Embodiment Construction

[0055] Next, a spinning frame (spinning machine) according to an embodiment of the present invention will be described with reference to the drawings. In addition, in this specification, "upstream" and "downstream" mean upstream and downstream in the running direction of a fiber bundle and a spun yarn during spinning.

[0056] The spinning frame includes a plurality of spinning units arranged in parallel, and a body control device that collectively manages the spinning units (not shown). Each spinning unit 2 spins the fiber bundle 8 sent from the draft device 7 by the spinning device 9 to generate a spun yarn 10 , and the winding unit 26 winds the spun yarn 10 to form a package 50 .

[0057] Such as figure 1 As shown, each spinning unit 2 includes a draft device 7, a spinning device 9, a yarn accumulating device 22, a yarn joining device 23, a yarn monitoring device 25, and a winding section 26 arranged sequentially from upstream to downstream. Each unit included in the spi...

Abstract

A yarn pooling device (22) includes a yarn pooling roller (41) and a yarn suction device (44). The yarn pooling roller (41) temporarily pools the spun yarn (10) by winding it on its outer circumferential surface. The yarn suction device (44) generates a suction air current at a suction port, which is arranged downstream of the yarn pooling roller (41) in the yarn running direction, to suck and dispose of the spun yarn (10) remaining on the yarn pooling roller (41). When disposing of the spun yarn (10) remaining on the yarn pooling roller (41), the yarn suction device (44) unhooks the spun yarn (10) that is hooked on a yarn hooking member (43) by using a suction pipe (71) and the like.

Description

technical field [0001] The present invention relates to a yarn accumulating device for removing (discarding) a yarn remaining on a yarn accumulating roller after yarn breakage. Background technique [0002] Conventionally, a spinning machine including a spinning device, a yarn accumulating device, and a winding device is known. The spinning device spins the fiber bundle drafted by the drafting device to spin a spun yarn. The yarn accumulating device temporarily stores the spun yarn spun from the spinning device. The winding device winds the spun yarn unwound from the yarn accumulating device into a package. The yarn accumulating device includes a yarn accumulating roller that winds the spun yarn around the outer periphery. The yarn accumulating device can prevent the spun yarn from slack by accumulating the spun yarn even if the spinning speed and the winding speed do not match for some reason. [0003] Next, suction and removal of the spun yarn on the yarn accumulating ...
