Description

Granular feeder and method for supplying the same

The present invention relates to a feeder for supplying granular materials in a row and a method for supplying the same, and more particularly to a feeder and supplying method for granular materials suitable for supplying easily fragile granular materials.

This type of feeder is disclosed in each of the following Patent Documents 1 to 3, for example.
The feeder of Patent Document 1 includes a hopper for an object, and a vertical rotating wheel disposed immediately below the outlet of the hopper. The rotating wheel has a plurality of pockets on an outer peripheral surface thereof. They are arranged at intervals in the circumferential direction.
According to the feeder of Patent Document 1, during the rotation of the rotating wheel, each pocket receives an object one by one from the outlet of the hopper, and forms a row of articles extending in the circumferential direction of the rotating wheel on the outer periphery of the rotating wheel. Such a row of articles is supplied in the direction of rotation of the rotating wheel.

The feeder of Patent Document 2 includes a bead supply bowl and a plurality of bead passages that extend radially from the bead supply bowl and rotate together with the bead supply bowl. The beads are supplied one by one to the pocket formed on the outer periphery of the bead supply wheel. Therefore, also in the case of the feeder of Patent Document 2, a row of beads extending in the circumferential direction is formed on the outer periphery of the bead supply wheel. Such a row of beads is supplied in the direction of rotation of the bead supply wheel.

The feeder of Patent Document 3 includes a rotating disk that receives a supply of parts, and this rotating disk is disposed to be inclined with respect to a horizontal plane. The outer peripheral edge of the rotating disk has an alignment groove extending over the entire circumference. Since the rotating disk is inclined, the parts supplied onto the rotating disk move downward on the rotating disk and are received by the alignment grooves. Accordingly, the alignment grooves form a row of parts extending in the circumferential direction of the rotating disk. Such a row of parts is supplied in the direction of rotation of the rotating disk.

JP2009-508524A JP2011-505154A JP2003-095420A

In the case of the feeder of Patent Document 1, since the rotation of the rotating wheel scrapes up the object in the hopper, collision between objects in the hopper and collision between the hopper wall and the object cannot be avoided. Therefore, the feeder of Patent Document 1 cannot be applied to a fragile object.

In the case of the feeder of Patent Document 2, the supply speed of the rows of beads is limited by the rotation speed of the bead supply bowl, and it is difficult to increase the supply speed. That is, if the rotation speed of the bead supply bowl is increased, the beads cannot be discharged from the bead supply bowl to the bead passage.

The feeder of Patent Document 3 scoops up a row of parts, scoops it up with a claw, and removes it from the alignment groove. However, when the part is a granular material that easily rolls, the article rolls on the scooping claw, and the article cannot be stably guided to the subsequent discharge path. Therefore, the feeder of patent document 3 is not suitable for supply of a granular material.

An object of the present invention is to provide a feeder for granular materials that can be stably supplied in a line without breaking the granular materials, and a method for supplying the same.

The above objective is accomplished by a granular feeder according to the present invention,
A rotatable rotating disk that includes an upper surface that is inclined with respect to a horizontal plane and on which the granular material is supplied;
An enclosure member that extends along the outer peripheral edge of the rotating disk and prevents the dropping of particulate matter from its upper surface;
An alignment apparatus for forming a row in which the granular material is arranged in the circumferential direction of the rotating disk from the granular material on the upper surface,
Formed on the outer periphery of the upper surface, and includes a plurality of grooves that are arranged at intervals in the circumferential direction of the rotating disk and that can receive the granular materials one by one;
The granular materials received in the grooves are arranged along the circumferential direction of the rotating disk and form a row that moves in the circumferential direction of the rotating disk as the rotating disk rotates, and each groove is directed radially outward of the rotating disk. An alignment device having a shape that allows the granular material received in
A discharge device for discharging the row of granular materials from a rotating disk,
A discharge position defined on the outer peripheral edge of the rotating disk;
A discharge guide for deflecting the moving direction of the row of granular materials at the discharge position outward in the radial direction of the rotating disk,
The discharge guide extends from the discharge position across the outer periphery of the rotating disk toward the radially outer side of the rotating disk, and defines a guide passage that guides the row of the granular materials.
The guide passage has a guide surface facing the radially outer side of the rotating disk, and the guide surface removes the granular material in the groove in the radially outer side of the rotating disk in a region from the discharge position to the outer periphery of the rotating disk. And a discharge device that pushes out toward the groove and pulls out from the groove.

