Problems solved by technology

In particular, since the wound coil has inertia at the end of the winding, it sometimes causes a large swing or vibration when it is sent out to a predetermined length or when it is bent and rotated, and the winding cannot be performed. , in order to ensure a stable coil shape, it is also necessary to reduce the winding speed

Embodiment Construction

[0032] Hereinafter, an edgewise coil winding method and a winding device for forming an edgewise coil (hereinafter, may be simply referred to as a "coil") in the present invention will be described based on one embodiment. figure 1 It is a perspective view of an edgewise coil winding device to which the present invention is applied.

[0033] figure 1 Among them, the prolate coil winding device 1 has: a bending unit 10, which uses a main clamp 11 and a bending mechanism 12 to hold the flat wire 3, and bend it into a predetermined angle such as 90 degrees; The unit 30, wherein the frame-shaped flat wire 3 is sequentially bent by the bending unit 10 to be rolled into a frame shape, and changes shape in a plane along with the bending action of the bending unit 10 .

[0034] In addition, a pressing unit 70 is provided, which clamps the flat wire 3 sent out to the bending unit 10 on the upstream side of sending out the flat wire 3 to the bending unit 10, thereby preventing the flat...

Abstract

The invention provides a winding method of an edgewise coil and a bobbin winder suitable for a coil being capable of keeping completion of winding. The winding method of an edgewise coil adopts a pivot part of a main plate (11) used as a joggling machine and a bending mechanism (12) to keep a bent part of a flat wire (3) that is conveyed by a given length; enables the bending mechanism (12) to rotate around the pivot part when a supply side of the flat wire (3) connected with the joggling machine is fixed; then bends the kept flat wire (3) to form the edgewise coil (4). An inner periphery side or an outer periphery side of the edgewise coil (4) is buckled with a coil guider (31). The coil guider (31) is moved following movement of the edgewise coil (4) driven by a submission action of the flat wire (3), and the coil guider (31) is rotated side to side following movement of the edgewise coil (4) driven by rotation side to side of the joggling action.

Description

technical field [0001] The present invention relates to an edgewise coil winding method and a winding device for longitudinally winding a flat wire, and more particularly to an edgewise coil winding method and a winding device for avoiding the disorder (vibration in the axial and radial directions) of the winding coil . Background technique [0002] Conventionally, there has been proposed an edgewise coil winding device which sequentially bends a flat wire having a rectangular cross-section (wound in the width direction) in order to improve the utilization efficiency of the winding space when the coated copper wire is wound into a coil shape. flat wire) and longitudinally wound to form an edgewise coil (see Patent Document 1). [0003] In this device, the flat wire drawn out according to the specified length is clamped by the supporting roller rotating in the center of the shaft and the bending mechanism arranged on the outer periphery of the supporting roller, and the bend...
