Zigzag Servo Feeder

The SUNRUI Zigzag Servo Feeder is a specialized NC servo feeder designed for circle blanking, round cover stamping, and washer production. Unlike conventional linear feeders, it utilizes a unique X-Y axis feeding system that can stagger (zigzag) the material feed path. This intelligent staggering allows for the nesting of circular parts much closer together, significantly reducing the scrap between each stamping—achieving material savings of up to 22%.

Engineered for both efficiency and precision, the zigzag feeder is the core of a high-productivity blanking line. It seamlessly integrates with a decoiler straightener and a stamping press, making it the ideal solution for industries like motor manufacturing, appliance production, and automotive parts, where high-volume, material-efficient production of round components is essential.

How Zigzag Feeding Works?

Standard linear feeding creates large gaps of scrap material between circular blanks. The zigzag servo feeder solves this by shifting the material laterally (Y-axis) between each feed cycle (X-axis). This allows the circular parts to be "nested" or staggered closer together, much like the arrangement of cups on a tray. This intelligent nesting results in the significant material savings.

Applications for Maximum Material Savings.

• Motor Industry: Stator and rotor laminations, motor shell blanks.

• Appliance Manufacturing: Compressor shells (refrigerators, air conditioners), heater parts.

• Automotive: Clutch discs, pulley blanks, brake discs, wheel hub components.

• Household & Lighting: Cookware blanks, lamp shades, tea set components, stainless steel tableware.

SUNRUI Zigzag servo feeders are essential for industries focused on high-volume, material-efficient round blanking.

Typical Circle Stamping Line Configuration

The zigzag servo feeder is the critical second step in a complete circle stamping line.

• Decoiler Straightener: Loads the coil, uncoils, and straightens the material strip.

• Zigzag NC Servo Feeder: Precisely feeds the strip in X-Y axes to create the zigzag nesting pattern.

• Stamping Press: With the appropriate die, stamps the circular or shaped end products.

Up to 22% Material Savings

By staggering the feeding path in X-Y axes, the zigzag feeder nests round parts more efficiently, dramatically reducing scrap and material costs.

High Precision X-Y Feeding

 Powered by independent Yaskawa AC servo motors and a precision linear ball screw system, it ensures accurate and repeatable positioning for both the feed length (X-axis) and lateral shift (Y-axis).

Smart & Simple Setup

The user-friendly HMI touchscreen, controlled by a Mitsubishi PLC, automatically calculates the optimum zigzag movement pattern. Operators can quickly set up single or dual-axis feeding sequences with minimal training.

Robust & Reliable Construction: Features a pneumatic roll release system, spring-type roll pressure, and hardened feed rollers for consistent, non-slip gripping of materials.

Versatile Applications: Handles a wide range of materials (steel, aluminum, copper) from 0.2mm to 2.0mm thick and up to 800mm wide, suitable for producing various round and shaped parts.
