Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire winding method, a wire winding apparatus, and a wire winding mechanism for winding a wire around a bobbin to manufacture a coil.

[0002]

2. Description of the Related Art Conventionally, a wire is wound around a bobbin by applying a predetermined tension to the wire between a wire supply side and a bobbin around which the wire is wound, and rotating the bobbin to rotate the wire at a winding position. Is reciprocated between the flanges of the bobbin.
The bobbin for the coil is generally formed of resin, and the flanges at both ends of the bobbin are slightly warped. The warpage of the flange causes the wire wound around the bobbin to be caught on the outer peripheral end of the flange when moving to the flange end. Since the wire has tension, it vibrates like a string when it is caught on a flange. At this time, if the winding position of the wire is shifted, so-called turbulent winding occurs in which the arrangement of the wire is disturbed.

When turbulent winding occurs, the laminating surface of the bobbin becomes uneven, so that when the bobbin is molded with a resin in a molding process, the thickness becomes non-uniform and the quality deteriorates. Conventionally, in order to prevent or reduce the above-mentioned irregular winding, the winding position of the wire on the bobbin is generally controlled by a guide roller or the like.

[0004] As this kind of wire winding method and wire winding device, those disclosed in Japanese Patent Application Laid-Open Nos. 5-258894 and 6-181139 are known. In the winding method and the winding device disclosed in Japanese Patent Application Laid-Open No. 5-258894, the position and the moving direction of the wire wound on the bobbin are detected by a sensor, and the wire is moved in accordance with the movement of the winding position of the wire. The control which moves the guide roller which guides is performed.

In the winding method and the winding device disclosed in Japanese Patent Application Laid-Open No. 6-181139, a pulley that is rotatable and movable in the axial direction of the bobbin is provided along the axial direction of the bobbin, and the wire is attached to the pulley. It is wound around the bobbin while it is wound. Further, when the first layer of the wire is wound, control is performed to move the pulley along the axial direction of the bobbin. The control of moving the pulley during the winding of the first layer is performed because the winding of the first layer of the wire is difficult because there is nothing to guide the wire to the cylindrical portion of the bobbin. Although the length of the wire wound around the coil changes due to the occurrence of random winding, the resistance value slightly changes, but this change hardly affects the magnetomotive force of the coil.

[0006]

SUMMARY OF THE INVENTION Incidentally, Japanese Patent Application Laid-Open No.
In the winding method and the winding device disclosed in Japanese Patent No. 258984 and the like, when the traveling direction of the wire is reversed at the flange end at the time of winding the wire, the wire is caught on the outer peripheral end of the flange, and the wire is wound on the cylindrical portion of the bobbin. If the winding position is deviated, the winding position does not match the guide position by the guide roller (the wire feed position), which causes a problem that turbulent winding is more likely to occur. As a result, there is a problem in that the outer shape defect rate of the coil increases, the manufacturing yield decreases, and the manufacturing cost increases.

[0007] In the winding method and the winding device disclosed in Japanese Patent Application Laid-Open No. 6-181139, the wire is caught on the outer peripheral end of the flange when the traveling direction of the wire is reversed at the flange end during winding of the wire. In this case, the movement of the pulley in the axial direction cannot follow the deviation of the winding position of the bobbin, and the winding position of the bobbin does not match the sending position of the wire from the pulley, and rather, turbulent winding occurs. There was a problem. In addition, the position of the wire wound around the pulley in the axial direction is not regulated on the pulley, and since the pulley is rotatable, the pulley moves in the axial direction when winding the first layer. Even if you control,
The wire could not be correctly fed to a predetermined winding position. In other words, the control of moving the pulley is not effective in orderly aligning the winding of the first layer of the wire (so-called aligned winding).

In general, the winding of a wire around a bobbin is
It is controlled by the number of turns, such as 1000 turns and 2000 turns. The winding start position and the winding end position are on the same flange end side, and the terminal is formed at this position. For example, when a wire having an outer diameter of 1 mm is used, a coil is manufactured by winding the wire 1000 times around a bobbin having a cylindrical portion of 50 mm in length. At this time, since the wire rod reciprocates 10 times on the bobbin (the number of stacked wire rods is 20), the winding start position and the winding end position are on the same flange end side.

