Description

  The present invention relates to a flyer-type winding device for winding a multi-pole armature such as a motor. More specifically, the present invention relates to a flyer-type winding apparatus including a guide member that guides a wire to a slot of a multipole armature.

  Conventionally, in order to wind a wire for forming a coil around a magnetic pole of a multipole armature, a flyer-type winding provided with a flyer that winds the wire while rotating around the magnetic pole and winds the wire around the magnetic pole. Wire systems are widely used. In this flyer-type winding device, a guide member is provided for guiding a wire fed from a rotating flyer with respect to a magnetic pole that is a core of a multipole armature whose position is fixed. Since this guide member guides the wire against the fixed magnetic pole, it needs to be held stationary with respect to the armature. As a structure for holding the guide member in a stationary state in this way, the applicant has proposed a winding device (FIG. 12) using a main spindle provided with a flyer and a secondary spindle that rotates in synchronization with the main spindle. (For example, see Patent Document 1).

  A winding apparatus 200 shown in FIG. 12 includes an index mechanism 202 that supports a multi-pole armature 201 and sequentially sends a magnetic pole 201a that is a core of the multipole armature 201 to a winding position. A pair of formers 206 sandwiching the magnetic pole 201a from the vertical direction in the figure is used as a guide member for guiding the magnetic pole 201a. Each former 206 is constituted by a pair of divided pieces 206a which are separated from each other in the front and back direction of the figure, and thereby the former 206 which is a guide member is constituted by four divided pieces 206a. In addition to the main spindle 207 provided with the flyer 203, the winding device 200 is arranged along a guide shaft 205 parallel to the rotation axis of the main spindle in order to cause the four divided pieces 206a to move independently. A pair of movable sub spindles 208a and 208b are provided.

  More specifically, the main spindle 207 provided with the flyer 203 is formed with a main through hole 209 through which the wire rod 204 sent to the flyer 203 is passed, and the first and second auxiliary spindles 208a and 208b have the wire rod. First and second sub through holes 210a and 210b that further pass through 204 are formed. A main center body 211 is coaxially supported on the main spindle 207, and first and second sub center bodies 212a and 212b are coaxially supported on the first and second sub spindles 208a and 208b, respectively. The main center body 211 and the first sub-center body 212a are arranged on the same axis, and the first sub-center body 212a and the second sub-center body 212b are offset and arranged so as to be parallel to each other.

  A first rod 213 is provided through the rotation center of the main center body 211 and the first sub center body 212a, and the first rod 213 is spline-engaged with the main center body 211 and the first sub center body 212a. . The first rod 213 is connected to the second sub-center body 212b by a joint 214. Thus, by connecting the main center body 211 and the second sub-center body 212b that are offset so as to be parallel to each other via the joint 214, the first rod 213 and the first rod 213 are spline-engaged. Relative rotation of the main central body 211 is prohibited. For this reason, the former 206, which is a guide member, is attached to the main central body 211, which is prohibited from rotating, so that the former 206 can be held stationary.

  The main central body 211 is provided with a pair of second rods 216 and 216 that are parallel to the first rod 213 and sandwich the first rod 213 from above and below. A first cam 213a is provided at the front end of the first rod 213 to separate the pair of formers 206 in the vertical direction. A split piece 206a forming the former 206 is formed at the front ends of the pair of second rods 216, 216. Second cams 216a for making contact with each other in the front and back direction of the paper surface are provided. The rear ends of the second rods 216 and 216 are fixed to a first sub-center body 212a supported by the first sub-spindle 208a. The winding device 200 includes a main movement motor 217 that moves the main spindle 207 in the axial direction, a first sub movement motor 218 that moves the first sub spindle 208a in the axial direction, and a second sub spindle 208b. A second auxiliary movement motor 219 is provided for moving in the axial direction.

  The main moving motor 217 changes the position of the wire 204 fed out from the flyer 203 by moving the main spindle 207 together with the flyer 203 in the axial direction. The first sub-movement motor 218 moves the pair of second rods 216 and 216 in the axial direction together with the first sub-spindle 208a, so that the divided piece 206a that forms the former 206 via the second cam 216a is removed from the paper surface. It is separated from the front and back. Further, the second secondary movement motor 219 moves the first rod 213 in the axial direction together with the second secondary spindle 208b, thereby bringing the pair of formers 206, 206 into and out of contact with each other via the first cam 213a. Is. Thus, even if a guide member composed of a plurality of divided pieces 206a is provided, a plurality of rods 213 and 216 that give movement to the plurality of divided pieces 206a are provided, and the number of the rods 213 and 216 corresponds to the number of the plurality of rods 213 and 216. By increasing the number of the spindles 208a and 208b for independently moving the rods 213 and 216, independent movement can be generated in the plurality of divided pieces 206a.

