Abstract
The invention provides a device and method for detecting weft breakage and weft completion of a circular knitting machine on the basis of an image technology. The method comprises the steps that an image of a shuttling pipe of the circular knitting machine in a normal working state is acquired through a CCD camera, and is sent to a computer to be processed, and the processed image is stored to form a matching model; the CCD camera acquires images of the shuttling pipe of the circular knitting machine in a continuous operation state in real time, the images are sent to the computer to be processed and are stored, the processed real-time images and the matching model stored in the first step are compared and analyzed; the comparison results are analyzed, whether weft breakage and weft completion of the circular knitting machine happen or not is judged, if the shuttling pipe does not conduct rotational movement from a certain moment, weft breakage can be determined, and if the color of the shuttling pipe is the image color of the exposing shuttling pipe instead of the color of yarn, weft completion can be determined. The device and method for detecting weft breakage and weft completion of the circular knitting machine on the basis of the image technology provide a quite reliable device and method for detection of circular knitting machine weft breakage and weft completion of conductive fibers such as carbon fibers in the textile industry.
Description
Technical field
The present invention relates to field of textile machinery, particularly a kind of based on image technique, can be used for detecting the conductive fiber woven circular loom staplings such as carbon fiber and complete latitude checkout gear and method.
Background technology
Current existing technology is the detection of using additional calutron to realize circular loom staplings and complete latitude.Adopt electromagnetic induction operation principle, when circular loom normal operation is weaved, in weft yarn traction shuttle pipe racks motion detection device, the rotor turns of transmitter produces pulse signal, and be sent to receiver by electromagnetic wave, when staplings, weft yarn can not draw shuttle pipe racks and move rotor turns, so transmitter can not produce pulse signal, distinguish whether staplings according to whether producing pulse signal.When complete latitude, the conducting probe that exposed shuttle Guan Huiyu relies on spring pressure to contact with thread friction always contacts, and has caused latitude testing loop conducting, thus has detected latitude state.
In actual applications, each parts of this electromagnetic detection are all subject to the impact of many external factor, and stability is not high, detects easy misalignment.In device, element is limited for service life, often needs to change, and fatigue and the damage of element all will affect checkout gear sensitivity, accuracy of detection be reduced, work efficiency drop, not easily ensure product quality.
Especially, when the contour performance conductive fiber of woven carbon fibre, due to fiber conduction itself, this detection method lost efficacy.Carbon fiber is very easy to fluffing, and this method by the complete latitude of contact detection can not use, and easily scrapes hair and scratch fiber.And carbon fiber weaving time space conduction dust is many, is easy to cause original poorly sealed electromagnetic detection to cause short-circuit fire, and the problem such as mistaking signal, and Carbon fiber dust also has very major injury to workman.
Summary of the invention
The technical problem to be solved in the present invention is the defect overcoming above-mentioned prior art, provides a kind of and can be used for the conductive fibers such as carbon fiber woven circular loom staplings and complete latitude checkout gear and method based on image technique.
In order to solve the problems of the technologies described above, the invention provides a kind of based on the circular loom staplings of image technique and the checkout gear of complete latitude, it is characterized in that, comprise at least one and be located at CCD camera above circular weaving machine shuttle pipe, described CCD camera connects the computer being used for image processing and analysis.
Present invention also offers and a kind ofly to it is characterized in that based on the circular loom staplings of image technique and the detection method of complete latitude, adopt above-mentioned based on the circular loom staplings of image technique and the checkout gear of complete latitude, concrete steps comprise:
The first step: obtain the image of shuttle pipe under circular loom normal operating conditions by CCD camera and send computer disposal, and being Matching Model by the Image Saving after process;
Second step: under the continuous operating condition of CCD camera Real-time Obtaining circular loom shuttle pipe image and send computer disposal and preserve, the realtime graphic after process and the first step Matching Model of preserving are analyzed;
3rd step: analyze comparing result, judges loom whether staplings and complete latitude, if from a certain moment, shuttle pipe does not rotate, then can judge staplings, if from a certain moment, the color of shuttle pipe is not yarn color, but expose the color of image of shuttle pipe, then can judge latitude.
The present invention utilizes image collecting device and image processing techniques to detect the circular loom staplings of the conductive fibers such as carbon fiber and complete latitude by cordless.Gathered the duty image of circular weaving machine shuttle pipe by CCD camera captured in real-time, obtained the image information of shuttle pipe by image processing techniques, and then judge staplings and complete latitude by doing to mate with the iconic model of shuttle pipe under circular loom normal operating conditions.When circular loom normally works, weft yarn drives shuttle pipe to rotate, if from a certain moment, the image of coupling Real-time Collection judges that shuttle pipe does not rotate, then can judge staplings.Before complete latitude, the result of carrying out color-match to the shuttle tube-surface of captured image is the color of yarn, if from a certain moment, color matching results is the color that after exposing shuttle pipe, yarn runs low, and illustrates that now shuttle pipe exposes, and can judge latitude.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention is based on non-contact image detection technique; Only need detect the motion state of shuttle pipe and yarn cylinder surface color image conditions to judge staplings and complete latitude.Adopt image technique checkout gear of the present invention and method, can the circular loom staplings of conductive fiber and the detections of complete latitude such as carbon fiber be carried out, the problem that before solving, device cannot detect.Owing to have employed high-precision image processing techniques, thus have accuracy of detection high, antijamming capability is strong, and stability is high, simple and reasonable, and performance safety is reliable, long service life and be convenient to the advantages such as installation and maintenance.Effective reduction Carbon fiber dust, to the harm of workers ' health, improves operating efficiency, ensure that fabric quality.Also the structure of original shuttle can be simplified.Thus overcome the deficiencies in the prior art, for the circular loom staplings of conductive fiber such as textile industry carbon fiber and the detection of complete latitude provide the very reliable apparatus and method of one.
