Description:
BACKGROUND OF THE INVENTION  
         [0001]    [0001] 1 . Field of the Invention  
           [0002]    The present invention relates to a method and apparatus for winding wire around the outer periphery of a rotating wind-up tool of which the periphery is parallel to its axis of rotation, or a method and apparatus for winding wire around the outer periphery of a stationary wind-up tool of which the periphery is parallel to its axial center line.  
           [0003]    2. Description of the Related Art  
           [0004]    Hitherto, a winding mechanism with multi-spindles in which coil bobbins are rotated or fliers are rotated around stationary coil bobbins has been well known in the art. One of such apparatuses is shown in FIG.16.  
           [0005]    In the drawing, a plurality of spindles  105  are driven by a motor  106  by the medium of a motor pulley, pulleys  100   a ˜ 100   d  attached to the spindles  105 , and a belt  101 . This prior art is economical because only one driving source is used, but contains problems as follows:  
           [0006]    (1) the belt  101  looped over the motor pulley and pulleys  100   a ˜ 100   d  wears and gets longer with increasing use resulting in slack in the belt, which causes the deviation of rotation position due to the riding of the teeth of the belt across the teeth of the pulleys.  
           [0007]    For this reason, in the case the bobbin rotates(shaft rotation type wire winder), the deviation of rotation position develops even if the motor is stopped at a predetermined position. Accordingly, when the wire paid out from a nozzle  12  is engaged to the terminal of the bobbin, failure of engagement occurs due to the deviation of position of the nozzle and terminal, and proper winding can not be performed.  
           [0008]    This is the same in the case of a flier type wire winder with a flier turning around the bobbin.  
           [0009]    Even if the riding across of the teeth does not occur, there remains a problem that backlash develops in the meshing part of the teeth of the belt and pulley due to slack in the belt resulting in reduced accuracy of positioning.  
           [0010]    (2) When the slack in the belt develops as mentioned above, it is necessary to adjust the position of idler pulleys in order to keep the tension of the belt, or to replace the belt if the slack is large, which demands much efforts for adjustment, maintenance, etc.  
           [0011]    (3) There is a problem of short life of bearings because radial loads are exerted on the bearings of the spindles by the tension of the belt.  
           [0012]    (4) As there are many mechanical contacting and moving parts such as the bearings of spindles, the belt and pulleys, bearings of idler pulleys, the idler pulleys and belt, etc., noise generated in these contacting parts is high, it becomes higher as the bearings wear and deteriorate.  
           [0013]    (5) As there are many mechanical contacting and moving parts energy loss in these parts is large accompanying the problem of heat generation due to friction.  
           [0014]    (6) As a plurality of pulleys and idler pulleys rotate together with the spindles, inertia moment is large, responsivity is poor, so there is a limit to the accuracy of motion at starting up with high speed, hard-stopping, etc.  
         SUMMARY OF THE INVENTION  
         [0015]    The present invention is made to solve the problems described above. An object of the invention is to provide a method and an apparatus for winding wire without the failure of engagement of the wire caused by the deviation of position of a nozzle and bobbin terminal.  
           [0016]    Another object of the invention is to provide a method and an apparatus for winding wire without using a belt transmission mechanism for drive a plurality of spindles by a driving source.  
           [0017]    A further object of the invention is to provide a method and an apparatus for winding wire having superior responsivity to command signals.  
           [0018]    The present invention is characterized in that, in a method of winding wire around the outer peripheries of a plurality of rotating wind-up tools of which the peripheries are parallel to their axes of rotation, each wind-up tool is installed on each of a plurality of spinning bodies rotatable about the same axis of rotation as that of the spinning body, an individual rotation driving source is provided for each spinning body, and wire is wound around each wind-up tool while each individual rotation source rotates in synchronism with each other.  
           [0019]    The present invention is a method for winding wire around the outer periphery of a wind-up tool while rotating the wind-up tool, the wind-up tool may be a bobbin or a core other than bobbin, the wire being wound around the core to be formed into a coil which is removed from the core after the winding.  
           [0020]    The invention has also a feature that, each of a plurality of wind-up tools are installed on each of a plurality of spinning bodies rotatable about the same axis of rotation as that of the spinning body, a rotation driving source is provided for each of the spinning bodies, and wire is wound around each wind-up tool while the rotation sources rotate in synchronism with each other.  
           [0021]    By the art like this, as a rotation driving source is provided for each wind-up tool unlike the case the wind-up tools are driven by a driving source using a belt, it is possible to engage wire without the failure caused by the deviation of position of a nozzle and bobbin terminal, and further, as a belt transmission mechanism is not used for driving a plurality of spindles by a driving source, there occurs no problem of slacken belt, and a wire winding method with superior responsivity to command signals can be obtained.  
