Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for releasing defective cigarettes and separating shredded tobacco.

Conventional technologies for releasing and separating defective cigarettes include:
As described in Japanese Patent Publication No. 23982 of 1972, after arranging defective cigarettes, the cigarettes are sent to a crushing roller or cut with a knife to release the cigarettes, and a vibrating sieve machine is used to process the first shredded cigarettes. The tobacco was then passed through a blower several times to be crushed by the blades of the blower, and a second separation of shredded tobacco was performed using a wind separator to separate the shredded tobacco from the cigarette paper and part of the filter.

However, in the conventional method, it is not possible to fully open small-diameter cigarettes or bent cigarettes at the initial stage, and unopened cigarettes are mixed together and sent to the blower stage, resulting in a problem with shredding tobacco. It had the disadvantage that the particle size was crushed.

Furthermore, in the case of cigarettes using filters containing activated carbon, activated carbon powder is mixed into the shredded tobacco when it is crushed by the roller or cut by a knife.

The activated carbon powder mixed in this shredded tobacco is separated by sieving or wind screening, but in the case of filters that have recently been used that contain activated carbon powder and milk protein granules, activated carbon powder and milk protein granules are separated. Since the specific gravity of the protein granules is different, the efficiency of wind separation is poor, and when using a sieve, the grain size of the milk protein granules is large, so there is a problem that the loss of cut tobacco is considerable.

Furthermore, since a process of arranging defective cigarettes in advance is required, there is a limit to the improvement in processing capacity.

The present invention aims to provide a method and apparatus for releasing and separating defective cigarettes, which eliminates the drawbacks of the above-mentioned conventional methods, and the gist thereof is as set forth in the claims at the beginning.

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

In the drawings, reference numeral 1 denotes a rotating cylinder, which is rotatably supported in a lying state with the rear side lowered than the front side in the axial direction.

That is, on the outer periphery of both measuring parts of the rotating cylinder 1, there are driven wheel metals 2.
, 2 are provided, and the driven wheel metal 2 is mounted on each of the front and rear bases 4.
．． They are placed on drive rollers 3a-1, 3a-2 and 3b-1, 3b-2, which are rotatably provided two each on the drive roller 4.

The rotary cylinder 1 is rotated by driving the drive rollers 3a-1 and 3a-2 by the motor 5.

A humidifying cylinder part 1a is provided in the front half of the rotary cylinder 1, and a shredded tobacco separating part 1b is provided in the rear part, and blade plates 1c are provided protruding from the inner surface in the direction of the stabbing blades at appropriate intervals. Ru.

A water spray nozzle 6 using steam as a carrier is provided inside the humidifying cylinder part 1a and introduced from the fixed face plate 1d, and a heating part 7 consisting of a steam jacket 7a and a heat insulation cover 7b is provided outside the humidifying cylinder part 1a. provided.

A 5 mm sieve 1b-1 is provided on the peripheral wall of the separating cylinder portion 1b, and a striking member 8 formed by a rotary blade plate 8a is provided inside.
is provided, and its drive shaft 8b is extended to the outside and driven by another motor (not shown).

8c is a bearing for the drive shaft. The rotary blade plate 8a is provided in a slightly spiral shape, and as the rotary blade plate 8a rotates, air is sent toward the humidifying cylinder portion 1a of the rotary cylinder 1.

A fixed cover 9 is provided on the outside of the separating tube portion 1b, and a belt conveyor 10 for collecting shredded tobacco is installed below the cover 9 and below the chute 9a.

Close to the front end of the rotary cylinder 1, a fixed face plate 1d is provided by a stand 4.

An artificial chute 1d-1 is provided above the fixed face plate 1d, and an exhaust duct 1d-2 is provided above the entrance chute 1d-1.

A scraper-type feeder 1 is provided in the front stage of the inlet chute 1d-1.
1 is placed.

A fixed hood 1e is provided at the rear end of the rotary cylinder 1, and the lower part thereof is a take-out tube 1e-1.

The extraction tube 1e-1 communicates from the duct He-2 to a cyclone (not shown) via a blower (not shown).

The shredded tobacco, wrapping paper and filter portion separated by the cyclone are sent to a known vibrating screener 12.

The sieves of the vibrating sieve machine 12 consist of an upper sieve 12a for separating shredded tobacco from the wrapping paper and the filter portion, and a lower sieve 12b for separating activated carbon powder and the like from the shredded tobacco.

13 is a belt conveyor for conveying the shredded tobacco left on the lower screen 12b and the shredded tobacco from the belt conveyor 10.

In the above configuration, the defective cigarettes introduced from the artificial chute 1d-1 advance in the axial direction while being stirred by the blade plate 1c, and are sent to the spray nozzle 6 in the first half of the rotary cylinder 1.
The wrapper receives heat and moisture due to the hot water from the wall and the heating from the wall surface by the heating unit 7, which wets the entire outer periphery of the wrapping paper and weakens the adhesive strength of the glue.

Note that heating the wall surface prevents the fallen tobacco from adhering to the wall surface and getting wet.

Some of the glue on the wrapping paper whose adhesive strength has weakened will peel off even with the impact of agitation, but by being positively impacted by the impact member 8 provided in the rotating cylinder 1, some of the glue will be released and cut into shredded tobacco. release.

The loosely fallen shredded tobacco is removed from the sieve 1b of the separating tube portion 1b.
-1 passing through the belt conveyor 1 outside the rotating cylinder 1
Since the released shredded tobacco is discharged to zero, the released shredded tobacco is less likely to be repeatedly stirred or hit by the striking member 8, and the particle size of the shredded tobacco is not impaired.

In order to prevent the sieve 1b-1 from being wetted by the spray from the humidifying cylinder portion 1a, the wind generated forward by the exhaust duct 1d-2 and the rotary vane plate 8a effectively acts.

Note that the chipping paper wrapped around a portion of the filter is waterproof and maintains its original shape even after the glue on the wrapping paper has peeled off, thereby preventing activated carbon powder and the like from getting into the shredded tobacco on the belt conveyor 10. Ru.

A portion of the filter, which is integrated with the opened wrapping paper or chipping paper, remains in the sieve and advances toward the outlet of the rotating cylinder while being agitated and struck.

The shredded tobacco that has passed through the sieve 1b-1 is collected by a fixed cover 9 and a chute 9a, and then collected by a belt conveyor 10.

The unreleased shredded tobacco remaining at the base wrapped in the tipping paper is sent to the blower through the take-out tube 1e-1 and the duct He-2 together with the wrapping paper or a part of the filter integrated with the tipping paper. It is crushed by feathers and sent to a cyclone.

The shredded tobacco, paper, filter, etc. separated from the air here are sent to a vibrating sieve machine, where only the shredded tobacco is separated and recovered.

The influence of the particle size crushing of the shredded tobacco and the mixing of activated carbon powder, etc. in the blower is small because the amount of shredded tobacco to be processed is smaller than that of conventional processing methods.

As described above, the present invention is based on separating the shredded tobacco by releasing some of the glue of the wrapping paper, so the formation of paper waste is extremely small and the shredded tobacco can be easily separated. Since it can be separated at an early stage, deterioration in the particle size and quality of cut tobacco can be prevented.

In addition, in the present invention, changes in the shape and dimensions of defective cigarettes are not related to the function, so it is easy to respond to diversification of brands, dimensions, and standards, and mass processing is possible. Furthermore, it has features of simple structure and easy maintenance.
