Sovitelma kuitujen, ribbonin tai filamenttien jatkokäsittelyn yhteydessäArrangement for further processing of fibers, ribbon or filaments
Keksinnön kohteena on sovitelma kuitujen, ribbonin 5 tai filamenttien jatkokäsittelyn yhteydessä, joka sovitelma käsittää päällystysyksikön pinnoitteen levittämiseksi käsiteltävänä olevan kuidun, ribbonin tai filamentin pinnalle, ainakin yhden päällystysyksikön jälkeen sovitetun UV-valai-simen kuidun, ribbonin tai filamentin pinnalla olevan pin-10 noitusaineen kovettamiseksi ja välineet suojakaasun syöttämiseksi UV-valaisimen kvartsiputkeen, jolloin käsiteltävä kuitu, ribboni tai filamentti on sovitettu kulkemaan päällystysyksikön ja UV-valaisimen kvartsiputken läpi.The invention relates to an arrangement for the further treatment of fibers, ribbon 5 or filaments, which arrangement comprises a coating unit for applying a coating to the surface of the fiber, ribbon or filament to be treated, a UV lamp applied to the surface of the fiber, ribbon or filament 10 after the at least one coating unit. and means for supplying a shielding gas to the quartz tube of the UV lamp, wherein the fiber, ribbon or filament to be treated is adapted to pass through the coating unit and the quartz tube of the UV lamp.
Tällaiset ratkaisut ovat nykyään varsin yleisiä 15 etenkin optisten kuitujen käsittelyn yhteydessä, jolloin ratkaisuja käytetään esimerkiksi kuitujen värjäämisen yhteydessä. On kuitenkin selvää, että päällystämisen tarkoituksena voi olla muukin peruste kuin värierojen aikaansaaminen. Päällystämisen tarkoituksena voi olla esimerkiksi 20 optisen kuidun uudelleen päällystäminen. Olennaista on se, että päällystysaine on sellaista, että sen kovettamiseen käytetään UV-säteilyä.Such solutions are now quite common 15, especially in connection with the treatment of optical fibers, in which case the solutions are used, for example, in connection with the dyeing of fibers. However, it is clear that the purpose of the coating may be other than to cause color differences. The purpose of the coating may be, for example, to recoat 20 optical fibers. It is essential that the coating material be such that UV radiation is used to cure it.
Esimerkkeinä aiemmin käytetyistä ratkaisuista voidaan mainita FI-patenttijulkaisussa 90381 ja US-patentti-: 25 julkaisussa 5 294 260 esitetyt ratkaisut.Examples of previously used solutions are the solutions presented in FI patent publication 90381 and US patent publication: 5 294 260.
Aiemmin tunnettujen ratkaisujen epäkohtana on ollut se, että kuitu tai vastaava on ollut suojaamattomana päällystysyksikön ja UV-valaisimen välillä. Tällöin pinnoitteeseen tarttuu pölyä ja ilmaa, joka hidastaa UV-kovetuspro-30 sessia. Edellä esitetyn seikan johdosta lopputulos, ts. pinnoitteen ja tuotteen laatu ei aina ole ollut paras mahdollinen.A disadvantage of the previously known solutions has been that the fiber or the like has been unprotected between the coating unit and the UV lamp. In this case, dust and air adhere to the coating, which slows down the UV curing process. Due to the above, the end result, i.e. the quality of the coating and the product, has not always been the best possible.
Keksinnön tarkoituksena on saada aikaan sovitelma, jonka avulla aiemmin tunnetun tekniikan epäkohdat voidaan 35 eliminoida. Tähän on päästy keksinnön mukaisen sovitelman 2 102421 avulla, joka on tunnettu siitä, että päällystysyksikön ja UV-valaisimen väliin on sovitettu avattavissa oleva suojarakenne, joka on sovitettu muodostamaan ympäristöstä tiiviisti rajoitetun kulkutien käsiteltävänä olevalle kuidul-5 le, ribbonille tai filamentille.The object of the invention is to provide an arrangement by means of which the disadvantages of the prior art can be eliminated. This is achieved by means of an arrangement 2 102421 according to the invention, characterized in that an openable protective structure is arranged between the coating unit and the UV lamp, which is adapted to form a tightly restricted path for the fiber, ribbon or filament to be treated.
