How to prevent coils being picked up missed together in coil packing line

1. Intelligent Coil Width Data Integration

The first line of defense is ensuring the lifter knows exactly what it is picking up. Correct width information is fed into the control system through four primary methods:

• Manual HMI Input: Operators input dimensions directly into the Human Machine Interface.
• Barcode Scanning: Advanced scanners read width data directly from coil labels, eliminating human entry errors.
• PLC Data Sharing: Real-time synchronization with upstream slitting lines via Ethernet or Profibus protocols.
• ERP/MES Integration: Automated lines pull live data via API from company management systems for seamless, hands-free operation.

2. Precision Sensors & Encoder Feedback

Accurate positioning is achieved through high-precision sensors and encoders that feed real-time data to the PLC. Sensors detect the exact location of the coil on the conveyor, while encoders monitor the lifter’s micro-movements. This feedback loop ensures the lifter never overlaps onto adjacent coils, regardless of how narrow the slit coils may be.

3. Adaptive Mechanical Lifter Technology

The mechanical lifter is engineered with extension and shrinking capabilities. It automatically adjusts its physical reach to match the pre-set coil width. Combined with a calibrated hydraulic system, the lifter manages the specific loading weight of each coil, ensuring that only the targeted unit is handled, preserving product integrity and preventing dangerous uneven loading.
