Fiber Sorting
Pneumatic feeding is a process that distributes loose raw fiber into a vertical reservoir for further cleaning. Inside an optical chute, high speed cameras scan the falling material to detect foreign matter or discolored clumps. This system allows a mill to remove trash without slowing down the primary production line.
Detection Logic
Sensors identify targets based on color contrast or differences in geometric shape. When the software flags an item, the optical chute activates a quick pulse of compressed air to divert the particle into a waste container. This prevents plastic film or jute strings from entering the carding machine where they would be shredded into thousands of tiny flaws.
Efficiency Target
Quality improves when machines work closer to the start of the fiber line. By using an optical chute early in the opening sequence, subsequent machines do not have to work as hard to remove fine dust. Cleaner input leads to yarns with fewer thick spots and higher overall strength.
Flow Management
Pressure inside the vertical chamber must remain constant to ensure a steady feed of fiber. While the optical chute performs its scan, it also monitors the height of the fiber column to tell the prior machine to slow down or speed up. This balancing act ensures the mill runs without gaps or blockages.
