Description

  The present invention relates to a winding apparatus and a winding method for mainly manufacturing a cup-shaped coil used for a coreless motor.

  In recent years, a cup type coil is used for a coreless motor, and the cup type coil is manufactured by a conventionally known dedicated automatic winding machine. The automatic winding machine includes a winding jig for winding a wire material which is a coil material, a nozzle which reciprocates in the axial direction of the winding jig while feeding the wire toward the winding jig, and an axial direction of the winding jig. It is supposed that it has a pair of guide pieces arranged on both sides at a distance (for example, refer to Patent Document 1).

  In this automatic winding machine, the wire rod is fed while reciprocating the nozzle in the axial direction of the winding jig, and the winding jig and the guide piece are rotated in the same direction according to the feeding of the wire rod, and the wire rod is wound on the winding jig. It is configured to be wound on. The wire supplied around the winding jig is configured by the pair of guide pieces to be a triangular wave with the guide pieces at the top around the winding jig.

Japanese Patent Application Laid-Open No. 55-100045

  However, in the above conventional winding apparatus in which the wire is drawn out while linearly reciprocating the nozzle in the axial direction of the winding jig and the wire is formed into a triangular wave around the winding jig, the wire is immediately folded back at the guide piece. There is a problem that the outside diameter at both ends of the cup-shaped coil obtained by expansion of the wire rod to be folded is enlarged.

  Further, the device for reciprocating the nozzle linearly in the axial direction of the winding jig requires, in addition to the nozzle, a holder for holding the nozzle, a rail for reciprocating the holder, and a moving mechanism. The mass of the member around the nozzle that reciprocates increases, and it becomes difficult to quickly reciprocate the nozzle due to the increase of the inertial force, and the reciprocation is quickly performed to shorten the time for winding. There was also a defect that caused limitations.

  Furthermore, when trying to wind a new triangular wave wire around a winding jig adjacent to a triangular wave wire previously formed, the rotational speed of the pair of guide pieces and the rotational speed of the winding jig differ, for example, For each rotation of the winding jig, it is necessary to advance the pair of guide pieces by the thickness of the wire.

  However, as shown in FIG. 13, while advancing the pair of guide pieces 2, 2 by the thickness of the wire 3, the wire 3 is triangular wave while linearly reciprocating the nozzle 5 in the axial direction of the winding jig 4. However, since the nozzle 5 needs to move to the outside of the pair of guide pieces 2 and 2, the nozzle 5 does not necessarily move adjacent to the triangular wave formed previously.

  Therefore, in the conventional winding machine in which the wire 3 is drawn out while reciprocating the nozzle 5 in the axial direction of the winding jig 4, a gap is generated between it and the triangular wave formed earlier, and winding around the winding jig 4 is performed. There is a problem that so-called alignment winding becomes relatively difficult, in which the wire 3 to be attached is in close contact with the adjacent wire.

  An object of the present invention is to provide a winding apparatus and a winding method for obtaining a cup-shaped coil in which the expansion of the outer diameter at both ends is suppressed.

  Another object of the present invention is to provide a winding apparatus and a winding method capable of shortening the time required for winding.

  Still another object of the present invention is to provide a winding apparatus and a winding method capable of bringing a wire rod wound around a winding jig into close contact with an adjacent wire rod.

  In the present invention, a winding jig which has a cylindrical shape and rotates around a central axis to wind a wire around and a winding jig spaced apart on both sides in the axial direction are arranged in the same direction as the winding jig. It is an improvement of a winding apparatus provided with a pair of rotating guide pieces and a wire supply means for supplying a wire around the winding jig so as to be a triangular wave with the guide pieces at the top.

  The characteristic point is that the wire feeding means feeds a wire provided around a rotating body rotating around an orthogonal axis orthogonal to the central axis of the winding jig or a parallel axis parallel to the orthogonal axis, and a wire And forward and reverse rotation means for rotating the rotating body forward and reverse, and the forward and reverse rotation means rotates the rotating body forward and reverse each time the pair of guide pieces make one rotation, thereby making the orthogonal axis or parallel axis As a center, it is configured to swing the nozzle once.

