Description of drawings
Fig. 1 is the block diagram that the online plume bag of a kind of microwave of the utility model lacks package detection device.
Embodiment
As shown in Figure 1, the utility model, be that the online plume bag of a kind of microwave lacks package detection device, comprise and survey loudspeaker scanning moving guide rail 8, be installed in the detection loudspeaker of surveying on the loudspeaker scanning moving guide rail 83, control motor 7 is moved in the detection loudspeaker scanning that links to each other with detection loudspeaker 3, pick-up unit body 1 that links to each other with detection loudspeaker 3 and the power supply 10 that lacks the package detection device power supply to the online plume bag of microwave, wherein, surveying loudspeaker 3 is the open square type of H face waveguide trumpet, opening angle exceeds with the length of plume bag 2, its centre frequency is 2.5GHz, makes the system works frequency in the wireless industrial electricity band limits of regulation.
Pick-up unit body 1 comprises:
System control module 16, according to extraneous enabling signal, be used to control the sweep velocity of surveying loudspeaker 3 and with signal processing synchronously, the generation of microwave signal, and move control motor 7 output control signals to surveying loudspeaker scanning.
Microwave signal generator 11 is connected with system control module 16, and the control signal of receiving system control module 16 outputs is used to produce a microwave signal.
Microwave signal separation vessel 12 with microwave signal generator 16 and survey loudspeaker 3 and is connected, will and be surveyed the microwave signal that loudspeaker 3 receive from microwave signal generator 16 and separate, and the signal after surveying the corresponding separation of loudspeaker 3 outputs.
Detector amplefier 14 is connected with microwave signal separation vessel 12, and will carry out detection and direct current from the signal that microwave signal separation vessel 12 receives and amplify, and the output dc voltage signal.
Signal processing module 15, be connected with detector amplefier 14 and system control module 16, according to the control signal that receives from system control module 16, will carry out analog to digital conversion and signal from the d. c. voltage signal that detector amplefier 14 receives relatively, and export corresponding signal and pulse.
Data acquisition and processing (DAP) module 19 is connected with signal processing module 15, will handle from signal and pulse that signal processing module 15 receives, and export corresponding processing signals, comprises rejecting signal, alarm signal, count signal.
Principle of work of the present utility model is: can produce decay during the microwave penetrating mass transfer, the material that exists in the microwave transmission approach is many more, and microwave signal is attenuated strong more.When microwave signal runs into metallic material, can all reflect on its surface, because the material that is passed through in the approach of microwave signal transmission and reflection is how much different, the intensity of its reflected signal is difference also.Utilize its this characteristic, detect reflection strength, can distinguish in the plume tobacco bale and completely wrap or lack bag by microwave signal behind the plume box.
System control module 16 controlled microwave signal generators 11 produce the microwave signal of certain frequency, give by microwave signal separation vessel 12 and survey loudspeaker 3.Surveying loudspeaker 3 is transmitted into microwave signal on the tested plume bag 2, and,, be detected loudspeaker 3 and receive once more by behind the tested plume bag 2 by sheet metal 21 reflection at tested plume bag 2 back sides, and, send detector amplefier 14 to by microwave signal separation vessel 12.The faint microwave signal that detector amplefier 14 will receive is carried out detection and amplification, the output dc voltage signal, and give signal processing module 15.Signal processing module 15 is made analog to digital conversion with d. c. voltage signal, becomes digital voltage, and each signal magnitude constantly relatively is because the detecting circuit when lacking bag should have tangible increase by the voltage when completely wrapping; If two bags all lack, voltage should be bigger, therefore is judged as to lack bag when signal amplitude is higher than certain value, exports a scarce bag and reject signal, should lack bag and reject the installation situation that the thresholding of signal should lack packet system according to cigarette machine, the plume trade mark, microwave, determine by experiment; Signal processing module 15 is also exported a gating pulse simultaneously, determines to lack the plume box of bag with this.Signal processing module 15 will lack bag rejecting signal and gating pulse is delivered in the data acquisition and processing (DAP) module 19, by 19 pairs of signals of data acquisition and processing (DAP) module analyze, conclude, processing such as identification, signal, alarm signal, count signal are rejected in output at last, rejecting, alarm, to count, and the processing that the various information of the plume bag produced are stored.
Because five bag cigarettes are arranged in the cigarette side by side, in order to detect simultaneously, surveying loudspeaker 3 is installed on the detection loudspeaker scanning moving guide rail 8, by survey loudspeaker scanning move 7 controls of control motor carry out laterally about scanning, so that the cigarette case of diverse location in the plume bag 2 is surveyed, plume bag 2 travels forward along transport tapes, in plume bag 2 travels forward time of deck bar, survey loudspeaker 3 (or to the right) run-down left, (perhaps run-down) back and forth.If therefore in the plume bag 2 situation that lacks bag is arranged, in a scan period, can both be detected.Even under the situation that lacks package location and full package location dislocation, omission can not take place yet.
In the utility model, system control module 16 can adopt general monolithic processor, as the MCS-51 series monolithic of TI company.Microwave signal separation vessel 12 can adopt the microwave circulator of this frequency range, as the product of Nanjing 898 factories production.Detector amplefier 14 can adopt general microwave detector diode.Signal processing module 15 can adopt 8 analog to digital converters and monolithic processor, as MCS-51 series monolithic processor and 8 analog to digital converters of TI company.Data acquisition and processing (DAP) module 19 can adopt computing machine.Owing to only need to work in single-frequency, so microwave signal generator 11 can adopt microwave-medium resonance resonator oscillator, the product of being produced as China Electronic Science and Technology Corporation the 55th, be characterized in that volume is little, frequency stability is high, this oscillator work centre frequency is 2.5GHz, output power is set at 10mW, and its frequency stability is better than 5 * 10
-5/ hour, its radiation intensity at operating position only is 0.1mW/cm
2
In sum, the utility model can carry out online detection rapidly, continuously to the scarce bag situation of plume box, does not influence the operate as normal of plume packaging machine, its accuracy in detection and reliability height, distinguishable plume lacks a bag or lacks two bags, and not because of the such environmental effects detection accuracy.In addition, the utility model also has advantages such as safe and easy for operation.
Below embodiment has been described in detail the utility model in conjunction with the accompanying drawings, and those skilled in the art can make the many variations example to the utility model according to the above description.Thereby some details among the embodiment should not constitute qualification of the present utility model, and the scope that the utility model will define with appended claims is as protection domain of the present utility model.
