Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filter rod manufacturing machine for manufacturing a filter of a cigarette with a filter.

[0002]

2. Description of the Related Art Some cigarettes with a filter are made by adding flavors such as fluff to the cuts of the cigarettes so that the flavors of the cigarettes are varied. However, this type of scented cigarette with a filter is exposed to the outside air once the package is opened. Therefore, if the elapsed time after opening is long, the scent escapes and remains constant. It will be difficult to maintain the taste of.

Further, since this kind of fragrance is added to the cuts of the cigarette itself, the taste cannot be changed depending on the mood. For these reasons, in recent years, rather than adding a flavor to the shreds of cigarettes, it was provided in the filter to allow the user to choose whether or not to taste the flavor when smoking. It is desired to develop a cigarette with a filter capable of obtaining the taste.

This type of cigarette with a filter can be realized by preparing fragrance beads that are crushed to give off a fragrance, and storing the fragrance beads in the filter. More specifically, if the filter is a so-called triple filter, the fragrance beads may be housed in the central void of the triple filter in place of the particles of activated carbon. Even for a filter, there is a possibility that a filter rod manufacturing machine similar to the case of a normal triple filter can be used for manufacturing the filter.

That is, in a normal filter rod manufacturing machine, in the process of transporting the wrapping paper along the wrapping paper transport path, the filter plugs are fed on the wrapping paper at regular intervals, while the filter plugs are fed between the filter plugs. Activated carbon particles are supplied, and then these are wrapped with a wrapping paper to form a filter rod. The individual filters can be obtained by cutting the filter rod into a predetermined length.

[0006]

By the way, in the above-mentioned filter rod manufacturing machine, if the supplying means for supplying the particles of the activated carbon is used as it is and the fragrance beads are handled by this supplying means, the fragrance beads are filtered. It may be damaged or damaged at the stage before the supply between the plugs, which will reduce the yield of the filter.

Further, as the speed of the filter rod manufacturing machine increases, the higher the speed of manufacturing the filter rod, that is, the speed of transporting the wrapping paper, the higher the speed of supplying the fragrance beads between the filter plugs must be. However, in this case, if an attempt is made to increase the supply speed, the force applied to the fragrance beads also increases, and the above-mentioned problems increase.

In this respect, it is sufficient to make the fragrance beads hard,
If it is made too hard, the fragrance beads may be crushed by simply pinching the fragrance beads from the outside of the filter with fingers when smoking. The present invention has been made based on the above-mentioned circumstances, and an object thereof is to cope with speeding up, to reliably supply the fragrance beads between the filter plugs without damaging them, and to stabilize the filter rod. It is to provide a filter rod manufacturing machine that can be molded.

[0009]

The filter rod manufacturing machine according to the present invention is roughly divided into a wrapping paper conveying path for conveying wrapping paper, and a filter plug which is continuously fed on the wrapping paper in the wrapping paper conveying path with a gap. Alternately on the wrapping paper, a plug feeding means for supplying and a bead supplying means for supplying one by one a fragrance bead that is crushed and emits a fragrance when the filter plug is conveyed together with the wrapping paper. The filter plug and the fragrance beads arranged in line are wrapped with a wrapping paper as they are conveyed, and a winding means for continuously forming a filter rod.

The bead supplying means is disposed above the paper web transporting path and sends out the fragrance beads one by one, a receiving port which periodically coincides with the delivery port of the hopper, and a paper web transporting device. The discharge port that moves together and sequentially matches the interval between the filter plugs, and the receiving port and the discharging port are connected to each other, and one fragrance bead received from the receiving port is guided and guided, and the paper is wound from the discharging port. And a connection path for supplying between the upper filter plugs, and a relative speed of the receiving port with respect to the sending port is reduced as compared with a moving speed of the discharging port.

[0011]

According to the above-described filter rod manufacturing machine, when the receiving port of the connection path matches the outlet of the hopper, one fragrance bead is introduced into the connection path through the receiving port.
The fragrance beads are guided in the connection path toward the discharge port. When the discharge port of the connection path matches the space between the filter plugs on the paper wrapper, the fragrance beads are supplied from the discharge port to the space between the filter plugs.

