The invention relates to a Filtersegmentzusammenstellvorrichtung the tobacco processing industry with a filter Segmentlauf for queraxia len transfer of a filter segment on a Filtersegmentzusammenstell- organ.

The invention further relates to a method for assembling filter segments of the tobacco processing industry in a transverse process.

Such devices and methods are needed to produce beispielswei se cigarette filter single or multiple use length, which connected in cigarette manufacturing machines with tobacco sticks who the.

From EP 1 393 640 B 1 a corresponding method and a device for assembling groups of filter segments is known. The device shown there enables an extremely variable combination of filter segments to corresponding groups of filter segments. instruments. For this purpose, corresponding units which are provided as modules or cabinet elements are disclosed, which have a plurality of drum-shaped conveying and processing elements per unit, which are described in EP 1 393 640 B 1 as soft element unit 1 0-14.

Thus, for example, a filter run of a soft element unit 10, which is shown in FIG. 1 of EP 1 393 640 B1, has a removal drum 22.1 which is in engagement with two circular knives 27 to remove it from the magazine or the storage container 21 .1 Cut filter rods of multiple use length twice, then on the staggering drum

23.1 to stagger, then on the sliding / cutting drum 24.1 once again cut the corresponding already cut into three filter segments filter rods each in aligned positions and then cut again. These cut filter segments are then staggered in a staggering drum 25.1 and pushed through a sliding drum.

/ Transfer drum, which connects, passed on a compilation drum 28.1. Although this filter segment run or Filterstablauf already has relatively few conveying and processing organs, but could be further optimized.

EP 0 383 970 B 1 discloses an apparatus for producing filter cigarettes, wherein two filter runs are provided in FIG. 1, which deliver filter segments onto a large bowl drum 142. US 3,067,644 A discloses a device for conveying and cutting filter rods in filter rod segments.

WO 2008/081 340 A2 discloses a filter cutting system. It is the object of the present invention to provide a filter segment assembling device for the tobacco processing industry and a corresponding method for assembling filter segments of the tobacco processing industry, in particular groups of filter segments, which with less number of components provides an efficient and variable Production of assembled filter segments or groups of filter segments, allows.

This object is achieved by a filter segment assembling device of the tobacco processing industry with a filter segment run for transversely axial transfer of a filter segment to a Filtersegmentzu- assembly, wherein a removal device is provided in the filter segment run, which is adapted to remove a filter rod multiple use length from a filter magazine, wherein a sliding / cutting device is provided in the filter segment run, which is adapted to receive the filter rod multiple use length, wherein the sliding / cutting means comprises wells for receiving filter rods, which is further developed in that the number of wells is a prime, the greater than or equal to 29, in particular greater than or equal to 37, is.

By providing such a filter segment assembly device, a plurality of organs for conveying and processing filter rods or filter segments can be saved. In this case, provision is made in particular for the removal device and the sliding / cutting device to rotate around an axis of rotation during operation. In this way, a filter rod multiple use length, for example, on a sliding / cutting device, which is preferably designed as a sliding / cutting drum, are cut several times. With each revolution of the sliding / cutting device, a cut can thus be made through the filter rod or the filter segments. As a result, even a sliding / cutting drum or a cutting drum can be saved.

By making the number of troughs of the pushing / cutting drum a prime number greater than or equal to 29 or 37, on the one hand, a large number of filter rods can be introduced, so that high efficiency is enabled, and on the other hand it is ensured that a very high variability is possible. Hereinafter will be discussed in more detail later. The removal device may be formed as a removal drum and this example, have a removal ring body, which is provided with wells. Accordingly, the sliding / cutting device may be formed as a sliding / cutting drum, for example, a

Sliding ring body having corresponding wells. In the sliding / cutting device, not only filter rods can be displaced accordingly, but also filter segments can be displaced. Particularly preferred is a number of wells of the sliding / cutting drum of 61 wells.

Preferably, the sliding / cutting device has a stop, are slid or slidable on the recorded in the troughs filter rods or filter segments, in particular a

Cutting device is provided, which is designed to cut off at least one filter segment at an adjustable distance from the stop of the filter rods. Due to the adjustability of the distance, a very variable device and a very variable method are possible. For example, an 8-inch length filter rod, 8 cm long, could cut the filter rod all in all into 8 filter segments through a distance of 1 cm to the stop by 7 cuts of the cutter for a total of 7 passes of the slide / cutter. The first cut then a filter segment is cut into a length of 1 cm and a second filter segment of 7 cm remains, which is moved in the next U mlauf the sliding / cutting device to the stop to there in a further first filter segment with a length of 1 cm, leaving a second filter segment of 6 cm length. In this way, filter rods or filter segments of different lengths are then arranged in the adjacent depressions of the sliding / cutting drum, in particular in the manner of organ pipes.

