DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deflection yoke winding device, and more particularly to an improvement for accurately guiding a wire to a predetermined winding position of a winding form.

[0002]

2. Description of the Related Art As a winding device for manufacturing a deflection yoke, for example, Japanese Patent Application Laid-Open Nos.
Proposals have been made in JP-A-220636 and JP-A-5-258669.

In these winding devices, a funnel-shaped (flapper-shaped) winding frame (deflection yoke frame) 1 having a large-diameter opening 2 and a small-diameter opening 3 at the top and bottom, respectively, as shown in FIG. A deflection yoke is formed by winding a wire fed from a movable nozzle (not shown). In this case, as the movable nozzle is introduced from the large-diameter opening 2 and descends until it penetrates the small-diameter opening 3, the wire fed from the movable nozzle moves vertically along the inner circumference of the bobbin 1. Is guided along one of the plurality of slit grooves 4 formed in the longitudinal direction. Then, the wire is inserted into a plurality of comb-shaped locking pieces 5 provided in the small-diameter opening 3 and a circumferential groove 6 formed along the outer periphery of the opening end (edge) of the small-diameter opening 3. It is wound using a tying device (hook device). Subsequently, the movable nozzle rises from the small-diameter opening portion 3 side to the large-diameter opening portion 2 side, and the wire is moved from the slit groove 4 to between the locking pieces 7 provided in the large-diameter opening portion 2 and the large It is wound around a circumferential groove 8 formed along the outer periphery of the opening end of the radial opening 2. By repeating such a winding operation sequentially, FIG.
The deflection coil shown in FIG.

[0004]

The problem to be solved by the invention is shown in FIGS.
A tying device (hook device) used for tying work in the openings 2 and 3 (especially the small-diameter opening 3 disposed on the lower side) as described above is shown. As shown, in these conventional hook devices 100, 102, hook portions 101, 10
3, the wire 9 is hooked and guided. And these conventional hook devices 100, 102
Does not particularly have a mechanism for removing the wire rod 9 from the hooks 101 and 103, so that the hook 1
The wire rod 9 is released by causing each of 01 and 103 to move in an arc or a circular motion, and the wire rod 9 is guided from the release position to the slit groove 4.

However, in this release operation, the hooks 101 and 103 inevitably drag the wire 9, so that the release position of the wire 9 becomes unstable, and the guide to the slit groove 4 is accurately performed. You may not be able to do it. For this reason, the shape and characteristics of the deflection yoke have become unstable by the inaccuracy.

In the above-described conventional winding device, the nozzle that feeds out the wire moves in a position where the wire is to be wound, and thus moves in a substantially square shape along the shape of the deflection yoke 10. In this case, a tension is applied to the wire fed from the nozzle, but it is preferable that the tension is stable to a substantially predetermined size in order to accurately wind the wire.

However, in this conventional winding device,
Since the wire feeding end of the nozzle is fixed at a predetermined angle during the winding operation, for example, if the wire feeding end is facing downward, the wire is approximately 180 degrees from the wire feeding end when the nozzle descends. The wire is fed in a bent shape, and the frictional force between the wire and the nozzle increases, so that the tension applied to the wire increases. As described above, in the conventional winding device, the tension applied to the wire changes depending on the winding position, which also causes instability of the shape and characteristics of the deflection yoke.

The present invention has been made in view of such a problem, and can accurately guide a wire to a predetermined winding position of a winding frame, thereby improving the accuracy of the shape and characteristics of a coil (deflection yoke). An object of the present invention is to provide a winding device that can be obtained.

[0009]

According to a first aspect of the present invention, there is provided a wire feeder which is movable in a three-dimensional direction, and winds a wire fed from a nozzle supported by the wire feeder around a winding frame. In the wire device, the wire supply device is provided with fixing means for supporting the nozzle freely rotatable in a normal state and fixing the rotation of the nozzle.

According to a second aspect of the present invention, there is provided a winding device comprising a nozzle movable in a three-dimensional direction, and a hook device for hooking a wire fed from the nozzle and guiding the wire to a predetermined position on a bobbin. The hook device includes a hook having a hook-shaped tip end for locking a wire, a plate member rotatable along a side portion of the hook, and driving means for rotating the plate member. When releasing the wire, the plate member is turned to push the wire.

