Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for supplying spherical objects one by one to a surface to be supplied which moves at a high speed on a conveying path, and particularly to a spherical object suitable for relatively soft spherical objects. Regarding the feeding device.

[0002]

2. Description of the Related Art For example, with respect to a cigarette with a filter, if a fragrance bead that emits an aroma only after being crushed is contained in the filter chip as a spherical substance, even if the smoker is a cigarette of the same brand, By selecting whether or not the fragrance beads are crushed with a finger, two kinds of tastes can be enjoyed.

The filter chip as described above can be realized by accommodating the fragrance beads instead of the activated carbon in a known triple filter chip. More specifically, in manufacturing a cigarette with a filter, a normal triple filter chip is obtained by cutting a long filter rod into a predetermined length, and the filter rod is transported along a transport path. While supplying the filter plugs on the wrapping paper at a predetermined interval, particles of activated carbon are supplied between the filter plugs, and these are wrapped with the wrapping paper in the same manner as the cigarette. It is molded in advance.

Therefore, the filter rod manufacturing machine is equipped with a supply device for supplying particles of activated carbon toward the space between the filter plugs on the wrapping paper. If this supply device is used, the filter plug on the wrapping paper is used. In the meantime, it is possible to supply the fragrance beads.

[0005]

However, since the above-mentioned feeding device has been developed on the premise of treating hard activated carbon, if relatively soft fragrance beads are handled by such a feeding device, fragrance beads will be produced. It is vulnerable to breakage or damage before supplying between filter plugs,
As a result, the production yield of the filter rod is also reduced.

On the other hand, in order to improve the productivity of cigarettes with a filter, the machine for manufacturing the filter rod tends to be further increased in speed. Therefore, the supply speed of the fragrance beads by the supply device must be increased. In this case, the force applied to the fragrance beads also inevitably becomes large, and the fragrance beads are more likely to be damaged or damaged. In this respect, although it is possible to eliminate the above problems by making the fragrance beads themselves hard, if the fragrance beads are too hard, the smoker may not be able to crush the fragrance beads even if they are pinched with fingers from the outside of the filter during smoking. is there.

The present invention has been made in view of the above-mentioned circumstances, and the purpose thereof is to make it possible to supply spherical objects without causing breakage or damage, and to easily cope with high speed. The object of the present invention is to provide a feeder for spherical objects.

[0008]

SUMMARY OF THE INVENTION A spherical object supply device of the present invention is provided above a conveying path, and is provided with a hopper unit for sending out the spherical objects one by one, and the supply target to the outlet of the hopper unit. One that moves at a speed slower than the moving speed of the surface and is cyclically connected to the sending outlet and that can receive a spherical object from the sending outlet and a speed that matches the moving speed of the supplied surface From the same direction as the moving direction of the supply surface, the discharge opening opened when positioned periodically on the supply surface and the receiving opening and the receiving opening are connected and introduced from the receiving opening. And a connecting path means for guiding the formed spherical object to the discharge port.

Preferably, the connection path means is rotatably arranged immediately below the outlet of the hopper unit, and has a truncated cone-shaped supply head and a tapered outer peripheral surface of the supply head. Formed at equal intervals in the circumferential direction, and provided with a connection groove for guiding the spherical object,
As a result, one end of each connection groove opens on the upper surface of the supply head to define the receiving port, and the other end opens on the lower surface of the supply head to define the ejection port.

[0010]

According to the above-mentioned feeding device, when the receiving port is aligned with the delivery port of the hopper unit while moving at a speed lower than the moving speed of the surface to be supplied, one spherical object is delivered from the delivery port. Is received in the receiving port, and this spherical object is guided toward the discharging port through the connecting path means. Then, after this, when the discharge port moves at the same speed as the supply surface and is positioned on the supply surface from the same direction as the moving direction of the supply surface, the discharge port is opened, A spherical object is supplied from the discharge port onto the surface to be supplied.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to FIG. 1, there is shown a spherical object feeder according to an embodiment, which is incorporated in a filter rod manufacturing machine as described above.
In FIG. 1, only the wrapping paper transport path 2 of the filter rod manufacturing machine is shown by a chain line, and the wrapping paper P can travel on this wrapping paper transport path 2 in one direction at a predetermined speed together with a garniture tape (not shown). Has become.

