在(zai)生(sheng)產(chan)(chan)率高(gao)、生(sheng)產(chan)(chan)節拍(pai)短的大批量(liang)生(sheng)產(chan)(chan)條件下,由于要求上(shang)下料(liao)(liao)動(dong)作迅速(su)和頻繁,操作工(gong)(gong)人的勞動(dong)強度很(hen)大,所以實(shi)現(xian)上(shang)下料(liao)(liao)自動(dong)化對(dui)于減輕工(gong)(gong)人體力勞動(dong)強度、提高(gao)生(sheng)產(chan)(chan)率、實(shi)現(xian)多機床管理和保證(zheng)安(an)全生(sheng)產(chan)(chan)具有重要意義。理想的上(shang)料(liao)(liao)裝置應該具備效率高(gao)、供料(liao)(liao)速(su)度快、工(gong)(gong)作可靠、噪聲(sheng)小、不損傷工(gong)(gong)件、結構緊湊、通用(yong)性好、使用(yong)壽命長、易維(wei)護修理和制造成本低廉等(deng)優點。
