The loom equipment with broken yarn recognition of this embodiment, it includes first minute roller 1, second minute roller 2, image recognition device 3, warp beam 5, guide roller 6 and several warp 4. The first yarn dividing roller and the second yarn dividing roller are axially the same, and the first yarn dividing roller 1 and the second yarn dividing roller 2 are adjacent and arranged at intervals. The warp beam 5 is located on the side of the first yarn dividing roller 1 away from the second yarn dividing roller 2. The axial direction of the yarn guide roller shaft 6 is consistent with the axial direction of the warp beam 5. The yarn guide roller shaft 6 is positioned between the warp beam 5 and the first cross-plier 1. As shown in fig. 1, it is schematically shown that the first yarn dividing roller 1 and the second yarn dividing roller are located at the same height, the upper end of the yarn guiding roller shaft 6 is located at a position close to the same height as the first yarn dividing roller 1, and the warp beam 5 is located obliquely below the side of the yarn guiding roller shaft 6 far from the first yarn dividing roller 1. One end of each of the warp yarns 4 is sequentially wound on the warp beam 5 along the axial direction of the warp beam 5, the other end of each of the warp yarns 4 passes through the yarn guide roller shaft 6, namely, the warp yarns pass through the space between the first cross lapel 1 and the second cross lapel 2 after passing through the upper part of the yarn guide roller shaft 6, the warp yarns 4 are sequentially distributed along the length direction of the first cross lapel 1 or the length direction of the second cross lapel 2, and the length direction of each of the warp yarns 4 is vertical to the length direction of the first cross lapel 1 or the length direction of the second cross lapel 2. During operation of the weaving machine, the warp threads 4 will move with a certain tension in the feed direction 43 shown in fig. 1. In other words, the warp yarn 4 passes through the space between the first yarn dividing roller 1 and the second yarn dividing roller 2, one end of the warp yarn 4 extends in the direction of the first yarn dividing roller 1 away from the second yarn dividing roller 2 and is wound around the warp beam 5, and the other end of the warp yarn 4 extends in the direction of the second yarn dividing roller 2 away from the first yarn dividing roller 1.

The warp 4 is evenly divided into two layers which respectively bypass the first yarn dividing roller 1 and the second yarn dividing roller 2. That is, a part of the warp yarns 4 pass through the upper part of the first yarn distribution roller 1 and then pass through the lower part of the second cross lapel 2, and another part of the warp yarns 4 pass through the lower part of the first yarn distribution roller 1 and then pass through the upper part of the second cross lapel 2, as shown in fig. 2 or 3. The warp yarn 4 comprises a number of upper layer warp yarns 41 and a number of lower layer warp yarns 42. The upper warp yarns 41 and the lower warp yarns 42 are alternately arranged along the length direction of the warp beam 5. The upper layer warp 41 is located above the first cross-plier leno 1 and below the second cross-plier leno 2, and the lower layer warp 42 is located below the first cross-plier leno 1 and above the second cross-plier roller 2.

The working direction of the image recognition device 3 faces the first yarn distributing roller 1 and the second yarn distributing roller 2. The weaving machine device is also provided with a processing device, and the image recognition device 3 is in communication connection with the processing device. The image recognition device 3 is preferably a high-speed camera, and can continuously take pictures at set time intervals and transmit the taken influence data to the processing device for comparison and analysis. As shown in fig. 1, it is adaptively shown that the image recognition device 3 is arranged right above the first distribution roller 1 and the second distribution roller 2, and the working direction of the image recognition device 3 is downward toward the warp yarns 4 on the first distribution roller 1 and the second distribution roller 2. When there is a warp 4 broken or slackened, the arrangement of the warp 4 at the two yarn separating rollers is changed due to the tension change, and a missing or slackened warp is formed. The image recognition device 3 can determine the position of the broken or loose warp 4 by capturing the images before and after the broken warp 4 and comparing the difference.

The technical solution of the present application will be further explained with reference to the accompanying drawings.

As shown in fig. 3, the warp yarn 4 is divided into an upper layer warp yarn 41 and a lower layer warp yarn 42 after passing through the yarn guide roller 6, and alternately passes around the first yarn distribution roller 1 and the second yarn distribution roller 2, and the image recognition device 3 such as a high-speed camera captures an image as shown in fig. 4. The warp yarns 4 are evenly distributed on the two yarn-separating rollers. When there is a breakage of the warp 4, the arrangement of the warp 4 on one of the divided rollers is changed as shown in a circle a in fig. 5. The image recognition device 3 such as a high-speed camera continuously photographs at a constant frequency, and the captured image in fig. 5 is uploaded to a processing device and compared with the image in fig. 4 to detect the presence of the broken ends of the warp yarns 4. Similarly, alignment differences may also occur if warp yarns 4 relax, as shown in figure 6 within circle B.