When the wrapping paper P passes through the feeding device,
Although not shown in FIG. 1, different types of filter plugs are alternately supplied on the wrapping paper P at predetermined intervals. The supply device is provided with a hopper unit 4 located above the paper web transport path 2, and the hopper unit 4 stores a large number of spherical objects, that is, fragrance beads.
have. The hopper 4 has a box shape with an upper surface opened, and a bottom wall 8 thereof is inclined downward toward the paper web transport path 2.

As is apparent from FIG. 2, the lower end of the front wall of the hopper 4 projects forward with a predetermined gap between it and the bottom wall 8, and this gap extends in the width direction of the hopper 6. It is exit 10. Also, the bottom wall 8 of the hopper 6 continues to an extension plate 12 which extends beyond the outlet 10.

At the outlet 10 of the hopper 6, the outlet 1
The dam roller 14 is rotatably arranged so as to close 0. The outer peripheral surface of the dam roller 14 is formed of a rubber layer 16, and the gap between the dam roller 14 and the extension plate 52 is set to be slightly larger than the diameter of the fragrance beads B. Dam roller 14
The roller shaft is connected to a drive source (not shown) and can be gently rotated at a constant speed. Here, the rotation direction of the dam roller 14 is set so that the outer peripheral surface of the hopper 6 located on the outlet 10 side moves upward from below, as indicated by the arrow in FIGS. 1 and 2. There is. Therefore, even if the fragrance beads B in the hopper 6 are going to pass through the outlet 10, the fragrance beads in the laminated state will be
Therefore, the fragrance beads B are discharged from the gap while rolling on the extension plate 12 in a single layer.

Further, in the hopper 6, its outlet 10
Since the fragrance beads B are stacked in the vicinity of and are pushed up by the gentle rotation of the dam roller 14, the fragrance beads B can be smoothly discharged from the gap. On the other hand, as shown in FIG. 1, a partition bar 18 is attached to the center of the extension plate 12 described above, and the upper end of the partition bar 18 is positioned near the dam roller 14. , And this dam roller 1
4 extends toward the lower edge of the extension plate 12.

On the extension plate 12, a pair of partition bars 20 and 22 are mounted on both sides of the partition bar 18, and the upper ends of the partition bars 20 and 22 correspond to the dam roller 14. It is located in the vicinity of the end portion and extends obliquely from this end portion toward the partition bar 18. On the extension plate 12, the area partitioned by each partition bar and the partition bar 18 is a pair of bead trays 2
4 and 26, these bead trays 2
4, 26, the width thereof is gradually reduced downward. Therefore, the fragrance beads B discharged from the hopper 6 through the dam roller 14 are the same as the pair of bead trays 24, 2.
6 will be sorted and received, and will be guided downward while rolling on each bead tray.

It should be noted that the bead trays 22 and 24 are shown in FIG.
A large number of through holes 25 are formed as shown in FIG. Further, on the extension plate 12, a pair of guide bars 2 are located on both sides of the lower end of the partition bar 18.
8 and 30 are attached, and between the guide bar and the partition bar 18, a derivation passage for the fragrance beads B is defined. The passage width of these outlet passages is slightly larger than the diameter of the fragrance beads B, and therefore the scent beads B pass through the outlet passage in a line.

A pair of agitator rollers 32 and 34 are rotatably arranged on the extension plate 12, and a part of the outer peripheral surfaces of the agitator rollers 32 and 34 respectively correspond to the partition bars 20 and 34. The lower end of 22 and the guide bars 28 and 30 are connected. That is, the agitator rollers 32 and 34 are flat rollers,
A part of the outer peripheral surface closes between the lower ends of the partition bars 20 and 22 and the upper ends of the guide bars 28 and 30. Further, the lower ends of the partition bars 20, 22 and the upper ends of the guide bars 28, 30 are formed as arcuate surfaces along the outer peripheral surface of the corresponding agitator roller, and moreover, the distance between the agitator roller and the partition bar 18 is set. , The width of the outlet passage is matched. Therefore, the inner surface from the partition bar to the guide bar is smoothly connected via the agitator roller.

The outer peripheral surfaces of the agitator rollers 32 and 34 are covered with a rubber layer 36 as with the dam roller 14 described above, and the roller shafts are connected to a drive source (not shown) so that the agitator rollers are The outer peripheral surface located on the partition bar 18 side can be rotated in opposite directions and gently so that the outer peripheral surface moves upward from below.

