自動(dong)(dong)封口(kou)(kou)包(bao)(bao)裝(zhuang)設備是通(tong)過光(guang)感(gan)傳感(gan)器來實(shi)(shi)現(xian)(xian)(xian)光(guang)標定(ding)(ding)位(wei)，然后(hou)通(tong)過光(guang)控系(xi)(xi)統(tong)對(dui)包(bao)(bao)裝(zhuang)系(xi)(xi)統(tong)進(jin)行同步控制(zhi)，以此(ci)完成自動(dong)(dong)封口(kou)(kou)包(bao)(bao)裝(zhuang)。用(yong)(yong)來實(shi)(shi)現(xian)(xian)(xian)定(ding)(ding)位(wei)控制(zhi)的(de)(de)光(guang)電技術(shu)可提供一種用(yong)(yong)固(gu)定(ding)(ding)標志點結合線(xian)性(xing)或旋轉運動(dong)(dong)部件(jian)(jian)來實(shi)(shi)現(xian)(xian)(xian)簡單可重復(fu)運動(dong)(dong)的(de)(de)方法。它利用(yong)(yong)了與(yu)一對(dui)光(guang)電管并聯工作(zuo)的(de)(de)一個功率運放的(de)(de)快速響應時間。由此(ci)實(shi)(shi)現(xian)(xian)(xian)的(de)(de)一種元件(jian)(jian)數量(liang)很少的(de)(de)系(xi)(xi)統(tong)，能在明(ming)確規定(ding)(ding)的(de)(de)工作(zuo)環境下，具有很高的(de)(de)可靠性(xing)、準確性(xing)以及可重復(fu)性(xing)。

    在線連卷制袋機在自動(dong)包(bao)裝過程中(zhong)，由(you)于商標印刷誤(wu)(wu)差，薄膜變形不(bu)一(yi)，牽引輥打滑，送(song)紙(zhi)，拉(la)紙(zhi)，中(zhong)封(feng)(feng)(feng)，橫(heng)封(feng)(feng)(feng)各部(bu)分(fen)速度的差異，橫(heng)封(feng)(feng)(feng)切(qie)斷(duan)位置可能(neng)偏離規定(ding)部(bu)位，甚至因誤(wu)(wu)差積(ji)累而(er)切(qie)到(dao)商標圖(tu)案上(shang)。為此，先進的包(bao)裝機(ji)都(dou)配有(you)光(guang)電跟蹤(zong)自動(dong)控(kong)制系統(tong)，以控(kong)制封(feng)(feng)(feng)切(qie)位置使之保(bao)(bao)持(chi)正確，保(bao)(bao)證每次都(dou)在定(ding)位標記確定(ding)的位置處封(feng)(feng)(feng)接切(qie)斷(duan)，不(bu)致于封(feng)(feng)(feng)切(qie)到(dao)圖(tu)案上(shang)。這就是(shi)光(guang)感(gan)傳感(gan)器在自動(dong)封(feng)(feng)(feng)口控(kong)制系統(tong)的主要應用。
