Description

The invention relates to the tobacco industry, in particular to methods for processing defective cigarettes and separating tobacco from them.

The aim of the invention is to preserve the quality of the tobacco being cut and to reduce the formation of paper fines.

The method consists in removing the sleeve jacket from the defective smoking articles by tearing it in the gap between the two grooved rolls rotating in opposite directions at different speeds, then the resulting tobacco paper mixture is separated.

The liner jacket is broken between two rollers having a gap size of 0.55 to 0.65 of the product diameter, a ratio of their rotational speed from 1.65 to 1.85, and a length determined by the following relationship:

.1-1, ЗХ1к + (2-5) mm.

where 1K is the length of the smoking article.

FIG. 1 shows an apparatus for carrying out the method; in fig. 2 - the same section.

The device comprises a chamber for forming smoking articles, consisting of upper and lower bars 1, 2, by means of which channel 3 of the format chamber is formed, giving the smoking products their shape and size in cross section, a movable format flexible tape (not shown). located on the lower bar 2 of the channel 3 of the formatting chamber connected with the block of knife heads 4 is transferred to the unit 5 of the quality control of smoking articles; guides 6 and 7, belt conveyors 8 and 9. serving to supply high-quality smoking products for packing and defective products to the tearing mechanism, the tape width of which

equal to the length of smoking articles with a margin of 2-5 mm.

The main mechanism of the device is the mechanism for tearing the sleeve jacket of defective smoking articles, which consists of a body formed of side walls 10, end 11 mounted on a frame 12, from the top 13 and bottom 14 rolls rotating towards each other at different speeds, In this case, the upper roller 13 has a lower rotational speed as compared to the rotational speed of the lower roller 14, the ratio of the speeds of the high-speed roller 14 to the low-speed 13 is 1.65-1.85 fixed to the bearings in the side walls 10 of the core The pus, in which the axis of the upper roll is stationary and the lower one located at an angle of 45 ° relative to the top, is able to move relative to the axis of the upper roll, forming a gap 15 between the rollers 13 and 14, the size of which is 0.55-0.65 of diameter products. The rolls have a grooved surface along their entire length.

The rolls can be rotated from a single drive or from drives for each roll through a system of feeders (not shown).

The high-speed roll is moved by a special drive through a screw mechanism (not shown in the drawing).

To supply defective smoking articles to the roll gap 15, a tray 16 is installed, onto which products are supplied from the quality control unit 5 along the guides 7 and the belt feeding conveyor 9 or from the hopper 17 installed to collect the defective products formed up to the quality control unit by tape pipeline 9.

To remove the separated tobacco and broken sleeve shirts from the tearing mechanism and feed the separating device, a funnel 18 is installed with an outlet 19, on the inner walls of which there are brushes 20 for cleaning the rollers.

The device works as follows.

A format flexible tape carrying tobacco and sleeve paper on its surface moves inside the channel 3 of the formatting chamber, where the tobacco rod is formed, the shape and size of which is determined by the channel 3 of the formatting chamber.

The tobacco rod, having passed through the block of knife heads 4, is cut into separate parts corresponding to the length of the smoking article.

Smoking products after gluing a filter or mouthpiece, if this procedure

It is produced, passed through the quality control unit 5. High-quality smoking articles along the guides 6 and the feeding conveyor belt 8 are fed to the stowage. Defective smoking articles along the guides 7 and the feeding belt conveyor 9 are fed to the tray 16, through which they are transported to the roll gap 15. If defective products are formed, they are assembled into the quality control unit into the hopper 17, from where they are fed to the belt conveyor 9 and the tray 16.

The belt width of the feeding conveyors 8 and 9 is 2-5 mm longer than the length of the smoking article.

Getting into the gap 15 between the corrugated med-rotating 13 and the fast-rotating 14 rollers, all smoking articles are squeezed and due to the difference in the speeds of the corrugated rolls

paper shell shift in different directions and its gap.

When the smoking product is compressed, some tobacco is displaced relative to the sleeve of the jacket;

closer contact between them and additional stresses appear in the paper. The hooking of the paper by the grooved rolls, which have different rotational speeds, contributes to its breaking.

If the ratio of the roll gap 15 to the diameter of the product is less than 0.65, then there is a significant destruction of the tobacco fibers and shredding of the sleeve jacket, which further complicates the process of separation.

laziness of tobacco from paper. If this ratio is made greater than 0.65. then in the material to be processed there are smoking articles with an unbreakable sleeve jacket.

The ratio of the rotational speeds of the fast-rotating and slow-rotating rolls from the rolls 14. 13 should be in the range of 1.65-1.85.

If this is a roll speed ratio

to make less than 1.65, the smoking article can simply be squeezed, deformed, but not broken.

An increase in this ratio in excess of 1.85 results in an increased amount of shredded tobacco fiber and the appearance of a large number of small particles of paper, the dimensions of which are commensurate with the particles of tobacco fiber, which further complicates the process of their separation.

The tobacco thus separated and the broken sleeve liners are led out of the device by means of a funnel 18 through the outflow opening 19 and are fed to the device for their separation.

Using the proposed method of processing defective smoking articles allows preserving the quality of tobacco by preserving its fiber and reducing the formation of hard-to-make paper fines.

Claims (1)

The invention of the method of processing defective smoking articles, including the removal from the last sleeve of the shirt by her 0 five tearing in the gap between the two grooved rolls, rotating in opposite directions at different speeds, followed by separation of the tobacco-paper mixture, which differs in that. in order to preserve the quality of the separated tobacco and reduce the formation of paper fines, the tearing of the sleeve jacket is carried out between corrugated rollers having a gap size of 0.55 to 0.65 of the product diameter, the ratio of their rotation speed being from 1.65 to 1, 85 and the length determined by the following relationship: .1-1.3Хи-К2-5) mm, where IK is the length of the smoking article.
