Description
The present invention relates to a kind of filter nozzle manufacturing method and a kind of filter tip manufacturing installation, be furnished with an applying device, be used for plasticizer is coated on the filter medium, also be furnished with a filter medium conveying device.
A kind of suitable filter nozzle manufacturing method and a kind of suitable filter tip manufacturing installation were for example disclosed in the EP of applicant 1106087 A2.Utilize described method of this patent and described device,, be droplets (droplet mist) and be coated on a kind of filter medium, for example on the filter medium made from cellulose acetate for example a kind of plasticizer of a kind of additive of liquid state such as triacetate.On filter medium, can realize plasticizer coating very uniformly.
In the filter tip manufacture process in principle some holes might appear once in a while in filter tip certainly, and promptly so-called " fusion hole ", this hole is because local too high plasticising dosage causes.Its reason for example may be that triacetate drips, and perhaps also may be the fiber that is soaked into by triacetate that carries.Those holes are to form by the chemical reaction with filter medium after production process, and after filter-tip material hardens fully and reach its final size.
Task of the present invention provides a kind of filter nozzle manufacturing method and a kind of filter tip manufacturing installation, so as to producing a kind of filter tip of homogeneous as far as possible.
This task is to solve by the filter nozzle manufacturing method with following processing step:
Filtering medium strip is provided,
On filter medium, apply plasticizer,
The filter tip dielectric rod that is shaped,
Isolate filter tip from filter stick, wherein, produce one at least along the signal relevant of filter medium throughput direction position resolution with plasticizer concentration, eliminate filter tip simultaneously, but but promptly this filter medium has been produced the signal that is lower than one first predetermined threshold value or is higher than one second predetermined threshold value with this filter medium.
According to the present invention, by at least along the measurement of the throughput direction position resolution of filter medium, the rod section with local unallowed plasticizer concentration of filter stick can be classified as a separated subsequently filter tip of opening, make this filter tip disallowable to go out, be not used further to for example production of cigarette.Preferably, signal to be created in perpendicular to the filter medium throughput direction also be position resolution, thereby can improve discrimination to so-called " fusion hole ".Within the scope of the invention, position resolution one speech also be can be understood as time resolution.
If temperature is measured for the generation of signal, the heat radiation of being sent by filter medium or filter stick is measured, perhaps the electromagnetic radiation by filter medium or filter stick or Ultrasonic attenuation and/or frequency variation are measured, just can be produced a reliable signal in a kind of very effective and safe mode.For this reason, for example can utilize an infrared light emitting diode to send infrared light, penetrable filter medium of this infrared light or filter stick, and reach an infrared receiver, the signal of telecommunication of this receiver is fed to a measuring unit.Variation in the signal to be measured all is attributable to the different light-transmitting capacities of filter stick then.Triacetate for example drips can improve light-transmitting capacity, thereby causes a kind of discernible signal skew.The filter stick that is flooded by triacetate or the filter medium of corresponding dipping are analyzed by measuring unit, and trackedly always remove valve to a throwing, a rejecting valve or general saying, and a waste product filter tip device for eliminating, and from production process, removed.Also can use visible light or microwave to replace the electromagnetic radiation of infrared radiation form.Also have a kind of possibility, produce a kind of nuclear spin resonance exactly and the gained result is measured.About the measurement of nuclear spin resonance, but REFERENCE TO RELATED people's EP1325683A2.
Especially effectively way is, temperature is measured, and perhaps the heat radiation of sending from filter medium or filter stick is measured.Because the coating of warmed-up plasticizer that is in a liquid state such as triacetate can cause producing higher heat radiation.The plasticizer of coating is many more, and heat radiation is just big more, thus by a kind of Temperature Distribution can correspondingly reflect filter medium or the rod made with filter medium in the amount of plasticizer.Preferably, only measure the heat radiation of plasticizer and the difference between reference value, thus draw filter medium by this way or the rod made with filter medium in the temperature profile of plasticising dosage.So just produce a demonstration that contrast property is strong of a temperature profile that for example forms by the temperature difference in filter medium or the filter medium rod.Like this, the fluctuation of the absolute temperature of filter tip medium, plasticizer and machine surrounding environment is all effectively compensated.Temperature profile can utilize a same specified distribution map of PaintShop to compare, then under the situation of a deviation that surpasses admissible error value or threshold value up or down, corresponding filter tip section or filter tip are made an electronics mark, rejected with being about to this filter tip.
