Pasta Dosing Machine Segmented Weighing and Finishing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pasta dosing machines for long-type pasta suffer from uncertainties in dosing accuracy and prolonged process times, leading to inconsistent package quantities and inefficient operation.
Innovation Solution
The pasta dosing machine design reduces the distance between the weighing basket and the conveyor belt by incorporating a horizontally movable blade and a synchronized rotor with radial recesses, along with multiple weight measurers and motors for precise dosing and weighing operations, and a vibrating system for efficient pasta flow, allowing for faster and more accurate dosing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a rotor with radial recess is used to transfer pasta in the roughing channel, then the dosing process can be automated, but the process time increases and dosing accuracy decreases
Solution Approach 1:
The dosing process is divided into two independent channels: a roughing channel for bulk dosing and a finishing channel for precise adjustment. The roughing channel uses a rotor with radial recesses to quickly transfer pasta portions, while the finishing channel performs fine dosing. This segmentation allows each channel to optimize for its specific function, reducing overall process time while maintaining accuracy.
Solution Approach 2:
A weighing basket positioned between the roughing and finishing channels serves as an intermediary element. It receives pasta from the rotor, allows for weight measurement and verification, and then transfers the measured pasta to the finishing channel. This intermediary step enables process optimization by separating the quick transfer function from the precise dosing function.
2Productivity
If the distance between the weighing basket unloading axis and the conveyor belt axis is reduced, then the pasta transfer efficiency improves, but the machine structure becomes more compact and complex
Solution Approach 1:
The weighing basket is positioned such that its unloading axis is vertically aligned near the conveyor belt axis, minimizing horizontal transfer distance. The pasta falls vertically from the basket into the finishing channel, which is positioned directly below or adjacent to the basket. This vertical arrangement in another dimension reduces the transfer path length without requiring complex lateral positioning mechanisms.
