Wrap Device for Round Module Builder
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing round module builders face challenges in efficiently and effectively wrapping bales to maintain a compacted state, as existing solutions often result in bunched or folded wraps, increasing weight, cost, and complexity, and causing soil compaction and stress on the chassis.
Innovation Solution
A wrap device with a wrap floor comprising a first and second portion, coupled by a linkage, featuring sheaves and an actuator to move the wrap floor from a disengaged to an engaged position, ensuring the wrap is accurately communicated to the bale chamber, with a yieldable bias to guide and tension the wrap for a tightly wrapped module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If existing wrap devices are used to wrap bales, then wrapping function is provided, but wrap placement accuracy deteriorates causing bunched or folded wraps
Solution Approach 1:
The wrap floor is made movable between engaged and disengaged positions through a linkage system with an actuator. This dynamic positioning allows the wrap floor to be precisely positioned during wrapping operations to ensure accurate wrap placement, then moved to a disengaged position to prevent wrap bunching or folding. The dynamic adjustment resolves the contradiction by providing both precision during operation and reliability in wrap quality.
Solution Approach 2:
The wrap floor acts as an intermediary element between the wrap source and the bale chamber. It mediates the wrap delivery process by controlling wrap release and positioning, ensuring accurate wrap placement on the module while preventing wrap defects. This intermediary mechanism improves both wrap placement accuracy and wrap quality reliability.
2Productivity
If wrap floor is continuously engaged to communicate wrap, then wrap delivery is continuous, but wrap bunching or folding occurs increasing weight and complexity
Solution Approach 1:
The wrap floor dynamically transitions between engaged and disengaged positions to control wrap delivery. It engages to deliver wrap continuously during the wrapping cycle, then disengages to allow the wrap to be properly positioned and tensioned, preventing bunching or folding. This dynamic operation maintains productivity while preventing excessive wrap weight from defects.
Solution Approach 2:
The wrap floor operates in periodic cycles of engagement and disengagement synchronized with the wrapping process. During engagement, wrap is delivered continuously; during disengagement, the system allows for wrap positioning and tensioning. This periodic action ensures continuous productivity while preventing wrap bunching or folding that would increase weight.
3Strength
If excessive wrap is applied to maintain compaction, then module compaction is improved, but chassis stress and soil compaction increase
Solution Approach 1:
The wrap floor linkage system includes yieldable bias elements that provide feedback on wrap tension and positioning. This feedback mechanism ensures that wrap is applied with appropriate tension to achieve module compaction without excessive force, preventing both insufficient compaction and excessive chassis stress or soil compaction. The system self-regulates wrap application force based on real-time conditions.
Solution Approach 2:
The wrap floor linkage with yieldable bias automatically adjusts wrap tension and positioning during the wrapping process. The system self-regulates to apply the minimum necessary wrap tension to achieve proper module compaction, preventing excessive force application that would increase chassis stress or soil compaction while maintaining adequate Strength for compaction.

AI summary
A wrap device for communicating a wrap to a bale chamber of a round module builder. The round module builder comprises a bale sheave for driving a bale belt to wrap a round module with the wrap. The wrap device comprises a wrap floor. A wrap floor linkage couples the wrap floor to the round module builder. A first sheave and a second sheave are coupled to the wrap floor. A wrap floor belt is supported by the first and second sheaves. An actuator is coupled to at least one of the wrap floor linkage and the wrap floor to move the wrap floor from a disengaged position to an engaged position. In the disengaged position, the wrap is not communicated to the bale chamber. In the engaged position, the wrap floor belt engages the bale belt and communicates the wrap to the bale chamber.
