Description
Technical field
The present invention relates to a kind of method and apparatus detecting packaging and leak, be specifically related to a kind of flexible package punch leak hunting method and device.
Background technology
At present, in a lot of industry, liquid product usually adopts packed in flexible pouchy, as milk in bags, jelly cup, fruit juice bag etc.During production, the automatic packaging machine that adopts completes the flow process such as bag, encapsulation more.In process of production due to the leakage of heat sealing seal, press wear or material itself the reason such as crack, micropore and cause poorly sealed, packaging leak.If flexible package punch exists leakage, not only impact is produced and transportation environment, more has influence on the quality of product.Existing flexible package punch leak detection mode mostly is artificial leak detection, or the leak detection of high end instrument, the former overspending manpower, the latter's high cost.
Summary of the invention
For solving the deficiencies in the prior art, the object of the present invention is to provide a kind of accuracy of detection is high, speed is fast, cost is low flexible package punch leak hunting method and device.
In order to realize above-mentioned target, the present invention adopts following technical scheme:
A kind of flexible package punch leak hunting method, comprises the steps:
S1, flexible package punch to be detected to be extruded through pressure apparatus;
S2, the squeezed flexible package punch pressed through is delivered to excitation source under irradiate;
S3, receptor obtain the spectral information of flexible package punch;
S4, utilize that liquid is different with the spectral information of packaging to carry out judging and processing: when the spectral information that receptor obtains exceedes threshold value, then judge that this flexible package punch is revealed, processing module is carried out leakage and processed; When the spectral information that receptor obtains is lower than threshold value, then judge that this flexible package punch is not revealed, processing module does not reveal process.
Aforementioned leakage is treated to alarm.
Liquid in aforementioned flexible package punch to be detected can produce a specific emission spectrum information after the excitation source of selected wavelength irradiates, flexible package punch be packaged in the excitation source irradiation of this selected wavelength after then can not produce or produce different emission spectrum information.
In addition, present invention also offers a kind of device being applicable to aforesaid flexible package punch leak hunting method, comprise: pressure apparatus, excitation source, receptor and processing module, whether flexible package punch to be detected irradiates under being placed in excitation source and is leaked by receptor detection fluorescence spectrum information and then tracer liquid packaging, and performs subsequent treatment (leak process or do not reveal process) by processing module.
Preferred as one, aforementioned receptor is made up of APD detector and filter, and filter is band-pass filter, by means of only the fluorescence spectrum wave band of liquid stimulated emission.
Usefulness of the present invention is: the invention provides and be applicable to the non-damaged data of flexible package punch and the method and apparatus of on-line checkingi, reasonable in design, accuracy of detection is high, and speed is fast, greatly save human resources, and cost is lower.
Accompanying drawing explanation
Fig. 1 is the structural representation of leak detection device for liquid packaging of the present invention.
The implication of Reference numeral in figure: 1, pressure apparatus, 2, flexible package punch, 3, excitation source, 4, receptor, 5, processing module.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, concrete introduction is done to the present invention.
See Fig. 1, a kind of flexible package punch leak hunting method of the present invention, comprise the steps: first, flexible package punch 2 to be detected is extruded through pressure apparatus 1, pressure size is moderate, to ensure the there is leakage that the packaging of leaking or leaking hidden danger reaches detection condition, but can not the packaging good to leak tightness damage; After completing extruding, the squeezed flexible package punch 2 pressed through is delivered to excitation source to irradiate for 3 times, the liquid leaked out is meeting emitting fluorescence spectrum under the irradiation of excitation source 3, and flexible package punch 2 LASER Light Sources in this wavelength irradiate lower unstressed configuration spectrum generation, then the difference of this optical property is utilized, got the spectral information of flexible package punch 2 by receptor 4 detection, can judge whether packaging leaks; When the spectral information (fluorescence intensity) that receptor 4 obtains exceedes threshold value, then judge that this flexible package punch 2 is revealed, processing module 5 carries out leakage process, the measures such as such as alarm; When the spectral information (fluorescence intensity) that receptor 4 obtains is lower than threshold value, then judge that this flexible package punch 2 is not revealed, processing module 5 does not reveal process.In actual mechanical process, according to the difference of liquid, select threshold value suitable accordingly, this is readily appreciated that and realizes, and does not repeat herein.
That is, method of the present invention make use of: the liquid in flexible package punch 2 to be detected can produce a specific emission spectrum information after the excitation source 3 of selected wavelength irradiates, then can not produce or produce different emission spectrum information after the excitation source 3 being packaged in this selected wavelength irradiation of flexible package punch 2, according to the difference of this optical property, realize non-damaged data and on-line checkingi accurately, fast, at low cost.
As shown in Figure 1, device of the present invention, comprise: pressure apparatus 1, excitation source 3, receptor 4 and processing module 5, whether flexible package punch 2 to be detected is placed in excitation source 3 times and irradiates and detect fluorescence spectrum information and then tracer liquid by receptor 4 and pack 2 and leak, and performs subsequent treatment (leak process or do not reveal process) by processing module 5.Preferred as one, receptor 4 is made up of APD detector and filter, filter is band-pass filter, by means of only the fluorescence spectrum wave band of liquid stimulated emission, thus guarantee that receptor 4 gets flexible package punch 2 through the postradiation useful optical information of excitation source 3, other interference optical information is fallen in automatic fitration, improves accurate measurement precision and accuracy.
More than show and describe groundwork of the present invention, principal character and advantage.The technical personnel of the industry should be understood, and above-described embodiment does not limit the present invention in any form, the technical scheme that the mode that all employings are equal to replacement or equivalent transformation obtains, and all drops in protection scope of the present invention.
