The aim of the invention is to reduce the amount of space and the technical effort required to feed the front end of a wire coil into a wire drawing installation. To achieve this, the arm of the device is formed from a base section and an end section, whereby the end of the base section can pivot around a first pivotal axis and is connected to the base of a rotationally mounted holder and the pivotal axis of the base section runs perpendicular to the axis of rotation of said holder. One end of the end section can pivot around a second pivotal axis and is connected to the other end of the base section. The first and second pivotal axes run parallel to each other. The free end of the end section of the arm supports a head unit that is rotationally mounted around two axes that are located in a normal position to each other. A hook-shaped gripping element and a clamping device which dresses the front end of the wire coil are arranged on said head unit. Control units for swinging or rotating the holder, arm sections and head unit are provided.

Beschreibungdescription
Die Erfindung betrifft eine Vorrichtung zur Zuführung des Anfangsendes eines Drahtcoils zu einer Ziehanlage, mit einer Basis, auf der ein Halter drehbar gelagert ist und einem mit dem Halter verbundenen Arm, der an seinem Ende ein Greifelement zum Erfassen des Anfangsendes des Drahtcoils aufweist.The invention relates to a device for feeding the start end of a wire coil to a drawing system, having a base on which a holder is rotatably mounted and an arm connected to the holder, which has a gripping element at its end for grasping the start end of the wire coil.
Eine nach DD 41 927 bekannte Vorrichtung dieser Art hat einen Halter, auf dem ein radial verfahrbarer Arm angeordnet ist, der über einen Hubzylinder in der Höhe variiert werden kann. Der Arm trägt an seinem freien Ende ein Greifelement. Zum Erfassen des Anfangsendes eines Coils wird das Greifelement durch Drehen und Heben bzw. Senken des Arms in die gewünschte Position gebracht. Anschließend wird durch Verschwenken des Arms das Anfangsende des Drahtes über Richtrollen einer Klemmzange, die das Material in Arbeitsrichtung vorführt, zugeführt. Danach folgt dann der eigentliche Drahtziehvorgang.A device of this type known according to DD 41 927 has a holder on which a radially movable arm is arranged, the height of which can be varied by means of a lifting cylinder. The arm carries a gripping element at its free end. To grasp the start end of a coil, the gripping element is brought into the desired position by rotating and lifting or lowering the arm. Then, by swiveling the arm, the start end of the wire is fed via straightening rollers to a pair of clamping tongs that shows the material in the working direction. Then the actual wire drawing process follows.
Eine derartige Vorrichtung erfordert einen erheblichen Raumbedarf, um die notwendigen Drehbewegungen zu ermöglichen. Darüber hinaus müssen die Greifelemente das Anfangsende des Drahtes klemmen, und es müssen zusätzlich Einrichtungen zum Richten des Drahtes in der Anlage vorgesehen sein.Such a device requires a considerable amount of space to enable the necessary rotary movements. In addition, the gripping elements must clamp the start end of the wire and additional devices for straightening the wire must be provided in the system.
Die Aufgabe der vorliegenden Erfindung besteht nun darin, eine Vorrichtung der eingangs erwähnten Art zu schaffen, die demgegenüber sowohl den Raumbedarf als auch den apparativen Aufwand erheblich reduziert. Zur Lösung dieser Aufgabe ist erfindungsgemäß bei einer Vorrichtung der eingangs erwähnten Art vorgesehen, daß der Arm aus einem Basisabschnitt und einem Endabschnitt gebildet ist, daß der Basisabschnitt mit seinem einen Ende um eine erste Schwenkachse schwenkbar mit dem auf der Basis drehbar gelagerten Halter verbunden ist, wobei die Schwenkachse des Basisabschnitts quer zur Drehachse des Halters verläuft, daß ein Ende des Endabschnitts um eine zweite Schwenkachse mit dem anderen Ende desThe object of the present invention is now to provide a device of the type mentioned at the outset which, on the other hand, considerably reduces both the space requirement and the outlay on equipment. To achieve this object, it is provided according to the invention in a device of the type mentioned at the outset that the arm is formed from a base section and an end section, that the base section is connected at one end to the holder rotatably mounted on the base so that it can pivot about a first pivot axis, wherein the pivot axis of the base portion is transverse to the axis of rotation of the holder that one end of the end portion about a second pivot axis with the other end of the
Basisabschnitts schwenkbar verbunden ist, daß die erste und die zweite Schwenkachse und parallel zueinander verlaufen, daß der Endabschnitt des Arms an seinem freien Ende eine um zwei normal zueinander verlau- fende Achsen und drehbar gelagerte Kopfeinheit trägt, an der ein hakenförmiges Greifelement und eine das Anfangsende des Drahtcoils richtende Klemmvorrichtung angeordnet sind, und daß Steuereinheiten zum Verschwenken oder Drehen des Halters, der Armabschnitte und der Kopfeinheit vorgesehen sind.Base section is pivotally connected, that the first and the second pivot axis and parallel to each other, that the end portion of the arm carries at its free end a head unit about two normal axes and rotatably mounted, on which a hook-shaped gripping element and one the beginning end of the wire coil directing clamping device are arranged, and that control units are provided for pivoting or rotating the holder, the arm sections and the head unit.
