Sample Holder Transfer Mechanism to Prevent Tipping During Lift
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sample lifting and lowering mechanisms risk tipping over small sample holders due to parallel rotation and vertical movement operations, leading to positional deviations.
Innovation Solution
A sample lifting and lowering mechanism that rotates the sample holder loading unit after completing vertical operations, using a rotary shaft to minimize positional deviations and prevent tipping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the loading unit rotates around a fulcrum while the fulcrum simultaneously moves vertically, then the article can be carried out efficiently, but the positional relationship between the loading unit and the conveyance line deviates, causing the sample holder to tip over
Solution Approach 1:
The patent divides the carry-out operation into two separate sequential phases: first the loading unit rotates around a stationary fulcrum to transfer the article, then the fulcrum moves vertically to its next position. This segmentation of the originally simultaneous operations eliminates positional deviation and prevents sample holder tipping while maintaining operational efficiency
Solution Approach 2:
The patent completes the rotation operation fully before initiating the vertical movement of the fulcrum. This preliminary completion of one operation before starting the next ensures that the positional relationship is established correctly before any movement occurs, preventing tipping during the transition

AI summary
The purpose of the present invention is to provide a sample lifting/lowering mechanism and a sample conveying device able to transport a sample holder without tipping over the sample holder. In order to achieve said purpose, a sample lifting/lowering mechanism of the present invention comprises a sample holder carrying part for carrying the sample holder and able to rotate around a rotary shaft, and which lifts, lowers, and transports the sample holder loaded on the sample holder carrying part, wherein an operation in which the sample holder carrying part rotates around the rotary shaft is initiated after an operation in which the rotary shaft lifts or lowers is completed. Additionally, this sample conveying device comprises: a first conveying line that conveys the sample holder; a second conveying line that is provided above or below the first conveying line and conveys the sample holder; and the sample lifting/lowering mechanism that, when the sample holder conveyed by the first conveying line has been loaded, lifts or lowers the sample holder and transports the sample holder to the second conveying line.