  In another embodiment of the present invention, the winding jig and a pair of guide pieces spaced apart on both sides in the axial direction of the winding jig are rotated in the same direction, and the wire drawn from the nozzle is a pair of guide pieces This is an improvement of the winding method of winding around the winding jig so as to be a triangular wave with the apex at the top.

  The characteristic point is that the nozzle is swung once around an orthogonal axis orthogonal to the central axis of the winding jig or a parallel axis parallel to the orthogonal axis every rotation of the pair of guide pieces. is there.

  When the winding apparatus includes a support jig for supporting the tip of the winding jig and a support rotating means for rotating the support together with the winding jig, the tip of the winding jig is the winding method. It is preferable to be supported by a support jig.

  In addition, a locking means is provided for locking the end of the wire wound around the winding jig to both the support rod provided with the winding jig at the tip and the support, and the winding means is provided with the winding jig It is also possible to lock the end of the wound wire.

  In the winding device and the winding method of the present invention, the wire rod is fed while swinging the nozzle, so the wire rod wound around one of the guide pieces is fed forward and backward in the rotational direction of the winding jig together with the nozzle. When the guide is later guided to the other guide side and the nozzle reaches the other guide side, the wire is folded back for the first time at one guide piece.

  In this manner, once the wire wound around the guide piece is guided forward or backward in the rotational direction of the winding jig and then guided to the other guide side and folded back the wire, the bulge of the folded back wire Head in the direction of rotation.

  For this reason, the nozzle is reciprocated in the axial direction of the winding jig, and in the guide piece, the wire rod is immediately folded outward in the radial direction of the winding jig as compared with the conventional case. It can reduce the outward swelling. Therefore, in the present invention, it is possible to obtain a coil in which the expansion of the outer diameter at both ends is suppressed.

  Further, in the present invention, in which the nozzle is swung, the moment of inertia around the nozzle can be reduced as compared with the conventional one in which the nozzle is reciprocated, so that the wiggle of the nozzle can be performed relatively quickly. Become. Therefore, in the present invention, it is possible to shorten the time required for the winding as compared with the conventional one.

  Furthermore, in the present invention, in which the wire jig is fed by rotating the winding jig and the guide piece and swinging the nozzle, the wire rod is wound around one of the guide pieces after it is wound around one of the guide pieces. It is guided in the rotational direction forward or backward, and when the nozzle reaches the other guide side, it comes into close contact with the previously wound wire rod. Therefore, in the present invention, so-called alignment winding is facilitated, in which the wire wound around the winding jig is brought into close contact with the adjacent wire.

The temporary fixing tool 92 in this embodiment includes a fluid pressure cylinder 93 provided below the winding jig 12 with the withdrawal rod 93a facing upward, and a coupling provided parallel to the nozzle 72 at the upper end of the withdrawal rod 93a. And a stop pin 94.

  And in this temporary fixing tool 92, the wire 11 drawn out from the nozzle 72 is wound on the locking pin 94 to temporarily fix the wire 11, and in this state, the projecting and retracting rod 93a of the fluid pressure cylinder 93 Is moved from the main body 93b or inserted into the main body 93b to move the locking pin 94 with the wire 11 tangled, the wire 11 extending from the locking pin 94 is torn off in the middle thereof Configured to be

  Next, a winding method of the present invention using such a winding device will be described.

  In the winding method of the present invention, first, as shown in FIG. 4, the wire 11 is passed from a wire supply source (not shown) to the guide cylinder 71d of the rotating body 71 and the wire 11 drawn out from the tip of the guide cylinder 71d is a nozzle Pass to 72. The wire 11 drawn out from the nozzle 72 in this manner is tangled with the locking pin 94 of the temporary fixing member 92 shown in FIG.

