Description

Technical Field

[0001] This invention relates to a push roller for the tobacco processing industry.

[0002] The present invention also relates to a machine for the tobacco processing industry, particularly a filter tip production machine or filter tip assembly machine, and a filter tip segment supply device for providing filter tip segments made of filter rods. Background Technology

[0003] Conveyor rollers are used in tobacco processing machinery, especially filter tip attaching machines, or machines used to produce various smoking products, such as heat-resistant products or electronic cigarettes, to convey cigarettes, filter blocks, or their components.

[0004] In the production of cigarettes, filters, and filtered cigarettes, or so-called heat-noncombustible products or electronic cigarettes, the aforementioned rod-shaped articles are generally conveyed in modern tobacco processing manufacturing machines by means of conveying rollers. The rollers, or their shells or bodies, are provided with grooves or receiving cavities for receiving the rod-shaped articles (cigarettes, filter rods or filter plugs, filtered cigarettes) for transverse axial conveying. In this case, the receiving cavity has a bottom. During conveying, the rod-shaped articles in the tobacco processing industry are generally arranged in rows transversely back and forth within the receiving cavity.

[0005] Furthermore, push rollers are also known as conveyor rollers, for example, in filter tip supply devices on filter tip attaching machines, where filter plugs are longitudinally pushed as rod-shaped articles. In this case, filter rods of multiple lengths are taken out from the filter rod magazine on a filter tip supply device with multiple conveyor rollers and cut into filter plugs of double length on a cutting roller. After cutting, the filter plugs are staggered on an interleaving roller, that is, each cut filter plug is individually arranged offset from the next filter plug in a recess of the interleaving roller. Immediately afterwards, the staggered filter plugs are longitudinally pushed on the push roller in a receiving cavity in another method step, so that the filter plugs are then aligned front to back in a row along the transverse direction, thereby transferring the rows of aligned filter plugs from the push roller to the next conveyor roller.

[0006] Rollers are commonly used in the mass production of filter rods and cigarette filters, in which multiple lengths of filter rods are prepared in a so-called transverse method, that is, transverse to their longitudinal axis, by one or more subdivisions, staggers, and front-to-back arrangements, for subsequent connection with other filter components or smoking product components.

[0007] EP 1013181A2 discloses a push / cut roller in which a smoking article component or filter block is pneumatically pushed toward a stop in a receiving cavity by applying suction air to a suction hole in the receiving part.

[0008] GB 2267021A describes a filter tip assembly machine in which filter rods are removed from two compartments respectively. After removing the first filter rod, it is centered, cut, and moved laterally apart. A second filter rod from the other compartment is then centered between sections of the first filter rod. The filter rod assemblies are subsequently cut, staggered, and moved separately on rollers. The process of "cutting, staggering, and moving the filter blocks" is repeated and therefore performed twice in total. The combined filter tip produced from the two different filter rods is then transferred to an assembly roller containing cigarette sticks.

[0009] In addition, DE 102013210634A1 discloses a push roller for a machine used in the tobacco processing industry. Summary of the Invention

[0010] The object of the present invention is, for example, to provide a pusher roller for a filter tip supply device, wherein, in particular, it is capable of reliably pushing short rod-shaped articles in segments longitudinally.

[0011] This task is solved by a push roller for the tobacco processing industry, which has a roller body with receiving cavities arranged in rows along the circumferential direction of the roller body for rod-shaped articles, especially filter rods and / or filter blocks and / or segmented products in the tobacco processing industry. The roller body is rotatable about a rotation axis. Each receiving cavity has a cavity bottom, which is defined by a cavity side strip extending forward and a cavity side strip extending backward along the conveying direction of the push roller. The cavity side strips extend parallel to the rotation axis of the push roller.

[0012] In this configuration, at least in the conveying area of ​​the rod-shaped article on the pushing roller, the receiving cavity is laterally defined by a stop barrier having a stop surface for the rod-shaped article.

[0013] Among them, rod-shaped articles having, in particular circular or annular, cross-sectional surfaces along the edge strip and bottom of the cavity are preferably pneumatically moved or pushed towards the stop barrier in the receiving cavity along the longitudinal axis, especially during the rotation of the pusher roller.

