  Embodiments of the present invention will now be described by way of example only with reference to the accompanying drawings.

FIG. 5 is a side view of aligned rods and chipping paper patches. FIG. 3 is an end view of aligned rods and chipping paper patches all contained in a flute of a rotating drum. It is an end view of a rotating drum. It is a side view of a rotating drum. It is sectional drawing of a rotating drum. It is a perspective view of a suction control member. It is a 1st side view of a suction control member.

  When assembling the smoking article as shown in FIGS. 1a and 1b, the two tobacco rods 1 and the at least one filter rod 2 are aligned. In this aligned arrangement, one or more filter rods 2 are arranged between two tobacco rods 1. They are joined using at least one filter rod 2 and a tipping paper patch 3 wound around a part of each tobacco rod 1. Although FIG. 1 a shows one filter rod 2 disposed between two tobacco rods 1, it will be appreciated that a plurality of filter rods 2 may be included in an aligned rod-shaped article.

  The tipping paper patch 3 is provided by an apparatus that applies an adhesive to one side of the tipping paper web and cuts the web to form the patch 3. Each chipping paper patch 3 is then secured to the aligned rods 1 and 2 in such a manner that the chipping paper patch 3 is positioned over at least a portion of one or more filter rods 2 and each tobacco rod 1. The

  The chipping paper patch 3 has an adhesive applied to one side and one end region of the chipping paper patch 3 so that the chipping paper patch 3 is fixed to the aligned rods 1 and 2 by the adhesive. One end is pressed onto the aligned rods 1 and 2. In this method, when the aligned rods 1 and 2 are rolled, the chipping paper patch 3 is bonded around the circumferences of the rods 1 and 2, and they are joined together so that the ends 2 are connected. Two smoking articles are formed.

  The aligned rods 1 and 2 and the chipping paper patch 3 are rolled by the rotating drum 4 so that the chipping paper patch 3 is wound around the aligned rods 1 and 2.

  FIG. 1 b shows the aligned rods 1, 2 and the chipping paper patch 3 when the chipping paper patch 3 is secured to the aligned rods 1, 2 and then housed in the flute 5 of the rotating drum 4. Is shown. The flute 5 is formed in the peripheral surface 6 of the rotating drum 4 and includes a curved recess for receiving the aligned rods 1 and 2 and the tipping paper patch 3 therein. Although one flute 5 is shown in FIG. 1 b, a plurality of flutes are formed on the peripheral surface 6 of the rotating drum 4. Each flute 5 extends in an axial direction across the circumferential surface 6 so that the rods 1 and 2 aligned in a line move in a direction transverse to the length when the rotating drum 4 rotates.

  As shown, the chipping paper patch 3 and the aligned rods 1 and 2 are secured by partially wrapping the chipping paper patch 3 around the aligned rods 1 and 2. The chipping paper patch 3 extends in the following direction over the peripheral surface 6 of the rotary drum 4. That is, the rotating drum 4 rotates in the direction indicated by the arrow 7, and the chipping paper patch 3 extends in the opposite direction and is dragged behind the rods 1, 2 on which it is aligned.

  As will be described in detail later, when the rotating drum 4 rotates in the direction of arrow 7, the aligned rods 1 and 2 roll out of the flute 5 and roll along the peripheral surface 6 of the rotating drum 4 in the direction of arrow 8. Is done. When the rods 1 and 2 aligned in this manner are rolled, the chipping paper patch 3 is wound around the rods 1 and 2 aligned and they are joined. The packaged assembly can then be contained in another flute upstream of the first flute and transferred to another device.

  FIG. 2 shows a rotating drum assembly of a smoking article assembling apparatus. The rotating drum assembly includes a rotating drum 4 and a roll hand 9. As described with reference to FIG. 1 b, the rotating drum 4 has a peripheral surface 6 with a plurality of flutes 5 for receiving aligned rods 1, 2 to which the chipping paper patch 3 is fixed.

