I-idler eklanywe kahle izoba nomthelela omuhle kumshini wokuhambisa ibhande
Ukuqeqesha noma ukulandelela ibhande kusitaki sakho se-radial nomauhlelo lwe-roller conveyorkuyinqubo yokulungisa ama-idlers, ama-pulleys, nezimo zokulayisha ngendlela ezolungisa noma yikuphi ukuthambekela kwebhande ukusebenza ngaphandle kwendawo emaphakathi.Umthetho oyisisekelo okumelwe ukhunjulwe lapho ulandelela ibhande lokuthutha ulula, "IBHANDE LIYA KULESO PHELO LEROLI/I-IDLER ELIXHUMANA KUQALA."
Uma zonke izingxenye zebhande zigijima engxenyeni yobude besithumeli, imbangela cishe isendleleni noma ekumisweni kwesitaki se-radial noma izakhiwo zokuthutha, ama-idler, noma ama-pulleys kuleyo ndawo.
Uma ingxenye eyodwa noma eziningi zebhande zigijima kuwo wonke amaphuzu eduzeumthumeli, imbangela ingenzeka kakhulu ebhandeni ngokwalo, ezinhlakeni, noma ekulayisheni ibhande.Lapho ibhande lilayishwa lisuka phakathi nendawo, isikhungo samandla adonsela phansi sivame ukuthola indawo ephakathi kwamavila, ngaleyo ndlela kuholele ibhande onqenqemeni lwalo olulayishwe kancane.
Lena imithetho eyisisekelo yokuxilongwa kwezinkinga zokugijima kwebhande.Inhlanganisela yalezi zinto ngezinye izikhathi ikhiqiza amacala angabonakali ngokucacile ukuthi angabangela yini, kodwa uma inani elanele lokuguquguquka kwebhande libhekwa, iphethini yokugijima izocaca futhi imbangela idalulwe.Izimo ezivamile lapho iphethini ingaveli yilezo zokugijima okungalungile, ezingase zitholakale ebhandeni elingalayishiwe elingafaki kahle, noma ibhande elilayishiwe elingawutholi umthwalo walo ubekwe phakathi nendawo ngokufanayo.
Izinto Ezithinta Ukuqeqeshwa Kwebhande Lokuthutha
Ama-Reels Pulleys nama-Snubs
Umphumela omncane wokuqondisa utholakala kumqhele wama-conveyor pulleys.Umqhele usebenza kakhulu uma kunesikhathi eside esingasekelwe sokubhinca, (cishe ububanzi bebhande eliphindwe kane) sisondela ku-pulley.Njengoba lokhu kungenzeki ohlangothini oluthwele umthumeli, ukwenza umqhele we-pulley yekhanda kungasebenzi futhi akufanelekile ukusabalalisa okungalungile kwe-lateral kwengcindezi okukhiqizayo ebhandeni.
Ama-pulleys omsila angase abe nebanga elingasekelwe lebhande elisondela kuwo futhi ukumboza umqhele kungasiza ngaphandle kwalapho esendaweni yokungezwani kwebhande eliphezulu.Inzuzo enkulu lapha ukuthi umqhele, ngokwezinga elithile, usiza ekugxiliseni ibhande njengoba lidlula ngaphansi kwendawo yokulayisha, okudingekayo ukuze kulayishwe kahle.Ama-pulleys okuthatha ngezinye izikhathi athweswa umqhele ukuze anakekele noma yikuphi ukungahambi kahle okuncane okwenzeka ekalishi elithwalayo njengoba lishintsha indawo.
Wonke ama-pulleys kufanele abe nezinga ne-axis yawo ku-90 ° endleleni ehlosiwe yebhande.Kufanele zigcinwe zinjalo futhi zingagudluki njengendlela yokuqeqesha, ngaphandle kokuthi ama-pulleys e-snub angase agudluzwe i-axis yawo lapho ezinye izindlela zokuqeqesha zinganikezi ukulungiswa okwanele.Ama-Pulley anezimbazo zawo ngaphandle kuka-90 ° endleleni yebhande azohola ibhande elibheke emaphethelweni ebhande eliqala ukuxhumana ne-pulley engalungile.Uma ama-pulleys engekho ezingeni, ibhande livame ukugijima liye ohlangothini oluphansi.Lokhu kuphambene nesitatimende esidala "somthetho wesithupha" sokuthi ibhande ligijimela ohlangothini "oluphezulu" lwe-pulley.Uma inhlanganisela yalokhu kokubili kwenzeka, lowo onethonya elinamandla uzobonakala ekusebenzeni kwebhande.
