Yarn Catch Part Linear Movement for Joining
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional yarn winding machines face inefficiencies in yarn joining operations due to complex mechanisms, increased time cycles, and waste yarn generation, limiting layout freedom and production efficiency.
Innovation Solution
A yarn winding machine configuration that includes a bobbin support, winding part, yarn joining device, yarn guide part, and yarn catch part, where the yarn catch part moves to introduce the disconnected yarn to the joining device without complex drive mechanisms, and uses air suction or clamps for reliable catching, with a yarn retraction mechanism to prevent tangling and optimize yarn guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the yarn guide part is swung to guide the yarn to the yarn joining device, then the yarn can be guided to the joining device, but the mechanism becomes complex and the time cycle increases
Solution Approach 1:
The patent extracts the swinging motion from the yarn guide part and replaces it with a linearly movable yarn catch part. The yarn catch part moves along the yarn travel path to catch and introduce the yarn end directly to the yarn joining device, eliminating the complex swinging mechanism while maintaining effective yarn guidance capability.
2Ease of operation
If the yarn guide part is swung to guide the yarn, then the yarn can be introduced to the joining device, but the time cycle for yarn joining increases
Solution Approach 1:
The patent replaces the mechanical swinging system with a linear movement system. The yarn catch part moves linearly along the yarn travel path to catch and introduce the yarn end directly to the yarn joining device, reducing the time required for yarn introduction compared to the arc-shaped swinging motion of conventional yarn guide parts.
3Adaptability or versatility
If the yarn catch part moves along the yarn travel path, then the layout freedom is improved, but the yarn may tangle without retraction mechanism
Solution Approach 1:
The patent incorporates a yarn retraction mechanism that retracts the yarn along the yarn travel path when the yarn catch part moves. This preliminary action prevents the yarn from tangling during the movement of the yarn catch part, enabling layout freedom without the harmful effect of yarn tangling.

AI summary
Provided is a yarn winding machine that is able to improve the degree of freedom in a layout, to guide a yam to a yarn joining device in a short time, and also to reduce the amount of a waste yam which is generated in yarn joining. Means therefor is as follows. An automatic winder includes a bobbin support part (7), a winding part (8), a yam joining device (14), a yarn guide part, a yam trap (15), and a yarn trap driver (47). The yam guide part guides a yam of a package (30) side to the yarn joining device (14) under a state where a yarn is disconnected. The yarn trap (15) is arranged so as to face a yarn travel path between the winding part (8) and the yam joining device (14), and configured to catch a yarn of a yam supply bobbin (21) side under a state where a yam is disconnected. The yam trap driver (47) moves the yarn trap in such a direction that the yarn caught by the yam trap is introduced to the yarn joining device (14) while keeping a condition in which the yam is across the yam joining device (14).
