Abstract

PURPOSE:To dispense with passing a wire through a nozzle and improve working and truing-up properties, by using a wire guide and a traversing pin. CONSTITUTION:A copper wire 4 is held on a part of a bobbin 2. A winding motor 3 is started to begin to wind the wire 4 around the bobbin 2. A traversing motor 8 is rotated synchronously with the winding motor 3. A wire guide 7 and a traversing pin 5, which are mounted on a plate 6, move the copper wire 4 for a prescribed pitch while guiding it, so that the wire is wound in a trued- up state. The traversed pitch is set equal to the finished outside diameter of the copper wire 4. When the diameter of the wire is changed, the wire can be wound in a trued-up state only by modifying the traversed pitch.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an aligned winding method for manufacturing coils, transformers, etc. by a winding shaft rotation method, and uses a traverse pin and a wire guide to facilitate lead wire processing work. , the purpose is to improve alignment.

As shown in FIG. 4, the conventional aligned winding method uses a nozzle 12 in which the wire 13 is free in the flow direction of the wire and restricted in the hole diameter direction, so the wire 13 must be passed through the nozzle 12. However, the workability is poor, and the alignment is disturbed due to the clearance between the inner diameter of the nozzle and the wire.

The present invention solves the above-mentioned conventional drawbacks, and embodiments thereof will be described below with reference to FIGS. 1 to 3.

In Figures 1 to 3, a winding shaft holding a 1Fi pobbin 2, 3 a winding motor that drives this winding shaft 1, and 8 a traverse motor that drives a ball screw 9 in synchronization with the winding motor 3. a motor; 11 is a slide block that is fed at a fixed pitch by a ball screw 9; 6 is the slide block 1;
A plate 1 is held; 5 is a traverse pin held by the plate 6 for winding the copper wire 4 onto the bobbin 2 in an aligned manner; and 7 is a traverse pin for winding the bobbin 2 in order to bring the copper wire 4 into close contact with the traverse pin 5. A line guide 1o that maintains a constant inclination angle θ with respect to the starting point and the extension line of the traverse pin 6 is a detent pin for preventing rotation of the slide block 11.

With the above configuration, the copper wire 4 is held in a part of the bobbin 2, and the winding of the copper wire 4 on the bobbin 2 is started by starting the winding motor 3. The traverse motor 8 starts rotating in synchronization with the wire winding motor 3, and the wire guide 7 and traverse pin 6 held on the plate 6 guide the copper wire 4 and feed it at a constant pitch to align it. Start winding.

The traverse pitch is set to be the same as the finished outer diameter of the copper wire 4, and if the wire diameter changes, aligned winding can be achieved by simply adjusting the traverse pitch.

Therefore, there is no need to pass the copper wire through the nozzle, improving workability, easily adapting to changes in wire diameter, and contributing to high-mix, low-volume production.

In FIG. 2, the positional relationship between the driver pin 6 and the wire guide 7 is such that the wire guide 7 position is determined so that the copper wire 4 can be brought into close contact with the driver 5 (-spin 6).
The line guide 7 position is the winding start point of the bobbin 2, and the inclination angle with respect to the extension line of the traverse pin 6 is 30°〉θ〉1o
0, and the wire guide 7 has a snail shape as shown in FIG. 1 to facilitate the threading of the wire.

In the above embodiments, a ball screw is used as the traverse mechanism, but a cam may be used as the traverse mechanism, as long as the line guide and the traverse pin move at a constant speed.

As described above, according to the present invention, by using the wire guide and the traverse pin, the need to pass the wire through the nozzle is eliminated.
However, it improves workability and lineability, and can easily respond to changes in wire diameter, making it effective for high-mix, low-volume production.
