Abstract

PURPOSE:To prevent the loosening of a coil due to the spring back of a wire by applying tension to the wire while being wound, releasing the tension to the wire immediately after wound tightly and holding the side of the coil until immediately before the next wire is wound around the winding region of a core. CONSTITUTION:Rollers 31'-34' are opened, a wire 3 is separated from a track 4 and a solenoid 45 is attracted for driving immediately before the wire is wound around the winding region 22 of a core 20 by passing the gap between a track base 1 and a track cover 2. Links 48, 48' are turned by the force of an extension spring 44 for returning, a pawl 49 recedes and descends and the next wire is wound around the winding region 22 of the core 20. Immediately after winding tightly by applying tension, the attraction of the solenoid 45 is released again and the side of a coil 30 is held by a pawl 39. This prevents the loosening of the coil due to the spring back of the wire 3.

As shown in FIG. 5, the winding of the magnetic helad core 20 is made by passing the wire 3 through the winding hole 21 each time, holding the wire 3 at a predetermined position in the winding part 22, and applying a predetermined tension ( A coil having a predetermined shape is formed by adding a dotted arrow in the figure to the line 6. Here, insert the tip of the wire 3 into the winding hole 21.
When moving to the next winding, it is necessary to release the tension applied to the wire portion, and the wire 3 becomes loose due to the spring bag. As a result, the slackness is transmitted to the wires (coils) already wound around the winding portion 22, and the winding positions are shifted and the alignment of one winding is disturbed.

C. Effects of the invention] As explained above, according to the present invention, immediately after tension is applied to the middle wire of the winding wire and the wire is tightened, the tension on the wire is released, and the next wire is transferred to the winding portion of the core. Since the sides of the coil are held down until just before it is wound, it is possible to prevent the coil from loosening due to springback of the wire, so that a well-aligned winding shape can be maintained. This can contribute to improving the performance of the automatic winding device.
