Description

[Detailed Description of the Invention] The present invention relates to a powder dividing and dispensing device that is conveniently attached to various drug packaging machines.

Traditionally, in hospitals, clinics, etc., powders have been divided into halves or used in combination with automatic packaging machines to seal powders alone or together with tablets in the same packaging bag, but unlike tablets, powders have a simple Since it is difficult to divide by weight, a powder divider using a ring-shaped dividing mass and a known powder feeding device (powder feeder) has been put into practical use in order to automatically perform weight division using a balance etc. It is provided.

The above-mentioned powder feeding device is usually connected to a powder distributor, a flow rate control unit, a feeder, an electromagnetic vibrating unit, etc., and uniformly distributes powder having a predetermined weight in a ring-shaped divided mass that is constantly rotated. It causes division.

The above-mentioned powder feeding device is an effective means for dividing powder, but it requires an electromagnetic vibration device and a feeding machine driven by it, and has the drawbacks of being expensive and having a complicated mechanism. there were.

The present invention is a powder dividing and distributing device devised in view of the above, and aims to further improve the conventional device to obtain a device that is relatively simple from a mechanical point of view and has good dispensing efficiency. In order to achieve the above purpose, it has a rotating hopper with a drop hole in the center, and a conical protrusion that protrudes from below the drop hole and maintains a slight gap with the lower end of the drop hole. , and a powder dividing and distributing device characterized by comprising a distributor configured to be freely rotatable in the opposite direction to a rotating hopper, and a plurality of dividing cells provided integrally with or adjacent to the distributor. That is.

An embodiment of the present invention will be described below with reference to the drawings.

Further, bottom covers 14, 14 are attached to the bottom of each divided square 9, 9 so as to be openable and closable by means of pivots 15, 15, and an operating piece 16
, 16 are moved in the direction of arrow C by a swinging rod 17 to open and close them.

Reference numeral 18 indicates a packaging mechanism, which includes an introduction hopper 19 that is commonly installed in each divided square, and an input port 19 to the packaging mechanism that seals and packages the powder that is loaded in bulk by the hopper.
' is provided.

Reference numeral 20 denotes a winding frame, in which the packaging strip 21 folded in half is pulled and driven by a shift mechanism 22 and moved to the input port 19'.
This conceptually explains the mode in which the powder is introduced and moved sequentially and intermittently.

Reference numeral 23 indicates a marking and vertical direction dividing line welding mechanism, and 24 indicates an enclosing line welding mechanism, and a known packaging mechanism may be used for both.

The bottom cover 14 mentioned above is attached to the bottom surface of all the divided cells, and the divided cells are rotated and opened to the input port 19 to the packaging mechanism.
When the container reaches the top of the container, the bottom lid opening/closing mechanism is opened/closed to perform separate packaging.

The present invention relates to a powder dividing and dispensing device having the above-mentioned mechanism as its basic structure, and its basic operation is as follows.

The powder to be divided into equal parts is weighed and placed all at once into the rotating hopper 1.

On the other hand, the dividing squares in the distributor are divided into 42 squares, 21 squares, 14 squares, etc. in advance according to the number of packages to be divided into the desired number of packages.

At the center of the rotating hopper 1, there is a gap a between the conical protrusions 7 that protrude from below with respect to the drop hole.
can be arbitrarily adjusted, and the gap is kept in a closed state during the metering, and after the dispensing operation is started, it is adjusted to maintain an appropriate gap depending on the type of powder and the amount to be dispensed.

For example, 0.5 kaku, 1rIr! IL, 5rIr! It is also possible to open n1 to about 1- or more, thereby making the distribution speed variable.

Moreover, since the rotating hopper 1 and the conical protrusion 7 are driven to rotate in opposite directions, accumulation and uneven distribution of the powder can be prevented, and a smooth distribution mechanism can be obtained.

After dispensing the powder corresponding to the desired number of packages through the above operations, the bottom lid opening/closing mechanism and the packaging mechanism are driven to perform the dispensing.

The drive of the bottom lid opening/closing mechanism and the packaging mechanism described above are as follows:
It is also possible to synchronize the operations based on commands from a control device (not shown), and at the same time print out the prescription number, drug type name, and other necessary data using the marking mechanism.

FIG. 3 shows an example of an application of the present invention.

Immediately, among the powder dividing and dispensing devices according to the present invention, devices with different numbers of packages are housed in the same case 25, and when distributing powders, a distributor is selected and used according to the purpose. It is something.

In the illustrated example, for example, 26 is a 14-mass distributor, 27 is a 2-mass distributor, and 27 is a 2-mass distributor.
The 1-mass distributor 28 is distributed as a 42-mass distributor, and after completing the division of the powder using the distributor corresponding to the desired number of packages, the powder is moved along the rail 29,
The packaging operation is carried out at the loading section 30 to the packaging mechanism, which is located approximately in the middle.

Note that 31 indicates a dust collection filter provided inside the case 25.

The configuration, operation, and application examples of the powder dividing and dispensing device according to the present invention have been explained in detail above based on examples, and by adopting this device, various effects described below are exhibited. .

That is, the rotating hopper and the conical protrusion are configured to rotate in opposite directions by the operation of the drive member while maintaining a gap between the lower end of the rotating hopper and the circumferential surface of the conical protrusion, so that the rotating hopper and the conical protrusion are evenly divided. If the powder to be used is simply put into the rotating hopper all at once, the powder will be distributed evenly and automatically in the circumferential direction without being accumulated or unevenly distributed between the rotating hopper and the conical protrusion. Therefore, the powder can be evenly divided into a plurality of dividing squares arranged annularly around the conical protrusion.

In addition, it eliminates the need for complicated operations such as traditional hand-side weighing, and is mechanically simpler than powder feeders that use electromagnetic vibration, allowing accurate powder division. That is.

By rotating the rotary hopper 1 and the distributor 10 in opposite directions, the falling speed of the powder becomes uniform over the entire surface, and division into the desired number of packages can be carried out in an extremely short time.
In the next stage, by quickly feeding it into the packaging mechanism,
Sachets can be obtained quickly.

The falling speed of the powder into the divided masses can be finely adjusted depending on the type of medicine, etc., and when making the fine adjustment, the height of the rotating hopper 1 is adjusted by loosening the handling device 5, and then it is tightened and fixed. It is extremely easy to operate.

Furthermore, as shown in Figure 3, by setting up multiple different types of powder dividing and dispensing devices in advance and using the device according to the purpose, it is possible to immediately respond to any number of packages. This allows for faster work.

This device may be used alone, but by incorporating it into a tablet packaging machine that utilizes a dividing mass, a tablet powder packaging machine can also be realized.

In the above case, it is possible to package tablets and powders together in the same package, or to package either one alone or in combination with special tablet side packaging, which can be used in a wide range of applications. Therefore, it is effective for use in packaging machines in hospitals, clinics, etc.
