Rotary Feeder Posture Correction for Solid Dosage Singulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional alignment transfer devices face inefficiencies in aligning and transferring solid dosage forms due to improper posture, leading to increased gaps and reduced transfer efficiency.
Innovation Solution
An alignment transfer device with a disk-shaped rotary disk and annular rotary ring, featuring a holding part, guide part, and posture regulating surface to correct improper postures, along with an airflow injection mechanism to ensure proper alignment and transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If solid dosage forms are returned from the second ring to the rotary disk to correct improper posture, then alignment accuracy is improved, but the ratio of gaps between solid dosage forms increases and transfer amount per unit time decreases
Solution Approach 1:
The guide part is positioned to act on solid dosage forms before they are returned to the rotary disk, correcting their posture in advance during the transfer process. This preliminary correction prevents improper postures from causing gap increases later, allowing continuous transfer without requiring returns to the rotary disk.
Solution Approach 2:
The guide part serves as an intermediary component between the second ring and the rotary disk. It intercepts solid dosage forms with improper postures and corrects them before they re-enter the transfer stream, mediating the alignment process without disrupting the continuous transfer flow.
2Manufacturing precision
If a cover is used to return improperly positioned solid dosage forms to the rotary disk, then alignment is improved, but device complexity increases
Solution Approach 1:
The guide part extracts the posture correction function from the complex cover mechanism. Instead of using a cover to return solid dosage forms to the rotary disk, the guide part directly corrects their posture in place, eliminating the need for the cover and simplifying the overall device structure.
Solution Approach 2:
The guide part enables the second ring system to self-correct improper postures of solid dosage forms during transfer, without requiring external intervention from a separate cover mechanism. The system corrects its own alignment issues internally.
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
Efficient alignment and transfer of solid dosage forms are achieved by correcting improper postures using the holding part and guide part, reducing gaps and enhancing transfer efficiency.
Implementation Method 1
a solid dosage form supplied onto the rotary disk receives a centrifugal force and moves to a transfer part
Implementation Method 2
The solid dosage form P to be transferred by the second ring is adsorbed onto the outer peripheral surface of a suction roller
