Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a powder medicine dividing device for dividing a powder medicine into predetermined doses such as one dose.

[0002]

2. Description of the Related Art Conventionally, such a powder dividing device has been used.
It is provided with a powdered medicine feeder composed of a hopper and a chute, and a distribution dish on which powdered medicine is dropped from the powdered medicine feeder. To divide powder into doses according to the prescription with this powder splitting device, first weigh the powder according to the prescription with a scale, store the measured powder in the hopper of the powder feeder, and tilt the powder feeder. The powder is dropped from the chute of the powder powder feeder onto the rotating distribution pan by vibrating.

Then, the dropped powder is evenly spread on a round groove having an arcuate cross section formed on the outer periphery of the distribution tray or a division mass arranged in a predetermined number in series, and the distribution tray on which the powder is distributed corresponds to a set division number. While being sent at a pitch, the powder in the R compound is scraped out in predetermined amounts, or the powder in each divided mass is sequentially taken out to divide the powder in predetermined amounts.

[0004]

By the way, in order to improve the accuracy of dividing powder in such a powder dividing device, it is necessary to uniformly distribute the powder from the powder feeder onto the distribution tray.

However, when the vibration amount, that is, the amplitude or the frequency of the powdered medicine feeder is set to be high from the beginning, the powdered medicine forms a lump at the time of the first dropping, especially when the amount of the powdered medicine accommodated in the powdered medicine feeder is large. It is often discharged, and the powder cannot be evenly distributed on the distribution dish, and if it is set low from the beginning, it can be evenly distributed on the distribution dish, but it takes time to deposit all the powder from the powder feeder. was there. This also applies to the tilt angle of the powder feeder, that is, the tilt angle of the chute with respect to the horizontal plane and the tilt angle of the hopper with respect to the chute (open angle).

Further, when the powdered medicine in the powdered medicine feeder becomes small due to the accumulation, the weight of the powdered medicine feeder containing the powdered medicine becomes considerably light. Therefore, if the powdered medicine feeder is vibrated with the same amplitude, the powdered medicine is dropped. Unevenness occurs,
There is also a problem that the powdered medicine cannot be evenly distributed on the distribution dish.

Therefore, according to the present invention, the amount of vibration and the tilt angle of the powdered medicine feeder are appropriately controlled so that the powdered medicine is efficiently and evenly dropped from the powdered medicine feeder to uniformly and quickly disperse the powdered medicine on the distribution tray. It is an object to improve the accuracy of and to shorten the time required for powdered drug accumulation.

[0008]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a powder medicine feeder based on the amount of the powder medicine contained in the powder medicine feeder, for example, the measurement data of the powder medicine actually measured by a measuring instrument. The initial vibration amount and the initial tilt angle were set, and the vibration amount and tilt angle of the powder medicine feeder during powder powder accumulation were increased over time. Further, the vibration amount of the powder medicine feeder may be increased until a predetermined time elapses, and then decreased, or the vibration amount of the powder medicine feeder or the initial setting value of the inclination angle or the amount of change over time depending on the type of powder medicine. You may make it correct.

In the powder medicine dividing device according to the present invention,
Since the initial amount of vibration and the initial tilt angle of the powdered medicine feeder are set to optimum values based on the amount of powdered medicine to be dropped, even if the amount of powdered medicine contained in the powdered medicine feeder is large, the powdered medicine will not be discharged at the first drop. The powder does not form a lump and is not discharged from the powder medicine feeder, and the vibration amount and the tilt angle of the powder medicine feeder increase with time, so that the time for spreading the powder medicine from the powder medicine feeder is also shortened.

Further, if the vibration amount of the powdered medicine feeder is reduced after a predetermined time has passed, even if the powdered medicine in the powdered medicine feeder becomes small, the vibration of the powdered medicine feeder is suppressed so that the powdered medicine does not become uneven. , If the initial value of the vibration amount or tilt angle of the powder medicine feeder or the amount of change over time is corrected according to the type of powder material, the vibration quantity or tilt angle is set to a large value for the powder material in which particles are difficult to flow finely, Since the amount of vibration and the angle of inclination of the powdered medicine, in which the particles are large and easy to flow, are set to be small, the powdered medicine can be evenly spread on the distribution dish.

