Description

[Technical field]

[0001] The present invention relates to an apparatus for assembling an aerosol-generating article, a method for manufacturing an aerosol-generating article, and the use of a spacer in an apparatus for manufacturing an aerosol-generating article. [Background technology]

[0002] WO 2021 / 123425 discloses a packaging apparatus and method for wrapping a sheet around a group of segments. WO 2021 / 165509 discloses an aerosol-generating article having a rod and a filter arranged in a spaced apart relationship, and a method for producing the same.

[0003] There is a need for an improved assembly of an aerosol-generating article having a gap between the rod and the filter. Summary of the Invention

[0004] According to a first aspect of the present invention there is provided an apparatus for assembling an aerosol-generating article, the apparatus comprising a conveyor having a support surface for supporting at least two axially aligned rod-shaped segments of the aerosol-generating article, the apparatus further comprising a spacer, the apparatus configured to move the spacer from a stored position to an operative position, in which the spacer provides abutment means for the rod-shaped segments on the support surface.

[0005] In particular, the spacer provides abutment means for two rod-like segments disposed on either side of the spacer in the operative position.

[0006] The device may comprise several aligned spacers, which may be arranged alternately with several axially aligned rod-shaped segments. In particular, the device may comprise two aligned spacers, which may be arranged alternately with three aligned rod-shaped segments.

[0007] In the operating position, the spacer may be disposed between the rod-shaped segments, in particular so that the rod-shaped segments do not contact each other. Moving the spacer to the stored position may provide a gap between the two rod-shaped segments. The gap between the rod-shaped segments may result in less rod-shaped segment material being used. Thus, the apparatus may reduce material costs and increase sustainability. Using the apparatus, an aerosol-generating article having a gap between two rod-shaped segments may be formed in fewer process steps compared to conventional methods.

[0008] The aerosol-generating article may be a combustible cigarette or an article for use in a heat-not-burn device. One of the rod-shaped segments may be an aerosol-generating rod. The aerosol-generating rod may contain an aerosol-generating substrate, in particular tobacco, herbs, oils, or an artificial substrate. One of the rod-shaped segments may be a filter or a hollow tube, in particular made of acetate tow, such as a cigarette filter. The consumer may consume the aerosol-generating article by burning. During burning, the aerosol-generating rod may burn and the burning area of ​​the aerosol-generating rod may come close to the filter. This may cause burning or excessive heating of the filter, which may have a negative effect on the taste of the smoke. A gap between the filter and the rod may prevent such effects. In heated non-combustion devices in which the aerosol-generating article may be heated rather than combusted, the aerosol-generating rod may be heated to about 300 degrees Celsius or more, and the space between the aerosol-generating rod and the filter may advantageously provide space in which the aerosol can cool, condense, and nucleate before passing through the filter and into the user's mouth.

[0009] The conveyor may comprise a spacer. The conveyor may comprise a storage cavity for accommodating the spacer at least when the spacer is in the stored position. The storage cavity may have substantially the same size as the spacer. The storage cavity may be larger than the spacer such that the storage cavity may accommodate other components in addition to the spacer.

[0010] In the stored position, the spacers may be flush with or below the support surface. Such a configuration may allow a sheet, particularly a wrapper, to be wrapped around the rod-shaped segment without interference from the spacers. In the operating position, the spacers may protrude from the support surface.

[0011] A plunger or guiding surface may be provided to press one or both rod-like segments against the spacer in the operating position. The guiding surface may be stationary. The stationary guiding surface may extend at least partially along the circumference of the drum, and the stationary guiding surface may be inclined with respect to the axial direction. The rod-like segment may be moved relative to the guiding surface such that the guiding surface presses the rod-like segment against the spacer. The plunger or guiding surface may engage a distal end of the rod-like segment, while a proximal end of the rod-like segment contacts the spacer. As an alternative to a guiding surface or plunger, the rod-like segment may be pressed against the spacer by air pressure. The device may comprise an air nozzle. The air nozzle may be adapted to apply air pressure to the rod-like segment or to a plurality of rod-like segments such that the rod-like segment or to a plurality of rod-like segments is pressed against the spacer.

[0012] The spacer may have a width of 1 mm to 15 mm, in particular 1 mm to 4 mm. Such a value may provide a sufficiently large gap between the rod-shaped segments. The width of the spacer may correspond to the gap formed between the rod-shaped segments, in particular the distance between the rod-shaped segments. The width of the spacer may be measured in the longitudinal direction of the rod-shaped segments.

[0135] The embodiments will now be further described with reference to the figures.

[0136] An apparatus 1 according to one embodiment of the invention is shown in Fig. 1. The apparatus 1 comprises a conveyor 2 and an auxiliary conveyor 3. The conveyor 2 comprises a drum 4 adapted to rotate about an axis of rotation 5 extending in a longitudinal direction 100. The auxiliary conveyor 3 comprises a second drum 6 adapted to rotate about a second axis of rotation 7 extending in a longitudinal direction 100. The two drums 4, 6 rotate in different directions. The conveyor 2 is adapted to wind bridging elements 21 (not shown in Fig. 1) around rod-shaped segments 8 to form aerosol-generating articles 9. The conveyor 2, in particular the drum 4, comprises a support surface 10. The support surface 10 is adapted to support and hold the rod-shaped segments 8 and the aerosol-generating articles 9.

