Clip Machine Displacement Shear Reinforcement for Packaging Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sausage clipping machines face issues where the shortened displacement shears can penetrate or damage packaging casings, especially with large-caliber sausage-shaped products, leading to unreliable closure and potential damage during the constricting process.
Innovation Solution
A displacement assembly with a reinforcement that replicates the cut-off section of the shortened displacement scissors, positioned on the first pair of scissors, closes the gap created by shortening, preventing the packaging cover from being caught and ensuring safe movement of the scissors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lower displacement scissor is shortened to release the suspension element, then the suspension element can be released, but the packaging casing may be penetrated or damaged during the constricting process
Solution Approach 1:
A reinforcement element is introduced as an intermediary component on the upper displacement scissor to compensate for the gap created by shortening the lower scissor. This reinforcement acts as a mediator that prevents direct contact between the shortened lower scissor and the packaging casing, thereby preventing penetration or damage while maintaining the suspension element release function
Solution Approach 2:
The reinforcement element is positioned in advance on the upper displacement scissor to provide protective cushioning before the constricting process begins. This pre-positioned reinforcement prevents harmful contact between the shortened lower scissor and the packaging casing during the constricting operation, ensuring integrity is maintained throughout the process
2Ease of operation
If the lower displacement scissor is shortened to enable loop feeding, then loops can be fed and fastened to the sausage, but the gap created may cause collision or damage during movement
Solution Approach 1:
The reinforcement element serves as an intermediary that fills the gap created by shortening the lower displacement scissor. This prevents harmful collisions between the shortened scissor and other components during movement, while still allowing the loop feeding function to operate effectively
Solution Approach 2:
The reinforcement element is positioned in advance to provide preliminary protective action against potential collisions or damage that could occur during the movement of the shortened displacement scissor. This pre-positioned protection prevents harmful interactions before they can occur

AI summary
The displacement assembly has two pairs of displacement shears (10,20,30,40) which are arranged in parallel manner. The displacement shears reversibly move on one another for cutting the stuffed packaging wrapper for forming a braid free of stuffing. The former displacement shear of the former pair of displacer shears has a reinforcement (50), which replicates the contour of the sections of the former displacement shear of the latter pair of displacer shears.
