Description

FIELD OF THE INVENTION [0001] The present invention relates to a multi-segment filter rod,

The present disclosure relates to a packaging apparatus, a machine for manufacturing a multi-segment filter rod, and a method for manufacturing a multi-segment filter rod.

Tobacco industrial products, such as cigarettes, may include segment filters with loose materials, such as activated carbon in the form of loose granules, which are positioned between adjacent segments of the solid form, especially the various filtration materials. Segments with activated charcoal may be used in a variety of ways, including rod-like elements (e.g., segments made of acetate) that typically have filtration characteristics, or rod-shaped elements that have non- Or other elements made of plastic), in the form of a plurality of solid segments. Manufacturers of filters, including charcoal or other granular materials, aim to place loose parts of the material such that the space between solid segments is filled as much as possible, preferably 100%. In such a filter, the smoke passes through the filtration material, and undesirable materials contained in the fumace are filtered. In a filter in which the spaces between solid shape segments are not sufficiently filled with loose material, the smoke may bypass the filtration material and pass through void spaces present in the filter. In addition, such filters are susceptible to deformation in areas filled with loose material.

U.S. Patent 4,116,060 discloses an apparatus for compressing filtration segments that contain char granules. One of its disadvantages is that the segments are deformed by the fins which push the inner member of the segment of the filter fiber into the charcoal segment which is not sufficiently filled to remove the void space.

U. S. Patent 6,656,412 discloses an apparatus for increasing the degree of filling of granules in a space that is located between segments. The granules are introduced on two stations, and after each introduction, the granules are squeezed into the space between the segments. One drawback of such a solution is the contamination of the product by granules and dust. In addition, such a solution takes up a lot of space in the machine, and therefore its application is problematic in modern machines which are expected to have compact dimensions.

European Patent Application EP1293136 discloses a manufacturing machine for the tobacco industry, comprising a forming unit with lateral guide surfaces joined together by a curved guide surface, producing continuous filterable materials or continuously covered cylindrical lengths of cigarettes do. The guide surfaces profile in a plane at right angles to the direction of material movement through the unit. The at least one lateral guide surface is asymmetric before the lateral guide surface reaches the vertical direction.

US 4,185,645 discloses that cigarette filter units consist of long strips with alternating repeating portions of fibrous filter material and pourable filter material. The fibrous portions are first attached at spaced intervals to a covering strip which is substantially enclosed about the fibrous portions to form openings into the cylinders and spaces with regular void spaces between the fibrous portions. In the special unit, air is extracted from these spaces, so that when the spaces enter the chamber that receives pourable filter materials, the spaces draw in the materials to completely fill the spaces. The excess filter material is swept away in the filter unit, and a sealing strip is attached on the openings.

There is a need to provide an apparatus for manufacturing a multi-segment filter rod, wherein segments with segments filled with loose material are packed as much as possible, preferably at least 100%. In addition, there is a need to provide a solution that does not cause severe contamination of the rods by loose material.

1 is formed from rows of rod-like elements S1 and insufficiently filled segments SC1 formed by known devices, the rod-like elements and segments being surrounded by a seal 101 Lt; RTI ID = 0.0 > CR1 < / RTI > Segments S1 are typically cylindrical in shape, while solid segments SC1 are formed of loose material 102, which is located between the individual segments S1.

Figure 2 shows the rows of bar-shaped elements S1, S2 and segment SC2 (or, alternatively, only element S1 and segment SC2), formed by the device presented herein Segment rods CR2 formed from an exemplary continuous multi-segment rod CR2. The rod-like elements S1 and S2 and the segment SC2 are enclosed within the envelope 101 to form a continuous rod and are subsequently inserted into the multi- Is cut. The machine 1 comprises a feed unit 2 configured to arrange rod-like elements S1, S2, such as row ST1, and the rod-like elements S1, Lt; / RTI > The rod-like elements S1 and S2 are fed to a packing belt 5 moving into the duct 9 along a packing bar 7 (alternatively referred to as a lower packaging part) The front surfaces of the elements S1 and S2 form the compartments 3 and the loose material 102 in the compartment forms a segment SC filled with loose material, . The rows ST2 of the rod-like elements S1, S2 and SC, which move on the packaging belt 5, are enclosed in the envelope 101 by the packaging device 6. When the cleaning unit 104 is moved from the rod-shaped element onto the surface of the contaminants, i.e. the rod-shaped elements S1 and S2, in a previous step, that is when loose material is fed from the filling unit 103, May be located after the charging unit 103 to remove particles of loose material. The manufactured continuous rods CR are further conveyed and after the envelopes 101 are bonded by the adhesive nozzle 4 and the packaging device 6 the continuous rods are successively routed to the individual plural-segment rods R) by the cutting head 8.

