Debugging principle of automatic winding machine console
1. Jog debugging
The main purpose of jog debugging is to find out the problems existing in the installation, electrical wiring and PLC program of the automatic winder, so as to lay a good foundation for future debugging.
(1) Manually operate the actuators and observe whether the actuators are operating normally, mainly including the steering of asynchronous motors and servo motors, and the direction of action of pneumatic actuators.
(2) Test whether each limit switch and proximity switch work.
(3) The operation of the program is monitored by the PLC programming software to check whether the input signals of the encoder and correction sensor are normal.
2. Debugging without winding materials
The purpose of commissioning without materials is to further improve the performance of the control system and prepare for commissioning with materials.
Switch the winding servo knob to the automatic winding state, switch the spindle knob to the winding state, press the foot switch, the spindle starts to rotate, keep the spindle speed constant, and observe whether the winding servo movement speed is constant; adjust the potentiometer to change the spindle Rotation speed, observe whether the moving speed of the cable servo changes accordingly. If the above functions can be achieved, carry out belt debugging.
3. Debugging of winding tape materials
(1) Wiring error. The winding tape material adjustment adopts the sequence of low speed first and then high speed. Pay attention to the cable error. There are many factors that cause errors. When analyzing the error, a comprehensive analysis should be carried out from both the mechanical and PLC program. If the wiring error value changes randomly, regardless of the size, check the timing and calculation of the sending pulse in the PLC program through the monitoring function to see if there is any error; if the error value is fixed, check whether there is any error in the wire diameter calculation, wire diameter compensation, spindle pulse number detection, etc. Problem: If the error value gradually increases, the focus should be on whether there is accumulated error on the arrangement line.
(2) Winding parking inertia. During the commissioning process, the error of too many sets of turns caused by inertia when the spindle stops at different masses and different speeds was tested. It is found that resistance error is a binary function of quality and speed, and it is difficult to determine its specific relationship. Finally, inertia compensation is used. Test the resistance error generated when the largest mass coil stops at the highest speed to ensure that the spindle enters the low-speed working area, and introduce an inertia compensation coefficient. The value of the inertia compensation coefficient is generally very small, which is determined by the trial and error method. If the value is too large, it will cause the spindle to start and stop multiple times before reaching the set distance, which will affect efficiency; if the value is too small, the actual winding resistance will exceed the set distance.
(3) Wire diameter compensation. Since different transformer manufacturers have different specific requirements for the tightness of the coil, this value needs to be tested by the transformer manufacturer according to the wire diameter and specific index requirements, and the test results can be drawn into the experience table.
