Web Injection Clamping Mechanism for Round Baler Wrapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wrapping material supplying systems for agricultural round balers face challenges in ensuring reliable injection of the web into the bale forming chamber, particularly when the system is subjected to vibrations, wind, or varying inclinations, leading to potential misalignment and improper wrapping.
Innovation Solution
A wrapping material supplying apparatus featuring a holding member and a conveying member with notches and pressing elements that engage to clamp and guide the web into the chamber, ensuring proper alignment and injection, even in challenging environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional web conveying system is used, then the web can be supplied to the chamber, but the web may become misaligned due to vibrations, wind, or varying inclinations
Solution Approach 1:
The pressing element is positioned specifically at the front edge of the conveying member to provide localized clamping force on the web. This localized action ensures the web remains properly aligned at the critical injection point while allowing the rest of the system to remain simple and unaffected by environmental factors.
Solution Approach 2:
The pressing element pre-clamps the web at the front edge of the conveying member before injection occurs. This preliminary clamping action prevents misalignment from vibrations, wind, or inclinations during the web conveyance and injection process, ensuring reliable web positioning.
2Reliability
If the pressing element width equals the holding member width, then the web is clamped across the full width, but the clamping effectiveness is reduced
Solution Approach 1:
The pressing element has a width smaller than the holding member, concentrating the clamping force on a specific portion of the web at the front edge. This localized clamping is more effective than distributed clamping across the full width, as it creates sufficient friction and mechanical engagement to prevent web slippage and misalignment during injection.
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
The apparatus effectively reduces the risk of web misalignment and improves the clamping effect, ensuring reliable wrapping of bales across different materials and environmental conditions.
Implementation Method 1
The or at least one pressing element presses a part of the web positioned between the holding member and the conveying member through the notch positioned vertically adjacent to this pressing element

AI summary
The invention refers to a wrapping material supplying apparatus and device which supplies a web (21) of wrapping material to a chamber (Ch) which contains an object (B) to be wrapped. A protruding segment (Sg) of the web (21) is clamped between a conveying member (3) and a holding member (2) and is moved towards a wrapping material inlet (In). A pressing element (4.4) is mounted at the front edge (FE.3) of the conveying member (3) and engages into a notch (5.4) which is cut into the front edge of the holding member (2). The pressing element (4.4) presses the web (21) through the notch (5.4).
