Capsule monitoring in filters for the tobacco processing industry

[0001] The invention relates to a method of monitoring the quality of supplying a filter or filter band in the tobacco processing industry with capsules that contain a liquid filling.

[0002] New cigarette products to be placed on the market have, as an important component of the filter, one or more capsules which is or which are filled with a liquid, for example menthol. Immediately before lighting a cigarette, the smoker opens the capsules by pushing on the filter, so that the liquid is released and the smell of liquid spreads. To guarantee this, it is necessary to guarantee the quality of the cigarette product. At the time of sale of the cigarette product, the capsule must be filled and must effortlessly occupy the optimal position in the filter.

[0003] WO 2009/099793 A2 discloses a system and method for analyzing a filter element. The sensor element determines the state of the object introduction, which provides for the recognition of at least the presence of the filter element, the absence of the filter element, the correct insertion of the object into the filter element, the incorrect insertion of the object into the filter element, the correct object in the filter element or the incorrect object in the element a filter.

[0004] EP 2 207 027 A2 (technique stand according to article 54 (3) KPE) shows a method and apparatus for measuring mass and density and / or for measuring humidity in the case of a large number of portioned units in a non-metallic support material. A microwave meter consisting of a microwave resonator for producing a mode or resonance mode in a locally limited measuring range and an analysis unit for analyzing at least one size of the operating mode or resonant mode are provided. The microwave meter measures this at least one resonant mode quantity when only the carrier material without portioned units is present in the measuring range and when the portioned unit is at least partly in the measuring range. The analyzing unit subtracts the measured value for the carrier material from the measured value for the portioned unit and determines the value for humidity and / or for the mass or density of the portioned unit based on the difference.

[0005] The object of the present invention is to guarantee a high quality cigarette product in which at least one capsule is present in the filter which is filled with liquid.

[0006] The solution to this task is the subject of claim 1.

[0007] The microwave measurement method is used to monitor the quality of a large number of filters or a filter band in the tobacco processing industry into which or into which liquid-filled capsules are incorporated. [0008] Using the microwave measuring method, the quality of the filters produced or the filter band produced with the capsules introduced can be very closely monitored.

[0009] Quality monitoring may relate to the number of capsules, the position of the capsules and / or the condition of the capsules. In the case of the number of capsules, it is determined during quality supervision whether the correct number of capsules has been entered correctly or whether one capsule is missing or too many capsules inserted or no capsule inserted at all. With regard to the position of the capsule, it is checked in particular that the capsule is positioned in the correct position towards the longitudinal axis of the band or filter. By checking the condition of the capsules, it is determined whether the capsule is completely filled or only partially filled, whether the capsule is empty or if liquid has leaked out. In this case, when liquid has leaked out of the capsule, the liquid is suitably distributed in the filter band or in the filter, which can be very easily determined, especially by means of a microwave measurement or microwave measurement method. The quality supervision also includes checking that the correct capsule has been inserted, and for example instead of menthol filling, another filling can be provided, which can also be determined in particular by means of the microwave measurement method.

[0010] For example, the position of the capsules in the filter band or filters is regulated. For this purpose, for example, the position of the capsules is measured and compared with the set position. In the event of a deviation from the set position, a corresponding control signal is sent to the capsule insertion device into the filter band, which causes, for example, that the phase of the insertion device is changed, e.g. by inserting the capsules into the filter band for a short time or more slowly .

[0011] The task is to supervise the quality of supplying the filter or filter band in the tobacco processing industry with capsules that contain a liquid filling, wherein the filter or the filter band is passed through the microwave measuring field of the microwave resonator and wherein at a given operating frequency the change in the microwave field in the microwave resonator is measured and the quality of supplying the filter with capsules and / or the quality of capsules introduced into the filter is determined on the basis of this change. to the filter band. In the context of the invention, supplying is understood to mean, in particular, inserting capsules into a filter or into a filter band.

