Description

The invention relates to a sliding drum of the tobacco-processing industry with receiving troughs for rod-shaped articles of the tobacco-processing industry, in particular filter rods and / or filter pieces and / or segmented products, wherein the sliding drum is arranged that during or when conveying the rod-shaped article in the transverse axial direction, the rod-shaped Article in the receiving wells are axially displaced or moved.

Furthermore, the invention relates to a drum assembly for Queraxialen conveying rod-shaped articles of the tobacco processing industry, in particular filter rods and / or filter pieces and / or segmented products, as well as a machine of the tobacco processing industry, in particular filter attachment machine or filter manufacturing machine.

Moreover, the invention relates to a method for the transverse axial conveying of rod-shaped articles of the tobacco-processing industry, in particular filter rods and / or filter pieces and / or segmented products.

In machines of the tobacco processing industry, in particular filter attachment machines, conveyor drums are used to transport cigarettes, filter pieces or their components. For the purposes of the invention, the term "components" of the cigarettes and filter rods also means sections of paper and the like of flat and / or sheet material, e.g. Sections and / or webs of cigarette paper, filter paper or tipping paper for joining tobacco rods with filter plugs.

The conveyance of the aforementioned objects during the manufacture of cigarettes, filters and filter cigarettes is performed in modern production machines of the tobacco processing industry generally by means of conveyor drums, the lateral surface or the drum body for Queraxialen conveyance of rod-shaped objects (cigarettes, filter rods or filter plugs, filter cigarettes) Grooves or receiving troughs for receiving the rod-shaped objects is provided. The receiving troughs in this case have a trough bottom.

During production, these rod-shaped articles of the tobacco processing industry are arranged in receiving troughs generally in rows transaxially one behind the other.

In addition, as drums drums are known, for example, in filter feeders on Filteransetzmaschinen on which filter plugs are moved longitudinally as rod-shaped article. In this case, multiple filter rods are removed from a filter rod magazine and cut into double-length filter plugs on a cutting drum on a filter feed device having a plurality of transport drums. After cutting, the filter plugs are staggered on a staggering drum, ie each cut filter plug is placed separately in a trough of the staggering drum offset from the next filter plug. Thereafter, the staggered filter plugs are moved in a step on a sliding drum in the receiving cavities longitudinally axially, so that the filter plug then in a Row are aligned in the transverse axial direction one behind the other or are, whereby the successively arranged in the row and aligned filter plug are transferred from the sliding drum to a subsequent conveyor drum.

These drums are commonly used in the assembly of filter rods and filter cigarettes, with multi-use filter rod components in a so-called cross-process, i. transverse to their longitudinal axes, by single or multiple subdivision, staggering and sequential series for their subsequent connection with other filter components or smoking article components are prepared.

In EP-A-1 013 181 discloses a sliding / cutting drum, wherein the smoking article components or filter pieces are moved in the receiving troughs by applying suction air to suction holes of the recordings against longitudinally displaceable stops in a pneumatic manner.

In the document GB-A-2 267 021 is a Filteransetzmaschine described in which two magazines each filter rods are removed. After removing a first filter rod, this filter rod is cut centrally and pushed apart laterally. Subsequently, a second filter rod from the other magazine is inserted centrally between the sections of the first filter rod. This filter rod assembly is subsequently cut, staggered and pushed on drums respectively. This process "cutting, staggering and moving the filter pieces" is repeated and thus carried out a total of twice. The resulting combination filter of the two different filter rods is subsequently transferred to a compilation drum with cigarette rods.

In U.S. Patent 5,984,851 A filter feed in a filter attachment machine will also be described. For this purpose, the filter or filter pieces, which are also referred to as filter plug, several times in succession the drums cut, staggered and moved. By means of the disclosed feeder, the cigarette groups can be delivered with single or dual filters.

Based on this prior art, the object of the invention is to increase in the promotion of rod-shaped articles, for example on a filter feed the process reliability during the cross-axial promotion of filter pieces, the design complexity should be minimized.

This object is achieved by a sliding drum of the tobacco-processing industry with receiving troughs for rod-shaped articles of the tobacco industry, especially filter rods and / or filter pieces and / or segmented products of the tobacco-processing industry, wherein the sliding drum is set up during or during promotion of the rod-shaped Article in the transverse axial direction, the rod-shaped article in the receiving troughs are longitudinally displaceable or displaced, which is further developed in that the sliding drum in the circumferential direction has two juxtaposed rows of transaxially successively arranged receiving troughs, wherein the receiving troughs of a first row of receiving troughs non-aligned to the receiving troughs The second row of receiving troughs are arranged or aligned.

In the drawings, the same or similar elements and / or parts are provided with the same reference numerals, so that apart from a new idea each.

