Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a toroidal winding device for continuously winding a wire around a toroidal core in both forward and reverse directions.

[Background technology]

Conventional toroidal winding devices include those using a slider system and those using a system including a single winding ring and a storage ring. With both of the above methods, the wire can be wound only in one direction, which is the same direction or the opposite direction to the ring rotation direction during wire storage. Therefore, in order to wind the same toroidal core with different G wire directions, first wind the wire in the same direction, cut the -#: wire, and then re-wind the G wire in the same direction.
Store +ti in the opposite direction to that described above and wind the wire in the opposite direction to that described above.

Finally, all the cut parts are connected manually to complete the winding.

Therefore, winding the wire around the toroidal core in both the forward and reverse directions using the conventional apparatus described above not only results in poor winding efficiency, but also in that the IC pole material is wasted and the wire connection area is There is a slight drawback that the presence of such a material deteriorates the FW airtime characteristics.

For the purpose of eliminating the defects in the bidirectional winding of the conventional device It, a device disclosed, for example, in Japanese Patent Application Laid-open No. 39859/1983 has been proposed. The equipment section is.

2fj is equipped with a wire storage ring and a winding ring and drives both rings separately! It has a structure with 1 kimono and 1 kimono. The winding 1717 is driven when the wire is wound in the opposite direction to the wire storage direction of the wire storage ring, and the wire storage ring is driven when the wire is stored and when the wire is wound in the same direction as the wire storage direction. , when either ring is driven, resistance is applied to the other ring by the brake. However, in this device, there is a risk that the wire may break when the storage g1 side is fully driven to wind the wire, and no means for solving this problem are disclosed.

[Purpose of the invention]

The small gears 40 and 100 are both rotatably fitted onto a fixed shaft 28 whose both ends are fixedly supported by the upper movable frame 21.

The torque control device 22 has a function of connecting the wire storage ring 1 and the wire winding ring 5 via small gears 4D and 10Dt so as to generate idle torque. That is,
The configuration of the control device is such that the rotating shaft 23 is rotatably supported within the casing 27 as described above, the rotating disk 29 is locked to the rotating shaft 23 located within the casing, and both sides of the rotating disk are Permanent magnet disks 30 and 30 are placed opposite the surfaces, respectively.
B f (: Arranged. As shown in FIG. 3, the permanent magnet disks are magnetized with N and 8 poles alternately and equally divided in the circumferential direction. Permanent magnet disk 30A is fixedly installed on the inner wall of the casing 27, and the permanent magnet disk 30B is installed on the inner wall of the casing 27 so as to be rotatable in the circumferential direction by a renoise 31 shown in FIG. 30B is rotated and adjusted so that the two discs with the same polarity overlap (the state shown in Figure 3), a repulsive force is generated between the two discs, and the rotating disc 29 located at the center of the two discs becomes It can rotate freely. - 10,000, Reno - When the two discs with different polarities are overlapped by 31, an attractive force is generated between the two discs, and the rotation of the rotating disc 29 is restrained. .Therefore, by adjusting the angle to the east of the poles of both discs using Reno-31, the two-handed gear 4D
, IOD, that is, the wire storage ring 1 and the wire winding ring 5 can be connected so as to generate idle torque.

In addition, 32 in the figure is a toroidal core (schematic shape) on which windings are made in both forward and reverse directions.

Next, the operation of the winding device of the present invention configured as described above will be explained.

The toroidal core 32 is held by a holder equipped with an indexing device (not shown), and is placed across the wire storage ring 11 and the winding ring 5 as shown in FIG. 2 (the placement method will be described later). . Next.

