Description of the Related Art An example of the above-mentioned conventional filling apparatus will be described with reference to FIG. 15 (see Japanese Patent Application Laid-Open No. 8-271327). This filling device is for filling a plurality of rod-shaped articles 1 measured and discharged by a conventionally known combination weigher (not shown) into a predetermined container (not shown). A swing guide cylinder 3 that is provided below the exit of the collecting chute 2 and is in contact with the upper side surface of the rod-like article 1 discharged from the collecting chute 2 to hold the rod-like article 1 in an upright state; A vibration mechanism 5 for swinging the moving guide tube 3 around a pivot 4 provided on the collecting chute 2 to align the rod-shaped articles 1 in an upright state, and provided below the swing guide tube 3; A fixed guide tube 6 which is in contact with the lower side surface of the bar-shaped article 1 discharged from the collecting chute 2 and is held in an upright state, and is provided below the fixed guide tube 6 to receive the bar-shaped article 1 and move in the horizontal direction. Bar-shaped articles received by levers A gate 7, 7 for discharging downwards,
It has. The vibration mechanism 5 includes a motor 8, a disk 9 provided on a rotating shaft 10 of the motor 8, and a link having one end connected to the disk 9 at an interval from the rotating shaft 10. 11 and an arm 12 connected to the other end of the link 11 and connected to the swing guide cylinder 3.

According to this filling apparatus, a plurality of bar-shaped articles 1 which are combined and weighed and discharged from an outlet of a collecting chute 2 are arranged.
Is dropped on the gates 7 and 7, and the upper side surface thereof is held by the swing guide tube 3 while standing upright, and the lower side surface thereof is held by the fixed guide tube 6. Then, in this state, the vibration mechanism 5 is driven to swing the swing guide cylinder 3 about the pivot 4 so that the rod-like articles 1a, b in the vertically overlapped state as shown in FIG. The upper bar-shaped article 1a can be dropped on the gates 7,7. In this way,
The rod-shaped articles 1 can be erected and aligned next to each other.

[0004]

However, in the conventional filling apparatus, the lower bar-shaped articles 1a, 1b vertically overlapping on the gates 7, 7 are swung in the left-right direction. The upper bar-shaped article 1a is
The lower rod-shaped article 1b is intended to be dropped, but only by swinging the lower rod-shaped article 1b in the left-right direction, the lower end of the upper rod-shaped article 1a abuts on the upper end of the lower rod-shaped article 1b. In this state, the upper bar-shaped article 1a may follow the lower bar-shaped article 1b and swing. Therefore, there is a problem that the bar-shaped article 1a on the upper side of the bar-shaped articles 1a and 1b that are vertically overlapped cannot be reliably dropped on the gates 7 and 7. Thereby, for example, when filling the rod-shaped articles 1 of a predetermined weight or number into a predetermined container, the rod-shaped articles 1 may overflow from the container, or may be filled in a state of standing next to each other. May not be possible, and the appearance may deteriorate.

In the conventional filling apparatus, for example, when the number of the bar-shaped articles 1 to be filled at one time is large or when the length of the bar-shaped articles 1 is short, the bar-shaped articles 1 fall on the gates 7 and stand up. Since the total lateral width of the plurality of bar-shaped articles 1 is increased, it is necessary to increase the inner diameter of the swing guide cylinder 3 and the fixed guide cylinder 6 according to the total length of the lateral width. However, when the inner diameter of the swing guide tube 3 is increased to a certain value or more, the upper part of the bar-shaped article 1 that rises in an inclined manner on the gates 7 does not reach the inner side surface of the swing guide tube 3 and thus swings. The guide may not be held by the guide tube 3, but may be held in contact with the inner surface of the fixed guide tube 6, or may fall on the gates 7, 7 as it is. In this state, even if the swing guide cylinder 3 is swung, the bar-shaped articles 1 on the gates 7 and 7 cannot be neatly stood up and aligned. , Causing problems such as the bar-shaped article 1 overflowing from the container as described above.

According to the present invention, regardless of the length and the filling amount of the bar-shaped articles, the bar-shaped articles can be neatly stood upright next to each other in the filling hopper, and filled in a container or the like in this aligned state.

