[0013]
Further, a shaft 36, which is supported by a shaft 36A, is attached to the frame 31 so as to pass through the center of the first spatula support member 11, and the winding jig 1 is integrally attached to an end of the shaft 36. I have. A gear 38 is connected to the opposite end of the shaft 36 via a gear 37, the shaft 22 is fixed to the gear 38, and the gear 38 is fixed to an output shaft of a motor 39. And these gears 37, 38, and 40 constitute a known differential gear mechanism. The motor 39 is electrically connected to the DC motor 31 via a controller which will be described later. Every time the DC motor 31 rotates the spatula once, the motor 39 rotates according to a signal from the controller, and The action of the dynamic gear mechanism advances the winding jig 1 by the thickness of the wire W. The motor 39, the controller, and the differential gear mechanism constitute electrical control means for setting the advance angle of the winding jig.
[0014]
The configuration of the controller 50 that controls the motor will be described with reference to FIG.
In the figure, a DC motor 31 is connected to a power source (not shown) via a switch 44. The DC motor 31 is connected to an encoder 41 via pulleys and gears as shown in FIG. Are mechanically connected via a differential gear 38.

I do. The motor 39 drives the gear 40, the differential gear 38, and the gear 37 in response to the advance pulse, and the operation of the differential gear 38 causes the wire W to be wound every time the winding jig rotates once. The angle is advanced with respect to the rotation of the spatula by the diameter, and control is performed so that the wire W is not overlapped and wound on the winding jig (this operation will be described later). Further, the second ratio divider 47 generates a traverse drive pulse based on the reference pulse, outputs the traverse drive pulse to a motor (not shown) for reciprocating the nozzle 4, and controls the reciprocation of the nozzle 4.
[0015]
As described above, the DC motor 31 for rotating the spatula and the motor 39 for advancing the winding jig 1 are electrically controlled by the controller 50, and the differential gear 38 is incorporated between both output shafts. It is not necessary to use a complicated gear transmission mechanism for setting the advance angle as in the conventional case, it is possible to easily synchronize the rotation of the winding jig and the spatula, and wind the wire W without overlapping the winding jig. It is possible to wind it up on a jig.
In this cup-type coil winding machine, a wire W is wound on a winding jig as follows to manufacture a coil.
[0016]
Referring to FIGS. 1 and 5 to 9, first, the wire W is pulled out from the nozzle 4, and is fixed to the wire fixing pin 15 through the inside of the first spatula 2. At this time, the first spatula 2 and the second spatula 3 are at the upper and lower positions shown at the start position 0 ° shown in FIG. From this state, the nozzle 4 is moved to the left in the drawing while simultaneously rotating the winding jig 1 and the first and second spats 2 and 3 in the directions of the arrows shown in the drawing. When the first and second spats 2 and 3 and the winding jig 1 are rotated by 90 °, the first and second spats 2 and 3 are moved to the horizontal position as shown in FIG. The wire W is moved to the half position, and the wire W is wound around the winding jig 1 周. Further, when the first and second spats 2 and 3 and the winding jig 1 are rotated by 180 °, the left and right positions and the up and down positions of the first and second spats 2 and 3 are switched as shown in FIG. The wire W is moved to the position, and the wire W is wound around the winding jig by a half turn. Further, when the winding jig 1 and the first and second spats 2 and 3 are continuously rotated in the same direction, the nozzle 4 starts to move rightward in the drawing, and the wire is caught outside the second spatula and turned back. When rotated by 270 °, the first and second spatulaes 2 and 3 move to the horizontal position again as shown in FIG. 8, and the wire W is wound around the winding jig by ／ turn. When the winding jig 1 and the first and second spats 2 and 3 are rotated by 360 °, the winding jig is returned to the turning point of the initial position as shown in FIG. Starts moving to the left in the figure, and performs the same winding operation as described above.
[0017]
Then, the wire W that has returned to the initial position for the second time repeats the same operation as described above, but if the number of rotations of the winding jig and the first spatula and the second spatula are the same, the second turn is performed. Sometimes, the second wire W overlaps and is wound on the first wire W. For this reason, after the first wire W is wound, when the second wire W comes, the winding jig needs to advance (advance) with respect to the rotation number of the spatula by the thickness of the wire W. There is. For this reason, between the winding jig and the first and second spatula, a mechanism for advancing the winding jig every one rotation is required. The tip of the spatula is formed with a predetermined gap toward the coil so that the wire W on the spatula easily moves onto the winding jig 1 by the action of the next wire W.
[0018]
The advance of the winding jig 1 at the time of winding the wire W is performed as follows.
