在生(sheng)產(chan)率高、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)下料(liao)(liao)動(dong)作(zuo)(zuo)迅(xun)速(su)(su)和(he)頻(pin)繁,操(cao)作(zuo)(zuo)工(gong)(gong)(gong)人的(de)勞動(dong)強度很大,所以實(shi)現上(shang)下料(liao)(liao)自動(dong)化對于減輕工(gong)(gong)(gong)人體力勞動(dong)強度、提高生(sheng)產(chan)率、實(shi)現多(duo)機床管理(li)和(he)保證安全生(sheng)產(chan)具有重要意義。理(li)想的(de)上(shang)料(liao)(liao)裝置應(ying)該具備(bei)效率高、供料(liao)(liao)速(su)(su)度快、工(gong)(gong)(gong)作(zuo)(zuo)可靠、噪聲小、不損傷工(gong)(gong)(gong)件、結(jie)構緊湊、通用(yong)性好(hao)、使(shi)用(yong)壽命(ming)長、易維護修理(li)和(he)制造成本(ben)低(di)廉(lian)等優點。
