When the circular knitting machine online quality monitoring device is adopted, the quality of the products can be inspected ceaselessly during the operation of the equipment, the flaws on the products can be judged, the type and the position of the flaw can be pointed out.
Description
Technical field
The utility model relates to the online quality monitoring device of a kind of circular knitter.The quality that is used for online auto monitoring circular knitter knit product.Belong to technical field of textile machine.
Background technology
At knitting industry, the quality restriction of product has expended the great amount of manpower resource always.Its working contents of production spinner of one line of textile enterprise, topmost one is exactly going on patrol back and forth in the production scene of not stopping, to prevent the generation of substandard products.Because each staff's limit of power is limited, is unable to control or manage too many board, therefore, a line spinner of textile mills is not only large contingent, and is to be celebrated greatly with work under bad environment, labour intensity always.However, skilled again textile worker still can produce the weaving substandard products of some.In addition, textile enterprise also has the huge product quality inspection personnel of quantity, carries out quality restriction at raw material, semi-manufacture, this several links of finished product specially.Be that workload is huge equally, labour intensity is big, and, can not guarantee not take place the situation of omission.
Summary of the invention
Content of the present utility model is to overcome all deficiencies in the above knitting production run, and a kind of online quality monitoring device of circular knitter that carries out the knit goods on-line monitoring based on computer pattern recognition principle is provided.
The purpose of this utility model is achieved in that the online quality monitoring device of a kind of circular knitter based on computer pattern recognition principle, described device is to adopt a kind of digital image acquisition device, this digital image acquisition device adopts line array CCD or cmos sensor, or employing area array CCD or cmos sensor, described digital image acquisition device is fixed on the board inboard, below of circular knitter, described digital image acquisition device camera lens is towards the circular cloth tube of circular knitter, digital image acquisition device camera lens is apart from the cloth cover certain distance (distance of concrete distance of circular cloth tube, adjust to a position the most effective according to the focal length of the camera lens on the digital image acquisition device), this digital image acquisition device links to each other with the site disposal main frame
Be provided with standard cloth specimen storehouse and blemishes storehouse in the described site disposal main frame,
Described standard cloth specimen storehouse and blemishes storehouse are in advance at the sampling of taking pictures of standard cloth specimen and cloth blemishes, and are organized into the storehouse later on through digitized processing, and storage is advanced in the site disposal main frame,
Described site disposal main frame band LCDs and keyboard, and possess external communication interface and external memory interface.
Adopt the utility model device; can be in equipment running process; the quality of the inspection product that does not stop all the time; judge the blemishes of product; produce in case find blemishes, send all kinds of suitable alerting signal notifying operation personnel immediately, can pass through the shutdown bus interface of Weaving device simultaneously as required automatically; allow equipment downtime, and point out blemishes type and blemishes occurrence positions.Thereby substitute the tour observation that people-to-people contacts a large amount of in this production run are hurried back and forth and carried out with this.Greatly improve labor productivity, reduce the generation of substandard products, reduce labour's use amount.
Description of drawings
Fig. 1 is that the utility model is based on the online quality monitoring device of the circular knitter of computer pattern recognition principle synoptic diagram.
Fig. 2 is the utility model perching theory diagram.
Among the figure: circular cloth tube 1, digital image acquisition device 2, site disposal main frame 3.
Embodiment
The online quality monitoring device of the circular knitter that the utility model relates to based on computer pattern recognition principle, be to adopt a kind of digital image acquisition device, this digital image acquisition device adopts line array CCD or cmos sensor, or employing area array CCD or cmos sensor, described digital image acquisition device is fixed on the board inboard, below of circular knitter, be fixed sturcture, do not produce motion all the time.Described digital image acquisition device camera lens is towards the circular cloth tube of circular knitter, and digital image acquisition device camera lens is apart from the cloth cover 2～5cm of circular cloth tube, as Fig. 1.Continuous rotation according to circular cloth tube in producing, this digital image acquisition device is according to the frequency of taking pictures in the unit interval of setting (be set at per second such as the linear array digital image acquisition device of 2000 pixels and take pictures 500), carry out continual taking pictures at the cloth cover in the motion, linear array of being gathered or face battle array digital pictures pass to the site disposal main frame in real time, be provided with standard cloth specimen storehouse and blemishes storehouse in the described site disposal main frame, according to the computer picture recognition principle, carry out the identification of cloth cover blemishes image comparison and handle, judge (the cloth specimen picture and the blemishes storehouse in the on-the-spot main frame that photograph do not stop to compare processing all the time) thereby carry out the textile blemishes.In case judge blemishes, then can send alerting signal immediately even allow board shut down, and, report out the type of the blemishes on the cloth according to the blemishes type of coincideing in the site disposal main frame blemishes storehouse; Take pictures position and board travelling speed according to nearest digital image acquisition device calculate the particular location that blemishes take place.Described standard cloth specimen storehouse and blemishes storehouse are in advance at the sampling of taking pictures of standard cloth specimen and cloth blemishes, and are organized into the storehouse later on through digitized processing, and storage is advanced in the site disposal main frame.
As Fig. 2, described site disposal main frame can be the computing machine of various structures, IO interface such as band LCDs, keyboard, and possesses external communication interface, for this device of manufacturing enterprise's remote control, the embedded program of remote update or upgrade the blemishes storehouse (by the external communication interface of site disposal main frame, the long-range content that needs can be upgraded, by communication modes such as network directly replenish or the embedded program that substitutes on-the-spot main frame in the blemishes storehouse).Described site disposal main frame also is equipped with external memory storage (as: USB flash disk) interface, the renewal work that manufacturing enterprise also can manually be correlated with at the scene.The site disposal main frame is as a front-end processing terminal, and is small-sized, can be applied in the rugged surroundings of production scene.Can be installed on all kinds of circular knitters, concrete mounting means is: any one does not influence the board top production, is convenient to operating personnel's observation and the occasion of operating.
The monitoring device that institute's utility model method is adopted is divided into following three parts: digital image acquisition device, site disposal main frame and peripheral mechanical hook-up.Peripheral mechanical hook-up is made separately according to the difference of all kinds of circular knitters, its objective is to be used to install and fix the digital image acquisition device and to install and fix the site disposal main frame.Make the work that these devices can be effective and stable.This device can be installed in above all kinds of circular knitter tools.
