Basebenza njani oomatshini bokupakisha beperile yomgubo othe nkqo? Oomatshini bokupakisha betywina bezalisa ngokuthe nkqo basetyenziswa phantse kuwo onke amashishini namhlanje, kwaye ngesizathu esihle: bayindlela yokupakisha ekhawulezayo, eyongayo egcina indawo exabisekileyo yomgangatho wefektri. Nokuba umtsha kumatshini wokupakisha okanye sele unolwazi ngeenkqubo ezininzi, unomdla wokuba zisebenza njani na. Kule nqaku, ndiza kwazisa indlela umatshini wokuzalisa i-pearl powder ochanekileyo unokuguqula umqulu wefilimu yokupakisha kwisikhwama esigqityiweyo kwi-shelf.

Umatshini wokupakisha ome nkqo owenziwe lula uqala ngomqulu omkhulu wefilimu, uwufake kwingxowa, ugcwalise ingxowa ngemveliso, kwaye uyitywine ngokuthe nkqo, ngesantya esiphezulu seengxowa ezingama-300 ngomzuzu. Kodwa kukho okungakumbi. 1. Ukuzikhulula ngokuzenzekela Ukupakishwa okuthe nkqo kusebenzisa umaleko omnye wemathiriyeli yefilim (edla ngokubizwa ngokuba yiwebhu) eqengqwa kumbindi.

Ubude obuqhubekayo bezinto zokupakisha kuthiwa yiwebhu yefilimu. Izinto eziphathekayo zinokuhluka kwi-polyethylene, i-cellophane laminates, i-foil laminates kunye ne-laminates yephepha. Beka ifilimu kwindibano ye-spindle ngasemva komatshini.

Xa umatshini wokupakisha usebenza, ifilimu idla ngokutsalwa kumqulu ngumqhubi wefilimu, obekwe kwicala letyhubhu ephambi komatshini. Le ndlela yokuthumela ngenqanawa yeyona isetyenziswa kakhulu. Kweminye imizekelo, imihlathi yokutywina ngokwayo ibamba ifilimu kwaye iyikhuphe phantsi, ivumele ukuba ihanjiswe ngepakethe ngaphandle kwesidingo sebhanti.

Ivili lokukhulula eliqhutywa ngemoto elinokuzikhethela linokufakelwa ukuqhuba ifilimu ukunceda ekuqhubeni izihambisi zefilimu ezimbini. Olu khetho luphucula inkqubo yokukhulula, ngakumbi ukuba ifilimu inzima. 2. Uxinzelelo lwefilimu Ngexesha lenkqubo yokukhulula, ifilimu ikhutshwe kwi-roll kwaye idlule ingalo ejikelezayo, eyingalo yepivot ye-counterweight ebekwe ngasemva komatshini wokupakisha.

Iingalo zifakwe ngokulandelelana kwee-roller. Ngexesha lokuthuthwa kwefilimu, ingalo ihla inyuka ukuze igcine ifilimu iphantsi koxinzelelo. Oku kuqinisekisa ukuba ifilimu ayihexanga ngapha nangapha njengoko ihamba.

3. Ukuprinta ngokuzikhethela Ukuba ifilimu ifakiwe, emva kokuba ifilimu idlule kwi-skipper yefilimu, iya kudlula kwiyunithi yokushicilela. Umshicileli unokuba ngumshicileli we-thermal okanye umshicileli we-inkjet. Umshicileli ubeka umhla/ikhowudi efunekayo kwifilimu, okanye ingasetyenziselwa ukubeka amanqaku obhaliso, iigrafiki okanye iilogo kwifilimu.

4. Ukulandelela ifilimu kunye nokubekwa emva kokuba ifilimu idlule phantsi kweprinta, iya kudlula kwiso lekhamera yobhaliso. I-photo-eye yokubhalisa ibona amanqaku okubhalisa kwifilimu eprintiweyo kwaye ilawula ibhanti lokutsalela phantsi ukuze uqhagamshelane nefilimu kwi-tube yokwenza. Gcina ifilimu kwindawo echanekileyo ngokulungelelanisa amehlo esithombe ukuze ifilimu inqunywe kwindawo efanelekileyo.

Emva koko, ifilimu idlula kwi-sensor yokulandelela ifilimu, efumanisa indawo yefilimu njengoko ihamba ngomatshini wokupakisha. Ukuba inzwa ibona ukuba umda wefilimu uyaphambuka kwindawo yayo eqhelekileyo, uvelisa umqondiso wokuhambisa i-actuator. Oku kubangela ukuba yonke inqwelo yefilimu ihambe iye kwelinye icala okanye kwelinye njengoko kufuneka ukubuyisela imiphetho yefilimu kwindawo echanekileyo.

5. Ukwenziwa kwengxowa Ukusuka apha ifilimu ingena kwindibano ye-tube yokubumba. Xa ithwala igxalaba (ikhola) yombhobho wokwenza, igoqwe phezu kombhobho wokwenza ukuze isiphelo sibe ubude befilimu enemiphetho emibini yangaphandle yefilimu edibanisana. Esi sisiqalo senkqubo yokwenza ingxowa.

