Mau Oyamba: Pepalali lagawidwa magawo awiri: Gawo loyamba limafotokoza za kuyambika ndi mfundo ya makina owongolera oyeserera a multihead weigher. Gawo lachiwiri makamaka limayambitsa kusanthula ndi njira zothetsera mavuto omwe amapezeka a multihead weigher mwatsatanetsatane. Kuyambitsa ndi mfundo ya multihead weigher automatic control system.

Multihead weigher (Chingerezi Loss-in-weight) ndi choyezera mitu yambiri yomwe idagwiritsidwa ntchito popanga mafakitale m'ma 1990s. Ndi kukweza kwatsopano kwa njira zotsimikizira za metrological, choyezera chambiri chimagwiritsidwa ntchito pang'onopang'ono potsimikizira zotsimikizira za metrological. Ndi chitukuko chofulumira cha makina owongolera zida zamagetsi, makina atsopano owongolera makompyuta adasankhidwa malinga ndi mawonekedwe a weigher yamitundu yambiri, ndipo kutsimikizika kwa metrological kutha kuonjezedwa mpaka 0.1% ~ 0.2%.

Chifukwa cha kusankha kosalekeza kutsimikizira muyeso wa dziko lopanda kulemera, kungatsimikizire kuti zinthuzo zimasakanizidwa molingana, ndipo kufunikira kwa kusakaniza kumachepetsedwa, kupanga ndondomeko kumakhala kosavuta, ndipo kutsimikizira muyeso ndikolondola. Omwe amapanga makina olemera kwambiri ndi awa: French Schenck Company, Cloth Dabenla Company, French Pioneer Company, ndi zina zotero. Mfundo ya multihead weigher ndiyo kuchepetsa kulemera kosalekeza, ndiko kuti, kuchuluka kwa zipangizo zomwe zimasungidwa muzitsulo zoyezera; nkhokwe yoyezera imagwiritsa ntchito sensa yolemetsa kuyesa kulemera kwa ukonde kutembenuka pa nthawi ya unit, ndipo kutembenuka kwa kulemera kwa ukonde kumachokera ku galimoto yoyendetsa galimoto. Iwo ikuchitika pa yeniyeni kudya liwiro; nkhokwe yoyezera ndi kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake mapulogalamu okonzedwa ndi ukadaulo wosefera kuti apeze chandamale chachinyengo“enieni okwana otaya”, ndiyeno sinthani magawo akuluakulu ndi PID molingana ndi bolodi lowongolera, kuwerengera kwaposachedwa kuli pafupi ndi cholinga chonse, ndipo chizindikiro cha data chosinthira chimatuluka kuti chigwiritse ntchito choyambira chofewa, kuti mukwaniritse cholinga chosinthira kutulutsa kwathunthu kwa zida zogwiritsira ntchito. Zida za 300,000-ton polypropylene W804a-E ndizoyezera mitu yambiri, ndipo zopangira ziyenera kuyesedwa mosalekeza komanso molondola, ndiye kuti, payenera kukhala kuchuluka kwazinthu zopangira mu sikelo.

Sikelo yopanda kulemera imakhala ndi ma motors atatu, pomwe injini yaying'ono kwambiri W804a-E ndi injini yotulutsa extruder, ndiko kuti, mota yodyetsera. Ma motors apamwamba kapena akumbali ndi ma motors owongolera kuti achepetse zomata kapena milatho yanjanji. D804A-E Galimoto yomwe ili pansi pa hopper yosungiramo ndi chopangira chosakaniza kuti muchepetse kumamatira kwazinthu zopangira.

Mapeto apamwamba a hopper yosungiramo D804A-E ali ndi doko lodyetserako lokhala ndi grid kuyenda switch, yomwe imagwiritsidwa ntchito kudyetsa kugwiritsa ntchito valavu ya cylinder (valve ya butterfly). Kuchuluka kwa utsi ndi fumbi kungalepheretse ngozi za kuphulika. Zonse zakonzeka. Vavu yatsekedwa. Pamene chosungiracho chiyenera kuwonjezeredwa, chitseko cha dosing chimatsegulidwa ndipo valavu imatsegulidwa. Pali mabwalo ang'onoang'ono a emerald pafupi ndi multihead weigher pakompyuta, kukumbutsa kulemera kwapamwamba ndi kotsika kwa ukonde wa multihead weigher, kuti asayang'ane kutsegula ndi kutseka kwa valve yotsegulira, ndi chikumbutso chabe.

Malingana ndi kayendedwe ka pulogalamu, malire apamwamba ndi otsika a kulemera kwa ukonde wa zipangizo zopangira ntchito. Valavu yotsegula ya D804 imatsegulidwa ndi kutsekedwa, ndipo injini ya chipangizo choyambitsanso imayambika ndikuyimitsidwa; molingana ndi kulemera kwa ukonde wa multihead weigher, kuyeza kosalekeza ndi kolondola kumachitidwa kuti zitsimikizire kuti pali fungo lokwanira mu sikelo. Ma module omwe amagwiritsa ntchito multihead weigher ndi: kuyeza zida za VSE, gawo lolowera ndi lotulutsa VEA, ndi gawo la magwiridwe antchito a VLG. Malinga ndi momwe fakitale yathu ilili, popanga chiwembu, njira yolumikizirana pa intaneti yodziwika kwambiri imasankhidwa, ndipo pulogalamu yowongolera ya PLC yawonjezera ma module ndi ma protocol olumikizirana pamaneti okhudzana ndi kulumikizana kwapaintaneti.

Opaleshoni imasankha njira yopangira ma modular. Dongosolo lodziwongolera lokha limapangidwa ndi ma module osiyanasiyana, ndipo ma module osiyanasiyana owongolera amalumikizidwa molingana ndi mawonekedwe awo apakompyuta kuti asinthane deta ndi chidziwitso. Pulogalamu yoyang'anira idalembedwa mufakitole yoyambirira, ndipo idayikidwa mu chipangizo chopangira. Malinga ndi kope la zida zothandizira pulogalamu ya foni yam'manja EASYSERVEVPC, idalumikizana ndi gawo lowongolera pulogalamu yamapulogalamu molingana ndi kulumikizana kwa serial, ndipo magawo akulu adasinthidwa. Magawo akulu atsamba amathanso kuwonetsedwa ndikusinthidwa molingana ndi gawo la VLB lomwe mwasankha. Ntchito yeniyeniyo ndiyosavuta komanso yosavuta, kupewa njira yovuta polemba ndikusintha pulogalamu.

Kulemera kwa ukonde wa zipangizo zosungiramo katundu wolemera kumasinthidwa kukhala zizindikiro zamagetsi molingana ndi kachipangizo kolemera ndikutumizidwa ku gawo la VSE. Gawo loyezera zida VSE limafanizira ndikuzindikiritsa kulemera kwazinthu zopangira malinga ndi zomwe zidakonzedweratu kumtunda ndi kutsika kwa malire. Gwiritsani ntchito sluice ya chakudya kuti mudyetse nkhokwe yoyezera nthawi ndi nthawi. Kuphatikiza apo, gawo loyezera zida za VSE limafanizira kuchuluka kwa chakudya choyezera (chakudya chonse choyenda) ndi kuchuluka kwa chakudya chomwe chakhazikitsidwa, ndikusintha zida zodyera molingana ndi bolodi lowongolera ndi wowongolera (PID) kuti akwaniritse Zolondola zokhazikitsidwa pamitengo inayake ya chakudya. Chipata cha madzi odyetsa chimatsegula doko la chakudya, chimatseka liwiro la chakudya ndi chizindikiro cha data chowongolera, chimatseka kayendedwe ka chakudya ndi chizindikiro cha data chowongolera, chimatseka kutuluka kwa chakudya ndi chizindikiro cha deta yolamulira, ndikutseka kutuluka kwa chakudya ndi chizindikiro chowongolera deta. kutseka.

Chachiwiri, kusanthula ndi njira yothetsera mavuto omwe amapezeka a multihead weigher. 2.1 multihead weigher imasinthasintha kwambiri. Miyezo yolondola yasintha kangapo kuyambira pomwe idayamba kugwira ntchito mu 2005, ndipo mosiyana ndi cholakwika chachikulu chazomwe zidakhazikitsidwa, pansi pa weigher yamitundu yambiri, yasintha kwambiri pazaka zambiri.

(1) Ngati pali kusinthasintha pakuwonjezera zosungira zolimba pamanja, doko lodyetsera kumapeto kwa chosungirako cha D804A-E liyenera kutsegulidwa, apo ayi N2 idzalowa mu weigher yamitundu yambiri, yomwe ingawononge kutsimikizika kwa kuyeza, motero kuchititsa multihead weigher kuti asinthe. (2) Ngati chosungira cholimba changowonjezeredwa, chinthu choyamba kuyang'ana ndi ngati valve yolowera madzi yatsekedwa; kaya kusintha kwaulendo kumakhudza chilichonse ndichabwinobwino; kaya mpweya woperekedwa ku valavu yachipata ndi yabwinobwino; kaya valavu ya pneumatic yatsekedwa; Ngati zili zachilendo, onani ngati zotsatira zake zimasinthasintha. (3) Ngati pali kusinthasintha kwadzidzidzi pamene chirichonse chikuyenda bwino, choyamba fufuzani ngati pali dothi kuzungulira multihead wegher; fufuzani ngati pali zotupa kapena milatho ya njanji mu sikelo; fufuzani ngati galimoto yonyamula ma multihead weigher ikuyenda bwino; fufuzani ngati mbali zoyendera wononga makina zikuyenda bwino; Yang'anani kuti muwone ngati kutsegula kukuyenda bwino.

