Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toroidal coil winding machine used for winding a wire around a core, and more particularly to a toroidal coil which can select an appropriate winding speed according to the wire diameter and the core diameter. Regarding winding machines.

[0002]

2. Description of the Related Art Heretofore, a toroidal coil winding machine for winding a core with a wire has been known. The toroidal coil winding machine includes a storage ring and a shuttle ring which are rotatably arranged in a plane perpendicular to a ring-shaped core on which a wire is wound and which penetrate an inner diameter of the core. In such a toroidal coil winding machine, the wire that is stored in the storage ring so that it can be paid out is wound around the core while being drawn out by the shuttle ring.

[0003]

When the core is wound using the wire, the wire accumulated in the accumulator ring is routed to the shuttle ring. Is not an appropriate ratio, the tension applied to the wire during winding varies greatly. For this reason, when the shuttle ring is rotated at a high speed, deterioration of the wire is promoted, and eventually the wire may be broken. FIG. 8 shows the relationship between the wire diameter (wire diameter) and the maximum allowable tension when the core is wound by the toroidal coil winding machine, and the shuttle ring diameter with respect to the core diameter when the winding speed is used as a parameter. It is a graph showing the relationship between the ratio of and the tension acting on the wire. In FIG. 8, for example, the maximum allowable tension (load) of a wire material diameter (wire diameter) having a diameter of 0.4 mm is about 960 g (see intersection point a in the figure). High winding speed 100R
When using PM, winding speed 100R from the intersection point a
When the intersection is found in the graph of PM (see the intersection b in the figure) and the ratio of the shuttle ring diameter to the core diameter is obtained from the intersection b, the intersection c in the figure is obtained, and the ratio of the shuttle ring diameter to the core diameter is about 1.8. You know what you have to do below.

As can be seen from the above description, when winding the core, if the winding speed is increased, the ratio of the shuttle ring diameter to the core diameter is limited. By the way, since the diameter of the core on which the winding is wound is fixed, if the ratio of the shuttle ring diameter to the core diameter is limited, the shuttle ring diameter is also limited. Therefore, the conventional toroidal coil winding machine is a low-speed winding machine as a general-purpose machine that can be used even when the wire diameter and the core diameter are different, and a dedicated machine that is used only for a predetermined wire diameter and core diameter. High-speed winding machine. In the conventional toroidal coil winding machine, either the high-speed winding machine or the low-speed winding machine, the shuttle ring diameter is substantially the same as the accumulator ring diameter and is constant. In the conventional toroidal coil winding machine, a high-speed winding machine as a dedicated machine can be applied only to a predetermined one having a limited core diameter and a wire diameter, and a low-speed winding machine as a general-purpose machine has a winding speed. There was a problem that is slow.

In view of the above-mentioned circumstances, the present invention has an object to be described below (B1). (B1) In a toroidal coil winding machine, even if the core diameter and the wire diameter are different, the winding can be performed at high speed.

The core 1 is held by a holding member (not shown) in a plane including the paper surface in FIG. 1, and in a plane extending in the left and right directions perpendicular to the paper surface in FIG. A shuttle ring 2 arranged in a plane perpendicular to the plane in which the core 1 is arranged (a plane extending in the left-right direction perpendicular to the paper surface in FIG. 1) penetrates the core 1. Originally, this shuttle ring 2 is divided into two parts, but when used, it is shown in FIGS.
As shown in FIG. 1, the core 1 is assembled and used in a ring shape in a state of penetrating the core 1. Also, this shuttle ring 2
As shown in FIGS. 1, 3 and 6, the driven gear 2 is provided on the upper peripheral portion.

1 is arranged in a plane parallel to the plane in which it is arranged (in a plane extending in the left-right direction perpendicular to the plane of FIG. 1).
2 has a shape in which one side of a quadrangle is partially cut off, as shown in FIG. The core 1 is arranged perpendicular to the shuttle ring guide roller support member 4 at the cut portion. The shuttle ring guide roller support member 4 has a plurality of elongated holes 6 extending radially. The elongated holes 6 include a plurality of rotatable shuttle ring outer peripheral guide rollers 7 that guide the outer periphery of the shuttle ring 1 (see FIGS. 2 and 3), and a plurality of rotatable shuttles that guide the inner periphery of the shuttle ring 1. This is for mounting the inner ring guide roller 8 (see FIGS. 2 and 3) so that the position can be adjusted.

Since the shuttle ring outer circumference guide roller 7 and the shuttle ring inner circumference guide roller 8 have substantially the same structure, the shuttle ring inner circumference guide roller 8 will be described mainly with reference to FIGS. As shown in FIG. 6, the shuttle ring inner peripheral guide roller 8 has a pair of upper and lower flanges which are arranged so as to sandwich the guided projection 2b from above and below. A roller support shaft 9 for supporting the shuttle ring inner peripheral guide roller 8 is provided at a long hole fitting portion 9a having an outer diameter for fitting in the long hole 6 and an upper end of the long hole fitting portion 9a. It has a small diameter screw portion 9b, a large diameter flange portion 9c provided at the lower end of the long hole fitting portion 9a, and a small diameter roller support portion 9d provided at the lower end of the large diameter flange portion 9c. The shuttle ring inner peripheral guide roller 8 is rotatably supported by a roller support portion 9d at the lower end of the roller support shaft 9 via a bearing (not shown). A nut 10 with a seat is screwed onto the small-diameter screw portion 9b at the upper end of the roller support shaft 9. When the seated nut 10 is loosened, the roller support shaft 9 can move along the elongated hole 6, and when the seated nut 10 is tightened, the roller support shaft 9 is fixed at that position.