[0014] The receiving cavity has a cross-section with a cross-sectional surface that is defined by the cavity bottom and the cavity edge strip.

[0015] The stop surface of the stop barrier faces the articles that can be arranged or are arranged in the receiving cavity, wherein the stop surface of the stop barrier is equal to or greater than the cross-sectional surface of the rod-shaped article facing the stop barrier, and / or the stop surface of the stop barrier is equal to or greater than the cross-sectional surface of the receiving cavity facing the stop barrier.

[0016] Furthermore, an airflow channel with a bend is constructed in the area of ​​the stop barrier, so that air that can be transported or transported from the receiving cavity is guided around the stop barrier.

[0017] This invention is based on the concept that, for an article or article segment to be moved or moved in a receiving cavity, lateral stops are provided on all surfaces by a stop barrier in the receiving cavity, wherein the stop surface for a rod-shaped article in the receiving cavity is greater than or equal to the cross-sectional surface of the stop surface of the rod-shaped article facing the stop barrier, or the stop surface for the rod-shaped article is equal to or greater than the cross-sectional surface of the receiving cavity. This provides complete stops on all surfaces for the rod-shaped article to be moved, wherein, for example, when the rod-shaped article is moved longitudinally in the receiving cavity, it works in conjunction with the airflow channels in the area of ​​the stop barrier to reduce or prevent the falling of filling material from the rod-shaped article or article segment. For example, the rod-shaped article or article segment has refurbished or reconstituted tobacco material as filling material.

[0018] In one design, stop barriers for pushing rod-shaped articles are fixedly arranged on a pushing roller relative to a rotary-driven roller body. In an alternative design, receiving cavities each have stop barriers arranged within the receiving cavities, which rotate together with the roller body as it rotates.

[0019] The stop barrier restricts the lateral movement of the rod-shaped article within the receiving cavity, allowing it to be transferred from that position to the next conveyor roller in a separate step after the rod-shaped article has been arranged and positioned on the stop surface of the stop barrier.

[0020] In one design of the push roller, a stop barrier is arranged between the ends of the receiving cavity. According to another or additional embodiment, the stop barrier is arranged laterally on one end of the receiving cavity.

[0021] By constructing an airflow channel with a bend in the region of the stop barrier, especially a suction airflow channel, a negative pressure is applied to the bend airflow channel during the pushing of the rod-shaped article in the receiving cavity. The negative pressure acts at the head end of the rod-shaped article facing the stop barrier, wherein, based on the negative pressure between the head end of the article and the stop barrier, the rod-shaped article moves toward the stop barrier and is positioned on the lateral stop barrier.

[0022] In one design, the airflow channel can branch off from the bottom of the cavity in the area of ​​the stop barrier via a slit or similar portion in the roller body and be subjected to negative pressure from a negative pressure source. In another design, the airflow channel can also be constructed above the stop barrier, for example, between the cover for receiving the cavity and the stop barrier.

[0023] By constructing a stop barrier with stop surfaces on all sides, an airflow channel with curved portions is provided in the region of the stop barrier, such that, for example, drawn air is guided around the stop barrier. The airflow channel is configured, according to another aspect, as an airflow channel surrounding the stop barrier, for example, through a recess in the bottom of the receiving cavity or through a portion of the space in a cover above the receiving cavity. In one design, the airflow channel is constructed in the bottom of the receiving cavity, such that the airflow channel below the stop barrier is configured as a lower flow channel. According to other, particularly alternative or other embodiments, the airflow channel is constructed above the stop barrier or also laterally in at least one or both cavity side strips defining the bottom of the receiving cavity.

[0024] According to another aspect, the conveying roller is arranged such that a fixed-position cover for receiving a cavity is arranged on the conveying roller in the conveying area of ​​the rod-shaped articles, wherein the cover extends and bends along the circumferential direction of the conveying roller. The cover is arranged, in particular, on the conveying roller in the conveying area, in which the longitudinal axial movement of the rod-shaped articles in the receiving cavity is carried out. Preferably, the receiving cavity is constructed in a basin shape, wherein, in particular, the cavity side strip has a (radial) height such that the cavity side strip extends beyond the rod-shaped articles arranged in the receiving cavity.

