Texturing Zone Alignment for Compact Yarn Winding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for texturing and winding multiple threads are not compactly arranged and are not adaptable to varying production speeds, leading to inefficiencies in thread production, particularly in melt spinning and texturing processes.
Innovation Solution
The cooling device, twisting device, and at least one delivery roller are aligned in the same direction as the winding spindle, allowing for a compact and variable arrangement that minimizes machine pitch and eliminates the need for additional thread deflections, enabling a straight yarn path through the texturing zone for gentle crimping and post-heat treatment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the cooling device, twisting device and delivery rollers are arranged in a vertical arrangement (conventional design), then the devices can process multiple threads, but the machine pitch becomes large and the arrangement is not compact
Solution Approach 1:
The patent transitions from a vertical arrangement to a horizontal arrangement of the texturing zone, aligning it parallel to the winding spindle instead of perpendicular. This dimensional change allows the cooling device, twisting device, and delivery rollers to be positioned horizontally, significantly reducing the machine pitch and creating a more compact overall structure while maintaining processing capability for multiple threads
2Ease of operation
If additional thread deflections and guides are added to accommodate non-parallel arrangement, then threads can be guided to winding points, but the texturing process becomes more complex and harsh
Solution Approach 1:
The patent eliminates the need for additional thread deflections and guides by directly aligning the texturing zone parallel to the winding spindle. This extraction of unnecessary intermediate components simplifies the thread path, allowing threads to travel in a straight line from the delivery rollers through the texturing zone to the winding points, thereby reducing operational complexity and preventing harsh treatment of the threads
3Productivity
If the texturing zone is arranged perpendicular to the winding spindle (conventional design), then winding can be performed, but the distance between devices must be large reducing productivity
Solution Approach 1:
The patent merges the texturing zone and winding device into a closely integrated horizontal arrangement, with the texturing zone positioned directly above the winding device and both aligned parallel to each other. This merging eliminates the need for large distances between devices, allowing the thread path to be short and direct, thereby increasing production speed and productivity
4Volume of moving object
If the texturing zone is arranged parallel to the winding spindle with minimal distance, then machine pitch is reduced, but precise alignment and positioning become more difficult
Solution Approach 1:
The patent employs preliminary alignment actions during the design and setup phase, positioning the texturing zone and winding device in their final horizontal parallel arrangement before operation. The delivery rollers are pre-positioned to ensure straight thread paths, and the entire system is configured to maintain precise alignment, thereby achieving minimal machine pitch while ensuring the necessary manufacturing precision through advance preparation
