Fish Fillet Skinning Device with Automatic Cutting Gap Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fish fillet skinning devices require manual adjustment of cutting gap sizes and roller teeth based on fish size, leading to increased operational effort, downtime, and suboptimal cutting results for varying fillet sizes, necessitating pre-sorting.
Innovation Solution
A device with a pivoting main cutting edge and a secondary cutting edge, controlled by an evaluation and control unit, automatically adjusts the cutting gap and cutting edge positions based on detected fish fillet size, allowing for independent and precise adaptation during processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual adjustment of cutting gap size and roller teeth is performed based on fish size, then cutting results can be optimized for specific fillet sizes, but operational effort increases and downtime occurs during adjustments
Solution Approach 1:
The cutting gap size is made dynamically adjustable through an electrically adjustable mechanism that allows the cutting edge to be positioned at different distances from the drive roller based on detected fillet size, eliminating manual adjustment and enabling continuous operation
Solution Approach 2:
The system changes the cutting gap parameter automatically based on detected fillet size, allowing optimal cutting parameters to be applied for different fillet dimensions without manual intervention or production stoppage
2Productivity
If different drive rollers with different tooth counts are used for different fish sizes, then skinning performance is optimized, but device complexity increases and changeover time increases
Solution Approach 1:
A single drive roller with adjustable cutting gap serves multiple functions for different fillet sizes, replacing the need for multiple specialized rollers with different tooth counts, thereby simplifying the device while maintaining optimized performance across size ranges
Solution Approach 2:
The system uses dynamic adjustment of the cutting gap rather than static changes in roller configuration, allowing one roller to adapt to different fillet sizes through electrical adjustment mechanisms
3Device complexity
If fixed cutting gap size is used, then device complexity is reduced, but cutting quality deteriorates for varying fillet sizes
Solution Approach 1:
The cutting gap parameter is made variable and is automatically adjusted based on detected fillet size, allowing optimal cutting quality for different dimensions while maintaining relatively simple device architecture through automated control
4Manufacturing precision
If pre-sorting of fillets is performed, then cutting quality is maintained for different sizes, but productivity decreases due to additional processing time
Solution Approach 1:
The system performs preliminary detection of fillet size before cutting and automatically adjusts cutting parameters in advance, eliminating the need for manual pre-sorting while maintaining optimal cutting quality for each fillet size
Solution Approach 2:
The system uses detection means to measure fillet size and feeds this information back to automatically adjust the cutting gap, creating a closed-loop control system that maintains cutting quality without manual intervention or pre-sorting

AI summary
The invention relates to a device (10) for removing a surface layer including the skin from fish fillets (11), comprising: a feeding apparatus (12) in the region of a removal assembly (13); an entraining roller (15), which is rotationally driven; and a main blade (16) arranged in the region of the entraining roller for removing the surface layer, wherein the main blade is arranged at a distance from the entraining roller in order to form a cutting gap (S) and is designed to be deflectable relative to the entraining roller. The device has a measuring assembly (18) comprising at least one detection element (19) which is designed and set up to determine size-relevant data of the fish fillets, and an evaluating and control unit (20), the evaluating and control unit being connected by means of signal lines (21) to the detection element and to the main blade, in order to automatically control the size of the cutting gap between the main blade and the entraining roller depending on the previously determined fish fillet size.
