Description

Winding device and winding method

The present invention relates to a winding device and a winding method for winding a wire after storing the wire once.

As a coil corresponding to the downsizing of the motor, the wire is wound tightly so that no unnecessary gap is formed between the winding layers, and the winding start end and the winding end end of the wire are formed on the same winding layer. 2. Description of the Related Art A so-called alpha-winding (or also referred to as "outside-outside winding") coil which is wired is known.

As this alpha-wound coil, a double-row spiral coil having first and second coils in which a wire is spirally wound and an inner crossover wire connecting inner peripheral ends of the first and second coils is known. Have been. As such a winding device for a double-row spiral coil, there has been proposed a device provided with a storage device for linearly drawing a wire and storing the wire (see JPH11-297559A).

巻 線 In this winding device, as a pre-stage of winding, the wire rod fed from the tip of the flyer is drawn straight into a storage wire. Thereafter, the first winding is performed in which the flyer is revolved around the core and the wire fed from the tip of the flyer is wound around the core. Thereafter, a second winding is performed in which the core is rotated around the axis and the wire supplied from the wire storage means is wound around the core.

In this winding device, by deriving the wire from the outer circumference of each winding portion, the winding start end and the winding end of the wire can be relatively easily formed in the double-row spiral coil drawn from the same outermost winding layer. Can be manufactured.

In the winding device of JPH11-297559A, since the wire drawn out from the tip of the flyer is linearly drawn into a storage wire, the position of the wire wound on the winding core in the winding is not restricted. If the wire is wound around the core in a state where the position of the core is not regulated, the winding of the wire may be disturbed.

In a state where it is difficult to regulate the position of the winding core, it is conceivable to reduce the length of the wire in the storage wire in order to prevent winding of the wire. However, if the length of the wire in the storage wire is shortened, the obtained coil becomes small, and it becomes difficult to manufacture a relatively large coil.

Therefore, there is a problem that the coils that can be manufactured by the winding device in JPH11-297559A are limited to relatively small ones.

An object of the present invention is to provide a winding device and a winding method capable of winding a wire without causing turbulence even in a coil that winds a relatively large number of wires.

According to an aspect of the present invention, wire storage means for drawing wire drawn out from the tip of the flyer and storing the wire as a storage wire, and winding means for winding the wire supplied from the wire storage means around a core. A nozzle that is configured to be dividable along the axial direction and is capable of holding the wire that has been drawn out in a combined state, and a split piece movement that splits or combines the split pieces in the nozzle. And a mechanism.

According to another aspect of the present invention, there is provided a winding step including a wire storing step of drawing in a wire rod fed from a tip of a flyer and storing the wire rod as a storage wire, and a winding step of winding the stored wire rod around a core. In the wire method, a wire holding step of holding the drawn wire by a nozzle is performed after the wire storing step, and the winding step is performed after the wire holding step.

<First embodiment>
A winding device 9 according to a first embodiment of the present invention will be described with reference to FIGS.

巻 線 As shown in FIG. 1, the winding device 9 includes a pair of spindle supports 2 and 3 on the base 1. One spindle support 2 has a fixed base 2a fixed to the base 1, and a movable base 2b provided on the fixed base 2a. The movable table 2b can be moved back and forth (left and right in FIG. 1) on the fixed table 2a by the movable table drive motor 4 and the ball screw 5. That is, the moving table 2b can move in a direction approaching the spindle support 3 and in a direction moving away from the spindle support 3.

The hollow spindle 10 is supported by the movable base 2b via a bearing so as to be rotatable around an axis. A sleeve 11 is fixed to a proximal end side of the hollow portion 10a of the spindle 10. The base end of the winding jig 12 is slidably accommodated in the sleeve 11 in the axial direction.

先端 The tip 12a of the winding jig 12 is formed in a substantially circular cross-sectional shape. The tip 12a of the winding jig 12 projects from the tip of the spindle 10 facing the spindle support 3 side. The distal end portion 12a of the winding jig 12 forms a part of a winding core around which a wire 6 described later is wound. A fitting concave portion 12c is formed on a distal end surface 12b of the distal end portion 12a of the winding jig 12. The fitting recess 12c is fitted (fitted to a different diameter) so as to rotate integrally with a fitting convex member 24 fixed to a winding jig 23 on the flyer spindle 20 described later. Thereby, the winding jig 12 and the winding jig 23 rotate integrally.

フ ラ ン ジ A flange portion 12e is formed on a part of the outer periphery of the winding jig 12. A spring 13 is interposed between the flange 12e and the tip of the sleeve 11. A step portion 10b is formed on the inner periphery of the hollow portion 10a of the spindle 10. The winding jig 12 is urged by the spring 13 toward the distal end of the spindle 10 until the flange portion 12e contacts the step portion 10b of the hollow portion 10a.

