Description

  The present invention relates to a para-winding method and a para-winding device in which a plurality of conductive wires are arranged in parallel and wound around a winding frame to form a coil, and the coil is dropped into a coil receiving jig.

  In recent years, when developing motors such as electric vehicles, a large driving force can be obtained by enlarging the cross-sectional area of the wire and flowing a large current so that a large driving force can be obtained by a low-voltage power source that can be mounted on the vehicle. There is a demand for a motor that can achieve the above. However, when the diameter of the electric wire is increased, the winding operation and the coil insertion operation into the stator core become difficult, and the space factor (space occupancy) of the electric wire in the slot of the stator core is reduced. It was.

  Therefore, by winding a plurality of electric wires in parallel (para-winding) to form a coil, the cross-sectional area of the electric wire is substantially increased without hindering the winding operation and the coil insertion operation. A winding device and method are proposed. In such a para-winding, a conventional winding device using a rotary nozzle called a flyer cannot be used as it is. In other words, when a flyer that rotates a nozzle for feeding an electric wire around a reel and winds the electric wire around the reel is used, a plurality of electric wires are twisted like a rope, and the obtained coil is used in a later step. This is because it becomes difficult to insert into the stator core slot by the coil insertion device.

  For this reason, for example, in Patent Document 1 below, winding of a predetermined number of poles connected to each other is repeated by repeating winding formation by winding a wire around the winding frame and removal of the winding from the winding frame. In a winding manufacturing system for forming a wire, a winding forming means for forming a winding by winding an element wire around a rotating winding frame, and a winding that has been completely wound and removed from the winding frame, Winding holding means for holding in a predetermined holding position corresponding to the winding, and by moving the winding holding means in accordance with the rotation of the winding frame, the winding held by the winding holding means and other poles And a relative position maintaining means that suppresses the deviation of the relative positional relationship with the winding frame in which the winding is being formed is disclosed.

Further, in Patent Document 2 below, in a winding machine in which a plurality of wires arranged in a strip shape supplied from a flyer through a tension nozzle are wound around a winding frame, the circumference thereof is coaxial with the winding frame. A dummy drum with approximately the same circumferential length is provided to be rotatable, and a dummy flyer is provided to wind the wire around the dummy drum integrally with the flyer. The tension nozzle is moved upward and the dummy drum is moved downward in synchronization with the rotation of the flyer and dummy flyer Winding machine that prevents kinking and facilitates insertion into the coil insertion jig and improves the space factor by simultaneously winding the wire around the winding frame and the dummy drum while moving to the same speed. Is disclosed.

  However, in the technique of the above-mentioned patent document 1, the connection state between the coil that has already been wound and held by the winding holding means (coil receiving jig) and the coil that is newly wound around the winding frame is maintained. Therefore, since the winding frame and the winding holding means must be rotated in synchronization, it is difficult to speed up the winding cycle.

  Moreover, in the technique of the above-mentioned Patent Document 2, a dummy drum must be disposed above the winding frame, and winding must be performed simultaneously on the winding frame and the dummy drum by two flyers. There is a tendency that the size is remarkably increased, the structure is complicated, and the cost of the apparatus is increased.

  Accordingly, it is an object of the present invention to provide a para-winding method and a para-winding apparatus that can accelerate the winding cycle with a relatively simple structure.

In order to achieve the above object, one of the present invention is a para-winding method in which a plurality of conductive wires are arranged in parallel and wound around a winding frame to form a coil, and the coil is dropped into a coil receiving jig.

Furthermore, a pair of end face plates 44 and 45 and a plurality of separators 46 disposed therebetween are penetrated in the rotation axis direction and extended in the radial direction, and the inner peripheral side end portion of the annular groove 48 is formed. A through hole 50 reaching the inner periphery is formed.

  As shown in FIGS. 7 and 8, a guide groove 52 that crosses the rotating plate 37 in the diametrical direction is formed on the upper surface of the rotating plate 37. A lever 53 is slidably inserted into the guide groove 52, and a bar-shaped clamp 54 extending downward is integrally provided at one end of the lever 53 protruding from the guide groove 52. In addition, a cam follower 55 is attached to one place on the upper surface of the lever 53. Further, a cam plate 56 is rotatably mounted on the upper portion of the guide groove 52 of the rotating plate 37. A cam groove 57 is formed on the lower surface of the cam plate 56, and the cam follower 55 of the lever 53 is inserted into the cam groove 57.

