在生(sheng)(sheng)(sheng)產(chan)率高、生(sheng)(sheng)(sheng)產(chan)節拍短的大批量(liang)生(sheng)(sheng)(sheng)產(chan)條件下(xia),由(you)于要(yao)求上(shang)下(xia)料動(dong)作(zuo)迅速和頻繁,操作(zuo)工(gong)人(ren)的勞動(dong)強度(du)很(hen)大,所以實(shi)現(xian)上(shang)下(xia)料自動(dong)化對于減輕工(gong)人(ren)體力(li)勞動(dong)強度(du)、提高生(sheng)(sheng)(sheng)產(chan)率、實(shi)現(xian)多機(ji)床(chuang)管理和保證安(an)全生(sheng)(sheng)(sheng)產(chan)具(ju)有重要(yao)意義。理想(xiang)的上(shang)料裝置應該具(ju)備效率高、供料速度(du)快、工(gong)作(zuo)可靠、噪聲小、不損傷工(gong)件、結構緊湊(cou)、通用(yong)(yong)性(xing)好、使用(yong)(yong)壽命長、易(yi)維(wei)護(hu)修理和制造成本低廉等優(you)點。
