Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing article transport facilities face challenges in managing article transportation due to erroneous transfers and mismatched operations between transport vehicles and operators, leading to inefficiencies and difficulty in managing the entire transportation process.
Innovation Solution
An article transport facility with a managing device that includes a reader to read identification information and an identifier to confirm the holding state of articles on transport vehicles, ensuring proper transfer operations by satisfying reading and loaded conditions before allowing vehicles to depart from stop positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual transfer operation is performed by operator, then flexibility in article transfer is maintained, but erroneous transfer and operational mismatch occur
Solution Approach 1:
The system implements feedback mechanisms where the reader reads identification information of articles and the identifier detects the holding state of articles on transport vehicles. The managing device uses this feedback information to verify transfer accuracy and control vehicle departure, preventing erroneous transfers while maintaining operational flexibility.
Solution Approach 2:
The patent replaces manual mechanical transfer operations with an automated system comprising a reader, identifier, and managing device. This substitution eliminates human error in transfer operations while maintaining the flexibility to handle various article types through automated identification and verification processes.
2Reliability
If automated transfer operation is implemented, then transfer accuracy is improved, but system complexity increases
Solution Approach 1:
The managing device performs multiple functions including reading identification information, detecting holding states, controlling vehicle departure, and managing transfer operations. By consolidating these functions into a single multi-functional device, the system achieves high transfer accuracy without proportionally increasing overall system complexity.
Solution Approach 2:
The patent introduces intermediary components (reader and identifier) that mediate between the manual transfer operation and the automated control system. These intermediaries simplify the interaction between human operators and automated systems, enabling accurate transfers while reducing the complexity burden on the managing device.
3Reliability
If condition verification is performed before departure, then operational errors are prevented, but transfer time increases
Solution Approach 1:
The system performs reading and identification operations in advance before the actual transfer completion. By conducting verification actions preliminarily, the system ensures operational correctness is established before departure while minimizing the time added to the transfer cycle through efficient sequencing of verification steps.
Solution Approach 2:
The managing device continuously monitors and verifies transfer conditions without interrupting the overall transfer process. The reader and identifier operate continuously to detect when articles are properly loaded, allowing condition verification to proceed in parallel with transfer operations rather than as a sequential bottleneck.

AI summary
An article transport facility includes a work area in which a transfer operation is performed to transfer an article (G) supplied from an article supplier to a transport vehicle (1) and a managing device (5) that manages the transfer operation. A travel path (R) includes a stop position (P) at which the transport vehicle (1) stops to receive the article (G) in the transfer operation. The stop position (P) is adjacent to the work area. The managing device (5) causes the transport vehicle (1) to depart from the stop position (P) in response to a reading completion condition and a loaded condition being satisfied. The reading completion condition is satisfied when identification information of a transport target article (G) is read by a reader (51). The loaded condition is satisfied when an identifier (52) determines that the transport vehicle (1) holds the transport target article (G) based on an identification result.
