Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a powder medicine automatic packaging machine.

[0002]

2. Description of the Related Art Conventionally, the work of dividing and packing powdered medicine has been performed as follows. That is, several kinds of required powders are weighed out according to a prescription from various kinds of medicine bottles stored and mounted on the powdered medicine dispensation stand, and further, these are put into a mortar or an agitator and mixed. Then, this admixture is divided and packed by a dividing and packing machine. Such a dividing and packing machine is roughly classified into a hopper system and a V-mass system. In the hopper system, a rotary disk having a predetermined number of drug distribution holes in its peripheral portion is arranged below a hopper into which an admixture is to be charged. In addition, a packaging device is arranged below it, and the hopper charged with the admixture is vibrated by a vibrator to release the admixture downward, and at the same time, the rotating disc is rotated to release the above-mentioned release. The admixture is configured to be evenly distributed in the drug distribution holes of the rotating disk, and further, the bottom plate of the distribution holes can be opened and closed, and the admixtures in the distributed distribution holes can be individually loaded into the packaging device. The product is discharged and dropped, and a predetermined number of packages are packaged by a packaging device. Also, V
The box method has a cross section of approximately V due to the inclined inner and outer walls.
The letter-shaped mass is formed in a ring shape, and the inner wall is configured to be movable up and down so that a drug release gap is formed between the lower end of the outer wall and the lower end of the inner wall as the inner wall rises. A rotary disk having a drug distribution hole is arranged below, and a packaging device is further arranged below it. Then, the admixture is poured into the V mass and the upper surface is leveled, and then the inner wall is raised in this state to drop the admixture into the medicine distribution holes of the rotating disk, and the bottom plate of the distribution holes. The packaging is opened by opening the packaging device. As described above, in the conventional powder medicine divided and divided work, the admixture is manually prepared, and then the medicine is divided and divided by the mechanical work.

[0003]

However, all of the conventional divided and packaged work of powdered medicines have the following problems. That is, it occurs due to the adhesiveness of the powder, and there are contamination, division error, mixing error, etc. Contamination causes the powder that was dispensed and divided and packaged in advance to remain, and then dispensed and divided and packaged. The problem is that the previous powder mixes into the powder.
The division error is a problem that the weight of the admixture preliminarily weighed and prepared does not match the sum of the weights of the admixtures packaged, and that the individual package weights are finally different. . The former is caused by the gradual deposition of powder in a place with a large amount of powder attached such as a hopper or a complicated distribution process in a machine.The latter is caused by mechanical error. The amount of division and further the amount of packaging are different. Further, the mixing error is a problem that the mixing ratio of various powders in each final packaging agent is not uniform. This is particularly likely to occur when a small amount of powder is mixed, and since the mixing is not uniform, there is a problem in that the powder is not mixed in a package. The above problems are serious and serious because it is not possible to expect uniform drug efficacy. In addition to the above, there is a problem of chemical dust. This is because the chemicals are scattered in the air when the dispensing work is performed manually, and the dust collector has been used to manage the health of the dispensing room and improve the environmental hygiene, but it is not sufficiently effective. Further, since it is necessary to introduce large-scale equipment such as a dispensation table and a divisional packing machine, there is a problem that the dispensation room must be wide. In addition, it takes at least 20 to 30 minutes from dispensing to divided sachets, and since each pharmacist must perform the work individually, a great labor cost is required and waiting time for the patient is required. And the number of remaining medicines increases, which is a problem. In addition, there is a problem that inventory management of chemicals is troublesome.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems of the prior art, and to provide an automatic powder dispensing machine capable of handling various kinds of powders and automatically carrying out the packaging work thereof. To do.
