Description

The invention relates to a sliding drum in the tobacco processing industry.

The invention also relates to a machine in the tobacco processing industry, in particular a filter manufacturing machine or filter attachment machine, and a filter rod segment supply device for supplying filter rod segments made from filter rods.

In machines in the tobacco processing industry, in particular filter attachment machines or machines for the production of alternative smoking products such as heat-not-burn products or e-cigarettes, conveyor drums are used 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 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.

Also known as conveying drums are shifting drums, e.g. In this case, filter rods of multiple lengths are removed from a filter rod magazine on a filter feed device having a plurality of transport drums and cut into double-length filter plugs on a cutting drum. After cutting, the filter plugs are staggered on a staggered drum, i.e. each cut filter plug is placed separately in a trough of the staggered drum, offset to the next filter plug. Subsequently, in a further process step, the staggered filter plugs are shifted longitudinally and axially on a sliding drum in the receiving recesses, so that the filter plugs are or are aligned one behind the other in a row in the transverse axial direction, whereby the filter plugs arranged and aligned one behind the other in the row are Sliding drum are transferred to a subsequent conveyor drum.

These drums are usually used in the course of the assembly of filter rods and filter cigarettes, with filter rod components of multiple usable lengths being prepared in a so-called transverse process, i.e. transverse to their longitudinal axes, by being subdivided once or several times, staggered and arranged in a row for their subsequent connection with other filter components or smoking article components will.

In EP 1 013 181 A1 discloses a sliding/cutting drum in which the smoking article components or filter pieces are pneumatically displaced in the receiving recesses against stops by applying suction air to suction bores in the receptacles.

In the document GB 2 267 021 A describes a filter attachment machine in which filter rods are removed from two magazines. After removing a first filter rod, this filter rod is cut in the middle and pushed apart transversely axially. A second filter rod from the other magazine is then inserted centrally between the sections of the first filter rod. This filter rod assembly is subsequently cut, staggered and pushed onto drums. This process of "cutting, staggering and moving the filter pieces" is repeated and thus carried out twice in total. The resulting combination filter from the two different filter rods is then transferred to an assembly drum with cigarette rods.

In addition, DE 10 2013 210 634 A1 discloses a sliding drum for a machine in the tobacco processing industry.

One object of the invention is to provide a sliding drum, for example for a filter feed device, in which, among other things, short rod-shaped article segments can be reliably shifted in the longitudinal direction.

This problem is solved by a sliding drum in the tobacco processing industry with a drum body with receiving recesses arranged one behind the other in a row in the circumferential direction of the drum body for rod-shaped articles in the tobacco processing industry, in particular filter rods and/or filter pieces and/or segmented products, with the drum body surrounding a Axis of rotation is rotatable, wherein the receiving troughs each have a trough base, wherein the trough base of the receiving troughs each of a in the conveying direction of the slide is delimited by a trough web leading the drum and by a trough web trailing behind in the conveying direction of the shift drum, with the trough webs extending parallel to the axis of rotation of the shift drum,
at least in one conveying area of the rod-shaped articles on the sliding drum, the receiving troughs are delimited laterally by a stop barrier, which has a stop surface for the rod-shaped articles,
wherein along the trough webs and along the trough base the rod-shaped articles each having a cross-sectional area, in particular a round or circular one, can be displaced or are displaced in the longitudinal axial direction, in particular during the rotation of the sliding drum, in the receiving troughs, preferably in a pneumatic manner, towards the stop barrier,
wherein the receiving troughs each have a trough cross-section delimited by the trough base and the trough webs with a trough cross-sectional area,
wherein the stop surface of the stop barrier faces the articles that can be arranged or are arranged in the receiving recesses, wherein the stop surface of the stop barrier is equal to or larger than the cross-sectional area of the rod-shaped article facing the stop barrier and/or the stop surface of the stop barrier is equal to or larger than that facing the stop barrier Cross-sectional area of the receiving troughs is
and wherein in the region of the stop barrier an air flow channel designed with a curvature is formed in such a way that air that can be conveyed or conveyed from the receiving recesses is or can be guided around the stop barrier.

The invention is based on the idea that for the articles or article segments to be moved or moved in the receiving troughs, a full-surface lateral stop is provided by the stop barrier in the receiving troughs, with the stop surface for the rod-shaped articles in the receiving troughs being equal to or greater than the cross-sectional area of the rod-shaped articles facing the abutment area of the abutment barrier, or the abutment area for the rod-shaped articles is equal to or larger than the trough cross-sectional area of the receiving troughs. This provides a full-surface, continuous stop for the rod-shaped articles to be displaced, which reduces or prevents, for example, the loss of filling material in the rod-shaped articles or article segments when the rod-shaped articles are longitudinally axially displaced in the receiving recesses in cooperation with the air flow channel in the area of the stop barrier . For example, the rod-shaped articles or article segments have reconditioned or reconstituted tobacco material as filling material.