A large number of take-out grooves (not shown) are provided on the outer peripheral surfaces of the take-out drums 8 and 10, and these take-out grooves are formed at equal intervals in the circumferential direction of the take-out drum. The outer peripheral surface of each take-up drum faces the plug hoppers 4, 6 such that a part thereof constitutes the bottom surface of the plug hoppers 4, 6, and therefore the take-out drums 8, 10 facing the plug hoppers 4, 6 are taken. The filter plugs are received in the take-out grooves one by one, and the filter plugs are conveyed downward together with the take-out grooves as the take-out drum rotates.

Further, as shown in FIG. 1, the left half peripheral surface of the take-out drum is covered with a guide (not shown), and this guide prevents the filter plug from falling out of the take-out groove. Then, the plug transport path 12 is provided on the right side of the base 2.
1, the plug conveying path 12 is located on the front side of the take-out drums 4 and 6 in FIG. 1, and extends from one plug hopper 4 side to the other plug hopper 6 side. The plug carrying path 12 is composed of a suction belt conveyor, and the carrying belt is wound around a driving roller 14 and a driven roller 16.

The plug conveying path 12 and the respective take-out drums are connected via lead-out guide paths 18, 20 shown by the one-dot chain line in FIG. 2, and as the take-out drums 8, 10 rotate. The conveyed filter plug is discharged from the take-out groove to the corresponding lead-out guide path, and then supplied from the lead-out guide path onto the plug carrying path 12.

Although the detailed structure of the guide paths 18 and 20 will not be described in detail, each guide path extends directly below the corresponding take-out drum, and the guide paths of the guide paths. A chain conveyor is arranged on the lower side. Pushers are attached to the chain conveyor at a predetermined interval, and the pushers sequentially move into the guide route and are movable along the guide route as the chain conveyor travels. ing.

Therefore, when the chain conveyor travels along with the rotation of the take-out drum, the pusher pushes out the filter plug in the take-out groove that has reached the lowest position and discharges it onto the guide passage, and then the filter plug. Is delivered toward the plug transport path 12 by the pusher. Here, the downstream portion of each lead-out guide path is a direction-changing portion that is curved in an arc shape, and when passing through this direction-changing portion, the axis of the filter plug is aligned with the plug transport path 12 in the longitudinal direction. And is supplied onto the plug transport path 12.

Therefore, as schematically shown in FIG. 2, the charcoal filter plug CF and the plain filter plug PF are sequentially directed to the plug conveying path 12 from the plug hoppers 4, 6 side, that is, from the take-out drum. A flow of the filter plugs CF, PF that is supplied and is separated from each other and is alternately arranged in a row is formed on the plug transport path 12.

A wrapping paper carrying path 22 extends from the end of the plug carrying path 12, and a spacer drum 24 as a space regulating means is arranged at the end of the plug carrying path 12. The spacer drum 24 rotates so that its outer peripheral surface is in contact with the plug transport path 12, and a plurality of protrusions are spirally formed on the outer peripheral surface.

The spacer drum 24 is a filter plug C.
The protrusions are rotated between F and PF so that the protrusions are inserted into each other, and a certain distance is secured between the filter plugs CF and PF by the protrusions, and then the filter plugs are sent out. . Paper transport path 22
Extends from the plug transport path 12 toward the left end of the base 2, and a wrapping paper P is supplied to the start end of the wrapping paper transport 22. Therefore, the charcoal filter plug CF and the plain filter plug PF that have passed through the spacer drum 24 of the plug transport path 12 are sequentially fed onto the wrapping paper P of the wrapping paper transport path 22 at the above-mentioned fixed intervals. .

The wrapping paper P is guided from the wrapping paper roll R through the guide rollers 26 onto the wrapping paper transport path 22 and is guided along the wrapping paper transport path 22. The wrapping paper roll R is rotatably attached to the lower part of the front surface of the base 2 as seen in FIG. The endless garniture tape G running under the wrapping paper P is further provided on the wrapping paper transport path 22.

