Problems solved by technology

[0004] However, since, for example, a very long length of wire is wound in a wire winding machine, even if the error in the detection of the wire travel speed by the wire travel information acquisition device is extremely small, the error in the length of the wound wire will be large.

Embodiment Construction

[0034] Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

[0035] figure 1 as well as figure 2 The shown winding unit (thread processing device) 10 winds the spun yarn 20 unwound from the yarn supply bobbin 21 by the take-up bobbin 22 while traversing, thereby forming a package of a predetermined shape with a predetermined length. 30. The automatic winding machine according to this embodiment has a plurality of winding units 10 arranged side by side, and an unillustrated body control device arranged at one end in the side-by-side direction.

[0036] Each winding unit 10 is provided with the unit frame 11 ( figure 1), and the winding unit main body 16 arranged on the side of the unit frame 11 . The winding unit main body (wire processing unit) 16 includes a winding unit 31 . The winding unit main body 16 includes a magazine type supply device 60 and a yarn supply bobbin holder 71 .

[0037] Such as figure 1 As ...

Abstract

The present invention relates to a device for acquiring thread traveling information, comprising: a first thread unevenness sensor (43) that detects the thickness unevenness of a traveling thread and outputs a first thread thickness uneven signal; detects the thread thickness unevenness and outputs a second thread thickness A second line unevenness sensor (44) for an uneven signal; based on the first line thickness unevenness signal acquired during a predetermined first time range and acquired during a second time range longer than the first time range The second uneven thickness signal of the second line is used to obtain the similarity evaluation part (65) of a plurality of similarities between the first uneven thickness signal and the second uneven thickness signal; The speed of the deviation of the signal and the uneven thickness signal of the second line is compared to the weight coefficient specified by the corresponding weighting curve, and performs weighting processing on multiple similarities respectively, and calculates a weighting processing unit (66) for multiple weighted similarities; based on A travel information acquisition unit that obtains travel information of a line by weighting the similarity.

Description

technical field [0001] The present invention relates to a wire travel information acquisition device that detects the state of a running wire. Background technique [0002] In a wire winding machine for wire winding, information about the running state of the wire may be required for controlling wire winding and the like. Then, such a winding machine includes a wire traveling information acquisition device for acquiring information (wire traveling information) related to the traveling state of the wire. As the above-mentioned running state, for example, the wire running speed and the like are considered. [0003] As such a line travel information acquisition device, for example, there is a device described in JP-A-2012-051672. The wire travel information acquisition device disclosed in this document includes two wire thickness unevenness sensors for detecting wire thickness unevenness, and samples signals detected by the two wire thickness unevenness sensors at a predeterm...
