Definitions
- the invention relates to a device for the simultaneous, continuous measurement and control of the amount of acetate and triacetin in the manufacture of filter rods, in particular for use in the cigarette industry.
- Cigarette filters are an essential, quality-relevant component of cigarettes, which is why great efforts are made to optimize the process for the production of the filter rods. It is important to ensure that the process is regulated as specifically as possible, which of course depends on the most precise and quick characterization of the quality of the products. In the best case, this is done using an online process.
- parameters such as diameter, acetate weight and triacetine content and tensile resistance are determined.
- Off-line methods are usually used to determine acetate weight, tensile strength and triacetine content.
- the acetate weight is determined gravimetrically by determining the gross weight of the rods and deducting the mass of wrapping paper, glue and triacetin from them. Paper and glue quantities are also determined gravimetrically, which are largely process-independent parameters.
- Different methods are used to determine the triacetine content. Firstly, the weight of a defined number of filter rods with and without triacetin is determined. The difference between the two measurements then gives the triacetine content.
- Acetate weight used which can also be used for process control.
- DE 28 15 025 describes the measurement of the density and thus the mass of the finished filter train using a beta emitter.
- This method therefore makes it possible to determine the mass of the finished filter rod, the mass in this case being additively composed of the acetate mass and the amount of triacetin applied.
- the triacetine content is determined in accordance with the offline methods already described above. The method is already suitable with restrictions for regulating the total mass of the filter rods, but with the restriction that the density determination by means of beta emitters cannot detect moisture fluctuations in the measured material.
- the amount of acetate introduced is determined by positioning the filter tow bale on a balance and continuously recording the consumption of material during the manufacturing process. When the number of cuts (filter rod sections) per unit of time is determined at the same time, a combination of these two measured variables can be used to infer the amount of acetate used per filter rod. If the final weight of the filter rods is also determined by external weighing, the difference between the material used and the actual filter rod mass results in the amount of triacetin applied.
- This method also has the disadvantage that it can only be described to a limited extent as an on-line method, since it requires an additional off-line weight determination of the finished filter rods.
- the frequency of the triacetin values obtainable by this method is determined by the frequency of the externally determined gross weight determinations. Since filter rods have to be removed from the product flow for this purpose, this determination is also associated with a non-negligible amount of waste.
- the balance also has the disadvantage that disturbances which occur due to certain tow defects cannot be detected. One of these disturbing factors would be, for example, the failure of a spinneret during the manufacturing process of the filter tow, with the effect that 2 to 5% of the nominal total titre is missing for a short time. Ultimately, this means that with the same amount of consumption, measured by the weight loss of the bale, the filter rods become about 2.5% lighter. As a result, this would simulate a low triacetin content. In addition, short-term fluctuations in both the amount of acetate and the amount of triacetin cannot be determined using this method.
- Another disadvantage of this method is that the moisture of the acetate is not taken into account when determining the amount of acetate.
- the equilibrium moisture content of cellulose acetate under normal conditions is about 5.5% by weight.
- the initial moisture of a filter tow can vary between about 3.5 and 7% by weight due to changed process parameters in filter tow production. This variation leads to a relative inaccuracy in the mentioned weight determinations for the amount of triacetin and acetate.
- the final moisture, and thus the gross weight of the finished filter rods can also be significantly influenced by changing process parameters during filter rod production. Examples include parameters such as the indoor climate, the processing speed and the temperature and humidity of the air at the spreader nozzles.
- the present invention is based on the object of eliminating the disadvantages of the prior art discussed above and of describing a device for the simultaneous, continuous measurement of the acetate and triacetin mass and the regulation of the production process.
- the device according to the invention for the production of cigarette filters with simultaneous regulation of the filter material and plasticizer mass, comprising a processing part AF for processing the supplied filter tow, a format device F for forming a covered filter strand and a metering device integrated in the processing part for metering in plasticizer characterized in that sensors for detecting the mass flow of filter tow material Mi and sensors for detecting the sum of the mass flow of filter tow material and plasticizer mass M2 are present in the device, the device containing a measuring and control device which is compatible with the Sensors for measuring the mass flows Mi and M2 is coupled such that both the filter material and the plasticizer mass can be measured and controlled independently of one another.
- Sv2 can be arranged at various points in the overall device, it being essential for the invention that, viewed in each case in the running speed of the filter train, the sensors indicated with "1" are located in front of the metering device and the sensors indicated with "2" behind the same.
