German Patent Application No. 102006001643 International Application Publication No. 00/51451 Specification European Patent Application No. 13143363

  The object of the present invention is to further improve the supply of at least one additive to the filter tow strand for the production of a two-strand or multi-strand filter.

  The problem is that the supply device has at least two supply sections, each of which has at least one supply section built into the filter tow guide section to distribute the amount of additive supplied through the supply apparatus. And a distribution device for delivery to the attached filter toe guide section, comprising at least two filter tow guide sections, each of which is guided along the guide section, and the tobacco processing industry And an apparatus for processing at least two filter tow strands and a supply apparatus for supplying at least one particulate or powdered additive to the filter tow guide section for feeding to the filter tow strand.

  According to the present invention, one supply portion which is a part of the supply device is incorporated in one filter tow guide section, so that the supply of at least one additive to the filter tow strand is a two-strand or multi-strand filter. It is configured to be substantially flexible for manufacturing. This is because the present invention offers the possibility of separate supply of at least one additive for the filter tow strand. Thus, for example, different types, compositions and quality preparations of at least one additive are possible with respect to feed segments in different filter tow sections. The same applies for the amount of the at least one additive, which can be selected and adjusted differently for the individual filter tow sections according to the arrangement of the invention, for which according to the invention an additional dispensing device is added. Provided. The present invention therefore offers the possibility of supplying a certain amount of additive to the filter tow strand.

  Preferred embodiments and reproduction aspects of the invention are given in the dependent claims.

  According to a preferred embodiment of the invention, the distribution device has at least two distribution means, one of which is incorporated in the filter tow section. In the reproduction mode of this embodiment, at least one dispensing means has at least one dispensing roller. Therefore, in this embodiment, the possibility arises not only of a separate additive supply, but also of a separate distribution for different filter tow strands.

  Preferably, the supply section has at least one reservoir for intermediate supply of at least one additive. Furthermore, in particular, the supply section has at least one shaft that feeds the distribution device. Therefore, the two reservoirs are filled with different additives, the additives reach the distributor in the shaft, which distributes a certain amount of additive to the filter tow section and thereby the filter tow strand. Delivered to

  In another preferred embodiment of the invention, a turning device is provided to turn the filter tow section into an array located substantially overlapping. In the region where the filter tow strands are located substantially overlapping, the filter tow strands are sprinkled with additives by means of a dispensing device, whereby a simultaneous application of at least one additive is achieved in a particularly simple manner. In this case, the filter tow strands are displaced from each other. In this embodiment, merging from the aligned alignment of filter tow strands is costly and is omitted.

  Another preferred embodiment of the invention is that the dispensing device is configured to deliver the additive on the filter tow strand in a strip section, the strip section being at an angle of less than 90 ° with respect to the direction of movement of the filter tow strand. It is arranged. Preferably, at least one distribution roller is arranged at an angle of less than 90 ° with respect to the direction of movement of the filter tow strand at its axis of rotation. In this connection, for good integrity, it is sharper than the measured value that the same tilt state is assumed to be achieved even at an angle greater than 90 ° with respect to the direction of movement of the filter tow strand. This is because it is geometrically the same whether an angle or an adjacent blunt angle is used. In this embodiment, the coating process is performed lengthwise (longitudinal) at the length extension of the filter toe strand, so that the additive to the filter tow strand of the additive depends on the inclination of the filter tow strand with respect to the dispensing device and in particular to the dispensing roller. Uniform distribution can be achieved. This embodiment is in particular the case of the use of a distribution roller which is formed as a groove roller, because the distribution process takes place from the individual groove depressions to the length in the strand direction due to the inclined state.

  Another preferred embodiment of the present invention comprises first turning means for turning at least two filter toe guide sections from a substantially overlapping arrangement into one mutually branched alignment and one aligned from the mutually branched alignment. And a second turning means for turning the filter toe guide section in an array located at a position, wherein one turning means is incorporated in the filter tow guide section from the first turning means, and the second turning means. Similarly, one turning means is incorporated in the filter toe guide section. In particular, the first turning means are oblique to each other. This oblique state generates a substantially constant tensile stress over the entire width of the filter tow strand. In the reproduction mode, the second turning means are formed so as to provide an alignment that converges from these turned filter tow guide sections. Thereby, the center lines of the filter tow strands are merged in a simple manner without generating tensile stress on one side. Subsequently, the filter tow guide section runs side by side to the distributor, where the additive is applied to the filter tow strand.

  Next, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

  In the figure, the schematic functional components according to the invention, the structural elements, the device members and the devices containing them evaluate the filter tow strands in order to produce a filter for rod-like smoking articles, in particular cigarettes, in a strand method. In the drawings, each of the drawings substantially shows components and components necessary for an understanding of the present invention. In the mechanical structure, the usual components of the machine or device, such as the machine cradle, the holding body, the bearings and the details of the exterior, are not generally shown in the drawings for better visibility.

