Rotary Drum Pill Packaging With Negative Pressure Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pill packaging machines face challenges in accurately filling containers with pills, as they often require operator intervention to correct missing pills and cannot efficiently handle broken or defective pills, leading to inefficiencies and waste.
Innovation Solution
An automated packaging apparatus featuring a rotatable cylindrical drum with pill apertures, utilizing negative pressure to retain pills and ejection devices to selectively remove broken or defective pills, ensuring accurate filling and minimizing operator intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If conventional rotary slats are used to capture and deliver pills to bottles, then automated filling is achieved, but operator intervention is still required to correct missing pills and ensure accurate counts
Solution Approach 1:
The patent implements feedback mechanisms through sensors that detect the presence or absence of pills in each receptacle as the rotary drum rotates. When a missing pill is detected, the system automatically adjusts by diverting an additional pill into the corresponding bottle, ensuring accurate counts without operator intervention.
Solution Approach 2:
The system performs self-correction by automatically detecting missing pills and diverting replacement pills from the supply stream. This self-service capability eliminates the need for manual intervention while maintaining reliable pill counts in each container.
2Productivity
If conventional pill capturing devices are used, then mass production is enabled, but broken or defective pills cannot be efficiently handled, leading to waste and inefficiency
Solution Approach 1:
The patent implements preliminary inspection of pills before they are dispensed into containers. Optical sensors or imaging systems detect defective or broken pills in advance, allowing the system to divert only sound pills into containers while routing defective pills to a separate rejection stream, preventing waste during the filling process.
3Reliability
If manual operator intervention is used to ensure accurate pill counting, then sterility requirements are maintained, but labor costs increase and accuracy cannot be consistently guaranteed
Solution Approach 1:
The patent replaces manual mechanical intervention with automated sensing and control systems. Sensors detect pill presence, and automated mechanisms divert replacement pills or adjust dispensing in real-time, eliminating the need for operators while maintaining or improving counting accuracy and sterility.
4Device complexity
If conventional rotary slats with fixed configurations are used, then simple device structure is maintained, but flexibility to handle different filling requirements is limited
Solution Approach 1:
The patent implements dynamic, adjustable configurations for the rotary drum and receptacles. The system can modify receptacle positioning, rotation speed, and pill diversion timing to accommodate different pill types, container sizes, and filling rates, providing versatility without excessive complexity.
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 apparatus achieves high-speed, accurate pill counting and isolation of defective pills, reducing waste and labor costs while maintaining sterility and quality control.
Implementation Method 1
A negative pressure system is operably engaged with the radially inward portion of the at least one rotary drum and is configured to be in fluid communication with the pill apertures thereof. The negative pressure system is configured to apply a negative pressure to the pill apertures so as to retain the pills therein
Data Source
AI summary
A packaging apparatus and method for depositing pills into a series of containers is provided. A cylindrical rotary slat is rotatable about a first axis and comprises radially inward and outward portions, the radially outward portion defining pill apertures for receiving pills therein at a first angular position. A negative pressure system is configured to apply a negative pressure to the pill apertures to retain the pills therein. Two ejection devices are in communication with the pill apertures at a second angular position and a third angular position of the rotary slat to eject the respective pills outwardly from the pill apertures. A plurality of collection mechanisms is disposed adjacent to the radially outward portion about the second and third angular positions, and is configured to collect the pills ejected from the pill apertures and to direct the pills toward the respective series of containers for deposition therein.
