Star Distributor for Tablet Press Indentation Filling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for distributing tablet blanks to tablet press dies often leave indentations unfilled, limiting the capacity utilization of the tablet press.
Innovation Solution
A device with a rotating disc having indentations on its circumference, where tablet blanks are accommodated in a form-fitting manner, and an outer blank guide to prevent protrusion, along with ejectors and an acceleration mechanism to ensure each indentation is filled, synchronizing with the tablet press's rotation to align and press blanks into dies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a rotating disc with indentations is used to distribute tablet blanks, then the tablet press capacity can be fully utilized, but the complexity of the distribution device increases
Solution Approach 1:
The distribution disc is segmented into multiple circumferential indentations, each capable of holding a tablet blank. This segmentation allows simultaneous loading of multiple blanks onto the disc, enabling full utilization of the tablet press capacity while maintaining a relatively simple overall structure.
Solution Approach 2:
The distribution disc acts as an intermediary device between the tablet blank supply and the tablet press dies. It receives blanks, holds them in organized positions, and delivers them to the dies in sequence, simplifying the coordination between supply and pressing operations.
2Productivity
If ejectors are used to press tablet blanks into indentations, then all indentations can be filled, but the device complexity increases
Solution Approach 1:
The ejectors operate periodically, pressing tablet blanks into the indentations at specific intervals during the disc rotation. This periodic action ensures that all indentations are filled at the appropriate times without requiring continuous complex mechanisms.
Solution Approach 2:
The ejectors are positioned to automatically press blanks into the indentations as the disc rotates, utilizing the natural rotation and positioning of the disc to facilitate the loading process without requiring additional complex control mechanisms.
