FIELD OF THE INVENTION This invention relates to a method of making and packaging cigarettes with a filter.

[0002]

2. Description of the Prior Art Cigarettes with filters are manufactured on a filter assembler, for example as described in British Patent No. 2,241,866, the first part of which is spaced at regular intervals. The first row of cigarette portions of the formed cigarettes are joined to corresponding portions of the second row of cigarette portions by a sheet-like joining element at the winding station, hereinafter referred to as a "double cigarette". Is formed. Each double cigarette consists of two cigarette parts separated by a double filter made integrally with the cigarette part by the above-mentioned joining element, the central part of which surrounds the double filter, each end of which has its own cigarette. Surround the end of the tobacco portion.

As also described in the above-mentioned British patent, once the double cigarettes have been formed, they are successively sent to a cutting station where they are cut laterally in half and face each other one by one. Form two rows of cigarettes. That is, downstream from the cutting station, each set of cigarettes formed by cutting a double cigarette is positioned opposite and substantially in contact with each other's filter.

According to the British patent, the two rows of filtered cigarettes are then sent to a spinning station where one row of cigarettes is rotated over the other row and the rolled cigarettes. Tobacco is delivered to the space between two adjacent cigarettes in the other row, 1
It is sent to the output of the filter assembler and from there to the input of the wrapping machine as cigarettes of the same orientation in a row.

In recent years, filter assembling machines have been used as double wrapping machines,
That is, it has become necessary to connect to a machine having two packaging lines or a packaging unit consisting of a pair of packaging machines. That is, the filter assembler had to be connected to a packaging unit having two inputs at a fixed distance.

[0006]

As a method for solving the above problems, the double-row filter assembling machine described in British Patent Nos. 2,201,576 and 2,202,127 can be adopted. However, there is no spinning station at the output to bring the two lines together. In either case, of course, the downstream packaging unit is
It must be designed so that the book inputs can each receive a series of opposing cigarettes.

It is an object of the present invention to provide a method in which an array of cigarettes of the same orientation can be fed simultaneously to two inputs of a packaging unit with only minor modifications to existing single line filter assembly machines. Is.

SUMMARY OF THE INVENTION According to the present invention, cigarette items, each consisting of two cigarette portions joined to a double filter, are continuously fed to a cutting station of a filter assembly machine, one at a time. Forming first and second rows of opposed cigarettes, the first
Rotate the first row of cigarettes away from the second row of cigarettes in the same orientation by rotating the rows of cigarettes in the same orientation as the second row of cigarettes. Provided is a method of making and packaging a cigarette with a filter, which comprises forming two rows of laterally spaced cigarettes.

According to an embodiment of the above method, the two rows of cigarettes are sent to respective outputs of the filter assembler through respective separate passages and then to the side of each dual input packaging unit. Sent to spaced inputs. Non-limiting examples of the present invention are described below with reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Number 1 in FIG. 1 shows a system for producing tobacco items, which has a filter assembly machine 2 and conventional input feeders 6 and 7 laterally separated with respect to lines 4 and 5, respectively. It comprises a packaging unit 3 provided with parallel packaging lines 4 and 5 of the book.

Lines 4 and 5 are channels 8 and 9 connected to devices 6 and 7, respectively, in a conventional manner.
Which feed a collection 10 of filtered cigarettes 11 designated 11a and 11b, respectively, to respective feed transmissions 14 and 15 which form a cigarette group by conventional conveyors 14 and 15, respectively. It is fed to conventional packaging stations 16 and 17, respectively.

As shown in FIG. 1, the filter assembler 2 is fed in a conventional manner with a row of double cigarettes 20 each having two cigarette portions 21 and 22 connected by a double filter 23. First done
An output unit 18 including a roller 19 is provided. The double cigarettes 20 fed to the rollers 19 rotating clockwise in FIG. 1 are sent to a conventional cutting station 24 where they are cut in half and arranged in opposite directions, ie the filters 27 face each other. To form two rows 25 and 26 of cigarettes 11a and 11b that are substantially in contact.

Rows 25 and 26 are from roller 19
As will be described later in detail, the rollers 19 are almost in contact with each other.
And is transferred to a rotation unit 28 composed of a roller 29 that rotates counterclockwise. Once fed to the rollers 29, the cigarettes 11a in row 25 are rotated outwardly, i.e., rotated 180 degrees at a point close to the opposite end of the filter 27, to rotate away from the row 26, and thus the cigarettes in row 26. 11b in the same orientation, but separated from the row 26 by a distance that is about the same as the length of the cigarette 11.

Once rows 25 and 26 have been formed on roller 29, they are transported from roller 29 to roller 30 which is a distance from said roller 29, both in line with roller 29, in lines 31 and 32. With input rollers, rows 25 and 26 are fed to devices 6 and 7 in the input part of lines 4 and 5 of unit 3. Each line 3
1 and 32 conventionally consist of a conventional test unit 33 consisting of rollers 34 in contact with each roller 30,
This sends the cigarette 11 to a conventional device 35, where it is continuously tested for permeability and / or damage and / or breathability, in contact with the roller 34, if necessary, with the roller 34 and the input. A roller 37 located between the devices 6 and 7 and an output roller 38 cooperating respectively.
Excluded at conventional excluding stations around.

