A New Control Scheme for Sealing System in Continuous Motion Form/Fill/Seal Packaging Machines

Abstract:

It has been proved through the extensive study of continuous Form/Fill/Seal packaging machine that the outlook and final quality of the formed bags are largely dependent on the accurate synchronisation of vertical and horizontal sealing subsystems. In this paper, we first investigate synchronisation problem existed in the sealing system of traditional continuous F/F/S packaging machine which is mainly due to the mechanical non-constant transmission system used in the current continuous F/F/S packaging machine. A new control scheme is then proposed to address this problem in which the driving of the horizontal and vertical sealing has been made into independent but connected subsystems and controlled by separate control modules. We discuss the mathematical model and physical design in which the mechanical transmission part is discarded therefore simplifies the whole design of the machine. The new control scheme has been testified in several industrial applications with excellent performance result.
