APPARATUS FOR CONTROLLING MOTIONS AT A GLASSWARE LEHR LOADER AND METHOD OF CONTROLLING MOTIONS OF A LOADER BAR IN THE LOADER

摘要

In an individual section (IS) glassware forming system that includes a lehr loader (24) having a loader bar (30) and electric actuators (32, 34, 36) for controlling motion at the loader bar along forward, sideshift and lift axes independently of each other to load glassware from a cross conveyor (22) across a transfer plate (40) onto a lehr conveyor (42), apparatus for controlling motion at the loader bar includes an operator station (64) for entry of a plurality of control parameters (FIGS. 5 and 6) that relate to physical characteristics of the glassware, cross conveyor, transfer plate, lehr and loader bar. The operator station includes prestored programming for automatically translating the control parameters entered by the operator into motion profiles (FIGS. 4A to 4C) for each of the three axes, with each of the profiles comprising a data set of motion data versus time data. An electronic controller (38) is coupled to the electric actuators for controlling motions at the loader bar along the three axes as a function of associated sets of motion data versus time data.