  The embodiment described next on the basis of the attached figures forms the components of an apparatus for producing filter rods in a two-strand process.

  FIG. 1 is a perspective view, and FIG. 2 is a side view showing an apparatus for manufacturing a cigarette filter schematically by a two-strand method. In the illustrated embodiment, this device is composed of three components, each forming one device, and further comprises a device 2 for simultaneously producing two filter tow strands, and a filter tow strand produced from the device 2. A device 4 for carrying in activated carbon called charcoal and a device 6 for producing a filter rod from filter tow strands.

  As can be seen in FIGS. 1 and 2, in the illustrated embodiment, the device 2 for producing two filter tow strands consists of two sorting modules 12 present in the front and rear as viewed in the processing direction.

  Each sorting module 12 has a housing 14 whose upper surface is provided with an inlet 16 through which the filter tow band 8a or 8b enters. The filter tow strip 8a or 8b is pulled out of the filter tow valene not shown in the figure before entering the sorting module 12 and is present at the top of the sorting module 12 and the turning tow enlargement not shown in the figure is likewise It is arranged at the upper end of a support arm not shown in the figure and is directed towards the inlet 16.

  After entering through the inlet 16, the filter tow band 8a or 8b is guided through the sorting module 12 along a tow guide section not shown in detail. In order to decelerate the filter tow band downstream after the inlet 16, each sorting module 12 in the illustrated embodiment has a brake device 20 and contains a pair of brake rollers that are conventionally unrecognizable in the figure.

  After the brake device 20, the filter tow band 8 a or 8 b passes through different processing devices in each sorting module 12. After that, the filter tow band 8a or 8b is first subjected to the front stretching between the brake device 20 and the roller pair 22 located downstream, and the filter tow band 8a or 8b is guided by a stretching device known per se, The stretching device is formed by a roller pair 24 disposed downstream of the roller pair 22, and the main stretching is performed on the filter tow band 8a or 8b.

  Downstream of the lower roller pair 24, in the illustrated embodiment, the filter tow strip 8a or 8b passes through the processing device 26, and in this processing device, the filter tow strip 8a or 8b is washed with a liquid processing agent.

  After flowing out from the processing device 26, the filter tow band 8a or 8b is turned in each sorting module 12 in the direction toward the device 4 into which the activated carbon particles are carried. In the illustrated embodiment, both filter tow bands 8a, 8b are recognized in FIGS. 1 and 2 while a unique filter tow band 8a or 8b is formed and sorted in each sorting module 12. , And flows into the apparatus 4 for carrying the activated carbon particles in common. Therefore, the filter tow band is separated approximately in the vertical direction via the lower turning rolls 30a and 30b, and in this case, turned to the direction of the upper turning roll. In FIG. A first upper turning roll 32a for the tow band 8a can be recognized, and in an embodiment to be described later, a second upper turning roll located directly next to this upper turning roll indicated by reference numeral 32b is a second filter tow. It remains invisible in FIGS. 1 and 2 for band 8b. In addition, each upper turning roll performs a turning in a substantially horizontal direction with respect to the transport nozzle 34, the inflow finger 36 is connected to the transport nozzle, and the finger has a round shape of the filter tow band with respect to the filter tow strand. 1 further recognizes that the filter tow strips 8a, 8b have a flat strip shape first from the outflow from the sorting module 12 of the device 2 to the transport nozzle 34 at the outlet of the device 4. FIG.

  In the apparatus 4, the activated carbon particles are carried into the filter tow bands 8 a and 8 b between the upper turning roll and the transport nozzle 34. For this purpose, a supply device having a storage container 42 is provided according to FIGS. 1 and 2, the outlet not shown of which is connected to the distribution device 50 via a shaft 44 at the lower end. The storage container is filled with activated carbon particles, and the activated carbon particles reach the distribution device 50 through the supply shaft 44. The amount of activated carbon particles obtained via the supply shaft 44 is distributed by the distribution device 50 and brought to the filter tow bands 8a, 8b in a properly distributed shape. In the illustrated embodiment, the supply shaft 44 is connected to the lower end of the storage vessel, the distribution device 50 is seated under the supply shaft 44, and activated carbon particles are moved from the storage vessel 42 via the supply shaft 44 by gravity. To the distribution device 50. Furthermore, in the illustrated embodiment, the filter tow bands 8a, 8b are guided through the side of the distributor to the lower part of the distributor 50, so that activated carbon particles are sprinkled from the distributor 50 onto the filter tow bands 8a, 8b. From the distribution device 50, the distribution of the distributed amount of the activated carbon particles from the distribution device 50 to the filter tow strips 8a, 8b is likewise performed by gravity.

