Automated Unloading Chute Alignment Using Image Sensors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for transferring agricultural materials from carts or wagons to trucks often result in unwanted collisions due to improper alignment, leading to downtime during harvest seasons, as they lack effective automated unloading mechanisms.
Innovation Solution
A system that includes an unloading chute on a material-transferring vehicle, a location-determining receiver, and an image sensor to estimate position data and lateral separation distance, guiding the vehicle to maintain a minimum target separation from the material-receiving vehicle using an electronic data processing system, ensuring safe and efficient transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automated unloading mechanisms are implemented, then collision prevention and alignment accuracy improve, but device complexity increases
Solution Approach 1:
The patent replaces manual mechanical alignment operations with automated optical sensing and electronic control systems. Image sensors capture visual data of the receiving vehicle, and a processor automatically calculates and adjusts the cart's position, eliminating the need for manual alignment while reducing collision risk.
Solution Approach 2:
The system uses image sensors to create a visual copy or representation of the receiving vehicle and surrounding environment. This optical copy is then processed to determine precise positioning and alignment, allowing the system to navigate and unload without direct mechanical contact or human intervention.
2Device complexity
If manual alignment is used, then device complexity remains low, but collision risk and downtime increase
Solution Approach 1:
The system enables the cart to automatically perform its own alignment and positioning operations without requiring external assistance or complex manual procedures. The onboard image sensors and processor allow the vehicle to self-correct its position and maintain proper alignment throughout the unloading process.
Solution Approach 2:
The system continuously monitors the relative position between the cart and receiving vehicle using image sensors, processes this visual feedback information, and automatically adjusts the cart's position accordingly. This closed-loop control ensures maintained alignment and prevents collisions without requiring complex pre-programming.
3Manufacturing precision
If precise alignment systems are implemented, then unloading accuracy improves, but measurement and detection difficulty increases
Solution Approach 1:
The patent replaces complex mechanical measurement devices with optical image sensing technology. Standard cameras or image sensors capture visual information about the receiving vehicle's position and dimensions, which is then processed computationally to determine precise alignment, simplifying the measurement process while maintaining high accuracy.
Solution Approach 2:
The system transitions from direct linear measurement to two-dimensional visual field analysis. By capturing the receiving vehicle in an image and analyzing its position, size, and orientation in the visual field, the system can calculate precise alignment parameters without requiring direct mechanical contact or complex distance measurement devices.

AI summary
A system (11) for managing the transfer of agricultural material from a material-transferring vehicle to a material-receiving vehicle. An unloading chute is adapted to transfer material from a first storage container of the material-transferring vehicle to a material-receiving vehicle alongside the material-transferring vehicle. A location-determining; receiver (20) is adapted to estimate position data for guiding the material-transferring vehicle. An image sensor (18) is mounted on the material-transferring vehicle or the first storage container for estimating a lateral separation distance between the first storage container and the material-receiving vehicle for receiving the material. An electronic data processing system (10) guides the material-transferring vehicle based on the estimated position data and the estimated lateral separation distance, to maintain a generally constant target lateral separation distance between the material-transferring vehicle and the material-receiving vehicle during the transfer of the material.
