The conventional winding device moves the rotary motor 3, which rotates the bobbin 2, and the guide 4 to the left and right as shown in FIG. 1 and FIG. Servo motor 5, which allows the thread to be wound in a predetermined pattern, sensors 7 and 8 provided with the maximum width of the bobbin 2 under the screw 6 of the servo motor 5, and the sensor 7 ( 8) a stepping motor 9 for moving the motor, an inverter 10 for the rotary motor 3, a servo motor driver 11, a stepping moto driver 12, a relay sequence circuit and a power supply 13 It is composed of a control unit 14 included.

Looking at the operation of the conventional winding device configured as described above are as follows.

That is, the real position guide 4 is moved left and right by the screw 6 by the forward and reverse drive of the servomotor 5.

In addition, when the servomotor 5 drives to the left side and receives a signal from the sensor 8 in the direction, the servomotor 5 drives to the right side again.

In this way, when the reciprocating operation of the guide 4 is completed in response to the signals of the left and right sensors 7 and 8, the position of the sensors 7 and 8 is shifted inward by a stepping motor 9.

The panel 18 is comprised.

According to the present invention configured as described above, the servomotor 5 is driven by the numerical control system 17 in the standby state to position the winding guide guide 4 to each starting point S of FIG. 5, and then the operation panel 18. The start switch is turned on by selecting one pattern from FIGS. 5A to 5D and inputting data values of each program accordingly.

Thus, the rotary motor 3 is rotated by analog control at a programmed speed from the numerical control system 17 and winds up the thread.

At this time, the numerical control system 17 checks the pulse amount generated while the first encoder 15 installed on the bobbin 2 side rotates with the bobbin 2, and according to the data value of the input program, The servomotor 5 is rotated forward and backward at a ratio so that the winding guide guide 4 is operated left and right to wind the thread in various patterns as shown in FIG.

At this time, the important thing when winding the yarn should be wound while unwinding from the yarn (1) at a constant speed in the present invention in order to maintain a constant speed of the yarn in order to maintain a constant speed of the second encoder for recognition per hour (16) ), The number of pulses of the second encoder 16 generated per unit time is recognized by the numerical control system 17, and closed-loop control (feedback control of the motor 3 due to an accident) is performed to rotate the motor 3. By adjusting the speed of), the yarn (1) is released from the beginning to the end at a constant speed.

Hereinafter, a program method for each pattern will be described with reference to FIGS. 5 and 6 to 9.

5a and 6 are a sagittal winding method of an embodiment of the present invention, the program is made of S_, E_, D_, I_, Q_, C_, Z_, M_.

Where _ is the position to put the appropriate day value, S is the starting point coordinate, E is the end point coordinate, D is the width at completion, I is the width of winding change in one round trip, and Q is the S to E point. The total number of pulses generated by one encoder 15, C is the number of pulses of the first encoder 15 changed during one round trip, Z is the speed of the first encoder 15, and M is the length of the yarn to be totally wound.

That is, as shown in FIG. 6, the initial data S, E, D, I, Q, C, Z, and M are input (S ₁ ), and the rotation motor 3 is moved from the speed of the second encoder 16 ( Rotate in synchronization with Z) (S ₂ ).

Then, after the bobbin rotation per distance from the winding point S to the winding end point E, the servomotor 5 driving the winding guide 4 is counted while counting the number of output pulses from the first encoder 15. rotating the motor 3 in synchronism with the rotation then transported toward the winding end point (E), the winding guide a guide 4 to the winding point (S) side (S _3).

At this time, the current actual position value is calculated based on the number of output pulses of the first encoder 15. If the calculated present actual position value is smaller than the winding end point (Z) coordinate value, the transfer step S ₃ is continued, and if the calculated current actual position is greater than or equal to the winding end point (E) coordinate value, S) Subtract the winding change width (1) at the time of one round trip to the coordinate value, and at the number of output pulses (Q) from the first encoder (15) of the bobbin axis of rotation during the travel time from the winding point (S) to the winding end point.

