TECHNICAL 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 bobbin.
[0002]
[Prior art]
As a winding device for manufacturing a deflection yoke, for example, proposals have been made in JP-A-6-325983, JP-A-7-220636, JP-A-5-258669, and the like.
[0003]
In these winding apparatuses, as shown in FIG. 18, a funnel-shaped (flapper-shaped) winding frame (deflection yoke frame) 1 provided with a large-diameter opening 2 and a small-diameter opening 3 at the top and bottom, respectively, is moved not shown. A deflection yoke is formed by winding a wire fed from a free nozzle. 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 along the inner circumference of the bobbin 1 in the vertical direction. Is guided along one of the plurality of slit grooves 4 formed in the longitudinal direction. 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 3 side to the large-diameter opening 2 side, and the wire rod is moved from the slit groove 4 to between the locking pieces 7 provided in the large-diameter opening 2 and the large-diameter opening. It is wound around a circumferential groove 8 formed along the outer periphery of the opening end of the radial opening 2. By sequentially repeating such a winding operation, a deflection coil as shown in FIG. 19 is formed.
[0004]
[Problems to be solved by the invention]
20 and 21 show a tying device (hook device) used for tying work in the openings 2 and 3 (particularly, the small-diameter opening 3 disposed on the lower side) as described above. As shown in these figures, these conventional hook devices 100 and 102 have a structure in which the hooks 101 and 103 hook and guide the wire 9. Since these conventional hook devices 100 and 102 do not particularly include a mechanism for removing the wire 9 from the hook portions 101 and 103, the hook portions 101 and 103 themselves are respectively moved in an arc or circular motion after the tying operation is completed. By moving, the wire 9 is released, and the wire 9 is guided from the release position to the slit groove 4.
[0005]
However, in this release work, 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 cannot be accurately performed. There is. For this reason, the shape and characteristics of the deflection yoke have become unstable by this inaccuracy.
[0006]
Further, 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.
[0007]
However, in this conventional winding device, since the wire feed-out end of the nozzle is fixed at a predetermined angle during the winding operation, for example, if the wire feed-out end faces downward, when the nozzle descends, The wire is fed out in such a manner as to be bent approximately 180 degrees from the wire feed-out end, 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 the instability of the shape and characteristics of the deflection yoke.
[0008]
SUMMARY OF THE INVENTION The present invention has been made in view of such a problem, and is capable of accurately guiding a wire to a predetermined winding position of a winding frame, and improving the accuracy of the shape and characteristics of a coil (deflection yoke). It is intended to provide a device.
[0009]
[Means for Solving the Problems]
The first invention includes a wire supplying device movable in three dimensional directions, the winding apparatus for winding a winding frame the wire fed from the supported nozzle in the wire feeder, the wire of the nozzle co the pivot freely supporting the feeding direction of the wire relative to the feed device, comprising a fixing means for fixing the rotation of the nozzle, when winding the wire on the spool, the wire from the nozzle The nozzle is rotated in accordance with the feeding of the nozzle, and otherwise, the rotation of the nozzle is fixed by the fixing means .
[0010]
According to a second 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. A hook having a hook-shaped tip for locking the wire, a plate member rotatable along the side of the hook, and a driving means for rotating the plate member, and releasing the wire from the hook. When doing so, the wire is pushed out by rotating the plate member.
[0011]
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. 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 hook is rotated so that the wire hitting the plate member is separated from the hook.
[0012]
Function and Effect of the Invention
In the first invention, the nozzle moves along the shape of the coil manufactured together with the wire feeder, but since the nozzle is normally rotatably supported with respect to the wire feeder, the nozzle naturally resists. As a result, the feeding end of the wire is directed toward the side having the smaller number, 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.
[0013]
In the second invention, in a predetermined process 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 wire member is rotated from the hook by the rotation of the plate member. Since the wire is extruded, the release position of the wire from the hook device is stabilized at a predetermined position, and the winding operation can move 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.
[0014]
In the third invention, in the 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 member to move to the plate member. Since the hitting wire is separated from the hook, the release position of the wire from the hook device is stabilized at a predetermined position, and the winding operation can shift from the accurate release position to the next process. it can. 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.
