37、了满足我国啤酒行业日益扩大生产规模的需求和啤酒现代化灌装机械高速灌装的要求，国内各啤酒生产厂家都在积极寻求或改造本单位的啤酒灌装生产设备，使其成为具有良好的使用性能，先进的技术水平及高生产效率、运行稳妥可靠、维护成本低的啤酒现代化灌装机。2. 啤酒灌装、压盖机工作原理和控制部分构成液体灌装机按灌装原理可分为常压灌装机、压力灌装机和真空灌装机。啤酒灌装、压盖机采用压力灌装方法，是在高于大气压力下进行灌装，贮液缸内的压力高于瓶中的压力，啤酒液体靠压差流入瓶内。目前国内外实现灌装工艺路线基本上是：利用回转酒缸产生的旋转运动，使安放在酒缸槽位上的空瓶通过机械机构将固定在酒缸上部的欲抽真空阀打开，对已封

38、好的瓶子进行抽真空处理，拨转外操作阀杆，打开气阀，对瓶内充填CO2气体，抽真空凸轮继续打开真空阀，将瓶内空气与CO2混合气体抽出，气阀再次打开，对瓶内充填CO2气体，灌装阀内的液阀在瓶内压力接近背压气体压力时打开，酒液顺瓶壁注入瓶内，通过气动或电动控制灌装阀实现啤酒的灌装。当今国际先进的啤酒灌装、压盖机的控制系统主要由光电开关位置检测部分、走瓶带、酒缸转速的变频调速部分、主控由可编程控制器、触摸屏等组成。灌装、压盖机的机械结构装置与PLC可编程控制、变频无级调速、人机界面等现代自动控制技术手段完整的结合，形成机电一体化。3. 控制部分改造方案国内很多啤酒厂家现使用的灌装、压盖机的控制系统的自动

39、化程度参差不齐；所有手动按钮和工艺开关都设置在一个操作箱的面板上，PLC控制器大都为日本OMRON公司或三菱公司的早期产品，设备连锁控制、保护设置少，加之啤酒灌装的现场环境恶劣，潮湿度大，使开关等接触触点锈蚀严重，系统的信号检测部分故障率较高，造成设备控制系统运行的可靠性低，设备正常运行周期短等现象。以实际改造的丹东鸭绿江啤酒有限公司的灌装、压盖机的控制系统为例，介绍改造方法，阐明改造这类设备的控制思想和思路；根据现场的实际工艺条件，重新编写了PLC的运行程序。针对啤酒灌装、压盖机控制系统的实际状况，并根据现场的实际工艺条件，重新设计了设备的PLC控制系统。这种改造方法和思路同样可以应用与其他

40、液体介质灌装设备的改造。3.1系统硬件配置使用日本三菱公司的FX2N128MRPLC替换原系统使用的2台OMRON公司的C60PPLC，原系统的PLC由于是老型号产品，和计算机联机需要配置特殊的通讯转换器，系统需要增加外部I/O输入点时，扩展模块备件较难寻。FX2N128MRPLC是集成128点I/O的箱体式控制器，具有运算速度快，指令丰富、性能价格比高、联机编程简单、扩展方便等优点，是三菱FX系列中功能最强的小型控制器。(1) 采用三菱公司的900系列的97OGOT人机触摸屏替换原系统使用的面板按钮并监控显示设备的运行工作参数。970GOTHMI为高亮度的16色显，通过汇流连接和FX2N12

41、8MRPLC的CPU直接连接，实现快速回应。具有许多维护功能，如列表式编辑功能、梯形图监控(故障查找)功能、系统监控功能等用来查找故障和维护PLC系统。(2) 灌装、压盖机的变频器在改造中没有更换，现场检测信号的手段仍然采用开关式检测，因检测开关长期工作在湿度很大的场合，因此选择电容式的接近开关，根据PLCI/O端子的接线方式，选择PNP型的接近开关。3.2.系统程序设计PLC控制器的程序设计重点和核心是围绕着酒缸的旋转速度控制和酒缸上60个瓶位相关位置的检测移位、破瓶、空瓶瓶位相关位置的检测移位和相关灌装阀等的控制。其中的瓶位移位检测程序中，采用了三菱PLC位左移指令。瓶位移位检测，采用PL

