The same reference numerals are used in the following figures used for the same or corresponding characteristics been, so that from a new presentation each is disregarded.

Fig. 1 shows a cross-sectional view of a transfer station. A sleeve 11 arranged in a trough of a sleeve feed drum 10 and having a first filter material 19 in the center is brought into the area of a transfer station. The same applies to a filter plug 20 , which can consist, for example, of cellulose acetate. The filter plug 20 has a length of 8 mm, for example. The filter plug 20 is by means of a filter plug För derers 21 , z. B. a filter plug drum, in which the corresponding filter plugs 20 are received in receptacles, a plug receptacle 25 .

In a continuous process step, which is shown in Fig. 2, the filter sleeve 11 is in engagement with the transfer station and is held in the specified position by means of vacuum bores 13 which are arranged on a conveyor drum. A plunger 18 has also already been introduced into the filter sleeve 11 from below. Furthermore, the plug 20 , which is conveyed by the fil terstöpfel conveyor 21 , has been transferred to the transfer unit and is held in the position shown in FIG. 2 by means of a further vacuum bore 13 . Furthermore, two different granules, namely a first granulate 26 and a second granulate 27 are filled into bores 14 of a slide 24 provided therefor. The amount of granules is given by the size of the bore.

The slide 24 is designed to be displaceable in the drawing plane from left to right and vice versa.

Fig. 3 shows a cross-sectional view of the transfer station, the plunger 18 has been moved vertically further upward, so that the sleeve 11 is essentially flush with the upper edge of the conveyor drum 12 with its upper end. Furthermore, the plug 20 has been conveyed by means of the plunger 17 in the axial direction of the plunger, that is to say vertically downward, into the tube 15 and into a first bore 14 in the slide 23 . A circular knife 28 , which is guided in the guide 29 , cuts the stopper 20 exactly at the upper edge of the slide 23 into two equally large stoppers, each 4 mm long. To convey the plug 20 into the tube 15 and the sleeve 11 in the feed drum bore 16 , the vacuum or suction air in the vacuum bores 13 is turned off.

In a next step, which is shown in Fig. 4, the slide 23 is pushed to the left ge, so that the upper part of the split plug 20 is aligned with another bore 14 of the slide 23 vertically. In a further method step, which is not shown, the plug 20 is transferred into the further bore by means of the plunger 17 , and a further filter plug 30 , which is made of another material, such as nonwoven, which is enriched with a granulate, is supplied by means of a Cut circular knife and inserted into the two remaining bores 14 of the slider 23 . In FIG. 5, the process state is accurately represented, in which the further filter plug was inserted into the remaining bores 30.

In Fig. 5 is also a bore of the slider 23 , in which there is a filter plug 30 and a bore of the slider 24 , in which there is granules, aligned with the conveyor drum bore 16 or the sleeve 11 , so that in a next Method step, which is shown in Fig. 6, the plunger 17 can insert the filter material 30 and 26 into the filter sleeve 11 . Instead of, as was shown in FIG. 6, it is possible to insert the filter material 30 and 26 only up to the upper edge of the filter plug 11 , so that the or the degree of movement of the plunger 17 can still be minimized.

In Fig. 7 the process state is shown in which, after appropriate alignment, a drilling tion in which a filter plug 20 is arranged and a bore of the slide 24 , in which the granules 27 are arranged, aligned with the sleeve 11 , so that the plunger 17 could insert the material.

In Fig. 8, the process stage is shown, in which the sleeve 11 , which was half-filled with filter material, was conveyed down by lowering the plunger 18 and again in the effective range of the vacuum bore 13 , so that the sleeve 11 again this vacuum bores and in accordance with the recordings provided in the Fördertrom mel 12 is held. As the next step, the half-filled sleeve is fed to a turning drum, in order to then subject the sleeve, which has been turned through 180 °, to the same process steps, so that a total of five times the filter can be produced twice the length of use. In this exemplary embodiment, this five-fold filter then comprises five different filter materials, which are arranged in segments in the filter. This is a first filter material 19 , which for example has a length of 8 mm after cutting through the filter twice the length of use, a first granulate 26 with a height of approx. 8 mm, a second filter plug 30 with a height of 4 mm or a thickness of 4 mm, a second granulate 27 with a height of approximately 8 mm and a final filter plug 20 with a thickness of 4 mm. In the context of this invention, it is also possible to use filter plugs down to a thickness of 2 mm, so that even more filter materials can be arranged in segments in the filter sleeve 11 .

