Malinga ndi kafukufuku wa Instititut für Druckmaschinen und Druckverfahren (IDD) wa ku University of Damstadt ku Germany, zotsatira za labotale zikusonyeza kuti mzere wodulira ndi manja umafuna anthu awiri kuti amalize ntchito yonse yodulira, ndipo pafupifupi 80% ya nthawi imagwiritsidwa ntchito ponyamula pepala kuchokera pa pallet kupita ku chonyamulira. Kenako, chifukwa chogwira ntchito ndi manja m'magulu, pepalalo limakhala lolimba, kotero njira yowonjezera yogwirira ntchito ndi pepala imafunika. Njirayi imafuna nthawi inayake kuti isanthule pepalalo. Kuphatikiza apo, nthawi yogwirira ntchito ndi pepala imakhudzidwa ndi zinthu zosiyanasiyana monga momwe pepala lilili, kulemera kwa pepala, ndi mtundu wa pepala. Kuphatikiza apo, thanzi la ogwira ntchito limayesedwa bwino. Malinga ndi tsiku la ntchito la maola 8, 80% ya nthawi imagwiritsidwa ntchito pogwira ntchito, ndipo maola 6 a tsiku ndi ntchito yamanja yolemera. Ngati mtundu wa pepala ndi waukulu, mphamvu ya ntchito idzakhala yokwera kwambiri.
Powerengedwa malinga ndi liwiro la makina osindikizira pa liwiro la mapepala 12,000 pa ola limodzi (dziwani kuti makina osindikizira a mafakitale osindikizira apakhomo amagwira ntchito 7X24), liwiro logwira ntchito la chingwe chodulira ndi manja ndi pafupifupi mapepala 10000-15000 pa ola limodzi. Mwanjira ina, ogwira ntchito awiri aluso amafunika kugwira ntchito mosalekeza kuti agwirizane ndi liwiro losindikiza la makina osindikizira. Chifukwa chake, mafakitale osindikizira apakhomo nthawi zambiri amagwiritsa ntchito makina odulira mapepala okhala ndi antchito ambiri, amphamvu kwambiri, komanso nthawi yayitali kuti akwaniritse zosowa za ntchito yosindikiza. Izi zipangitsa kuti ntchito zambiri ziwonongedwe komanso kuwonongeka kwa ogwira ntchito.
Podziwa vutoli, gulu la opanga mapulani la Guowang linayamba kukonza magulu aukadaulo mu 2013 ndipo linakhazikitsa cholinga cha momwe lingagonjetsere 80% ya nthawi yogwiritsira ntchito. Chifukwa liwiro la chodulira mapepala limakhala lokhazikika, ngakhale chodulira mapepala chapamwamba kwambiri pamsika ndi nthawi 45 pamphindi. Koma momwe mungachotsere 80% ya nthawi yogwiritsira ntchito kuli ndi zambiri zoti muchite. Kampaniyo imayika mzere wodulira wamtsogolowu m'magawo atatu:
1: momwe mungatulutsire pepalalo bwino kuchokera mu mulu wa pepala
Chachiwiri: Tumizani pepala lochotsedwa kwa wodula mapepala
Chachitatu: Ikani pepala lodulidwa bwino pa phala.
Ubwino wa mzere wopangira uwu ndi wakuti 80% ya nthawi yoyendera ya wodula mapepala yatsala pang'ono kutha, m'malo mwake, wogwiritsa ntchitoyo amayang'ana kwambiri kudula. Njira yodulira mapepala ndi yosavuta komanso yothandiza, liwiro lawonjezeka ndi nthawi 4-6, ndipo mphamvu yopangira yafika pa mapepala 60,000 pa ola limodzi. Malinga ndi makina osindikizira a offset omwe ali ndi liwiro la mapepala 12,000 pa ola limodzi, mzere umodzi pa munthu aliyense ukhoza kukwaniritsa ntchito ya makina osindikizira anayi a offset.
Poyerekeza ndi mphamvu yopangira mapepala 10,000 pa ola limodzi yomwe anthu awiri am'mbuyomu ankatha kupanga, mzerewu wapanga zinthu zambiri komanso zodzipangira zokha!
