As shown in FIG. 1, the winding apparatus of this embodiment has a winding mechanism 1 (winding means) for winding the wire 100 around a mold 10 (mold body) and a welding mechanism 2 (welding means). )
A cutting mechanism 3 (cutting means), a conveyance and insertion mechanism 4 (conveyance and insertion means), and a control device 5 for controlling these mechanisms.
This winding device is used by being mounted on a frame 210 arranged near the conveyor 200.

It has a rotating body 11 that can rotate around the central axis of the mold 10 just below 0, and a rotating arm 12 having a plurality of guide rollers 13 is fixed to the upper surface of this rotating body 11. On the other hand, on the supply side of the wire rod 100, wire rod supply guide rollers 14, 14 are provided, and the wire rod 100 wound around these wire rod supply guide rollers 14, 14 is inserted into the center hole 11 a of the rotating body 11. Then, it can be wound around the guide roller (second clamp) 13 and guided to the wire rod clamp (first clamp) 15. The wire rod clamp 15 holds the tip of the wire rod 100 led out from the guide roller 13 of the rotary arm 12, and moves up and down under the control of the actuator 16. Further, a pulley 17a is attached to the lower part of the rotating body 11, and the power of the drive motor 19 is transmitted to the rotating body 11 via the belt 18 and the pulley 17b.

The winding of the wire 100 on the mold (mold body) 10 by the winding mechanism 1 is performed by a so-called flyer winding method. That is, the drive motor 19 is operated to drive the pulley 17b and the belt 1.

Further, when a detection signal indicating that the short ring (work) is not wound around the mold 10 is received from the laser sensors 50 and 51, a function of turning on the warning lamp 52 and stopping the operation of each mechanism is provided. Have

Next, the operation of this embodiment will be described.
FIG. 12 is a flowchart showing the operation of the winding device of this embodiment. As shown in FIG. 12, this operation includes a winding process A, a welding process B, a cutting process C, a conveyance process, and an insertion process D. Each process includes welding with the winding mechanism 1 controlled by the controller 5. The mechanism 2, the cutting mechanism 3, the conveyance, and the insertion mechanism 4 are sequentially achieved.

In the winding step A, first, as shown in FIG. 1, the mold 10 of the inserter 4-1 is placed at the winding position W, and in this state, as shown in FIG. Wire rod 100
Is wound around the wire feed guide rollers 14 and 14 and inserted into the center hole 11a of the rotating body 11, and then is wound around the guide roller 13 of the rotating arm 12 and the tip end thereof is held by the wire clamp 15 to prepare for winding. Perform (step S1 of FIG. 12). After that, when the drive motor 19 is started,
The pulley 17b rotates, the pulley 17a rotates via the belt 18, and the rotating arm 12 rotates with the rotating body 11 around the central axis of the mold 10 (step S2 in FIG. 12). As a result, the wire rod 100 is wound around the mold 10, and the wire rod clamp 15 is raised by the control of the actuator 16 before the rotary arm 12 comes into contact with the stretched portion 100a of the wire rod 100 (steps S3 and S4 in FIG. 12). ). Then, at the time when the rotating arm 12 passes so as to cross the lower side of the tensioned portion 100a,
The wire rod clamp 15 is lowered, and the winding start and winding end portions of the wire rod 100 are overlapped with each other, so that the wire rod joining portion 100b.
One winding 100c (see FIG. 5) having
Is formed (step S5 in FIG. 12). After the winding process A is completed, the process proceeds to the next welding process B.

In the welding step B, the actuators 20a, 20b, 20c of the welding mechanism 2 shown in FIG. 3 are activated, and as shown in FIG. 5, the horn 23 of the welder 21 is connected to the wire rod joining portion 100b side of the die 10. Be moved to. Then, as shown in FIG. 6, the wire rod joining portion 100b of the winding body 100c is pressed by the step portion of the horn tip portion 24 and the anvil 10a of the mold 10 (step S in FIG. 12).
6). Then, the horn 2 is attached to the wire-bonding portion 100b.
The torsional vibration of No. 3 is applied, and the wire rod joint portion 100b is welded (step S7 in FIG. 12). At this time, the wire-bonding portion 10 sandwiched between the horn tip portion 24 and the anvil 10a.
Since the tooth-shaped unevenness 24a bites into 0b, there is no displacement of the wire rod joint portion 100b during vibration, and as a result, the torsional vibration of the horn 23 is efficiently transmitted to the wire rod joint portion 100b. After the welding process B is completed, the welder 21 is returned to the original position and moved to the next cutting process C.

In the cutting step C, the actuator 36 of the cutting mechanism 3 shown in FIG.

