Solution Overview
Problem
Current cork plank sorting by thickness is manual, skill-dependent, and error-prone, with low productivity and profitability due to the lack of automated mechanical devices in the cork industry.
Innovation Solution
A cork plank automatic ejection module with a frame comprising a cork plank inlet and outlets, a displacing extracting member along non-coplanar planes, and a position sensor, integrated with a cork plank conveyor system and automatic thickness reading device connected to a central processing unit for selective ejection based on thickness ranges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual sorting by operators is used, then flexibility and adaptability are maintained, but productivity is low and errors occur
Solution Approach 1:
The patent replaces manual mechanical sorting operations with an automated optical-mechanical system. Cameras capture images of cork planks, computer means analyze the images to determine thickness and roughness, and mechanical ejectors automatically sort planks into different compartments based on measured parameters, eliminating manual labor while maintaining sorting accuracy.
Solution Approach 2:
The system enables self-service sorting where the cork planks themselves are measured and sorted automatically without human intervention. The optical sensors detect plank characteristics, the computer processes the data, and the mechanical system executes sorting, creating a self-contained automated sorting process that improves productivity while reducing manual operation.
2Measurement precision
If manual sorting is used, then operator skill can be adapted, but measurement precision and reliability are compromised
Solution Approach 1:
The patent replaces subjective human judgment with objective optical measurement systems. Cameras capture precise images of cork planks, and computer algorithms consistently analyze these images to determine thickness and roughness, eliminating variability in human perception and ensuring consistent, reliable measurements across all planks.
Solution Approach 2:
The system incorporates feedback mechanisms where the computer continuously analyzes image data from cameras, compares measurements against predetermined specifications, and adjusts sorting decisions accordingly. This closed-loop control ensures high measurement precision and reliable consistent sorting by constantly monitoring and responding to actual plank characteristics.
3Productivity
If automated devices are introduced, then productivity increases, but device complexity increases
Solution Approach 1:
The patent divides the sorting system into distinct functional segments: image capture cameras, computer processing means for analysis, and separate mechanical ejector mechanisms for each sorting compartment. This segmentation allows each component to be optimized independently and simplifies maintenance while maintaining high overall productivity through coordinated operation of modular units.
Solution Approach 2:
The system employs universal components that perform multiple functions: the camera system captures images for both thickness and roughness analysis, the computer processing means handles multiple plank characteristics simultaneously, and the mechanical ejectors can sort planks into different compartments based on various criteria, reducing overall system complexity through multi-functional elements.
