Vibration Device for Removing Pharmaceutical Containers from Trough
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices struggle to efficiently remove individual pharmaceutical containers from tub-shaped transport containers due to frictional forces and electrostatic attraction, leading to containers being removed with the transport container instead of remaining on the storage area.
Innovation Solution
A device with a plate-shaped discharge structure and a vibration generation system that stimulates the discharge structure to a vibration movement during the withdrawal process, helping to release individual containers from the transport container and ensure they remain on the storage area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If gravity-assisted removal is used to remove individual containers from the transport container, then the removal process is simple and automatic, but frictional forces and electrostatic attraction cause containers to be removed together with the transport container instead of remaining on the storage surface
Solution Approach 1:
The patent applies a vibration-generating device that excites the storage structure to oscillating movement during the removal process. This vibration is transferred to the transport container and individual containers, creating forces that overcome frictional and electrostatic attraction forces, thereby ensuring reliable detachment of containers from the transport container while maintaining automatic removal capability
2Ease of operation
If containers are stored loosely in the transport container, then handling and loading are easy, but individual containers cannot be reliably separated during automated removal
Solution Approach 1:
The vibration-generating device creates oscillating movement that acts on loosely stored containers during removal, providing the necessary force to overcome frictional and electrostatic forces even when containers are not tightly secured, thus maintaining both loading convenience and separation reliability
3Reliability
If vibration is applied to overcome frictional and electrostatic forces, then container detachment is reliable, but energy consumption increases
Solution Approach 1:
The vibration-generating device operates periodically during the removal process rather than continuously, applying vibration only when needed to overcome frictional and electrostatic forces during the critical detachment phase, thereby achieving reliable separation while minimizing overall energy consumption
