Wolemba: Smartweigh-Multihead Weighter

Ndi kuwongolera kwanthawi zonse komanso kulondola kwazomwe zimatsimikizira kutsimikizika kwa metrological paziwiya, makamaka zida zolimba, mtundu watsopano wa zida zotsimikizira ma metrological.——Makina otsimikizira ma metrological state opanda kulemera adakhalapo mu 1990s. Multihead weigher mosalekeza ndikuyesa ndendende zinthu zopangira malinga ndi kusintha kwa kulemera kwa ukonde wazinthu zopangira pa sikelo. Kutuluka kwa multihead weigher pang'onopang'ono kunalowa m'malo mwa sikelo yoyambirira ya lamba wamagetsi, sikelo yozungulira komanso sikelo yonse.

Monga njira yatsopano yoyezera komanso yowonjezereka, yakhala ikugwiritsidwa ntchito kwambiri m'makampani azitsulo, migodi, chomera chamankhwala ndi mafakitale amagetsi amagetsi. Pulatifomu yoyezera zoyezera, bin yodyetsera ndi makina onse ndi zida zomwe zimagwira ntchito papulatifomu yoyezera zimagwiritsidwa ntchito ngati thupi lonse lolemera, ndipo sensa imatumiza mosalekeza kusintha kwa kulemera kwa ukonde pa thupi lolemera kupita ku manipulator oyezera ma multihead (manipulator ndi fungulo la choyezera chamitundu yambiri Gawo la yankho, kusintha konse ndikuwongolera kumachitika ndi icho). Chida chowongolera chimawerengera kuchuluka kwa kulemera kokwanira kwa sikelo ya thupi pa nthawi ya unit malinga ndi chizindikiro cha data monga momwe zimakhalira nthawi yomweyo, ndikufanizira ndi zomwe zimayendera.

Pambuyo PID mawerengeredwe, linanena bungwe 4-50mA panopa deta chizindikiro, kusintha linanena bungwe pafupipafupi wa kudyetsa galimoto inverter, ndiyeno kusintha chiŵerengero galimoto liwiro, kotero kuti kudyetsa yeniyeni kuchuluka ndi kuyandikira monga kotheka kwa akonzedwa wonse chandamale otaya okwana, kotero monga kukwaniritsa zolondola Kopita chakudya. Kuti mutsirize kudyetsa mosalekeza ndi kuyezetsa koyezera koyezera koyezera mutu wambiri, cholumikizira chachikulu choperekera chakudya mosalekeza ndi valavu yodziwikiratu yodyetsera iyenera kuyikidwa pa nkhokwe yodyera. Pali malire apamwamba (recharge_terminated) ndi mtengo wotsika (recharge_started) mu mita yolamulira.

Kulemera kwa ukonde pa sikelo kukafika pamtengo wotsika, chizindikiro chidzatumizidwa kuti chitsegule valavu yotsegulanso, valavu yotsegulanso idzatsegulidwa, zipangizo zomwe zili m'nyumba yosungiramo katundu zidzatsitsidwa ku nkhokwe yosungiramo katundu malinga ndi kugwirizana kwa conductive flexible. , ndipo kulemera kwa ukonde pa sikelo kudzawonjezeka. Pamene kulemera kwa ukonde pamlingo kufika pamtengo wowonjezeranso, apa mu ndondomeko yonseyi, galimoto yodutsa imagwira ntchito kuyambira pachiyambi mpaka kumapeto, zomwe zikutanthauza kuti chiphasocho chikupitirirabe. Kwa zopangira zokhala ndi kufalikira kosakwanira, kulemera kopepuka ndi kulemera kopepuka, sikophweka kuwonjezera gawo la ukonde wolemera ku thupi la sikelo mu nthawi yochepa valavu yachipata itatsekedwa.

Panthawiyi, ngati woyezera ma multihead weigher akuyendetsa PID molingana ndi chizindikiro cha data chomwe chimaperekedwa ndi sensa, kusintha kwa kulemera kwa ukonde komwe kumadziwika ndi sensa panthawiyi kudzachepetsedwa, zomwe zimapangitsa kuti pakhale kutayika kwa chidziwitso cha deta. Choncho, palinso kuchedwa kwa nthawi ya chakudya (timer 2) mu chida chowongolera, chomwe chimayamba nthawi kuchokera kutseka kwa valve yachipata. Panthawi yoyambira kudyetsa mpaka kumapeto kwa kuchedwa kwa nthawi yodyetsa, makina odyetsera amasunga pafupipafupi asanadye, ndiye kuti, choyezera chamitundu yambiri chikugwira ntchito pafupipafupi - static data manipulation.

