Description

The invention relates to a method for producing rod-shaped products in the tobacco processing industry, in particular multi-segment filters, with a predetermined constant product length.

The invention also relates to rod-shaped products in the tobacco processing industry, in particular multi-segment filters, with a predetermined constant product length, and a machine in the tobacco processing industry, in particular multi-segment filter manufacturing machines.

Conveyor drums are used in machines in the tobacco processing industry, in particular filter attachment machines or machines for the production of alternative stick-shaped smoking products such as heat-not-burn products or e-cigarettes, in order to transport cigarettes, filter pieces or their components.

In modern production machines in the tobacco processing industry, the aforementioned rod-shaped objects are generally conveyed during the manufacture of cigarettes, filters and filter cigarettes or so-called heat-not-burn products or e-cigarettes by means of conveying drums whose lateral surface or drum body faces the transverse axis Promotion of rod-shaped objects (cigarettes, filter rods or filter plugs, filter cigarettes) is provided with grooves or receiving troughs for receiving the rod-shaped objects. The receiving troughs for the rod-shaped articles here have a trough base.

During conveyance, these rod-shaped articles of the tobacco processing industry are generally arranged in rows one behind the other in a transverse axial direction in receiving troughs.

Furthermore, in EP 2 862 455 B1 describes a method for conveying rod-shaped articles in the tobacco processing industry, the rod-shaped articles being conveyed transversely axially on a conveyor drum and in a cutting position the rod-shaped articles being cut into a plurality of article rod segments on the conveyor drum by means of at least one cutting device.

One object of the invention is to easily produce multi-segment rod-shaped products, e.g. for further processing, with a product length that is constant, in particular permanently, in a simple manner.

This object is achieved by a method for producing rod-shaped products of the tobacco processing industry, in particular multi-segment filters, with a predetermined constant product length, the rod-shaped products produced being encased in a wrapping material, the rod-shaped products produced each having a group of segments with several, in particular three or more than three rod-shaped segments, each of which has a segment length and which are arranged next to one another and spaced apart from one another in the longitudinal direction of the rod-shaped products, the sum of the individual segment lengths of the rod-shaped segments for each rod-shaped product being less than the predetermined constant product length of the rod-shaped products is
wherein the rod-shaped segments for a rod-shaped product are conveyed transversely axially on conveyor drums and, before being wrapped with a wrapping material, are assembled into a segment group to be wrapped for each rod-shaped product, the segment groups to be wrapped each having a segment group length that corresponds to the predetermined constant product length of the rod-shaped product products corresponds to, have,
wherein before or for the formation of the segment groups for a rod-shaped product in each case the rod-shaped segments are or exist from one another in the longitudinal axial direction, so that an intermediate space is or will be formed in each case between two adjacent rod-shaped segments,
before the segment groups are wrapped with a wrapping material, the two outer rod-shaped segments of a group of segments that have been assembled or are to be assembled are or will be aligned, in particular moved or shifted, in the longitudinal axial direction in such a way that the distance between the outer top ends of the outer segments corresponds to the predetermined constant product length of the rod-shaped products is equivalent to,
and wherein in a subsequent step the assembled segment groups are wrapped by a wrapping material, in particular wrapping strips, in order to provide or produce rod-shaped products with a predetermined constant product length.

The invention is based on the idea that in the case of multi-segment rod-shaped products, in particular with more than three or more segments, the rod-shaped products have a constant product length, with the segments being spaced apart inside the rod-shaped products produced, so that between the respective adjacent segments gaps or gaps are formed inside the rod-shaped products. For example, filter segments or the like are funded as segments, with the provided segment group pen, for example, multi-segment filters can be manufactured with a permanently constant filter length.

The gaps between the segments inside the rod-shaped products are formed in a targeted manner by the method according to the invention, with the outer segments of the respective segment group being aligned with one another before being wrapped with a wrapping material, in particular strips of wrapping material, so that the entire assembled segment group is then wrapped . Before and after the encasing of the segment groups, the aligned distance between the outer head ends of the two outer segments of the segment groups, in particular after their alignment, corresponds to the predetermined constant product length of the rod-shaped products produced. For this purpose, the two outer segments of the segment groups are aligned accordingly or positioned during or during the assembly of the segment groups.

