Description

Die Erfindung betrifft eine Vorrichtung zum Bewickeln eines Spulenkörpers mit Hilfe eines Drahtführungsröhrchens, das zum Anwickeln von Drahtenden an Anschlußstifte des Spulenkörpers Verfahrbewegungen um die Anschlußstifte ausführt, und zum Abtrennen der von den Anschlußstiften überstehenden Drahtstücke mit Hilfe einer Trenneinrichtung.The invention relates to a device for winding a coil body with the aid of a wire guide tube, which carries out traversing movements around the connection pins for winding wire ends onto connection pins of the coil body, and for severing the wire pieces projecting from the connection pins with the aid of a separating device.

Bei einer derartigen, aus der DE-AS 26 32 671 bekannten Vorrichtung ist eins von mehreren Drahtführungsröhrchen an einem in drei Freiheitsgraden gegenüber einem Spulenkörper auf einer Wickelspindel verfahrbaren Führungskörper gehalten. Zum Bewickeln des Spulenkörpers führt das Drahtführungsröhrchen den aufzuwickelnden Draht von einer zuvor bereits fertiggewickelten Spule an einen ersten Anschlußstift des nunmehr zu bewickeinden Spulenkörpers und wickelt den Draht dort an; nachfolgend wird der Drahtabschnitt zwischen dem ersten Anschlußstift und der bereits gewickelten Spule mit Hilfe einer Trenneinrichtung abgetrennt. Daraufhin wird mit Hilfe des Drahtführungsröhrchens zuerst der Spulenkörper bewickelt und danach der Draht an einem zweiten Anschlußstift des Spulenkörpers angewickeltIn such a device, known from DE-AS 26 32 671, one of several wire guide tubes is held on a guide body which can be moved in three degrees of freedom with respect to a coil former on a winding spindle. To wind the bobbin, the wire guide tube leads the wire to be wound up from a previously finished bobbin to a first terminal pin of the bobbin to be wound and winds the wire there; subsequently the wire section between the first connection pin and the already wound coil is cut off with the aid of a separating device. Then, with the help of the wire guide tube, the bobbin is first wound and then the wire is wound on a second connecting pin of the bobbin

Bei einer weiteren, aus der US-PS 3 306 554 bekannten Vorrichtung wird ein mit Hilfe eines Drahtführungsröhrchens auf einen Spulenkörper aufzubringender Draht zunächst an Hiffsstiften angewickelt, die an einer den zu bewickelnden Spulenkörper aufnehmenden Wickelspindel angeordnet sind; ein Anwickeln des Drahtes an Anschlußstifte des Spulenkörpers ist nicht vorgesehen. Die Abtrennung der von den Hilfsstiften überstehenden Drahtstücke erfolgt durch eine vom Drahtführungsröhrchen getrennt angeordnete Trenneinrichtung, die aus zwei konzentrisch und formschtÜssig angeordneten Hülsen mit je einem Längsschlitz besteht Dabei werden die Drahtstücke des in den Längsschlitzen eingebrachten Drahtes durch eine Drehbewegung der einen Hülse relativ zu der anderen Hülse abgetrenntIn a further device known from US Pat. No. 3,306,554, a wire which is to be applied to a bobbin with the aid of a wire guide tube is first wound on hipping pins which are arranged on a winding spindle which receives the bobbin to be wound; a winding of the wire on connection pins of the coil former is not provided. The wire pieces protruding from the auxiliary pins are separated by a separating device, which is separated from the wire guide tube and consists of two concentrically and positively arranged sleeves, each with a longitudinal slot.The wire pieces of the wire inserted in the longitudinal slots are rotated relative to the other by one sleeve Separated sleeve

Weiterhin ist aus der DE-OS 24 43 313 eine Einrichtung bekannt, die aus einer langgestreckten Düse, einem Fanghaken und einer Schneidehülse besteht Nach beendetem Wickeln einer Spule mittels eines Drahtführungsröhrchens wird diese Einrichtung an den von dem Drahtführungsröhrchen an einer Klemmstelle festgelegten Draht herangeführt der Draht ergriffen und mittels der die Düse konzentrisch umgebenden Schneidehülse abgeschnitten; anschließend wird der Draht von der Düse um einen Anschlußstift der Spule gewickelt und das Drahtende an den Anschlußstift angedrückt Das Bewickeln der Spule und das Anwickeln des Drahtes an Anschlußstifte erfolgt also mit Hilfe unterschiedlicher Werkzeuge.Furthermore, from DE-OS 24 43 313 a device is known which consists of an elongated nozzle, a catch hook and a cutting sleeve. After winding a coil by means of a wire guide tube, this device is brought up to the wire defined by the wire guide tube at a clamping point of the wire seized and cut off by means of the cutting sleeve concentrically surrounding the nozzle; then the wire is wound from the nozzle around a connecting pin of the coil and the end of the wire is pressed onto the connecting pin. The winding of the coil and the winding of the wire on connecting pins are thus carried out with the aid of different tools.