  An inflow finger 36 connected to the rear of the transport nozzle 34 forms a transition from the device 4 to the device 6 and forms a filter tow strand from the filter tow bands 8a, 8b. To finish filter rod.

  1 and 2, the supply device 40 has a single container reservoir 42 and a single supply shaft 44, whereas FIG. 3 shows a portion of the device 4 according to the first preferred embodiment of the invention. The supply device 40 is divided into two supply sections 40a, 40b. Further, in FIG. 3, the first filter tow band 8a and the second filter tow band 8b are shown in a cross-sectional view in an array. The first filter toe band 8a is guided along the first filter tow guide section, and the second filter tow band 8b is guided along the second filter tow guide section. Both filter toe guide sections are not shown in the figure. From the two supply sections 40a and 40b, the first supply section 40a of the first filter tow guide section guided to the first filter tow band 8a and the second of the second filter tow guide section guided to the second filter tow band 8b. Supply section 40b is incorporated.

  As can be further appreciated in FIG. 3, the first supply section 40a has a first storage container 42a and a first supply shaft 44a connected to the storage container and disposed at the bottom, and a second supply section 40b. Has a second storage container 42b and a second supply shaft 44b connected to the storage container and disposed in the lower part. Both storage containers 42a and 42b are used to receive activated carbon particles, and individual walls of the storage containers 42a and 42b or the storage containers 42a and 42b can be swung as a whole to avoid bridging the activated carbon particles. It can be formed or supported. In the first preferred embodiment according to FIG. 3, the dispensing device 50 comprises two coaxially positioned and rotatably supported dispensing rollers 52a, 52b, of which the first dispensing roller 52a is the first. Between the supply vertical shaft 44a and the first filter tow strip 8a, a second distribution roller 52b is disposed between the second supply vertical shaft 44b and the second filter tow strip 8b. The common rotation axis 53 of both distribution rollers 52a and 52b extends approximately in parallel to a plane in which both filter tow bands 8a and 8b travel below the distribution rollers 52a and 52b. Supply shafts 44a, 44b are placed on top of the distribution rollers 52a, 52b and exit directly at the top of the distribution rollers 52a, 52b by their outlets, as can be seen in FIG. On the other hand, both filter toe bands 8a and 8b run in the direction perpendicular to the rotation axis 53 and the image observation plane in FIG. 3 below the distribution rollers 52a and 52b, and the filter tow bands 8a and 8b and the distribution rollers 52a and 52b. The distance to the periphery of the is relatively small.

  In the embodiment shown in the figure, the groove-shaped depressions are formed by being distributed over the periphery, so that the distribution rollers 52a, 52b are formed as so-called groove rollers, and these groove-shaped depressions are parallel to the rotation axis 53. It extends and is lined up in the peripheral direction. FIG. 3 schematically shows, for example, some of these groove-like recesses 54.

  In the illustrated embodiment, the two activated storage vessels 42a and 42b arranged in parallel with each other cause the activated carbon particles to reach the supply shafts 44a and 44b located in the storage vessel by gravity. Both storage containers 42a and 42b can normally be filled with different activated carbon particles as required. Due to the opening at the lower end of the supply shaft 44a, 44b, the activated carbon particles fall onto the periphery of the distribution rollers 52a, 52b, thereby filling the groove-like depressions 54. The distribution rollers 52a and 52b convey the activated carbon particles in a certain amount by rotation to the filter tow bands 8a and 8b, where the activated carbon particles fall from the groove-like depressions 54 and thereby sprinkle onto the filter tow bands 8a and 8b.

  Since both the distribution rollers 52a and 52b in the illustrated embodiment are arranged in a narrow line, it is advantageous to arrange the separation thin plate 56 between the both distribution rollers 52a and 52b. The distribution rollers 52a and 52b are three-dimensionally separated from each other. In this manner, the activated carbon particles are prevented from reaching from one distribution roller to the other distribution roller.

  Therefore, the embodiment according to FIG. 3 offers the possibility of separate activated carbon particle guides for both strands for a two strand maker.

  As shown in FIG. 4, in the embodiment according to FIG. 3, each distribution roller 52a or 52b is individually driven by one separate motor 58a or 58b. Therefore, the rotational speed for each distribution roller 52a, 52b can be individually controlled, whereby a different distribution and different loading of the respective filter tow strips 8a, 8b can be realized.

  In order to control the amount of activated carbon particles, a control device not shown in the figure is provided to control the drive means 58a and 58b. Of course, the use of such a controller that operates online, i.e., in the current process, minimizes weight fluctuations in the filter tow strand. This is because, in order to obtain a constant weight of the filter to be manufactured, the amount of activated carbon particles supplied varies without being too strong. In this case, the supplied amount of activated carbon particles is controlled by a sensor, in particular the sensor is activated optically or using at least one of infrared light or microwave, or measures the electrical conductivity of the additive. It is formed as follows. In the case of speed fluctuation, the drive motors 58a and 58b of the distribution rollers 52a and 52b are appropriately controlled by the control device, so that the conveyance amount is controlled by adjusting the rotation speed of the distribution rollers 52a and 52b.