  One end of the cam groove 57 is located on the inner peripheral side of the cam plate 56, and the other end is located on the outer peripheral side of the cam plate 56. The upper surface of the cam plate 56 is covered with a cover 37a that is integral with the rotary plate 37. An arc-shaped slit 66 is formed in the cover 37a, and the cam fixed to the cam plate 56 through the slit 66. A plate rotation protrusion 58 is extended.

  On the other hand, below the support plate 32, an auxiliary plate 64 is disposed substantially parallel to the support plate 32 via a spacer 64a. The auxiliary plate 64 extends in the same direction as the lever 53 inserted in the guide groove 52 of the rotating plate 37, and has a pair of end portions extending in a direction facing the rotating plate 37. A clamp release air cylinder 59 is attached to one end of the auxiliary plate 64, and the operating rod of the clamp release air cylinder 59 forms a pusher 61.

  The pusher 61 is disposed at a position where the pusher 61 can come into contact with the cam plate rotation protrusion 58 at a position where the rotation plate 37 is moved upward by the air cylinder 34. That is, when the pusher 61 is pushed out by the clamp releasing air cylinder 59 at that position, the pusher 61 hits the cam plate rotation protrusion 58 and moves the cam plate rotation protrusion 58 along the slit 66. Then, the cam plate 56 to which the cam plate rotation protrusion 58 is connected rotates, the lever 53 slides through the cam follower 55 inserted into the cam groove 57, and the clamp 54 moves to the outer peripheral side of the bobbin 40.

  A clamp fixing air cylinder 62 is attached to the other end of the auxiliary plate 64 via a holding plate 65. The operating rod of the clamp fixing air cylinder 62 constitutes a pusher 63. The pusher 63 is in a position where it can come into contact with the cam plate rotation protrusion 58 when the rotary plate 37 comes into contact with the upper surface of the bobbin 40 by the operation of the air cylinder 34. That is, when the pusher 63 is pushed out by the operation of the clamp fixing air cylinder 62 at that position, the cam plate rotation protrusion 58 is moved along the slit 66 in the opposite direction. As a result, the cam plate 56 connected with the cam plate rotation protrusion 58 rotates in the opposite direction, and the lever 53 moves in the opposite direction through the cam follower 55 inserted in the cam groove 57. By sliding, the clamp 54 moves to the inner peripheral side of the bobbin 40.

  The clamp 54 is inserted into the through hole 50 of the bobbin 40 when the rotating plate 37 is lowered by the operation of the air cylinder 34 and comes into contact with the upper surface of the bobbin 40. Therefore, as described above in this state, by moving the clamp 54 to the inner peripheral side of the bobbin 40, the respective lead wires W inserted into the plurality of annular grooves 48 defined by the plurality of separators 46 are moved to the clamp 54. By this, it is pressed against the inner peripheral surface of the annular groove 48 to be clamped.

  Thus, the clamp 54 can clamp and fix the start ends of the plurality of conductive wires W inserted into the annular groove 48 of the bobbin 40 at a time. The clamp 54 rotates together with the rotating plate 37. During this rotating operation, the pusher 63 of the clamp fixing air cylinder 62 moves backward and waits at a position where it does not interfere with the cam plate rotating projection 58. .

The cutter 60 is attached to a holder 69 attached via an air cylinder 68 to the lower surface of the upper table 14 attached to the upper end of the standing wall 13. The cutter 60 is opened and closed by a built-in air cylinder, and is moved up and down by the air cylinder 68.

  A winding device main body 70 is disposed above the support 24 and the coil receiving jig 120 that are disposed on the circumference of the bobbin moving device 20 away from the conductor supply device 15. The winding device main body 70 includes a pair of guide posts 71 erected on the upper table 14 and a support plate 72 that continuously connects the upper ends of the guide posts 71. An elevating plate 73 is attached to the pair of guide posts 71 so as to be movable up and down. At the center of the lower surface of the elevating plate 73, the upper end of the support cylinder 74 is fixed.

