Pivotable Roller Conveyor for Gentle Bale Unloading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bale transport vehicles face challenges in safely and gently loading and unloading round bales, particularly silo bales, due to the risk of damaging the bale cover and the bales rolling during transport, which can lead to accidents.
Innovation Solution
A bale transport wagon equipped with a roller conveyor having a pivotable section that aligns transversely to the direction of travel, combined with a lifting device that interacts with the pivotable section for both loading and unloading, ensuring secure handling and support for bales of varying sizes through a V-shaped design with driven rollers and a telescopic arm for precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If bales are unloaded by raising the loading area to the rear or tilting to the side, then unloading is achieved, but the bale cover may be damaged and the bale may roll causing accidents
Solution Approach 1:
A laterally pivotable boom with a roller conveyor acts as an intermediary between the main loading area and the ground. The boom receives bales from the roller conveyor, transports them laterally, and deposits them gently on the ground, avoiding direct dropping or tilting that could damage the bale cover or cause rolling accidents
Solution Approach 2:
The boom is designed to be laterally pivotable, allowing dynamic adjustment of the unloading position. The roller conveyor on the boom can also pivot, enabling flexible adaptation to different unloading locations while maintaining gentle bale handling throughout the process
2Ease of operation
If a lever arm pushes the bale off the side for unloading, then unloading is achieved, but the bale is pressed over a small area causing damage
Solution Approach 1:
The roller conveyor on the pivotable boom serves as an intermediary that receives bles from the main loading area and gently deposits them on the ground through lateral movement, eliminating the need for lever arm pushing that concentrates force on a small area
Solution Approach 2:
The dynamic lateral pivoting of the boom and roller conveyor enables gentle bale transfer through controlled movement, distributing forces evenly across the bale surface rather than concentrating pressure on a small contact area
3Stability of the object's composition
If the roller conveyor is fixed in the longitudinal direction, then transport stability is achieved, but the lifting device cannot effectively load and unload bales
Solution Approach 1:
The roller conveyor system is segmented into a fixed main section for stable transport and a separate pivotable boom section for flexible loading and unloading operations, allowing each section to perform its specialized function optimally
Solution Approach 2:
The pivotable boom with roller conveyor provides dynamic flexibility for loading and unloading operations, while the fixed main roller conveyor maintains transport stability, combining both requirements through modular design

Function Achieved in This Case
This solution allows for safe, targeted, and gentle handling of bales during loading and unloading, preventing damage to the bale cover and reducing the risk of accidents by providing lateral support and secure transfer of bales onto and off the vehicle.
Implementation Method 1
a roller conveyor (3), the longitudinal axes of the rollers (6) of the roller conveyor (3) being arranged transversely to the direction of travel of the ball transport vehicle (1)

AI summary
The invention relates to a bale transport cart (1) comprising a loading platform with a roller conveyor (3), wherein the bale transport cart (1) has a lifting device (2) laterally for loading bales, wherein the part of the roller conveyor (3) on which the lifting device (2) is located laterally is a pivotable section (8) of the roller conveyor (3) which can be pivoted by means of a pivoting device (7) in the direction in which the lifting device (2) is located. Advantageously, this achieves the effect that round bales (21) can be unloaded from the bale transport cart (1) with the lifting device (2) by pivoting the pivotable section (8) of the roller conveyor (3) in the direction of the lifting device (2).