           [0022]    Further, it is also an effective means of the present invention to establish a method in which the wires are supplied to the wind-up tools by way of nozzles, and the initial positions of the wires before winding are set by moving the nozzles up-and-down, right-and-left, and back-and-forth, or a method in which the nozzles are moved up-and-down, right-and-left, and back-and-forth corresponding to the wire winding motion to be adjusted to the proper position.  
           [0023]    With the technical art like this, as the initial position of each of a plurality of nozzles is set on the same position, the failure of engagement of the wire due to the deviation of position of the nozzle and the terminal for engagement is prevented. Further, as nozzles are moved up-and-down, right-and-left, and back-and-forth corresponding to the wire winding motion, the winding can be performed with accuracy.  
           [0024]    Accordingly, also thin wire can be wound with precision.  
           [0025]    It is also an effective means of the present invention to regulate the position of each nozzle by moving each nozzle in the direction of up-and-down, right-and-left, and back-and-forth by rotating an individual rotation driving source for each direction.  
           [0026]    It is desirable that, the rotation driving source is rotated by control pulses, feedback pulses with the same frequency as the control pulses are sent out from the rotation driving source, and the number of rotations of the rotation driving source is detected by counting the number of the feedback pulses which is the same as that of the control pulses.  
           [0027]    With the technical art like this, as the feedback pulses having the same frequency as the control pulses for driving the rotation driving source, the number of rotations of the rotation driving source is detected by counting the number of the feedback pulses, and the rotation driving source is stopped in response to the detected number of the feedback pulses, the position of the nozzle can be accurately controlled. The number of rotations of the rotation driving source for rotating the spindle is controlled, so the number of rotations of the wind-up tool can also be accurately controlled.  
           [0028]    As an apparatus for performing the present invention, here is proposed an apparatus for winding wire around the outer peripheries of a plurality of rotating wind-up tools of which the outer peripheries are parallel to their axes of rotation, wherein the apparatus comprises:  
           [0029]    a plurality of rotatable wind-up tool holders for attaching each of the wind-up tools,  
           [0030]    a plurality of rotation driving sources each of which is connected to each wind-up tool holder for rotating each wind-up tools, and  
           [0031]    a rotation control means for controlling the rotation driving sources for rotating the wind-up tools in synchronism with each other.

           [0034]    Accordingly, by the art like this, as a rotation driving source is provided for each wind-up tool unlike the case the wind-up tools are driven by a driving source using a belt, it is possible to engage the wires without the failure caused by the deviation of position of each nozzle and bobbin terminal, and further, as a belt transmission mechanism is not used for driving a plurality of spindles by a driving source, there occurs no problem of slacken belt, and a wire winding method with superior responsivity to command signals can be obtained.

           [0040]    With the technical art like this, as the initial position of each of a plurality of nozzles is set on the same position, the failure of engagement of the wire due to the deviation of position of the nozzle and the terminal for engagement is prevented. Further, as each nozzle is moved up-and-down, right-and-left, and back-and-forth corresponding to the wire winding motion, the winding can be performed with accuracy.  
           [0041]    Accordingly, also thin wire can be wound with precision.  
           [0042]    It is also an effective means of the invention to constitute the apparatus for winding wire so that the rotation driving source is driven by control pulses, feedback pulses of the same frequency as the control pulses are sent out from the rotation driving source, and the number of rotations of the rotation driving source is detected by counting the number of the feedback pulses of which the frequency is the same as that of the control pulses.

As a guide screw is cut on the rotation shaft of the motor  13  and the threaded shaft passes through the guide screw hole in the slide plate  15  to move the slide plate back-and-forth as the motor  13  rotates, which makes possible the shift of nozzles  18  in back-and-forth direction.  
         [0114]    Accordingly, the horizontal longitudinal, horizontal lateral, and vertical positions of the nozzles  18  can be set.  
         [0115]    The wires  24  are supplied by way of a wire transit part  14  provided in the rear of the base frame  2 A. The wire transit part  14  consists of pillars  22  and tension causing parts  23  for causing tension to be generated in the wires. A spool  31  corresponding to each wire is provided, as shown in FIG. 4, in the rear of the base  1 .

         [0117]    Next, an embodiment of the bobbin installing part according to the first embodiment will be explained with reference to FIG. 5. In the drawing, the motor  9 A with an encorder  32  is attached to the winding head  25 A, and an end part  6 Aa of the spindle  6 A supported for rotation by bearings  33 ,  33  is inserted into the motor  9 A in the center.  
         [0118]    The end part  6 Aa of the spindle  6 A is, for example, shaped to have an oval section, and the oval-shaped part engages with the concave part of the motor side.  
