The winding device 1 of the present embodiment shown in fig. 1 and 2 winds a wire material to form a coil of a coreless motor. The winding device 1 includes a winding core 10, a flywheel portion 3 shown in fig. 5, and a tape attaching portion 5 shown in fig. 6.
The winding core portion 10 has a winding core 11 and a spacing restriction member 20.
The wire material is wound around the core 11. The core 11 has a pair of core members 12 and 13. The core members 12 and 13 are provided on the support member 14. The support member 14 is provided on a base (not shown) of the winding device 1.
The core members 12 and 13 are disposed vertically with an axis C perpendicular to the surface 14a of the support member 14 interposed therebetween. The base end portion 12a of the core member 12 positioned above is fixed to the surface 14a of the support member 14, and the core member 12 extends parallel to the axis C from the base end portion 12a toward the tip end portion 12 b.
The core member 13 positioned below is provided on the support member 14 via a core member approaching and separating mechanism 15 described later. The lower core member 13 can be approached to or separated from the upper core member 12 by the core member approaching and separating mechanism 15.
The core member approaching/separating mechanism 15 includes a core member holding portion 16 and a biasing member 17.
The core member holding portion 16 is provided so as to be movable along a guide rail 18 provided in the support member 14. The guide rail 18 extends in the up-down direction. Thereby, the core member holding portion 16 can move in the vertical direction.
The core member 13 has a base end portion 13a fixed to an intermediate block 16C provided in the core member holding portion 16, and the core member 13 extends parallel to the axis C from the base end portion 13a toward the tip end portion 12 b. The core member 13 is movable in the vertical direction together with the core member holding portion 16 so as to be relatively movable in the vertical direction intersecting the axis C with respect to the upper core member 12.
The urging member 17 is formed of a coil spring or the like. The urging member 17 extends in the vertical direction, and a lower end 17a thereof is locked to a bracket 16b provided in the core member holding portion 16. The upper end 17b of the biasing member 17 is engaged with a boss 19 provided on the support member 14. The urging member 17 urges the core member holding portion 16 holding the lower core member 13 upward. Thereby, the core members 12 and 13 are biased by the biasing member 17 in the direction to approach each other.
As shown in fig. 3, the core member 12 positioned above has a pair of inclined surfaces 12s, 12s extending in an inverted V shape from the upper end toward the lower end, and a pair of side surfaces 12t, 12t extending in parallel to each other from the lower ends of the inclined surfaces 12s, 12s toward the lower end.
The core member 13 located below has a pair of inclined surfaces 13s, 13s extending in a V-shape from the lower end toward the upper side, and a pair of side surfaces 13t, 13t extending in parallel to each other from the upper ends of the inclined surfaces 13s, 13s toward the upper side.
In the core 11, the core member 12 and the core member 13 are arranged at a vertical interval. Thus, the cross-sectional shape of the outer portion of the winding core 11 around which the wire 100 is wound is substantially hexagonal. Here, the substantially hexagonal shape means a tortoise shell shape in which two opposing short sides of the hexagon are shorter than the other sides.
The spacing regulating member 20 is sandwiched between the core members 12, 13, and defines the spacing between the core members 12, 13. The interval regulating member 20 extends in the axis C direction between the upper core member 12 and the lower core member 13. The spacing restriction member 20 is disposed so as to be sandwiched at least between the distal end portion 12b of the core member 12 and the core member 13 b. In the present embodiment, the distance regulating member 20 is provided in the entire range of the core members 12 and 13, and the tip end thereof is exposed from the core members 12 and 13.
The outer peripheral surface of the spacing member 20 has a first outer peripheral surface 20a, a second outer peripheral surface 20b, and a connecting curved surface portion 20 c.
The first outer peripheral surface 20a is provided to a part of the outer peripheral surface of the interval restricting member 20 in the circumferential direction around the axis C. In the present embodiment, the first outer peripheral surface 20a is provided in a range of 180 ° or more with θ centered on the axis C. The first outer peripheral surface 20a is formed with a first radius of curvature r1 about the axis C. Thus, the first outer peripheral surface 20a is disposed at a distance of the radius r1 from the axis C.
The second outer circumferential surface 20b is provided at a part of the outer circumferential surface of the interval restricting member 20 in the circumferential direction around the axis C. The second outer circumferential surface 20b is provided only at one circumferential position on the outer circumferential surface of the spacing restriction member 20. In the present embodiment, the second outer peripheral surface 20b is provided in a region facing the circumferential central portion of the first outer peripheral surface 20a with the axis C therebetween. The second outer peripheral surface 20b is provided radially inward of the first outer peripheral surface 20a about the axis C. The second outer peripheral surface 20b is formed of a curved surface having a second radius of curvature r 2. Here, the second radius of curvature r2 constituting the second outer peripheral surface 20b is smaller than the first radius of curvature r1 constituting the first outer peripheral surface 20a, for example, centered on the axis C. That is, the second outer peripheral surface 20b is disposed at a radius r2 from the center of the axis C.
