Figure 4b shows a first side view of the adsorption control component.

As shown in Figs. 1A and 1B, during the assembly of the smokable foods, two tobacco rods 1 and one or more filter rods 2 are arranged in a collation. Within the collision, one or more filter rods 2 are disposed between the two tobacco rods 1. This collation is combined using one or more filter rods 2 and a tipping paper patch 3 wrapped around a portion of each tobacco rod 1. It will be appreciated that FIG. 1A shows a single filter rod 2 disposed between two tobacco rods 1, however, however, the collision of the load articles may include several filter rods 2.

The tipping paper patches 3 are provided by an apparatus for applying adhesive to one side of the web of tipping paper and for cutting the web to form the patches 3. Each of the tipping paper patches 3 is then placed on the rods 2 in such a manner that the tipping paper patches 3 are laid over at least a portion of one or more of the filter rods 2 and each of the tobacco rods 1. [ 1, 2).

The tipping paper patch 3 has an adhesive applied to one side and the one end region of the tipping paper patch 3 is pressed on the collision of the rods 1 and 2 so that the tipping paper patch 3 is pressed against the adhesive To the collision of the rods 1, In this way, when the collision of the rods 1, 2 is rolled, the tipping paper patch 3 will be adhered around the circumference of the rods 1, 2 so that the end- lt; / RTI > together to form two to-be-connected to-end smokers. It can then be cut through the center to form the two smokers.

The collating and tipping paper patches 3 of the rods 1 and 2 are rolled by the rolling drum 4 so that the tipping paper patches 3 are wrapped around the collisions of the rods 1,2.

1B shows a schematic view of a tipping paper patch 3 when the tipping paper patch 3 is anchored to the collision of the rods 1 and 2 and then the collation and tipping paper patch of the rods is received in the flute 5 of the rolling drum 4. [ Shows the collating and tipping paper patch 3 of the rods 1, 2. The flute 5 is formed at the peripheral surface 6 of the rolling drum 4 and is provided with a curved concave in which the collation of the rods 1 and 2 and the tipping paper patch 3 are received recess. A plurality of flutes are formed around the outer circumferential surface 6 of the rolling drum 4, although a single flute 5 is shown in Fig. Each of the flutes 5 extends axially over the outer circumferential surface 6 so that as the rolling drum 4 rotates the collisions of the rods 1 and 2 move transversely with respect to their length do.

As shown, the anchorage between the tipping paper patches 3 and the collisions of the rods 1, 2 is a part of the tipping paper patch 3 around the collisions of the rods 1, Lt; / RTI > The tipping paper patches 3 extend above the outer circumferential surface 6 of the rolling drum 4 in the trailing direction. That is to say that the rolling drum 4 rotates in the direction indicated by the arrow 7 and the tipping paper patch 3 extends in the opposite direction which leads to the trailing of the rolls 1, (Trail).

As will be described in greater detail below, when the rolling drum 4 rotates in the direction of the arrow 7, the collisions of the rods 1, 2 are out of the flutes 5 in the direction of arrow 8 Rolling along the outer circumferential surface 6 of the rolling drum 4 is induced. When the collation of the rods 1, 2 is rolled in such a way that the tipping paper patch 3 is wrapped around the collision of the rods 1, 2, thereby thereby coupling the rods together. The wrapped collision can then be received in another flute, which was previously upstream of the initial flute, and can be delivered to an additional device.

Figure 2 shows a rolling drum assembly of a device for assembling smoking articles. The rolling drum assembly includes a rolling drum (4) and a roll hand (9). The rolling drum 4 is provided with a plurality of rollers 1 and 2 for receiving the collisions of the rods 1 and 2 with the tipping paper patches 3 anchored to the coils of the rods, (6) having flutes (5).

The rolling drum 4 is rotated in the direction of the arrow 7 and the roll hand 9 is held statically to induce the rolling action previously described with reference to Fig. That is to say that the roll hand 9 causes the collisions of the rods 1 and 2 to roll out of the flute 5 and into the flutes upstream and along the outer circumferential surface 6, 3 to wrap the collisions of the rods 1,2.

