Summary of the invention
Content of the present utility model is to overcome all deficiencies in the above spinning production run, provides a kind of based on the spin device of the online quality monitoring of semi-manufacture that comb and parallel cotton fibers prior to spinning in the production run, drafting, this several process procedure of rove produced of computer pattern recognition principle.
The purpose of this utility model is achieved in that the online quality monitoring device of a kind of spinning products 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 comb and parallel cotton fibers prior to spinning in the spinning production run, drafting, the discharging opening place of the related machinery of these a few road technologies of rove, described digital image acquisition device camera lens is towards comb and parallel cotton fibers prior to spinning, drafting, the rove semi-manufacture, digital image acquisition device camera lens is apart from the described semi-manufacture certain distance (distance of concrete distance, 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 comb and parallel cotton fibers prior to spinning, drafting, rove semi-finished product standard storehouse and blemishes storehouse in the described site disposal main frame,
Described java standard library and blemishes storehouse are in advance at the sampling of taking pictures of standard semi-manufacture and blemishes semi-manufacture, 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 for the utility model adopted based on comb and parallel cotton fibers prior to spinning in the spinning process of computer pattern recognition principle, drafting, the online quality monitoring device of rove semi-manufacture synoptic diagram.
Fig. 2 detects theory diagram for the utility model.
Among the figure: comb and parallel cotton fibers prior to spinning, drafting, rove semi-manufacture 1, digital image acquisition device 2, site disposal main frame 3.
Embodiment
Comb and parallel cotton fibers prior to spinning during the spinning based on computer pattern recognition principle that the utility model relates to is produced, drafting, the online quality monitoring device of rove semi-manufacture, be to adopt a kind of digital image acquisition device 2, this digital image acquisition device 2 adopts line array CCD or cmos sensor, or employing area array CCD or cmos sensor, described digital image acquisition device 2 is fixed on the discharging opening place of comb and parallel cotton fibers prior to spinning in the spinning production run, drafting, the related machinery of these a few road technologies of rove, be fixed sturcture, do not produce motion all the time.Described digital image acquisition device 2 camera lenses are towards comb and parallel cotton fibers prior to spinning, drafting, rove semi-manufacture 1, digital image acquisition device 2 camera lenses are apart from comb and parallel cotton fibers prior to spinning, drafting, the rove semi-manufacture 1 certain distance (distance of concrete distance, adjust to a position the most effective according to the focal length of the camera lens on the digital image acquisition device 2), as Fig. 1.Making the semi-manufacture behind comb and parallel cotton fibers prior to spinning, drafting, the rove is to pass through below the camera lens of digital image acquisition device 2 all the time, and digital image acquisition device 2 can be scanned these semi-manufacture all the time.According to half-finished continuous output described in the production, this digital image acquisition device 2 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 semi-manufacture in the motion, linear array of being gathered or face battle array digital pictures pass to site disposal main frame 3 in real time, be provided with java standard library and blemishes storehouse in the described site disposal main frame 3, according to the computer picture recognition principle, carry out described semi-manufacture blemishes image comparison identification and handle, judge (the semi-manufacture 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 described semi-manufacture according to the blemishes type of coincideing in the site disposal main frame blemishes storehouse; According to the take pictures position and the board travelling speed of nearest digital image acquisition device, calculate and point out the particular location that blemishes take place.Described java standard library and blemishes storehouse are in advance at the sampling of taking pictures of described standard semi-manufacture and blemishes semi-manufacture, and are organized into the storehouse later on through digitized processing, and storage is advanced in the site disposal main frame 3.