According to the invention, multi-segment rod-shaped products are provided, which each have a predetermined or predetermined constant product length and are further processed on subsequent further processing machines.

For this purpose, a further development of the method provides that when the two outer rod-shaped segments of the assembled segment groups are aligned, the segments arranged between the two outer rod-shaped segments are not moved relative to the outer rod-shaped segments. While the two outer segments of a segment group are moved relative to one another by a longitudinal axial displacement for the alignment, the (inner) segments arranged between them are not moved in the longitudinal axial direction of the segment group during or during the alignment of the two outer segments to one another.

Furthermore, it is advantageous in one embodiment of the method that before the alignment of the two outer rod-shaped segments, the two outer rod-shaped segments are or are positioned relative to one another in such a way that the distance between the outer head ends of the outer segments is greater than the predetermined constant product length of the rod-shaped products . This makes it possible for at least one or both outer segments to be displaced in the longitudinal axial direction in the direction of the adjacent inner segments of the segment groups when the two outer segments are aligned.

In addition, it is preferred in one method step that when aligning the two outer rod-shaped segments, the outer rod-shaped segments are each moved by means of a swash plate. The swash plates are preferably arranged on a conveyor drum and are brought into contact with the outer segments of the segment groups when the segment groups are conveyed with the spaced segments in order to shift them in the longitudinal axial direction in the direction of the adjacent inner segments of the segment groups.

Furthermore, one embodiment of the method is characterized in that, for the compilation of a segment group for a rod-shaped product, a first number of segments, in particular with at least two segments, for the segment group on a first conveyor drum in the longitudinal axial direction in relation to their position in the following assembled segment group are positioned and a second number of segments, in particular with at least two segments, are positioned for the segment group on a second conveyor drum in the longitudinal axial direction in relation to their position in the segment group to be assembled or assembled below. As a result, a first number and a second number of segments are positioned, for example, on different conveyor paths or on different conveyor drums, with the first number of segments and the second number of segments being combined into a segment group in each case in a subsequent method step.

For this purpose it is advantageously provided in a further development that the first number of segments, in particular with at least two segments, for the segment group are arranged between the segments of the second number of segments, in particular with at least two segments, for the segment group.

In addition, in a further development of the method, it is provided that when conveying a assembled group of segments, in particular not spaced apart from one another, for a segment group to be wrapped, a number of, in particular three or more than three, segments or all segments during the transfer are spaced from one another and/or positioned from one conveyor drum to a subsequent conveyor drum in the longitudinal axial direction.

In the context of the invention it is provided that a number of segments, which is smaller than the number of all segments for a segment group, in the longitudinal axial direction from one another when transferring from one conveyor drum to a subsequent one Conveyor drum are spaced apart in the longitudinal axial direction. It is provided within the scope of the invention that during the subsequent transfer between two conveyor drums, the segments that are not yet spaced apart are spaced apart during one of the subsequent transfers, so that when a segment group to be wrapped is provided with spaced-apart segments in the longitudinal axial direction, there are gaps or intermediate spaces are formed between two adjacent segments of a segment group. In an alternative, it can also be provided that all segments for a segment group to be wrapped are simultaneously spaced apart from one another in the longitudinal axial direction during the transfer.

Furthermore, one embodiment of the method is characterized in that when conveying a group of segments, in particular not spaced apart from one another, for a segment group to be wrapped on one, in particular single, conveyor drum, several or all segments are spaced apart from one another in the longitudinal axial direction and/or or be positioned.

