PURPOSE: To reel out the fiber reeled on a bobbin while keeping a given high tension without breaking and to impregnate the reeled-out fiber with resin at low cost and to reel the fiber on a work. CONSTITUTION: By moving a bobbin supporting section 30 along an arc of a circle centering on a guide section 26 with the fiber-reeling-out force of a fiber reeling mechanism 24 a fiber-reeling-out direction is always made perpendicular to an reel axis 16 of the bobbin 14 wherever the fiber 12 is reeled out from the bobbin 14 and thus the fiber 12 is reeled on a reeling member 22 while reducing the fiber slipping on the bobbin 14 when it is reeled out. Moreover, by use of a straight threading pipe 62 disposed in an impregnation tank the fiber 12 is impregnated with resin 60 without bend and reeled on a reeling member 22, which reduces the waste quantity of the resin 60 after impregnating operation.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fiber winding device for winding a fiber around a work, and more particularly, a fiber winding device for drawing a fine fiber wound around a bobbin and winding it around a work while maintaining a high tension. Regarding the improvement of the device.

[0002]

2. Description of the Related Art Conventionally, a wire or a fiber wound around a bobbin is drawn out from the bobbin, and the drawn wire or fiber is wound around a work, for example, a core or bobbin of a motor or a transformer, a predetermined number of times to adjust the characteristics and strength. Techniques for making adjustments are known. For example, in JP-A-61-1246, a permanent magnet is arranged on the surface of a rotor of a motor, a fiber impregnated with a thermosetting resin is wound on the permanent magnet, and the fiber is heated and cured. , A technique of fixing a permanent magnet to a rotor of a motor to improve the durability of the rotor is disclosed. In this case, since the rotor of the motor rotates at high speed,
It is required that the permanent magnets be firmly fixed with a uniform force over the entire circumference so that the permanent magnets are not scattered by the centrifugal force during rotation.

FIG. 5 shows a schematic configuration diagram of a fiber winding device for winding the fibers as described above. A glass fiber wire (hereinafter simply referred to as a glass fiber wire formed by bundling hundreds (about 800) of fibers supplied from a fiber maker in a wound state on the bobbin 100, for example, glass fibers having a diameter of about 18 μm. The fiber 102 is a substantially cylindrical bobbin 1.
It is wound in units of several hundred meters. Generally, the fiber 102 is wound around the bobbin 100 with a slight inclination from 90 ° with respect to the winding shaft 104 so as to prevent winding unevenness and to reduce the bobbin diameter uniformly when the fiber 102 is pulled out. In addition, the bobbin 100 receives a predetermined amount of rotational force (back tension) in a direction opposite to the arrow A direction in the drawing in which the fiber 102 is drawn out by a torque generator such as a motor 106 controlled to rotate at a constant speed and a powder clutch 107. Has been added. The fiber 102 has a predetermined tension by being pulled out against the back tension by the fiber winding mechanism described later. The fibers 102 pulled out from the bobbin 100 are positioned by a centering roller 108 with respect to a resin impregnation tank 110 described later. afterwards,
The fiber 102 has a plurality of rollers 112, 114, 116a,
The route is changed by 116b, etc., and the resin impregnation tank 11
It is dipped in a zero-filled resin, for example a thermosetting adhesive. On the other hand, in the fiber winding mechanism, a rotor 118 of a motor having a permanent magnet temporarily fixed on its surface is supported by a constant speed motor 120 so as to be rotatable at a constant speed. In addition, the constant speed motor 1
20 is a state in which the rotor 118 is supported, and is fed at a constant pitch in the direction of arrow B in the figure by a constant pitch feed mechanism including a control motor 122 such as a servo motor and a ball screw 124. Therefore, while rotating the rotor 118 at a low speed,
By feeding the resin-impregnated fiber 102 with a predetermined tension, the rotor 1 is fed at a constant pitch in the direction of arrow B.
18 can be wound at a constant pitch. After that, the rotor 118 around which the fiber 102 is wound is heated at a predetermined temperature for a predetermined time, whereby the resin is cured and the permanent magnet can be firmly fixed to the rotor 118 with a uniform force.

