Description

DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a powder feeder used in a packaging apparatus for dispensing powdered medicines, packaging the powdered medicines one dose at a time, dispensing the powdered medicine with a scraping device, dividing the powdered medicine, and packing the powdered medicine. .

2. Description of the Related Art A conventional powder feeding feeder hopper has:
It is attached to the hopper opening amount adjusting mechanism so that the supply amount can be adjusted according to the type of the medicine. This mounting structure is mounted on a frame-shaped support, supported by fitting, fixed by screws, or the like. Also, the powder hopper of the powder feeder needs to drop the powder attached to the surface of the powder hopper every time the prescription is completed, and the powder attached to the powder hopper is dropped into the trough part of the feeder by a striking device using a solenoid or by applying vibration. Cleaning.

By the way, the input hopper as described above is removed and washed once a day after the work is completed, and the mounting support is performed by supporting by inserting or fixing by screws. If it is supported, installation and removal is troublesome. In addition, the configuration in which the input hopper is mounted on the frame-shaped support does not require removal of the input hopper because the loading hopper is only mounted by its own weight on the input hopper opening adjustment mechanism, although it is not troublesome to remove it. When works, the frame-shaped support also inclines, so that the loaded hopper moves and the opening amount of the loaded hopper cannot be adjusted accurately. In addition, there is a problem that noise is generated when the striking device or the vibration device operates. Furthermore, when the powdered powder is put into the input hopper, the powdered powder must be able to prevent the powdered powder from scattering into the air, and must be arranged so that the dust collecting device can be easily attached. The present invention has been made to solve the above problems.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention has a vibration generating section, a trough connected to the vibration generating section, a charging hopper provided above the trough, and a charging hopper opening amount. The adjusting device and the input hopper supported by the input hopper opening amount adjusting device were supported using a catch mechanism, which can be pulled out and inserted substantially vertically. In addition, a cleaner device is provided for dropping the powder attached to the charging hopper into the trough by vibration. Further, a charging hopper is provided above the trough, and a dust collecting device is provided above the charging hopper.

5a is formed. On the other hand, the lowermost point 5b of the R-shaped concave portion
The outer peripheral edge 5c of the R is set at a curvature angle of R of about 50 degrees.
The outer peripheral edge is larger than the warped height of the inner peripheral edge 5a.
5c warp height is set high and feeder 1
The powder to be dispensed moves the R dispensing dish 5 at the rotation speed of the above condition.
Even when rotated, the powder does not scatter due to the centrifugal force of the R distribution dish
In order to Outer side of lowermost point 5b of R-shaped recess
A support for rotating the R distribution dish is further provided on the outer peripheral portion of the edge 5c.
The flange 5d for holding the retaining ring 6 is formed integrally with the R distribution plate.
Have been. FIG. 6 shows an R distribution from the feeder trough of the present invention.
It is a figure showing falling to a plate. It should be noted that, in the configuration described above,
The description is omitted by using the same reference numerals. Trough 3
Of the trough 3 has two guide grooves 3a3b
Centering on the lowest point 5b of the R-shaped depression, on the position on both sides
Is located on the side. The powder dropped from the guiding groove 3a is
It hits the slope of the R distribution dish from the inner peripheral side edge 5a,
The powder splashes in the direction of the lowermost point 5b of the depression, and drops from the guiding groove 3b.
The dropped powder is applied to the slope of the R distribution dish from the outer peripheral edge 5c.
Powder powder jumps toward the lowermost point 5b of the R-shaped depression.
I do. In the trough 3 of FIG. 6, since the guide grooves 3a3b are shallow,
The feeder vibrates strongly and the supply of trough 3 increases when the supply increases.
The powder falls from the entire feeding port, but among them, the guiding groove 3a
Because there are many powders that fall from 3b, basically
Characteristics occur. FIG. 7 is a view showing a second embodiment of the present invention.
There are two trough 3 supply ports as shown in this figure.
Have been. There are two guide grooves 3a3b and two trough 3 supply ports.
Falls from the guide groove 3a when considered as the same configuration.
The powder hits the slope of the R distribution dish from the inner peripheral edge 5a,
The powder splashes in the direction of the lowermost point 5b of the R-shaped depression, and the guiding groove 3
The powder dropped from b is placed on the R distribution dish from the outer peripheral side edge 5c.
On the slope, towards the bottom point 5b of the R-shaped depression
The powder splashes. At this time, as shown in FIG.
Of the trough 3
The powder that falls from the container falls only from the guiding grooves 3a3b.
Therefore, the characteristics as described above occur. This is illustrated in FIG.
As shown in FIG. 19, a conventional traverse having only one guiding groove
In R, the drop point of the powder falling from the guiding groove is distributed to R
It is arranged at the position of the lowest point 5b of the concave portion of the R shape of the dish,
For this reason, the falling powder is sandwiched between the lowermost points 5b of the R-shaped depressions.
The powder that has fallen from the inner peripheral side edge 5a
In the direction of the bottom of the R-shaped depression 5b
The amount of powder dropped from the side edge 5c is large in the outer peripheral side edge 5c direction.
Bounce. Also, the height of the bouncing at this time is the inner peripheral side edge 5a or
Those that jump beyond the height of the outer peripheral edge 5c are deposited on the R distribution dish.
It accumulates inside the dispenser without stacking, and the bouncing height is on the inner circumferential side
Those that do not exceed the height of the edge 5a or the outer peripheral edge 5c are R-divided.
The lowest point of the R-shaped dent on the wall of the dish
It rebounds in the 5b direction. 18 and FIG. 19 were compared.
In this case, although it depends on the feeder supply,
Due to the rebound of powdered medicines (the lowest point of the R-shaped depression)
Induction to fall with a certain width across 5b
The powder falling from both sides of the groove is in the characteristic direction shown in Figs. 6 and 7.
(Bounce) is preferable because the bounce is canceled. like this
The drop characteristics appear humble in granular form powders,
It is highly effective for powders that are easily scattered from the R distribution dish by centrifugal force.

