Kudumpha kwa singano ndi kulukana mwachangu kwambiri

Pa makina oluka ozungulira, kupanga bwino kwambiri kumaphatikizapo kusuntha kwa singano mwachangu chifukwa cha kuchuluka kwa zakudya zoluka ndi makina.liwiro lozunguliraPa makina oluka nsalu, kusintha kwa makina pamphindi imodzi kwawonjezeka kawiri ndipo chiwerengero cha ma feeder chawonjezeka kakhumi ndi kawiri pazaka 25 zapitazi, kotero kuti njira zokwana 4000 pamphindi imodzi zitha kuluka pamakina ena wamba, pomwe pamakina ena othamanga kwambiri opanda zingwe.liwiro la tangentialSingano zitha kupitirira mamita 5 pa sekondi. Kuti tikwaniritse izi, kafukufuku ndi chitukuko chakhala chofunikira pakupanga makina, kamera ndi singano. Zigawo zopingasa za kamera zachepetsedwa pang'ono pomwe zingwe za singano ndi zingwe zachepetsedwa kukula kulikonse komwe kungatheke kuti tichepetse kuchuluka kwa kayendedwe ka singano pakati pa malo ochotsera ndi ogubuduza. 'Kudumpha kwa singano' ndi vuto lalikulu pakuluka makina othamanga kwambiri. Izi zimachitika chifukwa chakuti singano imayesedwa mwadzidzidzi ndi kugunda pamwamba pa kamera yokwera itatha kuthamanga kuchoka pamalo otsika kwambiri a kamera yosokera. Pakadali pano, kulephera kwa singano pamutu pake kungayambitse kugwedezeka mwamphamvu kwambiri kotero kuti kungasweke; komanso kamera yokwera imayamba kuphulika m'gawoli. Masingano omwe amadutsa m'gawo lophonya amakhudzidwa makamaka pamene matako awo amakhudza gawo lotsika kwambiri la kamera yokha komanso pa ngodya yakuthwa yomwe imawafulumizitsa kutsika mofulumira kwambiri. Kuti achepetse izi, kamera yosiyana nthawi zambiri imagwiritsidwa ntchito kutsogolera matako awa pa ngodya pang'onopang'ono. Ma profiles osalala a non-linear cam amathandiza kuchepetsa kugwedezeka kwa singano ndipo mphamvu ya braking imatheka pa matako mwa kuchepetsa kusiyana pakati pa stitch ndi up throw cams. Pachifukwa ichi, pa makina ena a payipi, up-throw cam imatha kusinthidwa mopingasa pamodzi ndi vertical-adjustable stitch cam. Reutlingen Institute of Technology yachita kafukufuku wambiri pa vutoli ndipo, chifukwa chake, kapangidwe katsopano ka latch singano yokhala ndi tsinde lozungulira, profile yosalala pang'ono, ndi mbedza yayifupi tsopano yapangidwa ndi Groz-Beckert ya makina oluka ozungulira othamanga kwambiri. Mawonekedwe a meander amathandiza kufalitsa impact shock isanafike pamutu wa singano, yomwe mawonekedwe ake amawongolera kukana kupsinjika, monga momwe imachitira low profile, pomwe latch yowoneka bwino imapangidwa kuti itsegule pang'onopang'ono komanso mokwanira pamalo otetezedwa opangidwa ndi kudula kawiri.

Zovala zapamtima zokhala ndi ntchito zapadera

Kupanga zinthu zatsopano pamakina/ukadaulo

Mapantihose ankapangidwa mwachizolowezi pogwiritsa ntchito makina oluka ozungulira. Makina oluka a RDPJ 6/2 a Karl Mayer adayambitsidwa mu 2002 ndipo amagwiritsidwa ntchito popanga ma tights osasokonekera, okhala ndi mawonekedwe a jacquard ndi ma pantyhose a ukonde wa nsomba. Makina oluka a MRPJ43/1 SU ndi MRPJ25/1 SU a jacquard tronic raschel ochokera ku Karl Mayer amatha kupanga ma pantihose okhala ndi zingwe ndi mapangidwe ofanana ndi relief. Kusintha kwina kwa makina kudapangidwa kuti kuwonjezere kugwira ntchito, kupanga bwino, komanso khalidwe la ma pantihose. Kuwongolera kusalala kwa zipangizo za pantihose kwakhala nkhani ya kafukufuku wina wa Matsumoto et al. [18,19,30,31]. Adapanga njira yoluka yoyesera yosakanikirana yopangidwa ndi makina awiri oyesera ozungulira. Zigawo ziwiri za ulusi wokhala ndi chivundikiro chimodzi zinalipo pa makina aliwonse ophimba. Ulusi wophimbidwa ndi chimodzi unapangidwa mwa kuyang'anira milingo yophimba ya 1500 twists pa mita (tpm) ndi 3000 tpm mu ulusi wa nayiloni ndi chiŵerengero chokoka cha 2 = 3000 tpm/1500 tpm pa ulusi wapakati wa polyurethane. Zitsanzo za pantyhose zinalukidwa pansi pa mkhalidwe wokhazikika. Kuwala kwakukulu mu pantyhose kunapezeka ndi mulingo wocheperako wophimba. Milingo yosiyanasiyana yophimba tpm m'madera osiyanasiyana a miyendo inagwiritsidwa ntchito popanga zitsanzo zinayi zosiyana za pantyhose. Zomwe zapezekazi zasonyeza kuti kusintha mulingo wophimba ulusi umodzi wophimbidwa m'magawo a miyendo kunakhudza kwambiri kukongola ndi kuyera kwa nsalu ya pantyhose, ndipo kuti makina osakanikirana amatha kukulitsa mawonekedwe awa.