The shuttle ring outer peripheral guide roller 7 also has a pair of upper and lower flanges (not shown) similar to the shuttle ring inner peripheral guide roller 8, and the flanges vertically move the driven gear 2a of the shuttle ring 2. It is arranged so as to be sandwiched between. Similar to the shuttle ring inner peripheral guide roller 8, the shuttle ring outer peripheral guide roller 7 is also rotatable by the roller support shaft 9 and the seated nut 10 and is positionally adjustable along the elongated hole 6.

As can be seen from FIGS. 1, 2, 3 and 6, one of the plural elongated holes 6 is rotated by a shuttle ring drive motor 12 instead of the shuttle ring outer peripheral guide roller 7. A driven shuttle ring drive gear 13 is arranged so that its position can be adjusted. The shuttle ring drive gear 13 meshes with the driven gear 2a of the shuttle ring 2 to rotate the shuttle ring 2. In FIG. 6, a motor support member 14 that supports the shuttle ring drive motor 12 includes a motor support base 14a, a long hole through cylinder 14b extending downward from the motor support base 14a and penetrating the long hole 6, and a length of the long cylinder. It has a large-diameter flange portion 14c provided at the lower end of the hole penetrating cylinder 14b.

A male screw is provided on the outer peripheral portion thereof. A female screw of the tightening handle 16 is screwed onto the male screw of the elongated hole through cylinder 14b. When the tightening handle 16 is tightened, the shuttle ring guide roller support member 4 is tightened from above and below by the tightening handle 16 and the large-diameter flange portion 14c. At this time, the motor support member 14 is fixed to the shuttle ring guide roller support member 4. Further, when the tightening handle 16 is loosened, the motor support member 14 can move along the elongated hole 6.

As described above, the mounting positions of the shuttle ring outer peripheral guide roller 7, the shuttle ring inner peripheral guide roller 8, and the shuttle ring drive gear 13 can be adjusted on the shuttle ring guide roller supporting member 4. , The shuttle ring rotation supporting device 3 is
Even shuttle rings 2 having different sizes (outer diameters) can be rotatably supported.

Next, the storage line ring 21 and the storage line ring rotation support device 22 will be described mainly with reference to FIGS. A storage line ring 21 arranged in a plane perpendicular to the plane in which the core 1 is arranged (a plane extending in the left-right direction perpendicular to the paper surface in FIG. 1) penetrates the core 1.
Like the shuttle ring 2, the storage line 21 is originally divided into two parts, but when used, it is formed into a ring shape while penetrating the core 1 as shown in FIGS. It is assembled and used. As shown in FIG. 7, the storage line ring 21 is provided with a wire accommodating portion 21a in the upper outer peripheral portion and a driven gear 21b in the central portion of the inner peripheral portion.
Is provided. The storage line ring 21 is rotatably supported by a storage line ring rotation support device 22. The storage line rotation support device 22 has a flat storage line guide roller support member 23. The storage ring guide roller support member 23 is arranged in a plane parallel to the plane in which the storage ring 21 is arranged (a plane extending in the left-right direction perpendicular to the paper surface in FIG. 1). The flat plate-shaped accumulating ring guide roller support member 23 is shown in FIG.
As shown in FIG. 3, one side of the quadrilateral is partially cut off. Then, the core 1 is arranged perpendicular to the accumulating ring guide roller supporting member 23 at the cut portion. The accumulator ring guide roller support member 23 guides the outer circumference of the accumulator ring 21 by a plurality of rotatable accumulator ring outer circumference guide rollers 27 (see FIG. 4) and the inner circumference of the accumulator ring 1. This is for mounting a plurality of rotatable storage line inner circumference guide rollers 28 (see FIG. 4) and a storage line ring drive device for rotationally driving the storage line ring 21.

The storage line inner circumference guide roller 28 is constructed in substantially the same manner as the shuttle ring inner circumference guide roller 8, and therefore its explanation is omitted. Since the storage wire ring outer peripheral guide roller 27 needs to pull out the wire from the wire accommodating portion 21a above the outer peripheral portion of the storage wire ring 21,
It is different from the shuttle ring outer peripheral guide roller 7. As can be seen from FIG. 7, the storage line outer peripheral guide roller 27 has a flange portion 27a that supports the lower surface of the storage line ring 21 and a cylindrical guide portion 27b provided above the flange portion 27a.

