Abstract

With the traditional processing technology of concrete compared advantages of large-scale intelligent PC component automatic production line has high processing efficiency, full automatic control, high technology level, advanced equipment, fewer workers to operate, caused by human factors error is small, and the subsequent expansion of strong。The production line can realize automatic, intelligent and systematic。 From raw material processing, processing a reinforcement net,PC cycle production, maintenance and storage, and has during the various aspects of the work of coherent coupling and very strong, coordinate system work well, to complete the high quality large precast concrete production。

With the development of the housing industry, the precast concrete component has become the direction and trend of the development of the industrialization of the Hyundai Residence。PC component auto maintenance equipment of three-dimensional become key equipment of the PC component factory prefabrication and automated production lines, its factory space using rate is high, and is easy to realize the automatic management of the member access, as well as parameters to control the maintenance temperature control system, to realize the automatic control of concrete component maintenance process to a key role。Automatic maintenance equipment and PC components of the automatic production line, can greatly improve the production efficiency, reduce labor costs, and better realize the PC components of the factory prefabricated production。

The automatic stereo maintenance equipment includes three parts, which are the stacking machine, the steel structure solid maintenance kiln, and the automatic control system。 Among them, the crane is the key lifting, handling equipment。 This paper discusses the structure, principle and characteristics of the control system of the stacking crane in the PC component production line, and introduces the design of the control system of the crane。 According to the access characteristics of PC component production line, the control system diagram is designed。 And using PLC control program ladder diagram。 

KEY WORDS:   PC component production line；stacker；control system；PLC
