Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conveyor belt systems face challenges in adjusting the trough angle and automatically centering the belt when it drifts due to uneven loading, leading to mis-alignment issues.
Innovation Solution
An apparatus comprising a pivotable idler frame with angled wing struts and a center roller, along with a displaceable rod and securing mechanism, allows for adjustable trough angle settings and automatic self-centering by pivoting to maintain belt alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed trough configuration is used to contain material on the conveyor belt, then material containment is improved, but the ability to adjust the trough angle and automatically center the belt when it drifts is lost
Solution Approach 1:
The patent applies the dynamics principle by making the trough configuration adjustable rather than fixed. The angled idlers are mounted on an adjustable frame that can change the trough angle dynamically. Additionally, the self-aligning tracker mechanism automatically adjusts the belt position in real-time to correct drift, transforming a static system into a dynamic one that adapts to operating conditions while maintaining material containment
Solution Approach 2:
The patent implements parameter changes by allowing the trough angle to be adjusted through the movable angled idlers. The system can modify geometric parameters (trough angle) and operational parameters (belt position) to optimize performance. The self-aligning tracker continuously adjusts the belt's lateral position parameter to maintain proper alignment, enabling the system to adapt to varying loading conditions while preserving material containment
2Extent of automation
If self-aligning tracker systems are added to correct belt creep, then automatic centering is improved, but the complexity of the system increases
Solution Approach 1:
The patent applies self-service by designing a self-aligning tracker system that automatically corrects belt drift without external intervention. The angled idlers and adjustable frame work together to self-correct misalignment through mechanical feedback - when the belt drifts, the tracker automatically adjusts to restore proper alignment. This eliminates the need for complex external control systems, sensors, or actuators, achieving automatic centering through simple mechanical self-regulation that minimizes added complexity

AI summary
An apparatus and method for adjusting the trough angle of a conveyor belt transport mechanism and for automatically correcting for conveyor belt creep along the conveyor belt sides during belt operation. The apparatus and method are directed to an idler assembly that pivots through a high point over a base frame. The idler assembly includes a horizontal base strut and angled wing struts on each side of the base strut. Rotatably mounted on the horizontal base strut are a pair of parallel centered rollers that surround a centrally-located pivot point. Rotatably mounted on each angled wing strut is a respective conical-shaped wing roller wherein a lower end of the wing roller remains at a fixed distance from the wing element whereas the distance between the upper end and the angled wing strut is adjustable via a threaded rod using jam nuts to releasably secure the angled wing rollers at a desired angle. During belt operation, if conveyor belt creep occurs the idler assembly automatically pivots to correct and re-center the belt over the parallel-centered rollers.
