Adjustable Feeding Carriage for Compressor Homogeneity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Compressor machines experience segregation phenomena due to differences in particle properties, leading to non-homogeneous filling and compaction issues, especially in applications requiring specific material proportions, such as pharmaceutical tablet preparation, where existing solutions like fluidizing methods fail to ensure uniformity in compressed articles.
Innovation Solution
A feeding carriage with adjustable geometry based on particulate material properties and proportions, allowing modification of its elements to minimize segregation by determining and applying an optimum geometry through empirical tests or computer simulations using the discrete element method.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a fixed geometry feeding carriage is used, then the device structure is simple, but segregation phenomena occur causing non-homogeneous filling
Solution Approach 1:
The feeding carriage geometry is made adjustable through movable elements (walls, floors, hoppers) that can be repositioned to modify the carriage configuration. This dynamic adjustment allows optimization of particle flow patterns to minimize segregation while maintaining homogeneous filling, resolving the contradiction between composition stability and device complexity.
2Stability of the object's composition
If the feeding carriage geometry is optimized for specific particle properties, then segregation is reduced, but the device loses versatility
Solution Approach 1:
The feeding carriage is designed with multiple adjustable elements (movable walls, floors, hoppers) that can be reconfigured for different particle types and properties. This universal design allows the same device to optimize homogeneity across various applications by adjusting geometry to match specific particle characteristics, resolving the contradiction between composition stability and adaptability.
3Quantity of substance
If particles with different properties are mixed, then material diversity is achieved, but segregation worsens
Solution Approach 1:
The feeding carriage creates different local flow conditions in various zones (hoppers, walls, floors) to accommodate particles with different properties. By optimizing local geometry and flow patterns, the system maintains homogeneous mixing of diverse materials, resolving the contradiction between material composition diversity and composition stability.

AI summary
The invention relates to a feeding carriage for a compressor machine of the type having an upper filling end through which a particulate material which is to be compressed in a mold of the compressor machine is introduced, and a lower discharging end for discharging said particulate material towards said mold. At least some of the elements forming said feeding carriage can move with respect to one another, which thereby allows modifying the geometry of at least one of said lower discharging end, said upper filling end and an intermediate portion of the supply carriage located between both ends. The invention also relates to the use of such a feeding carriage comprising the initial steps of determining optimum carriage geometry for a particulate material which is to be compressed and applying said optimum carriage geometry to the feeding carriage.
