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 machine (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 traveling 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 machine control device that is not shown in the figure for collectively managing 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 spun yarn 10 is wound by the winding section 26 to form a package 50.

[0038] Such as figure 1 As shown, each spinning unit 2 includes a drafting device 7, a spinning device 9, a yarn accumulating device 22, a yarn joining device 23, a yarn monitoring device 25, and a winding unit 26 arranged in this order from upstream to downstream. Each part of...

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. The winding section (26) forms a package (50) by winding spun yarn (10) generated by the spinning device (9) onto a winding tube (51). 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) at the spinning device (9) side and the winding section (26) side. 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 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 having a layout in which the directions of the yarn paths on the upstream side and the downstream side of a yarn accumulating device are greatly different. In detail, it relates to the structure for appropriately performing piecing in the spinning machine of this layout. Background technique [0002] Conventionally, we have known spinning machines equipped with a yarn accumulating device that winds spun yarn around a rotating roller and temporarily accumulates the spun yarn. Japanese Patent Laid-Open No. 2004-277944 (Patent Document 1) discloses such a spinning machine. [0003] The spinning machine of Patent Document 1 includes a yarn joining cart equipped with a yarn joining device that joins a spun yarn from a spinning device and a spun yarn from a package. If a yarn breakage occurs in a spinning unit, or the yarn quality monitoring device detects a yarn defect and cuts the yarn with a cutter, the yarn ...
