AI Technical Summary
During the warping process, it is difficult to detect the yarn break in time, resulting in the unqualified whole textile.
A warp disconnection detection structure is designed, using the servo motor and the camera to work together, and the number of warp yarns is identified through the color difference comparison of the control panel. When a break is found, the warp is controlled to shut down and retreat to the disconnection position.
High-precision wire break detection is achieved, which avoids textile failure caused by yarn breakage, and can accurately locate the wire breaking position.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of warping machines, in particular to a wire breakage detection structure for warping machines. Background Art
[0002] Warping is the process of winding a certain number of warp yarns in parallel on a warp beam or weaving beam according to specified length and width.
[0003] The warping machine is a device that completes the above process. During the warping process, many strands of yarn are processed simultaneously. If the yarn breaks, it is difficult to detect it in time. If the machine is not stopped for wiring, the entire textile will be unqualified. Utility Model Content
[0004] In order to solve the above technical deficiencies, the utility model provides a warping machine wire breakage detection structure, which can detect the wire breakage of yarn.
[0005] The utility model discloses a wire breakage detection structure for a warping machine, comprising a warping machine frame, mounting seats are arranged on the upper ends of both sides of the warping machine frame, a lead screw is arranged horizontally between the mounting seats on both sides, both ends of the lead screw are rotatably mounted on the mounting seat, parallel and equidistant warp yarns are transported below the lead screw, the lead screw and the warp yarns are perpendicular to each other, a servo motor connected to the lead screw transmission is arranged on the mounting seat, a lead screw nut is arranged on the lead screw, a guide rod parallel to the lead screw is arranged on one side of the lead screw, both ends of the guide rod are fixedly connected to the mounting seat, a slider is slidably arranged on the guide rod, the slider is fixedly connected to the lead screw nut, a camera with a lens facing the warp yarn is arranged on the lower side of the slider, a comparison plate is arranged horizontally on the lower side of the warp yarn, both ends of the comparison plate are fixed to the warping machine frame, positioning protrusions are arranged at equidistant intervals on the upper end surface of the comparison plate, the same number of warp yarns are contained in adjacent positioning protrusions, and the camera and the servo motor are electrically connected to a warping machine controller.
[0006] The principle of the above technical solution is that the warping machine controller coordinates the rotation of the servo motor and the shooting timing of the camera so that each time a photo is taken, two adjacent positioning protrusions and the warp yarns between the two adjacent positioning protrusions are captured into the picture, and the captured picture is input into the warping machine controller. The function of the reference plate is to produce an obvious color difference contrast through the different colors of the reference plate and the warp yarns. The warping machine controller identifies the number of warp yarns between the two positioning protrusions based on the color difference contrast between the warp yarns and the reference plate. When the warp yarn breaks and the number is incorrect, the warping machine controller controls the warping machine to stop and controls the servo motor to make the camera move back to the position where the warp yarn breaks.
[0007] In order to ensure that it is bright enough when taking pictures, fill lights are installed on the sliders on both sides of the camera.
[0008] The utility model provides a warping machine wire breakage detection structure, which has the beneficial effects of being able to detect warp wire breakage with high detection accuracy and not prone to missed detection, and being able to stop the camera at the wire breakage position after detecting the wire breakage.