The end of the wire rod is pulled out from a wire storage section (not shown) disposed near the winding device, and is placed in the notch 3 of the wire storage ring 1. In this state, the electromagnetic clutch 13 is energized, and the armature 14 and rotor 15t are magnetically attracted to each other. Next, when the motor 19 is driven counterclockwise (looking from the right side in FIG. 1, the same applies in the following explanation), the transmission belt 18%, the pulley 1f, the rotating shaft 12, the rotor 15. Armature 14
．． The wire storage ring 1 is driven and rotated clockwise through the small gear 4A'lk, and the wire rod is stored in the wire storage ring. When the required number of legs have been stored, stop the motor and! magnetic latch 1
Release 3 and cut ~ material. Next, the cut end of the wire rod winding on the side of the g storage ring is connected to the guide wall 7 of the winding ring 5.
It is passed through a guide pipe 8A fixedly attached to the guide pipe 8A, and further passed between guide pulleys 9A and 9B to be locked to the complete toroidal core 32. Next, when the motor 19 is driven clockwise, the transmission belt 18, the gear 91, the rotating shaft 12. The winding ring 5 rotates counterclockwise by C through the small gear 10A, and winds the toroid core in the opposite direction (counterclockwise). ! (state shown in Figure 4). It is pulled by the Ivji material being paid out by the counterclockwise rotation of the winding ring.

Rotate in the direction. At this time, if the wire storage ring rotates more than necessary due to its own inertia without being pulled by the winding ring, the winding tension of the toroidal core may decrease or the winding tension may become uneven.

However, in the device of the present invention, there is no such fear due to the function of the torque control device 22. That is, the wire storage ring 1 is connected to the winding ring 5 via the pinion 10D, the torque control device 22, and the pinion 4D, and is rotated in the counterclockwise direction 1 (driving rotation) in the same direction as the winding ring 5. .

At this time, a magnetic slip is applied by the torque control device 22, that is, an idling torque is generated, and the wire storage ring 1 is driven to rotate at a slower speed than the winding 1 section ring 5. Therefore, since the wire storage ring 1 is actually rotating at a higher speed than the winding ring 5, this driving force acts as a brake, and the wire storage ring 1 always rotates to follow the winding ring. Therefore, an appropriate winding tension is ensured. As described above, the permanent magnet disk 30B of the torque control ill device 22 is rotated by the magnet 31, and the disk 301
By generating an appropriate magnetic force between the rotating disk 2 and the opposing permanent magnet disk 30A, the rotating disk 2 located at the center of both disks is
By partially restraining the rotation of the rotating disk 29, that is, by applying slip, an idling torque is generated, and the rotation of the rotating disk 29° and the rotating shaft 23. This is done by causing a rotational delay in the storage ring 1 via the small gear 411.

The initial winding in the positive direction is completed by a slight angle rotation of the toroidal core by the index device (not shown) or a reciprocating motion applied thereto. When the winding in the forward direction is completed, the toroidal core is rotated by a predetermined angle by the indexing device, and the winding in the primary direction is performed in the reverse direction.

Winding in the opposite direction is performed by rotating the motor 19'ff counterclockwise to drive and rotate the winding ring 5 clockwise (the state shown in FIG. 5). When winding in the opposite direction,
If the storage ring 1 is stopped with respect to the winding ring 5 which is driven and rotated, no tension is applied to the wire and proper winding cannot be performed. )
Since it is driven by the winding ring 5 via the device 22, there is no need to worry about this. That is, the wire storage ring 1 is rotated at a lower rotation speed than the first winding ring 5 due to generation of idling torque.

Apply appropriate tension to the wire being wound.

As mentioned above, in this example device, a device using permanent magnetic force is used as a torque control device that connects the wire storage ring and the winding ring so as to generate idling torque, so electric power is required to operate the device. The effect is that the required amount of idling torque can be easily set with 'S2, and the device structure is very simple and there is almost no risk of failure.

In the above embodiment, the wire storage ring is driven and rotated clockwise to store the wire, but it is also possible to drive and rotate the ring counterclockwise to move it to the needle side. In this case, when winding f1, the entire wire is inserted into the guide pipe 8B instead of the guide nose 8A.

Therefore, if the needle side direction is always limited to one direction during operation, the guide pipe of -10,000 can be omitted.

