Specification

✅ 1. Product Overview

🌀 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.

⚙️ 3. Technical Specifications (Example)

Item	Specification Range
Accumulator Height	2 – 8 meters (customizable)
ストリップ厚さ	0.8 – 4.5 mm
ストリップ幅	200 – 800 mm
Storage Length	30 – 120 meters (depending on loops)
Line Speed	0 – 120 m/min
Control System	PLC + Inverter + Tension Sensor

🏗️ 4. Main Components

Spiral Guide Track – Guides strip in a vertical spiral motion for storage.
Entry/Exit Guide Systems – Ensures smooth strip entry and discharge.
Tension Control System – Balances strip tension during storage.
Drive Motor System – Controls strip speed via frequency inverter.
Safety Systems – Includes guards, limit switches, and emergency stops.

🔍 5. Comparison: Vertical Spiral vs. Disc Accumulator

Feature	Vertical Spiral Accumulator	Disc Type Accumulator
Storage Capacity	High	Medium
Space Efficiency	Vertical structure, small footprint	Larger footprint
Structural Complexity	Higher complexity and cost	Simpler structure, moderate cost
Strip Stability	Very stable, guided path	Stable, shorter path
Automation Compatibility	Excellent, fully PLC controlled	High automation compatibility
Installation & Maintenance	Requires precision, complex setup	Simple installation and maintenance
Suitable Speed	Mid-to-high speed lines	Mid-speed lines

Conclusion: 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

🎯 7. Selection Guide

Selection Criteria	Recommendation
Line Speed	Use spiral type if over 80 m/min
Floor Space Constraints	Spiral is preferred if vertical space is available
Buffering Length	Choose spiral for long strip storage
Tension Control Requirements	Spiral offers better control
Budget Consideration	Disc type is more cost-effective for general use
