DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aligning apparatus and an aligning method for aligning an elongated rod.

[0002]

BACKGROUND OF THE INVENTION In recent years, as foods such as bar-shaped snacks, a number of bar-shaped products filled in a cylindrical container in a vertical position have been sold. It is important to align the rods because the filling efficiency of the rods varies significantly depending on the alignment. In other words, by improving the alignment,
Many small rods can be filled in a small container.

Accordingly, it is an object of the present invention to provide an aligning apparatus and a method capable of improving the efficiency of filling a container by improving the alignment of rods.

[0004]

In order to achieve the above object, the present invention relates to an aligning device for aligning a loaded bar in a vertical position, comprising an upper cylindrical portion and a first lower portion below the upper cylindrical portion.
An upper alignment chamber formed by a shutter, and a lower alignment chamber formed by a lower cylinder portion and a second shutter below the lower cylinder portion, and the two alignment chambers are arranged vertically close to or connected to each other; In each of the alignment chambers, the rod-shaped object is caused to swing in a direction including a horizontal component.

In the present invention, after the upper alignment chamber is repeatedly rocked to swing the bar in the horizontal direction, the first shutter is opened and the bar is dropped into the lower alignment chamber. Subsequently, the lower alignment chamber is repeatedly swung to swing the bar again in the lateral direction to increase the density of the bar, and then the second shutter is opened to drop the bar into the lower packaging material.

In the present invention, the "vertical posture" refers to a posture in which the axis (longitudinal direction) of the rod-like object is substantially along a vertical line or a posture slightly inclined from this posture.

[0007] The term "direction including a horizontal component" means that, in addition to swinging in the horizontal direction, swinging may be performed slightly obliquely or may be caused to swing along a flat elliptical orbit. Means

In the present invention, in the loading chamber near or above the upper end of the upper alignment chamber, the rods falling in a horizontal or oblique posture are brought into contact with the side surfaces of the rods, and the rods in these postures are rotated vertically. It is preferable to provide a posture control unit that changes or brings the posture closer to the posture. Here, the “horizontal posture” refers to a posture in which the axis (longitudinal direction) of the rod-like object is substantially along a horizontal line, or a posture in which the axis is slightly inclined from this posture. Further, the “diagonal posture” refers to an intermediate position between the “horizontal posture” and the “vertical posture”.

The "posture control section" is preferably formed of an elongated member such as a bar, but can also be formed by the upper end face of a partition wall standing upright along a vertical plane.

In the present invention, it is preferable that at least the upper alignment chamber of the upper and lower alignment chambers is provided with a partition wall for dividing the upper alignment chamber into a plurality of sections in the lateral direction. Since the small chamber divided by the partition wall has a small cross-sectional area, it is possible to prevent the rod-shaped object from falling down due to swinging, and the rod-shaped object receives a lateral force from the partition wall, so that the alignment action is enhanced.

In a preferred embodiment of the present invention, a charging chamber for receiving a rod-shaped object is provided adjacent to or connected to the upper alignment chamber, and a rod-shaped chamber extending from an upper end of the charging chamber to a lower end of the lower alignment chamber. The cross-sectional shape of the falling path of the object alternately changes at two or more places between a circle and a rectangle. In a group of rods (bundles) arranged to some extent, some of the rods may be in two stages in the room. In such a case,
When the cross-sectional shape of the falling path was changed, immediately after the group of rods fell into the lower chamber, there was a gap between the rods enough for other rods to enter, so that there were two stages. This is because the object falls into the gap and becomes one stage.

Also, in the present invention, after a lapse of a predetermined time after the rod-like material is discharged toward the upper alignment chamber,
It is preferable that the swing be given to the upper alignment chamber.

In a preferred embodiment of the present invention, a hopper is provided above the upper alignment chamber to open and close the gate and drop a bar-like object, and a horizontal component in the opening and closing direction of the gate and the swing The horizontal component of the direction is set to a direction substantially orthogonal to the horizontal component.

On the other hand, the method of the present invention is an alignment method for aligning the inserted rods in a vertical position, wherein the rods are rocked in a vertical path while swinging in a fall path in which the outer periphery is covered. Along with aligning, the cross-sectional area of the fall path is different from each other at the upper and lower positions of the fall path,
The density of the rod is increased.

