A Study on the Key Technologies of a Kind of Automatic Packaging System

In order to improve the productivity of the filing form materials continuously and automatically packaged line, the control methods for the manipulator and the mechanism which has the capacity of weight self-measuring and auto–filling to the packaged material were studied. The manipulator is a pneumatic control system, it is consists of three pneumatic cylinder circuits to implement the horizontal movements, vertical movements and the activities of picking up or putting down the materials on line. The material to be picked up by manipulator was weighed and displayed by a single chip microcomputer. The general control function of the system was carried out by a PLC unit. The structure changeable type of simulating human being intelligence control methods resulting in the real observing at the objective changes were studied and implemented to achieve the plant high in positioning accuracy and fast in response speed. The experiments were realized and the results showed that the working period time is less than 5.8s,the weight variation measured by single chip microcomputer is not more than 2 grams in 300 grams.