         [0119]    A hole  6 Ab is machined on the right end of the spindle  6 A, the smaller diameter part  34 Ab of a winding jig  34 A is inserted into the hole  6 Ab to be fixed by a set screw  40 . A hole  34 Aa is machined in the center of the larger diameter part of the winding jig  34 A, and the rear end side  35   b  of a bobbin attaching shaft  35  is inserted into the hole  34 Aa to be fixed by a set screw  40 . A slit  35   a  is provided in the right end side of the bobbin attaching shaft  35  to cause friction between the shaft  35  and the bobbin  8 A in order to hold the bobbin  8 A on the shaft  35  so that the bobbin attached to the shaft  35  does not rotate and smooth winding is performed.  
         [0120]    Next, another embodiment of the bobbin attaching part according to the first embodiment will be explained with reference to FIG. 7. In the drawing, a motor  9 A with an encorder  32 A is attached to the winding head  25 B, and an end part  6 Ba of the spindle  6 B supported for rotation by bearings  33 ,  33  is inserted into the motor  9 A in the center.  
         [0121]    The end part  6 ba of the spindle  6 B is, for example, shaped to have an oval section, and the oval-shaped part engages with the concave part of the motor side.  
         [0122]    A screw is cut on the right end part  6 Bb of the spindle  6 B, a nut  41  is screwed in and also a winding jig  34 B is screwed in.  
         [0123]    The winding jig  34 B is, as shown in FIG. 8 , shaped like a cylinder having inner hollow space  34 Ba. Six through holes  34 Bb penetrate the cylinder wall radially as shown in FIG. 8, and in the through holes are inserted ball plungers  43   a,    43   b,  and a coil springs  44 . Each of the trough holes is shaped so that it is smaller in diameter at the inner hollow space side than at the outer periphery side of the cylindrical winding jig  34 B in order to prevent the dropping of the ball plungers  43 A into the inner hollow space  34 Ba.  
         [0124]    A plunger pusher  38  is put on the outer periphery of the winding jig  34 B slidable in back-and-forth direction(right-and-left direction in FIG. 7 and FIG. 8). A spring  39  is inserted between the flange part at the rear end of the winding jig  34 B and the rear end face  38   a  of the plunger pusher  38 , the plunger pusher  38  is stopped by a nut  51  screwed on the forward end part of the winding jig  34 B, and the spring  39  exerts force on the rear end face  38   a  of the plunger pusher  38  in the forward direction. The plunger pusher  38  has a cone-shaped cam face  38   b  which tapers in the backward direction. Accordingly, when the plunger pusher  38  is in the state being stopped by the nut  51 , the pushing force of the plunger ball  43   a  toward the inner hollow space is large, and when the plunger pusher  38  is moved toward left in FIG. 7, the pushing force of the plunger ball  43   a  toward the inner hollow space is decreased.  
         [0125]    A passing jig  42  is inserted in the inner hollow space  34 Ba, a groove  42   d  is machined on the inserted part of the passing jig. When the passing jig  42  is inserted, the ball plunger  43   a  contacts on the bottom and/or inclined side face of the groove  42   d  to fix the passing jig  42  concerning the axial direction. The passing jig  42  is fixed concerning the circumferential direction by the fitting of the convex part provided on the passing jig with the notch provided in the winding jig  34 B. A hole  42   a  is machined in the center of the larger diameter part of the passing jig  42 , and rear end part  35   b  of the bobbin attaching shaft  35  is inserted into the hole  42   a  to be fixed by a set screw  40 . The right end part of the bobbin attaching shaft  35  tapers in a point, and a slit is machined to cause friction between the shaft  35  and the bobbin  8 A in order to hold the bobbin  8 A on the shaft  35  so that the bobbin attached to the shaft  35  does not rotate and smooth winding is performed.  
         [0126]    In FIG. 7, an air cylinder  36  is provided below the bearings  33  of the winding head  25 B, a cylinder shaft  45  protrudes in the forward direction from the air cylinder  36 , and a remover handle  37  is fixed to the end of the cylinder shaft  45 . The remover handle  37  has at the forward end an upright wall part  37   a  which can engages the flange part  38   a  of the plunger pusher  38 . Accordingly, when the cylinder shaft  45  is moved leftward by the operation of the air cylinder  36 , the upright wall part  37   a  of the remover handle  37  engages the flange part  38   a  of the plunger pusher  38  to move it leftward. When the plunger pusher is moved leftward, the pushing force of the ball plungers  43   a  decrease, and the passing jig  42  can be removed from the winding jig  34 B.  
         [0127]    Next, an electric block diagram of the control device of the embodiment will be explained with reference to FIG. 13. In the drawing, an electric control device  62  having a CPU inside it and an interface on each of input and output side, is controlled by the control program of a program input device  61 .  
