Technical Field

[0001] The utility model relates to the technical field of warp knitting machines, in particular to a yarn storage and winding detection device for warp knitting machines. Background Art

[0002] Warp knitting machines are used to produce fabrics. When producing woven fabrics, a loop forming process is carried out in the knitting area, in which the yarns of the warp threads being fed in parallel are connected to each other by forming loops, and the surface fabric produced in this way is drawn off via a fabric take-up device. The fabric take-up device here has at least one or more rollers, via which the woven fabric is guided.

[0003] During the weaving process, the warp knitting machine needs to go through the process of yarn storage and yarn feeding.

[0031] like Figures 1 to 4 As shown: A yarn storage and winding detection device for a warp knitting machine, comprising:

[0032] A yarn storage component 1, the yarn storage component 1 comprises a roller 11, and the yarn passes through the roller 11 and enters the fabric;

[0033] Industrial camera 2, which is arranged at the backlight of roller 11, and takes a picture of roller 11 to identify the winding wire;

[0034] The mounting bracket 3 is used to fix the industrial camera 2 .

[0035] Roller 11 is the passage for yarn to enter fabric. Yarn passes over roller 11 and enters fabric to form coils. Industrial camera 2 is set at the backlight of roller 11. This position is conducive to taking images of roller 11. The camera will take images of roller 11 regularly or continuously. When the fabric is running, the camera will take images of roller 11 and perform winding identification through image processing algorithms. These algorithms can identify whether the yarn enters the fabric correctly from roller 11 and whether winding occurs. The mounting bracket 3 is used to fix the industrial camera 2 in an appropriate position to ensure that the camera can accurately align with roller 11 and take clear images. The operator can make adjustments and processing based on the image data provided by the camera to ensure the normal operation of the warp knitting machine and the quality of the fabric.

[0036] In this embodiment, the mounting bracket 3 is disposed at the bottom of the roller 11 , and the industrial camera 2 takes pictures facing the bottom of the roller 11 .

[0037] The camera takes pictures facing the bottom of the roller roller 11, which can provide more intuitive and clearer images, which is conducive to the accurate identification and judgment of the wire winding situation. The camera arranged at the bottom of the roller roller 11 can reduce light interference and take clearer and more accurate images, which is conducive to the accurate detection of the wire winding situation. It is a preferred solution to arrange the mounting bracket 3 at the bottom of the roller roller 11 and the industrial camera 2 takes pictures facing the bottom of the roller roller 11, which can better realize the function of the wire winding detection device and improve the production efficiency and product quality of the warp knitting machine.

[0038] Alternatively, the mounting bracket 3 is arranged on the side of the bottom of the roller roller 11 , and the industrial camera 2 takes a picture of the side of the bottom of the roller roller 11 .

[0039] The angle at which the camera shoots the bottom side can reduce the impact of light interference and other environmental factors on image quality, which is conducive to obtaining clear and accurate image data. The mounting bracket 3 arranged on the side is easier to adjust the angle and position to ensure that the camera can be optimally aligned with the bottom side of the roller roller 11 and obtain the best shooting effect. The mounting bracket 3 is arranged on the bottom side of the roller roller 11, and the industrial camera 2 takes pictures of the bottom side of the roller roller 11. This is also a preferred solution, which can better realize the function of the wire winding detection device and improve the production efficiency and product quality of the warp knitting machine.

[0040] As a preferred embodiment of the above, the mounting bracket 3 includes:

[0041] A tube clamp 31, which is arranged on the frame of the warp knitting machine;

[0042] A first connecting rod 32, the first connecting rod 32 is disposed on the pipe clamp 31 and is horizontally arranged;

[0043] A universal cross connector 33, one end of which is disposed on the first connecting rod 32;

[0044] A second connecting rod 34, which is disposed at the other end of the universal cross connecting member 33, and the industrial camera 2 is disposed on the second connecting rod 34;

[0045] The two ends of the universal cross connection member 33 can rotate relative to each other.

[0046] By designing the mounting bracket 3 in this way, the height of the position of the industrial camera 2 can be adjusted and flexibly adjusted, ensuring that the camera can be optimally aligned with the bottom side of the roller 11, thereby improving the accuracy and efficiency of wire winding detection.

[0047] When the first connecting rod 32 is disposed on the pipe clamp 31 , the first connecting rod 32 can be adjusted along the length extension direction of the first connecting rod 32 .

[0048] The first connecting rod 32 can be adjusted along its length. This means that during the installation process, the operator can adjust the length of the first connecting rod 32 according to specific needs to adapt to installation requirements at different positions and angles. This adjustability makes the installation process more flexible and can more easily achieve the best position installation of the camera.

[0049] Alternatively, both ends of the universal cross connector 33 are respectively sleeved on the first connecting rod 32 and the second connecting rod 34 , and can rotate relative to the first connecting rod 32 and the second connecting rod 34 .

[0050] By respectively sleeve-mounting the two ends of the universal cross connector 33 on the first connecting rod 32 and the second connecting rod 34, the connector can be rotated relative to the two connecting rods. In this way, the industrial camera 2 can achieve a wider range of rotations in the horizontal and vertical directions, thereby more flexibly adjusting the angle to best capture the desired image, further improving the flexibility and adjustment capability of the mounting bracket 3, and providing more options and possibilities for installing the industrial camera 2 at the best position.

[0051] In addition, a second universal cross connector 33 is fixedly provided on the industrial camera 2 , and two ends of the second universal cross connector 33 are respectively connected to the industrial camera 2 and the second connecting rod 34 , and the two ends of the second universal cross connector 33 can rotate with each other.

[0052] By providing a second universal cross connection member 35 on the industrial camera 2 and connecting the industrial camera 2 and the second connection rod 34, the installation position and angle of the camera can be more widely adjusted. The two ends of the second universal cross connection member 35 can rotate relative to each other, which further increases the adjustment range of the camera, allowing more flexible adjustment in both horizontal and vertical directions.

[0053] As a preference of the above embodiment, the second universal cross connector 35 is sleeved on the second connecting rod 34 and can rotate relative to the second connecting rod 34 .

[0054] It is a preferred design to sleeve the second universal cross connector 35 on the second connecting rod 34 and enable it to rotate relative to the second connecting rod 34. This design provides more adjustment options and flexibility, can meet different installation requirements, and improve the reliability and efficiency of the wire winding detection device.

The above embodiments and the description are only for explaining the principle of the present invention.