  Next, the guide pieces 61, which separate and approach the pair of single rotation means 62 and 62 respectively by the actuators 22 and 42 in which the movable bases 17 and 37 are provided on the followers 22c and 42c, respectively. , 61 in the axial direction of the winding jig 12 to be equal to the length L (FIG. 12) of the cup-shaped coil 9 to be obtained.

  Then, the winding jig 12 and the support 32 are made to approach each other by separate actuators 21 and 41 in the jig rotation means 13 and the support rotation means 33 respectively, and the tip of the support 32 is brought into contact with the tip of the winding jig 12 Get in touch.

  Next, the support rod 14 or the support 32 in the jig rotation means 13 or the support rotation means 33 is rotated to make the binding pin 60 provided on any of them face the nozzle 72.

  In this embodiment, the wire 11 at the beginning of the winding is tied to the binding pin 60 provided on the support 32, and the wire 11 at the end of winding is tied to the binding pin 60 provided on the support rod 14. explain.

  Therefore, the binding pin 60 provided on the support 32 in the support rotation means 33 is made to face the nozzle 72, and the nozzle 72 is provided on the support 32 by the nozzle moving means 80 around the binding pin 60. The wire 11 drawn out from the nozzle 72 is wound around the winding pin 60 as the wire 11 at the beginning of winding.

  At this time, in this embodiment in which the binding pins 60 are provided in two rows in the axial direction of the support rod 14 or the support member 32, the binding pins 60 provided in two rows are separated from the winding jig 12 The wire 11 is wound on the winding pin 60 on the other side.

  Then, after that, the retracting rod 93a of the fluid pressure cylinder 93 in the temporary fixing tool 92 is inserted into the main body 93b to move the locking pin 94 with the wire 11 tangled, thereby from the locking pin 94 The extending wire 11 is cut in the vicinity of the binding pin 60.

  Next, although it becomes a winding, first, while rotating the pair of guide pieces 61, 61 by the single rotation means 62, moving the rotating body 71 provided with the nozzle 72 together with the moving plate 70b, the start position shown in FIG. Make it

  In the process of moving the moving plate 70b to the start position, the wire rod 11 fed from the nozzle 72 is guided around the winding jig 12, and the rotation center of the rotating body 71 provided with the nozzle 72 is a pair of guide pieces 61, It is made to coincide with an orthogonal axis D which is middle of 61 and is orthogonal to the rotation center of the winding jig 12 or to be parallel with a parallel axis parallel to the orthogonal axis D.

  Then, the rotary body 71 is rotated by the nozzle servomotor 74, the nozzle 72 provided on the rotary body 71 is swung to the axial end of the winding jig 12, and the nozzle 72 is mounted on the support rod 14 side. The guide piece 61 is located outside.

  Then, the pair of guide pieces 61 and 61 are respectively rotated about the central axis C of the winding jig 12 so that the guide pieces 61 on the support rod 14 face the nozzle 72 and the guide pieces 61 on the support 32 are Keep away from the nozzle 72. At the same time, the support 32 on which the binding pin 60 is provided is rotated so that the binding pin 60 in which the wire 11 is bound is at a position away from the nozzle 72.

  Thus, as shown in FIG. 6, the wire 11 extending from the binding pin 60 to which the wire 11 is twisted to the nozzle 72 is from the guide piece 61 on the support 32 side to the guide piece 61 on the support rod 14 side. It is wound around the winding jig 12 for a half turn diagonally so as to reach to the end. A position as shown in FIG. 6 is a start position.

  While simultaneously rotating the winding jig 12 and the pair of guide pieces 61 and 61 about the central axis C of the winding jig 12 from the start position shown in FIG. The nozzle 72 is rocked by the forward and reverse rotation means 73. The swinging of the nozzle 72 is performed by the servomotor 74 for the nozzle, and the speed at which the nozzle 72 swings once when the pair of guide pieces 61, 61 make one rotation with the central axis C of the winding jig 12 as the rotation center. It is assumed.