  Referring also to FIG. 9, the support cylinder 74 passes through the upper table 14, and a winding frame 76 is attached to the lower end of the support cylinder 74 via a winding frame holder 75. The winding frame 76 includes a front winding frame 77 and a rear winding frame 78. Further, on the upper surface of the central portion of the elevating plate 73, a dust-carrying plate air cylinder 79 is installed, and its operating rod extends downward through the elevating plate 73, and a rod 81 is connected thereto.

Become. In addition, as shown in FIG. 30, in the state where the dropping plate 30 is raised, the cam 87 attached to the rod 81 hits the connecting portion of the links 85 and 86 so that the links 85 and 86 are extended. The tilting plate 84 is horizontal against the urging force of the spring 88, and the rear winding frame 78 is supported substantially parallel to the front winding frame 77.

  Therefore, when the coil 82 wound down to drop the coil wound around the winding frame 76 into the coil receiving jig 120, the cam 87 is detached from the links 85 and 86, and the links 85 and 86 are bent and tilted. Since the plate 84 tilts and the rear reel 78 falls inward, the coil can be easily dropped.

  A rotating cylinder 80 is rotatably mounted on the outer periphery of a portion that penetrates the upper table 14 of the support cylinder 74 via a bearing 89 a mounted on the upper table 14. A driven pulley 89 is integrally formed at the upper end of the rotating cylinder 80. The driven pulley 89 is connected to a drive pulley 92 of a flyer rotating motor 91 (see FIG. 1) installed on the upper table 14 via a timing belt 93.

  On the other hand, a flyer arm 97 is attached to the other end of the rotating plate 94 facing in the circumferential direction so as to protrude downward. The flyer arm 97 has a cylindrical shape, and an upper end of the flyer arm 97 penetrates the rotating plate 94, and a flange portion 97 a contacting the lower surface of the rotating plate 94 is fixed to the rotating plate 94 by bolts 141.

  Referring to FIGS. 12 and 13 together, a slide cylinder 98 is inserted into the flyer arm 97 through a bearing 140 disposed on the inner periphery of the upper and lower ends thereof so as to be slidable in the vertical direction and rotatable. A plurality of flaps 99 are attached to the lower end portion of the slide cylinder 98 so as to be openable and closable. The upper end portion of the slide cylinder 98 is inserted from the upper end of the flyer arm 97, and a planetary gear 142 is mounted on the outer periphery of the upper end. In the middle of the inner periphery of the slide cylinder 98, a reduced diameter step portion 98a is formed.

The bobbin detaching apparatus 100 has the following structure. That is, an opening 14a is formed in a portion of the upper table 14 located above the position where the above detaching operation is performed. An elevating cylinder 110 is attached to the periphery of the opening 14a with a working rod 111 facing downward via a bracket 14b. A block 112 is attached to the operating rod 111, and a cylindrical plug 113 is integrally formed at the lower end of the block 112. The plug 113 is inserted in conformity with the inner periphery 98b of the upper end portion of the slide cylinder 98.

A ball 107 is disposed between the push shaft 108 and the plug 113, and a hole through which the ball 107 can partially protrude is formed at a position corresponding to the ball 107 of the plug 113. Further, the push shaft 108 has an annular groove 109. When the annular groove 109 is disposed at the position of the ball 107, the ball 107 can be immersed in the inner periphery of the plug 113. On the other hand, when the push shaft 108 slides in the axial direction and the annular groove 109 deviates from the position of the ball 107, the ball 107 is pushed by the push shaft 108 and protrudes to the outer peripheral side of the plug 113. . The plug 113 can be moved up and down together with the demounting cylinder 101 by the lifting cylinder 110.

  Further, as shown in FIG. 9, a rotating cylinder 145 is disposed on the outer periphery of the rotating cylinder 80 mounted on the outer periphery of the portion passing through the upper table 14 of the supporting cylinder 74 via a bearing 144.

Therefore, when the drive gear 147 is rotated by the operation of the servo motor 146, the rotating cylinder 145 is rotated through the large diameter gear 145a, the idle gear 148 is rotated through the large diameter gear 145b, and further through the idle gear 148. The planetary gear 142 rotates. For this reason, the slide cylinder 98 integral with the planetary gear 142 rotates.