Nthawi yodyetsera ikatha, choyezera cha multihead chimangobwezeretsa nthawi yeniyeni, ndiko kuti, imagwira ntchito yodyetsa molingana ndi chizindikiro cha data chomwe chimatumizidwa ndi sensa. Njira yogwiritsira ntchito multihead weigher ikuchitika motere. Pofuna kuonetsetsa kuti mzere wa multihead weigher umagwirizana bwino, kuwonjezera pazigawo zazikuluzikulu, palinso magawo akuluakulu otsatirawa mu chida chowongolera: SetP (proportional coefficient p value); kuphatikiza mtengo wa nthawi; SetD (chizindikiro chosiyana cha nthawi d mtengo); Caltime (nthawi yanthawi yotsatsira yanthawi zonse); Calcount (nthawi yanthawi yowerengera yowerengera); kuwunika koyang'anira kuthamanga; malire E (kulekerera kupatuka kosiyanasiyana kuwunika koyenda); high_net kulemera (mtengo wapamwamba wazinthu); low_net kulemera (kulemera kwapakatikati-kuchuluka kwamtengo wapatali (pafupifupi malire); katundu wocheperako (pafupifupifupifupi); chitsanzo chonse chotuluka 1 (kuwongolera mphamvu zonse zotuluka 1); chitsanzo chonse chotuluka 2 (kuwongolera mphamvu zonse 2); chitsanzo chonse chotuluka 3 (kuwongolera kwamphamvu kuchuluka kwamayendedwe 3); njira yogwirira ntchito (kusankha njira yogwirira ntchito); kusankha kwamisa (gulu lalikulu (kusanthula kuchuluka) kusankha ntchito); koyenekera yotuluka (gawo lalikulu la kuwerengera kwathunthu); Ratio factor (yaiwisi yazinthu zofananira main parameter).

4 Mafunso Ofunsidwa Kawirikawiri mu Multihead Weigher Design Schemes. Kuti muwongolere bwino mzere wa weigher wa multihead, zinthu zotsatirazi ziyenera kuganiziridwa mu dongosolo la mapangidwe: 1) Sankhani maulendo oyenerera ogwiritsira ntchito ndikusunga mafupipafupi pakati pa 35HZ ndi 40HZ ngati abwino kwambiri. Pamene mafupipafupi ali otsika kwambiri, kudalirika kwa pulogalamu ya pulogalamu kumakhala koyipa; 2) Kusankhidwa kwa mtundu wa kuyeza kwa sensa ndi koyenera, mawonekedwe ogwiritsira ntchito ndi 60% ~ 70%, ndipo kutembenuka kwa chizindikiro cha deta ndi kwakukulu, komwe kumapindulitsa kuwongolera mzere; 3) The makina dongosolo kapangidwe dongosolo ayenera kuonetsetsa kuti zopangira Good kufalitsidwa, yochepa kudya nthawi.

Kudyetsa sikuyenera kuchulukirachulukira, ndipo nthawi zambiri kumaperekedwa kudyetsa mphindi zisanu kapena khumi zilizonse; 4) Chida chopatsirana chophatikizika chiyenera kuwonetsetsa kuti chikugwira ntchito mokhazikika komanso njira yabwino kwambiri. 5Multihead weigher kukhazikitsa ndi kugwiritsa ntchito mavuto wamba: Kuti muwonetsetse kulondola kwa weigher ya multihead, mfundo zazikuluzikulu zotsatirazi ziyenera kutsatiridwa pakuyika ndikugwiritsa ntchito: 1) Pulatifomu yoyezera iyenera kukhazikika komanso yolimba, sensor ndi zotanuka deformation chigawo chimodzi, kukhudzidwa ndi kugwedera kunja. Zomwe zachitika pantchito zikuwonetsa kuti chinthu choyipa kwambiri pakugwiritsa ntchito choyezera mitu yambiri ndikuwononga kugwedezeka kwachilengedwe; 2) Pasakhale chimphepo chamkuntho m'chilengedwe, chifukwa pofuna kupititsa patsogolo kulemera kwake, sensa yosankhidwa ndi yanzeru kwambiri, choncho zolakwa zonse zowamba Zonse zidzakhudza sensa; 3) Kulumikizana kofewa kochititsa chidwi kumanzere ndi kumanja kuyenera kukhala kofewa kuti tipewe kutengera kumanzere ndi kumanja pa choyezera chambiri.