In a further development of the method, it is provided that (i) the segments for a segment group are spaced apart and/or positioned in the longitudinal axial direction by means of, in particular stationary, guide bodies arranged on the conveyor drum and/or that (ii) the segments for one segment group by means of sliding bodies for the segments, which can be moved parallel to the axis of rotation of the conveyor drum, are spaced apart from one another and/or positioned in the longitudinal axial direction and/or that (iii) the segments for a segment group are positioned by means of drum rings of the conveyor drum that each execute a stroke path parallel to the axis of rotation of the conveyor drum in longitudinal axial direction spaced apart and / or positioned.

A preferred embodiment of the method is characterized in that the positions of the segments for a segment group to be assembled or assembled are monitored, in particular by means of a camera.

Furthermore, the object is achieved by rod-shaped products of the tobacco processing industry, in particular multi-segment filters, with a predetermined constant product length, the rod-shaped products being encased by a covering material, the rod-shaped products produced each having a segment group with several, in particular three or more than three, rod-shaped segments, which each have a segment length and are arranged next to one another and spaced apart from one another in the longitudinal direction of the rod-shaped products, the sum of the individual segment lengths of the rod-shaped segments for each rod-shaped product being smaller than the predetermined constant product length of the rod-shaped products, the wrapped segment groups each have a segment group length which corresponds to the predetermined constant product length of the rod-shaped products, the rod-shaped products being produced according to the method described above t are

Within the scope of the invention, features that are marked “particularly” or “preferably” are to be understood as optional features.

In the drawings, elements and/or parts that are the same or of the same type are provided with the same reference numbers, so that they are not presented again in each case.

In 1 a drum arrangement T with a conveyor drum 10 is shown schematically, with two positioning drums 11, 12 being arranged on the conveyor drum 10. In the right pane of 1 a process diagram for the promotion of segment groups or of rod-shaped segments 21, 22 is shown schematically in detail.

On the conveyor drum 10, segment groups 20 consisting of segments 21, 22 arranged alternately next to one another are conveyed to the first positioning drum 11, the segments 21, 22 abutting at the top and no gaps between the segments 21, 22 being formed. The segments 21 arranged between the segments 22 are removed from a segment group 20 by the first positioning drum 11 and, after being displaced in the longitudinal axial direction on the first positioning drum 11, are transferred back to the conveyor drum 10, with the segments 21 being placed in the transverse axial direction between the sub-segment group with the segments 22 are arranged so that in the area between the first positioning drum 11 and the second positioning drum 12 groups with the segments 21 and with the segments 22 are arranged alternately in the conveying direction of the conveying drum 10 one behind the other.

The sub-segment groups with the segments 22 are then removed from the conveyor drum 10 by the second positioning drum 12, so that the segments 22 on the positioning drum 12 are spaced apart from one another in the longitudinal axial direction. Subsequently, the longitudinally axially spaced segments 22 are transferred back to the conveyor drum 10, wherein the mutually spaced segments 22 are inserted between the segments 21, which have been longitudinally axially spaced from each other by the first positioning drum 11, so that segment groups 120 with spaced segments 21, 22 are funded. The segment groups 120 with the segments 21, 22 each have a gap 24 between the adjacent segments 21, 22.

By means of the positioning drum 11, 12, the distances between the segments 21, 22 of the segment groups 20 are increased in the longitudinal axial direction between the respective adjacent segments 21, 22. After the segment groups 120 have been formed, the outer segments 22 of the segment groups are aligned with one another (not shown here) on a subsequent conveyor drum using drum discs, so that the distance between the outer head ends of the outer segments 22 corresponds to the product length of stick-shaped products that are to be Longitudinally axial alignment of the outer segments 22 of the segment groups 120 can be produced by subsequent encasing of the segment groups 120 over the entire length to form rod-shaped products with a constant product length.

In 2 Another exemplary embodiment of a drum arrangement T for conveying segments 21, 22 is shown in detail, which is, for example, part of a multi-segment filter manufacturing machine. For example, filter segments or the like are conveyed as segments.

The assembled segment groups 20 with the segments 21 , 22 arranged in alternation are conveyed on the conveying drum 10 to a conveying drum 31 , the segments 21 being transferred from the conveying drum 10 to the conveying drum 31 . The segments 21 are then conveyed by the conveyor drum 31 to a subsequent conveyor drum 32 and transferred to it. On the conveyor drum 32 the segments 21 are spaced apart from one another in the longitudinal axial direction and then transferred to a following conveyor drum 33 .

