ABSTRACT:
A tube transfer assembly for a tube printer includes a rotatable mandrel wheel which successively moves the tubes to be printed to different stations of the tube printer; a plurality of mandrels mounted along the circumferential periphery of the mandrel wheel for holding the tubes thereon; a rotatable star wheel assembly including a plurality of pockets for successively supplying the tubes to a position at the free end of the mandrel at the 11:00 position of the mandrel wheel; a guide disc rotatable with the star wheel and having a plurality of circular apertures positioned about the periphery thereof in alignment with the pockets; a first pusher rod which successively pushes one end of each tube within one of the apertures at a first rotatable position of the star wheel to correctly configure such end of the tube in a circular configuration; a second pusher rod simultaneously moveable with the first pusher rod which successively pushes each tube onto the mandrel at the subsequent 11:00 position of the mandrel wheel; a plurality of sleeves slidably mounted on the mandrels; a backstop normally engaged with the sleeves at all but the 3:00 position of the mandrel wheel to prevent sliding movement of the sleeves on the respective mandrels and disengaged from the sleeve then positioned at the 3:00 position on the mandrel to permit sliding movement thereof; and a tube discharge assembly including a pusher take-off engaged with the sleeve at the 3:00 position of the mandrel wheel to slidably move the sleeve on the respective mandrel thereat so as to remove the tube on the mandrel.
