BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a powdered medicine fixed quantity take-out apparatus for taking out a fixed quantity of powdered medicine.

[0002]

2. Description of the Related Art In recent years, in order to rationalize dispensing operations in pharmacies such as hospitals, tablets stored in a tablet feeder are automatically discharged by a specified number of tablets, and the tablets are packaged one by one. A tablet packaging machine has been realized.

The main reason why such an automatic tablet packing machine is realized is that a tablet feeder capable of discharging the instructed number of tablets only by instructing the number of tablets to be ejected has been put into practical use. It depends.

[0004]

However, as for powdered medicines, a powdered medicine feeder such as a tablet feeder capable of quantitatively discharging the indicated quantity by simply indicating the quantity to be discharged has not been put into practical use. Therefore, there is a problem that an automatic powder dispensing and packaging machine cannot be realized.

It is an object of the present invention to solve the problems of the above-mentioned conventional ones and to provide a powdered medicine fixed quantity take-out apparatus capable of containing the powdered medicine and taking it out in fixed quantity.

[0006]

In order to achieve the above-mentioned object, the present invention has a dividing hole capable of accommodating powdered medicine in a container having an outlet, and the dividing hole is formed by moving the dividing hole. A fixed-quantity dividing member that can communicate with the outlet and a partitioning member that separates the outlet from the remaining space in the container excluding the dividing hole are provided.

[0007]

According to the present invention, by adopting the above means, the powdered medicine in the container is accommodated in the dividing hole of the fixed amount dividing member and is taken out in a fixed amount from the outlet as the fixed amount dividing member rotates.

[0008]

1 and 2 show an embodiment of a powdered medicine quantitative dispensing device according to the present invention, wherein 1 is a cylindrical container having an open upper end, and a bottom plate 2 is provided at the bottom of the container 1. An outlet 4 having a circular cross section is formed at one position which is fixed and is displaced from the central hole 3 of the bottom plate 2. A rotary shaft 5 is rotatably inserted into a center hole 3 of the bottom plate 2 via a dry bearing 6, and a fixed-quantity dividing plate 7 having a diameter slightly larger than the inner diameter of the container 1 is located close to the upper surface of the bottom plate 2 on the rotary shaft 5. Fixed, fixed division plate 7
At the same time, the three division holes 8, 8 having a circular cross section, which can communicate with the outlet 4 due to the rotation thereof, are approximately 120
It is arranged with an angle distribution of °. A partition member 9 that separates the outlet 4 from the remaining space in the container 1 excluding one dividing hole 8 is fixed in proximity to the upper surface of the fixed quantity dividing plate 7, and the partition member 9 is Through hole 11 through which the rotary shaft 5 is rotatably inserted through the dry bear link 10.
In addition, a scraper 12 made of silicon rubber is attached to scrape the powdered medicine in the dividing hole 8 while contacting the upper surface of the fixed amount dividing plate 7 with the rotation of the fixed amount dividing plate 7.
At the tip of the rotary shaft 5 inserted through the through hole 11 of the partition member 9, a rotary arm 13 rotating with the rotary shaft 5 is provided.
Is fixed close to the upper surface of the partition member 9, the rotary arm 13 removes the powdered medicine accumulated on the partitioning member 9 within the angular area of the partitioning member 9, and removes the powdered medicine inside the container 1 outside the angular area of the partitioning member 9. It is designed to stir.

The dividing holes 8, 8, 8 have the same diameter and height as each other, and the powdered medicine can be accommodated as it is. For example, the outer diameter and the height are the same as the diameter and height of the dividing hole 8. Identical, with arbitrary inner diameter, and outlet 4
The amount of powdered medicine can be arbitrarily set by using a cylindrical piece (not shown) configured so as not to drop from the dividing hole 8 even when it comes directly above. That is, if each of the three dividing holes 8, 8 and 8 is loaded with a piece having the same internal volume corresponding to the packaging amount of one package, each dividing hole 8 has a predetermined amount corresponding to one package. Powder can be stored, and if three division holes 8, 8 and 8 are loaded with a piece having an internal volume corresponding to the total packaging amount of one, the three division holes 8 A predetermined amount of powder corresponding to one package can be accommodated in the holes 8, 8 and 8, and the three divided holes 8, 8 and 8 each have a different inner volume (for example, a standard inner volume). By loading a piece having an internal volume of 1 time, 2 times, or 3 times the capacity), it is possible to store a different fixed amount of powder in each divided hole 8.

