Description

TECHNICAL FIELD

[0001] The invention relates to a cleaning drum and a method for cleaning rod-shaped articles of the tobacco processing industry. Furthermore, the invention relates to a supply device for supplying article rods. BACKGROUND

[0002] In the tobacco processing industry, a process for the overwrapping of cigarettes or HnB (Heat-not-Burn) articles or multiple filters is known. In the case of the use of special paper, for example hydrophobic paper or paper with a certain paper thickness, or in the case of the use of small paper tubes (Papierröhrchen) in multi-segment articles, a large amount of dust and dirt is produced when machining with a laser unit, in particular perforation for multi-segment articles. This dust and these dirt particles contaminate the machine around the point of origin. Additionally, through the perforation process, dust and dirt are deposited, for example, in the hollow segments, which are difficult to clean, and the dirt can spread in the device during further production processes. By cleaning the product, not only is the quality of the rod-shaped product improved, because there is less or no dirt present in the product or rod-shaped article, but also the dirt in the manufacturing machine is reduced. SUMMARY

[0003] It is the task of the invention to provide a device and a method for improving the perforation process of rod-shaped articles of the tobacco processing industry in order to achieve an improved quality of the rod-shaped articles.

[0004] The task is solved by a cleaning drum for rod-shaped articles of the tobacco processing industry, in particular for cleaning perforated hollow segments of multi-segment articles or rod-shaped articles with perforation openings, having an accommodation for rod-shaped articles, in particular recesses to which a negative pressure can be applied, preferably uniformly spaced apart from one another, particularly preferably having a pitch of at least 4π, 6π, 8π or 10π, preferably the cleaning drum has an outer shell made of metal; a preferably position- fixed compressed air source, which is configured for applying compressed air to the rod-shaped articles, in particular for applying compressed air on the end side; at least one air supply opening, in particular an air supply slit; connection means, in particular a sealing cap, which is arranged at the cleaning drum and is configured for connecting the at least one air supply opening, preferably sequentially, with the rod-shaped articles arranged in the accommodation, in order to supply compressed air streams to the rod-shaped articles on the end side, in order to remove dirt from or out of the rod-shaped articles, in particular to blow dirt out of the perforation openings of the perforated hollow segments of the rod-shaped articles or multi-segment articles, characterized in that the cleaning drum has an extraction device for extracting the blown-off and / or blown-out dirt, in particular of the rod-shaped articles.

[0005] The quality of rod-shaped products is improved by cleaning them, as they contain less dirt. Additionally, contamination of the environment surrounding the piercing equipment and subsequent processing is avoided, as dirt is removed immediately after the piercing process.

[0006] A preferred embodiment of the cleaning roller is characterized in that the extraction device is configured as an extraction shroud arranged on the outside and / or configured as an extraction opening, particularly an extraction channel, leading into the interior of the roller.

[0009] A preferred embodiment of the cleaning roller is characterized in that the cleaning roller has two rows, namely row A and row B, with receiving portions, in particular receiving grooves, arranged side by side for transversely conveying rod-shaped articles in the manner of two side-by-side rows, and preferably the receiving portion of row A is provided with a preferred separate extraction device, and the receiving portion of row B is provided with a preferred separate extraction device.

[0010] A preferred embodiment of the cleaning roller is characterized in that the receiving portion, particularly the receiving groove, has discontinuous portions, preferably two discontinuous portions, so as to hold the longitudinal section of the rod-shaped article, particularly the end section and / or the section with perforated openings, without support.

[0011] A preferred embodiment of the cleaning roller is characterized in that the cleaning roller has an air guiding element for guiding or turning the blown-away and / or blown-out dirt, particularly from rod-shaped articles, to an extraction device, wherein, in particular, the air guiding element is arranged adjacent to an intermittent portion of the receiving portion.

[0012] A preferred embodiment of the cleaning roller is characterized by a positioning device for a particularly movable extraction device (especially an extraction cover), wherein, in particular, the positioning device is configured such that a predetermined, preferably constant, distance is established between the extraction device and the outer surface of the cleaning roller. This positioning device ensures that, for example, after the extraction device has been removed and the extraction device or cleaning roller has been cleaned or maintained, the extraction device is precisely positioned at the cleaning roller, thereby establishing a predetermined, preferably constant, distance between the extraction device and the outer surface of the cleaning roller. For example, this maintains a constant negative pressure effect generated by the extraction device during operation, such as when measuring tensile strength and / or performing other (particularly pneumatic) measurements on rod-shaped articles. For example, the positioning device is configured as a guide or support device for the extraction device. In particular, the extraction device is configured as an extraction cover or the like.

[0013] The task is also addressed by a method for cleaning rod-shaped articles in the tobacco processing industry, particularly for cleaning perforated hollow sections of multi-segment articles or rod-shaped articles, the method comprising the steps of: transversely conveying the rod-shaped article, particularly in a receiving groove where negative pressure can be applied; connecting the end side of the rod-shaped article, particularly (especially by means of a sealing cap), to a source of compressed air to supply a flow of compressed air to the rod-shaped article at the end side, preferably for removing contaminants from or from the rod-shaped article; applying compressed air, preferably having a pressure between 100 mbar and 200 mbar, to the rod-shaped article at the end side; characterized in that, particularly by means of an extraction device, the blown-away and / or blown-out contaminants, particularly those blown out from the perforated openings of the perforated hollow sections of the rod-shaped article or multi-segment article, are extracted.

[0014] A preferred embodiment of the method is characterized in that the extraction is carried out by an extraction shield arranged on the outside and / or by an extraction opening, particularly an extraction channel, constructed into the inside of the roller.

[0015] A preferred embodiment of the method is characterized in that the end portion of the rod-shaped product is connected by moving the sealing cap along its longitudinal axis, such that the sealing cap overlaps the end portion of the rod-shaped product.

[0017] A preferred embodiment of the method is characterized in that the rod-shaped article is held in a receiving groove, particularly a conveying roller or cleaning roller, by means of a holding negative pressure during its transverse transport. In the transport section for the rod-shaped article (where the tensile strength of the rod-shaped article is preferably determined by means of a measuring station M1, and / or preferably the sealing performance by means of a measuring station M2, and / or preferably the ventilation level of the rod-shaped article by means of a measuring station M3), the holding negative pressure for the rod-shaped article is reduced, particularly by at least 25% or at least 50% to 70% or 75%. This allows the effect of the holding negative pressure (applied to the rod-shaped article in the receiving groove during its transverse transport) to be reduced, for example, during the measurement of the tensile strength and / or ventilation level of the rod-shaped article in the transport section, due to the reduction in the holding negative pressure applied in the transport section used for measurement. Outside the transport section where no measurement is performed, the holding negative pressure is increased.

[0018] A preferred embodiment of the method is characterized in that the method is carried out in a dual-track manner, wherein the rod-shaped products are arranged side by side in two rows along the longitudinal axis.