According to the above-mentioned feeder, the granular material supplied onto the rotating disk is received by the individual grooves using the inclination of the upper surface, and one row of granular objects is formed on the rotating disk. Such a row of granular materials is moved in the circumferential direction of the rotating disk as the rotating disk rotates.
After that, after the row of granular materials reaches the discharge position, the discharge guide, that is, the guide surface pushes out the granular materials forming the row and pulls out from the groove toward the radially outer side of the rotating disk. As a result, the moving direction of the row is deflected from the circumferential direction of the rotating disk and guided into the grain guide passage. Thereafter, the row of granular materials is supplied to the subsequent apparatus through the guide passage.

Each groove has an axis extending along the radial direction of the rotating disk, and this axis determines the direction in which the granular material comes out of the groove.
The axis of each groove is inclined so that the end of the groove located on the outer peripheral side of the rotating disk is shifted in the direction opposite to the rotating direction of the rotating disk. For example, the axis of the groove positioned at the discharge position is inclined at a predetermined clearance angle with respect to the normal line orthogonal to the guide surface.
If the axis of the groove and the guide surface are in the above relationship, when the groove moves from the discharge position to the rotation direction of the rotary disk as the rotary disk rotates, the pushing direction of the granular material by the guide surface is the axis of the groove. The particulate matter smoothly exits from the groove.

The exit direction of the particulate matter from the groove does not necessarily coincide with the direction of the axis of the groove, and may be inclined upward or downward with a predetermined exit angle with respect to this axis.
Furthermore, this invention also provides the supply method of a granular material.

The granular material feeder and its supply method of the present invention form a line in which the granular material is arranged in a line on the rotating disk without breaking the granular material, and thereafter stably supply the line of the granular material from the rotating disk. To do.
Other objects and advantages of the present invention will become apparent from the accompanying drawings and the following description of the modes for carrying out the invention.

It is a longitudinal cross-sectional view of the groove | channel of FIG. It is a figure for demonstrating the air assist for a discharge guide.

Referring to FIG. 1, there is schematically shown a composite filter rod manufacturing system to which a granular material feeder and its supply method of the present invention are applied. Before describing the feeder and the supply method, the manufacturing system will be briefly described below.
The production system includes a horizontal production line 12 that includes an upstream conveyor 14 and a downstream conveyor 16. The upstream conveyor 14 supplies a composite element row in which the filter elements Fpe and Fce are alternately arranged toward the downstream conveyor 16.

The filter element Fpe is obtained by cutting the filter rod Fp in the process in which the filter rod Fp taken out from the hopper 18 is transferred to the upstream conveyor 14. Similarly, the filter element Fce is obtained by cutting the filter rod Fc in the process in which the filter rod Fc taken out from the hopper 20 is transferred to the upstream conveyor 14. The filter rod Fp includes an acetate fiber tow material and a web that wraps the tow material in a rod shape. On the other hand, the filter rod Fc differs from the filter rod Fp only in that it contains activated carbon particles distributed in the tow material.

Further, a spacer drum 22 is disposed at the end of the upstream conveyor 14. When the element row passes through the spacer drum 22, the spacer drum 22 adjusts the space between the filter elements Fpe and Fce forming the element row to be constant.
Thereafter, the element row is transferred from the upstream conveyor 14 onto the downstream conveyor 16 via the paper web W. That is, the element row is transported together with the paper web W onto the downstream conveyor 16 toward the subsequent wrapping section 24. The paper web W is supplied to the downstream conveyor 16 from a roll (not shown).

On the other hand, a feeder 26 for supplying granular materials, for example, beads, is disposed immediately above the downstream conveyor 16. In the case of the present embodiment, the feeder 26 includes two

distributors

28 and 30. These

distributors

28 and 30 have the same structure and are arranged side by side along the downstream conveyor 16.
The upstream distribution 28 supplies beads B to every other space in the element row, while the downstream distributor 30 supplies beads B to the remaining space. Therefore, when an element row is supplied to the wrapping section 24, the element row is formed into a composite element row in which beads B are distributed in all its spaces.

