Part Orientation Routing for Stopper-Free Branch Merging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing part orienting systems require stopper pins to manage the merging of parts, which increases maintenance time and effort.
Innovation Solution
A part orienting system that determines whether parts are facing up or down using a determining and sorting unit, allowing them to be fed into separate branch passages without stopper pins, ensuring smooth merging by orienting the front surfaces in the same direction at the merge point.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If stopper pins are used at branch passages to manage part merging, then part collision at merge points is reduced, but system complexity and maintenance effort increase
Solution Approach 1:
The invention extracts and eliminates the stopper pins from the system by implementing a determining and sorting unit that directs parts to different branch passages based on their orientation. This removes the need for mechanical stoppers while maintaining collision reduction through intelligent routing.
Solution Approach 2:
The patent replaces the mechanical stopper pin system with a determination and sorting mechanism that uses detection and control logic to manage part flow. This substitutes physical mechanical intervention with a systematic routing approach based on part characteristics.
2Ease of operation
If stopper pins are installed at branch passages, then part flow control is improved, but maintenance time and effort increase
Solution Approach 1:
By removing stopper pins from the system, the invention eliminates the maintenance burden associated with these components while maintaining effective part flow control through the determining and sorting unit.
Solution Approach 2:
The determining and sorting unit enables the system to automatically manage part routing based on detected part characteristics, eliminating the need for manual intervention or maintenance of mechanical stopper mechanisms.
3Productivity
If parts are fed into separate branch passages without orientation control, then feeding efficiency is improved, but collision at merge points increases
Solution Approach 1:
The determining and sorting unit performs preliminary orientation detection and routing decisions before parts enter the branch passages. This advance sorting ensures that parts are directed to appropriate branches based on their orientation, preventing collisions at the merge point while maintaining efficient parallel feeding.
Solution Approach 2:
The system uses the determining unit to detect part orientation and provides feedback control by routing parts to different branch passages accordingly. This closed-loop approach ensures that parts with similar orientations are grouped together, reducing collision risk at the merge point.

AI summary
Parts merge smoothly without any stopper at a branching region. A determining and sorting unit determines, between an introduction passage and a branching region, whether weld nuts at rest are facing up or down. The weld nuts determined as facing up are fed to a first branch passage, whereas the weld nuts determined as facing down are fed to a second branch passage.