However, if turbulent winding occurs during winding, the arrangement of the wires is disturbed, so that the winding end of the wires may not be at the flange end of the bobbin. In such a case, the device is manually operated to operate the flange end. I had to wind the wire until it. As a result, manufacturing man-hours increase,
There is a problem that the manufacturing cost increases. Further, as described above, when the wire is hooked on the outer peripheral end of one of the flanges, the wire vibrates due to the impact using the tensioner and the bobbin as nodes. Since the vibration is hardly attenuated by the tension of the wire, in the worst case, the vibration may continue even when the winding position of the wire moves to the other flange end. In such a case, there is a problem that the vibrating wire tends to collide with the outer peripheral end of the other flange, and new turbulence is generated. As a result, there is a problem that the production yield of the coil is significantly reduced.

SUMMARY OF THE INVENTION The present invention has been made to solve such a conventional problem, and a wire winding method capable of reliably winding a wire on a bobbin in an aligned manner and reducing the manufacturing cost. It is an object of the present invention to provide a wire winding device and a wire winding mechanism.

In the wire winding method of reciprocating between the two flanges of the bobbin and spirally winding and laminating the wire around the cylindrical portion of the bobbin, a detection method is provided at a position corresponding to one flange side of the bobbin. The unit detects that the wire has moved to the flange side end, and the end of the winding of the wire is counted by the control unit by counting the number of detections by the detection unit, and when a predetermined count value is reached. The rotation of the bobbin is stopped.

According to a fourth aspect of the present invention, in the wire winding device, a predetermined tension is applied to the wire between a wire supply side and a bobbin for winding the wire, and the wire is wound while rotating the bobbin. The turning position is reciprocated between the flanges of the bobbin,
In a wire winding device for spirally winding and laminating the wire around the cylindrical portion of the bobbin, on the supply side of the wire of the bobbin, at the time of winding the first layer of the wire around the cylindrical portion, It moves along the axial direction of the bobbin while contacting the wire, guides the wire to a predetermined winding position, and at the time of winding the second and subsequent layers of the wire around the cylindrical portion, A guide member retracted at a position where it does not contact is provided.

According to a fifth aspect of the present invention, in the wire winding apparatus of the fourth aspect, the predetermined winding position in the winding of the first layer is guided by the guide member. The wire material may be located at a position overlapping an end of the wire material wound immediately before the cylindrical portion on a winding progress side. A wire winding device according to a sixth aspect of the present invention is the wire winding device according to the fifth aspect, wherein the guide member has a shaft extending in an axial direction of the bobbin, and the winding at the shaft. An abutting portion that is provided at a leading end on a traveling side and extends in a direction perpendicular to the shaft portion and the wire, and contacts the winding proceeding side of the wire and urges the wire toward the reverse winding proceeding side; Is provided.

According to a seventh aspect of the present invention, in the wire winding apparatus, a predetermined tension is applied to the wire between a supply side of the wire and a bobbin around which the wire is wound, and the wire is wound while rotating the bobbin. The turning position is reciprocated between the flanges of the bobbin,
In a wire winding device for spirally winding and laminating the wire around a cylindrical portion of the bobbin, the wire is provided at a position corresponding to one flange side of the bobbin on a supply side of the wire, and the flange side of the wire is provided. A detection unit for detecting the movement to the end, and a control unit for counting the number of detections by the detection unit and stopping the rotation of the bobbin when the number of detections reaches a predetermined number of times.

According to a eighth aspect of the present invention, there is provided a wire winding mechanism provided between a wire supply side and a bobbin for winding the wire to apply a predetermined tension to the wire, and a winding for rotating the bobbin. A wire winding mechanism for spirally winding and laminating the wire on the cylindrical portion of the bobbin while reciprocating the winding position of the wire between the two flanges of the bobbin, the tensioner and A vibration damping device for preventing vibration of the wire is provided between the winding device and the vibration damping device. The vibration damping device has a contact portion extending in the axial direction of the bobbin and contacting the wire. And a resilient member for movably supporting the damping member on the contact portion side.

