【Abstract】: In view of the shortcomings of manual sealing and manual sizing of the test bag, such as long time, low efficiency and poor reliability, the specific production process, control requirements and control components were analyzed, and the control scheme was selected to determine PLC control. The best control scheme, the connection between PLC and servo system and PLC and HMI communication connection, provide reference for further specific control implementation, software and hardware selection and programming, for subsequent test bag sealing and automatic glue automation. The realization laid the foundation.

0 ?引言
試卷印制是一個復雜的技術過程,除了要保證傳統的印刷質量外,更重要的是在整個生產過程中的安全、保密以及試卷的時效性[1]。由于試卷產品的多變性和多樣性,導致對試卷袋密封和施膠工作長期停留在手工作業上,整個試卷的生產效率不高。而且未實現對試卷內容的保密,試卷印制企業需要對能接觸到試卷內容印、裝、封各環節工人進行大量時間的入闈管理[2]。傳統的手工生產越來越難以滿足社會考試的需求,因此,急需研發試卷袋密封等關鍵技術以及集成創新形成的自動化生產設備,來提高企業試卷的保密性和生產效率。隨著PLC(可編程邏輯控制器)的出現[3],運用PLC來實現在試卷袋密封及自動施膠流程的控制,將實現試卷袋生產自動化,減少試卷印制企業員入闈數量,提高試卷生產效率和可靠性。……
