Description

Device for wrapping groups of filter segments with a wrapping material for producing multi-segment filters from the tobacco processing industry and multi-segment filter manufacturing device

description

The invention relates to a device for wrapping groups of filter segments with a wrapping material for producing multisegment filters in the tobacco processing industry. The invention further relates to a Mul ti segmentfil terherstel leinrichtung.

Devices for wrapping groups of filter segments with a wrapping material for producing multi-segment filaments from the tobacco processing industry are known per se. Here, for example. thought of a filter rod machine by the applicant, which is called KDF. By means of this strand forming device, for example. from DE-OS 2452 749, which corresponds to GB 15 22 139, and which was registered by the legal predecessor of the applicant, groups of filter segments or groups of filter rods are formed in a cross process by means of a cross-forming group forming device and then passed to the strand forming device in such a way that the groups of filter rods can be sheathed axially axially with the sheathing material. The group-forming device is a device that is to be completely replaced when the filter segments or the order of the filter segments are changed.

This is associated with a large financial outlay and little variability in the multi-fil ter manufacture 1 ung.

A typical applicant's group forming device is called GC E. Both the KDF 2E and the GC E are known in specialist circles.

Multi-segment filters or multi-filters are filters that consist of different segments, such as different materials. These materials are, for example, Cel 1 ulose acetate, paper, fleece, granules, sintered elements, hollow cylinders or hollow chambers and capsules and the like. Such multi-segment filters, which also include the term “multiple filter” in the context of this invention, are encased after formation of groups of filter segments, for example in a strand process, with encasement material such as paper and then in two, four or six -fold long filter rods cut up for further processing. With regard to the group forming device, reference is made in particular to the applicant's older application, the has the file number DE 101 46 917.9. This application is to be fully included in the disclosure content of the present application by reference.

From DE 27 27 663 C2 a device for supplying wrapping material for tobacco products is known, in which filter rod groups are combined with the aid of a roller drum and a roller plate to form multi-component filter rods by rolling connecting bands around adjoining end sections of each filter section of a group. Here, a single union band can span one or more filter sections and thus unite more than two sections of the filter rod. In general, however, the total width of the union bands is less than the length of the finished filter rod. This then results in gaps in the filter material in which no union bands have been wrapped around.

The Mul tisegmentfil ter produced in this way have the disadvantage that their diameter varies. Furthermore, the method for producing or uniting the groups of filter segments is disadvantageous because at least one fixed rolling surface is provided, which exerts a considerable force on this group at the moment of entry of the group to be rolled, without receding. Due to the rigidity of the rolling surfaces, the groups to be rolled can be damaged.

In contrast, the present invention has for its object on the one hand to provide a device for wrapping groups of filter segments with a wrapping material for the production of multi-segment filters of the tobacco processing industry, by means of which a diameter of the most uniform multi-segment filter ter produced can, and with which a gentle wrapping of the groups of filter segments is made possible, the wrapping process should be as reliable and simple as possible. Furthermore, it is an object of the present invention to provide a multi-segment filter manufacturing device which, on the one hand, solves the aforementioned task for the area of the device for enveloping groups of filter segments with a wrapping material, and on the other hand, a device for assembling groups of filter segments for the production of Multisegmentfiltem is further developed in such a way that variability in multi-ti ter production is possible. The corresponding device should also be inexpensive, in particular with regard to the variability in the production of different multifilters. Furthermore, it should be provided that both the device for enveloping groups of filter segments and in particular thus also the Mul isegmentfilterherstel 1 device should be designed to save space, in particular the corresponding operations that can be carried out with the corresponding devices or devices should be able to be realized on a shortened conveying path ,

This object is achieved on the one hand by a device for covering groups of filter segments with a covering material for the production of multi-segment filters of the tobacco processing industry, with a roller channel for rolling the groups with the covering material, the roller channel from adjacent strands of at least a first and at least one a second roller conveyor is formed.

