Suomi-Finland(FI) (7*0 Ruska & Co (5*0 Menetelmä ja laite rainamateriaalin päällystämiseksi sively- telan avulla - Förfarande och anordning för beklädning av bandmaterial med hjälp av en bestrykningsvals Tämä keksintö koskee menetelmää rainamateriaalin päällystämiseksi nestemäisellä tai tahnamaisella aineella, erityisesti liuotinpohjai-sella päällysteellä siten, että sovitetaan kaavainterä pyörivää sivelytelaa vasten ja johdetaan rainamateriaali sivelytelan ohi siten, että rainamateriaali koskettaa sivelytelaa, ja johdetaan päällyste-ainetta kaavainterän yläpuolelle, sivelytelan vaipan ja kaavainterän muodostamaan kouruun, jolloin sivelytelan pyörimissuunta on sellainen, että sivelytelan pinta liikkuu sivelytelan ja kaavainterän yhtymäkohdassa alaspäin. Keksintö koskee myös laitetta menetelmän soveltamiseksi, jossa laitteessa on sivelytela ja telaa vasten sovitettu kaavainterä, ja laitteisto päällysteaineen johtamiseksi kaavainterän päälle sivelytelan vaipan ja kaavainterän muodostamaan kouruun.The present invention relates to a method and apparatus for coating a web material with a liquid, paste material or a paste. in particular with a solvent-based coating by fitting the stencil blade against the rotating brush roll and passing the web material past the brush roll so that the web material contacts the brush roll, and guiding the coating material The invention also relates to an apparatus for applying the method, the apparatus comprising a brush roll and a stencil blade arranged against the roll, and an apparatus for guiding the coating material over the stencil blade formed by the coating roll casing and the stencil blade. n gutter.
Kalvojen ja papereitten silikonointia varten on olemassa monia tunnettuja menetelmiä ja laitteita. Tunnetaan ns. sauvapäällystys, jossa päällystystela pyörii päällystysainealtaaseen osittain upotettuna ja päällystettävä raina johdetaan päällystystelan ja sen yläpuolelle sovitetun kumisen vastatelan välitse päällysteen siirtyessä 2 63275 päällystystelalta rainan alapintaan. Jotta päällystysaine nousisi sopivan ohuena kerroksena päällystystelan mukana, sen viskositeetin on oltava suhteellisen pieni, mistä johtuen sen kuiva-ainepitoisuus voi olla ainoastaan 3 - 8 ί. Voidaan käyttää myös rasteroitua päällystystelaa. Ylimäärä päällystysainetta voidaan poistaa päällystystelalta käyttämällä telaa vasten sovitettua kaavainterää eli raakkelia.There are many known methods and devices for silicone films and papers. Known as the so-called. a rod coating in which the coating roll rotates partially immersed in the coating medium pool and the web to be coated is passed between the coating roll and a rubber counter roll arranged above it as the coating moves from the coating roll to the lower surface of the web. In order for the coating material to rise in a suitably thin layer with the coating roll, its viscosity must be relatively low, so that its dry matter content can only be 3 to 8 ί. A rasterized coating roll can also be used. Excess coating material can be removed from the coating roll by using a stencil blade fitted to the roll, i.e. a squeegee.
Tunnetaan myös ns. vastatelapäällystys, jossa ylimääräinen päällystys-aine pyyhitään päällystystelalta sen rinnalle sovitetun, samaan suuntaan pyörivän vastatelan avulla. Ns. *J-tela- ja 3-telapäällystysmene- e telmissä teloja voidaan sovitaa useampia rinnakkain ja/tai päällekkäin.Also known as. a counter-roll coating in which the excess coating material is wiped off the coating roll by means of a counter-roll rotating in parallel with it. In the so-called * J-roll and 3-roll coating methods, several rolls can be arranged in parallel and / or on top of each other.
Ilmaharjapäällystyksessä ylimääräinen päällystysaine poistetaan rainan pinnalta ilmapuhallusta käyttäen.In airbrush coating, excess coating material is removed from the surface of the web using air blowing.
