Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a toroidal winding machine.

[Conventional technology]

As shown in FIGS. 10 and 11, a conventional toroidal winding machine has drive rollers 2 and 3 and driven rollers that are arranged at a predetermined position on the outer circumference of a donut-shaped workpiece 1 and rotate the workpiece 1. The roller 4 is arranged so that its ribs are perpendicular to the donut-shaped workpiece 1, and has a rotatable wire storage ring 6 in which a thin wire 5 to be wound around the workpiece 1 is stored. And the wire storage ring 6, the donut shaped wire
The wire 1 is rotated, and the thin wire 5 drawn out from the wire storage ring 6 is wound around the doughnut-shaped workpiece 1, thereby performing toroidal winding. Regarding this, Japanese Patent Application Laid-Open No. 54-398
There is a publication No. 59.

That is, the workpiece 1 and the wire storage ring 6 are rotated to wind the thin wire 5 on the workpiece 1, and the thin wire 5 pulled out from the wire storage ring 6 is passed through the slider 7 and the slider 7 provided on the circumference of the wire storage ring 6. 1 on the workpiece 1 through the brake plate 8°9
It rotates (see FIGS. 11(a) to 11(d)) and is wound.

That is, the counterclockwise rotation of the rotary roller 10 provided on the inner periphery of the wire storage ring 6 rotates the wire storage ring 6 in the same direction.

The rotation of the workpiece 1 is 1 by clockwise rotation of the drive rollers 2 and 3.
It rotates counterclockwise, and this interlocking and continuous operation creates a toroidal winding around the entire circumference of the workpiece. A plurality of lead wires 11 (see FIGS. 10 and 11 (e)) are formed on the winding thus wound.

[Problems to be Solved by the Invention] The above-mentioned prior art does not give consideration to the treatment of the lead wire generated during winding. In other words, for toroidal windings that require a lead wire, when the lead wire comes under the wire storage ring, the work and wire storage ring must be temporarily stopped to prevent the lead wire from being crushed by being wound with thin wire. After the worker bends the lead wire by hand and passes it under the wire storage ring, the workpiece and wire storage ring are rotated again to start winding, but as the number of rises of each lead wire increases, The number of cycles of stopping and avoiding 9 exit lines and starting the machine increased, making it difficult to operate one-on-one between humans and machines.

The present invention has been made in view of the above points, and an object of the present invention is to provide a toroidal winding machine that is capable of continuously winding a wire until the end of winding.

[Means for solving problems]

The above object is achieved by providing a winding device in the single winding machine that allows the lead wire of the thin wire to be wound and formed on the workpiece to be wound without hitting the wire storage ring and the thin wire drawn out from the wire storage ring. , achieved.

[Effect]

The winding machine is equipped with a winding means that allows the lead wire of the thin wire to be wound and formed on the workpiece to be wound without hitting the wire storage ring and the thin wire drawn out from the wire storage ring, making it a single winding machine. Since the lead wire is wound without hitting the wire storage ring or the thin wire, there is no need to stop the winding machine every time to avoid the lead wire as in the past, and the wire can be wound continuously until the end of winding. It can be wound using wires.

Next, the functions of this toroidal winding machine will be explained. As mentioned above, the arm unit has a four-axis drive function of elevating and lowering, moving back and forth nine times to the left and right, and turning. In the lifting operation, the rotation of the motor 17 rotates the screw shaft 18 via the motor shaft 17a.

As a result, the upper base 21 integrated with the screw plate 23 moves up and down using the rails 20.degree. 20a as orbits. In the left-right operation, the rotation of the motor 27 rotates the screw shaft 28 via the motor shaft 27a. As a result, the plate 30, which is integral with the screw plate 46, moves left and right on the rails 24, 24a. The forward and backward movement is performed by rotating the screw shaft 35 via the motor shaft 34a by the rotation of the motor 34. As a result, the slide plate 37 that is integrated with the screw plate 38 is attached to the rail 31.
, 31a as orbits to move back and forth. In the turning operation, the rotation of the actuator 40 is caused by the motor shaft 40a and the guide shaft 42.
, flange 42a, nut 45. Although the description has been made regarding the 0 or more right arm unit which rotates the right arm 13 by 90 degrees via the chuck 44, the left arm unit also has the same function.

Next, in the case of a workpiece in which there are many lead wires at the time of 0 winding, which will be explained about the operation, the lead wires 11 are automatically moved from the right to the left of the wire storage ring 6 as shown in FIG. 1 above. This is done by a combination of the left and right arm units. In other words, in front of the wire storage ring 6 in the direction of one rotation of the workpiece, the sensor 14 senses the output wire 11 of the rotating workpiece 1 and determines its position. Check. At the same time, when the motor 34 of the right arm unit shown in FIG. 2 rotates clockwise, the arm 13 moves forward, and at the same time, the motor 27 rotates counterclockwise to move the arm 13 to the right. During this time, the arm 13 also turns 90 degrees and the workpiece 1 Exit line 1 with the rotation of
Wait for 1 to come.

Figure 1 (A) shows a state in which the base of the rotating lead wire 11 is caught on the right arm 13, and Figure 1 (B) shows a state in which the lead wire 11 is stopped by pulse control after sensing. ing. That is, the clockwise rotation of the motor 17 is caused by the motor shaft 17a, the screw shaft 18. The upper base 21 is raised via the screw plate 23, and the right arm 13 is raised. This right arm 13 extends from the base of the lead wire 11 toward the upper end, and stores the end of the lead wire therein. During this time, the workpiece 1 rotates, so use the right arm 13 to turn the lead wire 11 to the right, as shown in Figure 1 (b), and wrap the thin wire around the base of the first winding without slipping even if it hits the wire. Can be done. The lead line 11 of the stopped workpiece 1 is connected to the left arm 12 as shown in Fig. 1 (b).
moves forward and laterally and grabs the base of exit line 11. right arm 1
At this point, the right arm 13 turns 90' and separates from the exit line 11, as shown in Figure 1 (c).
After turning and waiting for the next exit line 11, the left arm 12 retreats and becomes as shown in Fig. 1 (D).In this way, the transfer of the left and right arms 12 and 13 of the exit line 11 is completed, and the exit line 11 is moved back. The wire 11 is automatically passed under the wire storage ring 6 and is wound again from FIG. This repeated automatic operation made it possible to automate one winding. That is, the position of the output line 11 is confirmed by the sensor 14, and the output line 11 is captured at the tip of the right arm 13.
The root of the lead wire 11 is captured in consideration of the fall of the lead wire 11. Then, the tip of the right arm 13 that caught the root rises by rising! Since the lead wire 11 is formed so that the lead wire 11 is traced from the root to the tip, the lead wire 11 can be stably housed within the tip of the arm. Then, the left arm 12 grasps the base of the lead wire 11 that has raised the right arm 13, and at the same time, the right arm 13 is removed from the lead wire 11, and at the same time, the left arm 12 is raised and retreated on the lead wire 11. During the transfer operation, the output wire 11 under the wire storage ring 6
The automatic transfer and avoidance operation were ensured.

In this way, according to this embodiment, since the lead wire can be automatically avoided, it is possible to automate toroidal winding, and it is possible to shift the one-on-one work system between the toroidal winding machine and the worker to a system where multiple machines can be operated simultaneously. was completed.

〔Effect of the invention〕

As described above, the present invention enables continuous winding until the end of the winding, thereby providing a toroidal winding machine that can continuously wind the wire until the end of the winding.