         [0128]    The electric control device  62  is so configured so that, a spindle control circuit  80  for individually controlling a plurality of spindles is connected with a nozzle position control circuit  81  for controlling the position of nozzles for supplying wire, the spindle control circuit  80  and nozzle position control circuit  81  consists of a plurality of circuits respectively, and these circuits can be controlled in synchronism with each other respectively.  
         [0129]    The spindle control circuit  80  has an individual circuit for each of the individual spindles, each circuit controls the motors  9  of which each motor shaft is part of each spindle, each motor having a directly-coupled encorder  32 . The motor  9  is connected to the output terminal of the electric control device  62  by way of a counter  63 , a D/A converter  64 , and an amplifier  65 , starts to rotate by the control pulses of the electric control device  62 , and stops the rotation when the number of the feedback pulses sent forth by the encorder  32  coincides with that of the control pulses inputted.  
         [0130]    The encorder  32  is configured so that it sends forth a datum position pulse when the rotation shaft of the motor  9  comes to a predetermined position in a rotation.  
         [0131]    Accordingly, the electric control device  62  sends forth the control pulses to allow the motor  9  to rotate until the datum position pulse comes in, and when it stops to send forth the control pulses, the spindle is set on the initial rotation position owing to the fact that the motor is automatically stopped by the feedback pulses. With this positioning, the wires  24  are engaged to the terminals of the bobbins  8 , and after that the motors  9  are rotated for winding the wires around the bobbins  8 .  
         [0132]    The nozzle position control circuit  81  is a circuit for controlling the position of the nozzle fixing member  17  shown in FIG. 1. The position of the nozzle fixing member  17  in vertical, right-and-left, and back-and-forth direction, accordingly the positions of the nozzles, is controlled by the individual motor. The positions of the nozzles are required to be moved also in maintenance work other than when winding is carried out.  
         [0133]    The nozzle position control circuit  81  is of the same configuration as the spindle control circuit  80 .  
         [0134]    A vertical direction control circuit  82  for controlling the vertical position of the spindles is to control the motor  53  of which the motor shaft is connected to the frame  12 , the motor having a directly-coupled encorder  69 . The motor  53  is connected to the output terminal of the electric control device  62  by way of a counter  66 , a D/A converter  67 , and an amplifier  68 , starts to rotate by the control pulse of the electric control device  62 , and stops the rotation when the number of the feedback pulses sent forth by the encorder  69  coincides with the number of the control pulses inputted.  
         [0135]    The encorder  69  is configured so that it sends forth a datum position pulse when the rotation shaft of the motor  53  comes to a predetermined position in a rotation.  
         [0136]    Accordingly, the electric control device  62  sends forth the control pulse to allow the motor  53  to rotate until the datum position pulse comes in, and when it stops to send forth the control pulse, the frame  12  is set on the initial rotation position owing to the fact that the motor is automatically stopped by the feedback pulses.  
         [0137]    Similarly, a right-and-left direction control circuit  83  is to control the motor  19  of which the motor shaft is connected to the frame  12  by the medium of belt and pulley, the motor having a directly-coupled encorder  73 . The motor  19  is connected to the output terminal of the electric control device  62  by way of a counter  70 , a D/A converter  71 , and an amplifier  72 , starts to rotate by the control pulses of the electric control device  62 , and stops the rotation when the number of the feedback pulse sent forth by the encorder  73  coincides with the number of the control pulses inputted.  
         [0138]    Similarly, a back-and-forth direction control circuit  95  is to control the motor  13  which is mounted on the frame  12  and of which the motor shaft is connected with the slide plate  15  by the guide screw of the motor shaft, the motor  13  having a directly-coupled encorder  95 . The motor  13  is connected to the output terminal of the electric control device  62  by way of a counter  74 , a D/A converter  75 , and an amplifier  76 , starts to rotate by the control pulses of the electric control device  62 , and stops the rotation when the number of the feedback pulses sent forth by the encorder  95  coincides with the number of the control pulses inputted.  
         [0139]    Each of these encorders  69 ,  73 , and  95  is configured so that it sends forth a datum position pulse when the rotation shaft of each of the motors  53 ,  19 , and  13  comes to a predetermined position in a rotation.  
         [0140]    Accordingly, the electric control device  62  sends forth control pulses to allow each of the motors  53 ,  19 , and  13  to rotate until each datum position pulse comes in, and when it stops to send forth the control pulses, the nozzle fixing member  17  is set on the initial position owing to the fact that each of the motors is automatically stopped by the feedback pulses of which the number of pulses coincides with that of the control pulses.  
         [0141]    With this positioning, the wires  24  are engaged to the terminals of the bobbins  8 , and after that the motors  9  are rotated for winding the wires around the bobbins  8 .  
