Leli phepha lichaza umqondo oyisisekelo kanye nendlela yokubala yokutholwa kokulinganisa isisindo se-multihead

Umbhali: Smartweigh–I-Multihead Weighter

I-software ye-othomathikhi ye-batching system iyisistimu yokulawula ebaluleke kakhulu, yokulinganisa kanye nokuhlonza ekubunjweni kwemboni yekhabhoni yenkampani, enomthelela omkhulu kwikhwalithi yemikhiqizo ekhiqizwa futhi icutshungulwe ngokufaka i-anodizing ku-carbon factory. Ukwakhiwa kwesikali (thula igama). Ngokocwaningo olujulile, imisebenzi yokuzijwayeza kwezenhlalo kanye nocwaningo lwesayensi lwezikali ezintathu ze-multihead, nginokuqonda okukha phezulu kanye nobuchule bezikali ze-multihead. Nasi isihluthulelo sokwenza isilinganiso esilula nesinemininingwane semiqondo eyisisekelo nezindlela zokubala zezikali ezintathu zamakhanda amaningi. Ngenisa futhi usebenze kanzima nawo wonke umuntu. Ukwakheka kwesakhiwo sokuqala.

Ngokuvamile, i-multihead weigher yakhiwa izingxenye ezibalulekile ezifana ne-feeding sluice, ibhakede elinesisindo, idivayisi enyakazayo, imishini yokuphakelayo, irack, i-load cell kanye nokulinganisa nokuhlola imishini yokusebenza yangempela. Ama-hopper amabili anesisindo. I-Weighing hopper ukufakwa kwezinto ezingavuthiwe esikalini sempahla eluhlaza. Ukukhethwa kwamamodeli wempahla eluhlaza kufanele kucabangele ukumelana nokugqwala kanye nokumelana ne-asidi. Ivolumu yesisindo sezinto zokusetshenziswa ikhethwa ngokuya ngenani eliphelele lokudla emizuzwini emi-3, futhi isikhathi sokudla kufanele sibhekane nayo yonke inqubo yokukala. 10% noma ngaphezulu.

Okwesithathu ukuxuba imishini. Isisetshenziswa esinyakazayo sisetshenziswa ikakhulukazi ukusiza ukuphakelwa kwezinto ezingavuthiwe ngokungabi namanzi. Ivamise ukwakhiwa ngenjini yokushayela yengalo ephukayo equkethe i-spiral auger blade noma amazinyo ezinzipho. Impahla eluhlaza yembobo iwela kahle ekungeneni nasekuphumeni. 4. Imishini yokuphakela.

Izinto zokuhamba zisetshenziselwa ukuthutha izinto zokusetshenziswa kwe-chemical fiber esikalini sebhalansi yokukala. Ngokuya ngezici zezinto zokusetshenziswa okufanele zithuthwe kanye nemvelo yendawo yohlelo lokusebenza, ama-screw conveyors, ama-centrifugal impeller conveyor, kanye namabhande okudlulisela amabhande angasetshenziswa. Ezimweni eziningi, ama-screw conveyors anamandla kuneminye imishini yokudla evaliwe futhi awakwazi nje ukuthutha izinto zokusetshenziswa ngokulinganayo, kodwa futhi avimbele ukuchaphazeka nokugeleza kwezinto ezingavuthiwe eziyimpuphu. Okwesihlanu uhlaka lokusekelwa kwekhadi lomsindo langaphandle.

Isakhiwo senzwa yomsindo yiphuzu lokusekela lezinye izinto zokusebenza zemishini kanye nemishini yomshini, futhi iseli yomthwalo ifakwe kuyo. 6. Inzwa yokukala Isisindo senetha siyingxenye ebalulekile yesisindo se-multihead weigher. Ikhetha inzwa yegeuge yokumelana nokulungiswa okuphezulu, eguqula isignali yesisindo senetha yezinto zokusetshenziswa ibe isignali yedatha yedivayisi ye-elekthronikhi ukuze ikhishwe. 7. Ukulinganisa nokuhlolwa kwemishini yokulawula.