Durch die erfindungsgemäße Aufteilung des Arms in zwei Abschnitte ist der erforderliche Raumbedarf sowohl in der Arbeitsstellung wie auch in der Bereit-Stellung erheblich reduziert. Zudem erfüllt hier die Klemmvorrichtung gleichzeitig eine Richtfunktion. Dies hat zur Folge, daß gegenüber dem Stand der Technik eine Klemmvorrichtung entfallen kann, die lediglich dazu dient, das Anfangsende des Drahtes einer Richteinheit zuzuführen. Die Vorrichtung eignet sich dabei insbesondere für Drahtdurchmesser von 10 mm und darüber.By dividing the arm into two sections according to the invention, the required space is considerably reduced both in the working position and in the ready position. In addition, the clamping device also fulfills a directional function here. The consequence of this is that, compared to the prior art, there is no need for a clamping device which merely serves to feed the start end of the wire to a straightening unit. The device is particularly suitable for wire diameters of 10 mm and above.
Das Anfangsende des Drahtes wird mittels der Vorrichtung in eine Ziehmaschine eingestoßen, kann aber auch einer dieser Maschine vorgeschalteten Anspitzeinheit zugeführt werden.The start end of the wire is pushed into a drawing machine by means of the device, but can also be fed to a sharpening unit upstream of this machine.
Erfindungsgemäß ist ferner vorgesehen, daß das Greifelement an der Kopfeinheit gesteuert schwenkbar gelagert ist. Auf diese Weise kann das Erfassen und Einführen des Drahtelements in die Klemmvorrichtung gefördert werden.According to the invention it is further provided that the gripping element is pivotally supported on the head unit in a controlled manner. In this way, the detection and insertion of the wire element into the clamping device can be promoted.
Erfindungsgemäß ist ferner vorgesehen, daß die Steuereinheiten Hydraulik- oder Pneumatikeinheiten sind. Erfindungsgemäß ist ferner vorgesehen, daß die Klemmvorrichtung aus zwei Reihen von Druckrollen gebildet ist, die den Draht zwischen sich führen und vorrichten.According to the invention it is further provided that the control units are hydraulic or pneumatic units. According to the invention it is further provided that the clamping device is formed from two rows of pressure rollers which guide and align the wire between them.
Erfindungsgemäß ist ferner vorgesehen, daß die Reihen der Druckrollen relativ zueinander einstellbar gelagert sind.According to the invention it is further provided that the rows of the pressure rollers are mounted adjustable relative to each other.
Erfindungsgemäß ist ferner vorgesehen, daß einzelne Druckrollen einer Reihe relativ zu Druckrollen der anderen Reihe einstellbar gelagert sind.According to the invention it is further provided that individual pressure rollers of one row are mounted so as to be adjustable relative to pressure rollers of the other row.
Erfindungsgemäß ist ferner vorgesehen, daß zumindest zwei einander gegenüberliegend angeordnete Druckrollen mit einem Drehantrieb verbunden sind.According to the invention it is further provided that at least two pressure rollers arranged opposite one another are connected to a rotary drive.
Schließlich ist erfindungsgemäß vorgesehen, daß der Drehantrieb in seiner Drehrichtung umsteuerbar ist. Dadurch wird es möglich, mit nur einer erfindungsgemäßen Vorrichtung zwei Linien von Drahtziehmaschinen zu bedienen, wobei die Vorrichtung dann mit zwei Coils zusammenarbeitet, die jeweils auf einem Haspel sitzen. Zweckmäßigerweise steht die Vorrichtung dabei zwischen den beiden Linien.Finally, the invention provides that the rotary drive can be reversed in its direction of rotation. This makes it possible to operate two lines of wire drawing machines with only one device according to the invention, the device then working together with two coils, each sitting on a reel. The device expediently stands between the two lines.

Der Kolben 4 der Kolben- Zylinder-Einheit 3 ist an einen Ansatz 5 des Halters 2 angelenkt, so daß eine Bewegung des Kolbens 4 zu einer Drehung des Halters 2 bezüglich der Basis 1 führt. Mit dem Halter 2 ist ein Basisabschnitt 6 eines Arms um eine Achse 7 schwenkbar verbunden. Eine Kolben- Zylinder-Einheit 8 ist einerseits an dem Halter 2 und andererseits an dem Basisabschnitt 6 angelenkt.3 shows a plan view of the device according to FIGS. 1 and 2. The device has a base 1 on which a holder 2 is rotatably mounted. A piston-cylinder unit 3 is pivotally mounted on the base 1. The piston 4 of the piston-cylinder unit 3 is articulated to a shoulder 5 of the holder 2, so that a movement of the piston 4 leads to a rotation of the holder 2 with respect to the base 1. A base portion 6 of an arm is pivotally connected to the holder 2 about an axis 7. A piston-cylinder unit 8 is articulated on the one hand on the holder 2 and on the other hand on the base section 6.
