In the embodiment of the invention, all the motors are three-phase asynchronous motors for intuitively explaining the rotation condition of the motors, but the invention is not limited to the three-phase asynchronous motors or servo motors in practical implementation.
As shown in fig. 13-18, the PLC program of the wire spiral winding distance tension device of the present invention is implemented as follows:
in the network 1, the wire spiral coming out of the spring machine 3 follows the first guide tube 20 into the second guide tube 22 due to the feed movement of the spring machine 3. When the first photoelectric switch 28 detects the spiral coil of the metal wire, I0.0 connected with the input end of the first photoelectric switch is closed, so that the auxiliary relay M0.0 is closed and self-locked, and meanwhile, the time delay timer T37 is powered on to start timing for 2s until M0.0 is disconnected after the timing of T37 is ended.
In the network 2, the Q0.0 coil of the tension drive motor 98 is closed by using the auxiliary relay M0.0, the tension drive motor 98 is rotated forward, the second pull claw 24 is moved in the direction of the first photoelectric switch 28, and the time counted by the timer T37 is used to determine the moving distance of the second pull claw 24.
In the network 3, after the timing of the timer T37 is finished, the auxiliary relay M0.1 is closed and self-locked, and at the same time, the timer T33 starts to time for 0.2s until the input end I0.1 of the second photoelectric switch 29 is closed, that is, the second pull claw 24 reaches the position of the second photoelectric switch 29, and M0.1 is disconnected; the timer T33 is used to give a certain waiting time to complete the step of clamping the wire coil.
In the network 4, an auxiliary relay M0.1 is used to switch on a coil Q0.3 of the electromagnetic directional valve of the second claw pulling cylinder 56 and close the electromagnetic directional valve, so that the directional valve of the second claw pulling cylinder 56 is switched, and the second claw pulling cylinder 56 extends out of the closed claw pulling cylinder to clamp the metal wire spiral coil.
In the network 5, after the timer T33 finishes timing, the auxiliary relay M0.2 is closed and self-locked until the input terminal I0.1 of the second photoelectric switch 29 is closed, that is, the second pull claw 24 reaches the position of the second photoelectric switch 29, and M0.2 is turned off.
In the network 6, the Q0.1 coil of the tension drive motor 98 is closed by the auxiliary relay M0.2, the tension drive motor 98 is reversed, and the second pull claw 24 is moved in the direction of the second photoelectric switch 29 until it reaches the second photoelectric switch 29.
In the network 7, the input I0.1 of the second photoelectric switch is turned on, so that the auxiliary relay M0.3 is closed and self-locked, and meanwhile, the energization delay timer T34 starts to time for 0.2s, and after the time is over, M0.3 is turned off. The step is a waiting step, and the next step is carried out after waiting.
In the network 8, after the timer T33 or T41 is turned on after timing is finished, the auxiliary relay M0.4 is closed and self-locked, meanwhile, the power-on delay timer T38 starts to time for 0.2s, and after the time is finished, the auxiliary relay M0.4 is turned off.
In the network 9, the Q0.0 coil of the tension drive motor 98 is closed by the auxiliary relay M0.0, the tension drive motor 98 is rotated forward, the second pull claw 24 is moved in the direction of the first photoelectric switch 28, and the time is counted by the timer T38, whereby the moving distance of the second pull claw 24 can be obtained. The webs 8 and 9 are prepared for subsequent drawing of the portion by withdrawing the second draw claw 24 back to a helical coil of wire of a certain pitch.
In the network 10, after the timer T38 is turned on, the auxiliary relay M0.5 is closed and self-locked, and at the same time, the power-on delay timer T38 starts to time for 0.2s, and after the time is over, the auxiliary relay M0.4 is turned off. M0.5 is turned off until I0.0 and I0.1 at the input of the first and second opto-electronic switches 28, 29 are turned off and the timer T40 is turned on. The function of I0.1 and I0.1 is to detect whether the wire spiral coil is broken, and if the wire spiral coil is broken, the clamping is stopped immediately.
As shown in fig. 19-22, the PLC program of the automatic blank winding and forming device of the present invention is implemented as follows:
in the network 1, when the start button is pressed, the coil I0.6 is turned on, the coil Q0.7 of the spindle motor 36 is turned on, the spindle rotates, and when the stop button is pressed, the coil I0.7 is turned on, and the spindle motor 36 stops rotating.
In the network 2, after a mandrel of the weighing sensor 100 is fully wound with a metal wire and spirally wound to a specified mass, I0.5 is triggered, the auxiliary relay M1.2 is switched on and self-locked, and meanwhile, a timer T42 is switched on in a delayed manner to start timing for 2s until the M1.2 is switched off after the timing is finished. The effect of this step is to wait 2s for the next step.
In the network 3, after the timer T42 is turned on in a delayed manner, the auxiliary relay M1.3 is turned on and self-locked until the contact I1.1 of the fourth travel switch 103 reaching the cold pressing right limit is closed, and the auxiliary relay M1.3 is turned off.