Preferably, the sliding / cutting device is designed so that the filter segments, which are arranged between the stop and the cutting device, are dispensed or deliverable. Thus, a cut filter segment which has a length which corresponds to the distance of the cutting device to the stop, is always discharged from the sliding / cutting drum, whereas the other remaining second filter segments remain on the sliding / cutting device and continue along revolve around the drum. As a result, after a corresponding number of cuts, a second filter segment is pushed against the stop, which already has the corresponding length which has the spacing of the cutting device from the stop.

This filter segment is then no longer cut, but simply discharged, creating a free trough, which is then filled again with a filter rod multiple use length. This is done in the above example after 8 cycles of the sliding / cutting device.

By using a prime number of troughs, regardless of which trough number the tapping means or the accelerator device adjoining the tipper means, it never happens that a filter rod is to be introduced into a trough which is still occupied.

Preferably, the removal device has troughs for receiving filter rods, wherein the number of troughs can be variably predetermined and / or an accelerator device adjoins the removal device, which has troughs whose number can be variably predetermined.

In particular, a filter run is preferred, which has as active conveying elements for filter rods or filter segments only the removal device or removal drum, the sliding / cutting device, in particular sliding / cutting drum, and the Zusammenstellorgan or a compilation drum or a corresponding assembly conveyor with corresponding wells. In addition to this, it can also be provided that a sliding drum adjoins the sliding / cutting drum, which then transfers filter segments or groups of filter segments pushed into an end position onto a assembly element or a compilation drum, this assembly element then preferably being mounted on an axis of rotation rotated, which corresponds to the axis of rotation of the sliding / cutting drum or is arranged on the same shaft.

Preferably, the variability is given by a different number of active wells.

For this purpose, for example, the removal device or removal drum have a removal ring body, which is easily replaceable. Alternatively, variable suction air connections can be arranged on the troughs or troughs can be set blind by introducing bodies. Furthermore, alternatively, a click drum with a variable

Number of wells may be provided.

For the variant of the click drum, reference is made to EP 2 921 062 A1. There, a conveyor drum 2 is disclosed, with the trough elements. 6 can be provided. For this purpose, the depression elements 6 have bushes 14 on the underside thereof, which can be inserted into suction bores or suction openings of the conveying drum. It can then be used corresponding base body or well elements, which have a width which makes it possible that in each distributed over the circumference Saugluftöffnung a depression element is introduced or, for example, only every other or every third, etc., in which case the other Saugluftöffnungen through Closing means can be closed or to the well elements an area extended in the circumferential direction of the conveyor drum is provided, which closes or seals off the suction air openings spaced from the well in the conveyor drum. The conveyor drum disclosed in EP 2 921 062 A1 can be used as a removal device. It can also be used as a sliding / cutting device.

The maximum number provided here is preferably 120 and can be varied by the variability described above, and in particular be reduced or reduced accordingly. With a corresponding number of base troughs, ie. A maximum number of troughs, which is 240, 120 or 60, results in a reduced active trough number by dividing the base trough number by a natural number, the natural number being selected so that no residue is created during the division , Thus, for a basic well number of 120, n = 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 30, 40, or 60.

Particularly preferably, the removal device is designed as a removal drum, which has a removal ring body having a number of troughs corresponding to the base trough number. It is then possible simply by replacing the removal ring body to vary the number of troughs of the removal device or removal drum.

The term "removal ring body" may also be understood to mean a removal drum body. "Sliding ring body" may also be understood to mean a sliding / cutting drum body.

The fact that two removal ring bodies or two removal drums are provided means, in particular, that two consecutive two on the rotation axis or on a common shaft in Muldenlängsachserichtung

Removal ring body or two removal drums are arranged. Correspondingly, the provision of two shear-cut ring bodies on a rotation axis means, in particular, on a common shaft, in the longitudinal direction of the trough or in the direction of the rotation axis two Sliding ring body are arranged one behind the other.

