Problems solved by technology

[0006] However, Patent Document 2 does not disclose a spinning machine equipped with a piecing device.
In this layout, since the upstream and downstream yarn paths of the yarn accumulating device are quite different, it is considered that it is difficult to guide the spun yarn to the yarn accumulating device after the start of piecing.

Embodiment Construction

[0036] Next, a spinning frame (spinning machine) according to an embodiment of the present invention will be described with reference to the drawings. In this specification, "upstream" and "downstream" mean upstream and downstream in the running direction of the fiber bundle and spun yarn during spinning.

[0037] The spinning frame includes a plurality of spinning units arranged in parallel, and a body control device (not shown) that collectively manages the spinning units. Each spinning unit 2 spins the fiber bundle 8 sent from the drafting device 7 by the spinning device 9 to produce a spun yarn 10 , and the winding unit 26 winds the spun yarn 10 to form a package 50 .

[0038] 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 spinning unit 2...

Abstract

A spinning machine includes a spinning device (9), a winding section (26), a yarn pooling device (22), a yarn joining device (23), a transporting device, and a movable guide (60). The winding section forms a package (50). The yarn pooling device (22) pools the spun yarn (10) between the spinning device (9) and the winding section (26). The yarn joining device (23) joins the spun yarns (10). The transporting device transports the spun yarn (10) to the yarn joining device (23). The yarn pooling device (22) changes a direction of a first yarn path. The yarn pooling device (22) is arranged at a position away from the second yarn path. The movable guide (60) pulls the spun yarn (10) on the second yarn path to the yarn pooling device (22).

Description

technical field [0001] The present invention relates to a spinning machine in which the directions of the yarn paths on the upstream side and the downstream side of the yarn accumulating device are greatly different. In detail, it relates to a structure for appropriately performing piecing in the spinning machine of this layout. Background technique [0002] Conventionally, a spinning machine is known that includes a yarn accumulating device for temporarily accumulating the spun yarn by winding the spun yarn around a rotating roller. Such a spinning machine is disclosed in JP-A-2004-277944 (Patent Document 1). [0003] The spinning machine of Patent Document 1 includes a piecing cart including a piecing device for piecing the spun yarn from the spinning device and the spun yarn from the package. If a certain spinning unit breaks the yarn, or the yarn quality monitoring device detects a yarn defect and cuts the yarn with a cutter, the piecing trolley travels to the spinning...
