Large round machine knitting needle triangle detection system and detection method

Abstract

The invention relates to a large round machine knitting needle triangle detection system. The system comprises a first conveying unit, an image acquisition unit, an image processing module, a knittingneedle, a resistance sensor and a determination module, wherein the first conveying unit is used for making a large round knitting needle triangle linearly move from the first position to the third position through the second position, the image acquisition unit is used for acquiring an image of the large round knitting needle triangle moved to the second position, the image processing module isused for acquiring geometric parameters of the large round knitting needle triangle according to the acquired image of the large round knitting needle triangle, the knitting needle can be matched witha groove, the knitting needle is formed between the second position and the third position through moving in the second direction orthogonal to the first direction to pass through the groove when thelarge round knitting needle triangle moves linearly, the resistance sensor is used for detecting the resistance of the knitting needle passing through the groove of the large round knitting needle triangle, and the determination module is used for determining whether the large round knitting needle triangle is qualified according to the geometric parameters and the resistance of the large round knitting needle triangle. The system is advantaged in that automatic detection of the large round knitting needle triangle can be realized, and detection reliability can be improved.

Description

technical field [0001] The invention relates to a large circular machine knitting needle cam detection system and a large circular knitting needle cam detection method. Background technique [0002] Circular knitting machine is a kind of circular weft knitting machine, which is the main production equipment in the knitting industry. Large circular machine knitting needle triangle, also known as large circular machine knitting needle mountain angle, large circular machine knitting needle water chestnut, is to control the reciprocating movement of knitting needles and sinkers in the cylinder groove according to the different needs of large circular machine knitting varieties. Such as Figure 5 As shown, the surface of the triangle P of the large circular knitting needle is formed with a triangular curved groove S (also called a needle track) extending from one end to the other end, and the main part of the knitting needle is in the needle groove of the large circular machine n...
