Solution Overview

Problem

Existing machines for breaking down and distributing bales of animal bedding or fodder are complex and inefficient, particularly when dealing with cylindrical bales, as they often require manual removal of ties and protective coverings, which can be difficult or impossible without extraction rollers.

Innovation Solution

A machine with a cutting device integrated into the bottom wall that can cut ties, nets, or protective coverings in the lower part of the bale, featuring movable knives with linear movement, allowing for easier removal by reducing the effort required to extract these packaging materials manually.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a roller extraction system is used to remove ties from cylindrical bales, then the ties can be removed effectively, but the device complexity increases significantly

Engineering Contradiction:
Improveease of tie removalVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The invention extracts the cutting function from a complex roller extraction system and implements it through a simple knife that cuts the ties in the lower part of the bale, allowing manual removal without requiring a roller mechanism

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of using a roller to extract ties from the upper or lateral parts of the bale, the invention inverts the approach by cutting ties from the lower part of the bale where a simple knife can access them, enabling manual removal without complex mechanisms

Inventive Principle:
Principle #13The other way round (Inversion)

2Adaptability or versatility

If a roller extraction system is used, then cylindrical bales can be processed, but parallelepiped bales cannot be handled

Engineering Contradiction:
Improvebale shape adaptabilityVSAvoidprocessing reliability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The knife-based cutting device mounted on the bottom wall can process both cylindrical and parallelepiped bales, providing universal functionality across different bale shapes without requiring shape-specific mechanisms

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The cutting device can be configured with one or multiple knives positioned at different locations on the bottom wall, allowing adaptation to different bale shapes and sizes while maintaining a simple overall structure

Inventive Principle:
Principle #1Segmentation

3Device complexity

If manual cutting and pulling of ties is used, then the device complexity is reduced, but the effort required to remove ties increases significantly

Engineering Contradiction:
Improvedevice complexityVSAvoidforce required for tie removal
Core Design Contradiction:
Device complexityVSForce

Solution Approach 1:

The knife performs a preliminary cutting action on the ties in the lower part of the bale before manual removal, weakening the ties so that they can be pulled off with minimal effort without requiring complex extraction mechanisms

Inventive Principle:
Principle #10Preliminary action

AI summary

The present invention relates to a machine (100) for undoing and dispensing bales of animal litter or bales of fodder, comprising: - a bottom wall (Pf; Pf') intended to receive the bale (B), - a member (180) for ejecting the material which constitutes the bale or a member (320) for unwinding the bale, - a device (300) for cutting the link of the net or of the protective casing which surrounds the bale. According to the invention, the cutting device (300) is disposed in the bottom wall (Pf; Pf') or in the extension thereof or in the vicinity thereof and disposed so that it can act in the lower part of the bale, the cutting device (300) including a cutting member (T). When the bale is loaded onto the bottom wall, the cutting device can then cut the link, net or protective cover which surrounds the bale.
