PLC在设计啤酒次品回收机中的应用

Application of PLC in the Design of Beer Substandard Products Reclaiming Machine

针对当前啤酒次品回收的自动化程度低的现状,设计了全自动的啤酒次品回收机。该机电气控制部分包括主回路和控制回路,主回路由2台电机提供动力;控制回路由过程控制、液位显示与控制和清洗控制回路等构成。本设计采用可编程控制器(PLC)来实现该机过程控制,并运用顺序设计法设计出比较完善的电气控制梯形图,提高了自动化程度。该设计装置若投入生产,可以改变目前国内啤酒行业靠传统手工回收次品的现状,自动完成啤酒生产中的次品回收。

In view of the backward beer substandard products reclaiming status at present, a full-automated beer substandards products reclaiming machine has been designed.The electric control part of the machine include main circuit and controlling circuit, two motors supplies power to main circuit, and controlling circuit is comprised of process-control, the loop of fluid level and LCD displaying and cleaning system controlling etc. This design achieves procedure control by the use of PLC and figures out comparatively complete electrical control chart by sequential design method, which has improved the automated level of the machine. If such design was put into practice, present domestic beer substandard products reclaiming status （manual recaliming） would be replaced by automated beer substandard products reclaiming.
