Sileän muoviputken valmistuslinja Tämä keksintö koskee sileän muoviputken valmistus-linjaa, joka muodostuu korrugoitua tai ripalaippaputkea 5 valmistavasta tuotantolinjasta.The present invention relates to a smooth plastic pipe production line consisting of a production line producing corrugated or ribbed flange pipe 5.

Seuraavassa käytetään yhteistä nimitystä korrugoitu putki ko. putkityypeille. Esim. FI-patentista 60825, EP-hakemusjulkaisusta EP 208055 ja DE-hakemusjulkaisuista 3622775 ja 3632225 tunnetaan korrugoitujen putkien valmis-10 tuslinjoja, joissa plastiseen tilaan saatettu muovimassa puristetaan suuttimen avulla toisiaan vastaan puristettujen liikkuvien muottipuoliskojen väliin jatkuvan laipparaken-teen aikaansaamiseksi putken ulkopinnalle.In the following, the common name is used for the corrugated pipe. types of pipes. For example, FI patent 60825, EP application EP 208055 and DE application publications 3622775 and 3632225 disclose production lines for corrugated pipes in which a plastic mass placed in a plastic state is pressed by a nozzle between movable mold halves pressed against each other to form a continuous flange.

Tällainen valmistuslinja on liikkuvien muottien 15 hallintayksiköineen, jota vastedes kutsutaan korrugaatto- riksi, hyvin raskas ja joustamaton, tarkasti asennettava ja useimmiten korrugoitujen putkien kysyntään nähden turhankin suuritehoinen, josta syystä valmistuslinja seisoo suuremman osan ajasta.Such a production line with its control units for moving molds 15, hereinafter referred to as corrugator, is very heavy and inflexible, precisely installed and, in most cases, unnecessarily high for the demand for corrugated pipes, which is why the production line stands up most of the time.

20 Nyt esiteltävä keksintö perustuu ylläolevan ongelman tiedostamiseen, sekä toisaalta siihen oivallukseen, että korrugoitujen putkien linjassa on korrugaattoria lukuun ottamatta samat.tuotantokoneet ja -elimet kuin sileäput-kilinjässäkin, toisaalta siihen oivallukseen, että eräät 25 korrugaattorimallit ovat sellaisia, että muottipuoliskoja liikuttavat ylä-ja alapuoliset radat ovat ajettavissa erilleen kokillien vaihtoa ja huolto- ym. töitä varten. Keksinnön mukaiselle parannetulle muoviputken valmistuslinjalle on siten tunnusomaista se, että valmistettavien put-30 kien muodostuselimeen eli korrugaattoriin on sovitettu kor-rugaattorin muottiratojen väliin sinänsä tunnettu sileäput-ken muodostuselin eli kalibrointiallas jonka toiseen päähän korrugaattoria normaalisti syöttävä extruuderi syöttää sulaa rauoviputkiaihiota, ja jonka toisesta päästä tuleva 35 olennaisesti sileä muoviputki käsitellään korrugoidun tai 2 83187 ripalaippaputken jälkikäsittelylaitteilla.The present invention is based on the awareness of the above problem, on the one hand, on the realization that the corrugated pipe line has the same production machines and means as the smooth tube line, except for the corrugator, and on the other hand, that some corrugator designs are such that the mold halves are the tracks below can be run apart for mold change and maintenance and other work. The improved plastic pipe production line according to the invention is thus characterized in that a smooth pipe forming member, i.e. a calibration basin known per se, 35 substantially smooth plastic tubes are treated with post-processing equipment for corrugated or 2 83187 fin flange tubes.