  For this reason, as shown in FIG. 7, when the pair of guide pieces 61, 61 and the winding jig 12 rotate 90 degrees from the start position, the swinging nozzle 72 moves to a half of the coil length, and the wire 11 is wound around the winding jig 12 a quarter turn.

  When the pair of guide pieces 61, 61 and the winding jig 12 are further rotated 90 degrees from the start position and they are rotated 180 degrees from the start position, the left and right positions and the upper and lower positions of the pair of guide pieces 61, 61 as shown in FIG. Instead, the swinging nozzle 72 moves to the folding position, and the wire 11 is wound around the winding jig 12 by half.

  Further, when the winding jig 12 and the pair of guide pieces 61, 61 continue to rotate in the same direction, the nozzle 72 starts swinging in the opposite direction, and the wire 11 is caught on the outside of the other guide piece 61 and folded back. . Then, as shown in FIG. 9, when the pair of guide pieces 61, 61 and the winding jig 12 rotate 270 degrees from the start position, the wire 11 is wound around the winding jig 12 three quarters of a turn.

  Further, when the winding jig 12 and the pair of guide pieces 61, 61 rotate 360 degrees from the start position, they return to the start position shown in FIG. 6 and to the turning point of the swinging nozzle 72. Then, the wire 11 returned to the start position for the second time is folded back at the guide piece 61, and the same operation as described above is repeated thereafter.

  As described above, when the winding operation is repeated, the wire 11 supplied obliquely around the winding jig 12 is sequentially folded back by the pair of guide pieces 61 and 61, and the guide pieces around the winding jig 12 61 and 61 will be wound in a triangular wave shape with the apex.

  However, if the rotation speed and the rotation speed of the winding jig 12 and the pair of guide pieces 61, 61 are completely matched, the second wire 11 is overlapped on the first wire 11 and wound up at the second folding. Problems occur. For this reason, after the first winding of the wire 11, it is necessary to shift the second wire 11 in the circumferential direction of the winding jig 12.

  In this embodiment, the tip end of the guide piece 61 is directed rearward in the rotational direction of the winding jig 12 to contact the outer periphery of the winding jig 12. Therefore, after the first winding of the wire rod 11, the second time When the wire 11 comes, the rotation of the winding jig 12 is delayed with respect to the rotation of the pair of guide pieces 61, 61 by the thickness of the wire 11.

  That is, the controller (not shown) retards the winding jig 12 by the wire diameter of the winding wire 11 each time the pair of guide pieces 61 makes one rotation, and the wire 11 overlaps the winding jig 12. The rotation speed and the rotation speed of the winding jig 12 are controlled so as to be slightly smaller with respect to the rotation of the pair of guide pieces 61, 61 so as not to be wound up. The degree of retardation is set in accordance with the thickness of the wire 11 by a controller (not shown).

  Thus, every time the winding jig 12 makes one rotation, the rotation angle of the winding jig 12 is further retarded with respect to the pair of guide pieces 61, 61 by an angle corresponding to the thickness of the wire rod 11, The winding operation of rotating the winding jig 12 and the pair of guide pieces 61 is continued.

  Then, as shown in FIG. 10, the wire 11 is newly wound adjacent to the previously wound wire 11 and the winding operation is continued. The wire 11 supplied obliquely around the jig 12 is sequentially folded back by the pair of guide pieces 61, 61, and the triangular wire 11 adjacent to each other with the guide pieces 61, 61 as the apex around the winding jig 12 The coil 9a which consists of a set of is formed.

  Here, the wire rod 11 sequentially folded back by the pair of guide pieces 61, 61 is sequentially arranged to the rear in the rotational direction of the winding jig 12 together with the winding jig 12 that delays the rotation of the pair of guide pieces 61, 61. It moves and comes out of the tip edge of a pair of guide pieces 61,61.

  Thus, in the winding device 10, the wire 11 is wound in a triangular wave shape around the winding jig 12. In the winding device 10 of the present invention, as shown in FIG. Since the wire 11 is drawn out while being rocked, the wire 11 wound around the guide pieces 61, 61 is drawn out to the rear in the rotational direction of the winding jig 12 indicated by the solid arrow, and the other guide pieces 61, 61 side When the nozzle 72 reaches the other guide pieces 61, 61 side, the wire 11 is folded back for the first time.

