The invention provides a non-contact type automatic detecting method for the broken ends of the spandex warping on the basis of image analysis and comprises the following steps: (1) utilizing an industrial camera, a computer chip, a light source, a programmable controller, and the like, and installing an automatic detecting system for the broken ends of the spandex warping on a present spandex warping machine; (2) utilizing the industrial camera to collect spandex yarn images during a warping process and inputting the collected images to the computer chip; (3) utilizing an image analysis technology to process the spandex yarn images and counting the number of the spandex yarns in the images; and (4) judging if the spandex yarns have the broken ends during the warping process according to a detecting result of the number of the spandex yarns, and if the broken ends exist, inputting a signal to the programmable controller, controlling the spandex warping machine by the programmable controller and stopping the spandex warping machine.
Description
Technical field
The present invention relates to a kind of contactless spandex warping break detecting method, with industrial camera, computing chip, light source and Programmable Logic Controller etc., in existing spandex warping machine assembling spandex warping broken end automatic checkout system, it belongs to the fabric detection field, is specifically related to the collection of spandex yarn line image and treatment technology, automatic control technology etc.
Background technology
Warping is fabric width and the length that the warp thread of certain radical is stipulated by technological design, with uniform, the suitable technical process of tension force close wind on warp beam or beam of a loom, is one of critical process of knitting front preparation.The quality of warp beam or beam of a loom quality will directly have influence on the quality of slurry axle and the efficient of loom, and will be very large on production efficiency and the product volume impact of next operation.Whether the warping end break self-stop in time is a principal element of beam of a loom or warp beam winding quality quality.
The warping machines broken yarn detection system of at present textile industry use can be divided into two classes substantially: a class is mechanical type electrical contact formula checkout gear, such as the drop type checkout gear; Another kind of is the electronic type checkout gear, such as capacitance type sensor and electro-optical pickoff checkout gear etc.For the high elasticity yarn, spandex for example, the menopause tablet own wt can make spandex produce very large deformation, to the additional additional tension of spandex, and easily causes system's broken yarn erroneous judgement.Traditional contact-type detection, its core is finished broken yarn with menopause tablet and is detected, this performance limitations of spandex the use of traditional mechanical type and electronic type detection system, this just requires should use sensitiveer, reliable noncontacting proximity sensor to the warping broken yarn detection system of spandex, reduces the contact point of elastomeric yarn and machine as far as possible.
The present invention has provided a kind of contactless spandex warping broken end automatic testing method based on graphical analysis.Invention comprises following content: (1) utilizes industrial camera, computing chip, light source and Programmable Logic Controller etc., in existing spandex warping machine assembling spandex warping broken end automatic checkout system; (2) utilize industrial camera to gather spandex yarn line image in the warping process, and the image that collects is input in the computer chip; (3) utilize image analysis technology that the spandex yarn line image is processed, the spandex yarn radical in the statistical picture; (4) whether according to the testing result of spandex yarn radical, judging has the spandex yarn to break end in the warping process, as broken end occurs signal is input in the Programmable Logic Controller, by the Controlled by Programmable Controller spandex warping machine, makes its parking.The idiographic flow that the spandex Yarn break detects as shown in Figure 1.
Summary of the invention
The purpose of this invention is to provide a kind of contactless spandex warping break detecting method, be used for the automatic detection of spandex warping process Yarn break.The technical solution used in the present invention is as follows:
(1) utilizes industrial camera, computing chip, light source and Programmable Logic Controller etc., at spandex warping machine spandex Yarn break automatic checkout system is installed, be used for the non-contact automatic detection at warping process spandex Yarn break;
(2) camera can collect spandex warping machine all spandex yarn line images in the warping process, and the spandex yarn is clear and legible, every spandex yarn accounts for 1 independently pixel at least, and camera can be transported to the spandex yarn line image that collects in the computing chip by data-interface;
(3) computing chip can obtain the spandex yarn line image that industrial camera collects by data communication interface, and finish the spandex yarn line image and process, detect the spandex yarn radical that comprises in the image, to judge whether spandex breaks end in the warping process, and can testing result be transported in the Programmable Logic Controller able to programme by output interface, the computing chip that adopts can be to finish computer CPU, dsp chip, ARM chip and the fpga chip etc. that image is processed;
(4) Programmable Logic Controller is accepted the broken end testing result of computing chip by data communication interface, and when broken end occured, the main frame of control spandex warping machine made its parking, finishes the spandex yarn wire terminal by the workman.

The specific embodiment
Fig. 2 is spandex Yarn break automatic checkout system in the spandex warping process.Cheese 1 is positioned on the bobbin cradle 2, and bobbin cradle commonly used is combination vehicle formula bobbin cradle; Yarn said that lease reed 3 finished preliminary combing, and then by lever jack 4 and back reed 5, the spandex yarn is arranged evenly gradually; After through guide rod 6, the spandex yarn arrays is even and smooth, and light source 7 and industrial camera 8 are installed between cord roller 6 and lever jack 10, finishes the collection of spandex yarn line image; After detecting Yarn break, the signal that will break end flows to spandex warping machine, and machine is stopped.
The IMAQ point that the present invention proposes also has a segment distance apart from warp beam 15, can avoid broken yarn to be involved in layer behind the system identification Yarn break, in time stops, and can prevent lappers, strand head, thereby improve warp quality.
Fig. 3 is the spandex yarn line image that collects in the width of cloth invention example, and this moment, yarn breaked end.Spandex yarn line image when Fig. 4 breaks end for generation.
In computing chip, do threshold process to collecting the spandex yarn, be partitioned into the position of yarn.In the invention example, below the spandex yarn, place black background, light source adopts White LED light source, contrast is larger between yarn and the background, it is comparatively easy that threshold value is selected, in the invention example with the average of entire image as threshold value, finish cutting apart of spandex yarn line image, Fig. 5 is the Threshold segmentation result of Fig. 3.
Select image middle row pixel shown in Figure 5 as the counting line of spandex yarn radical, traversal when being transitioned into white yarn point by the black background point in the image, adds 1 with spandex yarn radical from left to right.
When the spandex yarn breaks end, the spandex yarn radical that detects can reduce, and the signal that will break end this moment sends to Programmable Logic Controller, sends stop sign by Programmable Logic Controller, controls the spandex warping machine Main Engine Cut-Off, is finished the joint of broken yarn by the workman.
