Abstract

A filter cigarette manufacturing assembly produces double-length tobacco extrusions (115) that are cut in half and separated into two parallel lines. The gap between two adjacent cigarettes is filled by insertion of a double-sized filter. The two cigarettes are then enveloped in a cigarette paper wrapper and cut at the mid-point to form two cigarettes.

Description

The invention relates to a method for the production of filter cigarettes, cigarette rods double length are cut into cigarette rods of simple length, between these a filter plug double length is introduced, this double-length filter plug with the two cigarette rods simple length by wrapping by means of a tipping paper leaflet is connected and by a following separation cut through the double-length filter plug cigarettes normal length of use arise. Moreover, the invention relates to another method for the production of filter cigarettes. Furthermore, the invention relates to a filter attachment machine.

Under a filter attachment machine, there is provided an apparatus for producing filter cigarettes having means of receiving double length cigarette rods, means for cutting these double length cigarette rods into cigarette rods of simple length, means for inserting double length filter plugs between the cigarette rods of simple length, means for connection the double-length filter plug with the two cigarette rods of simple length by wrapping with a tipping paper sheet, which is separated by means of a cutter from a supplied tipping paper strip, with means for performing a separating cut through the double-length filter plug, so that filter cigarettes normal use length arise. If a sequence of cigarette rod filter plug-cigarette rod groups arranged transversely axially one after the other is fed as a single-lane material flow to a covering device, then this is a single-lane filter attachment machine. In a double-lane filter attachment machine, two streams of material are conveyed with articles to at least one covering device. In particular, in a two-lane filter tying machine, two lining devices are provided for one material flow in each case.

From the patents DE-C-38 05 753 . DE-C-37 06 753 and DE-C-37 06 751 There are known methods and apparatus for making filter cigarettes from cigarette rods made by double-stranding.

This shows DE-C-38 05 753 a process for the production of filter cigarettes made of double-stranded cigarette rods, in which double-length cigarette rods are guided double-lane.

DE-C-37 06 751 discloses a device for the production of filter cigarettes, which provides for two double-length processing of two double-length cigarette rods two lining feeds for two tipping paper strips for simultaneous double-lane processing.

DE-C-37 06 753 shows a method and apparatus for transferring rod-shaped articles of the tobacco processors Industry of a four-row in a double-row formation, wherein the articles are formed in the transverse axial direction.

Furthermore, in the European patent applications EP-A-895,724 and EP-A-895,725 Each method for producing filter cigarettes in a filter attachment described in which double-length cigarette rods are made double-lane. After cutting the double-length tobacco sticks the tobacco sticks simple length are continued in a staggered arrangement.

In addition, is off DE-A-196 26 679 It is known to cut and spread a single row of double length tobacco sticks and place a double length filter plug between them. The groups thus formed are fed on alternating grooves of a drum of upper and lower filter attachment devices lying substantially in the same vertical plane.

Also, in EP-A-1 108 369 a method and apparatus for making filter cigarettes is described. From a filter rod machine here tobacco sticks are arranged in pairs on conveyor drums, cut and spread, so that filter plug twice the length are each inserted between a longitudinally spaced tobacco rod pair.

In subsequent steps, the cross-axially consecutively arranged and conveyed pairs with formed tobacco rod filter plug tobacco rod groups are fed to a first coating apparatus, so that the padding apparatus of a first group of items of a pair a pad paper leaflets is attached.

Subsequently, the single-lane mass flow is divided into two partial streams, so that the particle groups provided by a tipping paper sheet are wrapped and at the same time the second article groups not yet provided with a tipping paper leaflet are fed to a second coating apparatus. After wrapping the article groups of the second partial flow with tipping paper leaflets, the double-length filter cigarettes of both partial streams produced on a conveyor drum are brought together to form a single-lane mass flow.

Based on this prior art, it is an object of the present invention to increase the production speed and productivity of a particular double-lane, Fllteransetzmaschine, the effort should be kept as low as possible.

This object is achieved by a method for producing filter cigarettes, wherein cigarette rods of double length are cut into cigarette rods of simple length, between these a filter plug double length is introduced, this double-length filter plug with the two cigarette rods simple length by wrapping by means of a tipping paper leaflet is connected and through a subsequent separation cut through the double-length filter plug filter cigarettes normal use length arise, which is further developed in that two Materlalströme with cigarette rod filter plug cigarette rod groups are conveyed side by side longitudinal axis offset, the articles of the first stream of material are provided with tipping paper and then the articles of the other material stream are provided with tipping paper leaflets.