[0019] A preferred embodiment of the method is characterized in that, in particular, the blown-away and / or blown-out dirt of the rod-shaped article is guided or deflected by an air guiding element before being extracted.

[0020] A preferred embodiment of the method is characterized in that the rod-shaped article has a hollow tube section with a wall thickness between 0.2 mm and 1.5 mm, preferably between 0.4 mm and 1 mm, particularly preferably between 0.45 mm and 0.8 mm, especially constructed as a small paper tube, and / or has perforated holes with a width or diameter of at least 0.1 mm, 0.2 mm, or 0.05 mm and / or a maximum of 0.2 mm, 0.3 mm, or 0.5 mm.

[0021] Another task is to prevent or minimize contamination in machines used to manufacture rod-shaped products.

[0022] This task is solved by a supply device for supplying product bars, the supply device having: a storage container for the bar-shaped products, in particular a silo; a cutting roller for cutting the bar-shaped products into product bar segments; and at least one roller arranged behind the cutting roller for conveying the product bar segments; characterized in that: adjacent to the cutting roller and / or adjacent to said at least one roller (in particular the roller directly arranged behind the cutting roller) and / or upstream of the assembly roller (Zusammenstelltrommel) and / or upstream of the joining roller (Tacktrommel), a collection container for collecting the granules and / or product bar segments from the cutting roller or the post-loading roller (in particular the roller directly arranged behind the cutting roller) is arranged.

[0028] Figure 1 A machine 1 is shown for manufacturing rod-shaped products, i.e., manufacturing multi-segment products 530, multi-segment tobacco products 531, or multi-segment intermediate products, for the tobacco processing industry. Machine 1 includes an assembly module 100, a first coating module 200, a second coating module 300, and an inspection and transfer module 400. Machine 1 also includes a control unit 10. The control unit 10 has data connections to the assembly module 100, the first coating module 200, the second coating module 300, and the inspection and transfer module 400.

[0029] Assembly module 100 has supply module A 120 and supply module B 130 for supplying product bar segments 520 or 521. Figure 1 Only two supply modules 120 and 130 are shown in the diagram, but this machine 1 can also have more than two supply modules 120 and 130, such as 2, 3, 4 or more than 4 supply modules.

[0030] The supply module A 120 has a hopper A 121 (preferably a hopper A) and a removal roller A 122 that removes the product bar A 540 from the hopper A 121 and divides it into product bar segments 541 by means of a cutting blade A 123. On a subsequent staggered roller A 124, the product bar segments 541 are staggered and transferred to a transport roller A 125. A subsequently arranged sliding roller A 126 pushes the staggered product bar segments 541 into a single-row arrangement arranged transversely to each other in the axial direction. Further cutting can then be performed on a cutting roller A 127 or on roller 127 using a circular cutter 126M or 127M to form a pair of product bar segments 520. Instead of cutting the product bar 540 into product bar segments 541 by removing the circular cutter 123 from the roller, this can be done by means of a cutting roller 126 or 127 (constructed as a series-sliding-cutting roller, as disclosed in German patent application DE10 2018 113 891 A1). The double-length product bar segments 541 are transferred from roller 126 to roller 127, which can be selectively constructed as a transport roller or a cutting roller, to divide the double-length product bar segments 541 into two single-length product bar segments 520. This cutting of the double-length product bar segments 541 into two single-length product bar segments 520 can also be performed using the circular cutter 128M after transfer to the assembly roller A 128, thereby transferring the double-length product bar segments 541 to the assembly roller. Preferably, a sampling device A 120S for removing samples or an ejection device for ejecting faulty product bar segments 520 or 541 can be arranged on the assembly roller 128. Sensor devices S1 and / or S2 are preferably arranged in the supply module A 120. Sensor devices S1 and / or S2 are configured and set up to measure the performance of product bars or groups of product bars, particularly the number of segments, segment length, product bar length, end faces of product bars, surface surfaces of product bars, and / or diameter. Sensor device S1 is preferably arranged on the transport roller A 125. Sensor device S2 is preferably arranged on the cutting roller A 127.

[0031] From assembly roller A 128, product bar segments 520 arranged side-by-side are transferred to separation roller B 139 to space the two product bar segments 520 apart. On assembly roller B 138, two single-length product bar segments 521 or double-length product bar segments 544 can be inserted into the gaps created between the product bar segments 520. The inserted product bar segments 521 or 544 can be supplied via hopper 131. Supply module B 130 has hopper B 131 (preferably a lifting hopper B) and removal roller B 132, which removes product bars B 543 from hopper B 131 and divides them into product bar segments 544 by means of cutting blade B 133. On subsequent staggered roller B 134, the product bar segments 544 are staggered and transferred to transport roller B 135. The subsequently arranged sliding roller B 136 pushes the staggered product bar segments 544 into a single-row arrangement that is transversely and sequentially arranged to each other in the axial direction. Further cutting can then be performed on the cutting roller B 137 or on the roller 136 using circular cutters 136M or 137M, thereby forming a pair of product bar segments 521. Instead of cutting the product bar 543 into product bar segments 544 by removing the circular cutters 133 from the roller, this can be done by means of the cutting rollers 136 or 137 (constructed as tandem-sliding-cutting rollers, as disclosed in German patent application DE 10 2018 113891 A1). The double-length product bar segments 544 are transferred from the roller 136 to the roller 137, which can be selectively constructed as a transport roller or a cutting roller, to divide the double-length product bar segments 544 into two single-length product bar segments 521. This cutting of the double-length product bar segment 544 into two single-length product bar segments 521 can also be performed using a circular cutter 138M after the product bar segment 544 has been transferred to the assembly roller B 138, thereby transferring the double-length product bar segment 544 to the assembly roller. A sampling device B 130S for removing samples or an ejection device for ejecting faulty product bar segments 521 or 544 is preferably arranged on the assembly roller 138. Sensor devices S3 and / or S4 are preferably arranged in the supply module B 130. Sensor devices S3 and / or S4 are configured and set up for measuring the performance of the product bar segment or the group of segments composed of product bars, particularly the number of segments, segment length, product bar segment length, end face of the product bar segment, surface of the product bar segment, and / or diameter. Sensor device S3 is preferably arranged on the transport roller B 135. Sensor device S3 is preferably arranged on the cutting roller B 137.

[0032] A swaying device can be arranged on rollers 138, 139 and / or 128 to sway, align, or generate segments 501, 502, wherein segments 520, 521 are in contact at their ends. End-side contact of the segments may be disadvantageous in the manufacturing process because the end faces of the segments are subjected to stress, which may, for example, cause damage, visual abnormalities, or particles (such as tobacco debris) and detachment.

