Problems solved by technology

[0006] However, in the spinning unit that uses the air actuator to move the spinning section, the characteristics of the spinning may change due to malfunction of the air actuator (shrinkage failure due to air leakage, etc.)
Specifically, when the position of the spinning section relative to the draft section is misaligned or the position of the spindle of the spinning section is misaligned due to malfunction of the air actuator, the characteristics of spinning may change.

Embodiment Construction

[0036] First, the overall structure of the spinning unit 100 will be briefly described. figure 1 The shown black arrows indicate the feeding directions of the fiber bundle F and the spun yarn Y. The spinning unit 100 is a spinning machine that produces a spun yarn Y from a fiber bundle F to form a package P. The spinning unit 100 includes a sliver supply unit 1, a draft unit 2, a spinning unit 3, a yarn defect detection unit 4, a tension stabilizing unit 5, and a winding unit 6 along the feeding direction of the fiber bundle F and the spun yarn Y.

[0037] The sliver supply unit 1 supplies the fiber bundle F (sliver) to the draft unit 2 . The sliver supply unit 1 includes a creel 11 and creels (not shown). The fiber bundle F stored in the creel 11 is guided by the creel and guided to the drafting unit 2 .

[0038] The drafting unit 2 drafts the fiber bundle F to make the thickness of the fiber bundle F uniform. The drafting unit 2 includes four sets of drafting roller pair...

Abstract

A spinning unit includes a drafting section (2) adapted to draft a fiber bundle (F), a spinning section (3) adapted to twist the fiber bundle (F) drafted by the drafting section (2), a pneumatic actuator (38) adapted to move the spinning section (3) in a direction away from the drafting section (2), and an elastic member (39) adapted to move the spinning section (3) in a direction towards the drafting section (2).

Description

technical field [0001] The present invention relates to the technology of spinning unit and spinning machine. Background technique [0002] Conventionally, a spinning unit is known that produces a spun yarn by drafting a fiber bundle and twisting the drafted fiber bundle (see, for example, JP-A-2011-99192). Such a spinning unit is provided with a drafting section that drafts a fiber bundle and a spinning section that twists the drafted fiber bundle. [0003] The draft section includes a plurality of draft roller pairs. The draft roller pair is composed of a bottom roller rotated by a power mechanism and a top roller driven to rotate while in contact with the bottom roller. Since the drafting roller pair rotates while the fiber bundle is held by the bottom roller and the top roller, the fiber bundle can be sent out. The drafting unit can draft the fiber bundle by the difference in delivery speed between the draft rollers adjacent to each other. [0004] The spinning secti...