  As the rotating drum 4 rotates in the direction of arrow 7 and the roll hand 9 continues to stand, the rolling action described above with reference to FIG. 1b occurs. That is, the rods 1 and 2 arranged in an aligned manner by the roll hand 9 roll out along the peripheral surface 6 from the flute 5 and enter the upstream flute. Wrapped by 3.

  The rotating drum 4 has a storage position indicated by a straight line 10. When the flute 5 passes through the receiving position 10, the aligned rods 1 and 2 are transferred into the flute 5 together with the chipping paper patch 3. In this example, the aligned rods 1 and 2 and the chipping paper patch 3 can be transferred onto a rotating drum 4 from a supply drum (not shown) located upstream. In another example, tobacco rod 1, at least one filter rod 2 and tipping paper patch 3 may be supplied from different drums (not shown). In any case, the flute 5 of the rotating drum 4 contains two tobacco rods 1, at least one filter rod 2 and a chipping paper patch 3.

  The rods 1 and 2 arranged in an aligned manner are accommodated in the flute 5 by the method described with reference to FIG. 1, that is, by the chipping paper patch 3 following the peripheral surface 6 of the rotating drum 4. As will be described in detail with reference to FIGS. 3a to 4b, the aligned rods 1 and 2 and the tipping paper patch 3 are held in the flute 5 by suction holes.

  As shown in FIG. 2, when the rotary drum 4 rotates, the aligned rods 1 and 2 and the chipping paper patch 3 are conveyed to the roll hand 9. The roll hand 9 includes a leading end 11 that contacts and pushes the aligned rods 1, 2 as the rotating drum 4 rotates and pushes it out of the flute 5. The roll hand 9 includes a rolling surface 12 which is spaced apart from and parallel to the peripheral surface 6 of the rotary drum 4. In other words, the rolling surface 12 has a longer radius than the peripheral surface 6 of the rotating drum 4 and is curved around the rotation axis of the rotating drum 4.

  The aligned rods 1 and 2 are pushed out of the flute 5 and then rolled between the peripheral surface 6 of the dynamic rotating drum 4 and the rolling surface 12 of the static roll hand 9. Due to the contact between the roll hand 9 and the rotating drum 4, the aligned rods 1 and 2 rotate in the opposite direction to the rotating drum 4 and effectively roll in the rearward direction with respect to the peripheral surface 6 of the rotating drum 4. The trailing chip patch 3 is wound around the rods 1 and 2 arranged in an aligned manner.

  Naturally, during this roll action, the aligned rods 1 and 2 move backward relative to the rotating drum 4 while moving forward relative to the stationary roll hand 9. That is, the aligned rods 1 and 2 move in the forward direction at a speed slower than the speed at which the peripheral surface 6 of the rotating drum 4 moves in the forward direction 7.

  When the aligned rods 1 and 2 are pushed out of the flute 5 and disposed between the peripheral surface 6 of the rotating drum 4 and the rolling surface 12 of the roll hand 9, the aligned rods 1 and 2 are The roll hand 9 is positioned relative to the rotating drum 4 so that it is somewhat compressed. By doing so, the chipping paper patch 3 is strongly wound around the aligned rods 1 and 2, and the chipping paper patch 3 and the aligned rods 1 and 2 are sufficiently bonded.

  As shown in FIG. 2, the rods 1 and 2 arranged in alignment are accommodated on the rotating drum 4 in the flute 5 every other rod. For the sake of clarity, the odd-numbered flute is considered as a first group called flute 5a, and the even-numbered flute is considered as a second group called flute 5b. Therefore, the first flute 5 a and the second flute 5 b are alternately arranged around the peripheral surface 6 of the rotating drum 4.

  Upstream of the roll hand 9, the odd-numbered flute 5 a accommodates the rods 1, 2 and the chipping paper patch 3 that are aligned. The even-numbered flutes 5 b are arranged between the odd-numbered flutes 5 a and are empty in front of the roll hand 9. That is, the even-numbered flute 5b does not accommodate the aligned rods 1 and 2 before reaching the roll hand 9.

