Round Baler Net Scraper for Wrap Trajectory Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing round baler systems face challenges in controlling the trajectory of wrap material, leading to misalignment and blockage during the wrapping process due to the wrap material not aligning with the inlet and potentially wrapping around spool rollers.
Innovation Solution
A scraper with an undulating edge is positioned on the outlet side of the nip between spool rollers, featuring peaks and valleys to guide the wrap material away from the first spool roller and direct it into the baling chamber, utilizing a resilient material to grasp and hook the mesh net wrap material if it gets stuck.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a pair of spool rollers is used to inject wrap material through the inlet into the baling chamber, then the wrap material can be fed into the baling chamber, but the wrap material trajectory cannot be controlled and may wrap around the spool rollers
Solution Approach 1:
A scraper element is introduced as an intermediary component between the spool rollers and the baling chamber inlet. This scraper acts as a mediator that guides the wrap material from the rollers toward the inlet, preventing the material from wrapping around the rollers while ensuring proper trajectory control and reliable feeding into the chamber.
2Adaptability or versatility
If the wrap material is very flexible to accommodate bale wrapping, then it can wrap around the bale effectively, but it becomes difficult to control the trajectory during insertion
Solution Approach 1:
The scraper element introduces local quality control at the critical interface between the spool rollers and the baling chamber inlet. By providing a localized guiding structure at this specific location, the flexible wrap material maintains its overall flexibility for bale wrapping while gaining localized trajectory control during insertion, resolving the contradiction between adaptability and ease of operation.

AI summary
A baler implement includes a wrap system having a first spool roller and a second spool roller arranged in parallel and positioned to form a nip therebetween. The first and second spool rollers are configured to receive a wrap material through the nip and discharge the wrap material from the nip toward an inlet of a baling chamber. A scraper is positioned on the outlet side of the nip adjacent to the first spool roller for guiding the wrap material away from a circumferential exterior surface of the first spool roller to prevent the wrap material from wrapping around the first spool roller. The scraper includes an undulating edge defining a plurality of peaks and a plurality of valleys with the plurality of peaks positioned proximate to the circumferential exterior surface of the first spool roller.