[0015]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
[0016]
FIG. 1 shows the overall configuration of a deflection yoke winding device according to the present invention.
[0017]
The wire 9 unreeled from a spool (not shown) is applied with a predetermined tension by a tension device 11, and then guided to a wire feed device 20 below the tension device 11. The wire feeder 20 is disposed above a desk-shaped reel support 12 provided in a housing of the winding device. The wire 9 fed from a nozzle 21 at the tip of the wire feeder 20 is supported by the reel support. The small-diameter opening 3 is fitted into the hole of the rotating member 12A of the portion 12 from the small-diameter opening 3 side, and is guided to the winding frame (deflection yoke frame) 1 supported on the large-diameter opening 2 side. Here, the bobbin 1 has the same configuration as that shown in FIG. A belt 13 is wound around the outer circumference 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.
[0018]
The wire supply device 20 is supported by the moving device 15 so as to be movable in a three-dimensional direction and rotatable around the central axis of the bobbin 1.
[0019]
More specifically, the moving device 15 includes a cylindrical rotating member 16 arranged substantially coaxially above the bobbin 1. The rotating member 16 is driven to rotate about a rotating shaft 16A by a motor 17. The arm-shaped wire feeder 20 is eccentrically fixed at a predetermined length to the rotating shaft 16A, so that the nozzle 21 at the tip of the wire feeder 20 rotates around the central axis of the bobbin 1 as the rotating member 16 rotates. Revolves. The wire 9 wound on the winding frame 1 passes through the rotating shaft 16A of the rotating member 16 and is guided to the wire feeding device 20 side.
[0020]
The moving device 15 includes four components 15A, 15B, 15C, and 15D. The components 15A and 15B are ball screws 18A, the components 15B and 15C are ball screws 18B, and the components 15C and 15D are ball screws 18C. , Respectively. These three pairs of ball screws 18A, 18B, 18C extend in three axial directions orthogonal to each other, and are driven to rotate by motors 19A, 19B, 19C, respectively.
[0021]
By this rotational drive, the component 15B moves along the ball screw 18A to the component 15A, the component 15C moves along the ball screw 18B to the component 15B, and the component 15D moves along the ball screw 18C. It moves in three different axial directions with respect to 15C. In this case, since the above-mentioned rotating member 16 is rotatably supported by the component 15D, the wire supply device 20 supported by the rotating member 16 can be arbitrarily combined with the rotation of the motors 19A, 19B, and 19C. It is possible to move freely in three-dimensional directions.
[0022]
A support unit 30 that supports the chuck device 39, the upper hook device 40, and the lower hook device 50 is provided below the moving device 15 and beside the reel 1 housed in the reel support hole 12. A moving device 31 for moving the support unit 30 in a three-dimensional direction is disposed on a side of the support unit 30. This moving device 31 is connected to each component by a ball screw extending in three axial directions, similarly to the above-described moving device 15, and the ball screw is rotated by a motor to relatively move each component, thereby winding. 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.
[0023]
FIG. 2 shows the wire feeder 20 in detail.
[0024]
As shown in the figure, the main body 20A of the wire supply device 20 is a hollow arm-shaped member, and the wire 9 guided through the rotating member 16 includes a plurality of pulleys attached to the wire supply device main body 20A. By being guided by 22, it passes through a hollow portion inside the wire rod supply device main body 20 </ b> A and is guided by the nozzle 21.
[0025]
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 distal end of the wire feeder main 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.
[0026]
In this case, the wire 9 is guided between the wire feeder main body 20A and the nozzle support portion 23 side by a pulley, for example, with a sufficient gentle curve (with a sufficient radius) so that excessive friction does not occur. Has become.
[0027]
A gear 25 is fixedly mounted on the base end side of the nozzle support 23 coaxially with the rotation axis of the nozzle support 23. The rotation angle of the nozzle support 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 engagement member 26 is driven by a cylinder 27 provided at a base end of the wire rod supply device 20, and is connected to an end of a rod (not shown) housed inside the wire rod supply device main body 20 </ b> A of the cylinder 27. Things.
