[0075] figure 1 A core yarn spinning machine 1 including a plurality of spinning units 2 arranged in parallel is shown. The spinning machine 1 is equipped with a piecing cart (service device) 3 , a blower box 4 , and a prime mover box 5 , which are provided to move freely along the direction in which the spinning units 2 are arranged.

[0076] Such as figure 1 As shown, each spinning unit 2 includes a draft device 7, a spinning device 9, a yarn feeding device 11, and a winding device 12 as main components. The draft device 7 is provided near the upper end of the casing 6 of the main body of the spinning machine 1, and is configured so that the fiber bundle 8 sent from the draft device 7 is spun by the spinning device 9. The spun yarn (core spun yarn) 10 discharged from the spinning device 9 is conveyed downward, and passes through a yarn clearer (yarn defect detector, The yarn monitoring mechanism) 35 is wound by the winding device 12 on a bobbin serving as a winding tube...

Abstract

A core yarn spinning machine (1) having a spinning apparatus (9) spinning a core yarn and a winding device (12) winding up the spun core yarn (10), comprising a slab catcher (35) determining the presence or absence of the core of the core yarn (10). In the spinning apparatus (9), the spun core yarn (10) is led into the slab catcher (35) in a pre-winding time from the start of the spinning of the core yarn (10) to the start of winding of the core yarn (10) by the winding device (12). When the core yarn is led into the slab catcher, the presence of the core is explicated more than in a time after the winding of the core yarn (10) is started by the winding device (12).

Description

technical field [0001] The present invention relates to a core-spun spinning machine capable of judging the presence or absence of a core yarn. Furthermore, the present invention relates to a core yarn presence / absence determination method for determining whether or not a core yarn has entered a core-spun yarn. [0002] Furthermore, the present invention relates to a method of performing certain services in a core yarn spinning machine. [0003] Background technique [0004] The core-spun yarn spinning mechanism disclosed in Patent Document 1 is such that the elastic yarn as the core yarn supplied from the elastic yarn supply device and the fiber bundle (sheath fiber) drafted by the draft device are air-spun by the air spinning device. Spinning to produce a core-spun yarn with a structure in which the core yarn is wrapped with sheath fibers. In addition, this core yarn spinning machine is equipped with a winding device for winding the core yarn into a package, and a yarn c...
