Abstract

PURPOSE:To prevent abrasion on a particular part on a guide by supporting the guide with a supporting means so as to be rotated around the axis line of a hole for the wire. CONSTITUTION:A guide 16 is a pipe with a hole 26 which guides wire 24 and is supported by a plurality of bearings 28 in a holder 30 to be rotated around the axis line of the guide 16. The hole 26 is penetrated through a guide 16 in the axial direction. Thus, when the wiring is coiled on a bobbin, the guide is rotated around the supporting means in response to the shift of the wire from the guide and the contact position of the wire on the guide is changed. Therefore, the abrasion on a particular part on the guide is prevented.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winding machine for winding an electric wire around a bobbin, and more particularly to a winding machine suitable as a machine for winding an electric wire around a bobbin for a solenoid.

[0002]

2. Description of the Related Art In a winding machine for winding an electric wire around a bobbin, the electric wire is guided to a winding station through a guide having a hole for passing the electric wire, and is wound around the bobbin at the winding station. Winding of the wire on the bobbin is accomplished by rotating the bobbin about its axis and winding the wire onto the bobbin.

However, in the conventional winding machine of this type, since the guide is attached to the supporting means of the guide in a non-displaceable manner, only certain parts of the guide are worn and, as a result, the insulating film of the wire is damaged. Will end up. In particular, like winding machines for solenoids used in relays, when winding a wire around a bobbin, the guide is reciprocally moved together with the supporting means in the axial direction of the bobbin to wind the wire around the bobbin. In a winding machine that changes the position, the insulating film of the electric wire is often damaged due to wear of the guide.

SUMMARY OF THE INVENTION An object of the present invention is to prevent abrasion of only a specific portion of the guide.

[0005]

A winding machine of the present invention is characterized in that a guide is supported by a supporting means so as to be rotatable around an axis of a hole for an electric wire of the guide. When the electric wire is wound around the bobbin, the guide is rotated with respect to the supporting means along with the movement of the electric wire with respect to the guide, and the contact position of the electric wire with the guide is displaced. Therefore, according to the present invention, it is possible to prevent only a specific portion of the guide from being worn.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. 1, a winding machine 10 includes a bobbin 1
A chuck 14 for gripping the wire 2 and a guide 16 for guiding the electric wire to the bobbin 12 are included.

The chuck 14 is attached to the tip of a spindle 18, and the spindle 18 is rotatably supported by a slider 20.
It is slidably supported on the vertical direction. The spindle 18 is rotated around the axis of the spindle 16 by a rotation mechanism (not shown). The slider 20 is moved in the vertical direction by a drive mechanism (not shown).

As shown in FIG. 2, the guide 16 is connected to the electric wire 2.
It has the shape of a cylinder having a hole 26 for guiding 4, and is supported by a holder 30 by a plurality of bearings 28 so as to be rotatable around the axis of the guide 16. The hole 26 is the guide 1
6 through in the axial direction thereof.

Referring again to FIG. 1, the holder 30 is arranged so that the axis of the guide 16 is substantially perpendicular to the axis of the spindle 18, and is displaced in the axial direction of the spindle 18 by a drive mechanism (not shown). And is rotated angularly about the axis of the spindle 18.

As shown in FIG. 3, during winding, the holder 30 is moved toward the spindle 18 to a position where the guide 16 is below the bobbin 12. Then, the tip of the electric wire 24 is locked to the bobbin 12, and in this state, the spindle 18
Is rotated about its axis. As a result, the bobbin 12 is rotated, so that the electric wire 24 is wound around the bobbin 12.

When the electric wire 24 is wound around the bobbin 12, the holder 30 is given a reciprocating linear motion in the axial direction of the spindle 18 and an angular reciprocating rotary motion about the spindle 18 axis. As a result, the winding position of the electric wire 24 around the bobbin 12 changes, and the electric wire 24 is beautifully wound around the bobbin 12.

The guide 16 is slightly rotated with respect to the holder 30 as the electric wire 24 moves due to the reciprocating linear motion and the angular reciprocating rotary motion of the holder 30. Therefore, the contact point of the guide 16 with the electric wire 24 is the holder 3
It changes with a reciprocating linear motion of 0 and an angular reciprocating rotary motion, and as a result, it is prevented that only a specific portion of the guide 16 is worn, and damage to the insulating film of the electric wire 24 is prevented.
