Round Baler Weight Control via Dynamic Pressure Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Round balers often produce bales with varying weights despite uniform diameters due to environmental conditions, which is disadvantageous in sales as customers prefer bales of uniform weight and diameter.
Innovation Solution
A round baler equipped with a chassis, a pressing chamber with variable diameter, a weight sensor device, and a control unit that regulates machine parameters such as pressing pressure to achieve bales of uniform weight and diameter by adjusting bale density and pressing pressure based on real-time weight and diameter measurements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the diameter of the bale is kept uniform, then the shape consistency is improved, but the weight uniformity deteriorates due to varying environmental conditions
Solution Approach 1:
The system uses a sensor device to measure the actual weight of the bale during formation and feeds this information back to the control unit. The control unit then adjusts the pressing pressure dynamically to compensate for weight deviations, ensuring uniform bale weight despite variations in material density caused by environmental conditions
Solution Approach 2:
The control unit dynamically changes the pressing pressure parameter based on real-time weight measurements. By adjusting this critical parameter, the system compensates for variations in material properties and environmental conditions, maintaining consistent bale weight while preserving uniform diameter
2Weight of moving object
If the pressing pressure is increased to increase bale density, then the bale weight is improved, but the energy consumption increases
Solution Approach 1:
Instead of applying maximum pressing pressure throughout the entire baling process, the system applies pressing pressure selectively and dynamically based on real-time weight measurements. The control unit adjusts the pressing pressure to the minimum necessary level required to achieve the target weight, avoiding excessive energy consumption while still achieving the desired bale weight and density
3Weight of moving object
If real-time weight measurement and control is implemented, then the bale weight uniformity is improved, but the device complexity increases
Solution Approach 1:
The control unit automatically adjusts the pressing pressure based on real-time weight measurements without requiring manual intervention. The system self-regulates by continuously monitoring bale weight through the sensor device and autonomously making corrections to maintain uniform weight, eliminating the need for operator judgment and reducing labor complexity

AI summary
A round baler (10) for forming a bale (B) that is at least substantially cylindrical is proposed, comprising a frame (14) supported on the ground (17) via a chassis (16) and a housing (12) with a pressing element (30) defining a pressing chamber (23) with a variable diameter, at least one first sensor device (70) for determining the weight of the bale (B), and a control unit (ECU) by means of which at least the diameter of a finished bale (B) can be specified, wherein the control unit (ECU) can also specify the weight of a finished bale (B) in addition to the diameter. Furthermore, a method for operating a round baler (10) is proposed.