According to a twelfth aspect of the present invention, in the wire winding mechanism of the eighth aspect, the contact portion comprises a roller rotatably supported at both ends by the vibration damping member. And A wire winding mechanism according to claim 10, wherein the contact portion has a sharpened portion on the wire side, and a rubber member having a side opposite to the wire fixed to the vibration damping member. It is characterized by being made of a material.

(Function) In the wire winding method of the first aspect and the wire winding apparatus of the fourth aspect, when the first layer of the wire is wound around the bobbin, the guide member moves in the axial direction of the bobbin. The wire is guided to a predetermined winding position while moving. By this guide, the wire is also regularly wound around the cylindrical portion of the bobbin having no groove for guiding the wire at a predetermined position. For this reason, a spiral groove having the same groove spacing and no disturbance is formed by the wire wound on the first layer. When winding the second and subsequent layers of the wire, the guide member is retracted to a position where it does not contact the wire,
The wire is regularly formed without being controlled from the outside, following the spiral groove formed by the wire wound on the lower layer. As a result, the wire is reliably wound around the bobbin.

A wire winding method according to claim 2 and a wire winding method according to claim 5.
In the wire winding device of (1), the guide member guides the wire to a position overlapping with the end of the wire wound immediately before the cylindrical portion of the bobbin when the first layer of the wire is wound on the winding progress side. The guided wire is wound around the cylindrical portion while pressing the wire wound immediately before to the side opposite to the winding progress side. For this reason, the wire is wound tightly. As a result, when the first layer of the wire is wound, a spiral groove is formed on the surface with the same interval between the grooves and without disturbance, and the winding of the second and subsequent layers of the wire is performed reliably and regularly.

A wire winding method according to claim 3 and claim 7.
In the wire winding device of (1), each time the wire is wound around the bobbin and moves to one flange side end, this movement is detected by the detection unit. Further, the control section counts the number of detections by the detection section, and when the count reaches a predetermined count value, the rotation of the bobbin is stopped, and the winding of the wire ends. That is, unlike the related art in which the winding of the wire is completed when the number of windings reaches a predetermined number, the winding of the wire is completed when the wire is always wound up to the flange end of the bobbin.

In the wire winding device of the sixth aspect, at the time of winding the first layer of the wire, the winding progress side of the wire is formed in a rod shape extending in a direction perpendicular to the axial direction of the bobbin and in a direction perpendicular to the wire. The wire comes into contact with the contact portion, and the wire is urged by the contact portion to the opposite side of the winding. And, by this bias, the wire wound on the bobbin becomes a slightly acute angle with respect to the axis of the bobbin, and is located at a position overlapping with the end of the wire wound immediately before the cylindrical portion of the bobbin on the side where the winding progresses. The wire is guided.

When the winding position of the wire is moved to the end of the flange, and the winding of the first layer is completed, the guide member is further moved to the side where the winding of the first layer is advanced, so that the abutment is achieved. The contact and the pressing of the wire by the portion are easily released. With this release, when the winding of the wire moves from the first layer to the second layer (when the direction of winding is reversed), the guide member is retracted to a position where it does not contact the wire. Therefore, even when the wire rod collides with the outer peripheral end of the flange at the time of reversing the traveling direction of the winding, the winding position of the wire rod is not shifted due to the external force of the guide member or the like, and random winding does not occur. As a result,
The guide member having a simple shape guides the wire only at the time of winding the first layer, so that the wire is reliably wound around the bobbin.

In the wire winding mechanism according to the eighth aspect, even when the wire collides with the outer peripheral end of the flange during winding, the contact portion of the vibration damping member elastically contacting the wire is used. Is prevented from vibrating. For this reason, the winding position around the bobbin does not shift, and the occurrence of random winding is prevented. Further, since the damping member is movably supported on the contact portion side by the elastic member, even when the outer diameter of the laminated portion is increased by winding the wire around the bobbin, the wire may be separated from the contact portion. The wire rod is prevented from vibrating.

In the wire winding mechanism of the ninth aspect, the wire wound on the bobbin comes into contact with the roller rotatably supported by the vibration damping member, so that the contact resistance between the wire and the vibration damping member is minimized. As a result, vibration of the wire is prevented. For this reason, the contact between the wire and the damping member is prevented from affecting the winding of the wire. In the wire winding mechanism of the tenth aspect, since the wire wound on the bobbin is contacted by a rubber material having a sharpened wire side, vibration of the wire is minimized by minimizing contact resistance between the wire and the vibration damping member. Is prevented. For this reason, the contact between the wire and the damping member is prevented from affecting the winding of the wire.