According to the charging mechanism 23 configured as described above, when the vibration motor 32 is driven and the rotating shaft 32a rotates in a predetermined direction, the rotating link 58 rotates, and the rotating link 58 rotates. The movement is converted into an elevating movement by the eccentric shaft 59, the vibrating link 60, the driven shaft 61 and the like, so that the elevating part 36 can be vibrated up and down in the direction of the arrow 62. The second gate 22 provided below the elevating unit 36 also vibrates up and down along with the elevating unit 36. Next, the swing of the filling hopper 21 when the elevating unit 36 vibrates up and down will be described. First, as shown in FIG. 1, when the elevating unit 36 moves up from the lowered position and increases speed, the filling hopper 21 swings counterclockwise about the swing shaft 47. The engaged edge portion 49 comes into contact with the right side surface of the groove 51 of the engaging portion 50 shown in FIG. That is, the second main body 3 of the filling hopper 21
Horizontal distance between the axis of the center of gravity G ₂ and the rocking shaft 47 3 is L _1, a counterclockwise direction around the pivot shaft 47 relative to the filling hopper 21 by disposing thus Torque (torque based on inertial force) acts. And the elevating unit 3
When the deceleration 6 is decelerated while moving upward, the second main body 33 of the filling hopper 21 is swung clockwise about the swing shaft 47 so that the engaged edge 49 is shown in FIG. The engagement portion 50 comes into contact with the left side surface of the groove 51, and reaches the ascending position in this state. Then, when the elevating unit 36 moves downward from the ascending position and increases speed, the second main body unit 33 of the filling hopper 21 descends in the state shown in FIG. When the elevating unit 36 moves downward and decelerates, the second main body unit 33 of the filling hopper 21 returns to the state shown in FIG. Thus, the second main body 33 of the filling hopper 21
Repeats the above swing while moving up and down.

Then, as shown in FIG.
A predetermined distance L from the second gate 22 _TwoSeparated from above
Vibrates the filling hopper 21 in the vertical direction.
The filling hopper 21 in the direction of arrow 63
In this way, the swinging can be performed over a horizontal range.
Therefore, the filling hopper is driven by one vibration motor 32.
21 in the vertical direction and the horizontal direction.
Can be vibrated.

Further, when the ascending speed of the filling hopper 21 decreases and the descending speed increases while the plurality of bar-shaped articles 1 are accommodated, the weight of the bar-shaped articles 1 applied to the second gate 22 is reduced. The weight applied to the other bar-shaped articles 1 is relatively small, so that the frictional force between the bar-shaped articles 1 and the second gate 22 and the frictional force at the contact portions between the bar-shaped articles 1 are reduced. At this time, for example,
At the lowered position and in the vicinity thereof, the filling hopper 21 swings to the swinging position shown in FIGS. 1 and 2 to change the speed in the horizontal direction. It can be made to stand on the second gate 22 in parallel. Then, the cup 15 can be filled in a state where the bar-shaped articles 1 are aligned as described above.

Further, the filling hopper 21 by the vibration drive unit
Is lower in speed than the free falling speed of the bar-shaped article 1 stored in the filling hopper 21, so that the filling hopper 21 is lowered and oscillated in the horizontal direction. For example, as shown in FIG. 15, when two bar-shaped articles 1a and 1b are overlapped in the vertical direction while standing,
By lowering the filling hopper 21 at a higher speed than the free falling speed of the bar-shaped articles 1 stored in the filling hopper 21, the respective bar-shaped articles 1a and 1b are
It can be raised from one. Then, by lowering the filling hopper 21 and swinging it horizontally, the filling hopper 21 collides with the bar-shaped article 1, and the upper bar-shaped article 1 a overlapping in the vertical direction is moved to the second gate 2.
2 can be dropped. Thereby, the bar-shaped articles 1 vertically overlapping in the filling hopper 21 can be made to stand on the second gate 22 in a state of being adjacent to each other and in parallel.

