Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pulse motor drive system in a cup rotor winding device used in a coreless motor.

As shown in FIG. 1, the winding body 1 of the cup rotor has a winding frame 2.
1 of the commutator by winding the coil wire 3 at 180 degrees opposite position.
One-phase coils 4 corresponding to the segments are formed, terminals 5 for connecting to the segments are drawn out, and m-phase phase coils are sequentially formed in an annular shape around the winding frame 2.

This winding body 1 is made by a winding device shown in FIG.

That is, the winding frame 2 is connected to the rotating shaft of a pulse motor 7 via a collet chuck 6, and the shuttle 8, which is rotated by another motor in an inclined state with respect to the winding frame 2, is connected to a coil wire 3.
A bobbin 9 is attached, and the coil wire S is connected to the pulley 1.
0 to the winding frame 2. In this winding device, a pulse motor 7 rotates the coil wire 3 in response to the rotation of the shuttle 8 and winds the coil wire 3 sequentially onto the winding frame 2, thereby forming the winding body 1. In addition, the coil wire 3 is connected to the guide strips 11 and 12 provided on the winding frame 2.
The saw is bent at the desired angle. Therefore, reel frame 2 is shuttle 8
The winding body 1 takes a step each time it rotates, and the timing is
The number of phases, that is, the number of commutator segments m, the number of turns per one phase n, and the number of divisions of one rotation of the pulse motor 7 can be determined. That is, as shown in FIG. 3, X pulses P2 are generated in accordance with the rotational pulse P, which is obtained one rotation of the shuttle 8, and Y pulses among them are used to drive the pulse motor 7. If it were to move in steps, it would be Tamagoto-san.

Here, to simplify the circuit, the number of pulses Y is the number of turns n
If it matches, then so=m・X. Therefore, if x number of pulses is set to x=so/m, the pulse motor can be advanced by one step with Y=n pulses. Like this
1 to advance the pulse motor by one step using pulses of
This is the first clock pulse P4 for pitch feeding shown in FIG. 6. The lead terminal 5 is connected to a pair of pins 13 provided on the winding frame 2 as shown in FIG.
The coil wire 3 supplied from the shuttle 8 is attached to the hook 1.
4 and rotate the hook 14 to form a hook.

However, even when hooking the coil wire 3 to the pins 13, 13, when the pulse motor 7 is rotated at a constant pitch, the hook 14 on which the coil wire 3 is hooked rotates. The front part (winding frame fixed side) and the rear part (bobbin 9 side) of the coil wire 3 are rubbed, and the coil wire 3 is separated from the guide strip 11, and the front part when the hook is towed is rubbed by the pulse motor 7. It moves to the rotating side, that is, the already wound coil wire side. In addition, since the guide strips 11 on the line of the A part and the line of the C part of the coil wire 3 are spaced apart from the winding frame,
The coil wire 3 supplied from the shuttle 8 enters between the winding frame 2 and the guide string 11 and enters under the coil wire already wound around the winding frame 2, that is, the guide string 11. Also, when the coil wire 3 is folded back at the guide strip 11, the coil wire slides using the guide strip 11 as a guide and reaches a predetermined position.
When the guide string 11 has poor slippage, the coil wire may accumulate on the guide strip without reaching a predetermined position.
In this case, when the coil wire 3 moves from the opening to C and is further wound around the winding frame 2 when the terminal is taken out, the coil wire from the pin 13 may overlap the already wound coil winding portion.
In this way, an overlap occurs when the terminals are brought out, and pressure is applied to this overlap when shaping the rotor winding body 1, resulting in defects such as short circuits. The present invention was devised in view of the above points, and a pulse motor for advancing the winding frame is driven in fast forward motion when the terminal is taken out during the winding of the last nth turn of each phase, so that the overlapping occurs as shown in FIG. This is to prevent this from occurring.

An embodiment of the present invention will be described based on FIGS. 6 and 7.

