Baler Discharge Unit Control via Acceleration Sensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing balers require stopping and waiting for the bale to be completely unloaded and the discharge unit to close before moving, resulting in significant time loss due to the need for manual sensing of the discharge unit's position.
Innovation Solution
A baler equipped with an acceleration sensor that controls the discharge unit's movement based on acceleration signals, allowing for automatic and efficient unloading and re-closure, reducing waiting time and improving operational efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the discharge unit is moved manually with position sensing, then the bale can be completely unloaded, but significant time is lost due to waiting for unloading and re-closure
Solution Approach 1:
The patent replaces the mechanical position sensing system (switches or inductive sensors detecting discharge unit position) with an acceleration sensor that detects bale unloading through acceleration signals. This substitution eliminates the need to wait for mechanical position confirmation, as the control unit can detect bale movement and initiate re-closure based on acceleration patterns, significantly reducing waiting time while ensuring complete unloading
Solution Approach 2:
The patent implements a feedback mechanism where the acceleration sensor continuously monitors bale movement and provides real-time acceleration signals to the control unit. The control unit processes these signals to determine when the bale has been fully unloaded and when to initiate re-closure of the discharge unit, creating a closed-loop system that optimizes the unloading-closure cycle without manual intervention or mechanical position sensing
2Ease of operation
If the discharge unit remains open for complete unloading, then the bale can be fully discharged, but the baler must stop and wait before moving again
Solution Approach 1:
The patent enables preliminary action by using the acceleration sensor to detect bale movement and initiate re-closure of the discharge unit before the bale is completely unloaded. The control unit processes acceleration signals to determine optimal re-closure timing, allowing the discharge unit to close earlier in the unloading process rather than waiting for complete discharge, thus reducing stopping time and improving operational efficiency while maintaining complete bale discharge
Solution Approach 2:
The patent implements self-service by automating the discharge unit control through the acceleration sensor and control unit system. The system automatically detects bale unloading progress through acceleration signals and autonomously initiates re-closure without operator intervention, eliminating the need for manual position sensing and enabling the baler to continue moving sooner, thereby improving productivity while ensuring complete discharge

AI summary
A baler includes a discharge unit moveable between a first position, in which a baling chamber is closed, and a second position, in which the baling chamber is open for unloading of the bale. A control unit is configured to control an actuator to move the discharge unit between the first position and the second position. An acceleration sensor is arranged to sense an acceleration of the baler. The control unit is in communication with the acceleration sensor, and is operable to control movement of the discharge unit based on acceleration of the baler detected by the acceleration sensor.