Figure 4 shows that the rod-like elements S1 and S2 are placed on the envelope with the wrapper belt 5 on which the envelope 101 is placed, - < / RTI > sectional diagram of the packaging rod 7, already fed into the spaces between the mold elements S1 and S2. In this stage of manufacture, the envelope 101 is U-shaped by the packaging belt 5. The diameter D1 of the packing rod 7 at the position where the loose material 102 is supplied is larger than the sum of the diameter of the rod-like element S2 and the thickness T of the packing belt 5 . The thickness T of the packing belt 5 is preferably between 0.2 and 1.5 mm. This is intended to accommodate a greater amount of loose material 102 in the compartments between the rod-shaped elements, and therefore, in subsequent steps of manufacture, the volume of compartments to be filled with loose material 102 . The reduction in the volume of the compartments is achieved by the fact that the diameter of the packaging duct 9 (in which the bag-like elements S1, S2 and the packaging belt 5 with loose material are guided therein) Is reduced from the dimension D1 to the dimension D2. The diameter D1 of the diameter of the packaging duct 9 is specified to prevent the granules of the loose material 102 from falling between the rod-like elements S1, S2 and the envelope 101. [ The difference in the values of the dimensions D1 and D2 depends on the type of material making up the rod-like elements S1 and S2, the type of loose material 102 and the filling of the compartment with the loose material 102 . Preferably, the difference in values between the dimensions D1 and D2 is not greater than the average size of the loose material 102 grains. Preferably, the difference between dimension D1 and dimension D2 is 0.2 to 1 mm, more preferably 0.2 to 0.5 mm or 0.2 to 0.3 mm. In addition, the second diameter D2 may be 1 to 5%, preferably 2.5 to 3% less than the first diameter D1. The reduction in the diameters of the packaging ducts 9 is effective on a certain distance L, which can be between 30 and 100 mm, preferably between 40 and 90 mm. The dimension D2 is preferably equal to the sum of the diameter of the bar-shaped element S2 and the thickness T of the packing belt 5 twice.

5 shows a position where the diameter of the packaging duct 9 is reduced to dimension D2 and the compartment filled with the loose material 102 is covered from above by the lid element 10 of the cleaning unit 104 / RTI >

The compression surfaces 10a of the lid elements 10 are in contact with the loose material 102 that is accumulated in successive compartments of the rod-like elements S1, S2. The compression surfaces 10a may be made of an air-permeable or impermeable material, depending on the type of loose material. The lid elements 10 are resilient, for example they may be of rubber or sponge type material. In addition, the cleaning unit 104 is provided with a suction element 12, preferably a suction nozzle, in which the lid elements 10 contact the loose material or supply a negative pressure to the area surrounding the loose material. Suction element 12 is configured to remove contaminants from the rod-like element, i. E. On the surface of the rod-like elements S1, S2, in a previous step, i.e. when loose material is fed from charging unit 103, It is intended to remove particles of loose material that are loose.

Figure 6 shows an upper packaging part 11 having molded sections 11a for enclosing the rod-like elements S1 and S2 and the loose material 102 in the envelope 101, ). ≪ / RTI > After carrying the compartments with the rod-shaped elements S1 and S2 and the loose material 102 to the section of the packaging rod 7 with the reduced diameter D2, Type elements, which increases the quality of filling of the compartment. The section 9a of the packaging duct is a section having a larger diameter D1 and is located at the inlet side of the packaging duct 9. The section 9b of the packaging duct is a section with a smaller diameter D2 and is located at the discharge side of the packaging duct 9. Between the section 9a and the section 9b of the packaging duct 9 there is a transition section 9c of the packaging duct 9. The longitudinal axis X of the wrapping duct 9 has a section 9a, a transition section 9c and a smaller diameter of the wrapping duct with a larger diameter, as shown in Figure 7, (X1, X2, X3) of the section 9b of the packaging duct to be provided. The longitudinal axis X of the packaging duct 9 does not coincide with all the longitudinal axes X1, X2, X3 of the sections 9a, 9c, 9b of the packaging duct, as shown in Fig. 8 Other embodiments are also possible.