Kaikissa edellä selostetuissa menetelmissä rainamateriaali kulkee sivelytelan yläpuolelta telaa koskettaen ja päällystysaine siirtyy rainan alapinnalle. Aineen siirto tapahtuu sivelytelalla alhaalta ylöspäin, jolloin aineen tulee olla helposti juoksevaa.In all of the methods described above, the web material passes above the brush roll in contact with the roll and the coating material is transferred to the lower surface of the web. The transfer of the substance takes place with a brush roller from the bottom up, in which case the substance must be easily flowable.
Jotta päällystysainekerros saataisiin riittävän ohueksi, on käytettävä erittäin suuria liuotinainemääriä, jopa 95 - 97 % sivelypastan määrästä. Valmistusprosessin aikana liuotinaine on haihdutettava. Koska nimenomaan silikonoinnin yhteydessä liuottimena käytetään myrkyllisiä aromaattisia hiilivetyjä, kuten tolueenia, metylketonia, benseeniä, heksaania jne., aiheuttavat runsaat liuotinhöyrymäärät riskejä sekä paloturvallisuudessa että työterveydellisellä puolella. Lisäksi suuret määrät liuottimia vaativat suuren kuivatusenergian tarpeen, . koska kuivatusilma ei saa sisältää liuottimia lähellekään räjähtäviä määriä. Kuuma kuivatusilma ventilloidaan ulos ja sen 'tilalle on otettava tehdassaliin lämmitettyä korvausilmaa.In order to make the coating layer sufficiently thin, very large amounts of solvent must be used, up to 95-97% of the amount of coating paste. During the manufacturing process, the solvent must be evaporated. Because toxic aromatic hydrocarbons, such as toluene, methyl ketone, benzene, hexane, etc., are used as solvents in connection with siliconization in particular, abundant amounts of solvent vapors pose risks both in terms of fire safety and occupational health. In addition, large amounts of solvents require high drying energy requirements,. as the drying air must not contain any explosive amounts of solvents. The hot drying air is vented out and replaced by factory-heated replacement air.
Uusimmassa, nk. kuivasilikonointimenetelmässä liuotinaineitten määriä on voitu oleellisesti laskea. Sen haittana on kuitenkin erilaisten katalyyttien synnyttämä vety, joka ilmastointihäiriöitten yhteydessä aiheuttaa räjähdysvaaran.In the latest, so-called dry siliconization method, the amounts of solvents have been substantially reduced. However, its disadvantage is the hydrogen generated by the various catalysts, which poses an explosion hazard in the event of air conditioning disturbances.
3 63275 Tämän keksinnön mukaiselle menetelmälle on tunnusomaista,se että rainamateriaali johdetaan sivelytelaa vasten sivelytelan ja kaavainterän muodostaman kourun ulkopuolella, jolloin päällysteaine siirtyy sinänsä tunnetulla tavalla sivelytelalta rainamateriaalin sivelytelaa vasten kulkevaan pintaan.The method according to the present invention is characterized in that the web material is guided against the brush roll outside the trough formed by the brush roll and the stencil blade, whereby the coating material moves from the brush roll to the surface of the web material against the brush roll in a manner known per se.
Keksinnön mukaiselle laitteelle on tunnusomaista se,... että siinä on laitteisto rainamateriaalin johtamiseksi sivelytelaa vasten sivelytelan ja kaavainterän muodostaman kourun ulkopuolella.The device according to the invention is characterized in that it has an apparatus for guiding the web material against the brush roll outside the trough formed by the brush roll and the stencil blade.
Menetelmää voidaan käyttää erilaisten muovi- ja paperikalvojen pinnoitukseen ja käsittelyyn. Laite soveltuu erityisesti paperin ja kalvon silikonointiin, mutta sillä voidaan sivellä myös muita samankaltaisia nestemäisiä, liuotinpintaisia päällysteitä, kuten esim. PVCrtä, kuumasaumaus- ja pinnoite lakkoja jne. Keksinnön mukaisessa menetelmässä siveltävän pastan liuotinainemäärää voidaan oleellisesti alentaa, jopa 50 &:iin asti. Lisäksi menetelmä ei vaadi liuottimeksi metylketonia tai tolueenia, vaan liuotinaineeksi riittää esim. vähemmän myrkyllinen heksaani.The method can be used for coating and treating various plastic and paper films. The device is particularly suitable for silicone paper and film, but can also be applied to other similar liquid, solvent-coated coatings, such as PVC, heat sealing and coating varnishes, etc. In the method according to the invention, the solvent content of the paste can be substantially reduced. In addition, the process does not require methyl ketone or toluene as a solvent, but less toxic hexane, for example, is sufficient as the solvent.
