Description
Technical field
The utility model belongs to the material detection technique field in tobacco processing, is specifically related to reject in tobacco peduncle processing course the method that cigarette turns.
Background technology
The thick and stiff vein of offal and tobacco leaf, is one of primary raw material of pipe tobacco, grows and support tobacco leaf on tobacco rod, is the part of tobacco leaf, account for leaf heavy 25% ~ 30%, and cigarette to turn be exactly the connecting portion of offal and tobacco rod on tobacco leaf.Offal after wind dispensing is processed to thickness, bar different in size, and in fact therefore can say that cigarette turns is exactly the part of offal, and cigarette turns and must comprise a bit of offal in other words.The cross sectional shape of offal is nearly U-shape, generally its Breadth Maximum is called offal diameter in industry, offal diameter is along its length consistent substantially, has one end to be that the cigarette usually said in industry that is of the connecting portion of offal and tobacco rod turns, also make stalk turn in strip offal, cigarette turns and broadens gradually at the diameter of length direction, in trapezoidal shape, being commonly called as concentric reducer, there is obvious difference in the diameter at its two ends, diameter at butt end is generally greater than 10mm, and is about 1.5 ~ 2 times of top diameter.Cigarette turns that structure is hard, and become lignifying, not easily runs through in terrier operation, and enter pressure stalk operation and can cause the frequent putty of pressure roller, and not easily expand after chopping, directly affect the quality of cigarette product, therefore general being turned by cigarette is considered as foreign material, needs rejecting.
At present, the equipment that in tobacco business, rejecting cigarette turns is Purely mechanical, mainly contain vibratory sieve and rotary screen two profiles formula, its screening offal and the principle that turns of cigarette are all based on above-mentioned difference physically between the two, offal and cigarette are turned screening and open by the gap formed between the steel pipe by sieve screen apertures or one group of parallel arranged, and complete separation process by respective transfer passage.Problems existing has 2 points, and be first that between sieve screen apertures or pipe, gap easily blocks, affect screening effect, although be developed so far some equipment manufacturer to have set up automatic cleaning apparatus, effect is still undesirable; Next exists sieve and leak sieve phenomenon, namely should not sieve the cigarette got off turn sift come, and this sieve gets off, offal does not have sieve to get off, equipment can not reach the designing requirement of anticipation, it is in different poses and with different expressions that main cause is that cigarette turns with the size of offal, shape, be difficult to go to adapt to completely with a kind of fixing mesh or gap size, although mesh or gap size are designed to adjustable by Ye You producer, practical significance is little.
Summary of the invention
The purpose of this utility model solves the deficiency that above-mentioned prior art exists, and proposes a kind of method of turning based on the rejecting cigarette of machine vision and device, to improve effect and the reliability of cigarette knot eliminating.
The purpose of this utility model is achieved through the following technical solutions:
Reject based on machine vision the device that cigarette turns in offal, the utility model is characterised in that, described device involving vibrations conveyer, the high-speed belt conveyor be connected with jigging conveyer, is arranged on the eliminating system of high-speed belt conveyor back segment; Wherein, eliminating system comprises image acquiring device, lighting source, background light source, image processing system, the rejecting valve being positioned at high-speed belt conveyor rear end, offal passage, cigarette turn passage; Image acquiring device; Wherein lighting source and background light source lay respectively at the both sides up and down in material face, and two lighting sources are placed in the left and right sides of image acquiring device scan line respectively, and become 30 ~ 45 degree of inclination angle optically focused on the scan line in material face.
Reject according to said apparatus the method that in offal, cigarette turns to comprise the steps:
The first step, offal are discrete: first make offal uniform spreading tankful cross direction by the effect of jigging conveyer, are tentatively paved, close to single-layered state at cell body length direction simultaneously; Offal through tentatively paving is accelerated after entering high-speed belt conveyor, finally makes offal on zone face, present complete discretization state;
Second step, gather image: the offal after above-mentioned steps process, by the collected offal original image be transferred to image processing system of time below image acquiring device;
3rd step, image procossing: rejecting signal, after binaryzation and cigarette turn identifying processing, is issued rejecting valve by the offal original image collected;
4th step, rejecting process: reject signal and send instruction to rejecting valve by image processing system, will be mingled in the cigarette knot eliminating in offal, the cigarette of rejecting turns into and turns passage into cigarette, and offal then enters offal passage.
Wherein the 3rd step image procossing comprises following steps:
A, binary conversion treatment: original image is carried out binary conversion treatment and obtains binary image;
B, binary image carry out compaction algorithms: first being carried out compression of images between two by the row pixel data of image with computing is 1/2, then the adjacent rows of the image through compressing first and two row pixel datas 4 are one group to merge, 4 pixel datas are added up and obtains a new pixel data, such data again boil down to original 1/4, after twice compaction algorithms, Image Data Compression is 1/8 of former binary image;
C, sieve computing is carried out to compressed image: with the sieve of a n × n, with the pixel size after a compression for step-length travels through whole image.Often moving moves a step obtains m by cumulative for the pixel data in sieve overlay area, compares the size of m and threshold values k, as m >=k, judges that this position is turned as cigarette, be recorded in current location and reject in gating matrix table;
D, generation cigarette knot eliminating signal: utilize the position corresponding relation of rejecting gating matrix table and rejecting valve, generation cigarette knot eliminating signal.
In the utility model, the number n of n × n sieve can by formula:
round up and obtain, in formula, w is mean breadth, s that cigarette turns is the linear resolution of camera, and threshold values k gets 0.8 to 0.9 times of n value, so by the size of adjustment w value, can control the recognition effect of sieve.
The transporting velocity scope of high-speed belt conveyor described in the utility model is 3m/s ~ 7m/s, and variable ratio frequency changer speed governing.The length of described scan line equals the belt width of high-speed belt conveyor, and the horizontal range B of the discharge roller of scan line and high-speed belt conveyor is 10mm ~ 30mm.
The utility model is by carrying out width 1/4 and compress and after short transverse 1/2 compresses, utilize sieve method to detect cigarette fast and turn position, detection method being quick, efficient, real-time, can meet the requirement of real-time that ONLINE RECOGNITION is rejected to binary image.Turn by adjustment cigarette the number that mean breadth parameter w can change sieve, effect is rejected in adjustment, compensate for the deficiency of existing pure mechanical occluding technique.
