Its function is to rotate coils 90 degrees from a vertical "eye-to-wall" position to a horizontal "eye-to-sky" position. To ensure safety and efficiency, the system must prevent picking up multiple coils simultaneously or missing them altogether. ![](https://www.fhopepack.com/blog/wp-content/uploads/2025/12/Steel-coil-wrapping-machine2025.webp) Preventing handling errors requires a sophisticated blend of intelligent control systems, precise electronic components, and adaptable mechanical design. Here is how FHOPE ensures 100% accuracy: ### 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. **Summary:** By combining accurate data input, real-time sensor feedback, and adjustable mechanical components, FHOPE systems provide a reliable, error-free packaging operation that eliminates the risks of "doubling up" or "missed" coils. [ Explore Automated Handling Solutions > ](https://www.fhopepack.com/Automatic-Packing-Line/) ## Special Points for the Coil Packing Line **1\. Automated Weight Measurement** Accurately measures coils between 500 kg and 2,000 kg (diameter 1.2 m to 2.5 m). Ensures precision within ±1%, eliminating human error and meeting global shipping standards. **2\. Optimized Material Usage** Utilizes eco-friendly materials (0.2 mm to 0.5 mm thickness), reducing packaging waste by up to 30%. Lowers operational costs while promoting industrial sustainability. **3\. Enhanced Safety Protocols** Features automatic shut-off and overload protection for coils up to 3 m long and 1,500 kg. Significant reduction in workplace injury risks and increased employee morale. ## Precision Coil Identification & Separation To prevent coils from being picked up together or missed, FHOPE utilizes advanced **mechanical separation** and **ProfiNet synchronization**. Data is pulled directly from the factory's Level 2/ERP system, allowing high-precision Sick or Omron sensors and encoders to track and separate coils based on specific width and OD parameters. Operators can manage up to 20 specific slots per turnstile arm via the HMI. ### Technical Parameters for Separation Control | Category | Key Parameter | Technical Specification | | ------------------ | ---------------------- | ---------------------------------------------- | | Data Integration | Communication Protocol | ProfiNet for seamless ERP/MES interfacing | | Mechanical Control | Positioning Accuracy | ± 2 mm using linear precision tracks | | Detection Systems | Sensor Types | Sick/Omron proximity and photoelectric sensors | | Verification | Validation Station | Automatic weighing and barcode scanning | ### Estimated Price Range (EXW Basis) | System Type | Configuration Highlights | Price Range (USD) | | ----------------------- | ---------------------------------------------------- | -------------------- | | Standard Automated Line | Turnstile, down-ender, PET strapping, PLC tracking | $361,168 — $381,168 | | High-End Heavy Duty | Mag/Vac stackers, 11T+ capacity, Level 2 integration | $450,000 — $550,000+ | | Economic Slit Line | Automated separation for 30-300kg coils | Approx. $171,168 | #### Operational Excellence Notes: * **Safety Interlocks:** Lifter and turnstile movements are mutually locked to prevent mechanical interference. * **Centering Stations:** Automatic support rollers correct coil center positions before stacking. * **Surface Protection:** All contact surfaces are PU (Polyurethane) coated to maintain material integrity.
