Bagging Machine Vibration for Humid Granulate Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current packing machines for materials like sand, gravel, clay, and mortar are costly, ergonomically incorrect, time-consuming, and inefficient, especially when dealing with humid products that stick to container walls due to their viscosity and adherence properties, leading to flow obstruction.
Innovation Solution
A machine with a carrying shovel and wheels for direct deposition into a silo with a slope greater than 54°, equipped with a vibrator to prevent sticking, an oscillating tray, and a scale for precise volume or weight regulation, along with a pedal-activated vibrating system and ergonomic design for efficient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a slope lower than 54° is used in the container, then the structure is simpler and easier to manufacture, but the material sticks to the walls and forms caves, obstructing flow
Solution Approach 1:
The patent applies a vibrating mechanism to the container walls to prevent material from sticking and forming caves. The vibration disrupts the adhesion between humid material and the container surface, ensuring continuous flow even with simpler container designs.
Solution Approach 2:
The patent changes the surface characteristics of the container through vibration, effectively modifying the friction and adhesion parameters between the material and container wall, allowing material to flow smoothly without requiring complex inclined structures.
2Extent of automation
If traditional packing machines are used, then packing can be automated, but the machines are costly, occupy large spaces, and require belt conveyors
Solution Approach 1:
The patent combines multiple functions (material receiving, vibration prevention, flow control, and packing) into a single integrated device. The container serves multiple purposes: it receives material, prevents sticking through vibration, and controls flow to the packing area, eliminating the need for separate belt conveyors and complex feeding systems.
Solution Approach 2:
The container is designed as a multi-functional element that performs material reception, vibration-based flow control, and direct delivery to the packing mechanism, replacing multiple specialized components with a single versatile device.
3Manufacturing precision
If valve systems are used for packing, then precise dosing can be achieved, but the endless worm wears quickly due to abrasion from humid products
Solution Approach 1:
The patent removes the problematic valve system with the endless worm from the design. Instead, it uses a vibration-based flow control mechanism that achieves precise dosing without the abrasive contact that causes wear in traditional valve systems.
Solution Approach 2:
The patent replaces the mechanical valve system with a vibration-based control mechanism, substituting direct mechanical contact and abrasion with a non-contact or minimal-contact vibration field for flow regulation.
4Ease of manufacture
If manual packing with shovels is used, then equipment cost is low, but the procedure is costly, stressful, ergonomically incorrect, and time-taking
Solution Approach 1:
The device enables semi-automatic operation where the system itself performs the flow control and dosing functions through vibration, reducing the need for manual intervention while maintaining equipment simplicity. The operator only needs to monitor and adjust parameters, not perform the physically demanding shoveling work.