Tsatanetsatane wa njira yodulira mzere:
Mzere wonse wodulira kumbuyo wodzipangira wokha wagawidwa m'magawo atatu: chosankha mapepala chanzeru chokha, chodulira mapepala chofulumira kwambiri, ndi makina otulutsira mapepala okha. Ntchito zonse zitha kuchitidwa ndi munthu m'modzi pa sikirini yokhudza ya chodulira mapepala.
Choyamba, pogwiritsa ntchito chodulira mapepala pakati, malinga ndi kapangidwe ka malo ogwirira ntchito, chonyamulira mapepala ndi chonyamulira mapepala zitha kugawidwa kumanzere ndi kumanja nthawi imodzi kapena padera. Wogwiritsa ntchito amangofunika kukankhira chodulira mapepala kumbali ya chonyamulira mapepala ndi trolley ya hydraulic, kenako nkubwerera ku makina odulira mapepala, kukanikiza batani lonyamula mapepala, ndipo chotola mapepala chidzayamba kugwira ntchito. Choyamba, gwiritsani ntchito mutu wopondereza mpweya kuti mukanikize pepala kuchokera pamwamba pa chonyamulira mapepala kuti mupewe kuti chonyamulira mapepala chisagwedezeke panthawi yotola mapepala. Kenako nsanja yokhala ndi chopukutira cha rabara chozungulira mbali imodzi imasunga lamba wopingasa pa ngodya yopendekeka pang'ono ndikutsika pang'ono musanasunthire ku ngodya ya mulu wa pepala, kenako imatsikira kutalika kwa pepala komwe kompyuta imayika. Diso la photoelectric limatha kuwongolera kutalika kwake molondola. Kenako pita patsogolo pang'onopang'ono mpaka litakhudza mulu wa pepala. Chozungulira cha rabara chimatha kulekanitsa chipolopolo cha pepala mmwamba popanda kuwonongeka, kenako n’kuika nsanja yonse ya nsanjayo mu chipolopolo cha pepala pafupifupi 1/4 pa liwiro lachilengedwe lozungulira, kenako chopondera cha pneumatic chidzagwira chipolopolo cha pepala chomwe chiyenera kuchotsedwa. Tulutsani mutu wokakamiza womwe unakanikiza chipolopolo chonse cha pepala kutsogolo. Nsanjayo imapindanso mu mulu wonse wa pepala mofulumira kwambiri. Kenako nsanjayo imapita pang’onopang’ono kumbuyo kwa chodulira pepala mpaka itatsamira kwathunthu mbali ya tebulo logwirira ntchito kumbuyo kwa chodulira pepala. Panthawiyi, chodulira pepala chimatseka chodulira pepala ndipo chipolopolo chakumbuyo chimagwa chokha, ndipo chodulira pepala chimakankhira chipolopolo cha pepala pa nsanjayo. Lowani kumbuyo kwa chodulira pepala, chipolopolocho chimakwera, kenako chodulira pepala chimakankhira pepalalo kutsogolo malinga ndi pulogalamu yomwe yakhazikitsidwa, yomwe ndi yosavuta kwa wogwiritsa ntchito. Kenako chodulira pepalacho chimayamba kugwira ntchito. Wantchitoyo amazungulira pepalalo katatu mosavuta patebulo logwirira ntchito la air-cushion, amadula mbali zonse zinayi za mulu wa pepala bwino, ndikulikankhira ku nsanja yotulutsira mapepala yokonzedwa. Chotsitsa mapepala chidzasuntha chokha mulu wa mapepala. Kutsitsa pa phala. Kudula kamodzi kokha kumatha. Chodulira mapepala chikagwira ntchito, chotola mapepala chimagwira ntchito nthawi yomweyo. Mukatulutsa pepala loti lidulidwe, dikirani kuti pepalalo lidulidwe kenako mukalikankhirenso mu chodulira mapepala. Ntchito yobwezera.
Ngati mukuganiza kuti kufotokozerako ndi kwakutali kwambiri, onani vidiyo iyi:
