Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single conveyor belt is used for stacking workpieces, then the press equipment can operate continuously, but the stacking accuracy deteriorates due to the accumulation technique being prone to errors
Solution Approach 1:
The invention divides the stacking system into multiple independent conveyor belts (first conveyor belt and second conveyor belt) that can transport different materials separately. This segmentation allows each conveyor to maintain its own positioning accuracy while feeding materials to the stacking position, thereby resolving the accuracy deterioration caused by single-conveyor accumulation techniques.
Solution Approach 2:
The invention introduces a positioning mechanism that acts as an intermediary between the conveyor belts and the stacking position. This positioning mechanism ensures precise alignment of workpieces from different conveyors before stacking, maintaining high stacking accuracy while enabling continuous operation from multiple material sources.
2Productivity
If the stacking technique is used to accumulate workpieces, then productivity is maintained, but the accuracy deteriorates due to the top-layer plate sliding during stacking
Solution Approach 1:
The invention implements preliminary positioning actions before the actual stacking occurs. The positioning mechanism pre-aligns the workpieces on the conveyor belts and at the stacking position, ensuring that when stacking happens, there is no sliding or misalignment. This preliminary action maintains both high stacking speed and high positioning accuracy.
3Adaptability or versatility
If multiple materials from different conveyors are supplied, then versatility is improved, but the system complexity increases due to coordination requirements
Solution Approach 1:
The invention designs the stacking apparatus with universal positioning and stacking mechanisms that can handle different types of materials from multiple conveyor belts. The positioning mechanism and stacking position are designed to accommodate various material dimensions and shapes, providing versatility while maintaining a relatively simple system structure through standardized interfaces.
