Abstract
A method for adding perfume or raw material on the production line to prepare tobacco shreds from tobacco leaves includes such steps as putting the liquid material drum on sensor connected to a weighting instrument, displaying the weight of material via conversion, and automatically controlling the addition of perfume or material by the upper-layer machine connected with said weighting instrument. Its advantage is high control accuracy.
Description
Technical field
The present invention relates to a kind of method of adding perfume (or spice)/material, especially be applied to the perfuming/charging process that can accurately control on the tobacco leaf throwing line.
Background technology
The general employing of perfuming/charging system is electromagnetic flowmeter volume type measurement Law on the existing tobacco leaf throwing line, and mainly there is following defective in this method: (1) adopts electromagnetic flowmeter volume type measurement Law, owing to be subjected to the influence of density and tubular, error is big; (2) its perfuming (material) precision depends primarily on electromagnetic flowmeter, and the Electromagnetic Flow meter calibrating is comparatively complicated, is subject to the pollution of material and the influence of corrosion and material variety; (3) distance of spices room and perfuming (material) machine is longer, and perfume/material can't be estimated midway, is unfavorable for stock's control and production procedure control, can not know also surplus how many unspent materials in the bucket well.
The cigarette process standard that State Tobacco Monopoly Bureau issues, requiring the perfuming precision is 0.5%, and charging precision is 1%, and the above defective of prior art is that the interpolation and the control of perfume/material in the industrial production has brought very big influence, can not reach the technological requirement of defined.
Summary of the invention
The objective of the invention is to overcome the defective of prior art, provide a kind of easy to operate, control to be used for the perfuming/charging process of tobacco leaf throwing line accurately.
Perfuming/the charging process that is used for tobacco leaf throwing line of the present invention is made up of following steps:
One, the bottom that the charging basket of feed liquid will be housed places on the sensor, and sensor links to each other with weighting display instrument by cable;
Two, weighting display instrument is converted to voltage signal with the weight signal of sensor output, and scaling transformation becomes data signal, and shows weight of material;
Three, weighting display instrument is connected with host computer by interface, and by host computer perfuming/feeding quantity is controlled automatically.
Described host computer is computer or technology line traffic control cabinet, and weighting display instrument can directly be connected with computer by RS232, RS422/485, also can carry out communication by analog quantity or Profibus network or Ethernet and technology line traffic control cabinet.
The present invention has following advantage: the method for the invention is only stressed relevant with sensor, and is irrelevant with feed liquid density and tubular, directly measures feed liquid weight; Required precision to electromagnetic flowmeter suitably reduces, even can replace electromagnetic flowmeter.And can directly show current feed liquid weight, more help production procedure control.The present invention has overcome the deficiencies in the prior art, has improved perfuming/reinforced control accuracy, has strengthened stock's control and production procedure control, and can judge to remain in the charging basket what are expected, how many materials has in real time, detects reliably, and maintenance safe conveniently.
Description of drawings
Fig. 1 is a process chart of the present invention.
Fig. 2 is an installation drawing used herein.
Among the figure: among the figure: 1-perfuming/charging bucket, 2-sensor, 3-weighting display instrument.
The specific embodiment
The charging basket 1 that feed liquid is housed of the present invention places on the weighing platform, under the gravity effect, LOAD CELLS 2 elastomers produce deformation, make the strain ga(u)ge bridge circuit disequilibrium that is pasted on the elastomer, output and proportional millivolt of voltage signal of weight data, this signal enters Displaying Meter 3, becomes data signal after linearity amplification and A/D conversion, weight signal is handled and directly shown on instrument the weight data of perfume/material by microprocessor.The weighing-up wave of charging basket directly enters upper computer control system, and the data of directly weighing can be judged whether expect sky in the charging basket, remain what are expected, and can in time indicate the unusual clear condition in the charging basket, and therefore the characteristics that detection is accurate, be convenient to keep in repair are arranged.This weight signal and feed liquid density are irrelevant, irrelevant with the charging basket shape, perfume/material evenly adds in the pipe tobacco by perfuming/material pump in perfuming/charging basket, when charging basket adds feed liquid, the value of weighing that can directly obtain feeding in the bucket from weighing instrument is W1, along with perfume/material adds pipe tobacco, the charging basket value of weighing will reduce, can directly from weighing instrument, must be the current feed liquid net weight W2 of certain hour (for example 3 seconds), feed liquid weight is subtracted each other the perfuming/material amount (W1-W2) that can get in the corresponding time period in the charging basket that obtains for twice with front and back, calculate and to carry out the PID adjusting to perfuming/charger in real time with setting perfuming/material ratio according to the tobacco leaf weight that electronic scale flows through in the corresponding time period again, to improve perfuming/charging precision.Feeding quantity is set: SP=K*FF=inlet scale flow, the reinforced ratio of K=is set.If W2＜W1, expression perfuming/charging system is working properly, and every interval certain hour is judged the variable quantity of front and back weighing-up wave and then carried out perfuming/feeding quantity control.If W2 〉=W1 then represents to work under perfuming/charger abnormal condition, with alarm.When ordinary production, if material is very few, perfuming/reinforced weighing device sends reinforced signal to be stopped to produce completely to the processing line electrical control cubicles, waits for after perfuming/materials device has added feed liquid and can produce completely once more.The size of setting feeding quantity is determined by reinforced ratio and the electronic scale instantaneous flow rate signal that operating personnel set, setting feeding quantity compares with the actual feeding quantity that the weighing system of sensor composition provides, comparative result control frequency converter output frequency changes the charge pump motor speed, what of the tobacco leaf flow that the flow that makes pump output feed liquid records with electronic scale change, thereby reach quantitatively perfuming/reinforced automatic control in proportion.
Above-mentioned LOAD CELLS is selected Weighing module for use, and the quantity of Weighing module is by the decision of the quantity of container support pin.This perfuming weighing system adopts 3 point-supported tank scale structures, and the load active force can be assigned on every sensor equably, has avoided sensor to cause the phenomenon that distorts because of unbalance stress, thereby has improved weighing precision.Weighting display instrument is with the weight signal of sensor output, be converted to a millivolt voltage signal, scaling transformation becomes the weight numeral, and the demonstration weight of material, weighting display instrument 3 can provide 0-10V, 4-20mA signal, also can directly be connected with computer by RS232, RS422/485, also can directly go up the technology network, as networks such as Profibus, InterBus, directly feed liquid is weighed and show, and participate in the control of perfume/material proportioning and the stock control of feed liquid.
