  The bobbin 3 is supported on the other end of the spindle shaft 2. The bobbin 3 includes a winding drum portion 3a around which the wire 4 is wound, and a flange portion 3b provided coaxially with the winding drum portion 3a at both ends of the winding drum portion 3a.

The winding mechanism 5 includes a tension applying mechanism 11 that applies a predetermined tension to the wire 4 supplied from the wire supply source 10 and a nozzle 12 that feeds the wire 4 supplied from the tension applying mechanism 11 in three axes orthogonal to each other. And a nozzle moving mechanism 13 that operates in the direction.

The nozzle 12 has a cylindrical shape and is supported by the nozzle support portion 14 in a direction orthogonal to the spindle shaft 2. The wire rod 4 is held by the nozzle 12 through the through hole of the nozzle 12.

The moving mechanism 18a extends in the horizontal front-rear direction, that is, extends in parallel with the spindle shaft 2, the moving mechanism 18b extends in the horizontal horizontal direction, and the moving mechanism 18c extends in the vertical direction. The Thus, the moving mechanisms 18 a to 18 c are arranged orthogonal to each other in the three axial directions, and the moving mechanisms 18 a to 18 c are connected via the moving table 17. The nozzle support portion 14 is connected to a moving base 17 of the moving mechanism 18a among the three sets of moving mechanisms 18a to 18c via a rod 19, and freely operates in three orthogonal axes when the nozzle moving mechanism 13 is driven. .

  The tape applying mechanism 6 is for attaching an insulating tape 20 to the wire 4 wound around the winding drum 3a for the purpose of fixing and insulating the wire 4 wound around the winding drum 3a. 7 is placed. The tape sticking mechanism 6 includes a tape chuck 22 composed of two flat plates for holding the insulating tape 20 supplied from the tape supply source 21, a chuck support portion 23 for supporting the tape chuck 22, and the chuck support portion 23 as the bobbin 3. And a cutter moving mechanism 24 for guiding the insulating tape 20 and a cutter 25 for cutting the insulating tape 20 held by the tape chuck 22.

  The chuck moving mechanism 24 is connected to the motor 26, a ball screw 27 connected to the output shaft of the motor 26 and extending in a direction parallel to the spindle shaft 2, and screwed into the ball screw 27 along the axial direction of the ball screw 27.

  The elevating mechanism 30 includes a cylinder 31 that is fixed to the moving base 28 and extends in the vertical direction, an electromagnetic valve 32 that opens and closes by a signal of a controller 40 described later, and a piston 33 that reciprocates inside the cylinder 31. A chuck support 23 is connected to the tip of 33.

  The cylinder 31 is a double rod cylinder. When compressed air from an air supply source (not shown) is supplied into the cylinder 31 by opening and closing the electromagnetic valve 32, the piston 33 reciprocates. As a result, the chuck support portion 23 is guided to the bobbin 3.

  The cylinder 31 includes an origin position sensor 35 as an origin position detector that detects whether or not the chuck support portion 23 is at the origin position, that is, whether the work position by the tape applying mechanism 6 is at the end position, and a chuck. An operation position sensor 36 as an operation position detector for detecting the current operation position of the support portion 23 is provided. The origin position sensor 35 outputs a signal when the piston 33 is at the origin position, and the operation position sensor 36 detects the current position of the piston 33.

  Reference numeral 40 denotes a controller that is mounted on the winding apparatus 100 and controls the operation of the entire winding apparatus. FIG. 2 is a block diagram showing the configuration of the controller 40.

  As shown in FIG. 2, the controller 40 has a CPU 41 as a center and a ROM 42, a RAM 43, an origin position sensor 35, and an operation position sensor 36 connected thereto, and the operation of the winding mechanism 5 and the tape applying mechanism 6 is performed. It is something to control.

  The ROM 42 stores a control program necessary for the processing operation of the CPU 41 and various setting values.