The filling hopper 21 is vibrated so that the bar-shaped article 1 supplied to the filling hopper 21 and falling freely collides with the second gate 22 in a state where the filling hopper 21 is moved downward by vibration. That is, as shown in the timing chart of FIG. 14, a predetermined time t ₁ has elapsed since the first gate 20 of the reservoir hopper 19 was opened and the bar-shaped article 1 was supplied to the filling hopper 21, and The bar-shaped article 1 moves to the second gate 2 in a state where
I try to collide with 2. Thereby, the rod-shaped article 1
Is supplied to the filling hopper 21 and the impact when the free-fall collides with the second gate 22 can be reduced, so that the rod-shaped article 1 can be prevented from jumping up due to the collision with the second gate 22. As a result, it is possible to prevent the bar-shaped articles 1 from becoming entangled with each other in the filling hopper 21.

Next, referring to FIG.
Will be described. As shown in FIG. 14, rotation and stop of the turntable 24 are alternately performed, and when the filling mechanism 23 moves to a predetermined supply position and stops, the storage hopper 19
The first gate 20 opens to supply the bar-shaped article 1 into the filling hopper 21 (supply step). Then, the filling hopper 21 to which the bar-shaped article 1 is supplied is continuously driven by the vibration motor 32 and vibrates. This first continuous vibration is continued from the supply position shown in FIG. Until the filling mechanism 23 moves from the position A to the discharging position, the vibration motor 32 alternately drives and stops every 400 ms (t ₂ ), and the filling mechanism 23 moves to the discharging position. When stopped, the intermittent vibration of the filling hopper 21 is stopped. The vibration of the filling hopper 21 until the filling mechanism 23 moves from the supply position to the discharge position and stops is called a first vibration stage. Then, with the charging mechanism 23 stopped at the discharge position, the second gate 22 is stopped.
To open and close the rod-shaped article 1 in the filling hopper 21
(First discharge stage). Then, the filling hopper 21 is vibrated for about 400 ms (second vibration stage),
Thereafter, the second gate 22 is opened and closed again (second discharge stage). Thus, one filling operation by one filling mechanism unit 23 is completed, and the same operation as described above is sequentially repeated so that each cup 15 can be filled with the bar-shaped article 1. Here, the filling cycle of one filling mechanism unit 23 has been described, but the filling cycle of the other eleven filling mechanism units 23 is the same, so detailed description will be omitted.

According to the filling method of the filling cycle as described above, all the bar-shaped articles 1 supplied to the filling hopper 21 can be filled in the cup 15 without fail. In other words, even if the filling hopper 21 containing a large number of the rod-shaped articles 1 is vibrated, the rod-shaped articles 1 are hard to move in the filling hopper 21 and the rod-shaped articles 1 caught in the filling hopper 21 are shaken off. However, most of the rod-shaped articles 1 in the filling hopper 21 are discharged at the first discharge stage, and the filling hopper 21 is vibrated again in a state where a wide space is formed (second vibration stage). ), Filling hopper 2
The rod-shaped article 1 remaining in the hook 1 can be shaken off and reliably ejected (second ejection stage).

Next, the first chute 17 shown in FIG. 5 will be described with reference to FIG. The first chute 17 has a short cylindrical shape, the upper opening edge 17a is parallel to the horizontal plane, and the upper opening is connected to the lower opening of the collecting chute 2 as shown in FIG. The lower opening edge 17b is inclined at an angle of about 45 ° with respect to the horizontal plane, and the lower opening is connected to the upper opening 18a of the second chute 18 as shown in FIG. The first chute 17 is for parallelizing the rod-shaped article 1 sliding down the inside thereof with the sliding direction, and is provided with a guide member 64 parallel to the sliding direction. The guide member 64 is a flat plate, and the first
Parallel to the length direction of the chute 17
The chute 17 is provided perpendicular to the sliding surface 17c. The height of the guide member 64 with respect to the slide surface 17c is higher than the diameter of the rod-shaped article 1. Also, the guide member 64
The height on the inlet side of the first chute 17 is the upper opening edge 1 of the first chute 17.
It is inclined so that it becomes higher from 7a toward the lower opening edge 17b. Thereby, the plurality of rod-shaped articles 1 supplied from the outlet of the collecting chute 2 to the upper opening of the first chute 17 are aligned by the upper edge 64a on the inlet side of the guide member 64 so as to be parallel to the sliding direction. Can be. Then, the bar-shaped articles 1 aligned in this manner can be guided by the guide member 64 in this state and sent to the second chute 18 at the subsequent stage.