  On the other hand, in the conventional winding apparatus 200 shown in FIG. 12, since the flyer 203 rotates together with the main spindle 207, the wire 204 is attached to the main spindle 207 in order to prevent the wire 204 guided to the flyer 203 from being entangled. The first and second sub spindles 208a and 208b are sequentially passed through the main through hole 209 and the first and second sub through holes 210a and 210b formed in the first and second sub spindles 208a and 208b. The relative positional relationship between the nozzles 209, 210a, and 210b through which the wire 204 is passed needs to be not rotated significantly by being rotated together with the spindle 207. The winding device 200 includes a flyer rotation motor 221 that rotates the main spindle 207 together with the flyer 203, but the first and second auxiliary spindles 208a are provided by motors 222 and 223 provided separately from the flyer rotation motor 221. 208b are rotated in synchronization with the main spindle 207.

JP 2008-61310 A

  However, the winding device 200 already includes motors 217 to 219 for moving the spindles 207, 208a, and 208b in the axial direction. In addition to the motors 217 to 219, the spindles 207, 208a, and 208b are synchronized. If the separate motors 221 to 223 are used only for rotation, the number of motors used in the winding device 200 is unnecessarily increased. In particular, when a guide member 206 composed of a plurality of divided pieces 206a is provided and a new spindle is added to cause independent movement for each of the plurality of divided pieces 206a, a further spindle is further rotated to rotate the added spindle. A new motor is required. For this reason, if the motors 221 to 223 for rotating the spindles 207, 208a, and 208b are provided for the respective spindles 207, 208a, and 208b, the number of motors is remarkably increased and the control of the increased motors is complicated. there were.

  In particular, in the conventional winding apparatus 200 shown in FIG. 12, the first auxiliary spindle 208a is moved in the axial direction separately from the main moving motor 217 that moves the main spindle 207 provided with the flyer 204 in the axial direction. A secondary movement motor 218 and a second secondary movement motor 219 for moving the second secondary spindle 208b in the axial direction are provided. Therefore, in order to prevent the relative movement of the former 206 with respect to the main spindle 207 when the main movement motor 217 is driven to move the main spindle 207 in the axial direction, the first and second sub movements are performed. The motors 218 and 219 are also driven simultaneously to move the first and second secondary spindles 208a and 208b in the axial direction together with the central bodies 212a and 212b. As a result, at the time of winding, these motors 217, 218, and 219 must always be driven simultaneously, and there is a problem that the control becomes more complicated.

  Further, in the conventional winding apparatus 200 shown in FIG. 12, the first rod 213 is connected to the second sub-center body 212 b using the joint 214, whereby a former that is a guide member provided on the main center body 211. Since 206 is held stationary, the first rod 213 and the second sub-center body 212b are jointed separately from the operation of supporting the first rod 213 coaxially with respect to the main and first sub-spindles 207 and 208a. The operation | work connected by 214 is required, and the increase in the number of parts which consist of the joint 214 and the increase in a connection operation | work will arise.

  Further, in the above-described conventional structure in which the first rod 213 is connected to the second sub-center body 212b using the joint 214, the plurality of divided pieces 206a constituting the guide member 206 are caused to move independently of each other. When the number is increased, the increased second rods 216 and 216 cannot be connected to the second sub-center body 212 b using the same joint 214. Therefore, it is necessary to provide a structure for supporting the increased second rods 216 and 216 on the main central body 211 separately from the first rod 213. In the winding device 200 shown in FIG. It is supported on the main central body 211 in parallel with one rod 213. For this reason, there is a problem that the structure of the main central body 211 is complicated and the main central body 211 is enlarged. That is, in the conventional structure using the joint 214, causing independent movements in the plurality of divided pieces constituting the guide member 206 causes further complication and enlargement of the structure, resulting in a winding device obtained as a result. There was a problem that the unit price of 200 was significantly increased.

  An object of the present invention is to provide a winding device that is relatively inexpensive by reducing the number of parts such as a motor necessary for stationary or moving a guide member.

  The present invention is provided with a main spindle provided with a main through hole through which a wire sent to the flyer is passed and a rotation shaft about which the flyer rotates, a motor that rotates the main spindle together with the flyer around the rotation shaft, This is an improvement of a winding device including a guide member that guides a wire rod fed from a flyer through a main through hole by rotation of the flyer to a winding core.