Here, the beads B are, for example, spherical capsules containing a liquid fragrance, and have a diameter of about 3 to 5 mm, for example.
The

distributors

28 and 30 will be described later.

The wrapping section 24 receives the composite element array and the paper web W, and wraps the composite element array continuously with the paper web W using a garnish tape (not shown), as is known, thereby providing a composite filter rod continuum C. Mold.
After this, the continuum C is delivered from the wrapping section 24 and passes through the cutting section 32. The cutting section 32 cuts the continuous body C at a predetermined length to manufacture a composite filter rod FR. The composite filter rod FR has a length that is a multiple of the filter F used in one of the filter cigarettes.

More specifically, the continuous body C of the composite filter rod FR is cut at the center of the filter element Fce, and each composite filter rod FR has a half body Fceh of the filter element Fce at both ends as is apparent from FIG. The composite filter rod FR is supplied to a filter mounting machine (not shown) and used for manufacturing a filter cigarette. That is, the composite filter rod FR is further cut into a plurality of double filters DF.

The double filter DF includes a half Fceh of the filter element Fce at both ends thereof, and a bead B disposed between the filter element Fpe and the filter element Fpe and each half Fceh at the center. Such a double filter DF forms a double filter cigarette together with two cigarettes by wrapping chip paper as is well known, and then the double filter cigarette is cut into individual filter cigarettes.

Next, the

distributors

28 and 30 will be described in detail.
Since the

distributors

28 and 30 have the same structure, only the distributor 28 will be described below with reference to FIG.

2, the distributor 28 includes a feeder 34, and the feeder 34 is disposed above the downstream conveyor 16. As will become clear from the following description, the feeder 34 discharges the beads B in a row. The discharged beads B are guided into a supply hose 36 having an antistatic function and transferred through the supply hose 36.

The supply hose 36 extends straight downward from the feeder 34, and the beads B in the supply hose 36 are stacked in a line. An upper level sensor 38 and a lower level sensor 40 are disposed outside the supply hose 36. These

level sensors

38 and 40 detect the bead B in the supply hose 36 and output a detection signal. The detection signal here is used to control the supply of beads B from the feeder 34 to the supply hose 36. Therefore, the filling height of the beads B in the supply hose 36 is always maintained at the level position between the upper level sensor 38 and the lower level sensor 40.

A distribution unit 42 is disposed immediately above the downstream conveyor 16, and the distribution unit 42 includes a fixed plate 44 and a circular rotating plate 46. The fixed plate 44 and the rotating plate 46 have inner surfaces that face each other. The fixed plate 44 has a spiral groove 48 on its inner surface. The spiral groove 48 is formed around the rotation shaft 50 of the rotary plate 46 and has an outer end that opens downward just above the downstream conveyor 16.

On the other hand, the rotating plate 46 has a large number of radiating grooves 52 on its inner surface, and these radiating grooves 52 extend from the rotating shaft 50 to the outer periphery of the rotating plate 46. Immediately before the rotating plate 46 rotates and the inner end of one radiating groove 52 passes through the inner end of the spiral groove 48, the inner end of the radiating groove 52 communicates with a guide passage (not shown) that penetrates the fixed plate 44. The beads B are supplied through this guide passage. That is, the guide passage is connected to the lower end of the supply hose 36 described above.

After the beads B are supplied to the inner end of the radiation groove 52 in this way, when the rotation of the rotating plate 46 proceeds, the beads B are sandwiched between the radiation groove 52 and the spiral groove 48. Thereafter, as the rotation of the rotating plate 46 further proceeds, the radiation groove 52 that has been supplied with the beads B cooperates with the spiral groove 48, and the beads B are directed toward the outer periphery of the rotating plate 46 according to the spiral shape of the groove 48. And is supplied to one space of the element row on the downstream conveyor 16 by its own weight from the outer end of the spiral groove 48. Here, it goes without saying that the peripheral speed of the rotating plate 46 matches the transfer speed of the element row.

