Specifically, the illustrated drum assemblies include a first sliding / cutting drum with respect to the conveying direction of the filter rods or filter plugs 20 , a second sliding / cutting drum 30 , one each from two interchangeable relay drums 40 respectively. 40 ' , a sliding drum 50 and an accelerator drum 60 ,

1b and 2 B each schematically show flowcharts in which exemplary method steps of a method according to the invention for producing filter plug 110.1 . 110.2 . 110.3 . 112.1 . 112.2 from filter rods 100 . 100.1 are shown. These process steps simultaneously represent the operation of the exemplary filter feed device, wherein in 1b a flowchart for the operating state 1a and in 2 B a flowchart for the operating state 2a demonstrate.

The flowcharts of 1b and 2 B are subdivided into process sections A-F, wherein in each case a process section essentially a conveyor drum 20 . 30 . 40 respectively. 40 ' . 50 . 60 assigned.

In the in 1a shown operating state are filter rods 100 multi-cuttable, leaving the filter rods 100 three filter plugs each 110.1 . 110.2 . 110.3 a first filter plug length are produced or can be produced. In the in 2a shown operating state are filter rods 100 easy to cut, leaving the filter rods 100 two filter plugs each 112.1 . 112.2 a second filter plug length are produced or can be produced.

Based on 1a and 1b will be described below as three filter plugs according to the invention 110.1 . 110.2 . 110.3 a first filter plug length from a filter plug 100 getting produced.

The filter rods 100 are rod-shaped and have on both sides two faces 102 on. A direction or orientation parallel to the longitudinal extent of the filter rods 100 is referred to in the context of the invention as longitudinal axial, a direction or orientation transverse to it as queraxial.

The filter rods 100 be in a magazine 10 provided for processing and from the first sliding / cutting drum 20 taken from the magazine. This corresponds to the method section A in FIG 1b , Next to a magazine 10 are alternative feeding, by means of which the filter rods are placed on the first sliding / cutting drum, suitable in the context of the invention selectable.

On the first as a removal drum acting sliding / cutting drum 20 are taken from the magazine, uncut filter rods 100 with rotation of the sliding / cutting drum 20 transversely promoted. This corresponds to the method section B in FIG 1b ,

The first sliding / cutting drum 20 has displacement means, not shown, by means of which the filter rods 100 longitudinally axial on the sliding / cutting drum 20 are displaced in the receiving troughs. Depending on the longitudinal axial position in which the uncut filter rods 100 on the first sliding / cutting drum 20 are arranged, the filter rods 100 before cutting them by means of these displacement means to one on the sliding / cutting drum 20 arranged laterally on the receiving trough stop 22 moved longitudinally axially until the filter rods 100 with a face 102 to the stop 22 bump.

In the thus reached longitudinal axial position, the filter rods 100 by means of a on the first sliding / cutting drum 20 arranged cutting device 24 asymmetrically cut. It is from the filter rods 100 one filter plug each 110.1 cut off, leaving a shortened by a filter plug length filter rod 100.1 arises.

The cutting device 24 is designed for example as a rotating cutting blade. Within the scope of the invention are alternative means by which filter rods 100 on the sliding / cutting drum 20 are cutable, suitable selectable.

The lateral stop 22 for the filter rods is adjustable, so that the longitudinal axial distance between the stop 22 and the cutter 24 is changeable or adjustable. This is a simple adjustment of the (Filterstopfen-) length of the cut or cut off filter plug 110.1 allows, without affecting the position of the cutting device 24 must be adjusted in the longitudinal axial direction.

The cutting device 24 (see. 1a ) is in this embodiment, however, in the direction of the arrow shown transversely to the sliding / cutting drum 20 designed to be movable. This will be discussed in more detail below in the description of a change of the filter plug length to be produced.

The shortened filter rods 100.1 and the cut off filter plugs 110.1 be to the subsequent second sliding / cutting drum 30 passed and on this under rotation of the sliding / cutting drum 30 transversely promoted. This corresponds to method section C in FIG 1b ,

The second sliding / cutting drum 30 has shifting means, not shown, by means of which the shortened filter rods 100.1 longitudinally axial on the sliding / cutting drum 30 are displaceable. Depending on the longitudinal axial position in which the shortened filter rods 100.1 on the second sliding / cutting drum 30 are arranged or are the shortened filter rods 100.1 by means of these shifting means up to one at the Sliding / cutting drum 30 arranged stop 32 moved longitudinally axially. This is where the shortened filter rods collide 100.1 with a face 102 to the side stop 32 , The filter plugs 110.1 are not moved, so that the filter plug 110.1 on the sliding / cutting drum 30 in addition to the longitudinal axial shifted filter rods 100.1 be promoted transaxially.

In the longitudinal axial shifted position, the shortened filter rods 100.1 by means of a on the second sliding / cutting drum 30 arranged cutting device 34 symmetrically or centrally cut. Here are the shortened filter rods 100.1 in each case two further filter plugs 110.2 . 110.3 cut.

The second cutting device 34 is designed for example as a rotating cutting blade. Within the scope of the invention are alternative means by which filter rods 100 on the second sliding / cutting drum 30 are cutable, suitable selectable.

The stop 32 is adjustable, so that the longitudinal axial distance between the stop 32 and the cutter 34 and the cutting plane is changeable. This is a simple adjustment of the length of the cut filter plug 110.1 . 110.2 allows without the cutting device 34 must be adjusted in the longitudinal axial direction.