  In this example, the tipping paper patch 3 is designed to be wound around the aligned rods 1 and 2 at least twice so that the two layers of chipping paper surround the aligned rods 1 and 2. Yes.

  The rolling surface 12 of the roll hand 9 extends from the leading end 11 of the roll hand 9 in the circumferential direction of the rotary drum 4. As shown, the roll hand 9 extends a distance equal to four flutes 5 minutes. In other words, if the interval between two adjacent flutes 5 on the rotating drum 4 is considered as one segment, the roll hand 9 extends a length of three segments around the rotating drum 4.

  Thus, from one odd-numbered flute 5a to which the aligned rods 1 and 2 are rolled, this is rolled beyond the even-numbered flute 5b and beyond the second odd-numbered flute 5a. Further, when the rolled rods 1 and 2 arranged in alignment reach one end of the roll hand 9, they reach the second even-numbered flute 5b. That is, the rods 1 and 2 arranged in an aligned manner from the odd-numbered flute 5a to the even-numbered flute 5b are rolled over the three segments of the rotating drum 4.

  In FIG. 2, the arc length between the flutes 5 on the circumference 6 of the rotating drum 4 corresponds to about 1.5 revolutions of the rods 1 and 2 aligned along the circumference. Thus, when the aligned rods 1 and 2 are rolled over three segments, the aligned rods 1 and 2 are rolled about 4.5 times around their circumference.

  In another embodiment, the arc length is equal to 1 to 3 revolutions of the aligned rods 1 and 2 over its circumference. Therefore, the aligned rods 1, 2 are rolled 3-9 times, preferably at least 3.5 times around their circumference. Of course, the exact number of times the aligned rods 1 and 2 are rolled depends on the diameter of the rods 1 and 2 so that this number varies if the final smoking article is thin or thin.

  By rolling the aligned rods 1 and 2 at least 3 times and at most 9 times their circumference, the chipping paper patch 3 is wound twice on the aligned rods 1 and 2 and completely bonded. I know that.

  As described above, the aligned rods 1 and 2 are accommodated in the odd-numbered flute 5 a together with the chipping paper patch 3 upstream of the roll hand 9. When the rolled and aligned rods 1 and 2 leave the downstream end of the roll hand 9, they are accommodated in the even-numbered flute 5b.

  The rotating drum assembly includes a suction control member 13. The rotating drum 4 rotates with respect to the suction control member 13. While the rotating drum 4 is rotating, the suction control member is configured to suck through the suction holes in the odd-numbered and even-numbered flutes 5 of the rotating drum 4.

  The suction hole of the rotary drum 4 and the suction control member 13 will be described in detail below with reference to FIGS.

  FIG. 3a shows a side view of the rotating drum 4 with the odd-numbered flutes 5a and the even-numbered flutes 5b described with reference to FIG. As shown in FIG. 3a, the odd-numbered flutes 5a each include a pair of first suction holes 14, and the even-numbered flutes 5b each include a pair of second suction holes 15.

  The suction control member is configured such that suction is performed via the first suction hole 14 upstream of the roll hand 9 and suction is not performed via the second suction hole 15.

  The suction control member is configured so that suction is performed via the second suction hole 15 downstream of the roll hand 9 and suction is not performed via the first suction hole 14.

  The first suction holes 14 are arranged as two rows of first suction holes 14 in each odd-numbered flute 5a. These two rows of first suction holes 14 are aligned along the peripheral surface 6 of the rotating drum 4. That is, the first suction holes 14 in each row are located at the same distance from the center line 17 of the peripheral surface 6 of the rotating drum 4.

  The second suction holes 15 are arranged as two rows of second suction holes 15 in each of the even-numbered flutes 5b. These two rows of second suction holes 15 are aligned along the peripheral surface 6 of the rotating drum 4. That is, the second suction holes 15 in each row are located at the same distance from the center line 17 of the peripheral surface 6 of the rotating drum 4.

  The rows of the first and second suction holes 14 and 15 of the rotary drum 4 are separated in the axial direction. Each row of the first suction holes 14 is aligned with a first distance from the center line 17 of the rotating drum 4, and each row of the second suction holes 15 is aligned with the second line from the center line 17 of the rotating drum 4. Aligned at a distance.