  FIG. 5 differs from the embodiment according to FIG. 3 in that an additional closing mechanism 60 is provided so that activated carbon particles can be fed from the respective feed shaft 44a or 44b to the distribution rollers 52a and 52b as required. It is different that it can be blocked. Therefore, in this embodiment, the activated carbon particle supply can be separated by the filter tow strips 8a and 8b as required, and manufactured from these so-called white filter rods.

  In the embodiment according to FIGS. 3 and 4, each supply section has only one storage container with a supply shaft connected to the storage container, FIG. 6 shows a preferred third embodiment, the supply section 40a is In the present case, there are a plurality of storage containers 42aa, 42ab, 42ac that are positioned side by side, and supply shafts 44aa, 44ab, or 44ac are connected to the lower end. Supply shafts 44aa, 44ab, 44ac are shown on the common distribution roller 52a. Furthermore, a mixing chamber 62 exists between the distribution roller 52a and the attached filter tow section for guiding the filter tow band 8a. Consistent structural details are suggested in the description of FIG. Therefore, in the embodiment of FIG. 6, different types of activated carbon particles across multiple supply strands can be prepared before the common dispensing roller 52a. The activated carbon particles are mixed with each other in the mixing chamber 62 before being delivered to the filter tow band 8a. However, it can be considered to selectively abandon the mixing chamber 62 and instead control the activated carbon particles directly from the common distribution roller 52a to the filter tow band 8a. This embodiment allows for rapid type change or material mixing with appropriate switching.

  FIG. 7 is different from the embodiment of FIG. 6 in that, instead of the common distribution roller, another distribution roller 52a, 52ab and 52ac is provided, and each of the distribution rollers is provided with supply shafts 44aa, 44ab, 44ac, which on the other hand is provided with a return conduit 64 which leads from the filter tow guide section which guides the filter tow band 8a to one of the storage containers. . The return conduit 64 consists in particular of a hose or pipe and is operated pneumatically, in particular with a suction operation.

  In the embodiment according to FIG. 7 as well, various types of activated carbon particles can be provided across a plurality of, here three, supply strands. In this case, in this embodiment, an activated carbon particle mixture is produced which is variable by individual changes and adjustments in the conveying speed or rotational speed of the individual distribution rollers 52aa, 52ab and 52ac. A very large amount of surplus activated carbon particles transported by the return conduit 64 or withdrawn from the filter tow band 8a is returned to at least one of the storage containers. In this case, the storage container 42ac is returned to the right (FIG. 7 right), and this storage container is provided only for receiving the returned activated carbon particles.

  Instead of this, for good completeness, the embodiment shown in FIGS. 6 and 7 contains only the feed section and is thus provided only for one filter tow guide section, and therefore one It only concerns the strand.

  In the embodiment described on the basis of FIGS. 3 to 7, one individual distribution roller is incorporated in each filter toe guide section, but optionally one common distribution roller for a plurality of filter toe guide sections. And providing a common distribution roller for a plurality of filter tow bands. This is shown by way of example in FIG. 8 as a preferred fifth embodiment, in which one common distribution roller 52 is incorporated in the two filter tow strands 8a, 8b. Thereby, in this embodiment, the same amount of activated carbon particles is loaded by the two filter tow bands 8a, 8b. This embodiment contains one second distribution roller and one second drive means.

  FIG. 9 shows a preferred sixth embodiment, which differs from the second embodiment according to FIG. 5 in that a distribution slider 66 is provided at the outlet of each supply shaft 44a, 44b instead of a closing mechanism, The difference is that each possible position can be adopted between the open state and the single closed state, but rather between these end states. For this purpose, the distribution slider 66 is movably supported by the transport path and thereby the mass flow of activated carbon particles. In this case, this movement is straight or caused by turning. For the purpose, the movement of the distribution slider 66, which consists of plate-like elements, is effected by means of associated drive means not specifically shown in the figure, which drive means are controlled by the previously mentioned control device. By partially opening and closing the distribution slider 66, the penetration amount of the activated carbon particles is appropriately adjusted to the distribution rollers 52a and 52b by the supply shafts 44a and 44b. Thereby, in this embodiment the dispensing slider 66 forms an additional dispensing means for the dispensing device 50. However, in this embodiment, only the distribution can be performed by the distribution slider 66 while the rotational speeds of the two distribution rollers 52a and 52b are kept constant.