Next, the second chute 18 shown in FIG. 5 will be described with reference to FIG. The second chute 18 has a funnel-like shape having a circular cross section orthogonal to the sliding direction of the rod-shaped article 1, and has an upper opening edge 18a of about 45 degrees with respect to a horizontal plane.
The upper opening is connected to the lower opening of the first chute 17. Lower opening edge 18b
Are parallel to the horizontal plane, and the lower opening is connected to the upper opening of the reservoir hopper 19 as shown in FIG. The inner surface 65a of the bent portion 65 against which the bar-shaped article 1 sliding down in the second chute 18 collides is about 2
An angle α of 5 ° (α may be an angle of 45 ° or less.)
It is formed so as to be inclined. This second shoot 1
According to 8, the bar-shaped article 1 that has slid down in a state where the inside of the first chute 17 is aligned (a state where the bar-shaped article 1 is parallel to the sliding direction) slides down in the second chute 18 in the aligned state. As shown in FIG. 12, the distal end of each bar-shaped article 1 collides with the inner surface 65a of the bent portion 65 in the sliding direction. Since the angle α between the inner surface 65a of the bent portion 65 and the sliding direction 66 is a relatively small angle of 25 °,
The rod-shaped article 1 has its inner surface 65a without disturbing its alignment.
, And slides down to enter the lower reservoir hopper 19. In this manner, the bar-shaped articles 1 can be supplied to the storage hopper 19 so as to stand upright next to each other.

Next, the reservoir hopper 19 will be described with reference to FIG. The reservoir hopper 19 includes a short cylindrical first main body 67 that receives the rod-shaped article 1 from the upper opening, a first gate 20 for opening and closing the lower opening of the first main body 67, A partition member 68 provided in the lower opening of the first main body 67. Partition member 6
Reference numeral 8 denotes a single rectangular plate-like body as shown in FIG. The partition member 68 is provided in a vertically upright position at a position passing through the center of the first main body 67.

The first gate 20 is the first left gate 20
a and a first right gate 20b. The first left and right gates 20a, 20b are supported rotatably about fulcrum shafts 69, 69 provided in the horizontal direction, and are rod-shaped in the reservoir hopper 19 in the closed position shown in FIG. The bar-shaped article 1 in the reservoir hopper 19 can be discharged at the open position indicated by the two-dot chain line while holding the article 1. Fulcrum shaft 6
9 and 69 are provided on the first main body 67. Note that, like the second gate 22, the first gate 20 is connected to each other by a link (not shown), and is opened and closed by a gate driving unit (not shown).
Since the link and the gate drive unit are the same as those of the filling hopper 21, detailed description will be omitted. When the first left and right gates 20a and 20b are closed, the upper surfaces of the first left and right gates 20a and 20b are 4
An angle β of 5 ° or less (in this embodiment, the angle β is set to about 20
°. ). Thus, the bar-shaped article 1 stored in the reservoir hopper 19
Can be raised at an angle of about 20 ° with respect to the vertical direction while being held along the first left and right gates 20a, 20b.

The partition member 68 is erected at an angle of 45 ° or less with respect to the vertical direction in a state where the bar-shaped article 1 is supplied into the storage hopper 19 and the lower end thereof is in contact with the upper surface of the first gate 20. It is provided so as to be held in a state of being held. That is, the partition member 34 provided in the filling hopper 21
Similarly, for example, even when the length of the bar-shaped article 1 is shorter than the interval between the inner surfaces of the first main body portion 67 of the storage hopper 19 facing each other, the bar-shaped article 1 is prevented from falling sideways in the storage hopper 19. Can be

According to the reservoir hopper 19, the second
The rod-shaped article 1 discharged from the chute 18 is temporarily stored in the storage hopper 19, and the rod-shaped article 1 in the storage hopper 19 can be supplied to the filling hopper 21 at a predetermined timing. Hopper 2 for filling article 1
1 can be relatively short.

