Abstract

The invention provides an automatic winder, comprising a gate tensioner (26) capable of enduing the tension on the yarn to be winded on a pony roll (P) after being unwound from a bobbin (12), a tension sensor (3) for detecting the tension of the yarn and mounted on the yarn passage (Y) over the gate tensioner (26). The automatic winder can directly detect the unwinding tension of the bobbin (12),the unwinding tension of the yarn unwinding auxiliary device, the tension endued by the gate tensioner (26), free from the tension variance infection due to the other factors. Thus the automatic winder not only directly detects the generation of the abnormal tension when the abnormal tension generates, but also easily determines the generation cause, thereby preventing the end broke due to abnormal tension or bad pony roll winding shape from generating.

Description

technical field

[0001] The present invention relates to an automatic winder for forming bobbins by winding yarn from bobbins. Background technique

[0002] The automatic winder winds a bobbin produced by a spinning machine or the like to form a package of a predetermined shape. For example, as shown in Japanese Patent Laid-Open No. 10-87175, an automatic bobbin winder is provided with: a tensioner for applying appropriate tension to the unwound yarn of the bobbin; a yarn clearer for checking yarn defects; The connector (wiring device) that connects the end of the wire when the device breaks, and the traverse roller that rotates the bobbin at high speed through frictional contact, etc.

[0003] The automatic winder needs to adjust the winding tension of the tensioner in order to make the bobbin shape uniform. In the past, the winding adjustment is to reduce the tension as the winding diameter increases according to empirical values, so that the winding density of the bobbin...
