Bale Wrapping Pivotable Roller Holder for Diameter Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bale wrapping devices require complex and time-consuming adjustments to accommodate bales of different diameters, often resulting in suboptimal alignment and increased operational complexity due to the need for varying support roller diameters or belt tension, which can lead to issues during the wrapping process.
Innovation Solution
A bale wrapping device with a pivotable support roller holder that adjusts the distance between support rollers, allowing the receiving table to adapt to different bale diameters without extensive redesign, ensuring the bale's center point remains aligned with the wrapping arm, thereby simplifying the adaptation process and maintaining consistent belt tension.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If support rollers with different diameters or increased horizontal distance between support rollers are used to accommodate different bale diameters, then the receiving table can be adjusted to different bale sizes, but the adjustment process becomes assembly-intensive and time-consuming
Solution Approach 1:
The support rollers are mounted on a pivotable holder that can be quickly repositioned between different angular positions, allowing the receiving table to dynamically adapt to different bale diameters without time-consuming assembly changes. The pivotable mechanism enables rapid adjustment by simply changing the angular position of the support rollers rather than replacing components.
Solution Approach 2:
The receiving table is segmented into a fixed support roller and a movable support roller holder that can be independently positioned. This segmentation allows the support rollers to be adjusted separately to accommodate different bale diameters, enabling quick adaptation without adjusting the entire table structure.
2Manufacturing precision
If belt tension is increased to raise the bale on changing tables with belts, then the bale can be supported at the correct height, but the contact surface of the bale on the belt is reduced, resulting in rotation of the bale during wrapping
Solution Approach 1:
The pivotable support roller holder acts as an intermediary mechanism that adjusts the vertical position of the bale by changing the angular position of the support rollers, rather than relying on belt tension. This mediator approach allows height adjustment while maintaining adequate belt contact and bale stability.

AI summary
A bale wrapping device (12) for wrapping a bale (28) with a wrapping material is presented. The bale wrapping device (12) comprises a receiving device (26) for receiving the bale (28) during wrapping and at least one wrapping arm (30). The receiving device (26) comprises a receiving table (36) with horizontally spaced support rollers (38, 40, 42) for supporting a bale (28), wherein a bale (28) can be supported by a first support roller (38) at a first circumferential point and optionally by at least a second or a third support roller (40, 42) at a second circumferential point spaced circumferentially from the first circumferential point, wherein a pivotable support roller holder (44) is included, on which the at least second and third support rollers (40, 42) are mounted, wherein the support roller holder (44) can be moved from a first position,The support roller (40) is pivotable into at least a second position in which the at least third support roller (42) assumes a support position for supporting a bale (28), such that by pivoting the support roller holder (44) from the first position to a second position, and vice versa, the distance (A1, A2) between the first support roller (38) and the second or third support roller (40, 42) in a support position can be changed. Furthermore, a harvesting device with such a bale wrapping device and a method using such a device are proposed.
