Munyori: Smartweigh–Multihead Weighter
A multihead weigher muchina unoshandura kinetic simba kubva kune imwe nzira kuenda kune imwe. Kunyanya, multihead weigher isimba sensor inoshandura simba remagetsi (senge simba rekutsigira, shrinkage, kushanda nesimba kana torque) mumasaini emagetsi anogona kuyerwa nemazvo. Simba rekumanikidzika rechiratidzo che data rinoshanduka nesimba rekumanikidza rekuburitsa simba.
Kune matatu akakosha marudzi eakawanda mahead weigher anoenderana neinobuda data siginecha: hydraulic, pneumatic uye resistance strain gauge. Rudzi rwakajairika rwehuyeri hunoshandiswa mukugadzirwa kwemaindasitiri ndeye multihead weigher ine yakavakirwa-mukati dhizaini. Iyo yekupikisa strain gauge multihead weigher ine yakasimba simbi yemuviri muviri (kana "elastic yero chikamu") inogadzirisa yekudzivirira strain geji.
Imba yacho inowanzo gadzirwa nealuminium, kabhoni simbi kana simbi isina simbi ndiro, zvichiita kuti ive yakasimba asi yakanyanyisa ductile. Maitiro eiyo multihead weigher anokanganisa zvishoma kana chikero chikaiswa, asi chinodzokera kune chimiro chayo chepakutanga mukati, kunze kwekunge chiri mutoro. Kuti upindure zvirinani kune shanduko yechimiro chemuviri, iyo yekudzivirira strain gauge inoshandurawo chitarisiko chayo.
Izvi zvinokonzeresa shanduko yekupokana kweiyo resistance strain gage, iyo inogona kuyerwa nemazvo seanoshanda voltage shanduko. Nekuti shanduko dzakadai mukubuda dzine hukama nehuremu hwemambure akaburitswa, huremu hwemambure echinhu chacho hunogona kutariswa kubva kune yekushanda voltage shanduko. Chiyereso chine misoro yakawanda chinoshanda sei? Kuti upindure "Muyero wemusoro wepamusoro unoshanda sei?" unofanira kutanga wanzwisisa "Sei resistance gauge inoshanda sei?" A resistance strain gauge mudziyo unoyera nemazvo mafambiro emudziviriri kana simba raburitswa.
Iyo yakajairika yekudzivirira dhizaini gage ine yakanaka kwazvo waya mesh yefoiri, yakaiswa mune yegridi patani, zvichiita kuti waya inodzivirira ishanduke kana simba rekumanikidza rinoburitswa pamwe neaxis imwe. Kune marudzi akasiyana-siyana emageji ekupikisa kusarudza kubva: Linear resistance strain gauge: Mutsara wemagetsi wakabatana nechekuseri kwegeji yekupikisa inofananidzwa nechekumucheto kwegeji yekudzivirira. Izvi zvinoshandiswa kuyera nemazvo radial strain uye kubhenda dhiri.
Kucheka kupikisa majeji emagetsi: Mitsetse yemagetsi yakabatanidzwa kuseri kwezviyero zvekupikisa zvakaiswa kumativi ose maviri ekushanda kwekumanikidzika kwechimiro pane 45o orientation. Izvi zvinoshandiswa kuyera nemazvo kutema dhiri. Resistance strain gauges anowanzo shandiswa pamwe chete nenhamba huru yemajeji ekupikisa dhizaini kuvandudza kunyatsoita.
Imwe yedhijitari simba amplifier resistance strain gauge inonzi quarter bridge, maviri edigital power amplifier resistance strain gauges anonzi hafu bhiriji, uye mana edhijitari simba amplifier resistance strain gauges anonzi akazara zambuko. Resistance strain gage resistor transitions hazvina kufanana nekuremedza bhatiri rinochajika musimba rinotsigira. Iyo nhanho yekumanikidza inoita kuti inopikisa gauge ipfave uye kurebesa, ichisimudza resistor.
Simba rekusimbisa rinopfupisa kukora kweyero yekupikisa gauge uye inoderedza kushorwa. The resistance strain gauge inosungirirwa kumusana wakaonda (fixed bracket), iyo inokurumidza kusungirirwa kune weighing module, ichibvumira kupikisa strain gauge kuti inzwe simba rekumanikidzika remuyero wemultihead. Iyo resistor shanduko yakayerwa nenzira kwayo neimwechete inopokana strain gage idiki kwazvo, ingangoita 0.12.°.
Kunzwa kwemutoro wemutoro kunowedzera nehuwandu hwemajeji emagetsi anoburitswa. Nzira yakanaka yekushandura shanduko diki iyi kuita chimwe chinhu chinobatika ndeyekuvabatanidza seSmart kuyera mabhiriji. Mhando dzemajeji ekupikisa majeji Majeji ekupikisa anotarwa nenzira dzakasiyana, uye chokwadi chiri murudzi rwesimba rinoyerwa nemazvo.
Kubhenda kunetsa, kugera kurema, radial strain, torque uye kushanda nesimba zvese zvinoyerwa nemazvo uchishandisa yakasarudzika kurongeka kwemajeji ekupikisa. Iyo Smart weigh bhiriji redunhu yakashongedzerwa ina yakaenzana resistors uye inoshandisa inozivikanwa excitation inoshanda voltage, sezvakaratidzwa pazasi: 5 ndiyo inozivikanwa yakagadzikana inoshanda voltage uye VO inoyerwa nemazvo. Kana zvese zvinopikisa zviri pakati, zvinoreva kuti R1/R2R3/R4 uyezve VO i zero.
Kana pane shanduko mune imwe yemaitiro ekupikisa, pachava nekushanduka kweVO, iyo inogona kuyerwa zvakarurama uye inoratidzwa uchishandisa mutemo weOhm. Mutemo waOhm unosimbisa kuti huwandu hwemazuva ano (I, mu amperes) hunopfuura nemuitisi wemagetsi pakati pemapoinzi maviri hune hukama hwakanaka nemagetsi ekushanda (V) pakati pemapoinzi maviri. Resistor (R, yakanyatsoyerwa muohms) inounzwa setsanangudzo inoshanduka mumubatanidzwa uyu uye haina chekuita nekuyerera kwazvino.
Mutemo waOhm unoratidzwa muchimiro I = V/R. Kana yaiswa kune 4 mapepa mitsetse yeSmart weigh bhiriji simba redunhu, izvo zvinokonzeresa equations ndezvi: Mune multihead weigher, kuramba uku kunotsiviwa neregisheni yekupikisa mukutsiviwa kwesimba rekutsigira uye kuyerwa chaiko kwekuderera. Kana simba racho raburitswa kune yakayerwa rechargeable bhatiri, zvinopikisa mune yega yega yekupikisa gauge shanduko uye VO inoyerwa nemazvo.
Kubva pane inoguma data data, VO inogona kutsanangurwa zviri nyore uchishandisa iyo iri pamusoro system ye equations.
