Description

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

  A tobacco industry product, such as a cigarette, may comprise a segment filter having a variety of filtering materials, particularly bulk materials, such as activated carbon in the form of loose granules, located between adjacent segments in solid form. Segments with activated carbon can be formed by placing charcoal between adjacent solid segments, where adjacent solid segments are typically rod-like elements with filtering properties (eg segments made of acetate) or unfiltered It has the form of a rod-like element that has properties (eg, a paper pipe or other element made of plastic). The manufacturer of a filter containing charcoal or other granulated material aims to arrange parts of the bulk material so that there is as much space between the solid segments as possible, preferably 100% filling. . In such a filter, the smoke passes through the filtering material and unwanted substances contained in the smoke are filtered. In filters where the space between solid form segments is not sufficiently filled with bulk material, smoke can bypass the filtering material and pass through the empty space present in the filter. Furthermore, such a filter tends to deform in the region filled with the bulk material.

  U.S. Pat. No. 4,161,602 discloses a device for compacting a filtering segment containing charcoal granules. One of its drawbacks is that the segment is deformed by a pin that pushes the inner part of the segment made of filtering fibers into a charcoal segment that is not fully filled, such as to remove empty space It is.

  U.S. Pat. No. 6,656,412 discloses a device for increasing the degree to which the spaces located between the segments are filled with granules. The granulate is introduced into the two stations and is pushed into the space between the segments after each introduction. One disadvantage of such a solution is that it contaminates the product with particulates and dust. Furthermore, such a solution occupies a lot of space in the machine, and so its application is problematic in modern machines that are expected to have a small size.

  European Patent Application No. 1293136 discloses a manufacturing machine for the tobacco industry, producing a continuous covered cylindrical length of hard filter material or tobacco, joined together by curved guide surfaces. A format unit having a side guide surface; The guide surface forms a profile on a plane perpendicular to the direction of material movement through the unit. At least one side guide surface is asymmetric before it reaches a vertical orientation.

  U.S. Pat. No. 4,185,645 discloses that cigarette filter units are made in long strips with alternating portions of fibrous and pourable filter material. The fibrous parts are first attached to the covering strip at spaced apart intervals, and the covering strip is actually wrapped tightly around the fibrous part, into the regular empty spaces and spaces between the fibrous parts. A cylinder having a plurality of openings is formed. In a special unit, air is extracted from these spaces, so that when the space enters a chamber containing filter material that can be poured, the space sucks in the material and completely fills the space. Excess filter material is brushed from the filter unit and a sealing strip is applied to the opening.

  There is a need to provide a device for manufacturing a multi-segment filter rod having segments filled with bulk material, the segments being filled as many as possible, preferably at least close to 100%. Furthermore, there is a need to provide a solution that does not cause significant soiling of the rod with bulk material.

Fig. 3 shows an exemplary continuous multi-segment rod segment with segments suitably filled with bulk material. 1 schematically shows a piece of a machine for manufacturing a multi-segment filter rod. AA sectional view of a garnish portion is shown. BB sectional drawing of a garnish part is shown. A CC sectional view of the garnish portion is shown. Fig. 4 shows the arrangement of the longitudinal axes of the parts of the garnish duct relative to one another. The arrangement | positioning with respect to each other of the bus-line of the part of a garnish duct is shown. The position of the element covering the compartment filled with the bulk material in the area to reduce the compartment volume is indicated. The position of the element covering the compartment filled with the bulk material in front of the area to reduce the compartment volume is shown. The position of the element covering the compartment filled with the bulk material behind the area to reduce the compartment volume is indicated. A CC sectional view of the garnish portion is shown.

  FIG. 1 shows a fragment of an exemplary continuous multi-segment rod CR1 formed from a row of rod-shaped elements S1 and unfilled segments SC1 formed by a known device, It is wound with the winding material 101. The segment S1 has a solid shape that is typically cylindrical, while the segment SC1 is formed from the bulk material 102 located between the respective segments S1.