Further, according to the filling device 14, as shown in FIG. 6, the bar-shaped articles 1 can be sequentially supplied to the filling hopper 21 of the filling mechanism 23 which is sequentially moving to a predetermined supply position. When the filling mechanism 23 moves to a predetermined discharge position, the bar-shaped articles 1 in the filling hopper 21 of the filling mechanism 23 can be sequentially discharged. Accordingly, the filling hopper 21 can be vibrated using the time required for each filling mechanism 23 to move from the supply position to the discharge position, and the bar-shaped articles 1 in the filling hopper 21 can be aligned. The filling capacity can be improved by an amount corresponding to the number of the sections 23.

However, in the above embodiment, the filling hopper 2
As shown in the plan view of FIG. 8 (a), the partition member 34 provided in the first hopper 1 is provided in a vertical state so as to form a cross. As shown in the plan view of FIG. 8B according to the inner diameter of the second main body 33 and the length of the bar-shaped article 1, the second main body 33 is vertically extended radially in three directions from the center of the second main body 33. You may provide in the state which stood in the direction. In addition, these three partition members 7
0 indicates that the heights are different.

Then, the first chute 1 of the above embodiment
In FIG. 7, the guide member 64 is provided in parallel with the sliding direction as shown in FIG. 10, but instead, a step portion 71 may be provided as shown in FIG. FIG.
The first chute 74 shown in FIG. 1 has a sliding surface on which the rod-shaped article 1 slides down, the height of which in the direction perpendicular to the sliding surface is lower than the inlet-side sliding surface 72 of the first chute 74 on the outlet side. A step portion 71 having a lower surface 73 is formed. According to the first chute 74, when the bar-shaped article 1 that slides down the entrance-side sliding surface 72 passes through the stepped portion 71, the rod-shaped article 1 is separated from the exit-side sliding surface 73 and falls, so that the exit-side sliding surface is reduced. 73 can be made to collide, and the impact of this collision can loosen the entanglement of the rod-shaped articles 1 entangled with each other. Then, the rod-shaped article 1 can be supplied to the storage hopper 19 in a state where the entanglement is loosened. In the above embodiment, the second gate 22 of the filling hopper 21 is opened and closed twice to open the bar-shaped article 1.
Alternatively, the bar-shaped article 1 may be discharged by opening and closing the second gate 22 once. Further, in the above embodiment, the bar-shaped articles 1 weighed by the combination weigher 13 are supplied to the filling hopper 21, but the bar-shaped articles 1 weighed by a weighing device other than the combination weigher may be supplied to the filling hopper 21.

[0061]

According to the filling apparatus and the filling method of the present invention, the rod-shaped articles supplied into the filling hopper can be erected adjacent to each other, so that the rod-shaped articles are aligned in this manner. Can be discharged. Thereby, for example, when filling a predetermined container with a predetermined weight or the number of rod-shaped articles, it is possible to fill the container in a state of standing upright so that it looks good next to each other without overflowing from the container.

According to the filling device of the first invention, for example, when the length of the bar-shaped article supplied into the filling hopper is shorter than the interval between the mutually facing inner surfaces of the main body of the filling hopper, the partition member is provided. If not, the bar-shaped article is placed sideways by the provision of the partition member so that the center axis of the bar-shaped article is 45 degrees with respect to the vertical direction.
It can be raised and held within a range of an angle of less than or equal to °. As described above, by providing the partition member having a shape corresponding to the length of the rod-shaped article, even a rod-shaped article having a relatively short length can be erected so as to be adjacent to each other without overflowing from a predetermined container. Can be filled in a state.

According to the filling device of the second aspect of the present invention, when all the upper edges of the partition member are formed at the same height, the bar-shaped articles supplied to the filling hopper are placed on top of the partition member. Although it may not be possible to discharge because it is on the edge, the vertical height of the predetermined portion of the upper edge of the partition member and the other portion are different, so that the The rod-shaped article abutting on the edge can be reliably dropped from the upper edge. Thereby, the bar-shaped article stored in the filling hopper can be reliably discharged.

