Clipper Blow-Off Pulse Valve for Jammed Clip Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional clipper systems face inefficiencies in operating the clip-blow off mechanism, which is crucial for maintaining cleanliness and removing unwanted material from clip dies, leading to potential jams and reduced reliability.
Innovation Solution
The implementation of a pressurized gas pulse system, utilizing a pulse valve connected to a punch or gate valve, which generates a clip blow-off pulse of pressurized gas across the clip dies during the reset or idle period of the clipping cycle, ensuring efficient and reliable operation, especially in rotating multi-clipper platform systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional clip-blow off mechanisms are used, then clip dies can be kept clean and unwanted material can be ejected, but the system operates inefficiently and unreliably with potential jams
Solution Approach 1:
The system uses periodic pulsing of pressurized gas through pulse valves during reset or idle periods of the clipping cycle, rather than continuous operation. This periodic action maintains die cleanliness while minimizing interference with the clipping productivity, resolving the contradiction between reliability and efficiency
Solution Approach 2:
The clip-blow off operation is performed during the reset or idle period before the next clipping cycle begins. This preliminary action ensures the die is clean and ready for the next clip application, preventing jams and improving reliability without impacting the actual clipping productivity
2Reliability
If clip-blow off operation is implemented, then die cleanliness is maintained, but system complexity increases with additional valves and conduits
Solution Approach 1:
The pressurized gas system serves multiple functions: it powers the punch valve, gate valve, and pulse valve for clip-blow off operation. By using a single pressurized gas source for multiple functions, the system maintains die cleanliness while minimizing the addition of separate systems, thus reducing overall complexity
Solution Approach 2:
The clip-blow off system is integrated with the existing pressurized gas infrastructure of the clipping machine. The pulse valves are connected to the same pressurized gas source that operates other clipping components, merging functions and reducing the number of separate systems needed