  Each flute 5 of the rotating drum 4 also includes a pair of third suction holes 34 as shown in FIG. 3a. These third suction holes 34 are located relatively close to the center line 17 of the rotating drum 4, that is, are arranged between the first and second suction holes 14, 15. The third suction hole 34 is sucked upstream of the roll hand 9 and downstream of the roll hand 9, holds the filter rod 2 member not wrapped upstream of the roll hand 9, and wrapped aligned downstream of the roll hand 9. The filter part of the arranged rods 1 and 2 is held.

  As shown in FIG. 3 b, which is a cross-sectional view taken along the line AA shown in FIG.

  The first, second and third suction holes 14, 15 and 34 extend from the peripheral surface 6 of the rotating drum 4 through the rotating drum 4 to the hole 18. Accordingly, each of the first, second, and third suction holes 14, 15, and 34 has an opening on the peripheral surface 6 of the rotating drum 4, and has an opening on the inner surface 20 of the rotating drum 4.

  FIG. 4 a shows the suction control member 13 configured to be received inside the hole 18 of the rotating drum 4. The suction control member 13 is fitted inside the rotary drum 4, and the rotary drum 4 rotates around the suction control member in a stationary state. The outer surface 21 of the suction control member 13 is in the vicinity of the inner surface 20 of the rotary drum 4. You may prepare the seal which seals the gap | interval between these surfaces.

  The suction control member 13 includes an internal interval 22. This is connected to a suction source such as a vacuum pump for exhausting air from the internal spacing 22 of the suction control member 13.

  As shown in FIG. 4 a, the suction control member 13 includes a plurality of suction channels 23, 24, and 35, which are sucked from the outer surface 21 near the inner surface 20 of the rotating drum 4 through the suction control member 13. It is formed from a passage extending to the internal spacing 22 of the member 13.

  The suction channels 23, 24 are arranged so that when the rotary drum 4 rotates, the first, second and third suction holes 14, 15 move in alignment with and away from the suction channels 23, 24, 35. Has been. Therefore, the configuration of the suction channels 23, 24, and 35 determines the timing of suction through the first, second, and third suction holes 14, 15, and 34 in the rotating drum 4 when the rotating drum 4 rotates. Is done.

  The configuration of the suction channels 23, 24, 35 will be described with reference to FIGS.

  As shown in FIGS. 4 a and 4 b, the suction control member 13 has a first suction channel 23, a second suction channel 24 and a third suction channel 35.

  The first suction channel 23 is formed from openings aligned with the two rows of the first suction holes 14 and the third suction holes 34 of the rotary drum 4. Accordingly, when the rotary drum 4 rotates and passes through the first suction channel 23 of the suction control member 13, suction is performed through the first suction hole 14 and the third suction hole 34. During the rotation, the second suction hole 15 of the rotating drum is aligned with the second suction channel 24, and the second suction channel 24 is positioned so that suction is performed through the second suction hole 15. In order to prevent the first suction channel 23 from performing suction through the second suction hole 15, the two rows of second suction channels 24 are not aligned with the first suction channel 23.

  As shown in FIG. 2, the rotating drum rotates so as to pass through a first region 25 defined between the receiving position 10 and the leading end 11 of the roll hand 9. The first suction channel 23 is arranged so that suction is performed in the first region. Accordingly, suction is performed in the first region 25 through the first suction hole 14, and suction is not performed through the second suction hole 15. That is, suction is performed through the first suction holes 14 in the odd-numbered flutes 5a, but suction is not performed through the second suction holes 15 in the even-numbered flutes 5b.

  As described above, the odd-numbered flute 5a in the first region 25 has the rods 1 and 2 and the tipping paper patch 3 arranged in alignment. Accordingly, the first suction hole 14 functions to hold the rods 1 and 2 aligned in the odd-numbered flute 5 a upstream of the roll hand 9.

