Solution Overview
Problem
Current thread accumulation devices in the textile industry face challenges with high installation costs, difficulty in achieving homogeneous thread accumulation, and safety risks due to increased speeds, which result in inefficient thread handling and potential operator hazards.
Innovation Solution
A thread accumulation device with a carriage equipped to monitor its movement and support the thread spiral, allowing for parallel guidance along the discharge chute, which reduces vertical space occupation and enables homogeneous accumulation, and incorporates automatic tension adjustment to prevent operator intervention and safety risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the discharge chute is extended to increase accumulation capacity, then the accumulation capacity is improved, but the vertical space occupied increases significantly
Solution Approach 1:
The discharge chute is configured with a horizontal extension rather than vertical stacking, transforming the accumulation capacity expansion from a vertical dimension to a horizontal dimension. This allows the chute to extend in the horizontal direction while maintaining a compact vertical profile, effectively decoupling accumulation capacity from vertical space occupation.
2Ease of operation
If the discharge chute is inclined to allow effective carriage action, then the thread tension control is improved, but the vertical space occupied increases
Solution Approach 1:
The discharge chute incorporates a localized inclined section only where the carriage needs to exert its braking and monitoring action on the thread strand. The rest of the chute maintains a horizontal or minimal slope configuration. This localized inclination provides the necessary thread tension control functionality while minimizing the overall vertical space requirement of the entire discharge chute structure.
3Ease of operation
If the carriage is weighted to brake and monitor the strand, then the thread spiral tension is improved, but the device complexity increases
Solution Approach 1:
The carriage is equipped with an automatic weight adjustment mechanism that allows it to self-regulate the braking force and monitoring pressure on the thread strand based on operational conditions. This eliminates the need for manual weight adjustments by operators and reduces the complexity of the overall system by making the tension control self-adjusting rather than requiring external intervention.
4Quantity of substance
If the discharge chute is extended for significant accumulation, then the accumulation capacity is improved, but elevated access means are required increasing installation costs
Solution Approach 1:
The discharge chute extends horizontally to provide significant accumulation capacity without requiring vertical elevation. This horizontal configuration allows operators to access and service the entire length of the chute at ground level, eliminating the need for expensive elevated walkways, platforms, or other access infrastructure that would be required if the chute extended vertically.
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 solution allows for efficient, homogeneous thread accumulation and easy thread take-up, reducing vertical space requirements and enhancing operator safety by enabling continuous, automatic tension monitoring and adjustment, thus optimizing the thread handling process.
Implementation Method 1
this carriage can be weighted in order to produce a support force on the head of the strand, at the outlet of the thread spiral, essentially to brake and monitor the strand during unwinding
Implementation Method 2
the thread strand moves into the discharge chute by sliding into the latter and, starting from a certain length and based on the thread, the thus produced friction action on the wall of the discharge chute becomes significant, which, in combination with the action of the carriage, leads to an increase in the density of the strand