The connecting curved surface portion 20c is provided between both circumferential end portions of the first outer circumferential surface 20a and both circumferential end portions of the second outer circumferential surface 20 b. That is, the connecting curved surface portion 20c connects the first outer peripheral surface 20a and the second outer peripheral surface 20b in the circumferential direction. The connecting curved surface portion 20c is formed of a curved surface having a predetermined radius of curvature.
In the spacing regulating member 20, in a state where the first outer peripheral surface 20a is in contact with both the upper core member 12 and the lower core member 13, the diameter of the portion in contact with the core members 12 and 13 is the first diameter D1(D1 is 2 × r 1).
However, the core member 12 located above the spacing regulating member 20 is provided with an inner curved surface portion 12f recessed upward at a lower end portion facing the spacing regulating member 20. The outer peripheral surface of the spacing regulating member 20 is in sliding contact with the inner peripheral curved surface portion 12 f. The inner circumferential curved surface portion 12f is provided in a curved surface shape having the same first radius of curvature r1 as the first outer circumferential surface 20a of the space restriction member 20.
The core member 13 located below the spacing regulating member 20 is provided with an inner circumferential curved surface portion 13f recessed downward at an upper end portion facing the spacing regulating member 20. The inner circumferential curved surface portion 13f is in sliding contact with the outer circumferential surface of the spacing restriction member 20. The inner circumferential curved surface portion 13f is formed in a curved surface shape having the same first radius of curvature r1 as the first outer circumferential surface 20a of the space restriction member 20.
As shown in fig. 4, in the distance regulating member 20, for example, in a state where the first outer peripheral surface 20a is in contact with the upper core member 12 and the second outer peripheral surface 20b is in contact with the lower core member 12, since the second outer peripheral surface 20b is located radially inward of the first outer peripheral surface 20a, the diameter of the portion in contact with the core members 12 and 13 is the second diameter D2 smaller than the first diameter D1 (D2 is r1+ r 2).
That is, the interval regulation member 20 has, at mutually different positions in the circumferential direction around the axis, a large diameter portion 23 in which the diameter dimension of the portion in contact with the core members 12, 13 is the first diameter dimension D1, and a small diameter portion 24 in which the diameter dimension of the portion in contact with the core members 12, 13 is the second diameter dimension D2 smaller than the first diameter dimension D1.
As shown in fig. 1 and 2, the interval regulation member 20 is driven by the drive member 21 to rotate about the axis C. The driving member 21 is composed of a motor or the like, and is provided on the back surface 14b of the support member 14. The spacing member 20 penetrates the support member 14 and is coupled to a drive shaft (not shown) of the drive member 21.
When the distance regulating member 20 is driven by the driving member 21 to rotate the distance regulating member 20 about the axis C, as shown in fig. 3, the distance between the core members 12 and 13 is maximized when the large diameter portion 23 of the distance regulating member 20 is sandwiched between the upper and lower core members 12 and 13. As shown in fig. 4, when the small diameter portion 24 of the interval regulating member 20 is sandwiched between the upper and lower core members 12 and 13, the interval between the core members 12 and 13 is smaller than when the large diameter portion 23 is sandwiched. That is, the upper and lower core members 12 and 13 move closer to and away from each other in the vertical direction by driving the spacing regulating member 20 by the driving member 21 and rotating the spacing regulating member 20 about the axis C.
As shown in fig. 5, the flyer 3 winds the wire material 100 around the winding core 11. The flywheel portion 3 is disposed to face the winding core 11 in the axis C direction.
The flywheel unit 3 includes a flywheel 31, a flywheel drive unit 32, and a flywheel moving device 33.
The flyer 31 is disposed to face the winding core 11 of the winding core portion 10 at an interval in the axis C direction. The flywheel 31 includes an arm portion 35 extending in the direction of the axis C, a nozzle 36 provided in the arm portion 35, and a pulley 37 connected to the arm portion 35.
The nozzle 36 is provided at the tip of the arm 35, and draws out the wire 100 supplied from a wire supply unit not shown. The wire 100 is guided to the nozzle 36 through a hole (not shown) provided in the arm 35. The wire 100 of the present embodiment is composed of a wire in which an insulating layer and a heat-fusion layer are coated on the outer periphery of a linear conductor.
