Description

♦ 5

The invention relates to a device on a coil winding machine for winding layers a coil on a bobbin with an end flange, the two parallel to the end flange plane Has coil wire connection pins, the device being rotatable and eccentric A wire guide arranged on the axis of rotation for winding the coil wire ends onto the connecting pins fowie has a winding spindle and a winding mandrel receiving the bobbin.

When winding coils in layers, it is known to first automatically place the winding wire end around the connecting pin to lay and then to wind the coil in a further process step. After the When the coil is wound, the wire end or winding end is automatically wound around the other connecting pin tortuous. For this purpose, the known device has for winding the wire around the connecting pin a winding mechanism consisting of a rotating body with an eccentric to its axis of rotation attached wire guide bore with inserted wire guide tube. After the The rotating body, which is aligned with the connecting pin, is wound in position of the coil in one revolution offset in such a way that the Drahtführungsboferung a rotational movement to the lengthened imaginary Axis of the pin executes. This wraps the winding wire around the connector pin. The connection pins can either be perpendicular or in the direction of the coil axis in the connection flange be introduced into the coil.

In the latter case, the winding mechanism is applied before the terminal pin is wrapped around Pivoted by 90 degrees so that now the connection pin is also parallel to the wire guide tube of the winding mechanism is directed. Wrapping the end of the wire onto the pin of the Flange can thus be done as described above.

In the case of some types of coils, the coil flange has two connection lugs directed parallel to the plane of the flange or solder pins and furthermore in the side of the flange facing away from the coil two, each slots running parallel to a soldering pin. These slots are used to insert and protect the the connecting lugs or soldering pins to be wound on the winding wires of the coil. After wrapping of the connecting wire takes place automatically, there is a technical need to also insert the Connecting wires or the connecting wire automatically closes in the associated slots of the end flange carry out.

The application is based on the task of creating a device of the type mentioned above, by means of which it is possible, before and after completion of the winding of the coil, to also connect the connecting wires to be inserted automatically into the slots made in the front flange. This task is performed according to the Invention achieved in that the winding mandrel or the winding shaft receiving the winding mandrel in a pivot bearing rotatably mounted and the latter around a to the winding spindle and to the axis of rotation of the Wire guide perpendicular axis is pivotable by the angle of a semicircle, such that When the winding coil is pivoted, the wire end to be placed around the connecting pin automatically moves into one associated with the respective connection pin on the side of the coil flange facing away from the coil side introduced slot.

The device created in this way enables the winding ends to be automatically placed in the slots of the end flange and the subsequent winding of the respective coil wire end around the associated Connector pin. Due to the fact that the winding mandrel or the winding shaft is arranged in a pivot bearing is done when pivoting the winding mandrel or the winding shaft by the angle of Semicircle the automatic insertion of the respective coil wire end into the slot of the associated terminal pin.

The device created according to the invention works as follows: First, the automatic one takes place Wrap the beginning of the coil wire around the first soldering pin, then the coil body is in the wire guide plane pivoted around the angle of a semicircle and thereby the coil wire in the former Solder pin associated slot placed in the end flange of the bobbin. After swiveling the The bobbin is coupled to the winding spindle; the coil is wound. Thereupon the bobbin is turned by the angle of a half

circle pivoted back, while the laying takes place carries terminal lugs or solder pins 9 as well as over the of the coil wire end in the end face to the second soldering pin and parallel to the soldering pins Corresponding slot in the end flange of the bobbin. Grooves 10 and 10 '. As in particular from the final page the coil wire end is automatically view of the device according to FIG. 1 can be seen, wrapped around the second solder pin. 5 there is a wire under above the winding device Application of the gebil- guide nozzle 11 according to the invention, which in the direction of arrow 12 to Deten device is made possible, the winding time an axis 13 is rotatable.
