Container Purge Nozzle Alignment for Teaching-Free Gas Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional storage devices require time-consuming and labor-intensive teaching processes to position containers correctly for purge gas supply, especially when integrating purge devices into conveyance systems with overhead transport vehicles.
Innovation Solution
A purge device with a base and positioning pins that securely attach a nozzle to the container, allowing for precise positioning and eliminating the need for repeated teaching, even when replacing the nozzle unit, by using a gas introduction portion integrated into the main body and an elastic or rotary arm mechanism for easy installation and adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a purge device is installed in a conveyance system with an overhead transport vehicle, then purge gas can be supplied to the container, but teaching the overhead transport vehicle is required so that the container is positioned correctly and the supply nozzle is securely connected
Solution Approach 1:
The supply nozzle is equipped with a positioning mechanism that automatically aligns and connects to the container's gas inlet based on teaching information about the container's position. The system uses the container's own position data to guide the nozzle's movement and connection, eliminating the need for separate teaching of the overhead transport vehicle.
Solution Approach 2:
The patent replaces complex mechanical teaching and positioning systems with an information-based approach. By using teaching information about container positions and implementing automated positioning control, the system substitutes manual or mechanical alignment procedures with intelligent, information-driven positioning.
2Ease of manufacture
If the supply nozzle is fixed to the storage rack, then the structure is simple, but the nozzle cannot be easily replaced or adjusted
Solution Approach 1:
The supply nozzle is divided into a modular structure where the nozzle body can be separated from the mounting base. This segmentation allows the nozzle to be easily removed and replaced while keeping the mounting structure intact, facilitating maintenance and adjustments without complex disassembly.
3Ease of operation
If the container position is not precisely controlled, then the system is simpler to operate, but the supply nozzle cannot be securely connected to the gas inlet
Solution Approach 1:
The patent replaces complex mechanical positioning systems with an information-based positioning approach. By using teaching information about container positions and implementing automated control, the system achieves precise nozzle-to-gasinlet alignment without requiring complex mechanical adjustment mechanisms, maintaining operational simplicity while ensuring connection reliability.