The rolling drum (4) has a receiving position indicated by a line (10). When the flute 5 passes this receiving position 10 the collisions of the rods 1 and 2 are transferred into such a flute 5 together with the tipping paper patch 3. In this example, the collating and tipping paper patches 3 of the rods 1, 2 can be transferred from the upstream feed drum (not shown) to the rolling drum 4. In other examples, the tobacco rods 1, the at least one filter rod 2, and the tipping paper patch 3 may be supplied by different drums (not shown). Nevertheless, the flute 5 of the rolling drum 4 accommodates two tobacco rods 1, one or more filter rods 2 and a tipping paper patch 3.

The collation of the rods 1 and 2 is accommodated in the flute 5 in the manner described with reference to Figure 1b i.e. the tipping paper patch 3 is then placed on the outer peripheral surface of the rolling drum 4 6) Trail above. The collation and tipping paper patches 3 of the rods 1 and 2 are retained in the flutes 5 by the suction holes as described in more detail with reference to Figures 3a to 4b. .

2, when the rolling drum 4 rotates, the collision and tipping paper patches 3 of the rods 1 and 2 are conveyed to the roll hand 9. The roll hand 9 contacts the collision of the rods 1 and 2 and when the rolling drum 4 rotates it has a leading edge pushing the collisions of these rods out of the flute 5, (11). The roll hand 9 also includes a rolling surface 12 parallel to and spaced from the outer circumferential surface 6 of the rolling drum 4. In other words, the rolling surface 12 having a larger radius than the outer circumferential surface 6 of the rolling drum 4 is curved and centered on the rotation axis of the rolling drum 4 ).

After the collisions of the rods 1 and 2 are pushed out of the flute 5 the collision of these rods causes the moving outer circumferential surface 6 of the rolling drum 4 and the static rolling surface 12 of the roll hand 9 Lt; / RTI > Due to the contact with the roll hand 9 and the rolling drum 4 the collision of the rods 1 and 2 will rotate in the opposite direction to the rolling drum 4 and the outer peripheral surface of the rolling drum 4 So that the trailing tipping paper patch 3 is wrapped around the collision of the rods 1, 2.

It will be appreciated that during this rolling operation, the collisions of the rods 1, 2 will move in the backward direction relative to the rolling drum 4 while moving in the forward direction relative to the static roll hand 9. That is, the collision of the rods 1, 2 will move forward at a speed slower than the speed at which the outer circumferential surface 6 of the rolling drum 4 moves in the forward direction 7.

The roll hand 9 is positioned relative to the rolling drum 4 so that once the collisions of the rods 1 and 2 are pushed out of the flute 5 and the outer peripheral surface 6 of the rolling drum 4 and the roll hand 4, The rolling of the rods 1, 2 is slightly compressed. This is because the tipping paper patch 3 is tightly wrapped around the collision of the rods 1, 2 to facilitate sufficient adhesion between the tipping paper patch 3 and the collisions of the rods 1, 2 .

As shown in FIG. 2, the collisions of the rods 1, 2 are accommodated on the rolling drums 4 of all the different flutes 5. For the sake of clarity, the odd flutes will be considered as the first group of flutes 5a, and the even flutes will be considered as the second group of flutes 5b. The first flute 5a and the second flutes 5b are thus alternately arranged around the outer circumferential surface 6 of the rolling drum 4.

On the upstream side of the roll hand 9, an odd number of flutes 5a accommodate the collating and tipping paper patches 3 of the rods 2. The even flutes 5b disposed between the odd-numbered flutes 5a are empty before the roll hands 9. [ That is, the even flutes 5b do not accept the collision of the rods 1, 2 before reaching the roll hand 9.

In this example, the tipping paper patches 3 are designed to be wrapped at least twice around the collision of the rods 1, 2 such that the two layers of the tipping paper collapse the rods 1, Circumscribe.

The rolling surface 12 of the roll hand 9 extends from the leading edge 11 of the roll hand 9 in the direction of the circumference of the rolling drum 4. As shown, the roll hand 9 extends an equal distance relative to the four flutes 5. In other words, if the space between two adjacent flutes 5 on the rolling drum 4 is considered as one segment, the roll hand 9 extends by the length of the three segments around the rolling drum 4.

