Elastic Blade Conveyor Roller for Quiet Inclined Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional metal rollers in conveyor devices generate noise and risk damaging objects, especially when used in inclined configurations due to collisions and angle discrepancies between conveying surfaces.
Innovation Solution
Conveying rollers with elastically deformable blade-shaped pieces around a core member, which absorb collision impacts and reduce noise, allowing for dense arrangement and varied lengths with shared components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a metal tube conveying roller is used, then the conveying roller has high strength and durability, but the hard surface may damage objects and generate noise when objects collide with it
Solution Approach 1:
The patent replaces the rigid metal tube with a flexible blade-shaped piece that has high elasticity. This flexible structure can deform when objects collide with it, absorbing impact energy and preventing damage to objects while reducing noise generation, thus resolving the contradiction between strength and harmful effects.
Solution Approach 2:
The patent changes the material parameter from rigid metal to elastic material, and changes the structural parameter from solid tube to thin blade shape. This parameter change enables the conveying roller to maintain conveying function while providing cushioning effect against collisions, eliminating damage and noise issues.
2Duration of action of stationary object
If a metal conveying roller with hard surface is used, then the conveying roller is durable, but collision noise is generated and objects may be damaged when delivered from inclined conveyor to horizontal conveyor
Solution Approach 1:
The elastic blade-shaped piece is designed in advance to provide cushioning protection. When objects are delivered from the inclined conveyor to the horizontal conveyor, the elastic material absorbs the impact energy before it can cause noise or damage, thus preventing harmful effects while maintaining durability.
3Object-affected harmful factors
If blade-shaped pieces are arranged densely around the core member, then the impact softening effect is enhanced, but the device complexity increases
Solution Approach 1:
The conveying roller is segmented into multiple blade-shaped pieces arranged around the core member. Each blade-shaped piece is independent and can deform to absorb impact. This segmentation provides enhanced impact softening effect while keeping each individual component simple, thus balancing performance and complexity.
