Packaging Line Image Clearance for Residual Product Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current manual line clearance processes in packaging equipment lines are inefficient, time-consuming, and prone to human error, often failing to detect residual products from previous runs, which can lead to incorrect packaging and potential safety issues.
Innovation Solution
An automated system utilizing image capturing devices installed along the packaging line to compare end-run images with control images, generating difference images and inspection reports to ensure thorough line clearance, reducing human intervention and improving detection accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual inspection processes are used for line clearance, then human operators can visually inspect the packaging line, but the process is time-consuming, inefficient, and subject to human error
Solution Approach 1:
The patent replaces manual mechanical inspection with an automated image-based inspection system. Image capturing devices automatically capture images of the packaging line, and image processing algorithms automatically analyze these images to detect residual products, eliminating the need for manual visual inspection and thereby reducing inspection time while improving reliability
Solution Approach 2:
The patent creates digital copies (images) of the packaging line using image capturing devices. These images serve as replicas that can be analyzed without physically inspecting the actual line, allowing for faster and more reliable detection of residual products while reducing the time required for manual inspection
2Difficulty of detecting and measuring
If manual inspection requires removal of shrouds, access covers and safety shields, then hidden areas become visible for inspection, but the process becomes more complex and time-consuming
Solution Approach 1:
The patent introduces image capturing devices as intermediaries that can view areas through or around shrouds, access covers, and safety shields without requiring their removal. These devices capture images that reveal hidden areas, eliminating the need for physical access while simplifying the inspection process
Solution Approach 2:
The patent transitions from physical-dimensional inspection (requiring physical access to hidden areas) to optical-dimensional inspection (using light and images). By capturing images through available openings or around obstacles, the system accesses hidden areas without physical intervention, reducing complexity while improving accessibility
3Productivity
If automated image capturing devices are installed throughout the packaging line, then detection accuracy and efficiency improve, but system complexity and installation cost increase
Solution Approach 1:
The patent employs image capturing devices that serve multiple functions: capturing images during normal operation, capturing images during line clearance, and providing visual records for analysis. This multi-functionality justifies the system complexity by delivering comprehensive inspection capabilities across different operational states
Solution Approach 2:
The patent implements a feedback loop where images are captured, analyzed, and used to determine whether line clearance is complete. The system provides visual feedback through difference images and inspection reports, enabling automated decision-making and improving inspection efficiency while managing system complexity through intelligent processing
