Definitions

  • the present disclosure relates to a cleaning unit used in tobacco industry machines, for removing contaminations from a train of rod-like elements, a tobacco industry machine for producing multi-segment filter rods and a method for cleaning a train of rod-like elements.
  • Tobacco industry products such as cigarettes, may comprise segment filters with various filtering materials such as activated charcoal in a form of a loose granulate located between neighboring segments of a solid form.
  • a segment with activated charcoal can be formed by placing the charcoal between the neighboring solid segments, which typically have a form of rod-like elements having filtering properties or rod-like elements having non-filtering properties, for example comprising aromatic capsules.
  • Manufacturers of filters comprising charcoal or other granulate material aim for placement of portions of the loose material such that the segments neighboring a compartment for granulate materials and other segments in the train of segments are not contaminated with this material.
  • manufacturers expect that the granulate material does not get in between side edges of a wrapper which are joined with glue.
  • a US patent US3482488 discloses a device for removing contaminations from rod-like elements by means of a rotating brush.
  • a drawback of this solution is a low cleaning efficiency.
  • a PCT application WO2016139198 in the name of the present applicant, discloses suction nozzles arranged on both sides of a moving train of segments.
  • the aim of the present invention is to provide a device for producing multi-segment filter rods comprising loose material, wherein particles of the material, which are not placed in compartments between solid segments or are lifted from the surface of the segments, are prevented from displacing in the direction of movement of the train of segments, i.e. that they are prevented from displacing between the consecutive assemblies of the device or zones in which consecutive operations of a filter rods production process take place.
  • a cleaning unit for tobacco industry machines a machine for tobacco industry for producing multi-segment filter rods and a method for cleaning a train of rod-like elements during production of filter rods in a tobacco industry machine, according to the appended cliams.
  • an uncontrolled displacement of the contaminations from the cleaning zone is limited by application of an outlet partition at an outlet of the cleaning zone, above the train of rod-like elements, comprising a passage, through which the covering elements pass.
  • the solution according to the invention provides very efficient cleaning of the rod-like elements while maintaining a high degree of filling of the compartments with the loose material.
  • Figs. 1 and 2 show fragments of examples of continuous multi-segment rods CR1 and CR2 formed from trains of rod-like elements (segments) S1, S2 and SC respectively, prepared during production, formed by the unit according to the invention, wherein the segments are wrapped in a wrapper 101.
  • the segments S1 and S2 have a solid shape, typically cylindrical, whereas the segment SC is formed from a loose material 102 which is located between the segments S1 and S1 or between the segments S1 and S2.
  • the presented continuous rods are cut into multi-segment rods.
  • Fig. 3 shows an example of a multi-segment rod R2 produced from the continuous multi-segment rod CR2.
  • Fig. 4 shows schematically a fragment of a machine for producing multi-segment filter rods.
  • the machine comprises a feeding unit 1, which is configured to arrange the rod-like elements S1 and S2 as a train ST1, wherein the rod-like elements S1 and S2 are transported in a substantially preset spaced relationship.
  • the rod-like elements S1 and S2 are fed onto a garniture belt 5.
  • a wrapper such as a wrapping paper, is fed on a transporter of the garniture belt 5 and the elements S1 and S2 are placed on the wrapper 101.
  • a filling unit 103 for supplying the loose material 102, for example activated charcoal, in order to form the segment SC.
  • the train ST2 of the rod-like elements S1, S2 and SC that moves on the garniture belt 5 belt is wrapped in the wrapper 101 by a garniture unit 6, wherein the edges of the wrapper 101 are lifted on a distance where loose material is filled and cleaned.
  • the garniture belt 5 typically forms a part of the garniture unit 6.
  • a cleaning unit 104 for removing contamination of loose material from the rod-like elements i.e.
  • the produced continuous rod CR is transported further and, after the wrapper 101 is glued in the garniture unit 6, it is cut by a cutting head 8 into individual multi-segment rods R.
  • Fig. 5 shows an enlarged view of a fragment of a machine for producing filter rods.
  • the train ST1 of rod-like elements S1, S2 passes through a filing zone Z1 for feeding the loose material, and next as a train ST2 of the rod-like elements comprising also the loose material, passes through a cleaning zone Z2 and through a garniture zone Z3 for forming a continuous filter rod.
  • Fig. 5 presents consecutive steps of a process of feeding the loose material 102 to the compartments 105 in the filling zone Z1, wherein the filling unit 103 for supplying the loose material may be constructed in a way as disclosed in the PCT application WO2016139198 (in the name of the present applicant) or according to other prior art embodiments, such as disclosed in US3545345 , US3623404 , DE1432720B2 , EP0568278B1 .
  • Fig. 5 shows only examples of pockets 103A of the filling unit 103.
  • the cleaning unit 104 located next to the filling unit 103, is equipped with covering elements 10 mounted on a chain transporter 15, shown in fig. 6 , which is equipped with two chain wheels 16.
  • the covering elements 10 may have a form of elements as disclosed in PCT application WO2016139198 (in the name of the present applicant).
  • the covering elements 10 on a fragment of their moving trajectory move linearly in parallel to the displacement direction T, which is the direction of movement of the train ST1, ST2 of the rod-like elements, wherein additionally on a certain distance, they move vertically, transversally to the direction of displacement T in order to approach the compartment 105 filled with the loose material 102, which can be realized by means of a plain linear bearing, while the figure does not show a mechanism for realization of this movement.