Keksinnön etuna on ennen kaikkea se, että pölyn ja ilman aiheuttamat haitat saadaan eliminoitua erittäin tehokkaasti. Keksinnön mukaisen ratkaisun etuna on edelleen se, että kuidun, ribbonin tai filamentin pujotus helpottuu 10 aiempaan tekniikkaan verrattuna. Ribbonin valmistuksen yhteydessä voidaan lisäksi kuitujen tulokulmaa pienentää.The main advantage of the invention is that the disadvantages caused by dust and air can be eliminated very effectively. A further advantage of the solution according to the invention is that the threading of the fiber, ribbon or filament is facilitated compared to the prior art. In addition, the incidence angle of the fibers can be reduced during the manufacture of the ribbon.
Keksintöä ryhdytään selvittämään seuraavassa tarkemmin oheisessa piirustuksessa kuvattujen esimerkkien avulla, jolloin 15 kuvio 1 esittää periaatteellisena kuvantona keksin nön ensimmäistä sovellutusmuotoa alkutilanteessa, kuvio 2 esittää periaatteellisena kuvantona kuvion 1 mukaista sovellutusmuotoa päällystystilanteessa, kuvio 3 esittää periaatteellisena kuvantona keksin-20 nön toista sovellutusmuotoa päällystystilanteessa ja kuvio 4 esittää periaatteellisena kuvantona keksinnön kolmannen sovellutusmuodon mukaista suojarakennetta.The invention will be explained in more detail with the aid of the examples described in the accompanying drawing, in which Fig. 1 shows in principle a first embodiment of the invention in the initial situation, Fig. 2 shows in principle an embodiment according to Fig. 1, shows in principle a protective structure according to a third embodiment of the invention.

Pinnoitusaineena voidaan käyttää mitä tahansa sopivaa ainetta, esimerkiksi päällystysmateriaalia, väriainetta yms., jonka kovetus tapahtuu UV-säteilyn avulla. Esimerkkeinä voidaan mainita epoksiakrylaatti, silikoniakrylaatti 5 jne. Päällystettävä kuitu voi olla optisen kuidun sijasta myös useasta kuidusta muodostettu ribboni, joku muu yhdistetty rakenne tai tekstiilikuitu, esimerkiksi aramidikuitu.As the coating material, any suitable material can be used, for example, a coating material, a dye, etc., which is cured by means of UV radiation. Examples which may be mentioned are epoxy acrylate, silicone acrylate 5, etc. Instead of an optical fiber, the fiber to be coated can also be a ribbon formed of several fibers, another combined structure or a textile fiber, for example aramid fiber.
Edellä esitetyt seikat ja kuidun vetäminen päällys-tyslaitteiston läpi ovat alan ammattimiehelle täysin ta-10 vanomaista tekniikkaa, joten ko. seikkoja ei selvitetä tässä yhteydessä tarkemmin. Tässä yhteydessä todetaan ainoastaan yleisesti, että pinnoitteella varustettava kuitu 2 vedetään päällystysyksikön 1 läpi, johon syötetään välineiden 7 avulla myös pinnoite. Pinnoitteella varustettu kuitu 15 2 ohjataan seuraavaksi UV-valaisimen 3 kvartsiputkeen 5, jolloin lampun 4 synnyttävä UV-säteily kovettaa pinnoitteen halutulla tavalla. Kvartsiputkeen 5 syötetään välineiden 6 avulla suojakaasua, esimerkiksi typpeä, jonka tarkoituksena on suojata pinnoitetta ennen kovettumista ja mahdollistaa 20 myös kovettuminen. Pinnoitteen kovettumisen jälkeen kuitu poistuu kvartsiputkesta 5. Suojakaasu voidaan imeä imuväli-neiden 8 avulla talteen. Suojakaasu voidaan myös ohjata vapaasti ympäristöön.The above considerations and the drawing of the fiber through the coating apparatus are entirely conventional to a person skilled in the art, so that the the issues are not clarified in this context. In this connection, it is stated only in general that the fiber 2 to be coated is drawn through the coating unit 1, to which the coating is also fed by means of the means 7. The coated fiber 15 2 is then directed to the quartz tube 5 of the UV lamp 3, whereby the UV radiation generated by the lamp 4 hardens the coating in the desired manner. A means of shielding gas, for example nitrogen, is supplied to the quartz tube 5 by means of means 6, the purpose of which is to protect the coating before curing and also to allow curing. After the coating has hardened, the fiber leaves the quartz tube 5. The shielding gas can be recovered by means of suction means 8. The shielding gas can also be freely directed to the environment.