According to the invention, a covering device is provided in each case for each material stream, consisting of a series of cigarette rod / filter-filter groups arranged one behind the other, the attachment of the lining-paper leaflets to the articles of the two material streams taking place one after the other and the material flows adjacent to one another in the region of attachment of the tipping paper leaflets be funded in parallel. It is thereby achieved that the transport paths for the tipping paper papers or tipping paper strips and the transport paths of the material streams do not intersect, so that in addition to an increase in production output, good accessibility to the articles or intermediate products at the filter tufting machine in the region of the covering devices is achieved. Compared to a single-lane filter tipping machine, the production capacity on the double-lane tipping machine is doubled if two streams of material are simultaneously transported at the same conveying speed as in the single-lane tipping machine. Moreover, it is a simplification that the material flows are guided side by side, whereby it is not necessary to supply the material streams in different ways to the respective pad means. As a result, the structural complexity is reduced to a Filteransetzmaschine because the two streams of material on the same funding, ie Fördertrommein be promoted.

Preferably, the articles of the material streams, preferably alternately, conveyed offset to one another, so that, for example, arranged on a conveyor drum between two successively longitudinally axially arranged articles of a material flow an article of the other material flow longitudinally offset axially. In this case, the articles of the two material streams are conveyed side by side alternately in the grooves of the conveyor drums.

To obtain two streams of material, the articles of material streams are formed from articles of a stream of feedstock. For example, tobacco rods of double length are transferred as a raw material flow from a single-lane cigarette rod machine to the filter attachment machine. From this single-lane flow of starting material, cigarette rod filter plug cigarette rod groups are formed as intermediates after execution of appropriate procedures, which are divided into two material streams in a subsequent step.

In particular, the streams of material are obtained by spreading the articles of feed stream, e.g. formed on a spreading drum. Here, the articles are pulled apart longitudinally apart.

In order to further increase the production efficiency of the filter tipping machine, the intervals of the articles of each material flow are shortened prior to attachment of the tipping paper leaflets, so that more articles with reduced pitch are placed on a conveyor drum. Thus, at a constant machine speed, the production speed of the filter attachment machine is increased. To ensure secure adherence of the tipping paper leaflets to the articles, the transverse axial distance between two cross-axially spaced articles of a material stream should be greater than the length of the tipping paper leaflets to be adhered.

According to an advantageous alternative embodiment of the invention it is proposed that the distances of the articles of the output current are shortened. Before two streams of material arise from the stream of starting material, the transverse axial distances of the articles or the intermediates of the stream of starting material are reduced. Since the feedstock stream is split into two streams of material, the cross-axial spacings between the articles of the feedstock stream may be less than the length of the tipping paper sheets to be adhered since the attachment of the tipping paper sheets occurs only after the feedstock stream is split into two streams of material.

In addition, it is proposed in a preferred embodiment of the invention that after the shortening of the distance, the filter plug between two longitudinally spaced cigarette rods are inserted.

In particular, the tipping paper leaflets are wrapped around the articles of the first material stream before the tipping paper leaflets for the second material flow are adhered to the articles of the second material stream. As a result, a secure wrapping of the article of the first material flow is achieved.

Further, it is preferred that the articles of material streams after wrapping are combined with the respective tipping paper leaflets into a material stream so that the manufactured cigarette rod filter plug cigarette rod groups of both material streams are cut at a cutting device on a conveyor drum into filter cigarettes of normal use length.

In addition, it is particularly advantageous if the articles of the first and second streams of material are conveyed with a larger transverse axial distance between the articles than the articles of the output stream.

• aus den Artikelkomponenten des ersten Teilstroms und aus den dem ersten Teilstrom zugeführten komplementären Artikelkomponenten werden Filterzigaretten hergestellt, während die Artikelkomponenten des zweiten Teilstroms gefördert werden,

As an alternative solution to the problem, a method for the production of filter cigarettes is proposed, wherein two partial streams are provided with article components or articles of the tobacco-processing industry and the following process steps are carried out:

• filter cigarettes are produced from the article components of the first partial stream and from the complementary article components supplied to the first partial stream, while the article components of the second partial stream are conveyed,
• After the filter cigarettes are made from article components of the first part stream and the complementary article components fed to the first part stream, filter cigarettes are made from the article components of the second part stream and complementary article components fed from the second part stream.

