Image-Guided Article Loading to Prevent Placement Collisions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing article loading facilities face issues where target articles are placed incorrectly, potentially colliding with already loaded articles, leading to damage, due to inaccuracies in positioning and orientation based on arrangement information.
Innovation Solution
An article loading facility equipped with an image capturing device above the support to determine the presence or absence of loaded articles, executing specific loading controls to avoid collisions by adjusting the release height of target articles based on captured image information, ensuring accurate placement according to arrangement information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the target article is placed on the loading surface region based on arrangement information, then the loading efficiency is improved, but the target article or loaded article may be damaged due to collision
Solution Approach 1:
The system performs preliminary detection of the loading surface region using an image capturing device before placing the target article. This preliminary action identifies whether the region is occupied, allowing the control unit to adjust the placement strategy accordingly, thus preventing collision damage while maintaining loading efficiency
Solution Approach 2:
The image capturing device provides real-time feedback about the loading surface region occupancy status. The control unit uses this feedback information to dynamically adjust the loading operation, either proceeding with placement when the region is clear or modifying the action when occupancy is detected, thereby preventing article damage
2Manufacturing precision
If the holding unit releases the target article closer to the loading surface region, then the placement precision is improved, but the risk of collision with loaded articles increases
Solution Approach 1:
The system performs preliminary detection of the loading surface region using an image capturing device before the holding unit releases the target article. This preliminary action provides information about the occupancy status, allowing the control unit to adjust the release timing and position to achieve precise placement without collision
Solution Approach 2:
The control unit dynamically adjusts the release parameters of the holding unit based on real-time image information. When the loading surface region is determined to be clear, the article is released closer to the target position for high precision. When occupancy is detected, the release parameters are modified to prevent collision, thus adapting the placement process to current conditions

AI summary
A control unit executes first loading control if it is determined that a loaded article is not present above a loading surface region based on captured image information, and second loading control if it is determined that it is uncertain whether the loaded article is not present above the loading surface region based on the captured image information. The first loading control causing a holding unit to release a target article when the target article is directly above the loading surface region and the lower surface of the target article is higher than the upper surface of the loading surface region by a first specified distance, and the second loading control causing the holding unit to release the target article when the target article is directly above the loading surface region and the lower surface of the target article is higher, by a second specified distance, than a specified height.
