Bin destacker and restacker

摘要

Means for destacking or restacking sequences of bins wherein the bins are transferred serially from their initial position to their final desired position by clamping assemblies located at the outer end of pivot arms, the pivot arms being capable both of vertical translation and of rotation while maintaining the vertical orientation of the bin being transferred. One or more photosensing devices is used to properly position the pivot arms and associated clamping assemblies relative to the uppermost bin in the stack to be transferred.