Article components are understood to mean articles which are part of a filter cigarette. According to the invention, constituents put together in a partial flow, ie article components, are provided for further processing into a filter cigarette. Complementary article components are understood to mean the supplemental components for a filter cigarette so as to complement the article components and the complementary article components and a filter cigarette of single or multiple length result.

The invention is based on the idea that filter cigarettes are produced in succession on a conveyor track on a multi-lane filter attachment machine, while the article components are transported on another conveyor track parallel to the production of filter cigarettes on the first conveyor track. Following this, the article components with supplementary, d. H. complementary, associated article components, so that filter cigarettes are also produced on the second web. Thus, at the same time a manufacturing process of filter cigarettes and a transport process of article components or manufactured filter cigarettes take place on a filter attachment machine. This decoupling of a manufacturing process of filter cigarettes and a transport process of zugeförderten article components is made in a first process section.

For this purpose, it is advantageous that, during the production of the filter cigarettes from articles of the second partial flow and the complementary partial components supplied to the second partial flow, the filter cigarettes produced from the articles of the first partial flow and the complementary partial components supplied to the first partial flow are conveyed, in particular positionally neutral. As a result, in a second method step, a decoupling of a transport process of the filter cigarettes produced in the first method step from the production process of filter cigarettes from the article components of the second partial stream is likewise achieved. By doubling the manufacturing processes, the production capacity of a filter attachment machine is increased. For this purpose, the production and transport routes of the article components or manufactured filter cigarettes are parallelized. When Another advantage has been found that the transport paths of the complementary article components do not intersect, so that a good accessibility of the conveying elements or functional units, such. As tiling paper apparatus is achieved.

According to an advantageous embodiment of the invention, it is proposed that the article components of the second partial flow are promoted positionally neutral during the production of filter cigarettes with the article components of the first partial flow. Position-neutral promotion of articles is understood to be the exclusive promotion of the articles, whereby the article components are promoted unchanged, d. H. the article components are not cut or pushed during transport or otherwise processed or processed.

In a correspondingly advantageous manner, the article components of the second partial flow are conveyed positionally neutral during the production of filter cigarettes with the article components of the first partial flow. Thus, the article components of the second partial flow are transported exclusively, without changes or processing or examination of the article components takes place. Position-neutral transport is understood to mean exclusively the pure transport of the article components or of the manufactured filter cigarettes.

By means of a filter attachment machine operated according to the above-described method according to the invention, it is possible to produce two cigarette brands independently of one another simultaneously and parallel to one another on the same machine. Furthermore, the method or the filter attachment machine allows cigarettes to be produced in the other production section if one production branch fails in one production section become.

According to a preferred embodiment of the invention, both the article components of the first partial flow and the filter cigarettes produced with the article components of the first partial flow and the article components of the second partial flow and the filter cigarettes produced with the article components of the second partial flow are each conveyed along a separate conveying path. As a result, a separation and decoupling of the manufacturing processes from the conveying paths or transport paths of the article components or filter cigarettes according to the invention is carried out.

In addition, it is proposed that, on the one hand, the article components of the first partial flow and the filter cigarettes produced with the article components of the first partial flow and, on the other hand, the article components of the second partial flow and the filter cigarettes produced with the article components of the second partial flow are juxtaposed and / or with one another, i. offset from one another, be promoted. Thus, the manufacturing processes and transport processes are spatially and structurally clearly separated.

A further advantageous embodiment of the invention provides that the filter cigarettes are transferred after production with the article components of the first partial flow and the article components of the second partial flow to at least one common intermediate conveyor, whereby a modular construction of a filter attachment machine is possible. By the common intermediate conveyor the conveying paths of the article components of the second partial flow and the filter cigarettes are crossed with the article components of the first partial flow, wherein the manufactured Filter cigarettes are performed with the article components of the first partial flow in a transport plane and at the same time the article components of the second partial flow are brought into a production level.

For this purpose, it is provided that the conveyor paths of the filter cigarettes produced with the articles of the first partial flow and the articles of the second partial flow are combined and / or crossed at the intermediate conveyor device.

