Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional weighing and packaging systems face difficulties in supplying objects from a weighing machine with a fixed discharge outlet to package bags being conveyed at high speed, as the fixed position of the discharge outlet makes it challenging to align with the moving package bags.
Innovation Solution
A packaging apparatus comprising a link apparatus with funnel-shaped chutes and a conveyor system that rotates to align the discharge outlets with the moving package bags, allowing objects to be discharged from the weighing machine into the chutes and subsequently into the package bags, ensuring efficient supply at high speeds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If package bags are conveyed at high speed, then productivity is improved, but it becomes difficult to align the fixed discharge outlet with the moving package bags
Solution Approach 1:
The patent applies the dynamics principle by making the discharge outlet movable rather than fixed. The discharge outlet is mounted on a movable mechanism that can adjust its position to follow the moving package bags, enabling synchronization between the high-speed conveyance and the discharge operation. This resolves the contradiction by allowing the discharge outlet to adapt dynamically to the changing position of package bags during conveyance.
Solution Approach 2:
The patent introduces an intermediary mechanism between the fixed discharge outlet and the moving package bags. This intermediary is a movable positioning mechanism that acts as a bridge, transferring objects from the stationary weighing machine to the moving package bags while maintaining proper alignment during high-speed conveyance.
2Device complexity
If a fixed discharge outlet is used, then device complexity is reduced, but it cannot supply objects to rapidly moving package bags
Solution Approach 1:
The patent transforms the static discharge outlet into a dynamic component with movable positioning capability. This allows the discharge outlet to maintain proper alignment with rapidly moving package bags while supplying objects, thereby enhancing productivity without requiring an entirely complex reconfiguration of the discharge system.
Solution Approach 2:
The patent segments the discharge outlet into separable components that can move independently. By dividing the discharge outlet structure into modular segments mounted on movable mechanisms, the system achieves the ability to track and supply to high-speed package bags while keeping each segment relatively simple in design.