  FIG. 2 shows an exemplary continuous formed from a row of rod-like elements S1, S2, and SC2 (or alternatively, only S1 and SC2) formed by the device presented herein. A fragment of a multi-segment rod CR2 is shown. Segments S1, S2, and SC2 are wound with wrapping material 101 to form a continuous rod and subsequently cut into multi-segment rods as shown in FIG. The machine 1 comprises a supply unit 2 configured to arrange the rod-like elements S1, S2 as a row ST1. The rod-like elements S1, S2 are transported in a substantially spaced relationship which is set in advance. The rod-like elements S1, S2 are fed to a garniture belt 5 which moves in a duct 9 along a garniture bar 7 (alternatively called the lower garniture part), in which the end of the winding material 101 and the elements S1 and S2 The front side forms a compartment 3 in which the bulk material 102 is fed from the filling unit 103 and forms a segment SC filled with the bulk material. A row ST2 of rod-like elements S1, S2 and SC moving on the garnish belt 5 is wound with a wrapping material 101 by the garnish device 6. Removes dirt from the rod-like elements, i.e., particles of the bulk material that fall on the surfaces of the rod-like elements S1 and S2 when the bulk material is supplied from the filling unit 103 in the previous step. Therefore, the cleaning unit 104 can be located next to the filling unit 103. The manufactured continuous rod CR is further transported, and after the wound material 101 is bonded by the bonding nozzle 4 and the garniture device 6, it is subsequently cut into individual multi-segment rods R by the cutting head 8. .

  FIG. 4 shows an AA cross section of the garnish bar 7 with the garnish belt 5, on which the wound material 101 is located, on which the rod-like elements S1, S2 are located and the bulk material 102 is on the rod-like element S1. , S2 has already been supplied. In this manufacturing stage, the wound material 101 is formed into a U shape by the garnish belt 5. The diameter D1 of the garnish bar 7 at the position where the bulk material 102 is supplied is greater than the sum of twice the diameter of the rod-like element S2 and the thickness T of the garnish belt 5. The thickness T of the garnish belt 5 is preferably between 0.2 and 1.5 mm. It is intended to receive more bulk material 102 in the compartments between the rod-like elements, so that it is possible to reduce the volume of the compartment filled with the bulk material 102 in a subsequent manufacturing stage. . Reducing the compartment volume is achieved by reducing the diameter of the garnish duct 9 in the garnish bar 7 (in which the garniture belt 5 with segments S1, S2 and loose material is guided) from dimension D1 to dimension D2. . The diameter dimension D1 of the garnish duct 9 is defined to prevent particles of the bulk material 102 from falling between the segments S1, S2 and the wound material 101. The difference in values of the dimensions D1 and D2 depends on the type of material from which the segments S1, S2 are made, the type of bulk material 102 and the degree to which the bulk material 102 fills the compartment. Preferably, the difference in values between dimensions D1 and D2 is not greater than the average size of the particles of bulk material 102. Preferably, the difference between the diameters D1 and D2 is 0.2 mm to 1 mm, more preferably 0.2 mm to 0.5 mm or 0.2 mm to 0.3 mm. Furthermore, the second diameter D2 can be 1% to 5%, preferably 2.5% to 3% smaller than the first diameter D1. The reduction of the diameter of the garnish duct 9 is realized over a certain distance L, which can be equal to 30 mm to 100 mm, preferably 40 mm to 90 mm. The dimension D2 is preferably equal to the sum of the diameter of the rod-shaped element S2 and the thickness T of the garnish belt 5 twice.

  FIG. 5 shows the position where the diameter of the garniture duct 9 is reduced to dimension D2 and the section filled with the bulk material 102 is covered from above by the cover element 10 of the cleaning unit 104.

  The pressing surface 10a of the cover element 10 contacts the bulk material 102 accumulated in the continuous section between the rod-like elements S1, S2. The pressing surface 10a can be made of a material that allows air to pass through or a material that cannot pass through, depending on the type of bulk material. The cover elements 10 are elastic, for example they can be made from a rubber or sponge-like material. Furthermore, the cleaning unit 104 is equipped with a suction element 12, preferably a suction nozzle, that supplies a negative pressure to the zone where the cover element 10 contacts or confines the bulk material. The suction element 12 removes dirt from the rod-like element, i.e., in the above-mentioned stage, in other words, when the bulk material is supplied from the filling unit 103, the bulk material falls on the surface of the rod-like elements S1 and S2. The particles are intended to be removed.