Durch die DE-OS 25 58 057 ist bei einer Vorrichtung zum Bewickeln eines Spulenkörpers eine Hülse bekannt, die über einen bereits bewickelten Anschlußstift gestülpt wird. Die Hülse drückt die Drahtwindungen zusammen, und eine an der Hülse ausgebildete Schneide trennt das überstehende Ende ab.From DE-OS 25 58 057 a sleeve is known in a device for winding a bobbin, which is put over an already wound terminal pin. The sleeve compresses the turns of the wire and a cutting edge formed on the sleeve cuts off the protruding end.

Die DE-AS 27 10 551 zeigt demgegenüber eine Anwickelhülse, die zwar gleichfalls über einen Anschlußstift gestülpt wird, aber mit Hilfe eines einen integralen Bestandteil der Anwickelhülse bildenden Greifhakens den von einer Klemme gehaltenen Draht erfaßt und durch Drehbewegung um den Anschlußstift wickelt Ein Abtrennen des Drahtes wird von dieser AnwickelhÜlse nicht vorgenommen, sondern es wird der gesamte zwtschen dem Anschuβstift und der Klemme aufgespannte Drahtabschnitt um den Anschlußstift gewickeltDE-AS 27 10 551, on the other hand, shows a winding sleeve which is also slipped over a connecting pin, but with the aid of a gripping hook forming an integral part of the winding sleeve, grips the wire held by a clamp and winds it around the connecting pin by rotating movement is not carried out by this winding sleeve, but the entire wire section stretched between the connecting pin and the terminal is wound around the connecting pin

Der Erfindung liegt die Aufgabe zugrunde, das Wickeln der Spule und das Anwickeln des Drahtes an die Anschlußstifte im Zusammenhang mit dem Abschneiden des Drahtes apparativ zu vereinfachen und den für diese Vorgänge insgesamt benötigten Zeitbedarf zu verringern.The invention has for its object to simplify the winding of the coil and the winding of the wire to the pins in connection with the cutting of the wire in terms of apparatus and to reduce the total time required for these processes.

Die erfindungsgemäße Lösung der Aufgabe besteht darin, daß bei der Vorrichtung der eingangs angegebenen Art die Trenneinrichtung eine Hülse mit einer Schneide aufweist, daß die Hülse konzentrisch zum Drahtführungsröhrchen an diesem beweglich angeordnet ist und daß das Drahtführungsröhrchen eine Schneideauflage zur Abstützung eines außerhalb des Drahtführungsröhrchens gegen dessen Längsachse geneigt geführten Drahtes aufweist.The solution of the task according to the invention is that in the device of the type mentioned, the separating device has a sleeve with a cutting edge, that the sleeve is concentrically arranged on the wire guide tube and that the wire guide tube has a cutting support for supporting an outside of the wire guide tube against it Has longitudinally inclined wire.

Die Vorrichtung gemäß der Erfindung hat den Vorteil, daß nur ein einziges Werkzeug für alle Wickelvorgänge einer Spule benötigt wird. Bei den bekannten Vorrichtungen notwendige Verfahrbewegungen in der Phase des Werkzeugwechsels sind damit vermieden. Darüberhinaus kann die erfindungsgemäße Vorrichtung sowohl bei Spulenkörpern mit radialen, als auch bei solchen mit axialen Anschlußstiften verwendet werden.The device according to the invention has the advantage that only a single tool is required for all winding processes of a coil. In the known devices necessary movements in the phase of the tool change are avoided. In addition, the device according to the invention can be used both in the case of bobbins with radial as well as those with axial connecting pins.

Falls die Hülse außerhalb des Drahtführungsröhrchens angeardnet ist und die Schneideauflage an der Außenseite des Mantels des Drahtführungsröhrchens ausgebildet ist, wird das Drahtende so knapp am Anschlußstift abgeschnitten, daß es nicht absteht und das Andrucken entfällt.If the sleeve is attached outside of the wire guide tube and the cutting support is formed on the outside of the jacket of the wire guide tube, the wire end is cut so close to the connecting pin that it does not stick out and there is no need to apply pressure.