Each of the powders that have dropped falls on the lowermost point 5b of the R-shaped depression.
Bounces in the direction, and the bounced powders hit each other.
It deposits at the position of the lower point 5b. For this reason, the powder is R distribution dish
There is little scattering from 5 and the trough has a tip of 2
Because it is down to the stage, the fall height is suppressed and it is difficult to jump
The cross-sectional shape deposited on the R distribution dish 5 is an R-shaped concave portion.
The powder at the top of the line at the lowest point 5b is high and it is difficult for powder to accumulate.
Disperse and deposit to the right. High speed R distribution dish as in the present invention

The range of the inner peripheral side edge 5c of the R distribution dish 5 is set as a speed adjustment section.
You have set. This speed adjustment section is
That the plate 14 has reached the inner peripheral edge 5c of the R distribution dish 5
The guide plate 13 is not
The point is whether it has reached, for example, the division of the R distribution dish 5
When the feed angle is small, the leading end of the guide plate 13 has an R distribution.
The split feed angle is set to the next position earlier than reaching the position of the plate 5c.
Reach the stopping point. For this reason, it is reduced in the rotation axis x speed adjustment section.
No need to speed up, but fewer packaging sets
And the split feed angle of the R distribution dish 5 is correspondingly large.
At a constant speed in the rotation axis x speed adjustment section.
Rotation, the split feed angle will reach the next stop point.
The tip of the guide plate 13 reaches the position of the R distribution plate 5c quickly.
Reached, and deposited when rotating the rotation axis x
The guide plate 13 is in contact with the powder,

