Vertical Spiral Accumulator

✅ 1. Product Overview

ال Vertical Spiral Accumulator is an efficient strip storage system used in continuous production lines such as high-frequency ERW tube mills and slitting lines. Its main function is to provide temporary strip storage during coil changeover or welding, ensuring continuous, uninterrupted production.

🌀 2. Working Principle

The strip enters from the bottom and is guided upward along a spiral track for storage. It exits from the top while feeding the next stage. A frequency-controlled motor, along with tension sensors and a PLC system, regulates infeed and outfeed speeds, allowing for automated operation and tension balancing.

🔍 5. Comparison: Vertical Spiral vs. Disc Accumulator

خاتمة: Vertical Spiral Accumulators are ideal for high-speed, high-capacity applications, while Disc Accumulators are more suited for compact, mid-speed setups.

🧭 6. Application Scenarios

• ERW tube mills (for coil change buffering)

• Slitting and cut-to-length lines

• Cold roll forming lines

• High-speed coating or pickling lines

• Any continuous process requiring dynamic strip buffering
