Yarn Take-Up Coupler Structure for Non-Parallel Axis Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coupling devices for spun yarn take-up systems face difficulties in coupling when the axes of the male and female couplers are not parallel, leading to potential clogging and poor coupling efficiency, especially in systems with valves that can catch yarns and narrow passages.
Innovation Solution
A coupling device with a first coupler and a second coupler, featuring a cylindrical ring member, seal ring, and bias mechanism, where the ring member is biased towards the first coupler, allowing for adjustable attitude to ensure contact and communication between the couplers even if their axes are not parallel, preventing clogging and enabling smooth yarn passage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a valve is provided in the coupling device to control fluid flow, then fluid flow control is improved, but yarn clogging occurs and passage becomes narrow
Solution Approach 1:
The invention removes the valve component from the coupling device entirely. The patent explicitly states that existing coupling devices with valves cause yarn to be caught and passages to narrow, leading to clogging. The new design achieves fluid flow control through the coupling mechanism itself without requiring a separate valve, thereby eliminating the clogging problem while maintaining flow control capability.
Solution Approach 2:
The coupling device is designed to perform multiple functions: it provides fluid flow control, enables coupling/decoupling of pipes, and prevents yarn clogging all through a single integrated mechanism. The coupling structure itself controls fluid flow between connected pipes without requiring additional valve components, making the device universal and eliminating the need for separate yarn-catching prevention mechanisms.
2Adaptability or versatility
If the axis of the male coupler is not parallel to the axis of the female coupler, then adaptability to misalignment is improved, but coupling difficulty increases
Solution Approach 1:
The coupling device incorporates a movable base that can transition between fixed and horizontally movable states. When coupling, the movable base allows horizontal movement to correct axis misalignment between male and female couplers. This dynamic adjustment capability enables the system to adapt to non-parallel axes while maintaining ease of operation, as the movable base automatically compensates for alignment deviations during the coupling process.
3Adaptability or versatility
If additional components are added to the inner passage to enable coupling of non-parallel couplers, then coupling adaptability is improved, but device complexity and clogging risk increase
Solution Approach 1:
The invention merges the alignment correction function with the existing movable base structure. Instead of adding separate components to the inner passage to handle non-parallel coupling, the design integrates the alignment adjustment capability into the base that already supports the coupler. This merging approach maintains coupling adaptability while avoiding increased device complexity and clogging risk from additional internal components.

AI summary
To provide a coupling device suitable for arrangement in a pipe connected to a yarn sucking device and capable of coupling paired couplers if axes of the couplers are not parallel to each other. A first coupler 83 includes a first cylinder body 91. A second coupler 84 includes a second cylinder body 92 facing the first cylinder body 91, a cylindrical ring member 93 engaged on an outer side of the second cylinder body 92 with a gap, and movable in an axial direction of the second cylinder body 92, a seal ring 95 arranged between the second cylinder body 92 and the ring member 93, and a bias mechanism 96 biasing the ring member 93 toward the first cylinder body 91. A ring member 94 is provided on an end face of the first cylinder body 91. One coupler 84 is moved toward the other coupler 83, and an end face of the ring member 93 contacts the end face of the first cylinder body 91 via the sealing member 94, whereby an inner passage of the first cylinder body 91 is brought into communication with an inner passage of the second cylinder body 92.
