Solution Overview

Problem

Conventional agricultural balers face challenges with heavy wrapping material rolls that are difficult to maneuver, limit storage capacity, and require power to feed wrapping material, leading to inefficiencies in bale wrapping processes.

Innovation Solution

A wrapping system using flat, folded stacks of wrapping material, where a feed plate system with a serrated edge and independently movable cutting knife applies varying tension to cut the material, allowing for efficient dispensing and cutting of wrapping material without the need for heavy rolls.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional cylindrical wrapping material rolls are used, then wrapping material can be fed continuously, but the rolls are heavy and difficult to maneuver by operators

Engineering Contradiction:
Improveease of maneuvering wrapping materialVSAvoidweight of wrapping material roll
Core Design Contradiction:
Ease of operationVSWeight of moving object

Solution Approach 1:

The wrapping material is segmented into multiple individual sheets stacked together, replacing the single large cylindrical roll. Each sheet can be independently handled and positioned, dramatically reducing the weight and difficulty of maneuvering while maintaining continuous wrapping capability through the stacked arrangement.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The wrapping material is reconfigured from a three-dimensional cylindrical roll to a two-dimensional stacked arrangement of flat sheets. This dimensional change allows the material to be stored horizontally in a tray rather than vertically in a roll, reducing the height and weight that operators must handle while increasing storage capacity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Productivity

If cylindrical wrapping material rolls are used, then wrapping material can be fed continuously, but storage capacity is limited and downtime for reloading increases

Engineering Contradiction:

Solution Approach 1:

The wrapping material is segmented into multiple individual sheets stacked together, replacing the single large cylindrical roll. Each sheet can be independently handled and positioned, dramatically reducing the weight and difficulty of maneuvering while maintaining continuous wrapping capability through the stacked arrangement.

AI summary

The disclosure relates to a system and method for wrapping bales in a harvester (200) that uses wrapping material (606) stored in flat, folded layers instead of conventional round tubes or rolls, and specifically to a system for positioning and cutting the wrapping material during and after the process of wrapping a bale, the system comprising: a first feed roll (220), configured for dispensing a portion of wrapping material from a bundle (230); a feed plate system (500), configured to receive wrapping material and capable of applying a first amount of tension to the portion of wrapping material; and at least one cutting knife (604), positioned between the feed plate system and the bale chamber, such cutting knife independently movable from a first position to a second position; and a wrapping material channel positioned in operable communication with the bundle of wrapping material, the wrapping mechanism and the bale chamber.