  The RAM 43 temporarily stores the control program read from the ROM 42 and various set values, and stores information read by the origin position sensor 35 and the operation position sensor 36.

  The controller 40 controls operations of the spindle motor 8, the tension applying mechanism 11, the nozzle moving mechanism 13, and the like of the winding mechanism 5 by a control program stored in the ROM 42. Further, the operation of the tape supply source 21, the chuck moving mechanism 24, the cutter 25 and the like of the tape applying mechanism 6 is controlled.

  Next, the operation of the winding device 100 by the controller 40 will be described with reference to FIGS. FIG. 3 is a flowchart showing the operation of the winding device 100, FIG. 4 is a diagram showing the operation of the tape applying mechanism 6, and FIG. 5 is a graph showing the temporal change of the nozzle speed and the origin position sensor output signal.

  First, the bobbin 3 is fixed to the spindle shaft 2 so that the axis of the bobbin 3 coincides with the spindle shaft 2. Further, the wire 4 supplied from the wire supply source 10 through the tension applying mechanism 11 is passed through the nozzle 12 supported by the nozzle support portion 14, and the wire 4 fed from the tip of the nozzle 12 is clamped (not shown). ) To hold.

  As the nozzle moving mechanism 13 operates, the nozzle 12 moves to the winding body 3a of the bobbin 3 along with the wire 4 and guides the wire 4 to the end of the winding body 3a. And while the spindle axis | shaft 2 rotates, the nozzle 12 moves to the other end from the one end of the winding drum part 3a, and the wire 4 is wound around the winding drum part 3a (FIG. 3 step 1).

  The nozzle 12 moves to the end of the winding body 3a, winds the wire 4 around the winding body 3a, and then, as shown in FIG. 4 (a), makes the wire 4 perpendicular to the end of the winding body 3a. And is moved to the terminal 3c of the bobbin 3 (step 2 in FIG. 3).

  The nozzle 12 binds the wire 4 to the terminal 3c. Further, by operating the chuck moving mechanism 24 in parallel with the binding operation, the winding drum portion 3a as shown in FIG. 4A is used for fixing and insulating a portion where the wire 4 is bent at a right angle. The insulating tape 20 is affixed to the wire 4 wound around (step 3 in FIG. 3). Specifically, the position of the chuck support portion 23 in the spindle axis direction is adjusted by the lateral movement mechanism 29. Further, the piston 33 inside the cylinder 31 moves toward the winding drum portion 3a by the operation of the electromagnetic valve 32 of the lifting mechanism 30, and the insulating tape 20 held by the tape chuck 22 of the chuck support portion 23 is moved to the winding drum portion. It sticks on the outer periphery of the wire 4 wound by 3a. After the insulating tape 20 is applied, the chuck support 23 is raised to return to the original position, that is, the original position by the operation of the electromagnetic valve 32 of the lifting mechanism 30, as shown in FIG.

  In the above step 3, it is confirmed whether or not the operation of attaching the insulating tape 20 by the tape applying mechanism 6 has been completed at a predetermined timing while the nozzle 12 is tangling the wire 4 to the terminal 3c. Specifically, it is confirmed by the origin position sensor 35 whether or not the chuck support portion 23 of the tape applying mechanism 6 has returned to the origin position (step 4 in FIG. 3). When the position of the piston 33 has returned to the uppermost part (origin position) in the cylinder 31, the origin position sensor 35 outputs a signal, and the return of the chuck support portion 23 to the origin position is confirmed. Thus, in Step 4, it is determined whether or not the tape applying mechanism 6 has returned to the origin position while the nozzle 12 is tangling the wire 4 to the terminal 3c.

  In step 4, when the origin position sensor 35 detects the return of the chuck support portion 23 to the origin position, that is, when it is determined that the tape application work by the tape application mechanism 6 has been completed, the nozzle 12 Since there is no possibility of interference with the tape applying mechanism 6, the nozzle 12 moves to the winding body 3a again without stopping after the end of the binding operation of the wire 4 to the terminal 3c (step 5 in FIG. 3). Then, returning to step 1, the winding operation is repeated again.