Das Straffhalten des Drahtes während des Schneidevorganges wird erleichtert, wenn sich die Schneidteauflage zwischen der Auslauföffnung des Drahtführungsröhrchens und der Schneide der Hülse befindet, wobei der der Aus-Isuföffnung zugewandte Teil der Hülse als Schneide ausgebildet ist Der Hub der Hülse wird dadurch möglichst kurz gehalten, daß sich die Schneideauflage und die Schneide im Bereich der Auslauföffnung befinden.The tensioning of the wire during the cutting process is facilitated if the cutting support is located between the outlet opening of the wire guide tube and the cutting edge of the sleeve, the part of the sleeve facing the outflow opening being designed as a cutting edge. The stroke of the sleeve is thereby kept as short as possible, that the cutting support and the cutting edge are in the area of the outlet opening.

Zur Erzielung eines sauberen und sicheren Schnittes ist es vorteilhaft, die Schneide der Hülse formschlüssig zum Drahtführungsröhrchen auszubilden. Um der Verletzung des an die Anschlußstifte angewickelten und des aus dem Drahtführungsröhrchen herausragenden Drahtes während des Schneidevorgangs vorzubeugen, sollte die Schneide zungenförmig über das Ende der Hülse hinausragend ausgebildet sein.In order to achieve a clean and safe cut, it is advantageous to form the cutting edge of the sleeve in a form-fitting manner with the wire guide tube. In order to prevent injury to the wire wound on the connecting pins and the wire protruding from the wire guide tube during the cutting process, the cutting edge should be designed in the manner of a tongue and protrude beyond the end of the sleeve.

Der zu durchtrennende Draht wird mit Hilfe einer einfachen Maßnahme zuverlässig geführt, wenn das Drahtführungsröhrchen eine gegen seine Längsachse geneigt verlaufende, nut- oder kerbenartige Ausnehmung aufweist deren der Auslauföffnung nächstliegende Wand als Schneideauflage ausgebildet ist Ist die Ausnehmung darüber hinaus so tief ausgebildet, daß sie zumindest annähernd bis zur Mitte des Drahtführungsröhrchens reicht, so kommt dies wiederum einem sauberen Schnitt zugute. Dem Verklemmen des Drahtes im Mantel des Drahtführungsröhrchens wird vorgebeugt, wenn in der Ausnehmung Anschläge für den abzutrennenden Draht ausgebildet sind, die aus senkrecht auf der Schneideauflage stehenden Mantelabschnitten des Drahtführungsröhrchens bestehen. Die Funktion der Ausnehmung kann aber auch durch einen Vorsprung realisiert sein, der als Schneideauflage an das Drahtführungsröhrchen angeformt ist Die Schneideufiage bzw. scharfe Begrenzungskanten derselben können unter Umständen auch dazu ausgenutzt werden, einen zwischen einer Umlenkstelle und dem Drahtfühnungsröhrchen aufgespannten Grahtabschnitt zu reißen. Dies erfolgt durch entsprechende gegen den Drahtabschnitt gerichtete Verfahrbewegungen des Drahtführungsröhrchens; die Schneidhülse führt keine Relativbewegung zum Drahtführungsröhrchen aus. Ein Reißen von Drähten wird zuweilen, insbesondere bei sehr dünnen Drähten, gegenüber dem Schneiden derselben bevorzugtThe wire to be cut is reliably guided with the aid of a simple measure if the wire guide tube has a groove-like or notch-like recess which is inclined with respect to its longitudinal axis and the wall of which is closest to the outlet opening is designed as a cutting support extends almost to the middle of the wire guide tube, so this again benefits from a clean cut. The jamming of the wire in the jacket of the wire guide tube is prevented if stops for the wire to be separated are formed in the recess, which stops consist of jacket sections of the wire guide tube standing vertically on the cutting support. The function of the recess can, however, also be realized by a projection which is formed on the wire guide tube as a cutting support. The cutting attachment or sharp boundary edges thereof can also be used under certain circumstances to tear a portion of the grain stretched between a deflection point and the wire guide tube. This is done by corresponding movement of the wire against the wire section Wire guide tube; the cutting sleeve does not move relative to the wire guide tube. Tearing of wires is sometimes preferred over cutting them, especially with very thin wires

