First, based on Fig. 1 explains the production of filter cigarettes on a filter attachment machine.

In Fig. 1 a Filteransetzmaschine F is shown in fragmentary form in a front view, wherein the Filteransetzmaschine F via a drum assembly T for supplying tobacco sticks from a schematically drawn cigarette rod machine P tobacco sticks double the length of use receives.

A cigarette rod machine is known under the name "PRO-TOS" of HAUNI Maschinenbau AG, Hamburg. Under the name "MAX" is a filter attachment machine of HAUNI Maschinenbau AG, Hamburg, known as a machine of the tobacco processing industry.

In the FIG. 1 Filter attachment machine F shown schematically has various functional units: a tobacco rod feed device 211 with a drum arrangement T, a filter feed device 212 with a drum arrangement M, a tipping paper feed device 213, a cigarette manufacturing device 214, a cigarette testing device 215 and a cigarette dispenser 216th

The drum arrangement T of the tobacco rod feed device 211 has a plurality of conveyor drums 118, 119, 120. After transferring the double-length tobacco sticks from the cigarette rod maker P to a transfer drum 118, the double-length tobacco sticks are conveyed cross-axially and transferred to a cutting drum 119, on which the double-length tobacco sticks are cut into single-length tobacco sticks by means of a cutting blade arranged on the cutting drum 119. From the cutting drum 119, the tobacco sticks simple use length are transferred to a spreading drum 120, on which the cut tobacco rod pairs are longitudinally spaced apart or spread apart. Subsequently, the longitudinally axially spaced tobacco rod pairs are transported to the assembly drum 121.

On their way to a collecting drum 121, the tobacco sticks are cut twice the length of use and spread longitudinally axially. On the assembly drum 121 double-length filter plugs are transported via a further drum arrangement M of the filter feed device 212, which are each inserted between two longitudinally spaced tobacco rods. As a result, a sequence of tobacco rod filter plug tobacco rod groups arranged transaxially behind one another is formed on the assembly drum 121.

In order to place double-length filter plugs between the longitudinally spaced tobacco rod pairs on the assembly drum 121, the drum assembly M has a removal drum 114, by means of which filter rods are removed from a filter rod magazine 100, and using cutting blades disposed in the filter drum 114 on the removal drum 114 be cut double length. Subsequently, the filter plugs are transferred to a spreading drum 115 and a subsequent staggering drum 116. The staggered double-length filter plugs are then transferred from the staggering drum 116 to a subsequent loading drum 117 and conveyed transaxially to the compiler drum 121 so that article groups from tobacco rod filter plug tobacco rod groups are formed on the compilation drum 121.

The assembled article groups of tobacco rod filter plug tobacco rod groups are transferred from the assembly drum 121 to a, preferably designed as a tumbling drum, conveyor drum 122. At the same time, tipping papers are supplied synchronously to the assembled tobacco rod filter plug tobacco rod groups by a padding apparatus 110 of the pad paper feeding device. In DE-C-39 18 137 There is described in detail a coating apparatus which is fully incorporated in the content of the present application.

A glued and conveyed tipping paper strip 111 is in this case cut in the tipping apparatus 110 on a cutting drum 112 by the knives of a cutterhead 113 into tipping laminae or connecting laminae. The cut compound leaflets are respectively transferred to the article groups or tobacco rod filter plug tobacco rod groups on the conveyance drum 122.

After adhering the cut and individual bonding sheets to one article group, the article groups are further transported to a subsequent rolling drum 126 and a rolling device 127 by which the bonding sheets are completely wrapped around the tobacco rod filter plug tobacco rod groups be wrapped around. The rolling device 127 consists in one embodiment of a launch bar, a rolling hand with a rolling surface and the output side of a Auskämmwalze, the rolling surface and the roller drum 126 form a rolling channel, are wrapped in the article groups with the connecting papers, with double-length filter cigarettes are formed.