Ukuqeqesha ibhande nabavilaphayo kufezwa ngezindlela ezimbili.Ukushintsha i-eksisi engenzi lutho ngokuphathelene nendlela yebhande, ngokuvamile eyaziwa ngokuthi “amavila angqongqozayo,” kusebenza kahle lapho ibhande lonke ligijimela ohlangothini olulodwa eduze kwengxenye ethile yesitaki noma isitaki se-radial.Ibhande lingagxilwa "ngokungqongqoza" phambili (ekuhambeni kwebhande lokuhamba) ekugcineni kwe-idler lapho ibhande ligijima khona.Amavila anyakazayo ngale ndlela kufanele asakazwe ngobude obuthile besithumeli, noma isitaki se-radial, ngaphambi kwendawo yenkinga.Kuzoqashelwa ukuthi ibhande lingase lenziwe ukuthi ligijime liqonde ingxenye yamavila “ingqongqoze” enye indlela enye enye, kodwa lokhu kungaba ngenxa yokwanda kokungqubuzana phakathi kwebhande namavila.Ngenxa yalesi sizathu, bonke abavilaphayo kufanele baqale baphindwe baphindwe ngesikwele kanye nendlela yebhande, futhi kuphela ukuguqulwa okuncane kwamavila okusetshenziswe njengendlela yokuqeqesha.Uma ibhande lilungiswe ngokwedlulele ngamavila anyakazayo, kufanele libuyiselwe ngokubuyisela amavila afanayo, hhayi ngokugudluza amavila abengeziwe kwelinye icala.
Ngokusobala, ukuguquguquka okunjalo kokungenzi lutho kusebenza ngendlela eyodwa kuphela yokuhamba ngebhande.Uma ibhande lihlehliswa, i-idler eguquliwe, elungisa ohlangothini olulodwa, izoqondisa ngendlela engafanele kwenye.Ngakho-ke amabhande ahlehlayo kufanele enze wonke ama-idlers abekwe isikwele futhi ashiywe kanjalo.Noma ikuphi ukulungiswa okudingekayo kungahlinzekwa ngamavila aziqondanisayo adizayinelwe ukuhlehlisa ukusebenza.Akuwona wonke ama-self-aligners alolu hlobo, njengoba amanye asebenza ohlangothini olulodwa kuphela.
Ukutshekisela i-idler phambili (hhayi ngaphezulu kuka-2°) lapho uhamba khona ngebhande kukhiqiza umphumela wokuziqondanisa.Amavila angase atshekiswe ngale ndlela ngokucwayiza umlenze ongemuva wesitendi esingenzi lutho.Nalapha futhi, le ndlela ayigculisi lapho amabhande angase ahlehliswe khona.
Le ndlela inenzuzo ngaphezu "kokungqongqoza kwamavila" ngoba izolungisa ukuhamba kwebhande kuya nhlangothi zombili zomuntu ovilaphayo, yingakho iwusizo ekuqeqesheni amabhande angahlelekile.Inobubi bokukhuthaza ukushesha ukugqokwa kwekhava ye-pulley ngenxa yokukhuhlana okukhulayo kumaroli okudonsa amanzi.Ngakho-ke kufanele isetshenziswe kancane ngangokunokwenzeka - ikakhulukazi kuma-idlers asezingeni eliphezulu.
Amavila akhethekile, aziqondanisayo afana nalona ongakwesokudla ayatholakala ukuze asize ekuqeqesheni ibhande.
Amavila abuyayo, ayisicaba, awanikezi ithonya lokuzilinganisa njengasendabeni yamavila atshekile.Kodwa-ke, ngokushintsha i-axis yabo (ukushaya) ngokuphathelene nendlela yebhande, umqulu wokubuyisela ungasetshenziswa ukunikeza umphumela wokulungisa njalo ohlangothini olulodwa.Njengasendabeni yamaroli okugoqa, isiphetho somqulu lapho ibhande lisuka khona kufanele lihanjiswe ngobude lapho liqondiswa khona ibhande lokubuya ukuze linikeze ukulungiswa.
