Abstract
The invention discloses a deformation detector for knitting elements of a warp knitting machine. The deformation detector for the knitting elements of the warp knitting machine comprises an image acquisition device, an image processing device, a storage device and an auxiliary device. Depending on an advanced image processing technology, the detector assists warp knitting machine debugging personnel to efficiently and conveniently detect the deformation of the knitting elements of the warp knitting machine, and inconvenience and errors caused by manual measurement are reduced as much as possible. The auxiliary device comprises an illumination system, an automatic telescopic frame, a guide rail, an infrared generator and a sounding member. In detection, yarn guiding combs enter a needle plane in sequence by means of manual positioning, the detector stretches to the front end of a device to be measured and moves from a machine head to a machine tail along the guide rail; collected images are input to the image processing device; an edge detection algorithm is used to extract edges; main knitting elements of the warp knitting machine are identified; and whether the knitting elements deform is judged. The detector stops moving when a deformed element is detected, the infrared generator emits rays to the deformed element, and at the same time, the sounding device makes a sound to prompt workers to carry out checking. After a fault is removed, the detector continues to move along the guide rail. The detector can be connected with a computer through a USB interface so as to send data to the computer.
Description
Technical field
The present invention relates to a kind of detection system for the distortion of tricot machine loop-forming element, belong to fabric detection field, be specifically related to image collecting device, image processing apparatus, storage device and servicing unit.
Background technology
In textile manufacturing, because tricot machine is in working at high speed state for a long time, can there is distortion in various degree in its loop-forming element, as knitting needle deflection, bend, fracture.The microdeformation of loop-forming element can produce considerable influence to the mode of appearance of fabric.The deformation detection of tricot machine loop-forming element is not also effectively solved at present, in Realism Design production, loop-forming element deformation observes laggard row relax by staff experienced in factory often, due to the arrangement of parts volume little and loop-forming element closely, the result drawn like this, because of error considerable influence product quality, is unfavorable for the raising of production efficiency.
Detection method can be manual detection and instrument detects two kinds.This traditional detection method of manual detection requires that staff has abundant working experience and rigorous working attitude.And instrument detection has the advantages such as automaticity is high, measuring speed is fast, precision is high, be more and more subject to people's attention, particularly under the high speed development of existing science and technology, the measuring accuracy that instrument detects and stability obtain further raising.
In instrument testing process, the process of image needs to use edge detecting technology.Image border is image is substantially the most also one of most important feature, and the rim detection of image is content important in computer vision and image procossing.Edge extracting method accurately and reliably, plays vital effect to the overall performance of these systems, and therefore edge extracting becomes one of heat subject paid close attention to the most when researchist carries out image characteristic analysis research.The object of edge extracting is exactly find the edge belonging to interested objective contour, and at present, the method for Image Edge-Detection is a lot, mainly contains RobertS operator, Sobel operator, Prewitt operator, LOG operator, Canny operator, wavelet analysis method etc.
For understanding tricot machine loop-forming element deformation and process problem, the invention provides the detection system of a set of tricot machine loop-forming element distortion, image collecting device, image processing apparatus, storage device and servicing unit is related in invention, be intended to image processing techniques is applied to tricot machine loop-forming element deformation detection aspect, thus improve speed and the accuracy of tricot machine parts deformation detection.
Summary of the invention
The object of the invention is to by a kind of tricot machine loop-forming element deformation detection instrument, it comprises image collecting device, image processing apparatus, storage device and servicing unit, the product quality problem that the distortion solving loop-forming element on tricot machine causes, auxiliary tricot machine machine commissioning staff efficiently detects the distortion of tricot machine loop-forming element easily, the inconvenience brought when reducing manual measurement as far as possible and error, ensure product quality, enhance productivity.For reaching this object, the present invention by the following technical solutions:
Described tricot machine loop-forming element image acquisition system uses CCD camera.Image collecting device can obtain the image of tricot machine loop-forming element.After instrument brings into operation, automatic expansion bracket can according to the parameter arranged, and automatically regulate the distance of detector and measured device, CCD camera automatic focusing, detector runs to tail along guide rail from head.During image capturing system work, the illumination system in servicing unit is always in running order.
Described image processing apparatus can read in the real-time loop-forming element image that image acquisition device arrives, the edge of first step application edge detection algorithm identification tricot machine loop-forming element, then uses appropriate algorithm to judge whether loop-forming element is out of shape further.
Described image processing apparatus is connected with storage device, for being stored by the data be disposed input storage device;
Described instrument is connected with computer by USB interface, and data are sent to computer.Corresponding data can be read on computers and operate accordingly.

Embodiment
According to Fig. 1, the present invention will be further described below
The present invention discloses a kind of tricot machine loop-forming element deformation detection instrument, comprises image collecting device, image processing apparatus, storage device and servicing unit.This pick-up unit relies on advanced image processing techniques, and auxiliary tricot machine machine commissioning staff efficiently detects the distortion of tricot machine loop-forming element easily, the inconvenience brought when reducing manual measurement as far as possible and error.Servicing unit comprises illumination system, automatic expansion bracket, guide rail, infrared emittance and microphone device.
For tricot machine 4 sley bar, the workflow of tricot machine loop-forming element deformation detection instrument is understood.According to the position of sley bar on machine, number consecutively is GB1, GB2, GB3, GB4 from right to left.
Before detector runs, artificial location makes guide comb and enters pin plane successively, the deformation range of setting tricot machine loop-forming element.After detector brings into operation, automatic expansion bracket can according to the parameter arranged, and regulate the distance of detector and measured device, detector reaches the front end of detected device, and instrument and measured device relative position are shown in accompanying drawing 2.CCD camera automatic focusing, detector runs to tail along guide rail from head.During image capturing system work, the illumination system in servicing unit is always in running order.Image processing apparatus reads in the real-time loop-forming element image that image acquisition device arrives, the edge of first step application edge detection algorithm identification tricot machine loop-forming element, algorithm is used to judge the edge variation of loop-forming element more further, contrast with the deformation range of the tricot machine loop-forming element of setting, judge whether distortion.As do not exceeded deformation range, detector continues to run along guide rail; As exceeded deformation range, machine is out of service immediately, and launches infrared-ray mark deformed region, and microphone device is sounded to remind and manually checked.After fixing a breakdown, detector continues to move ahead along guide rail.This instrument is connected with computer by USB interface, and data are sent to computer.
