In the feed industry, woven bags have become the mainstream packaging material due to their low cost, high strength, and good breathability.

However, in the process of automated production, traditional mechanical positioning methods are difficult to meet the modern packaging needs of diverse colors and complex patterns, especially when the base color of the feed bag is similar to the color of the cut, it is more prone to misjudgment.

Color complexity: The color of the feed bag covers basic colors such as purple, blue, yellow, and green, and there are interference factors such as reflection and printed patterns, which can easily be misjudged or missed by ordinary sensors.

Similar color codes for incisions: Feed bag incisions often use color codes that are similar in color to the bag body, requiring the use of high-precision color code sensors.

Speed adaptation: The speed of the woven bag production line can reach 80-120 meters per minute, and the sensor needs to complete color code recognition and signal output within 20ms

The Meiji Sensing ESE-10 series color code sensor provides an efficient and reliable solution to this problem through its excellent color recognition and grayscale resolution capabilities

The ESE-10 series is introduced as follows:

The Meiji ESE-10 series color code sensor integrates color mode and color code mode, and works based on the RGB three color principle;

Color code mode:

Focus on identifying grayscale differences between color codes and backgrounds; It identifies grayscale changes by detecting the intensity of reflected light on the surface of an object, without distinguishing specific color types. This mode is very sensitive to subtle grayscale differences and has a very fast response time (0.05ms), making it very suitable for position detection of high-speed moving objects

Color mode:

By illuminating the target object with three primary colors of red, green, and blue LED light sources, the reflected light is received and compared with the built-in RGB ratio to achieve high-precision color discrimination. This mode can distinguish extremely similar colors, even if the same color scheme has slightly different shades, it can accurately recognize them

Operation suggestion:

Priority use of color mode: feed bags come in various colors or have similar color codes;

Backup color code mode: In high-speed production lines, use color code mode to improve response speed.

1. High precision detection: Based on RGB LED technology, it can identify subtle color and grayscale differences, and can reliably work even if the background is similar to the marked color

2. High speed response: With a response time of 0.5ms in color code mode, it meets the requirements of high-speed production lines and ensures accurate cutting positions

3. Strong anti-interference ability: With excellent environmental light anti-interference characteristics (up to 3000Lux), it can adapt to changes in lighting in industrial environments

4. Simplified maintenance: IP67 protection level resists dust and moisture invasion, reduces downtime, and lowers maintenance costs

5. Flexible adaptation: digital display screen+simple teaching function, making parameter setting and device debugging easier and faster

By combining the PLC high-speed counting module and dual-mode control algorithm used by users, a cutting accuracy of ± 0.5mm is achieved, and the scrap rate is reduced from the industry average of 3.2% to below 0.15%.