Pienet liuotinainemäärät vähentävät kuivatusenergian määrää, halventavat päällysteen hintaa eikä laitteisto välttämättä tarvitse liuotin-höyryjen talteenotto- ja polttolaitteistöa.Small amounts of solvent reduce the amount of drying energy, lower the cost of the coating, and the equipment does not necessarily require solvent vapor recovery and combustion equipment.
Huolimatta päällysteen suuresta kuiva-ainepitoisuudesta laitteella päästään erittäin alhaisiin päällystemääriin päällystettävää kalvo- 2 neliötä kohti. Laitteiston koeajoissa on>päästy jopa 0,2 g/m päällyste-määriin .Despite the high dry matter content of the coating, the device achieves very low amounts of coating per square meter of film to be coated. Up to 0.2 g / m of coating has been reached during the test runs of the equipment.
Koska keksinnön mukainen laitteisto on rakenteeltaan yksinkertainen, ovat sen hankintahinta ja käyttökustannukset edullisemmat muihin menetelmiin verrattuna.Due to the simple structure of the apparatus according to the invention, its acquisition price and operating costs are more advantageous compared to other methods.
Keksintöä selostetaan lähemmin seuraavassa viitaten oheiseen piirustukseen, joka esittää kaaviollisesti keksinnön mukaista laitetta sivulta nähtynä.The invention will be described in more detail below with reference to the accompanying drawing, which schematically shows a device according to the invention seen from the side.
Laitteistossa on pyörivä kovakromattu sivelytela jonka pinta on erikoiskäsitelty, esim. hiekkapuhallettu, rasteroitu tai kipinätyöstetty n ; 63275 ja jonka nopeutta rainamateriaalin 10 nopeuden suhteen voidaan portaattomasti säätää. Telalla on 3uhdeaäädetty käyttö eLL sen nopeus radan nopeuteen nähden pysyy esiasetellussa suhteessa.The apparatus has a rotating hard chrome-plated brush roller whose surface is specially treated, e.g. sandblasted, rasterized or spark-machined n; 63275 and whose speed with respect to the speed of the web material 10 can be infinitely adjusted. The roller has a ratio-adjusted operation eLL its speed in relation to the track speed remains in a preset ratio.
Telaa 4 vasten on sovitettu oskilloiva kaavainterä 2, joka on asetettu viistoon asentoon siten, että sen telasta poispäin oleva reuna on ylempänä kuin telaa vasten oleva reuna. Näin telan ja terän väliin jää kouru, joka muodostaa sivelypasta-altaan 11. Raavain koostuu rungosta 1, terästä 2 ja terän kiinnittimestä 3. Kaavaimen terän kuormitusta sivelytelaa vasten voidaan säätää portaattomasti vipuvarteen 5 kohdistuvalla kuormituksella F.An oscillating stencil blade 2 is arranged against the roll 4, which is placed in an oblique position so that its edge away from the roll is higher than the edge against the roll. Thus, a trough remains between the roller and the blade, which forms a brush paste 11. The reaper consists of a body 1, a blade 2 and a blade holder 3. The load of the stencil blade against the brush roll can be infinitely adjusted by the load F on the lever arm 5.
✓✓
Pasta-altaan 11 yläpuolella on pastan syöttösäiliö 7, josta pastaa syötetään telan 4 ja terän 2 väliseen kouruun terän 2 yläpinnalle. Sivelypastan kierrätyslaitteiston avulla pasta johdetaan pumppaamalla tai muulla tavalla terän 2 päälle. Tältä ylimäärä pastaa valuu yli-juoksuna kaavinlaitteiston molemmista päistä takaisin pumppualtaalle (ei esitetty kuvassa).Above the pasta basin 11 there is a pasta supply tank 7, from which the pasta is fed into a trough between the roll 4 and the blade 2 on the upper surface of the blade 2. With the help of the rolling paste recycling equipment, the paste is led by pumping or otherwise onto the blade 2. From this, the excess paste flows overflow from both ends of the scraper system back into the pump basin (not shown in the figure).
