Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing crimping systems for tobacco industry products result in non-uniformly compacted articles that tend to loosen during subsequent processes, leading to poor quality end products.
Innovation Solution
A crimping unit with a feed station equipped with dancer rollers for tensioning and a crimping station featuring adjustable crimping rollers and a supporting element that can modify the web's path, ensuring optimal compaction and uniformity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional crimping systems are used to create corrugations on the web, then the web can be compacted into a longitudinal stream, but the articles become non-uniformly compacted and tend to loosen
Solution Approach 1:
The crimping rollers are made adjustable in position and orientation through a supporting element that can be modified by motor means. This dynamic adjustment capability allows the crimping parameters to be optimized for different web types, achieving uniform compaction without loosening. The path along which the web is subjected to crimping action can be easily modified to adapt to specific web features.
Solution Approach 2:
The invention changes the parameters of the crimping process by allowing variable position and orientation of the crimping rollers. This enables optimization of the crimping action to achieve both uniform compaction and stable articles that do not loosen during subsequent processes.
2Manufacturing precision
If the crimping rollers are made adjustable to adapt to different web types, then the quality of end product is improved, but the device complexity increases
Solution Approach 1:
The supporting element with motor means provides multi-functionality by enabling both position and orientation adjustment of the crimping rollers. This single mechanism serves multiple purposes: adapting to different web types, optimizing crimping parameters, and ensuring high-quality end products, thereby managing complexity through universal design.
3Manufacturing precision
If the path of the web through the crimping rollers is modified to optimize compaction, then the web can be optimally compacted, but the device complexity increases
Solution Approach 1:
The path of the web through the crimping rollers is made dynamic and adjustable through the supporting element mechanism. This allows optimization of the compaction quality for different web types without requiring multiple fixed installations, managing complexity through a single adjustable system.
