Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for separating flexibly rolled strip material struggle with precise measurement and positioning of sheet thickness profiles, leading to imprecise cutting and inability to identify and sort areas that do not meet thickness tolerances.
Innovation Solution
A system comprising a storage device, feed devices, length measuring devices, and a thickness gauge that continuously measure and compare the strip material's thickness and length to accurately position the separation point, allowing for precise identification and sorting of non-compliant areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual threading and constant length feeding is used, then the feed system is simple to operate, but the thickness profile positioning is imprecise and cannot meet positional tolerances
Solution Approach 1:
The system performs preliminary measurement of the thickness profile before cutting, stores the measured data, and uses this information to calculate and set the appropriate feed length in advance. This allows the cutting position to be precisely positioned relative to the thickness profile without requiring complex real-time adjustment mechanisms during feeding.
Solution Approach 2:
The system incorporates a thickness profile measurement device that continuously measures the thickness of the strip material, feeds this information back to a control unit, which then adjusts the feed length accordingly. This closed-loop feedback mechanism enables precise positioning of the thickness profile relative to the cutting edge while maintaining automated control.
2Measurement precision
If constant length feeding is used, then the feed process is simple, but areas not meeting thickness tolerances cannot be identified and sorted
Solution Approach 1:
The system performs preliminary measurement of the thickness profile and stores the measured data before the cutting process. This allows for identification of non-compliant areas in advance, enabling selective sorting and rejection of defective portions without slowing down the overall production process.
Solution Approach 2:
The system automatically identifies areas that do not meet thickness tolerances using the measured thickness profile data and autonomously determines the appropriate feed length to position these areas for sorting or rejection. This self-service capability eliminates the need for manual inspection while maintaining high processing speed.
3Manufacturing precision
If the thickness profile is not precisely positioned, then the cutting process is fast, but cutting precision and blank quality are compromised
Solution Approach 1:
The system performs preliminary measurement and storage of the thickness profile data, and pre-calculates the optimal feed length based on this data. This preparation is done in advance so that during the actual cutting process, the system can quickly position the blank without time-consuming adjustments, thereby maintaining high cutting precision while minimizing positioning time.
