Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing capsule feeding devices for liquid packaging lines face issues such as jamming, high energy consumption, and hygiene concerns due to air flow, and risk of jamming at high speeds, particularly in ensuring correct orientation and efficient delivery of capsules to the capping station.
Innovation Solution
A device utilizing a curved guide profile to ensure centrifugal referencing of capsules ejected from a belt, where capsules press against each other and are guided by a curvature to maintain orientation, eliminating the need for artificial motor-driven guidance and reducing jamming risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If air flow is used to convey capsules downstream, then capsules can be moved without mechanical contact, but hygiene requirements may not be met and noise increases
Solution Approach 1:
The patent replaces the pneumatic air flow system with a gravity-based mechanical system. Capsules are conveyed downstream through a chute using gravity and controlled by a curved guide profile, eliminating the need for continuous air flow. This substitution resolves the hygiene and noise issues associated with air flow while maintaining effective capsule conveyance.
2Manufacturing precision
If a funnel-shaped progressive restriction is used downstream of the carpet, then capsule guidance is improved, but stacking risk increases significantly at high speeds
Solution Approach 1:
The patent uses a curved guide profile instead of a funnel-shaped restriction. The curved profile at the downstream end of the carpet gradually guides capsules outward in an arc, allowing them to be directed into the chute without abrupt narrowing. This curved geometry maintains capsule orientation while preventing the stacking and jamming that occurs in funnel configurations at high speeds.
3Productivity
If an oblique rule is used to push capsules through the output zone, then capsule ejection is achieved, but jams occur at high speed or when the rule angle is too low
Solution Approach 1:
The patent eliminates the need for periodic mechanical ejection rules by implementing continuous capsule discharge through the curved guide profile. The gravity-based system and curved geometry enable capsules to be continuously and smoothly directed into the chute without the intermittent action of an ejection rule, preventing jams at high speeds while maintaining effective ejection.
4Reliability
If centrifugal referencing with a curved guide profile is implemented, then capsule orientation is maintained and jamming is prevented, but the chute design becomes more complex
Solution Approach 1:
The curved guide profile integrates smoothly into the chute structure, using a simple arc-shaped geometry to achieve centrifugal referencing. This curved design, while more complex than a straight chute, provides reliable jamming prevention and maintains capsule orientation through its geometric properties, representing an acceptable trade-off for improved reliability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables reliable and economical high-rate feeding of correctly oriented capsules, reducing energy consumption and preventing jamming by leveraging inertia and gravity for capsule guidance, ensuring smooth and efficient delivery to the capping station.
Implementation Method 1
ensure centrifugal referencing of the ejected capsules out of the carpet, thanks to a curved guide profile against which they can be used behind the other
Implementation Method 2
a carpet 4 of elevation with supports 5, for a circulation of capsules 2 up during which the poorly oriented capsules are returned to the reception tray 3
Implementation Method 3
the supports 5 forming for them a lower support surface. Capsules 2 can of course be various shapes with each treatment cycle. The elevation by carpet 4 allows the 2 poorly oriented capsules to fall back into the reception tray 3