If the agitator rollers 32, 34 are gently rotated in the above-mentioned direction, the perfume located on the agitator rollers 32, 34 side of the perfume beads B concentrated in the lower area on each bead tray 24, 26. The beads B are pushed up by the rotation of the agitator roller, and only the fragrance beads B moving along the partition bar 18 can smoothly enter into the outlet passage between the partition bar 18 and the guide bars 28, 30. Therefore, the fragrance beads B are guided in a line inside the outlet passage without being clogged at the inlets of these outlet passages.

Connectors 38, 4 are provided at the outlets of the outlet passages.
Flexible delivery hoses 42, 44 are connected via 0. Each of these connectors 38, 40 has a connecting hole inside which one end is connected to the outlet of the outlet passage, and the other end has a connection hole into which one end of the delivery hose, that is, the upper end, is inserted. Fragrance beads B as with
Has a passage cross-sectional area that allows the passage of each of them, and their inner surfaces are also smoothly connected. Therefore, the fragrance beads B that have entered the discharge passage are guided into the delivery hose through the connector from the discharge passage.

The bead trays 24 and 26 described above are used.
Is a transparent cover plate 4 as shown in FIG.
Covered by 6. The delivery hoses 42 and 44 are shown in FIG.
As shown in FIG. 5, the cable extends downward and is connected to the pair of connectors 54, respectively. These connectors 54 are separated from each other along the above-described paper web transport path 2 and are attached to the support rods 52 of the corresponding supply heads 48 and 50.

That is, FIG. 3 shows one connector 54 located upstream of the paper web transport path 2 and its corresponding supply head 48 in a partially cutaway manner. Thus, the connector 54 is fixed to the upper end of the support rod 52. More specifically, the connector 54 has a rectangular shape, one end of which is fixed to the support rod 52 by penetrating the upper end of the support rod 52, and the other end of which is horizontally directed toward the paper web transport path 2. It is projected.

Although not shown, the lower end side of the support rod 52 is vertically extended and fixed downward, and is fixed to the base of the filter rod manufacturing machine. The connector 54 is formed with a connector hole 56 that is located between the other end and the support rod 52 and penetrates vertically. The lower end of the delivery hose 42 is inserted into the connector hole 56 from above. . Therefore, the delivery hose 42 and the connector hole 56
Are connected to each other, and the lower end opening of the connector hole 56 is defined as the delivery port 58 of the hopper unit 4.

The supply head 48 is provided with a truncated cone-shaped distribution rotor 60 disposed below the connector 54. The distribution rotor 60 is rotatably supported by the support rod 52 via a pair of upper and lower bearings 62. Has been done. Therefore, the distribution rotor 60 is rotatable in the horizontal plane. A hollow drive shaft 64 is connected to the lower surface of the distribution rotor 60. The drive shaft 64 extends downward with the outer side of the support rod 52 concentric with it, and is connected to a drive source (not shown). Therefore, when the driving force from the driving source is transmitted to the distribution rotor 60 via the drive shaft 64, the distribution rotor 60 is rotated at a constant speed and direction. Here, the distribution rotor 6
0 is rotated counterclockwise as viewed in FIG.

On the other hand, from the upper surface of the distribution rotor 60 on the small diameter side, a shaft portion 66 projects toward the connector 54,
A distribution disk 68 is fixedly attached to the shaft portion 66. This distribution disk 68 is the same as the connector 5
It is located immediately below 4 and is rotated integrally with the distribution rotor 60. The distribution disk 68 has a diameter substantially equal to the diameter of the upper surface of the distribution rotor 60. Therefore, the diameter of the distribution disk 68 is sufficiently smaller than the diameter of the lower surface side of the distribution rotor 60. .

At the peripheral edge of the distribution disk 68, distribution holes 70 are formed so as to extend vertically at equal intervals in the circumferential direction, and these distribution holes 70 rotate the distribution rotor 60, that is, the distribution disk 68. Accordingly, it is possible to sequentially match the outlet 58 on the connector 54 side and connect to the outlet 58. Each distribution hole 70 has a diameter dimension capable of receiving the fragrance beads B, and an upper end opening thereof is formed as a receiving port 72. That is, as shown in FIG. 4, the receiving port 72 is a triangular guide recess 72a whose opening edge portion located on the front side in the rotation direction of the distribution rotor 60 extends in the rotation direction. The guide recess 72a gradually becomes deeper and faces the distribution hole 72.