In a portion where the cross-sectional area of the falling path is small, the gap between the rods is narrowed by the swinging, and the density of the rods is increased. On the other hand, in the part where the cross-sectional area of the falling path is large, immediately after the rods aligned to a certain extent fall into the lower chamber, there is a gap between the rods that allows the rods to be inserted. May fall into the gap and become one stage.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, a weighing / discharging device A such as a combination weighing device is disposed above the aligning device B, while a transport device C is disposed below the aligning device B. The weighing and discharging device A is a discharge hopper (timing hopper) that opens and closes a food bar M such as a snack as shown by an arrow X1 in FIG.
Drop from 200 and discharge. This discharge hopper 200
In general, most of the posture of the rod-shaped material M falling from the side is a horizontal posture or an oblique posture. The alignment device B of FIG.
After aligning the inserted rods in the vertical position, the outlet 4c
Drain from below. The transport device C transports, for example, a tapered cylindrical container (wrapping material) W directly below the discharge port 4c, and when the rod W is filled in the container W, transfers the container W to the next step. I do.

The aligning device B has a swinging device 100. The oscillating device 100 reciprocates the oscillating portion 1 in the arrow Y direction by rotating an eccentric plate by rotation of a motor (not shown), for example. The oscillating portion 1 is provided with a gantry 10.
1 is provided on a swing frame 1 so as to be swingable in an arrow Y direction.
02.

As shown in FIG. 2, the oscillating portion 1 includes a charging chamber 2, an upper alignment chamber 3 and a lower alignment chamber 4 in this order from above. These three chambers 2 to 4 are provided immediately below the discharge hopper 200 and are provided close to each other or connected to each other. The tapered cylindrical body 20 forming the charging chamber 2 and the upper inner cylindrical portion (upper cylindrical portion) 30 forming the upper alignment chamber 3 are flanged to each other. The lower inner cylindrical portion (lower cylindrical portion) 40 forming the lower alignment chamber 4 and the upper inner cylindrical portion 30 are joined to each other via an outer cylindrical body 50. The outer cylinder 50 is fixed to the swing frame 102 (FIG. 1) via a bracket 51 or the like. Therefore, the three chambers 2 to 4 are simultaneously swung in the Y direction in FIG.

In FIG. 3, the upper alignment chamber 3 is formed by the upper inner cylindrical portion 30 and a pair of first shutters 31 below the upper inner cylindrical portion 30. On the other hand, the lower alignment chamber 4 is formed by the lower inner cylindrical portion 40 and a pair of second shutters 41 below the lower inner cylindrical portion 40. The first and second shutters 31 and 41 are plate-shaped, and are individually opened and closed in the arrow X direction by a pair of first and second switches 32 and 42 shown in FIG. Each of the switches 32 and 42 is formed of, for example, an air cylinder. The outer cylinder 50 has an insertion hole 52 into which the first shutter 31 is inserted. In FIG. 3, the first shutter 31 is shown in an exploded direction of arrow X in order to make the structure of the lower alignment chamber 4 easy to understand.

The three chambers 2 to 4 constitute a falling path of the present invention. Hereinafter, a detailed structure of the three chambers 2 to 4 will be described.

The charging chamber 2 is formed by a tapered cylindrical body 20 into a truncated conical shape tapering downward. In the upper part of the charging chamber 2, there is provided a first attitude control unit composed of rods (elongated members) 21, 21 such as two round bars. These rods 21 hit the side surfaces of the rods M falling in a horizontal posture or an oblique posture, and as shown in FIG. 4, rotate the rods M in the above posture to change or approach the posture to the vertical posture. .

The two bars 21 shown in FIG. 3 are laid in a cross shape in the radial direction (radial direction) of the charging chamber 2. Thereby, it comes into contact with the rod-shaped material M falling to various falling positions.