As shown in FIG. 14, the rotation drive of the R distribution dish 5 is provided at the center.
Can not be supported, the support ring 6
And the support ring 6 is rotatably supported by the bearing 17.
I have. The support of the R distribution dish 5 is heavy in such a device.
It plays an important role, and there is a problem with the means of rotation support
And the vibration generated during rotation of the R distribution dish,
The powder is concentric with the lowest point 5b of the R-shaped concave part
Distributed in rows or eccentrically, or on a part of the circumference
A phenomenon in which powder concentrates occurs, directly affecting the division accuracy
I do. A technology that solves this technology related to rotation support
And easily solved by supporting it on the center axis of rotation of the R distribution dish
However, as in the present invention, the center of rotation of the R distribution dish
When scraping out the powder in the axial direction, at least
Restriction for supporting the rotation of the R distribution plate outside the inner peripheral edge 5a
Outside the inner peripheral edge 5a of the R distribution dish.
In order to support the rotation of the R distribution dish with the bottom of the R-shaped recess
From the relationship between point 5b and the rotation support means, the rotation axis of the R distribution dish is the same.
It is difficult to adjust the mind when assembling, and
If the ring 6 is separated from the rotation axis of the R distribution dish in the outer circumferential direction,
The more the concentricity of the rotation axis of the R distribution dish is
There is a relationship that the difficulty of adjustment increases. Conventionally, R
When rotating the distribution dish at 30 rotations per minute, the R
Move the rotating support of the dish to some extent in the outer circumferential direction from the rotating shaft.
It is also possible to support it upside down, but 60 rotations per minute
In the case of the present invention rotated by R, press the R distribution dish
Accuracy and shape must be strictly required.
Support the position with high peripheral speed with the bearing 17 etc.
There are other conditions such as
If the powder is not devised, the powder that scatters
Noise between the ring 17 and noise that could not be considered in the past
Conditions that cause (Conventionally, R distribution dish
The support has a low rotation speed inside the drop position of the powder dispensing dish.
It ’s fast and you do n’t have to worry too much about bearing placement
The problem that scattered powder gets stuck between the support ring and the bearing
No problem occurs. From these facts, between the support ring 6 and the bearing 17
The problem is that the R distribution dish 5 vibrates,
The powder inside is the concentric circle of the lowest point 5b of the R-shaped depression.
Meandering or eccentrically distributed or part of the circumference
There is a problem that the powder concentrates on the minute
Therefore, in the present invention, as shown in FIG.
The contact portion with the ring 17 is located at the position of the flange 5d of the R distribution plate 5.
Below the inner peripheral side edge substantially inward of the outer peripheral diameter of the flange 5d.
By setting the outer diameter to a position outside 5a, the powdered medicine being dispensed will fly.

Never bite into The bearing of the support ring 6
17 is lower than the position of the flange 5d of the R distribution plate 5
In the case where the outer diameter of the flange 5d is set to a position substantially in the outer radial direction,
Under the conditions such as centrifugal force from the R distribution dish 5,
When provided inside the parabolic range, the support ring 6
Powder may bite into the contact area between the bearing and the bearing 17
Is not a serious problem.

As described above, according to the present invention, a plurality of fall point guideways provided on the trough are provided, and each of the fall point guideways provided on the trough is sandwiched between the lowermost diameter positions of the annular R-shaped concave portions. When the powder is supplied to the R-shaped depression by rotating the dispensing dish by arranging the drop point guideways on the side and the outer side, the lowermost diameter position of the annular R-shaped depression The powder feeder is arranged so that the powder falling on the inclined part on the inner diameter side and outer diameter side is repelled to the position of the lowermost diameter of the annular R-shaped recessed part, so that the depth of the R groove of the distribution dish can be reduced. If the powder dispensing tray is rotated at high speed or the powder dispenser is rotated at a high speed, the height of the powder dropping from the powder feeder is limited or the powder dropped from the feeder caused by the high speed rotation jumps out of the dispensing tray. Can be solved. Further, by forming the trough as a trough having at least two levels of horizontal surfaces in the process of transporting the trough, and making the powder fall port close to the annular R-shaped recess, the effect is more enhanced. In addition, by providing a charging hopper above the trough and providing a dust collecting device above the charging hopper, it is possible to prevent the powdered medicine of fine particles from scattering into the air.

As described above, according to the present invention, the loading hopper can be easily attached and detached, and even if the hopper opening adjusting mechanism is operated, the hopper opening can be adjusted reliably, and the striking device and the vibration device can be operated. No longer generated noise. Further, since the dust collecting device is provided in the upper part of the charging hopper, it is possible to prevent the powder of fine particles from scattering into the air when the powder is charged into the hopper.
