Embodiment Construction

[0024] Hereinafter, the yarn unwinding assisting device of the automatic winder (hereinafter simply referred to as the yarn unwinding assisting device) of the present invention will be described.

[0025] Such as figure 1 As shown, the automatic winder includes a plurality of winding devices 2 arranged in a straight line. The automatic winder includes a bobbin supply device 6 for supplying the bobbin B to each winding device 2, and a doffing device 7 for performing a doffing operation. Further, the automatic winder includes a machine control device 8 that controls each of the winding devices 2, the bobbin supply device 6, the doffing device 7, and the like.

[0026] Such as figure 2 As shown, in the winding device 2, a yarn unwinding auxiliary device 1, a tension device 22, a piecing device 23 and a yarn clearer 24 are sequentially arranged from the bottom to the top. Furthermore, the winding device 2 includes: a traverse drum 25 for reciprocating the yarn Y within a const...

Abstract

A yarn unwinding assisting device (1) is provided with a yarn unwinding assisting unit (U) including a fixed cylinder (first regulating cylinder) (11), a movable cylinder (second regulating cylinder) (13) and a moving structure (4) for moving the movable cylinder (13), and a height adjusting structure (5) for adjusting a height position of the yarn unwinding assisting unit (U) in a direction of a yarn path. The height adjusting structure (5) includes a shaft (50) extendedly fixed in the direction of the yarn path, a clamping member (51) that is attached to the yarn unwinding assisting unit (U), moves along the shaft (50) and can clamp the shaft (50), and an operation lever (52) to manipulate the clamping member (51) to clamp or release the shaft (50).

Description

technical field [0001] The invention relates to a yarn unwinding auxiliary device, which is suitable for an automatic winder and assists the unwinding of yarn from bobbins. Background technique [0002] Such as figure 1 As shown, the automatic winder includes: a plurality of winding devices 2 that unwind the yarn Y of the bobbin B and wind it on the winding tube; The doffing device 7 and the like for doffing the package. Each winding device 2 is provided with a yarn unwinding auxiliary device that restricts the balloon formed when the yarn Y is unwound from the bobbin B and applies an appropriate tension to the yarn Y. , while assisting the unwinding of yarn Y. [0003] For example, if Figure 8 As shown, the conventional yarn unwinding assisting device 9 includes: a fixed cylinder 90 that is fixed when the yarn Y is unwound from the bobbin B; The movable cylinder 91; and the lifting mechanism 92 for lifting the movable cylinder 91, etc. The yarn unwinding auxiliary de...