This solution to the task has for the first time succeeded in wrapping groups of filter segments in a transverse axial process by means of rolling to enable appropriate conveyor belts. The device according to the invention has the advantage that a particularly gentle and space-saving wrapping of groups of filter segments for the production of multi-segment filters is made possible. In this case, by providing usually elastic bands, it is possible to provide a gentle covering, in particular slight differences in diameter of the filter segments being compensated for. In order to provide a particularly effective compensation of the diameter differences, a pair of conveyor belts is provided for each segment. Due to the fact that only groups of filter segments are enveloped, it is possible to provide a relatively ^" narrow roller belt, so that in a preferred embodiment of the invention a single first roller belt and a single second roller belt are provided. This considerably simplifies the device according to the invention in particular with regard to the control of the device.

In the context of this invention, the device according to the invention can also be called filter segment group wrapping device.

If, furthermore, a feed device is provided for feeding the groups to the roll channel, the feed device being designed as a feed drum which delivers the groups directly to the roll channel, a particularly smooth and exact transfer of the groups to be wrapped to the roll channel is possible.

The particular advantages of such a configuration and also further configurations of the devices according to the invention, which are described in the following, are referred to in particular Patent application EP 1 013 183 A2 referred to the applicant, which is to be incorporated by reference into the disclosure content of the present application.

A particularly preferred embodiment of the invention is present when the feed drum has a first deflection for one of the conveyor belts. In this embodiment, in which, for example, the deflection can be a groove formed in the feed drum in which the Ro'llband to be deflected runs, the rotary movement of the feed drum can simultaneously be used to drive one of the conveyor belts. This makes a particularly strong simplification of the device possible, since the double function of the feed drum means that an additional deflection roller or deflection disc can be saved for one of the conveyor belts. The feed drum is preferably rotatably mounted with the first deflection about a common axis. The feed drum is preferably firmly connected to the first deflection, the feed drum serving as a drive for the roller conveyor rotating on the first deflection by means of the first deflection.

If a removal device is provided for removing the enveloped groups from the rolling channel, the removal device being designed as a removal drum, a particularly space-saving device is provided.

The removal drum is also preferably assigned a second deflection for one of the conveyor belts, in particular the removal drum and the second deflection being rotatably mounted about a common axis. The discharge drum and the second deflection are preferably relative to one another about the common axis rotatable. In this way, the peripheral speed of the conveyor drum can work independently of the speed of the conveyor belt at a speed of the conveyor belt rotating on the conveyor belt. When the wrapped groups are removed, this enables removal from the rolling channel at the transport speed of the groups in the rolling channel, or at a higher or lower speed than the transport speed of the objects in the rolling channel. The device according to the invention can therefore be adapted very flexibly to different requirement profiles by the preferably possible relative movement between the second deflection and the discharge drum.

The removal device preferably takes over the enveloped groups essentially directly from the rolling channel, which enables gentle and quick as well as safe transfer.

In the device according to the invention, a feed drum which has receptacles for the groups to be rolled is particularly preferred. It is again preferred if the feed drum has receptacles designed as first webs, channels opening into the webs, which can be connected to a vacuum source for holding the objects. In one embodiment of the invention, the first webs are arranged transversely to the conveying direction of the feed drum. With the aid of such feed drums, the invention can be implemented particularly simply and reliably. In this embodiment, the objects to be wrapped are gripped by the feed drum or the webs on the feed drum at the moment when the conveyor belt revolving on the feed drum when the corresponding web is located in the circumferential point of the feed drum closest to the other roller conveyor. It is preferred if the roller conveyor rotating on the feed drum runs faster than the opposite roller conveyor. This ensures that at the moment of transfer of the groups to be wrapped to the roll channel, the groups roll forward. This is particularly preferred when the feed drum already transfers the objects to the rolling channel with the wrapping material attached. In this way, the rolling and thus the ^" wrapping of the objects can begin immediately at the beginning, ie directly when the groups are handed over, for example with attached wrapping material. It is therefore a defined and exact starting position of the Rolling set.

