As the core equipment of the packaging industry, bag making machines process plastic films, paper, non-woven fabrics and other raw materials into packaging bags of various specifications through automated processes, widely serving key areas of the national economy such as food, medicine, chemicals, and daily necessities. In this industrial context, swing bag making machines have become an important branch of bag forming, filling and sealing machines.
1. Current Equipment difficulties
Precision control challenges: Roller adjustment results in dimensional deviations of up to ±1mm.
Low mold change efficiency: Mold changes take 2-4 hours, increasing costs for small batches.
Severe material loss: Tension fluctuations during high-speed molding lead to material scrapping.
2. Equipment Process Difficulties
Multi-axis Coordinated Control: Overlapping/gaps may occur when axis synchronization error exceeds 0.05mm.
High-Speed Stability: Equipment vibration amplitude exceeds 0.1mm at speeds exceeding 15m/min, affecting forming accuracy.
Cross-Sectional Distortion: Flange waves (edge waves) and web depressions are common during cold bending of U-shaped steel.
The SINEE Swing Bag Making Machine solution features a control system consisting of a SINEE HMI, SM200 series PLC, and EA series servo systems. Features include control over bag quantity and speed, setting bag length using a fly-by-fly shear, heat sealing and bag cutting functions, and PID-controlled unwinding, ensuring efficient and precise bag-making.
Operation Steps
1. Parameter Setting
Set Quantity - Set Speed - Set Bag Length: Enter the target bag length, and the system will automatically calculate the cam curve (to ensure bag-making accuracy).
2. Startup and Automatic Operation
One-button Start: After completing parameter settings, the machine will automatically start.
Automatic Operation (Continuous Feeding, Tracing Heat Sealing, Tracing Bag Cutting, PID Unwinding): The machine enters fully automated mode, completing the entire process from feeding, heat sealing, bag cutting, to unwinding.
3. Stoppage (Two Scenarios)
When Quantity Reached: When the production quantity meets the set value, the machine automatically decelerates and stops.
Premature Stop Request: To terminate production prematurely, press the Stop button to manually stop the machine.
Extremely stable, adaptable to harsh environments.
The controller (SMC200), driver (EA190E), and HMI (VMi10) are designed specifically for industrial environments. Multiple protection features effectively protect against metal dust, oil mist, and water spray; a comprehensive driver protection system includes overvoltage, undervoltage, overheating, and overload protection.
Intelligent and easy to use, convenient operation.
The user-friendly HMI interface simplifies operation.
One-touch start for automatic grinding; support for multiple languages and text labels; macros support recipe search; and universal program functionality (no conversion required for economy and basic models).
Bus integration for efficiency and precision.
EtherCAT bus architecture simplifies wiring and enables high-speed synchronous control.
1ms synchronization cycle; precise positioning (feedforward compensation, minimum settling time 5ms).
Simplified maintenance, reduced costs.
Designed for easy maintenance, reducing downtime.
The compact controller/driver design saves space; simplified wiring reduces points of failure.
Function Advantages
1. High Production Efficiency and Speed
The swing-type bag making machine boasts a production speed of 120-200 bags per minute, far exceeding traditional reciprocating machines.
2. Easy Operation and Fast Adjustment
One-touch bag length adjustment and digitalized parameters make adjustment quick and easy.
3. Wide Material Range and Good Product Adaptability
The sealing technology is compatible with a variety of materials, including PE and PP films, composite materials, and thick and thin bags, minimizing damage and ensuring aesthetically pleasing trimming.
