Abstract
A method and apparatus for automatically screen printing on objects includes a first transfer mechanism having suction cups for swinging the objects from a supply station at which are located a plurality of the objects to a preregistering station at which is a preregistering device which rotates the objects into a predetermined orientation closely positioned to a reference position to which the object is printed. From the preregistering station, the objects are swung by a second oscillating transfer means to a third oscillatory transfer means which swings the preregistered objects to the printing station. Preferably, the objects are swung into a holding station wherein the objects are held between transfer movements by the respective second and third transfer means. At the printing station it is preferred that the objects be centered relative to the rotating chuck device by camming the objects if they are not co-axially mounted in the chuck device so as to align the spinning axis of the objects with the rotational axis of the chuck device. Grippers are swung into the printing station to remove the printed object and to convey the printed object to a discharge station.
