Abstract

PURPOSE:To make shuttling operations needless by a method wherein a core holder is shuttled synchronously with shifting of an endless belt between two rollers to be wound around by a wire piercing through a central part of core. CONSTITUTION:A belt 2 and a wire passing through a long hole of a joint 3 are pierced through the central part of a ring type magnetic core 6 fixed to a core holder 4 after removing the joint 3 therefrom to fix one end of the wire to a wire chuck 5. Then rollers 1, 1' are turned to apply tension to a corner A of magnetic core 6 by the wire. Next, when the holder 4 synchronized with the joint 3 is shifted to a point Y, the wire in length by half round of core 6 is drawn out to apply tension to another corner B of core 6. Later when the wire outside a conical roller 1' is drawn back by the second wire chuck 8, tension is applied to the other corner C of core 6 so that tension may be applied to the other corner D of core 6 by successive reversing of belt 2 to wind the wire. around the core 6. Finally, the holder 4 and the joint 3 are synchronously shifted in the reverse direction to be restored to their original status.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a winding machine for winding magnet wire or the like around a ring-shaped magnetic core.

<Conventional technology> A conventional shuttle-type winding machine that winds a ring-shaped magnetic core to create a toroidal coil is
Pass the shuttle through the ring-shaped magnetic core, wind the wire into the shuttle, store the wire, and apply tension to the wire when starting the 9-winding operation.

The shuttle required a certain degree of rigidity. Therefore, the inner diameter of the magnetic core and the length of the wire that can be wound naturally are limited for each shuttle.

However, in this type of winding machine, if the inner diameter of the magnetic core is small, the winding will be difficult. There were drawbacks such as easy contact, poor top-up of one roll, and poor quality.

The present invention eliminates such drawbacks of the conventional method and includes a belt 2 that is made endless by a joint 3 that spans two rollers 1tl' having grooves carved on the outer periphery, and a belt 2 that is made endless by a joint 3. A core holder part 4 is provided along the belt 2, which holds a magnetic core through which a long winding wire passes through the center hole, and reciprocates between two rollers provided with a wire chuck 5 for fixing one end of the wire. , and a second wire chuck 8 for applying tension to the wire is provided on the outer periphery of one roller 1'.

Effect> When the core holder is moved in synchronization with the rotation of the belt, the wire is wound around the magnetic core near the roller, so the wire is wound each time the core holder moves back and forth.

<Embodiment> As shown in FIG. 1, the embodiment of the winding machine of the present invention consists of a ring-shaped magnetic core 6 held by a core chuck 7 of a core holder section 4 provided with a wire chuck 5 for holding the starting end of the wire. A belt 2 extending over two rollers 1.1' runs through the center. A second wire chuck 8 is also provided which rotates on the outside of one of the rollers 1' and applies tension to the wire. The belts are connected endlessly by a belt joint 3 having a long length extending through the belt. As shown in FIG. 2, this roller 1 has V-shaped grooves carved on the outer peripheral surface of the roller.

A belt 2 having a trapezoidal cross section is driven through this groove, and a wire is passed through the gap at the bottom of the groove to form a winding machine.

Now, as shown in FIG. 3, remove belt joint 3f.

The belt 2 is passed through the center of the magnetic core 6 set in the core chuck 7 of the core holder part 4, the belt joint 3 is connected again, and the roller 1 is wrapped around it to make it endless. Further, the wire is passed through the long hole of the joint 3, and one end is fixed to the wire chuck 5, and the wire is cut to the full length of the two windings. Initially, the core holder section 4 is stopped at the left end point X. When the belt 2 is rotated, the wire is applied to the corner A of the magnetic core 6 in FIG. The core holder part 4 moves together with the magnetic core 6 in synchronization with the joint 3 so that the wire reaches the right end point Y until the maximum length t of the wire is pulled out. At point Y, the wire for half the circumference of the magnetic core 6 is pulled out, and tension is applied to the corner p of the magnetic core 6 in FIG. Thereafter, the second wire chuck 8 grasps the wire protruding from the cone b-ra l' and pulls the wire back between A and B.

At this time, tension is applied to cross section No. 1 of the magnetic core 6 in FIG. Then, while the elongated hole in joint 3 of belt 2 goes from B to C, the wire is pulled out by t2.

Tension is applied to the two corners of the cross section of the magnetic core 6 in FIG.

When the joint 3 reaches C, the core holder part 4 is moved in synchronization with the belt 2 so as to bring the wire length t3 to the X end, and tension is applied while drawing out half the wire at the X point. While the core chuck 7 is shifted by one pitch in the circumferential direction of the magnetic core 5, the belt joint 3 is wound one turn each time the belt joint 3 makes one revolution. Joint 3 when the winding is finished
A coil is formed by removing the wire.

Effects of the invention> As described above, according to the invention, there is no limit to the inner diameter of the ring-shaped magnetic core using the shuttle unlike in the past, and it is possible to wind a considerable number of wires even on a magnetic core with a small inner diameter. Can also be used with traditional shuttle method
