Description

  The present invention relates to a winding device suitable for winding a winding used in a static induction electrical device such as a transformer around a winding frame, and a winding method for winding a winding using the winding device. is there.

  A winding device for winding a transformer winding includes, for example, a winding frame driving device having a main shaft that concentrically holds a winding frame and a rotation driving device that rotationally drives the main shaft, as shown in Patent Document 1 And a traverse mechanism disposed between the supply source of the winding conductor and the reel driving device. The traverse mechanism traverses the winding conductor so as to appropriately change the supply position of the winding conductor to the winding frame according to the winding structure, with the direction parallel to the axis of the main shaft as the traverse direction. When the windings of each layer are continuously aligned and wound from one end of the winding frame to the other end, the traversing direction of the winding conductor is usually constant in the process of winding the windings of each layer. Therefore, the traverse does not become complicated, but depending on the winding structure, the traverse and the traverse stop are repeated in a short cycle, and it is necessary to perform a complicated traverse in which the traverse direction is finely reversed. .

  For example, in a transformer winding in which conductors with insulation coating are wound in multiple layers without inserting insulating paper between layers, the voltage applied between adjacent turns in each layer and between adjacent turns between layers is not excessive. In order to improve the position of the series of turns, the position where the conductor is arranged at every turn or every few turns changes finely before and after the reel in the axial direction of the reel. Need to reverse direction.

  As an example, FIG. 12 shows a winding structure of a 60-degree winding transformer winding wound so that the angle formed by the axial end faces of the winding is 60 degrees, as shown in Patent Document 1. Some are shown. In the figure, a circle indicates a cross section of the winding conductor, and a number displayed in the circle indicates the number of turns from the start of winding. P indicates the winding pitch.

  In the winding shown in FIG. 12, first, the first to fourth turns of the winding belong to the lowermost winding while shifting the supply position of the winding conductor to the winding frame by 1 pitch in the left direction. After winding continuously as a turn, the supply position of the winding conductor to the winding frame is returned to the right by 1.5 pitches, and the fifth turn conductor is passed between the second turn conductor and the third turn conductor. Subsequently, the conductor of the 6th turn is positioned between the conductor of the 2nd turn and the conductor of the 1st turn, and these 5th turn and 6th turn are continuously wound as turns belonging to the second layer winding. . Next, the winding conductor supply position was shifted to the left by 1/2 pitch, and the seventh turn was wound as the first turn of the third layer winding between the fifth turn conductor and the sixth turn conductor. Thereafter, the supply position of the winding conductor is shifted by 1.5 pitches to the left, and the eighth turn is wound between the third turn and the fourth turn surface as a turn belonging to the second layer winding. Next, the winding conductor supply position is shifted by 1.5 pitches to the left, and the ninth turn is wound as a turn belonging to the lowermost winding next to the fourth turn, and then the winding supply position is set to 1 to the left. Turn the turn and roll the 10th turn next to the 9th turn. The conductors constituting the series of turns are arranged so as to be stacked in the order shown below, and wound so that the outline of the winding end face forms 60 degrees with respect to the winding center axis on the longitudinal section of the winding. I will turn. In this winding, by devising the arrangement of a series of turns so that the voltage applied between adjacent turns is limited to a voltage of 7 turns or less, it is possible to obtain a predetermined without inserting an interlayer insulating paper between layers. Has dielectric strength. This type of winding is already widely known as shown in Patent Document 2, Patent Document 3 and Patent Document 4.

  When winding the winding as described above, for example, a rectangular winding frame as shown in FIG. 13 is used. FIG. 13 (A) is a front view schematically showing the shape of the reel, (B) is a side view of (A), and (C) is a top view of (A). When winding the above-described winding, it is necessary to accurately determine the position of the conductor of each turn of the lowermost winding. Therefore, in the illustrated winding frame, the cross-sectional contour shape is rectangular. The four corners of the reel body a have grooves b1 for fitting and positioning a part of the winding conductors of the respective turns constituting the lowermost layer windings by the number of turns of the lowermost layer windings. A conductor positioning portion b is provided.

  In this type of winding, it is necessary to wind the winding conductor around the winding frame to form each turn, and then cross the winding conductor to form the next turn. Since the winding swells when the conductor crosses, the crossing portion is provided so as to be concentrated on one side of the winding frame in order to reduce the bulging surface in the finished winding state.

