Embodiment 1

[0027] Embodiment 1: When N=4, C=2, the color difference is CIEDE94.

[0028] A method for identifying a different-color spun bobbin, the steps are as follows:

[0029] Step 1: When the bobbin passes through the pallet track and is located in the bobbin recognition system, the color information of the current spun bobbin is obtained through the color sensor of the bobbin recognition system, and the light intensity sensor obtains the ambient light at this time and transmits the signal to the bobbin Microcontroller 4 of the tube identification system;

[0030] Step 2: The microcontroller 4 identifies and analyzes the collected color information to determine whether the current bobbin is a bobbin of a different color. If it is a bobbin of an abnormal color, a warning signal is issued, and if not, continue to the first step.

[0031] The identification and analysis in the second step, the specific steps are:

[0032] 2.1 Calibration stage:

[0033] 2.1.1 Use 4 color sensors to ...

Embodiment 2

[0044] Embodiment 2: When N=7, C=3, the color difference is CIE2000.

[0045] A method for identifying a different-color spun bobbin, the steps are as follows:

[0046] Step 1: When the bobbin passes through the pallet track and is located in the bobbin recognition system, the color information of the current spun bobbin is obtained through the color sensor of the bobbin recognition system, and the light intensity sensor obtains the ambient light at this time and transmits the signal to the bobbin Microcontroller 4 of the tube identification system;

[0047] Step 2: The microcontroller 4 identifies and analyzes the collected color information to determine whether the current bobbin is a bobbin of a different color. If it is a bobbin of an abnormal color, a warning signal is issued, and if not, continue to the first step.

Abstract

The invention belongs to the technical field of automatic textile detection, and particularly relates to an abnormal-color spun yarn bobbin identification method. The method includes the following steps: first step, when a bobbin passes through a tray track and is located at a bobbin identification system, obtaining color information of the current spun yarn bobbin through a color sensor of the bobbin identification system, obtaining a current environment lighting situation by a light intensity sensor, and transmitting a signal to a microcontroller of the bobbin identification system; and second step, identifying and analyzing the collected color information by the microcontroller, judging whether the current bobbin is an abnormal-color bobbin, issuing a warning signal if the same is the abnormal-color bobbin, and otherwise, continuing the first step. The method can support a coordinated working scheme of a single color sensor or multiple color sensors, overcomes interference of external light beams, and improves abnormal-color spun yarn bobbin color identification robustness, flexibility and intelligence. According to the method, cost is low, maintenance is easy, a function of on-line monitoring on spun yarn bobbin transportation tracks can be realized, and a winding process automation degree is improved.

Description

technical field [0001] The invention belongs to the technical field of textile automatic detection, and in particular relates to a method for identifying a different-color spun bobbin. Background technique [0002] In the field of textile yarn processing, the yarns spun by the spinning frame are usually in different colors, so that the operator can quickly distinguish different yarn products. With the automation and continuous development of the spinning process, the yarn spun by the spinning frame has been automatically collectively doffed, and is automatically transported to the winding process by pallet rails for winding. However, the winding process involves a huge number of bobbins, which are easy to mix bobbins of different colors, that is, bobbins of different colors. Since the different-color bobbin represents different yarn varieties, if not found in time, the yarn of the different-color bobbin will be wound into the package yarn, which will directly lead to the fa...