[0012] Especially preferably a microwave resonator is used, which is described in DE 198 54 550 B4 and has the resonator housing mentioned therein.

[0013] The operating frequency is in the range of 2 to 30 GHz, in particular the operating frequency is preferably in the range of 2 to 10 GHz, particularly preferably between 5 and 6.5 GHz. Preferably, the operating frequency lies within the rising or falling edge of the measuring intensity curve depending on the frequency. Such a curve can be obtained by introducing a tunable frequency of microwaves into the microwave resonator and measuring the resulting measuring current or the intensity of the signal of the collected or output microwave which has been taken or output from the microwave resonator. A curve is then created, as shown in figure 6. Within the scope of the invention, the concept of measuring intensity or signal strength also includes the concept of amplitude.

[0014] The operating frequency is then located not at the maximum of this frequency waveform, but on a slope. This allows you to determine the frequency changes more clearly. In addition, such a single-point measurement, i.e. a measurement at one frequency, has a very high processing speed.

[0015] The measurement is then carried out so that a microwave at a frequency that corresponds to the operating frequency is introduced into the microwave resonator coupled to the microwave resonator and the corresponding signal of the collected or output microwave (decoupled microwave) is measured. Preferably, only the measuring intensity or amplitude or additionally the slope can be measured at operating frequency, so that more accurate information about the quality of the inserted capsules can be given. The slope is for example the slope of the measured frequency waveform at the operating frequency or the signal change over time. Preferably, the change is therefore a change in the microwave field signal and / or a change in the slope of the microwave field signal at operating frequency.

[0016] Preferably, the change is dependent on time and / or place. By this is meant in particular that a moving filter band or a moving filter is measured, so that changes in the microwave field occur as a result of changing measurement conditions over time, or with respect to the band or filter, the change occurs in the direction of the longitudinal axis depending on the place.

[0017] Preferably, the number, position and / or state of the capsules is determined.

[0018] Preferably, by checking the condition of the capsules, it is determined whether the capsules are completely filled, partially filled, empty and / or that liquid has leaked from them and / or if these are required capsules.

[0019] Preferably, the method is carried out in a filter band making machine in the tobacco processing industry and / or in a filter transfer line in the tobacco processing industry. As for the implementation of this method in the filter transfer line, we refer to the patent application entitled "Verfahren und Vorrichtung zur ^ erp ^ fung der Qualitat von mit Kapseln versehenen Filterstaben" (Method and device for checking the quality of filter bars equipped with capsules) filed at the German Patent Office and Trademarks the same day as this patent application.

[0020] A method of operating a machine for the production of filter bands in the tobacco processing industry has also been proposed, with capsules being filled with liquid being introduced through the insertion device into the filter bands, and the filters being cut to length using a filter device , wherein the phase between the insertion device and the cutting device or wherein the speed of the formatting tape is adjusted relative to the phase of the cutting device.

In the context of the present invention, the term phase between the insertion device and cutting device means the distance inserted by the insertion device from the cutting of the cutting device, in particular in relation to the filter produced, or the time dependence of the moment of insertion of the capsule by the insertion device and the moment of cutting the filter band by cutting device. The phase is preferably a multiple of the number of filters that are cut to length from the filter band by the cutting device and which enter the filter band section between the cutting device and the insertion device. The term phase between the insertion device and cutting device is also understood in particular to the difference in the rotation angle of the insertion device relative to the rotation angle of the cutting device.

[0022] The speed of the formatting tape needs to be adjusted, for example, when, when the formatting tape is worn, the strip of wrapping material located on the formatting tape slides relative to the formatting tape. In this case, the speed needs to be adjusted so that it is harmonized with the cutting device phase so that the cuts through the filter band are made in the right place.

Preferably, for adjusting the phase, the distance of at least one capsule relative to the cut made by the cutting device in the cutting position is determined, the distance of the cutting position relative to the at least one capsule is adjusted. Preferably, an average value of the cutting position distance from this at least one capsule is created and the phase is adjusted to this average value. This can, for example, be counteracted by the slowly starting slippage in the band production machine, for example between the formatting tape and the filtering band.