The sleeve 11 protrudes from the base end of the spindle 10, and a gear 14 is fixed to this protruding portion. A gear 16 is fixed to a drive shaft 15a of the spindle drive motor 15. A belt 17 is wound around these gears 14 and 16. Therefore, when the spindle drive motor 15 is driven, the spindle 10 rotates together with the winding jig 12.

筒 A cylindrical flyer spindle 20 is rotatably supported on the other spindle support 3 via a bearing. An L-shaped flyer 30 is fixed to the flyer spindle 20. A spline portion 21a formed on the outer periphery of the rotating shaft 21 is spline-coupled to the inner periphery of the flyer spindle 20 coaxially. A winding jig support member 22 is rotatably and coaxially supported at the tip of the rotating shaft 21 via a bearing. A winding jig 23, which constitutes a part of a winding core around which a wire 6 described later is wound, is coaxially fixed to the tip of the winding jig support member 22.

The winding jig 23 is formed in a substantially circular cross-sectional shape having substantially the same diameter as the distal end portion 12 a of the above-described winding jig 12. A fitting convex member 24 protruding from the front end surface is fixed to the winding jig 23. The winding jig 23, the flyer spindle 20, the rotating shaft 21, and the winding jig support member 22 are arranged coaxially with the spindle 10 described above. The winding jig 23 is disposed so as to face the above-described winding jig 12 in the axial direction.

As a result, when the movable table 2b moves toward the spindle support table 3, the winding jig 23 and the tip end surface 12b of the winding jig 12 come into contact, and the fitting convex member 24 and the fitting concave section 12c rotate integrally. Fitting. At this time, the winding jig 12 is pressed against the winding jig 23 by the spring 13. Thereby, the winding jig 23 and the winding jig 12 are integrally connected.

The rotating shaft 21 coaxially spline-coupled to the flyer spindle 20 can be moved in the axial direction with respect to the spindle support 3 by a sleeve drive motor 25 and a ball screw 26.

The base end of the spline portion 21a of the rotating shaft 21 projects rearward (to the right in FIG. 1) of the spindle support base 3, and the gear 31 is spline-coupled to the projected portion. A gear 33 is fixed to the drive shaft 32a of the drive motor 32. A belt 34 is wound around these gears 31 and 33. Thus, when the rotating shaft 21 and the flyer spindle 20 are driven to rotate by the drive motor 32, the tip of the flyer 30 rotates around the winding jig 23.

線 A wire source 35 is disposed behind the spindle support 3. The wire 6 fed from the wire source 35 is given a predetermined tension by a tension device 36, and then guided from the base end side to the hollow portion 21b of the rotating shaft 21, and a pulley 37 provided in the hollow portion 21b. It is guided around. Thereafter, the wire 6 escapes through the hole formed in the outer peripheral surface of the rotating shaft 21 to the outside of the rotating shaft 21, penetrates the gear 31, and reaches a through hole 20 a that passes through the flyer spindle 20 in the axial direction. The wire 6 that has escaped from the through hole 20a is guided to the pulley 38 at the tip of the flyer 30.

下 A lower chuck device 39 is provided beside the flyer 30. The lower chuck device 39 has a main body 39b and a pair of holding pieces 39a provided to protrude upward from the main body 39b. The pair of holding pieces 39a are opened and closed by fluid pressure. The lower chuck device 39 grips the wire 6 by holding the tip of the wire 6 by a pair of holding pieces 39a.

The winding device 9 includes a wire storage unit 40 provided above the spindle support 3. The wire storage means 40 includes a cylinder support 41, a wire pull-out cylinder 42, an upper chuck device 44, and a front-rear drive cylinder 45.

The cylinder support 41 is provided movably in the front-rear direction (the left-right direction in FIG. 1) with respect to the spindle support 3. The rod 45 a of the front-rear drive cylinder 45 is attached to the cylinder support 41. Therefore, by driving the front-rear drive cylinder 45, the cylinder support table 41 can be moved.

線 A wire rod drawing cylinder 42, which is an air cylinder, is attached to the cylinder support 41. The wire rod drawing cylinder 42 has a rod 42a extending downward. An upper chuck device 44 is fixed to the tip (lower end) of the rod 42a. The upper chuck device 44 is moved by the wire withdrawing cylinder 42 so as to be able to approach and separate from the winding core (the winding jig 23). The upper chuck device 44 has a main body 44b and a pair of holding pieces 44a provided to protrude downward from the main body 44b. The pair of holding pieces 44a are opened and closed by the fluid pressure. The upper chuck device 44 grips the wire 6 by holding the wire 6 between a pair of holding pieces 44a. The wire accumulating means 40 causes the upper chuck device 44 to grip the wire 6 fed from the tip of the flyer 30 and pulls the upper chuck device 44 upward in the drawing by contraction of the wire pull-out cylinder 42 to separate it from the flyer 30. Thus, the wire 6 is configured to be drawn upward and stored.

