在生(sheng)產(chan)率高(gao)、生(sheng)產(chan)節拍短的(de)大批(pi)量(liang)生(sheng)產(chan)條件下,由于要求上(shang)(shang)下料(liao)動(dong)作(zuo)迅速和頻繁,操作(zuo)工(gong)(gong)(gong)人的(de)勞動(dong)強度(du)很大,所(suo)以實現(xian)上(shang)(shang)下料(liao)自動(dong)化對于減(jian)輕(qing)工(gong)(gong)(gong)人體力(li)勞動(dong)強度(du)、提高(gao)生(sheng)產(chan)率、實現(xian)多機(ji)床管理和保證安全生(sheng)產(chan)具(ju)有重要意義。理想的(de)上(shang)(shang)料(liao)裝置應該具(ju)備效(xiao)率高(gao)、供料(liao)速度(du)快、工(gong)(gong)(gong)作(zuo)可靠、噪聲小、不(bu)損傷工(gong)(gong)(gong)件、結構緊湊、通(tong)用(yong)性(xing)好、使(shi)用(yong)壽命長、易維護修理和制造成本(ben)低廉等優點。
