Capsule Insertion Wheel Cam Mechanism for Filter Tow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for imparting flavor to cigarette smoke through filter capsules are inefficient in ensuring consistent and uniform distribution of flavorings within the filter tow, leading to variations in smoking experience.
Innovation Solution
An apparatus comprising a tow processing unit coupled with a capsule insertion unit and a filter rod making unit, featuring a feeder wheel with radial grooves and an insertion wheel with recesses, synchronized by cam mechanisms to ensure precise and regular insertion of capsules into the filter tow, utilizing an endless belt and vacuum assistance for efficient capsule distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If capsules are inserted into filter tows using existing methods, then flavor can be imparted to cigarette smoke, but the distribution of flavorings is inconsistent and non-uniform
Solution Approach 1:
The insertion mechanism is divided into multiple functional components: a feeder wheel with radial grooves for capsule storage and positioning, an insertion wheel with recesses for capsule reception, and cam mechanisms for synchronized actuation. This segmentation allows precise control over capsule placement at specific intervals along the filter tow, ensuring uniform distribution.
Solution Approach 2:
Capsules are pre-positioned in radial grooves on the feeder wheel before insertion, and the cam mechanisms are pre-configured to actuate pins at specific points along the circumference. This preliminary arrangement ensures that capsules are ready for immediate insertion at the correct positions, achieving consistent and uniform distribution without requiring complex real-time control.
2Manufacturing precision
If a complex capsule insertion mechanism is used, then capsule distribution can be improved, but the device complexity increases
Solution Approach 1:
The feeder wheel and insertion wheel are merged into a single integrated assembly that rotates together, sharing a common rotational axis. The cam mechanisms are integrated into the wheel structure itself rather than being separate external components. This merging reduces the number of independent moving parts while maintaining precise capsule insertion capability.
Solution Approach 2:
The radial grooves on the feeder wheel serve multiple functions: they store capsules, position them for insertion, and facilitate their transfer to the insertion wheel. The recesses on the insertion wheel similarly serve as both storage and insertion points. This multi-functionality reduces the need for separate components, simplifying the overall device while maintaining precision.