In this case, the push-cut ring bodies may preferably be mirror-symmetrical to one another, for example two pairs of sliding-cut ring bodies may be mirror-symmetrical to one another in each case. These can each have a stop, which is arranged for example centrally between the Schiebeschneidringkorpern.

In the context of the invention, mirror-symmetrical means that the filter rods or filter segments are arranged on one side of the sliding / cutting device or of the respective sliding / cutting ring body which adjoins the other sliding / cutting ring body which is adjacent thereto , In particular, two sliding / cutting ring bodies arranged mirror-symmetrically with one another preferably share a common stop body, which is arranged along the circumference of the sliding / cutting body between the respective sliding / cutting ring bodies.

In addition, a sliding drum is preferably provided which pushes the filter segments accommodated by the slide-cut ring bodies to one side and delivers them to the assembly member.

Preferably, a cutting drum is provided between the sliding / cutting device and the assembly element, wherein in particular a spreading drum adjoins the cutting drum in the filter segment conveying direction. Although this measure increases the number of conveying and / or processing organs, it may also be advantageous in certain constellations, for example, if two identical filter segments are to be dispensed at a distance from one another on an assembly device, preferably a compilation drum or a collating conveyor belt. When spacing the filter segments, preference is given to a spacing in the longitudinal axis of the filter segments.

Preferably, a multi-segment filter manufacturing machine of the tobacco processing industry is provided with a filter segment assembly device according to the invention, wherein a transfer device is provided which dispenses the cross-axially assembled filter segments onto a strand forming device or wherein a device for wrapping the assembled filter segments with a wrapping material strip is provided in a rolling process ,

/ Cutting device is discharged.

In particular, by this measure, ie. in particular, the provision of a sliding / cutting device which, in several rounds, produces a film terstab multiple use length cuts into several filter segments, whereby always a filter segment is delivered, a very space-saving and resource-saving process is possible.

Preferably, recesses of the sliding / cutting device that are freed are again covered with filter rods. For this purpose, preferably only released troughs of the sliding / cutting device are again covered with filter rods.

Alternatively, it can also be provided to occupy the wells with filter rods in which only a first filter segment is arranged and then discharged after occupancy with the new filter rod, whereupon then the filter rod is pushed to a stop, then in a first filter segment and a second filter segment to be cut. This accelerates, in particular, the engagement process of the method and the filter segment assembly device.

Preferably, the slide / cutter has a number of wells for receiving filter rods and filter segments, which is a prime number that is 29 or 37 or greater.

Preferably, at least two filter runs are provided with parallel and at least partially collinearly aligned depressions on at least two removal annular bodies of a removal device and also with parallel and at least partially collinearly aligned depressions on at least two sliding cutting ring bodies of a sliding / cutting device. The method is preferably carried out in at least two filter runs then with these features.

Preferably, a sliding / cutting device with a number of wells which is a prime number greater than or equal to 29, in particular greater than or equal to 37, is used in a filter run of a filter segment assembling device of the tobacco processing industry. Particularly important preferred is a number of troughs of 61.

The drums provided with different troughs according to the invention or the corresponding removal body preferably have different pitches for increased variability. Particularly preferred is an increased variability by different division or number of wells of the removal ring body, whereby the variability can be increased by providing interchangeable removal ring bodies.

By providing a sliding / cutting device, preferably in the form of a sliding / cutting drum, preferably comprising two or more sliding cutting body with a number of wells which is a prime number and greater than or equal to 29, in particular greater than or equal to 37, preferably 61, is efficient processing of the filter rods into filter segments and efficient grouping of filter segments. In this case, preferably two, in particular preferably at least three, in particular four, filter runs are arranged on corresponding removal ring bodies or removal drums arranged on a rotation axis or a common shaft, as well as a corresponding sliding / cutting device with a corresponding number of slide-cut ring bodies or sliding elements. / Cutting drums, which are arranged on a common axis of rotation and in particular a common shaft possible. In this case, two or more filter runs, so to speak, are made possible in parallel on respective common axes of the conveying members or processing members. This makes a very efficient and space-saving filter segment combination possible. The rotational speed of the corresponding removal device and the sliding / cutting device and the Zusammenstellorgans are approximately equal to the peripheral speed. In the event that an accelerator device is provided between the removal device and the sliding / cutting device, the speed between the removal device and the sliding / cutting device adapted.