The winding device 9 according to the present embodiment includes a nozzle 47 configured to be dividable along the axial direction and capable of holding an end of the wire 6 pulled out in a united state, and divided pieces 47 b on the left and right sides of the nozzle 47. 47c (FIGS. 2 and 3) and a separated piece moving mechanism (fluid pressure cylinder 48) for separating and combining the divided pieces. The nozzle 47 in this embodiment is attached to the cylinder support 41 via a split piece moving mechanism (fluid pressure cylinder 48).

(3) As shown in FIG. 3, the nozzle 47 has a base 47d formed of a hexahedron and a cylindrical portion 47e protruding from the base 47d. In the nozzle 47, a through hole 47a extending in the central axis direction of the cylindrical portion 47e is formed so as to pass through the cylindrical portion 47e and the base portion 47d. As shown in FIG. 2, the nozzle 47 has a cylindrical part 47e and a base part 47d divided along the axial direction of the through hole 47a. The nozzle 47 is attached to the cylinder support 41 via a split piece moving mechanism (fluid pressure cylinder 48) that splits or combines the left and right split pieces 47b and 47c.

The split piece moving mechanism in this embodiment is a fluid pressure cylinder 48 having a main body 48a and a pair of movable pieces 48b and 48c attached to the main body 48a and moved by fluid pressure. The pair of movable pieces 48b and 48c are provided above the winding jig 23. As shown in FIG. 3, the main body 48a of the fluid pressure cylinder 48 has a cylinder support 41 so that the wire 6 passing through the winding jig 23 and extending in the vertical direction can be sandwiched from both sides by a pair of movable pieces 48b. Attached to. The left and right divided pieces 47b and 47c of the nozzle 47 are attached to a pair of movable pieces 48b and 48c that move and separate by moving with the fluid pressure of the fluid pressure cylinder 48.

In other words, the left and right divided pieces 47b and 47c are attached so as to be independently movable left and right by a pair of movable pieces 48b and 48c. As shown in FIG. 2, the nozzle 47 is configured such that the wire 6 and the upper chuck device 44 that grips the wire 6 can be inserted between the left and right divided pieces 47 b and 47 c in a separated state. When the opposing surfaces of the left and right split pieces 47b and 47c are brought into contact with each other in a state where the wire 6 is inserted between the left and right split pieces 47b and 47c, as shown in FIG. The wire 6 is accommodated in the through hole 47a. Thus, the nozzle 47 holds the wire 6 movably in the longitudinal direction.

When the wire 6 gripped by the upper chuck device 44 is pulled out together with the contraction of the wire pull-out cylinder 42, the nozzle 47 according to the present embodiment is pulled in by the upper chuck device 44 being separated from the flyer 30 and is drawn in the vertical direction. Is configured to be able to hold the end of the wire 6 extending toward the flyer 40 side.

Next, a winding method using the winding device 9 will be described.

As described above, the winding device 9 includes a wire storage unit 40 that draws in the wire 6 fed from the tip of the flyer 30 to store the wire, a nozzle 47 that can hold an end of the wire 6 that has been drawn out, Is provided. The winding method using the winding device 9 includes a wire storing process in which the wire 6 drawn out from the tip of the flyer 30 is drawn in and stored as a wire, and an end of the wire 6 drawn out after the wire storing process. There is a wire holding step of holding by the nozzle 47 and a winding step of winding the stored wire 6 around the winding core (the tip 12a of the winding jig 12) after the wire holding step.

In addition, the coil to be obtained is a so-called alpha-winding (or also referred to as “outer-outer winding”) coil in which the inner peripheral end is connected and the winding start end and the winding end end of the wire 6 become the outermost layer. In some cases, between the wire storing step and the winding step, a portion of the wire 6 unreeled from the tip of the flyer 30 before the stored portion is wound around the winding core (the winding jig 23). Is performed. These steps are described in detail below.

<Wire storage process>
First, the work of arranging the wire 6 on the winding device 9 is performed. In the wiring work of the wire 6, as shown in FIG. 1, the wire 6 fed from the wire source 35 is guided to the pulley 38 at the tip of the flyer 30 via the tension device 36, the pulley 37, and the through hole 20 a. Further, the tip of the wire 6 is held by the lower chuck device 39 at the tip of the pulley 38.