Imishini yokulinganisa nokulawula yakhiwe ngokudayela kwesisindo se-multihead esihlakaniphile kanye nesistimu yokulawula ezenzakalelayo, esetshenziselwa ukulawula nokulinganisa izinga lokuhamba lezinto ezingavuthiwe namandla okuthutha. Ukwengeza, imbobo yokuphakela kanye nembobo yokuphakelayo yesisindo se-multihead kufanele ngokuvamile ikhethe ukulandela okuthambile ukumelana nokungcola nokuvala ukuxhumana okuthambile okuqhutshwayo ukuze kuqinisekiswe ukuthi ukuxhumana phakathi komgqomo wokugcina nezinto zokusebenza ezilandelayo akulula ukuvimbela ikala. I-hopper esindayo iyisikali se-multihead, futhi okuphakelayo okulungisekayo kufakwe kuseli lomthwalo eligxiliswe kuhlaka.

Okwesibili, indinganiso. Okokuqala, indinganiso. Ukuhlolwa kwe-metrological kusekelwe emcabangweni oyisisekelo wokulawula izingozi zesisindo sensalela kuyo yonke inqubo yomsebenzi.

Okokuqala, kala imishini yomshini wokusika kanye ne-hopper enesisindo, setha isivinini sokusika sangempela ngokusho kokulimala kwesisindo senetha ngesikhathi seyunithi, bese ulawula imishini yokusika ukuze wenze isivinini sangempela sokusika. Imingcele yokulawula inembile futhi iyaguquguquka, futhi ngesikhathi esifushane, imishini yomshini wokusika isebenzisa amandla okusebenzisana phakathi nayo yonke inqubo yokusika ukwenza amasignali okulawula agcinwe phakathi nezigaba zakamuva zomsebenzi zisebenza ngokuvumelana nomqondo oyisisekelo. yevolumu. Okwesibili ukukalwa kwenqubo yonke. Isisindo esinetha sezinto zokusetshenziswa ku-hopper yokukala siguqulwa sibe amadivaysi e-elekthronikhi ngokuya ngesisindo senzwa, futhi idatha idluliswa ngokungenantambo kukesi lesisila lamakhanda amaningi. Ngokuphambene, ngokusho kokulawulwa kwe-PLC kwesango lamanzi okuphakelayo, i-hopper enesisindo inqanyuliwe.

Ukwengeza, iphaneli yezinsimbi emotweni ekalayo iqhathanisa izinga lokuphakelayo elikalwe ngokunembile (ukugeleza okuvulayo) nezinga lokuphakela elisethiwe, futhi lisebenzisa ukulungiswa kwe-PID ukwenza umsebenzi wangempela wemishini yokuphakelayo nezinto zokusebenza, ukuze izinga lokuphakelayo langempela. ingalungiswa. Izinga lokuphakelayo lilandelela ngokunembile inani elisethwe kusengaphambili. Lapho isango lamanzi okuphakelayo livulwa ukuze liphakele ku-hopper yokukala, isignali yedatha yokulawula ivala izinga lokudla, futhi iqala ukuphakela ngevolumu. Ikesi lesisindo samakhanda amaningi libonisa okuqukethwe kolwazi lwezinto ezibonakalayo ezingenayo neziphumayo, libonisa inani langempela lezinto ezingenayo neziphumayo, futhi Ibonisa ulwazi mayelana nengqikithi yesisindo sezithako. Okwesithathu isilinganiso esinembile sezinga lokudla.