The exact transfer of the enveloped groups from the rolling channel to the discharge drum can in turn be improved with the aid of the webs mentioned above, which run transverse to the conveying direction of the groups in the rolling channel. On the one hand can be accelerated against a web at a higher speed than the circumferential speed of the discharge drum of the surrounding conveyor belt of the enveloped groups, so that they can then be held exactly and defined on the webs by means of the channels opening into the webs and the connected vacuum source. However, it is also possible that the enveloped groups are again accelerated by the discharge drum or the corresponding web when leaving the roll channel in the case of a discharge drum running at a higher peripheral speed than the roller belt rotating around the discharge drum. A further advantageous embodiment of the invention has a feed drum with second channels, which in turn can be connected to a vacuum source for holding wrapping material or wrapping material sections on the feed drum. For this purpose, second webs are preferably provided, which run transversely axially and which open into the second channels. With the help of such webs, the wrapping material sections can also be held in a defined manner on the feed drum.

Another preferred embodiment is characterized in that at least one of the roller belts is heated at least in the region of the roller channel. In such an embodiment, therefore, the adhesive connection which holds the wrapping material to the group to be wrapped when wrapped can be improved by the supply of heat.

If the revolving roller conveyor on the first deflection, assigned to the feed drum, consists of a plurality of sub-belts arranged at a mutual distance from one another, the arrangement of the webs can be used as a receptacle for the objects to be transported or the channels connected to a vacuum wave can be arranged on the webs Easier to implement by providing webs or roller conveyors alternately along the transverse axis to the conveying direction of the feed drum. On the other hand, if the conveyor belts are not divided, i.e. only a single first conveyor belt and a single second conveyor belt are provided, the groups can be wrapped more precisely, the channels connected to a vacuum source being able to come into operative connection with passage openings provided in at least one conveyor belt , around to hold the corresponding filter segments in the groups of filter segments or the enveloped groups in a suitable manner by means of a pressure force or suction air in order to be able to feed them exactly to the rolling channel or to be able to remove them exactly from the rolling channel.

The task is further enhanced by a multi segment filter! device with a device according to the invention for enveloping groups of filter segments with a wrapping material or a wrapping material section as described above, and a transfer device for transferring groups of filter segments - from ^{"• • '} '"^"of a filter segment group assembly device. Such a multi ti The filter filter group assembly 1 can be subdivided into a plurality of independent functional units.

Due to the fact that the filter segment group assembly device can be subdivided into a plurality of independent functional units, the greatest possible variability in the multi-unit manufacture! given, with the desire to produce different multi-filters, a quick and inexpensive adaptation is possible, in which the independent functional units may only have to be rearranged and adapted or, for example, only a few modules or functional units need to be purchased. In the context of this application, the term “functional units” also includes the term “module”.

If a functional unit is provided for each type of filter segment of a multi-segment filter, one is Particularly space-saving facility can be implemented. If one, in particular single, functional unit is provided for each filter segment of a multi-segment filter, a particularly high variability of the device is possible. A particularly simple combination of groups of filter segments is possible if the plurality of independent functional units are arranged in a row in such a way that at least some of the conveying elements of two adjacent functional units come into operative connection with one another, in particular are interlockable. Filter segments can then be put together in a particularly simple manner on these conveying elements. Preferably, the conveying elements comprise assembly drums and / or transfer drums. If the interlocking conveyor elements are arranged horizontally in a row, a preferred and simple embodiment of the device is given. Each functional unit preferably comprises at least one assembly 1 drum. The group of filter segments can preferably be conveyed transversely axially by means of the conveying elements, so that the device and also the independent functional units can have a correspondingly compact construction.

The multi ti seg entfil terherstel preferably comprises! device at least one conveyor belt, transverse to the conveying direction comprises receiving troughs for filter segments, at least two adjacent functional units each comprising at least one conveyor element which can be brought into operative connection with the at least one conveyor belt.

