Divider Fin Assembly for Die-Cut Blank Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional die-cutting machines require manual removal of gutter strips, leading to repetitive motion injuries and slowed production due to the need for hand removal of waste material between cut blanks.
Innovation Solution
A fin assembly is attached to the die-cutting machine, featuring thin, adjustable fins and backstops that guide and align cut blanks, eliminating the need for gutter strips by maintaining proper alignment and separation as the blanks are fed through the machine.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If gutter strips are left between adjacent blanks to hold them together and prevent ink bleeding, then the blanks can be stacked and handled properly, but the gutter strips must be manually removed after cutting which leads to repetitive motion injuries and significant slowing of the die cutter run speed
Solution Approach 1:
The invention extracts and eliminates the gutter strip from the process by using a fin assembly that allows blanks to be cut without connecting material, thereby removing the need for manual gutter removal while maintaining blank separation and alignment
Solution Approach 2:
The fin assembly acts as an intermediary device between the cutting process and blank handling, providing the necessary separation and alignment functions previously performed by gutter strips, but without requiring manual intervention for removal
2Manufacturing precision
If gutter strips are used to separate and align blanks, then proper alignment is maintained, but hand removal of gutter strips is required which causes repetitive motion injuries
Solution Approach 1:
The fin assembly enables the system to serve itself by automatically maintaining blank separation and alignment through the fin structure, eliminating the need for human intervention in gutter removal and thus preventing repetitive motion injuries
3Ease of manufacture
If manual removal of gutter strips is performed, then blanks can be processed further, but the die cutter run speed is significantly slowed
Solution Approach 1:
The fin assembly performs the separation and alignment function preliminarily during the cutting process itself, so that when blanks exit the cutter they are already properly separated and ready for handling, eliminating the need for subsequent manual gutter removal and maintaining high run speed

AI summary
A fin assembly for attachment to a die cutting machine to guide and align at least two blanks cut from a sheet in the machine as the blanks are fed through the machine. The fin assembly includes at least one thin plate-like fin having length and height dimensions and a narrow thickness. The fin is mounted in the machine so that the length dimension is in substantial alignment with a respective cut separating two blanks cut in the machine, so that the blanks fall on opposite sides of the fin as they are fed through the machine, whereby the fin keeps the blanks separate and aligns them as they are fed through the machine. At least one back stop is associated with the fin to prevent blanks from moving in a reverse direction and falling out of the machine when they fall past the fin.