  Further, in order to hold the one or more filter rods 2 in each odd-numbered flute 5a to the odd-numbered flute 5a, suction is performed through the third suction hole 34 in the first region 25.

  One end of the first suction channel 23 is aligned with the leading end 11 of the roll hand 9. Therefore, when the aligned rods 1 and 2 reach the starting point of the roll hand 9, the suction for holding the aligned rods 1 and 2 in the odd-numbered flute 5a is released, which is the method described above. It becomes possible to roll off the odd-numbered flute 5a.

  As shown in FIG. 2, the rotary drum 4 rotates so as to pass through the second region 26 corresponding to the length of the roll hand 9. Within this second region 26, the first, second or third of the chipping paper patch 3 is wrapped around the aligned rods 1 and 2 to form the aligned rods 1 and 2 packaged. Suction is not performed through the suction holes 14 and 15, and the aligned rods 1 and 2 roll out from the odd-numbered flute 5 a to the peripheral surface 6 of the rotating drum 4.

  As shown in FIG. 2, the rotating drum 4 rotates so as to pass through the third region 27. In this region, the second suction channel 24 is arranged so as to perform suction through the second suction hole 15. With reference to FIGS. 4 a and 4 b, the second suction channel 24 is formed from a plurality of spaced-apart openings extending around the outer surface 21 of the suction control member 13. Preferably, the second suction channels 24 are not connected across the outer surface 21. However, in another example, the second suction channels 24 are at least partially connected across the outer surface 21.

  These second suction channels 24 are arranged so as to be aligned with the second suction holes 15 in the even-numbered flutes 5 b of the rotating drum 4. On the other hand, the first suction holes 14 in the odd-numbered flutes 5 a of the rotating drum 4 are not aligned with the second suction channels 24, and are instead blocked by the peripheral surface 6 of the suction control member 13. Accordingly, suction is performed through the second suction hole 15 in the even-numbered flute 5b in order to hold the aligned rods 1 and 2 that are rolled downstream of the roll hand 9.

  The third suction channel 35 includes a plurality of openings that extend around the outer surface 21 of the suction control member 13 in the third region 27 and are spaced from each other. The third suction channel is arranged to be aligned with the third suction hole 34. Accordingly, the third suction channel 35 is disposed between the second suction channels 24. Accordingly, downstream of the roll hand 9, the third suction hole 34 operates to hold the filter portion of the wrapped rods 1, 2 arranged in alignment.

  As shown in FIG. 2, the third region 27 extends from one end of the roll hand 9 to the transfer point 28. At the transfer point, aligned rods 1, 2 that are rolled for transfer to another drum or conveyor (not shown) are released from the rotating drum 4.

  As shown in FIG. 4 a, on the upstream side of the first suction channel 23, the suction control member 13 includes a buffer region 29, where the outer surface 21 is low so as not to be near the inner surface 20 of the rotating drum 4. This buffer area 29 is open to the atmosphere or the reservoir. Thanks to this buffer area 29, the air pressure becomes equal and the residual suction or pressurization is dissipated.

  Further, the outer surface 21 of the suction control member 13 in the second region 26 corresponding to the roll hand 9 is made not to be in the vicinity of the inner surface 20 of the rotary drum 4 in order to equalize the pressure by dissipating any remaining reduced pressure. Have This prevents residual suction that adversely affects the rolling process, such as pulling the chipping paper patch 3 during rolling.

  As shown in FIGS. 3 a and 3 b, the peripheral surface 6 of the rotating drum 4 also has a group of tipping paper suction holes 16. These correspond to the position of the chipping paper patch 3 in the first area 25 upstream of the roll hand 9.

  In order that the chipping paper patch 3 covers the chipping paper suction hole 16 upstream of the roll hand 9 in the first region 25, the chipping paper suction holes 16 of the group are arranged on the downstream side of each odd-numbered flute 5a. A plurality of suction holes 16 are disposed.