Next, the wire rod withdrawing cylinder 42 of the wire storage means 40 is operated, and the upper chuck device 44 at the tip of the rod 42 a is lowered to the vicinity of the lower chuck device 39. The winding jig 23 is retracted together with the rotating shaft 21 by the sleeve drive motor 25 so as not to hinder the lowering of the upper chuck device 44.

As shown in FIG. 2, the fluid pressure cylinder 48, which is a split piece moving mechanism, separates a pair of movable pieces 48b, 48c and separates the left and right split pieces 47b, 47c of the nozzle 47 attached thereto. The upper chuck device 44 is allowed to descend and ascend in the meantime.

After lowering the upper chuck device 44 to the vicinity of the lower chuck device 39, the end of the wire 6 gripped by the lower chuck device 39 is gripped by the upper chuck device 44 by being pinched by the pair of holding pieces 44a. Let it. After that, the gripping of the wire 6 by the lower chuck device 39 is canceled. Subsequently, the rod 42a of the wire pull-out cylinder 42 is contracted, and the upper chuck device 44 holding the end of the wire 6 is raised as shown by a solid arrow in FIG. Thus, the wire 6 can be pulled out from the tip of the flyer 30 upward, and the drawn wire 6 can be relatively easily stored as a storage wire. As described above, since the wire storing step is performed by moving the upper chuck device 44 holding the wire 6 fed from the tip of the flyer 30 away from the flyer 30 and drawing the wire 6 held by the upper chuck device 44, The storage can be performed relatively easily.

<Wire rod holding process>
In this step, the end of the wire 6 drawn out in the wire storing step is held by the nozzle 47. In the wire storing step, the nozzle 47 is in a divided state as shown in FIG. The nozzle 47 raises the upper chuck device 44 gripping the end of the wire 6 and pulls the wire 6 at the end near the flyer 30 (ie, between the upper chuck device 44 and the flyer 30 after being lifted). The wire 6 is provided at a position where the wire 6 can hold the flyer 30 side end). The fluid pressure cylinder 48, which is a split piece moving mechanism, brings the pair of movable pieces 48b and 48c closer to each other and combines the left and right split pieces 47b and 47c attached thereto as shown in FIG. Thus, the wire rod 6 existing between the left and right divided pieces 47b and 47c is held by the combined nozzle 47 so as to be movable in the longitudinal direction. As described above, the wire holding step is performed by uniting the divided nozzles 47 at the end of the drawn wire 6 on the flyer 30 side.

<First winding step>
The first winding step is a winding step different from a second winding step described later. In the first winding step, a portion of the wire 6 unreeled from the tip of the flyer 30 before the stored portion is wound around the winding core (winding jig 23).

Specifically, the winding jigs 12 and 23 are moved in directions approaching each other by the movement of the moving table 2b by the moving table drive motor 4 and the movement of the rotary shaft 21 by the sleeve drive motor 25 in FIG. At this time, the wire 6 from the wire storage means 40 is also advanced by the movement of the winding jig 23 by the advance of the wire storage means 40 by the front-rear drive cylinder 45.

As a result, as shown in FIG. 4, the end surfaces of the winding jigs 12 and 23 abut against each other, and the tip 12 a of the winding jig 12 pressed by the winding jig 23 is opposed to the spring 13. It retracts to a position where it is completely contained within the spindle 10. Thus, only the winding jig 23 is exposed as a core between the spindle 10 and the winding jig support member 22.

(4) Subsequently, by driving the drive motor 32 (FIG. 1), the tip of the flyer 30 revolves around the winding jig 23 as indicated by the solid arrows in FIGS. As a result, the wire 6 newly fed out from the tip of the flyer 30, that is, the portion of the wire 6 before the stored portion is wound around the outer periphery of the winding jig 23 until a predetermined number of turns is reached.

At this time, the drive motor 32 (FIG. 1) uses the first winding means for winding a portion of the wire 6 unreeled from the tip of the flyer 30 before the wire storing means 40 around the winding core (winding jig 23). (Winding means different from the second winding means described later). Thereby, the first-stage winding in the first winding step (a winding step different from the second winding step) is performed on the winding jig 23.

逃 As shown in FIG. 4, a relief groove 10c is formed on the distal end surface of the spindle 10. By storing the stored wire 6 in the escape groove 10 c, it is possible to prevent a portion of the wire 6 before the stored wire from becoming an obstacle when winding the outer periphery of the winding jig 23. . Since the stored wire 6 is gripped by the upper chuck device 44 above the winding jig 23, the stored wire 6 is not pulled out when the flyer 30 revolves, and is correctly wound. A line is made.