From the multiple filter rods 100 are each three equal length filter plug 110.1 . 110.2 . 110.3 which are subsequently provided for further processing or intermediate storage. In the exemplary drum arrangement shown, the filter plugs are arranged in a row transversely axially behind one another and fed to a production process for filter cigarettes.

For this purpose, the filter plug 110.1 . 110.2 . 110.3 then from the second sliding / cutting drum 30 to a rotating relay drum 40 handed over and under rotation of the relay drum 40 on the relay drum 40 transversely promoted. This corresponds to method section D in 1b ,

On the relay drum 40 are the three filter plugs 110.1 . 110.2 . 110.3 coming from a filter rod 100 were cut, longitudinal axial and transverse axial staggered side by side in each case arranged in a receiving trough, so that in particular a uniform staggering distance or transverse axial distance between the filter plug 110.1 . 110.2 . 110.3 results.

The relay drum 40 is replaceable formed, which is discussed in more detail below in the description of a change of the filter plug length to be produced.

The on the relay drum 40 arranged filter plug 110.1 . 110.2 . 110.3 are subsequently to a sliding drum 50 pass and on the sliding drum 50 with rotation of the sliding drum 50 transversely promoted. This corresponds to method section E in 1b ,

The sliding drum 50 has not shown displacement means for the filter plug 110.1 . 110.2 . 110.3 , By means of which the first staggered mutually offset filter plug 110.1 . 110.2 . 110.3 up to at least one on the sliding drum 50 arranged stop 52 be moved so that the filter plug 110.1 . 110.2 . 110.3 be arranged in a row queraxial axially behind each other. The stop 52 is preferably formed changeable, so that the longitudinal axial position of the successively lined up filter plug 110.1 . 110.2 . 110.3 is suitably adjustable.

From the sliding drum 50 are the cross-axially successively arranged filter plug 110.1 . 110.2 . 110.3 to an accelerator drum 60 passed and under rotation of the accelerator drum 60 on the accelerator drum 60 transversely promoted. This corresponds to method section F in 1b ,

On the accelerator drum 60 becomes the transverse axial distance of the filter plugs 110.1 . 110.2 . 110.3 enlarged and adapted to the subsequent processes. This is achieved for example by the fact that the accelerator drum 60 with a larger circumferential speed than the sliding drum 50 rotates.

The filter plugs are then arranged, for example, on a filter attachment machine M by means of an insertion drum (not shown) between two tobacco rods on a compilation drum (also not shown) for tobacco rod filter plug tobacco rod groups, which are then further processed into filter cigarettes.

The described production of filter plugs according to the invention is characterized in that a simple and quick format change, in particular a simple change of the filter plug length, is made possible.

For example, filter rods 100 used with a different filter rod length, according to the procedure described in each case three filter plugs 110.1 . 110.2 . 110.3 are cut, wherein the filter plug length changes to the same extent as the Filterstablänge. In this type change the filter plug length, the attacks 22 . 32 and or 52 suitably adjusted and adjusted.

A change of the filter plug length to be produced is also achieved if the number of per filter rod 100 produced filter plug 110.1 . 110.2 . 110.3 . 112.1 . 112.2 is changed, for example when the filter rods 100 in each case two filter plugs 112.1 . 112.2 (see. 2 B ) get cut. For this purpose, a further operating state is provided in the context of the invention, in which either the first cutting device 24 or the cutting device 34 not operated.

In the described embodiment of a Filterzuführeinrichtung 1 for which this operating state is in 2a is shown, without limitation of the invention, the first cutter 24 , for example, by a pivoting movement, put out of action. The corresponding flow chart for this operating state is in 2 B shown.

In this operating state ( 2 B ) becomes the first cutter 24 on the first sliding / cutting drum 20 not operated. For this purpose, or is the first cutting device 24 for example, from the first sliding / cutting drum 20 moved away or otherwise put out of action, leaving the magazine 10 removed filter rods 100 on the first sliding / cutting drum 20 be funded uncut or are eligible, as in procedural section B in 2 B is shown schematically.

The following are the filter rods 100 in full length to the second sliding / cutting drum 30 pass and be symmetrical to the cutting device on this 24 aligned and by the second cutter 24 in two equal-length filter plugs 112.1 . 112.2 cut, cf. Procedural section C in 2 B ,

The magazine 10 and the first acting as a conveyor drum or removal drum sliding / cutting drum 20 with their non-operated cutting device 24 as well as the second sliding / cutting drum 30 with the operated cutting device 34 In the present example, they are arranged relative to one another such that in this operating configuration there is no longitudinal axial displacement of the filter rods 100 necessary is. The attacks 22 and 32 are set accordingly.

For the production of two filter plugs 112.1 . 112.2 per filter rod is a staggering drum 40 ' used that against the previously described staggering drum 40 was replaced. This will ensure that the separation distance or the transverse axial distance between the filter plugs 112.1 . 112.2 after the relay drum 40 ' identical to the graduation distance of the filter plugs 110.1 . 110.2 . 110.3 after the relay drum 40 is.

Due to the constant separation distance, which is particularly independent of the manufactured filter plug length, the changes or adjustments of the subsequent conveyor drums and machines are reduced to a minimum. There is only an adaptation to the new filter plug length, for example, the stop 52 on the sliding drum 50 suitably adjusted and adjusted.

All mentioned features, including the drawings alone to be taken as well as individual features that are disclosed in combination with 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.
