Case Study: Zigzag Feeder & Dual-Station Decoiler for High-Efficiency Coil Processing in the New Energy Industry

In the new energy sector, especially in battery casing and structural component manufacturing, material utilization and production efficiency are crucial to controlling cost and ensuring delivery stability.
Youyi Precision’s Zigzag Feeder + Dual-Station Decoiler Automated Stamping Line provides a highly efficient, material-saving, and fully automated coil processing solution widely used across the new energy industry.

This system achieves non-stop coil changeover, high material utilization, and intelligent servo control—significantly increasing output while reducing material waste and manual operations.

1. Dual-Station Decoiler — Zero-Downtime Coil Changeover

The dual-station decoiler (also known as a dual-mandrel decoiler) features a double-spindle design that allows two coils to be loaded simultaneously.

Key Advantages

One coil runs while the other is preloaded, enabling continuous coil feeding without stopping the press line.

New coils can be loaded using a forklift or overhead crane during operation.

Each spindle is powered by a vertical motor with a reducer and chain mechanism for stable decoiling.

Contact-sensing control prevents material scratches.

Optional frequency inverter reduces vibration and allows adjustable speed.

Hydraulic expansion ensures stable clamping for heavy coils above 2 tons.

All functions—including tightening, pressing arm movement, and spindle rotation—are fully controlled through an intuitive touch-screen interface.

 

2. NC Zigzag Feeder — Maximizing Material Utilization with Precision

The NC zigzag feeder enables left-right alternating motion, allowing circular blanks to be punched in an overlapping layout, greatly improving material usage for round blanking applications.

Core Features

● High Material Utilization

The zigzag motion supports circle-to-circle overlapping blanking, minimizing raw material waste.

● Intelligent Adaptive Motion Control

The system automatically calculates shifting distances and feed steps based on the blank diameter, optimizing layout even when blank sizes vary.

● Precision Dual-Servo System

Equipped with Mitsubishi PLC + dual Yaskawa servos:

Servo 1: Drives the feed rolls for accurate forward feeding.

Servo 2: Drives a Hiwin ball screw for precise left-right zigzag shifting.

Feeding accuracy can reach ±0.08 mm, and edge spacing can be controlled within 0.5 mm, meeting high-precision stamping requirements.

● Easy Touch-Screen Operation

Operators simply input material width, blank diameter, and pitch; the system automatically calculates movement paths—no mechanical adjustments required.
