Abstract

PURPOSE:To enable a coil to be wound in line by a plurality of layers without a slit which permits a flange to be easily bent by a method wherein while a start line is stored by required length, the start line is wound in an opposite direction of the coil winding each time a coil is wound in line by one layer. CONSTITUTION:On a bobbin 2 storing a start line 3 by required length and mounted on a winding shaft 6, the stored start line 3 is aligned with a flange 21 on the side of the start line 3 and wound one turn in a direction opposite to that of a coil 4 winding each time the coil 4 is wound in line by one layer so that the bobbin 2 is provided with a plurality of layers aligned. For example, the bobbin 2 provided with the flange 2a is mounted on the shaft 6, a starting flyer 8 is fixed to have a winding flyer 7 rotated, the coil 4 is wound in line by one layer on a bobbin bottom 2c, and then turned and wound against a flange 2b. Then, each time the coil 4 is wound by one layer, the starting flyer 8 is rotated to have the start line 3 wound one time along the flange 2a.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a coil winding method for winding an aligned multilayer coil around a bobbin.

[Prior Art] When a coil is wound on a bobbin equipped with a flange, the start wire becomes an obstacle, making it impossible to wind an aligned multilayer coil.For this reason, conventional aligned multilayer coils on a bobbin equipped with a flange are shown in FIG.
As shown in Figure 5, the flange (12a) provided on the bobbin
) to reach the bottom of the bobbin (12d)) (12
c) is provided, and the start H (+3
) is taken out from the bobbin (12) through the slit (+2c), and the coil (14) is wound in an aligned manner layer by layer to form an aligned multilayer coil (11) [Problem to be solved by the invention] In this conventional aligned multilayer coil (11), the bobbin (
The flange (+2a) of 12) is easy to bend due to the slit (12c) provided to pull out the start wire (13), and the more layers the coil (14) has, the more it bends due to the pressure of the winding, so the thickness of the flange (12a) It must be thick.

In addition, the mold for molding the bobbin (12) has a complicated structure because the flange (12a) is provided with a slit (+2c), making the manufacturing of the mold elegant.

This invention is a method for winding in aligned multilayers without providing a slit in the flange provided on the bobbin.

[Means to solve the problem] This first feature will be explained with reference to FIGS. 1 to 3.

FIG. 1 is a perspective view of a bobbin in which coils are wound in aligned multilayers according to the present invention. As shown in Figure 3, this winding is equipped with a shaft (6) for attaching the bobbin of a winding machine (not shown), a flyer on the start side (8), a flyer on the winding side (7), and a flange (2a). ) is attached to the shaft (6), and the start side flyer (8) is attached to the shaft (6).
is fixed, rotate the flyer on the winding side, wind the coil (4) one layer on the bottom of the bobbin (2C) in an aligned manner, and then
At point b), fold back and wind the wire. Each time the coil (4) is wound one layer, the start side flyer (8) is turned, the start wire (3) is aligned with the flange (2a), and the coil (4) is wound once each time.

In this way, each time the coil (4) is wound - layer, the start wire (3
) along the flange (2a) and winding the bobbin one time at a time, or by winding the start wire (3) twice along the flange (2a) while winding the coil (4) in two back and forth layers. As shown in (2), a start wire (3) and a finish wire (5) come out from the outer layer of the coil wound in aligned multilayers.

[Effects of the Invention] According to the present invention, it is possible to wind a coil in multiple layers on a bobbin without having a slit that makes the flange easy to bend. The wire can be pulled out to the required position on the outer layer of the coil.

Further, since the mold for forming the bobbin in which the coil is wound does not have a slit in the flange, the structure is simplified and the moldability of the bobbin is improved.

In addition, the method of winding the coil is to store a large number of start wires, wind the start wire once round and round on one layer wound on the bottom of the bobbin, and then apply the winding wire wound one layer on the bobbin bottom 8B on top of the start wire. Wind it once.

In this way, there is a method in which the start wire and the winding wire are alternately wound one round and the other, and the start wire and finish wire are taken out from the upper layer of the coil.