On the outer peripheral surface of the distribution rotor 60, that is, on its tapered surface, distribution grooves 74 are formed at equal intervals in the circumferential direction, and the upper ends of the distribution grooves 74 are opened on the upper surface of the distribution rotor 60. However, the opening faces the lower end opening of the corresponding distribution hole 70 of the distribution disk 68. Here, since the distribution rotor 60 and the distribution disk 68 are integrally rotated as described above, the upper end opening of the distribution groove 74 and the lower end opening of the corresponding distribution hole 70 are always opposed to each other.

On the other hand, the lower end of each distribution groove 74 is connected to a drop hole 76 formed in the outer peripheral portion on the lower surface side of the distribution rotor 60, and these drop holes 76 are opened in the lower surface of the distribution rotor 60, respectively. There is. A blocking sheet 78 is disposed between the distribution disk 68 and the distribution rotor 60 as shown in FIG. The blocking sheet piece 78 is attached to the bracket 54a integrally protruding from the lower surface of the other end of the connector 54 described above, and extends horizontally directly below the distribution disk 68 from the bracket over the distribution hole 70. There is. As shown in FIG. 5, the blocking sheet piece 78 has the same width dimension as the connector 54 and is always in a state of facing the delivery port 56 of the connector 54.

Here, the height dimension from the upper surface of the blocking sheet piece 78 to the upper surface of the distribution disk 68 is slightly smaller than the diameter of the fragrance beads B, and the height from the blocking sheet piece 78 to the lower surface of the connector 54. The length is set to be slightly larger than the diameter of the fragrance beads B. Further, a blocking sheet 80 is fixedly arranged immediately below the distribution rotor 60. The blocking sheet 80 has a substantially square shape that covers the outer peripheral portion of the lower surface of the distribution rotor 60 from below.
However, a part of the outer peripheral portion of the lower surface of the distribution rotor 60 is exposed from the blocking sheet 80.

That is, as will be clearer with reference to FIG. 4, the blocking sheet 80 has one side extending above the wrapping paper transport path 2 along the wrapping paper transport path 2, and this one side has a wrapping paper from the center thereof. Notch 82 extending toward the upstream side of the transport path 2
Are formed. Therefore, when one distribution groove 74 passes through the outlet 58 of the connector 54 due to the rotation of the distribution rotor 60, the notch 82 of the distribution groove 74 extends from the position of the rotation angle immediately before that to the predetermined rotation angle region. Fall hole 76
It is supposed to open. Note that when one of the drop holes 76 is opened, the other drop holes 76 are closed by the blocking sheet 80. Therefore, the lower end opening of the drop hole 76 defines the discharge port 76a of the fragrance bead B, and therefore the distribution groove 74 and the drop hole 76 are the same as the receiving port 7 described above.
2 and the discharge port 76a are connected to each other.

With the rotation of the distribution rotor 60, that is, the distribution disk 68, the receiving ports 72 of the distribution holes 70 are connected to the connector 54.
When the fragrance beads B located at the lowest position in the outlet 58 are guided by the guide recess 72a of the outlet 72, the perfume beads B are distributed through the outlet 72 as shown in FIG. It is dropped into the hole 70. At this time, the lower end opening of the distribution hole 70 has the above-mentioned blocking sheet piece 78.
The perfume beads B in the distribution hole 70 are not immediately introduced into the distribution groove 74 of the distribution rotor 60 because they are closed by the. That is, in the fragrance beads B dropped into the distribution hole 70, the distribution disk 68 is further rotated, and the lower end opening of the distribution hole 70 is blocked by the blocking sheet piece 78.
When opened apart from, it will be introduced into the corresponding distribution groove 74. Therefore, the fragrance beads B in the distribution holes 70
Will move while rolling on the blocking sheet piece 78 until the distribution hole 70 comes off the blocking sheet piece 78.

The fragrance beads B remaining in the outlet 58 of the connector 54 are prevented from falling by the upper surface of the distribution disk 68. On the other hand, the distribution rotor 60
Looking at the distribution groove 74 on the side, when the distribution hole 70 matches the delivery port 58 on the connector 54 side, the distribution hole 7 is formed.
The drop hole 76 of the distribution groove 74, which is paired with 0, is the cutout 82.
However, when the distribution hole 70 is disengaged from the blocking sheet piece 78, the drop hole 76 of the distribution groove 74 that forms a pair with the distribution hole 70, that is, the discharge port 76a is blocked. The seat 80 is in a closed state.

