Inspection Machine Turntable Dynamics for Liquid Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inspection machines face challenges in accurately identifying foreign particles within liquids in containers due to turbulence generated by high-speed rotation and axis misalignment, which hinders inspection and increases maintenance and downtime.
Innovation Solution
An inspection machine with a turntable and dragging means that allows containers to rotate idly around a vertical axis, minimizing turbulence by supporting the container at both ends and using optical means for precise inspection, including video cameras, and adjustable dragging mechanisms to accommodate different container sizes and shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the container is rotated at high speed for inspection, then the inspection speed increases, but turbulence is generated within the liquid which hinders or prevents correct inspection
Solution Approach 1:
The patent applies dynamics by making the support plate movable between a first position (for high-speed rotation and quick inspection) and a second position (for stable, low-speed inspection). This dynamic adjustment allows the system to optimize between inspection speed and liquid stability based on the inspection stage, resolving the contradiction between productivity and turbulence prevention.
2Ease of operation
If the container neck has axis misalignment with the rest of the container, then the container can be easily positioned, but turbulence is induced or accentuated during rotation
Solution Approach 1:
The support plate is made movable to dynamically adjust the container's rotational characteristics. By transitioning between positions, the system can accommodate initial positioning tolerances while minimizing turbulence during the critical inspection phase, thus resolving the contradiction between ease of positioning and turbulence prevention.
3Device complexity
If a single support plate is used to hold the container, then the device structure is simple, but the container may be damaged by broken glass pieces and maintenance operations increase
Solution Approach 1:
The patent segments the support system into multiple independent support plates instead of using a single support plate. This segmentation allows individual plates to be positioned at different locations, providing distributed support that protects against container damage while maintaining relatively simple device structure. The modular approach also facilitates easier maintenance.
4Device complexity
If the support plate is fixed in position, then the device structure is simple, but it cannot accommodate different container sizes and shapes
Solution Approach 1:
The support plate is designed to be movable rather than fixed, enabling dynamic adjustment to accommodate different container sizes and shapes. This dynamic capability provides adaptability while maintaining relatively simple device structure, resolving the contradiction between structural simplicity and versatility.
