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 is a device for the production of filter cigarettes with means for receiving cigarette rods of double length, with means for cutting these double-length cigarette rods in cigarette rods of simple length, with means for introducing filter plugs double length between the cigarette rods of simple length, with means for Ver¬ binding of the double-length filter plug with the two cigarette rods of simple length by wrapping with a tipping paper, which is separated by means of a cutting device 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 two-web filter tying machine, two material streams 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 patent documents DE-C-38 05 753, DE-C-37 06 753 and DE-C-37 06 751 are known methods and apparatus for producing filter cigarettes from cigarette rods, which are produced in the double-strand process.

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

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

DE-C-37 06 753 shows a method and a device 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, European Patent Applications EP-A-895 724 and EP-A-895 725 each disclose methods for producing filter cigarettes in a filter attachment machine in which double-length cigarette rods are manufactured in double lanes. After cutting the double-length tobacco sticks, the tobacco sticks of simple length are transferred in a staggered arrangement.

In addition, it is known from DE-A-196 26 679 to cut, spread and place a single-length series of double-length tobacco sticks with a double-length filter plug therebetween. 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.

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

This object is achieved by 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 subsequent separation cut through the double-length filter plug filter cigarettes normal utility arise, which is further developed by the fact that two streams of material with cigarette rod filter plug cigarette rod groups are conveyed side by side, wherein the articles .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 flow consisting of a sequence of cigarette rod and filter rod groups arranged one behind the other transversely, wherein the attachment of the covering paper flakes to the articles of the two material flows takes place one after the other and the material flows in the region of attachment of the covering paper flakes side by side 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 tamping devices is achieved becomes. Compared to a one-piece filter attachment machine, the production output on the double-lane filter attachment machine is doubled if two material streams are simultaneously transported at the same conveying speed as in the single-lane filter attachment machine. In addition, it is a simplification that the material flows are guided side by side, whereby it is not necessary to supply the material flows in different ways to the respective pad means. As a result, the structural complexity of a filter attachment machine is reduced, since the two material streams are conveyed on the same conveying means, ie conveying drums. 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 in the grooves of the conveyor drums alternately ^' .

In order to obtain two streams of material, the articles of the material streams are formed from articles of a stream of starting material.

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, after execution of appropriate procedures, cigarette rod filter plug-cigarette rod

Groups formed as intermediates, which are divided in a subsequent step into two material streams.

In particular, the streams of material are separated by spreading the articles of the feedstock 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. In order to ensure secure adherence of the tipping paper sheets 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 paper to be adhered. flake.

According to an advantageous alternative embodiment of the invention, it is proposed that the spacings of the articles of the output current be 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 flow of starting material is divided into two streams of material, the transverse axial distances between the articles of the stream of starting material can be less than the length of the tipping paper leaflets to be adhered, since the attachment of the tipping paper leaflets takes place only after the distribution of the stream of starting material 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 working 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.

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 production of the filter cigarettes from article components of the first partial flow and the first Teil- ström supplied complementary article components filter cigarettes from the article components of the second partial flow and from the second partial flow supplied complementary article components are produced.

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 supplementary components for a filter cigarette, so that the article components and the complementary article components complement one another 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 one conveyor track on a multi-line filter attachment machine, while on another

Conveyor parallel to the production of filter cigarettes on the first conveyor the article components are transported. Following this, the article components with supplementary, d. H. Complementary, associated article components, so that on the second track also filter cigarettes are produced. 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. Thus, in a first process section, a decoupling of a production process from

Filtered cigarettes and a transport process of zugeförderten article components made.

For this purpose, it is advantageous that during the manufacture of the filter cigarettes from articles of the second partial flow and the second

Partial flow supplied complementary article components produced from the articles of the first Teiistroms and the first partial flow supplied complementary article components filter cigarettes, in particular position neutral promoted. 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 organs or Funktionsseinhek th, 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 Filteransetzmaschine allows that at

Failure of a production line in one production section continues to produce cigarettes in the other 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 be placed side by side and / or one below the other. be promoted to each other. 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 design of a filter attachment machine is possible. Due to the common intermediate conveyor device, 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, the Asked 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 of multiple use length are cut into filter cigarettes of simple use length, it being possible within the scope of the invention for the filter cigarettes to be cut immediately after their production or only when the partial flows are merged.

