This reciprocating shaft 12 is configured to reciprocate in its axial direction. The stroke amount of this reciprocating movement can be set arbitrarily, and the amount of movement of the rotary shaft 10 per rotation can also be set to a predetermined value in synchronization with the rotation of the rotary shaft 10. There is.

As shown in FIG. 7, the reciprocating shaft 12 is provided with a mounting member 14.
A guide device 100 is attached to. The guide device 100 is configured such that a guide member 102, which is made by folding felt material into two and can hold a conducting wire 16 between them, can be attached to a mounting member 14 using a pair of brackets 104.

is configured to guide the conducting wire 16 so that it can be wound around the bobbin 1.

[0005]

[Problems to be Solved by the Invention] However, in such a conventional device, two conductive wires 16 are connected to one bobbin 1.
In order to simultaneously wind the two conductive wires 16, the two conductive wires 16 are sandwiched between the guide member 102 and guided to the bobbin 1.The conductive wires 16 rub against each other within the guide member 102, and the plating of the conductive wires 16 is peeled off, causing insulation. was sometimes incomplete. Furthermore, if the strength with which the conductor wire 16 is held between the guide members 102 differs, the friction between the guide member 102 and the conductor wire 16 will increase or decrease, the tension of the conductor wire 16 will change, and the tension between the two conductor wires will change. The resistance values of both coils are
There were different cases. Furthermore, the guide member 102
Depending on the degree of wear, the tension may change and be adversely affected. In this way, in the conventional
If two conductive wires 16 are wound at the same time, a product may be created in which the insulation is incomplete or the resistance values of both coils are different, resulting in a problem that the reliability of the device may be lacking.

Moreover, when removing the bobbin 1 after winding and installing a new bobbin 1, the conducting wire 16 tends to come off from the guide member 102, and the guide member 102
If the two conductive wires 16 are twisted or turned upside down, it may become difficult to tell which conductive wire 16 belongs. Furthermore, since the shape of the guide member 102 is large, it is difficult to bring the guide member 102 and the bobbin 1 close to each other, and there is a problem that workability is not necessarily good.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a winding machine that guides two conductive wires so that the reliability and workability can be improved and the two conductive wires can be appropriately wound around a bobbin. The object of the present invention is to provide a guide device for

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view of a guide device for a winding machine, which is an embodiment of the present invention. 1 is a bobbin, bobbin 1 is
A cylindrical body part 2, a collar part 4 provided at both ends of the body part 2,
6, and three terminal insertion portions 8 are formed in one of the collar portions 4 so as to protrude beyond the collar portion 4 in the radial direction.

The bobbin 1 is configured to be removably attached to the rotating shaft 10 so as to be coaxial with the rotating shaft 10, and the rotating shaft 10 is rotationally driven by a drive source (not shown). ing. Further, a reciprocating shaft 12 is arranged parallel to and spaced apart from the rotating shaft 10 by a predetermined distance. As is well known, the reciprocating shaft 12 is driven to reciprocate in its axial direction, and is configured such that its reciprocating stroke amount can be adjusted. Furthermore, one of the rotating shafts 10
The amount of movement of the reciprocating shaft 12 per rotation can also be adjusted.

A mounting member 14 is inserted into the reciprocating shaft 12, and the mounting member 14 is moved along the axial direction of the reciprocating shaft 12 to manually adjust the position at which winding onto the bobbin 1 begins. Further, an adjustment mechanism (not shown) is provided which rotates around the reciprocating shaft 12 to change the mounting angle and manually adjusts the diameter of the bobbin 1.

On the other hand, the conducting wire 16 before being wound around the bobbin 1
As shown in FIG. 6, the lead wire 16 is wound around a spool 106, and the lead wire 16 is pulled out from the spool 106 via a pull-out mechanism 108 that pulls out the lead wire 16 without tangling it. In this embodiment, this spool 1
06 and the drawer mechanism 108 are placed side by side.

Two nozzles 20 each having a guide hole 18 through which the conducting wire 16 can pass are provided, and as shown in FIG. 3, in this embodiment, the nozzle 20 has a thick base and a thin tip. A ruby guide 22 through which the conducting wire 16 can pass is attached to the tip thereof. This nozzle 20 is fitted into two insertion holes 26 formed at predetermined intervals in the axial direction of a cylindrical rotating member 24, respectively. Further, the tip of the nozzle 20 is bent inward so that both ruby guides 22 are brought closer to each other.

In this embodiment, both insertion holes 26 are formed on a straight line passing through the center of the rotating member 24 and at equal distances on both sides of the center of the rotating member 24. There is. Also, the center of both insertion holes 26 and the rotating member 24
A mark line 25 passing through the center of is drawn on the rotating member 24.

The rotating member 24 has a large diameter hole 28 which is connected to both insertion holes 26, and a ceramic guide 30 is fitted into the large diameter hole 28. This ceramic guide 30 has an insertion hole 32 formed in its axial direction.

