Description
Technical field
The present invention relates to a kind of Computerized flat knitting machine control system and control method.
Background technology
The fast development of hosiery trade is more and more higher to the requirement of knitting process equipment.Most equipment also needs a large amount of manpowers, and every machine all needs a skilled workman to carry out operational administrative, and production efficiency is low, and the quality of product is directly relevant to workman's skilled operation degree.The technologist works out generation plate-making program according to oneself intention or customer demand to flower type image, but this process is consuming time longer, generally needs a few hours or a couple of days to programme and completes, and causes the delivery cycle long, and efficient is lower.Simultaneously, the compatibility of this program code is very low, also need design different plate-making programs for the Computerized flat knitting machine of different brands, has increased programming personnel's labour intensity, has also increased production cost.
At present, Computerized flat knitting machine is mostly by the magnet control needle selection, and the lifting by electromagnet comes needle selection.The magnetic-holding electric magnet that uses on Computerized flat knitting machine is when electromagnet during at attracting state, because magnetic core gos deep into the electromagnetic actuation coil inside, magnetic flux increases to some extent, when electromagnet is in open mode, because magnetic core leaves the electromagnetic actuation coiler part, magnetic flux reduces to some extent.But use the parts of electromagnet action because the space is narrower and small on general Computerized flat knitting machine, environment for use is abominable, therefore can't the installation site checkout gear.Cause because of the problem of mechanism driving problem or electromagnet itself and be failure to actuate or to cross action very general, this is the common fault that all exists on all Computerized flat knitting machines at present.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of Computerized flat knitting machine control system and control method are provided.
The Computerized flat knitting machine control system comprises flower type in kind, imager, image processor, data conversion module, master controller, stand alone type braiding controller, data acquisition unit and braiding Executive Module; Flower type in kind, imager, image processor, master controller, stand alone type braiding controller, braiding Executive Module are connected in turn, braiding Executive Module, data acquisition unit, stand alone type braiding controller, master controller are connected in turn, data conversion module is connected with image processor, the braiding Executive Module comprises electromagnet, magnetic flux detection sensor and braiding executing agency, and electromagnet comprises magnetic core and electromagnet coil; Braiding executing agency is positioned at an end of the magnetic core action of electromagnet, and the side of electromagnet coil is equipped with magnetic flux detection sensor, and the output of magnetic flux detection sensor is connected with the input of data acquisition unit.
The step of the control method of Computerized flat knitting machine control system is as follows:
1) material object flower type is placed in imager, opens the imager power switch, scanning flower in kind type generates entity appearance contour images file, and entity appearance contour images file deposits in image processor automatically;
2) compiler of image processor input entity appearance contour images file or the data conversion module conversion data of coming by compiling automatic generation plate-making style figure code, and deposit in master controller;
3) master controller identification plate-making style figure code, and figure code data signal is transferred to stand alone type braiding controller;
4) free-standing braiding controller reads figure code data signal, controls the magnetic core action of electromagnet, and drive weaves executing agency and carries out braid movement, and magnetic flux detection sensor detects the variation of the magnetic flux in electromagnet magnetic core course of action in real time simultaneously;
5) magnetic flux detection sensor gathers flux information, and passes the signal to data acquisition unit, and data acquisition unit carries out the transformational analysis of data to be processed, and data are outputed to stand alone type braiding controller;
6) stand alone type braiding controller compares the actual magnetic flux that records and theoretical magnetic flux, judge whether correct operation of magnetic core, if magnetic core correct operation, weave executing agency and continue the next round braiding, if the magnetic core incorrect operation, stand alone type braiding controller sends action pulse again, and again judge, if magnetic core still without response, stops weaving and feeding back to master controller, the caution of reporting to the police;
7) repeating step 4)～process of step 6), until complete the braiding of flower type in kind.
Use the present invention, directly use imager that material object flower type is scanned, automatically generate entity appearance contour images file, and compile by image processor, improved production efficiency, shortened the time of delivery.The input of data conversion module of the present invention can connect the forme-producing system of other main flows on present market simultaneously, and its data are carried out format conversion, be transferred to image processor, be compiled into the plate-making style figure code of coupling Computerized flat knitting machine by the compiler of image processor.The compiler of image processor possesses powerful compatible performance, only needs programmer's operation of only understanding a kind of forme-producing system, has reduced programming personnel's quantity and specification requirement, has reduced the training cost to various plate-making personnel and operating personnel.The present invention has simultaneously carried out the operating position detection to the part that relates to the electromagnet use, utilize electromagnet in adhesive and the variation of the magnetic flux when opening, judge the operating position of electromagnet by magnetic flux detection sensor, guaranteed the stability of machine, improved the quality of product.
