CONVEYOR DRUM OF THE TOBACCO PROCESSING INDUSTRY

Description

[0001] The invention relates to a conveyor drum of the tobacco processing industry and a machine of the tobacco processing industry, in particular a drum machine.

[0002] Furthermore, 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 segment groups and / or tobacco sticks and / or filter cigarettes.

[0003] In machines in the tobacco processing industry, especially 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.

[0004] The conveyance of the aforementioned rod-shaped objects during the production of cigarettes, filters, filter cigarettes, or so-called heat-not-burn products or e-cigarettes is generally carried out in modern production machines in the tobacco processing industry using conveyor drums, whose outer surface or drum body is provided with grooves or receiving troughs for the transverse-axial conveyance of rod-shaped objects (cigarettes, filter rods or filter plugs, filter cigarettes). During conveyance, these rod-shaped articles of the tobacco processing industry are generally arranged in rows transversely one behind the other in receiving troughs.

[0005] In filter attachment machines, rod-shaped articles, such as tobacco rods or filter plugs or filter rods, are conveyed transversely axially into receiving troughs on the conveyor drum. The receiving troughs are arranged at predetermined pitches on the peripheral surface of the conveyor drum.

[0006] The pitch distance refers to the axial spacing of the receiving troughs. The distance is measured from the center of the receiving trough to the center of the adjacent receiving trough of the trough conveyor transporting the rod-shaped smoking articles (groups) on the surface, or from the base of the trough to the base of the trough in the case of a prism-shaped receiving trough, for example. The pitch distance in a drum conveyor, also known as a conveyor drum, is the axial spacing or the length of the (circular) arc between (adjacent) trough centers on the circular line on which the trough centers or trough center axes of the troughs are located.

[0007] In addition, WO 2012 / 139720A2 and DE 10 2019 134 097 A1 disclose conveyor drums used in the tobacco processing industry for conveying rod-shaped articles.

[0008] Furthermore, DE 10 2017 127 593 A1 discloses a sliding drum for rod-shaped articles, wherein the sliding drum has transport carriages provided with receiving recesses for the rod-shaped articles. The transport carriages are moved parallel to the rotation axis of the sliding drum.

[0009] Furthermore, DE 28 09 619 A1 discloses a conveyor drum, wherein the conveyor drum comprises movable carriages with receiving troughs. The carriages are moved along the conveyor path in engagement with control cams.

[0010] Furthermore, the embodiment of US 2021 / 0045431 A1 shows in Fig. 4 a sliding drum, wherein the sliding drum has longitudinally movable carriages with receiving recesses for rod-shaped articles.

[0011] An object of the invention is to convey or move rod-shaped articles on a conveyor drum of the tobacco processing industry for rod-shaped articles in a variable manner during their transverse axial conveyance.

[0012] This object is achieved by a conveyor drum of the tobacco processing industry with receiving troughs arranged one behind the other in the circumferential direction, preferably at regular intervals, for rod-shaped articles of the tobacco processing industry, in particular filter rods and / or filter segment groups and / or tobacco sticks and / or filter cigarettes, wherein the conveyor drum has a rotational axis and is driven or can be driven to rotate about the rotational axis, wherein the receiving troughs are each aligned parallel to the rotational axis, wherein at least one, preferably each, receiving trough has a stationary partial trough surface for a rod-shaped article and a movable partial trough surface for the same rod-shaped article, wherein the stationary partial trough surface and the movable partial trough surface of the respective receiving trough extend parallel to the rotational axis of the conveyor drum, which is further developedthat the movable partial trough surface of the respective receiving trough is movable relative to the immovable partial trough surface of the respective receiving trough parallel to the axis of rotation, in particular linearly.