- the first mass sensor Smi and speed Svi can therefore be located anywhere between the bale drain and the
- the sensor Svi for detecting the speed vi and the sensor Smi for detecting the length-related mass mi are arranged immediately adjacent.
- “Immediately adjacent” is to be understood to mean that they are located one behind the other in the direction of the course of the filter strand, without another element of the device being located between them. If the sensors work without contact, it may also be possible to measure at the same point. This ensures that the speed and length-related mass are recorded at a point on the filter strand at which identical overall conditions with regard to the drawing state of the filter tow prevail.
- the senor Sm2 viewed in the direction of travel of the filter strand, is arranged directly in front of the cutting device, and the measuring device for the format tape speed is used as the sensor Sv2.
- the speeds vi and V2 are preferably detected via optical sensors.
- optical sensors have the advantage that the measurement of the relative speed between two objects can take place without contact. As a result, there is no mechanical intervention in the course of the filter train due to the measurement.
- the surface structures of the filter strand are usually imaged on a grid, where they generate light modulation. With the help of a photoelectric component, this light modulation is converted into a frequency proportional to the relative speed.
- Other ways to Non-contact measurement of the speed of a continuous strand of material can be used, but are not mentioned here.
- any sensors can be used as "mass sensors” with which it is possible to directly or indirectly measure the length-related mass of a continuous strand of material.
- the moisture content of the material to be measured can be determined simultaneously and independently of the mass determination, since this is the only way to determine a complete mass balance during the processing process (moisture, acetate - triacetin mass).
- the length-related masses mi and rr are therefore preferably determined with the aid of microwave resonators as mass sensors.
- EP 0 468 023 B1 explains how the length-related mass and the moisture of a product located in the microwave field of a microwave resonator can be determined independently of one another by measuring two physical effects.
- microwave resonators form a standing wave through which the acetate or filter material to be measured is moved with the aid of special openings and product guides lined with dielectric material.
- the special interaction between the standing microwave and the product changes the resonance properties of the microwave resonators.
- a great advantage of these resonators is that one can adapt to a wide variety of applications by means of a geometrical design and thus achieve a large measuring effect and a great depth of penetration into the product.
- This "fork resonator” is a resonator excited in the basic mode Eoio, which has been cut open in the direction of the wall currents, so that a measuring zone with an extremely homogeneous measuring field results.
- a planar sensor with a standing wave above a planar surface whose stray field decreases exponentially from the sensor surface into the room up to a maximum extension of 10 cm, is also suitable for a lateral one-sided measurement of the acetate strand before the plasticizer is applied.
- Such a sensor is described in EP 0 908 718.
- the profile sensor is particularly suitable, with which in particular a high spatial resolution of less than 3mm in the direction of the filter strand can be achieved, and which is also very suitable for measuring the homogeneity of the plasticizer application is.
- a profile sensor is disclosed, for example, in EP 0 889 321.
- This sensor has a through hole perpendicular to its areal extent. The through hole is delimited by metallic, longitudinally extending walls and is essentially flat.
- This resonator is preferably filled with a dielectric. Its thickness is much smaller than its length, that is smaller than the transverse dimension perpendicular to the thickness.
- the particular advantages of a microwave sensor with regard to the advantageous embodiment according to claim 8 will be explained again in more detail here.
- two quantities are the direct measurement variables: the change in the resonance frequency A and the increase in the half-width B of the resonance curve compared to the empty state of the resonator.
- the first effect of the resonance frequency detuning A mainly depends on the shortening of the wavelength due to the dielectric product which is currently in the measuring field of the resonator (i.e. on the so-called real part of the dielectric constant).
- the second effect B results from the conversion of the microwave energy into heat, which can only be measured precisely in the resonator method (the "microwave oven effect" or the so-called imaginary part of the dielectric constant).
- both quantities are equally proportional to the mass of the Products are in the measuring field, they are both suitable for mass measurement.
- parameter A is used for this.
- both measured variables are dependent on moisture in different ways. So the quotient of both variables B / A provides a mass - independent, This parameter can be used to compensate for the influence of moisture on the mass value A, so that two independent measured variables can be output: The moisture independent of the mass and that independent of the moisture
- the moisture information of the can shrink the acetate strands are used to compensate for moisture fluctuations between different acetate bales as well as within the bale by regulating the mass flow.
