基于PLC标签打印控制系统的设计概要.docVIP

摘 要 标签打印，顾名思义就是打印标签。标签是指产品上的文字图形符号及一切的说明物。 随着市场经济的发展和商品的激烈竞争，标签已成为公平交易、商品竞争的一种重要形式。 所以本次设计主要为了实现更加方便快捷的控制标签打印的过程以及标签内容更易改的打印系统而设计。本次设计的主要思路为通过PLC控制俩部分来实现，第一部分通过PLC的输出控制交流接触的线圈来控制标签打印电机的运行，进行标签打印；第二部分，通过PLC的输出控制频器，在通过变频器对传送电机进行三段速的控制，最终实现设计。 通过最终测试，实现了以上的标签打印设计。 ABSTRACT Label printing, just as its name implies is to print label. The words on the label, the product is all graphic symbols and instructions. With the development of the market economy and the fierce competition of commodities, the label has become a fair trade, an important form of competition of the commodity. With the progress of science and technology rapid development, standards, standardized management, enterprises constantly improve, in all walks of life, about the quality of the label image, safe, efficient and accurate management of the demand is higher and higher! Specification label management has become all walks of life, one of the important contents of the various departments attach great importance to by more and more managers, so the label production and printing has become a part of the daily work, how effectively to produce high quality label will be a question of attention, especially in most of Chinas need to use the label, such as efficient management in professional printer support, under the premise, how to achieve high quality label on ordinary printer typesetting and printing, there is a common sense. So this design mainly in order to achieve more convenient and quick control label printing process and label printing system and design content are more likely to change. The design of the main ideas implemented by PLC control two parts, the first part through the output of the PLC control ac contactor coil to control the operation of label printing machine, label printing, The second part, through the output of the PLC control of frequency, in to three sections of transmitting motor by the frequency converter control, finally realizes the design. Through the final testing, an