Der Basisabschnitt 6 ist im wesentlichen L-förmig ausgebildet.The base section 6 is essentially L-shaped.
An das Ende des Basisabschnitts 6 ist über eine Achse 9 ein im wesentlichen geradlinig verlaufender Endabschnitt 10 angeschlossen. Eine Kolben-Zylinder-Einheit 11 ist einerseits an dem Basisabschnitt 6 und andererseits an dem Ende 12 des Endabschnitts 10 des Arms schwenkbar angelenkt.A substantially rectilinear end section 10 is connected to the end of the base section 6 via an axis 9. A piston-cylinder unit 11 is pivotally articulated on the one hand on the base section 6 and on the other hand on the end 12 of the end section 10 of the arm.
Der Endabschnitt 10 trägt eine Kopfeinheit 13, die sowohl um die Achse 14 sowie um die Achse 15 drehbar ist. Diese beiden Achsen verlaufen normal zueinander.The end section 10 carries a head unit 13, which is rotatable both about the axis 14 and about the axis 15. These two axes are normal to each other.
Eine Kolben-Zylinder-Einheit 16 dient zum Drehen der Kopfeinheit 13 um die Achse 14. Die Kolben-Zylinder-Einheit 16 stützt sich mit dem einen Ende an dem Endabschnitt 10 und an ihrem anderen Ende an einem Hebel 17 ab.A piston-cylinder unit 16 serves to rotate the head unit 13 about the axis 14. The piston-cylinder unit 16 is supported at one end on the end section 10 and at its other end on a lever 17.
Die Kopfeinheit 13 trägt ein hakenförmiges Greifelement 18, das mittels einer Kolben- Zylinder-Einheit 19 in seiner Neigung zu der Kopfeinheit 13 einstellbar ist.The head unit 13 carries a hook-shaped gripping element 18, which can be adjusted in its inclination to the head unit 13 by means of a piston-cylinder unit 19.
Weiter ist die Kopfeinheit 13 mit einem Klemmelement in Form von Druckrollen 20 versehen, die in zwei einander gegenüberliegenden Reihen angeordnet sind und zwischen sich ein von dem Greifelement zugeführtes Drahtende aufnehmen und weiterführen. Zumindest zwei einander gegenüberliegende Druckrollen 20 sind mit einem Drehantrieb gekoppelt. Die Druckrollen 20 sind so positioniert und einstellbar, daß sie den zwischen ihnen geführten Draht richten. Der Drehantrieb ist zweckmäßigerweise in seiner Drehrichtung reversierbar.Furthermore, the head unit 13 is provided with a clamping element in the form of pressure rollers 20, which are arranged in two mutually opposite rows and between them receive and continue a wire end fed by the gripping element. At least two opposing pressure rollers 20 are coupled to a rotary drive. The pressure rollers 20 are positioned and adjustable to direct the wire passed between them. The rotary drive is expediently reversible in its direction of rotation.
Wenn nun das Anfangsende eines Coils einer Drahtziehmaschine zugeführt werden soll, so wird der aus dem Basisabschnitt 6 und dem Endabschnitt 10 gebildete Arm durch Betätigung der Kolbenzylindereinheiten 8 und 11 so ausgefahren, daß das hakenförmige Greifelement 18 durch entsprechende Drehungen der Kopfeinheit 13 das Anfangsende eines auf einer Haspel 21 sitzenden Drahtcoils 22 erfaßt. Das Greifelement 18 wird dann so verlagert, daß das Anfangsende des Drahtes zwischen die beiden Reihen der Druckrollen 20 eingeführt und durch diese gerichtet und weitergeleitet wird. Danach dann folgt eine Drehung des Halters 2 in die in Figur 3 strichpunktierte Position. Die Kopfeinheit 13 wird dabei so positioniert, daß das in ihr gehaltene, gerichtete Drahtende in den Einlauf einer Drahtziehmaschine eingestoßen oder einer Anspitzeinheit der Drahtziehanlage übergeben wird. Die Vorrichtung wird anschließend in die in Figur 1 dargestellte Position zurückgeführt. Die Vorrichtung kann ausgehend von auf separaten Haspeln sitzenden Coils zwei Linien von Ziehmaschinen bedienen. If the start end of a coil is to be fed to a wire drawing machine, the arm formed from the base section 6 and the end section 10 is extended by actuating the piston-cylinder units 8 and 11 such that the hook-shaped gripping element 18 opens the start end of one by corresponding rotations of the head unit 13 a reel 21 seated wire coils 22 detected.