In one embodiment, the stop barrier for the rod-shaped articles to be shifted is arranged in a stationary manner on the shifting drum in relation to the rotatingly driven drum body. In an alternative embodiment, the receiving troughs each have stop barriers which are arranged in the receiving troughs and which also rotate when the drum body rotates.

The lateral displacement movement of the rod-shaped articles in the receiving troughs is limited by the stop barrier, so that after arranging and positioning the rod-shaped articles on the stop surface of the stop barrier, in a further step they are transferred from this position to a subsequent conveyor drum.

In one embodiment of the sliding drum, the stop barrier is arranged between the ends of the receiving troughs. According to another or additional embodiment, the stop barrier is arranged laterally at one end of the receiving recesses.

Due to the fact that a curved air flow channel, in particular a suction air flow channel, is formed in the area of the stop barrier, during the displacement process of the rod-shaped articles in the receiving recesses by applying a negative pressure via the curved air flow channel, the negative pressure at the head end of the rod-shaped article to be displaced, which is the Abutment barrier is facing effective, wherein due to the negative pressure between the head end of the article and the abutment barrier, the rod-shaped article is moved in the direction of the abutment barrier and is positioned at the lateral abutment barrier.

In one embodiment, the air flow channel can branch off from the bottom of the trough in the area of the stop barrier through a recess or the like in the drum body and can be subjected to negative pressure from a negative pressure source. In one embodiment, the air flow channel can also be formed above the stop barrier, e.g. between a cover for the receiving recesses and the stop barrier.

Due to the fact that the stop barrier is designed with a full-surface stop surface, the air flow channel is provided with a curvature in the area of the stop barrier, so that, for example, suction air is routed around the stop barrier. The air flow channel is according to a further aspect as an air flow channel for impact barriers, for example by a recess in the trough base of the receiving troughs or by a half-space in a cover for the receiving troughs above the receiving troughs. In one embodiment, the air flow duct is formed in the bottom of the trough of the receiving troughs, so that the air flow duct is formed as an underflow duct below the stop barrier. According to further, in particular alternative or further, embodiments, the air flow channel is formed above the stop barrier or also laterally in at least one or in both trough webs that delimit the trough base of the receiving troughs.

According to a further aspect of the sliding drum, it is provided that in the conveying area of the rod-shaped articles, an in particular stationary cover for the receiving troughs is arranged on the sliding drum, with the cover in particular extending in the circumferential direction of the sliding drum and being curved in the circumferential direction of the sliding drum. The cover is arranged in particular in the conveying area on the sliding drum, in which the longitudinal axial displacement of the rod-shaped articles in the receiving troughs is carried out. The receiving troughs are preferably designed like a trough, with the trough webs in particular having a (radial) height so that the trough webs protrude beyond the rod-shaped articles arranged in the receiving troughs.

Due to the arrangement of the cover, it is possible that during the conveyance of the rod-shaped articles, such as segments, within the conveying area of the cover, the rod-shaped articles are not or will not be subjected to negative pressure, whereby switching off the holding air or the holding negative pressure in the receiving troughs in the Conveying area of the cover and the rod-shaped articles are moved in the longitudinal-axial direction against the stop barrier by the application of suction air acting along the longitudinal axis to displace the rod-shaped articles in the receiving troughs. As a result, the rod-shaped articles are moved or sucked against the stops by means of the longitudinally axially acting displacement suction air.

In a further development of the sliding drum, it is also provided that the drum body has a groove running in the circumferential direction and having a groove base for receiving the stop barrier, with the radial distance between the groove base of the circumferential groove and the axis of rotation of the sliding drum being smaller than the radial distance between the base of the trough and the receiving troughs to the axis of rotation of the pusher drum. Due to the smaller radial distance of the groove base of the circumferential groove compared to the radial distance of the groove base to the axis of rotation of the sliding drum, it is possible for a stop barrier to be arranged in the groove, with the stop barrier being arranged with a lower edge in the groove, with the lower edge the stop barrier is or is positioned lower than the base of the receiving troughs. In order to form an air flow channel, a depression or the like is formed in the area of the stop barrier below the bottom edge of the stop barrier in the receiving trough or in the drum body in order to form an air flow channel below the underside of the stop barrier.