  The characteristic configuration is that a sub-spindle is provided with a sub-through hole through which a wire is passed, which is parallel to the rotation axis and is provided with a center axis that is offset from the rotation axis as a rotation center, and the sub-spindle with the center axis as the rotation center. A central body that is freely rotatable and a main member that passes through the main spindle and is freely rotatable with the rotation axis as a rotation center. A guide member is provided at one end or engaged, and the other end is offset from the central axis and fixed to the central body. And a rotation transmission mechanism for transmitting the rotation of the main spindle by the motor to the sub spindle and rotating the sub spindle synchronously with the main spindle.

  The rotation transmission mechanism includes a guide shaft provided in parallel with the rotation shaft of the flyer, and a main belt that is spanned between the main spindle and the guide shaft, transmits the rotation of the main spindle to the guide shaft, and rotates the guide shaft. And a secondary belt that is spanned between the guide shaft and the secondary spindle and transmits the rotation of the guide shaft to the secondary spindle to rotate the secondary spindle.

  It also includes a flyer moving mechanism that supports the rod slidably in the axial direction with respect to the main spindle, and a guide member moving mechanism that moves the sub spindle in the axial direction together with the central body. it can.

  The rod has a first rod and a second rod inserted into the first rod, and the secondary spindle rotatably supports the first central body and the second central body. If the second sub spindle is provided, the guide member may have a pair of center formers engaged with one end of the first rod and a pair of side plates engaged with one end of the second rod. The other end of the first rod can be fixed to the first central body, the second rod can be passed through the first central body, and the other end can be fixed to the second central body.

  The winding device of the present invention includes a flyer rotation motor that rotates the main spindle together with the flyer. However, since the rotation of the main spindle is transmitted to the sub spindle by the rotation transmission mechanism, the sub spindle is separated from the motor that rotates the flyer. It is not necessary to use a motor for rotating. For this reason, even if the guide member is composed of a plurality of components such as a center former and a side plate, and a new secondary spindle is added to cause independent movement thereof, a new motor is added for the added secondary spindle. Is never needed. Therefore, the number of motors can be reduced as compared with the conventional case where a motor for rotating the secondary spindle is provided separately from the flyer rotating motor, and a relatively inexpensive winding device can be obtained. .

  In addition, if the rotation of the main spindle is transmitted to the sub spindle by a belt via a conventionally provided guide shaft, it is possible to avoid the generation of new parts for the transmission. Even in assembly, it can be performed by a simple operation of simply wrapping the belt. Therefore, the assembly and adjustment can be facilitated, and a more inexpensive winding device can be obtained.

  On the other hand, if a flyer moving mechanism that moves the main spindle in the axial direction and a guide member moving mechanism that moves the auxiliary spindle in the axial direction together with the central body, the flyer moves independently of the movement of the guide member. It becomes possible.

  Further, if the rod is a plurality of rods such as a first rod and a second rod inserted through the first rod, the plurality of rods can be provided coaxially on the main spindle provided with the flyer. As compared with the conventional structure in which the plurality of rods are provided in parallel, the structure in which the plurality of rods are provided can be simplified. Then, if the secondary spindle is increased in proportion to the number of the plurality of rods and the other ends of the plurality of rods are separately fixed to the respective central bodies of the plurality of secondary spindles, the center former or side can be used as a guide member. Even if a plurality of members such as plates are provided, independent movement of the plurality of members constituting the guide member is relatively easy by separately providing or engaging one end of a plurality of rods with the plurality of members. Can be generated.

  Then, the other end of the rod is eccentrically fixed to the central body directly from the central axis so that the central body is restrained by the rod and does not rotate. Since the central body does not rotate, the rod having the other end fixed to the central body does not rotate, and the guide member provided or engaged with one end of the rod is stationary with respect to the core. Can be held. Therefore, the present invention does not use a joint conventionally required to hold the guide member in a stationary state. Further, the conventionally required work for connecting the joints becomes unnecessary, the number of parts is further reduced, and a more inexpensive winding device can be obtained.

The guide rail 34 is engaged. And the roller 35c is each provided in those opposing parts and the both inner sides of the Y-axis direction. The first cam 45 provided at one end of the first rod 44 is advanced to pass through the opening 33a (FIG. 2) of the center former support plate 33 so that the tapered shape 45a contacts the roller 35c. Placed in. As shown in FIG. 2, the taper shape 45 a of the first cam 45 is tapered toward the multipole armature 1, and the taper shape 45 a in contact with the roller 35 c advances toward the multipole armature 1. Accordingly, the pair of vertical movement plates 35a and 35b are configured to be expanded against the urging force of the spring 36 and to move away from each other in the Z-axis direction, that is, in the vertical direction.

