Pinch-Pull Packaging Machine
Equipment Intro & Key Metrics
The pinch-pull vertical packaging machine is an advanced automated solution designed for the packaging industry, primarily used for processing powders, liquids, and pastes. By utilizing a pinch-and-pull mechanism on the packaging film to achieve tight sealing, this equipment boasts user-friendly operation, high packaging precision, and excellent adaptability. It is widely deployed across the food, daily chemical, and pharmaceutical sectors.
Process & Workflow Diagram
Industry Pain Points
Complex Kinematic Conversion
The film-feeding mechanism uses a concentric slider-crank structure. This requires the control program to accurately convert rotational displacement into linear displacement in real-time, placing high demands on algorithms.
High-Precision Registration
It requires capturing the color mark sensor signal via DI and recording the film-feeding axis position in real-time to calculate the offset, preventing cumulative errors that lead to cutting deviation.
Dynamic Pacing Adjustment
The servo speeds must be dynamically adjusted based on the target machine speed and fixed pneumatic parameters to ensure optimal synchronization and production efficiency.
Mechanical Installation Tolerances
Discrepancies in the home position setup of each machine can lead to inaccurate film feeding. Without a software calibration function, equipment commissioning becomes highly difficult.
FLEXEM Solution Architecture
The control system is powered by the FLEXEM FC5M-30MN PLC, paired with the FE7070WE-4G, a 7-inch high-resolution HMI that provides superior visual and IoT-enabled interactions. The drive layer utilizes the FV3S-R3 rotary servo drive and the EAM series 750W rotary motor for the film-feeding axis. Built-in function blocks, including `MC_MoveFeed` (interrupt fixed-length control) and extreme value logic, perfectly accommodate high-frequency demands.
Core Advantages
Precise Mark Tracking
By capturing and processing the actual film position in real-time via sensor signals, the system ensures highly accurate cutting, fundamentally eliminating cutting point offset issues.
Smart Algorithms & Home Calibration
Built-in slider-crank conversion algorithms guarantee precise positioning. Furthermore, the supported home calibration feature effectively compensates for mechanical installation tolerances.
Automated Speed & Pacing Optimization
The system automatically adjusts the machine's operational rhythm based on the target speed. It maintains exceptional cutting accuracy while ensuring a high-efficiency output of 30-50 bags/min.
Superior HMI & IoT Capabilities
The FE7070 series HMI, equipped with a high-performance CPU, delivers an outstanding visual experience. Combined with remote IoT features, it drastically improves system maintainability.
