SU328613A1 - METHOD OF CONTROL OF AIR PERMEABILITY OF CIGARETTES AND THEIR SIMILAR PRODUCTS OF WAVES - Google Patents

Description

The invention is relative to the area of control of products with air-permeable contents and an air-tight wrapper.

There is a method of controlling the airflow of the wrappers of cigarettes and similar products, which consists in the late introduction of the middle part of each of the articles in the lateral direction into the test chamber. At the same time, seals are installed at the same time on the coping sections of the products, closing the chamber and isolating the ends of the products with end holes from it. A pressure differential is created between the cavity of the product and the test chamber, and the extent of this wrapping is determined by the magnitude of this hierarchy.

The purpose of the invention is to improve performance and ensure accurate network control.

For this, one of the ends of the product is introduced into the intermediate chamber, which, for example, via air-monotonous communication with the atmosphere p with the test chamber and creates air flow with a limiting flow rate from the atmosphere through the intermediate and psychological chambers. The change in pressure in the cavity of the product is determined by the pressure variation in the intermediate chamber.

FIG. 1 shows a device for carrying out the proposed method; on fng. 2 is a section along LL in FIG. I; pp

fpg 3 shows a section along .6-B pa of FIG. 2; in fig. 4 - section bb in phpg. one.

The method is confined in a device that includes a transporter 1 with slots) 2 for wickers, a cigarette lighter, a transfer drum 4, in the sockets 5 of which cigarettes are kept under vacuum created in chamber 6, ejectors 7 that convert cigarettes from drum 4 into 8 drum sockets .9.

The test chamber is formed by sockets 8, corus 10 with pipe 11 for connecting an autonomous vacuum system), side parts 12, 13 and pilot tubes, made in the front surfaces 14 and 15 located on the swivel heads 16. 18. Packing pills from the test chamber ends of the cigarettes L.

The side part 12 is a sponge-out groove 19, each of which is connected with one side with a socket 8 near the ends of the cigarette, and on the other hand with a hole 20, which is connected to the intermediate chamber when the drum 9 is rotated: 21. This tube 22 is connected to a converter 23 , which determines the changes: the pressure gives the appropriate electric power. There is also a pneumatic dispenser, made in the air inlet of 24 p and designed for demolition 1) for opening chu1ktv 1 telposti

Converter 23. In addition, in the part 12 is provided with a hole 25, communicated with the atmosphere.

Poor cigarette emitter is made in the form of a drum 26 with sockets 27 and is located in the immediate vicinity of the transfer drum 28 with sockets 29 connected with vacuum chambers 30 and 31. The drum 26 is provided with a side plate 32 with holes 33 located on the same line with sockets 27 of the reel 26 and coinciding with the apertures 34 in the fixed part, 55, when the sockets 27 and 29 are opposite each other. Air to the opening 34 is supplied through the tube 36.

The tube 37 communicates with a hollow cylinder. The core 38, the ends of which have lined openings 39, and the cylindrical part is arranged in such a way as to direct air jets into the end portions of the sockets 8. Part 40 supplies air for cleaning the grooves 19.

The method for controlling the air permeability of cigarettes is carried out in the following manner.

Cigarettes 3, packed into guia.da 2 conveyors /, are inserted in the side 11a11) 111111 to the unhealthy drum 4. Thanks to the vacuum coming through the channels connecting the sockets 5 with the vacuum chamber 6, cigarettes are removed from the conveyor / n when the drum is hoisted 4 in his gnzdah. In front of the transfer zone from the drum 4 to the drum 9, the vacuum is interrupted in cigarettes by means of ejectors 7 that are not inserted into the sockets 8. In this case, seals are installed at the ends of the cigarette, closing the test chamber, and the ends of the cigarettes that isolate it.

Since one of the ends of the cigarette 3 is connected by an opening 20 with an intermediate chamber 21, which is connected with the atmosphere by means of air-moistening through opening 25, and through the grooves 19 with a test chamber, air is created with limited flow from the atmosphere through the intermediate and test chambers. In this case, the pressure change in the internal cavity of the cigarette is determined by the converter 23

by changing the pressure in the intermediate chamber 21.

If the cigarette is of poor quality, compressed air is supplied through the tube 36 when the socket 27 of the drum 26 is against the socket 29 of the drum 28. In this position, the air, having passed through the hole 33, will blow the cigarettes in the axial direction. At the same time, the vacuum from the side of the chamber 30 is not closed.

Quality cigarettes remain in the sockets 29 of the reel 28 and after passing by the drum 26 are held under vacuum by the chamber 31 until they coincide with the sockets 2 of the conveyor 1 when the vacuum is removed and the cigarettes are removed from the device. For stable operation, the tube 37 and the state are supplied with compressed air, removing tobacco particles from the sockets 8 of the drum 9 from the sealing surfaces 14, 15 and 17, 18. This same air, the part 40, cleanses the grooves 19 of the side part 12 .

Subject and d on and e and

The method of controlling the air permeability of ciHapeT and other similar products, encapsulates some of them, which is in turn to be found in the middle of each of the products when feeding it in the lateral pa-rilepia to the enciphering enclosures of the enclosing enclosures, and in one, they are installed in the end sections of the products. mn, creating a pressure differential between the cavity of the product and the test chamber and determining the extent of the air permeability of the casing, but the magnitude of the change in pressure difference in the cavity of the product, In order to ensure the accuracy and performance of the control, one end of the product is inserted into an intermediate cummer, which, in addition, through the device itself, communicates with the atmosphere and the test chamber and creates air flow with a limited flow from the atmosphere through The intermediate and test chambers, and the change in pressure and in the bottom of the product is determined by the pressure in the intermediate chamber.