FIG. 8 also shows a discharge drum 50 which conveys the half-filled sleeve 11 to a turning drum, which is not shown in FIG. 8. The sleeve is then turned through 180 ° in this turning drum and then fed back to the conveyor drum 12 by means of a feed drum in order to fill the rest of the sleeve 11 .

In the context of this invention, it is also possible to turn the sleeves several times in order to introduce different filter materials at several stations. It is therefore not necessary for each half of the sleeve 11 to be completely filled in a transfer station before it is rotated.

Fig. 9 shows a further embodiment of a transfer device according to the invention, in which four different filter materials can be transferred into the sleeve simultaneously. The sleeve also consists, for example, of a paper sleeve 37 . In order to pass four different materials, a third slide 41 and a fourth slide 42 are provided in addition to the first slide 23 and the second slide 24 . For example, a soft element 30 is inserted into the third slide 41 and a granulate 26 into the fourth slide 42 .

It is also possible within the scope of this invention to increase the number of bores of the slide 24 of the embodiment examples of FIGS. 1 to 8 to four, so that four bores are filled with the appropriate granules and so that no further granulate filling after turning or Turning the filter sleeve around is necessary. Corresponding filter plugs 20 and 30 are already stored in the exemplary embodiments in FIGS. 1 to 8, so that after one side of the filter sleeve 11 has been filled, no further filter plugs need to be inserted into the slide 23 . The same is of course also in accordance with the embodiment. Fig. 9 possible.

In the upper region of FIG. 10, a side view of a cross-sectional representation of a granulate feed station or a granulate portioning station is shown. There are two eccentrically arranged disks, namely a first disk 31 and a second disk 32 are Darge, the first disk 31 being arranged above the second disk 32 . A top view of this device is shown in the lower area of FIG. 10. Both disks, 31 and 32, have holes 14 . Granules 26 are filled into the bores. For this purpose, granules 26 are fed in by means of a granule filling device 51 . The first disc 31 rotates counterclockwise over the disc 32 , which also rotates counterclockwise in this embodiment. Sleeves 11 are arranged on the second disk 32 below this disk. These are held in the appropriate places by means of conventional holding members. The portioned granules predefined by the size of the bores migrate counterclockwise in the direction of an insertion zone 38 a- 38 b. The filter sleeves 11 arranged below the second disk 32 move in the same way. In the insertion position 38 , the bores of the two disks are aligned. Due to gravity, granules are introduced into the sleeves, as indicated in the upper part of FIG. 10. The inventive and preferred granulate feed station or portioning station provides a particularly simple implementation of the portioning of granules and the introduction of granules into filter sleeves. Due to the large feed zone 38 a- 38 b, the disks 32 and 31 can rotate at high speed and the production speed is correspondingly high.

In Fig. 11 a schematic plan view is shown on a Filterherstellmaschine. However, the processing stations are not shown in FIG. 11, which are shown for example in FIGS. 1 to 9, that is to say those which are provided for the introduction of the filter elements.

The various processing steps are carried out on a single main drum 100 . A Hülsenmas senstrom 101 leads sleeves 114 4 times the length of use to the filter manufacturing machine. In the area of a transfer drum 103 , which is not shown, the filter sleeves cut 4 times the length of use in the middle and moved axially. By means of a transfer cone drum 104 and a transfer drum 105 , the z. B. corresponds to the sleeve feed drum 10 of FIG. 1, the supplied sleeves of the main drum 100 , the z. B. corresponds to the conveyor drum 12 of FIG. 1, supplied.

A filter element mass flow 102 feeds filter elements 12 times the processing length of the filter manufacturing machine. These are cut into shorter sections at a location that is not shown. By means of a transfer cone drum 104 which, for. B. the filter plug conveyor 21 corresponds to FIG. 1, the filter elements or the already cut filter elements 116 are fed to a transfer drum 105 , on which they are further divided by means of a circular knife 106 . In the filter manufacturing machine three corresponding organs are shown, by means of which filter elements of appropriate length, each of which can have different properties, can be supplied. In the two filter element feed stations arranged below, transfer cone drums 107 for transferring the filter elements are shown.

