Definitions

  • the invention relates to a device for producing coaxial filters for rod-shaped smoking articles, such as cigarettes.
  • Coaxial filters for rod-shaped smoking articles and in particular for cigarettes are known (eg from the US 3,396,061 A ) and have an inner, formed into a round bar soul, which is surrounded by an outer sheath. Both the inner core and the outer cover are each made of filter tow material.
  • the characteristic of a coaxial filter is that the filter tow material used for the core differs from the filter tow material forming the outer cover, for example, in terms of material, density, stiffness, and the additives contained therein.
  • the permeability, the filtration properties and / or the taste and thus the smoking behavior and / or mechanical properties such as stiffness can be selectively influenced in a desired manner.
  • a device for producing coaxial filters for rod-shaped smoking articles, such as cigarettes with a wrapping device, which is designed to wrap a first filter tow with a second filter tow to form a Koaxialfilterstranges, a first Tow guideway, along which the first filter tow is movable in the direction of its longitudinal extent to the wrapping means, a second Tow Entrysbahn along which the second filter tow is movable in a substantially expanded shape in the direction of its longitudinal extent to the wrapping means, an upstream first interface, of which the first Tow guideway leads to the wrapping device and provided for connection to an outlet-side interface of a first processing unit for processing the first filter tow strip is, an upstream second interface from which the second Tow Equipmentsbahn leads to the sheath means and which is intended to be connected to an outlet side interface of a second processing unit for processing the second filter TertstMails, and a downstream of the wrapping means located third interface, which is for exclusion to a in
  • a device for producing coaxial filters for rod-shaped smoking articles, such as cigarettes with a wrapping device, which is designed to wrap a first filter tow with a second filter tow strip to form a Koaxialfilterstranges a first tow path along which the first filter tow strip is movable in the direction of its longitudinal extension to the wrapping device second tow guide track, along which the second filter tow strip is movable in a substantially expanded form in the direction of its longitudinal extent to the wrapping device, an upstream first interface from which the first tow path leads to the wrapping device and for connection to an outlet side interface of a first processing unit for processing of the first filter tow strip, an upstream second interface from which the second tow path leads to the enclosure device and which is provided for connection to an outlet side interface of a second conditioning unit for processing the second filter tow strip, and a third interface located downstream of the enclosure device for exclusion to an inlet-side interface of a conventional one-lane for further processing a
  • the solution according to the invention allows to a greater extent the use of previously used for the production of simple, so single-layer filter strands components.
  • modules, machines or devices for processing filter tow strips and, on the other hand, the downstream processing device or strand production machine for further processing of the processed filter tow strips into filter strands or filter rods.
  • filter tows eg made from cellulose acetate threads
  • filter tows are removed from a bale, processed by stretching and treating with softener, formed into a round shape and given a desired shape and consistency for further processing to the further processing device or strand production machine, which is made from the processed filter tow strip by wrapping with a wrapping material strip produces a filter strand, which is finally cut into filter rods for cigarettes or other rod-shaped smoking articles.
  • the production of coaxial filters according to the present invention is merely another conventional one Filter processing unit and additionally requires a device according to claim 1 or 2, which is arranged between the filter preparation and the further processing device or strand manufacturing machine and merges two filter tows to form a Koaxialfilterstranges.
  • the use according to the invention of a conventional one-line further processing device or strand production machine originally intended for the further processing of single or single-layered filter tows is economically advantageous, since it makes use of an existing device or machine which, if at all, only needs minor modifications and adaptations. while the provision of a specifically designed device or machine would require a much greater effort, but which is cleverly avoided by the inventive solution.
  • the term "towpath” primarily means the path along which the filter tow moves.
  • the tow guide track may be provided with a web guide, which leads the filter towers supportive.
  • such a track guide is at least not consistently mandatory.
  • the construction according to the invention is particularly suitable for carrying out the device according to claim 1 or 2 as a module with the defined interfaces for integration into a conventional plant intended for the production of simple filter strands. This more fully meets the growing demand for greater flexibility in packaging and use of a filter web.
  • the tow guideways should be substantially one above the other.
  • the first tow guide track in such a way that, at least along a section located downstream and adjacent to the covering device, the first filter tow strip is guided in a substantially round-shaped state.
  • the first filter tow strip already enters the wrapping device as a substantially round-shaped strand.
  • the first Tow Entrysbahn at least one Keilnutrolle, over which the first filter tow is guided.
  • the first tow guide track can have at least one nozzle and / or a funnel through which the first filter tow strip is guided.
  • the wedge roll or nozzle and / or the funnel form a means for deflecting the filter tow strip and at the same time may also serve as a means for rounding the first filter tow strip.
  • the second tow guide track can also have at least one roller over which the second filter tow strip is guided. Since the second filter tow strip is used to form the outer layer or casing for the coaxial filter and is therefore wrapped in the wrapping device from the outside around the then already substantially round shaped first filter tow, the second filter tow along the second tow path is at least initially in a substantially spread Form moves in the direction of its longitudinal extension. Therefore, that roller should preferably be provided with a smooth or slightly concave curved surface.
