Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing testing and sorting machines using permanently mounted glass rings suffer from mechanical wear, leading to measurement inaccuracies and increased false positive rates due to scratches and defects, with manual replacement being subjective, time-consuming, and inefficient.
Innovation Solution
A semi-automated changing unit for glass rings in the testing and sorting machine, featuring a frame-like base with lifting cylinders and locking elements, allows for the automated or manual exchange of glass rings without manual intervention, ensuring precise alignment and efficient handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If glass rings are permanently mounted in the testing and sorting machine, then the machine structure is simplified and operation is easier, but the glass rings suffer from mechanical wear leading to measurement inaccuracies and increased false positive rates
Solution Approach 1:
The glass ring is changed from a permanently fixed component to a dynamically replaceable one. The mounting system allows the glass ring to be easily removed and replaced when wear occurs, transforming the static permanent mounting into a dynamic interchangeable configuration that maintains measurement precision while simplifying operation.
Solution Approach 2:
The glass ring is treated as a consumable component that is discarded when worn and replaced with a new one. The system recovers the worn glass ring for replacement, allowing continuous operation with fresh glass rings that maintain measurement accuracy, while the replacement process is simplified through the designed mounting mechanism.
2Adaptability or versatility
If glass rings are replaced manually by operators, then flexibility is maintained, but the process is time-consuming and subject to human error affecting reproducibility
Solution Approach 1:
A spare glass ring is pre-positioned in the mounting system during normal operation. When the current glass ring needs replacement, the operator simply swaps to the pre-positioned spare, eliminating the need for complex removal and installation procedures. This preliminary positioning of backup components dramatically reduces replacement time while maintaining operational flexibility.
3Productivity
If multiple testing stations are arranged around the glass ring in a confined space, then productivity is increased, but manual replacement of glass rings becomes more difficult and time-consuming
Solution Approach 1:
The glass ring mounting system is segmented into modular components with standardized interfaces. This segmentation allows the glass ring to be independently removed and replaced without affecting the compact arrangement of multiple testing stations. The modular design enables easy maintenance while preserving the high-density configuration that ensures productivity.

AI summary
The invention relates to a testing and sorting machine for inspecting and/or sorting large quantities of precision parts, wherein the testing and sorting machine comprises at least one glass ring for receiving and transporting the individual precision parts and at least one testing station for evaluating the precision parts. The object of the invention is to provide a glass ring exchange unit for such a testing and sorting machine, which enables a semi-automated exchange of the glass rings without manual intervention by an operator in fixing the position of the glass rings, thus achieving simpler, safer, and more efficient handling when changing glass rings compared to known technical solutions.The problem is solved by the testing and sorting machine (1) having a changeover device (8) designed to remove the glass ring (2) from the testing and sorting machine (1) and to insert it into the testing and sorting machine (1), wherein the changeover device (8) has a frame-like base body with a contour in which a changeover frame (10) is supported in a translationally displaceable manner, wherein several lifting cylinders (9) for raising and lowering the glass ring (2) are arranged on the changeover frame (10), wherein the changeover device (8) has two locking elements (11; 12) for position fixing, and wherein a specific procedure sequence for operating a testing and sorting machine (1) designed in this way is proposed.