Therefore, the fragrance beads B introduced into the distribution groove 74 of the distribution rotor 60 roll in the distribution groove 74,
Even if it falls into the drop hole 76, the discharge port 7 of this drop hole 76
6a does not fall, and the fragrance beads B in the drop hole 76 are blocked by the rotation of the distribution rotor 60 and the blocking sheet 8
It is possible to fall only when the falling hole 76 reaches the notch 82 of the blocking sheet 80 and moves while rolling over 0.

The tapered surface of the distribution rotor 60 is covered with a transparent conical cover 84 (see FIG. 3) as required, and the conical cover 84 rolls the fragrance beads B in the distribution separation 74. At this time, the fragrance beads B are prevented from jumping out of the distribution groove 74 due to the centrifugal force caused by the rotation of the distribution rotor 60. Further, an opening 86 is formed in the lower outer peripheral edge of the conical cover 84 so as to face the lower end portion of the distribution groove 74.
Are formed respectively, and a jet nozzle 88 for ejecting compressed air is arranged immediately above the conical cover 84 as shown in FIG. The jet nozzle 88 is connected to an air pressure source, and when the drop hole 76 of the distribution groove 74 is opened, compressed air can be jetted into the distribution groove 74 through the opening 86 of the distribution groove 74. ing.

On the other hand, a disc-shaped supply rotor 90 is provided between the distribution rotor 60 and the paper web transport path 2 described above.
Are arranged, and the supply rotor 90 has
It has a vertical posture along the line. That is, the supply rotor 90
As is apparent from FIG. 3, the outer peripheral surface of the sheet is rotated in the plane including the paper transport path 2 while being in contact with the outer peripheral edge of the lower surface of the distribution rotor 60 through the cutout 82 of the blocking sheet 80 described above. . Therefore, the supply rotor 90 has a rotor shaft 92 that is orthogonal to the rotation axis of the distribution rotor 60, and this rotor shaft 92 is connected to a drive source (not shown).

Here, the peripheral speed of the supply rotor 90 is equal to the moving speed of the drop hole 76, that is, the discharge port 76a in accordance with the rotation of the distribution rotor 60, and the rotation direction along the paper transport path 2 is also on the distribution rotor 60 side. It is aligned with the moving direction of the drop hole 76. Therefore, as seen in FIG. 1, the supply rotor 90 is rotated clockwise as shown by the arrow, and the outer peripheral surface thereof is the surface to which the fragrance beads B are supplied.

On the outer peripheral surface of the supply rotor 90, the same number of transport holes 94 as the drop holes 76 are formed at equal intervals in the circumferential direction. One of these transport holes 94 holds one fragrance bead B.
It has a size capable of receiving a bask and its opening is defined as a receiving port 96. Therefore, as shown in FIG. 6, when the distribution rotor 60 and the supply rotor 90 are rotated, the conveying holes 94, that is, the receiving ports 96 thereof, are distributed.
The discharge ports 76a of the corresponding drop holes 76 on the 0 side sequentially match.

On the other hand, as is clear from FIG.
Different types of filter plugs CF and PF are alternately arranged at regular intervals on the wrapping paper P conveyed above, and the receiving port 96 of the supply rotor 90 has a space between these filter plugs. Among them, the space between the filter plug CF and the filter plug PF can be sequentially matched with each other when viewed in the transport direction of the wrapping paper P. Therefore, the distribution rotor 6
0 and the rotation speed of the supply rotor 90, that is, the peripheral speed thereof are matched with the conveyance speed of the wrapping paper P and the filter plug on the wrapping paper conveyance path 2.

The filter plug CF is a filter fiber in which particles of activated carbon are mixed.
The filter plug PF consists of filter fibers only, in which case the filter plug PF has a length twice that of the filter plug CF. The receiving port 96 of the transport hole 94 has the same shape as the receiving port 72 of the distribution hole 70 on the distribution disk 68 side described above, but the guide recess 96a thereof extends in the opposite direction when viewed in the rotational direction.

