Capsule Inspection System Using Roller Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing capsule inspection systems require frequent replacement of rotation drums and jigs due to varying capsule sizes and shapes, leading to inefficiencies and increased costs, as they need multiple components to inspect capsules from different angles.
Innovation Solution
A capsule inspection system with rollers connected to form a separation gap, allowing capsules to be self-rotated and aligned horizontally, enabling 360-degree exposure for inspection with a single vision system and eliminating the need for multiple rotation drums and vision systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple rotation drums and jigs are used to inspect capsules from different angles, then inspection completeness is improved, but device complexity and cost increase
Solution Approach 1:
A single rotation drum is designed to perform multiple functions: holding capsules, rotating them to different angles, and positioning them for inspection from multiple directions. This eliminates the need for separate rotation drums and jigs for different inspection angles, reducing device complexity while maintaining inspection completeness
Solution Approach 2:
Multiple inspection functions that previously required separate devices are merged into a single integrated system. The rotation drum combines capsule holding, rotation, and positioning capabilities, while a single vision system captures images from multiple angles through coordinated rotation, reducing the overall number of components
2Measurement precision
If rotation drums and jigs are replaced for each capsule model, then inspection accuracy is improved, but productivity and efficiency deteriorate
Solution Approach 1:
The rotation drum is designed with universal compatibility to accommodate different capsule models without requiring replacement. It can hold and rotate various capsule types while maintaining proper positioning for inspection, ensuring both inspection accuracy and continuous productivity across different capsule varieties
Solution Approach 2:
The system uses dynamic adjustment capabilities where the rotation drum can be programmed to rotate to specific angles and positions based on the capsule model being inspected. This allows the same physical device to adapt to different capsule types while maintaining inspection accuracy, eliminating the need for physical replacement of components
3Speed
If capsules are randomly introduced without alignment, then handling speed is improved, but inspection quality deteriorates
Solution Approach 1:
The system performs preliminary alignment of capsules during the rotation process before inspection. As capsules are rotated to the inspection position, they are automatically oriented correctly, ensuring that the vision system receives properly positioned capsules for high-quality inspection without sacrificing handling speed
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution allows for efficient inspection of various capsule types without replacing jigs or rotation drums, improving accuracy and speed by enabling all-directional inspection of randomly introduced capsules using a single vision system and reducing equipment costs.
Implementation Method 1
rollers are consecutively connected to each other with a gap between the rollers to allow introduced capsules to be seated in a separation gap... when the moving part repeatedly performs going/stopping, shapes of the capsules that are self-rotated as each of the rollers is rotated/stopped may be exposed

AI summary
The present invention relates to an inspection system for confirming whether a capsule is defective and, more particularly, a large quantity of capsules flowing in from the outside is randomly supplied to a moving part by means of a hopper part, the moving part transfers, to a discharge part by means of a plurality of rollers, the large quantity of capsules fed by means of the hopper part so that a controller can distinguish between the good-quality and defective capsules on the basis of an image captured by means of a vision part and discharge same, a gap is formed between the rollers so that the plurality of fed capsules are randomly loaded and horizontally aligned in the gap, and the vision part can capture still images of the rotating capsules that are horizontally aligned and loaded in the gap, while the rollers rotate/stop through a driving part according to the repeated going/stopping of the moving part.