[0033] The product rod segments, preferably four product rod segments (520, 521), are transferred from the assembly roller B 138 to the first covering module 200, preferably to the reversing unfolding roller (Wende-Spreiztrommel) 299. The reversing unfolding roller is preferably constructed according to the embodiment disclosed in German patent application DE 10 2020111 946 A1. The segment groups 502 are thus reversed and spaced apart by the reversing unfolding roller, such that at least two outer product rod segments at the ends of segment group 502 and at least two outer product rod segments at the other ends of segment group 502 are centered in the segment group and face each other after the reversal. After the reversal, a gap exists in the middle of the segment group for inserting additional product rod segments of single or double the usable length. Preferably, the reversal and the spacing or gap-creating steps are performed simultaneously in one method step.

[0034] The arrangement structure 600 for coating the rod-shaped articles can be an integral part or only part of the first coating module 200 and / or the second coating module 300. The arrangement structure 600 for coating the rod-shaped articles can be an integral part or only part of the machine 1, particularly from the assembly module 100, supply modules 120, 130, coating modules 200, 300 and inspection and transfer module 400.

[0035] In the first coating module 200, additional product bar segments are preferably provided and conveyed to the assembly roller 298 via a transport path. The resulting segment group 503 is then transferred to the conveying device S 240 (a component of the joining device 280). The supply module of the first coating module 200 has a hopper 291, a removal roller (on which product bars 546 are cut into product bar segments 547, wherein the removal roller 292 is partially engaged with one or more cutting blades), a staggered roller 294, a transport roller 295, a sliding roller 296, and a transport roller 297. In other designs of the supply module, the staggered roller 294 can be configured as a transport roller and cut product bars 546 into product bar segments on a series of sliding-cutting-staggered rollers 296. Preferably, the supply module of the first coating module 200 has a cutting device (i.e., the removal roller 292) and cutting blades 293 and / or a cutting device (i.e., a series of sliding-cutting-staggered rollers 296).

[0036] The first covering module 200 has a first material supply device 210, which provides a material width 211, preferably a first material width 211. Figure 7 The diagram shows a material width providing device 310 for the second covering module 300. All illustrated and described embodiments of the material width providing device 310 are feasible embodiments of the material width providing device 210 for the first covering module 200.

[0037] The material web providing device 310 has an unwinding device for unwinding a material web 311 wound on a spool, which is preferably guided by one or more steering pins and / or steering rollers and can be conveyed along a conveying path FM1FM321. A first traction roller pair 301 conveys the material web 311 along the conveying path FM1FM321. A first restoring force reducing unit 302 is arranged after the first traction roller pair 301, which is preferably configured as a crusher. The restoring force reducing unit 302 is configured to reduce the bending stress of the material web 311 and preferably the material web segment 321 cut from the material web 311, thereby reducing the restoring force of the material web 311 or the material web segment 321 after the overcoating process. The material web providing device 310 has surface processing units 307, 307L, and 307C, which are preferably configured as second return force reducing units to process the surface of the material web 311, especially when using thicker, hydrophobic, or coated material webs 311. This is possible to reduce the return force of the material web 311, thus processing or roughening the surface to allow for the advantageous application of adhesives or bonding agents, or to provide the material web 311 with a structure, particularly a curled structure or an embossed structure. A pair of traction rollers 303 is arranged after the surface processing units 307, 307C, and 307L for conveying and / or guiding the material web. In addition to surface processing units 307, 307C, and 307L, or in the absence of surface processing units 307, 307C, and 307L, surface processing units 313 and / or 314 may exist. These surface processing units are preferably configured as second reset force reducing units, and are preferably configured as brush units or plasma processing units. Surface processing units 307, 307L, 307C, 313, and 314 are preferably configured for processing the surface of the material web 311 on one side, or for processing the surface of the material web 311 on both sides, preferably simultaneously. The material web providing device 310 has a first adhesive applicator 305 for applying adhesive and / or bonding agent K1 to the surface of the material web 311, particularly for applying cold adhesive. The first adhesive applicator 305 has a reservoir 306, which supplies, for example, adhesive and / or bonding agent K2 to the application roller or nozzle. The preferred material width supply device 310 has a second adhesive applicator 308 for applying glue and / or adhesive to the surface of the material width 311, particularly for applying hot glue. Particularly advantageously, the material width supply device 310 has first and second adhesive applicators 305 and 308 for applying hot and cold glue, so as to use fast-bonding adhesives or hot glues as well as slow-bonding adhesives or cold glues. This enables a particularly advantageous initial bond between the material width segment 321 and the segment group 504, and a particularly advantageous long-term bond between the material width segment 321 and the segment group 504.The preferred material web supply equipment has an activation device and / or curing device 309 preferably arranged adjacent to the material web 311. When using special adhesives and / or glues, the adhesives and / or glues can be activated to impart particularly advantageous adhesion properties before joining the material web segments 321 to the segment group 504. This can be done, for example, by a heating device and / or by an ultraviolet irradiation unit and / or by a spraying unit of an additional bonding component for spraying two-component adhesives.

[0038] Surface finishing units 307, 313, and 314 are preferably configured as roller-based surface finishing units, for example, as curling units 307C, 313, and 314. Curling units 307C, 313, and 314 have curling rollers 307C-1 and 307C-2 and preferably have mating rollers, wherein... Figure 10 and Figure 11 A feasible design scheme is shown. The mating roller is preferably constructed as a smooth roller, so that the material web 311 has curling on only one side. Figure 9 The diagram shows a longitudinal cross-sectional view of the material web 311 along the longitudinal axis LA. The material web 311 has a thickness D. A deepening 312 is created in the material web 311 by the action of a winding roller and a mating roller. Preferably, the deepenings are arranged at regular intervals and preferably perpendicular to the longitudinal axis. The deepenings 312 can be arranged obliquely to the longitudinal axis of the material web 311 and / or extend over the entire width of the material web 311. In other designs, the extension of the deepenings does not exceed the entire width, i.e., having an edge region greater than 1 mm, 2 mm, or 3 mm, or between 0.5 mm and 4 mm, preferably between 1.5 mm and 3 mm, or i.e., having an edge region greater than 10%, 20%, or 30% of the width of the material web 311. Figure 12 An exemplary embodiment is illustrated herein. An exemplary crimping unit for generating a crimp curve transverse to the transport direction of the material web is, for example, described in U.S. Patent 3,849,526. Figure 2 , Figure 3 and Figure 6 As shown in the figure, it has Figures 10 to 12 The exemplary pattern shown is illustrated. If the rolled material web 311 produced by the roller-based surface processing unit 307C is cut into material web segments 321 and adhered or joined to the segment group 504, the restoring force is reduced by introducing the roll curve. Figure 8a A group of segments 504 with pre-treated material width sections 321 is shown. The curl curves are preferably adapted to the diameter of the group of segments 504 such that the curl curves are not adversely affected when the end sections of the material width sections 321 overlap, especially when the curl curves are arranged vertically to each other (in...). Figure 8b(Exemplary illustration). Here, a non-equidistant arrangement of the curled curves is possible on the material section 321.

[0039] The material web 311 can preferably be processed by surface processing units 313, 314, and 307 configured as brush units. Here, the surface of the material web 311 is roughened to improve adhesion to glue or adhesive. A brush is arranged adjacent to the material web 311, which rotates against or along the conveying direction.