  FIG. 10 shows details of the device 4 in the area of turning rolls 32a, 32b according to one preferred seventh embodiment. A special case of this embodiment is that the filter tow strips 8a, 8b are oriented substantially horizontally from the vertical alignment via the two turning rolls 32a, 32b and overlap at the same time, particularly as recognized in FIG. 10a. It is to be turned to the array that is located. After this turning, the activated carbon particles are supplied downstream of the turning rolls 32a and 32b. In this case, the activated carbon particles are guided from the distribution rollers 52a, 52b to the filter tow strips 8a, 8b through the spreading shafts 68a, 68b, where the filter tow strips are sprinkled with activated carbon particles. Alternatively, both filter tow bands 8a, 8b can be guided along the filter toe guide section so that they run offset by a distance A with respect to the central axis. In this embodiment, the joining of the filter tow bands located side by side is expensive and is omitted.

  In general, each dispensing roller is approximately perpendicular to the longitudinal extension or direction of motion of the attached filter tow strip by its axis of rotation. This is illustrated in FIG. 11a as an example of the first distribution roller 52a attached to the filter tow strip 8a. As long as the dispensing roller is formed as a grooved roller, that is the case in the representation of FIG. 11 so that the activated carbon particles are received and transported by the grooved depressions and an unobtrusive amount of activated carbon particles delivered to the filter tow band. The filter tow band shows a band-like cross section 70 which is spaced from each other and extends approximately perpendicular to the direction of movement of the filter tow band 8a. By changing the angle between the rotation axis 53 of the distribution roller 52a and the movement direction of the filter tow band 8a, the swinging process of the individual depressions in the distribution roller 52a is shown vertically with respect to the strand direction. This produces a uniform distribution of activated carbon particles. This is achieved by tilting the distribution roller 52a and the filter tow strip 8a relative to each other, as shown in FIG. 11b according to the preferred eighth embodiment.

  FIG. 12 a is a front view for two strands in the same arrangement as FIG. 11 a for a single strand in plan view, with the distribution rollers 52 a, 52 b extending longitudinally of the filter tow bands 8 a, 8 b by their common axis of rotation 53. In addition to being perpendicular to the part, i.e. to the direction of movement, at the same time, both filter tow bands 8a, 8b are aligned parallel to a plane located in at least the lower region of the distribution rollers 52a, 52b.

  However, compared to the arrangement of FIG. 12a, it can be considered that the two filter tow strips 8a and 8b run side by side in the activated carbon particle supply region, and both filter tow strips 8a and 8b are activated carbon. The longitudinal axis of the filter tow belt is inclined so that the particles face each other on the side surfaces receiving the particles from the distribution rollers 52a and 52b. This arrangement is shown in FIG. 12b according to a preferred ninth embodiment. The inclined installation of the filter tow bands 8a, 8b reduces the spacing between the central axes as shown by a comparison between the spacing Ba in FIG. 12a and the spacing Bb in FIG. As a result, the merging of the filter tow bands 8a and 8b or the tow filter track generated from the filter tow band is relaxed to a desired value with a delay of the strand interval (for example, 38 mm). After the inclination of the filter tow bands 8a and 8b is set, the activated carbon particles are spread from the distribution rollers 52a and 52b to the filter tow bands 8a and 8b.

  The so-called swivel revolver embodiment provides an exchange of production between the so-called black filter strands and the so-called white strands without activated carbon, with the additives, so that it is possible to switch back and forth between these two production possibilities. .

  FIG. 13 shows a preferred tenth embodiment with this type of swivel revolver. In this case, in FIG. 13, the swivel revolver is shown in a simplified form as a plate-like swiveling member 74, which has two plate-like portions 74a, 74b positioned at right angles to each other, and in particular As can be seen in FIG. 13b, it has an L-shaped cross section. The first portion 74a is assembled with all necessary ingredients that supply at least one additive to the filter tow strand. This is because the supply vertical shaft 42a, the distribution roller 52a rotatably supported there, the distribution vertical shaft 68a disposed under the distribution roller 52a, and the filter tow belt 8a to be processed are dispersed downstream in the transport direction. It is the transport nozzle 34a located after the pit 68a. Therefore, the first portion 74a of the swivel member 74 is used as a support for the arrangement consisting of the supply shaft 42a, the spray shaft 68a and the transport nozzle 34a, particularly as recognized in FIGS. 13a and b. In this case, this arrangement is such that the activated carbon particles are applied to the supply shaft 42a, the distribution roller 52a and the distribution shaft 68a which are positioned substantially vertically in the vertical direction at the positions shown in FIGS. 13a and b. Therefore, the activated carbon particles can reach the spreading shaft 68a from the supply shaft 42a via the distribution roller 52a by the gravity action, and can be dispersed on the filter tow belt guided through the spreading shaft 68a.

  On the other hand, only one other transport nozzle 134a is incorporated in the second portion 74b of the turning member 74. Therefore, the second portion 74b of the pivot member 74 is used as a substantially single support for another transport nozzle 134a, as recognized in FIGS. 13b and c.