  When winding this type of winding, for example, with the transition portion positioned on one side a4 of the winding frame, the winding conductor of each turn is placed at the same position in the axial direction of the winding frame at the three sides a1 to 1 of the winding frame. After winding along a3, while winding around the remaining side a4 of the winding frame, according to the turn arrangement as shown in FIG. Yes. That is, in the process of winding each turn, when winding the winding conductor around the three sides a1 to a3 of the winding frame, the position is fixed at a predetermined position without traversing the winding conductor. While the wire conductor is wound around one side a4 of the winding frame, the winding conductor is traversed and crossed to the position where the next turn is provided, and the next turn is wound around the three sides a1 to a3 of the winding frame. As shown in FIG. 14, the winding C wound in this way has only one side face C4 of the four side faces C1 to C4 along the four sides a1 to a4 of the winding frame. Due to the presence of the crossed portion, it has a shape bulging outward.

In the process of winding the winding as described above, the traverse of the winding conductor and the stop of the traverse are repeated in a short cycle, and the traverse direction is finely reversed in accordance with the change in the crossing direction of the winding conductor. Will be.

  As described above, when it is necessary to cause the traverse mechanism of the winding apparatus to perform a complicated traverse operation, the direction in which the winding conductor is fed out from the traverse mechanism should be easily changed. Is preferred.

  Further, when the winding conductor sent out from the traverse mechanism is transferred to the winding frame and wound around the winding frame, the winding conductor sent out from the traverse mechanism is bent in the axial direction of the winding frame (wound around the winding frame). At this time, it is preferable not to have a curl to bend in the axial direction of the reel. If the winding conductor sent out from the traverse mechanism is bent in the axial direction of the winding frame, the winding conductor wound around the winding frame is curved on the winding frame, so that the winding cannot be wound neatly. . In particular, when winding a winding having a complicated winding structure as described above, in order to accurately cross the winding conductor at the connecting portion of the winding conductor, the winding conductor is moved in the axial direction of the winding frame. It is preferable not to bend the crease. If the winding conductor is bent in the axial direction of the winding frame, when the winding conductor of each turn is moved to the position where the winding conductor of the next turn is placed, the winding conductor is placed in an accurate position. Since it becomes impossible to sit down and the arrangement of the winding conductors is often lost, there is a high probability that the windings being wound will be defective, and the yield of the manufactured windings will be avoided. I can't.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a winding device that can easily handle winding of a winding having a complicated winding structure by providing various movements of a traverse mechanism.

  Another object of the present invention is to provide a winding device capable of preventing the winding conductor from being bent in the axial direction of the winding frame when the winding conductor is sent out from the traverse mechanism. There is.

  Another object of the present invention is to provide a winding method capable of preventing the winding conductor from being bent in the axial direction of the winding frame when the winding conductor is sent out from the traverse mechanism. There is.

  The present invention is disposed between a winding frame driving device having a main shaft that concentrically holds the winding frame and a rotation driving device that rotationally drives the main shaft, and between a winding conductor supply source and the winding frame driving device. The present invention is directed to a winding apparatus including a traverse mechanism that traverses a winding conductor wound around a winding frame with a direction parallel to the axis of the main shaft as a traverse direction.

  In the present invention, the traverse mechanism has a first slider provided so as to slide in the traverse direction along the reference plane, with one plane including the central axis of the main shaft as a reference plane, and the first slider And a second slider provided so as to slide in the traverse direction along the reference plane, and the first and second sliders reciprocally using the first motor and the second motor as drive sources, respectively. First and second feeding mechanisms for linear displacement, and a rotation guide axis that extends in a direction perpendicular to the reference plane, provided at the tip with line guide means for determining the feeding position of the winding conductor that is fed to the reel side. A pin that is pivotally supported by the first slider so as to be pivotable to the center and extends in a direction perpendicular to the reference plane, and the pin is slidably fitted. And a traverse head coupled to the second slider via a coupling mechanism having a lot, and the winding conductor supplied from the source of the winding conductor to the rear end side of the traverse head extends along the traverse head. It is configured such that it is guided along the straight conductor supply line to the front end side of the traverse head and sent out from the line guide means to the reel side. With such a configuration, the first motor and the second motor are controlled to cause the traverse head to generate a linear displacement in the traverse direction and a rotational displacement about the rotational center axis. Can do.

  If comprised as mentioned above, by controlling a 1st motor and a 2nd motor, the linear displacement to a traverse direction and the rotation displacement centering on the rotation center axis line can be produced in a traverse head. Therefore, the movement of the traverse mechanism can be varied, and it is easy to handle windings with complicated winding structures that require frequent reversal of the traverse direction when winding the windings. can do.