  FIG. 5 shows temporal changes in the nozzle speed and the origin position sensor output signal at this time. The solid line in the figure indicates the speed of the nozzle 12, and the dotted line indicates the output signal of the origin position sensor 35. When the chuck support 23 is at the origin position, the output signal of the origin position sensor 35 is ON. The origin position sensor 3 confirms whether or not the chuck support portion 23 has returned to the origin position at a predetermined timing (t in the figure) while the nozzle 12 is tangling the wire 4 to the terminal 3c. At this time, if the output signal of the origin position sensor 35 is ON as shown in FIG. 5, the nozzle 12 continues the next winding operation without stopping.

  In step 4, if the origin position sensor 35 cannot detect the return of the chuck support 23 to the origin position, that is, if it is determined that the tape application work by the tape application mechanism 6 has not been completed, the nozzle 12 stops once after the end of the binding operation of the wire 4 to the terminal 3c (step 6 in FIG. 3). Then, the process returns to Step 4 again, and after the origin position sensor 35 detects the return of the chuck support 23 to the origin position, the process proceeds to Step 5 to resume the winding operation. Thereby, interference with the nozzle 12 and the tape sticking mechanism 6 can be prevented.

  The above operation is repeated by forming a loop to form a multilayer coil. Note that the number of winding layers and the frequency of applying the insulating tape 20 to the wire can be arbitrarily set by a program stored in the ROM 42.

  In addition, if the current position of the chuck support 23 is continuously detected by constantly detecting the current position of the piston 33 by the operation position sensor 36, the chuck support 23 can reach a position where it does not interfere with the nozzle 12. If it has risen, it can be determined that the work of the tape applying mechanism 6 has been completed.

  According to the winding device 100 according to the first embodiment of the present invention described above, when the winding operation of the nozzle 12 and the work of the tape applying mechanism 6 do not interfere with each other, the binding operation of the nozzle 12 to the terminal 3c is performed. Since the transition to the winding operation from the winding body 3a to the winding body 3a is continuously performed without stopping, the winding work can be performed efficiently.

  Further, when there is a possibility that the winding operation of the nozzle 12 and the operation of the tape applying mechanism 6 interfere with each other, the operation of the nozzle 12 is temporarily stopped, but when the possibility of interference disappears, the operation of the nozzle 12 is stopped. To resume. Therefore, the winding operation can be performed more efficiently than when a predetermined time is set between the winding operation of the nozzle 12 and the operation of the tape applying mechanism 6. Time can be shortened.

(Embodiment 2)
Next, a winding apparatus 200 according to Embodiment 2 of the present invention will be described with reference to FIGS. 6 is a perspective view showing the winding device 200, and FIG. 7 is a partially enlarged view showing the periphery of the core.

The wire 4 is wound around the teeth 50b. Slots 50c are opened between the teeth 50b.

  A rotor shaft 52 is inserted through the opening of the annular portion 50 a of the core 50, and a commutator 53 is attached to the rotor shaft 52. The commutator 53 is provided with a terminal 54 that locks the end of the wire 4 wound around the tooth 50b. The core 50, the rotor shaft 52, and the commutator 53 are arranged coaxially.

  When the core 50 around which the wire 4 is wound by the winding device 200 is applied to a motor (not shown), the current supplied from the commutator 53 is applied to the wire 4 wound around the tooth 50b via the terminal 54. A magnetic force is generated between the flow and the permanent magnets constituting the motor, and the rotor shaft 52 is rotationally driven.

  The winding mechanism 5 supports the rotor shaft 52 and operates an index mechanism 55 that rotates the core 50 about the rotor shaft 52, a flyer 56 to which the nozzle 12 for feeding the wire 4 is attached, and operates the flyer 56. Is provided with a flyer drive mechanism 57 for turning the nozzle 12 around the core 50, and a former 58 for guiding the wire 4 to the slot 50 c of the core 50.

