Conveying Device Controller for Collision-Free Object Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conveying devices face difficulties in efficiently and safely removing objects from a palette at high speeds, particularly when objects are randomly stacked or of varying sizes and shapes, leading to potential collisions and operational inefficiencies.
Innovation Solution
A conveying device equipped with a controller that determines the moving direction of a holder based on the overlapping widths between objects in different directions, using information from detectors to calculate movement amounts and avoid obstacles, allowing for precise and efficient object removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If objects are removed from a palette at high speed, then productivity is improved, but the risk of collision between objects increases
Solution Approach 1:
The controller performs preliminary analysis of object positions and overlapping widths before initiating the removal action. By calculating the optimal moving direction in advance based on detector information, the system ensures collision-free high-speed removal without requiring slow, cautious movement during the actual extraction
Solution Approach 2:
The system uses detectors to continuously monitor object positions and provides feedback to the controller. The controller adjusts the moving direction and speed based on real-time overlapping width measurements, enabling high-speed operation while maintaining collision avoidance through closed-loop control
2Device complexity
If a simple removal method is used, then device complexity is reduced, but the ability to handle randomly stacked objects of varying sizes and shapes deteriorates
Solution Approach 1:
The system uses detectors to automatically acquire information about object positions, sizes, and arrangements. The controller autonomously calculates optimal removal paths based on overlapping widths without requiring complex manual programming or intervention, enabling the system to adapt to random stacking configurations while maintaining relatively simple device architecture
Solution Approach 2:
The controller dynamically adjusts movement parameters (direction, speed, position) based on detected object characteristics. By changing these parameters in real-time according to overlapping widths and object configurations, the system achieves high adaptability to various stacking patterns without requiring a complex mechanical structure

AI summary
According to one embodiment, a conveying device includes a controller that is configured to determine a moving direction of a holder holding a first object based on a state of overlapping between the first object and a second object viewed in a conveying direction of the first object in a case where the second object is positioned in the conveying direction of the first object with respect to the first object.
