Embodiment Construction

[0026] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In addition, the same code|symbol is attached|subjected to the same or corresponding part in each figure, and the overlapping description is abbreviate|omitted. "Upstream" and "downstream" mean upstream and downstream in the traveling direction of the yarn at the time of yarn winding.

[0027] Such as figure 1 As shown, the automatic winder 1 includes a plurality of winder units (yarn winders) 10 arranged side by side, an automatic doffing device 80, and a machine control device 90 as main components. Each winding unit 10 winds the yarn 20 unwound from the yarn supplying bobbin 21 while reciprocating (traversing) to form a package 30 .

[0028] The automatic doffing device 80 advances to the position of each winder unit 10 when the package 30 in each winder unit 10 is full, and discharges the full package 30 from the winder unit 10 . The automatic doffing dev...

Abstract

A yarn winding machine, the winding unit (10) is equipped with: a cradle (23), which keeps the package (30) rotatable; a contact roller (29), which can contact the surface of the package (30); Cylinder (60) to move the package (30) between a position in contact with the contact roller (29) and a position away from the contact roller (29); upper yarn suction port (35) to move to approach the package (30) or away from the surface of the package (30), while catching the yarn end of the package (30); the angle sensor (44) detects the rotation angle of the cradle (23); the unit control part (50) ), control the movement of the upper yarn suction port (35). The unit control unit (50) moves the upper yarn suction opening (35) based on the rotation angle of the cradle (23) acquired by the angle sensor (44) so ​​that it is close to the distance from the package (30) when it is lifted. The surface is where the distance is set.

Description

technical field [0001] The present invention relates to yarn winding machines. Background technique [0002] As a conventional yarn winding machine, for example, a yarn winding machine described in JP 2010-13259 A is known. In this yarn winding machine, when the yarn is cut during the yarn winding operation, after the package is separated from the contact roller by driving the air cylinder (so-called liftup), The yarn end of the package is caught by moving the suction nozzle by a constant amount so as to approach the surface of the package. [0003] In such a yarn winding machine, the lifting amount (the amount by which the package is separated from the touch roller) can be accurately adjusted so that the distance from the touch roller to the surface of the package is always constant during lifting. [0004] However, in the above-mentioned yarn winding machine, there is a possibility that the lifting amount varies, and the yarn end of the package cannot be reliably caught....
