What is the difference between roller feeder and NC pneumatic servo feeder

The Feeder: An Indispensable Tool for Punch Press Automation

There is a wide range of punches, applicable materials, and processing techniques in punch press operations. To accommodate these variations, different types of feeders have been developed. These include pneumatic feeders, roller feeders, and NC pneumatic servo feeders. In this article, we will focus on the working principles of two commonly used models, aiming to assist customers in their selection and optimal usage.

1. NC pneumatic servo feeder: Precision and Versatility with Advanced Control Systems

The NC pneumatic servo feeder, also known as a NC feeder, utilizes a servo motor-driven feeding roller, with control of the servo motor being achieved through a touch screen and PLC. This advanced control system enhances the feeder's performance and flexibility.

Advantages of NC pneumatic servo feeder:

- Features easy operation and set-up via the touch screen

- Offers a wide application range for various operations

- Allows for high degree of customization to meet specific requirements

- Delivers high feeding accuracy

2.Roller Feeder: Enhancing Performance with Mechanical Precision

Also known as a mechanical feeder, the roller feeder operates on a principle similar to that of stone grinding tofu. The output shaft of the punch drives a pull rod, which in turn, pulls the rocker arm of the roller feeder. As a result, the transmission shaft undergoes reciprocating motion, translating this power into the unidirectional feeding motion of the feeding roller through a unidirectional device. Additionally, QIAOSEN roller feeders are equipped with a brake device to prevent the feeding roller from retreating.

Advantages of Roller Feeder:

- Provides high cost performance

- Requires no additional air source or power supply

- Exhibits high mechanical transmission stability

- Boasts a low failure rate

By understanding the distinct characteristics and advantages of roller feeders and NC pneumatic servo feeders, customers can make informed decisions, choosing the most suitable feeder for their punch press operations.
