Baler Clutch Status Detection Using Output Shaft Speed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators of agricultural balers face challenges in determining when the clutch has disengaged, particularly in dusty conditions, which can lead to halted baling operations due to jamming or plugging.
Innovation Solution
A system and method that utilize sensors to generate data indicative of the rotational movement of the output shaft, which is then processed by a computing system to determine the rotational speed and identify when the clutch is in a disengaged position, allowing for automatic initiation of control actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If operators rely on visual cues to determine clutch status, then they can detect clutch disengagement, but dusty conditions reduce visibility and make detection difficult
Solution Approach 1:
The patent replaces visual detection methods with an automated sensor-based system. A sensor detects rotational movement of the output shaft, and a computing system processes this data to determine clutch status, eliminating reliance on operator vision in dusty conditions.
Solution Approach 2:
The patent introduces a sensor as an intermediary between the clutch mechanism and the operator. The sensor detects rotational movement and transmits this information to the computing system, which then determines clutch status, serving as a mediator that works independently of environmental conditions.
2Productivity
If the baler operates without automated monitoring, then the system remains simple, but operators cannot timely detect clutch disengagement, causing baling operations to halt
Solution Approach 1:
The system performs self-monitoring by automatically detecting clutch status through sensor data and computing system analysis. The baler monitors its own operational state without requiring external observation, enabling timely detection and response to clutch disengagement.
Solution Approach 2:
The patent implements a feedback loop where the sensor continuously monitors rotational movement, the computing system processes this data to determine clutch status, and this information can trigger alerts or automated responses. This closed-loop feedback system ensures continuous monitoring and timely detection of clutch disengagement.
3Loss of time
If operators manually monitor clutch status, then no automated systems are needed, but response time is delayed and operational efficiency is reduced
Solution Approach 1:
The sensor and computing system are pre-configured to continuously monitor rotational movement and automatically detect clutch disengagement as it occurs. This preliminary automated monitoring eliminates the need for operators to manually check status, providing immediate detection and response.

AI summary
A system for determining the clutch status of a baler includes a crop collector and a drive assembly configured to rotationally drive the crop collector. The drive assembly includes a drive shaft and an output shaft coupled between the crop collector and the drive shaft. The drive assembly also includes a clutch coupled between the drive shaft and the output shaft and moveable between an engaged position and a disengaged position to mechanically couple and decouple the drive shaft and the output shaft from each other. The system also includes a sensor configured to generate data indicative of a rotational movement of the output shaft. Furthermore, the system includes a computing system configured to determine a rotational speed of the output shaft based on the data generated by the sensor and determine when the clutch is in the disengaged position based on the determined rotational speed of the output shaft.