  Further, if configured as described above, by controlling the first motor and the second motor, it is possible to control the conductor supply line so as to always be directed in the direction of feeding the winding conductor from the traverse mechanism. It is possible to prevent the winding conductor sent out from the traverse mechanism from being bent or bent in the axial direction of the winding frame. Therefore, when the winding conductor of each turn is passed from the lower layer to the upper layer and from the upper layer to the lower layer, the winding conductor can be accurately passed to a predetermined destination, and the winding conductor fails to pass. Thus, the yield of the manufactured winding can be improved.

  In a preferred aspect of the present invention, the wire guide means includes a conductor supply line, and is arranged side by side in a state perpendicular to the plane perpendicular to the reference plane and with the rotation center axis oriented, and is freely rotatable on the traverse head. A pair of wire guide rollers supported by the wire guide roller is provided, and the winding conductor supplied along the conductor supply line is attached to the outer periphery of the upper wire guide roller from the upper part of the one wire guide roller arranged on the upper side. Then, the wire conductor is fed to the line guide roller disposed on the lower side through the gap between the pair of line guide rollers. It is configured to be transferred to the reel driving device side from the lower part of the lower guide roller while being bent to the other side along the outer periphery of the lower line guide roller.

  Note that one of the pair of line guide rollers only needs to be disposed above the other, and does not necessarily have to be arranged in the vertical direction. That is, the pair of line guide rollers may be provided so as to be lined up and down along a direction inclined with respect to the vertical direction.

  As described above, the line guide means is constituted by a pair of line guide rollers arranged vertically, and the winding conductor supplied along the conductor supply line is connected to the upper line guide roller from the upper part of the upper line guide roller. The wire conductor is transferred to the lower wire guide roller through the gap between the pair of wire guide rollers after being fed over the circumference of the upper wire guide roller while bending to one side along the outer periphery. If it is configured so that it is fed from the lower part of the lower guide roller to the reel drive unit side while being bent to the other side along the outer periphery of the lower line guide roller, the winding conductor is lowered. In the process of passing through the outer periphery of the wire guide roller on the side, a bending ridge that tends to bend in a direction that protrudes toward the winding frame side when placed on the winding frame is slightly attached. When winding a winding on a winding frame that has a rectangular cross-sectional profile and has four flat surfaces, supplying the winding conductor with such a bending flaw By applying an appropriate tension to the winding conductor, it is possible to wind the winding conductor in close contact with the winding frame without lifting from the winding frame.

  The present invention is also arranged between a winding frame driving device having a main shaft that concentrically holds the winding frame and a rotation driving device that rotationally drives the main shaft, and between a winding conductor supply source and the winding frame driving device. And a traverse mechanism that traverses the winding conductor wound around the winding frame with the direction parallel to the axis of the main axis as the traverse direction, and traverses the winding conductor wound around the winding frame. The object is a winding method in which a winding conductor is wound around a winding frame while traversing by a mechanism.

  In the present invention, the winding device having the above-described configuration is used, and the angle formed by the straight line along the winding conductor fed from the traverse mechanism to the winding frame side with respect to the plane orthogonal to the main axis is the lead angle. The first motor and the second motor keep the state where the conductor supply line and the winding conductor sent out from the traverse mechanism are positioned on a plane inclined by an angle equal to the lead angle with respect to a plane orthogonal to the axis of the main shaft. The winding conductor is traversed by a traverse mechanism while controlling the motor.

  According to the above method, since the winding conductor is traversed in a state where the conductor supply line is always directed in the direction in which the winding conductor is sent from the traverse mechanism, winding winding proceeds. The winding conductor supplied to the winding frame can be prevented from being bent in the axial direction of the winding frame, and the winding conductor can be prevented from bending on the winding frame. The probability of failure in crossing can be reduced and the yield of the manufactured winding can be increased.

  According to the winding device of the present invention, by controlling the first motor and the second motor, a linear displacement in the traverse direction and a rotational displacement about the rotational central axis are generated in the traverse head. The traverse mechanism can be used in a variety of ways, and when winding, it is necessary to frequently reverse the traverse direction when winding. Can also be easily accommodated.

  According to the winding device of the present invention, the first motor and the second motor are controlled so that the conductor supply line is always directed in the direction of feeding the winding conductor from the traverse mechanism. Therefore, it is possible to prevent the winding conductor sent out from the traverse mechanism from being bent in the axial direction of the winding frame. Therefore, when the winding conductor of each turn is passed from the lower layer to the upper layer and from the upper layer to the lower layer, the winding conductor can be accurately passed to a predetermined destination, and the winding conductor fails to pass. Thus, the yield of the manufactured winding can be improved.

