Round Baler Pressure Control via Position Sensors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing round balers face issues with overfilling, leading to bales that cannot be rotated or wrapped, resulting in disintegration and the need to re-form the material, due to increasing compression force as the bale grows and reaches its limits.
Innovation Solution
A system that uses sensors to monitor the relative position of bale-shaping elements, providing a binary or quantitative output to control the supply of crop and adjust baling pressure, ensuring the bale is wrapped before overfilling occurs, by integrating a baling pressure control system with hydraulic pistons and a control unit to manage the pressure and stop material intake when the limit is reached.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the bale chamber is filled to maximize material capacity, then the quantity of baled material increases, but the compression force increases abruptly causing the bale to become不可旋转 and无法包裹
Solution Approach 1:
The sensor detects the relative position of bale-shaping elements before overfilling occurs and triggers a warning signal or automatically stops material supply in advance, preventing the bale from reaching a state where it cannot be rotated or wrapped
Solution Approach 2:
The system uses sensors to continuously monitor the relative position of bale-shaping elements and provides feedback through warning signals or automatic control to stop material supply when the limit position is reached, maintaining optimal baling conditions
2Manufacturing precision
If the baling pressure is increased to maximize bale density, then the manufacturing precision of bale density improves, but the bale becomes difficult to rotate and wrap
Solution Approach 1:
The system dynamically adjusts baling pressure based on the detected relative position of bale-shaping elements, maintaining optimal pressure for density while automatically reducing pressure when the limit position is reached to enable easy rotation and wrapping
Solution Approach 2:
The system changes the baling pressure parameter in response to sensor feedback, adjusting pressure levels to maintain optimal density during normal operation and reducing pressure when overfilling is detected to facilitate bale handling
3Productivity
If the bale is allowed to grow beyond the chamber capacity, then the quantity of material processed increases, but the bale disintegrates and material must be re-formed
Solution Approach 1:
The sensor and control system detect and respond to the limit position before overfilling occurs, preventing bale disintegration and the need for re-forming by stopping material supply in advance
Solution Approach 2:
The continuous monitoring system provides real-time feedback on bale formation status and automatically stops material supply when the limit position is reached, preventing bale disintegration and ensuring reliable operation

Function Achieved in This Case
This solution reduces the risk of overfilling, allows for easier rotation and wrapping of the bale, and ensures optimal bale density by monitoring the filling status and adjusting the baling pressure, preventing material disintegration and the need for re-forming.
Implementation Method 1
a baling pressure control system which is coupled to the sensor to set different baling pressures depending on whether the relative position exceeds a predetermined limit position or not
Implementation Method 2
the compression force increases abruptly as material continues to be fed into the bale

AI summary
The round bale press (2) has two bale formation elements (3,3',3'') movable against each other in a degree of freedom and limit a press chamber (13). A sensor (20,24,25) is provided for detection of relative position of each other of the bale formation elements. The bale formation elements are connected with one another by a joint (7,12) in a tilted manner.