  Thus, by moving the first cam 45 forward, the pair of center formers 15, 16 move away from each other, and by moving the first cam 45 backward, the pair of center formers 15, 16 cause the biasing force of the spring 36. It is comprised so that it may move to the direction approached by. Accordingly, the vertical moving plates 35a, 35b, the spring 36, and the first cam 45 move the pair of center formers 15, 16 so as to move away from each other in the rotation axis direction of the multipolar armature 1. The one end of the first rod 44 is engaged with the pair of center formers 15 and 16 via the former separating / connecting mechanism 41.

  As shown in FIGS. 2 and 3, a second cam 48 is connected to the tip of a second rod 47 that is inserted through the first rod 44 so as to be movable in the axial direction. Opposing surfaces 38c of the pair of moving plates 38a, 38b are formed in a symmetrical inclined surface extending toward the multipole armature 1 (FIG. 3).

The The trapezoidal second cam is disposed so that the inclined surfaces 48a on both sides of the trapezoidal second cam abut against the opposed inclined surfaces 38c of the pair of moving plates 38a, 38b by retreating together with the second rod 47.

  Since the inclined surfaces 38c of the pair of moving plates 38a and 38b are formed opposite to the inclined surface 48a of the second cam 48, the second cam 48 is inclined by retreating between the pair of moving plates 38a and 38b. When the surface 48a abuts on the inclined surface 38c, the pair of moving plates 38a and 38b are pushed and spread against the urging force of the springs 40a and 40b, and move in the horizontal direction. As described above, the pair of side plates 39 and 39 are moved away from each other by moving the second cam 48 backward, and the pair of moving plates 38a and 38b are moved by the springs 40a and 40b by moving the second cam 48 forward. It moves in the direction approached by the urging force. Therefore, the moving plates 38a and 38b, the springs 40a and 40b, and the second cam 48 move the pair of side plates 39 and 39 so as to be separated from each other in the Y-axis direction that is the circumferential direction of the multipolar armature 1.

  The winding device 100 also includes a flyer moving mechanism 18 that moves the flyer 4 and the center formers 15 and 16 together with the main spindle 24 in the X-axis direction that is the axial direction thereof. The flyer moving mechanism 18 includes a traverse motor 50 provided on the base 5, a ball screw 51 connected to the output shaft of the traverse motor 50 and extending in the rotation axis direction of the flyer 4, and a movement in which the ball screw 51 is screwed.

Composed. In this way, by driving the traverse motor 50, the flyer 4, the center formers 15 and 16, and the pair of side plates 39 and 39 can be moved in the direction of the rotation axis of the flyer 4. In addition, since the frame 57 is provided on the moving table 21 and the moving mechanism 17 including the first rod moving mechanism 55 and the second rod moving mechanism 56 is provided on the frame 57, the flyer moving mechanism 18 in this embodiment is The guide member moving mechanism 17 is moved together with the main spindle 24 in the axial direction of the main spindle 24. The flyer moving mechanism 18 moves the wire 3 in the X-axis direction by the outer diameter of the wire 3 every time the wire 3 is wound around the magnetic pole 2 during winding of the wire 3 around the magnetic pole 2. Used for.

  Further, in the vicinity of the index mechanism 7, there is used a work pressing mechanism 88 that holds the multipolar armature 1 against the index base 11 by holding it against the index base 11. This work presser mechanism 88 is connected to an armature presser motor 90 fixed to an end of a support column 89 erected on the base 5 and an output shaft of the armature presser motor 90, and is a rotary shaft of the multipole armature 1. A ball screw 91 extending in the direction, a moving body 92 to which the ball screw 91 is screwed, and a guide rail 93 arranged to extend in the vertical direction on the support 89 and guide the moving body 92 are provided. A rotatable rod 95 is provided on the side surface of the moving body 92 via a bearing 94. The rod 95 is disposed coaxially with the rotation axis of the multipole armature 1, and an armature pressing member 96 that contacts the annular portion 1 a of the multipole armature 1 is connected to the lower end of the rod 95.

  When the armature presser motor 90 is driven, the moving body 92 is guided by the guide rail 93, and the armature presser member 96 moves in the direction of the rotation axis of the multipolar armature 1. In this way, by driving the armature presser motor 90, the armature presser member 96 comes into contact with the upper surface of the annular portion 1a of the multipole armature 1 placed on the index base 11, and the multipole armature 1 is moved. Press against the index table 11. As a result, the multipole armature 1 is configured to be held between the index base 11 and the armature pressing member 96. Since the rod 95 connected to the armature presser member 96 is supported via the bearing 94, the armature presser member 96 is used as the multipole armature during rotation of the multipole armature 1 by driving the index motor 90. It depends on 1 and rotates.

