Yarn Spindle Doffing Scheduling Across AGV and Overhead Rail Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing automated guided vehicle (AGV) systems for doffing yarn spindle products in winding machines face inefficiencies due to limited operating speed and path constraints, leading to delayed doffing tasks and potential tube bursting, which increases production costs.
Innovation Solution
A doffing scheduling method and apparatus that coordinates the use of AGVs and overhead rail doffing vehicles by determining the target doffing vehicle based on time-related information from winding machines, ensuring timely completion of doffing tasks and preventing tube bursting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If AGV is used for doffing yarn spindle product, then automation is improved, but doffing efficiency deteriorates due to limited operating speed and path
Solution Approach 1:
The patent combines two different types of doffing vehicles (AGV and overhead rail doffing vehicle) into a coordinated system. The scheduling system assigns tasks to both vehicle types based on their respective advantages, allowing the AGV to handle certain doffing operations while the overhead rail doffing vehicle handles others, thereby achieving both automation and high efficiency
Solution Approach 2:
The patent implements dynamic task assignment and scheduling for doffing vehicles. The scheduling system continuously monitors the status, location, and availability of both AGV and overhead rail doffing vehicle, dynamically adjusting task allocation to optimize doffing efficiency while maintaining automation
2Extent of automation
If AGV is used for doffing, then automation is improved, but doffing timeliness deteriorates leading to tube bursting
Solution Approach 1:
The scheduling system implements real-time feedback mechanisms by continuously monitoring the winding machine status, yarn spindle product winding state, and doffing vehicle availability. This feedback enables the system to predict when doffing is needed and dispatch the appropriate vehicle in advance, preventing tube bursting while maintaining automation
Solution Approach 2:
The system performs preliminary assessment and preparation for doffing operations. By monitoring the winding process and predicting when yarn spindle products will be fully wound, the scheduling system can dispatch doffing vehicles in advance to reach the designated position before doffing is required, preventing tube bursting

AI summary
Provided is a doffing scheduling method and apparatus for yarn spindle product, and storage medium, applied in an automatic doffing system, relating to the field of computer technology, and particularly to the field of automation control. The automatic doffing system is connected to an automated guided vehicle, (AGV) and an overhead rail doffing vehicle, the AGV and the overhead rail doffing vehicle being deployed in different vertical spaces within a target workshop. The method includes: determining a target doffing vehicle corresponding to a first winding machine in the target workshop from the AGV and the overhead rail doffing vehicle based on time-related information of doffing the yarn spindle product in all or part of winding machines in the target workshop; scheduling the target doffing vehicle to complete a doffing task of the yarn spindle product in the first winding machine.
