Vial Autoloader Horizontal Loading Automation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual loading of vials into analyzers is labor-intensive and time-consuming, especially when handling large numbers of samples.
Innovation Solution
An autoloader system that includes a carriage assembly, a lifter, a deck, a vial carousel, and a controller, which automates the loading and unloading of vials into an analyzer in a horizontal orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If vials are manually loaded into the analyzer one at a time, then the operation is simple and direct, but the labor intensity and time consumption increase significantly when handling large numbers of samples
Solution Approach 1:
The system segments the batch of vials into individual units that can be independently loaded into the analyzer. The deck is divided into multiple stations, each capable of holding and presenting a single vial to the analyzer, enabling automated sequential processing while maintaining operational simplicity.
Solution Approach 2:
The autoloader system performs self-service by automatically loading vials into the analyzer without requiring manual intervention for each sample. The carousel rotates to present vials, the lifter positions them, and the carriage assembly loads them automatically, freeing the operator from repetitive manual loading tasks.
2Productivity
If an automated autoloader system is implemented, then the productivity and efficiency increase, but the device complexity increases
Solution Approach 1:
The system merges multiple functions into integrated components: the deck serves as both a support structure and a positioning mechanism, the carousel combines rotation and vial presentation functions, and the lifter integrates vertical movement with horizontal positioning. This consolidation achieves automation while controlling overall system complexity.
Solution Approach 2:
The carriage assembly serves multiple functions: it loads vials into the analyzer, positions them correctly, and retrieves them after analysis. The deck stations serve both as vial holders and as positioning references for the carousel rotation, reducing the need for separate dedicated components.
3Speed
If the vial carrier support is lowered to load vials, then the loading speed increases, but the risk of vial misalignment or damage increases
Solution Approach 1:
The system uses sensors to detect vial presence and position on the deck stations before the loading operation. This feedback allows the controller to verify correct positioning and adjust the carousel rotation or lifter movement if misalignment is detected, ensuring reliable loading while maintaining speed.
Solution Approach 2:
The carousel rotates to position the desired vial at the loading station before the lifter lowers the carrier support. This preliminary positioning action ensures the vial is correctly aligned with the analyzer entrance, preventing misalignment or damage during the rapid loading operation.

AI summary
An autoloader is disclosed for staging samples in vials to be loaded automatically into an analyzer such as a moisture analyzer for moisture analysis. The analyzer uses vials to hold small amounts of sample materials. The autoloader holds the vials in a horizontal orientation for delivery to and removal from the analyzer.
