Embodiment Construction

[0042] Next, a spinning frame (winding frame) according to an embodiment of the present invention will be described with reference to the drawings. In addition, "upstream" and "downstream" in this specification refer to upstream and downstream in the moving direction of the yarn during spinning. figure 1It is a front view showing the structure of the whole spinning frame 1.

[0043] figure 2 It is a longitudinal sectional view of the spinning frame 1.

[0044] as figure 1 The spinning frame 1 of the shown winder includes a plurality of spinning units 2 arranged side by side. The spinning frame 1 includes a yarn joining cart 3 , a doffing cart 4 , a blower box 93 , and a prime mover box 5 .

[0045] Such as figure 1 As shown, each spinning unit 2 mainly includes a draft device 7, a spinning device 9, a yarn storage device 12, and a winding device 13 arranged in the following order from upstream to downstream. The draft device 7 is provided near the upper end of the frame...

Abstract

A doffer (60) includes support members (65) and a bobbin guiding cylinder (62). The support members (65) support a package formed by winding a spun yarn on a bobbin. The bobbin guiding cylinder (62) drives the support members (65) to convey a fully wound package supported by the support members (65) from a position (first position) of the package at which the support members (65) receive the package that is fully wound to a position of a package receiving section (84) (second position).

Description

technical field [0001] The invention mainly relates to doffing devices for discharging packages Background technique [0002] Conventionally, it is known that a winding machine such as a spinning machine is provided with a doffing device for discharging a fully wound package or the like. Such winding machines (spinning machines, textile machines) are disclosed in JP-A-9-100066 and JP-A-2005-220484. [0003] In the spinning machine disclosed in Japanese Patent Application Laid-Open No. 9-100066, a package loading area is provided between the spinning unit and the doffing carriage. The full package wound by the spinning unit is taken out by the guide arm part of the doffing trolley from the cradle holding the bobbins. The guide arm member temporarily receives the package through the support plate, and then drops the package toward the package loading area. [0004] In the textile machine disclosed in Japanese Patent Application Laid-Open No. 2005-220484, a loading area is p...
