[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0029] The following disclosure provides many different embodiments or examples for implementing different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, reference numerals and / or letters can be repeated in different examples in the present application. Such repetition is for the purpose of simplification and clarity, and does not indicate the relationship between the various embodiments and / or settings discussed.

[0030] For ease of description, spatial relative terms can be used herein to describe the relative position relationship or movement condition of one element or feature with respect to another element or feature as shown in the drawings, such as "inner", "outer", "inboard", "outboard", "under", "below", "on", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the drawings. For example, if the device in the drawings is turned over or the posture is changed or the movement state is changed, the directional indications will also change accordingly, for example: the element described as "under" or "below" other elements or features will be oriented as "above" or "above" other elements or features. Therefore, the example term "below" can include both the upper and lower positions. The device can be additionally oriented (rotated by 90 degrees or in other directions) and the spatial relative relationship descriptors used herein are interpreted accordingly.

[0031] In order to solve the technical problems in the prior art, the application provides a loom, which can determine whether there is a weft in the photographed picture by setting a visual component and analyzing and judging, so that the control part makes whether to stop processing according to the detection result, has high accuracy, does not need workers to debug many times according to experience, is beneficial to simplify the process and reduce the operation difficulty, has high applicability to most wefts with different thicknesses, colors and materials, is beneficial to improve the ability of the same loom to process various wefts, and is not easily disturbed by impurities such as water, so that the autonomous stop of the loom is more accurate.

[0032] Figure 1The loom provided by the embodiment of the application comprises a loom body 1, a visual component 2, a control part 3 and a constraint mechanism 4. A detection area is arranged on one side of the loom body 1, and the detection area comprises a first detection area 5 and a second detection area 6. The second detection area 6 is arranged on the side of the first detection area 5 away from the loom body 1. The constraint mechanism 4 is arranged in the first detection area 5. The loom body 1, the visual component 2 and the constraint mechanism 4 are electrically connected to the control part 3. The visual component 2 is used for photographing the first detection area 5 and the second detection area 6, analyzing whether there is weft yarn in the photographed pictures and determining a weft yarn detection result. The control part 3 is used for determining whether to stop processing according to the weft yarn detection result. The constraint mechanism 4 is used for constraining the weft yarn sent to the first detection area 5 and releasing the constraint on the weft yarn to enable the weft yarn to participate in subsequent cloth winding operation when beating-up operation is performed. By arranging the visual component 2, whether there is weft yarn in the photographed pictures can be determined by analysis and judgment, so that the control part 3 makes whether to stop processing according to the detection result, which has high accuracy, does not need workers to debug multiple times according to experience, is beneficial to simplifying the process and reducing the operation difficulty, has high applicability to most weft yarns with different thicknesses, colors and materials, is beneficial to improving the ability of the same loom to process multiple weft yarns, and is not easily disturbed by impurities such as water, so that the autonomous stop of the loom is more accurate. By arranging the constraint mechanism 4, the weft yarn is temporarily constrained without cutting the weft yarn, so that the constraint without waste edges does not cause the situation that the twisting edge is weak and the cloth edge is loose, and the length of 5-10 cm of the weft yarn needs to be cut every time, which can save a large cost in the long term, is beneficial to promoting the development of enterprises in the direction of “reducing cost and increasing efficiency”, and since the weft yarn does not need to be cut and recycled, the setting of the waste edge yarn rotating winding mechanism, the weft yarn cutting mechanism, the waste edge yarn collecting mechanism, the storage mechanism and the like can be cancelled, so that the cost expenditure of the enterprise due to the setting of the structure is reduced.

[0033] In the application, the weft yarn detection result comprises a long weft result, a short weft result and a normal detection result. The long weft result is that there is weft yarn in the images photographed by the first detection area 5 and the second detection area 6. The short weft result is that there is no weft yarn in the images photographed by the first detection area 5 and the second detection area 6. The normal detection result is that there is weft yarn in the image photographed by the first detection area 5 and there is no weft yarn in the image photographed by the second detection area 6. The appearance of the long weft result and the short weft result will cause the length of each weft yarn to not meet the requirement of the loom, which is a defect and needs to be stopped for maintenance, so the control part 3 stops processing according to the long weft result or the short weft result.

[0034] Please continue to refer to Figure 1The loom body 1 comprises a weft insertion mechanism 7, a warp yarn feeding mechanism 8, a loom heald 9, a beat-up steel clip mechanism 10, a cloth roller 11 and a weft yarn twisting mechanism 12.