[0137] The apparatus 2 further comprises a contact element 11 having a facing surface 12. The facing surface 12 facilitates wrapping a bridging element 21 around the rod-shaped segment 8 to form the aerosol-generating article 9.

[0138] Figure 2 shows a plan view on the support surface 10 of the conveyor 2. The conveyor 2, in particular the drum 4, comprises a number of grooves 13 formed on the support surface 10. The grooves 13 extend mainly in the longitudinal direction 100 and are adapted to receive the rod-shaped segments 8. The grooves 13 are equidistantly spaced around the support surface 10 of the drum 4. Suction holes 14 are provided in the support surface 10 in the region of the grooves 13. Suction holes 14 may also be provided outside the grooves 13, as shown on the right side of Figure 2. The suction holes 14 are adapted to facilitate the retention of the rod-shaped segments 8 and the aerosol-generating articles 9.

[0139] The conveyor 2 further includes storage cavities 15. The storage cavities 15 open into the channels 13 and accommodate the spacers 16. One storage cavity 15 is disposed in each channel 13. Each storage cavity 15 accommodates one spacer 16. The storage cavities 15 are disposed between the suction holes 14 of the channels 13. The spacers 16 can be moved from a stored position in which each spacer 16 is flush with the support surface 10, as shown in the channel 13 on the right side of FIG. 2, to an operating position in which the spacers 16 protrude from the support surface 10, as shown in the channel 13 in the center of FIG. 2.

[0140] In the embodiment shown in Fig. 2, the rod-like segment 8 comprises a first rod-like segment 17 and a second rod-like segment 18. In the operating position, the spacer 16 is disposed between the first rod-like segment 17 and the second rod-like segment 18. On the left side of Fig. 2, the spacer 16 is in a retracted position to establish a gap 19 between the first rod-like segment 17 and the second rod-like segment 18.

[0141] Figures 3 and 4 show how the spacers 16 move from a stored position to an operating position. A number of storage cavities 15 are spaced around the support surface 10 of the drum 4. Each support cavity 15 accommodates a spacer 16. For simplicity, only one spacer 16 is shown in Figures 3 and 4. The conveyor 2 further comprises a cam 20. The cam 20 is stationary while the drum 4 rotates about the axis of rotation 5. Thus, the storage cavities 15 and the spacers 16 rotate around the cam 20.

[0142] In Figure 3, the spacer 16 is in the stored position. When the storage cavity 15 having the spacer 16 is aligned with the cam 20, the spacer 16 contacts the distal end 30 of the cam 20 and is partially pushed out of the storage cavity 15 to the operating position. In the operating position, the spacer 16 protrudes from the support surface 10, as shown in Figure 4.

[0143] FIG. 5 illustrates how the spacer 16 returns to the storage position in accordance with an embodiment of the present invention. The spacer 16 includes two flanges 26 that protrude laterally from the spacer 16. The springs 27 are disposed between the flanges 26 and the support surface 10. The storage cavity 15 in FIG. 5 is larger than the storage cavity 15 in FIGS. 3 and 4 to provide space for the flanges 26 and the springs 27. The springs 27 bias the spacer 16 into the storage cavity 15 toward the storage position, as shown in the upper left portion of FIG. 5. When the spacer 16 moves toward the distal end 30 of the cam 20, the distal end 30 of the cam 20 partially pushes the spacer 16 out of the storage cavity 15 to the operating position against the biasing force of the springs 27. The spacer 16 then protrudes from the support surface 10, as shown in the upper center portion of FIG. 5. As the spacer 16 moves away from the distal end 30 of the cam 20, the distal end 30 is no longer in contact with the spacer 16, so that the spring 27 pushes the spacer 16 back into the receiving recess 15, as shown in the upper right portion of FIG. 5.