The two rods 21 are inclined obliquely downward as they approach the center of the charging chamber 2 in the radial direction. By disposing the bar 21 in an inclined state in this manner, the occurrence of the bridge of the bar-shaped material M on the bar 21 is suppressed as described below. That is, as shown in FIG. 3, when the bar-shaped material M falls across the two bar-shaped materials 21 and the bar-shaped material 21 is provided horizontally, the bar-shaped material M is placed on the bar-shaped material 21. The bridge is generated with M still on. On the other hand, when the bar 21 is inclined toward the center, the bar-shaped object M that has fallen over the two bars 21 is obliquely located at the center 2 as shown by the arrow Z.
2, so as to roll to the intersection 22 of the two bars 21 or at the intersection 22 of the two bars 21.
And falls at the intersection 22 or the like so as to approach a vertical position. Therefore, a bridge is less likely to occur.

The tapered cylindrical body 20 is provided with four slits 23 which are long in the vertical direction. Each of the bars 21 is
The vertical position can be freely set along the slit 23. Thus, the vertical position of the bar 21 can be set according to the shape and properties of the falling bar M. Both ends 24 of the bar 21 are fixed to the tapered cylindrical body 20 by brackets and nuts (not shown).

The discharge hopper 200 shown in FIG. 2 comprises a pair of gates 201, and is tapered so that the rod-shaped material M can be easily aligned in a posture close to a horizontal posture. The horizontal component X in the opening / closing direction X1 of the discharge hopper 200 and the swing direction Y in FIG. 3 are set to directions substantially orthogonal to each other. With this direction setting, as described below, the occurrence of bridges on the bar 21 is suppressed. That is, when vibration is applied to the rod M shown by the two-dot chain line in FIG. 3 in the X direction, that is, when the rod M is repeatedly rocked in the radial direction of the rod M, the rod M To reciprocate in the X direction (the bar-shaped material M dances on the bar 21), and it becomes easy to maintain the lateral posture without falling. On the other hand, when the bar M is vibrated in the Y direction, that is, when the bar M is repeatedly rocked in the longitudinal direction (axial direction) of the bar M, the bar M is moved with respect to the loading chamber 2 in the Y direction. , The rod-shaped material M easily falls downward so as to rotate around the rod 21. Therefore, a bridge is less likely to occur.

From the vicinity of the upper end of the upper alignment chamber 3 to the lower part of the lower alignment chamber 4, first and second partitions for partitioning each alignment chamber into four small chambers 3a, 4a in the horizontal direction (X, Y directions). Plates (partition walls) 11 and 12 are provided. These partitions 11,
12 is provided in the upper alignment chamber 3 in the radial direction, so that the upper end surfaces of the partition plates 11 and 12
Is composed. The partition plates 11 and 12 are provided at positions where the plane position is displaced from the bar 21 by about 45 °, thereby increasing the posture control function. That is, a part or most of the rod-shaped material M falls into the lower upper alignment chamber 3 in an oblique posture or a vertical posture due to the rod material 21 of the upper charging chamber 2, but the posture is sufficiently controlled. The rod-shaped material M that has not fallen downward from between the rods 21 and 21. Such a rod-shaped material M is formed by the rods 21 and
1 and a bar-shaped object M
When the side of the abutment comes into contact, it rotates and approaches a vertical posture. The attitude control unit 13 is also inclined downward as it approaches the center of the upper alignment chamber 3 in the radial direction.

As shown in FIG. 4, each of the small chambers 3a, 4a
Is a vertically long shape having a small cross-sectional area, so that when the rod-shaped material M that has fallen from the charging chamber 2 in the vertical posture or the oblique posture is received, the rod-shaped material M does not assume the horizontal posture, The length L of the bottom of each of the small chambers 3a, 4a is set so that the rod-shaped material M does not assume the horizontal posture while the rocking member is swinging.
Is preferably set to be shorter than the length. In addition, the small chambers 3a of the upper alignment chamber 3 have a height H in each small chamber 3a that can sufficiently accommodate the bar-shaped objects M even if they are vertically arranged in two stages.

As described above, each of the divided small chambers 3
The rod-shaped material M is swung in the horizontal direction Y in the insides a and 4a, so that not only the upper inner cylinder 30 and the lower inner cylinder 40 but also
Since the side surfaces of the rod-shaped material M also abut against the two partition plates 11 and 12 which are erected in the vertical direction, the alignment effect is enhanced.

