Embodiment Construction

[0037] Embodiments will be described in detail below with reference to the drawings. In addition, in each figure, the same reference numerals are assigned to the same or corresponding parts, and repeated explanations will be omitted.

[0038] Such as figure 1 As shown, a spinning machine (yarn winding machine) 1 includes a plurality of spinning units 2, a yarn joining cart 3, a doffing cart (not shown), a first end frame 4, and a second end frame 5. A plurality of spinning units 2 are arranged in a row. Each spinning unit 2 produces a yarn Y and winds it into a package P. The yarn joining cart 3 performs a yarn joining operation in a certain spinning unit 2 when the yarn Y is cut in the spinning unit 2 or the yarn Y is disconnected for some reason. The doffing trolley doffs the package P and supplies a new bobbin B to the spinning unit 2 when the package P is fully wound in a certain spinning unit 2 .

[0039] The first end frame 4 accommodates a recovery device and the like...

Abstract

The invention provides a yarn monitoring device and a yarn winding machine. The yarn monitoring device is a device configured to monitor traveling yarn. The yarn monitoring device includes a discrimination section. The discrimination section discriminates the type of a yarn defect of the yarn, based on a combination of the thickness of the yarn and the brightness of reflected light that has been reflected by the yarn when the yarn has been irradiated with light.

Description

technical field [0001] The present invention relates to a yarn monitoring device and a yarn winding machine. Background technique [0002] As a technique related to a yarn monitoring device, a yarn clearer described in Japanese Patent No. 5413560 is known. In the yarn clearer described in Japanese Patent No. 5413560, the thickness of the spun yarn is detected by measuring light (transmitted light) partially blocked by the spun yarn (yarn). In addition, in the yarn clearer described in Japanese Patent No. 5413560, foreign matter contained in the spun yarn is detected by measuring reflected light reflected by the spun yarn. [0003] There are various types of yarn defects, and in the above-mentioned yarn monitoring device, it may be difficult to distinguish the types of such yarn defects, and it may be difficult to determine the yarn defects with high accuracy. Contents of the invention [0004] Therefore, an object of the present invention is to provide a yarn monitoring ...