Imiqulu yokuziqondanisa yokubuyisela nayo kufanele isetshenziswe.Lezi zikhonjiswe mayelana nephinikhodi emaphakathi.Ukuzulazula komqulu mayelana nale phini kubangela ibhande elingekho maphakathi nendawo futhi i-eksisi ye-idler roll iyagudluka ngokuhlonishwa kwendlela yebhande esenzweni sokuzilungisa.Abanye abavilaphayo ababuyayo benziwa ngamaroli amabili akha i-10° ukuya ku-20° V-trough, esebenza ngempumelelo ekusizeni ukuqeqesha ukugijima okubuyayo.
Usizo olwengeziwe lokumisa ibhande phakathi nendawo lapho lisondela ku-pulley yomsila lingase libe khona ngokuqhubekela phambili kancane futhi liphakamise ezinye iziphetho zama-return roll eduze kwe-pulley yomsila.
Ukuqinisekisa Ukusebenza Kwemiqulu Yokuqeqesha
Imvamisa, ingcindezi eyengeziwe iyafuneka kumavila azenzelayo
futhi, kwezinye izimo, kumavila ajwayelekile lapho kudingeka khona ukuqeqeshwa okunamandla.Enye indlela yokufeza lokhu ukuphakamisa amavila anjalo ngaphezu komugqa wamavila aseduze.Ama-Idler noma ama-pulleys agobile kumajika ayi-convex (i-hump) eceleni kohlangothi lokubuya anengcindezi eyengeziwe ngenxa yezingxenye zokudonsa kwebhande ngakho-ke ayizindawo zokuqeqesha ezisebenzayo.Ama-self-aligners aseceleni athwele akumele abekwe ejikeni eliyi-convex njengoba izindawo zawo eziphakeme zingase zikhuthaze ukwehluleka kokungenzi lutho kwesidumbu.
Iziqondiso zalolu hlobo azinconywa ukuthi zisetshenziswe ekwenzeni amabhande agijime aqonde.Zingase zisetshenziselwe ukusiza ekuqeqesheni ibhande ekuqaleni ukuze livimbele ukuthi lingaphumi kuma-pulleys futhi lizilimaze ngokumelene nesakhiwo sesistimu yokuthutha.Angase futhi asetshenziselwe ukukhokhela uhlobo olufanayo lokuvikela ibhande njengesinyathelo esiphuthumayo, inqobo nje uma angathinti unqenqema lwebhande lapho lisebenza ngokujwayelekile.Uma ziqhubeka zithwala ibhande, nakuba zikhululekile ukugoqa, zivame ukuguga onqenqemeni lwebhande futhi ekugcineni zibangele ukuhlukana kwe-ply onqenqemeni.Ama-roller okuqondisa ohlangothini akufanele abekwe ukuze athwale ngokumelene nonqenqema lwebhande uma ibhande empeleni seliku-pulley.Kuleli qophelo, akukho ukucindezela komphetho ongahambisa ibhande eceleni.
Ibhande ngokwalo
Ibhande elinokuqina okweqile kwezinhlangothi, uma kuqhathaniswa nobubanzi balo, kuzoba nzima kakhulu ukuliqeqesha ngenxa yokungaxhumani kwalo neroli eliphakathi nendawo lendoda engenzi lutho.Ukuqashelwa kwaleli qiniso kwenza umsebenzisi akwazi ukuthatha izinyathelo zokuphepha ezengeziwe futhi, uma kunesidingo, alayishe ibhande ngesikhathi sokuqeqeshwa ukuze athuthukise ikhono lalo lokuqondisa.Ukubhekwa kwemikhawulo yokuklama ikhono lokudoba ngokuvamile kuzoyigwema le nkinga.
Amanye amabhande amasha angase agijimele ohlangothini olulodwa, engxenyeni ethile noma izingxenye zobude bawo, ngenxa yokusabalaliswa okungalungile kwe-lateral kwengcindezi.Ukusebenza kwebhande ngaphansi kwengcindezi kulungisa lesi simo cishe kuzo zonke izimo.Ukusetshenziswa kwamavila okuziqondanisa kuzosiza ekwenzeni ukulungisa.
