Abstract

PROBLEM TO BE SOLVED: To make it possible to perform high-speed winding, by reducing the weight of a moving body, wherein a winding nozzle, a slider member and a winding main shaft are integrally formed. SOLUTION: A moving body 10 comprising a winding main shaft 1, a winding nozzle 2, a slider member 3 and a weight 9 is guided with a straight advancing guide. The moving body 10 is driven by a motor 5 and a belt 8 for straight travelling and reciprocally moved in the direction of an axial line X. At the same time, the moving body 10 is reciprocally turned around the axial line X by another motor, and a wire is wound around a core 20. Then, the weight 9 is adjusted so that the acting wire L of driving force F by the belt 8 passes the center of gravity G of the moving body 10. The generation of couple of force in the moving body 10 is prevented by the driving force F, and the frictional force with the straight travelling guide is decreased. Thus, the guide part of the slider member 3 is shortened, and the light weight of the moving body 10 is achieved.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stator or a rotating motor for a motor, in which a winding spindle having a winding nozzle for supplying a wire is reciprocated in the axial direction and reciprocally rotated about the axis. The present invention relates to a reciprocating winding device for directly winding a wire around a child core.

[0002]

2. Description of the Related Art Generally, this type of reciprocating winding device is
The winding spindle through which the wire is inserted is reciprocated in the axial direction, and the winding nozzle provided at the tip thereof is inserted into the slot of the stator or rotor core. By reciprocating a predetermined angle around the axis, a wire is supplied from the winding nozzle and wound on each tooth.

In the conventional reciprocating winding apparatus, in order to reciprocate the winding spindle in the axial direction, for example, a slider member is integrally fixed to the winding spindle, and the slider member is attached to the winding spindle. The slider member is reciprocated in the axial direction of the winding spindle by a motor via a ball screw drive mechanism or a belt drive mechanism.

In order to reciprocally rotate the winding spindle around its axis, for example, a spline member is fitted to the winding spindle so as to be slidable in the axial direction and to move in the rotating direction, and the same as above. The main shaft of the winding is reciprocated around the axis by reciprocating the spline member at a predetermined angle by another motor through another belt.

[0005]

However, in such a conventional reciprocating winding apparatus, the position of the driving force for reciprocating and linearly moving the slider member is determined by the positions of the winding nozzle winding main shaft and the slider member. Since the moving member is located away from the center of gravity of the moving member, a couple is generated in the moving member by the application of the driving force in both the ball screw driving and the belt driving. There is a problem that a large frictional force is generated between them.

The only way to reduce the frictional force is to disperse the frictional force by lengthening the sliding contact portion between the slider member and the linear guide. As a result, the slider member becomes large and the weight of the moving body increases. , Not suitable for high-speed winding. Further, the ball screw driven type has a disadvantage that the weight of the moving body is further increased as compared with the belt driven type.
SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and has as its object to provide a reciprocating winding device that enables a high-speed winding by reducing the weight of a moving body.

[0007]

According to the present invention, in order to achieve the above-mentioned object, a winding spindle is formed by integrating a winding nozzle for supplying a wire and a slider member guided by a straight guide. In a reciprocating winding device having a straight driving means for inserting a core of a motor to be reciprocated in an axial direction and a rotation driving means for reciprocatingly rotating about an axis,
A reciprocating winding device in which a weight is mounted on the slider member so that the line of action of the driving force of the linear drive means passes substantially through the center of gravity of a moving body including the winding nozzle, the slider member, and the winding spindle. To provide.

In the above-described reciprocating winding apparatus, it is preferable that the linear driving means drives the slider member linearly via the belt, and the rotary driving means is fitted on the winding main shaft via the belt so as to be relatively non-rotatable. It is preferable that the inserted spline member is driven to rotate. In addition, it is preferable that the linear driving means and the rotary moving means are driven by independent and independent motors.

With the reciprocating winding apparatus according to the present invention configured as described above, the rectilinear driving means drives substantially the center of gravity of the moving body including the winding nozzle, the slider member, and the winding main shaft. Thus, even if the moving body is driven straight in the axial direction of the winding main shaft, no couple occurs in the moving body, and the frictional force generated between the slider member and the straight running guide is reduced. Therefore, the sliding portion between the slider member and the linear guide can be shortened, and the weight of the entire moving body can be reduced.
