Yarn Threading Robot Horizontal Movement Above Packages
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In spun yarn winding systems, the yarn threading robot often interferes with operators or apparatuses collecting packages, leading to delays in yarn threading due to the need to move the robot away from the collection area.
Innovation Solution
The yarn threading robot is designed to move above the package ejection space, allowing simultaneous movement and package collection, with a minimized projected area to avoid collisions, and equipped with sensors to detect obstacles and restrict torque to prevent accidents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the yarn threading robot is positioned to perform threading operations, then yarn threading can be automated, but the robot may interfere with operators or apparatuses collecting packages
Solution Approach 1:
The yarn threading robot is positioned above the take-up units and moves in the left-right direction (horizontal dimension) rather than approaching from the front. This vertical positioning and horizontal movement path allows the robot to operate in a different spatial dimension than the package collection area, eliminating interference between the two operations.
2Adaptability or versatility
If the yarn threading robot moves to another winding device to thread yarns, then threading can be performed on multiple devices, but the robot may collide with operators or apparatuses collecting packages
Solution Approach 1:
The robot moves horizontally above the take-up units rather than moving forward through the workspace. This dimensional change in movement path allows the robot to access multiple winding devices without crossing into the package collection zone, eliminating collision risks while maintaining multi-device versatility.
3Reliability
If the yarn threading robot is moved to prevent interference with package collection, then safety is improved, but the completion of yarn threading is delayed
Solution Approach 1:
The robot can continuously perform yarn threading operations on multiple take-up units without interruption or repositioning delays because its horizontal movement path above the units does not intersect with the package collection operations. This continuous operation eliminates time loss while maintaining safety.
4Ease of operation
If the yarn threading robot operates in the workspace, then threading operations can be performed, but the projected area of the robot increases collision risk
Solution Approach 1:
The robot operates in the vertical dimension above the take-up units with its main body positioned high and only the arm extending downward for threading. This dimensional arrangement minimizes the robot's projected area in the horizontal workspace, reducing collision risk while maintaining threading functionality.

AI summary
In a spun yarn winding system, a yarn threading robot is less likely to interfere with an operator or an apparatus which collects packages. Take-up units 3 are lined up in the left-right direction. Each take-up unit 3 is configured to take up yarns Y spun out from a spinning apparatus and form packages by winding the yarns Y into bobbins B. A yarn threading robot 4 is provided above a winding unit 14 of the take-up unit 3, and hangs down from a guide rail 35 extending in the left-right direction over the take-up units 3 and moves in the left-right direction along the guide rail 35. At least when moving along the guide rail 35, the yarn threading robot 4 is positioned above the upper end of a fully-wound package P attached to a bobbin holder 24.
