An independent claim is also included for a device for connecting smoking article components.

Description

The invention relates to a method and a device for conveying of smoking article groups on a trough conveyor, taking on the smoking article groups each have a compound leaflet with at least a free end is arranged.

The prior art discloses a method of uniting Smoking article components in the form of with a defined pitch supplied on a roller, glued connection laminae and a cigarette mouthpiece group fed on a drum and a facility for uniting Smoking article components in the form of with a defined pitch supplied on a roller glued cords and a cigarette mouthpiece group fed on a drum known. In addition, machines are the Tobacco processing industry, in particular Filteransetzmaschinen known.

Below a defined pitch is in the invention Sense of the given length of the connecting leaflets to understand certain pitch.

A device for connecting cigarette mouthpiece groups by wrapping with glued connection papers, for example by EP-A-0 687 424. Here are the Smoking article components moved through a rolling channel while doing its forward movement around its own axis turned.

Method and device of the type described above are used in particular for confectioning on a filter attachment machine Queraxial promoted filter cigarette. Their performance regarding the article produced and ejected per unit time In the course of time it increased or had to jump the increased efficiency of the upstream cigarette rod machine be adjusted. This achieves the aforementioned Rolling device as a subassembly on a filter attachment machine a critical performance limit, exceeding it inevitably to a reduction in quality or increased tobacco loss, Damage, deformation or even destruction of the manufactured Cigarettes can lead.

The laid-open specification DE-A-25 17 209 discloses a device for combining tipping paper papers and cigarette filter cigarette groups, in the tiling paper on a drum is supplied. When transferring the groups to the tipping paper feed drum, The tipping paper lays on the group around.

Further, European Patent Specification EP-B-0 821 887 a method and apparatus for the association of smoking articles described. According to the technical teaching, the Smoking article components by two consecutive rolling operations connected with each other. Here, the first partial roll In a recording of the drum during and during the transfer of the leaflet to a cigarette mouthpiece group. The final roll is in the form of a multiple rewinding of the partially connected Components executed in a further process step.

The invention is based on the object, a high product quality Rauchartikein, even with higher production of cigarette production to ensure.

In the method of the type mentioned is at the transfer the connecting tab with two free ends on the cigarette mouthpiece group arranged and in a subsequent step by rolling over the components, the connection leaflets around wrapped around the joints of the cigarette mouthpiece group becomes. This is based on the idea that the cigarette mouthpiece group their position on or in the drum should change, in an intermediate step a Teilumschlingung the cigarette mouthpiece group by applying a free end of the leaflet to the cigarette mouthpiece group should be done. In the process, the free length of the connection leaflet becomes shortened, leaving the leaflet end of a subsequent Zlgaretten mouthpiece group is released or not obtained from this becomes. A complete marriage of the Cigarette Mouthpiece Group with the Verbindurigsblättchen then done by Roll over the components, leaving the compound leaflet completely surrounds the butt joints of the Cigarette Mouthpiece Group. By doing that, the connecting leaflet on the cigarette mouthpiece group has a leading end, that after the transfer associated with the cigarette-mouthpiece group can be, the Tallungsabstand between two successive partially connected components are shortened, since the distance gap between the back free end of the connection leaflet and the subsequent cigarette mouthpiece group is enlarged. This gap can then be shortened so that a filter attachment machine with a higher production capacity can be operated.

The leading free end of the connection leaflet can with the cigarette-mouthpiece group glued or partially connected if the compound leaflet is asymmetric on the cigarette mouthpiece group is arranged. Here, the supply takes place of tipping paper with a smooth feed drum.

A Safe Partial Serving Of The Cigarette Mouthpiece Group Will achieved in that after the arrangement of the connecting leaflet on the cigarette mouthpiece group the compound leaflet and the cigarette mouthpiece group by applying a free end of the connection leaflet. This takes place in a process step after the arrangement of the connection leaflet on the cigarette filter group. Preferably becomes the forward in the conveying direction of the cigarette mouthpiece group free end of the connection leaflet to the cigarette mouthpiece group created.

Preferably, the free end of the compound leaflet by means of a contact organ to the cigarette mouthpiece group created.