Mukayang'ana, chotsani choyezera mitu yambiri molingana ndi zomwe zili pamwambapa, ndikubwerezanso choyezera chamitundu yambiri. 2.2 Muyezo wolondola wa choyezera mitu yambiri ndi wotsika kapena wokwera kuposa mtengo womwe udayikidwiratu. Mu October 2008, multihead weigherW804B yokhala ndi 0 ~ 115kg / h inakumana ndi zovuta pamene mtengo wokonzedweratu unafika 50kg / h, ndipo mtengo woyezera wachangu nthawi zina umakhala wokhazikika pa 40kg / h, zomwe zinavulaza kwambiri. kupanga. Tsekani nthawi yomweyo.

Pankhani yamtengo wapatali wa 50kg / h, mlingo wa Schenck ukuyenda bwino, ndipo akukayikira kuti amayamba chifukwa cha zinthu zina, ndipo kufufuza kotsatiraku kukuchitika. Onetsetsani kuti kuyendetsa galimoto ya multihead weigher ndikwachilendo, wononga za extruder zoyendera zilibe zochitika zachilendo, ndipo palibe kutsekeka kwa dothi. Mulingo wazinthu za sikelo yopanda kulemera ndi yokhazikika, ndipo mtengo wapakati wa mpweya wabwino ndi wabwinobwino.

Ma waya a sensa yolemetsa samasuka, ndipo ma data a sensor yolemetsa ndi abwinobwino. Palibe zowunikira zomwe zili pamwambapa zomwe zapeza zomwe zimayambitsa kulephera. Ndinakumbukira kuti phula lotulutsa gawo la extruder lidasokonekera pomwe choyezera chambiri chidasinthidwa ndikukonzedwanso posachedwa. Mukagwetsa gawo loperekera wononga la extruder, zitha kuyambitsa kusintha kwa kulemera kwa ukonde.

Chitaninso kutsimikizira kwa data kwa multihead weigher. Pambuyo poyambira, zonse zimayenda bwino. Mtengo weniweniwo ndi wofanana ndi mtengo wokonzedweratu. Pambuyo pa kusanthula, choyezera chamagulu ambiri chimatchula kulondola kwakukulu kwa gawo loyezera ndi gawo loyendetsa. Zosintha zonse ziyenera kutsimikiziridwanso. , kuti atsimikizire kuti mtengo wake ndi wolondola. 2.3Multihead weigher nthawi zambiri amakhala pafupi kulephera. W804B nthawi zambiri imatsekedwa mu Novembala 2009. Zomwe zili mu alamu zikuwonetsa zomwe zili mu chidziwitso chodziwika bwino cha SC05, chomwe chimagwiritsidwa ntchito pazowopsa zowopsa zomwe zimachitika pazochitika zowopsa zakunja. Ogwira ntchito pazida zamagetsi adayang'ana kabati ya seva pakati pa zida zogawira magetsi ndipo adapeza kuti chosinthira chotuluka chidalumpha, zomwe zidachitika nthawi zambiri. Mipata yafupipafupi ndi kutseguka kwakukulu kumakhala zolakwika zambiri usiku; Pambuyo poyang'anitsitsa, zikuwoneka kuti mipata yomwe imakhalapo nthawi zambiri ndi kutseguka kwakukulu kumachitika chifukwa cha kuchulukidwa kwa multihead weigher, koma fufuzani kuti magalimoto oyendetsa magalimoto ambiri amazungulira bwino ndipo palibe kutsekeka kwa dothi.

Kuti muchepetse kulemera bwino, malire apansi a sikelo yolemetsa yoyambirira ndi 40kg ~ 50kg, yomwe imasinthidwa kukhala 30kg ~ 40kg, ndipo sikelo yopanda kulemera imasinthidwa kukhala 10kg. Ziwonetsero zitatu. Dongosolo lowongolera kulemera kwake ndi lothandiza, lodalirika pogwira ntchito, lolondola pakuyesa komanso kulephera kwa zida. Zotsatira zakhazikitsa maziko abwino a gawo lachiwiri la polojekitiyi, ndipo chiyembekezo cha msika cha chitukuko chake ndi chochititsa chidwi kwambiri.