  Around the multi-pole armature 1, there are magnetic poles on both sides of the magnetic pole 2 to be wound in order to prevent the wire 3 fed from the flyer 4 from being caught by the magnetic poles on both sides of the magnetic pole 2 to be wound. A pair of side formers 97 that respectively cover the flange portions 2a are disposed (see FIGS. 1 and 6). The side former 97 is formed in a curved surface shape that tapers toward the tip, is supported by a support column 98 standing on the base 5, and is configured to be movable by a mechanism (not shown).

  In addition, the winding device 100 includes an armature moving mechanism 99 for making the vertical position (height) of the multipole armature 1 coincide with the rotation axis of the flyer 4. This armature moving mechanism 99 is connected to the support 101 arranged on the base 5, the armature moving motor 102 arranged on the top surface of the support 101, and the output of the armature moving motor 102, and the multipole armature. A ball screw 103 extending in the direction of one rotation axis (vertical direction), a moving body 104 to which the ball screw 103 is screwed, and a guide rail that extends in the vertical direction to guide the moving body 104. 105.

  The moving body 104 is connected to an index motor mounting table 106 on which the index motor 9 is mounted. A guide rod 107 extending in the vertical direction is arranged on the opposite side of the ball screw 103 with the index motor mounting table 106 as the center, and a moving body 108 coupled to the index motor mounting table 106 slides on the guide rod 107. It is inserted freely. When the armature moving motor 102 is driven, the moving body 104 is guided by the guide rail 105 and the moving body 108 slides on the guide rod 107, and the index motor mounting table 106 moves in the vertical direction. Thereby, the multipole armature 1 supported by the index base 11 moves in the vertical direction. As described above, by driving the armature moving motor 102 in the armature moving mechanism 99, the vertical position (height) of the multipole armature 1 can be matched with the rotation axis of the flyer 4. Is done.

  Next, the operation of the winding apparatus 100 will be described. The operation of the winding apparatus 100 is automatically controlled by a controller (not shown) mounted on the winding apparatus 100.

  First, as preparation before winding, the wire 3 supplied from a wire supply source (not shown) is passed through a tension device (not shown) from the rear portion of the frame 57 to the second secondary spindle 77. The sub through hole 77a, the first sub through hole 62a of the first sub spindle 62, and the main through hole 24b of the main spindle 24 are sequentially passed to the nozzle 27 at the tip of the flyer through a plurality of rollers 4a. Lead. Then, the wire 3 drawn out from the nozzle 27 is locked to a pin 1 d provided on the annular portion 1 a of the multipole armature 1.

  Next, the multipole armature 1 is placed on the index base 11 such that the shaft 11a is inserted into the through hole 1c. In this state, the multipole armature 1 and the winding mechanism 6 are aligned. That is, by driving the armature moving motor 102 of the armature moving mechanism 99, the vertical position (height) of the multipole armature 1 and the rotation axis of the flyer 4 are matched. That is, the winding center axis of the magnetic pole 2 to be wound and the rotation axis of the flyer 4 are adjusted to be the same height. After the adjustment, by driving the armature presser motor 90, the armature presser member 96 is lowered toward the multipolar armature 1 and pressed against the annular portion 1a. In this way, the multipolar armature 1 is supported between the index base 11 and the armature pressing member 96.

  Next, the multi-pole armature 1 is rotated by driving the index motor 9, and the magnetic pole 2 to be wound among the plurality of magnetic poles 2 is set at the winding position. Specifically, the magnetic pole 2 to be wound is aligned with the rotation axis direction of the flyer 4. Thus, the position facing the rotation axis of the flyer 4 is the winding position. Although not shown, the alignment of the multipole armature 1 to the winding position is performed by detecting the position of the magnetic pole 2 using a detector (not shown) such as a sensor provided in the vicinity of the magnetic pole 2 and detecting the detected information. On the basis of

  Next, the traverse motor 50 of the flyer moving mechanism 18 is driven to advance the mounting wall 22 together with the moving base 21, and the flyer 4, the pair of center formers 15, 16 and the pair of side plates 39, 39 are brought into the winding position. It arrange | positions at the base end part of the arrange | positioned magnetic pole 2. As shown in FIG. 6 and 7, the tip edges 15a, 16a of the pair of center formers 15, 16 and the annular portion 1a of the multipole armature 1 and the leading edges of the pair of side plates 39, 39 are provided. It arrange | positions so that the clearance gap which the wire 3 can approach will leave the both between 39b and the cyclic | annular part 1a in the multipolar armature 1. FIG.