[0004]

However, since the bobbin 100 of the conventional fiber winding device only rotates around the winding shaft 104 with respect to the winding shaft 104, as shown in FIG. The rotational force of the high speed motor 120 (see FIG. 5) is the fiber 10
When 2 is pulled out against the back tension generated by the motor 106, the powder clutch 107, etc., the fiber 102 wound around the end portion 100a of the bobbin 100 moves toward the center of the bobbin 100 while sliding on the bobbin 100 ( Arrow C). As a result, the fibers 102 rub against each other and swing at the angle θ, which easily causes disconnection. When a plurality of fibers having a small diameter are bundled, even if about 1/10 of the whole is broken, the whole fiber 102 is not broken, but when wound around the rotor 118, the strength is partially reduced, There is a problem that a stable permanent magnet cannot be fixed.

When the fiber 102 swings on the bobbin 100 at an angle θ, the balance between the pulling force generated by the rotation of the constant speed motor 120 and the back tension generated by the motor 106, the powder clutch 107, etc. is lost, and the tension is reduced. Fluctuation occurs. When the fiber 102 is wound around the rotor 118, it is often performed at a value close to the limit of the tensile strength of the fiber 102, and the fluctuation of the tension causes a problem of breaking the fiber 102.

On the other hand, since a small-diameter fiber is often weak in bending strength, it is necessary to use a roller 114 having a large curvature when the fiber 102 is dipped in the resin in the resin impregnation tank 110 in order to prevent disconnection. There is. As a result, the resin impregnation tank 11
0 needs to be large enough to accommodate the roller 114, which causes a problem that a large amount of resin is discarded after the impregnation work is completed and the cost is increased.

The present invention has been made to solve the above problems, and it is possible to draw out a fiber wound around a bobbin in a stable state maintaining a predetermined high tension without breaking the fiber and wind the fiber around a work. An object of the present invention is to provide a fiber winding device that can be used.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a plan view showing the schematic construction of the fiber winding device of this embodiment, and FIG. 2 is a side view. As shown in FIG. 1, the basic configuration of the fiber winding device 10 is the same as that of the fiber winding device described in the related art, and includes a small number of fibers, for example, a glass fiber having a diameter of about 18 μm. A glass fiber wire (hereinafter simply referred to as a fiber) 12 formed by bundling 100 wires (about 800 wires) 12 is wound around a unit of several hundred meters, and a substantially cylindrical bobbin 14 is rotatable around a winding shaft 16. A bobbin supporting mechanism 18 for supporting the resin 12 on the inside, a resin impregnation tank 20 for impregnating the fibers 12 with a resin, for example, a thermosetting adhesive, and a rotor 22 for a motor, which is the work with the fibers 12 impregnated with the resin.
It is composed of a fiber winding mechanism 24 and the like. Further, a guide portion 26 for guiding the fiber 12 to the resin impregnation tank 20 or the fiber winding mechanism 24 is arranged at a position separated from the bobbin supporting mechanism 18 by a predetermined distance. The guide portion 26 is composed of a pair of rotatable rollers and guides the fiber 12 to the machine center of the resin impregnation tank 20 and the fiber winding mechanism 24.

The bobbin supporting mechanism 18 has a tension applying mechanism including a motor 28, which is controlled to rotate at a constant speed and a torque generator such as a powder clutch (not shown), as in the conventional device, and the fiber 12 is pulled out. A predetermined amount of rotational force (back tension) is applied in the direction opposite to the arrow A direction in the figure. Further, in the fiber winding mechanism 24, as in the conventional device, the rotor 22 of the motor having the surface temporarily fixed with the permanent magnet is used as the constant speed motor 1.
It is rotatably supported by 20. Further, the constant speed motor 120, while supporting the rotor 22, is fed at a constant pitch in the direction of arrow B in the figure by a constant pitch feed mechanism including a control motor 122 such as a servo motor and a ball screw 124. Therefore, the fiber 12 is the fiber winding mechanism 24.
Thus, the rotor 22 has a predetermined tension by being pulled out against the back tension, and is wound around the rotor 22 at a constant pitch.

