(54) Fremgangsmåde til fremstilling af cigaretmundstykkestænger, som kan opdeles 1 individuelle mundstykker.(54) Process for producing cigarette mouthpieces which can be divided into 1 individual mouthpieces.
Den foreliggende opfindelse angår en fremgangsmåde til fremstilling af cigaretmundstykkestænger, som kan opdeles i individuelle mundstykker, der har en sektion af partikelformet materiale på linie med filterpropper, som med bestemte indbyrdes mellemrum fremfødes på samme linie. Fremstillingen af sådanne cigaretmundstykkestænger kendes fx fra US patentskrifterne ^ nr. 3.482.488 og 3.524.454.The present invention relates to a method of producing cigarette mouthpieces which can be divided into individual mouthpieces having a section of particulate material aligned with filter plugs which are spaced at certain intervals along the same line. The manufacture of such cigarette mouthpieces is known, for example, from US Patents Nos. 3,482,488 and 3,524,454.
O I de ovennævnte patentskrifter angives en konstruktion ^ af en sammensat filterstang, hvori sektioner eller propper af -¾- filtermateriale af samme eller forskellig karakter er anbragt imellem en anden gruppe filterpropper placeret med en indbyrdes afstand på et vandrende indre svøb. Dette svøb har en bredde der ^ er lidt mindre end filterproppernes omkreds, og det er formet om- 145405 2 * kring størstedelen af disse filterproppers perifere udstrækning. Således afgrænses en øvre åbning mellem randsidekanterne af det indre svøb, og disse åbninger er i forbindelse med de rum af på forhånd valgt størrelse, der ligger mellem filterpropperne. De delvis indsvøbte filterpropper føres gennem et apparat til tildeling af partikelformet materiale ved hvilket rummene mellem filterpropperne fyldes med dette materiale gennem de øvre åbninger. For at forøge påfyldningshastigheden og for at sikre optimal tæthed af det partikelformede materiale, kan der sættes sugning til det første svøb under tildelingsapparatets udløbsåbning. De delvis indsvøbte filterpropper og de indskudte sektioner af partikelformet materiale passerer gennem en anden indsvøb-ningsindretning hvor et andet svøb med større bredde foldes omkring stangen, således at den øvre åbning, der er afgrænset af det indre svøb, bliver dækket. Det ydre svøbs sidekanter overlapper hinanden og er hensigtsmæssigt forseglet med hinanden. Den kontinuerlige stang opdeles derpå i stænger af den ønskede længde, hvilke stænger derpå indføres i en konventionel maskine til påsætning af filtermundstykker, hvorved der dannes cigaretter med et mundstykke der har to filterpropper af en bestemt karakter og som har en indbyrdes afstand samt en mellemliggende sektion med partikelformet materiale.In the aforementioned patents, a construction of a composite filter bar is indicated in which sections or plugs of -¾- filter material of the same or different nature are arranged between another group of filter plugs spaced apart on a traveling inner envelope. This envelope has a width which is slightly smaller than the circumference of the filter plugs, and it is formed about the majority of the peripheral extent of these filter plugs. Thus, an upper opening is delimited between the rim side edges of the inner envelope, and these openings are in connection with the preselected spaces located between the filter plugs. The partially encased filter plugs are passed through an apparatus for delivering particulate material in which the spaces between the filter plugs are filled with this material through the upper openings. In order to increase the filling rate and to ensure optimum density of the particulate material, suction can be added to the first shroud under the outlet opening of the delivery apparatus. The partially wrapped filter plugs and the inserted sections of particulate material pass through a second wrapping device where a second larger width envelope is folded around the rod so that the upper opening delimited by the inner envelope is covered. The outer edges of the outer envelope overlap and are suitably sealed with each other. The continuous bar is then divided into bars of the desired length, which bars are then inserted into a conventional filter nozzle attachment machine, thereby forming cigarettes with a nozzle having two filter plugs of a particular character and spaced apart and an intermediate section. with particulate material.
Selvom sammensatte filtre fremstillet i overensstemmelse med de ovennævnte patentskrifter har vist sig at være yderst tilfredsstillende og succesfulde, har det vist sig at når det partikelformede materiale indføres i rummet mellem filterpropperne, vil det af og til komme ind i de forholdsvis små hulrum mellem det indre svøbs randsidekanter og filterpropperne, og det kan eventuelt trænge derind selv efter påføringen af det ydre svøb. Naturligvis nedsætter det ikke blot filterets kvalitet, men indvirker under visse omstændigheder også på filtreringseffekten.Although composite filters made in accordance with the aforementioned patents have been found to be extremely satisfactory and successful, it has been found that when the particulate material is introduced into the space between the filter plugs, it will occasionally enter the relatively small voids between the inner the edge edges of the wrapper and the filter plugs, and it may penetrate even after the outer wrapper is applied. Of course, not only does it reduce the quality of the filter, but in certain circumstances also affects the filtering effect.
