Sample Rack Conveying Unit Single Driving Portion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sample rack conveying units require multiple driving portions, increasing costs and complicating the mechanism, as seen in Japanese Patent Laid-Open No. 6-1427, which necessitates a reduction in the number of components to simplify the conveying process.
Innovation Solution
A sample rack conveying unit incorporating a sliding rail plate with a groove for the sample rack, an endless driving belt, pulleys, and a presser mounted on the belt, along with guide plates to manage direction changes, utilizing a single driving portion to convey the sample rack efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple driving portions are used to convey the sample rack in different directions, then the conveying capability is improved, but the device complexity and cost increase
Solution Approach 1:
The patent combines multiple driving functions into a single driving portion that sequentially conveys the sample rack in different directions. The first rack conveying conveyor and second rack conveying conveyor are integrated into one unified driving system, eliminating the need for separate driving portions and reducing overall device complexity while maintaining the capability to convey the sample rack in multiple directions.
Solution Approach 2:
The single driving portion is designed to perform multiple functions by sequentially conveying the sample rack along different paths. It first conveys the sample rack in a first direction to a first position, then conveys it in a second direction to a second position, effectively replacing what would traditionally require multiple specialized driving portions.
2Manufacturing precision
If multiple driving portions are used to rotate and convey the sample rack, then the conveying precision is improved, but the mechanism complexity increases
Solution Approach 1:
The patent integrates the rotational conveying function and linear conveying function into a single driving portion. The sample rack is rotated to a predetermined angle and then conveyed linearly, all controlled by one driving mechanism rather than separate mechanisms for rotation and translation, thereby simplifying the overall mechanism while maintaining conveying precision.
3Adaptability or versatility
If three driving portions are used to convey the sample rack through disc and conveyors, then the conveying flexibility is improved, but the cost and mechanism complexity increase
Solution Approach 1:
The patent merges the functions of the first rack conveying conveyor, second rack conveying conveyor, and disc rotation into a single integrated driving portion. This unified approach reduces the total number of driving components required, lowering manufacturing costs and simplifying the mechanism while preserving the flexibility to convey samples through different paths and positions.
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 configuration reduces the number of driving portions, simplifies the mechanism, and stabilizes the conveyance of the sample rack, preventing operational failures and ensuring consistent positioning, thereby reducing costs and enhancing operational reliability.
Implementation Method 1
The presser passes through the groove portion and presses the sample rack. The presser is mounted on the driving belt. The driving belt is stretched across the plurality of pulleys.

AI summary
A sample rack conveying unit 30 includes a sliding rail plate 53, a presser 66, a first guide plate 55, and a second guide plate 56. The sliding rail plate 53 has a groove portion 71 formed along a track on which a sample rack 90 slides and along which the sample rack 90 is conveyed. The presser 66 passes through the groove portion 71 and presses the sample rack 90. The first guide plate 55 is arranged on an outer side of a curved portion in a radial direction. The second guide plate 56 is arranged on an inner side of the curved portion in the radial direction.