The double-length filter cigarettes are subsequently transferred to a conveyor drum 128 and then to a conveyor drum 129 designed as a cutting drum and provided for further processing on a filter attachment machine. On a cutting drum 129, a cutting blade 132 is arranged, which produces from the double-length filter cigarettes through a central separating cut filter cigarettes simple use length.

The filter cigarettes simple use length are then transferred from the cutting drum 129 to a spreading drum 133. On the spreading drum 133, the filter cigarette pairs are longitudinally spaced apart from each other and then transferred to a first test drum 134. On the test drum 134, a first test element 144 is arranged, which filters the filter cigarettes a first test, for. B. a head end test.

Within the scope of the invention, it is possible for the manufactured filter cigarettes to be subjected to a leak test and / or a head end test and / or a ventilation test on the first test element 144. In addition, it is possible within the scope of the invention that an optical examination of the cigarettes on the drum 134 is carried out by means of the checking device 144.

Subsequently, the cigarettes are transferred from the test drum 134 to a subsequent second test drum 135, at the one second checking device 145 is arranged to subject the cigarettes further quality checks and / or at least one of the aforementioned test not performed on the test drum 134.

From the test drum 135, the filter cigarettes are transferred to a conveyor drum 136. On the conveyor drum 136, a sampling drum 137 is arranged to selectively remove individual samples from the stream of articles of finished filter cigarettes.

From the conveyor drum 136, the two rows formed with transversely axially successively arranged filter cigarettes simple use length to a turning drum 138 with a arranged on the turning drum 138 turning device 139 passed, so that when dispensing the filter cigarettes from the turning drum 138 to a subsequent conveyor drum 140, the filter cigarettes in a Row successively arranged transversely or conveyed. From the conveyor drum 140, the manufactured filter cigarettes are then delivered to a dispensing drum 141, by means of which the filter cigarettes are transferred to a Ablegerband.

In the filter magazine 100, the filter rods required for the filter cigarette manufacture are provided in stock, wherein the filter rods are filled via a laterally arranged on the filter magazine 100, supply means 50 for the filter rods. By means of the feed device 50 filter rods are introduced into the storage space or storage space of the filter magazine 100 under cross-axial promotion in the filter magazine 100 at the feed side of the filter magazine 100 formed with an inlet 101 as a rod-shaped article.

The feeding device 50 has a vertical conveying shaft 52 and a horizontal conveying channel 51 arranged at the end thereof, which opens at the inlet 101 of the filter magazine 100 and via which the rod-shaped filter rods provided by the feeding device 50 are conveyed into the filter magazine 100. For this purpose, the conveyor channel 51 has at least one conveyor belt on its underside, so that the filter rods deposited on the conveyor belt of the conveyor channel 51 are pushed in transaxially conveying the filter rods over the inlet for filling the filter magazine 100.

Moreover, in one embodiment, the conveying drum 128 arranged downstream of the rolling drum 126 can be embodied as a so-called laser drum, wherein perforations are introduced into the covering paper by using corresponding laser devices in the production of filter cigarettes.

The following are the differences in the operation of in Fig. 1 illustrated Filteransetzmaschine for the production of filterless cigarettes explained.

To produce the filterless cigarettes on the filter attachment machine F, the filter rods are first removed from the filter magazine 100 before the filter attachment machine F is put into operation. It is also conceivable that the filter rods remain in the filter magazine 100, but are not removed from the filter magazine. Furthermore, the receiving troughs of the drums of the filter feeder 212 are sealed. That is, in the receiving troughs of the removal drum 114, the spreading drum 115, the staggering drum 116 and the insertion drum 117 corresponding inserts are used. Alternatively, in the formation of multiple vacuum channels for supplying suction air to the conveyor drums the Filteransetzmaschine F a vacuum channel for the drums of the filter feed 212 are closed, so that no vacuum or no vacuum is applied to the receiving troughs of the drums of the filter feeder. The other vacuum channels of a vacuum supply of the filter attachment machine F ensure that a corresponding holding vacuum is provided at the receiving drums on the conveyor drums for conveying the tobacco sticks.