Izinga lokuphakela (ukugeleza kokuvula) le-multihead weigher inani lomonakalo wesisindo sensalela ngesikhathi seyunithi ngayinye, elibalwa ngokombono ngefomula ethi mt=dG/dt. Ijubane elikhulu lokusika; inani lengqikithi yomonakalo, okungukuthi i-dG ikala ngokunembile isikhathi dt. Isikali se-multihead singakala ngokunembile izinga lokuphasa ngokucindezela nokubamba ngaphansi kwesimo esibonisiwe.

mt=n(d±β*d1)/(t±t) Ifomula iyabalwa. Ukudayela kwesisindo se-d-multihead kubonisa ububanzi. Ulwazi lwe-n-Display lubonisa inani lokushintshwa okulinganiselwe kokuqukethwe kolwazi.

D1- Ukulungiswa kwesikrini kwesikrini sangaphakathi sephaneli yensimbi emotweni yokukala inani lenkomba yephutha lokulinganisa, elivame ukuboniswa ngu-β=O.6. I-TD - ukulinganisa okunembile kwesikhathi sohlelo lokujikeleza kwegazi. Te - inani lenkomba lesizathu sokurekhoda amaphutha ngesikhathi sokurekhoda, ngokuvamile te=0.001.

4. Bala isisindo esiphelele. Ingqikithi yesisindo senetha i-Gq esikhathini esiphelele somjikelezo we-multihead weigher inezingxenye ezimbili, okuyisivivinyo sokukala i-multihead weigher kanye nenetha yesisindo se-multihead weigher VA, kanye nenethi ye-multihead weigher yokudayela isisindo senetha engu-V engakalwa isigaba sangaphambilini. . gq=va+VD product=(umkhiqizo+umkhiqizo)-(umkhiqizo-umkhiqizo)-0CD=MTL*TF isibalo sefomula.

VH- Inani elingaphezulu lomkhawulo wesisindo esisele ngaphambi kokukala isitoko sempahla. Isizini - Isinongo sengqikithi yenani lomkhawulo eliphansi emgqonyeni wesisindo. $H - inani lomkhawulo esisindweni senetha ngenxa yephutha lesisindo.

Isisindo senetha singaphansi kwevelu elishiwo ngenxa yephutha elibangelwe ukukala. I-MTL - Izinga lokuphakelayo elikhiyiwe ngesikhathi sokuphakela. TF - isikhathi esilinganiselwe.

Izinga lokuphakelayo elikhiyiwe i-MTL lisaboniswa ngesisindo sengqikithi ngoshintsho lwe-K ngesekhondi Ububanzi bubonisa: mtl=K(d±β*d1)/(1±te) Isikhathi sokudla Ukondla isango lamanzi lokugeleza kokuphakela MF, MF=10MT. Isikhathi esiphelele se-TF=VA/MF sithi: TE=TF+TD. Isilinganiso sokugeleza esimaphakathi sithi: mq=gq/tn Esikhathini sesistimu yomjikelezo ngamunye, isisindo sengqikithi yezinto ezingavuthiwe sihlanganiswa ngokuqhubekayo, futhi isamba sengqikithi yesisindo se-tn ngaleso sikhathi t=0 singakalwa ngokunembile.

Okwesihlanu, imiphumela. Kweminye imishini yokukala nemishini ehlukahlukene, ngenxa yokuhlangana kwezinto ezingavuthiwe, ukuguqulwa kwezinga lokushisa kweseli lomthwalo kubangela ukuthi isisindo se-tare sishintshe, ngaleyo ndlela kunciphisa ukunemba kwesistimu, kodwa isikali se-multihead siyawaqeda amaphutha, futhi Kunzima Ukuguqulela ukunciphisa ukunemba kwesisindo. Isizathu silula kakhulu, ukulinganisa okunembile kwesilinganiso sokuphakela kwe-multihead weigher kusekelwe kumehluko wesisindo senetha, hhayi umehluko wesisindo senetha, ngakho-ke i-multihead weigher inethuba elibanzi kakhulu lesicelo ohlelweni lwezokuthutha lwe-chemical fiber eluhlaza.