The flywheel drive unit 32 includes a motor 34, which is a servomotor, for example. A belt 38 is wound around the motor 34 and a pulley 37 connected to the arm 35. The flywheel drive unit 32 drives the motor 34 to rotate the pulley 37 via the belt 38, thereby rotating the arm 35 of the flywheel 31.
The flywheel moving device 33 supports the flywheel 31 and the flywheel drive portion 32 and moves them in the direction of the axis C.
The flywheel unit 3 moves the flywheel 31 in the direction of the axis C by the flywheel moving device 33 while rotating the arm unit 35 by the flywheel driving unit 32, and winds the wire material 100 around the winding core 11 by the flywheel 31. Thereby, the wire 100 is wound around the core members 12 and 13 constituting the winding core 11 to form a coil.
As shown in fig. 6, the tape attaching portion 5 is provided in the winding device 1. The tape attaching portion 5 attaches the tape 101 to the wire 100 wound around the winding core 11.
The tape joining section 5 includes a pair of clamping members 51A and 51B disposed on both sides with the winding core 11 interposed therebetween. The pair of clamping members 51A, 51B are provided to face the side surfaces 12t, 13t of the core members 12, 13 constituting the core 11.
The tape 101 drawn from a reel portion (not shown) is supplied to the holding members 51A and 51B, respectively. The tape 101 is cut by a cutter (not shown) to a predetermined length. The cut tape 101 is held by the holding members 51A and 51B by suction.
The pair of gripping members 51A, 51B are driven by the driving devices 52A, 52B so as to approach or separate from each other. When the clamping members 51A, 51B are brought close to each other by the driving devices 52A, 52B, the tape 101 held by the clamping members 51A, 51B in an attracting manner is stuck to the wire 100 wound around the core 11
When the clamping members 51A and 51B are moved away from each other by the driving devices 52A and 52B, the clamping members 51A and 51B are moved away from the core 11, and the tape 101 is left in a state of being stuck to the wire 100 wound around the core 11.
The tape application section 5 includes a moving mechanism (not shown) for moving the clamping members 51A and 51B in the direction of the axis C. Thus, after the tape 101 is attached, when the clamping members 51A and 51B are moved away from the core 11 in the direction of the axis C by a moving mechanism (not shown) in a state where the wire material 100 wound around the core 11 is clamped by the clamping members 51A and 51B, the wire material 100 is removed from the core 11. That is, the tape joining section 5 functions as a device for detaching the wire 100 from the core 11.
The clamping members 51A and 51B of the tape joining section 5 are formed so as to clamp and crush the wire material 100 wound around the core 11.
In the winding device 1 as described above, the wire 100 is wound around the winding core 11 by the flyer 31 of the flyer portion 3. At this time, as shown in fig. 3, the large diameter portion 23 is sandwiched between the upper and lower core members 12 and 13 in the interval regulating member 20. In this state, the flywheel 31 is moved in the direction of the axis C by the flywheel moving device 33 while the arm portion 35 is rotated by the flywheel drive portion 32. Thus, the wire 100 is wound around the core members 12 and 13 constituting the core 11 to form a coil. At this time, since the large diameter portion 23 of the interval regulating member 20 is sandwiched between the upper and lower core members 12 and 13, the core members 12 and 13 can be prevented from being bent when the wire material 100 is wound.
After the winding of the wire 100 is completed, the tape 101 is attached to the wire 100 wound around the core 11. For this purpose, the tape 101 drawn from a reel unit (not shown) is supplied to the holding members 51A and 51B of the tape application unit 5. The supplied tape 101 is cut by a cutter (not shown) to a predetermined length, and held by the holding members 51A and 51B in an attracting manner.
Then, the pair of gripping members 51A, 51B are driven by the driving devices 52A, 52B so that they approach each other. Thereby, the tape 101 held by the clamping members 51A and 51B in an attracting manner is bonded to the wire material 100 wound around the core 11.
The clamping members 51A and 51B of the tape joining section 5 are formed so as to clamp and crush the wire material 100 wound around the core 11.
Next, as shown in fig. 4, the driving member 21 rotates the interval regulating member 20 about the axis C so that the small diameter portion 24 of the interval regulating member 20 is sandwiched between the upper and lower core members 12 and 13. Since the lower core member 13 is biased upward by the biasing member 17, the lower core member moves upward with the rotation of the interval regulating member 20, and the interval with the upper core member 12 becomes narrower.
Then, in a state where the wire rod 100 wound around the core 11 is sandwiched by the clamping members 51A and 51B, the clamping members 51A and 51B are moved away from the core 11 in the direction of the axis C by a moving mechanism (not shown). Thereby, the wire 100 is detached from the core 11. At this time, since the small diameter portion 24 of the interval regulating member 20 is sandwiched between the core members 12, 13, the interval between the core members 12, 13 becomes smaller than that when the large diameter portion 23 is sandwiched. Therefore, the wire rod 100 can be easily detached from the core 11.