Furthermore, it is provided according to the invention that the filter cigarettes are transferred with the article components of the first partial flow and the filter cigarettes with the article components of the second partial flow after their preparation to a common transfer device. Thus, the transport levels for the filter cigarettes are combined with the article components of the first partial flow together with the filter cigarettes with the article components of the second partial flow, so that the filter cigarettes are transferred to other conveying organs, where the processing of the produced filter cigarettes (eg the test is carried out.

Preferably, filter cigarettes of multiple, especially double, use length are produced.

In particular, the filter cigarettes multiple use length are cut into filter cigarettes simple use length, it being possible in the invention, that the filter cigarettes are cut immediately after their preparation or only when merging the partial streams.

in each case one embodiment of a transfer device with an arrangement of the drums (upper area) and a schematic functional sequence (lower area).

In the following figures, identical or similar elements or corresponding parts are provided with the same reference numerals, so that a corresponding renewed idea is dispensed with.

In Fig. 1, the view of a double-lane Filteransetzmaschine 10 is shown schematically. The schematic functional sequence is shown in FIG. 2.

The Filteransetzmaschine 10 receives double-length tobacco sticks 15 from a cigarette rod machine, not shown here. For this purpose, the tobacco sticks 15 are taken over by the cigarette rod making machine by means of a transfer drum 11 and transferred via a conveyor drum 12 to a conveyor drum 13.

During their promotion on the conveyor drums 12, 13, the Queraxialen distances of the tobacco sticks 15 are shortened, wherein the transfer of the tobacco sticks 15 from the conveyor drum 13 to the conveyor drum 14, the distances of the tobacco sticks 15 in comparison to the distances of the tobacco sticks 15 on the conveyor drum 11th are halved. The shortening of the transverse axial distances of the article 15 is also referred to as pitch reduction or deceleration.

On the conveyor drum 14, the double-length tobacco sticks 15 are cut in the middle to tobacco rods 115 simple length and delivered to a spreading drum 21, which causes a longitudinal axial distance between the longitudinally aligned tobacco rods 115 simple length by spreading the article 15.

Subsequently, the spread tobacco sticks 115 of simple length from the conveyor drum 21 to a compilation drum 22 pass. Furthermore, an insertion drum 24 for filter plugs 25 (FIG. 2) of double use length is arranged on the assembly drum 22 so that a double-length filter plug 25 is inserted from the insertion drum 24 between two tobacco rods 115 axially longitudinally spaced apart. The insertion drum 24 receives filter plug 25 double-use length of a filter feeder 100, which has two staggered filter magazines 110, 120 has. In the European patent application with the file reference 03005286.4 a device for filter feed to a filter attachment machine from two mutually offset filter magazines is described and is fully incorporated into the present patent application.

After assembly of the cigarette rod filter plug cigarette rod groups on the assembly drum 22, the group articles are transferred to a spreading drum 23, each second article of the articles arranged one behind the other being allocated to a mass flow M1, M2. In this case, the two mass flows M1, M2 arise from the single-lane flow of starting material with the cigarette rod filter plug-cigarette rod groups arranged one behind the other and transversely axially. For this purpose, the spreading drum 23 and all other conveyor drums are approximately twice as wide as the conveyor drums for the one-lane feedstock stream from the transfer drum 11 to the assembly drum 22.

In an alternative not shown here, two mass flows are transferred from a cigarette rod machine to the filter attachment machine.

After splitting the feedstock stream into two streams of material M1, M2, the two material streams M1, M2 are transferred to a conveyor drum 31, wherein on this conveyor drum 31, the articles of the two streams of material are transported in parallel and side by side. Here, the Queraxialen distances between the articles of each material flow M1, M2 are twice as large as the distances of the finished assembled article groups on the assembly drum 22. Due to the longitudinal axial spread of the article on the spreading drum 23 is a sufficient transverse axial distance between the article each material flow M1, M2 so that tipping paper leaflets are securely adhered to the individual cigarette rod filter plug cigarette rod groups without a tipping paper leaflet touching a second group of articles.

An alternative to the longitudinal axial spreading and pulling apart of the material streams can also be achieved by means of a turning device with e.g. two turning or conical drums are realized.

