Bale Wrapping Leading Segment Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional balers require significant time for wrapping bales in wrapping material, leading to inefficiencies and potential mixing of wrapping material with loose material, which is undesirable for agricultural applications where precise bale size and minimal material mixing are crucial.
Innovation Solution
A bale forming and wrapping apparatus that forms a leading segment of the wrapping material outside the bale forming chamber and holds it in an intermediate position until the bale is fully formed, allowing for efficient injection of the wrapping material into the chamber only when the bale is ready, thereby reducing the distance the material needs to be conveyed and minimizing loose material injection during wrapping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the web of wrapping material is conveyed continuously from the supply reel to the wrapping material inlet, then the wrapping process can proceed without interruption, but the wrapping time increases significantly and loose material may mix with the wrapping material
Solution Approach 1:
The invention forms a leading segment of the web in advance (preliminary action) and positions it at the wrapping material inlet before the bale formation is complete. This allows the wrapping to start immediately when the bale is ready, without waiting for the web to be conveyed from the supply reel, thus reducing wrapping time while maintaining precise control over when wrapping begins relative to bale size
2Loss of time
If the web conveying is interrupted to form a leading segment in advance, then the wrapping time is reduced and material mixing is prevented, but additional control mechanisms are required
Solution Approach 1:
The invention introduces an intermediary mechanism (the leading segment positioning system) that decouples the web supply from the wrapping initiation. The leading segment acts as a buffer that can be prepared in advance and held ready, allowing the wrapping process to start immediately when the bale is formed without requiring continuous web conveyance or complex real-time synchronization
3Ease of operation
If the wrapping material inlet is positioned far from the supply reel, then the web can be supplied continuously, but the conveying distance increases wrapping time
Solution Approach 1:
The invention segments the web into two functional parts: a leading segment that is positioned in advance at the wrapping material inlet, and the remainder of the web that stays on the supply reel. This segmentation allows the leading segment to be ready immediately for wrapping while the rest of the web supply system can operate at its own pace, effectively eliminating the constraint of conveying distance

AI summary
An apparatus and a method for forming and wrapping a bale in a bale forming chamber into wrapping material includes a wrapping material conveying device that conveys a web of wrapping material towards a wrapping material inlet. A severing device severs the web at a severing location. The wrapping material conveying device moves the web towards the inlet, forms a leading segment of the web, and keeps the leading segment in an intermediate web providing position between the wrapping material inlet and the severing location without moving the leading segment. For starting the wrapping procedure, the web is conveyed towards the inlet.
