Rivet Holder Structure for Secure Release Into Guide Block Bores
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing collating systems for rivets lack efficient mechanisms to securely hold and easily release rivets in a pattern matching guide block bores, leading to difficulties in loading and driving rivets into conveyor belt fasteners.
Innovation Solution
A collating system comprising rivet holders with top and bottom plate members secured together, featuring drive heads and frangible portions, retaining webs with inclined surfaces and grooves for flexibility, and radially enlarged openings to facilitate easy insertion and release of rivets, ensuring secure holding and efficient driving into guide block bores.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If rivets are held in a conventional holder without frangible portions, then the rivet holding structure is simple, but the rivet cannot be quickly released for driving into guide block bores
Solution Approach 1:
The holder is divided into a body portion and a frangible portion that can break away. The frangible portion includes a break line that allows clean separation when force is applied, enabling quick rivet release while maintaining structural integrity during transport and storage.
Solution Approach 2:
The frangible portion is pre-positioned and pre-configured in the holder structure before use. The break line is pre-formed so that when the rivet needs to be driven, the frangible portion can immediately break away without requiring complex release mechanisms or additional steps.
2Reliability
If rivets are secured tightly in the holder during transit, then accidental removal is prevented, but quick release for driving becomes difficult
Solution Approach 1:
The holder transitions from a static secured state during transport to a dynamic release state when force is applied. The frangible portion remains intact and securely holds the rivet during storage, but can dynamically break away when the user applies force to the rivet head or uses a driving tool, providing both security and ease of release.
3Adaptability or versatility
If the holder uses a rigid structure without flexibility features, then manufacturing is simpler, but the holder cannot adapt to alignment variations with guide block bores
Solution Approach 1:
The holder has different structural properties in different locations: the body portion is rigid to maintain overall structure and rivet positioning, while the frangible portion includes flexibility features that allow local adaptation to alignment variations. This localized flexibility enables the holder to accommodate minor misalignments with guide block bores without compromising overall structural integrity.

AI summary
A collating system for rivets is provided that includes a rivet holder for supporting rivets in a predetermined pattern. In one form, the rivet holder includes a body having cavities for supporting the rivets therein. The rivet holder body includes a top plate member and a bottom plate member. The rivet holder has drive heads connected to the top plate member via frangible portions and the bottom plate member has retaining webs disposed below the drive heads. The top and bottom plates are secured together to capture heads of the rivets between the drive heads and retaining webs. The drive heads may be driven downward to drive the rivet heads from the rivet holder and into bores of a guide block with the retaining webs flexing to release the rivet head from the lower bottom plate member. A method of using the rivet collating system is also disclosed.
