The automatic winding machine system adds automatic lifting function in the take-up and pay-off parts

The power supply system of the automatic winding machine mainly provides power for the industrial control computer and the motion control card. In order to protect the automatic winding machine from the impact on the system and software due to sudden power failure, this part is not shared with the rest of the electrical parts of the equipment. Instead of the power supply line, the power supply is distributed independently, and the industrial computer is equipped with a 500W regulated power supply. In the case of a sudden power failure, ensure that the industrial computer continues to run for more than half an hour. The servo drive and the equipment heating system share a power supply system, and the system power supply is 1.5 times the equipment design power.

The control signal of the servo drive of the automatic winding machine manufacturer, the state output signal of the system is output through the optocoupler isolation; the encoder is the feedback signal of the grating ruler, the limit signal, and the input of the main control operation switch signal are all input through the optocoupler on the control card. The isolation chip is fed into the control card. The electrical isolation between the industrial computer and the rest of the equipment is realized. In this way, the reliable and stable operation of the industrial control computer and the motion control card can be guaranteed to the greatest extent, and the equipment shell is safely grounded.

The d automatic winding machine system of the automatic winding machine manufacturer is composed of a servo module, a frequency conversion module, a displacement counterweight module, a PLC control module and a human-computer interaction touch screen module. When the system is running online, the take-up spindle uses vector control for active operation, and its control process includes two closed-loop systems, one is directly connected to the encoder and the motor spindle, and forms a closed-loop vector control with the frequency converter; the other is after the gear is decelerated. The spool shaft is directly connected to ensure accurate counting of turns. The pay-off motor uses the combination of PID and bang-bang to perform real-time speed matching according to the position of the counterweight module and the speed of the take-up motor. Compared with cylinder matching, this matching method expands the error range allowed by the system. Scholars have increased the system's stable operation domain. The system's cable system uses Schneider's servo controller to ensure the precision of the cable. In order to facilitate the loading and unloading of the wire reel, the system adds the automatic lifting function of the material roll in the wire take-up part and the wire pay-off part respectively. In order to ensure the safety of the system in operation, functions such as the left and right limit of the cable, the upper and lower limit of the pay-off and take-up rack, the upper and lower limit of the cable rack, the upper and lower limit of the counterweight, and emergency stop have been added.

The driven operation system of the automatic winding machine mainly includes a pay-off rack and a wire rack. The speed of the wire rack is determined by the speed of the take-up frame of the active operation system. Its speed matching accuracy determines the close-packing effect of the wire wheel. The pay-off frame must be reasonably matched with the active operation system to complete the normal take-up and pay-off work of the winding machine. It determines the follow-up performance of the entire system, and also determines the tension of the winding process and the quality of the wire wheel. .

The pay-off frame is composed of movable pulley, base, bottom plate, linear guide rail, rack, support seat, counterweight linear guide rail, fixed pulley, active motor, active support, etc. The counterweight system can be replaced with different counterweights to provide different weights. The constant tension on the wire and the addition of a pressure sensor can detect the exact weight of the counterweight, and the error is less than 1%. The auxiliary support part can be loaded and unloaded with wire pulley. There are two air cylinders installed on both sides of the column, which can lift the wire pulley. One cylinder is installed in the axial direction. The wire pulley can be tightened by the axial top to complete the installation and positioning process of the wire pulley.