According to a third aspect of the present invention, there is provided a winding device including a nozzle movable in a three-dimensional direction, and a hook device for hooking a wire fed from the nozzle and guiding the wire to a predetermined position on a bobbin. The hook device includes a hook having a hook-shaped tip for locking a wire, a plate member arranged along a side of the hook, and a driving unit for rotating the hook with respect to the plate member. When the wire is released from the hook, the wire hitting the plate member is separated from the hook by rotating the hook.

[0012]

According to the first aspect of the present invention, the nozzle moves along the shape of the coil manufactured together with the wire feeder, but the nozzle is normally rotatably supported by the wire feeder. Therefore, as a result of the nozzle, the feeding end of the wire is naturally directed to a side having less resistance, so that unnecessary friction does not occur between the nozzle and the wire. Therefore, the tension of the wire fed from the nozzle does not increase unnecessarily during the winding operation, and the winding is performed accurately. As a result, the shape and characteristics of the coil are improved.

In the second invention, in a predetermined step of the winding operation, the wire is guided by being hooked on the hook of the hook device. When the guide process by the hook device is completed, the rotation of the plate member is performed. As a result, the wire is pushed out from the hook, so that the release position of the wire from the hook device is stabilized at a predetermined position, and the winding operation can shift from this accurate release position to the next step. . Therefore, when the wire is released from the hook device, the winding position of the wire does not shift, and the winding is performed accurately. As a result, the shape and characteristics of the coil are improved.

In the third aspect of the present invention, in a predetermined step of the winding operation, the wire is guided by being hooked on the hook of the hook device. When the guide process by the hook device is completed, the rotation of the hook causes the wire to rotate. Since the wire hitting the plate member is separated from the hook, the release position of the wire from the hook device is stabilized at a predetermined position, and the winding work moves from this accurate release position to the next process. can do. Therefore, when the wire is released from the hook device, the winding position of the wire does not shift, and the winding is performed accurately. As a result, the shape and characteristics of the coil are improved.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows the overall configuration of a deflection yoke winding device according to the present invention.

The wire 9 fed from a spool (not shown) is applied with a predetermined tension by a tension device 11, and then guided to a wire supply device 20 below the tension device 11. This wire rod supply device 20
Desk-shaped bobbin supporter 1 provided in the housing of the winding device
2, the wire 9 fed from the nozzle 21 at the tip of the wire feeder 20 fits into the hole opened in the rotating member 12 </ b> A of the reel supporting portion 12 from the small-diameter opening 3 side, and has a large diameter. The opening 2 is guided to a supported winding frame (deflection yoke frame) 1. Here, the bobbin 1 has the same configuration as that shown in FIG. A belt 13 is wound around the outer periphery of a rotating member 12A on which the winding frame 1 is supported, and the winding frame 1 rotates around the central axis together with the rotating member 12A by the circulation of the belt 13 driven by the motor 14. It is supposed to.

The wire feeder 20 is supported by a moving device 15 so as to be movable in a three-dimensional direction and rotatable about the central axis of the bobbin 1.

More specifically, the moving device 15
Includes a cylindrical rotating member 16 disposed substantially coaxially above the winding frame 1. The rotating member 16 is driven to rotate about a rotating shaft 16A by a motor 17. This rotating shaft 1
When the arm-shaped wire feeder 20 is eccentrically fixed at a predetermined length to 6A, the nozzle 21 at the tip of the wire feeder 20 revolves around the central axis of the bobbin 1 with the rotation of the rotating member 16. . The wire 9 wound on the winding frame 1
Are guided through the rotating shaft 16A of the rotating member 16 to the wire feeder 20 side.

The moving device 15 has four components 15
A, 15B, 15C, and 15D.
A and 15B are ball screws 18A.
C is a ball screw 18B, and the components 15C and 15D are connected by a ball screw 18C. The three pairs of ball screws 18A, 18B, 18C extend in three axial directions orthogonal to each other.
It is rotationally driven at 9A, 19B and 19C.

By this rotation, the component 15B is moved along the ball screw 18A to the component 15A, the component 15C is moved along the ball screw 18B to the component 15B, and the component 15D is moved along the ball screw 18C. And moves in three different axial directions with respect to the component 15C. In this case, since the rotating member 16 described above is rotatably supported by the component 15D, the wire supply device 20 supported by the rotating member 16 includes the motors 19A, 19B, and 19C.
Can be freely moved in any three-dimensional direction.

