Crease Depth Indicator Stamping Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for checking the depth of crease lines in thermoplastics coated paperboard laminate materials are inconsistent and time-consuming, leading to inefficiencies in the production of container blanks.
Innovation Solution
A crease line forming device with a creasing cylinder and a stamping device having stamping portions at multiple levels, which marks the material with indicators away from the crease line to indicate its depth, allowing for continuous and reliable checking throughout the production process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual checking methods are used for crease line depth, then measurement can be performed, but the process is inconsistent and time-consuming
Solution Approach 1:
The patent replaces manual mechanical measurement methods with an automated optical measurement system. The apparatus uses a light source and sensor array to automatically detect and measure crease line depth, eliminating manual intervention and achieving consistent, rapid measurements throughout production.
Solution Approach 2:
The measurement system is integrated directly into the creasing apparatus, allowing the equipment to automatically monitor and verify its own output. The apparatus self-diagnoses crease depth quality without requiring separate quality control personnel or manual checking processes.
2Productivity
If continuous monitoring is implemented, then productivity is improved, but device complexity increases
Solution Approach 1:
The patent combines the measurement system with the existing creasing apparatus structure. The light source, sensor array, and processing unit are integrated into the mechanical assembly, allowing continuous monitoring without requiring a completely separate inspection system or significant additional complexity.
Solution Approach 2:
The apparatus serves multiple functions: it creates the crease lines through mechanical pressure and simultaneously monitors their depth through optical sensing. This multi-functionality allows continuous productivity improvement without proportionally increasing device complexity, as the same structure performs both forming and inspection tasks.
