ABSTRACT:
Each station has a push-off unit which transfers glass articles produced at such station onto a common outfeed conveyor. Each push-off unit comprises a cylinder-piston unit mounted for swinging movement on a vertical swing shaft, the piston thereof carrying a push-off arm. The push-off arm extends and engages the articles to be transferred, the cylinder swings towards the belt transferring the article, and the push-off arm retracts and the cylinder swings back. The push-off units of the plural stations are activated sequentially, in correspondence to the sequence in which glass gobs are fed into the respective machine stations. Plural electric motors are provided, one per station, and the swing motion of the push-off unit is generated by the respective electric motor. The rotation of each electric motor is controllable, by open- or closed-loop control, independently of the other electric motors. The operator selects the sequence in which the electric motors are to be activated. A common or shared desired-rpm voltage is applied to all electric motors, sequentially. The electric motors drive the push-off units through respective crank and rocker mechanisms.
