Description
Technical field
The present invention relates to grow tobacco processing detection technique and an equipment, particularly a kind of method and apparatus that utilizes weight method on-line determination tobacco structure.
Background technology
In the production of cigarettes process of tobacco business; And in the quality testing to cigarette product; Pipe tobacco size detection to pipe tobacco all is important link; It clearly reflected cigarette throwing, pipe tobacco mix join, the quality control situation of each operation such as cigarette, the tobacco structure of finished cigarettes also directly affects the physics and the aesthetic quality of cigarette.At present China cigarette factory to measure tobacco structure mostly be to adopt grab sample static measurement method (to see industry standard: the mensuration of the assay method of YC/T178-2003 tobacco whole cut rate, filament broken rate and YC/T278-2009 cigarette composition tobacco structure); Used instrument can only rely on hand sampling, Static Detection, per tour time to extract individual samples, staticly carry out check and analysis, decision-making foundation be provided afterwards; The tobacco structure that adopts this method to record is discrete bigger; Far can not reflect tobacco structure variation in process of production timely and accurately, more be difficult to it is controlled.Still the equipment or the method that do not have at present online direct mensuration tobacco structure.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of method and apparatus of on-line determination tobacco structure, thus can online in real time accurately detect tobacco structure.
Be to realize above-mentioned purpose, the invention provides a kind of equipment of on-line determination tobacco structure, mainly comprise the sieve that shakes, airduct, Pneumatic reverse turning bed, connect offal pipe, long-pending last case, electronic scale and processor controls; The said sieve that shakes comprises feed end and discharge end; Said airduct is positioned at the discharge end below of the sieve that shakes, and offers side opening on the said airduct, connects the offal pipe and through side opening airduct is communicated with long-pending last case; Said electronic scale is arranged at long-pending last case below; And link to each other with processor controls, a said Pneumatic reverse turning bed end is fixed on the airduct side opening, but an end is the free end arbitrary overturn.
Place the long-pending last funnel under the sieve that shakes to connect the negative pressure airduct respectively and connect the offal pipe through Pneumatic reverse turning bed.When Pneumatic reverse turning bed closing, the screening offal is delivered to the dedusting room by the negative pressure wind manage-style; When Pneumatic reverse turning bed opening, the screening offal flows to long-pending offal case through connecing the offal pipe, and offal is deposited at the bottom of the offal case, is begun to clock and weigh by the electronic scales that is arranged at offal case below, until the end of clocking.The data model of input in advance through in the processor controls promptly can obtain the average tobacco structure data in section detection time, thereby reflect tobacco structure variation in process of production timely and accurately, conveniently the pipe tobacco in producing is controlled.
As improvement of the present invention, the top of said airduct is a funnel-form.Thereby can be so that offal more to be gathered at the sieve discharge end place that shakes, anti-leak-stopping spills.
As the present invention's improvement further, also be provided with display screen on the said processor controls, thereby make data directly to reflect immediately, improve produce controlled.
Simultaneously, the present invention also further discloses the said sieve that shakes and has been the flat screen of sieve diameter 0.8mm～1.5mm.
As with the supporting assay method of the disclosed equipment of the present invention, the invention discloses a kind of method of on-line determination tobacco structure, comprise the steps:
A, shake the sieve feed end and discharge end take a sample respectively; Sampling amount is 1kg; And measure and to obtain that feed end contains last rate a, discharge end contains last rate b, thereby obtain shaking sieve screen rate η according to
;
B, set up the relational model between tobacco structure to be measured and offal weight m, the screen rate η in the laboratory, tobacco structure representes with pipe tobacco whole cut rate W and pipe tobacco filament broken rate B respectively, then its relational model W=k respectively
1M/ η+d
1, B=k
2M/ η+d
2
C, online timing detect the offal weight m at discharge end place in the t time period, and according to the relational model between tobacco structure and offal weight m, the screen rate η, online in real time obtains tobacco structure;
As further improvement, the time t that the online timing among the said step c detects offal weight is 3～7 minutes.
Utilize the disclosed detection step of the present invention, can accomplish online detection tobacco structure, more reasonable to the feasible detection of the setting in the time interval simultaneously, accurately.If the setting of sample time is too short, then sample volume is few, does not have statistical representativeness; If sample time is long; Then sample volume is excessive, and sample is had certain waste, and has prolonged whole sense cycle; So the present invention discloses 3～7 minutes especially, make that whole detection is more reasonable.
Be connected with when the processor controls place under the situation of display screen, the invention discloses a kind of method of supporting on-line determination tobacco structure equipment, it is characterized in that, comprise the steps:
A, shake the sieve feed end and discharge end take a sample respectively; Sampling amount is 1kg; And measure and to obtain that feed end contains last rate a, discharge end contains last rate b, thereby obtain shaking sieve screen rate η according to
;
B, set up the relational model between tobacco structure to be measured and offal weight m, the screen rate η in the laboratory, tobacco structure representes with pipe tobacco whole cut rate W and pipe tobacco filament broken rate B respectively, then its relational model W=k respectively
1M/ η+d
1, B=k
2M/ η+d
2
C, online timing detect the offal weight m at discharge end place in the t time period, and according to the relational model between tobacco structure and offal weight m, the screen rate η, online in real time obtains tobacco structure;
D, processor controls directly react on the tobacco structure that obtains on the display screen.
As the improvement of said method, the time t that the online timing among the said step c detects offal weight is 3～7 minutes.
Adopt the disclosed detection method of the present invention, realized the purpose of the online detection of tobacco structure, thus in making that pipe tobacco is produced, can be in time, accurately tobacco structure is detected, improve produce controlled.Simultaneously, the not only reliable and stable nothing harm of this method, and easy easy operating; For different set detection time, the different trades mark, the pipe tobacco production of different flow; Only need utilize method for establishing model disclosed by the invention, the correction model parameter, and correspondence is upgraded in processor controls; Promptly can be applicable to the structure detection of different trade mark pipe tobaccos, thereby make the detection between the various trades mark transform convenient and swift.
