Agricultural Harvester Bale Wrap Feeding Assembly With Dynamic Rollers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural harvesters face challenges in efficiently feeding bale wrap to the bales during the wrapping process, which affects the operational efficiency and maintenance accessibility of the bale wrap feeding system.
Innovation Solution
A bale wrap feeding assembly with a frame that moves between feeding and loading positions, incorporating a fixed and movable feed roller system driven by a geared connection, allowing for efficient loading and maintenance of bale wrap, and utilizing a single motor to drive multiple rollers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed feed roller system is used to feed bale wrap, then the feeding process is stable, but the loading and maintenance accessibility is poor
Solution Approach 1:
The feed roller assembly is made movable relative to the frame, allowing it to transition between a first position during loading where the rollers are accessible, and a second position during operation where they perform the feeding function. This dynamic repositioning resolves the contradiction by providing stability during feeding while enabling accessibility during loading and maintenance.
2Adaptability or versatility
If multiple motors are used to drive the feed rollers, then each roller can be independently controlled, but the system complexity and energy consumption increase
Solution Approach 1:
Multiple feed rollers are driven by a single motor through a shared drive mechanism, eliminating the need for multiple independent motors. This merging of drive functions reduces system complexity and energy consumption while maintaining coordinated control of all rollers through the unified drive system.
3Productivity
If the feed rollers are positioned for optimal feeding, then the feeding efficiency is high, but the loading of bale wrap becomes difficult
Solution Approach 1:
The feed roller assembly can dynamically reposition between a feeding position optimized for high feeding efficiency and a loading position that provides easy accessibility for bale wrap loading. This dynamic positioning capability allows the system to achieve optimal feeding performance while eliminating loading difficulties through simple repositioning.

AI summary
A bale wrap feeding assembly for an agricultural harvester includes a frame configured to move with respect to a lateral axis of the agricultural harvester from a feeding position to a loading position. In addition, the bale wrap feeding assembly includes a fixed feed roller rotatably and non-movably coupled to the frame, and the bale wrap feeding assembly includes a movable feed roller rotatably and movably coupled to the frame. The movable feed roller is movable between an engaged position and a disengaged position relative to the fixed feed roller, the movable feed roller is configured to be positioned proximate to the fixed feed roller while in the engaged position, and the movable feed roller is configured to be positioned remote from the fixed feed roller while in the disengaged position.
