Kodi choyezera mitu yambiri chimawerengera bwanji kuphatikiza?

Ukadaulo wasintha magawo akuluakulu m'zaka zapitazi, kuphatikizapo makampani opanga ma CD. Zoyezera zamitundu yosiyanasiyana zimagwiritsidwa ntchito kwambiri m'mabizinesi onse, ndipo zotsatira zake zimapangidwa kudzera munjira yolamulidwa bwino komanso yolondola yopangidwa ndi makompyuta ang'onoang'ono. Zoyezera zamitundu yosiyanasiyana zimatchedwanso zoyezera zophatikizana chifukwa ntchito yawo ndikutenga kuphatikiza koyenera kwa kulemera kwa chinthu.

Cholemera cha mitu yambiri ndi makina omwe amagwiritsidwa ntchito mumakampani opanga zinthu zolemetsa polemera ndikupereka zinthu monga chakudya, mankhwala, ndi mankhwala. Chimakhala ndi mitu yambiri yolemera (nthawi zambiri pakati pa 10 ndi 16), iliyonse ili ndi selo yolemetsa, yomwe imagwiritsidwa ntchito kuyeza kulemera kwa chinthucho.

Kuti awerengere kuphatikiza, choyezera mitu yambiri chimagwiritsa ntchito pulogalamu ya pakompyuta yomwe imakonzedwa ndi kulemera komwe kukufunika kuti chinthucho chiperekedwe komanso kulemera kwa chinthu chilichonse. Pulogalamuyi imagwiritsa ntchito izi kuti idziwe kuphatikiza kwabwino kwa zinthu kuti zikwaniritse kulemera komwe kukufunika.

Pulogalamuyi imaganiziranso zinthu zosiyanasiyana monga kuchuluka kwa zinthu, momwe zimayendera, komanso liwiro lomwe makinawo amafunikira. Izi zimagwiritsidwa ntchito pokonza njira yoyezera zinthu ndikuwonetsetsa kuti zinthuzo zikupezeka molondola komanso moyenera.

Cholemera cha mitu yambiri chimagwiritsa ntchito njira yotchedwa "combination weighing" kuti chidziwe kuphatikiza koyenera kwa zinthu zoti ziperekedwe. Izi zimaphatikizapo kuyeza chitsanzo chaching'ono cha chinthucho ndikugwiritsa ntchito ma algorithms owerengera kuti chidziwe kuphatikiza kogwira mtima kwambiri kwa zinthu zomwe zingakwaniritse kulemera komwe mukufuna.

Akapeza njira yabwino yogwiritsira ntchito, choyezera cha mitu yambiri chimagawira zinthuzo m'thumba kapena m'chidebe, chokonzeka kupakidwa. Ntchito yonseyi imachitika yokha ndipo imatha kutha mumasekondi ochepa, zomwe zimapangitsa kuti zoyezera za mitu yambiri zikhale njira yotchuka yogwiritsira ntchito popakira zinthu zambiri.

Ntchito yaikulu imachitika pamene chinthucho chagawidwa mofanana. Ntchito yaikulu ya linear feeder ndikupereka zinthu ku feed hopper komwe chinthucho chimachitikira. Mwachitsanzo, mu 20-head multi-weighter, payenera kukhala ma linear feeder 20 omwe amapereka zinthu ku ma feed hopper 20. Zomwe zili mkati mwake pamapeto pake zimatsanuliridwa mu weigh hopper, yomwe ili ndi load cell. Mutu uliwonse wolemera uli ndi rightly weigh cell yake. Load cell iyi imathandiza kuwerengera kulemera kwa chinthucho mu weigh hopper. Wolemera mitu yambiri ali ndi purosesa yomwe pamapeto pake imawerengera kuphatikiza kwabwino kwambiri kwa zolemera zonse zomwe zilipo kuti akwaniritse kulemera komwe akufuna.

Ndi zoona kuti mitu yolemera kwambiri yomwe ilipo pa makina anu olemera mitu yambiri imapangitsa kuti pakhale kupanga kophatikizana mwachangu. Zigawo zolemera molondola za chinthu chilichonse zitha kupangidwa nthawi yomweyo. Sikelo yonse ya mutu umodzi ikupita kukapeza kulemera komwe mukufuna. Kuchuluka kwa chakudya sikungakhale kofulumira kwambiri kuti kutsimikizire kulondola. Nthawi zambiri, kuchuluka kwa zinthu zomwe zili mu hopper iliyonse kumayikidwa pa 1/3 mpaka 1/5 ya kulemera komwe mukufuna.

Pakuwerengera choyezera chophatikiza, kuphatikiza pang'ono kokha kumagwiritsidwa ntchito. Chiwerengero cha mitu yomwe imagwira ntchito mu kuphatikiza chingayesedwe pogwiritsa ntchito fomula iyi: n=Cim=m! / I! (m - I)! Pamene m ndi chiwerengero chonse cha ma hopper olemera mu kuphatikiza, ndipo I imayimira chiwerengero cha zidebe zomwe zikugwiritsidwa ntchito. Kawirikawiri, pamene m, I, ndi chiwerengero cha kuphatikiza komwe kungatheke chikukula, kupeza chinthu chabwino kumawonjezeka.

Choyezera chanu cha mitu yambiri chikhoza kusinthidwa ndi zinthu zosiyanasiyana kuti zitsimikizire kuti chikugwira ntchito bwino ndi zinthu zosiyanasiyana. Choyezera nthawi ndiye chinthu chodziwika bwino pa ntchito izi. Choyezera nthawi chimasonkhanitsa chinthu chomwe chatulutsidwa kuchokera ku zoyezera ndikuchigwira mpaka makina opakira atalamula/kuchiwonetsa kuti chitseguke. Mpaka choyezera nthawi chitseguke ndikutseka, choyezera cha mitu yambiri sichitulutsa chinthu chilichonse kuchokera ku zoyezera. Chimafulumizitsa njirayi mwa kufupikitsa mtunda pakati pa choyezera cha mitu yambiri ndi zida zopakira. Phindu lina lowonjezera ndi ma booster hopper, omwe amadziwikanso kuti ndi gawo lowonjezera la ma hopper omwe amawonjezedwa kuti asunge chinthu chomwe chayesedwa kale mu choyezera. Chogulitsachi sichikugwiritsidwa ntchito mu choyezera, zomwe zimawonjezera kuphatikiza koyenera komwe kulipo pamakina ndikuwonjezera liwiro ndi kulondola.
