以前在醫藥生產方面藥粉的加料仍然需要人工加料，隨著國內生產技術的發展成熟國內自20世紀80年代開始規模性應用膠囊充填機以來，其上料方式經過了幾個過程：從原來人工爬梯倒料到輸送帶輸送，從桶式提升到正壓輸送，從真空輸送到自動真空輸送，另外還有跨層式氣控自重輸送，其發展表現出上料方式隨著時代發展而取得的進步。全自動上料機的(de)(de)結構膠(jiao)囊充(chong)填(tian)機(ji)(ji)所配置上(shang)料(liao)(liao)方式為(wei)自(zi)動上(shang)料(liao)(liao)。全自(zi)動上(shang)料(liao)(liao)機(ji)(ji)的(de)(de)原理(li)：自(zi)動真(zhen)空(kong)上(shang)料(liao)(liao)機(ji)(ji)工作(zuo)時，主機(ji)(ji)工作(zuo)腔室(shi)在(zai) 0.03 MPa負壓作(zuo)用下產(chan)生(sheng)高速流動的(de)(de)氣流，并通過(guo)輸送管將周轉桶內(nei)物(wu)料(liao)(liao)吸入(ru)(ru)(ru)主機(ji)(ji)工作(zuo)腔室(shi)內(nei)，之(zhi)后吸入(ru)(ru)(ru)的(de)(de)物(wu)料(liao)(liao)利用自(zi)重成螺旋(xuan)狀落入(ru)(ru)(ru)膠(jiao)囊充(chong)填(tian)機(ji)(ji)的(de)(de)料(liao)(liao)斗內(nei)。而在(zai)真(zhen)空(kong)氣源與(yu)物(wu)料(liao)(liao)通路上(shang)置有進口濾(lv)(lv)布(bu)進行(xing)潔凈過(guo)濾(lv)(lv)，并伴隨著(zhu)上(shang)料(liao)(liao)過(guo)程的(de)(de)同時，附(fu)著(zhu)在(zai)濾(lv)(lv)布(bu)上(shang)的(de)(de)微粉(fen)將利用機(ji)(ji)械自(zi)動抖動予以清理(li)，以防止真(zhen)空(kong)通路受堵(du)。