  The turning member 74 is supported so as to be turned by 90 ° between the first turning state and the second turning state. The bearing receives a swivel joint 76 schematically illustrated in FIG. 13b. The swivel joint 76 is seated in the coupling region between the two mutually perpendicularly disposed portions 74a, 74b of the swivel member 74, with the swivel axis parallel to the transport direction of the filter tow strip 8a and hence parallel to the strand direction. It extends.

  FIGS. 13a and 13b show the swivel member 74 in the first swivel state in which the spreading shaft 68a and the transport nozzle 34a are located in the filter tow guide section where the filter tow band 8a is guided. Therefore, activated carbon particles are applied in this first swirl state. FIG. 13a can generally recognize the filter tow strip 8a, which is provided with activated carbon particles in the direction of the transport nozzle 34a after flowing out of the spreading shaft 68a, which is formed identifiable in black in FIG. 13a. Yes.

  By turning from the first turning state according to FIGS. 13a and 13b to the second turning state shown in FIG. 13c, the arrangement consisting of the spray shaft 68a and the transport nozzle 34a is turned outwardly from the filter tow guide section, instead. Then, another transport nozzle 134a is turned inward to the filter toe guide section. Thereby, in the second swirl state according to FIG. 13c, application with activated carbon particles is not possible, but rather, as further recognized in FIG. 13c, the filter tow band 8a is guided directly to the transport nozzle 134a without being affected. .

  Therefore, the pivot member 74 has two defined pivot states, a first pivot state according to FIGS. 13a and b and a second pivot state according to FIG. 13c. In this case, the arrangement is such that, in the first turning state, the spreading shaft 68a and the transport nozzle 34a located downstream and downstream are located in the (stationary) filter toe guide section, and in the second turning state according to FIG. It is carried out independently so that only another transport nozzle 134a is located in the filter toe guide section. In order to guarantee the fixing of the swivel member 74 in the first and second swivel states, a suitable fixing device is provided and has a preferred locking means for anchoring in the respective swivel state.

  All this makes it possible for the preferred tenth embodiment according to FIG. 13 to exchange between so-called black strands with activated carbon particles and so-called white strands without activated carbon particles. In this connection, for the sake of good completeness, the embodiment shown in FIG. 13 is provided only in the filter tow guide section and is therefore considered to correspond to only one strand.

  However, the exchange between the black and white strands can also be realized, for example, by a complete exchange of the device 4 illustrated in FIGS. For this purpose, the device 4 is provided as a modular functional structure group between the devices 2 and 6 and can be easily replaced as is schematically recognized in FIG. 14 where the preferred eleventh embodiment is shown. While a common foundation cradle not shown in the drawings of all machines or devices remains maintained, the device 4 is opened by such a foundation cradle and replaced by a conveying device 77 shown schematically in FIG. 14b. Is done.

  FIG. 15 shows a preferred twelfth embodiment, which differs from the embodiment according to FIG. 9 in that the distribution rollers 52a, 52b and the two filter tow bands are substantially replaced by a distribution slider arranged at the outlet of the supply shaft. A distribution thin plate 78 is disposed between the filter toe guide sections for guiding 8a and 8b, and this distribution thin plate is activated carbon guided from the respective distribution rollers 52a and 52b to the filter tow band 8a or 8b attached thereto. It affects the effective width of the particle flow and thereby the amount of activated carbon particles 70 to be applied. In the embodiment shown in FIG. 15, two distribution lamellas 78 are arranged in the center between the two activated carbon particle streams and thereby between the two strands, in which case the left distribution lamella 78 is supplied to the left supply. To the left activated carbon particle stream coming from section 40a, the right distribution lamella 78 is moved to the right activated carbon particle stream coming from right supply section 40a. The movement of the two distribution plates 78 takes place independently of one another. For this purpose, drive means operating independently of one another are provided and controlled by the previously mentioned control device independently of one another. The driving means is not shown in FIG. The motion of both distribution lamellas 78 occurs across the direction of motion of the particle mass flow, as shown in FIG. 15 by the double arrows. For this purpose, the drive means should be provided as linear drive means. In this connection, it is possible to consider, for example, coupling both inclined and arranged distribution lamellas 78 to a common unit, which is subject to a suitable linear movement. However, alternatively or additionally, both distribution lamellas 78 can be pivotably mounted, for example for this purpose, commonly on a hinge, with the pivot axis being substantially perpendicular to the viewing plane of FIG. For this purpose, the drive means should be provided as a swivel drive means. Thereby, in this embodiment the distribution sheet 78 acts as a guide sheet.