Further features of the invention will become apparent from the description of embodiments according to the invention together with the claims and the accompanying drawings. Embodiments of the invention may satisfy individual features or a combination of several features.

The invention will be described below without limiting the general inventive idea by means of embodiments with reference to the drawings, reference being expressly made to the drawings with respect to all in the text unspecified details of the invention. Show it :

7 is a schematic three-dimensional representation of the embodiment according to FIG. 6. In the drawings, the same or similar elements and / or parts are provided with the same reference numerals, so that apart from a new idea each. 1 shows a multisegment filter production device with a device according to the prior art for assembling groups of filter segments for the production of multi-segment filters in a schematic side view. The multi-segment filter manufacturing device is divided into corresponding units. The device is subdividable according to the patent application DE 101 55 292.0 of the Applicant in a plurality of independent functional units. The functional units are in this embodiment, some soft element units 1 0-14, two Ü transfer units 15 and 1 6, which can also be represented as a transfer unit, and a corresponding strand forming unit 17, which is shown only very schematically.

The soft element units 1 0-14 are similar to each other. These essentially correspond to the soft element units of FIG. 5a) of DE 1 01 55 292.0 of the Applicant. With regard to all the details of these soft element units, reference is explicitly made to the patent application DE 101 55 292.0. The soft element units 1 1, 12 and

13 differ from the soft element units 10 and 14 in that a further circular knife 27 is provided by means of which the supplied filter elements are cut once more. In this embodiment, five soft element units 1 0-

14 has been used. Instead of or in addition to these soft element units, it is also possible to use hard element units which, instead of a filter element made of cellulose acetate or nonwoven, for example, have a hard filter element such as sintered elements, hollow cylinders or hollow chambers and capsules

Granules can be filled have. In the case of a corresponding hard element unit, for example, one has to think of the one described with reference to FIG. 6a) of DE 101 55 292.0. The soft element units 1 0-14 of Fig. 1 comprise corresponding reservoir 21 .1 -21 .5, which may for example have filter elements 12 times the use length or, for example, such 16 times the use length. In the soft element unit 10, the filter elements of n-times working length are removed by means of the removal drum 22.1 and cut by circular knives 27 into filter elements of lesser useful length. If these are only two circular knives, filter 12 times the useful length are cut into filter elements 4 times the length of use previously. If the upper circular blade is a circular blade and the lower one is a pair of circular knives lying one behind the other in the back plane, filter elements 16 times the useful length are cut into filter elements 4 times the length of use. Subsequently, the filter elements are 4 times the use length of a

Graduated drum 23.1 passed, in which the filter elements are staggered to be subsequently moved in a sliding / cutting drum 24.1 first transverse axial alignment, and then finally perform a further cut with a circular blade 27, the filter elements 4 times the use length in filter elements 2 times use length cuts. In the subsequent staggering drum 25.1, these filter elements are staggered, in order subsequently to be aligned in a transverse / axial alignment in a sliding / transfer drum 26.1 and then placed on a compilation drum 28.1.

There are thus placed in the soft element unit 1 0 filter elements twice the useful length. These are then passed by means of a transfer drum 29 to a compilation drum 28.2 of the soft element unit 1 1. On this compilation drum 28.2 then two filter elements are placed simple use length, which are then pulled apart axially in the spreading drum 30.1. For this purpose, reference is made in particular to FIG. 2, which illustrates the position of the respective filter elements. The soft element unit 1 1 differs from the soft element unit 10 in that a further circular blade 27 is arranged in the region of the sliding / transfer drum 26. 2 which cuts filter elements of twice the useful length into filter elements 2 of simple usable length. In addition, the soft element unit 1 1 differs from the soft element unit 1 0 in that instead of the transfer drum 29, a spreading drum 30.1 is used. The soft element units 12 and 13 also include corresponding expansion drums 30.2 and 30.3 can be pulled apart or spread apart by means of the corresponding inserted segments or filter elements.

