Fully Integrated Horizontal Intelligent Steel Coil Packaging Line represents a state-of-the-art solution that consolidates the entire packaging workflow—from initial retrieval to final stacking—into a single, continuous automated line.
Based on the technical standards found in the sources,this article details the systematic process and technical advantages of this high-efficiency system.
I. Automated Buffer and Retrieval: From Turnstile to Conveyor
The process begins at the Four-Arm Turnstile, which serves as a heavy-duty storage buffer for slit coils coming from the production line.
- One-by-One Retrieval: An Automatic Coil Down-Ender (or Downloader) interfaces with the turnstile to pick up coils individually.
- Orientation Transformation: The Down-Ender performs a 90-degree hydraulic flip, transitioning the coil from a vertical “eye-to-the-side” position to a horizontal “eye-to-the-sky” orientation.
- Precision Placement: Coils are then placed onto the Single Coil Power Conveyor, which features PU-covered rollers to protect the delicate edges and surfaces of the metal.
II. High-Tension PET Strapping
Once on the conveyor, the coil moves to the Automatic PET Strapping Station.
- Radial Strapping: Utilizing advanced strapping heads (often using friction welding technology), the system applies high-strength polyester (PET) straps through the eye of the coil.
- Adjustable Configuration: Operators can program the number of straps (typically 2, 3, or 4) via the HMI. The machine automatically rotates the coil to the exact degree required for each strap application.
III. High-Speed Eye-Through Wrapping
The strapped coil continues to the Automatic Orbital Wrapping Machine.
- Synchronized Protection: The machine uses a rotating ring that orbits through the core of the coil, applying protective layers (such as stretch film, VCI paper, or HDPE woven fabric).
- Advanced Features: The sources highlight features like automatic material cutting, adjustable overlap (20%–60%), and the ability to wrap two layers of different materials simultaneously for enhanced moisture and rust resistance.
IV. Out-feeding and Intelligent Clamp-Style Stacking
Following the wrapping process, the finished coil is transported to the Out-feeding Line for final inspection and weight verification.
- Clamp-Style Stacking: At the end of the line, a specialized Clamp-Style Stacking Machine (Manipulator) is utilized.
- Precision Gripping: Using a mechanical gripper or “clamp and hold” mechanism, the machine lifts the packaged coil and moves it to a designated pallet.
- Classified Discharge: Coils are stacked according to weight, width, or order number, allowing for organized storage and immediate removal by forklifts or transfer cars.