Zopangira zabwino kwambiri panthawiyi ndizosalala, zofewa komanso zamphamvu za satin; 4) Kuchepetsa mtunda wolumikizana pakati pa hopper yayikulu ndi hopper yapamwamba, ndibwino. Makamaka zida zopangira zomatira mwamphamvu, kutalika kwa mtunda wolumikizana pakati pa hopper yayikulu ndi silo yakumtunda, zida zambiri zimamatira ku makulidwe a khoma. Pamene zinthu za mankhwala pa khoma makulidwe amamatira pa mlingo winawake, kamodzi iwo kugwa, izo zidzakhudza kwambiri wolemera multihead; 5) Yesetsani kupewa kukhudzana ndi kunja, ndipo kulemera kwa ukonde wa kunja kwa sikelo kuyenera kusungidwa. 6) Mlingo wodyetsera uyenera kukhala wofulumira, kotero ndikofunikira kuwonetsetsa kudyetsa kosalala panthawi yonse yodyetsa.

Kwa zipangizo zomwe sizikuyenda bwino, kuti mupewe bwino milatho ya njanji, njira yabwino yothetsera vutoli ndikuwonjezera makina oyendetsa m'nyumba yosungiramo katundu. Choyipa chachikulu ndichakuti chimphepocho chimachotsa arc, koma kusakanikirana sikungachitike nthawi zonse. Choyenera kwambiri ndikusunga njira yonse yosakaniza ndi kudyetsa mofanana, ndiko kuti, kusunga mofanana ndi valve yodyetsa; 7) Mtengo wotsika wa malire ndi mtengo wapamwamba wa zipangizo zothandizira zimayikidwa momwe zingathere, ndipo chitsogozo chokhazikitsa ndi tebulo la zipangizo mu silo. Kachulukidwe kameneka pano ndi chimodzimodzi pakati pa kuchuluka kwa zinthu ziwirizi.

Izi zitha kupezeka poyang'anitsitsa kusintha kwafupipafupi kwa choyambira chofewa. Pamene kachulukidwe kowoneka bwino kwa zopangira mu silo kumakhala kofanana, pafupipafupi maziko a choyambira chofewa sichisintha kwambiri. Kukonzekera koyenera kwa mtengo wotsika wa malire ndi mtengo wapamwamba wa kudyetsa kungathe kupititsa patsogolo mzere mu ndondomeko yonse yodyetsera, chifukwa zanenedwa kale kuti multihead weigher ili mu static data control panthawi yodyetsa, ngati kumanzere ndi kumanzere. zoyambira zofewa zamanja isanayambe komanso itatha kudyetsa Maziko afupipafupi sangasinthe, ndipo kulondola kwa muyeso pa nthawi yonse yodyetsa kumatsimikiziridwa.

Kuonjezera apo, pamene kachulukidwe kachulukidwe kameneka kamakhala kofanana, yesetsani kupewa kudyetsa pafupipafupi, ndiko kuti, kudyetsa zipangizo zambiri panthawi imodzi momwe mungathere. Ziwirizi ndizosiyana ndipo ziyenera kuganiziridwa zonse. Izi ndizofunikanso kuti zitsimikizire kulondola kwa njira yonse yodyetsera; 8) Kukhazikitsa kuchedwa kwa nthawi yodyetsera ndikokwanira.

Malangizo enieni pakukhazikitsa ndikuwonetsetsa kuti zida zonse zili pamlingo, ndipo nthawi yocheperako imakhala yabwinoko. Ndamva kuti choyezera ma multihead chili mukusintha kwa data mkati mwa kuchedwa kwa nthawi ya chakudya, ndiye kuti nthawi yocheperako imakhala bwino. Nthawiyi imathanso kuwonedwa mosamala.

Panthawi yosintha, mutha kukhazikitsa nthawi yochedwa nthawi yayitali, ndikuwona kuti kulemera konse kwa sikelo kumatha kukhazikika nthawi yayitali bwanji popanda kusinthasintha (osati kuwonjezereka) mukangowonjezeranso (kulemera konse kwa sikelo kumachepa bwino). Ndiye nthawi iyi ndi yoyenera kudyetsa nthawi kuchedwa. 6. Zotsatira.

Mau Oyamba: Pepalali likufotokoza mwatsatanetsatane mfundo ya multihead weigher ndi zovuta zina zomwe zimachitika pakupanga ndi kugwiritsa ntchito, makamaka mfundo zazikuluzikulu pakugwiritsa ntchito. Ndi ntchito yamtengo wapatali, ndipo ndikuyembekeza kukuthandizani Ndi chithandizo china, choyezera mutu wambiri chingagwiritsidwe ntchito bwino. Pokhapokha pakuyika kufunikira kwakukulu ku mfundo yovutayi m'pamene kuti mzere wa multihead weigher ukhoza kutsimikiziridwa ndi kupanga katundu wapamwamba kwambiri.