Furthermore, the distribution unit 42 includes a bead detection sensor 54. The bead detection sensor 54 is disposed below the fixed plate 44, detects the bead B in the radiation groove 52 passing through the bead detection sensor 54, and outputs the detection signal. When the beads B are present in all of the radiation grooves 52 that pass through the bead detection sensor 54, the bead detection sensor 54 outputs a continuous signal and generates a pulse waveform with a constant pitch.

However, when there is an empty radiation groove 52, a missing pulse appears in the pulse waveform. Such missing pulses are useful for identifying defective filter rods FD with missing beads B and then removing the defective filter rods FD from the production line.

Next, the feeder 34 according to an embodiment will be described with reference to FIGS.
The feeder 34 includes a rotating disk 56. The rotating disk 56 is formed with a predetermined angle α (for example, 5 to 20 °) with respect to a horizontal plane. That is, the rotating disk 56 has an upper surface 58 that is inclined with respect to a horizontal plane.

A supply cone 60 is arranged at the center of the upper surface 58, and the supply cone 60 can rotate independently of the rotating disk 56. That is, the rotating disk 56 has a hollow rotating shaft 62, while the rotating shaft 64 of the supply cone 60 passes through the rotating disk 56 and extends through the rotating shaft 62. These

rotary shafts

62 and 64 are connected to separate

drive sources

66 and 68.
The outer periphery of the rotating disk 56 is surrounded by a surrounding member 70, and this surrounding member 70 is fixed to a base (not shown).

A hopper 72 is disposed above the supply cone 60. The hopper 72 stores a large number of beads B therein and has an outlet 74 that opens toward the supply cone 60. As apparent from FIG. 3, the outlet 74 is disposed between the outer peripheral edge of the supply cone 60 positioned below and the apex of the supply cone 60 as viewed in the circumferential direction of the supply cone 60, and is parallel to the upper surface 58. It has an opening edge 76. Accordingly, the clearance between the opening edge 76 and the supply cone 60 increases as the distance from the apex of the supply cone 60 increases.

When the feed cone 60 is stopped rotating, a bead B bridge is formed between the outlet 74 of the hopper 72 and the feed cone 60, and such a bridge prevents the release of the bead B from the outlet 74. . However, when the supply cone 60 is rotated in one direction, for example, counterclockwise CC as indicated by the arrow in FIG. 4, the rotation of the supply cone 60 eliminates the bridge described above and allows the release of beads B from the outlet 74. To do.

The beads B discharged from the outlet 74 are guided onto the upper surface 58 of the rotating disk 56 while rolling on the supply cone 60. As described above, since the upper surface 58 is inclined with respect to the horizontal plane and the surrounding member 70 is disposed outside the rotating disk 56, the beads B are located in the lower region of the rotating disk 56, that is, in the collecting region G. Collect along the outer periphery of the upper surface 58.

On the other hand, the feeder 34 further includes an alignment device, and this alignment device forms one bead array on the upper surface 58 of the rotating disk 56. In other words, the alignment device includes a plurality of grooves 78, which are formed on the outer peripheral edge of the upper surface 58 and are arranged at intervals in the circumferential direction of the rotating disk 56. The groove 78 has a size capable of receiving the beads B one by one.

Therefore, when the rotating disk 56 is rotated in the counterclockwise direction CC as seen in FIG. 4 and each groove 78 passes through the collecting area G of the beads B described above, each groove 78 receives one bead B in the collecting area G. be able to. Therefore, the grooves 78 that have passed through the collecting region G receive the beads B in all of them, and form one bead row R. Such a bead array R is moved in the counterclockwise direction CC of the rotating disk 56 along the circumferential direction of the rotating disk 56.

In order to ensure stable formation of the bead row R, a remaining amount detection sensor 80 is disposed above the collecting area G, and this remaining amount detection sensor 80 detects the amount of beads B remaining in the collecting area G. And output a remaining amount signal. Such a remaining amount signal is used to control the rotation of the supply cone 60 and appropriately maintains the remaining amount of the beads B in the collecting area G.