While the segments 21 are being conveyed by means of the conveyor drums 31, 32, 33, the groups with the segments 22 remaining on the conveyor drum 10 are simultaneously spaced apart from one another longitudinally and axially on the conveyor drum 10 during their transverse axial conveyance between the conveyor drums 31 and 33, so that when they are returned of the spaced segments 21, the segments 21 spaced longitudinally axially are inserted between the segments 22 spaced longitudinally axially by means of the conveyor drum 33, so that segment groups 120 are formed which have spaces 24 between the adjacent segments 21, 22. This is shown in the right process flow diagram.

Subsequently, the outer segments 22 of the segment groups 120 are aligned with one another, so that the distance between the mutually aligned outer head ends of the outer segments 22 of the segment groups 120 corresponds to the product length of the subsequent wrapping of the Seg ment group 120 corresponds to stick-shaped products made with a wrapping strip.

In 3 Another exemplary embodiment of a drum arrangement T, which is part of a multi-segment filter manufacturing machine, is shown in detail.

The drum arrangement T has conveyor drums 41, 42, 43, 44 arranged one behind the other in the conveying direction of the segments 21, 22. Arranged on the conveyor drum 41 is an insertion drum 51 by means of which groups with the segments 22 spaced apart from one another are transferred to the conveyor drum 41 . The groups with the segments 22 are then transferred to the following conveyor drum 42, which then transfers them to the conveyor drum 43.

The arrangement of the group with the segments 22 is shown schematically above the insertion drum 51, the segments 22 of a group being spaced apart from one another in the longitudinal axial direction. In addition, an insertion drum 53 is arranged on the conveyor drum 43, by means of which groups with the segments 21 spaced apart from one another are transferred to the conveyor drum 43. On the conveyor drum 43, the groups with the segments 22 and the groups with the segments 21 are arranged one behind the other in an alternating manner in the transverse axial direction, and are then each transferred to the conveyor drum 44.

While the groups with the segments 21 or with the segments 22 are being conveyed in the direction of a positioning drum 54, which is arranged on the conveying drum 44, the positions of the segments 21, 22 in the respective receiving troughs of the conveying drum 44 are recorded by a camera 60. The segments 21 are then picked up by the positioning drum 54, the segments 21 being spaced apart from one another in the longitudinal axial direction on the positioning drum 54, for example as a function of the position of the segments 21 on the conveyor drum 44 detected by the camera 60. Then the spaced-apart segments 21 is transferred back from the positioning drum 54 to the conveyor drum 44 and inserted between the segments 22 arranged in groups, gaps 24 being formed between the segments 21, 22, so that segment groups 120 are subsequently conveyed on the conveyor drum 44 to a subsequent conveyor drum for further processing. The formation of the segment groups 120 is indicated above the positioning drum 54 in the process flow diagram.

On the subsequent conveyor drums, the outer segments 22 of the segment groups 120 are aligned with one another at a distance between the head ends of the two outer segments 22 which corresponds to the length of the products to be manufactured with a predetermined product length.

In 4 are shown in section cross sections of different conveyor drums 141, 142, 143, on which groups of several segments 21, 22 are promoted. Here, the segments 21, 22 of the segment group 20 are not spaced, so that between the segments 20, 21 no gaps or spaces are formed. Here, the head ends of the opposite head ends of the segments 21, 22 abut one another directly.

With the rotation of the conveyor drum 141, the segment groups 20 are then transferred to a conveyor drum 142, the outer pairs with the segments 21, 22 being spaced longitudinally axially from the middle segment 22 during the transfer from the conveyor drum 141 to the conveyor drum 142. As a result, an intermediate space 24 is formed between the middle segment 22 and the adjacent segments 21 in each case. The longitudinal axial displacement of the two outer segment pairs with the segments 21, 22 is achieved in that the suction bores for the two outer segment pairs with the segments 21, 22 are arranged in such a way that the outer segment pairs move away from the middle segment 22 with a longitudinal axial movement component during the transfer by applying negative pressure to the corresponding outer suction air bores of the conveyor drum 142.