  The index mechanism 55 includes a chuck 60 that grips and supports the rotor shaft 52, a motor 61 that rotates the chuck 60, and a lifting cylinder 64 that drives the lifting platform 62 provided with the chuck 60 up and down along the guide rail 63. Prepare.

The nozzle 12 has a cylindrical shape and is attached to the flyer 56 via a flyer arm 65 in a direction orthogonal to the rotor shaft 52. The wire rod 4 is held by the nozzle 12 through the through hole of the nozzle 12.

  The flyer 56 is supported by a flyer support base 67 via a flyer support shaft 66 and rotates around the flyer support shaft 66. The flyer 56 has a disk shape, and a flyer arm 65 that supports the nozzle 12 is attached to an outer peripheral portion of the flyer 56. As the flyer 56 rotates, the nozzle 12 turns around the core 50, and the wire 4 fed from the nozzle 12 is wound around the teeth 50 b of the core 50.

  The wire 4 supplied from a wire supply source (not shown) is guided to the nozzle 12 through the guide hole 67 a of the flyer support base 67 and the guide hole 56 a of the flyer 56.

  The flyer drive mechanism 57 rotates a flyer support shaft 66 via a belt and a pulley (not shown), and supports a flyer drive motor 68 that rotationally drives the flyer 56 and a flyer support base 67 movably in the axial direction of the shaft 66. A guide rail 69 is provided.

The former 58 is disposed between the core 50 and the flyer 56, and a center former 58a that abuts on the outer peripheral surface of the core 50 to fix the core 50 during winding operation, and a fixing direction of the core 50 by the center former 58a. And a pair of side formers 58b that sandwich and fix the core 50 from both sides in the orthogonal direction.

  The center former 58a and the side former 58b guide the wire 4 toward the slot 50c of the core 50 by guide surfaces formed on the center former 58a and the side former 58b. The center former 58a is connected to the tip of the center former support shaft 70. The flyer support shaft 66 is a hollow shaft, and the center former support shaft 70 is inserted into the hollow portion of the flyer support shaft 66 and supported by a flyer support base 67 so as not to rotate. The side former 58b is arranged so as to be movable on the guide rails 71 and 72, and the relative position with respect to the core 50 can be adjusted.

  Next, the commutator cover removal mechanism 51 will be described. When winding the wire 4 around the teeth 50b, in order to prevent the nozzle 12 from interfering with the commutator 53, the commutator 53 is usually covered with the commutator cover 75 and the wire 4 is used with the commutator cover 75 as a guide. Wind the wire. For this reason, in order to lock the wire 4 to the terminal 54 of the commutator 53 after the end of winding, it is necessary to remove the commutator cover 75 and expose the terminal 54. The commutator cover removing mechanism 51 performs the work of removing the commutator cover 75.

  The commutator cover 75 is a cylindrical cover that covers the commutator 53 and the terminal 54, and an inclined guide surface 75 a that guides the wire 4 fed from the nozzle 12 to the core 50 in a state of covering the commutator 53 and the terminal 54. Have The inclined guide surface 75 a is formed to face the flyer 56.

  The commutator cover removing mechanism 51 includes a commutator cover support portion 76 that supports the commutator cover 75 and a commutator cover moving mechanism 77 that moves the commutator cover support portion.

  The commutator cover moving mechanism 77 includes a front and rear cylinder 78 that moves the commutator cover support portion 76 in the axial direction of the flyer support shaft 66, a support base 79 that supports the front and rear cylinder 78, and a lifting mechanism 30 that lifts and lowers the support base 79. With.

  The elevating mechanism 30 includes a cylinder 31 that is fixed to a column 81 and extends in the vertical direction, an electromagnetic valve 32 that opens and closes in response to a signal from the controller 40, and a piston 33 that reciprocates inside the cylinder 31. A support base 79 is connected to the base plate.