Further, in the above embodiment, after one clockwise winding, the forward winding was performed first, but it is also possible to perform the reverse winding first. Furthermore, even when winding is done in the counterclockwise direction, winding can be started from either the forward or reverse direction.

As explained above, the torque control device is positive.

In winding # in the direction of rain flow, both are provided to give a positive tension to the wire. However, with the winding in the forward direction, it is used as a braking device to slow down the rotation of the storage ring, and with the winding in the reverse direction, it is used as a driving force transmission device to actively rotate the storage ring. Therefore, the required rotational torques of the forward winding and the reverse winding generally do not match. However, each required idle torque loss is not determined as a constant value, but has a certain range t in relation to the tensile strength of the wire. In general, in the case of a thick material having a high tensile strength, lJ is large and there is a range in which the required torque between the two is partially equal, and thus it is possible to wind the wire in a good manner by using the apparatus of the above-described embodiment.

In cases where there is no range in which the required torque values of both 4 and 1 match, or where more uniform winding is desired, two torque control devices 111 and 22 are provided as shown in FIG. , the present invention may be implemented as a device configuration in which different idling torque amounts are set for each winding direction, and switching is possible by the clutch 43 depending on the winding direction.

Next, another embodiment of the torque control device will be described with reference to FIGS. 7 to 9.

Fig. 7 shows an example in which an electromagnetic clutch is applied to the torque control device 22a. Furthermore, a small gear 35a has a disk 35'a fixed on one side facing the small gear 35a with a small gap therebetween.
It has a low-cost configuration that allows it to rotate. The small gear 34a
, 35a mesh with the winding ring 5 and the wire storage ring 1, respectively. The coil is excited via the low brush 36a, and the turning torque is set depending on the magnitude of the electromagnetic force.

The mechanism of this example is effective in preventing breakage of the thin wire material and making the winding iron uniform. That is, in the case of this embodiment, since it is based on the tension force, it can be controlled in a drowsy manner by connecting it to a cutting device so as to obtain the optimum (constant) tension for the force.

FIG. 8 shows an example using the torque control device 22bVc pneumatic pressure, in which a fixed shaft 3 whose both ends are fixedly supported by a fixed frame 21 is shown.
3b is bored with an air circulation hole 37b, one end of the hole 37b communicates with an air circulation pipe (not shown) at the end of the fixed shaft 33b, and the other end is open to the outer periphery of the fixed shaft 33b.
b is rotatably fitted to the fixed shaft 33b, and a cylinder chamber is formed inside thereof, and a portion of the cylinder chamber communicates with an opening bored in the inner circumferential wall of the small gear 35b.

A piston member 38b is fitted into the cylinder chamber.

The small gear 34b is rotatably fitted into the fixed IM 33b. In addition, in the figure, 39b and 39b are air seal rings, and the space between the air circulation hole opening opened on the outer periphery of the fixed shaft 33b and the opening bored in the inner circumferential wall of the small gear 35b is defined as a nitriding space. It is provided for. The small gears 34b and 35b mesh with the winding, IJ IJ song, and wire storage ring 1, respectively. In the case of this example, all the air flows into the cylinder chamber and the piston member 38b' is pressed against the side wall of the small gear 34b with an appropriate pressure, and the amount of idling torque is set by adjusting the air pressure. It has the effect of lowering costs.

FIG. 9 shows an example in which a compression spring is used in the torque control device 22c, and the compression force of the compression spring 40c is adjusted by pressing the adjustment plate 42ci with the adjustment port 41c. 34c. In this example, the idle torque class is set by adjusting the compression force of the compression spring. As mentioned above, this has the effect of lowering costs.

〔Effect of the invention〕

Since it is equipped with a torque control device that connects the wire storage ring and the winding, IQ and IJ rings so as to generate a full torque, it is possible to perform winding in both forward and reverse directions evenly, and it is a simple device. This has the effect of being possible due to the Ling configuration.
