Spinning Winder Heating Roller Front Arrangement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spinning winders face difficulties in efficiently threading yarns onto multiple heating rollers due to the large and inflexible suction unit, which makes it challenging for operators to maneuver in tight spaces, especially when there are many heating rollers or they are positioned at the back.
Innovation Solution
The spinning winder design includes heating rollers on the leading end side of the winding axis with their end faces facing a working space, allowing the suction port to be inserted from the front and moved up and down, left and right along the circumferences, improving threading efficiency. Additionally, guide rollers and distribution guides are used to align yarns orthogonally with the bobbins, reducing bending angles and obstruction during threading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If heating rollers are arranged in parallel to the winding axis, then yarn threading can be performed, but the working space becomes narrow and operation efficiency deteriorates
Solution Approach 1:
The heating rollers are repositioned from a side arrangement (parallel to winding axis) to a front arrangement (orthogonal to winding axis), changing the spatial dimension of operation. This dimensional change opens up the working space from the leading end side, allowing operators to access heating rollers more easily without constrained movement in narrow spaces.
2Temperature
If the number of heating rollers is increased to sufficiently heat yarns, then heating quality improves, but threading complexity and difficulty increase
Solution Approach 1:
Multiple heating rollers are arranged in parallel on the front side, all accessible from a single working space. This merging of multiple heating functions into one accessible location allows operators to thread yarns to multiple rollers simultaneously from the leading end side, reducing the cumulative complexity that would arise from accessing each roller separately through narrow spaces.
3Temperature
If heating rollers are positioned at the back to achieve desired heating, then heating effectiveness improves, but threading becomes extremely difficult
Solution Approach 1:
Instead of positioning heating rollers at the back of the winder where they would be effective for heating but inaccessible for threading, the rollers are inverted to the front position on the leading end side. This inversion maintains heating effectiveness while fundamentally improving accessibility, allowing operators to easily thread yarns to all heating rollers from the open working space at the front.

Function Achieved in This Case
This arrangement enhances the efficiency of yarn threading by allowing operators to perform operations from a more accessible working space, reducing the complexity of yarn alignment and distribution, and maintaining efficiency even with an increased number of heating rollers.
Implementation Method 1
yarns are sucked through a suction port of a sucking unit (air sucker)

AI summary
The efficiency in yarn threading from the leading end side of a winding axis onto a plurality of heating rollers is improved. A spinning winder sends, to a winding unit below via a godet roller group 20 and two guide rollers 11 and 12, a plurality of yarns 10 spun out and serially supplied from a spinning machine above, and the winding unit winds the yarns 10. A godet roller group 20 is provided on the leading end side of a bobbin holder 7, and axes 21a to 24a of godet rollers 21 to 24 belonging to the godet roller group 20 are in parallel to the axis 7a of the bobbin holder 7.