  • FIG. 7 shows the covering element 10 having a thin-walled covering part 10A, which covers the compartment 105.
  • the brush 11, 11' is a contaminations sweeping element.
  • a cleaning part 11A (bristles) of the brush 11, 11' touches the side surface of the element S2 (in the presented step of movement of the covering element 10).
  • the number of brushes 11, 11' in the cleaning zone Z2 may be provided according to the needs.
  • a suction nozzle 12 which may have a plurality of openings or one longitudinal opening located in parallel to the train ST1 just above elements S1, S2 such that the covering parts 10A of the covering elements 10 can move below the nozzle 12, as shown in fig. 9 .
  • the cleaning element may also have a form of a compressed air nozzle, which removes contaminations of the side surface of the elements S1, S2, by blowing them out.
  • Fig. 10 shows two compressed air nozzles 17 and 18, which are directed towards recesses formed by the side surfaces of the rod-like elements S1 and S2 and the wrapper 101.
  • the compressed air nozzles 17 and 18 may be directed perpendicularly to the direction of movement of the rod-like elements, or at an angle ⁇ with respect to this direction as shown in fig. 5 , wherein preferably the angle ⁇ is in the range from 30° to 60°, and for example is equal to 45°.
  • Fig. 11 shows another embodiment, wherein the compressed air nozzle 19 passes through the suction nozzle 12.
  • the compressed air nozzle 19 is directed towards the recess between the element S1, S2 and the wrapper 101. Locating the outlet of the compressed air nozzle 19 within the inlet of the suction nozzle 12 (in principle within the inlet of the suction element) causes additional air turbulences, which enhance lifting of the contaminations from the surface of the rod-like elements S1, S2.
  • the cleaning element may have a form of an element made of soft plastic covering an edge for removing the contaminations.
  • the plastic cleaning element may be fixed or may be rotatable.
  • the train ST2 leaving the cleaning zone Z2 is prepared for forming the continuous filter rod CR from the train, which is realized in the garniture zone Z3.
  • the garniture zone Z3 there is a glue nozzle 13 and guiding elements (not shown in the drawing for clarity, but known from the prior art) for bending the edges of the wrapper in order to join these edges and glue them in order to form a continuous filter rod.
  • Filling the chamber 105 with the loose material 102 from the pocket 103A may result in that not the whole amount of loose material is transferred to the chamber 105.
  • a portion of particles, which have certain velocity, may rebound from the rod-like elements S1, S2 or from the wrapper 101, and subsequently fall onto the surface of the elements S1, S2, wherein the falling of the particles of the loose material 102 may occur in any location, for example just before gluing of the edges of the wrapper.
  • the problem of contaminations displacement may be defined as uncontrollable displacement of the contaminations between the filling zone Z1, the cleaning zone Z2 and the garniture zone Z3 for forming the rod.
  • the outlet partition 34 located on the side of the garniture zone Z3 (at the outlet from the cleaning zone Z2), is intended to limit the uncontrolled displacement of the particles of the loose material from the cleaning zone Z2 to the garniture zone Z3.
  • the inlet partition 24 is located on the side of the filling zone Z1 (at the inlet to the cleaning zone Z2) and is intended to limit the uncontrolled displacement of the particles of the material from the filling zone Z1 to the cleaning zone Z2.
  • the outlet partition 34 and the inlet partition 24 may be similar to each other.
  • the outlet partition 34 and the inlet partition 24 may be formed as a single part or as multipart partitions.
  • Fig. 7 shows an exemplary embodiment in which the inlet partition 24 is a two-part partition consisting of parts 24A and 24B. Between the parts 24A and 24B there is a passage 25, through which the covering elements 10 may pass.
  • fig. 8 shows an embodiment in which the outlet partition 34 is also a two-part partition and consists of parts 34A and 34B. Between the parts 34A and 34B there is located a passage 35, through which the covering elements 10 may pass. In the embodiment shown in fig.
  • the inlet partition 24 is located in front of the brush 11 and the outlet partition 34 is located behind the brush 11'.
  • the brushes 11, 11' can be located in the passages 25, 35.
  • the passage 25, 35 is effectively narrowed in such a way that there is only space for the passage of the covering element 10.
  • the partitions 24, 34 may have surfaces arranged obliquely (at an acute angle) with respect to the direction of the movement T of the train ST2, owing to which particles of the contaminations may be rejected aside, outside the track of movement of the train of the rod-like elements.
  • the partitions 24, 34 may be flat or arched shaped. In fig.
  • the inlet partition 24' is flat and arranged askew while the outlet partition 34' is arched and arranged askew.
  • the end partition 44 is located at the inlet to the garniture zone, just in front of the glue nozzle 13 in the region where the edges of the wrapper 101 are bent towards each other before gluing them. In the lower edge of the end partition 44 there is a notch 20 for receiving the edge of the wrapper 101, as shown in fig. 12 .
  • a shield partition 54 (indicated by dashed line in fig. 6 ), the main surface of which is located in parallel to the direction of the movement of the train ST2, i.e.
  • the shield layer 54 prevents the contaminations displacement to the segments S1, S2 just before the initialization of the process of wrapping the wrapper 101.
  • the presented embodiment utilizes an initial partition 14 at the outlet of the filling zone Z1, between the filling zone Z2 and the cleaning zone Z2, which is intended to protect from the displacement of the contaminations outside the filling unit 103 in the direction of the cleaning unit 104.
