Hlola ukukala

A hlola ingumshini othomathikhi noma wesandla wokuhlola isisindo sempahla efakiwe. Ngokuvamile kutholakala ekugcineni kwe-a inqubo yokukhiqiza futhi isetshenziselwa ukuqinisekisa ukuthi isisindo sepakethe yempahla ingaphansi kwemikhawulo ebekiwe. Noma amaphakethe ezingaphandle kokubekezelelwa zithathwa ngaphandle kolayini ngokuzenzakalelayo.

I-Checkweigher ingaba nesisindo esingaphezu kwezinto ezingama-500 ngomzuzu (ngokuya ngosayizi we-carton nezidingo zokunemba). Ama-Checkweighers angasetshenziswa nawo metal detector futhi Imishini ye-X-ray ukunika amandla ezinye izimfanelo zephakethe okufanele zihlolwe futhi zisebenze ngokufanele.

Umshini ojwayelekile

Ukuhlola okuzenzakalelayo kufaka uchungechunge lwe amabhande okuhambisa. Lama-Checkweighers ayaziwa nangokuthi amabhande asindayo, esikalini sokunyakaza, isikali sokuhambisa, isikali esisebenzayo, nezikali ezikumugqa. Kuzicelo ze-filler, zaziwa ngokuthi hlola isikali. Imvamisa, kukhona amabhande amathathu noma imibhede ye-chain:

• Ibhande elingaxutshwe nalutho elingashintsha ijubane lephakheji futhi ulinyuse noma lihlehle ngejubane elidingekayo lokukala isisindo. I-infeed nayo kwesinye isikhathi isetshenziswa njenge-indexer, ebeka igebe phakathi kwemikhiqizo ibanga elifanele lokukala. Kwesinye isikhathi kunamabhande noma amaketanga akhethekile ukubeka umkhiqizo ngesisindo.

• Ibhande lesisindo. Lokhu ngokuvamile kufakwe ku-transducer yesisindo okuvame ukuba yiseli yokulayisha umthwalo noma i-servo-esele (eyaziwa nangokuthi yi-Force-esele), noma kwesinye isikhathi eyaziwa ngokuthi ugongolo lokuhlukanisa. Eminye imishini emidala ingahle imise ibhande lesisindo embhedeni ngaphambi kokuthatha isisindo. Lokhu kungakhawulela isivinini somugqa nokudlula.

• Ibhande lokwenqaba elihlinzeka ngendlela yokususa iphakethe elingabekezeleleki kulayini wokuhambisa. Ukwenqatshwa kungahluka ngohlelo lokusebenza. Ezinye zidinga i-air-amplifier ukushaya imikhiqizo emincane ibhande, kepha izinhlelo ezisindayo zidinga i-actuator eqondile noma esabalalayo. Eminye imikhiqizo entekenteke iyenqatshwa “ngokubeka” umbhede ukuze umkhiqizo ushibilikise ngobumnene emgqonyeni noma kwesinye isithuthi.

Ngokwesikali sokuqonda okuphezulu, iseli lomthwalo elisebenzisa ukubuyiselwa kwamandla kagesi (i-EMFR) kufanelekile. Lolu hlobo lohlelo lukhokhisa i-coil efundisayo, iqaqa kahle umbhede osindayo enkanjini ye-electromagnetic. Lapho isisindo sengezwa, ukunyakaza kwento ebilayo ngaleyo coil kubangela ukuguquguquka kwekhoyili yamanje okuhambelana nesisindo sento. Obunye ubuchwepheshe obusetshenzisiwe buhlanganisa amasheya wokulinganisa namangqamuzana omthwalo we-vibrating.

Kuyinto ejwayelekile ukuthi ikhompyutha eyakhelwe ngaphakathi ithathe ukufundwa okuningi kwesisindo kusuka ku-transducer esikhathini lapho iphakethe lisembhedeni wesisindo ukuqinisekisa ukufundwa kwesisindo okunembile.

