Position Detection Device for Automatic Transport Target Update
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional article transport facilities face efficiency reduction and increased operator burden due to the need for frequent maintenance operations to update transporting target position information, which is affected by wheel wear and aging, requiring installation of correction sheets at transport target locations, thereby disrupting normal operations.
Innovation Solution
An article transport facility with a control device that executes transport and update controls, including a position detection device for updating target positions, allowing for automatic updates at predetermined intervals without interrupting normal operations by using a separate position updating location, thus maintaining efficiency and reducing operator burden.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If transporting target position information is updated during maintenance operations by installing correction sheets at transport target locations, then position accuracy is improved, but article transport efficiency deteriorates due to operation disruptions
Solution Approach 1:
The patent divides the facility into distinct functional zones: a position updating location separate from transport target locations. The position detection device is installed at the position updating location, allowing position information updates to occur independently without disrupting article transport operations at transport target locations. This spatial segmentation resolves the contradiction by enabling simultaneous position updates and normal transport operations.
2Measurement precision
If maintenance operations are performed frequently to update position information, then position accuracy is maintained, but operator burden increases
Solution Approach 1:
The patent implements automatic position detection and update functionality. The position detection device automatically detects the position of detection target objects and updates transporting target position information without requiring manual operator intervention for each update operation. This automation reduces operator burden while maintaining position accuracy through systematic periodic updates executed by the control device.
3Measurement precision
If the interval between maintenance operations is shortened, then position accuracy is maintained, but operational disruption frequency increases
Solution Approach 1:
The patent enables position information updates to be performed in advance at position updating locations during non-peak operational periods. The control device can update position information proactively before transport operations require it, ensuring position accuracy is maintained without causing operational disruptions. This preliminary action approach allows systematic updates at optimized intervals without affecting transport efficiency.

AI summary
A supporting portion of an article transport device supports a position detection device for detecting the position of a detection target object. A control device executes an update control to update target position information in accordance with an update instruction issued through a manual operation performed by an operator during a maintenance operation performed at an interval longer than a set period, and executes the update control on condition that an elapsed time since issuance of the update instruction has reached an automatic updating time that is a time shorter than the set period.