  Then, the flap 99 at the lower end of the slide cylinder 98 is inserted into the inner periphery of the bobbin 40 and is expanded in diameter by the wedge 103b so as to be pressed against the inner periphery of the bobbin 40 so as to fix and hold the bobbin 40. . Therefore, when the slide cylinder 98 rotates as described above, the bobbin 40 attached to the lower end of the slide cylinder 98 also rotates together therewith. The rotation direction and rotation speed of the bobbin 40 can be freely controlled by rotating the servo motor 146 at a pre-programmed direction and rotation speed. The slide cylinder 98 constitutes a rotation support means for the bobbin 40 in the present invention.

  In addition, 130 in FIG. 10 is a clamp of the conducting wire W, and this conducting wire clamp 130 can be moved in the XYZ directions by a driving mechanism (not shown).

  Referring to FIGS. 1 and 12 together, a turntable 123 is disposed on the table 12, and a coil receiving jig 120 is disposed on the turntable 123 via a cradle 121. The coil receiving jig 120 has a plurality of guide rods 122 arranged in an annular shape, and the coil wound around the winding frame 76 is dropped into a predetermined gap between the guide rods 122. It has become.

  On the turntable 123, a plurality of, in the case of this embodiment, two coil receiving jigs 120 are arranged facing each other in the circumferential direction, and one of the coil receiving jigs 120 is below the winding frame 76. The other coil receiving jig 120 is removed together with the wound coil and is replaced with another coil receiving jig 120 having no coil. The coil receiving jig 120 is rotated by a predetermined angle each time winding of one coil is finished by a driving mechanism (not shown), and a newly wound coil is arranged in a predetermined gap of the guide rod 122. It is designed to be positioned.

  Next, an embodiment of a para winding method according to the present invention using the para winding device 10 will be described.

  First, an operation for winding the conducting wire W around the bobbin 40 by the bobbin winding device 30 will be described.

  After the winding operation is finished, the empty bobbin 40 attached to the flyer arm 97 is removed, and the bobbin 40 wound with the conductive wire W by the bobbin winding device 30 by the rotation of the rotary table 23. The exchanged state is shown in FIGS. At this time, the conducting wire W is drawn from the wound bobbin 40 to form a path to the conducting wire supply device 15. Further, the empty bobbin 40 is disposed below the bobbin winding device 30, and the conducting wire W is inserted into the corresponding annular groove 48 partitioned by the separator 46 of the empty bobbin 40. The empty bobbin 40 is positioned so that the lead wire W passes through the portion of the through hole 50 by the rotation positioning roller 25a.

  Next, as shown in FIGS. 23 and 24, the conductive wire W is held by the conductive wire clamp 130 on the path of the conductive wire W. Further, as shown in FIGS. 25 and 26, the cutter 60 descends to a portion closer to the conductor supply device 15 than the conductor clamp 130, and the conductor W is cut. After the conductor W is cut in this way, as shown in FIGS. 27 and 28, the conductor W is pulled back by the pull-back cylinder 17 (see FIG. 2) of the conductor supply device 15, and the end of the cut conductor W is transparent. It is arranged at a position slightly passing through the hole 50.

  In this way, the air cylinder 34 shown in FIG. 7 operates and the rotating plate 37 descends with the ends of the plurality of conducting wires W inserted into the annular groove 48 of the bobbin 40. Then, the clamp 54 attached to the rotating plate 37 is inserted into the through hole 50, and the protrusion 38 of the rotating plate 37 shown in FIG. 4 is inserted into the hole 43 of the bobbin 40.

  Then, the clamp fixing air cylinder 62 shown in FIG. 7 is actuated to push out the pusher 63, the cam plate rotation protrusion 58 is pushed by the pusher 63, the cam plate 56 rotates, and the lever is provided via the cam groove 57 and the cam follower 55. 53 slides and the clamp 54 moves to the inner peripheral side of the through hole 50 as shown by the imaginary line in FIG. As a result, the ends of the conductive wires W inserted into the plurality of annular grooves 48 of the bobbin 40 are simultaneously clamped by the clamps 54.

  The pusher 63 returns to the original position after sliding the lever 53 so that it does not interfere with the rotation of the rotating plate 37. In this state, the motor 39 of the bobbin winding device 30 operates (see FIG. 3), the rotating plate 37 rotates through the driving pulley 41, the timing belt 42, and the driven pulley 36, and the bobbin 40 rotates with it. The plurality of conductive wires W are wound around the corresponding annular grooves 48 of the bobbin 40, respectively.