One end of a pressure introducing hole 98 is opened at the bottom of each conveying hole 94, and the other end is opened as a pressure introducing port 100 on the end face 90a of the supply rotor 90. These pressure inlets 100 are distributed at equal intervals on the same circumference. A control disk 104 is attached to the rotor shaft 92 of the supply rotor 90 via a pair of bearings 102. The control disk 104 is fixed against rotation, and is pressed against the end surface 90a of the supply rotor 90 so as to cover the pressure introducing port 100 in an airtight manner. Therefore, the supply rotor 90 is rotated while the end surface 90 a of the supply rotor 90 is in sliding contact with the control disk 104.

On the inner end surface of the control disk 104, the suction groove 106 and the ejection groove 1 connectable to the pressure introducing port 100 are provided.
08 are formed independently of each other. The suction groove 106 and the ejection groove 108 extend in an arc shape over a predetermined rotation angle region as viewed in the rotation direction of the supply rotor 90. That is, the rotation angle region where the suction groove 106 is to be formed is R1.
Exists over a half circumference of the supply rotor 90 from the position immediately before the rolling contact point between the distribution rotor 60 and the supply rotor 90 to the vicinity of the paper web transport path 2 as shown in FIG.
On the other hand, the rotation angle region R2 to which the ejection groove 108 is to be supplied
Exists in the region where the supply rotor 90 is closest to the paper web transport path 2.

The suction groove 106 is connected to a suction source such as a blower, while the ejection groove 108 is connected to an air pressure source. As shown in FIG. 6, the supply rotor 9
The outer peripheral surface of 0 is covered with the guide 110 on the lower right ¼ circumference. When the distribution rotor 60 is combined with the above-mentioned supply rotor 90, these rotations cause
When one of the transport holes 94 is aligned with the corresponding drop hole 76 on the distribution rotor 60 side, at this time, since the drop hole 76 has entered the notch 82 of the blocking sheet 80, the fragrance beads B held therein are formed. Will be dropped from the drop hole 76 into the transport hole 94.

Here, at the time when the drop hole 76 and the transport hole 94 are aligned with each other, regarding the distribution groove 74 connected to the drop hole 76, the distribution hole 70 on the side of the distribution disk 68 that forms a pair with the distribution groove 74 is also. It coincides with the outlet 58 of the connector 54 at the same time, so that at this point, new fragrance beads B are dropped into the distribution holes 70. Further, when the drop hole 76 and the transfer hole 94 are aligned with each other, the compressed air from the jet nozzle 88 is sent into the distribution groove 74, and at this time, the transfer hole 94 passes through the pressure introduction hole 98 to the control disk. It is in a state of being connected to the suction groove 106 of 104. Therefore, since the fragrance beads B in the drop hole 76 receive the pressure of the compressed air from above and are sucked from below, the transfer of the fragrance beads B from the drop hole 76 to the transport hole 94 is surely performed. become.

After that, the fragrance beads B transferred to the transport hole 94 are sucked and held and are transported downward as the supply rotor 90 rotates, and the transport hole 94 is wound on the wrapping paper P on the wrapping paper transport path 2. When the vacant space between the filter plugs CF and PF of No. 1 is matched, the fragrance beads B in the transport hole 94 are dropped into the vacant space. At this point, the connection between the transport hole 94 and the suction groove 106 has already been cut off,
The transfer hole 94 is connected to the control disk 10 through the pressure introducing hole 98.
4 is in the state of being connected to the ejection groove 108. Therefore, the fragrance beads B in the transport hole 94 are surely supplied to the void by receiving the pressure of the compressed air.

When the distribution rotor 60 and the supply rotor 90 continue to rotate as described above, the supply rotor 90 receives the fragrance beads B one by one from the distribution rotor 60, and the fragrance beads B are fed to the paper transport path 2. The upper wrapping paper P will be sequentially supplied to the space between the filter plugs CF and PF. The supply head 50 located on the downstream side of the paper web transport path 2 has the same structure as the supply head 48 described above, and therefore, members and parts having the same function in the drawings have the same reference numerals. The description will be omitted and only the different points will be described below.

As described above, the supply head 48 sees the flow of the filter plug running along with the wrapping paper P on the wrapping paper transport path 2, and the charcoal filter plug CF is located in the space between the filter plugs in the space between the filter plugs. While the beads B are supplied, the supply head 50 supplies the fragrance beads B to the space between the filter plugs where the plain filter plug PF is located on the downstream side.