And a supply device (corresponding to the supply side) of the wire rod 16 not shown.

The winding device 10 has a box-shaped main body 18, which has a mounting shaft 22 of a bobbin 20 projecting from a side surface 18a and a guide rod 24 (corresponding to a guide member). And are attached. In the main body 18, the mounting shaft 22 is rotated a predetermined number of times, and the guide rod 24 is

The guide rod 24 is formed by bending a distal end of a round bar made of stainless steel or the like at a right angle, and includes a shaft portion 24a extending in the axial direction A of the bobbin 20 and a wire rod perpendicular to the axial direction A. 16 and an abutting portion 24b extending upward at right angles to the supply direction B. As shown in FIG. 2, the guide rod 24 is mounted on the mounting shaft 22 on the side of the vibration damping device 12, and the shaft portion 24a of the guide rod 24 and the mounting shaft 22 are substantially at the same height. I have. Tip 24c of contact portion 24b
Are the outer peripheral ends 20 of the flanges 20a and 20b of the bobbin 20.
Projecting above c. That is, the contact portion 24b
Can guide the wire 16 even if the position of the wire 16 wound around the bobbin 20 in the height direction changes.

As shown in FIG. 1, the damping device 12 has a U-shaped damping holder 26 (corresponding to a damping member) whose upper side is open, and both ends are rotatably supported by the damping holder 26. Cylindrical roller 28 made of hard material such as glass
(Corresponding to the contact portion), a support shaft 30 hanging down from the vibration suppression holder 26, a stand 32 having an insertion hole 32a into which the support shaft 30 is slidably inserted, and between the vibration suppression holder 26 and the stand 32. And a coil spring 34 (corresponding to an elastic member) which is disposed with the support shaft 30 inserted through and elastically supports the vibration damping holder 26.

As shown in FIG. 2, even if the position of the wire 16 wound around the bobbin 20 in the height direction is changed, the roller 28 The spring constant and the spring length are determined so that they can be followed and supported. In addition, as shown in FIG.
The length L1 of the roller 28 is the cylindrical portion 20d of the bobbin 20.
, And is arranged such that both ends of the roller 28 are located outside both the flanges 20 a and 20 b of the bobbin 20.

As shown in FIG. 1, a plurality of reels 14a controlled by magnetic force or friction are provided on the tensioner 14.
Are mounted on the reel 14a.
Is wound on the wire 16 to give a predetermined tension. In the above-described winding mechanism, the wire 16 is wound around the bobbin 20 as described below, and a coil is manufactured.

FIG. 4 shows a state in which the leading end of the wire 16 is wound around the flange 20a of the bobbin 20 on the winding device 10 side, and the winding is started. The guide rod 24 is in the contact portion 2
4b is the flange 20 of the cylindrical portion 20d.
It is housed in the winding device 10 until it is located at the a-side end. The wire 16 is lightly contacted with and supported by the rollers 28 of the vibration damping device 12.

When a switch (not shown) of the winding device 10 is turned on, the mounting shaft 22 starts rotating in the rotation direction R as shown in FIG. From the first direction toward the flange 20b.
It moves to the winding progress side C of the layer. At this time, the driving mechanism (not shown) of the winding device 10 connects the guide rod 24 to the mounting shaft 2.
Control for moving by the outer diameter of the wire 16 for one rotation of 2 is performed. Then, the wire 16 is wound around the cylindrical portion 20d of the bobbin 20 from the end of the flange 20a.

As shown in FIG. 6, when the wire 16 is wound, the position of the contact portion 24b of the guide rod 24 is determined by setting the winding position D of the wire 16A guided by the bobbin 20 to the cylindrical portion 2.
The position is controlled so as to overlap the end of the wire rod 16B wound immediately before 0d on the winding progress side C. Contact part 24
The wire 16A guided by b is wound around the cylindrical portion 20d while pressing the wire 16B wound immediately before against the winding progress side C, so that the wire 16A is firmly wound without any gap. . As a result, with the wire 16 wound around the cylindrical portion 20d, a spiral groove 36 is formed on the outer surface of the wire 16 with the same interval between the grooves and without disturbance.

