Spinning-winding apparatus and spinning-in method therein

Abstract

The invention provides a spinning-winding apparatus and spinning-in method and a spinning-in method therein which may reduce the amount of waste yarns. In the spinning-winding apparatus with a drawing-out device (10), a godet roller group (20), a first winding device (30) and a second winding device (40), the first winding device (30) and the second winding device (40) are provided with first bobbin support shafts (31, 41) on which bobbins (31B, 41B) for spinning in are mounted, and second bobbin support shafts (32, 42) on which bobbins (32B, 42B) for switching silk yarns from the bobbins (31B, 41B) of the first bobbin support shafts (31, 41) are mounted, respectively; the first winding device (30) is at a spinning-in rotating speed (L) while spinning in to the bobbin (31B) of the first bobbin support shaft (31), and at a production rotating speed (H) after completing spinning-in of the bobbin (31B); and the second winding device (40) is at the production rotating speed (H) while spinning in to the bobbin of the first bobbin support shaft (41).

Description

technical field [0001] The present invention relates to the technology of spinning winding equipment and spinning-in method in spinning winding equipment. More specifically, it relates to a spinning winding facility capable of reducing the amount of waste yarn and a spinning method in the spinning winding facility. Background technique [0002] Conventionally, we have known spinning and winding equipment that bundles single fibers spun from a spinning device to form a plurality of yarns, draws and tempers each yarn separately, and winds them onto a bobbin. [0003] Among such spinning and winding facilities, there is one that increases the number of produced yarns by providing one spinning device with a plurality of winding devices, thereby improving the production efficiency of the yarns (see, for example, Patent Document 1). [0004] And, also have a plurality of bobbin support shafts in the winding device, when the silk thread on the bobbin of one bobbin support shaft be...

AI Technical Summary

Problems solved by technology

[0006] Especially in the case where a plurality of winding devices are provided in one spinning device, since it is necessary to make the rotation speed of the bobbins in all the winding devices equal to the rotation speed at the time of spinning-in, it is necessary to spin-in each bobbin. , so all the silk thread (chaotic thread) wound on the bobbin at the time of threading has to be discarded, so there is a problem of a large amount of waste thread