As shown in FIG. 3, the cross-sectional shape of the upper alignment chamber 3 is substantially square, and has a size circumscribing the circle at the lower end of the charging chamber 2. Therefore, the cross section of the falling path changes from a circle to a square, and the cross-sectional area is slightly larger in the upper alignment chamber 3. With such a shape and size, a gap S is generated between the rods M while the rod M is being swung in the upper alignment chamber 3 in FIG. Another upper bar M enters the gap S. Therefore, part or all of the bar M in the upper and lower two stages can be reduced to one stage.

As clearly shown in FIG. 3, the upper inner cylindrical portion 30
A slit 33 for the first shutter 31 to enter is provided between the lower inner cylinder 40 and the lower inner cylinder 40. Further, the slit 1 for allowing the first shutter 31 to enter the partition plate 12 is also provided.
4 are provided. The partition plate 11 extends from the upper alignment chamber 3 to the upper part of the lower alignment chamber 4.

As shown in FIG. 4, both partition plates 11 and 12 are provided above the lower alignment chamber 4, but both partition plates 11 and 12 are provided below the lower alignment chamber 4. Not. That is, both partition plates 11,
An assembly room 4b in which no 12 is provided is formed.
As shown in FIG. 3, the lower inner cylindrical portion 40 has a rectangular cylindrical shape at the upper part and a hopper shape at the lower part, that is, a tapered cylindrical shape, and is gradually narrowed toward the lower end. FIG.
Is formed to be higher than the length Lm of the rod-shaped material M.

Since the collecting chamber 4b is constricted downward as described above, the gap between the rods M, M becomes smaller as the rods M fall down, so that the density (filling) is reduced. Efficiency). Further, since the collecting chamber 4b is narrowed downward, the upper gap S1 between the rods M, M becomes large.
Enters. Therefore, in the collecting room 4b,
By applying vibration to the rod-shaped material M, it is possible to eliminate the upper and lower two-stage state and increase the density.

Next, the timing of opening and closing and swinging of the upper and lower shutters 31, 41 will be described. As shown in FIG. 5, the upper gate 201 opens while the first shutter 31 is closed. On the other hand, the lower second shutter 41
When the is closed, the first shutter 31 is opened. In addition, while the upper first shutter 31 is open, the entire swinging portion 1 is swung (vibrated) by the alignment device B, but at the same time as the first shutter 31 closes, the swinging portion 1 swings. To stop. Further, after a predetermined minute time ΔT after the discharge from the gate 201 is started, the swinging portion 1 starts swinging. The reason why the swing of the swingable portion 1 is delayed by the minute time ΔT is to suppress the occurrence of a bridge in the charging chamber 2 in FIG. That is, when the charging chamber 2 is vibrated immediately after the rod-shaped material M is dropped and discharged from the discharge hopper 200 (FIG. 2), the rod-shaped material M does not immediately fall downward, and the rod-shaped material M dances on the rod 21. As a result, a bridge is likely to be generated, so that the oscillation of the oscillating portion 1 starts after a predetermined minute time ΔT after dropping and discharging from the discharge hopper 200 (FIG. 2).
The drive timing of each device is controlled by a control device.

Next, the rod-shaped material M using the alignment device B
Will be described. Discharge hopper 200 of FIG.
When the first shutter 31 is closed in a state where a certain amount of the rod-shaped material M is supplied into the inside, the gate 201 is opened as shown by a dashed line, and most of the rod-shaped material M is in the horizontal posture or the oblique posture, and the input chamber 2 is set. It falls into the inside. The inserted rod-shaped material M
As shown in FIG. 4, the side surface rotates against the rod 21 and moves toward the lower upper alignment chamber 3 while approaching the vertical position. Further, the posture of the rods M is also controlled by the posture control unit 13 at the upper end of the partition plates 11 and 12, so that all the rods M have a vertical posture or an oblique posture close to the vertical posture, and the upper alignment chamber 3 Falls into the small chamber 3a.

When the rod-shaped material M falls into each of the small chambers 3a of the upper alignment chamber 3, the oscillating portion 1 is repeatedly oscillated in the horizontal direction Y, whereby the posture of the rod-shaped material M approaches the vertical posture. As shown in FIG. 3, the cross section of the falling path changes from a circle to a rectangle as shown in FIG.
Most of the bar-shaped material M, which has been divided into two stages, becomes one stage.

