Pivoting Holder for Breakaway Pin Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for inserting stripping pins into stripping tools are not variable, large, or simplified, leading to inefficiencies and disruptions due to pin sticking in flexible feed lines.
Innovation Solution
A pivoting holder system with a pneumatic or electric drive allows for precise positioning and secure feeding of stripping pins, featuring a cylindrical block with a radial bore and adjustable sleeve-shaped shaft to accommodate pins of different lengths and shapes, ensuring accurate alignment and secure insertion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a flexible feed line is used to feed stripping pins, then the device can accommodate pin feeding, but pins often get stuck causing process disruptions
Solution Approach 1:
The feed line is segmented into a rigid channel portion and a flexible hose portion. The rigid channel provides stable, stick-free pin transport, while the flexible hose provides necessary adaptability. This segmentation resolves the contradiction by combining the advantages of both rigid and flexible structures.
Solution Approach 2:
A magazine serves as an intermediary component between the pin storage and the feed line. It receives pins from the flexible hose and feeds them into the rigid channel, acting as a buffer that decouples the flexible feeding mechanism from the rigid insertion mechanism, preventing pin sticking.
2Adaptability or versatility
If position-adjustable push rods are used to drive pins, then pin insertion is possible, but the device becomes large and less variable
Solution Approach 1:
The holder is made rotatable instead of fixed, allowing dynamic adjustment of the feed channel orientation. This rotational capability provides position adjustability without requiring multiple fixed push rods, reducing device size while maintaining versatility for different pin positions and types.
Solution Approach 2:
The rotatable holder with its radial bore and adjustable shaft can accommodate different pin types and positions by rotation and adjustment, making a single component perform multiple functions that would otherwise require multiple specialized components, thereby reducing overall device size.
3Productivity
If hand-driven nails are used as stripping tools, then makeready times are long for recurring jobs, but the tools are simple
Solution Approach 1:
The stripping pins are automatically fed and inserted into the stripping tool by the device, eliminating the need for manual nail insertion. The system serves itself by automatically replenishing and positioning pins, dramatically reducing makeready times for recurring jobs while keeping the stripping tool structure simple.

AI summary
The invention relates to a device for inserting a breakaway pin in a breakaway tool by means of a plunger (24), wherein the breakaway pin can be positioned at a desired position over the breakaway tool by means of a mounting element (12) and subjected there to pressure from the plunger (24). The mounting element (12) can thereby be pivoted into and out of the desired position.