  In the winding apparatus according to the present invention, the line guide means is constituted by a pair of line guide rollers arranged vertically, and the winding conductor supplied along the conductor supply line is arranged from the upper part of the line guide roller arranged on the upper side. The wire conductor is passed through the gap between the pair of wire guide rollers after being fed over almost half the circumference of the upper wire guide roller while being bent to one side along the outer periphery of the upper wire guide roller. It is made to shift to the line guide roller arranged on the side, and is sent to the reel driving device side from the lower part of the lower guide roller while bending to the other side along the outer periphery of the lower line guide roller. In this case, when the winding conductor passes through the outer periphery of the lower line guide roller, when it is arranged on the winding frame, a slight bending rod that tends to bend in the direction that protrudes toward the winding frame side is formed. Because it can be attached to the winding conductor When winding a winding on a winding frame having a rectangular cross-sectional profile, the winding conductor is prevented from being lifted from the winding frame, and the winding conductor is closely attached to the winding frame. be able to.

  According to the winding method of the present invention, the conductor supply line is always directed in the direction in which the winding conductor is sent from the traverse mechanism (the conductor supply line and the straight line along the direction in which the winding conductor is sent are in the same plane. Since the winding conductor is traversed and the winding turns, the winding conductor supplied from the traverse mechanism to the winding frame tends to bend in the axial direction of the winding frame. Prevents bending wrinkles, prevents the winding conductor from curving on the winding frame, reduces the chance of failure to cross the winding conductor, and increases the yield of the manufactured winding be able to.

When the first slider 11 and the second slider 12 are linearly displaced to one side at the same speed along the traverse direction, the first and second motors 13 and 14 are moved at a constant speed in the other direction. When rotated, the first slider 11 and the second slider 12 are linearly displaced toward the other side at the same speed along the traverse direction.

  When the first motor 13 and the second motor 14 are rotated in the same direction at different speeds, and when the first motor 13 and the second motor 14 are rotated in different directions, the first slider 11 and the second slider 13 are displaced relative to each other in the thrust direction, so that the movable plate 20a can be rotated in either direction around the rotation central axis 27. Yes. That is, by controlling the first motor 13 and the second motor 14, it is possible to cause the traverse head 20 to generate a linear displacement in the traverse direction and a rotational displacement about the rotational center axis OO. It is configured.

  When winding the winding around the winding frame 8, after fixing the tip of the winding conductor W drawn from the winding conductor supply source via the wire guide rollers 31 and 17 of the traverse head 20 to the winding frame 8. The traverse head 20 is controlled in a predetermined manner while controlling the first motor 13 and the second motor 14 so that the winding frame 8 is rotated and the conductor supply line L is always directed in the direction in which the winding conductor is sent out from the traverse mechanism. Displace in the traverse direction. In this specification, “directing the conductor supply line L in the direction of feeding the winding conductor from the traverse mechanism” means that the conductor supply line and the straight line along which the winding conductor sent from the traverse mechanism is located on the same plane. Means that.

  When the winding is wound by the winding method according to the present invention, the angle formed by the straight line along the feeding direction of the winding conductor sent from the traverse mechanism to the winding frame side with respect to the plane perpendicular to the main axis is determined. And a first motor so as to keep the conductor supply line and the winding conductor fed from the traverse mechanism on a plane inclined by an angle equal to the lead angle with respect to a plane perpendicular to the axis of the main shaft. The winding conductor is traversed by the traverse mechanism while controlling the motor and the second motor.

  For example, when winding a winding having a structure as shown in FIG. 12, the traverse head is wound while the winding conductor W of each turn is wound around one side of the winding frame (for example, the short side a4 in FIG. 13). 20 is traversed by a predetermined pitch in a predetermined traverse direction, and the winding conductor W of each turn is formed at a corner portion between one side a4 and the next side a1 of the winding frame as shown in FIG. Sit in the position. When traversing the winding conductor W, as described above, the axis direction of the main shaft is set so that the conductor supply line L is directed in the direction in which the winding conductor W is sent from the traverse mechanism 10 (from the line guide means 17). The position of the traverse head 20 and the inclination angle of the traverse head 20 are controlled. The inclination angle of the traverse head 20 can be defined as, for example, an angle formed by a plane that includes the conductor supply line L and that is orthogonal to the reference plane with respect to a plane that is orthogonal to the central axis of the main shaft 6.