A first storage container and a second storage container for a first granulate 110 and a second granulate 111 are provided. The granules are fed via appropriate conveying elements to a granulate transfer station 112 , in which, for example, corresponding bores of slides can be completely filled with the desired granules. The main drum 100 moves clockwise. Before half of a complete revolution of the main drum 100 has ended, for example, one side of a multiple filter of double use length has been completely filled. This half-filled multiple filter is conveyed by means of a transfer drum 109 to a turning drum 108 in order to be turned there and to be fed back to the main drum 100 by means of a further transfer drum 109 . The further fillings are then carried out in the remaining circulation of the main drum 100 . However, the other filling elements are also not shown in FIG. 11. Shortly before the end of a full rotation of the main drum 100 , the fully filled or partially filled multiple sleeves or multiple filters of double use length are converted into a double multiple filter mass flow 117 , i.e. a multiple filter mass flow, by means of a transfer drum 109 and corresponding transfer cone drums 104 and a transfer drum 103 , wherein the multiple filters have a double working length. With 118 a double multiple filter is shown. Furthermore, a control cabinet is shown by reference numeral 113 , which controls the filter-Her machine. In this embodiment of the invention, a single main drum 100 is shown, in which all processing steps for filling filter sleeves 11 can be carried out. Shortly before the finished filled sleeve is removed, a heating element can preferably be provided which can be brought into engagement with the corresponding sleeves in order to cause hot-melt adhesive which was applied to the inside of the paper sleeve in a previous method to stick, so that the introduced filter materials remain in their positions.

Fig. 12 is a schematic illustration showing another embodiment of the invention. Filter sleeves 11 are fed to a conveyor drum 12 by means of a sleeve feed drum 10 . This is also shown schematically in FIG. 13 at position a). In b) the sleeve 11 is moved a little further upwards and the plunger 17 also. In the course of e), the ram is moved upward. At f) filter plugs 20 are fed by means of a filter plug conveyor 21 , which in this exemplary embodiment is a drum. This is also shown schematically in FIG. 13 at f).

In the schematic representation of FIG. 13, sleeves and plungers adjacent from f) to m) are shown. 13 f) and g) must therefore be considered together in the schematic representation of FIGS . In a next process step h) and i), the plungers 17 are moved downwards, whereby the filter plug 20 , which is located at h), is also moved downwards. At j) and k) the filter plug 20 is divided into two parts by a circular knife 28 . The upper part of the plug 20 is located in a receptacle or bore in a lever 35 . At l) and m) the lever 35 is pivoted ver so that its bore is flush with the underlying bore of the main drum or conveyor drum 12 , in which the sleeve 11 is located. From now on, the process steps are again shown individually. In n) to q), the plunger 17 moves into the opening in which the sleeve 11 is located and brings the corresponding filter material into this sleeve. At r) and t), the plunger 17 moves out of this opening again. At s) the lever moves back to its starting position. The sleeves 11 thus partially filled are removed by means of the removal drum 33 . Filter sleeves with filter elements 34 are then located in the receptacles of this removal drum 33 . It is also possible within the scope of this invention or this embodiment to fill an entire half of the sleeve 11 . However, only the variant of a lever instead of a slide is shown in FIGS. 12 and 13, by means of which corresponding filter plugs can be moved. It is also possible to use several levers 35 , in which granulate can then be introduced, for example, or to use a combination of levers and sliders.

In Fig. 14, a modular construction is one. Filter-Her setting machine shown. The modules sleeve feed module 130 , granulate and soft element filler module 131 ( 2 ×) and turning module 132 are shown. In this embodiment, sleeves are inclined by means of a sleeve 120 and filter elements by means of two filter elements 121 . The sleeve feed module thus comprises a supply of sleeves from a sleeve slant 120 , a take-up drum 123 and a transfer drum 124 . The transfer drum 124 conveys the sleeves from the take-off drum 123 to a dispensing drum 125 , which in turn conveys the sleeves to a granule drum 126 . Arrived in the granulate drum 126 , the granulate is filled into the sleeves. Here, for example, a device according to find the Fig. 10 use. The sleeves, some of which are filled with granulate, are then transferred to a lever drum 127 , which, for example, is designed according to FIG. may optionally be of Fig. 12. In this module, namely in the granulate and soft element filler module 131 , filter elements are inclined 121 filter elements via a removal drum 123 and a feed and sleeve removal drum 128 of the lever drum 127 .