Then, the servomotor 5 is rotated in reverse in synchronization with the rotary motor 3 to transfer the winding guide guide 4 from the winding end point E side to the winding start point S side (S ₅ ).

Then, the number of pillars output from the second encoder 16 is counted to calculate the length of the currently wound yarn, and the winding length M to be wound is compared (S ₇ ).

In comparison, if the current winding length is greater than or equal to the total winding length (M) of winding, the rotation motor (3) and the servomotor (5) are stopped to finish winding, and the total winding length of the current winding length is winding. The number of output pulses from the first encoder 15 of the bobbin rotation shaft is counted from M), and the current actual position value is compared with the current thread position value by the winding point S side coordinate S-1 (S ₈ ). If it is smaller than the winding start point (S) side, it continues to drive the rotation motor (3) and the servo motor (5), and if the current actual position value is the same as the winding start point (S) side coordinate value (SI), the winding end point (E) coordinate At the time of one round trip from the value, the winding increase and decrease width (1) is subtracted, and at the time of one round trip at the number of output pulses (Q) from the first encoder of the bobbin rotary shaft generated during the movement time from the winding point to the winding end point. by subtracting the number of output pulses is changed (C) and then (S _9), the winding guide a guide (4) the volume in the winding point (S) side End point (E) in synchronization with the rotation motor (3) to be transported toward rotates the servo motor 5 constant.

In this way, the servomotor 5 is repeatedly rotated forward and backward to finish winding when the length of the wound yarn and the total length of the winding yarn are the same.

Here, the winding change width (I) is subtracted from the winding point (S) coordinate value once and the winding change width (I) is added to the winding end point (E) coordinate value once. It becomes a pattern.

5b and 7 are trapezoidal repetitive patterns and operation flowcharts of the second embodiment of the present invention. As shown in Fig. 5b, the programs are made of S_, E_, D_, I_, K_, Q_, C_, Z_, M_, Pn_, .

Here, K denotes the number of round trips in each pattern P ₁ -P _n , P _n denotes the number of patterns, and the rest is the same as that of the first embodiment of the present invention.

Then, the servomotor 5 which drives the winding guide guide 4 while counting the number of output pulses from the bobbin rotary shaft first encoder 15 per distance from the winding point S to the winding end bottom E is measured. It rotates synchronously with the rotating motor 3, and transfers the guide 4 for winding guidance from the winding scissor S side to the winding end point E side ( _S13 ).

At this time, the actual position value of the ubiquity is calculated based on the number of output pulses of the first encoder 15 (S ₁₄ ).

If the calculated current actual position value is smaller than the winding end point (E) coordinate value, the transfer step S ₁₃ is continued, and the calculated current actual position value is one round trip to the winding end point E. ) Is subtracted from the number of output pulses (Q) from the first encoder (15), and the number of output pulses (C) changed during one round-trip winding is subtracted (S ₁₃ ), and the number of patterns (T _p ) is even. In the case of one round trip, the winding change width (I) is subtracted from the winding point coordinate value (S), and the number of output pulses C is increased or decreased during round trip once from the number of output pulses (Q _p ) from the first encoder (15). ) Is added (S ₁₆ ).

In comparison, if the current winding length is greater than or equal to the total winding length (M) of winding winding, the rotating motor (3) and the servomotor (5) are stopped to finish winding (S ₁₉ ), and the winding winding current winding length is winding. If it is smaller than the length M, the current actual position value is detected and conveyed until the winding time coordinate value S = S + I set in S ₁₅ is reached (S ₂₀ ).

When the winding time coordinate value is reached, if the number of patterns is odd according to the pattern number T _p , the winding change width I is subtracted from the winding torque coordinate value E for one round trip and the output pulse from the first encoder 15 is subtracted. Subtract the output pulse number C that changes during one round trip to the number Q (S ₁₂ ), and if the pattern number T _p is even, the winding change width for one round trip to the winding end point coordinate value E (I) is added (E = E + I) and the number of pulses C changed at the time of winding round trip to the number of output pulses Q is added (Q = Q + C) (S ₂₂ ).