Det er formålet med den foreliggende opfindelse at eliminere de førstnævnte problemer ved at sikre at det partikelformede materiale holdes inden for den centrale sektion mellem filterpropperne .It is the object of the present invention to eliminate the aforementioned problems by ensuring that the particulate material is kept within the central section between the filter plugs.
Dette opnås ved anvendelse af en fremgangsmåde af den indledningsvis angivne art, hvilken fremgangsmåde er ejendommelig ved det i krav l's kendetegnende del angivne.This is achieved by using a method of the kind set out in the preamble, which is characterized by the characterizing part of claim 1.
145405 3145405 3
Den foreliggende opfindelse forklares nærmere i det følgende i forbindelse med tegningen, hvor fig. 1 er et udsnit der for oven viser en dobbelt ind-svøbningsoperation, hvor med afstand anbragte filterpropper fastgøres inden i et indre svøb til tilvejebringelse af rum med i forvejen fastsat størrelse mellem filterpropperne, til hvilke rum der er adgang ved hjælp af perforerede åbninger, hvorigennem et udvalgt partikelformet materiale kan indføres og hvilke åbninger forsegles med et ydre svøb; fig. 2 er et perspektivisk udsnit af en tilsvarende operation der viser åbningerne forseglet med hjælp af en smal strimmel; fig. 3 er et plant udsnit af et indre svøb med kun den ene sidekant perforeret eller udstandset med i forvejen fastsatte mellemrum, hvorigennem det partikelformede materiale vil kunne indføres ved dannelsen af en central partikelformet sektion; fig. 4 er et tilsvarende plant udsnit af et indre svøb med huller anbragt med mellemrum imellem sidekanterne, hvilke huller enten kan være dannet i forvejen eller er punkteret eller perforeret på stangudformningsmaskinen; fig. 5 er et udsnit svarende til fig. 1, der viser det indre svøb der punkteres mens det er på stangudformningsmaskinen og før indføringen af det partikelformede filtreringsmateriale; fig. 6 er et udsnit af en opstalt der viser dannelsen af en sammensat cigaretmundstykkestang, hvor den under fremstilling værende stang fremføres intermitterende for at lette indførelsen af det partikelformede materiale i den centrale sektion.The present invention will be explained in greater detail in the following with reference to the drawing, in which: FIG. 1 is a section above showing a double enclosure operation in which spaced filter plugs are secured within an inner envelope to provide a predetermined size between the filter plugs to which spaces are accessed by perforated openings through which a selected particulate material may be introduced and which openings are sealed with an outer envelope; FIG. 2 is a perspective view of a corresponding operation showing the openings sealed by a narrow strip; FIG. 3 is a planar section of an inner envelope with only one side edge perforated or spaced at predetermined intervals through which the particulate material may be introduced by the formation of a central particulate section; FIG. 4 is a similar planar section of an inner envelope with holes spaced between the side edges, which holes may either be formed in advance or are punctured or perforated on the rod forming machine; FIG. 5 is a section similar to FIG. 1, showing the inner envelope punctured while on the rod forming machine and prior to the introduction of the particulate filtration material; FIG. 6 is a sectional view of an upright showing the formation of a composite cigarette mouthpiece, with the bar in progress being intermittently advanced to facilitate the introduction of the particulate material into the central section.
