Bale Storage Damper Assembly for Impact Energy Dissipation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bale storage systems face challenges in containing kinetic energy during the baling process, leading to impact forces and recoil oscillations that can cause damage to the storage devices and the bales themselves.
Innovation Solution
A bale collection system with a damper assembly that dissipates the kinetic energy of bales as they are loaded, using a combination of a pivotable arm and resistance members to control the bale's motion, allowing for efficient and safe loading without recoil oscillations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed fence or stop is used to contain the bale's kinetic energy, then the bale is contained in the storage device, but large impact forces are generated causing recoil oscillations and damage to the device
Solution Approach 1:
The damper assembly is positioned to engage the bale before it reaches the end of the storage device, providing progressive resistance that absorbs kinetic energy and prevents large impact forces on fixed fences. The damper's resistance members gradually decelerate the bale, cushioning the stopping process in advance of any hard contact.
Solution Approach 2:
The damper assembly acts as an intermediary between the moving bale and the fixed storage device structure. Rather than allowing direct contact between the bale and rigid fences, the damper's pivotable arm and resistance members provide a compliant interface that dissipates energy through controlled resistance.
2Productivity
If the bale is allowed to roll freely into the storage device, then loading is fast and efficient, but the kinetic energy causes recoil oscillations and damage
Solution Approach 1:
The damper assembly is designed with a pivotable arm that can dynamically adjust its position and resistance as the bale rolls through. The system transitions from a static fixed fence to a dynamic damping mechanism that adapts to the bale's motion, providing progressive resistance while maintaining high loading speeds.
Solution Approach 2:
The damper assembly changes the resistance parameter progressively as the bale moves through the storage device. Rather than providing constant rigid resistance, the damper's geometric relationship between the pivotable arm and resistance members creates variable resistance that increases as the bale decelerates, optimizing both loading speed and oscillation control.

AI summary
A bale collection system for use with a baler having an outlet through which a finished bale is ejected, the bale collection system including a holder coupled to the baler, the holder defining a support surface configured to support the finished bale, an operating barrier, and a holdback arm in operable communication with the holder and configured to 1) permit the finished bale to pass through the operating barrier in a first direction and 2) restrict movement of the finished bale through the operating barrier in a second direction, opposite the first direction.
