Problems solved by technology

That is, this sensor does not manage to detect a very small amount of yarn remaining on the yarn accumulating roller after the yarn is cut (for example, a small amount of yarn scraps wound around the yarn accumulating roller for about 1 to 2 turns).

Embodiment Construction

[0025] Next, embodiments of the present invention will be described. Such as figure 1 As shown, a spinning machine (spinning machine) 1 (yarn winding machine) is equipped with a plurality of spinning units (spinning units) 2, a yarn splicing cart (yarn splicing cart) 3, and a blower box (blower box). )4 and power box (motor box)5.

[0026] Such as figure 1 with figure 2 As shown, each spinning unit 2 includes a draft device 6, a spinning device 7, a cutter 10 (cutting device), and a yarn clearer 11. (yarn defect detecting device), slack eliminating device (slack eliminating device) 8 (yarn accumulating device), and winding device (winding device) 12 and the like. In addition, in the following description, "upstream" and "downstream" refer to upstream and downstream in the yarn running direction during spinning.

[0027] The draft device 6 is provided near the upper end of the casing 13 of the main body of the spinning frame 1 . The sliver 14 sent to the drafting device ...

Abstract

A spinning machine (1) includes a winding device (12) and a slack eliminating device (8). The slack eliminating device (8) includes a slack eliminating roller (30) and a yarn detecting sensor (34). The yarn detecting sensor (34) is a reflective photo sensor having a light emitting element (41) and a light receiving element (42). An opening provided for the light emitting element (41) has a prescribed width such that a width of an irradiated range on the slack eliminating roller (30) is substantially equal to a thickness of the yarn (16).

Description

technical field [0001] The present invention relates to a yarn winding machine for winding traveling yarn to form a winding package. Background technique [0002] A conventionally known yarn winding machine has a winding device (winding device) that winds and travels the yarn to form a package, and a yarn accumulator that temporarily stores the yarn wound by the winding device Device (yarn accumulating device). For example, a spinning machine described in Patent Document 1 includes a spinning device, a winding device, a yarn clearer, a cutter, and a yarn accumulating device. ) (yarn slack eliminating device). The winding device winds the yarn sent from the spinning device into a package. The yarn clearer checks the yarn for defects before it is wound onto the package. When the yarn clearer detects a yarn defect, the cutter cuts the yarn. The yarn accumulating device is disposed between the winding device and the cutter. That is, the yarn accumulating roller is arranged...