For this purpose, according to a further development, it is provided that the stop barrier is arranged in the conveying area of the rod-shaped articles in the circumferential groove of the drum body, preferably stationary relative to the rotating or rotatable drum body, wherein in particular the stop barrier having a lower edge is arranged in the circumferential groove in such a way that the bottom edge of the stop barrier is closer to the axis of rotation of the pusher drum than the bottom of the receiving troughs. At least part of the air flow channel is formed below the underside of the impact barrier in the drum body.

Furthermore, in a further development of the sliding drum, provision is made for an air flow channel to be formed in the base of the respective receiving trough in the area of the stop barrier.

Furthermore, one configuration of the sliding drum is characterized in that the cover is mounted on the sliding drum by means of a cover bracket and/or the stop barrier is mounted on the sliding drum by means of a stop barrier bracket, or that the cover and the impact barrier are mounted on the sliding drum by means of a common bracket, or that the Impact barrier is arranged on the cover or that the cover is arranged on the impact barrier.

According to a further aspect and one embodiment, it is advantageous in the sliding drum that each receiving trough has a stop barrier for the rod-shaped articles.

In one embodiment of the sliding drum, it is advantageous for the air flow channel to be formed between the stop barrier of the respective receiving trough and the trough base and/or the leading trough web and/or the trailing trough web of the respective receiving trough. This is according to a further training provided that the air flow channel is formed between the respective stop barrier of the receiving troughs and the cover.

In order to form an air flow channel above the stop barriers arranged in the receiving troughs or above the receiving troughs, a further development of the sliding drum provides that the cover in the region of the stop barriers of the receiving troughs has a radially outward formation or a radially outward bulge.

The object is also achieved by a machine in the tobacco processing industry, in particular a filter manufacturing machine or filter attachment machine, which is designed with a sliding drum as described above.

In addition, the object is achieved by a filter rod segment supply device for supplying filter rod segments made from filter rods, wherein filter rods and/or filter rod segments are conveyed or can be conveyed transversely axially on the filter rod segment supply device, which are designed with a sliding drum according to the invention as described above. To avoid repetition, reference is expressly made to the statements made above.

• 1 a schematic perspective view of a sliding drum according to the invention for conveying rod-shaped articles in the tobacco processing industry,
• 2 shows a schematic, not to scale, cross-section through the sliding drum 1 and
• 3 a schematic top view of a receiving trough of the sliding drum in detail.

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.

1 shows a perspective view of a sliding drum according to the invention. A schematic cross-sectional view through the pusher drum 10, which is not true to scale, is shown in FIG 2 shown. The sliding drum 10 has an outer drum body 12 with receiving troughs 14 which is driven to rotate about an axis of rotation R. The drum body 12 surrounds a control body 11 provided inside the sliding drum 10 for controlling the suction air provided at corresponding bores of the drum body 12, by means of which rod-shaped articles A are held in the receiving troughs 14 or moved longitudinally.

The drum body 12 has receiving troughs 14 in the circumferential direction, in which the rod-shaped articles A are received by a conveyor drum arranged upstream and the rod-shaped articles A are pushed in the receiving troughs 14 in the longitudinal axial direction, i.e. parallel to the axis of rotation R of the sliding drum 10 in the receiving troughs 14.

The sliding drum 10 is part of a drum arrangement, for example a filter preparation device or filter attachment machine or the like. The picked-up rod-shaped articles A, such as filter rod segments or filter rods, are conveyed in the transverse axial direction by means of the sliding drum 10, whereby during the transverse-axial conveyance of the rod-shaped articles A on the sliding drum 10, the rod-shaped articles A in the receiving recesses 14 in the longitudinal axial direction in a conveying area be shifted in the longitudinal direction.

The sliding drum 10 has a cover 16 on its outside in a conveying area in which the rod-shaped articles A are longitudinally axially displaced in the receiving troughs 14 . The cover 16 partially or completely covers the conveying area into which the rod-shaped articles A are displaced longitudinally and axially in the receiving troughs 14 . For example, the cover 16 is made of plastic such as polyethylene (PE) or other flexible or formable material.

In the conveying area in which the recorded rod-shaped articles A in the receiving mul 14, the cover 16 is arranged on the outside of the shift drum 10, the cover 16 being arranged on the outside of the shift drum 10 via a bracket 160. FIG.

As can be seen from the cross-sectional view in 2 shows, the receiving troughs 14 have suction air bores 18 which are subjected to negative pressure in the conveying area into which the rod-shaped articles A arranged in the receiving troughs 14 are displaced longitudinally and axially. In this case, the suction air bores 18 are formed at one end of the receiving troughs 14 .

In 3 a top view of a receiving trough 14 of the sliding drum 10 is shown schematically in detail. The receiving trough 14 has a trough base 141 which is delimited by a leading trough web 142 and a trailing trough web 143 in relation to the conveying direction of the conveyor drum. The suction air hole 18 is formed in the trough base 141 of the respective receiving troughs 14 .