[0013] The invention is based on the idea that, for example, in the production of rod-shaped heat-not-burn products or multi-segment filters, individual rod-shaped article segments are repositioned on the conveyor drum during transverse axial conveying or are aligned by or after a longitudinal axial displacement movement on the conveyor drum. Here, the rod-shaped articles are moved in the longitudinal axial direction by means of the movable partial trough surface of a receiving trough, with the rod-shaped articles being arranged on or in the movable partial trough surface. In particular, the rod-shaped articles are held in the movable partial trough surfaces by means of negative pressure.Through a linear movement of the movable trough surface parallel to the rotational axis of the conveyor drum, the rod-shaped articles are moved in the longitudinal axial direction. At the same time, the rotation of the conveyor drum around its rotational axis conveys the rod-shaped articles transversely axially. During the conveying process of the rod-shaped articles on the conveyor drum, it is possible to relocate or position the rod-shaped articles within the receiving trough between the movable trough surface and the stationary trough surface.

[0014] If, for example, during a conveying process a rod-shaped article is to be displaced or moved in the longitudinal axial conveying direction on the conveyor drum in the receiving trough, it is possible for the rod-shaped article to be displaced from the immovable partial trough surface of the receiving trough into the movable partial trough surface of the receiving trough, for example by applying a negative pressure in the movable partial trough surface, and then the movable partial trough surface together with the rod-shaped article arranged therein or on it is moved or displaced in the longitudinal axial direction, i.e. parallel to the axis of rotation of the conveyor drum, by means of the movable partial trough surface. After reaching a corresponding position or positioning, the rod-shaped article moved in the longitudinal axial direction can then be displaced (back) to the immovable partial trough surface of the receiving trough.This achieves a repositioning of the rod-shaped articles within a receiving trough during the transverse axial conveyance of the rod-shaped articles on the conveyor drum.

[0015] According to the invention, the receiving troughs of the conveyor drum are formed from a stationary partial trough surface and a movable partial trough surface. In particular, the stationary partial trough surface is formed on a rigid drum body. The movable partial trough surfaces are formed, for example, on, at, or in axially displaceable carriages or displacement bodies of the conveyor drum.

[0016] In one embodiment of the conveyor drum, the immovable partial trough surface and the movable partial trough surface of the respective receiving troughs are arranged one behind the other in the circumferential direction of the conveyor drum, and the immovable partial trough surface and the movable partial trough surface of the respective receiving troughs interact with each other in such a way that at least one rod-shaped article is arranged or can be arranged between the movable partial trough surfaces and the immovable partial trough surfaces. This makes it possible for rod-shaped articles to be received in the receiving troughs.

[0017] Furthermore, a design of the conveyor drum is characterized in that the movable partial trough surface of each receiving trough performs a lifting movement between two stroke reversal points during the rotational movement of the conveyor drum about the rotation axis.

[0018] Furthermore, in a further development of the conveyor drum, it is preferred that the immovable partial trough surface and a movable partial trough surface of the respective receiving troughs have at least one or more suction air openings, wherein in particular the suction air openings of the immovable partial trough surface of the respective receiving trough are arranged at, preferably regular, intervals in the longitudinal extent of the immovable partial trough surface and / or the suction air openings of the movable partial trough surface of the respective receiving trough are arranged at, preferably regular, intervals in the longitudinal extent of the movable partial trough surface.

[0019] Negative pressure is applied to the suction air openings, in particular the suction air bores, of the movable partial trough surface and the stationary partial trough surface to hold rod-shaped articles in the partial trough surfaces, thereby securing the rod-shaped articles in the partial trough surfaces on the conveyor drum during transverse axial conveying. A corresponding control element is provided inside the conveyor drum to switch the negative pressure at the suction air openings of the partial trough surfaces.

[0020] According to a further aspect, it is advantageous in the conveyor drum that the movable partial trough surface of a receiving trough is formed on a carriage, wherein the carriage is linearly movable parallel to the axis of rotation of the conveyor drum.

[0021] Furthermore, in one embodiment, the conveyor drum is characterized in that two immovable partial trough surfaces, each of two receiving troughs, are arranged one behind the other and mirror-symmetrically in the circumferential direction of the conveyor drum. For example, the immovable partial trough surfaces are formed correspondingly on the outer side of a rigid drum body.

[0022] In a preferred embodiment, the conveyor drum is provided with two movable partial trough surfaces of two receiving troughs each, one behind the other and mirror-symmetrically on a carriage in the circumferential direction of the conveyor drum, wherein the carriage is linearly movable parallel to the axis of rotation of the conveyor drum.

