Rotobaler Inclination Sensor Control for Safe Bale Deposition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The deposition of cylindrical bales on slopes is challenging, often requiring highly trained operators and risking bale damage or rolling down slopes, as existing technologies fail to ensure safe positioning without manual intervention.
Innovation Solution
A control arrangement with an inclination sensor generates signals to guide the vehicle's positioning or actuating arrangement, allowing for semi-automatic or fully automatic bale deposition that aligns with the slope's inclination, preventing rolling and ensuring safe placement without manual sliding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual intervention is used to position bales on slopes, then safe positioning can be achieved, but operator training requirements increase and operation complexity worsens
Solution Approach 1:
The system uses an inclination sensor to automatically detect the slope angle and control the deposit arrangement to position the bale safely without requiring operator intervention or specialized training. The system serves itself by using sensor data to make positioning decisions autonomously.
Solution Approach 2:
The patent replaces manual mechanical positioning with an automated control system that uses sensor data to control the deposit arrangement, substituting human operator skill with an automated sensing and control mechanism.
2Manufacturing precision
If manual sliding of bale is performed to correct position, then positioning can be adjusted, but bale damage risk increases
Solution Approach 1:
The inclination sensor detects the slope angle before the bale is deposited, and the control system pre-adjusts the deposit arrangement to the appropriate angle. This preliminary action ensures the bale is deposited in the correct position from the start, eliminating the need for subsequent manual sliding that could cause damage.
3Productivity
If bale is deposited without position control, then operation speed increases, but rolling down slope occurs
Solution Approach 1:
The inclination sensor continuously provides feedback about the slope angle to the control system, which automatically adjusts the deposit arrangement to maintain proper bale positioning. This closed-loop feedback ensures bale stability without requiring slow, controlled manual operation.
4Ease of operation
If automated control system is implemented, then operation ease improves, but device complexity increases
Solution Approach 1:
The control system integrates multiple functions into a single apparatus: the inclination sensor not only detects slope angle but also provides data to the control system which then controls the deposit arrangement positioning. This multi-functionality reduces the need for separate components and minimizes overall system complexity.

Data Source
AI summary
A rotobaler is provided with an inclination sensor that recognizes the inclination of the rotobaler, to the side as well as in the longitudinal direction. The inclination sensor generates a signal that is processed by a computer that controls a display arrangement in order to indicate whether a bale that is to be unloaded from the rotobaler can be ejected from the rotobaler, as presently positioned. If the inclination is such that a safe ejection of the bale is not possible, the computer sends out a signal that locks an outlet arrangement for the bale, or that steers the rotobaler in such a way that the bale is deposited with its longitudinal axis parallel to the inclination of the slope.
