Control System Design of Ice Factory Packing Line
Packaging production line of an ice factory includes main line, sideway machine, feeding machine, packaging machine, blanking machine and drawing tray machine etc., Control system may fulfill the action of segregation, feeding movement and packaging, for the more, the speed of sideway conveyor can be adjusted online according to that of main line, and working velocity of related mechanism will change in the meanwhile. There are two kinds of operation mode, they are online mode and offline mode, and a TextDisplay is used as interface, S7-221PLC is used to detect various working speed, and coordination operation of equipments is achieved by PLC sending out pulses of different frequency (PTO). Hardware and software design methods are introduced and problems met during the adjusting process are discussed also.
