Conveyor Path Alignment Using Reference Positions and Measured Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing conveyor device abnormality detection systems face challenges in accurately determining abnormal locations due to image blur caused by vibrations, especially when using cameras to generate transportation path layouts, which can lead to deviations from the actual layout and reduced recognition accuracy.
Innovation Solution
An information processing device that acquires drawing data with set reference positions and measured data from the transportation path, detects corresponding reference positions, and corrects the path between them by superimposing and interpolating to align the actual layout with the measured data, improving accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a camera is used to generate transportation path layout information during container transportation, then the system can determine abnormal locations without requiring physical guides or rollers, but image blur caused by vibration reduces path recognition accuracy
Solution Approach 1:
The patent applies preliminary action by pre-acquiring drawing data that contains reference positions before the actual transportation occurs. This pre-prepared reference data is then used to correct the path recognized during transportation, compensating for the image blur caused by vibration. The correction process aligns the blurred measured path with the accurate reference path using the pre-established reference positions.
2Reliability
If fixed detecting units such as sensors are mounted around the conveyor device, then fault detection can be performed, but the detection range is limited
Solution Approach 1:
The patent applies self-service by mounting the detecting unit (camera and sensor module) on the container itself rather than fixing it to the conveyor device. This allows the container to perform its own detection during transportation, enabling the system to monitor the entire transportation path without requiring external fixed detecting units, thereby expanding the detection range while maintaining fault detection capability.
3Measurement precision
If guide poles or rollers are used to establish reference positions for path correction, then path accuracy can be improved, but these components cannot be installed on all conveyor types such as belt conveyors
Solution Approach 1:
The patent applies copying by using drawing data that represents the ideal transportation path as a reference model. Instead of requiring physical guides or rollers, the system creates a digital copy of the expected path geometry and uses it to correct the actually measured path. This virtual reference path can be applied to any conveyor type without requiring physical installation of guide components.

AI summary
An information processing device includes a communication unit configured to acquire drawing data in which a plurality of reference positions is set on a transportation path constituted of a transportation device and measured data which is obtained as a result of transportation on the transportation path and which includes a shape of the transportation path. The information processing device further includes a processing unit configured to detect reference positions in the measured data, superimpose the reference positions in the drawing data and the reference positions in the measured data corresponding to the reference positions in the drawing data onto each other, and correct a path between the reference positions in the measured data.