By means of the feed and sleeve removal drum 128 , the sleeves filled with granulate and corresponding filter elements such as soft elements, one side of which is now completely filled in this exemplary embodiment, are removed and transferred to a transfer drum 124 which is arranged in the turning module 132 . The transfer drum 124 transfers the half-filled sleeves 11 to a turning drum 129 in which the sleeves are turned. On the way to the turning drum, the sleeves can be subjected to heat to activate a hot glue track that fixes the filter elements. After the sleeves have been turned over, the half-filled sleeves are transferred to a further granule and soft element filler module 131 by means of a delivery drum 125 , which transfers the sleeves to a granule drum 126 , in which the sleeves are again filled with granules. Next, the sleeves are transferred to a lever drum 127 , in which the sleeves are filled with another soft element. The soft elements are in this case from a Fil terelementschragen 121 via a take-off drum 123 and a feed and sleeve removal drum 128 of the lever drum 127 passed. The now fully filled sleeves are then passed through the drum 128 to a transfer drum mel 124 , at which a heating station 39 is arranged, by means of which, for example, a hot glue can be activated continuously or in the remaining part of the sleeve.

A fully filled double multiple filter 118 is shown in longitudinal section on the left side of FIG. 14, which is composed of a first filter material 19 , a granulate 26 and a filter plug 20 in each case. This double multiple filter is cut in the following cigarette manufacture in the middle of the first filter material 19 .

In Fig. 15, another exemplary embodiment of a filter manufacturing machine is shown, by means of which a double multiple filter 118 can be produced, each consisting of four different filter elements of double use length. Two different types of granulate 26 and 27 have been introduced into this double multiple filter 118 . In order to insert a further granulate, in comparison to the embodiment in FIG. 14, two further granulate modules 133 are added to the filter manufacturing machine in FIG. 14. These are between the sleeve feed module 130 and the granule and soft element filler module 131 as well as the turner module 132 and the further granule and soft element filler module 131 . Otherwise, the elements that are used here are corresponding.

It is with the filter manufacturing machine according to the invention possible, modular according to the wishes of the corresponding To manufacture customer filters. To do this, only the corresponding modules exchanged with each other, be added or removed.

Although essentially manufacturing variants were shown in the description of the figures, in which a vertical alignment of filter sleeves 11 has been used, it is also possible to align them horizontally. Furthermore, the invention is not limited to the use of corresponding drums, but it is also conceivable to use trough belts for transporting and processing the filters, as for example by DE 197 08 836 A1 or US Pat. No. 6,079,545 by the applicant, DE 39 25 073 A1 and US 5,209,249 from G. D Societa 'per Azioni, Italy, or EP 1 048 229 A2 from Focke.

The filter manufacturing concept is geared towards Filter plugs made of different filter materials and / or granules in changing composition in  Introduce filter sleeves and to multi-segment filters or Process multiple filters. As part of this inven The term "filter materials" also includes the Term "granules".

Use preferably at least twice long, prefabricated filter sleeves with a loose or firmly glued filter element in the middle. 8 mm plugs are usually transported, which are then divided into 4 mm long plugs. In a somewhat modified concept that corresponds to the embodiment according to. Fig. 11 is modified, the filter sleeve is held in a trough of a carousel or the main drum 100 and passed on from station to station by rotating the main drum 100 . The stations are, depending on the design of the filter, also in changing order, a sleeve feed device, a granulate metering device with a granule feed station and a filter plug feed device, a filter turning device and again a granule feed device with a granule feed station and a filter plug feed device or just a granule feed device and a filter feed device. Except when turning, the sleeve is always held in the same location in the main drum 100 . When filter material is fed into the sleeve or when this material is introduced into the sleeve, the sleeve is preferably held in its position by vacuum or suction air. The sleeve holder can be provided with vibrations, for example, so that granules can be introduced in the densest possible packing.