Ukulinganisa kubalulekile. Isilinganiso selebhu, esivame ukuba segumbini elingalodwa licindezelwe nge-nitrogen eyomile (icindezelwe emazingeni olwandle) singakala into ngaphakathi kokuhlanganisa noma ikhiphe 100th wegram, kepha umfutho womoya oqhubekayo uyinto. Lokhu kuqondile lapho kungekho ukunyakaza, kepha ekuhambeni kukhona into engabonakali-umsindo ovela ekuhambeni kwebhande elinesisindo, ukudlidliza, ukufakelwa komoya noma esiqandisini okungenza kungaphelele. I-Torque kuseli yomthwalo ibangela ukufundwa okungafani.

Isihloli esisebenza ngamandla, esishukumisayo sithatha amasampula, bese siwahlaziya ukuze sakhe isisindo esinembile esikhathini esithile. Ezimweni eziningi, kune-trigger evela kudivayisi ye-optical (noma ye-ultrasonic) ukukhombisa ukudlula kwephakeji. Lapho umlilo usubasile, kuba nokubambezeleka okusethwe ukuvumela iphakethe ukuthi lihambise “endaweni emnandi” (maphakathi) yombhede onesisindo ukusampula isisindo. Isisindo sisampuliwe isikhathi esithile. Uma esinye salezi zikhathi singalungile, isisindo siyoba esingalungile. Kubukeka sengathi ayikho indlela yesayensi yokubikezela lezi zikhathi. Amanye amasistimu anesici se- "graphing" sokwenza lokhu, kepha imvamisa iyindlela yokwenza esebenza kahle kakhulu.

• Isikhumuli esenqenayo ukunika amandla amaphakheji angaphandle kokukhuthazeka asuswe kokugeleza okujwayelekile ngenkathi kusahamba endaweni yokuhamba. Indlela yokwenqaba ingaba yinye yezinhlobo eziningana. Phakathi kwalokhu kukhona i-pneumatic pusher elula ukusunduza eceleni kwepakethe elinqatshiwe kusuka ebhandeni, ingalo eguqukayo ukuze ikhukhulele eceleni kwendlela nebhande elilahlayo elehlisa noma eliphakamise ukuphambukisa ipakethe ngokuqondile. Umhloli wokuhlola ojwayelekile uvame ukuba nomgqomo wokuqoqa amaphakethe angaphandle kokubekezelela. Kwesinye isikhathi la ma-bins anikezwa ngesikhiya, ukuvimbela ukuthi ngaphandle kwezinto ezibekiwe kudliwe emuva ngebhande lokuhambisa.

Izindlela zokubekezelela

Kunezinhlobo eziningana ukubekezelelana izindlela:

• Uhlelo lwendabuko "lwesisindo esincane" lapho izinsimbi ezingaphansi kwesisindo esinqunyiwe ziyenqatshwa. Imvamisa isisindo esiphansi isisindo esiphrintwa kuphakethe noma ileveli yesisindo eyeqile leyo yokuvumela ukwehla kwesisindo ngemuva kokukhiqizwa njengokuhwamuka kwempahla enomswakama. Izinkampani ezinkulu kakhulu ezidayisa impahla ngobuningi zigunyaze ukuthi noma yimuphi umkhiqizo othunyelwe kuwo uhlolwe isisindo esinembile ukuze ikhasimende lithembele ukuthi lithola inani lomkhiqizo elikhokhele wona. Lawa ma-wholesaler akhokhisa imali enkulu ngamaphakheji agcwaliswe ngokungafanele.

