Problems solved by technology

Therefore, when the tubular member is arranged near the exhaust port, the tubular member becomes an obstacle, and the exhaust port cannot be brought close to the package.
Therefore, the yarn cannot be pulled out without increasing the flow rate of the air flow
[0007] On the other hand, in the case of moving the tubular member away from the exhaust port, the exhaust port can be brought closer to the package, but the air flow from the tubular member will be weakened before reaching the exhaust port.
Therefore, the yarn cannot be pulled out without increasing the flow rate of the air flow

Embodiment Construction

[0041] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0042] Such as figure 1 As shown, an automatic winder (yarn winding machine) 1 has: a plurality of yarn winding units 10 arranged side by side, a doffing device 5 , and a machine control device 90 .

[0043] Each yarn winding unit 10 winds the yarn 20 unwound from the yarn supplying bobbin 21 while traversing on the winding tube 22 supported by the cradle (winding tube support portion) 23 to form a package. 30.

[0044] The doffing device 5 moves to the position of the yarn winding unit 10 when the package 30 in each yarn winding unit 10 becomes fully wound, collects the fully wound package 30 and supplies the yarn 20 not wound. Winding tube 22 (empty bobbin).

[0045] The machine control device 90 has a machine setting unit 91 and a machine display unit 92 . The machine setting unit 91 can perform setting for each yarn winding unit 10 by an operator inputting prede...

Abstract

A yarn guiding-out device is proposed. Slits (28a) are formed in a yarn guiding-out device (28). The yarn guiding-out device (28) blows an airflow through the slits (28a) in a direction in which a yarn end (20a) of a package (30) is guided out from the package (30). The slits (28a) are formed so as to generate the airflow that flows along an outer wall surface (specifically, a curved portion (63) and a flat portion (64)) having no opposing wall surface.

Description

technical field [0001] The present invention relates to a yarn drawing device for drawing a yarn end of a package. Background technique [0002] Conventionally, there is known a yarn drawing-out device which is arranged near the package and draws out the yarn end of the package, for example, for yarn splicing or the like. In Japanese Patent Application Publication No. 4-213563 (Patent Document 1), Japanese Patent Application Publication No. 6-219649 (Patent Document 2), Japanese Patent Application Publication No. 2000-177933 (Patent Document 3) and Japanese Patent Application Publication No. 2000-72334 Such a yarn drawing device is disclosed in the gazette (Patent Document 4). [0003] The yarn drawing devices (suction nozzle, flat nozzle) of Patent Document 1 and Patent Document 2 are fixed near the package. Such a yarn drawing-out device can draw out the yarn end of the package by generating a flow of suction air. In addition, Patent Document 1 and Patent Document 2 do ...