Zur Erläuterung der Erfindung anhand eines Ausführungsbeispieles wird nachfolgend auf drei Figuren Bezug genommen. Es zeigen:

  • Figur 1 ein Drahtführungsröhrchen in zwei Positionen, die während des Bewickelns eines Spulenkörpers eingenommen werden,
  • Figur 2 einen Längsschnitt durch das Drahtführungsröhrchen mit Hülse und
  • Figur 3 einen Querschnitt durch das Drahtführungsröhrchen während des Schneidevorganges.
To explain the invention using an exemplary embodiment, reference is made below to three figures. Show it:
  • FIG. 1 shows a wire guide tube in two positions, which are taken up during the winding of a coil former,
  • Figure 2 shows a longitudinal section through the wire guide tube with sleeve and
  • Figure 3 shows a cross section through the wire guide tube during the cutting process.

Die in Figur 1 ausschnitthaft dargestellte Wickelstation ist mit einem Drahtführungsröhrchen 1 ausgestattet Es weist eine konzentrische Hülse 2 mit Schneide 3 auf. Ein nicht dargestelltes, dreiachsiges Verlege- und Anwickelsyetem eorgt für die Positionierung des Drahtführungsröhrchens 1 und der es umschließenden Hülse 2. Um mit dem Wickelvorgang beginnen zu können, wird ein Draht 4 zunächst von einer Klemmvorrichtung 5 aufgenommen. Ober einen Umlenkstift 6 wird der Draht 4 mittels des Drahtführungsröhrchen 1 zu einem Anschlußstift 7a eines Sputenkörpers 8 geleitet und um den Anschlußstift 7a gewickelt Dann wird das Drahtführungsröhrchen 1 aus der Position I, in der der zwischen dem AnschluBstift 7a und dem Umlenkstift 6 gespannte Draht 4 in der Ausnehmung 9 zu liegen kommt, möglichst nahe an den Anachlußstift 7a herangeführt. Das vom Anschlußstift 7a abstehende Drahtende beträgt dann maximal 1 mm, wodurch der Lötzinnverbrauch beim späteren Verlöten bzw. die Güte der Lötung günstig beeinflußt werden. Anschließend wird die Hülse 2 mit der Schneide 3 hinunterbewegt und der Draht 4 abgetrennt. Die Schneide 3 ist zungenförmig an die Hülse 2 angeformt und umfaßt nur einen Teil des Umfanges des Drahtführungsröhrchens 1, damit während des Abtrennvorganges nicht auch noch der aus einer Auslauföffnung 10 des Drahtführungsröhrchens 1 herausragende Draht 4 beschädigt oder gar abgeschnitten wird. Zu diesem Zweck ist auch der Hub der Hülse 2 entsprechend begrenzt.The winding station shown in detail in FIG. 1 is equipped with a wire guide tube 1. It has a concentric sleeve 2 with a cutting edge 3. A triaxial laying and winding system (not shown) takes care of the positioning of the wire guide tube 1 and the sleeve 2 surrounding it. Via a deflection pin 6, the wire 4 is guided by means of the wire guide tube 1 to a connection pin 7a of a sput body 8 and wound around the connection pin 7a. Then the wire guide tube 1 is moved out of position I, in which the wire 4 stretched between the connection pin 7a and the deflection pin 6 comes to rest in the recess 9, brought as close as possible to the connecting pin 7a. The wire end protruding from the connecting pin 7a is then at most 1 mm, as a result of which the consumption of solder during later soldering or the quality of the soldering is influenced in a favorable manner. Then the sleeve 2 is moved down with the cutting edge 3 and the wire 4 is cut off. The cutting edge 3 is formed in a tongue-like manner on the sleeve 2 and comprises only part of the circumference of the wire guide tube 1, so that the wire 4 projecting from an outlet opening 10 of the wire guide tube 1 is not damaged or even cut off during the separation process. For this purpose, the stroke of the sleeve 2 is also limited accordingly.