[0024] A filter band production machine has also been proposed in the tobacco processing industry with a formatting device for forming a filter band along an axis, wherein an insertion device is provided in front of the formatting device which introduces liquid filled capsules into the filter band and after the device formatting device cutting, which is cut from the filter band to the length of the filter, characterized by that a phase regulator is provided for adjusting the phase between the cutting device and the insertion device or the phase of the cutting device relative to the speed of the formatting tape.

[0025] Preferably a microwave measuring device is provided with which the position of the inserted capsule can be determined relative to a given cut. Preferably, the microwave measuring device comprises a resonator housing through which the filter band passes. Furthermore, the microwave measuring device is preferably used to determine the quality of the capsules introduced into the band. Preferably, a segregation system is also provided for defective filters, which then rejects cut-length single or multiple use length filters when, for example, the inserted capsules are defective, such as those from which the fluid has leaked, empty, only half-filled or are in the wrong position, or the number of capsules is incorrect, for example there is no capsule in the cut-length filter.

[0026] Preferably the filter band making machine is a multi-band machine, especially a two-band machine. Preferably, the adjustment of the position of the capsules between the insertion device and the cutting device is carried out in particular by correspondingly one microwave measuring device per band. Advantageously, the position of the capsules of the two filter bands or several filter bands relative to each other can also be adjusted so that preferably only one cutting device is needed for two or several filter bands. Alternatively, it is also possible to plan for one cutting device for each filter band, which are then adjusted separately in terms of their phase.

[0027] Without limiting the general idea of ​​the invention, the invention will be described below on the basis of exemplary embodiments with reference to the drawings, with reference to all the details not explained in detail in the text according to the invention being clearly referred to in the drawings. The figures show:

Fig. 1 schematic top view of a filter band production machine with filter cable pretreatment system, Fig. 2 measuring curves on two filters respectively, which are next to each other and each has a quadruple usable length, Fig. 3 measuring curves on two respectively filters, which are located next to each other and have, each of them quadruple usable length, fig. 4 measuring curves on respectively two filters, which are located next to each other and have, each of them quadruple usable length, Fig. 5 measuring curves on respectively two filters, which are located next to each other and each has four usable length, Fig. 6 schematic diagram of the amplitude depending on the frequency for two different fillings of the microwave measuring device, Fig. 7 schematic diagram of the frequency-dependent amplitude for two different fillings of the microwave measuring device, Fig. 8 schematic representation of a part of the filter band manufacturing machine according to the invention, fig. 9 schematic representation of a part of the next filter band manufacturing machine according to the invention and fig. 10 , three-dimensional representation of parts of another machine for producing the filter band.

[0028] In the figures below, the same or the same type of elements or corresponding parts have been designated with the same reference numerals in each case, therefore the corresponding repositioning is removed. [0029] Figure 1 is a schematic top view of a filter cable pretreatment assembly 120 and a filter band making machine 140. It is a system in which the pretreatment assembly 120 and the machine 140 for producing the filter band are arranged approximately in line with each other. In the pretreatment assembly 120, the filter cable web 61, after being unwound from the filter cable bale 110, is stretched, spread, and sprayed with plasticizer droplets, e.g., triacetin, so that the surfaces of the threads or fibers of the material web are partially dissolved and therefore stick together. The pretreated material web 61 is then transported or transferred to a machine 140 for producing a filter band with the so-called inlet funnel 141 and the formatting device 53 or the formatting kit behind it.

[0030] Between the inlet funnel 141 and the formatting device 53, a insertion wheel 42 is schematically shown which respective capsules filled with liquid, for example menthol, are introduced into the web 61 of material on the filter cable. This occurs in the area where the filter material web 61 rests on the formatting tape 52. Behind the formatting device 53, which forms the filter band 40 from the filter cable web 61, a microwave resonator 45 is provided through which the band is passed. In the microwave resonator 45, the quality of the filter band 40 is checked, e.g. whether the correct number of capsules exists in the filter band, whether they are in the correct position and / or whether the capsules are in order, i.e. for example that no liquid has leaked out of them and whether they are completely filled and / or these are the right capsules.