Thereafter, as shown in FIG. 7, the wire 16 is wound up to the end of the flange 20b of the cylindrical portion 20d, and the winding of the first layer is completed. After the winding of the first layer is completed, the guide rod 24 is continuously controlled by the control mechanism, and
4b is moved until it is positioned on the winding progress side C of the flange 20c. That is, when the winding of the wire 16 moves from the first layer to the second layer (when the winding direction is reversed), the contact portion 24b is retracted to a position where it does not contact the wire 16. . Therefore, when reversing the winding direction,
Even when the wire 16 collides with the outer peripheral end of the flange 20b, the winding position D of the wire 16 is not shifted due to the external force of the guide rod 24 or the like, and turbulent winding does not occur.

As shown in FIG. 8, the winding of the second-layer wire 16 around the cylindrical portion 20d is performed reliably and regularly by following the spiral groove 36 formed by the first-layer wire 16. . The winding of the third and subsequent layers of the wire 16 is also performed by following the spiral groove 36 formed by the lower wire 16. When winding the second and subsequent layers, the contact portion 24 of the guide rod 24
b holds the evacuated state.

Further, as shown in FIG. 2, as the wire 16 is wound over a plurality of layers, the outer diameter of the laminated portion increases, and when the wire 16 moves upward, the vibration damping member 12
Roller 28 rises by the action of the coil spring 34. Therefore, the roller 28 does not separate from the wire 16. Therefore, even if the wire 16 collides with the outer peripheral ends of the flanges 20a and 20b during the winding of the wire 16 around the cylindrical portion 20d, the rollers 28 elastically contacting the wire 16 The wire 16 is prevented from vibrating. For this reason, the winding position of the wire 16 around the bobbin 20 is prevented from being shifted, and the occurrence of irregular winding is prevented.

After the mounting shaft 22 has been rotated a predetermined number of times, the control mechanism stops the rotation of the mounting shaft 22, and the winding of the wire 16 around the bobbin 20 is completed. In the wire winding method, the wire winding device, and the wire winding mechanism configured as described above, the first layer of the wire 16 is wound on the guide rod 2.
4 along the axial direction A of the bobbin 20 to move the wire 16
Is guided to a predetermined winding position D, and the winding of the second and subsequent layers of the wire 16 is retracted to a position where the guide rod 24 is not in contact with the wire 16 and formed by the wound lower wire 16. It was performed following the spiral groove 36 which was made. Therefore, the winding of the first layer of the wire 16 can be regularly performed by using the guide rod 24, and the winding of the second layer and the subsequent layers of the wire 16 can be performed by the guide rod 2.
4 can be performed regularly without using the spiral groove 36 formed in the lower layer. As a result, the wire 16 can be reliably wound around the bobbin 20.

The guide rod 2 at the time of winding the first layer is
The winding position D of the wire 16 guided by the
Since the wire 16 is positioned so as to overlap the end of the wire 16 wound immediately before 0d on the winding progress side C, the wire 16 can be wound regularly and tightly when the first layer of the wire 16 is wound. By following the spiral groove 36 formed in the first layer,
The winding of the second and subsequent layers of the wire 16 can be performed reliably and regularly.

Since the guide bar 24 having the shaft portion 24a and the contact portion 24b is formed by bending a round bar made of stainless steel or the like, the guide bar 24 can be easily formed. Furthermore, since the guide rod 24 has a simple shape with only the shaft portion 24a and the contact portion 24 extending at right angles to each other, the control mechanism controls the movement of the guide rod 24 only in the axial direction A of the bobbin 20. Only by this, the winding of the first and second layers of the wire 16 can be easily performed.

Further, since the vibration damping device 12 having the roller 28 rotatably and elastically in contact with the wire 16 is disposed between the tensioner 14 and the winding device 10,
6 can be reliably prevented from vibrating, and the occurrence of turbulent winding can be prevented. And the roller 28
The vibration damping holder 26 that supports the roller
, The contact resistance between the wire 16 and the roller 28 can be minimized, and the contact between the wire 16 and the roller 28 affects the winding of the wire 16. Can be prevented.

