Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for setting up tamping style capsule filling equipment are inefficient due to reliance on trial and error, particularly in configuring dosing disc thickness, powder level, and tamping pin settings, leading to time and material losses.
Innovation Solution
A tamping simulator with a powder cylinder, dosing receptacle, and tamping pin system that includes a compression scale and penetration scale to replicate and predict settings, allowing for precise adjustment of tamping pin settings, dosing disc thickness, and powder level, using a rotatable dosing disc with thickness adjustment devices to accommodate different dosages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If trial and error methods are used to configure dosing disc thickness, powder level, and tamping pin settings, then the filling equipment can be set up, but time and material are lost due to inefficiencies in production
Solution Approach 1:
The patent applies preliminary action by using a tamping simulator to determine optimal tamping pin settings, dosing disc thickness, and powder level configurations before actual production begins. The simulator allows operators to pre-test and establish correct settings using a scaled model that replicates the behavior of the full-scale filling equipment, thereby eliminating the need for time-consuming trial and error during production setup.
2Productivity
If trial and error methods are used to configure dosing disc thickness, powder level, and tamping pin settings, then the filling equipment can be set up, but material loss occurs due to inefficiencies in production
Solution Approach 1:
The simulator enables preliminary determination of correct dosing disc thickness and powder level settings before production starts. By testing configurations in advance on the simulator, operators can identify the optimal settings that minimize material waste, avoiding the material loss that occurs during trial and error adjustments on the actual filling equipment.
3Measurement precision
If a slug tester is used to determine filling equipment settings, then dosing disc thickness and slug quality can be identified, but the measurements do not translate well to settings for configuring the filling equipment including tamping pin settings
Solution Approach 1:
The patent applies the copying principle by creating a tamping simulator that is a scaled replica of the actual filling equipment's tamping mechanism. The simulator includes a dosing disc, powder receptacle, and tamping pin that replicate the geometry and mechanics of the production machine. This physical copy allows direct translation of settings because the simulator is designed to be geometrically similar to the actual equipment, enabling operators to determine settings on the simulator and directly apply them to the full-scale machine without complex conversions.
Solution Approach 2:
The simulator acts as an intermediary device between the slug tester measurements and the actual filling equipment settings. While the slug tester provides useful data on slug quality, the simulator serves as a middle ground that allows operators to experiment with and optimize all settings (including tamping pin parameters) in a controlled environment before applying them to the production machine, bridging the gap between measurement and practical configuration.
4Manufacturing precision
If high operator expertise is required to configure dosing disc thickness, powder level, and tamping pin settings, then precise settings can be achieved, but the complexity of operation increases
Solution Approach 1:
The simulator enables operators to independently determine optimal settings through direct experimentation on the scaled model without requiring extensive expertise or external assistance. The self-contained nature of the simulator, with its visible components and direct measurement capabilities, allows operators to learn and adjust settings autonomously, reducing the need for highly skilled personnel while maintaining precision.
Solution Approach 2:
By providing a simplified physical copy of the filling equipment's tamping mechanism, the simulator makes the configuration process more accessible. The scaled model reveals the relationships between dosing disc thickness, powder level, and tamping pin settings in a more intuitive and manageable way than the complex full-scale equipment, allowing operators with varying levels of expertise to achieve precise settings through direct observation and adjustment.