Thereafter, in a state where the first shutter 31 is closed and while applying vibration to the swingable portion 1, the first shutter 31 is opened and the rod-shaped material M of the upper alignment chamber 3 is moved to the lower alignment chamber 4.
To fall. After the dropping, the vibration is once stopped and then vibrated again. Since the lower alignment chamber 4 is constricted downward, the rod-shaped material M is prevented from being in two stages as described above. obtain. Thereafter, the switch 32 is opened, and the rod-shaped material M aligned in the vertical position is dropped into the container W below in FIG.

As described above, the preferred embodiments have been described with reference to the drawings. However, those skilled in the art can easily envisage various changes and modifications within the obvious scope by referring to the present specification. There will be. For example, as shown in FIG. 6A, the elongated member may be formed by bending a sheet metal as the first attitude control unit 21. Further, as shown in FIG. 6B, an elongated member may be formed by a band plate. Further, as shown in FIG. 6C, the end of the attitude control unit 21 may be welded and fixed to the upper inner cylinder 30, and the attitude control unit 21 may be missing at the center. In addition, the attitude control unit 21 may be one.

The shape of the collecting chamber 4b shown in FIG. 3 may correspond to the shape of the container W filled with the rod-shaped material M.
Is a rectangular cylindrical shape, it is preferable that the lower part of the lower inner cylindrical portion 40 be a tapered rectangular cylindrical shape. Further, the tubular portion and the partition wall do not need to be formed of a complete plate, but may be formed of a member such as a mesh. Further, in the above-described embodiment, the notch 120 is formed below the partition plates 11 and 12 in FIG. 2, but the notch 120 does not need to be formed.

The upper inner cylinder 30 and the lower inner cylinder 40 are
It is only necessary to provide a slit 33 that allows the first shutter 31 to open and close, and there may be a side surface that extends vertically like the outer cylinder 50. Further, the partition plates 11 and 12 may not be provided in the lower alignment chamber 4. Further, it is not necessary to swing each of the alignment chambers horizontally, but it is sufficient to swing them in a substantially horizontal direction. In some cases, a vertical component may be added to a horizontal component to swing. Furthermore, each alignment chamber may be rocked by a separate rocking device, and the timing of rocking each alignment chamber is not limited to the above embodiment. Further, the rod-shaped material may be directly charged into the alignment chamber from the hopper of the weighing machine without providing the charging chamber. Accordingly, such changes and modifications are to be construed as being within the scope of the invention as defined by the appended claims.

[0040]

As described above, according to the present invention,
Since the upper alignment chamber and the lower alignment chamber divided into upper and lower chambers are provided and each alignment chamber is repeatedly swung, the density of the bar-like material in the vertical position in each alignment chamber increases, and the Filling efficiency increases.

Further, by providing the attitude control unit, the rod-like object that has fallen in the horizontal or oblique attitude falls while rotating while coming into contact with the attitude control unit. It becomes an oblique posture close to the posture. Therefore, it becomes easy to align.

On the other hand, by dividing the upper alignment chamber into a plurality of small chambers in a lateral direction, the cross-sectional area of each of the small chambers is reduced, so that the rod-shaped objects can be prevented from falling down and each rod-shaped object can be swung from the partition wall. Since the power is received, the density of the rod can be increased.

Also, by alternately changing the cross-sectional shape of the falling path between a circular shape and a rectangular shape, a gap is generated between the rod-shaped objects at the portion where the shape is changed. Things enter. Therefore, the bar-shaped objects can be aligned in a single-stage state, which is not in the upper and lower stages.

Further, by starting the swinging of the upper alignment chamber after a predetermined time after the rod-shaped objects are discharged toward the upper alignment chamber, it is possible to prevent the rod-shaped objects before the posture control from being bridged upward. Become like

Further, by setting the swing direction with respect to the opening and closing direction of the gate, the alignment chamber can be swung in the longitudinal direction of the bar, so that the bar before the posture control is bridged upward. Can be prevented.