[0025] By arranging a cover, during the conveying of rod-shaped articles, such as in segments, negative pressure is not applied to the rod-shaped articles within the conveying area of ​​the cover. This is achieved by shutting off the holding air or maintaining negative pressure in the receiving cavity within the conveying area of ​​the cover, and by applying suction air with longitudinal action to push the rod-shaped articles in the receiving cavity, causing the rod-shaped articles to move toward the stop barrier in the longitudinal direction. Thus, the rod-shaped articles are moved toward or drawn toward the stop by means of the longitudinally acting pushing suction air.

[0026] Furthermore, in an improvement to the push roller, the roller body is configured such that it has a groove with a bottom that surrounds the roller in the circumferential direction for receiving a stop barrier. The radial distance between the bottom of the surrounding groove and the axis of rotation of the push roller is less than the radial distance between the bottom of the receiving cavity and the axis of rotation of the push roller. Based on the smaller radial distance between the bottom of the surrounding groove and the axis of rotation of the push roller compared to the radial distance between the bottom of the groove and the axis of rotation of the push roller, the stop barrier is arranged in the groove, wherein the lower edge of the stop barrier is positioned in the groove, and the lower edge of the stop barrier is located deeper than the bottom of the receiving cavity. In this case, to construct an airflow channel, a recess or similar portion is constructed in the region of the stop barrier, below the lower edge of the stop barrier, in the receiving cavity or in the roller body, to construct an airflow channel below the lower side of the stop barrier.

[0027] Furthermore, according to an improved arrangement, the stop barrier is preferably fixedly positioned relative to the rotating or rotatable roller body in the conveying area of ​​the rod-shaped article, within a groove surrounding the roller body. Specifically, the stop barrier with a lower edge is arranged in the groove such that its lower edge is closer to the axis of rotation of the pushing roller than the bottom of the receiving cavity. At least a portion of this airflow channel is constructed within the roller body below the lower side of the stop barrier.

[0028] Furthermore, in one improvement of the roller body, an airflow channel is constructed in the bottom of the corresponding receiving cavity in the area of ​​the stop barrier.

[0029] Furthermore, one design of the push roller is characterized in that the cover is held on the push roller by means of a cover holder and / or the stop barrier is held on the push roller by means of a stop barrier holder, or the cover and the stop barrier are held on the push roller by means of a common holder, or the stop barrier is arranged on the cover, or the cover is arranged on the stop barrier.

[0030] According to another aspect and one embodiment, it is advantageous in the push roller that each receiving cavity has a stop barrier for rod-shaped articles.

[0031] Furthermore, in one design of the conveyor roller, it is advantageous that the airflow channel is arranged between the stop barrier and the bottom of the corresponding receiving cavity and / or the front and / or rear side strips of the corresponding receiving cavity. Additionally, according to an improvement, the airflow channel is constructed between the corresponding stop barrier and the cover of the receiving cavity.

[0032] In order to construct an airflow channel above or on the stop barrier arranged in the receiving cavity, an improvement of the push roller is configured such that the cover has a radially outward shaped portion or a radially outward shaped protrusion in the region of the stop barrier of the receiving cavity.

[0033] Furthermore, this task is accomplished by a tobacco processing machine, particularly a filter production machine or filter assembly machine, which is constructed with the push rollers described above.

[0034] Furthermore, this task is solved by a filter rod segment providing device for providing filter rod segments manufactured from filter rods, wherein the filter rods and / or filter rod segments are transversely conveyed or conveyable on the filter rod segment providing device, which is constructed with the push rollers according to the invention described above. To avoid repetition, reference is explicitly made to the preceding description.