Is activated, and the supply wire rod portion 100d and the stretched portion 100a are respectively clamped by the wire rod clamps 32a and 32b (step S9 in FIG. 12). Thereafter, as shown in FIG. 9B, the wire rod clamps 32a and 32b are moved rearward by the actuators 34 and 35, and the extended portion from the wire rod joint portion 100b is pulled. Then, as shown in FIG. 9C, the actuator 31
a and 31b are actuated, portions on both sides of the wire rod joint portion 100b are cut by the cutters 30a and 30b, and the short ring 100e is produced in the die 10 (step S10 in FIG. 12). That is, when the wire rod clamps 32a and 32b pull the supply wire rod portion 100d and the stretched portion 100a in the direction away from the mold 10 (see (b) of FIG. 9), the angle between the blade of the cutter and the wire rod becomes large, As a result, both ends of the wire rod joining portion 100b can be cut by the cutters 30a and 30b. After the wire rod is cut, the clamped state between the wire rod clamp 32b and the wire rod clamp 15 is released, and the end material of the stretched portion 100a held by the wire rod clamp 32b and the wire rod clamp 15 is discharged. On the other hand, the end portion of the wire rod 100a held by the wire rod clamp 32a is transferred to the clamp 15.
(Step S11 of FIG. 12). By delivering this wire, preparation for the next winding is made. After the cutting process C is completed, the process is moved to the next carrying and inserting process D.

When the mold 10 of the insertion machine 4-1 reaches the insertion position I, first, the laser sensor 50 shown in FIG.
51, the short ring 100 in the mold 10
The presence or absence of e is confirmed. When the short ring 100e is not present in the mold 10, a detection signal indicating that is present in the control device 5
The warning light 52 is turned on by the control device 5 and the subsequent operation is stopped. When the short ring 100e is in the mold 10, the core 201 on the conveyor 200 is lifted up integrally with the core jig 202 by the actuator 203, and as shown by the chain double-dashed line in FIG. Is positioned directly below the mold 10, and the subsequent insertion work is performed.

That is, as shown in FIG.
The actuator 44 drives the pusher 43 with the center pin 10b inserted in the center hole of the core 201. As a result, as shown in FIG. 11B, the arm 10g of the ejector 10c is pushed down by the pusher 43, and the ring press portion 10e is pushed downward. As a result, the short ring 100e is pushed out of the mold 10 and the short ring groove 201a of the core 201 is pushed out.
The wire rod 100 is press-fitted inside and the insertion of the wire 100 into the core 201 is completed (step S13 in FIG. 12). Short ring 10
After the insertion of 0e, as shown in (c) of FIG. 11, the pressing force of the pusher 43 to the arm 10g is released,
The ejector 10c is returned to the inside of the mold body by the biasing force of the coil spring 10d. In parallel with this, the core jig 20
2 is pulled down to the original position by the actuator 203, and the core 201 in which the short ring 100e is inserted
Are placed on the conveyor 200.

In the state where the insertion machine 4-1 is in the insertion position I as described above, the insertion machine 4-2 on the opposite side is in the winding position W. Winding preparation is performed. That is, as shown in FIG. 9D, the cutters 30a and 30b of the cutting mechanism 3 and the wire rod clamp 32 are provided.
The whole a and 32b move to the wire rod clamp 15 side, and the wire rod clamp 32a advances to the wire rod clamp 15 side. Then, after the wire rod clamp 32a causes the wire rod clamp 15 to hold the distal end portion of the sandwiched supply wire rod portion 100d,
Release the clamped state. After that, the cutters 30a, 30
b and the wire rod clamps 32a and 32b are returned to their original positions, and the work of all steps is completed (step S in FIG. 12).
14).

Thereafter, the operations of steps S2 to S14 of FIG. 12 are repeated, and as shown in FIG. 1, the core 201 having the short ring inserted therein is sequentially manufactured, and is conveyed to the next step by the conveyor 200. .

As described above, according to the winding device of this embodiment, after the short ring 100e is manufactured by the winding mechanism 1, the welding mechanism 2 and the cutting mechanism 3, the short ring 10e is formed.
Since the short ring 100e can be continuously conveyed and inserted by the conveying / inserting mechanism 4 without stocking 0e, the rotary transformer can be assembled in a short time, and as a result, the productivity can be improved. It is possible to improve. Further, the short ring 100e is automatically produced by the winding mechanism 1, the welding mechanism 2, and the cutting mechanism 3, and the produced short ring 100e is automatically produced by the transporting and inserting mechanism 4 in the short ring groove 2 of the core 201.
Since it can be inserted into 01a, not only the efficiency and labor saving of the rotary transformer production can be achieved, but also the short ring 100e is deformed or the short ring groove 201a is insufficiently pushed in the insertion process. As a result, a rotary transformer of high quality and high precision can be provided.

In the present embodiment, the work to be wound is the short ring of the rotary transformer, but it goes without saying that it can be applied to other similar works without departing from the spirit of the present invention.