[0031] Behind it is a cutting device 46, which cuts the length of filters 41 from the filter band. Filters 41 usually have a multiple usable length. If it results from the quality control of a given filter 41 by the microwave resonator 45 that the quality does not match the set values ​​there, the respective filters 41 can be sorted using the exhaust device 51.

[0032] Figure 2 shows a schematic diagram in which the measuring current 10 is in arbitrary units plotted on measure 11. First, the measuring signal for the correct filling of two adjacent filters with a quadruple useful length has been measured. Each single-use filter at the time contained one capsule. In the case of correctly filled filters, it is then located approximately at bar 20, at bar 65, at bar 115, at bar 155 etc. Instead of the specified bars, time-dependent cut-off or place-dependent cut-off can also be applied. In the case of a time-dependent cut-off, it can be given, for example, in seconds or milliseconds. The position of each maxima in the measuring signal then depends on the speed at which the two filter bars located next to each other are led through the resonator. This should naturally take place at a constant speed.

[0033] Furthermore, in Figure 2 a measuring signal 13 is also shown for the two missing capsules, the position of the missing capsules is indicated by references 14 and 14 '. It can be clearly seen that the measuring signal 12 for correct filling differs clearly from the measuring signal 13 for the two missing capsules.

[0034] Figure 3 shows a corresponding schematic representation, also here for comparison the measurement signal 12 for correct filling is given and where in the case of the next measurement signal 15 it is seen in the case of incorrectly positioned capsules that at least four capsules have been measured wrong position. They are marked with references 16 to 16 '".

[0035] Figure 4 also shows a corresponding measuring diagram in which, first, a measuring signal 12 for correct filling is shown and, furthermore, a measuring signal 17 for an incorrect number of capsules. In the left filter with a quadruple usable length, namely, five capsules are introduced, the positions of these five capsules are indicated by reference number 18, respectively. The right filter with a quadruple usable length shows that the position of the appropriate capsules is also not correct for each capsule.

[0036] Figure 5 also schematically shows a suitable measuring diagram in which, in addition to the measuring signal 12 for the correct filling 12, the measuring signal 19 for the capsules from which the fluid has leaked is also shown. At positions 20 and 20 ', the capsules leaked fluid, respectively. This can also be seen from the clearly smaller measuring signal and also from the extended measuring signal. Based on the width, it can be said very precisely that the capsules leaked liquid. [0037] Figure 6 schematically shows a measurement intensity diagram in any units 10 depending on the frequency 21. Two frequency waveforms are shown, namely the first frequency waveform 22 and the second frequency waveform 23. These frequency waveforms arise at different levels of the corresponding microwave resonators.

[0038] Frequency waveform 22 may dominate, for example, when only the filter cable is located in the measurement range of the microwave resonator, and second frequency waveform 22, when the appropriate liquid-filled capsule is placed in the measurement range of the microwave resonator. At operating frequency 26, the amplitude or measuring current 10, respectively, is measured.

[0039] For the first frequency waveform 22, i.e. filling the microwave resonator with a filter cable, the measuring intensity or signal 27 is measured for the first frequency waveform, and when filled with a suitable capsule, the second measuring intensity or signal 28 for the second frequency waveform is measured. This is the most simple and fastest case of the analysis according to the invention, with the corresponding measuring curves measuring amplitude or measuring intensity at a constant frequency.

[0040] Depending on the properties of the band, especially the capsule filling, the size of the amplitude changes. For this reason, no resonance curve and no change in the resonance frequency or change in the width of the resonance curve are recorded, which would result in increased cost of measurement and very costly analyzes, but only the amplitude, and thus the measurement intensity at the operating frequency.