<Second winding step>
In this step, as shown in FIG. 5, the stored wire 6 is wound around a winding core (the tip 12 a of the winding jig 12). When performing the above-described first winding step (a winding step different from the second winding step), after the first-stage winding in the first winding step, the moving stage drive shown in FIG. With the movement of the movable base 2b by the motor 4, the spindle 10 is retracted from the winding jig 23 side. That is, the spindle 10 is moved away from the winding jig 23. At this time, since the winding jig 12 is urged by the spring 13, the contact between the end surfaces of the winding jigs 12 and 23 is maintained. Thereby, as shown in FIG. 5, the distal end portion 12 a of the winding jig 12 protrudes from the distal end side of the spindle 10 by the retreat of the spindle 10. The protruding portion of the tip portion 12a serves as a winding core for the second stage winding in this winding process.

As shown by the dashed arrow in FIG. 5, the second-stage winding rotates the spindle 10 by driving the spindle drive motor 15 (FIG. 1) to thereby store the wire 6 stored on the wire storage means 40 side. Is wound around the outer periphery of the tip portion 12a of the winding jig 12 until a predetermined number of turns is reached. At this time, the spindle drive motor 15 (FIG. 1) constitutes second winding means for winding the wire 6 supplied from the wire storage means 40 around the winding core (the tip 12a of the winding jig 12).

In this case, as shown by a solid arrow in FIG. 5, the flyer 30 is also rotated synchronously with the spindle 10 to keep the positional relationship between the flyer 30 and the winding jigs 12 and 23 constant.

で は In the winding of the second stage, the wire withdrawing cylinder 42 (FIG. 1) of the wire storage means 40 is set in a free state by switching the pneumatic circuit. Accordingly, the upper chuck device 44 provided at the lower end of the rod 42a is in a state where it can be freely lowered as shown by the one-dot chain line arrow in FIG. As a result, the wire 6 stored as the storage wire at the time of the first-stage winding is supplied for winding as the upper chuck device 44 descends. Then, the resistance when air is discharged from the cylinder portion of the wire rod drawing cylinder 42 with the extension of the rod 42 a gives an appropriate tension to the wire rod 6.

、 The wire 6 is wound around the tip 12 a of the winding jig 12 by such winding. The wire 6 is held by the nozzle 47 in the vicinity of the tip 12 a of the winding jig 12. Therefore, the axial position of the distal end portion 12a of the winding jig 12, which is the core of the wire 6, is regulated. Here, when the wire 6 is not regulated, the wire 6 may move in the axial direction of the distal end portion 12 a of the winding jig 12, and the winding of the wire 6 may be disturbed. On the other hand, in the present embodiment, since the position of the wire 6 in the axial direction of the distal end portion 12a of the winding jig 12 is regulated, the winding of the wire 6 is not disturbed.

In this way, when the first stage and the second stage are wound on the leading end 12a of the winding jig 23 and the winding jig 12, the gripping of the end of the wire 6 by the upper chuck device 44 is released. Then, the wire 6 is cut on the flyer 30 side by a cutter device (not shown). Further, the winding jig 12 is retracted by the movement of the moving table 2b by the moving table drive motor 4, and the connection with the winding jig 23 is released, so that the completed so-called alpha winding (or also referred to as "outside winding") is completed. )), And a series of winding operations is completed.

<Second embodiment>
A winding device 50 according to a second embodiment of the present invention will be described with reference to FIGS.

As shown in FIGS. 6 and 7, the winding device 50 according to the second embodiment includes a flyer 62 that feeds out the wire 6 from the tip, similarly to the winding device 9 according to the first embodiment. The winding device 50 includes a traverse mechanism 51 that moves the flyer 62 in the rotation axis direction. In the second embodiment, three axes X, Y, and Z that are orthogonal to each other are set, and the X axis extends in a substantially horizontal horizontal direction, the Y axis extends in a substantially horizontal front-rear direction, and the Z axis extends in a substantially vertical direction. The configuration of the wire device 50 will be described.

As shown in detail in FIG. 7, the traverse mechanism 51 includes a traverse motor 52 provided on a base 50a, a ball screw 53 connected to an output shaft of the traverse motor 52 and extending in the rotation axis direction of a flyer 62, A moving body 54a to which the screw 53 is screwed, a guide rail 55 arranged on the base 50a in parallel with the ball screw 53 to guide the moving body 54a, a moving body 54b guided by the guide rail 55, and a moving body And a movable table 56 to which 54a and 54b are attached. When the traverse motor 52 is driven, the moving bodies 54a and 54b are guided by the guide rail 55, and the moving table 56 moves in the X-axis direction.