Furthermore, in the production of filterless cigarettes on the filter attachment machine F, the lining supply device 213 is deactivated according to one embodiment, so that, for example, no tipping paper strip 111 is conveyed. In an alternative, the tipping paper strip 111 is e.g. removed by removing the bobbin.

After the takeover of double-length tobacco sticks from the cigarette rod making machine P by the transfer drum 118, the double-length tobacco sticks are conveyed to the cutting drum 119 formed with a cutter so that the double-length tobacco sticks are cut into tobacco sticks of simple length. Subsequently, the tobacco sticks of simple length are conveyed to the conveyor drum 120, wherein the conveyor drum 120 is designed as a spreading drum in the production of filter cigarettes. Using a conveyor drum with adjustable longitudinal axial stroke for the recordings of the conveyor drums, the stroke length of the spreader drum 120 is set to zero in the production of filterless cigarettes, so that the tobacco sticks on the spreader drum are not longitudinally axially spaced during the promotion for the production of non-filter cigarettes. Subsequently, the non-spread tobacco rod pairs are passed to the compilation drum 121, wherein in the production of filterless cigarettes the control flange for the assembly drum 121 is changed or adjusted to shut off the negative pressure in the region between the insertion point for the filter plugs and the transfer point of the tobacco sticks in the production of filter cigarettes at the receiving troughs. The control flange for the assembly drum 121 is preferably constructed so that, corresponding to the production of filter cigarettes, the negative pressure is provided in the region between the insertion point for the filter plugs and the transfer point of the tobacco rods for the receiving troughs of the assembly drum 121. For the production of filterless cigarettes, preferably the drum body of the assembly drum 121 is exchanged, in which case the holding bores at the drum body are at other positions in comparison to the drum body of the assembling drum 121 for the production of filter cigarettes.

Optionally, it is possible in one embodiment that the drum body with the receiving troughs for the assembly drum 121 is replaced using a quick release.

Subsequently, the composite longitudinally spaced apart tobacco rod pairs of composite drum 121 are transferred from the assembly drum 121 to the conveyor drum 120, which subsequently promotes the tobacco rod pairs to the rolling drum (for the produced filter cigarettes).

In the production of filterless cigarettes on the filter attachment F while the rolling device 127 is deactivated, for example by a Wegschwenkbewegung, being exchanged in the promotion of tobacco rod pairs for the production of unfiltered cigarettes during operation change the drum body with the recordings for the tobacco rod pairs to be conveyed on the roller drum 126 becomes. In addition, the control flange for applying the recordings of the drum body is modified or adjusted accordingly with negative pressure. For this purpose, it is possible that a corresponding insert for a control flange is used when exchanging the drum body.

Subsequently, the non-spaced pairs of tobacco rods on the conveyor drum 128 to the second cutting drum 129 (for the production of filter cigarettes) promoted, wherein in the production of filterless cigarettes on the filter tipping the cutting blade 132 (as a cutting device) is pivoted away, so that the cutting drum 129 at the promotion of filterless cigarettes is used only as a (simple) conveyor drum.

According to the invention, in the production of filterless cigarettes on the filter tipping machine F on the first cutting drum 119, the separating cut is carried out by tobacco rods of double length, since the cutting drum 119 has a greater pitch between the receiving troughs than the second cutting drum 129, whereby the mechanical load of the produced filterless cigarettes is lowered. Subsequently, the filterless cigarettes are conveyed via the following conveyor drums of the cigarette testing device 215 and the cigarette dispensing device 216, wherein it is provided that the test caps provided for this purpose are exchanged when testing head ends in the production of filter cigarettes. Otherwise, the drums of cigarette testing device 215 and cigarette dispensing device 216 remain structurally unchanged.

All mentioned features, including those of the drawing alone to be taken as well as individual features, in combination with disclosed other features are considered alone and in combination as essential to the invention. Embodiments of the invention may be accomplished by individual features or a combination of several features.
