[0107] Example 4:

[0108] Based on Example 3, re-acquiring the first distance mainly includes the following steps:

[0117] Example 5:

[0118] Based on Example 3, a second analysis of the knitting deviation level at the current position is performed, which mainly includes the following steps:

[0123] Otherwise, there is no need to adjust the knitting deviation level corresponding to the first distance;

[0124] Step 33: Analyze and adjust the knitting deviation level of the current real-time knitting position based on the second analysis basis.

[0125] In this embodiment, the second sensor is a sensor that can measure the distance between the weft yarn that has not been successfully sucked by the yarn suction device and the yarn suction terminal of the yarn suction device.

[0127] In this embodiment, the preset level difference is determined based on the level range and the weft yarn adsorption accuracy. For example, the level difference can be divided into 10 levels according to the first ratio. If the range of the first distance corresponding to each level is small, the preset level difference can be set to 2.

[0133] Step 41: Using the knitting deviation level adjusted after the second analysis as a basis for adjusting the suction force of the target yarn absorber;

[0134] Step 42: Filter and determine the suction value of the yarn absorber corresponding to the current knitting deviation level from the level-suction database;

[0135] Step 43: comparing the suction value of the yarn absorber with the real-time suction value of the target yarn absorber, and determining a suction adjustment scheme based on the suction value comparison result, thereby automatically adjusting the suction of the target yarn absorber;

[0136] Step 44: re-adsorbing the weft yarn at the corresponding real-time weaving position based on the automatically adjusted target yarn absorber, and judging whether the weft yarn adsorption at the corresponding weaving position is successful, thereby determining the normal operation of the target yarn absorber.

[0137] In this embodiment, the grade-suction database refers to a database containing weaving deviation grades and suction values ​​corresponding to each grade.

[0138] In this embodiment, the suction force value of the yarn absorber refers to the suction force value of the yarn absorber required for the normal weft suction work of the yarn absorber, which is determined based on the level-suction force database and the real-time weaving deviation level.

[0139] In this embodiment, the real-time suction value refers to the real-time suction value of the target yarn suction device when sucking the weft yarn.

[0140] In this embodiment, the suction adjustment scheme refers to a suction adjustment scheme determined according to the difference between the suction value of the yarn absorber and the real-time suction value. For example, the suction adjustment scheme includes increasing or decreasing the suction value of the yarn absorber in a certain direction and a certain intensity.

[0141] The beneficial effect of the above technical solution is that by automatically adjusting the suction force of the corresponding yarn absorber according to the deviation level, the suction force of the yarn absorber can be made more accurate, so that the target yarn absorber can achieve high-speed and high-quality yarn suction.

[0142] Example 7:

[0143] Based on Example 6, judging whether the weft yarn adsorption at the corresponding weaving position is successful mainly includes the following steps:

[0144] Step 441: performing image acquisition of the corresponding weaving position based on a preset image acquisition device to determine whether a weft yarn head exists at the corresponding weaving position;

[0145] Step 442: If the weft yarn head does not exist at the corresponding weaving position, a first distance of the corresponding weaving position is measured based on the second sensor. If the first distance is not positive, it is determined that the weft yarn at the corresponding weaving position is successfully adsorbed.

[0146] The beneficial effect of the above technical solution is that by accurately judging the weft yarn adsorption result, the suction force of the yarn absorber can be determined more accurately, so that the target yarn absorber can achieve high-speed and high-quality yarn adsorption.
