Description of drawings
Fig. 1 is the structural representation that monitoring of the present utility model detected and rejected the device of foreign matter in the cigarette;
Fig. 2 is the resonance characteristic curve map of microwave cavity.
The specific embodiment
In applying for a patent " microwave off-line material humidity and Density Detection method ", the resonant frequency of the microwave cavity that test macro is measured and resonance amplitude have been described and the humidity of the material of being filled and the relation of density.Under the situation that normal pipe tobacco is filled, because tight head and the density of non-tight variable density and pipe tobacco and the influence of some fluctuation of humidity itself during cigarette props up, measured resonant frequency Δ F and resonance amplitude Δ U always change in the certain up and down scope of its mean value, as shown in Figure 2.But when having foreign matter to exist in the pipe tobacco, the measured resonant frequency and the variation of resonance amplitude will substantially exceed the situation that normal pipe tobacco is filled.
The utility model is described in further detail below in conjunction with accompanying drawing.
See also Fig. 1, there is shown a kind of device that detects and reject foreign matter in the cigarette of the present utility model, in cigarette machine (not shown) production process, cigarette Zhi Jinhang is detected in real time.Include synchronous device for eliminating 12 in this cigarette machine, the utility model comprises the microwave signal generator 1 that links to each other successively, the first microwave signal isolator 2, signal input probe 3, microwave spill resonator 4, signal output probe 5, the second microwave signal isolator 6, detector amplefier 7, A/D converter 8, signal processing circuit 9, data acquisition and processing (DAP) computer 10, data acquisition and processing (DAP) computer 10 outputs signal to a display 11 and synchronous device for eliminating 12 respectively, and receive the input signal of a cigarette machine real-time speed checkout gear 13, the system control unit 14 that also comprises a control microwave signal generator 1 and signal processing circuit 9, the first microwave signal isolator 2 of Xiang Lianing successively, signal input probe 3, microwave spill resonator 4, signal output probe 5, the second microwave signal isolator 6, link to each other by the microwave coaxial cable (not shown) between the detector amplefier 7.
Prop up in order to make device for eliminating can accurately reject the defective cigarette that contains foreign material, detect the real time execution speed of cigarette machine with cigarette machine real-time speed checkout gear 13, thereby calculate device for eliminating moment of opening, these data are inputed to data acquisition and processing (DAP) computer 10 reject synchronously, to avoid causing mistake to reject to control synchronous device for eliminating 12.
The generation of microwave signal reaches with the synchronous of signal processing and waits work by system control unit 14 controls.
Microwave has resonance characteristic in a metal container (microwave cavity).For the microwave cavity of a sky, after the geometry of resonator was determined, its resonant frequency and resonance amplitude were also determined.But when when this intra resonant cavity is divided or all is filled with other nonmetallic substance (we are called dielectric material), its resonant frequency and resonance amplitude can be different because of the dielectric constant of the dielectric material of filling, the different of what and shape of dielectric material produce different variations.This variation is very responsive for the response that difference produced of the dielectric material of being filled.We have developed cigarette with the microwave resonance technology and have propped up online weight and Humidity Detection system.Because the dielectric constant of normal pipe tobacco and the dielectric constant of other foreign matter have very big difference, therefore, we can utilize various metallic foreign bodies or the non-metal foreign body dielectric material that the variation of the resonant frequency of microwave cavity and resonance amplitude is measured in the microwave cavity to be filled quickly and accurately.
At the specific (special) requirements that the cigarette machine cigarette props up the polymorphic type of foreign material, many sizes and different shape, adopted microwave spill resonator as the foreign material acquisition sensor, realized that high speed, noncontact, high accuracy detect.Because its microwave resonance frequency and resonance amplitude are extremely responsive to the dielectric constant of various different materials, thus the material of very small dimensions, all kinds, different shape can be detected, and also its certainty of measurement also can be done very highly.
Detector amplefier 7 can adopt general microwave detector diode, carries out direct current after the detection again and amplifies, and is output as d. c. voltage signal after the amplification.For the stability that improves system must be carried out temperature-compensating to detection and amplifying circuit.
D. c. voltage signal after signal processing circuit 9 is amplified detection becomes data signal through analog-to-digital conversion.Each detecting signal is constantly sent in the data acquisition and processing (DAP) computer 10.Since microwave signal generator 1 be one by numerically controlled fast frequency-hopped phase-locked microwave source, each is constantly corresponding to a microwave signal frequency.Relatively each output signal size constantly can be tried to achieve the real-time resonance characteristic of resonator, thereby be obtained at that time microwave resonance frequency and resonance amplitude.When tested cigarette in the resonator props up when containing foreign material, the resonant frequency of microwave cavity and resonance amplitude also will change.Again according to the resonant frequency of microwave cavity and the relation of resonance amplitude and filler, by Computer Processing, judge corresponding relation unusual of resonant frequency and resonance amplitude, thereby identify the existence of foreign matter.
The utility model all has higher detection sensitivity to various metallic foreign bodies or non-metal foreign body (as wire, timber, plastics, rubber, glass and stone etc.), thereby, be a kind of desirable device that detects foreign material in the tobacco.This device also can be used for the Non-Destructive Testing of inner foreign matter in other nonmetal bar-shaped manufacture of materials process.
The utility model can be used as the tobacco business cigarette and props up the metal in the production process and the detection and the rejecting of non-metal foreign body.Can be used for for example various cigarette units such as PROTOS, PASSIM, SUPER9, MK95, GD121.
Above embodiment is only for the usefulness that the utility model is described, but not to restriction of the present utility model, person skilled in the relevant technique, under the situation that does not break away from spirit and scope of the present utility model, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.