[0028]
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.
[0029]
FIG. 3 shows the support unit 30 in detail.
[0030]
As described above, the upper hook device 40 and the lower hook device 50 are supported by the support unit 30 at predetermined intervals vertically. The distance between the upper hook device 40 and the lower hook device 50 is determined in accordance with 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 the wire 9 is guided to the side 2 or the small-diameter opening 3, the other side does not interfere with the bobbin 1.
[0031]
The upper hook device 40 includes 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 the driving of the moving device 31, and the pulley 43 fixed to the shaft 42 at the base end of the hook 41 is driven by the motor 32 to pulley 33, belt It is rotated by being rotationally driven via the switch 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 41 moves along the winding frame 1 by the amount of eccentricity of the center axis and the shaft 42 together with the rotation, and the winding operation is smoothly performed. Can proceed. 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 three-dimensional movement and the rotation. Sometimes, the wire 9 is hooked on the T-shaped tip and guided.
[0032]
On the other hand, the lower hook device 50 includes a hook 51 whose distal end portion 51A is bent like a hook. This hook 51 can also move in the three-dimensional direction by driving the moving device 31, similarly to the hook 41 of the upper hook device 40. The shaft 53 is integrally rotated with the hook fixing portion 52 to which the hook 51 is fixed. The 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 can be used to combine the three-dimensional movement and the rotation to perform a winding operation between the locking pieces 5 and the circumferential groove 6 on the small-diameter opening 3 side of the winding frame 1. The wire 9 is guided by hooking the hook-shaped tip.
[0033]
Further, a plate member 55 is provided on the hook 51 so as to go around on both sides. The plate member 55 is pin-connected to the hook 51 so as to be freely rotatable along the side surface of the hook 51. A shaft 53 is connected to the base end of the plate member 55 via a link 56 and a connecting member 57. Thus, when the shaft 53 is rotated by the motor 32, the plate member 55 rotates together with the hook 51.
[0034]
The shaft 53 is slidable in the axial direction with respect to the hook fixing portion 52. Thus, when the shaft 53 is moved in the axial direction by the motor 58 via the link 59, the connecting member 57 is pushed out, and the plate member 55 is moved in the predetermined direction via the link 56 (the hook-shaped direction of the distal end portion 51A). To rotate. As a result, the wire 9 that has been caught on the distal end portion 51 </ b> A of the hook 51 is pushed upward by the rotating plate member 54, and is released from engagement with the hook 51.
[0035]
In this embodiment, the upper hook device 40 and the lower hook device 50 are configured to move in conjunction with each other for the sake of simplicity of the configuration, but the drive mechanism of the upper hook device 40 and the lower hook device 50 May be provided separately, of course.
[0036]
In the present embodiment, the plate members 55 are arranged on both sides of the hook 51. However, the present invention is not limited to such a form. Only the arrangement may be made. In short, the plate member may have any configuration as long as it can push the wire 9 by rotation.
[0037]
Next, the operation will be described.
[0038]
In order to start the winding operation, first, the end of the wire 9 drawn out 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 is inserted into the slit groove 4 on the inner peripheral surface of the bobbin 1. The wire 9 fed from the nozzle 21 at the tip is wound.
[0039]
In this case, the rotation of the nozzle support 23 is set to be free. As a result, as shown in FIG. 4, the payout 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 23 by a plurality of pulleys 22 provided in the wire feeder 20. Is drawn while drawing a gentle curve, and is fed without resistance from the feeding end of the nozzle 21 at an angle of about 180 degrees. Therefore, no excessive frictional force is generated between the wire 9 and the pay-out end of the nozzle 21, and the tension of the wire 9 is not excessively increased.
[0040]
Since the wire 9 is guided while being gently curved by the pulley 22 in the wire feeder 20, the tension of the wire 9 does not increase due to frictional force.
[0041]
As shown in FIG. 5, when the nozzle 21 is guided to a position where it penetrates the small-diameter opening 3, the engaging member 26 is engaged with the gear 25 at the base end of the nozzle support 23, and the angle of the nozzle support 23 is reduced. Fix at the angle at that time. Then, the hook 51 of the lower hook device 50 is moved, and the hook-shaped tip portion 51A of the hook 51 is hooked on the wire 9 as shown in FIG.
