ABSTRACT:
The machine comprises an oscillating chute (2) and a conveyor (3) feeding containers (25) to a height-adjustable conveyor belt (12) consisting of a number of parallel belts (13). Photosensors (27) detect incorrectly placed containers which are allowed to continue to a chute (38) and are returned by a conveyor belt (39) to the oscillating chute (2). A displaceable stop (18) halts correctly placed containers are lifted into a stack holder (31) and retained by grippers (35) that may be rotated by a rotating cylinder (34), thereby releasing the container stack after the pile holder has been tilted against a stacking table (36).
