Yarn Winding Machine Malfunction Indication and Restart Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing yarn winding machines lack clear indication of whether a malfunction should be handled by an average operator or an advanced operator, leading to inappropriate maintenance operations and decreased productivity due to mismatches between required and performed operations.
Innovation Solution
The yarn winding machine incorporates separate abnormal-state-indicating and restarting sections to distinguish between malfunctions caused by the yarn supply source and the winding bobbin, allowing operators to accurately determine the required actions and prevent mismatches in operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If separate images indicating malfunction positions are provided separately from malfunction fixing buttons, then the yarn winding machine can indicate malfunction positions, but operators cannot accurately match the required operation with the performed operation
Solution Approach 1:
The patent combines the malfunction position indication function and the malfunction fixing function into a single integrated button. Each button simultaneously displays the malfunction position (through illumination or display) and serves as the fixing button for that specific malfunction. This merging eliminates the separation between indication and action, ensuring operators can easily identify and correct the appropriate malfunction without confusion between different components.
2Loss of information
If the yarn winding machine provides malfunction position indication, then operators can identify malfunction locations, but operators still cannot determine whether they should handle the malfunction or ask advanced operators
Solution Approach 1:
The patent segments the malfunction types into distinct categories, each represented by a separate integrated button. By providing separate buttons for different malfunction positions and types, the system enables operators to clearly identify not only the location but also the specific type of malfunction. This segmentation allows operators to determine their own capability to handle the malfunction or recognize when advanced operator assistance is needed, improving decision-making reliability.
3Loss of information
If the yarn winding machine uses separate indication images and separate fixing buttons, then the machine can provide malfunction information, but productivity decreases due to operator confusion
Solution Approach 1:
The patent merges the indication function and the fixing function into a single integrated button for each malfunction type. This eliminates the need for operators to search for separate fixing buttons after identifying malfunction positions through separate images. The integrated design streamlines the maintenance process, reduces operational errors, and minimizes downtime, thereby improving overall productivity while maintaining clear malfunction position indication.

AI summary
A yarn winding machine (2) includes a first abnormal-state-indicating and restarting section (23b,60) and a second abnormal-state-indicating and restarting section (23a,60). The first abnormal-state-indicating and restarting section (23b,60) is switched from a normal state indication to an abnormal state indication at least when a malfunction has been caused by a yarn supply source (B), and is switched to the normal state indication and switches the yarn winding machine (2) from a stopped state to an operating state when being operated during the abnormal state indication. The second abnormal-state-indicating and restarting section (23a,60) is switched from a normal state indication to an abnormal state indication at least when a malfunction has been caused by a winding bobbin (Bf), and is switched to the normal state indication and switches the yarn winding machine (2) from the stopped state to the operating state when being operated during the abnormal state indication. By using the above-described structure, a mismatch between the required operation to be performed to the yarn winding machine to fix a malfunction and the operation performed to the yarn winding machine is prevented. Accordingly productivity of the yarn winding machine is improved.