[0023] Furthermore, it is preferred in the case of the conveyor drum that at least one, in particular motorized, drive, in particular for one or all carriages, is provided for moving the movable partial trough surface of one or more, in particular all, receiving troughs.

[0024] Preferably, the movable partial trough surface of the receiving troughs has a curved, in particular partially cylindrically curved, or rounded or flat support surface for the rod-shaped articles.

[0025] Furthermore, in the case of the conveyor drum, it is preferred that the immovable partial trough surface of the receiving troughs has a curved, in particular partially cylindrically curved, or rounded or flat support surface for the rod-shaped articles.

[0026] In order to cut rod-shaped articles on the conveyor drum during the transverse axial conveying, it is provided according to a preferred embodiment that the conveyor drum has a circumferential groove for introducing a cutting knife in the circumferential direction and / or the receiving troughs with the respective movable partial trough surfaces and the respective immovable partial trough surfaces have a groove for introducing a cutting knife.

[0027] Furthermore, one embodiment of the conveyor drum is characterized by the fact that a cutting blade is arranged on the conveyor drum. In particular, this cutting blade engages the grooves of the movable and immovable partial trough surfaces of the receiving troughs in order to cut the rod-shaped articles arranged in the receiving troughs.

[0028] Furthermore, the object is achieved by a machine for the tobacco processing industry, in particular a drum machine, with at least one conveyor drum described above. To avoid repetition, express reference is made to the above statements, which apply accordingly.

[0029] Furthermore, the object is achieved by a method for the transverse-axial conveying of rod-shaped articles of the tobacco processing industry, in particular filter rods and / or filter segment groups and / or tobacco rods and / or filter cigarettes, on a conveyor drum, as described above. In this regard, express reference is made to the above explanations. The method for the transverse-axial conveying of rod-shaped articles is carried out using a conveyor drum according to the invention.

[0030] According to a preferred embodiment of the method, it is provided that when an article is conveyed by means of the conveyor drum, the article is displaced from the immovable partial trough surface of a receiving trough to the movable partial trough surface of the same receiving trough and / or when an article is conveyed by means of the conveyor drum, the article is displaced from the movable partial trough surface of a receiving trough to the immovable partial trough surface of the same receiving trough. During the method and during the transverse axial conveyance of the rod-shaped articles arranged in the receiving troughs, it is possible to change the position of the rod-shaped articles within the receiving trough.This makes it possible, for example, to displace a stationary rod-shaped article in a stationary partial trough surface after being displaced to the movable partial trough surface by means of the movable partial trough surface by means of a linear movement of the partial trough surface in its longitudinal extent within the receiving trough. In a further embodiment, it is then possible, after a longitudinal axial displacement of the rod-shaped article, to displace it from the movable partial trough surface of the receiving trough into the stationary partial trough surface. This makes it possible for the rod-shaped articles in the receiving troughs to be changed in position during their transverse axial conveyance within the receiving troughs. These position changes can also be carried out multiple times during the transverse axial conveyance on the conveyor drum.

[0031] For this purpose, in one embodiment of the method it is further provided that when conveying an article bar in a receiving trough, in particular during the rotation of the conveyor drum, the article bar is moved by means of the movable partial trough surface of the receiving trough into a cutting position on the conveyor drum by a linear movement of the movable partial trough surface parallel to the axis of rotation of the conveyor drum with the article bar and then the article bar is cut into two article segments by means of a cutting blade engaging in a circumferential groove of the conveyor drum.

[0032] The conveyor drum according to the invention makes it possible to align the article bar with respect to the cutting plane of the cutting blade by means of a corresponding longitudinal axial displacement of the article bar within the receiving trough.

[0033] Furthermore, in one embodiment of the method, it is advantageous that when conveying a plurality of article segments of an article segment group in a receiving trough, in particular during the rotation of the conveyor drum, at least one of the article segments is moved by means of the movable partial trough surface of the receiving trough into a delivery position on the conveyor drum by a linear movement of the movable partial trough surface parallel to the axis of rotation of the conveyor drum with the article segment or with the article segments.

