ABSTRACT:
An upstacker reject device includes a reciprocating plunger connected to a selectively oscillating shaft. A bellcrank is adjustably connected to a press ram and a rotatably mounted cylinder. A clutch is engaged to transfer rotary motion from the cylinder to the shaft. As the press ram travels downwardly, the cylinder and shaft are rotated, thereby causing the plunger to travel upwardly and engage an article carried by a transfer belt. A cylinder assembly and motion restriction cooperate with the clutch to insure that the plunger is retracted before the belt is advanced.
