Dynamic Pig Part Deskinner for Continuous Conveyor Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pig part processing plants face challenges in efficiently deskining suspended pig parts, particularly when the retaining assembly carrying the pig part moves continuously, making it difficult to maintain effective skin removal without compromising processing efficiency.
Innovation Solution
The implementation of a deskinner unit with a knife and a skin gripper, mounted on a carrier structure with actuators that move the deskinner between upper and lower positions, allowing for efficient skin removal without the need for the deskinner to move with the pig part in the machine direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the retaining assembly moves continuously to maintain processing efficiency, then productivity is improved, but it becomes difficult to maintain effective skin removal
Solution Approach 1:
The deskinner is mounted on a carrier structure with actuators that enable it to move between upper and lower positions dynamically. This dynamic positioning allows the deskinner to engage the skin effectively during the continuous movement of the retaining assembly, resolving the contradiction between maintaining processing efficiency and ensuring reliable skin removal.
2Device complexity
If the deskinner remains stationary while the pig part moves continuously, then device complexity is reduced, but skin removal effectiveness deteriorates
Solution Approach 1:
Instead of making the entire deskinner system move with the pig part, the invention uses a stationary carrier structure with actuators that provide controlled movement between upper and lower positions. This dynamic adjustment maintains skin removal effectiveness while keeping the overall device structure relatively simple and stationary.
3Reliability
If the deskinner moves with the pig part in the machine direction, then skin removal effectiveness is improved, but device complexity and energy consumption increase
Solution Approach 1:
The invention avoids the complexity of making the deskinner move continuously with the pig part by using a stationary carrier structure. Instead, actuators provide controlled movement between upper and lower positions only when needed for skin engagement and removal, significantly reducing device complexity and energy consumption while maintaining effectiveness.
Solution Approach 2:
The deskinner performs periodic movement between upper and lower positions using actuators, rather than continuous movement. This periodic action occurs only during the skin removal phase, reducing overall energy consumption and mechanical complexity while maintaining skin removal effectiveness.
