AC SERVO MOTOR SOLUTION FOR BAG MACHINE


Project introduction

The bag making machine is a machine for making various plastic packaging bags or other material packaging bags, and the processing range thereof is various plastic bag or other material packaging bags of different sizes, thicknesses and thicknesses. In general, plastic packaging bags are the main products. ECON TECH’S AC servo motor solution for the current status of domestic heat sealing and cutting bag making machines, which was successfully applied in the domestic bag making machine equipment industry. This program selected medium-inertia high-speed 130 series AC servo motors as the main movement mechanism according to the equipment process requirements. It guarantees the smoothness and quick response of the sealing and bag-making machine's own motion under frequent starting load, so that the feeding speed of the servo motor can meet the time requirements for the up-down operation of the cutting knife. At the same time, it simplified the mechanical mechanism and solved the disadvantages of low efficiency, low positioning accuracy, high energy consumption, low level of automation, and waste of materials in the original machinery and equipment.

The ECN-GA series servo drive adopted by this machine has the characteristics of strong overload capacity, strong anti-load disturbance capability, large starting torque, and high dynamic response speed. The driver integrates the three control methods of position control, speed control, and torque control, and can perform dynamic switching of each control mode, using a more flexible and flexible; with over-speed protection, over-current, overload, overheating, main power over Pressure and under voltage, encoder abnormality, communication error, PID feedback signal abnormality and other protection and abnormal display, make the control process at a glance. It can be connected with ECON TECHs AC servo monitoring software through data lines to realize quick parameter setting and real-time monitoring of servo runtime performance, helping customers to quickly and accurately find the problem in the event of a fault. The motor is a three-phase permanent magnet AC servo motor with three times the overload capacity, a rated speed of 2500 rpm, and an encoder resolution of 2500 lines.

Mechanical parameters: mechanical transmission reduction ratio 1:3

Roller diameter: 66mm

Accuracy requirements: bag length accuracy is less than 0.5mm, servo motor encoder pulse number is 2500P/R, through the four times frequency conversion, the resolution accuracy reaches 10000p/r, so its error is far less than 0.5mm, causing larger positioning error The real reason is that the servo motor is not smooth enough to start and stop, and it will jitter when stopped. Therefore, adjust the appropriate speed loop, position loop gain, and acceleration/deceleration time according to the start/stop speed of the servo motor. Refer to the ac servo operation manual for specific debugging.