In addition, the trough webs 142, 143 have a circumferential groove 20 in the direction of rotation of the sliding drum 10 or the drum body 12 (cf. 2 ), A stop plate 22 being arranged as a stop barrier for the rod-shaped articles A in the conveying area into which the rod-shaped articles A are displaced longitudinally and axially in the receiving troughs 14 . The rod-shaped articles A to be displaced are accommodated in the receiving depressions 14 on the side of the stop plate 22 which faces away from the other side of the stop plate 22 facing the suction air bores 18 . In other words: the stop plate 22 designed as a stop barrier is arranged between the suction air bores 18 and the rod-shaped articles A (to be displaced).

The circumferential groove 20 here has a groove base whose radial distance from the axis of rotation R of the sliding drum 10 is smaller than the radial distance of the trough base 141 of the receiving troughs 14 to the axis of rotation.

The stop plate 22 is arranged in the groove 20 in the conveying area of the rod-shaped articles A on the sliding drum 10, in which the rod-shaped articles A are pushed longitudinally and axially in the receiving troughs 14, such that the radial distance between the underside of the stop plate 22 and the axis of rotation R is smaller than the radial distance of the trough base 141 of the receiving troughs 14 to the axis of rotation R. In addition, in the area of the stop plate 22 and in the area of the trough base 141 of the receiving troughs 14, an underflow channel 24 is formed below the stop plate 22, so that in the conveying area in which the rod-shaped articles A can be displaced longitudinally axially, the air is drawn through the underflow channel 24 by acting on the suction air bore 18, with the stop plate 22 serving as a stop barrier for the rod-shaped articles A, so that the rod-shaped articles A are moved with one end face in the direction of the stop plate 22.

The stop plate 22 provides a full-surface, lateral stop for the rod-shaped articles A, with the stop surface facing the rod-shaped articles A being larger than the cross-sectional area of the rod-shaped articles A or larger than the cross-sectional area of the receiving troughs 14 between the Trough webs 142, 143 and the trough base 141.

The stop plate 22 is designed in the form of a part circle in the circumferential direction of the sliding drum 10 and is arranged on the sliding drum 10 so that it is held on the holder 160 together with the cover 16 . In one embodiment (not shown here), the stop plate 22 is ring-shaped.

In order to hold the rod-shaped articles A arranged on the stop plate 22 after their longitudinal axial displacement in the receiving recesses 14, holding air bores 26 are provided in the drum body 12, so that the rod-shaped articles A can be held via the holding air bores 26 formed in the drum body 12 by applying negative pressure to the holding air bore 26 held and promoted to a transfer point to a subsequent conveyor drum while rotating the sliding drum 10. The holding air hole 26 is formed in the base 141 of the receiving troughs 14 .

A further lateral stop 122 is arranged at the end of the receiving troughs 14 opposite the suction air bore 14, the lower edge of the stops 122 having a shorter radial distance from the axis of rotation R than the radial distance of the trough base 141 of the receiving troughs 14. For this purpose, in the area of the stop 122 of the receiving recesses 14 an air flow channel 124 is formed so that air can flow through the air flow channel 124 between the drum body 12 and the stop 122. The air flow channel 124 is connected laterally to a ventilation hole 28 . In addition, the air flow channel 124 is connected to a suction air hole 30 .

In the event that the rod-shaped articles A in the receiving troughs 14 in the direction of stop plate 22 are moved, the corresponding suction air bores 18 of the receiving troughs 14 are open by means of the control body 11 arranged inside the drum body 12, so that during the longitudinal axial displacement movements of the rod-shaped articles A in the receiving troughs 14, the suction air bores 18 are subjected to negative pressure, while the suction air bores 30 are closed and the ventilation bores 28 are open, so that air flows (after) via the ventilation bore 28 and the air flow channel 124 into the receiving troughs 14 .

In the event that the rod-shaped articles A are moved to the stop 122, the control body 11 is replaced inside the sliding drum 10, so that the suction air holes 18 are closed and the suction air holes 30 are subjected to negative pressure. Here, the ventilation holes 28 are closed, so that when a negative pressure is applied to the suction air holes 30, the rod-shaped articles A are moved against the respective stops 122. The stops 122 have a stop surface that is larger than the cross-sectional area of the rod-shaped articles A or the cross-sectional area of the receiving troughs 14.

In order to facilitate the longitudinal axial displacement movement of the rod-shaped articles A in the receiving troughs 14, corresponding ventilation holes or the like are provided in a further embodiment in the cover 16.

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.
