SU37643A1 - Method and device for making tobacco cigarettes from continuous tobacco tow - Google Patents

Description

The present invention relates to cigarette machines for non-piece cigarettes, producing a continuous tobacco string, and its purpose is to provide a device for producing a tobacco string that is interrupted by gaps.

Tubes made of relatively hard paper are placed in these gaps, so that when cutting, cigarettes with a short tubular mouthpiece are obtained, or the cutting point can be chosen so that the part of the cigarette that is taken in the mouth contains a small amount of tobacco, the rest, the main part, It was packed in the usual way. In the latter form of cigarettes, tobacco rubbing is avoided due to the fact that most smokers throw a cigarette without finishing it a third or a quarter because it has become too short.

The subject matter of the present invention is a device for putting tobacco on a cartridge case, a device for dividing a tobacco bundle into separate spaces from a portion, from a mechanism for forming a continuous sleeve and a mechanism for cutting a stuffed sleeve near or between these gaps.

In FIG. 1 shows a longitudinal section of a portion of a cigarette-nib machine; FIG. 2 is the same, a cross-section at the end of A; FIG. 3 is a detail of the part shown in FIG. one; FIG. 4 — a portion of sleeve paper tape rolled up around tobacco to form a continuous tube; FIG. 5-part of the continuous tube of one of the forms made on this machine; FIG. b - a tube of another shape; FIG. 7 is a perspective view of a cigarette from a tube as shown in FIG. 6; FIG. 8 is a schematic view of an apparatus for attaching pieces of thick paper forming the mouthpieces of a cigarette.

The sleeve tape 7 is moved under a device not shown to supply tobacco thereto and receives the tobacco in the usual manner. Zholob2, which guides the liner tape under the tobacco supplying device, has a curvilinear, for example, semicircular section, so that the liner tape leaves the zholob in the form of a paper zholob that carries an equally distributed tobacco along its length. The sleeve with the tobacco then passes to the mechanism shown in FIG. 1, the cat divides the tobacco bundle into chunks of a length, for example, 2 at intervals, for example, 16.u.if. The mechanism for the formation of these gaps may consist of several rake devices 3 and 4 mounted in pairs on

chain conveyor 5. Grabelki have a width approximately equal to the width of the guide chute (Fig. 2) and are so moved that a pair of rakes that are in contact with each other enter the chute from above at point B almost to the very bottom of the chute. During the movement of the rakes in the direction of movement of the sleeve tape with tobacco, they are, with the help of some suitable device, separated from each other. For example, in FIG. 1 rake, reached the point C of the lower branch of the conveyor, divorced by 16 mm. Due to this, the tobacco bundle is divided into portions, separated from one another by projections and 16 mm, after which the rake rises vertically upwards, completely out of contact with the tobacco.

Raising the rake and lowering its 8th guide chute is achieved by raking the treads on pattern 6, and pulling the back rake off from the front one produces a spring 7, which pulls the back rake into a vertical position as soon as piece 6 allows it. The stop 8 serves to hold in the proper position of the rear rake upon leaving it in contact with the guide. After the pair of rabbits leaves the chute, the conveyors lead them around the end roller, and the rakes return to the point B, where the template 8 has such a shape that causes the rakes to converge with the ends as shown in FIG. one.

The rake mechanism is set in motion from the cutting mechanism of the machine, since this will allow both mechanisms to be synchronized so that the tube will be cut into cigarettes at the required points.

The described form for making the gaps in the tobacco bundle is only exemplary, and it is possible, without deviating from the idea of the proposed invention, to make significant changes.

Before feeding the liner tape / “mechanism that poured tobacco on it, this ribbon is glued at appropriate intervals to pieces of relatively thick paper, which, when the tape is folded into a tube, form

mouthpieces. Conventional apparatuses for attaching mouthpieces to cigarettes can be used to glue these pieces of paper.

FIG. 8, the sleeve / passes between the roller 10 covered with glue from the bath 11 and the pressing roller 12, the surface of the roller 10 being provided with recesses or the like for gumming a certain part of the sleeve tape 7.

Thick paper is also fed in the form of ribbons 13 to the cutting mechanism 14 and the cut pieces 9 come into contact with the tape / at the time of cutting. A pair of press rollers 15 presses the pieces of paper 9 to the tape L of the machine passing thereafter into the trough.

The width of the thick paper tape is less than the width of the sleeve paper tape (FIG. 4) so that one edge of the tape 7 can fit on the other.

FIG. 5, the mouthpieces are relatively short, as they enter the sleeve, as shown in FIG. 7, if, however, it is required to make mundane cigarettes, the mouthpieces are made twice as long as shown in FIG. b, and the tube is cut so that the mouthpiece pieces are cut in half.

Empty spaces in a tobacco-filled cartridge tape can be filled with paper tubes, lumps of paper, or absorbing material supplied by any appropriate mechanism.

The subject of the patent.
