Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a multiple winding method that allows several coils to be obtained simultaneously.

Generally, a high voltage power supply used in an electronic copying machine has a plurality of intermediate taps 3 on the high voltage output winding 2 of a high voltage transformer 1 as shown in Fig. 1 for charging, transferring, neutralizing, and biasing. Obtaining high voltage.

Since the output current of the conductor wound around such a high-voltage transformer 2 is as small as a few mA, the diameter of the wire is 0.05 to 0.06.
Ultra-thin wire such as mm is used.

As shown in Fig. 2, this high-voltage output winding 2 is made by winding an ultra-fine conducting wire 5 around a cylindrical winding frame 4, and when starting winding or pulling out the intermediate tap 3, insulate the winding frame 4 or the conducting wire 5. Paper or insulating tape 6 is pasted, and an auxiliary wire 7 such as a meandering tin-drawn stranded wire is fixed on the insulating paper or insulating tape 6.
A conducting wire 5 was connected to one end of the wire 5 by solder 8, and an interlayer paper 9 was wound thereon for subsequent winding. Then, when the winding is completely completed, the coil is cut into individual coils, and the auxiliary wire 7 is pulled out from the cut surface to obtain a winding start or an intermediate tap.

When providing the auxiliary line 7 in such a configuration, the third
As shown in the figure, since the surface is chevron-shaped, both ends of the upper layer winding are prone to winding collapse.

Therefore, in order to prevent this winding from breaking, a fixing tape is pasted on the other side at the beginning of the winding and at each intermediate tap pull-out portion until the subsequent winding condition becomes somewhat uniform and flat.

For this reason, after fixing the auxiliary wire 7, a large amount of fixing tape is required, and the work of attaching the fixing tape increases, which increases the stop time of the winding machine, resulting in a decrease in operating rate and productivity. Ta.

The present invention eliminates the above-mentioned conventional drawbacks, and aims to provide a multiple winding method that can prevent windings from deforming without using fixing tape even after the part where the auxiliary wire is provided. This is the purpose.

That is, in order to achieve the above object, the present invention provides that both ends of several layers of windings after the part where the auxiliary wire is attached to the winding start and the intermediate tap pull-out part are rough windings, and the rough winding parts are diagonally connected to the upper and lower layers. By intersecting and tightening each other, the windings at both ends are prevented from deforming.

Embodiments of the present invention will be described below with reference to FIGS. 4 to 8.

Reference numeral 10 denotes a long cylindrical winding frame, and around this winding frame 10, a conductor wire 11 made of ultra-fine wire with a linear diameter of 0.05 to 0.06 mm is wound continuously in several coils in a close manner, and an interlayer paper is wrapped around the winding frame 10. The wires are sequentially wound in several layers through 12. An insulating tape 13 is pasted on the certain layer, and an auxiliary wire 14 such as a tin-stranded wire is fixed on the insulating tape 13 in a meandering manner, and a part of the conducting wire 11 is wound around one end of this auxiliary wire 14. It is connected to solder, an insulating paper 15 is wound on top of it, and a conductive wire 11 is wound thereon with a rough winding with a pitch of 1 to 3 mm at both ends. Repeat this several times. At this time, the rough winding wires at both ends intersect diagonally as shown in FIG. 6 and are tightened together, thereby preventing the wires from deforming at both ends. In addition, when winding the conductive wire 11, the interlayer paper 12 for each layer is shaped like the outer shape of the coil, and the cutter 16 is used as shown in FIG.
However, when applying this auxiliary wire 14, cutting of the insulating paper 15 is stopped and the wire is wound on the upper layer before cutting. This prevents the insulating paper 15 and insulating tape 13 from shifting due to the upper layer winding,
The position of the auxiliary wire 14 is kept fixed to prevent wire breakage.

As shown in FIG. 8, the winding machine that roughly winds both ends of the winding is used to change the rotation of the main shaft worm 17 to the close winding traverse rotating shaft 19 or the rough winding traverse rotating shaft 20 by moving the clutch switching rod 18. By switching, close winding can be performed, and the number of rotations decreases during coarse winding, so the fewer layers are used, the better the workability is.

In this way, by rough winding at both ends at the start of winding or within five layers from the part where the intermediate tap is provided, it is possible to prevent the winding from breaking at both ends of the coil when cutting. Of course, at this time, the part where the auxiliary wire 14 is provided becomes chevron-shaped, but the rough winding can prevent the winding from collapsing, and there is no need to apply fixing tape or the like as in the conventional case.

As described above, the multiple winding method of the present invention incorporates an auxiliary wire for the winding start or for drawing out an intermediate tap, and even if the winding on the auxiliary wire becomes mountain-shaped, both ends of the winding in several layers above the auxiliary wire can be used. Since the wires are roughly wound and intersect diagonally at the top and bottom and are tightened together, even if the coils are cut into individual coils, the windings will not collapse at the cut surface, and fixing tape etc. can be used to prevent the windings from collapsing. The winding work is simple, the down time of the winding machine is shortened, and productivity is improved.Furthermore, by adopting rough winding at both ends with a minimum number of layers, the outer diameter of the coil is smaller than that of conventional coils. %, and the winding time can be reduced by 20%, making it of great industrial value.
