Why the actual feeding length different from the set length?

1. Check the air pressure and adjust it properly. 2. Adjust the release signal start angle: when the position pin touches the sheet. 3. Check the settings if any mutiple-steps feeding setting. 4. Check if any dirty or block on the feeding path.

Why the NCF feeder servo motor does not run?

1. Verify if the motor works at automatic mode or manual mode. 2. Check if there is any alarm code on the servo drive. 3. Check if there is any alarm on control panel (touch screen). 4. Re-plug the encoder cable of the servo motor. 5. Check the parameters settings if any wrong. 6. Contact our sales for further help.

How to synchronize the 2-in-1 uncoiler straightener with the servo feeder?

Put the sensor bar (bracket with a top roller) between the 2-in-1 uncoiler straightener with the servo feeder. There is a yellow color cable inside the electric cabinet on straightener. Connect the cable to the sensor bar.

Why the feeder fails to operate at automatic mode?

1. Verify that all signal wirings are properly connected. 2. Verify the cam angle settings. 3. Ensure the auto feed and auto release switches are enabled on the HMI. 4. Confirm that the auto start button has been activated. 5. Check the monitor page and alarm page for any messages or alerts. 6. Verify the air pressure levels. 7. Check for any alarms on the servo drive unit.

Quick Start Guide of Roll Feeder

Introduction Of Roll Feeder

The roll feeder machine features a dedicated feeding head and an independently controlled electrical cabinet. It employs PLC-based control system and servo motor drive technology, ensuring high-precision material feeding with an accuracy of ±0.03mm. The machine offers adjustable feeding speeds ranging from 1 to 20 meters per minute. The feeding head is designed to integrate seamlessly with a straightener unit, while the entire system can be synchronized with both stamping presses and uncoiling machines for optimal production efficiency. All feeding rollers undergo chrome plating treatment, providing exceptional surface hardness and durability.

How To Use The Roll Feeder

Securely mount the roll feeder machine head onto the press bolster or a support bracket adjacent to the press. Connect the high-pressure air supply and electrical power input. Establish connections for the feeding and release signal wires to the press PLC. Configure the feeding pitch and speed parameters via the control cabinet's touch screen interface.
The press PLC will transmit control signals to the feeder for sheet release and feeding operations. A pneumatic cylinder governs the release and clamping functions. The servo motor drives the gear mechanism to rotate the rollers, enabling precise strip feeding.
The servo feeder offers both automatic and manual operation modes. Manual mode is intended for trial runs and initial setup. Automatic mode enables synchronized operation with the press machine. The HMI (Human-Machine Interface) provides comprehensive monitoring capabilities. In case of malfunctions or improper operations, the system will trigger visual alarms on the screen, accompanied by indicator lights and fault codes for immediate diagnosis.

Application Overview of Roller Feeder Systems‌

The roller feeder is extensively utilized in metal parts stamping production lines, where it integrates with an uncoiling machine, straightening machine, power press, and progressive die set to form a complete fully automated stamping system. For coil feeding applications, the compact 3-in-1 roller feeder offers superior performance by combining uncoiling, straightening, and feeding functions in a space-efficient design.
In cut-to-length production lines, a compact 3-in-1 straightener feeder paired with a shearing machine provides a complete solution for precise material cutting. Additionally, uncoiler-roller feeder combinations serve as essential components in profile roller forming systems, ensuring continuous material supply for consistent production.
