Reciprocating Suction Section Yarn Winding Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional yarn winding devices consume excessive power due to constant suction force generation in yarn catching sections, even when not in use, leading to inefficiencies.
Innovation Solution
A yarn winding device with a reciprocating suction section that generates suction force only when needed, moving between positions to activate or deactivate the suction port, reducing power consumption by eliminating unnecessary suction force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the suction section constantly generates suction force, then the yarn catching section can reliably catch yarn ends, but power consumption increases significantly
Solution Approach 1:
The suction section operates periodically rather than continuously. A control unit activates the suction force only during specific time periods when yarn end catching is required, and deactivates it during non-operational periods. This periodic operation maintains reliable yarn catching when needed while significantly reducing overall power consumption.
Solution Approach 2:
The suction section is designed to dynamically adjust its operational state between active and inactive modes. The control unit monitors operational conditions and dynamically switches the suction force generation on or off, transforming the system from a static constant-operation state to a dynamic adaptive state that optimizes energy usage.
2Reliability
If the suction section is constantly active, then yarn ends are reliably caught, but the complexity of controlling suction activation increases
Solution Approach 1:
The control unit automatically determines when suction activation is required based on operational conditions, eliminating the need for manual intervention or complex external control systems. The system self-regulates the suction section activation/deactivation based on its own operational state, simplifying the overall control architecture while maintaining reliability.
3Ease of operation
If suction force is constantly generated, then the yarn catching section is always ready to catch yarn ends, but energy efficiency decreases
Solution Approach 1:
The suction force is generated periodically only during periods when yarn end catching is actually required, rather than continuously. This periodic activation maintains operational readiness when needed while eliminating energy waste during non-operational periods, thereby improving energy efficiency without compromising ease of operation during active periods.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device achieves efficient operation by minimizing power consumption during non-suction operations, enhancing overall efficiency and reducing the risk of yarn breakage during joining by adjusting suction force levels.
Implementation Method 1
a suction force is generated in the suction port when the suction section is at a first position that is near a yarn path of the yarn that moves from the yarn supplying section to the winding section
Implementation Method 2
a yarn-end blower that blows off a yarn end from the yarn supplying bobbin to the winding section side by blowing an air current

AI summary
In a yarn winding device (2), a yarn catching section (14; 90) includes a main body (72; 94) and a suction section (74; 96) that is constituted by a cylindrical member on which a suction port (74a; 96a) that sucks the yarn is formed. The suction section (74; 96) is arranged so as to be capable of performing a reciprocating linear movement in an axial direction of the cylindrical member in the main body (72). A suction force is generated when the suction section (74; 96) is in a first position that is near a yarn path of the yarn moving from the yarn supplying section (6) to a winding section (8), and the suction force is not generated when the suction section (74; 96) is in a second position that is retracted from the yarn path.
