Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fiber waste collection devices in textile machines, such as false-twisting machines, face challenges in effectively separating fiber waste from air, leading to the risk of lint being discharged externally, which can cause safety and sanitary issues due to entanglement with workers.
Innovation Solution
A fiber waste collection device incorporating a cyclone separator with a shielding member that blocks lint from being discharged externally, featuring a tubular shape for air discharge and a fiber waste discharge unit, where the shielding member has a gap larger than the lint diameter and a flow rate of air discharge greater than the fiber waste discharge, ensuring effective separation and prevention of lint entanglement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a suction device is used to collect fiber waste during threading or package replacement, then fiber waste can be removed from the textile machine, but lint may be discharged to the exterior together with air, creating safety and sanitary issues
Solution Approach 1:
The suction device is segmented into multiple functional units: a cyclone separator that divides the suction flow into a fiber waste discharge path and an air discharge path, and a shielding member that further segments the air discharge path to block lint while allowing air passage. This segmentation enables separate handling of fiber waste and air flows to prevent lint discharge.
Solution Approach 2:
The shielding member acts as an intermediary element positioned in the air discharge path. It has gaps larger than lint diameter that allow air to pass through while blocking lint particles. This intermediary structure mediates between the need to discharge air and the need to prevent lint discharge to the exterior.
2Productivity
If the shielding member has gaps to allow air discharge, then air can be vented from the cyclone separator, but lint may pass through the gaps and be discharged externally
Solution Approach 1:
The shielding member has non-uniform local quality with gaps of specific dimensions (larger than lint diameter) strategically positioned to allow air passage while blocking lint. The local geometry of the gaps is optimized to differentiate between air molecules and lint particles based on size, enabling selective passage.
3Productivity
If the flow rate of air in the air discharge unit is increased, then air can be discharged more efficiently from the cyclone separator, but lint may be carried along with the high-velocity air flow to the exterior
Solution Approach 1:
The shielding member provides preliminary anti-action by blocking lint particles before they can be discharged to the exterior. It anticipates and prevents the harmful effect of lint discharge by intercepting lint in the air discharge path, allowing high-velocity air flow while stopping lint particles.

AI summary
[Problem to be Solved] The invention provides a fiber waste collection device configured to separate fiber waste from air appropriately, thereby capable of suppressing discharge of fiber waste to an exterior, and a false-twisting machine including the fiber waste collection device. [Solution to Problem] The invention relates to a fiber waste collection device including a fiber waste transfer pipe 11 for transferring fiber waste including lint, a fiber waste collection unit 13 for collecting the fiber waste transferred through the fiber waste transfer pipe 11, and a cyclone separator 30A for separating the fiber waste transferred through the fiber waste transfer pipe 11 from the air and collecting the separated fiber waste into the fiber waste collection unit 13. The cyclone separator 30A includes a fiber waste discharge unit 46 for discharging the fiber waste separated from the air into the fiber waste collection unit 13, an air discharge unit 50 for discharging air separated from the fiber waste to an exterior, and a shielding member 60 for blocking lint from being discharged to the exterior through the air discharge unit 50. The shielding member 60 has a gap larger than a diameter of the lint, and is configured such that a flow rate of air in the air discharge unit 50 is larger than a flow rate of air in the fiber waste discharge unit 46.
