Multi-lane Slicing Device Defect Distribution for Continuous Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-lane slicing devices face challenges in maintaining a continuous portion flow due to loading pauses and differences in product lengths and weights, leading to inefficiencies and increased system complexity, requiring buffer sections and transverse distributors.
Innovation Solution
The method involves calculating expected positions of defects in the portion stream and adjusting the slicing process to distribute actual imperfections throughout the sequence, using data from sensors and scanners to control the cutting knife and product feed, allowing for targeted creation of blank cuts and redistribution of defects to maintain a continuous flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If products are fed uniformly to all lanes with a common controller, then the system structure is simplified, but the portion flow continuity deteriorates due to loading pauses and product length variations
Solution Approach 1:
The patent divides the product feeding control into lane-specific segments, with each lane having its own controller that independently manages product feeding, slicing, and defect distribution. This segmentation allows each lane to operate autonomously, maintaining continuous portion flow even when other lanes experience loading pauses or product variations.
Solution Approach 2:
The system dynamically adjusts the slicing process based on real-time product data. Controllers monitor product length, weight, and defect positions, then adaptively modify slicing parameters and defect distribution strategies to maintain continuous portion flow. This dynamic control enables the system to respond to varying product characteristics without interrupting the portion stream.
2Reliability
If buffer sections are added after slicing to handle loading pauses, then portion flow continuity is improved, but the system length and space requirements increase
Solution Approach 1:
The system performs preliminary actions by proactively distributing defects and adjusting slicing parameters before loading pauses occur. Controllers predict potential interruptions and redistribute defects to maintain continuous portion flow, eliminating the need for buffer sections that would otherwise be required to absorb flow interruptions.
Solution Approach 2:
The patent ensures continuous useful action by maintaining an uninterrupted portion stream through intelligent defect distribution and adaptive slicing control. The system keeps the slicing process continuously productive by redistributing defects to prevent gaps in the portion flow, eliminating the need for stationary buffer sections and reducing overall system length.
3Adaptability or versatility
If Vario feeders with individual lane control are used, then product feed flexibility is improved, but the portion flow continuity deteriorates due to non-uniform product lengths creating gaps
Solution Approach 1:
The system implements feedback control where controllers continuously monitor product characteristics (length, weight, defect positions) and adjust slicing parameters in real-time. This feedback mechanism allows the system to maintain continuous portion flow despite variations in product length by dynamically compensating for differences between lanes through adaptive defect distribution and slicing control.
Solution Approach 2:
The patent utilizes parameter changes by dynamically modifying slicing parameters (cut positions, knife speed, feed rate) based on detected product characteristics. Controllers adjust these parameters in response to product length variations and defect positions, enabling the system to maintain continuous portion flow while accommodating the flexibility needed for different product specifications.
4Manufacturing precision
If the slicing process is strictly controlled to produce uniform portions, then manufacturing precision is improved, but the system cannot handle product variations without buffer sections
Solution Approach 1:
The system employs self-service control where lane-specific controllers autonomously manage their own slicing processes based on detected product characteristics. Each controller independently adjusts slicing parameters and defect distribution to maintain both portion uniformity and continuous flow, eliminating the need for complex centralized buffer systems while preserving manufacturing precision.

AI summary
The invention relates to a method for generating a multi-lane portion stream in which several food products are simultaneously fed to a cutting unit and cut into portions, wherein product- and/or lane-specific data are determined before and/or during cutting, expected positions of defects in the portion stream are calculated on the basis of the data, and the cutting process is adapted such that at least some actual positions of defects differ from the expected positions.
