Baling Press Starter Roller Segmentation for Bale Formation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing balers face issues with irregular bale formation and overload of rear drive elements due to the shifting center of gravity of the bale, leading to insufficient wrapping effect and excessive load on the tailgate area.
Innovation Solution
The implementation of multiple starter rollers arranged in a sequential manner within the bale-forming chamber, ensuring continuous engagement and driving functionality as the bale grows, combined with a wrapping device using adjustable tensioning arms for the belt, to maintain uniform bale formation and distribute load effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single starter roller is used in the transition area, then the initial material conveyance is improved, but the driving function decreases as the bale grows and shifts center of gravity
Solution Approach 1:
The single starter roller is divided into multiple starter rollers (at least two) arranged one behind the other in the infeed direction. This segmentation ensures that as the bale grows and shifts position, at least one starter roller remains in sufficient engagement with the bale to maintain the driving function throughout the entire bale formation process.
2Device complexity
If the bale chamber is fixed, then the structure is simpler, but the load on tailgate and rear drive elements increases excessively
Solution Approach 1:
Multiple starter rollers are positioned at specific locations (lower edge area and/or upper edge area of the bale-forming chamber adjacent to the feed channel) to create localized driving zones. This distribution of driving functions reduces the concentrated load on the tailgate and rear drive elements while maintaining effective bale formation.
3Reliability
If multiple starter rollers are arranged sequentially, then the driving function is maintained throughout bale growth, but the device complexity increases
Solution Approach 1:
The starter rollers are designed to be driven (rotatable) rather than fixed, allowing them to adapt dynamically to the growing bale's position and size. This dynamic configuration maintains optimal engagement throughout the bale formation process without requiring excessive numbers of rollers.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution ensures reliable and uniform bale formation by maintaining consistent driving function and pressure distribution, preventing overloading and irregularities, while allowing for efficient bale shaping and compression.
Implementation Method 1
at least two driven starter rollers (5, 6) arranged one behind the other in the infeed direction (12) of the crop (20) into the bale-forming chamber (2)
Implementation Method 2
a wrapping device (20) with a wrapping means (21) encircling the bale (1) to be formed is provided
Implementation Method 3
The mentioned wrapping means (21) is guided over several deflection rollers (3, 4) and, if necessary, driven by them

AI summary
The present invention relates to a baler with a preferably fully or partially variable bale forming chamber (2) in which stalk- and/or leaf-shaped harvested material or similar material for pressing can be formed and/or pressed into bales, wherein the harvested and/or pressed material can be fed into the bale forming chamber (2) through a feed channel (11) opening into the bale forming chamber, in which a conveying and/or cutting device (15) is arranged, wherein at least one driveable starter roller (5, 6) is provided in the transition area between the feed channel and the bale forming chamber for starting the bale forming process. According to the invention, the baler has at least two stationary starter rollers (5) arranged one behind the other in the direction of entry of the harvested material, at least one of which is designed to be driveable.
