在生(sheng)產(chan)(chan)率高(gao)、生(sheng)產(chan)(chan)節拍短的大(da)批量生(sheng)產(chan)(chan)條件下,由于(yu)要求上(shang)(shang)下料(liao)動(dong)(dong)作(zuo)迅速(su)和(he)頻繁(fan),操作(zuo)工(gong)(gong)人的勞動(dong)(dong)強度很大(da),所以(yi)實(shi)現上(shang)(shang)下料(liao)自動(dong)(dong)化對于(yu)減輕工(gong)(gong)人體(ti)力(li)勞動(dong)(dong)強度、提高(gao)生(sheng)產(chan)(chan)率、實(shi)現多機(ji)床(chuang)管理和(he)保證安全生(sheng)產(chan)(chan)具有重(zhong)要意義。理想的上(shang)(shang)料(liao)裝置應該具備效率高(gao)、供料(liao)速(su)度快、工(gong)(gong)作(zuo)可靠、噪聲(sheng)小、不損傷工(gong)(gong)件、結(jie)構緊(jin)湊(cou)、通用(yong)性好、使用(yong)壽(shou)命長(chang)、易(yi)維護修理和(he)制造成本低廉等優點。