After the wire 100 is removed from the core 11, the driving devices 52A and 52B move the gripping members 51A and 51B away from each other. Then, the clamping members 51A and 51B are separated from the core 11, and the tape 101 is left in a state of being stuck to the wire rod 100 wound around the core 11.
Thus, a coil in which the wire 100 is wound is manufactured.
According to the present embodiment, the spacing regulating member 20 is interposed between the core members 12 and 13, whereby the core members 12 and 13 can be prevented from being bent when the wire material 100 is wound. Therefore, the core members 12 and 13 are suppressed from being deflected when the coil is wound, and the coil can be molded with high dimensional accuracy.
The distance between the core members 12 and 13 sandwiching the distance regulating member 20 changes between the time of contact with the large diameter portion 23 and the time of contact with the small diameter portion 24 of the distance regulating member 20. Thus, the distance between the core members 12 and 13 can be changed by rotating the distance regulating member 20 sandwiched between the core members 12 and 13 about the axis C. The wire 100 is wound around the core members 12, 13 with the large diameter portion 23 of the spacing regulating member 20 interposed therebetween, and then the spacing regulating member 20 is rotated to sandwich the small diameter portion 24 between the core members 12, 13, whereby the spacing between the core members 12, 13 is narrowed. This makes it possible to easily draw out the coil wound around the core members 12 and 13.
According to the winding device 1 of the present embodiment, the outer peripheral surface of the space restriction member 20 includes the first outer peripheral surface 20a and the second outer peripheral surface 20b provided at the radially inner side of the first outer peripheral surface 20 a. Therefore, the distance between the core members 12 and 13 is increased in a state where the first outer peripheral surface 20a is in contact with both the core members 12 and 13, and the distance between the core members 12 and 13 is decreased when the second outer peripheral surface 20b is in contact with at least one of the core members 12 and 13. Thus, the distance between the core members 12 and 13 can be changed by rotating the distance regulating member 20 about the axis C.
According to the winding device 1 of the present embodiment, the second outer circumferential surface 20b is provided only at one circumferential position on the outer circumferential surface of the space restriction member 20. When the second outer peripheral surface 20b is provided only at one position in the circumferential direction, the interval between the core members 12 and 13 is narrowed when the first outer peripheral surface 20a contacts the core member 12 and the second outer peripheral surface 20b contacts the core member 13. Since the second outer circumferential surface 20b only needs to be provided at one circumferential position, the interval regulation member 20 can be easily manufactured.
According to the present embodiment, the second outer peripheral surface 20b is formed by a curved surface, so that the contact load with the core members 12 and 13 can be reduced, and the wear of the contact portions of the distance regulating member 20 and the core members 12 and 13 can be suppressed.
According to the present embodiment, the connecting portion between the first outer peripheral surface 20a and the second outer peripheral surface 20b is formed by the connecting curved surface portion 20c, so that the wear of the connecting portion between the first outer peripheral surface 20a and the second outer peripheral surface 20b of the interval restricting member 20 and the core members 12 and 13 can be suppressed when the interval restricting member 20 rotates.
According to the present embodiment, the inner curved surface portions 12f and 13f are provided on the core members 12 and 13 side, so that the wear of the contact portions between the distance regulating member 20 and the core members 12 and 13 can be suppressed.
According to the present embodiment, the present invention includes: a core member holding portion 16 that supports the core member 13 so as to be movable relative to the core member 12 in a direction intersecting the axis; and a biasing member 17 that biases the core member 12 and the core member 13 in a direction to approach each other. Thus, when the distance between the core members 12 and 13 changes with the rotation of the distance regulating member 20, the core members 12 and 13 are reliably brought into contact with the distance regulating member 20 provided on the radially inner side by the biasing member 17. With this configuration, the core members 12 and 13 can be moved closer to or away from each other without using an actuator or the like, for example, and cost reduction can be achieved.
While one embodiment of the present invention has been described above, the respective configurations and combinations thereof in the embodiment are examples, and additions, omissions, substitutions, and other modifications of the configurations can be made without departing from the scope of the present invention. The present invention is not limited to the embodiments.
For example, in the above-described embodiment, the core 11 includes the pair of core members 12 and 13, but may include three or more core members. In such a configuration, the same operational effects as those of the above embodiment can be obtained by providing the spacing regulating members 20 between three or more core members.
The second outer peripheral surface 20b of the interval regulation member 20, and the connection portion between the first outer peripheral surface 20a and the second outer peripheral surface 20b are formed by curved surfaces, but may be formed by flat surfaces.