As the garniture tape G runs, the wrapping paper P
Is fed from the wrapping paper roll R while being wound on the wrapping paper conveying path 22
It travels on the upper side at a constant transport speed, and as a result, the filter plugs CF and PF are also transported while maintaining the above interval. A gluing device 36 is arranged between the wrapping paper roll R and the above-mentioned guide roller 26, and the gluing device 36 is hot with a predetermined width on one side edge thereof as the wrapping paper P travels. An adhesive made of melt resin is applied.

On the other hand, although not shown, the upper surface of the wrapping paper transport path 22 is formed as a lower molding surface for bending the traveling wrapping paper P together with the garniture tape G into a U-shape, and this molding guide surface. An upper molding guide 38, a heater 40, and a cooler 42 are sequentially arranged immediately above from the upstream side. In the paper transport path 22,
A supply device 44 for perfume beads, which will be described later, is arranged on the upstream side of the upper molding guide 38.
As shown in FIG. 3, the perfume beads B can be supplied one by one from a pair of supply positions located above the wrapping paper transport path 22 to the space between the filter plugs CF and PF passing therebelow. Has become. Here, of the pair of supply positions, the fragrance beads B are supplied from the upstream supply position at an interval immediately after the charcoal filter plug CF passes, while the plain filter plug PF is supplied from the downstream supply position. The fragrance beads B are supplied at intervals immediately after the passage.

That is, from each supply position, the same pitch P
The fragrance beads B are supplied at intervals having T, and
One perfume bead B is supplied to each of the intervals between the filter plugs CF and PF that have passed through the supply device 44. Here, the fragrance beads B are formed by dropping a paste-like liquid containing a fragrance such as mackerel into a curable liquid to form a sphere, which is then wrapped in a film made of the curable liquid and dried. Therefore, the fragrance bead B emits a fragrance only after the coating is crushed.

The above-mentioned upper molding guide 38, of the side edges of the wrapping paper P which has already been formed into a U-shape as the wrapping paper P travels, first, one side edge which has not been glued together with the garniture tape G and the filter plug CF. , PF is curved along the outer circumferential surface of the PF, and then the other side edge to which the glue is applied is similarly curved into an arc shape, and this is overlapped on one side edge. .

Therefore, when the wrapping paper P passes through the upper molding guide 38, the wrapping paper P is filtered by the filter plugs CF and PF.
And the fragrance beads B are continuously wrapped, whereby a filter rod is molded. After that, when the filter rod passes through the heater 40 and the cooler 42, the pasting surface of the wrapping paper P is heated and cooled, so that the wrapping paper P is cooled.
Both side edges are bonded to each other to complete the filter rod FR as shown in FIG.

The filter rod F completed in this way
The R is immediately supplied to the cutting portion 46 located downstream of the paper transport path 22, and is formed into the filter rod material RM having a predetermined length at the cutting portion 46. The mechanism and means used for forming the filter rod FR on the above-described paper winding passage 22 are the same as those of the hoisting machine for forming a cigarette.

As shown in FIG. 5, the filter rod material RM has charcoal filter plugs CF at both ends thereof.
Half of these are left, and two plain filter plugs PF and one charcoal filter plug CF are provided in the center, and a total of four fragrance beads B are provided between them.

These bead distributing units 88 and 90 are separated from each other along the above-described wrapping paper carrying path 22, and the structure of one of the bead distributing units 88 located on the upstream side is shown in FIGS. 8 and 9.
Is shown in.

The bead distributing unit 88 is provided with a vertically extending support rod 92, and the lower end of this support rod 92 is fixed to the base 2 side although not shown. A rectangular connector 94 is fixedly attached to the upper end of the support rod 92. That is, the connector 94 is attached to one end of the support rod 92 by penetrating the upper end of the support rod 92, and the other end of the connector 94 is horizontally projected toward the above-described paper web transport path 22. A connector hole 96 penetrating in the vertical direction is formed in the connector 94 between the other end and the support rod 92, and the connector hole 96 has a lower end portion of the delivery hose 82 from above. , And the lower end opening of the connector hole 96 is formed as a delivery port 98 for the fragrance beads B.

