Spinning-in device and spinning-in method of doffing trolley

Abstract

The invention provides a spinning-in device and a spinning-in method for a doffing trolley. The spinning-in device comprises a doffing trolley rack, a yarn grabbing mechanism, a groove drum, a yarn cleaner, a bobbin yarn small suction nozzle, a bobbin yarn large suction nozzle and a control system, the yarn grabbing mechanism comprises a yarn grabbing cylinder, a yarn grabbing pushing cylinder andyarn grabbing scissors, the yarn grabbing mechanism is characterized in that a telescopic arm of the yarn grabbing air cylinder is formed by inserting a telescopic pipe and a telescopic rod, yarn grabbing scissors are arranged at one end of the telescopic rod, a pushing component of the yarn grabbing pushing air cylinder is connected with the middle of the telescopic pipe of the yarn grabbing aircylinder, and the cone yarn large suction nozzle is in an L shape and participates in doffing. According to the spinning-in method, doffing can be automatically completed when cone yarn exists on thegroove drum, doffing can also be automatically completed when no cone yarn exists on the groove drum, the working efficiency can be improved, and the labor intensity of operators is relieved.

Description

technical field [0001] The invention belongs to the technical field of textile machinery manufacturing, and relates to an improvement of a spinning method for a doffing trolley on a bobbin winder, in particular to a spinning device and a spinning method for a doffing trolley. Background technique [0002] The doffing trolley is a kind of doffing equipment equipped on the automatic winding machine, and it is a necessary configuration on the fine-link automatic winding machine and the large yarn warehouse type automatic winding machine. The doffing trolley replaces manual doffing and unwinding with automatic equipment, which improves the automation level of the automatic winding machine as a whole. Its purpose is to reduce the labor intensity of the car operator and realize the automation of doffing. [0003] When the single spindle sends out a full bobbin signal, that is, the bobbin reaches the length or weight setting value, the doffing trolley removes the full bobbin from ...

AI Technical Summary

Problems solved by technology

[0004] In the existing doffing trolley, there must be a bobbin on the trough to complete the doffing. When the doffing fails for the first time or the whole car changes the yarn variety, since there is no bobbin on the trough, the yarn grabbing cylinder The entire doffing action cannot be completed due to the inability to grab the yarn end

At this time, the operator is required to perform manual operation, which increases the labor intensity of the operator and reduces the production efficiency.