The sections 9a, 9c and 9b of the packaging ducts have production lines Y1, Y3 and Y2, which are arranged parallel to one another on one common plane Z, respectively. In addition, a production line Y1 of the section 9a of the packaging duct with a larger diameter, a production line Y2 of the transition section 9c of the packaging duct, and a section 9b of the packaging duct 9b having a smaller diameter Are coincident with each other, it is advantageous.

9 shows an example of the arrangement of the lid element 10 for a compartment to be filled with loose material 102 in the area of the compartments between the rod-like elements S1, S2 of decreasing volume, Respectively. The compartments with the rod-like elements S1 and S2 and the loose material 102 together with the envelope 101 arranged on the packing belt 5 are arranged in the packing duct 9 of the packing bar 7 And moves downward toward the cutting head. At the position where the loose material 102 is fed into the compartments between the rod-like elements S1, S2, the diameter of the packaging duct is the dimension D1, and then the diameter of the packaging duct is the diameter Gradually decreases in the section (L) until it becomes the maximum value (D2). While reducing the diameter of the packaging duct 9, the loose material 102 is concentrated and the filling of the compartment is increased, and the loose material is slightly raised toward the top of the compartment. In addition, in the section L, the cleaning unit 104 is located, where the lid element 10 covers the loose material 102 from the top and simultaneously squeezes and concentrates the loose material in the direction of the compartment interior, And the initial molding of the upper surface of the compartment with the loose material 102. When the lid element 10 covers the loose material 102, contaminants of loose material are removed by the suction element 12 from the rod-shaped elements. The lid element 10 prevents loose material rising due to the narrowing of the packaging duct from rising above the upper edge of the rod-like elements S1, S2.

The cleaning unit 104 may also be located in front of the section L where the diameter of the packaging duct 9 decreases, as shown in the second embodiment of Fig. In this example, contaminants of loose material produced in the charging step of the loose material 102 in the charging unit 103 are removed by the cleaning unit 104. The loose material 102 fed to the compartments between the rod-shaped elements S1 and S2 is initially concentrated and shaped from the top by the pressing surface 10a of the lid element 10. [ Subsequently, such initially molded loose material 102, along with the rod-like elements S1 and S2 and the envelope 101, is conveyed downstream, along the packaging duct 9 of the packaging rod 7, The diameter of the duct 9 decreases from the dimension D1 to a dimension D2 which causes an increase in the concentration of the looser material 102 and the volume of the compartment to be decreased volumetrically, Lt; / RTI >

 Another embodiment, in which the cleaning unit 104 is located behind the section L where the diameter of the packaging duct 9 is reduced, is shown in Fig. The advantage of such a solution is that after the reduction of the diameter of the packaging duct 9 to the dimension D2 the loose material 102 inside the compartment is molded so that the surplus of loose material is pushed upward and the loose material 102 are covered from above by the compression surface 10a of the lid element 10 and the loose material 102 which is located outside the covered area is removed by the suction element 12.

12 shows a sectional view taken along the line C-C of the packing bar 7. As shown in Fig. The figure shows the upper packaging part 11, which is used to enclose the lower packaging part, in other words the packaging rod 7, and the rod-like elements S1, S2 and the loose material 102, ). ≪ / RTI > This process is carried out after the compartments 3 with the rod-like elements S1 and S2 and the loose material have passed through the sections 9a and 9c of the duct and after the packaging duct 9 has reached the final diameter After the cleaning of the upper surface of the rod-shaped elements from the pollutants at the position having the predetermined distance D2. In a so-formed continuous multi-segment rod thus formed, defects in the segments CR2 (which may result from being insufficiently filled with loose material 102) are avoided.