When the collisions of the rods 1 and 2 are rolled, therefore, the collisions of these rods pass from the odd-numbered flutes 5a through the even-numbered flutes 5b to the second odd-numbered flutes 5a And when the rolled collision of the rods 1, 2 reaches the end of the roll hand 9, it will reach the second even-numbered flute 5b. That is, the collisions of the rods 1,2 are rolled over the three segments of the rolling drum 4 from the odd-numbered flutes 5a to the even-numbered flutes 5b.

In Figure 2 the arc length between each flute 5 on the outer circumferential surface 6 of the rolling drum 4 is approximately 1.5 turns of the collation of the rods 1,2 on its circumference ≪ / RTI > Thus, when the collision of the rods 1,2 is rolled over three segments, the collision of the rods 1,2 will be rolled about 4.5 times its circumference.

In other embodiments, the arc length may equate to one to three rotations of the collation of the rods 1,2 on its circumference. Thus, the collisions of the rods 1, 2 can be rolled by 3 to 9 times, preferably by at least 3.5 times, with respect to the circumference thereof. The exact number of times the collisions of the rods 1 and 2 are rolled will depend on the diameter of the rods 1 and 2 so that the eventual smokers are thinner or thicker It will be understood that the number will vary.

By rolling the collisions of the load articles 1, 2 to at least 3 and 9 times for their circumferential portions, the tipping paper patch 3 is wrapped twice around the collision of the rods 1, 2 And found to be thoroughly adhered.

As described above, in the upstream of the roll hand 9, the collision of the rods 1, 2 together with the tipping paper patch 3 is accommodated in the odd-numbered flutes 5a. When the rolled collision of the rods 1, 2 leaves the downstream end of the roll hand 9, the rolled collation of these rods is accommodated in the even number of flutes 5b.

The rolling drum assembly also includes an adsorption control component (13). The rolling drum 4 rotates with respect to the adsorption control component 13. The adsorption control component is configured to supply adsorption to the adsorption holes in the odd and even flutes 5 of the rolling drum 4 during rotation of the rolling drum 4. [

The adsorption holes of the adsorption control component 13 and the rolling drum 4 are described in more detail below with reference to FIGS. 3A to 4B.

Fig. 3A shows a side view of a rolling drum 4 having an odd number of flutes 5a and an even number of flutes 5b, as described with reference to Fig. 3A, each of the odd-numbered flutes 5a includes a pair of first adsorption holes 14, and each of the even-numbered flutes 5b includes a pair of second adsorption holes 15, .

The adsorption control component is configured such that, upstream of the roll hand 9, the adsorption control component 13 applies adsorption to the first adsorption holes 14 and not to the second adsorption holes 15. [

The adsorption control component is configured such that, downstream of the roll hand 9, the adsorption control component 13 applies adsorption to the second adsorption holes 15 and not to the first adsorption holes 14.

The first adsorption holes 14 are arranged in two rows of the first adsorption holes 14 and the two adsorption holes 14 are arranged in each odd number of flutes 5a. These rows of first adsorption holes 14 are aligned along the outer circumferential surface 6 of the rolling drum 4. That is, each row of the first adsorption holes 14 is positioned at the same distance from the center line 17 of the outer peripheral surface 6 of the rolling drum 4.

The second adsorption holes 15 are arranged in two rows of the second adsorption holes 15 and the two adsorption holes 15 are arranged in each even number of flutes 5b. These rows of second adsorption holes 15 are aligned along the outer circumferential surface 6 of the rolling drum 4. That is, each row of the second adsorption holes 15 is positioned at the same distance from the center line 17 of the outer circumferential surface 6 of the rolling drum 4.

The rows of the first and second adsorption holes 14 and 15 in the rolling drum 4 are separated axially. Each row of the first adsorption holes 14 is aligned by a first distance from the center line 17 of the rolling drum 4 while each row of the second adsorption holes 15 is aligned with the center of the rolling drum 4 And aligned by a second distance from the centerline 17.

