Lifting Arrangement for Automated Pharmaceutical Dosing Unit Feeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current packaging machines require manual operations for feeding and maintaining the dosing unit, which disrupts sterility, increases operational costs, and poses health risks due to direct contact with pharmaceutical powders, necessitating the development of a system that automates the feeding process without manual intervention and maintains sterility.
Innovation Solution
An apparatus with a lifting arrangement and airtight containment element that allows for the automatic transfer and connection of product containers to the dosing unit, enabling continuous operation without manual operator contact, using a conveying arrangement that forms an intermediate product store tank and includes a ventilation system for maintaining sterility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operations are used for feeding and maintaining the dosing unit, then operators can perform the required tasks, but production is interrupted and sterility is compromised
Solution Approach 1:
The system enables self-service operation where the dosing unit automatically receives product from the container through the lifting arrangement and conveying system, eliminating the need for manual intervention during the feeding process while maintaining production continuity
Solution Approach 2:
A conveying arrangement acts as an intermediary between the container and dosing unit, automatically transferring product through a controlled interface that maintains sterility while enabling continuous operation without manual intervention
2Ease of operation
If operators directly handle product containers and connecting pipes, then assembly and feeding operations can be performed, but contamination risk increases
Solution Approach 1:
The system extracts the product transfer operation from the sterile environment by using a dedicated conveying arrangement that interfaces with the dosing unit through a controlled boundary, allowing operators to handle containers outside the sterile zone while maintaining sterility inside
Solution Approach 2:
The conveying arrangement serves as an intermediary barrier between the non-sterile external environment and the sterile dosing unit, enabling product transfer without direct operator contact with sterile components
3Ease of operation
If the machine is stopped for refilling and maintenance operations, then manual intervention can be performed, but production efficiency decreases
Solution Approach 1:
The lifting arrangement and conveying system enable continuous product transfer to the dosing unit without stopping the packaging machine, maintaining uninterrupted production while automatically performing refilling operations
Solution Approach 2:
The system performs self-service refilling where the conveying arrangement automatically transfers product from the container to the dosing unit without requiring the machine to stop or manual intervention, maintaining continuous production efficiency
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 allows for continuous operation of packaging machines without interrupting production, reduces the risk of contamination and health hazards, and minimizes the need for direct operator contact with sterile components, thereby lowering operational costs and ensuring sterility is maintained.
Implementation Method 1
a lifting arrangement for picking and moving at least a container (200) of product in such a way as to connect said container to said dosing unit
Implementation Method 2
The monodirectional air flow consists of parallel streams of sterile air that move in the same direction substantially at the same speed, in such a way as to create a homogenous air current without turbulence