  Excess activated carbon particles received by the distribution lamina 78 are returned by a return conduit to a storage container of the auxiliary supply section 40a or 40b not shown in FIG. Regarding the structure and function of the return conduit 64, the specification suggests a fourth preferred embodiment shown in FIG. Unlike the embodiment of FIG. 7, the embodiment of FIG. 15 is provided with a return conduit 64 for each strand, and only the inflow end is recognized in cross section in FIG. And the inflow end has an upwardly open bowl shape for receiving the particles received by the respective distribution lamina 78.

FIG. 16 shows a preferred thirteenth embodiment in which a distribution device 50 has an adjustment mechanism 80 for selectively reducing the width of the filter tow band 8a in addition to the distribution roller 52a for one strand. The adjustment mechanism 80 according to FIG. 16 has two guide thin plates, the guide thin plates abut against the side edges of the filter tow band 8a, can move across the longitudinal extension, and are in an enlarged state. It is possible to move between the maximum interval C _max that matches the entire width of the band 8a and the minimum interval C _min that the effective width of the filter tow band 8a matches and decreases. For this adjusting mechanism 80, a driving means (not shown) is provided and is appropriately controlled by the previously mentioned control device. In this embodiment, in particular, the activated carbon particles are always sprinkled by the distribution roller 52a to the full width in the same amount. The full width corresponding to the maximum distance C _max means the maximum load of the filter tow band 8 a including the activated carbon particles 70. In contrast, the reduction of the effective width of the filter tow strip 8a to selectively minimum distance C _min, suitably slight activated carbon particles is impaired. Therefore, the amount of applied activated carbon particles is affected by the adjustment mechanism 80. In this case, surplus activated carbon particles are returned again in the process, for example a return device should be provided in line with the return conduit shown in FIGS.

  FIG. 17 shows a preferred fourteenth embodiment based on one strand, in which the distribution slider 66 is guided between the distribution roller 52a and the associated filter tow guide section thereby. It is arranged in the filter tow band 8a, has a hook shape that opens upward with respect to the distribution roller 52a, and is connected to the return conduit 64. The distribution slider 66 can be moved by the double arrow X across the longitudinal extension of the filter tow strip 8a and the transport direction and therefore across the strand. The structure and function of the return conduit 64 will become apparent from the description of the embodiment shown in FIGS.

  In the embodiment of FIG. 17, the distribution roller 52a conveys a specific flow of activated carbon particles. The amount of the activated carbon particles 70 is controlled by changing the position of the distribution slider 66, and the activated carbon particles are sprinkled on the filter tow band 8a. The portion of the activated carbon particle quantity received by the distribution slider 66 can be returned by the return conduit 64 and thereby fed back into the process.

  FIG. 18 shows a preferred fifteenth embodiment, which differs from the preferred third embodiment according to FIG. 6 in that movable separating walls 82, 84 are substantially provided between the supply shafts 44aa, 44ab, 44ac. The difference is that the filter tow band 8a is supported so as to be movable across the longitudinal extension and the transport direction and hence across the strand. Appropriate drive means should be provided to move the separation walls 82, 84 and are controlled by a previously mentioned controller not shown in FIG. With this arrangement, different types and qualities of at least one additive are utilized, and the dispensing roller 52a is fed simultaneously. The width to be adjusted by the adjustable separating walls 82, 84 of the individual supply shafts 44aa, 44ab, 44ac depends on the determined mixing ratio. If the supply shaft is adjusted to be wider, the proportion of each additive supplied by the supply shaft becomes higher in the distribution roller 52a and subsequently in the filter tow band 8a.

  FIG. 19 shows a preferred sixteenth embodiment, which differs from the sixth preferred embodiment according to FIG. 9 in that there is no dispensing roller and the dispensing device 50 has substantially only a dispensing slider 66 attached to the supply section 40a. Is different. The arrangement and function of the dispensing slide will become apparent from the description of the sixth preferred embodiment shown in FIG. At the lower part of the distribution slider 66 seated at the outlet of the supply shaft 44a, there is a collision thin plate 86, which is connected to a rocking device 88 and in particular has a metering tank. The collision thin plate 86 is inclined obliquely downward and ends directly at the head of the swing groove 90, and as recognized in FIG. 19, the direction of the filter toe guide section in which the swing groove guides the filter tow band 8a. It is inclined obliquely downward. In this embodiment, the distribution of the activated carbon particles occurs substantially exclusively by the distribution slide 66. After the supply shaft 44a flows out, the activated carbon particles fall on the collision thin plate 86 below the distribution slider 66, and the swinging device 88 detects the exact weight of the activated carbon particles. After the transition from the collision thin plate 86 to the rocking groove 90, the activated carbon particles 70 in the rocking groove 90 are conveyed to the filter tow band 8a as compared with a substantially constant mass flow.