As shown in FIG. 3A, each of the flutes 5 of the rolling drum 4 also includes a pair of third adsorption holes 34. As shown in FIG. These third adsorption holes 34 are positioned closer to the center line 17 of the rolling drum 4, that is, these holes are disposed between the first or second adsorption holes 14 and 15. The third adsorption holes 34 are provided with adsorption upstream of the roll hand 9 and downstream of the roll hand 9 so that unwrapped filter rod 2 components upstream of the roll hand 9, And retains the filter portion of the wrapped collation of the rods 1, 2 downstream of the roll hand 9.

The rolling drum 4 is formed into a cylinder having a bore 18 extending through the rolling drum 4, as shown in Figure 3B, which is a cross-sectional view taken through line AA shown in Figure 3a. do.

The first, second and third adsorption holes 14,15,34 extend from the outer circumferential surface 6 of the rolling drum 4 through the rolling drum 4 and into the bore 18. Each of the first, second and third adsorption holes 14,15 and 34 therefore has an opening on the outer circumferential surface 6 of the rolling drum 4 and on the inner surface 20 of the rolling drum 4 Respectively.

Figure 4a shows an adsorption control component 13 configured to be received within the bore 18 of the rolling drum 4. [ The adsorption control component 13 fits into the rolling drum 4 and the rolling drum 4 rotates around the static adsorption control component 13. [ The outer surface 21 of the adsorption control component 13 is in close proximity to the inner surface 20 of the rolling drum 4 and a seal is formed between any gap to seal the gap.

The adsorption control component 13 also includes an interior space 22 which is connected to a suction source such as a vacuum pump so that air is introduced into the adsorption control component 13 Evacuated from the interior space 22.

4A, the adsorption control component 13 is connected to the inner space 22 (to which adsorption is supplied) of the adsorption control component 13 from the outer surface 21 via the adsorption control component 13, 24, 35 (which is immediately adjacent to the inner surface 20 of the rolling drum 4), which are formed by passages extending from the inner surface 20 of the rolling drum 4 to the inner surface 20 of the rolling drum 4.

The adsorption channels 23 and 24 are arranged such that when the rolling drum 4 rotates the first, second and third adsorption holes 14 and 15 move into the alignment with the adsorption channels 23, 24 and 35 And moved out of alignment. Thus, the configuration of the adsorption channels 23, 24, 35 is such that when the rolling drum 4 rotates, the adsorption takes place in the first, second and third adsorption holes 14, 15, 34 ) Is determined.

The configuration of the adsorption channels 23, 24, and 35 will be described with reference to Figs. 2 to 4B.

4A and 4B, the adsorption control component 13 has a first adsorption channel 23, second adsorption channels 24, and third adsorption channels 35. The first adsorption channel 23, the second adsorption channels 24,

The first adsorption channel 23 is formed in the rolling drum 4 as an opening aligning with the two rows of the first adsorption holes 14 and the third adsorption holes 34. Therefore, when the rolling drum 4 rotates, the first adsorption holes 14 and the third adsorption holes 34 are connected to the first adsorption channel 23 when they pass over the first adsorption channel 23 at the adsorption control component 13, Will be provided. The second adsorption channels 24 are positioned such that the second adsorption holes 15 in the rolling drum align with the second adsorption channels 24 during rotation and thereby provide adsorption to the second adsorption holes 15 do. The two rows of the second adsorption channels 24 are not aligned with the first adsorption channel 23 so that the first adsorption channel 23 does not provide adsorption to the second adsorption hole 15. [

2, the rolling drum rotates through a first zone 25 defined between the receiving position 10 and the leading edge 11 of the roll hand 9. The first adsorption channel (23) is arranged to provide adsorption in this first zone. Thus, in this first zone 25, the adsorption is applied to the first adsorption holes 14 and not to the second adsorption holes 15. That is, the adsorption is applied to the first adsorption holes 14 in the odd number of flutes 5a, but not to the second adsorption holes 15 in the even number of flutes 5b.

As previously described, in the first zone 25, the odd number of flutes 5a are provided with a collision of the rods 1, 2 as well as the tipping paper patch 3. Thus, the first adsorption holes 14 serve to retain the collisions of the rods 1, 2 in the odd number of flutes 5a upstream of the roll hand 9.