  At this time, the pair of center formers 15 and 16 and the pair of side plates 39 and 39 which are guide members and sandwich the magnetic pole 2 are separated from each other as necessary. The pairing of the center formers 15 and 16 drives the first rod moving motor 71 in the first rod moving mechanism 55 to move the first rod 44 forward or backward together with the first cam 45. Accordingly, the pair of center formers 15 and 16 can be moved so as to be separated from or approach each other in the vertical direction (the rotation axis direction of the multipole armature 1). The amount of movement in the Z-axis direction of each of the pair of center formers 15 and 16 can be adjusted by the amount of advancement of the first cam 45.

  In order to move the pair of side plates 39, 39 apart, the second rod moving motor 85 in the second rod moving mechanism 56 is driven, and the second cam 48 is moved backward or forward together with the second rod 47. Thereby, a pair of side plates 39 and 39 can be moved so that it may mutually separate or approach in the width direction of the magnetic pole 2 arrange | positioned in the coil | winding position. The amount of movement of the pair of side plates 39, 39 in the Y-axis direction can be adjusted by the amount of retraction of the second cam 48. The above is preparation before winding.

  Next, the winding started in the state described above will be described.

  With the flyer 4 positioned vertically above the magnetic pole 2, the flyer rotation motor 29 is driven to rotate the flyer 4 together with the main spindle 24. Then, the flyer 4 is rotated around the magnetic pole 2, and the wire 3 fed from the flyer 4 is wound around the magnetic pole 2. The rotation of the main spindle 24 is transmitted to the first sub spindle 62 and the second sub spindle 77 via the guide shaft 58 in the rotation transmission mechanism 12, and in synchronization with the rotation of the flyer 4, The spindle 77 also rotates. Thereby, the wire rod 3 supplied from the wire rod supply source can be guided to the nozzle 27 without twisting.

  In the process in which the winding is started and the flyer 4 is rotated 180 ° from the vertically upper side to the vertically lower side of the magnetic pole 2, the wire 3 fed out from the flyer 4 comes into contact with the side former 97 and is guided along the slope. At the same time, it comes into contact with the center former 15 and the side plate 39, slides down the curved surface, is guided to the magnetic pole 2 from the tip thereof, and is wound around the magnetic pole 2. In the process in which the flyer 4 is rotated 180 ° from the vertically lower side to the vertically upper side of the magnetic pole 2, the wire 3 fed out from the flyer 4 comes into contact with the side former 97 and is guided along the inclined surface. Abutting against the center former 16 and the side plate 39, sliding down the curved surface thereof, being guided to the magnetic pole 2 from the tip thereof, and wound around the magnetic pole 2. Thus, as the flyer 4 makes one rotation, the wire 3 is 1 to 2 turns.

  Since the center formers 15 and 16 and the side plates 39 which are guide members guide the wire 3 with respect to the fixed magnetic pole 2, it is not allowed to rotate together with the flyer 4. In order to prevent the center formers 15 and 16 and the side plates 39 and 39 from rotating, in the present invention, the guide members 15, 16 and 39 are engaged with one ends of the rods 44 and 47, and the rods 44 and 47 are engaged. And the other end of the rods 44, 47 coaxial with the rotation axis T of the main center body 26 are provided at the first and second center bodies 64,. 79 is fixed eccentrically from its central axis C. For this reason, the first and second central bodies 64 and 79 are restrained by the rods 44 and 47 and do not rotate. If the first and second center bodies 64 and 79 do not rotate in this way, the first and second rods 44 and 47 whose other ends are fixed to the first and second center bodies 64 and 79 also rotate. In other words, the main central body 26 to which the first rod 44 is spline-engaged cannot be rotated. The center former support plate 33 is attached to the front end surface of the main center body 26 which cannot be rotated in this way, and the center former support plate 33 is provided with the center formers 15 and 16 and the side plates 39 and 39, so that a guide member comprising them is provided. Is prevented from rotating together with the flyer 4 around the rotation axis T.

