Uma ufuna noma yimuphi umshini osebenza kuma-reels, khona-ke udinga i-decoiler noma i-decoiler.
Ukutshala imali emishinini emikhulu kuwumsebenzi odinga ukucutshungulwa kwezinto eziningi kanye nezici. Ingabe udinga umshini ohlangabezana nezidingo zakho zamanje zokukhiqiza, noma ufuna ukutshala emandleni esizukulwane esilandelayo? Le mibuzo ivame ukubuzwa abanikazi bezitolo lapho bethenga umshini wokwenza ama-roll. Kodwa-ke, ucwaningo mayelana nama-unwinders alutholanga ukunakwa okuncane.
Uma ufuna umshini osebenza kuma-reels, ngokungangabazeki uzodinga i-decoiler (noma i-decoiler njengoba ibizwa kanjalo ngezinye izikhathi). Uma unomugqa wokwakha, wokubhoboza noma wokuhlikihla, udinga i-roll unwinder yenqubo elandelayo; ngempela ayikho enye indlela yokwenza. Ukuqinisekisa ukuthi i-decoiler yakho ihambisana nezidingo zesitolo sakho kanye nephrojekthi kubalulekile ekugcineni umshini wakho wokugaya usesimweni, ngoba ngaphandle kwezinto ezibonakalayo, umshini awukwazi ukusebenza.
Imboni ishintshe kakhulu kule minyaka engu-30 edlule, kodwa ama-decoilers abelokhu eklanyelwe ukuhlangabezana nokucaciswa kwemboni ye-roll. Eminyakeni engamashumi amathathu edlule, i-diameter yangaphandle evamile (OD) yekhoyili yensimbi yayingama-intshi angu-48. Njengoba imishini iba umuntu ngamunye futhi amaphrojekthi adinga izinketho ezihlukene, amakhoyili alungiswa ukuze abe ngu-60″ bese abe ngu-72″. Abakhiqizi namuhla ngezinye izikhathi basebenzisa ama-diameter angaphandle (OD) ngaphezu kwama-intshi angu-84. zikhona. ikhoyili. Ngakho-ke, i-unwinder kufanele ilungiswe ukuze ivumelane nokushintsha kwe-diameter yangaphandle yomqulu.
Ama-Decoilers asetshenziswa kabanzi embonini yokuphrofayili. Imishini yanamuhla yokwenza umqulu inezici namandla amaningi kunangaphambili. Isibonelo, eminyakeni engu-30 edlule imishini yokwenza ama-roll yayisebenza ngamafidi angama-50 ngomzuzu (FPM). Manje agijima ngesivinini esifinyelela ku-500 FPM. Lolu shintsho ekukhiqizweni kwemishini yokwakha i-roll luphinde lwandise ukukhiqiza kanye nesethi eyisisekelo yezinketho ze-decoiler. Akwanele ukumane ukhethe noma iyiphi i-decoiler ejwayelekile, kufanele futhi ukhethe elungile. Kunezici eziningi nezici okufanele uzicabangele ukuze uhlangabezane nezidingo zesitolo sakho.
Abakhiqizi be-Decoiler banikeza izinketho eziningi zokuthuthukisa inqubo yokuphrofayili. Ama-decoiler anamuhla aqala kumaphawundi ayi-1,000. Ngaphezu kwamaphawundi angu-60,000. Lapho ukhetha i-decoiler, cabangela izici ezilandelayo:
Kufanele futhi ucabangele ukuthi yiluphi uhlobo lwephrojekthi ozobe uyenza kanye nezinto zokwakha ozobe usebenza ngazo.
Konke kuncike ekutheni yiziphi izingxenye ohlose ukuzisebenzisa emshinini wakho wokugaya, okuhlanganisa ukuthi amakhoyili apendwe kusengaphambili, amagalani noma insimbi engagqwali. Zonke lezi zici zinquma ukuthi yiziphi izici ze-unwinder ozidingayo.
Isibonelo, ama-decoiler ajwayelekile anohlangothi olulodwa, kodwa ukuba ne-decoiler enamacala amabili kunganciphisa izikhathi zokulinda lapho uphatha izinto. Ngama-mandrel amabili, opharetha angalayisha umqulu wesibili emshinini, olungele ukucutshungulwa lapho kudingeka. Lokhu kuwusizo ikakhulukazi ezimeni lapho opharetha edinga ukushintsha ama-spool njalo.
Abakhi bavame ukungaqapheli ukuthi i-unwinder ingaba wusizo kangakanani baze babone ukuthi, kuye ngosayizi womqulu, bangenza izinguquko eziyisithupha kuya kweziyisishiyagalombili noma ngaphezulu ngosuku. Uma nje umqulu wesibili usulungile futhi ulindile emshinini, asikho isidingo sokusebenzisa i-forklift noma i-crane ukulayisha umqulu ngemva kokusetshenziswa kokuqala. Ama-uncoiler adlala indima ebalulekile endaweni eyenza ukugeleza, ikakhulukazi ekusebenzeni kwevolumu ephezulu lapho imishini ingenza izingxenye ngokushintsha kwamahora ayisishiyagalombili.