[0040] The material sheet 311 can preferably be processed by laser-based surface processing units 313, 314, and 307L. Here, the surface of the material sheet 311 is processed by the laser unit, for example, by providing a deepening portion, in order to reduce the restoring force of the material sheet segments 321 of the covered segment group 504. For example, it can produce... Figure 9 The material width of the processed groove is shown. The laser-based surface processing units 313, 314, and 307L are preferably constructed according to the laser cutting units from DE 10 2019 006 932, DE 20 2020 000353 U1, DE 20 2021 002 279 U1, or DE 102017 216 133, wherein the laser intensity must be adapted accordingly.

[0041] Surface processing units 307, 313, and 314 are preferably configured as plasma processing units. The plasma processing units are configured to generate atmospheric pressure plasma, gas plasma, or low-pressure plasma. The plasma processing units are configured to perform plasma processing comprehensively, partially, or selectively. Preferably, the plasma processing units clean or coat the surface of material section 311.

[0043] Material width providing unit 310 conveys material width 311, especially processed material width 311, to joining device 380 or conveying device P 330. The described embodiment of material width providing unit 310 is also a possible embodiment of material width providing device 210. Material width providing unit 210 conveys material width 211, especially processed material width 211, to joining device 280 or conveying device P 230. The reference numerals for material width providing devices 210 and 310 are similar and not all are explicitly illustrated in the drawings.

[0044] The first coating module 200 includes a conveying device P 230 and a cutting device 220. The conveying device is configured as a suction roller 230, preferably a slotted suction roller 230, and the cutting device is preferably configured as a rotating cutter roller. The cutting device 220 and the conveying device P 230 are preferably as described in German patent application number 10 2024 101 973.5. Figures 2 to 4 The structure is as shown and described in the accompanying text paragraphs. The relevant text paragraphs are particularly the paragraphs from page 15, line 21 to page 20, line 18. The material width 211 extends on the suction roller 230 and is cut into material width segments 221 by means of the cutting device 220, especially the cutter roller. The conveying device P 230, especially the suction roller, conveys the material width segments 221 from the receiving portion, especially the groove, to the transfer or pressing portion, where the material width segments 221 on the conveying device P 220 are moved, joined, or adhered to the segment group 503 composed of the product rod segments 520, 521, 522D (in... Figure 2(Illustrated by reference numerals in the accompanying drawings of the second covering module 300). The pressing gap dimension 245 is minimal at the transfer or pressing location. The pressing gap dimension 245 is preferably the minimum distance between the receiving bottom of the receiving portion 232 (especially the groove) of the conveying device P 230 and the receiving bottom of the receiving portion 242 (especially the groove) of the conveying device S240. When the material web section 221 is arranged in the receiving portion 232 of the conveying device P 230, the material web section 221 is preferably pressed and / or pulled into the receiving portion (especially the groove) of the conveying device P 230 by means of a device 246 for pulling and / or pressing. Preferably, the material web section 221 is pressed and / or pulled such that it is arranged on the receiving bottom of the receiving portion 232. The device 246 can be configured as a rotating device having punches arranged radially in the circumferential direction to press the material web section 221 into the receiving portion of the conveying device P230. Device 246 can be configured as a swivel device with one or more removable punches to press the material section 221 into the receiving portion of the conveying device P 230. Device 246 can be configured as a suction device to draw the material section 221 into the receiving portion of the conveying device P 230. Preferably, the receiving portion 232 is configured with an opening, particularly a suction opening, which is connected to a negative pressure source via a conduit. Such device 246 in Figure 2 As shown, however, they are clearly labeled with reference numerals from the second covering module 300. Figure 2 The design shown is also a feasible implementation that can be arranged in the first covering module 200. Device 246 or 346 in Figure 1 It is not explicitly stated in the text, but in particular by following the... Figure 2 The implementation method is in Figure 1 This is a preferred embodiment, where the module is integrated into the first covering module 200 and / or the second covering module 300. Figure 2 While it is not explicitly shown that the material section 221 is pressed and / or pulled onto the receiving bottom of the receiving portion 232, this should also be considered as disclosure. Preferably, the material section 221 is pressed onto the receiving bottom by the section assembly 503.

[0045] Figure 2 The embodiments shown are preferred embodiments of the first and / or second covering modules 200, 300 with corresponding reference numerals (e.g., 221, 230, 240, 246, 245, 241, 242, 2411, 2411, 243, 503) or, for example, with similar reference numerals for the second covering module 300 (i.e., 321, 330, 340, 346, 345, 341, 342, 3411, 3411, 343, 504).

[0046] Figure 2The diagram illustrates conveying devices P 330 and S 340, as well as a device 346 for drawing and / or pressing material web segments 321 into a receiving portion 332 of the conveying device P 330. The conveying device P 330 rotates clockwise and conveys the material web segments 321 to a transfer or pressing location. The conveying device S 340 rotates counterclockwise and conveys segment groups 504 to the transfer or pressing location. The conveying device S 340 has a protrusion 341 with a receiving portion 342, particularly a groove, in which it receives and / or holds article bar segments 520, 521, 522, 523D and / or segment groups 504. At the transfer or pressing location, the material web segments 321, preferably glued paper strips, are adhered to the segment groups 504, forming joined segment groups 504T. The segment group 504 and the material web section 321 are connected to each other via a planar contact area 504K through the receiving part 332, particularly the groove, of the conveying device P 330. The segment group 504 has an annular, preferably circular, cross-section, wherein the planar contact area 504K of the segment group 504 is formed by an angle range of 5° to 170°, preferably 10° to 130°, 20° to 100°, or 45° to 75° about the cross-section of the segment group 504, and / or wherein the planar contact area 504K of the segment group 504 has an extension along the circumference of the cross-section of the segment group 504 or along the transport direction of the conveying device S 340, the extension being greater than 1.5 mm, 2 mm, 2.5 mm, or greater than 3 mm, or between 1 mm and 4 mm, preferably between 1.5 mm and 3.5 mm.

[0047] To achieve a reliable and particularly advantageous connection and / or a particularly advantageous joint or adhesion, a pressing gap size 345 is provided, which is smaller than the diameter of the product bar segments 520, 521, 522, 523 and / or the segment group 504. This allows for a joining process with advantageous pressure, thereby connecting the material web segment 321, preferably the glued paper strip, to the segments, even in the case of particularly thick, rough, smooth, coated, and / or hydrophobic material web segments 321. The pressing gap size 345 at the segment group 504 for pressing the material web segment 321 between the conveyor P 330 and the conveyor S 340 (especially between the receiving bottom of the receiving part of the conveyor P 330 and the receiving bottom of the conveyor S 340) is between 7 mm and 7.8 mm, preferably between 7.3 mm and 7.7 mm, or particularly less than 7.6 mm, preferably less than 7.7 mm, and especially preferably less than 7.5 mm. The diameter of the product bar segments 520, 521, 522, 523 and / or the segment group 504 is, for example, 7.9 mm. The material web segments 321 are advantageously attached to the segment group 504 by an overpressure of a fraction of a millimeter, so that the conveying device S 340 can continue to convey the joined segment group 504T without the material web segments 321 shifting, detaching, and / or experiencing further misalignment. The overpressure is advantageously achieved by a pressing gap size that is 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, 1.2 mm, 1.4 mm, 1.5 mm, or at least 1.5 mm smaller than the diameter of the segment group 504.