Then, by increasing the number of round trips (K) by one (K = K + 1) (S ₂₃ ), and winding the servomotor forward and backward until the number of round trips (K) becomes a constant value (X), the number of round trips ( When K) becomes a constant value (X), the number of patterns (T _p ) is increased by one (T _p +1) (S ₂₄ ). When the number of patterns is odd, it is wound in an upright trapezoidal shape, and when the number of patterns is even, an inverted trapezoidal shape is formed. Recommended (and vice versa).

At this time, the current actual position value is calculated based on the number of output pulses of the first encoder 15 (S ₃₄ ).

If the calculated actual actual position value is smaller than the winding end point (E) coordinate value, the transfer step S ₃₃ is continued, and if the calculated current actual position value is smaller than the winding end point E coordinate value, the transfer step ( S ₃₃ ), and if the calculated current actual position value is greater than or equal to the winding end point (E) coordinate value, the change width (1) for one round trip is added to the winding time (S) coordinate value (S ₃₅ ), The servomotor 5 is rotated in reverse in synchronization with the rotary motor 3 to move the winding guide 4 in the reverse direction from the winding end point E to the winding start point S (S ₃₆ ).

In this case as well, the current actual position value is calculated from the number of output pulses of the first encoder 15, and the actual position value is transferred until the winding position (E) coordinate value is obtained (S ₃₇ ). The winding change width 1 is added to the value once (S ₃₆ ) and the above (S _{38 to} S ₃₇ ) process is repeated.

The servo motor is rotated forward and backward until the total length of winding winding is compared with the total length (M) of calculating and winding the current length by the number of output pulses of the second encoder 16, and winding and present When the length of the yarn is longer than the length of the winding nose, the motor is stopped and winding is terminated (S ₃₉ ).

Here, even when S = S-I and E = E-I carry out reverse transfer and conveyance of the guide 4 for winding guidance, it becomes a parallelogram winding pattern.

The rotary motor 3 is rotated in synchronization with the speed of the second encoder 16 (S ₄₂ ).

Then, the winding guidance guide 4 is wound on the winding start point S while counting the number of output pulses of the bobbin rotary shaft first encoder 15 per distance from the winding start point S to the winding end point E. (S ₄₃ ).

When the thread position reaches the winding end point (E) coordinate value, depending on the number of patterns (P _n ), if the number of patterns (P _n ) is odd, the winding change width (I) for one round trip to the winding starting point (S) coordinate value Subtract it (S ₄₅ ).

Then, the servomotor 5 is rotated in reverse in synchronization with the rotation motor 3 so as to transfer the winding guide 4 from the winding end point E to the winding start point S in the reverse direction (S ₄₆ ).

At this time, the actual position value is calculated from the first encoder 15 and transferred until the winding time coordinate value S + I is obtained (S ₄₇ ). If the pattern number P _n is odd, the winding end point ( E) The winding change width (I) is added to the coordinate value once round trip (S ₄₈ ). If the number of patterns (P _n ) is even, the winding change width (I) is subtracted from the winding end point (E) coordinate value once. (S ₄₉ ).

Then, the number of round trips (K) is increased by 1 (S ₅₀ ) and the round trip is repeated until the number of round trips is a constant value, and when the number of round trips is a constant value, the pattern number (P _n ) is increased by 1 (S ₅₉ ) Initialize (K = 0) and repeat the above steps (S _{43 to} S ₅₁ ) to stop the motor and terminate winding when the length of the currently wound yarn becomes more than the length of the wound winding yarn (S _52). )

Here, it is also possible to change the odd number of the pattern number P _n . As described above, in the winding device and the winding control method using the numerical control system of the present invention, by using the numerical control system without using the conventional sensor and relay circuit, the system is simplified and the failure rate is reduced.
