Abstract

A liquid packaging machine produces liquid packaging bags by controlling a side seal roll, an end seal roll, a cut roll coordinately. These rolls are driven by servo-motors separately as a multi-axis servo mechanism. In this paper we propose a two steps velocity controller to produce bags of arbitrary size and a phase control system which determines the cut position on a film according to the seal position. The control system changes the rotary phase difference of two rolls by changing the velocity reference of the cut roll. Experimental results using a liquid packaging machine show the effectiveness of the proposed control system.