Also in the first zone 25 the adsorption is applied to the third adsorption holes 34 so that one or more filter rods 2 in each odd number of flutes 5a are filled with an odd number of flutes 5a Lt; / RTI >

The end of the first adsorption channel (23) is aligned with the leading edge (11) of the roll hand (9). Thus, when the collision of the rods 1, 2 reaches the beginning of the roll hand 9, the adsorption to retain the rods in the odd number of flutes 5a is released, It is possible to roll out the odd-numbered flutes 5a in the manner described above.

2, the rolling drum 4 also rotates through a second zone 26 corresponding to the length of the roll hand 9. In this second zone 26 the adsorption is not applied to the first, second or third adsorption holes 14,15 and the collisions of the rods 1,2 are applied to the odd number of flutes 5a, Rolling the treaded paper patches 3 onto the outer circumferential surface 6 of the rolling drum 4 so that the tipping paper patches 3 are in contact with the rolls 1 and 2 to form the wrapped collisions of the load articles 1, Wrapped around the collision.

As shown in FIG. 2, the rolling drum also rotates through the third zone 27. The second adsorption channels 24 are arranged to provide adsorption to the second adsorption holes 15 in this zone. 4A and 4B, the second adsorption channels 24 are formed with spaced apart openings extending around the outer surface 21 of the adsorption control component 13. Preferably, the second adsorption channels 24 are not joined together over the outer surface 21. However, in other instances, the second adsorption channels 24 may be at least partially connected across the outer surface 21.

These second adsorption channels 24 are arranged to align with the second adsorption holes 15 in the even flutes 5b of the rolling drum 4. [ On the other hand, the first adsorption holes 14 in the odd number of flutes 5a of the rolling drum 4 are not aligned with the second adsorption channels 24 and, instead, (Closed off) by the outer circumferential surface 6 of the housing. Thus, in the downstream of the roll hand 9, in the second adsorption holes 15 of the even flutes 5b, adsorption is provided to retain the rolled collisions of the load articles 1, do.

The third adsorption channels 35 also include spaced openings extending around the outer surface 21 of the adsorption control component 13 in the third zone 27. The third adsorption channels are arranged to align with the third adsorption holes (34). Thus, the third adsorption channels 35 are arranged between the second adsorption channels 24. Thus, downstream of the roll hand 9, the third adsorption holes 34 are activated to retain the filter portion of the wrapped collision of the load articles 1, 2.

As shown in Figure 2, the third zone 27 is adapted to receive, from the end of the roll hand 9, rolled collisions of the load articles 1, 2 from the rolling drum 4, To a transfer point 28 that is discharged to a conveyor (not shown).

4A, on the upstream side of the first adsorption channel 23, the adsorption control component 13 includes a relief area 29, wherein the outer surface 21 has an outer surface Is not brought close to the inner surface (20) of the rolling drum (4). This abatement area 29 is open to the atmosphere or reservoir. This abatement area 29 allows the pressure to equalize, so that any residual adsorption or increased pressure is diverted.

In addition, within the second zone 26 corresponding to the roll hand 9, the outer surface 21 of the adsorption control component 13 has a concave (not shown) surface which is not directly adjacent to the inner surface 20 of the rolling drum 4 It may have a recessed area 30 so that the pressure can be equalized by allowing any low residual pressure to emanate. This prevents residual adsorption which affects the rolling process, for example by pulling the tipping paper patch 3 during rolling.

As shown in Figs. 3A and 3B, the outer peripheral surface 6 of the rolling drum 4 also has groups of tipping paper adsorption holes 16. These correspond to the position of the tipping paper patch 3 in the first zone 25 upstream of the roll hand 9.

Each of the groups of the tipping paper adsorption holes 16 includes a plurality of suction holes 16 arranged in an array on the downstream side of each odd number of flutes 5a so that the tipping paper patches 3, Covers the tipping paper adsorption holes (16) upstream of the roll hand (9) in the first zone (25).

As shown in FIG. 3A, the group of the tipping paper adsorption holes 16 can extend over the adjacent even-numbered flutes 5b. For example, a tipping paper patch 3 suitable for wrapping twice around the collision of the rods 1, 2 can be applied to the trailing direction from the collision of the rods 1, 2 in the odd-numbered flutes 5a So that it extends over the adjacent even flutes 5b. In this case, the third adsorption holes 34 of the adjacent even-numbered flutes 5b may serve to retain a portion of the tipping paper patch 3.