  Thus, when the winding operation around the bobbin 40 is completed, the motor 39 is stopped and the rotating plate 37 is stopped. Then, the rotary plate 37 is raised by the air cylinder 34 via the spline shaft 35, and the clamp 54 is extracted from the through hole 50 and separated from the bobbin 40.

  Since the conducting wire W is inserted and wound in the corresponding annular groove 48 partitioned by the separator 46, it does not cross each other, and is smoothly drawn when being drawn in the winding process described later. .

  While the operation of winding the conductive wire W around the bobbin 40 by the bobbin winding device 30 is performed, the other bobbin 40 is mounted on the flyer arm 97 of the winding device body 70 and the winding operation is performed. Yes. When the bobbin 40 used for the winding operation is emptied by the end of the winding operation, the bobbin 40 is transferred from the flyer arm 97 to the support unit 24, and the rotary table 23 rotates to wind the conductive wire W. To be exchanged.

  Next, an operation of removing the bobbin 40 that has been emptied after completing the winding operation and replacing it with the bobbin 40 wound as described above will be described.

  FIG. 14 shows a state where the bobbin 40 which is attached to the flyer arm 97 and the winding operation is finished and is emptied is mounted. At this time, the flyer arm 97 is located on the support portion 24.

  As shown in FIG. 15, in this state, the elevating cylinder 26 of the support portion 24 is operated, and the support plate 27 is raised and contacts the lower surface of the bobbin 40. On the other hand, the elevating cylinder 110 of the bobbin detaching apparatus 100 is operated, and the plug 113 is lowered and inserted into the inner periphery 98b of the upper end portion of the slide cylinder 98.

  As shown in FIG. 16, the demounting cylinder 101 is operated, the push shaft 108 is pushed downward, the head 103 a of the central shaft 103 is pressed, and the central shaft 103 is resisted against the urging force of the compression coil spring 143. Is lowered. As a result, the wedge 103b moves downward on the inner periphery of the flap 99 at the lower end of the slide shaft 98, and the pressing force against the flap 99 is released. Therefore, the flap 99 is reduced in diameter by the elastic ring 99a (see FIG. 13), and the bobbin 40 The engagement with the inner periphery is released. Further, when the push shaft 108 is lowered, the ball 107 (see FIG. 12) located in the annular groove 109 of the push shaft 108 is released from the annular groove 109 and pushed onto the outer periphery of the plug 113. The plug 113 and the slide cylinder 98 are integrated by the pressing force.

  As shown in FIG. 17, the elevating cylinder 110 operates to raise the plug 113 and raise the slide shaft 98 integrally therewith. As a result, the flap 99 at the lower end of the slide shaft 98 is extracted from the inner periphery of the bobbin 40. At the same time, the cylinder 28 of the support portion 24 is operated, and the support roller 29 is inserted into the inner periphery of the bobbin 40.

  As shown in FIG. 18, the rotary table 23 (see FIG. 1) rotates, and the wound bobbin 40 moves below the flyer arm 97. The empty bobbin 40 removed from the flyer arm 97 in the above process moves below the bobbin winding device 30.

  As shown in FIG. 19, the cylinder 28 of the support portion 24 is operated to lower the support roller 29, and is extracted from the inner periphery of the bobbin 40, and the elevating cylinder 110 of the bobbin detaching apparatus 100 is operated to At the same time, the slide cylinder 98 is lowered, and the flap 99 at the lower end of the slide cylinder 98 is inserted into the inner periphery of the bobbin 40.

  As shown in FIG. 20, the detaching cylinder 101 of the bobbin detaching apparatus 100 is operated, the push shaft 108 is raised, and the ball 107 is positioned in the annular groove 109. As a result, the ball 107 is drawn into the inner periphery of the plug 113 and the engagement between the plug 113 and the slide cylinder 98 is released. At the same time, the central shaft 103 that has been pushed by the push shaft 108 is lifted by the urging force of the compression coil spring 143, the wedge 103b is lifted in the flap 99, and the inner periphery of the flap 99 is pressed in the outer diameter direction, so that the bobbin 40 is engaged with the inner periphery.

