Vacuum Capsule Filling Station for Precise HNB Substrate Packing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for filling aerosol-forming substrates into heat-not-burn (HNB) aerosol-generating capsules are inefficient and lack precision, particularly in ensuring proper orientation and filling of capsule casings, leading to potential defects and inconsistencies.
Innovation Solution
A filling station with a filling receptacle, carriages, and vacuum ports, along with optional baffles and a motor for vibration, is designed to rotate and axially move capsule casings, utilizing vacuum to fill the substrates efficiently and enhance packing density, while baffles modify substrate distribution for precise filling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual or simple mechanical filling processes are used, then device complexity is reduced, but manufacturing precision and filling consistency deteriorate
Solution Approach 1:
The filling system is segmented into multiple functional components: a filling receptacle with vacuum ports for substrate distribution, multiple carriages with vacuum ports for capsule engagement, and a vacuum source. This segmentation allows each component to perform a specific function, achieving precise and consistent filling while maintaining manageable system complexity through modular design.
2Quantity of substance
If vacuum filling is used, then packing density is improved, but energy consumption increases
Solution Approach 1:
The system employs pneumatic principles by using a vacuum source connected to vacuum ports in the filling receptacle and carriages. The vacuum pressure draws the aerosol-forming substrate into the capsule casings, achieving high packing density without requiring mechanical compression or excessive energy input, thus efficiently resolving the trade-off between packing density and energy consumption.
3Manufacturing precision
If capsule casings are not properly oriented, then filling speed is improved, but manufacturing precision deteriorates
Solution Approach 1:
The system performs preliminary orientation of capsule casings before the filling process. The carriages are configured to receive and hold capsule casings in the correct orientation, and the vacuum ports are positioned to engage with properly oriented casings. This preliminary action ensures that all capsules are correctly positioned before filling begins, maintaining both high precision and productivity without requiring reorientation during the filling process.
