Problems solved by technology

[0005] However, in the centrifugal spinning method described in Patent Document 1, there is a problem of occurrence of a defective phenomenon called multi-layer rewinding. The yarn is also lifted together with the uppermost yarn layer of the cake so that multiple yarn layers are rewound onto the bobbins at once
If multi-layer rewinding occurs, it will cause a large amount of yarn to be wound on the bobbin, and the problem that it cannot be unwound in the subsequent process

Embodiment Construction

[0026] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0027] First, the centrifugal spinning frame according to the embodiment of the present invention will be described.

[0028] figure 1 It is a schematic diagram which shows the structural example of the upper part rather than a tank of the centrifugal spinning frame which concerns on embodiment of this invention.

[0029] like figure 1 As shown, the centrifugal spinning frame 1 includes a draft device 10 , a yarn guide 11 , a tank 12 , and a bobbin support 13 . Furthermore, these structural elements constitute one spindle which becomes one unit of spinning. The centrifugal spinning frame 1 has a plurality of spindles, but figure 1 The structure of one of the spindles is described in .

Abstract

The bobbin (25) and the rewinding mechanism of the present invention enter into the tank (12) through the opening (23) of the tank (12). Next, a contact step is performed. Each elongated member (73) moves in the horizontal direction. In the can (12) where yarn breakage is detected, the elongated member (73) is lifted in advance, thereby pressing and contacting the inner wall (22) of the can (12). Next, move on to the step. The bobbin (25) and elongated part (73) rise. As a result, the end of the elongated member (73) is pressed and brought into contact with the lower end portion 28b of the cake.

Description

technical field [0001] The invention relates to a rewinding method of a centrifugal spinning frame when the yarn is broken. Background technique [0002] As a worsted spinning method, a centrifugal worsted spinning method using a cylindrical tank is known. In the centrifugal spinning method described in Patent Document 1, a cylindrical bobbin is arranged on the outer side of the yarn guide bobbin coaxially with the yarn guide bobbin. Then, while twisting the yarn spun from the yarn guide, the yarn is wound around the inner wall of the can to form a yarn cake, and then the rewinding of the yarn to the bobbin is started. [0003] If the yarn breaks for some reason during spinning, the yarn is re-started to the bobbin by bringing the blade of the threading member into contact with the yarn cake formed on the inner wall of the can to lift the yarn from the cake. 's rollback. [0004] Patent Document 1: Japanese Patent Laid-Open No. 11-256434 [0005] However, in the centrifu...
