Automated Alignment Mechanism for Pharmaceutical Blister Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automated pharmaceutical packaging systems face delays and inefficiencies due to the use of common funnels and robotic arms, which slow down the transmission of solid pharmaceutical products into blister package cavities, limiting throughput and increasing costs as demand for faster and more accurate packaging grows with the aging population.
Innovation Solution
An automated alignment mechanism transforms randomly arranged solid pharmaceutical products from a two-dimensional array into a linear transmission system using wedge-shaped members and mechanical guides, allowing direct and rapid transmission into blister package cavities, combined with escapement mechanisms for precise dispensing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a common funnel is used to receive and transmit solid pharmaceutical products from multiple canisters, then the system can handle multiple products through a single pathway, but the transmission time for each product increases due to delays and alignment requirements
Solution Approach 1:
The patent divides the single common funnel into multiple separate funnels, each dedicated to transmitting a specific pharmaceutical product. This segmentation eliminates the need for products to share a common pathway, removing delays associated with switching and alignment between different products in a single funnel.
Solution Approach 2:
The patent transitions from a vertical stacking arrangement with a single common funnel to a horizontal array arrangement with multiple separate funnels. This dimensional change allows each product to have its own dedicated transmission pathway, eliminating the time losses associated with vertical gravity feed and alignment in a single funnel system.
2Measurement precision
If a robotic arm is used to selectively locate dispensing canisters at blister package cavity locations, then the system can accurately place products, but the cumulative transit time for moving each canister is significant
Solution Approach 1:
The patent pre-arranges multiple funnels in a horizontal array with each funnel pre-configured for a specific pharmaceutical product. The funnels are positioned in advance to correspond with blister package cavity locations, eliminating the need for a robotic arm to move canisters during the packaging process. The system is prepared beforehand to enable direct transmission.
Solution Approach 2:
The patent removes the robotic arm component from the system entirely, replacing it with a fixed array of funnels that directly transmit products to their destinations. This extraction eliminates the cumulative transit time associated with robotic arm movement while maintaining placement accuracy through the fixed funnel positions.
3Device complexity
If vertically stacked canisters with gravity feed are used, then the system can simplify the transmission mechanism, but the transmission speed and throughput are limited
Solution Approach 1:
The patent changes from a vertical stacking arrangement to a horizontal array arrangement of funnels. This dimensional change allows for parallel transmission of multiple products simultaneously, dramatically increasing throughput while maintaining the simplicity of gravity-fed mechanisms. Each funnel operates independently in its own horizontal plane.
Solution Approach 2:
The patent combines multiple individual gravity-fed transmission pathways into a single horizontal array system. While each individual funnel remains simple, the combined system achieves high throughput by processing multiple products simultaneously through parallel pathways, merging the simplicity of gravity feed with the productivity of parallel processing.

AI summary
A variety of systems and methods are described which quickly and conveniently provide for the selective transmission of individual solid pharmaceutical products from a common location into individual blister package product cavities. In accordance with the preferred exemplary embodiments, an automated alignment mechanism alters the orientation of solid pharmaceutical products that are initially arranged randomly in a two-dimensional array into one or more linear transmission systems. Each linear transmission system is essentially a one-dimensional stack of solid pharmaceutical products, vitamins or other elements. In accordance with another aspect of the present invention, after the solid pharmaceutical products have been arranged in one or more of the linear transmission systems or vertical stacks, the solid pharmaceutical products are selectively transmitted into individual product package blister cavities or into product package templates having locations corresponding to the blister package cavities.