Next processing step is exactly before the coating plasticizer filtering medium strip to be launched.If utilize at least two different measuring methods to produce at least two signals, just can improve to hole or discrimination that the plasticizer that causes producing the hole is later on dripped.
Preferably, signal produces after being coated to plasticizer on the filter medium and before filter stick forms.If signal produces, then can use the measuring method of utilizing electromagnetic radiation effectively after filter stick forms.Preferably, if signal produces, then might detect the hole that has produced on filter tip.
In addition, task of the present invention is solved by a kind of filter tip manufacturing installation, it is furnished with an applying device, be used for plasticizer is coated on the filter medium, also is furnished with a filter medium conveying device, wherein, also adopted a measurement mechanism that is used to produce signal, this signal can reflect a plasticizer concentration in the filter medium of position resolution in the filter medium throughput direction at least.
Preferably, measurement mechanism comprises: a temperature measuring equipment, heat radiation absorption plant and/or an electromagnetic radiation or ultrasonic dispensing device, and an electromagnetic radiation or ultrasonic receiving system.
In addition, also be equipped with a comparison means, compared with at least one first and/or one second predetermined threshold value but be used for this signal according to the present invention.Preferably, also be provided with a filter tip device for eliminating at last.
To be not limited to general inventive concept below, the present invention will be described according to several embodiment with reference to accompanying drawing, wherein, relates to the details of the present invention that all are not addressed in this article in detail, all can be with reference to the accompanying drawings shown in.Accompanying drawing is represented:
The diagrammatic side view of Fig. 1 filter tip manufacturing installation of the present invention.
The schematic plan view of a part of Fig. 2 filter tip manufacturing installation of the present invention shown in Figure 1.
Fig. 1 represents the diagrammatic side view of a kind of filter tip manufacturing installation 1 of the present invention.Be provided with a roller to 2, it is used for extracting the filter fiber band of for example making with cellulose acetate 3 of a no end continuously out from a bundle volume 4.Filter fiber band 3 after bundle volume 4 is extracted, be guided by slewing rollers 6 be sent to roller to 2 way in, be used to launch and loose filter fiber band 3 tissue fibers through two air nozzles 7 and 8 these two nozzles.Omitted among Fig. 2 above-mentioned in Fig. 1 visible parts.
After roller is to 2, two rollers are arranged in addition to 9 and 11 on the traffic direction 40 of filter fiber band 3, these two rollers between a conveying device 12 is arranged, it be used for a kind of additive with plasticizer form for example triacetate deliver on filter fiber band 3 fibr tissues of between roller is to 9 and 11, spreading out that are guided as flat band.Advantageously, roller to each roller of 9 and 11 with equal diameter in, roller is provided with the line of rabbet joint (fluting thereon) on its periphery, its symmetrical roller then can have the smooth surface made from elastomeric material.All rollers all can be driven through unshowned equally in the drawings belt drive unit by a unshowned in the drawings driver motor 2,9 and 11, as introducing in US-PS 5060664.The also configurable drive unit that separates replaces driver motor.
Roller to 2 rotating speed less than roller to 9 rotating speed, roller just forms a stretching device to filter fiber band 3 to 2 and 9 like this.Roller can be through gearbox 14 changes to 2 rotating speed, and the gear ratio of this gearbox can be come change by a controlled servomotor 16.Roller to 2 and roller to the speed between 9 than given go out filter fiber band 3, promptly by the level of stretch of the band of the formed expansion of this filter fiber band.In an illustrated embodiment, brake roller 2 is by transmission, and they also can be designed as driven voller and since its friction so play the effect of brake roller.
At (with respect to the traffic direction of filter fiber band 3) before the coating region 17 with a measurement mechanism 18 is arranged between roller is to 2 and 9, its be used to measure be unfolded with 3 density value.This measurement mechanism has telemetry transmitter 19a-19e, and these transmitters dispose respectively to a zone 3a-3e, and becomes a row ground to be arranged perpendicular to longitudinal extension and traffic direction 40 with 3.The effect of the telemetry transmitter 19a-19e of measurement mechanism 18 is to measure respectively the density value of band among the zone 3a-3e, so as to measuring its inhomogeneities.Telemetry transmitter 19a-19e has light source 21a-21e and photoelectric detector 22a-22e.A detector 22a-22e sends a signal, and this signal is relevant with the decay of penetrating light thereon.