  The cylinder 31 is a double rod cylinder. When compressed air from an air supply source (not shown) is supplied into the cylinder 31 by opening and closing the electromagnetic valve 32, the piston 33 reciprocates. As a result, the commutator cover 75 moves up and down via the support base 79.

  The cylinder 31 includes an origin position sensor 35 as an origin position detector that detects whether or not the commutator cover 75 is at the origin position, that is, whether or not the working position by the commutator cover removal mechanism 51 is at the end position. An operation position sensor 36 is provided as an operation position detector for detecting the current operation position of the commutator cover 75. The origin position sensor 35 outputs a signal when the piston 33 is at the origin position, and the operation position sensor 36 detects the current position of the piston 33.

  A controller 40 is mounted on the winding device 200 and controls the operation of the entire winding device. FIG. 8 is a block diagram showing the configuration of the controller 40.

  As shown in FIG. 8, the controller 40 is configured by connecting a ROM 42, a RAM 43, an origin position sensor 35, and an operation position sensor 36 to a CPU 41 as a center, and a winding mechanism 5 and a commutator cover removal mechanism 51. It controls the operation.

  The ROM 42 stores a control program necessary for the processing operation of the CPU 41 and various setting values.

  The RAM 43 temporarily stores the control program read from the ROM 42 and various set values, and stores information read by the origin position sensor 35 and the operation position sensor 36.

  The controller 40 controls operations of the index mechanism 55, the flyer drive mechanism 57, the former 58, and the like of the winding mechanism 5 by a control program stored in the ROM 42. The operation of the commutator cover moving mechanism 77 of the commutator cover removing mechanism 51 is controlled.

  Next, the operation of the winding device 200 by the controller 40 will be described with reference to FIGS. FIG. 9 is a flowchart showing the operation of the winding device 200, FIG. 10 is a diagram showing the operation of the commutator cover removal mechanism 51, and FIG. 11 is a graph showing the time change of the nozzle speed and the origin position sensor output signal. is there.

  First, the wire 4 from the wire supply source is pulled out of the nozzle 12 through the guide hole 67a of the flyer support base 67 and the guide hole 56a of the flyer 56 through a tension device (not shown), and the end of the wire 4 is clamped. (Not shown).

  The rotor shaft 52 is gripped and supported by the chuck 60 of the index mechanism 55, and the center former 58a and the side former 58b are brought into contact with the outer periphery of the core 50 to fix the core 50. At this time, as shown in FIG. 10, the position of the core 50 is adjusted so that the slot 50c of the core 50 coincides with the gap between the center former 58a and the side former 58b. Further, the commutator cover moving mechanism 77 is driven to lower the commutator cover 75, and the commutator 53 and the terminal 54 are covered with the commutator cover 75.

  The flyer 56 is rotated by driving the flyer driving mechanism 57. Thereby, the nozzle 12 turns around the core 50, and the wire 4 is wound around the teeth 50b of the core 50 as shown in FIG. 10A (step 1 in FIG. 9). At this time, the wire 4 is guided to the inclined guide surface 75a of the commutator cover 75 and the former 58 and wound around the teeth 50b.

  After winding the wire 4 around the teeth 50b, the commutator cover moving mechanism 77 is driven in order to lock the wire 4 to the terminal 54 of the commutator 53, and as shown in FIG. 75 is removed to expose the terminal 54 (step 2 in FIG. 9). Specifically, by the operation of the electromagnetic valve 32 of the elevating mechanism 30, air is supplied into the cylinder 31, the piston 33 inside the cylinder rises, and the commutator cover 75 supported by the commutator cover support portion 76 is removed. . The timing for driving the commutator cover moving mechanism 77 and starting the removal of the commutator cover 75 is preferably immediately after the nozzle 12 enters the last round.

