The present invention relates to pharmaceutical equipment, specifically, to devices for grinding CT and removing them from the dust.

Known automatic line German company KILIAN, intended for the production of compressed tablets (see attached brochure). The line includes the installation to Saltovka and aspiration (dedusting) tablets containing a vertical cylindrical housing, which is installed inside the screw mechanism. Tablets coming from Tabletpress, captured by a screw, rise and purging. During tedding auger tablets with them are removed sharp edges and sucked the dust.

The disadvantages of the installation KILIAN should be attributed to its low productivity and high costs associated with construction of a screw mechanism, which occupies almost the entire volume of the body. For this reason, the processing of the other tablets (with a different diameter, fragility, and so on), you need to choose a new installation of the proposed firm KILIAN range.

More productive, in our opinion, is the technology of Saltovka and aspiration tablets with the use of an inclined drum with inner pouring node. Search by IPC class A 61 J 3/00 revealed no patents relating to devices for Saltovka and aspiration medicinal tablets. On the other hand, from the Ural branch of the nya known in the art installation for Saltovka, aspiration and sorting non-medical items, such as a device for sorting flat crystals containing a cylindrical casing with mechanical disks, one of which is connected with the actuator, and a pneumatic chamber (see A.S. USSR №997842, 07 4/08, 1983).

Closest to the proposed invention is the air-mechanical separator for fractions involving connected with aspiration system housing, which is equipped with a driving net drum with pouring shelves inside (see RF patent №2010622, CL VV/00, 1994 - prototype).

The disadvantages of the prototype should include the lack of modes Saltovka for different medicinal tablets.

The technical challenge is to extend the functionality by providing modes Saltovka and aspiration required for various medicinal tablets.

The technical result is achieved by the fact that in the plant for Saltovka and dust control pills, including the base of the rack, the drive is connected to the suction system of the body, inside of which is placed equipped with a pouring device net drum, kinematically associated with the drive pulley is located by means attached to the surface of the radial rods connected with bearing units mounted on the axis, the issue is Lannoy in the form attached to the housing of the perforated pipe, one end plugged and the other is equipped with a pipe for supplying compressed air into the drum, equipped pouring spiral in the form of a tape attached to its surface, in this case hinged on the racks are adjustable in height. The unit has a frequency Converter supply voltage, a funnel for filling tablets, the tray for the issuance of tablets and a branch pipe for connection to the suction system, and the mechanism of the rack contains the associated toothed coupling a pair of screws, one of which has a left hand thread.

Not obvious in the proposed solution is that medicinal tablets will galuut and dedust in mesh drum with inner pouring spiral, and the mode of Saltovka set by tilting the axis of the drum and the speed of its rotation.

The invention is illustrated by drawings on which is shown: figure 1 - General view of the installation figure 2 - cross section a-a of figure 1.

The apparatus comprises a base 1 with the racks 2, 3 are height adjustable with built-in screw mechanism 4. In the specific example mechanism 4 comprises a pair of screws with different thread and coupling. On racks 2,3 by means of the hinge 5 has a housing 6. Placed inside the mesh drum 7, movably mounted on the axle 8 by means of two bearing assemblies 9. The axle 8 is made in the form perform vannoy pipe. Left (drawing) end of the tube is plugged, and the left bearing housing 9 is connected to the shaft of the electric motor 10 by means of the coupling 11. The other end of the tube has a nozzle 12 for supplying compressed air. Inside the drum is fixed pouring spiral 13, made of a flat belt, the width of which is selected from the condition of maximum diameter of the tablets produced by this equipment. Case 6 provided with a socket 14 for connection to an aspiration system, a hopper 15 for loading tablets and tray 16 for issuing treated tablets. On the basis of the fixed bracket 17 to the control unit 18 with integrated electronic frequency Converter supply voltage. The drum 7 is attached to the bearing 9 by means of radial rods in the form of spokes 19.

The plant operates in the following manner. First pipe 14 attached to the dust suction system, and a pipe 12 to a source of compressed air. Then the rotation of the couplings 4 specify the data set for tablets the angle of the axis of the tumbling drum. During the rotation of the clutch 4 in one side or the other screws inside the poles converge or diverge. To reduce the angle, reduce the height of the rack 3 by the corresponding rotation of the clutch 4, and a height of 2 hours increase by turning the clutch on it in the opposite direction (the position with a smaller angle shown by the dashed line). The rotational speed of the drum set is and the remote control 18. After filling the drum through the hopper 15 of the first batch of tablets include the aspiration system and, as necessary, the compressed air supply.

When you click “start” on the remote control 18, the power supply enters the electronic unit that converts industrial frequency voltage in accordance with the settings on the remote control 18, and supplies power to the electric motor 10. The motor begins to rotate through the coupling 11, the bearing 9 together with spokes 19 and the drum 7 at a speed corresponding to the converted voltage frequency. During the rotation of the drum, the weight of the tablets, overturning, sliding on the mesh surface to the nearest plot pouring tape 13, which stops the movement of pills and sprinkles them, enhancing the interaction with the grid cells. With tablets removes sharp edges, burrs and take pills a smooth shape, suitable for ingestion. Dust and small particles blown off from tablets compressed air from the holes in the pipe 8, pass through the cell drum, settle in the bottom of the housing 6 and vacuumed suction system through pipe 14. Processed tablets roll down to the bottom of the drum and through the tray 16 are poured into the receiving container.

According to the description on the company OAO KBAL “Rotor” developed detailed documentation for installation with the volume of the drum 0,016 ku is metrov for tablets weighing up to 1.5 kg The unit can be used as part of a process line in conjunction with a rotary machine pressing tablets (see our patent No. 2165851 invention “Rotary tablet machine”). Comparison with the installation of KILIAN shows that our setting is two times higher, and for the price, at least six times cheaper. Thus, treatment tablets made with domestic equipment will be significantly cheaper than imported generic medicines, which is of great social value.

The above-described technical solution meets the criteria of novelty, non-obviousness and industrial applicability, and therefore proposed to the legal protection of a patent for an invention.
