Handling System Tracking Range Segmentation for Conveyed Articles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handling systems for conveyed articles are inefficient in processing information due to overlapping processing of measurement values and unnecessary load, especially when multiple articles are captured in a single image, making it difficult to provide additional information like the type of articles and increasing processing load.
Innovation Solution
A handling system comprising a conveying part, a visual sensor for imaging and detecting article positions, a movement detecting part for tracking range monitoring, an article selecting part, and a controlling part that efficiently processes and selects articles based on predetermined conditions, including additional information like article type, to optimize article handling and reduce processing load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the system uniformly manages position data of all workpieces and searches for data related to position data, then the system can specify workpiece positions, but the processing load increases unnecessarily due to overlapping processing of measurement values
Solution Approach 1:
The patent divides the carrying part into multiple tracking ranges in the conveyance direction and manages position data separately for each tracking range. This segmentation allows the system to process only relevant workpieces within each range rather than uniformly processing all workpieces, thereby reducing overlapping processing and improving information processing efficiency while maintaining position specification accuracy.
2Reliability
If the system processes position data for all workpieces including those upstream from the robot, then complete workpiece tracking is achieved, but the processing load increases unnecessarily
Solution Approach 1:
The patent applies local quality by focusing processing resources on workpieces within the detection area and relevant tracking ranges rather than uniformly processing all workpieces throughout the entire carrying part. This localized approach maintains reliable tracking for workpieces that need handling while reducing unnecessary processing load for workpieces outside the relevant range.
3Productivity
If the system captures multiple workpieces in a single image, then imaging efficiency is improved, but the same measurement value is retrieved and specified for each workpiece causing overlapping processing
Solution Approach 1:
The patent segments the carrying part into multiple tracking ranges and assigns separate position data management to each range. When multiple workpieces are captured in a single image, the system can distinguish and process position data for each workpiece within their respective tracking ranges, avoiding the problem of retrieving and specifying the same measurement value for all workpieces and reducing overlapping processing complexity.