第一 A first head 57 is erected on a movable base 56 movably provided in the X-axis direction on the base 50a. The first head 57 supports a base end side of a cylindrical first spindle shaft 59 that is rotatable via a bearing 58, and a non-rotatable second shaft on the inner periphery of the first spindle shaft 59 via a bearing 60. Supports one central body 61. An annular flange portion 59a is integrally provided at the tip of the first spindle shaft 59, and a flyer 62 is attached to the flange portion 59a.

The flyer 62 is attached at a position eccentric from the rotation axis of the first spindle shaft 59. The flyer 62 is provided with a plurality of rollers 62 a for guiding the wire 6. At the tip of the flyer 62, a tube 62b for feeding out the wire 6 is provided.

A flyer rotation motor 66 is provided on the movable base 56, and a pulley 67 is attached to an output shaft of the flyer rotation motor 66. A pulley 65 is attached near the tip of the first spindle shaft 59, and the pulley 65 and the pulley 67 are connected via a belt 68. Thus, when the flyer rotation motor 66 is driven, the first spindle shaft 59 rotates, and the flyer 62 rotates about the rotation axis of the first spindle shaft 59. Note that a through hole 59b is formed in the first spindle shaft 59 to which the flyer 62 is attached so as to be near the flyer 62 and parallel to the rotation axis. The wire 6 is inserted into the through hole 59b. That is, the wire 6 inserted into the through hole 59b is arranged so as to be parallel to the rotation axis of the flyer 62.

貫通 A through hole 61 a is formed in the first central body 61 coaxially with the rotation axis of the first spindle shaft 59. A rod 69 is inserted into the through hole 61a. The rod 69 is spline-engaged with the through hole 61 a and is movable in the rotation axis direction of the flyer 62, and is not rotatable with respect to the first central body 61. Thus, the rod 69 is configured to be relatively movable with respect to the first central body 61, and a core (bobbin 71) is attached to the tip of the rod 69.

Next, a winding method using the winding device 50 will be described.

The winding device 50 includes a wire storage unit 90 that draws in the wire 6 to store the wire, and a nozzle 47 that can hold an end of the drawn wire 6 on the flyer 62 side. The winding method using the winding device 50 includes a wire storing step in which the wire 6 drawn out from the tip of the flyer 62 is drawn in and stored as a wire, and after the wire storing step, the wire 6 pulled out is connected to the flyer 62 side.

Further, between the wire storing step and the winding step, another winding step of winding a portion of the wire 6 that is unreeled from the tip of the flyer 62 before the stored portion around the core (bobbin 71) is performed. Do. This makes it possible to obtain a so-called alpha-winding (or “outer-outer winding”) coil in which the inner peripheral ends are connected and the winding start end and the winding end end of the wire 6 become the outermost layer. These steps are described in detail below.

<Wire storage process>
First, the work of arranging the wire 6 on the winding device 50 is performed. In the wiring work of the wire 6, as shown in FIG. 7, the wire 6 supplied from the wire source (not shown) is passed through a tension device (not shown) from the rear of the frame 76 to the second spindle shaft. 81 through the through hole 81a and the through hole 59b of the first spindle shaft 59 in order. Then, it is guided to a tube 62b at the tip of the flyer 62 via a plurality of rollers 62a provided on the flyer 62. Then, the wire 6 drawn out from the tube 62b is gripped by the chuck device 92 in the wire storage means 90.

The chuck device 92 grips the wire 6 in a state of approaching the flyer 62, then drives the motor 94 of the wire storage means 90 to circulate the belt 95, and moves the chuck device 92 attached to the belt 95 to the rail 91. Along with, as shown by the solid arrows in FIG. Thus, the wire 6 gripped by the chuck device 92 is drawn from the tip of the flyer 62 and stored.

In the wire storing step, the nozzle 47 is moved by the nozzle moving mechanism 100 to a standby position where the nozzle 47 is separated from the movement locus of the chuck device 92.

<Wire rod holding process>
In this step, the end of the wire 6 drawn out in the wire storing step is held by the nozzle 47. More specifically, as shown in FIG. 10, the divided pieces 47b and 47c of the nozzle 47 are separated from each other by a dash-dot line by a fluid pressure cylinder 48 as a divided piece moving mechanism. Then, in a state where the divided pieces 47b and 47c are separated from each other, a position near the flyer 62 and at which the end on the flyer 62 side of the wire 6 extending in the X-axis direction can be sandwiched by the divided pieces 47b and 47c. The nozzle 47 is moved by the nozzle moving mechanism 100.

