Yarn Texturing Machine Conversion With Pulley-Belt Drive
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing high and medium tenacity yarn texturing machines are inherently incompatible, requiring separate maintenance and incapable of producing both yarn types on a single apparatus due to differences in drive systems and oil absorption issues.
Innovation Solution
A conversion apparatus comprising a pulley system with a bracket, bearing unit, and cover, allowing attachment of a pin spindle texturing unit to a medium tenacity machine, utilizing an endless drive belt to connect to the existing motor, enabling conversion between machine types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single endless drive belt is used to power multiple pin spindle texturing units, then high tenacity yarn production is achieved, but the entire machine must be stopped for maintenance or yarn changes
Solution Approach 1:
The patent segments the drive system by replacing the single endless drive belt with individual drive belts for each pin spindle texturing unit. Each unit can now be maintained or adjusted independently without stopping the entire machine, while still maintaining the capability to produce high tenacity yarn through the pin spindle mechanism.
2Adaptability or versatility
If friction texturing apparatus is used, then medium tenacity yarn production is achieved, but high tenacity yarn production becomes impossible due to oil absorption by friction discs
Solution Approach 1:
The patent creates a universal texturing machine that can accommodate both friction texturing units and pin spindle texturing units on the same platform. The machine frame and drive system are designed to accept different texturing unit types, allowing the facility to produce both medium tenacity yarn (using friction discs) and high tenacity yarn (using pin spindles) without oil absorption issues interfering with high tenacity production.
3Reliability
If medium tenacity and high tenacity machines are kept separate, then each machine type operates optimally, but manufacturing efficiency decreases due to incompatible drive systems
Solution Approach 1:
The patent merges the previously separate medium tenacity and high tenacity texturing machines into a single hybrid machine. The machine frame accommodates both friction texturing units (for medium tenacity yarn) and pin spindle texturing units (for high tenacity yarn), with a unified drive system that can power different unit types. This reduces the number of separate machines needed while maintaining optimal operation characteristics for each yarn type.

AI summary
There is provided apparatus for converting between a medium tenacity yarn producing machine and a high tenacity yarn producing machine. The apparatus comprises a pulley (40) adapted to be driven by a motor after removal of a multi-disc texturing unit (11) of the medium tenacity yarn producing machine from a casing (14). A bracket (30) is securable to the casing (14) with the pulley (40) mounted to the bracket (30) by means of a bearing unit (46) such that the pulley (40) is rotatable relative to the bracket (30). The bracket (30) has one or more mounting points to which a pin spindle texturing unit (20) of the high tenacity yarn producing machine can be attached. An endless drive belt (50) connects the pulley to a drive shaft (24) of the pin spindle texturing unit (20). The diameter of the pulley (40) is greater than the diameter of the drive shaft (24), and the diameter of a drive disc (23) of the pin spindle texturing unit (20) is larger than the diameter of a disc pin spindle (21) of the unit (20).