  As shown in FIG. 21, the elevating cylinder 110 is actuated to raise the plug 113, and the plug 113 is extracted from the inner periphery 98 b of the upper end portion of the slide cylinder 98. At the same time, the elevating cylinder 26 and the cylinder 28 of the support portion 24 are operated, and the support plate 27 and the support roller 29 are lowered.

  In this way, the bobbin 40 that has been emptied after the winding operation can be removed from the lower end of the flyer arm 97 and replaced with the wound bobbin 40.

  Next, an operation of rotating the flyer 90 and winding a plurality of parallel wires W around the winding frame 76 will be described.

  The bobbin 40 attached to the flyer arm 97 is rotated by the flyer 90 and the winding operation with respect to the winding frame 76 is started. The flyer 90 is rotated through the driving pulley 92, the timing belt 93, the driven pulley 89 (see FIG. 9), and the rotating plate 94 by the operation of the flyer rotating motor 91 in FIG.

  By the way, in order for the lead wire W of the bobbin 40 to be drawn out and wound around the reel 76 by the rotation of the flyer 90, the bobbin 40 itself must also rotate with respect to the flyer 90. For this reason, in the present invention, the bobbin 40 itself is rotated by the servo motor 146 so that the plurality of conductive wires W are fed out from the bobbin 40 in accordance with the length wound around the winding frame 76. That is, when the drive gear 147 is rotated by the operation of the servo motor 146, the rotating cylinder 145 rotates through the large diameter gear 145a, the idle gear 148 rotates through the large diameter gear 145b, and further through the idle gear 148. As a result, the planetary gear 142 rotates. For this reason, the slide cylinder 98 integral with the planetary gear 142 rotates, and the bobbin 40 attached to the lower end of the slide cylinder 98 rotates.

  In this case, the rotation direction and rotation speed of the bobbin 40 need to be adjusted by the rotation direction of the flyer 97, the winding radius of the conductive wire W remaining on the bobbin 40, and the like.

  For example, as shown in FIG. 29 (a), when the flyer 90 rotates in the direction of arrow A, the bobbin 40 must rotate in the direction of arrow B in order to feed the conductor W in the direction of the conductor clamp 130. . In this case, if the large-diameter gears 145a and 145b are fixed, the bobbin 40 rotates too much in the arrow B direction via the idle gear 148 and the planetary gear 142. For this reason, the servomotor 146 rotates the drive gear 147 in the direction of arrow C and rotates the large-diameter gears 145a and 145b in the direction of arrow D, resulting in delaying the rotation of the bobbin 40 in the direction of arrow B. .

  Further, as shown in FIG. 5B, when the flyer 90 rotates in the direction of arrow E, the bobbin 40 must also rotate in the direction of arrow B in order to feed the conductor W in the direction of the conductor clamp 130. Don't be. In this case, if the large-diameter gears 145a and 145b are fixed, the bobbin 40 tends to rotate in the direction opposite to the arrow B via the idle gear 148 and the planetary gear 142. Therefore, the servo motor 146 rotates the drive gear 147 at high speed in the direction of arrow F, rotates the large-diameter gears 145a and 145b in the direction of arrow G, and rotates the bobbin 40 in the direction of arrow B.

  Further, as the conducting wire W is fed out from the bobbin 40 and the winding radius of the conducting wire W on the bobbin 40 becomes smaller, the length of the conducting wire W fed out by one rotation of the bobbin 40 becomes shorter. It must be rotated at high speed.

  The servo motor 146 can freely set the rotation direction and rotation speed of the bobbin 40 as described above by a program. Therefore, the bobbin 40 can be adjusted in accordance with the length of the plurality of conductors W wound around the reel 76. The wire W can be accurately fed out from the wire 40, the wire W can be prevented from being slackened, and the wire W can be aligned and wound around the winding frame 76, and the wire W can be pulled strongly to break the device. The occurrence of accidents can also be prevented. Further, by controlling the torque of the servo motor 146, an appropriate tension can be applied to the conducting wire.