In this way, if the remaining amount of beads B in the gathering area G is properly maintained, the beads B in the gathering area G will not be excessively deposited. Will not be lifted up. As a result, the beads B in the collecting area G are quickly received by the grooves 78 passing through the collecting area G even if the rotational speed of the rotating disk 56 is increased, and a stable bead array R can be formed. .

Further, each groove 78 allows the received beads B to be pulled out radially outward of the rotating disk. For example, in the case of the present embodiment, as is clear from FIG. 5, each groove 78 has an axis line along the radial direction of the rotating disk 56, and has an open end opened at the outer periphery of the rotating disk 56. That is, the opening edge of each groove 78 has a U-shape that is open at the outer periphery of the rotating disk 56 when viewed from above, while each groove 78 also has a U-shape when viewed in cross section. .

Further, the depth of each groove 78 is shorter than the diameter of the bead B, and therefore, a part of the bead B in the groove 78 protrudes from the upper surface of the rotating disk 56. Further, in the illustrated embodiment, the bottom of each groove 78 is parallel to the upper surface 58 of the rotating disk 56. However, the bottom of each groove 78 may have, for example, an upward gradient toward the opening end of the groove 78, that is, a slip-out angle Θ1 (see FIG. 5). Selected from the range of ° C.

On the other hand, the feeder 34 further includes a discharge device, which discharges the bead row R from the rotary disk 56 at the discharge position E of the rotary disk 56. As shown in FIG. 4, the discharge position E is positioned above the horizontal plane that is separated from the above-described remaining amount detection sensor 80 in the diameter direction of the rotary disk 56 and includes the rotation center of the rotary disk 56.

The discharge device includes a discharge guide 82, and the discharge guide 82 extends from the discharge position E to the outer periphery of the rotating disk 56, that is, across the enclosure member 70 and radially outward of the rotating disk 56. Here, the extending direction of the discharge guide 82 is preferably parallel to the tangential direction with respect to the rotating disk 56 at the discharge position E, for example.

For example, the discharge guide 82 has two plate members extending in parallel with each other, and these plate members extend along the upper surface 58 immediately above the rotary disk 56. The two plate members cooperate to define a guide passage 84, and the width of the guide passage 84 is set so as to maintain the row state of the bead row R described above.

As shown in FIG. 6, for example, the guide passage 84 has an inner end 86 positioned at the discharge position E and an outer end 88 positioned outside the rotating disk 56, and the outer end 88 is described above. It is connected to a supply hose 36 (see FIG. 2).

The inner end 86 opens in a direction facing the rotational direction CC of the rotary disk 56, and when the beads B forming the bead row R reach the discharge position E, the beads B are received. Guided inside. That is, the moving direction of the bead row R is deflected from the circumferential direction of the rotating disk 56 to the extending direction of the guide passage 84 at the discharge position E. Thereafter, the bead row R is guided into the supply hose 36 from the guide passage 84 and supplied to the distribution unit 42 through the supply hose 36. Needless to say, the portion of the guide passage 84 located outside the rotating disk 56 has a bottom.

The deflection of the bead array R at the discharge position E will be described in detail below.
The guide passage 84 has a guide surface 90, and the guide surface 90 is formed by an inner surface of a plate member positioned on the inner side in the radial direction of the rotating disk 56, and faces the outer side in the radial direction of the rotating disk 56. When a normal line orthogonal to the guide surface 90 is considered, the axis of the groove 78 at the discharge position E is inclined with a predetermined clearance angle Θ2 with respect to the normal line.

In this regard, in FIG. 7, the axis and normal of the groove 78 are indicated by reference signs A and N, respectively. Here, as described above, if the guide passage 84, that is, the guide surface 90 extends in parallel to the tangential direction at the discharge position E, the direction of the normal N is the discharge position E and the rotation center of the rotary disk 56. Coincides with the line segment of the rotating disk 56 connecting the two.

As apparent from FIG. 7, the axis A of the groove 78 is inclined with respect to the normal N, and the opening end of the groove 78 is opposite to the rotational direction CC of the rotating disk 56 than the closed inner end of the groove 78. Has been shifted to. Therefore, the angle formed by the axis A and the normal N, that is, the clearance angle Θ2, is selected from the range of 0 to 30 °, for example.

