Carousel Conveyor Center Drive Module Wear Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current carousel conveyor systems with corner drive assemblies are inefficient and prone to wear due to the engagement of drive wheels with the side edge of the conveyor chain, leading to wear on both the chain and the drive components.
Innovation Solution
A center drive module with a drive motor, sprocket wheels engaging the conveyor chain from below, and guide rollers with alignment slots to restrict vertical movement, reducing wear and enhancing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If drive wheels frictionally engage the side edge of the conveyor chain to impart driven movement, then the conveyor chain can be moved along the conveyor path, but wear occurs on both the chain and the drive components
Solution Approach 1:
Instead of driving the conveyor chain from the side as in conventional corner drive assemblies, this invention inverts the drive approach by engaging the chain from below using sprocket wheels. The sprocket wheels engage the bottom surface of the chain, reversing the traditional drive direction and eliminating side-edge wear while providing more reliable driven movement.
Solution Approach 2:
The invention introduces guide rollers with alignment slots as intermediary elements between the sprocket wheels and the conveyor chain. These guide rollers engage the sides of the chain and prevent vertical movement, mediating the force transmission to ensure the chain moves only in the longitudinal direction without upward displacement, thereby reducing wear on both the chain and drive components.
2Productivity
If sprocket wheels engage the conveyor chain from below to drive it, then longitudinal movement is achieved, but upward force causes vertical movement of the chain
Solution Approach 1:
Guide rollers with alignment slots serve as intermediary elements that engage the sides of the conveyor chain. These rollers prevent vertical movement by providing lateral support, mediating the force transmission from the sprocket wheels to ensure the chain moves only in the longitudinal direction without upward displacement.
Solution Approach 2:
The guide rollers apply localized constraint forces at specific points along the chain through the alignment slots. This local quality approach ensures that vertical movement is prevented only where necessary (at the guide roller contact points) while allowing free longitudinal movement, maintaining chain stability without compromising productivity.
3Stability of the object's composition
If flanges are formed on the support frame to prevent upward movement of the chain, then vertical movement is restricted, but wear occurs on the flanges and chain
Solution Approach 1:
Instead of using stationary flanges on the support frame to prevent upward movement, this invention inverts the approach by using rotating guide rollers that actively engage the chain. The guide rollers rotate with the chain movement, distributing wear across the roller surface rather than concentrating it on fixed flanges, thereby improving reliability while maintaining vertical position stability.
Solution Approach 2:
The guide rollers are designed to rotate dynamically with the chain movement, transforming the static wear interface of flanges into a dynamic rolling contact. This dynamic approach allows the guide rollers to self-renew their contact surface through rotation, significantly reducing wear on both the guide rollers and the conveyor chain while maintaining effective vertical position restriction.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The center drive module effectively imparts longitudinal movement to the conveyor chain while preventing vertical movement, thereby reducing wear and improving the durability of both the conveyor chain and the drive module.
Implementation Method 1
Outer teeth of the sprocket wheel engage drive lugs formed on the bottom surface of the conveyor chain such that the sprocket wheel causes the conveyor chain to move along the longitudinal conveyor path
Implementation Method 2
The interaction between the outer flange on each of the guide rollers and the alignment slots formed in the conveyor chain prevent the conveyor chain from moving in a direction perpendicular to the longitudinal direction of chain movement
Implementation Method 3
Each of the guide rollers includes a circular outer flange that is received within an alignment slot formed on each side of the conveyor chain

AI summary
A center drive module for use with a carousel conveyor that includes a continuous loop conveyor chain. The drive module includes a drive motor that rotates one or more sprocket wheels that each engage drive lugs formed on the bottom surface the conveyor chain to move the conveyor chain along the support frame. The drive module includes a pair of guide rollers positioned on opposite sides of the sprocket wheel. The guide rollers engage the conveyor chain and rotate upon the movement of the conveyor chain. Each of the guide wheels resists vertical movement of the conveyor chain caused by the rotating sprocket wheels.