Below the connector 94, a distribution head 100 having a conical shape is arranged. The distribution head 100 has a pair of upper and lower bearings 102 with respect to the support rod 92.
It is rotatably supported via. Dispensing head 100
A hollow drive shaft 104 is connected to the lower surface of the drive shaft 104. The drive shaft 104 extends downward with the outer side of the support rod 92 concentric and is connected to a drive source (not shown). Therefore,
The driving force from the driving source is transmitted to the distribution head 100 via the drive shaft 104, whereby the distribution head 100 can rotate at a constant speed and direction. Here, the distribution head 100 is rotated counterclockwise as viewed in FIG.

On the other hand, from the upper surface of the distribution head 100, the shaft portion 106 projects toward the connector 94, and the shaft portion 10
A distribution disk 108 is fixedly attached to the disk 6, and the distribution disk 108 is rotated integrally with the distribution head 100. The distribution disk 108 is the distribution head 100.
Has a diameter substantially equal to the upper end diameter of the distribution head 100, and is therefore sufficiently smaller than the lower end diameter of the dispensing head 100.

Distributing holes 110 are formed in the peripheral portion of the distributing disk 106 at equal intervals in the circumferential direction thereof, and these distributing holes 110 rotate the distributing head 100, that is, the distributing disk 108. Accordingly, it is possible to sequentially match with the outlet 98 of the connector 94. Each distribution hole 110 has a diameter dimension capable of receiving the fragrance beads B, and its upper end opening is formed as a receiving port 112. That is, as is clear from FIG. 9, the receiving port 112 has a triangular guide recess 112a whose opening edge portion located on the front side in the rotation direction of the distribution disk 108 extends in the rotation direction.
The guide recess 112a gradually becomes deeper and faces the distribution hole 110.

Then, on the conical surface of the dispensing head 100,
The distribution grooves 114 are formed at equal intervals in the circumferential direction, and the upper ends of the distribution grooves 114 open on the upper surface of the distribution head 100, and the openings are the lower ends of the corresponding distribution holes 110 on the distribution disk 108 side. It is always facing the opening. on the other hand,
The lower end of each distribution groove 114 is connected to a drop hole 116 at the outer peripheral edge of the lower end of the distribution head 100, and these drop holes 116 are opened on the lower surface of the distribution head 100, respectively.

A blocking sheet piece 118 is arranged between the distribution disk 108 and the distribution head 100, as is apparent from FIG. The blocking sheet piece 118 is a bracket 94a that integrally projects from the lower surface of the other end of the connector 94.
The bracket 94a extends horizontally just below the distribution disk 108 so as to extend beyond the distribution hole 110. Further, as shown in FIG. 10, the blocking sheet piece 118 has the same width as the connector 94 and is always in a state of facing the delivery port 98 of the connector 94.

Here, the height dimension from the upper surface of the blocking sheet piece 118 to the upper surface of the distribution disk 108 is slightly smaller than the diameter of the fragrance beads B, and the blocking sheet piece 11
The height dimension from 8 to the lower surface of the connector 94 is set to be slightly larger than the diameter of the fragrance beads B. Furthermore,
A blocking sheet 120 is fixedly arranged immediately below the dispensing head 100. The blocking sheet 120 has a substantially square shape so as to cover the lower surface outer peripheral portion of the distribution head 100 from the lower side. However, a part of the lower surface outer peripheral portion of the distribution head 100 is exposed from the blocking sheet 120. .

That is, as shown in FIG. 9, the blocking sheet 120 has one side extending above the wrapping paper transport path 22 along the wrapping paper transport path 22, and the one side of the blocking sheet 120 is transported from the center thereof. Notch 12 extending toward the upstream side of the passage 22
2 is formed. Therefore, one rotation of the distribution head 100 causes one distribution groove 114 to move to the outlet 9 of the connector 94.
When passing through 8, the cutout 122 is formed in the distribution groove 114 over a predetermined rotation angle region from the rotation angle position immediately before that.
The drop hole 116 is opened. Note that when one of the drop holes 116 is opened, the other drop holes 116 are closed by the blocking sheet 120.

