Isikali se-multihead sizibala kanjani izinhlanganisela?

Ubuchwepheshe bumise imikhakha ebalulekile eminyakeni edlule, okuhlanganisa nemboni yokupakisha.Izikali eziningiasetshenziswa kabanzi kuwo wonke amabhizinisi, futhi imiphumela ikhiqizwa ngendlela elawulwa kakhulu nenembayo eyakhiwe nge-microcomputer. Izikali ze-Multihead nazo zibizwa ngokuthiizikali ezihlanganisiwengoba umsebenzi wabo ukuthatha inhlanganisela engcono kakhulu yesisindo somkhiqizo.

I-multihead weigheringumshini osetshenziswa embonini yokupakisha ukukala nokukhipha imikhiqizo efana nokudla, imithi, namakhemikhali. Iqukethe amakhanda okukala amaningi (ngokuvamile aphakathi kuka-10 no-16), ngalinye liqukethe iseli lomthwalo, elisetshenziselwa ukukala isisindo somkhiqizo.

Ukuze ubale izinhlanganisela, isikali se-multihead sisebenzisa uhlelo lwekhompiyutha oluhlelwe ngesisindo esihlosiwe somkhiqizo ozokhishwa kanye nesisindo somkhiqizo ngamunye. Uhlelo lusebenzisa lolu lwazi ukuze lunqume inhlanganisela efanele yemikhiqizo ukuze kuzuzwe isisindo esihlosiwe.

Uhlelo futhi lubheka izici ezahlukahlukene njengokuminyana komkhiqizo, izici zokugeleza, kanye nesivinini esifiswayo somshini. Lolu lwazi lusetshenziselwa ukuthuthukisa inqubo yokukala futhi kuqinisekiswe ukukhishwa okunembile nangempumelelo komkhiqizo.

Isilinganiso se-multihead sisebenzisa inqubo ebizwa ngokuthi "isisindo esihlanganisiwe" ukuze sinqume inhlanganisela efanele yemikhiqizo ezokhishwa. Lokhu kuhilela ukukala isampula encane yomkhiqizo nokusebenzisa izibalo zokunquma ukunquma inhlanganisela esebenza kahle kakhulu yemikhiqizo ezofinyelela isisindo esiqondiwe.

Uma inhlanganisela efanele isinqunyiwe, isikali se-multihead sikhipha imikhiqizo esikhwameni noma esitsheni, esilungele ukupakishwa. Yonke le nqubo i-othomathikhi kakhulu futhi ingaqedwa endabeni yemizuzwana, okwenza izikali ze-multihead zibe yisinqumo esidumile semisebenzi yokupakisha yevolumu ephezulu.

Isenzo esiyinhloko senzeka lapho umkhiqizo usatshalaliswa ngokulinganayo. Umsebenzi oyinhloko we-feeder yomugqa ukuletha imikhiqizo ku-hopper yokuphakelayo lapho isenzo senzeka khona. Isibonelo, ku-multi-head weigher enamakhanda angama-20, kufanele kube neziphakeli eziqondile ezingama-20 eziletha imikhiqizo kuma-feed hopper angama-20. Lokhu okuqukethwe ekugcineni kuthululelwa ku-weigh hopper, eneseli yomthwalo. Ikhanda ngalinye lesisindo linengqamuzana lalo lesisindo esinembayo. Le cell cell isiza ukubala isisindo somkhiqizo ku-hopper yesisindo. I-multihead weigher ifakwe iphrosesa egcina ibala inhlanganisela engcono kakhulu yazo zonke izisindo ezitholakalayo ezidingekayo ukuze kuzuzwe isisindo esiqondisiwe.

Kuyiqiniso elaziwayo ukuthi amakhanda anesisindo esiningi akhona emshinini wakho wokukala amakhanda amaningi kubangela inhlanganisela esheshayo yesizukulwane. Izingxenye ezikalwe ngokunembile zanoma yimuphi umkhiqizo zingakhiqizwa ngesikhathi esifanayo. Isilinganiso esijwayelekile sekhanda elilodwa sisendleleni yokuzuza isisindo esifunekayo. Izinga lokudla alikwazi ukushesha kakhulu ukuqinisekisa ukunemba. Ezimweni eziningi, inani lempahla ku-hopper ngayinye lisethwe ku-1/3 kuya ku-1/5 wesisindo somgomo.

Ngesikhathi kubalwa isikali esihlanganisiwe, kusetshenziswa izinhlanganisela eziyingxenye kuphela. Inani lamakhanda abamba iqhaza ekuhlanganisweni lingalinganiswa kusetshenziswa ifomula: n=Cim=m! / ngi! (m- ngi)! Lapho u-m iyinani eliphelele lama-hopper anesisindo enhlanganisela, futhi ngimele inani lamabhakede ahilelekile. Ngokuvamile, njengoba m, mina, kanye nenani lezinhlanganisela ezingenzeka zikhula, ukuthola umkhiqizo omuhle kuyanda.

Isikali sakho se-multihead singenziwa ngendlela oyifisayo ngezengezo ongazikhethela ukuze kuqinisekiswe ukuthi sisebenza kahle ngemikhiqizo eyahlukene. I-hopper yesikhathi ijwayeleke kakhulu kule misebenzi. I-hopper yesikhathi iqoqa umkhiqizo okhishwe kuma-weigh hopper futhi iwubambe kuze kube yilapho umshini wokupakisha uqondisa/uwubonisa ukuthi uvule. Kuze kube yilapho i-hopper yesikhathi ivuliwe futhi ivaliwe, isikali esinamakhanda amaningi ngeke sikhiphe noma yimuphi umkhiqizo kuma-hopper wesisindo. Isheshisa inqubo ngokunciphisa ibanga phakathi kwe-multi-head weigher kanye nemishini yokupakisha. Enye inzuzo eyengeziwe i-booster hoppers, eyaziwa nangokuthi ungqimba olwengeziwe lwama-hoppers angezwe ukugcina umkhiqizo osuvele ulinganisiwe ku-hopper yesisindo. Lo mkhiqizo awusetshenziswa esikalini, ukhuphula izinhlanganisela ezifanele ezitholakala ohlelweni futhi ukhulise isivinini nokunemba.