As shown in FIG. 4, the outer surfaces of the rollers 29 of the rotating unit 28 are in contact with each other and the central hub 4 of the rollers 29.
Limited to first and second cylindrical surfaces 39 and 40 coaxial with 1. Face 39 has a smaller diameter and is at least twice as long as face 40 joined by annular shoulder 42. At the end of the roller 29 on the surface 39 side, the surface 39
Coaxial with, there is an annular gap 43 which extends on the cam 45 and defines an annular wall 44 which is externally defined by the face 39 on the roller 29. The cam 45 is housed in the cavity 43 and is rotatably coupled to the hub 41 so that when the roller 29 is rotated around the shaft 46 by conventional activation means (not shown), conventional external locking means (not shown). ) Fixed to maintain the angle.

As clearly shown in FIG. 3, the wall 44 is provided with a ring of through holes 47 of substantially cylindrical shape at equal intervals on a surface perpendicular to the axis 46, in the middle of the surface 39, respectively. Has an axis 48 in the plane. Shaft 48 of each hole 47
Is a predetermined angle A with the radius of the surface 39 passing through the center point of the hole 47.
And is inclined forward in the rotation direction of the roller 29 toward the shaft 46. Inside each hole 47 a pin 49 is fitted for rotation and is provided with two annular flanges 50 and 51 for axial locking with respect to the wall 44. The flange 50 is located at the end of the pin 49 protruding into the space 43, and is parallel to the shaft 48 of the pin 49.
4, a radial appendix 52 is provided which fits an eccentric tappet roller 53 which engages an annular groove 55 of the cam 45.

The flange 51 is integral with the middle portion of the pin 49 and has an end portion 56 which projects outwardly of the face 39,
A radial appendix 5 with its free outer end extending from the pin 49 in the diametrically opposite direction of the appendix 52.
Engage with 7. Opposite the pin 49 on the appendix 57, a fixed axial conduit 59 in the pin 49, a number of radial holes 60 in the pin 49, an annular groove 61 formed in the face of the hole 47 in the wall 44 and an axis in the wall 44. The sheet 58 communicates with the suction conduit 63 through the directional hole 62 (FIG. 4) and holds the cigarette 11a.

Together with each roller 53 and each appendix 57, each pin 49 constitutes a device 64, each sheet 58, ie each cigarette 11a, in the idle position shown by the solid and dotted lines in FIG. 180 degrees between the operating positions facing each other. In the idle position, the sheet 58 of the cigarette 11a is on the surface 40
Adjacent to and coaxial with the corresponding sheet 65 formed in the above, where the cigarette 11b is held by suction through a hole 66 connected to the conduit 63. In the operative position, the sheets 58 are still coaxial with their respective sheets 65, but separated therefrom by a distance approximately equal to the length of the cigarette 11.

As shown in FIGS. 3 and 5, the roller 1
Upon receipt of the cigarette 11a from the device 9, the device 64 is set in the idle position and each pair of cigarettes 11a and 11b rolls in their original position, i. Transferred from 19 to roller 29. However, due to the groove 55 design shown in FIG. 5, as each device 64 moves along the cam 45, the pin 49 is gradually rotated (counterclockwise in FIG. 5) to move each appendix 57 outwards 180. Rotate gradually. This is completed before the device 64 reaches the contact point between the roller 29 and the roller 30 and before transferring the cigarette 11a to the roller 30 in line 31 in the conventional manner.
8 is set in the operating position. After that, the sheet 58 is
Return to the idle position before reaching the contact point between the roller 19 and the roller 29.

Therefore, the present invention uses a conventional filter assembler to reverse the operation of a conventional existing rotator and in a very simple manner to orient the cigarettes 11 in rows 25 and 26 in the same orientation. By overlapping a part of the filter assembly machine downstream of the rotating device, the cigarettes can be oriented in the same direction and spaced apart in the axial direction without adding a device.

With respect to the axial spacing of the rows 25 and 26, a value approximately equal to the length of the cigarette 11 shown in the example can be achieved within a given range by varying the position of the shaft 48 for each sheet 58. It can be changed to a desired value. Of course, in this case, each position of the shaft 48 is associated with the lowest angle A so that each appendix 57 does not contact the adjacent appendix 57 when the pin 49 rotates.

In addition, rows 25 and 2 determined by device 64
The axial spacing of 6 is such that, if it is non-zero, the cigarettes in the sheet are axially aligned by a simple conventional guide device (not shown) consisting of, for example, a wedge or guide channel connected to rollers 37 or 38. It is not particularly important as it can be selectively slid in the direction so that the rows 25 and 26 exactly engage the input devices 6 and 7 of the unit 3.
