ABSTRACT:
A multi-station screen printer is provided with components which simplify maintenance, reduce repair and increase ease of use. The printer includes at least one printing head which defines a printing station, a screen holding device positioned thereunder for holding a screen, and at least one arm for carrying substrates positionable below the screen holding device. A flood bar and squeegee carriage is slideably mounted to the printing head and is shiftable by a telescoping cable which shifts the carriage between a print position wherein the squeegee is lowered to the screen and a non-print position wherein a flood bar is lowered near the screen. The arm for carrying platens is provided with a ball and socket system of registration which reliably positions the arm at each station and releases the arm therefrom after printing on the substrate. A carriage position sensing circuit utilizes a potentiometer to sense the translational position of the carriage and also utilizes control limit pots to provide dial-adjustment of stop points, thus eliminating limit switches and providing increased ease of use. Further, the printing head and also the screen holding device are pivotally mounted to the printer main frame between a lowered position maintained during normal press operation, and a raised position which is used to facilitate cleaning, maintenance, and setup.