The tipping paper adsorption holes 16 extend from the outer circumferential surface 6 of the inner surface 20 through the rolling drum 4. The tipping paper adsorption holes (16) are aligned with the first adsorption channel (23). Thus, when the tipping paper adsorption holes 16 pass through the first adsorption channel 23 in the first zone 25, the holes are provided with adsorption and the tipping paper patch 3 is fed to the rolling drum < RTI ID = 0.0 > (6) of the outer tube (4).

In the third zone 27 the tipping paper adsorption holes 16 are not aligned with any of the first, second or third adsorption channels 23, 24, 35 downstream of the roll hand 9, Adsorption is not provided in these holes.

In the second zone 26 corresponding to the roll hand 9 the adsorption control component 13 determines the time after each roll of the rolls 1 and 2 begins to be rolled by the roll hand 9 While applying adsorption to the tipping paper adsorption holes 16. The adsorption control component 13 applies adsorption to the tipping paper patch 3 during the beginning of the rolling process, so that the trailing edge of the tipping paper patch 3 is controlled.

As shown in FIG. 4B, the adsorption control component 13 includes tipping paper adsorption channels 31 extending from the end of the first adsorption channel 23 to the second rotation zone 26. These tipping paper adsorption channels (31) are aligned with the tipping paper adsorption holes (16) in the rolling drum (4).

Thus, at the end of the first zone 25, when the collisions of the rods 1, 2 pass through the leading edge 11 of the roll hand 9 and into the second zone 26, The adsorption provided in the first adsorption holes 14 in the tipping paper adsorption holes 16 is inactivated while the adsorption provided in the tipping paper adsorption holes 16 is maintained in the activated state for a short time.

The time during which the tipping paper adsorption holes 16 are maintained in the activated state in the second zone 26 is between 0.5 and 2 hours of smoking on the circumference of the smoky between the rolling drum 4 and the roll hand 9 Corresponds to one to two turns of the smoker on the rotations, preferably on the circumference of the smoker. More preferably, the adsorption is applied to the tipping paper patch 3 through the tipping paper adsorption holes 16 during approximately the first 1.5 revolutions of the odor on the circumference of the smoking article. The zone 33 shown in Fig. 2 shows the zone where the adsorption is provided to the tipping paper adsorption holes 16 at the beginning of the rolling process. As shown, this zone 33 extends over slightly more than one segment of the rolling drum 4.

Therefore, the adsorption applied to the tipping paper patch 3 is maintained for a time for controlling the trailing edge of the tipping paper patch 3 when the rolling process is started, but the smell is retained by the roll hand 9 It is deactivated at a time that allows it to be rolled freely.

The tipping paper patches 3 may be cut on the rolling drum 4 and curled before being conveyed. Thus, the adsorption is provided to the tipping paper patch 3 during the beginning of the rolling process to prevent the trailing edge of the tipping paper patches 3 from being resiliently curled upward, which affects the rolling process .

The length of the tipping paper adsorption channels 31 will determine the time for the tipping paper adsorption holes 16 to remain active in the second zone 26. In this example, the tipping paper adsorption channels 31 extend over a distance approximately corresponding to the distance between an odd number of flutes 5a and an even number of flats 5b of the rolling drum 4. [ Thus, when the collisions of the rods 1, 2 reach the roll hand 9 and roll out of the odd number of flutes 5a on the outer circumferential surface 6 of the rolling drum 4, Is provided in the tipping paper adsorption holes 16 until the collisions of the rods 1 and 2 reach the adjacent even flute 5b.

4b, the recessed areas 30 of the adsorption control component 13 and the tipping paper adsorption channels 31 are superimposed on the outer surface 21 of the adsorption control component 13. As shown in FIG. The channels 32 extend from the recessed area 30 to between the tipping paper adsorption channels 31 and these channels 32 are aligned with the third adsorption holes 34 to form the third adsorption holes 34, And the one or more filter rods 2 in the collision of the rods 1, 2 are released for rolling.
