Textile Machine Level Display for Error Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional textile machines require frequent back-and-forth movement between central management devices and yarn processing units for monitoring and maintenance, leading to low operation efficiency and increased operator burden, as well as difficulties in promptly identifying and addressing errors in yarn processing units.
Innovation Solution
The textile machine incorporates a level display section and overall view display section on each yarn processing unit, allowing operators to easily assess operation levels and intuitively identify error locations through luminous sections and error occurrence rates, facilitating timely maintenance and improving production efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If operators check the monitor at the central management device to confirm the operation state of yarn processing units, then they can obtain information about the operation efficiency and error occurrence state, but they need to frequently move back and forth between the central management device and the yarn processing units, resulting in low operation efficiency and increased operator burden
Solution Approach 1:
The patent creates a visual copy of the operation state information by projecting images onto the yarn processing units themselves. The control device generates first images representing operation efficiency and second images representing error occurrence states, then projects these images directly onto the corresponding yarn processing units. This allows operators to view the information at the location of the equipment rather than returning to the central management device, eliminating frequent back-and-forth movement and reducing operator burden while maintaining access to comprehensive operation state information
Solution Approach 2:
The patent introduces a projection device as an intermediary between the central management device and the yarn processing units. The projection device receives operation state information from the central management device and transforms it into visual images that are projected onto the yarn processing units. This intermediary system enables operators to access detailed operation state information directly at the equipment location without physically returning to the central management device, thereby reducing movement time and operator burden
2Measurement precision
If operators perform prescribed operations from the central management device to extract and display specific yarn processing units on the monitor, then they can identify units needing maintenance, but they cannot realize decreases in operation efficiency until they perform these operations and check the monitor
Solution Approach 1:
The patent implements continuous monitoring and automatic projection of operation state information. The control device continuously acquires operation state information from all yarn processing units and automatically projects the corresponding images onto each unit. This continuous display eliminates the need for operators to perform repeated extraction operations to check on efficiency changes, allowing them to immediately notice decreases in operation efficiency at the equipment location and respond promptly
Solution Approach 2:
The system provides real-time visual feedback by projecting operation efficiency images directly onto the yarn processing units. When operation efficiency changes, the corresponding image on the equipment is updated immediately, providing continuous feedback to operators without requiring them to query the central management device. This enables operators to detect efficiency decreases at the moment they occur and take immediate corrective action
3Ease of operation
If error information is displayed only on the front panel of yarn processing units, then operators can immediately confirm errors without checking the monitor, but they cannot confirm the current operational state of units that are not experiencing errors
Solution Approach 1:
The patent makes the projection system universal by enabling it to display multiple types of information simultaneously. The same projection device that displays error occurrence information (second images) also displays operation efficiency information (first images). This multi-functional display system allows operators to obtain both error status and operational state information from a single source at the equipment location, eliminating the limitation of front panel displays that show only error information

AI summary
Each of a plurality of spinning units of a spinning machine includes a level display section, which displays an operation level that corresponds to an operation state of the spinning unit among a plurality of operation levels. The operation levels are classified such that a standard operation state, which is to be a standard, is located at a center. The standard operation state may be an average value of the operation states of the plurality of spinning units of the spinning machine or a given set value. Each of the plurality of spinning units further includes an operation panel, which displays an overall view illustrating an overall structure of the spinning unit. When an error has occurred in the spinning unit, the operation panel can carry out a display by identifying a section that corresponds to an error occurred section within the overall view.