Figure 6 shows the time chart, P3 is the last one of each phase.
This is a turn timing signal, and during this signal period, the terminal hook 14 is sent out and rotated, and the pin 13,
Hook the coil wire 3 to 13. P4 is the aforementioned first clock pulse, which is output at approximately equal intervals if the rotational speed of the shuttle 8 is the same. This clock pulse P4
Since the pulse motor is advanced by one step, the winding frame 2 is advanced by (m·n) steps per turn. P5 is the clock pulse P4 minus Z clock pulses near the leading edge of the timing signal P3. P6
are Z second clock pulses with a faster period to replace the Z removed clock pulses, and P7 is the pulse P5.
This is a pitch feed clock pulse in which P6 and P6 are superimposed.
Therefore, when winding from the 1st turn to the (n-1)th turn of each phase, the pulse motor is driven with the pulse P5 so that the winding frame 2 is advanced by 〆/(m・n) steps per turn. do.

Also, when outputting the terminal at the last nth turn of each phase, the pulse motor is fast-forwarded by the second clock pulse p6,
As mentioned above, the coil wire 3 is connected to the pin 13 by the hook 14.
, 13 and perform the terminal extraction work. Next pulse P7
is generated by the pulse generating circuit shown in FIG.

This generating circuit operates a monostable multipipulator M on the green side of the timing signal P3, and sets an R.S flip-flop F, with its output. Q of this flip-flop
The output of the AND circuit A, which receives the output and the inverse pulse P4 of the first clock pulse P4, is input to the counter C. Now if Z = 3, the output of the AND circuit A2 which inputs Mebit A and bit B is input to IJ of flip-flop F.
Set signal. Further, the output of the AND circuit A3, which receives the Q output of the flip-flop F and the inverse pulse P4 as input, becomes the pulse P5. Further, the output of the oscillator OS, which has a higher frequency than the first clock pulse P4, is input to the counter C2 via the AND gate A4, and when the dibit A and the common bit B of this counter are input, the output of the AND circuit A5E is input to the inverter 1, Invert it and put it into the AND gate and close this gate. As a result, the AN
The output of the D circuit A6 becomes the inverse pulse P6 of the second clock pulse P3, and this inverse pulse is inverted by the inverter 12' and is ORed with the output P5 of the AND circuit.
A reverse pulse P7 of the pulse P7 is formed in the circuit ○. In the above embodiment, from the first turn of each phase
1) When winding a turn, the advance of the winding frame 2 per turn is 1/(m・n), so taking into consideration Z second clock pulses P6, this Since pulses P5 other than Z must be generated, the pulse generation circuit becomes complicated.

Therefore, in the second embodiment, when Z pulses are used for each phase for terminal output, the number of pulses per evening is The advancing step of the winding frame 2 can be set to (coum・Z)/(m・n), and in this case, the first step as in the first embodiment is
There is no need to create a pulse P5 by removing Z pulses from the clock pulse P4, and the pulse generation circuit becomes simpler.
A time chart of the second embodiment thus constructed is shown in FIG. P8 is the first clock pulse corresponding to pulse P4, and one pulse is generated by Y pulses out of X pulses P2, and the pulse interval is larger than that of pulse P4. P9 is a second clock pulse produced Z times by the leading edge of the timing signal P3, and its period is shorter than that of the first clock pulse P8. P, o are pulses obtained by combining the first and second clock pulses P8, P9, and when winding from the first turn to the younger (n-1) turn of each phase, the first clock of these pulses P, o is used. Pulse P
The pulse motor is driven by a pulse corresponding to No. 8, and the winding frame 2 is advanced by (Y-mZ)/(m.n) steps per turn. In addition, when outputting the terminal in the n-th turn, the pulse motor is fast-forwarded by Z second clock pulses P9 and one or two first clock pulses P8, and then the hook 1
4, the coil wire 3 is latched onto the pins 13, 13, and as shown in FIG. 5, the coil wire 3 is aligned with the already wound coil wire, and the terminal is brought out. The pulses P and o are generated by a pulse generating circuit shown in FIG. That is, the output of the oscillator OS2 is AN
It becomes an input to the counter C3 via the D gate A7, and when counting Z pulses (four in the embodiment), the output of the counter C3 closes the AND gate A7. Therefore, the number of oscillator output pulses passing through this pulse is Z, which becomes one input of the AND circuit A8, and the inverse signal P3 of the timing signal P3 becomes the other input via the inverter, and the output of the AND circuit A8 becomes the This becomes the reverse pulse P9 of the two-clock pulse P9. This reverse pulse P9 and the first
The inverse pulse P8 of the clock pulse P8 becomes an input to the OR circuit 02, which outputs the summed pulses P and o. In the above embodiment, the winding frame 2 is fast-forwarded by a predetermined angle when taking out the terminal, but after the n-th turn of the terminal taking out, the first
In order to align the turn with the n-th turn, it is necessary to select the number Z of fast-forward pulses as the predetermined angle.

