Disc Type Accumulator

coil accumulator to storage the coil, keep erw tube mill non stop running with high speed. this is disc type accumulator, suitable use pipe mill below 5inch, 5mm thickenss. good quality low cost.

After uncoiling and leveling, the strip enters the upper disc group, winds through several fixed discs, and exits from the bottom. This forms a vertical buffer area that automatically adjusts feeding speed based on mainline status. During coil changeover, the accumulator speeds up to maintain continuous output, ensuring non-stop production.

Specification

🔧 Main Functions & Advantages:

Uninterrupted Production: Maintains continuous material supply during coil changeover without stopping the main welding line.
High Storage Capacity: Stores up to dozens of meters of strip dynamically.
High Automation: Equipped with tension sensors and frequency converters, fully integrated with the main line.
Versatile Material Compatibility: Suitable for strip thicknesses from 0.8–5.0 mm and widths from 200–800 mm.

🧩 Equipment Composition:

Upper and Lower Disc Modules
Steel discs fixed in vertical layout; the strip passes between them to create the storage loop.
Tension Detection & Control System
Sensors or encoders monitor strip tension and send feedback to adjust motor speed.
Entry Guide System
Aligns and directs the incoming strip into the accumulator path smoothly.
Variable Frequency Drive (VFD) System
Synchronizes strip feeding speed with upstream and downstream equipment.
Safety Devices
Includes safety guards and emergency stop switches to ensure operator safety.

⚙️ Technical Specifications (Customizable)

🔍 Comparison: Disc Accumulator vs. Loop Cage

Feature	Disc Type Accumulator	Loop Cage Accumulator
Strip Stability	Excellent, controlled path	Prone to swing or wave
Installation & Maintenance	Easy and quick	Complex and time-consuming
Cost	Moderate	Higher due to structure
Automation Integration	High, easy to link with PLC	Usually passive, hard to automate
Safety	High, enclosed path	Risk of strip jumping

Conclusion: The Disc Type Accumulator is better suited for modern ERW tube mills with high automation, space-saving requirements, and stable strip handling needs.