According to the filling device of the third aspect, the bar-shaped article leaning on the partition member can be prevented from climbing over the partition member and falling. And, for example, FIG.
As shown in FIG. 5, when the two bar-shaped articles 1a and 1b are vertically overlapped in an upright state, the upper bar-shaped article 1a is gated so that the upper bar-shaped article 1a does not lean against the partition member. It can be easily dropped on the top.
Therefore, for example, when filling a predetermined weight or number of rod-shaped articles into a predetermined container, the rod-like articles can be reliably filled upright next to each other without overflowing from the container.

According to the filling device of the fourth aspect, since the vibration component of the vibration by the driving unit of the filling hopper is composed of the vertical component and the horizontal component, the rod-shaped articles in the filling hopper are entangled with each other. Can be erected on the gate in parallel with each other in a state of being adjacent to each other, and thus the rod-shaped articles can be filled in a container or the like in an aligned state.

According to the filling device of the fifth aspect, the position of the pivot portion and the position of the center of gravity of the filling hopper are located at a predetermined interval in the horizontal direction, so that the filling hopper is vibrated in the vertical direction. Only by doing so, the filling hopper can be swung over a horizontal range. Therefore, the filling hopper can be vibrated in both the vertical direction and the horizontal direction by a simple and compact mechanism for vibrating the filling hopper in the vertical direction.

According to the filling device of the sixth aspect, the filling hopper is caused to collide with the bar-shaped article by moving the filling hopper in the horizontal direction in a state where the bar-shaped article in the filling hopper is lifted from the filling hopper. The upper bar-shaped articles overlapping in the vertical direction can be dropped on the gate. As a result, the rod-shaped articles in the filling hopper can be aligned as described above, and the aligned state can be filled in a container or the like.

According to the filling device of the seventh aspect, the impact when the bar-shaped article is supplied to the filling hopper and collides with the gate by free fall can be reduced, so that the bar-shaped article jumps up due to the collision with the gate. Can be prevented, so that they are not entangled with each other in the filling hopper.

According to the filling method of the eighth aspect, all the bar-shaped articles supplied to the filling hopper can be reliably discharged. That is, even if the filling hopper in which a large number of bar-shaped articles are stored is vibrated, these bar-shaped articles are difficult to move in the filling hopper, and the bar-shaped articles caught in the filling hopper may not be shaken off. Most of the rod-shaped articles in the filling hopper are discharged in the first discharging step, and the filling hopper is vibrated again in a state where a large space is formed (second vibration step), so that the rod-shaped articles remain in the filling hopper. The rod-shaped article that has been shaken off can be reliably discharged (second discharge stage).

According to the filling device of the ninth aspect, the guide member can align the rod-shaped articles sliding down the chute in a direction parallel to the sliding direction. It can be supplied to the filling hopper in the state of being filled. Thereby, alignment of the bar-shaped articles in the filling hopper can be performed very easily in a short time.

According to the filling device of the tenth aspect of the present invention, when the bar-shaped article that slides on the slide-down surface on the entrance side of the chute passes through the step, the rod-shaped article falls away from the slide-down surface on the exit side and falls. The impact can be caused to collide with the side slide surface, and the impact of the impact can loosen the entanglement of the rod-shaped articles entangled with each other. Then, the rod-shaped article can be supplied to the filling hopper in a state where the entanglement is loosened.

According to the filling device of the eleventh aspect, the rod-shaped articles discharged from the chute are temporarily stored in the storage hopper, and the rod-shaped articles in the storage hopper are supplied to the filling hopper at a desired timing. Therefore, the bar-shaped article can be supplied to the filling hopper in a relatively short time. As described above, the supply time for supplying the bar-shaped articles to the filling hopper can be shortened, so that the time for filling the rod-shaped articles into the container or the like by using the filling device can be reduced.

According to the filling device of the twelfth aspect, the bar-shaped articles can be sequentially supplied to the filling hopper of the filling mechanism which is sequentially moving to the predetermined supply position, and the filling mechanism is provided with the predetermined discharge. When moved to the position, the bar-shaped articles in the filling hopper of the filling mechanism can be sequentially discharged. Therefore, the filling hopper can be vibrated using the time required for the filling mechanism to move from the supply position to the discharge position to align the rod-shaped articles in the filling hopper, thereby increasing the number of filling mechanisms. Thereby, the filling capacity can be improved.