  That is, as shown in FIG. 11A, when there is a nozzle 72 on the outside of one of the guide pieces 61, the wire 11 drawn from the nozzle 71 is adjacent to the wire 11 wound earlier. . When the nozzle 72 is swung while rotating the winding jig 12 and the pair of guide pieces 61, 61 from that state, as shown in FIG. 11 (b), the wire 11 cut out from the nozzle 72 is wound first. It is guided to the rear in the rotational direction of the winding jig 12 beyond the wound wire 11.

  Then, as shown in FIG. 11 (c), when the nozzle 72 reaches the other guide piece 61 side, at that stage, it returns to the front of the wire 11 wound previously and the wire wound ahead thereof It reaches around the winding jig 12 while being adjacent to 11. Thus, at the stage when the nozzle 72 reaches the other guide piece 61 side, the wire 11 is folded back at one guide piece 61 and becomes a triangular wave wire 11 with the one guide piece 61 as an apex.

  As described above, when the wire 11 wound around one of the guide pieces 61 is once guided to the rear in the rotational direction of the winding jig 12 and then guided to the other guide piece 61 and the wire 11 is folded back, the wire 11 is folded back. Bulges in the rotational direction of the winding jig 12. For this reason, the nozzle can be reciprocated, and the outward swelling of the wire jig 11 in the radial direction of the wire rod 11 to be folded back can be reduced as compared with the conventional case where the wire rod is immediately folded back at the guide piece. Therefore, in the present invention, it is possible to obtain a coil in which the expansion of the outer diameter at both ends is suppressed.

  In addition, when the winding jig 12 is retarded by the thickness of the wire 11 every one rotation of the guide pieces 61, 61, a new triangular wave-like wire is adjacent to the triangular wave 11 formed previously. 11 are wound around a winding jig 12. Here, as shown in FIG. 11, in the present invention, in which the wire rod 11 is fed out while swinging the nozzle 72, the wire rod 11 which is newly drawn from the nozzle 72 is first wound around the guide pieces 61, 61. The wire 72 is guided to the rear in the rotational direction of the winding jig 12 beyond the wound wire rod 11 and then the nozzle 72 reaches the side of the other guide pieces 61, 61 before the wire rod 11 is wound earlier. It returns to the circumference of the winding jig 12 while being adjacent to the wire 11 wound in the end.

  Therefore, no gap is generated between the triangular wave-shaped wire 11 to be formed later and the triangular wave-shaped wire 11 previously formed. Therefore, according to the present invention, so-called aligned winding is facilitated, in which the wire 11 wound around the winding jig 12 is brought into close contact with the adjacent wire 11.

  Furthermore, the rotary body 71 provided with the nozzle 72 can reduce its moment of inertia. Therefore, it is possible to swing the nozzle 72 of the present invention more quickly as compared with the conventional apparatus in which the mass of members around the nozzle increases and the nozzle linearly reciprocates in the axial direction of the winding jig. Become. In the present invention, therefore, the time for winding can be shortened.

  Then, when winding while bringing the triangular wave wires 11 adjacent to each other into close contact with each other around the winding jig 12, the hot air generator 91 (FIG. 1) mounted on the base 10 a Hot air is blown toward the winding jig 12 from the hot air outlet 91a to be faced, the wire rods 11 wound adjacent to the winding jig 12 are adhered to each other, and thereafter the mold is prevented from being broken.

  After the above-described winding operation is repeated to obtain a single coil 9a, as shown in FIG. 12, the wire 11 at the end of the winding will be entwined on the binding pin 60 provided on the support rod 14. .

  In winding the wire 11 at the winding end, the nozzle moving means 80 causes the nozzle 72 to circulate around the winding pin 60 provided on the support rod 14, and the wire 11 drawn out from the nozzle 72 is wound at the winding end The wire 11 is wound on the winding pin 60.

