Description

Winding machine for layer-by-layer two-thread winding of electrical coils - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -The invention relates a winding machine for winding electrical coils with two-strand parallel winding by a rotating thread guide. If you use a normal winding machine revolving thread guide for two-thread winding, so are the wound wires twisted and there is no perfect parallel winding. This becomes the number of turns based on the. Available winding space compared to a normal winding reduced In a winding machine according to the invention is through sensible arrangement of the wire feed andd: through appropriate training the winding body receptacle prevents twisting of the wires0 This is according to the invention achieved in that on the axis of the bobbin holder with the thread guide synchronously rotating second thread guide is arranged, through which the direction of movement the opposite direction of the first wire, the second wire the first thread guide The basic structure of such a winding machine should be based on an exemplary embodiment will be explained in more detail. The bobbin-5 in the schematic diagram is attached to a plate-shaped transport body 6 at the beginning of the winding process the transport body 6 is pushed into the guide rails of the lap holder 7 and locked. The first wire 2 is withdrawn from the supply roll 1 overhead, through the first thread guide 3 and out of the bore 12 to the bobbin 5 led. The second wire 13 is guided in a similar manner by means of an overflow pot take-off from the supply roll 11 through the hollow shaft 10 and the second thread guide 14 to the bore 12 of the first thread guide 3 and from there to the bobbin 5. This Arrangement is expediently chosen if the two wire beginnings are on one common soldering point and the two wire ends also on another common Solder terminal should be created 0 A second feed option creates the requirement that # each wire beginning or each wire end at separate soldering terminals can be attached. In this case the first wire becomes 2- through the bore 4 of the first thread guide 3 and the second wire 13 through the bore 12 of the first thread guide 3 is guided to the bobbin 5.

The shaft of the first thread guide 3 and the shaft 16 of the second thread guide 14 are driven synchronously by a drive, not shown. The winding take-up 7. is mounted on the shaft 10 via a ball bearing. The shaft 10 is hollow in the executed shaft 16 of the second thread guide 14 in the directions 19 and 20 displaceable0 The winding receptacle is affected by the frictional forces of the ball bearing and the winding tension 7 a torque in the direction of rotation of the first and second thread guides (3 and 14). This torque would result in a relative movement of the coil body 5 in relation to it the thread guides result. The torque can be counteracted by because # the center of gravity of the lap holder 7 is placed as low as possible by weights 15 will. Another solution is to use magnets instead of the weights 15 when out of reach of the second thread guide 14 more Magnets interact with those attached to the winding receptacle 7.
