no. 1 Embodiment approach

[0013] Referring to FIG. 1 , a wire winding device 100 according to a first embodiment of the present invention will be described. FIG. 1 is a perspective view showing a winding device 100 .

[0014] The winding device 100 is a device for manufacturing a coil by winding the wire 3 supplied from the wire supply source 2 around a winding core (coil reel) 11 that rotates around the axis center line.

[0015] The winding device 100 includes: a winding machine 10 that drives the winding core 11 to rotate around the shaft center line; the wire 3 supplied from the wire supply source 2 is supplied to the wire payout machine 20 on the winding core 11; A tensioning device 15 for the tension of the wire 3 of the winding machine 10; a controller 70 for controlling the winding action.

[0016] The winding core 11 is composed of a trunk portion 11a around which the wire 3 is wound, and flange portions 11b provided on both end surfaces of the trunk portion 11a to regulate the winding width ...

no. 2 Embodiment approach

[0065] Referring to FIG. 3 , a winding device 200 according to a second embodiment of the present invention will be described. FIG. 3 is a perspective view showing the winding device 200 .

[0066] The same reference numerals are assigned to the same configurations of the wire winding device 200 of the present embodiment as those of the wire winding device 100 of the first embodiment described above, and description thereof will be omitted. Hereinafter, it demonstrates centering on the difference from the winding device 100.

[0067] The difference between the bobbin winding device 200 and the bobbin winding device 100 of the above-mentioned first embodiment is that the partial structure of the tension device 15 is different.

[0068] In the tensioning device 15 of the winding device 100 of the above-mentioned first embodiment, by controlling the rotation speed of the variable wire speed motor 17, the linear speed of the wire 3 fed out from the pulley 16 is changed, and the s...

Abstract

The invention provides a winding device, a tension device and a winding method. A winding device 100 which winds a wire 3 around a core 11 includes the core 11, which rotates axially and around which the wire 3 is wound; a roller 21 which rotates axially and feeds the wire 3, which is wound around the roller 21, to the core 11; and a tension device 15 which adjusts a tension of the wire 3 that is supplied to the core 11 from the roller 21. A winding shape and a winding diameter of the wire 3 wound around the roller 21 are substantially identical to a winding shape and a winding diameter of the wire 3 wound around the core 11.

Description

technical field [0001] The invention relates to a winding device, a tensioning device and a winding method. Background technique [0002] As a conventional tensioning device included in a winding device for forming a coil, the following device is known: the tension of the wire supplied to the winding machine is detected, and the detected value controls the rotation speed of the pay-out roller that successively pays out the wire, and the wire The tension remains constant. (Refer to JP-A-11-222357 and JP-A-2000-128433). [0003] However, in such a conventional tensioning device, when winding a core having a different diameter with a different cross-sectional outer diameter, for example, a core having a rectangular cross-sectional shape, the tension cycle of the wire during one rotation of the core is Sexually change. Therefore, there is a problem that it is difficult to keep constant the tension of the wire rod sent to the winding machine. Contents of the invention [00...
