Binding Device for Sun-Blind Lamella Packs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machines for producing sun-blind lamellas face challenges in binding packs of varying lengths and quantities without re-setting, which can lead to disintegration during handling.
Innovation Solution
A binding device with a storage tank for binding tapes, leader pulleys, and pneumatic welding jaws that allows for automatic binding on the stacking frame, enabling secure packaging without adjustments, using a reel with double binding tapes and triple pulleys for smooth tape alignment and welding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If binding is performed after take-away from stacking frame, then binding quality is improved, but handling time and productivity are reduced
Solution Approach 1:
The binding device performs preliminary binding action on the stacking frame before the pack is taken away. The binding tapes are fed through the lamella pack and welded in position while the pack is still on the stacking frame, eliminating the need for post-take-away binding operations.
Solution Approach 2:
The patent introduces a binding device as an intermediary system between the stacking frame and the take-away process. This device includes binding tape storage, feeding mechanisms, and welding jaws that operate independently to secure the pack during stacking, allowing subsequent handling without disintegration risks.
2Manufacturing precision
If binding device is designed for specific pack dimensions, then binding quality is improved, but adaptability to different pack sizes is reduced
Solution Approach 1:
The binding device incorporates adjustable and movable components that can adapt to different pack dimensions. The binding tapes are fed dynamically through the pack, and the welding jaws can position themselves appropriately regardless of the specific number or length of lamellas in the pack.
Solution Approach 2:
The binding device is designed as a universal system that can handle packs of varying sizes and configurations. The same device structure and binding mechanism work effectively whether the pack contains few short lamellas or many long ones, eliminating the need for re-setting.
3Ease of manufacture
If binding device structure is simplified, then ease of manufacture is improved, but binding quality and reliability are reduced
Solution Approach 1:
The binding device employs self-aligning and self-adjusting mechanisms that eliminate the need for complex precision adjustments. The binding tapes automatically feed through the pack, and the welding jaws self-position to ensure proper binding without requiring elaborate calibration or complex mechanical linkages.
Solution Approach 2:
The device utilizes pneumatic cylinders to drive the welding jaws and control the binding tape feeding mechanism. This pneumatic actuation provides reliable, consistent force for welding and tape advancement while maintaining a relatively simple mechanical structure compared to purely mechanical drive systems.
