Spinning Machine Additive Supply Abnormality Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spinning machines lack effective detection and control mechanisms for abnormalities in additive supplying devices, leading to inconsistent yarn quality due to incomplete or excessive additive supply.
Innovation Solution
A spinning machine equipped with a draft device, spinning device, winding device, additive supplying device, first detecting section, and control device that detects additive supply state and determines abnormalities, allowing for proactive control measures such as halting or resuming operations to maintain yarn quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If an additive supplying device is used to supply additive to the spinning device, then the quality of yarn can be improved through proper additive application, but if the additive supplying device experiences abnormality, then defective yarn is produced with mixed portions supplied and not supplied with additive
Solution Approach 1:
A detection device is installed in the additive supplying device to detect the supply state of additive. The control device receives detection signals and determines presence or absence of abnormality, enabling real-time feedback control to prevent defective yarn production when abnormalities occur
Solution Approach 2:
The control device prohibits the spinning operation before defective yarn can be formed by detecting additive supply abnormalities in advance. When abnormality is detected, the control device stops the spinning device before it produces defective yarn, preventing quality issues rather than correcting them after occurrence
2Productivity
If the spinning device operates continuously to maintain productivity, then production efficiency is improved, but if additive supply abnormality occurs during operation, then defective yarn is produced
Solution Approach 1:
The detection device continuously monitors additive supply state during spinning operation. When abnormality is detected, the control device immediately stops the spinning device, providing real-time feedback control that maintains yarn quality consistency while allowing continuous operation under normal conditions
Solution Approach 2:
The system performs self-diagnosis through the detection device that monitors its own additive supply state. The control device automatically determines abnormality and controls the spinning device accordingly, enabling the system to self-regulate and prevent defective yarn production without external intervention