  In the winding to the magnetic pole 2, when the flyer 4 is rotated once to wind the wire 3 around the magnetic pole 2 that is the core, the wire is wound on the last surface (for example, the upper surface) of the four surfaces of the magnetic pole 2. When winding 3, the traverse motor 50 in the flyer moving mechanism 18 is driven to wire the flyer 4, the center formers 15 and 16, and the pair of side plates 39 and 39 in the winding direction (the radial direction of the magnetic pole 2). It is moved away from the multipolar armature 1 by the outer diameter of 3. Here, the flyer 4 is provided on the main spindle 24, and the center formers 15, 16 and the pair of side plates 39, 39 are provided on the main center body 26 supported by the main spindle 24, so that the traverse motor 50 is driven. Thus, the center formers 15 and 16 and the pair of side plates 39 and 39 can be simultaneously moved in the same direction together with the flyer 4 simply by moving the main spindle 24 in the axial direction.

  Further, since the flyer moving mechanism 18 in this embodiment is configured to move the guide member moving mechanism 17 in the axial direction of the main spindle 24 together with the main spindle 24, the main spindle 24 can be simply driven by driving the traverse motor 50. 24 and the first and second secondary spindles 62 and 77 move in the same direction. For this reason, the first and second central bodies 64 and 79 are moved in the axial direction together with the first and second auxiliary spindles 62 and 77, so that the first and second rods 44 and 47 are also moved in the same direction. The relative movement of the pair of center formers 15 and 16 and the pair of side plates 39 and 39 with respect to the main spindle 24 is prohibited. That is, when the main spindle 24 is moved in the axial direction, the pair of center formers 15 and 16 are not separated from each other in the Z-axis direction without driving the first rod moving motor 71, and the second rod is moved. Even if the motor 85 is not driven, the pair of side plates 39, 39 are not separated from each other in the Y-axis direction. In this regard, in order to prevent relative movement of the former 206 with respect to the conventional main spindle 207, the first and second auxiliary movement motors 218 and 219 need to be driven simultaneously. Is different. In this way, the magnetic pole 2 is wound by feeding the outer diameter of the wire 3 on one predetermined surface (for example, the upper surface) of the four surfaces of the magnetic pole 2 along with one rotation of the flyer 4. The wire 3 can be wound in an array.

  When such aligned winding is repeated, the pair of side plates 39, 39 move in the X-axis direction, which is the radial direction of the multipole armature 1, and the flange 2a is formed in the opening 39a before the first-layer winding is completed. When entering, the flange 2a comes into contact with the lip of the opening 39a. In order to avoid the flange 2a from coming into contact with the edge of the opening 39a, the distance between the pair of side plates 39, 39 is increased. The pair of side plates 39 can be moved by driving the second rod moving motor 85 in the second rod moving mechanism 56 as described above.

  When such aligned winding is repeated, the pair of center formers 15 and 16 are also moved in the X-axis direction, which is the radial direction of the multipole armature 1, and before the first winding is completed, the tapered portions 15a and 15a, 16a will contact | abut to the collar part 2a. In order to avoid the tapered portions 15a and 16a from coming into contact with the flange portion 2a, the pair of center formers 15 and 16 are moved to widen the mutual distance. The pair of center formers 15 and 16 can be moved by driving the first rod moving motor 71 in the first rod moving mechanism 55 as described above.

  Thus, in the middle of the winding, the first and second rods 44 and 47 are moved in the axial direction as needed by the first and second rod moving mechanisms 55 and 56 which are the guide member moving mechanism 17, and guided. The pair of side plates 39, 39 and the pair of center formers 15, 16 which are members are separated from each other. Then, the pair of side plates 39 and 39 and the pair of center formers 15 and 16 for guiding the wire 3 fed out from the flyer 4 to the magnetic pole 2 as the winding core are moved as indicated by solid arrows in FIGS. Thus, the winding of the first layer can be finished.

  As shown in FIGS. 8 and 9, after the first layer winding is completed, the second and subsequent layers are wound on the first layer winding. The winding of the second layer rotates the traverse motor 50 in the direction opposite to that of the first layer, and brings the flyer 4, the center formers 15 and 16, and the pair of side plates 39 and 39 closer to the multipolar armature 1. To move. After the second layer winding is completed, the third layer winding can be further performed on the second layer winding in the same procedure as the first layer winding. it can. By repeating this process, a desired number of layers of windings can be applied to the magnetic pole 2 as the core as shown in FIGS.

  Thus, when the winding to one magnetic pole 2 is completed, the multi-pole armature 1 is rotated by driving the index motor 9, and the one magnetic pole 2 and another magnetic pole 2 are arranged at the winding position. Then, a new winding is started.