Preferably, tobacco sticks, in particular tobacco rod pairs, are provided and / or supplied as article components of the partial flows and filter plugs, in particular filter plugs double the use length, as well as tipping paper leaflets as complementary article components.

In one alternative, tobacco rod filter plug tobacco rod

Provided and / or supplied to groups as article components of the sub-streams and tipping paper leaflets as complementary article components.

A further solution of the problem with a filter attachment machine is that a covering device is provided in each case for at least two material streams with cigarette rod filter plug cigarette rod groups, wherein the covering devices are arranged one behind the other in the conveying direction of the material streams conveyed side by side.

Preferably, means for parallel guiding of the material flows, in particular in the area of the covering devices, are provided. Such guide means are, for example, double-wide conveyor drums compared to conveyor drums on a single-lane filter attachment machine.

Furthermore, means for forming the streams of material from a stream of starting material are provided, so that double-length tobacco stocks are transferred from a cigarette rod machine to the filter attachment machine. This ensures that, for example, a high-performance cigarette machine with a double-lane Filter attachment can be combined. It is therefore not necessary to precede a double-strand machine of a double-lane filter attachment machine.

A power increase is also achieved if means are provided for shortening the transverse axial distance of the articles of the feedstock stream and / or the streams of material.

In an advantageous development of the invention, means for wrapping the articles of the material streams with the tipping paper leaflets are provided on the filter tying machine.

In the following figures, identical or similar elements or corresponding parts are provided with the same reference numbers, 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 filter attachment machine 10 receives double-length tobacco sticks

15 of 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 conveyance on the conveyor drums 12, 13, the cross-axial distances of the tobacco rods 15 are shortened, wherein in 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 11 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 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 insert drum

FIG. 24 receives dual use length filter plugs 25 from a filter feeder 100 having two staggered filter cartridges 110, 120. 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 assembling the cigarette rod filter plug

Cigarette rod groups on the assembly drum 22, the group items are passed to a spreading drum 23, wherein each second article of the consecutively arranged articles is each assigned 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 piecing machine.

After dividing the starting material stream into two material flows M1, M2, the two material streams M1, M2 are transferred to a conveyor drum 31, wherein on this conveyor drum 31 dje articles of the two streams of material are transported in parallel and side by side. Here are the transverse axial distances between see the articles of each material flow M1, M2 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 papers 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 conveying drum 31, the articles of the two mass flows M1, M2 are indicated on a conveying drum 32, so that tiling 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 attached tipping paper leaflet 55, while the articles of the second mass flow M2 conveyed in parallel 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 on a conveyor drum 36, the two mass flows are 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 double-length filter plug are cut so that filter cigarettes 225 easy 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 material streams M1, M2, two partial streams with article components of filter cigarettes to be produced are provided, the article components cigarette rod filter plug cigarette rod

Groups in the embodiment in Fig. 2 include. A synonymous term for cigarette rod is the term tobacco rod.

The partial streams M1, M2 are each supplied with backing paper leaflets 55, 65 separately and attached as complementary article components. 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.

Zigarettenstab- filter plug-cigarette rod groups, each covering paper leaflets 65 attached as complementary article components of a manufactured filter cigarette double-use length, so that subsequently filter cigarettes are manufactured 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. 2 and FIG. 1, the article components of the two sub-streams on the same conveying devices after provision of the two sub-streams M1, M2 ne- Beneiπander 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.

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 sub-stream M1 (see Fig. 3b) as longitudinally-spaced tobacco rod pairs to a reassembly drum 151. On the reassembly drum 151, double-length filter plugs are inserted between the longitudinally-spaced article components of the sub-stream 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 tipping paper leaflet as a further complementary article component of a pad 50, which are subsequently rolled on the conveyor drum 153 to filter cigarettes double the use length. 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 from the

Cutting drum 154 passed 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 article components of the second partial stream M2 transferred from the intermediate conveyor device 200 from the conveyor belt 140 to the assembly drum 161 are provided with filter plugs of double length and subsequently each provided with a tipping paper leaflet on a conveyor drum 162 by a coating apparatus 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 '.