{Circle around (4)} The divided pieces 47b and 47c of the nozzle 47 are brought close to each other and united by a fluid pressure cylinder 48 as a divided piece moving mechanism, as indicated by a broken arrow. As a result, the drawn wire rod 6 extending in the X-axis direction is passed through the through hole 47a of the combined nozzle 47, and is held movably in the longitudinal direction. As described above, the wire holding step is performed by uniting the divided nozzles 47 at the end of the drawn wire 6 on the flyer 62 side.

<First winding step>
The first winding step is a winding step different from a second winding step described later. In the first winding step, a portion of the wire 6 unreeled from the tip of the flyer 62 before the stored portion is wound around the winding core (bobbin 71).

Specifically, the flyer rotation motor 66 in FIG. 7 is driven to rotate the first spindle shaft 59 shown in FIG. 10 as shown by a solid arrow, and the flyer 62 provided on the first spindle shaft 59 is bobbin. Orbit around 71. As a result, the wire 6 newly fed out from the tip of the flyer 62, that is, the wire 6 before the stored portion of the wire 6 is wound around the bobbin 71 until a predetermined number of turns is reached.

At this time, the flyer rotation motor 66 is configured to use first winding means (second later-described second means) for winding a portion of the wire 6 unreeled from the tip of the flyer 62 before the wire storage means 90 around the winding core (bobbin 71). Winding means different from the above winding means).

In the second embodiment, the winding core is the bobbin 71 in which three flanges 71b, 71c, 71d are formed around the winding drum 71a. In the first-stage winding in the first winding step (a winding step different from the second winding step), the winding drum portion between the pair of flanges 71c and 71d on the first spindle shaft 59 side. The wire 6 is wound around 71a, and the axial movement of the core (bobbin 71) is performed by a moving mechanism 75 (FIG. 7).

<Second winding step>
In this step, the stored wire 6 is wound around the bobbin 71. In the second-stage winding in the second winding step, the wire 6 is wound around the winding drum 71a between the pair of flanges 71b and 71c on the wire storage means 90 side. In the second embodiment, as shown in FIG. 11, the nozzle 47 holding the wire 6 movably by uniting the divided pieces 47b and 47c is moved by the nozzle moving mechanism 100 to the bobbin 71 serving as the core thereof. Is wound around the bobbin 71.

As described above, the nozzle moving mechanism 100 rotates the united nozzle 47 around the winding core (bobbin 71) to thereby rotate the wire 6 supplied from the wire storage means 90 around the winding core (bobbin 71). A second winding means for winding is constituted.

In this winding step, the bobbin 71 is projected from the first spindle shaft 59 by the moving mechanism 75 (FIG. 7), and the flyer 62 provided on the first spindle shaft 59 rotates around the bobbin 71. Interference with the nozzle 47 is prevented.

By rotating the nozzle 47 around the fixed bobbin 71 without rotating as shown by the solid arrow in FIG. 11, the chucking device holding the end of the wire 6 in the wire storage means 90 (FIG. 7) Reference numeral 92 indicates the approach to the nozzle 47 as indicated by a broken arrow, and the wire 6 passing through the nozzle 47 is sequentially wound around the bobbin 71 as a core.

At the time of feeding out the accumulating wire, a motor control means (not shown) for controlling the motor 94 of the accumulating means 90 shown in FIG. 7 rotates the motor 94 which rotates in the reverse direction due to the approach of the chuck device 92 to the nozzle 47. , An appropriate tension is applied to the wire 6 wound around the bobbin 71 through the nozzle 47.

に よ り By such a winding, the wire 6 is wound around the bobbin 71 which is a winding core. In this winding, the wire 6 is held by the nozzle 47 around the bobbin 71. For this reason, the position of the wire 6 in the axial direction of the bobbin 71 is regulated. Here, when the wire 6 is not regulated, the wire 6 may move in the axial direction of the bobbin 71, and the winding of the wire 6 may be disturbed. On the other hand, in the present embodiment, since the position of the wire 6 in the axial direction of the bobbin 71 is regulated, the winding of the wire 6 is not disturbed.

Further, in the present embodiment, since the chuck device 92 holding the wire 6 fed from the tip of the flyer 62 is moved away from the flyer 62 and the wire 6 held by the chuck device 92 is drawn in, the wire storage is performed. It is possible to relatively easily perform the storage. Further, since the nozzle 47 can be moved by the nozzle moving mechanism 100, the position of the wire 6 in the axial direction of the core (bobbin 71) can be controlled, and the variety of windings can be increased. .