This preferred embodiment of the invention enables a particularly low-noise device because a large number of assemblies and drums Transfer drums that generate noise due to a large number of suction and compressed air circuits are eliminated. Furthermore, the continuous movement of a conveyor belt or a plurality of conveyor belts lying next to one another and moving in the same direction enables the filter elements or filter segments to be transported very gently, so that no further precautions are necessary in order to also transport very sensitive filter segments. Finally, it is advantageous that the operating personnel can keep a constant eye on the filter segments arranged on the conveyor belt or the conveyor belts, so that action can be taken in the event of an error. -

Each functional unit preferably comprises at least one conveyor element which can be brought into operative connection with the at least one conveyor belt. In this embodiment of the invention

Multi-segment filter manufacture! device extends the conveyor belt or the conveyor belts over all functional units, so that all assembly and transfer drums used in the other exemplary embodiments for the horizontal transport of the filter segments or groups of filter segments to the device for enveloping the groups of filter segments for the production of Multi-segment filters are provided, can be replaced.

The conveying direction is preferably horizontal. If means are provided for fixing filter segments in receiving troughs which are arranged on the conveyor belt or the conveyor belts, the filter segments can be transported very securely. With regard to the further configuration of the multi-segment filter production device and in particular also the conveyor belt or conveyors, reference is made in full to a German patent application filed by the applicant on the same day as the present application with the title "Device for assembling groups of filter segments for Manufacture of multi-segment filters for the tobacco processing industry and hollow drum ".

An inventive

Multi-segment filter manufacturing device with an inventive device for assembling groups of filter segments for the production of multi-segment filters is shown in Fig. 1. This is a group forming device 41, although independent functional units 60.1-60.3 and 61.1 are used in each case. The functional units 60.2 and 60.3 are soft element units by means of which two individual filter segments are fed (FIG. 5a), the functional unit 60.1 is a soft element unit by means of which a single filter plug or a single filter segment of twice the working length is fed , and in the functional unit 61.1 by a hard element unit. Storage tanks 53.1 - 53.3 and 54.1 are provided in each of the functional units, with a soft storage tank 53.1 - 53.3 being naturally provided in We-iehel ementei 60.1 - 60.3 and a hard element storage tank 54.1 in hard element unit 61.1. In the soft element units, soft segments or soft elements, for example made of Cel 1 ulose acetate or a fleece, are processed and the processed segments are placed on a drum, whereas in the hard element unit hard segments, such as sintered granules, sleeves filled with granules or empty sleeves, be positioned on drums. The group forming device 41 or the independent functional units are supplied with energy by means of an energy supply unit 58.

By means of the multi-segment filter manufacturing device acc. Fig. 1 are, for example, Mul tisegmentfil ter for cigarettes that have four filter elements.

There is now, for example, a soft element of double useful length in the middle of the corresponding trough 84 of the assembly 1 drum 64.2 (see FIG. 6 a)). Hard elements can then be arranged adjacent to this soft element of twice the useful length, whereupon, by means of the functional unit 60.2, two soft elements are arranged outside around the arranged hard elements. Finally, by means of the functional unit 60.3 arranged closest to the transfer unit 62.1, two further soft elements are arranged to the left and right of the group of filter elements in the respective troughs of the transfer drum 63.6 or assembly drum 64.2, aligned transversely axially. The group of filter segments formed in this way is then transferred to a transfer unit 62.1 and, by means of the transfer drums 63.1-63.3 known per se, transversely axially onto a supply drum 2 of the device for enveloping groups 4 of filter segments 5.-1 -5.7, 83, 87 for production of multi-segment filters 49 of the tobacco-processing industry, which is also referred to below as a wrapping device, in order to then use wrapping paper which is pulled off a bobbin 19 to form it into a multi-segment filter 49. Standard filter wrapping paper can be used.

Multiple filters can be produced, which are processed as 2, 4 or 6 filter rods in the applicant's MAX filter attachment machine using tobacco sticks to filter cigarettes.