Keksinnön merkittävin etu on se, että kallista valmistuslinjaa ei tarvitse seisottaa, vaan että korrugaat-toria siirtämättä ja asennusta purkamatta voidaan ajaa 5 tavallista muoviputkea, kunnes korrugoiduista putkista on taas kysyntää. Tällöin yksinkertaisesti poistetaan kalib-rointiallas, mahdollisesti asenneteaan tai vaihdetaan kyseeseen tulevan korrugoidun putken kokillit, ajetaan ko-killit yhteen ja käynnistetään normaali korrugoitujen put-10 kien tuotanto.The most significant advantage of the invention is that the expensive production line does not have to be stopped, but that 5 ordinary plastic pipes can be run without relocating the corrugator and disassembling, until there is again a demand for corrugated pipes. In this case, simply remove the calibration basin, possibly install or replace the molds of the corrugated pipe in question, run the molds together and start the normal production of the corrugated pipes.

Keksintöä selostetaan seuraavassa esimerkin avulla viittaamalla oheisiin piirustuksiin, joissa kuvio 1 esittää tavanomaista ripalaippaputken tuo-tantolinjaa 15 kuvio 2 esittää keksinnön mukaisesti korrugaattoriin sijoitettua sileän putken kalibrointiallasta.The invention will now be described, by way of example, with reference to the accompanying drawings, in which Figure 1 shows a conventional rib flange tube production line. Figure 2 shows a smooth tube calibration basin placed in a corrugator according to the invention.

Kuvion 1 mukaisessa ripalaippaputken tuotantolinjassa extruuderi on merkitty viitenumerolla 1, extruuderin suutin numerolla 2, korrugaattori numerolla 3, putken jääh-20 dytysaltaat numerolla 4, putken vetolaite numerolla 5, sahalaite numerolla 6 ja määrämittaansa sahatun putkituot-teen viimeistely- ja käsittelylaitteisto numerolla 7. Suoraseinäisen putken valmistuslinjalta se poikkeaa olennaisesti vain korrugaattorin 3 osalta. Kuvassa korrugaatto-25 ri on sitä tyyppiä, jossa on kaksi muottikappaleiden eli kokillien kiertorataa, jotka voidaan ajaa erilleen toisistaan kuviossa näkyvien pystysuuntaisten siirtoelimien A avulla, jotka ovat esim. kierretankoja. Käytössä on myös korrugaattoreita, joissa kokilliradat ovat vaakatasossa 30 ja/tai kokillien paluuliike on järjestetty tapahtuvaksi erillistä rataa pitkin. Muutoin tällaisen tuotantolinjan eri laitteiden merkitys ja toiminta on alan ammattimiehelle selvä asia, joten sitä ei selitetä tässä tarkemmin.In the rib flange pipe production line according to Fig. 1, the extruder is denoted by reference number 1, extruder nozzle by number 2, corrugator by number 3, pipe cooling basins by number 4, pipe puller by number 5, saw device by number 6 and sawn pipe finishing and processing equipment number 7. it differs substantially from the pipe production line only in respect of the corrugator 3. In the figure, the corrugator-25 ri is of the type having two orbits of moldings, i.e. molds, which can be driven apart by means of the vertical transfer members A shown in the figure, which are e.g. threaded rods. There are also corrugators in which the mold tracks are horizontal 30 and / or the return movement of the molds is arranged to take place along a separate track. Otherwise, the significance and operation of the various devices on such a production line will be obvious to a person skilled in the art, so it will not be explained in more detail here.