At the discharge position E, when the beads B forming the bead row R are positioned at the inner end 86 of the guide passage 84 or thereafter, when the rotation of the rotating disk 56 further proceeds, the beads B are rotated at the rotating disk 56. The guide surface 90 is brought into contact with a portion projecting from the upper surface 58.
As described above, since the discharge position E is disposed above the horizontal plane including the rotation center of the rotary disk 56, the opening end of the groove 78 at the discharge position E faces upward.

Therefore, when the groove 78 is positioned at the discharge position E, the bead B in the groove 78 is positioned in the groove 78 on the closed inner end side. Therefore, as is apparent from FIGS. 6 and 7, the guide surface 90 contacts the bead B from below.
When the rotation of the rotating disk 56 further proceeds from this state, the guide surface 90 pushes the beads B toward the radially outer side of the rotating disk 56, that is, toward the opening end of the groove 78. Such extrusion of the beads B is continued until the guide surface 90 crosses the outer periphery of the rotating disk 56 (see FIG. 6).

As described above, the clearance angle Θ2 described above is secured between the axis A and the normal line N of the groove 78, so that the rotating disk 56 advances in the pushing direction of the beads B applied from the guide surface 90. Accordingly, it changes toward the axis A of the groove 78. Therefore, an excessive force is not applied to the bead B from the inner surface of the groove 78, and the bead B can be smoothly removed from the groove 78 without breaking. As a result, the above-described discharge guide 82 can stably and continuously discharge the bead array R from the rotating disk 56.

On the other hand, if the axis A of the groove 78 is inclined in the direction opposite to the normal N as shown in FIG. 8, the pushing direction of the bead B applied from the guide surface 90 is the opening end of the groove 78. Instead, it is directed to the inner surface of the groove 78, that is, the inner surface of the groove 78 located on the rear side in the rotational direction CC of the rotary disk 56. Therefore, the pushing direction in this case works so as to sandwich the bead B between the inner surface of the groove 78 and the guide surface 90, and the bead B is also crushed.

The present invention is not limited to the above-described embodiment, and various modifications can be made.
For example, the groove 78 shown in FIG. 9 has a tapered droplet shape toward the outer periphery of the rotating disk 56 when viewed from above. That is, the groove 78 of FIG. 9 has a closed opening edge. In this case, as shown in FIG. 10, the bottom of the groove 78 has a part (solid line) on the outer peripheral side of the rotary disk 56 or the whole (two-dot chain line) inclined with respect to the axis of the groove 78 at an exit angle Θ1. Yes. Such a groove 78 also allows the received beads B to come out toward the outer periphery of the rotating disk 56.

9 and 10, the bead array R is similarly stably formed on the rotating disk 56 and can be smoothly discharged from the rotating disk 56.
The bottom of the groove 78 described above is inclined upward, but may be inclined downward, and the exit angle Θ1 in this case is also selected from the above range.
Further, the discharging device described above can include air assist, which has a nozzle hole 92 as shown in FIG. The nozzle hole 92 is formed in the discharge guide 82 and opens toward the downstream side of the guide passage 84 on the inner surface of the guide passage 84 facing the guide surface 90.

On the other hand, the nozzle hole 92 is connected to a compressed air source 96 through an air supply path 94, and an electromagnetic valve 98 is disposed in the air supply path 94.
According to the air assist described above, when the electromagnetic valve 98 is opened, compressed air is supplied from the compressed air source 96 to the nozzle hole 92 through the air supply path 94, and compressed air is supplied from the nozzle hole 92 to the guide passage 84. Is done. Such compressed air facilitates the supply of the bead row R from the guide passage 84 to the supply hose 36.

In the case of the above-described embodiment, a part of the bead B protrudes upward from the groove 78, but the portion of the guide surface 90 extending from the discharge position E to the outer periphery of the rotating disk 56 is disposed in the rotating disk 56. In this case, the bead B does not need to protrude upward from the groove 78. In this case, a circumferential groove is formed on the outer periphery of the rotating disk 56, and this circumferential groove allows the portion of the guide surface 90 to enter.
Furthermore, the feeder of the present invention is not limited to beads including a material for a composite filter rod, but can be applied to supply of various granular materials that are fragile.