The wrapping device according to the invention, which is also shown schematically in FIGS. 1 and 2, is discussed in more detail in the context of the figure description of FIGS. 3 and 4.

2 shows a schematic side view of a further exemplary embodiment of the multi-segment filter device 11 according to the invention. Instead of the transfer drums 63.5 used in FIG. 1 - 63.7 and the compilation used there 1 drum 64.1. - 64.3, a conveyor belt 120 is used, which can hold and transport filter segments over all functional units 53.4 - 53.6 and 54.2. For this purpose, receptacles are preferably provided in the conveyor belt 120, which are not shown in this figure. These recordings include suction air openings, which can be operatively connected to a vacuum box 123. The conveyor belt 120 is driven in the conveying direction 130 by a drive wheel 121 and is deflected around a deflection wheel 122. A cleaning box 124 is also provided, by means of which the conveyor belt can be cleaned accordingly. A detailed description of the conveyor belt 120 can be found in the applicant's German patent application, filed above on the same day, entitled "Compilation device of groups of filter segments for the production of multi-segment filters of the tobacco processing industry and hollow drum ". In this regard, reference is made to the description of this in the patent application just mentioned.

The filter segments deposited on the conveyor belt 120 are brought together in groups by the corresponding depositing and then fed via ^" the transfer drums 63.9 and 63.10 (the transfer unit 62.2) to the supply drum 2 of the wrapping device according to the invention.

The wrapping device according to the invention is shown in FIG. 3 in a schematic side view. The filter segment groups 4 are transferred from a transfer drum 63.1 in the conveying direction or direction of rotation 14.1 to the supply drum 2, which moves in the direction of rotation 14.2. In an area of engagement one Knife drum 7 with a paper transport drum 3, on the wrapping paper 9, which has been drawn off from a reel 19, the wrapping paper is divided into wrapping paper sections by means of the knife drum 7. The wrapping paper sections are then attached to the filter segment group 4. For this purpose, glue 33 from a glue container 12 is applied beforehand to the wrapping material 9 by means of a glue roller 11, which is in operative connection with a glue disc 10. The paper transport drum 3 moves correspondingly somewhat faster than the wrapping paper 9 is supplied so that the wrapping ungspapierabteile rest on the paper transport drum 3 at a distance after cutting by the knife drum 7.

The wrapping material section 6, which is attached or glued to the respective filter segment group 4, is brought into the effective area of a feed drum 23 which rotates in the direction of rotation 14.3. Arrived there, the filter segment groups 4 are preferably held in receptacles on corresponding webs 36 by suction air and preferably also the UmhuUungsmaterial sections 6 are held accordingly by suction air. The groups of filter segment groups 4 and wrapping material sections 6 are fed by the feed drum 23 directly into a rolling channel 25, which is defined by at least one first rolling belt 18 and at least one second rolling belt 20. The at least first roller conveyor 18 can be a plurality of sub-conveyor belts or a single roller conveyor. Likewise, the at least second roller conveyor can be a plurality of sub-conveyor belts as well as a single roller conveyor. In the variant with a large number of sub-bands, these are designed such that they move essentially parallel to one another. The first roller conveyor 18 preferably moves faster than the second roller conveyor 20, so that a corresponding rewinding of the filter segment groups 4 with the sheathing sections 6 is carried out. The second roller belt 20 is deflected around a roller 21 and a roller 22 in the respective direction of rotation 14.5 and 14.6. The umrollten filter segment groups 4 that are formed so as to Multiseg- ment filter 49 are transferred at the end of the rolling channel 25 to a conveyor drum 24, the respective receiving troughs 28 and ridges 37 ^■ - comprising; Then the Mul tisegmentfil ter 49 are transported on a transport drum 30 for further processing, for example. To put together with tobacco sticks and to provide a covering paper section.

