1. A layer destacking system for destacking a layer from a stacked layer pallet load, the layer destacking system comprising:
a layer seating platform configured so as to seat the destacked layer on the layer seating platform, and having a conveying surface with a conveyance traverse direction that traverses the seated destacked layer off the layer seating platform;
a slip sheet detection sensor coupled to the layer seating platform and arranged to sense a slip sheet in contact with the seated destacked layer on at least one of an uppermost surface and a bottom surface of the seated destacked layer;
a slip sheet pickup removal mechanism extending at least in part over the layer seating platform and configured so as to engage, above the layer seating platform, the slip sheet contacting one of both the uppermost surface and the bottom surface of the seated destacked layer; and
a controller communicably coupled to the slip sheet detection sensor so as to receive a signal from the slip sheet detection sensor identifying presence of the slip sheet, the controller is configured to determine from the received signal the slip sheet contacting the at least one of the uppermost surface and the bottom surface of the seated destacked layer;
wherein the controller is operably connected to the slip sheet pickup removal mechanism so as to actuate the slip sheet pickup removal mechanism engaging the slip sheet contacting the one of both the uppermost surface and the bottom surface, and lifting the slip sheet effecting discharge of the slip sheet off the layer seating platform.