Therefore, it is desirable to fast-forward the winding frame by more than the predetermined angle at the beginning of the terminal-out operation, and to move the winding frame backward by the amount of fast-forwarding at the end of the terminal-out operation. An embodiment invented in view of this point will be described with reference to FIGS. 10 to 12. Figure 10 shows the time chart, and P

The signals P and 4 generate Z' second clock pulses P and 5 for fast forwarding and reversing, respectively. In addition, the first clock pulse P4 mentioned above
, P8 to obtain the first clock pulse P, 6 for pitch feeding which advances the pulse motor 7, and create a superimposed pulse P, 7 of both clock pulses P, 5, P, 6. When winding the first turn to the (n-1)th turn of each phase of the coil wire 3, the winding frame 2 is advanced in equally spaced steps by the first clock pulses P and 6. On the other hand, when outputting the terminal of the last n-th turn of each phase, Z'
The winding frame 2 is fast-forwarded by the fast-forwarding pulses P and 8, and at the same time, the timing pulse P. 2, the hook 14 is sent out and the coil wire 3 is hooked on the hook 14, and then the hook 14 is rotated by the timing pulses P, 3, and the hooked coil wire 3 is hooked on the pins 13, 13. In this case, the coil wire 3 hooked on the hook 14 is removed from the hook 14 by further rotating the hook 14. At the end of terminal output, the winding frame 2 is returned to a predetermined position by Z' number of reverse pulses P, 9. The superimposed pulse 17 is generated by a pulse generating circuit shown in FIG. That is, oscillator OS3
The oscillation pulse from the counter C4 enters the counter C4 via the AND gate A9, and when a predetermined number of Z' (Z=3 in the embodiment) is counted, the output of the counter C4 is sent to the AND circuit A. Since the AND gate A9 is closed via the inverter 14 and the inverter 14, the number of pulses passing through the AND gate A9 becomes Z'. This counter C4 receives timing pulses P, 2 and reversal signal P.
, 4 is reset by the output of the OR circuit 03, which receives the timing pulse P, 2 and the reversal signal P, 4.
Z' pulses are passed through the AND gate in response to the respective values.
AND circuits A, .
The output of is the inverse pulse P,5 of the second clock pulse P,5
becomes. Moreover, this reverse pulse P,5 and the first clock pulse P. The output of the OR circuit 04 which receives the inverse pulse P, 6 of 6 becomes the superimposed pulse P, 7. In this embodiment, the reverse pulse P. Although 9 is made the same number as the fast forward pulse P,8, the number of reverse pulses P,9 may be smaller than the fast forward pulse P,8. Further, the drive circuit for the pulse motor 7, which rotates in the forward and backward directions by the superimposed pulses P and 7, is constructed as shown in FIG.

That is, a pair of exclusive OR circuits E, E2 each having one input of the reversal signals P, 4 is provided, and the output of each circuit and the output via the inverters 16, 17 are used as J and K inputs, A circuit E.J.K flip-flops F2 and F3 having superimposed pulses P and 7 as T inputs are connected to the circuit E. , E2, and the Q output of one flip-flop F2 is used as the other input of the circuit E2, and the Q output of the other flip-flop F3 is used as the other input of the circuit E. Each flip-flop F2,
The output of F3 is applied to the bases of control transistors T, -L, respectively, and the four-phase stator coils 1 - W of the pulse motor are energized and controlled by switch transistors T5 - T8 whose bases are connected to the collectors of these control transistors.
In the figure, V^ and V8 are power supply voltages. As described above, according to the present invention, the winding frame on which the coil wire is wound is fast-forwarded when the terminal is brought out in winding the last turn of the coil wire of each phase, so that the turn of the terminal is already wound. There is no overlap with the coil winding portion wound on the frame, and it is possible to perform aligned winding.

In addition, in a method in which the winding frame is fast-forwarded at the start of terminal output and then returned to a predetermined position at the end of terminal output, compared to the case where the winding frame is not reversed, the fast-forward pulse is faster when winding in alignment with the next phase. There is no need to accurately select the number of fast-forwarding pulses, and the number of fast-forwarding pulses only needs to be a predetermined number or more, which simplifies the selection.
