Problems solved by technology

[0005] However, in the centrifugal spinning machine described in Patent Document 1, in order to rewind the yarn when the yarn is broken, the entire yarn unwinding member is raised and inserted into the inside of the tank, so there is a problem of increasing the size of the entire device. question

Embodiment approach 2

[0135] Next, the configuration of the centrifugal spinning frame according to Embodiment 2 of the present invention will be described. In addition, in Embodiment 2, with Figure 1 to Figure 15 The same reference numerals denote the same or the same structural elements, and therefore detailed descriptions thereof are omitted.

[0136] The configuration of the centrifugal spinning frame according to the second embodiment is different from that of the first embodiment in that the distal end portion of the elongated member is elastically supported by the proximal end portion.

[0137] Figure 16 An outline of the elongated member 73 according to the second embodiment is shown. The front end portion 73a of the elongated member 73 is elastically supported by the base end portion 73b by the compression spring 73c. The compression spring 73c constitutes an elastic support member. The base end portion 73b of the elongated member 73 is supported by the fixed fulcrum E. The other st...

Abstract

To provide a centrifugal spinning frame capable of further downsizing the structure for rewinding the yarn at the time of yarn breakage. The centrifugal spinning frame includes: an elongated member (73) having a front end (73a) capable of contacting an inner wall (22) of a tank (12) having an opening (23), and a base supporting the front end (73a). end portion (73b); lifting arm (76), which adjusts the position of the front end portion (73a) in the height direction to the position of the yarn end of the yarn (18) wound on the inner wall (22) of the tank (12); The second seat surface (43) and the third seat surface (44) of the filler seat (40), which clamp the elongated member (73) from the direction crossing the tilting direction, and guide the tilted elongated member (73) ; the front part (47) and the spring (48), which elastically support the front part (73a) with respect to the tilting direction; and the push rod (78), which makes the elongated part (73) tilt and makes the elongated part (73 ) abuts against the inner wall (33) of the tank (12).

Description

technical field [0001] The present invention relates to a centrifugal spinning frame, in particular, to a centrifugal spinning frame having a structure for rewinding the yarn when the yarn is broken. Background technique [0002] As one of the spinning frames, a centrifugal spinning frame using a cylindrical tank is known. In the centrifugal spinning machine described in Patent Document 1, a cylindrical bobbin is arranged coaxially with the yarn guide on the outer side of the yarn guide. Then, the yarn is wound around the inner wall of the can to form a cake while twisting the yarn spun from the yarn guide, and then the yarn is rewound to the bobbin again. [0003] When the yarn breaks for some reason during spinning, the yarn is restarted by abutting the blade of the yarn unwinding member against the yarn cake formed on the inner wall of the can to lift the yarn from the cake. Rewind to the bobbin. [0004] Patent Document 1: Japanese Patent Laid-Open No. 11-256434 [0...