Even if the vacant spaces between the target filter plugs in the supply heads 48 and 50 are different, the pitches of these vacant spaces are the same, so that the structure of the supply heads 48 and 50 may be different. There is no. Therefore, when the filter plugs travel together with the wrapping paper P on the wrapping paper transport path 2 and these filter plugs pass below the pair of supply heads 48, 50, the fragrance beads B are provided in all the spaces between the filter plugs.
Will be supplied.

According to the supply heads 48 and 50 described above,
Even if the transport speed of the wrapping paper P on the wrapping paper transport path 2, that is, the filter plug is fast, the moving speed of the distribution hole 70 on the distribution disk 68 side with respect to the delivery port 58 of the connector 54 can be made slower than this transport speed. . That is, the supply rotor 9
Even if the peripheral speed of the outer peripheral surface of 0 and the peripheral edge of the lower end of the distribution rotor 60 are equal to the transport speed, the diameter of the upper surface of the distribution rotor 60 is different because of the difference in diameter between the upper surface and the lower surface of the distribution rotor 60. The peripheral speed of the distribution disk 68, which is approximately equal to the size, is slower than the transport speed.

Therefore, the fragrance beads B in the outlet 58 of the connector 54 are surely dropped into the respective distribution holes 70 of the distribution disk 68 only by its own weight, and as a result, the fragrance to the distribution holes 70 is formed. When the beads B are supplied, no excessive force is applied to the fragrance beads B, and the fragrance beads B can be reliably prevented from being damaged or damaged. Also,
Even when the fragrance beads B are transferred from the distribution rotor 60 to the supply rotor 90 or when the fragrance beads B are finally supplied from the supply rotor 90 to a space between the filter plugs, the drop holes on the distribution rotor 60 side. No relative velocity is generated between the transfer hole 76 on the side of the supply rotor 90 and the transfer hole 94 on the side of the supply rotor 90 and between the transfer hole 94 and the empty space, and the transfer and the final supply can be smoothly performed. Also here, the fragrance beads B are not damaged or damaged.

The present invention is not limited to the above-described embodiment, but various modifications can be made. For example, the supply device according to the embodiment includes a pair of supply heads along the paper transport path, but the supply head may be one. In this case, in order to be able to supply the fragrance beads to all the voids between the filter plugs that travel with the wrapping paper on the wrapping paper transport path, the distribution holes of the distribution disk in the supply head, the distribution grooves of the distribution rotor, and the transport holes of the supply rotor. It is sufficient to double the number of the above, while setting the intervals of the drop holes of the distribution groove and the transport holes in accordance with the intervals of the voids between the filter plugs. Further, if the charcoal filter plug CF and the plain filter plug PF have the same length, the intervals of continuous voids between these filter plugs will have the same pitch, so that the distribution holes, the distribution grooves, and the transport The holes need only double the number.

Further, the supply device does not necessarily need the supply rotor, and if the distribution rotor is rotated in the opposite direction,
It is also possible to directly supply the fragrance beads from the drop hole of the distribution rotor to the space between the filter plugs, and in this case, the wrapping paper P on the wrapping paper transport path 2 serves as the supply surface of the fragrance beads B. Become. Furthermore, the supply device of the present invention is not limited to supplying the fragrance beads to the space between the filter plugs, it can be applied to supply various spherical objects, and the spherical objects are relatively soft. , Which is particularly suitable.

As described above, according to the spherical object feeder of the present invention, the spherical object is moved at a speed lower than the moving speed of the surface to be supplied and is periodically connected to the outlet of the hopper unit. And a discharge port that moves at a speed matching the moving speed of the supplied surface and that is periodically positioned on the supplied surface in the same direction as the moving direction of the supplied surface. Since the port and the discharge port are connected by the connection path means, even if the moving speed of the supplied surface is high, the relative speed of the receiving port to the delivery port of the hopper unit is reduced to Connection can be made, and when introducing the spherical object from the sending port to the receiving port, the spherical object can be smoothly and stably introduced into the receiving port without applying an excessive force to the spherical object. . On the other hand, even when the spherical object is finally supplied to the surface to be supplied, since a relative speed difference does not occur between the discharge port and the surface to be supplied, again, too much force is applied to the spherical object. There is an excellent effect that the spherical object can be supplied from the discharge port to the surface to be supplied without adding.
