Adjustable Stop Mechanism for Bobbin Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Spinning bobbins of varying lengths, particularly shorter ones, are not securely positioned on existing spinning bobbin carriers, leading to operational issues and thread breakages due to lack of precise positioning, as they can become displaced axially, causing interruptions in the twisting machine's operation.
Innovation Solution
A spinning bobbin carrier with an adjustable stop mechanism that can be moved between a use position and a retractable position, allowing for safe accommodation of shorter bobbins while maintaining stability and allowing standard-length bobbins to be positioned beyond the stop, ensuring secure fixation and easy adaptation to different lengths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the receiving area is shortened to accommodate shorter bobbins, then positioning precision for non-standard bobbins is improved, but the ability to accommodate standard-length bobbins is reduced
Solution Approach 1:
The stop is made movable rather than fixed, allowing it to be adjusted between different positions. The stop can be moved axially along the receiving body to accommodate bobbins of different lengths, transforming a static structure into a dynamic one that adapts to varying requirements.
Solution Approach 2:
The position of the stop is changed as a variable parameter. By adjusting the stop's position along the receiving body, the effective receiving area length is modified to match the bobbin length, allowing the same receiver to handle both standard and non-standard bobbins.
2Device complexity
If the stop is fixed in position, then the structure is simple, but it cannot accommodate bobbins of different lengths
Solution Approach 1:
The stop is made movable rather than fixed, allowing it to be adjusted between different positions. The stop can be moved axially along the receiving body to accommodate bobbins of different lengths, transforming a static structure into a dynamic one that adapts to varying requirements.
3Stability of the object's composition
If the receiving area is shortened for non-standard bobbins, then positioning stability is improved, but the receiving area length for standard bobbins is reduced
Solution Approach 1:
The position of the stop is changed as a variable parameter. By adjusting the stop's position along the receiving body, the effective receiving area length is modified to match the bobbin length, allowing the same receiver to handle both standard and non-standard bobbins.

AI summary
The invention relates to a spinning bobbin holder for a twisting machine, in particular a ring twisting machine, with a receiving body rotatably mounted about a support axis and a receiving area for arranging a spinning bobbin on the receiving body. To provide a spinning bobbin holder that can also be operated safely and reliably with non-standard spinning bobbins of varying lengths, it is provided that at least one stop is adjustable in the receiving area between a working position and a retracted position such that, in the working position, the receiving area is shortened to accommodate a shortened spinning bobbin, and in the retracted position, a regular spinning bobbin can be arranged in the receiving area projecting beyond the stop.