  As an example, FIGS. 5 to 10 show the movement of the traverse head 20 in the process of winding the first turn to the sixth turn of the winding shown in FIG. 12 by the winding method according to the present invention. Here, for convenience of explanation, a traverse in the left direction in the drawing along the axis of the main shaft 6 is referred to as a forward traverse, and a traverse in the right direction in the drawing is referred to as a reverse traverse.

  FIG. 5 shows a state in which the first turn portion of the winding conductor is attached to the long side portion of the winding frame 8, and FIG. 6 shows the winding conductor W at a predetermined lead angle θ on one short side of the winding frame 8. It shows a state where the vehicle is traversed in the forward direction with a crossing from the position of the first turn to the position of the second turn. 7 and 8 show a state in which the fourth turn is wound around the long side portion and the short side portion of the winding frame 8, respectively. FIG. 9 shows the winding conductor W at one short side a4 of the winding frame 8. A state is shown in which the winding is traversed in the reverse direction by one pitch and passed from the position of the fourth turn to the position of the fifth turn (position shown in FIG. 12). Further, FIG. 10 shows a state in which the winding conductor is traversed in the reverse direction at one short side a4 of the winding frame 8 so as to extend from the fifth turn position to the sixth turn position.

  FIG. 11 shows a state where the winding is wound by a conventional winding device configured such that the traverse head 20 can be displaced only in the axial direction of the main shaft. As shown in the figure, when the traverse head 20 is configured to be displaced only in the axial direction of the main shaft 6, the direction in which the winding conductor is fed from the wire guide means 17 is the conductor supply line L. In order to form an angle α with respect to the winding conductor W, when the winding conductor W is moved with a lead angle, the winding conductor W has a bending wrinkle that tends to bend in the axial direction of the winding frame. The winding conductor W is curved. In this way, if the winding conductor wound around the outer periphery of the winding frame is curved, the winding conductor may not be accurately passed to the target position, and there is a probability that the winding conductor will fail to cross. Get higher.

  On the other hand, in the present invention, when the winding conductor is moved with the lead angle θ, the first motor 13 and the second motor 14 are controlled so that the conductor supply line L in the traverse head is Since the inclination angle of the traverse head 20 can be controlled so that the winding conductor is sent out from the traverse mechanism, the winding conductor W fed from the wire guide means 17 is curved in the axial direction of the winding frame 8. It is possible to prevent the bending wrinkles to be made, and to reduce the probability of failure in crossing the winding conductor.

  In the present invention, the position of the traverse head 20 in the traverse direction and the inclination angle of the traverse head 20 are controlled by controlling the first motor 13 and the second motor 14. The control of the first motor 13 and the second motor 14 includes, for example, a target position of the traverse head when crossing the winding conductors of each turn, and a traverse head 20 when traversing the winding conductors of each turn. The first motor 13 and the first motor 13 that are required to calculate the target tilt angle in advance and to match the position and tilt angle of the traverse head when winding each turn with the calculated target position and target tilt angle, respectively. The amount of rotation and the direction of rotation of the second motor 14 are calculated and stored, and the first motor 13 and the second motor 14 are stored when the series of winding turns are wound. Control may be performed so as to rotate by the amount of rotation stored in the direction.

  In the above description, the winding conductor is crossed at the short side portion of the winding frame. However, the present invention can be applied to the case where the winding conductor is crossed at the long side portion of the winding frame. is there.

However, the slot is provided on the slider 12 side, and the pin fitted in the slot is provided. You may make it fix to the movable plate 20a side.

The lower surface of the plate is brought into contact. In order to simplify the structure of the apparatus and to configure the apparatus compactly, it is preferable to configure in this way, but in the present invention, the movable plate 20a is rotatably supported by the first slider 11, The second slider 12 and the movable plate 20a may be coupled via a coupling mechanism comprising a slot and a pin slidably fitted in the slot, and the upper surfaces of the first slider and the second slider are not necessarily flush with each other. There is no need to be on top. Further, the first slider 11 and the second slider 12 may be arranged with their positions shifted in a direction orthogonal to the reference plane. The movable plate 20 a is formed in an appropriate shape according to the configuration of the first slider 11 and the second slider 12.

  In the above embodiment, the horizontal plane including the central axis of the main axis (the central axis of the reel) is used as the reference plane. However, a plane including the central axis of the main axis and inclined with respect to the horizontal plane may be used as the reference plane.