Fig. 1a schematically shows a view of a Filterzuführeinrichtung 10, wherein the filter feeder 10 is integrated, for example, in a schematically designated multi-filter machine M. From a magazine 12 with filter rods 100 filter rods 100 are removed by means of a removal drum 14 and transported to the removal drum 14 cutting blades 16.1, 16.2, 16.3, where the filter rods 100 are cut into several double-length filter plug 111 to 118.

At the in Fig. 1 b In this case, the filter rods 100 are cut into filter plugs 111 to 118 on the removal drum. The filter plugs are also referred to as filter pieces.

The cut filter plugs 111 to 118 are then transferred from the removal drum 14 to a staggering drum 18, on which the filter plugs 111 to 118 are staggered. In staggering, the individual filter plugs 111 to 118 are arranged offset on the staggering drum 18 longitudinally and transversely to each other. From the staggering drum 18, the staggered filter plugs 111 to 118 are then transferred to a first sliding drum 20 so that the filter plugs 111 to 118 are displaced longitudinally outward on the sliding drum 20, wherein on the outside of the sliding drum 20 or at the receiving wells 21, 22 of the sliding drum 20 corresponding position stops (see. Fig. 4a ) are arranged so that after moving the filter plug 111 to 118, the filter plugs 111 to 118 are arranged in the receiving cavities 21, 22 at the position stops.

The sliding drum 20 has two juxtaposed rows R1, R2 with receiving cavities 21, 22. The row R1 with the receiving wells 21 receives the filter plug 111 to 114, while the second row R2 with the receiving wells 22, the filter plug 115 to 118 receives. During the cross-axial promotion of the filter plugs 111 to 118 on the sliding drum 20, the filter plugs 111 to 114 are displaced longitudinally axially outward by the application of suction air, as well as the filter plugs 115 to 118 received in the receiving cavities 22 of the second row R2 also outwardly in the opposite direction postponed. The receiving wells 21 of the first row R1 and the receiving wells 22 of the second row R2 are in this case not aligned with each other in the longitudinal axial direction, so that the receiving wells 21 and 22 are arranged in the circumferential direction entangled to each other (see. Fig. 4a ).

Before the transfer of the filter plugs 111 to 118, the filter plugs 111 to 118 in the longitudinal axial direction at the outer ends of the receiving wells 21, 22 are spaced from each other. Subsequently, the filter plugs 111 to 118 are transferred from the sliding drum 20 to a further, second sliding drum 24 in the receiving cavities 21, 22 of the second sliding drum 24, wherein on the sliding drum 24, the filter plug 111 to 114 and the filter plug 115 to 118 in the longitudinal axial direction in the continuous receiving grooves of the second sliding drum 24 are displaced inwardly against stops 26 and 28. Thereafter, the shifted on the second sliding drum 24 filter plug 111 to 118 are transferred to a further conveyor drum 30 in pairs.

In order to transfer the filter plugs 111 to 114 from the staggering drum 18 into the receiving cavities 21 of the row R1, a combing device 31 is arranged on the sliding drum 20. As a result, the filter rods 111 to 114 are reliably discharged into the receiving cavities 21. For a safe transfer of the filter plug 115 to 118 in the receiving wells 22 of the row R2 of the sliding drum 20 is also a combing device 32 is provided. The combing out device 31 and the combing device 32 arranged next to it differ in their geometrical dimensions, since the transfer points of the filter plugs 111 to 118 are also different in the mutually offset receiving cavities 21 and 22.

In order to ensure a secure transfer of arranged on the outer sides of the receiving wells 21 and 22 filter plugs 111 to 118 to the second sliding drum 24, is between the sliding drums 20, 24 for the disposed in the receiving cavities 21 and längsaxial displaced filter plug 111 to 114 a Auskämmeinrichtung 41st arranged. For the other filter plugs 115 to 118, which are positioned in the receiving cavities 22 of the series R1 on the outside, a Auskämmeinrichtung 42 is provided. When transferring the filter plugs 111 to 118 from the first sliding drum 20 to the second sliding drum 24 in a continuous receiving trough 21, 22 of the sliding drum 24 are each a filter plug from the receiving troughs 21 and a filter plug from the receiving troughs 22 in the same receiving trough 34 of the sliding drum 24 handed over.

In Fig. 2a schematically shows a flowchart for another sliding drum 20 according to another embodiment. In the case of the sliding drum 20, the receiving cavities 21 of the first row R1 and the receiving cavities 22 of the second row R2 are aligned with one another, a gap 50 being formed between the two receiving cavities R1, R2, so that the mutually opposite ends of the cavity webs of the receiving cavities 21 and the receiving wells 22 have a distance.

Above the receiving troughs 21 of the row R1 and above the receiving troughs 22 of the row R2 are in the transfer region of the sliding drum 20 covers 61, 62 are arranged, which are also spaced apart, whereby also a gap 50 between the cover 61 and the cover 62 is.
