Conveying Device Swing Support for Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing conveying devices face issues with holding unit inclination and shaking during elevating operations due to variable thickness errors or dimensional errors in belts and rolling elements, leading to instability and reduced transfer efficiency, especially with longer elevating strokes.
Innovation Solution
The conveying device incorporates a swing support unit that allows the holding unit to pivot, with belt members connected to support the holding unit above its centroid, and an inclination detection unit to control the elevating mechanism, ensuring the holding unit remains horizontal and stable by guiding it with interlocking guide units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the holding unit is hung and supported by multiple belts connected to rolling elements, then the elevating operation can be performed, but variable thickness errors in belts or dimensional errors in rolling elements cause the holding unit to become inclined
Solution Approach 1:
The support member is designed to be pivotable relative to the holding unit, allowing dynamic adjustment to compensate for belt thickness variations and rolling element dimensional errors. This pivoting capability enables the system to self-correct inclination issues during operation, maintaining proper holding unit orientation despite manufacturing tolerances in the belts and rolling elements.
2Ease of operation
If the holding unit is supported by telescopic elevating mechanisms, then the elevating operation can be performed, but adjustment is required to synchronously operate the mechanisms and the overall weight increases
Solution Approach 1:
The invention merges the support and guiding functions into a single integrated support member structure. This unified design eliminates the need for separate telescopic elevating mechanisms, thereby removing the synchronization adjustment requirement and reducing the overall device weight while maintaining the elevating capability.
3Ease of operation
If the holding unit is supported at three points with a swing arm, then the elevating operation can be performed, but vibrations increase and stabilization time increases
Solution Approach 1:
The invention extracts and eliminates the swing arm component from the system, replacing it with a direct pivotable support member connection. This removal of the swing arm intermediate structure reduces vibration amplification and eliminates the stabilization delay associated with swing arm oscillation, while maintaining the necessary elevating functionality.