On the conveyor drum 31, the articles of the two mass flows M1, M2 are arranged alternately in the receptacles or grooves of the conveyor drum 31. From the conveyor drum 31, the articles of the two mass flows M1, M2 are indicated on a conveyor drum 32, so that tamping paper leaflets 55 (FIG. 2) are attached to the articles of the first mass flow M1 by a coating apparatus 50. After the transfer of the two mass flows M1, M2 to the conveyor drum 33, the articles of the first mass flow M1 are wrapped by the tacked tipping paper leaflet 55, while the parallel conveyed articles of the second mass flow M2 have not yet received any tipping paper leaflets.

After further transport of the two mass flows M1, M2, the articles of the second mass flow M2 on a conveyor drum 34 are each provided with a tipping paper leaflet 65 (Figure 2) by a second tipping apparatus 60.

Subsequently, the articles of the second mass flow M2 are completely wrapped by the tipping paper leaflets 65, while the articles of the first material flow M1 are transported parallel to the articles of the second material flow M2 on the same conveying drums 34, 35.

After wrapping the articles of both mass flows M1, M2 are on a conveyor drum 36, the two mass flows joined together by longitudinal axial telescoping, so that the single-lane sequence of wrapped cigarette rod filter plug cigarette rod groups on a cutting drum 41 in the middle of the double-length filter plug are cut so that filter cigarettes 225 simple use length (Fig. 2) arise. Subsequent to the cutting drum 41, the cut articles 225 are pulled apart on a spreading drum 42 and delivered on subsequent conveyor drums 43, 44 testing devices for the filter cigarettes 225.

By dividing the stream of starting material into two streams M1, M2, two streams are provided with article components of filter cigarettes to be manufactured, the article components comprising cigarette rod filter plug cigarette rod groups in the embodiment of FIG. A synonymous term for cigarette rod is the term tobacco rod.

The sub-streams M1, M2 are supplied as a complementary article components each covering paper leaflets 55, 65 separately and adhered. First, the tipping paper leaflets 55 are adhered to the groups of article components of the sub-stream M1, thus that filter cigarettes with the article components of the first partial flow M1 on the conveyor drum 33 are subsequently produced from the article groups consisting of cigarette rod filter plug cigarette rod groups together with the complementary article components, in the present case covering paper leaflets. At the same time, the article components of the second partial stream M2 are conveyed in neutral position on the conveyor drums 31, 32, 33.

Following the manufacture of the filter cigarettes with the article components of the first sub-stream M1, the article components of the second sub-stream M2, i. Cigarette rod filter plug cigarette rod groups, each covering paper leaflets 65 attached as complementary article components of a double use length filter cigarette to be produced, so that subsequently filter cigarettes are produced with the article components of the second partial stream M2 on the conveyor drum 35. At the same time, i. During the manufacture of the filter cigarettes from the article components of the second partial flow M2, the filter cigarettes produced in the first section of the filter attachment machine are transported on the conveyor drums 34, 35 with the article components of the first partial flow M1. The combination of the manufactured filter cigarettes with the article components from both partial streams M1, M2 takes place on the conveyor drum 36. Subsequently, the filter cigarettes double use length produced on the cutting drum 41 are cut centrally, so that filter cigarettes normal or simple use length arise.

In the embodiment gem. Fig. 2 and Fig. 1, the article components of the two partial streams on the same conveyors after provision of the two partial streams M1, M2 side by side and transported parallel to each other, wherein the article components of the two partial streams M1, M2 offset from each other or alternately to each other on the conveyor drums or conveyors are arranged.

FIG. 3a shows a schematic view of a further double-web filter tying machine 10. The corresponding schematic functional sequence is shown in FIG. 3b.

At the filter attachment machine 10, the double-length tobacco rods are cut into tobacco rods of simple length on a double-width cutting drum 130. The two streams or streams of tobacco rods are next to each other, d. H. parallel to each other, arranged on the cutting drum 130 and are transferred to a transfer drum 131. The transfer drum 131 is further formed as a spreading drum, so that the cut tobacco rod pairs of each sub-stream are spread longitudinally axially to subsequently insert a filter plug of double length between a longitudinally spaced tobacco rod pair.

At the transfer point of the article components to the other conveyors article components for the production of manufactured filter cigarettes for further processing are provided in accordance with the invention. The transfer drum 131 transfers the article components of the first partial flow M1 (see FIG. 3b) as longitudinally-spaced pairs of tobacco rods to an assembly drum 151. Double-length filter plugs are inserted on the assembly drum 151 between the longitudinally-spaced article components of the partial flow M1.

