Sound-Damped Conveyor Roller Assembly Without Pitch Change
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Material handling operations, particularly those involving conveyor rollers, produce significant noise and vibration due to ringing and rattling, which are undesirable for workers and others in proximity.
Innovation Solution
Conveyor rollers are equipped with sound dampers made of vibration-damping materials, and optionally feature tapered end connectors with plastic tips, ensuring the outer diameter remains unchanged by reducing a portion of the roller to accommodate the damper, thus maintaining the same pitch distance between rollers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If sound dampers are added to conveyor rollers, then noise and vibration are reduced, but the outer diameter of the roller increases
Solution Approach 1:
The roller is designed with a reduced outer diameter portion that accommodates the sound damper, while other portions maintain the original outer diameter. This local modification allows sound attenuation without increasing the overall roller dimensions, resolving the contradiction between noise reduction and maintaining compact size.
Solution Approach 2:
The sound damper is nested within the reduced outer diameter portion of the roller, fitting inside the space created by removing material from the roller body. This nesting approach allows the sound damper to be integrated without increasing the roller's external dimensions.
2Object-affected harmful factors
If sound dampers are added to conveyor rollers, then noise and vibration are reduced, but the pitch distance between rollers must be changed
Solution Approach 1:
By locally reducing the outer diameter of specific roller portions to accommodate sound dampers while maintaining the original outer diameter at other portions, the roller pitch distance remains unchanged. This allows sound attenuation without requiring changes to the conveyor system's pitch distance configuration.
3Volume of moving object
If the outer diameter of the roller is reduced to accommodate sound dampers, then the roller dimensions are maintained, but the roller structure is modified
Solution Approach 1:
The roller is divided into different portions with different outer diameters - a reduced outer diameter portion for mounting sound dampers and other portions maintaining the original diameter. This segmentation allows the roller to be manufactured in sections or with variable geometry, facilitating the integration of sound dampers without requiring complete roller redesign.

Function Achieved in This Case
The solution effectively reduces noise and vibration during conveyor operation without altering the pitch distance between rollers, making it suitable for both new and existing systems.
Implementation Method 1
a sound damping sleeve made of a sound damping material configured to attenuate vibration at the conveyor roller during operation of the conveyor roller assembly
Implementation Method 2
The tapered end portion has a plastic tip configured to reduce vibration between the conveyor roller and the conveyor roller assembly

AI summary
A sound attenuated conveyor roller assembly reduces the noise or vibration produced by the conveyor roller assembly during operation, and includes a conveyor roller having a cylindrical portion to which a sound damper may be coupled. The conveyor roller may include an unreduced outer surface and a reduced outer surface, in which the sound damper is disposed at the reduced outer surface such that an outer surface of the damper and the unreduced outer surface of the conveyor roller are located at substantially equal radial distances from a longitudinal axis of the conveyor roller. A tapered end connector having a tapered plastic tip may be coupled to each end of the conveyor roller to further reduce noise and vibration in the conveyor roller assembly.
