Embodiment Construction

[0024] Hereinafter, the doffing device of the present invention and an automatic winder having the same will be described based on the drawings.

[0025] [Structure] First, the structure of the automatic winder 1 of this embodiment will be described. Such as figure 1 and figure 2 As shown, the automatic winder 1 has: a plurality of winding devices (winding units) 2 arranged in parallel; a yarn feeding bobbin supply device 3 for supplying a yarn feeding bobbin B to each winding device 2; The doffing device 6 for the doffing operation of the device 2; the conveying device 12 for transporting the wound package P doffed by the doffing device 6; the control device 8 for controlling each winding device 2 and the doffing device 6, etc. .

[0026] Such as figure 2 As shown, the winding device 2 winds the yarn Y unwound from the yarn supplying bobbin B on the winding bobbin 9 to form a winding package P. The upper part of the winding device 2 is provided with: a cradle arm (windi...

Abstract

A doffing apparatus (6) includes a chuck (66) that supplies a winding tube (9) to a winding-tube support member (21) of a winding unit (2), a restricting lever (71) that comes into contact with a first-side end portion (9a) of the winding tube (9) to restrict a position of the first-side end portion (9a), and a pressing lever (72) that comes into contact with a second-side end portion (9b) of the winding tube (9) restricted by the restricting lever (71) and presses the second-side end portion (9b) against the restricting lever (71). The winding tube (9) held by the chuck (66) is positioned by the restricting lever (71) and the pressing lever (72).

Description

technical field [0001] The present invention relates to a doffing device included in a textile machine such as an automatic winder, and specifically relates to a doffer capable of accurately positioning a winding bobbin disposed at a take-out port of a winding bobbin stocker at a predetermined position . Background technique [0002] Such as figure 2 As shown, the doffing device 6 included in the automatic winder or the like is installed freely movable in the parallel arrangement direction of the winding devices 2, and the fully wound winding package P is rolled backward by opening the cradle arm 21, and placed on the transport device 12 . Then, the winding bobbin 9 stored in the box-shaped winding bobbin storage 65 is grasped by the chuck 66, supported on the cradle arm 21, and the yarn Y of the yarn supplying bobbin B Hang on this winding bobbin 9, start winding again. [0003] However, winding bobbins used in automatic winders and the like may vary in axial length by ...