The characteristic feature of this embodiment is that the winding shaft of the bobbin is moved by the fiber drawing force of the fiber winding mechanism according to the drawing position of the fiber on the bobbin, and the bobbin winding shaft and the fiber are always moved. This is where the direction of drawing is orthogonal.

The bobbin supporting mechanism 18 is actually the bobbin 1.
4 and a circular arc guide plate 32 having a circular arc portion 32a with a radius R centered on the guide portion 26. This arc guide plate 32 is at a predetermined position on a floating table 34, which will be described later.
That is, the radius R with the arc portion 32a centered on the guide portion 26
It has been fixed in a position that matches. Also, this arc portion 3
A tooth profile is formed on 2a. It is preferable that the tooth profile has a tooth contact with the tooth profile formed on the side of the bobbin supporting portion 30 concentrated in the center of the tooth width, and crowning is performed in order to reduce friction. On the other hand, the bobbin supporting portion 3
The contact surface side of the floating table 34 of the base plate 36 of No. 0 is smoothly finished, and a lubricant such as machine oil is preferably applied to the contact surface so that the floating table 34 can be moved with low resistance. . Further, a tooth-shaped portion capable of meshing with the tooth-shaped portion of the arc-shaped portion 32a is formed on the linear portion 36a (parallel to the winding shaft 16 of the bobbin 14) of the base plate 36 that contacts the arc-shaped portion 32a of the guide plate 32. The arc guide plate 32 and the base plate 36 are shown in FIG.
As shown in, they can move relative to each other while making point contact with each other.

Therefore, when the fiber 12 is pulled out from the center of the bobbin 14 by the fiber winding mechanism 24, the fiber pulling force of the fiber winding mechanism 24 causes the bobbin supporting portion 28 to move in the arc portion 30a as shown by the solid line in FIG. Move to the center, and the fiber 12
Take out. In addition, the fiber 1 from the end 14a of the bobbin 14
When pulling out 2, the fiber pulling force of the fiber winding mechanism 24 tilts the bobbin 14 as shown by the chain double-dashed line in FIG. The linear portion 36a of the base plate 36 and the winding shaft 16 of the bobbin 14.
Since the base plate 36 moves along the circular arc portion 30a, that is, on the circular arc locus of the radius R centered on the guide portion 26, the winding shaft 16 faces the tangential direction of the circular arc portion 30a and the bobbin 14 Even if the fiber 12 is pulled out from any position in the throat, the fiber 12 is pulled by the fiber pulling force of the fiber winding mechanism 24.
The pull-out direction and the direction of the winding shaft 16 are always orthogonal to each other. That is, the fiber 12 is pulled out substantially at right angles to the winding shaft 16, and it is possible to reduce the slippage of the fiber 12 on the bobbin 14 when the fiber 12 is pulled out. Therefore, the fibers 12 do not rub against each other due to the sideslip, so that the occurrence of disconnection can be reduced.

The base plate 36 prevents the balls 12a from rising when the fibers 12 are pulled out.
A substantially L-shaped base retainer 38 having the above is arranged. 1 and 2, the base retainer 38 is disposed only on one end side of the base plate 36, but by providing a plurality of base retainers 38 at positions that do not interfere with other members, the base plate 36 can be reliably prevented from floating. The movement can be made more stable.

The bobbin supporting mechanism 1 configured as described above
8, the resin impregnation tank 20, the guide portion 26, and the like are arranged on the floating table 34 as shown in FIG.
The floating table 34 is slightly moved by the compressed air supplied from the air supply holes 40a of the base 40 so that the base 4 is slightly moved.
While floating from 0, the four corners are supported by thin spring plate suspensions 42, and the floating table 34 supports the fibers 1
It is configured to prevent sliding in a direction orthogonal to the pull-out direction A of 2 and to allow the floating table 34 to move smoothly in the A direction and the reverse A direction when the tension changes.