[0048] A compression device 348 and / or a pre-folded star-shaped member 348 may preferably be arranged adjacent to the conveying device S 340 and behind the conveying device P 330 along the conveying direction. The pressing gap size between the compression device and the conveying device S 340 can be constructed similar to the pressing gap size 345 described above, so as to allow over-pressure during the engagement process and / or when the compression device 348 and the receiving part of the conveying device S 340 work together.

[0049] The conveying device S 340 has protrusions 341 with receiving portions 342 arranged radially on the outside. These protrusions have a front side boundary 3411 and a rear side boundary 3412. Because a planar contact area is generated during the overpressure and / or joining process, a portion of the material width section 321 of the joined segment group 504T bends and requires free space so that this portion of the material width section 321 does not contact the peripheral side surface of the conveying device S 340 and become contaminated. For this reason, the protrusions have a height to create free space for the portion of the material width section 321. The radially constructed outer protrusions 341 (on which the receiving portions 342 for the segment group 504 are arranged) have a height of at least 5 mm, 6 mm, 8 mm, or 5 mm to 50 mm, preferably 10 mm to 25 mm. The height of the protrusions 341 is adapted to the diameter of the article bar segments and the segment group 504. A spacing retainer 343 is preferably arranged at the rearward side boundary of the protrusion 341. This spacing retainer prevents adhesion of material web section 321, especially glued paper strips, and reduces contamination. The spacing retainer 343 is preferably constructed as radially outwardly extending grooves or ribs, arranged side by side with each other along the rotation axis of the conveying device S 340. Preferably, 5, 10, 12, 15, 20, or 25 grooves or ribs are arranged along the rotation axis. In other embodiments, other spacing retainers may also be present, which preferably form support surfaces or support lines in partial sections, such that the support lines or support surfaces are always present at the rearward end of the material web section 321, regardless of its length.

[0050] The preferred joining device 380 has only one conveying device S 340 for the segment group 504. The preferred joining device 380 is configured to position the material web section 321 around the segment group 504 and / or the joined segment group 504T at a maximum angle of 180°. In particular, the joining device 380 does not have a rolling device, especially not a rolling hand and / or a rolling belt and / or a rolling cam.

[0051] Figures 3 to 6 Various embodiments are shown in which material web sections 321 are adhered to section groups 504 to form joined section groups 504T. A receiving portion 332, particularly a recess, is shown in the conveying device P 330, wherein the material web sections 321 can be arranged on the bottom of the recess, for example, positioned by means of device 346, or not arranged on the bottom of the recess, such as... Figure 4 As shown in the image. Figures 3 to 6 The circle shown represents the cross-section of segment 504, to which material section 321 is adhered, joined and / or bonded to the segment group, thereby producing joined segment 504T.

[0052] Figure 3 and Figure 4 The offset between the receiving portion 332 of the conveying device P 330 and the receiving portion 342, particularly the groove, of the conveying device S 340 is shown. The receiving portion 332, particularly the groove, has a front side and a rear side. The offset between the receiving portions 332 and 342 creates a pressing area 347, where the material width segment 321 is pressed particularly strongly against the segment group 504. According to... Figure 3 The pressing area 347 is located on the rear side of the receiving part 332, and according to Figure 4 The pressing area 347 is located on the front side of the receiving part 332. (In accordance with...) Figure 5 In this embodiment, the pressing gap size 345 is smaller than the diameter of the cross-section of the segment group 504, thereby creating a pressing area 347 at the receiving bottom. Figure 6 The diagram illustrates another embodiment, namely an asymmetrically constructed receiving portion 332, particularly a groove, such that the pressing area 347 is constructed by protrusions in the receiving portion 332 or by the geometry of the receiving portion. In the case of an asymmetrically constructed receiving portion, the pressing area 347 can be centrally constructed on the front side and / or on the rear side. In a preferred embodiment, therefore, multiple pressing areas 347 exist in the receiving portion, particularly the groove. Figures 3 to 6 The implementation methods and the described variations can be additionally combined with each other, so that the conveying device P 330, for example, has from Figure 6 The receiving portion is asymmetrical, and the receiving portion 332 is offset relative to the receiving portion of the conveying device S 340. All other combinations, including multiple combinations, are also feasible and are disclosed as feasible embodiments.

[0053] The joined segments 504T are transferred from the conveyor S 340 to the rolling drum 350. An ejector 352 is arranged on the rolling drum 350, preferably directly after or adjacent to the transfer point from the conveyor S 340. The ejector 352 is preferably arranged in front of the rolling device 351, particularly the rolling hand 351 and / or the rolling cam 351. The ejector 352 is preferably constructed as a blowing device and has a collection container 353 for receiving the ejected, particularly blown, joined segments 504T. This ejector is particularly advantageous because, when using thicker material width segments 321, the covering of double-layered material width segments 321, particularly the joints of the material widths, can lead to errors during the rolling process. The joined segments 504T with double-layered material width segments 321 must be ejected in front of the rolling device. The joined segments 504T are wrapped on the rolling drum 350 by the rolling device 351, thereby producing segments 505 or 503U. Preferably, the machine 1 and / or the arrangement structure 600 and / or the joining devices 280, 380 have a control unit 10, which is connected to the material web providing device 210 and / or 310, especially to the control unit of the splicing device, in order to identify or track the splices in the material webs 211, 311, thereby ejecting the joined segments 503T and / or 504T, at least a portion of which has a splice portion, by means of the ejection device 252, 352. The preferred arrangement 600 includes a splicing device configured to connect output material webs 211, 311 to new material webs 211N, 311N at the overlapping area of ​​two material webs 211, 211N, 311, 311N. The arrangement includes a control unit 10 that controls the ejection device to eject joined segment groups 503T, 504T, having at least a portion of the overlapping area. The arrangement 600 preferably includes a sensor unit 11, preferably an optical sensor unit, which detects faulty joined segment groups 503T, 504T, especially those having at least a portion of the overlapping area, and is connected to the ejection device to eject the faulty joined segment groups 503T, 504T. The sensor unit 11 can be arranged adjacent to the conveyor devices S 240, 340 or adjacent to the rollers 250, 350. Figure 1 In this context, the sensor unit 11 is not explicitly shown in the second covering module 300, but it is preferably also present in the second covering module 300.

[0054] Since the embodiments of the first and / or second coating units 200, 300 have been described with reference to the reference numerals of the second coating device 300, the manufacturing method and manufacturing equipment will now continue from the rolling roller 250 of the first coating unit 200.