  • the second filter tow can already be preformed a little by obtaining an at least slight curvature transversely to its longitudinal extension, with which it then runs into the wrapping device, whereby the wrapping process taking place there is somewhat simplified.
  • the wrapping device has a hollow inlet or wrapping finger, which tapers in the conveying direction, through which both filter tow strips are guided together and the second filter tow strip is placed around the first filter tow strip.
  • the preferred wrap-around or wrap-around finger has a cup or funnel shape, the inner surface of which forms a guide for the outer second filter tow and, due to the cross-sectional constriction increasing in the transport direction, causes the second filter tow to move as it progresses through the run-in or wrap-around finger around which at the same time also passes through the inlet or wrapping finger guided first filter tow.
  • the two filter tow strips reach the wrapping device in a superimposed arrangement.
  • the spread or already a little preformed second filter tow should be down, which not only has the advantage that the then coming from above substantially already round-shaped first Filtertowstsammlung by means of gravitational influence comes into contact with the second Filtertowstsammlung, but the spreading or slightly preformed underlying second filter tow also assumes a protective function for the already round-shaped and therefore narrower first filter tow.
  • the processing units are preferably arranged substantially one above the other for a space-saving arrangement, which is particularly suitable when the tow guideways in the apparatus according to claim 1 or 2 are arranged substantially one above the other.
  • At least one section of at least one conditioning unit may be arranged such that the transport of the filter tow strip takes place there approximately in the horizontal or vertical direction.
  • an upper processing unit is arranged so that the transport of the filter trough strip this processing unit takes place approximately in the horizontal direction
  • the lower processing unit is arranged such that the transport of the filter tow strip through this processing unit takes place in an upstream section approximately in the vertical direction and in a downstream section approximately in the horizontal direction.
  • the outlet-side interfaces of this processing device can be arranged one above the other, which is particularly suitable when the tow guideways in the apparatus according to claim 1 or 2 are arranged substantially one above the other.
  • the webs in the processing device can preferably also be arranged substantially one above the other.
  • This filter tow preparation section 2 has a first processing unit 4, which is provided for processing and feeding a first filter tow strip 6.
  • the first filter tow 6 is withdrawn before entering the first processing unit 4 of a filter towers, not shown, and directed via a likewise not shown deflection and Towausbevungsorgan towards the unspecified in the figures inlet of the first processing unit 4.
  • the first filter tow 6 is at least stretched and treated treated with plasticizer accordingly, optionally round-shaped and delivered in a desired shape and consistency via an outlet-side interface 4a from the processing unit 4.
  • the processing facilities used for this purpose are in the Figures 1 and 2 in the first processing unit 4 shown only schematically and also not marked with reference numerals.
  • the first processing unit 4 is arranged horizontally in the illustrated embodiment, so that there takes place the transport of the first filter tow 6 in the horizontal direction.
  • the filter processing section 2 has a second processing unit 8, through which a second filter tow 10 is prepared and made available, such as Figures 1 and 2 also show schematically.
  • the second filter tow strip 10 Before entering the second processing unit 8, the second filter tow strip 10 is drawn off from a second filter bale, not shown, and arranged above the second processing unit 8 deflecting and Towausbungsungsorgan 12, which sits at the upper end of a support arm, not shown in the direction of a closer shown inlet of the second processing unit 8 directed.
  • the second conditioning unit has an upstream first portion 8a and a downstream second portion 8b.
  • these two sections 8a, 8b are arranged and aligned such that the transport of the second filter tow strip 10 through the first section 8a takes place vertically and through the second section 8b overall substantially approximately horizontally, before the second filter tow strip 10 passes through an outlet-side interface 8c the second conditioning unit 8 is output.
  • the second filter tow 10 is prepared in particular by stretching and treating with plasticizer and output in a desired shape and consistency.
  • the processing devices used for this purpose are provided in the two sections 8a, 8b of the second processing unit 8, but not shown in detail in the figures.
  • the first processing unit 4 is disposed above the second processing unit 8 and is in the concrete embodiment shown on the second section 8b of the second processing unit 8.
  • the first portion 8a of the second processing unit 8 is arranged upright at the upstream end of the second portion 8b of the second processing unit 8 and also the first processing unit 4.
  • a two-lane filter preparation device can also be provided, which forms a uniform device in which a filter tow strip is processed and treated separately along two paths in the same way as in the previously described processing units 4, 8.
  • a device 16 which takes over specific functions for a production of coaxial filters and is hereinafter referred to as a transition module.
  • this transition module 16 the two filter tow strips 6, 10 are combined to form a common coaxial filter strand in the manner described in more detail below. Accordingly, for the inventive production of coaxial filters in addition to a further processing unit (eg 4) only requires the mentioned transition module 16, which is arranged between processing section 2 and single-strand machine 14.
  • the first towpath 18 serves to transport the first filter tow 6 and the second towpath 20 to transport the second filter tow 10.
