Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for continuously winding a coil.

There are two types of winding methods in the winding device: a method in which the coil winding shaft itself is rotated, and a flyer type in which the winding shaft is fixed and the conducting wire is rotated and wound.

The present invention is based on the former method in which the winding shaft itself is rotated to wind it. Conventionally, in the method of rotating the winding shaft, for example, in a voice coil for a speaker or a choke coil, the winding start and winding end are pulled out from the coil body. If it is necessary to shape the coil body or leader wire using adhesive, etc., it is necessary to fix one end of the leader wire to the winding shaft and to ensure that the winding wire is wound closely to the winding shaft. The only way to fix one end of the conductor as a wire is to manually wrap it around a stopper fixed to the winding shaft, and it is also necessary to keep the end of the winding fixed as the adhesive for any shape solidifies. As a result, work efficiency was poor and mass productivity was poor.

The present invention automates the conventional manual work of winding and fixing lead wires, and to explain this with reference to the embodiment shown in the drawings, bearings 13 are placed on the base plate 4 at equal intervals.
A plurality of bearings 131C are arranged to hold the winding shaft 1 of each bearing 131C.

A winding shaft 1 is integrally equipped with a winding shaft 2 that clamps and holds a conducting wire 7, and a winding shaft 3 is attached to a base plate 4 and arranged between the winding shafts. There is.

b is the coil winding station, and a and c are the stations one before and one after, respectively.

At station a, the bobbin has already been inserted into the winding shaft 1a, and when the conductor I from the wire reel 22 is clamped onto the pick shaft 2b of station b and the machine is started, the base plate 4 is fed one station. , the winding shaft 1a'v at station a and the biting shaft 2a13a are at station bK.
The winding shaft 1b is moved one by one, and the shafts 2b and 3b are moved to station C.
These become the s-socket shafts 2c and 3c.

Next, the cam device 10 operates in this state, and when the roller 9 is on the convex portion of the cam device 10, the push plate 8 and the shaft 2b
, 3b are pushed up, and the conducting wire 7 comes into contact with the central shafts 5, 5'.

Next, when the roller 9 comes to the flat part of the cam device 10, the push plate 8 is moved closer to the base plate 4 by the spring 20 suspended from the base plate 4.

crimped to the push plate 8 by springs 21, 21';
The central axes 5, 5' of the hook shafts 2b, 3b move downward, the heads of the middle no-pongee 5, 5' are crimped onto the heads of the receiving shafts 6, 6', and the conductor I is inserted into the hook 1. is maintained securely.

At this point, the conductor I is connected to the wire reel 221, starting from the single shaft 2C, from the single shafts 3b and 2b, closely contacting a part of the outer peripheral surface of the bobbin of the winding shaft 1b. .

Next, the cutter 11 approaches and picks up the conductor I and the shaft 2b.
However, the conductive wire I is still held between the grip shafts 2b and 3b.

Next, when the tapered head 12 with a flange is moved downward and inserted into the four parts of the winding shaft 1b, the winding shaft 1b
F-The inserted bobbin is fixed.

The cone clutches 14 and 15 are engaged, and the rotation of the motor 19 is transmitted to the winding shaft 1b by the electromagnetic clutch brake 17 and 18, and the coil is wound.

At this time, since the lifting shaft 2b is fixed to the winding shaft 1b, it rotates around the 11th winding shaft 1b which integrally holds one end (winding start end) of the conductor I, so that The conductor I is wound around.

At this time, winding is performed while applying the adhesive for any shape as required.

In this way, when the required number of turns is reached, the winding shaft 1b is stopped at a fixed position by the electromagnetic clutch brakes 17 and 18, and the coil winding is completed.

At this time, the knob shaft 2b comes to a position above the push plate 8 and stops.

Next, the cone clutches 14 and 15 are disengaged, the taper head 12 and the cutter 11 return to their original positions, and the base plate 4 is once again fed one station. Move to position 1 of the next station C and newly create the winding shaft 1c, the winding shaft 1c, and the winding shaft 2c, 3c.
becomes.

Since the conducting wire 7 is moved by the station c1 which is held by holding the conducting wire 7 on the shaft 2b, the conducting wire 7 starts from the knob shaft 2c again at this point, passes through the coil part of the winding shaft 1c, and moves to a new terminal. It is spread between the shafts 2b and 3b, and the winding shaft 1
The wire reel 221 is in close contact with a part of the outer peripheral surface of the bobbin b.
becomes connected.

Then, winding can be repeated in the same steps as described above.

In the present invention, as described above, in a winding device that rotates the winding shaft itself, the conducting wire I from the wire reel 22, the start and end of winding of the coil are held by the winding shafts 2b and 3b,
This is a winding device that can automatically and continuously wind a coil, greatly improving work efficiency.
