Abstract: The present invention teaches a method for quickly and easily nesting and un-nesting bulk seed boxed. A first lower box is engaged with forks extending from a forklift truck, and the stacked boxes are elevated to a target height. Next, the forklift truck is advanced forward until the stacked boxes are in position in a box inverter apparatus, wherein the stacked boxes are positioned between opposing box engaging surfaces of rotary clamp pads. The rotary clamp pads engage the stacked boxes at a clamping location below the center of mass of the second, upper box unit. The forks of the fork truck carrying the first, lower box unit are then lowered until the first lower box unit is separated from the second, upper box unit, thereby affecting rotation of the second, upper box unit and rotary clamp pads until the second, upper box unit rotates a full 180 degrees to an inverted position.

Abstract: The present invention teaches a method used in connection with a forklift truck for quickly and easily nesting and un-nesting bulk seed boxes. A lower surface of the first lower box unit is engaged with forks extending from a forklift truck. The stacked first and second box units are then elevated to a target height. Next, the forklift truck is advanced forward until the stacked first and second box units are in a predetermined horizontal position in a box inverter apparatus, wherein the stacked first and second box units are positioned between opposing box engaging surfaces of first and second rotary clamp pads associated with the box inverter apparatus. The rotary clamp pads are then moved toward the stacked first and second box units until the opposing box engaging surfaces engage opposing outer surfaces of the second, upper box unit at a clamping location below the center of mass of the second, upper box unit.

Abstract: The present invention teaches an apparatus and method used in connection with a forklift truck for quickly and easily nesting and un-nesting bulk seed boxes. A box inverter apparatus includes first and second rotary clamp pads, each clamp pad having a box engaging surface and an opposing rear surface. The first and second rotary clamp pads are positioned such that the box engaging surfaces thereof face one another in a spaced apart relationship. First and second spindle and bearing assemblies are associated with and extend radially outwardly from the opposing rear surfaces of the first and second rotary clamp pads, respectively. Each of the spindle and bearing assemblies has a first end attached to the rear surface of the rotary clamp pad and a second end attached to a frame such that each spindle and bearing assembly permits rotation of the rotary clamp pad relative to the frame.
