Design of the Solid Products Automatic Packaging Systems Based on PLC

In this paper,the automatic control system is designed,in which the weighing instruments,PLC,screw conveyor,slot machines,slow and stop transportation motor is used to finish the functions such as the chemical products' automatic weighing,feeding,bagging,sealing and transmission,so that the packing of two production lines can be completed automatically.The delivering and weighing of the product in the packing is realized by the independent weighing instrument and bagging,transportation agencies in the system,so it can reduce the artificial control.At the transport and sewing part,it increases alarm device,which can ensure the accuracy of the packaging technology.