FIG. 9 shows a second embodiment of the wire winding method of the present invention (corresponding to claims 1 to 3) and a second embodiment of a wire winding device (claim). 4 to 7). In this embodiment, the winding device 40 has a detection unit 44 that detects the movement of the wire 16 on the supply side of the wire 16 of the main body 42. The main body 42 is the same as the main body 18 of the winding device 10 of the first embodiment except for a built-in control mechanism (not shown). The same components as those in the first embodiment are denoted by the same reference numerals.

The detecting section 44 is composed of a U-shaped sensor 46 having arms 46a vertically opposed in the axial direction A of the bobbin 20, and an amplifier 48 for amplifying a signal transmitted from the sensor 46. I have. At the tip of each arm 46a of the sensor 46, a pair of optical sensors 5 is provided.
0 (light-emitting unit and light-receiving unit) are attached. The optical sensors 50 are respectively mounted at positions corresponding to the flanges 20 a located on the main body 42 side of the bobbin 20.

The output terminal of the amplifier 48 is connected to the input terminal of the winding number counter 52 (corresponding to the control unit). Each time the wire 16 moves in the axial direction A and shields the optical sensor 50, the winding layer number counter 52 has a function of receiving the light-shielded signal and counting up. The measured count value is an electric signal. Is output to the main unit 42. The control mechanism (not shown) of the main body 42 has a function of stopping the rotation of the mounting shaft 22 when the count value reaches a predetermined value.

In the above-described winding device, the winding of the wire 16 is started from the side of the flange 20a of the bobbin 20, as in the first embodiment. The first layer of the wire 16 is wound by guiding the wire 16 with the guide rod 24.

When the winding of the second layer of the wire 16 is completed and the wire 16 moves to the flange 20a side, the optical sensor 50 is shielded from light by the wire 16 and the winding number counter 52
Is counted up. Similarly, each time the winding of the even-numbered layer is completed, the light sensor 50 is shielded from light, and the number-of-turned-layers counter 52 is counted up. Then, when the count value of the winding number counter 52 reaches a predetermined value, the main body 42 stops the rotation of the mounting shaft 22 and
Of the bobbin 20 is completed. For this reason, the wire 16
Is always wound around the wire 16 flange 20a
Done to the side.

In the wire winding method and the wire winding apparatus of this embodiment, the same effects as those of the first embodiment can be obtained. However, in this embodiment, one flange of the bobbin 20 is used. The optical sensor 50 is arranged at a position corresponding to the 20a side to detect that the wire 16 has moved to the end of the flange side 20a, and the completion of the winding of the wire 16 is determined. 52, and when a predetermined count value is reached, bobbin 2
Since the rotation of 0 is stopped, the wire 16 can always be wound up to the end of the flange 20b of the bobbin 20, and the wire 16 can be prevented from being wound halfway.

As a result, since it is not necessary to manually operate the winding device 40 to wind the wire 16 to the end of the flange 20a, the number of manufacturing steps can be reduced, and the manufacturing cost can be reduced. FIG. 10 shows a second embodiment (corresponding to claims 8 and 10) of a wire winding mechanism of the present invention, and the same components as those in the first embodiment are denoted by the same reference numerals. ing.

In this embodiment, a flexible plate rubber 58 (corresponding to a contact portion) having a sharpened tip is attached to the vibration damping holder 56 of the vibration damping device 54.
The configuration other than the vibration damping device 52 is the same as that of the above-described first embodiment. The length L3 of the plate rubber 58 is formed to be larger than the length L2 of the cylindrical portion 20d of the bobbin 20, and both ends of the plate rubber 58 are both flanges 20a, 20b of the bobbin 20.
It is arranged so that it may be located further outside. The same winding device as that of the first embodiment is used.

In this embodiment, the same effect as in the first embodiment can be obtained. In the first embodiment of the wire winding method, the wire winding device, and the wire winding mechanism described above, when the first layer of the wire 16 is wound, the wire 16 is disposed between the flanges 20a and 20b. Has been described using the guide rod 24, but the present invention is not limited to such an embodiment. For example, as shown in FIG.