Anschließend wird das Drahtführungsröhrchen 1 zum Spulenkörper 8 verfahren. Seine Bewickelung erfolgt auf herkömmliche Art und Weise. Dann wird der Draht 4 mittels des Drahtführungsröhrchens 1 um den zweiten Anschlußstift 7b gewickelt Nach dem Umfahren eines Hilfsstiftes 11 erreicht das Drahtführungsröhrchen 1 die Position II. Das Drahtführungsröhrchen 1 mit der Hülse 2 ist in dieser Lage strichpunktiert dargestellt Der vom zweiten Anschlußstift 7b wegführende Draht 4 wird auf gleiche Weise wie beim ersten Anschlußstift 7a abgetrennt Damit ist ein Wickelvorgang beendet und der nächste beginnt mit dem Verfahren des Drahtführungsröhrchens 1 zur Klemmvorrichtung 5 und dem Festlegen des Drahtes 4.The wire guide tube 1 is then moved to the coil former 8. It is wound in a conventional manner. Then the wire 4 is wound around the second connection pin 7b by means of the wire guide tube 1. After bypassing an auxiliary pin 11, the wire guide tube 1 reaches the position II. The wire guide tube 1 with the sleeve 2 is shown in this position by dash-dotted lines. The wire 4 leading away from the second connection pin 7b is separated in the same way as for the first connecting pin 7a. This ends one winding process and the next begins with the movement of the wire guide tube 1 to the clamping device 5 and the fixing of the wire 4th

Anhand der Figuren 2 und 3 werden die für den Schneidevorgang wichtigen Teile des Drahtführungsröhrchens 1 und der Hülse 2 erläutert. Nahe der Auslauföffnung 10 befindet sich die Ausnehmung 9. In dieser kommt der abzutrennende Draht 4 nach geeigneten Verfahrbewegungen des Drahtführungsröhrchens 1 zu liegen. Eine Schneideauflage 12 und eine Anschtagftäche 13 sorgen für eine definierte Lage des Drahtes 4. Zu seiner besseren Fixierung sollte er leicht gespannt sein. Die Bewegung der Hülse 2 in Richtung auf die Auslauföffnung 10 bewirkt das Durchtrennen des Drahtes 4 durch die Schneide 3, die einstückig an der Hülse 2 angeformt istThe parts of the wire guide tube 1 and the sleeve 2 which are important for the cutting process are explained with reference to FIGS. 2 and 3. The recess 9 is located near the outlet opening 10. The wire 4 to be separated comes to lie in this after suitable movement movements of the wire guide tube 1. A cutting support 12 and a contact surface 13 ensure a defined position of the wire 4. To fix it better, it should be slightly tensioned. The movement of the sleeve 2 in the direction of the outlet opening 10 causes the wire 4 to be cut through by the cutting edge 3, which is integrally formed on the sleeve 2

Die Erfindung umfaßt noch weitere funktionsgleiche Variationen der Ausgestaftung des Drahtführungsröhrchens und der Hülse mit Schneide. So wäre es ohne weiteres möglich, die Hülse mit Schneide innerhalb des Drahtführungsröhrchens unterzubringen, ohne den Ablauf des Drahttrennvorganges zu verändern. Eine entsprechende Anordnung von Schneideauflage und Schneide ermöglicht es auch, bei über das Drahtführungsröhrchen hinaus verlängerter Hülse das Durchtrennen des Drahtes bei entgegengesetzter Bewegungsrichtung der Hülse durchzuführen. Beispielsweise könnte dann die Ausnehmung im Drahtführungsröhrchen entfallen, die Auslauföffnung als Schneideauflage dienen und eine Ausnehmung mit Schneide wäre im über das Drahtführungsröhrchen hinausragenden Teil der Hülse vorzusehen. Dabei ist natürlich zu beachten, daß der Drahtauslauf dann nicht mehr über das Drahtführungsröhrchen erfolgt, sondern um den darüber hinausragenden Teil der Hülse verlängert wird und sich während des Trennvorganges durch die Bewegung der Hüise verkürzt, wes unter Umständen die Spannung des verlegten Drahtes lockertThe invention also includes other functionally identical variations in the configuration of the wire guide tube and the sleeve with cutting edge. So it would be easily possible to accommodate the sleeve with cutting edge within the wire guide tube without changing the course of the wire cutting process. A corresponding arrangement of cutting support and cutting edge also makes it possible to cut the wire with the sleeve extended beyond the wire guide tube with the sleeve moving in the opposite direction. For example, the recess in the wire guide tube could then be omitted, the outlet opening could serve as a cutting support, and a recess with a cutting edge would have to be provided in the part of the sleeve protruding beyond the wire guide tube. Of course, it should be noted that the wire run-out no longer takes place via the wire guide tube, but is extended by the protruding part of the sleeve and is shortened by the movement of the sleeve during the cutting process, which may loosen the tension of the laid wire