         [0142]    A signal wire of a magnetic valve  79  for switching the air supplied from an air compressor  59  to the air cylinder  36  through a piping  60  is connected to the output terminal of the electric control device  62 .  
         [0143]    Next, the operation of the winding apparatus of the first embodiment configured as described will be explained.  
         [0144]    As shown in FIG. 4, the wire  24  from the spool  31  is stringed over the transit roller  57  and  58  for causing tension by the medium of magnetic braking, and the tip of the wire  24  is allowed to hang down from the nozzle  18  as shown in FIG. 1.  
         [0145]    Then, an input-output means  85  is manipulated to operate the nozzle position control circuit  81  in the state each bobbin  8  is attached to the bobbin attaching shaft  35  of each spindle.  
         [0146]    Hereupon, the vertical direction control circuit  82  starts operation to set the vertical position of the nozzles, then the right-and-left direction control circuit  83  starts operation to set the right-and-left positions of the nozzles, and after that the back-and-forth direction control circuit  84  starts operation to set the back-and-forth position of the nozzles.  
         [0147]    The spindle control circuit  80  starts operation in synchronism with the operation start of the nozzle position control circuit  81  to set each bobbin  8  on the predetermined angle position. With this condition, the tip of each wire  24  is pinched in the pinching part  78  of each clamp  77 , then each nozzle  18  turns around the terminal  8   b  of each bobbin  8  to engage the wire  24  to the terminal  8   b.  Then each wire  24  is cut with a cutter  79  in between the terminal  8   b  and pinching part  78 . The remainder of each wire  24  held by each clamp is discharged by opening the pinching part  78 .  
         [0148]    Next, when the input-output means  85  is manipulated to operate each spindle motor  9 A, each wire  24  is wound around each bobbin  8 A. In synchronism with the start of winding, the distance from the tip of each nozzle  18  to the outer periphery of each wire  24  wound around each bobbin  8  is controlled to be at the predetermined position by the vertical direction control circuit  82 , and the position of each nozzle  18  is controlled by the right-and-left direction control circuit  83  corresponding to each wound layer of wire and by the back-and-forth direction control circuit  84  corresponding to the number of turns.  
         [0149]    As the positions of the nozzles  18  are controlled by the vertical direction control circuit  82 , the right-and-left direction control circuit  83 , and back-and-forth direction control circuit  84 , the positions of nozzles from the outer periphery of the winding wires are controlled with good accuracy even when fine wires of diameter of about 0.02 mm are wound around bobbins.  
         [0150]    [0150]FIG. 3 is a perspective view of wire winding apparatus of the second embodiment according to the present invention, FIG. 4 is a perspective view showing the wire supply and positioning mechanism of the second embodiment, and FIG. 14 is the electric block diagram of a control device in the second embodiment.  
         [0151]    The wire winding apparatus of the second embodiment according to the present invention will be explained with reference to FIG. 3.  
         [0152]    The point of difference from the first embodiment is that, unlike the first embodiment in which the position of each nozzle assigned to each spindle is adjusted in the vertical, right-and-left, and back-and-forth direction by three motors, in the second embodiment, vertical and right-and-left direction control circuits are omitted, and a back-and-forth direction control circuit and a back-and-forth direction fine adjusting circuit are provided in the second embodiment.  
         [0153]    As shown in FIG. 4, a wire transit part  4  explained in FIG. 1 is provided in the rear of a base  1 , and winding heads  25 B(a˜d) are mounted on the base  1 , on each winding head  25 B being mounted a spindle, a spindle motor, and a bobbin which are explained in the explanation of FIG. 1  and shown in FIG. 5˜FIG. 9.  
         [0154]    Nozzle control parts  30 (four nozzle control parts in case shown in figure) fixed to pillars  92  provided on winding heads  25 (A˜d) of a wire winding part  3 B constitute wire tip position adjusting parts  5 B.  
         [0155]    As the construction of the nozzle control parts  30 (a˜d) are the same, the nozzle control part  30   a  in FIG. 4 will be explained. A first traverse platform  26  is provided in the nozzle control part  30   a  for slide in the longitudinal direction of a guide rail  30   b  guided by the same. A rotation shaft  28   a  connected with the rotation shaft of a first traverse motor  28  mounted on the pillar  92  has a guide screw cut on it, the rotation shaft  28   a  passes through a guide screw hole of the first traverse platform  26 , so the platform  26  can be slid in the longitudinal direction of the rotation shaft  28   a  as the motor  28  rotates.  
         [0156]    A second traverse platform  27  with a nozzle  18  fixed to it is provided in the frame part  26   a  of the first traverse platform  26  for slide in the longitudinal direction of a guide rail  29   b  guided by the same.  