In FIG. 4, a reference pulse is generated by a quadruple circuit 45 based on the rotation speed of the DC motor 31 detected by the encoder 41, and the reference pulse is set by a data setter 48 via a first ratio divider 46. The pulse is converted to an advanced pulse and output to the motor 39. The motor 39 drives the differential gear 38 via the gear 40 based on the advance pulse (see FIG. 3). Each time the winding jig 1 and each spatula make one rotation by the action of the differential gear 38, the winding jig 1 is advanced by the wire diameter of the wire W to be wound with respect to one rotation of the spatula, and the wire W It does not overlap and is wound on the winding jig. The advance angle can be freely set by the data setting device 48 in accordance with the thickness of the wire W.
[0019]
Next, in the process of manufacturing the coil, it is necessary to form a coil by the number of motor commutator pieces, and this tap forming method will be described with reference to FIGS.
When a predetermined amount of winding is wound on the winding jig 1 by the above-described operation (for example, in the case of three commutator pieces, when 1/3 winding work is completed), the winding jig 1, the spatula 2,. 3. The driving of the nozzle 4 is temporarily stopped. In this state, as shown in FIG. 11, the twist hook 7 is advanced, the wire W is hooked on the hook 7a, the twist hook 7 is rotated by operating the motor 8, and the wire W is twisted to form a tap T. At this time, in the conventional tap manufacturing method, a hook is hooked between the nozzle and the coil end, and in this state, the twist hook 7 is rotated to twist the wire W, so that the tap portion is as shown in FIG. An uneven twist state results. After the coil is completed, the end of the tap made of such non-uniform twist is cut off by the nipper, and the twisted part will be unraveled. This causes inconvenience in the work and causes a product failure.
[0020]
For this reason, in the present apparatus, when forming the tap T, the wire W which has been fed from the nozzle 4 as shown in FIG. 12 is pressed by the wire presser 5 advanced by the driving means 6 (see FIG. 1). In this state, twisting is performed with the twist hook 7. Both wires are started to be twisted from the hook 7a side in a state of approaching. As a result, as shown in FIG. 10 (b), a tap T that is evenly twisted up to the root is formed, and the evenly twisted tap T cannot be unwound even if the end is cut by the nipper. Thereafter, winding of the wire W on the winding jig starts again. At this time, if the tap T is not wound evenly, the slack will affect and increase the turbulence. However, this is prevented, and when the winding of 2/3 of the coil is completed, the second tap is formed. Similarly, the third tap is formed, and the manufacture of the coil is completed. The number of taps to be formed on the coil is formed in accordance with the number of commutator pieces of the motor used by the above-described operation. When manufacturing the tap, hot air is blown toward the tap to temporarily fix the tap, and the hot air is blown at the same timing as in the related art.
As described above, the wire W is wound on the winding jig, and when the wire W has a predetermined shape, a completed coil is formed and removed from the winding jig.
[0021]
Next, a second embodiment of the present invention will be described with reference to FIGS.

In the figure, reference numeral 51 denotes a driving means (pulse motor in this example) for rotating the first and second spatula, 52 denotes a driving means (pulse motor in this example) for rotating the winding jig 1, and 53 reciprocates the nozzle 4. (In this example, a pulse motor), and these drive units are connected to a controller to be described later, and constitute an electric control unit. The winding jig 1 is integrally mounted on the output shaft of the winding jig motor 52. When the winding jig motor 52 rotates, the winding jig 1 also rotates. When the motor 51 for the spatula rotates, the shaft 54 rotates, and the first spatula 2 rotates via the first belt transmission means (pulley, transmission belt) 55. Further, the second spatula 3 is synchronously rotated via a second belt transmission means (pulley, transmission belt) 56 which is coaxial. When the motor 53 for reciprocating the nozzle 4 further rotates, the nozzle reciprocates along the winding jig 1.
[0022]
The controller 61 includes a data setter 58, a rotation pulse generator 57, and multipliers 59 and 60, as shown in FIG. 14, and is controlled by a motor 51 which operates based on the pulse generated from the rotation pulse generator 57. Actuate shaft 54. Further, a predetermined coefficient is multiplied by the multiplier 59 based on the pulse generated from the rotation pulse generator 57, and the output thereof operates the winding jig rotation motor 52. Further, a predetermined coefficient is multiplied by the multiplier 60 based on the pulse generated from the rotation pulse generator 57, and the output thereof activates the motor 53 for nozzle traverse.
The coefficients of the multipliers 59 and 60 can be arbitrarily changed by a data setting device.
[0023]
In the second embodiment, the motors 51, 52, and 53 are controlled by output signals from the controller 61, and the winding jig 1, the spatula 2, 3, and the nozzle 4 operate independently. At this time, similarly to the first embodiment described above, the winding jig 1 is advanced by the wire diameter of the wire W to be wound, and the winding jig is prevented from overlapping and being wound on the winding jig. The rotation speed of the tool and the spatula is controlled. The advance angle can be freely set by the data setting device 48 in accordance with the thickness of the wire W. The necessary number of taps is formed in the same manner as in the first embodiment. The operation of winding the wire W around the winding jig 1 is the same as in FIGS. 5 to 9, and the description thereof will be omitted because it is redundant.
[0024]
