Curved Extracting Surface Tensions Foil for Blister Deblistering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing deblistering machines fail to tension the push-through foil effectively, leading to pills being left behind in the blister pack, unstable placement of blister packs, and contamination due to pills dropping onto inaccessible components.
Innovation Solution
A device with a concave, at least partially curved extracting surface that tensions the push-through foil and includes rotatable pressure rollers with adjustable pressure, sweeping means, and adjustable partitions to ensure stable placement and automatic feeding, along with removable cassettes for different blister pack types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the push-through foil is not tensioned during pressing, then the device structure is simple, but pills remain behind in the blister pack
Solution Approach 1:
The extracting surface is designed with a concave curvature that tensions the push-through foil during the pill pressing process. This curved surface configuration creates the necessary tension to ensure complete pill extraction without complicating the overall device structure, as the curvature itself provides the tensioning mechanism.
2Device complexity
If the extracting surface is flat, then the device structure is simple, but the blister pack placement is unstable
Solution Approach 1:
The extracting surface employs a concave curved configuration that provides stable placement for blister packs. The curvature creates a natural nesting effect that secures the blister pack in position, enabling stable placement and facilitating automated feeding operations without requiring additional complex positioning mechanisms.
3Device complexity
If pills drop onto device components, then the collecting means structure is simple, but the components cannot be cleaned effectively
Solution Approach 1:
The device design ensures that pills are directed to drop exclusively into the collecting means, separating the collection function from other device components. This extraction of the pill-dropping function to a dedicated collecting area prevents pills from contaminating inaccessible components, thereby enabling effective cleaning of all components without requiring complex structural changes.
4Device complexity
If the pressure roller moves reciprocally only, then the device structure is simple, but automation possibilities are limited
Solution Approach 1:
The pressure roller is designed to perform both reciprocating movement and rotating movement. This dynamic combination of motion types enhances automation capabilities by enabling the pressure roller to both position itself through reciprocation and apply consistent rolling pressure through rotation, facilitating more sophisticated automated operation sequences.
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 ensures that pills are fully extracted without being left behind, maintains stable blister pack placement for automation, and prevents contamination by ensuring pills drop directly into a collecting means, facilitating efficient and automated operation.
Implementation Method 1
one or more rotatable pressure rollers, wherein each pressure roller is rollable with predetermined rolling pressure over at least a part of the surface of the blister pack during operation for the purpose of pressing the pills out
Implementation Method 2
the at least partially curved extracting surface takes a concave form. This measure ensures that the push-through foil is tensioned when the pills are pressed out
Implementation Method 3
a collecting means placed under the extracting surface for collecting pills which have dropped through the drop openings