As shown in FIGS. 2 and 3, the printing unit 15 and the heat sealer 16 include local sequencers 19, 20, and 2.
1 is centrally controlled by the control unit 22.

As shown in FIGS. 3 and 4, the powdered medicine feeder 9 is a hopper 23 in which a prepared powdered medicine is loaded and stored.
And a chute 24 which receives the powdered medicine discharged from the hopper 23 and drops it on the V-shaped measure 10.
The arm 25 supporting 4 is rotated by the pulse motor 27 via the link 26, and the inclination angle (opening angle) α of the hopper 23 with respect to the chute 24 is adjusted.

The powder feeder 9 is supported by a plate-shaped piezoelectric element 28 which is fixed in a tilted state. When a suitable voltage is applied to the piezoelectric element 28, the powder feeder 9 vibrates to shoot the powder in the hopper 23. It is dropped from and is deposited on the V-cell 10. Further, whether or not the powdered medicine is actually dropped is determined by the powdered medicine sensor 2 installed in front of the chute 24.
It is judged by 9. The determination by the powder medicine sensor 29, the rotation amount of the pulse motor 27, and the piezoelectric element 28

In order to uniformly disperse the powdered medicine on the surface and suppress the division error, the vibration amplitude of the powdered medicine feeder 9, that is, the voltage applied to the piezoelectric element 28 and the inclination angle α with respect to the chute 24 in the hopper 23.
And are systematically controlled by the control unit 22 based on various data as follows.

FIG. 5 shows the relationship between the amount of powdered medicine accommodated in the powdered medicine feeder 9 and the initial applied voltage applied to the piezoelectric element 28 at the time of dropping the first powdered medicine according to the particle size of the powdered medicine. As shown in FIGS. 1 to 3, the stored amount is measured by the measuring device 8 of the dispensation inspection device 2 at the time of dispensation and then grasped by the measurement data transferred to the control unit 22, while being stored in the piezoelectric element 28. The initial applied voltage of is accurately set by the control unit 22 based on the measured data and the data of the particle diameter and the unit time flow rate obtained from the prescription data. Further, the particle size of the powder may be selected from granules, powder or fine powder by the operation panel 30 shown in FIG.

As shown in FIG. 5, the initial applied voltage increases linearly with an increase in the amount of powdered medicine contained, and is set higher when the particles of powdered medicine are finer. That is, when the powder is difficult to flow due to the large amount of particles and fine particles, the initial applied voltage is increased and the amplitude of the initial vibration is appropriately increased to efficiently and uniformly drop the powder in a range that does not discharge it in a lump form. There is.

FIG. 6 shows changes with time in the applied voltage to the piezoelectric element 28 after the initial applied voltage is set as described above.

The voltage applied to the piezoelectric element 28 is based on the expected supply completion time calculated from the storage amount of powdered medicine and the unit time flow rate obtained from the above-mentioned measurement data, prescription data, etc.
As shown in FIG. 6, the powdered medicine feeder 9 depending on the initial applied voltage.
In the period (primary flow rate adjustment period) from the start of vibration to 90% of the expected supply completion time, the flow rate increases linearly by 30%, and thereafter the period until the powder supply is completed (secondary flow rate adjustment period) Period) decreases linearly. The slope of this decrease is set to be 30% of the initial applied voltage when the applied voltage to the piezoelectric element 28 has passed 120% of the expected supply completion time.

As described above, since the amplitude of vibration of the powdered medicine feeder 9 increases linearly during the primary flow rate adjustment period, the powdered medicine supply time can be shortened while suppressing the mass discharge of the powdered medicine during the initial dropping. However, since the amplitude of vibration decreases during the secondary flow rate adjustment period, even if the amount of powdered medicine in the powdered medicine feeder 9 becomes small, the powdered medicine will not drop evenly, and the V-cell 10

Then, the powdered medicine feeder 9 increases the inclination angle α at a constant rate during the primary flow rate adjustment period to shorten the powdered medicine supply time, and increases the inclination angle α at a higher rate during the secondary flow rate supply period. By doing so, all the powdered medicine to be stored is discharged. Further, when the supply of the powdered medicine is completed, the powdered medicine feeder 9 enters a cleaning period in which a small amount of the powdered medicine remaining is shaken off.