The warp yarn feeding mechanism 8 is arranged at one end of the loom heald 9 away from the beat-up steel clip mechanism 10. The weft insertion mechanism 7 is arranged at one side of both the beat-up steel clip mechanism 10 and the cloth roller 11. The weft yarn twisting mechanism 12 is arranged at the other side of both the beat-up steel clip mechanism 10 and the cloth roller 11. The weft insertion mechanism 7, the warp yarn feeding mechanism 8, the loom heald 9, the beat-up steel clip mechanism 10, the cloth roller 11 and the weft yarn twisting mechanism 12 are electrically connected to the control unit 3.

[0035] Referring to Figure 2 The vision assembly 2 comprises an image acquisition module 13, a vision analysis module 14 and a detection result determination module 15. The image acquisition module 13 is obtained by photographing the first detection area 5 and the second detection area 6 through the vision assembly 2. The vision analysis module 14 is used for inputting the image into an image processor, so that the image processor performs visual analysis processing on the weft yarn image and outputs a weft yarn result. The detection result determination module 15 is used for determining the weft yarn detection result according to the weft yarn result. The vision assembly 2 is connected to one side of the loom body 1. The weft yarn result includes whether there is weft yarn in the image photographed by the first detection area 5 or whether there is no weft yarn in the image photographed by the first detection area 5, and whether there is weft yarn in the image photographed by the second detection area 6 or whether there is no weft yarn in the image photographed by the second detection area 6. Based on a pre-trained weft yarn recognition model, the image is subjected to weft yarn recognition processing, wherein the weft yarn recognition mode includes but is not limited to a traditional image processing method, a machine learning-based method, a deep learning-based image classification method and a deep learning-based target recognition method, and is performed by collecting an image data set containing weft yarn and not containing weft yarn, wherein the images in the image data set are images photographed under different light conditions, backgrounds and weft yarn states, and the image data set contains various types of weft yarn, such as weft yarns of different thicknesses, colors and materials, and images under different backgrounds.

[0036] Referring to Figure 3 As a specific embodiment, the constraint mechanism 4 sends the weft yarn by suction adsorption, comprising a weft yarn placing portion 16 and a suction mechanism (not shown in the figure). An air inlet 18 is formed on the weft yarn placing portion 16, and the suction mechanism is in communication with the air inlet 18. When the weft yarn is sent into the weft yarn placing portion 16, the suction mechanism works to adsorb and constrain the weft yarn through the air inlet 18. Specifically, the weft yarn can be separated from the constraint mechanism 4 by controlling the suction adsorption strength or stopping the adsorption when the loom body 1 is working, so that the weft yarn can smoothly participate in subsequent operations.

[0037] Referring to Figure 4As a specific embodiment, the constraint mechanism 24 is a clamping structure, which can be an electromagnetic clamp, a pneumatic clamp, etc. The clamping structure clamps the weft yarn when it is working, and the weft yarn can be separated from the constraint mechanism 24 by controlling the clamping force or stopping clamping when the loom body 1 is working, so that the weft yarn can smoothly participate in subsequent operations.

[0038] Please refer to Figure 5 As a specific embodiment, the constraint mechanism 34 is a rotating brush structure, which winds the weft yarn when it is working. The weft yarn can be separated from the constraint mechanism 34 by adjusting the rotating speed of the rotating brush structure, the type of brush, and the tightness of the brush arrangement, so that the weft yarn can smoothly participate in subsequent operations.

[0039] Preferably, please continue to refer to Figure 1 The loom further comprises a cleaning mechanism 19 arranged on one side of the visual assembly 2. The cleaning mechanism 19 is connected with the control part 3, and the cleaning mechanism 19 cleans the lens of the visual assembly 2 under the control of the control part 3, so as to keep the lens clean, improve the clarity of the images collected by the shooting device, and reduce the possibility of the operation of the visual assembly 2 being disturbed by impurities on the lens. Specifically, the cleaning mechanism 19 comprises a liquid spraying assembly 20 and an air spraying assembly 21. The liquid spraying assembly 20 sprays liquid, which can be pure water or cleaning liquid, on the lens of the visual assembly 2, and the air spraying assembly 21 sprays air on the lens of the visual assembly 2 to blow away the liquid and impurities.