- a great advantage of the microwave measuring method is the constancy of the calibration once carried out, and its independence from fluctuations in material parameters, such as the change in the production parameters of the acetate, for example its total titer or its thread size.
- the measuring technique has recently been optimized to achieve a high measuring speed and precision, so that a new moisture and mass value can be output after 0.1 milliseconds, ie 10,000 values per second.
- a density measurement can also be carried out using beta radiation.
- an optical sensor can also be used as the mass sensor, in which the density is detected by means of scattered light measurements with infrared radiation.
- the mass flow Mi can also be determined by means of a bale scale according to DE 31 49 670 AI, the restrictions mentioned above relating to the moisture balance applying.
- the output signals of all sensors are either fed to a control device and / or a display device. If a control device is present, the process carried out with the device according to the invention can be controlled automatically, which proves to be particularly advantageous under production conditions. As an alternative to this, it is also possible for an operator to detect the signals displayed on the display device himself and to carry out the corresponding control. If both of the devices mentioned are present, the automatic control can be checked via the display device.
- control device is coupled to the drive of the processing part (AF) and the gear pump, which supplies the metering device with the required amount of triacetin.
- the filter tow fed to the filter rod machine is drawn off from a bale 8 and introduced from there into the processing device (AF) via a so-called gallows 9.
- the sensors Svi and Smi are arranged side by side in the order.
- the conditioning device generally comprises two spreader nozzles 3 and 3 ', a pair of brake rollers 1, by means of which the filter strand is pre-stretched, and pair of stretching rollers 2, which run at different speeds and subject the filter strand to stretching.
- the stretching rollers can be provided with a thread-like surface, so that only parts of the extended continuous filter strand are grasped and stretched. In this way, the individual filament groups that make up the filter strand are shifted against each other.
- the processing device has at its outlet a pair of deflecting rollers 5, by means of which the processed filter strand is deflected in a direction that is suitable for entry into the inlet nozzle and the inlet finger of the downstream format device F.
- the stretching rollers 2 and the deflection roller 5 are driven rollers which are operated at a fixed speed ratio to one another.
- the filter strand is gathered to the diameter of the future cigarette filter, coated with paper, and the filter rods are then cut to the required length in a cutting device 7.
- the sensor Sm2 is arranged directly in front of the cutting device 7.
- a conveyor belt for the filter strand is a textile belt, known as a format belt, which wraps the filter strand tightly during the gluing process.
- the speed of this means of transport corresponds to the speed of the filter strand in the format part and thus after the metering device 4. This speed is measured by means of the sensor Sv2.
- the metering of the acetate mass takes place in the filter rod machines according to the prior art by changing the speed difference between the preparation part (AF) and the format part (F), with that of the format part (F) generally being kept constant.
- the acetate mass can also be changed by other measures.
- EP 0 629 356 B1 describes the regulation of the acetate mass by changing the brake roller pressure on the brake roller pair 1.
- the metering device 4 is preferably arranged between the stretching rollers and the deflecting rollers in the processing device.
- the application of the plasticizer thus takes place on the completely spread out filter strand.
- the metering device usually consists of a spray box in which, for example, rotating brushes are attached, which serve to atomize the plasticizer finely and to spin it onto the spread fiber strand.
- Triacetin or TEGDA triethylene glycol diaceate
- the amount of plasticizer required for the process is usually supplied to the metering device 4 by means of a gear pump.
- the amount of plasticizer is dosed by changing the speed of the drive of this gear pump.
- the mass flow of filter tow material is constant at all points in the device.
- W is the amount of plasticizer in mg per filter rod
- K and C are factors that are determined by calibration. These calibration factors are quantities that result from the sensor characteristics.
- This calibration makes it possible not only to regulate the plasticizer content per filter rod, but also to measure it quantitatively and continuously, regardless of the filter tow specification used.
- Ki and Ci in turn must be determined by calibration according to the sensor characteristics.
- a control implemented with the device according to the invention is to be carried out so that the products Mi and M2 are kept constant.
- the speed of the processing section (AF) should be controlled so that the product Mi is returned to the original value.
- control In the event of a thread break (case 2), the control can also be designed, with some computation, so that not a constant acetate weight as the target variable but a constant draw resistance is achieved.
- This type of regulation presupposes that the dependency on tensile resistance, acetate weight and total titer is known.
- Such calculation models exist. One of them is sold by Rhodia Acetow under the name "Cable ® ".
