Drahtcords, eingesetzt wird. Drahtcord wird beispielsweise bei der Herstellung von Reifen zur Erzeugung der Karkassen eingesetzt, indem in einem Gatter mehrere Spulen aufnehmende Vorrichtungen eingesetzt werden und die Endlosprodukte in Richtung des Produktionsbereiches der Karkasse abgewickelt werden. Hierbei ist es zwingend notwendig, dass sich auch bei reduzierendem Wickeldurchmesser der Spulen und somit sich erhöhender Umfangsgeschwindigkeit stets die gleiche Zugspannung im Endlosmaterial gegeben ist. Dies wird durch den Erfindungsgegenstand gewährleistet.The subject invention can be used essentially in all known continuous products, but it is preferably used for drawn continuous products, such as wire cords. Wire cord is used for example in the production of tires for the production of carcasses by a plurality of bobbin-receiving devices are used in a gate and the endless products are developed in the direction of the production area of the carcass. It is imperative that even with a reduced winding diameter of the coils and thus increasing the peripheral speed is always given the same tension in the continuous material. This is ensured by the subject invention.
Die erfindungsgemäße Magnetbremse arbeitet nach dem Prinzip einer Wirbelstrombremse, deren Funktionsweise gewährleistet, dass ein berührungsloses Bremsmoment, das durch Induktion von elektrischen Strömen in einer Bremsscheibe entsteht, gebildet wird. Nach der Lenzschen Regel sind die entstehenden Ströme und die damit verbundenen Magnetfelder dem Magnetfeld des erregenden Dauermagneten entgegengerichtet und erzeugen auf diese Art die berührungslose Bremswirkung.The Magnetic brake according to the invention works on the principle of an eddy current brake, whose operation guaranteed that a non-contact Braking torque caused by induction of electric currents in one Brake disc is formed, is formed. According to the Lenz rule, the resulting currents and the associated magnetic fields the magnetic field of the exciting Permanent magnets counter-directed and generate in this way the non-contact Braking effect.
Beim Abwickeln von Endlosmaterial wird die Zugspannung im Endlosmaterial durch mehrere Einflussgrößen beeinflusst.At the Unwinding endless material becomes the tension in the endless material influenced by several factors.
Zunächst ergibt sich eine Änderung der Zugkraft über die Änderung des Wickelradius. Daneben gibt es Spannungsspitzen durch unebene Oberflächen des möglicherweise verdrillten Endlosmaterials. Zusätzlich ergibt sich auf der nicht spielfreien Spindelaufhängung und deren Drehbewegung eine etwa sinusförmige Schwingung im Endlosmaterial.At first results a change the tensile force over the change the winding radius. In addition, there are spikes through uneven surfaces that possibly twisted endless material. additionally results from the non-backlash spindle suspension and The rotational movement of an approximately sinusoidal vibration in the endless material.
Die erfindungsgemäße Vorrichtung wirkt nun wie folgt allen genannten Einflussgrößen entgegen und zwar ähnlich einem PID-Regler, wie er in der Regelungstechnik verwendet wird.The inventive device acts now as follows all the above influencing variables and similar to one PID controller, as used in control engineering.
Die Änderung des Wickelradius hat eine Zunahme der Abrollgeschwindigkeit des Endlosmaterials zur Folge, der die Magnetbremse entgegenwirkt, so dass das Bremssystem mit zunehmender Abrollgeschwindigkeit stärker bremst. Die Spannungsspitzen durch das abgewickelte Endlosmaterial kompensiert eine Feder (Torsionsfeder), die in die Lagerung des Schwenkarmes integriert ist. Die auftretenden Schwingungen werden durch mehr oder weniger starkes Eintauchen des Magnethalters in den Bereich der Aluminiumscheibe gesteuert und über den Schwenkarm ausgeglichen.The change the winding radius has an increase in the unwinding speed of the Endlosmaterials result, which counteracts the magnetic brake, so that the braking system brakes more with increasing unwinding speed. The voltage peaks compensated by the unwound endless material a spring (torsion spring), which is in the bearing of the swivel arm is integrated. The vibrations that occur are more or less immersion of the magnet holder in the area the aluminum disc controlled and balanced over the swivel arm.
Durch das Zusammenspiel der genannten Regelmechanismen wird sich, unabhängig vom Winkelradius, im Endlosmaterial eine konstante Zugkraft ergeben.By the interaction of the mentioned control mechanisms will be independent of the Angular radius, yield a constant tensile force in continuous material.
Die Gehäusekonstruktion kann prinzipiell jeder Anschlussform und Spulenform angepasst werden, so dass sie problemlos auch durch andersartige ausgebildete Vorrichtungen ausgetauscht werden kann.The housing construction can in principle be adapted to any connection shape and coil shape, so that they can easily by other trained devices can be exchanged.
Als Vorteile dauermagnetischer Bremsen sind vor allem der verschleißfreie, berührungslose, wartungsfreie und stromausfallsichere Betrieb sowie die nahezu unbegrenzte Lebensdauer der verwendeten magnetisierten Komponenten zu nennen.When Advantages of permanent magnetic brakes are above all the wear-free, non-contact, maintenance-free and power fail-safe operation, as well as the almost unlimited life to name the magnetized components used.
