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

Abstract

The invention provides a chemical fiber filament doffing method. The chemical fiber filament doffing method comprises the following steps that attribute parameters of a winding production line are acquired so as to construct a digital twinning model of the winding production line; real-time parameters of current chemical fiber filament production of the winding production line are obtained so as to constructing the equivalent mapping of the digital twinning model and the winding production line; prediction parameters of the winding production line are obtained at a future moment through the digital twinning model, and a doffing solution is generated through the digital twinning model according to the prediction parameters; and when the future moment is reached, the equivalent mapping controls the winding production line to carry out the doffing operation according to the doffing solution. The invention further provides a chemical fiber filament doffing system and automatic doffing equipment.

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 the completion of doffing to the next start of doffing) is different, and 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
