Coin-Shaped Fastener Feeding Path for Inversion-Free Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for fastening coin-shaped metal parts, such as metal for piercing, are inefficient due to manual placement and varying fastening positions, leading to prolonged setup times.
Innovation Solution
A device and method featuring a hollow pillar-shaped portion with a holding mechanism, a part passage route, a guide portion, and a fastening portion that ensures the metal parts are loaded and fastened correctly by maintaining parallel surfaces, preventing inversion and enabling automatic feeding and fastening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual placement method is used, then parts can be positioned at fastening position, but fastening position varies and setup time increases
Solution Approach 1:
The device enables automatic feeding and positioning of coin-shaped parts through self-aligning mechanisms. The part passage route portion with specific cross-sectional width and the guide portion work together to automatically orient and position parts without manual intervention, achieving consistent fastening positions and reducing setup time
Solution Approach 2:
The holding portion acts as an intermediary mechanism that temporarily holds parts in a controlled manner before they are fed to the fastening position. This intermediary structure ensures parts are properly positioned and oriented during the transition from storage to fastening, eliminating position variation
2Productivity
If conventional feeder device is used, then parts can be discharged, but parts may be inverted and positioning is time-consuming
Solution Approach 1:
The part passage route portion is designed with an asymmetric cross-sectional width that does not cause inversion of the front and back of the part. This asymmetric geometry ensures parts maintain their correct orientation (front surface and back surface parallel in vertical direction) as they pass through, preventing inversion and enabling rapid automated processing
Solution Approach 2:
The guide portion performs preliminary action by guiding parts from a vertical orientation state to a horizontal orientation state before fastening. This pre-positioning ensures parts are correctly oriented at the fastening portion, eliminating the need for time-consuming manual positioning and enabling high-speed automated operation

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution significantly reduces setup time by ensuring accurate and rapid loading and fastening of metal parts, enhancing the efficiency of the fastening process.
Implementation Method 1
a part passage route portion having a cross section of a width that does not cause inversion of the front and back of the part, extending downward from the holding portion so that the part can pass through while maintaining a state in which the front surface and the back surface of the part are parallel to each other in the vertical direction

AI summary
A feeding and fastening device for a coin-shaped fastener and comprising: a punch tool; a feeding device configured to feed the fastener one at a time; a hollow pillar-shaped portion below the punch tool; a holding portion to temporarily hold the fastener fed though a side surface thereof and to release the fastener when the punch tool pushes down on that fastener; a part passage route portion below the holding portion for guiding the fastener downward in a vertical orientation by means of a cross section with a width that prevents inversion; a guide portion below the passage route portion guides the fastener from the vertical orientation to a horizontal orientation; and a fastening portion below the guide portion receives the fastener in the vertical orientation and locates the fastener above the workpiece until struck by the punch tool.
