Bag-making machine control system research The bag-making machine control system is controls based on the labor machine the integration computer control system, controls machine the control software by the labor to complete the system bag process each kind of function coordination control, and substitutes the original mechanical major axis by the electronic axis, had guaranteed strictly each printing unit's synchronization, provides one kind for the bag-making machine based on the computer control integration solution. The bag-making machine is on the processed foods production line manufactures bag's processing equipment using the plastic film.

Bag-making machine's control system mainly includes: The main actuation electrical machinery servocontrol, the fixed-length positioning control system, the tensity control system, the temperature control system, to feed control system and the electro-optic correct an error the control system. At present, the most bag-making machine control system's host actuation electrical machinery servocontrol and the fixed-length positioning control system is a body, namely controls take the labor machine forms a three servocontrol as the control core, but the tensity, the electro-optic correct an error, the temperature and to feed control system independence in this three servocontrol. Each system independent types of control increased the bag-making machine coordination control difficulty mutually, also reduced the entire control system's reliability, to further enhance system's automated performance, must develop the new control plan.

In the system bag process, the thin film volume material launches continuously, and corrects an error through the electro-optic with the advanced gear to enter in continuously the folding formation installment. Thin film after folding formation, carries on the hauling and the localization by the fixed-length localization draw gear enters the heat-seal working procedure. Makes in the bag flow the heat-seal working procedure, is causes the laminated film heat-seal spot using the heating wire heating the heat-seal level to turn the plastic flow condition, draws support again cutting tool's

pressure, causes high and low two heat-seal material each other to fuse together in together, after the cooling, can maintain certain intensity, has leak-proof and so on good. The heat-seal good bag may according to need to carry on processings and so on punch and margin, finally completes the dinking die by the dinking die installment, makes the end product bag.

Bag-making machine's control system must complete the main servo electrical machinery and the feed bag hauling servo electrical machinery's motion control, this contained feed bag's fixed-length positioning control, the system must also complete the feed bag to correct an error, to feed, the tensity and the heat-seal temperature control. The control system controls take the labor machine as a core, carries on each control function the hardware expansion, controls machine the control software through the labor to improve each function conformity the system coordination control performance, forms a computer control system. In addition, the remote diagnosis technology applies in the bag-making machine can strengthen bag-making machine's maintainability.

The main servo electrical machinery's types of control are the speed control, the main electrical machinery leads the hot knife vertical motion through four pole organizations, through controls the main electrical machinery driver's speed to control hot knife's state of motion. The feed bag hauling servo electrical machinery's control is the position control, must realize the fixed-length localization hauling. These three servo electrical machinery's coordination control can guarantee the hauling and the heat-seal and the dinking die coordinated work. Puts the material and the feed bag to feed servo electrical machinery may unify with this three servo motor control forms a multiple spindle servo to actuate the control system together. The use may complete many servo electrical machinery's motion control based on the PC machine main line's multiple spindle movement controller, like this simplified the servo to actuate control system's hardware, favored each servo electrical machinery's coordination control. The movement controller controls machine the main line through the labor to carry on the communication with it, like this causes employing labor to control machine the control software then to monitor the movement controller, realizes to
