Counter-Rotating Rollers for Optical Lens Packaging Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for removing thin-walled packaging wrappers from optical lenses are labor-intensive, prone to errors, and inefficient, particularly when dealing with creased or air-permeable materials.
Innovation Solution
An unpacking device featuring counter-rotating rollers that create an intake gap to grip and pull the packaging wrapper off the optical lens, allowing for rapid and reliable removal without the need for manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If suction cups are used to fix and tear open packaging wrappers, then automated removal is achieved, but reliability deteriorates with creased or air-permeable materials
Solution Approach 1:
The patent replaces the pneumatic suction cup system with a mechanical roller-based system. Two rollers rotate in opposite directions to create friction-based gripping and pulling forces that reliably strip the packaging wrapper from the workpiece, eliminating the unreliability of suction cups with creased or air-permeable materials.
Solution Approach 2:
The invention changes the fundamental operating parameters from pneumatic suction to mechanical friction-based gripping. The rollers are driven to rotate at controlled speeds creating sufficient friction force to grip the wrapper material and pull it off the workpiece, providing consistent performance across different material types.
2Reliability
If circumferential cutting is performed to remove wrappers, then removal is achieved, but processing speed deteriorates becoming the bottleneck
Solution Approach 1:
The patent replaces the cutting-based mechanical system with a friction-based roller system. The rollers grip the wrapper and pull it off in one continuous motion, eliminating the time-consuming cutting and separation steps that create the productivity bottleneck.
Solution Approach 2:
The invention skips the intermediate cutting step entirely. The rollers directly grip the wrapper and pull it off the workpiece in a single rapid operation, rushing through the removal process without the delays inherent in cutting, folding, and separating operations.
3Adaptability or versatility
If manual unpacking is performed, then flexibility is maintained, but labor costs and monotony increase
Solution Approach 1:
The system is designed to automatically adapt to different workpiece and wrapper configurations through the inherent flexibility of the roller mechanism. The rollers self-adjust to grip various wrapper types and sizes without requiring manual intervention, providing both automation efficiency and adaptability.

AI summary
The invention relates to an unpacking device (30) which is designed to remove a thin-walled packaging wrapper (10) from a workpiece (1), having a processing station (P) having a workpiece receptacle (31) for receiving the workpiece (1), and having a pair of counter-rotating rollers (40, 41) which are mounted so as to be rotatable about counter-rotating axles (GA1, GA2) and between which is formed an intake gap (42). At least one of the counter-rotating rollers (40, 41) is driven so as to rotate about its counter-rotating axle (GA1, GA2) by a drive (43), the pair of counter-rotating rollers (40, 41) being disposed on a circumference (U) of the processing station (P) in such a manner and designed to induct the thin-walled packaging wrapper (10) into the intake gap (42). Moreover, the invention relates to a processing device having such an unpacking device 30, and to an unpacking method.