If the course of conveying of the filter fiber band 3 that goes out from bundle volume 4 drawings, owing to making the density of a zone, any influence changes, perhaps this density deviates from a predetermined value, and then affiliated telemetry transmitter just demonstrates above-mentioned unwished-for running status with its signal.The signal of telemetry transmitter 19a-19e is flowed to a signal processing apparatus 23a-23e respectively, and this treating apparatus will be handled each signal, in case of necessity it same rated value is compared.The output signal for the treatment of apparatus 23a-23e is delivered to the 24a-24e of executing agency, and these executing agencies for example can realize the control to the amount of the additive (for example triacetate) that is supplied to by the variation of its flow cross.Each telemetry transmitter 19a-19e so controls the 24a-24e of executing agency under it, makes this executing agency hour reduce its flow cross in the density of measuring, thereby reduces to supply with additive from reservoir vessel 26; When the density of measuring is big, increase the supply additive thereby increase its flow cross.Like this, the quantity delivered of additive just can adapt to the density ratio, thereby always can keep the same ratio of filter fiber and additive in a zone 3a-3e.The total amount of the additive that certain filter tip strip length and certain filter fiber amount are supplied with can remain unchanged.
In the exit of valve 27a-27e nozzle 31a-31e is arranged, additive for example triacetate flows to filter tip band 3 by said nozzle with the atomised form 26a-26e of fine distribution, and is applied on its fiber.Additive can utilize one or more unshowned in the drawings pumps to flow to the 24a-24e of executing agency usually from reservoir vessel 26.
Another roller is to representing with 28, and processed/ready filtering medium strip 3 is from the feed hopper 29 of this roller to for example the applicant's of being fed to a known filter stick forming machine cigarette industry KDF model.In addition, for above-mentioned filter stick forming machine, a filter tip specification 35, the filter stick 32 that has been shaped also schematically are shown, are used to be syncopated as cutter 33 and a valve 42 of filter tip 34, the purposes of this valve is: the filter tip 34 that will not meet desired character is rejected away from later process.
The hole that at this moment might on filter stick, occur as mentioned above, so-called " fusion hole " occasionally.This hole is because the interference of instantaneity causes, and for example forms on nozzle 31a-31e that bigger additive drips and the sort of hole will occur when being applied on the filter-tip material 3.Some may produce this hole in several hrs after the filter tip manufacturing.In order to prevent that filter stick section or filter tip 34 with respective hole from further being processed on cigarette with filter tip, being injected to amount in the filter medium or that be coated in the plasticizer on the filter medium or concentration is in the present invention determined by corresponding measurement mechanism, but and surpassing a predetermined threshold value or when being lower than second threshold value that can be scheduled to, the filter tip section or the consequent filter tip 34 that relevance filtering mouth section are promptly produced this signal are thereon rejected.
For this reason, for example figure 1 illustrates different measurement mechanisms, but have only one or several to adopt.For example on the throughput direction 40 of filter medium, show a measurement mechanism 38a in coating region 17 back, 38b, wherein, measuring device part 38a sends electromagnetic radiation, measuring device part 38b then absorbs one plasticized dose and the altered radiation of filter medium, for example altered intensity or phase place.Here, measurement mechanism also can preferentially be a ultrasonic device for measuring, perhaps a nuclear spin resonance measurement device.
Above-mentioned measurement mechanism can obtain a measured value on the overall width of the filtering medium strip 3 that spreads out, but also can (not shown in FIG.) be with on 3, on the different detectors of settling side by side each other that send out electromagnetic radiation or ultrasonic device 38a and the above-mentioned radiation of corresponding a plurality of reception or a ultrasonic device 38b and a position resolution, obtain the position resolution signal perpendicular to throughput direction 40 ground.Corresponding position resolution also can utilize other measurement mechanism 36a, 36b and 37 to be realized, of course not definitely must so do.The signal that obtains from receiving system 38b is fed to comparison means 41, has stored a upper limit threshold and a lower threshold in this comparison means, and correspondingly above-mentioned signal has been compared with the upper limit and lower threshold in this device.The result decides on gained, sees just whether signal is in the scope between the upper and lower bound threshold value, and valve 42 is controlled by comparison means 41.Therefore, also control device and/or adjusting device of comparison means 41.
Be provided with another measurement mechanism 36 at last, it comprises a launcher of electromagnetic radiation 36a and an electromagnetic radiation receiver 36b, and its signal is fed to comparison means 41 as illustrated in fig. 2.On this position, promptly along throughput direction at a kind of infrared rays survey of filter tip specification 35 back particularly suitables, or a kind of measurement that utilizes visible light.On other position shown in corresponding measurement mechanism 36a, 36b, 37,38a and 38b also can be placed in beyond the position or transposition each other.
