Yarn Winding Tension Display for Suction-Gun Threading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing yarn winding apparatuses require operators to manually adjust yarn tension using tensiometers, which increases workload and leads to yarn waste due to the need to temporarily deposit the suction gun, especially when low tension is required, making it difficult to precisely grasp the tension of the yarn.
Innovation Solution
A yarn winding apparatus with a display unit that shows tension values measured by a tensiometer at a visually observable position for the operator, allowing easy tension monitoring during yarn threading, and a simplified structure with the tensiometer positioned upstream of the bobbin holder to reduce the need for manual adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the operator uses a handy-type tensiometer to measure yarn tension, then the tension can be measured, but the operator must temporarily deposit the suction gun on a fixing stand, increasing workload and yarn waste
Solution Approach 1:
The patent combines the tensiometer and display unit into an integrated system that operates continuously without requiring the suction gun to be deposited. The tensiometer is positioned to measure yarn tension while the display unit shows the reading at the operator's location, eliminating the need for manual intervention and fixing stand usage.
Solution Approach 2:
The display unit provides real-time feedback of the tension measurement to the operator during the yarn threading process. This continuous feedback mechanism allows the operator to monitor tension values without interrupting the suction gun operation, reducing workload and yarn waste while maintaining measurement accuracy.
2Measurement precision
If the fixed-type tensiometer is used, then the tension measurement is available, but the display position is away from the working space, requiring the operator to go to the control monitor after depositing the suction gun
Solution Approach 1:
The display unit is positioned at the operator's location in the working space, changing the spatial dimension of information delivery from a remote control monitor to an accessible display near the suction gun. This allows the operator to view tension values without moving away from the working area or depositing the suction gun.
3Stability of the object's composition
If the suction gun keeps sucking the yarn after being deposited on the fixing stand, then the yarn is held, but the yarn is wasted, especially when low tension is required
Solution Approach 1:
The real-time tension measurement and display provide continuous feedback that allows the operator to precisely control the suction gun's operation. When the desired tension is achieved, the operator can stop the suction gun immediately without needing to deposit it on a fixing stand, thereby preventing yarn waste while maintaining yarn holding stability.
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
Enables operators to easily and precisely monitor yarn tension during threading, reducing yarn waste and workload by providing real-time tension feedback, especially for low-tension yarns, and simplifying the apparatus structure.
Implementation Method 1
a tensiometer configured to measure the tension of at least one of the yarns, the at least one of the yarns being wound onto at least one of the bobbins
Implementation Method 2
While being sucked and held by a suction gun operated by an operator, the yarns spun out from the spinning apparatus are threaded to slits formed at end portions of the bobbins

AI summary
An object of the present invention is to enable an operator to easily grasp the tension of a yarn, which is sucked and held by a suction gun, at the time of yarn threading to a bobbin. A yarn winding apparatus 13 includes a bobbin holder 24 to which bobbins B aligned in a front-rear direction are attached, a traverse device 30, a contact roller 25, a supporting member 40 which supports the traverse device 30 and the contact roller 25, a base 20 which cantilevers a rear end portion of the bobbin holder 24 and that of the supporting member 40, a tensiometer 71 configured to measure the tension of a yarn Y threaded to at least one of the bobbins B, and a display unit 76 configured to display a tension value of the yarn Y having been measured by the tensiometer 71. The display unit 76 is provided at a position which is visually observable by the operator operating a suction gun 80 in order to perform yarn threading to the bobbins B.