Next, the operation of the powdered medicine fixed quantity dispensing device constructed as described above will be explained. First, each division hole 8,
8 and 8 are loaded with pieces (not shown) having a predetermined internal volume as needed, and an appropriate powder is stored in the container 1. Then, when the rotary shaft 5 is rotated by an appropriate driving member (not shown) such as a pulse motor, the powdered medicine is first stored in the piece of the dividing hole 8 outside the angular region of the partition member 9,
This penetrates into the angular region of the partition member 9 as the fixed quantity dividing plate 7 rotates, but at this time, the powdered medicine in the piece of the dividing hole 8 is scraped off by the action of the scraper 12 and becomes a storage amount equal to the inner volume of the piece. , Then the dividing hole 8 is the outlet 4
When it comes directly above, a predetermined amount of powdered medicine contained in the piece falls from the outlet 4 and is taken out.

That is, if each of the three dividing holes 8, 8 and 8 is loaded with a piece having the same internal volume corresponding to the packaging amount of 1 minute, the dividing hole 8 is divided into 1 package. A corresponding predetermined amount of powder is stored, so
Every three rotations, one package of powdered medicine is taken out from the take-out port 4.

Further, if a piece having an internal volume corresponding to the total packaging amount of the three divided holes 8, 8 and 8 is loaded, the three divided holes 8, 8, A predetermined amount of powdered medicine corresponding to one package is accommodated in accordance with 8, so that each time the fixed quantity dividing plate 7 makes one rotation, one package of powdered medicine is taken out from the take-out port 4.
It is taken out in batches.

Further, the three divided holes 8, 8 and 8 each have a fixed internal volume (for example, 1 of the reference volume) with different accommodating amounts.
(2 times, 2 times, 3 times the internal volume) pieces are loaded, each divided hole 8 contains a different fixed amount of powder,
Therefore, for example, if the division hole 8 loaded with a piece having an internal volume of one time the reference volume is repeatedly reciprocated between the outlet 4 and outside the angular region of the partition member 9, the outlet 4 is equal to the reference volume. A quantity of powder is repeatedly taken, which is 2 standard volumes
The same applies to a piece having a double or triple inner volume. In addition, the division hole 8 loaded with a piece having an internal volume twice the reference volume is reciprocated twice between the outlet 4 and the outside of the angular region of the partition member 9, or the internal volume is 1 time the reference volume. By reciprocating the dividing hole 8 loaded with the above-mentioned piece and the dividing hole 8 loaded with the piece having an internal volume three times the reference capacity once between the outlet 4 and the outside of the angular region of the partition member 9. A total of 4 times the standard amount of powdered medicine is taken out from the take-out port 4. Further, the division hole 8 loaded with a piece having an internal volume twice the reference capacity and the division hole 8 loaded with a piece having an internal volume three times the reference volume are provided outside the angular region of the outlet 4 and the partition member 9. If you reciprocate once between
In total, 5 times the reference volume of powdered medicine is taken out. In the same manner, any partition hole 8, 8 or 8 out of the partition holes 8, 8 or 8 in which the respective pieces having the inner volumes of 1, 2 and 3 times the reference capacity are loaded is separated from the outlet 4. By rotating the member 9 outside the angular region by a predetermined number of times in the reciprocating direction, a desired amount (a desired multiple of the reference volume) of powder is dropped and taken out from the outlet 4. .

In the above embodiment, the three dividing holes 8 are provided, but the number is not limited to this, and in the above embodiment, the outlet 4 is formed in the bottom plate 2 of the container 1, but this is not a limitation. In addition, in the above embodiment, the container 1 was formed into a cylindrical shape and the fixed quantity dividing plate 7 was rotated around the central axis of the container 1, but the present invention is not limited to this. Further, in the above-described embodiment, the dividing hole 8 for dividing the extracted predetermined amount of powdered medicine from the remaining powdered medicine in the container 1 is filled with the powdered medicine by its own weight. Alternatively, in the above embodiment, a predetermined amount of powder to be taken out is naturally dropped from the take-out port 4 provided in the bottom plate 2 of the container 1 by its own weight. For example, a nozzle is provided at the take-out tip. Alternatively, it may be extruded or ejected by air or other pressure. Furthermore, in the above embodiment, the fixed amount of powdered medicine was taken out from the container 1. However, for example, if it is configured such that a predetermined amount of the taken out powdered medicine is packaged by an appropriate powdered medicine packaging machine packaging device, an automatic powdered medicine dispensing machine is provided. It can be used as a powdered medicine feeder of the above, and at that time, not only the discharged powdered medicine is directly dropped into the packaging apparatus, but also an appropriate extrusion apparatus or conveying apparatus using air or other pressure is used. May be guided to the packaging device, other various inventions of the above embodiment,
It goes without saying that it can be modified.

[0015]

Since the present invention is constructed as described above,
If an appropriate powder is stored in the container, the powder can be stored in the dividing holes of the fixed amount dividing member and can be taken out in a fixed amount from the outlet as the fixed amount dividing member rotates. It can be practically configured as a powder medicine feeder capable of quantitatively discharging the specified quantity only by instructing the quantity to be supplied. It has excellent effects such as realization.