         [0157]    A second traverse motor  29  is attached to the frame part of the first traverse platform on the right end face. A rotation shaft  29   a  connected with the rotation shaft of the second traverse motor  29  has a guide screw of which the pitch is smaller than that of the rotation shaft  28   a  cut on it, the rotation shaft  29   a  passes through a guide screw hole of the second traverse platform  27 , so the platform  27  can be slid in the longitudinal direction of the rotation shaft  29   a  as the motor  29  rotates.  
         [0158]    As the nozzle control part  30   a  is configured like this, the position of the nozzle in the vertical and right-and-left direction is fixed, and the initial position of the nozzle  18  can be set only in the back-and-forward direction by controlling the motor  28  and  29 . After the wire  24  is engaged to the terminal of the bobbin  8 , the motor  9 A is operated to wind the wire  24  around the bobbin  8 .  
         [0159]    Next, the electric block diagram of the control device of the second embodiment will be explained with reference to FIG. 14.  
         [0160]    In the drawing, an electric control device  62  having a CPU inside it and an interface on the input and output side, is controlled by the control program of a program input device  61 .  
         [0161]    The electric control device  62  is so configured so that, a spindle control circuit  80  for individually controlling a plurality of spindles is connected with a nozzle position control circuit  93  for controlling the position of nozzles for supplying wire, the spindle control circuit  80  and nozzle position control circuit  93  consists of a plurality of circuits respectively, and these circuits can be controlled in synchronism with each other respectively.  
         [0162]    The spindle control circuit  80  is the same as that shown in FIG. 13 and explanation is omitted.  
         [0163]    A nozzle position control circuit  93  is a circuit for controlling the position of the nozzles  18  shown in FIG. 3. The nozzle position is adjusted in the back-and-forth direction by a back-and-forth direction control circuit  84  and a back-and-forth direction fine adjusting circuit  91  using different motors respectively. The back-and-forth direction control circuit  84  is of configuration the same as that explained in the first embodiment. The back-and-forth direction control circuit  84  is to control the motor  28  connected to the first traverse platform  26  and having an encorder  94  fixed to it. The motor  28  is connected to the output terminal of the electric device  62  by way of a counter  74 , a D/A converter  75 , and an amplifier  76 , starts to rotate by the control pulses of the electric control device  62 , and stops the rotation when the number of the feedback pulses sent forth by the encorder  94  coincides with the number of the control pulses inputted.  
         [0164]    The back-and-forth direction fine adjusting control circuit  91  is to control the motor  90  connected to the second traverse platform  27  and having an encorder  89  fixed to it. The motor  90  is connected to the output terminal of the electric control device  62  by way of a counter  86 , a D/A converter  87 , and an amplifier  88 , starts to rotate by the control pulses of the electric control device  62 , and stops the rotation when the number of the feedback pulses sent forth by the encorder  89  coincides with the number of the control pulses inputted.  
         [0165]    These encorders  89  and  94  are configured so that each sends forth a datum position pulse when the rotation shaft of each of the motors  90  and  28  comes to a predetermined position in a rotation.  
         [0166]    Accordingly, the electric control device  62  sends forth control pulses to allow each of the motors  90  and  28  to rotate until each datum position pulse comes in, and when it stops to send forth the control pulse, the nozzle is set on the initial position owing to the fact that each of the motors is automatically stopped by the feedback pulse of which the number of pulses coincides with that of the control pulses.  
         [0167]    A signal wire of a magnetic valve  79  for switching the air supplied from an air compressor  59  to the air cylinder  36  through a piping  60  is connected to the output terminal of the electric control device  62 .  
         [0168]    Next, the operation of the winding apparatus of the second embodiment configured as described will be explained.  
         [0169]    As shown in FIG. 4 , the wire  24  from the spool  31  is stringed over the transit roller  57  and  58 , and the tip of the wire  24  is allowed to hang down from the nozzle  18  as shown in FIG. 3.  
         [0170]    Then, an input-output means  85  is manipulated to operate the nozzle position control circuit  93  in the state each bobbin  8  is attached to the bobbin attaching shaft of each spindle.  
         [0171]    Hereupon, the back-and-forth direction control circuit  84  starts operation to set the first traverse platform  26  on the initial position.  
         [0172]    The spindle control circuit  80  starts operation in synchronism with the operation start of the nozzle position control circuit  93  to set each bobbin  8  on the predetermined angle position. With this condition, the tip part of the wire  24  is engaged to the bobbin terminal, that is, the wire is turned around the terminal by hand or magic hand not shown. Then the tip part of the engaged wire is cut near the bobbin terminal.  
         [0173]    Then, whether the wire  24  is stringed from the bobbin terminal in the vicinity of the bobbin flange to the nozzle parallel to the inner face of the flange, that is, the wire  24  is stringed perpendicular to the bobbin axis, is checked visually or by an inspection means not shown. If the wire  24  is not stringed perpendicular, the input-output means  85  is manipulated in order to send a fine adjusting pulse from the electric control device  62  to move the second traverse platform back-and-forth to set nozzle position.  