  • the upstream end of the first towpath 18 forms its inlet-side interface 18a and forms the upstream end of the second towpath 20 their inlet side interface 20a.
  • the outlet-side interface 4a of the first processing unit 4 and the inlet-side interface 18a of the first tow path 18 must coincide with respect to positioning and alignment with each other, the same for the connection of the inlet-side interface 20a of the second Tow guideway 20 to the outlet-side interface 8c of the second processing unit 8 applies.
  • the aforementioned interfaces 4a, 8c, 18a and 20a are preferably provided with passage openings for the passage of the respective filter tow strip.
  • the two Tow arrangementsbahnen 18, 20 converge toward a wrapping device 22, which is also included in the transition module 16.
  • the upper first filter tow 6 is enveloped from below with the second filter tow 10 in the illustrated embodiment. Therefore, the first filter tow 6 should be rounded at the latest when entering the wrapping device 22 substantially.
  • the circular shaping of the first filter tow strip 6 can already take place in the first processing unit 4; Alternatively or additionally, however, it is also conceivable that the round shaping of the first filter tow strip 6 within the transition module 16 by means of corresponding processing devices, not shown, along the first tow path 18 perform.
  • the lower second filter tow strip 10 should reach the wrapping device 22 in a substantially expanded form or optionally in a shape slightly curved transversely to its longitudinal extent. Therefore, a round shaping of the second filter tow strip 10 in the second processing unit 8 does not take place.
  • the first conditioning unit 4 lies above the second conditioning unit 8
  • the first tow guide track 18 is also necessarily arranged above the second tow guide track 20 within the transition module 16.
  • the first filter tow 6 is transported along the first tow guide track 18 from above toward the second tow line strip 10 passed beneath the second tow guide track 20 until the first filter tow 6 in the shroud device 22 comes to rest on top of the second filter tow strip 10 then be wrapped by the second filter tow 10.
  • the relative arrangement of the two filter tow strips can also be interchanged as required, so that the upper filter tow strip is spread substantially flat and is moved from above in the direction of an essentially already circularly shaped filter tow line located underneath that the round-shaped filter tow is wrapped with the substantially flat-spread filter tow from the top.
  • the wrapping of the first filter tow strip 6 with the second filter tow strip 10 results in a common coaxial filter strand, the inner core of which is formed by the round shaped first filter tow 6 and the outer wrapping layer of the second filter tow 10.
  • the coaxial filter strand thus produced exits the cladding device 22 through an outlet 22a and is then conveyed to the single strand machine 14.
  • the outlet 22a of the shroud 22 simultaneously forms an outlet-side interface for the transition module 16 and must match the single-strand machine 14 for proper transfer of the coaxial filter strand into the single-strand machine 14 for positioning and alignment with the inlet-side interface of the web.
  • These interfaces are also preferably provided with corresponding passage openings for the passage of the Koaxialfilterstranges.
  • the coaxial filter strand produced from the filter tows forms only a single strand which moves along the path in the downstream single-strand machine 14 and further processed is.
  • This operating state is shown schematically in the block diagram of Fig. 3 shown.
  • the web 14a of the single-strand machine 14 is schematically recognizable, which is connected with its inlet-side interface 14aa at the outlet-side interface 22a of the transition module 16 or the outlet of the cladding device 22.
  • the emerging from the transition module 16 coaxial filter strand the in Fig. 3 is denoted by the reference numeral "24", in the illustrated embodiment, only transported along the path 14a in the single-strand machine 14.
  • the coaxial filter strand 24 is subjected to the same further processing steps, as is the case with a simple filter strand, to the further processing of the single-strand machine 14 would be used in a conventional manner.
  • the Koaxialfilterstrang 24 is wrapped in particular with a wrapping material strip and then cut into filter rods.
  • two wedge rollers 26 provided as pulleys over which the first Filter tow 6 is performed.
  • the second embodiment according to Fig. 2 are provided as deflection two nozzles and / or funnels 27, through which the first filter tow 6 is guided.
  • the wedge rollers 26 according to Fig. 1 and the nozzles or funnels 27 according to FIG Fig. 2 In addition to their deflection function, they can also support the circular shaping of the first filter tow strip 6.
  • two spaced-apart rollers 28 are rotatably mounted for the purpose of better guidance of the lower second filter tow strip 10 in the illustrated embodiment, over which the second filter tow 10 is guided.
  • these two rollers 28 also exert a supporting function, since the second filter tow strip 10 rests on it. Since the second filter tow 10 must be spread substantially flat or slightly curved, the use of rollers is required because they have a wider footprint than, for example, the aforementioned wedge grooves 26.
  • the lateral surface of the rollers 28 a little concave, whereby the second filter tow 10 is already preformed a little. This gives it a downward slight curvature transverse to its longitudinal extension, with which it then runs in the wrapping device 22, whereby the wrapping process takes place there is simplified.
  • the wrapping device 22 has an inlet or wrapping finger 30, which in Fig. 4 is shown.
  • This wrapping finger 30 is a hollow body which tapers in the conveying direction according to the arrow A and which is open at its two end faces.