  As shown in FIG. 3a, the group of chipping paper suction holes 16 may extend over the adjacent even-numbered flutes 5b. For example, a chipping paper patch 3 suitable for wrapping around the aligned rods 1 and 2 twice extends from the aligned rods 1 and 2 in the odd-numbered flute 5a to the adjacent even-numbered flute 5b. Long enough to extend in the following direction. In this case, the third suction hole 34 in the adjacent even-numbered flute 5b may function to hold a part of the chipping paper patch 3.

  The chipping paper suction hole 16 extends from the peripheral surface 6 through the rotary drum 4 to the inner surface 20. The chipping paper suction hole 16 is aligned with the first suction channel 23. Accordingly, when the tipping paper suction hole 16 passes to the first suction channel 23, suction is performed in the first region 25, and the tipping paper patch 3 is pulled against the peripheral surface 6 of the rotating drum 4.

  In the third region 27, downstream of the roll hand 9, the tipping paper suction hole 16 is not aligned with any of the first, second and third suction channels 23, 24, 35, so that suction is not performed. .

  Within the second region 26 corresponding to the roll hand 9, the suction control member 13 is fixed through the chipping paper patch suction hole 16 after the aligned rods 1 and 2 start to be rolled by the roll hand 9. It is comprised so that time suction may be performed. The suction control member 13 sucks the chipping paper patch 3 during the start of the rolling process to control the trailing edge of the chipping paper patch 3.

  As shown in FIG. 4 b, the suction control member 13 includes a tipping paper suction channel 31 that extends from one end of the first suction channel 23 to the rotating second region 26. These chipping paper suction channels 31 are aligned with the chipping paper suction holes 16 of the rotating drum 4.

  Therefore, when the aligned rods 1 and 2 pass through the leading end 11 of the roll hand 9 and enter the second region 26 at the end of the first region 25, the first suction in the odd-numbered flute 5a is performed. Suction through the hole 14 is released. On the other hand, the suction through the chipping paper suction hole 16 is continued for a short time.

  The time during which the tipping paper suction hole 16 is operating in the second region 26 corresponds to 0.5 to 2 rotations of the circumference of the smoking article between the rotating drum 4 and the roll hand 9, preferably 1-2. Corresponds to rotation. More preferably, the tipping paper patch 3 is sucked through the tipping paper suction holes 16 during the first approximately 1.5 revolutions of the circumference of the smoking article. An area 33 displayed in FIG. 2 indicates an area where suction is performed through the tipping paper suction holes 16 at the start of the rolling process. As shown, this region 33 extends slightly longer than one segment of the rotating drum 4.

  Therefore, the suction of the chipping paper patch 3 is maintained during the time when the rolling process starts and the trailing edge of the chipping paper patch 3 is controlled, but is released during the time when the smoking article is freely rolled by the roll hand 9. Is done.

  The chipping paper patch 3 may be curled before being cut and fed onto the rotating drum 4. Thus, the tipping paper patch 3 is aspirated during the beginning of the rolling process to prevent the trailing curl of the trailing edge of the tipping patch 3 from being turned upward by elastic forces, which can adversely affect the rolling process.

  The length of the tipping paper suction channel 31 determines how long the tipping paper suction hole 16 remains active in the second region 26. In this example, the tipping paper suction channel 31 extends a distance substantially corresponding to the distance between the odd-numbered flute 5a and the even-numbered flute 5b on the rotating drum 4. Accordingly, when the aligned rods 1 and 2 reach the roll hand 9 and roll out from the odd-numbered flute 5a onto the peripheral surface 6 of the rotating drum 4, the even-numbered flutes adjacent to each other are aligned. Suction is performed through the chipping paper suction hole 16 until it reaches approximately 5b.

  Further, as shown in FIG. 4 b, the tipping paper suction channel 31 and the recessed area 30 of the suction control member 13 overlap on the outer surface 21 of the suction control member 13. The third suction is intended to dissipate the residual suction or pressure acting on the third suction hole 34 and to release one or more filter rods 2 in the aligned rods 1, 2 for rolling. The channel 32 extends from a recessed region 30 between the channel 32 aligned with the hole 34 and the tipping paper suction channel 31.