Further, as shown in FIG. 3, on the side of the fiber winding mechanism 24 of the floating table 34, in order to detect the movement amount of the floating table 34 which slightly moves in the fiber drawing direction A due to the change in the tension of the fiber 12. A load cell 44 is provided as a reaction force measuring unit. Supports 46 are provided on both sides of the load cell 44.
A plate spring 48 is stretched over the plate 6. A bracket 54 that supports a metal ball 52 that contacts a side surface of a moving table 50 that is movable in the winding pitch direction B of the fiber winding mechanism 24 is fixed on the leaf spring 48. If fiber 12
When the tension of the fiber 12 fluctuates due to some reason when the fiber is pulled out, and the tension becomes large, the floating table 34 moves in the fiber withdrawing direction A, and the distance between the fiber winding mechanism 24 and the floating table 34 becomes narrow. In this case, the leaf spring 48 bends as shown by the dotted line in FIG. 3, and the load cell 44 detects the amount of bending. The deflection amount is output from the load cell 44 as a change in voltage, and is supplied to a tension control unit including a square root device using an operational amplifier, a potentiometer, and the like, and torque control of the motor 28 of the tension applying mechanism mounted on the bobbin supporting mechanism 18. I do. In this case, since the torque of the constant speed motor 120 that pulls out the fiber 12 is constant and the torque of the feeding motor 28 is controlled by the detection result of the load cell 44, the tension of the fiber 12 can always be kept at an optimum value. The movement of the moving table 50 in the winding pitch direction B is absorbed by the rolling of the metal balls 52 and does not affect the load cell 44.

Further, the floating table 34 has
As shown in FIGS. 1 and 2, the fiber 12 is added to the fiber insertion height of the resin impregnation tank 20 and the fiber supply height of the fiber winding mechanism 24 described later.
The height guide 56 and the fiber 12 for maintaining the
A guide roller 58 and the like for guiding the optimum position for winding 4 are arranged.

A resin impregnating tank 20 containing a resin 60 such as a thermosetting adhesive is arranged downstream of the guide portion 26. The resin impregnation tank 20 has a substantially cylindrical shape, and a linear insertion tube 62 is provided in the vicinity of the bottom surface in parallel with the fiber drawing direction A so as to penetrate both wall surfaces. The fiber introduction side of the insertion tube 62 has a tapered portion 6 with a widened inlet.
2a, which communicates with the inside of the resin impregnation tank 20 at the center,
Resin supply hole 62b for supplying the resin 60 into the insertion tube 62
Is provided. The resin 60 is supplied to the insertion tube 62 from the resin supply hole 62b by the capillary phenomenon, and the resin 12 is impregnated in the fiber 12 passing through the insertion tube 62. Since the diameter of the insertion tube 62 is slightly larger than the diameter of the fiber 12 (for example, φ0.8 mm), there is little leakage from both open ends of the insertion tube 62 due to surface tension.

In this way, since the resin is impregnated using the straight insertion tube 62, it is not necessary to change the fiber path by rollers or the like as in the conventional apparatus, and the size of the resin impregnation tank 20 is the resin 60. Since the size of the fiber 12 can be supplied to the insertion tube 62, the amount of resin waste after the impregnation work can be reduced, and the fiber 12 remains in a linear state.
Since it can pass through the resin impregnation tank 20, the fibers 12
It is possible to prevent disconnection due to bending without applying an extra load to the. Although the resin supply hole 62b of the insertion tube 62 shown in FIG. 4 is an example in which one relatively large hole is provided, a large number of small holes may be provided so that the resin supply hole may have a function of a filter. . Further, although a substantially cylindrical resin impregnation tank is shown in the present embodiment, if a rectangular resin impregnation tank along the insertion tube is used, the volume thereof can be further reduced, and the resin impregnation with a small amount of discarded resin can be achieved. A tank can be provided.