[0041] Alternatively, a frequency-modulated signal can also be introduced into the microwave resonator, so that in addition to the amplitude or measuring current 10, an amplitude change or slope or amplitude increase at operating frequency can be used in addition to the analysis. This is schematically shown in Figure 7. This allows additional measurement resolution to be obtained in critical cases. If, for example, it were to be as shown in Figure 7, that in the case of various filter components, the measuring intensity at operating frequency 26 does not differ, as at operating frequency 26 is shown in the case of the third frequency waveform 24 and in the case of the fourth frequency waveform 26, where for both frequency waveforms one signal 29 is obtained for the third and fourth frequency waveforms. Alternatively, the necessary information can be obtained from slope 30 for the third frequency waveform and slope 31 for the fourth frequency waveform at operating frequency 26. The operating frequency 26 in this case is about 5.8 GHz. The maximum signal strength or measuring intensity of the third 24-wave frequency falls at 6 GHz.

[0042] Figure 8 schematically shows a part of the filter band manufacturing machine according to the invention. The filter band 40 is transported along the longitudinal axis 57, and thus longitudinally axially, in figure 8 from right to left. In this embodiment, using the insertion wheel 42, two capsules 43 and 44 are introduced or inserted into the filter band 40, each at substantially equidistant intervals from two successive capsules 43 and 44. The filter band 40 then comprises side-by-side capsules 43 and 44 between which a somewhat further filter cable may be arranged. [0043] The filter band 40, filled with capsules 43 and 44, then runs through the microwave resonator 45, in which, among other things, the quality of the filter band and filling of the capsules 43 and 44 are checked. In addition, the microwave resonator 45 is used to determine the position of the capsules 43 and 44. The cutting device 46, which in this case is made in the form of a rotating knife support, then cuts the strand 40 into double-length filters 41. If it is determined in the microwave resonator 45 that the quality of the double length filter bars 41 produced is not correct, they are blown out by the blowing device 51.

[0044] The control and adjustment of the respective components of the filter band making machine 60 are as follows:

The rotation speed of the insert wheel 42 is controlled by the synchronized or phase-controlled drive system 47. This system sends the appropriate control signal to the insert wheel or to the insert wheel actuator 42. Each insert rotation position is transmitted as actual position back to the drive system 47 which the system 48 position control provides the actual phase value. The phase setpoint is transmitted by the position control system 48 to the drive system 47. This is indicated by the appropriate lines with arrows that connect the respective components in figure 8.

[0045] Furthermore, the microwave resonator 45 transmits the actual position of the capsules 43 and 44 inserted into the band 40 to both position control system 48 and quality control system and statistics 50. In the event of an incorrect position, the quality monitoring system and statistics 50 are used to send an ejection signal to the blowing device 51, so that the corresponding filters 41 with the incorrect position capsules 43 or 44 are blown out.

[0046] In addition, the position control system 48 sends the phase setpoint for the knife carrier 46 to the phase synchronized drive system 49. The actual phase value is transmitted back to the position control system 48 by the drive system 49. The knife carrier or knife carrier actuator 46 is properly connected to the drive system 47.

[0047] In an ideal and error-free production, the insert wheel 42 for capsules 43, 44 and the knife support 46 are adjusted once correctly in terms of their phase position in such a way that the cutting takes place at the desired place in relation to the capsules. As a result of the wear of the formatting tape, which is also shown in Figure 9 or Figure 1, for example, slowly starting to slip between the filter band 40 and the formatting tape 52 during production. The result is a slow systematic escaping of the capsules relative to the intersection of the filters 41. This problem can be solved by the fact that in the case of systematic escaping of the capsules, the phase position between the insertion wheel 52 and the knife carrier 46 is additionally adjusted by the cutting position control system or system 48 position adjustment.