  FIG. 20 shows a preferred seventeenth embodiment, which differs from the preferred sixteenth embodiment according to FIG. 19 in that a distribution screw 92 is assembled in place of the impingement thin plate and the oscillating device, and the distribution screw substantially The difference is that a uniquely defined supply is guaranteed. Normally this embodiment functions in the same manner as the preferred sixteenth embodiment shown in FIG. Thus, in a preferred seventeenth embodiment, the activated carbon particles are delayed by a substantially constant mass flow by the oscillating groove 90 and brought to the filter tow band 8a.

  At this point, for good completeness, the embodiment shown in FIGS. 19 and 20 contains only the feed section 40a and is thus provided for the filter tow guide section and therefore only on the strands. Applicable.

  FIG. 21 shows another detail of the device 4 in the area of turning rolls 30a, 30b and 32a, 32b according to a preferred eighteenth embodiment. The particularity of this embodiment is that the filter tow strips 8a, 8b are oriented approximately horizontally, and at the same time a substantially vertically arranged arrangement is first approximately longitudinally via the two lower turning rolls 30a, 30b. Are aligned and aligned to diverge from each other at the same time. In order to achieve this diverging alignment, as can be seen in FIG. 21a, the two downward turning rolls 30a, 30b, which are positioned approximately horizontally back and forth, are inclined to each other. For this reason, the inclined states of the rotation axes of the lower turning rolls 30a and 30b are arranged in two rows in an arrangement in which the portions of the two filter tow bands 8a and 8b that are turned approximately in the vertical direction are arranged side by side. Ends in upper turning rolls 32a, 32b, in which the filter tow strips 8a, 8b are oriented in a horizontal orientation and further aligned in an array, and downstream from these of the distribution rollers 52a, 52b. Activated carbon particles can be sprinkled on the bottom. As can be seen in FIGS. 21a and 21c, the upper turning rolls 32a, 32b are appropriately inclined with respect to each other, and the lower turning rolls 30a, 30b and the upper turning rolls 32a, 32b are formed into the filter tow bands 8a, 8b depending on the inclined state. A substantially uniform tensile stress is exerted over the entire width. In addition, the inclined state of the upper turning rolls 32a, 32b is recognized in particular in FIG. 21c, and without the tensile stress on one side being generated, the upper turning rolls 32a, 32b after the filter toe bands 8a, 8b are turned. Will be joined again. This form simplifies the further merging of the filter tow guide sections and thereby the filter tow bands 8a, 8b guided therefrom.

  FIG. 22 shows the same region of FIG. 21 and device 4, according to a preferred nineteenth embodiment. This embodiment is different from the eighteenth preferred embodiment according to FIG. 21 in that the lower turning rolls 30a and 30b positioned in the front-rear direction in the horizontal direction are not inclined but rather are parallel to each other at the same time. Another difference with respect to the eighteenth preferred embodiment according to FIG. 21 is that before the filter tow strips 8a, 8b are turned around the upper turning rolls 32a, 32b approximately horizontally and at the same time are turned side by side. After turning, the filter tow bands 8a and 8b are substantially horizontally oriented by the lower turning rolls 30a and 30b, and are swung around the longitudinal axis of the filter tow bands 8a and 8b in the vertical direction from the vertically arranged arrangement. Or to be twisted. In particular, as can be seen in FIG. 22a, the twisting or turning angle is approximately 90 °. Therefore, the array of upper turning rolls 32a, 32b located side by side is aligned approximately across the lower turning rolls 30a, 30b. As in the case of the preferred eighteenth embodiment according to FIG. 21, in this embodiment, the upper turning rolls 32a, 32b are slightly tilted and the filter tow bands 8a, 8b are again turned on as shown in FIG. 22c. There is no unilateral tensile stress in an undesired manner. Rather, also in this embodiment, the inclined state of the upper turning rolls 32a, 32b is selected so that a substantially uniform tensile stress is obtained over the entire width of the filter tow bands 8a, 8b. Furthermore, another merging of the filter tow bands 8a and 8b is simplified by the inclined state of the upper turning rolls 32a and 32b. In particular, as schematically shown in FIG. 22b, after the filter tow band has been turned, the upper turning rolls 32a, 32b travel to the lower part of the distributor 50 by the side of this distributor, from which they are loaded with activated carbon particles, and subsequently respectively. In FIG. 22b, the inflow finger 36a for the filter tow band 8a is shown in a recognizable manner.

  By conveying process air in the circuit, the air consumption of the device can be minimized. For this purpose, FIG. 23 shows a preferred twentieth embodiment, in which process air is drawn into the outlet of the inflow finger 36a through the suction pipe 94 by the blower 96 and again guided to the transport nozzle 34a via another conduit 98. The filter tow band 8a flows into the transport nozzle. This device not only achieves a reduction in air consumption, but rather avoids contamination of the surrounding air.

  The previously mentioned examples have been described in relation to the supply of activated carbon particles to the filter tow zone. Fundamentally, however, it can be considered that the previously mentioned embodiments are generally used for the supply of various particulate or powder additives.