The storage ring outer peripheral guide roller 27 is
A roller support shaft 29 (see FIG. 7) supported by the accumulator ring guide roller support member 23 is rotatably supported by a bearing (not shown) on the upper end thereof. Further, the storage line inner circumference guide roller 28 is also supported on the storage line ring guide roller support member 23 in the same manner as the storage line outer circumference guide roller 27.

As can be seen from FIGS. 1 and 4, the storage ring driving guide wheel supporting member 23 has a storage ring driving gear 3 which is rotationally driven by a storage ring driving motor 31.
2 are arranged. The accumulator ring drive gear 32 meshes with the driven gear 21b of the accumulator ring 21 to rotate the accumulator ring 21. In FIG. 7, the storage line driving motor 31 is attached to the lower surface of the storage ring guide roller support member 23,
The output shaft 31a is connected to the clutch 33. The storage ring driving gear 32 is mounted on the output shaft 33a of the clutch 33. The clutch 33 stores a wire from a bobbin (not shown) to the wire storage ring 21,
The output shafts 33a and 32a are connected to transmit the driving force of the storage ring drive motor 31 to the storage ring drive gear 32, and when the core 1 is wound, the storage ring 21 is set in a half-clutch state. This is to prevent the idle rotation of the.

1, 5 and 6, guides 36 and 37 for pulling out the wire W (see FIG. 5) from the storage wire ring 21 when the shuttle ring 2 is rotated to wind the core 1. (See FIGS. 1, 5 and 6) is supported on the lower surface of the shuttle ring 2. In FIG. 5, the portion of the shuttle ring 2 that supports the guides 36 and 37 is broken, so the guides 36 and 37 are
Although it seems to be supported on the upper surface, it is actually supported on the lower surface of the shuttle ring. The wire W accommodated in the wire accommodating portion 21a of the power storage ring 21 is guided by the guides 36 and 37 to a position between the upper surface of the power storage ring 21 and the lower surface of the shuttle ring 2. On the lower surface of the shuttle ring 2, a wire roller 38 (see FIGS. 5 and 6) that circulates the wire W guided by the guides 36 and 37 is rotatably supported. Then, as can be seen from FIG. 5, the tip of the wire W is fixed to the core 1.

[Operation of Embodiment] Next, the operation of the toroidal coil winding machine of the embodiment having the above-described configuration will be described.
First, the core 1, the shuttle ring 2, and the storage ring 2
1 is held in the state shown in FIG. Next, the wire storage ring drive motor 31 is driven to wind the wire W from the bobbin (not shown) onto the wire housing portion 21a of the wire storage ring 21 to store the wire. Next, the wire housing portion 2 of the storage ring 21
The wire W stored in 1a is pulled out to guide the guide 3
The tip of the wire W is fixed to the core 1 by being guided by 6, 37 and the wire roller 38. When the shuttle ring drive motor 12 is driven in this state, the shuttle ring 2 rotates, and the core 1 is wound. At that time, the core 1 is rotated at a predetermined speed, so that the core 1 is uniformly wound. The above operation is the same as the conventional one.

When the wire diameter or the core diameter is changed, the shuttle ring 2 having an appropriate diameter capable of high speed winding obtained from the graph shown in FIG. 8 is replaced. At that time, the shuttle ring drive motor 12, the shuttle ring outer peripheral guide roller 7, and the shuttle ring inner peripheral guide roller 8 are moved and adjusted along the elongated hole 6 to rotate a new shuttle ring 2 having a different diameter. It can be drivably supported. Then, the shuttle ring 2 is rotated at a high speed within a possible range to perform high speed winding. That is, the toroidal coil winding machine of the above-described embodiment can perform high-speed winding work on the core by using shuttle rings having different outer diameters. That is, as can be seen from FIG. 8, when the wire diameter (wire diameter) and the core diameter change,
Although the shuttle ring diameter for performing high-speed winding is different, the winding work can be performed by exchanging with a shuttle ring having a different diameter in this embodiment, so that even if the wire material diameter (wire diameter) and the core diameter are changed. High-speed winding can be performed.

[Modifications] The embodiments of the present invention have been described in detail above, but the present invention is not limited to the above-mentioned embodiments, and is within the scope of the gist of the present invention described in the claims. Thus, it is possible to make various small design changes.

For example, it is possible to dispose a wire guide roller on the upper surface of the storage line ring 21. Also,
The shuttle ring inner circumference guide roller 8 and the shuttle ring outer circumference guide roller 7 are fixed by fixing a plurality of bolt tightening screw holes provided on the shuttle ring guide roller support member 4 and their screws according to the diameter type of the shuttle ring 2. It is also possible to use a bolt for fixing the roller supporting member in the hole. Further, the mounting positions of the storage line outer peripheral guide roller 27 and the storage line inner peripheral guide roller 28 can be adjusted, and the storage line rings 21 having different diameters can be exchanged and used.

[0025]

Since the toroidal coil winding machine of the present invention described above can perform winding using shuttle rings having different diameters, even when the core diameter and the wire diameter are changed, the wire at the time of winding can be changed. Keeping such tension below a certain level, without causing wire deterioration or disconnection during winding,
High-speed winding work can be performed.
