Conveyor Belt Curved Path Guide Roll Arrangement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conveyor means with chain link belts experience polygon effects, radial forces, and friction forces on curved path sections, leading to uneven and forceful movement, making it difficult to detect and replace defective rolls and maintain smooth operation.
Innovation Solution
An endless conveyor belt with a curved path section featuring an inner guiding and rolls interacting with each chain link, along with adjustable roll positions and curvature-matched chain link faces, reduces polygon effects and friction, allowing for easy roll replacement and maintenance, and supports for articles to ensure reliable transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rolls are positioned in between the slats and the support at the moving endless conveyor belt, then smooth and constant movement of the conveyor means is ensured, but defective rolls cannot be detected easily nor can single rolls be removed easily and quickly and attached and/or replaced respectively
Solution Approach 1:
The conveyor belt is divided into modular chain links with individual guide rolls that can be independently accessed and replaced. Each chain link contains its own guide roll mounted on a mounting element, allowing segmented maintenance without stopping the entire conveyor system.
Solution Approach 2:
Instead of mounting rolls on the moving conveyor belt components, the guide rolls are mounted on the stationary support structure. This inversion allows rolls to be easily accessed and replaced while the conveyor belt moves continuously, resolving the contradiction between maintaining smooth movement and enabling easy repair.
2Adaptability or versatility
If an endless conveyor belt with curved path section is used, then articles can be transported along curved paths, but polygon effects and radial forces impact on the chain links, jeopardizing smooth movement
Solution Approach 1:
The chain links are designed with curved interaction faces that match the curvature of the guide rolls. This curvature matching reduces polygon effects and radial forces by ensuring continuous contact between the chain links and guide rolls throughout the curved path section, maintaining smooth movement while enabling curved path transport.
Solution Approach 2:
The interaction faces of the chain links are given specific curvature parameters that correspond to the guide roll curvature. This parameter optimization minimizes harmful radial forces and polygon effects, allowing the conveyor to handle curved paths reliably.
3Productivity
If friction reduction measures are implemented on curved path sections, then movement efficiency is improved, but device complexity increases
Solution Approach 1:
By curving the interaction faces of the chain links to match the guide rolls, the design reduces friction and polygon effects through geometric optimization rather than adding complex mechanical components. This maintains movement efficiency while avoiding increased device complexity.
Solution Approach 2:
The curvature parameters of the chain link faces are optimized to minimize friction and radial forces on curved paths. This parameter-based solution improves productivity through efficient geometry rather than through additional complex mechanisms.