[0042]
Subsequently, as shown in FIG. 7, the hook 51 is raised to guide the wire 9 through the space between the locking pieces 5 and toward the circumferential groove 6. 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 of the distal end portion 51A is oriented so as to face in the direction opposite to the rotation direction of the winding frame 1 so that the wire 9 does not come off from the hook 51.
[0043]
After the wire 9 is guided on the circumferential groove 6 in this manner, the hook 51 is rotated to turn the hook of the distal end portion 51A upward as shown in FIG. 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.
[0044]
When the winding on the small-diameter opening 2 side is completed in this way, as shown in FIG. 11, the wire rod 9 is inserted into the slit groove 4 while the wire feeder 20 is again raised to the large-diameter opening 2 side. Wind. In this case, the rotation of the nozzle support 23 is set to be free again. As a result, the nozzle supporting portion 23 naturally faces downward, and the wire 9 is smoothly fed out from the nozzle 21, so that no extra tension is applied.
[0045]
As shown in FIG. 12, when the nozzle 21 reaches above the large-diameter opening 2, the angle of the nozzle support 23 is fixed in that state. 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.
[0046]
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 is then guided to between the locking pieces 7 through which the wire 9 is to be passed. . 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 supply device 20 is guided again to the inner peripheral side of the winding frame 1, and the winding procedure shown in FIGS. 4 to 15 is repeated.
[0047]
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 freely rotate, so that the nozzle 21 naturally tilts to the angle having the least resistance. Since no excessive frictional force is generated between the nozzle 21 and the wire 9, no excessive tension is generated in the wire 9 at a specific portion of the winding.
[0048]
Further, since the angle of the dispensing end of the nozzle 21 can be fixed via the gear 25 and the engaging member 16, the locking piece 5 is provided at the large-diameter opening 2 or the small-diameter opening 3 of the reel 1. Or, when winding around 7 and around the circumferential groove 6 or 8, the feeding of the wire from the nozzle 21 is not unstable, and accurate winding work can be performed.
[0049]
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, and the wire 9 caught on the hook 51 can be pushed out and released, so that the wire 9 is released. Sometimes, the position is not shifted by being pulled by the hook 51, and it is accurately released to a predetermined position.
[0050]
Therefore, according to the present invention, the wire 9 is accurately wound at the predetermined winding position of the winding frame 1, and the shape and characteristics of the completed deflection yoke are highly accurate.
[0051]
FIG. 17 shows another embodiment of the present invention.
[0052]
As shown, this embodiment differs from the embodiment shown in FIGS. 1 to 3 only in the configuration of the lower hook device 60. 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, and with respect to these plate members 61a and 61b. A hook 62 is rotatably provided.
[0053]
More specifically, plate members 61a and 61b fixed to the plate member fixing portion 65 are provided along the both sides of a portion extending from the approximate 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.
[0054]
On the other hand, the proximal end side of the hook 62 is connected to the shaft 53 via the link 63 and the connecting member 64. When the connecting member 54 is pushed out by the axial movement of the shaft 53, the rotation of the link 63 is performed. At the same time, the hook 62 rotates so that the distal end portion 62A of the hook 62 escapes below the plate members 61a and 61b. In this case, since the wire 9 hooked on the distal end portion 62A does not go below the plate members 61a and 61b by hitting the plate members 61a and 61b, it escapes below the plate members 61a and 61b. The distal end portion 62A is separated from the distal end portion 62A, and the engagement with the distal end portion 62A is released.
[0055]
Note that, also in the present embodiment, the hook 62, the link 63, the connecting member 64, the plate member 61, and the plate member fixing portion 65 of the lower hook device 60 are rotatable together with the shaft portion 53, and the hook tip portion 62A The angle 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.
[0056]
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 member may be formed of one member having a shape in which the plate members 61a and 61b in FIG. 17 are connected on the distal end side (on the hook distal end 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.