  FIG. 6 shows a garniture device 6 comprising a garniture bar 7 and an upper garniture part 11 having segments S 1, S 2 and a forming part 11 a for winding the bulk material 102 with a wrapping material 101. After transporting the compartments with segments S1, S2 and the bulk material 102 to the part of the garniture bar 7 having a reduced diameter D2, the bulk material 102 is concentrated in the reduced compartments between the segments, which Enhance the quality of filling. The portion of the garniture duct 9a is a portion having a larger diameter D1, and is located on the inlet side of the garniture duct 9. The portion of the garniture duct 9b is a portion having a smaller diameter D2, and is located on the exit side of the garniture duct 9. Between the portions 9a and 9b of the garnish duct 9, there is a transition portion 9c of the garniture duct 9. As shown in FIG. 7, the longitudinal axis X of the garniture duct 9 is identical to the axes X1, X2, X3 of the portion of the ganture duct having the larger diameter 9a, the transition portion 9c, and the portion of the duct having the smaller diameter 9b, respectively. I can do it. As shown in FIG. 8, another embodiment is possible in which the longitudinal axis X of the garnish duct 9 does not coincide with all longitudinal axes X1, X2, X3 of the portions of the garniture ducts 9a, 9c, 9b.

  The portions of the garniture ducts 9a, 9c, 9b have buses Y1, Y3, Y2, respectively, arranged in parallel to one another on one common plane Z. Furthermore, it is advantageous if the bus bar Y1 of the part of the garniture duct 9a having a larger diameter, the bus bar Y2 of the transition part of the garniture duct 9c and the bus bar Y3 of the part of the garniture duct 9b having a smaller diameter coincide with each other.

  FIG. 9 shows an example of the arrangement of the cover elements 10 of the compartments filled with the bulk material 102 in the area of the top view, in the region where the volume of the compartments between the segments S1, S2 is reduced. The section with segments S1, S2 and the bulk material 102 together with the wound material 101 placed on the garnish belt 5 is moved downstream towards the cutting head in the garnish duct 9 of the garnish bar 7. At the location where the bulk material 102 is fed into the compartment between the segments S1, S2, the diameter of the garniture duct is equal to D1, which is then gradually reduced in the part L until the diameter dimension is equal to D2. The While reducing the diameter of the garnish duct 9, the bulk material 102 is concentrated, the filling of the compartment is increased and the bulk material is lifted slightly towards the top of the compartment. Furthermore, a cleaning unit 104 is arranged in part L, in which the cover element 10 covers the bulk material 102 from above and at the same time pushes it in the direction towards the inside of the compartment, concentrating on the top surface of the compartment with the bulk material 102. Shape. When the cover element 10 covers the bulk material 102, the dirt of the bulk material from the rod-shaped element is removed by the suction element 12. The cover element 10 prevents the rose material rising due to the narrowing of the garnish duct from rising above the upper ends of the segments S1, S2.

  The cleaning unit 104 may also be located in front of the portion L where the diameter of the garniture duct 9 is reduced, as shown in the second embodiment in FIG. In this example, the dirt of the bulk material generated in the stage of filling the bulk material 102 in the filling unit 103 is removed by the cleaning unit 104. The bulk material 102 supplied to the compartment between the segments S1, S2 is first concentrated and shaped by the pressing surface 10a of the cover element 10 from above. Subsequently, the first shaped bulk material 102 together with the segments S1, S2 and the winding material 101 is conveyed downstream by the part L along the garnish duct 9 of the garniture bar 7, in which the diameter of the garniture duct 9 is It is reduced from D1 to D2, which additionally results in an increase in bulk material 102 and an increase in volumetric filling of the compartment.

  Another embodiment in which the cleaning unit 104 is located behind a portion L that reduces the diameter of the garnish duct 9 is shown in FIG. The advantage of such a solution is that after the diameter of the garnish duct 9 is reduced to dimension D2, the bulk material 102 in the compartment is shaped such that its surplus is pushed upwards, and the compartment with the bulk material 102 is The bulk material 102 covered from above by the pressing surface 10 a of the cover element 10 and located outside the covered region is to be removed by the suction element 12.

  FIG. 12 shows a CC cross section of the garnish bar 7. The figure shows a garniture device 6 comprising a lower part, in other words a garniture bar 7 and an upper garniture part 11, which is used to wind the rod-like elements S 1, S 2 and the bulk material 102 with a wrapping material 101. This process cleans the dirt on the upper surface of the rod-like element after the segments S1, S2 of the compartment 3 with loose material have passed through the parts of the ducts 9a, 9c and where the garnish duct 9 has the final diameter D2. Will be executed later. With a continuous multi-segment rod formed in this way, defects in segment CR2 (which may result from not being fully filled with bulk material 102) are avoided.
