Automated Parcel Loading Device with Parallel Conveyor Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for loading and unloading shipping containers are not time and space efficient, as they often require multiple cycles and cannot simultaneously load or unload a full row of parcels, especially when dealing with varying sizes and shapes, and often necessitate pre-sorting and reprogramming.
Innovation Solution
An autonomous loading/unloading device equipped with multiple conveyors, a pusher system, and a sensing system that allows for simultaneous loading/unloading of full rows by pre-organizing parcels, extending conveyors to cover the full width of the container, and using adjustable components to align and stack parcels efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing loading/unloading devices are used, then parcels can be loaded and unloaded, but multiple cycles are required and time efficiency is reduced
Solution Approach 1:
The device divides the container width into multiple segments, with each conveyor unit responsible for a specific segment. Multiple conveyors operate simultaneously to load/unload different portions of the container in parallel, reducing the total number of cycles needed compared to sequential single-conveyor operations.
Solution Approach 2:
The invention transitions from single-row sequential loading to multi-row parallel loading by utilizing the width dimension of the container. Multiple conveyors are arranged side-by-side to cover different width segments, enabling simultaneous operation across multiple rows and significantly reducing cycle time.
2Area of stationary object
If existing devices load/unload parcels, then cargo space is utilized, but dead space around machine edges reduces space efficiency
Solution Approach 1:
The modular conveyor units are designed to be universally applicable across different container widths. By adjusting the number and arrangement of conveyor units, the system can adapt to various container sizes and maximize the use of available cargo space without leaving significant dead zones, unlike fixed-position machines.
Solution Approach 2:
The device employs movable and adjustable conveyor components that can dynamically reposition to optimize space utilization. The conveyors can extend to cover the full width of the container and adjust their positions to minimize dead space around edges, thereby improving both space efficiency and productivity.
3Adaptability or versatility
If parcels of varying sizes are loaded, then diverse cargo can be accommodated, but pre-sorting and reprogramming are required
Solution Approach 1:
The sensing system automatically detects parcel dimensions and characteristics, and the control system autonomously adjusts conveyor positions and loading patterns without requiring manual reprogramming. This self-adjusting capability allows the device to handle parcels of varying sizes efficiently, eliminating the need for complex pre-sorting operations and reducing device complexity.
4Productivity
If multiple conveyors are used to improve efficiency, then full rows can be loaded simultaneously, but device complexity increases
Solution Approach 1:
The device is segmented into multiple independent but coordinated conveyor units, each capable of operating autonomously. This segmentation allows simultaneous loading of multiple rows while maintaining manageable complexity through modular design, where each unit follows the same control logic and can be independently maintained or replaced.
