Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for recovering tobacco shreds from defective cigarettes.

Methods for recovering shredded tobacco from cigarettes include the method described in Japanese Patent Publication No. 43-23982, in which the paper is crushed with a roller to burst, and the shredded tobacco is then separated by a sieve; As described in Japanese Patent No. 5040, a method is known in which shredded tobacco is removed from the wrapping paper by hitting the cigarette with a plurality of blades while it is falling, and then separated. However, these methods all have 10
Although it is suitable for recovering shredded tobacco from cigarettes that have been cut into 1-cm pieces, it is suitable for collecting shredded tobacco from cigarettes that have been cut into 1-cm pieces. It is discharged at the tip attachment. There has been a problem in recovering shredded tobacco from double-length cigarettes with the filter still attached to the central portion.

An object of the present invention is to provide a method that allows the recovery of shredded tobacco from the above-mentioned cigarettes and also enables large-scale processing.

The method of the present invention will be explained in detail below based on examples. FIGS. 1 and 2 show an embodiment of an apparatus for carrying out the method of the present invention. Reference numeral 1 denotes a cylindrical release cylinder provided in a vertical direction, on the top of which a supply hopper 3 having an air locker 2 and an air introduction part 5 having an air damper 4 are provided, and the other parts are closed by a plate 6. It is. A rotating shaft 8 is provided in the center of the release tube 1 by a bearing 7, and this rotating shaft 8
is a structure driven by an electric motor 9 provided on a plate 6. On the rotating shaft 8, there are distributed discs 1 at appropriate intervals.
0 is provided in the three-stage section, and on each dispersion plate 10, a plurality of dispersion blades 11 standing vertically are provided.
are arranged radially. A chute 12 is provided in the release tube 1 for guiding the workpiece falling from above to the center of each dispersion disk 10.
2 to 6 release plates 13 along the periphery of the distribution plate 10
A plurality of plates are provided concentrically, and an annular plate 15 is provided at the bottom of the release plate 13 so as to be close to the outer peripheral end of the release plate 13. 16 is formed. Each release plate 13
Projections 14 are provided on the top at appropriate intervals in the vertical direction. The surface of the protrusion 14 is rounded to prevent excessive damage to the filter portion. 17 is an outlet chute provided at the bottom of the release plate 1, and 18 is a support of the release cylinder 1. A sieve 20 is provided below the outlet chute 17 via a seal 19 . 2
1 is a sieve screen, 22 is a tobacco cut outlet, 23 is a paper and filter outlet, 24 is a vibration means for the sieve, 25 is a dust-proof hood that covers the top of the sieve, and 26 is a dust removal duct.

The defective cigarettes are supplied from the supply hopper 3 through the air locker 2 into the release cylinder 1, and are dropped by the chute 12 into the center of the upper distribution plate 10. The dispersing disk 10 is rotated by an electric motor 9 at about 800 revolutions per minute, and disperses the cigarettes around it. The cigarettes dispersed by the dispersing blades 11 are rotated along the release plate 13, and during the rotation, the protrusions 14 on the release plate 13 separate the shredded tobacco, the wrapping paper, and the filter section, and the cigarettes move outward through the passage port 16. It is released and is dropped onto the dispersion plate 10 below while rotating on the side wall of the release tube 1 and the surface of the chute 12, and is gradually released while repeating the same action. The swirling motion of the cigarette in the release cylinder 1 can be adjusted by changing the opening degree of the damper and changing the amount of air introduced from the air introduction part 5. When the cigarettes supplied to the release tube 1 are taken out from the lower part of the release tube 1, the cigarette paper and filter section are almost separated from the shredded tobacco, and are separated by a sieve screen 21.
The tobacco shreds are taken out from 2, and the wrapping paper and filter section are taken out from 23.

If the above-mentioned release action is not performed gradually, the filter part will be damaged and the filter fibers will be loosened.
It becomes impossible to separate and is mixed into the recovered shredded tobacco. Therefore, in the present invention, the distribution plate 1
This was achieved by rotating the 0 rotation speed at approximately 800 rotations and repeating this three times. As for the number of repetitions, softer release may be repeated three times or more, or the release cylinder 1 may be made independent for each distribution plate 10.

As mentioned above, the present invention has a crushing effect to the extent that the filter fibers are not loosened, and the present invention has a crushing effect to the extent that the filter fibers are not loosened.
It is suitable for releasing double-length cigarettes and is also suitable for mass processing.

Claims (1)

[Claims] 1. Cigarettes are supplied onto a rotating dispersion disk, and the cigarettes are scattered around using dispersion blades on the dispersion disk, along with a plurality of release plates provided concentrically around the dispersion disk. During the rotation, the cigarettes are released by the protrusions provided on each release plate, and the released cigarettes are taken out from between the release plates, and the cigarettes are removed from the area around each release plate. A method for removing defective cigarettes from defective cigarettes, characterized in that the release procedure of dropping the paper downward along an outer wall provided at appropriate intervals is repeated several times, and then the paper roll or filter part is separated from the shredded tobacco by a separating means. How to collect shredded tobacco.
