Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for fully automatically dividing into two parts and packaging powder medicines to be administered to patients in hospitals, clinics, etc.

Conventionally, as a result of examining patients at hospitals or clinics, it is necessary to package drugs according to the symptoms of each patient, or especially in the case of powders, the ingredients and number of grams are not constant. Patients often rely on manual operations, resulting in patients having to wait for a long time at the counter. In order to deal with this, some devices have been considered to divide the powder into equal amounts and package it.Powders have different powder quality, such as powder, fine grains, fine rice grains, and fruit grains. Since their specific gravity and particle size are different, there is a problem that they easily separate even if they are mixed, and they are packed in the same sachet while maintaining the average mixing ratio. This has become a difficult task.

The present invention was developed in the early 1990s, and involves packaging different types of powder into equal portions, and controlling the blending ratio to match the ratio of ingredients to be administered to the patient. The purpose of the present invention is to provide a fully automatic powder dividing and packaging device that enables the following.

The implementation of division and packaging of powder in L period construction is as follows.
2.Explain. First, each powder feeder 1.1...
- Pour the pre-measured amount of powder into the container. Different types of powders may be stored in each powder feeder for each patient, and different types of powders may be mixed in advance and then fed into the feeder. When the next 42 electromagnetic vibration electromagnet 2G+2 is energized, the electromagnetic attraction part 19 is first attracted by the action of the electromagnet, and the vibration &16 moves to the electromagnet side against the elasticity of the elastic supports 1B and 1B, and then the second C2 electromagnet When the energization is stopped, the attraction force is cut off, and the elastic support members 18, 18 vibrate due to the recovered elasticity of the support members 18 and 16.
or surface rapidly. This movement of vibration value 16〃Shima support rod 15
, 15 to the powder feeder 11, and the introduced powder exhibits a movement of mixing while being slightly accumulated in the powder feeder 1. As a result, when powders of different sizes are fed into the same powder feeder, complete mixing is achieved and uniform preparation is achieved.

Next, the drive device 6 of the distributor 114 is operated to cause the distributor 4 to reciprocate in the direction of arrow B, and the powder feeder 1
C2 Open the attached opening/closing shutter 5 to the device. As a result, the powder drops from the opening of the opening/closing shutter 5 and is evenly distributed in each gutter-like container in the distribution 64. In this case, the distributor 4 does not necessarily need to distribute the entire dispersion agent 6, and can be driven with a reciprocating section determined so as to distribute only the amount corresponding to the number of packages C:.

Note: There is a correlation between the opening/closing shutter 5 and the amount of reciprocation 1 of the distributor 4; standard data on how many times the distributor 4 must be reciprocated to divide the medicine evenly (dispersion) has been experimentally determined in advance. Based on this data, perform the powder division as described in -ch.

In order to speed up the division, the aperture of the opening/closing shutter 5 is increased, the number of reciprocations of the distributor 4 is increased, the aperture of the distributor 5 is decreased, and the aperture of the distributor 4 is increased by 6. Set the number of round trips. All of these operations are either fully operated or automatically controlled by command signals issued from an electronic control device 9112 such as a computer, and the dispensing work proceeds.

When the distribution work for the distributor 4 is completed, the reciprocating movement of the distributor 4 is stopped, and the distributor 4 is moved as shown by the arrow C in the next diagram C31S.
rotates and drops the powder into divided squares of 7 circles. Incidentally, instead of the L lifting and turning machine 1111'', a powder transfer mechanism including an opening/closing mechanism such as the bottom of the distributor 4≦two bottoms may be provided.

Divided square 71kIII#x, each square 7m, 7b
... Inside≦=Powder is stored, and after traveling along the rail and reaching the introduction hopper 11 connected to the packaging machine $10, the shutters 7'a and 7'b are sequentially opened and the powder is transferred to the hopper. 11
The powder is dropped into the packaging mechanism 10 which automatically operates ≦2 times, and the powder is divided and packaged. Naoki's shutter 7'a
, 7'b, the opening/closing mechanism, the automatic packaging mechanism, etc. are all well known, so detailed explanation thereof will be omitted. At this time, it is also possible to drop arbitrary tablets into the introduction hopper 11 from a separately provided tablet compartment 14 and package them at the same time.

In the configuration described above, the powder feeder is not limited to the shape of the embodiment, but the feeder itself is configured to be rotatable,
When dropping the powder, a method may be used in which the powder is tilted appropriately and distributed through a hopper into the distributor. Furthermore, in this embodiment, if a photoelectric residual amount sensor is installed in the powder feeder 1 to constantly monitor the remaining amount of powder, more fine-grained control can be achieved.

By applying the device according to the present invention, the following effects are achieved. That is, each powder feeder is equipped with a vibration mechanism 2, which applies rotational vibration to the powder feeder. Since the vibration &16 and elastic support 18 are provided, the mixing effect of powders is extremely high, and even if powders with different particle sizes and specific gravity are mixed with each other, they can be averaged and distributed. It has a great effect.Of course, there is no adhesion of powder to the inner wall of the feeder, etc., and it is possible to distribute the powder uniformly without the weight #4IN during distribution.There are multiple powder feeders, and the purpose of distributing the powder is Depending on the situation, different powders can be stored separately and the dispenser 4 can be moved back and forth to each feeder repeatedly to dispense the desired powder, or mixed powders can be prepared in advance. It is also possible to use a usage method such as storing the dispenser in each feeder and dispensing the number of tickets for each patient at the same time (for five people in the illustrated example). By setting the movement arbitrarily, it is possible to dispense as many as the required number of sachets.
Feeder number, opening/closing degree and timing of the opening/closing shutter, length and speed of the reciprocating movement of the distributor 4 and timing of transfer to the divided mass 7, movement of the divided mass 7 and charging into the introduction hopper, and operation of the packaging mechanism 10. By inputting all timing-related data, all powder medicines can be divided and packaged automatically, and the work from prescribing to patients to dividing and packaging can be completed in a short time, making it easier for patients. This solves the problem of having to wait for a long time. Since the device itself can be made compact, it can be downsized and cost reduced, and can be adopted in large hospitals, small clinics, clinics, etc., and has great effects.