Distributing head 100 or distributing disk 10
When the receiving port 112 of each distribution hole 110 starts to match the outlet port 98 of the connector 94 with the rotation of 8, the outlet port 9
The fragrance bead B at the bottom of 8 is the receiving port 112.
While being guided by the guide recess 112a of FIG. 10, it is dropped into the distribution hole 110 through the receiving port 112 as shown in FIG. At this time, since the lower end opening of the distribution hole 110 is closed by the blocking sheet piece 118 described above, the fragrance beads B in the distribution hole 110 are immediately introduced into the distribution groove 114 on the distribution head 100 side. There is no such thing.
That is, the fragrance beads B dropped into the distribution holes 110
After that, when the distribution disk 108 further rotates and the lower end opening of the distribution hole 110 is separated from the blocking sheet piece 118 and opened, it is introduced into the corresponding distribution groove 114. Therefore, the fragrance beads B in the distribution holes 110 roll and move on the blocking sheet pieces 118 until the distribution holes 110 come off the blocking sheet pieces 118.

The fragrance beads B remaining in the outlet 98 of the connector 94 are separated by the upper surface of the distribution disk 108.
The fall is blocked. On the other hand, the dispensing head 1
When viewed from the distribution groove 114 on the 00 side, the distribution hole 110
Is aligned with the delivery port 98 on the connector 94 side, the drop hole 116 of the distribution groove 114, which forms a pair with the distribution hole 110, is located in the notch 122 and is in an open state. When the sheet comes off from the blocking sheet piece 118, the distribution groove 11 that forms a pair with the distribution hole 110 is formed.
The drop hole 116 of No. 4 is closed by the blocking sheet 120.

Therefore, the distribution groove 114 of the distribution head 100.
Even if the fragrance beads B introduced into the roll 1 roll in the distribution groove 114 and fall into the drop hole 116, the drop hole 1
16. The fragrance beads B in the drop holes 116 do not fall from the 16 and move while rolling on the blocking sheet 120 with the rotation of the distribution head 100, and the drop holes 116 form the cutouts 122 of the blocking sheet 120. It is possible to fall only after reaching.

The conical surface of the dispensing head 100 is covered with a transparent conical cover 124 (see FIG. 8) as necessary, and the conical cover 124 rolls the fragrance beads B in the distribution groove 114. At this time, due to the centrifugal force caused by the rotation of the distribution head 100, the fragrance beads B are distributed in the distribution groove 1.
Prevents jumping out of 14. Also, the cone cover 12
Openings 126 are formed in the outer peripheral edge of the lower side of the No. 4 so as to face the lower ends of the distribution grooves 114. Further, a jet nozzle 128 for jetting compressed air is provided immediately above the conical cover 124 as shown in FIG. It is arranged. This jet nozzle 12
Reference numeral 8 is connected to an air pressure source, and compressed air can be jetted into the distribution groove 114 through the opening 126 of the distribution groove 114 when the drop hole 116 of the distribution groove 114 is opened.

On the other hand, a disc-shaped supply rotor 130 is arranged between the above-mentioned distribution head 100 and the paper winding passage 22, and the supply rotor 130 is in a vertical posture along the paper winding passage 22. ing. That is, as is apparent from FIG. 8, the supply rotor 130 has its outer peripheral surface in contact with the outer peripheral edge of the lower surface of the distribution head 100 through the cutout 122 of the blocking sheet 120 described above, and within the vertical plane including the paper transport path 22. It is supposed to rotate. Therefore, the supply rotor 130 has a rotor shaft 132 that is orthogonal to the rotation axis of the distribution head 100.
Is connected to a drive source (not shown).

Here, the peripheral speed of the supply rotor 130 is equal to the moving speed of the drop hole 116 due to the rotation of the distribution head 100, and the rotation direction thereof coincides with the moving direction of the drop hole 116 on the distribution head 100 side. Has been done. Therefore, when viewed in FIG. 6, the supply rotor 130 is rotated clockwise as shown by the arrow. Supply rotor 13
On the outer peripheral surface of 0, the same number of transport holes 134 as the drop holes 116 are formed at equal intervals in the circumferential direction. Each of these transport holes 134 has a size capable of receiving one fragrance bead B, and its opening is defined as a discharge port 136.