Keksinnön olennaisena seikkana on se, että päällys-; 25 tysyksikön 1 ja UV-valaisimen 3 väliin on sovitettu avatta vissa oleva suojarakenne 9. Avattavissa oleva suojarakenne 9 on sovitettu muodostamaan ympäristöstä tiiviisti rajoitetun kulkutien käsiteltävänä olevalle kuidulle 2.An essential aspect of the invention is that the coating; An openable protective structure 9 is arranged between the unit 1 and the UV lamp 3. The openable protective structure 9 is adapted to form a tightly restricted path for the fiber 2 to be treated.
Edellä esitetyllä rakenteella saadaan aikaa tiivis, 30 ympäristöstä eristetty tila päällystysyksiköltä 1 UV-valai-simelle 3, jolloin ympäristön ilma, pöly tai muut epäpuhtaudet eivät voi vaikuttaa kovettumattomaan pinnoitteeseen.The above structure provides a dense, 30 isolated space from the coating unit 1 to the UV lamp 3, whereby ambient air, dust or other impurities cannot affect the uncured coating.
Kuvioiden 1 ja 2 sovellutusmuodossa avattava suojarakenne on muodostettu kiinteästä suojaputkesta 10 ja kui-35 dun 2 liikesuunnassa suojaputken 10 suhteen siirrettävästä 4 102421 päällystysyksiköstä 1. Päällystysyksikön 1 siirrettävyys voidaan toteuttaa monella eri tavalla. Päällystysyksikkö 1 voidaan sovittaa esimerkiksi kuidun 2 liikesuuntaisesti sovitettujen johteiden 11 varaan niin, että päällystysyk-5 sikköä 1 voidaan siirtää johteiden varassa kuvioiden 1 ja 2 mukaisella tavalla. Ajatuksena on se, että nostamalla päällystysyksikkö 1 yläasentoon, joka on esitetty kuviossa 1, kuitu voidaan pujottaa yksinkertaisella toimenpiteellä päällystysyksikön läpi. Laskemalla päällystysyksikkö ala-10 asentoon, joka on esitetty kuviossa 2 suojarakenne 9 sulkee päällystysyksikön 1 ja UV-valaisimen 3 välisen alueen tiiviisti ympäristöstä, jolloin aiemmin mainitut epäkohdat eliminoituvat. Tiivistys aikaansaadaan sopivien tiivisteiden avulla.In the embodiment of Figures 1 and 2, the openable protective structure is formed by a fixed protective tube 10 and a coating unit 1 movable in the direction of movement of the fiber 2 relative to the protective tube 10. The transferability of the coating unit 1 can be realized in many different ways. The coating unit 1 can be arranged, for example, on guides 11 arranged in the direction of movement of the fiber 2, so that the coating unit 5 can be moved on the guides in the manner shown in Figs. The idea is that by raising the coating unit 1 to the upper position shown in Fig. 1, the fiber can be threaded through the coating unit by a simple operation. By lowering the coating unit to the lower position 10 shown in Fig. 2, the protective structure 9 closes the area between the coating unit 1 and the UV lamp 3 tightly from the environment, whereby the aforementioned disadvantages are eliminated. Sealing is achieved by means of suitable seals.