The rotating member 24 is rotatably inserted into a sliding hole 36 formed in the swinging member 34. The swinging member 34 is provided with a
A screw hole 38 connected to the sliding hole 36 is formed, and a screw 40 is screwed into this screw hole 38. This screw 4
The rotation of the rotating member 24 can be restricted by rotating the screw 40 to enter the screw hole 38 and pressing the tip of the screw 40 against the rotating member 24.

In this embodiment, the screw hole 38 and the screw 40
The first regulating mechanism 42 is configured by the first regulating mechanism 42 . The first regulating mechanism 42 is not limited to such a configuration, and may have any configuration as long as it can regulate the rotation of the rotating member 24 and release the regulation. For example, it may be a split mold in which the sliding hole 36 is divided into two in the axial direction to tighten the rotating member 24, or a collet chuck.

Incidentally, on the swinging member 34, a scale 44 is drawn at every 10 degrees around the sliding hole 36. A through hole 46 is bored in the swing member 34 in a direction perpendicular to the sliding hole 36, as shown in FIG. One end of the swinging member 34 is inserted into a groove 50 formed in the arm member 48.
It is fitted so that it can swing. This arm member 48 includes
An insertion hole 52 having the same diameter as the through hole 46 is formed perpendicularly to the groove 50, and the groove 50 is formed concentrically with the insertion hole 52.
A screw hole 54 is formed on the opposite side.

Furthermore, a set screw 58 having a male threaded portion 56 that can be screwed into this screw hole 54 is provided, and this set screw 58 has the following features:
It has a swing shaft part 60 connected to the male thread part 56 and insertable into the through hole 46 and the insertion hole 52, and a large diameter part 62 connected to the swing shaft part 60. Further, a knob portion 64 is formed in connection with the large diameter portion 62 .

Then, the swinging shaft 60 is inserted into the through hole 46 and the insertion hole 52, and the male threaded part 56 is screwed into the screw hole 54, so that the swinging member 34 is inserted into the swinging shaft 60. It is supported so that it can swing around. Furthermore, when the male screw portion 56 is further screwed into the screw hole 54 by rotating the knob portion 64, the large diameter portion 62 elastically deforms the arm member 48, thereby reducing the interval between the grooves 50. The swinging member 34 is sandwiched between the arm members 48 and the swinging of the swinging member 34 is restricted.

The groove 50, the insertion hole 52, the screw hole 54, and the set screw 58 constitute a second regulating mechanism 66. Further, the arm member 48 is fixed to the mounting member 14 with two screws 68 such that the axial direction of the rotating member 24 is orthogonal to the rotating shaft 10.

Next, the operation of the winding machine guide device of this embodiment will be explained. First, the two conductive wires 16 are each pulled out via the two sets of pull-out mechanisms 108 and passed through the insertion holes 32 of the ceramic guide 30 . This insertion hole 32
Further, the conductive wires 16 are passed through the guide holes 18 of the two nozzles 20 through the large diameter holes 28 and the large diameter holes 28, respectively.

Further, the bobbin 1 is attached to the rotating shaft 10, and the distance between the flanges 4 and 6 of the bobbin 1 is adjusted and set so as to substantially match the stroke amount of the reciprocating shaft 12. On the other hand, in this embodiment, in order to wind the two conductive wires 16 in alignment, the amount of movement of the reciprocating shaft 12 per revolution relative to the rotating shaft 10 is set to twice the diameter of the conductive wires 16. Then, by adjusting the mounting angle of the mounting member 14, the direction of the nozzle 20 is roughly adjusted so as to face the tangential direction of the conducting wire 16 wound around the bobbin 1.

Next, the screw 40 is loosened, the rotating member 24 is rotated, and the pitch P of the conducting wire 16 is adjusted as shown in FIG. 5 using the scale 44 and the mark line 25 as a guide. That is, as shown in FIG. 5(A), when both nozzles 20 are lined up along the axial direction of the rotating shaft 10, the pitch P when the two conductive wires 16 are wound around the bobbin 1 is maximum. . Furthermore, when the rotating member 24 is rotated by 90 degrees and the two nozzles 20 are arranged perpendicularly to the rotating shaft 10, the pitch P between the two conductive wires 16 becomes minimum.

For example, when the two conductive wires 16 are to be wound closely and aligned, the rotating member 24 is rotated and adjusted so that both nozzles 20 are separated by a diameter of the conductive wires 16. Next, the screw 40 is tightened to restrict the rotation of the rotating member 24 so that it does not rotate freely.

Next, loosen the set screw 58 and remove the swing member 3.
4 is swung around a swiveling shaft portion 60. At this time, the tip of the nozzle 20 is displaced while drawing an arcuate trajectory centered on the swing shaft portion 60. The tips of both nozzles 20 are finely adjusted to positions close to the bobbin 1 to such an extent that they do not come into contact with the conductive wire 16 on the outer periphery when the bobbin 1 is completely wound.

Furthermore, since the terminal insertion portion 8 also rotates,
The stroke range of the reciprocating shaft 12 is set at a position where the nozzle 20 does not collide with the terminal insertion portion 8. The tip of the nozzle 20 is adjusted so as to be closer to the body 2 and inside the terminal insertion portion 8 .