  Further, along with this winding operation, the lifting plate 73 is gradually lowered by the operation of the lifting motor 73a of FIG. 1, and the winding frame 76 is gradually moved through the support cylinder 74 connected to the lifting plate 73. Descend. As the reel 76 is lowered, the guide rod 122 (see FIG. 11) of the coil receiving jig 120 disposed below the reel 76 is inserted into the front reel 77, and the coil wound around the reel 76 is guided. The rod 122 is inserted into a predetermined gap. FIG. 32 shows a state in which the flyer 90 has been rotated by a half turn and the conducting wire W drawn from the bobbin 40 has started to be wound around the lower end of the reel 76.

  As shown in FIG. 31, each time the flyer 90 rotates once and the conductive wire W is wound around the winding frame 76, the winding frame 76 is lowered by the width of the conductive wire W, and the conductive wire W moves upward from below the winding frame 76. It is wound in a spiral while being arranged in a row toward.

  Thus, when the winding for one pole is completed, the rotation of the flyer 90 is stopped, and the operation of the air cylinder 79 for the wiping plate lowers the wiping plate 82 so that the coil wound on the reel 76 is removed. , All fall into a predetermined gap of the guide rod 122 of the coil receiving jig 120. At this time, as described above, the cam 87 of the rod 81 is disengaged from the links 85 and 86, the links 85 and 86 are bent, the tilting plate 84 is tilted, and the rear reel 78 falls down, so that the coil W is dropped. Can be made easier.

  As the winding frame 76 is lowered, the guide rod 122 is inserted into the front winding frame 77 as described above. Therefore, dropping of the wound coil into the coil receiving jig 120 is parallel to the winding operation. When the winding operation is completed, the scraping plate 82 descends immediately after that and all the coils are dropped into the coil receiving jig 120. Therefore, the movement of the wound coil to the coil receiving jig 120 is It ends almost simultaneously with the end of the winding operation.

  Thus, when the one-pole winding operation is completed, the coil receiving jig 120 is rotated by a predetermined angle by a drive mechanism (not shown), and the other gap of the guide rod 122 is disposed at a position aligned with the winding frame 76. The coil winding is started. The conductor clamp 130 re-clamps the portion of the conductor W drawn from the bobbin 40 at the end of winding of the first pole coil, and holds the starting end of the conductor W during the second pole winding operation. Play a role. Such winding operation is repeated, and the coils of the respective poles are dropped into the predetermined gaps of the guide rod 122 of the coil receiving jig 120 as shown in FIG.

  When the winding operation is completed, the turntable 123 rotates, and a new coil receiving jig 120 that does not hold the coil is disposed below the winding frame 76. And the coil of the some pole hold | maintained at the coil receiving jig | tool 120 is inserted in the slot of a stator core by a well-known coil insertion apparatus.

  Thus, when the conducting wire W wound around one bobbin 40 is consumed by the aforementioned winding operation, the emptied bobbin 40 is returned to the support portion 24 by the aforementioned mechanism, and the conducting wire W is interposed during the winding operation. The new bobbin 40 wound around is placed below the flyer arm 97 by the bobbin moving device 20, and a new winding operation is started.

  Thus, according to the present invention, a plurality of conducting wires W are once wound around the bobbin 40, the bobbin 40 is mounted on the flyer arm 97, and the flyer 90 is rotated. Since the wire is wound around the winding frame 76 while being pulled out, the plurality of conductive wires W can be wound around the winding frame 76 without being twisted. Further, by controlling the servo motor 146, the plurality of conductors W can be accurately fed out from the bobbin 40 while applying appropriate tension according to the length wound around the winding frame 76, It is possible to prevent the lead wire W from slacking and to wind the lead wire W in alignment with the winding frame 76, and to prevent the occurrence of an accident such as the lead wire W being strongly pulled and damaging the apparatus. Further, by rotating the flyer 90, the coil W wound around the winding frame 76 can be sequentially dropped into the coil receiving jig 120 during the winding operation, and the coil moves from the winding frame 76 to the coil receiving jig 120. Can be performed simultaneously, so the winding cycle can be accelerated.

  According to the present invention, it is possible to provide a para-winding method and a para-winding device in which a plurality of conductive wires are arranged in parallel and wound around a winding frame to form a coil, and this coil is dropped into a coil receiving jig. For example, it can be used as a coil winding method and a winding device suitable for a motor of an electric vehicle or the like.