• The Uhlelo Olukhulu Lwesisindo SaseYurophu okulandela imithetho emithathu ebekiwe eyaziwa ngokuthi yi "Packers Rules"
• Okunye okushicilelwe Amazinga kanye nemigomo efana neNist Handbook 133

Data Collection

Kukhona futhi isidingo ngaphansi kwe-European A average Weight System yokuthi idatha eqoqwe ama-Checkweighers ifakwa kungobo yomlando futhi iyatholakala ukuthi ihlolwe. Iningi lamanje lokuhlola amasheke lifakwe ngamachweba ezokuxhumana ukunika amandla isisindo sangempela sepakethe nedatha ethathwe ukuthi ilayishwe kwikhompyuter eningi. Le datha ingaphinde isetshenziselwe imininingwane yokuphatha evumela izinqubo ukuba zilungiswe kahle futhi ukwenziwa komsebenzi kubhekwe.

Ama-Checkweighers afakwe ukuxhumana okusheshayo okufana namachweba we-Ethernet ayakwazi ukuzihlanganisa ngokwamaqembu ukuze iqembu lezintambo zokukhiqiza ezikhiqiza imikhiqizo efanayo lingabhekwa njengolayini owodwa wokukhiqiza ngezinjongo zokulawulwa kwesisindo. Isibonelo, umugqa osebenza ngesisindo esiphansi ongalinganiswa ngomunye osebenza ngesisindo esiphakeme esiphakeme kangangokuba ukuhlanganiswa kwemigqa emibili kusazohambisana nemithetho.

Enye indlela wukuhlela i-checkweigher ukuhlola amabhendi we-tolerances ehlukene wesisindo. Isibonelo, isisindo esiphelele esingu-100 amagremu ± 15 amagremu. Lokhu kusho ukuthi umkhiqizo ungaba nesisindo esingu-85 g - 115 g. Kodwa-ke, kusobala ukuthi uma ukhiqiza amaphakethe ayi-10,000 ngosuku, futhi iningi lamaphakethe wakho angama-110 g, ulahlekelwa ngumkhiqizo ongu-100 kg. Uma uzama ukugijima usondele ku-85 g, ungahle ube nezinga lokwenqaba eliphakeme.

ISIBONELO: I-Checkweigher yenzelwe ukukhombisa izindawo ezi-5 ezinesixazululo 1 g:

1. Ngaphansi Kwenqatshwa…. umkhiqizo unesisindo esingu-84.9 g noma ngaphansi
2. Ngaphansi kukaKULUNGILE …… .. umkhiqizo unesisindo esingu-85 g, kepha ungaphansi kuka-95 g
3. Kuvumelekile ……… .. umkhiqizo unesisindo esingu-96 g, kepha ungaphansi kuka-105 g
4. Ngaphezu KOKULUNGILE ……… umkhiqizo unesisindo esingu-105 g, nangaphansi kuka-114 g
5. Ukwenqatshwa… .. umkhiqizo unesisindo esingaphezu komkhawulo ongu-115 g

Ngo-isisindo esenziwe isheke njengendawo yokuhlola indawo, ukuqoqwa kwedatha phezu kwamanethiwekhi, kanye nezibalo zasendaweni, kungakhombisa isidingo sokubheka izilungiselelo kumishini ekhuphukayo ukulawula ukugeleza okungcono kokufaka. Kwezinye izimo isikali esisebenzayo sithumela isibonakaliso kufiller, ngokwesibonelo, ngesikhathi sangempela, silawula ukugeleza kwangempela emgqonyeni, ikhegi, isikhwama, njll. Ezimweni eziningi i-Checkweigher inesihlahla esikhanyayo esinamalambu ahlukile ukukhombisa ukuhluka kwesisindo sendawo yomkhiqizo ngamunye.

Le datha ingasetshenziselwa ukunquma ukuthi ngabe kukhona inkinga ngokugcwaliswa, noma ukufakwa, komshini. Umuntu ohlola angathumela isignali emshinini ukukhulisa noma ukunciphisa inani elifakwa kwiphakheji. Lokhu kungaholela ekubuyiselweni kwemali okuhlotshaniswa ne-checkweigher ngoba abakhiqizi bazokwazi ukulawula inani lokupha. Bheka i-caseweigher case study echaza ukonga inyama yenkomo nokupakisha.

