Automatic Winder Yarn Speed Control via RF Tag Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing yarn winding systems face challenges in optimizing automatic winder operation due to varying spinning machine specifications, particularly when these machines lack or have different communication standards, preventing effective transmission of spinning information and subsequent control of winding speed.
Innovation Solution
The automatic winder incorporates an input section for manual data entry and utilizes RF tags for managing yarn bobbin information, allowing for manual input of spinning information when communication is not possible, enabling the control device to adjust winding speed based on processing status and completion conditions, ensuring balanced operation with the spinning machine.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If wired or wireless communication is used to transmit spinning information, then automation and productivity are improved, but incompatibility with various spinning machine specifications prevents universal application
Solution Approach 1:
The patent introduces a medium (such as a paper tape or data carrier) as an intermediary to transfer spinning information from the spinning machine to the automatic winder. This medium acts as a universal interface that can be read by different winders regardless of the spinning machine's communication capabilities, thus resolving the incompatibility issue while maintaining automated information transfer.
Solution Approach 2:
The patent extracts the information transmission function from direct machine-to-machine communication and separates it into a standalone medium that carries the spinning information. This extracted medium can be independently produced and read by any winder equipped with the reading device, enabling universal compatibility across different machine specifications.
2Ease of operation
If automated communication systems are implemented, then operation control optimization is achieved, but device complexity increases due to communication requirements
Solution Approach 1:
The patent employs a simple, inexpensive medium (such as a paper tape or temporary data carrier) that is easily produced, distributed, and discarded after use. This disposable medium eliminates the need for complex, expensive communication infrastructure while still achieving automated information transfer and operation control optimization.
Solution Approach 2:
By introducing a simple intermediary medium rather than implementing complex direct communication systems, the patent achieves automated control optimization without the associated complexity. The medium serves as a bridge that requires minimal technological infrastructure on either end.
3Adaptability or versatility
If spinning information is not received due to communication limitations, then adaptability is maintained, but winding speed control optimization cannot be achieved
Solution Approach 1:
The medium serves as a universal intermediary that can be generated by any spinning machine regardless of its communication capabilities and can be read by any automatic winder. This enables spinning information to be transferred even from machines without communication functions, allowing winding speed control optimization to be achieved across all machine types.
Solution Approach 2:
The medium is designed to be universally compatible with all spinning machines and automatic winders, serving multiple functions: it carries spinning information, works with machines lacking communication functions, and can be read by any winder in the system. This universality ensures both adaptability and productivity improvement simultaneously.
