Description

Die vorliegende Erfindung betrifft eine Anwickel- und Schneidvorrichtung zum Anwickeln eines Drahtes an einen Stift, insbesondere Anschlußstift für elektrische Spulen und zum Abtrennen des überstehenden Drahtrestes.The present invention relates to a winding and cutting device for winding a wire onto a pin, in particular a connecting pin for electrical coils and for severing the excess wire.

Bislang ist es üblich, von Hand und unter Zuhilfenahme einer Pinzette die Drähte an die Anschlußstifte, z.B. für elektrische Spulen und dergl. anzuwickeln und die überstehenden Drahtreste,mittels eines Seitenschneiders abzutrennen. Soweit Vorrichtungen im Einsatz sind, zeichnen sich diese durch ihre erhebliche Aufwendigkeit aus.So far, it has been common to use manual tweezers to connect the wires to the connection pins, e.g. for electrical coils and the like. To wind up and to remove the excess wire by means of a side cutter. As far as devices are in use, they are characterized by their considerable complexity.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art zu schaffen, mittels der in einfacher Weise das Anwickeln eines Drahtes an einen Stift und das Abtrennen des überstehenden Drahtrestes in einem einzigen Arbeitsgang erfolgen. Die Vorrichtung soll darüber hinaus noch bei Abständen der Anschlußstifte von weniger als 10 mm, wie dies z.B. bei Spulenkörpern der Fall sein kann, einsetzbar sein und sich zudem durch einen so geringen Raumbedarf auszeichnen, daß ggf. auch mehrere Vorrichtungen zusammengefaßt werden können.The present invention has for its object to provide a device of the type mentioned, by means of which the winding of a wire onto a pin and the removal of the excess wire residue are carried out in a single operation. The device should also be able to be used at distances of the connecting pins of less than 10 mm, as can be the case, for example, with coil formers are also characterized by such a small space requirement that, if necessary, several devices can be combined.

Zur Lösung dieser Aufgabe sieht die Erfindung eine stationäre Hülse vor, innerhalb der ein Dorn drehbar angeordnet ist, wobei der Dorn eine mindestens zu seiner einen Stirnseite hin offene zentrische Bohrung aufweist, in die der Stift beim Anwickeln eintaucht und die mindestens im Wickelbereich einen wenigstens dem Wickeldurchmesser entsprechenden Durchmesser hat und wobei die Hülse und der Dorn einen mindestens nach der einen Stirnseite hin offenen und vorzugsweise tangential zur Bohrung gerichteten Schrägschlitz aufweisen.To achieve this object, the invention provides a stationary sleeve within which a mandrel is rotatably arranged, the mandrel having a central bore open at least towards its one end face, into which the pin dips during winding and which has at least one in the winding area Has a corresponding diameter of the winding and the sleeve and the mandrel have an oblique slot that is open at least towards one end face and preferably directed tangentially to the bore.

Zweckmäßigerweise ist der Dorn mit einem Antrieb, z.B. Getriebe-Elektromotor gekoppelt, dessen Steuerung so gewählt ist, daß in der Start- bzw. Ausgangsstellung der Vorrichtung die Schrägschlitze der Hülse und des Dorns fluchten.' Die Vorrichtung, deren Antrieb mittels eines Fußschalters betätigbar sein kann, ist z.B. auf einer Werkbank befestigbar, derart, daß diese in Richtung zum Anschlußstift weist.The mandrel is expediently coupled to a drive, for example a geared electric motor, the control of which is selected such that the oblique slots of the sleeve and the mandrel are aligned in the starting or starting position of the device. ' The device, the drive of which can be actuated by means of a foot switch, can be attached, for example, to a workbench, in such a way that it points towards the connecting pin.