[0144] Figures 6-10 show schematic diagrams of how an aerosol-generating article 9 is produced according to one embodiment of the present invention. Figure 6 shows an empty groove 13 on the support surface 10 of the drum 4 of the conveyor 2. The drum 4 and the grooves 13 on the drum 4 extend in a longitudinal direction 100. For illustrative purposes, only one groove 13 is shown in Figure 6. However, the conveyor 2 comprises a plurality of grooves 13. Suction holes 14 are arranged in the grooves 13 and storage cavities 15 are arranged between the suction holes 14. The storage cavities 15 accommodate a spacer 16, which in Figure 6 is in a stored position. A first rod-shaped segment 17 is inserted into the groove 13 as shown in Figure 7. The suction holes 14 serve to hold the first rod-shaped segment 17 in the groove 13. The spacer 16 is then moved to an operating position adjacent to the first rod-shaped segment 17, as shown in Figure 8. Here, the spacer 16 protrudes from the support surface 10. As shown in FIG. 9, the second rod-shaped segment 18 is then inserted into the groove 13 adjacent to the spacer 16. The second rod-shaped segment 18 is inserted into the spacer 16 on the opposite side to the first rod-shaped segment 17. The rod-shaped segments 17, 18 are pressed against the spacer 16, in particular by a plunger 28. In FIG. 9, only one plunger 28 is shown, which presses the second rod-shaped segment 18 against the spacer 16. However, a second plunger may be arranged on the opposite side of the drum 4 to press the first rod-shaped segment 17 against the spacer 16. Instead of or in addition to the plunger 28, a guide surface 29 (not shown in FIG. 9) or air pressure may be used to press the rod-shaped segments 17, 18 against the spacer 16. The spacer 16 is then moved back to the stored position, such that a gap 19 is established between the first rod-shaped segment 17 and the second rod-shaped segment 18, as shown in FIG. 10. Gap 19 has a predetermined width, i.e., the width of spacer 16. First rod-shaped segment 17 and second rod-shaped segment 18 are then wrapped with bridging element 21 to form aerosol-generating article 9. In Figures 6-10, drum 4 remains stationary.However, the drum 4 may also be rotated about an axis of rotation relative to a cam 20 to move the spacer 16 from the retracted position to the operative position, as shown in Figures 3 and 4 .

[0145] A cross-sectional view of an aerosol-generating article 9 manufactured using a method according to one embodiment of the present invention is shown in Figure 11. The aerosol-generating article 9 extends mainly along a longitudinal axis 100 and comprises a first rod-shaped segment 17 and a second rod-shaped segment 18. The first rod-shaped segment 17 is disposed at a distance from the second rod-shaped segment 18 such that a gap 19 of a predetermined width is established between the two rod-shaped segments 17, 18. The aerosol-generating article 9 further comprises a bridging element 21. The bridging element 21 is wrapped around the first rod-shaped segment 17 and the second rod-shaped segment 18 such that the gap 19 is maintained in the aerosol-generating article 9.

[0146] A method for manufacturing an aerosol-generating article 9 according to one embodiment of the present invention is shown in Figure 12. In step i), a rod-shaped material 22 is provided. In step ii), the rod-shaped material 22 is cut into a first rod-shaped segment 17 and a third rod-shaped segment 23. The first rod-shaped segment 17 and the third rod-shaped segment 23 are axially aligned with respect to a longitudinal axis direction 100 and spaced apart from each other. In step iii), a spacer 16 is then disposed adjacent to the first rod-shaped segment 17, and a second spacer 24 is disposed adjacent to the third rod-shaped segment 23. In step iv), a second rod-shaped segment 18 is inserted between the two spacers 16, 24. Thus, the two aligned spacers 16, 24 are alternately disposed with the three aligned rod-shaped segments 17, 18, 23. Pressure may be applied from both sides of the assembly comprising the three rod-shaped segments 17, 18, 23 and the two spacers 16, 24 to place the components adjacent to each other. The pressure may be provided by a stationary guide surface 29, as indicated by the arrows in step iv), engaging with the outer end of the first rod-shaped segment 17 or the third rod-shaped segment 23. The stationary guide surface 29 may extend at least partially along the circumference of the conveyor 2, and the stationary guide surface 29 may be inclined with respect to the longitudinal direction 100. A second stationary guide surface (not shown in FIG. 12) may be arranged on the opposite side of the conveyor 2. As an alternative to the guide surface 29, the force indicated by the arrows in step iv) may be provided by a plunger 28 or plungers 28, as shown in FIG. 9. The plunger 28 or plungers 28 may be stationary or may rotate with the drum 4. In step v), the two spacers 16, 24 are removed so that a gap 19 is established between the first rod-shaped segment 17 and the second rod-shaped segment 18, and a second gap 25 is established between the second rod-shaped segment 18 and the third rod-shaped segment 23.In step vi), a bridging element 21 is attached to the first rod-shaped segment 17, the second rod-shaped segment 18, and the third rod-shaped segment 23 and wrapped around these three rod-shaped segments 17, 18, 23. The bridging element 21 serves to maintain a gap 19 between the first rod-shaped segment 17 and the second rod-shaped segment 18, and a second gap 25 between the second rod-shaped segment 18 and the third rod-shaped segment 23. In step vii), a cut is made through the bridging element 21 and the second rod-shaped segment 18, such that two aerosol-generating articles 9 are formed. The cut is made substantially in the middle of the second rod-shaped segment 18. The aerosol-generating articles 9 extend mainly in a longitudinal direction 100. In step viii), one of the two aerosol-generating articles 9 is rotated 180 degrees, such that the two aerosol-generating articles 9 are oriented in the same direction. The rotation is performed around an axis of rotation perpendicular to the longitudinal direction 100 of the aerosol-generating article 9.
