Baling Press Slope Compensation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Baling presses face challenges in wrapping bales on uneven terrain due to bale misalignment and slippage, leading to disruptions in the wrapping process, and existing solutions either compromise machine design or fail to address slope gradients effectively.
Innovation Solution
A baling press with a control device that adjusts the speed and acceleration of working tools and a slope compensation device that tilts and adjusts the position of functional units to match the slope, ensuring stable bale transfer and wrapping, even on steep slopes, without sacrificing a compact machine design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a transfer conveyor is provided to convey bales from the bale forming chamber to the wrapping table, then the bale transfer is improved, but the machine becomes bulky and expensive in the longitudinal direction
Solution Approach 1:
The patent removes the transfer conveyor from the system by directly coupling the bale forming chamber to the wrapping table. The bale is ejected directly onto the wrapping table without an intermediate transfer mechanism, thereby simplifying the machine structure while maintaining reliable bale transfer.
Solution Approach 2:
The patent merges the bale forming chamber and wrapping table into a closely integrated arrangement where the bale ejection point is directly adjacent to the wrapping table. This eliminates the need for a separate transfer conveyor and reduces the longitudinal dimension of the machine.
2Adaptability or versatility
If the wrapping table is tilted to compensate for slope, then wrapping on uneven terrain is improved, but only slope gradients in the direction of travel can be compensated
Solution Approach 1:
The patent employs dynamic speed and acceleration control of the wrapping table and working tools based on real-time slope detection. The control device adjusts operational parameters adaptively to compensate for both longitudinal and transverse slope effects without requiring mechanical tilting of the wrapping table.
Solution Approach 2:
The patent changes the operational parameters (speed and acceleration) of the wrapping table and working tools according to the detected slope conditions. This allows compensation for various slope gradients by dynamically adjusting motion parameters rather than relying solely on mechanical tilting.
3Productivity
If the working speed of the wrapping table is increased to maintain performance on slopes, then productivity is improved, but bale slippage and misalignment increase
Solution Approach 1:
The patent uses dynamic speed and acceleration control where the wrapping table and working tools adjust their motion parameters based on real-time slope detection. This allows the system to maintain high productivity on level ground while automatically reducing speed and acceleration on slopes to prevent bale slippage and misalignment.
Solution Approach 2:
The patent incorporates a slope detection device that provides feedback to the control device, which then adjusts the working speed and acceleration accordingly. This closed-loop control ensures that productivity is maintained when conditions permit while preventing slippage and misalignment when slope conditions require reduced speed.

AI summary
The present invention relates to a baler comprising a chassis for ground support, a collector for gathering crop material from the ground, a bale former for forming the gathered crop material into bales, and a wrapper for wrapping the bale with a net, film, or the like. According to the invention, the baler is characterized by a determining device for determining the slope and/or inclination of the baler relative to a target orientation when resting on a horizontal ground surface, as well as a control device for controlling the working speed and/or acceleration of at least one working tool of the bale former and/or the wrapper and/or a transfer conveyor provided between the wrapper and the bale former, depending on the determined slope and/or inclination.
