Multi-Paddle Sweeper Belt for Conveyor Sorting Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for moving packaged or small items from a conveyor surface to a delivery station have a high failure rate, requiring human intervention and resulting in delays and increased expenses.
Innovation Solution
A sweeper/sorter assembly comprising multiple paddle pieces linked to a plastic sweeper belt, positioned above the main conveyor, uses a motorized drive roller and sensors to control the movement of the paddles, allowing for reliable and precise diversion of items off the conveyor surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional methods are used to move items from conveyor surface, then the system is simple, but the reliability is low with high failure rate
Solution Approach 1:
The paddle assembly is divided into multiple individual paddle pieces (first paddle piece, second paddle piece, etc.) that are separately mounted on the sweeper belt. This segmentation allows each paddle to independently contact and guide items, improving sorting reliability while maintaining manageable device complexity through modular construction
Solution Approach 2:
The sweeper belt acts as an intermediary carrier that holds and positions multiple paddle pieces above the conveyor surface. This intermediary structure enables reliable item diversion by providing a stable platform for the paddles to contact items, resolving the contradiction between reliability and complexity
2Loss of time
If manual intervention is used for sorting failures, then the device complexity is low, but the loss of time increases due to delays
Solution Approach 1:
The multi-paddle sweeper assembly automatically performs item sorting and correction functions without requiring manual intervention. The paddles self-adjust to guide items onto the correct conveyor path, eliminating delays associated with human intervention and increasing the extent of automation in the sorting system
3Reliability
If simple conveyor surface contact is used, then the device complexity is low, but the reliability is insufficient for robust item movement
Solution Approach 1:
The paddle pieces are pre-positioned above the conveyor surface on the sweeper belt at optimal locations for item contact. This preliminary positioning ensures reliable item engagement before sorting is needed, allowing the system to robustly move items without requiring complex real-time adjustment mechanisms