15 Kuviossa 3 on esitetty keksinnön toinen sovellutus- muoto. Tässä sovellutusmuodossa avattava suojarakenne 29 on muodostettu teleskooppiperiaatteella toimivasta putkiväli-neestä 21. Tässä sovellutuksessa päällystysyksikkö 1 on kiinteä ja suojarakenne voidaan avata työntämällä teles-20 kooppiperiaatteella toimivaa putkivälinettä 21 kasaan kuten kuviossa 3 on nuolen avulla osoitettu. Suojarakenne 29 voidaan sulkea vetämällä putkiväline 21 takaisin pitkänä olevaan asentoon, jolloin se sulkee päällystysyksikön 1 ja UV-valaisimen 3 välisen tilan tiiviisti ympäristöstä.Figure 3 shows another embodiment of the invention. In this embodiment, open the protective structure 29 is formed on the telescope 21. In this embodiment, the principle of the coating unit 1 is fixed and the protective structure can be opened by pushing teles-20 kooppiperiaatteella working tube means 21 together as shown in Figure 3 is shown by an arrow acting tubular intermediate medium. The protective structure 29 can be closed by pulling the tubular means 21 back to the elongated position, whereby it closes the space between the coating unit 1 and the UV lamp 3 tightly from the environment.
: 25 Kuviossa 4 on esitetty keksinnön kolmas sovellutus- muoto. Kuviossa 4 on esitetty ainoastaan avattava suojarakenne 39, joka tässä sovellutusmuodossa on avattavissa oleva putkiosa 31. Putkiosa 31 on muodostettu kahdesta puolikkaasta, jotka on liitetty yhteen putkiosan pituus-30 suunnassa olevan saranavälineen 32 avulla. Putkiosan 31 puolikkaat voidaan sovittaa myös toisistaan irrotettaviksi osiksi. Puolikkaat voidaan liittää irrotettavasti toisiinsa esimerkiksi sopivien pikalukitussalpojen avulla. Puolikkaiden ei myöskään välttämättä tarvitse olla yhtäsuuria, vaan 35 on täysin mahdollista, että putkiosa 31 muodostetaan kahdesta erisuuruisesta puolikkaasta.Figure 4 shows a third embodiment of the invention. Fig. 4 shows only an openable protective structure 39, which in this embodiment is an openable pipe part 31. The pipe part 31 is formed by two halves connected together by means of a hinge means 32 in the longitudinal direction of the pipe part. The halves of the pipe part 31 can also be arranged as detachable parts. The halves can be detachably connected to each other, for example by means of suitable quick-release latches. The halves do not necessarily have to be equal, but it is entirely possible for the pipe section 31 to be formed of two halves of different sizes.
5 1024215 102421
Kuvion 4 mukaisen sovellutusmuodon toiminnasta voidaan todeta, että ko. suojarakenne 39 voidaan sijoittaa esimerkiksi kuvion 3 sovellutusmuodon suojarakenteen 29 tilalle. Tiivistys voidaan aikaansaada sopivien tiivistei-5 den avulla.Regarding the operation of the embodiment according to Figure 4, it can be stated that the the protective structure 39 can be placed, for example, in place of the protective structure 29 of the embodiment of Fig. 3. Sealing can be achieved by means of suitable seals.
Edellä esitettyjä sovellutusesimerkkejä ei ole tarkoitettu mitenkään rajoittamaan keksintöä, vaan keksintöä voidaan muunnella patenttivaatimusten puitteissa täysin vapaasti. Näin ollen on selvää, että keksinnön mukaisen 10 sovitelman tai sen yksityiskohtien ei välttämättä tarvitse olla juuri sellaisia kuin kuvioissa on esitetty, vaan muun-laisetkin ratkaisut ovat mahdollisia. Vaikka edellä esitettyjen esimerkkien yhteydessä on korostettu optisia kuituja niin on selvää, että keksintöä ei ole mitenkään rajoitettu 15 optisten kuitujen yhteyteen. Keksintöä voidaan käyttää myös esimerkiksi ribbonien tai tekstiilikuitujen yhteydessä, kuten aiemmin on todettu.The application examples presented above are not intended to limit the invention in any way, but the invention can be modified completely freely within the scope of the claims. Thus, it is clear that the arrangement 10 according to the invention or its details do not necessarily have to be exactly as shown in the figures, but other solutions are possible. Although optical fibers have been emphasized in connection with the above examples, it is clear that the invention is in no way limited to optical fibers. The invention can also be used, for example, in connection with ribbons or textile fibers, as stated above.