The soft element unit 14 again essentially corresponds to the soft element unit 10, but instead of the transfer drum 29 a staggering drum 31 is used, which is essential for the invention. In this staggering drum, the assembled segments or filter elements, which are arranged in a corresponding group of 8 filter elements in this embodiment, namely 6 filter elements of simple use length and two filter elements of dual use length, are divided into two subgroups, namely staggered in this embodiment to then be aligned in the sliding drum 32 transversely aligned and compressed in a subsequent tumbling drum 33. Subsequently, the subgroups of a transfer drum 34 are transferred and accelerated by means of an acceleration drum 35, inserted into a Einlegerad 1 9 a transfer conveyor 20 so as to be transferred in a known manner in a Multisegmentfilterstrang, which is then then wrapped with filter paper and cut to length. With regard to the transfer of the groups of multi-segment filters from a transverse-axial conveying direction into a longitudinal-axial conveying direction into the strand, reference is made in particular to DE-OS

25 34 666.

The strand forming unit, which is shown schematically with 17 in Fig. 1, for example, is a conventional strand forming apparatus of the applicant with the Designation KDF 2 E.

FIG. 2 shows schematically in a three-dimensional representation two simple filter runs or filter segment runs of the tobacco-processing industry. There are two removal devices 1 provided in the form of removal drums, remove the filter rods 8 from not shown filter rod magazines or storage containers. The removal drums have a number of 60 troughs 7 for receiving the filter rods 8. The removal drums are shown here as removal ring body 100. The removal drums or removal ring bodies 1 00 rotate in the direction of the arrow about an axis of rotation 140 or are arranged on a corresponding shaft, which is not shown. The filter rods 8 are transferred from the removal devices 1 to sliding / cutting devices 3.

The respective sliding / cutting device 3 is in the form of a sliding / cutting drum, which has a sliding / cutting ring body 1 1 0 formed. The respective sliding / cutting device 3 rotates about an axis of rotation or is respectively driven in rotation on a corresponding shaft. The provided on the sliding / cutting device 3

Troughs 7 here have a number of 61 in this example. In each case, a circular blade 6 is provided in order to cut the introduced filter rods 8 into a first filter segment 9 and a second filter segment 9 '. The respective first filter segment is then on a Zusammenstellorgan

28 delivered in the form of a compilation drum, so that there two filter segments 9, 9 'are introduced in the longitudinal axial direction one behind the other into the corresponding wells 7. In the direction of rotation of the assembly member 28, there are then filter segments 9 and 9 'alternately. From there, the two filter segments 9, 9 'can be transferred for further processing, for example in a transverse axial roll winding or in a longitudinal axial strand production machine. The remaining on the sliding / cutting device 3 second filter segments 9 'are pushed to the stop 1 30, according as well as the filter rods the stop 1 30 have been pushed or are and will be delivered to the assembly drum 28 in the next run. In the remaining then empty troughs 7 filter rods 8 are again introduced.

Instead of a compilation drum 28 may also be a Zusammenstellförderband having, for example, wells 7, may be provided.

As a form of variability, for example, a removal drum 1 00 could be provided, which has 120 troughs 7, that is, whose pitch is half as large as the division of the removal device 1 shown in FIG. 2. It is also possible to provide 30 troughs, 15 troughs or a different number of troughs, which have already been mentioned above. It could, for example, also be provided that four filter segments are cut out of a filter rod 8. In this case, a number of troughs of 30 troughs having a double pitch like that shown in FIG. a double distance of the troughs, be provided. A simple interchangeability or variation possibility is given by the fact that the removal ring body 1 00 can be replaced accordingly provided with different troughs.

Fig. 3 shows schematically a filter run or filter segment run in another embodiment of the invention. The removal device 1 in the form of a removal drum runs at a slower circumferential speed than the sliding / cutting device 3 in the form of a sliding / cutting drum. In order to compensate for the speed difference, an accelerator drum 2 or staggering drum 2 is provided. At the end, the correspondingly cut filter segments are released by the sliding / cutting device 3 onto a compilation drum 28. Again, a Zusammenstellband may be provided instead of a compilation drum. In this case, it would be useful if the circular blade 6 is arranged laterally of the sliding / cutting device 3, as shown in FIG. 3, so that the assembly belt can be arranged below the sliding / cutting device 3. Fig. 4 shows another embodiment of the invention. There are two filter segment runs twice here, or two double filter segment runs are shown. The removal device 1 'comprises two removal ring body 1 00 and 1 01, both together about an axis of rotation

140 rotate. The removal device 1 'has a removal ring body

100 with 60 wells and a coaxially arranged removal ring body

101 with 40 wells on. Other numbers of troughs may be provided, as indicated above. Thus, the pitch of the withdrawal ring body 1 00 is one and a half times as small as the pitch of the removal ring body 101.