På fig. 1 dannes en sammensat filterstang med dobbelt svøb ved først at tilvejebringe et første indre svøb 10 med en bredde der er mindst lige så stor som omkredsen af de udvalgte filter^" propper 12a og 12b som kan være af det samme eller af forskelligt materiale. I dette tilfælde er bredden af det indre svøb 10 større end omkredsen af filterpropperne 12a og 12b, idet sidekanterne af svøbet vil overlappe hinanden og sikres på passende måde til hinanden. Det til svøbet 10 valgte materiale kan være af termoplastisk natur eller kan være valgt blandt mange forskellige andre materialer, som fx plast, papir eller lignende, som vil tilvejebringe en i alt væsentligt selvunderstøttende stang for indførelsen af det partikelformede materiale i rummene mellem filterproppeme 12a og 12b. Dette vil sikre et ensartet tværsnit af stangén før 145405 4 og efter påfyldningen. Om ønsket eller nødvendigt kan de med afstand anbragte filterpropper 12a og 12b være sammensmeltet eller på anden måde passende fæstnet eller bundet til det indre svøb 10 . for at opretholde den ønskede indbyrdes afstand. Ved den på fig. 1 illustrerede fremgangsmåde er det indre svøb 10's sidekanter udskåret eller på anden måde perforeret på hensigtsmæssig måde med fastlagte mellemrum til at tilvejebringe åbninger, hvorigennem det udvalgte partikelformede materiale kan indføres i den centrale sektion 14. Således dannes der ved denne fremgangsmåde i forvejen udsnit eller perforeringer 16a og 16b, der ligger overfor hinanden og som tilsammen danner åbningen 18, som kan have en hvilken som helst passende længde, der er lige så stor eller mindre end mellemrummet mellem filterpropperne 12a og 12b.In FIG. 1, a double-wrapped composite filter bar is formed by first providing a first inner wrapper 10 having a width at least as large as the circumference of the selected filters ^ "plugs 12a and 12b, which may be of the same or of different material. in this case, the width of the inner envelope 10 is greater than the circumference of the filter plugs 12a and 12b, since the side edges of the envelope will overlap and be suitably secured to each other. The material selected for the envelope 10 may be of thermoplastic nature or may be selected from many. various other materials, such as plastic, paper or the like, which will provide a substantially self-supporting rod for the introduction of the particulate material into the spaces between the filter plugs 12a and 12b, which will ensure a uniform cross-section of the rod before and after filling. If desired or necessary, the spacers 12a and 12b spaced apart may be fused or otherwise suitably attached clay bound to the inner envelope 10. to maintain the desired spacing. In the embodiment of FIG. 1, the lateral edges of the inner shell 10 are cut or otherwise perforated appropriately at defined intervals to provide openings through which the selected particulate material may be introduced into the central section 14. Thus, in this method, pre-cuts or perforations are formed. 16a and 16b, which are opposite each other, which together form the opening 18, which can have any suitable length equal to or smaller than the space between the filter plugs 12a and 12b.
Den delvis svøbte stang med fæstnede filterpropper 12a og 12b passerer gennem et apparat til påfyldning af løst partikelformet materiale, hvilket apparat indfører det udvalgte partikelformede materiale 20 i rummet 14.The partially wrapped bar with attached filter plugs 12a and 12b passes through a loose particulate material loading apparatus, which introduces the selected particulate material 20 into the space 14.
Den delvis svøbte stang dækkes derpå af et andet svøb 22, hvis sidekanter overlapper hinanden, hvorved svøbet fuldstændig omslutter den ydre overflade af det første svøb 10 samtidig med at det lukker eller forsegler åbningerne 18. De overlappede sidekanter på det andet svøb 22 kan fæstnes ved anvendelse af en sømklister af en type der er velkendt, og i tilfælde af at der anvendes et termoplastisk ydre svøb, kan de overlappende kanter hensigtsmæssigt sammensmeltes eller på anden måde bindes til hinanden.The partially wrapped rod is then covered by a second wrapper 22, the side edges of which overlap, whereby the wrapper completely encloses the outer surface of the first wrapper 10 while closing or sealing the openings 18. The overlapped side edges of the second wrapper 22 can be secured by using a seam adhesive of a type well known in the art, and in the case of using a thermoplastic outer wrapper, the overlapping edges may conveniently be fused or otherwise bonded to one another.
Den fuldstændig .indsvøbte stang føres derpå gennem et konventionelt afskæringsapparat som skærer den dobbeltsvøbte filterstang i på forhånd fastlagte længder. Disse længder anbringes derpå i en konventionel filtermundstykke-fastgørelsesmaskine der er tilpasset til at fæstne sammensatte mundstykker på cigaretter. Disse sammensatte mundstykker vil indbefatte filterprop 12a af materiale A, den partikelformede sektion af materiale 20 og filterprop 12b af materiale B, hvor materiale B kan være det samme som eller forskelligt fra materiale A, og kan være af samme eller forskellig længde. Den partikelformede sektion kan være af forskellige længder af det materiale der er udvalgt. Det partikelformede materiale kan være granulært, pulverformet, flageformet, 145405 5 fnugagtigt eller lignende, eller en blanding deraf, og kan fx omfatte aktivt kul, aluminiumoxyd, silikdgel, passende harpikser der kan være modificeret eller suppleret med udvalgte additiver eller andre hensigtsmæssige filtrerings- eller konditionerings-materialer. ’ På fig. 2 er illustreret en fremgangsmåde, hvor åbningerne 18 i det indre svøb 10 lukkes eller forsegles af en strimmel 22a med en ringe bredde. Naturligvis kan en strimmel 22a fastgøres til overfladen af det indre svøb 10 på en hvilken som helst hensigtsmæssig måde.The fully wrapped rod is then passed through a conventional cutting apparatus which cuts the double-wrapped filter rod to predetermined lengths. These lengths are then placed in a conventional filter nozzle attachment machine adapted to attach composite nozzles to cigarettes. These composite nozzles will include filter plug 12a of material A, the particulate section of material 20 and filter plug 12b of material B, where material B may be the same or different from material A, and may be of the same or different length. The particulate section may be of different lengths of the material selected. The particulate material may be granular, powdery, flakey, fluffy or similar, or a mixture thereof, and may include, for example, activated carbon, alumina, silica gel, suitable resins which may be modified or supplemented with selected additives or other suitable filtration or conditioning materials. In FIG. 2 illustrates a method in which the openings 18 of the inner shell 10 are closed or sealed by a strip 22a of a small width. Of course, a strip 22a can be attached to the surface of the inner envelope 10 in any convenient manner.