Below the moving device 15 and in the reel supporting hole 1
2, a chuck device 39,
A support unit 30 for supporting the upper hook device 40 and the lower hook device 50 is provided.
A moving device 31 for moving the support unit 30 in a three-dimensional direction is disposed beside the. The moving device 31 is connected to the respective components by a ball screw extending in three axial directions in the same manner as the above-described moving device 15, and the ball screw is rotated by a motor, so that the respective components are relatively moved, so that the winding is performed. The support unit 30, which is the component farthest from the component fixed to the housing of the wire device, can be moved in an arbitrary three-dimensional direction.

FIG. 2 shows the wire feeder 20 in detail.

As shown, the main body 20A of the wire feeder 20 is a hollow arm-shaped member,
The wire 9 guided through the wire feeder main body 2
By being guided by the plurality of pulleys 22 attached to 0A, it passes through the hollow portion inside the wire rod supply device main body 20A and is guided to the nozzle 21.

The nozzle support 23 on which the nozzle 21 is supported is rotatably pin-connected between a pair of brackets 24 provided in parallel with the tip of the wire feeder body 20A. The rotation of the nozzle support portion 23 is free in the state, and the direction of the dispensing end of the nozzle 21 can be freely changed with the rotation of the nozzle support portion 23.

In this case, the wire rod 9 is connected to the wire rod feeder main body 2.
For example, a pulley guides between OA and the nozzle supporting portion 23 side with a sufficiently gentle curve (with a sufficient radius) so that excessive friction does not occur.

At the base end of the nozzle support 23, a gear 25 is fixedly mounted coaxially with the rotation axis of the nozzle support 23. The rotation angle of the nozzle support portion 23 is fixed by engaging the engagement member 26 extending from the wire feeder main body 20A side between the teeth of the gear 25. The engaging member 26 is driven by a cylinder 27 provided at a base end of the wire feeding device 20.
It is connected to a rod end (not shown) housed in the inside of the OA.

The wire feeder 20 is equipped with a wire holding mechanism (not shown) so that the wire 9 does not come off from the wire feeder 20.

FIG. 3 shows the support unit 30 in detail.

As described above, the upper hook device 40 and the lower hook device 50 are supported on the support unit 30 at predetermined intervals above and below each other. The distance between the upper hook device 40 and the lower hook device 50 is determined according to the size of the bobbin 1. One of the upper hook device 40 and the lower hook device 50 is connected to the large-diameter opening of the bobbin 1. When guiding the wire 9 to the 2 side or the small-diameter opening 3 side,
The other side does not interfere with the bobbin 1.

The upper hook device 40 has a hook 41 having a substantially T-shaped tip. The hook 41 can be moved in an arbitrary three-dimensional direction together with the support unit 30 by driving the moving device 31, and a shaft 42 at the base end of the hook 41.
Is fixed to the pulley 3 by the motor 32.
3. It is rotated by being driven to rotate via the belt 34, so that the direction of the T-shaped portion at the tip can be changed. In this case, the center axis of the hook 41 and the axis 42 are eccentrically attached. Accordingly, if the direction of rotation of the hook 41 is made to correspond to the traveling direction of the winding, the hook 4
1 is the winding frame 1 by the amount of eccentricity of the center axis and the shaft 42 with the rotation.
And the winding operation can proceed smoothly. The upper hook device 40 winds the space between the locking pieces 7 and the circumferential groove 8 on the large-diameter opening 2 side of the winding frame 1 by such a combination of the movement and the rotation in the three-dimensional direction. Sometimes, the wire 9 is hooked on the T-shaped tip to guide the wire.

On the other hand, the lower hook device 50 has a tip 51
A has a hook 51 bent into a hook shape. This hook 51 is also similar to the hook 41 of the upper hook device 40,
It can move in a three-dimensional direction by driving the moving device 31. A shaft 53 is integrally rotated with a hook fixing portion 52 to which the hook 51 is fixed. A pulley 43 fixed to the shaft 53 is driven by the motor 32 via the belt 34 and the pulley 33. By being driven to rotate, the angle of the hook-shaped portion at the tip can be changed. The lower hook device 50 moves the locking piece 5 on the small-diameter opening 3 side of the bobbin 1 by the movement combining the three-dimensional movement and the rotation.
The wire 9 is hooked on the hook-shaped tip when the wire is wound around the gap or the circumferential groove 6 and guided.