Moreover, it is advantageous if the pitch of the partially connected Components is reduced. After joining the partially connected components and the Tellumhüllung is the distance between the lolling free end of the connection leaflet and the following, also partially wrapped cigarette mouthpiece group larger than cigarette-mouthpiece groups, where the leaflet at one point according to the state the technique is attached. In shortening the pitch, for example, by moving arms of a drum, may be the funds drum downstream subsidies also be operated with a smaller division, so that Overall, the productivity of a machine with a high Produktqualltät is gestelgert. By the division change or - Reduction can thus more cigarettes per minute in one machine be transported or produced. At the same time the Treated smoking article components gently.

It is particularly advantageous if the pitch of the recordings the hollow drum after the partial connection of the components is reduced. The reduction of the pitch is based on the thought that by applying the anticipatory free End of the connection leaflet to the cigarette mouthpiece group the distance gap between the trailing free end and the following, also teilumhüllten group, enlarged becomes. Due to the larger gap, it is possible to change the pitch on the following facilities or conveyor drums shorten so that a filter attachment machine with a higher throughput of manufactured cigarettes is operated. By shortening the distance of the parts wrapped objects can subsequently the transfer of the tell-connected Smoking article components on a takeover drum with a lesser division.

According to an advantageous embodiment of the method, the partially connected components after the partial connection to a Drum, in particular with a reduced pitch of the drum corresponding division, passed. This can, for example a filter breaker after taking over the components operated from a Strang unit with a smaller pitch become.

To safely assemble the smoking article components is provided that the connecting leaflets and the cigarette mouthpiece groups merged with the same pitch become.

When the pitch between the partially connected components is changed, it is necessary that after delivery of the tell-connected components the pitch of the recordings the trough drum is increased. The adaptation of the reduced Separation distance to the original division guaranteed a reliable operation of the method or a device.

A secure adhesive bond between the smoking article components is ensured by the fact that after the transfer of the connected components to the drum a roll becomes.

In particular, it is advantageous if the Endrollung In the form of a Multiple rewinding of the components is performed.

Furthermore, the actual device of the type mentioned in the introduction is further developed, in that the device for arranging the connection leaflet with two free ends on the cigarette mouthpiece group is trained.

To wrap the Zlgaretten Mouthpiece Group with a partial serving of free leading end to be provided with the connecting leaflets, is a means for partial connection of the components by application a free end of the connecting leaflet, in particular the front in the conveying direction, free end, to the cigarette-mouthpiece group intended. Due to the asymmetrical arrangement of the compound leaflet on the Cigarette Mouthpiece Group becomes the free, anticipatory piece of the leaflet pressed and connected with the cigarette-mouthpiece group. The rear, free part of the compound leaflet forms a Kind of flag.

According to an advantageous development, it is provided that the Means for partial connection of the components between the roller and a transfer drum, based on the conveying direction of the drum, is arranged.

In particular, the means for partial connection as a rotational body and / or attachment member formed.

The free end of the connection leaflet is without wrinkling applied to the cigarette mouthpiece group when the agent for Partial connection at least one application means, preferably one Projection, has.

Preferably, the application means have the same pitch the recordings of the drum of the drum when arranging the connecting sheet on.

It is also advantageous if the recordings of the hollow drum are variable with respect to the pitch. Thereby can the partially connected components to a transfer drum with to be handed over to a smaller division.

Advantageously, at least one roll station for wrapping of the leaflet around the buttocks of the Cigarette Mouthpiece Group intended. The roll station can be replaced by e.g. one Roller block, as shown in DT-PS 16 32 193, or alternatively by a trained by means of bands rolling channel, as in DE-A-198 57 576 shown to be realized.

Further, a machine of the tobacco processing industry, In particular Filteransetzmaschine, with an inventive Device, as described above, formed.

This will result in a targeted and achieved higher throughput and thus production performance of the filter cigarette lines a consistent or u.U. even reduced item usage achieved during the manufacturing process. Furthermore can be a speed reduction and a resulting Reduction of the noise can be achieved, so that in total the efficiency of a filter attachment machine is increased.

In the drawings, the same elements are denoted by the same reference numerals provided, so by a new idea each is disregarded.

