在(zai)生(sheng)(sheng)產(chan)率高(gao)、生(sheng)(sheng)產(chan)節拍短的(de)大(da)批(pi)量(liang)生(sheng)(sheng)產(chan)條件下,由于要(yao)求上下料(liao)動(dong)作迅速和頻繁,操作工(gong)(gong)人(ren)的(de)勞動(dong)強度很大(da),所以實現上下料(liao)自(zi)動(dong)化(hua)對于減輕工(gong)(gong)人(ren)體力勞動(dong)強度、提高(gao)生(sheng)(sheng)產(chan)率、實現多機床(chuang)管理(li)和保證安(an)全生(sheng)(sheng)產(chan)具有重(zhong)要(yao)意(yi)義。理(li)想的(de)上料(liao)裝置應(ying)該具備效率高(gao)、供(gong)料(liao)速度快、工(gong)(gong)作可靠、噪聲小、不損傷(shang)工(gong)(gong)件、結構(gou)緊湊、通用(yong)性好、使用(yong)壽命長、易(yi)維護(hu)修理(li)和制(zhi)造成本低廉等優點(dian)。