Then, when the first-stage and second-stage windings are performed on the bobbin 71 serving as the core, the gripping of the end of the wire 6 by the chuck device 92 is released, and the cutter device (not shown) closes the bobbin 71 on the flyer 62 side. The wire 6 is cut. Thereafter, the lock mechanism 72 is released, and the bobbin 71, which is the core around which the wire 6 is wound, is detached from the tip of the rod 69 and discharged, thereby completing a series of winding operations.

As described above, the winding devices 9 and 50 include the wire storing means 40 and 90 for drawing in the wire 6 fed from the ends of the flyers 30 and 62 and storing the wire 6, and the wire supplied from the wire storing means 40 and 90.

A nozzle 47 capable of holding the wire 6 pulled out in a united state, and a split-piece moving mechanism (fluid pressure cylinder 48) for splitting or uniting the split pieces 47b and 47c of the nozzle 47. .

In this case, the wire storage means 40, 90 includes chucking devices 44, 92 which can move toward and away from the core (the leading end 12a of the winding jig 12, the winding jig 23, the bobbin 71). The wire rods 6 fed from the ends of the flyers 30 and 62 are gripped by 44 and 92 and separated from the flyers 30 and 62 to store the wire rods. It is preferable that the end of the wire 6 pulled in by being separated from the flyers 30, 62 on the flyer 30, 62 side is provided so as to be held.

Further, the apparatus further includes a nozzle moving mechanism 100 for moving the nozzle 47, and the nozzle moving mechanism 100 is configured so that the nozzle 47 in the united state can be circulated around the winding core (bobbin 71). Winding means for winding the wire 6 supplied from the means 90 can also be configured. Then, another winding means (drive motor 32) for winding a portion of the wire 6 unreeled from the tips of the flyers 30, 62 before the wire storage means 40, 90 around the winding core (winding jig 23, bobbin 71). , A flyer rotation motor 66).

On the other hand, the winding method includes a wire storing step of drawing in the wire 6 fed from the tips of the flyers 30 and 62 and storing the wire 6 as a wire, and a winding core (the tip 12a of the winding jig 12; And a winding step of winding around the bobbin 71), wherein after the wire storing step, a wire holding step of holding the drawn wire 6 by the nozzle 47 is performed, and after the wire holding step, , A winding process is performed.

The wire storage process is performed by moving the chuck devices 44 and 92 holding the wire 6 fed from the tips of the flyers 30 and 62 away from the flyers 30 and 62 and drawing the gripped wire 6 into the chuck devices 44 and 92. The wire rod holding step is performed by using a nozzle 47 configured to be dividable along the axial direction, and combining the divided nozzles 47 at the ends of the drawn wire rod 6 on the flyer 30 and 62 side. be able to.

The winding step is preferably performed by rotating the nozzle 47 around the winding core (bobbin 71) and winding the stored wire 6 around the winding core (bobbin 71). Also, between the wire storing step and the winding step, a portion of the wire 6 that is unreeled from the tips of the flyers 30 and 62 before the stored portion is wound around the winding core (the winding jig 23 and the bobbin 71). Preferably, another winding step for winding is performed.

According to such a winding device 9, 50 and a winding method, the nozzle 47 capable of holding the wire 6 drawn in the combined state so as to be capable of being divided and the divided pieces 47b, 47c of the nozzle 47 are divided or combined. Since the split piece moving mechanism (fluid pressure cylinder 48) is provided, the end of the drawn wire 6 on the side of the core (the leading end portion 12a of the winding jig 12, the winding jig 23, the bobbin 71) after the wire storage is provided. By holding the portion by the nozzle 47, the position of the wire wound around the core (the tip 12 a of the winding jig 12, the winding jig 23, the bobbin 71) of the stored wire 6 is regulated by the nozzle 47. can do. As a result, it is possible to prevent the winding of the wire 6 from being disturbed due to the position of the wire 6 not being restricted on the core side. That is, according to the winding devices 9 and 50 and the winding method, even a coil that winds a relatively large number of wires 6 can wind the wires 6 without causing winding disturbance.

(4) If the chuck devices 44 and 92 holding the wire 6 are stored away from the flyers 30 and 62 to store the wire, the wire can be stored relatively easily. Further, if the nozzle 47 is moved by the nozzle moving mechanism 100, the position of the wire 6 on the winding core side can be controlled, and not only a spiral coil but also a spiral coil can be created. A variety of lines can be achieved. If the nozzle 47 is made to circulate around the winding core (bobbin 71), the stored wire 6 can be wound around the winding core (bobbin 71). Furthermore, if a portion of the wire 6 before the stored portion is wound around the winding core (the winding jig 23 and the bobbin 71), it is also referred to as a so-called alpha winding (or “outside and outside winding”). ) The coil can also be easily manufactured.