The compilation drum 151 is part of a filter feed 150, which provides double-length filter plugs for the article components of sub-stream M1. The filter plug twice the useful length of the filter feed 150 are understood in the context of the invention as complementary article components.

Simultaneously and at the same time, the article components of the second partial flow M2 (see Fig. 3b) are conveyed from the transfer drum 131 to a further conveyor drum 132 to a conveyor belt 140. The article components of the second partial flow M2 transferred to the conveyor belt 140 (see Fig. 3b) are neutral in position as longitudinally axially spaced tobacco rods or pairs of tobacco rods on the conveyor drum 140, ie. H. without processing the article components, transported.

On the assembly drum 151 filter plugs are inserted between the longitudinally axially spaced article components of the first partial flow M1 and the longitudinally axially spaced tobacco rod pairs and transferred together to a subsequent conveyor drum 152.

On the conveyor drum 152, the formed tobacco rod filter plug tobacco rod groups are provided with a pad paper leaflet as a further complementary article component of a pad 50, which are subsequently rolled on the conveyor drum 153 to double use length filter cigarettes. Subsequently, the double-length filter cigarettes are transferred to a cutting drum 154, so that the double-length filter cigarettes are cut with the article components of the first partial stream M1 to filter cigarettes simple use length. Thereafter, the cut filter cigarettes are transferred from the cutting drum 154 to an intermediate conveyor 200.

The intermediate conveyor 200 consists of several drums and also cooperates with the conveyor 140. The intermediate conveyor 200 is described in detail below in FIGS. 4a, 4b.

The filter cigarettes transferred from the cutting drum 154 with the article components of the partial stream M1 form the partial stream M1 ', which is transferred to the intermediate conveyor 200.

For the intermediate conveying device 200, the article-neutral conveyed article components M2 are also conveyed by the conveyor belt 140.

By means of the drum arrangement of the intermediate conveying device 200, the article components or tobacco rod pairs of the partial stream M2 conveyed on the conveyor belt are transferred to a compilation drum 161 of a filter feed device 160, while the produced filter cigarettes are transferred to the conveyor belt 140 as part stream M1 'with the article components of the first subflow M1. The manufactured filter cigarettes are conveyed on the conveyor belt 140 to a common transfer device 300. The transfer device 300 is shown in FIGS. 5a, 5b and described below.

The transferred from the intermediate conveyor 200 from the conveyor belt 140 to the assembly drum 161 article components of the second partial stream M2 are provided with filter plugs twice the length and subsequently provided on a conveyor drum 162 each with a tipping paper from a pad 60 and transferred to a conveyor drum 163 at which the article components and the complementary article components (Filter plugs and tipping paper leaflets) are rolled into double-length filter cigarettes. Subsequently, the double-length filter cigarettes are cut with the article components of the second partial stream M2 on the cutting drum 164 and transferred to a transfer device 300 as a partial stream M2 '.

In the embodiment shown in Fig. 3a and 3b are provided as article components of the partial streams M1, M2 spaced tobacco rod pairs, which are produced together with supplied complementary article components, in the present case double-length filter plugs and tipping paper, each to filter cigarettes multiple or simple use length. For each partial flow, a separate filter feed device 150 or 160 and a separate coating device 50 or 60 are respectively provided. In the first section of the filter attachment machine 10, filter cigarettes are produced from the article components of the first sub-stream M1, while the delivery of the article components of the other sub-stream M2 takes place on the conveyor belt 140.

In an alternative embodiment, the delivery of the article components of the second partial stream M2 can be carried out on conveyor drums or other conveying members.

It can be seen from the functional sequence in FIG. 3b that the partial flows M1, M2 or M2 and M1 'are conveyed side by side. The conveying paths of the partial flows M1, M2 or M2, M1 'run side by side (viewed from above), with the conveying paths at the intermediate conveyor 200 crossing each other.

In an embodiment not shown here, it is possible that the conveyor belt 140 below the conveyor drum 151, 152, 153, 154 and the conveyor drum 161, 162, 163, 164 runs, so that the subsidized article components or filter cigarettes are arranged one below the other.