         [0174]    Then, by manipulating the input-output means  85  to operate each spindle motor  9 , each wire  24  is wind around each bobbin. In synchronism with this start of winding, the position of each nozzle  8  is controlled by the back-and-forth direction control circuit  84  in correspondence to the number of turns of the wire  24 .  
         [0175]    As the wire  24  is wound after stringed about parallel to the inside faces of front side and back side flanges of the bobbin by fine-adjusting the position of the nozzle  18  by the back-and-forth direction control circuit  91 , it is prevented that the nozzle  18  is traversed with the wire  24  hitched on the inside faces of the bobbin.  
         [0176]    As shown in FIG. 4, in the case in which the bobbin has a plurality of sections, that is, in the case of a section winding bobbin having partitions (flanges) for partitioning the take-up part into a plurality of sections (for example, a high pressure ignition coil with a large number of turns of thin wire), by shifting the nozzle by the motor  28  (the first rotation driving source) in the winding part and by shifting the nozzle by the motor  29 (the second driving source) in the flange part, the nozzle is shifted by the second rotation driving source in the partition for partitioning the winding part of the wind-up tool. As the shift of the nozzle in the partition is shorter than that in the winding part, the shift of the nozzle in the flange parts, i.e. partitions, of a bobbin having a plurality of winding section can be done with accuracy.  
         [0177]    The wire winding apparatus of the third embodiment according to the present invention will be explained with reference to FIG. 10, 11, and  15 .  
         [0178]    [0178]FIG. 10 is a perspective view of the wire winding apparatus of the third embodiment, FIG. 11  is a section view showing the structure of flier and bobbin installing part of the third embodiment, FIG. 12 is a perspective view of FIG. 10, and FIG. 15 is the electric block diagram of a control device in the third embodiment.  
         [0179]    The point of difference from the first embodiment is that, unlike the first embodiment in which a bobbin is attached to each spindle, each spindle is movable in a back-and-forth direction, a flier is attached to each spindle, and a bobbin is provided facing each flier in the third embodiment. Therefore, the position of the wire is adjusted by moving a winding head  25 C back-and-forth instead of operating the wire position adjusting part  5 A (FIG. 1). A wire position adjusting part  5 C comprises winding heads  25 C, motors  28  for moving the winding heads  25 C back-and-forth, and encorders  94 .  
         [0180]    As shown in FIG. 10, a wire transit part  4  which has been explained in the explanation of FIG. 1 is provided in the rear of a base  1 , and on the horizontal plane  2 Ba of a base frame  2 B are mounted winding heads  25 C each of which is provided with each of spindles  6 C, spindle motors  9 , and fliers  46 . Bobbins  8  are attached to bobbin attaching parts  47 , each bobbin facing each of the fliers  46 .  
         [0181]    Next, the spindle  6 , spindle motor  9 , and flier  46  will be explained with reference to FIG. 11 and FIG. 12.  
         [0182]    In FIG. 11, a motor  9 B with an encorder  32 B is attached to the winding head  25 C, the spindle  6 C is supported by bearings  33 ,  33  for rotation with its end part  6 Ca inserted into the center of the motor  9 B and encorder  32 B.  
         [0183]    The end part  6 Ca of the spindle  6 C is, for example, shaped to have an oval section, and the oval-shaped part engages with the concave part of the motor side.  
         [0184]    A through hole  6 Cb is machined in the center of the spindle  6 C, and a wire  24  from the wire transit part  4  passes through the through hole  6 Cb.  
         [0185]    Fliers  46 (Aa, Ab) are attached to the right end part of the spindle  6 C by the medium of a fixing part  48  which is fixed by a set screw  40 . The flier  46 Aa is movable in the direction of the straight arrow in FIG. 12.  
         [0186]    The flier  46 Aa is provided with transit rollers  46 Ac and  46 Ad, and nozzle  46 Ae. The wire  24  can be supplied toward the bobbin  8  by way of the transit rollers  46 Ac and  46 Ad, and nozzle  46 Ae.  
         [0187]    A bobbin shaft holder part  50  is attached facing the flier  46 A to the attaching part  47 . The bobbin holder  50  has a hole  50   a  into which the rear end side  35   b  of a bobbin attaching shaft  35  is inserted to be fixed by a set screw  40 . A slit  35   a  is provided in the left end side of the bobbin attaching shaft  35  to cause friction between the shaft  35  and the bobbin  8 A in order to hold the bobbin  8 A on the shaft  35  so that the bobbin attached to the shaft  35  does not rotate and smooth winding is performed.  