Kuviossa 2 esitetään keksinnön mukaisesti korrugaat-35 torin erilleen ajettujen kokillimuottien 9,10 väliin sijoi- 3 83187 tettua kalibrointiallasta 8. Ekstruuderin suuttimesta tuleva putkiaihio 11 syötetään nuolen mukaisesti kalibroin-tiältään toisessa päässä olevan messinkisen kalibrointihol-kin 13 kautta jäähdytystilaan, jossa vallitsee alipaine, 5 joka imee putken tiiviisti kalibrointiholkin sisäseinämää vasten, antaen putkelle kiiltävän tasaisen pinnan. Putkea jäähdytetään pitkin kalibrointiallasta vesisuihkujen 14 avulla tunnetun tekniikan mukaisesti, jonka jälkeen se poistuu kalibrointialtaasta vetolaitteen 5 (kuvio 1) vetä-10 mänä määrämittoihinsa sovitettuna ja jäähdytettynä putkena 12. Jäähdytystä ja tuotantonopeutta voidaan tehostaa käyttämällä useampaa jäähdytysallasta 4.Figure 2 shows, in accordance with the invention korrugaat-35 rotor driven apart die forms disposed between the 9,10 83 187 3 8 tettua kalibrointiallasta from the extruder nozzle tube blank 11 is fed as shown by arrow calibration-tiältään the other end of the brass-kalibrointihol each 13 through a cooling mode in which negative pressure prevails, 5 which sucks the tube tightly against the inner wall of the calibration sleeve, giving the tube a shiny flat surface. The tube is cooled along the calibration basin by means of water jets 14 according to the prior art, after which it exits the calibration basin as a pull-10 tube of the traction device 5 (Fig. 1) fitted and cooled to its specified dimensions 12. Cooling and production rate can be enhanced by using several cooling basins 4.

Kalibrointiallas 8 voidaan kiinnittää sarjaan kytketyistä kokilleista 16 muodostettujen kokillimuottien 9,10 15 väliin esim. kiinnittämällä se kokillirakenteeseen tuki-tangoin, tai asettamalla se välikappaleiden 15 varassa lepäämään kokilleja 16 vasten, kuten kuviossa 2 on esitetty. Kuvion 2 mukainen järjestely voidaan käyttää myös silloin, kun kalibrointiallas keksinnön erään sovellutusmuo-20 don mukaisesti muodostuu osasta ripalaippaputken jäähdy-tysaltaasta 4, (vrt. kuvio 1), joka on esim. teleskooppi-maisesti työnnetty korrugaattorin avattujen kokillien väliin, kuten kuvion 2 katkoviivoitus osoittaa.The calibration basin 8 can be fastened between the molds 9,10 15 formed of the molds 16 connected in series, e.g. by attaching it to the mold structure with support rods, or by placing it on the spacers 15 to rest against the molds 16, as shown in Fig. 2. The arrangement according to Fig. 2 can also be used when, according to an embodiment of the invention, the calibration basin consists of a part of the fin flange tube cooling basin 4, (cf. Fig. 1) which is e.g. telescopically inserted between the corrugator's opened molds, such as the broken line in Fig. 2 point.

Riippuen korrugaattorin rakenteesta ja valmistetta-25 vien putkien kokoalueesta voidaan myös menetellä niin, että kokillit poistetaan ja kalibrointiallas 8 sijoitetaan kokillimuottien kuljetusradan 17,18 väliin.Depending on the structure of the corrugator and the size range of the tubes to be prepared, it is also possible to remove the molds and place the calibration basin 8 between the transport paths 17,18 of the molds.

Alan ammattimiehelle on selvää, että keksintö ei rajoitu yllä esitettyihin esimerkkeihin, vaan että keksin-30 nön eri sovellutusmuodot voivat vaihdella jäljempänä olevien patenttivaatimusten puitteissa. Alipainekalibrointial-tanna tilalla voidaan yhtä hyvin käyttää painekalibrointi-laitteistoa, jossa rakenteellisena erona on putkiaihion sisällä oleva tulppa, joka mahdollistaa ylipaineen ylläpi-35 tämisen aihioputken sisäpuolella. Kokilleja voidaan myös 4 83137 käyttää kalibrointialtaan rakenneosana. Tällöin allas muodostuu suljetusta kokilliketjusta ja sen alku- ja loppupää-hän sijoitetuista päätyelementeistä.It will be clear to a person skilled in the art that the invention is not limited to the examples given above, but that different embodiments of the invention may vary within the scope of the claims below. In the case of a vacuum calibration al-Tanna, a pressure calibration apparatus can equally well be used, in which the structural difference is a plug inside the pipe blank, which makes it possible to maintain an overpressure inside the blank tube. The molds can also be used as a component of the 4 83137 calibration basin. In this case, the pool consists of a closed mold chain and end elements located at its beginning and end.