  As described above, the winding apparatus 100 of the present invention includes the flyer rotation motor 29 that rotates the main spindle 24 together with the flyer 4. Since the signal is transmitted to the sub spindle 77, a separate motor for rotating the first sub spindle 62 and the second sub spindle 77 is not used separately from the flyer rotation motor 29. For this reason, even if a further secondary spindle is added, a new motor is not required for the added secondary spindle. Therefore, the number of motors can be reduced as compared with the conventional winding device 200 (FIG. 12) in which a motor for rotating the auxiliary spindle is provided separately from the flyer rotating motor 29.

  Further, the rotation of the main spindle 24 is transmitted to the first sub spindle 62 and the second sub spindle 77 through the guide shaft 58 and belts 59c, 68, 83 which are conventionally provided. It is possible to avoid the occurrence of unnecessary parts. By using the belts 59c, 68, and 83, the assembly can be performed by a simple operation of simply wrapping the belts 59c, 68, and 83 on the pulley, and the adjustment thereof is facilitated. Therefore, since the number of work steps in assembly is reduced, it is avoided that the unit price of the winding device 100 is pushed up, and a relatively inexpensive winding device 100 can be obtained.

  Further, in the conventional winding apparatus 200 shown in FIG. 12, in order to prevent the relative movement of the former 206 with respect to the main spindle 207, the main and second motors 217 for moving the main spindle 207 are used together with the first and second motors. The first and second sub-movement motors 218 and 219 for moving the sub-center bodies 212a and 212b in the axial direction also need to be driven simultaneously. However, since the flyer moving mechanism 18 in the present embodiment shown in FIG. 1 is configured to move the guide member moving mechanism 17 in the axial direction of the main spindle 24 together with the main spindle 24, the traverse motor in the flyer moving mechanism 18 is used. The relative movement of the center formers 15 and 16 and the pair of side plates 39 and 39 with respect to the main spindle 24 can be prohibited only by driving 50. Therefore, compared with the conventional winding apparatus 200 which needs to drive all of those motors simultaneously, control of those motors can be simplified.

  Further, in this embodiment, although there are a plurality of first rods 44 and second rods 47, by inserting the second rod 47 through the first rod 44, the plurality of rods 44, 47 are main. The rotation axis T of the spindle 24 can be provided coaxially. For this reason, the main center body 26 provided with the plurality of rods 44 and 47 is not enlarged, and the structure of the main center body 26 is not complicated. Then, the secondary spindles 62 and 77 are increased according to the number of the plurality of rods 44 and 47, and the other ends of the plurality of rods 44 and 47 are connected to the central bodies 64 and 79 of the plurality of secondary spindles 62 and 77, respectively. Since the guide members are fixed separately from each other, even if the guide member is a plurality of guide members 15, 16 and a pair of side plates 39, 39, the guide members 15, 16, 39, 39 By independently engaging the ends of the plurality of rods 44 and 47, independent movement can be generated in the plurality of guide members 15, 16, 39, and 39.

  Further, in the winding device 100 of the present invention, the other end of the rods 44 and 47 is directly fixed to the first and second central bodies 64 and 79 by being eccentric from the central axis C, thereby making the guide member stationary. The joint 214 (FIG. 12) that is conventionally required is not used. This eliminates the need for the joint 214 and eliminates the conventionally required work of connecting the joint 214, further reducing the number of parts and reducing the connection work, and further reducing the winding cost. Device 100 can be obtained.

  In the above-described embodiment, the case where the guide member has the pair of center formers 15 and 16 and the pair of side plates 39 and 39 has been described. However, the guide member is not limited to these, As long as the wire 3 fed from the flyer 4 can be guided to the core 2, the guide member may have another shape.

  In the above-described embodiment, one end of the first rod 44 is engaged with the pair of center formers 15 and 16 as guide members via the former separating / connecting mechanism 41, and one end of the second rod 47 is connected to the plate separating / attaching. Although the case where it engages with a pair of side plates 39 and 39 which are guide members via the mechanism 42 was demonstrated, a guide member is directly or indirectly attached to the end of a rod, without providing the contact-and-separation mechanisms 41 and 42. It may be provided in the above.

  Further, in the above-described embodiment, the case where the rod has the first rod 44 and the second rod 47 inserted through the first rod 44 has been described. If the number of guide members further increases, the third rod may be further inserted through the second rod inserted through the first rod 44.

  Further, in the above-described embodiment, the case where the winding core is the magnetic pole 2 of the multipole armature 1 has been described. However, the winding core around which the winding device 100 of the present invention winds the wire 3 is the multipole armature 1. However, the bobbin or the like in the transformer may be used as the winding core.
