摘要:PLC在自动包装机上的使用,使得控制简洁,其对恶劣条件的适应性、可靠性、配置的灵活性等,使得其中该领域得到十分广泛的运用。现代自动包装机在工业生产中,对包装过程的自动化和精确性要求越来越高,如何快速精确的包装好产品是一个很重要的问题。包装的快速性表现在控制的自动化和持续性上,自动化要求选用更少的控制开关来达到控制的要求,持续性要求进料的连续,设计储料仓可以大大提高包装的持续性。面粉的混合重量直接关系其产品合格与否,精确性就要求对面粉的特性设置称重,根据其易受空气中水分影响附着在面粉包装机内部,每次包装前进行皮重测试,合格才可以进行下一步骤。报警系统与PLC相结合,可以有效解决故障,快速进行故障维护。

Abstract:Use of PLC in the automatic packing machine, making control simple, its adaptability, reliability, flexibility of configuration of the harsh conditions, which are very widely used in the field. Modern automatic packaging machine for industrial production, packaging automation and accuracy requirements of increasingly high, how fast and accurate packing of products is a very important issue. Packaging of fast performance in automation and control on a sustainable, automated selection requires less control switch to meet the requirement of control, sustainability requires continuous feed design storage silos can greatly improve the sustainability of packaging. Flour mix weight qualified or not directly related to its products, accuracy requirements set on the characteristics of flour weight, according to their vulnerable to moisture in the air attached inside the flour packing machine, before each package tare weight tests, can only pass on to the next step.  Alarm system combined with the PLC, can effectively resolve the fault, fault maintenance quickly.

自动包装机增加测量皮重环节,大大提高了包装机的精准性,报警系统的设计不但可以提醒操作人员及时切断故障,还可以根据报警系统中的故障指示灯对相对应的环节进行维修,大大减少维修的时间。本设计已通过实验室三菱公司的FX2N系列可编程控制软件的调试,达到了最初的设计要求,就有较高的可靠性而且控制简单。但设计中由于设备条件的限制,还有待进一步的验证。