The feed drum 23 has webs 36 arranged at a uniform distance on its circumference. The webs 36 are arranged on the circumference at regular intervals. The webs 36 run parallel to the axis of rotation of the feed drum 23. First vacuum channels 32 (see FIG. 4) are provided on the webs and are connected to a vacuum shaft 40. The filter segments can be held on the webs 36 with the aid of the vacuum channels 32. In order to hold the wrapping material sections 6 on the feed drum 23, further vacuum channels are provided in the feed drum 23, which hold the wrapping material 6 sections 6. However, these further vacuum channels are not shown in the figures. At the point which is defined on the circumference of the feed drum 23 by the section AA, the side of the filter segment group 4 facing the feed drum 23 comes into contact with one also on the feed drum 23 rotating first roller conveyor 18 in contact. The filter segment group also comes into contact with a second roller conveyor 20 at this point. The roller channel 25 thus begins at this point. The first roller belt 18 runs at the circumferential speed of the feed drum 23. The second roller belt 20 runs at a speed which is lower than the speed of the first roller belt 18.

The number of rewindings of the filter segment group 4 in the roller channel 25 depends on the difference in the speeds of the roller belts 18 and 20. By changing the speed of the roller conveyor 18, the number of rewindings of the filter segment group 4 in the roller channel 25 can be changed. The conveying directions of the first roller conveyor 18 and the second roller conveyor 20 are the same in the region of the roller channel 25.

The discharge drum 24 also has webs 37 arranged on the catch side. The discharge drum 24 runs at a circumferential speed and is rectified with the feed drum 23. The speed of the discharge drum 24 is lower than the conveying speed of the first roller belt 18. Thus, the covered filter segment groups 4 or multi-segment filters 49 leaving the roller channel 25 become the first roller belt 18 pressed against the webs 37 serving as receptacles in the discharge drum 24. There is therefore a precise and reliable transfer of the multi-segment filter 49 from the roller channel 25 with the aid of the first roller belt 18 to the webs 37 acting as receptacles on the discharge drum 24. On the webs 37 vacuum channels for holding the Mul tisegmentfilter 49 are also provided on the discharge drum 24.

FIG. 4 shows a schematic sectional illustration along the section A-A from FIG. 3. At this point there is a group of filter segments 5.1-5.7 in the rolling channel 25 starting there. The filter segments 5.1 - 5.7 are shown hatched accordingly. These filter segments 5.1-5.7 are clamped between the first roller belt 18 and the second roller belt 20. In this exemplary embodiment, the first roller belt 18 is divided into 8 partial belts. However, an embodiment can preferably be provided in which a single roller belt 18 is provided, the vacuum channels 32 shown in FIG. 4 being able to connect to openings in the roller belt 18 so that a vacuum acts on the filter segments 5.1-5.7 can. In Fig. 4, a respective web 36 is also shown in some broken representations. Furthermore, a vacuum source 40 is shown in FIG. 4, which can be brought into operative connection with the vacuum channels 32.

5a) schematically shows a soft element unit 60.2, 60.3 according to the invention, with which two individual filter segments are fed. In a soft element reservoir 53.1, soft filter rods 80, such as, for example, Cel 1 ulose acetate, are introduced via a feed element 70.1. The corresponding filter rods or filter elements 80, for example, 8 times the length of use, are removed by means of a removal drum 8.1. The deflector roller 71.1 is provided for a secure removal of the filter elements 80. A device for removing rod-shaped articles a stock is known, for example, from DE 25 05 998 C2, which corresponds to US 4,020,973.

The filter elements 80 are then cut on the removal drum 8.1 by means of a first circular knife 72.1, which is operated in a rotating manner and is constantly ground on a grinding element 73.1, into two filter elements 81 four times the length of use. Thereupon two further cuts are made by two further circular knives 72.2 which are arranged one behind the other, of which only the front circular knife can be seen in FIG. 5a), so that the filter elements 81 are used in a total of four filter elements 82 twice! be cut.