  In step 2 above, when the nozzle 12 is turning around the core 50, for example, when the nozzle 12 in the last round is positioned below the core 50 as shown in FIG. In addition, it is confirmed whether or not the work for removing the commutator cover 75 by the commutator cover removal mechanism 51 has been completed. Specifically, it is confirmed by the origin position sensor 35 whether or not the commutator cover 75 is at the origin position (step 3 in FIG. 9). When the position of the piston 33 is at the uppermost position (origin position) in the cylinder 31, the origin position sensor 35 outputs a signal, and it is confirmed that the commutator cover 75 is at the origin position. As described above, in Step 3, it is determined whether or not the commutator cover removal mechanism 51 is at the origin position while the nozzle 12 is turning around the core 50, that is, during the winding operation.

  In step 3, when the origin position sensor 35 detects that the commutator cover 75 has reached the origin position, that is, when the commutator cover removal mechanism 51 determines that the commutator cover 75 has been removed. Since the terminal 54 of the commutator 53 is exposed, the nozzle 12 locks the wire 4 to the terminal 54 without stopping (step 4 in FIG. 9).

  FIG. 11 shows temporal changes in the nozzle speed and the origin position sensor output signal at this time. The solid line in the figure indicates the speed of the nozzle 12, and the dotted line indicates the output signal of the origin position sensor 35. When the commutator cover 75 is at the origin position, the output signal of the origin position sensor 35 is ON. After the nozzle 12 enters the last round, the commutator cover 75 is removed by the commutator cover removal mechanism 51. Then, at a predetermined timing (t in the figure), it is confirmed by the origin position sensor 35 whether or not the commutator cover 75 is at the origin position. At this time, when the output signal of the origin position sensor 35 is ON as shown in FIG. 11, the nozzle 12 continues the operation of locking the wire 4 to the terminal 54 of the commutator 53 without stopping.

  Further, in step 3, when the origin position sensor 35 cannot detect the arrival of the commutator cover 75 to the origin position, that is, it is determined that the commutator cover removal mechanism 51 has not finished removing the commutator cover 75. In this case, the nozzle 12 stops once just before locking the wire to the terminal 54 (step 5 in FIG. 9). Then, returning to step 3 again, the origin position sensor 35 detects that the commutator cover 75 has reached the origin position, and then proceeds to step 4 where the wire 4 is locked to the terminal 54.

  After step 4, the process returns to step 1 to operate the index mechanism 55 to rotate the core 50 around the rotor shaft 52 and wind the wire 4 around the other tooth 50b. Thus, the above operation is performed by forming a loop, and the wire 4 is wound around all the teeth 50 b of the core 50.

  The timing at which the commutator cover 75 is removed and the timing at which the origin position sensor 35 checks whether the commutator cover 75 is at the origin position are arbitrarily set by a program stored in the ROM 42. be able to.

  Further, if the current position of the commutator cover 75 is continuously detected by constantly detecting the current position of the piston 33 by the operation position sensor 36, the terminal 54 of the commutator 53 is exposed when the current position is exposed. It can also be determined that the removal of the commutator cover 75 by the commutator cover removal mechanism 51 has been completed. By comprising in this way, the transfer to the operation of locking the wire 4 to the terminal 54 can be performed more smoothly.

  According to the winding device 200 according to the second embodiment of the present invention described above, when the removal of the commutator cover 75 is completed, the transition from the winding operation of the nozzle 12 to the locking operation of the wire 4 is performed. Is continuously performed without stopping, so that the winding work can be performed efficiently.

  Further, when the commutator cover 75 has not been removed, the operation of the nozzle 12 is temporarily stopped, but the operation of the nozzle 12 is resumed as soon as the commutator cover 75 has been removed. Therefore, the winding operation can be performed more efficiently than when a predetermined time is set between the winding operation of the nozzle 12 and the operation of the commutator cover removal mechanism 51. The work time can be shortened.

  The present invention is not limited to the above-described embodiment, and it is obvious that various modifications can be made within the scope of the technical idea.

  The present invention can be applied to a manufacturing apparatus of a multilayer coil and a stator core of a motor.
