Packaging Material Reference Marks for Opening Device Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging systems face issues with improper application of opening devices due to misalignment of packages on conveyor belts, leading to defective packages where the opening device is not correctly positioned or applied at all.
Innovation Solution
Incorporating detectable reference marks on the packaging material that align with creasing patterns, allowing an applying device equipped with a detecting unit to ensure accurate alignment and correct application of the opening device by comparing detected marks with a reference direction, and adjusting the package or applying element as necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If packages are conveyed on a conveyor belt for opening device application, then productivity is improved, but misalignment occurs leading to improper application of opening devices
Solution Approach 1:
The patent employs a sensor device (camera) that detects the position of packages and generates control signals to adjusting means. This feedback loop continuously monitors package position on the conveyor belt and automatically corrects misalignment by adjusting the conveyor belt position or the applying element position, ensuring precise opening device application while maintaining high productivity
Solution Approach 2:
The patent replaces manual alignment operations with an automated optical detection and mechanical adjustment system. The sensor device (optical field) detects package position, and the control system automatically adjusts the mechanical position of either the conveyor belt or applying element, eliminating the need for manual intervention and maintaining consistent precision at high speeds
2Manufacturing precision
If manual alignment is used to ensure correct opening device application, then manufacturing precision is improved, but productivity decreases
Solution Approach 1:
The system performs self-alignment through automated detection and adjustment. The sensor device automatically detects package position, the control system processes this information, and the adjusting means automatically corrects any misalignment without requiring manual intervention, enabling both high precision and high productivity
Solution Approach 2:
The system dynamically changes positional parameters of either the conveyor belt or applying element based on real-time detection. The control system adjusts the position coordinates automatically, transforming a static manual alignment process into a dynamic automated system that maintains precision while increasing speed