The transferred to the transfer device 300 articles of the two streams M1 ', M2' or produced filter cigarettes are transferred to a conveyor drum 170, are arranged on the side by side filter cigarettes simple use length spaced. From the conveyor drum 170, the filter cigarettes are conveyed to other testing equipment or processing facilities.

In a further, not shown here Filteransetzmaschine 10 compared to the Filteransetzmaschine shown in Fig. 3a instead of a Filterzuführeinrichtung at least two Filterzuführeinrichtungen each provided for a partial flow, wherein a multi-segment filter plug with multiple filter pieces are supplied to the article components of the partial streams.

For this purpose, it is conceivable that instead of a feed device 150 or 160 several Filterzuführmodule are provided by means of which filter pieces between the spaced article components of the two partial streams M1, M2 are inserted, so that a total of a double-length filter plug from the supplied filter pieces of Filterzuführmodule arises. In this case, the supplied filter pieces of a filter plug are also understood as a complementary article component in the inventive sense.

FIGS. 4a and 4b each show an embodiment of an intermediate conveyor device 200 according to the invention, with a view of the drums being shown schematically in the upper area and a functional sequence in the lower area are.

In the embodiment in Fig. 4a, the intermediate conveyor 200 has a conveyor drum 201, the filter cigarettes simple use length of the cutting drum 154 receives. The filter cigarettes simple use length form the partial stream M1 'with the filter cigarettes formed from the article components of the partial stream M1. The filter cigarettes of the partial flow M1 'are subsequently transferred to a transfer drum 202, which transfers the filter cigarettes to the conveyor drum 203 arranged therebelow. At the same time, the filter cigarettes are moved longitudinally axially on the conveyor drum 203, so that the filter cigarettes are placed as part of the stream M1 'on the conveyor belt 140 and spatially offset.

In the embodiment shown in Fig. 4a, the partial streams M1 '(filter cigarettes) and M2 (spaced tobacco rod pairs) are transported side by side and spatially with each other. This can be removed in the lower part of FIG. 4a. The article components of the second partial stream M2 conveyed on the conveyor belt 140 are received by the conveyor drum 203 and moved longitudinally axially, so that the article components of the second partial stream M2 are transferred to the conveyor drum 202. Subsequently, the spaced-apart article components of the second sub-stream M2 are transferred to an assembly drum 161 (Figs. 3a, 3b). The fact that the partial streams M1 'and M2 are conveyed side by side, the manufactured filter cigarettes and conveyed article components must be moved longitudinally axially.

FIG. 4b shows an embodiment of an intermediate conveyor 200, wherein the partial streams M1 'and M2 are interconnected (in the vertical plan view, see lower portion of Fig. 4b) are promoted. In this embodiment, the filter cigarettes or article components need not perform a longitudinal axial displacement.

In Fig. 5a, an embodiment of a transfer device 300 according to the invention is shown, wherein in the upper part of a view of the drum assembly and at the bottom of a functional sequence are shown schematically. FIG. 5 b shows a further exemplary embodiment of a transfer device 300.

In the execution acc. 5a, the partial flows of the manufactured filter cigarettes M1 ', M2' are conveyed parallel and offset from one another. The cut filter cigarettes of the upper and second partial flow M2 'are transferred to a conveyor drum 301, which transfers the filter cigarettes to the conveyor drum 302. From the conveyor belt 140 (FIGS. 3a, 3b), the filter cigarettes of the first partial flow M1 'are picked up by the conveyor drum 303 and transferred to the common conveyor drum 302. On the conveyor drum 303, a portion of the filter cigarettes of simple use length performs a longitudinal axial displacement. At the same time, the filter cigarettes of the second sub-stream M2 'are also partially displaced, so that two sub-streams to the transfer drum 170 arise when transferring the filter cigarettes simple use length, the tobacco sticks of the filter cigarettes facing outwards and the filter plug inside.

In the exemplary embodiment in FIG. 5b, the filter cigarettes of the two partial flows M1 ', M2' are guided perpendicular to one another (compare FIG. 4b). When transferring the filter cigarettes of the partial flow M1 'to the conveyor drum 303, the filter cigarettes are spaced longitudinally axially. The filter cigarettes of the second partial flow M2 'become on the conveyor drum 302 moved longitudinally axially, so that when transferring the filter cigarettes of the two partial flows to the conveyor drum 170 two partial flows are provided with filter cigarettes simple length.