Further, a plate member 55 is provided on the hook 51 so as to go around on both sides.
The hook 51 is pin-connected to the hook 51 so as to be freely rotatable along the side surface thereof. A shaft 53 is connected to the base end of the plate member 55 via a link 56 and a connecting member 57. Thereby, the shaft 53 is connected to the motor 3
When rotated by 2, the plate member 55 rotates together with the hook 51.

The shaft 53 is slidable in the axial direction with respect to the hook fixing portion 52. Thereby, the shaft 5
When the motor 3 is moved by the motor 58 in the axial direction via the link 59, the connecting member 57 is pushed out, and the plate member 55 rotates in the predetermined direction (the hook-shaped direction of the distal end portion 51A) via the link 56. Thereby, the tip portion 51 of the hook 51
The wire 9 caught on A is the plate member 5 that has turned.
4 pushes upward and is released from engagement with the hook 51.

In the present embodiment, the upper hook device 40 and the lower hook device 50 move in conjunction with each other for the sake of simplicity of the structure. It is needless to say that the drive mechanisms may be separately provided.

In the present embodiment, the plate members 55 are arranged on both sides of the hooks 51. However, the present invention is not limited to such a form. May be arranged only on one side. In short, the plate member may have any configuration as long as it can push the wire 9 by rotation.

Next, the operation will be described.

To start the winding operation, first, the end of the wire 9 fed from the nozzle 21 at the tip of the wire feeder 20 is gripped and fixed by the chuck device 39. In this state, as shown in FIG. 4, the wire feeder 20 is introduced from the large-diameter opening 2 of the bobbin 1 and lowered, and the wire feeder 20 is inserted into the slit groove 4 on the inner peripheral surface of the bobbin 1. Tip nozzle 2
The wire 9 fed from 1 is wound.

In this case, the rotation of the nozzle support 23 is set to be free. Thereby, as shown in FIG. 4, the pay-out end of the nozzle 21 naturally faces upward, and the wire 9 is moved from the wire feeder main body 20A to the nozzle support portion 23 by a plurality of pulleys 22 provided in the wire feeder 20. To
The nozzle 21 is guided while drawing a gentle curve, and is fed out from the delivery end of the nozzle 21 at an angle of about 180 degrees without resistance. Therefore, no excessive frictional force is generated between the wire 9 and the pay-out end of the nozzle 21, and the wire 9
The tension will not increase too much.

Since the wire 9 is guided while being smoothly curved by the pulley 22 in the wire feeder 20, the tension of the wire 9 does not increase due to frictional force.

As shown in FIG. 5, when the nozzle 21 is guided to a position penetrating the small-diameter opening 3, the engaging member 2
6 is engaged with the gear 25 at the base end of the nozzle support 23, and the angle of the nozzle support 23 is fixed at the angle at that time. Then, the hook 51 of the lower hook device 50 is moved, and FIG.
As shown in (1), the hook-shaped tip portion 51A of the hook 51 is hooked on the wire 9.

Subsequently, as shown in FIG. 7, the hook 51 is raised to guide the wire 9 through the space between the locking pieces 5 to the circumferential groove 6 side. Then, as shown in FIG. 8, the winding frame 1 is rotated by itself to perform winding along the circumferential groove 6, and then the hook 51 is moved upward between the locking pieces 5 through which the wire 9 is to be passed. To move. At this time, the hook 51 is connected to the tip 51A.
Of the wire rod 9 is oriented in the direction opposite to the rotation direction of the winding frame 1 so that the wire 9 does not come off the hook 51.

After the wire 9 is guided on the circumferential groove 6 as described above, the hook 51 is rotated as shown in FIG.
Turn the hook of 1A upward. Then, as shown in FIG. 10, the wire 9 is pushed upward by rotating the plate member 55, and the engagement between the hook 51 and the wire 9 is released. By releasing the wire 9 in this manner, the wire 9 is accurately guided between the locking pieces 5 below the release position without being dragged by the hook 51.

