Chemical fiber filament doffing method, system and automatic doffing equipment based on twin model

Abstract

The present invention proposes a chemical fiber filament doffing method, including: obtaining the attribute parameters of the winding production line to construct a digital twin model of the winding production line; obtaining the real-time parameters of the current chemical fiber filament production of the winding production line to construct the The equivalent mapping between the digital twin model and the winding production line; the prediction parameters of the winding production line at a future moment are obtained through the digital twin model, and the doffing scheme is generated through the digital twin model according to the prediction parameters; when reaching the future At time, the winding production line is controlled by the equivalent mapping to perform the doffing operation with the doffing scheme. The invention also proposes a chemical fiber filament doffing system and an automatic doffing device.

Description

technical field [0001] The invention relates to the technical field of chemical fiber production, in particular to a chemical fiber filament doffing system and method. Background technique [0002] The chemical fiber filament package and doffing operation is a typical labor-intensive operation scene. The labor intensity of personnel is high, the working environment is harsh, and the production is continuous for 24 hours. The original manual operation mode has been difficult to meet the needs of enterprise development. Many leading companies are starting to use automated equipment to replace manual work to complete this operation. [0003] At present, most of the leading chemical fiber production enterprises in China have adopted the automatic doffing system to replace the traditional manual operation. [0004] In the Chinese invention patent "Automatic Spindle Conveying System and Spindle Automatic Conveying Method" (application number: CN102431849A), a method for chemical ...

Problems solved by technology

[0005] At present, the chemical fiber filament package is formed, and the winding machine on a production line can produce different types and specifications of various products at the same time. The time from sending out the full volume signal to the occurrence of tube burst) is not the same. At present, the control and scheduling of doffing operations in the chemical fiber industry are all controlled by PLC programs, using queuing theory and the principle of priority calls. The doffing can be done according to the order of the call, and multiple factors such as the position of the doffing and the bursting time cannot be considered comprehensively. It often requires manual participation in the processing, and even the waste of the bursting tube occurs. The existing control and scheduling method can no longer meet the requirements. high quality production requirements
