ABSTRACT:
A stacking-unstacking machine for bread pans and the like includes an elevator having pan support means thereon for carrying stacked pans to or away from a stacking-unstacking station, guide means being provided properly to align the pans for the stacking or unstacking operations, and particularly the latter. The pan support means on the elevator include a fixed base and a support platform mounted for low-friction horizontal movement with respect to the base in response to aligning forces exerted on the top of the stack by the guide means. Bias means are provided to urge the movable platform toward a home position.
