Rotating Bale Wrap Mounts for Continuous Harvester Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural harvesters face challenges in efficiently loading and switching between multiple bale wrap assemblies during the bale wrapping process, leading to inefficiencies and potential disruptions in the bale formation and wrapping operations.
Innovation Solution
A bale wrap assembly loading system with a storage compartment that includes a frame and a rotatable bale wrap support, featuring first and second mounts on opposite sides of a pivot point, and a controller to orient the support at specific angles for loading and switching bale wrap assemblies, facilitated by actuators and an arm for movement and engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single bale wrap assembly is used in the bale wrapping system, then the system structure is simple, but the system experiences downtime when the wrap is depleted and requires manual reloading
Solution Approach 1:
The bale wrap support is divided into multiple segments or mounts (first bale wrap mount, second bale wrap mount, etc.) arranged around a pivot point. Each mount can independently hold a bale wrap assembly, allowing the system to segment the wrapping function across multiple units rather than relying on a single assembly.
Solution Approach 2:
The bale wrap support is designed to be rotatable about a pivot point, transitioning between a first position where the first bale wrap assembly is accessible and a second position where the second bale wrap assembly is accessible. This dynamic positioning allows automatic switching between multiple wrap assemblies without manual intervention, maintaining continuous operation.
2Productivity
If manual loading and switching of bale wrap assemblies is performed, then the system structure is simple, but loading efficiency is reduced and downtime increases
Solution Approach 1:
Multiple bale wrap assemblies are pre-loaded onto the rotatable bale wrap support structure at different mounts before the wrapping operation begins. The controller is pre-programmed with the sequence of positions, enabling automatic switching between assemblies without manual intervention during operation.
Solution Approach 2:
The system includes sensors that detect the position of the bale wrap support and the status of each bale wrap assembly. This feedback information is communicated to the controller, which automatically determines when to switch between assemblies and controls the rotation to the appropriate position, enabling automated operation.
3Reliability
If multiple bale wrap assemblies are stored and switched manually, then wrap availability is improved, but operational complexity and downtime increase
Solution Approach 1:
The rotatable bale wrap support structure serves multiple functions: it stores multiple bale wrap assemblies simultaneously, automatically positions them in sequence, and integrates with the controller to manage the switching process. This multi-functional design eliminates the need for separate manual loading and switching operations.
Solution Approach 2:
The system enables self-service operation where the controller automatically manages the switching between bale wrap assemblies based on sensor feedback. The rotatable support self-positions to bring the next wrap assembly into the loading position without requiring manual intervention, making the system operate autonomously.

AI summary
A bale wrap assembly loading system for an agricultural harvester includes a storage compartment configured to store bale wrap assemblies. The storage compartment includes a frame, a bale wrap support rotatably coupled to the frame at a pivot point, a first bale wrap mount coupled to the bale wrap support and configured to support one or more first bale wrap assemblies, and a second bale wrap mount coupled to the bale wrap support and configured to support one or more second bale wrap assemblies. The bale wrap support is configured to rotate about the pivot point to orient the bale wrap support at a first loading angle to facilitate receiving the one or more first bale wrap assemblies at a loading location and to orient the bale wrap support at a second loading angle to facilitate receiving the one or more second bale wrap assemblies at the loading location.
