Embodiment Construction

[0017] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. figure 1 It is a schematic diagram which shows the winding unit 1 of the automatic winder which concerns on one Embodiment of this invention. The winding unit 1 is equipped with a yarn supplying bobbin 12 inserted upright in the yarn supplying section 11 in the lower part, and a winding device 13 is provided in the upper part, and the winding device 13 is used to wind the yarn unwound from the yarn supplying bobbin 12. Wrap around bobbin P. Winding device 13 has: traverse drum 14 and support 15, wherein, traverse drum 14 utilizes the driving force of motor (not shown) to rotate, and support 15 then makes bobbin P contact with traverse drum 14 with appropriate contact pressure and The bobbin P is rotatably supported in this state. Traversing grooves 16 are formed on the peripheral surface of the traversing drum 14 . In this winding device 13, by r...

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...