When the winding on the small-diameter opening 2 side is completed in this way, as shown in FIG.
The wire 9 is wound around the slit groove 4 while raising 0 toward the large-diameter opening 2. In this case, the nozzle support 23
Is free again. As a result, the nozzle support 23 naturally faces downward, and the wire 9 is smoothly fed out of the nozzle 21, so that no extra tension is applied.

As shown in FIG. 12, when the nozzle 21 reaches the position above the large-diameter opening 2, the nozzle support 23
Fix the angle of. Then, as shown in FIG. 13, the wire 9 is hooked and guided by the hook 41, and the wire 9 is guided between the locking pieces 7.

In this state, when the winding frame 1 is rotated as shown in FIG. 14, the wire 9 is wound along the circumferential groove 9, and then between the locking pieces 7 through which the wire 9 is to be passed. Led to. At this time, the wire 9 is naturally released from the hook 41 above the wire 9. Thereafter, as shown in FIG. 16, the wire rod supply device 20 is guided again to the inner peripheral side of the bobbin 1, and the winding procedure shown in FIGS. 4 to 15 is repeated.

As described above, according to the present invention, when the wire 9 is wound around the slit groove 4, the pay-out end of the nozzle 21 can be freely rotated.
1 is naturally inclined at the angle having the least resistance, and no excessive frictional force is generated between the nozzle 21 and the wire 9.
Does not cause excessive tension at a specific portion of the winding.

The angle of the dispensing end of the nozzle 21 is
Since it can be fixed via the gear 25 and the engaging member 16, in the large-diameter opening 2 or the small-diameter opening 3 of the winding frame 1, between the locking pieces 5 or 7 and the circumferential groove 6 or 8. When winding the wire, the feeding of the wire from the nozzle 21 is not unstable, and an accurate winding operation can be performed.

Further, a rotatable plate member 55 is provided on the side of the hook 51 for performing the winding operation in the small-diameter opening 3 so that the wire 9 hooked on the hook 51 can be pushed out and released. 9 is not displaced by being pulled by the hook 51 at the time of release,
Released exactly in place.

Therefore, according to the present invention, the wire 9 is accurately wound at a predetermined winding position of the winding frame 1, and the shape and characteristics of the completed deflection yoke are highly accurate.

FIG. 17 shows another embodiment of the present invention.

As shown, in this embodiment,
Only the configuration of the lower hook device 60 is different from the embodiment shown in FIGS. That is, in the lower hook device 60, a pair of plate members 61a and 61b are fixed to the plate member fixing portion 65 so as to be located on both sides of the hook 62A.
A hook 62 is provided rotatably with respect to 1b.

More specifically, plate members 61a and 61b fixed to the plate member fixing portion 65 are provided along the both sides at a portion extending from substantially the center of the hook 62 to the hook-shaped tip portion 62A. The hook 62 is rotatable with respect to the plate member 61 around a rotation fulcrum provided substantially near the center.

On the other hand, the base end of the hook 62 is
When the connecting member 54 is pushed out by the axial movement of the shaft portion 53, the link 63 is rotated and the distal end portion 62A of the hook 62 is connected to the plate member 61a. , 61b so as to escape below. In this case, the tip 6
The wire rod 9 caught on the 2A becomes the plate members 61a, 61a.
b, so that it does not go below the plate members 61a, 61b, it is separated from the tip portion 62A that escapes below the plate members 61a, 61b, and the tip portion 6
2A is disengaged.

In this embodiment, too, the hook 62, the link 63, the connecting member 64 of the lower hook device 60,
The plate member 61 and the plate member fixing portion 65 are rotatable together with the shaft portion 53, and the angle of the hook tip portion 62A can be changed as in the embodiment shown in FIG. Further, the hook 62 can be moved in the three-dimensional direction together with the lower hook device 60 as in the embodiment shown in FIG.

Further, in the present embodiment, the plate member is constituted by the pair of plate members 61a and 61b on both sides of the hook 62, but the present invention is not limited to such a form. For example, the plate members are plate members 61a and 61 in FIG.
1b may be composed of one member having a shape connected on the tip side (the hook tip portion 62A side). Further, a configuration including only one of the plate members 61a and 61b in FIG. 17 may be adopted. As described above, the plate member may be of any form as long as it can hit the wire 9 and separate the hook 62 and the wire 9 when the hook 62 moves.
