Abstract

The invention relates to a detection device and a detection method of the weft breakage of a double-axis warp knitting machine. The detection device comprises a programmable computer controller, an input/output module and an irreflexive photoelectric sensor, wherein the programmable computer controller is connected with the input/output module through communication; and the irreflexive photoelectric sensor comprises an infrared transmitter module and an infrared receiver module which are connected with the input/output module through communication respectively. The detection method using the detection device comprises: setting the rotation period TR of the spindle of the double-axis warp knitting machine as D/RI; setting a yarn hanging mode M; detecting if a weft is broken according to the detected position of the weft by the programmable computer controller; and when the programmable computer controller determines the weft is broken, stopping the machine (including emergently stopping the machine) and stopping the weft breakage detection function. The detection device of the invention is simple in structure; and the effect of the detection of weft breakage by the detection methodis desirable.

Description

technical field [0001] The invention relates to a yarn break detection device and a detection method for the weft yarn of a biaxial warp knitting machine. Background technique [0002] The weft yarn hook of biaxial warp knitting machine laying weft is 8 inches, and existing weft yarn hook has two kinds: every inch has 2 or 3 hanging yarn hooks. According to the technical requirements, one yarn can be hung on each weft yarn hook, or one yarn can be hung on every other weft yarn hook, that is, one empty one; in this way, the weft laying device can lay at most 8×2=16 or 8×3 at the same time. = 24 weft yarns, the laid weft yarns are arranged in sequence and sent to the machine head by the chain for weaving. At present, there are many yarn break detection devices in the textile industry, which are generally independent detection equipment, which consists of detection equipment and processing equipment. The detection equipment generally includes a lens emitter, a lens receiver, ...