[0035] Other features of the invention will become apparent from the description of embodiments according to the invention, taken in conjunction with the claims and drawings. Embodiments according to the invention may satisfy a single feature or a combination of multiple features. Attached Figure Description

[0036] The invention is described below with reference to the accompanying drawings, without limiting the general inventive concept, wherein all details of the invention not set forth in detail herein are explicitly referred to in the drawings. Wherein:

[0037] Figure 1 A schematic perspective view of a conveying roller for conveying rod-shaped articles in the tobacco processing industry, according to the present invention, is shown.

[0038] Figure 2 It shows Figure 1 A schematic, non-scale cross-section of the pushing roller and Figure 3 The clip shows a schematic top view of a receiving cavity of the push roller.

[0039] Within the scope of this invention, features marked with "especially" or "preferred" are understood as optional features.

[0040] In the accompanying drawings, elements and / or parts of the same or identical form are given the same reference numerals, so there is no need to reintroduce them separately. Detailed Implementation

[0041] Figure 1 A perspective view of the push roller according to the present invention is shown. Figure 2The diagram shows a schematic, non-scale cross-sectional view of the push roller 10. The push roller 10 has an outer roller body 12 with a receiving cavity 14, and the roller body is rotatably driven about a rotation axis R. The roller body 12 surrounds a control body 11 disposed inside the push roller 10, which controls the suction air supplied at corresponding bores in the roller body 12, by means of which the rod-shaped article A is held or moved longitudinally within the receiving cavity 14.

[0042] The roller body 12 has a receiving cavity 14 in the circumferential direction. The rod-shaped article A is received into the receiving cavity from the conveying roller arranged upstream, and the rod-shaped article A is pushed in the receiving cavity 14 in the longitudinal direction, that is, parallel to the rotation axis R of the pushing roller 10.

[0043] In this case, the push roller 10 is part of a roller system, such as a filter tip supply device or a filter tip acceptor or similar device. The received rod-shaped article A, such as a filter rod segment or filter rod, is conveyed in the transverse direction by means of the push roller 10, wherein, during the transverse conveying of the rod-shaped article A on the push roller 10, the rod-shaped article A is pushed in the longitudinal direction in the conveying area within the receiving cavity 14.

[0044] The push roller 10 has a cover 16 on its outer surface in the conveying area where the rod-shaped article A is longitudinally pushed in the receiving cavity 14. The cover 16 partially or completely covers the conveying area where the rod-shaped article A is longitudinally pushed in the receiving cavity 14. For example, the cover 16 is made of plastic, such as polyethylene (PE), or other flexible or formable materials.

[0045] In the conveying zone, a cover 16 is arranged on the outer side of the push roller 10, in which the rod-shaped article A received is pushed longitudinally in the receiving cavity 14, wherein the cover 16 is arranged on the outer side of the push roller 10 via a retainer 160.

[0046] As from Figure 2 As can be seen in the cross-sectional view, the receiving cavity 14 has an air suction hole 18, which is subjected to negative pressure in the conveying region, in which the rod-shaped article A arranged in the receiving cavity 14 is longitudinally pushed. In this case, the air suction hole 18 is constructed on one end of the receiving cavity 14.

[0047] Figure 3The fragment schematically shows a top view of a receiving cavity 14 of the conveying roller 10. The receiving cavity 14 has a cavity bottom 141, which is bounded about the conveying direction of the conveying roller by a front cavity side strip 143 and a rear cavity side strip 142. An air suction bore 18 is thus constructed in the cavity bottom 141 of the corresponding receiving cavity 14.

[0048] Furthermore, the concave side strips 142 and 143 have circumferential grooves 20 along the circumferential direction of the pushing roller 10 or the roller body 12 (see...). Figure 2 In this conveying region, a stop plate 22 is arranged as a barrier for the rod-shaped article A, which is longitudinally pushed within a receiving cavity 14. The rod-shaped article A to be pushed is received in the receiving cavity 14 on one side of the stop plate 22, opposite to the side of the stop plate 22 facing the suction air borehole 18. In other words, the stop plate 22, which forms a barrier, is arranged between the suction air borehole 18 and the rod-shaped article A (to be pushed).

[0049] The surrounding groove 20 has a groove bottom in this case, and the radial distance between the groove bottom and the rotation axis R of the push roller 10 is less than the radial distance between the cavity bottom 141 of the receiving cavity 14 and the rotation axis.