I fig. 3 vises et indre svøb 10a, hvor der kun forekommer udskæringer 16c på den ene af sidekanteme. Det er en fordel at størrelsen og udformningen af udskæringerne kan varieres inden for visse grænser til lettelse og fremskyndelse af indføringen af det udvalgte partikelformede materiale.In FIG. 3, an inner envelope 10a is shown, with only cutouts 16c on one of the side edges. It is an advantage that the size and shape of the cuts can be varied within certain limits to facilitate and speed up the introduction of the selected particulate material.
Ved en udførelsesform for det indre svæb 10b, der er vist på fig. 4, anvendes perforeringer 16d med i forvejen fastsatte mellemrum inde mellem sidekanterne. Disse perforeringer 16d kan enten være dannet i forvejen eller kan være udstandset på stangudformningsmaskinen i et hvilket som helst punkt før indføringen af det partikelformede materiale.In one embodiment of the inner sleeve 10b shown in FIG. 4, perforations 16d are used at predetermined intervals between the side edges. These perforations 16d may either be formed in advance or may be projected onto the rod forming machine at any point prior to the introduction of the particulate material.
I denne forbindelse henvises til fig. 5, hvor en perforator 24 arbejder synkront med fremførelsen af det indre svøb 10b.Referring to FIG. 5, where a perforator 24 operates synchronously with the conveying of the inner shell 10b.
Som vist, har perforatoren 24 form af et roterende hjul med perifere tappe der strækker sig ud til siden, hvilke tappe punkterer det indre svøb 10b i de ønskede punkter mellem de med bestemte afstande anbragte filterpropper 12a og 12b før apparatet til indførelse af partikelformet materiale.As shown, the perforator 24 is in the form of a side peripheral pin rotating wheel which punctures the inner shell 10b at the desired points between the spaced filter plugs 12a and 12b before the particulate material insertion apparatus.
Idet der nu henvises til fig. 6 kan man klart se at den foreliggende opfindelse vil tilsigte en periodevis stangudformningsoperation, i modsætning til den kontinuerlige operation der er angivet i de ovenfor nævnte patentskrifter. I denne sammenhæng stoppes det indre svøb 10, der er dannet ctnkring de med afstand anbragte filterpropper 12a og 12b, og fremføres trinvis med forud fastsatte mellemrum til nøjagtig indstilling af doserende strålerør 26 ud for åbningerne 18. Derefter indføres det partikelformede materiale i rummene 14. På denne måde opnås en optimal fyldning navnlig når der arbejdes med partikelformet materiale af forholdsvis lav tæthed. For yderligere at forbedre fyldningen af det be- 145405 6 stemte materiale, kan der påføres sugning, således som det også angives i de tidligere omtalte patentskrifter.Referring now to FIG. 6, it can be clearly seen that the present invention will aim for a periodic bar design operation, in contrast to the continuous operation disclosed in the aforementioned patents. In this context, the inner envelope 10 formed around the spacer filter plugs 12a and 12b is stopped and advances incrementally at predetermined intervals to accurately adjust dosing jet tubes 26 next to the openings 18. Thereafter, the particulate material is introduced into the compartments 14. In this way, an optimal filling is achieved especially when working with relatively low density particulate material. In order to further improve the loading of the intended material, suction may be applied, as also stated in the previously mentioned patents.
Naturligvis kan både påføringen af sugning <?g tilføringen af de doserende strålerør 26 indstilles tidsmæssigt i forhold til hinanden og synkroniseres med den trinvise fremføring af den delvist dannede stang. Når de mellemliggende rum 14 er blevet fyldt med det udvalgte partikelformede materiale, deaktiveres de doserende strålerør 26 og sugningen vil, hvis en sådan anvendes, blive fjernet, mens den delvis dannede stang fjernes, således at den næste serie af rum 14 kan blive behandlet af apparatet til påfyldning af det partikelformede materiale.Of course, both the application of suction and the supply of the dosing jet tubes 26 can be timed relative to each other and synchronized with the stepwise advance of the partially formed rod. When the intermediate compartments 14 have been filled with the selected particulate material, the dosing jet tubes 26 are deactivated and the suction, if used, will be removed while the partially formed rod is removed so that the next series of compartments 14 can be treated by the apparatus for filling the particulate material.
