Solution Overview

Problem

The manual and time-consuming process of removing packaging from bales, which is necessary for efficient material handling and processing, is costly in terms of resources and tools, especially when dealing with large quantities.

Innovation Solution

A bale fork with a clamping member and opening member that can automatically remove packaging by clamping, cutting, and separating it from the bale, allowing for complete automation of the process, even with irregularly shaped bales.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If manual bale opening operation is performed by operator using cutting instrument, then packaging can be removed, but the process is time-consuming and requires human resources and tools

Engineering Contradiction:
Improveautomation of packaging removalVSAvoidtime for bale opening operation
Core Design Contradiction:
Extent of automationVSLoss of time

Solution Approach 1:

The bale opening system performs the packaging removal operation automatically without requiring manual intervention. The cutting member is actuated by the bale itself as it passes through the fork, with the packaging being cut and removed by the mechanical action of the moving bale against the fixed cutting element, thereby automating the previously manual task and reducing both time and human resource requirements

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The cutting member is positioned and prepared in advance within the fork structure, ready to engage the packaging as the bale is inserted. The system pre-positions the cutting element at the optimal location and orientation before the bale opening operation begins, enabling immediate and efficient packaging removal once the bale is in place

Inventive Principle:
Principle #10Preliminary action

2Reliability

If packaging is not removed completely, then health of farm animals can be compromised or recycling process efficiency reduced, but complete removal increases processing time and cost

Engineering Contradiction:
Improvecomplete packaging removalVSAvoidbale processing throughput
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The packaging removal process is segmented into distinct functional zones within the fork: an initial cutting zone where the cutting member severs the packaging, and a subsequent removal zone where the packaged material is separated from the bale. This segmentation ensures that packaging is both cut and completely removed, preventing any residue from contaminating the material while maintaining efficient processing through specialized zones for each function

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The fork structure acts as an intermediary mechanism between the bale and the packaging removal function. The clamping members and cutting member work together as intermediary elements that grasp, position, and cut the packaging, ensuring complete removal without requiring excessive processing time or compromising productivity

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of manufacture

If fork structure is simplified, then manufacturing cost is reduced, but ability to handle irregularly shaped bales may be compromised

Engineering Contradiction:
Improvefork structure simplicityVSAvoidhandling of irregularly shaped bales
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The clamping members are designed to be movable rather than fixed, allowing them to adapt their position and configuration to accommodate bales of various shapes and sizes. The clamping members can move independently to grasp irregular surfaces and maintain secure holding, providing versatility without requiring a complex overall fork structure

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The fork structure incorporates multi-functional elements that can perform multiple operations. The same clamping members used for holding the bale are also involved in positioning it for cutting, and the cutting member serves both to sever packaging and facilitate its removal. This multi-functionality reduces the need for additional specialized components, simplifying manufacturing while maintaining adaptability

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

AI summary

Bale fork comprising frame with connection interface for engaging with movement element of actuator machine, the following being mounted on the frame: coupling member for mechanically coupling to a bale, clamping member for hooking and clamping a first packaging portion of the bale when coupled to the coupling member, and opening member for acting upon a second packaging portion with one first packaging portion in a clamped condition by the clamping member so as to release the packaging from the bale. The clamping member comprises teeth to penetrate the bale coupled to the coupling member and a comb element provided with prongs, wherein comb and teeth are slidably mounted in the clamping member with respect to one another, so as to switch between a clamping condition in which at least one prong of the comb occludes a space between a pair of adjacent teeth, thereby clamping the first portion of the packaging between a tooth of the pair of adjacent teeth and the at least one prong of the comb, and a releasing condition in which the at least one prong releases said first packaging portion.
