Isikali samakhanda amaningi sibala kanjani inhlanganisela?

Ubuchwepheshe buye babumba imikhakha ebalulekile eminyakeni edlule, okuhlanganisa nemboni yokupakisha. Izikali ze-multihead zisetshenziswa kabanzi kuwo wonke amabhizinisi, futhi imiphumela ikhiqizwa ngendlela elawulwa kakhulu futhi enembile eyenziwe ngekhompyutha encane. Izikali ze-multihead nazo zibizwa ngokuthi izikali ezihlanganisiwe ngoba umsebenzi wazo ukukhipha inhlanganisela engcono kakhulu yesisindo somkhiqizo.

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

Ukuze kubalwe inhlanganisela, isikali samakhanda amaningi sisebenzisa uhlelo lwekhompyutha oluhlelwe ngesisindo esiqondiwe somkhiqizo ozokhishwa kanye nesisindo somkhiqizo ngamunye. Uhlelo lusebenzisa lolu lwazi ukuthola inhlanganisela efanele yemikhiqizo ukuze kufezwe isisindo esiqondiwe.

Lolu hlelo luphinde lucabangele izici ezahlukahlukene njengobuningi bomkhiqizo, izici zokugeleza, kanye nesivinini esifunekayo somshini. Lolu lwazi lusetshenziselwa ukwenza ngcono inqubo yokulinganisa nokuqinisekisa ukunikezwa komkhiqizo okunembile nokuphumelelayo.

Isikali samakhanda amaningi sisebenzisa inqubo ebizwa ngokuthi "inhlanganisela yokulinganisa" ukuze kutholakale inhlanganisela efanele yemikhiqizo okufanele ikhishwe. Lokhu kuhilela ukukala isampula encane yomkhiqizo nokusebenzisa ama-algorithms ezibalo ukuze kutholakale inhlanganisela ephumelela kakhulu yemikhiqizo ezofinyelela isisindo esiqondiwe.

Uma inhlanganisela efanele isitholakele, isikali samakhanda amaningi sihambisa imikhiqizo esikhwameni noma esitsheni, silungele ukupakishwa. Yonke inqubo izenzakalelayo kakhulu futhi ingaqedwa ngemizuzwana embalwa, okwenza izikali zamakhanda amaningi zibe ukukhetha okuthandwayo kwemisebenzi yokupakisha ephezulu.

Isenzo esiyinhloko senzeka lapho umkhiqizo usatshalaliswa ngokulinganayo. Umsebenzi oyinhloko we-linear feeder ukuletha imikhiqizo ku-feed hopper lapho isenzo senzeka khona. Isibonelo, ku-multi-weiger enamakhanda angu-20, kufanele kube nama-linear feeder angu-20 aletha imikhiqizo kuma-feed hopper angu-20. Lokhu okuqukethwe ekugcineni kuthululwa ku-weigh hopper, ene-load cell. Ikhanda ngalinye le-weigh line-weigh cell yalo enembile. Leli cell le-load lisiza ukubala isisindo somkhiqizo ku-weigh hopper. I-multihead weigher ifakwe iprosesa ekugcineni ebala inhlanganisela engcono kakhulu yazo zonke izisindo ezitholakalayo ezidingekayo ukuze kufezwe isisindo esifunwayo.

Kuyiqiniso elaziwayo ukuthi amakhanda anesisindo esiningi akhona emshinini wakho wokulinganisa amakhanda amaningi aholela ekukhiqizweni okusheshayo kokuhlanganiswa. Izingxenye ezilinganiswe kahle zanoma yimuphi umkhiqizo zingakhiqizwa ngesikhathi esifanayo. Isikali esijwayelekile sekhanda elilodwa sisendleleni yokufinyelela isisindo esifiselekayo. Izinga lokuphakelwa alikwazi ukushesha kakhulu ukuqinisekisa ukunemba. Ezimweni eziningi, inani lezinto eziku-hopper ngayinye libekwe ku-1/3 kuya ku-1/5 yesisindo esiqondiwe.

Ngesikhathi sokubalwa kwesikali sokuhlanganiswa, kusetshenziswa inhlanganisela engaphelele kuphela. Inani lamakhanda ahlanganyela enhlanganiselani lingalinganiselwa kusetshenziswa ifomula: n=Cim=m! / I! (m - I)! Lapho u-m kuyinani eliphelele lama-hopper okukala enhlanganiselani, futhi u-I umele inani lamabhakede ahilelekile. Ngokuvamile, njengoba u-m, u-I, kanye nenani lenhlanganisela engenzeka likhula, ukuthola umkhiqizo omuhle kuyanda.

Isikali sakho samakhanda amaningi singenziwa ngokwezifiso ngezithasiselo ezahlukahlukene zokuzikhethela ukuqinisekisa ukuthi sisebenza kahle ngemikhiqizo ehlukahlukene. I-timing hopper iyona evame kakhulu kule misebenzi. I-timing hopper iqoqa umkhiqizo okhishwe kuma-weigh hopper bese iwubamba kuze kube yilapho umshini wokupakisha uqondisa/ukhombisa ukuthi uvuleka. Kuze kube yilapho i-timing hopper isivuliwe futhi ivaliwe, isikali samakhanda amaningi ngeke sikhiphe noma yimuphi umkhiqizo kuma-weigh hopper. Sisheshisa inqubo ngokunciphisa ibanga phakathi kwesikali samakhanda amaningi kanye nemishini yokupakisha. Enye inzuzo eyengeziwe ama-booster hopper, aziwa nangokuthi ungqimba olwengeziwe lwama-hopper angeziwe ukugcina umkhiqizo osuvele ulinganisiwe ku-weight hopper. Lo mkhiqizo awusetshenziswa esikalini, okwandisa inhlanganisela efanele etholakalayo ohlelweni futhi kwandisa isivinini nokunemba.
