Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a method for producing filter cigarettes of different sizes.

[0002]

2. Description of the Related Art To produce a cigarette with a filter,
A filter assembling machine is used, which is supplied by a cigarette producing machine with two consecutive cigarette parts which are cut in half laterally by a first blade into two halves. It forms a single cigarette part of.

The single portions of each pair are then axially separated to define a gap into which double the filter is fed, with its ends joined to two single cigarette portions. Form double the amount of cigarettes.

The double filter of each double cigarette is then laterally cut in half by a second blade to form two single-filter cigarettes of the same size.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a method by which two streams of different size cigarettes can be produced in a single filter installation machine of the type described above.

[0006]

SUMMARY OF THE INVENTION In accordance with the present invention, there is provided a method of producing different sizes of filter cigarettes, the method comprising a first cigarette portion each comprising twice as many cigarette portions. Of the elongated elements are laterally cut into two single parts by a first cutting means, the two single parts are axially separated and separated by a second elongated element consisting of a double filter, A method of connecting two elongate elements to form a double cigarette, wherein a second elongate element is transversely cut by a second cutting means to form two single filtered cigarettes.

Non-limiting embodiments of the invention are described below by way of example with reference to the accompanying drawings.

Reference numeral 1 in FIG. 1 is a known type cigarette manufacturing machine, which is provided with a carry-out plate 2 and has a substantially continuous cigarette tobacco rod body (not shown) along the carry-out plate 2. Supplied at a directional speed, the cigarette rod is cut into a continuous section 3 by a known cutting head (not shown).

As is known, the cutting head (not shown) is at such a speed as to produce a portion 3 of a length equal to the total length of the two cigarette-filled portions of the filter cigarette to be produced. Is rotated.

Reference numeral 4 in FIG. 1 shows a filter assembling machine, in which the carry-in roller 5 is, for example, US Pat.
It is connected to the carry-out plate 2 of the machine 1 by a rotary transfer unit 6 of the type described in 303,926. A unit 6 rotating about its axis continuously transfers the part 3 from the carry-out plate 2 into each peripheral seat 7 on the carry-in roller 5, which is known in the counterclockwise direction (in FIG. 1). ) And about an axis parallel to the plate 2 to rotate at a constant angular velocity.

The roller 5 rotating about its axis is part 3
, Which are driven to rotate these parts 3 in the clockwise direction in FIG.
It is continuously transferred into each upper peripheral seat portion 8. The roller 9 abuts the roller 5 and also feeds the part 3 along a circular path where the end of the part 3 contacts the alignment plate 10,
Align accurately in the lateral direction.

Once aligned, the parts 3 are fed by a roller 9 through a cutting station 11, in which a blade 12 cuts each part 3 into two parts 13 and 14,
These parts 13, 14 remain aligned and end-to-end in the seat 8 and substantially contact each other.

As shown in FIG. 1, the roller 9 also
The essential portion of that disclosure is in side-by-side contact with rollers 15 and 16 of an axial separation or spacing unit 17 of the type described in U.S. Pat. No. 4,531,629, which is incorporated herein by reference.

Due to the unit 17 whose rollers 15 and 16 are offset in the height direction, the aligned portions 13 and 14 in each seat 8 are substantially equal to the length of the double filter 18. Axially separated by a distance, and roller 1
It is fed into a seat 19 on a roller 20 which is substantially in contact with 5 and 16 and rotates about its axis in the same direction as roller 9 and at the same surface speed as rollers 15 and 16.

The roller 20 is arranged parallel to the roller 9,
It forms part of an assembly unit 21 of the known type which comprises first and second rollers 22 and 23 and supplies a double filter 18. As shown in FIG. 1, roller 22 is disposed between rollers 20 and 23 in substantial contact therewith,
Rotating around the axis in the opposite direction to the rollers 20 and 23 and at the same surface speed as the rollers 22 and 23, each double filter 18 is provided upstream of the contact point between the roller 20 and the rollers 15 and 16. It is supplied into each seat 19 at the loading department 24.

More specifically, the rollers 22 each double the filter 18 into a substantially central portion of each seat 19 that matches the clearance between the aligned ends of each pair of portions 13 and 14. To each seat 19,
Each double filter 18 defines in seat 19 two empty end portions which are subsequently occupied by respective coaxial portions 13 and 14, so that only double filter 18 is present on roller 20. 1 with two separated parts 13 and 14
One assembly 25 is formed.

These assemblies 25 are carried by the roller 20 of a finishing roller 27 of a finishing unit 27 of the type described in Italian Patent 1,200,229, whose entire disclosure is incorporated herein by reference. Is continuously supplied. The finishing unit 27 is a first for supplying the roller 26 with a number of successive strips 30 each joining the parts 13, 14 of each assembly 25 and the double filter 18.
And second cascade rollers 28 and 29.

The unit 27 also includes an assembly 25 and a band 30.
A roll unit 31 of a known type for continuously receiving and each strip 30 for each double filter 18 and each part 1.
Wrap around the adjacent ends of 3, 14 to form double cigarettes 32 and feed these double cigarettes 32 into each seat 33 on the rollers 34 of the cutting unit 35.

In addition to the roller 34, the cutting unit 35 further comprises a rotary blade 36, which is a roller 3.
4 and cut twice as many filters 18 of each twice as many cigarettes 32 and housed in the same seat 33 with each filter 39 and 40 facing and substantially contacting each other. The two filtered cigarettes 37 and 38 are formed.

Roller 34 is placed in contact with two side-by-side carry-out rollers 41 and 42 to transport cigarettes 37 and 38 to respective seats 43 and 44 on rollers 41 and 42, respectively, and to leave machine 4. To form two separate streams of cigarettes.

According to the embodiment shown in FIGS. 2 and 3,
The blade 12 is laterally offset with respect to the center of the part 3, thereby cutting the part 3 into two parts 13 and 14 of different lengths. In the illustrated example, the blade 12 is biased with respect to the center of the portion 3 by biasing the portion 3 with respect to the roller 9 by the plate 10 to keep the blade 12 flush with the central cross section of the roller 9. According to a modification not shown,
The part 3 is of course centered with respect to the roller 9 by the plate 10 and the blade 12 can be moved laterally as far as necessary with respect to the position in which it is centered with respect to the roller 9.

According to the embodiment shown in FIGS. 2 and 3,
The blade 36 is perfectly centered with respect to the double filter 18, and filters 39 and 40 of different lengths produce filter cigarettes 37 and 38 of the same length.

According to the variant shown in FIGS. 4 and 5, the blade 12 is located centrally with respect to the parts 3 and cuts each part 3 into two parts 13 and 14 of the same length, whereas the blade 36. Is 2
Laterally offset relative to the center of the double filter 18, different lengths of filter 39 and 40 form different lengths of filter cigarettes 37 and 38.

According to the variant shown in FIGS. 6 and 7, both the blade 12 and the blade 36 are laterally offset with respect to the center of the part 3 and the double filter 18, respectively, and of different lengths. The sections 13 and 14 and the respective filters 39 and 40 form filter cigarettes 37 and 38 of different lengths.
