Yarn Production System with Bundling Guides for Cooling Uniformity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing yarn production systems face issues with uneven cooling of filaments spun out from a single spinneret, leading to deteriorated yarn quality due to airflow disturbances between filament groups as they approach oil supply guides.
Innovation Solution
The system incorporates a virtual partitioning plane to divide discharge ports into two groups, with bundling guides placed above the oiling unit to temporally bundle filaments, reducing the space between them and minimizing airflow disturbances, ensuring consistent cooling and efficient oil application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If filaments are spun out from a single spinneret and divided into groups to form multiple yarns, then production efficiency is improved, but the space between filament groups causes airflow disturbance and uneven cooling
Solution Approach 1:
The discharge ports of the single spinneret are divided into multiple groups (first discharge port group and second discharge port group) based on a virtual partitioning plane. This segmentation allows filaments to be divided into separate groups that form different yarns while maintaining controlled spacing, resolving the contradiction by enabling multi-yarn production from one spinneret without causing airflow interference between groups
Solution Approach 2:
The virtual partitioning plane is introduced as a conceptual dividing line extending in the vertical direction, creating a new dimensional framework for organizing discharge ports. This allows filaments to be routed to different oil supply guides on opposite sides of the partitioning plane, eliminating space-related airflow disturbances while maintaining production efficiency
2Manufacturing precision
If a virtual partitioning plane is introduced to divide discharge ports into two groups, then filament grouping and oil supply are improved, but device complexity increases
Solution Approach 1:
The virtual partitioning plane acts as an intermediary conceptual tool that organizes discharge ports and guides filaments to appropriate oil supply guides without requiring physical partitioning structures. This mediator enables precise filament grouping and oil supply routing while avoiding the addition of complex physical components, thus improving manufacturing precision without significantly increasing device complexity

AI summary
An object of the present invention is to properly cool filaments in a structure in which the filaments are spun out downward from a single spinneret, divided into two groups, and bundled as two yarns. A yarn production system 1 includes (i) a spinning apparatus 2 including a spinneret 24 provided with discharge ports 26, (ii) a cooler 4 provided below the spinneret 24, and (iii) an oiling unit 5 provided below the cooler 4. A virtual partitioning plane X divides the discharge ports 26 into a first discharge port group 26A and a second discharge port group 26B. The oiling unit 5 includes a first oil supply guide 51a including a first oil supply surface 52a and a second oil supply guide 51b including a second oil supply surface 52b. The yarn production system 1 further includes a first bundling guide 30a and a second bundling guide 30b which are provided below the cooler 4 and above the oiling unit 5. The distance between the first bundling guide 30a and the second bundling guide 30b is shorter than (i) the distance between the first oil supply guide 51a and second oil supply guide 51b of the oiling unit 5 and (ii) the distance between the barycentric position of the first discharge port group 26A and the barycentric position of the second discharge port group 26B.
