ABSTRACT:
A buffer device for buffering a flow of stacks of discrete objects between a stacking machine and a packaging machine is disclosed which buffer includes a plurality of individual trays mounted on carriers which carriers are mounted on a frame and driven about the periphery of the frame by a drive. A first number of stacks of objects is placed on a first number of carriers on a first side of the frame and a second number of stacks are removed from a second number of carriers on a second side of the frame where the first number can be greater than, less than or equal to the first number. The carriers clamp onto a continuously moving drive belt in a manner that allow the drive belt to slip through the carrier clamps when motion of the carriers is obstructed. A method of using the buffer device is also disclosed.