[0050] A stop plate 22 is arranged in a groove 20 on the push roller 10 in the conveying area of ​​the rod-shaped article A, in which the rod-shaped article A is pushed longitudinally in the receiving cavity 14, such that the radial distance between the lower side of the stop plate 22 and the axis of rotation R is less than the radial distance between the cavity bottom 141 of the receiving cavity 14 and the axis of rotation R. Furthermore, a lower flow channel 24 is constructed below the stop plate 22 in the area of ​​the stop plate 22 and in the area of ​​the cavity bottom 141 of the receiving cavity 14, such that air is drawn through the lower flow channel 24 by applying a suction air hole 18 in the conveying area (where the rod-shaped article A is pushed longitudinally), wherein the stop plate 22 in this case acts as a stop barrier for the rod-shaped article A, causing the rod-shaped article A to move toward the stop plate 22 with one end face facing it.

[0051] The stop plate 22 provides lateral stops for all faces of the rod-shaped article A, wherein the stop face facing the rod-shaped article A is larger than the cross-sectional surface of the rod-shaped article A, or larger than the cross-sectional surface of the receiving cavity 14 between the cavity side strips 142, 143 and the cavity bottom 141.

[0052] The stop plate 22 is partially annularly constructed along the circumferential direction of the push roller 10 and is disposed on the push roller 10 together with the cover 16 and held on the retainer 160. In one design (not shown), the stop plate 22 is annularly constructed.

[0053] In order to hold the rod-shaped article A, which is arranged on the stop plate 22 after being pushed along its longitudinal axis, in the receiving cavity 14, a holding air hole 26 is provided in the roller body 12, such that the rod-shaped article A is held on the holding air hole 26 by applying negative pressure through the holding air hole 26 constructed in the roller body 12 and is conveyed towards the turning point to the next conveying roller as the pushing roller 10 rotates. In this case, the holding air hole 26 is constructed in the cavity bottom 141 of the receiving cavity 14.

[0054] An additional lateral stop 122 is arranged on the end of the receiving cavity 14 opposite to the air suction bore 18, wherein the lower edge of the stop 122 has a smaller radial distance to the rotation axis R than the radial distance between the cavity bottom 141 of the receiving cavity 14 and the rotation axis. Furthermore, an airflow channel 124 is constructed in the region of the stop 122 of the receiving cavity 14, allowing air to flow between the roller body 12 and the stop 122. The airflow channel 124 is laterally connected to the ventilation bore 28. Additionally, the airflow channel 124 is connected to the air suction bore 30.

[0055] When the rod-shaped article A moves toward the stop plate 22 in the receiving cavity 14, the corresponding suction air hole 18 of the receiving cavity 14 is opened by means of the control body 11 arranged inside the roller body 12, so that during the longitudinal axial pushing movement of the rod-shaped article A in the receiving cavity 14 while the suction air hole 30 is closed and the ventilation hole 28 is open, the suction air hole 18 is subjected to negative pressure, so that air flows into the receiving cavity 14 through the ventilation hole 28 and the air flow channel 124 (in succession).

[0056] Article A is received in receiving cavity 14, wherein the corresponding ventilation hole 28 is closed. Suction air from hole 30 positions article A on stop 122 by means that cover 16 is either open or closed above suction air hole 18, thereby allowing air to flow there sequentially. Or it may be flowed sequentially. The suction air is activated at a time staggered with the time of the suction air borehole 30 in the control body 11. Immediately afterwards, the control body 11 opens the suction air supply for the suction air borehole 18 and closes the cover 16 above it and opens the ventilation borehole 28, so that the article A is positioned on the stop 22.

[0057] In order to facilitate the longitudinal axial movement of the rod-shaped article A in the receiving cavity 14, in another design, a corresponding ventilation hole or similar part is provided in the cover 16.

[0058] All features mentioned, including those individually derived from the accompanying drawings and those disclosed in combination with other features, are considered essential to the invention, whether individually or in combination. Embodiments of the invention can be accomplished by a single feature or a combination of multiple features.
