Umbhali: Smartweigh–I-Multihead Weighter

Ngokuthuthukiswa kwemithethonqubo eqhubekayo nenembayo yokulawula ukuqinisekiswa kwe-metrological yezinto zokusetshenziswa, ikakhulukazi izinto zokusetshenziswa eziqinile, uhlobo olusha lwemishini yokuqinisekisa i-metrological——Imishini yokuqinisekisa i-metrological yesimo esingenasisindo kanye nemishini yaba khona ngeminyaka yawo-1990. Isisindo se-multihead ngokuqhubekayo futhi silinganisa ngokunembile impahla eluhlaza ngokuya ngoshintsho lwesisindo senetha lempahla eluhlaza emzimbeni wesikali. Ukuvela kwe-multihead weigher kancane kancane kwashintsha isikali sokuqala sebhande le-electronic, isikali esivunguzayo kanye nesikali esiphelele.

Njengendlela yokulinganisa entsha nethuthukisiwe, isetshenziswe kabanzi embonini ye-metallurgical, izimayini, imboni yamakhemikhali kanye nemboni yamakhemikhali ye-fiber energy. Inkundla yesevisi yokukala, umgqomo wokuphakela kanye nayo yonke imishini nemishini esebenza endaweni yesevisi yokukala kusetshenziswa njengomzimba wonke wokukala, futhi inzwa idlulisela ngokuqhubekayo ukuguqulwa kwesisindo senetha emzimbeni wesisindo kuya kusikhohlisa sesisindo samakhanda amaningi (i-manipulator ukhiye we-multihead weigher Ingxenye yesixazululo, konke ukukhohlisa nokuxazulula kwenziwa yiso). Ithuluzi lokulawula libala ingqikithi ye-coefficient enwebekayo yesisindo somzimba wesilinganiso ngesikhathi seyunithi ngokuya ngesignali yedatha njengokugeleza okuphelele okuqondile okukhona ngaleso sikhathi, bese iqhathanisa nokugeleza okuphelele kwethagethi esethiwe.

Ngemuva kokubala kwe-PID, okukhipha isignali yedatha ye-4-50mA yamanje, shintsha imvamisa yokuphuma kwe-inverter ye-motor, bese ushintsha isilinganiso sesivinini semoto, ukuze inani elithile lokuphakela lisondele ngangokunokwenzeka ekugelezeni okuphelele okuhlosiwe okuhlosiwe, ukuze kuzuzwe okunembile Indawo okuya kuyo okuphakelayo. Ukuze uqedele kangcono ukunemba okuqhubekayo kokuphakelayo nokuqinisekisa ukulinganisa kwesisindo se-multihead, i-hopper enkulu yokuphakela okuqhubekayo kanye nevalvu ezenzakalelayo egcwele yokuphakela kufanele kumiswe emgqonyeni wokuphakela. Kukhona inani eliphezulu lomkhawulo (recharge_terinated) kanye nenani eliphansi lomkhawulo (recharge_started) kumitha yokulawula.

Lapho isisindo senetha esikalini sifinyelela inani eliphansi lomkhawulo, isignali izothunyelwa ukuvula i-valve yokulayisha kabusha, i-valve yokulayisha kabusha izovulwa, izinto zokusetshenziswa endaweni yokugcina impahla zizokwehliselwa emgqonyeni wokulayisha ngokusho koxhumano oluguquguqukayo lwe-conductive. , futhi isisindo inetha esikalini siyokhula.