[0055] Following the rolling roller 250, the coated segment group 503U is braked on the braking roller 255 and the spacing is reduced, and then transported through the additional rollers 255 and 256 to the cutting roller 260, so as to divide the coated segment group 503 into two preferably symmetrical subgroups 503TG.

[0056] A circular cutter 262 and a grinding disc 263 are arranged adjacent to the cutting cylinder 260. The covered segments 503 and 503U are divided into two sub-groups 503TG by the circular cutter. The cutting on the cutting cylinder 260 can be used as a method according to... Figure 14 Cut under pressure or as according to Figure 13 and Figure 15 The cutting is performed under pressure. In the case of pressure-loaded cutting, the segments are held in the grooves of the cutting roller 260 by suction, so that the two sub-groups 503TG are axially offset by the circular blade 262 during and / or after cutting. This axial offset allows for very smooth cutting, and the sub-groups 503TG are not squeezed and / or pressed against the circular blade 262. Figure 13 As shown, after the segment 503U is cut into two sub-groups 503TG, a gap SP200 is created between the two sub-groups, so that the end faces of the two sub-groups 503TG do not contact and are spaced apart. Preferably, the gap SP200 is between 0.1 mm and 1 mm, or particularly preferably between 0.2 mm and 0.5 mm. In particular, the gap SP200 approximately corresponds to the thickness of the circular cutter 262, especially the maximum thickness of the portion of the circular cutter that contacts the end faces of the two sub-groups during the cutting process. Figure 14 Another embodiment is illustrated, namely, pressure-loaded cutting. Segment 503U is conveyed transversely to the axial direction on cutting roller 260 and divided into two sub-groups 503TG by a circular blade 262. When the circular blade engages with segment 503U and / or contacts the end faces of the two sub-groups 503TG, the segment 503U and the two sub-groups 503TG are preferably guided continuously and / or partially by two lateral guides SF1 and SF2, thus preventing axial displacement of the two sub-groups 503TG. Guiding is preferably achieved by a shaking device 261B. Once the sub-groups are disengaged from the cutting blade 262, the end faces of the sub-groups abut against each other. This cutting process can be advantageous in certain applications, such as for cutting tobacco-containing segments and / or segments composed of loose fibers, to prevent fibers and / or tobacco components from detaching from the end faces. The axial position of the sub-groups 503TG relative to the axial position of the segment 503U remains unchanged during this cutting process. In particular, pressure-loaded cutting can be advantageous when processing filter rods and / or robust segments.

[0057] After the cutting roller 260, transport to the reversing unfolding roller 399 is carried out by means of rollers 273, 274, and 276. Roller 276 is preferably configured as an accelerator roller to accelerate the two subgroups 503TG and / or change the pitch spacing, preferably by increasing the pitch spacing. The second covering module 300 from the reversing unfolding roller 399 to the rolling roller 350 has been described in detail in the preceding part of this application, so a detailed description of the second covering module 300 can be omitted here. The first and / or second covering modules 200, 300 can be configured with or without a supply section for the product bar segments 522, 522D, 523, 523D. All disclosed embodiments of the first and / or second covering modules 200, 300 can be implemented as any combination of the first covering module 200 and the second covering module 300 in the machine 1 or arrangement structure 600 and are considered to be disclosed in this application. In particular, the first and second covering modules 200, 300 are constructed differently or substantially the same.

[0058] Roller 350 transfers the covered segment group 505 to roller 370, wherein the segment group 505 consists of two subgroups 503TG, an intermediate double segment 523D, and a joined material width section 321, wherein the material width section 321 surrounds the segment group 505. Roller 370 is a laser supply roller that transports the segment group 505 transversely to the axial direction to laser rollers 371, 371'. Laser rollers 371, 371' preferably have rolling cams 372 or 372', thereby enabling perforation of the segment group in the entire circumferential direction. Laser rollers 371, 371' can be constructed as different laser rollers, for example, as laser rollers constructed according to German patent applications 10 2022 134675.7 and / or 102022 134 674.9.

[0059] Downstream, particularly directly downstream, of the laser rollers 371, 371' and / or the laser supply roller 370, a roller 364 is arranged. This roller is configured as a transport roller 364Tr and / or a rocking roller 364Tm for aligning the segment group 505 for subsequent cutting roller 360, and / or as a cleaning roller 364R. Embodiments of the cleaning roller 364 are described in a later part of this application.

[0060] Following the rolling drum 350 and / or the drum 364, the coated and perforated segment group 505 is preferably shaken and / or cleaned on the drums 364, 364Tm and transported to the cutting drum 360 to divide the coated segment group 505 into two preferably symmetrical subgroups and / or multiple tobacco products 531 and / or multiple product 530. The shaking or alignment of the segment group 505 can be performed by shaking the drum 364Tm or by shaking the drum 364Tm, or by shaking the device 361 on the cutting drum 360 upstream of the cutting blade 362, in addition to shaking the drum 364Tm.

[0061] A circular cutter 362 and an associated grinding disc 363 are arranged adjacent to the cutting cylinder 360. The covered segment group 505 is divided into two subgroups and / or multiple segments of product 530 and / or multiple segments of tobacco product 531 by the circular cutter 362. The cutting on the cutting cylinder 360 can be used as a method according to... Figure 14 Cut under pressure or as according to Figure 13 and Figure 16 The cutting is performed under pressure. In the case of pressure-loaded cutting, the segment group 505 is held in the groove of the cutting roller 360 by suction, such that the two sub-groups and / or multiple segments of product 530 and / or multiple segments of tobacco product 531 are axially offset by the circular blade 362 during and / or after cutting. This axial offset allows for very smooth cutting, and the sub-groups and / or multiple segments of product 530 and / or multiple segments of tobacco product 531 are not squeezed and / or pressed against the circular blade 362. Figure 13 and Figure 16 As shown, after segment 505 is cut into two sub-groups and / or multiple segments of articles 530 and / or multiple segments of tobacco articles 531, a gap SP300 is created between the two sub-groups, so that the end faces of the two sub-groups and / or multiple segments of articles 530 and / or multiple segments of tobacco articles 531 do not contact and are spaced apart. Preferably, the gap SP300 is between 0.1 mm and 1 mm, or particularly preferably between 0.2 mm and 0.5 mm. In particular, the gap SP300 approximately corresponds to the thickness of the circular blade 362, especially the maximum thickness of the portion of the circular blade that contacts the end faces of the two sub-groups during the cutting process. Figure 14Another embodiment is illustrated, namely, pressure-loaded cutting. Segment group 505 is conveyed transversely to the axial direction on cutting roller 360 and divided into two subgroups and / or multiple segments of product 530 and / or multiple segments of tobacco product 531 by circular blade 362. When the circular blade engages with segment group 505 and / or contacts the end faces of the two subgroups and / or multiple segments of product 530 and / or multiple segments of tobacco product 531, segment group 505 and the two subgroups and / or multiple segments of product 530 and / or multiple segments of tobacco product 531 are preferably guided continuously and / or partially by two lateral guides SF1 and SF2, thereby preventing axial displacement of the two subgroups 503TG. In other embodiments, lateral guidance is performed by a wobbling device 361B at the circular blade 362. Once the subgroups and / or multiple segments of product 530 and / or multiple segments of tobacco product 531 are disengaged from the cutting blade 362, the end faces of the subgroups abut against each other. This cutting process can be advantageous in certain applications, such as for cutting tobacco-containing segments and / or segments composed of loose fibers, to prevent the fibers and / or tobacco portions from detaching from the end face. The axial position of the sub-groups and / or multi-segment articles 530 and / or multi-segment tobacco articles 531 with respect to the axial position of the segment group 505 remains unchanged during this cutting process. In particular, pressure-loaded cutting can be advantageous when processing filter rods and / or robust segments.

