CONSTITUTION:An attracting unit 14 like a magnet is provided at a spindle end 12. The spindle end 12 is attracted to the end of a flange 4 of an element 2 to be wound through the unit 14 to fix the end 12 to the element 2 to be wound.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winding method for winding a coiled body such as a coil core or a bobbin on a peripheral surface of the coiled body.

[0002]

2. Description of the Related Art A conventional winding method for a wound body 2 such as a choke coil core will be described with reference to FIG. In this winding method, winding is performed on the peripheral surface 6 of the wound body 2 having the collars 4 at both ends, and one collar 4 of the wound body 2 is wound.
The chuck jig 8 with the chuck jig 8
Is rotated to wind around the peripheral surface 6 (bobbin) between the flanges 2 of the wound body 4.

[0003]

In such a winding method, the flange 4 may be damaged when chucked by the chuck jig 8 if the material to be wound 2 is thin. Therefore, it is necessary to make the thickness of the collar a certain amount as a chuck margin, but if the thickness of the collar becomes thicker, the peripheral surface 6 between the collars becomes narrower and the winding amount is restricted, which is inconvenient. is there.

Further, when one of the collars 4 has a winding terminal 10 as shown in FIG. 6, the winding terminal 10 hinders the chucking of the jig 8 and the collar thickness required for chucking cannot be obtained. Since the workability of the winding is deteriorated, it is necessary to further increase the thickness of the brim.

Therefore, in the present invention, it is possible to mount the winding machine to a required amount by winding it on the winding machine without having to increase the thickness of the collar, and also to mount the winding machine easily. It is an object of the present invention to provide a winding method that can be performed.

[0006]

In order to achieve such an object, in the winding method of the present invention, an adsorbent which can be adsorbed to the end face of the body to be wound is attached to the end of the spindle. Is attached to the end surface of the wound body to fix the spindle to the wound body, and the spindle is rotated in the fixed state to perform winding on the circumferential surface of the wound body.

[0007]

By adsorbing the adsorbent at the end of the spindle to the end face of the body to be wound, the end of the spindle can be fixed to the end of the body to be wound. Therefore, even if there is a flange on the end side of the wound body and the winding terminal is provided on the flange, the spindle end is fixed to the wound body without being disturbed by the winding terminal. Then, the spindle can be rotated to perform winding on the peripheral surface of the winding target.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings.

The winding method of this embodiment will be described with reference to FIG. 1. In this embodiment, an adsorbent 14 such as an electromagnet or a permanent magnet is fixed to the spindle end 12. Then, the flat end surface of the adsorbent 14 fixed to the spindle end 12 is adsorbed to the flat end surface of the collar 4 of the wound body 2 to fix the spindle end 12 to the wound body 2. While the spindle end 12 is rotated in this fixed state, the winding 16 is applied on the peripheral surface 6 between the collars 4 of the wound body 2.
In this case, since it is necessary to attract the magnetic force to the wound body 2, at least one end must be made magnetic.

As described above, in this embodiment, unlike the prior art, the chuck portion of the chuck jig does not chuck the flange of the winding target, so that the chuck needs to be thicker. Moreover, even if a winding terminal is provided on the collar, the winding terminal does not hinder the winding.

In the above embodiment, the spindle end 12 is connected to the collar 4 of the wound body 2 via the attracting body 14 such as a magnet.
Since it is only adsorbed to the end surface of the wire, the tension at the time of winding may act and the spindle end 12 may be displaced from the regular mounting position with respect to the body to be wound 2. Such a recessed portion 18 is provided above and below the end surface of the collar 4 of the wound body 2, or a groove 20 extending vertically is provided on the end surface of the collar 4 as shown in FIG. 3, and further, as shown in FIG. While the rectangular concave portions 22 are provided in the inside and these are used as the engaging portions, respectively, the concave portion 18, 22 and the groove 20 can also be fitted into the suction end 14 side of the spindle end portion 12, respectively. Convex parts 24, 2
It may be possible to prevent the above-mentioned displacement by locking the engaged portion to the engaged portion having a shape of 6 or 28 and engaging the engaged portion with the engaged portion.

Further, in the above embodiment, the spindle end portion 12
Although a magnet is used as the adsorbing body 14 for adsorbing and fixing the magnet to the end face of the collar 4 of the wound body 2, it is not always necessary to use the magnet, and for example, another adsorbing body having a vacuum source at the spindle end 12 may be used. It may be the body. In this case, the wound body 2
The material of is not limited.

[0013]

As described above, according to the present invention, by adsorbing the adsorbent at the end of the spindle to the end face of the body to be wound,
Since the end portion of the spindle is fixed to the end portion of the winding target, even if the winding terminal is provided on the flange of the winding target, the winding terminal is not disturbed by the winding terminal. As a result, it is not necessary to increase the thickness of the collar for chucking with a conventional chucking jig, so that the peripheral surface between the collars can be taken sufficiently and the required amount of winding can be achieved. Even if there is a terminal on the collar, the winding can be done without any hindrance to the terminal, which makes the winding work extremely easy.
