Description

92756
Menetelmå putken påån suojaamiseksi Tåmån keksinnon kohteena on menetelmå putken påån suojaamiseksi.
5 Putkien påitå on tunnettua suojata pååtytulpilla, jotka toimltuksissa tehtaalta asiakkaalle pu jotetaan påiden påålle tal tyonnetåån putken sisåån. Tulppien materiaalina kåytetåån yleenså polyeteeniå tai vaahdotettua polysty-reeniå. Tulppien tehtåvånå on pitåå putket puhtaina asen-10 nuspisteeseen asti. Tåmå on erityisen tårkeåå paineputkis-sa, jotka liitetåån herkkiin laitteisiin ja joissa on kor-keat hygieniavaatimukset.
Tunnettujen tulppien haittana on se, ettå tulpat ovat irrallisia, tehtaalla mahdollisesti vasta pitkånkin 15 tehdasvarastoinnin jålkeen asennettavia tulppia, joilla lisåksi on taipumus irrota tuulen voimasta kuljetuksessa. Tulpat ovat lisåksi kalliita, eikå niiden palautus asennus-paikalta ole kåytånnon syistå mahdollista.
Tåmån keksinnon tarkoituksena on aikaansaada mene-20 telmå, jonka avulla putket ovat helposti ja edullisesti suojattavissa. Keksinnon mukaiselle menetelmålle on siten tunnusomaista se, ettå putken pååtypintaan kiinnitetåån hitsaamalla tai muulla vastaavalla saumausmenetelmållå putken pååtyå peittåvå kalvo.
25 Keksinnon muille edullisille sovellutusmuodoiIle on tunnusomaista se, mitå jåljempånå olevissa patenttivaati-muksissa on esitetty.
Keksintoå selostetaan seuraavassa esimerkin avulla viittaamalla oheisiin piirustuksiin, joissa 30 Kuvio 1 esittåå keksinnon mukaisella menetelmållå suojakalvolla varustettua putken pååtå,
Kuvio 2 esittåå suojakalvon rainaa,
Kuvio 3 esittåå keksinnon mukaista suojakalvon muo-dostus- ja saumausmenetelmåå kåytånnosså.
35 Kuvion 1 mukaisesti on putken 6 påå 1 varustettu keksinnon mukaisesti suojakalvolla 2. Kalvo 2 on kuumasau- 92756 2 mattu putken pååtypintaan kiinni siten, ettå se voidaan repaista pois ennen putken asentamista putkilinjaan. Putken 6 paåtypinnalla tarkoitetaan tåssa yhteydesså putken påån 1 leikkauspintaa, joka on kohtisuorassa tasossa putken 5 pituusakseliin nåhden. Pååtypinnan voi muodostaa myos putken påahån muodostetun muhvin tai putkeen asennetun kappa-leen pååtypinta, kuten kuvion 3 yhteydesså esitetåån.
Induktiivisen kuumasaumauksen sijasta voidaan kåyt-tåå esim. ultraåånihitsausta. Repåisyn helpottamiseksi 10 kalvoon on muodostettu vapaa reuna 3, josta kalvo repåista-esså saadaan otetta. Sellaisen saumauksen aikaansaaminen, joka keståå hyvin varastoinnin ja kuljetuksen, mutta joka silti irtoaa kalvoon tartuttaessa ja repåiståesså kåsin, on alan ammattimiehelle tunnettu asia (vrt. esim. tiettyjen 15 maitotuotteita sisåltavien pakkauksien alumiinikansien saumaus).
Suojakalvo voidaan edullisesti muodostaa kuvion 2 mukaisesta kalvorainasta 4, johon perforoidaan putken påån muotoon suhteutettu kuvio, joka kuumasaumauksen yhteydesså 20 irrotetaan kalvorainasta. Pyoreå, putken pååhån 1 nåhden ylimitoitettu kalvo 5a voidaan sijoittaa epåkeskeisesti repåisyreunan aikaansaamiseksi, kun taas pienempi kalvo 5b on muotoiltu siten, ettå siihen jåå automaattisesti vapaa reuna 3, josta kalvo voidaan repåistå pois.
25 Suojakalvo voidaan edullisesti muodostaa laminaatti- rainasta, jossa on ainakin yksi luja, kalvon halkirepeyty-mistå ehkåisevå kerros ja ainakin yksi putkimateriaaliin saumautuva tai hitsautuva kerros. Laminaatti voi olla muo-vi/muovi-, muovi/kartonki-, muovi/paperi- tai esim. muovi-/ 30 alumiinilaminaatti, mahdollisesti kuitulujitettuna. Oleel-i‘ lista on se, ettå suojakalvo saadaan niin vahvaksi, ettå se poistuu putken pååtypinnasta yhtenå kappaleena sitå poisre-påiståesså. Suojakalvon ulkopintaan voidaan edullisesti painaa kåytto- ym. ohjeita, jotka helpottavat putkien asen-35 nusta. Lisåksi suojakalvon pohjavåri on haluttaessa helpos-ti vårjåttåvisså esim. putken kåyttotarkoituksen, nimel- 3 92756 lishalkaisijan tai paineluokan mukaan.
Mahdollisimman varman suojavaikutuksen aikaansaami-seksi on edullista, jos putken pååtyå peittåvå kalvo sauma-taan putken pååtypintaan kiinni ennen kun putki poistuu 5 valmistuslinjaltaan.
Seuraavassa esitetåån kuvioon 3 viitaten esimerkki keksinndn mukaisen putken påån suojausmenetelmån kaytånnon toteutuksesta.
Leveydeltåån suojattavan putken 6 halkaisijaan suh-10 teutettu laminoitu kalvoraina 7 vedetåån kalvorullalta 8 kiristystelojen 9 ja 10 avulla. Kuviossa 3 esitetåån esi-merkin vuoksi, ettå keksinnon mukaista menetelmåå voidaan soveltaa myos putkeen 6 esiasennetun osan tai muhvin 14 jpååtypintaan, putken oman pååtypinnan sijasta. Kalvorainaan 15 7 perforoidaan tyokalun 11 avulla halutun kokoiset ja muo- toiset suojakalvot putken påitå vårten (vrt. kuvio 2). Perforoinnin jalkeen raina siirtyy eteenpain ja perforoitu kohta kohdistetaan putken pååhån. Lampolevy 12 ja/tai putki 6 liikkuvat toisiaan kohti ja puristuvat vastakkain, jol-20 loin niiden vålisså oleva kalvolaminaatti 7 hitsautuu putken pååtypintaan låmmdn ja puristuspaineen ansiosta. Sul-jenta vie aikaa tyypillisesti 1-2 s. Samanaikaisesti irro-tusrengas 13 irrottaa perforoidan kohdan kalvolaminaatista. Jåteraina kelataan jåterullalle 15 ja viedåån aikanaan 25 jåtekiertoon.
Putkista suljetaan yleenså molemmat pååt. Tåmå voidaan luonnollisesti tehdå putken kummassakin pååsså olevil-la laitteilla. Vaihtoehtoisesti kåytetåån yhtå saumauslai-tetta, jolloin putki kåånnetåån 180°. Tålldin voidaan jår-30 jeståå perforointilaite tekemåan erihalkaisijaisille putken ..i påille omat suojakalvonsa.
Alan ammattimiehelle on selvåå, ettå keksinnon eri suoritusmuodot eivåt rajoitu yllå esitettyihin esimerkkei-hin, vaan ettå ne voivat vaihdella jåljempånå olevien pa-35 tenttivaatimusten puitteissa.