42、C位左移指令，这条指令是整个子控制程序的核心之一，主电机和瓶位检测开关同步检测移动的酒瓶，主电机每转一周，正好对应酒缸转过一个瓶位，PLC内部单元内对应这60个瓶位的单元为M500M559,单元个数用第一个字母K设置为K60，每次变化一位用第二个字母K设置为K1，M50反应了瓶位的空、缺位置，并将检测到的这个位置以电机转速的频率移位下去，在内部相应的单元内置1或0，控制相应的阀门和搅拌瓶盖的电机的开与停。系统在连续检测90个空瓶位后,停止搅拌瓶盖的电机的运行,检测瓶位的个数可以根据用户的要求任意设定。出瓶位检测。回转酒缸通过压力往瓶内背压装酒的过程中，空瓶在背压后,可能由于瓶子本身裂纹等原因导

43、致突然爆瓶,这就需要检测出爆瓶瓶子的位置,在这个瓶位的位置进行打开吹扫电磁阀,喷出压缩空气,将瓶位上的碎瓶片吹离位置,在连续吹扫几个瓶位后,在打开喷射电磁阀,喷射出高压水注,在对破瓶位置周围瓶位连续喷射几个瓶位。破瓶检测和瓶位检测开关同步检测移动的破瓶，主电机每转一周，正好对应酒缸转过一个瓶位，PLC内部单元内对应这20个破瓶位的单元为M600M619,单元个数用第一个字母K设置为K20,每次变化一位用第二个字母K设置为KI,M52反应了破瓶的位置，并将检测到的这个位置以电机转速的频率移位下去，在内部相应的单元内置1或0,控制相应的喷射和吹扫电磁阀开与停。连续喷射和吹扫电磁阀的开听、停时间可以

44、根据工艺要求任意设定。系统自动化运行可靠的保障就是控制进出瓶盖的同步跟踪,既准确检测电机转速检测开关、破瓶检测开关和进瓶检测开关三个条件。970GOT人机触摸屏操作终端机的软件采用三菱公司的GTWORKS软件包，其中GTDesigner是一个用与整个GOT9000系列的绘图套装软件。该软件包操作简单,事先可在个人计算机上组态并仿真调试,完毕后下载至人机操作终端机。同时,因为人机界面又具有触摸屏的作用,将常用的开关设在显示屏上,方便操作。还可并以增加一些功能,如设置报警信息等。4改造后控制系统功能系统正常运行时,机器为自动控制,根据进出瓶带上瓶的满缺,按设定速度或慢速运行,进瓶档瓶,无瓶不下盖,

45、爆瓶自动冲洗,灌装位置自动背压,下盖输盖系统的自动开停和安全保护等动作的协调联锁。原来所有按钮的操作改造后都在触摸屏上进行。5控制系统检测状态的监控功能进瓶检测开关和破瓶检测开关通过检测每个压瓶部分上面的小铁片的位置,产生光电脉冲输出，再有PLC采集，由于每个压瓶部分上面的小铁片的位置是活动的,在机器运行一段时间后,压瓶部分上面的小铁片和检测开关的位置发生位移，造成检测开关误判断，如没瓶判断为有瓶，爆瓶漏检、误检等造成输出失误，使PLC产生误动作，造成如背压、爆瓶吹、洗、瓶盖搅拌系统控制失灵等故障现象。在改造前的日常生产过程中，碰到这种现象时，操作工只能将各个功能开关或按扭打到手动控制档位，使

46、机器设备工作在无监控状态下，机器失去自动控制功能。造成了很大的生产原料如气、水、酒的浪费。只能在生产的间歇，才能由维修钳工和电工根据检测开关上的小发光二极管的亮和灭通过调整位移距离只有58mm的检测开关的安装位置，来修正检测开关和小铁片的间隙。这种检测手段非常落后，调整后的效果反应致后，不能及时反应调整结果。针对这种检测状况，结合改造后的灌装、压盖机控制系统的配置，新增了这部分检测功能，并集成在人机触摸屏中，完成瓶位检测。在人机触摸屏的界面分页显示屏上，可以分别时关、搅拌电机等电磁阀的开关状态都以不同颜色来显示，非常直观。增加这套系统功能的是为保证灌状压盖机的自动化控制系统正常运行而专门设计的。6结束语改造后的控制系统大大地简化了复杂的机械结构，经现场运行情况和控制效果检验，系统的自动化程度达到了设计要求，大大减少了操作人员的劳动强度，使啤酒灌状的日产量比过去提高30%以上，故障率大大减低。体现了现代设备的自动控制技术。是在消化、吸收当今工业控制的先进技术的基础上加以创新、研制而成的目前国内技术最先进的灌装控制系统。