Die Erfindung wird nachstehend anhand eines Ausführungsbeispieles näher erläutert. Es zeigt:

  • Fig. 1 in teilweise gebrochener und strichlinierter Darstellung eine Seitenansicht der Anwickel- und Schneidvorrichtung nach der Erfindung,
  • Fig. 2 eine Draufsicht auf die Vorrichtung nach Fig. 1,
  • Fig. 3 bis 6 die Wirkungsweise der Vorrichtung anhand von verschiedenen Arbeitsstellungen.
Gemäß Fig. 1 weist die Anwickel- und Schneidvorrichtung eine stationäre Hülse 2 auf. Innerhalb dieser Hülse ist ein Dorn 1 drehbar gelagert. Der Dorn 1 besitzt eine zentrische' Bohrung 3, die, wie dies bei 4 angedeutet ist, am Dorn-Stirnende erweitert ist. Die Länge und die lichten Weiten der Bohrung und der Erweiterung 4 sind bestimmt durch die maximale Anschlußstiftlänge, den Durchmesser des Anschlußstiftes und den Durchmesser des Anschlußstiftes samt Draht, d.h. den sogenannten Wickeldurchmesser. Die Tiefe des erweiterten Teiles 4 der Bohrung 3 richtet sich nach der gewünschten Wickellänge.The invention is explained in more detail below using an exemplary embodiment. It shows:
  • 1 is a partially broken and dashed line illustration of a side view of the winding and cutting device according to the invention,
  • 2 is a plan view of the device of FIG. 1,
  • 3 to 6 the operation of the device based on different working positions.
1, the winding and cutting device has a stationary sleeve 2. A mandrel 1 is rotatably mounted within this sleeve. The mandrel 1 has a central 'bore 3 which, as indicated at 4, is widened at the end of the mandrel. The length and the clear width of the bore and the extension 4 are determined by the maximum pin length, the diameter of the pin and the diameter of the pin including the wire, ie the so-called winding diameter. The depth of the enlarged part 4 of the bore 3 depends on the desired winding length.

Der Dorn 1 und die Hülse 2 besitzen je einen nach ihrer einen Stirnseite hin offenen und zur Bohrung samt Ausnehmung 4 gerichteten Schrägschlirz 5 bzw. 6.The mandrel 1 and the sleeve 2 each have an oblique slit 5 or 6, which is open toward one end side and directed toward the bore including the recess 4.

Die Wirkungsweise dieser Vorrichtung ist wie folgt: Durch einen entsprechend gesteuerten Antrieb werden zunächst der Dorn 1 und die Hülse 2 in eine Stellung zueinander befördert, in der die beiden Schrägschlitze 5 und 6 fluchten. Anschließend wird gemäß Fig. 3 und 4 ein Draht 11 in die Schrägschlitze eingelegt und z.B. ein Spulenkörper 10 samt Anschlußstift 7 in Pfeilrichtung B befördert, derart, daß der Anschlußstift (siehe Fig. 4) in die Bohrung 3 eintaucht.The operation of this device is as follows: First, the mandrel 1 and the sleeve 2 are conveyed to one another by a correspondingly controlled drive in a position in which the two oblique slots 5 and 6 are aligned. 3 and 4, a wire 11 is then inserted into the oblique slots and e.g. a bobbin 10 together with the pin 7 is conveyed in the direction of arrow B such that the pin (see Fig. 4) dips into the bore 3.

Durch Betätigung z.B. eines Fußschalters wird über einen in der Zeichnung nicht dargestellten Antrieb, z.B. Getriebe-Elektromotor, der Dorn 1 in Pfeilrichtung A bewegt, wobei mit Beginn der Drehbewegung das überstehende Drahtende an der in Fig. 2 mit 8 bezeichneten Schnittkante abgeschert wird und die im Dorn verbleibende Drahtlänge sich beim Weiterdrehen des Dorns restlos um den Anschlußstift 7 wickelt. Die Länge "a" (siehe Fig. 1)By actuating e.g. of a foot switch is operated via a drive not shown in the drawing, e.g. Geared electric motor, the mandrel 1 moves in the direction of arrow A, with the beginning of the rotary movement the protruding wire end is sheared off at the cutting edge denoted by 8 in FIG. The length "a" (see Fig. 1)