Ukucatshangelwa kwesicelo

Ijubane nokunemba okungatholakala nge-Checkweigher kuthonywa okulandelayo:

Izicelo

Isikali esisebenzayo yimishini eshukumisayo engahle yakhelwe ukwenza izinkulungwane zemisebenzi. Amanye asetshenziswa njengama-caseweighers alula ekugcineni komugqa wokuhambisa ukuze aqiniseke ukuthi umkhiqizo ophelele wephakheji ophelele ungaphakathi kwesisindo sawo.

Ukunyakaza umhambisi I-Checkweigher ingasetjenziselwa ukuthola izingcezu zekhithi ezingekho, njengephakheji leselula elilahlekile Ama-Checkweighers asetshenziswa ngokujwayelekile kwuchungechunge olungenisayo lokuhambisa, kanye nokufaka kuqala kokufaka umhambisi iketanga esitshalweni sezinkukhu. Inyoni iyasindwa uma ingena kwi umhambisi, lapho-ke ngemuva kokucubungula nokugeza ekugcineni, ikhompyutha inethiwekhi iyakwazi ukubona ukuthi inyoni idonsa kakhulu noma cha, okuthi njengoba icutshungulwa, izokhishwa, okwenza inyoni ibe ngaphansi kwesisindo sayo.

Ijubane elikhulu umhambisi isikali singasetshenziswa ukuguqula ukuhamba kancane, noma iphimbo lemikhiqizo kulayini ngokusheshisa, noma ukunciphisa ijubane lomkhiqizo ukushintsha ibanga phakathi kwamaphakethe ngaphambi kokufinyelela isivinini esihlukile sokuya emshinini wokuhambisa ophakamisa amaphakethe amaningi ebhokisini. “Iphimbo” yisilinganiso somkhiqizo njengoba wehla kulayini wokuhambisa kusuka onqenqemeni oluholayo uye emaphethelweni aholayo.

I-checkweigher ingasetshenziselwa ukubala amaphakethe, nesisindo (ingqikithi) yesisindo samabhokisi angena ku-pallet ezothunyelwa, kufaka phakathi amandla okufunda isisindo sephakethe ngalinye nobukhulu be-cubic. Ikhompyutha yesilawuli ingaphrinta ilebula lokuthumela kanye nelebuli yekhodi ye-bar ukukhomba isisindo, ubukhulu be-cubic, ikheli lokuthumela ngomkhumbi, nenye idatha yomazisi womshini ngokuthunyelwa komkhiqizo. Umuntu ohlolwayo ohlola ukuthunyelwa angafunda ilebula ngeskena sekhodi yebha, futhi anqume ukuthi ngabe ukuthunyelwa kunjengoba kwakunjalo ngaphambi kokuthi othwala izinto zokuthwala akuthole esikhumulweni sokulayisha somkhumbi, futhi anqume ukuthi ibhokisi alikho yini, noma ngabe kukhona okuphangiwe noma ephukile ekuhambeni.

Ama-Checkweighers asetshenziselwa futhi Ukuphathwa kwekhwalithi. Isibonelo, izinto ezingavuthiwe zokwakha umshini zithwala isisindo ngaphambi kokuqala inqubo, futhi ngemuva kwenqubo, umhloli wekhwalithi ulindele ukuthi inani elithile lensimbi lisuswe lapho kuqeda ukwenziwa. Amabhele aqediwe ayabhekwa, futhi ukuthwala ngokweqile- noma isisindo somzimba kuyenqatshwa ukuze kuhlolwe umzimba. Lokhu kuyinzuzo kumhloli, ngoba angaba nokuzethemba okukhulu ukuthi abangenqatshiwe bangakwazi ukubekezelelwa ngemishini. Ukusetshenziswa okujwayelekile kukwehlisa izikelezi zepulasitiki ezinjenokuthi ibhodlela elisetshenziselwa ukufaka iphakethe lokuhlanza lihlangabezana nezidingo zephakeji eliphelile.