As described above, by moving the bobbin supporting portion on the arc centered on the guide portion by the fiber withdrawing force of the fiber winding mechanism, no matter which position of the bobbin the fiber is pulled out from, the fiber withdrawing direction is Since the winding axis of the bobbin is orthogonal to the bobbin, it is possible to reduce the sliding of the fiber on the bobbin when the fiber is pulled out, and the fibers do not rub against each other due to the sideways sliding, so that the occurrence of wire breakage can be reduced. Further, since the resin can be impregnated without bending the fibers by using the straight insertion tube in the resin impregnation tank, the disconnection can be prevented without applying an extra load to the fibers. Further, since the size of the resin impregnation tank can be set to a size for supplying the resin to the insertion tube, the amount of resin waste after the impregnation operation can be reduced. Furthermore, the amount of movement of the floating table based on the change in the fiber tension is detected by the reaction force measuring unit, and the tension applying mechanism is controlled, so that the fiber with an appropriate tension can be wound around the work, and the disconnection of the fiber is defective. Can be reduced.

In this embodiment, an example in which the side on which the bobbin supporting mechanism is mounted is floatingly supported is shown. However, the same effect can be obtained even if the bobbin supporting mechanism side is fixed and the fiber winding device side is floatingly supported. Obtainable.

Further, in the present embodiment, the winding of the fiber bundled with a large number of thin glass fibers has been described. However, even when the fiber bundled with a large number of thin metal fibers or a single wire is wound around a work. The same effect can be obtained.

Further, in the present embodiment, an example in which the fiber is wound around the rotor of the motor has been shown. However, when a wire or the like is wound around another work, for example, a coil of a transformer or the like, the disconnection defect is reduced. It is possible to obtain various effects.

[0033]

According to the fiber winding device of the present invention, the bobbin supporting mechanism for rotatably supporting the bobbin wound with the small-diameter fiber has a fiber of the fiber winding mechanism on an arc centered on the guide portion. By moving the bobbin by the pull-out force, no matter which position on the bobbin the fiber is pulled out from, the direction in which the fiber is pulled out is orthogonal to the winding axis of the bobbin, and the fiber is pulled out.
Therefore, it becomes possible to reduce the sliding of the fibers on the bobbin when the fibers are pulled out, and the fibers do not rub against each other due to the sideslip, so that the occurrence of wire breakage can be reduced.

Further, according to the fiber winding device of the present invention, the bobbin supporting mechanism has an arcuate guide plate having an arcuate shape centered on the guide part and having a toothed part in the arcuate part, and an arcuate arc of the arcuate guide plate. And a bobbin supporting portion for supporting the winding shaft of the bobbin, which has a toothed portion which is in point contact with the toothed portion and can mesh with the toothed portion in the circular arc portion, and the bobbin supporting portion is located at the drawing-out position of the thin fiber on the bobbin. Accordingly, the fiber withdrawing force of the fiber winding mechanism moves while meshing with the tooth profile of the arc guide plate.
As a result, the drawing direction of the thin fiber and the winding axis of the bobbin are always orthogonal to each other, and the fiber is drawn. Therefore, it becomes possible to reduce the sliding of the fibers on the bobbin when the fibers are pulled out, and the fibers do not rub against each other due to the sideslip, so that the occurrence of wire breakage can be reduced.

Further, according to the fiber winding device of the present invention, the resin impregnation tank for impregnating the small diameter fiber drawn from the bobbin with the resin is arranged between the guide portion and the fiber winding mechanism, and the resin impregnation is performed. A linear insertion tube that guides the thin fibers into the resin impregnation tank is arranged in the tank. A resin supply hole is provided in this insertion tube to supply the resin. Therefore, the fine fibers can be impregnated with the resin without breaking the wire by passing through the linear insertion tube while keeping the straight state, and at the same time, the size of the resin impregnation tank can be increased. Since the size can be set to the size of supplying resin to the insertion tube,
The amount of resin waste after the impregnation work can be reduced.

Further, according to the fiber winding device of the present invention,
When one of the bobbin support mechanism or the fiber winding mechanism is floatingly supported by the floating support mechanism, and the reaction force measuring unit provided between the bobbin support mechanism and the fiber winding mechanism pulls out the thin fiber from the bobbin support mechanism. The amount of movement due to the reaction force acting between the bobbin supporting mechanism and the fiber winding mechanism is measured. Then, based on the measurement result, the tension controller controls the applied tension of the tension applying mechanism to apply the optimum tension for winding the small diameter fiber. Therefore, since the fiber having an appropriate tension can be wound around the work, the disconnection failure of the fiber can be reduced.