In Fig. 1, a device 30 according to the invention with several Drums, as for example in a filter attachment machine is formed, shown schematically in the neck. The Andes Transactions involving means of the device 30 include a in the direction of arrow 1 circulating suction roll 2, on which on the Outside glued connection leaflets 3 with a defined Dividing distance are fed, which is determined by the length of the connecting leaflet 3 is predetermined. The connecting leaflets 3 are placed on holding pieces 28 of the suction roll 2 and become held in the holding pieces 28 by means of suction air openings.

Another participating funding of the device 30 is as a drum 6 formed, which rotates in the direction of arrow 7 and with Drum Holes 8 is equipped on movable dumping arms. A transfer device with movable arms for rod-shaped Article is disclosed, for example, in DE-B-31 37 223.

The drum wells 8 each take a cigarette mouthpiece group 9 on. The cigarette mouthpiece groups 9 are by means of Vacuum, which rests against the suction holes 11, on the conveyor drum 6 held.

The connecting leaflets 3 and the drum troughs 8 at the handover of the connection leaflet 3 to the cigarette mouthpiece groups 9 the same pitch.

When synchronously rotating the suction roller 2 and the drum of the drum 6, the connecting leaflets 3 and the cigarette mouthpiece group 9 moved towards each other and merged. In the Merging a compound leaflet 3 with a cigarette mouthpiece group 9, the connecting leaflet 3 becomes asymmetric with a front free end 4 and a back free End 5 attached to the cigarette mouthpiece group 9. following the attached leaflet 3 with the respective cigarette mouthpiece group 9 of the suction roll. 2 moved away toward a transfer drum 18. The combination from compound leaflets 3 and cigarette mouthpiece group 9 is thereby moved along a leaflet guide 24. The Leaflet guide 24 prevents detachment of leaflet 3 from the group 9.

Below are the cigarette mouthpiece group 9 with the Connecting leaflets 3 along the leaflet guide 24 a Roll star 25 fed to the rotating body on the outside having radially arranged projections 27. The pitch the projections 27 of the rolling star 25 corresponds to the pitch the drum troughs 8 on the suction roll 2 and the Pitch of the holding pieces 28 of the suction roller 2. To a Partial Serving of Cigarette Mouthpiece Group 9 with the Anticipating End 4 of the leaflets 3 run, touched the projection 27, the front end 4 of the connection leaflet third and thus places the front end 4 on the cigarette and mouthpiece group at. The rotational movement of the roller shutter 25 is synchronized with the rotary movement of the drum of the drum 6. The rear, free end 5 of the connecting leaflet 3 changes at the partial wrapping not a relative position to the cigarettes mouthpiece group 9.

After the Teilumhüllung or partial connection of the components 3, 9th the pitch between the drum receivers 8 is shortened, so that the drum receivers 8 in the delivery of teilverbundenen Smoking article components 3, 9 on the roller drum 18 a have shortened (division) distance. After delivery of the partially connected components 3, 9 to the roller drum 18 is the Distance between the drum holders 8 again increased, so that the pitch of the receptacles 8 on the suction roll. 2 again corresponds to the pitch of the connection papers 3.

The roller drum 18 takes over the partially wrapped combination Connecting leaflets 3 and cigarette mouthpiece group 9 in Arrow direction 19 to a (not shown here) roll station on which e.g. between a roller block and the outer circumference of the Rolling drum 18 a rolling channel is formed. The rolling surface of the roller block is considerably longer than the circumferential area of the cigarette and mouthpiece groups 9, so that this rolls over several times and with the Connecting leaflets 3 are connected. Alternatively, the roll instead of the roller block by means of bands, as for example in DE-A-198 57 576.

In Fig. 2, the application of the front free end 4 of the connecting leaflet 3 to the cigarette mouthpiece group 9 means of the roller star 25 shown in detail. The roller star 25 has a projection 27, the synchronous rotation of the rolling star 25 and the drum 6, based on the conveying direction the drum 6 approaches the cigarette mouthpiece group 9, until the projection 27, the front end 4 of the connecting leaflet 3 and to the cigarette mouthpiece group 9 suppressed. The rear free end 5 of the connection leaflet 3, the from a (rear) mandrel 14 of the receptacle 8 rests and of This will remain in its length during this partial connection constant.