The group with the segments 21 , 22 is then transferred to a subsequent conveyor drum 143 while the conveyor drum 142 rotates. During the transfer from the conveyor drum 142 to the conveyor drum 143, the segments 21, 22 of the outer segment pairs are spaced apart from one another in the longitudinal axial direction, so that a further intermediate space 24 is formed between the outer segments 22 and the adjacent segments 21. During the transfer of the segments 21, 22, the outer segments 22 are subjected to a movement impulse longitudinally and axially by applying negative pressure to the corresponding suction air bores of the conveyor drum 143, so that the outer segments 22 are moved outwards. As a result, a group of segments 120 is formed on the conveyor drum 143, with an intermediate space being formed in each case between the adjacent segments 21, 22. Then the two outer segments 22 are aligned with each other, so that the distance between the outer head ends of the outer segments 22 of the predetermined product length of the products formed from the wrapped group of segments 120.

In 5 a schematic view of a conveyor drum 150 is shown in detail, with segments 21, 22 being conveyed on the conveyor drum 150 in the transverse axial direction. Guide bodies 151, 152 are arranged on the conveyor drum 150 so that the outer segments 21 are moved or displaced outwards in the longitudinal axial direction when they come into contact with the guide bodies 151, 152 in relation to the middle segment 22, creating a gap 24 between the Segments 21, 22 is formed respectively.

Within the scope of the invention, it is possible for the segment groups 20 to have n (n≧3, 4, 5, are.

In 6 various cross-sectional views of a conveyor drum 160 are shown, with the conveyor drum 160 for the individual segments 21, 22 of the segment group 20 having conveyor segments which can be displaced relative to one another along the axis of rotation of the conveyor drum 160, so that one or more segments 21, 22 relative to another segment 21, 22 on the conveyor drum 160 are spaced apart from one another in the longitudinal axial direction.

In the middle representation of 6 is shown that the outer pairs with the segments 21, 22 are each arranged on a conveyor segment of the conveyor drum 160 and are spaced apart from the middle segment 22, so that a gap between the segments 21 and the middle segment 22 is formed. In order to also space the two outer pairs of segments with the segments 21, 22 from one another, the segment pairs are subsequently transferred to a second conveyor drum 161, with conveyor segments of the conveyor drum 161 which can be moved relative to one another being provided for the two outer segments 21, 22 and which are parallel to the axis of rotation of the conveyor drum 161 are displaceable. As a result, an intermediate space 24 is formed between the two outer segments 22 and the adjoining segments 21, so that the segment group 120 formed is then transferred to a subsequent conveyor drum.

In 7 a further embodiment of a conveyor drum 170 is also shown schematically in cross section. In this case, the conveyor drum 170 has drum rings 171, 172, 173, 174, 175, which are preferably designed as elastic drum rings.

In an (upper) recording area, the drum rings 171, 172, 173, 174, 175 with their recordings for the segments 21, 21 of the segment group 20 are arranged side by side in order to record the segment group 20 with the non-spaced segments 21, 22, wherein during the rotation of the conveyor drum 170, the outer ends of the drum rings 171, 172, 173, 174, 175 are spaced apart, so that a space 24 is formed between the segments 21, 22, whereby the segment group 120 with the spaced segments 21, 22 below transferred to another conveyor drum. The outer segments 22 are then aligned with one another on the further conveyor drums, so that after the outer segments 22 have been aligned, the segment group 120 is wrapped by a strip of wrapping material to form a rod-shaped product with a constant product length.

All of the features mentioned, including those that can be taken from the drawings alone and also individual features that are disclosed in combination with other features, are considered essential to the invention alone and in combination. Embodiments according to the invention can be fulfilled by individual features or a combination of several features.