[0062] The cut subgroups and / or multiple product segments 530 and / or multiple tobacco product segments 531 are transferred from the cutting roller 360 to subsequent rollers 373, 373R, 374, 374R, 375 and continue to be conveyed. Roller 373 is preferably a transport roller or a cleaning roller 373R. Roller 374 is preferably a conical unfolding roller or a cleaning roller 374R or a combination of these two rollers, i.e., a conical unfolding-cleaning roller. Roller 375 is preferably a conical unfolding roller or a cleaning roller 374R or a combination of these two rollers, i.e., a conical-unfolding cleaning roller. The two subgroups and / or multiple product segments 530 and / or multiple tobacco product segments 531 are axially spaced by the conical unfolding roller for transfer to the inspection transfer module 400.

[0063] The inspection transfer module 400 is constructed and set up for inspecting a single-layer product flow and transferring it to subsequent machines, such as an RTS section for transporting a multi-layer mass flow on a conveyor belt and / or a packaging machine for packaging rod-shaped products in a package.

[0064] The inspection transfer module 400 has a transfer roller 401, which is preferably constructed as a transport roller 401 or a cleaning roller 401R. Behind the transfer roller 401 is a measuring roller 402, for example, for measuring the performance of rod-shaped articles, such as subgroups and / or multi-segment articles 530 and / or multi-segment tobacco articles 531. End-face inspection and / or surface inspection of the article's coating is preferably performed. The inspection transfer module 400 has an inspection roller 403, behind which are two sensor rollers 406 and 407. Sensor rollers 406 and 407 are constructed and configured to perform at least one of the following measurement tasks: end-face inspection, surface inspection of the article or multi-segment tobacco article's coating, integrity inspection, and / or incorrect segmentation inspection.

[0065] Inspecting roller 403 Figure 17The diagram is schematically shown in a side view. Rod-shaped products, particularly multi-segment cigarette products 531 and 530, are transferred at transfer point 4013 onto inspection roller 403 into receiving groove 4012. Inspection roller 403 rotates in the rotational direction and conveying direction 4015. Preferably, inspection roller 403 has three inspection stations 4016, 4018, and 4017. After inspecting the rod-shaped products, particularly multi-segment products 530 or multi-segment cigarette products 531, the rod-shaped products are transferred at output point 4014 to subsequent roller 406. If the rod-shaped product does not correspond to the inspection preset, it is subsequently ejected. Inspection roller 403 has a pitch 4019, which is preferably 4π, 6π, 8π, or 10π (mm) or an integer multiple (mm) of pi (π). The first inspection station 4016 (located between the third inspection station 4018 and the second inspection station 4017) is used to measure the ventilation level of the rod-shaped product. The third inspection station 4018 (arranged downstream of the first inspection station 4016 along the conveying direction 4015) is used to measure the sealing level of the rod-shaped product. The second inspection station 4017 (arranged upstream of the two inspection stations 4016 and 4018) is used to measure the tensile strength of the rod-shaped product. Given the very high conveying speed of the inspection roller 403 and therefore the short time spent at the respective inspection stations, it is necessary to build up the corresponding pressure, such as overpressure, in the rod-shaped product within a short time window. If the corresponding pressure has already been applied to the end or one end of the cigarette product beforehand, for example, at the second inspection station 4017, the quality of the measurements of ventilation and sealing level is significantly improved. The pressure can be applied within the pitch 4019 or within the distance between the receiving groove and the next receiving groove 4012, but it can also be applied within multiple, preferably at least or exactly two, three, or four pitches 4019. Preferably, the second inspection station 4017 extends over multiple, particularly at least two, three, or four receiving grooves 4012. In particular, in the case of rod-shaped articles 531, 530 having perforations and, in particular, paper segments and / or thick paper coverings, dust particles are blown out from the perforation openings or holes in inspection stations 4017, 4016, 4018, which may contaminate the inspection roller 403 and / or subsequent equipment components, particularly sensor devices and sensor inspection devices. Advantageously, a withdrawal device 4020 is provided, preferably configured to withdraw a cover and overlap the area above inspection stations 4017, 4016, 4018. The extraction device 4020 has at least one extraction area 4021, 4022, 4023 for extracting dust particles. In other embodiments, the roller 403 can be constructed simply as a cleaning roller 403R, and in this embodiment there is no inspection station. An inspection roller 403 with a cleaning function is also understood as a cleaning roller.Cleaning rollers 403R, 364R, 373R, 374R, and 375R have corresponding equipment to blow out and extract dust from the inside of rod-shaped products, especially through perforated openings.

[0066] Figure 18 A cross-section of a cleaning roller (403R, 364R, 373R, 374R, 375R) and / or an inspection roller 403 with an extraction device 4020 is shown. Rod-shaped articles 530, 531 arranged in a receiving recess 4012 are cleaned by compressed air applied to their end sides. Particulate dust is extracted by the extraction device 4020. The extraction device 4020 can be connected to a negative pressure source through at least one extraction region 4021, 4022, 4023. Preferably, the extraction device 4020 is configured such that it can draw in side air to generate an extraction airflow. Figure 19 and Figure 20 This was shown from two other perspectives. Figure 18 The device shown is provided, but specific details are not shown for clarity, such as... Figure 19 The extraction device is preferably located near the perforated arrangement of the articles to be cleaned and / or inspected. The extraction device is preferably segmented. The cleaning rollers and / or inspection rollers are preferably constructed with double tracks. The cleaning rollers and / or inspection rollers are preferably constructed with two rows of receiving portions, particularly grooves, arranged side-by-side for receiving and inspecting and / or cleaning rod-shaped articles, i.e., the first row A 4051 and the second row B 4052. Each row preferably has its own extraction device 4020. The first row A 4051 and / or the second row B 4052 preferably have extraction devices 4020. The extraction devices of the first row A 4051 and the second row B 4052 are preferably constructed separately from each other.