There is then a transfer of the four filter elements 82, which are arranged longitudinally axially on the removal drum 8.1, as shown, for example, in FIG. 5b), to a relay drum 13.1, by means of which the filter elements 82 are staggered, as in FIG. 5b ) is also indicated. The next step is a transfer to a sliding / cutting drum 74.1, in which a transverse axial alignment of the filter elements 82 is first carried out, in order then to cut them into two filter plugs 83 with the circular knife 72.3. The filter plugs 83 cut in this way are transferred to a transfer drum 63.4 in order to then be transferred to a pushing / transfer drum 75.1 in which the filter plugs 83 are pushed apart. Finally, the filter plugs 83 pushed apart are transferred to a compilation drum 64.1 and then to a transfer drum 63.5, which can be brought into operative connection with a compilation drum 64.2-64.5 of a further functional unit, in order to filter elements deposited on the transfer drum 63.5 with those on the to further assemble 1 drum 64.2 - 64.5 put together filer elements.

6a) shows a further exemplary embodiment of a functional unit 60.1 according to the invention in a schematic illustration. With this functional unit 60.1, a single filter plug with a double working length is fed. The difference to the functional unit 60.2 or 60.3 from Fig. 5a) is that instead of the downstream first transfer drum 63.4, a relay drum 13.3 is provided, by means of which the cut filter plugs 83 are staggered and transferred to the push / transfer drum 75.2 * so that A maximum of only one filter plug 83 is arranged per trough in the sliding / transfer drum 75.2 or per trough in the assembly drum 64.2 and transfer drum 63.6 assigned to this unit. In Fig. 6b) and Fig. 5b) is also schematically shown the receiving trough 84 of the assembly drum 64.1 and 64.2. With the functional unit according to FIG. 6 a), the first and possibly the last filter segment of a multi-segment filter are preferably inserted.

7a) is a hard element unit according to the invention

61.1 - 61.3. From a hardship! ement storage containers 54.1 are fed via two feed shafts 86.1 and

86.2 hard filter elements 87 fed to two extraction drums 8.3 and 8.4. For this purpose, as schematically indicated in FIG. 7 a), the feed chutes 86.1 and 86.2 can be moved so that the hard filter elements 87 can be transferred as gently as possible into the removal drums 8.3 and 8.4. The removal drums 8.3 and 8.4 can also be designed accordingly in order to enable a rapid transfer of many elements. For this, in particular, the patent application referred to the applicant with the title "transfer device and bowl drum and method for transferring cigarette components", which has the official file number DE 101 46 992.6. The content of the applicant's aforementioned patent application should be included in full in this patent application.

The staggered hard filter elements 87, as indicated in FIG. 7b), are then transferred in sliding drums 16.1 and 16.2, in which the hard filter elements 87 are arranged transversely axially in the successive receiving troughs. The cross-axially aligned hard filter elements are transferred via a transfer drum 63.8 to the assembly drum 64.3 of this unit and then transferred to the transfer drum 63.7.

The soft element units 60.4-60.6 of FIG. 2 essentially correspond to the soft element units 60.1-60.3 of FIG. 1. Likewise, the hard element unit 61.2 of FIG. 2 essentially corresponds to the hard element unit 61.1 of FIG. 1. The same applies to the transfer unit 62.2 of FIG. 2 and the transfer unit 62.1 of FIG. 1. In this case, only in comparison to FIG. 1 in FIG. 2, a conveyor belt 120 is provided which replaces the transfer drums 63.5-63.6 and 63.3 and the feed drum n 64.1-64.3. This makes it possible to implement a quieter machine that can transfer and transport the filter elements more gently.

The use of independent functional units in a device for compiling groups of filter segments for the production of multi-segment filters makes it possible, for example when using hard elements, by using several modules To achieve an increase in production output. A high production output is also possible if only soft modules or soft element units are used. In particular, two to five filter segments can be produced per multi-segment filter. Appropriate granules are preferably used in hard elements.
