Fig. 2 is method flow diagram of the present utility model;
Wherein, 1 is warp knitting machine main body, and 2 is knitting needle, and 3 is high-speed camera unit, and 4 for storing control unit, and 5 is alarm unit, and 6 is sley point.
Detailed description of the invention
Below in conjunction with accompanying drawing, describe the technical solution of the utility model in detail.
As shown in Figure 1, the warp knitting machine with burn out detection function of the present utility model, comprises the warp knitting machine main body 1 with sley point 6, also comprises the high-speed camera unit 3, storage control unit 4 and the alarm unit 5 that connect successively; Described high-speed camera unit 3 is for gathering the figure warp thread picture at sley point 6 place and knitting needle 2 (comprising groove pin, latch needles and crochet hook) place, and give storage control unit 4 by figure warp thread Image relaying, therefore preferably high-speed camera unit 3 can be set up in sley point 6 and the top of knitting needle 2, oblique side can be arranged in addition; Described figure warp thread picture comprises the figure warp thread picture of standard and figure warp thread picture to be detected; Store the image that control unit 4 gathers for receiving high-speed camera unit 3, stored and processed, and send alarm signal when needs to alarm unit 5, alarm unit is for receiving the alarm signal storing control unit and send, and carrying out corresponding operating, corresponding operating comprises the operation of reporting to the police or not reporting to the police.
Described knitting needle 2 comprises groove pin, latch needles or crochet hook, and warp knitting machine has sley point 6 and knitting needle 2 simultaneously, and sley point draws yarn, and knitting needle, from sley point hook yarn, is exactly mainly during this time take yarn.
In order to warp knitting machine can be stopped in time; reduce loss, this device also comprises the autostop driver element be connected with storage control unit, when finding that there is broken string; store control unit and send stopping signal to autostop driver element, autostop driver element controls warp knitting machine and stops.
The collection speed image of high-speed camera unit is 100 ~ 1000 frames/second, so designs, and makes it can with very high frequency record dynamic image, can Real-time Collection figure warp thread picture to be detected.High-speed camera unit can complete quick, multiple repairing weld to high-speed target in a short period of time, when showing with conventional speeds, the change procedure of institute's record object just clear, be presented on us at the moment lentamente; It has the outstanding advantages such as real-time target is caught, image fast recording, instant playback, image are visual and clear.Based on cost and realize effect consider, described high-speed camera unit is that it has high resolution ratio based on CMOS chip high speed imaging system, and do not need traditional chemical photographic film, cost is low, can reproduce the process of high-speed motion, can be widely used in high-speed camera field.
In order to improve the dynamics of alarm, audible-visual annunciator can be adopted as alarm unit, being reported to the police by vision and the sense of hearing two aspect.
As shown in Figure 2, warp knitting machine wire break detection method of the present utility model, comprises the following steps:
1. high-speed camera unit gathers the figure warp thread picture of the standard at sley point place and knitting needle place, and sends to and store control unit and store, the image of the yarn that namely the figure warp thread picture of standard does not break;
Can before warp knitting machine runs the figure warp thread picture of collection standard, also can at the figure warp thread picture opening collection standard in the certain hour (a few second) after warp knitting machine, because a few minutes carry out preheating to tens minutes inner machines after unlatching warp knitting machine, can not run; Or after opening warp knitting machine a few minutes to dozens of minutes, do not have yarn broken string situation, therefore can gather the figure warp thread picture of standard at this moment.
2., along with the operation of yarn, the collection of high-speed camera unit runs to the figure warp thread picture to be detected at sley point place and knitting needle place, and sends to storage control unit;
3. store control unit the figure warp thread picture of figure warp thread picture to be detected and standard is carried out analysis to contrast, whether both judgements image is identical, if so, then step B is returned, if not, then again gather the figure warp thread picture to be detected at sley point place and knitting needle place, and send to storage control unit, store control unit and the figure warp thread picture of figure warp thread picture to be detected and standard is carried out analysiss contrast, if the two image still difference, then enter step D, otherwise return step B.
In order to strengthen accuracy rate and reliability, the figure warp thread picture that this method adopts repeatedly continuous acquisition to be detected, so that when determining that the image of multi collect is all different from the figure warp thread picture of standard, just there is broken string.The figure warp thread picture of figure warp thread picture to be detected and standard is carried out analyzing the technology contrasted and can apply existing photo or image comparison technology.
4. store control unit and send alarm signal to alarm unit, alarm unit is reported to the police;
5. store control unit and send stopping signal to autostop driver element, autostop driver element controls warp knitting machine shut-down operation.
The technical scheme of the application, directly takes the image of the yarn at warp knitting machine sley point place and knitting needle place by high-speed camera unit, first gather and the figure warp thread picture of storing memory standard, namely do not have the figure warp thread picture of broken yarn.In the warp knitting machine course of work, the high-speed camera unit figure warp thread picture that ceaselessly captured in real-time is to be detected, and compare analysis with the figure warp thread picture of standard; if the photo photographed occurs different from normal photo; namely judge that there is flaw certain, order main shut-down system, complete Defect Detection function.
Have the following advantages compared with conventional art: the technique of (1) not Water demand cloth cover, only judges whether the yarn at sley point place and knitting needle place has broken yarn, directly simply; (2) do not affect by cloth cover retraction, the yarn limit on most limit can be taken, there is no check frequency; (3) directly take broken string, reflection in time, just has reflection after not needing to weave defective cloth, fast directly.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