         [0188]    As shown in FIG. 12, the winding head  25 C is movable in the direction of the straight arrow guided by a guide rail  49 , a guide screw is cut on the rotation shaft  28   a  connected to the motor  28 , the motor shaft  28   a  engages with the female guide screw cut in the winding head  25 C. Thus, the winding head  25 C is moved back-and forth as the motor  25 C rotates.  
         [0189]    Next, the electric block diagram of a control device of the third embodiment will be explained with reference to FIG. 15.  
         [0190]    In the drawing, an electric control device  62  having a CPU inside it and an interface on each of input and output side, is controlled by the control program of a program input device  61 .  
         [0191]    The electric control device  62  is so configured so that, a spindle control circuit  80  for individually controlling a plurality of spindles is connected with a nozzle position control circuit  95  for controlling the position of nozzles for supplying wire, the spindle control circuit  80  and nozzle position control circuit  93  consists of a plurality of circuits respectively, and these circuits can be controlled in synchronism with each other respectively.  
         [0192]    The spindle control circuit  80  is the same as that shown in FIG. 13 and explanation is omitted.  
         [0193]    A nozzle position control circuit  95  is a circuit for controlling the position of the nozzle  46 Ae shown in FIG. 11. The position of each nozzle is controlled through the back-and forth direction control circuits  96 (a˜d) by an individual motor. Each of the back-and-forth direction control circuits  96  is configured like that explained in the first embodiment.  
         [0194]    The back-and-forth direction control circuit  96  is to control the motor  28  having an encorder  94  and connected to the flier  46 . The motor  28  is connected to the output terminal of the electric control device  62  by way of a counter  74 , a D/A converter  75 , and an amplifier  76 . The motor  28  starts rotation by the control pulses from the electric control device  62 , and stops the rotation when the number of the feedback pulses sent forth by the encorder  32  coincides with that of the control pulses inputted.  
         [0195]    The encorder  94  is configured so that it sends forth a datum position pulse when the rotation shaft of the motor  28  comes to a predetermined position in a rotation.  
         [0196]    Accordingly, the electric control device  62  sends forth control pulses to allow each of the motor  28  to rotate until each datum position pulse comes in, and when it stops to send forth the control pulses, the nozzle is set on the initial position owing to the fact that each of the motors is automatically stopped by the feedback pulses of which the number of pulses coincides with that of the control pulses.  
         [0197]    With this positioning, the wires  24  are engaged to the terminals of the bobbins  8 , and after that the motors  9 B are rotated for winding the wires around the bobbins  8 .  
         [0198]    A signal wire of a magnetic valve  79  for switching the air supplied from an air compressor  59  to the air cylinder  36  through a piping  60  is connected to the output terminal of the electric control device  62 .  
         [0199]    Next, the operation of the winding apparatus of the third embodiment configured as described will be explained.  
         [0200]    As shown in FIG. 4, the wire  24  from the spool  31  is stringed over the transit roller  57  and  58 , and the tip of the wire  24  is allowed to hang down from the nozzle  46 Ae as shown in FIG. 11.  
         [0201]    Then, a input-output means  85  is manipulated to operate the nozzle position control circuit  81  in the state each bobbin  8  is attached to the bobbin attaching shaft  35  of each spindle.  
         [0202]    Hereupon, the back-and-forth control circuits  96 (a˜d) starts to operate, and the winding heads  25 C are set on their initial positions. Although the position of the nozzle  46 Ae relative to the inside face of the bobbin flange is predetermined according to the size of the bobbin, it is also possible to be adjusted by the input-output means  85  while visually observing.  
         [0203]    With this condition, the tip part of the wire  24  is engaged to the bobbin terminal, that is, the wire is turned around the terminal by hand or magic hand not shown. Then the tip part of the engaged wire is cut near the bobbin terminal.  
         [0204]    In synchronism with the completion of the initial position setting by the nozzle position control circuit  95 , the spindle position control circuit  80 (a˜d) starts operation to rotate the flier  46  to wind the wire  24  around the bobbin  8 . In synchronism with the start of winding, the position of the nozzle  18  is controlled by the back-and-forth direction control circuit  96 (a˜d) corresponding to the number of turns of the wire  24 .  
         [0205]    As heretofore detailed, according to the present invention, it is possible to engage wire without the failure caused by the deviation of position of the nozzle and bobbin terminal, because a driving source for rotating wind-up tool is provided for each wind-up tool in the first and second invention and because a driving source for rotating a wire supply part which supplies the wire to a stationary winding part is provided for each wire supply part in the third invention, unlike the case a plurality of wind-up tools are driven by a driving source by the medium of a belt.  
         [0206]    Further, as a belt transmission mechanism is not used for driving a plurality of spindles, wire winding is possible with superior responsivity to command signal.
