Solution Overview

Problem

Conventional sorting systems for vegetables and fruit, such as apples and pears, face issues with oversized products damaging equipment and causing processing delays, and diseased products contaminating the system, leading to inefficiencies and increased maintenance costs.

Innovation Solution

An eliminator system that uses a detector, such as a camera or sensors, to identify oversized and diseased products before sorting, coupled with a remover that can separate these products from the flow using a knock-out element and discharge conveyor, ensuring they are removed before they enter the sorting device, thereby preventing damage and contamination.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional sorting systems process products without pre-removal of oversized and diseased products, then the sorting process can continue without interruption, but equipment damage occurs and maintenance costs increase

Engineering Contradiction:
Improveequipment reliabilityVSAvoidsorting throughput
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system performs preliminary detection and removal of oversized and diseased products before they enter the sorting device. A detector identifies unsuitable products and a remover eliminates them from the flow, preventing equipment damage while maintaining continuous sorting operation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The invention extracts harmful elements (oversized and diseased products) from the product flow before they reach the sorting device. The remover mechanism selectively removes these problematic products, allowing the main sorting process to continue uninterrupted.

Inventive Principle:
Principle #2Taking out (Extraction)

2Adaptability or versatility

If the sorting device is designed to handle maximum product dimensions, then all products can be processed, but oversized products cause damage and processing delays

Engineering Contradiction:
Improveproduct size accommodationVSAvoidequipment damage from oversized products
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The detector and remover system performs preliminary identification and elimination of oversized products before they enter the sorting device. This allows the sorting device to be designed for optimal performance within safe dimensions while preventing oversized products from causing damage.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The eliminator system acts as an intermediary between the product flow and the sorting device. It detects and removes problematic products, protecting the sorting device from damage while maintaining the ability to handle the intended product range efficiently.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If diseased products are included in the sorting process, then no additional removal steps are needed, but contamination and infection spread occur

Engineering Contradiction:
Improvesorting efficiencyVSAvoidcontamination and infection spread
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The detector identifies diseased products before they enter the sorting device, and the remover eliminates them from the flow. This preliminary action prevents contamination and infection spread while maintaining efficient sorting operation on healthy products.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system extracts diseased products from the product flow before they can contaminate other products or the sorting device. The remover mechanism selectively removes infected items, preventing the spread of contamination.

Inventive Principle:
Principle #2Taking out (Extraction)

4Reliability

If a detector and remover system is added to the sorting line, then oversized and diseased products are removed effectively, but device complexity increases

Engineering Contradiction:
Improveproduct suitability assuranceVSAvoidsorting system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system replaces complex mechanical inspection methods with optical or sensor-based detection. The detector uses optical fields or other non-contact sensing to identify problematic products, avoiding the need for complex mechanical inspection equipment.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The detector and remover form an intermediary system that works in conjunction with the existing sorting device. This modular approach adds functionality without significantly complicating the overall system, as the eliminator operates independently but integrates seamlessly with the main sorting process.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The invention relates to an eliminator for detecting and removing products, such as vegetables and fruit, which are oversized and/or have undesired product properties, and to a singulator and sorting system provided therewith, and method therefor. The eliminator comprises: - a feed system for supplying products; - a detector configured to determine dimensions and/or product properties of a product of the supplied products; - a controller operatively connected to the detector and configured to determine on the basis of determined dimensions and/or product properties of the product whether the product is suitable for processing in a sorting device; and - a remover operatively connected to the controller for separating products which are not suitable for processing in the sorting device from products which are suitable for processing in the sorting device.