Lapho utshala imali ku-decoiler, kubalulekile ukuqonda ukusebenza kwakho kwamanje namandla. Kodwa-ke, kubalulekile futhi ukucabangela ukusetshenziswa kwesikhathi esizayo komshini kanye namaphrojekthi esikhathi esizayo angenzeka emshinini wokwenza umqulu. Zonke lezi zici kufanele zicatshangelwe ngendlela efanele futhi zingasiza ngempela ekukhetheni i-unwinder efanele.
I-bale trolley yenza kube lula ukulayisha ibhali ku-mandrel ngaphandle kokulinda i-crane noma i-forklift ukuyenza.
Ukukhetha i-mandrel emikhulu kusho ukuthi ungagijima imiqulu emincane emshinini. Ngakho, uma ukhetha 24 amayintshi. Arbor, ungagijima into encane. Uma ufuna ukuthuthukela ku-36 amayintshi. inketho, lapho-ke udinga ukutshala imali ku-decoiler enkulu. Kubalulekile ukubheka amathuba esikhathi esizayo.
Njengoba ama-rolls ayekhula futhi esinda, ukuphepha kwaphansi kwesitolo kwaba yinto ekhathazayo enkulu. Ama-Uncoiler anezingxenye ezinkulu, ezihamba ngokushesha, ngakho-ke opharetha badinga ukuqeqeshwa ekusebenzeni komshini kanye nezilungiselelo zawo ezifanele.
Namuhla, izisindo ze-roll ziyahlukahluka kusuka ku-33 kuya ku-250 kg nge-intshi yesikwele, futhi ama-unwinders ashintshiwe ukuze ahlangabezane nezidingo zamandla esivuno. Ama-spools asindayo adala ukukhathazeka okwengeziwe kokuphepha, ikakhulukazi lapho usikwa itheyiphu. Umshini ufakwe izingalo zokucindezela kanye nama-buffer roller ukuqinisekisa ukuthi ama-roll awalimalanga kuphela uma kudingeka. Umshini ungaphinda ufake amadrayivu okuphakelayo kanye nezisekelo ze-sideshift ukuze usize maphakathi nebhali kunqubo elandelayo.
Ukwandisa i-mandrel ngesandla kuba nzima kakhulu njengoba i-spool iba nzima. Njengoba izitolo zisusa opharetha ku-uncoiler ziye kwezinye izindawo zesitolo ngenxa yezizathu zokuphepha, ama-mandrel okwandisa amandla kagesi namandla okubulala ngokuvamile ayadingeka. Ama-absorber othusayo angengezwa ukuze kuncishiswe ukuzungeza ngokweqile kwe-unwinder.
Ngokuya ngenqubo nesivinini, izici ezengeziwe zokuphepha zingadingeka. Lezi zici zifaka izibambi zamaroli ezibheke ngaphandle ukuze zivikele amaroli ukuthi angawi, amasistimu okulawula isivinini sokuzungeza, namasistimu okubhuleka ahlukile njengamabhuleki apholisa amanzi olayini bokukhiqiza abasebenza ngesivinini esiphezulu. Lokhu kubaluleke kakhulu ukuqinisekisa ukuthi i-unwinder iyama lapho inqubo yokwakheka kokugeleza ima.
Uma usebenza ngezinto ezinemibala eminingi, kukhona ama-unwinders akhethekile amahlanu-mandrel, okusho ukuthi ungasebenzisa imiqulu emihlanu ehlukene emshinini ngesikhathi esisodwa. Ama-opharetha angakhiqiza amakhulu ezingxenye zombala owodwa bese eshintshela komunye umbala ngaphandle kokumosha isikhathi ngokukhipha amaroli nokuwashintsha.
Esinye isici i-roll trolley, esiza ukulayishwa kwemiqulu kuma-mandrels. Lokhu kuqinisekisa ukuthi u-opharetha akudingeki alinde i-crane noma i-forklift ukuze ilayishe.
Kubalulekile ukuthatha isikhathi sokuhlola izinketho ezihlukahlukene ezitholakalayo ze-unwinder yakho. Ngama-arbor alungisekayo ukuze kuhlaliswe ama-spools angaphakathi ahlukene kanye nosayizi abaningi be-backplate ye-spool, kunezici eziningi okufanele zicatshangelwe ukuze uthole ukulingana okulungile. Uhlu lwezicaciso zamanje nezinamandla zizokusiza ukuthi ubone izici ozidingayo.
Njenganoma yimuphi omunye umshini, umshini wokwenza ama-roll unenzuzo kuphela uma usebenza. Ukukhetha i-decoiler efanele yezidingo zesitolo sakho zamanje nezesikhathi esizayo kuzosiza i-decoiler yakho isebenze ngokuphumelelayo nangokuphepha.
