Round Baler Feeding Device with Movable Carriage for Frictionless Roll Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for loading a new winding roll into a round baler's feed device are difficult and prone to damaging the winding material due to friction and impact, especially when using film-like materials.
Innovation Solution
A feed device with a running carriage mounted on a rail parallel to the support rollers allows the winding roll to be moved into the roll holder without frictional contact, and a pivoting device enables the support rollers to be positioned away from the braking roller during loading, reducing the risk of damage and making the process easier.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the winding roll is manually pushed into the roll holder from the loading device, then the loading process can be completed, but the winding material is damaged due to friction and impact
Solution Approach 1:
A running carriage is introduced as an intermediary device between the loading arm and the roll holder. The winding roll is mounted on the carriage and moved along a running rail, allowing frictionless transfer without direct contact between the winding material and the roll holder or support rollers, thus preventing damage while maintaining ease of operation
Solution Approach 2:
The loading process is segmented into distinct phases: positioning the winding roll on the loading arm, transferring it to the running carriage, moving the carriage along the rail, and finally receiving the roll in the roll holder. This segmentation allows each phase to be optimized independently, reducing overall damage risk
2Device complexity
If the support rollers are positioned close to the braking roller during loading, then the roll holder structure is compact, but the winding material is at risk of hitting corners and edges
Solution Approach 1:
The support rollers are made dynamically positionable relative to the braking roller. During loading operations, the support rollers can be repositioned to a loading position that provides a safety margin from the braking roller, preventing contact with corners and edges. During normal operation, they return to their working position for compact structure
Solution Approach 2:
Before the winding roll is transferred to the roll holder, the support rollers are preliminarily positioned in a safe configuration away from the braking roller. This preliminary positioning prevents potential damage before it can occur, allowing the roll to be safely received without risk of hitting sharp edges