Umbhobho owenziweyo unokusetwa kwi-lap seal okanye i-fin seal. I-lap seal igubungela imiphetho emibini yangaphandle yenwebu ukuze yenze itywina elisicaba, ngelixa i-fin seal idibanisa nengaphakathi leencamini ezimbini ezingaphandle zenwebu ukwenza itywina eliphuma njengephiko. Iitywina zeLap zithathwa ngokuba zithandeka ngakumbi kwaye zisebenzisa imathiriyeli encinci kunezotywino.

I-encoder ye-rotary ibekwe kufuphi negxalaba (i-flange) ye-tube eyenziwe. Ifilimu eshukumayo edibana nevili leencoder iyayiqhuba. Intshukumo nganye ivelisa i-pulse kwaye iyidlulisele kwi-PLC (Programmable Logic Controller).

Ubude bebhegi bumiselwe ngokwamanani kwiscreen seHMI (Human Machine Interface), kwaye nje ukuba olu seto lufikelelwe, uthutho lwefilimu luyayeka (Kwimishini eshukumayo engapheliyo kuphela. Oomatshini abashukumayo abaqhubekayo abamisi.) Ifilimu itsalwa phantsi ngegiya ezimbini. iimotor, ii-motors zeGear ziqhuba amabhanti okutsalela phantsi okukhuhlana kumacala omabini etyhubhu eyenza.

Ukuba uyanqweneleka, ibhanti lokutsalela phantsi elisebenzisa ukufunxa ngevacuum ukuqinisa ifilim yokupakisha linokusetyenziswa endaweni yebhanti lokukhuhlana. Iibhanti zefriction zicetyiswa ngokubanzi kwiimveliso ezinothuli kuba zinxiba ngaphantsi. 6. Ukuzaliswa kwengxowa kunye nokutywinwa Ngoku ifilimu iya kumisa ngokufutshane (kwi-packer ye-intermittent motion packer) ukwenzela ukuba isikhwama esibunjiweyo sifumane isitywina sayo esithe nkqo.

Isitywina esishushu esithe nkqo siqhubela phambili kwaye senza unxibelelwano kunye nokugqithela ngokuthe nkqo kwifilimu, idibanisa iileya zefilimu kunye. Kwisixhobo sokupakisha esiqhubekayo, indlela yokutywina ngokuthe nkqo isoloko inxibelelana nefilimu, ngoko ke ifilimu ayifuni kuyeka ukuze ifumane umthungo wayo othe nkqo. Okulandelayo, iseti yemihlathi eshushu yokutywina ethe tyaba ibotshelelwa kunye ukuze yenze itywina eliphezulu lengxowa enye kunye netywina elisezantsi lelinye.

Kumatshini wokupakisha ibhetshi, ifilimu iyayeka kwaye imihlathi ishukuma kwisenzo sokuvula kunye nokuvala ukufumana itywina elithe tye. Kumatshini wokupakisha oqhubekayo, imihlathi ngokwayo inokushukunyiswa phezulu naphantsi, okanye ngokuvula nokuvala izindululo zokutywina ifilimu. Abanye oomatshini abashukumayo abaqhubekayo bade babe neeseti ezimbini zemihlathi etywiniweyo ukwenzela ukwanda kwesantya.

I-Ultrasonic lukhetho lweenkqubo "zokutywinwa okubandayo", ezisetyenziswa ngokuqhelekileyo kumashishini aneemveliso ezinobushushu okanye obumdaka. Ukutywinwa kwe-Ultrasonic kusebenzisa ii-vibrations ukwenza ukungqubuzana kwinqanaba le-molecular, elivelisa ukushisa kuphela kwiindawo eziphakathi kwe-membrane layers. Ngelixa uvala imihlathi yokutywinwa, imveliso eza kupakishwa ithotywe ukusuka phakathi komngxuma owenziwe ityhubhu kwaye izaliswe kwingxowa.

Izixhobo zePearl powder, ezifana ne-multi-head scale okanye i-screw-type i-pearl powder machine, inoxanduva lokulinganisa ngokuchanekileyo kunye nokukhulula ubuninzi obucacileyo bemveliso ukuba ithontsizwe kwingxowa nganye. Le mishini yepearl powder ayiyona inxalenye eqhelekileyo yomatshini wokupakisha kwaye kufuneka ithengwe ngaphezu komatshini ngokwawo. Uninzi lwamashishini ludibanisa umatshini wepearl powder kunye nomatshini wokupakisha.

7. Ukukhulula isikhwama Emva kokubeka imveliso kwisikhwama, imela ebukhali kumhlathi wokutywina ukushisa ihamba phambili kwaye inqumle isikhwama. Imihlathi iyavuleka kwaye ingxowa epakishiweyo iyawa. Esi sisiphelo somjikelo kumatshini wokupakisha othe nkqo.

Kuxhomekeka kuhlobo lomatshini kunye nebhegi, izixhobo zokupakisha zinokwenza ama-30 ukuya kuma-300 ale mijikelo ngomzuzu. Iingxowa ezigqityiweyo zinokothulwa kwizikhongozeli okanye kwiimpahla zokuthutha kwaye zithuthwe ukuya kwisixhobo sokugqibela esifana ne-checkweighers, oomatshini be-X-ray, izixhobo zokupakisha iibhokisi okanye izixhobo zokupakisha iibhokisi.
