Basic Specification: Automatic Packing Line for Cold/Hot Rolled Coils
Overview
In the era of Industrial 4.0, the end-of-line packaging for metal coils—whether Cold Rolled (CR), Hot Rolled (HR), Galvanized, or Stainless Steel—is no longer just a protection step but a key factor in operational efficiency. This technical specification by the FHOPE Team outlines the standardized configuration for a high-performance automatic master coil wrapping system.
I. System Architecture: Core Components
A professional coil packaging line consists of six essential modules designed for seamless integration:
1. Main Orbital Wrapping Unit
The "heart" of the system, this unit features a specialized orbital ring that travels through the coil eye.
- Key Functions: Automatic material feeding, precise tension control, and automatic cutting.
- Adaptability: Automatically adjusts its vertical position based on the coil's Outer Diameter (OD).
2. Dual Coil Transport Trolleys
To ensure non-stop production, the line includes two heavy-duty trolleys.
- Workflow: While one coil is being wrapped, the second trolley loads the next coil, reducing idle time by up to 40%.
3. HMI Intelligent Control Station
A user-friendly touchscreen interface serves as the brain of the operation.
- Capabilities: Real-time monitoring of wrapping speed, throughput statistics, and error diagnostics.
4. Climate-Controlled Electrical Cabinet
To ensure longevity in harsh industrial environments (high dust or heat), the control cabinet is IP55 rated and equipped with an integrated air conditioning system for the PLC and drives.
5. Advanced Hydraulic System
Supplies the necessary force for orbital locking and precise positioning, ensuring smooth mechanical movements during high-speed cycles.
6. 1-Year Preventive Maintenance Kit
Includes essential wear parts to ensure the line maintains maximum uptime from day one.
II. Key Functional Highlights
- Automatic Centering: The system detects the coil's position and aligns it perfectly with the wrapping ring to prevent asymmetrical packaging.
- Integrated Safety Systems: Compliance with CE Standards, featuring 1800mm high safety fences, light curtains, and emergency interlocks.
- High Throughput: Capable of processing 10+ coils per hour, depending on material specifications.
- Dual Material Wrapping: Supports the simultaneous application of two layers (e.g., Stretch Film + Bubble Wrap) for enhanced anti-corrosion and physical protection.
- Variable Overlap Control: Operators can adjust the film overlap rate between 20% and 50% via the HMI.
III. Technical Specifications (Coil Requirements)
To ensure optimal performance, the coils should fall within the following parameters:
| Feature | Specification Range |
|---|---|
| Inner Diameter (ID) | 500 mm – 850 mm |
| Outer Diameter (OD) | 800 mm – 1250 mm |
| Coil Width | Up to 2000 mm (Min. 600 mm) |
| Maximum Weight | < 5,000 kg (5 Metric Tons) |
