Clipping Tool Pusher Ejection Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In packaging machines, closure clips often adhere to the closing tools, causing damage to packaging casings and increasing waste and maintenance costs, especially when high pressure is required for closure.
Innovation Solution
A clipping tool assembly with a pusher means that pushes the closed closure clip out of the second closing tool, preventing it from adhering and ensuring secure removal without damaging the casing material, using a pusher element and drive mechanism, such as a piston/cylinder drive or pressurized air, to facilitate the clip's ejection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If high pressure is applied by closing tools to secure closure clips, then closing force is improved, but closure clips adhere to the tools causing damage to packaging casings and increasing waste
Solution Approach 1:
The patent introduces a pusher means that extracts the closure clip from the second closing tool after closing is complete. The pusher element pushes the closure clip out of the second closing tool, preventing adhesion and damage to packaging casings, thus resolving the contradiction between achieving high closing force and preventing waste.
2Force
If high pressure is applied by closing tools to secure closure clips, then closing force is improved, but maintenance costs increase due to clips remaining in tools
Solution Approach 1:
The pusher means systematically removes closure clips from the second closing tool after each closing operation. This prevents clips from remaining in the tool, eliminating the need for frequent maintenance and repairs, thus reducing maintenance costs while maintaining high closing force capability.
3Reliability
If closure clips are securely closed by closing tools, then closing reliability is improved, but closure clips adhere to tools requiring process stoppage for removal
Solution Approach 1:
The pusher means automatically extracts closure clips from the second closing tool immediately after closing is complete. This ensures closure reliability is maintained while preventing clips from adhering to the tool, thereby eliminating process stoppages and maintaining continuous production.
Solution Approach 2:
The pusher element is positioned and activated in advance to push the closure clip out of the second closing tool before the next closing operation begins. This preliminary action ensures no clips remain in the tool, preventing production interruptions and maintaining continuous operation.
Applied Scientific Principles
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 pusher means effectively prevents closure clips from being left in the tools, reducing waste and maintenance costs by ensuring secure removal and preventing damage to packaging casings, enhancing the closing process for tubular and bag-shaped products.
Implementation Method 1
a pusher means for pushing the closure means just closed out of the second closing tool
Implementation Method 2
using a pusher element and drive mechanism, such as a piston/cylinder drive or pressurized air, to facilitate the clip's ejection

AI summary
The present invention relates to a clipping tool assembly for closing at least one closure means, like a closure clip, in a packaging machine, like a clipping machine, for closing tubular or bag-shaped packaging casings. The clipping tool assembly comprises a first closing tool and a second closing tool, wherein at least the first closing tool is reversibly movable towards the second closing tool, between an opened position and a closed position, for closing the at least one closure means, and a drive means for reversibly moving at least the first closing tool towards the second closing tool in a closing direction. The clipping tool further comprises a pusher means provided in the region of the second closing tool for pushing the closure means just closed out of the second closing tool.