Furthermore, since the direction of the conducting wire 16 passing through the nozzle 20 also changes due to the rocking, the passing direction of the conducting wire 16 is
Fine adjustment is also made so that the winding is approximately tangential to the bobbin 1. When the adjustment is completed, the set screw 58 is tightened to restrict the swinging of the swinging member 34 around the swinging shaft portion 60.

[0030] The conductor 1 extending from the nozzle 20
6 is fixed on the bobbin 1, a rotary shaft 10 is rotated, and a reciprocating shaft 12 is reciprocated within a predetermined stroke range in synchronization with the rotation of the rotary shaft 10. Then, as the bobbin 1 rotates and the reciprocating shaft 12 reciprocates, the nozzle 2
0 moves along the axial direction of the bobbin 1.

Due to this rotation of the bobbin 1, the two conductive wires 1
6 is wound onto the bobbin 1 and drawn out via the drawing mechanism 108. The two conductive wires 16 are each guided by the guide hole 18 of the nozzle 20, and in this embodiment, the two conductive wires 16 are arranged at the same pitch P as the diameter of the two conductive wires 16, and the guide hole 18 and the ruby The two conductive wires 16 are passed through the guide 22 and wound around the bobbin 1 side by side.

[0032] Also, with one rotation of the rotating shaft 10, the reciprocating shaft 12
moves twice the diameter of the conducting wire 16, so it is wound around the bobbin 1 at a pitch P that is twice the diameter of the conducting wire 16. And 2
The conductive wires 16 are wound in close contact with each other in an aligned state. Furthermore, as the rotating shaft 10 rotates, both nozzles 20
The bobbin 1 reciprocates between the flanges 4 and 6 of the bobbin 1.
Two conductive wires 16 are simultaneously wound around.

Moreover, since the tip of the nozzle 20 is narrow, even if there is a terminal insertion part 8, it can be set close to both the flanges 4 and 6, and the nozzle 20 can be set close to both the flanges 4 and 6 of the body 2. Wrap it neatly. Furthermore, the two conductive wires 16 are each guided by the nozzle 20 separately and wound onto the bobbin 1 without the conductive wires 16 rubbing against each other.

Furthermore, since the two conductive wires 16 pass through the guide hole 18 of the nozzle 20, their passing resistance is approximately constant and they are wound with a constant tension. In this embodiment, since the ruby guide 22 is used, it is possible to prevent the tension from changing due to wear, and by forming the nozzle 20 with a wear-resistant material, it is possible to maintain a stable and constant tension for a long time. It can be wound up.

Therefore, since the two conductive wires 16 are wound on the bobbin 1 with the same tension, the lengths of both the conductive wires 16 wound on the bobbin 1 are approximately equal, and each conductor wire 16 is formed by two conductive wires 16. The resistance values of the coils are almost equal.

After winding is completed, the conductor 16 is cut, the bobbin 1 is removed from the rotating shaft 10, a new bobbin 1 is attached to the rotating shaft 10, and the above-described operations are repeated. that time,
Since each conductive wire 16 comes out from its respective nozzle 20, the end of the conductive wire 16 at the beginning of winding and the end of the conductive wire 16 at the end of winding can be easily matched. There is no need to mix up connections when making connections. Moreover, even if the conductive wire 16 is cut, it will not easily come out because it is in the guide hole 18.

As described above, the guide device for a winding machine of this embodiment guides the two conductive wires 16 through the guide holes 18 of the nozzle 20 and winds them around the bobbin 1. Further, by rotating the rotating member 24, the pitch P at which the conducting wire 16 is wound around the bobbin 1 can be adjusted, and by swinging the swinging member 34, the position of the nozzle 20 can be finely adjusted.

Therefore, when winding onto the bobbin 1,
Since the two conductive wires 16 do not rub against each other, the plating etc. will not peel off and the insulation will not be impaired. Also,
Since it is wound with almost constant tension, the two conductors 1
6, the resistance values of the coils formed respectively are almost equal,
A bobbin 1 with aligned winding is obtained, improving the reliability of the device. Furthermore, it is easy to bring the nozzle 20 close to the flanges 4 and 6, and even when winding is finished and the conductor 16 is cut, the conductor 16 does not easily come off from the nozzle 20, and the conductor 16 This improves work efficiency by eliminating the possibility of making mistakes when connecting terminals.

The present invention is not limited to these embodiments in any way, but may be implemented in various forms without departing from the spirit of the present invention.

[0040]

Effects of the Invention As described in detail above, the guide device for a winding machine of the present invention guides two conductive wires through the nozzle, rotates the rotating member, adjusts the pitch, and rotates the swinging member. It can be swung to adjust the direction of wire passage. Therefore, the two conductors will not rub against each other and the insulation will not be damaged, and
Since winding can be performed with a substantially constant tension, the resistance values of the coil formed by the two conductive wires are substantially equal, improving reliability. Furthermore, the conductive wire does not easily come off from the nozzle, the conductive wire can be identified, and there is no possibility of making a mistake in connecting it to the terminal, resulting in improved workability.