[0067] Other equipment used to prevent fouling is a collection container AFB, wherein the collection container AFBS is preferably arranged adjacent to the cutting roller, and / or wherein the collection container AFBT is preferably adjacent to the roller, especially adjacent to a roller arrangement directly behind the cutting roller. Figure 21 The text shows information from... Figure 1 The cut-off portion shows supply modules 120 and 130 with collection containers AFBT and ABFS. These collection containers are arranged adjacent to rollers 122 and 124. These collection containers can also be arranged in supply module 130 or in the supply modules of covering units 200 and 300, but... Figure 21 It is not explicitly shown in the text. Figure 22Exemplary examples are shown of rollers 122 and 124, wherein collection containers AFB, AFBT, and AFBS are arranged adjacent to rollers 122 and 124. Collection container AFB is constructed as a single-sided open disc with an opening OE_AFB facing the peripheral side of rollers 122 and 124. The roller has a receiving portion, particularly a groove, for receiving rod-shaped articles. The opening of the collection disc is at an angle range αAFB, which is 80° in this illustration. This extended opening allows for the collection of corresponding article segments or particles. The distance A_AFB between rollers 122 and 124 and collection container AFB is the minimum distance between the rollers and the collection container, which in the illustrated embodiment approximately corresponds to 4 cm. This distance allows the collection containers to collect article segments and particles without missing the opening of the collection container due to a long trajectory. The collection container is preferably constructed as a pull-out drawer for emptying the collected article segments and particles or for cleaning. Preferably, the collection container has a pull-out unit for emptying or cleaning the collection container.

[0068] The inspection and transfer module 400 has a discharge roller 408 that transversely conveys multiple sections of products 530 or multiple sections of tobacco products 531 in the axial direction. Adjacent to the discharge roller 408 is a removal roller 409, constructed and configured to remove and eject each section of product 530 or multiple sections of tobacco products 531. The inspection and transfer module 400 has an insertion roller 410 to transfer a single-layer conveyor flow of two tracks consisting of multiple sections of products 530 and / or multiple sections of tobacco products 531 to a single-layer conveyor flow of one track consisting of multiple sections of products 530 or multiple sections of tobacco products 531 by means of a redirection roller 411 (preferably constructed as a conical reversing device or a tip-turning drum of different types). Here, the pitch of the receiving section and / or the conveyed multiple sections of products 530 or multiple sections of tobacco products 531 is halved. If the discharge roller 408 has, for example, a pitch (groove spacing) of 8π, then the insertion roller 410 has a pitch of, for example, 4π. To ensure smooth upward transport of the multi-segment products 530 or multi-segment tobacco products 531, the inspection transfer module 400 has transport rollers 412 to 418. The single-layer conveyor flow consisting of the multi-segment products 530 or multi-segment tobacco products 531 is transferred to a multi-layer conveyor flow via the transfer-discharge roller 420 and transported to a subsequent machine or a subsequently located storage location.

[0069] exist Figure 23The image shows a schematic perspective view of an extraction system 4200 for cleaning rollers, presented in fragment form. This extraction system 4200 is a component of a machine used in the manufacture of rod-shaped products (such as multi-segment products, multi-segment tobacco products, or multi-segment intermediate products) for the tobacco processing industry. The extraction system 4200 has a conduit 4210, which is subjected to negative pressure, for example, by a negative pressure source (not shown) on the machine side. At the end, the conduit 4210 is configured with two pipe sections 4211 and 4212, which respectively apply negative pressure to slide-shaped, guide-shaped, or curved extraction shields 4221 and 4222.

[0070] Pull-out covers 4221 and 4222 are arranged on the outer side of the cleaning roller (not shown) in the area of ​​each row of rod-shaped products (which are conveyed transversely along the circumferential direction of the cleaning roller). Within the conveying section (where the pull-out covers 4221 and 4222 are arranged), at least one or more inspection stations can be arranged for a row of rod-shaped products (such as multi-segment products, multi-segment tobacco products, or multi-segment intermediate products) conveyed on the cleaning roller. The inspection stations can be configured, for example, as follows: Figure 17 As shown in the inspection stations 4017, 4016, and 4018.

[0071] Within the framework of this invention, it can be specified that each of the extraction shields 4221, 4222 overlaps the area above the corresponding inspection station. By effectively applying negative pressure in the extraction shields 4221, 4222, dust or dust particles from inside the rod-shaped products are extracted from the area of ​​the conveying section for each row of rod-shaped products conveyed on the cleaning roller.

[0072] In one design, the extraction covers 4221, 4222 are rotatably supported so that they can be easily swayed away from the cleaning roller (e.g., for maintenance), thereby improving the accessibility of the extraction covers 4221, 4222 and the cleaning roller. Furthermore, in an improved design, the extraction system 4200 has a locking device 4250 for the rotatable extraction covers 4221, 4222, such as a quick-change locking element or a quick-locking system, so that the extraction covers 4221, 4222 can be reliably and permanently positioned at the cleaning roller for the operation of the cleaning roller and / or the machine. This results in reliable operation of the extraction system 4200.

[0073] exist Figure 24Another perspective view of the cleaning roller 4030 is shown in fragment form. The cleaning roller 4030 has supports 4310 and 4320 in a conveying area (where inspection stations for inspecting rod-shaped products are arranged and / or where pull-out covers are arranged on the outer side for each row of rod-shaped products conveyed on the cleaning roller 4030), each support contacting a pull-out cover. The respective supports 4310 and 4320 are configured to guide and / or position the pull-out covers that work in conjunction with them. Thus, for example, the respective pull-out covers can be positioned in a fixed position with a predetermined distance from the outer side of the roller. The supports 4310 and 4320 are held at the cleaning roller 4300 by brackets 4311 and 4321, respectively.

[0074] Supports 4310 and 4320 have radially outwardly projecting protrusions 4315 and 4316 for positioning the corresponding extraction covers, these protrusions contacting the corresponding extraction covers. Supports 4310 and 4320 are advantageously arranged above receiving grooves for rod-shaped articles and are preferably constructed with bends. The undersides of supports 4310 and 4320 are used to guide the conveyed rod-shaped articles, wherein the rod-shaped articles are guided along the corresponding supports 4310 and 4320 as the cleaning roller 4300 rotates.

[0075] During the transverse conveying of the rod-shaped articles, the retaining negative pressure in the receiving groove of the cleaning roller 4300 is reduced or decreased in the conveying area of ​​the corresponding extraction shroud (not shown). In this conveying area, the tensile strength and / or sealing and / or ventilation of the rod-shaped articles can be determined by the corresponding inspection station. To measure or determine these values, the retaining negative pressure for the rod-shaped articles in this conveying area is reduced, particularly by at least 25% or at least 50% to 70% or 75%. The retaining negative pressure in the receiving groove is increased before the conveyed rod-shaped articles enter and / or after they exit the conveying area.

[0076] In addition, in one design, the cleaning roller 4300 has a grooved roller ring 4330 for each row of rod-shaped products, which can be removed individually, for example, for cleaning the roller ring 4330.
