Belt Transport Device Edge Lubrication and Shift Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing belt transport devices face issues with lubricant application and recovery at edge portions, leading to inefficiencies and potential damage during walking phenomena, where the belt shifts towards the edge, resulting in insufficient lubrication and abrasion.
Innovation Solution
A belt transport device with an endless belt, stretchers, a corrector to displace the belt, and a lubricant applicator that applies lubricant to the inner surface at edge portions when the belt shifts, ensuring consistent lubrication and preventing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the belt shifts toward the edge portion during operation, then the belt maintains continuous movement, but lubrication at the edge portion becomes insufficient causing abrasion and potential damage
Solution Approach 1:
The lubricant applicator is positioned to apply lubricant in advance to the edge portion of the belt before the belt shifts completely to that edge. This preliminary lubrication ensures that when the belt does shift, the edge portion is already lubricated, preventing abrasion and damage while maintaining continuous belt operation.
Solution Approach 2:
A lubricant applicator serves as an intermediary component between the lubricant source and the belt edge portion. This applicator delivers lubricant precisely to the edge portion where it is needed, mediating the lubrication process and ensuring adequate lubrication even when the belt shifts to the edge.
2Reliability
If lubricant is applied continuously along the entire belt, then the belt is well-lubricated, but lubricant is wasted and cannot be recovered efficiently
Solution Approach 1:
Instead of applying lubricant uniformly along the entire belt, the lubricant applicator is designed to apply lubricant locally only at the edge portion where the belt shifts. This localized application ensures adequate lubrication at the critical area while minimizing lubricant waste and improving recovery efficiency.
Solution Approach 2:
The lubricant applicator is positioned to allow lubricant to be applied to the belt edge and then recovered from there. This enables the system to discard excess lubricant that would otherwise be wasted and recover the lubricant that is transferred to the belt, improving overall lubricant efficiency.

Function Achieved in This Case
The solution effectively addresses the inefficiencies and damage caused by belt shifting by ensuring lubricant application at edge portions, reducing abrasion and maintaining belt performance.
Implementation Method 1
a lubricant applicator that applies a lubricant to an inner surface of the belt at the edge portion of the belt in the axial direction when the belt has shifted toward the edge portion in the axial direction

AI summary
A belt transport device includes an endless belt, multiple stretchers that stretch the belt, a corrector that displaces one of the multiple stretchers to correct a shift of the belt toward an edge portion of the belt in an axial direction of the belt, and a lubricant applicator that applies a lubricant to an inner surface of the belt at the edge portion of the belt in the axial direction when the belt has shifted toward the edge portion in the axial direction.