[0048] Figure 9 shows another schematic embodiment of the machine 60 for producing a filter band according to the invention. The components: insertion wheel 42, microwave resonator 45 and cutting device 46 are also properly represented. Insertion wheel 42 has cavities in which in each embodiment only one capsule 43 is inserted. This is in contrast to the embodiment of figure 8, in which respectively double cavities are provided, in which two different or the same capsules are inserted side by side. The capsules are appropriately held, for example by aspiration air, until they are passed to the band 41.

[0049] A formatting device 53 is shown in figure 9 after the insertion wheel 42, which includes, inter alia, a formatting tape 52. The formatting device is also in the embodiment according to figure 8, but is not shown there.

[0050] The phase adjustment takes place depending on the measured position value of each capsule 43 each inserted into the band 40, which value is generated by the microwave resonator 45 and is fed to the phase regulator 55. The phase regulator 55 so controls or regulates the phases of the insert wheel 42 relative to the cutting device 46 so that the correct cutting position 54 can always be maintained which lies at a given distance from the inserted capsule 43.

[0051] Figure 10 shows schematically and three-dimensionally a part of the filter band manufacturing machine according to the invention in a further embodiment. A two-band machine is shown, a machine for producing filter bands for processing two 40 and 40 'filter bands. Accordingly, two insertion wheels 42, 42 'are provided, each of which is driven by a respective drive system 47, 47'. Also in this case, the insertion wheels 42, 42 'serve to insert the capsules 43 into the filter bands 40, 40'.

[0052] In addition, a bobbin is shown, from which the wrapping material 62, 62 'is unwound after cutting. Wrapping material 62, 62 'is fed into two formatting tapes 52, 52'. Formatting tapes 52, 52 'are driven by 64, 64' drive systems. The filter bands 40, 40 'are applied to the formatting tapes 52, 52' and guided by the formatting devices 53, 53 ', in which the strips 62, 62' of wrapping material are wrapped around the filter bands and also closed. [0053] Then follows a device 63 for smoothing a weld, in which, especially under the action of heat, the welds of the wrapping material strips or adhesive for closing the welds are dried. The 40, 40 'bands then pass through a 45' microwave resonator, which has two through holes, one for each 40, 40 'bands. The 45 'microwave resonator can be a microwave measuring device that consists of two microwave resonators decoupled from each other. Especially thanks to the decoupling, very good measurement accuracy for a given band is possible. As a result, the method of supervising the quality of supplying one filter or a given filter band in the tobacco processing industry with capsules that contain a liquid filling can be implemented in a given band.

[0054] Behind the microwave resonator 45 or microwave resonator device 45 are two cutting devices 46, 46 'which are driven by drive systems 49 and 49' respectively.

[0055] The adjustment of the position of the respective driven components, namely insertion wheels 42, 42 ', format tapes 52 and 52' as well as cutting device 46 and 46 'is carried out by respective drive systems 47, 47'; 64, 64 'and 49, 49' connected to these components. Adjusting the position of the formatting tapes 52 and 52 'includes, in particular, speed control.

[0056] The position control system 48 receives from the microwave resonator 45 'the position of the given capsules 43 in the given bands. This position is further processed into control variables that are used to drive the propulsion systems. In this way, the phase of the cutting devices 46, 46 'can be controlled and adjusted. Accordingly, the phase of the cutting devices 46, 46 'can be controlled or adjusted compared to the speed or speeds of the format tapes 52 and 52'. Finally, it is possible to control or adjust the phase of the insertion wheels 42, 42 'with respect to the speed of the formatting tapes 52 and 52'.

When this phase is referred to in the context of this application, it can instead also be understood as speed, especially rotational speed.

It is particularly advantageous when the position of the capsules 43 inserted into the filter bands 40, 40 'is controlled or adjusted so that the capsules 40, 40' in the transport direction always lie at the same height relative to both bands 40, 40 '. In this case, the cutting devices 46 and 46 'can at the same time cut the strands and synchronization of the filter bands 40, 40' and further processing of the cut length filters takes place.

In the event that the cutting or rotational speed of the cutting device or cutting devices is a guide value of regulation or is constant, both strands may be cut with one cutting device.
