Abstract
An improved simple and low cost tamping system for a printed sheets compiling system directly driven by partial rotation of a reversible stepper drive motor driving a single molded plastic tamper drive unit. That tamper drive unit integrally includes a rigid radially extending portion rotatably driven by the drive motor, an elongate flexible member portion driven from one end by the rigid rotatable portion, and a tamper at the opposite end of the elongate flexible member. The elongate flexible member is slidably mounted in a fixed guides system to smoothly transition from an initial arcuate configuration to a final linear configuration to convert reversing partial rotational movement of the stepper drive motor into the desired substantially linear reciprocal sheet edge tamping movement of the tamper. Simply by rotating the stepper motor by a greater amount of rotation the desired initial position of the tamper can be reset when the sheet size or the desired stacking position of the sheets to be tamped is changed.