  At this time, since the binding rods 60 are provided in two rows in the support rod 14 in the axial direction, the wire is used for the binding pins 60 in the vicinity of the winding jig 12 of the binding pins 60 provided in two rows. After the wire 11 is wound, the wire 11 is wound on the winding pin 60 on the side away from the winding jig 12.

  Thereafter, the nozzle moving means 80 circulates the nozzle 72 around the locking pin 94 in the temporary fixture 92 shown in FIG. 2, and the wire 11 drawn from the nozzle 72 is wound on the locking pin 94 in the temporary fixture 92. You Then, after that, the retracting rod 93a of the fluid pressure cylinder 93 in the temporary fixing tool 92 is inserted into the main body 93b to move the locking pin 94 with the wire 11 tangled, thereby from the locking pin 94 The extending wire 11 is cut in the vicinity of the binding pin 60.

  Thereafter, the pair of guide pieces 61, 61 are rotated forward in the rotational direction of the winding jig 12, and the pair of guide pieces 61, 61 are extracted from the wire 11 wound around the winding jig 12, and the pair of guides The wire 11 wound so as to form a triangular wave with the pieces 61 and 61 at the top is left around the winding jig 12 to complete the production of the single coil 9a.

  As shown in FIG. 12, in this embodiment for producing a cup-shaped coil 9 consisting of three coils 9a, the above-mentioned winding operation performed to obtain a single coil 9a is repeated a total of three times, and the beginning of winding A cup-shaped coil 9 is obtained in which the wire 11 and the wire 11 at the end of the winding consist of three coils 9a drawn from both sides in the axial direction.

  Here, in the case where the single coil 9a is obtained first, at the start of the winding for obtaining the next single coil 9a, a pair of the coils extracted from the single coil 9a obtained previously is obtained. The guide pieces 61, 61 are again rotated to the start position shown in FIG.

  However, when rotating the pair of guide pieces 61, 61 in a state where a single coil 9a is obtained first, as shown in FIG. It is preferable to separate from the outer periphery of the winding jig 12 and to carry out in that state.

  Thus, by rotating the guide pieces 61, 61 in a state in which the tip is separated from the outer periphery of the cylindrical winding jig 12, the guide pieces 61, 61 are rotated to the single coil 9a obtained earlier. It is possible to avoid contact and rubbing.

  Then, the above-mentioned winding operation is repeated a total of three times, and after the cup-shaped coil 9 is obtained, the wire 11 at the beginning of winding and the wire 11 at the end of winding wound around the winding pin 60 are unwound and the winding jig 12 And the support tool 32 are respectively separated, and the cup-shaped coil 9 consisting of the wire rod 11 wound around the winding jig 12 is removed from the space between them to complete a series of winding operations.

  In the embodiment described above, the tip end of the guide piece 61 is directed rearward in the rotational direction of the winding jig 12 to contact the outer periphery of the winding jig 12, and each time the pair of guide pieces 61, 61 make one rotation, The case where the winding jig 12 is retarded by the wire diameter of the wire 11 to be wound up has been described. However, the tip end of the guide piece 61 is directed forward in the rotational direction of the winding jig 12 to contact the outer periphery of the winding jig 12, and the wire diameter of the wire 11 wound up every time the pair of guide pieces 61, 61 make one rotation. The winding jig 12 may be advanced by an amount.

  In the embodiment described above, the case where the locking means for locking the end of the wire 11 is the binding pin 60 has been described, but as long as the locking means can lock the end of the wire 11, Not limited to the binding pin 60, other types may be used.

  Furthermore, in the embodiment described above, in FIGS. 6 to 10, the case where the nozzle 72 is swung by the rotating body 71 rotating about the orthogonal axis D orthogonal to the central axis C of the winding jig 12 has been described. However, although not shown, the rotary body 71 may be rotated about a parallel axis parallel to the orthogonal axis D, and the nozzle 72 may be swung about the parallel axis.