[0034] According to a preferred embodiment, the method further provides that when conveying a plurality of article segments of an article segment group in a receiving trough, in particular during rotation of the conveyor drum, at least one of the article segments of the article segment group is spaced apart in the longitudinal axial direction using the movable partial trough surface of the receiving trough with the at least one article segment of the article segment group arranged therein and using the immovable partial trough surface of the receiving trough with at least one other article segment of the article segment group arranged therein by moving the movable partial trough surface parallel to the axis of rotation of the conveyor drum relative to one another in relation to the at least one article segment of the article segment group arranged in the immovable partial trough surface of the receiving trough.This makes it possible to space apart (initially) non-spaced article segments of an article segment group in a receiving trough on the conveyor drum in the longitudinal axial direction during the rotation of the conveyor drum, by arranging at least one article segment in the immovable partial trough surface of the receiving trough and at least one other article segment of the article segment group is or will be arranged in the movable partial trough surface of the receiving trough and is spaced apart from the rod-shaped article arranged on the immovable partial trough surface by a linear movement of the movable partial trough surface parallel to the axis of rotation of the conveyor drum.

[0035] Furthermore, in one embodiment of the method, it is preferred that an article bar is cut into two article segments in a receiving trough by means of a cutting blade engaging in a circumferential groove of the conveyor drum, and then the two article segments are separated from one another longitudinally axially on the conveyor drum.

[0036] Further features of the invention will become apparent from the description of embodiments of the invention together with the claims and the accompanying drawings. Embodiments of the invention may fulfill individual features or a combination of several features.

[0037] The invention is described below, without limiting the general inventive concept, using exemplary embodiments with reference to the drawings, whereby express reference is made to the drawings for all details of the invention not explained in more detail in the text. They show: Fig. 1 schematically shows a perspective view of a conveyor drum according to an embodiment, Fig. 2 schematically shows a view of the conveyor drum from Fig. 1 in detail, Fig. 3 different cross-sectional views through a divided receiving trough of a conveyor drum according to the invention, Fig. 4 schematically a perspective view of a conveyor drum according to the invention according to a further embodiment, Fig. 5 schematically a perspective view of the conveyor drum from Fig. 4 in a detailed view and Fig. 6 schematically shows a process diagram for the longitudinal axial displacement of rod-shaped articles on a conveyor drum in the cutout.

[0038] Within the scope of the invention, features marked with "in particular" or "preferably" are to be understood as optional features.

[0039] In the drawings, identical or similar elements and / or parts are provided with the same reference numbers, so that a repeated presentation is omitted.

[0040] In Fig. 1 is a schematic diagram of a conveyor drum 10 for the transverse axial conveying of rod-shaped articles 21, 22, 23, which are conveyed in receiving troughs 12 of the conveyor drum 10. The receiving troughs 12 are formed or arranged at regular intervals on the outer side of the conveyor drum 10 in the circumferential direction of the conveyor drum.

[0041] During the transport of the rod-shaped articles 21, 22, 23 on the conveyor drum 10, which has a rotation axis R, the conveyor drum 10 is driven by a drive and rotates about the rotation axis R for the transverse axial conveyance of the rod-shaped articles 21, 22, 23.

[0042] The conveyor drum 10 has a drum body 14 with recesses 18 in which slide bodies 30 are movably arranged. During the rotation of the conveyor drum 10 about the rotation axis R, the rod-shaped articles 21, 22, 23 arranged in the receiving troughs 12 are displaced in the longitudinal axial direction using the slide bodies 30. In the receiving troughs 12 of the conveyor drum 10, the rod-shaped articles 21, 22, 23 are arranged individually, in pairs, or as a segment group with more than two rod-shaped articles.

[0043] In Fig. 2 A schematic view of the conveyor drum 10 is shown in an enlarged view. The receiving troughs 12 of the conveyor drum 10 are each formed by an immovable partial trough surface 16, which is formed on the rigid drum body 14, and a partial trough surface 36 of the carriage body 30. The partial trough surface 16 of the drum body 14 is designed as a immovable partial trough surface for the rod-shaped articles 21, 22, while the partial trough surface 36 is designed as a movable partial trough surface for the rod-shaped articles 21, 22.