Therefore, as shown in FIG.
When the distribution head 100 and the supply rotor 130 are rotated, the transport hole 134, that is, the discharge port 136 thereof, sequentially matches with the corresponding drop hole 116 on the distribution head 100 side, while
Among the intervals between the filter plugs CF and PF on the side of the paper transport path 22, the intervals at which the charcoal filter plug CF is located in front of the filter plugs CF and PF are sequentially matched.
That is, the rotation speeds of the supply rotor 130 and the distribution head 100 are determined based on the transport speed of the filter plug on the paper transport path 22.

The discharge port 136 of the transport hole 134 has the same shape as the receiving port 112 of the distribution hole 110 of the distribution disk 108 described above, but its guide recess 1
36a extends in the opposite direction when viewed in its rotation direction. One end of the pressure introduction hole 138 is opened at the bottom of each of the transport holes 134, and the other end is distributed on the end surface 130a of the supply rotor 130 at equal intervals on the same circumference. It is opened as.

A control disk 144 is attached to the rotor shaft 132 of the supply rotor 130 via a pair of bearings 142. The control disk 144 is fixed against rotation, and is pressed against the end surface 130a of the supply rotor 130 while covering the pressure introducing port 140 and maintaining airtightness. Therefore, the supply rotor 130 has its end surface 13
0a is rotated while being in sliding contact with the control disk 144.

A suction groove 146 and an ejection groove 148 connectable to the pressure inlet 140 are formed on the inner end surface of the control disk 144.
Are formed independently of each other. The suction groove 146 and the ejection groove 148 extend in an arc shape over a predetermined rotation angle region when viewed in the rotation direction of the supply rotor 130. That is,
The rotation angle region R1 in which the suction groove 146 is to be formed is shown in FIG.
As shown in FIG. 1, it extends from the position immediately before the rolling contact between the distribution head 100 and the supply rotor 130 to the vicinity of the paper transport path 22 for about half a circumference of the supply rotor 130, while The rotation angle region R2 in which the groove 148 is to be formed exists in the region where the supply rotor 130 is closest to the paper transport path 22.

The suction groove 146 is connected to a suction source such as a blower, while the ejection groove 148 is connected to an air pressure source. Note that, as shown in FIG. 11, the outer peripheral surface of the supply rotor 130 has a ¼ circumference on the lower right side of the guide 15
Covered by 0s. If the above-described supply rotor 130 is combined with the distribution head 100, the rotation of these causes one transport hole 134 to match the corresponding drop hole 116 on the distribution head 130 side, and at this time, the drop hole 116 is blocked. Since the cutout 122 of the sheet 120 has entered, the fragrance beads B held therein are dropped from the drop hole 116 into the transport hole 134.

Here, at the time when the drop hole 116 and the transport hole 134 are aligned with each other, the distribution groove 1 which is continuous with the drop hole 116.
14, the distribution hole 110 on the side of the distribution disk 108 that is paired with the distribution groove 114 also coincides with the outlet 98 of the connector 94, and therefore, at this point, a new fragrance bead is added to the distribution hole 110. B will be dropped.

When the drop hole 116 and the transport hole 134 are aligned with each other, the compressed air from the jet nozzle 128 is sent into the distribution groove 114, and at this time,
The transport hole 134 is connected to the suction groove 146 of the control disk 144 through the pressure introduction hole 138. Therefore, since the fragrance beads B in the drop hole 116 receive pressure of compressed air from the upper side and are sucked from the lower side at the same time, the discharge of the fragrance bead B from the drop hole 116 to the transport hole 134 is surely performed. become.

After that, the fragrance beads B transferred to the transport hole 134 are transported downward while being suction-held, as the supply rotor 130 rotates, and then the transport hole 13 thereof.
When 4 matches the space between the filter plugs CF and PF on the paper transport path 22, the fragrance beads B in the transport hole 134 are dropped into that space. At this point, the connection between the transfer hole 134 and the suction groove 146 has already been cut off, and the transfer hole 134 is connected to the ejection groove 148 of the control disk 144 through the pressure introduction hole 138. Therefore, the fragrance beads B in the transport holes 134 are subjected to the pressure of the compressed air and are reliably discharged toward the intervals.

