Article Conveyance Alignment Detection for Reliable Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing article conveyance systems face difficulties in reliably delivering articles between stations and carriages due to unfavorable positional relationships, which can lead to article loss during delivery.
Innovation Solution
An article conveyance system with detection and control mechanisms to ensure that article delivery only occurs when the relative position between a station and a carriage is within a deliverable range, using detection sections to assess positional alignment and control sections to permit or restrict delivery based on this alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the carriage stops at the station based on arrival detection, then the conveyance automation is improved, but the article delivery reliability deteriorates due to unfavorable positional relationships
Solution Approach 1:
The detection section performs preliminary detection of the relative position between the carriage and station before the delivery action is executed. The control section uses this advance information to determine whether to permit delivery, preventing delivery issues before they occur by ensuring proper positional alignment is achieved first.
2Productivity
If the carriage stops at the station based on arrival detection, then the conveyance efficiency is improved, but the article loss risk increases due to positional misalignment
Solution Approach 1:
The detection section provides feedback information about the relative position between the carriage and station to the control section. This feedback loop enables the control section to make informed decisions about whether to permit delivery, ensuring that delivery only occurs when positional conditions are satisfied, thereby preventing article loss while maintaining efficient conveyance.
3Speed
If delivery is permitted whenever the carriage arrives at the station, then the operation speed is improved, but the delivery safety deteriorates due to unfavorable positional relationships
Solution Approach 1:
The detection section performs preliminary detection of the relative position between the carriage and station before the delivery action is executed. The control section uses this advance information to determine whether to permit delivery, preventing delivery issues before they occur by ensuring proper positional alignment is achieved first.
Solution Approach 2:
The detection section and control section act as intermediaries between the carriage arrival and the article delivery process. This intermediary mechanism ensures that delivery only occurs when proper positional alignment is confirmed, mediating between the need for quick delivery and the requirement for safe delivery conditions.

AI summary
An article conveyance system includes a station, a carriage, a detection section, and a control section. The station is configured to deliver an article. The carriage is configured to automatically convey the article into or out of the station and travel. The detection section is provided on at least one of the station and the carriage, and detects a relative position between the station and the carriage. When the detection section detects that the relative position is within a first range where the article can be delivered between the station and the carriage, the control section permits delivery of the article between the station and the carriage. When the detection section does not detect that the relative position is within the first range, the control section restricts the delivery of the article between the station and the carriage.