[0044] The carriage bodies 30 are displaceable with their partial trough surfaces 36 parallel to the rotation axis R of the conveyor drum. In order to move the carriage bodies 30, a corresponding drive (not shown here) is provided for the carriage bodies 30.

[0045] To accommodate the carriage bodies 30 on or in the drum body 14, the drum body 14 has corresponding recesses 18 in which the carriage bodies 30 can be or are displaced parallel to the rotation axis R.

[0046] As from Fig. 2 As can be seen, the partial trough surfaces 16 of the drum body 14 and the partial trough surfaces 36 of the carriage bodies 30 each form a corresponding receiving trough for the rod-shaped articles 21 and 22, respectively.

[0047] Fig. 3 shows a schematic cross-section through a receiving trough 12 in a not-to-scale or distorted representation. The receiving trough 12 is formed by the partial trough surface 16 of the drum body 14 and the partial trough surface 36 of the carriage body 30. Radial suction air bores 17 and 37, respectively, are provided in the partial trough surfaces 16 and 36, respectively, which can be subjected to negative pressure from a negative pressure source.

[0048] In the left part of Fig. 3 There is no negative pressure at the suction air holes 17 of the drum body 14 and no negative pressure at the suction air hole 37 of the carriage body 30. In the middle illustration in Fig. 3 There is negative pressure at the suction air bore 37, so that the rod-shaped article 21 is arranged on the (movable) partial trough surface 36 of the displaceable or movable carriage body 30, while there is no negative pressure at the suction air bore 17 of the drum body 14. In this case, it is possible that the rod-shaped article 21 resting on or sucked onto the partial trough surface 36 is held by a linear movement of the carriage body 30 perpendicular to the plane of the drawing and is moved together with the carriage body 30 in the longitudinal axial direction.

[0049] After a longitudinal axial movement of the rod-shaped article 21 together with the carriage body 30, the negative pressure at the suction air bore 37 of the carriage body 30 is switched off and at the same time negative pressure is applied to the suction air bore 17 of the drum body 14, so that the rod-shaped article 21 is moved from the partial trough surface 36 of the carriage body 30 in the direction of the partial trough surface 16 of the drum body 14 and is held on the (immovable) partial trough surface 16 by applying a negative pressure to the suction air bore 17.

[0050] If several rod-shaped articles 21 to 23 are arranged in a receiving trough 12, it is possible within the scope of the invention that by applying a negative pressure to suction air holes 17 of the drum body 14, some of the rod-shaped articles are held, while another rod-shaped article of this article group is held by applying a negative pressure to the (movable) partial trough surface 36 of the same receiving trough 12 and is moved longitudinally axially by a linear movement of the carriage body 30, while the other rod-shaped articles which rest against the partial trough surface 16 of the drum body 14 are not moved.

[0051] The carriage bodies 30 are moved linearly and parallel to the rotational axis R of the conveyor drum during the rotation of the conveyor drum 10, in particular between two stroke reversal points. By repeating multiple displacement processes between the partial trough surfaces 16 and 36 and moving the carriage bodies 30 parallel to the rotational axis R of the conveyor drum 10, it is possible to convey the rod-shaped articles 21, 22, 23 on the transversely conveying conveyor drum 10 in the longitudinal axial direction within a receiving trough 12 and to move the rod-shaped articles 21, 22, 23 in the longitudinal axial direction into a predetermined position, in particular a delivery position to a subsequent conveyor drum.In particular, in order to move the rod-shaped articles in the receiving troughs 12, stepwise and, if necessary, multiple longitudinal axial pushing processes are carried out, whereby a repositioning of the rod-shaped articles 21, 22 on the conveyor drum in the receiving troughs 12 takes place.