When the distribution head 100 and the supply rotor 130 continue to rotate as described above, the supply rotor 130 receives the fragrance beads B one by one from the distribution head 100, and the fragrance beads B are fed to the paper transport path 22. It will be sequentially supplied at the interval between the upper filter plugs CF and PF. The difference between the other bead distribution unit 90 located on the downstream side of the wrapping paper conveyance path 22 and the above-mentioned bead distribution unit 88 is that the bead distribution unit 88 flows through the wrapping paper conveyance path 22 through a filter plug. While the charcoal filter plug CF supplies the fragrance beads B toward the space between the filter plugs located downstream, the bead distribution unit 90 has the plain filter plug PF at the space between the filter plugs located downstream. The fragrance beads B are to be supplied. Even if the target intervals are different in this way, the pitch PT of these intervals is the same, so the bead distribution unit 88,
There is no difference in the configuration of 90.

Therefore, when the filter plug travels along the wrapping paper P on the wrapping paper transport path 22 and passes through the supply device 44, that is, the pair of bead distributing units 88 and 90, the fragrance beads B are supplied to all the intervals between the filter plugs. Will be done. According to the above bead distribution units 88 and 90, even if the transport speed of the filter plug on the paper web transport path 22 is high, compared to this transport speed, the outlet port 98 of the connector 94 and the distribution hole 110 on the distribution disk 108 side. The relative speed that occurs between and can be slowed. That is, even if the peripheral speed of the outer peripheral surface of the supply rotor 130 and the outer peripheral edge of the lower end of the distribution head 100 are set to be the same as the conveying speed, the peripheral speed of the distribution disk 108 becomes slower than the conveying speed due to the difference in diameter. .

Therefore, the scented beads B in the outlet port 98 of the connector 94 have only their own weight, and the distribution disk 108.
Will be surely dropped into each distribution hole 110 of
As a result, when supplying the fragrance beads B to the distribution holes 110, an excessive force is not applied to the fragrance beads B,
It is possible to reliably prevent breakage or damage of the fragrance beads B.

Further, from the distribution head 100 to the supply rotor 1
At the time of transferring the fragrance beads B to 30, or the supply rotor 13
At the time of the final supply of the fragrance beads B from 0 to the space between the filter plugs, the drop hole 1 on the distribution head 100 side
16 does not cause relative speed between the conveying hole 134 on the side of the supply rotor 130 and between the conveying hole 134 and the above-mentioned interval, and the transfer and the final supply can be smoothly performed. It is possible, and again, the fragrance beads B are not damaged or damaged.

The present invention is not limited to the above-mentioned embodiment, but various modifications can be made. For example, in one embodiment, a pair of bead distribution units 88 and 90 are provided, but if the charcoal filter plug and the plain filter plug have the same length, only one bead distribution unit is provided and each bead distribution unit between the filter plugs. Perfume beads can be supplied at intervals.

Further, although the type of the filter plug forming the gap is different in one embodiment, the filter plug may be the same, and in this case, the plug hopper is 1
One is enough. Further, in the practice of the present invention, the supply rotor 130 of the bead distribution unit is not indispensable, and it is also possible to directly supply the fragrance beads from the drop hole 116 of the distribution head 100 between the filter plugs on the paper transport path. . In this case, the distribution head 100 needs to be rotationally driven with the moving direction of the drop hole 116 on the side of the paper transport path and the transport direction of the filter plug aligned.

As described above, according to the filter rod manufacturing machine of the present invention, the hopper side and the wrapping paper conveying path side are connected to each other, and the connection path for guiding and introducing the fragrance beads is provided on the wrapping paper conveying path. While providing a discharge port whose moving speed matches the moving speed of the filter plug, for the receiving port that periodically matches the sending port on the hopper side, set the relative speed of the receiving port to the sending port to the moving speed. It is kept low in comparison. Therefore, even if the transport speed of the filter plug is high, it is possible to supply the fragrance beads to the connection path from the fixed-side outlet through the receiving port without applying an excessive force to the fragrance beads, and the fragrance beads are not damaged or damaged. The fragrance beads can be stably and reliably supplied to the space between the filter plugs on the paper transport path without damage. As a result, it is possible to easily cope with the increase in the speed of the manufacturing machine, and further, it is possible to improve the quality of the filter rod.