Laitteistossa on lisäksi kaksi portaattomasti säädettävää ohjaustelaa 8 ja 9, joiden avulla säädetään pinnoitettavan radan 10 kosketuskulmaa ja kosketusaikaa sivelytelaa vasten. Kuvassa on katkoviivoin esitetty telojen 8 ja 9 sekä rainan 10 toinen asento, jossa kosketuskulma on pienempi .The apparatus further comprises two steplessly adjustable guide rollers 8 and 9, by means of which the contact angle and the contact time of the track 10 to be coated are adjusted against the brush roll. The figure shows, in broken lines, the second position of the rollers 8 and 9 and the web 10, in which the contact angle is smaller.
Laitteistoa käytettäessä sivelytela 4 pyörii kuvassa nuolella A osoitettuun suuntaan siten, että telan ja kaavainterän 2 yhtymäkohdassa telan pinta liikkuu alaspäin vieden päällystysainetta kourusta 11 telan 4 ja kaavainterän 2 välisen raon kautta kaavainterän 2 alapuolelle. Päällystettävä rainamateriaali 10 johdetaan sivelytelan 4 alitse nuolien B osoittamassa suunnassa ja päällystysaine siirtyy rainamateriaalil-le sen hangatessa telaa vasten. Rainamateriaalin liikesuunta on telan kosketuskohdassa telan pinnan suuntainen ja sopivimmin jonkin verran suurempi kuin telan pintanopeus. Aineen siirtymisessä annostelutelalle 4 käytetään hyväksi painovoimaa ja päällystekerroksen pinnan tasaisuus saavutetaan rainan kulkiessa hankaavasti sivelytelan alitse. Rainamateriaalin ohjaus tapahtuu ohjaustelojen 8 ja 9 avulla, käyttämättä sivelytelaa vasten olevaa vastatelaa.When using the apparatus, the brush roll 4 rotates in the direction indicated by the arrow A in the figure so that at the junction of the roll and the stencil blade 2 the roll surface moves downwards, taking coating material from the trough 11 through the gap between the roll 4 and the stencil blade 2 below the stencil blade 2. The web material 10 to be coated is guided under the brush roll 4 in the direction indicated by the arrows B, and the coating material is transferred to the web material as it rubs against the roll. The direction of movement of the web material at the point of contact of the roll is parallel to the surface of the roll and preferably somewhat higher than the surface speed of the roll. Gravity is used in the transfer of the substance to the dosing roll 4 and the uniformity of the surface of the coating layer is achieved as the web travels abrasively under the coating roll. The web material is guided by means of guide rollers 8 and 9, without using a counter roll against the brush roller.

Sivelytelan 4 ja rainan 10 ratanopeuksia voidaan molempia säätää. Muuttamalla nopeuksien suhdetta voidaan säätää silikonipäällysteen määrää pinta-alayksikköä kohti. Päällysteen määrää voidaan lisäksi säätää muuttamalla ohjaustelojen 8 ja 9 avulla päällystettävän kalvon kosketuspintaa sivelytelaa vasten tai muuttamalla kaavaimen teräpainetta. Myös sivelytelan pintakäsittelyn laatu vaikuttaa päällystekerroksen paksuuteen.The web speeds of the winding roller 4 and the web 10 can both be adjusted. By changing the speed ratio, the amount of silicone coating per unit area can be adjusted. In addition, the amount of coating can be adjusted by changing the contact surface of the film to be coated against the coating roller by means of the guide rollers 8 and 9 or by changing the blade pressure of the stencil. The quality of the surface treatment of the brush roll also affects the thickness of the coating layer.
Keksintö ei rajoitu vain edellä esitettyyn sovellutukseen vaan se voi vaihdella'huomattavastikin patenttivaatimusten puitteissa.The invention is not limited only to the application described above, but may vary considerably within the scope of the claims.
Menetelmää voidaan käyttää kaikenlaisten rainojen päällystykseen erilaisilla nestemäisillä tai tahnamaisilla päällysteaineilla.The method can be used to coat all types of webs with various liquid or paste-like coatings.