[0052] When using a conveyor drum 10 according to the invention, which is a component of a drum machine (not shown here) in the tobacco processing industry, it is possible to individually separate the rod-shaped articles 21, 22, 23 of an article segment group, which are arranged next to one another in the longitudinal axial direction in a single receiving trough 12, at a predetermined delivery area to a subsequent conveyor drum, wherein it is provided within the scope of the invention that the rod-shaped articles are sometimes conveyed several times by more than 360° (as a process angle) around the rotation axis R of the conveyor drum. In this case, the rod-shaped articles 21, 22, 23 are successively separated using the carriage bodies 30 and the multiple displacement of the rod-shaped articles 21, 22, 23 between the partial trough surfaces 16 of the drum body 14 and the partial trough surfaces 36 of the transport carriages 30 and moved accordingly to a delivery position.For example, in a three-segment article group, in a first step, an individual segment is delivered to a delivery position after a first rotation. The second article segment of the segment group is delivered after a second rotation, with the second segment being displaced into a delivery position by a longitudinal axial displacement within the receiving trough 12. In a further stepwise pushing process, after a third rotation of the drum, the third article segment is delivered to a subsequent conveyor drum in the delivery position.

[0053] In Fig. 4 A further embodiment of a conveyor drum 10 according to the invention is shown schematically in a perspective view. A cutting blade 20 is arranged on the conveyor drum 10 in order to cut the rod-shaped articles 21, 22, 23 by means of the cutting blade 20.

[0054] For cutting the rod-shaped articles 21, 22, 23, the drum body 14 has a circumferential groove 19 in the region of the cutting blade 20, which is interrupted by the recesses 18. Furthermore, the carriage bodies 30 have circumferential grooves 39 into which the cutting blade engages when the carriage bodies 30 are positioned, so that the positioned and aligned rod-shaped articles 21, 22, 23 are aligned prior to cutting. During cutting, the grooves 19, 39 are aligned with one another in the circumferential direction of the conveyor drum 10. Fig. 5 is a schematic view of the conveyor drum 10 from Fig. 4 shown schematically.

[0055] After the cutting process on the conveyor drum 10, the article segments each formed from a rod-shaped article 21, 22, 23 are spaced apart from one another by retracting the carriage body 30, wherein one article segment remains on the immovable partial trough surface 16, while the other article segment rests on the partial trough surface 36 of the movable carriage body 30 and is spaced apart from the other (non-moving) segment on the partial trough surface 16 by retracting the carriage body 30.

[0056] In Fig. 6 is a schematic section of a process sequence for positioning rod-shaped articles 21, 22, 23 by means of the conveyor drum 10 according to the embodiment in Fig. 1 shown.

[0057] In process step a), the rod-shaped articles 21, 22, 23 are arranged adjacent to the partial trough surface 16 of the drum body 14 by applying a negative pressure to the suction air holes 17. To move the rod-shaped articles 21, 22, 23 to the partial trough surface 36 of the carriage body 30, a negative pressure is applied to the suction air holes 37 of the carriage body 30 and the negative pressure is switched off at the suction air holes 17 of the drum body 14, so that the rod-shaped articles 21, 22, 23 rest against the partial trough surface 36 of the carriage body 30. This is illustrated in process step b).

[0058] Subsequently, in method step c), the carriage body 30 is moved parallel to the rotational axis R of the conveyor drum 10, so that the rod-shaped articles 21, 22 are moved longitudinally axially within the receiving trough 12 together with the carriage body 30. As a result, the rod-shaped articles 21, 22, 23 are moved in the longitudinal axial direction with respect to the relatively stationary drum body 14. Subsequently, in method step d), the longitudinally moved rod-shaped articles 21, 22, 23 are brought into contact with the partial trough surface 16 by applying negative pressure to the suction air holes 17 thereof. In this case, the article segment 23 is arranged in a discharge position on the conveyor drum 10 and is transferred to a subsequent conveyor drum. This is indicated by dashed lines in method step e).

[0059] Simultaneously or subsequently, the carriage body 30 is moved to its starting position as in method step a), with the same movements of the carriage body 30 subsequently being carried out in method steps f), g), h) in a manner analogous to that in method steps b), c), and d), so that in a further step, the rod-shaped article 22 is brought into a delivery position on the conveyor drum 10. The previously described method steps are then repeated to bring the remaining rod-shaped article 21 into the delivery position. List of reference symbols
