In the metal processing industry, the downstream packaging process has long constrained overall capacity improvement. Traditional manual packaging methods are fragmented, highly dependent on personnel, and prone to frequent production stoppages, becoming a core pain point for steel processing manufacturers seeking to reduce costs and increase efficiency.
KINGREAL SLITTING has developed a fully automated steel coil packaging line, deeply adapted to the entire steel slitting production process. It comprehensively assists steel processing enterprises and coil manufacturers in establishing a closed-loop production capacity encompassing slitting, post-processing, packaging, and warehousing. Relying on automated operation, it completes all processes—automatic bundling, intelligent sorting, finished product warehousing, and information labeling—after slitting, creating a seamless production line. By using steel slitting lines and the slitting coil package line line in tandem, workshop capacity can be maximized, achieving an efficiency upgrade for the entire coil processing production line.
Integrated Coil Processing and Packaging System
The KINGREAL SLITTING steel coil packaging line integrates multiple modules such as intelligent sorting, precise stacking, and automated warehousing to create a composite coil processing and packaging system, reconstructing the downstream packaging production system for steel. This integrated slitting coil package line line combines sorting and conveying, positioning and alignment, finished product stacking, closed-loop packaging, and warehousing, significantly improving the precision of coil processing and overall operational efficiency.
Notably, the KINGREAL SLITTING steel coil packaging line utilizes a PLC intelligent central control system to achieve coordinated operation of all modules, completely eliminating downtime and ensuring smooth production operations in the workshop. Simultaneously, the slitting coil package line drastically reduces the frequency of manual intervention, optimizes the entire coil post-processing process, and avoids problems caused by manual operation, such as inconsistent packaging tightness, stacking misalignment, label adhesion deviation, and damage to steel coils.
Through standardized mechanized operations, it ensures consistent and stable packaging quality for each batch of steel coils, balancing production efficiency and finished product appearance, providing steel companies with a high-efficiency, high-quality, and low-loss automated coil packaging solution.
Overview of Main Functions of Steel Coil Packaging Line
KINGREAL SLITTING slitting coil package line boasts comprehensive functionality tailored to the diverse processing needs of various metal coils. Its process layout aligns with the steel slitting line's output logic, encompassing basic standard functions and numerous optional customized features. A single steel coil packaging line can complete over ten post-processing steps, adapting to various metal coil processing scenarios. Key functions are detailed below:
1) Single coil separation
As the first core process of the slitting coil package line , the equipment connects to the steel slitting line's output port, automatically separating continuous coils and discharging individual coils independently. This precisely matches the subsequent packing cycle time, preventing steel coil congestion and stacking issues, ensuring the steel coil packing line operates at a uniform and stable speed.
2) Net weight weighing and labeling (Optional)
The steel coil packaging line can be equipped with an intelligent weighing module to automatically calculate the net weight of the finished steel coil. The accompanying labeling system has two operating modes: one is fully automatic label dispensing and labeling, requiring no manual intervention; the other is fully automatic label dispensing with manual assistance, adapting to flexible production needs and quickly labeling production information such as net weight, specifications, and batch number of the steel coil.
3) Intelligent strapping with dual-material heads
KINGREAL SLITTING slitting coil package line supports a dual-head design, simultaneously equipping it with PP and PET strapping heads to meet the diverse packaging needs of metal coils. PP strapping is soft and does not damage the surface of the coil, suitable for strapping non-ferrous metal coils such as copper and aluminum strapping; PET strapping is high in hardness, tensile strength, and load-bearing capacity, suitable for strapping hard steel coils such as iron plates, silicon steel, and cold-rolled steel. The dual-head configuration allows a single steel coil packaging line to be compatible with the production of multiple types of coils, improving equipment versatility.
4) Intelligent centering
Steel coils are prone to misalignment and deviation after long-distance conveyor belt transport, affecting subsequent packaging accuracy. KINGREAL SLITTING slitting coil package line is equipped with a double-sided mechanical centering mechanism that dynamically corrects the coil's position throughout the process, ensuring centered transport and neat packaging, avoiding packaging damage and misalignment caused by deviation.
5) Outer braided strapping packaging
Based on customized packaging solutions according to customer production needs, the steel coil packaging line automatically completes the outer braided strapping protection, resisting friction, impacts, and dust corrosion during transportation and storage, protecting the finished steel coil's appearance.
6) Finishing treatment of the packaging straps
The slitting coil package line offers two finishing options: The first is a fully automatic PE film finishing process, which has higher material costs but is fully automated with no operational bottlenecks, making it suitable for high-capacity production lines. The second is a safe semi-automatic finishing process. After the steel coil is packaged, the steel coil packaging line automatically pauses operation, allowing workers to safely enter the equipment to tidy up the end of the strapping. The equipment restarts after pressing the reset button, mitigating the risk of mechanical injury from the outset and balancing cost and production safety.
7) Gross weight weighing and labeling (optional)
After outer packaging, the slitting coil package line performs a second weighing to calculate the overall gross weight, simultaneously matching both fully automatic and semi-automatic labeling modes to complete product information labeling and meet steel warehousing and outgoing quality inspection requirements.
8) Secondary centering and multi-mode material stacking
After completing all packaging processes, the steel coil packaging line undergoes precise alignment and calibration again, offering three output options: first, finished steel coils are directly stacked and stored on the ground; second, they integrate with the company's existing conveyor equipment, linking with the factory's warehousing production line; and third, multiple coils are automatically stacked and packaged, with the entire coil then wrapped in plastic film for sealing, suitable for bulk warehousing and full-truckload shipments.
In summary, the KINGREAL SLITTING fully automated slitting coil package line integrates sorting, weighing, labeling, bundling, packaging, straightening, stacking, and conveying functions, replacing multiple manual labor positions with a single machine. This minimizes manpower input in the workshop, reduces the effort required for manual management and operations, and reduces long-term labor costs for enterprises. Furthermore, the steel coil packaging line seamlessly integrates with the KINGREAL SLITTING steel slitting line, operating as a complete production line, creating a closed-loop production process from steel cutting to finished product packaging, significantly increasing overall workshop capacity.
