Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current reel handling processes for cardboard reels in manufacturing lines are labor-intensive and time-consuming, requiring manual rewinding to change winding directions, which poses safety concerns and limits efficiency.
Innovation Solution
An automated reel handling machine with re-reeling assemblies, a reel manipulator, and integrated mechanisms for taping and labeling, enabling automated unwinding and rewinding of product strips onto reels, and transferring them to remote locations for further processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual rewinding is used to change winding direction, then flexibility in winding orientation is achieved, but labor intensity and time consumption increase significantly
Solution Approach 1:
The system uses the product strip itself as the actuating force to automatically rewind reels. The strip feeds from source reels and winds onto target reels through guide rollers and tensioning mechanisms, eliminating the need for external manual intervention while maintaining adaptability to different winding directions through programmable path configuration
Solution Approach 2:
The system dynamically configures re-reeling paths by selectively engaging guide rollers and adjusting tensioning points based on the desired winding direction. The manipulator arm moves dynamically to position reels and adjust strip routing, enabling flexible adaptation to different machine requirements without fixed mechanical constraints
2Ease of operation
If manual handling is used for reel operations, then operational flexibility is maintained, but safety risks and labor requirements increase
Solution Approach 1:
The system replaces manual mechanical handling with an automated manipulator arm equipped with grippers that mechanically transfer and position reels. The strip feeding and winding processes are controlled by automated tensioning mechanisms and guide rollers, eliminating human exposure to moving parts and heavy reel handling while maintaining operational flexibility through programmable control
Solution Approach 2:
The manipulator arm serves as an intermediary between the reel storage area and the re-reeling station, performing all intermediate handling operations including reel pickup, positioning, and replacement. This intermediary mechanism isolates human operators from direct contact with moving reels and strip tensioning mechanisms, eliminating safety hazards while preserving operational flexibility
3Productivity
If automated re-reeling is implemented, then productivity and throughput increase, but system complexity increases
Solution Approach 1:
The manipulator arm performs multiple functions including reel pickup, positioning on mounts, adjustment of strip routing, and replacement of depleted reels. The same mechanical system handles both clockwise and counterclockwise winding configurations, eliminating the need for separate dedicated mechanisms for each operation and reducing overall system complexity despite high productivity requirements
Solution Approach 2:
The automated system is segmented into independent functional modules: reel storage stations, manipulator arm with grippers, re-reeling assemblies with guide rollers, and tensioning mechanisms. Each module operates semi-independently and can be controlled separately, allowing for easier maintenance, troubleshooting, and scalability while achieving high throughput through coordinated operation of all segments

AI summary
A reel handling machine includes first and second re-reeling assemblies coupled to a frame. The re-reeling assemblies each include a reel mount supporting a first reel and a re-reel mount supporting a second reel. The re-reeling assemblies operated to unwind a product strip from the first reel and rewind the product strip on the second reel. The reel handling machine includes a reel manipulator positioned proximate to the re-reeling assemblies configured to automatically remove the second reel from the re-reel mount after the product strip is rewound on the second reel and move the second reel to a remote location.