Ukuphathwa kwekhwalithi angasebenzisa isheke Ukuhlolwa okunempilo ukuqinisekisa impahla eseqedile usebenzisa okujwayelekile Izindlela zokuhlola ukuthola izingcezu ezingekho kumkhiqizo “osuqediwe”, njengamafutha avela ethangeni, noma iroli elahlekile ngaphakathi endlini.

Ama-Checkweighers angakhiwa ngemitshina yensimbi, imishini ye-x-ray, ukutholwa kwe-open-flap, ama-bar-code scanner, ama-holographic scaners, izinzwa zokushisa, abahloli bemibono, izikulufo zesikhathi ukusetha isikhathi nezikhala phakathi komkhiqizo, amasango wokukhomba kanye namapayipi e-concentrator ukukhuphula umkhiqizo ungene endaweni ekhethiwe kumthuthi. Umuntu ohlola ukunyakaza kwezimboni angahlunga imikhiqizo kusuka engxenyeni yegremu iye kumakhilogremu amaningi, amaningi. Kumayunithi esiNgisi, ngabe lokhu kusuka ngaphansi kuka-100th we-ounce kuye kufinyelela kuma-500 lbs noma ngaphezulu. Ama-checkweigher akhethekile angalinganisa izindiza zezentengiselwano, futhi aze athole ne-center-of-gravity yazo.

Ama-Checkweighers angasebenza ngejubane eliphakeme kakhulu, acubungule imikhiqizo enesisindo sezingxenyana zegremu ngaphezulu kwe-100m / m (amamitha ngomzuzu) nezinto ezifana nemithi yokwelapha kanye nezikhwama ezingama-200 lb zomkhiqizo ngaphezulu kuka-100fpm (izinyawo ngomzuzu). Zingakhiwa ngezimo nobukhulu obuningi, zilenga ophahleni, zikhuliswe kuma-mezzanines, eziqhutshwa kuhhavini noma eziqandisini. Indlela yabo yokudlulisa ingaba ngamabhanti ezimboni, amabhande asezingeni eliphansi, amaketanga afana namaketanga amabhayisikili (kodwa amancane kakhulu), noma amabhande amaketanga ahlanganisiwe anoma yibuphi ububanzi. Bangaba namabhande wamaketanga enziwe ngezinto ezikhethekile, ama-polymers ahlukene, izinsimbi, njll.

Ama-Checkweigher asetshenziswa ezindlini zokuhlanza, ezindaweni ezomile, ezindaweni ezimanzi, akhiqiza izinqolobane, ukucubungula ukudla, ukucubungula izidakamizwa, njll. Ama-Checkweigher acaciswa uhlobo lwemvelo, futhi uhlobo lokuhlanza luzosetshenziswa. Imvamisa, isheke lokuhlola umkhiqizo lenziwe ngensimbi emnene, futhi ezohlanzwa ngamakhemikhali anokhahlo, njenge-bleach, kuzokwenziwa ngazo zonke izingxenye zensimbi engagqwali, ngisho namaseli e-Load. Le mishini ibhalwe ukuthi “washdown okugcwele”, futhi kumele ibe nayo yonke ingxenye nengxenye yayo ebekiwe ukuze iphile endaweni yokuhlanza.

Ama-Checkweighers asetshenziswa kwezinye izinhlelo zokusebenza isikhathi eside kakhulu- seminyaka engama-24/7 unyaka wonke. Ngokuvamile, imigqa yokuhambisa ayimiswa ngaphandle kokuthi kunesidingo sokulungiswa, noma kunendawo yokumisa eziphuthumayo, ibizwa nge-E-stop. Ama-Checkweighers asebenza emigqeni ephezulu yokudluliswa kobuningi bawo angaba nezinto eziningi ezikhethekile ekwakhiweni kwawo ukuqinisekisa ukuthi uma kwenzeka kumiswa i-E, wonke amandla aya kuzo zonke izithuthi asuswe kuze kube yilapho i-E-stop isuliwe futhi isetwa kabusha.
